    This presentation outlined the implementation processes used by TransCanada for its wind power projects. Locations selected by TransCanada for its wind farms must have strong, consistent resources and also be located near transmission sites. While rules and regulations vary in different jurisdictions, all wind farm projects must be acceptable to local stakeholders and are required to undergo the environmental assessment (EA) process. The selected sites are also subjected to detailed constraints analyses to ensure minimal adverse environmental and social impacts. Constraints management is also used to control project costs. The Cartier Wind Energy Project was used in this presentation as a case study demonstrating TransCanada's selection process. Details were also provided for TransCanada's Baie-des-Sable wind project which is located on private agricultural land.

  8. Additive Manufacturing in Production: A Study Case Applying Technical Requirements

    Science.gov (United States)

    Ituarte, Iñigo Flores; Coatanea, Eric; Salmi, Mika; Tuomi, Jukka; Partanen, Jouni

    Additive manufacturing (AM) is expanding the manufacturing capabilities. However, quality of AM produced parts is dependent on a number of machine, geometry and process parameters. The variability of these parameters affects the manufacturing drastically and therefore standardized processes and harmonized methodologies need to be developed to characterize the technology for end use applications and enable the technology for manufacturing. This research proposes a composite methodology integrating Taguchi Design of Experiments, multi-objective optimization and statistical process control, to optimize the manufacturing process and fulfil multiple requirements imposed to an arbitrary geometry. The proposed methodology aims to characterize AM technology depending upon manufacturing process variables as well as to perform a comparative assessment of three AM technologies (Selective Laser Sintering, Laser Stereolithography and Polyjet). Results indicate that only one machine, laser-based Stereolithography, was feasible to fulfil simultaneously macro and micro level geometrical requirements but mechanical properties were not at required level. Future research will study a single AM system at the time to characterize AM machine technical capabilities and stimulate pre-normative initiatives of the technology for end use applications.

  12. CASE STUDY OF THE OPTIMIZING THE AUTOMOTIVE MANUFACTURING SYSTEMS EFFICIENCY VIA APPLYING NEW METHOD OF SCHEDULING

    Directory of Open Access Journals (Sweden)

    Seyedehfarzaneh Nojabaei

    2014-01-01

    Full Text Available Efficiency is becoming a pivotal aspect in each manufacturing system and scheduling plays a crucial role in sustaining it. The applicability of distributed computing to coordinate and execute jobs has been investigated in the past literature. Moreover, it is significant that even for sensitive industrial systems the only criterion of allocating jobs to appropriate machines is the FIFO policy. On the other flip, many researchers are of the opinion that the main reason behind failing to provide fairness in distributed systems is considering the only criterion of time stamp to judge upon and form the queue of jobs with the aim of allocating those jobs to the machines. In order to increase the efficiency of sensitive industrial system, this study takes into consideration of three criteria of each job including priority, time action and time stamp. The methodology adopted by this study is definition of job scheduler and positioning jobs in temporary queue and sorting via developing bubble sort. In sorting algorithm criterion of priority, time action should be considered besides time stamp to recognize the tense jobs for processing earlier. To evaluate this algorithm first a numerical test case (simulation is programmed and then the case study performing in order to optimize efficiency of applying this method in real manufacturing system. Eventually the results of this study provided evidence on that the rate of efficiency is increased.

    2015-01-01

    openEHR is a flexible and scalable modeling methodology for clinical information and has been widely adopted in Europe and Australia. Due to the reasons of differences in clinical process and management, there are few research projects involving openEHR in China. To investigate the feasibility of openEHR methodology for clinical information modelling in China, this paper carries out a case study to apply openEHR archetypes to Clinical Data Repository (CDR) in a Chinese hospital. The results show that a set of 26 archetypes are found to cover all the concepts used in the CDR. Of all these, 9 (34.6%) are reused without change, 10 are modified and/or extended, and 7 are newly defined. The reasons for modification, extension and newly definition have been discussed, including granularity of archetype, metadata-level versus data-level modelling, and the representation of relationships between archetypes.

    2014-03-01

    In land evaluation science, a standard data set is obtained for each land unit to determine the land capability class for various uses, such as different farming systems, forestry, or the conservation or suitability of a specific crop. In this study, we used mathematical decision theory (MDT) methods to address this task. Mathematical decision theory has been used in areas such as management, finance, industrial design, rural development, the environment, and projects for future welfare to study quality and aptness problems using several criteria. We also review MDT applications in soil science and discuss the suitability of MDT methods for dealing simultaneously with a number of problems. The aim of the work was to show how MDT can be used to obtain a valid land quality index and to compare this with a traditional land capability method. Therefore, an additive classification method was applied to obtain a land quality index for 122 land units that were compiled for a case study of the Community of Madrid, Spain, and the results were compared with a previously assigned land capability class using traditional methods based on the minimum requirements for land attributes.

    Overmeyer, Austin D.; Tanner, Philip E.; Martin, Preston B.; Commo, Sean A.

    2015-01-01

    The application of statistical Design of Experiments (DOE) to helicopter wind tunnel testing was explored during two powered rotor wind tunnel entries during the summers of 2012 and 2013. These tests were performed jointly by the U.S. Army Aviation Development Directorate Joint Research Program Office and NASA Rotary Wing Project Office, currently the Revolutionary Vertical Lift Project, at NASA Langley Research Center located in Hampton, Virginia. Both entries were conducted in the 14- by 22-Foot Subsonic Tunnel with a small portion of the overall tests devoted to developing case studies of the DOE approach as it applies to powered rotor testing. A 16-47 times reduction in the number of data points required was estimated by comparing the DOE approach to conventional testing methods. The average error for the DOE surface response model for the OH-58F test was 0.95 percent and 4.06 percent for drag and download, respectively. The DOE surface response model of the Active Flow Control test captured the drag within 4.1 percent of measured data. The operational differences between the two testing approaches are identified, but did not prevent the safe operation of the powered rotor model throughout the DOE test matrices.

    User-centred design (UCD) is a type of user interface design in which the needs and desires of users are taken into account at each stage of the design process for a service or product; often for software applications and websites. Its goal is to facilitate the design of software that is both useful and easy to use. To achieve this, you must characterise users' requirements, design suitable interactions to meet their needs, and test your designs using prototypes and real life scenarios.For bioinformatics, there is little practical information available regarding how to carry out UCD in practice. To address this we describe a complete, multi-stage UCD process used for creating a new bioinformatics resource for integrating enzyme information, called the Enzyme Portal (http://www.ebi.ac.uk/enzymeportal). This freely-available service mines and displays data about proteins with enzymatic activity from public repositories via a single search, and includes biochemical reactions, biological pathways, small molecule chemistry, disease information, 3D protein structures and relevant scientific literature.We employed several UCD techniques, including: persona development, interviews, 'canvas sort' card sorting, user workflows, usability testing and others. Our hope is that this case study will motivate the reader to apply similar UCD approaches to their own software design for bioinformatics. Indeed, we found the benefits included more effective decision-making for design ideas and technologies; enhanced team-working and communication; cost effectiveness; and ultimately a service that more closely meets the needs of our target audience.

    2016-01-01

    For more than 70 years, Piaget's class-inclusion task (given, e.g., five asters and three tulips, the child is asked whether "there are more asters or more flowers") has been the object of experimental investigation. Inclusion is of considerable importance for cognitive science as it is a key concept for logical operations and knowledge representation. It is shown that the question can be characterised by a kind of privative ambiguity which is at the source of the younger children's answer, "more asters". A relevance-theoretic explanation of children's interpretation of the question and of the subsequent responses is expounded. This account can explain the effect of all the factors that are known to influence performance (e.g., role of collections, counting, typicality, qualification, syntax, etc.), a review of which is presented. It is further tested experimentally. The development of performance is explained on the basis of the way children disambiguate the question. This study exemplifies the two ways in which pragmatic analysis is pertinent to the study of children's (as well as adults') reasoning and judgement, namely in explaining and predicting participants' comprehension of the statements and questions, and in taking into account attribution processes that occur in the experimental setting.

    2014-05-01

    Within the context of flood forecasting, assessment of predictive uncertainty has become a necessity for most of the modelling studies in operational hydrology. There are several uncertainty analysis and/or prediction methods available in the literature; however, most of them rely on normality and homoscedasticity assumptions for model residuals occurring in reproducing the observed data. This study focuses on a statistical method analyzing model residuals without having any assumptions and based on a clustering approach: Uncertainty Estimation based on local Errors and Clustering (UNEEC). The aim of this work is to provide a comprehensive evaluation of the UNEEC method's performance in view of clustering approach employed within its methodology. This is done by analyzing normality of model residuals and comparing uncertainty analysis results (for 50% and 90% confidence level) with those obtained from uniform interval and quantile regression methods. An important part of the basis by which the methods are compared is analysis of data clusters representing different hydrometeorological conditions. The validation measures used are PICP, MPI, ARIL and NUE where necessary. A new validation measure linking prediction interval to the (hydrological) model quality - weighted mean prediction interval (WMPI) - is also proposed for comparing the methods more effectively. The case study is Brue catchment, located in the South West of England. A different parametrization of the method than its previous application in Shrestha and Solomatine (2008) is used, i.e. past error values in addition to discharge and effective rainfall is considered. The results show that UNEEC's notable characteristic in its methodology, i.e. applying clustering to data of predictors upon which catchment behaviour information is encapsulated, contributes increased accuracy of the method's results for varying flow conditions. Besides, classifying data so that extreme flow events are individually

For the reason of its pollution, oil-dependent industries, hot and humid weather, having a long hot and dusty season, the citizens have been encouraged to travel to other areas with better climate. Therefore, it is necessary to locate a place with appropriate climate in the province. In this study, we use the descriptive combination and analytical method and this research is applied. We aim to examine three patterns: the final level pattern walkway areas of major cities, Robert pattern and standard distance pattern. Results show that, because of the long distance between Ahvaz and Malaga, the above-mentioned models could not determine Ahvaz walkway field.2- Theoretical basesThe Tourism has expressed as the specific spatial patterns. One of them is spatial patterns of urban tourism. Urban areas are important tourism places because they have historical and cultural attractions. The major cities have many diverse attractions, including museums, monuments, theaters, sports stadiums, parks, toy city, Shopping centers, and places of historical and architectural sites of important events with famous people. Moreover, if the tourist attractions are located in rural areas, urban movement supports the objective location.To examine the influence of large urban parks, three methods are used that are: A - The final model of the metropolitan parkB - Robert patternC - Standard distance model3– DiscussionThere are three different variations of climate in Khuzestan province: desert climate, semi desert climate and mountainous climate that are suitable for tourism. Ahvaz city has taken in desert climatology; therefore, there is a need for amusement places at mountainous climates. As map

    Full Text Available In power transformers, locating the partial discharge (PD source is as important as identifying it. Acoustic Emission (AE sensing offers a good solution for both PD detection and PD source location identification. In this paper the principle of the AE technique, along with in-situ findings of the online acoustic emission signals captured from partial discharges on a number of Generator Transformers (GT, is discussed. Of the two cases discussed, the first deals with Acoustic Emission Partial Discharge (AEPD tests on two identical transformers, and the second deals with the AEPD measurement of a transformer carried out on different occasions (years. These transformers are from a hydropower station and a thermal power station in India. Tests conducted in identical transformers give the provision for comparing AE signal amplitudes from the two transformers. These case studies also help in comprehending the efficacy of integrating Dissolved Gas is (DGA data with AEPD test results in detecting and locating the PD source.

    Directory of Open Access Journals (Sweden)

    D. Viveros-Melo

    2017-02-01

    Full Text Available Case-based reasoning (CBR is a process used for computer processing that tries to mimic the behavior of a human expert in making decisions regarding a subject and learn from the experience of past cases. CBR has demonstrated to be appropriate for working with unstructured domains data or difficult knowledge acquisition situations, such as medical diagnosis, where it is possible to identify diseases such as: cancer diagnosis, epilepsy prediction and appendicitis diagnosis. Some of the trends that may be developed for CBR in the health science are oriented to reduce the number of features in highly dimensional data. An important contribution may be the estimation of probabilities of belonging to each class for new cases. In this paper, in order to adequately represent the database and to avoid the inconveniences caused by the high dimensionality, noise and redundancy, a number of algorithms are used in the preprocessing stage for performing both variable selection and dimension reduction procedures. Also, a comparison of the performance of some representative multi-class classifiers is carried out to identify the most effective one to include within a CBR scheme. Particularly, four classification techniques and two reduction techniques are employed to make a comparative study of multiclass classifiers on CBR

    This study applied artificial intelligence to help nurses address problems and receive instructions through information technology. Nurses make diagnoses according to professional knowledge, clinical experience, and even instinct. Without comprehensive knowledge and thinking, diagnostic accuracy can be compromised and decisions may be delayed. We used a back-propagation neural network and other tools for data mining and statistical analysis. We further compared the prediction accuracy of the previous methods with an adaptive-network-based fuzzy inference system and the back-propagation neural network, identifying differences in the questions and in nurse satisfaction levels before and after using the nursing information system. This study investigated the use of artificial intelligence to generate nursing diagnoses. The percentage of agreement between diagnoses suggested by the information system and those made by nurses was as much as 87 percent. When patients are hospitalized, we can calculate the probability of various nursing diagnoses based on certain characteristics.

    2016-08-01

    Critical discourse analysis (CDA) is a promising methodology for policy research in nursing. As a critical theoretical methodology, researchers use CDA to analyze social practices and language use in policies to examine whether such policies may promote or impede social transformation. Despite the widespread use of CDA in other disciplines such as education and sociology, nursing policy research employing CDA methodology is sparse. To advance CDA use in nursing science, it is important to outline the overall research strategies and describe the steps of CDA in policy research. This article describes, using exemplar case studies, how nursing and health policy researchers can employ CDA as a methodology. Three case studies are provided to discuss the application of CDA research methodologies in nursing policy research: (a) implementation of preconception care policies in the Zhejiang province of China, (b) formation and enactment of statewide asthma policy in Washington state of the United States, and (c) organizational implementation of employee antibullying policies in hospital systems in the Pacific Northwest of the United States. Each exemplar details how CDA guided the examination of policy within specific contexts and social practices. The variations of the CDA approaches in the three exemplars demonstrated the flexibilities and potentials for conducting policy research grounded in CDA. CDA provides novel insights for nurse researchers examining health policy formation, enactment, and implementation.

    Full Text Available The strategic planning is an important management tool in the corporate scenario and shall not be restricted to big Companies. However, this kind of planning process in small business may need special adaptations due to their own characteristics. This paper aims to identify and adapt the existent models of strategic planning to the scenario of a small business in the fitness area. Initially, it is accomplished a comparative study among models of different authors to identify theirs phases and activities. Then, it is defined which of these phases and activities should be present in a model that will be utilized in a small business. That model was applied to a Pilates studio; it involves the establishment of an organizational identity, an environmental analysis as well as the definition of strategic goals, strategies and actions to reach them. Finally, benefits to the organization could be identified, as well as hurdles in the implementation of the tool.

    The detailed characterization of fractured media in the shallow subsurface is becoming important. The detailed knowledge of the fracture network is mandatory in any hydrogeological model to constrain the potential pathways for water circulation. The geophysical methodolgies can provide a detailed image of the fractured rock and also the 3D distribution of physical properties. Two case studies are discussed in this work. The characterization of fractures in a waste disposal site and, the design and construction of a subway tunnel. In the first case, a multiseismic experiment was carried out in an old abandoned uranium mine. 2D and 3D seismic experiments including VSP, surface seismic reflection and travel time seismic tomography provided a 3D image of the internal structure of a granitic massif for hydrogeological studies of the preferred paths for the migration of contaminants. The tectonic stability of the site was also addressed by means of seismic measurements. The joint interpretation of all the available data enabled the interpretation of the low velocity anomalies in the 3D seismic tomography image as the fragile fractures and the alteration associated to them. A 3D image of the geometry of the heterogeneous weathered surface layer was also obtained. This surface is controlled by the complex network of faults and dykes observed in the area. The second case study involves 2D and 3D seismic experiments to aid the horizontal drilling of tunnels for a new subway line in Barcelona (Spain). Seismic data acquisition in a densely populated city is very difficult. The street layout determines the geometry of the acquisition experiments. The instrumentation can not always be located on the surface projection of the tunnel trace, therefore, pseudo 3D acquisition is required, deploying the instrumentation were it is possible. Furthermore, the shallow subsurface features extremely heterogeneous "weathered" layer of variable thickness (building fundations, sewage system

    Low Impact Development (LID) has been developed since the end of 1990s. Lots of successful experience based on this new technology have been made. Taiwan Executive Yuan is conducting a six-year (2014~2019) program "Integrated River Basin Management Plan" applying LID to build sponge cities. Construction and Planning Agency, Ministry of the Interior is editing the manual of LID technology for Taiwan. However, since the hydrological environments, physiographic conditions, climates, the strength and frequency of disasters in Taiwan are different from that in America, this study takes the first laboratory experiment and model simulation to evaluate the efficiency of application of LID in Taiwan.LID Facilities includes porous pavement, rain garden, green roof, tree box filter facilities and so on, and in this study, porous pavement is taken as an example for discussion. In the part of laboratory experiments, the sand box experiments is designed to operate with the specified rainfall return period calculated by Horton formula and rainfall characteristics of Taipei. Then the outflow hydrograph in each designed rainfall of specified return period can be evaluated. As for model simulation, this study constructs LID simulation elements by SWMM model and tests the suitability for simulation of the outflow hydrograph obtained from experiments, and definitely quantifies the efficiency of water retention and flood reduction of porous pavement. The results fits well with the experimental observation data with less than 10% error of pick flow. It suggests that, with LID simulation elements constructed in this study, the efficiency of LID in actual on-site application can be evaluated.The results shows that porous pavement is able to delay arrival time of pick about 5% ~10% and reduce the pick flow about 5%~20%, and hold the ability of near 3~5% water retention. It proves that application of LID can retain water and reduce flood in Taiwan.

    2001-01-01

    Concern over the fate of plant and animal species throughout the world has accelerated over recent decades. Habitat loss is considered the main culprit in reducing many species' abundance and range, leading to numerous efforts to plan and manage habitat preservation. Our work uses Geographic Information Systems (GIS) data and modeling to define a spatially explicit analysis of habitat value, using the San Joaquin Kit Fox (Vulpes macrotis mutica) of California (USA) as an example. Over the last 30 years, many field studies and surveys have enhanced our knowledge of the life history, behavior, and needs of the kit fox, which has been proposed as an umbrella or indicator species for grassland habitat in the San Joaquin Valley of California. There has yet been no attempt to convert much of this field knowledge into a model of spatial habitat value useful for planning purposes. This is a significant omission given the importance and visibility of the imperiled kit fox and increasing trends toward spatially explicit modeling and planning. In this paper we apply data from northern California to derive a small-cell GIS raster of habitat value for the kit fox that incorporates both intrinsic habitat quality and neighborhood context, as well the effects of barriers such as roads. Such a product is a useful basis for assessing the presence and amounts of good (and poor) quality habitat and for eventually constructing GIS representations of viable animal territories that could be included in future reserves. ?? 2001 Elsevier Science B.V.

    2016-06-01

    In this paper we present the results of the development of a Web-based archiving and documenting system aimed to the management of multisource and multitemporal data related to cultural heritage. As case study we selected the building complex of Villa Revedin Bolasco in Castefranco Veneto (Treviso, Italy) and its park. Buildings and park were built in XIX century after several restorations of the original XIV century area. The data management system relies on a geodatabase framework, in which different kinds of datasets were stored. More specifically, the geodatabase elements consist of historical information, documents, descriptions of artistic characteristics of the building and the park, in the form of text and images. In addition, we used also floorplans, sections and views of the outer facades of the building extracted by a TLS-based 3D model of the whole Villa. In order to manage and explore these rich dataset, we developed a geodatabase using PostgreSQL and PostGIS as spatial plugin. The Web-GIS platform, based on HTML5 and PHP programming languages, implements the NASA Web World Wind virtual globe, a 3D virtual globe we used to enable the navigation and interactive exploration of the park. Furthermore, through a specific timeline function, the user can explore the historical evolution of the building complex.

    Within recent years, energy policies have imposed a number of targets at European and national level for rational use of energy (RUE), renewable energy sources (RES) and related CO{sub 2} reductions. As a result, a wide variety of policy instruments is currently implemented and hence the question arises: how can these instruments be designed in a way to reach the maximum policy target with the minimum public money spent? The objective of this paper is to derive a methodology for obtaining efficient policy portfolios promoting sustainable energy systems depending on the policy target and show corresponding results from case studies in Austria, Germany and Poland. The investigations were carried out by application of Invert simulation tool, a computer model developed for simulating the impacts of various promotion schemes for renewable and efficient energy systems. With this tool, the CO{sub 2} reductions and related public expenses have been calculated for various policy mixes. In the building-related energy sector, it turned out that in all investigated regions support schemes for supply side measures are the most cost-efficient instruments. However, their potential is restricted and for achieving higher levels of CO{sub 2} reduction, promotion of demand side measures is indispensable. The paper shows that for a comprehensive comparison of policy portfolios, there are always two dimensions to be considered: efficiency and effectiveness. The more effective, i.e. the higher the implementation rate of a scheme, the more essential becomes the efficiency criteria. (author)

    Full Text Available For a few years now, the Dipartimento di Storie e Metodi per la Conservazione dei Beni Culturali of the Alma Mater Studiorum Università di Bologna (sede di Ravenna has been creating a Diagnostic Laboratory for the study on the “system: cultural heritage/conservation environment”. In the present paper the results of different surveys concerning the use of colorimetry on different typologies of art works are reported: graphic documents (fig. 1; oil painting on board and canvas (fig. 2; wall painting (fig. 3; stony materials consolidated with ethyl silicate (fig. 4. Measurements of the chromatic parameters, according to the CIE L*a*b* chromaticity diagram and to the UNI 8941 Standard Coloured surfaces, were carried out with the spectrophotometric colorimeter Minolta CM-2600D model. The reference measurements (targets were carried out on every typology of works. Such targets, recorded on the tool or in the computer, could be considered in order to draw a comparison in time on the same studied surface. It is then possible to check the trend of the chromatic alteration as an effect of interaction of the environment of location-conservation with the art work and, then to determine the causes, i.e the environmental operating-factors. The measurements of the chromatic parameters for graphic documents and for wall paintings have also allowed us to establish if the modifications, caused by an inappropriate environment, must be linked to irreversible or reversible effects and, then, with the possibility of being removed. As regards wall paintings, the respect of the “noble patina” was showed, as established by the Card of Restoration, by means of the measurement of the + b* parameters (yellow degree. The studies on stony materials aimed at the evaluation of the chromatic alterations of the art works previously consolidated with various products based on ethyl silicates: different results were reached according to the different degree of stone

    The Amdoun region is characterized by a high degree of karstification due to the climate impact (±1500 mm year-1) and the development of fracture network. Survey using electrical resistivity tomography (ERT) is deployed to provide a cost-effective characterization of the subsurface karst environments. A total of seven ERT profiles with lengths of 315 m were evaluated at the Béja governorate (NW Tunisia). The area represents a small syncline of Boudabbous limestone rocks (Lower Eocene), which is covered by a thin layer of clay. In this study, an ERT survey was conducted to examine the spatial distribution and shape of underground cavities in the karst area in Jebel Sabah anticline and Aïn Sallem-Zahret Medien syncline. In this study, geological, hydro-geological and electrical resistivity tomography (ERT) methods were applied to determine the geometry of the perched aquifer in the Amdoun region (NW Tunisia). The area is characterized by fractured and karstic limestone aquifer of Late Cretaceous (Abiod Fm.) and Lower Eocene (Boudabbous Fm.). The aquifers have a karstic functioning and drain aquifers of economical interest, despite some wells exploiting them. Seven resistivity profiles were conducted along the survey area at three sites. The orientation, extension and the degree of inclination of those profiles are shown in the location map. The correct resistivity data were interpreted using Earth Imager 2D software. The results of the interpreted geo-electrical sections showed that the resistivity of the carbonate aquifer varied between 2.5 to over 5794 Ωm. The thickness of the perched aquifer ranged from 15 to 50 m, while its depth from the surface lies between 10 and 60 m. The ERT not only provided precise near surface information, but was also very useful for establishing the 3D geometry and the position of several potential cavities and karts. The results show the presence of small to large isolated cavities at various depths. The low resistivity of cavities

    Full Text Available South African National Parks (SANParks has a history of formal and informal natural resource use that is characterised by polarised views on national conservation interests and benefits to communities. Current efforts aim to determine the sustainability of existing resource use in parks and to formalise these activities through the development of resource use protocols. The resource use policy of SANParks outlines principles for sustainable resource use, including greater involvement of local communities in management of protected areas and an adaptive management approach to determining sustainable use levels. This paper examines three case studies on plant use in national parks with regard to the development of criteria and indicators for monitoring resource use, and the role of thresholds of potential concern in measuring effectiveness of managing for sustainable use levels. Opportunities and challenges for resource use management are identified. Findings show that platforms for discussion and knowledge sharing, including research committees and community associations, are critical to building relationships, trust and a shared vision of sustainable resource use between stakeholders. However, additional capacity building is needed to enable local community structures to manage internal social conflicts and jealousy, and to participate fully in monitoring efforts. Long-term monitoring is essential for developing flexible harvest prescriptions for plant use, but this is a time-consuming and resource-intensive exercise. Flexible management strategies are difficult to implement and sometimes command-and-control measures are necessary to protect rare or endangered species. A holistic approach that considers resource use in national parks as a complement to broader community development initiatives offers a way forward.Conservation implications: There is no blueprint for the development of sustainable resource use systems and resource use is often

    Full Text Available Concurrent engineering (CE is one of the widest known techniques for simultaneous planning of product and process design. In concurrent engineering, design processes are often complicated with multiple conflicting criteria and discrete sets of feasible alternatives. Thus multi-criteria decision making (MCDM techniques are integrated into CE to perform concurrent design. This paper proposes a design framework governed by MCDM technique, which are in conflict in the sense of competing for common resources to achieve variously different performance objectives such as financial, functional, environmental, etc. The Pareto MCDM model is applied to polyethylene pipe concurrent design governed by four criteria to determine the best alternative design to Pareto-compromise design.

