    Cassava (M. esculenta) gives rise to unique underground stem tubers when stem cuttings are planted in an inverted orientation. The nutritional profile of the stem and root tubers were similar except for protein content which was higher in stem than in root tubers. RT-PCR revealed that several key genes (Mec1, RZF, SuSy1 and PIN2) involved in root tuberization were also expressed in these stem tubers. At five weeks post planting, these genes were expressed in roots and underground stems as in the mature tubers. However at 15 weeks post planting, they were expressed in both root and stem tubers but not in adventitious roots or in the non-tuberized stems. Expression of, the root auxin efflux carrier gene PIN2 in the stem tubers indicate a role for auxin in the stem tuberization process.

    In this paper we discuss the main ethical challenges related to the conduct of medicine quality surveys and make suggestions on how to address them. Most evidence-based information regarding medicine quality derives from surveys. However, existing research ethical guidelines do not provide specific guidance for medicine quality surveys. Hence, those conducting surveys are often left wondering how to judge what counts as best practice. A list of the main ethical challenges in the design and conduct of surveys is presented. It is vital that the design and conduct of medicine quality surveys uphold moral and ethical obligations and analyse the ethical implications and consequences of such work. These aspects include the impact on the local availability of and access to medicines; the confidentiality and privacy of the surveyors and the surveyed; questions as to whether outlet staff personnel should be told they are part of a survey; the need of ethical and regulatory approvals; and how the findings should be disseminated. Medicine quality surveys should ideally be conducted in partnership with the relevant national Medicine Regulatory Authorities. An international, but contextually sensitive, model of good ethical practice for such surveys is needed. © 2016 The Authors.

    2015-09-01

    Full Text Available Resistive switching effect in transition metal oxide (TMO based material is often associated with the valence change mechanism (VCM. Typical modeling of valence change resistive switching memory consists of three closely related phenomena, i.e., conductive filament (CF geometry evolution, conduction mechanism and temperature dynamic evolution. It is widely agreed that the electrochemical reduction-oxidation (redox process and oxygen vacancies migration plays an essential role in the CF forming and rupture process. However, the conduction mechanism of resistive switching memory varies considerably depending on the material used in the dielectric layer and selection of electrodes. Among the popular observations are the Poole-Frenkel emission, Schottky emission, space-charge-limited conduction (SCLC, trap-assisted tunneling (TAT and hopping conduction. In this article, we will conduct a survey on several published valence change resistive switching memories with a particular interest in the I-V characteristic and the corresponding conduction mechanism.

    During 1999 and 2000, approximately 10 million people were affected by famine in Ethiopia. Results of nutrition assessments and surveys conducted by humanitarian organizations were used by donors and government agencies to determine needs for food aid and to make other decisions on geographic allocation of limited resources; however, accurate results might have been hampered by methodological errors. To identify common methodological errors in nutrition assessments and surveys and to provide practical recommendations for improvement. Nutrition assessments and surveys (n = 125) conducted by 14 nongovernmental organizations (NGOs) in 54 woredas (districts) in Ethiopia from May 1, 1999, through July 31, 2000. Surveys were ranked as valid and precise according to 5 criteria: use of population proportional to size sampling, sample size, number of clusters, number of children per cluster, and use of weight-for-height index. Number and proportion of surveys that used standard, internationally accepted methods and reported valid and precise results. Fifty-eight of the 125 surveys (46%) were not intended to be standard 30 x 30 cluster surveys. Of the remaining 67 surveys, 6 (9%) met predetermined criteria for validity and precision. All 67 used the anthropometric index of weight-for-height, with 58 (87%) reporting z scores. Fifty-four (81%) used nonrandom sampling without consideration of population size and 6 (9%) had sample sizes of fewer than 500 persons. Major methodological errors were identified among 30 x 30 cluster surveys designed to measure acute malnutrition prevalence in Ethiopia during the famine of 1999-2000. Donor agencies and NGOs should be educated about the need for improved quality of nutrition assessments and their essential role in directing allocation of scarce food resources.

