Garrahan, Thomas Booth. "The market potential and economic feasibility of a wooden pallet bin leasing system." Thesis, Virginia Tech, 1985. http://hdl.handle.net/10919/45723.
Full textAbstract:
The concept of a bin leasing system represents an effort to use bins more extensively. In a leasing system one inventory of bins would be used by two‘or more annual users. System benefits would be lower per-use costs for the user and the opportunity for the lessor to make a profit.
In order to establish a working data base of information, a mailed questionnaire was sent to 333 fruit and vegetable processors. The response rate on the survey was 45%.
A typical bin is built of hardwood lumber, lasts about seven years, and costs an average of $36.53. Seventy-eight percent of the owners considered bin repair a problem, 85% thought bin transport was expensive, 96.5% agreed that bins were a significant investment. Overall, 66% considered bin leasing a viable option to ownership.
Eastern North Carolina was chosen as the most promising leasing system location. The system will cater to cucumber/pepper processors and sweet potato packers. The method chosen to establish the system is to contract with one or more large companies to supply, on a lease basis, the required replacement bins for future years.
A sample system was designed based on cost and revenue information received from area bin owners. Calculations yielded a net present value of $31,056.99 for a 15 year run of the system when using a discount rate of 12.5%.
The effects of changes in key variables were analyzed. The most dramatic changes in NPV were due to changes in bin life and per-bin revenues.Master of Science

Full textAbstract:
Pallets play a very important role in whole distribution systems through the supply chain. Such a fact alone shows the importance of pallets in today’s fast growing global logistics. Due to the increasing number of regulations and policies regarding natural resource conservations and also sustainable development, the issue of pallet utilization, reuse and recycling matters became the core concern in most of the researches performed in this field.As a consequence, the presented report discusses the current problems, requirements and debates around pallets utilization in distribution systems in depth along with the other affecting factors such as Cost, Environment, Materials, Sustainability, Information Technology and so forth. To achieve such goals, the first step is recognizing the mass Industrial production factors and global market requirements for the current and future of pallet utilization in order to achieve the desired efficiency and effectiveness in practice with focus on standardized pallets utilization in specific regions like European Union.The second step is the considering of various pallet types compatibility in different environments with respect to unit load assignments both at present and future. The third step is to challenge the obtained data and observed results and also, to verify them according to the foreseen future requirements, tendencies and demands of pallets and unit loads assignments through the international logistics providers. The last step which is as well the most important part of this thesis report is, to put the information together in order to clarify and specify the encountered difficulties regarding usage of pallets with concentration on cost, environment and ergonomic issues.

Runow, Björn. "Deep Learning for Point Detection in Images." Thesis, Linköpings universitet, Datorseende, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-166644.
Full textAbstract:
The main result of this thesis is a deep learning model named BearNet, which can be trained to detect an arbitrary amount of objects as a set of points. The model is trained using the Weighted Hausdorff distance as loss function. BearNet has been applied and tested on two problems from the industry. These are: From an intensity image, detect two pocket points of an EU-pallet which an autonomous forklift could utilize when determining where to insert its forks. From a depth image, detect the start, bend and end points of a straw attached to a juice package, in order to help determine if the straw has been attached correctly. In the development process of BearNet I took inspiration from the designs of U-Net, UNet++ and a high resolution network named HRNet. Further, I used a dataset containing RGB-images from a surveillance camera located inside a mall, on which the aim was to detect head positions of all pedestrians. In an attempt to reproduce a result from another study, I found that the mall dataset suffers from training set contamination when a model is trained, validated, and tested on it with random sampling. Hence, I propose that the mall dataset is evaluated with a sequential data split strategy, to limit the problem. I found that the BearNet architecture is well suited for both the EU-pallet and straw datasets, and that it can be successfully used on either RGB, intensity or depth images. On the EU-pallet and straw datasets, BearNet consistently produces point estimates within five and six pixels of ground truth, respectively. I also show that the straw dataset only constitutes a small subset of all the challenges that exist in the problem domain related to the attachment of a straw to a juice package, and that one therefore cannot train a robust deep learning model on it. As an example of this, models trained on the straw dataset cannot correctly handle samples in which there is no straw visible.

Full textAbstract:
I Aitiks dagbrottsgruva i norra Lappland bryts kopparmalm med hjälp av metoden pallbrytning. I korthet innebär det att omkring 200 borrhål borras vertikalt i berget och fylls senare med sprängämne. Vid detonationen frigörs en horisontell skiva, så kallad pall, från det omgivande berget. Aitik använder i dagsläget sin borrplan för bestämning av borrhålens längd. Emellertid överensstämmer inte alltid dessa längder med de önskvärda borrhålslängderna. Målet med projektet var att föreslå förbättrade metoder och tillvägagångsätt för att nå önskad nivå vid produktionsborrning. Under projektet har det studerats hur mycket borrplanen avviker från önskade borrhålslängder. Det har också undersökts i vilken utsträckning borrmaskinerna autonomt klarar av att beräkna korrekta hål-längder med hjälp av sitt navigationssystem. En borrmaskin i Aitik använder Trimbles navigationsplattform medan de övriga fyra använder Leica. Analyserna visade att Trimbles navigationssystem var mycket tillförlitligt att använda för hål-längdsbestämning, förutsatt att noggrann kalibrering utförts. Leicas navigationssystem visade sig vara mindre tillförlitligt, då det ”svajade” i höjdled: för samma punkt i rummet visades olika höjdledskoordinater vid olika tidpunkter. Den Leica-utrustade borrmaskinen som svajade mest hade variationsbredden 31,9 cm. Rekommendationerna är: * Att om borrplanen fortsättningsvis ska användas för hållängdsbestämning, rekommenderas att ”nollning” av borrmaskinen skall ske utan rotation. Nollning är den punkt som bestäms till borrstartspunkt under borrningens utförande. Våra tester visade att om nollning sker med rotation, kan borrkronan sjunka ned 20 cm i pallytan innan borrstart registreras. På grund av detta kan borrhålen bli för långa. * Att under en testperiod, låta navigationssystemet på maskinerna autonomt beräkna borrhålens längd. Under denna period bör regelbundna kontroller av navigationssystemet ske, för att säkerställa att höjdkoordinaterna håller sig inom bestämda gränser. Kontrolleras maskinernas navigationssystem regelbundet kan ett stort statistiskt underlag skapas, vilket kan användas vid ett långsiktigt beslut om navigationssystemet fortsättningsvis skall användas för bestämning av borrhålslängder.In the open pit mine Aitik, situated in the north of Lapland, copper ore is mined using the method pallet mining. In short, around two hundred boreholes are drilled vertically into the rock and subsequently filled with explosives. At detonation, a horizontal slice called a pallet is released from the surrounding rock. Today Aitik uses a drilling plan to decide the lengths of the boreholes. However, these lengths do not always correspond with the desired borehole lengths. The goal with the project was to find and suggest better methods and approaches to achieve desired levels of production drilling. During the project, studies have been made to see how much the drilling plan differs from the desired borehole lengths. The studies have also concerned the extent to which the drilling machines can make autonomic decisions determining the borehole lengths, using their navigation system. One drilling machine in Aitik uses a Trimble platform for navigation, while the other four use Leica. The analysis shows that the Trimble navigation platform was very reliable in deciding borehole lengths, provided that an accurate calibration was performed. The Leica navigation system turned out to be less reliable, since its height readings fluctuated: the same point in space would show as different coordinates of height at different points in time. The Leica-equipped power drill with the most fluctuation had a variation width of 31,9 cm. The recommendations are: * That, in the case of continuous use of the drill plan to determine borehole length, the “zero setting” of the power drill shall be made without drill rotation. The zero setting is starting point of the drilling operation. The tests showed that if the zero setting is done with rotation, the drill crown can sink 20 cm down into the pallet surface before drill start is registered. Because of this, the drilling holes can become too long. * That, during a test period, the navigation systems of the machines shall autonomously calculate and decide the borehole length. During this period, regular controls of the navigation systems should be made to ascertain that the coordinates of height remain within certain limits. Regular controls of the navigation systems can provide large amounts of statistical data, which can be used to make a long-term decision whether the navigation systems should continue to determine the borehole lengths.

Full textAbstract:
The aim of this work was to design the construction of transport equipment under industrial robot, pallet holder or other equipment. This manipulation device can be moved in one axis on a rigid guide. The device is designed for use in a linear manufacturing system for handling workpieces and tools. It is capable of operating two rows of machines when it is placed in the middle. The main function of this device is to extend the workspace to the carried devices. This type of construction can be used in combination with an industrial robot for other technological tasks such as welding or light machining. The main parts of this device include statically mounted beds that can be stacked behind each other to form optionally long conveyor paths and a positioning plate that moves along the path formed by these beds. An industrial robot, pallet holder or other device is attached to this positioning plate. In addition to the design itself, the thesis also includes a thorough research of the issue, further possibilities of solution in the form of concepts, verification of the structure by means of calculations and simulations and implementation of the solution into a specific production cell.

Full textAbstract:
The BMW Group uses load units for the transportation of assembly parts from the suppliers to the plants and for the internal material flow. This thesis analyses the advantageousness of introducing a load unit with a new size. There are three reasons why the current choice of containers is not sufficient. Firstly, there is a certain range of assembly parts that does not fit very well into the existing standard load units. Secondly, the average measurements of the parts have grown in the last years and thirdly, several of the existing containers leave unused space in the transportation vehicles.
For this the relevant costs and other, more qualitative aspects like the placing at the assembly line are considered. A container size is identified that offers a significant savings potential. For this potential the handling and transportation costs are identified as the relevant leverages. These costs are found to depend mainly on the utilisation degree of the load units.
To calculate the different utilisation degrees, a packing-algorithm in form of a four-block heuristic is applied and its results are extrapolated on the basis of existing BMW packing information. Thus, several assembly parts are identified that fit better into the suggested load unit than in the existing ones. These results are assessed using BMW’s expense ratios for handling and transportation. 80 parts are determined for which the migration to the new size would result in savings of more than 5,000 EUR for each per year in Dingolfing. Together, these parts offer a savings potential of about 0.9 million Euro.

