  1. Developing Collective Learning Extension for Rapidly Evolving Information System Courses (United States)

    Agarwal, Nitin; Ahmed, Faysal


    Due to rapidly evolving Information System (IS) technologies, instructors find themselves stuck in the constant game of catching up. On the same hand students find their skills obsolete almost as soon as they graduate. As part of IS curriculum and education, we need to emphasize more on teaching the students "how to learn" while keeping…

    Full Text Available Poul Jennum, Julie AE Christensen, Marielle Zoetmulder Department of Clinical Neurophysiology, Faculty of Health Sciences, Danish Center for Sleep Medicine, Rigshospitalet, University of Copenhagen, Copenhagen, Denmark Abstract: Rapid eye movement (REM sleep behavior disorder (RBD is a parasomnia characterized by a history of recurrent nocturnal dream enactment behavior and loss of skeletal muscle atonia and increased phasic muscle activity during REM sleep: REM sleep without atonia. RBD and associated comorbidities have recently been identified as one of the most specific and potentially sensitive risk factors for later development of any of the alpha-synucleinopathies: Parkinson’s disease, dementia with Lewy bodies, and other atypical parkinsonian syndromes. Several other sleep-related abnormalities have recently been identified in patients with RBD/Parkinson’s disease who experience abnormalities in sleep electroencephalographic frequencies, sleep–wake transitions, wake and sleep stability, occurrence and morphology of sleep spindles, and electrooculography measures. These findings suggest a gradual involvement of the brainstem and other structures, which is in line with the gradual involvement known in these disorders. We propose that these findings may help identify biomarkers of individuals at high risk of subsequent conversion to parkinsonism. Keywords: motor control, brain stem, hypothalamus, hypocretin

  3. Using INGRES as a rapid prototyping device during development of management information applications

    Energy Technology Data Exchange (ETDEWEB)

    Brice, L.; Connell, J.; Shafer, D.


    This paper presents case studies from the Administrative Data Processing Division of the Los Alamos National Laboratory where a prototyping too, the INGRES relational database system, has been used to develop management information systems. The tool has proved valuable in satisfying user requirements and expectations, and in aiding data processing in the analysis and specification phases of the system life cycle. The prototype approach helps enormously in bridging the developer-user communication gap and has been found to add a negligible amount of cost to the entire software development project. Presented here are four case studies of how INGRES has been employed in prototyping. Also presented are examples of specific INGRES features and how they were used in one of the case studies and further examples involving another similar case. Special considerations and cautions are required when using INGRES for prototyping, but the overall conclusion is that it is a tool which has tremendously benefited our organization. Whether the final implemented system is INGRES-based or not, prototyping greatly enhances the possibility of complete, correct and unambiguous specifications prior to final software product development.

  5. The impacts of climate change on poverty in 2030, and the potential from rapid, inclusive and climate-informed development (United States)

    Rozenberg, J.; Hallegatte, S.


    There is a consensus on the fact that poor people are more vulnerable to climate change than the rest of the population, but, until recently, few quantified estimates had been proposed and few frameworks existed to design policies for addressing the issue. In this paper, we analyze the impacts of climate change on poverty using micro-simulation approaches. We start from household surveys that describe the current distribution of income and occupations, we project these households into the future and we look at the impacts of climate change on people's income. To project households into the future, we explore a large range of assumptions on future demographic changes (including on education), technological changes, and socio-economic trends (including redistribution policies). This approach allows us to identify the main combination of factors that lead to fast poverty reduction, and the ones that lead to high climate change impacts on the poor. Identifying these factors is critical for designing efficient policies to protect the poorest from climate change impacts and making economic growth more inclusive. Conclusions are twofold. First, by 2030 climate change can have a large impact on poverty, with between 3 and 122 million more people in poverty, but climate change remains a secondary driver of poverty trends within this time horizon. Climate change impacts do not only affect the poorest: in 2030, the bottom 40 percent lose more than 4 percent of income in many countries. The regional hotspots are Sub-Saharan Africa and - to a lesser extent - India and the rest of South Asia. The most important channel through which climate change increases poverty is through agricultural income and food prices. Second, by 2030 and in the absence of surprises on climate impacts, inclusive climate-informed development can prevent most of (but not all) the impacts on poverty. In a scenario with rapid, inclusive and climate-proof development, climate change impact on poverty is

    The production of application software is rapidly being industrialized. Computer manufacturers and software houses produce a rapidly growing number of generic software applications and systems, and more and more user companies choose to build their computer-based information systems...... with such generic products, instead of custom made software. We discuss how the move away from traditional in-house development and the increasing use of generic software is likely to transform IS development in the near future. We conclude that these developments will make new demands on the information systems...

  7. Rapid Microsatellite Marker Development Using Next Generation Pyrosequencing to Inform Invasive Burmese Python—Python molurus bivittatus—Management

    Directory of Open Access Journals (Sweden)

    Kristen M. Hart


    Full Text Available Invasive species represent an increasing threat to native ecosystems, harming indigenous taxa through predation, habitat modification, cross-species hybridization and alteration of ecosystem processes. Additionally, high economic costs are associated with environmental damage, restoration and control measures. The Burmese python, Python molurus bivittatus, is one of the most notable invasive species in the US, due to the threat it poses to imperiled species and the Greater Everglades ecosystem. To address population structure and relatedness, next generation sequencing was used to rapidly produce species-specific microsatellite loci. The Roche 454 GS-FLX Titanium platform provided 6616 di-, tri- and tetra-nucleotide repeats in 117,516 sequences. Using stringent criteria, 24 of 26 selected tri- and tetra-nucleotide loci were polymerase chain reaction (PCR amplified and 18 were polymorphic. An additional six cross-species loci were amplified, and the resulting 24 loci were incorporated into eight PCR multiplexes. Multi-locus genotypes yielded an average of 61% (39%–77% heterozygosity and 3.7 (2–6 alleles per locus. Population-level studies using the developed microsatellites will track the invasion front and monitor population-suppression dynamics. Additionally, cross-species amplification was detected in the invasive Ball, P. regius, and Northern African python, P. sebae. These markers can be used to address the hybridization potential of Burmese pythons and the larger, more aggressive P. sebae.

  11. SU-E-T-23: A Developing Australian Network for Datamining and Modelling Routine Radiotherapy Clinical Data and Radiomics Information for Rapid Learning and Clinical Decision Support

    Energy Technology Data Exchange (ETDEWEB)

    Thwaites, D [University of Sydney, Camperdown, Sydney (Australia); Holloway, L [Ingham Institute, Sydney, NSW (Australia); Bailey, M; Carolan, M; Miller, A [Illawarra Cancer Care Centre, Wollongong, NSW (Australia); Barakat, S; Field, M [University of Sydney, Sydney, NSW (Australia); Delaney, G; Vinod, S [Liverpool Hospital, Liverpool, NSW (Australia); Dekker, A [Maastro Clinic, Maastricht (Netherlands); Lustberg, T; Soest, J van; Walsh, S [MAASTRO Clinic, Maastricht (Netherlands)


    Purpose: Large amounts of routine radiotherapy (RT) data are available, which can potentially add clinical evidence to support better decisions. A developing collaborative Australian network, with a leading European partner, aims to validate, implement and extend European predictive models (PMs) for Australian practice and assess their impact on future patient decisions. Wider objectives include: developing multi-institutional rapid learning, using distributed learning approaches; and assessing and incorporating radiomics information into PMs. Methods: Two initial standalone pilots were conducted; one on NSCLC, the other on larynx, patient datasets in two different centres. Open-source rapid learning systems were installed, for data extraction and mining to collect relevant clinical parameters from the centres’ databases. The European DSSs were learned (“training cohort”) and validated against local data sets (“clinical cohort”). Further NSCLC studies are underway in three more centres to pilot a wider distributed learning network. Initial radiomics work is underway. Results: For the NSCLC pilot, 159/419 patient datasets were identified meeting the PM criteria, and hence eligible for inclusion in the curative clinical cohort (for the larynx pilot, 109/125). Some missing data were imputed using Bayesian methods. For both, the European PMs successfully predicted prognosis groups, but with some differences in practice reflected. For example, the PM-predicted good prognosis NSCLC group was differentiated from a combined medium/poor prognosis group (2YOS 69% vs. 27%, p<0.001). Stage was less discriminatory in identifying prognostic groups. In the good prognosis group two-year overall survival was 65% in curatively and 18% in palliatively treated patients. Conclusion: The technical infrastructure and basic European PMs support prognosis prediction for these Australian patient groups, showing promise for supporting future personalized treatment decisions

    Directory of Open Access Journals (Sweden)

    Viktoria Oline Barrios Poulsen


    Full Text Available Severe cutaneous reactions with potentially fatal outcomes can have many different causes. The Stevens-Johnson syndrome (SJS and toxic epidermal necrolysis (TEN are rare. They are characterized by a low incidence but high mortality, and drugs are most commonly implicated. Urgent active therapy is required. Prompt recognition and withdrawal of suspect drug and rapid intervention can result in favourable outcome. No further international guidelines for treatment exist, and much of the treatment relies on old or experimental concepts with no scientific evidence. We report on a 54-year-old man experiencing rapidly developing drug-induced severe TEN and presented multiorgan failure involving the respiratory and circulatory system, coagulopathy, and renal insufficiency. Detachment counted 30% of total body surface area (TBSA. SCORTEN = 5, indicating a mortality rate >90%. The patient was sedated and mechanically ventilated, supported with fluids and inotropes to maintain a stable circulation. Component therapy was guided by thromboelastography (TEG. The patient received plasmapheresis, and shock reversal treatment was initiated. He was transferred to a specialized intensive care burn unit within 24 hours from admittance. The initial care was continued, and hemodialysis was started. Pulmonary, circulatory, and renal sequelae resolved with intensive care, and re-epithelialization progressed slowly. The patient was discharged home on hospital day 19.

    Energy Technology Data Exchange (ETDEWEB)

    Young, K. R.; Levine, A.


    The Regulatory and Permitting Information Desktop (RAPID) Toolkit combines the former Geothermal Regulatory Roadmap, National Environmental Policy Act (NEPA) Database, and other resources into a Web-based tool that gives the regulatory and utility-scale geothermal developer communities rapid and easy access to permitting information. RAPID currently comprises five tools - Permitting Atlas, Regulatory Roadmap, Resource Library, NEPA Database, and Best Practices. A beta release of an additional tool, the Permitting Wizard, is scheduled for late 2014. Because of the huge amount of information involved, RAPID was developed in a wiki platform to allow industry and regulatory agencies to maintain the content in the future so that it continues to provide relevant and accurate information to users. In 2014, the content was expanded to include regulatory requirements for utility-scale solar and bulk transmission development projects. Going forward, development of the RAPID Toolkit will focus on expanding the capabilities of current tools, developing additional tools, including additional technologies, and continuing to increase stakeholder involvement.

  3. YAM- A Framework for Rapid Software Development (United States)

    Jain, Abhinandan; Biesiadecki, Jeffrey


    YAM is a software development framework with tools for facilitating the rapid development and integration of software in a concurrent software development environment. YAM provides solutions for thorny development challenges associated with software reuse, managing multiple software configurations, the development of software product-lines, multiple platform development and build management. YAM uses release-early, release-often development cycles to allow developers to incrementally integrate their changes into the system on a continual basis. YAM facilitates the creation and merging of branches to support the isolated development of immature software to avoid impacting the stability of the development effort. YAM uses modules and packages to organize and share software across multiple software products. It uses the concepts of link and work modules to reduce sandbox setup times even when the code-base is large. One side-benefit is the enforcement of a strong module-level encapsulation of a module s functionality and interface. This increases design transparency, system stability as well as software reuse. YAM is in use by several mid-size software development teams including ones developing mission-critical software.

  4. Rapid Glass Refiner Development Program, Final report

    Energy Technology Data Exchange (ETDEWEB)



    A rapid glass refiner (RGR) technology which could be applied to both conventional and advanced class melting systems would significantly enhance the productivity and the competitiveness of the glass industry in the United States. Therefore, Vortec Corporation, with the support of the US Department of Energy (US DOE) under Cooperative Agreement No. DE-FC07-90ID12911, conducted a research and development program for a unique and innovative approach to rapid glass refining. To provide focus for this research effort, container glass was the primary target from among the principal glass types based on its market size and potential for significant energy savings. Container glass products represent the largest segment of the total glass industry accounting for 60% of the tonnage produced and over 40% of the annual energy consumption of 232 trillion Btu/yr. Projections of energy consumption and the market penetration of advanced melting and fining into the container glass industry yield a potential energy savings of 7.9 trillion Btu/yr by the year 2020.

  5. A rapid review of consumer health information needs and preferences. (United States)

    Ramsey, Imogen; Corsini, Nadia; Peters, Micah D J; Eckert, Marion


    This rapid review summarizes best available evidence on consumers' needs and preferences for information about healthcare, with a focus on the Australian context. Three questions are addressed: 1) Where do consumers find and what platform do they use to access information about healthcare? 2) How do consumers use the healthcare information that they find? 3) About which topics or subjects do consumers need healthcare information? A hierarchical approach was adopted with evidence first sought from reviews then high quality studies using Medline (via PubMed), CINAHL, Embase, the JBI Database of Systematic Reviews and Implementation Reports, the Campbell Collaboration Library of Systematic Reviews, EPPI-Centre, and Epistemonikos. Twenty-eight articles were included; four systematic reviews, three literature reviews, thirteen quantitative studies, six qualitative studies, and two mixed methods studies. Consumers seek health information at varying times along the healthcare journey and through various modes of delivery. Complacency with historical health information modes is no longer appropriate and flexibility is essential to suit growing consumer demands. Health information should be readily available in different formats and not exclusive to any single medium. Copyright © 2017. Published by Elsevier B.V.

    Methods and systems for rapid automatic keyword extraction for information retrieval and analysis. Embodiments can include parsing words in an individual document by delimiters, stop words, or both in order to identify candidate keywords. Word scores for each word within the candidate keywords are then calculated based on a function of co-occurrence degree, co-occurrence frequency, or both. Based on a function of the word scores for words within the candidate keyword, a keyword score is calculated for each of the candidate keywords. A portion of the candidate keywords are then extracted as keywords based, at least in part, on the candidate keywords having the highest keyword scores.

  7. Incorporating indel information into phylogeny estimation for rapidly emerging pathogens

    Directory of Open Access Journals (Sweden)

    Suchard Marc A


    Full Text Available Abstract Background Phylogenies of rapidly evolving pathogens can be difficult to resolve because of the small number of substitutions that accumulate in the short times since divergence. To improve resolution of such phylogenies we propose using insertion and deletion (indel information in addition to substitution information. We accomplish this through joint estimation of alignment and phylogeny in a Bayesian framework, drawing inference using Markov chain Monte Carlo. Joint estimation of alignment and phylogeny sidesteps biases that stem from conditioning on a single alignment by taking into account the ensemble of near-optimal alignments. Results We introduce a novel Markov chain transition kernel that improves computational efficiency by proposing non-local topology rearrangements and by block sampling alignment and topology parameters. In addition, we extend our previous indel model to increase biological realism by placing indels preferentially on longer branches. We demonstrate the ability of indel information to increase phylogenetic resolution in examples drawn from within-host viral sequence samples. We also demonstrate the importance of taking alignment uncertainty into account when using such information. Finally, we show that codon-based substitution models can significantly affect alignment quality and phylogenetic inference by unrealistically forcing indels to begin and end between codons. Conclusion These results indicate that indel information can improve phylogenetic resolution of recently diverged pathogens and that alignment uncertainty should be considered in such analyses.

  8. Generalization of prior information for rapid Bayesian time estimation. (United States)

    Roach, Neil W; McGraw, Paul V; Whitaker, David J; Heron, James


    To enable effective interaction with the environment, the brain combines noisy sensory information with expectations based on prior experience. There is ample evidence showing that humans can learn statistical regularities in sensory input and exploit this knowledge to improve perceptual decisions and actions. However, fundamental questions remain regarding how priors are learned and how they generalize to different sensory and behavioral contexts. In principle, maintaining a large set of highly specific priors may be inefficient and restrict the speed at which expectations can be formed and updated in response to changes in the environment. However, priors formed by generalizing across varying contexts may not be accurate. Here, we exploit rapidly induced contextual biases in duration reproduction to reveal how these competing demands are resolved during the early stages of prior acquisition. We show that observers initially form a single prior by generalizing across duration distributions coupled with distinct sensory signals. In contrast, they form multiple priors if distributions are coupled with distinct motor outputs. Together, our findings suggest that rapid prior acquisition is facilitated by generalization across experiences of different sensory inputs but organized according to how that sensory information is acted on.

  9. A digital social network for rapid collection of earthquake disaster information (United States)

    Xu, J. H.; Nie, G. Z.; Xu, X.


    Acquiring disaster information quickly after an earthquake is crucial for disaster and emergency rescue management. This study examines a digital social network - an earthquake disaster information reporting network - for rapid collection of earthquake disaster information. Based on the network, the disaster information rapid collection method is expounded in this paper. The structure and components of the reporting network are introduced. Then the work principles of the reporting network are discussed, in which the rapid collection of disaster information is realised by using Global System for Mobile Communications (GSM) messages to report the disaster information and Geographic information system (GIS) to analyse and extract useful disaster information. This study introduces some key technologies for the work principles, including the methods of mass sending and receiving of SMS for disaster management, the reporting network grouping management method, brief disaster information codes, and the GIS modelling of the reporting network. Finally, a city earthquake disaster information quick reporting system is developed and with the support of this system the reporting network obtained good results in a real earthquake and earthquake drills. This method is a semi-real time disaster information collection method which extends current SMS based method and meets the need of small and some moderate earthquakes.

  11. Rapidly developing iatrogenic hyponatremia in a child following tonsillectomy. (United States)

    Taskin, Umit; Binay, Omer; Binay, Cigdem; Yigit, Ozgur


    Hyponatremia develops as a result of the inappropriate secretion of antidiuretic hormone. In rare cases, it develops as an iatrogenic complication. For example, acute iatrogenic post-tonsillectomy hyponatremia has been described in children following the infusion of hypo- or isotonic fluid. We report a case of rapidly developing post-tonsillectomy iatrogenic hyponatremia in a 5-year-old girl following an excessive infusion of hypotonic fluid. Her signs and symptoms began with nausea and vomiting and progressed to seizures and coma. We corrected the electrolyte disturbance by infusing a 3% sodium chloride solution until her neurologic manifestations disappeared, at which time her serum sodium concentration had risen back to 135 mEq/L. Otolaryngologists are not generally exposed to much information about hyponatremia, so we must be aware of its associated neurologic signs and symptoms.

  12. Rapid sampling of molecular motions with prior information constraints.

    Directory of Open Access Journals (Sweden)

    Barak Raveh


    Full Text Available Proteins are active, flexible machines that perform a range of different functions. Innovative experimental approaches may now provide limited partial information about conformational changes along motion pathways of proteins. There is therefore a need for computational approaches that can efficiently incorporate prior information into motion prediction schemes. In this paper, we present PathRover, a general setup designed for the integration of prior information into the motion planning algorithm of rapidly exploring random trees (RRT. Each suggested motion pathway comprises a sequence of low-energy clash-free conformations that satisfy an arbitrary number of prior information constraints. These constraints can be derived from experimental data or from expert intuition about the motion. The incorporation of prior information is very straightforward and significantly narrows down the vast search in the typically high-dimensional conformational space, leading to dramatic reduction in running time. To allow the use of state-of-the-art energy functions and conformational sampling, we have integrated this framework into Rosetta, an accurate protocol for diverse types of structural modeling. The suggested framework can serve as an effective complementary tool for molecular dynamics, Normal Mode Analysis, and other prevalent techniques for predicting motion in proteins. We applied our framework to three different model systems. We show that a limited set of experimentally motivated constraints may effectively bias the simulations toward diverse predicates in an outright fashion, from distance constraints to enforcement of loop closure. In particular, our analysis sheds light on mechanisms of protein domain swapping and on the role of different residues in the motion.

    To review and summarize the development during the last 20 years and the current status of cosmetic medicine, i.e., cosmetic surgery, in China, for the healthier development of this specialty in the future. Literature concerned was reviewed, including conference abstracts, papers, and publications, and the present status and problems were analyzed. Cosmetic medicine was recognized as an independent specialty and gained its clear definition. The development of cosmetic medicine is an inevitable trend of the changing medical modules and the developing science and civilization. This trend fulfilled the need of the people. The related problems consisted of a high complication rate, confusion of management, and insufficient specific knowledge in part of the providers. The development of cosmetic medicine is an inevitable trend of the civilization development. For the healthy development of this specialty, scientific management and systemic education for the providers are crucial. Only those who have the plastic surgery background are able to participate in this practice.

  17. Rapid Development of Intestinal Type Gastric Adenocarcinoma

    Directory of Open Access Journals (Sweden)

    Young S. Oh


    Full Text Available Intestinal type gastric adenocarcinoma is felt to develop over a protracted time period through a series of defined steps. Several potential risk factors for the development of gastric cancer have been identified, including a family history of gastric cancer and Helicobacter pylori infection. We present the case of a patient with neither risk factor who progressed in a 14 month time frame from histologically normal gastric mucosa to early stage intestinal type gastric adenocarcinoma in the setting of diffuse gastric intestinal metaplasia and atrophic gastritis. This patient’s presentation conflicts with our current understanding of the development of intestinal type gastric adenocarcinoma.

  18. [The rapid development of child neuropsychology]. (United States)

    Billard, C; Jambaqué, I


    The past few years have seen important progress and new developments in the field of child neuropsychology. Children can exhibit acquired or learning disorders, but in all cases such deficits take place in a developmental trajectory that requires taking into account cerebral maturation and plasticity processes. Child neuropsychology finds its specificity in the perspective of developmental neuropsychology and has close connections with health and education. This article focuses on two pathologies - childhood epilepsies and developmental dyslexia - that highlight the recent progress in this specialty and its perspectives.

  1. Rapid Response Risk Assessment in New Project Development (United States)

    Graber, Robert R.


    A capability for rapidly performing quantitative risk assessments has been developed by JSC Safety and Mission Assurance for use on project design trade studies early in the project life cycle, i.e., concept development through preliminary design phases. A risk assessment tool set has been developed consisting of interactive and integrated software modules that allow a user/project designer to assess the impact of alternative design or programmatic options on the probability of mission success or other risk metrics. The risk and design trade space includes interactive options for selecting parameters and/or metrics for numerous design characteristics including component reliability characteristics, functional redundancy levels, item or system technology readiness levels, and mission event characteristics. This capability is intended for use on any project or system development with a defined mission, and an example project will used for demonstration and descriptive purposes, e.g., landing a robot on the moon. The effects of various alternative design considerations and their impact of these decisions on mission success (or failure) can be measured in real time on a personal computer. This capability provides a high degree of efficiency for quickly providing information in NASA s evolving risk-based decision environment

    Objective To test how genomic loci identified in genome-wide association studies influence the development of obesity. Design A 38-year prospective longitudinal study of a representative birth cohort. Setting The Dunedin Multidisciplinary Health and Development Study, Dunedin, New Zealand. Participants One thousand thirty-seven male and female study members. Main Exposures We assessed genetic risk with a multilocus genetic risk score. The genetic risk score was composed of single-nucleotide polymorphisms identified in genome-wide association studies of obesity-related phenotypes. We assessed family history from parent body mass index data collected when study members were 11 years of age. Main Outcome Measures Body mass index growth curves, developmental phenotypes of obesity, and adult obesity outcomes were defined from anthropometric assessments at birth and at 12 subsequent in-person interviews through 38 years of age. Results Individuals with higher genetic risk scores were more likely to be chronically obese in adulthood. Genetic risk first manifested as rapid growth during early childhood. Genetic risk was unrelated to birth weight. After birth, children at higher genetic risk gained weight more rapidly and reached adiposity rebound earlier and at a higher body mass index. In turn, these developmental phenotypes predicted adult obesity, mediating about half the genetic effect on adult obesity risk. Genetic associations with growth and obesity risk were independent of family history, indicating that the genetic risk score could provide novel information to clinicians. Conclusions Genetic variation linked with obesity risk operates, in part, through accelerating growth in the early childhood years after birth. Etiological research and prevention strategies should target early childhood to address the obesity epidemic. PMID:22665028

  5. Social media as an information source for rapid flood inundation mapping (United States)

    Fohringer, J.; Dransch, D.; Kreibich, H.; Schröter, K.


    During and shortly after a disaster, data about the hazard and its consequences are scarce and not readily available. Information provided by eyewitnesses via social media is a valuable information source, which should be explored in a~more effective way. This research proposes a methodology that leverages social media content to support rapid inundation mapping, including inundation extent and water depth in the case of floods. The novelty of this approach is the utilization of quantitative data that are derived from photos from eyewitnesses extracted from social media posts and their integration with established data. Due to the rapid availability of these posts compared to traditional data sources such as remote sensing data, areas affected by a flood, for example, can be determined quickly. The challenge is to filter the large number of posts to a manageable amount of potentially useful inundation-related information, as well as to interpret and integrate the posts into mapping procedures in a timely manner. To support rapid inundation mapping we propose a methodology and develop "PostDistiller", a tool to filter geolocated posts from social media services which include links to photos. This spatial distributed contextualized in situ information is further explored manually. In an application case study during the June 2013 flood in central Europe we evaluate the utilization of this approach to infer spatial flood patterns and inundation depths in the city of Dresden.

  11. Methods for Rapid Screening in Woody Plant Herbicide Development

    Directory of Open Access Journals (Sweden)

    William Stanley


    Full Text Available Methods for woody plant herbicide screening were assayed with the goal of reducing resources and time required to conduct preliminary screenings for new products. Rapid screening methods tested included greenhouse seedling screening, germinal screening, and seed screening. Triclopyr and eight experimental herbicides from Dow AgroSciences (DAS 313, 402, 534, 548, 602, 729, 779, and 896 were tested on black locust, loblolly pine, red maple, sweetgum, and water oak. Screening results detected differences in herbicide and species in all experiments in much less time (days to weeks than traditional field screenings and consumed significantly less resources (<500 mg acid equivalent per herbicide per screening. Using regression analysis, various rapid screening methods were linked into a system capable of rapidly and inexpensively assessing herbicide efficacy and spectrum of activity. Implementation of such a system could streamline early-stage herbicide development leading to field trials, potentially freeing resources for use in development of beneficial new herbicide products.

  12. Economic Growth of a Rapidly Developing Economy: Theoretical Formulation

    Directory of Open Access Journals (Sweden)

    Oleg Sergeyevich Sukharev


    Full Text Available The subject matter of the article is the description of economic growth. Modern economy is characterized by a high rate of changes. These changes are the limiting parameters of modern development, which requires a modification of the basic models of growth, the substantiation of the expediency and necessity of a rapid development strategy. In a simple mathematical form, the statement of the problem of economic growth in the “green economy” is examined, in which the costs of environmental measures are not considered a priori as hampering economic development (as it is common for a number of modern neoclassical and neo-Keynesian growth models. The methodological basis of the article are the econometric approach and modelling method. The article has a theoretical character. The main hypothesis supposes that the rapid development strategy cannot make an adequate development strategy under certain conditions, but may be acceptable in other its specific conditions. In this sense, the important growth conditions are the availability of resources, the effectiveness of institutions and the current economic structure, the technological effectiveness of economy, as well as the conditions of technological development (“green economy” and the path of such development. In the article, on the theoretical level of analysis, the substantiation of the adequacy of the rapid development strategy for an economic system is given, whose goal is to achieve the standard of living of the countryleader. Based on the assumptions introduced, the period for which the rapid development strategy might be implemented and the economic lag of the country might be reduced from the country-leader is determined. The conditions that ensure the impact of innovations on the rate of economic development are summarized. The introduced range of dependencies and relations can be useful for the elaboration of the theory of innovation development and for the formation of a new

    -Army (Global Combat Support System-Army Field/Tactical, is intended for the tactical level and it will replace 14 tactical logistics information systems and connect them with the rest of the information environment. Tendencies in the development of logistics information systems In line with the presented information solutions, it is possible to extract relevant conclusions about tendencies in the development of these types of systems all around the world. These conclusions should be implemented, through adequate principles, into domestic software development. Three main tendencies are visible in modern solutions: using centralised databases, integration of existing separated software solutions, and connecting previously autonomus systems. Conclusion In accordance with present time requirements, logistic support should be realised as close as possible to the origin of a logistic need, in real time and adequately. Information systems enable real time delivery of information needed for a quality logistic support in all phases of operations as well as for a faster generation of all types of documents.

    The Priest Rapids Dam is located on the Columbia River and is operated by Public Utility District No. 2 of Grant County, WA (GCPUD). In operation since 1959, GCPUD decided that a major upgrade was necessary. As with other hydroelectric facilities on the Columbia River, improving fish passage at Priest Rapids Dam is of great importance for salmon and steelhead populations in the Pacific Northwest. Consequently, GCPUD established the Priest Rapids Turbine Upgrade Project to extend the life of the units, increase efficiency and power production, and improve fish-passage. The Priest Rapids powerhouse is equipped with 10 vertical Kaplan turbines with runner diameters of 7.21 m operating under net heads varying from 18 m to 27 m. The scope of the project included a design competition involving three turbine manufacturers providing up to two designs for evaluation. Selection of the replacement design was determined by the lowest evaluated price based on model test results conducted at an independent laboratory (Ecole Polytechnique Federale de Lausanne in Lausanne Switzerland) and a biological performance score determined by a newly developed Biological Performance Assessment (BioPA) performed by Pacific Northwest National Laboratory in Richland, WA. In the paper, the hydraulic design challenges are reviewed, in addition to comparisons of designs evaluated during the competitive model test program and biological assessment. The paper also provides a description of the process followed by GCPUD, and how the evaluation criteria influenced the development and the finally selected solution.

  17. Onboard Radar Processing Development for Rapid Response Applications (United States)

    Lou, Yunling; Chien, Steve; Clark, Duane; Doubleday, Josh; Muellerschoen, Ron; Wang, Charles C.


    We are developing onboard processor (OBP) technology to streamline data acquisition on-demand and explore the potential of the L-band SAR instrument onboard the proposed DESDynI mission and UAVSAR for rapid response applications. The technology would enable the observation and use of surface change data over rapidly evolving natural hazards, both as an aid to scientific understanding and to provide timely data to agencies responsible for the management and mitigation of natural disasters. We are adapting complex science algorithms for surface water extent to detect flooding, snow/water/ice classification to assist in transportation/ shipping forecasts, and repeat-pass change detection to detect disturbances. We are near completion of the development of a custom FPGA board to meet the specific memory and processing needs of L-band SAR processor algorithms and high speed interfaces to reformat and route raw radar data to/from the FPGA processor board. We have also developed a high fidelity Matlab model of the SAR processor that is modularized and parameterized for ease to prototype various SAR processor algorithms targeted for the FPGA. We will be testing the OBP and rapid response algorithms with UAVSAR data to determine the fidelity of the products.

  18. Rapid development of fungicide resistance by Sclerotinia homoeocarpa on turfgrass. (United States)

    Jo, Young-Ki; Chang, Seog Won; Boehm, Michael; Jung, Geunhwa


    Dollar spot, caused by Sclerotinia homoeocarpa, is the most prevalent and economically important turfgrass disease in North America. Increasing levels of fungicide resistance, coupled with tightening environmental scrutiny of existing fungicides, has left fewer options for managing dollar spot. More knowledge about S. homoeocarpa populations is needed to improve dollar spot management strategies, especially with respect to minimizing the development of fungicide resistance. Population diversity of S. homoeocarpa was examined using inter-simple sequence repeat markers and vegetative compatibility assays. Two subgroups were found in S. homoeocarpa field populations on both fairway and putting green turfgrass at a research field in Wisconsin. These subgroups were genetically different, vegetatively incompatible, and had different fungicide sensitivities. The frequency of the two genetic subgroups differed significantly between the fairway and putting green, but was uniform within the fairway or within the green. Population dynamics of S. homoeocarpa in response to two systemic fungicides (thiophanate-methyl and propiconazole) were assessed based on in vitro fungicide sensitivity. Dynamics of S. homoeocarpa populations depended on the presence of fungicide-resistant isolates in the initial populations before fungicide applications and changed rapidly after fungicide applications. Shifting of the population toward propiconazole resistance was gradual, whereas thiophanate-methyl resistance developed rapidly in the population. In conclusion, field populations of S. homoeocarpa containing genetically distinct, vegetatively incompatible groups were different on turfgrass that was managed differently, and they were changed rapidly after exposure to fungicides.

  19. Modeling of subglacial hydrological development following rapid supraglacial lake drainage (United States)

    Dow, C. F.; Kulessa, B.; Rutt, I. C.; Tsai, V. C.; Pimentel, S.; Doyle, S. H.; van As, D.; Lindbäck, K.; Pettersson, R.; Jones, G. A.; Hubbard, A.


    The rapid drainage of supraglacial lakes injects substantial volumes of water to the bed of the Greenland ice sheet over short timescales. The effect of these water pulses on the development of basal hydrological systems is largely unknown. To address this, we develop a lake drainage model incorporating both (1) a subglacial radial flux element driven by elastic hydraulic jacking and (2) downstream drainage through a linked channelized and distributed system. Here we present the model and examine whether substantial, efficient subglacial channels can form during or following lake drainage events and their effect on the water pressure in the surrounding distributed system. We force the model with field data from a lake drainage site, 70 km from the terminus of Russell Glacier in West Greenland. The model outputs suggest that efficient subglacial channels do not readily form in the vicinity of the lake during rapid drainage and instead water is evacuated primarily by a transient turbulent sheet and the distributed system. Following lake drainage, channels grow but are not large enough to reduce the water pressure in the surrounding distributed system, unless preexisting channels are present throughout the domain. Our results have implications for the analysis of subglacial hydrological systems in regions where rapid lake drainage provides the primary mechanism for surface-to-bed connections.

  20. Developing an information systems strategy for nursing. (United States)

    Callanan, K M; Hughes, S J


    With the rapidly changing health care environment and information technology advances, organizations need to engage in strategic, planned change in order to allocate limited resources, achieve the organization's goals, and fulfill its mission [1]. One of the most important aspects of the organization's planned strategies for change concerns the information systems. The involvement of the nursing department in this process is critical. This poster presentation will communicate how nurses can develop an information systems strategic plan that will enable them to play an active role as contributors and vital participants in the strategic and business planning processes for information systems. This information systems strategy for nursing will: a) provide direction and purpose, b) guide nursing in identifying the kinds of information technology needed, c) assist in timely implementation of a system that supports nursing, and d) identify desired outcomes and benefits of an information system. The nursing information systems plan must be built on, and support, the organization's mission and business plan and integrate into the over-all information systems plans [2]. Components of the nursing strategic plan include the nursing mission statement and vision, an assessment of the current environment to identify supporting technology needed to achieve the nursing vision, expectations/anticipated outcomes, environmental considerations, and special staffing/expertise considerations. The nursing vision and mission statement is an articulation of the overall direction and purpose of the nursing organization. An assessment of the nursing organization, problem areas, opportunities for growth, the physical environment, existing systems, communications requirements, and resources is carried out to help identify areas where new technologies and automated methods of managing information could be applied. Special staffing and expertise not currently available in the organization, but

  2. Using Rapid Improvement Events for Disaster After-Action Reviews: Experience in a Hospital Information Technology Outage and Response. (United States)

    Little, Charles M; McStay, Christopher; Oeth, Justin; Koehler, April; Bookman, Kelly


    The use of after-action reviews (AARs) following major emergency events, such as a disaster, is common and mandated for hospitals and similar organizations. There is a recurrent challenge of identified problems not being resolved and repeated in subsequent events. A process improvement technique called a rapid improvement event (RIE) was used to conduct an AAR following a complete information technology (IT) outage at a large urban hospital. Using RIE methodology to conduct the AAR allowed for the rapid development and implementation of major process improvements to prepare for future IT downtime events. Thus, process improvement methodology, particularly the RIE, is suited for conducting AARs following disasters and holds promise for improving outcomes in emergency management.

  3. Use of basic biological information for rapid prediction of the response of species to habitat loss. (United States)

    Hockey, Philip A R; Curtis, Odette E


    Much research has focused on identifying traits that can act as useful indicators of how habitat loss affects the extinction risk of species, and the results are mixed. We developed 2 simple, rapid-assessment models of the susceptibility of species to habitat loss. We based both on an index of range size, but one also incorporated an index of body mass and the other an index combining habitat and dietary specialization. We applied the models to samples of birds (Accipitridae and Bucerotidae) and to the lemurs of Madagascar and compared the models' classifications of risk with the IUCN's global threat status of each species. The model derived from ecological attributes was much more robust than the one derived from body mass. Ecological attributes identified threatened birds and lemurs with an average of 80% accuracy and endangered and critically endangered species with 100% accuracy and identified some species not currently listed as threatened that almost certainly warrant conservation consideration. Appropriate analysis of even fairly crude biological information can help raise early-warning flags to the relative susceptibilities of species to habitat loss and thus provide a useful and rapid technique for highlighting potential species-level conservation issues. Advantages of this approach to classifying risk include flexibility in the specialization parameters used as well as its applicability at a range of spatial scales.

  4. Development of Nylon Based FDM Filament for Rapid Tooling Application (United States)

    Singh, R.; Singh, S.


    There has been critical need for development of cost effective nylon based wire to be used as feed stock filament for fused deposition modelling (FDM) machine. But hitherto, very less work has been reported for development of alternate solution of acrylonitrile butadiene styrene (ABS) based wire which is presently used in most of FDM machines. The present research work is focused on development of nylon based wire as an alternative of ABS wire (which is to be used as feedstock filament on FDM) without changing any hardware or software of machine. For the present study aluminium oxide (Al2O3) as additive in different proportion has been used with nylon fibre. Single screw extruder was used for wire preparation and wire thus produced was tested on FDM. Mechanical properties i.e. tensile strength and percentage elongation of finally developed wire have been optimized by Taguchi L9 technique. The work represented major development in reducing cost and time in rapid tooling applications.

  5. Microstructural development of rapid solidification in Al-Si powder

    Energy Technology Data Exchange (ETDEWEB)

    Jin, Feng [Iowa State Univ., Ames, IA (United States)


    The microstructure and the gradient of microstructure that forms in rapidly solidificated powder were investigated for different sized particles. High pressure gas atomization solidification process has been used to produce a series of Al-Si alloys powders between 0.2 μm to 150 μm diameter at the eutectic composition (12.6 wt pct Si). This processing technique provides powders of different sizes which solidify under different conditions (i.e. interface velocity and interface undercooling), and thus give different microstructures inside the powders. The large size powder shows dendritic and eutectic microstructures. As the powder size becomes smaller, the predominant morphology changes from eutectic to dendritic to cellular. Microstructures were quantitatively characterized by using optical microscope and SEM techniques. The variation in eutectic spacing within the powders were measured and compared with the theoretical model to obtain interface undercooling, and growth rate during the solidification of a given droplet. Also, nucleation temperature, which controls microstructures in rapidly solidified fine powders, was estimated. A microstructural map which correlates the microstructure with particle size and processing parameters is developed.

  6. Microstructural Development in Al-Si Powder During Rapid Solidification

    Energy Technology Data Exchange (ETDEWEB)

    Genau, Amber Lynn [Iowa State Univ., Ames, IA (United States)


    Powder metallurgy has become an increasingly important form of metal processing because of its ability to produce materials with superior mechanical properties. These properties are due in part to the unique and often desirable microstructures which arise as a result of the extreme levels of undercooling achieved, especially in the finest size powder, and the subsequent rapid solidification which occurs. A better understanding of the fundamental processes of nucleation and growth is required to further exploit the potential of rapid solidification processing. Aluminum-silicon, an alloy of significant industrial importance, was chosen as a model for simple eutectic systems displaying an unfaceted/faceted interface and skewed coupled eutectic growth zone, Al-Si powder produced by high pressure gas atomization was studied to determine the relationship between microstructure and alloy composition as a function of powder size and atomization gas. Critical experimental measurements of hypereutectic (Si-rich) compositions were used to determine undercooling and interface velocity, based on the theoretical models which are available. Solidification conditions were analyzed as a function of particle diameter and distance from nucleation site. A revised microstructural map is proposed which allows the prediction of particle morphology based on temperature and composition. It is hoped that this work, by providing enhanced understanding of the processes which govern the development of the solidification morphology of gas atomized powder, will eventually allow for better control of processing conditions so that particle microstructures can be optimized for specific applications.

  9. Rapid Development of Bespoke Unmanned Platforms for Atmospheric Science (United States)

    Sobester, A.; Johnston, S. J.; Scanlan, J. P.; Hart, E. E.; O'Brien, N. S.