    NL Agency is supporting WWF and the Secretariat of the Roundtable on Sustainable Biofuels (RSB) with the development of a certification module for biofuels with a low risk of indirect land use change (ILUC), the Low Indirect Impact Biofuel (LIIB) methodology (www.LIIBmethodology.org). The LIIB methodology was developed to certify that biomass feedstock for biofuels has been produced with a low risk of indirect impacts. It is designed as an independent module that can be added to biofuel policies and existing certification systems for sustainable biofuel and/or feedstock production, such as the RSB Standard, RSPO or NTA8080. It presents detailed ILUC mitigation approaches for four different solution types field-tested and audited in international pilots. Within the Global Sustainable Biomass programme and the Sustainable Biomass Import programme, coordinated by NL Agency, three projects are working on sustainable jatropha in Tanzania. Ecofys has been commissioned by NL Agency to contribute to the further development of the LIIB methodology by applying it to these three jatropha projects in Tanzania. All three projects located in the North of Tanzania, address sustainability in one way or another, but focus on the direct effects of jatropha cultivation and use. Interestingly, they nevertheless seem to apply different methods that could also minimise negative indirect impacts, including ILUC. Bioenergy feedstock production can have unintended consequences well outside the boundary of production operations. These are indirect impacts, which cannot be directly attributed to a particular operation. The most cited indirect impacts are ILUC and food/feed commodity price increases (an indirect impact on food security). ILUC can occur when existing cropland is used to cover the feedstock demand of additional biofuel production. When this displaces the previous use of the land (e.g. food production) this can lead to expansion of land use to new areas (e.g. deforestation) when

    Alvarez-Galvez, Javier

    2016-03-01

    Studies assume that socioeconomic status determines individuals' states of health, but how does health determine socioeconomic status? And how does this association vary depending on contextual differences? To answer this question, our study uses an additive Bayesian Networks model to explain the interrelationships between health and socioeconomic determinants using complex and messy data. This model has been used to find the most probable structure in a network to describe the interdependence of these factors in five European welfare state regimes. The advantage of this study is that it offers a specific picture to describe the complex interrelationship between socioeconomic determinants and health, producing a network that is controlled by socio-demographic factors such as gender and age. The present work provides a general framework to describe and understand the complex association between socioeconomic determinants and health.

    Full Text Available Introduction : All cells in the human body are exposed to reactive oxygen species (ROS, which disturb the metabolic reactions in the organism. The antioxidant system in the human body consists of enzymatic and non-enzymatic mechanisms, among which vitamins A, C, and E play a major role. The aim of the study was to evaluate the supply of vitamins A, C, and E from daily food rations (DFR in postmenopausal women with metabolic syndrome (MS in relation to current nutrition standards. Material and methods: The study involved 184 women with MS, aged 45-68 years (mean 57.38 ±8.17 years. The control group comprised 90 women, aged 41-65 years (mean 57.48 ±5.79 years without MS. The food intake was assessed using 24-hour dietary recalls. Results: The evaluation of intake of vitamins measured with daily food rations (DFR demonstrated that the optimal level of 90-110% according to standards was achieved only in 3.62% of women with metabolic syndrome for vitamin A, in 8.88% for vitamin C, and in 11.41% for vitamin E, which was significantly less often found than in the control group (p < 0.001. Conclusions : Women with MS are characterised by diversified intake of vitamins A, C and E, and a subgroup of this patients present low level of antioxidant vitamins intake. Supplementation with antioxidant vitamins should be prescribed individually to postmenopausal women with MS.

    Community-based participatory research (CBPR) is being used increasingly to address health disparities and complex health issues. The authors propose that CBPR can benefit from a systems science framework to represent the complex and dynamic characteristics of a community and identify intervention points and potential "tipping points." Systems science refers to a field of study that posits a holistic framework that is focused on component parts of a system in the context of relationships with each other and with other systems. Systems thinking tools can assist in intervention planning by allowing all CBPR stakeholders to visualize how community factors are interrelated and by potentially identifying the most salient intervention points. To demonstrate the potential utility of systems science tools in CBPR, the authors show the use of causal loop diagrams by a community coalition engaged in CBPR activities regarding youth drinking reduction and prevention.

    In some communities, local government and non-profit entities have funds to purchase and renovate distressed, foreclosed homes for resale in the affordable housing market. Numerous opportunities to improve whole house energy efficiency are inherent in these comprehensive renovations. BA-PIRC worked together in a multiyear field study making recommendations in individual homes, meanwhile compiling improvement costs, projected energy savings, practical challenges, and labor force factors surrounding common energy-related renovation measures. The field study, Phase 1 of this research, resulted in a set of best practices appropriate to the current labor pool and market conditions in central Florida to achieve projected annual energy savings of 15%-30% and higher. This case study describes Phase 2 of the work where researchers worked with a local government partner to implement and refine the "current best practices". A simulation study was conducted to characterize savings potential under three sets of conditions representing varying replacement needs for energy-related equipment and envelope components. The three scenarios apply readily to the general remodeling industry as for renovation of foreclosed homes for the affordable housing market.

    Full Text Available Electronics industry as an industry with high added value and television production industry especially as one of its pillars play an important role in the economy of each country. Therefore, the aim study of this paper is to illustrate how, using a combined QFD-TOPSIS model, organizations are able to their design product in accordance with requirements of consumers with a case study in Sum Service Company. Quality Function Deployment (QFD is one such extremely important quality management tool that is useful in product design and development. Traditionally, QFD rates the Design Requirements (DRs with respect to customer needs and aggregates the rating to get relative importance score of DRs. An increasing number of studies emphasize on the need to incorporate additional factors, such as cost and environmental impact, while calculating the relative importance of DRs. However, there is variety of methodologies for driving the relative importance of DRs, when several additional factors are considered. TOPSIS (technique for order preferences by similarity to ideal solution is suggested for the purpose of the research. This research proposes new approach of TOPSIS for considering the rating of DRs with respect to CRs and several additional factors simultaneously. Proposed method is illustrated using by step-by-step procedure. The proposed fuzzy QFDTOPSIS methodology was applied for the Sum Service Company in Iran.

    Mangrove forests are under global pressure. Habitat destruction and degradation persist despite longstanding recognition of the important ecological functions of mangroves. Hence new approaches are needed to help stakeholders and policy-makers achieve sound management that is informed by the best science. Here we explore how the new policy concept of Climate Compatible Development (CCD) can be applied to achieve better outcomes. We use economic valuation approaches to combine socio-economic data, projections of forest cover based on quantitative risk mapping and storyline scenario building exercises to articulate the economic consequences of plausible alternative future scenarios for the mangrove forests of the South Kenya coast, as a case study of relevance to many other areas. Using data from 645 household surveys, 10 focus groups and 74 interviews conducted across four mangrove sites, and combining these with information on fish catches taken at three landing sites, a mangrove carbon trading project and published data allowed us to make a thorough (although still partial) economic valuation of the forests. This gave a current value of the South Coast mangroves of USD 6.5 million, or USD 1166 ha(-1), with 59% of this value on average derived from regulating services. Quantitative risk mapping, projecting recent trends over the next twenty years, suggests a 43% loss of forest cover over that time with 100% loss at the most vulnerable sites. Much of the forest lost between 1992 and 2012 has not been replaced by high value alternative land uses hence restoration of these areas is feasible and may not involve large opportunity costs. We invited thirty eight stakeholders to develop plausible storyline scenarios reflecting Business as Usual (BAU) and CCD - which emphasises sustainable forest conservation and management - in twenty years time, drawing on local and regional expert knowledge of relevant policy, social trends and cultures. Combining these scenarios with

    Full Text Available In the last ten years, the development and implementation of measures to mitigate climate change have become of major importance. In Europe, the residential sector accounts for 27% of the final energy consumption [1], and therefore contributes significantly to CO2 emissions. Roadmaps towards energy-efficient buildings have been proposed [2]. In such a context, the detailed characterization of residential building stocks in terms of age, type of construction, insulation level, energy vector, and of evolution prospects appears to be a useful contribution to the assessment of the impact of implementation of energy policies. In this work, a methodology to develop a tree-structure characterizing a residential building stock is presented in the frame of a bottom-up approach that aims to model and simulate domestic energy use. The methodology is applied to the Belgian case for the current situation and up to 2030 horizon. The potential applications of the developed tool are outlined.

    2015-12-01

    Much literature surrounding medical technology and adherence posits that technology is a mechanism for social control. This assumes that the medical establishment can take away patients' agency. Although power relationships and social control can play a key role, medical technology can also serve as an agentive tool to be utilized. We (1) offer the alternative framework of Actor Network Theory to view medical technology, (2) discuss the literature on medication adherence and technology, (3) delve into the ramifications of looking at adherence as a network and (4) use Digital Pills as a case study of dispersed agency.

    2016-02-01

    The aim of this study is to predict landslide susceptibility caused using the spatial analysis by the application of a statistical methodology based on the GIS. Logistic regression models along with artificial neutral network were applied and validated to analyze landslide susceptibility in Inje, Korea. Landslide occurrence area in the study were identified based on interpretations of optical remote sensing data (Aerial photographs) followed by field surveys. A spatial database considering forest, geophysical, soil and topographic data, was built on the study area using the Geographical Information System (GIS). These factors were analysed using artificial neural network (ANN) and logistic regression models to generate a landslide susceptibility map. The study validates the landslide susceptibility map by comparing them with landslide occurrence areas. The locations of landslide occurrence were divided randomly into a training set (50%) and a test set (50%). A training set analyse the landslide susceptibility map using the artificial network along with logistic regression models, and a test set was retained to validate the prediction map. The validation results revealed that the artificial neural network model (with an accuracy of 80.10%) was better at predicting landslides than the logistic regression model (with an accuracy of 77.05%). Of the weights used in the artificial neural network model, `slope' yielded the highest weight value (1.330), and `aspect' yielded the lowest value (1.000). This research applied two statistical analysis methods in a GIS and compared their results. Based on the findings, we were able to derive a more effective method for analyzing landslide susceptibility.

    In a recent interdisciplinary study, Das et al. have attempted to trace the homeland of Ashkenazi Jews and of their historical language, Yiddish (Das et al. 2016 Localizing Ashkenazic Jews to Primeval Villages in the Ancient Iranian Lands of Ashkenaz. Genome Biol Evol. 8:1132-1149). Das et al. applied the geographic population structure (GPS) method to autosomal genotyping data and inferred geographic coordinates of populations supposedly ancestral to Ashkenazi Jews, placing them in Eastern Turkey. They argued that this unexpected genetic result goes against the widely accepted notion of Ashkenazi origin in the Levant, and speculated that Yiddish was originally a Slavic language strongly influenced by Iranian and Turkic languages, and later remodeled completely under Germanic influence. In our view, there are major conceptual problems with both the genetic and linguistic parts of the work. We argue that GPS is a provenancing tool suited to inferring the geographic region where a modern and recently unadmixed genome is most likely to arise, but is hardly suitable for admixed populations and for tracing ancestry up to 1,000 years before present, as its authors have previously claimed. Moreover, all methods of historical linguistics concur that Yiddish is a Germanic language, with no reliable evidence for Slavic, Iranian, or Turkic substrata.

  14. Geological-geophysical techniques applied to urban planning in karst hazardous areas. Case study of Zaragoza, NE Spain

    Pueyo Anchuela, O.; Soriano, A.; Casas Sainz, A.; Pocoví Juan, A.

    2009-12-01

    Industrial and urban growth must deal in some settings with geological hazards. In the last 50 years, the city of Zaragoza (NE Spain) has developed an increase of its urbanized area in a progression several orders higher than expected from its population increase. This fast growth has affected several areas around the city that were not usually used for construction. Maps of the Zaragoza city area at the end of the XIXth century and beginning of the XXth reveal the presence of karst hazards in several zones that can be observed in more modern data, as aerial photographs taken during a period ranging from 1927 to present. The urban and industrial development has covered many of these hazardous zones, even though potential risks were known. The origins of the karst problems are related to the solution of evaporites (mainly gypsum, glauberite and halite) that represent the Miocene substratum of the Zaragoza area underlying the Quaternary terraces and pediments related to the Ebro River and its tributaries. Historical data show the persistence of subsidence foci during long periods of time while in recent urbanized areas this stability is not shared, observing the increase of activity and/or radius affection in short periods of time after building over. These problems can be related to two factors: i) urban development over hazardous areas can increase the karst activity and ii) the affection radius is not properly established with the commonly applied methods. One way to develop these detailed maps can be related to the geophysical approach. The applied geophysical routine, dependent on the characteristics of the surveyed area, is based on potential geophysical techniques (magnetometry and gravimetry) and others related to the application of induced fields (EM and GPR). The obtained results can be related to more straightforward criteria as the detection of cavities in the subsoil and indirect indicators related to the long-term activity of the subsidence areas

    Within the NASA DEVELOP National Program, teams conduct rapid prototype and feasibility projects, applying NASA Earth Observations to a broad range of problems in diverse focus areas, including water resources, agriculture, disaster management, and ecological forecasting, with the goal of assisting partner organizations in their decision making processes. Projects vary in scope, design, and satellite data utilized. As a result, there is no "fixed" set of indicators that encompasses all relevant impacts of all projects. Rather, a flexible toolkit of both shared indicators and individualized approaches is needed to capture the diverse outcomes of these projects, while still allowing for comparability of the projects. This has been done through the creation of pre- and post-project partner assessments that capture partner needs, capabilities, and expectations. This provides both baseline data and an overview of project impacts on partners. Selected projects are then individually assessed in greater detail through partner follow-ups and research into the quantification of project impacts utilizing interdisciplinary approaches to fit each project. This process is discussed through three examples of project impact assessments that draw from varied discipline approaches including cost benefit analysis and ecosystem services.

  16. Apply ETAS in Earthquake Early Warning - A case study of M6.0 South Napa Earthquake

    Science.gov (United States)

    Yin, L.; Heaton, T. H.

    2014-12-01

    Earthquake Early Warning (EEW) is a trade-off between time and accuracy. We aim to increase the alerting time without loosing its reliability. This can be achieved by using prior information to classify a pick to be a true or false event, then issue alerts immediately after the first trigger. Since earthquakes cluster in time and location, potential aftershock occurrences can be predicted using the Epidemic-Type Aftershock Sequence Model (ETAS). We show that by applying the prior information provided by ETAS in the Bayesian updating process of EEW, we can significantly improve the alerting time. As an example, the epicenter estimation for the aftershock events from the M6.0 South Napa Earthquake is performed using ETAS to illustrate the accuracy of aftershock prediction. For instance, in an aftershock sequence, the most triggers at the closest stations will turn out to be real earthquake. As a result, during the aftershock sequence of the South Napa earthquake, warnings can be issued after observations of only one or two stations.

    Full Text Available George, a 23-year-old Greek student, was referred by a psychiatrist for treatment to a University Counseling Centre in Athens. He was diagnosed with social anxiety disorder and specific phobia situational type. He was complaining of panic attacks and severe symptoms of anxiety. These symptoms were triggered when in certain social situations and also when travelling by plane, driving a car and visiting tall buildings or high places. His symptoms lead him to avoid finding himself in such situations, to the point that it had affected his daily life. George was diagnosed with social anxiety disorder and with specific phobia, situational type (in this case acrophobia and was given 20 individual sessions of cognitive-behavior therapy. Following therapy, and follow-up occurring one month post treatment, George no longer met the criteria for social phobia and symptoms leading to acrophobia were reduced. He demonstrated improvements in many areas including driving a car in and out of Athens and visiting tall buildings.

    Upham, Paul [Tyndall Centre Manchester and Manchester Institute of Innovation Research, Pariser Building, The University of Manchester, Manchester M60 1QD (United Kingdom)

    2009-11-15

    To date, studies of energy siting controversy and of environmental psychology have barely informed one another, despite the environmental-behaviour literature potentially having considerable relevance to understanding public opposition to energy projects. This paper points towards this relevance, using the example of a longitudinal study of public objections to a 21.5 MWe bioenergy gasifier proposed for Winkleigh in Devon, England. Local opinion surveys in 2004 and 2007 showed that public opposition to the proposed gasifier remained strong but also revealed some statistically significant change and correlations of wider interest. In the context of the environmental psychology literature, the dominant model of contextualised values, intention and behaviour, as well as other psychological approaches, are found to be helpful, both for making sense of the results and for informing a psychological research agenda on public objection to new energy infrastructure.

    A forest fire risk map is a basic element for planning and protecting forested areas. The main goal of this study was to develop a statistical model for preparing a forest fire risk map using GIS. Such model is based on assigning weights to nine variables divided into two classes: physical factors of the site (terrain slope, land-use/occupation, proximity to roads, terrain orientation, and altitude) and climatic factors (precipitation, temperature, water deficit, and evapotranspiration). In regions where the climate is different from the conditions of this study, the model will require an adjustment of the variables weights according to the local climate. The study area, Espírito Santo State, exhibited approximately 3.81% low risk, 21.18% moderate risk, 30.10% high risk, 41.50% very high risk, and 3.40% extreme risk of forest fire. The areas classified as high risk, very high and extreme, contemplated a total of 78.92% of heat spots.

    We present a careful study of the thermal degradation effects in the mass spectrum of DL-Valine using a quadrupole mass spectrometer and a time of flight – mass spectrometer. This allows setting the temperature of 95 ± 10 °C as threshold for the sublimation of our solid sample. Based on the assignments for each ionic fragment detected, it is possible to separate the mass peaks in groups, explaining what are the principal bond breaks involved in the specific ionic yield, whose procedure can be extended to other amino acids.

  2. Instruments for assessing the biological diversity applied to socio-economic systems. Case study: Romanian regions of development

    Directory of Open Access Journals (Sweden)

    Ioan Ianoş

    2012-06-01

    Full Text Available When referring to environmental diversity, the components (the variety of ecological systems and species, the genetic diversity, and the heterogeneity of anthropized and anthropic systems vary at different spatial scales. This study proposes a method for assessing the latter component, based on a correlation between its spatial levels and the territorial statistical units. Consequently, Shannon-Wiener's informational entropy index, its associated measure of evenness, and Simpson's measure of dominance are used to characterize three components of the ethno-cultural diversity in Romania: ethnic, religious, and territorial. The results indicate that the three components exhibit lower values than natural systems, suggesting the possibility of assimilating them to young systems, and display a heterogeneous spatial distribution varying in time and across components influenced by administrative and political changes, which seem to control anthropic systems.

    2016-01-01

    DNA barcoding is a fast-developing technique to identify species by using short and standard DNA sequences. Universal selection of DNA barcodes in ferns remains unresolved. In this study, five plastid regions (rbcL, matK, trnH-psbA, trnL-F and rps4-trnS) and eight nuclear regions (ITS, pgiC, gapC, LEAFY, ITS2, IBR3_2, DET1, and SQD1_1) were screened and evaluated in the fern genus Adiantum from China and neighboring areas. Due to low primer universality (matK) and/or the existence of multiple copies (ITS), the commonly used barcodes matK and ITS were not appropriate for Adiantum. The PCR amplification rate was extremely low in all nuclear genes except for IBR3_2. rbcL had the highest PCR amplification rate (94.33%) and sequencing success rate (90.78%), while trnH-psbA had the highest species identification rate (75%). With the consideration of discriminatory power, cost-efficiency and effort, the two-barcode combination of rbcL+ trnH-psbA seems to be the best choice for barcoding Adiantum, and perhaps basal polypod ferns in general. The nuclear IBR3_2 showed 100% PCR amplification success rate in Adiantum, however, it seemed that only diploid species could acquire clean sequences without cloning. With cloning, IBR3_2 can successfully distinguish cryptic species and hybrid species from their related species. Because hybridization and allopolyploidy are common in ferns, we argue for including a selected group of nuclear loci as barcodes, especially via the next-generation sequencing, as it is much more efficient to obtain single-copy nuclear loci without the cloning procedure.

    An Abandoned Mines Advanced Terrain Motion Service was commissioned in the framework of the ESA GMES project Terrafirma to demonstrate the capabilities of Radar Interferometry areas of abondened mining. The Coal Measures form the bedrock for much of the study area in the north east of England. The coalfield has a working history dating back to Roman times with over twenty coal seams mined underground in more recent times. The working of deeper and deeper coal seams led to the need to pump mine water. All underground mining has now ceased, the majority of mines were closed by the 1980's. Over the past decade there has been a program to turn off the mine water pumps and allow groundwater levels to recover Two PSI datasets were created; one from 1995 to 2000 the other from 2002 to 2008. PSI results from the 1990s show nine 'hotspots' of subsidence to the south and a larger area of uplift in the north. The subsidence areas show a strong spatial relationship with areas of past mining. However there is a discrepancy in the timing of PSI motions and that of expected subsidence given the type of workings. It is suspected that the motion relates to material extraction, water extraction and the accommodation of resulting motions along faults. Uplift, as seen in the data from the 2000s, this has been attributed to the recovery of groundwater levels as mine water pumping has ceased. The difference between the 1990s results and thoise form the 2000s is marked; areas which were undergoing subsidence between '95 and '00 are uplifting between '02 and '08. This drastic change is supported by minewater level data which shows that water levels have recovered within this time period, with the resulting increase in hydrostatic pressure accounting for the regional pattern of ground heave.

    The success of new food technologies largely depends on consumers' behavioral responses to the innovation. In Eastern Africa, and Uganda in particular, a technology to process matooke into flour has been introduced with limited success. We measure and apply the Food technology Neophobia Scale (FTNS) to this specific case. This technique has been increasingly used in consumer research to determine consumers' fear for foods produced by novel technologies. Although it has been successful in developed countries, the low number and limited scope of past studies underlines the need for testing its applicability in a developing country context. Data was collected from 209 matooke consumers from Central Uganda. In general, respondents are relatively neophobic towards the new technology, with an average FTNS score of 58.7%, which hampers the success of processed matooke flour. Besides socio-demographic indicators, 'risk perception', 'healthiness' and the 'necessity of technologies' were key factors that influenced consumer's preference of processed matooke flour. Benchmarking the findings against previous FTNS surveys allows to evaluate factor solutions, compare standardized FTNS scores and further lends support for the multidimensionality of the FTNS. Being the first application in a developing country context, this study provides a case for examining food technology neophobia for processed staple crops in various regions and cultures. Nevertheless, research is needed to replicate this method and evaluate the external validity of our findings.

    Fast and nondestructive X-ray fluorescence (XRF) core scanning provides high-resolution element data that are widely used in paleoclimate studies. However, various matrix and specimen effects prevent the use of semiquantitative raw XRF core-scanning intensities for robust paleoenvironmental interpretations. We present here a case study of a 50.8 m-long piston Core MD12-3432 retrieved from the northern South China Sea. The absorption effect of interstitial water is identified as the major source of deviations between XRF core-scanning intensities and measured element concentrations. The existing two calibration methods, i.e., normalized median-scaled calibration (NMS) and multivariate log-ratio calibration (MLC), are tested with this sequence after the application of water absorption correction. The results indicate that an improvement is still required to appropriately correct the influence of downcore changes in interstitial water content in the long sediment core. Consequently, we implement a new polynomial water content correction in NMS and MLC methods, referred as NPS and P_MLC calibrations. Results calibrated by these two improved methods indicate that the influence of downcore water content changes is now appropriately corrected. We therefore recommend either of the two methods to be applied for robust paleoenvironmental interpretations of major elements measured by XRF-scanning in long sediment sequences with significant downcore interstitial water content changes.