Full textAbstract:
As an emerging form of renewable energy, horizontal wind turbines have experienced advancements in improving efficiency and reliability. These advances have pushed the limits of current technology used in wind turbines. Smart blades have been proposed as a method of addressing these limitations. Sensor integration within blade construction is the first step in development of smart blades. Thus, several low cost sensors were chosen, 1 axis strain gages, polyvinylidene fluoride films (PVDF), and single mode fiber optics either coated in acrylate or polyimide. To ensure successful bonding between sensor and composite two surface treatment techniques were developed. The first, dipping of the sensor into a bath of 20% by weight solution of nitric acid and the second was submersion of the sensor in the nitric acid for ten seconds prior to removal. These treatments were compared against sensors not surface treated prior to embedding. These sensors were embedded within samples created of fiberglass and epoxy or vinyl ester resin. Two different material tests were conducted. Tensile testing allowed for evaluation of sensor sensitivity, sensor failure point, material tensile modulus, and material tensile strength. Mode I fracture toughness evaluation, indicated the level of successful bonding which occurred during resin curing. Field Emission Scanning Electron Microscopy (FESEM) was conducted to further confirm the level of bonding between resin and sensor, post fracture. Results for embedded strain gages showed an adverse effect for vinyl ester samples. Epoxy samples fared better, thus concluding manufacturing success for epoxy samples, submersion being preferred, and alternative methods needed for vinyl ester samples. PVDF films had good qualitative FESEM images combined with increasing trends. It was concluded that integration for both resin groups with sensors submerged in nitric acid was successful. Fiber optics coated in acrylate also showed good bonding under FESEM imaging as well as testing. It was thus concluded that submersion was the preferred treatment. Lastly, fiber optics coated in polyimide embedded in vinyl ester composites showed significant drawbacks and it was concluded that alternative methods need exploration. Those embedded in epoxy were successfully integrated and submersion in nitric acid showed the most potential.

Target of the submitted work was a proposal of a new type of shelf stackers in the range from 8 to 36 m that are working in fully automated warehouses. By using a fully automated storage system all human supervision in ordering pallets in a warehouse are canceled and everything is taken over by the control system. These stores are very efficient and save both time and money. With regard to safety requirements, regular inspections should be provided to the system. At the beginning of this work, there was done a short introduction to the particular study including the description of basic parts of the shelf stackers. Consequently, there were done relevant computations for the drag device and its drive, drives for the travel and the finite method was used to the stress analysis of the mast shelf stacker. In the last part of this thesis is done a safety concept.

Full textAbstract:
The U.S. food system is afflicted by a variety of social, ecological, and economic predicaments including hunger, food access inequalities, soil and water degradation, and lack of community control over food. Scholars and activists agree that in order for U.S. food movement actors to affect significant system-wide change, players must bridge a multitude of issue areas and ideological differences. Despite thorough analyses of local and regional food systems, little research has been conducted on either national level advocacy perspectives or the ties that bind and divide food advocacy coalitions. This dissertation's central research question examines how the U.S food advocacy movement works to resist the hegemonic domination of the national food system by state and corporate actors. To answer this question, this project develops a social network analysis of 71 national-level food advocacy actors, compiles web-based issue and tax data, and conducts 36 semi-structured interviews with senior food activist staff. Social movement literature and Antonio Gramsci's concepts of counter-hegemonic movements and wars of position inform the findings and reveal the national food movement's nascent propensity to unite cultural and class struggles to create significant pressure for systematic change in the U.S. food system. Additionally, this research tests existing theoretical work related to the food advocacy network and distinctions between interest group and social movement type organizations. This dissertation reveals that despite most activists' conviction that a constellation of agri-business and state policies dominate the U.S. food system, significant network rifts, framing dilemmas, strategic conflicts, and resource complexities prevent national food activists from generating a robust challenge to hegemonic food system actors.

Full textAbstract:
In recent years, Internet-of-Things technology (IoT) has been the subject of research in a diverse field of applications, given its essential role in transitioning society towards a more interconnected paradigm of conducting manufacturing, logistics, services, and business, what is also known as Industry 4.0. Consistent with this line of research, this project addresses the application of IoT in distribution packaging as a way to better understand supply chain conditions.
Specifically, this work presents an operational concept for a system that implements IoT technology in the pallets that are used to move products along supply chains and serve as a vehicle to gain insight into the conditions experienced by products and unit loads. The development of this operational concept leverages a systems engineering framework to discover user needs, and stakeholders, and apply model-based systems engineering to create system models that capture expected system behavior and the outputs necessary to create value for the user.
A semi structured interview was conducted with eleven companies in order to discover user needs related to their packaging during distribution processes in their supply chain. A system operational concept was developed through use cases, concept of operations, and formal modeling using Cameo System Modeling Software. A review of sensor and communication technologies is presented, as well as a description of the challenges and future research opportunities for the proposed operational concept in distribution packaging.
The application of systems engineering framework, and model-based systems engineering to the distribution packaging domain brings clarity to problem formulation in order to lay-out solid value propositions for the adoption of IoT technologies, and to ensure successful realization of systems that achieve customer satisfaction.
This work offers three main contributions. First, it provides an identification and description of the needs that industrial companies have in relation to their product and packaging performance during distribution operations. Secondly, it shows how a systems-based approach, leveraging on model-based systems engineering can be employed to conceptualize systems that use innovative technologies like IoT in the domain of distribution packaging. Third, it provides an overview of open research challenges and practical considerations for the implementation of IoT technology in the field of distribution packaging.Master of Science
In 2007, The World Bank published a study which states that "eighty percent of US trade is carried on pallets" (Raballand and Aldaz-Carroll, 2007). Furthermore, in the year 2015, a report estimated that there would be 2.6 billion pallets circulating in the United States by the year 2017 (Freedonia Group, 2015). Pallets are ubiquitous and a key component of distribution operations in supply chains, as they transport goods, and are the main interface that connects material handling equipment and packaged products (White and Hamner, 2005). Based on that distinctive characteristic, this study contends that pallet can be used as a window to gain insight into the realities of what is experienced by products and packaging during distribution. This can be done by using sensors imbedded in pallets to capture data of interest about the physical conditions in the supply chains, which opens the potential for more customized and optimized packaging design, supported by more reliable and representative information. This idea is particularly relevant, as established protocols for packaging testing are limited in their capacity to accurately simulate the real-world conditions that occur in the supply chain. This has resulted in suboptimal packaging design (Rouillard, 2008) that decreases the efficiency of logistics operations. This study found that industrial companies are most concerned with avoiding damage that their products can suffer during transportation as a result of temperature, relative humidity, shock, and vibration. Thus, it is necessary to gather data about these distribution parameters for product shipments. Using a model-based system engineering approach, an operational concept is proposed to show what is needed from a system to be able to track these parameters. Furthermore, a review of current available technology for IoT is presented, as well as an examination of the challenges posed to the realization of the proposed operational concept, including factors like cybersecurity, and energy resources constraints. This work offers three main contributions. First, it provides an identification and description of the needs that industrial companies have in relation to their product and packaging performance during distribution operations. Secondly, it shows how a systems-based approach, leveraging on model-based systems engineering can be employed to conceptualize systems that use innovative technologies like IoT in the domain of distribution packaging.

Full textAbstract:
Broad whitefish, Coregonus nasus, is an important subsistence fish species in Arctic North America, yet virtually nothing is known regarding the genetic population structure of Nearctic populations of this species. In this thesis, microsatellite DNA variation was assayed among 1213 broad whitefish from 47 localities throughout North America, with emphasis on the Mackenzie River system, Northwest Territories. Specifically, I examined geographic variation in allele frequencies to assess how historical factors (Pleistocene glaciations) have shaped the current structuring of genetic variability and population differentiation. Microsatellite data was also used to resolve the relative contributions of broad whitefish populations to subsistence fisheries in the Mackenzie River system. Overall, broad whitefish exhibit relatively high intrapopulation microsatellite variation (average 12.29 alleles/locus, average HE = 0.58) and there were declines in these measures of genetic diversity with distance from putative refugia suggesting historical factors, namely post-glacial dispersal, have influenced current microsatellite variation. Interpopulation divergence was low (overall FST = 0.07), but the main regions assayed in this study (Russia, Alaska, Mackenzie River and Travaillant Lake systems) are genetically differentiated. Strong isolation-by-distance among samples was resolved when including only those populations occupying former Beringia, but not when assaying those at the periphery of the range in the Mackenzie River system, suggesting that broad whitefish in the Mackenzie system have not occupied the region long enough since their invasion post-glacially to have approached equilibrium between gene flow and drift. Mixture analysis indicated that most fish from the lower Mackenzie River subsistence fishery originated from the Peel River, highlighting the importance of this tributary. Additionally the mixture analysis provides evidence for a putative riverine life history form in the Mackenzie River. My results indicate that glaciation and post-glacial colonization have been important in shaping the current genetic population structure of North American broad whitefish. They also illustrate the utility of microsatellite DNA to delineate population structure and patterns of genetic diversity in recently founded populations in addition to resolving contributions to fisheries. My data also support the hypothesis that there are several designatable units of conservation among broad whitefish populations and that management strategies should be implemented accordingly.

It is located on the theoretical NW extension of the Haswell-Salt Lake Morrow sandstone producing trend and Morrow sandstones have found in some of the available wells in the area. The productive Morrow sandstones are fluvial channel deposits that are encased by marine shales. The distribution of the Morrow channel system is difficult to define from either data obtained from sparsely located wells alone, or directly from seismic data due to low acoustic contrast between fluvial sandstones and marine shale. Therefore, this study has used a correlation of well log data to understand regional stratigraphy of the selected study area and seismic attributes were used to develop a workflow to define the Morrow sandstone channel system in the Manassas prospect. Well logs from forty wells were used to define the early Pennsylvanian strata (Marmaton, Cherokee, upper and lower Atoka, upper and lower Morrow) and underlying Mississippian unit (St. Louis). The formation data were used to visualize the regional stratigraphy using isopach maps and stratigraphic cross sections. The acoustic and density logs from the Lockwood 27-22 well located in the Manassas field, were used to generate the synthetic seismogram for the purpose of seismic horizons interpretation. The upper Morrow isochron thick was defined using upper and lower Morrow time structure maps. The channel infill system was first detected using the Chaos attribute that identifies reflectors associated with channel infills that are normally chaotic signals with low consistency. The observation was confirmed using, Variance attribute that analyzes signal coherency, and estimates trace to trace variance. The amplitude attributes (RMS Amplitude – iterative attribute, and Envelope) highlight both channel infills and bright spots. The Genetic Inversion identifies relative variations of rock properties. The Generalized Spectral Decomposition attribute was used to visualize the detailed channel morphology through generating a RGB blending model as the final step. This study shows that the Morrow channel sandstones are present across the Manassas prospect and are interpreted as a composite meandered and anastomosed channel system. The observed high amplitude variations are interpreted as tuning effects of thin beds and relative lithological changes caused by variations of rock properties such as density and porosity.