    The effective deployment of airborne atmospheric science instruments often hinges on the development cycle time of a suitable platform, one that is capable of delivering them to the desired altitude range for a specified amount of time, along a pre-determined trajectory. This could be driven by the need to respond rapidly to sudden, unexpected events (e.g., volcano eruptions, nuclear fallout, etc.) or simply to accommodate the iterative design and flight test cycle of the instrument developer. A shorter development cycle time would also afford us the ability to quickly adapt the hardware and control logic in response to unexpected results during an experimental campaign. We report on recent developments aimed at meeting this demand. As part of the Atmospheric Science Through Robotic Aircraft (ASTRA) initiative we have investigated the use of rapid prototyping technologies to this end, both on the 'airframe' of the platform itself and on the on-board systems. We show how fast multi-disciplinary design optimization techniques, coupled with computer-controlled additive manufacturing (3D printing) and laser cutting methods and electronic prototyping (using standard, modular, programmable building blocks) can lead to the delivery of a fully customized platform integrating a given instrument in a timescale of the order of ten days. Specific examples include the design and testing of a balloon-launched glider sensorcraft and a stratospheric balloon system. The 'vehicle' for the latter was built on a 3D printer using a copolymer thermoplastic material and fitted with a sacrificial protective 'cage' laser-cut from an open-cell foam. The data logging, tracking, sensor integration and communications services of the platform were constructed using the .net Gadgeteer open source hardware kit. The flight planning and eventual post-flight recovery of the system is enabled by a generic, stochastic trajectory simulation tool, also developed as part of the ASTRA initiative. This

    Tang, Clive K. K.; Moseler, Kathy; Levi, Sami


    One important factor in deciding the success of a new consumer product or integrated circuit is minimized time-to- market. A rapid prototyping methodology that encompasses algorithm development in the hardware design phase will have great impact on reducing time-to-market. In this paper, a proven hardware design methodology and a novel top-down design methodology based on Frontier Design's DSP Station tool are described. The proven methodology was used during development of the MC149570 H.261/H.263 video codec manufactured by Motorola. This paper discusses an improvement to this method to create an integrated environment for both system and hardware development, thereby further reducing the time-to-market. The software tool chosen is DSP Station tool by Frontier Design. The rich features of DSP Station tool will be described and then it will be shown how these features may be useful in designing from algorithm to silicon. How this methodology may be used in the development of a new MPEG4 Video Communication ASIC will be outlined. A brief comparison with a popular tool, Signal Processing WorkSystem tool by Cadence, will also be given.

    Simonato, Pierluigi; Bersani, Francesco S; Santacroce, Rita; Cinosi, Eduardo; Schifano, Fabrizio; Bersani, Giuseppe; Martinotti, Giovanni; Corazza, Ornella


    The diffusion of novel psychoactive substances (NPSs), combined with the ability of the Internet to act as an online marketplace, has led to unprecedented challenges for governments, health agencies, and substance misuse services. Despite increasing research, there is a paucity of reliable information available to professionals working in the field. The paper will present the pilot results of the first mobile application (SMAIL) for rapid information sharing on NPSs among health professionals. The development of SMAIL was divided into 2 parts: (a) the creation of the application for registered users, enabling them to send an SMS or email with the name or "street name" of an NPS and receive within seconds emails or SMS with the information, when available and (b) the development of a database to support the incoming requests. One hundred twenty-two professionals based in 22 countries used the service over the pilot period of 16 months (from May 2012 to September 2013). Five hundred fifty-seven enquires were made. Users received rapid information on NPSs, and 61% of them rated the service as excellent. This is the right time to use mobile phone technologies for rapid information sharing and prevention activities on NPSs. Copyright © 2017 John Wiley & Sons, Ltd.

  15. Cerebellum of the Premature Infant: Rapidly Developing, Vulnerable, Clinically Important (United States)

    Volpe, Joseph J.


    Brain abnormality in surviving premature infants is associated with an enormous amount of neurodevelopmental disability, manifested principally by cognitive, behavioral, attentional, and socialization deficits, most commonly with only relatively modest motor deficits. The most recognized contributing neuropathology is cerebral white matter injury. The thesis of this review is that acquired cerebellar abnormality is a relatively less recognized but likely important cause of neurodevelopmental disability in small premature infants. The cerebellar disease may be primarily destructive (eg, hemorrhage, infarction) or primarily underdevelopment. The latter appears to be especially common and relates to a particular vulnerability of the cerebellum of the small premature infant. Central to this vulnerability are the extraordinarily rapid and complex developmental events occurring in the cerebellum. The disturbance of development can be caused either by direct adverse effects on the cerebellum, especially the distinctive transient external granular layer, or by indirect remote trans-synaptic effects. This review describes the fascinating details of cerebellar development, with an emphasis on events in the premature period, the major types of cerebellar abnormality acquired during the premature period, their likely mechanisms of occurrence, and new insights into the relation of cerebellar disease in early life to subsequent cognitive/behavioral/attentional/socialization deficits.

    This document is a guide to the common environmental features of computing in (and around) the RHIC Accelerator Physics.sectio on the 'zoo' cluster of UNJX workstations, in RAPIDE, the RHIC Accelerator Physics Intrepid Development Environment It is hoped tliat later revisions of this document will approach a more professional 'style guide', beyond the convenient collection of pointers and hints presented here. RAP does two kinds of computing, "controls" and "general", addressed in sections 2 and 3 of this document For general computing, efficient system administration requires cooperation in using a common environment There is a much stronger need to define - and adhere to - a commonly agreed set of styles (or rules) in developing controls software. Right now, these rules have been set "de facto". Future improvements to the controls environment, particularly in response to the opinions of users, depends on broad knowledge of what the rules are. There are environmental issues that are basic to both controls and general computing, and that are so fundamental that they are (almost) unarguable. They are described immediately below, in the next section.

  19. Aniline Is Rapidly Converted Into Paracetamol Impairing Male Reproductive Development. (United States)

    Holm, Jacob Bak; Chalmey, Clementine; Modick, Hendrik; Jensen, Lars Skovgaard; Dierkes, Georg; Weiss, Tobias; Jensen, Benjamin Anderschou Holbech; Nørregård, Mette Marie; Borkowski, Kamil; Styrishave, Bjarne; Martin Koch, Holger; Mazaud-Guittot, Severine; Jegou, Bernard; Kristiansen, Karsten; Kristensen, David Møbjerg


    Industrial use of aniline is increasing worldwide with production estimated to surpass 5.6 million metric tons in 2016. Exposure to aniline occurs via air, diet, and water augmenting the risk of exposing a large number of individuals. Early observations suggest that aniline is metabolized to paracetamol/acetaminophen, likely explaining the omnipresence of low concentrations of paracetamol in European populations. This is of concern as recent studies implicate paracetamol as a disrupter of reproduction. Here, we show through steroidogenic profiling that exposure to aniline led to increased levels of the Δ4 steroids, suggesting that the activity of CYP21 was decreased. By contrast, paracetamol decreased levels of androgens likely through inhibition of CYP17A1 activity. We confirm that aniline in vivo is rapidly converted to paracetamol by the liver. Intrauterine exposure to aniline and paracetamol in environmental and pharmaceutical relevant doses resulted in shortening of the anogenital distance in mice, a sensitive marker of fetal androgen levels that in humans is associated with reproductive malformations and later life reproductive disorders. In conclusion, our results provide evidence for a scenario where aniline, through its conversion into antiandrogenic paracetamol, impairs male reproductive development. © The Author 2015.

  20. Development of Multiple Big Data Analytics Platforms with Rapid Response

    Directory of Open Access Journals (Sweden)

    Bao Rong Chang


    Full Text Available The crucial problem of the integration of multiple platforms is how to adapt for their own computing features so as to execute the assignments most efficiently and gain the best outcome. This paper introduced the new approaches to big data platform, RHhadoop and SparkR, and integrated them to form a high-performance big data analytics with multiple platforms as part of business intelligence (BI to carry out rapid data retrieval and analytics with R programming. This paper aims to develop the optimization for job scheduling using MSHEFT algorithm and implement the optimized platform selection based on computing features for improving the system throughput significantly. In addition, users would simply give R commands rather than run Java or Scala program to perform the data retrieval and analytics in the proposed platforms. As a result, according to performance index calculated for various methods, although the optimized platform selection can reduce the execution time for the data retrieval and analytics significantly, furthermore scheduling optimization definitely increases the system efficiency a lot.

  1. Drosophila provides rapid modeling of renal development, function, and disease (United States)

    Romero, Michael F.


    The evolution of specialized excretory cells is a cornerstone of the metazoan radiation, and the basic tasks performed by Drosophila and human renal systems are similar. The development of the Drosophila renal (Malpighian) tubule is a classic example of branched tubular morphogenesis, allowing study of mesenchymal-to-epithelial transitions, stem cell-mediated regeneration, and the evolution of a glomerular kidney. Tubule function employs conserved transport proteins, such as the Na+, K+-ATPase and V-ATPase, aquaporins, inward rectifier K+ channels, and organic solute transporters, regulated by cAMP, cGMP, nitric oxide, and calcium. In addition to generation and selective reabsorption of primary urine, the tubule plays roles in metabolism and excretion of xenobiotics, and in innate immunity. The gene expression resource shows that the tubule is an ideal tissue for the modeling of renal diseases, such as nephrolithiasis and Bartter syndrome, or for inborn errors of metabolism. Studies are assisted by uniquely powerful genetic and transgenic resources, the widespread availability of mutant stocks, and low-cost, rapid deployment of new transgenics to allow manipulation of renal function in an organotypic context.

  5. Rapid Cycle Amine (RCA) 3.0 System Development (United States)

    Chullen, Cinda; Campbell, Colin; Papale, William; Hawes, Kevin; Wichowski, Robert


    The Rapid Cycle Amine (RCA) 3.0 system is currently under development by NASA, the Lyndon B. Johnson Space Center (JSC) in conjunction with United Technologies Corporation Aerospace Systems (UTAS). The RCA technology is a new carbon dioxide (CO2) and humidity removal system that has been baselined for the Advanced Extravehicular Mobility Unit (AEMU) Portable Life Support System. The evolution of the RCA development has progressed through several iterations of technology readiness levels including RCA 1.0, RCA 2.0, and RCA 3.0 test articles. The RCA is an advancement over currently technologies due to its unique regeneration capability. The RCA is capable of simultaneously removing CO2 and humidity from an influent air steam and subsequent regeneration when exposed to a vacuum source. The RCA technology uses two solid amine sorbent beds in an alternating fashion to adsorb CO2 and water (uptake mode) and desorb CO2 and water (regeneration mode) at the same time. The two beds operate in an efficient manner so that while one bed is in the uptake mode, the other is in the regeneration mode, thus continuously providing an on-service sorbent bed by which CO2 and humidity may be removed. The RCA 2.0 and 3.0 test articles were designed with a novel valve assembly which allows for switching between uptake and regeneration modes with only one moving part while minimizing gas volume losses to the vacuum source by means of an internal pressure equalization step during actuation. The RCA technology also is low power, small, and has performed extremely well in all development testing thus far. A final design was selected for the RCA 3.0, fabricated, assembled, and performance tested in 2014 with delivery to NASAJSC in January 2015. This paper will provide an overview on the RCA 3.0 system design and results of pre-delivery testing with references to the development of RCA 1.0 and RCA 2.0.

  7. Rapid Detection of Land Cover Changes Using Crowdsourced Geographic Information: A Case Study of Beijing, China

    Directory of Open Access Journals (Sweden)

    Yuan Meng


    Full Text Available Land cover change (LCC detection is a significant component of sustainability research including ecological economics and climate change. Due to the rapid variability of natural environment, effective LCC detection is required to capture sufficient change-related information. Although such information has been available through remotely sensed images, the complicated image processing and classification make it time consuming and labour intensive. In contrast, the freely available crowdsourced geographic information (CGI contains easily interpreted textual information, and thus has the potential to be applied for capturing effective change-related information. Therefore, this paper presents and evaluates a method using CGI for rapid LCC detection. As a case study, Beijing is chosen as the study area, and CGI is applied to monitor LCC information. As one kind of CGI which is generated from commercial Internet maps, points of interest (POIs with detailed textual information are utilised to detect land cover in 2016. Those POIs are first classified into land cover nomenclature based on their textual information. Then, a kernel density approach is proposed to effectively generate land cover regions in 2016. Finally, with GlobeLand30 in 2010 as baseline map, LCC is detected using the post-classification method in the period of 2010–2016 in Beijing. The result shows that an accuracy of 89.20% is achieved with land cover regions generated by POIs, indicating that POIs are reliable for rapid LCC detection. Additionally, an LCC detection comparison is proposed between remotely sensed images and CGI, revealing the advantages of POIs in terms of LCC efficiency. However, due to the uneven distribution, remotely sensed images are still required in areas with few POIs.

  8. A proteomic approach for the rapid, multi-informative and reliable identification of blood. (United States)

    Patel, E; Cicatiello, P; Deininger, L; Clench, M R; Marino, G; Giardina, P; Langenburg, G; West, A; Marshall, P; Sears, V; Francese, S


    Blood evidence is frequently encountered at the scene of violent crimes and can provide valuable intelligence in the forensic investigation of serious offences. Because many of the current enhancement methods used by crime scene investigators are presumptive, the visualisation of blood is not always reliable nor does it bear additional information. In the work presented here, two methods employing a shotgun bottom up proteomic approach for the detection of blood are reported; the developed protocols employ both an in solution digestion method and a recently proposed procedure involving immobilization of trypsin on hydrophobin Vmh2 coated MALDI sample plate. The methods are complementary as whilst one yields more identifiable proteins (as biomolecular signatures), the other is extremely rapid (5 minutes). Additionally, data demonstrate the opportunity to discriminate blood provenance even when two different blood sources are present in a mixture. This approach is also suitable for old bloodstains which had been previously chemically enhanced, as experiments conducted on a 9-year-old bloodstain deposited on a ceramic tile demonstrate.

  9. Rapid Integration of Tactile and Visual Information by a Newly Sighted Child. (United States)

    Chen, Jie; Wu, En-De; Chen, Xin; Zhu, Lu-He; Li, Xiaoman; Thorn, Frank; Ostrovsky, Yuri; Qu, Jia


    How we learn to interact with and understand our environment for the first time is an age-old philosophical question. Scientists have long sought to understand what is the origin of egocentric spatial localization and the perceptual integration of touch and visual information. It is difficult to study the beginnings of intermodal visual-motor and visual-tactile linkages in early infancy since infants' muscular strength and control cannot accurately guide visual-motor behavior and they do not concentrate well [1-6]. Alternatively, one can examine young children who have a restored congenital sensory modality loss. They are the best infant substitute if they are old enough for good muscle control and young enough to be within the classic critical period for neuroplasticity [7, 8]. Recovery studies after removal of dense congenital cataracts are examples of this, but most are performed on older subjects [9-14]. We report here the results of video-recorded experiments on a congenitally blind child, beginning immediately after surgical restoration of vision. Her remarkably rapid development of accurate reaching and grasping showed that egocentric spatial localization requires neural circuitry needing less than a half hour of spatially informative experience to be calibrated. 32 hr after first sight, she visually recognized an object that she had simultaneously looked at and held, even though she could not use single senses alone (vision to vision; touch to touch) to perform this recognition until the following day. Then she also performed intersensory transfer of tactile object experience to visual object recognition, demonstrating that the two senses are prearranged to immediately become calibrated to one another.

  10. Rapid and Reusable Text Visualization and Exploration Development with DELVE. (United States)

    Harris, Daniel R; Kavuluru, Ramakanth; Jaromczyk, Jerzy W; Johnson, Todd R


    We present DELVE (Document ExpLoration and Visualization Engine), a framework for developing interactive visualizations as modular Web-applications to assist researchers with exploratory literature search. The goal for web-applications driven by DELVE is to better satisfy the information needs of researchers and to help explore and understand the state of research in scientific liter ature by providing immersive visualizations that both contain facets and are driven by facets derived from the literature. We base our framework on principles from user-centered design and human-computer interaction (HCI). Preliminary evaluations demon strate the usefulness of DELVE's techniques: (1) a clinical researcher immediately saw that her original query was inappropriate simply due to the frequencies displayed via generalized clouds and (2) a muscle biologist quickly learned of vocabulary differences found between two disciplines that were referencing the same idea, which we feel is critical for interdisciplinary work. We dis cuss the underlying category-theoretic model of our framework and show that it naturally encourages the development of reusable visualizations by emphasizing interoperability.

  11. Using a Novel Spatial Tool to Inform Invasive Species Early Detection and Rapid Response Efforts (United States)

    Davidson, Alisha D.; Fusaro, Abigail J.; Kashian, Donna R.


    Management of invasive species has increasingly emphasized the importance of early detection and rapid response (EDRR) programs in limiting introductions, establishment, and impacts. These programs require an understanding of vector and species spatial dynamics to prioritize monitoring sites and efficiently allocate resources. Yet managers often lack the empirical data necessary to make these decisions. We developed an empirical mapping tool that can facilitate development of EDRR programs through identifying high-risk locations, particularly within the recreational boating vector. We demonstrated the utility of this tool in the Great Lakes watershed. We surveyed boaters to identify trips among water bodies and to quantify behaviors associated with high likelihood of species transfer (e.g., not removing organic materials from boat trailers) during that trip. We mapped water bodies with high-risk inbound and outbound boater movements using ArcGIS. We also tested for differences in high-risk behaviors based on demographic variables to understand risk differences among boater groups. Incorporation of boater behavior led to identification of additional high-risk water bodies compared to using the number of trips alone. Therefore, the number of trips itself may not fully reflect the likelihood of invasion. This tool can be broadly applied in other geographic contexts and with different taxa, and can be adjusted according to varying levels of information concerning the vector or species of interest. The methodology is straightforward and can be followed after a basic introduction to ArcGIS software. The visual nature of the mapping tool will facilitate site prioritization by managers and stakeholders from diverse backgrounds.

  17. Cochrane Rapid Reviews Methods Group to play a leading role in guiding the production of informed high-quality, timely research evidence syntheses

    Directory of Open Access Journals (Sweden)

    Chantelle Garritty


    Full Text Available Abstract Background Policymakers and healthcare stakeholders are increasingly seeking evidence to inform the policymaking process, and often use existing or commissioned systematic reviews to inform decisions. However, the methodologies that make systematic reviews authoritative take time, typically 1 to 2 years to complete. Outside the traditional SR timeline, “rapid reviews” have emerged as an efficient tool to get evidence to decision-makers more quickly. However, the use of rapid reviews does present challenges. To date, there has been limited published empirical information about this approach to compiling evidence. Thus, it remains a poorly understood and ill-defined set of diverse methodologies with various labels. In recent years, the need to further explore rapid review methods, characteristics, and their use has been recognized by a growing network of healthcare researchers, policymakers, and organizations, several with ties to Cochrane, which is recognized as representing an international gold standard for high-quality, systematic reviews. Purpose In this commentary, we introduce the newly established Cochrane Rapid Reviews Methods Group developed to play a leading role in guiding the production of rapid reviews given they are increasingly employed as a research synthesis tool to support timely evidence-informed decision-making. We discuss how the group was formed and outline the group’s structure and remit. We also discuss the need to establish a more robust evidence base for rapid reviews in the published literature, and the importance of promoting registration of rapid review protocols in an effort to promote efficiency and transparency in research. Conclusion As with standard systematic reviews, the core principles of evidence-based synthesis should apply to rapid reviews in order to minimize bias to the extent possible. The Cochrane Rapid Reviews Methods Group will serve to establish a network of rapid review stakeholders

  4. Information Systems Development as a Research Method

    Directory of Open Access Journals (Sweden)

    Helen Hasan


    Full Text Available This paper takes the stance that some cases of information systems development can be considered knowledge creating activities, and, in those cases, information systems development can be a legitimate research method. In these cases not only is knowledge created about the development process itself but also a deeper understanding emerges about the organisational problem that the system is designed to solve. The paper begins with a brief overview of research in the design sciences and a comparison of research methods that are concerned with the design, and use, of information systems. This is followed by an assessment of the way systems development as a research method deals with the scientific research processes of data collection, analysis, synthesis and display. A case study, where the systems development research method was use, is described to illustrate the method and give the reader a better understanding of the approach.

  6. Rapid and highly informative diagnostic assay for H5N1 influenza viruses.

    Directory of Open Access Journals (Sweden)

    Nader Pourmand

    Full Text Available A highly discriminative and information-rich diagnostic assay for H5N1 avian influenza would meet immediate patient care needs and provide valuable information for public health interventions, e.g., tracking of new and more dangerous variants by geographic area as well as avian-to-human or human-to-human transmission. In the present study, we have designed a rapid assay based on multilocus nucleic acid sequencing that focuses on the biologically significant regions of the H5N1 hemagglutinin gene. This allows the prediction of viral strain, clade, receptor binding properties, low- or high-pathogenicity cleavage site and glycosylation status. H5 HA genes were selected from nine known high-pathogenicity avian influenza subtype H5N1 viruses, based on their diversity in biologically significant regions of hemagglutinin and/or their ability to cause infection in humans. We devised a consensus pre-programmed pyrosequencing strategy, which may be used as a faster, more accurate alternative to de novo sequencing. The available data suggest that the assay described here is a reliable, rapid, information-rich and cost-effective approach for definitive diagnosis of H5N1 avian influenza. Knowledge of the predicted functional sequences of the HA will enhance H5N1 avian influenza surveillance efforts.

  7. Episodic Memory Retrieval Functionally Relies on Very Rapid Reactivation of Sensory Information. (United States)

    Waldhauser, Gerd T; Braun, Verena; Hanslmayr, Simon


    Episodic memory retrieval is assumed to rely on the rapid reactivation of sensory information that was present during encoding, a process termed "ecphory." We investigated the functional relevance of this scarcely understood process in two experiments in human participants. We presented stimuli to the left or right of fixation at encoding, followed by an episodic memory test with centrally presented retrieval cues. This allowed us to track the reactivation of lateralized sensory memory traces during retrieval. Successful episodic retrieval led to a very early (∼100-200 ms) reactivation of lateralized alpha/beta (10-25 Hz) electroencephalographic (EEG) power decreases in the visual cortex contralateral to the visual field at encoding. Applying rhythmic transcranial magnetic stimulation to interfere with early retrieval processing in the visual cortex led to decreased episodic memory performance specifically for items encoded in the visual field contralateral to the site of stimulation. These results demonstrate, for the first time, that episodic memory functionally relies on very rapid reactivation of sensory information. Remembering personal experiences requires a "mental time travel" to revisit sensory information perceived in the past. This process is typically described as a controlled, relatively slow process. However, by using electroencephalography to measure neural activity with a high time resolution, we show that such episodic retrieval entails a very rapid reactivation of sensory brain areas. Using transcranial magnetic stimulation to alter brain function during retrieval revealed that this early sensory reactivation is causally relevant for conscious remembering. These results give first neural evidence for a functional, preconscious component of episodic remembering. This provides new insight into the nature of human memory and may help in the understanding of psychiatric conditions that involve the automatic intrusion of unwanted memories. Copyright

  11. Development of the stock exchange information system

    Directory of Open Access Journals (Sweden)

    Miladinović Radojko


    Full Text Available The stock exchange represents the key institution for the development of capital market of any country. Thus the information system of every stock exchange must satisfy very strict international standards. The development of these systems is particularly difficult in countries in transition, due to intense economic and legal changes, lack of technical and financial resources, lack of experience and knowledge in the area of the capital market business, etc. Therefore the special software project management methodology for their realization must be clearly defined. In the development process of the Belgrade Stock Exchange (BSE information system a new software project management methodology for its realization has been defined, the application of which is illustrated through a series of different development stages of the Belgrade Stock Exchange information system. In order to make all the problems more comprehensive, only the continuous trading method is described, being the most frequently used trading method in the world.

  12. Developing a Rapid Algorithm to Enable Rapid Characterization of Alginate Microcapsules. (United States)

    Chan, Ka Hei; Krishnan, Rahul; Alexander, Michael; Lakey, Jonathan R T


    The islets of Langerhans are endocrine tissue clusters that secrete hormones that regulate the body's glucose, carbohydrate, and fat metabolism, the most important of which is insulin, a hormone secreted by β-cells within the islets. In certain instances, a person's own immune system attacks and destroys them, leading to the development of type 1 diabetes (T1D), a life-long condition that needs daily insulin administration to maintain health and prolong survival. Islet transplantation is a surgical procedure that has demonstrated the ability to normalize blood sugar levels for up to a few years, but the need for chronic immunosuppression relegates it to a last resort that is often only used sparingly and in seriously ill patients. Islet microencapsulation is a biomedical innovation designed to protect islets from the immune system by coating them with a biocompatible polymer, and this new technology has demonstrated various degrees of success in small- and large-animal studies. This success is significantly impacted by microcapsule morphology and encapsulation efficiency. Since hundreds of thousands of microcapsules are generated during the process, characterization of encapsulated islets without the help of some degree of automation would be difficult, time-consuming, and error prone due to inherent observer bias. We have developed an image analysis algorithm that can analyze hundreds of microencapsulated islets and characterize their size, shape, circularity, and distortion with minimal observer bias. This algorithm can be easily adapted to similar nano- or microencapsulation technologies to implement stricter quality control and improve biomaterial device design and success.

  14. Talisman--rapid application development for the grid. (United States)

    Oinn, Thomas M


    In order to make use of the emerging grid and network services offered by various institutes and mandated by many current research projects, some kind of user accessible client is required. In contrast with attempts to build generic workbenches, Talisman is designed to allow a bioinformatics expert to rapidly build custom applications, immediately visible using standard web technology, for users who wish to concentrate on the biology of their problem rather than the informatics aspects. As a component of the MyGrid project, it is intended to allow access to arbitrary resources, including but not limited to relational, object and flat file data sources, analysis programs and grid based storage, tracking and distributed annotation systems.

  15. The Development of Rapidly Solidified Magnesium – Copper Ribbons

    Directory of Open Access Journals (Sweden)

    Pastuszak M.


    Full Text Available The aim of the present work was to plan and carry out an experiment consisting of amorphization of industrial magnesium alloy WE 43 (Mg - 4 Y - 3 RE - 0.5 Zr modified by the copper addition. Investigated alloy modified with 20% of copper was rapidly quenched with the use of melt spinning technique. The effects of cooling rate on the structure and properties of the obtained material were extensively analyzed. The structure and phase analysis of samples were examined using X-ray diffraction method (XRD while the thermal stability of the samples was determined by differential scanning calorimetry (DSC. Microstructure observations were also conducted. The microhardness tests (HV0.02 and corrosion resistance tests were carried out to investigate the properties of the material. Corrosion resistance measurements were held using a typical three-electrode system. As the result of the research, the effect of cooling rate on microstructure and properties of investigated alloy was determined.

  16. The electric and magnetic fields research and public information dissemination (EMF-RAPID) program. (United States)

    Moulder, J E


    In the United States, public concern that exposure to power-line fields was linked to cancer led to the establishment of a Congressionally mandated program, the Electric and Magnetic Fields Research and Public Information Dissemination (EMF-RAPID) Program. A major goal of the program was to "determine whether or not exposures to electric and magnetic fields produced by the generation, transmission, and use of electrical energy affect human health". Between 1994 and 1998, the EMF-RAPID program spent approximately $41 million on biological research. Much of the work funded by the EMF-RAPID program has not yet been published in the peer-reviewed literature. The U.S. National Institute of Environmental Health Sciences (NIEHS) asked that Radiation Research publish this special issue in an attempt to remedy this publication gap. The issue includes reviews of studies that were done to assess the biological plausibility of claims that power-frequency fields caused leukemia and breast cancer. The issue continues with two teratology studies and one immunology study. The section of the issue covering in vitro studies begins with an overview of the efforts NIEHS made to replicate a wide range of reported effects of power-frequency fields and continues with four papers reporting the absence of effects of power-frequency fields on the expression of stress-response genes and oncogenes. Other reports of in vitro studies and studies of mechanisms cover cytotoxicity, gap junction intracellular communication, calcium ion transport across the plasma membrane, and intracellular electric fields.

  20. Incorporating rapid neocortical learning of new schema-consistent information into complementary learning systems theory. (United States)

    McClelland, James L


    The complementary learning systems theory of the roles of hippocampus and neocortex (McClelland, McNaughton, & O'Reilly, 1995) holds that the rapid integration of arbitrary new information into neocortical structures is avoided to prevent catastrophic interference with structured knowledge representations stored in synaptic connections among neocortical neurons. Recent studies (Tse et al., 2007, 2011) showed that neocortical circuits can rapidly acquire new associations that are consistent with prior knowledge. The findings challenge the complementary learning systems theory as previously presented. However, new simulations extending those reported in McClelland et al. (1995) show that new information that is consistent with knowledge previously acquired by a putatively cortexlike artificial neural network can be learned rapidly and without interfering with existing knowledge; it is when inconsistent new knowledge is acquired quickly that catastrophic interference ensues. Several important features of the findings of Tse et al. (2007, 2011) are captured in these simulations, indicating that the neural network model used in McClelland et al. has characteristics in common with neocortical learning mechanisms. An additional simulation generalizes beyond the network model previously used, showing how the rate of change of cortical connections can depend on prior knowledge in an arguably more biologically plausible network architecture. In sum, the findings of Tse et al. are fully consistent with the idea that hippocampus and neocortex are complementary learning systems. Taken together, these findings and the simulations reported here advance our knowledge by bringing out the role of consistency of new experience with existing knowledge and demonstrating that the rate of change of connections in real and artificial neural networks can be strongly prior-knowledge dependent.

  1. Development of Information Technology for Smart Defense

    Energy Technology Data Exchange (ETDEWEB)

    Chung, Kyoil; Lee, So Yeon; Park, Sangjoon; Park, Jonghyun [ETRI, Daejeon (Korea, Republic of); Han, Sangcheol [KEIT, Seoul (Korea, Republic of)


    Recently, there has been demand for the convergence of IT (Information and communication Technologies, ICT) with defense, as has already been achieved in civilian fields such as healthcare and construction. It is expected that completely new and common requirements would emerge from the civilian and military domains and that the shape of war field would change rapidly. Many military scientists forecast that future wars would be network-centric and be based on C4I(Command, Control, Communication and Computer, Intelligence), ISR(Intelligence, Surveillance and Reconnaissance), and PGM(Precision Guided Munitions). For realizing the smart defense concept, IT should act as a baseline technology even for simulating a real combat field using virtual reality. In this paper, we propose the concept of IT-based smart defense with a focus on accurate detection in real and cyber wars, effective data communication, automated and unmanned operation, and modeling and simulation.

    Full Text Available A new approach has been proposed for rapid and easy evaluation of a indicator of quality and properties of natural water - soluble salt content (mineralization. The method of quartz crystal microbalance is employed at load of the mass-sensitive resonator electrode (BAW-type with investigated water. The degree of correlation between the various indicators related to the contents of salts and insoluble compounds and the level of mineralization obtained by the standard method (gravimetry has been studied. A procedure for salt weighing by single sensor at unilateral load with small sample of natural water has been developed. The optimal conditions for measurement is established using the design of experiment by model 23 . The possibilities of quartz crystal microbalance for determination of non-volatile compounds in the water are described. The calibration of piezosensor is produced by standard solution NaCl (c = 1.000 g / dm3 at optimal conditions of experiment. The adequacy and accuracy of proposed technique is assessed by the correlation between the results of quartz crystal microbalance and conductometry. The correlation between indicators of mineralization established by quartz crystal microbalance and gravimetry is found. It has been obtained an equation that can be used to calculate the standard indicator of the mineralization by the results of a quartz crystal microbalance using single sensor. The approaches to enhance the analytical capabilities of the developed technique for water with low and high mineralization are proposed. The metrological characteristics of quartz crystal microbalance of insoluble compounds in natural water are estimated. A new technique of determination of the mass concentration of the dry residue in water with a conductivity of 0.2 mS or above has been developed, which can be used for rapid analysis of the water at nonlaboratory conditions and in the laboratory for rapid obtaining the information about a sample.

  7. Motivation and challenges for use of malaria rapid diagnostic tests among informal providers in Myanmar: a qualitative study. (United States)

    Sudhinaraset, May; Briegleb, Christina; Aung, Moe; Khin, Hnin Su Su; Aung, Tin


    Rapid diagnostic tests (RDTs) for malaria enable proper diagnosis and have been shown to reduce overuse of artemisinin combination therapy. Few studies have evaluated the feasibility and use of RDTs in the private sector in Myanmar. The objectives of the study were to: 1) understand the acceptability of using RDTs in the informal sector in Myanmar; 2) examine motivations for use among informal providers; and, 3) highlight decision-making and knowledge of providers for diagnostic testing and treatment. Qualitative interviews were conducted with 30 informal providers. Purposeful sampling was used to enrol study participants in the Mon and Shan State in Myanmar. All interviews were conducted in Burmese, translated into English, and two researchers coded all interviews using Atlas ti. Major themes identified included: 1) informal provider and outlet characteristics, including demographic and background characteristics; 2) the benefits and challenges of using RDTs according to providers; 3) provider experiences with using RDTs, including motivations for using the RDT; 4) adherence to test results, either positive or negative; and, 5) recommendations from informal providers to promote increased use of RDTs in their communities. This study found that introducing RDTs to informal providers in Myanmar was feasible, resulting in improved provider empowerment and patient-provider relationships. Specific challenges included facility infrastructure to use and dispose RDTs and provider knowledge. This varied across the type of informal provider, with itinerant drug vendors more comfortable and knowledgeable about RDTs compared to general retail sellers and medical drug representatives. This study found informal providers in Myanmar found the introduction of RDTs to be highly acceptable. Providers discussed improvement in service quality including provider empowerment and patient-provider relationships. The study also highlighted a number of challenges that informal providers

  10. How citizen seismology is transforming rapid public earthquake information and interactions between seismologists and society (United States)

    Bossu, Rémy; Steed, Robert; Mazet-Roux, Gilles; Roussel, Fréderic; Caroline, Etivant


    Historical earthquakes are only known to us through written recollections and so seismologists have a long experience of interpreting the reports of eyewitnesses, explaining probably why seismology has been a pioneer in crowdsourcing and citizen science. Today, Internet has been transforming this situation; It can be considered as the digital nervous system comprising of digital veins and intertwined sensors that capture the pulse of our planet in near real-time. How can both seismology and public could benefit from this new monitoring system? This paper will present the strategy implemented at Euro-Mediterranean Seismological Centre (EMSC) to leverage this new nervous system to detect and diagnose the impact of earthquakes within minutes rather than hours and how it transformed information systems and interactions with the public. We will show how social network monitoring and flashcrowds (massive website traffic increases on EMSC website) are used to automatically detect felt earthquakes before seismic detections, how damaged areas can me mapped through concomitant loss of Internet sessions (visitors being disconnected) and the benefit of collecting felt reports and geolocated pictures to further constrain rapid impact assessment of global earthquakes. We will also describe how public expectations within tens of seconds of ground shaking are at the basis of improved diversified information tools which integrate this user generated contents. A special attention will be given to LastQuake, the most complex and sophisticated Twitter QuakeBot, smartphone application and browser add-on, which deals with the only earthquakes that matter for the public: the felt and damaging earthquakes. In conclusion we will demonstrate that eyewitnesses are today real time earthquake sensors and active actors of rapid earthquake information.

  11. Information as a Manifestation of Development

    Directory of Open Access Journals (Sweden)

    James A. Coffman


    Full Text Available Information manifests a reduction in uncertainty or indeterminacy. As such it can emerge in two ways: by measurement, which involves the intentional choices of an observer; or more generally, by development, which involves systemically mutual (‘self-organizing’ processes that break symmetry. The developmental emergence of information is most obvious in ontogeny, but pertains as well to the evolution of ecosystems and abiotic dissipative structures. In this review, a seminal, well-characterized ontogenetic paradigm—the sea urchin embryo—is used to show how cybernetic causality engenders the developmental emergence of biological information at multiple hierarchical levels of organization. The relevance of information theory to developmental genomics is also discussed.

  20. Development of a Rapid Salivary Proteomic Platform for Oral Feeding Readiness in the Preterm Newborn

    Directory of Open Access Journals (Sweden)

    Prarthana Khanna


    Full Text Available Oral feeding competency is a major determinant of length of stay in the neonatal intensive care unit. An infant must be able to consistently demonstrate the ability to take all required enteral nutrition by mouth before discharge home. Most infants born prematurely (<37 weeks will require days, if not weeks, to master this oral feeding competency skill. Inappropriately timed feeding attempts can lead to acute and long-term morbidities, prolonged hospitalizations, and increased health-care costs. Previously, a panel of five genes involved in essential developmental pathways including sensory integration (nephronophthisis 4, Plexin A1, hunger signaling [neuropeptide Y2 receptor (NPY2R, adenosine-monophosphate-activated protein kinase (AMPK], and facial development (wingless-type MMTV integration site family, member 3 required for oral feeding success were identified in neonatal saliva. This study aimed to translate these five transcriptomic biomarkers into a rapid proteomic platform to provide objective, real-time assessment of oral feeding skills, to better inform care, and to improve neonatal outcomes. Total protein was extracted from saliva of 10 feeding-successful and 10 feeding-unsuccessful infants matched for age, sex, and post-conceptional age. Development of immunoassays was attempted for five oral feeding biomarkers and two reference biomarkers (GAPDH and YWHAZ to normalize for starting protein concentrations. Normalized protein concentrations were correlated to both feeding status at time of sample collection and previously described gene expression profiles. Only the reference proteins and those involved in hunger signaling were detected in neonatal saliva at measurable levels. Expression patterns for NPY2R and AMPK correlated with the gene expression patterns previously seen between successful and unsuccessful feeders and predicted feeding outcome. Salivary proteins associated with hunger signaling are readily quantifiable in

  5. Twitter as Information Source for Rapid Damage Estimation after Major Earthquakes (United States)

    Eggert, Silke; Fohringer, Joachim


    Natural disasters like earthquakes require a fast response from local authorities. Well trained rescue teams have to be available, equipment and technology has to be ready set up, information have to be directed to the right positions so the head quarter can manage the operation precisely. The main goal is to reach the most affected areas in a minimum of time. But even with the best preparation for these cases, there will always be the uncertainty of what really happened in the affected area. Modern geophysical sensor networks provide high quality data. These measurements, however, are only mapping disjoint values from their respective locations for a limited amount of parameters. Using observations of witnesses represents one approach to enhance measured values from sensors ("humans as sensors"). These observations are increasingly disseminated via social media platforms. These "social sensors" offer several advantages over common sensors, e.g. high mobility, high versatility of captured parameters as well as rapid distribution of information. Moreover, the amount of data offered by social media platforms is quite extensive. We analyze messages distributed via Twitter after major earthquakes to get rapid information on what eye-witnesses report from the epicentral area. We use this information to (a) quickly learn about damage and losses to support fast disaster response and to (b) densify geophysical networks in areas where there is sparse information to gain a more detailed insight on felt intensities. We present a case study from the Mw 7.1 Philippines (Bohol) earthquake that happened on Oct. 15 2013. We extract Twitter messages, so called tweets containing one or more specified keywords from the semantic field of "earthquake" and use them for further analysis. For the time frame of Oct. 15 to Oct 18 we get a data base of in total 50.000 tweets whereof 2900 tweets are geo-localized and 470 have a photo attached. Analyses for both national level and locally for

  8. From Information Management to Information Visualization: Development of Radiology Dashboards. (United States)

    Karami, Mahtab; Safdari, Reza


    The development and implementation of a dashboard of medical imaging department (MID) performance indicators. Several articles discussing performance measures of imaging departments were searched for this study. All the related measures were extracted. Then, a panel of imaging experts were asked to rate these measures with an open ended question to seek further potential indicators. A second round was performed to confirm the performance rating. The indicators and their ratings were then reviewed by an executive panel. Based on the final panel's rating, a list of indicators to be used was developed. A team of information technology consultants were asked to determine a set of user interface requirements for the building of the dashboard. In the first round, based on the panel's rating, a list of main features or requirements to be used was determined. Next, Qlikview was utilized to implement the dashboard to visualize a set of selected KPI metrics. Finally, an evaluation of the dashboard was performed. 92 MID indicators were identified. On top of this, 53 main user interface requirements to build of the prototype of dashboard were determined. Then, the project team successfully implemented a prototype of radiology management dashboards into study site. The visual display that was designed was rated highly by users. To develop a dashboard, management of information is essential. It is recommended that a quality map be designed for the MID. It can be used to specify the sequence of activities, their related indicators and required data for calculating these indicators. To achieve both an effective dashboard and a comprehensive view of operations, it is necessary to design a data warehouse for gathering data from a variety of systems. Utilizing interoperability standards for exchanging data among different systems can be also effective in this regard.

