    We synthesized manganese oxides supported on gold nanoparticles (diameter gold nanoparticles under hydrothermal conditions. In this green method Mn oxide is deposited on the gold nanoparticles. The compounds were characterized by scanning electron microscopy, energy-dispersive spectrometry, high-resolution transmission electron microscopy, X-ray diffraction, UV-Vis spectroscopy, Fourier transform infrared spectroscopy, and atomic absorption spectroscopy. In the next step, the water-oxidizing activities of these compounds in the presence of cerium(IV) ammonium nitrate as a non-oxo transfer oxidant were studied. The results show that these compounds are good catalysts toward water oxidation with a turnover frequency of 1.0 ± 0.1 (mmol O2/(mol Mn·s)). A comparison with other previously reported Mn oxides and important factors influencing the water-oxidizing activities of Mn oxides is also discussed.

    It would be difficult to condense current issues in nuclear reactor regulation to just a few minutes. So, let me start off by saying that I have not tried to give a comprehensive listing of issues that are currently facing the reactor program, but rather to select those that I thought were relevant as they relate to research activities. Use of probabilistic risk assessment in regulatory decisions; materials aging issues concerning steam generators and reactor vessels; high burnup fuels; accident management; and digital instrumentation and control, are just a sampling of the important issues that I want to talk about.

    Dibromochloropropane, DBCP, has had a seminal role in our current understanding of how to prevent chemical risks to health. Early toxicological studies showed its special impact on the testes, and detection of its mutagenic potency was soon followed by demonstration of its carcinogenicity to animals. Its commercial use as a useful nematocide ignored, at first, these warnings from the laboratory. When production workers, first in California and then in Israel, found they were sterile as a result of their exposure, this was convincing evidence that prevention had failed. The evidence, azospermia, oligospermia, and gonadotrophin response to testicular damage, were found first in production workers. In agricultural applicators in California who used the material, decreased sperm count and increased gonadotrophin levels were found. While production in California, Texas, and Israel was halted, studies continued and so, it seems, did use. Our first Israeli study was of workers on banana crops, and we found convincing evidence of increased spontaneous abortion in their family histories. Follow-up studies among production workers in Israel showed that some recovered testicular function, but among their offspring, otherwise in good health, there was a predominance of females. Those who did not recover from azospermia were those with high levels of follicle stimulating hormone. However data for production workers did not show increased spontaneous abortion. Nor have any studies so far shown increased birth defects or increased infant mortality. Unfavorable reproductive outcomes can be due to other agents, as shown by sprayers in Dutch orchards having hypofecundity (increased interpregnancy period) and sex ratio changes; but the agents responsible have not yet been identified. These experiences have lead to the general acceptance of some implications: (1) Paternal exposures can lead to a variety of unfavorable effects on reproductive outcome, including infertility, spontaneous

    Saffron (Crocus savitus) is a Middle-Eastern herb with strong antioxidant properties. Its major constituents, safranal, crocin, and crocetin, are also antioxidants and bear structural similarities to other well-known natural antixodant substances, such as zeaxanthin. Given the role of oxidative stress in many diseases, considerable interest has been shown into the potential role of saffron supplementation as a treatment for a range of diseases. In vitro and animal studies have provided evidence that saffron and its constituents may be potent therapies for a range of pathologies, including Alzheimer's disease, age-related macular degeneration (AMD) and cardiac ischemia. Whether these findings translate into clinical efficacy, however, has as of yet been incompletely assessed. This makes assessing the role of saffron supplementation in these diseases difficult. Here, we review the current human clinical evidence supporting saffron supplementation as a treatment for a range of pathologies and the underlying science supporting its use.

    Full Text Available Aromatase inhibitor "letrozole" was first introduced as a potential ovulation induction (OI drug almost a decade back. Large number of studies has been published using letrozole for OI: In polycystic ovary syndrome (PCOS women, clomiphene citrate (CC resistant women, for intrauterine insemination and also in various protocols of mild stimulation for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI. Letrozole appears to be a good option, with its oral route of administration, cost, shorter half-life and negligible side effects. However, the verdict on efficacy and safety of letrozole is still uncertain. This review explores the current scientific data supporting letrozole for OI.

    With more than 100 orthopaedic, sports medicine, or hand surgery journals indexed in MEDLINE, it is no longer possible to keep abreast of developments in orthopaedic surgery by reading a few journals each month. Electronic resources are easier to search and more current than most print sources. We provide a practical approach to finding useful information to guide orthopaedic practice. We focus first on where to find the information by providing details about many useful databases and web links. Sources for identifying guidelines, systematic reviews, and randomized controlled trials are identified. The second section discusses how to find the information, from the first stage of formulating a question and identifying the concepts of interest, through to writing a simple strategy. Sources for additional self-directed learning are provided.

    2008-01-01

    This review examines the current empirical research and literature on peer assistance programs, peer support, and peer-facilitated interventions for police officers. A literature search was conducted to identify studies on police, peer support, and peer assistance programs. Studies were examined in terms of the following criteria: description of data collection methods, findings, study limitations, implications for police, workplace assistance, and peer support. Articles on peer support in the aftermath of the September 11, 2001, World Trade Center rescue and recovery efforts were also reviewed. The research studies reviewed in this article do not evaluate peer program effectiveness from the perspective of those officers receiving peer services. To better serve this invaluable population, efforts must be made to incorporate their views. Information is also needed on the effectiveness of peer assistance programs and peer-driven crisis intervention models. Finally, research is needed that specifically examines the effectiveness of programs that utilize trained peers in partnership with professional mental health practitioners.

    Full Text Available Abstract The development of acute myeloid leukemia (AML is a multistep process that requires at least two genetic abnormalities for the development of the disease. The identification of genetic mutations in AML has greatly advanced our understanding of leukemogenesis. Recently, the use of novel technologies, such as massively parallel DNA sequencing or high-resolution single-nucleotide polymorphism arrays, has allowed the identification of several novel recurrent gene mutations in AML. The aim of this review is to summarize the current findings for the identification of these gene mutations (Dnmt, TET2, IDH1/2, NPM1, ASXL1, etc., most of which are frequently found in cytogenetically normal AML. The cooperative interactions of these molecular aberrations and their interactions with class I/II mutations are presented. The prognostic and predictive significances of these aberrations are also reviewed.

  12. Electron currents supporting the near-Earth magnetotail during current sheet thinning

    Formation of intense, thin current sheets (i.e., current sheet thinning) is a critical process for magnetospheric substorms, but the kinetic physics of this process remains poorly understood. Using a triangular configuration of the three Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft at the end of 2015 we investigate field-aligned and transverse currents in the magnetotail current sheet around 12 Earth radii downtail. Combining the curlometer technique with direct measurements of ion and electron velocities, we demonstrate that intense, thin current sheets supported by strong electron currents form in this region. Electron field-aligned currents maximize near the neutral plane Bx˜0, attaining magnitudes of ˜20 nA/m2. Carried by hot (>1 keV) electrons, they generate strong magnetic shear, which contributes up to 20% of the vertical (along the normal direction to the equatorial plane) pressure balance. Electron transverse currents, on the other hand, are carried by the curvature drift of anisotropic, colder (<1 keV) electrons and gradually increase during the current sheet thinning. In the events under consideration the thinning process was abruptly terminated by earthward reconnection fronts which have been previously associated with tail reconnection further downtail. It is likely that the thin current sheet properties described herein are similar to conditions further downtail and are linked to the loss of stability and onset of reconnection there. Our findings are likely applicable to thin current sheets in other geophysical and astrophysical settings.

  13. Do current European policies support soil multifunctionality?

    Science.gov (United States)

    Helming, Katharina; Glaesner, Nadia; de Vries, Wim

    2017-04-01

    Soils are multifunctional. Maximising one function, e.g. production of biomass, is often at the costs of the other functions, e.g. water purification, carbon sequestration, nutrient recycling, habitat provision. Sustainable soil management actually means the minimization of trade-offs between multiple soil functions. While Europe does not have a policy that explicitly focuses on soil functions, a number of policies exist in the agricultural, environmental and climate domains that may affect soil functions, in particular food production, water purification, climate change mitigation, biodiversity conservation. The objective of this study was to identify gaps and overlaps in existing EU legislation that is related to soil functions. We conducted a cross-policy analysis of 19 legislative policies at European level. Results revealed two key findings: (i) soil functions are addressed in existing legislation but with the approach to their conservation rather than their improvement. (ii) Different legislations addressed isolated soil functions but there is no policy in place that actually addressed the soil multifunctionality, which is the integrated balancing of the multitude of functions. Because soil degradation is ongoing in Europe, it raises the question whether existing legislation is sufficient for maintaining soil resources and achieving sustainable soil management. Addressing soil functions individually in various directives fails to account for the multifunctionality of soil. Here, research has a role to play to better reveal the interacting processes between soil functions and their sensitivity to soil management decisions and to translate such understanding into policy recommendation. We conclude the presentation with some insights into a research approach that integrates the soil systems into the socio-economic systems to improve the understanding of soil management pressures, soil functional reactions and their impacts on societal value systems, including

    2015-01-01

    This study investigates how faculty, student, and course features are linked to student outcomes in Learning Assistant (LA) supported courses. Over 4,500 students and 17 instructors from 13 LA Alliance member institutions participated in the study. Each participating student completed an online concept inventory at the start (pre) and end (post) of their term. The physics concept inventories included Force and Motion Concept Evaluation (FMCE) and the Brief Electricity and Magnetism Assessment (BEMA). Concepts inventories from the fields of biology and chemistry were also included. Our analyses utilize hierarchical linear models that nest student level data (e.g. pre/post scores and gender) within course level data (e.g. discipline and course enrollment) to build models that examine student outcomes across institutions and disciplines. We report findings on the connections between students' outcomes and their gender, race, and time spent working with LAs as well as instructors' experiences with LAs.

    A central issue in education is how to support the spatial thinking involved in learning science, technology, engineering, and mathematics (STEM). We investigated whether and how the cognitive process of analogical comparison supports learning of a basic spatial concept in geoscience, fault. Because of the high variability in the appearance of faults, it may be difficult for students to learn the category-relevant spatial structure. There is abundant evidence that comparing analogous examples can help students gain insight into important category-defining features (Gentner in Cogn Sci 34(5):752-775, 2010). Further, comparing high-similarity pairs can be especially effective at revealing key differences (Sagi et al. 2012). Across three experiments, we tested whether comparison of visually similar contrasting examples would help students learn the fault concept. Our main findings were that participants performed better at identifying faults when they (1) compared contrasting (fault/no fault) cases versus viewing each case separately (Experiment 1), (2) compared similar as opposed to dissimilar contrasting cases early in learning (Experiment 2), and (3) viewed a contrasting pair of schematic block diagrams as opposed to a single block diagram of a fault as part of an instructional text (Experiment 3). These results suggest that comparison of visually similar contrasting cases helped distinguish category-relevant from category-irrelevant features for participants. When such comparisons occurred early in learning, participants were more likely to form an accurate conceptual representation. Thus, analogical comparison of images may provide one powerful way to enhance spatial learning in geoscience and other STEM disciplines.

  17. Desmoplastic Small Round Cell Tumor: Current Management and Recent Findings

    Directory of Open Access Journals (Sweden)

    Armelle Dufresne

    2012-01-01

    Full Text Available Desmoplastic small round cell tumor (DSRCT is a rare and highly aggressive mesenchymal tumor that develops in the abdominal cavity of young men adults. Patients typically present with symptoms of abdominal sarcomatosis. Diagnosis is based on histological analysis of biopsies which typically show small round blue cells in nests separated by an abundant desmoplastic stroma. DSRCT is associated with a unique chromosomal translocation t(11:22 (p 13; q 12 that involves the EWSR1 and WT1 genes. The prognosis is particularly poor; median survival ranges from 17 to 25 months, largely due to the presentation of the majority of patients with metastatic disease. Management of DSRCT remains challenging and current schemes lack a significant cure rate despite the use of aggressive treatments such as polychemotherapy, debulking surgery and whole abdominal radiation. Several methods are being evaluated to improve survival: addition of chemotherapy and targeted therapies to standard neoadjuvant protocol, completion of surgical resection with HIPEC, postoperative IMRT, treatment of hepatic metastases with [90Y]Yttrium microsphere liver embolization.

  18. Neural mechanisms of rhythm perception: current findings and future perspectives.

    2012-10-01

    Perception of temporal patterns is fundamental to normal hearing, speech, motor control, and music. Certain types of pattern understanding are unique to humans, such as musical rhythm. Although human responses to musical rhythm are universal, there is much we do not understand about how rhythm is processed in the brain. Here, I consider findings from research into basic timing mechanisms and models through to the neuroscience of rhythm and meter. A network of neural areas, including motor regions, is regularly implicated in basic timing as well as processing of musical rhythm. However, fractionating the specific roles of individual areas in this network has remained a challenge. Distinctions in activity patterns appear between "automatic" and "cognitively controlled" timing processes, but the perception of musical rhythm requires features of both automatic and controlled processes. In addition, many experimental manipulations rely on participants directing their attention toward or away from certain stimulus features, and measuring corresponding differences in neural activity. Many temporal features, however, are implicitly processed whether attended to or not, making it difficult to create controlled baseline conditions for experimental comparisons. The variety of stimuli, paradigms, and definitions can further complicate comparisons across domains or methodologies. Despite these challenges, the high level of interest and multitude of methodological approaches from different cognitive domains (including music, language, and motor learning) have yielded new insights and hold promise for future progress.

    Human genome and exome sequencing are powerful research tools that can generate secondary findings beyond the scope of the research. Most secondary genomic findings are of low importance, but some (for a current estimate of 1%–3% of individuals) confer high risk of a serious disease that could be mitigated by timely medical intervention. The impact and scope of secondary findings in genome and exome sequencing will only increase in the future. There is considerable agreement that high-impact findings should be returned to participants, but many researchers performing genomic research studies do not have the background, skills, or resources to identify, verify, interpret, and return such variants. Here, we introduce a proposal for the formation of a secondary-genomic-findings service (SGFS) that would support researchers by enabling the return of clinically actionable sequencing results to research participants in a standardized manner. We describe a proposed structure for such a centralized service and evaluate the advantages and challenges of the approach. We suggest that such a service would be of greater benefit to all parties involved than present practice, which is highly variable. We encourage research centers to consider the adoption of a centralized SGFS. PMID:26942283

    Full Text Available The research reported in this dissertation contains three complementary and overlapping parts:One, “findings”: It assesses the factors of urban morphology that contribute to increased rates of greenhouse gas emissions per capita, and the ways they interact. It finds a significant but underrepresented set of factors, distinct from but relating the factors at the individual building scale and the scale of regional transportation systems.Two, “strategies”: It assesses the methodologies by which such findings might be put to use in identifying and achieving reductions through changes in urban design, and proposes new strategies to do so using innovative forms of design decision support tools.Three, “design decision support tools”: It then proposes a specific new technology, namely a new class of open-source scenario-modelling tool, embodied in new prototype software. The tool utilizes a new kind of “federated” web-based wiki technology incorporating design pattern languages, which was developed in collaboration with the software engineer and wiki inventor Ward Cunningham.As part of this research, it has been necessary to examine fundamental methodological questions, and to account for limitations of current data as well as current significant gaps in research. In the process, this research has made a modest contribution to the state of knowledge about additional research needed.For me, this work has also highlighted the need for urgent and effective reforms to current “business as usual” practices. The need is all the more urgent given unprecedented rates of urbanisation – much of it sprawling and resource-inefficient – taking place in many parts of the world today.

    Full Text Available Heart failure is a major public health problem and its management requires a significant amount of health care resources. Even with administration of the best available medical treatment, the mortality associated with the disease remains high. As therapeutical strategies for heart failure have been refined, the number of patients suffering from the disease has expanded dramatically. Although heart transplantation still represents the gold standard therapeutical approach, the implantation of mechanical circulatory support devices (MCSDs evolved to a well-established management for this disease. The limited applicability of heart transplantation caused by a shortage of donor organs and the concurrent expand of the patient population with end-stage heart failure led to a considerable utilization of MCSDs. This paper outlines the current status of mechanical circulatory support.

    2010-11-30

    The success of the first Green Revolution in the form of abundant food supplies and low prices over the past two decades has diverted the world's attention from agriculture to other pressing issues. This has resulted in lower support for the agricultural research work primarily undertaken by the 15 research centers of the Consultative Group on International Agricultural Research (CGIAR). The total support in real dollars for most of the last three decades has been more or less flat although the number of centers increased from 4 to 15. However, since 2000, the funding situation has improved for the CGIAR centers, with almost all the increase coming from grants earmarked for specific research projects. Even for some centers such as the International Rice Research Institute (IRRI), the downward trend continued as late as 2006 with the budget in real dollars reaching the 1978 level of support. The recent food crisis has renewed the call for a second Green Revolution by revitalizing yield growth to feed the world in the face of growing population and a shrinking land base for agricultural use. The slowdown in yield growth because of decades of neglect in agricultural research and infrastructure development has been identified as the underlying reason for the recent food crisis. For the second Green Revolution to be successful, the CGIAR centers will have to play a complex role by expanding productivity in a sustainable manner with fewer resources. Thus, it is crucial to examine the current structure of support for the CGIAR centers and identify the challenges ahead in terms of source and end use of funds for the success of the second Green Revolution. The objective of this paper is to provide a historical perspective on the support to the CGIAR centers and to examine the current status of funding, in particular, the role of project-specific grants in rebuilding capacity of these centers. The paper will also discuss the nature of the support (unrestricted vs. project

    Full Text Available Objectives: Electronic cigarette (e-cigarette use is increasing in the U.S. Although marketed as a safer alternative for cigarettes, initial evidence suggests that e-cigarettes may pose a secondhand exposure risk. The current study explored the prevalence and correlates of support for e-cigarette bans. Methods: A sample of 265 current/former smokers completed a cross-sectional telephone survey from June–September 2014; 45% Black, 31% White, 21% Hispanic. Items assessed support for home and workplace bans for cigarettes and e-cigarettes and associated risk perceptions. Results: Most participants were aware of e-cigarettes (99%. Results demonstrated less support for complete e-cigarette bans in homes and workplaces compared to cigarettes. Support for complete e-cigarette bans was strongest among older, higher income, married respondents, and former smokers. Complete e-cigarette bans were most strongly endorsed when perceptions of addictiveness and health risks were high. While both e-cigarette lifetime and never-users strongly supported cigarette smoking bans, endorsement for e-cigarette bans varied by lifetime use and intentions to use e-cigarettes. Conclusions: Support for indoor e-cigarette bans is relatively low among individuals with a smoking history. Support for e-cigarette bans may change as evidence regarding their use emerges. These findings have implications for public health policy.

    Word finding difficulties frequently found in learners with language learning difficulties (Casby, 1992) are an integral part of Speech-Language Therapists' management role when working with learning disabled children. This study investigated current management for word finding difficulties by 70 Speech-Language Therapists in South African remedial schools. A descriptive survey design using a quantitative and qualitative approach was used. A questionnaire and follow-up focus group discussion were used to collect data. Results highlighted the use of the Renfrew Word Finding Scale (Renfrew, 1972, 1995) as the most frequently used formal assessment tool. Language sample analysis and discourse analysis were the most frequently used informal assessment procedures. Formal intervention programmes were generally not used. Phonetic, phonemic or phonological cueing were the most frequently used therapeutic strategies. The authors note strengths and raise concerns about current management for word finding difficulties in South African remedial schools, particularly in terms of bilingualism. Opportunities are highlighted regarding the development of assessment and intervention measures relevant to the diverse learning disabled population in South Africa.

    Personalized medicine, the ability to tailor diagnostic and treatment decisions for individual patients, is seen as the evolution of modern medicine. We characterize here the informatics resources available today or envisioned in the near future that can support clinical interpretation of genomic test results. We assume a clinical sequencing scenario (germline whole-exome sequencing) in which a clinical specialist, such as an endocrinologist, needs to tailor patient management decisions within his or her specialty (targeted findings) but relies on a genetic counselor to interpret off-target incidental findings. We characterize the genomic input data and list various types of knowledge bases that provide genomic knowledge for generating clinical decision support. We highlight the need for patient-level databases with detailed lifelong phenotype content in addition to genotype data and provide a list of recommendations for personalized medicine knowledge bases and databases. We conclude that no single knowledge base can currently support all aspects of personalized recommendations and that consolidation of several current resources into larger, more dynamic and collaborative knowledge bases may offer a future path forward.

  18. Personal view: current role of artificial liver support devices.

    O'Grady, J

    2006-06-01

    Enthusiasm for liver support devices, particularly cell-based biological systems and albumin dialysis, increased over the last decade and there has been considerable clinical activity both within and without the construct of clinical trials. Most data have been generated on patients with acute liver failure or in patients with decompensation of chronic liver disease, often referred to as acute-on-chronic liver failure. In acute liver failure liver, liver support devices are more realistically being used as a 'bridge' to liver transplantation rather than to transplant-free survival. In acute-on-chronic liver failure the clinical objective of attaining clinical stability with treatment appears more achievable. The so-called bioartificial liver device, based on porcine hepatocytes, is the most extensively evaluated biological device. A sizeable clinical trial failed to demonstrate efficacy, but secondary analyses suggest it would be unwise to assume futility had been established with this device. Molecular adsorbent recirculating system leads the way in the non-biological category in terms of the number of patients treated, but data from large clinical trials are not yet available. One of the strongest conclusions of this review is that the amount of high-quality data available on liver support devices dramatically understates the effort and money that have been expended in their assessment. It is very clear that randomized controlled trials are mandatory to establish clinical efficacy, but it is less clear how the ideal trial should be constructed.

  19. Current concepts on hemodynamic support and therapy in septic shock

    Directory of Open Access Journals (Sweden)

    Leonardo Lima Rocha

    2015-10-01

    Full Text Available ABSTRACTSevere sepsis and septic shock represent a major healthcare challenge. Much of the improvement in mortality associated with septic shock is related to early recognition combined with timely fluid resuscitation and adequate antibiotics administration. The main goals of septic shock resuscitation include intravascular replenishment, maintenance of adequate perfusion pressure and oxygen delivery to tissues. To achieve those goals, fluid responsiveness evaluation and complementary interventions - i.e. vasopressors, inotropes and blood transfusion - may be necessary. This article is a literature review of the available evidence on the initial hemodynamic support of the septic shock patients presenting to the emergency room or to the intensive care unit and the main interventions available to reach those targets, focusing on fluid and vasopressor therapy, blood transfusion and inotrope administration.

    Messer, E

    1997-06-01

    This work offers an anthropological analysis of intra-household processes underlying gender- and age-specific differences in individual nutritional and health care allocations and outcomes in particular cultures. Based on recent ethnographic studies in India, Nepal, Madagascar, Mexico, and Peru, correspondences are analyzed between local cultural ("emic") and scientist-policy maker practitioner ("etic") understandings of nutrition, health, and human development, and the relative "values" of females, males, and children of different ages. The data and analyses clarify specific epidemiological and demographic findings on age and gender bias in nutrition and health and highlight the multiple cultural, economic, and biological factors that contribute to gender- or age-based discrimination or neglect. Recent advances in nutrition policy have argued for a broader concept of nutritional security, one that incorporates both food quantity and quality, and of nutrition as "food, health and care" (International Conference on Nutrition, World Declaration and Plan of Action for Nutrition, FAO/WHO, Rome, 1992). These ethnographic findings; lend strong support for such broader nutrition concepts and associated nutrition policies. The studies also suggest ways in which anthropological questions, methods, and data and community-based research can help predict or identify the nutritionally vulnerable within households and help other social and medical scientists design more effective interventions.

  1. Alterations of tendons in diabetes mellitus: what are the current findings?

    As a connective tissue, tendon connects the muscle and bone, and plays the key role in the locomotor system. Some previous studies have shown the pathological alternations in diabetic tendons, which might result in the structural and functional changes, and even accelerate the process of diabetic foot. In this review, we examined the current findings of the diabetic tendons in the form of various aspects, and summarized the clinical presentation, imaging, biomechanical, histopathological, cellular and molecular abnormalities in the diabetic tendons. The progress of diabetic tendon damage is complicated and the main hypotheses include the excessive accumulation of AGEs, the altered inflammatory response, neovascularization and insensitive neuropathy. However, the cellular and molecular mechanisms of these alterations are still ambiguous. Tendon stem/progenitor cells (TSPCs) have been discovered to play important roles in both tendon physiology and tendon pathology. Recently, we identified TSPCs from patellar tendons in our well-established diabetic rat model and found impaired tenogenic differentiation potential of these cells. We proposed a new hypothesis that the impaired cell functions of diabetic TSPCs might be the underlying cellular and molecular mechanism of the diabetic tendon alternations. These findings should be helpful to establish a better therapeutic strategy for diabetic tendon repair and regeneration.

  2. Decision Support for Route Search and Optimum Finding in Transport Networks under Uncertainty

    2015-02-01

    Full Text Available The aim of this paper is to find solution for route planning in road network for a user, and to find the equilibrium in the path optimization problem, where the roads have uncertain attributes. The concept is based on the Dempster-Shafer theory and Dijkstra's algorithm, which help to model the uncertainty and to find the best route, respectively. Based on uncertain influencing factors an interval of travel time (so called cost interval of each road can be calculated. An algorithm has been outlined for determining the best route comparing the intervals and using decision rules depending on the user's attitude. Priorities can be defined among the rules, and the constructed rule based mechanism for users’ demands is great contribution of this paper. The first task is discussed in more general in this paper, i.e. instead of travel time a general cost is investigated for any kind of network. At the solution of the second task, where the goal is to find equilibrium in transport network at case of uncertain situation, the result of the first task is used. Simulation tool has been used to find the equilibrium, which gives only approximate solution, but this is sufficient and appropriate solution for large networks. Furthermore this is built in a decision support system, which is another contribution of this work. At the end of the paper the implementation of the theoretical concept is presented with a test bed of a town presenting effects of different uncertain influencing factors for the roads.

    2013-02-01

    Full Text Available The clinical diagnosis of Creutzfeldt-Jakob disease (CJD is largely based on the 1998 World Health Organization diagnostic criteria. Unfortunately, rigid compliance with these criteria may result in failure to recognize sporadic CJD (sCJD, especially early in its course when focal findings predominate and traditional red flags are not yet present. A 61-year-old man presented with a 3-week history of epilepsia partialis continua (jerking of the left upper extremity and a 2-week history of forgetfulness and left hemiparesis; left hemisensory neglect was also detected on admission. Repeated brain magnetic resonance imaging (MRI showed areas of restricted diffusion in the cerebral cortex, initially on the right but later spreading to the left. Electroencephalography (EEG on hospital days 7, 10, and 14 showed right-sided periodic lateralized epileptiform discharges. On day 20, the EEG showed periodic sharp wave complexes leading to a diagnosis of probable sCJD and subsequently to definite sCJD with brain biopsy. Neurological decline was relatively fast with generalized myoclonus and akinetic mutism developing within 7 weeks from the onset of illness. CJD was not immediately recognized because of the patient’s focal/lateralized manifestations. Focal/lateralized clinical, EEG, and MRI findings are not uncommon in sCJD and EEG/MRI results may not be diagnostic in the early stages of sCJD. Familiarity with these caveats and with the most current criteria for diagnosing probable sCJD (University of California San Francisco 2007, MRI-CJD Consortium 2009 will enhance the ability to recognize sCJD and implement early safety measures.

    Design of rib support systems in U.S. coal mines is based primarily on local practices and experience. A better understanding of current rib support practices in U.S. coal mines is crucial for developing a sound engineering rib support design tool. The objective of this paper is to analyze the current practices of rib control in U.S. coal mines. Twenty underground coal mines were studied representing various coal basins, coal seams, geology, loading conditions, and rib control strategies. The key findings are: (1) any rib design guideline or tool should take into account external rib support as well as internal bolting; (2) rib bolts on their own cannot contain rib spall, especially in soft ribs subjected to significant load-external rib control devices such as mesh are required in such cases to contain rib sloughing; (3) the majority of the studied mines follow the overburden depth and entry height thresholds recommended by the Program Information Bulletin 11-29 issued by the Mine Safety and Health Administration; (4) potential rib instability occurred when certain geological features prevailed-these include draw slate and/or bone coal near the rib/roof line, claystone partings, and soft coal bench overlain by rock strata; (5) 47% of the studied rib spall was classified as blocky-this could indicate a high potential of rib hazards; and (6) rib injury rates of the studied mines for the last three years emphasize the need for more rib control management for mines operating at overburden depths between 152.4 m and 304.8 m.

  7. Current Findings and Mechanisms of Action of Disulfiram in the Treatment of Alcohol Dependence.

    2016-07-01

    As an alcohol-aversive agent, disulfiram occupies an exceptional position in the pharmacological relapse prevention of alcohol dependence. In contrast to anti-craving drugs, disulfiram does not modulate neurobiological mechanisms of addiction, but rather works by producing an aversive reaction when combined with alcohol. Therapeutic and adverse effects are therefore closely related: On the one hand, the aversiveness of the disulfiram ethanol reaction has the potential to support abstinence in a subgroup of alcohol-dependent patients, while on the other hand it becomes a health threat if the patient fails to maintain complete abstinence. The exceptional position of disulfiram is also related to the role that expectations play in the mediation of therapeutic effects. These are not determined by the pharmacological effects or the actual occurrence of a disulfiram-ethanol reaction, but are attributable to patient awareness that the drug was consumed and the corresponding anticipation of an aversive reaction if combined with alcohol. This is in line with the findings of a recent meta-analysis that only showed significant effects for disulfiram in open-label trials. The authors of the meta-analysis conclude that due to expectations induced in both the treatment and placebo groups, blinded studies are incapable of distinguishing a difference between groups. The mediation of therapeutic effects through expectation has a number of consequences for clinical practice and future research on disulfiram.

    Information and communication technology holds promise in terms of providing support and reducing isolation among older adults. We evaluated the impact of a specially designed computer system for older adults, the Personal Reminder Information and Social Management (PRISM) system. The trial was a multisite randomized field trial conducted at 3 sites. PRISM was compared to a Binder condition wherein participants received a notebook that contained paper content similar to that contained in PRISM. The sample included 300 older adults at risk for social isolation who lived independently in the community (Mage = 76.15 years). Primary outcome measures included indices of social isolation, social support, loneliness, and well-being. Secondary outcome measures included indices of computer proficiency and attitudes toward technology. Data were collected at baseline and at 6 and 12 months post-randomization. The PRISM group reported significantly less loneliness and increased perceived social support and well-being at 6 months. There was a trend indicating a decline in social isolation. Group differences were not maintained at 12 months, but those in the PRISM condition still showed improvements from baseline. There was also an increase in computer self-efficacy, proficiency, and comfort with computers for PRISM participants at 6 and 12 months. The findings suggest that access to technology applications such as PRISM may enhance social connectivity and reduce loneliness among older adults and has the potential to change attitudes toward technology and increase technology self-efficacy.

