Abstract:

Severe drought conditions contributed to three mass fish mortality events in the Darling River near Menindee, part of the Murray–Darling Basin, Australia, during the summer of 2018–19. An independent assessment recommended the need for improved modelling approaches to identify when sections of rivers may be more susceptible to fish kill events. We present a geographic information system (GIS)-based tool that combines meteorological forecasts with river flow and algal biomass datasets to identify river reaches where additional stresses on fish health may produce an increased risk of mass fish deaths. At present the tool is still in development and will require the addition of extra datasets and testing using historical datasets to further validate its accuracy. Despite the tool being in its development stage, the decision support tool has been widely accepted and provides natural resource managers with a rapid way to understand and communicate risks to fish health, supporting improved water management options across the Murray–Darling Basin that may ultimately help reduce the frequency and severity of large-scale fish mortality events.

Abstract:

The application of river-system models to inform water-resource planning and management is a growing global phenomenon. This requires models to be applied so that they are useful to water decision makers charged with setting targets that provide adequate water flows to sustain landholders and communities. This article examines why and how the innovative application of river-system models can facilitate interactions between water science and water management in Australia’s Murray–Darling Basin (the Basin). A trajectory river-modelling method was applied to run multiple short historical climate sequences through a river-system model to provide historical probabilities. These can allow better assessment of the risks and impacts associated with stream flow and water availability. This method allows known historical variability to be presented, and produces relevant results for a 10–15-year water-sharing plan lifetime. The benefits were demonstrated in the Basin’s Lachlan Catchment where modelled river-flow results demonstrated the increased variability between shorter 15-year sequences than for a single 114-year run. This approach highlighted the benefits of expressing modelling results as historical probabilities to inform short-term and strategic water-planning efforts.

Abstract:

Stock enhancement is a management tool used for fishery recovery worldwide, yet the success of many stocking programs remains unquantified. Murray cod (Maccullochella peelii) and golden perch (Macquaria ambigua) are important Australian recreational target species that have experienced widespread decline. Stocking of these species has been undertaken for decades, with limited assessment of effectiveness. A batch marking and recapture approach was applied to assess stocked Murray cod and golden perch survival, contributions to wild fisheries, and condition in rivers and impoundments. Stocked fish were marked with calcein. Marked fish were detected during surveys undertaken 3 years and 10 months from initial marking, and it is probable that marks will persist beyond this time. The proportion of calcein marked fish in the population sub-sample whose age was equal to, or less than, the number of years since release, varied by 7–94% for Murray cod, and 9–98% for golden perch. Higher proportions of marked fish were found in impoundments than rivers. Marked Murray cod had significantly steeper length–weight relationships (i.e. higher weight at a given length) to unmarked fish. Our results show that application of methods for discriminating stocked and wild fish provides critical information for the development of adaptive, location-specific stocking strategies.

Abstract:

Over the past decade, there intense consideration of managing flows in the River Murray to provide environmental benefits. In 1990 the Murray-Darling Basin Ministerial Council adopted a water quality policy: To maintain and, where necessary, improve existing water quality in the rivers of the Murray-Darling Basin for all beneficial uses - agricultural, environmental, urban, industrial and recreational, and in 1994 a flow policy: To maintain and where necessary improve existing flow regimes in the waterways of the Murray-Darling Basin to protect and enhance the riverine environment. The Audit of Water Use followed in 1995, culminating in the decision of the Ministerial Council to implement an interim cap on new diversions for consumptive use (the “Cap”) in a bid to halt declining river health. In March 1999 the Environmental Flows and Water Quality Objectives for the River Murray Project (the Project) was set up, primarily to establish water quality and environmental flow objectives for the River Murray system. A Flow Management Plan will be developed that aims to achieve a sustainable river environment and water quality, in accordance with community needs, and including an adaptive approach to management and operation of the River. It will lead to objectives for water quality and environmental flows that are feasible, appropriate, have the support of the scientific, management and stakeholder communities, and carry acceptable levels of risk. This paper describes four key aspects of the process being undertaken to determine the objectives, and design the flow options that will meet those objectives: establishment of an appropriate technical, advisory and administrative framework; establishing clear evidence for regulation impacts; undergoing assessment of environmental flow needs; and filling knowledge gaps. A review of the impacts of flow regulation on the health of the River Murray revealed evidence for decline, but the case for flow regulation as the main cause is circumstantial or uncertain. This is to be expected, because the decline of the River Murray results from many factors acting over a long period. Also, the health of the river varies along its length, from highly degraded to reasonably healthy, so it is clear that different approaches will be needed in the various river zones, with some problems requiring reach or even point scale solutions. Environmental flow needs have been determined through two major Expert Panel reports that identified the ecological priorities for the river. The next step is to translate these needs into feasible flow management actions that will provide the necessary hydrological conditions. Several investigations are underway to recommend options for flow management. Two important investigations are described in this paper: how to enhance flows to wetlands of national and international significance, and how to physically alter or change the operation of structures (including a dam, weir, lock, regulator, barrage or causeway), to provide significant environmental benefits. Early modelling suggests that the only option which has a positive environmental effect in all zones of the River is a reduction in overall water consumption.