    The Trauma Center Organizational Culture Survey (TRACCS) instrument was developed to assess organizational culture of trauma centers enrolled in the American College of Surgeons Trauma Quality Program (ACS TQIP). The objective is to provide evidence on the psychometric properties of the factors of TRACCS and describe the current organizational culture of TQIP-enrolled trauma centers. A cross-sectional study was conducted by surveying a sampling of employees at 174 TQIP-enrolled trauma centers. Data collection was preceded by multistep survey development. Psychometric properties were assessed by an exploratory factor analysis (construct validity) and the item-total correlations and Cronbach alpha were calculated (internal reliability). Statistical outcomes of the survey responses were measured by descriptive statistics and mixed effect models. The response rate for trauma center participation in the study was 78.7% (n = 137). The factor analysis resulted in 16 items clustered into three factors as described: opportunity, pride, and diversity, trauma center leadership, and employee respect and recognition. TRACCS was found to be highly reliable with a Cronbach alpha of 0.90 in addition to the three factors (0.91, 0.90, and 0.85). Considerable variability of TRACCS overall and factor score among hospitals was measured, with the largest interhospital deviations among trauma center leadership. More than 80% of the variability in the responses occurred within rather than between hospitals. TRACCS was developed as a reliable tool for measuring trauma center organizational culture. Relationships between TQIP outcomes and measured organizational culture are under investigation. Trauma centers could apply TRACCS to better understand current organizational culture and how change tools can impact culture and subsequent patient and process outcomes.

    The Arkansas Cardiovascular Health Examination Survey is a health and nutrition examination survey designed to serve as a demonstration project for collection of data on the prevalence of chronic diseases and their risk factors at the state level. The survey was conducted from mid-2006 through early 2008. We chose a cross-sectional representative sample of adult residents in Arkansas by using a 3-stage, cluster sample design. Trained interviewers conducted interviews and examinations in respondents' homes, collecting data on risk factors and diseases, blood pressure and anthropometric measurements, and blood and urine samples for analysis and storage. Food frequency questionnaires provided dietary and nutrient intake data. We accomplished the project using a collaborative model among several programs and partners within the state. A total of 4,894 eligible households were contacted by telephone. Of these, refusals accounted for 2,748, and 2,146 gave initial consent to participate, for an initial response rate of 44%. The final number of completed household visits was 1,385, resulting in a final response rate of 28.3%. The Arkansas Cardiovascular Health Examination Survey is among the first state-level health and nutrition examination surveys to be conducted in the United States. By using a collaborative model and leveraging federal funds, we engaged several partners who provided additional resources to complete the project. The survey provides the state with valuable state-level data and information for program design and delivery.

    2011-07-01

    In Finland, workplace surveys are used to identify and assess health risks and problems caused by work and make suggestions for continuous improvement of the work environment. With the aid of the workplace survey, occupational health services can be tailored to a company. The aims of this study were to determine how occupational health professionals gather data via the workplace survey and the effect survey results have on companies. A total of 259 occupational health nurses and 108 occupational health physicians responded to the questionnaire: 84.2% were women and 15.8% were men. The mean age of the respondents was 48.8 years (range, 26 to 65 years). Usually occupational health nurses and foremen and sometimes occupational health physicians and occupational safety and health representatives initiate the workplace survey. More than 90% of the surveys were followed by action proposals, and about 50% of these were implemented. The proposals implemented most often concerned personal protective equipment and less often leadership. Survey respondents should have both the opportunity and the authority to affect resources, the work environment, work arrangements, and tools. Teamwork among occupational health and safety professionals, management, and employees is vital for cost-effectively solving today's complex problems at workplaces around the globe.

