Resumen

Complex design and morphologic problems, consisting of multiple parameters, can be described, modelled and indexed using a meta-morphological technique presented here. All design and morphologic variables can be mapped in Euclidean n-dimensional space, where n is the number of variables. This meta-space contains all the possible solutions to the problem and each point in this solution n-space is a candidate solution. The desired solution, represented by a specific point in this space and coded (addressed) by its n-dimension Cartesian co-ordinates, is ranked by the hyper-distance of this point from the origin. The hyper-distance itself provides a design index (or hyper-index) of the solution and can be determined by the known hyper-Pythagorean theorem. The procedure is recursive and applies to complex design problems which are hierarchical and composed of problem-within-problem-within-problems. Here the parameters are composed of subparameters, and the solutions are correspondingly mapped in a recursive, fractal n-cube composed of sub-cubes composed of sub-sub-cubes. The total composite index is determined by the recursive application of the hyper-Pythagorean theorem and represents a quantification of the morphological complexity of the design. The model is independent of the design problem, and has attractive possibilities for application in computer-aided design environments. The application is shown with the hypothetical selection of a space frame from a number of alternatives.

Resumen

Background: Preoperative assessment by calculating the morphological cortical Index (MCI), canal-calcar ratio (CCR), canal flare index (CFI) and canal bone ratio (CBR) will facilitate appropriate surgical planning for total hip arthroplasty. Since no data on indices and ratios of proximal femur in Punjab is available the study was planned to record the same from radiographs of normal adult population. Study design: Cross-sectional population study Methods: MCI, CCR, CFI and CBR were calculated from measurements on anteroposterior radiographs of the proximal femur from 116 male and 96 female subjects with a mean age of 46 years. Results: Morphologic cortical index, canal calcar ratio and canal flare index did not have any statistically significant difference between the two sexes. Canal bone ratio showed a highly significant difference when the male and female group were compared (p = 0.0042). Conclusion: The study has provided baseline data on morphologic cortical index, canal calcar ratio, canal flare index and canal bone ratio of proximal femur in Punjab which may be helpful in surgical planning for total hip arthroplasty and further research in the area. Keywords: Morphological Cortical Index (MCI), Canal-calcar Ratio (CCR), Canal Flare Index (CFI), Canal Bone Ratio (CBR), proximal femur, morphometry, total hip arthroplasty (THA)

Resumen

OBJECTIVEPrevious studies have shown a relation between growth and rupture of intracranial aneurysms. Additionally, several morphological characteristics are frequently measured to estimate rupture risk. Little is known about how the rupture risk is associated with morphological characteristic changes during growth. The aim of this study was to provide insights into how morphological characteristics, associated with rupture, change during an aneurysm’s growth.METHODSThe authors retrospectively identified patients with longitudinal MRA images of unruptured growing aneurysms. The MRA images had an in-plane resolution of 0.2–0.5 mm and a slice thickness of 0.2–0.75 mm. Therefore, growth was defined as an increase of at least 0.5 mm in two directions or 1 mm in one direction. Using the MRA images, the authors semiautomatically segmented the aneurysm and the perianeurysmal vasculature. Twelve morphological characteristics were automatically measured. These characteristics were related to size (diameter, height, width, neck diameter, volume, surface area, aspect ratio, height-width ratio, and bottleneck factor) and shape (ellipticity index, nonsphericity index, and undulation index) of the aneurysm. Morphological characteristics before and after growth were compared using the Wilcoxon signed-rank test.RESULTSThe authors included 31 patients with 38 growing aneurysms. The aneurysms’ growth was detected after a mean of 218 weeks (range 23–567 weeks). A significant increase was seen in all size-related characteristics, and the bottleneck factor also significantly increased (from a median of 1.00 [IQR 0.85–1.04] to 1.03 [IQR 0.93–1.18]), while the ellipticity index decreased (from a median of 0.26 [IQR 0.25–0.28] to 0.25 [IQR 0.24–0.26]). The changes in size ratios and shape indices varied largely among patients. Larger aneurysms more often showed an increase in shape ratios.CONCLUSIONSAlthough aneurysm growth, size-related characteristics, bottleneck factor, and ellipticity index changed significantly during growth, most size ratios and shape indices showed inconsistent changes among aneurysms. This suggests that, for an accurate rupture prediction, morphological parameters need to be reassessed after growth.