Full textAbstract:
Logistics plays a crucial role in companies’ ability to sustain competitive on the market. Time is regarded as one of the important metric in terms of logistics, since time influences the lead time of the products, which results in the vital advantage of speed. The recent business environment forces Kinnarps Production AB, a manufacturer of furniture, to optimize their inventory material flow in a way of increasing their capability and capacity to load more distribution containers with goods daily. The present circumstances of the material flow are associated with number of negative factors. An automated guided vehicle (AGV) system is operating and handling the distribution of goods. Wrong sequence of activities, long transportations, high transportation delays, waiting time, varying numbers of AGVs, wastes, bottlenecks are among the important issues to be considered.
The purpose of this thesis is to analyze the material flow in Kinnarps Production AB’s inventory seven and to improve the AGV system activities within.
Concepts associated with identifying waste were used by separating value-adding activities from the non-value added ones. The usage of ideal reference systems techniques were the base for identifying problems. Concrete literature regarding AGV’s design system was applied in establishing different statements about the material flow and identification of problems. Different methods and techniques were used in approaching the research, but most above others is the case study approach. Numerous amounts of secondary data have been employed in verifying the collection of other data carried out by primary data collection as well as verifying the qualitative and quantitative analysis.
A mapping of the current system was established with respect to orders, times and distances. Numbers of congestion points were identified, non-value adding activities were eliminated or decreased, rearrangement of sequencing of different activities was considered and different pallets arrangement system was established. A stochastic model was used in identifying the AGV’s time variables in the system and estimating appropriate amount of AGVs within the inventory.
All the findings from different calculations and estimations were associated with Kinnarps Production’s future increased demand. Different issues and considerations were analyzed and appropriate suggestions were given for elimination of the negative factors in the inventory or their decrease. Among the most influencing results was the proper amount of AGVs in the inventory area, pallets rearrangement, different stocking policy, rearrangement in the sequence of activities, increase of the buffer for pallets used for loading containers, new conveyor system for the incoming goods in the inventory, transportation layout changes resulting in blocking free routines, separate control system, decrease of the effect of stoppages. All these findings are considered to optimize the material flow and increase the system capacity contributing to an increase of the daily containers outgoing from Kinnarps Production AB.

Full textAbstract:
Eastern black nightshade, Palmer amaranth, and common pokeweed are three hard to control weed species on the Eastern Shore regions of Virginia and Maryland. Herbicide resistance and lack of herbicide efficacy further complicate the job of controlling these weeds. Studies were conducted on each of these weeds in order to determine herbicide efficacy and potential herbicide resistance. In addition, the translocation and metabolism of 14C-glyphosate was studied in common pokeweed. This research identified a population of eastern black nightshade that was differentially sensitive to families of ALS-inhibiting herbicides, with tolerance to members of the sulfonylurea family, but controlled with herbicides of the imidazolinone family. A population of Palmer amaranth was found to be glyphosate-resistant, but herbicide programs were identified that could control this biotype in soybean and corn systems. Experiments on the fate of glyphosate in common pokeweed indicated that glyphosate does not readily translocate from treated foliage to other plant parts, which may contribute to shoot regeneration from taproots following glyphosate treatment. Taken together, this research highlights the important weed control issues, including resistant and perennial weeds in agronomic crops that have arisen in Eastern Shore agriculture. This work will help growers to better assess their particular control issues, and take appropriate steps to mitigate any problems.Ph. D.

Full textAbstract:
It is widely acknowledged that international trade is a major pathway for the spread of invasive species. International agreements and domestic legislation aim to reach a balance between facilitating trade and providing nations with the right to protect their
environmental, public and economic health. This is achieved through the development of standards that prescribe procedures that must be followed before a commodity is imported. Under Section 22 of the Biosecurity Act (1993) Biosecurity
New Zealand of the Ministry of Agriculture and Forestry (MAF) develops import health standards for the importation of commodities and sea containers and for the approval and management of transitional facilities.
Under current regulations, before being allowed to enter New Zealand, a sea container must first be accompanied by appropriate documentation for the sea container itself and any contents (this includes cargo manifests, any required treatment certificates for the cargo and cleaning certificates for the sea container itself). Upon arriving in New Zealand the sea container is transported to a transitional facility for inspection and unloaded once biosecurity clearance has been obtained. There are approximately 7,000 transitional facilities (both on and off wharf) throughout New Zealand and
inspections are conducted by persons that have obtained accreditation from MAF for inspections (MAF accredited persons).
Based on current importation procedures and other information made available, mathematical models were developed for three sea importation pathways (sea containers, woodpackaging and used vehicles) that involved the inspection of imported units by MAF accredited persons. These models were designed to predict the effectiveness of the current border inspection policies and procedures. Inspection accuracy was found to have the most influential impact on slippage (the rate at which
contamination passes through border procedures undetected) along the measured pathways. Under current conditions, an estimated 5.75% of all sea containers, 4.12% of all sea containers containing woodpackaging and 1.63% of all used vehicles that
enter New Zealand annually are contaminated in some manner despite having biosecurity clearance. A 3% increase in inspection efficiency reduced slippage to 0.5% of sea containers, 2.16% of woodpackaging and 0.001% of used vehicles
entering New Zealand annually.
Given that the accuracy of the inspection was the most influential aspect of the border management procedures, mathematical models were develop to predict the cost of compliance recovered by MAF if all inspections were conducted by MAF inspectors
as apposed to MAF accredited persons. Under current regulations the cost of compliance (if MAF inspector conducted inspections of all imported units) was estimated to be $117.36 million for sea containers, $35.16 million for woodpackaging
and $5.44 million for used vehicles. Increasing the inspection accuracy to the ideal 100% increased the cost of compliance by 75.36%, 61.96% and 61.92% for sea containers, woodpackaging and used vehicles respectively.
These findings indicate that Government investment in the training of inspectors
throughout New Zealand would improve current border detection rates. Under current regulations, the cost incurred by MAF inspectors inspecting all imported units is recoverable. Currently the cost of compliance is approximately 1% of the value of
annual imports. These costs are seen by the import sector as part of their daily business and understand that these measures are in place for the long term sustainability of their businesses (Anon. 2005).

Full textAbstract:
This study investigates evidence for linkages and fault interactions centred on the Cust Anticline in Northwest Canterbury between Starvation Hill to the southwest and the Ashley and Loburn faults to the northeast. An integrated programme of geologic, geomorphic, paleo-seismic and geophysical analyses was undertaken owing to a lack of surface exposures and difficulty in distinguishing active tectonic features from fluvial and/or aeolian features across the low-relief Canterbury Plains.
LiDAR analysis identified surface expression of several previously unrecognised active fault traces across the low-relief aggradation surfaces of the Canterbury Plains. Their presence is consistent with predictions of a fault relay exploiting the structural mesh across the region. This is characterised by interactions of northeast-striking contractional faults and a series of re-activating inherited Late Cretaceous normal faults, the latter now functioning as E–W-striking dextral transpressive faults. LiDAR also allowed for detailed analysis of the surface expression of individual faults and folds across the Cust Anticline contractional restraining bend, which is evolving as a pop-up structure within the newly established dextral shear system that is exploiting the inherited, now re-activated, basement fault zone. Paleo-seismic trenches were located on the crest of the western arm of the Cust Anticline and across a previously unrecognised E–W-striking fault trace, immediately southwest of the steeply plunging Cust Anticline termination. These studies confirmed the location and structural style of north-northeast-striking faults and an E–W-striking fault associated with the development of this structural culmination. A review of available industry seismic reflection lines emphasised the presence of a series of common structural styles having the same underlying structural drivers but with varying degrees of development and expression, both in the seismic profiles and in surface elevations across the study area. Based on LiDAR surface mapping and preliminary re-analysis of industry seismic reflection data, four fault zones are identified across the restraining bend structural culminations, which together form the proposed Oxford–Cust–Ashley Fault System.
The 2010–2012 Canterbury Earthquake Sequence showed many similarities to the structural pattern established across the Oxford–Cust–Ashley Fault System, emphasising the importance of identification and characterization of presently hidden fault sources, and the understanding of fault network linkages, in order to improve constraints on earthquake source potential. Improved understanding of potentially-interactive fault sources in Northwest Canterbury, with the potential for combined initial fault rupture and spatial and temporal rupture propagation across this fault system, can be used in probabilistic seismic hazard analysis for the region, which is essential for the suitability and sustainability of future social and economic development.