    Full Text Available Fresh, bias-free and valid data collected using different survey modes is considered an essential requirement for smooth functioning and evolution of an organization. Surveys play a major role in making in-time correct decisions and generating reports. The aim of this study is to compare and investigate state-of-the-art in different survey modes including print, email, online, mobile and SMS-based surveys. Results indicated that existing methods are neither complete nor sufficient to fulfil the overall requirements of an organization which primarily rely on surveys. Also, it shows that SMS is a dominant method for data collection due to its pervasiveness. However, existing SMS-based data collection has limitations like limited number of characters per SMS, single question per SMS and lake of multimedia support. Recent trends in data collection emphasis on data collection applications for smart phones. However, in developing countries low-end mobile devices are still extensively used which makes the data collection difficult from man in the street. The paper conclude that existing survey modes and methods should be improved to get maximum responses quickly in low cost manner. The study has contributed to the area of surveying and data collection by analysing different factors such as cost, time and response rate. The results of this study can help practitioners in creating a more successful surveying method for data collection that can be effectively used for low budget projects in developed as well as developing countries.

    Full Text Available Abstract Background As biobanks play an increasing role in the genomic research that will lead to precision medicine, input from diverse and large populations of patients in a variety of health care settings will be important in order to successfully carry out such studies. One important topic is participants’ views towards consent and data sharing, especially since the 2011 Advanced Notice of Proposed Rulemaking (ANPRM, and subsequently the 2015 Notice of Proposed Rulemaking (NPRM were issued by the Department of Health and Human Services (HHS and Office of Science and Technology Policy (OSTP. These notices required that participants consent to research uses of their de-identified tissue samples and most clinical data, and allowing such consent be obtained in a one-time, open-ended or “broad” fashion. Conducting a survey across multiple sites provides clear advantages to either a single site survey or using a large online database, and is a potentially powerful way of understanding the views of diverse populations on this topic.

    Medication errors in oncology may cause severe clinical problems due to low therapeutic indices and high toxicity of chemotherapeutic agents. We aimed to investigate unintentional medication errors and underlying factors during chemotherapy preparation and administration based on a systematic survey conducted to reflect oncology nurses experience. This study was conducted in 18 adult chemotherapy units with volunteer participation of 206 nurses. A survey developed by primary investigators and medication errors (MAEs) defined preventable errors during prescription of medication, ordering, preparation or administration. The survey consisted of 4 parts: demographic features of nurses; workload of chemotherapy units; errors and their estimated monthly number during chemotherapy preparation and administration; and evaluation of the possible factors responsible from ME. The survey was conducted by face to face interview and data analyses were performed with descriptive statistics. Chi-square or Fisher exact tests were used for a comparative analysis of categorical data. Some 83.4% of the 210 nurses reported one or more than one error during chemotherapy preparation and administration. Prescribing or ordering wrong doses by physicians (65.7%) and noncompliance with administration sequences during chemotherapy administration (50.5%) were the most common errors. The most common estimated average monthly error was not following the administration sequence of the chemotherapeutic agents (4.1 times/month, range 1-20). The most important underlying reasons for medication errors were heavy workload (49.7%) and insufficient number of staff (36.5%). Our findings suggest that the probability of medication error is very high during chemotherapy preparation and administration, the most common involving prescribing and ordering errors. Further studies must address the strategies to minimize medication error in chemotherapy receiving patients, determine sufficient protective measures

    The aim of this paper is to advance rigorous Internet-based HIV/STD Prevention quantitative research by providing guidance to fellow researchers, faculty supervising graduates, human subjects' committees, and review groups about some of the most common and challenging questions about Internet-based HIV prevention quantitative research. The authors represent several research groups who have gained experience conducting some of the first Internet-based HIV/STD prevention quantitative surveys in the US and elsewhere. Sixteen questions specific to Internet-based HIV prevention survey research are identified. To aid rigorous development and review of applications, these questions are organized around six common criteria used in federal review groups in the US: significance, innovation, approach (broken down further by research design, formative development, procedures, sampling considerations, and data collection); investigator, environment and human subjects' issues. Strategies promoting minority participant recruitment, minimizing attrition, validating participants, and compensating participants are discussed. Throughout, the implications on budget and realistic timetabling are identified.