  9. Lymphatic transport of exosomes as a rapid route of information dissemination to the lymph node. (United States)

    Srinivasan, Swetha; Vannberg, Fredrik O; Dixon, J Brandon


    It is well documented that cells secrete exosomes, which can transfer biomolecules that impact recipient cells' functionality in a variety of physiologic and disease processes. The role of lymphatic drainage and transport of exosomes is as yet unknown, although the lymphatics play critical roles in immunity and exosomes are in the ideal size-range for lymphatic transport. Through in vivo near-infrared (NIR) imaging we have shown that exosomes are rapidly transported within minutes from the periphery to the lymph node by lymphatics. Using an in vitro model of lymphatic uptake, we have shown that lymphatic endothelial cells actively enhanced lymphatic uptake and transport of exosomes to the luminal side of the vessel. Furthermore, we have demonstrated a differential distribution of exosomes in the draining lymph nodes that is dependent on the lymphatic flow. Lastly, through endpoint analysis of cellular distribution of exosomes in the node, we identified macrophages and B-cells as key players in exosome uptake. Together these results suggest that exosome transfer by lymphatic flow from the periphery to the lymph node could provide a mechanism for rapid exchange of infection-specific information that precedes the arrival of migrating cells, thus priming the node for a more effective immune response.

  10. Infrastructure for Rapid Development of Java GUI Programs (United States)

    Jones, Jeremy; Hostetter, Carl F.; Wheeler, Philip


    The Java Application Shell (JAS) is a software framework that accelerates the development of Java graphical-user-interface (GUI) application programs by enabling the reuse of common, proven GUI elements, as distinguished from writing custom code for GUI elements. JAS is a software infrastructure upon which Java interactive application programs and graphical user interfaces (GUIs) for those programs can be built as sets of plug-ins. JAS provides an application- programming interface that is extensible by application-specific plugins that describe and encapsulate both specifications of a GUI and application-specific functionality tied to the specified GUI elements. The desired GUI elements are specified in Extensible Markup Language (XML) descriptions instead of in compiled code. JAS reads and interprets these descriptions, then creates and configures a corresponding GUI from a standard set of generic, reusable GUI elements. These elements are then attached (again, according to the XML descriptions) to application-specific compiled code and scripts. An application program constructed by use of JAS as its core can be extended by writing new plug-ins and replacing existing plug-ins. Thus, JAS solves many problems that Java programmers generally solve anew for each project, thereby reducing development and testing time.

  12. Integrating Low-Cost Rapid Usability Testing into Agile System Development of Healthcare IT: A Methodological Perspective. (United States)

    Kushniruk, Andre W; Borycki, Elizabeth M


    The development of more usable and effective healthcare information systems has become a critical issue. In the software industry methodologies such as agile and iterative development processes have emerged to lead to more effective and usable systems. These approaches highlight focusing on user needs and promoting iterative and flexible development practices. Evaluation and testing of iterative agile development cycles is considered an important part of the agile methodology and iterative processes for system design and re-design. However, the issue of how to effectively integrate usability testing methods into rapid and flexible agile design cycles has remained to be fully explored. In this paper we describe our application of an approach known as low-cost rapid usability testing as it has been applied within agile system development in healthcare. The advantages of the integrative approach are described, along with current methodological considerations.

  13. Development of information technology: Ethical dimensions

    Directory of Open Access Journals (Sweden)

    Pećanac Slobodan


    Full Text Available Despite disagreements about whether the technology development in general (including information technology is something that is good or bad for the morale of the community and the individual, there is no dispute that this influence exists. Even when negatively affecting morale, these technologies do so only in the presence of other essential factors primarly and above all human intentions that go beyond the moral norms. So, no matter how much we are certain that information technologies themselves are not the main factor of immorality that does not mean that their use that leads to the 'chaos of immorality' should not be prevented. First of all, by strengthening of the moral community. In any case, mankind can not afford the luxury of hesitating when considering ethical questions posed to the fast development of technology and information transfer despite the pressures to shift all responsibility on lawyers and politicians. Certain legislation within the communities is inevitable and no doubt necessary, but solving ethical dilemmas in the field of new media should be left to the moral community and the reasonable judgment of all its members and not the exclusive regulatory powers of government. Defence of the communication ethics through new media is conditioned by the previously achieved results of efforts to defend the basic principles of sociability. Therefore, conscious efforts for establishing a much stronger social moral legally must lead to a reduction of moral chaos in all areas of communication and means of communication and new information technologies.

  14. Rapid identification of paragonimiasis foci by lay informants in Lao People's Democratic Republic.

    Directory of Open Access Journals (Sweden)

    Peter Odermatt

    Full Text Available BACKGROUND: Paragonimiasis is a food-borne trematodiasis leading to lung disease. Worldwide, an estimated 21 million people are infected. Foci of ongoing transmission remain often unnoticed. We evaluated a simple questionnaire approach using lay-informants at the village level to identify paragonimiasis foci and suspected paragonimiasis cases. METHODOLOGY/PRINCIPAL FINDINGS: The study was carried out in an endemic area of Lao People's Democratic Republic. Leaders of 49 remote villages in northern Vientiane Province were asked to notify suspected paragonimiasis patients using a four-item questionnaire sent through administrative channels: persons responding positively for having chronic cough (more than 3 weeks and/or blood in sputum with or without fever. We validated the village leaders' reports in ten representative villages with a door-to-door survey. We examined three sputa of suspected patients for the presence of Paragonimus eggs and acid fast bacilli. 91.8% of village leaders participated and notified a total of 220 suspected patients; 76.2% were eventually confirmed; an additional 138 suspected cases were found in the survey. Sensitivity of village leaders' notice for "chronic cough" and "blood in sputum" was 100%; "blood in sputum" alone reached a sensitivity of 85.7%. SIGNIFICANCE: Our approach led to the identification of three previously unknown foci of transmission. A rapid and simple lay-informant questionnaire approach is a promising low-cost community diagnostic tool of paragonimiasis control programs.

  15. Parallel grid library for rapid and flexible simulation development (United States)

    Honkonen, I.; von Alfthan, S.; Sandroos, A.; Janhunen, P.; Palmroth, M.


    We present an easy to use and flexible grid library for developing highly scalable parallel simulations. The distributed cartesian cell-refinable grid (dccrg) supports adaptive mesh refinement and allows an arbitrary C++ class to be used as cell data. The amount of data in grid cells can vary both in space and time allowing dccrg to be used in very different types of simulations, for example in fluid and particle codes. Dccrg transfers the data between neighboring cells on different processes transparently and asynchronously allowing one to overlap computation and communication. This enables excellent scalability at least up to 32 k cores in magnetohydrodynamic tests depending on the problem and hardware. In the version of dccrg presented here part of the mesh metadata is replicated between MPI processes reducing the scalability of adaptive mesh refinement (AMR) to between 200 and 600 processes. Dccrg is free software that anyone can use, study and modify and is available at Users are also kindly requested to cite this work when publishing results obtained with dccrg.

  18. Geographic Information Systems and Web Page Development (United States)

    Reynolds, Justin


    The Facilities Engineering and Architectural Branch is responsible for the design and maintenance of buildings, laboratories, and civil structures. In order to improve efficiency and quality, the FEAB has dedicated itself to establishing a data infrastructure based on Geographic Information Systems, GIs. The value of GIS was explained in an article dating back to 1980 entitled "Need for a Multipurpose Cadastre which stated, "There is a critical need for a better land-information system in the United States to improve land-conveyance procedures, furnish a basis for equitable taxation, and provide much-needed information for resource management and environmental planning." Scientists and engineers both point to GIS as the solution. What is GIS? According to most text books, Geographic Information Systems is a class of software that stores, manages, and analyzes mapable features on, above, or below the surface of the earth. GIS software is basically database management software to the management of spatial data and information. Simply put, Geographic Information Systems manage, analyze, chart, graph, and map spatial information. At the outset, I was given goals and expectations from my branch and from my mentor with regards to the further implementation of GIs. Those goals are as follows: (1) Continue the development of GIS for the underground structures. (2) Extract and export annotated data from AutoCAD drawing files and construct a database (to serve as a prototype for future work). (3) Examine existing underground record drawings to determine existing and non-existing underground tanks. Once this data was collected and analyzed, I set out on the task of creating a user-friendly database that could be assessed by all members of the branch. It was important that the database be built using programs that most employees already possess, ruling out most AutoCAD-based viewers. Therefore, I set out to create an Access database that translated onto the web using Internet

  19. On Using Materiality in Information Systems Development

    DEFF Research Database (Denmark)

    Carugati, Andrea

    This research brief presents a discussion on the use of the concept of materiality and material knowing in information systems development (ISD). The discussion addresses some of the practical problems still plaguing ISD, augmenting existing ISD methodologies with contributions from systems theory...... and in particular the idea of inquiring systems. The discussion builds on different contemporary concepts that are rooted in the inquiring systems idea: the notion of stakeholders (designer, client, user and their interchanging roles), the notion boundary object and boundary spanners, and the notion of materiality...... as scaffold of knowledge. Through the example taken from a case study of a complex and innovative systems development we outline two design principles to be embedded in modular fashion in ISD processes: (1) whenever possible start ISD efforts by developing a graphical simulator of the material environment...

  20. Information technology for health in developing countries. (United States)

    Bukachi, Frederick; Pakenham-Walsh, Neil


    Poverty has deepened the crisis in health-care delivery in developing countries, particularly sub-Saharan Africa, which is a region facing a disease burden that is unmatched in the world. Whether access to proven and powerful information and communication technologies (ICTs) can improve health indicators is an ongoing debate. However, this brief review shows that in the last decade there has been significant growth in Internet access in urban areas; health-care workers now use it for communication, access to relevant health-care information, and international collaboration. The central message learned during this period about the application of ICTs is that infrastructural and cultural contexts vary and require different models and approaches. Thus, to harness the full potential of ICTs to the benefit of health systems, health workers, and patients will demand an intricate mix of old and new technologies.

  10. A data oriented framework for developing flexible information systems

    Directory of Open Access Journals (Sweden)

    František Dařena


    Full Text Available As a consequence of a rapidly changing environment, the success of organizations is dependent upon the ongoing and immediate adjustments of their information systems as reactions to these changes. Therefore, flexibility becomes one of the most crucial features in information systems. This paper specifies a data model oriented framework for the development of flexible information systems. The result of such process is a system that is sufficiently general and flexible in relation to solving problems related to changing environment. From general requirements related to data layer of information systems the paper discusses the definition of major elements of logical data model (entities and their hierarchical arrangement, attributes of the entities and their important characteristics, relationships among entities and their characteristics as well as possibilities of implementation and definition of application logic and data presentation. Proposed framework enables the organization to specify its own database structure, which best matches the situation of the organization and its environment. Because an approach similar to meta-data approaches is applied, methods for information sharing and interchange can be easily specified as well as program logic for manipulation with the data base on the application layer and data presentation.

  11. Lncident: A Tool for Rapid Identification of Long Noncoding RNAs Utilizing Sequence Intrinsic Composition and Open Reading Frame Information

    Directory of Open Access Journals (Sweden)

    Siyu Han


    Full Text Available More and more studies have demonstrated that long noncoding RNAs (lncRNAs play critical roles in diversity of biological process and are also associated with various types of disease. How to rapidly identify lncRNAs and messenger RNA is the fundamental step to uncover the function of lncRNAs identification. Here, we present a novel method for rapid identification of lncRNAs utilizing sequence intrinsic composition features and open reading frame information based on support vector machine model, named as Lncident (LncRNAs identification. The 10-fold cross-validation and ROC curve are used to evaluate the performance of Lncident. The main advantage of Lncident is high speed without the loss of accuracy. Compared with the exiting popular tools, Lncident outperforms Coding-Potential Calculator, Coding-Potential Assessment Tool, Coding-Noncoding Index, and PLEK. Lncident is also much faster than Coding-Potential Calculator and Coding-Noncoding Index. Lncident presents an outstanding performance on microorganism, which offers a great application prospect to the analysis of microorganism. In addition, Lncident can be trained by users’ own collected data. Furthermore, R package and web server are simultaneously developed in order to maximize the convenience for the users. The R package “Lncident” can be easily installed on multiple operating system platforms, as long as R is supported.

  13. Continuing Professional Development Evaluation: Two Rapid Review Courses inNephrology and Rheumatology

    Directory of Open Access Journals (Sweden)

    Abdullah Shehab


    Full Text Available Objectives: Continuing professional development (CPD is anovel approach to increase professional knowledge and skills. The aim of this study is to explore participants’ characteristics and to understand participants’ views on two rapid review courses (RRCs as part of CPD program, and to assess healthcare providers’ views about the use of internet for accessing medical information.Methods: Data were collected from 150 participants who attended an RRC in Nephrology and Rheumatology as part of an ongoing CME program.Results: Participants’ response rate was 92% and 84.4% in Nephrology and Rheumatology RRCs, respectively. Participants’ Mean Age±SD were 39±2.1 and 41±2.1 years in the Nephrology and Rheumatology courses, respectively. Demographic variables, i.e., age, gender, and specialization showed a significant (p<0.01 impact on the learning objectives of the program. Further, participants reported that the course material had a significant (p<0.02 impacton their knowledge. Finding new medical information was the primary motive to search the internet among all participants. About half of the subjects reported knowledge of their preferred medical education sites and had access at their clinical setup. Barriers to internet use included lack of specific information, difficulty to download contents, and excessive material. Professional association websites, online journals, and CME programs were the most frequently searched sources of information. Most of the subjects reported significant (p<0.02 barriers to find medical resources on the internet and to adequately utilize the currently available medical search engines available in the healthcare system.Conclusion: A discipline specific and integrated CPD programmay have provided dual benefit such as accredited CME hours and a significant change in the participants’ knowledge. There is a need to increase Internet accessibility and capacity in the current healthcare facilities. Future CPD

  14. EUnetHTA information management system: development and lessons learned. (United States)

    Chalon, Patrice X; Kraemer, Peter


    The aim of this study was to describe the techniques used in achieving consensus on common standards to be implemented in the EUnetHTA Information Management System (IMS); and to describe how interoperability between tools was explored. Three face to face meetings were organized to identify and agree on common standards to the development of online tools. Two tools were created to demonstrate the added value of implementing interoperability standards at local levels. Developers of tools outside EUnetHTA were identified and contacted. Four common standards have been agreed on by consensus; and consequently all EUnetHTA tools have been modified or designed accordingly. RDF Site Summary (RSS) has demonstrated a good potential to support rapid dissemination of HTA information. Contacts outside EUnetHTA resulted in direct collaboration (HTA glossary, HTAi Vortal), evaluation of options for interoperability between tools (CRD HTA database) or a formal framework to prepare cooperation on concrete projects (INAHTA projects database). While being entitled a project on IT infrastructure, the work program was also about people. When having to agree on complex topics, fostering a cohesive group dynamic and hosting face to face meetings brings added value and enhances understanding between partners. The adoption of widespread standards enhanced the homogeneity of the EUnetHTA tools and should thus contribute to their wider use, therefore, to the general objective of EUnetHTA. The initiatives on interoperability of systems need to be developed further to support a general interoperable information system that could benefit the whole HTA community.

  15. Transcranial Random Noise Stimulation (tRNS Shapes the Processing of Rapidly Changing Auditory Information

    Directory of Open Access Journals (Sweden)

    Katharina S. Rufener


    Full Text Available Neural oscillations in the gamma range are the dominant rhythmic activation pattern in the human auditory cortex. These gamma oscillations are functionally relevant for the processing of rapidly changing acoustic information in both speech and non-speech sounds. Accordingly, there is a tight link between the temporal resolution ability of the auditory system and inherent neural gamma oscillations. Transcranial random noise stimulation (tRNS has been demonstrated to specifically increase gamma oscillation in the human auditory cortex. However, neither the physiological mechanisms of tRNS nor the behavioral consequences of this intervention are completely understood. In the present study we stimulated the human auditory cortex bilaterally with tRNS while EEG was continuously measured. Modulations in the participants’ temporal and spectral resolution ability were investigated by means of a gap detection task and a pitch discrimination task. Compared to sham, auditory tRNS increased the detection rate for near-threshold stimuli in the temporal domain only, while no such effect was present for the discrimination of spectral features. Behavioral findings were paralleled by reduced peak latencies of the P50 and N1 component of the auditory event-related potentials (ERP indicating an impact on early sensory processing. The facilitating effect of tRNS was limited to the processing of near-threshold stimuli while stimuli clearly below and above the individual perception threshold were not affected by tRNS. This non-linear relationship between the signal-to-noise level of the presented stimuli and the effect of stimulation further qualifies stochastic resonance (SR as the underlying mechanism of tRNS on auditory processing. Our results demonstrate a tRNS related improvement in acoustic perception of time critical auditory information and, thus, provide further indices that auditory tRNS can amplify the resonance frequency of the auditory system.

  17. The rapid use of gender information: evidence of the time course of pronoun resolution from eyetracking. (United States)

    Arnold, J E; Eisenband, J G; Brown-Schmidt, S; Trueswell, J C


    Eye movements of listeners were monitored to investigate how gender information and accessibility influence the initial processes of pronoun interpretation. Previous studies on this issue have produced mixed results, and several studies have concluded that gender cues are not automatically used during the early processes of pronoun interpretation (e.g. Garnham, A., Oakhill, J. & Cruttenden, H. (1992). The role of implicit causality and gender cue in the interpretation of pronouns. Language and Cognitive Processes, 73 (4), 231-255; Greene, S. B., McKoon, G. & Ratcliff, R. (1992). Pronoun resolution and discourse models. Journal of Experimental Psychology: Learning, Memory, and Cognition, 182, 266-283). In the two experiments presented here, participants viewed a picture with two familiar cartoon characters of either same or different gender. They listened to a text describing the picture, in which a pronoun referred to either the first, more accessible, character, or the second. (For example, Donald is bringing some mail to ¿Mickey/Minnie¿ while a violent storm is beginning. He's carrying an umbrellaellipsis.) The results of both experiments show rapid use of both gender and accessibility at approximately 200 ms after the pronoun offset.

  19. Rapid culture-based diagnosis of pulmonary tuberculosis in developed and developing countries

    Directory of Open Access Journals (Sweden)

    Michel eDRANCOURT


    Full Text Available Culturing Mycobacterium tuberculosis remains the gold standard for the laboratory diagnosis of pulmonary tuberculosis, with 9 million new cases and 1.5 million deaths mainly in developing countries. Reviewing data reported over 20 years yields a state-of-the-art procedure for the routine culture of M. tuberculosis in both developed and developing countries. Useful specimens include sputum, induced sputum and stools collected in quaternary ammonium preservative-containing sterile cans. The usefulness of other non-invasive specimens remains to be evaluated. Specimens can be collected in a diagnosis kit also containing sampling materials, instructions, laboratory requests and informed consent. Automated direct LED fluorescence microscopy after auramine staining precedes inoculation of an egg-lecithin-containing culture solid medium under microaerophilic atmosphere, inverted microscope reading or scanning video-imaging detection of colonies and colonies identification by recent molecular methods. This procedure should result in a diagnosis of pulmonary tuberculosis as fast as 5 days. It may be implemented in both developed and developing countries with automated steps replaceable by manual steps depending on local resources.

  20. Rapid Hip Osteoarthritis Development in a Patient with Anterior Acetabular Cyst with Sagittal Alignment Change

    Directory of Open Access Journals (Sweden)

    Yasuhiro Homma


    Full Text Available Rapidly destructive coxarthrosis (RDC is rare and develops unusual clinical course. Recent studies suggest multiple possible mechanisms of the development of RDC. However the exact mechanism of RDC is still not clear. The difficulty of the study on RDC is attributed to its rareness and the fact that the data before the onset of RDC is normally unavailable. In this report, we presented the patient having the radiographic data before the onset who had rapid osteoarthritis (OA development after contralateral THA, which meets the current criteria of RDC. We thought that the increased posterior tilt of the pelvis after THA reinforced the stress concentration at pre-existed anterior acetabular cyst, thereby the destruction of the cyst was occurred. As a result the rapid OA was developed. We think that there is the case of rapid osteoarthritis developing due to alternating load concentration by posterior pelvic tilt on preexisting anterior acetabular cyst such as our patient among the cases diagnosed as RDC without any identifiable etiology. The recognition of sagittal alignment changes and anterior acetabular cyst may play important role in prediction and prevention of the rapid hip osteoarthritis development similar to RDC.

  2. Rapid identification information and its influence on the perceived clues at a crime scene: An experimental study. (United States)

    de Gruijter, Madeleine; Nee, Claire; de Poot, Christianne J


    Crime scenes can always be explained in multiple ways. Traces alone do not provide enough information to infer a whole series of events that has taken place; they only provide clues for these inferences. CSIs need additional information to be able to interpret observed traces. In the near future, a new source of information that could help to interpret a crime scene and testing hypotheses will become available with the advent of rapid identification techniques. A previous study with CSIs demonstrated that this information had an influence on the interpretation of the crime scene, yet it is still unknown what exact information was used for this interpretation and for the construction of their scenario. The present study builds on this study and gains more insight into (1) the exact investigative and forensic information that was used by CSIs to construct their scenario, (2) the inferences drawn from this information, and (3) the kind of evidence that was selected at the crime scene to (dis)prove this scenario. We asked 48 CSIs to investigate a potential murder crime scene on the computer and explicate what information they used to construct a scenario and to select traces for analysis. The results show that the introduction of rapid ID information at the start of an investigation contributes to the recognition of different clues at the crime scene, but also to different interpretations of identical information, depending on the kind of information available and the scenario one has in mind. Furthermore, not all relevant traces were recognized, showing that important information can be missed during the investigation. In this study, accurate crime scenarios where mainly build with forensic information, but we should be aware of the fact that crime scenes are always contaminated with unrelated traces and thus be cautious of the power of rapid ID at the crime scene.

  3. Development of a PSA information management system

    Energy Technology Data Exchange (ETDEWEB)

    Ho, Seok; Dong Kyu, Kim; Sun Koo, Kang [Korea Power Engineering Company, Inc (Korea, Republic of)


    In general, Probabilistic Safety Agreement (PSA) is a very complicated work that uses and generates a lot of resources such as reports, procedures, drawings, assumptions, calculation sheets, PSA model, and so on. In many PSAs, however, the data, materials and knowledge considered and generated during performing PSA are scattered in many documents so that overall structure of PSA and information relationship between documents and models cannot easily be understood. To organize and manage all documents related to PSA, to capture knowledge of analysts, and finally to improve the quality of PSA, a PSA information management system (PIMS) was developed. The PIMS can manage all the documents of a PSA in a database and connect the causal relation between one information to another in the scattered documents via link. The PIMS can manage all the assumptions and technical basis used in PSA, and it can keep the record of the design changes the revision of PSA model. It can also control the review results of PSA models. The link of the PIMS can explicitly describe and reveal the expertise of the PSA analysts, and it enables the users to capture the knowledge and to understand the structure and contents of a PSA with ease. We are planning to apply the PIMS to the PSA of Shin Kori Units 1 and 2 as feasibility study and then to all the PSAs of the nuclear power plants in Korea. The PIMS is expected to contribute to enhancing the quality and confidence of PSA and reducing the efforts and costs of maintenance and update of PSA. (authors)

  4. Redesigning Health Information Systems in Developing Countries

    DEFF Research Database (Denmark)

    Mengiste, Shegaw Anagaw; Kimaro, Honest; Aanestad, Margunn


    Despite widespread aims to strengthen the Health Information System (HIS) as a tool for decentralised health care, there is a strong tendency in most developing countries that the HIS continues to reflect the central level's needs and requirements. The traditional design approach with little...... or no end user involvement results in a centralised HIS with an extensive, somewhat inappropriate, but also inflexible set of standards. Consequently, the HIS is not very useful for the wished-for decentralisation of health services, and there is an urgent need to redesign the existing HIS in order to make...... it locally relevant and appropriately decentralised. Based on a comparative case analysis of the HIS in Tanzania and Ethiopia, we offer practical recommendations on the way to achieve this redesign. A central design goal should be to achieve a balance between centralised control and local autonomy. Some...

    information technology systems. The current DoDI 5000.02 leaves IT project and program managers wondering how the current process applies to them, as the guidance is fairly rigid and does not allow for the flexibility required to appropriately manage IT programs. Until very recently, in comparison to the development of a traditional weapons system, IT programs seemed to have been viewed as a utility or service instead of a critical component to national security. Perhaps that is because data passing through cables cannot be observed with the naked senses and therefore an

  11. Rapid RNA-ligand interaction analysis through high-information content conformational and stability landscapes

    Energy Technology Data Exchange (ETDEWEB)

    Baird, Nathan J. [National Inst. of Health (NIH), Bethesda, MD (United States); Inglese, James [National Inst. of Health (NIH), Bethesda, MD (United States); Ferré-D’Amaré, Adrian R. [National Inst. of Health (NIH), Bethesda, MD (United States)


    The structure and biological properties of RNAs are a function of changing cellular conditions, but comprehensive, simultaneous investigation of the effect of multiple interacting environmental variables is not easily achieved. We have developed an efficient, high-throughput method to characterize RNA structure and thermodynamic stability as a function of multiplexed solution conditions using Förster resonance energy transfer (FRET). In a single FRET experiment using conventional quantitative PCR instrumentation, 19,400 conditions of MgCl2, ligand and temperature are analysed to generate detailed empirical conformational and stability landscapes of the cyclic diguanylate (c-di-GMP) riboswitch. This method allows rapid comparison of RNA structure modulation by cognate and non-cognate ligands. Landscape analysis reveals that kanamycin B stabilizes a non-native, idiosyncratic conformation of the riboswitch that inhibits c-di-GMP binding. Our research demonstrates that allosteric control of folding, rather than direct competition with cognate effectors, is a viable approach for pharmacologically targeting riboswitches and other structured RNA molecules.

  12. A rapid evidence-based service by librarians provided information to answer primary care clinical questions. (United States)

    McGowan, Jessie; Hogg, William; Rader, Tamara; Salzwedel, Doug; Worster, Danielle; Cogo, Elise; Rowan, Margo


    A librarian consultation service was offered to 88 primary care clinicians during office hours. This included a streamlined evidence-based process to answer questions in fewer than 20 min. This included a contact centre accessed through a Web-based platform and using hand-held devices and computers with Web access. Librarians were given technical training in evidence-based medicine, including how to summarise evidence. To describe the process and lessons learned from developing and operating a rapid response librarian consultation service for primary care clinicians. Evaluation included librarian interviews and a clinician exit satisfaction survey. Clinicians were positive about its impact on their clinical practice and decision making. The project revealed some important 'lessons learned' in the clinical use of hand-held devices, knowledge translation and training for clinicians and librarians. The Just-in-Time Librarian Consultation Service showed that it was possible to provide evidence-based answers to clinical questions in 15 min or less. The project overcame a number of barriers using innovative solutions. There are many opportunities to build on this experience for future joint projects of librarians and healthcare providers.

    Full Text Available The purpose of this paper is to provide basic dimensions for rapid training development in e-learning courses in education and business. Principally, it starts with defining task analysis and how to select tasks for analysis and task analysis methods for instructional design. To do this, first, learning and instructional technologies as visions of the future were discussed. Second, the importance of task analysis methods in rapid e-learning was considered, with learning technologies as asynchronous and synchronous e-learning development. Finally, rapid instructional design concepts and e-learning design strategies were defined and clarified with examples, that is, all steps for effective task analysis and rapid training development techniques based on learning and instructional design approaches were discussed, such as m-learning and other delivery systems. As a result, the concept of task analysis, rapid e-learning development strategies and the essentials of online course design were discussed, alongside learner interface design features for learners and designers.

  17. Characterisation of microcontaminants in Darwin Harbour, a tropical estuary of northern Australia undergoing rapid development. (United States)

    French, Veronica A; King, Susan Codi; Kumar, Anu; Northcott, Grant; McGuinness, Keith; Parry, David


    The detection of microcontaminants in aquatic environments raises concerns about their potential to exert ecotoxicological effects and impact human health. In contrast to freshwater habitats, little information is available on environmental concentrations in urban estuarine and marine environments. This study investigated an extensive range of organic and inorganic microcontaminants in the Darwin Harbour catchment, a tropical estuary in northern Australia undergoing rapid urbanisation and industrial development. We sampled wastewater effluent and surface water from seven sites in Darwin Harbour for pharmaceuticals and personal care products, alkylphenols, hormones, pesticides, herbicides and metals. In vitro bioassays were used to estimate the (anti)estrogenic and (anti)androgenic activities of samples. Seventy-nine of 229 organic microcontaminants analysed were detected at concentrations ranging from 0.01 to 20 μg/L, with acesulfame, paracetamol, cholesterol, caffeine, DEET and iopromide detected at the highest concentrations in wastewater effluent (20 μg/L, 17 μg/L, 11 μg/L, 11 μg/L, 10 μg/L and 7.6 μg/L, respectively). Levels of estrogenic activity ranged from estradiol equivalency quotients (EEQs) of Darwin Harbour. The measured concentration range of DEET was higher than ranges reported in previous studies.

    Jay, Kenneth; Schraefel, Mc; Andersen, Christoffer H; Ebbesen, Frederik S; Christiansen, David H; Skotte, Jørgen; Zebis, Mette K; Andersen, Lars L


    To determine the effect of small daily amounts of progressive resistance training on rapid force development of painful neck/shoulder muscles. 198 generally healthy adults with frequent neck/shoulder muscle pain (mean: age 43.1 years, computer use 93% of work time, 88% women, duration of pain 186 day during the previous year) were randomly allocated to 2- or 12 min of daily progressive resistance training with elastic tubing or to a control group receiving weekly information on general health. A blinded assessor took measures at baseline and at 10-week follow-up; participants performed maximal voluntary contractions at a static 90-degree shoulder joint angle. Rapid force development was determined as the rate of torque development and maximal muscle strength was determined as the peak torque. Compared with the control group, rate of torque development increased 31.0 Nm s(-1) [95% confidence interval: (1.33-11.80)] in the 2-min group and 33.2 Nm s(-1) (1.66-12.33) in the 12-min group from baseline to 10-week follow-up, corresponding to an increase of 16.0% and 18.2% for the two groups, respectively. The increase was significantly different compared to controls (Pmuscle strength increased only ~5-6% [mean and 95% confidence interval for 2- and 12-min groups to control, respectively: 2.5 Nm (0.05-0.73) and 2.2 Nm (0.01-0.70)]. No significant differences between the 2- and 12-min groups were evident. A weak but significant relationship existed between changes in rapid force development and pain (r = 0.27, Pmuscle strength and pain. Small daily amounts of progressive resistance training in adults with frequent neck/shoulder pain increases rapid force development and, to a less extent, maximal force capacity. © 2013 The Authors Clinical Physiology and Functional Imaging © 2013 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

  1. Development of an OP9 derived cell line as a robust model to rapidly study adipocyte differentiation.

    Directory of Open Access Journals (Sweden)

    Jacqueline M Lane

    Full Text Available One hallmark of obesity is adipocyte hypertrophy and hyperplasia. To gain novel insights into adipose biology and therapeutics, there is a pressing need for a robust, rapid, and informative cell model of adipocyte differentiation for potential RNAi and drug screens. Current models are prohibitive for drug and RNAi screens due to a slow differentiation time course and resistance to transfection. We asked if we could create a rapid, robust model of adipogenesis to potentially enable rapid functional and obesity therapeutic screens. We generated the clonal population OP9-K, which differentiates rapidly and reproducibly, and displays classic adipocyte morphology: rounded cell shape, lipid accumulation, and coalescence of lipids into a large droplet. We further validate the OP9-K cells as an adipocyte model system by microarray analysis of the differentiating transcriptome. OP9-K differentiates via known adipogenic pathways, involving the transcriptional activation and repression of common adipose markers Plin1, Gata2, C/Ebpα and C/Ebpβ and biological pathways, such as lipid metabolism, PPARγ signaling, and osteogenesis. We implemented a method to quantify lipid accumulation using automated microscopy and tested the ability of our model to detect alterations in lipid accumulation by reducing levels of the known master adipogenic regulator Pparγ. We further utilized our model to query the effects of a novel obesity therapeutic target, the transcription factor SPI1. We determine that reduction in levels of Spi1 leads to an increase in lipid accumulation. We demonstrate rapid, robust differentiation and efficient transfectability of the OP9-K cell model of adipogenesis. Together with our microscopy based lipid accumulation assay, adipogenesis assays can be achieved in just four days' time. The results of this study can contribute to the development of rapid screens with the potential to deepen our understanding of adipose biology and efficiently

  12. Undergraduate medical education: tendencies and requirements in a rapidly developing Europe. (United States)

    Breipohl, W; Johansson, C; Hansis, M; Steiger, J; Naguro, T; Müller, K; Mestres, P


    This study pinpoints the necessity to constantly monitor local approaches in undergraduate medical education on an inter-European scale. Traditional undergraduate medical curricula need restructuring to account for the increasing amount of medical knowledge and rapid changes and developments in societies, nosology, therapy and IT. European undergraduate medical curricula should be harmonized not egalized, with a focus on inter-European sharing of resources, mobility, credit (allocation, accumulation and transfer), definition of European and trans-European mission statements, identification of quality metrics, advice on dealing with conflicting aims such as specialization and generalization, on communicating core knowledge instead of providing overabundance of information, and on introducing multifaceted teaching and learning methods, as well as providing strategies for life long learning. Sound medical education can no longer and nowhere be considered under the autonomous auspices of individual Medical Schools or national philosophies. It has to be perceived and structured as a competitive and flexible approach which promotes life long learning of teachers, students, physicians and other related staff with international awareness. It is stressed that student and staff mobility, as well as virtual mobility in the form of worldwide available teaching modules and expertise have to be incorporated into national medical curricula. This is to guarantee up-to-date education in support of patient demands, future professionality and competitiveness of students, physicians and Public Health System institutions. The formal approaches of traditional subject related curricula as well as problem based learning must be linked with quality approved state of the art ODL, evaluated international CME strategies and training in the utilization of IT in preparation of lifelong learning. Strategies for the use of IT need updating on a regular basis to diminish the gap between

  14. Development of Experimental Setup of Metal Rapid Prototyping Machine using Selective Laser Sintering Technique (United States)

    Patil, S. N.; Mulay, A. V.; Ahuja, B. B.


    Unlike in the traditional manufacturing processes, additive manufacturing as rapid prototyping, allows designers to produce parts that were previously considered too complex to make economically. The shift is taking place from plastic prototype to fully functional metallic parts by direct deposition of metallic powders as produced parts can be directly used for desired purpose. This work is directed towards the development of experimental setup of metal rapid prototyping machine using selective laser sintering and studies the various parameters, which plays important role in the metal rapid prototyping using SLS technique. The machine structure in mainly divided into three main categories namely, (1) Z-movement of bed and table, (2) X-Y movement arrangement for LASER movements and (3) feeder mechanism. Z-movement of bed is controlled by using lead screw, bevel gear pair and stepper motor, which will maintain the accuracy of layer thickness. X-Y movements are controlled using timing belt and stepper motors for precise movements of LASER source. Feeder mechanism is then developed to control uniformity of layer thickness metal powder. Simultaneously, the study is carried out for selection of material. Various types of metal powders can be used for metal RP as Single metal powder, mixture of two metals powder, and combination of metal and polymer powder. Conclusion leads to use of mixture of two metals powder to minimize the problems such as, balling effect and porosity. Developed System can be validated by conducting various experiments on manufactured part to check mechanical and metallurgical properties. After studying the results of these experiments, various process parameters as LASER properties (as power, speed etc.), and material properties (as grain size and structure etc.) will be optimized. This work is mainly focused on the design and development of cost effective experimental setup of metal rapid prototyping using SLS technique which will gives the feel of

  15. Geographic Information Systems and Web Page Development (United States)

    Reynolds, Justin


    The Facilities Engineering and Architectural Branch is responsible for the design and maintenance of buildings, laboratories, and civil structures. In order to improve efficiency and quality, the FEAB has dedicated itself to establishing a data infrastructure based on Geographic Information Systems, GIS. The value of GIS was explained in an article dating back to 1980 entitled "Need for a Multipurpose Cadastre" which stated, "There is a critical need for a better land-information system in the United States to improve land-conveyance procedures, furnish a basis for equitable taxation, and provide much-needed information for resource management and environmental planning." Scientists and engineers both point to GIS as the solution. What is GIS? According to most text books, Geographic Information Systems is a class of software that stores, manages, and analyzes mapable features on, above, or below the surface of the earth. GIS software is basically database management software to the management of spatial data and information. Simply put, Geographic Information Systems manage, analyze, chart, graph, and map spatial information. GIS can be broken down into two main categories, urban GIS and natural resource GIS. Further still, natural resource GIS can be broken down into six sub-categories, agriculture, forestry, wildlife, catchment management, archaeology, and geology/mining. Agriculture GIS has several applications, such as agricultural capability analysis, land conservation, market analysis, or whole farming planning. Forestry GIs can be used for timber assessment and management, harvest scheduling and planning, environmental impact assessment, and pest management. GIS when used in wildlife applications enables the user to assess and manage habitats, identify and track endangered and rare species, and monitor impact assessment.

  16. Development of a Mobile Application for Disaster Information and Response (United States)

    Stollberg, B.


    The Joint Research Centre (JRC) of the European Commission (EC) started exploring current technology and internet trends in order to answer the question if post-disaster situation awareness can be improved by community involvement. An exploratory research project revolves around the development of an iPhone App to provide users with real-time information about disasters and give them the possibility to send information in the form of a geo-located image and/or text back. Targeted users include professional emergency responders of the Global Disaster Alert and Coordination System (GDACS), as well as general users affected by disasters. GDACS provides global multi-hazard disaster monitoring and alerting for earthquakes, tsunamis, tropical cyclones, floods and volcanoes. It serves to consolidate and improve the dissemination of disaster-related information, in order to improve the coordination of international relief efforts. The goal of the exploratory research project is to extract and feedback useful information from reports shared by the community for improving situation awareness and providing ground truth for rapid satellite-based mapping. From a technological point of view, JRC is focusing on interoperability of field reporting software and is working with several organizations to develop standards and reference implementations of an interoperable mobile information platform. The iPhone App developed by JRC provides on one hand information about GDACS alerts and on the other hand the possibility for the users to send reports about a selected disaster back to JRC. iPhones are equipped with a camera and (apart from the very first model) a GPS receiver. This offers the possibility to transmit pictures and also the location for every sent report. A test has shown that the accuracy of the location can be expected to be in the range of 50 meters (iPhone 3GS) and respectively 5 meters (iPhone 4). For this reason pictures sent by the new iPhone generation can be very

  17. Using Simulation to Develop Care Models for Rapid Response and Code Teams at a Satellite Facility. (United States)

    Rule, Amy R L; Snider, Julie; Marshall, Cheryl; Kramer, Kathleen; Geis, Gary L; Tegtmeyer, Ken; Gosdin, Craig H


    Our institution recently completed an expansion of an acute care inpatient unit within a satellite hospital that does not include an on-site ICU or PICU. Because of expected increases in volume and acuity, new care models for Rapid Response Teams (RRTs) and Code Blue Teams were necessary. Using simulation-based training, our objectives were to define the optimal roles and responsibilities for team members (including ICU physicians via telemedicine), refine the staffing of RRTs and code Teams, and identify latent safety threats (LSTs) before opening the expanded inpatient unit. The laboratory-based intervention consisted of 8 scenarios anticipated to occur at the new campus, with each simulation followed by an iterative debriefing process and a 30-minute safety talk delivered within 4-hour interprofessional sessions. In situ sessions were delivered after construction and before patients were admitted. A total of 175 clinicians completed a 4-hour course in 17 sessions. Over 60 clinicians participated during 2 in situ sessions before the opening of the unit. Eleven team-level knowledge deficits, 19 LSTs, and 25 system-level issues were identified, which directly informed changes and refinements in care models at the bedside and via telemedicine consultation. Simulation-based training can assist in developing staffing models, refining the RRT and code processes, and identify LSTs in a new pediatric acute care unit. This training model could be used as a template for other facilities looking to expand pediatric acute care at outlying smaller, more resource-limited facilities to evaluate new teams and environments before patient exposure.

  20. IL-6 trans-Signaling-Dependent Rapid Development of Cytotoxic CD8+ T Cell Function

    Directory of Open Access Journals (Sweden)

    Jan P. Böttcher


    Full Text Available Immune control of infections with viruses or intracellular bacteria relies on cytotoxic CD8+ T cells that use granzyme B (GzmB for elimination of infected cells. During inflammation, mature antigen-presenting dendritic cells instruct naive T cells within lymphoid organs to develop into effector T cells. Here, we report a mechanistically distinct and more rapid process of effector T cell development occurring within 18 hr. Such rapid acquisition of effector T cell function occurred through cross-presenting liver sinusoidal endothelial cells (LSECs in the absence of innate immune stimulation and known costimulatory signaling. Rather, interleukin-6 (IL-6 trans-signaling was required and sufficient for rapid induction of GzmB expression in CD8+ T cells. Such LSEC-stimulated GzmB-expressing CD8+ T cells further responded to inflammatory cytokines, eliciting increased and protracted effector functions. Our findings identify a role for IL-6 trans-signaling in rapid generation of effector function in CD8+ T cells that may be beneficial for vaccination strategies.