  10. The evolution of the paleomagnetic fold test as applied to complex geologic situations, illustrated by a case study from northern Spain

    Weil, Arlo B.; Van der Voo, Rob

    Paleomagnetic results are most useful if the age of the magnetization can be established with respect to the rock age or the age of specific structural or alteration events. The fold test is a particularly powerful tool; not only can it be used to determine whether magnetizations are pre-, syn- or post-folding, but it can also reassure us that structural corrections need (or need not) be applied to a given magnetization. This study traces the evolution of various fold and tilt tests developed in the 50-some years since the classical test of Graham was published. Syn-deformational magnetizations are a very special case, usually characterized as such by an incremental tilt test. In regions where rotations about (near-) vertical axes are to be expected, a strike test is the best tool for determining them. A case study of syn-deformational magnetizations in the Cantabria-Asturias Arc (CAA) of northern Spain is presented, which illustrates the application of the various tilt and strike tests. One ancient post-deformational and two syn-deformational magnetizations have been recorded in CAA Devonian carbonates, each characterized by different optimal (peak) percentages of unfolding in incremental fold tests. The structural corrections required to bring the individual site-mean magnetization directions into alignment can be used to restore the beds to their attitudes at the times when the magnetizations were acquired. Furthermore, these structural corrections provide robust constraints on the kinematics of the deformation phase that is being removed. In the CAA, removal of late-stage folding about steeply inclined fold axes, due to Permian oroclinal bending, restores the belt to its first folding and thrusting configuration, and produces north-south trending cylindrical folds that formed during the Late Carboniferous. The separate deformations, consisting of earlier folding and thrusting and later oroclinal bending, have implications for the final collisional movements

    The crucial importance of the three central OECD principles for quantitative structure-activity relationship (QSAR) model validation is highlighted in a case study of tropospheric degradation of volatile organic compounds (VOCs) by OH, applied to two CADASTER chemical classes (PBDEs and (benzo-)triazoles). The application of any QSAR model to chemicals without experimental data largely depends on model reproducibility by the user. The reproducibility of an unambiguous algorithm (OECD Principle 2) is guaranteed by redeveloping MLR models based on both updated version of DRAGON software for molecular descriptors calculation and some freely available online descriptors. The Genetic Algorithm has confirmed its ability to always select the most informative descriptors independently on the input pool of variables. The ability of the GA-selected descriptors to model chemicals not used in model development is verified by three different splittings (random by response, K-ANN and K-means clustering), thus ensuring the external predictivity of the new models, independently of the training/prediction set composition (OECD Principle 5). The relevance of checking the structural applicability domain becomes very evident on comparing the predictions for CADASTER chemicals, using the new models proposed herein, with those obtained by EPI Suite.

    Full Text Available The aim of this case study is to describe the nutrition practices of a female recreational runner (VO2max 48.9 ml·kg-1·min-1 who completed 26 marathons (42.195 km in 26 consecutive days. Information relating to the nutritional intake of female runners during multi-day endurance events is extremely limited, yet the number of people participating year-on-year continues to increase. This case study reports the nutrition intervention, dietary intake, body composition changes and performance in the lead-up and during the 26 days. Prior to undertaking the 26 marathon challenge, three consultations were held between the athlete and a sports nutrition advisor; planning and tailoring the general diet and race-specific strategies to the endurance challenge. During the marathons, the mean energy and fluid intake was 1039.7 ± 207.9 kcal (607.1 – 1453.2 and 2.39 ± 0.35 L (1.98 – 3.19. Mean hourly carbohydrate intake was 38.9 g·hr-1. 11 days following the completion of the 26 marathons, body mass had reduced by 4.6 kg and lean body mass increasing by 0.53 kg when compared with 20 days prior. This case study highlights the importance of providing general and event-specific nutrition education when training for such an event. This is particularly prudent for multi-day endurance running events.

    Morphometric parameters, acquired notoriety mainly after the Drainage Density proposition (Horton 1932, 1945) and after they were applied by geomorphologists on the perspective to understand landscape functionalities, quantifying their characteristics through parameters and indexes. After the drainage density, many other parameters which describe the basin characteristics, behavior and dynamics have been proposed. Among them, for example, the DEI was proposed by Coelho Netto and contributors during the 80's, while they were seek to understand the hydrological and erosive dynamics on Bananal river basin (Brazilian Southeastern). Through this investigations the DEI was created, revealing the importance of parameters as hollow and drainage density, conjugated to the topographic gradient (Meis et al. 1982) who prosecute controls on the water flow efficiency along the hollows in order to activate the regressive erosion of the main channel. Later on this index was applied on the basin scale in several works developed in mountainous regions, showing a remarkable correlation with the occurrence of landslides such as showed by Coelho Netto et al. (2007); that posteriorly use this index as one of the components of the landslide susceptibility map for the Tijuca Massif, located in Rio de Janeiro Municipality. This work aims to establish patterns of the DEI index values (applied to mountainous low order basins) and the relationship on the occurrence of Debriflows or shallow translational slides. For this, the DEI index was applied on 4 different study areas located on the Southeastern mountainous region of Brazil to address deeply the connection between the index and the occurrence of landslides of different types applied for first and second order basins. The major study area is the Córrego Dantas Basin, situated in Nova Friburgo municipality (RJ), which is a 53 km² basin was affected by 327 landslides caused by a heavy rainfall on January 2011; Coelho Netto et al.

    Traditionally, flood risk assessment studies have been carried out from a univariate frequency analysis perspective. However, statistical dependence between hydrological variables, such as extreme rainfall and extreme sea surge, is plausible to exist, since both variables to some extent are driven by common meteorological conditions. Aiming to overcome this limitation, multivariate statistical techniques has the potential to combine different sources of flooding in the investigation. The aim of this study was to apply a range of statistical methodologies for analyzing combined extreme hydrological variables that can lead to coastal and urban flooding. The study area is the Elwood Catchment, which is a highly urbanized catchment located in the city of Port Phillip, Melbourne, Australia. The first part of the investigation dealt with the marginal extreme value distributions. Two approaches to extract extreme value series were applied (Annual Maximum and Partial Duration Series), and different probability distribution functions were fit to the observed sample. Results obtained by using the Generalized Pareto distribution demonstrate the ability of the Pareto family to model the extreme events. Advancing into multivariate extreme value analysis, first an investigation regarding the asymptotic properties of extremal dependence was carried out. As a weak positive asymptotic dependence between the bivariate extreme pairs was found, the Conditional method proposed by Heffernan and Tawn (2004) was chosen. This approach is suitable to model bivariate extreme values, which are relatively unlikely to occur together. The results show that the probability of an extreme sea surge occurring during a one-hour intensity extreme precipitation event (or vice versa) can be twice as great as what would occur when assuming independent events. Therefore, presuming independence between these two variables would result in severe underestimation of the flooding risk in the study area.

    Salinity is one of the major abiotic factors affecting the growth and productivity of crops in Hetao Irrigation District, China. In this study, the salinity tolerances of three local crops, wheat (Triticum aestinum L.), maize (Zea mays L.) and sunlfower (Helianthus annuus L.), growing in 76 farm ifelds are evaluated with modiifed discount function. Salinity ecological zones appropriate for these local crops are characterized and a case study is presented for crop salinity ecological zoning. The results show that the yield reductions of wheat, maize and sunlfower when grown in saline soils are attributed primarily to a reduction in spikelet number, 1000-grain weight and seed number per head, respectively. Sunlfower is the most tolerant crop among the three which had a salinity tolerance index (ST-index) of 12.24, folowed by spring maize and spring wheat with ST-Indices of 9.00 and 7.43, respectively. According to the crop salinity tolerance results, the arable land in the Heping Vilage of this district was subdivided into four salinity ecological zones: the most suitable, suitable, sub-suitable and unsuitable zones. The area proportion of the most suitable zone for wheat, maize and sunlfower within the Heping Vilage was 27.5, 46.5 and 77.5%, respectively. Most of the most suitable zone occurred in the western part of the vilage. The results of this study provide the scientiifc basis for optimizing the local major crop distribution and improving cultural practices management in Hetao Irrigation District.

    In this study, the application of a transductive support vector machine (TSVM), an innovative semi-supervised learning algorithm, has been proposed for mapping the potential drill targets at a detailed exploration stage. The semi-supervised learning method is a hybrid of supervised and unsupervised learning approach that simultaneously uses both training and non-training data to design a classifier. By using the TSVM algorithm, exploration layers at the Dalli porphyry Cu-Au deposit in the central Iran were integrated to locate the boundary of the Cu-Au mineralization for further drilling. By applying this algorithm on the non-training (unlabeled) and limited training (labeled) Dalli exploration data, the study area was classified in two domains of Cu-Au ore and waste. Then, the results were validated by the earlier block models created, using the available borehole and trench data. In addition to TSVM, the support vector machine (SVM) algorithm was also implemented on the study area for comparison. Thirty percent of the labeled exploration data was used to evaluate the performance of these two algorithms. The results revealed 87 percent correct recognition accuracy for the TSVM algorithm and 82 percent for the SVM algorithm. The deepest inclined borehole, recently drilled in the western part of the Dalli deposit, indicated that the boundary of Cu-Au mineralization, as identified by the TSVM algorithm, was only 15 m off from the actual boundary intersected by this borehole. According to the results of the TSVM algorithm, six new boreholes were suggested for further drilling at the Dalli deposit. This study showed that the TSVM algorithm could be a useful tool for enhancing the mineralization zones and consequently, ensuring a more accurate drill hole planning.

    A feasibility study on the seismic design of nuclear reactor buildings with application of a seismic isolation system is introduced. After the Hyogo-ken Nanbu earthquake in Japan of 1995, seismic isolation technologies have been widely employed for commercial buildings. Having become a mature technology, seismic isolation systems can be applied to NPP facilities in areas of high seismicity. Two reactor buildings are discussed, representing the PWR and BWR buildings in Japan, and the application of seismic isolation systems is discussed. The isolation system employing rubber bearings with a lead plug positioned (LRB) is examined. Through a series of seismic response analyses using the so-named standard design earthquake motions covering the design basis earthquake motions obtained for NPP sites in Japan, the responses of the seismic isolated reactor buildings are evaluated. It is revealed that for the building structures examined herein: (1) the responses of both isolated buildings and isolating LRBs fulfill the specified design criteria; (2) the responses obtained for the isolating LRBs first reach the ultimate condition when intensity of motion is 2.0 to 2.5 times as large as that of the design-basis; and (3) the responses of isolated reactor building fall below the range of the prescribed criteria.

    The goal of this paper is to analyse the impact of the implementation of a certification system on the management system (costs) of and the availability of land (quantity) for bioenergy production. Twelve socio-economic areas of concern (food supply, child labour, (minimum) wages, employment, health care and education) and environmental areas of concern (soil erosion, depletion of fresh water resources, nutrient losses and soil nutrient depletion, pollution from chemicals and biodiversity) are included. Since there is no generally accepted definition of sustainability, a loose and strict set of criteria are defined. Short rotation coppice (SRC) production systems in Ukraine and South East Brazil in 2015 are taken as case studies. The results indicate that it seems feasible to produce biomass for energy purposes at reasonable cost levels and meeting strict sustainability criteria at the same time. The loose set of criteria has no impact on the costs of energy crop production, which are calculated to be 1.7 EUR GJ{sup -1} in Brazil and 2.1 EUR GJ{sup -1} in Ukraine. The strict set of criteria results in an increase of the costs of energy crop production by 42 % in Brazil and 14 % in Ukraine. In general, compliance with strict socio-economic criteria has a limited impact on the costs, because SRC is relatively labour extensive. Strict environmental criteria likely have a larger impact.

    The innovative approach to the protection and management of water resources at the basin scale introduced by the European Union water framework directive (WFD) requires new scientific tools. WFD implementation also requires the participation of many stakeholders (administrators, farmers and citizens) with the aim of improving the quality of river waters and basin ecosystems through cooperative planning. This approach encompasses different issues, such as agro-ecology, land use planning and water management. This paper presents the results of a methodology suggested for implementing the WFD in the case of the Seveso river contract in Italy, one of the recent WFD applications. The Seveso basin in the Lombardy region has been one of the most rapidly urbanizing areas in Italy over the last 50 years. First, land use changes in the last 50 years are assessed with the use of historical aerial photos. Then, elements of an ecological network along the river corridor are outlined, and different scenarios for enhancing existing ecological connections are assessed using indicators from graph theory. These scenarios were discussed in technical workshops with involved stakeholders of the river contract. The results show a damaged rural landscape, where urbanization processes have decimated the system of linear green features (hedges/rows). Progressive reconnections of some of the identified network nodes may significantly increase the connectivity and circuitry of the study area.

    Full Text Available Problem statement: An integrated water resource management is accepted technique to solve the water resource problems both water shortage and flood plane in order to improve human life. The combination between local wisdom and modern technology by farmer participation is a main part of integrated management. The mentioned techniques had been being applied for human life in the northeast region of Thailand. Approach: This study investigated the local wisdom of water resource management and an application of the local wisdom to manage water resource for developing the economic, society and culture of Lam Ta Kong’s community, Nakhorn Ratchasima province, Thailand. Information was investigated from relevant document and field survey including questionnaire and interview. Results: The result founded that there were two types of the local wisdoms including an original local wisdom on water management and a combination of original and modern science local wisdom to manage available water. For original wisdom, there were earth dam, rock dam, rocks dyke, wooden weir, waterwheel and shallow well that were found in source and midst of the river basin. They constructed the dams and weirs barrier flow river along the Lam Ta Kong River in order to storage water for using purposes in dry season and to mitigate flood plane during rainy season as an early age of the local wisdom. The waterwheel was used to bail water from river to their community.

    Searches related to global warming have provided important insights into the response of terrestrial ecosystems, but few have examined the impacts on agricultural crops, particularly those associated with the monitoring of agrotoxin residues. In this context, the agriclimatological zoning is an important tool in the planning and consolidation of crops and should be considered in any initiative that involves such planning. This tool is particularly important in the analysis of agrotoxin residues and may be applied by the Program Analysis of Agrotoxin Residues in Food (PARA) created by the National Health Vigilance Agency of Brazil (ANVISA), which enables greater food security and contributes to the improvement of human health. The aim of this study was to elaborate the current and future agriclimatological zoning for the tomato crop, relating it with the monitoring of samples collected by PARA in Espírito Santo State, Brazil. The results indicate that a temperature increase of 5 °C creates a decrease in apt areas from 37.3% to 4.3%, for a total reduction of 33 percentage points (-88.5%). It is noted that of the 41 producing municipalities, only 26 have apt areas greater than 50%, highlighting the municipalities with apt areas greater than 90%, represented by Mantenópolis (100%), Guaçuí (98.5%), São José do Calçado (97.8%), Irupi (94.4%), Santa Teresa (92.3%), and Marechal Floriano (91.4%). The veracity of agriclimatological zoning is proved by a Kendall rank correlation coefficient of 0.876, indicating that the distribution of the variables of apt areas and productivity are similar at the significance level of 0.05 with a confidence interval 95%. After validation of the agriclimatological zoning for the tomato crop, it is recommended that the PARA should monitor 36 municipalities rather than the current 18, representing an increase of 100%. The methodology can be adjusted to agricultural crops of other countries.

    Resistivity and induced polarization (IP) measurements on soil contaminated with non-aqueous phase liquids (NAPLs) show a great variety in results in previous research. Several laboratory studies have suggested that the presence of NAPLs in soil samples generally decrease the magnitude of the IP-effect, while others have indicated the opposite. A number of conceptual models have been proposed suggesting that NAPLs can alter the pore space in different ways, e.g. by coating the grain surfaces and thus inhibiting grain polarization, or by changing the pore throat size and thus affecting the membrane polarization mechanism. The main aim of this paper is to review previously published conceptual models and to introduce some new concepts of possible residual NAPL configurations in the pore space. Time domain induced polarization measurements were performed at a NAPL contaminated field site, and the data were inverted using the Constant Phase Angle (CPA) model and the Cole-Cole model respectively. No significant phase anomalies were observed in the source area of the contamination when the CPA inverted profiles were compared with soil sampling results of free-phase contaminant concentrations. However, relatively strong phase and normalized phase anomalies appeared next to the source area, where residual free-phase presence could be expected according to the chemical data. We conclude that depending on the NAPL configuration, different spectral IP responses can be expected. In previous research, the NAPL configurations in different samples or field sites are often unknown, and this may to some extent explain why different results have been achieved by different authors. In our field case, we believe that the NAPL forms a more or less continuous phase in the pore space of the source zone leading to an absence of IP anomalies. The increase in phase and normalized phase angle observed next to the source zone is interpreted as a degradation zone. The ongoing biodegradation

    The NASA DEVELOP National Program conducts over eighty Earth science projects every year. Each project applies NASA Earth observations to impact decision-making related to a local or regional community concern. Small, interdisciplinary teams create a methodology to address the specific issue, and then pass on the results to partner organizations, as well as providing them with instruction to continue using remote sensing for future decisions. Many different methods are used by individual teams, and the program as a whole, to communicate results and research accomplishments to decision-makers, stakeholders, alumni, and the general public. These methods vary in scope from formal publications to more informal venues, such as social media. This presentation will highlight the communication techniques used by the DEVELOP program. Audiences, strategies, and outlets will be discussed, including a newsletter, microjournal, video contest, and several others.

    2012-01-01

    Medical eponyms are medical words derived from people's names. Eponyms, especially similar sounding eponyms, may be confusing to people trying to use them because the terms themselves do not contain physiologically descriptive words about the condition they refer to. Through the use of electronic health records (EHRs), embedded applied clinical informatics tools including synonyms and pick lists that include physiologically descriptive terms associated with any eponym appearing in the EHR can significantly enhance the correct use of medical eponyms. Here we describe a case example of two similar sounding medical eponyms--Wegener's disease and Wegner's disease-- which were confused in our EHR. We describe our solution to address this specific example and our suggestions and accomplishments developing more generalized approaches to dealing with medical eponyms in EHRs. Integrating brief physiologically descriptive terms with medical eponyms provides an applied clinical informatics opportunity to improve patient care.

    The Quick Urban & Industrial Complex (QUIC) atmospheric transport, and dispersion modelling, system was evaluated against the Joint Urban 2003 tracer-gas measurements. This was done using the wind and turbulence fields computed by the Weather Research and Forecasting (WRF) model. We compare the simulated and observed plume transport when using WRF-model-simulated wind fields, and local on-site wind measurements. Degradation of the WRF-model-based plume simulations was cased by errors in the simulated wind direction, and limitations in reproducing the small-scale wind-field variability. We explore two methods for importing turbulence from the WRF model simulations into the QUIC system. The first method uses parametrized turbulence profiles computed from WRF-model-computed boundary-layer similarity parameters; and the second method directly imports turbulent kinetic energy from the WRF model. Using the WRF model's Mellor-Yamada-Janjic boundary-layer scheme, the parametrized turbulence profiles and the direct import of turbulent kinetic energy were found to overpredict and underpredict the observed turbulence quantities, respectively. Near-source building effects were found to propagate several km downwind. These building effects and the temporal/spatial variations in the observed wind field were often found to have a stronger influence over the lateral and vertical plume spread than the intensity of turbulence. Correcting the WRF model wind directions using a single observational location improved the performance of the WRF-model-based simulations, but using the spatially-varying flow fields generated from multiple observation profiles generally provided the best performance.

    Modeling of volcanic morphometry provides reliable measurements of parameters that assist in the determination of volcanic landform degradation. Variations of the original morphology enable the understanding of patterns affecting erosion and their development, facilitating the assessment of associated hazards. A total of 24 volcanic Holocene eruptions were identified in the island of Gran Canaria (Canary Islands, Spain). 87% of these eruptions occurred in a wet environment while the rest happened in a dry environment. 45% of Holocene eruptions are located along short barrancos (S-type, less than 10 km in length), 20% along large barrancos (L-type, 10-17 km in length) and 35% along extra-large barrancos (XL-type, more than 17 km in length). The erosional history of Holocene volcanic edifices is in the first stage of degradation, with a geomorphic signature characterized by a fresh, young cone with a sharp profile and a pristine lava flow. After intensive field work, a careful palaeo-geomorphological reconstruction of the 24 Holocene eruptions of Gran Canaria was conducted in order to obtain the Digital Terrain Models (DTMs) of the pre- and post-eruption terrains. From the difference between these DTMs, the degradation volume and the incision rate were obtained. The denudation of volcanic cones and lava flows is relatively independent both their geographical location and the climatic environment. However, local factors, such as pre-eruption topography and ravine type, have the greatest influence on the erosion of Holocene volcanic materials in Gran Canaria. Although age is a key factor to help understand the morphological evolution of monogenetic volcanic fields, the Gran Canaria Holocene volcanism presented in this paper demonstrates that local and regional factors may determine the lack of correlation between morphometric parameters and age. Consequently, the degree of transformation of the volcanic edifices evolves, in many cases, independently of their age.

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    Full Text Available Abstract Background While translation of evidence into health policy and practice is recognised as critical to optimising health system performance and health-related outcomes for consumers, mechanisms to effectively achieve these goals are neither well understood, nor widely communicated. Health Networks represent a framework which offers a possible solution to this dilemma, particularly in light of emerging evidence regarding the importance of establishing relationships between stakeholders and identifying clinical leaders to drive evidence integration and translation into policy. This is particularly important for service delivery related to chronic diseases. In Western Australia (WA, disease and population-specific Health Networks are comprised of cross-discipline stakeholders who work collaboratively to develop evidence-informed policies and drive their implementation. Since establishment of the Health Networks in WA, over 50 evidence-informed Models of Care (MoCs have been produced across 18 condition or population-focused Networks. The aim of this paper is to provide an overview of the Health Network framework in facilitating the translation of evidence into policy and practice with a particular focus on musculoskeletal health. Case presentation A review of activities of the WA Musculoskeletal Health Network was undertaken, focussing on outcomes and the processes used to achieve them in the context of: development of policy, procurement of funding, stakeholder engagement, publications, and projects undertaken by the Network which aligned to implementation of MoCs. The Musculoskeletal Health Network has developed four MoCs which reflect Australian National Health Priority Areas. Establishment of community-based services for consumers with musculoskeletal health conditions is a key recommendation from these MoCs. Through mapping barriers and enablers to policy implementation, working groups, led by local clinical leaders and supported by

    Full Text Available The calibration of hydrologic models is a worldwide challenge due to the uncertainty involved in the large number of parameters. The difficulty even increases in a region with high seasonal variation of precipitation, where the results exhibit high heteroscedasticity and autocorrelation. In this study, the Generalized Likelihood Uncertainty Estimation (GLUE method was combined with the Soil and Water Assessment Tool (SWAT to quantify the parameter uncertainty of the stream flow and sediment simulation in the Daning River Watershed of the Three Gorges Reservoir Region (TGRA, China. Based on this study, only a few parameters affected the final simulation output significantly. The results showed that sediment simulation presented greater uncertainty than stream flow, and uncertainty was even greater in high precipitation conditions (from May to September than during the dry season. The main uncertainty sources of stream flow came from the catchment process while a channel process impacts the sediment simulation greatly. It should be noted that identifiable parameters such as CANMX, ALPHA_BNK, SOL_K could be obtained with an optimal parameter range using calibration method. However, equifinality was also observed in hydrologic modeling in TGRA. This study demonstrated that care must be taken when calibrating the SWAT model with non-identifiable parameters because these may lead to equifinality of the parameter values. It was anticipated this study would provide useful information for hydrology modeling related to policy development in the Three Gorges Reservoir Region (TGRA and other similar areas.

    Noise mapping has been used as an instrument for assessment of environmental noise, helping to support decision making on urban planning. In Brazil, urban noise is not yet recognized as a major environmental problem by the government. Besides, cities that have databases to drive acoustic simulations, making use of advanced noise mapping systems, are rare. This study sought an alternative method of noise mapping through the use of geoprocessing, which is feasible for the Brazilian reality and for other developing countries. The area chosen for the study was the central zone of the city of Sorocaba, located in São Paulo State, Brazil. The proposed method was effective in the spatial evaluation of equivalent sound pressure level. The results showed an urban area with high noise levels that exceed the legal standard, posing a threat to the welfare of the population.

    Formerly covered by a tropical forest, the study area was deforested in the early 40's for coffee plantation and cattle raising, which caused intense gully erosion problems. To develop a method to analyze the relationship between land use and soil erosion, visual interpretations of aerial photographs (scale 1:25.000), MSS-LANDSAT imagery (scale 1:250,000), as well as automatic interpretation of computer compatible tapes by IMAGE-100 system were carried out. From visual interpretation the following data were obtained: land use and cover tapes, slope classes, ravine frequency, and a texture sketch map. During field work, soil samples were collected for texture and X-ray analysis. The texture sketch map indicate that the areas with higher slope angles have a higher susceptibilty to the development of gullies. Also, the over carriage of pastureland, together with very friable lithologies (mainly sandstone) occuring in that area, seem to be the main factors influencing the catastrophic extension of ravines in the study site.

    Satellite remote sensing data are usually used to analyze the spatial distribution pattern of geological structures and generally serve as a significant means for the identification of alteration zones. Based on the Landsat Enhanced Thematic Mapper (ETM+) data, which have better spectral resolution (8 bands) and spatial resolution (15 m in PAN band), the synthesis processing techniques were presented to fulfill alteration information extraction: data preparation, vegetation indices and band ratios, and expert classifier-based classification. These techniques have been implemented in the MapGIS-RSP software (version 1.0), developed by the Wuhan Zondy Cyber Technology Co., Ltd,China. In the study area application of extracting alteration information in the Zhaoyuan (招远) gold mines, Shandong (山东) Province, China, several hydorthermally altered zones (included two new sites) were found after satellite imagery interpretation coupled with field surveys. It is concluded that these synthesis processing techniques are useful approaches and are applicable to a wide range of gold-mineralized alteration information extraction.