    2015-01-01

    In the US, once a medical device is made available for use, several requirements have been established by the US Food and Drug Administration (FDA) to ensure ongoing post-market surveillance of device safety and effectiveness. Our objective was to determine how commonly medical device manufacturers initiate post-market clinical studies or augment FDA post-market surveillance requirements for higher-risk devices that are most often approved via the FDA's pre-market approval (PMA) pathway. We conducted a cross-sectional survey of 47 manufacturers with operations in California, Minnesota, and Massachusetts who market devices approved via the PMA pathway. Among 22 respondents (response rate =47%), nearly all self-reported conducting post-market clinical research studies, commonly between 1 and 5; only 1 respondent reported never conducting post-market clinical research studies. While manufacturers most often engaged in these studies to satisfy FDA requirements, other reasons were reported, including performance monitoring and surveillance and market acceptance initiatives. Risks of conducting and not conducting post-market clinical research studies were described through open-ended response to questions. Medical device manufacturers commonly initiate post-market clinical studies at the request of the FDA. Clinical data from these studies should be integrated into national post-market surveillance initiatives.

    Migrants living in Germany are a both large and vulnerable population subgroup. They are not easily induced to participate in health surveys, Hence, achieving high participation rates of migrants in health surveys and avoiding selection bias is a difficult task. In this study, we report on the participation of migrants in the German National Health Telephone Survey 2003 (GSTel03), the first comprehensive national health survey conducted by telephone in Germany. Three migrant groups were identified: individuals with non-German citizenship (foreigners), naturalized migrants, and ethnic German immigrants (Spätaussiedler). The aim of this study is to evaluate the degree to which the GSTel03 subsample of foreigners is representative for foreigners living in Germany. We compare the prevalence of sociodemographic characteristics and selected health indicators of foreigners in the GNTel03 subsample with prevalences from national statistics and from a large national household survey ("Mikrozensus 2003"). The proportion of participants with non-German nationality in the overall GSTel03 sample was significantly lower than the proportion of foreigners in the residential population in Germany (3.7 % vs. 8.9 %). While there was no evidence of selection bias with regard to age and sex distribution, we found significant differences with regard to other factors, including nationality, length of stay in Germany, unemployment rate and education. The comparison of health indicators showed only moderate differences between GSTel03 sample and "Mikrozensus" results. However, these differences did not consistently point to a better or worse health status in the GSTel03 sample of foreigners and should therefore not be generalised in respect of other health indicators. Our study emphasises the importance of a continuous effort to improve migrant participation in health studies and of a thorough analysis of selection bias when interpreting results.

    With the recent development of more sensitive biomarkers to assess kidney injury preclinically, a survey was designed i) to investigate what strategies are used to investigate renal toxicity in both ICH S7A compliant Safety Pharmacology (SP) studies after a single dose of a compound and within repeat-dose toxicity studies by large pharmaceutical companies today; ii) to understand whether renal SP studies have impact or utility in drug development and/or if it may be more appropriate to assess renal effects after multiple doses of compounds; iii) to ascertain how much mechanistic work is performed by the top 15 largest pharmaceutical companies (as determined by R&D revenue size); iv) to gain an insight into the impact of the validation of DIKI biomarkers and their introduction in the safety evaluation paradigm; and v) to understand the impact of renal/urinary safety study data on progression of projects. Two short anonymous surveys were submitted to SP leaders of the top 15 pharmaceutical companies, as defined by 2012 R&D portfolio size. Fourteen multiple choice questions were designed to explore the strategies used to investigate renal effects in both ICH S7A compliant SP studies and within toxicology studies. A 67% and 60% response rate was obtained in the first and second surveys, respectively. Nine out of ten respondent companies conduct renal excretory measurements (eg. urine analysis) in toxicology studies whereas only five out of ten conduct specific renal SP studies; and all of those 5 also conduct the renal excretory measurements in toxicology studies. These companies measure and/or calculate a variety of parameters as part of these studies, and also on a case by case basis include regulatory qualified and non-qualified DIKI biomarkers. Finally, only one company has used renal/urinary functional data alone to stop a project, whereas the majority of respondents combine renal data with other target organ assessments to form an integrated decision-making set