Resumen

Background: Ovarian cancers ranks fifth in cancer death worldwide and in India it ranks third among the female genital tract malignancies. Objective of present study was to assess prospectively the efficacy of morphological indexing (MI) as a method to predict malignancy in sonographically confirmed ovarian tumors.Methods: A prospective study conducted in a tertiary care hospital in Tamil Nadu from September 2011 to August 2012. The risk of malignancy is preoperatively assessed in 136 patients with ovarian tumour using a morphological index based on tumour volume and wall structure. Each tumour was assigned a score of 0 to 10 based on increasing volume and morphologic complexity. The efficacy of the index was assessed by histopathological examination of the tumour.Results: The benign tumours had a mean MI score of 4.3 and malignant tumours had a mean of 8.3 which was statistically significant. Of the 54 tumours with MI <5, only 2 (3.7%) were malignant where else out of the remaining 82 tumours with MI >5, 54 (51.2%) were malignant. With MI >5 as a predictor of malignancy the present study had a Sensitivity-95.5%, Specificity-56.5%, Positive predictive value-51.2%, Negative predictive value-94%, and Accuracy-68%.Conclusions: Morphological index is a simple, valuable and inexpensive diagnostic tool to rule out malignancy in pre operative evaluations of ovarian tumors.

Resumen

This thesis deals with Swedish full text retrieval and the problem of morphological variation of query terms in thedocument database. The study is an information retrieval experiment with a test collection. While no Swedish testcollection was available, such a collection was constructed. It consists of a document database containing 161,336news articles, and 52 topics with four-graded (0, 1, 2, 3) relevance assessments. The effects of indexing strategy-query term combination on retrieval effectiveness were studied. Three of five testedmethods involved indexing strategies that used conflation, in the form of normalization. Further, two of these threecombinations used indexing strategies that employed compound splitting. Normalization and compound splittingwere performed by SWETWOL, a morphological analyzer for the Swedish language. A fourth combinationattempted to group related terms by right hand truncation of query terms. A search expert performed the truncation.The four combinations were compared to each other and to a baseline combination, where no attempt was made tocounteract the problem of morphological variation of query terms in the document database. Two situations were examined in the evaluation: the binary relevance situation and the multiple degree relevancesituation. With regard to the binary relevance situation, where the three (positive) relevance degrees (1, 2, 3) weremerged into one, and where precision was used as evaluation measure, the four alternative combinationsoutperformed the baseline. The best performing combination was the combination that used truncation. Thiscombination performed better than or equal to a median precision value for 41 of the 52 topics. One reason for therelatively good performance of the truncation combination was the capacity of its queries to retrieve different partsof speech. In the multiple degree relevance situation, where the three (positive) relevance degrees were retained, retrievaleffectiveness was taken to be the accumulated gain the user receives by examining the retrieval result up to givenpositions. The evaluation measure used was nDCG (normalized cumulated gain with discount). This measurecredits retrieval methods that (1) rank highly relevant documents higher than less relevant ones, and (2) rankrelevant (of any degree) documents high. With respect to (2), nDCG involves a discount component: a discount withregard to the relevance score of a relevant (of any degree) document is performed, and this discount is greater andgreater, the higher position the document has in the ranked list of retrieved documents. In the multiple degree relevance situation, the five combinations were evaluated under four different user scenarios,where each scenario simulated a certain user type. Again, the four alternative combinations outperformed thebaseline, for each user scenario. The truncation combination had the best performance under each user scenario.This outcome agreed with the performance result in the binary relevance situation. However, there were alsodifferences between the two relevance situations. For 25 percent of the topics and with regard to one of the four userscenarios, the set of best performing combinations in the binary relevance situation was disjunct from the set of bestperforming combinations in the multiple degree relevance situation. The user scenario in question was such thatalmost all importance was placed on highly relevant documents, and the discount was sharp. The main conclusion of the thesis is that normalization and right hand truncation (performed by a search expert)enhanced retrieval effectiveness in comparison to the baseline, irrespective of which of the two relevance situationswe consider. Further, the three indexing strategy-query term combinations based on normalization were almost asgood as the combination that involves truncation. This holds for both relevance situations.