    2011-08-01

    Full Text Available Irrigation use constitutes an alternative to improve maize production in Central Minas Gerais State, Brazil. However, even under adequate water supply conditions, other environmental factors may influence maize crop growth and development and may, ultimately, affect grain yield. This study aimed to establish a sowing window for irrigated maize crop, based on simulation results obtained with the decision support model CSM-CERES-Maize. Simulations were made for crop management conditions of Riacho´s Farm, located in Matozinhos, Minas Gerais State, Brazil. It was employed the model´s seasonal tool, along with a data set containing 46 years of weather data records, to simulate maize yield for weekly sowing scenarios, starting on August 1st and ending on July 24th of each year. One defined an irrigated maize sowing window, taking into account the yield break risk that a farmer would be willing to take. The model proved to be an interesting tool to assist in decision making, regarding crop and irrigation management, for an irrigated maize production system. Assuming a 10% yield break in the expected average maximum maize yield, it was defined as sowing window, the period from January 23rd to March 6th, with February 20th as the best sowing date. Other sowing windows may be established according to the risk that the farmer would be willing to take.

    Knowledge on ecosystem functioning can largely contribute to promote ecosystem-based management and its application. The Mar Piccolo of Taranto is a densely populated area at a high risk of environmental crisis. Here, planktonic primary production (PP) and heterotrophic prokaryotic production (HPP) were measured as proxies of functioning in three sampling sites located in two inlets at different levels of industrial contamination, during three sampling surveys (June 2013, February and April 2014). To have a better overall view and provide some insights into the benthic-pelagic coupling, we integrated PP and HPP in the water column with those in the sediments and then discussed this with the origin of the organic matter pools based on analysis of stable isotopes. Heavy metals and polychlorobiphenyls (PCBs) were also analysed in the surface (1 cm) sediment layer and related to the overall ecosystem functioning. Multidimensional scaling (MDS) analysis, based on the main data, clearly separated the second inlet from the first one, more severely impacted by anthropogenic activities. The stable isotope mixing model suggested the prevalent terrestrial/riverine origin of the particulate organic matter pools (mean 45.5 %) in all sampling periods, whereas phytoplankton contributed up to 29 % in February. Planktonic PP and HPP rates followed the same pattern over the entire study period and seemed to respond to phytoplankton dynamics confirming this community as the main driver for the C cycling in the water column. On the contrary, benthic PP rates were almost negligible while HPP rates were lower or comparable to those in the water column indicating that although the Mar Piccolo is very shallow, the water column is much more productive than the surface sediments. The sediment resuspension is likely responsible for a pulsed input of contaminants into the water column. However, their interference with the proper functioning of the pelagic ecosystem seems to be limited to

    Full Text Available Abstract Background Revised consensus sepsis definitions have been published in 2003. The present study was performed to compare the prevalence of different stages of sepsis and ICU mortality rates and find out the case mix within the same collective of postoperative/posttraumatic patients applying either the original 1992 ACCP/SCCM or the revised 2003 SCCM/ESICM/ACCP/ATS/SIS sepsis definitions. Methods Retrospective observational single-centre study in surgical critically ill patients admitted to an University adult ICU. From 01/2007 to 12/2007, 742 patients were surveyed daily computer-assisted with respect to different stages of sepsis. Results Within the same patient collective, applying the 2003 definitions instead of the 1992 definitions, prevalence of severe sepsis (61 vs. 56 and septic shock (205 vs. 162 was higher (p Conclusion The prevalence and mortality rates of various sepsis severity stages differ if defined by the 1992 or the 2003 definitions. Thus, transferring conclusions drawn from data sets regarding severity of sepsis generated with the 1992 definitions to the same population applying the 2003 definitions may be misleading. The 1992 definitions may under-classify patients with severe sepsis.

  13. APPLYING THE KUZNETS CURVE IN CASE OF ROMANIA

    Full Text Available The Romanian economy experienced a contrasting trend in recent years. Some of its features are similar to those of other Central and Eastern European Countries, that have joined the European Union in May 2004 and 2007, but some of them are very specific. Indicators of convergence and catching-up seem to show a GAP between Romania and other European countries, and even other CEEC. Indicators of convergence and catch-up are usually used to analyse the effectiveness of EU policies applied in all European countries. Apparent Romanian lag may be the result of too important weight of the rural sector in the economy. This sector is characterised, for example, by too many farms and very small agricultural holdings that induces a certain loss in productivity, also by low income and poverty. This result is consequence of both the story and original policy choices. This paper consists of two parts. In the first one, we detail the specificities of new member states and particularly Romanian. The second part allows analysing the link between the agricultural sector and development. Notably, the Kuznets curve can be used as a tool in order to better understand the mechanism of this link. The Kuznets hypothesis is applied to the case of Romania and allows us to draw some conclusions about the recent developments.

    Full Text Available This study has three objectives. First, we investigate whether Modern Portfolio Theory can be applied on the financial decisions that made by investors or individual in order to increase their wealth through investment activities. Second, we examine the real behavior of each asset in terms of capital assets pricing models. Third, we determine whether our portfolio is the best model to produce a higher return in a given level of risk or a lowest risk in a particular level of return. It is found that three different stocks listed in the Indonesia Stock Exchange have a positive relationship with market returns. The reactions of the investor regarding these stocks are not influenced by each other. Lastly, the minimum variance portfolio (MVP point which represents the single portfolio with the lowest possible level of standard deviation, occurs when the expected return of portfolio is approximately 2.2 percent at a standard deviation of 8.8 percent.

    Full Text Available This study explores the rhetorical structure of introductions that are followed by an independent Literature Review (L section. It is motivated by an increasing use or even the prevalent use of both the introduction and L sections in the opening phase of empirical research articles in many disciplines and the lack of systematic genre-based investigation of introductions with a following L section. Based on a detailed examination of 30 introductions with a subsequent L section in Applied Linguistics, this study found that they generally can be classified into two categories according to their communicative functions and structures. They are the traditional CARS type that largely follows the classic “Create a Research Space” (CARS model and the innovative Two-move Orientation type. Some featured elements used in the introductions with a subsequent L are identified and the “Two-move Orientation” approach is formulated for the rhetorical structure of this new type of introductions. The interesting links between introduction and L are also suggested. The study contributes to our understanding of the structure and function of this important part-genre in a new generic context (that is, introductions being followed by an independent L section and illuminates the current genre-based teaching of introduction writing.

    Tectonic earthquakes of high magnitude can cause considerable losses in terms of human lives, economic and infrastructure, among others. According to an evaluation published by the U.S. Geological Survey, 30 is the number of earthquakes which have greatly impacted Mexico from the end of the XIX century to this one. Based upon data from the National Seismological Service, on the period between January 1, 2006 and May 1, 2013 there have occurred 5,826 earthquakes which magnitude has been greater than 4.0 degrees on the Richter magnitude scale (25.54% of the total of earthquakes registered on the national territory), being the Pacific Plate and the Cocos Plate the most important ones. This document describes the development of an Artificial Neural Network (ANN) based on the radial topology which seeks to generate a prediction with an error margin lower than 20% which can inform about the probability of a future earthquake one of the main questions is: can artificial neural networks be applied in seismic forecast...

  3. Neuropeptidomics applied to studies of mammalian reproduction

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Neuropeptidomics, a mass spectrometry-based technique which aims to uncover the complete suite of neuropeptides present in a tissue, organ or cell from the brain or nervous system, has found application in studies examining physiological responses (e.g. food intake, appetite and reproduction. Neuropeptides (and peptide hormones have long been known as regulators of mammalian physiological processes, particularly reproduction. These peptides are derived from precursor proteins and become active via proteolytic processes and post-translational modifications. A relatively large number of neuropeptides, mainly formed in the hypothalamus or the anterior pituitary of mammals, have been specifically associated with reproduction, including GnRH, NPY, PYY and kisspeptin. Here, we will present an overview of neuropeptides, their roles in reproduction and the application of neuropeptidomics in this field. We address the advantages of neuropeptidomics in reproductive studies including the high throughput identification, profiling and quantification of neuropeptides present in reproductive tissues and also discuss some of the challenges. The application of neuropeptidomics to the field of reproduction will provide the foundation for a greater understanding of how neuropeptides act to regulate reproductive function.

  4. Fundamental and Applied Studies of Polymer Membranes

    Science.gov (United States)

    Imbrogno, Joseph

    Four major areas have been studied in this research: 1) synthesizing novel monomers, e.g. chiral monomers, to produce new types of functionalized membranes for the biotechnology and pharmaceutical industries, 2) hydrophobic brush membranes for desalinating brackish water, sea water, and separating organics, 3) fundamental studies of water interactions at surfaces using sum frequency generation (SFG), and 4) discovering new surface chemistries that will control the growth and differentiation of stem cells. We have developed a novel synthesis method in order to increase the breadth of our high throughput screening library. This library was generated using maleimide chemistry to react a common methacrylate linker with a variety of different functions groups (R groups) in order to form new monomers that were grafted from the surface of PES ultrafiltration membranes. From this work, we discovered that the chirality of a membrane can affect performance when separating chiral feed streams. This effect was observed when filtering bovine serum albumin (BSA) and ovalbumin in a high salt phosphate buffered saline (PBS, 150 mM salt). The Phe grafted membranes showed a large difference in performance when filtering BSA with selectivity of 1.13 and 1.00 for (S) and (R) Phe, respectively. However, when filtering ovalbumin, the (S) and (R) modified surfaces showed selectivity of 2.06 and 2.31, respectively. The higher selectivity enantiomer switched for the two different proteins. Permeability when filtering BSA was 3.06 LMH kPa-1 and 4.31 LMH kPa -1 for (S)- and (R)- Phe, respectively, and 2.65 LMH kPa -1 and 2.10 LMH kPa-1 when filtering ovalbumin for (S)- and (R)- Phe, respectively. Additionally, these effects were no longer present when using a low salt phosphate buffer (PB, 10 mM salt). Since, to our knowledge, membrane chirality is not considered in current industrial systems, this discovery could have a large impact on the pharmaceutical and biotechnology industries. We

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

    Case study as a research design means investigating a single or multiple instance(s) or setting(s) (i.e. a case) and its entire context to explain a phenomenon and its processes. This is achieved through detailed understanding, usually comprised of multiple sources of information. In this way, case...... studies attempt to provide as a complete an understanding of a (complex) phenomenon as possible. Within the AEGIS project, survey and case study research are complementary. They are complementary in the sense that the former can provide more generalizable evidence on a phenomenon in terms of cross......-sectional data, while the latter can provide more in-depth (qualitative) understanding on specific issues.

  11. Dioxin: a case study.

    Science.gov (United States)

    Bond, G G

    1993-01-01

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

  12. Case studies--ergonomics in projects.

    The aim of a series of sessions on Company Case Studies, is to learn from practical experiences, to give feed back to researchers on applicability of theories, methods and techniques, and last but not least, to market ergonomics. In order to learn from case material, reports need to be easy accessible and well structured. System ergonomics provides such a structure. Usually a project is not done twice, i.e. with and without ergonomics. Therefore, it is not possible to make comparisons and determine the impact of ergonomics directly. A different approach is needed. It has been suggested at the IEA2006 World Congress, to compile a database of published case studies, each case to be reported in a fixed report format and critically reviewed to enable generalizing the outcomes. This paper proposes such a format. At the IEA2012 World Congress 40 case studies have been accepted, representing applied ergonomics cases in manufacturing, process industries, aviation and logistic systems.

    The goal of this study is to make a first attempt to analyse the impact on the potential (quantity) and the costs (per unit) of bioenergy that the compliance with various sustainability criteria brings along. The nature of this work is exploratory. Because of the broad set of issues covered very little work has been published on which we could build. Ukraine and Brazil are used as case studies, because both regions are identified as promising bioenergy producers. This study is part of the FAIR Biotrade project, which is aimed to identify and quantify the impact of sustainability criteria on the potential of bioenergy. Previous work includes an identification of sustainability criteria relevant for bioenergy, an assessment of the environmental and economic costs of long distance biotrade and an assessment of bioenergy production potentials in 2050 in various world regions. In section 2 the approach is presented which is used to select and quantify the impact of sustainability criteria on bioenergy production. In section 3 the selection of the various sustainability criteria is described in detail, followed by a detailed description of how the various socials, ecological and economical sustainability criteria are operationalised. In section 4 (intermediate) results are presented for each sustainability criterium. In section 5 final results are presented, followed by a discussion and by conclusions (section 6)

    2012-03-01

    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

    2011-06-01

    A 24 year university student with history of productive cough was registered as sputum smear confirmed case of pulmonary tuberculosis. During treatment, patient suffered from itchiness associated with anti tuberculosis drugs and was treated with chlorpheniramine (4mg) tablet. Patient missed twenty eight doses of anti tuberculosis drugs in continuation phase claiming that he was very busy in his studies and assignments. Upon questioning he further explained that he was quite healthy after five months and unable to concentrate on his studies after taking prescribed medicines. His treatment was stopped based on clinical improvement, although he did not complete six months therapy. Two major reasons; false perception of being completely cured and side effects associated with anti TB drugs might be responsible for non adherence. Non sedative anti histamines like fexofenadine, citrizine or loratidine should be preferred over first generation anti histamines (chlorpheniramine) in patients with such lifestyle. Patient had not completed full course of chemotherapy, which is preliminary requirement for a case to be classified as "cure" and "treatment completed". Moreover, patient had not defaulted for two consecutive months. Therefore, according to WHO treatment outcome categories, this patient can neither be classified as "cure" or "treatment completed" nor as "defaulter". Further elaboration of WHO treatment outcome categories is required for adequate classification of patients with similar characteristics.

    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

  13. A diagnostic procedure for applying the social-ecological systems framework in diverse cases

    Directory of Open Access Journals (Sweden)

    Jochen Hinkel

    2015-03-01

    Full Text Available The framework for analyzing sustainability of social-ecological systems (SES framework of Elinor Ostrom is a multitier collection of concepts and variables that have proven to be relevant for understanding outcomes in diverse SES. The first tier of this framework includes the concepts resource system (RS and resource units (RU, which are then further characterized through lower tier variables such as clarity of system boundaries and mobility. The long-term goal of framework development is to derive conclusions about which combinations of variables explain outcomes across diverse types of SES. This will only be possible if the concepts and variables of the framework can be made operational unambiguously for the different types of SES, which, however, remains a challenge. Reasons for this are that case studies examine other types of RS than those for which the framework has been developed or consider RS for which different actors obtain different kinds of RU. We explore these difficulties and relate them to antecedent work on common-pool resources and public goods. We propose a diagnostic procedure which resolves some of these difficulties by establishing a sequence of questions that facilitate the step-wise and unambiguous application of the SES framework to a given case. The questions relate to the actors benefiting from the SES, the collective goods involved in the generation of those benefits, and the action situations in which the collective goods are provided and appropriated. We illustrate the diagnostic procedure for four case studies in the context of irrigated agriculture in New Mexico, common property meadows in the Swiss Alps, recreational fishery in Germany, and energy regions in Austria. We conclude that the current SES framework has limitations when applied to complex, multiuse SES, because it does not sufficiently capture the actor interdependencies introduced through RS and RU characteristics and dynamics.

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

    The focus of this study was addressed to investigate the potentiality of HyperSpectral Imaging (HSI) in the monitoring of commercial consolidant products applied on wood samples. Poplar (Populus Sp.) and walnut (Juglans Regia L.) were chosen for the consolidant application. Both traditional and innovative products were selected, based on acrylic, epoxy and aliphatic compounds. Wood samples were stresses by freeze/thaw cycles in order to cause material degradation. Then the consolidants were applied under vacuum. The samples were finally artificially aged for 168 hours in a solar box chamber. The samples were acquired in the SWIR (1000-2500 nm) range by SISUChema XL™ device (Specim, Finland) after 168 hours of irradiation. As comparison, color measurement was also used as economic, simple and noninvasive technique to evaluate the deterioration and consolidation effects on wood. All data were then processed adopting a chemometric approach finalized to define correlation models, HSI based, between consolidating materials, wood species and short time ageing effects.

    Acar, Maria Elizabeth Dias

    2015-07-01

    A methodology combining process mapping and analysis; knowledge elicitation mapping and critical analysis; and socio technical analysis based on social network analysis was conceived. The methodology was applied to a small knowledge intensive organization - LNMRI, and has allowed the appraisal of the main intellectual assets and their ability to evolve. In this sense, based on real issues such as attrition, the impacts of probable future scenarios were assessed. For such task, a multimodal network of processes, knowledge objects and people was analyzed using a set of appropriate metrics and means, including sphere of influence of key nodes. To differentiate the ability of people's role playing in the processes, some nodes' attributes were used to provide partition criteria for the network and thus the ability to differentiate the impact of potential loss of supervisors and operators. The proposed methodology has allowed for: 1) the identification of knowledge objects and their sources; 2) mapping and ranking of these objects according to their relevance and 3) the assessment of vulnerabilities in LNMRI's network structure and 4) revealing of informal mechanisms of knowledge sharing The conceived methodological framework has proved to be a robust tool for a broad diagnosis to support succession planning and also the organizational strategic planning.

    Science.gov (United States)

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

    concentrated solutions over the entire pH range. Complete and improved chemical, thermodynamic and activity (SIT, Pitzer) models were derived. The second part of this work focuses on applied Tc chemistry in near-natural systems. Interaction of Tc(VII) with crystalline rock material from a prospective repository site (Nizhnekansky massif, Russia) and from an underground research laboratory (AespoeHRL, Sweden) were studied. Drilling of the Aespoecores were performed under anoxic conditions. Part of the material was artificially oxidized to test the importance of sample preservation. Batch sorption studies under variation of the Tc(VII) concentration were performed in synthetic groundwater simulate to estimate the retention kinetics and R{sub s} values. For better understanding of the retention mechanisms, advanced surface sensitive analytics (XPS, XANES) were carried out and the data compared to reference systems. Tc migration behavior was further investigated by injections of Tc(VII)-containing groundwater simulant into the natural fracture in the unoxidized Aespoediorite core. The data obtained are compared with the results of batch sorption studies and will be used for subsequent geochemical reactive transport modeling. This work highlights the importance of combining fundamental Tc chemistry and applied studies in order to derive a comprehensive assessment of Tc mobilization and retention processes in support of the nuclear waste disposal Safety Case.

    Against the backdrop of global oil industry trends and the specificity of the Brazilian energy sector, this study evaluates whether the option to develop a national market linked with a plan to export liquefied natural gas produced in Brazil is financially advantageous relative to the traditional pipeline alternative for the aim of satisfying the current natural gas deficit in the Northeast region. To this end, this dissertation analyses the economic conditions for Brazilian LNG in the international gas market, mainly for European and North-American gas markets. Employing a probabilistic analysis based on the Monte Carlo method and given the premises adopted and the amount of information available at the time of writing, the study concludes that, while the international LNG market has enjoyed vigorous growth in recent years, the option of using it as a strategy to develop local market is a less attractive investment choice compared with the pipeline alternative.

    1999-02-01

    This paper attempts a partial, critical look at the construction and use of case studies in ethics education. It argues that the authors and users of case studies are often insufficiently aware of the literary nature of these artefacts: this may lead to some confusion between fiction and reality. Issues of the nature of the genre, the fictional, story-constructing aspect of case studies, the nature of authorship, and the purposes and uses of case studies as "texts" are outlined and discussed. The paper concludes with some critical questions that can be applied to the construction and use of case studies in the light of the foregoing analysis.

    2015-01-01

    Full Text Available There are lots of factors which can directly affect output efficiency of photovoltaic device. One of them is high temperature which would cause adverse effect to solar cell. When solar cell is operated in high temperature, the cell’s output efficiency will become low. Therefore, improving thermal spreading of solar cell is an important issue. In this study, we focused on finding new materials to enhance the thermal dispreading and keep the temperature of solar cell as low as possible. The new materials are different from conventional metal ones; they are called “phase change materials (PCMs” which are mainly applied to green buildings. We chose two kinds of PSMs to study their thermal dispreading ability and to compare them with traditional aluminum material. These two kinds of PCMs are wax and lauric acid. We made three aluminum-based cuboids as heat sinking units and two of them were designed with hollow space to fill in the PCMs. We applied electric forward bias on solar cells to simulate the heat contributed from the concentrated sunlight. Then we observed the thermal distribution of these three kinds of thermal spreading materials. Two levels of forward biases were chosen to test the samples and analyze the experiment results.

    Full Text Available Objective: In the present study, to assess the sexual assault victims considering sociodemographic and forensic psychiatry who were examined by our Board of Physical and Mental Health was aimed. Methods: The cases who were examined in Board of Physical and Mental Health in Forensic medicine Department of Dicle University, Faculty of Medicine were assessed retrospectively in terms of age, gender, marital status, education level, relation of the victim with the accused, presence of penetration and disruption of physical and mental health. Results: Among 258 cases, who referred to our board, 196 were female and 62 were male. The age range of the victims was 2 to 50 and average age was detected as 13.1 ± 5.9 years. It was determined that 227 (88% cases were under 18 years and 31 cases (12% were above 18 years. Vaginal and anal penetration was claimed in 48 and 61 cases, respectively; oral + anal penetration was claimed in 11 cases; both vaginal and oral penetration was claimed in two cases. Among 258 cases, 144 cases had no physical and mental disruption; 49 cases were diagnosed with mental and physical health disruption and 65 cases were followed by issuing a preliminary report. Conclusion: As a result of our study any significant relation is not found between impairment in psychological health and sex, marital status, educational level of the victim, age groups, the age difference between the victim and the defendant. Therefore, it is understood that either men or women, married or single, educated or uneducated people are affected emotionally as bad as from sexual assault. This supports the idea that, especially in cases that any findings cannot be obtained with genital and physical examination, psychological evaluation may be important.

    Full Text Available This paper addresses the adaptation of the method of classification of unpaved roads developed by Eaton to the field conditions of local roads from the city of Viçosa, Minas Gerais State, Brazil, considering its potential as a support tool for the management of these roads. This study was developed encompassing objective evaluation, carried out with the application of a note scale, and subjective evaluation, according to the methodology of Eaton, which were performed by a team that accomplished the field inspections, attributing notes to the 20 sample units, each one 50 meters long and representing 10 analyzed unpaved road segments. Conclusions are as follows: (i it was not observed any correlation between data from the objective and the subjective field evaluations, leading to the conclusion that the use of the Eaton and others methodologies can be misleading to the management of the maintenance of unpaved not reflecting their real priorities; (ii there is correlation between the subjective evaluation of the road sections and the subjective evaluation of all sample units, indicating to be consistent the application of this procedure.

    Sodium fluoride solution was injected i.p. to rats at a dose equivalent to 0.1 LD50 three times a week up to 18 injections. Two thirds of these rats and of the sham-injected ones were exposed to the whole body impact of a 25 mT static magnetic field for 2 or 4 h a day, 5 times a week. For mathematical analysis of the effects they produced in combination, we used a response surface model. This analysis demonstrated that (like in combined toxicity) the combined adverse action of a chemical plus a physical agent was characterized by a diversity of types depending not only on particular effects these types were assessed for but on their level as well. From this point of view, the indices for which at least one statistically significant effect was observed could be classified as identifying (1) single-factor action; (2) additivity; (3) synergism; (4) antagonism (both subadditive unidirectional action and all variants of contradirectional action). Although the classes (2) and (3) taken together encompass a smaller part of the indices, the biological importance of some of them renders the combination of agents studied as posing a higher health risk than that associated with each them acting alone.

    Ergotamine is a well known pharmacological remedy applied in neurology (treatment of vascular headache) and in obstetrics (abortive remedy, uterus atony). But today it is rarely used, because of new safer anti-migraine medicine (triptanes) which cause fewer side effects. According to obstetrical indications ergotamine is applied only in hospital treatment. For that reason, cases of intoxication by this class of drugs are rarely observed. Ergotamine causes constriction of the blood vessels through the blockade of alpha-receptors and stimulation of the serotonin-receptors on the walls of blood vessels both in the central nervous system and in peripheral circulation. Intoxication/overdose symptoms may appear on application of therapeutic dose by sensitive patients, mostly by patients with migraine headache using ergotamine preparation for relief of migraine attacks. In the Regional Centre of Clinical Toxicology, a 21-year-old patient was hospitalized. She took about 20 tablets of Cafergot (complex preparation containing 1mg ergotamine tartare and 100mg caffeine). During her stay on the ward, typical symptoms of severe poisoning were observed: nausea, severe vomiting, dizziness, decreased blood pressure without perceptible pulse, narrowing of the blood vessels in the extremities of the body (peripheral vasoconstriction) - paresthesia, digital cyanosis, refrigeration of legs, angina. Due to taking once of a great dose of the drug by the patient, violent process of intoxication, possibility of dangerous complication and also the unavailability of specific antidotes and lack of efficient methods of extracorporeal elimination of the drug, the patient was intensively controlled and symptomatic treatments according to the law of intensive therapy was applied.

  3. The estimated magnitude of AIDS in Brazil: a delay correction applied to cases with lost dates

    Directory of Open Access Journals (Sweden)

    Barbosa Maria Tereza S.

    2002-01-01

    Full Text Available The number of HIV-infected people is an important measure of the magnitude of the AIDS epidemic in Brazil and allows for comparison with epidemic patterns in other countries. This quantity can be estimated from the number of reported AIDS cases, which in turn needs to be corrected for the distribution of reporting delays and under-recording of cases. These distributions are unknown and must also be estimated from the recorded dates, which were missed to the Brazilian National AIDS registry. This paper estimates the number of AIDS cases diagnosed by imputing the lost information based on an estimate of the pattern in registration delay until 1996. We first fitted a non-stationary bivariate Poisson regression model to estimate the pattern in reporting delay. In the subsequent steps these models were applied to impute new data, thus replacing the missing information, and to estimate the magnitude of the AIDS epidemic in the country. Model estimates ranged from 36,000 to 50,000 AIDS cases diagnosed in Brazil and still unreported. Therefore, the epidemic was 20 to 30% greater than known from the available information as of February 1999. To be useful to health policy-makers, the surveillance system based on officially reported AIDS cases must be continuously improved.