    Abay, Serebe; Addissie, Adamu; Davey, Gail; Farsides, Bobbie; Addissie, Thomas


    Informed consent is a key component of bio-medical research involving human participants. However, obtaining informed consent is challenging in low literacy and resource limited settings. Rapid Ethical Assessment (REA) can be used to contextualize and simplify consent information within a given study community. The current study aimed to explore the effects of social, cultural, and religious factors during informed consent process on a proposed HPV-serotype prevalence study. A qualitative community-based REA was conducted in Adigudom and Mynebri Kebeles, Northern Ethiopia, from July to August 2013. Data were collected by a multi-disciplinary team using open ended questions concerning informed consent components in relation to the parent study. The team conducted one-to-one In-Depth Interviews (IDI) and Focus Group Discussions (FGDs) with key informants and community members to collect data based on the themes of the study. Tape recorded data were transcribed in Tigrigna and then translated into English. Data were categorized and thematically analyzed using open coding and content analysis based on pre-defined themes. The REA study revealed a number of socio-cultural issues relevant to the proposed study. Low community awareness about health research, participant rights and cervical cancer were documented. Giving a vaginal sample for testing was considered to be highly embarrassing, whereas giving a blood sample made participants worry that they might be given a result without the possibility of treatment. Verbal consent was preferred to written consent for the proposed study. This rapid ethical assessment disclosed important socio-cultural issues which might act as barriers to informed decision making. The findings were important for contextual modification of the Information Sheet, and to guide the best consent process for the proposed study. Both are likely to have enabled participants to understand the informed consent better and consequently to comply with the

    Flávia Ferreira


    Full Text Available Introduction. We discuss the concept of core competencies applied to policies for teaching and training information professionals, particularly librarians. Method. Sixty graduates of the Institute were employed as information professionals. These sixty were asked to attribute degrees of importance to specific items associated with knowledge and skills that, within the scope of this research, were considered core competencies for meeting the demands of their jobs. Participants were also asked to cite knowledge they acquired in school and knowledge they use in exercising their profession, the skills that they consider necessary but that they did not gain in school, and the difficulties they encounter in exercising their profession and for which they were not sufficiently well prepared. Analysis. Both quantitative and qualitative data analyses were performed. The data were tabulated using Access and several reports and cross-tabulations were generated. Results. The results suggest a gulf between knowledge and skills acquired in library school and those that are required by the job market. In particular, participants lacked the skills they needed to work with information and communication technologies. Conclusion. The concept of core competencies is increasingly taken into account by the productive sector of the economy. The educational system ought to keep up with this change. The empirical research described shows that there is a need to establish advanced and modern policies for the education of librarians, participants in the market for information professionals.

    Quenchbody (Q-body) is a novel fluorescent biosensor based on the antigen-dependent removal of a quenching effect on a fluorophore attached to antibody domains. In order to develop a method using Q-body for the quantitative determination of deoxynivalenol (DON), a trichothecene mycotoxin produced by some Fusarium species, anti-DON Q-body was synthesized from the sequence information of a monoclonal antibody specific to DON. When the purified anti-DON Q-body was mixed with DON, a dose-dependent increase in the fluorescence intensity was observed and the detection range was between 0.0003 and 3 mg L{sup −1}. The coefficients of variation were 7.9% at 0.003 mg L{sup −1}, 5.0% at 0.03 mg L{sup −1} and 13.7% at 0.3 mg L{sup −1}, respectively. The limit of detection was 0.006 mg L{sup −1} for DON in wheat. The Q-body showed an antigen-dependent fluorescence enhancement even in the presence of wheat extracts. To validate the analytical method using Q-body, a spike-and-recovery experiment was performed using four spiked wheat samples. The recoveries were in the range of 94.9–100.2%. The concentrations of DON in twenty-one naturally contaminated wheat samples were quantitated by the Q-body method, LC-MS/MS and an immunochromatographic assay kit. The LC-MS/MS analysis showed that the levels of DON contamination in the samples were between 0.001 and 2.68 mg kg{sup −1}. The concentrations of DON quantitated by LC-MS/MS were more strongly correlated with those using the Q-body method (R{sup 2} = 0.9760) than the immunochromatographic assay kit (R{sup 2} = 0.8824). These data indicate that the Q-body system for the determination of DON in wheat samples was successfully developed and Q-body is expected to have a range of applications in the field of food safety. - Highlights: • A rapid method for quantitation of DON using Q-body has been developed. • A recovery test using the anti-DON Q-body was performed. • The concentrations of DON in wheat

  8. Rapid tolerance development to the NREM sleep promoting effect of alcohol. (United States)

    Sharma, Rishi; Sahota, Pradeep; Thakkar, Mahesh M


    Alcohol tolerance is a major contributor towards the development of alcohol dependence. Does alcohol intake result in rapid tolerance development to alcohol induced NREM sleep promotion? This has never been examined. Our objective was to examine whether two bouts of alcohol consumption on consecutive days results in rapid tolerance development to alcohol-induced NREM sleep promotion. N/A. N/A. C57BL/6J mice. Mice (N = 5) were implanted with sleep electrodes using standard surgical conditions. Following postoperative recovery and habituation, the experiment was begun. On baseline day, water bottle changes were performed at 10:00 (3 h after dark onset) and 14:00 to mimic conditions during alcohol consumption days. On next 2 days, (Days 1 and 2) mice were allowed to self-administer alcohol (20% v/v) for 4 h beginning at 10:00 and ending at 14:00. Sleep-wakefulness was continuously recorded from 10:00 to 18:00 (8 h; 4 h during alcohol + 4 h post-alcohol) on all 3 days. Although mice consumed comparable amounts of alcohol on Days 1 and 2, NREM sleep and wakefulness were significantly and differentially affected during 4 h post-alcohol period. A robust alcohol-induced NREM sleep promotion was observed on Day 1. However, no such sleep promotion was observed on Day 2, suggesting rapid tolerance development. Our study is the first to demonstrate that alcohol consumption for two consecutive days results in development of rapid tolerance to alcohol-induced sleep promotion.

  12. Invasive species information networks: Collaboration at multiple scales for prevention, early detection, and rapid response to invasive alien species (United States)

    Simpson, Annie; Jarnevich, Catherine S.; Madsen, John; Westbrooks, Randy G.; Fournier, Christine; Mehrhoff, Les; Browne, Michael; Graham, Jim; Sellers, Elizabeth A.


    Accurate analysis of present distributions and effective modeling of future distributions of invasive alien species (IAS) are both highly dependent on the availability and accessibility of occurrence data and natural history information about the species. Invasive alien species monitoring and detection networks (such as the Invasive Plant Atlas of New England and the Invasive Plant Atlas of the MidSouth) generate occurrence data at local and regional levels within the United States, which are shared through the US National Institute of Invasive Species Science. The Inter-American Biodiversity Information Network's Invasives Information Network (I3N), facilitates cooperation on sharing invasive species occurrence data throughout the Western Hemisphere. The I3N and other national and regional networks expose their data globally via the Global Invasive Species Information Network (GISIN). International and interdisciplinary cooperation on data sharing strengthens cooperation on strategies and responses to invasions. However, limitations to effective collaboration among invasive species networks leading to successful early detection and rapid response to invasive species include: lack of interoperability; data accessibility; funding; and technical expertise. This paper proposes various solutions to these obstacles at different geographic levels and briefly describes success stories from the invasive species information networks mentioned above. Using biological informatics to facilitate global information sharing is especially critical in invasive species science, as research has shown that one of the best indicators of the invasiveness of a species is whether it has been invasive elsewhere. Data must also be shared across disciplines because natural history information (e.g. diet, predators, habitat requirements, etc.) about a species in its native range is vital for effective prevention, detection, and rapid response to an invasion. Finally, it has been our

  13. Utility and Usability of the Rapid Assessment of Hospital Procurement Barriers in Donation (RAPiD) as a Tool for OPO Hospital Development Staff. (United States)

    Alolod, Gerard P; Traino, Heather M; Siminoff, Laura A


    Few systematic assessment tools are available to organ procurement organizations (OPOs) for evaluating donation climates of hospitals in their donation service areas (DSAs). The Rapid Assessment of hospital Procurement barriers in Donation (RAPiD) was developed for OPO hospital development staff to assess the organ donation climate of hospitals. To implement a national test of the RAPiD to examine its efficacy and usability by OPO hospital development staff. Two-arm randomized design, comparing implementation of RAPiD protocol between qualitatively trained researchers (n = 7) and OPO hospital development staff (n = 24); all evaluators received the same training assessments of high-yield hospitals. A total of 77 hospitals in DSAs of 8 OPOs. A total of 2552 health-care providers (HCPs) in high organ donor potential units. Twenty-four donation-related attitudes, knowledge, and behaviors. More HCPs interviewed in the autonomous condition were positive toward the concept of organ donation. However, HCPs in the assisted condition were more candid about and critical of the OPO. As for knowledge, fewer HCPs in the autonomous condition reported familiarity with the donation process, need for donors, and generally accepted timely referral criteria. With respect to behaviors, more respondents in the autonomous condition reported frequent or occasional contact with the OPO and routine or occasional referral criteria use. Due to issues of bias, inadequate research experience, conflicts of interest, and ongoing OPO hospital development initiatives, the RAPiD's usability by OPO-based hospital development staff is questionable and not recommended in its current form. A next generation of the RAPiD is described for future consideration. © 2016, NATCO.

    Tsai, Shinn Shyong; Chang, Yeng Ling; Huang, Yen Li; Liu, Hung Jen; Ke, Guan Ming; Chiou, Chwei Jang; Hsieh, Yao Ching; Chang, Tsung Chou; Cheng, Li Ting; Chuang, Kuo Pin


    There are no effective antiviral treatments for pigeon circovirus (PiCV); thus, rapid diagnosis is critical for effective control of the disease caused by this virus. The recent development of a novel LAMP technique that amplifies nucleic acids rapidly with high specificity and sensitivity under isothermal conditions has overcome some of the deficiencies of nucleic-acid-based diagnostic tests. We established a LAMP method for rapid detection of PiCV using two pairs of primers that were designed from PiCV and compared its sensitivity and specificity with that of PCR. Amplification by LAMP was optimal at 63 °C for 60 min. The detection limit was nearly 0.5 pg of PiCV DNA, making it ten times more sensitive than PCR. There was no cross-reaction with porcine circovirus type 2 (PCV2), pigeon Trichomonas gallinae, or pigeon herpesvirus (PHV) under the same conditions. The assay also successfully detected the pathogen DNA in the tissues of infected pigeons. This is the first report indicating that LAMP is a valuable, rapid method of detecting PiCV with high sensitivity and specificity.

  17. Development of a double-antibody sandwich ELISA for rapid detection of Bacillus Cereus in food (United States)

    Zhu, Longjiao; He, Jing; Cao, Xiaohan; Huang, Kunlun; Luo, Yunbo; Xu, Wentao


    Bacillus cereus is increasingly recognized as one of the major causes of food poisoning in the industrialized world. In this paper, we describe a sensitive double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) that was developed for rapid detection of B. cereus in food to minimize the risk of contamination. The polyclonal antibody (pAb) and monoclonal antibodies (mAbs) specific to B. cereus were generated from rabbit antiserum and mouse ascites, respectively, using the octanoic acid/saturated ammonium sulfate precipitation method and protein A-sepharose columns. IgG-isotype mAbs were specially developed to undergo a novel peripheral multiple sites immunization for rapid gain of hybridomas and a subtractive screen was used to eliminate cross reactivity with closely related species such as Bacillus thuringiensis, B. subtilis, B. licheniformis and B. perfringens. The linear detection range of the method was approximately 1 × 104–2.8 × 106 cells/mL with a detection limit (LOD) of 0.9 × 103 cells/mL. The assay was able to detect B. cereus when the samples were prepared in meat with various pathogens. The newly developed analytical method provides a rapid method to sensitively detect B. cereus in food specimens. PMID:26976753

In this article, we aimed to evaluate the effect of social information (positive, negative, or no information related to the character of the target on subjective (perceived and felt valence and arousal, physiological (facial mimicry as well as on neural (P100 and N170 responses to dynamic emotional facial expressions (EFE that varied from neutral to one of the six basic emotions. Across three studies, the results showed reduced ratings of valence and arousal of EFE associated with incongruent social information (Study 1, increased electromyographical responses (Study 2, and significant modulation of P100 and N170 components (Study 3 when EFE were associated with social (positive and negative information (vs. no information. These studies revealed that positive or negative social information reduces subjective responses to incongruent EFE and produces a similar neural and physiological boost of the early perceptual processing of EFE irrespective of their congruency. In conclusion, the article suggests that the presence of positive or negative social context modulates early physiological and neural activity preceding subsequent behavior.

  8. Can complexity science inform physician leadership development? (United States)

    Grady, Colleen Marie


    Purpose The purpose of this paper is to describe research that examined physician leadership development using complexity science principles. Design/methodology/approach Intensive interviewing of 21 participants and document review provided data regarding physician leadership development in health-care organizations using five principles of complexity science (connectivity, interdependence, feedback, exploration-of-the-space-of-possibilities and co-evolution), which were grouped in three areas of inquiry (relationships between agents, patterns of behaviour and enabling functions). Findings Physician leaders are viewed as critical in the transformation of healthcare and in improving patient outcomes, and yet significant challenges exist that limit their development. Leadership in health care continues to be associated with traditional, linear models, which are incongruent with the behaviour of a complex system, such as health care. Physician leadership development remains a low priority for most health-care organizations, although physicians admit to being limited in their capacity to lead. This research was based on five principles of complexity science and used grounded theory methodology to understand how the behaviours of a complex system can provide data regarding leadership development for physicians. The study demonstrated that there is a strong association between physician leadership and patient outcomes and that organizations play a primary role in supporting the development of physician leaders. Findings indicate that a physician's relationship with their patient and their capacity for innovation can be extended as catalytic behaviours in a complex system. The findings also identified limiting factors that impact physicians who choose to lead, such as reimbursement models that do not place value on leadership and medical education that provides minimal opportunity for leadership skill development. Practical Implications This research provides practical

  9. Assessing health systems for type 1 diabetes in sub-Saharan Africa: developing a 'Rapid Assessment Protocol for Insulin Access'

    Directory of Open Access Journals (Sweden)

    de Courten Maximilian


    Full Text Available Abstract Background In order to improve the health of people with Type 1 diabetes in developing countries, a clear analysis of the constraints to insulin access and diabetes care is needed. We developed a Rapid Assessment Protocol for Insulin Access, comprising a series of questionnaires as well as a protocol for the gathering of other data through site visits, discussions, and document reviews. Methods The Rapid Assessment Protocol for Insulin Access draws on the principles of Rapid Assessment Protocols which have been developed and implemented in several different areas. This protocol was adapted through a thorough literature review on diabetes, chronic condition management and medicine supply in developing countries. A visit to three countries in sub-Saharan Africa and meetings with different experts in the field of diabetes helped refine the questionnaires. Following the development of the questionnaires these were tested with various people familiar with diabetes and/or healthcare in developing countries. The Protocol was piloted in Mozambique then refined and had two further iterations in Zambia and Mali. Translations of questionnaires were made into local languages when necessary, with back translation to ensure precision. Results In each country the protocol was implemented in 3 areas – the capital city, a large urban centre and a predominantly rural area and their respective surroundings. Interviews were carried out by local teams trained on how to use the tool. Data was then collected and entered into a database for analysis. Conclusion The Rapid Assessment Protocol for Insulin Access was developed to provide a situational analysis of Type 1 diabetes, in order to make recommendations to the national Ministries of Health and Diabetes Associations. It provided valuable information on patients' access to insulin, syringes, monitoring and care. It was thus able to sketch a picture of the health care system with regards to its ability to

  16. Development of a highly sensitive lateral immunochromatographic assay for rapid detection of Vibrio parahaemolyticus. (United States)

    Liu, Xinfeng; Guan, Yuyao; Cheng, Shiliang; Huang, Yidan; Yan, Qin; Zhang, Jun; Huang, Guanjun; Zheng, Jian; Liu, Tianqiang


    Vibrio parahaemolyticus is widely present in brackish water all over the world, causing infections in certain aquatic animals. It is also a foodborne pathogen that causes diarrhea in humans. The aim of this study is to develop an immunochromatographic lateral flow assay (LFA) for rapid detection of V. parahaemolyticus in both aquatic products and human feces of diarrheal patients. Two monoclonal antibody (MAb) pairs, GA1a-IC9 and IC9-KB4c, were developed and proven to be highly specific and sensitive to V. parahaemolyticus. Based on the two MAb pairs, two types of LFA strips were prepared. Their testing limits for V. parahaemolyticus culture were both 1.2×103CFU/ml. The diagnostic sensitivities and specificities were both 100% for the 32 tested microbial species, including 6 Vibrio species. Subsequently, the LFA strips were used to test Whiteleg shrimps and human feces. The type II strip showed a higher diagnostic sensitivity. Its sensitivity and specificity for hepatopancreas and fecal samples from 13 Whiteleg shrimps and fecal samples from 146 human diarrheal patients were all 100%. In conclusion, our homemade type II LFA is a very promising testing device for rapid and convenient detection of V. parahaemolyticus infection not only in aquatic animals, but also in human diarrheal patients. This sensitive immunochromtographic LFA allows rapid detection of V. parahaemolyticus without requirement of culture enrichment. Copyright © 2016. Published by Elsevier B.V.

  20. Rapidly developing multimorbidity and disability in older adults: does social background matter? (United States)

    Calderón-Larrañaga, Amaia; Santoni, Giola; Wang, Hui Xin; Welmer, Anna-Karin; Rizzuto, Debora; Vetrano, Davide L; Marengoni, Alessandra; Fratiglioni, Laura


    Multimorbidity is among the most disabling geriatric conditions. In this study we explored whether a rapid development of multimorbidity potentiates its impact on the functional independence of older adults, and whether different sociodemographic factors play a role beyond the rate of chronic disease accumulation. A random sample of persons aged ≥60 years (n = 2387) from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K) was followed over 6 years. The speed of multimorbidity development was estimated as the rate of chronic disease accumulation (linear mixed models) and further dichotomized into the upper versus the three lower rate quartiles. Binomial negative mixed models were used to analyse the association between speed of multimorbidity development and disability (impaired basic and instrumental activities of daily living), expressed as the incidence rate ratio (IRR). The effect of sociodemographic factors, including sex, education, occupation and social network, was investigated. The risk of new activity impairment was higher among participants who developed multimorbidity faster (IRR 2.4, 95% CI 1.9-3.1) compared with those who accumulated diseases more slowly over time, even after considering the baseline number of chronic conditions. Only female sex (IRR for women vs. men 1.6, 95% CI 1.2-2.0) and social network (IRR for poor vs. rich social network 1.7, 95% CI 1.3-2.2) showed an effect on disability beyond the rate of chronic disease accumulation. Rapidly developing multimorbidity is a negative prognostic factor for disability. However, sociodemographic factors such as sex and social network may determine older adults' reserves of functional ability, helping them to live independently despite rapid accumulation of chronic conditions.

  2. Black Carbon and Kerosene Lighting: An Opportunity for Rapid Action on Climate Change and Clean Energy for Development

    Energy Technology Data Exchange (ETDEWEB)

    Jacobson, Arne [Humboldt State Univ., MN (United States). Schatz Energy Research Center; Bond, Tami C. [Univ. of Illinois at Urbana-Champaign, IL (United States). Dept. of Civil and Environmental Engineering; Lam, Nicholoas L. [Univ. of California, Berkeley, CA (United States). Dept. of Environmental Health Sciences; Hultman, Nathan [The Brookings Institution, Washington, DC (United States)


    Replacing inefficient kerosene lighting with electric lighting or other clean alternatives can rapidly achieve development and energy access goals, save money and reduce climate warming. Many of the 250 million households that lack reliable access to electricity rely on inefficient and dangerous simple wick lamps and other kerosene-fueled light sources, using 4 to 25 billion liters of kerosene annually to meet basic lighting needs. Kerosene costs can be a significant household expense and subsidies are expensive. New information on kerosene lamp emissions reveals that their climate impacts are substantial. Eliminating current annual black carbon emissions would provide a climate benefit equivalent to 5 gigatons of carbon dioxide reductions over the next 20 years. Robust and low-cost technologies for supplanting simple wick and other kerosene-fueled lamps exist and are easily distributed and scalable. Improving household lighting offers a low-cost opportunity to improve development, cool the climate and reduce costs.

  4. Impaired encoding of rapid pitch information underlies perception and memory deficits in congenital amusia. (United States)

    Albouy, Philippe; Cousineau, Marion; Caclin, Anne; Tillmann, Barbara; Peretz, Isabelle


    Recent theories suggest that the basis of neurodevelopmental auditory disorders such as dyslexia or specific language impairment might be a low-level sensory dysfunction. In the present study we test this hypothesis in congenital amusia, a neurodevelopmental disorder characterized by severe deficits in the processing of pitch-based material. We manipulated the temporal characteristics of auditory stimuli and investigated the influence of the time given to encode pitch information on participants' performance in discrimination and short-term memory. Our results show that amusics' performance in such tasks scales with the duration available to encode acoustic information. This suggests that in auditory neuro-developmental disorders, abnormalities in early steps of the auditory processing can underlie the high-level deficits (here musical disabilities). Observing that the slowing down of temporal dynamics improves amusics' pitch abilities allows considering this approach as a potential tool for remediation in developmental auditory disorders.

  7. Interagency partnering for weed prevention--progress on development of a National Early Detection and Rapid Response System for Invasive Plants in the United States (United States)

    Westbrooks, R.; Westbrooks, R.


    Over the past 50 years, experience has shown that interagency groups provide an effective forum for addressing various invasive species issues and challenges on multiple land units. However, more importantly, they can also provide a coordinated framework for early detection, reporting, identification and vouchering, rapid assessment, and rapid response to new and emerging invasive plants in the United States. Interagency collaboration maximizes the use of available expertise, resources, and authority for promoting early detection and rapid response (EDRR) as the preferred management option for addressing new and emerging invasive plants. Currently, an interagency effort is underway to develop a National EDRR System for Invasive Plants in the United States. The proposed system will include structural and informational elements. Structural elements of the system include a network of interagency partner groups to facilitate early detection and rapid response to new invasive plants, including the Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW), State Invasive Species Councils, State Early Detection and Rapid Response Coordinating Committees, State Volunteer Detection and Reporting Networks, Invasive Plant Task Forces, and Cooperative Weed Management Areas. Informational elements and products being developed include Regional Invasive Plant Atlases, and EDRR Guidelines for EDRR Volunteer Network Training, Rapid Assessment and Rapid Response, and Criteria for Selection of EDRR Species. System science and technical support elements which are provided by cooperating state and federal scientists, include EDRR guidelines, training curriculum for EDRR volunteers and agency field personnel, plant identification and vouchering, rapid assessments, as well as predictive modeling and ecological range studies for invasive plant species.

  8. Genetic, epigenetic and exogenetic information in development and evolution. (United States)

    Griffiths, Paul E


    The idea that development is the expression of information accumulated during evolution and that heredity is the transmission of this information is surprisingly hard to cash out in strict, scientific terms. This paper seeks to do so using the sense of information introduced by Francis Crick in his sequence hypothesis and central dogma of molecular biology. It focuses on Crick's idea of precise determination. This is analysed using an information-theoretic measure of causal specificity. This allows us to reconstruct some of Crick's claims about information in transcription and translation. Crick's approach to information has natural extensions to non-coding regions of DNA, to epigenetic marks, and to the genetic or environmental upstream causes of those epigenetic marks. Epigenetic information cannot be reduced to genetic information. The existence of biological information in epigenetic and exogenetic factors is relevant to evolution as well as to development.

  9. How citizen seismology is transforming rapid public earthquake information: the example of LastQuake smartphone application and Twitter QuakeBot (United States)

    Bossu, R.; Etivant, C.; Roussel, F.; Mazet-Roux, G.; Steed, R.


    Smartphone applications have swiftly become one of the most popular tools for rapid reception of earthquake information for the public. Wherever someone's own location is, they can be automatically informed when an earthquake has struck just by setting a magnitude threshold and an area of interest. No need to browse the internet: the information reaches you automatically and instantaneously! One question remains: are the provided earthquake notifications always relevant for the public? A while after damaging earthquakes many eyewitnesses scrap the application they installed just after the mainshock. Why? Because either the magnitude threshold is set too high and many felt earthquakes are missed, or it is set too low and the majority of the notifications are related to unfelt earthquakes thereby only increasing anxiety among the population at each new update. Felt and damaging earthquakes are the ones of societal importance even when of small magnitude. LastQuake app and Twitter feed (QuakeBot) focuses on these earthquakes that matter for the public by collating different information threads covering tsunamigenic, damaging and felt earthquakes. Non-seismic detections and macroseismic questionnaires collected online are combined to identify felt earthquakes regardless their magnitude. Non seismic detections include Twitter earthquake detections, developed by the USGS, where the number of tweets containing the keyword "earthquake" is monitored in real time and flashsourcing, developed by the EMSC, which detect traffic surges on its rapid earthquake information website caused by the natural convergence of eyewitnesses who rush to the Internet to investigate the cause of the shaking that they have just felt. We will present the identification process of the felt earthquakes, the smartphone application and the 27 automatically generated tweets and how, by providing better public services, we collect more data from citizens.

  10. Development of Rapid Isothermal Amplification Assays for Detection of Phytophthora spp. in Plant Tissue. (United States)

    Miles, Timothy D; Martin, Frank N; Coffey, Michael D


    Several isothermal amplification techniques recently have been developed that are tolerant of inhibitors present in many plant extracts, which can reduce the need for obtaining purified DNA for running diagnostic assays. One such commercially available technique that has similarities with real-time polymerase chain reaction (PCR) for designing primers and a labeled probe is recombinase polymerase amplification (RPA). This technology was used to develop two simple and rapid approaches for detection of Phytophthora spp.: one genus-specific assay multiplexed with a plant internal control and the other species-specific assays for Phytophthora ramorum and P. kernoviae. All assays were tested for sensitivity (ranging from 3 ng to 1 fg of DNA) and specificity using DNA extracted from more than 136 Phytophthora taxa, 21 Pythium spp., 1 Phytopythium sp., and a wide range of plant species. The lower limit of linear detection using purified DNA was 200 to 300 fg of DNA in all pathogen RPA assays. Six different extraction buffers were tested for use during plant tissue maceration and the assays were validated in the field by collecting 222 symptomatic plant samples from over 50 different hosts. Only 56 samples were culture positive for Phytophthora spp. whereas 91 were positive using the Phytophthora genus-specific RPA test and a TaqMan real-time PCR assay. A technique for the generation of sequencing templates from positive RPA amplifications to confirm species identification was also developed. These RPA assays have added benefits over traditional technologies because they are rapid (results can be obtained in as little as 15 min), do not require DNA extraction or extensive training to complete, use less expensive portable equipment than PCR-based assays, and are significantly more specific than current immunologically based methods. This should provide a rapid, field-deployable capability for pathogen detection that will facilitate point-of-sample collection processing

  11. Identification of pollutant sources in a rapidly developing urban river catchment in China (United States)

    Huang, Jingshui; Yin, Hailong; Jomma, Seifeddine; Rode, Michael; Zhou, Qi


    Rapid economic development and urbanization worldwide cause serious ecological and environmental problems. A typical region that is in transition and requires systemic research for effective intervention is the rapidly developing city of Hefei in central P. R. China. In order to investigate the sources of pollutants over a one-year period in Nanfei River catchment that drains the city of Hefei, discharges were measured and water samples were taken and measured along the 14km river section at 10 sites for 4 times from 2013 to 2014. Overflow concentrations of combined sewer and separate storm drains were also measured by selecting 15 rain events in 4 typical drainage systems. Loads and budgets of water and different pollutant sources i.e., wastewater treatment plant (WWTP) effluent, urban drainage overflow, unknown wastewater were calculated. The water balance demonstrated that >70% of the discharge originated from WWTP effluent. Lack of clean upstream inflow thereby is threatening ecological safety and water quality. Furthermore, mass fluxes calculations revealed that >40% of the COD (Chemical Oxygen Demand) loads were from urban drainage overflow because of a large amount of discharge of untreated wastewater in pumping stations during rain events. WWTP effluent was the predominant source of the total nitrogen loads (>60%) and ammonia loads (>45%). However, the total phosphorous loads from three different sources are similar (˜1/3). Thus, our research provided a basis for appropriate and prior mitigation strategies (state-of-art of WWTP upgrade, sewer systems modification, storm water regulation and storage capacity improvement, etc.) for different precedence-controlled pollutants with the limited infrastructure investments in these rapidly developing urban regions.

  12. Bordetella trematum sepsis with shock in a diabetic patient with rapidly developing soft tissue infection. (United States)

    Majewski, Lorrance L; Nogi, Masayuki; Bankowski, Matthew J; Chung, Heath H


    Bordetella is a gram-negative, glucose non-fermenting bacillus, consisting of many host-associated species. B. trematum has previously been identified in wound infections, but rarely known to be a source of bacteremia. Currently, 16S rRNA sequencing represents the reference standard method by which identification is made. Herein, we present a case of fatal B. trematum bacteremia with septic shock. The presumed primary site of the infection was a rapidly developing left leg deep soft tissue infection without necrotizing fasciitis. B. trematum should now be considered as a significant pathogen in sepsis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Aimed at the detailed insight into the phonological ability of Serbian-speaking children of preschool age, with and without language impairment, the ability of rapid naming was examined. Method: Operationalization of the set goal was carried out by using the Test for evaluating reading and writing pre-skills. In describing and analyzing the obtained data, methods of descriptive and inferential statistics were used. The sample included 120 subjects of both gender, 40 children diagnosed with specific language impairment (SLI, age from 5,11 to 7 years, and 80 children with typical language development (TLD, age between 5,11 and 7 years, with no statistically significant differences in relation to age and gender of the participants. Results: Summing up the overall results and achievements of children with SLI and children with TLD, we concluded that there are statistically significant differences in the rapid naming between children with specific language impairment and children with typical language development. Conclusions: As it is a global trend to work on preventing disorders and obstructions, and phonological skills in this age are a timely indicator of the development of reading and writing skills, the examined children with SLI are at risk for the occurrence of obstructions and disorders in the area of reading and writing abilities.

    Full Text Available Abstract Background While integrated primary healthcare for the management of depression has been well researched, appropriate models of primary care for people with severe and persistent psychotic disorders are poorly understood. In 2010 the NSW (Australia Health Department commissioned a review of the evidence on "shared care" models of ambulatory mental health services. This focussed on critical factors in the implementation of these models in clinical practice, with a view to providing policy direction. The review excluded evidence about dementia, substance use and personality disorders. Methods A rapid review involving a search for systematic reviews on The Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects (DARE. This was followed by a search for papers published since these systematic reviews on Medline and supplemented by limited iterative searching from reference lists. Results Shared care trials report improved mental and physical health outcomes in some clinical settings with improved social function, self management skills, service acceptability and reduced hospitalisation. Other benefits include improved access to specialist care, better engagement with and acceptability of mental health services. Limited economic evaluation shows significant set up costs, reduced patient costs and service savings often realised by other providers. Nevertheless these findings are not evident across all clinical groups. Gains require substantial cross-organisational commitment, carefully designed and consistently delivered interventions, with attention to staff selection, training and supervision. Effective models incorporated linkages across various service levels, clinical monitoring within agreed treatment protocols, improved continuity and comprehensiveness of services. Conclusions "Shared Care" models of mental health service delivery require attention to multiple levels (from organisational to individual

  15. Tracking Change in rapid and eXtreme Development: A Challenge to SCM-tools?

    DEFF Research Database (Denmark)

    Christensen, Henrik Bærbak


    Software configuration management (SCM) has proved to be an invaluable part of developing and maintaining high quality software. The benefits are not for free however: SCM tool operations often divert your attention from your development task, sometimes you have to endure a long waiting time while...... the tool does its job, change descriptions must be memorised until your next check-in, etc. This kind of overhead and disruption does not fit well with fast-paced development processes like rapid prototyping, explorative programming, and eXtreme Programming that favour creativity, speed, and communication...... more that managerial rigour. In the cost/benefit equation the balance may tip in favour of not using any SCM tool or only using a fraction of its potential. We think SCM has something to offer such projects, and present some proposals that may allow SCM tools to better suit the characteristics of fast...

  20. Developing a clinical information system: the role of the chief information officer. (United States)

    Glaser, J


    Chief information officers (CIOs) must play a pivotal role in the formation and implementation of a clinical information system, the subset of an organizational information system that deals specifically with support of clinical care activities. Major elements include the applications software, technology and data architecture, databases, and analysis. The organizational structures and processes that manage the development of improvement activities, including the clinical information system itself, are just as vital to the design of an information system as the hardware and software. To develop, sustain, and advance an information infrastructure, the CIO must help establish certain organizational precursors, such as medical staff involvement, experience with quality improvement, and ability to meet data needs. The CIO must then work with the senior administrative and medical leadership in developing a vision for the information system. The CIO must also create new roles and knowledge for information system and medical staff members. Interaction between information services and medical staff is vitally important to the success of a clinical information system. Organizational committees and structures that Brigham and Women's Hospital in Boston put in place to formalize the relationship between information systems and medical staff include the Clinical Initiative Development Program and the Center for Applied Medical Information Systems Research. Improving the clinical management of care and the efficacy of care processes involves complex changes in organizational culture and processes, medical practice and information system applications, technologies, staff, and data.

  5. The Water-Energy-Food Nexus in a Rapidly Developing Resource Sector (United States)

    Allen, D. M.; Kirste, D. M.


    Technological advances and access to global markets have changed the rate at which resource exploitation takes place. The environmental impact of the rapid development and distribution of resources such as minerals and hydrocarbons has led to a greater potential for significant stress on water resources both in terms of quality and quantity. How and where those impacts manifest is crucial to determining appropriate risk management strategies. North East British Columbia has an abundance of shale gas reserves that are anticipated to be exploited at a large scale in coming years, primarily for export as liquefied natural gas (LNG). However, there is growing concern that fracking and other activities related to shale gas development pose risks to water quality and quantity in the region. Water lies at the center of the water-energy-food nexus, with an accelerating water demand for fracking and industrial operations as well as for domestic, environmental and agricultural uses. Climate change is also anticipated to alter the hydrologic regime, posing added stress to the water resource. This case study examines the water-energy-food nexus in the context of a region that is impacted by a rapidly developing resource sector, encompassing water demand/supply, climate change, interaction between deep aquifers and shallow aquifers/surface waters, water quality concerns related to fracking, land use disturbance, and community impacts. Due to the rapid rate of development, there are significant knowledge gaps in our understanding of the water resource. Currently agencies are undertaking water resource assessments and establishing monitoring sites. This research aims to assess water security in North East British Columbia in a coordinated fashion through various partnerships. In addition to collecting baseline knowledge and data, the study will evaluate risk and resilience indicators in relation to water security.

  11. Non-Obese Diabetic Mice Rapidly Develop Dramatic Sympathetic Neuritic Dystrophy (United States)

    Schmidt, Robert E.; Dorsey, Denise A.; Beaudet, Lucie N.; Frederick, Kathy E.; Parvin, Curtis A.; Plurad, Santiago B.; Levisetti, Matteo G.


    To address the pathogenesis of diabetic autonomic neuropathy, we have examined the sympathetic nervous system in non-obese diabetic (NOD) and streptozotocin (STZ)-induced diabetic mice, two models of type 1 diabetes, and the db/db mouse, a model of type 2 diabetes. After only 3 to 5 weeks of diabetes, NOD mice developed markedly swollen axons and dendrites (“neuritic dystrophy”) in the prevertebral superior mesenteric and celiac ganglia (SMG-CG), similar to the pathology described in diabetic STZ- and BBW-rat and man. Comparable changes failed to develop in the superior cervical ganglia of the NOD mouse or in the SMG-CG of non-diabetic NOD siblings. STZ-induced diabetic mice develop identical changes, although at a much slower pace and to a lesser degree than NOD mice. NOD-SCID mice, which are genetically identical to NOD mice except for the absence of T and B cells, do not develop diabetes or neuropathology comparable to diabetic NOD mice. However, STZ-treated NOD-SCID mice develop severe neuritic dystrophy, evidence against an exclusively autoimmune pathogenesis for autonomic neuropathy in this model. Chronically diabetic type 2 db/db mice fail to develop neuritic dystrophy, suggesting that hyperglycemia alone may not be the critical and sufficient element. The NOD mouse appears to be a valuable model of diabetic sympathetic autonomic neuropathy with unambiguous, rapidly developing neuropathology which corresponds closely to the characteristic pathology of other rodent models and man.

  12. Old knowledge and new technologies allow rapid development of model organisms. (United States)

    Cook, Charles E; Chenevert, Janet; Larsson, Tomas A; Arendt, Detlev; Houliston, Evelyn; Lénárt, Péter


    Until recently the set of "model" species used commonly for cell biology was limited to a small number of well-understood organisms, and developing a new model was prohibitively expensive or time-consuming. With the current rapid advances in technology, in particular low-cost high-throughput sequencing, it is now possible to develop molecular resources fairly rapidly. Wider sampling of biological diversity can only accelerate progress in addressing cellular mechanisms and shed light on how they are adapted to varied physiological contexts. Here we illustrate how historical knowledge and new technologies can reveal the potential of nonconventional organisms, and we suggest guidelines for selecting new experimental models. We also present examples of nonstandard marine metazoan model species that have made important contributions to our understanding of biological processes. © 2016 Cook et al.

    Sören Hansen

    Full Text Available The detection of Mycobacterium avium subsp. paratuberculosis (MAP infections in ruminants is crucial to control spread among animals and to humans. Cultivation of MAP is seen as the gold standard for detection, although it is very time consuming and labour intensive. In addition, several PCR assays have been developed to detect MAP in around 90 minutes, but these assays required highly sophisticated equipment as well as lengthy and complicated procedure.In this study, we have developed a rapid assay for the detection of MAP based on the recombinase polymerase amplification (RPA assay targeting a MAP specific region, the IS900 gene. The detection limit was 16 DNA molecules in 15 minutes as determined by the probit analysis on eight runs of the plasmid standard. Cross reactivity with other mycobacterial and environmentally associated bacterial strains was not observed. The clinical performance of the MAP RPA assay was tested using 48 MAP-positive and 20 MAP-negative blood, sperm, faecal and tissue samples. All results were compared with reads of a highly sensitive real-time PCR assay. The specificity of the MAP RPA assay was 100%, while the sensitivity was 89.5%.The RPA assay is quicker and much easier to handle than real-time PCR. All RPA reagents were cold-chain independent. Moreover, combining RPA assay with a simple extraction protocol will maximize its use at point of need for rapid detection of MAP.

  14. Development of a lateral flow immunochromatographic assay for the rapid diagnosis of Orf virus infections. (United States)

    A rapid and simple lateral-flow immunochromatographic assay (LFIA) was developed for the specific detection of Orf virus (ORFV) using two distinct monoclonal antibodies (MAbs: 5A5 and 6F2) against the ORFV ORF011 protein. The MAb 5A5 was conjugated with colloidal gold, and the MAb 6F2 and goat anti-mouse IgG were sprayed onto a nitrocellulose membrane in strips at positions designated test (T) and control (C), respectively. The results showed that samples of ORFV complexed with colloidal gold-conjugated MAb 5A5, were captured by MAb 6F2 at the T line resulting in the appearance of a purple band. When samples did not contain ORFV or when they contained a quantity of ORFV below the detection limit of the test, only the C line was visible. The analysis of sensitivity of the test demonstrated that the lowest detected quantity of ORFV was 2.03×10(3.0) TCID50/ml. Storage at room temperature for 6 months did not result in the loss of performance of the LFIA test. Using loop-mediated isothermal amplification (LAMP) as a reference test, the relative specificity and sensitivity of the LFIA test were determined to be 100% and 92.1%, respectively. Based on these results, the LFIA test developed may be a suitable tool for rapid on-site testing for ORFV infection. Copyright © 2016 Elsevier B.V. All rights reserved.

  15. Development of a Rapid Beam Emittance Measurement System using a Real-Time Beam Profile Monitor (United States)

    Kamakura, Keita; Hatanaka, Kichiji; Fukuda, Mitsuhiro; Yorita, Tetsuhiko; Ueda, Hiroshi; Saito, Takane; Morinobu, Shunpei; Nagayama, Keiichi; Tamura, Hitoshi; Yasuda, Yuusuke


    We have developed a rapid beam emittance measurement system for the injection beam of the K140 azimuthally varying field (AVF) cyclotron at Research Center for Nuclear Physics (RCNP). So far, a conventional emittance monitor has been used in a section of a medium energy beam transport (MEBT) system to evaluate the quality of the injected beam to the K400 ring cyclotron. Two kinds of emittance monitors were supplemented in the low energy beam line for evaluation of ion beams from ion sources. One of them is a conventional type consisting of two sets of position-variable slits and a three-wire profile monitor (TPM), similar to the one installed in the MEBT system of the AVF cyclotron. It takes about 30 min to get emittances in both the horizontal and vertical planes. For quick emittance measurements, we have developed a new system equipped with a set of fast moving slits with a fixed gap and a real-time beam profile monitor (BPM83) with a rotating helical wire. With this system the measurement time was considerably reduced to 70 s for both the horizontal and vertical emittances. Moreover the data analysis and graphical processing were completely automated. The overall measurement and analysis time was successfully minimized within 75 s. This rapid emittance measurement system has contributed to improve the beam quality by optimizing parameters of ion sources and the beam transport system.