Abstract:

This study was designed to examine any links between the concept of flow or optimal experience and the creative output of student compositions. The creative products of group compositions by university students (n=45) were rated for creativity and on a number of standard criteria and compared with scores obtained from Experience Sampling Forms (Csikszentmihalyi & Csikszentmihalyi, 1988) completed by each participant. A significant correlation was found between optimal experience or flow levels of students and the quality of their group compositions as measured by creativity ratings. Some implications for educators and learners in the music classroom are explored and a proposed self-directed learning tool is discussed. Some of the issues on the assessment of creativity in music raised by Sheridan & Byrne (2002) are also discussed. This paper highlights the subjective nature of existing assessment procedures, considering whether examiners need extended criteria as opposed to a single dimension of creativity. The formative assessment nature of the flow paradigm is also explored.

Abstract:

Introduction and purpose. Ocular blood flow (OBF) impairment is observed in more than 50 % of all ocular disorders. There is often an association with systemic hemodynamics. To evaluate ophthalmoplethysmographic parameters in normal subjects taking into account individual frequency-response OBF characteristics. Methods. 251 subjects without ophthalmic pathological findings (except incipient cataract in elderly) were examined using ophtalmoplethysmograph OP-A (SKTB Optimed, Moscow, Russia, calibrated by optimized method). Ocular biometry, intraocular pressure, blood pressure (BP), heart rate (HR) were also evaluated. Probands were divided into subgroups by gender and age. Results. The duration of the anacrotic part of the pulse curve ranged between 0.23±0.04 sec and 0.32±0.06 sec; the duration of the catacrotic part of the pulse curve was between 0.58±0.09 sec and 0.75±0.11 sec; the anacrotic/catacrotic ratio ranged between 0.34±0.07 and 0.55±0.1; the systolic increase of ocular anterior segment volume (SIOASV) ranged between 7.35±3.21 μl and 11.15±4.42 μl; SlOASV per minute was between 464.1±153.6 μl and 578.1±175.7 μl. Time characteristics of the plethysmographic curve highly correlate with HR. Conclusions. Ophtalmoplethysmography is a valuable tool for OBF evaluation. Normal OBF ophthalmoplethysmographic parameters vary significantly (ranging between 165.6 and 1388.4 μl/min). OBF evaluation should not be performed without systemic BP and HR examination.

Abstract:

The assessment of systemic blood flow is a complex and comprehensive process with clinical, laboratory, and technological components. Despite recent advancements in technology, there is no perfect bedside tool to quantify systemic blood flow in infants that can be used for clinical decision making. Each option has its own merits and limitations, and evidence on the reliability of these physiology-based assessment processes is evolving. This article provides an extensive review of the interpretation and limitations of methods to assess systemic blood flow in infants, highlighting the importance of a comprehensive and multimodal approach in this population.