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    Weisfeld, Glenn E; Goetz, Stefan M M

    2013-09-01

    This paper argues for invoking evolutionary, functional thinking in analyzing emotions. It suggests that the fitness needs of normal individuals be kept in mind when trying to understand emotional behavior. This point of view is elaborated in sections addressing these topics: defining emotion; applying comparative analysis to the study of emotions; focusing on the elicitors and resulting motivated behaviors mediated by the various affects; recognizing that not all emotions have prominent, distinct facial expressions; acknowledging all of the basic emotions and not just some exemplars; crediting the more sensible Cannon-Bard theory over James-Lange; recognizing the more ancient, fundamental role of the limbic system in emotion compared with that of the neocortex; and analyzing socio-emotional interactions as they occur naturally, not just individual emotional behavior studied under artificial conditions. Describing the various facets and neuroendocrine mechanisms of each basic emotion can provide a framework for understanding the normal and pathological development of each emotion. Such an inventory, or ethogram, would provide a comprehensive list of all of the observable behavioral tendencies of our species.

  13. Applying functional genomics research to the study of pig reproduction.

    Pomp, D; Caetano, A R; Bertani, G R; Gladney, C D; Johnson, R K

    2001-01-01

    Functional genomics is an experimental approach that incorporates genome-wide or system-wide experimentation, expanding the scope of biological investigation from studying single genes to studying potentially all genes at once in a systematic manner. This technology is highly appealing because of its high throughput and relatively low cost. Furthermore, analysis of gene expression using microarrays is likely to be more biologically relevant than the conventional paradigm of reductionism, because it has the potential to uncover new biological connections between genes and biochemical pathways. However, functional genomics is still in its infancy, especially with regard to the study of pig reproduction. Currently, efforts are centred on developing the necessary resources to enable high throughput evaluation and comparison of gene expression. However, it is clear that in the near future functional genomics will be applied on a large scale to study the biology and physiology of reproduction in pigs, and to understand better the complex nature of genetic control over polygenic characteristics, such as ovulation rate and litter size. We can look forward to generating a significant amount of new data on differences in gene expression between genotypes, treatments, or at various temporal and spatial coordinates within a variety of reproductively relevant systems. Along with this capability will be the challenge of collating, analysing and interpreting datasets that are orders of magnitude more extensive and complex than those currently used. Furthermore, integration of functional genomics with traditional genetic approaches and with detailed analysis of the proteome and relevant whole animal phenotypes will be required to make full use of this powerful new experimental paradigm as a beneficial research tool.

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

    2015-07-01

    The scientific study of artistic and cultural heritage objects have been routinely performed in Europe and the United States for decades. In Brazil this research area is growing, mainly through the use of physical and chemical characterization methods. Since 2003 the Group of Applied Physics with Particle Accelerators of the Physics Institute of the University of Sao Paulo (GFAA-IF) has been working with various methodologies for material characterization and analysis of cultural objects. Initially using ion beam analysis performed with Particle Induced X-Ray Emission (PIXE), Rutherford Backscattering (RBS) and recently Ion Beam Induced Luminescence (IBIL), for the determination of the elements and chemical compounds in the surface layers. These techniques are widely used in the Laboratory of Materials Analysis with Ion Beams (LAMFI-USP). Recently, the GFAA expanded the studies to other possibilities of analysis enabled by imaging techniques that coupled with elemental and compositional characterization provide a better understanding on the materials and techniques used in the creative process in the manufacture of objects. The imaging analysis, mainly used to examine and document artistic and cultural heritage objects, are performed through images with visible light, infrared reflectography (IR), fluorescence with ultraviolet radiation (UV), tangential light and digital radiography. Expanding more the possibilities of analysis, new capabilities were added using portable equipment such as Energy Dispersive X-Ray Fluorescence (ED-XRF) and Raman Spectroscopy that can be used for analysis 'in situ' at the museums. The results of these analyzes are providing valuable information on the manufacturing process and have provided new information on objects of different University of Sao Paulo museums. Improving the arsenal of cultural heritage analysis it was recently constructed an 3D robotic stage for the precise positioning of samples in the external beam setup

  4. Cellular Automata Models Applied to the Study of Landslide Dynamics

    Liucci, Luisa; Melelli, Laura; Suteanu, Cristian

    2015-04-01

    Landslides are caused by complex processes controlled by the interaction of numerous factors. Increasing efforts are being made to understand the spatial and temporal evolution of this phenomenon, and the use of remote sensing data is making significant contributions in improving forecast. This paper studies landslides seen as complex dynamic systems, in order to investigate their potential Self Organized Critical (SOC) behavior, and in particular, scale-invariant aspects of processes governing the spatial development of landslides and their temporal evolution, as well as the mechanisms involved in driving the system and keeping it in a critical state. For this purpose, we build Cellular Automata Models, which have been shown to be capable of reproducing the complexity of real world features using a small number of variables and simple rules, thus allowing for the reduction of the number of input parameters commonly used in the study of processes governing landslide evolution, such as those linked to the geomechanical properties of soils. This type of models has already been successfully applied in studying the dynamics of other natural hazards, such as earthquakes and forest fires. The basic structure of the model is composed of three modules: (i) An initialization module, which defines the topographic surface at time zero as a grid of square cells, each described by an altitude value; the surface is acquired from real Digital Elevation Models (DEMs). (ii) A transition function, which defines the rules used by the model to update the state of the system at each iteration. The rules use a stability criterion based on the slope angle and introduce a variable describing the weakening of the material over time, caused for example by rainfall. The weakening brings some sites of the system out of equilibrium thus causing the triggering of landslides, which propagate within the system through local interactions between neighboring cells. By using different rates of

    Ji, Xue-Yuan; Wang, Yi-Li; Feng, Jing

    2012-12-01

    For an electro-dewatering process of activated sludge (AS), the effect of pH and conductivity of AS, flocculation conditioning and operation factors of horizontal electric field (voltage magnitude, method of applying electric field and distance between plates) were investigated, and the corresponding optimum electro-dewatering conditions were also obtained. The results showed that the best electro-dewatering effect was achieved for AS without change of its pH value (6.93) and conductivity (1.46 mS x cm(-1)). CPAM conditioning could lead to the increase of 30%-40% in the dewatering rate and accelerate the dewatering process, whereas a slight increase in the electro-dewatering rate. The electro-dewatering rate for conditioned AS reached 83.12% during an electric field applied period of 60 minutes, while this rate for original AS could be 75.31% even the electric field applied period extended to 120 minutes. The delay of applying the electric field had an inhibition effect on the AS electro-dewatering rate. Moreover, the optimum conditions for AS electro-dewatering were followed: CPAM dose of 9 g x kg(-1), electric field strength of 600 V x m(-1), distance between the two plates of 40 mm, dehydration time of 60 minutes. Under above optimum conditions the AS electro-dewatering rate could approach to 85.33% and the moisture content in AS decreased from 99.30% to 95.15% accordingly.

    Case studies can be useful in assessing and learning lessons from emergency situations. In this paper, different uses for disaster case studies, are explored with identification of potential pitfalls that should be avoided. In addition, ways to improve the rigor and significance of case studies are suggested. Case studies can be used as examples or as a research tool. If conducted properly, they can provide robust and compelling results. It is argued that sharing a common guide to conducting and writing case studies among all disaster risk reduction professionals could improve the quality of case study reports and thereby strengthen their value in advancing the prevention, preparedness, and management of disasters and emergencies.

    2000-09-01

    Spatiotemporal chaos control by applying local feedback injections is investigated analytically. The influence of gradient force on the controllability is investigated. It is shown that as the gradient force of the system is larger than a critical value, local control can reach very high efficiency to drive the turbulent system of infinite size to a regular target state by using a single control signal. The complex Ginzburg-Landau equation is used as a model to confirm the above analysis, and a four-wave-mixing mode is revealed to determine the dynamical behavior of the controlled system at the onset of instability.

    2015-12-01

    There is growing appreciation that process improvement holds promise for improving quality and efficiency across the translational research continuum but frameworks for such programs are not often described. The purpose of this paper is to present a framework and case examples of a Research Process Improvement Program implemented at Tufts CTSI. To promote research process improvement, we developed online training seminars, workshops, and in-person consultation models to describe core process improvement principles and methods, demonstrate the use of improvement tools, and illustrate the application of these methods in case examples. We implemented these methods, as well as relational coordination theory, with junior researchers, pilot funding awardees, our CTRC, and CTSI resource and service providers. The program focuses on capacity building to address common process problems and quality gaps that threaten the efficient, timely and successful completion of clinical and translational studies.

    Full Text Available Concentrated Photovoltaics (CPV, once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    2011-01-01

    Full Text Available Problem statement: Research on father-daughter succession in family businesses has only recently begun to get some traction. Still, examples of these situations often elude researchers. Futhermore, there has not been adequate attention paid to how children are raised in family businesses and how they learn to be entrepreneurial. Approach: This study outlines a father-daughter succession case in this unique American setting-the Appalachian Mountains of West Virginia. West Virginia offers an opportunity to examine family businesses embedded in the Appalachian culture-one where much of the popular and scholarly literature contend that deficiencies have contributed to, or reinforced, economic poverty and backwardness. These ideals are now being challenged and this case offers evidence of reversal. We also use the Bernelli 5+5+5 Model as a lens through which to examine the daughter’s entrepreneurial growth in this case. Results: The Bernelli 5+5+5 Model allowed us to structure the daughter’s experiences and better understand how she got to be such a successful successor. Conclusion/Recommendations: We recommend that the Bernelli 5+5+5 Model be used as a framework to view succession in family businesses. The Model also serves as a lens through which to view and better understand how children raised in family businesses become more successful entrepreneurs as adults.

    2013-04-01

    The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

  7. Optical Trapping Techniques Applied to the Study of Cell Membranes

    Science.gov (United States)

    Morss, Andrew J.

    Optical tweezers allow for manipulating micron-sized objects using pN level optical forces. In this work, we use an optical trapping setup to aid in three separate experiments, all related to the physics of the cellular membrane. In the first experiment, in conjunction with Brian Henslee, we use optical tweezers to allow for precise positioning and control of cells in suspension to evaluate the cell size dependence of electroporation. Theory predicts that all cells porate at a transmembrane potential VTMof roughly 1 V. The Schwann equation predicts that the transmembrane potential depends linearly on the cell radius r, thus predicting that cells should porate at threshold electric fields that go as 1/r. The threshold field required to induce poration is determined by applying a low voltage pulse to the cell and then applying additional pulses of greater and greater magnitude, checking for poration at each step using propidium iodide dye. We find that, contrary to expectations, cells do not porate at a constant value of the transmembrane potential but at a constant value of the electric field which we find to be 692 V/cm for K562 cells. Delivering precise dosages of nanoparticles into cells is of importance for assessing toxicity of nanoparticles or for genetic research. In the second experiment, we conduct nano-electroporation—a novel method of applying precise doses of transfection agents to cells—by using optical tweezers in conjunction with a confocal microscope to manipulate cells into contact with 100 nm wide nanochannels. This work was done in collaboration with Pouyan Boukany of Dr. Lee's group. The small cross sectional area of these nano channels means that the electric field within them is extremely large, 60 MV/m, which allows them to electrophoretically drive transfection agents into the cell. We find that nano electroporation results in excellent dose control (to within 10% in our experiments) compared to bulk electroporation. We also find that

  9. Droplet evaporation study applied to DNA chip manufacturing.

    Science.gov (United States)

    Dugas, Vincent; Broutin, Jérôme; Souteyrand, Eliane

    2005-09-27

    DNA chips are potentially powerful technologies for genotyping and gene expression profiling that rely on comparative analyses of up to thousands of "spots of analysis" on a glass support. The spot quality throughout the support influences spot-to-spot variations within an array and the repeatability of data across experiments. For glass slide DNA microarrays, droplets of DNA solution are deposited on functionalized glass slides and left to react through complete evaporation of the droplet. On hydrophobic flat surfaces, different modes of droplet evaporation can be attained. Under atmospheric pressure, water droplets tend to evaporate under two main regimes. Initially, the droplet flattens with a constant contact area, and then the droplet shrinks at a constant contact angle. As a result, the diameter and morphology of thousands of spots on microarrays are not uniform. This leads to poor and unreliable data processing results. In this work, we report the evaporation of an aqueous solution under a constant contact area mode. Evaporation under reduced pressure and the effect of reagent additives to the solution have been investigated. Video microscopy and digital image analysis techniques were applied to monitor the evaporation of the droplets. A mixture of surfactants was developed to maintain a constant area regime during evaporation and to form homogeneous spots. The control of some physicochemical properties (wetting, evaporation rate) of the droplet allows the formation of well-controlled spots compatible with DNA grafting. The influence of surfactant molecules on the mechanisms of evaporation is also discussed.

    Dynamic programming is typically applied to optimization problems. As the analytical solutions are generally very difficult, chosen software tools are used widely. These software packages are often third-party products bound for standard simulation software tools on the market. As typical examples of such tools, TOMLAB and DYNOPT could be effectively applied for solution of problems of dynamic programming. DYNOPT will be presented in this paper due to its licensing policy (free product under GPL) and simplicity of use. DYNOPT is a set of MATLAB functions for determination of optimal control trajectory by given description of the process, the cost to be minimized, subject to equality and inequality constraints, using orthogonal collocation on finite elements method. The actual optimal control problem is solved by complete parameterization both the control and the state profile vector. It is assumed, that the optimized dynamic model may be described by a set of ordinary differential equations (ODEs) or differential-algebraic equations (DAEs). This collection of functions extends the capability of the MATLAB Optimization Tool-box. The paper will introduce use of DYNOPT in the field of dynamic optimization problems by means of case studies regarding chosen laboratory physical educational models.

  14. Building Energy Information Systems: User Case Studies

    Energy Technology Data Exchange (ETDEWEB)

    Granderson, Jessica; Piette, Mary Ann; Ghatikar, Girish

    2010-03-22

    Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

    This manuscript provides a review of the clinical case study within the field of psychoanalytic and psychodynamic treatment. The method has been contested for methodological reasons and because it would contribute to theoretical pluralism in the field. We summarize how the case study method is being applied in different schools of psychoanalysis, and we clarify the unique strengths of this method and areas for improvement. Finally, based on the literature and on our own experience with case study research, we come to formulate nine guidelines for future case study authors: (1) basic information to include, (2) clarification of the motivation to select a particular patient, (3) information about informed consent and disguise, (4) patient background and context of referral or self-referral, (5) patient's narrative, therapist's observations and interpretations, (6) interpretative heuristics, (7) reflexivity and counter-transference, (8) leaving room for interpretation, and (9) answering the research question, and comparison with other cases.

    The ocean floor is one of the main accumulation sites of marine debris. The study of this kind of debris still lags behind that of shorelines. It is necessary to identify the methods used to evaluate this debris and how the results are presented and interpreted. From the available literature on benthic marine debris (26 studies), six sampling methods were registered: bottom trawl net, sonar, submersible, snorkeling, scuba diving and manta tow. The most frequent method used was bottom trawl net, followed by the three methods of diving. The majority of the debris was classified according to their former use and the results usually expressed as items per unity of area. To facilitate comparisons of the contamination levels among sites and regions some standardization requirements are suggested.

    A computational model has been developed in order to simulate the thermal and electric behavior of thermoelectric generators. This model solves the nonlinear system of equations of the thermoelectric and heat transfer equations. The inputs of the program are the thermoelectric parameters as a function of temperature and the boundary conditions, (room temperature and residual heat flux). The outputs are the temperature values of all the elements forming the thermoelectric generator, (performance, electric power, voltage and electric current generated). The model solves the equation system using the finite difference method and semi-empirical expressions for the convection coefficients. A thermoelectric electric power generation test bench has been built in order to validate and determine the accuracy of the computational model, which maximum error is lower than 5%. The objective of this study is to create a design tool that allows us to solve the system of equations involved in the electric generation process without needing to impose boundary conditions that are not known in the design phase, such as the temperature of the Peltier modules. With the computational model, we study the influence of the heat flux supplied as well as the room temperature on the electric power generated. (author)

    Flavonoid are a large and important class of naturally occurring, low molecular weight benzo-{gamma}-pyrone derivatives which are reported to have a myriad of biological activities, but the study on the active sites of flavonoids is still ambiguous. In this paper, rutin, quercetin and baicalin have been selected as model compounds. It is well known that rutin is used in inhibiting arteriosclerosis and baicalin is antibacterial and antiviral. They have similar basic structure, but their medicinal properties are so different, why? As most flavonoids contain carbonyl group, which can capture electron effectively, we predict that flavonoids can capture electron to form radical anion. The formation of anion radical may have influence on the mitochondrial electron transport chain. The difference in the ability of forming anion radical may cause the difference in their medicinal effects. (author)

    The technical feasibility and performance of photocatalytic degradation of four water-soluble pesticides (diuron, imidacloprid, formetanate and methomyl) have been studied at pilot scale in two well-defined systems which are of special interest because natural-solar UV light can be used for them: heterogeneous photocatalysis with titanium dioxide and homogeneous photocatalysis by photo-Fenton. The pilot plant is made up of compound parabolic collectors specially designed for solar photocatalytic applications. The initial concentration tested with imidacloprid, formetanate and methomyl was 50 and 30 mg/l with diuron, and the catalyst concentrations were 200 mg/l and 0.05 mM with TiO{sub 2} and iron, respectively. Total disappearance of the parent compounds, 90% mineralisation and toxicity reduction below the threshold (EC{sub 50}) have been attained with all pesticides tested. All these results have contributed to an evaluation of photocatalytic treatment capacity and comments on the main parameters of TiO{sub 2} and Fe separation from the treated water. (author)

    Full Text Available Abstract Background Biological databases and pathway knowledgebases are proliferating rapidly. We are developing software tools for computer-aided hypothesis design and evaluation, and we would like our tools to take advantage of the information stored in these repositories. But before we can reliably use a pathway knowledgebase as a data source, we need to proofread it to ensure that it can fully support computer-aided information integration and inference. Results We design a series of logical tests to detect potential problems we might encounter using a particular knowledgebase, the Reactome database, with a particular computer-aided hypothesis evaluation tool, HyBrow. We develop an explicit formal language from the language implicit in the Reactome data format and specify a logic to evaluate models expressed using this language. We use the formalism of finite model theory in this work. We then use this logic to formulate tests for desirable properties (such as completeness, consistency, and well-formedness for pathways stored in Reactome. We apply these tests to the publicly available Reactome releases (releases 10 through 14 and compare the results, which highlight Reactome's steady improvement in terms of decreasing inconsistencies. We also investigate and discuss Reactome's potential for supporting computer-aided inference tools. Conclusion The case study described in this work demonstrates that it is possible to use our model theory based approach to identify problems one might encounter using a knowledgebase to support hypothesis evaluation tools. The methodology we use is general and is in no way restricted to the specific knowledgebase employed in this case study. Future application of this methodology will enable us to compare pathway resources with respect to the generic properties such resources will need to possess if they are to support automated reasoning.

  16. The Hack's law applied to young volcanic basin: the Tahiti case

    We study the channel morphology over the Tahiti island from the Hack’s law perspective. The Hack’s law is an empirical power relationship between basin drainage area and the length of its main channel. It had also been shown that drainage area becomes more elongate with increasing basin size. For typical continental basins, the exponent value lies between 0.47 for basins larger than 260,000 km2 and 0.7 for those spanning less than 20,720 km2 (Muller, 1973). In Tahiti, we extracted 27 principal basins ranging from 7 km2 to 90 km2 from a Digital Terrain Model of the island with a 5 m-resolution. We demonstrate that the Hack’s law still apply for such small basins (correlation coefficient R2=0.7) with an exponent value being approximately 0.5. It appears that the exponent value is influenced by the local geomorphic condition, and does not follow the previous study results (the exponent value decreases with increasing drainage area.) Our exponent value matches the result found w.r.t. debris-flow basins of China for drainage areas less than 100 km2 (Li et al., 2008). Otherwise, the young volcanic basins of Tahiti do not become longer and narrower with increasing basin size (R2=0.1). Besides, there is no correlation between the basin area and the basin convexity (R2=0). This means that there is no statistical change in basin shape with basin size. We present also the drainage area-slope relationship with respect to sediment or transport-limited processes. Key words: Hack’s law, channel morphology, DTM

    Bisulca, Christina

    The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

    2003-01-01

    Full Text Available In 1887, in answer to railroad abuses of monopoly power, Congress passed the Interstate Commerce Act, which created the Interstate Commerce Commission (ICC. In the next decade the Commission’s powers were considerably diminished by a series of Supreme Court decisions in cases in which the railroads appealed ICC rulings. In only one case during this period, the United States v. Trans-Missouri Freight Association, did the Court uphold an ICC decision. This case was primarily about collaborative ratemaking in rate bureaus but covered several larger issues, especially the possibly conflicting jurisdictions of the Sherman Act and the Interstate Commerce Act.

  5. Leishmaniasis in dogs: Case study

    2009-01-01

    Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

    2009-01-01

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

  7. From single-case studies to practice-based knowledge: aggregating and synthesizing case studies.

    Iwakabe, Shigeru; Gazzola, Nicola

    2009-07-01

    Recent developments in case study methodology reflect a rising interest that clinicians and researchers share in building a clinically useful and empirically sound knowledge base from single-case studies. The present article describes three types of single-case studies (clinical, experimental, systematic) and examines their potential contributions to psychotherapy research. It then lays out three ways in which single-case studies can be aggregated and synthesized to enhance clinical understanding: (a) a case database that allows clinicians to efficiently search for relevant cases, (b) a metasynthesis of single-case studies that integrates common themes across similar cases, and (c) an individual case comparison method in which closely matched cases are compared to identify both therapeutic and hindering processes.

  8. A review of studies applying environmental impact assessment methods on fruit production systems.

    Cerutti, Alessandro K; Bruun, Sander; Beccaro, Gabriele L; Bounous, Giancarlo

    2011-10-01

    Although many aspects of environmental accounting methodologies in food production have already been investigated, the application of environmental indicators in the fruit sector is still rare and no consensus can be found on the preferred method. On the contrary, widely diverging approaches have been taken to several aspects of the analyses, such as data collection, handling of scaling issues, and goal and scope definition. This paper reviews studies assessing the sustainability or environmental impacts of fruit production under different conditions and identifies aspects of fruit production that are of environmental importance. Four environmental assessment methods which may be applied to assess fruit production systems are evaluated, namely Life Cycle Assessment, Ecological Footprint Analysis, Emergy Analysis and Energy Balance. In the 22 peer-reviewed journal articles and two conference articles applying one of these methods in the fruit sector that were included in this review, a total of 26 applications of environmental impact assessment methods are described. These applications differ concerning e.g. overall objective, set of environmental issues considered, definition of system boundaries and calculation algorithms. Due to the relatively high variability in study cases and approaches, it was not possible to identify any one method as being better than the others. However, remarks on methodologies and suggestions for standardisation are given and the environmental burdens of fruit systems are highlighted.

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or "Classical psychoanalysis" dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals.

    Full Text Available Risk management is a decision-making process involving considerations of political, social, economic and engineering factors with relevant risk assessments relating to a potential hazard. In the last decade, a number of risk management tools are introduced and employed to manage and minimize the uncertainty and threats realization to the organizations. However, the focus of these methodologies are different; in which companies need to adopt various risk management principles to visualize a full picture of the organizational risk level. Regarding to this, this paper presents a new approach of risk management that integrates Hierarchical Holographic Modeling (HHM, Enterprise Risk Management (ERM and Business Recovery Planning (BCP for identifying and assessing risks as well as managing the consequences of realized residual risks. To illustrate the procedures of the proposed methodology, a logistic company ABC Limited is chosen to serve as a case study Through applying HHM and ERM to investigate and assess the risk, ABC Limited can be better evaluated the potential risks and then took the responsive actions (e.g. BCP to handle the risks and crisis in near future.

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

    This paper discusses the use of bioremediation as an effective method to clean up diesel-range hydrocarbon spills in northern latitudes. The results of a laboratory study of microbial degradation of hydrocarbons under simulated arctic conditions showed that bioremediation can be effective in cold climates and led to the implementation of a large-scale field program. The results of 3 years of field testing have led to a significant reduction in diesel-range hydrocarbon concentrations in the contaminated area.

    2008-06-01

    Full Text Available The application of a methodology that proposes the use of spectral methods to inform the development of statistical forecasting models for cholera case data is explored in this paper. The seasonal behaviour of the target variable (cholera cases is analysed using singular spectrum analysis followed by spectrum estimation using the maximum entropy method. This seasonal behaviour is compared to that of environmental variables (rainfall and temperature. The spectral analysis is refined by means of a cross-wavelet technique, which is used to compute lead times for co-varying variables, and suggests transformations that enhance co-varying behaviour. Several statistical modelling techniques, including generalised linear models, ARIMA time series modelling, and dynamic regression are investigated for the purpose of developing a cholera cases forecast model fed by environmental variables. The analyses are demonstrated on data collected from Beira, Mozambique. Dynamic regression was found to be the preferred forecasting method for this data set.