  17. Complementary processing of haptic information by slowly and rapidly adapting neurons in the trigeminothalamic pathway. Electrophysiology, mathematical modeling and simulations of vibrissae-related neurons.

    Directory of Open Access Journals (Sweden)

    Abel eSanchez-Jimenez


    Full Text Available Tonic (slowly adapting and phasic (rapidly adapting primary afferents convey complementary aspects of haptic information to the central nervous system: object location and texture the former, shape the latter. Tonic and phasic neural responses are also recorded in all relay stations of the somatosensory pathway, yet it is unknown their role in both, information processing and information transmission to the cortex: we don’t know if tonic and phasic neurons process complementary aspects of haptic information and/or if these two types constitute two separate channels that convey complementary aspects of tactile information to the cortex. Here we propose to elucidate these two questions in the fast trigeminal pathway of the rat (PrV-VPM: principal trigeminal nucleus-ventroposteromedial thalamic nucleus. We analyze early and global behavior, latencies and stability of the responses of individual cells in PrV and medial lemniscus under 1-40 Hz stimulation of the whiskers in control and decorticated animals and we use stochastic spiking models and extensive simulations. Our results strongly suggest that in the first relay station of the somatosensory system (PrV: 1 tonic and phasic neurons process complementary aspects of whisker-related tactile information 2 tonic and phasic responses are not originated from two different types of neurons 3 the two responses are generated by the differential action of the somatosensory cortex on a unique type of PrV cell 4 tonic and phasic neurons do not belong to two different channels for the transmission of tactile information to the thalamus 5 trigeminothalamic transmission is exclusively performed by tonically firing neurons and 6 all aspects of haptic information are coded into low-pass, band-pass and high-pass filtering profiles of tonically firing neurons. Our results are important for both, basic research on neural circuits and information processing, and development of sensory neuroprostheses.

  18. Professional Development Needs of Novice Nursing Clinical Teachers: A Rapid Evidence Assessment. (United States)

    Jetha, Farah; Boschma, Geertje; Clauson, Marion


    The current nursing profession is challenged with a decreasing supply of competent clinical teachers due to several factors consequently impacting the quality of nursing education. To meet this demand, academic nursing programs are resorting to hiring expert nurses who may have little or no teaching experience. They need support during their transition from practice to teaching. Using the systematic approach of a Rapid Evidence Assessment (REA), scholarly literature was reviewed to identify existing professional development needs for novice clinical teachers as well as supportive strategies to aid the transition of experienced nurses into teaching practice. The REA included 29 relevant studies. Findings revealed three main professional development needs for novice clinical teachers and key supportive strategies. Based on these findings recommendations for best practices to support and prepare novice clinical teachers are presented.

  19. Rapid crown root development confers tolerance to zinc deficiency in rice

    Directory of Open Access Journals (Sweden)

    Amrit Kaur eNanda


    Full Text Available Zinc (Zn deficiency is one of the leading nutrient disorders in rice (Oryza sativa. Many studies have identified Zn efficient rice genotypes, but causal mechanisms for Zn deficiency tolerance remain poorly understood. Here we report a detailed study of the impact of Zn deficiency on crown root development of rice genotypes, differing in their tolerance to this stress. Zn deficiency delayed crown root development and plant biomass accumulation in both Zn efficient and inefficient genotypes, with the effects being much stronger in the latter. Zn efficient genotypes had developed new crown roots as early as three days after transplanting (DAT to a Zn deficient field and that was followed by a significant increase in total biomass by 7 DAT. Zn-inefficient genotypes developed few new crown roots and did not increase biomass during the first seven days following transplanting. This correlated with Zn efficient genotypes retranslocating a higher proportion of shoot Zn to their roots, compared to Zn inefficient genotypes. These latter genotypes were furthermore not efficient in utilizing the limited Zn for root development. Histological analyses indicated no anomalies in crown tissue of Zn-efficient or inefficient genotypes that would have suggested crown root emergence was impeded. We therefore conclude that the rate of crown root initiation was differentially affected by Zn deficiency between genotypes. Rapid crown root development, following transplanting, was identified as a main causative trait for tolerance to Zn deficiency and better Zn retranslocation from shoot to root was a key attribute of Zn-efficient genotypes.

  20. Development of a lateral flow immunoassay for rapid diagnosis of potato blackleg caused by Dickeya species. (United States)

    Safenkova, Irina V; Zaitsev, Ilya A; Varitsev, Yuri A; Byzova, Nadezhda A; Drenova, Natalia V; Zherdev, Anatoly V; Dzantiev, Boris B


    Early detection of potato infections is essential for effective disease management. The aim of this study was to develop a lateral flow immunoassay (LFIA) for rapid detection of a serious potato disease, potato blackleg, caused by Dickeya dianthicola and Dickeya solani. Polyclonal antibodies specific to different strains of Dickeya were obtained from rabbits after immunization with bacterial cells of D. dianthicola and D. solani. Enzyme-linked immunosorbent assay testing with use of a wide range of bacterial species showed that the polyclonal antibodies detect closely related strains of D. dianthicola and D. solani. Cross-reactivity with widespread pathogenic bacteria (nine species) and saprophytes of healthy potato plants was not detected. The LFIA based on the obtained antibodies and gold nanoparticles with average diameter of 20 nm was developed. Under optimized conditions, the LFIA method enabled the analysis of potato extracts within 10 min, with a visual limit of detection of 1 × 10 5  CFU/ml for leaves and 4 × 10 5  CFU/ml for tubers. The assay was tested on potato stem and tuber extracts, and the results of the LFIA were confirmed in 92.1% of samples using the real-time polymerase chain reaction. The findings confirmed that the developed LFIA could be used for monitoring blackleg infection without the need for special equipment or skills. Graphical Abstract The developed lateral flow immunoassay is an efficient tool for rapid detection of a serious potato disease, potato blackleg, caused by Dickeya dianthicola and Dickeya solani.

  3. Fat and Moisture Content in Chinese Fried Bread Sticks: Assessment and Rapid Near-Infrared Spectroscopic Method Development

    Directory of Open Access Journals (Sweden)

    Zhuqing Xiao


    Full Text Available Fried bread sticks (FBS are one of the most widely consumed deep fried food products in China. Understanding the fat and moisture content in FBS will help consumers make healthy food choices as well as assist food processors to provide FBS with desirable quality. Rapid Fourier transform near-infrared methods (FT-NIR were developed for determining fat and moisture content in FBS collected from 123 different vendors in Shanghai, China. FBS samples with minimum sample preparation (either finely or coarsely ground were used for NIR analyses. Spectra of FBS were treated with different mathematic pretreatments before being used to build models between the spectral information and fat (7.71%–30.89% or moisture (17.39%–32.65% content in FBS. Finely ground samples may lead to slightly more robust PLS models, but the particle sizes of ground FBS samples did not seriously affect the predictability of the models with appropriate mathematical treatments. The fat and moisture content in FBS predicted by FT-NIR methods had very good correlation with their values determined via traditional methods (fat, R2=0.965; moisture, R2=0.983, which clearly indicated that FT-NIR methods could be used as an effective tool for rapid determination of fat and moisture content in FBS.

  4. China Refrigerator Information Label: Specification Development and Potential Impact

    In the last five years, China's refrigerator market has grown rapidly, and now urban markets are showing signs of saturation, with ownership rates in urban households reaching 92%. Rural markets continue to grow from a much lower base. As a result of this growth, the Chinese government in 2006 decided to revise the refrigerator standards and its associated efficiency grades for the mandatory energy information label. In the Chinese standards process, the efficiency grades for the information label are tied to the minimum standards. Work on the minimum standards revision began in 2006 and continued through the first half of 2007, when the draft standard was completed under the direction of the China National Institute of Standardization (CNIS). Development of the information label grades required consideration of stakeholder input, continuity with the previous grade classification, ease of implementation, and potential impacts on the market. In this process, CLASP, with the support of METI/IEEJ, collaborated with CNIS to develop the efficiency grades, providing technical input to the process, comment and advice on particular technical issues, and evaluation of the results. After three months of effort and three drafts of the final grade specifications, this work was completed. In addition, in order to effectively evaluate the impact of the label on China's market, CLASP further provided assistance to CNIS to collect data on both the efficiency distribution and product volume distribution of refrigerators on the market. The new information label thresholds to be implemented in 2008 maintain the approach first adopted in 2005 of establishing efficiency levels relative to the minimum standard, but increased the related required efficiency levels by 20% over those established in 2003 and implemented in 2005. The focus of improvement was on the standard refrigerator/freezer (class 5), which constitutes the bulk of the Chinese market. Indeed, the new

  5. Development and Validation of a Lateral Flow Immunoassay for Rapid Detection of NDM-Producing Enterobacteriaceae. (United States)

    Boutal, Hervé; Naas, Thierry; Devilliers, Karine; Oueslati, Saoussen; Dortet, Laurent; Bernabeu, Sandrine; Simon, Stéphanie; Volland, Hervé


    The global spread of carbapenemase-producing Enterobacteriaceae (CPE) that are often resistant to most, if not all, classes of antibiotics is a major public health concern. The NDM-1 carbapenemase is among the most worrisome carbapenemases given its rapid worldwide spread. We have developed and evaluated a lateral flow immunoassay (LFIA) (called the NDM LFIA) for the rapid and reliable detection of NDM-like carbapenemase-producing Enterobacteriaceae from culture colonies. We evaluated the NDM LFIA using 175 reference enterobacterial isolates with characterized β-lactamase gene content and 74 nonduplicate consecutive carbapenem-resistant clinical isolates referred for expertise to the French National Reference Center (NRC) for Antibiotic Resistance during a 1-week period (in June 2016). The reference collection included 55 non-carbapenemase producers and 120 carbapenemase producers, including 27 NDM producers. All 27 NDM-like carbapenemase producers of the reference collection were correctly detected in less than 15 min by the NDM LFIA, including 22 strains producing NDM-1, 2 producing NDM-4, 1 producing NDM-5, 1 producing NDM-7, and 1 producing NDM-9. All non-NDM-1 producers gave a negative result with the NDM LFIA. No cross-reaction was observed with carbapenemases (VIM, IMP, NDM, KPC, and OXA-48-like), extended-spectrum β-lactamases (ESBLs) (TEM, SHV, and CTX-M), AmpCs (CMY-2, DHA-2, and ACC-1), and oxacillinases (OXA-1, -2, -9, and -10). Similarly, among the 74 referred nonduplicate consecutive clinical isolates, all 7 NDM-like producers were identified. Overall, the sensitivity and specificity of the assay were 100% for NDM-like carbapenemase detection with strains cultured on agar. The NDM LFIA was efficient, rapid, and easy to implement in the routine workflow of a clinical microbiology laboratory for the confirmation of NDM-like carbapenemase-producing Enterobacteriaceae .

  6. Development of a rapid dipstick with latex immunochromatographic assay (DLIA for diagnosis of schistosomiasis japonica

    Directory of Open Access Journals (Sweden)

    Lu Shao-Hong


    Full Text Available Abstract Background Schistosomiasis japonica (schistosomiasis is a zoonosis that can seriously affect human health. At present, the immunodiagnostic assays for schistosomiasis detection are time-consuming and require well-trained personnel and special instruments, which can limit their use in the field. Thus, there is a pressing need for a simple and rapid immunoassay to screen patients on a large scale. In this study, we developed a novel rapid dipstick with latex immunochromatographic assay (DLIA to detect anti-Schisaosoma japonicum antibodies in human serum. Results Using latex microspheres as a color probe, DLIA was established to test standard positive and negative sera, in comparison with the classical enzyme-linked immunosorbent assay (ELISA. The sensitivity and specificity of DLIA were 95.10% (97/102 and 94.91% (261/275, respectively. The cross-reaction rates with clonorchiosis, intestinal nematodes, Angiostrongylus cantonensis and paragonimiasis were 0, 0, 0 and 42.11% respectively. All the results showed no significant difference to the ELISA. In field tests, 333 human serum samples from an endemic area were tested with DLIA, and compared with ELISA and Kato-Katz method. There was no significant difference between DLIA and ELISA on positive and negative rates of detection; however, significant differences existed between DLIA and Kato-Katz method, and between ELISA and Kato-Katz method. The kappa value between DLIA and ELISA was 0.90. Conclusions This is the first study in which DLIA was used to detect anti-Schistosoma japonicum antibody. The results show that DLIA is a simple, rapid, convenient, sensitive and specific assay for the diagnosis of schistosomiasis and is therefore very suitable for large-scale field applications and clinical detection.

    Full Text Available Bus Rapid Transit (BRT has increasingly become an attractive urban transit alternative in many Asian developing cities due to its cost-effective and flexible implementation. However, it still seems to be difficult to introduce BRT to these cities because almost all of their city structures have been developed under solely a road transport development city plan and weakness of land use control gives rise to many problems, such as urban sprawl, traffic congestion, and air pollution. The purpose of this study was to introduce several strategies to support BRT implementation in Asian developing cities, such as a strategy to appropriately integrate the paratransit system into BRT system as being a feeder along a BRT corridor to supply demand. These proposed strategies were evaluated by applying demand forecasting and emission models to the BRT project plan of Bangkok Metropolitan Administration (BMA in Thailand. It was demonstrated that the proposed strategies could effectively improve the BRT ridership, traffic conditions, and air pollution emission of the entire system in Bangkok. This study could be further extended to include strategy recommendation if a BRT system were to be introduced to other Asian developing cities.

    Full Text Available Abstract Background Smoking, alcohol drinking and cannabis use ("risk behaviors" are often initiated at a young age but few epidemiological studies have assessed their joined prevalence in children in developing countries. This study aims at examining the joint prevalence of these behaviors in adolescents in the Seychelles, a rapidly developing country in the Indian Ocean. Methods Cross-sectional survey in a representative sample of secondary school students using an anonymous self-administered questionnaire (Global Youth Tobacco Survey. The questionnaire was completed by 1,321 (92% of 1,442 eligible students aged 11 to 17 years. Main variables of interest included smoking cigarettes on ≥1 day in the past 30 days; drinking any alcohol beverage on ≥1 day in the past 30 days and using cannabis at least once in the past 12 months. Results In boys and girls, respectively, prevalence (95% CI was 30% (26–34/21% (18–25 for smoking, 49% (45–54/48% (43–52 for drinking, and 17% (15–20/8% (6–10 for cannabis use. The prevalence of all these behaviors increased with age. Smokers were two times more likely than non-smokers to drink and nine times more likely to use cannabis. Drinkers were three times more likely than non-drinkers to smoke or to use cannabis. Comparison of observed versus expected frequencies of combination categories demonstrated clustering of these risk behaviors in students (P Conclusion Smoking, drinking and cannabis use were common and clustered among adolescents of a rapidly developing country. These findings stress the need for early and integrated prevention programs.

  9. Development of field-based separations for the rapid identification of uranium and plutonium

    Energy Technology Data Exchange (ETDEWEB)

    Mertz, Carol J.; Kaminski, Michael D.; Shkrob, Ilya A.; Kalensky, Michael; Sullivan, Vivian S.; Tsai, Yifen


    The development of rapid, radioanalytical techniques to separate uranium and plutonium from complex, field samples are needed for the timely and accurate determination of nuclear material origin, and processing activities. Widespread use of nuclear power and technology in the world has increased demands on analytical laboratories from the monitoring of numerous low-level, environmental samples with variable compositions. Environmental sampling has proven to be one of the strongest technical measures for detecting nuclear material and activities. With the increase in sampling demands, new technologies must offer improvements such as automation, high throughput, reproducible chemical separations, short analysis times, and reduced costs to be effective. We have been developing a portable, separations system for uranium (U) and plutonium (Pu) separations based upon selective extraction of target elements using an extraction chromatographic resin which would allow for simple and fast identifcation when coupled with the appropriate sample digestor and detection systems. The microfluidic design minimizes elution volumes and concentrates the elements of interest in a purified stream. Flowsheet development and testing was demonstrated on a single, micro-column system with an acidified, iron, uranium, and plutonium nitrate stream. The recovery of Pu was optimized by examining various reducing agents at different concentrations for rapid, quantitative recovery from the flow-through design. Quantitative recovery and high selectivity of U and Pu was achieved in the appropriate stripping stages and provided purified and concentrated U and Pu streams. The microfluidic system suggests automation in a small, footprint unit while exploiting the in-line processing of extraction chromatographic resins as the primary means of concentrating the radionuclides from the raw acidic feed and separating the elements into purified streams.

  11. Controlled precipitation for enhanced dissolution rate of flurbiprofen: development of rapidly disintegrating tablets. (United States)

    Essa, Ebtessam A; Elmarakby, Amira O; Donia, Ahmed M A; El Maghraby, Gamal M


    The aim of this work was to investigate the potential of controlled precipitation of flurbiprofen on solid surface, in the presence or absence of hydrophilic polymers, as a tool for enhanced dissolution rate of the drug. The work was extended to develop rapidly disintegrated tablets. This strategy provides simple technique for dissolution enhancement of slowly dissolving drugs with high scaling up potential. Aerosil was dispersed in ethanolic solution of flurbiprofen in the presence and absence of hydrophilic polymers. Acidified water was added as antisolvent to produce controlled precipitation. The resultant particles were centrifuged and dried at ambient temperature before monitoring the dissolution pattern. The particles were also subjected to FTIR spectroscopic, X-ray diffraction and thermal analyses. The FTIR spectroscopy excluded any interaction between flurbiprofen and excipients. The thermal analysis reflected possible change in the crystalline structure and or crystal size of the drug after controlled precipitation in the presence of hydrophilic polymers. This was further confirmed by X-ray diffraction. The modulation in the crystalline structure and size was associated with a significant enhancement in the dissolution rate of flurbiprofen. Optimum formulations were successfully formulated as rapidly disintegrating tablet with subsequent fast dissolution. Precipitation on a large solid surface area is a promising strategy for enhanced dissolution rate with the presence of hydrophilic polymers during precipitation process improving the efficiency.

  12. Evaluation of urban sprawl and urban landscape pattern in a rapidly developing region. (United States)

    Lv, Zhi-Qiang; Dai, Fu-Qiang; Sun, Cheng


    Urban sprawl is a worldwide phenomenon happening particularly in rapidly developing regions. A study on the spatiotemporal characteristics of urban sprawl and urban pattern is useful for the sustainable management of land management and urban land planning. The present research explores the spatiotemporal dynamics of urban sprawl in the context of a rapid urbanization process in a booming economic region of southern China from 1979 to 2005. Three urban sprawl types are distinguished by analyzing overlaid urban area maps of two adjacent study years which originated from the interpretation of remote sensed images and vector land use maps. Landscape metrics are used to analyze the spatiotemporal pattern of urban sprawl for each study period. Study results show that urban areas have expanded dramatically, and the spatiotemporal landscape pattern configured by the three sprawl types changed obviously. The different sprawl type patterns in five study periods have transformed significantly, with their proportions altered both in terms of quantity and of location. The present research proves that urban sprawl quantification and pattern analysis can provide a clear perspective of the urbanization process during a long time period. Particularly, the present study on urban sprawl and sprawl patterns can be used by land use and urban planners.

  13. Development of a fluorescence-based sensor for rapid diagnosis of cyanide exposure. (United States)

    Jackson, Randy; Oda, Robert P; Bhandari, Raj K; Mahon, Sari B; Brenner, Matthew; Rockwood, Gary A; Logue, Brian A


    Although commonly known as a highly toxic chemical, cyanide is also an essential reagent for many industrial processes in areas such as mining, electroplating, and synthetic fiber production. The "heavy" use of cyanide in these industries, along with its necessary transportation, increases the possibility of human exposure. Because the onset of cyanide toxicity is fast, a rapid, sensitive, and accurate method for the diagnosis of cyanide exposure is necessary. Therefore, a field sensor for the diagnosis of cyanide exposure was developed based on the reaction of naphthalene dialdehyde, taurine, and cyanide, yielding a fluorescent β-isoindole. An integrated cyanide capture "apparatus", consisting of sample and cyanide capture chambers, allowed rapid separation of cyanide from blood samples. Rabbit whole blood was added to the sample chamber, acidified, and the HCN gas evolved was actively transferred through a stainless steel channel to the capture chamber containing a basic solution of naphthalene dialdehyde (NDA) and taurine. The overall analysis time (including the addition of the sample) was cyanide exposure. Most importantly, the sensor was 100% accurate in diagnosing cyanide poisoning for acutely exposed rabbits.

    Engineered scaffolds have been shown to be critical to various tissue engineering applications. This paper presents the development of a novel three-dimensional scaffold made from a mixture of chitosan microspheres (CMs) and poly(l-lactide) by means of the rapid freeze prototyping (RFP) technique. The CMs were used to encapsulate bovine serum albumin (BSA) and improve the scaffold mechanical properties. Experiments to examine the BSA release were carried out; the BSA release could be controlled by adjusting the crosslink degree of the CMs and prolonged after the CMs were embedded into the PLLA scaffolds, while the examination of the mechanical properties of the scaffolds illustrates that they depend on the ratio of CMs to PLLA in the scaffolds as well as the cryogenic temperature used in the RFP fabrication process. The chemical characteristics of the PLLA/chitosan scaffolds were evaluated by Fourier transform infrared (FTIR) spectroscopy. The morphological and pore structure of the scaffolds were also examined by scanning electron microscopy and micro-tomography. The results obtained show that the scaffolds have higher porosity and enhanced pore size distribution compared to those fabricated by the dispensing-based rapid prototyping technique. This study demonstrates that the novel scaffolds have not only enhanced porous structure and mechanical properties but also showed the potential to preserve the bioactivities of the biomolecules and to control the biomolecule distribution and release rate.

    Al Awar, Zeina; Kuziemsky, Craig


    Informal caregivers are playing an increasing role in community based care delivery. Research is needed that looks at the educational needs of informal caregivers as a precursor to HIT design to support community care delivery. A challenge is informal caregivers have very diverse educational needs. Personas are an approach to describe user characteristics as part of systems design and this approach could be used to understand and categorize the various educational needs of informal caregivers. This paper addresses this research need and provides a method for persona development and the identification of educational needs for informal caregivers.

    The study subjects are S. Korean NPP(Nuclear Power Plant) construction projects. Design, construction, operations companies have different nuclear power plant construction project structures, and each company has its own Information Management System. In this study, the end user developed an Information Management System early in the project, and developed a management structure that systematically integrates and interfaces with information in each lifecycle phase. The main perspective of Information Management is moving from the existent document-centric management to the data-centric management. To do so, we intend to integrate information with interfaces among systems. Integrated information management structure and management system are essential for an effective management of the lifecycle information of nuclear power plants that have a lifespan over as much as 80 years. The concept of integration management adopted by the defence, ocean industries or various PLM solution providers is important. Although the NPP project has application systems in each key lifecycle phase, it is more effective to develop and use PLIMS in consideration of the interface and compatibility of information among systems. As an initial study for development of that integrated information management structure, this study is building the system and has interfaced it with a design-stage system.

    Full Text Available The use of information and communication technology for self-education and self-development of adults is becoming a pressing issue of our time. This article is intended to explore the current status of this issue, especially considering the growing importance of self-education of adults, the popularity of information and communication technologies in contemporary society, their application in various phases of public life and the life of an individual. An issue of modern educational environment is becoming an «education for life». Modern types of education, such as non-formal and informal, acquire development and allow an adult to undertake continuing education. An adult acquires a certain maturity as a person, but in modern society its further development becomes relevant for the reason that the needs and interests of society are changing rapidly. It makes a person also change rapidly through his / her self-development. Due to which people change their worldview, motivations, beliefs, personal characteristics, corrects a look at the meaning of his existence. The rapid and rapid development of information and communication technologies helps to relieve stress from modern reality. Their framework is based on a circulated network on the Internet, which opens a huge opportunity for any user and satisfies almost every informational request of a modern person. In the article we observed what options modern Internet environment offers for self-learning and self-development of an adult, and how these propositions may correspond the question posed

  20. Anesthetics rapidly promote synaptogenesis during a critical period of brain development.

    Directory of Open Access Journals (Sweden)

    Mathias De Roo

    Full Text Available Experience-driven activity plays an essential role in the development of brain circuitry during critical periods of early postnatal life, a process that depends upon a dynamic balance between excitatory and inhibitory signals. Since general anesthetics are powerful pharmacological modulators of neuronal activity, an important question is whether and how these drugs can affect the development of synaptic networks. To address this issue, we examined here the impact of anesthetics on synapse growth and dynamics. We show that exposure of young rodents to anesthetics that either enhance GABAergic inhibition or block NMDA receptors rapidly induce a significant increase in dendritic spine density in the somatosensory cortex and hippocampus. This effect is developmentally regulated; it is transient but lasts for several days and is also reproduced by selective antagonists of excitatory receptors. Analyses of spine dynamics in hippocampal slice cultures reveals that this effect is mediated through an increased rate of protrusions formation, a better stabilization of newly formed spines, and leads to the formation of functional synapses. Altogether, these findings point to anesthesia as an important modulator of spine dynamics in the developing brain and suggest the existence of a homeostatic process regulating spine formation as a function of neural activity. Importantly, they also raise concern about the potential impact of these drugs on human practice, when applied during critical periods of development in infants.

  1. Acceptability of an intelligent wireless sensor system for the rapid detection of health issues: findings among home-dwelling older adults and their informal caregivers. (United States)

    Cohen, Christine; Kampel, Thomas; Verloo, Henk


    Aging at home rather than in an institution is now considered the gold standard. Public health figures document an important demographic transition to an increasingly elderly society. At the same time, this is accompanied by the emergence of significant numbers of innovative technologies to help and support home-dwelling older adults in declining health who wish to remain at home. To explore the acceptability of intelligent wireless sensor system (IWSS) among home-dwelling older adults in rapidly detecting their health issues. Data were sourced from a pilot 3-month randomized clinical trial that involved 34 older patients in the experimental group (EG) using an IWSS to rapidly detect falls and other health issues at home. The effectiveness of the IWSS was assessed by comparing it to participants' functional and cognitive status, as measured both before and after the trial. The Resident Assessment Instrument for Home Care, Confusion Assessment Method, Cognitive Performance Scale, Geriatric Depression Scale, and Informed Questionnaire on Cognitive Decline in the Elderly were used for the assessments. Acceptability of the IWSS was explored at the end of the study. Both older adults and their informal caregivers considered the performance and usefulness of the IWSS intervention to be low to moderate. A majority of the participants were unsatisfied with its ease of use and found multiple obstacles in using and having an intention to use the IWSS. However, their informal caregivers were more satisfied with the program and gave higher scores for usefulness, ease of use, and intention to use IWSS technology. The IWSS displayed low-to-moderate acceptability among the older participants and their informal caregivers. We recommend improving and clarifying several components in the IWSS for the development of a design that is user-centered.

  2. Diagnosis and treatment of familial cherubism characterized by early onset and rapid development. (United States)

    Mortellaro, Carmen; Bello, Lucilla; Lucchina, Alberta Greco; Pucci, Angela


    Cherubism is a benign maxillary bone dysplasia of childhood, usually showing an autosomically dominant inheritance with variable penetrance and spontaneously resolving after puberty. Only maxillary bones are affected and develop pseudocystic osteolytic lesions. This article presents an early and rapidly evolving familial case of cherubism. The 3-year-old child underwent conservative curettage of lesions, with a conservative approach that allowed a normal permanent dentition in adolescence. Family history revealed that the father had been treated for similar lesions between 14 and 21 years of age, but the late treatment caused edentulism. In conclusion, although cherubism represents a benign and localized maxillary dysplasia, it requires prompt surgical but conservative treatment and careful follow-up to avoid permanent lesions, that is, malocclusion and/or edentulism.

  3. Rapid Development and Use of a Nationwide Training Program for Cholera Management, Haiti, 2010 (United States)

    Lynch, Michael; Lambert, Yves; Sobel, Jeremy; Domerçant, Jean W.; Khan, Azharul


    When epidemic cholera appeared in Haiti in October 2010, the medical community there had virtually no experience with the disease and needed rapid training as the epidemic spread throughout the country. We developed a set of training materials specific to Haiti and launched a cascading training effort. Through a training-of-trainers course in November 14–15, 2010, and department-level training conducted in French and Creole over the following 3 weeks, 521 persons were trained and equipped to further train staff at the institutions where they worked. After the training, the hospitalized cholera patients’ case-fatality rate dropped from 4% to <2% by mid-December and was <1% by January 2011. Continuing in-service training, monitoring and evaluation, and integration of cholera management into regular clinical training will help sustain this success. PMID:22099112

  4. Development of Middle Stone Age innovation linked to rapid climate change. (United States)

    Ziegler, Martin; Simon, Margit H; Hall, Ian R; Barker, Stephen; Stringer, Chris; Zahn, Rainer


    The development of modernity in early human populations has been linked to pulsed phases of technological and behavioural innovation within the Middle Stone Age of South Africa. However, the trigger for these intermittent pulses of technological innovation is an enigma. Here we show that, contrary to some previous studies, the occurrence of innovation was tightly linked to abrupt climate change. Major innovational pulses occurred at times when South African climate changed rapidly towards more humid conditions, while northern sub-Saharan Africa experienced widespread droughts, as the Northern Hemisphere entered phases of extreme cooling. These millennial-scale teleconnections resulted from the bipolar seesaw behaviour of the Atlantic Ocean related to changes in the ocean circulation. These conditions led to humid pulses in South Africa and potentially to the creation of favourable environmental conditions. This strongly implies that innovational pulses of early modern human behaviour were climatically influenced and linked to the adoption of refugia.

  5. [Development and scientific rationale for a universal index for rapid assessment of readability]. (United States)

    Teksheva, L M


    The hygienic regulations of academic books, including teachware, for children and adolescents necessitate the performance of special studies to assess their readability by the unified procedure that would suggest a visual response while reading. This study has developed and warranted a universal readability index by the velocity of reading. There are significant regression correlations between the velocity of reading as the readability index and the degree of tiredness, detected by various visual functions. The parameters of accommodation and adaptive properties of the eye are most sensitive to visual load on reading. Reading velocity as an indicator of readability of illogical texts may be used as a rapid method under laboratory and natural conditions to determine the action of various textual loads on the visual system.

  7. Trading certainty for speed - how much uncertainty are decisionmakers and guideline developers willing to accept when using rapid reviews: an international survey. (United States)

    Wagner, Gernot; Nussbaumer-Streit, Barbara; Greimel, Judith; Ciapponi, Agustín; Gartlehner, Gerald


    Decisionmakers and guideline developers demand rapid syntheses of the evidence when time sensitive evidence-informed decisions are required. A potential trade-off of such rapid reviews is that their results can have less reliability than results of systematic reviews that can lead to an increased risk of making incorrect decisions or recommendations. We sought to determine how much incremental uncertainty about the correctness of an answer guideline developers and health policy decisionmakers are willing to accept in exchange for a rapid evidence-synthesis. Employing a purposive sample, we conducted an international web-based, anonymous survey of decisionmakers and guideline developers. Based on a clinical treatment, a public health, and a clinical prevention scenario, participants indicated the maximum risk of getting an incorrect answer from a rapid review that they would be willing to accept. We carefully reviewed data and performed descriptive statistical analyses. In total, 325 (58.5%) of 556 participants completed our survey and were eligible for analysis. The median acceptable incremental risk for getting an incorrect answer from a rapid review across all three scenarios was 10.0% (interquartile range [IQR] 5.0-15.0). Acceptable risks were similar for the clinical treatment (n = 313, median 10.0% [IQR 5.0-15.0]) and the public health scenarios (n = 320, median 10.0% [IQR 5.0-15.0]) and lower for the clinical prevention scenario (n = 312, median 6.5% [IQR 5.0-10.5]). Findings suggest that decisionmakers are willing to accept some trade-off in validity in exchange for a rapid review. Nevertheless, they expect the validity of rapid reviews to come close to that of systematic reviews.

  9. Development of cross-priming amplification assays for rapid and sensitive detection of Aeromonas hydrophila. (United States)

    Meng, S; Wang, Y; Wang, Y; Liu, D; Ye, C


    Aeromonas hydrophila has been increasingly implicated as the aetiologic agent of various human diseases. Therefore, reliable laboratory detection and identification of this bacterium has become clinically and epidemiologically desirable. We developed a nearly instrument-free, simple molecular method for rapid detection of Aer. hydrophila using a cross-priming amplification (CPA) assay with the desA gene as the target. The desA gene is crucial for the survival and growth of Aer. hydrophila under iron starvation. The results can be visualized as colour changes without opening the reaction tubes. No false-positive results were observed for the 33 non-Aer. hydrophila strains tested to evaluate assay specificity. The limit of detection for Aer. hydrophila was approximately 200 copies of desA per reaction (on reference plasmids) and 5 × 10(3)  CFU g(-1) Aer. hydrophila in simulated human stool, which is the same sensitivity as a qPCR assay. The performance of the CPA assay was also evaluated with 100 stool specimens from diarrhoea patients and 40 environmental water samples. In conclusion, the simplicity, cost-effectiveness and nearly instrument-free platform of the CPA assay make it practical for use in primary care facilities and smaller clinical laboratories. Aeromonas hydrophila is a human pathogen that infects via exposed wounds or ingestion of contaminated water and food. In this study, a CPA-based PCR method was developed for specific, rapid, cost-effective detection of Aer. hydrophila, and the test results could be visualized without opening the reaction tubes. This is the first report on the application of the CPA method for the detection of Aer. hydrophila. This novel method could be practical for use in primary care facilities and smaller clinical laboratories. © 2015 The Society for Applied Microbiology.

    Plague is often fatal without prompt and appropriate treatment. It affects mainly poor and remote populations. Late diagnosis is one of the major causes of human death and spread of the disease, since it limits the effectiveness of control measures. We aimed to develop and assess a rapid diagnostic test (RDT) for plague. We developed a test that used monoclonal antibodies to the F1 antigen of Yersinia pestis. Sensitivity and specificity were assessed with a range of bacterial cultures and clinical samples, and compared with findings from available ELISA and bacteriological tests for plague. Samples from patients thought to have plague were tested with the RDT in the laboratory and by health workers in 26 pilot sites in Madagascar. The RDT detected concentrations of F1 antigen as low as 0.5 ng/mL in up to 15 min, and had a shelf life of 21 days at 60 degrees C. Its sensitivity and specificity were both 100%. RDT detected 41.6% and 31% more positive clinical specimens than did bacteriological methods and ELISA, respectively. The agreement rate between tests done at remote centres and in the laboratory was 89.8%. With the combination of bacteriological methods and F1 ELISA as reference standard, the positive and negative predictive values of the RDT were 90.6% and 86.7%, respectively. Our RDT is a specific, sensitive, and reliable test that can easily be done by health workers at the patient's bedside, for the rapid diagnosis of pneumonic and bubonic plague. This test will be of key importance for the control of plague in endemic countries.

  11. Using aerial photography to estimate riparian zone impacts in a rapidly developing river corridor. (United States)

    Owers, Katharine A; Albanese, Brett; Litts, Thomas


    Riparian zones are critical for protecting water quality and wildlife, but are often impacted by human activities. Ongoing threats and uncertainty about the effectiveness of buffer regulations emphasize the importance of monitoring riparian buffers through time. We developed a method to rapidly categorize buffer width and landuse attributes using 2007 leaf-on aerial photography and applied it to a 65 km section of the Toccoa River in north Georgia. We repeated our protocol using 1999 leaf-off aerial photographs to assess the utility of our approach for monitoring. Almost half (45%) of the length of the Toccoa River was bordered by buffers less than 50 ft wide in 2007, with agricultural and built-up lands having the smallest buffers. The percentage of river length in each buffer width category changed little between 1999 and 2007, but we did detect a 5% decrease in agricultural land use, a corresponding increase in built-up land use, and an additional 149 buildings within 100 ft of the river. Field verification indicated that our method overestimated buffer widths and forested land use and underestimated built-up land use and the number of buildings within 100 ft of the river. Our methodology can be used to rapidly assess the status of riparian buffers. Including supplemental data (e.g., leaf-off imagery, road layers) will allow detection of the fine-scale impacts underestimated in our study. Our results on the Toccoa River reflect historic impacts, exemptions and variances to regulations, and the ongoing threat of vacation home development. We recommend additional monitoring, improvements in policy, and efforts to increase voluntary protection and restoration of stream buffers.

  12. The process of developing audiovisual patient information: challenges and opportunities. (United States)

    Hutchison, Catherine; McCreaddie, May


    The aim of this project was to produce audiovisual patient information, which was user friendly and fit for purpose. The purpose of the audiovisual patient information is to inform patients about randomized controlled trials, as a supplement to their trial-specific written information sheet. Audiovisual patient information is known to be an effective way of informing patients about treatment. User involvement is also recognized as being important in the development of service provision. The aim of this paper is (i) to describe and discuss the process of developing the audiovisual patient information and (ii) to highlight the challenges and opportunities, thereby identifying implications for practice. A future study will test the effectiveness of the audiovisual patient information in the cancer clinical trial setting. An advisory group was set up to oversee the project and provide guidance in relation to information content, level and delivery. An expert panel of two patients provided additional guidance and a dedicated operational team dealt with the logistics of the project including: ethics; finance; scriptwriting; filming; editing and intellectual property rights. Challenges included the limitations of filming in a busy clinical environment, restricted technical and financial resources, ethical needs and issues around copyright. There were, however, substantial opportunities that included utilizing creative skills, meaningfully involving patients, teamworking and mutual appreciation of clinical, multidisciplinary and technical expertise. Developing audiovisual patient information is an important area for nurses to be involved with. However, this must be performed within the context of the multiprofessional team. Teamworking, including patient involvement, is crucial as a wide variety of expertise is required. Many aspects of the process are transferable and will provide information and guidance for nurses, regardless of specialty, considering developing this

  14. a Cultural Landscape Information System Developed with Open Source Tools (United States)

    Chudyk, C.; Müller, H.; Uhler, M.; Würriehausen, F.


    Since 2010, the state of Rhineland-Palatinate in Germany has developed a cultural landscape information system as a process to secure and further enrich aggregate data about its cultural assets. In an open dialogue between governing authorities and citizens, the intention of the project is an active cooperation of public and private actors. A cultural landscape information system called KuLIS was designed as a web platform, combining semantic wiki software with a geographic information system. Based on data sets from public administrations, the information about cultural assets can be extended and enhanced by interested participants. The developed infrastructure facilitates local information accumulation through a crowdsourcing approach. This capability offers new possibilities for e-governance and open data developments. The collaborative approach allows governing authorities to manage and supervise official data, while public participation enables affordable information acquisition. Gathered cultural heritage information can provide incentives for touristic valorisation of communities or concepts for strengthening regional identification. It can also influence political decisions in defining significant cultural regions worth of protecting from industrial influences. The presented cultural landscape information allows citizens to influence the statewide development of cultural landscapes in a democratic way.

  19. Rapid-X - An FPGA Development Toolset Using a Custom Simulink Library for MTCA.4 Modules (United States)

    Prędki, Paweł; Heuer, Michael; Butkowski, Łukasz; Przygoda, Konrad; Schlarb, Holger; Napieralski, Andrzej


    The recent introduction of advanced hardware architectures such as the Micro Telecommunications Computing Architecture (MTCA) caused a change in the approach to implementation of control schemes in many fields. The development has been moving away from traditional programming languages ( C/C++), to hardware description languages (VHDL, Verilog), which are used in FPGA development. With MATLAB/Simulink it is possible to describe complex systems with block diagrams and simulate their behavior. Those diagrams are then used by the HDL experts to implement exactly the required functionality in hardware. Both the porting of existing applications and adaptation of new ones require a lot of development time from them. To solve this, Xilinx System Generator, a toolbox for MATLAB/Simulink, allows rapid prototyping of those block diagrams using hardware modelling. It is still up to the firmware developer to merge this structure with the hardware-dependent HDL project. This prevents the application engineer from quickly verifying the proposed schemes in real hardware. The framework described in this article overcomes these challenges, offering a hardware-independent library of components that can be used in Simulink/System Generator models. The components are subsequently translated into VHDL entities and integrated with a pre-prepared VHDL project template. Furthermore, the entire implementation process is run in the background, giving the user an almost one-click path from control scheme modelling and simulation to bit-file generation. This approach allows the application engineers to quickly develop new schemes and test them in real hardware environment. The applications may range from simple data logging or signal generation ones to very advanced controllers. Taking advantage of the Simulink simulation capabilities and user-friendly hardware implementation routines, the framework significantly decreases the development time of FPGA-based applications.