Full textAbstract:
L’estimation fonctionnelle basée sur les espaces de Hilbert à noyau reproduisant demeure un sujet de recherche actif pour l’identification des systèmes non linéaires. L'ordre du modèle croit avec le nombre de couples entrée-sortie, ce qui rend cette méthode inadéquate pour une identification en ligne. Le critère de cohérence est une méthode de parcimonie pour contrôler l’ordre du modèle. Le modèle est donc défini à partir d'un dictionnaire de faible taille qui est formé par les fonctions noyau les plus pertinentes.Une fonction noyau introduite dans le dictionnaire y demeure même si la non-stationnarité du système rend sa contribution faible dans l'estimation de la sortie courante. Il apparaît alors opportun d'adapter les éléments du dictionnaire pour réduire l'erreur quadratique instantanée et/ou mieux contrôler l'ordre du modèle.La première partie traite le sujet des algorithmes adaptatifs utilisant le critère de cohérence. L'adaptation des éléments du dictionnaire en utilisant une méthode de gradient stochastique est abordée pour deux familles de fonctions noyau. Cette partie a un autre objectif qui est la dérivation des algorithmes adaptatifs utilisant le critère de cohérence pour identifier des modèles à sorties multiples.La deuxième partie introduit d'une manière abrégée le palier magnétique actif (PMA). La proposition de contrôler un PMA par un algorithme adaptatif à noyau est présentée pour remplacer une méthode utilisant les réseaux de neurones à couches multiplesFunction approximation methods based on reproducing kernel Hilbert spaces are of great importance in kernel-based regression. However, the order of the model is equal to the number of observations, which makes this method inappropriate for online identification. To overcome this drawback, many sparsification methods have been proposed to control the order of the model. The coherence criterion is one of these sparsification methods. It has been shown possible to select a subset of the most relevant passed input vectors to form a dictionary to identify the model.A kernel function, once introduced into the dictionary, remains unchanged even if the non-stationarity of the system makes it less influent in estimating the output of the model. This observation leads to the idea of adapting the elements of the dictionary to obtain an improved one with an objective to minimize the resulting instantaneous mean square error and/or to control the order of the model.The first part deals with adaptive algorithms using the coherence criterion. The adaptation of the elements of the dictionary using a stochastic gradient method is presented for two types of kernel functions. Another topic is covered in this part which is the implementation of adaptive algorithms using the coherence criterion to identify Multiple-Outputs models.The second part introduces briefly the active magnetic bearing (AMB). A proposed method to control an AMB by an adaptive algorithm using kernel methods is presented to replace an existing method using neural networks

Objetivo: Os indivíduos com fissura labiopalatina vivenciam um desequilíbrio morfofuncional desde a vida intrauterina influenciando o crescimento craniofacial e o desempenho das funções orais. O objetivo deste estudo foi avaliar a força e a mobilidade da língua em indivíduos com fissura labiopalatina operada, bem como de um grupo controle formado por indivíduos sem esta malformação e com boa relação dento-oclusal, para verificar a relação entre a força e a mobilidade da língua; a relação entre a força da língua e as funções de respiração, mastigação, deglutição e fala; assim como a diferença quanto a força e a mobilidade da língua entre os grupos. Método: Após aprovação do Comitê de Ética em Pesquisa, foram avaliados 59 indivíduos com idade entre 18 e 28 anos (média=23 anos e 3 meses), de ambos os gêneros, 30 com fissura unilateral completa de lábio e palato reparada e 29 com boa relação dento-oclusal, sem fissura labiopalatina e outras malformações. Foi realizado o exame miofuncional orofacial (MBGR) para verificar a mobilidade da língua e as funções de respiração, mastigação, deglutição e fala. Imagens do exame foram registradas e analisadas por três examinadores, com boa concordância entre eles verificada pela medida Kappa. O exame da força da língua utilizou o instrumento Iowa Oral Performance Instrument (IOPI) nas provas de elevação, lateralização para a direita e para a esquerda e protrusão da língua, além do teste de resistência. As correlações entre a força e a mobilidade da língua e, entre a força da língua e as funções de respiração, mastigação, deglutição e fala foram estabelecidas pelo Coeficiente de Correlação de Spearman, já a diferença quanto a força e a mobilidade da língua entre os grupos foi verificada pelo teste de Mann-Whitney. Resultados e Conclusão: Na amostra estudada, a relação significativa entre a força e a mobilidade da língua, bem como entre a força da língua e as funções de respiração, mastigação, deglutição e fala não foi verificada. Já a força e a mobilidade da língua foram menores para o grupo estudo.Objective: Cleft lip and palate individuals experienced a morphofunctional imbalance since intrauterine life influencing on craniofacial growth and oral function performance. This study aimed to evaluate the tongue strength and mobility of these individuals compared with those of a control group without cleft lip and palate and with good occlusal relationship, to verify the relationship between tongue strength and mobility; tongue strength and the functions of breathing, mastication, swallowing, and speech; as well as the difference between groups in the strength and tongue mobility. Method: After the approval of the Ethical Committee in Research, 59 individuals aged between 18 and 28 years (mean=23 years and 3 months), both genders, were evaluated comprising 30 individuals with repaired complete cleft lip and palate and 29 individuals with good occlusal relationship and without cleft lip and palate and other malformations. The orofacial myofunctional evaluation (MBGR) was conducted to verify the tongue mobility and the functions of breathing, mastication, swallowing, and speech. The images of the evaluation were recorded and analyzed by three examiners with good agreement among them verified by Kappa test. The evaluation of the tongue strength used the Iowa Oral Performance Instrument (IOPI) during the elevation, left and right lateralization and protrusion of the tongue and endurance test. The correlations between the tongue strength and mobility, and among tongue strength and the functions of breathing, mastication, swallowing, and speech were established by Spearman Correlation Coefficient, already the difference in the tongue strength and mobility between groups were assessed by the Mann-Whitney test. Results and Conclusion: In the studied sample, the significant relationship between tongue strength and mobility and among tongue strength and the functions of breathing, mastication, swallowing, and speech was not verified. However the tongue strength and mobility were lower in the study group.

Full textAbstract:
Improvements in fatigue and quality of life observed in primary and secondary progressive multiple sclerosis (MS) patients adhering to a modified Paleolithic dietary intervention (MPDI), nutritional supplementation, exercise, and neuromuscular electrical stimulation regime are hypothesized to be due primarily to the effect of diet. However, no research has been conducted evaluating effects of the dietary intervention alone thus, the purpose of this research was to evaluate a MPDI in the treatment of Relapsing-Remitting Multiple Sclerosis (RRMS). We tested effects of the MPDI in seventeen men and women (mean age: 36.3 ±4.7 years) with neurologist-verified RRMS. Nine subjects (one male) were randomized to a "usual care" (control) group and eight subjects (one male) were taught the MPDI. Both groups adhered to their assigned protocol for three months.
Significant improvement was seen in Fatigue Severity Scale (FSS, p=0.03), Multiple Sclerosis Quality of Life-54 Physical Health (MSQOL-P, p=0.03), and Mental Health (MSQOL-M, p=0.02) scores from baseline in MPDI subjects compared to controls. Increased vitamin K serum levels (p=0.02) were also observed in MPDI subjects at three months compared to controls. Significantly reduced time to complete 9-Hole Peg Test (9-HPT) with the dominant hand (p=0.02) was also observed. Our results indicate trends for improved non-dominant 9-HPT (p=0.05), Metabolic Equivalent Tasks (METs, p=0.08), and 25-Foot Walk (25-FW, p=0.09) scores from baseline in MPDI subjects compared to controls.
A Paleolithic diet may be useful in the treatment and management of MS, by reducing perceived fatigue, increasing mental and physical quality of life, increasing exercise capacity, and improving hand and leg function. The MPDI may also reduce inflammation as evidenced by increased vitamin K serum levels.

Full textAbstract:
Es wurde eine Datenbankmanagementsystem-Anwendung zur Dokumentation von Patienten mit Lippen-Kiefer-Gaumenspalten entwickelt. Ziel des Computerprogramms ist, anhand großer Patientenzahlen weitere statistisch abgesicherte Daten zur Heredität, anderen ätiologischen Faktoren, Epidemiologie und Therapiebewertung zu gewinnen. Besonderes Augenmerk wurde auf Angaben zu möglichen ursächlichen Faktoren der Spaltentstehung gelegt. Möglicherweise ergeben sich doch einmal durchgreifende präventive Maßnahmen bei Risikoschwangerschaften. Die Auswertung großer Patientenkollektive (seit 1948 etwa 3000 Spaltpatienten an der Charité) im objektiven Vergleich mit anderen Behandlungszentren kann zur Therapieoptimierung beitragen. Zur Analyse werden die funktionellen und aesthetischen Behandlungsresultate in Abhängigkeit vom Therapieverfahren eingeschätzt. Die Gesamtbehandlung erstreckt sich über 20 Jahre. Eine endgültige Ergebnisbeurteilung kann erst nach dieser Zeit erfolgen. Es muß von einer großen Variationsbreite der Behandlungsmodelle ausgegangen werden. Diese müssen an großen Patientenkollektiven statistisch in ihrem Erfolg abgesichert werden. Das Projekt steht im Konsens mit den Empfehlungen des interdisziplinären Arbeitskreises Dokumentation der Arbeitsgemeinschaft Lippen-Kiefer-Gaumenspalten der Deutschen Gesellschaft für Mund-, Kiefer- und Gesichtschirurgie. Die Anwendung wurde auf Basis eines relationalen Datenbankmanagementsystems entwickelt. Das Programm zeichnet sich durch einfache Bedienbarkeit und schnelle Datenerfassung aus. Es ist als detaillierte Erfassung konzipiert. Verschiedenartige Eingabeerleichterungen wurden eingearbeitet. Die Datenerfassung ist weitgehend standardisiert und skaliert. Voraussetzung für diese Eigenschaften, die in ihrer Gesamtheit einen Fortschritt im Vergleich zu vorgenannten anderen Systemen darstellen, war die rasante Entwicklung der Hard- und Softwaretechnik. Nunmehr ist es problemlos möglich, die Datenfülle zu bewältigen. Schon für den einzelnen Patienten besteht durch die vielen beteiligten Fachgebiete, diverse Behandlungsmaßnahmen und wiederholte Kontrolluntersuchungen ein beachtlicher Dokumentationsbedarf. Bei den für die statistische Auswertung nötigen hohen Patientenzahlen resultieren tausende Datensätze. Der erreichte Stand ist nicht endgültig. Das Programm kann ständig weiterentwickelt und angepaßt werden. Bezugnehmend auf andere Systeme soll der interdisziplinäre Charakter noch einmal betont werden. Dafür spricht unter anderem die Netzwerkkompatibilität. Im Wechselspiel mit der Kieferorthopädie, der Hals-Nasen-Ohrenheilkunde, Pädiatrie, Logopädie sowie der konservierenden Zahnheilkunde ergibt sich eine gegenseitige Beeinflussung. Das fand Berücksichtigung bereits im anamnestischen Bereich, setzt sich bei der Diagnose und Befunddokumentation fort. Auch die Menügestaltung ist darauf abgestimmt. Die Wechselwirkung der beteiligten Fachgebiete zu optimieren, ist das Ziel der Auswertung großer Patientenkollektive. Dazu sind ausgezeichnete Voraussetzungen geschaffen worden. Größte Patientenkollektive können nach beliebigen Kriterien und deren Verknüpfung in beeindruckender Schnelligkeit ausgewertet werden. Die Anwendung moderner Erfassungssysteme und insbesondere die Archivierung und Bearbeitung visueller Befunde besitzt nicht nur wissenschaftlichen Wert in ihrer Auswertung oder der Therapieplanung, sondern kann im Praxisbetrieb motivierende Wirkung auf den Patienten haben. Er fühlt sich optimal mit modernsten Mitteln betreut, was die Compliance erhöhen kann. Die eingehende Beschäftigung mit seinen Befunden beziehungsweise mit den Eltern bezüglich der Krankengeschichte vermittelt dem Einzelnen, daß sein Schicksal nicht nur für ihn wichtig ist, sondern sich in die Gesamtheit der Bemühungen einordnet, die Prävention und Therapie der Spaltbildungen zu verbessern.The efforts in the past to improve the treatment of patients suffering from cleft lip and palate as well as to better understand the etiology of clefts have shown that a large number of cases with very large amount of data will normally have to be assessed considering the natural variation of the cleft lip and palate and the true effects to be apparent clinically and statistically. With the help of computer supported databases it is possible to keep comprehensive records about anamnestic information and results of clinical examination before and after all types of treatment including the assessment of the standard of outcome. If necessary the future treatment approaches can be altered. Therefore a computer supported database system using the latest features of object orientated relational database management systems was developed. The efforts of the German Society Of Maxillofacial Surgery to standardize the clinical records and treatment evaluations were considered. The introduced system features network compatibility, high performance query tools and can be managed by average computer users. Running it on actual customary hardware the processing speed considering the very large amount of data to be collected from thousands of patients with often more than 18 years of treatment is excellent. The introduced system contributes to the general approach to improve the treatment outcome and to better understand the etiology of cleft lip and palate.