    In situ measurements of thermal conductivity and diffusivity of bedrock were investigated with the aid of a literature survey and theoretical simulations of a measurement system. According to the surveyed literature, in situ methods can be divided into `active` drill hole methods, and `passive` indirect methods utilizing other drill hole measurements together with cutting samples and petrophysical relationships. The most common active drill hole method is a cylindrical heat producing probe whose temperature is registered as a function of time. The temperature response can be calculated and interpreted with the aid of analytical solutions of the cylindrical heat conduction equation, particularly the solution for an infinite perfectly conducting cylindrical probe in a homogeneous medium, and the solution for a line source of heat in a medium. Using both forward and inverse modellings, a theoretical measurement system was analysed with an aim at finding the basic parameters for construction of a practical measurement system. The results indicate that thermal conductivity can be relatively well estimated with borehole measurements, whereas thermal diffusivity is much more sensitive to various disturbing factors, such as thermal contact resistance and variations in probe parameters. In addition, the three-dimensional conduction effects were investigated to find out the magnitude of axial `leak` of heat in long-duration experiments. The radius of influence of a drill hole measurement is mainly dependent on the duration of the experiment. Assuming typical conductivity and diffusivity values of crystalline rocks, the measurement yields information within less than a metre from the drill hole, when the experiment lasts about 24 hours. We propose the following factors to be taken as basic parameters in the construction of a practical measurement system: the probe length 1.5-2 m, heating power 5-20 Wm{sup -1}, temperature recording with 5-7 sensors placed along the probe, and

    Full Text Available Joseph S Ross, Katrina L Blount, Jessica D Ritchie, Beth Hodshon, Harlan M Krumholz Center for Outcomes Research and Evaluation, Yale-New Haven Hospital, New Haven, CT, USA Background: In the US, once a medical device is made available for use, several requirements have been established by the US Food and Drug Administration (FDA to ensure ongoing post-market surveillance of device safety and effectiveness. Our objective was to determine how commonly medical device manufacturers initiate post-market clinical studies or augment FDA post-market surveillance requirements for higher-risk devices that are most often approved via the FDA's pre-market approval (PMA pathway. Methods and results: We conducted a cross-sectional survey of 47 manufacturers with operations in California, Minnesota, and Massachusetts who market devices approved via the PMA pathway. Among 22 respondents (response rate =47%, nearly all self-reported conducting post-market clinical research studies, commonly between 1 and 5; only 1 respondent reported never conducting post-market clinical research studies. While manufacturers most often engaged in these studies to satisfy FDA requirements, other reasons were reported, including performance monitoring and surveillance and market acceptance initiatives. Risks of conducting and not conducting post-market clinical research studies were described through open-ended response to questions. Conclusion: Medical device manufacturers commonly initiate post-market clinical studies at the request of the FDA. Clinical data from these studies should be integrated into national post-market surveillance initiatives. Keywords: FDA, PMA pathway, post-market surveillance

    The aim of our study was to identify possible risk factors related to carrying out of illegal conducts by minors on their first offense, and any individual variables, family, economic and socio-cultural related to phenomenon also investigated. The longitudinal study involved the acquisition of a series of biographical information, family, school, behavioral and clinical characteristics of children on their first crime recruited over a year in Puglia Region. For its purpose the study involved the use two standardized clinical scales (Youth Self-Report and Conners Adolescent Self Report Scale). For over a year we proceeded to follow-up. The survey revealed some variables family, social and school related to antisocial behavior of children in their first contact with the judicial authorities. The results confirm the need for primary and secondary prevention of children at risk through mutidisciplinary, early, selective interventions.

    In 2006, a medico-legal consultation service devoted to adult victims of interpersonal violence was set up at the Lausanne University Hospital Centre, Switzerland: the Violence Medical Unit. Patients are received by forensic nurses for support, forensic examination (in order to establish medical report) and community orientation. In 2008, a telephone survey was conducted on patients. The objectives of the survey were to estimate the degree of patients' satisfaction and to document the use of the medical report by six questions. Among the 476 patients admitted to the VMU in 2007, 132 were interviewed. Their overall satisfaction was high with an average mark of 8.7/10. The medical report was used extensively by the interviewed victims (81%) for its primary function - to be produced as evidence. As the consultations are financed by public funds, these results were of interest for advocacy of long-lasting financial support.