  9. Moving from answer finding to sensemaking: Supporting middle school students' online inquiry

    Zhang, Meilan

    Online inquiry, use of the Web as an information source to conduct inquiry for a scientific question, has become increasingly common in middle schools in recent years. However, while valuable Web resources provide unprecedented learning opportunities, easy access to information does not guarantee learning. Previous research has found that middle school students tend to use the Web in a superficial manner. To address the challenges that students face in online inquiry, this study explored several supporting strategies implemented in Digital IdeaKeeper, a scaffolded software tool to help students move from passively finding a ready-made answer to actively making sense of the information they encounter through support for inquiry planning, information search, analysis, and synthesis. This study examined the differences and similarities between regular online inquiry and supported online inquiry performed by several sixth-graders in real classroom settings. Four pairs from a sixth grade class used IdeaKeeper for their online inquiry project, and another four pairs from a different sixth grade class taught by the same teacher used regular online search engines only. Both groups worked on the same science topic-water, and the entire project lasted about four weeks. During that time, students in both groups used computers for about 10-14 days to conduct online research. Multiple sources of data were collected, including video recordings of students' computer activities and conversations, students' artifacts, log files and student final writings. Several themes emerged from the data analysis. First, the findings refer to the importance of providing a structure for students' online inquiry, to promote a more integrated, efficient, continuous, metacognitive and engaging online inquiry. In addition, guidance is important to promote more careful, thorough, and purposeful online reading, Overall, the results suggest that middle school students' online inquiry needs to be

To analyze in mild Alzheimer’s disease (MAD patients, GDS-4 (Reisberg Scale, whether or not some psychophysical tests (PTs support OCT macular findings in the same group of MAD patients reported previously. Methods. Twenty-three MAD patients and 28 age-matched control subjects with mean Mini Mental State Examination of 23.3 and 28.2, respectively, with no ocular disease or systemic disorders affecting vision were included. Best-corrected visual acuity (VA, contrast sensitivity (CS (3, 6, 12, and 18 cpds, color perception (CP, and perception digital test (PDT were tested in one eye of each patient. Results. In comparison with the controls, MAD patients presented (i a significant decrease in VA, PDT, and CS for all spatial frequencies analyzed, especially the higher ones, and (ii a significant increase in unspecific errors on the blue axis (P<0.05 in all instances. In MAD patients, a wide aROC curve was plotted in all PTs. Conclusions. In MAD, CS, VA, and the tritan axis in CP were impaired. The PTs with the greatest predictive value are the higher spatial frequencies in CS and tritan unspecific errors in CP. PT abnormalities are consistent with the structural findings reported in the same MAD patients using OCT.

    2005-04-01

    With the availability of new functional and structural neuroimaging techniques, researchers have begun to localize brain areas that may be dysfunctional in offenders who are aggressive and violent. Our review of 17 neuroimaging studies reveals that the areas associated with aggressive and/or violent behavioral histories, particularly impulsive acts, are located in the prefrontal cortex and the medial temporal regions. These findings are explained in the context of negative emotion regulation, and suggestions are provided concerning how such findings may affect future theoretical frameworks in criminology, crime prevention efforts, and the functioning of the criminal justice system.

    2014-04-01

    In this study, I aim to reveal how Lee Gyoojoons medicine has given birth to a current of learning, the supporting yang current of learning, and describe its historical significance. Before anything, I'd like to throw the question of whether if there were any currents within the traditional Korean medicine. There are no records of medical currents being widely discussed until now in medical history of Korea; however, the current of Lee Jema's sasang medicine is the most noticeable one. Among the contemporaries of Lee Jema, during the late Chosun, there was also another famed medical practitioner called Lee Gyoojoon. Lee Gyoojoon mainly practiced his medicine within Pohang, Gyeongsangbuk-do area, his apprentices have formed a group and have succeeded his medical practice. Based on the analyses of Lee Gyoojoon's apprentices and the Somun Oriental Medical Society, which is known as a successor group to Lee Gyoojoon's medicine today, they are fully satisfying the five requirements to establish a medical current: first, they held Lee Gyoojoon as the first and foremost, representative practitioner of their current; second, they advocate the supporting yang theory suggested by Lee Gyoojoon, which is originated from his theory of Mind; third, books such as the Major Essentials of Huangdi's Internal Classic Plain Questions, and the Double Grinded Medical Mirror, were being used as the main textbooks to educate their students or to practice medicine. Fourth, Lee Gyoojoon's medical ideas were being transcended quite clearly within his group of apprentices, including Seo Byungoh, Lee Wonse, and the Somun Oriental Medical Society. Fifth, Lee Gyoojoon's apprentices were first produced through the Sukgok School, however, nowadays they are being produced through medical groups formed by Lee Wonse, the Somun Oriental Medical Society, regarding the propagation of medical theories, compilation of textbooks, publication of academic journals, etc. Then, what do the existence of the

A sample of 88 patients with colorectal cancer and their partners completed questionnaires approximately 3 and 9 months after diagnosis. The data were analyzed employing dyadic data analytic approaches. In the short-term, spousal active engagement--which involved discussing feelings and engaging in joint problem solving--was positively associated with relationship satisfaction in patients as well as in partners, but only when past spousal support was relatively low. Spousal protective buffering--which involved hiding worries and fears and avoiding talking about the disease--was negatively associated with relationship satisfaction in patients, again only when past spousal support was relatively low. If past spousal support was high, participants rated the quality of their relationship relatively high, regardless of their partner's current support behavior. Over time, past spousal supportiveness was not found to mitigate the negative association between spousal protective buffering and relationship satisfaction. Overall, our results indicate that relationship satisfaction can be maintained if past spousal supportiveness is high even if the partner is currently not very responsive to the individual's needs, at least in the short-term.

    Breast fibromatosis is a rare entity responsible for 0.2% of all solid breast tumors. It has been associated with scars, pregnancy, implants, and familial adenomatous polyposis. We present an interesting case of breast fibromatosis in a 29 year old woman which encroached upon her saline implant and subsequently filled its cavity once the implant was removed. The patient was put on tamoxifen therapy and at 14 month follow-up there was a significant decrease in the size of the mass. Dynamic MRI images are offered for review and current treatment options are discussed.

    Over the last several years, there has been a substantial increase in the number of publications reporting on Internet interventions for mental health and addictions. This paper provides a summary of the recent research on Internet interventions for the most common mental health and addictions concerns-depression, anxiety, alcohol and smoking. There is considerable evidence for the effectiveness of Internet-based interventions targeting depression, anxiety disorders, alcohol use and smoking. Small to moderate effect sizes have been reported for interventions targeting depression, anxiety and alcohol use, and smoking interventions have shown large effects. The addition of human support to depression and anxiety interventions has generally resulted in larger treatments effects, but this trend has not been observed in trials of interventions targeting alcohol use. There is some evidence that online interventions can be as effective as face-to-face therapies, at least for anxiety disorders. Despite a proliferation of research activity in this area, gaps in knowledge remain. Future research should focus on the development and evaluation of interventions for different platforms (e.g. smartphone applications), examining the long-term impacts of these interventions, determining active intervention components and identifying methods for enhancing tailoring and engagement. Careful consideration should be given to the ongoing technical and clinical expertise required to ensure that Internet interventions are delivered safely and professionally in a rapidly changing technology environment.

    Using Green's functions, we reformulate Kirchhoff's laws for a two-component random resistor network in which a fraction p of the resistors has conductance σ- and the remainder have conductance σ+. In this Green's-function formulation (GFF), the current correlation between any two resistors in the network is explicitly taken into account. The GFF yields a linear system equivalent to Kirchhoff's laws but with a smaller number of variables. In the dilute case (pGFF. For general p, a variety of algorithms can be used to solve the GFF linear system. We present the technical details of solving the GFF linear system using the conjugate gradient method (method A). Our extensive numerical work shows that method A consistently requires fewer iterations than solving Kirchhoff's laws directly using the conjugate gradient method (method B). For example, for a 128×128 grid with p>=0.65 and σ-/σ+<=10-4, the number of iterations needed to achieve a precision of 10-10 is more than 100 times smaller in method A than in method B.

    Researchers have consistently documented the relationship between optimism and benefit finding; however, there is a dearth of research on the psychological mechanisms mediating their association. This cross-sectional study sought to elucidate the mediating role of positive reappraisal and social support in the optimism-benefit finding relationship in parents caring for children with developmental disabilities by testing a parallel multiple mediation model. One hundred and forty-six parents caring for children with developmental disabilities completed an online survey assessing optimism, positive reappraisal, social support and benefit finding. Optimism was not directly related to benefit finding but rather influenced it indirectly through positive reappraisal and social support. Specifically, higher levels of optimism predicted greater positive reappraisal and social support, which in turn led to greater benefit finding in parents. These results underscore the importance of targeting parents' perceptions of benefits through both positive reappraisal and social support in order to help them cope with the demands of the caregiving context.

    Background Social support is frequently linked to positive parenting behavior. Similarly, studies increasingly show a link between neighborhood residential environment and positive parenting behavior. However, less is known about how the residential environment influences parental social support. To address this gap, we examine the relationship between neighborhood concentrated disadvantage and collective efficacy and the level and change in parental caregiver perceptions of non-familial social support. Methodology/Principal Findings The data for this study came from three data sources, the Project on Human Development in Chicago Neighborhoods (PHDCN) Study's Longitudinal Cohort Survey of caregivers and their offspring, a Community Survey of adult residents in these same neighborhoods and the 1990 Census. Social support is measured at Wave 1 and Wave 3 and neighborhood characteristics are measured at Wave 1. Multilevel linear regression models are fit. The results show that neighborhood collective efficacy is a significant (ß = .04; SE = .02; p = .03), predictor of the positive change in perceived social support over a 7 year period, however, not of the level of social support, adjusting for key compositional variables and neighborhood concentrated disadvantage. In contrast concentrated neighborhood disadvantage is not a significant predictor of either the level or change in social support. Conclusion Our finding suggests that neighborhood collective efficacy may be important for inducing the perception of support from friends in parental caregivers over time. PMID:22493683

  15. Decision support methods for finding phenotype--disorder associations in the bone dysplasia domain.

    Directory of Open Access Journals (Sweden)

    Razan Paul

    Full Text Available A lack of mature domain knowledge and well established guidelines makes the medical diagnosis of skeletal dysplasias (a group of rare genetic disorders a very complex process. Machine learning techniques can facilitate objective interpretation of medical observations for the purposes of decision support. However, building decision support models using such techniques is highly problematic in the context of rare genetic disorders, because it depends on access to mature domain knowledge. This paper describes an approach for developing a decision support model in medical domains that are underpinned by relatively sparse knowledge bases. We propose a solution that combines association rule mining with the Dempster-Shafer theory (DST to compute probabilistic associations between sets of clinical features and disorders, which can then serve as support for medical decision making (e.g., diagnosis. We show, via experimental results, that our approach is able to provide meaningful outcomes even on small datasets with sparse distributions, in addition to outperforming other Machine Learning techniques and behaving slightly better than an initial diagnosis by a clinician.

    Full Text Available The importance of data mining is increasing exponentially since last decade and in recent time where there is very tough competition in the market where the quality of information and information on time play a very crucial role in decision making of policy has attracted a great deal of attention in the information industry and in society as a whole. In this approach we also use density minimum support so that we reduce the execution time. A frequent superset means it contains more transactions then the minimum support. It utilize the concept that if the item set is not frequent but the superset may be frequent which is consider for the further data mining task. By this approach we can store the transaction on the daily basis, then we provide three different density zone based on the transaction and minimum support which is low (L, Medium (M, High (H. Based on this approach we categorize the item set for pruning. Our approach is based on apriori algorithm but provides better reduction in time because of the prior separation in the data, which is useful for selecting according to the density wise distribution in India. Our algorithm provides the flexibility for improved association and dynamic support. Comparative result shows the effectiveness of our algorithm.

    Evaluation of pharmaceutical agents in children is now conducted earlier in the drug development process. An important consideration for this pediatric use is how to assess and support its safety. This article is a collaborative effort of industry toxicologists to review strategies, challenges, and current practice regarding preclinical safety evaluations supporting pediatric drug development with biopharmaceuticals. Biopharmaceuticals include a diverse group of molecular, cell-based or gene therapeutics derived from biological sources or complex biotechnological processes. The principles of preclinical support of pediatric drug development for biopharmaceuticals are similar to those for small molecule pharmaceuticals and in general follow the same regulatory guidances outlined by the Food and Drug Administration and European Medicines Agency. However, many biopharmaceuticals are also inherently different, with limited species specificity or immunogenic potential which may impact the approach taken. This article discusses several key areas to aid in the support of pediatric clinical use, study design considerations for juvenile toxicity studies when they are needed, and current practices to support pediatric drug development based on surveys specifically targeting biopharmaceutical development. © 2011 Wiley-Liss, Inc.

    Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic disease, which is usually transmitted to humans by tick bites or contact with blood or other infected tissues of livestock. Patients suffering from CCHF demonstrate an extensive spectrum of clinical symptoms. As it can take considerable time from suspecting the disease in hospital until reaching a definitive diagnosis in the laboratory, understanding the clinical symptoms and laboratory findings of CCHF patients is of paramount importance for clinicians. The data were collected from patients who were referred to the Laboratory of Arboviruses and Viral Hemorrhagic Fevers at the Pasteur institute of Iran with a primary diagnosis of CCHF between 1999 and 2012 and were assessed by molecular and serologic tests. Referred patients were divided into two groups: patients with a CCHF positive result and patients with a CCHF negative result. The laboratory and clinical findings of these two groups were then compared. Two-thousand five hundred thirty-six probable cases of CCHF were referred to the laboratory, of which 871 cases (34.3%) were confirmed to be CCHF. Contact with infected humans and animals increased the CCHF infection risk (P important role in patient survival and the application of the findings of this study can prove helpful as a key for early diagnosis.

    2017-05-01

    Full Text Available Direction-of-arrival (DOA estimation has drawn considerable attention in array signal processing, particularly with coherent signals and a limited number of snapshots. Forward–backward linear prediction (FBLP is able to directly deal with coherent signals. Support vector regression (SVR is robust with small samples. This paper proposes the combination of the advantages of FBLP and SVR in the estimation of DOAs of coherent incoming signals with low snapshots. The performance of the proposed method is validated with numerical simulations in coherent scenarios, in terms of different angle separations, numbers of snapshots, and signal-to-noise ratios (SNRs. Simulation results show the effectiveness of the proposed method.

    To assess the level of public support for tobacco control policies and to discuss how these findings could be used to influence the legislative process in the passing of tobacco control law in the country. A cross-sectional study conducted in Kenya between March and May 2007 on a random sample of 2021 (991 men and 1030 women) respondents aged 18 years and above. Interviews were done using a structured questionnaire by a research consultancy firm with long-standing experience in public polling. The majority of respondents supported tobacco control policies as proposed by WHO Framework Convention on Tobacco Control. For example, 95% of the respondents supported smoking restrictions in all enclosed public places and workplaces, 94% supported visible health warnings on tobacco product packages, 83% supported a ban on advertisements of cigarettes and tobacco products and 69% supported a ban on sponsorship of events by tobacco companies. However, 60% perceived that there was very little commitment by legislators to tobacco control. There was overwhelming public support for tobacco control policies and a general view that government was not doing enough in implementing policies to protect the public from tobacco harm. This public opinion poll was used as an advocacy tool to generate support among legislators for national tobacco control law.

    1994-01-01

    The prevalence of temporomandibular joint (TMJ) osteoarthrosis and synovitis was compared in 60 patients with painful chronic locking of the TMJ. 30 patients had reduced molar occlusion, and as controls, 30 age-matched fully dentate patients were examined. Assessment comprised clinical examination (crepitation), tomography (sclerosis and erosions), and arthroscopy (cartilage involvement) of the TMJ. Arthroscopic signs of osteoarthrosis and synovitis were frequent in both groups. The highest frequency of osteoarthrosis was diagnosed by arthroscopy. With regard to clinical signs and symptoms, tomographic signs of osteoarthrosis, and arthroscopic diagnoses, no statistical differences were found between fully dentate subjects and those with reduced molar occlusion. The results do not support the concept that prevention of TMJ osteoarthrosis is an indication for prosthetic replacement of lost molars. 24 refs., 4 tabs.

    To identify the extent to which homes and neighbourhoods of older community-dwelling people are 'supportive'. Cross-sectional survey, in-home observation and interviews involving 202 participants (75-79 years). Measures included SF-36 health-related quality of life and Late Life Function and Disability Instrument (LLFDI) scores, and self-reported home usability, access, safety and neighbourhood. Associations between home and neighbourhood characteristics were assessed using χ(2) -tests, t-tests and Pearson correlations. Older people rated neighbourhood satisfaction highly (3.0 men, 3.2 women; 4 being the highest score). Many homes failed objective adaptability and safety ratings, particularly bathrooms (80% did not have a shower grab rail, 77% did not have non-slip floors); 27% of homes scored ≥8 of 25 possible hazards. There were significant correlations between perceptions of housing and neighbourhood and SF-36 and disability scores. Many homes and neighbourhoods may not accommodate increased frailty or disability of older people into the future. © 2012 The Authors. Australasian Journal on Ageing © 2012 ACOTA.

The NIH informationist programme was designed to enhance the library's service capacity. Over time, the steps for introducing the service to new groups were formalized to ensure support by leadership, the team being served and the library. Job responsibilities also evolved from traditional library roles to a wide range of knowledge management activities. The commitment by the informationist, the team and the library to continuous learning is critical to the programme's success. RESULTS / OUTCOMES: NIH scientists reported that informationists saved them time and contributed to teamwork with expert searching and point-of-need instruction. Process evaluation helped refine the programme. High-level, preliminary outcomes were identified from a survey of scientists receiving informationist services, along with key informant interviews. Process evaluation examined service implementation, informationists' training and service components. Anecdotal evidence has also indicated a favourable response to the programme.

    Some parts of Iran are considered as one of the driest regions of the world, where water is a limiting factor for lasting life therefore using seasonal floodwaters is very important in these arid regions. On the other hand, special attention has been paid to artificial groundwater recharge in these regions. Floodwater spreading on the permeable terrain is one of the flood control and utilization methods. Determination of appropriate site for water spreading is one of the most important stages of this project. Parameters considered in the selection of groundwater artificial recharge locations are diverse and complex. These factors consist of earth sciences (geology, geomorphology and soils), hydrology (runoff, sediment yield, infiltration and groundwater conditions) and socio-economic aspects (irrigated agriculture, flood damage mitigation, environment, job creation and so on). Hence, decision making depends on criteria of diverse nature. The goal of this study is defining a Decision Support System for floodwater site selection in Shahriary area. Four main criteria were selected in this research which are floodwater characters, infiltration, water applications and flood damage. In order to determine the weight of factors, Analytical Hierarchy Process was used. The results showed that soil texture and floodwater volume of infiltration are the most important factors. After providing output maps which had been defined in five scenarios, Kappa Index was used to evaluate the model. Based on the obtained results, the maps showed an acceptable agreement with control zones.

    In an age of rising impact of online communication in social network sites (SNS), emotional interaction is neither limited nor restricted by time or space. Bereavement extends to the anonymity of cyberspace. What role does virtual interaction play in SNS in dealing with the basic human emotion of grief caused by the loss of a beloved person? The analysis laid out in this article provides answers in light of an interdisciplinary perspective on online bereavement. Relevant lines of research are scrutinized. After laying out the theoretical spectrum for the study, hypotheses based on a prior in-depth qualitative content analysis of 179 postings in three different German online bereavement platforms are proposed and scrutinized in a quantitative content analysis (2127 postings from 318 users). Emotion regulation patterns in SNS and similarities as well as differences in online bereavement of children, adolescents and adults are revealed. Large-scale quantitative findings into central motives, patterns, and restorative effects of online shared bereavement in regulating distress, fostering personal empowerment, and engendering meaning are presented. The article closes with implications for further analysis in memorialization practices.

    The traditional method of short-term tidal current prediction, harmonic method, typically needs more than 18 years of history records. The method in the article uses univariate feature selection and F-test to reduce the dimension of the data fed to support vector regressor, which reduces the need of history records to less than a year. Model parameters are selected by grid searching and cross-validation. History records from two datasets are used to build prediction models, spanning 3 months and 1 year respectively. Mean average errors of both datasets after normalizing are less than 0.05.

  17. Inspection of ferromagnetic support structures from within alloy 800 steam generator tubes using pulsed eddy current

    Buck, Jeremy Andrew

    Nondestructive testing is a critical aspect of component lifetime management. Nuclear steam generator (SG) tubes are the thinnest barrier between irradiated primary heat transport system and the secondary heat transport system, whose components are not rated for large radiation fields. Conventional eddy current testing (ECT) and ultrasonic testing are currently employed for inspecting SG tubes, with the former doing most inspections due to speed and reliability based on an understanding of how flaws affect coil impedance parameters when conductors are subjected to harmonically induced currents. However, when multiple degradation modes are present simultaneously near ferromagnetic materials, such as tube fretting, support structure corrosion, and magnetite fouling, ECT reliability decreases. Pulsed eddy current (PEC), which induces transient eddy currents via square wave excitation, has been considered in this thesis to simultaneously examine SG tube and support structure conditions. An array probe consisting of a central driver, coaxial with the tube, and an array of 8 sensing coils, was used in this thesis to perform laboratory measurements. The probe was delivered from the inner diameter (ID) of the SG tube, where support hole diameter, tube frets, and 2D off-centering were varied. When considering two variables simultaneously, scores obtained from a modified principal components analysis (MPCA) were sufficient for parameter extraction. In the case of hole ID variation with two dimensional tube off-centering (three parameters), multiple linear regression (MLR) of the MPCA scores provided good estimates of parameters. However, once a fourth variable, outer diameter tube frets, was introduced, MLR proved insufficient. Artificial neural networks (ANNs) were investigated in order to perform pattern recognition on the MPCA scores to simultaneously extract the four measurement parameters from the data. All models throughout this thesis were created and validated using

    Nuclear steam generators (SGs) are a critical component for ensuring safe and efficient operation of a reactor. Life management strategies are implemented in which SG tubes are regularly inspected by conventional eddy current testing (ECT) and ultrasonic testing (UT) technologies to size flaws, and safe operating life of SGs is predicted based on growth models. ECT, the more commonly used technique, due to the rapidity with which full SG tube wall inspection can be performed, is challenged when inspecting ferromagnetic support structure materials in the presence of magnetite sludge and multiple overlapping degradation modes. In this work, an emerging inspection method, pulsed eddy current (PEC), is being investigated to address some of these particular inspection conditions. Time-domain signals were collected by an 8 coil array PEC probe in which ferromagnetic drilled support hole diameter, depth of rectangular tube frets and 2D tube off-centering were varied. Data sets were analyzed with a modified principal components analysis (MPCA) to extract dominant signal features. Multiple linear regression models were applied to MPCA scores to size hole diameter as well as size rectangular outer diameter tube frets. Models were improved through exploratory factor analysis, which was applied to MPCA scores to refine selection for regression models inputs by removing nonessential information.

    Full Text Available Despite preference for community-based living, large numbers of people with psychiatric disabilities live in nursing homes throughout the US. Community-based services for this population are limited by public policy and service system barriers. This paper summarizes these barriers and presents the second phase of a participatory action research project jointly developed by university-based researchers and two Centers for Independent Living. A qualitative case study methodology was used to understand the experiences of three individuals with psychiatric disabilities reintegrating into the community from nursing homes. Findings revealed themes of social isolation, participation in virtual communities, variability of impairment experiences and unmet needs for community supports. In addition to thematic findings, action products were generated for the benefit of community partners. These products included national best practice resources and a needs assessment survey tool. Study findings and products point to specific systems change and policy recommendations to better support community reintegration for this population. These recommendations are discussed in light of U.S. healthcare reform and broader disability advocacy efforts.

    The magnetic-elasticity buckling problem of a current plate under the action of a mechanical load in a magnetic field was studied by using the Mathieu function. According to the magnetic-elasticity non-linear kinetic equation, physical equations, geometric equations, the expression for Lorenz force and the electrical dynamic equation, the magnetic-elasticity dynamic buckling equation is derived. The equation is changed into a standard form of the Mathieu equation using Galerkin's method. Thus, the buckling problem can be solved with a Mathieu equation. The criterion equation of the buckling problem also has been obtained by discussing the eigenvalue relation of the coefficients λ and η in the Mathieu equation. As an example, a thin plate simply supported at three edges is solved here. Its magnetic-elasticity dynamic buckling equation and the relation curves of the instability state with variations in some parameters are also shown in this paper. The conclusions show that the electrical magnetic forces may be controlled by changing the parameters of the current or the magnetic field so that the aim of controlling the deformation, stress, strain and stability of the current carrying plate is achieved.

    With an increasing emphasis on evidence-based practice, the need for social work researchers and practitioners to adapt empirically supported interventions for new populations and cultures is essential. However, social work suffers from a lack of guidance and detailed examples of intervention adaptations that may not proceed "by the book" and actually falter but recover. Many of these situations result from lack of attention to setting and context even when researchers believe they have full stakeholder buy-in. This article presents process evaluation findings from an intervention adaptation called Proyecto Puentes that allowed for self-correction and successful intervention development.

    Full Text Available Abstract Background Women's return to work can be a significant barrier to continued breastfeeding. Workplace policies and practices to promote and support continued, and longer duration of, breastfeeding are important. In the context of the introduction of a new breastfeeding policy for Area Health Services in New South Wales, Australia, a baseline survey was conducted to describe current practices and examine women's reports of perceived organisational support on breastfeeding intention and practice. Methods A cross sectional survey of female employees of the Sydney South West Area Health Service was conducted in late 2009. A mailed questionnaire was sent to 998 eligible participants who had taken maternity leave over the 20-month period from January 2008 to August 2009. The questionnaire collected items assessing breastfeeding intentions, awareness of workplace policies, and the level of organisational and social support available. For those women who had returned to work, further questions were asked to assess the perceptions and practices of breastfeeding in the work environment, as well as barriers and enabling factors to combining breastfeeding and work. Results Returning to work was one of the main reasons women ceased breastfeeding, with 60 percent of women intending to breastfeed when they returned to work, but only 40 percent doing so. Support to combine breastfeeding and work came mainly from family and partners (74% and 83% respectively, with little perceived support from the organisation (13% and human resources (6%. Most women (92% had received no information from their managers about their breastfeeding options upon their return to work, and few had access to a room specially designated for breastfeeding (19%. Flexible work options and lactation breaks, as well as access to a private room, were identified as the main factors that facilitate breastfeeding at work. Conclusions Enabling women to continue breastfeeding at work has

    Full Text Available Questions: Is Kinesio Taping more effective than a sham taping/placebo, no treatment or other interventions in people with musculoskeletal conditions? Is the addition of Kinesio Taping to other interventions more effective than other interventions alone in people with musculoskeletal conditions? Design: Systematic review of randomised trials. Participants: People with musculoskeletal conditions. Intervention: Kinesio Taping was compared with sham taping/placebo, no treatment, exercises, manual therapy and conventional physiotherapy. Outcome measures: Pain intensity, disability, quality of life, return to work, and global impression of recovery. Results: Twelve randomised trials involving 495 participants were included in the review. The effectiveness of the Kinesio Taping was tested in participants with: shoulder pain in two trials; knee pain in three trials; chronic low back pain in two trials; neck pain in three trials; plantar fasciitis in one trial; and multiple musculoskeletal conditions in one trial. The methodological quality of eligible trials was moderate, with a mean of 6.1 points on the 10-point PEDro Scale score. Overall, Kinesio Taping was no better than sham taping/placebo and active comparison groups. In all comparisons where Kinesio Taping was better than an active or a sham control group, the effect sizes were small and probably not clinically significant or the trials were of low quality. Conclusion: This review provides the most updated evidence on the effectiveness of the Kinesio Taping for musculoskeletal conditions.

    This study examined the impact of computer simulation and supported science learning on a teacher's understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers' concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains, with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21) gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported science learning can have a positive effect on concept attainment in teachers.

    A program to demonstrate Solvent Refined Coal (SRC) technology has been initiated by the US Department of Energy (DOE) in partnership with two industrial groups. Project management responsibility has been assigned to the Oak Ridge Operations Office (ORO) of DOE. ORO requested that the Oak Ridge National Laboratory assess current research and development (R and D) activities and develop recommendations for those activities that might contribute to successful completion of the SRC demonstration plant projects. The objectives of this final report are to discuss in detail the problem areas in SRC; to discuss the current and planned R and D investigations relevant to the problems identified; and to suggest appropriate R and D activities in support of designs for the SRC demonstration plants. Four types of R and D activities are suggested: continuation of present and planned activities; coordination of activities and results, present and proposed; extension/redirection of activities not involving major equipment purchase or modifications; and new activities. Important examples of the first type of activity include continuation of fired heater, slurry rheology, and slurry mixing studies at Ft. Lewis. Among the second type of activity, coordination of data acquisition and interpretation is recommended in the areas of heat transfer, vapor/liquid equilibria, and physical properties. Principal examples of recommendations for extension/redirection include screening studies at laboratory scale on the use of carbonaceous precoat (e.g., anthracite) infiltration, and 15- to 30-day continuous tests of the Texaco gasifier at the Texaco Montebello facility (using SRC residues).

    Estimation of remaining useful life (RUL) is helpful to manage life cycles of machines and to reduce maintenance cost. Support vector machine (SVM) is a promising algorithm for estimation of RUL because it can easily process small training sets and multi-dimensional data. Many SVM based methods have been proposed to predict RUL of some key components. We did a literature review related to SVM based RUL estimation within a decade. The references reviewed are classified into two categories: improved SVM algorithms and their applications to RUL estimation. The latter category can be further divided into two types: one, to predict the condition state in the future and then build a relationship between state and RUL; two, to establish a direct relationship between current state and RUL. However, SVM is seldom used to track the degradation process and build an accurate relationship between the current health condition state and RUL. Based on the above review and summary, this paper points out that the ability to continually improve SVM, and obtain a novel idea for RUL prediction using SVM will be future works.

    Despite their potential to significantly improve health care, advanced clinical decision support (CDS) capabilities are not widely available in the clinical setting. An important reason for this limited availability of CDS capabilities is the application-specific and institution-specific nature of most current CDS implementations. Thus, a critical need for enabling CDS capabilities on a much larger scale is the development and adoption of standards that enable current and emerging CDS resources to be more effectively leveraged across multiple applications and care settings. Standards required for such effective scaling of CDS include (i) standard terminologies and information models to represent and communicate about health care data; (ii) standard approaches to representing clinical knowledge in both human-readable and machine-executable formats; and (iii) standard approaches for leveraging these knowledge resources to provide CDS capabilities across various applications and care settings. A number of standards do exist or are under development to meet these needs. However, many gaps and challenges remain, including the excessive complexity of many standards; the limited availability of easily accessible knowledge resources implemented using standard approaches; and the lack of tooling and other practical resources to enable the efficient adoption of existing standards. Thus, the future development and widespread adoption of current CDS standards will depend critically on the availability of tooling, knowledge bases, and other resources that make the adoption of CDS standards not only the right approach to take, but the cost-effective path to follow given the alternative of using a traditional, ad hoc approach to implementing CDS.

    The aim of this study was to evaluate microbiological findings and aMMP-8 level of peri-implant mucositis (M) and peri-implantitis (P) in patients undergoing supportive implant therapy (SIT). Eighty-nine patients with 171 implants were included. The case definitions were as follows: M: PPD ≥4mm, BOP; P: PPD≥4mm, BOP, radiographic bone loss ≥3.5mm. Samples of peri-implant sulcular fluid (PISF) were taken from all peri-implant pockets at each implant to detect periodontal pathogens using PCR and aMMP-8 level with ELISA. Only Treponema denticola (Td) and Prevotella intermedia (Pi) showed significantly higher prevalence in P (healthy implants [HI]: Td=27%, Pi=17%; M: Td=26%, Pi=15%; P: Td and Pi=50%; P<0.05). The mean aMMP-8 level at implant sites did not show any significant difference (P=0.05) among HI (5.2±8.1), M (9.9±19.0), and P (4.9±7.7). Microbiological findings and aMMP-8 levels are not reliable criteria to distinguish between HI, M, and P in patients undergoing SIT.