Full textAbstract:
La agricultura es una de las actividades económicas más importantes en el Perú llegando a tener una gran variedad de cultivos de exportación. Pero a nivel nacional, solo unas cuantas han logrado la Denominación de Origen, como es el caso del grano seco de pallar en la región Ica. Este reconocimiento, junto con su alto valor nutricional, ha permitido duplicar su producción y exportación en los últimos 10 años.
Sin embargo, la inadecuada forma en que se realiza una de las etapas principales, la selección del grano por calidad, trae problemas como imprecisiones en la calidad final del lote, repeticiones del proceso y, ya que este es un proceso manual, genera fatiga en el personal que ejecuta las operaciones. Las causas del problema están relacionadas con el actual procedimiento subjetivo y la no existencia de tecnología adecuada.
Por ello, en este estudio se desarrolla un sistema mecatrónico que permite la selección automática de pallares cuyos criterios de selección se toman de la Norma Técnica Peruana para exportación de pallar, la NTP 205.019: 2015. De esta forma, se alcanza mantener un proceso objetivo, estandarizado, de mayor precisión y de reducido trabajo manual utilizando tecnologías modernas.
El producto final es un prototipo automatizado con fabricación modular que clasifica los granos de pallar seco (aceptado o rechazado) utilizando algoritmos de procesamiento de imágenes y luego descarta los granos defectuosos mediante preactuadores neumáticos. Además, se utilizan transportadores vibratorios para movilizar a los granos de acuerdo a la necesidad. Finalmente, el hardware y software son implementados conforme a estándares y buenas prácticas de automatización industrial.Agriculture is one of the most important economic activities in Peru, having a great variety of export crops. But only a few have achieved the Denomination of Origin at the national level, as is the case of the dry lima bean in the Ica region. This recognition, together with its high nutritional value, has allowed its production and exportation to double in the last 10 years. However, the inadequate way in which one of the main stages is carried out, the grain sorting by quality, brings problems such as inaccuracies in the final quality of the batch, repetitions of the process and, since this is a manual process, fatigue in the personnel. The causes of the problem are related to limited technology and the current subjective procedure. Therefore, in this study a mechatronic system is developed that allows the automatic lima beans sorting whose criteria are based on the Peruvian Technical Standard for lima beans export, the NTP 205.019: 2015. In this way, an objective process would be maintained, standardized, with reduced manual labor using modern technologies. The final product is an automated prototype with modular manufacturing that sorts dry lima beans (accepted or rejected) using image processing algorithms and then discards the defective ones using pneumatic actuators. In addition, vibratory conveyors are used to move the grains according to need. Finally, the hardware and software are implemented according to standards and good industrial automation practices.

In it two stamped machines were used, which had to stamp fixed numbers of calibration test (a paper with specially made, same size and various colours quadrants for spectrofotometer, where is different number of all four CMYK bitmap colour dots), which colour intensity was measured with using spaectrofotometer “Efi ES-1000”. The results have shown that “Xerox” machine has larger colour reproduction depth comparing to “Minolta” . This condition is made because of varnish that covers stamp. It creates specular effect and eliminates resolved light that comes to measuring devices. Self calibrating system cracks were discovered as well. Also two machines have to be calibrated after fixed number of stamps. Thesis has 7 parts: Introduction, literature review, research methodology, results, results discussion, conclusion and recommendation, literature list, appendix. Thesis consist of: 57p. text without appendix, 3 tables, 33 pictures, 15 bibliographical.

"Mobilising action through management email texts: the negotiation of evaluative stance through choices in discourse and grammar." Publisher:University of New South Wales.

Full textAbstract:
This thesis is concerned with explicating the role of language in mobilising action through management emails. Situated within the context of organisational change in a globalised manufacturing business, the project is framed by behavioural observations from management scholars Palmer and Hardy (2000) of mobilisation strategies that utilise linguistic resources since they: (a) involve a sense of obligation or inclination in directives; (b) show how co-operation will produce mutual benefits; (c) construct desired actions as legitimate, beneficial or inevitable; and (d) use past or anticipated meanings, for or against certain actions. Systemic Functional Linguistics is the underlying framework employed to provide a theoretically principled account of the intuitively derived observations from Palmer and Hardy (2000) which are applied to a sample of twenty-seven email texts, through corpus- and text-based analysis. A major finding is that the representation of action is enacted interpersonally through the verbal group. This view complements experientially dominated accounts of the verbal group which focus on the tense system. Further, action is found to be motivated through the negotiation of evaluative stance. By relating the grammar of the verbal group as well as other resources to the discourse semantics of Appraisal, modulation (of obligation or inclination) is found to be enabled by both negative as well as positive judgements of capacity. Specifically, judgements of capacity are re-interpreted as invocations of high obligation as managers seek to mobilise (further) positive performance. The analysis demonstrates that elements in the verbal group (complex) and Appraisal co-opt action through enabling positioning of the writer, in terms of assessing and grading categorical meanings, manipulating interpersonal time, or foregrounding solidarity. A significant contribution to the thesis is an extension of the system of GRADUATION: FOCUS (Hood, 2004a) through the demonstration of how resources of the verbal group negotiate expectations of appearances and achievements. This study has also extended the resources of GRADUATION: FORCE by applying it to the management context. The practical contribution of the study is that these insights may more explicitly inform management training and enable managers to participate more effectively within their community of practice.

Full textAbstract:
Les Sicydiinae amphidromes constituent une part importante des peuplements piscicoles insulaires de la région Indo-Pacifique et sont vulnérables à de nombreuses pressions anthropiques (i.e. pêcherie, dégradation et fragmentation des habitats). La reproduction a lieu en eau douce, puis les jeunes dévalent en mer où ils débutent leur croissance pendant quelques mois avant de coloniser les rivières. L’objectif est d’acquérir des connaissances sur les traits de vie de S. lagocephalus (cosmopolite) et de C. acutipinnis (endémique). Les travaux de terrain démontrent que le choix de l’habitat quotidien est fortement lié aux interactions sociales, alors que l’habitat de fraie montre une forte sélection pour des conditions morphodynamiques favorisant l’oxygénation des oeufs. Les mâles sélectionnent des sites de ponte et gardent les oeufs. L’étude expérimentale de la survie en eau douce confirme que tous les embryons libres possèdent la capacité à rejoindre la mer. L’analyse des traits de vie marins à partir des otolithes des post-larves révèle des variations saisonnières d’âge et de taille au recrutement, en lien avec la croissance et la température marine. L’examen histologique des ovaires permet de décrire les variations spatiales et temporelles de l’activité de reproduction chez les femelles en rivière et de déterminer la fécondité et la taille de première reproduction. Les variations inter et intra-spécifiques des traits de vie sontcomparées en lien avec la répartition géographique des deux espèces. Ces travaux permettent d’identifier des perspectives concrètes dans le domaine de la gestion et de la conservation sur la base des caractéristiques de la stratégie amphidromeAmphidromous Sicydiinae are particularly widespread among fish freshwater assemblages of the Indo-Pacific region and are vulnerable to anthropogenic pressures (i.e. fishery, degradation and fragmentation of habitats). Spawning and hatching happen in freshwater, then offspring drift downstream to the sea where they begin their growth for a few months before recruiting in the rivers. This study aims at acquire knowledge about life traits of S. lagocephalus (cosmopolite) and C. acutipinnis (endemic). Field sampling shows that the usual habitat choice is related to social interactions, whereasspawning habitat shows a strong selection for morphodynamic conditions which favor eggs oxygenation. Males select spawning sites and care for the eggs. The experimental study of freshwater survival confirms that free embryos survival and swimming capacities are enough to drift to the ocean. Marine life history analysis, based on postlarvae otoliths examination, reveals a seasonal variation of both age and size-atrecruitment related to the larval growth rate and the sea temperature. Histological examination of ovaries is used to describe the spatial and temporal variation of reproductive activity of mature females in the rivers, and to determine fecundity and size at first reproduction. Inter and intra-specific variations of life history traits are compared in relation to the respective geographical distribution of both species. This study identifies concrete prospects for management and conservation based on the features of amphidromous life history strategy