  20. Development of Information Ethics in Library and Information Science in Taiwan

    Directory of Open Access Journals (Sweden)

    Chi-Chuan Wu


    Full Text Available We are facing a growing concern on the social and ethical issues that comes from the increasing reliance on the information technology in information era. Findings of past research point out that Information Ethics is an important issue, and should become a mandatory course for Library and Information Science education. However, the field of Library and Information Science is still developing to value the concept of information ethics and surrounding issues. This article introduces the origin and definitions of information ethics, and analyzes its development in education and research in the field of Library and Information Science in Taiwan over the sixteen years from 1994-2010. We hope to arrive at a further understanding on the issues of “information ethics” and to establish conformity of using the term “information ethics”. In addition, we also hope that the results of the study will serve as a reference for educators and researchers in promoting information ethics. Finally, we propose suggestions for the planning of teaching and curriculum direction. [Article content in Chinese

  1. Ion torrent personal genome machine sequencing for genomic typing of Neisseria meningitidis for rapid determination of multiple layers of typing information. (United States)

    Vogel, Ulrich; Szczepanowski, Rafael; Claus, Heike; Jünemann, Sebastian; Prior, Karola; Harmsen, Dag


    Neisseria meningitidis causes invasive meningococcal disease in infants, toddlers, and adolescents worldwide. DNA sequence-based typing, including multilocus sequence typing, analysis of genetic determinants of antibiotic resistance, and sequence typing of vaccine antigens, has become the standard for molecular epidemiology of the organism. However, PCR of multiple targets and consecutive Sanger sequencing provide logistic constraints to reference laboratories. Taking advantage of the recent development of benchtop next-generation sequencers (NGSs) and of BIGSdb, a database accommodating and analyzing genome sequence data, we therefore explored the feasibility and accuracy of Ion Torrent Personal Genome Machine (PGM) sequencing for genomic typing of meningococci. Three strains from a previous meningococcus serogroup B community outbreak were selected to compare conventional typing results with data generated by semiconductor chip-based sequencing. In addition, sequencing of the meningococcal type strain MC58 provided information about the general performance of the technology. The PGM technology generated sequence information for all target genes addressed. The results were 100% concordant with conventional typing results, with no further editing being necessary. In addition, the amount of typing information, i.e., nucleotides and target genes analyzed, could be substantially increased by the combined use of genome sequencing and BIGSdb compared to conventional methods. In the near future, affordable and fast benchtop NGS machines like the PGM might enable reference laboratories to switch to genomic typing on a routine basis. This will reduce workloads and rapidly provide information for laboratory surveillance, outbreak investigation, assessment of vaccine preventability, and antibiotic resistance gene monitoring.

  2. AIBench: a rapid application development framework for translational research in biomedicine. (United States)

    Glez-Peña, D; Reboiro-Jato, M; Maia, P; Rocha, M; Díaz, F; Fdez-Riverola, F


    Applied research in both biomedical discovery and translational medicine today often requires the rapid development of fully featured applications containing both advanced and specific functionalities, for real use in practice. In this context, new tools are demanded that allow for efficient generation, deployment and reutilization of such biomedical applications as well as their associated functionalities. In this context this paper presents AIBench, an open-source Java desktop application framework for scientific software development with the goal of providing support to both fundamental and applied research in the domain of translational biomedicine. AIBench incorporates a powerful plug-in engine, a flexible scripting platform and takes advantage of Java annotations, reflection and various design principles in order to make it easy to use, lightweight and non-intrusive. By following a basic input-processing-output life cycle, it is possible to fully develop multiplatform applications using only three types of concepts: operations, data-types and views. The framework automatically provides functionalities that are present in a typical scientific application including user parameter definition, logging facilities, multi-threading execution, experiment repeatability and user interface workflow management, among others. The proposed framework architecture defines a reusable component model which also allows assembling new applications by the reuse of libraries from past projects or third-party software.

  3. Isolation, amplification and characterization of foodborne pathogen disease bacteria gene for rapid kit test development (United States)

    Nurjayadi, M.; Santoso, I.; Kartika, I. R.; Kurniadewi, F.; Saamia, V.; Sofihan, W.; Nurkhasanah, D.


    There is a lot of public concern over food safety. Food-safety cases recently, including many food poisoning cases in both the developed and developing countries, considered to be the national security threats which involved police investigation. Quick and accurate detection methods are needed to handle the food poisoning cases with a big number of sufferers at the same time. Therefore, the research is aimed to develop a specific, sensitive, and rapid result molecular detection tool for foodborne pathogen bacteria. We, thus, propose genomic level approach with Polymerase Chain Reaction. The research has successfully produced a specific primer to perform amplification to fim-C S. typhi, E. coli, and pef Salmonella typhimurium genes. The electrophoresis result shows that amplification products are 95 base pairs, 121 base pairs, and 139 base pairs; and all three genes are in accordance with the size of the in silico to third genes bacteria. In conclusion, the research has been successfully designed a specific detection tool to three foodborne pathogen bacteria genes.

  4. Evaluation of Proteus as a Tool for the Rapid Development of Models of Hydrologic Systems (United States)

    Weigand, T. M.; Farthing, M. W.; Kees, C. E.; Miller, C. T.


    Models of modern hydrologic systems can be complex and involve a variety of operators with varying character. The goal is to implement approximations of such models that are both efficient for the developer and computationally efficient, which is a set of naturally competing objectives. Proteus is a Python-based toolbox that supports prototyping of model formulations as well as a wide variety of modern numerical methods and parallel computing. We used Proteus to develop numerical approximations for three models: Richards' equation, a brine flow model derived using the Thermodynamically Constrained Averaging Theory (TCAT), and a multiphase TCAT-based tumor growth model. For Richards' equation, we investigated discontinuous Galerkin solutions with higher order time integration based on the backward difference formulas. The TCAT brine flow model was implemented using Proteus and a variety of numerical methods were compared to hand coded solutions. Finally, an existing tumor growth model was implemented in Proteus to introduce more advanced numerics and allow the code to be run in parallel. From these three example models, Proteus was found to be an attractive open-source option for rapidly developing high quality code for solving existing and evolving computational science models.

  5. Late winter feeding stimulates rapid spring development of carniolan honey bee colonies (Apis mellifera carnica

    Directory of Open Access Journals (Sweden)

    Zlatko Puškadija


    Full Text Available Unfavourable weather conditions after the queen starts with intensive oviposition during early spring may cause an imbalance in the division of tasks among worker bees in the bee colony. This can lead to slow spring development and poor exploitation of the main spring nectar flows. In order to accelerate the spring development, it is necessary, as a technological measure, to feed supplemental candy to bee colonies. In this research, the necessity of supplemental feeding, as well as the composition of candy (pollen and protein substitute were analysed. Three groups of ten bee colonies each were formed - the control, unfed group, pollen candy fed and protein substitute candy fed. In the period from 22/02/2016 and 04/04/2016 three control measurements were performed during which the number of bees, the number of brood cells and weight of the bee colonies were determined. The research has shown that supplemental feeding of the bee colony in late winter in order to encourage the rapid spring development is justified. Namely, at the final measurements in April, the results showed differences between groups. The treated colonies had higher net hive weight, a greater number of bees and statistically significantly more brood cells. The results of this study confirm that the technological measure of supplemental feeding in late winter should be performed on all commercial apiaries for the production of honey, pollen, royal jelly, queen bees and bee venom.

  6. Overcoming challenges to initiating cell therapy clinical trials in rapidly developing countries: India as a model. (United States)

    Viswanathan, Sowmya; Rao, Mahendra; Keating, Armand; Srivastava, Alok


    Increasingly, a number of rapidly developing countries, including India, China, Brazil, and others, are becoming global hot spots for the development of regenerative medicine applications, including stem cell-based therapies. Identifying and overcoming regulatory and translational research challenges and promoting scientific and ethical clinical trials with cells will help curb the growth of stem cell tourism for unproven therapies. It will also enable academic investigators, local regulators, and national and international biotechnology and biopharmaceutical companies to accelerate stem cell-based clinical research that could lead to effective innovative treatments in these regions. Using India as a model system and obtaining input from regulators, clinicians, academics, and industry representatives across the stem cell field in India, we reviewed the role of key agencies and processes involved in this field. We have identified areas that need attention and here provide solutions from other established and functioning models in the world to streamline and unify the regulatory and ethics approval processes for cell-based therapies. We also make recommendations to check the growth and functioning of clinics offering unproven treatments. Addressing these issues will remove considerable hurdles to both local and international investigators, accelerate the pace of research and development, and create a quality environment for reliable products to emerge. By doing so, these countries would have taken one important step to move to the forefront of stem cell-based therapeutics.

  9. The Athena Breast Health Network: developing a rapid learning system in breast cancer prevention, screening, treatment, and care. (United States)

    Elson, Sarah L; Hiatt, Robert A; Anton-Culver, Hoda; Howell, Lydia P; Naeim, Arash; Parker, Barbara A; Van't Veer, Laura J; Hogarth, Michael; Pierce, John P; Duwors, Robert J; Hajopoulos, Kathy; Esserman, Laura J


    The term breast cancer covers many different conditions, whose clinical course ranges from indolent to aggressive. However, current practice in breast cancer prevention and care, and in breast cancer epidemiology, does not take into account the heterogeneity of the disease. A comprehensive understanding of the etiology and progression of different breast cancer subtypes would enable a more patient-centered approach to breast health care: assessing an individual's risk of getting specific subtypes of the disease, providing risk-based screening and prevention recommendations, and, for those diagnosed with the disease, tailored treatment options based on risk and timing of progression and mortality. The Athena Breast Health Network is an initiative of the five University of California medical and cancer centers to prototype this approach and to enable the development of a rapid learning system-connecting risk and outcome information from a heterogeneous patient population in real time and using new knowledge from research to continuously improve the quality of care. The Network is based on integrating clinical and research processes to create a comprehensive approach to accelerating patient-centered breast health care. Since its inception in 2009, the Network has developed a multi-site, transdisciplinary collaboration that enables the learning system. The five-campus collaboration has implemented a shared informatics platform, standardized electronic patient intake questionnaires, and common biospecimen protocols, as well as new clinical programs and multi-center research projects. The Athena Breast Health Network can serve as a model of a rapid learning system that integrates epidemiologic, behavioral, and clinical research with clinical care improvements.

  10. The rapid bi-level exploration on the evolution of regional solar energy development (United States)

    Guan, Qing; An, Haizhong; Li, Huajiao; Hao, Xiaoqing


    As one of the renewable energy, solar energy is experiencing increased but exploratory development worldwide. The positive or negative influences of regional characteristics, like economy, production capacity and allowance policies, make them have uneven solar energy development. In this paper, we aim at quickly exploring the features of provincial solar energy development, and their concerns about solar energy. We take China as a typical case, and combine text mining and two-actor networks. We find that the classification of levels based on certain nodes and the amount of degree avoids missing meaningful information that may be ignored by global level results. Moreover, eastern provinces are hot focus for the media, western countries are key to bridge the networks and special administrative region has local development features; third, most focus points are more about the application than the improvement of material. The exploration of news provides practical information to adjust researches and development strategies of solar energy. Moreover, the bi-level exploration, which can also be expanded to multi-level, is helpful for governments or researchers to grasp more targeted and precise knowledge.

  11. Rapid development of microsatellite markers for Callosobruchus chinensis using Illumina paired-end sequencing.

    Directory of Open Access Journals (Sweden)

    Can-Xing Duan

    Full Text Available BACKGROUND: The adzuki bean weevil, Callosobruchus chinensis L., is one of the most destructive pests of stored legume seeds such as mungbean, cowpea, and adzuki bean, which usually cause considerable loss in the quantity and quality of stored seeds during transportation and storage. However, a lack of genetic information of this pest results in a series of genetic questions remain largely unknown, including population genetic structure, kinship, biotype abundance, and so on. Co-dominant microsatellite markers offer a great resolving power to determine these events. Here, we report rapid microsatellite isolation from C. chinensis via high-throughput sequencing. PRINCIPAL FINDINGS: In this study, 94,560,852 quality-filtered and trimmed reads were obtained for the assembly of genome using Illumina paired-end sequencing technology. In total, the genome with total length of 497,124,785 bp, comprising 403,113 high quality contigs was generated with de novo assembly. More than 6800 SSR loci were detected and a suit of 6303 primer pair sequences were designed and 500 of them were randomly selected for validation. Of these, 196 pair of primers, i.e. 39.2%, produced reproducible amplicons that were polymorphic among 8 C. chinensis genotypes collected from different geographical regions. Twenty out of 196 polymorphic SSR markers were used to analyze the genetic diversity of 18 C. chinensis populations. The results showed the twenty SSR loci were highly polymorphic among these populations. CONCLUSIONS: This study presents a first report of genome sequencing and de novo assembly for C. chinensis and demonstrates the feasibility of generating a large scale of sequence information and SSR loci isolation by Illumina paired-end sequencing. Our results provide a valuable resource for C. chinensis research. These novel markers are valuable for future genetic mapping, trait association, genetic structure and kinship among C. chinensis.

  19. Low-Cost Rapid Usability Testing: Its Application in Both Product Development and System Implementation. (United States)

    Kushniruk, Andre; Borycki, Elizabeth


    In recent years there has been considerable discussion around the need for certification and regulation of healthcare information technology (IT). In particular, the usability of the products being developed needs to be evaluated. This has included the application of standards designed to ensure the process of system development is user-centered and takes usability into consideration while a product is being developed. In addition to this, in healthcare, organizations in the United States and Europe have also addressed the need and requirement for product certification. However, despite these efforts there are continued reports of unusable and unsafe implementations. In this paper we discuss the need to not only include (and require) usability testing in the one-time development process of health IT products (such as EHRs), but we also argue for the need to additionally develop specific usability standards and requirements for usability testing during the implementation of vendor products (i.e. post product development) in healthcare settings. It is further argued that health IT products that may have been certified regarding their development process will still require application of usability testing in the process of implementing them in real hospital settings in order to ensure usability and safety. This is needed in order to ensure that the final result of both product development and implementation processes take into account and apply the latest usability principles and methods.

  20. Development of compact rapid charging power supply for capacitive energy storage in pulsed power drivers. (United States)

    Sharma, Surender Kumar; Shyam, Anurag


    High energy capacitor bank is used for primary electrical energy storage in pulsed power drivers. The capacitors used in these pulsed power drivers have low inductance, low internal resistance, and less dc life, so it has to be charged rapidly and immediately discharged into the load. A series resonant converter based 45 kV compact power supply is designed and developed for rapid charging of the capacitor bank with constant charging current up to 150 mA. It is short circuit proof, and zero current switching technique is used to commute the semiconductor switch. A high frequency resonant inverter switching at 10 kHz makes the overall size small and reduces the switching losses. The output current of the power supply is limited by constant on-time and variable frequency switching control technique. The power supply is tested by charging the 45 kV/1.67 μF and 15 kV/356 μF capacitor banks. It has charged the capacitor bank up to rated voltage with maximum charging current of 150 mA and the average charging rate of 3.4 kJ/s. The output current of the power supply is limited by reducing the switching frequency at 5 kHz, 3.3 kHz, and 1.7 kHz and tested with 45 kV/1.67 μF capacitor bank. The protection circuit is included in the power supply for over current, under voltage, and over temperature. The design details and the experimental testing results of the power supply for resonant current, output current, and voltage traces of the power supply with capacitive, resistive, and short circuited load are presented and discussed.

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside

  2. Evaluation of nine HIV rapid test kits to develop a national HIV testing algorithm in Nigeria

    Directory of Open Access Journals (Sweden)

    Orji Bassey


    Full Text Available Background: Non-cold chain-dependent HIV rapid testing has been adopted in many resource-constrained nations as a strategy for reaching out to populations. HIV rapid test kits (RTKs have the advantage of ease of use, low operational cost and short turnaround times. Before 2005, different RTKs had been used in Nigeria without formal evaluation. Between 2005 and 2007, a study was conducted to formally evaluate a number of RTKs and construct HIV testing algorithms. Objectives: The objectives of this study were to assess and select HIV RTKs and develop national testing algorithms. Method: Nine RTKs were evaluated using 528 well-characterised plasma samples. These comprised 198 HIV-positive specimens (37.5% and 330 HIV-negative specimens (62.5%, collected nationally. Sensitivity and specificity were calculated with 95% confidence intervals for all nine RTKs singly and for serial and parallel combinations of six RTKs; and relative costs were estimated. Results: Six of the nine RTKs met the selection criteria, including minimum sensitivity and specificity (both ≥ 99.0% requirements. There were no significant differences in sensitivities or specificities of RTKs in the serial and parallel algorithms, but the cost of RTKs in parallel algorithms was twice that in serial algorithms. Consequently, three serial algorithms, comprising four test kits (BundiTM, DetermineTM, Stat-Pak® and Uni-GoldTM with 100.0% sensitivity and 99.1% – 100.0% specificity, were recommended and adopted as national interim testing algorithms in 2007. Conclusion: This evaluation provides the first evidence for reliable combinations of RTKs for HIV testing in Nigeria. However, these RTKs need further evaluation in the field (Phase II to re-validate their performance.

    Full Text Available Salmonella is a leading cause of foodborne illness in the United States, with poultry and poultry products being a primary source of infection to humans. Poultry may carry some Salmonella serovars without any signs or symptoms of disease and without causing any adverse effects to the health of the bird. Salmonella may be introduced to a flock by multiple environmental sources, but poultry feed is suspected to be a leading source. Detecting Salmonella in feed can be challenging because low levels of the bacteria may not be recovered using traditional culturing techniques. Numerous detection methodologies have been examined over the years for quantifying Salmonella in feeds and many have proven to be effective for Salmonella isolation and detection in a variety of feeds. However, given the potential need for increased detection sensitivity, molecular detection technologies may the best candidate for developing rapid sensitive methods for identifying small numbers of Salmonella in the background of large volumes of feed. Several studies have been done using polymerase chain reaction (PCR assays and commercial kits to detect Salmonella spp. in a wide variety of feed sources. In addition, DNA array technology has recently been utilized to track the dissemination of a specific Salmonella serotype in feed mills. This review will discuss the processing of feeds and potential points in the process that may introduce Salmonella contamination to the feed. Detection methods currently used and the need for advances in these methods also will be discussed. Finally, implementation of rapid detection for optimizing control methods to prevent and remove any Salmonella contamination of feeds will be considered.

  5. Development and validation of a rapid, aldehyde dehydrogenase bright-based cord blood potency assay. (United States)

    Shoulars, Kevin; Noldner, Pamela; Troy, Jesse D; Cheatham, Lynn; Parrish, Amanda; Page, Kristin; Gentry, Tracy; Balber, Andrew E; Kurtzberg, Joanne


    Banked, unrelated umbilical cord blood provides access to hematopoietic stem cell transplantation for patients lacking matched bone marrow donors, yet 10% to 15% of patients experience graft failure or delayed engraftment. This may be due, at least in part, to inadequate potency of the selected cord blood unit (CBU). CBU potency is typically assessed before cryopreservation, neglecting changes in potency occurring during freezing and thawing. Colony-forming units (CFUs) have been previously shown to predict CBU potency, defined as the ability to engraft in patients by day 42 posttransplant. However, the CFU assay is difficult to standardize and requires 2 weeks to perform. Consequently, we developed a rapid multiparameter flow cytometric CBU potency assay that enumerates cells expressing high levels of the enzyme aldehyde dehydrogenase (ALDH bright [ALDH(br)]), along with viable CD45(+) or CD34(+) cell content. These measurements are made on a segment that was attached to a cryopreserved CBU. We validated the assay with prespecified criteria testing accuracy, specificity, repeatability, intermediate precision, and linearity. We then prospectively examined the correlations among ALDH(br), CD34(+), and CFU content of 3908 segments over a 5-year period. ALDH(br) (r = 0.78; 95% confidence interval [CI], 0.76-0.79), but not CD34(+) (r = 0.25; 95% CI, 0.22-0.28), was strongly correlated with CFU content as well as ALDH(br) content of the CBU. These results suggest that the ALDH(br) segment assay (based on unit characteristics measured before release) is a reliable assessment of potency that allows rapid selection and release of CBUs from the cord blood bank to the transplant center for transplantation. © 2016 by The American Society of Hematology.

  7. Development of materials for the rapid manufacture of die cast tooling (United States)

    Hardro, Peter Jason

    The focus of this research is to develop a material composition that can be processed by rapid prototyping (RP) in order to produce tooling for the die casting process. Where these rapidly produced tools will be superior to traditional tooling production methods by offering one or more of the following advantages: reduced tooling cost, shortened tooling creation time, reduced man-hours for tool creation, increased tool life, and shortened die casting cycle time. By utilizing RP's additive build process and vast material selection, there was a prospect that die cast tooling may be produced quicker and with superior material properties. To this end, the material properties that influence die life and cycle time were determined, and a list of materials that fulfill these "optimal" properties were highlighted. Physical testing was conducted in order to grade the processability of each of the material systems and to optimize the manufacturing process for the downselected material system. Sample specimens were produced and microscopy techniques were utilized to determine a number of physical properties of the material system. Additionally, a benchmark geometry was selected and die casting dies were produced from traditional tool materials (H13 steel) and techniques (machining) and from the newly developed materials and RP techniques (selective laser sintering (SLS) and laser engineered net shaping (LENS)). Once the tools were created, a die cast alloy was selected and a preset number of parts were shot into each tool. During tool creation, the manufacturing time and cost was closely monitored and an economic model was developed to compare traditional tooling to RP tooling. This model allows one to determine, in the early design stages, when it is advantageous to implement RP tooling and when traditional tooling would be best. The results of the physical testing and economic analysis has shown that RP tooling is able to achieve a number of the research objectives, namely

    The inspection information management system for safeguards national inspection is aimed to do the national safeguards inspection with efficiency, and to decrease the inspector's load to write inspection report by systematizing the inspection jobs and sharing the inspection data. National safeguards inspection is consisted two large jobs. The first is the national safeguards supporting job of managing to support the national inspection mission. The other is the writing a national inspection report after completing the national inspection. Before the developing of inspection information management system, the official tools(spread sheet, word processor) are usually used. But there is problem to share the data, to produce the statistics data. To solve the these problem, we developed the inspection information management system that process the job from initial to final inspection work, and opened user education. This paper explain the procedure of developing the inspection information management system for safeguards national inspection.

  10. Developing Visualization Techniques for Semantics-based Information Networks (United States)

    Keller, Richard M.; Hall, David R.


    Information systems incorporating complex network structured information spaces with a semantic underpinning - such as hypermedia networks, semantic networks, topic maps, and concept maps - are being deployed to solve some of NASA s critical information management problems. This paper describes some of the human interaction and navigation problems associated with complex semantic information spaces and describes a set of new visual interface approaches to address these problems. A key strategy is to leverage semantic knowledge represented within these information spaces to construct abstractions and views that will be meaningful to the human user. Human-computer interaction methodologies will guide the development and evaluation of these approaches, which will benefit deployed NASA systems and also apply to information systems based on the emerging Semantic Web.

  11. Environmental risk prioritization and management of petroleum retail facilities using Geographic Information Systems (GIS) and rapid field investigation techniques

    Energy Technology Data Exchange (ETDEWEB)

    Drake, J.T.; Thomas, C.A.; Molloy, K.P. [Camp Dresser & McKee Inc., Cambridge, MA (United States)] [and others


    Environmental risk prioritization is a method of estimating the probability and severity of an environmental impact related to a petroleum facility. The risk analysis is directed at prioritizing environmental risks associated with each facility and so that capital expenditures can be directed toward mitigation at high risk sites and monitoring or stewardship at low risk locations. The expenditures or investments may include facility upgrades, waste disposal or containment, soil and water remediation, or facility monitoring activities. The risk analyses and petroleum retail facilities prioritization system presented in this paper includes a geographic information systems (GIS) and rapid field investigation techniques. This system was recently used in the prioritization of 150 petroleum facilities in Caracas, Venezuela and is currently being expanded to include additional facilities. The prioritization system used GIS and a data management system to quantify the Potential Impact Factors (PIF) and the Leak Likelihood Factors (LLF) associated with each facility. The PIF analysis used GIS to perform a proximity analysis; a radial search was performed for each site identifying proximal receptors including sensitive environmental receptors, water supply well locations, protected open spaces, water supply watersheds, areas of critical environmental concern, and residential populations. The LLF analysis assessed risk based on the age of the underground storage tanks, presence of leak protection devices, soils and groundwater conditions, tank and piping characteristics, sales volume and proximity to sources of high voltage. Prioritization weighting was placed on each of the LLF factors based on the risk associated with each. After the initial GIS site rankings, rapid site audits were completed selected the high risk sites. These audits included compilation of spill histories and soil vapor analyses using gas chromatography.

  12. Information Literacy Policy Development in Canada: Is It Time?

    Directory of Open Access Journals (Sweden)

    Cara Bradley


    Full Text Available This article examines policy issues related to information literacy in Canada. It provides some background on the information literacy concept, reflecting on popular definitions offered by American, British, and Australian library associations, before advocating for a broader definition that views information literacy as a human right. Information literacy is also considered in relationship to the proliferation of other “literacies,” such as digital, web, media, and information technology, that are the subject of increased advocacy and attention from interest groups and educators. The ongoing need for improved information literacy levels is analyzed not only in the context of inputs (the increasing complexity of the information environment but also in terms of potential personal, social, and economic outcomes that can be realized through widespread information literacy education efforts. The paper argues that information literacy must become a priority not only among academic librarians but also school, public, and special librarians, as well as others outside of the library sector, if significant improvements in information literacy levels are to be realized. Such a coordinated approach can only be achieved in the context of policies that require, and adequately support, widespread efforts at improving information literacy levels. After a review of the ad-hoc state of information literacy education in Canada today, this paper analyzes information literacy-related policy development efforts in Canada to date in the four arenas where one would expect to see such activity: the Government of Canada, provincial governments, library associations, and other stakeholder groups. This article aims to start a wide-reaching discussion about information literacy and associated policy issues in Canada.

  13. Development of loop-mediated isothermal amplification for rapid detection of Entamoeba histolytica. (United States)

    Rivera, Windell L; Ong, Vanissa A


    To develop a loop-mediated isothermal amplification (LAMP) assay for the detection of Entamoeba histolytica E. histolytica, the causative agent of amebiasis. The LAMP primer set was designed from E. histolytica hemolysin gene HLY6. Genomic DNA of E. histolytica trophozoites strain HK9 was used to optimize the LAMP mixture and conditions. Amplification of DNA in the LAMP mixture was monitored through visual inspection for turbidity of the LAMP mix as well as addition of fluorescent dye. Positive LAMP reactions turned turbid while negative ones remained clear. Upon addition of a fluorescent dye, all positive reactions turned green while the negative control remained orange under ambient light. After electrophoresis in 1.5% agarose gels, a ladder of multiple bands of different sizes can be observed in positive samples while no bands were detected in the negative control. The sensitivity of the assay was found to be 5 parasites per reaction which corresponds to approximately 15.8 ng/μ L DNA. The specificity of the assay was verified by the absence of amplified products when DNA from other gastrointestinal parasites such as the morphologically similar but non-pathogenic species, Entamoeba dispar 39, and other diarrhea-causing organisms such as Blastocystis hominis and Escherichia coli were used. The LAMP assay we have developed enables the detection of E. histolytica with rapidity and ease, therefore rendering it is suitable for laboratory and field diagnosis of amebiasis.

  14. SCOUT: developing a modular multimission spacecraft architecture for high-capability rapid access to space (United States)

    Rogers, Aaron; Shoemaker, James; Jordan, Luis; McDermott, Scott


    The long lead and cycle times currently associated with development and launch of satellite systems have established a prohibitive environment for responsive deployment of tactical capability to orbit. With the advent of the RASCAL program - poised to offer launch capability to Low Earth Orbit (LEO) within 24 hours - there is a clear motivation for a comparable, multi-mission, rapidly configurable microsatellite. The SCOUT program is developing the key enabling technologies that will enable this capability while also addressing the production and logistic challenges essential to its implementation. Intrinsic to the design will be a "Plug-and-Sense" capability, which will enable a vehicle to detect the presence and orientation of integrated subsystem modules, as well as ascertain their function, and communicate key performance parameters. The system will utilize a heuristic, self-interrogation approach to provide a robust means of performing configuration and diagnostics activities that transcend nominal housekeeping routines to include an enhanced degree of system autonomy. A minimally structured design, emphasizing a lightweight, interchangeable framework will enable quick integration and deployment, while preserving high on-orbit payload mass fraction. Similarly, the system will also feature a novel approach to assembly, integration, and test activities that spans ground through on-orbit operations.

  15. Ideas for the rapid development of the structural models in mechanical engineering (United States)

    Oanta, E.; Raicu, A.; Panait, C.


    Conceiving computer based instruments is a long run concern of the authors. Some of the original solutions are: optimal processing of the large matrices, interfaces between the programming languages, approximation theory using spline functions, numerical programming increased accuracy based on the extended arbitrary precision libraries. For the rapid development of the models we identified the following directions: atomization, ‘librarization’, parameterization, automatization and integration. Each of these directions has some particular aspects if we approach mechanical design problems or software development. Atomization means a thorough top-down decomposition analysis which offers an insight regarding the basic features of the phenomenon. Creation of libraries of reusable mechanical parts and libraries of programs (data types, functions) save time, cost and effort when a new model must be conceived. Parameterization leads to flexible definition of the mechanical parts, the values of the parameters being changed either using a dimensioning program or in accord to other parts belonging to the same assembly. The resulting templates may be also included in libraries. Original software applications are useful for the model’s input data generation, to input the data into CAD/FEA commercial applications and for the data integration of the various types of studies included in the same project.

    To generate monoclonal antibodies (MAbs) for developing a rapid malaria diagnostic urine-based assay (RUBDA), using Plasmodium-infected human urinary antigens. Plasmodium-infected human urinary (PAgHU) and cultured parasite (CPfAg) antigens were used to generate mouse MAbs. The reactivity and accuracy of the MAbs produced were then evaluated using microplate ELISA, SDS-PAGE, Western blotting assay, microscopy and immunochromatographic tests. Ninety-six MAb clones were generated, of which 68.8% reacted to both PAgHU and CPfAg, 31.3% reacted to PAgHU only, and none reacted to CPfAg only. One promising MAb (UCP4W7) reacted in WBA, to both PAgHU and CPfAg, but not to Plasmodium-negative human urine and blood, Schistosoma haematobium and S. mansoni antigens nor measles and poliomyelitis vaccines. MAb UCP4W7 seems promising for diagnosing Plasmodium infection. Urine is a reliable biomarker source for developing non-invasive malaria diagnostic tests. SDS-PAGE and MAb-based WBA appear explorable in assays for detecting different levels of Plasmodium parasitaemia. © 2016 John Wiley & Sons Ltd.

    Full Text Available In mitigating urban transportation problems and providing a sustainable transit system, rail-based systems have become popular. While rail-based systems are welcome in many developed countries, it is impractical for cities in developing countries due to the high cost of system building and operation. Thus, a staged or incremental adjustment towards fixed guide way transit implementation of greater interest to many agencies today, and these days it has started developing in terms of Bus Rapid Transit (BRT. As it is very new to developing cities, it is a challenge to get the users to understand the system and to grasp their attitude. Besides, there are many other general issues like literacy, lack of a sample frame etc. Survey design needs to be tuned carefully for these cities to obtain a resonant output. Concerning all these problems, a hypothetical questionnaire survey such as Stated Preference (SP has become popular. This study conducted a survey on BRT implementation with SP as a hypothetical tool at a selected corridor in Colombo, the capital of Sri Lanka. The main objectives were to identify questionnaire design(media effects, literacy of users, segmental variation, and the important variable(s. In this survey design, system explanation has been set in two slightly different ways (media: TEXT ∼ IMAGE for comparison and it was found that even a slight difference on design affected the users' response considerably. Income level could not be predicted directly, but car ownership was found to be a good predictor, it was found to be an important variable and it showed a correlation with literacy.

  18. Developing an Institutional Repository of Digital Health Information Content. (United States)

    Kolokathi, Aikaterini; Mantas, John


    Over the past few years, the use of electronic sources for studies by students and teaching staff has been rapidly increased. The digital information gives the opportunity of personal and interactive information. Nevertheless, much of health information is unable to be identified from existing search tools. The aim of this paper is to propose a system which enables academic members of the Faculty of Nursing of the University of Athens to immediate access information that improves patient care and the daily nursing practice. First of all, in order to achieve this goal, an on-line research was conducted on Science Direct, Scopus, PubMed and Google Scholar. Afterwards, the appropriate digital library software package was selected. This work presents the institutional repository "Ariadne". This repository is a new service which intends to establish new conditions to archiving of graduate and doctoral dissertations. The "Ariadne" repository is not just a tool for strengthening the educational process but also a tool for further progress of nursing science.

  19. Development of a GIS-based spill management information system. (United States)

    Martin, Paul H; LeBoeuf, Eugene J; Daniel, Edsel B; Dobbins, James P; Abkowitz, Mark D


    Spill Management Information System (SMIS) is a geographic information system (GIS)-based decision support system designed to effectively manage the risks associated with accidental or intentional releases of a hazardous material into an inland waterway. SMIS provides critical planning and impact information to emergency responders in anticipation of, or following such an incident. SMIS couples GIS and database management systems (DBMS) with the 2-D surface water model CE-QUAL-W2 Version 3.1 and the air contaminant model Computer-Aided Management of Emergency Operations (CAMEO) while retaining full GIS risk analysis and interpretive capabilities. Live 'real-time' data links are established within the spill management software to utilize current meteorological information and flowrates within the waterway. Capabilities include rapid modification of modeling conditions to allow for immediate scenario analysis and evaluation of 'what-if' scenarios. The functionality of the model is illustrated through a case study of the Cheatham Reach of the Cumberland River near Nashville, TN.

  20. Identification at the crime scene: The sooner, the better? The interpretation of rapid identification information by CSIs at the crime scene. (United States)

    de Gruijter, Madeleine; Nee, Claire; de Poot, Christianne J


    New technologies will allow Crime Scene Investigators (CSIs) in the near future to analyse traces at the crime scene and receive identification information while still conducting the investigation. These developments could have considerable effects on the way an investigation is conducted. CSIs may start reasoning based on possible database-matches which could influence scenario formation (i.e. the construction of narratives that explain the observed traces) during very early phases of the investigation. The goal of this study is to gain more insight into the influence of the rapid identification information on the reconstruction of the crime and the evaluation of traces by addressing two questions, namely 1) is scenario formation influenced from the moment that ID information is provided and 2) do database matches influence the evaluation of traces and the reconstruction of the crime. We asked 48 CSIs from England to investigate a potential murder crime scene on a computer. Our findings show that the interpretation of the crime scene by CSIs is affected by the moment identification information is provided. This information has a higher influence on scenario formation when provided after an initial scenario has been formed. Also, CSIs seem to attach great value to traces that produce matches with databases and hence yield a name of a known person. Similar traces that did not provide matches were considered less important. We question whether this kind of selective attention is desirable as it may cause ignorance of other relevant information at the crime scene.

  10. Information and Communication Technology: Gender Issues in Developing Nations

    Directory of Open Access Journals (Sweden)

    Kimberly Betz Leahy


    Full Text Available As Developing Nations seek to leverage scarce resources toward the goal of achieving a developed status they must reevaluate past practices and explore available and affordable technologies. Where in-formation and communication infrastructures are weak, use of low-cost, easily distributed technologies have proven effective. Still, many developing nations have failed to incorporate a resource in great abundance, their women, to use these new technologies to greatest advantage. This paper will address the implications of women's lack of economic and educational parity, and offer examples of how the education of women through the use of information and communication technology can enhance a nation's gross domestic product (GDP.

  13. Development of a rapid matrix digestion technique for ultrastructural analysis of elastic fibers in the intervertebral disc. (United States)

    Tavakoli, Javad; Costi, John J


    Collagen and elastic fibers are two major fibrous constituents of the annulus fibrosus (AF) in the disc that contribute to its mechanical and viscoelastic properties. It was thought that elastic fibers play no substantial role in the function and properties of the disc as these fibers were irregularly distributed. Studies that have revealed highly organized elastic fibers with different regional orientation and distribution, while being strongly crosslinked with matrix, suggesting their contribution to disc structure-function properties. These studies that were performed by light microscopic analysis of histologically prepared samples, have not been able to reveal the fine-scale architectural details of the elastic fiber network. Since elastic fibers are intermingled with other fibrous components of the disc and mostly obscured by the extracellular matrix, it is difficult to demonstrate their ultra-structural organization using scanning electron microscopy (SEM). Therefore the aim of this study was to develop a rapid matrix digestion technique for ultrastructural analysis of the disc elastic fibers. This study provides a new method for fundamental visualization of elastic fibers and their architecture in the disc. Through the ultra-structural analysis, the relationship between structure and function, as well as the role of elastic fibers on AF mechanical properties can be studied. This method may be used to develop a three-dimensional map of elastic fibers distribution within the disc, which would provide valuable information for designing tissue engineered scaffolds for AF repair and replacement.

  14. Development of a fluorescence in situ hybridization (FISH) method for rapid detection of Ulva prolifera (United States)

    Zhang, Qing-Chun; Liu, Qing; Kang, Zhen-Jun; Yu, Ren-Cheng; Yan, Tian; Zhou, Ming-Jiang


    Large-scale green tides have occurred consecutively since 2007 in the Yellow Sea (YS), China. The dominant causative species of the green tides has been identified as Ulva prolifera. The origin of green tides in the YS has been traced back to the Subei Shoal based on the results of remote-sensing, numerical simulations and field investigations. However, it is difficult to study the early development of green tides in the Subei Shoal because of the mixture of multiple green algae and the morphological diversity of U. prolifera when under variable environmental conditions. In this study, a rapid and accurate fluorescence in situ hybridization (FISH) method was developed to detect U. prolifera from the community of green algae targeting the 5S rDNA spacer region of U. prolifera. Two specific probes, 5S-1 and 5S-2, were designed based on the sequences of the 5S rDNA spacer regions of U. prolifera, Ulva linza and Ulva flexuosa. Specificity of the FISH method was tested using the six species of green algae commonly occurring in the Subei Shoal, including U. prolifera, U. linza, U. flexuosa, Ulva compressa, Ulva pertusa and Blidingia sp. The results showed that only U. prolifera could be labeled with both probes. Probe 5S-1, which showed a much higher labeling efficiency on U. prolifera, was ultimately selected as the probe for the FISH detection. The sample preparation method was optimized, particularly for the mature green algae, by the addition of cellulase and proteinase K in the pre-hybridization solution. Labeling efficiency with the probe 5S-1 reached 96% on average under the optimized conditions. The successful development of the FISH method has been applied to qualitative and quantitative analysis of field samples collected from the YS, and the results indicate a potential use in future green algae studies.

  15. Development of a prototype lateral flow immunoassay (LFI for the rapid diagnosis of melioidosis.

    Directory of Open Access Journals (Sweden)

    Raymond L Houghton


    Full Text Available Burkholderia pseudomallei is a soil-dwelling bacterium and the causative agent of melioidosis. Isolation of B. pseudomallei from clinical samples is the "gold standard" for the diagnosis of melioidosis; results can take 3-7 days to produce. Alternatively, antibody-based tests have low specificity due to a high percentage of seropositive individuals in endemic areas. There is a clear need to develop a rapid point-of-care antigen detection assay for the diagnosis of melioidosis. Previously, we employed In vivo Microbial Antigen Discovery (InMAD to identify potential B. pseudomallei diagnostic biomarkers. The B. pseudomallei capsular polysaccharide (CPS and numerous protein antigens were identified as potential candidates. Here, we describe the development of a diagnostic immunoassay based on the detection of CPS. Following production of a CPS-specific monoclonal antibody (mAb, an antigen-capture immunoassay was developed to determine the concentration of CPS within a panel of melioidosis patient serum and urine samples. The same mAb was used to produce a prototype Active Melioidosis Detect Lateral Flow Immunoassay (AMD LFI; the limit of detection of the LFI for CPS is comparable to the antigen-capture immunoassay (∼0.2 ng/ml. The analytical reactivity (inclusivity of the AMD LFI was 98.7% (76/77 when tested against a large panel of B. pseudomallei isolates. Analytical specificity (cross-reactivity testing determined that 97.2% of B. pseudomallei near neighbor species (35/36 were not reactive. The non-reactive B. pseudomallei strain and the reactive near neighbor strain can be explained through genetic sequence analysis. Importantly, we show the AMD LFI is capable of detecting CPS in a variety of patient samples. The LFI is currently being evaluated in Thailand and Australia; the focus is to optimize and validate testing procedures on melioidosis patient samples prior to initiation of a large, multisite pre-clinical evaluation.