Resumen

The EC directive REACH (EC1907/2006) sets, amongst others, the need for all the chemicals to be tested for their carcinogenic potential. In vitro assays can provide a fast and reliable tool for screening purposes. The Cell Transformation Assay (CTA) is one of the in vitro assays in the most advanced phase of the validation process and the only one able to evaluate both the genotoxic and the non-genotoxic potentials. The evaluation of results of the CTA is based on the scoring of transformed colonies (foci) by a trained expert on the basis of their morphological features. Levels of cell packing and multilayered growth, as well as fibroblastic shape of cells, criss-crossing and invasion of the surrounding monolayer features are evaluated for classification. While the decision making process is based on standard criteria, their interpretation is potentially biased, especially in borderline cases, due to a certain degree of subjectivism inherent in the evaluation of qualitative features. This aspect is critical towards the international validation of the CTA assay: subjectivity driven error might in fact result in under or over estimation of the carcinogenic potential of tested compounds. In this work, different approaches were used to develop an objective method to give decisional support to the operator in the classification procedure. Biological markers related to the transformation process (p53, cx43), and to a general cell stress (Hsp70) were analyzed. A novel technique for the in focus localization of biological markers of transformation was developed. RNA whole genome screening was used to set the conditions for future molecular characterization of foci-derived cell lines. A novel, Quantitative Index of Dissimilarity has been obtained by statistical descriptors capturing morphological features and employing an unsupervised image analysis approach, in order to help the operator in the decisional process of scoring the borderline cases.

Resumen

Several studies have been carryout to highlight the scientific community about the importance of coastal beach-dune system in coastal dynamics recognizing. Their ecological and environmental value is very important, they play a fundamental rule in coastal defense protecting hinterland from flooding with their raised morphology, contrasting the salt wedge’s intrusion with their water table and moreover they constitute an important reservoir of sand for beaches This aspect in the Emilia-Romagna region seems to be particularly important: many coastline features are characterized by emergency conditions because they are exposed more frequently and dangerously to phenomena of submersions for sea storm’s events and to a diffuse and intense marine erosion. Actually, along 130 km of the Emilia-Romagna coastline, 29 km are characterized by the presence of coastal dunes, of which, approximately 9,5 km belong to the province of Ferrara, approximately 18 km to Ravenna’s and remaining to the more to south coastal part of the region. In this paper the results of a regional research are presented trough the application of a methodological integrated approach (System’s Theory), that aims to analyze and to point out the evident morphoevolutionary state of crisis in which the Emilia Romagna dunes today are (2008). Another objective is to try to optimize the management’s policies of natural sedimentary resources, which are today very important for the new philosophical approaches to coastal problems. The final result is a tool able to supply indications about the priorities to front and the actions methodologies finalized to the safeguard and the defense of these delicate environmental subsystems. It becomes fundamental to have the correct perception of the phenomena in action and to quantify the “weight” that the several morphodynamic’s agents have in the coastal dune system’s evolution. The parameterization of such factors, the spatial analysis, the multi-scale and temporal analysis (from 2000 to today) helps us to identify the relations of mutual interaction between such parameters. Therefore, it’s possible to extract an Instability beach-Dune system Index (IDI) to establish the state of system’s instability, and a space-temporal variability allowing their possible future evolution forecasting. Among all the factors, the anthropic impact of the several tourist activities on the management of coastal spaces, in the Emilia Romagna region seems to be the most important: only for the province of Ferrara, for example, from 2000 to today, the areas lacking in vegetation developed on dunes, have increased of approximately 11%. The majority have become unvegetated ground knots (blowouts), full of recreational structures, or transformed in tourist’s beaches. Through the overlap of several classes of land cover distributions (change detection), it is possible to gain important indications on the dunes erosive trends: of the 9,5 km of the Ferrara’s dune’s coastal strip, nowadays approximately 4,2 km, is developed through an erosion escarpment with height greater than 1m. This demonstrates that the exposure to wave action is intense and frequent. In these cases the processes can reach to abrupt accelerations, till to assume speed and various intensities also from point to point for a same system; in a short time, the opening of crosses and the development of blowouts can put in crisis the whole dune’s system and expose the inlands to a risk. In 11 cases on 23, the front beach highlights an erosion trend and the width is less then 20m with the dune’s foot which is often constituted by temporary accumulation generated by landslides of the erosion walls. Therefore, this job has been integrated with a study on the wind’s “potentialities” to contribute to the maintenance and/or the development of dunes, by applying a conceptual model (Kadib, 1983; Bagnold, 1941) that allows to gain an annual potential sedimentary budget for each system, in relation to the medium climate and to the morphological and sedimentary characteristics of the system. Such aspect can supply important indications during all the steps of a coastal action, beginning from the planning and realization of sedimentary traps, till their positioning and direction. Moreover, the obtained results above all demonstrate as such methodological approach can represent a real, useful, regional scale instrument to all policies of coastal land management, to the research on new technical of actions or to program and optimize the resources.