A fala de indivíduos com mordida cruzada anteroposterior e fissura labiopalatina reparada, antes e após a cirurgia ortognática, foi investigada quanto à: alteração do ponto articulatório (presença e tipo) dos diferentes grupos de fonemas; porcentagem e severidade do comprometimento; e associação com os aspectos estrutural, motor e sensorial. Avaliou-se 20 jovens, antes e 13 após a cirurgia, analisando: a fala (após 5 juízas verificarem as alterações do ponto articulatório) obtendo a porcentagem de consoantes corretas (PCC); a sensibilidade (estesiômetro Semmes-Weinstein - SORRI) e mobilidade (escores de 6 a 18) de lábios e língua; e a audição (limiar do SRT e perda auditiva nas freqüências baixas, médias e altas). Antes da cirurgia, a mediana da PCC (n=20) era 23% (15% em palatais), com comprometimento severo na maioria, passando para 69% (n=13) após a cirurgia (31% em palatais), havendo melhora na fala (p=0,001, N=13), com redução da severidade do comprometimento (p=0,002). Quanto maior o trespasse horizontal negativo antes da cirurgia, menor a PCC (p=0,019) e menor a porcentagem de melhora após a cirurgia (p=0,002). Os indivíduos avaliados apresentaram, antes da cirurgia: comprometimento severo da fala, com alteração do ponto articulatório especialmente dos fonemas labiodentais, linguodentais, e alveolares (principalmente ponto bilabial, interdental e ceceio); após a cirurgia verificou-se modificação significante na porcentagem e severidade do comprometimento da fala, evidenciada nos linguodentais, alveolares e labiodentais e rara variação no tipo de alteração; houve associação entre o aspecto estrutural e a PCC pré-cirúrgica, e entre o aspecto estrutural e o aumento pós-cirúrgico da PCC.The speech of individuals with anteroposterior crossbite and repaired cleft lip and palate, before and after orthognathic surgery, was evaluated as to alteration in the articulation point (presence and type) of the different groups of phonemes; percentage and severity of the disorder; and association with structural, motor and sensorial aspects. Twenty young individuals were evaluated before and 13 after surgery, for analysis of: speech (after 5 examiners analyzed alterations in the articulation point) for achievement of the percentage of correct consonants (PCC); sensitivity (esthesiometer Semmes-Weinstein - SORRI) and mobility (scores from 6 to 18) of the lips and tongue; and hearing (Speech Reception Threshold) and hearing loss at low, medium and high frequencies). Before surgery, the median of the PCC (n=20) was 23% (15% in palatal), with severe disorder in most, changing to 69% (n=13) after surgery (31% in palatal), with an improvement in speech (p=0.001, n=13) and reduction in the severity of disorder (p=0.002). The greater the negative overjet before surgery, the lower was the PCC (p=0.019) and the lower was the percentage of improvement after surgery (p=0.002). Before surgery, the evaluated subjects presented severe speech impairment with alterations in the articulation point, especially of labiodental, dental and alveolar phonemes (especially bilabial point and interdental and lisp); after surgery, there was significant improvement in the percentage and severity of speech impairment, evidenced in dental, alveolar and labiodental phonemes, with rare variation in the type of alteration; there was association between the structural aspect and the preoperative PCC, and between the structural aspect and the postoperative increase in the PCC.

Objetivo:A fissura labiopalatina acomete várias estruturas orofaciais e portanto, faz-se necessário a aplicação de um exame específico do sistema estomatognático. O objetivo deste estudo foi elaborar um protocolo de avaliação miofuncional orofacial para indivíduos com fissura labiopalatina e realizar a validação do conteúdo. Método: Após a aprovação do Comitê de Ética em Pesquisa, elaborou-se um protocolo de avaliação miofuncional orofacial, que contempla os aspectos estruturais e funcionais do sistema estomatognático. Esse protocolo foi revisado por dois fonoaudiólogos experientes na avaliação de pacientes com fissura la biopalatina e realizadas adequações necessárias. Em seguida, obteve-se imagens, necessárias à realização do exame miofuncional orofacial de 75 indivíduos com fissura labiopalatina, de ambos os sexos e diferentes fases da vida (infância, adolescência e adulta), que não apresentavam síndrome ou outras malformações associadas. As imagens foram armazenadas em um computador e transferidas para um dispositivo móvel para que três fonoaudiólogos experientes nesse tipo de avaliação as analisassem conforme o protocolo proposto. A concordância entre os fonoaudiólogos foi verificada pelo teste Kappa e a validação do conteúdo pela aplicação do Índice de Validação do Conteúdo. Resultados: O instrumento foi elaborado em 14 aspectos, 10 de domínios estruturais e 4 funcionais, composto pela descrição dos subitens correspondentes. A média geral do protocolo foi de 100% de concordância na validação do seu conteúdo. Para a aplicabilidade do protocolo, verificou-se que a porcentagem de concordância interexaminadores mostrou porcentagem acima da média para os aspectos das bochechas (53% a 65%), tonsilas palatinas (80% a 96%), oclusão (60% a 100%), palato duro (55% a 76%), úvula (75% a 85%), teste do espelho (76% a 100%), fala (57% a 99%) e voz (83% a99%), pouco menor que a média para os dentes (33% a 97%), véu palatino (40% a 100%), faringe (41% a 64%), língua (44% a 83%), lábios (45% a 93%) e respiração (48% a 65%). Houve concordância substancial intraexaminador para o aspecto da respiração e quase perfeita para os demais aspectos. Conclusão: O protocolo foi construído e validado para a fissura labiopalatina, visando abranger todos os aspectos estruturais e funcionais acometidos por ela. Considerou-se a validade de conteúdo do instrumento deste estudo uma medida válida e precisa para os 14 itens avaliados, assim como os seus subitens, tanto na opinião de especialistas, quanto nos resultados obtidos em sua aplicação.Objective: The cleft lip and palate affects many orofacial structures, thus, the application of a specific examination of the stomatognathic system is necessary. The aim of this study was to create a myofunctional assessment protocol and to validate its content. Method: After the approval of the Ethical Committee in Research, a myofunctional assessment protocol was created comprising the structural and functional aspects of the stomatognathic system. This protocol was reviewed by two experienced speech-language thera pists and the required changes were performed. Following, the images for performing the orofacial myofunctional examination were obtained from 75 cleft lip and palate individuals, both genders, at different ages (children, teenagers and adults), without syndromes or other associated malformations. The images were stored in computer memory and transferred to a mobile device so that three speech-language therapists experienced in this assessment type analyzed them according to the proposed protocol. Inter-examiners agreement was verified by Kappa test and the validation of the protocol content by Content Validity Index. Results: The protocol was created and comprised 14 spects: 10 of structural and 4 of functional domains, composed by the description of the corresponding sub-items. The general mean of the protocol was of 100% of agreement in the validation of its content. In the protocol applicability, the percentage of inter -examiners agreement was above the mean for the aspects of cheeks (53% to65%), palatine tonsils (80% to 96%), occlusion (60% to 100%), hard palate (55% to 76%), uvula (75% to 85%), mirror test (76% to 100%), speech (57% to 99%) and voice (83% to 99%); little below the mean for the teeth (33% to 97%), velum (40% to 100%), pharynx (41% to 64%), tongue (44% to 83%), lips (45% to 93%) and reathing (48% to 65%). There was substantial agreement for breathing and almost perfect agreement for the other aspects. Conclusion: The protocol of orofacial myofunctional assessment specific for cleft lip and palate individuals was created and validated comprising all the structural and functional aspects impaired by this malformation. The content validity of this protocol was considered as a valid and accurate measurement for the 14 items evaluated and their sub-items, considering both the opinion of the experts and the results obtained in its application.