    Prior research indicates that conduct disorder (CD) is associated with a range of co-morbid mental disorders. However, the actual prevalence, subtypes and patterns of co-morbidity of DSM-IV-defined CD in the general US population remains unknown. Retrospective assessment of CD and other DSM-IV disorders was conducted using fully structured diagnostic interviews among a nationally representative sample of respondents (n=3199) in the National Comorbidity Survey Replication (NCS-R). The estimated lifetime prevalence of CD in the US is 9.5% (12.0% among males and 7.1% among females), with a median age-of-onset of 11.6 (0.2) years. Latent class analysis (LCA) identified five CD subtypes characterized by rule violations, deceit/theft, aggression, severe covert behaviors, and pervasive CD symptoms. A dose-response relationship was revealed between CD subtype severity and risk of subsequent disorders. Results also indicated that CD typically precedes mood and substance use disorders, but most often occurs after impulse control and anxiety disorders. Although both active and remitted CD is associated with increased risk of the subsequent first onset of other mental disorders, remitted CD is associated with significantly lower risk of subsequent disorders. CD is prevalent and heterogeneous in the US population, and more severe subtypes and the presence of active CD are associated with higher risk of co-morbid disorders. Future prospective studies using general population samples will further inform the nature and course of this disorder.

  17. Learning lessons from field surveys in humanitarian contexts: a case study of field surveys conducted in North Kivu, DRC 2006-2008

    Full Text Available Abstract Survey estimates of mortality and malnutrition are commonly used to guide humanitarian decision-making. Currently, different methods of conducting field surveys are the subject of debate among epidemiologists. Beyond the technical arguments, decision makers may find it difficult to conceptualize what the estimates actually mean. For instance, what makes this particular situation an emergency? And how should the operational response be adapted accordingly. This brings into question not only the quality of the survey methodology, but also the difficulties epidemiologists face in interpreting results and selecting the most important information to guide operations. As a case study, we reviewed mortality and nutritional surveys conducted in North Kivu, Democratic Republic of Congo (DRC published from January 2006 to January 2009. We performed a PubMed/Medline search for published articles and scanned publicly available humanitarian databases and clearinghouses for grey literature. To evaluate the surveys, we developed minimum reporting criteria based on available guidelines and selected peer-review articles. We identified 38 reports through our search strategy; three surveys met our inclusion criteria. The surveys varied in methodological quality. Reporting against minimum criteria was generally good, but presentation of ethical procedures, raw data and survey limitations were missed in all surveys. All surveys also failed to consider contextual factors important for data interpretation. From this review, we conclude that mechanisms to ensure sound survey design and conduct must be implemented by operational organisations to improve data quality and reporting. Training in data interpretation would also be useful. Novel survey methods should be trialled and prospective data gathering (surveillance employed wherever feasible.

    To examine the perceptions of the code of professional conduct among practising registered nurses in Hong Kong. A code of professional conduct is intended to guide nurses in their practice and to ensure congruence with nursing goals and objectives. Such a code for nurses in Hong Kong has been in effect for two decades but, to date, no study has examined the perceptions of it among practising nurses. A survey of 320 practising registered nurses working in a hospital cluster in Hong Kong (mean postregistration experience=11.8 years). A questionnaire developed to assess nurses' perceptions of the Code of Professional Conduct devised by the Nursing Council of Hong Kong. Providing safe and competent care, practising in accordance with the law and maintaining agreed standards were ranked in order as the three most important aspects. Safeguarding informed decision-making for patients who were mentally incapacitated or unable to speak for themselves, participating in continuing nursing education and raising objections to practices that compromise safe and appropriate care were considered the most challenging aspects to achieve in professional nursing practice. To educate nurses to become more assertive in safeguarding patients' rights and to encourage and support lifelong learning remains a major challenge in professional nursing practice. The profession and statutory bodies need to consider how best to enable practising nurses to address these issues. Examining the perceptions of practising nurses about the professional code is necessary to ensure that the profession is prepared to meet the ever-changing demands and expectations of the public whom it claims to serve. © 2010 Blackwell Publishing Ltd.