Abstract:

Many of the world’s rivers have been found to be sources of CO2 to the atmosphere, however, there has been limited assessment in arid regions. This analysis of a long-term (1979–2013) dataset (n = 3496) along Australia’s largest river system (River Murray) showed that there were sustained high pCO2 (carbon dioxide partial pressure) levels, ranging from 1210 ± 107 to 3066 ± 579 µatm along the main river channel, and 5114 ± 1221 µatm on the major tributaries. As a consequence, the River Murray is a significant source of CO2 to the atmosphere, with an estimated average annual (±s.d.) flux of 218 ± 98 g C m−2 year−1 and total emissions of 355 000 ± 29 000 t CO2 year−1 over a total river area of 386 km2 from below Lake Hume to Tailem Bend, although there is some uncertainty with gas transfer coefficients. Supersaturation with CO2 relative to the atmosphere was maintained even under drought conditions with minimal external carbon inputs, suggesting internal carbon cycling and respiration is important in driving net CO2 production. Supersaturation of the river water relative to calcium carbonate minerals was also observed under low flow conditions. Hydro-climatic changes could be having significant impacts on the CO2 system in the River Murray and other arid river systems.

Abstract:

Abstract Objective: The objective of this study was to investigate the clinical applicability of navigated blood flow imaging (BFI) in neurovascular applications. BFI is a new 2-dimensional ultrasound modality that offers angle-independent visualization of flow. When integrated with 3-dimensional (3D) navigation technology, BFI can be considered as a first step toward the ideal tool for surgical needs: a real-time, high-resolution, 3D visualization that properly portrays both vessel geometry and flow direction. Methods: A 3D model of the vascular tree was extracted from preoperative magnetic resonance angiographic data and used as a reference for intraoperative any-plane guided ultrasound acquisitions. A high-end ultrasound scanner was interconnected, and synchronized recordings of BFI and 3D navigation scenes were acquired. The potential of BFI as an intraoperative tool for flow visualization was evaluated in 3 cerebral aneurysms and 3 arteriovenous malformations. Results: The neurovascular flow direction was properly visualized in all cases using BFI. Navigation technology allowed for identification of the vessels of interest, despite the presence of brain shift. The surgeon found BFI to be very intuitive compared with conventional color Doppler methods. BFI allowed for quality control of sufficient flow in all distal arteries during aneurysm surgery and made it easier to discern between feeding arteries and draining veins during surgery for arteriovenous malformations. Conclusion: BFI seems to be a promising modality for neurovascular flow visualization that may provide the neurosurgeon with a valuable tool for safer surgical interventions. However, further work is needed to establish the clinical usefulness of the proposed imaging setup.

Abstract. The necessity for developing Hydropower plants a renewable energy source has emerged due to increase in energy demand and environmental concern, as non-renewable sources produce greenhouse gasses. Location analysis methodology for hydropower development has formerly depended upon onsite surveys and manual work which are tedious, time consuming and costly as compared to the work done on GIS environment. In current study an attempt has been made to construct a tool that integrate and automate the various hydrology tools available in QGIS for finding hydro potential site. Each tool perform different function and are linked according to the workflow as majority of these tools uses the output of the previous tool and thus are interdependent. Geoprocessing analysis is performed on DEM to generate fill sink, flow direction, flow accumulation, identification of stream network, head (falling height). Hydrological data (runoff) and Pour point location is taken as input to generate discharge value and watershed contributing to that point location respectively. Finally hydro potential is calculated by the tool and sites having high potential are identified. The model is tested on Hasdo bango hydro power plant site located in Korba district of Chhattisgarh. The hydro potential of the site evaluated from the model is 112MW which is close to the total installed capacity of the existing hydro power plant of 120MW.

Abstract:

Coronary flow velocity reserve (CFVR) reflects global coronary atherosclerotic burden, endothelial function and state of the microvasculature. It could be measured using transthoracic Doppler echocardiography in a non-invasive, feasible, reliable and reproducible fashion, following a standardised protocol with different vasodilatory stimuli. CFVR measurement is a recommended complement to vasodilator stress echocardiography. It could serve as a diagnostic tool for coronary microvascular dysfunction and in the setting of epicardial coronary artery stenoses could help in identification and assessment of functional significance of coronary lesions and follow-up of patients after coronary interventions. CFVR has also a prognostic significance in different clinical situations.