    Full Text Available Higher education students usually ask for more training based on case studies. This was addressed by designing a specific food safety module (24 hours in which students were shown how to predict microbiological risks in food products i.e. they were asked to determine product shelf-life according to product formulation, preservation methods and consumption habits using predictive microbiology tools. Working groups of four students first identified the main microbiological hazards associated with a specific product. To perform this task, they were given several documents including guides for good hygiene practices, reviews on microbiological hazards in the food sector, flow sheets, etc…  After three-hours of work, the working groups prepared and gave an oral presentation in front of their classmates and professors. This raised comments and discussion that allowed students to adjust their conclusions before beginning the next step of their work. This second step consisted in the evaluation of the safety risk associated with the two major microbiological hazards of the product studied, using predictive microbiology. Students then attended a general lecture on the different tools of predictive microbiology and tutorials (6 hours that made them familiar with the modelling of bacterial growth or inactivation. They applied these tools (9 hours to predict the shelf-life of the studied product according to various scenarios of preservation (refrigeration, water activity, concentration of salt or acid, modified atmosphere, etc… and/or consumption procedures (cooking. The module was concluded by oral presentations of each working group and included student evaluation (3 hours.

    Full Text Available This research reviews the literature on case study as a strategic qualitative research methodology. Although case studies have been criticised by some authors as lacking scientific rigour and do not address generalizability, this research, however, reiterated its appropriateness when dealing with a process or a complex real-life activities in great-depth. Case study has been commonly used in social science fields like sociology, industrial relations and anthropology eventhough generally was considered an underutilized strategy. Hence, this research explained the general concept of a case study, strengths and weaknesses of using this method knowing that theoretically case is exciting and data rich. Based on a study of four organizations and the researcher’s own experience, this article described matters on how case study was undertaken, gaining excess to those organizations and the systematic process of data collection and triangulation (multiple techniques. It was noted that combining multiple techniques for elicitng data in case study research actually strengthens and confirmed results.

    The application of a magnet to a pacemaker (intended to cause asynchronous pacing) or implanted cardioverter defibrillator (intended to prevent shocks) during surgery without a clear understanding of actual magnet function(s) or precautions can have unexpected, untoward, or harmful consequences. In this report, we present 3 cases in which inadequate assessment of cardiac implanted electronic device (CIED) function, coupled with magnet application, contributed to or resulted in inappropriate antitachycardia pacing or shocks, CIED damage, or patient injury. Although these cases might be rare, they reinforce the need for a timely, detailed preoperative review of CIED function and programming as recommended by the American Society of Anesthesiologists and the Heart Rhythm Society.

    Shevory, T C

    1986-01-01

    John Rawls's Theory of Justice has been widely and correctly recognized as a tremendous intellectual accomplishment. It has been applauded as a comprehensive and satisfying approach to the problem of defining justice. Health policy analysts and medical ethicists have thus been inspired to apply Rawls's principles to various health care issues. The result has not been greater coherence in approaches to issues of policy and ethics, leading the author to question the validity of Rawls's analytical approach.

    Full Text Available Modern educational technologies are based on competence approach and focus on the future professional activity. Case study is one of the most significant technologies in modern higher education. The basic concepts used in the case study method are a “situation” and an “analysis”, as well as their derivative - “analysis of the situation”. The case study method of is one of the best tools for gaining experience, as it investigates practical situations that occur in managerial job. It combines theoretical knowledge with the analysis of the actual practical experience in accordance with a major. Doing case studies students read the description of the situation and offer divergent projects of managerial decisions that could be used by real managers dealing with the problem posed by the case study author. Answers to the questions posed in the case description are not given, as a rule, since the main purpose in the case analysis is to organize a discussion in the classroom or provoke speculations of those who do the self-study.

    Purpose: The aim of this work was to analyse all the applied movements when extracting healthy upper and lower jaw premolars for orthodontic purposes. The authors wanted to demonstrate that the different bone densities of the mandible and maxilla are not a significant parameter when related to the extraction force applied. The buccal and palatal rocking movements, plus the twisting movements were also measured in this in-vivo study during premolar extraction for orthodontic purposes. Methods: The physical strains or forces transferred onto the teeth during extraction are the following three movements: gripping, twisting, and traction. A strain measurement gauge was attached onto an ordinary dentistry plier. The strain measurement gauge was constituted with an extensimetric washer with three 45º grids. The system operation was correlated to the variation of electrical resistance. Results: The variations of resistance (∆R) and all the different forces applied to the teeth (∆V) were recorded by a computerized system. Data results were processed through Microsoft Excel. The results underlined the stress distribution on the extracted teeth during gripping, twisting and flexion. Conclusions: The obtained data showed that the strength required to effect teeth extraction is not influenced by the quality of the bone but is instead influenced by the shape of the tooth’s root.

    Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient``s high risk of strokes and hemorrhaging prompted investigation by a {sup 99}mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome.

    Full Text Available This India is the Fifth largest producer of Electricalenergy in the world. Despite such achievements the gapbetween demand and supply of electrical energy is increasingevery year and power sector is highly capital – intensive. Thusthe deficit in installed capacity was nearly 10000MWper year.So the gap between demand and supply is continuouslyincreasing day by day. An energy audit is a study of a plant orfacility to determine how and where energy is used and toidentify methods for energy savings. The opportunities lie inthe use of existing renewable energy technologies, greaterefforts at energy efficiency and the dissemination of thesetechnologies and options. This thesis provides an overview of ageneral energy conservation measures (ECMs that can becommonly recommended for NIT Hamirpur. It should be notedthat the Energy auidut presented in this paper does not pretendto be exhaustive nor comprehensive. It provides merely toindicate some of the options that energy auditor can considerwhen performing an analysis of this institute. Energyconservation and exploration of new energy avenues are thewell accepted solution to fulfil the demand in future. The totalcost of energy plays a vital role in determining the product costof a commodity. Therefore the identification of potential energysavings and implementation for a given institutional facility isunimportant to ensure its competitive advantage over otherinstitute.

    In the past three decades, philosophers have delved into applied ethics, pursuing a surprisingly wide range of practically oriented normative questions, and a number of fields of applied ethical research and teaching are flourishing. There have, however, been few comparative studies of different fields in applied ethics, but such studies can, I believe, teach us something. Accordingly, this essay compares and contrasts business ethics and military ethics as distinct disciplinar...

  18. Predatory violence aiming at relief in a case of mass murder: Meloy's criteria for applied forensic practice.

    Science.gov (United States)

    Declercq, Frédéric; Audenaert, Kurt

    2011-01-01

    Mass murder is the result of the complex interaction of several factors. What seems ubiquitous within mass murder are extreme feelings of anger and revenge. Yet despite these intense affective states, mass murders are, as a rule, not behaviorally impulsive, but rather prepared. The presence of extreme hate and anger evokes an impulsive outburst of rage, whereas planning and premeditation point in the direction of a cognitive, rather unemotional deed. This inconsistency is also reflected in reports of offenders' emotional states during the execution of their crimes: while some mass murderers have been described as calm, focused and emotionless during the events, others have shown signs of hostility, confusion, and distress. Considering mass murder from the perspective of its violence mode might shed some light on its nature and dynamics. With respect to the differentiation between affective and predatory violence, Meloy (1988) developed a model for applied forensic practice. The fully documented case of mass murder discussed in this study contains nine indices of predatory violence and one of affective violence. Furious affects of hate and anger were present but appeared to precede the cold-blooded killings. As a matter of fact, it is argued that the offender carried out the predatory murder in order to alleviate the psychological tension and symptoms generated by these severe ego-dystonic affects. The offender thus didn't seem to strive for narcissistic gratification of omnipotence, but rather seemed to aim to solve a problem.

    Petro Andina Resources Ltd. together with Tandem Decision Solutions developed a strategic long range plan applying decision analysis methodology. The objective was to build a robust and fully integrated strategic plan that accomplishes company growth goals to set the strategic directions for the long range. The stochastic methodology and the Integrated Decision Management (IDM{sup TM}) staged approach allowed the company to visualize the associated value and risk of the different strategies while achieving organizational alignment, clarity of action and confidence in the path forward. A decision team involving jointly PAR representatives and Tandem consultants was established to carry out this four month project. Discovery and framing sessions allow the team to disrupt the status quo, discuss near and far reaching ideas and gather the building blocks from which creative strategic alternatives were developed. A comprehensive stochastic valuation model was developed to assess the potential value of each strategy applying simulation tools, sensitivity analysis tools and contingency planning techniques. Final insights and results have been used to populate the final strategic plan presented to the company board providing confidence to the team, assuring that the work embodies the best available ideas, data and expertise, and that the proposed strategy was ready to be elaborated into an optimized course of action.

    Science.gov (United States)

    Bittmann, Stefan; Krüger, Carsten

    Benzocaine is a widely used topical anaesthetic and has been reported to cause toxic methaemoglobinaemia in otherwise healthy individuals with no predisposing risk factors. This article reports on a rare case of benzocaine-induced methaemoglobinaemia following adenotonsillectomy in a 5-year-old girl. Topical benzocaine was applied orally for the relief of postoperative wound pain on the eighth postoperative day. Two hours after application, generalized cyanosis, mild dyspnoea and some degree of agitation developed. The methaemoglobin level was 38.5%. Treatment with methylene blue was initiated immediately. Symptoms completely disappeared 4 hours after initiation of methylene blue therapy. The further course was uneventful. Therefore, all health professionals should be aware that topical anaesthetics after surgery can induce methaemoglobinaemia in children, even after a prolonged interval, and especially when applied on wound surfaces.

    Full Text Available Keeping good professionals has been one of the main objectives of companies, especially those who add value and dedicate their time and efforts to achieve the company goals. In order to retain these professionals, companies have looked for new remunerations, besides the traditional one, known as strategic remuneration, along with a wide fringe of other benefits. In this way, the present study aims to identify the satisfaction level of its operational employees concerning the types of strategic remuneration and the package of benefits adopt by a multinational company in the metropolitan area of  Porto Alegre. The methodology presented in this monograph was based on a case study in the company mentioned before, which prefers not be identified. Theinformation was raised through some descriptive research of qualitative nature, through a semi-structured interview with an employee from the human resources area who clarified the key point for the study development and for the quantitative research. This research was applied through a questionnaire with operational employees and aims to identify if they know the strategic remuneration programs and the package of benefits offered by the company and also identify if they are used to participating in some of them.Reter bons profissionais, que agreguem valor e se dediquem ao alcance dos objetivos da empresa, vem sendo uma constante nas organizações.

    Full Text Available Bilingual education is one of the areas in contemporary education that brings out some important controversies (philosophical, conceptual, sociological, political, economical, etc. and thus calls for extensive and intensive debate. Bilingual education in Europe (and here the European Union countries are meant has gained a very different status, due to the general European policy of developing language diversity and promoting “European plurilingualism and multilingualism”. In Slovakia, one of the younger members of the EU, bilingual education became an extraordinarily popular instrument for the fulfilment of this task.  Since the specifically defined topic of bilingual education and its current status in Slovakia has not been studied and systematically reviewed yet, the research presented in this paper was designed as a single-phenomenon revelatory case study investigating seven research areas: reflection of bilingual education in school legislation and state pedagogical documents, purposes of bilingual education in Slovakia, its organization (levels and types of schools, foreign languages incorporated, teachers, structure of bilingual schools curricula, types of bilingual education applied at Slovak bilingual schools, and how bilingual education is both reflected in and saturated by the latest research findings. The conclusions presented in the paper were collected from multiple sources: state curriculum, statistical data published by the Slovak Ministry of Education or its partner institutions, international treaties on establishing and supporting bilingual sections of schools, bilingual schools curricula, interviews with school directors, teachers, and learners, direct observations at bilingual schools, research studies and research reports, etc. In the conclusion, bilingual education in Slovakia is identified as a unique, dynamically developing system which is both significantly shaped by the foreign language education policy promoted by

    Liquid suspensions of Active Pharmaceutical Ingredient powders are present as pharmaceutical dosage forms in the form of oral suspensions and injectables. We present two case studies, both dense (~ 30-40%) suspensions, in which the physical characterization of the product, specifically, particle size & shape and rheology were key to understanding the key product attributes as pertaining to the manufacturing process and to patient administration. For the one case study, an oral suspension, identifying variations in particle morphology during the wet milling of the product was key to the product understanding necessary to modify the milling process. Rheological measurements were applied as well. For the second case study, an injectable, results from different particle size measurement techniques and rheological measurements indicated the possibility of flocculation in a formulation. Additionally, measurements were obtained to assess the ``injectability'' of the product via rheometer and texture analyzer measurements and Poiseuille flow modeling. As a result, the relevant shear rate regime for this drug product administration was identified.

    2009-09-01

    Full Text Available Abstract Background In haplotype-based candidate gene studies a problem is that the genotype data are unphased, which results in haplotype ambiguity. The measure 1 quantifies haplotype predictability from genotype data. It is computed for each individual haplotype, and for a measure of global relative efficiency a minimum value is suggested. Alternatively, we developed methods directly based on the information content of haplotype frequency estimates to obtain global relative efficiency measures: and based on A- and D-optimality, respectively. All three methods are designed for single populations; they can be applied in cases only, controls only or the whole data. Therefore they are not necessarily optimal for haplotype testing in case-control studies. Results A new global relative efficiency measure was derived to maximize power of a simple test statistic that compares haplotype frequencies in cases and controls. Application to real data showed that our proposed method gave a clear and summarizing measure for the case-control study conducted. Additionally this measure might be used for selection of individuals, who have the highest potential for improving power by resolving phase ambiguity. Conclusion Instead of using relative efficiency measure for cases only, controls only or their combined data, we link uncertainty measure to case-control studies directly. Hence, our global efficiency measure might be useful to assess whether data are informative or have enough power for estimation of a specific haplotype risk.

    Full Text Available Background: Marital instability is affected by many factors. In Iran, socio-cultural and political limitations are obstacles for sexuality-related studies; therefore, insufficient information is available in this area. In the present research, we investigated the relationship between marital instability and sexual satisfaction among Iranian women. Materials and Methods: A case-control study was carried out to investigate women applying for divorce in comparison with our controls during 2011 to 2012 in Isfahan, Iran. Data gathering was done using a questionnaire including two parts: socio-demographic information and factors influencing sexual satisfaction. Larson Inventory of Sexual Satisfaction for determining sexual satisfaction was used to determine sexual satisfaction. Results: Divorce rate is significantly related to sexual satisfaction (p=0.009. There were also significant relationships between sexual satisfaction and the following variables: age, economic status, amount of income, duration of marriage, number of children, housing, alcohol/drug abuse by spouse, being beaten by spouse, compulsory marriage, second marriage of spouse, and being happy with current partner. Conclusion: Sexual satisfaction plays an important role in marital stability of Iranian women. Thus, development of practical strategies in order to provide cultural intervention is needed to improve Iranian couples’ awareness of their sexual relationship. Indeed, trainings in communication skills through sexual encounters are essential.

    Full Text Available The basic information for computing the quantitative statistical indicators, that characterize the demand of industrial products and services are collected by the national statistics organizations, through a series of statistical surveys (most of them periodical and partial. The source for data we used in the present paper is an statistical investigation organized by the National Institute of Statistics, "Family budgets survey" that allows to collect information regarding the households composition, income, expenditure, consumption and other aspects of population living standard. In 2005, in Romania, a person spent monthly in average 391,2 RON, meaning about 115,1 Euros for purchasing the consumed food products and beverage, as well as non-foods products, services, investments and other taxes. 23% of this sum was spent for purchasing the consumed food products and beverages, 21.6% of the total sum was spent for purchasing non-food goods and 18,1%  for payment of different services. There is a discrepancy between the different development regions in Romania, regarding total households expenditure composition. For this reason, in the present paper we applied statistical methods for ranking the various development regions in Romania, using the share of householdsí expenditure on categories of products and services as ranking criteria.

    The vitreous of three patients with asteroïd hyalosis (average age: 57 years) was obtained by a two-hand closed pars plana vitrectomy. Asteroïd hyalosis was associated with alcoholic neuropathy in the first case, long standing retinal detachment in the second case, and diabetes mellitus in the third case. The visual acuity before and after the surgical procedure improved from 1.2/6 to 6/6 in the first case, from light perception to 0.3/6 in the second case, from 0.6/6 to 4.8/6 in the third case. The vitreous was studied by different ultrastructural technics : transmission electron microscopy (T.E.M.) scanning electron microscopy (S.E.M.) and electron diffraction X ray analysis (E.D.A.X.). By S.E.M. the asteroïd bodies appeared as rounded structures with an irregular surface connected to each other by fibrous strands among sodium chloride crystals. No cellular remnants were observed. By T.E.M. the asteroïd bodies were composed of interwinned ribbons of multilaminar membranes with a periodicity (10 to 60 A) characteristic of complex lipids, especially phospholipids. At the edge of the ribbons there were dots and sometimes clumps of opaque material that tended to crack out of the specimen with the heat of the electron beam. T.E.M. study disclosed the irregular disposition of the calcific bodies. By E.D.A.X. the calcific composition of the rounded structures could be determined : calcium and phosphorus were the main elements detectable in asteroïd bodies of all sizes for all three patients. The average calcium counts for the three successive cases were : 18, 30, 43 and for phosphorus : 9, 14, 26. Potassium was found in the first case, and sulfur in the third case.(ABSTRACT TRUNCATED AT 250 WORDS)

    Molecular dynamics (MD) simulations are performed to study the correlation between electron irradiation defects and applied stress in graphene. The electron irradiation effect is introduced by the binary collision model in the MD simulation. By applying a tensile stress to graphene, the number of adatom-vacancy (AV) and Stone–Wales (SW) defects increase under electron irradiation, while the number of single-vacancy defects is not noticeably affected by the applied stress. Both the activation and formation energies of an AV defect and the activation energy of an SW defect decrease when a tensile stress is applied to graphene. Applying tensile stress also relaxes the compression stress associated with SW defect formation. These effects induced by the applied stress cause the increase in AV and SW defect formation under electron irradiation.

    Full Text Available This paper aims to propose and validate a model based on the Theory of Planned Behavior in order to explain consumers’ pro-environmental behaviour regarding energy conservation. The model was constructed using the five variables from Ajzen’s Theory of Planned Behavior (TPB (behaviour, intention, perceived behavioural control, subjective norms and attitude to which a variable adapted from Schwartz’s Norm Activation Theory (NAT was added (“awareness of the consequences and the need” in order to create a unique model adapted for the special case of energy conservation behaviour. Further, a survey was conducted and the data collected were analysed using structural equation modelling. The first step of data analysis confirmed that all the constructs have good reliability, internal consistency and validity. The results of the structural equation analysis validated the proposed model, with all the model fit and quality indices having very good values. In the analysis of consumers’ proenvironmental behaviour regarding energy conservation and their intention to behave in a proenvironmental manner, this model proved to have a strong predictive power. Five of seven hypotheses were validated, the newly introduced variable proving to be a success. The proposed model is unique and will offer companies and organizations a valuable green marketing tool which can be used in the fight for environment protection and energy conservation.

    Full Text Available The need to produce more sustainable buildings has been influencing the design decisions all over the world. That’s why it is imperative, in Brazil, the development of strategies and method to aid the decision making during the design process, focused on high quality environmental. This paper presents a decision support tool based on the principles of sustainable construction developed by the Project, Architecture and Sustainability Research Group (GPAS of Federal University of Rio de Janeiro – Brazil. The methodology has been developed for the selection of a preliminary design of a laboratory to be built at Rio Technology Park at the University campus. The support provided by GPAS occurred in three stages: the elaboration of the Reference Guide for the competitors, the development of a methodology to evaluate the proposed solutions (based on environmental performance criteria and the assistance of the members of jury in the trial phase. The theoretical framework was based upon the concepts of the bioclimatic architecture, the procedures specified by the certification HQE® (Haute Qualité Environnementale and the method suggested by the ADDENDA® architecture office. The success of this experience points out the possibility to future application in similar cases.

    2009-12-01

    Full Text Available It is often difficult to provide students in introductory science courses with opportunities that mimic the investigative learning experience of doing research. This is particularly true in microbiology courses where advanced microscopy techniques are expensive and difficult to do. To that end, we developed three computer-based case studies around real-life scenarios. Our goals were to: (i improve students’ understanding of advanced microscopic techniques, (ii give students practice analyzing and interpreting data, and (iii model a scientific approach to how these techniques are applied to current issues in microbiology. Each case requires students to use references and interpret actual microscopic images, thus giving them a more realistic experience than we could previously provide. We analyzed student learning and perceptions to these case studies. After doing the case studies, students were more able to apply microscopic methods to a realistic problem, thus demonstrating an understanding of how the methods are used. Students appreciated the intellectual challenges presented by having to interpret and analyze actual microscopic images. This approach has allowed us to introduce new areas of content to our course and to stimulate critical thinking skills, a difficult task in a large introductory microbiology course.

    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

    2014-01-01

    Full Text Available A review of literature indicates that there are different types of qualitative research methods such as action research, content analysis, ethnography, grounded theory, historical analysis, phenomenology and case study. However, which approach is to be used depends on several factors such as the nature and objectives of the research. The aim of this paper is to focus on the research methodology aspects of applying case study as a research approach and its relevance in tourism destination branding research specifically on a single case study (SCS context. There are arguments that the SCS is a weak research strategy. Some of the potentials or shortcomings highlighted in the literature include the primitive nature of SCS, flexibility of sample technique, data collection method and data analysis. Others include lack of rigour, reliability, validity, credibility of findings and generalisation. This paper has adopted content analysis of the literature on tourism destination branding. Findings indicate that the quality of SCS can be verified using specific case study tactics for four design tests such as validity (construct, internal and external; and reliability using the case study protocol. Theoretical implication suggests that SCS is an empirical enquiry use to understand complex phenomena and favoured by practitioners.

    2016-12-01

    Full Text Available This paper argues that both criminologists and lawyers need a far more philosophically robust account of joint action, notably as it relates to technical matters of intentionality and responsibility when dealing with joint criminal enterprise cases. Criminology seems unable to see beyond the superficiality of cultural explanations ill-suited to understanding matters of action. Law seems wedded to mystical notions of foresight. As regards the law there seems common agreement that joint enterprise prosecutions tend to over-criminalise secondary parties. This paper suggests that the current discussions around joint criminal enterprise will benefit from a critical engagement with analytical philosophy. The paper will examine a series of technical accounts of shared commitment and intention in order to explain the problems of joint criminal enterprise (multi-agent criminal activity. Este artículo defiende que tanto criminólogos como abogados necesitan ofrecer una acción conjunta más robusta, desde el punto de vista filosófico, especialmente en lo que se refiere a aspectos técnicos de intencionalidad y responsabilidad, al tratar casos de colaboración criminal. La criminología parece incapaz de ver más allá de la superficialidad de las explicaciones culturales, inadecuadas para entender cuestiones de acción. El derecho parece aliado con nociones místicas de previsión. En lo que respecta al derecho, parece que existe un consenso en que los fiscales de asociaciones de malhechores tienden a penalizar en exceso a los cómplices.

It takes as a case study two items commonly held to be synonyms -'actually' and 'in fact'- and shows considerable differences between the two in their interactional implementation: they are implicated in the prosecution of differing courses of action. Such cases argue that it is analytically more profitable to consider what a lexical item does in the context of talk than what it means.

    2007-07-01

    Full Text Available Documenting the presence and abundance of the neotropical mammals is the first step for understanding their population ecology, behavior and genetic dynamics in designing conservation plans. The combination of field research with molecular genetics techniques are new tools that provide valuable biological information avoiding the disturbance in the ecosystems, trying to minimize the human impact in the process to gather biological information. The objective of this paper is to review the available non invasive sampling techniques that have been used in Neotropical mammal studies to apply to determine the presence and abundance, population structure, sex ratio, taxonomic diagnostic using mitochondrial markers, and assessing genetic variability using nuclear markers. There are a wide range of non invasive sampling techniques used to determine the species identification that inhabit an area such as searching for tracks, feces, and carcasses. Other useful equipment is the camera traps that can generate an image bank that can be valuable to assess species presence and abundance by morphology. With recent advances in molecular biology, it is now possible to use the trace amounts of DNA in feces and amplify it to analyze the species diversity in an area, and the genetic variability at intraspecific level. This is particularly helpful in cases of sympatric and cryptic species in which morphology failed to diagnose the taxonomic status of several species of brocket deer of the genus Mazama.

    Necrotizing fasciitis represents a group of highly lethal infections characterized by rapidly progressing inflammation and necrosis. The aim of the study was to analyze the clinical profile, microbial flora, and predisposing risk factors in patients with necrotizing fasciitis. Lastly, we aimed to formulate a protocol for management of necrotizing fasciitis. Forty-eight cases of necrotizing fasciitis patients who reported to our hospital between April 2007 and September 2009 were included in the study. The commonest predisposing factors were age greater than 50 years (58 % cases) and diabetes mellitus (52 % cases). The commonest site involved was extremity (70.8 %). Majority of infections were polymicrobial (87.5 %). Repeated aggressive debridement was the commonest surgical procedure performed. Early and aggressive surgical debridement, often in multiple sittings, supplemented by appropriate antibiotics and supportive therapy, forms the key to a successful outcome in necrotizing fasciitis.