Resumo: A expansão urbana vem formando aglomerados populacionais desordenados, o que causa problemas para a administração municipal. A fim de reduzir este tipo de problema, uma das maneiras de reorganizar o território é o policentrismo, conceito que vem sendo aplicado em grande parte da área urbana de diversos países como Estados Unidos, China e países da Europa. O policentrismo pode ser entendido como uma área urbana com pluralidade de centros urbanos. Há duas abordagens para identificar possíveis centralidades: a morfológica e a funcional. Além disso, não foi encontrado quaisquer resultados de trabalhos científicos que tenham utilizado a variável inclinação do relevo nas análises de identificação de centralidades urbanas. Dessa maneira, a variável declividade pode ser um fator impactante na determinação de uma centralidade ou núcleo urbano para localidades brasileiras e que tenha característica similares da área de estudo. O objetivo desse trabalho propõe um estudo para a identificação de centralidades ou a possibilidade de identificar novos núcleos urbanos, por meio da avaliação da morfologia do terreno na formação de subcentros no município de Barra do Piraí no Estado do Rio de Janeiro, Brasil.

Abstract: The urban expansion has been creating disorderly population agglomerations, which causes problems for the municipal administration. In order to reduce this type of problem, one of the ways to reorganize the territory is polycentrism, a concept that has been applied in a large part of the urban area of several countries such as the United States, China, and countries in Europe. Polycentrism can be understood as an urban area with a plurality of urban centers. There are two approaches to identify possible centralities: the morphological and the functional. In addition, no results were found from scientific studies that have used the variable slope of relief in the analysis of identification of urban centralities. Thus, the slope variable can be an impacting factor in determining a centrality or urban nucleus for Brazilian locations and which has similar characteristics of the study area. The aim of this work proposes a study for the identification of centralities or the possibility of identifying new urban centers, through the evaluation of the morphology of the land in the formation of sub-centers in the municipality of Barra do Piraí in the State of Rio de Janeiro, Brazil. Vector files were acquired from the IBGE 2018 cartographic base, which were later treated and analyzed.