Abstract:

This investigation focuses on the application of the computational fluid dynamics tool FLUENT to the study of flows over the NACA 63–415 airfoil at various angles of attack. With the aim of selecting the most suitable turbulence model to simulate flow around ice-accreted airfoils, this work concentrates on assessing the prediction capabilities of various turbulence models on clean airfoils at the large angles of attack that cause highly separated flows to occur. The study was undertaken by conducting simulations with the one-equation Spalart-Allmaras (SA) model, the two-equation RNGk-ϵand SSTk-ωmodels, and the Reynolds stress model (RSM). Domain discretization was carried out using general quadrilateral grids generated with GAMBIT, the FLUENT preprocessing tool. Comparisons were made with available experimental data.

Abstract:

Flow cytometry is the gold-standard laser-based technique to measure and analyze fluorescence levels of immunostaining and DNA content in individual cells. It provides a valuable tool to assess cells in the G0/G1, S, and G2/M phases, and those with polyploidy, which holds prognostic significance. Frozen section analysis is the standard intraoperative assessment for tumor margin evaluation and tumor resection. Here, we present flow cytometry as a promising technique for intraoperative tumor analysis in different pathologies, including brain tumors, leptomeningeal dissemination, breast cancer, head and neck cancer, pancreatic tumor, and hepatic cancer. Flow cytometry is a valuable tool that can provide substantial information on tumor analysis and, consequently, maximize cancer treatment and expedite patients’ survival.

Abstract:

Functional tests used in the catheterization laboratory have emerged as a very important adjunctive tool to coronary angiography that can identify patients with myocardial blood flow impairment. Fractional Flow Reserve (FFR) measurement is highly recommended for detection of ischemia-related coronary lesion(s) when objective evidence of vessel-related ischemia is not available. Recently, the much simpler instantaneous wave free ratio (iFR) was proposed as an alternative to FFR without the requirement for administration of vasodilators. More user-friendly techniques like iFR might further contribute to value-based care in coronary interventions.

Abstract:

Information on the magnitude and variability of flow regimes at the river reach scale is a central component of most aspects of water resource and water quality management. However, many decisions are made within catchments for which there are no measured flow data. To meet this challenge, a suite of modelling techniques to assist in the estimation of natural and artificially influenced river-flows at ungauged sites has been developed. This paper summarises these models and how they are incorporated within the GIS framework of the Low Flows 2000 software package. The paper will also describe the implementation of Low Flows 2000 within England and Wales by the Environment Agency, and the use of the system in supporting the implementation of the Environment Agency’s Catchment Abstraction Management Strategy. This strategy is focused on the delivery of sustainable abstraction licensing and will contribute to the implementation of the Water Framework Directive within England and Wales.

Abstract:

Planning theories suggest a stepwise structure for organizing programs; evaluate current status with a needs assessment, identify strengths, weaknesses or gaps, use tools such as a logic model to plan, then implement and evaluate programming (Kettner et al., 2017). The National Agriculture in the Classroom organization and its state affiliates have the responsibility of providing agricultural education content to school-aged children and teachers to increase agricultural literacy (NAITC, n.d.). The Longhurst Murray Agricultural Literacy Instrument (LMALI) is a modern, valid tool to assess proficiency level of students participating in such programming (Longhurst, et al., 2020). Tri-Center Elementary in Iowa administered the LMALI to kindergarten through fifth grade students in March 2021. The findings from this case study suggest recommendations to state and national program planners to improve effectiveness of agricultural literacy outreach programs.