    Soil is a non-renewable resource with fundamental functions like filtering (e.g. water), storing (e.g. carbon), transforming (e.g. nutrients) and buffering (e.g. contamination). Degradation of soils is meanwhile not only to scientists a well known fact, also decision makers in politics have accepted this as a serious problem for several environmental aspects. National and international authorities have already worked out preservation and restoration strategies for soil degradation, though it is still work of active research how to put these strategies into real practice. But common to all strategies the description of soil state and dynamics is required as a base step. This includes collecting information from soils with methods ranging from direct soil sampling to remote applications. In an intermediate scale mobile geophysical methods are applied with the advantage of fast working progress but disadvantage of site specific calibration and interpretation issues. In the framework of the iSOIL project we present here some case studies for soil mapping performed using multiple geophysical methods. We will present examples of combined field measurements with EMI-, GPR-, magnetic and gammaspectrometric techniques carried out with the mobile multi-sensor-system of Kiel University (GER). Depending on soil type and actual environmental conditions, different methods show a different quality of information. With application of diverse methods we want to figure out, which methods or combination of methods will give the most reliable information concerning soil state and properties. To investigate the influence of varying material we performed mapping campaigns on field sites with sandy, loamy and loessy soils. Classification of measured or derived attributes show not only the lateral variability but also gives hints to a variation in the vertical distribution of soil material. For all soils of course soil water content can be a critical factor concerning a succesful

    Meningitis and/or encephalitis can pose a serious public health problem especially during outbreaks. A rapid and accurate diagnosis is important for effective earlier treatment. This study aimed to identify the possible microbial causes of meningitis and/or encephalitis cases. CSF and serum samples were collected from 322 patients who had signs and symptoms suggestive of meningitis and/or encephalitis. Out of 250 cases with confirmed clinical diagnosis, 83 (33.2%) were definitely diagnosed as bacterial meningitis and/or encephalitis cases (by using CSF culture, biochemical tests, latex agglutination test, and CSF stain), 17 (6.8%) were definitely diagnosed as having viral causes ( by viral isolation on tissue culture, PCR and ELISA), and one (0.4%) was diagnosed as fungal meningitis case (by India ink stain, culture, and biochemical tests). Also, there was one encephalitis case with positive serum ELISA IgM antibodies against Sandfly scilian virus. N. meningitidis, S. pneumonia and M. tuberculosis were the most frequently detected bacterial agents, while Enteroviruses, herpes simplex viruses and varicella zoster viruses were the most common viral agents encountered. Further studies are needed to assess the role of different microbial agents in CNS infections and their effective methods of diagnosis.

    Full Text Available BACKGROUND We have studied 200 patients of pleural fluid presenting to our tertiary care centre. Presence of cases of pleural fluid is a common presentation both in pulmonary and extrapulmonary diseases. We analysed the patients having both exudates and transudates and studied the results. MATERIALS AND METHODS We selected patients above 20 years of age and classified the patients with pleural fluid as having transudates and exudates. We studied the causes of transudates and exudates. A total of 200 patients are studied in this prospective study. Diagnosis of pleural exudates is made on the basis of Light’s criteria, chest x-ray, pleural fluid analysis, CT scan in selected patients, sputum examination, bronchoscopy and bronchial washings. Moribund and non-cooperative patients and HIV positives were excluded from the study. RESULTS Among the 200 patients, 91% have exudates. 9% have transudates by Light’s criteria. Tuberculosis is the commonest cause of effusions (64.83% followed by malignancy (13.73% and sympneumonic or parapneumonic effusions (9.89%. Pleural effusions occurred predominantly in males. Prevalence of diabetes Mellitus among cases of tuberculous pleural effusions is 13.56%. Tuberculous effusions are predominantly right-sided. CONCLUSION Predominant cases of pleural fluid are exudates. Commonest cause of pleural effusion is Tuberculosis followed by malignancy both pulmonary and extrapulmonary and sym. and parapneumonic effusions. Prevalence of Diabetes among Tuberculous pleural effusion cases is more or less same as in general population. Cough, expectoration fever, chest pain and breathlessness are the common symptoms occurring in three fourths of the patients of tuberculous pleural effusion. Most of the cases of Tuberculous effusion are above 30 years of age. In the diagnosis of tuberculous pleural effusion, Pleural fluid ADA is very important.

    Kavanaugh, K; Robertson, P A

    1999-01-01

    To date, investigators have not demonstrated a clear relationship between a parent's history of prior perinatal losses and intensity of grief response following a subsequent perinatal loss. Examining this relationship for low-income, African-American parents is important because they are a vulnerable population due to the high incidence of perinatal mortality in Blacks and their other life stressors that can impact on grief response and caring needs. The purpose of this case study was to examine the impact of recurrent perinatal loss on a low-income African-American parent. The research design for this study was case report, using interview data collected from a mother who had recently experienced her fourth perinatal loss, which occurred at twenty-five weeks of gestation. Transcripts from two open-ended interviews were analyzed. The theoretical framework used to guide analysis of this case study was Lazarus and Folkman's stress and coping theory. Results demonstrated that the prior perinatal losses did not appear as critical components of the way the mother responded to her most recent loss. Instead, perception of the care she received from healthcare providers and how that care related to her experiences with her one living child who was born at the same gestational age was an important determinant in how she responded to her loss. The results of this case study demonstrate the importance assessing a person's perception of their experience and those factors which contribute to the way they respond.

  15. Nanomaterial Case Studies: Nanoscale Titanium Dioxide ...

    Science.gov (United States)

    This draft document presents two case studies of nanoscale titanium dioxide (nano-TiO2) used (1) to remove arsenic from drinking water and (2) as an active ingredient in topical sunscreen. The draft case studies are organized around a comprehensive environmental assessment approach that combines a product life cycle framework with the risk assessment paradigm. The document does not draw conclusions about potential risks. Rather, the case studies are intended to help identify what needs to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. This draft document is part of a process that will inform the development of EPA’s research strategy to support nanomaterial risk assessments. The complex properties of various nanomaterials make evaluating them in the abstract or with generalizations difficult if not impossible. Thus, this document focuses on two specific uses of nano-TiO2, as a drinking water treatment and as topical sunscreen. These case studies do not represent completed or even preliminary assessments; rather, they present the structure for identifying and prioritizing research needed to support future assessments.

    Green roof construction in the United States is growing at a rate of 60 to 80 per cent per year. This paper presented two case studies of green roof construction in Minnesota. In both cases, construction and budgeting delays moved the installation of the green roofs from early-May to mid-July. The first case study was a 20,000 square foot extensive green roof on the new Minneapolis Central Library which was completed in 2005. The second case study was a 30,000 square foot extensive green roof on the Mdewakanton Sioux Waste Water Treatment Plant in Shakopee, which was completed in 2006. This paper demonstrated that in order for green roofs to serve the functions for which they were intended, clear guidelines and specifications are needed to ensure that they are healthy. The size and locations of the two roofs were quite different, but they were identical in terms of waterproofing. State-of-the-art inverted hot-applied roof membrane technology was used in both roofs along with sub-surface irrigation systems. A mycorrhizae fungi was used in both cases to amend the growing medium. Both roofs used a diverse pallet of native and traditional sedum plant material. This paper highlighted preventative measures taken to ensure the successful installation and establishment of the two roofs built during extreme heat and drought-like conditions. The positive results confirm that it is possible to install green roofs during extremely harsh summer conditions. 9 refs., 4 tabs., 3 figs.

    2012-01-01

    The case of " entry slop barge unloading" highlights the predicaments in applying international environmental treaties to domestic environmental administrative law: the contradiction between international treaties and domestic law, the difficulties in introducing international treaties to the domestic context, and the risks of deviating from original target and principle of international treaties. Such predicament may stern from the charac- teristics of environmental problems including globalization, sovereignty and localization. Therefore, when apply- ing international treaties to the enforcement of domestic environmental administrative law, to guarantee due effect, we need to stick to the principles, make appropriate interpretation and complement necessary approaches. In addition, we somehow need to transform the basis for enforcement, adjust the means of implementation, coordinate domestic mechanism according to the international treaties, and ultimately achieve a positive interaction between the two aspects.%“入境卸驳污油水案”突出显现了国内环境行政执法适用国际环境条约的困境:国际环境条约与国内环境法之间发生抵触,国际环境条约在国内实施时存在障碍以及可能面临偏离国际环境条约制定目标的风险等。究其成因盖源于环境问题的全球性、主权性和地方性等特点。因此,既要在国内环境行政执法中通过严格适用、恰当解释以及原则补充等方法影响国际环境条约的国内实施效果,也要通过转化执法依据、明确操作办法、协调国内机制等方法因应国际环境条约对国内环境行政执法的要求,最终通过两个方面的良性互动促成国内环境行政执法对国际环境条约的善意履行。

    The purpose of this study is to reveal the different risk factors related to this cancer particularly that there is no agreement about which factors affect the risk. A fishing expedition hospital based case control study was carried out. Cases and controls were identified from the Urology Department of Alexandria Main University Hospital, 2004. All cases diagnosed as having the tumor were included in the case series. For each case the second subject proved to have a negative pathological examination was included in the control group (50).Data collection was carried out blindly using a structured interview schedule. Analysis was applied using Chi-square test, Fisher exact and Student's t-test. Odds Ratios and 95% Confidence Intervals were calculated. Results indicated that regular consumption of sausages was greater among cases than controls (X(2)= 10.19, p= 0.001 and an odds ratio of 5.92 (CI: 1.69-25.99). Also more cases claimed consuming regularly butter and natural ghee than controls (X(2)= 5.47, p= 0.019). The estimate risk was as high as 2.79 (Cl: 1.07-7.33). However regular consumption of vegetables was more encountered among controls than cases (X(2) = 5.005, p= 0.025 where the odds ratio was 0.19 (Cl: 0.02-1.01). Moreover the multiple regression analysis confirmed the results obtained from univariate analysis. The consistency of results of current work as regards sausages and butter with several other research works can support the identification of these specific possible risk factors. Also other research workers pointed out to the protective effect of vegetables. However further research is needed to address other risk factors.

    AIM: Dieulafoy's lesion (DL) accounts for 1-5.8% of cases of acute upper gastrointestinal bleeding (GIB). Its mortality is high, approaching 20%, despite recent advances in endoscopic therapy. We aimed to report our experience in the treatment of DL.METHODS: A retrospective case study of all patients with DL between January 1993 and January 2003 was done. Characteristics, treatment methods, success rates and 30-d mortality of the patients were analyzed. RESULTS: Thirty-six patients were noted to have DL in the study period. Thirty-three records were available for assessment in which 35 DL were identified. The median age of the patients was 67 years with male to female ratio of 5.6:1. Significant comorbidities existed in 69% of the patients. Eighty-nine percent of the DL was found at first endoscopy, three DL at laparotomy. Significant coexistent endoscopic findings existed in 23%. Hemostasis was achieved in 88% by using adrenaline injection, or in combination with heater probe application at first endoscopy. Four cases had re-bleeding, all were successfully treated endoscopically. The 30-d mortality rate was 23%.CONCLUSION: Successful endoscopic hemostasis could be achieved in 100% of cases of DL. The overall mortality may still remain high, mainly due to the comorbidities and age of these patients.

    Simultaneous detection of several VNTR loci using a single DNA probe is the basis of the technique called "DNA fingerprint" (DNAfp) of increasing application in parenthood identification. According to the data gathered by different laboratories worldwide, father exclusion can be made in a larger number of cases when compared with the customary tests based on erythrocyte antigens. The question could then be whether DNAfp will completely replace erythrocyte antigens tests. We report here our experience in applying DNAfp to 92 samples corresponding to 34 paternity cases and comparing these with the results obtained with the antigens of the systems ABO, Rh, MNSs, Duffy and Kidd. Most of the HaeIII/digested DNA samples produced 13 to 16 bands larger than 4.3 Kb (average 14,0761 +/- 2,205). Average band sharing between pairs of unrelated individual was 1,9107 +/- 1,083. Two cases presenting an a posteriori probability of being the father of 80.7% and 76.5% by erythrocyte antigens were clearly excluded by DNAfp. All exclusions made by antigens were confirmed by DNAfp. In the cases reported as father "rather probable" (28 cases) by DNAfp, these shared with the child 6,7407 +/- 1.7 bands on average. Because of time, cost and simplicity we favor a procedure starting with the antigens test and continuing with DNAfp only when an exclusion is not possible. Economy will increase as the number of exclusions increases.

    2007-01-01

    Integrative Case-Based Applied Pathology (ICAP) cases form one component of learning and understanding the role of pathology in the veterinary diagnostic process at the Faculty of Veterinary Science, University of Sydney. It is a strategy that focuses on student-centered learning in a problem-solving context in the year 3 curriculum. Learning exercises use real case material and are primarily delivered online, providing flexibility for students with differing learning needs, who are supported by online, peer, and tutor support. The strategy relies heavily on the integration of pre-clinical and para-clinical information with the introduction of clinical material for the purposes of a logical three-level, problem-oriented approach to the diagnosis of disease. The focus is on logical diagnostic problem solving, primarily using gross pathology and histopathological material, with the inclusion of microbiological, parasitological, and clinical pathological data. The ICAP approach is linked to and congruent with the problem-oriented approach adopted in veterinary medicine and the case-based format used by one of the authors (PJC) for the teaching and learning of veterinary clinical pathology in year 4. Additionally, final-year students have the opportunity, during a diagnostic pathology rotation, to assist in the development and refinement of further ICAPs, which reinforces the importance of pathology in the veterinary diagnostic process. Evidence of the impact of the ICAP approach, based primarily on student surveys and staff peer feedback collected over five years, shows that discipline-specific learning, vertical and horizontal integration, alignment of learning outcomes and assessment, and both veterinary and generic graduate attributes were enhanced. Areas for improvement were identified in the approach, most specifically related to assistance in the development of generic teamwork skills.

    2016-04-18

    Shape is an inherent trait of a molecule that dictates how it interacts with other molecules, either in binding events or intermolecular reactions. Large-ring macrocyclic compounds in particular leverage their shape when they are selectively bound by biomolecules and also when they exhibit macrocyclic diastereoselectivity. Nonetheless, rules that link structural parameters to the conformation of a macrocycle are still rudimentary. Here we use a structural investigation of a family of [13]-macrodilactones as a case study to develop rules that can be applied generally to macrocycles of different sizes and with a variety of functionality. A characteristic "ribbon" shape is adopted by the [13]-macrodilactones in the absence of stereogenic centres, which exhibits planar chirality. When one stereogenic centre at key positions on the backbone is incorporated into the structure, the planar chirality is dictated by the configuration of the centre. In cases where two stereogenic centres are present, their relationships can either reinforce the characteristic ribbon shape or induce alternative shapes to be adopted. The rules established in the case study are then applied to the analysis of a structure of the natural product migrastatin. They lay the groundwork for the development of models to understand macrocycle-biomolecule interactions and for the preparation of macrocycles with designed properties and activities.

    The objective of this work was to study the effect of magnetic fields on the rate of phenol biodegradation using immobilized activated sludge. A recirculation flow bioreactor employing immobilized bacterial beads was used with phenol as the substrate to study the biodegradation process. This study was conducted by applying separately the north pole and the south pole magnetic fields to the bioreactor. Rate of dissolved oxygen consumption, phenol concentration and extracellular protein concentration were the parameters monitored during the process. It was observed that by applying a magnetic south pole to the process, biodegradation in the form of biological oxidation was enhanced. A 30% increase in biodegradation rate was obtained by applying a magnetic south pole of strength of 0.45 Tesla to the bioreactor with immobilized microbial beads as compared to the control. Magnetic north pole irradiation inhibited this type of biooxidation. This process has potential for biological treatment of organic wastes.

    Full Text Available This article is a qualitative case study describing the experience of Angélica an international graduate student from Latin America, who received her doctorate at the University of New Mexico in the United States. Her case demonstrated how administrators and faculty learn about the experience and struggles endured by international students, especially those who learned English a short time before admission to graduate studies. While a single case is understandably idiographic in nature and inevitably requires a larger sample, from the analysis of Angélica’s case and the analysis of the relevant literature common topics emerged persuading me to conclude that the issues that commonly impact the life of international students have to do with: 1 second language problems; 2 the quality of academic advisement received; 3 the availability of financial support; 4 the level of integration into their academic program; and 5 the level of cultural adjustment in their host country.

    A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

    2001-01-01

    The Global Hydrology and Climate Center and NASA's Marshall Space Flight Center conducted a fact-finding case study for the Data Management Working Group (DMWG), now referred to as the Data and Information Working Group (DIWG), of the U.S. Global Change Research Program (USGCRP) to determine the feasibility of an interagency National Environmental Change Information System (NECIS). In order to better understand the data and information needs of policy and decision makers at the national, state, and local level, the DIWG asked the case study team to choose a regional water resources issue in the southeastern United States that had an impact on a diverse group of stakeholders. The southeastern United States was also of interest because the region experiences interannual climatic variations and impacts due to El Nino and La Nina. Jointly, with input from the DIWG, a focus on future water resources planning in the Apalachicola-Chattahoochee-Flint (ACF) River basins of Alabama, Georgia, and Florida was selected. A tristate compact and water allocation formula is currently being negotiated between the states and U.S. Army Corps of Engineers (COE) that will affect the availability of water among competing uses within the ACF River basin. All major reservoirs on the ACF are federally owned and operated by the U.S. Army COE. A similar two-state negotiation is ongoing that addresses the water allocations in the adjacent Alabama-Coosa-Tallapoosa (ACT) River basin, which extends from northwest Georgia to Mobile Bay. The ACF and ACT basins are the subject of a comprehensive river basin study involving many stakeholders. The key objectives of this case study were to identify specific data and information needs of key stakeholders in the ACF region, determine what capabilities are needed to provide the most practical response to these user requests, and to identify any limitations in the use of federal data and information. The NECIS case study followed the terms of reference

    1999-12-14

    Isosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published leaving the user in a quandary about which one should be used. Some papers have published complexity analysis of the techniques yet empirical evidence comparing different methods is lacking. This case study presents a comparative study of several representative isosurface extraction algorithms. It reports and analyzes empirical measurements of execution times and memory behavior for each algorithm. The results show that asymptotically optimal techniques may not be the best choice when implemented on modern computer architectures.

  1. Nanomaterial Case Studies: Nanoscale Titanium Dioxide in ...

    Science.gov (United States)

    EPA announced the availability of the final report, Nanomaterial Case Studies: Nanoscale Titanium Dioxide in Water Treatment and in Topical Sunscreen. This report is a starting point to determine what is known and what needs to be known about selected nanomaterials as part of a process to identify and prioritize research to inform future assessments of the potential ecological and health implications of these materials. Two specific applications of nanoscale titanium dioxide (nano-TiO2) are considered: (1) as an agent for removing arsenic from drinking water; and (2) as an active ingredient in topical sunscreen. These case studies are organized around a comprehensive environmental assessment (CEA) framework that combines a product life cycle perspective with the risk assessment paradigm. They are intended to help identify what may need to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. These “case studies” do not represent completed or even preliminary assessments, nor are they intended to serve as a basis for risk management decisions in the near term on these specific uses of nano TiO2. Rather, the intent is to use this document in developing the scientific and technical information needed for future assessment efforts.

    2015-03-01

    Applied creativity involves bringing innovation to real-life activities. The first reared-apart twin study assessing genetic and environmental origins of applied creativity, via Draw-a-House (DAH) and Draw-a-Person (DAP) tasks, is presented. Participants included 69 MZA and 53 DZA twin pairs from the Minnesota Study of Twins Reared Apart. Drawings were evaluated by four artists and four non-artists. Genetic effects were demonstrated for the DAP (.38-.47), but not for the DAH. Creative personality showed genetic effects (.50), and modest, but significant correlations with scores on the two drawings (rs = .17-.26). Both genetic and nonshared environmental influences underlie variance in applied creativity. Individuals concerned with enhancing creativity among students and others may better understand individual differences in performance and training.

    Terahertz (THz) spectroscopy and imaging is a non-destructive, non-contact, non-invasive technology emerging as a tool for the analysis of cultural heritage. THz Time Domain Spectroscopy (TDS) techniques have the ability to retrieve information from different layers within a stratified sample, that enable the identification of hidden sub-layers in the case of paints and mural paintings. In this paper, we present the THz TDS2 system developed in the European Commission's 7th Framework Program project CHARISMA [grant agreement no. 228330]. Bespoke single processing algorithms; including a deconvolution algorithm can be deployed to increase the resolution and the global performance of the system. The potential and impact of this work is demonstrated through two case studies of mural paintings, where the capability to reveal the stratigraphy of the artworks is demonstrated.

  5. Practical guidance for the use of a pattern-matching technique in case-study research: a case presentation.

    Almutairi, Adel F; Gardner, Glenn E; McCarthy, Alexandra

    2014-06-01

    This paper reports on a study that demonstrates how to apply pattern matching as an analytical method in case-study research. Case-study design is appropriate for the investigation of highly-contextualized phenomena that occur within the social world. Case-study design is considered a pragmatic approach that permits employment of multiple methods and data sources in order to attain a rich understanding of the phenomenon under investigation. The findings from such multiple methods can be reconciled in case-study analysis, specifically through a pattern-matching technique. Although this technique is theoretically explained in the literature, there is scant guidance on how to apply the method practically when analyzing data. This paper demonstrates the steps taken during pattern matching in a completed case-study project that investigated the influence of cultural diversity in a multicultural nursing workforce on the quality and safety of patient care. The example highlighted in this paper contributes to the practical understanding of the pattern-matching process, and can also make a substantial contribution to case-study methods.

  10. Forecast Master Program case studies: Final report

    Energy Technology Data Exchange (ETDEWEB)

    Engle, R.; Granger, C.; Ramanathan, R. (ed.)

    1987-04-01

    This report presents a number of case studies using the computer software package FORECAST MASTER (FM). The series studied and forecast are, aggregate monthly California Electricity Sales, system energy demand data from Ontario Hydro, peak demand data for the residential and commercial customers of Georgia Power Company, Massachusetts Electric commercial sales, Narragansett Electric commercial sales, average and peak demand using Georgia Power Company data. A variety of methods have been studied by each of the contributing authors; trend line fitting, exponential smoothing, Box-Jenkins univariate forecasting, vector autoregression, state space modeling, dynamic econometric models including time-varying parameters and general order serial correlation corrections. Thus both the data sets and the modeling/forecasting methodologies are varied. A number of conclusions emerge from these case studies: FM provides a powerful set of tools to aid a utility forecaster, a great deal of caution should be exercised in pre-processing the data; it can have unintended side effects, diagnostic tests are very useful in econometric models, the Akaike Information Criterion is a useful measure for selecting the best state space model, and state space and econometric approaches both need equal amounts of care in model analysis and presentation.

  11. Linking biomedical engineering ethics case study approach and policy.

    Science.gov (United States)

    Dibrell, William; Dobie, Elizabeth Ann

    2007-01-01

    In this paper we link bioengineering case study methods to the development of policy. The case study approach to ethics is an excellent way to show the complex nature of practical/moral reasoning. This approach can, however, lead to a kind of overwhelming complexity. The individual nature of each case makes it difficult to identify the most important information and difficult to see what moral considerations are most relevant. In order to make the overwhelming complexity less debilitating, we present a framework for moral decision making derived from suggestions made by W.D. Ross and Virginia Held. Ross articulates the multiple sources of morality and Held deepens the discussion by reminding us of the foundational importance of care and sympathy to our moral natures. We show how to use the notion of prima facie duty and discuss moral conflict. In doing this, we show how the framework, applied to cases, can be of assistance in helping us develop policies and codes of ethics with sufficient plasticity to be useful in the complex world of the bioengineer.

    Bailey, Janelle M.; Nagamine, Kentaro

    2012-06-01

    Understanding faculty motivations for and barriers to change is an important component of facilitating instructional reform efforts to improve student learning. This case study describes the process of adoption of learner-centered instructional strategies by an astronomy faculty member, Ken, as viewed through the lens of conceptual change. Specifically, we applied the Cognitive Reconstruction of Knowledge Model (CRKM) to understand why Ken was willing to change his instructional strategies, what barriers to and supports for change existed, and how he and his students were impacted by this change. Ken's statements and actions represented characteristics consistent with the CRKM. Notably, dissatisfaction, considered the primary motivator in many conceptual change models, was not of high importance in this case. Upon implementing learner-centered strategies, Ken's students performed better on a measure of knowledge about stellar properties, which served to reinforce his motivation to continue with learner-centered methods.

    Full Text Available We revisit the AMBA AHB case study that has been used as a benchmark for several reactive synthesis tools. Synthesizing AMBA AHB implementations that can serve a large number of masters is still a difficult problem. We demonstrate how to use parameterized synthesis in token rings to obtain an implementation for a component that serves a single master, and can be arranged in a ring of arbitrarily many components. We describe new tricks - property decompositional synthesis, and direct encoding of simple GR(1 - that together with previously described optimizations allowed us to synthesize a component model with 14 states in about 1 hour.

    Metrology is recognized by improving production process, increasing the productivity, giving more reliability to the measurements and consequently, it impacts in the economy of a country. Pharmaceutical area developed GMP (Good Manufacture Practice) requeriments, with no introduction of metrological concepts. However, due to Nanomedicines, it is expected this approach and the consequent positive results. The aim of this work is to verify the level of metrology implementation in a Brazilian pharmaceutical industry, using a case study. The purpose is a better mutual comprehension by both areas, acting together and governmental support to robustness of Brazilian pharmaceutical area.