    During the 1991 Gulf War, the Iraqi army set Kuwait oil wells on fire. Wells and some oil refineries were burned, resulting in Kuwait and the surrounding Gulf region being exposed to toxic gases. The oil fires reached their peak in February 1991. On March 7, the fires in some fields were still burning at peak strength. Sulfur dioxide, particulates, carbon monoxide, and nitrogen oxides were emitted into the atmosphere. All of these substances can cause adverse health effects, which vary according to concentration and duration of exposure. A survey conducted in Kuwait clinics and emergency rooms showed an increase in upper respiratory irritation consistent with environmental air sampling results, indicating occasional high levels of particulates. Patient visits related to gastrointestinal illness, heart disease, psychiatric illness, chronic bronchitis and emphysema, and bronchiectasis increased during the period following the burning of the oil wells. There was no documented evidence of an increase in visits for acute upper and lower respiratory infections or asthma. Public health workers must recognize the high priority of collecting long-term health data and developing public health systems to assess those data. Copyright 1997 Academic Press.

    To examine whether HPV vaccination influences sexual behaviour in adolescent girls, either by giving them a 'green light' to have sex, or because perceived protection afforded by the vaccine permits compensatory risky sexual behaviour. Cross-sectional and longitudinal surveys. Seven English schools. Self-reported sexual behaviour. The cross-sectional survey included 1053 girls (mean age 17.1 years) who had (n=433 recruited in March 2010) or had not (n=620 recruited in March 2009) been offered the HPV vaccine. The longitudinal survey included 407 girls (mean age 17.5 years) who had been offered HPV vaccination and had either received at least one dose (n=148) or had not received any doses (n=259). In the cross-sectional survey, the group of girls who had been offered the HPV vaccine were no more likely to be sexually active than the group of girls who had not been offered the HPV vaccine. In the longitudinal survey, the vaccinated group were no more likely to have changed their condom use or increased their total number of sexual partners than the unvaccinated group. Neither being offered the HPV vaccine nor receiving it affected sexual behaviour. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available At the time of our investigation, the CU was not a widespread concept in Argentina, being viewed as a “foreign - far long project” (coming from developed countries and standing for the long term. It is suggested that the rate of CU evolution, in emerging countries like Argentina, is more related to mentality issues than to CU strategic or operative limitations. Although the executives who replied to a survey were not the only power factor in their organization, their comments allow us to think that, in those countries, the CU may have a better future perspective. The research used a quali-quantitative methodology, which was based on a survey to top executives of different kinds of companies located in Argentina. The research design was not experimental and transversal, as it was limited to a specific moment in time.

    The feasibility of performing, numerous spent fuel cask operations using fully integrated robotic systems is under evaluation. Using existing technology, operational and descriptive software and hardware in the form of robotic end effectors are being designed in conjunction with interfacing cask components. A robotic radiation and contamination survey system has been developed and used on mock-up cask hardware to evaluate the impact of such fully automated operations on cask design features and productivity. Based on experience gained from the survey system, numerous health physics operations can be reliably performed with little human intervention using a fully automated system. Such operations can also significantly reduce time requirements for cask-receiving operations. 7 refs., 51 figs., 6 tabs.