Full textAbstract:
La situation géodynamique de la Basse-Terre de Guadeloupe sur l’arc des Petites Antilles marquée par un volcanisme actif, est favorable au développement de la géothermie haute-enthalpie. Ainsi, en 1986, la centrale géothermique de Bouillante a été mise en production. Le programme Geotref (plate-forme pluridisciplinaire d’innovation et de démonstration pour l’exploration et le développement de la GEOThermie haute énergie dans les REservoirs Fracturés), financé par l’ADEME dans le cadre des Investissements d’Avenir, vise à explorer les possibilités de développer la géothermie au Sud de Bouillante, dans le secteur de Vieux-Habitants. Cependant, en raison de la présence de nombreuses coulées volcano-clastiques récentes, peu d’indices de surface de la présence d’un réservoir géothermique y sont visibles. L’île de Terre-de-Haut (archipel des Saintes) est considérée comme un analogue exhumé du système géothermique de Bouillante (Verati et al., 2016) et représente une zone clef pour étudier les paléo-altérations hydrothermales. Afin de déterminer les critères pétrographiques et minéralogiques des paléo-altérations hydrothermales et aussi caractériser les paléo-fluides en termes de composition et de température, cette étude propose de coupler les approches pétrographique, minéralogique, géochimique et géothermométrique menées par diffraction des rayons X, analyses microsondes, thermométrie sur chlorite et étude d’inclusions fluides dans des quartz néoformés. Les minéraux argileux présentent une distribution concentrique à l’échelle de l’île (chlorite au centre, smectite en périphérie, et illite entre les deux). La similitude de cette zonation avec celle observée en profondeur à Bouillante, permet d’interpréter cela comme une section horizontale affichant un gradient de température latéral. La géothermométrie sur chlorite est basée sur un modèle développé pour les contextes de basse température et basse pression (T<350°C et P < 4 kbar ; Bourdelle et al., 2013). Elle a été appliquée sur les chlorites identifiées à Terre-de-Haut ainsi que sur les chlorites de Bouillante grâce aux analyses chimiques de la littérature (Mas et al., 2006). Les résultats montrent une grande différence des températures estimées entre les chlorites de Terre-de-Haut (environ 120°C) et celles de Bouillante (environ 230°C, en accord avec les températures mesurées dans les forages de Bouillantes ; Mas et al., 2006). La microthermométrie des inclusions fluides sur les quartz ont montré deux épisodes de croissances enregistrés dans le cœur du cristal et sa périphérie. Ces quartz ont cristallisé à partir de fluides de basse salinité (≤ 2% NaCl, typique des eaux météoriques) avec une température minimum de piégeage de 250-280°C dans le cœur et de moins de 70°C dans les zones de croissance externes. Ces deux évènements peuvent être interprétés comme un enregistrement du refroidissement des fluides durant l’évolution du système géothermal. Les inclusions fluides d’un second échantillon de quartz, indiquent un épisode de circulation peu profond à CO2 et basse température (≤70°C). Cette étude montre que la zonation des minéraux argileux à l’affleurement à Terre-de-Haut est similaire à celle observée dans les forages du système actif de Bouillante. Cependant, les températures estimées pour la formation de certains minéraux néoformés (chlorite notamment) indiquent que certains épisodes d’altérations se produisent à des températures plus faibles que la circulation de fluide dans le système géothermique actif de Bouillante, et pourraient représenter des témoins de la fin de vie du système géothermal de Terre-de-Haut.Les résultats de cette thèse montrent que l’étude des minéraux argileux et les données de géothermométrie sur les minéraux néoformés (chlorite et quartz), permettent par conséquent d’apporter de nouvelles contraintes dans la caractérisation du paléo-système de Terre-de-Haut et son évolution, en particulier sur la fin de vie du système géothermalDue to its geodynamic location on the Lesser Antilles arc, Basse-Terre of Guadeloupe displays an active volcanism which is favorable to the development of geothermal energy associated to power generation. Thus, thirty years ago, the Bouillante geothermal field was brought into production and now produces 15 MWe (Bouchot et al., 2010).The Geotref program (a multidisciplinary platform for innovation and demonstration activities for the exploration and development of high geothermal energy in fractured reservoirs) funded by ADEME in the frame of “Les Investissements d’Avenir” program, aims to investigate the high enthalpy geothermal potential in the Vieux-Habitants area, located south of Bouillante. However, because of recent volcano-clastic deposits, surfaces showing the presence of a geothermal reservoir are rare. Terre-de-Haut island (Les Saintes archipelago) is considered as an exhumed analog of the deep geothermal system of Bouillante (Verati et al., 2016) which represents a key area to study the paleo-hydrothermal alterations. To characterize the paleo-hydrothermal alterations in terms of composition and temperature, and to determine the mineralogical and petrographic features of the paleo-hydrothermal alterations, we propose to couple petrographic, crystallographic, geochemical and geothermometric approaches, i.e. X-ray diffraction (XRD), microprobe analysis (EMPA), chlorite thermometry and in-quartz fluid inclusion study (FI) on selected samples. A link is also established with the petrophysical properties of the altered.The clay minerals display a specific concentric distribution at the scale of the island, with chlorite crystallization in the core, smectite in the surroundings, and illite in an intermediate halo. Considering the data obtained in boreholes in Bouillante, which show that illite and chlorite are in the deeper parts, chlorite being located in the heart of the geothermal reservoir (Bouchot et al., 2010), the clay distribution allows to identify the temperature profile. Hence, thanks to the exhumation, we are looking to a horizontal section through the paleo-system of Terre-de-Haut, where we observe a lateral temperature gradient.Chlorite geothermometry, based on a model specifically developed for low temperature contexts (T < 350°C) and pressures below 4 kbar (Bourdelle et al., 2013), has been applied on chlorites from both Terre-de-Haut paleo-system and from the active geothermal system of Bouillante. The results show a strong difference between the temperature estimates for chlorite formation on Terre-de-Haut (around 120°C) and for Bouillante (around 230°C, in agreement with the temperature measured in boreholes in Bouillante; Mas et al., 2006).Fluid inclusions microthermometry on quartz show two growth stages recorded in the crystal core and clear overgrowths. Data indicate very low salinity (≤ 2% NaCl), and a minimum trapping temperature of around 250-280°C in inclusions located in the core, and around 70°C or less in the outer growth zones. These two events can be interpreted as a record of the fluid cooling during system evolution. Moreover, fluid inclusions from a second quartz sample indicate a shallow CO2 paleo-circulation episode.This study shows that the clay mineral zonation cropping out in Terre-de-Haut is similar to that found by drilling in the active system of Bouillante. However, the temperatures of formation of some newly formed minerals (especially chlorite) indicate that some alteration episodes occurs at lower temperature than the fluid circulation occurring in Bouillante’s active geothermal system and could represent the end of life of the Terre-de-Haut geothermal system.Hence, these results show that clay minerals study and geothermometry of newly formed minerals (chlorite and quartz) are key steps to provide new thermal constrains on the paleo-geothermal reservoir of Terre-de-Haut and its evolution, particularly the end of life of the geothermal system

Haïti est située sur la partie occidentale de l'île d'Hispaniola, qu'il partage avec la République dominicaine à l'est. Haïti est située en limite septentrionale des Caraïbes, où le mouvement relatif entre les plaques Caraïbes et Amérique du Nord est accommodé par un système complexe de microplaques de failles et de blocs tectoniques. Deux failles décrochantes sismogènes liées à ce système se trouvent en Haïti ; la zone de faille d'Enriquillo – Plantain Garden (EGPFZ) sur la partie sud d'Haïti et la zone de faille Septentrionale (SFZ) au large de la partie nord d'Haïti, tandis que la chaîne trans-haïtienne, composée de chevauchements d’unités tectoniques haïtiennes se propage vers le sud-ouest. La géologie et le contexte géodynamique d'Haïti font l'objet d'un regain d'intérêt scientifique à cause du séisme très destructeur de Mw 7.0, survenu le 12 janvier 2010, qui s’est produit au sud d'Haïti à Leogâne, près de la capitale Port-au-Prince. Cette étude, qui est une collaboration entre Sorbonne Université, IFP Energies nouvelles (IFPEn), l’Université d’Etat d’Haïti (UEH), URGéo, et le Bureau des Mines et de l’Energie d’Haïti (BME), participe à l'accroissement des connaissances géologiques de la zone méridionale d'Haïti. Elle comporte trois objectifs principaux ; 1) identifier le nombre et la chronologie des phases de déformation de la péninsule sud d'Haïti, leur impact régional, leur style structural, et l'évolution des paléo-contraintes, 2) contraindre l'histoire de la déformation de la zone frontale de la chaîne trans-haïtienne (la chaîne des Matheux), et (3) caractériser l'interaction entre les fluides et la déformation en examinant la circulation des paléo‐fluides associée à la déformation dans les deux régions. Pour atteindre ces objectifs, cette étude intègre des données géologiques et des observations à terre sur Haïti acquises lors de deux campagnes de terrain en 2015 et 2017. Les données stratigraphiques et structurales sont combinées avec l’étude des images satellitaires pour établir quatre cartes géologiques à petite échelle (~1:50.000) et des coupes transversales, qui permettent de mieux comprendre et de contraindre la déformation dans la région. Des échantillons de roches et de veines sont analysés à l'aide d'une série de techniques analytiques, incluant la microscopie optique, la cathodoluminescence, la micro‐thermométrie des inclusions fluides et la spectroscopie Raman sur ces inclusions, la diffraction des rayons X, la géochimie des isotopes stables, et la géochimie sur roche totale. L'ensemble des analyses est intégré afin de documenter et comprendre la circulation des paléo‐fluides. Les résultats de cette étude indiquent que la Péninsule du Sud s’est développée sur une large zone d’inversion bordée par des chevauchements impliquant le socle, tandis que la déformation dans la Chaîne des Matheux est principalement à l’origine d'une tectonique contrôlée par des niveaux de décollement peu profonds, suivie tardivement par des inversions de socle. L'histoire de déformation de la Péninsule du Sud est polyphasée et caractérisée par trois phases tectoniques majeures; 1) Compression et soulèvement durant le Maastrichtien et le Paléocène inférieur, 2) compression et soulèvement du Miocène inférieur qui affectaient principalement la partie sud‐ ouest de la Péninsule du Sud, et 3) déformation transpressive du Miocène supérieur à l’actuel. Cette dernière phase est caractérisée par une concentration progressive d'activité décrochante le long de l'EPGFZ, qui enregistre un maximum de 15 km de déplacement sénestre depuis la fin du Messinien [...]Haiti is located on the western part of the island of Hispaniola, shared with the Dominican Republic in the east. Haiti is situated within the northern Caribbean plate boundary region where relative motion between the Caribbean and North American plates is accommodated by a complex system of fault-bounded microplates and tectonic blocks. Two seismogenic strike-slip faults related to this system are found in Haiti; the Enriquillo – Plantain Garden Fault Zone (EGPFZ) onshore southern Haiti, and the Septentrional Fault Zone (SFZ) offshore northern Haiti, with the southwest-verging, forward-propagating Haitian Fold-and-Thrust Belt situated in between them. The geology and geodynamic setting of Haiti became the focus of increased scientific interest following the January 12th 2010 Mw 7.0 Leogâne earthquake, which struck southern Haiti close to its capital Port-au-Prince. This study, which is a collaboration between Sorbonne Université, IFP Energies nouvelles (IFPEn), Université d’Etat d’Haïti (UEH), URGéo, and Bureau des Mines et de l’Energie d’Haïti (BME), is dedicated to increase our knowledge of the onshore geology of southern Haiti. There are three main objectives to this study; 1) identify the number and timing of deformation phases on the Southern Peninsula of Haiti, their regional impact, and the associated structural style of deformation and paleo-stress evolution, 2) constrain the deformation history of the southernmost onshore part of the Haitian Fold-and-Thrust Belt (the Chaîne des Matheux), the structural style of deformation and the associated paleo-stress evolution, and 3) characterize the interaction between fluids and deformation by examining the paleo-fluid circulation related to deformation in both regions. To fulfill these objectives this study integrates geological data and observations onshore Haiti from field campaigns in 2015 and 2017. Stratigraphic and structural data are combined with satellite imagery and digital elevation models to create four small-scale (~1:50.000) geological maps and associated cross sections. These are used to better understand and constraining the style of deformation in the region. Samples of host rocks and veins from fault zones and fractures are analyzed using a suite of analytical techniques, which include optical and cathodoluminescence microscopy, fluid inclusion microthermometry and Raman spectroscopy on fluid inclusions, x-ray diffraction, stable oxygen and carbon isotope geochemistry, and whole-rock geochemistry, all of which are integrated to constrain the paleofluid circulation. The results of this study indicate that 1) the Southern Peninsula evolved by basement-involved inversion, thrusting, and strike-slip, while 2) the style of deformation in the Chaîne des Matheux is predominantly thin-skinned controlled by shallow dipping decollement levels, although a component of thick-skinned basement-involved deformation is probable. The polyphase deformation history of the Southern Peninsula is characterized by three major tectonic events; 1) Deformation and uplift during the Maastrichtian and early Paleocene, 2) early Miocene compression and uplift that mainly affected the southwestern part of the Southern Peninsula, and 3) transpressive deformation from the late Miocene to recent. This last phase is characterized by a progressive focus of strike-slip activity along the EPGFZ, which accommodated a maximum of 15 km of left-lateral displacement since the late Messinian [...]