    2009-12-01

    Full Text Available Abstract Background The quantification of uncertainty and variability is a key component of quantitative risk analysis. Recent advances in Bayesian statistics make it ideal for integrating multiple sources of information, of different types and quality, and providing a realistic estimate of the combined uncertainty in the final risk estimates. Methods We present two case studies related to foodborne microbial risks. In the first, we combine models to describe the sequence of events resulting in illness from consumption of milk contaminated with VTEC O157. We used Monte Carlo simulation to propagate uncertainty in some of the inputs to computer models describing the farm and pasteurisation process. Resulting simulated contamination levels were then assigned to consumption events from a dietary survey. Finally we accounted for uncertainty in the dose-response relationship and uncertainty due to limited incidence data to derive uncertainty about yearly incidences of illness in young children. Options for altering the risk were considered by running the model with different hypothetical policy-driven exposure scenarios. In the second case study we illustrate an efficient Bayesian sensitivity analysis for identifying the most important parameters of a complex computer code that simulated VTEC O157 prevalence within a managed dairy herd. This was carried out in 2 stages, first to screen out the unimportant inputs, then to perform a more detailed analysis on the remaining inputs. The method works by building a Bayesian statistical approximation to the computer code using a number of known code input/output pairs (training runs. Results We estimated that the expected total number of children aged 1.5-4.5 who become ill due to VTEC O157 in milk is 8.6 per year, with 95% uncertainty interval (0,11.5. The most extreme policy we considered was banning on-farm pasteurisation of milk, which reduced the estimate to 6.4 with 95% interval (0,11. In the second

Medical literature is sparse detailing the manifestations and management of such symptoms. In myonecrosis, red cells containing sickle hemoglobin become rigid, resulting in reduced blood flow and myonecrosis. Case Report: We present a case study of a patient in sickle cell crisis with an episode of acute pain and swelling to the intrinsic muscles of the foot as a prominent feature of the crises. Although muscle biopsy is considered the gold standard for the diagnosis of myositis or myonecrosis, a low intensity signal on T1 and high intensity signal on T2 at the affected muscle belly can be as conclusive as imaging studies. In an actively sickling patient any invasive intervention should be avoided as it can result in ischemic necrosis of the tissues, due to interruption of capillary flow in end-arteries. Conclusions: Early recognition is critical in sickle cell disease management, allowing for prompt and aggressive fluid resuscitation which remains a cornerstone in the management of most sickle cell vaso-occlusive crises. In this instance, off loading the extremity and early fluid resuscitation resolved the pain and swelling and prevented myonecrosis. PMID:28133359

These examinations are delivered in partnership with a commercial online testing company as part of the Industry Master’s degree at Charles Sturt University (CSU. The Industry Master’s degree is an academic program for students currently employed in the IT industry. Using Internet Based Testing (IBT, these students are examined in test centres throughout the world. This offers many benefits. For example, students have the freedom of sitting exams at any time during a designated interval. Computer-based testing also provides instructors with valuable feedback through test statistics and student comments. In this paper, we document CSU’s use of the IBT system, including how tests are built and delivered, and how both human and statistical feedback is used to evaluate and enhance the testing process.

    2011-01-01

    Pain is a widespread issue in the United States. Nine of 10 Americans regularly suffer from pain, and nearly every person will experience low back pain at one point in their lives. Undertreated or unrelieved pain costs more than $60 billion a year from decreased productivity, lost income, and medical expenses. The ability to diagnose and provide appropriate medical treatment is imperative. This case study examines a 23-year-old Active Duty woman who is preparing to be involuntarily released from military duty for an easily correctable medical condition. She has complained of chronic low back pain that radiates into her hip and down her leg since experiencing a work-related injury. She has been seen by numerous providers for the previous 11 months before being referred to the chronic pain clinic. Upon the first appointment to the chronic pain clinic, she has been diagnosed with sacroiliac joint dysfunction. This case study will demonstrate the importance of a quality lower back pain assessment.

    California is the largest cement producing state in theU.S., accounting for between 10 percent and 15 percent of U.S. cementproduction and cement industry employment. The cement industry inCalifornia consists of 31 sites that consume large amounts of energy,annually: 1,600 GWh of electricity, 22 million therms of natural gas, 2.3million tons of coal, 0.25 tons of coke, and smaller amounts of wastematerials, including tires. The case study summarized in this paperfocused on providing background information, an assessment ofenergy-efficiency opportunities and barriers, and program recommendationsthat can be used by program planners to better target products to thecement industry. The primary approach to this case study involvedwalk-through surveys of customer facilities and in depth interviews withcustomer decision makers and subsequent analysis of collected data. Inaddition, a basic review of the cement production process was developed,and summary cement industry energy and economic data were collected, andanalyzed. The analysis of secondary data provides background informationon the cement industry and identification of potential energy-efficiencyopportunities. The interviews provide some understanding of the customerperspective about implementation of energy-efficiencyprojects.

    Most college biochemistry courses are taught in a format in which the professor lectures and the student memorizes. Although this is the best method for conveying large amounts of material, it puts the student in the position of passive learner. The lecture-based format has not been abandoned, but has been supplemented with case study projects assigned to the students upon completion of the intermediary metabolism unit. The case study assignment is modeled on similar exercises carried out in medical school biochemistry courses in the US and around the world. A description of the assignment follows: a group of 4-5 students is given a case study which gives the medical history of a patient with an inherited metabolic disease. The group is asked to provide biochemical explanations for the patient's symptoms and to suggest an effective course of treatment. The evaluation consists of a short paper that the students write as a group. The assignment provides the opportunity for small group interaction within a larger class and emphasizes cooperative-collaborative learning. Students learn by researching the topic on their own and debating it in small group discussions, and in so doing, gain a sense of confidence in themselves and the material they have learned over the course of the semester. Solving a "real-life" problem helps develop analytical and higher-order thinking skills and allows the students to see how biochemical concepts they have learned apply to a clinical situation.

    2012-12-01

    Full Text Available A broad scientific consensus exists that the global climate is changing. The Earth’s surface temperature could rise significantly over the next few decades, leading to us witnessing an entirely new and unknown planet. Improved energy efficiency, decreasing use of fossil fuels and wide diffusion of various renewable energy sources are among the focal measures to limit global warming to a sustainable level. The objective of this study is to analyse how renewable energy, such as wind power and bioenergy, could be efficiently commercialized. The evaluation is based on a case study and expert analyses exploiting lateral and parallel thinking methods, and group decision support systems tools. The results reveal that some of the generated ideas are ready for implementation to commercialize renewable energy, whereas others still require technical and commercial development and improvements before maturity.

    Full Text Available Emergency management agencies are progressively using social media for the sourcing and distribution of disaster information. Emergency management agencies are often unsure as to how to best identify and assess social media concerns (e.g. information security, trust which must be addressed to develop a social media-enabled disaster information management environment. This paper adopts the Social Architecture Viewpoint Assessment (SAVA framework for identifying and assessing social media concerns from four different viewpoints: IT, Value, Resource and Management. This paper demonstrates the use of the SAVA framework in the context of an in-depth empirical case study of an Australian emergency management agency. The results of this study indicate that the SAVA framework is useful for emergency information management managers in identifying and assessing social media concerns.

    1998-12-31

    A brief account of various causes of climate change in recent decades and climate change trends in the Indian region is presented. Local temperature is one of the major climatic elements to record the changes in the atmospheric environment caused by industrialization and urbanization. Literature data show that there is either a cooling tendency or cessation of warming after the late 1950s at most of the Indian industrial cities. A case study of Nagpur, a centrally located city in India, is done to understand the possible causes of cooling. Nagpur is the only city in India for which a long-term record of temperature, for urban (Mayo Hospital) and relatively suburban (Sonegaon Airport) area, is available. The study of the diurnal asymmetry in maximum and minimum temperatures indicates that the role of suspended particulate matter dominates over that of increasing greenhouse gases.

    Levin, R; Daly, R S

    1998-01-01

    There have been numerous reports in the literature on the descriptive similarities between a severe nightmare and an acute psychotic episode. Nightmares may be a prelude to psychotic decompensation, and it has been suggested that frequent lifelong nightmares may even be diagnostic of an underlying vulnerability to psychosis. In this report, we present a case study of a 40-year old female experiencing chronic paranoid schizophrenia, whose two witnessed psychotic relapses in the hospital were immediately preceded by intense and vivid nightmare attacks. Significantly, the content of these nocturnal dreams was thematically consistent with her waking hallucinations, suggesting a direct continuity between these experiences. We propose that further systematic study of the dreams and nightmares of individuals diagnosed with schizophrenia may be particularly useful in understanding their phenomenological experience.

    The scheduling in job shop is important for efficient utilization of machines in the manufacturing industry. There are number of algorithms available for scheduling of jobs which depend on machines tools, indirect consumables and jobs which are to be processed. In this paper a case study is presented for scheduling of jobs when parts are treated on available machines. Through time and motion study setup time and operation time are measured as total processing time for variety of products having different manufacturing processes. Based on due dates different level of priority are assigned to the jobs and the jobs are scheduled on the basis of priority. In view of the measured processing time, the times for processing of some new jobs are estimated and for efficient utilization of the machines available an algorithm is proposed and validated.

    Full Text Available This is a research into the assessment of tourism industry quality and programing for its development in Iran. In a tough economic situation, the hypothesis is to grow and develop the national economy with the help of the tourism industry. A unified assessment of tourism industry quality, method is made use of in this study, which is based on the case study of all elements of Iran tourism industry system. Quality assessment by means of unified problems (indicators that hinder the maximum development of the tourism industry shows the reliability of the hypothesis. SWOT analysis aided to determine the weaknesses and threats aiming at raising the quality of the indicators. In addition, a linear programming from the standpoint of internal and external relations with national economy has been applied. The analysis revealed that the system of the tourism industry is unable to assist the macro economy. The failure corresponds to scarcely favorable natural environmental conditions, capacity for motivating to visitors, tourism marketing, and tourism infrastructures. After remedy actions, prospects for tourism industry development despite the complicated situation are quite favorable due to the advantageous climate, natural characteristics, cultural and ancient heritages, tourism resources, and educated labor. The methods applied by this paper suggest adaptive governance tools suitable to apply for optimization of the tourism industry everywhere similar to Iran.

    Platelet gel biotechnology, a method which has all the components of "tissue engineering" techniques, potentiates the already known healing process of guided tissue regeneration procedures (GTR) by multiplying the number of molecules that activate the healing response and by grafting in the host site various cell types, among which stem cells. Here are reported cases of patients affected by refractory generalized aggressive periodontitis treated with the association GTR and platelet gel biotechnology to verify if the contribution of the gel would produce superior results than those obtained by surgery alone which had been previously applied to the same sites with negative results. Three patients in therapy from 4 to 11 years, already subjected to surgery (GTR) and antibiotic therapy, were reoperated with the adjunct of autologous platelet gel. At a distance of 15.2 months (range 11-17 months) the operated sites showed a reduction in probing pocket depth of 3.4 mm (range 2.8-4.8 mm) and a gain in clinical attachment level of 3.1 mm (range 3-3.5 mm). The association of platelet gel biotechnology with GTR in the surgical treatment of intrabony defects of refractory generalized aggressive periodontitis patients seems to produce results similar to those reported for patients with chronic adult periodontitis. The observations at 15.2 months indicate that there is a stability over time of the results in those sites where previous surgical therapy had shown relapse.

    Full Text Available Means of accommodation involve a wide range of social actors and agents, as well as different business models. Management strategies in this sector have been increasingly important for long-term sustainability and competitiveness of business organizations. This study aims to analyze the interactions between apart-hotels and their stakeholders to foster an improvement of services provided, aligning the interface of strategic management from the point of view of managers and their key stakeholders. It is an exploratory study, with qualitative chacter, along with multiple case studies of the following establishments: Travel Inn, Hotels Slaviero and Etoile george v. Brazilian enterprises, which manage lodging facilities with apart-hotel concepts, combining features that enable comparative analysis of the study. For conceptual understanding, this study was based on literature about stakeholders, taking the work of Freeman (1984 and Freeman et al (2010 as main references. The research was conducted through semi-structured interviews with managers of lodging facilities and their key stakeholders and through direct observation and documentation. We found that not all groups of influence are considered in the planning of service flats. However, the organizations surveyed indicated that the market has realized the importance of the groups that exert influence and are influenced by their goals, and are therefore increasingly alert for integration of such groups in their strategic planning.

    2015-04-01

    According to Erik Erikson's theory on the stages of human development, achieving wisdom later in life involves revisiting previous crises and renewing psychosocial accomplishments. However, few studies have used Erikson's theory as a framework for examining how older adults self-manage physical and mental health changes that commonly occur later in life. This article presents findings from two qualitative studies that demonstrate how older adults apply wisdom in new domains. Specifically, it was found that older adults (1) reasserted autonomy by initiating creative problem solving and (2) applied skills gained from productive activities earlier in life to new health-related problems that arise later in life. These findings highlight the importance of engaging older adults to repurpose their life skills and thus reapply wisdom to new areas of their lives. Implications for practice are discussed.

    Fixture is an important manufacturing activity. A fixture design system based on case-based reasoning (CBR) is proposed in this paper. A new method of case representation on the basis of fixture function is presented, where the case representation is constituted of workpiece knowledge, processing feature knowledge, and fixture feature knowledge. Running the prototype system shows that the knowledge representation method, using cases, is a better way to transform and explain the design knowledge.

    Full Text Available This study highlighted the importance of determining the impact that an ineffective mode of transport has on a firm’s transportation model and costs. The main focus of this study was to determine the logistics opportunity costs of using road transport within a mining firm. A case study approach was followed, as the investigation aimed to analyse a complex problem experienced by one company and present it in an easily understandable format. From the results of this study, it was apparent that the logistics opportunity costs associated with the mode of transport was substantial. This highlighted the need for firms to revise their choice of transport mode on a regular basis, as it has a major impact not only on their transportation costs, but also on their inventory holding and carbon emissions. The results also have implications for South Africa’s only freight railway, Transnet Freight Rail, which should not only focus on expanding its existing capacity, but also on improving its customer service delivery whilst containing tariff increases.

    2014-02-01

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    Woods, Christopher W; Woods, Amanda G; Cederholm, Carmen K

    2013-12-01

    Vitamin K deficiency bleeding (VKDB), formerly known as hemorrhagic disease of the newborn (HDN), is a bleeding disorder in neonates that is caused by inadequate serum levels of vitamin K. Vitamin K is a nutrient essential for adequate function of the coagulation cascade. Certain internal and external factors place newborn infants at higher risk for VKDB. Therefore, vitamin K prophylaxis has become the standard of care for newborns. Although the American Academy of Pediatrics recommends the administration of vitamin K to newborns, some parents are choosing to withhold vitamin K administration at birth. This case study describes an infant who developed VKDB in the absence of vitamin K prophylaxis. Although parents ultimately have the right to choose whether or not to administer vitamin K, as healthcare professionals, it is important to provide education regarding the potential complications of withholding vitamin K and the signs of VKDB if vitamin K prophylaxis at birth is withheld.

    Full Text Available In todays economics, the fact that information is a major factor of production and of increasing importance as a source of competitive advantage is a generally accepted truism. The trend towards global markets has strongly impacted the competitive situation of many enterprises. Never has the economic environment been subject to so many drastic and rapid changes. This put new weight factors on the requirements for design of business process. This paper explores the case of an Italian legal office that has studied more and more innovative solutions both to satisfy the demands of the clienteles and to oppose the action of the new competitors. Comparing classic models and the theories of Porter with the characteristics and needs of new economy, it shows as the ability to possess, to easily have access, to creatively use of information constitutes one of the more strategic sources of the competitive advantage.

    1983-01-01

    Seventeen cases of late ulnar paralysis treated by neurolysis-transposition are reported. The clinical characteristics of these paralysis are emphasized. A very prolonged symptom free interval, a rapid onset and a severe involvement. The ulnar transposition was most often done subcutaneously. Cubitus valgus and definite nerve compression proximal to the arcade of the flexor carpi ulnaris muscle are almost always present. The results as regards the neuropathy are notable: no patient is completely cured and only half are improved. An anatomical study of the nerve path shows the essential role, in the compression of the nerve, of the muscular arcade of the flexor carpi ulnaris muscle which acts in a way similar to the bridge of a violin. Hence, opening it longitudinally is the principal procedure of the neurolysis. This should be routine before the first signs of neuropathy occur in an elbow whose axis is out of alignment as a sequela of a childhood injury.

    2016-01-01

    The present study aims to evaluate national adaptation planning, using the National Action Plan for Climate Change Adaptation (RAN-API) in Indonesia as a case. In doing so, the current study applies the methodology used in Preston et al. (2011), where a set of 57 adaptation plans from three developed countries was evaluated against 19 planning processes. The same criteria and scoring system were applied to the current study to evaluate RAN-API, both as identified in its document and as viewed by the stakeholders. A desktop review and questionnaires were undertaken to this end. It was found that discrepancies exist between the status of RAN-API as documented and the stakeholders views of some criteria, suggesting that information or knowledge gaps may still exist despite the efforts made for stakeholder engagement. In some of the other criteria, the stakeholders views match the status as identified in the document. Most notably, they both agree that the weakness of RAN-API is related to limited consideration for non-climatic factors. While the development of RAN-API is a critical step taken in the country, the current study finds that there remains room for further improvement. The criteria or indicators to be used to assess the progress of RAN-API as a whole may need to be further elaborated.

  9. Evaluating EML Modeling Tools for Insurance Purposes: A Case Study

    2010-01-01

    Full Text Available As with any situation that involves economical risk refineries may share their risk with insurers. The decision process generally includes modelling to determine to which extent the process area can be damaged. On the extreme end of modelling the so-called Estimated Maximum Loss (EML scenarios are found. These scenarios predict the maximum loss a particular installation can sustain. Unfortunately no standard model for this exists. Thus the insurers reach different results due to applying different models and different assumptions. Therefore, a study has been conducted on a case in a Swedish refinery where several scenarios previously had been modelled by two different insurance brokers using two different softwares, ExTool and SLAM. This study reviews the concept of EML and analyses the used models to see which parameters are most uncertain. Also a third model, EFFECTS, was employed in an attempt to reach a conclusion with higher reliability.

    Purpose: To investigate how Risk Management (RM) is perceived and practiced in Facilities Management (FM) and corporate management and to evaluate the potential benefits of an increased application. Theory: RM is a generic management discipline, but apparently it has not achieved the attention...... it deserves in FM. Application of RM in FM could help to increase the strategic importance and awareness of FM among corporate managers. Approach: A preliminary study with expert interviews was initially conducted followed by a main study with an interview survey in two Danish case companies - a real estate...... company and a consulting engineering company. Findings: The research showed that RM was applied in both companies to a higher degree than initially expected, but often using other terminology. The real estate company had a much stronger focus on RM in relation to the technical aspects of real estate...

    Quartz and feldspar crystals were selected from the samples as eolic dunes, beach-rock and marine terraces, all collected in the coast area of Paraiba State, located in northeastern Brazil, in order to obtain ages of deposition of the sediments. It is a systematic study in the area. The results of the ages will be used in local sea-level changes study and a correlation between highstands of marine oxygen-isotopes stages will be made. Optically stimulated luminescence and thermoluminescence have been measured and the regeneration method with multiple aliquot protocol was applied to obtain the paleodose values. Preliminaries ages spanning 3.2-229 kyr were evaluated.

    The study of planets around other stars has entered a science-rich era of characterization, in which detailed information about individual planets can be inferred from observations beyond mere detection, which only yields bulk properties like mass or radius. Characterization probes more revealing quantities such as chemical abundances, albedo, and temperature/pressure profiles, which allow us to address larger questions of planet formation mechanisms, planetary evolution, and, eventually, habitability and presence of biosignature gases. The primary method for characterization of close-in planets is transit spectroscopy. This dissertation talk will focus on transiting exoplanet case studies with the Hubble Space Telescope’ Wide-Field Camera-3 (WFC-3) as a tool of exoplanet characterization in a near-infrared band dominated by strong water features. I will first present a characterization the WFC-3 systematic effects that must be mitigated to extract the incredibly small (tens to 200 parts per million) signals, and then a study of four transiting giant planets (HATS-7b, HAT-p-3b, HD 149026b, and WASP-18b) in transmission, and two (WASP-18b and CoRoT-2b) in eclipse. Finally, I will discuss the role of transit timing monitoring of WASP-18b with HST and other observatories as another clue to its evolution as a close-in, massive planet. The five planets range from Neptune-class to Super-Jupiter-class in size/mass. Though these planets may be relatively rare, their observability represents a unique opportunity to probe planet formation and evolution, as well as atmospheric structures in a high-irradiation environment. These observations also yield insights into aerosols (i.e. clouds/hazes) in the atmosphere; clouds and/or hazes should significantly impact atmospheric chemistry and observational signatures, and we as a community must get a better handle on the phenomenon of aerosols in advance of the next generation of space observatories, including JWST and WFIRST

  14. Theory of stages applied to the studies of motor development: a revision

    Full Text Available Theory of stages applied to motor development was based on development psychology, proposed by Piaget. The idea was that the cognitive behavior was undergoing qualitative changes called stages. And it was that idea which provided the basis for building a theory of stages for motor behaviour. Since then, the goal of the professional who works with motor development has been to try to explain the process of acquisition of fundamental movements through a hierarchical sequence of stages, identified since the first movement manifestation until its execution in a mature way. This article, however, aims not at confirming the theory of stages as adequate, but at carrying out an explanation about such theory applied to the studies of motor development, considering its principal characteristics as well a discussion of such content in face of new trends.

    Although astronomy plays an important role in the most various outreach initiatives, as well as school science curricula, due to its strong visual component in knowledge acquisition, astronomy subjects are not entirely well addressed and accessed by visually impaired students and/or general public. This stresses the need of more tactile material production, still very scarce in an educational context whether formal or informal. This is a case study activity developed based on different schematic tactile images of several objects present in our solar system. These images in relief, highlight, through touch, several relevant features present in the different astronomical objects studied. The scientific knowledge is apprehended through the use of a tactile key, complemented with additional information. Through proper hands-on activities implementation and careful analysis of the outcome, the adapted images associated with an explanatory key prove to be a valuable resource in tactile astronomy domain. Here we describe the process of implementing such initiative near visually impaired students. The struggles and challenges perceived by all involved and the enrichment experience of engaging astronomy with visually impaired audiences, broadening horizons in an overall experience accessible to all.

    Full Text Available Eating disorders lead to special biological and psychological states. The result of the total lack of food is treated in a distinct way by anorexia. Nutritionists have thus had difficulty in coming to an agreement on the best therapy to prevent such disorders. First it is essential to understand which treatment aims are and then to attempt to know how the several treatment models used nowadays can reach those aims. Someone who suffers from eating disorders, together with an inner deformation, suffers from too much sensitiveness. In order to solve these problems, one needs a change in the relationship with oneself, with the others and with the world. This study presents a teenager’s case study – Anorexia. Is, in fact, a problem that society faces and can’t ignore. Many youngsters have already died and others are following their steps. But there are also those ones that succeeded in overcoming the problem and now are reporting their stories.

    The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

    Full text: A 55-year-old female presented to the Alfred Emergency Department semi-conscious with frank rectal bleeding requiring blood volume replacement. Labelled red blood cell (RBC) scintigraphy was requested in order to locate the site of bleeding. In vitro labelling of 3 mL of patient``s blood was performed (PYP as a diluted tinning agent and 1 GBq of freshly eluted {sup 99}mTc) and suspended red cells were injected. Using a GE Starcam system with high resolution collimation, images were acquired for 30 seconds (2 s per frame) and thereafter continuously for 1. 5 hours (30 s per frame). During imaging, patient history became available revealing portal hypertension, oesophageal and anal varices due to myelofibrosis and previous cholecystectomy. Initial flow images showed bizarre abdominal collateral vessels. Accumulation of labelled RBC over 1.5 hours in the right upper quadrant indicated the hepatic flexure as the site of bleeding. The initial flow study showing major porto-systemic collateral vessels indicated that therapeutic embolisation via angiography would be life threatening. The patient underwent emergency hemicolectomy and has been bleed-free to date. In this case, delayed RBC scintigraphy accurately located the haemorrhage site. However, the initial flow study demonstrating major vessel collateral flow was crucial in contraindicating angiographic embolisation. Surgery was then the only therapeutic option.

    Antineutrinos have been proposed as a means of reactor safeguards for more than 30 years and there has been impressive experimental progress in neutrino detection. In this paper we conduct, for the first time, a case study of the application of antineutrino safeguards to a real-world scenario - the North Korean nuclear crisis in 1994. We derive detection limits to a partial or full core discharge in 1989 based on actual IAEA safeguards access and find that two independent methods would have yielded positive evidence for a second core with very high confidence. To generalize our results, we provide detailed estimates for the sensitivity to the plutonium content of various types of reactors, including most types of plutonium production reactors, based on detailed reactor simulations. A key finding of this study is that a wide class of reactors with a thermal power of less than 0.1-1 GWth can be safeguarded achieving IAEA goals for quantitative sensitivity and timeliness with detectors right outside the reactor ...