  16. VaxCelerate II: rapid development of a self-assembling vaccine for Lassa fever. (United States)

    Leblanc, Pierre; Moise, Leonard; Luza, Cybelle; Chantaralawan, Kanawat; Lezeau, Lynchy; Yuan, Jianping; Field, Mary; Richer, Daniel; Boyle, Christine; Martin, William D; Fishman, Jordan B; Berg, Eric A; Baker, David; Zeigler, Brandon; Mais, Dale E; Taylor, William; Coleman, Russell; Warren, H Shaw; Gelfand, Jeffrey A; De Groot, Anne S; Brauns, Timothy; Poznansky, Mark C


    Development of effective vaccines against emerging infectious diseases (EID) can take as much or more than a decade to progress from pathogen isolation/identification to clinical approval. As a result, conventional approaches fail to produce field-ready vaccines before the EID has spread extensively. Lassa is a prototypical emerging infectious disease endemic to West Africa for which no successful vaccine is available. We established the VaxCelerate Consortium to address the need for more rapid vaccine development by creating a platform capable of generating and pre-clinically testing a new vaccine against specific pathogen targets in less than 120 d A self-assembling vaccine is at the core of the approach. It consists of a fusion protein composed of the immunostimulatory Mycobacterium tuberculosis heat shock protein 70 (MtbHSP70) and the biotin binding protein, avidin. Mixing the resulting protein (MAV) with biotinylated pathogen-specific immunogenic peptides yields a self-assembled vaccine (SAV). To meet the time constraint imposed on this project, we used a distributed R&D model involving experts in the fields of protein engineering and production, bioinformatics, peptide synthesis/design and GMP/GLP manufacturing and testing standards. SAV immunogenicity was first tested using H1N1 influenza specific peptides and the entire VaxCelerate process was then tested in a mock live-fire exercise targeting Lassa fever virus. We demonstrated that the Lassa fever vaccine induced significantly increased class II peptide specific interferon-γ CD4(+) T cell responses in HLA-DR3 transgenic mice compared to peptide or MAV alone controls. We thereby demonstrated that our SAV in combination with a distributed development model may facilitate accelerated regulatory review by using an identical design for each vaccine and by applying safety and efficacy assessment tools that are more relevant to human vaccine responses than current animal models.

  17. Application of a novel automatic disintegration apparatus for the development and evaluation of a direct compression rapidly disintegrating tablet. (United States)

    Jung, Huijeong Ashley; Augsburger, Larry L


    An automatic disintegration tester was developed and used to explore disintegration mechanism and times of rapidly disintegrating tablets. DT50, the time required for a tablet to decrease in its thickness by half, allowed an unbiased determination of disintegration time. Calcium silicate concentration, Explotab® concentration, DiPac®/Xylitab® ratio as fillers, and compression pressure were evaluated using a central composite model design analysis for their DT50, tensile strength, and friability. Tablets that could reasonably be handled (friability tablets, originally measured by Caramella et al. using force kinetics, could be determined from axial displacement data measured directly without the need to assume that disintegration force generation was indicative of changes in tablet volume. The n values of tablets containing calcium silicate, Ditab® and/or Xylitab®, magnesium stearate, and Explotab® suggested that the amount of Explotab® was not a significant factor in determining the disintegration mechanism; however, the type of disintegrant used did alter the n value. Primojel® and Explotab®, which are in the same class of disintegrants, exhibited similar DT50, n, and k. Polyplasdone® XL exhibited a much higher n, while yielding faster DT50, suggesting that its performance is more dependent on facilitating the interfacial separation of particles. AcDiSol® showed no apparent moisture sensitivity in regards to disintegration efficiency. The use of the novel apparatus proved to be useful in measuring disintegration efficiency of rapidly disintegrating tablets and in providing valuable information on the disintegration phenomena.

  18. Improving the extraction of crisis information in the context of flood, fire, and landslide rapid mapping using SAR and optical remote sensing data (United States)

    Martinis, Sandro; Clandillon, Stephen; Twele, André; Huber, Claire; Plank, Simon; Maxant, Jérôme; Cao, Wenxi; Caspard, Mathilde; May, Stéphane


    Optical and radar satellite remote sensing have proven to provide essential crisis information in case of natural disasters, humanitarian relief activities and civil security issues in a growing number of cases through mechanisms such as the Copernicus Emergency Management Service (EMS) of the European Commission or the International Charter 'Space and Major Disasters'. The aforementioned programs and initiatives make use of satellite-based rapid mapping services aimed at delivering reliable and accurate crisis information after natural hazards. Although these services are increasingly operational, they need to be continuously updated and improved through research and development (R&D) activities. The principal objective of ASAPTERRA (Advancing SAR and Optical Methods for Rapid Mapping), the ESA-funded R&D project being described here, is to improve, automate and, hence, speed-up geo-information extraction procedures in the context of natural hazards response. This is performed through the development, implementation, testing and validation of novel image processing methods using optical and Synthetic Aperture Radar (SAR) data. The methods are mainly developed based on data of the German radar satellites TerraSAR-X and TanDEM-X, the French satellite missions Pléiades-1A/1B as well as the ESA missions Sentinel-1/2 with the aim to better characterize the potential and limitations of these sensors and their synergy. The resulting algorithms and techniques are evaluated in real case applications during rapid mapping activities. The project is focussed on three types of natural hazards: floods, landslides and fires. Within this presentation an overview of the main methodological developments in each topic is given and demonstrated in selected test areas. The following developments are presented in the context of flood mapping: a fully automated Sentinel-1 based processing chain for detecting open flood surfaces, a method for the improved detection of flooded vegetation

It is therefore important to acquire the spatial data and carefully design the data base for it. Variety and the complexity of the spatial data, however, necessitate to develop a systematic approach to acquire, store, manage, query and analyze the spatial information. Here, we developed a preliminary database design including capturing and organizing spatial data as well as creating database schema and data dictionary towards the establishment of orest information system using GIS. We tested the data base in a small forest management unit.

  20. A tool for rapid assessment of product usability and universal design: development and preliminary psychometric testing. (United States)

    Lenker, James A; Nasarwanji, Mahiyar; Paquet, Victor; Feathers, David


    While there are many available tools and methods to evaluate product usability, few have been tested on user groups with disabilities and even fewer systematically consider universal design principles. This paper describes the development and preliminary psychometric testing of the Rapid Assessment of Product Usability & Universal Design (RAPUUD), a 12-item user-report tool based on the seven principles of universal design. A preliminary set of items was created to elicit ratings of diverse product characteristics (e.g., physical effort, cognitive effort, assistance required, safety). Data were gathered from 61 participants who rated the usability of products they use in their own environments. Each item elicited a full range of responses, with no apparent floor or ceiling effects. Collectively, the 12 items achieved a high internal consistency (Cronbach's α=0.80). The data indicate that the tool was sensitive to differences in functional abilities, as well as differences in product characteristics. The instrument was usable for a range of consumer products, though not all items were appropriate for each and every product. The results suggest that the instrument could become a pragmatic tool for designers to identify usability problems experienced by a diversity of user populations. © 2011 - IOS Press and the authors.

  1. Payments for carbon sequestration to alleviate development pressure in a rapidly urbanizing region (United States)

    Smith, Jordan W.; Dorning, Monica; Shoemaker, Douglas A.; Méley, Andréanne; Dupey, Lauren; Meentemeyer, Ross K.


    The purpose of this study was to determine individuals' willingness to enroll in voluntary payments for carbon sequestration programs through the use of a discrete choice experiment delivered to forest owners living in the rapidly urbanizing region surrounding Charlotte, North Carolina. We examined forest owners' willingness to enroll in payments for carbon sequestration policies under different levels of financial incentives (annual revenue), different contract lengths, and different program administrators (e.g., private companies versus a state or federal agency). We also examined the influence forest owners' sense of place had on their willingness to enroll in hypothetical programs. Our results showed a high level of ambivalence toward participating in payments for carbon sequestration programs. However, both financial incentives and contract lengths significantly influenced forest owners' intent to enroll. Neither program administration nor forest owners' sense of place influenced intent to enroll. Although our analyses indicated that payments from carbon sequestration programs are not currently competitive with the monetary returns expected from timber harvest or property sales, certain forest owners might see payments for carbon sequestration programs as a viable option for offsetting increasing tax costs as development encroaches and property values rise.

  2. The multimod application framework: a rapid application development tool for computer aided medicine. (United States)

    Viceconti, Marco; Zannoni, Cinzia; Testi, Debora; Petrone, Marco; Perticoni, Stefano; Quadrani, Paolo; Taddei, Fulvia; Imboden, Silvano; Clapworthy, Gordon


    This paper describes a new application framework (OpenMAF) for rapid development of multimodal applications in computer-aided medicine. MAF applications are multimodal in data, in representation, and in interaction. The framework supports almost any type of biomedical data, including DICOM datasets, motion-capture recordings, or data from computer simulations (e.g. finite element modeling). The interactive visualization approach (multimodal display) helps the user interpret complex datasets, providing multiple representations of the same data. In addition, the framework allows multimodal interaction by supporting the simultaneous use of different input-output devices like 3D trackers, stereoscopic displays, haptics hardware and speech recognition/synthesis systems. The Framework has been designed to run smoothly even on limited power computers, but it can take advantage of all hardware capabilities. The Framework is based on a collection of portable libraries and it can be compiled on any platform that supports OpenGL, including Windows, MacOS X and any flavor of Unix/linux.

    Briana Spolding

    Full Text Available BACKGROUND AND AIMS: A major impediment to establishing new treatments for non-alcoholic steatohepatitis is the lack of suitable animal models that accurately mimic the biochemical and metabolic characteristics of the disease. The aim of this study was to explore a unique polygenic animal model of metabolic disease as a model of non-alcoholic steatohepatitis by determining the effects of 2% dietary cholesterol supplementation on metabolic and liver endpoints in Psammomys obesus (Israeli sand rat. METHODS: P. obesus were provided ad libitum access to either a standard rodent diet (20% kcal/fat or a standard rodent diet supplemented with 2% cholesterol (w/w for 4 weeks. Histological sections of liver from animals on both diets were examined for key features of non-alcoholic steatohepatitis. The expression levels of key genes involved in hepatic lipid metabolism were measured by real-time PCR. RESULTS: P. obesus fed a cholesterol-supplemented diet exhibited profound hepatomegaly and steatosis, and higher plasma transaminase levels. Histological analysis identified extensive steatosis, inflammation, hepatocyte injury and fibrosis. Hepatic gene expression profiling revealed decreased expression of genes involved in delivery and uptake of lipids, and fatty acid and triglyceride synthesis, and increased expression of genes involved in very low density lipoprotein cholesterol synthesis, triglyceride and cholesterol export. CONCLUSIONS: P. obesus rapidly develop non-alcoholic steatohepatitis when fed a cholesterol-supplemented diet that appears to be histologically and mechanistically similar to patients.

  4. Development of Isothermal Recombinase Polymerase Amplification Assay for Rapid Detection of Porcine Circovirus Type 2

    Yang Yang


    Full Text Available Porcine circovirus virus type II (PCV2 is the etiology of postweaning multisystemic wasting syndrome (PMWS, porcine dermatitis, nephropathy syndrome (PDNS, and necrotizing pneumonia. Rapid diagnosis tool for detection of PCV2 plays an important role in the disease control and eradication program. Recombinase polymerase amplification (RPA assays using a real-time fluorescent detection (PCV2 real-time RPA assay and RPA combined with lateral flow dipstick (PCV2 RPA LFD assay were developed targeting the PCV2 ORF2 gene. The results showed that the sensitivity of the PCV2 real-time RPA assay was 102 copies per reaction within 20 min at 37°C and the PCV2 RPA LFD assay had a detection limit of 102 copies per reaction in less than 20 min at 37°C. Both assays were highly specific for PCV2, with no cross-reactions with porcine circovirus virus type 1, foot-and-mouth disease virus, pseudorabies virus, porcine parvovirus, porcine reproductive and respiratory syndrome virus, and classical swine fever virus. Therefore, the RPA assays provide a novel alternative for simple, sensitive, and specific identification of PCV2.

  5. Rapid development of pulmonary cavitation as manifestation of a candida species

    Energy Technology Data Exchange (ETDEWEB)

    Rix, E.; Bickel, R.H.; Baldauf, G.


    The roentgenologic pattern of the pulmonary manifestation of candida species, resulting in a rapid development of pulmonary cavitations with mycetoma-like structures, was described in three patients. All patients, undergoing antineoplastic chemotherapy because of acute leukemia, presented with fever and expectoration, which were resistant to various antibiotic regimes. Cultures of blood and urine were sterile; but Torulopsis glabrata, a candida species, was found in multiple cultures of the sputum of all patients and also in a bronchoscopic lavage obtained from one patient after reconstitution of the granulopoesis. The roetgenologic appearance of the infiltrates was accompanied by a rise of the Ig-M immunoglobulins against candida. Following intravenous treatment with amphotericin B a reduction of the cavitation and of the infiltrates to small residues was observed. Simultaneously the body temperature and the sputum became normal and a fall in the immunoglobulin titers was found. The diagnostic problems of pulmonary cavitation and especially of pulmonary mycosis in immuosuppressed and therapy-induced granulocytopenic and thrombocytopenic patients with acute leukemia were discussed.

  6. Rapid recognition at 10 months as a predictor of language development. (United States)

    Junge, Caroline; Kooijman, Valesca; Hagoort, Peter; Cutler, Anne


    Infants' ability to recognize words in continuous speech is vital for building a vocabulary. We here examined the amount and type of exposure needed for 10-month-olds to recognize words. Infants first heard a word, either embedded within an utterance or in isolation, then recognition was assessed by comparing event-related potentials to this word versus a word that they had not heard directly before. Although all 10-month-olds showed recognition responses to words first heard in isolation, not all infants showed such responses to words they had first heard within an utterance. Those that did succeed in the latter, harder, task, however, understood more words and utterances when re-tested at 12 months, and understood more words and produced more words at 24 months, compared with those who had shown no such recognition response at 10 months. The ability to rapidly recognize the words in continuous utterances is clearly linked to future language development. © 2012 Blackwell Publishing Ltd.

  8. Development and validation of a rapid test system for detection of pork meat and collagen residues. (United States)

    Masiri, J; Benoit, L; Barrios-Lopez, B; Thienes, C; Meshgi, M; Agapov, A; Dobritsa, A; Nadala, C; Samadpour, M


    Mislabeling, contamination, and economic adulteration of meat products with undeclared pork tissues are illegal under regulations promulgated by numerous regulatory agencies. Nonetheless, analysis of the European meat industry has revealed pervasive meat adulteration, necessitating more extensive application of meat authentication testing. As existing methods for meat speciation require specialized equipment and/or training, we developed a detection system based on a lateral flow device (LFD) assay format capable of rapidly (~35min) identifying porcine residues derived from raw meat, cooked meat, and gelatin down to 0.01%, 1.0%, and 2.5% contamination, respectively. Specificity analysis revealed no cross-reactivity with meat derived from chicken, turkey, horse, beef, lamb, or goat. Comparison with a commercial ELISA kit and PCR method revealed similar if not improved sensitivity, with the added feature that the LFD-based system required considerably less time to perform. Accordingly, this test system should aid the food industry and food control authorities in monitoring for adulteration with pork. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Aim Candida spp. infection commonly occur in immunocompromised patients. Biochemical assay for identification of Candida spp. is time-consuming and shows many undetermined results. Specific detection for antibody, antigen and metabolites of Candida spp. had low sensitivity and specificity. In this study, we developed a rapid diagnostic method, Multiplex-PCR, to identify Candida spp.Methods Five Candida spp. isolates were cultured, identifi ed with germ tube and API® 20 C AUX (BioMerieux® SA kit. Furthermore, DNA was purified by QIAamp DNA mini (Qiagen® kit for Multiplex-PCR assay.Results DNA detection limit by Multiplex-PCR assays for C. albicans, C. tropicalis, C. parapsilosis, C. krusei and C. glabrata were 4 pg, 0.98 pg, 0.98 pg, 0.5 pg and 16 pg respectively. This assay was also more sensitive than culture in that Multiplex-PCR could detect 2.6-2.9 x 100 CFU/ml, whereas culture 2.6-2.9 x 102 CFU/ml.Conclusion Multiplex-PCR is much more sensitive than culture and thus, can be recommended as a sensitive and specific assay for identification of Candida spp. (Med J Indones 2010; 19:83-7Keywords: Candida spp., multiplex-PCR

  10. Development of a micropulverized extraction method for rapid toxicological analysis of methamphetamine in hair. (United States)

    Miyaguchi, Hajime; Kakuta, Masaya; Iwata, Yuko T; Matsuda, Hideaki; Tazawa, Hidekatsu; Kimura, Hiroko; Inoue, Hiroyuki


    We developed a rapid sample preparation method for the toxicological analysis of methamphetamine and amphetamine (the major metabolite of methamphetamine) in human hair by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), to facilitate fast screening and quantitation. Two milligrams of hair were mechanically micropulverized for 5 min in a 2-ml plastic tube together with 100 microl of an aqueous solvent containing 10% acetonitrile, 100 mM trifluoroacetic acid and the corresponding deuterium analogues as internal standards. The pulverizing highly disintegrated the hair components, simultaneously allowing the extraction of any drugs present in the hair. After filtering the suspension with a membrane-filter unit, the clear filtrate was directly analyzed by HPLC-MS/MS. No evaporation processes were required for sample preparation. Method optimization and validation study were carried out using real-case specimens and fortified samples in which the drugs had been artificially absorbed, respectively. Concentration ranges for quantitation were 0.040-125 and 0.040-25 ng/mg for methamphetamine and amphetamine, respectively. Real-case specimens were analyzed by the method presented here and by conventional ones to verify the applicability of our method to real-world analysis. Our method took less than 30 min for a set of chromatograms to be obtained from a washed hair sample.

  11. Matching time and spatial scales of rapid solidification: dynamic TEM experiments coupled to CALPHAD-informed phase-field simulations (United States)

    Perron, Aurelien; Roehling, John D.; Turchi, Patrice E. A.; Fattebert, Jean-Luc; McKeown, Joseph T.


    A combination of dynamic transmission electron microscopy (DTEM) experiments and CALPHAD-informed phase-field simulations was used to study rapid solidification in Cu–Ni thin-film alloys. Experiments—conducted in the DTEM—consisted of in situ laser melting and determination of the solidification kinetics by monitoring the solid–liquid interface and the overall microstructure evolution (time-resolved measurements) during the solidification process. Modelling of the Cu–Ni alloy microstructure evolution was based on a phase-field model that included realistic Gibbs energies and diffusion coefficients from the CALPHAD framework (thermodynamic and mobility databases). DTEM and post mortem experiments highlighted the formation of microsegregation-free columnar grains with interface velocities varying from ∼0.1 to ∼0.6 m s‑1. After an ‘incubation’ time, the velocity of the planar solid–liquid interface accelerated until solidification was complete. In addition, a decrease of the temperature gradient induced a decrease in the interface velocity. The modelling strategy permitted the simulation (in 1D and 2D) of the solidification process from the initially diffusion-controlled to the nearly partitionless regimes. Finally, results of DTEM experiments and phase-field simulations (grain morphology, solute distribution, and solid–liquid interface velocity) were consistent at similar time (μs) and spatial scales (μm).

  13. Development of rapid methods for relaxation time mapping and motion estimation using magnetic resonance imaging

    Energy Technology Data Exchange (ETDEWEB)

    Gilani, Syed Irtiza Ali


    Recent technological developments in the field of magnetic resonance imaging have resulted in advanced techniques that can reduce the total time to acquire images. For applications such as relaxation time mapping, which enables improved visualisation of in vivo structures, rapid imaging techniques are highly desirable. TAPIR is a Look- Locker-based sequence for high-resolution, multislice T{sub 1} relaxation time mapping. Despite the high accuracy and precision of TAPIR, an improvement in the k-space sampling trajectory is desired to acquire data in clinically acceptable times. In this thesis, a new trajectory, termed line-sharing, is introduced for TAPIR that can potentially reduce the acquisition time by 40 %. Additionally, the line-sharing method was compared with the GRAPPA parallel imaging method. These methods were employed to reconstruct time-point images from the data acquired on a 4T high-field MR research scanner. Multislice, multipoint in vivo results obtained using these methods are presented. Despite improvement in acquisition speed, through line-sharing, for example, motion remains a problem and artefact-free data cannot always be obtained. Therefore, in this thesis, a rapid technique is introduced to estimate in-plane motion. The presented technique is based on calculating the in-plane motion parameters, i.e., translation and rotation, by registering the low-resolution MR images. The rotation estimation method is based on the pseudo-polar FFT, where the Fourier domain is composed of frequencies that reside in an oversampled set of non-angularly, equispaced points. The essence of the method is that unlike other Fourier-based registration schemes, the employed approach does not require any interpolation to calculate the pseudo-polar FFT grid coordinates. Translation parameters are estimated by the phase correlation method. However, instead of two-dimensional analysis of the phase correlation matrix, a low complexity subspace identification of the phase

  14. Development of an isothermal amplification-based assay for the rapid visual detection of Salmonella bacteria. (United States)

    Liu, Hai-Bin; Zang, Yu-Xuan; Du, Xin-Jun; Li, Ping; Wang, Shuo


    The efficient and timely detection of pathogens is a major concern worldwide. The aim of this study was to establish a rapid detection method for Salmonella bacteria in food samples to facilitate timely treatment. Widely used detection methods currently include culture-based methods and PCR-based methods. The former are time consuming, requiring 2 to 3 d, whereas the latter have higher accuracy but are typically complicated, requiring expertise and expensive instruments. In this study, a sensitive and rapid approach for the visual and point-of-use detection of Salmonella bacteria based on recombinase polymerase amplification (RPA) and a lateral-flow (LF) nucleic acid strip was established. We designed a pair of primers according to the invA gene of Salmonella bacteria: one was modified with digoxin, and the other was modified with biotin. In the presence of the biotin- and digoxin-modified primers and target DNA, the RPA produced a substantial amount of duplex DNA attached to biotin and digoxin. The products were detected using LF strips through immunoreaction: anti-digoxin antibodies on the gold nanoparticles, digoxin on the duplex, streptavidin on the LF test line, and biotin on the duplex. The developed RPA-LF assay allowed detection of Salmonella genomic DNA in less than 20 min with simple water bath equipment or portable thermal equipment. In addition, the RPA-LF assay was highly sensitive, with a detection limit as low as 20 fg of target DNA or 1.05 × 101 cfu of bacteria in pure culture, and highly specific, exhibiting no cross-reaction with Staphylococcus aureus, Escherichia coli, Listeria monocytogenes, Shigella, Enterobacter aerogenes, or Campylobacter jejuni. Importantly, Salmonella could be detected in milk and chicken breast at concentrations as low as 1.05 × 100 cfu/mL or 1.05 × 100 cfu/g after enrichment for 2 h and in eggs at 1.05 × 100 cfu/g after enrichment for 4 h. Furthermore, RPA was more sensitive than PCR, which requires a thermal cycling

  15. Development of an EMF Measurements Database, EMF Rapid Program, Project #5, Interim Report: April 1995-December 1996

    Energy Technology Data Exchange (ETDEWEB)

    T. Dan Bracken, Inc.


    The EMF measurement data sets in existence today were compiled with varying goals and techniques. Consequently, they have different information content as well as varying logical and physical structure. Future studies will continue to pursue varying goals and utilize techniques that cannot be known in advance. Primary goals for the EMF Measurements Database developed under the Department of Energy EMF RAPID Program are to develop a database structure that can accommodate the diversity of EMF data sets, provide guidance for production of future EMF data sets, and serve as an accessible repository of EMF measurement data. Specific objectives of the EMF Measurements Database are: o to preserve study descriptions, results and data; o to provide readily accessible, well-documented data; and o to facilitate communication among researchers. In addition, the EMF Measurements Database will encourage additional analysis of existing data sets, facilitate analysis of data from multiple projects, support design of new studies, and permit future issues in EMF exposure assessment to be addressed with existing data. Preservation of study descriptions and data is accomplished with a formal, but open, structure. Specifications have been developed for the various elements of the database. Each data set in the database is formally described by a metadata file. The structured metadata file describes the origin, development, logical and physical structure and distribution mechanism for each data set. The metadata for each data set is generated according to a specification developed for the EMF Measurements Database. The actual measurement data is contained in data Products for each data set. The number and type of data product will vary by data set. Most of the data products in the possession of the EMF Measurements Database are available for download from an Internet site. For some data sets, the data products will be maintained by other parties who may have their own access procedures

  16. Software Toolbox Development for Rapid Earthquake Source Optimisation Combining InSAR Data and Seismic Waveforms (United States)

    Isken, Marius P.; Sudhaus, Henriette; Heimann, Sebastian; Steinberg, Andreas; Bathke, Hannes M.


    We present a modular open-source software framework (pyrocko, kite, grond; for rapid InSAR data post-processing and modelling of tectonic and volcanic displacement fields derived from satellite data. Our aim is to ease and streamline the joint optimisation of earthquake observations from InSAR and GPS data together with seismological waveforms for an improved estimation of the ruptures' parameters. Through this approach we can provide finite models of earthquake ruptures and therefore contribute to a timely and better understanding of earthquake kinematics. The new kite module enables a fast processing of unwrapped InSAR scenes for source modelling: the spatial sub-sampling and data error/noise estimation for the interferogram is evaluated automatically and interactively. The rupture's near-field surface displacement data are then combined with seismic far-field waveforms and jointly modelled using the framwork, which allows for fast forward modelling based on pre-calculated elastodynamic and elastostatic Green's functions. Lastly the grond module supplies a bootstrap-based probabilistic (Monte Carlo) joint optimisation to estimate the parameters and uncertainties of a finite-source earthquake rupture model. We describe the developed and applied methods as an effort to establish a semi-automatic processing and modelling chain. The framework is applied to Sentinel-1 data from the 2016 Central Italy earthquake sequence, where we present the earthquake mechanism and rupture model from which we derive regions of increased coulomb stress. The open source software framework is developed at GFZ Potsdam and at the University of Kiel, Germany, it is written in Python and C programming languages. The toolbox architecture is modular and independent, and can be utilized flexibly for a variety of geophysical problems. This work is conducted within the BridGeS project ( funded by the German Research Foundation DFG

  17. Colon cancer in rapidly developing countries: review of the lifestyle, dietary, consanguinity and hereditary risk factors

    Directory of Open Access Journals (Sweden)

    Abdulbari Bener


    Full Text Available Colon cancer rates are rising dramatically in once low incidence nations. These nations are undergoing rapid economic development and are known as “nations in transition” (NIT. This review identifies some of the most common etiological risk factors of colon cancer in these nations and evaluates the existing epidemiological evidence. The main risk factors which were found to be prevalent in NIT include: lifestyle factors such as physical inactivity, obesity and abdominal adiposity, alcohol consumption and cigarette smoking; dietary factors such as fatty food and red meat consumption. Protective factors included white meat and fiber consumption. Several studies found to have significantly higher rates of colon cancer among the young population (<40 years old. There appears to be a quantitative and qualitative increase in risk to relatives of patients diagnosed at a young age compared with those diagnosed later in life, at least part of which is likely to be the result of a hereditary susceptibility. Close relatives of patients with colon cancer are at an increased risk of developing a colon cancer. Close relatives of early onset cases warrant more intensive endoscopic screening and at an earlier age than relatives of patients diagnosed at older ages. Furthermore, these suggest the existence of genetic predispositions in these nations which need to be investigated further and have implications for screening programs. In conclusion, public health awareness campaigns promoting prevention of modifiable risk factors and screening initiatives with guidelines suited to the age-specific incidence rates of NIT are needed very urgently.

  18. DPOI: Distributed software system development platform for ocean information service (United States)

    Guo, Zhongwen; Hu, Keyong; Jiang, Yongguo; Sun, Zhaosui


    Ocean information management is of great importance as it has been employed in many areas of ocean science and technology. However, the developments of Ocean Information Systems (OISs) often suffer from low efficiency because of repetitive work and continuous modifications caused by dynamic requirements. In this paper, the basic requirements of OISs are analyzed first, and then a novel platform DPOI is proposed to improve development efficiency and enhance software quality of OISs by providing off-the-shelf resources. In the platform, the OIS is decomposed hierarchically into a set of modules, which can be reused in different system developments. These modules include the acquisition middleware and data loader that collect data from instruments and files respectively, the database that stores data consistently, the components that support fast application generation, the web services that make the data from distributed sources syntactical by use of predefined schemas and the configuration toolkit that enables software customization. With the assistance of the development platform, the software development needs no programming and the development procedure is thus accelerated greatly. We have applied the development platform in practical developments and evaluated its efficiency in several development practices and different development approaches. The results show that DPOI significantly improves development efficiency and software quality.

    Full Text Available Christine Cohen, Thomas Kampel, Henk Verloo Department Ra&D, La Source School of Nursing Sciences, University of Applied Sciences and Arts Western Switzerland, Lausanne, Switzerland Background: Aging at home rather than in an institution is now considered the gold standard. Public health figures document an important demographic transition to an increasingly elderly society. At the same time, this is accompanied by the emergence of significant numbers of innovative technologies to help and support home-dwelling older adults in declining health who wish to remain at home.Study aim: To explore the acceptability of intelligent wireless sensor system (IWSS among home-dwelling older adults in rapidly detecting their health issues.Methods: Data were sourced from a pilot 3-month randomized clinical trial that involved 34 older patients in the experimental group (EG using an IWSS to rapidly detect falls and other health issues at home. The effectiveness of the IWSS was assessed by comparing it to participants’ functional and cognitive status, as measured both before and after the trial. The Resident Assessment Instrument for Home Care, Confusion Assessment Method, Cognitive Performance Scale, Geriatric Depression Scale, and Informed Questionnaire on Cognitive Decline in the Elderly were used for the assessments. Acceptability of the IWSS was explored at the end of the study.Results: Both older adults and their informal caregivers considered the performance and usefulness of the IWSS intervention to be low to moderate. A majority of the participants were unsatisfied with its ease of use and found multiple obstacles in using and having an intention to use the IWSS. However, their informal caregivers were more satisfied with the program and gave higher scores for usefulness, ease of use, and intention to use IWSS technology.Conclusion: The IWSS displayed low-to-moderate acceptability among the older participants and their informal caregivers.

  20. An Ethnographically Informed Participatory Design of Primary Healthcare Information Technology in a Developing Country Setting. (United States)

    Shidende, Nima Herman; Igira, Faraja Teddy; Mörtberg, Christina Margaret


    Ethnography, with its emphasis on understanding activities where they occur, and its use of qualitative data gathering techniques rich in description, has a long tradition in Participatory Design (PD). Yet there are limited methodological insights in its application in developing countries. This paper proposes an ethnographically informed PD approach, which can be applied when designing Primary Healthcare Information Technology (PHIT). We use findings from a larger multidisciplinary project, Health Information Systems Project (HISP) to elaborate how ethnography can be used to facilitate participation of health practitioners in developing countries settings as well as indicating the importance of ethnographic approach to participatory Health Information Technology (HIT) designers. Furthermore, the paper discusses the pros and cons of using an ethnographic approach in designing HIT.

    radiation and provided the first step in the development of a self contained THz HFTS for rapid electron bunch shape analysis. Our first experiments confirmed the idea and as a side result made possible a completely new bunch length monitor eliminating any need for an external laser since only radiation produced by the bunch itself is involved. A more advanced instrument was designed to use the incoherent visible radiation pulse from the synchrotron source for sampling the THz interference pattern. It has been built and the first tests are to be conducted in April 2011 at the Jefferson FEL facility.

  2. Developing an informational tool for ethical engagement in medical tourism. (United States)

    Adams, Krystyna; Snyder, Jeremy; Crooks, Valorie A; Johnston, Rory


    Medical tourism, the practice of persons intentionally travelling across international boundaries to access medical care, has drawn increasing attention from researchers, particularly in relation to potential ethical concerns of this practice. Researchers have expressed concern for potential negative impacts to individual safety, public health within both countries of origin for medical tourists and destination countries, and global health equity. However, these ethical concerns are not discussed within the sources of information commonly provided to medical tourists, and as such, medical tourists may not be aware of these concerns when engaging in medical tourism. This paper describes the methodology utilized to develop an information sheet intended to be disseminated to Canadian medical tourists to encourage contemplation and further public discussion of the ethical concerns in medical tourism. The methodology for developing the information sheet drew on an iterative process to consider stakeholder feedback on the content and use of the information sheet as it might inform prospective medical tourists' decision making. This methodology includes a literature review as well as formative research with Canadian public health professionals and former medical tourists. The final information sheet underwent numerous revisions throughout the formative research process according to feedback from medical tourism stakeholders. These revisions focused primarily on making the information sheet concise with points that encourage individuals considering travelling for medical tourism to do further research regarding their safety both within the destination country, while travelling, and once returning to Canada, and the potential impacts of their trip on third parties. This methodology may be replicated for the development of information sheets intending to communicate ethical concerns of other practices to providers or consumers of a certain service.

  3. Rapid HIV testing for developing countries: the challenge of false-negative tests (United States)

    Yogev, Ram


    It is a common practice in resource-constrained countries to accept two positive rapid HIV antibody test results as diagnostic for HIV infection. Because these tests are inexpensive and results are obtained quickly, they are recommended by the WHO to "scale-up" HIV testing to increase the number of people tested. The negative predictive value of rapid HIV tests is so high that negative results are considered conclusive despite the fact that false-negative results can occur in several situations. While the specificity and sensitivity of rapid HIV tests in resource-rich countries is acceptable, there are only limited data about their performance in resource-constrained countries. The challenges of rapid HIV testing in these situations will be discussed.

    The production of recombinant monoclonal antibodies in mammalian cell culture is of high priority in research and medical fields. A critical step in this process is the isolation of the antigen-binding domain sequences of antibodies possessing the desired properties. Many different techniques have been described to achieve this goal, but all have shortcomings; most techniques have problems with robustness, are time-consuming and costly, or have complications in the transfer from isolation to production phase. Here, we report a novel HybriFree technology for the development of monoclonal antibodies from different species that is robust, rapid, inexpensive and flexible and can be used for the subsequent production of antibodies in mammalian cell factories. HybriFree technology is illustrated herein via detailed examples of isolating mouse, rabbit and chicken monoclonal antibody sequences from immunized animals. Starting from crude spleen samples, antigen capturing of specific B-cells is performed initially. cDNA of antibody variable domains is amplified from the captured cells and used a source material for simple and rapid restriction/ligation free cloning of expression vector library in order to produce scFv-Fc or intact IgG antibodies. The vectors can be directly used for screening purposes as well as for the subsequent production of the developed monoclonal antibodies in mammalian cell culture. The antibodies isolated by the method have been shown to be functional in different immunoassays, including ELISA, immunofluorescence and Western blot. In addition, we demonstrate that by using a modified method including a negative selection step, we can isolate specific antibodies targeting the desired epitope and eliminate antibodies directed to undesired off-targets. HybriFree can be used for the reliable development of monoclonal antibodies and their subsequent production in mammalian cells. This simple protocol requires neither the culturing of B-cells nor single

  5. The Disparity Information and Communication Technology for Developing Countries has in the Delivery of Healthcare Information. (United States)

    Chhanabhai, Prajesh N; Holt, Alec


    Information and Communication Technologies (ICT) have merged into the world of healthcare slowly but surely. However, the marriage between the use of technology and its full impact in the health sector has not been fully realised. The focus of this paper is to highlight the impact of ICT on revolutionising access to healthcare information and thus quality of health for populations of the developing world. This paper highlights on the importance of being able to access health information and how traditional media methods have been utilised to allow this within a developing country setting, highlighting the clear digital divide. The paper then addresses the impact of convergent communication technologies and mobile technologies in providing a means of addressing existing healthcare problems within a developing country setting.

  6. City Sustainable Development Evaluation Based on Hesitant Multiplicative Fuzzy Information

    Directory of Open Access Journals (Sweden)

    Xiaorong He


    Full Text Available Sustainable development evaluation is the basis of city sustainable development research, and effective evaluation is the foundation for guiding the formulation and implementation of sustainable development strategy. In this paper, we provided a new city sustainable development evaluation method called hesitant multiplicative fuzzy TODIM (HMF-TODIM. The main advantage of this method is that it can deal with the subjective preference information of the decision-makers. The comparison study of existing methods and HMF-TODIM is also carried out. Additionally, real case analysis is presented to show the validity and superiority of the proposed method. Research results in this paper can provide useful information for the construction of sustainable cities.

  8. Development of morphing algorithms for Histfactory using information geometry

    Energy Technology Data Exchange (ETDEWEB)

    Bandyopadhyay, Anjishnu; Brock, Ian [University of Bonn (Germany); Cranmer, Kyle [New York University (United States)


    Many statistical analyses are based on likelihood fits. In any likelihood fit we try to incorporate all uncertainties, both systematic and statistical. We generally have distributions for the nominal and ±1 σ variations of a given uncertainty. Using that information, Histfactory morphs the distributions for any arbitrary value of the given uncertainties. In this talk, a new morphing algorithm will be presented, which is based on information geometry. The algorithm uses the information about the difference between various probability distributions. Subsequently, we map this information onto geometrical structures and develop the algorithm on the basis of different geometrical properties. Apart from varying all nuisance parameters together, this algorithm can also probe both small (< 1 σ) and large (> 2 σ) variations. It will also be shown how this algorithm can be used for interpolating other forms of probability distributions.

  9. Planar array stack design aided by rapid prototyping in development of air-breathing PEMFC (United States)

    Chen, Chen-Yu; Lai, Wei-Hsiang; Weng, Biing-Jyh; Chuang, Huey-Jan; Hsieh, Ching-Yuan; Kung, Chien-Chih

    The polymer electrolyte membrane fuel cell (PEMFC) is one of the most important research topics in the new and clean energy area. The middle or high power PEMFCs can be applied to the transportation or the distributed power system. But for the small power application, it is needed to match the power requirement of the product generally. On the other hand, the direct methanol fuel cell (DMFC) is one of the most common type that researchers are interested in, but recently the miniature or the micro-PEMFCs attract more attention due to their advantages of high open circuit voltage and high power density. The objective of this study is to develop a new air-breathing planar array fuel cell stacked from 10 cells made by rapid prototyping technology which has potential for fast commercial design, low cost manufacturing, and even without converters/inverters for the system. In this paper, the main material of flow field plates is acrylonitrile-butadiene-styrene (ABS) which allows the fuel cell be mass-manufactured by plastic injection molding technology. The rapid prototyping technology is applied to construct the prototype and verify the practicability of the proposed stack design. A 10-cell air-breathing miniature PEMFC stack with a volume of 6 cm × 6 cm × 0.9 cm is developed and tested. Its segmented membrane electrode assembly (MEA) is designed with the active surface area of 1.3 cm × 1.3 cm in each individual MEA. The platinum loading at anode and cathode are 0.2 mg cm -2 and 0.4 mg cm -2, respectively. Results show that the peak power densities of the parallel connected and serial connected stack are 99 mW cm -2 at 0.425 V and 92 mW cm -2 at 4.25 V, respectively under the conditions of 70 °C relative saturated humidity (i.e., dew point temperature), ambient temperature and free convection air. Besides, the stack performance is increased under forced convection. If the cell surface air is blown by an electric fan, the peak power densities of parallel connected and

    Porous hydroxyapatite (HA) scaffold has great potential in bone tissue engineering applications. A new method to fabricate macroporous calcium phosphate (CP) scaffold via microwave irradiation, followed by conventional sintering to form HA scaffold was developed. Incorporation of trisodium citrate dihydrate and citric acid in the CP mixture gave macroporous scaffolds upon microwave rapid drying. In this work, a mixture of {beta}-tricalcium phosphate ({beta}-TCP), calcium carbonate (CaCO{sub 3}), trisodium citrate dihydrate, citric acid and double distilled de-ionised water (DDI) was exposed to microwave radiation to form a macroporous structure. Based on gross eye examinations, addition of trisodium citrate at 30 and 40 wt.% in the CP mixture ({beta}-TCP and CaCO{sub 3}) without citric acid indicates increasing order of pore volume where the highest porosity yield was observed at 40 wt.% of trisodium citrate addition and the pore size was detected at several millimeters. Therefore, optimization of pore size was performed by adding 3-7 wt.% of citric acid in the CP mixture which was separately mixed with 30 and 40 wt.% of trisodium citrate for comparison purposes. Fabricated scaffolds were calcined at 600 deg. C and washed with DDI water to remove the sodium hydroxycarbonate and sintered at 1250 deg. C to form HA phase as confirmed in the X-ray diffraction (XRD) results. Based on Archimedes method, HA scaffolds prepared from 40 wt.% of trisodium citrate with 3-7 wt.% of citric acid added CP mixture have an open and interconnected porous structure ranging from 51 to 53 vol.% and observation using Scanning electron microscope (SEM) showed the pore size distribution between 100 and 500 {mu}m. The cytotoxicity tests revealed that the porous HA scaffolds have no cytotoxic potential on MG63 osteoblast-like cells which might allow for their use as biomaterials.