Flow cytometry is one of the principal technologies employed for MRD monitoring due its rapid turnaround time, similarity to diagnostic immunophenotyping, and widespread availability of instrumentation in clinical laboratories. The immunophenotypic identification of neoplastic cells relies on the altered expression of proteins or antigens by neoplastic cells in comparison to their normal counterparts of similar lineage and maturational stage, and represents an integration of alterations in the underlying genetic program that are responsible for neoplasia. However, important technical and interpretative differences exist between diagnostic immunophenotyping and MRD monitoring that require special attention to ensure consistent quality, not the least of which is appropriate assay validation. In addition, there is also significant variability in the methods of sample preparation, reagent panels used, and data analysis strategies employed in clinical flow cytometry laboratories and this variability extends to MRD testing. The consequence is variability in quality between laboratories for MRD testing, even laboratories considered knowledgeable or experienced. This lack of standardization represents a major challenge to widespread implementation of MRD monitoring by flow cytometry. Consequently, on-going efforts by the Childrens Oncology Group and Foundation of the National Institute of Health are focused on improving standardization of B lymphoblastic leukemia MRD testing for clinical trials and ultimately all patients. Nevertheless, in experienced laboratories using a standardized protocol, MRD monitoring by flow cytometry in B lymphoblastic leukemia has been shown to be capable of producing reproducible results at both the technical level and relative to patient outcomes on clinical trials, emphasizing that the technology itself allows for reproducible testing and that the current variability is largely due to implementation details and interpretive skills. Whether this degree of comparability can be achieved for T lymphoblastic leukemia or acute myeloid leukemia remains to be demonstrated. A related issue is the level of sensitivity that is both achievable and desirable for MRD monitoring at particular time points after therapy. Current flow cytometric assays have a routine limit of detection at early time points after therapy of roughly 0.01% of nucleated cells for acute lymphoblastic leukemia and 0.1% for acute myeloid leukemia with a higher sensitivity possible for subsets of patients having either more frankly aberrant immunophenotypes or reduced background populations of similar immunophenotype. Interestingly, our recent comparison of flow cytometry with high throughput sequencing in B lymphoblastic leukemia suggests that increased assay sensitivity does not necessarily improve risk stratification at early time points and that the moderate sensitivity of current flow cytometric assays is adequate for this purpose. However, higher sensitivity assays will likely be more important at later time points further from therapy. Multiple studies have now demonstrated the prognostic significance of MRD detection in acute leukemia after therapy or prior to bone marrow transplantation using flow cytometry. This raises the possibility as to whether the assessment of MRD after therapy can be used not only to assess response to therapy, but as a surrogate biomarker for outcome to expedite the new drug approval process.

Abstract:

The aim of this article is to thoroughly analyse the influence of condensation models on the modelling of condensation phenomena in transonic flow of moist air. The reason for the study was the fact that different condensation models are used by researchers to obtain satisfactory results of numerical modelling. The condensation models tested herein differ in the nucleation rate formula and the droplets growth equation. Four most often used condensation models were selected for detailed investigations. The results obtained from each model were compared with experiments for the nozzle flow. The main focus was on the location of the onset of the nucleation process. Moreover, the droplets growth intensity was compared and discussed. The nozzle flow CFD calculations were performed using the ANSYS Fluent commercial tool. Finally, the condensation model which is the most suitable for the moist air transonic flow was recommended.

Abstract:

Flow sensors are very essential in many aspects of our daily lives. Many of the industrial processes need a very consistent flow sensor to monitor and check for irregularities in their system. Therefore, flow sensor is an important tool for advanced operation in industrial environment. In this paper, the design and development of a 3D fabricated flow sensor was carried out using SolidWork 3D CAD. SolidWork Flow Simulation was used to model the effect the turbine flow sensor would have on a constant flowing water while MATLAB Simulink flow graph was created to visualize the effect of turbine flow sensor response with voltage input. Afterwards, the design was 3D printed using UP Plus 2 3D printer. The experimentation involved selection of sensors, coding to control the turbine flow sensor and automatic data logging and storage. During the design phase, the sensors and actuators were assembled using locally sourced material. Subsequently, under controlled laboratory environment, the turbine flow sensor was tested using a DC motor which was programmed to control the revolution per minute(rpm) of the turbine flow sensor. The rpm and velocity of the turbine flow meter was measured and stored in a database via Microsoft Excel using Cool Term Software. A total number of 517 readings were analysed to evaluate the performance of the turbine flow sensor. The result shows that the turbine flow meter is responsive to the motor input voltage and yielded accurate measurement of rpm and velocity of turbine flow meter.