Resumen

Målet med detta projekt har varit att utveckla en monteringsvänlig och kostnadseffektiv ljuddiffuser, en komponent som inte ska påverka ljudnivån och luftflödet för mycket, tillskillnad från den befintliga lösning som idag används i 3nine AB:s oljedimavskiljare. Examensarbetet följer den produktutvecklingsprocess som redogörs i boken Produktutveckling – Konstruktion och design av Karl T. Ulrich och Steven D. Eppinger. Där arbetet har anpassats för tidsramen på 10 veckor och delats upp i fyra faser. Fas1 – Förstudie, Fas 2 – faktainsamling, Fas 3 – Genomförande och Fas 4 – Rapportering. Den lösning som används idag består av fem vikta bitar sträckmetall som har sytts ihop med ståltråd, ljuddiffusern tar lång tid att montera ihop och att montera ned i maskinen. De fem vikta bitarna sträckmetall har vassa kanter efter klippning som försvårar monteringen ytterligare. En ljuddiffuser har en kostnad på 100 kr/st att framställa. För denna lösning togs mätvärden i 3nine AB:s verkstad fram som agerar som referensmätvärden, monteringstid – 333 [s], ljudnivå – 68 [dB], luftflöde – 319 [m ³/h] och DFA – index (mätvärde för monteringsvänlighet) – 5,4 %. Där 100 % ses som optimal monteringsvänlighet och högre DFA-index leder till reducerade kostnader. Då luft strömmar genom maskinen så påverkar detta mätvärdena och möjlig design av ny prototyper, men strömningslära är kunskaper som vi saknar och detta analyser med avseende på detta avgränsades bort. Genom Idéutvecklingsprocesser som Brainstorming, 6-3-5 Brainwritning, Morfologiskmatris, Pughmatris, konceptskisser, Virtuella koncept (3D-CAD) och friformsframställning (3D-utskrivning av prototyp) så togs fem prototyper fram som sedan testades för monteringstid, ljudnivå, luftflöde och DFA-index. Dessa tester resulterade i att det var en prototyp som utmärkte sig med förbättrade resultat jämfört med referensmätvärdena av befintliga ljuddiffusern. Mätvärden för prototypen ”45° väggen”, monteringstid – 16 [s], ljudnivå – 65 [dB], luftflöde – 342 [m ³/h] och DFA – index (mätvärde för monteringsvänlighet) – 93 %. Risk – och FEM-analys genomfördes på prototypen för att identifiera svagheter i konstruktionen, lösningar på dessa rekommenderas i form av små förändringar som t.ex. rundningar vid hörn. Dessa mätvärden redogör att den framtagna lösningen är bättre än dagens lösning och rekommenderas att implementeras och vidareutvecklas av företaget
The aim of this project has been to improve the existing noise diffuser used currently today in the oil-separatingmachines developed by 3nine AB. By reducing noise levels, increasing the air flow, increasing the “ease of assembly” and making it more cost effective. The thesis follows the product development process described in the book “Product Development - Construction and Design” by Karl T. Ulrich and Steven D. Eppinger. The work was adapted for a 10-week timeframe and divided into four phases. Phase 1 - Pre-Study, Phase 2 – Information gathering, Phase 3 - Implementation and Phase 4 - Reporting. The solution used today consists of five folded pieces of stretch metal that have been sewn together with steel wire, the noise diffuser takes a long time to assemble and to fit into the machine. The five folded pieces of stretch metal have sharp edges after cutting, which further complicates the assembly. The production cost for each diffuser is 100 kronor. For the present solution, the measurement values taken at 3nine AB's workshop were set as reference values, assembly time - 333 [s], noise level - 68 [dB], airflow - 319 [m³ / h] and DFA-index (measurement value for ease of assembly) - 5.4%. DFA-index when 100% is seen as the optimal ease of assembly and a higher DFA-index leads to reduced costs. As air flows through the machine, this affects the measured values and possible design of new prototypes, but fluid mechanics is one knowledge we lacked and therefor analysis of this was not possible and delimited. Through Idea Development Processes such as Brainstorming, 6-3-5 Brainwriting, Morphological Matrix, Pugh matrix, Concept Sketches, Virtual Concepts (3D-CAD) and Rapid prototyping (3D-prototype printing), five prototypes were produced, then tested for assembly time, noise level, airflow and DFA -index. These tests resulted in a prototype that featured improved results compared to the reference values of the existing noise diffuser. Measurement values for prototype "45° wall" where assembly time - 16 [s], noise level - 65 [dB], airflow - 342 [m³ / h] and DFA index - 93%. Risk-analysis and FEA was carried out on the same prototype to identify weaknesses in the design. The solutions to these weaknesses are recommended in the form of small design changes such as rounded sharp corners. These measured values state that the solution developed is better than today's solution and is recommended to be implemented and further developed by the company.