    The subacute spongiform encephalopathies are prion diseases characterized by acute and rapid neurodegeneration that lead to the death of the patient within months to a few years. The epidemiology of CJD is complicated and the frequency in Mexico is unknown. We aim to describe the cases of prion disease in Mexico. Consecutive patients who met the diagnostic criteria by the WHO were enrolled. We describe 26 patients with clinical manifestations, imaging and laboratory studies compatible with prion disease. The mean age at onset was 52 years old. The main clinical manifestations were cognitive alterations (69%) followed by extrapyramidal movements (50%), abnormal cerebellar function (46%), behavioral alterations (46%), myoclonus (46%), and mood depression (23%), among other features. Half of the patients progressed rapidly to a state of akinetic mutism (53%). Only 2 (7.6%) patients had a family history of a similar disease. Time interval between onset and diagnosis varied between 71 days to 24 months, with a median of 6 months. The classical bilateral basal ganglia hyperintensities were present in the very early stage of the disease. Protein 14-3-3 immuneassay in the CSF was positive in all measured cases. Bilateral basal ganglia hyperintensities was the most important early finding, while protein 14-3-3 was a late finding and the results were usually obtained after the patient was discharged. Around 1.5 cases of CJD cases per year are reported in our country. When suspected, MRI can support the diagnosis earlier than other studies.

    Full Text Available Objective: Vulvovaginitis candidiasis and trichomoniasis constitute at least 50% of infectious vaginitis cases. The aim of this study was to determine the prevalence, risk factors, and clinical findings of candidiasis and trichomoniasis in women supported by selected health centers of Tabriz, Iran. Materials and Methods: This was a cross-sectional study, in which 1000 women who had the study criteria were selected by random sampling. In addition, 12 health centers of Tabriz were selected for this study. A questionnaire was used to obtain their personal and reproductive information, checklist for clinical observations, and culture methods (sabouraud dextrose agar and diamond for diagnose vaginal infections. Results: The prevalence of candidiasis and trichomoniasis were 25.2 and 9.2%, respectively. Findings showed that candidiasis infection, history of diseases, vaginal pH, number of coitus, number of delivery, and number of vaginal delivery, breast feeding status, method of last delivery, and contraceptive methods are risk factors for candidacies. Moreover, age at marriage, personal health, sexual hygiene, and vaginal pH are risk factors for trichomoniasis. A statistically significant relationship was observed between candidiasis and clinical findings, such as pruritus, pruritus during coitus, burning sensation with coitus, dysuria in woman and her husband, dyspareunia, low abdominal pain, urinal symptoms, vaginal status, amount of discharge, consistency appearance, and color of discharges. Furthermore, a significant relationship was observed between trichomoniasis and dysuria, and appearance and color of vaginal discharge. Conclusion: Due to the high prevalence of candidiasis, trichomoniasis infections, and infected women as asymptomatic carriers, it seems necessary to pay more attention to these infections and make efforts for their prevention.

    Chronic pain and substance use can strain the supportive relationships of persons with serious chronic illness, which may increase the likelihood of receiving negative, rather than positive, social support from informal caregivers and social network members. To our knowledge, this is the first study to longitudinally examine the effects of chronic pain and substance use on negative social support. The sample (N = 383) comprised disadvantaged, primarily African-American, persons living with HIV/AIDS with a history of injection drug use, 32.4% of whom reported frequent or constant pain in the prior 6 months. Using factor analysis and structural equation modeling, current substance use and greater levels of chronic pain positively predicted negative social support 12 months later, after controlling for baseline negative support, viral load, age and sex. We also found a significant interaction effect such that among those not using substances, there was a significant positive association between pain and negative support, but no such association among those currently using substances. The findings emphasize the importance of treatment of chronic pain and substance use in the supportive functioning of social networks of a disadvantaged population with serious chronic conditions and persistent health disparities.

    Female pelvic organ prolapse is quantified on clinical examination using the pelvic organ prolapse quantification system of the International Continence Society (ICS POP-Q). Pelvic organ descent on ultrasound is strongly associated with symptoms of prolapse, but associations between clinical and ultrasound findings remain unclear. This study was designed to compare clinical examination and imaging findings, especially regarding cut-offs for the distinction between normal pelvic organ support and prolapse. This was a retrospective study using 839 archived datasets of women referred to a tertiary urogynecological center for symptoms of lower urinary tract and pelvic floor dysfunction between June 2011 and May 2013. The main outcome measures were the maximum downward displacement of the anterior vaginal wall (point Ba), the cervix (point C) and the posterior vaginal wall (point Bp), the length of the genital hiatus (Gh) and the length of the perineal body (Pb), as defined by the ICS POP-Q; explanatory parameters were measures of pelvic organ descent on translabial ultrasound, ascertained by offline volume data analysis at a later date, by an operator blinded to all other data. Full datasets were available for 825 women. On clinical examination, 646 (78.3%) were found to have prolapse of at least POP-Q Stage 2. All coordinates on clinical examination were strongly associated with the ultrasound measurements of pelvic organ descent (P POP-Q (Ba ≥ -0.5 and cystocele ≥ 10 mm below the symphysis pubis, C ≥ -5 and uterine position of 15 mm above the symphysis pubis, Bp ≥ -0.5 and rectocele ≥ 15 mm below the symphysis pubis) are plausible and mutually consistent.

    Health warnings labels (HWLs) have the potential to effectively communicate the health risks of smoking to smokers and non-smokers, and encourage smokers to quit. This study sought to examine whether non-smokers in China notice the current text-only HWLs and whether they support adding more health information and including pictures on HWLs. Adult non-smokers (n = 1324) were drawn from Wave 4 (September 2011-November 2012) of the International Tobacco Control (ITC) China Survey. The proportion of non-smokers who noticed the HWLs, and supported adding more health information and pictures to the HWLs was examined. Additionally, the relation between non-smokers' demographic characteristics, including whether they had a smoking partner, their number of smoking friends, and noticing the HWLs and support for adding health information and pictures was examined. Because the HWLs changed during the survey period (April 2012), differences between non-smokers who completed the survey before and after the change were examined. 12.2% reported they noticed the HWLs often in the last month. The multivariate model, adjusting for demographics showed that respondents with a smoking partner (OR = 2.41, 95% CI 1.42-4.13, p = 0.001) noticed the HWLs more often. 64.8% of respondents agreed that the HWLs should have more information, and 80.2% supported including pictures. The multivariate model showed that non-smokers who completed the survey after the HWLs were implemented (OR = 0.63, 95% CI 0.40-0.99, p = 0.04) were less likely to support adding more health information. The multivariate model showed a significant relation between having a smoking partner and supporting pictorial HWLs (OR = 2.03, 95% CI 1.24-3.33, p = 0.005). The findings indicate that the Chinese HWLs are noticed by a minority of non-smokers and that non-smokers strongly support strengthening the Chinese warning labels with more health information and pictures. Additionally, because the HWLs are noticed

    Positive Behavioral Interventions and Supports (PBIS) is a universal, school-wide prevention strategy that is currently implemented in over 7,500 schools to reduce disruptive behavior problems. The present study examines the impact of PBIS on staff reports of school organizational health using data from a group-randomized controlled effectiveness trial of PBIS conducted in 37 elementary schools. Longitudinal multilevel analyses on data from 2,596 staff revealed a significant effect of PBIS on the schools' overall organizational health, resource influence, staff affiliation, and academic emphasis over the 5-year trial; the effects on collegial leadership and institutional integrity were significant when implementation fidelity was included in the model. Trained schools that adopted PBIS the fastest tended to have higher levels of organizational health at baseline, but the later-implementing schools tended to experience the greatest improvements in organizational health after implementing PBIS. This study indicated that changes in school organizational health are important consequences of the PBIS whole-school prevention model, and may in turn be a potential contextual mediator of the effect of PBIS on student performance.

  15. A Phylogenetic Comparative Study of Bantu Kinship Terminology Finds Limited Support for Its Co-Evolution with Social Organisation.

    The classification of kin into structured groups is a diverse phenomenon which is ubiquitous in human culture. For populations which are organized into large agropastoral groupings of sedentary residence but not governed within the context of a centralised state, such as our study sample of 83 historical Bantu-speaking groups of sub-Saharan Africa, cultural kinship norms guide all aspects of everyday life and social organization. Such rules operate in part through the use of differing terminological referential systems of familial organization. Although the cross-cultural study of kinship terminology was foundational in Anthropology, few modern studies have made use of statistical advances to further our sparse understanding of the structuring and diversification of terminological systems of kinship over time. In this study we use Bayesian Markov Chain Monte Carlo methods of phylogenetic comparison to investigate the evolution of Bantu kinship terminology and reconstruct the ancestral state and diversification of cousin terminology in this family of sub-Saharan ethnolinguistic groups. Using a phylogenetic tree of Bantu languages, we then test the prominent hypothesis that structured variation in systems of cousin terminology has co-evolved alongside adaptive change in patterns of descent organization, as well as rules of residence. We find limited support for this hypothesis, and argue that the shaping of systems of kinship terminology is a multifactorial process, concluding with possible avenues of future research.

    Lyons, Anthony

    2016-02-01

    This study examines different types and sources of social support in relation to psychological distress levels among older Australian gay men. A national community-based survey was conducted involving 242 gay-identified men aged 50 years and older. In univariable regressions, psychological distress was less likely if men were receiving emotional support, practical support, or had a sense of belonging, and also if they had a greater number of close friends and received some or a lot of support from family and gay friends but not from straight friends. Of all these factors, a multivariable regression showed that receiving emotional support was the only significant independent factor. Emotional support appears to play a greater role in the mental health of older gay men than many other types and sources of support. Ensuring access to emotional support may need to be considered when promoting healthier aging among gay men.

    Data from a prospective longitudinal study were used to investigate whether hopelessness mediates the association between social support and depression, as hypothesized by L. Y. Abramson, G. I. Metalsky, and L. B. Alloy (1989). Measures of hopelessness, social support, and depression were administered to 103 HIV-infected men and readministered 6 months later. Findings indicated that low baseline social support predicted increases in hopelessness and depression. Increases in hopelessness predicted increases in depression after controlling for baseline social support. Low baseline social support did not predict increased depression when hopelessness was controlled statistically.

    Full Text Available Abstract Background Sixty percent of eating disorders do not meet criteria for anorexia- or bulimia nervosa, as defined by the Diagnostic and Statistical Manual version 4 (DSM-IV. Instead they are diagnosed as ‘eating disorders not otherwise specified’ (EDNOS. Discrepancies between criteria and clinical reality currently hampering eating disorder diagnoses in the DSM-IV will be addressed by the forthcoming DSM-V. However, future diagnoses for eating disorders will rely on current advances in the fields of neuroimaging and genetics for classification of symptoms that will ultimately improve treatment. Discussion Here we debate the classification issues, and discuss how brain imaging and genetic discoveries might be interwoven into a model of eating disorders to provide better classification and treatment. The debate concerns: a current issues in the classification of eating disorders in the DSM-IV, b changes proposed for DSM-V, c neuroimaging eating disorder research and d genetic eating disorder research. Summary We outline a novel evidence-based ‘impulse control’ spectrum model of eating disorders. A model of eating disorders is proposed that will aid future diagnosis of symptoms, coinciding with contemporary suggestions by clinicians and the proposed changes due to be published in the DSM-V.

    Sonography of the knee has gained in significance in the diagnosis of the meniscus; experimental and clinical studies have demonstrated that the normal and pathological anatomy of the meniscus can be visualized on a sonogram. The aim of this comparative investigation is to evaluate sonographic lesion diagnosis in comparison with arthroscopic findings, using a standardized examination method. Two hundred and six knee joints were first scanned sonographically using a 7.5 MHz sector transducer. The examining doctor had neither anamnestic nor clinical information in advance. On the following day, the joints were examined arthroscopically, without the findings of the day before being available to the examiner. When the findings were compared, the sensitivity of sonographic diagnosis of lesions was found to be 82.2% and its specificity 87.6%. The patients were of varying ages and had varying anamneses. The results show that sonography of the meniscus is a valuable diagnostic help when the knee-joint symptoms are not clear, given that the correct technical equipment and sufficient experience with this form of examination are at hand. The advantage of sonography is that, in contrast to arthroscopy, it is noninvasive and easily available.

    It is increasingly evident that not only breast cancer cells, but also the tissue embedding these cells: the tumor microenvironment, plays an important role in tumor progression, metastasis formation and treatment sensitivity. This review focuses on the current knowledge of processes by which the microenvironment affects breast cancer, including formation of the metastatic niche, metabolic stimulation, stimulation of tumor cell migration, immune modulation, angiogenesis and matrix remodeling. The number of drugs targeting key factors in these processes is expanding, and the available clinical data is increasing. Therefore current strategies for intervention and prediction of treatment response are outlined. At present, targeting the formation of the metastatic niche and metabolic stimulation by the breast cancer microenvironment, are already showing clinical efficacy. Intervening in the stimulation of tumor cell migration and immune modulation by the microenvironment upcoming fields of great research interest. In contrast, targeting microenvironmental angiogenesis or matrix remodeling appears to be of limited clinical relevance in breast cancer treatment so far. Further research is warranted to optimize intervention strategies and develop predictive tests for the relevance of targeting involved factors within the microenvironment in order to optimally personalize breast cancer treatment.

    This study aimed to survey childcare support being undertaken by nursery school teachers in Japan and to identify the theories and skills necessary for nursery school teachers to carry out childcare support in the future. In 2007, a postal questionnaires was sent to 1200 teachers at 850 nursery schools, with responses from 712 teachers from 456 nursery schools. In terms of knowledge and skills considered necessary by nursery school teachers in local childcare support centers, 'knowledge and skills of giving advice' was the most common response, followed by 'understanding of children's growth and development'. Nursery school teachers need to receive sufficient education before and after graduation to gain these skills. It is also clear that there is a need for nursery school teachers to make use of their expertise by co-ordinating collaboration among professionals and in the community.

  12. Current Directions in Adding Value to Earth Observation Products for Decision Support

    2015-12-01

    Natural resource managers and infrastructure planners face increasingly complex challenges, given competing demands for resources and changing conditions due to climate and land use change. These pressures create demand for high-quality, timely data; for both one-time decision support and long-term monitoring; and for techniques to articulate the value of resources in monetary and nonmonetary terms. To meet the need for data, the U.S. government invests several billion dollars per year in Earth observations collected from satellite, airborne, terrestrial, and ocean-based systems. Earth observation-based decision support is coming of age; user surveys show that these data are used in an increasing variety of analyses. For example, since the U.S. Department of the Interior/U.S. Geological Survey's (USGS) 2008 free and open data policy for the Landsat satellites, downloads from the USGS archive have increased from 20,000 Landsat scenes per year to 10 million per year and climbing, with strong growth in both research and decision support fields. However, Earth observation-based decision support still poses users a number of challenges. Many of those Landsat downloads support a specialized community of remote sensing scientists, though new technologies promise to increase the usability of remotely sensed data for the larger GIS community supporting planning and resource management. Serving this larger community also requires supporting the development of increasingly interpretive products, and of new approaches to host and update products. For example, automating updates will add value to new essential climate variable products such as surface water extent and wildfire burned area extent. Projections of future urbanization in the southeastern U.S. are most useful when long-term land cover trends are integrated with street-level community data and planning tools. The USGS assessment of biological carbon sequestration in vegetation and shallow soils required a significant

    Plain packaging (PP) for tobacco products was fully implemented in Australia on 1 December 2012 along with larger graphic health warnings. Using longitudinal data from the Australian arm of the ITC Four Country Survey, we examined attitudes to the new packs before and after implementation, predictors of attitudinal change, and the relationship between support and quitting activity. A population-based cohort study design, with some cross-sectional analyses. Surveys of Australian smokers assessed attitudes to PP at four time points prior to implementation (from 2007 to 2012) and one post-implementation wave collected (early/mid-2013). Trend analysis showed a slight rise in opposition to PP among smokers in the waves leading up to their implementation, but no change in support. Support for PP increased significantly after implementation (28.2% pre vs 49% post), such that post-PP more smokers were supportive than opposed (49% vs 34.7%). Multivariate analysis showed support either before or after implementation was predicted by belief in greater adverse health impacts of smoking, desire to quit and lower addiction. Among those not supportive before implementation, having no clear opinion about PP (versus being opposed) prior to the changes also predicted support post-implementation. Support for PP was prospectively associated with higher levels of quitting activity. Since implementation of PP along with larger warnings, support among Australian smokers has increased. Support is related to lower addiction, stronger beliefs in the negative health impacts of smoking, and higher levels of quitting activity. Published by the BMJ Publishing Group Limited.

    Full Text Available This paper deals with a three-dimensional non-destructive evaluation of partially conductive cracks from eddy current testing signals. An SUS316L plate specimen containing a crack is non-destructively inspected by the eddy current method using numerical simulations. An extensive database of eddy current response signals is prepared while dimensional parameters of a crack together with its partial conductivity are varied in wide ranges. A Support Vector Machine classification algorithm is employed to solve the electromagnetic inverse problem. The acquired signals are employed for training the algorithm and for testing its performance. It is demonstrated that the Support Vector Machine algorithm is able to properly classify detected defects into proper classes with very high probability even the partial conductivity of a detected crack together with its width are unknown.

    The ortholog conjecture posits that orthologous genes are functionally more similar than paralogous genes. This conjecture is a cornerstone of phylogenomics and is used daily by both computational and experimental biologists in predicting, interpreting, and understanding gene functions. A recent study, however, challenged the ortholog conjecture on the basis of experimentally derived Gene Ontology (GO) annotations and microarray gene expression data in human and mouse. It instead proposed that the functional similarity of homologous genes is primarily determined by the cellular context in which the genes act, explaining why a greater functional similarity of (within-species) paralogs than (between-species) orthologs was observed. Here we show that GO-based functional similarity between human and mouse orthologs, relative to that between paralogs, has been increasing in the last five years. Further, compared with paralogs, orthologs are less likely to be included in the same study, causing an underestimation in their functional similarity. A close examination of functional studies of homologs with identical protein sequences reveals experimental biases, annotation errors, and homology-based functional inferences that are labeled in GO as experimental. These problems and the temporary nature of the GO-based finding make the current GO inappropriate for testing the ortholog conjecture. RNA sequencing (RNA-Seq) is known to be superior to microarray for comparing the expressions of different genes or in different species. Our analysis of a large RNA-Seq dataset of multiple tissues from eight mammals and the chicken shows that the expression similarity between orthologs is significantly higher than that between within-species paralogs, supporting the ortholog conjecture and refuting the cellular context hypothesis for gene expression. We conclude that the ortholog conjecture remains largely valid to the extent that it has been tested, but further scrutiny using more and

    A rich body of theory has been developed to predict the effects of plant diversity on communities at higher trophic levels and the mechanisms underpinning such effects. However, there are currently a number of key gaps in knowledge that have hindered the development of a predictive framework of plant diversity effects on consumers. For instance, we still know very little about how the magnitude of plant trait variation (e.g. intra-specific vs. inter-specific), as well as the identity and combined effects of plant, herbivore and natural enemy traits, mediate plant diversity effects on consumers. Moreover, the fine-scale mechanisms (e.g. changes in consumer behaviour or recruitment responses) underlying such diversity effects in many cases remain elusive or have been overlooked. In addition, most studies of plant diversity effects on associated consumers have been developed under a static, unidirectional (bottom-up) framework of effects on herbivores and predators without taking into account the potential for dynamic feedbacks across trophic levels. Here we seek to address these key gaps in knowledge as well as to capitalize on recent advances and emerging frameworks in plant biodiversity research. In doing so, we provide new insights as well as recommendations which will stimulate new research and advance this field of study.

    Spinal cord injury (SCI) can cause severe traumatic injury to the central nervous system (CNS). Current therapeutic effects achieved for SCI in clinical medicine show that there is still a long way to go to reach the desired goal of full or significant functional recovery. In basic medical research, however, cell transplantation, gene therapy, application of cytokines, and biomaterial scaffolds have been widely used and investigated as treatments for SCI. All of these strategies when used separately would help rebuild, to some extent, the neural circuits in the lesion area of the spinal cord. In light of this, it is generally accepted that a combined treatment may be a more effective strategy. This review focuses primarily on our recent series of work on transplantation of Schwann cells and adult stem cells, and transplantation of stem cell-derived neural network scaffolds with functional synapses. Arising from this, an artificial neural network (an exogenous neuronal relay) has been designed and fabricated by us-a biomaterial scaffold implanted with Schwann cells modified by the neurotrophin-3 (NT-3) gene and adult stem cells modified with the TrkC (receptor of NT-3) gene. More importantly, experimental evidence suggests that the novel artificial network can integrate with the host tissue and serve as an exogenous neuronal relay for signal transfer and functional improvement of SCI.

    To assess the impact of visual impairment and blindness on the incident use of community support services in the Blue Mountains Eye Study. Population-based cohort. Of 3654 baseline participants (1992-1994), 2334, 1952, and 1149 were re-examined after 5, 10, and 15 years, respectively. Incident visual impairment was defined as subsequent development of visual impairment (visual acuity visual acuity ≥20/40 at baseline. Community support service use included regular use of Meals on Wheels, Home Care, or community nurse services. Informal support included assistance from family or friends. Discrete logistic regression models with time-dependent study and outcome variables were used to assess associations between visual impairment and subsequent use of support, adjusted for potential confounders. Among participants with bilateral visual impairment at baseline, incident use of community services over 5-15 years was 41.7% compared to 19.4% in those without visual impairment at baseline (odds ratio, 1.39; 95% confidence interval, 0.54-3.60). Persons with incident bilateral visual impairment were more likely to subsequently need community support (odds ratio, 3.32; confidence interval 1.96-5.59) in 5 years, compared to persons without visual impairment during the entire follow-up period. Baseline older age, walking disability, receiving pension, and having 2+ hospital admissions within 12 months were also significantly associated with incident use of support services. Development of bilateral visual impairment in this cohort was associated with greater likelihood of subsequent use of community or informal support services in 5 years, independent of physical comorbidities.

    2016-12-01

    Discoveries over the last three decades have shown that current- and wave-enhanced gravity flows (CWEGFs) are among the significant agents that carry substantial amounts of sediments across low-gradient shelves and thereby they are important elements of sediment source-to-sink. Computational fluid dynamics (CFD) complement the existing field and laboratory experiments in that it offers unprecedented details of participating physical processes. Also, since the state-of-the-art optical and acoustic sensors are limited to measure 50 kg/m3 of suspended sediment concentration, CFD becomes the only means to evaluate the physical processes when the turbid layer is highly concentrated. In this presentation, the roles of wave- and alongshore current-induced turbulent boundary layers are investigated separately on across-shelf fine sediment transport. Turbulence-resolving simulations (Direct Numerical Simulations) that utilize a simplified Eulerian-Eulerian two-phase flow model are conducted. The results show that the sediment carrying capacity of wave boundary layers far exceeds the ones carried by along-shelf currents. The results also show that across-shelf velocity in wall units obeys a logarithmic profile, u+=α ln(z+)+β . However, this logarithmic velocity profile is far apart from the log-law and parameters α and β are dependent on sediment loading and the representative settling velocity of sediments. The key parameters that characterize CWEGFs, such as drag coefficient, Cd, and their variation are also calculated and are found to be close to the ones that are observed in the field experiments. It is also found that for wave boundary layers, drag coefficient increases as the wave orbital velocity increases. Further discussion on the details of the sediment-turbulence interaction is also warranted.

    Full Text Available The impact of the ongoing financial crisis on the availability of finance to small and medium-sized enterprises (SMEs represents an important topic nowadays. The access to finance for SMEs is a major barrier for their growth, especially during severe conditions such as the global financial crisis. Financing the SMEs represents a priority for the most of the multilateral development banks. The aim of the paper is to analyze the activity of European multilateral development banks - European Investment Bank Group and European Bank for Reconstruction and Development - in the support of SMEs. We found that SMEs financing increased during the period 2008-2011 and the international financial institutions took several measures in order to improve the SMEs access to finance.

  8. Would Current International Space Station (ISS) Recycling Life Support Systems Save Mass on a Mars Transit?

    The oxygen and water are recycled on the International Space Station (ISS) to save the cost of launching their mass into orbit. Usually recycling systems are justified by showing that their launch mass would be much lower than the mass of the oxygen or water they produce. Short missions such as Apollo or space shuttle directly provide stored oxygen and water, since the needed total mass of oxygen and water is much less than that of there cycling equipment. Ten year or longer missions such as the ISS or a future moon base easily save mass by recycling while short missions of days or weeks do not. Mars transit and long Mars surface missions have an intermediate duration, typically one to one and a half years. Some of the current ISS recycling systems would save mass if used on a Mars transit but others would not.

  9. Prostate-specific antigen: does the current evidence support its use in prostate cancer screening?

    LENUS (Irish Health Repository)

    Duffy, Michael J

    2012-02-01

    Although widely used, the value of prostate-specific antigen (PSA) in screening asymptomatic men for prostate cancer is controversial. Reasons for the controversy relate to PSA being less than an ideal marker in detecting early prostate cancer, the possibility that screening for prostate cancer may result in the overdetection and thus overtreatment of indolent disease and the lack of clarity as to the definitive or best treatment for men diagnosed with localized prostate cancer. Although the results from some randomized prospective trials suggest that screening with PSA reduces mortality from prostate cancer, the overall benefit was modest. It is thus currently unclear as to whether the modest benefit of reduced mortality outweighs the harms of overdetection and overtreatment. Thus, prior to undergoing screening for prostate cancer, men should be informed of the risks and benefits of early detection. Newly emerging markers that may complement PSA in the early detection of prostate cancer include specific isoforms of PSA and PCA3.

    We conducted a mixed-methods knowledge synthesis to assess the effectiveness of interventions to improve caregivers' involvement in decision making with seniors, and to describe caregivers' experiences of decision making in the absence of interventions. We analyzed forty-nine qualitative, fourteen quantitative, and three mixed-methods studies. The qualitative studies indicated that caregivers had unmet needs for information, discussions of values and needs, and decision support, which led to negative sentiments after decision making. Our results indicate that there have been insufficient quantitative evaluations of interventions to involve caregivers in decision making with seniors and that the evaluations that do exist found few clinically significant effects. Elements of usual care that received positive evaluations were the availability of a decision coach and a supportive decision-making environment. Additional rigorously evaluated interventions are needed to help caregivers be more involved in decision making with seniors.

    Support plate degradation and fouling in nuclear steam generators (SGs) can lead to SG tube corrosion and loss of efficiency. Inspection and monitoring of these conditions can be integrated with preventive maintenance programs, thereby advancing station-life management processes. A prototype pulsed eddy current (PEC) probe, targeting inspection issues associated with SG tubes in SS410 tube support plate structures, has been developed using commercial finite element (FE) software. FE modeling was used to identify appropriate driver and pickup coil configurations for optimum sensitivity to changes in gap and offset for Alloy-800 SG tubes passing through 25 mm thick SS410 support plates. Experimental measurements using a probe that was manufactured based on the modeled configuration, were used to confirm the sensitivity of differential PEC signals to changes in relative position of the tube within the tube support plate holes. Models investigated the effect of shift and tilt of tube with respect to hole centers. Near hole centers and for small shifts, modeled signal amplitudes from the differentially connected coil pairs were observed to change linearly with tube shift. This was in agreement with experimentally measured TEC coil response. The work paves the way for development of a system targeting the inspection and evaluation of support plate structures in steam generators.

    Full Text Available Hayley Uden1, Eva Boesch1, Saravana Kumar1,21Division of Health Sciences, 2International Centre for Allied Health Evidence, University of South Australia, North Terrace, Adelaide, South Australia, AustraliaBackground: Plantar fasciitis is a common condition routinely managed by podiatrists in the community and is widely treated conservatively. Two commonly used treatments for plantar fasciitis are customized functional foot orthoses and corticosteroid injections. While common to clinical practice, the evidence base underpinning these treatment strategies is unknown. Therefore, the aim of this systematic review was to assess the effectiveness and safety of customized functional foot orthoses and corticosteroid injections in the treatment of plantar fasciitis.Methods: A systematic literature search was conducted. Experimental studies, in English, from 1998 to 2010 were accepted for inclusion in this review. The PEDro quality assessment tool and the National Health and Medical Research Council's hierarchy of evidence were used to assess the quality of the included studies.Results: Six randomized controlled trials which met the selection criteria were included in this review. Four reported on customized functional foot orthoses and 2 on corticosteroid injections. Current best available evidence highlights that both customized functional foot orthoses and corticosteroid injections can lead to a decrease in pain associated with plantar fasciitis. Additionally, customized functional foot orthoses may also provide an additional benefit in terms of increased functional ability in patients with plantar fasciitis. Corticosteroid injections may have side effects, especially pain (from the injection.Conclusion: Both customized functional foot orthoses and corticosteroid injections can lead to reduction in pain associated with plantar fasciitis. While customized functional foot orthoses may increase the functional outcomes in patients with plantar fasciitis

  16. Current Evidence Supporting the Link Between Dietary Fatty Acids and Cardiovascular Disease.

    Lack of consensus exists pertaining to the scientific evidence regarding effects of various dietary fatty acids on cardiovascular disease (CVD) risk. The objective of this article is to review current evidence concerning cardiovascular health effects of the main dietary fatty acid types; namely, trans (TFA), saturated (SFA), polyunsaturated (PUFA; n-3 PUFA and n-6 PUFA), and monounsaturated fatty acids (MUFA). Accumulating evidence shows negative health impacts of TFA and SFA; both may increase CVD risk. Policies have been proposed to reduce TFA and SFA consumption to less than 1 and 7 % of energy intake, respectively. Cardiovascular health might be promoted by replacing SFA and TFA with n-6 PUFA, n-3 PUFA, or MUFA; however, the optimal amount of PUFA or MUFA that can be used to replace SFA and TFA has not been defined yet. Evidence suggests of the potential importance of restricting n-6 PUFA up to 10 % of energy and obtaining an n-6/n-3 ratio as close as possible to unity, along with a particular emphasis on consuming adequate amounts of essential fatty acids. The latest evidence shows cardioprotective effects of MUFA-rich diets, especially when MUFA are supplemented with essential fatty acids; namely, docosahexaenoic acid. MUFA has been newly suggested to be involved in regulating fat oxidation, energy metabolism, appetite sensations, weight maintenance, and cholesterol metabolism. These favorable effects might implicate MUFA as the preferable choice to substitute for other fatty acids, especially given the declaration of its safety for up to 20 % of total energy.

    Health care providers are legally obliged to report cases of specified diseases to public health authorities, but existing manual, provider-initiated reporting systems generally result in incomplete, error-prone, and tardy information flow. Automated laboratory-based reports are more likely accurate and timely, but lack clinical information and treatment details. Here, we describe the Electronic Support for Public Health (ESP) application, a robust, automated, secure, portable public health detection and messaging system for cases of notifiable diseases. The ESP application applies disease specific logic to any complete source of electronic medical data in a fully automated process, and supports an optional case management workflow system for case notification control. All relevant clinical, laboratory and demographic details are securely transferred to the local health authority as an HL7 message. The ESP application has operated continuously in production mode since January 2007, applying rigorously validated case identification logic to ambulatory EMR data from more than 600,000 patients.