Abstract:

In order to assess the remaining life of gas turbine critical components, it is vital to accurately define the aerothermodynamic working environments and service histories. As a part of a major multidisciplinary collaboration program, a benchmark modeling on a practical gas turbine combustor is successfully carried out, and the two-phase, steady, turbulent, compressible, reacting flow fields at both cruise and takeoff are obtained. The results show the complicated flow features inside the combustor. The airflow over each flow element of the combustor can or liner is not evenly distributed, and considerable variations, ±25%, around the average values, are observed. It is more important to note that the temperatures at the combustor can and cooling wiggle strips vary significantly, which can significantly affect fatigue life of engine critical components. The present study suggests that to develop an adequate aerothermodynamics tool, it is necessary to carry out a further systematic study, including validation of numerical results, simulations at typical engine operating conditions, and development of simple correlations between engine operating conditions and component working environments. As an ultimate goal, the cost and time of gas turbine engine fleet management must be significantly reduced.

Abstract:

The advantages and disadvantages of existing tools for calculating passenger flow are shown using the example of the city of Moscow.The objective of the research was to assess possibilities of using Wi-Fi data as a tool for analysing passenger flow. The authors used two types of Wi-Fi scanners and a tool they developed to analyse the collected data. The primary results of the study demonstrate the possibility of practical application of Wi-Fi data to analyse passenger flow.The described empirical studies, particularly data received from the portable Wi-Fi scanner, have shown that more than 20% of mobile devices in urban public transport and metro are used with Wi-Fi enabled, which is clearly not enough to get results necessary for comprehensive and detailed analysis of passenger flows. Nevertheless, the accumulating data allow to get possibility to forecast general passenger flow.A portable Wi-Fi scanner does not provide an opportunity to extensively capture a large area of the surveyed territory in real time (stops of urban public transport, locations where passengers enter the metro, etc.). Stationary Wi-Fi scanners could increase the amount of data and, accordingly, significantly adjust the results obtained. This enhancement could also be achieved through expansion of adoption of the tool of studying passenger flow to urban railways, i.e., in case of Moscow, to Moscow Central Circle and Moscow Central Diameters, as those routes provide Wi-Fi access at stations and in coaches.Data collected from Wi-Fi scanners can be an additional tool to other data sources, such as validation, automatic systems of passenger flow monitoring, and data obtained from cellular operators. For this reason, the further research in the field of Wi-Fi analytics along with development of technology in the field of existing data sources of passenger flow monitoring may result in better calculation of passenger flow.

Abstract:

This study analyzes the differences between wet and dry swallows; a manofluorogram is used to determine forces that affect pharyngeal bolus flow. By defining bolus pressures, many of the limitations of pharyngeal manometry are surmounted. This makes manometry a more useful clinical tool. The study results indicate that only a small portion of pharyngeal-generated pressure is directly applied to the bolus. The manofluorogram demonstrates that bolus transit relies on the synergistic action of two pumps—the oropharyngeal propulsion pump and the hypopharyngeal suction pump. A technique is illustrated for quantifying the forces that affect bolus flow. Quantification of force can differentiate abnormal forces responsible for lingual, pharyngeal, and hypopharyngeal pathology in dysphagic patients. The degrees of impairment can be measured.

ABSTRACTObjectivesTo evaluate the psychometric properties of HEARTSMAP, an emergency psychosocial assessment and management tool, and its impact on patient care and flow measures.MethodsWe conducted the study in two phases: first validating the tool using extracted information from a retrospective cohort, then evaluating implementation on a prospective cohort of youth presenting with mental health complaints to a tertiary Pediatric Emergency Department (PED). In phase 1, six PED clinicians applied HEARTSMAP to extracted narratives and we calculated inter-rater agreement for referral recommendations using Cohen’s Kappa and the sensitivity and specificity for identifying youth requiring psychiatric consultation and hospitalization. In phase 2, PED clinicians prospectively used HEARTSMAP and we assessed the impact of the tool’s implementation on patient-related outcomes and Emergency department (ED) flow measures.ResultsWe found substantial agreement (κ=0.7) for cases requiring emergent psychiatric consultation and moderate agreement for cases requiring community urgent and non-urgent follow-up (κ=0.4 each). The sensitivity was 76% (95%CI: 63%, 90%) and specificity was 65% (95%CI: 55%, 71%) using retrospective cases. During pilot implementation, 62 patients received HEARTSMAP assessments: 46 (74%) of HEARTSMAP assessments triggered a recommendation for ED psychiatry assessment, 39 (63%) were evaluated by psychiatry and 13 (21%) were admitted. At follow-up, all patients with HEARTSMAP’s triggered recommendations had accessed community resources. For those hospitalized for further psychiatric care at their index or return visit within 30 days, 100% were initially identified by HEARTSMAP at the index visit as requiring ED psychiatric consultation.ConclusionsHEARTSMAP has strong reliability, and when applied prospectively is a safe and effective management tool.