Dans le cadre de cette thèse, on s'intéresse à la dynamique de quelques fluides complexes. D'une part on étudie la dynamique des cristaux liquides nématiques, en utilisant les modèles proposés par Ericksen et Leslie, Beris et Edwards, Qian et Sheng. D'autre part, on analyse un fluide complexe dont la dynamique dépend de la température et qui est modélisée par le système de Boussinesq. Les cristaux liquides sont des matériaux avec une phase de la matière intermédiaire entre les liquides et les solides qui sont des phases plus connues. Dans cette thèse, on s'intéresse à l'étude du problème de Cauchy associé à chaque système modélisant leurs hydrodynamiques. Tout d'abord on obtient des résultats d'existence et d'unicité de solutions faibles ou classiques, solutions qui sont globales en temps. Ensuite, on analyse la propagation de la régularité des données initiales pour ces solutions. Le cadre fonctionnel adopté pour les données initiales est celui des espaces de Besov homogènes, généralisant des classes d'espaces mieux connues : les espaces de Soboloev homogènes et les espaces de Hölder. Le système Ericksen-Leslie est considéré dans la version simplifiée proposée par F. Lin et C. Liu, version qui préserve les principales difficultés du système initial. On étudie ce problème en dimension supérieure ou égale à deux. On considère le système dans le cas inhomogène, c'est-à dire avec une densité variable. De plus, on s'intéresse au cas d'une densité de faible régularité qui est autorisée à présenter des discontinuités. Donc, le résultat que l'on démontre peut être mis en relation avec la dynamique des mélanges de nématiques non miscibles. On démontre l'existence globale en temps de solutions faibles de régularité invariante par changement d'échelle, en supposant une condition de petitesse sur les données initiales dans des espaces de Besov critiques. On démontre aussi l'unicité de ces solutions si de plus on suppose une condition supplémentaire de régularité pour les données initiales. Le système Beris-Edwards est analysé dans le cas bidimensionnel. On obtient l'existence et l'unicité de solutions faibles globales en temps, lorsque les données initiales sont dans des espaces de Sobolev spécifiques (sans condition de petitesse). Le niveau de régularité de ces espaces fonctionnels est adapté pour bien définir les solutions faibles. L'unicité est une question délicate et demande une estimation doublement logarithmique pour une norme sur la différence entre deux solutions dans un espace de Banach convenable. Le lemme d'Osgood permet alors de conclure à l'unicité de la solution. On obtient également un résultat de propagation de régularité d'indice positif. Afin de prendre en compte l'inertie des molécules, on considère aussi le modèle proposé par Qian et Sheng, et on étudie le cas de la dimension supérieure ou égale à deux. Ce système montre une caractéristique structurale spécifique, plus précisément la présence d'un terme inertiel, ce qui génère des difficultés significatives. On démontre l'existence d'une fonctionnelle de Lyapunov et l'existence et l'unicité de solutions classiques globales en temps, en considérant des données initiales petites. Enfin, on analyse le système de Boussinesq et on montre l'existence et l'unicité de solutions globales en temps. On considère la viscosité en fonction de la température en supposant simplement que la température initiale soit bornée, tandis que la vitesse initiale est dans des espaces de Besov avec indice de régularité critique. Les données initiales ont une composante verticale grande et satisfont à une condition de petitesse spécifique sur les composantes horizontales: elles doivent être exponentiellement petites par rapport à la composante verticaleThe present thesis is devoted to the dynamics of specific complex fluids. On the one hand we studythe dynamics of the so-called nematic liquid crystals, through the models proposed by Ericksen and Leslie, Beris and Edwards, Qian and Sheng.On the other hand we analyze the dynamics of a temperature-dependent complex fluid, whose dynamics is governed by the Boussinesq system.Nematic liquid crystals are materials exhibiting a state of matter between an ordinary fluid and a solid. In this thesis we are interested in studying the Cauchy problem associated to eachsystem modelling their hydrodynamics. At first, we establish some well-posedness results, such asexistence and uniqueness of global-in-time weak or classical solutions. Moreover we also analyzesome dynamical behaviours of these solutions, such as propagations of both higher and lowerregularities.The general framework for the initial data is that of Besov spaces, which extend the most widelyknown classes of Sobolev and Hölder spaces.The Ericksen-Leslie system is studied in a simplified form proposed by F. Lin and C. Liu,which retains the main difficulties of the original one. We consider both a two-dimensional and athree-dimensional space-domain. We assume the density to be no constant, i.e. the inhomogeneouscase, moreover we allow it to present discontinuities along an interface so that we can describe amixture of liquid crystal materials with different densities. We prove the existence of global-in-timeweak solutions under smallness conditions on the initial data in critical homogeneous Besov spaces.These solutions are invariant under the scaling behaviour of the system. We also show that theuniqueness holds under a tiny extra-regularity for the initial data.The Beris-Edwards system is analyzed in a two-dimensional space-domain. We achieve existenceand uniqueness of global-in-time weak solutions when the initial data belongs to specific Sobolevspaces (without any smallness condition). The regularity of these functional spaces is suitable inorder to well define a weak solution. We achieve the uniqueness result through a specific analysis,controlling the norm of the difference between to weak solutions and performing a delicate doublelogarithmicestimate. Then, the uniqueness holds thanks to the Osgood lemma. We also achieve aresult about regularity propagation.The Qian-Sheng model is analyzed in a space-domain with dimension greater or equal than two.In this case, we emphasize some important characteristics of the system, especially the presence ofan inertial term, which generates significant difficulties. We perform the existence of a Lyapunovfunctional and the existence and uniqueness of classical solutions under a smallness condition forthe initial data.Finally we deal with the well-posedness of the Boussinesq system. We prove the existence ofglobal-in-time weak solutions when the space-domain has a dimension greater or equal than two.We deal with the case of a viscosity dependent on the temperature. The initial temperature is justsupposed to be bounded, while the initial velocity belongs to some critical Besov Space. The initialdata have a large vertical component while the horizontal components fulfil a specific smallnessconditions: they are exponentially smaller than the vertical component

Objetivo: Investigar a função auditiva, periférica e central, em pacientes com o diagnóstico da síndrome G/BBB, quanto à ocorrência ou não de perda auditiva e, a condução nervosa auditiva periférica e central, em nível do tronco encefálico. Modelo: Análise prospectiva descrevendo os achados audiológicos em indivíduos com a síndrome G/BBB. Local de Execução: Setor de Genética, HRAC-USP. Participantes: 14 pacientes na faixa etária de 7 a 34 anos, do gênero masculino. Variáveis: Limiares audiométricos em decibels nas frequências de 0,25 a 8 kHz nas duas orelhas, tipo de curva timpanométrica nas duas orelhas, latências absolutas das ondas I, III e V; latências interpicos I-V, III-V e I-III e diferença interaural da onda V do PEATE, em milissegundos, para cada orelha. Resultados: Limiares audiométricos normais em 12 (66,7%) pacientes da amostra, e 2 (33,3%) com perda auditiva, sendo 1 do tipo condutiva e 1 neurossensorial. Quanto aos resultados do PEATE, foram encontrados: latências absolutas da onda I dentro dos padrões de normalidade em todos os pacientes, aumento das latências absolutas da onda III e V em 2 e 6 pacientes respectivamente; e as latências interpicos I-III, III-V e I-V se apresentaram aumentadas em 4, 3 e 8 pacientes respectivamente. Conclusões: Frente aos resultados obtidos podemos concluir que pacientes com a síndrome G/BBB podem apresentar perdas auditivas periféricas, condutivas e neurossensoriais, entretanto, não há subsídios para afirmar que as mesmas são em decorrência da síndrome ou da associação com a fissura de palato. Há evidências de comprometimento das vias auditivas centrais em nível do tronco encefálico, embora as alterações estruturais do SNC relatadas nesta síndrome não estejam relacionadas diretamente com as vias auditivas. Estudos com enfoque no perfil audiológico desta população com exames de imagem são necessários para maior clareza dos achados clínicos.Objective: To investigate the peripheral and central auditory function in patients with G/BBB syndrome and the occurrence of hearing loss in these patients. Model: Prospective study describing the audiological findings in subjects with G/BBB syndrome. Setting: Genetics Department, HRAC-USP. Participants: 14 male patients aged from 7 to 34 years. Variables: Audiometric thresholds in decibels at frequencies of 0.25 to 8 KHz in both ears, tympanometric curve in both ears, absolute latencies of waves I, III and V, interpeak latencies I-V, III-V and I-III and wave V interaural difference of ABR, in milliseconds, for each ear. Results: Normal audiometric thresholds were found in 12 (66.7%) patients, 2 (33.3%) had hearing loss, one type conductive and one sensorioneural. ABR results were: absolute latencies of wave I within normal limits in all patients, an increase of absolute latencies of wave III and V in 2 and 6 patients respectively, and interpeak latencies I-III, IV and V were increased in 4, 3 and 8 patients respectively. Conclusions: Patients with G/BBB syndrome may have peripheral conductive or sensorineural hearing loss; however, there are no subsidies to attribute the etiology to the syndrome itself or to the presence of cleft palate, which was found in all patients. There is evidence of central auditory pathways involvement in the brainstem level, although the structural CNS abnormalities reported in this syndrome are not directly related to the auditory pathways evaluated. Studies focusing on the audiological profile of this population with imaging studies are recommended.