Resumen

The thesis focuses on the characterization of the alteration of the mineral and organic phases, investigated with different approaches, of human bone tissue from different burial contexts, with ages spanning from the Late Roman period to our time. This topic is very important in paleontological, archaeo-anthropological and forensic contexts in order to understand the taphonomic agents and then to provide biological data as possibly to discern human behavior in ancient funerary as well as in recent forensic contexts. It is well-known that peri and post mortem events may leave marks that have to be interpreted in the light of the state of the conservation or degradation of the skeletal remains. In fact, physical anthropologists are frequently required to date human bone remains, in order to recognize if osteological samples have an archaeological, historic or forensic interest. The determination of post mortem interval (PMI), the time elapsed between the death and the discovery of the corpse or skeletal remains, is extremely difficult to evaluate in absence of direct chronometric dating (e.g. C14), since bones might undergo several alterations, both structural and chemical, depending on the environment in which they deposited in. Because of bone tissue is an intimate association of mineral (carbonate-hydroxyapatite) and organic components (collagen) arranged in an ordinary structure, different levels of degradation are possible. Over time post mortem degradation is dominated by loss of structural collagen by collagenolytic enzymes, which caused a rapid swelling and hydrolysis of the protein fibers. Collagen dissolution is generally accompanied by the alteration of mineral crystals, which are vulnerable to diagenetic changes due to their small size. During diagenesis, the protein can be totally or partially removed and can replaced by inorganic precipitates, the most common beign hydroxyapatite, which in the process is subjected to recrystallization, ion exchange and substitution. As consequence, when depositional conditions are favorable for bone preservation, the mineral crystallinity increase, the porosity and chemical composition change. The quality and the assessement of organic and inorganic phase, can act positively or negatively both on bone mechanical properties in live, both on decomposition process after death, reducing or accelerating it. Several studies were performed to better understand the taphonomy of bone material during burial time. It appears that bone degradation depends on a wide range of environmental interactions, including biological, chemical and physical factors. These include: average temperature and humidity, microbilological composition and activity, soil chemistry (mineralogy and pH) and permeability, mechanical pressure and other numerous factors. Different type of bone degradation are observable at different scale of observation; particularly, in this study, bone preservation was investigated at macroscopic, biomolecular, microscopic, ultramicroscopic and chemical scale. The aim of this research is thus to further describe the impact of environmental conditions on bone preservation, and the effect of time, by applying and comparing the results from different analitical techniques. For this study 40 human skeletons of adult individuals from four different dated burial location in the Milan area were analyzed. The first one is a necropolis dated to the Late Roman age (3th-4th century AD), the second one is a 17th century AD mass grave, the third one is an ossuary contanining bones dated between 15th and 18th century AD, and the last one is a modern cemetery. The macroscopic analysis evaluated the general appearance of the remains and their state of preservation, through the observation of specific macroscopic parameters and morphological characteristics. The Luminol test, a fast and inexpensive method developed to detect blood traces, was performed to investigate the presence of haemoglobin preserved in bone. The histological analysis, conducted on calcified thin sections, considered the presence or absence of tunneling and bioerosion, in accordance to the Oxford Histological Index (OHI). Also, to evaluate the state of preservation of the organic component, primarily collagen, the samples were decalcified and stained with Hematoxylin and Eosin. Because of the lack of literature in this field, we created a new Decalcified Histological Index (DHI). Both calcified and decalcified bone thin sections were observed in transmitted and polarized light microscopy, in order to test the optical properties of structural components. Scanning electron microscope coupled with energy-dispersive X-ray spectroscopy (SEM-EDS) was used to evaluate exogenous chemical elements and minerals, adsorbed from burial environment, and histological changes, as well as recrystallization, tunnelling and fractures, due to fungal or bacteria action. X-ray micro-computed tomography of bone sections was performed at the SYRMEP beamline of the third-generation Synchrotron Light Laboratory (ELETTRA) located in Trieste (Italy), with the purpose to evaluate and quantify the preservation of bone structure, such as canals and lacunae, and the porosity changes due to diagenetic process. Fourier transform infrared spectrometry (FT-IR) and micro-spectrometry (mFTIR) were performed at Simon Fraser University (Burnaby) in Canada to investigate the preservation of both mineral and organic phases. Finally, 23 skeletons from the archaeological site of Travo (PC), dating from 7th-8th century AD, and their burial ground sediments were sampled and analyzed. Macroscopic, microscopic and chemical analyses were performed on bones to evaluate the tissue preservation state at different scales; the soil samples collected from the graves were characterized for color, particle size distribution, pH, organic carbon and calcium carbonate concentration. This study shows that macroscopic, biomolecular, microscopic, ultramicroscopic and chemical alterations follow independent paths that affect the bone preservation at different scales of observation. Therefore, the estimation of the diagenetic process cannot be limited to the macroscopic aspect of the bone tissue but must take into account biomolecular, microscopic and chemical alterations, since these may have affected the bone tissue differently at different scale. Bone degradation can be employed to estimate the post mortem interval, or to reconstruct the burial environment of human remains. As long as the evaluation of taphonomic alterations is performed at different scales with different ad hoc methodologies. In fact, age and environment can play an equal role on the degradation of organic and mineral phases, producing different effects on bone conservation at different levels.