  15. Development of a loop-mediated isothermal amplification assay for rapid detection of capripoxviruses. (United States)

    Das, Amaresh; Babiuk, Shawn; McIntosh, Michael T


    Sheep pox (SP), goat pox (GP), and lumpy skin disease (LSD), caused by capripoxviruses (CaPVs), are economically important diseases of sheep, goats, and cattle, respectively. Here, we report the development of a loop-mediated isothermal amplification (LAMP) assay for rapid detection of CaPVs. LAMP primers were designed to target a conserved gene encoding the poly(A) polymerase small subunit (VP39) of CaPVs. Hydroxynaphthol blue (HNB) was incorporated to monitor assay progress by color change from violet when negative to sky blue when positive, and results were verified by agarose gel electrophoresis. The LAMP assay was shown to be highly specific for CaPVs, with no apparent cross-reactivity to other related viruses (near neighbors) or viruses that cause similar clinical signs (look-a-like viruses). The performance of LAMP was compared to that of a highly sensitive quantitative real-time PCR (qPCR) assay. LAMP and qPCR exhibited similar analytical sensitivities, with limits of detection of 3 and 8 viral genome copies, respectively. Diagnostic specificity was assessed on 36 negative specimens, including swabs and EDTA blood from control sheep, goats, and cattle. Diagnostic sensitivity was assessed on 275 specimens, including EDTA blood, swabs, and tissues from experimentally infected sheep, goats, and cattle. Overall agreement on diagnostic test results between the two assays was 90 to 95% for specificity and 89 to 100% for sensitivity. The LAMP assay described in this report is simple to use, inexpensive, highly sensitive, and particularly well suited for the diagnosis of capripox in less well equipped laboratories and in rural settings where resources are limited.

  16. Development of a Multiplex PCR Assay for Rapid Molecular Serotyping of Haemophilus parasuis (United States)

    Peters, Sarah E.; Wang, Jinhong; Hernandez-Garcia, Juan; Weinert, Lucy A.; Luan, Shi-Lu; Chaudhuri, Roy R.; Angen, Øystein; Aragon, Virginia; Williamson, Susanna M.; Langford, Paul R.; Rycroft, Andrew N.; Wren, Brendan W.; Maskell, Duncan J.; Tucker, Alexander W.


    Haemophilus parasuis causes Glässer's disease and pneumonia in pigs. Indirect hemagglutination (IHA) is typically used to serotype this bacterium, distinguishing 15 serovars with some nontypeable isolates. The capsule loci of the 15 reference strains have been annotated, and significant genetic variation was identified between serovars, with the exception of serovars 5 and 12. A capsule locus and in silico serovar were identified for all but two nontypeable isolates in our collection of >200 isolates. Here, we describe the development of a multiplex PCR, based on variation within the capsule loci of the 15 serovars of H. parasuis, for rapid molecular serotyping. The multiplex PCR (mPCR) distinguished between all previously described serovars except 5 and 12, which were detected by the same pair of primers. The detection limit of the mPCR was 4.29 × 105 ng/μl bacterial genomic DNA, and high specificity was indicated by the absence of reactivity against closely related commensal Pasteurellaceae and other bacterial pathogens of pigs. A subset of 150 isolates from a previously sequenced H. parasuis collection was used to validate the mPCR with 100% accuracy compared to the in silico results. In addition, the two in silico-nontypeable isolates were typeable using the mPCR. A further 84 isolates were analyzed by mPCR and compared to the IHA serotyping results with 90% concordance (excluding those that were nontypeable by IHA). The mPCR was faster, more sensitive, and more specific than IHA, enabling the differentiation of 14 of the 15 serovars of H. parasuis. PMID:26424843

  17. Rapid development of cyanobacterial crust in the field for combating desertification. (United States)

    Park, Chan-Ho; Li, Xin Rong; Zhao, Yang; Jia, Rong Liang; Hur, Jae-Seoun


    Desertification is currently a major concern, and vast regions have already been devastated in the arid zones of many countries. Combined application of cyanobacteria with soil fixing chemicals is a novel method of restoring desertified areas. Three cyanobacteria, Nostoc sp. Vaucher ex Bornet & Flahault, Phormidium sp. Kützing ex Gomont and Scytonema arcangeli Bornet ex Flahault were isolated and tested in this study. Tacki-SprayTM (TKS7), which consists of bio-polysaccharides and tackifiers, was used as a soil fixing agent. In addition, superabsorbent polymer (SAP) was applied to the soil as a water-holding material and nutrient supplement. Application of cyanobacteria with superabsorbent polymer and TKS7 (CST) remarkably improved macro-aggregate stability against water and erodibility against wind after 12 months of inoculation when compared to the control soil. The mean weight diameter and threshold friction velocity of the CST treated soil were found to be 75% and 88% of those of the approximately 20-year-old natural cyanobacterial crust (N-BSC), respectively, while these values were 68% and 73% of those of the N-BSC soil after a single treatment of cyanobacteria alone (CY). Interestingly, biological activities of CST were similar to those of CY. Total carbohydrate contents, cyanobacterial biomass, microbial biomass, soil respiration, carbon fixation and effective quantum yield of CST treated soil were enhanced by 50-100% of the N-BSC, while those of control soil were negligible. Our results suggest that combined application of cyanobacteria with soil fixing chemicals can rapidly develop cyanobacterial crust formation in the field within 12 months. The physical properties and biological activities of the inoculated cyanobacterial crust were stable during the study period. The novel method presented herein serves as another approach for combating desertification in arid regions.

  18. Activation of Notch3 in Glomeruli Promotes the Development of Rapidly Progressive Renal Disease. (United States)

    El Machhour, Fala; Keuylian, Zela; Kavvadas, Panagiotis; Dussaule, Jean-Claude; Chatziantoniou, Christos


    Notch3 expression is found in the glomerular podocytes of patients with lupus nephritis or focal segmental GN but not in normal kidneys. Here, we show that activation of the Notch3 receptor in the glomeruli is a turning point inducing phenotypic changes in podocytes promoting renal inflammation and fibrosis and leading to disease progression. In a model of rapidly progressive GN, Notch3 expression was induced by several-fold in podocytes concurrently with disease progression. By contrast, mice lacking Notch3 expression were protected because they exhibited less proteinuria, uremia, and inflammatory infiltration. Podocyte outgrowth from glomeruli isolated from wild-type mice during the early phase of the disease was higher than outgrowth from glomeruli of mice lacking Notch3. In vitro studies confirmed that podocytes expressing active Notch3 reorganize their cytoskeleton toward a proliferative/migratory and inflammatory phenotype. We then administered antisense oligodeoxynucleotides targeting Notch3 or scramble control oligodeoxynucleotides in wild-type mice concomitant to disease induction. Both groups developed chronic renal disease, but mice injected with Notch3 antisense had lower values of plasma urea and proteinuria and inflammatory infiltration. The improvement of renal function was accompanied by fewer deposits of fibrin within the glomeruli and by decreased peritubular inflammation. Finally, abnormal Notch3 staining was observed in biopsy samples of patients with crescentic GN. These results demonstrate that abnormal activation of Notch3 may be involved in the progression of renal disease by promoting migratory and proinflammatory pathways. Inhibiting Notch3 activation could be a novel, promising approach to treat GN. Copyright © 2015 by the American Society of Nephrology.

  19. Birth weight and delivery practice in a Vietnamese rural district during 12 year of rapid economic development. (United States)

    Nguyen, Huong Thu; Eriksson, Bo; Tran, Toan Khanh; Nguyen, Chuc Thi Kim; Ascher, Henry


    Since the Doi Moi reform 1986 economic conditions in Vietnam have changed significantly and positive health and health care developments have been observed. International experience shows that improved economic conditions in a country can reduce the risk of perinatal mortality, decrease the risk of low birth weight and increase the mean birth weight in newborns. The Health and Demographic Surveillance Site (HDSS) FilaBavi in Bavi district outside Hanoi city has been operational since 1999. An open cohort of more than 12,000 households (52,000 persons) has been followed primarily with respect to demography, economy and education. The aim of this research is to study trends in birth weight as well as birth and delivery practices over the time period 1999-2010 in FilaBavi in relation to the social and economic development. Information about birth weight, sex, place and method of delivery, mother's age and education as well as household economy of 10,114 children, born from 1999 to 2010, was obtained from the routine data collection in the HDSS. Over the study period the mean birth weight remained at the same level, about 3,100 g, in spite of increased economic resources and technology development. At the individual child level we found associations between birth weight and household economy as well as the education of the mother. Hospital delivery increased from about 35% to 65% and the use of Caesarian section increased from 2.6% to 10.1%. During the twelve years studied, household income as well as the use of modern technology increased rapidly. In spite of that, the mean and variation of birth weight did not change systematically. It is suggested that increasing gaps in economic conditions and misallocation of resources, possibly to overuse of technology, are partly responsible.

  20. Development of a self-contained device for rapid detection of volatile impurities in the oil system of a turbine (United States)

    Starostin, A. A.; Shangin, V. V.; Bukhman, V. G.; Volosnikov, D. V.; Skripov, P. V.


    The research is devoted to development of a self-contained device for rapid detection of volatile impurities in the oil system of a turbine and testing it using the operating equipment. The device consists of a remote sensor, whose sensitive element is a 3-5-mm long wire probe 20 microns in diameter, and a measurement unit that comprises a microcontroller with a set of peripherals. The design of the device enables automation of the measurement procedure with a minimum number of preset settings and real-time output of information to the operator console. The software of the device provides two-stage pulse heating of the wire probe and a resistance temperature detector. The two-stage mode proves to be the most sensitive to appearance in the system of moisture, including its trace amounts. The characteristic time of the heating is of the order of 10 ms. The measurement procedure is based on a method that consists in automatic search for spontaneous boiling-up temperature of the oil accompanied by a characteristic response signal. The results were interpreted by formal correlation of the measured values with an array of calibration data obtained in similar experiments with well-defined oil samples. An experimental method for application of the device has been developed that takes into account technological factors, such as comparatively high values of the flow rate and the temperature of the oil in locations of the oil drain from bearings, the variability of these values, and the variety of noise types that accompany the operation of the thermal power equipment that complicate the online measurements. Tests of the device were carried out in locations of oil drain from supporting bearings. The test results have demonstrated the possibility of applying the device directly in the oil system of a turbine and provided a practical basis for development of a system of multipoint control of the technological scheme in real time.

Radioanalytical techniques are well established for radionuclides measurement, however, they are slow and labor intensive, requiring extensive radiochemical separations and purification prior to analysis. With these limitations of current methods, there is great interest for a new technique to rapidly process samples. This dissertation describes a new analyte extraction medium called Polymer Ligand Film (PLF) developed to rapidly extract radionuclides. Polymer Ligand Film is a polymer medium with ligands incorporated in its matrix that selectively and rapidly extract analytes from a solution. The main focus of the new technique is to shorten and simplify the procedure necessary to chemically isolate radionuclides for determination by alpha spectrometry or beta counting. Five different ligands were tested for plutonium extraction: bis(2-ethylhexyl) methanediphosphonic acid (H2DEH[MDP]), di(2-ethyl hexyl) phosphoric acid (HDEHP), trialkyl methylammonium chloride (Aliquat-336), 4,4'(5')-di-t-butylcyclohexano 18-crown-6 (DtBuCH18C6), and 2-ethylhexyl 2-ethylhexylphosphonic acid (HEH[EHP]). The ligands that were effective for plutonium extraction further studied for uranium extraction. The plutonium recovery by PLFs has shown dependency on nitric acid concentration and ligand to total mass ratio. H2DEH[MDP] PLFs performed best with 1:10 and 1:20 ratio PLFs. 50.44% and 47.61% of plutonium were extracted on the surface of PLFs with 1M nitric acid for 1:10 and 1:20 PLF, respectively. HDEHP PLF provided the best combination of alpha spectroscopy resolution and plutonium recovery with 1:5 PLF when used with 0.1M nitric acid. The overall analyte recovery was lower than electrodeposited samples, which typically has recovery above 80%. However, PLF is designed to be a rapid field deployable screening technique and consistency is more important

  17. RAPID COMMUNICATION: Nerve growth factor influences cleavage rate and embryo development in sheep. (United States)

    Crispo, M; Dos Santos-Neto, P C; Vilariño, M; Mulet, A P; de León, A; Barbeito, L; Menchaca, A


    Recent information about Nerve growth factor (NGF), a protein traditionally associated to the nervous system that regulates survival and maturation of developing neurons, suggests that it may exert action also on different levels in the reproductive system. The aim of this study was to evaluate the effect of NGF added during in vitro oocyte maturation, fertilization or in vitro embryo development in sheep. Nerve growth factor was supplemented to the culture medium at 0, 100, or 1,000 ng/mL, during either in vitro maturation (Exp. 1), in vitro fertilization (Exp. 2), or in vitro culture (Exp. 3). In addition, NGF mRNA expression was determined in cumulus cells and oocytes. Nerve growth factor induced early cleavage when added during oocyte maturation or fertilization, improved embryo development when added during fertilization, and had no significant effect when added during embryo culture. In general, the effect was more evident with 100 rather than 1,000 ng/mL (P growth factor on oocyte maturation and mainly on the fertilization process.

  18. Sea-ice information co-management: Planning for sustainable multiple uses of ice-covered seas in a rapidly changing Arctic (United States)

    Eicken, H.; Lovecraft, A. L.


    A thinner, less extensive and more mobile summer sea-ice cover is a major element and driver of Arctic Ocean change. Declining summer sea ice presents Arctic stakeholders with substantial challenges and opportunities from the perspective of sustainable ocean use and derivation of sea-ice or ecosystem services. Sea-ice use by people and wildlife as well as its role as a major environmental hazard focuses the interests and concerns of indigenous hunters and Arctic coastal communities, resource managers and the maritime industry. In particular, rapid sea-ice change and intensifying offshore industrial activities have raised fundamental questions as to how best to plan for and manage multiple and increasingly overlapping ocean and sea ice uses. The western North American Arctic - a region that has seen some of the greatest changes in ice and ocean conditions in the past three decades anywhere in the North - is the focus of our study. Specifically, we examine the important role that relevant and actionable sea-ice information can play in allowing stakeholders to evaluate risks and reconcile overlapping and potentially competing interests. Our work in coastal Alaska suggests that important prerequisites to address such challenges are common values, complementary bodies of expertise (e.g., local or indigenous knowledge, engineering expertise, environmental science) and a forum for the implementation and evaluation of a sea-ice data and information framework. Alongside the International Polar Year 2007-08 and an associated boost in Arctic Ocean observation programs and platforms, there has been a movement towards new governance bodies that have these qualities and can play a central role in guiding the design and optimization of Arctic observing systems. To help further the development of such forums an evaluation of the density and spatial distribution of institutions, i.e., rule sets that govern ocean use, as well as the use of scenario planning and analysis can serve as

    Hayden, Jill A; Killian, Lara; Zygmunt, Austin; Babineau, Jessica; Martin-Misener, Ruth; Jensen, Jan L; Carter, Alix J


    The aim of this rapid knowledge synthesis was to provide relevant research evidence to inform the implementation of a new health service in Nova Scotia, Canada: Collaborative Emergency Centres (CECs). CECs propose to deliver both primary and urgent care to rural populations where traditional delivery is a challenge. This paper reports on the methods used in a rapid knowledge synthesis project to provide timely evidence to policy makers about this novel healthcare delivery model. We used a variety of methods, including a jurisdictional/scoping review, modified systematic review methodologies, and integrated knowledge translation. We scanned publicly available information about similar centres across our country to identify important components of CECs and CEC-type models to operationalize the definition of a CEC. We conducted literature searches in PubMed, CINAHL, and EMBASE, and in the grey literature, to identify evidence on the key structures and processes and effectiveness of CEC-type models of care delivery. Our searches were limited to published systematic reviews. The research team facilitated two integrated knowledge translation workshops during the project to engage stakeholders, to refine the research goals and objectives, and to share interim and final results. Citations and included articles were categorized by whether they addressed the CEC model or component structures and processes. Data and key messages were extracted from these reviews to inform implementation. CEC-type models have limited peer-reviewed evidence available; no peer-reviewed studies on CECs as a standalone healthcare model were found. As a result, our evidence search and synthesis was revised to focus on core CEC-type structures and processes, prioritized through consensus methods with the stakeholder group, and resulted in provision of a meaningful evidence synthesis to help inform the development and implementation of CECs in Nova Scotia. A variety of methods and partnership with

    Calik, Elif; Atilla, Rıdvan; Kaya, Hilal; Aribaş, Alirıza; Cengiz, Hakan; Dicle, Oğuz


    This study aims to improve a medical module which provides a real-time medical information flow about pre-hospital processes that gives health care in disasters; transferring, storing and processing the records that are in electronic media and over internet as a part of disaster information systems. In this study which is handled within the frame of providing information flow among professionals in a disaster case, to supply the coordination of healthcare team and transferring complete information to specified people at real time, Microsoft Access database and SQL query language were used to inform database applications. System was prepared on Microsoft .Net platform using C# language. Disaster information system-medical module was designed to be used in disaster area, field hospital, nearby hospitals, temporary inhabiting areas like tent city, vehicles that are used for dispatch, and providing information flow between medical officials and data centres. For fast recording of the disaster victim data, accessing to database which was used by health care professionals was provided (or granted) among analysing process steps and creating minimal datasets. Database fields were created in the manner of giving opportunity to enter new data and search old data which is recorded before disaster. Web application which provides access such as data entry to the database and searching towards the designed interfaces according to the login credentials access level. In this study, homepage and users' interfaces which were built on database in consequence of system analyses were provided with web site to the user access. With this study, a recommendation was made about how to use disaster-based information systems in the field of health. Awareness has been developed about the fact that disaster information system should not be perceived only as an early warning system. Contents and the differences of the health care practices of disaster information systems were

  1. Unconventional natural gas development and public health: toward a community-informed research agenda. (United States)

    Korfmacher, Katrina Smith; Elam, Sarah; Gray, Kathleen M; Haynes, Erin; Hughes, Megan Hoert


    Unconventional natural gas development (UNGD) using high-volume horizontal hydraulic fracturing ("fracking") has vastly increased the potential for domestic natural gas production in recent years. However, the rapid expansion of UNGD has also raised concerns about its potential impacts on public health. Academics and government agencies are developing research programs to explore these concerns. Community involvement in activities such as planning, conducting, and communicating research is widely recognized as having an important role in promoting environmental health. Historically, however, communities most often engage in research after environmental health concerns have emerged. This community information needs assessment took a prospective approach to integrating community leaders' knowledge, perceptions, and concerns into the research agenda prior to initiation of local UNGD. We interviewed community leaders about their views on environmental health information needs in three states (New York, North Carolina, and Ohio) prior to widespread UNGD. Interviewees emphasized the cumulative, long-term, and indirect determinants of health, as opposed to specific disease outcomes. Responses focused not only on information needs, but also on communication and transparency with respect to research processes and funding. Interviewees also prioritized investigation of policy approaches to effectively protect human health over the long term. Although universities were most often cited as a credible source of information, interviewees emphasized the need for multiple strategies for disseminating information. By including community leaders' concerns, insights, and questions from the outset, the research agenda on UNGD is more likely to effectively inform decision making that ultimately protects public health.

  2. Essential Function of Dicer in Resolving DNA Damage in the Rapidly Dividing Cells of the Developing and Malignant Cerebellum

    Directory of Open Access Journals (Sweden)

    Vijay Swahari


    Full Text Available Maintenance of genomic integrity is critical during neurodevelopment, particularly in rapidly dividing cerebellar granule neuronal precursors that experience constitutive replication-associated DNA damage. As Dicer was recently recognized to have an unexpected function in the DNA damage response, we examined whether Dicer was important for preserving genomic integrity in the developing brain. We report that deletion of Dicer in the developing mouse cerebellum resulted in the accumulation of DNA damage leading to cerebellar progenitor degeneration, which was rescued with p53 deficiency; deletion of DGCR8 also resulted in similar DNA damage and cerebellar degeneration. Dicer deficiency also resulted in DNA damage and death in other rapidly dividing cells including embryonic stem cells and the malignant cerebellar progenitors in a mouse model of medulloblastoma. Together, these results identify an essential function of Dicer in resolving the spontaneous DNA damage that occurs during the rapid proliferation of developmental progenitors and malignant cells.

  3. Co-design of RAD and ETHICS methodologies: a combination of information system development methods (United States)

    Nasehi, Arezo; Shahriyari, Salman


    Co-design is a new trend in the social world which tries to capture different ideas in order to use the most appropriate features for a system. In this paper, co-design of two information system methodologies is regarded; rapid application development (RAD) and effective technical and human implementation of computer-based systems (ETHICS). We tried to consider the characteristics of these methodologies to see the possibility of having a co-design or combination of them for developing an information system. To reach this purpose, four different aspects of them are analyzed: social or technical approach, user participation and user involvement, job satisfaction, and overcoming change resistance. Finally, a case study using the quantitative method is analyzed in order to examine the possibility of co-design using these factors. The paper concludes that RAD and ETHICS are appropriate to be co-designed and brings some suggestions for the co-design.

    Full Text Available Objective - The main purpose of this study was to understand the information research process of experienced online information researchers in a variety of disciplines, gather their ideas for improvement and as part of this to validate a proposed research framework for use in future development of Ontario’s Scholars Portal.Methods - This was a qualitative research study in which sixty experienced online information researchers participated in face-to-face workshops that included a collaborative design component. The sessions were conducted and recorded by usability specialists who subsequently analyzed the data and identified patterns and themes.Results - Key themes included the similarities of the information research process across all disciplines, the impact of interdisciplinarity, the social aspect of research and opportunities for process improvement. There were many specific observations regarding current and ideal processes. Implications for portal development and further research included: supporting a common process while accommodating user-defined differences; supporting citation chaining practices with new opportunities for data linkage and granularity; enhancing keyword searching with various types of intervention; exploring trusted social networks; exploring new mental models for data manipulation while retaining traditional objects; improving citation and document management. Conclusion – The majority of researchers in the study had almost no routine in their information research processes, had developed few techniques to assist themselves and had very little awareness of the tools available to help them. There are many opportunities to aid researchers in the research process that can be explored when developing scholarly research portals. That development will be well guided by the framework ‘discover, gather, synthesize, create, share.’

    Ali Bagherinia


    Full Text Available Information for tourism and transportation industries is as vital as blood for the human life. According to tourism experts, Iran ranks among ten top countries with the most touristy attractions. Iran’s share from the income of international tourism markets was about 1 unit from a total of 700 units in the year 2000. A major problem on the way of tourism development is the weakness of information systems and their supporters. This has led to providing insufficient information on the attractions and capabilities and service preparation, much lower than expected level. This is while for tourism planning and dynamism exact and updated information system is needed; IT is very effective in this respect. IT can play a great role in managing, planning, and marketing for tourism development. Emphasizing IT usage in tourism, some main applications of this technology like fast, cheap, and on time informing of electronic systems for service provision such as computer reservation systems (CRSs, global distribution systems (GDSs and Internet have been regarded in this paper.

    Sohn, Jae Min; Ko, Young Cheol; Song, Tai Gil [Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)


    Korea has become a technically independent nuclear country and has grown into an exporter of nuclear technologies. Thus, nuclear facilities are increasing in significance at KAERI (Korea Atomic Energy Research Institute), and it is time to address the nuclear safety. The importance of nuclear safety cannot be overemphasized. Therefore, a management system is needed urgently to manage the safety of nuclear facilities and to enhance the efficiency of nuclear information. We have established ISP (Information Strategy Planning) for the Integrated Information System of nuclear facility and safety management. The purpose of this paper is to develop a management system for nuclear safety. Therefore, we developed the Advanced Nuclear Safety Information Management system (hereinafter referred to as the 'ANSIM system'). The ANSIM system has been designed and implemented to computerize nuclear safety information for standardization, integration, and sharing in real-time. Figure 1 shows the main home page of the ANSIM system. In this paper, we describe the design requirements, contents, configurations, and utilizations of the ANSIM system

  8. INFORM: development of information management and decision support systems for High Dependency Environments. (United States)

    Bowes, C L; Ambroso, C; Carson, E R; Chambrin, M C; Cramp, D; Gilhooly, K; Groth, T; Hunter, J R; Kalli, S; Leaning, M L

    The long-term aim in the INFORM Project is to develop, evaluate and implement a new generation of Information Systems for hospital High Dependency Environments (HDE-Intensive Care Units, Neonatal Units, Burns Units. Operating and Recovery Rooms, and other specialised areas). The distinguishing feature of the HDE is the very large amount of data that is collected through monitors and paper records about the state of critically ill patients; this has made the role of the staff a technical one in addition to a caring one. The INFORM System will integrate Decision Support with on-line, off-line and observed patient data and, in addition, will incorporate and integrate unit management features. In the Exploratory Phase of the Project, functional requirements have been set out. These are based on four components: conceptual model of the HDE; evaluation of existing HDE Information Systems; development of a novel software architecture using a Knowledge-Based Systems (KBS) methodology, and based on a critical review of KBS applied to the HDE: monitoring of appropriate leading-edge technological developments. The conceptual model has two components: a patient-related information model, and a department-related cost model. The patient-related model is identifying key and difficult areas of decision making. A key aspect of INFORM is integration of clinical Decision Support for these areas into the Information System through a layered software architecture. The lower layers are concerned with monitoring and alarming and the higher levels with patient assessment and therapy planning. The functionality and interconnection of these layers are being determined.

  9. The Development of Philosophy and Its Fundamental Informational Turn

    Directory of Open Access Journals (Sweden)

    Kun Wu


    Full Text Available Through the rescientification of philosophy and the philosophization of science, an entirely new concept of science and philosophy as part of general human knowledge is developing. In this concept, science and philosophy become intrinsically integrated and unified, forming dynamic feedback-loops which lead to further mutual transformation and integration. This development is taking place in the face of two kinds of dogmatism: one is naturalistic dogmatism, the other the dogmatism of consciousness philosophy. These two kinds of dogmatism are an inevitable consequence of the method of segmentation of the field of existence in traditional philosophy namely: existence = matter + Spirit (mind. The development of the Science and Philosophy of Information reveals a world of information-by-itself lying between the worlds of matter and Sprit, and re-interprets the essence of the Spiritual world in the sense of prior information activities. Accordingly, we can describe the movements from matter to Spirit, and from Spirit to matter in these activities as processes, eliminating their dualistic separation, and achieve an informational turn in philosophy, the first truly fundamental one.

  11. Developing VISO: Vaccine Information Statement Ontology for patient education. (United States)

    Amith, Muhammad; Gong, Yang; Cunningham, Rachel; Boom, Julie; Tao, Cui


    To construct a comprehensive vaccine information ontology that can support personal health information applications using patient-consumer lexicon, and lead to outcomes that can improve patient education. The authors composed the Vaccine Information Statement Ontology (VISO) using the web ontology language (OWL). We started with 6 Vaccine Information Statement (VIS) documents collected from the Centers for Disease Control and Prevention (CDC) website. Important and relevant selections from the documents were recorded, and knowledge triples were derived. Based on the collection of knowledge triples, the meta-level formalization of the vaccine information domain was developed. Relevant instances and their relationships were created to represent vaccine domain knowledge. The initial iteration of the VISO was realized, based on the 6 Vaccine Information Statements and coded into OWL2 with Protégé. The ontology consisted of 132 concepts (classes and subclasses) with 33 types of relationships between the concepts. The total number of instances from classes totaled at 460, along with 429 knowledge triples in total. Semiotic-based metric scoring was applied to evaluate quality of the ontology.

  12. The Impact of Information Technology on the Design, Development, and Implementation of a Lunar Exploration Mission (United States)

    Gross, Anthony R.; Sims, Michael H.; Briggs, Geoffrey A.


    From the beginning to the present expeditions to the Moon have involved a large investment of human labor. This has been true for all aspects of the process, from the initial design of the mission, whether scientific or technological, through the development of the instruments and the spacecraft, to the flight and operational phases. In addition to the time constraints that this situation imposes, there is also a significant cost associated with the large labor costs. As a result lunar expeditions have been limited to a few robotic missions and the manned Apollo program missions of the 1970s. With the rapid rise of the new information technologies, new paradigms are emerging that promise to greatly reduce both the time and cost of such missions. With the rapidly increasing capabilities of computer hardware and software systems, as well as networks and communication systems, a new balance of work is being developed between the human and the machine system. This new balance holds the promise of greatly increased exploration capability, along with dramatically reduced design, development, and operating costs. These new information technologies, utilizing knowledge-based software and very highspeed computer systems, will provide new design and development tools, scheduling mechanisms, and vehicle and system health monitoring capabilities that have hitherto been unavailable to the mission and spacecraft designer and the system operator. This paper will utilize typical lunar missions, both robotic and crewed, as a basis to describe and illustrate how these new information system technologies could be applied to all aspects such missions. In particular, new system design tradeoff tools will be described along with technologies that will allow a very much greater degree of autonomy of exploration vehicles than has heretofore been possible. In addition, new information technologies that will significantly reduce the human operational requirements will be discussed.

  13. Development of a high-speed real-time PCR system for rapid and precise nucleotide recognition (United States)

    Terazono, Hideyuki; Takei, Hiroyuki; Hattori, Akihiro; Yasuda, Kenji


    Polymerase chain reaction (PCR) is a common method used to create copies of a specific target region of a DNA sequence and to produce large quantities of DNA. A few DNA molecules, which act as templates, are rapidly amplified by PCR into many billions of copies. PCR is a key technology in genome-based biological analysis, revolutionizing many life science fields such as medical diagnostics, food safety monitoring, and countermeasures against bioterrorism. Thus, many applications have been developed with the thermal cycling. For these PCR applications, one of the most important key factors is reduction in the data acquisition time. To reduce the acquisition time, it is necessary to decrease the temperature transition time between the high and low ends as much as possible. We have developed a novel rapid real-time PCR system based on rapid exchange of media maintained at different temperatures. This system consists of two thermal reservoirs and a reaction chamber for PCR observation. The temperature transition was achieved within 0.3 sec, and good thermal stability was achieved during thermal cycling with rapid exchange of circulating media. This system allows rigorous optimization of the temperatures required for each stage of the PCR processes. Resulting amplicons were confirmed by electrophoresis. Using the system, rapid DNA amplification was accomplished within 3.5 min, including initial heating and complete 50 PCR cycles. It clearly shows that the device could allow us faster temperature switching than the conventional conduction-based heating systems based on Peltier heating/cooling.

    Kouziokas, Georgios N.


    It is generally agreed that the governmental authorities should actively encourage the development of an efficient framework of information and communication technology initiatives so as to advance and promote sustainable development and planning strategies. This paper presents a prototype Information System for public administration which was designed to facilitate public management and decision making for sustainable development and planning. The system was developed by using several programming languages and programming tools and also a Database Management System (DBMS) for storing and managing urban data of many kinds. Furthermore, geographic information systems were incorporated into the system in order to make possible to the authorities to deal with issues of spatial nature such as spatial planning. The developed system provides a technology based management of geospatial information, environmental and crime data of urban environment aiming at improving public decision making and also at contributing to a more efficient sustainable development and planning.

  19. Assessment on the Impact of Arable Land Protection Policies in a Rapidly Developing Region

    Directory of Open Access Journals (Sweden)

    Jiadan Li


    Full Text Available To investigate the effect of arable land protection policies in China, a practical framework that integrates geographic information systems (GIS, soil quality assessment and landscape metrics analysis was employed to track and analyze arable land transformations and landscape changes in response to rampant urbanization within the Ningbo region (China from 2005 to 2013. The results showed that arable land loss and degradation have continued, despite the development of a comprehensive legal framework for arable land protection. The implementation of arable land protection policies is judged to be effective, but not entirely successful, because it guarantees the overall amount of arable land but does not consider soil quality and spatial distribution. In addition, there are distinct variations in arable land change dynamics between two temporal intervals. From 2005–2009, the transformation of arable land was diversified, with intensified conversion among arable land, built-up land, water and orchards. Moreover, many new arable land parcels were adjacent to built-up land, and are in danger of being occupied again through urban sprawl. By 2009–2013, most of the arable land was occupied by urban expansion, whereas a majority of newly increased arable land was reclaimed from coastal tideland. Although the newly increased arable land was contiguous and far from the urban area, it is of poor quality and has limited use. The permanent loss of high-quality arable land due to intensified urban sprawl may threaten sustainable development and food security on a larger scale.

  20. A Development of Rapid, Practical and Selective Process for Preparation of Z-Oximes

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Bo Ram; Sung, Gi Hyeon; Yoon, Yongjin [Gyeongsang National Univ., Jinju (Korea, Republic of); Kim, Jeumjong [Electronic and Telecommunications Research Institute, Daejeon (Korea, Republic of)


    Oximes are important functional groups in organic chemistry due to their synthetic utility as protecting groups for carbonyl groups and their ability to form other functionalities, and their biological activity. Oximes are commonly prepared by condensing aldehydes and ketones with hydroxylamines. These reactions do not always go to completion and reaction times can be long, and therefore there has been interest in more convenient and efficient methods. To avoid the typical disadvantage, conversion of aldehydes and ketones to the corresponding oximes was accomplished by using various catalysts such as organic acid/bases, AcONa, alumina, TiO{sub 2}/SO{sub 4} silica gel, Oxone, NaOH, basic ionic liquid 1-butyl-3-methylimidazolium hydroxide, polyoxometalates, Na{sub 2}SO{sub 4}, and CuSO{sub 4}/K{sub 2}CO{sub 3} under the solvent, the solvent-free or the microwave conditions. These are one and more drowbacks such as long reaction time, use of catalysts, inconvenients due to solid-sate reaction, low yields and limitaion of some carbonyl compounds. On the other hand, H. Sharghi, et al.,14 reported the catalysis of the stereoselectivity of CuSO{sub 4} and K{sub 2}CO{sub 3} in the oximation of aldehydes and ketones under solvent-free conditions. Although this method show high selectivity, it is inconvenient for the large scale experiments and the industrial process due to the solvent-free condition. Therefore, we attempted to develop a more convenient and efficient solution method. According to the literatures, treatment of potassium carbonate with methanol generates slightly the potassium methoxide, which may be useful for forming the free NH{sub 2}OH from its salts. We describe the oximation of aldehyde and ketone using NH{sub 2}OH·HCl/K{sub 2}CO{sub 3} in methanol solvent. We selected oximation of acetophenone (1a) with hydroxylamine hydrochloride as a model and its behavior was investigated in seven solvents involving methanol (Table 1). As shown in the Entry 2 in

  4. Rapid Facial Reactions to Emotional Facial Expressions in Typically Developing Children and Children with Autism Spectrum Disorder (United States)

    Beall, Paula M.; Moody, Eric J.; McIntosh, Daniel N.; Hepburn, Susan L.; Reed, Catherine L.


    Typical adults mimic facial expressions within 1000ms, but adults with autism spectrum disorder (ASD) do not. These rapid facial reactions (RFRs) are associated with the development of social-emotional abilities. Such interpersonal matching may be caused by motor mirroring or emotional responses.

  8. Spatial–Temporal Patterns and Driving Factors of Rapid Urban Land Development in Provincial China: A Case Study of Jiangsu

    Directory of Open Access Journals (Sweden)

    Qingke Yang


    Full Text Available Since its economic reform and opening-up, China has undergone unprecedented urbanization, where massive areas of rural land have been converted into urban use. Urban land development plays an important role in dynamic urban economic development. This study aims to contribute to the understanding of urban land development and its mechanisms in China. We conceptualized the mechanism of urban land development from multiple perspectives based on a case study in Jiangsu Province. We employed the methods of global and local spatial auto-correlation detection and spatial lag model to analyze the provincial land use conveyance and survey data from 2004 to 2008 and 2009 to 2012 to understand the dynamics of urban land development. The results show that urban land development varies significantly across different time periods, spatial scales, and regions in Jiangsu. Higher absolute urban land development mainly occurred in Sunan, expanding to Subei and Suzhong, while faster development occurred mainly in Subei, where the initial bases were lower but had strong economic growth potential. The regression analysis shows that market activities and administrative levels had played a more critical role in driving urban land development, which suggests that rapid urban land development has institutional and market foundations. Urban land development was not only a consequence of economic development but also a strategy of local governments to stimulate and govern the urban economy. This study enriches the literature on urban dynamics by providing an institutional understanding of rapid urban land development in a transitional economy.

  13. From Management Information Systems to Business Intelligence: The Development of Management Information Needs

    Directory of Open Access Journals (Sweden)

    Gėlytė Kazakevičienė


    Full Text Available Despite the advances in IT, information systems intended for management informing did not uniformly fulfil the increased expectations of users; this can be said mostly about complex information needs. Although some of the technologies for supporting complicated insights, like management decision support systems and technologies, experienced reduction in interest both from researchers and practitioners, this did not reduce the importance of well-supported business informing and decision making. Being attributed to the group of intelligent systems and technologies, decision support (DS technologies have been largely supplemented by business intelligence (BI technologies. Both types of technologies are supported by respective information technologies, which often appear to be quite closely related. The objective of this paper is to define relations between simple and complex informing intended to satisfy different sets of needs and provided by different sets of support tools. The paper attempts to put together decision support and business intelligence technologies, based on common goals of sense-making and use of advanced analytical tools. A model of two interconnected cycles has been developed to relate the activities of decision support and business intelligence. Empirical data from earlier research is used to direct possible further insights into this area.

  14. Development of a novel multiplex PCR assay for rapid detection of virulence associated genes of Pasteurella multocida from pigs. (United States)

    Rajkhowa, S


    As the pathogenicity of Pasteurella multocida is associated with various virulence factors (VFs), the aim of the study was to develop a novel multiplex PCR (m-PCR) assay for the rapid detection of important virulence associated genes (VAGs) of P. multocida isolates from pigs. The target recognized VFs used in the study were diverse adhesins (ptfA and pfhA), toxins (toxA), siderophores (tonB and hgbA), sialidases (nanB, nanH) and outer membrane proteins (ompA, ompH, oma87 and plpB). The primers for the genes encoding these VFs were designed by primer3 software ( using gene sequences available in Genbank. The detection limit of the developed assay was 10(2)  CFU ml(-1) . The m-PCR did not produce any nonspecific amplification products when tested against Bordetella bronchiseptica which also commonly infects pigs. We applied m-PCR to the field samples, and the results obtained were the same as the single PCR results. The developed assay would be very useful for veterinary diagnostic laboratories and for others interested in the rapid virulence profiling of porcine P. multocida isolates circulating in the piggeries. The study reports the development and evaluation of a novel multiplex PCR assay for the rapid detection of 11 important VAGs of Pasteurella multocida isolates from pigs. Rapid and simultaneous detection of recognized VFs of the organism are essential to know the virulo-types of P. multocida isolates circulating in the piggeries. The developed novel assay will be very useful for the rapid detection of VAGs of P. multocida isolates from pigs. © 2015 The Society for Applied Microbiology.

  15. Section 508 Electronic Information Accessibility Requirements for Software Development (United States)

    Ellis, Rebecca


    Section 508 Subpart B 1194.21 outlines requirements for operating system and software development in order to create a product that is accessible to users with various disabilities. This portion of Section 508 contains a variety of standards to enable those using assistive technology and with visual, hearing, cognitive and motor difficulties to access all information provided in software. The focus on requirements was limited to the Microsoft Windows® operating system as it is the predominant operating system used at this center. Compliance with this portion of the requirements can be obtained by integrating the requirements into the software development cycle early and by remediating issues in legacy software if possible. There are certain circumstances with software that may arise necessitating an exemption from these requirements, such as design or engineering software using dynamically changing graphics or numbers to convey information. These exceptions can be discussed with the Section 508 Coordinator and another method of accommodation used.

  18. Prevalence of organic and inorganic contaminants within a rapidly developing catchment (United States)

    Njumbe, E. S.; Curtis, C. D.; Cooke, D. A.; Polya, D. A.; Wogelius, R. A.; Hughes, C.


    Industrialization rates in many developing countries typically outpace investment in water supply, sewage treatment and other waste water facilities. This is futher compounded by the absence of stringent land-use and waste disposal policies. The consequence of this has been contamination of land, surface water, and groundwater in such areas. Efforts to control and remediate these types of systems will rely on a thorough understanding of contaminant levels and mobility. Reliable data, however, is usually not available. Therefore this study was designed to acquire baseline data from a representative developing urban area in tropical west Africa. 43 water and 20 sediment/soil samples from streams, hand-dug wells, springs and deep boreholes within the city and surrounding areas of Douala in Cameroon were characterised. Analyses were aimed at obtaining information on the type and quantity of organic and inorganic contaminants present, and linking them to specific point and non-point sources. Results from gas chromatography (GC/FID) and gas chromatography/mass spectrometry analyses of total organic extracts (TOE) of water samples have revealed the presence of a wide range of organic compounds including phenols, polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), phthalates, acids and aliphatic derivatives. Concentrations as high as 500 ng ml-1 were detected. These high levels of non-polar compounds measured in drinking water represent a clear health problem. Heavy metal concentrations in bulk alluvial sands and loamy soil have been determined by microwave assisted nitric acid digestion. Concentration ranges (in ppm of dry weight) for the important metals were: Cr, 3.2-84.2 ; Ni, 0.2-57.4 ; Zn, 2.1-92 ; Pb, 0.3-33 ; As, 0.081-9.4 ; Cu, 0.61-17.4 ; and Cd, 0-3.1. Point sources have been identified for several of the organic and inorganic compounds and this spatial information will be integrated with the chemical data to present an overview of