    Current and future satellite sensors provide remotely sensed quantities from a variety of wavelengths ranging from the visible to the passive microwave, from both geostationary and low-Earth orbits. The NASA Short-term Prediction Research and Transition (SPoRT) Center has a long history of providing multispectral imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA s Terra and Aqua satellites in support of NWS forecast office activities. Products from MODIS have recently been extended to include a broader suite of multispectral imagery similar to those developed by EUMETSAT, based upon the spectral channel s available from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) aboard METEOSAT-9. This broader suite includes products that discriminate between air mass types associated with synoptic-scale features, assists in the identification of dust, and improves upon paired channel difference detection of fog and low cloud events. Similarly, researchers at NOAA/NESDIS and CIRA have developed air mass discrimination capabilities using channels available from the current GOES Sounders. Other applications of multispectral composites include combinations of high and low frequency, horizontal and vertically polarized passive microwave brightness temperatures to discriminate tropical cyclone structures and other synoptic-scale features. Many of these capabilities have been transitioned for evaluation and operational use at NWS Weather Forecast Offices and National Centers through collaborations with SPoRT and CIRA. Future instruments will continue the availability of these products and also expand upon current capabilities. The Advanced Baseline Imager (ABI) on GOES-R will improve the spectral, spatial, and temporal resolution of our current geostationary capabilities, and the recent launch of the Suomi National Polar-Orbiting Partnership (S-NPP) carries instruments such as the Visible Infrared Imager Radiometer Suite (VIIRS), the Cross

    Social support is consistently associated with reduced risk of depression. Few studies have investigated how this relationship may be modified by alcohol use, the effects of which may be particularly relevant in traumatized populations in which rates of alcohol use are known to be high. In 2008 a representative sample of 1622 Jewish and Palestinian citizens in Israel were interviewed by phone at two time points during a period of ongoing terrorism and war threat. Two multivariable mixed effects regression models were estimated to measure the longitudinal association of social support from family and friends on depression symptoms. Three-way interaction terms between social support, alcohol use and time were entered into the models to test for effect modification. Findings indicated that increased family social support was associated with less depression symptomatology (p=<.01); this relationship was modified by alcohol use and time (p=<.01). Social support from friends was also associated with fewer depression symptoms (p=<.01) and this relationship was modified by alcohol use and time as well (p=<.01). Stratified analyses in both models revealed that the effect of social support was stronger for those who drank alcohol regularly than those who did not drink or drank rarely. These findings suggest that social support is a more important protective factor for depression among regular drinkers than among those who do not drink or drink rarely in the context of political violence. Additional research is warranted to determine whether these findings are stable in other populations and settings. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2009-12-16

    This article is part of a series written for people responsible for making decisions about health policies and programmes and for those who support these decision makers. In this article, we address considerations about resource use and costs. The consequences of a policy or programme option for resource use differ from other impacts (both in terms of benefits and harms) in several ways. However, considerations of the consequences of options for resource use are similar to considerations related to other impacts in that policymakers and their staff need to identify important impacts on resource use, acquire and appraise the best available evidence regarding those impacts, and ensure that appropriate monetary values have been applied. We suggest four questions that can be considered when assessing resource use and the cost consequences of an option. These are: 1. What are the most important impacts on resource use? 2. What evidence is there for important impacts on resource use? 3. How confident is it possible to be in the evidence for impacts on resource use? 4. Have the impacts on resource use been valued appropriately in terms of their true costs?

    We investigated the effect of current loading on the degradation behavior of an anode-supported solid oxide fuel cell (SOFC). The cell consisted of LaNi{sub 0.6}Fe{sub 0.4}O{sub 3} (LNF), alumina-doped scandia stabilized zirconia (SASZ), and a Ni-SASZ cermet as the cathode, electrolyte, and anode, respectively. The test was carried out at 1073 K with constant loads of 0.3, 1.0, 1.5, and 2.3 A cm{sup -2}. The degradation rate, defined by the voltage loss during a fixed period (about 1000 h), was faster at higher current densities. From an impedance analysis, the degradation depended mainly on increases in the cathodic resistance, while the anodic and ohmic resistances contributed very little. The cathode microstructures were observed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). (author)

    The purpose of this study was to identify the current status of operations at community general support centers which provide coordination for elderly care and the correlation of personal traits, work environment and the occupational stress of the staff. Subjects of the study were 251 staff members of community general support centers. The current status of operations at the community general support centers and the personal traits, work environment, effort-remuneration imbalance model (ERI) and general health questionnaire (GHQ) were surveyed. The initial analysis involved a comparison by a chi-square test on: The effort-remuneration ratio (E/R ratio) of personal traits and work environment, risk of over-commitment (OC), and GHQ score. To explore the correlation between the E/R ratio of the three GHQ groups (low, middle and high score groups) and the OC value, one-way analysis of variance was performed. Out of the four basic functions of the community general support centers, 22.0% of the respondents noted that "establishment of a regional, comprehensive/multi-tiered service network" was functioning, and 50.4% of respondents noted that "comprehensive and continuous care management" was functioning. The average effort score was 15.5 +/- 5.3, approximately double the average value of preceding studies. Significant differences found in GHQ scores were related to working hours (pworking hours of 50 h or more" (OR: 10.38, 95% CI: 2.52-42.70), "Unstable employment" (OR: 2.75, 95% CI: 1.22-6.21) and "Anxiety related to task content" (OR: 17.04, 95% CI: 3.57-81.24). Items observed to have significant correlation with OC value risk factors were: "Weekly working hours of 50 h or more" (OR: 8.04, 95% CI: 1.99-32.41) and "Anxiety related to task content" (OR: 4.60, 95% CI: 2.04-10.37). We conclude that the basic functions of the community general support centers are not presently very functional. The stress levels of the community general support center staff are high and

    Nurses of ethnically diverse backgrounds are essential in providing multicultural populations in western societies with culturally and linguistically competent health care. However, many nurses from non-English speaking backgrounds (NESB) are at high risk of failure in university programs particularly during clinical placements. Few studies investigate the clinical experiences of students from NESB and strategies to support their learning. This study describes perceptions of fifteen undergraduate nursing students from NESB about their first clinical placement in an Australian university program and the effect of a language support program on their oral clinical communication skills. Three categories arose: *Wanting to belong but feeling excluded; *Wanting to learn how to...; and *You find yourself. While many students find clinical placement challenging, it appeared difficult for students in this study as language and cultural adjustments required some modification of their usual ways of thinking and communicating, often without coping strategies available to other students.

    Dynamic contrast-enhanced computed tomography (DCE-CT) assesses the vascular support of tumours through analysis of temporal changes in attenuation in blood vessels and tissues during a rapid series of images acquired with intravenous administration of iodinated contrast material. Commercial software for DCE-CT analysis allows pixel-by-pixel calculation of a range of validated physiological parameters and depiction as parametric maps. Clinical studies support the use of DCE-CT parameters as surrogates for physiological and molecular processes underlying tumour angiogenesis. DCE-CT has been used to provide biomarkers of drug action in early phase trials for the treatment of a range of cancers. DCE-CT can be appended to current imaging assessments of tumour response with the benefits of wide availability and low cost. This paper sets out guidelines for the use of DCE-CT in assessing tumour vascular support that were developed using a Delphi process. Recommendations encompass CT system requirements and quality assurance, radiation dosimetry, patient preparation, administration of contrast material, CT acquisition parameters, terminology and units, data processing and reporting. DCE-CT has reached technical maturity for use in therapeutic trials in oncology. The development of these consensus guidelines may promote broader application of DCE-CT for the evaluation of tumour vascularity. (orig.)

    Full Text Available Abstract Background Organizations have been established in many countries and internationally to support the use of research evidence by producing clinical practice guidelines, undertaking health technology assessments, and/or directly supporting the use of research evidence in developing health policy on an international, national, and state or provincial level. Learning from these organizations can reduce the need to 'reinvent the wheel' and inform decisions about how best to organize support for such organizations, particularly in low- and middle-income countries (LMICs. Methods We undertook a multi-method study in three phases – a survey, interviews, and case descriptions that drew on site visits – and in each of the second and third phases we focused on a purposive sample of those involved in the previous phase. We used the seven main recommendations that emerged from the advice offered in the interviews to organize much of the synthesis of findings across phases and methods. We used a constant comparative method to identify themes from across phases and methods. Results Seven recommendations emerged for those involved in establishing or leading organizations that support the use of research evidence in developing health policy: 1 collaborate with other organizations; 2 establish strong links with policymakers and involve stakeholders in the work; 3 be independent and manage conflicts of interest among those involved in the work; 4 build capacity among those working in the organization; 5 use good methods and be transparent in the work; 6 start small, have a clear audience and scope, and address important questions; and 7 be attentive to implementation considerations, even if implementation is not a remit. Four recommendations emerged for the World Health Organization (WHO and other international organizations and networks: 1 support collaborations among organizations; 2 support local adaptation efforts; 3 mobilize support; and 4 create

    Sepsis is a systemic response associated with very high mortality. Early initiation of the correct antimicrobial therapy remains a cornerstone in the treatment of sepsis. Currently, a new microbiological test is under development, which aims to detect major, prevalent pathogens in positive blood cultures within an hour. Concurrently, a tablet-based data entry and reporting system will be developed to facilitate the workflow of the test. This study investigated the system requirements for the tablet-based data entry and reporting system in order to support the clinical workflow. By observing the workflow of the blood culture analysis and through interviews with medical laboratory technicians, four main system requirements were identified. The system requirements are; the ability to receive and send data to the laboratory information system, support for the use of barcodes, the ability to access a browser based instruction system, and communication of results between medical laboratory technicians and physicians. These system requirements will be used as a basis in the future development of the tablet-based data entry and reporting system.

    Solid waste management is a complex domain involving the interaction of several dimensions; thus, its analysis and control impose continuous challenges for decision makers. In this context, multi-criteria decision-making models have become important and convenient supporting tools for solid waste management because they can handle problems involving multiple dimensions and conflicting criteria. However, the selection of the multi-criteria decision-making method is a hard task since there are several multi-criteria decision-making approaches, each one with a large number of variants whose applicability depends on information availability and the aim of the study. Therefore, to support researchers and decision makers, the objectives of this article are to present a literature review of multi-criteria decision-making applications used in solid waste management, offer a critical assessment of the current practices, and provide suggestions for future works. A brief review of fundamental concepts on this topic is first provided, followed by the analysis of 260 articles related to the application of multi-criteria decision making in solid waste management. These studies were investigated in terms of the methodology, including specific steps such as normalisation, weighting, and sensitivity analysis. In addition, information related to waste type, the study objective, and aspects considered was recorded. From the articles analysed it is noted that studies using multi-criteria decision making in solid waste management are predominantly addressed to problems related to municipal solid waste involving facility location or management strategy.

    Full Text Available BackgroundHigher cancer morbidity and mortality rates for the Indigenous population comparedto the overall Australian population has underlined the critical need to improve accessfor Aboriginal people to cancer treatment services. This paper describes anIndigenous Women’s Cancer Support Group (IWCSG established to supportIndigenous people with cancer and their carers/relatives and to facilitate Aboriginalaccess to cancer screening and treatment. Preliminary findings from an evaluation ofthe group are presented.MethodsThe study employed qualitative research methods to describe IWCSG operations andinvestigate the group’s effectiveness. It included one-on-one interviews with 11Geraldton-based health service providers, the IWCSG coordinator, and 10 womenwho have been linked to IWCSG support, as well as observation of group meetings.ResultsDescriptive outcomes relate to group operations, group effectiveness, group benefitsand future development of the group. A cultural strength of IWCSG is its ability tooperate confidentially behind the scenes, providing emotional support and practicalhelp directly to Indigenous people concerned about privacy and shame issues. Theimportant cultural role IWCSG plays in overcoming communication and othercultural barriers to accessing cancer treatment was unanimously recognised by healthservice providers. Aboriginal women supported by IWCSG spoke about an increasedsense of safety, trust and support in accessing and navigating mainstream cancerservices. A critical issue emerging from the research is the need for further development of effective collaborative working relationships between IWCSGmembers and health service providers.ConclusionsThe IWCSG has the potential to inform an effective model for facilitating Indigenousaccess both to cancer treatment and to mainstream treatment for a variety of healthproblems. Future research is required to explore the applicability of Indigenoussupport groups and to focus on the

    We examined the relationship between two forms of ethnic discrimination-interpersonal and institutional-and smoking outcomes among Arab men in Israel, and whether social support buffered these associations. We used cross-sectional data of adult Arab men, current or former smokers (n = 954). Mixed-effects regression models estimated the association between discrimination and smoking status, and nicotine dependence among current smokers. Interpersonal discrimination was associated with higher likelihood of being a current smoker compared to a former smoker, whereas institutional group discrimination was not. Social support moderated the ethnic discrimination-nicotine dependence link. Among men with low social support, greater interpersonal discrimination was associated with greater nicotine dependence. Similarly, among smokers with high institutional group discrimination, those with high social support reported lower nicotine dependence compared to those with low social support. Ethnic discrimination should be considered in efforts to improve smoking outcomes among Arab male smokers in Israel.

    Background Chronic obstructive pulmonary disease (COPD) is a serious long-term lung disease in which the airflow from the lungs is progressively reduced. By 2030, COPD will become the third cause of mortality and seventh cause of morbidity worldwide. With advances in technology and mobile communications, significant progress in the mobile health (mHealth) sector has been recently observed. Mobile phones with app capabilities (smartphones) are now considered as potential media for the self-management of certain types of diseases such as asthma, cancer, COPD, or cardiovascular diseases. While many mobile apps for patients with COPD are currently found on the market, there is little published material on the effectiveness of most of them, their features, and their adoption in health care settings. Objectives The aim of this study was to search the literature for current systems related to COPD and identify any missing links and studies that were carried out to evaluate the effectiveness of COPD mobile apps. In addition, we reviewed existing mHealth apps from different stores in order to identify features that can be considered in the initial design of a COPD support tool to improve health care services and patient outcomes. Methods In total, 206 articles related to COPD management systems were identified from different databases. Irrelevant materials and duplicates were excluded. Of those, 38 articles were reviewed to extract important features. We identified 214 apps from online stores. Following exclusion of irrelevant apps, 48 were selected and 20 of them were downloaded to review some of their common features. Results Our review found that out of the 20 apps downloaded, 13 (65%, 13/20) had an education section, 5 (25%, 5/20) consisted of medication and guidelines, 6 (30%, 6/20) included a calendar or diary and other features such as reminders or symptom tracking. There was little published material on the effectiveness of the identified COPD apps. Features such as

    Full Text Available The peculiarities in the functioning of the current system of inter-budget relations in Ukraine from the perspective of its impact on the regional development have been disclosed. The instruments of implementing fiscal equalization are analyzed, the functioning structure of inter-budget transfers in Ukraine is presented, its characteristics are given. The study demonstrates that the domestic financial equalization system is unable to perform its functions. The conducted analysis of the dynamics and structure of inter-budget transfers made it possible to identify a number of shortcomings in the sphere of inter-budget relations: the excessive centralization of financial resources of regions and their transfer dependence; the imbalances and low revenue capacity of local budgets; the imperfect mechanisms for calculating transfers and terms of transferring, etc. It is noted that in the process of implementing the budgetary policy of the regions, it is advisable to pay more attention to forms of budget support and methods of budgetary regulation.

    Full Text Available The purpose of this paper is to examine how ICT development is progressing and what kind of political and social effects have been occurring (or could occur in the near future in Middle Eastern Arabic countries. To examine this theme, this paper will adopt the Syrian Arab Republic as a case. To understand the Syrian government's policy toward the ICT development, it is necessary to examine the domestic political situation, since they are closely related. Under the Bashar Al- Asad's regime, we can confirm several reasons why they have to move forward on their ICT development policy and why it has become a crucial issue, which they cannot evade, as they had done under the previous regime, Hafez Al- Asad's regime. The situation that the Syrian government is facing right now is known by the term, "Dictator's Dilemma". This paper tries to provide bases in order to examine and explore this dilemma in Syria. Also, when we examine ICT development in Syria, it is important to consider the ICT support policies, which are mainly conducted by OECD countries and international organizations and stem from the issue of "Digital Divide". This is why international assistances could have great effect on ICT development in Syria. As a provisional conclusion of this paper, I will summarize how we can understand the current situation of ICT development in Syria, and I will also comment on the future prospect of the dilemma that the Syrian government is facing at the present time.

    Initiatives to support the sustainable development of the nanotechnology sector have led to rapid growth in research on the environmental fate, hazards and risk of engineered nanoparticles (ENP). As the field has matured over the last 10 years, a detailed picture of the best methods to track potential forms of exposure, their uptake routes and best methods to identify and track internal fate and distributions following assimilation into organisms has begun to emerge. Here we summarise the current state of the field, focussing particularly on metal and metal oxide ENPs. Studies to date have shown that ENPs undergo a range of physical and chemical transformations in the environment to the extent that exposures to pristine well dispersed materials will occur only rarely in nature. Methods to track assimilation and internal distributions must, therefore, be capable of detecting these modified forms. The uptake mechanisms involved in ENP assimilation may include a range of trans-cellular trafficking and distribution pathways, which can be followed by passage to intracellular compartments. To trace toxicokinetics and distributions, analytical and imaging approaches are available to determine rates, states and forms. When used hierarchically, these tools can map ENP distributions to specific target organs, cell types and organelles, such as endosomes, caveolae and lysosomes and assess speciation states. The first decade of ENP ecotoxicology research, thus, points to an emerging paradigm where exposure is to transformed materials transported into tissues and cells via passive and active pathways within which they can be assimilated and therein identified using a tiered analytical and imaging approach.

    Full Text Available The prevalence of e-cigarette use is increasing, yet few studies have focused on its use in racial/ethnic minority populations. We examined associations between race/ethnicity and e-cigarette use, plans to continue using e-cigarettes, and reasons for use among current/former smokers. Participants (285 in total; 29% non-Hispanic White, 42% African American/Black, and 29% Hispanic were recruited between June and November 2014. Telephone-administered surveys assessed demographics, cigarette smoking, e-cigarette use, plans to continue using, and reasons for use. Analyses of covariance (ANCOVAs and multivariable logistic regressions were conducted. African Americans/Blacks were significantly less likely to report ever-use compared to Whites and Hispanics (50% vs. 71% and 71%, respectively; p < 0.001. However, African American/Black ever users were more likely to report plans to continue using e-cigarettes compared to Whites and Hispanics (72% vs. 53% and 47%, respectively, p = 0.01. African American/Black participants were more likely to use e-cigarettes as a cessation aid compared to both Whites (p = 0.03 and Hispanics (p = 0.48. White participants were more likely to use e-cigarettes to save money compared to Hispanics (p = 0.02. In conclusion, racial/ethnic differences in e-cigarette use, intentions, and reasons for use emerged in our study. African American ever users may be particularly vulnerable to maintaining their use, particularly to try to quit smoking. These findings have implications for cigarette smoking and e-cigarette dual use, continued e-cigarette use, and potentially for smoking-related disparities.

    One of the potential solutions in social and environmental sustainability in municipal solid waste management (MSW) in Metro Manila is to combine community-based recycling and sound landfill management strategies. The marriage of the two puts importance on recycling as a source of livelihood while proper landfill management aims to improve the aesthetic and environmental quality of disposal facilities in urban areas. To do this, a social mapping of wastepickers, junkshops and local recycling practices needs to be undertaken and at the same time assess strategies of the national and local governments vis-à-vis existing laws on municipal solid waste. The case of Payatas controlled disposal facility was taken as a pilot study because it represents the general condition of disposal sites in Metro Manila and the social landscape that it currently has. In addition, a waste-to-energy (WTE) project has been established in Payatas to produce electricity from methane gas. Preliminary interviews with wastepickers show that development interventions in disposal sites such as WTE pose no opposition from host communities for as long as alternative livelihood opportunities are provided. Regulating the flow of wastepickers into the landfill has advantages like improved income and security. Felt needs were also articulated like provision of financial support or capital for junkshop operation and skills training. Overall, a smooth relationship between the local government and community associations pays well in a transitioning landfill management scheme such as Payatas.

    This study described how parents perceived their own sleep, and their infants', during neonatal intensive care unit (NICU) admission and after discharge. It also explored the infants' sleeping location at home. The study was conducted in the NICUs of two Swedish university hospitals. The parents of 86 infants - 86 mothers and 84 fathers - answered questionnaires during their infants' hospital stay, at discharge and at the infants' corrected ages of two, six and 12 months. The parents' own sleep was explored with the Insomnia Severity Index. Mothers reported more severe insomnia than fathers during their infants' hospitalisation, and these higher insomnia severity scores were associated with more severe infant sleep problems at discharge (p = 0.027) and at two months (p = 0.006) and 12 months (p = 0.002) of corrected age. During the study period, 4%-10% of the parents reported severe or very severe infant sleeping problems. The bed-sharing rate was 75% after discharge and about 60% at the corrected age of 12 months. Maternal insomnia during an infant's hospital stay was associated with later perceptions of sleep problems in their children. Parents need support to find solutions for optimal sleep without seeing their child's sleeping patterns as a problem. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Here a dual approach has been adopted to study the effect of both synthesis as well as annealing temperature on the electron field emission property of differently synthesized carbon nanotubes (CNTs) that include solid state chemical reaction as well as chemical vapour deposition (CVD). Experimental findings were supported by theoretical simulation. All the samples were characterized by X-ray diffraction (XRD), Fourier transformed infrared spectroscopy, Raman spectroscopy, field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). XRD as well as TEM study confirms the amorphous nature (aCNTs) of the samples for both the synthesis techniques which is attributed to lower synthesis temperature. Prominent morphological differences of these two types of aCNTs are clearly observed from both FESEM and TEM images. It is found that electron field emission characteristics of aCNTs synthesized by CVD shows better field emission properties as compared to aCNTs synthesized by solid state reaction. Finite element based simulation shows that temperature has prominent effect on morphology, screening effect or degree of graphitization that leads to improved field emission characteristics for the CVD synthesized aCNTs.

    Background The adolescent and early adult years are periods of peak prevalence and incidence for most mental disorders. Despite the rapid expansion of Web-based mental health care, and increasing evidence of its effectiveness, there is little research investigating the characteristics of young people who access Web-based mental health care. headspace, Australia’s national youth mental health foundation, is ideally placed to explore differences between young people who seek Web-based mental health care and in-person mental health care as it offers both service modes for young people, and collects corresponding data from each service type. Objective The objective of this study was to provide a comprehensive profile of young people seeking Web-based mental health care through eheadspace (the headspace Web-based counseling platform), and to compare this with the profile of those accessing help in-person through a headspace center. Methods Demographic and clinical presentation data were collected from all eheadspace clients aged 12 to 25 years (the headspace target age range) who received their first counseling session between November 1, 2014 and April 30, 2015 via online chat or email (n=3414). These Web-based clients were compared with all headspace clients aged 12 to 25 who received their first center-based counseling service between October 1, 2014 and March 31, 2015 (n=20,015). Results More eheadspace than headspace center clients were female (78.1% compared with 59.1%), and they tended to be older. A higher percentage of eheadspace clients presented with high or very high levels of psychological distress (86.6% compared with 73.2%), but they were at an earlier stage of illness on other indicators of clinical presentation compared with center clients. Conclusions The findings of this study suggest that eheadspace is reaching a unique client group who may not otherwise seek help or who might wait longer before seeking help if in-person mental health support was

    A novel transient rotor current control scheme is proposed in this paper for a doubly-fed induction generator (DFIG) equipped with a superconducting magnetic energy storage (SMES) device to enhance its transient voltage and frequency support capacity during grid faults. The SMES connected to the DC-link capacitor of the DFIG is controlled to regulate the transient dc-link voltage so that the whole capacity of the grid side converter (GSC) is dedicated to injecting reactive power to the grid for the transient voltage support. However, the rotor-side converter (RSC) has different control tasks for different periods of the grid fault. Firstly, for Period I, the RSC injects the demagnetizing current to ensure the controllability of the rotor voltage. Then, since the dc stator flux degenerates rapidly in Period II, the required demagnetizing current is low in Period II and the RSC uses the spare capacity to additionally generate the reactive (priority) and active current so that the transient voltage capability is corroborated and the DFIG also positively responds to the system frequency dynamic at the earliest time. Finally, a small amount of demagnetizing current is provided after the fault clearance. Most of the RSC capacity is used to inject the active current to further support the frequency recovery of the system. Simulations are carried out on a simple power system with a wind farm. Comparisons with other commonly used control methods are performed to validate the proposed control method.

    Objective: An important minority of military personnel will experience mental health problems after overseas deployments. Our study sought to describe the prevalence and correlates of postdeployment mental health problems in Canadian Forces personnel. Method: Subjects were 16 193 personnel who completed postdeployment screening after return from deployment in support of the mission in Afghanistan. Screening involved a detailed questionnaire and a 40-minute, semi-structured interview with a mental health clinician. Mental health problems were assessed using the Patient Health Questionnaire and the Posttraumatic Stress Disorder Checklist—Civilian Version. Logistic regression was used to explore independent risk factors for 1 or more of 6 postdeployment mental health problems. Results: Symptoms of 1 or more of 6 mental health problems were seen in 10.2% of people screened; the most prevalent symptoms were those of major depressive disorder (3.2%), minor depression (3.3%), and posttraumatic stress disorder (2.8%). The strongest risk factors for postdeployment mental health problems were past mental health care (adjusted odds ratio [AOR] 2.89) and heavy combat exposure (AOR 2.57 for third tertile, compared with first tertile). These risk groups might be targeted in prevention and control efforts. In contrast to findings from elsewhere, Reservist status, deployment duration, and number of previous deployments had no relation with mental health problems. Conclusions: An important minority of personnel will disclose symptoms of mental health problems during postdeployment screening. Differences in risk factors seen in different nations highlight the need for caution in applying the results of research in one population to another. PMID:25007406

    Highlights: • Pathway and efficiency are linked to the current-electrode–electrolyte interaction. • Unlike BDD, IrO{sub 2} route was independent of current but dependent on the electrolyte. • IrO{sub 2}/SO{sub 4}{sup 2−} and IrO{sub 2}/Cl{sup −} routes were via IrO{sub 3} and chlorine species, respectively. • BDD/SO{sub 4}{sup 2−} and IrO{sub 2}/Cl{sup −} systems were favored at low and high currents, respectively. - Abstract: Taking crystal violet (CV) dye as pollutant model, the electrode, electrolyte and current density (i) relationship for electro-degrading organic molecules is discussed. Boron-doped diamond (BDD) or Iridium dioxide (IrO{sub 2}) used as anode materials were tested with Na{sub 2}SO{sub 4} or NaCl as electrolytes. CV degradation and generated oxidants showed that degradation pathways and efficiency are strongly linked to the current density-electrode–electrolyte interaction. With BDD, the degradation pathway depends on i: If i < the limiting current density (i{sub lim}), CV is mainly degraded by ·OH radicals, whereas if i > i{sub lim}, generated oxidants play a major role in the CV elimination. When IrO{sub 2} was used, CV removal was not dependent on i, but on the electrolyte. Pollutant degradation in Na{sub 2}SO{sub 4} on IrO{sub 2} seems to occur via IrO{sub 3}; however, in the presence of NaCl, degradation was dependent on the chlorinated oxidative species generated. In terms of efficiency, the Na{sub 2}SO{sub 4} electrolyte showed better results than NaCl when BDD anodes were employed. On the contrary, NaCl was superior when combined with IrO{sub 2}. Thus, the IrO{sub 2}/Cl{sup −} and BDD/SO{sub 4}{sup 2−} systems were better at removing the pollutant, being the former the most effective. On the other hand, pollutant degradation with the BDD/SO{sub 4}{sup 2−} and IrO{sub 2}/Cl{sup −} systems is favored at low and high current densities, respectively.

    Full Text Available In this contribution we present for the first time a continuous process for the production of highly active Pt catalysts supported by carbon nanotubes by use of an electrically heated tubular reactor. The synthesized catalysts show a high degree of dispersion and narrow distributions of cluster sizes. In comparison to catalysts synthesized by the conventional oil-bath method a significantly higher electrocatalytic activity was reached, which can be attributed to the higher metal loading and smaller and more uniformly distributed Pt particles on the carbon support. Our approach introduces a simple, time-saving and cost-efficient method for fuel cell catalyst preparation in a flow reactor which could be used at a large scale.

    A co-extrusion technique was employed to fabricate a dual layer NiO/NiO-YSZ hollow fibre precursor which was then co-sintered at 1400C and reduced at 700C to form, respectively, a meshed porous inner Ni current collector and outer Ni-YSZ anode layers for SOFC applications. Achieved morphology consisted of short finger-like voids originating from the inner bore of the hollow fibre, and a sponge-like structure filling most of the Ni-YSZ anode layer, which is considered to be suitable macrostructure for anode SOFC system. The electrical conductivity of the meshed porous inner Ni layer was measured to be 77.5 x 10{sup 5} S m{sup -1}. This result is significantly higher than previous reported results on single layer Ni-YSZ hollow fibres, which besides performing a catalyst function for the oxidation reaction also act as a current collector. These results highlight the advantages of this dual-layer hollow fibre design especially in developing a new and highly efficient way in current collection for micro-tubular SOFC. (author)

    Full Text Available Background: Promoting physical activity (PA via primary care exercise referral schemes (ERS is common but there is no rigorous evidence for long term changes in PA (Pavey et al, 2011 among those with chronic conditions. From July 2015, for 15 months, the e-coachER trial began to recruit 1400 patients (in SW England, Birmingham and Glasgow with one or more chronic conditions including diabetes, obesity, hypertension, osteoarthritis, or depression, who are eligible and about to attend an ERS. The two-arm parallel RCT is powered to determine if the addition of a web-based, interactive, theory-driven and evidence-based support system called e-coachER (hosted on the ‘LifeGuide’ platform will result in at least 10% more patients who do 150 mins or more per week of accelerometer assessed moderate or vigorous physical activity (MVPA at 12 months. Recruitment into the trial is within primary care, using both mail-merged patient invitations and opportunistic GP invitations (and exercise referrals. Within the trial, after participants are screened, provide consent and complete baseline assessments, they are randomised to receive usual ERS at each site or usual ERS plus a mailed Welcome Pack with registration details to access e-coachER on-line. Inclusion criteria for entering the trial are: (1 Aged 16-74 years; (2 with one or more of the following: obesity (BMI 30-35, hypertension (SBP 140-179 or DBP 90-109, type 2 diabetes, lower limb osteoarthritis, recent history of treatment for depression; (3 Participants who are in the two lowest (of four groups using the GP Physical Activity Questionnaire; (4 have an e-mail address and access to the internet; (5 Eligible for an ERS.

    The concept of student support within distance education is particularly diffuse. A learner- or student-centered vision of education considers the needs of individual learners. Another view confines the concept to an add-on, complementary or compensatory approach. One way to consider the question of what student support is necessary is to appraise…

  12. Dietary and nutritional treatments for attention-deficit/hyperactivity disorder: current research support and recommendations for practitioners.

    Hurt, Elizabeth A; Arnold, L Eugene; Lofthouse, Nicholas

    2011-10-01

    Evidence for dietary/nutritional treatments of attention-deficit/hyperactivity disorder (ADHD) varies widely, from double-blind, placebo-controlled trials to anecdotal. In guiding patients, clinicians can apply the SECS versus RUDE rule: treatments that are Safe, Easy, Cheap, and Sensible (SECS) require less evidence than those that are Risky, Unrealistic, Difficult, or Expensive (RUDE). Two nutritional treatments appear worth general consideration: Recommended Daily Allowance/Reference Daily Intake multivitamin/mineral supplements as a pediatric health intervention not specific to ADHD and essential fatty acids, especially a mix of eicosapentaenoic acid, docosahexaenoic acid, and γ-linolenic acid as an ADHD-specific intervention. Controlled studies support the elimination of artificial food dyes to reduce ADHD symptoms, but this treatment may be more applicable to the general pediatric population than to children with diagnosed ADHD. Mineral supplementation is indicated for those with documented deficiencies but is not supported for others with ADHD. Carnitine may have a role for inattention, but the evidence is limited. Dimethylaminoethanol probably has a small effect. Herbs, although "natural," are actually crude drugs, which along with homeopathic treatments have little evidence of efficacy. Consequences of delayed proven treatments need consideration in the risk-benefit assessment of dietary/nutritional treatments.