Resumen

Indiana University-Purdue University Indianapolis (IUPUI)
Floods are one of the worst disasters in the United States. Each year, the government allocates a tremendous amount of manpower and money on flood prevention initiatives. As the first defense line, levees provide protection from temporary flooding (Makhdoom, 2013). These embankments are broadly classified according to the areas they protect, which could either be urban or agricultural levees within floodplains. In the U.S., most of the levees are handled by government agencies such as the U.S. Army Corps of Engineers and the Federal Emergency Management Services. On the other hand, non-levee embankments created by individual farmers (Olson & Morton, 2013) or naturally formed levee-like structures may not be in the government database. The initial purpose of this research was to assist Polis center on the “Mapping of Non-Levee Embankments in the Indiana” project. The non-levee embankments are not certified or engineered levee-like structures. They, therefore, impose lateral constraints on flood flows, reducing the floodplain storage capacity and increasing the flood velocity. These non-levee embankments can cause stream erosion and downstream flooding. Therefore, it is important to know the locations of these features. The first part of the proposed method adapted the Empirical Bayesian theorem and the low pass filter techniques to extract elevated linear features from LiDAR elevation data – Digital Elevation Model (DEM). The second part of the proposed methods combined the Minimum Bounding Circle (MBC) method and the Youden Index to locate the optimal threshold value that can be used to determine whether the extracted features are levee-like structures. The focus of this study is not only limited to artificial levee-like structures, but also takes the natural levees, or any potential levee-like structures into account because this study assumes all embankments play important roles during flood events.

Resumen

This item is only available electronically.
The ability to identify forest architecture in the geologic past has implications for our understanding of palaeoecological processes. The degree of canopy closure (or density of foliage) effects atmospheric circulation and hydrologic cycling, which in turn, can influence terrestrial temperature and rainfall patterns. Closed canopy forests are characterised by strong gradients in light intensity, which influence the chemistry and morphology of leaves. This study has used isotopic and morphological leaf traits from the modern closed canopy Daintree Rainforest in Queensland, which can also be measured from fossil leaves, to calibrate a multiproxy tool that characterises the spatial distribution of light intensity. Leaf area index (LAI) was used to quantify forest canopy closure. Changes in carbon isotope ratios (δ13C), leaf mass per area (LMA), undulation index (UI) and cell area (CA) all had linear correlations with increasing LAI from the canopy to the understory. Therefore, these traits can be used as a proxy for reconstructions. However, the magnitude of responses varies between species. A portion of species were unresponsive in UI. Therefore, this proxy may not be suitable for all species. Traits from leaves from beneath a gap in canopy closure and those from a drought experiment, did not deviate from the general gradient seen with LAI. The model used to predict LMA (petiole width2/leaf area) did not correspond with measured LMA and did not characterise the light gradient found within the Daintree rainforest. However, they did predict the average LMA of the rainforest. Investigations into inter-trait variations demonstrate that δ13C, CA and UI correlate with LMA, and CA correlates with UI. Results show several new leaf traits that can be used to identify the degree of shading in closed canopy forests in the fossil record and demonstrate how light gradients drive variation within a forest.