Full text

Abstract:

A novel prediction tool is presented as a component of the Habitat Evaluation Model (HEM), which allows the assessment of the ecological status of impounded water bodies based on environmental factors that were shown in literature to correlate with the abundance of benthic macro-invertebrates. Main model parameters are the observed grain sizes and depth-averaged flow velocities obtained from a hydrodynamic simulation. The tool was tested in three Austrian river reaches. It was found that the river lengths predicted to be ecologically affected by the impoundments were substantially shorter for mean flow conditions than previously assessed when employing a physical mapping approach. The differences disappeared for low discharge conditions. The numerical prediction tool allows us to perform a status assessment for discharge conditions, which are potentially more representative of the annual discharge spectrum than those within the in-situ observable range. This property, thus, bears the potential to facilitate the recommendation of sediment management strategies in impounded river reaches in the future.

The paper describes the structural design, simulation and proper manufacture of a tool for manufacturing of test samples in spherical form. This shape is essential for an innovative assessment of solder wettability, since the small sphere by its ideal shape represents the total non-wettability of substrate surface. In order to verify the design of the shaping tool, a simulation software, type Deform was used, which allowed the FEM analysis of plastic flow in the tool cavity. Just after successful computer simulation, a shaping tool was designed and then manufactured in laboratory conditions, thus the fabrication of test samples in spherical form was successfully tested.

Abstract:

e14089 Background: Selecting the right clinical trials for patients remains a challenging job. The better the match between a clinical trial and the target patient population before conducting a study, the more likely the study will successfully reach the target goal of recruitment. We developed a feasibility assessment scoring system based on our vast clinical research experience, managing multiple sites across a large health system, applicable to oncology as well. Methods: Our feasibility team (FT) is responsible for identifying clinical trials and determining if they are an appropriate match for our institution and unique patient population. Once a potential trial is identified, FT performs a feasibility assessment of the research protocol to determine the resources required to conduct the trial. We developed a Clinical Trial Feasibility Assessment & Start-up Tool (CTFAST) to help sites streamline their feasibility assessments and track their trial through the start-up phase. With CTFAST a feasibility score is generated based on the cumulative value assigned to several items such as: sponsor, study type, pharmacokinetic studies, trial phase, etc. A feasibility scale is assigned as follows: > 25 – Accepted; 15-25 – On Hold; < 15- Rejected. Accepted studies are assigned a color coded priority track (fast, intermediate, routine), that allows team members to prioritize their studies accordingly. Once a study is accepted, the study is processed for enrollment. Results: CTFAST has increased productivity and clinical trial revenues by 40%. CTFAST allows for early identification of bottlenecks in workflow, thereby improving outcomes. By appropriately matching of clinical trials to our site, enrollments increased by 50% with an expanded clinical trial portfolio across 9 different departments. Study start-up times have been reduced to a minimum of 21 days and the use of time & effort has been optimized. Conclusions: CTFAST is replicable across all clinical trial sites and provides an expansive and critical feasibility analysis that is not attainable by traditional querying of investigators and questionnaires. It is an excellent work flow improvement tool as it critically analyzes all aspects of a study, prior to enrollment. When conducting an effective feasibility analysis the clinical trial site can optimize clinical trial outcomes.