    Taking crystal violet (CV) dye as pollutant model, the electrode, electrolyte and current density (i) relationship for electro-degrading organic molecules is discussed. Boron-doped diamond (BDD) or Iridium dioxide (IrO2) used as anode materials were tested with Na2SO4 or NaCl as electrolytes. CV degradation and generated oxidants showed that degradation pathways and efficiency are strongly linked to the current density-electrode-electrolyte interaction. With BDD, the degradation pathway depends on i: If idegraded by OH radicals, whereas if i>i(lim), generated oxidants play a major role in the CV elimination. When IrO2 was used, CV removal was not dependent on i, but on the electrolyte. Pollutant degradation in Na2SO4 on IrO2 seems to occur via IrO3; however, in the presence of NaCl, degradation was dependent on the chlorinated oxidative species generated. In terms of efficiency, the Na2SO4 electrolyte showed better results than NaCl when BDD anodes were employed. On the contrary, NaCl was superior when combined with IrO2. Thus, the IrO2/Cl(-) and BDD/SO4(2-) systems were better at removing the pollutant, being the former the most effective. On the other hand, pollutant degradation with the BDD/SO4(2-) and IrO2/Cl(-) systems is favored at low and high current densities, respectively. Copyright © 2014 Elsevier B.V. All rights reserved.

    2015-02-15

    The prevalence of small renal masses (SRM) has risen, paralleling the increased usage of cross-sectional imaging. A large proportion of these SRMs are not malignant, and do not require invasive treatment such as nephrectomy. Therefore, differentation between early renal cell carcinoma (RCC) and benign SRM is critical to achieve proper management. This article reviews the radiological features of benign SRMs, with focus on two of the most common benign entities, angiomyolipoma and oncocytoma, in terms of their common imaging findings and differential features from RCC. Furthermore, the role of percutaneous biopsy is discussed as imaging is yet imperfect, therefore necessitating biopsy in certain circumstances to confirm the benignity of SRMs.

    English stakeholder collaboration has resulted in a new quality assurance process for non-medical health and social care placement providers and higher education institutions. This study aimed to discover the impact on student support that taking part in a pilot had on participating placement areas. Using a questionnaire survey with longitudinal follow-up one year later, we found that placement staff valued the opportunity to review and improve student support practices. This was still in evidence a year later where the pilot was described as giving the opportunity to provide evidence of aspects of student support practice; communicating and changing or developing aspects of that practice. Benefits accrued from interdisciplinary working in sharing and collaborating with other professions and organisations. Such activity could enhance clinical support staff activities and facilitate strategic partnerships between placement providers and higher education institutions.

  19. A Comment on “Management for Mountain Pine Beetle Outbreak Suppression: Does Relevant Science Support Current Policy?”

    Directory of Open Access Journals (Sweden)

    Christopher J. Fettig

    2014-04-01

    Full Text Available There are two general approaches for reducing the negative impacts of mountain pine beetle, Dendroctonus ponderosae Hopkins, on forests. Direct control involves short-term tactics designed to address current infestations by manipulating mountain pine beetle populations, and includes the use of fire, insecticides, semiochemicals, sanitation harvests, or a combination of these treatments. Indirect control is preventive, and designed to reduce the probability and severity of future infestations within treated areas by manipulating stand, forest and/or landscape conditions by reducing the number of susceptible host trees through thinning, prescribed burning, and/or alterations of age classes and species composition. We emphasize that “outbreak suppression” is not the intent or objective of management strategies implemented for mountain pine beetle in the western United States, and that the use of clear, descriptive language is important when assessing the merits of various treatment strategies.

    2016-01-01

    Over the last decade, the use of electrosurgical devices has become commonplace across all surgical specialities. The current market is large enough to warrant a comparative review of each device. This has even more impetus given the budgetary constraints of NHS organisations. This review aims to compare the benefits and drawbacks of the most popular electrosurgical devices, whilst conducting a critical review of the literature. Structured searches using databases Medline and EMBASE were conducted. The search was restricted to English language papers only. Due to the abundance of literature, this review will focus on common general surgical procedures alone. Despite a plethora of available devices, individual preference still dictates use. Conventional diathermy may always have its place, but may see a decline in use if costs improve. Newer devices have shown comparable precision and added advantages.

    Some waterpipe smokers exhibit nicotine dependent behaviors such as increased use over time and inability to quit, placing them at high risk of adverse health outcomes. This study examines the determinants of dependence by measuring frequency of use among current waterpipe smokers using a large national U.S. Data were drawn from four waves (Spring/Fall 2009 and Spring/Fall 2010) of the American College Health Association-National College Health Assessment datasets. The sample was restricted to students who smoked a waterpipe at least once in the past 30 days (N=19,323). Ordered logistic regression modeled the factors associated with higher frequency of waterpipe smoking. Among current waterpipe smokers, 6% used a waterpipe daily or almost daily (20-29 days). Daily cigarette smokers were at higher odds of smoking a waterpipe at higher frequencies compared with non-smokers of cigarettes (OR=1.81; 95% CI=1.61-2.04). There was a strong association between daily cigar smoking and higher frequency of waterpipe smoking (OR=7.77; 95% CI=5.49-11.02). Similarly, students who used marijuana had higher odds of smoking a waterpipe at higher frequencies (OR=1.57; 95% CI=1.37-1.81). Daily consumers of other addictive substances are at a higher risk of intensive waterpipe smoking and thus higher risk of waterpipe dependence. Intervention programs must incorporate methods to reduce waterpipe dependence and subsequently prevent its deleterious health effects. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  2. The epidemiology of dengue infection: Harnessing past experience and current knowledge to support implementation of future control strategies

    Full Text Available Dengue is the most important mosquito-borne viral infection of humans. Although outbreaks of disease which are now recognized as clinically consistent with dengue have been reported for centuries, it was not until half a century ago that laboratory identification of dengue viruses as the etiological agent of febrile illness was achieved. This debilitating and sometimes fatal disease is widely distributed in >125 countries in tropical and subtropical zones of the world. Asia, South America and the Pacific Islands are hyper-epidemic regions while currently there is less prevalence in Europe, North America and Australia. The estimated global incidence ranges between 200 and 400 million clinical cases per year. While some areas of past epidemics are now considered to be under control, recent decades have witnessed an epidemic rise in dengue worldwide. Major factors facilitating expansion include climate change and increase in urbanization and international travel. Concurrently, the non-availability of an efficacious antiviral drug or vaccine and a lack of effective vector control strategies collectively make dengue a serious public health concern. Thus, it is of paramount importance to analyze the history of the spread of infection and to gain a deeper understanding of patterns of transmission in order to anticipate epidemiological trends more accurately, thereby enabling better preparedness for future outbreaks.

    Full Text Available Abstract Background Osteopenia and rickets are common among extremely low birth weight infants (ELBW, Methods We evaluated all ELBW infants admitted to Texas Children's Hospital NICU in 2006 and 2007. Of 211 admissions, we excluded 98 patients who were admitted at >30 days of age or did not survive/stay for >6 weeks. Bone radiographs obtained in 32 infants were reviewed by a radiologist masked to laboratory values. Results In this cohort of 113 infants, P-APA was found to have a significant inverse relationship with BW, gestational age and serum phosphorus. In paired comparisons, P-APA of infants Conclusion Elevation of P-APA >600 IU/L was very common in ELBW infants. BW was significantly inversely related to both P-APA and radiologic rickets. No single value of P-APA was related to radiological findings of rickets. Given the very high risk of osteopenia and rickets among ELBW infants, we recommend consideration of early screening and early mineral supplementation, especially among infants

    Purpose A cross-sectional survey to evaluate the current management of wet age-related macular degeneration (wAMD) and to identify barriers to treatment from a patient and caregiver perspective. Methods An ophthalmologist-devised questionnaire was given to a global cohort of patients who were receiving (or had previously received) antivascular endothelial growth factor injections and to caregivers (paid and unpaid) to evaluate the impact of wAMD on their lives. Results Responders included 910 patients and 890 caregivers; wAMD was diagnosed in both eyes in 45% of patients, and 64% had been receiving injections for > 1 year. Many caregivers were a child/grandchild (47%) or partner (23%) of the patient; only 7% were professional caregivers. Most (73%) patients visited a health care professional within 1 month of experiencing vision changes and 54% began treatment immediately. Most patients and caregivers reported a number of obstacles in managing wAMD, including the treatment itself (35% and 39%, respectively). Sixteen percent of patients also missed a clinic visit. Conclusion Most patients seek medical assistance promptly for a change in vision; however, about a quarter of them do not. This highlights a lack of awareness surrounding eye health and the impact of a delayed diagnosis. Most patients and caregivers identified a number of obstacles in managing wAMD. PMID:26664038

    Antifungal susceptibilities of non-Aspergillus filamentous fungal pathogens cannot always be inferred from their identification. Here we determined, using the Sensititre(®) YeastOne(®) YO10 panel, the in vitro activities of nine antifungal agents against 52 clinical isolates of emergent non-Aspergillus moulds representing 17 fungal groups in Australia. Isolates comprised Mucorales (n = 14), Scedosporium/Lomentospora spp. (n = 18) and a range of hyaline hyphomycetes (n = 9) and other dematiaceous fungi (n = 11). Excluding Verruconis gallopava, echinocandins demonstrated poor activity (MICs generally >8 mg/L) against these moulds. Lomentospora prolificans (n = 4) and Fusarium spp. (n = 6) demonstrated raised MICs to all antifungal drugs tested, with the lowest being to voriconazole and amphotericin B (AmB), respectively (geometric mean MICs of 3.4 mg/L and 2.2 mg/L, respectively). All Scedosporium apiospermum complex isolates (n = 14) were inhibited by voriconazole concentrations of ≤0.25 mg/L, followed by posaconazole and itraconazole at ≤1 mg/L. Posaconazole and AmB were the most active agents against the Mucorales, with MIC90 values of 1 mg/L and 2 mg/L, respectively, for Rhizopus spp. For dematiaceous fungi, all isolates were inhibited by itraconazole and posaconazole concentrations of ≤0.5 mg/L (MIC90, 0.12 mg/L and 0.25 mg/L, respectively), but voriconazole and AmB also had in vitro activity (MIC90, 0.5 mg/L and 1 mg/L, respectively). Differences in antifungal susceptibility within species and between species within genera support the need for testing individual patient isolates to guide therapy. The Sensititre(®) YeastOne(®) offers a practical alternative to the reference methodology for susceptibility testing of moulds.

  6. Role of a T-type calcium current in supporting a depolarizing potential, damped oscillations, and phasic firing in vasopressinergic guinea pig supraoptic neurons.

    Guinea pig magnocellular neurosecretory cells (MNCs) of the supraoptic nucleus (SON) were studied using the in vitro slice preparation. Intracellular recordings were made with biocytin-filled electrodes, permitting immunocytochemical identification of the recorded cells as arginine vasopressin- (AVP) versus oxytocin- (OT) containing. Only AVP cells displaying a depolarizing potential (DP) fired phasically. The DP was associated with a transient inward current measured in voltage clamp, which exhibited a number of properties of the T-type calcium current: activation threshold of -64 mV, time course of up to 250 ms, blockade by nickel and augmentation by barium chloride. This current has not been reported previously in SON neurons. The T-type current (IT) was always associated with a damped oscillation of the membrane following the offset from hyperpolarizing steps. In all cells tested, an apamin-sensitive afterhyperpolarization (AHP) was observed, similar to the calcium-dependent potassium current (IK, Ca) described in rat SON and other CNS regions. Therefore, as with other CNS regions displaying damped oscillations, guinea pig SON cells possess both an IT and an IK, Ca. We have previously described an Ih activating at hyperpolarized potentials in these cells, which depolarizes the membrane to a range in which the IT and IK, Ca can interactively support oscillations. In summary, the IT and associated depolarizing potential appears to be a requisite feature for phasic firing in AVP cells of guinea pig SON.

    In the United States, potential offshore wind plant sites have been identified along the Atlantic seaboard and in the Gulf of Mexico. It is imperative that we define external conditions associated with hurricanes and severe winter storms and consider load cases for which wind turbines may need to be designed. We selected two hurricanes, Ike (2008) and Sandy (2012), and investigated the effect these tropical storms would have on bottom-supported offshore wind turbines that were hypothetically in or close to their path as they made landfall. For realistic turbine loads assessment, it is important that the coupled influences of the changing wind, wave, and current fields are simulated throughout the evolution of the hurricanes. We employed a coupled model--specifically, the University of Miami Coupled Model (UMCM)--that integrates atmospheric, wave, and ocean components to produce needed wind, wave, and current data. The wind data are used to generate appropriate vertical wind profiles and full wind velocity fields including turbulence; the current field over the water column is obtained by interpolated discrete output current data; and short-crested irregular second-order waves are simulated using output directional wave spectra from the coupled model. We studied two monopile-supported offshore wind turbines sited in 20 meters of water in the Gulf of Mexico to estimate loads during Hurricane Ike, and a jacket space-frame platform-supported offshore wind turbine sited in 50 meters of water in the mid-Atlantic region to estimate loads during Hurricane Sandy. In this report we discuss in detail how the simulated hurricane wind, wave, and current output data are used in turbine loads studies. In addition, important characteristics of the external conditions are studied, including the relative importance of swell versus wind seas, aerodynamic versus hydrodynamic forces, current velocity effects, yaw control options for the turbine, hydrodynamic drag versus inertia forces

    This study aimed to evaluate the relative importance of body change strategies and weight perception in adolescent depression after accounting for established risk factors for depression, namely low social support across key adolescent contexts. The moderating effect of self-esteem was also examined. Participants (N=4587, 49% female) were selected from the National Longitudinal Study of Adolescent Health. Regression analyses were conducted on the association between well-known depression risk factors (lack of perceived support from parents, peers, and schools), body change strategies, weight perception, and adolescent depressive symptoms one year later. Each well-known risk factor significantly predicted depressive symptoms. Body change strategies related to losing weight and overweight perceptions predicted depressive symptoms above and beyond established risk factors. Self-esteem moderated the relationship between trying to lose weight and depressive symptoms. Maladaptive weight loss strategies and overweight perceptions should be addressed in early identification depression programs. Copyright © 2013 Elsevier Inc. All rights reserved.

    Objective To investigate the co-effect of Demand-control-support (DCS) model and Effort-reward Imbalance (ERI) model on the risk estimation of depression in humans in comparison with the effects when they are used respectively. Methods A total of 3 632 males and 1 706 females from 13 factories and companies in Henan province were recruited in this cross-sectional study. Perceived job stress was evaluated with the Job Content Questionnaire and Effort-Reward Imbalance Questionnaire (Chinese version). Depressive symptoms were assessed by using the Center for Epidemiological Studies Depression Scale (CES-D). Results DC (demands/job control ratio) and ERI were shown to be independently associated with depressive symptoms. The outcome of low social support and overcommitment were similar. High DC and low social support (SS), high ERI and high overcommitment, and high DC and high ERI posed greater risks of depressive symptoms than each of them did alone. ERI model and SS model seem to be effective in estimating the risk of depressive symptoms if they are used respectively. Conclusion The DC had better performance when it was used in combination with low SS. The effect on physical demands was better than on psychological demands. The combination of DCS and ERI models could improve the risk estimate of depressive symptoms in humans.

  14. The Utilisation of Pisang Island as a Platform to Support the Current Safety and Security Needs of Marine Navigation in the Straits of Malacca

    Full Text Available Current marine navigational practice relies less on long-range visual marine signals such as lighthouses for reference purposes. This is due to the availability of Global Navigation Satellite Systems (GNSS, which are integrated with other navigational aids on ships. Therefore, the objective of this study is to review the function of Pisang Island lighthouse and to propose the most relevant use of Pisang Island for current navigational needs. The function of the lighthouse was reviewed according to the IALA Navigational Guide and the AIS data image. The result showed that the most suitable navigational use of the lighthouse is to act as a reference for Line of Position (LOP. The AIS data image indicated that mariners are not using Pisang Island lighthouse for LOP. The trend in the Straits of Malacca (SoM was compared with the trend in the Straits of Dover, UK. The selected experts verified that LOP was not practised there. As a specific example, a tanker ship route in the South China Sea was used to further support that LOP was not practised. This evidence supported the view that Pisang Island lighthouse is less relevant for current navigational practice and does not directly support the coastal state VTS operation and the establishment of the marine electronic highway. Furthermore, the existing shore-based VTS radar has limitations on range and the detection of targets near Pisang Island. Therefore, this study proposes the establishment of a new radar station on Pisang Island at the existing site of the lighthouse. The proposed new radar station on Pisang Island will add to the existing coverage of the VTS radar, bridging the coverage gaps to overcome the weakness of the existing shore-based radar and improve the safety and security of marine navigation in the SoM.

    This paper presents an investigation of vibration and current monitoring for effective fault prediction in induction motor (IM) by using multiclass support vector machine (MSVM) algorithms. Failures of IM may occur due to propagation of a mechanical or electrical fault. Hence, for timely detection of these faults, the vibration as well as current signals was acquired after multiple experiments of varying speeds and external torques from an experimental test rig. Here, total ten different fault conditions that frequently encountered in IM (four mechanical fault, five electrical fault conditions and one no defect condition) have been considered. In the case of stator winding fault, and phase unbalance and single phasing fault, different level of severity were also considered for the prediction. In this study, the identification has been performed of the mechanical and electrical faults, individually and collectively. Fault predictions have been performed using vibration signal alone, current signal alone and vibration-current signal concurrently. The one-versus-one MSVM has been trained at various operating conditions of IM using the radial basis function (RBF) kernel and tested for same conditions, which gives the result in the form of percentage fault prediction. The prediction performance is investigated for the wide range of RBF kernel parameter, i.e. gamma, and selected the best result for one optimal value of gamma for each case. Fault predictions has been performed and investigated for the wide range of operational speeds of the IM as well as external torques on the IM.

    To investigate the scope and nature of discrimination and positive treatment experienced by adults with mental health problems from their friends and family in a population-based survey. An Australian telephone-survey of 5220 adults included 1381 individuals who reported a mental health problem or scored high on a screening questionnaire. Respondents were interviewed about their experience of discrimination and positive treatment from their friends, spouse and other family members. Descriptions of experiences were content-analysed to identify key characteristics. Mental health diagnoses were primarily depression or anxiety disorders, and just over half had received treatment in the last 12 months. Positive treatment from family and friends was far more common than discrimination, reported by 74.1% of respondents. This was primarily characterised by providing emotional support and maintaining contact, as well as checking on their mental health and being a good listener. Nevertheless, discriminatory behaviours from friends and family were reported by 25.8% of respondents, with reducing or cutting contact being by far the most common. Friends and family also commonly dismissed that mental illness was real or caused suffering and showed a lack of understanding about mental health problems or treatments and how they can impact behaviour and functioning. This nationally representative study of real life experiences highlights the potential for harm or benefit from a person's social support network. Despite positive experiences being common, there is an ongoing need to reduce mental illness stigma and improve understanding of how to support a loved one with a mental health problem.

OncoDoc2 is a decision support system designed to support treatment decisions of multidisciplinary meetings (MDMs) for breast cancer patients. We evaluated how the way the system was used had an impact on MDM decision compliance with clinical practice guidelines. We distinguished "correct navigations" (N+), "incorrect navigations" (N-), and "missing navigations" (N0), according to the quality of data entry when using OncoDoc2. We collected 557 MDM decisions from three hospitals of Paris area (France) where OncoDoc2 was routinely used. We observed 33.9% N+, 36.8% N-, and 29.3% N0. The compliance rate was significantly different according to the quality of navigations, 94.2%, 80.0%, and 90.2% for N+, N-, and N0 respectively. Surprinsingly, it was better not to use the system (N0) than to use it improperly (N-).

    2007-09-01

    Employers' duties of care under both common and statute law include the need to take reasonable care of the health and safety of the workforce. This includes both the moral and legal duties to consider the psychological needs of personnel following exposure to traumatic events related to the workplace. While this has been recognized within many high-risk occupations such the police, fire and rescue services and the military, there is also evidence that post-trauma support in the workplace is increasingly commonly provided not only among health and social services agencies, but within many private sector organizations. Over the past decade, however, there has been considerable controversy over the provision of early psychological support to personnel in the form of critical incident stress management (CISM) processes. In particular, one aspect of CISM, the use of psychological debriefing (PD) has come under scrutiny and criticism as two studies indicated that PD was ineffective and had the potential to do harm. Inevitably, this has provoked much uncertainty and confusion among some organizations as what should be the most appropriate support. It has also led to misconceptions and misunderstandings as to the aims and purpose of PD, together with inaccuracies of terminology, for example describing PD as 'counselling'. Despite the controversy, both CISM and PD continue to be provided on a widespread basis, often utilizing a framework of voluntary peer group support. This paper intends to (i) present a review of the current status of CISM practices, including the use of PD within various organizations in the UK and (ii) provide a clear framework and understanding of the main issues and to clarify conceptual misunderstandings. The history, principles and background of the use of post-trauma support in the workplace, charting trends over the past two decades, previous research, problems with the evidence base and current thinking and practice in the field are reviewed

    The main objective of the article is to highlight the role that Web2.0 currently has and could have in the future in supporting the teaching of ICT Design for All. According to this, first the concepts of Web2.0 and eLearning2.0 are clarified and connected. The new way of thinking about eLearning being inspired by the emergence of Web2.0, the term eLearning2.0 was introduced to identify a new paradigm. So, eLearning 2.0, by contrast to eLearning1.0 is built around collaboration, also eLearning2.0 assumes that knowledge is socially constructed. Related to the role of Web2.0 in supporting the teaching of ICT Design for All, the 4 steps involved by the ICT Design For All Teaching Principles are presented and detailed. Finally, some real world examples are shown, as evidence of how the new methods of communication offered by Web2.0 can be used to support students as they learn about Design for All.

    Background SaltSwitch is an innovative smartphone application (app) that enables shoppers to scan the barcode of a packaged food and receive an immediate, interpretive, traffic light nutrition label on the screen, along with suggestions for lower salt alternatives. Our aim was to determine the effectiveness of SaltSwitch to support people with cardiovascular disease to make lower salt food choices. Design Six-week, two-arm, parallel, randomised controlled trial in Auckland, New Zealand (2 weeks baseline and 4 weeks intervention). Methods Sixty-six adults with diagnosed cardiovascular disease (mean (SD) age 64 (7) years) were randomly assigned in a 1:1 ratio to either the SaltSwitch smartphone app or control (usual care). The primary outcome was the salt content of household packaged food purchases during the 4-week intervention (g/MJ). Secondary outcomes were the saturated fat content (g/MJ), energy content (kJ/kg) and expenditure (NZ$) of household food purchases; systolic blood pressure (mmHg), urinary sodium (mg) and use and acceptability of the SaltSwitch app. Results Thirty-three participants with cardiovascular disease were allocated to the SaltSwitch intervention, and 33 to the control group. A significant reduction in mean household purchases of salt was observed (mean difference (95% confidence interval), -0.30 (-0.58 to -0.03) g/MJ), equating to a reduction of ∼0.7 g of salt per person per day during the 4-week intervention phase. There were no significant between-group differences in any secondary outcomes (all P > 0.05). Conclusions The SaltSwitch smartphone app is effective in supporting people with cardiovascular disease to make lower salt food purchases. A larger trial with longer follow-up is warranted to determine the effects on blood pressure.

    Full Text Available The purpose of this randomized controlled study is to investigate the clinical results obtained over four years and incidence of complications associated with one- versus two-piece custom made zirconia anchorages, in single tooth implant-supported restorations of the maxillary anterior region. Sixty-five patients, with a total of 74 missing maxillary teeth, were selected in the period from February 2007 to July 2010. Two different ways of custom made zirconia abutment and final prosthetic restoration were evaluated: a standard zirconia abutment associated with a pressed layer of lithium disilicate with an all-ceramic cemented restoration versus one-piece restoration with the facing porcelain fired and pressed straight to the custom made zirconia abutment. In 29 cases, the restoration consisted of an all-ceramic restoration for cementation (two pieces; in 45 cases the restoration was a screw-retained restoration (one piece. Three all-ceramic restorations broke during the observation time. Two one-piece restorations fractured after 26 months. At follow-up examination there were no significant differences between one-piece and two-piece groups regarding the PI, BI, and MBL. Awaiting studies with longer follow-up times, a careful conclusion is that zirconia anchorages for single-implant restorations seem to demonstrate good short-term technical and biological results.

    Australia has high initiation rates of breastfeeding, but the challenges of establishing and maintaining breastfeeding in the first few months of infant life result in many women changing to artificial formula feeding. This paper reports on the impact of a new strategy to improve breastfeeding duration rates in the first 8 weeks post-partum. The Earlybird Program (EBP) combines the professional expertise of child and family health (C&FH) nurses with the expertise of the participating mothers to support each other in establishing breastfeeding in the first 8 weeks. This retrospective study compared the breastfeeding patterns of first-time mothers who attended the EBP, with the breastfeeding patterns of mothers who accessed individual appointments with the nurses in a 12-month period, and examined the predictors of continued breastfeeding at 8 weeks. The total sample comprised 193 infant records. Women who selected the EBP were more likely to be employed and less likely to be categorized as non-English speaking background. These women also had more visits to the C&FH service. Logistic regression was used to determine the factors associated with breastfeeding cessation at 8 weeks post-natal. After adjusting for variables, only exclusive breastfeeding at first visit and attending the EBP were significant predictors of continuing to breastfeed at 8 weeks. Facilitation skills that recognize the expertise of participating women were considered an important aspect of the programme.

    The electrochemical reaction mechanism of ZnO is investigated to understand its Li insertion/extraction behavior using ex situ X-ray diffraction, extended X-ray absorption fine structure, and high-resolution transmission electron microscopy. Based on these analyses, an interesting partial recombination reaction of ZnO is discovered, which demonstrates that Li2O formed during Li insertion is partially reversible. Additionally, we discover that the control of the partial recombination reaction of the metal oxide is very important for improving reversibility in the first cycle, which is a key finding for realization of highly reversible oxide-based electrode materials. In addition, to enhance the electrochemical performance of the ZnO electrode, a nanostructured ZnO/C composite is prepared by a simple high-energy mechanical milling process. This process allows the electrochemical performance of the ZnO electrode to be evaluated as an anode for rechargeable Li-ion batteries. Electrochemical tests show that the nanocomposite electrode exhibits a high initial charge capacity of 682 mAh g-1, fast rate capability of 371 mAh g-1 at 2 C, and excellent cyclability over 200 cycles.

    This article is part of a series written for people responsible for making decisions about health policies and programmes and for those who support these decision makers. In this article we address considerations of equity. Inequities can be defined as "differences in health which are not only unnecessary and avoidable but, in addition, are considered unfair and unjust". These have been well documented in relation to social and economic factors. Policies or programmes that are effective can improve the overall health of a population. However, the impact of such policies and programmes on inequities may vary: they may have no impact on inequities, they may reduce inequities, or they may exacerbate them, regardless of their overall effects on population health. We suggest four questions that can be considered when using research evidence to inform considerations of the potential impact a policy or programme option is likely to have on disadvantaged groups, and on equity in a specific setting. These are: 1. Which groups or settings are likely to be disadvantaged in relation to the option being considered? 2. Are there plausible reasons for anticipating differences in the relative effectiveness of the option for disadvantaged groups or settings? 3. Are there likely to be different baseline conditions across groups or settings such that that the absolute effectiveness of the option would be different, and the problem more or less important, for disadvantaged groups or settings? 4. Are there important considerations that should be made when implementing the option in order to ensure that inequities are reduced, if possible, and that they are not increased?

    Brain single-photon-emission-computerized tomography (SPECT) with I-ioflupane (I-FP-CIT) is useful to diagnose Parkinson disease (PD). To investigate the diagnostic performance of I-FP-CIT brain SPECT with semiquantitative analysis by Basal Ganglia V2 software (BasGan), we evaluated semiquantitative data of patients with suspect of PD by a support vector machine classifier (SVM), a powerful supervised classification algorithm.I-FP-CIT SPECT with BasGan analysis was performed in 90 patients with suspect of PD showing mild symptoms (bradykinesia-rigidity and mild tremor). PD was confirmed in 56 patients, 34 resulted non-PD (essential tremor and drug-induced Parkinsonism). A clinical follow-up of at least 6 months confirmed diagnosis. To investigate BasGan diagnostic performance we trained SVM classification models featuring different descriptors using both a "leave-one-out" and a "five-fold" method. In the first study we used as class descriptors the semiquantitative radiopharmaceutical uptake values in the left (L) and right (R) putamen (P) and in the L and R caudate nucleus (C) for a total of 4 descriptors (CL, CR, PL, PR). In the second study each patient was described only by CL and CR, while in the third by PL and PR descriptors. Age was added as a further descriptor to evaluate its influence in the classification performance.I-FP-CIT SPECT with BasGan analysis reached a classification performance higher than 73.9% in all the models. Considering the "Leave-one-out" method, PL and PR were better predictors (accuracy of 91% for all patients) than CL and CR descriptors; using PL, PR, CL, and CR diagnostic accuracy was similar to that of PL and PR descriptors in the different groups. Adding age as a further descriptor accuracy improved in all the models. The best results were obtained by using all the 5 descriptors both in PD and non-PD subjects (CR and CL + PR and PL + age = 96.4% and 94.1%, respectively). Similar results were observed for the "five

    利用2014年中国老年社会追踪调查(CLASS)数据作为支持,从老年人对家庭养老模式和具体的家庭养老方式的态度和看法这两个维度,阐释我国家庭养老观念的现状和变化。研究发现:家庭养老模式方面,孝观念和孝行标准在当代社会的文化氛围下有着新的表现形式,今天的老年人更加注重子女对自己日常生活的照料;在具体的家庭养老方式方面,对于“谁来养老”,老年人尤其是城市、低龄老年人的“养儿防老”观念正在逐渐淡化,对于“在哪养老”,从总体上看,无论是老年人还是其家庭成员,大都希望居家养老。%By using the data from Chinese Longitudinal Aging Social Survey (CLASS) which is directed by Renmin University of China, this paper interprets the current situation and tendency of family support perception from 2 dimensions:family support pattern and the action style of family support. The paper has found that filial piety perception is changing in recent days and the old persons are more emphasis on children’s care for them in family support pattern aspect. Furthermore, in the aspect of family support action style, the perspective for“raise children to provide against old age”is diminishing especially for the urban and low age old people. Moreover, both old people and their family members are inclined that the old are expected to be at home when they are old.

    On September 29, 2005, ASME Standards Technology, LLC (ASME ST-LLC) executed a multi-year, cooperative agreement with the United States DOE for the Generation IV Reactor Materials project. The project's objective is to update and expand appropriate materials, construction, and design codes for application in future Generation IV nuclear reactor systems that operate at elevated temperatures. Task 4 was embarked upon in recognition of the large quantity of ongoing reactor designs utilizing high temperature technology. Since Code Case N-201 had not seen a significant revision (except for a minor revision in September, 2006 to change the SA-336 forging reference for 304SS and 316SS to SA-965 in Tables 1.2(a) and 1.2(b), and some minor editorial changes) since December 1994, identifying recommended updates to support the current high temperature Core Support Structure (CSS) designs and potential new designs was important. As anticipated, the Task 4 effort identified a number of Code Case N-201 issues. Items requiring further consideration range from addressing apparent inconsistencies in definitions and certain material properties between CC-N-201 and Subsection NH, to inclusion of additional materials to provide the designer more flexibility of design. Task 4 developed a design parameter survey that requested input from the CSS designers of ongoing high temperature gas cooled reactor metallic core support designs. The responses to the survey provided Task 4 valuable input to identify the design operating parameters and future needs of the CSS designers. Types of materials, metal temperature, time of exposure, design pressure, design life, and fluence levels were included in the Task 4 survey responses. The results of the survey are included in this report. This research proves that additional work must be done to update Code Case N-201. Task 4 activities provide the framework for the Code Case N-201 update and future work to provide input on materials. Candidate

    The challenges of the LHC project have lead CERN to produce a comprehensive set of project management tools covering engineering data management, project scheduling and costing, event management and document management. Each of these tools represents a significant and world-recognised advance in their respective domains. Reviewing the offering on the eve of LHC commissioning one can identify three major challenges: 1. How to integrate the tools to provide a uniform and integrated full-product lifecycle solution 2. How to evolve the functionality in certain areas to address weaknesses identified with our experience in constructing the LHC and integrate emerging industry best practices 3. How to coherently package the offering not just for future projects in CERN, but moreover in the context of providing a centre of excellence for worldwide collaboration in future HEP projects.