Resumen

A comprehensive worldwide review and revision of the genus Sternaspis (Polychaeta: Sternaspidae) is presented based on type material, or material collected from type localities. The phylogeny was reconstructed using morphological characters and PAUP* with maximum parsimony set as the criterion. The more important characters were: the form of pharyngeal spines or their apposition to each other within a row; the form or distribution of cuticular papillae; number of chaetal fascicles associated with the margins of the ventral shield; and the presence or position of the peg chaetae. Sternaspis scutata (Ranzani. 1817) is synonymised with three other species; S. costata Marenzeller, 1979 is synonymised with one other species. S. affinis Stimpson, 1864 and S. spinosa Sluiter, 1882 are emended. S. fossor var. africana Augener, 1918 is raised to species status as S. africana. Two new species, S. andamana and S. gudmundi are also described. Comments on all valid species are provided.

Resumen

Abstract The Indian initiative for creating mutant resources in rice has generated 87,000 mutants in the background of a popular drought- and heat-tolerant upland cultivar, Nagina 22 (N22), through EMS mutagenesis. So far, 541 macro-mutants from this resource have been identified, maintained in the mutant garden and characterized in detail based on 44 descriptors pertaining to distinctness, uniformity and stability (DUS) of rice and other agronomic parameters. The similarity index of the mutants was more than 0.6 for nearly 90% of the mutants with respect to DUS descriptors, further establishing the validity of the mutants. The available high-quality sequence resource of N22 has been improved by reducing the gaps by 0.02% in the coding sequence (CDS) region. This was made possible using the newly synthesized whole-genome data of N22 which helped to remove 9006 'Ns' and replace 12,746 existing nucleotides with the accurate ones. These sequence and morphological details have been updated in the mutant database 'EMSgardeN22'. Further, 1058 mutants have been identified for low-P tolerance, tolerance to sheath blight, blast, drought, heat, higher photosynthetic efficiency and agronomic and root traits from this resource. A novel herbicide-tolerant (imazethapyr) mutant earlier identified and characterized from this resource is now being used in introgressing the herbicide-tolerant trait in eight major rice varieties in India. Further, robust and simpler screening systems have been tested for studying low-P tolerance of the mutants. A grain-size mutant, heat-tolerant mutant, drought-tolerant mutant, stay-green mutant and low-P tolerant and water-use efficient high-root-volume mutants have been characterized at morphological and molecular levels. A brief account of all these mutants, the entire mutant resource and the elaborate trait-based screenings is presented in this chapter.

Resumen

Endplates play a major role in intervertebral disc (IVD) health, but the opposite could also be true with changes in IVD affecting the morphological features of endplates. We here hypothesize that changes in biomechanical environment due to disc herniation will change the thickness and apparent density of the endplates at the index level.

Laser diagnostics and radiative heat transfer investigations on flame soot particulates appears to be seriously influenced by the a priori uncertainties connected to the lack of knowledge about the physical and chemical properties of the media under test. Both the uncertainty about soot refractive index [1] and [2],[3] morphology are demonstrated to substantially influence the effectiveness of optical in-situ scattering / absorption measurements.

Resumen

The paper presents work on two databases of vernacular Old East Slavic writing, viz. the databases of birchbark letters and epigraphy. The task is to link the information of archaeological/historical and linguistic character, namely, the possibility of simultaneous expansion and updating of the database and of a linguistic corpus that enables grammatical and lexical search. The online database Old East Slavic birch bark letters and the section of the historical subcorpus of the Russian National corpus containing birch bark letters call for an integration. This includes, in particular, creating an online workstation for the morphological markup of texts linked to the database entries, the possibility of exporting XML-databases with morphological markup to include them in the RNC, the possibility of automatic generation of forward and backward word indices to the database on the basis of the marked corpus, mutual verification of previously compiled manually indices to the book by A. A. Zalizniak The Old Novgorod Dialect (a new updated edition of this book is being prepared) and markup of the corpus. Creation of a new database on the Old East Slavic epigraphy is designed to overcome the fragmented state of the publications and research in the field, combining the material accumulated by the scholars into a single electronic resource. From the point of view of programming, the architecture of the epigraphy database is analogous to the one of the birch bark database, which makes it possible to create an annotated corpus of the Old East Slavic epigraphy.