Abstract:

The obligatory path towards a lean manufacturing organization requires assessment and monitoring. However, a lean assessment framework is not yet available for the engineer to order (ETO) scenario. This work explored ten lean ETO maturity principles—identified from the literature—that take insight from three formally defined sets (Toyota Way, lean construction, and lean product development principles). A practical assessment model was proposed based on the evaluation of ten lean ETO objective criteria (four with mathematical formulation) and was validated on a real industrial case. A problem-solving tool, including a new lean tool, called the Problem Focus Matrix (PFM), was also presented; this tool was aimed toward development of an integrated framework that would include the organization mission, management, and continuous improvement.

Food traceability is a support tool for preventing and improving food safety problems. The purpose of food traceability is to collect the flow and transformation information of food-related materials in the food chains. When faced with a food safety crisis, we can find the source of the problem and track the flow of products from the information, and effectively carry out food recalls. In this paper, the status of food traceability in China is deeply analyzed from the laws, regulations, standards, traceability techniques and systems construction, and validity of internal and external traceability in food chains is assessed retrospectively. Then some recommendations for the further development of China's food traceability are proposed.

Abstract:

ABSTRACTGenetic defects of the immune system are referred to as primary immunodeficiencies (PIDs). These immunodeficiencies are clinically and immunologically heterogeneous and, therefore, pose a challenge not only for the clinician but also for the diagnostic immunologist. There are several methodological tools available for evaluation and monitoring of patients with PIDs, and of these tools, flow cytometry has gained prominence, both for phenotyping and functional assays. Flow cytometry allows real-time analysis of cellular composition, cell signaling, and other relevant immunological pathways, providing an accessible tool for rapid diagnostic and prognostic assessment. This minireview provides an overview of the use of flow cytometry in disease-specific diagnosis of PIDs, in addition to other broader applications, which include immune phenotyping and cellular functional measurements.

Abstract:

In this article a procedure is introduced to improve transparency and reliability of results for the selection of material flow design alternatives including machine tools and other capital-intensive goods. In the design phase of material flow planning projects, key performance indicators (KPIs) for design alternatives including processing as well as intralogistics elements can be derived using simulation. Using the state of the art method in value stream design and simulation often volatile input data is taken into account only in the simulation itself, but not in the downstream comparison of alternative designs, which could lead to imprecise conclusions and therefore to wrong investment decisions. To overcome this issue and to consider variability in the whole simulation phase and a subsequent decision making process, a multi-criteria decision analysis (MCDA) with two fuzzy representations is proposed and discussed here with the aim of helping practitioners to get more competitive value streams. A further goal of the article is the comparison between both forms used for fuzzy representation. Using the design example of machine tool-intralogistics systems obtained results are discussed.

Abstract:

Magnetic resonance imaging (MRI) has become an important tool for the clinical evaluation of patients with cardiac and vascular diseases. Since its introduction in the late 1980s, quantitative flow imaging with MRI has become a routine part of standard-of-care cardiothoracic and vascular MRI for the assessment of pathological changes in blood flow in patients with cardiovascular disease. More recently, time-resolved flow imaging with velocity encoding along all three flow directions and three-dimensional (3D) anatomic coverage (4D flow MRI) has been developed and applied to enable comprehensive 3D visualization and quantification of hemodynamics throughout the human circulatory system. This article provides an overview of the use of 4D flow applications in different cardiac and vascular regions in the human circulatory system, with a focus on using 4D flow MRI in cardiothoracic and cerebrovascular diseases.

Flow cytometry has become the method of choice to measure the DNA content (genome size) in plants. Ease of sample preparation, fast acquisition, and accurate measurements have made the method popular in the domains of plant cell biology, systematics, evolution, genetics and biotechnology. Although the cell wall is a problem when isolating plant cells, cytometry remains a powerful tool in plant sciences. Based on our 30-years’ experience in this field, this review will focus at first on genome size measurement using simply isolated nuclei: the good practice for acquisition, nuclei isolation, appropriate buffers, kind of tissues to use. The second part will briefly review what kind of measurements it is possible to make in plant cytometry, and for what purpose: base composition, ploidy level, cell cycle, endoreplication, seed screening, and nuclei/chromosomes sorting. We will address troubleshooting. The commonly-used mathematic tools will be discussed.