    Two articles in the current issue of the Psychiatric Rehabilitation Journal bring into focus the important question of the importance of work, and in particular meaningful employment, in people with a serious mental illness. Gewurtz, Cott, Rush, and Kirsh (see record 2012-34112-003) present findings from a change in policy in Canada for the funding of vocational services for people with a serious mental illness from a fee-for-service model to an outcomes-based model, with reimbursement based on successful competitive job placement and retention, irrespective of job type and consumer preference. The results indicated increased rates of competitive work, mainly in entry-level jobs, but they also raised questions as to whether the narrow focus on job attainment may have been at the cost of less career development and ultimately less meaningful work for the consumers. Baksheev, Allott, Jackson, McGorry, and Killackey (see record 2012-34112-002) found that a combined supported employment and education program for people with a first episode of psychosis led to higher rates of employment and class completion than usual services. The analysis presented in this report showed that no individual consumer characteristics other than program assignment (supported employment and education vs. usual services) predicted vocational or educational outcomes. The findings underscore the potency of supported employment, and suggest that combining it with educational services may be fruitful for people who have recently experienced an episode of psychosis. These findings raise several questions that will be touched on in this editorial, including: Why are career development and supported education important? What have we learned about supported education? What are the current gaps in our knowledge about supported education?

    为了解决主数据集成、web数据集成中的真值发现问题,提出了一种基于模糊偏序关系支持度计算模型的真值发现算法(FA-SDCM)。针对已有算法中,以描述相似度替代描述支持度进行计算,忽视了描述所含真值信息的不对称性问题,在分析描述本身特性的基础上,提出了描述蕴含概念,定义了基于模糊偏序关系的支持度计算模型,较好地解决了描述所含真值信息的不对称性问题。在考虑了数据源可信度及描述之间支持度对真值发现影响的基础上,基于迭代思想,提出了FA-SDCM算法。在Books-Authors数据集上进行实验,结果表明FA-SDCM算法比Vot e算法与TruthFinder算法具有更高的准确率。%In order to find the true values in master data integration and web data integration, we propose a true value finding algorithm (FA-SDCM) based on a support degree calculation model using fuzzy partial order relations. In existing algorithms, support degrees are usually substituted by similarity, which ignores the asymmetry in the true vales. In this paper, the concept of description containing is proposed through analyzing characteristics of descriptions, and then a support degree calculating model is developed based on fuzzy partial order relations to solve the description of asymmetric problems in the true values. Considering the influence of the data source reliability and the support degrees among descriptions on true value finding, the FA-SDCM algorithm is realized iteratively. An experiment has been carried on the Books-Authors data set, and the result shows that the FA-SDCM algorithm has better accuracy than the Vote and the TruthFinder algorithms.

  11. Bioartificial liver: current status.

    Science.gov (United States)

    Pless, G; Sauer, I M

    2005-11-01

    Liver failure remains a life-threatening syndrome. With the growing disparity between the number of suitable donor organs and the number of patients awaiting transplantation, efforts have been made to optimize the allocation of organs, to find alternatives to cadaveric liver transplantation, and to develop extracorporeal methods to support or replace the function of the failing organ. An extracorporeal liver support system has to provide the main functions of the liver: detoxification, synthesis, and regulation. The understanding that the critical issue of the clinical syndrome in liver failure is the accumulation of toxins not cleared by the failing liver led to the development of artificial filtration and adsorption devices (artificial liver support). Based on this hypothesis, the removal of lipophilic, albumin-bound substances, such as bilirubin, bile acids, metabolites of aromatic amino acids, medium-chain fatty acids, and cytokines, should be beneficial to the clinical course of a patient in liver failure. Artificial detoxification devices currently under clinical evaluation include the Molecular Adsorbent Recirculating System (MARS), Single-Pass Albumin Dialysis (SPAD), and the Prometheus system. The complex tasks of regulation and synthesis remain to be addressed by the use of liver cells (bioartificial liver support). The Extracorporeal Liver Assist Device (ELAD), HepatAssist, Modular Extracorporeal Liver Support system (MELS), and the Amsterdam Medical Center Bioartificial Liver (AMC-BAL) are bioartificial systems. This article gives a brief overview on these artificial and bioartificial devices and discusses remaining obstacles.

  13. Immunological findings in autism.

    Science.gov (United States)

    Cohly, Hari Har Parshad; Panja, Asit

    2005-01-01

    The immunopathogenesis of autism is presented schematically in Fig. 1. Two main immune dysfunctions in autism are immune regulation involving pro-inflammatory cytokines and autoimmunity. Mercury and an infectious agent like the measles virus are currently two main candidate environmental triggers for immune dysfunction in autism. Genetically immune dysfunction in autism involves the MHC region, as this is an immunologic gene cluster whose gene products are Class I, II, and III molecules. Class I and II molecules are associated with antigen presentation. The antigen in virus infection initiated by the virus particle itself while the cytokine production and inflammatory mediators are due to the response to the putative antigen in question. The cell-mediated immunity is impaired as evidenced by low numbers of CD4 cells and a concomitant T-cell polarity with an imbalance of Th1/Th2 subsets toward Th2. Impaired humoral immunity on the other hand is evidenced by decreased IgA causing poor gut protection. Studies showing elevated brain specific antibodies in autism support an autoimmune mechanism. Viruses may initiate the process but the subsequent activation of cytokines is the damaging factor associated with autism. Virus specific antibodies associated with measles virus have been demonstrated in autistic subjects. Environmental exposure to mercury is believed to harm human health possibly through modulation of immune homeostasis. A mercury link with the immune system has been postulated due to the involvement of postnatal exposure to thimerosal, a preservative added in the MMR vaccines. The occupational hazard exposure to mercury causes edema in astrocytes and, at the molecular level, the CD95/Fas apoptotic signaling pathway is disrupted by Hg2+. Inflammatory mediators in autism usually involve activation of astrocytes and microglial cells. Proinflammatory chemokines (MCP-1 and TARC), and an anti-inflammatory and modulatory cytokine, TGF-beta1, are consistently

  15. An effective and practical method for solving an unnegligible problem inherent in the current calculation model for multi-support seismic analysis of structures

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    In the seismic analysis of extended structures subject to spatially varying motions, the displacement input model instead of acceleration model is usually adopted for accurate results. In this paper, a more detailed and comprehensive analysis of the displacement input model is carried out and the research shows that there exists an unnegligible problem in the current displacement model, which leads to the irrationality and unconvergence of some calculated results such as base shear etc. Based on the situation, an effective method named massless rigid element (MRE) method is presented to solve the problem. Moreover, the rationality and accuracy of the method are further assessed and the method is applied to a transmission tower-line system project using the commercially available structural analysis software SAP2000. The theoretical and numerical analyses indicate that the MRE approach is not only feasible with sufficient computational accuracy but also practical and can be easily implemented using the commercially available finite element software such as SAP2000.

    2007-01-01

    User support in a grid environment is a challenging task due to the distributed nature of the grid. The variety of users and VOs adds further to the challenge. One can find support requests by grid beginners, users with specific applications, site administrators, or grid monitoring operators. With the GGUS infrastructure, EGEE provides a portal where users can find support in their daily use of the grid. The current use of the system has shown that the goal has been achieved with success. The grid user support model in EGEE can be captioned ‘regional support with central coordination’. Users can submit a support request to the central GGUS service, or to their Regional Operations' Centre (ROC) or to their Virtual Organisation helpdesks. Within GGUS there are appropriate support groups for all support requests. The ROCs and VOs and the other project wide groups such as middleware groups (JRA), network groups (NA), service groups (SA) and other grid infrastructures (OSG, NorduGrid, etc.) are connected via a...

    The precise estimation of the global agricultural cropland- extents, areas, geographic locations, crop types, cropping intensities, and their watering methods (irrigated or rainfed; type of irrigation) provides a critical scientific basis for the development of water and food security policies (Thenkabail et al., 2012, 2011, 2010). By year 2100, the global human population is expected to grow to 10.4 billion under median fertility variants or higher under constant or higher fertility variants (Table 1) with over three quarters living in developing countries, in regions that already lack the capacity to produce enough food. With current agricultural practices, the increased demand for food and nutrition would require in about 2 billion hectares of additional cropland, about twice the equivalent to the land area of the United States, and lead to significant increases in greenhouse gas productions (Tillman et al., 2011). For example, during 1960-2010 world population more than doubled from 3 billion to 7 billion. The nutritional demand of the population also grew swiftly during this period from an average of about 2000 calories per day per person in 1960 to nearly 3000 calories per day per person in 2010. The food demand of increased population along with increased nutritional demand during this period (1960-2010) was met by the “green revolution” which more than tripled the food production; even though croplands decreased from about 0.43 ha/capita to 0.26 ha/capita (FAO, 2009). The increase in food production during the green revolution was the result of factors such as: (a) expansion in irrigated areas which increased from 130 Mha in 1960s to 278.4 Mha in year 2000 (Siebert et al., 2006) or 399 Mha when you do not consider cropping intensity (Thenkabail et al., 2009a, 2009b, 2009c) or 467 Mha when you consider cropping intensity (Thenkabail et al., 2009a; Thenkabail et al., 2009c); (b) increase in yield and per capita food production (e.g., cereal production

    2014-10-01

    State-of-the-art neuroimaging techniques have accelerated progress in the study and understanding of sleep in humans. Neuroimaging studies in primary insomnia remain relatively few, considering the important prevalence of this disorder in the general population. This review examines the contribution of functional and structural neuroimaging to our current understanding of primary insomnia. Functional studies during sleep provided support for the hyperarousal theory of insomnia. Functional neuroimaging also revealed abnormalities in cognitive and emotional processing in primary insomnia. Results from structural studies suggest neuroanatomical alterations in primary insomnia, mostly in the hippocampus, anterior cingulate cortex and orbitofrontal cortex. However, these results are not well replicated across studies. A few magnetic resonance spectroscopy studies revealed abnormalities in neurotransmitter concentrations and bioenergetics in primary insomnia. The inconsistencies among neuroimaging findings on insomnia are likely due to clinical heterogeneity, differences in imaging and overall diversity of techniques and designs employed. Larger samples, replication, as well as innovative methodologies are necessary for the progression of this perplexing, yet promising area of research. Copyright © 2014 Elsevier Masson SAS.

    This study examined support for and reported compliance with smoke-free policy in air-conditioned restaurants and other similar places among adult smokers in Malaysia and Thailand. Baseline data (early 2005) from the International Tobacco Control Southeast Asia Survey (ITC-SEA), conducted face-to-face in Malaysia and Thailand (n = 4005), were used. Among those attending venues, reported total smoking bans in indoor air-conditioned places such as restaurants, coffee shops, and karaoke lounges were 40% and 57% in Malaysia and Thailand, respectively. Support for a total ban in air-conditioned venues was high and similar for both countries (82% Malaysian and 90% Thai smokers who believed there was a total ban), but self-reported compliance with bans in such venues was significantly higher in Thailand than in Malaysia (95% vs 51%, P air-conditioned venues was associated with a greater support for a ban in such venues in both countries.

    2004-01-01

    The purposes of this study are to compare the current Space Shuttle Ground Support Equipment (GSE) infrastructure with the proposed GSE infrastructure upgrade modification. The methodology will include analyzing the first prototype installation equipment at Launch PAD B called the "Pathfinder". This study will begin by comparing the failure rate of the current components associated with the "Hardware interface module (HIM)" at the Kennedy Space Center to the failure rate of the neW Pathfinder components. Quantitative data will be gathered specifically on HIM components and the PAD B Hypergolic Fuel facility and Hypergolic Oxidizer facility areas which has the upgraded pathfinder equipment installed. The proposed upgrades include utilizing industrial controlled modules, software, and a fiber optic network. The results of this study provide evidence that there is a significant difference in the failure rates of the two studied infrastructure equipment components. There is also evidence that the support staff for each infrastructure system is not equal. A recommendation to continue with future upgrades is based on a significant reduction of failures in the new' installed ground system components.

    Objective To assess the influence of newspaper coverage and a media campaign about Dutch smoke-free legislation on smokers’ support for smoke-free bars and restaurants and on second-hand smoke (SHS) harm awareness. Design and main outcome measures A content analysis was conducted of 1,041 newspaper articles on the smoke-free legislation published in six Dutch newspapers from March 2008 until April 2009. Smokers who were regular readers of at least one of these newspapers (n = 677) were selected from the pre- and post-ban waves of the International Tobacco Control (ITC) Netherlands Survey. Exposure to newspaper coverage and to the implementation campaign were correlated with changes in smokers’ support for smoke-free bars and restaurants and SHS harm awareness. Results Most newspaper coverage was found to be negative towards the smoking ban (57%) and focused on economic aspects (59%) rather than health aspects (22%). Exposure to this coverage had a small but significantly negative effect on support for smoke-free bars and restaurants (Beta = −0.09, p = 0.013). Among higher educated smokers, exposure to positive newspaper coverage had a more positive effect on support for smoke-free bars and restaurants. In addition, exposure to the implementation campaign had a small but significantly positive effect on SHS harm awareness (Beta = 0.11, p = 0.001). Conclusions Media attention about smoke-free legislation can influence smokers’ support for the legislation and SHS harm awareness. Tobacco control advocates should aim to establish positive media attention that puts forward the health arguments for the legislation. PMID:21586760

    Full Text Available In order to improve the performance of voltage source converter-high voltage direct current (VSC-HVDC system, we propose an improved auto-disturbance rejection control (ADRC method based on least squares support vector machines (LSSVM in the rectifier side. Firstly, we deduce the high frequency transient mathematical model of VSC-HVDC system. Then we investigate the ADRC and LSSVM principles. We ignore the tracking differentiator in the ADRC controller aiming to improve the system dynamic response speed. On this basis, we derive the mathematical model of ADRC controller optimized by LSSVM for direct current voltage loop. Finally we carry out simulations to verify the feasibility and effectiveness of our proposed control method. In addition, we employ the time-frequency representation methods, i.e., Wigner-Ville distribution (WVD and adaptive optimal kernel (AOK time-frequency representation, to demonstrate our proposed method performs better than the traditional method from the perspective of energy distribution in time and frequency plane.

    Many studies have provided strong evidence of a fundamental and complex role for sleep disturbances in adult posttraumatic stress disorder (PTSD). Investigations of adult PTSD using subjective and objective measures document sleep architecture abnormalities and high prevalence of sleep disordered breathing, periodic limb movement disorder, nightmares, and insomnia. PTSD treatment methods do appear to significantly improve sleep disturbance, and also studies suggest that treatments for sleep disorders often result in improvements in PTSD symptoms. Further, the most recent evidence suggests sleep abnormalities may precede the development of PTSD. Given the importance of sleep disorders to the onset, course, and treatment of adult PTSD, examination of sleep disturbances far earlier in the life course is imperative. Here we review the literature on what we know about sleep disturbances and disorders in pediatric PTSD. Our review indicates that the extant, empirical data examining sleep disturbance and disorders in pediatric PTSD is limited. Yet, this literature suggests there are significantly higher reports of sleep disturbances and nightmares in children and adolescents exposed to trauma and/or diagnosed with PTSD than in non-trauma-exposed samples. Sleep questionnaires are predominantly employed to assess sleep disorders in pediatric PTSD, with few studies utilizing objective measures. Given the important, complex relationship being uncovered between adult PTSD and sleep, this review calls for further research of sleep in children with PTSD using more specific subjective measures and also objective measures, such as polysomnography and eventually treatment trial studies.

    1998-01-01

    A current determiner having an output at which representations of input currents are provided having an input conductor for the input current and a current sensor supported on a substrate electrically isolated from one another but with the sensor positioned in the magnetic fields arising about the input conductor due to any input currents. The sensor extends along the substrate in a direction primarily perpendicular to the extent of the input conductor and is formed of at least a pair of thin-film ferromagnetic layers separated by a non-magnetic conductive layer. The sensor can be electrically connected to a electronic circuitry formed in the substrate including a nonlinearity adaptation circuit to provide representations of the input currents of increased accuracy despite nonlinearities in the current sensor, and can include further current sensors in bridge circuits.

  17. Dermoscopy Findings of Hidroacanthoma Simplex

    2014-05-01

    Full Text Available Hidroacanthoma simplex (HAS, also known as intraepidermal eccrine poroma, is a rare eccrine adnexal tumor that tends to be misdiagnosed as other types of benign skin tumor, including clonal seborrheic keratosis. Notably, HAS is sometimes misdiagnosed and treated by cryosurgery as seborrheic keratosis, which could trigger the later development of porocarcinoma. Therefore, accurate diagnosis of HAS is indispensable for dermatologists to avoid the development of malignant tumors by an unsuitable treatment. In this report, we present the characteristic dermoscopy findings of HAS. Indeed, the dermoscopy findings might be related to the melanin-rich necrotic cells in the epidermis, which are quite different from dermoscopy findings of clonal seborrheic keratosis. As a previous report suggested, it is difficult for a dermatologist to differentiate HAS from clonal seborrheic keratosis by the naked eye. Our findings might be supportive for the early diagnosis of HAS.

  18. Discovery and Use of Online Learning Resources: Case Study Findings

    2004-04-01

    Full Text Available Much recent research and funding have focused on building Internet-based repositories that contain collections of high-quality learning resources, often called ‘learning objects.’ Yet little is known about how non-specialist users, in particular teachers, find, access, and use digital learning resources. To address this gap, this article describes a case study of mathematics and science teachers’ practices and desires surrounding the discovery, selection, and use of digital library resources for instructional purposes. Findings suggest that the teacher participants used a broad range of search strategies in order to find resources that they deemed were age-appropriate, current, and accurate. They intended to include these resources with little modifications into planned instructional activities. The article concludes with a discussion of the implications of the findings for improving the design of educational digital library systems, including tools supporting resource reuse.

    The study aims were: 1) to verify the role of sentinel node biopsy (SNB) in a subset of patients with clinical N0 (cN0) invasive vulvar cancer (VC) who were still candidates for radical inguinal surgery according to the current guidelines; 2) to investigate whether a preoperative (18)F-FDG PET/CT (PET/CT) evaluation could improve the selection of node negative patients. From July 2013 to July 2016, all patients with VC admitted to our Division were evaluated by standard imaging and clinical exam. Among the patients assessed as cN0 we enrolled those unsuitable for SNB, due to: T > 4 cm, multifocal tumors, complete tumor diagnostic excision, contralateral nodal involvement and local recurrence. A preoperative PET/CT was performed. For each patient surgery included SNB, performed using a combined technique (radiotracer plus blue dye), followed by standard inguino-femoral lymphadenectomy. The reference standard was histopathology. Forty-seven patients entered the study for a total of 73 groins. Histopathology revealed 12 metastatic SNs in 9 groins. No false negative SNs were found (NPV 100%). PET/CT showed a negative predictive value of 93%. Our data suggest that SNB is accurate and safe even in cN0 patients currently excluded from this procedure, providing that a careful preoperative selection is performed. PET/CT allows a reliable assessment of LN status and may be an effective support for the selection of patients who are safe candidates for SNB.

    Some studies have reported the importance of electroencephalography (EEG) as a method for investigating abnormal parameters in psychiatric disorders. Different findings in time and frequency domain analysis with regard to central nervous system arousal during acute panic states have already been obtained. This study aimed to systematically review the EEG findings in panic disorder (PD), discuss them having a currently accepted neuroanatomical hypothesis for this pathology as a basis, and identify limitations in the selected studies. Literature search was conducted in the databases PubMed and ISI Web of Knowledge, using the keywords electroencephalography and panic disorder; 16 articles were selected. Despite the inconsistency of EEG findings in PD, the major conclusions about the absolute power of alpha and beta bands point to a decreased alpha power, while beta power tends to increase. Different asymmetry patterns were found between studies. Coherence studies pointed to a lower degree of inter-hemispheric functional connectivity at the frontal region and intra-hemispheric at the bilateral temporal region. Studies on possible related events showed changes in memory processing in PD patients when exposed to aversive stimuli. It was noticed that most findings reflect the current neurobiological hypothesis of PD, where inhibitory deficits of the prefrontal cortex related to the modulation of amygdala activity, and the subsequent activation of subcortical regions, may be responsible to trigger anxiety responses. We approached some important issues that need to be considered in further researches, especially the use of different methods for analyzing EEG signals.

  4. Predicting support for restricting food marketing to youth.

    2010-01-01

    To address the obesity crisis, public health experts recommend major reductions in the marketing of unhealthy food to youth. However, policies to restrict food marketing are not currently viewed as politically feasible. This paper examines attitudes and knowledge about food marketing and support for restricting unhealthy food marketing [corrected] among one group of constituents: parents. A survey of 807 parents found that those most likely to support food marketing restrictions were also more likely to have negative views of current food practices. [corrected] These findings suggest that increased public education about the harm caused by food marketing may increase public support for policy interventions.

    The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

    Objective. To elucidate the MR findings in iliotibial band (ITB) syndrome. Design and patients. The subjects comprised four patients (five knees) with lateral knee pain: two athletes and two non-athletes. One non-athlete was engaged in work requiring repetitive knee movement, and the other suffered from Cushing syndrome and had bilateral abnormalities. All patients were suspected of having a lateral meniscal tear prior to MR examination, but physical examination following provisional MR diagnosis warranted the final diagnosis. MR studies included fast spin echo sagittal imaging, fat-saturated fast spin echo proton density coronal imaging, and T2* radial imaging. Twelve normal volunteers were examined. Results and conclusion. Fat-saturated coronal imaging demonstrated an ill-defined, high-intensity area deep to the ITB. T2* radial imaging showed an identical, but less conspicuous, abnormality. The MR finding suggested soft tissue inflammation and/or edema rather than focal fluid collection in the bursae. The signal alteration predominated in the region beneath the posterior fibers of the ITB, thus supporting the current opinion that the posterior fibers of the ITB are tighter against the lateral femoral epicondyle than the anterior fibers. The ITB itself did not show any signal alteration or increased thickness. (orig.). With 4 figs., 1 tab.

    Full Text Available Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack of a community-wide, consensus-based, human- and machine-interpretable language for describing phenotypes and their genomic and environmental contexts is perhaps the most pressing scientific bottleneck to integration across many key fields in biology, including genomics, systems biology, development, medicine, evolution, ecology, and systematics. Here we survey the current phenomics landscape, including data resources and handling, and the progress that has been made to accurately capture relevant data descriptions for phenotypes. We present an example of the kind of integration across domains that computable phenotypes would enable, and we call upon the broader biology community, publishers, and relevant funding agencies to support efforts to surmount today's data barriers and facilitate analytical reproducibility.

    The problem of attribute reduction is an important problem related to feature selection and knowledge discovery. The problem of finding reducts with minimum cardinality is NP-hard. This paper suggests a new algorithm for finding exact reducts with minimum cardinality. This algorithm transforms the initial table to a decision table of a special kind, apply a set of simplification steps to this table, and use a dynamic programming algorithm to finish the construction of an optimal reduct. I present results of computer experiments for a collection of decision tables from UCIML Repository. For many of the experimented tables, the simplification steps solved the problem.

  5. Internet gaming addiction: current perspectives

    2013-01-01

    In the 2000s, online games became popular, while studies of Internet gaming addiction emerged, outlining the negative consequences of excessive gaming, its prevalence, and associated risk factors. The establishment of specialized treatment centers in South-East Asia, the US, and Europe reflects the growing need for professional help. It is argued that only by understanding the appeal of Internet gaming, its context, and neurobiologic correlates can the phenomenon of Internet gaming addiction be understood comprehensively. The aim of this review is to provide an insight into current perspectives on Internet gaming addiction using a holistic approach, taking into consideration the mass appeal of online games, the context of Internet gaming addiction, and associated neuroimaging findings, as well as the current diagnostic framework adopted by the American Psychiatric Association. The cited research indicates that the individual’s context is a significant factor that marks the dividing line between excessive gaming and gaming addiction, and the game context can gain particular importance for players, depending on their life situation and gaming preferences. Moreover, the cultural context is significant because it embeds the gamer in a community with shared beliefs and practices, endowing their gaming with particular meaning. The cited neuroimaging studies indicate that Internet gaming addiction shares similarities with other addictions, including substance dependence, at the molecular, neurocircuitry, and behavioral levels. The findings provide support for the current perspective of understanding Internet gaming addiction from a disease framework. The benefits of an Internet gaming addiction diagnosis include reliability across research, destigmatization of individuals, development of efficacious treatments, and the creation of an incentive for public health care and insurance providers. The holistic approach adopted here not only highlights empirical research that

The aim of this review is to provide an insight into current perspectives on Internet gaming addiction using a holistic approach, taking into consideration the mass appeal of online games, the context of Internet gaming addiction, and associated neuroimaging findings, as well as the current diagnostic framework adopted by the American Psychiatric Association. The cited research indicates that the individual's context is a significant factor that marks the dividing line between excessive gaming and gaming addiction, and the game context can gain particular importance for players, depending on their life situation and gaming preferences. Moreover, the cultural context is significant because it embeds the gamer in a community with shared beliefs and practices, endowing their gaming with particular meaning. The cited neuroimaging studies indicate that Internet gaming addiction shares similarities with other addictions, including substance dependence, at the molecular, neurocircuitry, and behavioral levels. The findings provide support for the current perspective of understanding Internet gaming addiction from a disease framework. The benefits of an Internet gaming addiction diagnosis include reliability across research, destigmatization of individuals, development of efficacious treatments, and the creation of an incentive for public health care and insurance providers. The holistic approach adopted here not only highlights empirical research that

  7. The Influence of Judgment Calls on Meta-Analytic Findings.

    Previous research has suggested that judgment calls (i.e., methodological choices made in the process of conducting a meta-analysis) have a strong influence on meta-analytic findings and question their robustness. However, prior research applies case study comparison or reanalysis of a few meta-analyses with a focus on a few selected judgment calls. These studies neglect the fact that different judgment calls are related to each other and simultaneously influence the outcomes of a meta-analysis, and that meta-analytic findings can vary due to non-judgment call differences between meta-analyses (e.g., variations of effects over time). The current study analyzes the influence of 13 judgment calls in 176 meta-analyses in marketing research by applying a multivariate, multilevel meta-meta-analysis. The analysis considers simultaneous influences from different judgment calls on meta-analytic effect sizes and controls for alternative explanations based on non-judgment call differences between meta-analyses. The findings suggest that judgment calls have only a minor influence on meta-analytic findings, whereas non-judgment call differences between meta-analyses are more likely to explain differences in meta-analytic findings. The findings support the robustness of meta-analytic results and conclusions.

    To evaluate the characteristic CT findings of neuroblastoma, we studied neuroblastomas. We analysed CT findings of available 25 cases among pathologically proved 51 neuroblastomas from Jan. 1983 to Sept. 1990. The most frequent site of origin is adrenal gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows: Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently seperated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymph nodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neuroblastomas and 25% of mediastinal neuroblastomas. The most common organ or contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings.

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions.

    To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

    Gallstone ileus is a rare complication of recurrent gallstone cholecystitis. The classic radiographic triad of small bowel obstruction, pneumobilia and ectopic gallstone on abdominal plain radiograph is described with CT imaging. Because of the better resolution of CT compared with abdominal radiography and its recent accession to emergency use, radiologists should be aware of CT findings of gallstone ileus. We report a case in which gallstone ileus was initially diagnosed by CT. (orig.)

    Balance isn't an issue of time, but an issue of choice. It's about living your values by aligning your behavior with what you believe is really important. Aligning your behavior with your values is much like any other developmental experience; the basic process involves assessment, challenge, and support. You need to determine where you are, define where you want to go, and then put into place the tools you need to get there.Balance is about more than how you spend your time. It's about how you live your life. It's about recognizing that you have control over the choices you make and aligning

  4. Current ornithology

    CERN Document Server

    1983-01-01

    The appearance of the first volume of a projected series is the occasion for comment on scope, aims, and genesis of the work. The scope of Current Ornithology is all of the biology of birds. Ornithology, as a whole-organism science, is concerned with birds at every level of bi­ ological organization, from the molecular to the community, at least from the Jurassic to the present time, and over every scholarly discipline in which bird biology is done; to say this is merely to expand a dic­ tionary definition of "ornithology. " The aim of the work, to be realized over several volumes, is to present reviews or position statements con­ cerning the active fields of ornithological research. The reviews will be relatively short, and often will be done from the viewpoint of a readily­ identified group or school. Such a work could have come into being at any time within the past fifty years, but that Current Ornithology appears now is a result of events that are only seven to eight years old. One important event wa...

    1991-08-01

    Magnetic resonance (MR) findings of the brains diagnosed to have ulegyria were reviewed. The reviewed subjects comprised six epileptic children, ranged from 2 to 16 years of age. All patients had convulsion of tonic-clonic type of various severity and had histories of ischemic-hypoxic or hypoglycemic episode in the perinatal or postnatal period. T{sub 1}-weighted images demonstrated the findings precisely reflecting the salient macroscopic features of ulegyria; localized atrophy of the brain with mushroom-shaped cortical gyri with narrow roots and relatively spared wider crowns. T{sub 2}-weighted images showed the areas of hyperintensity in the subcortical and deep white matter subjacent to the atrophic cortex, suggestive of cicatrical gliosis as well as cystic degeneration. The atrophic gyri were seen in the anterior and/or posterior parasagittal arterial border zones bilaterally with minimal asymmetry. Although these findings were nearly pathognomonic to ulegyria, polymicrogyria could mimic it since both are characterized by abnormally diminutive cortical gyri seen in epileptic children. In polymicrogyria, however, affected gyri are uniformly diminutive and not mushroom-shaped, the cortex is rather thickened than atrophic, the underlying white matter shows no focal hyperintensity, subcortical cystic changes are not present, and affected cortex is not restricted to arterial border zones. Even in one of our cases with extensive ulegyria, it was easy to differentiate it from polymicrogyria since parasagittal regions were most severely affected. Although the previous reports on ulegyria have been exclusively based on postmortem pathological examinations or experimental models, its easy recognition on MRI would contribute to further understanding of its clinical significance and mechanisms.

    We reviewed MR images of 50 patients with spondylolisthesis to disclose MR findings of spondylolysis. In almost half of our series, spondylolysis was detected as a low signal intensity band traversing in the pairs interarticularis on both T1 and T2 weighted images. Sagittal images was superior to axial image in detection of the low signal intensity band. In some patients, a focal high signal intensity accompanying the low signal intensity band was considered to be fluid collection within pseudoarthrosis due to spondylolysis on T2-weighted image.

  15. BOOK REVIEW: The Current Comparator

    1989-01-01

    . One would hardly find a standards laboratory today without an instrument employing a current comparator. The NRC program, now nearing the end of its third decade, has resulted in a large number of papers in technical journals. The fact that the results of the current-comparator program are now documented in a well-written book is a most welcome development. The material in the book is well organized and divided into seven chapters. Chapter 1 deals very briefly with the historical aspects of the development, including related work in other organizations. Chapter 2 is the longest, occupying one third of the book. It presents the background theory; the definitions and origins of the errors; and the related concepts and devices including two-stage current transformers, electronic methods for improving the performance of current transformers, and null detectors. The idea of the current comparator is developed starting from Ampere's law; and then progressing to the practical realization of measuring the line integral of the magnetic field surrounding an electric current. Such an approach, as opposed to the more common methods of analyzing transformers, has a tutorial value in explaining how the current balance is achieved. Such analysis is intuitive for air-core sensing coils with infinitesimal cross-sections and uniform winding densities. The intuitive understanding, however, becomes less obvious when high-permeability magnetic cores are used. The subject of errors is discussed thoroughly. For errors of magnetic origin, ample experimental data are provided to support the hypothesis for the cause of such errors. The cause is discussed in a macroscopic sense (non-uniform effective permeability along the torus) without going into design and processing details which could be responsible for the non-uniformities. For capacitive errors, equations have been developed to compute them from geometrical considerations. Techniques are presented to reduce both types of errors shielding

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    To evaluate the usefulness of ultrasonographic findings of the common extensor and flexor tendon in evaluation of patients with lateral and medial epicondylitis. Thirty eight elbows from twenty four patients (mean age=45.2 years) were included. Ultrasonographic examination was performed to evaluate lateral or medial epicondylitis. Epicondylitis was divided into five groups according to the severity of disease: 1) normal, 2) tendinopathy, 3) tendinopathy with a partial tear, partial tear and 4) complete tear. Change in the size of a tendon, bony change of the epicondylitis, presence or absence of calcification or echogenic foci in the common tendon and hypervascularity for each categories were also assessed. In addition, these lesions were divided into the superficial and deep according to the location of lesions. According to the severity, there were 15 cases of normal, 13 tendinopathies, 8 tendinopathies with a partial tear, 2 partial tears and 0 complete tear. Bony change was seen only in tendinopathy, tendinopathy with partial tear and partial tear. Calcification or echogenic foci were only observed in cases with tendinopathy and tendinopathy with partial tear. Hypervascularity was only seen in one case of tendinopathy. With thorough understanding of ultrasonographic findings of epicondylitis, ultrasonographic examination can be especially useful and effective in evaluating the severity and location of lesions.

    Neurofibromatosis is an uncommon but certainly not a rare hereditary disorder, probably of neuralcrest origin, involving not only neuroectoderm and mesoderm but also endoderm and characterized by cafe au lait spots and cutaneous and subcutaneous tumors, with secondary mesodermal defects responsible for protean osseous abnormalities and various manifestations in other systems. This paper is a study of confirmed 143 cases of neurofibromatosis collected for past 8 years. In this analysis, special attention was given to the selected 37 cases which showed abnormal findings on radiological examinations. Overall male to female ratio was 1 : 1.3. The most frequent kind of abnormalities was vertebral kyphoscoliosis in 12 cases. Among the more pathognomonic but uncommon abnormalities to neurofibromatosis, we experienced each 2 cases of lambdoid defect, pseudoarthrosis and renovascular hypertension, and 1 cases of sphenoid bone absence.

    Full Text Available Daria J KussPsychology Research and Behavior Management, Birmingham City University, Birmingham, UKAbstract: In the 2000s, online games became popular, while studies of Internet gaming addiction emerged, outlining the negative consequences of excessive gaming, its prevalence, and associated risk factors. The establishment of specialized treatment centers in South-East Asia, the US, and Europe reflects the growing need for professional help. It is argued that only by understanding the appeal of Internet gaming, its context, and neurobiologic correlates can the phenomenon of Internet gaming addiction be understood comprehensively. The aim of this review is to provide an insight into current perspectives on Internet gaming addiction using a holistic approach, taking into consideration the mass appeal of online games, the context of Internet gaming addiction, and associated neuroimaging findings, as well as the current diagnostic framework adopted by the American Psychiatric Association. The cited research indicates that the individual's context is a significant factor that marks the dividing line between excessive gaming and gaming addiction, and the game context can gain particular importance for players, depending on their life situation and gaming preferences. Moreover, the cultural context is significant because it embeds the gamer in a community with shared beliefs and practices, endowing their gaming with particular meaning. The cited neuroimaging studies indicate that Internet gaming addiction shares similarities with other addictions, including substance dependence, at the molecular, neurocircuitry, and behavioral levels. The findings provide support for the current perspective of understanding Internet gaming addiction from a disease framework. The benefits of an Internet gaming addiction diagnosis include reliability across research, destigmatization of individuals, development of efficacious treatments, and the creation of an incentive

    介绍了新国标GB25974.1的特点,即更加强调液压支架的安全措施和安全性能。通过与旧标准MT312对比分析可知,二者差异性主要体现在:增加了循环复合加载项目对支架进行综合性能测试,为原来次数的2~3倍;增加了让缩性能试验项目,着重考核液压支架承受顶板下沉的能力;增加了水平加载和多项集中栽荷试验项目等强度试验项目。这些变化和改进对液压支架的结构强度、耐久性能和安全性能等方面提出了更高要求。新标准基本上与国际标准接轨,该标准的颁布使我国的液压支架标准体系更加完善,对于提高我国液压支架的设计、制造和试验水平将发挥重要作用。%The features of the upcoming national standard GB 25974.1 were introduced, which more emphasized the safety measures and performance of the hydraulic support. Compared with the old standard MT 312, there were the following differences: circulation composite loading project was added for testing comprehensive performance of the support, and the number of time was 2 - 3 times of the original one; contraction performance test project was added to assess the support ability to withstand roof sinking; strength test projects such as horizontal and concentrated loading were added also. These changes and improvements raised higher requirement for the structural strength, endurance and safety performance of the hydraulic support. The new standard was almost in line with international standards. The issuance of the standard made the hydraulic support standard system more perfect, and would play an important role in enhancing the design, manufacturing and test level of the hydraulic support.

    MPLS(Multi-Protocol Label Switching) VPN(Virtual Private Network) traffic has been deployed widely, but currently only supports unicast. This paper briefly introduces several available MPLS VPN multicast approaches, and then analyzes their disadvantages. A novel mechanism that uses two-layer label stack to support MPLS VPN explicit multicast is proposed and the process is discussed in detail. The scalability and performance of the proposed mechanism are studied analytically. The result shows that our solution has great advantage over the currently available scheme in terms of saving core network bandwidth and improving the scalability.

    There has been a long-standing debate on the question of whether or not electric currents in solar active regions are neutralized. That is, whether or not the main (or direct) coronal currents connecting the active region polarities are surrounded by shielding (or return) currents of equal total value and opposite direction. Both theory and observations are not yet fully conclusive regarding this question, and numerical simulations have, surprisingly, barely been used to address it. Here we quantify the evolution of electric currents during the formation of a bipolar active region by considering a three-dimensional magnetohydrodynamic simulation of the emergence of a sub-photospheric, current-neutralized magnetic flux rope into the solar atmosphere. We find that a strong deviation from current neutralization develops simultaneously with the onset of significant flux emergence into the corona, accompanied by the development of substantial magnetic shear along the active region's polarity inversion line. After the region has formed and flux emergence has ceased, the strong magnetic fields in the region's center are connected solely by direct currents, and the total direct current is several times larger than the total return current. These results suggest that active regions, the main sources of coronal mass ejections and flares, are born with substantial net currents, in agreement with recent observations. Furthermore, they support eruption models that employ pre-eruption magnetic fields containing such currents.

    Objective: the aim of this study was to analyze chest CT scans of patients with thoracic textiloma. Methods: this was a retrospective study of 16 patients (11 men and 5 women) with surgically confirmed thoracic textiloma. The chest CT scans of those patients were evaluated by two independent observers, and discordant results were resolved by consensus. Results: the majority (62.5%) of the textilomas were caused by previous heart surgery. The most common symptoms were chest pain (in 68.75%) and cough (in 56.25%). In all cases, the main tomographic finding was a mass with regular contours and borders that were well-defined or partially defined. Half of the textilomas occurred in the right hemithorax and half occurred in the left. The majority (56.25%) were located in the lower third of the lung. The diameter of the mass was ≤ 10 cm in 10 cases (62.5%) and > 10 cm in the remaining 6 cases (37.5%). Most (81.25%) of the textilomas were heterogeneous in density, with signs of calcification, gas, radiopaque marker, or sponge-like material. Peripheral expansion of the mass was observed in 12 (92.3%) of the 13 patients in whom a contrast agent was used. Intraoperatively, pleural involvement was observed in 14 cases (87.5%) and pericardial involvement was observed in 2 (12.5%). Conclusions: it is important to recognize the main tomographic aspects of thoracic textilomas in order to include this possibility in the differential diagnosis of chest pain and cough in patients with a history of heart or thoracic surgery, thus promoting the early identification and treatment of this postoperative complication.

    Acromegaly involves cardiovascular complications mostly due to the presence of hypertension, diabetes and atherosclerosis. However the appearance of cardiac decompensation and arrhythmias in the absence of predisposing factors tends to support the hypothesis of a specific myocardiopathy caused by excess GH. In order to assess the existence and course of subclinical cardiac alterations, 8 acromegaly patients were examined: 4 males and 4 females aged 31-56 with GH levels of 24-70 ng/ml (M + CD X 47 +/- 16) and no cardiovascular symptoms. One of the patients had moderate hypertension and 2 reduced glucose tolerance. The basal ECG showed sporadic ventricular extrasystoles in 2 cases and alterations compatible with left ventricular hypertrophy in another, while the effort ECG produced an asymptomatic depression of the ST segment in the hypertensive patient. The chest X-ray was normal in all cases. The echocardiography study investigated: the thickness of the interventricular septum (IVS = 13.9 +/- 2.8 mm), the thickness of the posterior wall of the left ventricle (LPW = 10.6 +/- 2.9 mm), the septum/posterior wall ratio (IVS/LPW = 1.3 +/- 0.2 the diastolic diameter (DD = 15.4 +/- 11.4 mm), the fraction of shortening (FS = 39.1 +/- 14.5%), the ejection fraction (EF = 64.1 +/- 18.4%) and revealed asymmetrical septal hypertrophy in 3 cases, concentric hypertrophy in another two. In two cases the DD and EF were distinctly altered. The patients were re-examined 2-4 years after surgical or radiation treatment. GH levels (M +/- SD = 10.3 +/- 10.1 ng/ml) were normal in 4 cases and still high, though lower in another two. The remaining two patients had borderline GH levels with high Sm-C. The ECG and chest X-ray were unchanged while echocardiography revealed a significant deterioration in heart function as far as DD (56.4 +/- 10.8 mm, p less than 0.05) were concerned with frankly pathological results in 4 and 3 cases respectively. These data confirm the view that most acromegalic

    Full Text Available Introduction. Acute respiratory infections are the most common infections in the human population. Among them, virus infections, especially those caused by influenza viruses, have an important place. Type A influenza. Type A influenza virus caused three epidemics during the last century. A high percetage of deceased in pandemics of 1918, and 1919 were young, healthy persons, with many of the deaths due to an unusually severe, hemorrhagic pneumonia. At the end of 2003, and the beginning of 2004, an epidemic emerged in South East Asia of poultry influenza caused by animal (avian virus. Later it spread to the human population, with a high death rate of 73% and with a possibility of interhuman transmission. This review article provides an overview of the clinical manifestations, laboratory findings and chest radiographs. Apart from the symptomatic and supportive therapy, there are antiviral drugs and corticosteriods. Conclusion. The use of vaccine containing subtypes of virus hemagglutinins and neuraminidase from an influenza virus currently infecting the population has a great importance. .

  13. Factors Affecting Current and Future CSA Participation

    Full Text Available Community Supported Agriculture (CSA is one of the widely used direct marketing strategies for small- and midsized farmers. CSA programs are an important option for sustainable production and consumption. It helps growers generate income (improve financial security and consumers obtain fresh local foods. Sustaining and growing CSA participation is critical in order to continue enjoying these benefits. We used a national online survey in conjunction with discrete choice models to investigate the impact of demographic characteristics, lifestyle preferences, and different information outlets on the probability that a consumer is or will become a CSA member. The results indicate that the factors affecting current and future CSA participation differ substantially. While none of the demographic characteristics has a significant impact on current CSA participation, some of them significantly affect the probability that a consumer will become a CSA member in the future. Lifestyle preferences have a significant impact on current and future CSA participation. Although none of the information outlets examined affect current CSA participation, word-of-mouth and online sources significantly influence the probability that a consumer will join a CSA program in the future. These findings may have important implications for policy makers’ and CSA farm managers’ efforts to sustain future CSA development.

    2015-04-01

    Peer support groups have a long history and have been shown to improve health outcomes. With the increasing familiarity with online social networks like Facebook and ubiquitous access to the Internet, online social support networks are becoming popular. While studies have shown the benefit of these networks in providing emotional support or meeting informational needs, robust data on improving outcomes such as a decrease in health services utilization or reduction in adverse outcomes is lacking. These networks also pose unique challenges in the areas of patient privacy, funding models, quality of content, and research agendas. Addressing these concerns while creating patient-centred, patient-powered online support networks will help leverage these platforms to complement traditional healthcare delivery models in the current environment of value-based care.

  18. THE EVOLUTION OF ECONOMIC GLOBALIZATION DURING THE CURRENT GLOBAL CRISIS

    2013-12-01

    Full Text Available The current economic crisis constitutes a serious test for the process of globalization. The purpose of this study is to analyze the influence of the current global crisis on economic globalization. To assess the impact of the current crisis on economic globalization, this paper examines the KOF Index of Globalization, before and during the crisis. The findings generally support the idea that economic globalization has been, in fact, weakened, after the onset of the current crisis. However, there is evidence that suggest that economic globalization has resumed the upward trend that characterized it before the crisis. Despite the fact the global crisis has shaken the process of globalization, we cannot talk of an end of globalization, as some predictions have indicated.

  2. Bioartificial Liver Support

    Directory of Open Access Journals (Sweden)

    Vincent G Bain

    2001-01-01

    Full Text Available Bioartificial liver support has been increasingly the focus of both basic and clinical research in an attempt to replicate the multiplicity of normal liver function. The concept is attractive because, if it is effective, patients with acute liver failure may be supported until native liver regeneration occurs or, by optimizing their condition, until liver transplantation is possible. Current bioartificial liver support systems utilize primary porcine hepatocytes or transformed human hepatocytes, which are housed within a bioreactor, through which the patient's blood or plasma is pumped in an extracorporeal circuit. The optimal source for the hepatocytes is an area of debate; however, a genetically engineered cell line may provide optimal function. Novel three-dimensional matrices that anchor the hepatocytes are being designed to mimic architectural features of the normal liver. Large multicentre, randomized, controlled trials are ongoing following several pilot studies. Serious side effects such as hemodynamic instability and immune reactions have been infrequent. Much controversy, however, surrounds the issue of possible transmission of pig endogenous retrovirus to humans, and current trials are being carefully monitored. Bioartificial liver support is a promising technology, and the results of current and planned studies are awaited with great interest.

    Amber, Ian Blake; Clark, Brian J; Greene, Gary Stuart

    2013-01-01

    Pigmented villonodular synovitis (PVNS) is an uncommon entity, which has the potential to cause severe pain. The gold standard for evaluation is MRI, and previous PET findings associated with PVNS have only been documented in the setting of concurrent malignancy. In the setting of recurrent disease, PET is being used to evaluate prebiological and postbiological treatment responses. Recurrent PVNS demonstrates greater hypermetabolic activity than previously documented, supporting the case as a potential mimic of malignant/metastatic disease. Post-treatment evaluations demonstrate decreased metabolic activity, which suggests response to treatment. This behaviour further supports the contention that there is a neoplastic origin to PVNS.

    Studies performed during 1983-1986 on the ring current, the injection boundary model, and the radiation belts are discussed. The results of these studies yielded the first observations on the composition and charge state of the ring current throughout the ring-current energy range, and strong observational support for an injection-boundary model accounting for the origins of radiation-belt particles, the ring current, and substorm particles observed at R less than about 7 earth radii. In addition, the results have demonstrated that the detection of energetic neutral atoms generated by charge-exchange interactions between the ring current and the hydrogen geocorona can provide global images of the earth's ring current and its spatial and temporal evolution.

    2005-06-15

    The Keystone Center convened and facilitated a year-long Dialogue on "Regional Transmission Projects: Finding Solutions" to develop recommendations that will help address the difficult and contentious issues related to expansions of regional electric transmission systems that are needed for reliable and economic transmission of power within and across regions. This effort brought together a cross-section of affected stakeholders and thought leaders to address the problem with the collective wisdom of their experience and interests. Transmission owners sat at the table with consumer advocates and environmental organizations. Representatives from regional transmission organizations exchanged ideas with state and federal regulators. Generation developers explored common interests with public power suppliers. Together, the Dialogue participants developed consensus solutions about how to begin unraveling some of the more intractable issues surrounding identification of need, allocation of costs, and reaching consensus on siting issues that can frustrate the development of regional transmission infrastructure. The recommendations fall into three broad categories: 1. Recommendations on appropriate institutional arrangements and processes for achieving regional consensus on the need for new or expanded transmission infrastructure 2. Recommendations on the process for siting of transmission lines 3. Recommendations on the tools needed to support regional planning, cost allocation, and siting efforts.

  10. Knowledge translation of research findings

    Directory of Open Access Journals (Sweden)

    Grimshaw Jeremy M

    2012-05-01

    Full Text Available Abstract Background One of the most consistent findings from clinical and health services research is the failure to translate research into practice and policy. As a result of these evidence-practice and policy gaps, patients fail to benefit optimally from advances in healthcare and are exposed to unnecessary risks of iatrogenic harms, and healthcare systems are exposed to unnecessary expenditure resulting in significant opportunity costs. Over the last decade, there has been increasing international policy and research attention on how to reduce the evidence-practice and policy gap. In this paper, we summarise the current concepts and evidence to guide knowledge translation activities, defined as T2 research (the translation of new clinical knowledge into improved health. We structure the article around five key questions: what should be transferred; to whom should research knowledge be transferred; by whom should research knowledge be transferred; how should research knowledge be transferred; and, with what effect should research knowledge be transferred? Discussion We suggest that the basic unit of knowledge translation should usually be up-to-date systematic reviews or other syntheses of research findings. Knowledge translators need to identify the key messages for different target audiences and to fashion these in language and knowledge translation products that are easily assimilated by different audiences. The relative importance of knowledge translation to different target audiences will vary by the type of research and appropriate endpoints of knowledge translation may vary across different stakeholder groups. There are a large number of planned knowledge translation models, derived from different disciplinary, contextual (i.e., setting, and target audience viewpoints. Most of these suggest that planned knowledge translation for healthcare professionals and consumers is more likely to be successful if the choice of knowledge

    The current study examined the impact of size of social network on subjective well-being of elderly, mainly focused on confirmation of the mediator role of perceived social support. The results revealed that both size of social network and perceived social support were significantly correlated with subjective well-being. Structural equation modeling indicated that perceived social support partially mediated size of social network to subjective well-being. The final model also revealed significant both paths from size of social network to subjective well-being through perceived social support. The findings extended prior researches and provided valuable evidence on how to promote mental health of the elderly.

  12. Optimal Current Transfer in Dendrites

    Bird, Alex D.

    2016-01-01

    Integration of synaptic currents across an extensive dendritic tree is a prerequisite for computation in the brain. Dendritic tapering away from the soma has been suggested to both equalise contributions from synapses at different locations and maximise the current transfer to the soma. To find out how this is achieved precisely, an analytical solution for the current transfer in dendrites with arbitrary taper is required. We derive here an asymptotic approximation that accurately matches results from numerical simulations. From this we then determine the diameter profile that maximises the current transfer to the soma. We find a simple quadratic form that matches diameters obtained experimentally, indicating a fundamental architectural principle of the brain that links dendritic diameters to signal transmission.

  13. Directed Current Without Dissipation: Reincarnation of a Maxwell-Loschmidt Demon

    Science.gov (United States)

    Goychuk, Igor; Haenggi, Peter

    We investigate whether for initially localized particles a directed current in rocked periodic structures is possible in absence of a dissipative mechanism. With a pure Hamiltonian dynamics the breaking of Time-Reversal-Invariante presents anecessary condition to find nonzero current values. Numerical studies are presented for the classical Hamiltonian dynamical case. These support the fact that indeed a finite current does occur when a time-reversal symmetry-breaking signal, such as a harmonic mixing signal, is acting. To gain analytical insight we consider the coherent driven quantum transport in a one-dimensional tight-binding lattice. Here, a finite coherent current is absent for initially localized preparations; it emerges, however, when the initial preparation (with zero initial current) possesses finite coherence. The presence of phase fluctuations will eventually kill any finite current, thereby rendering the nondissipative currents a transient phenomenon.

    Primary and secondary school Pantovčak is an innovative school in downtown Zagreb, Croatia. The school is involved in many projects concerning STEM education. Pollution! Find a STEM solution! is a two year long cross-curricular project that grew out of identified need to develop STEM and ICT skills more. Pisa results make evident that students' knowledge is poor and motivation for math and similar subjects is low. Implying priorities of European Commission, like e-learning, raises motivation and also develops basic skills and improves knowledge in science, math, physic, ICT. Main objectives are to increase students' interest in STEM education and careers and introduce them to all available new trends in technology, engineering and science in their region by visiting clean technology industries and strengthening links with them, to introduce some future digital jobs and prepare students for rapid technological changes by integrating ICT into classroom practice more, to highlight the importance of global environmental issues and improve the knowledge in the areas of sustainable development and renewable energy, to develop collaborative partnership between schools and the wider community in formal, non-formal and informal learning, to support multilingualism by publishing Open Educational Resources in 8 different languages and to strengthen the professional profile of the teaching profession. The project brings together 231 teachers and 2729 students from five different European countries in learning to think globally and work on activities that contribute to the community's well-being. There are altogether 33 activities, divided in 4 categories. STEM activities are focused on students building the devices for measuring air, light and noise pollution in their school and homes. They use the scientific method to analyze the data and compare the results with their peers to find a solution. Eskills, digital literacy and digital jobs are focused on introducing career

    Holometry studies of automotive body and powertrain components have become a very useful high resolution test methodology to knowledgeable Ford engineering personnel. Current examples of studies that represent the static or dynamic operational conditions of the automotive test component are presented. Continuous wave laser holometry, computer aided holometry (CAH) and pulsed laser holometry were the holometric techniques used to study the following subjects: (1) body in prime (BIP) vibration modes, (2) transmission flexplate stud-torque converter deformation due to engine torque pulses, (3) engine cylinder head and camshaft support structure deformation due to cylinder pressure and (4) engine connecting rod/cap lift-off. Static and dynamic component loading and laboratory techniques required to produce usable and valid test results are discussed along with possible conclusions for the engineering concerns.

    This study considers the physical phenomenon whereby wires may fragment in the solid state when subject to a sufficiently high pulsed electric current. A mathematical model is constructed within continuum mechanics which considers both Lorentz force and thermal mechanisms for the creation of stress waves in a wire. Previous studies are extended by including the skin effect, that is allowing for the diffusion of current density across the wire, and also investigating the influence of current risetime. Axisymmetric solutions are sought for rigid-lubricated, clamped, and free wire ends. Analytical solutions are obtained for the case of rigid-lubricated wire ends, while for the other cases the governing equations are solved numerically using an application-specific explicit finite-difference scheme, which is staggered in time and space. The inclusion of the skin effect leads to significant qualitative and quantitative differences in results. For example, in some cases we find tension in the longitudinal (τzz) stress component, which experiments suggest to be responsible for the fragmentation process, while the uniform-current model predicts compression. In most cases, the inclusion of the skin effect leads to higher peak tensile τzz stresses. Some understanding of the present results is gained with reference to analytical quasistatic solutions. Stresses generated by the Lorentz force mechanism are found to be more sensitive than those generated by the thermal mechanism to the current risetime. In both cases axial stresses increase with decreasing current risetime. Despite the differences in the results obtained with the inclusion of the skin effect, our results support the broad conclusions of the uniform-current model results; the largest stresses are found at the clamps for a wire with clamped ends, while the largest stresses in a wire with free ends are generated by the thermal mechanism and are located at the center of the wire.

    Eighteen feet made of stainless steel will support the barrel ATLAS detector in the cavern at Point 1. In total, the ATLAS feet system will carry approximately 6000 tons, and will give the same inclination to the detector as the LHC accelerator. The installation of the feet is scheduled to finish during January 2004 with an installation precision at the 1 mm level despite their height of 5.3 metres. The manufacture was carried out in Russia (Company Izhorskiye Zavody in St. Petersburg), as part of a Russian and JINR Dubna in-kind contribution to ATLAS. Involved in the installation is a team from IHEP-Protvino (Russia), the ATLAS technical co-ordination team at CERN, and the CERN survey team. In all, about 15 people are involved. After the feet are in place, the barrel toroid magnet and the barrel calorimeters will be installed. This will keep the ATLAS team busy for the entire year 2004.

    While the deleterious consequences of long hours of work for individuals, families and communities have previously been documented, the assumption that long hours are necessary to get the work done, especially in a world where speed is becoming increasingly critical to corporate success, has prompted little challenge. So Leslie Perlow, an assistant professor of business at the University of Michigan, Ann Arbor, set out to explore the necessity for the seemingly endless workdays that so many postindustrial settings require. Her study of a group of software engineers at a Fortune 500 company--identified only as the Ditto Corp--is detailed in her book, Finding Time: How Corporations, Individuals, and Families Can Benefit from New Work Practices (Cornell University Press, 1997). Perlow's research reveals a "sad and all too common tale" of workers harried by competing demands, frequent interruptions and shifting deadlines. To meet the firm's expectations, the engineers she studied sacrificed home life, focused on individual tasks to the detriment of group goals and, in many cases, eventually lost any enthusiasm they'd had for working for the company. There has been some recognition that stress and burnout may be bad for a corporation as employees become less committed, decide to leave or get fired and that this kind of turnover can hurt the firm in the longer term. But Perlow documented the additional, and quite significant, shorter-term costs to the corporation of the current way of using time at work. What she found was a "vicious time cycle:" Time pressures led to a crisis mentality, which led to "individual heroics." That is, I'll do whatever it takes to do my job--even if it means interrupting you while you try to do yours. For the engineers Perlow studied, the lack of helping, the constant interruptions and the perpetual crises--clearly illustrated by the daily log that appears on page 34--made it harder to develop products. Ultimately, they worked long hours to

    In this report, we present computed tomographic findings of colonic trichuriasis. The patient was a 75-year-old man who complained of abdominal pain, and weight loss.Diagnosis was achieved by colonoscopic biopsy. Abdominal computed tomography showed irregular and nodular thickening of the wall of the cecum and ascending colon.Although these findings are nonspecific, they may be one of the findings of trichuriasis. These findings, confirmed by pathologic analysis of the biopsied tissue and KatoKatz parasitological stool flotation technique, revealed adult Trichuris. To our knowledge, this is the first report of colonic trichuriasis indicated by computed tomography.

    1999-04-01

    Clinicians have two types of prosthetic sockets for patients with a transfemoral amputation: the quadrilateral socket introduced in the 1950s and the ischial containment socket introduced in the 1980s. For many years, the quadrilateral socket was acceptable to clinicians and patients alike. With the introduction of the ischial containment socket claims were made that the quadrilateral socket had been inadequate from its inception. It also was claimed that the ischial containment design was the answer to all problems than patients with transfemoral amputations may have. Unfortunately, there is only one scientific study that lends any support to claims of the ischial containment socket's superiority and its findings are limited. Still, clinicians must make recommendation and prescription decisions daily regarding what is best for their patients. There are two acceptable socket designs for patients with transfemoral amputations. Experience with both supports the concept that they have more similarities than differences and that each has a legitimate place in the treatment of patients with transfemoral amputations. A comprehensive understanding of each socket design and its biomechanical intentions is essential for successful clinical application and treatment of patients with amputations.

    Sensor technology, which benefits from high temporal measuring resolution, real-time data transfer and high spatial resolution of sensor data that shows in-field variations, has the potential to provide added value for crop production. The present paper explores how sensors and sensor networks have been utilised in the crop production process and what their added-value and the main bottlenecks are from the perspective of users. The focus is on sensor based applications and on requirements that users pose for them. Literature and two use cases were reviewed and applications were classified according to the crop production process: sensing of growth conditions, fertilising, irrigation, plant protection, harvesting and fleet control. The potential of sensor technology was widely acknowledged along the crop production chain. Users of the sensors require easy-to-use and reliable applications that are actionable in crop production at reasonable costs. The challenges are to develop sensor technology, data interoperability and management tools as well as data and measurement services in a way that requirements can be met, and potential benefits and added value can be realized in the farms in terms of higher yields, improved quality of yields, decreased input costs and production risks, and less work time and load.

    2017-02-01

    Scaling properties of a two-dimensional (2d) plasma physical current-sheet simulation model involving a full set of magnetohydrodynamic (MHD) equations with current-dependent resistivity are investigated. The current sheet supports a spatial magnetic field reversal that is forced through loading of magnetic flux containing plasma at boundaries of the simulation domain. A balance is reached between loading and annihilation of the magnetic flux through reconnection at the current sheet; the transport of magnetic flux from boundaries to current sheet is realized in the form of spatiotemporal avalanches exhibiting power-law statistics of lifetimes and sizes. We identify this dynamics as self-organized criticality (SOC) by verifying an extended set of scaling laws related to both global and local properties of the current sheet (critical susceptibility, finite-size scaling of probability distributions, geometric exponents). The critical exponents obtained from this analysis suggest that the model operates in a slowly driven SOC state similar to the mean-field state of the directed stochastic sandpile model. We also investigate multiscale correlations in the velocity field and find them numerically indistinguishable from certain intermittent turbulence (IT) theories. The results provide clues on physical conditions for SOC behavior in a broad class of plasma systems with propagating instabilities, and suggest that SOC and IT may coexist in driven current sheets which occur ubiquitously in astrophysical and space plasmas.

    Tendinopathy is characterized by pain in the tendon and impaired performance sometimes associated with swelling of the tendon. Its diagnosis is usually clinical but ultrasonography and magnetic resonance imaging can refine the diagnosis. Tendinopathy is highly prevalent and is one of the most frequently self reported musculoskeletal diseases in physical workers and sports people. Nevertheless, it is very difficult to carry out general epidemiologic studies on tendinopathy because of the varying sports cultures and sports habits in different countries. The aetiology of tendinopathy seems to be multi-factorial, involving intrinsic and extrinsic factors. The role of inflammation is still debated but the absence of inflammatory cells does not mean that inflammatory mediators are not implicated. Different theories have been advanced to explain pain and chronicity mechanisms, but these mechanisms remain largely unknown. “Conventional ”treatments are generally employed empirically to fight pain and inflammation but they do not modify the histological structure of the tendon. However, these treatments are not completely satisfactory and the recurrence of symptoms is common. Currently, eccentric training remains the treatment of choice for tendinopathy, even though some studies are contradictory. Moreover, many interesting new treatments are now being developed to treat tendinopathy, but there is little evidence to support their use in clinical practice. Key points The word “tendinopathy ”is the correct term for the clinical diagnosis of pain accompanied by impaired performance, and sometimes swelling in the tendon. The aetiology of tendinopathy seems to be a multi-factorial process, involving promoting factors that are intrinsic or extrinsic, working either alone or in combination. US (with color Doppler) and MRI are usually prescribed when tendinopathy is unresponsive to treatment and entails lingering symptoms. Eccentric training is currently considered to be the

    Research indicates that greater involvement in activities is essential for successful aging. The purpose of the current study is to examine a construct that motivates involvement in activities-finding interests in life. In the process, we also show how involvement in religion may help promote interests. In order to examine these issues, a conceptual model is tested that contains the following core hypotheses: (1) older people who go to church more often will be more likely to have stronger God-mediated control beliefs (i.e., the belief that God works together with people to resolve problems and reach desired goals); (2) older adults with a stronger sense of God-mediated control will be more likely to find things in life that are interesting; and (3) older individuals with more interests experience a greater sense of self-worth over time. Findings from a nationwide survey provide support for the key relationships described above. © The Author(s) 2013.

    Scrotal sonography is a valuable tool for assessing the testis and surrounding structures, and has become the imaging modality of choice for evaluation of the scrotum. Scrotal sonography is also helpful for differentiating cystic from slid mass and testicular from extratesticular mass, but is sometimes difficult in differentiating malignant tumor from various benign conditions such as epidermoid cyst, focal orchitis, testicular hematoma, and abscess. We demonstrate the sonographic findings of the various testicular mass, and correlation with pathologic findings.

    Femoroacetabular impingement syndrome (FAI) is a pathologic entity which can lead to chronic symptoms of pain, reduced range of motion in flexion and internal rotation, and has been shown to correlate with degenerative arthritis of the hip. History, physical examination, and supportive radiographic findings such as evidence of articular cartilage damage, acetabular labral tearing, and early-onset degenerative changes can help physicians diagnose this entity. Several pathologic changes of the femur and acetabulum are known to predispose patients to develop FAI and recognition of these findings can ultimately lead to therapeutic interventions. The two basic mechanisms of impingement - cam impingement and pincer impingement - are based on the type of anatomic anomaly contributing to the impingement process. These changes can be found on conventional radiography, MR imaging, and CT examinations. However, the radiographic findings of this entity are not widely discussed and recognized by physicians. In this paper, we will introduce these risk factors, the proposed supportive imaging criteria, and the ultimate interventions that can help alleviate patients' symptoms. (orig.)

    The fungus aspergillus can cause a variety of pulmonary disorders. Aspergilloma is a noninvasive aspergillus colonization of virtually any type of preexisting pulmonary cavity or cystic space. Invasive pulmonary aspergillosis is serious, usually fatal infection in patients being treated with immunosuppressants or who have chronic debilitating disease. Allergic bronchopulmonary aspergillosis is characterized clinically by asthma, blood and sputum eosinophilia and positive immunologic reaction to aspergillus antigen. Awareness of the radiographic and CT findings of pulmonary aspergillosis is important in making the diagnosis of aspergillus-caused pulmonary disorders. In this pictorial essay, we illustrated various radiological findings of pulmonary aspergillosis focused on CT findings correlated with gross pathologic specimens.

    The describe the radiologic findings of granulomatous mastitis of the breast. This study included 19 patients (age range: 22 to 56 years; mean 37 years) with 22 lesions that were pathologically confirmed as having granulomatous mastitis. All the patients underwent a breast ultrasonography and 13 patients underwent a mammography. The results of the mammography revealed focal asymmetry (n = 9), multiple ill-defined isodense nodules (n 2), ill-defined nodular density on craniocaudal view (n = 1), and unremarkable finding (n = 1). The sonographic findings included continuous or discontinuous multiple tubular and nodular low echoic lesions (n = 7), ill-defined heterogeneously low echoic lesion (n = 5), irregular-shaped, ill-defined low echoic mass (n = 4), fluid collection with internal floating materials suggesting the presence of an abscess (n = 4), ill-defined heterogeneously low echoic lesion and abscess (n = 1), and multiple ill-defined nodules (n = 1). In the case of granulomatous mastitis, the mammography results indicate a lack of specificity between normal findings and focal asymmetry. The sonographic findings indicate that ill-defined heterogeneously low echoic lesions or irregular shaped, ill-defined low echoic masses are difficult to differentiate from breast cancer. The sonographic findings of abscesses indicate a difficulty in differentiating them from cases of pyogenic mastitis. However, multiple tubular and nodular low echoic lesions, especially with a continuous appearance, should point to granulomatous mastitis, and is helpful in its differential diagnosis and treatment.

    Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects--its history, applications, and ongoing quest to find near-Earth objects before they find us.

    2000-01-01

    To define the imaging patterns of xanthogranulomatous pyelonephritis (XGP). The demographic, clinical, and imaging findings of 21 cases of pathologically proven XGP in 20 patients (bilateral in one) were evaluated. The findings of ultrasonography and CT were retrospectively evaluated with regard to distribution and extent of the disease, kidney size, the presence of calculi, hydronephrosis, and renal function. The findings were assessed by two radiologists, who established a consensus. Imaging and pathologic findings were compared. Sixteen of the 20 patients were female, and 19 were adults. Their age ranged from 3 to 16 (mean, 45) years. In all patients except one, the disease was unilateral (right: left =3D 13 :16). In one patient, XGP was bilateral, and there were thus 21 cases. Seventeen (81%) of these were diffuse, and four (19%) were focal; extrarenal extension occurred in 13 cases (62%), among which ipsilateral pleural effusion was noted in two. The kidney was enlarged diffusely in 12 cases (57%), and focally in three (14%); urinary calculi were present in 16 cases (76%), with staghorn calculi in four of these; and hydronephrosis occurred in 17 (81%). Impairment of ipsilateral renal function was noted in 13 cases (62%). Clinical findings of inflammation such as fever, pyuria, bacteriuria, or leucocytosis were noted in all patients. In addition to nephromegaly, renal function impairment, and urinary obstruction due to calculi, which are typical features of XGP, the condition may also show variable imaging findings. If the images obtained in the case of a middle-aged woman with clinical findings of urinary infection are atypical, we believe that XGP should be included in the differential diagnosis. (author)

  3. Acoustoelectric current for composite fermions

    Science.gov (United States)

    Bergli, J.; Galperin, Y. M.

    2001-07-01

    The acoustoelectric current for composite fermions in a two-dimensional electron gas (2DEG) close to the half-filled Landau level is calculated in the random phase approximation. The Boltzmann equation is used to find the nonequilibrium distribution of composite fermions to second order in the acoustic field. It is shown that the oscillating Chern-Simons field created by the induced density fluctuations in the 2DEG is important for the acoustoelectric current. This leads to a violation of the Weinreich relation between the acoustoelectric current and acoustic intensity. The deviations from the Weinreich relation can be detected by measuring the angle between the longitudinal and the Hall components of the acoustoelectric current. This departure from the Weinreich relation gives additional information on the properties of the composite fermion fluid.

    To evaluate the MR findings of brain damage in cerebral palised patients and to correlate it with gestational age and the time of damage. A retrospective analysis was performed in 40 patients who underwent MR scanning for evaluation of brain lesion in clinically diagnosed cerebral palsy. Authors classified the patients into two groups as premature and full-term and compared MR findings of the two groups. Abnormal MR findings were noted in 28 cases (70%). Five out of 6 patients who had been born prematurely showed isolate periventricular white matter lesions. Twenty-three out of 34 patients who had been born at full-term showed abnormal MR findings. Of these 23 patients, migration anomalies in 7 patients, isolate periventricular white matter lesions in 3 patients, and other combined periventricular subcortical white matter and deep gray matter lesions in 14 patients were seen. At least, 10 patients(43%) of full term group showed abnormal MRI findings reflecting intrauterine brain damage and all 5 patients of premature group showed isolate periventricular white matter lesions suggesting immaturity of brain. MRI is thought to be very useful in the assessment of brain damage for the patients with cerebral palsy by recognizing the location of the lesion and estimating the time of damage.

    We have experienced 14 cases of cryptococcal meningitis in the last 6 years. Their neurological signs, CT findings, and prognoses were studied. They fall into three types: the brain-stem-encephalitis type, the cortical-encephalitis type, and the meningitis type, according to the clinical course. The first type (6 cases) revealed mainly cerebellar signs, eye-movement damage, and so forth. The second type (5 cases) demonstrated ''Personality'' changes, chiefly aphasia. The third type (5 cases) did not show any focal signs. Prognosis of the brain-stem-encephalitis type was very poor, with a 50% mortality rate. In the survivors, also, clinical signs did not disappear for a long time. Repeated CT was performed in 13 among the 14 cases; abnormal CT findings were revealed in 5 cases because of cryptococcal infection. Granuloma shadow and ventriculitis shadow were observed in 3 cases each. These abnormal findings disappeared upon treatment except in one case. The clinical signs are not completely related with the CT finding, but it is useful that the site which has been infiltrated by the cryptococcus can be observed. Abnormal CT findings were observed in the 4 cases of the brain-stem-encephalitis type among the 5 abnormal cases. It is very useful to know the severity of the condition.

    Full Text Available Nan Zeng, Zan Gao College of Education and Human Development, School of Kinesiology, University of Minnesota, Minneapolis, MN, USA Abstract: Although exergaming has been used as a physical activity modality among various populations, the evidence regarding its effectiveness on health-related outcomes in overweight/obese individuals remains unclear. The current study systematically reviewed literature and summarized findings of exergame-based interventions in overweight/obese populations with the goal of clarifying the current perspectives on exergaming and obesity. The initial search yielded 202 articles from six databases; 12 studies were included after evaluating for inclusion criteria and removing duplicates. Among these studies, seven were randomized controlled trials, two were control trials, and three were comparison studies. Overall, exergaming has the potential to attenuate weight gain and shows promise when used for physical activity and physical fitness promotion. Further, exergame play is positively associated with psychological well-being, but its effects on physiological outcomes are inconclusive. Finally, effects of exergaming on energy intake are not clear. Existing evidence supports that exergaming may elicit some health benefits in people who are overweight or/and obese. The limited number of available randomized controlled trials, however, restrict the ability to draw a conclusion that exergaming can trigger a change in all health-related outcomes. More research is warranted to make definitive conclusions regarding the effects of exergaming on health-related outcomes in such populations.

    Solitary pulmonary nodule represents 0.2% of incidental findings in routine chest X-ray images. One of the main diagnoses includes lung cancer in which small-cell subtype has a poor survival rate. Recently, a new classification has been proposed including the very limited disease stage (VLD stage) or T1-T2N0M0 with better survival rate, specifically in those patients who are treated with surgery. However, current recommendations postulate that surgery remains controversial as a first-line treatment in this stage. We present the case of a 46-year-old female referred to our hospital with a preoperative diagnosis of a solitary pulmonary nodule. On initial approach, a biopsy revealed a small cell lung cancer. She received multimodal therapy with surgery, chemotherapy, and prophylactic cranial irradiation and is currently alive without recurrence on a 2-year follow-up. PMID:22345914

    Primary hepatic sarcomas are rare tumors that are difficult to diagnose clinically. Different primary hepatic sarcomas may have different clinical, morphologic, and radiological features. In this pictorial review, we summarized computed tomography (CT) findings of some relatively common types of hepatic sarcomas, including angiosarcoma, epithelioid hemangioendothelioma (EHE), liposarcoma, undifferentiated embryonal sarcoma (UES), leiomyosarcoma, malignant fibrous histiocytoma (MFH), and carcinosarcoma (including cystadenocarcinosarcoma). To our knowledge, hepatic cystadenocarcinosarcoma has not been described in the English literature. The CT findings in our case are similar to that of cystadenocarcinoma, a huge, multilocular cystic mass with a large mural nodule and solid portion. The advent of CT has allowed earlier detection of primary hepatic sarcomas as well as more accurate diagnosis and characterization. In addition, we briefly discuss the MRI findings and diagnostic value of primary hepatic sarcomas. (orig.)

    Skiing and hiking outside the boundaries remains an attractive wilderness activity despite the danger of avalanches. Avalanches occur on a relatively frequent basis and may be devastating. Musculoskeletal radiologists should be acquainted with these injuries. Fourteen avalanche victims (11 men and 3 women; age range 17-59 years, mean age 37.4 years) were air transported to a high-grade trauma centre over a period of 2 years. Radiographs, CT and MR images were prospectively evaluated by two observers in consensus. Musculoskeletal findings (61%) were more frequent than extraskeletal findings (39%). Fractures were most commonly seen (36.6%), involving the spine (14.6%) more frequently than the extremities (9.8%). Blunt abdominal and thoracic trauma were the most frequent extraskeletal findings. A wide spectrum of injuries can be found in avalanche victims, ranging from extremity fractures to massive polytrauma. Asphyxia remains the main cause of death along with hypoxic brain injury and hypothermia. (orig.)

    To review the simple radiographic and sonographic findings in infants with neonatal sepsis. We retrospectively analyzed simple chest and abdominal radiographs, and brain sonograms in 36 newborn infants (preterm : term=23 :13). With neonatal sepsis diagnosed by blood culture and clinical manifestations. Pulmonary parenchymal infiltrate excluding respiratory distress syndrome and pulmonary edema or atelectasis was found in 22 infants (61%). Paralytic ileus, hepatosplenomegaly, and necrotizing enterocolitis were present in 18(50%), 9(25%), and 1(3%) infants, respectively, while skeletal changes suggesting osteomyelitis were found in three. Brain sonography was performed in 29 infants and in four, abnormalities were seen ; these comprised three germinal matrix hemorrhages and one intraparenchymal hemorrhage. In six patients(17%) radiologic examinations revealed no abnormality. In patients with neonatal sepsis, pulmonary infiltrates and paralytic ileus were common abnormalities. Although these were nonspecific, radiologic findings may be used to supplement clinical and laboratory findings in diagnosing neonatal sepsis and planning its treatment.

Of 14 cases, 10 cases were associated with myasthenia gravis, and 7 of these 10 cases were 3rd to 5th decades females. Among 10 cases with myasthenia gravis. 5 cases were thymic hyperplasia, 1 case was benign thymoma, 2 cases were malignant thymoma, and 2 cases were normal thymus. 3. All 5 thymic hyperplasia were associated with myasthenia gravis. CT findings of thymic hyperplasia were normal in 4 cases and increased lobe thickness in 1 case. 4. Of 4 cases of benign thymoma, only 1 case was associated with myasthenia gravis, and all 4 cases were positive findings in CT scan. CT findings of benign thymoma were round or oval soft tissue mass in anterior mediastinum, and 1 case had punctuate calcifications. 5. Of 2 cases of malignant thymoma, all 2 cases were associated with myasthenia gravis and positive findings in CT scan. CT findings of malignant thymoma were anterior mediastinal soft tissue mass with obliteration of the normal fat planes surrounding great vessels. SVC compression, and pleural tumor implants. 6. CT yielded significant diagnostic information of differential diagnosis between thymoma and thymoma hyperplasia in myasthenia gravis patients. Also CT was highly sensitive test in detection of thymoma and determined the extent and invasiveness of thymoma.

    The design and mass cost of a starship and its life support system are investigated. The mission plan for a multi generational interstellar voyage to colonize a new planet is used to describe the starship design, including the crew habitat, accommodations, and life support. Only current technology is assumed. Highly reliable life support systems can be provided with reasonably small additional mass, suggesting that they can support long duration missions. Bioregenerative life support, growing crop plants that provide food, water, and oxygen, has been thought to need less mass than providing stored food for long duration missions. The large initial mass of hydroponics systems is paid for over time by saving the mass of stored food. However, the yearly logistics mass required to support a bioregenerative system exceeds the mass of food solids it produces, so that supplying stored dehydrated food always requires less mass than bioregenerative food production. A mixed system that grows about half the food and supplies the other half dehydrated has advantages that allow it to breakeven with stored dehydrated food in about 66 years. However, moderate increases in the hydroponics system mass to achieve high reliability, such as adding spares that double the system mass and replacing the initial system every 100 years, increase the mass cost of bioregenerative life support. In this case, the high reliability half food growing, half food supplying system does not breakeven for 389 years. An even higher reliability half and half system, with three times original system mass and replacing the system every 50 years, never breaks even. Growing food for starship life support requires more mass than providing dehydrated food, even for multigeneration voyages of hundreds of years. The benefits of growing some food may justify the added mass cost. Much more efficient recycling food production is wanted but may not be possible. A single multigenerational interstellar voyage to

    A prospective study of bone scintigraphic findings has been carried out in 63 patients, firmly diagnosed as having ankylosing spondylitis. In addition to abnormal uptake of the radiotracer at the sacroiliac joints, a peripheral arthropathy has been a common finding, particularly in the proximal joints, occurring in up to 50% of patients. Increased uptake of radiotracer in the spine has also been found both diffusely and focally. Focal increases have been noted at the apophyseal joints in 40% of patients and in three patients with a sterile intervertebral diskitis, an unusual complication of this disease only diagnosed in two patients after bone scintigraphy.

    Full Text Available Behcet's disease is a multisystem disease characterized by recurrent oral and genital ulcers, relapsing uveitis, mucocutaneous, articular, gastrointestinal, neurologic, and vascular manifestations. Rheumatologic manifestations may also occur in Behcet's disease, and arthritis and arthralgia are the most common musculoskeletal findings followed by enthesopathy, avascular necrosis, myalgia, and myositis. Although the main pathology of Behcet's disease has been known to be the underlying vasculitis, the etiology and exact pathogenesis of the disease are still unclear. Musculoskeletal findings of Behcet's disease, the relationship between Behcet's disease and spondyloarthropathy disease complex, and the status of bone metabolism in patients with Behcet's disease were discussed in this paper.

    Although colonic diverticulitis has no indication for operation, but in some mistaken cases were operated with a diagnosis of acute appendicitis. We evaluated the CT findings of colonic diverticulitis about 19 cases and of asymptomatic colonic diverticula about 15 cases retrospectively. Diagnosis was confirmed of barium enema and operation. CT are complementary methods of examination that can delineated the range of thickening of the colon and the extension of inflammatory changes around the colon. We also believe that CT findings of colonic diverticulitis are useful for differentiating from a diagnosis of appendicitis. (author)

    Neurologic involvement of Lyme disease typically consists of meningitis, cranial neuropathy, and radiculoneuritis, alone or in combination, lasting for months. From 1976 to 1983, we studied 38 patients with Lyme meningitis. Headache and mild neck stiffness, which fluctuated in intensity, and lymphocytic pleocytosis were the common findings. Half of the patients also had facial palsies, which were unilateral in 12 and bilateral in seven. In addition, 12 patients had motor and/or sensory radiculoneuropathies; asymmetric weakness of extremities was the most common finding. Although incomplete presentations of neurologic involvement of Lyme disease may be confused with other entities, the typical constellation of neurologic symptoms represents a unique clinical picture.

    Currently, residual current operated protective devices (RCDs) have a wide range of application in low voltage power grids and play an important role in preventing electric shock hazards and avoiding fire disasters caused by ground fault. But, the stocking current of the animals and human beings has no relationship with the setting value of action current from the protection devices, and the root mean square (RMS) value of residual current detected is considered the current value to determine if the protector acts or not. Theoretical analysis and operation experiences indicate that such criterion is unavailable in identifying the shocking current signals of the animals and human beings from the summation leakage current .Thus, in order to identify the electric shock signal from the summation leakage current automatically and accurately, intelligent information processing techniques are adopted and identification method based on least square-support vector machine (LS-SVM) with grid search and cross validation optimization are proposed. Firstly, through the experiments simulating various scenarios of rabbits electric shocking on the electric shock experiment platform of residual current operated protective devices(RCDs), signal data of 800 sample points before the one cycle and after three cycles of electric shock are used as electric shock sample data obtained by fault recorder to get the leakage current and electric shock current waveform on the electric shock process of the power supply voltage at maximum time, zero time, and any time. Secondly, the above sample data needed to be filtered to reduce the impact of the non-stationary for noise data. Then, the leakage currents of sampling points are combined into a high dimensional feature vector which is input into LS-SVM and the corresponding electric current of sampling point is employed as output of LS-SVM. The relation between input and output is trained by applying grid search and cross validation to determine

    To evaluate by means of retrospective analysis of neck CT scans the CT findings which suggest kikuchi disease. The authors evaluated the CT findings of seven cases of Kikuchi disease histologically confirmed by excisional biopsy. Four males and three females aged between 12 and 43 (mean;28) years were included. The authors retrospectively analyzed distribution, bilaterality, the presence of aggregation, the presence of intranodal low density after contrast enhancement, the number,size, shape and location of areas of intranodal low density, and the presence of extracapsular extension in involved nodes, as seen on pre-and post-contrast CT scans. Attempts were then made to correlate the CT with the pathologic findings. The range of conditions affecting patients included palpable(7/7) and tender(6/7) nodes, fever(5/7), night sweat(2/7), leukopenia(2/7), and weight loss(1/7). The internal jugular and spinal accessory chains were involved in all seven cases, followed by the submandibular(6/7), submental(5/7), supraclavicular(1/7) and axillary(1/7) nodes. The findings observed also included bilateral involvement of the internal jugular chain(6/7), the spinal accessory chain(5/7), and the submandibular(4/6) and supraclavicular nodes(1/1). CT revealed that in all cases, pathologic lymph nodes showed aggregation in one or several nodal groups, namely a mixed homogeneous(mean, 60%)or inhomogeneous(mean, 40%) enhancement pattern;intranodal low densities with the number(1-7), size(1-7mm) and shape(oval, round, or elongated) of varying degree and predominantly (92%) peripheral location, and extracapsular extension. The CT findings which suggest Kikuchi disease in cervical lymphadenopathy were (1) involvement varying from no intranodal low density to prominent intranodal low densities; (2) intranodal low densities, with the number, size and shape of varying degree and predominantly peripheral location, which were correlated with pathologic findings, including variable intranodal

    The mental health of elderly individuals in rural areas is increasingly relevant as populations age and social structures change. While social support satisfaction is a well-established predictor of quality of life, interpersonal sensitivity symptoms may diminish this relation. The current study extends the findings of Scogin et al by investigating the relationship among interpersonal sensitivity, social support satisfaction, and quality of life among rural older adults and exploring the mediating role of social support in the relation between interpersonal sensitivity and quality of life (N = 128). Hierarchical regression revealed that interpersonal sensitivity and social support satisfaction predicted quality of life. In addition, bootstrapping resampling supported the role of social support satisfaction as a mediator between interpersonal sensitivity symptoms and quality of life. These results underscore the importance of nurses and allied health providers in assessing and attending to negative self-perceptions of clients, as well as the perceived quality of their social networks.

    The current study investigated the moderating role of mother and father autonomy support in the link between youth Attention-Deficit Hyperactivity Disorder (ADHD) symptoms and task perseverance. ADHD symptomatology was assessed using a multi-informant composite of mother, father, and teacher ratings, and youth perseverance and parental support of autonomy were examined using a behavioral observation paradigm (i.e., difficult puzzle task). Results indicated that youth who were rated as exhibiting more symptoms of ADHD persevered less on a difficult puzzle task and that this relationship was moderated by parental level of autonomy support. In the context of high parental autonomy support, the negative relation between ADHD and perseverance became nonsignificant. Findings indicate that supporting youth autonomy may have significant implications for their development and that it would be valuable to aid parents in developing the appropriate skills necessary for them to successfully support their child's autonomy.

    The current study extends the findings of Scogin et al. (2007) by exploring the role of social support in changes in quality of life resulting from home-delivered cognitive behavioral therapy (CBT). One hundred thirty-seven participants, characterized primarily as rural, low resource, and frail, were randomly assigned to either CBT or a minimal support control condition. Hierarchical regression revealed that positive change in satisfaction with social support was associated with improvement in quality of life beyond the effects of the CBT treatment. In addition, pretreatment satisfaction with social support, and change in satisfaction with social support moderated the effect of CBT on quality of life. These results suggest that bolstering social support concomitant to CBT may increase quality of life.

    This study was conducted to determine the relationship between burnout and social support received at work among hospice nurses and midwives in Poland to reveal the connection in working conditions differing in terms of exposure to death and dying situation. A total sample of 117 nurses represented nurses working in polish hospice and maternity wards. No significant differences in the burnout scores were found between hospice nurses and midwives with high superiors' support. However, hospice nurses and midwives with low superiors' support differed significantly in almost every dimension of burnout. Further, the results showed that social support significantly predicted burnout only in case of midwives. The current findings emphasize the role of superiors and their ability to provide support. Intervention programmes targeted at preventing or reducing burnout would be especially important for maternity wards, where enhancing support at a workplace could be crucial. Confirming causality in prospective research is necessary.

    Full Text Available Xin You Tai, Amit BatlaUCL Institute of Neurology, Queen Square, London, UKAbstract: Based on original descriptions of brain calcification by Theodor Fahr, brain calcification, and more specifically basal ganglia calcification, is referred to as Fahr's syndrome. Recent identification of genetic mutations has concerted the description of this erstwhile heterogeneous condition which we refer to here as Fahr's disease. Fahr's disease refers to idiopathic calcification of the basal ganglia without a secondary (non-genetic cause. Idiopathic basal ganglia calcification (IBGC is another term, which offers a more accurate description of this condition. Within the last 2 years, genetic mutations for IBGC have been described in SLC20A2, PDGFB, and PDGFRB. These findings broaden our understanding of the pathophysiology and encourage a search for specific treatment options in this rare but disabling condition. Clinically, parkinsonism, dystonia, and other movement disorders are the most common clinical features, but psychiatric features can predominate. Cases with confirmed genetic mutations reveal new clinical features linked with Fahr's disease, such as headaches. Computed tomography or magnetic resonance imaging is usually the trigger for suspecting Fahr's disease and important for identifying the calcification pattern. Symmetric calcification of the globus pallidus, thalamus, and dentate nucleus is the most common pattern in IBGC, but other parts of the brain such as the cerebellum are involved. Treatment of Fahr's disease is currently limited and is largely symptomatic. A better understanding of this condition in light of genetic findings is important to improve the clinical diagnosis and develop specific treatment options.Keywords: Fahr's disease, basal ganglia calcification, parkinsonism, calcium

    Full Text Available Angela Mariani,1 Antonella Vastola2 1Department of Economic and Legal Studies, University Parthenope, Naples, 2School of Agricultural, Forestry, Food and Environmental Sciences, University of Basilicata, Potenza, Italy Abstract: The winegrowing sector worldwide is strongly committed to improving environmental and social sustainability. The aim of this work, based on a literature review, is to highlight current sustainability perspectives and the related main issues. There is a broad consensus that the challenge to achieve a greater spread of sustainable practices is to enhance environmental and social sustainability while maintaining economic viability. From the producers' point of view, the priority is to bridge the still substantial knowledge gaps in terms of perceived environmental benefits, economic benefits, and costs. Thus, an increased research effort focusing on the costs and benefits of different winegrowing practices and technical assistance with implementation might support their diffusion. Moreover, targeted marketing strategies are needed to: enhance consumers' involvement and their attitude toward sustainable wine; improve understanding and use of sustainable labels and claims; and raise awareness of some environmental credentials of wine packaging, mainly with reference to lightweight glass bottles.

    Epilepsy is one of the most common neurological disorders. Global neurological knowledge is essential for differential diagnosis of epileptic syndromes due to the diversity of ictal semiology, causes and syndromes. Neurologists play an important role in planning the medical care for patients with epilepsy, as medication is the most fundamental therapeutic strategy. Some patients with early-onset epilepsy require joint care by pediatric neurologists, those with intractable epilepsy by neurosurgeons, and those with psychological comorbidity by psychiatrists, and neurologists should play a coordinating role. While there is a great need for neurologists to participate in epilepsy care, neurologists in Japan currently do not participate substantially in the epilepsy management system. It is necessary to train more neurologists who can provide epilepsy care and conduct basic and clinical research on epilepsy by providing continuous education on epilepsy for general neurologists as well as pre- and post-graduate medical students. Most of the patients who require long-term treatment experience many medical problems and social handicaps, such as adverse effects of medication, social stigma, educational disadvantages and difficulties in obtaining driver's license. To improve the quality of life of patients with epilepsy, it is desirable to build broad medical-social networks participated by patients, doctors, neurological nurses, psychologists, social workers, school teachers, managers of employment support facilities and care givers.

    The ALMA Pipeline is the automated data reduction tool that runs on ALMA data. Current version of the ALMA pipeline produces science quality data products for standard interferometric observing modes up to calibration process. The ALMA Pipeline is comprised of (1) heuristics in the form of Python scripts that select the best processing parameters, and (2) contexts that are given for book-keeping purpose of data processes. The ALMA Pipeline produces a "weblog" that showcases detailed plots for users to judge how each step of calibration processes are treated. The ALMA Interferometric Pipeline was conditionally accepted in March 2014 by processing Cycle 0 and Cycle 1 data sets. From Cycle 2, ALMA Pipeline is used for ALMA data reduction and quality assurance for the projects whose observing modes are supported by the ALMA Pipeline. Pipeline tasks are available based on CASA version 4.2.2, and the first public pipeline release called CASA 4.2.2-pipe has been available since October 2014. One can reduce ALMA data both by CASA tasks as well as by pipeline tasks by using CASA version 4.2.2-pipe.

  12. Equatorial potassium currents in lenses.

    Wind, B E; Walsh, S; Patterson, J W

    1988-02-01

    Earlier work with the vibrating probe demonstrated the existence of outward potassium currents at the equator and inward sodium currents at the optical poles of the lens. By adding microelectrodes to the system, it is possible to relate steady currents (J) to the potential difference (PD) measured with a microelectrode. By injecting an outward current (I), it is possible to determine resistances and also the PD at which the steady outward potassium current becomes zero (PDJ = 0). At this PD the concentration gradient for potassium efflux and the electrical gradient for potassium influx are balanced so that there is no net flow of potassium across the membranes associated with the production of J. The PDJ = 0 for 18 rat lenses was 86 mV and that for 12 frogs lenses was -95 mV. This agrees with the potassium equilibrium potential and provides strong evidence to support the view that the outward equatorial current, J, is a potassium current. With the injection of outward current, I, the PD becomes more negative, the outward equatorial current, J, decreases, and the inward current at the optical poles increases. This suggests that there are separate electrical loops for K+ and Na+ that are partially linked by the Na, K-pump. Using Ohm's law, it is possible to calculate the input resistance (R = delta PD/I), the resistance related to the production of J (RJ = delta PD/delta J), and the effect of the combined resistances (delta J/I). The driving force for J can be estimated (PDJ = 0-PD). The relationships among currents, voltages and resistance can be used to determine the characteristics of the membranes that are associated with the outward potassium current observed at the equator. The effects of graded deformation of the lens were determined. The effects were reversible. The sites of inward and outward currents were not altered. Following deformation, the equatorial current, J, increased, and the PD became less negative. The PDJ = 0 remains the same so the ratio of K

    Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We studied correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. In all of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas was involved in 9 cases, and other origin 4 cases. The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.

    Background: Diseases exhibiting osteolysis in children are rare hereditary conditions. Several types have been recognised with different clinical manifestations. One type includes subcutaneous nodules, arthropathy and osteolysis and has been termed NAO syndrome. Previous radiological reports have described the affected bones, usually the carpal and tarsal regions, but a detailed analysis of the radiological findings of both the axial as well as the appendicular skeleton has not been reported. Objectives: To describe the radiological findings in a large group of children with an autosomal recessive disease characterized by nodules, familial arthropathy and osteolysis. Materials and methods: The study comprises 14 patients from 9 families and all patients had the triad of nodulosis, arthropathy and osteolysis (NAO). Results: The most common radiological manifestations were osteopenia, undertubulation of long bones, arthritic changes, sclerotic sutures of the calvaria, osteolysis and muscle contractures. Other common findings were squared vertebrae, broad medial clavicles and brachycephaly. Progress of disease was documented in more than half of the patients. Conclusions: Our study is the first report of the detailed radiological findings of NAO syndrome. In NAO syndrome, both the axial and appendicular skeleton are involved (orig.)