     Under the Japanese drug regulatory system, post-marketing studies (PMS) must be in compliance with Good Post-marketing Study Practice (GPSP). The GPSP Ordinance lacks standards for the ethical conduct of PMSs; although only post-marketing clinical trials are subject to Good Clinical Practice. We conducted a web-based questionnaire survey on the ethical conduct of PMSs in collaboration with the Japanese Society of Hospital Pharmacists and pharmacists belonging to the Society. 1819 hospitals around Japan answered the questionnaire, of which 503 hospitals had conducted company-sponsored PMSs in 2015. 40.2% of the hospitals had obtained informed consent from participating patients in at least one PMS conducted in 2015, the majority of which was in written form. The first and second most frequent reasons for seeking informed consent in PMSs were to meet protocol requirements, followed by the requirement to meet institutional standard operational procedures and the request of the ethical review board of the hospital. Ethical review of PMSs was conducted in 251 hospitals. Despite a lack of standards for informed consent and ethical review in PMSs, a considerable number of study sites employed informed consent and ethical review for PMSs. While company policies and protocols are likely to be major determinants of the ethical conduct of PMSs, the governmental regulatory agency should also play a significant role in implementing a standardized ethical code for the conduct of PMSs.

    BACKGROUND Since the early 1990s, programs to control Chagas disease in South America have focused on eradicating domiciliary Triatoma infestans, the main vector. Seroprevalence studies of the chagasic infection are included as part of the vector control programs; they are essential to assess the impact of vector control measures and to monitor the prevention of vector transmission. OBJECTIVE To assess the interruption of domiciliary vector transmission of Chagas disease by T. infestans in Paraguay by evaluating the current state of transmission in rural areas. METHODS A survey of seroprevalence of Chagas disease was carried out in a representative sample group of Paraguayans aged one to five years living in rural areas of Paraguay in 2008. Blood samples collected on filter paper from 12,776 children were tested using an enzyme-linked immunosorbent assay. Children whose serology was positive or undetermined (n = 41) were recalled to donate a whole blood sample for retesting. Their homes were inspected for current triatomine infestation. Blood samples from their respective mothers were also collected and tested to check possible transmission of the disease by a congenital route. FINDINGS A seroprevalence rate of 0.24% for Trypanosoma cruzi infection was detected in children under five years of age among the country’s rural population. Our findings indicate that T. cruzi was transmitted to these children vertically. The total number of infected children, aged one to five years living in these departments, was estimated at 1,691 cases with an annual incidence of congenital transmission of 338 cases per year. MAIN CONCLUSION We determined the impact of vector control in the transmission of T. cruzi, following uninterrupted vector control measures employed since 1999 in contiguous T. infestans-endemic areas of Paraguay, and this allowed us to estimate the degree of risk of congenital transmission in the country.

  14. Employment of broadband seismometers to conduct micro-gravity monitoring surveys on active volcanoes

    Micro-gravity monitoring through discrete measurements can be used at active volcanoes to identify and model processes within the volcanic system. Mass redistributions occurring over a wide range of depths can be detected. However, the lack of information on the rate at which volcanic processes occur (due to time lapse between successive surveys) limits considerably this method. Continuous gravity changes in volcanic environments can constrain fluid and gas transport at depth. This method does, nevertheless, have some drawbacks. The high cost of gravity meters prevents observatories deploying arrays of these instruments. Thus the temporal advantage of continuous gravity measurements is outweighed by the spatial disadvantage of this type of monitoring compared with traditional micro-gravity. Apart from conventional gravimeters, good quality gravity data can also be retrieved from digital records of the output of broadband seismometers. In this work, we analyse several constituents of the geophysical noise affecting the signal. Factors such as the oceanic loading and subsequent tilt can have an important effect on the record, especially for coastal stations. These disturbances are registered by the two horizontal components of tri-axial broadband seismometers, which can be used to identify the contribution of different observable noise sources, allowing application of various corrections to the data and removal from the signal obtained from vertical sensors. Finally, the possibility of continuously measuring micro-gravity changes using broadband seismometers in the field is discussed, with a special emphasis on the complex multi-parameter settings that we find in active volcanoes. The relatively low cost and portability of these devices may make them suitable for the deployment of networks investigating gravitational effect produced by volcanic and magmatic processes.

    Antibiotics prescribing by physicians have gained due importance across the globe, mainly because of an increase in antibiotic usage, prevalence of infections and drug resistances. The present study is aimed to evaluate the physicians prescribing pattern of antibiotics, their usages by outpatients and disease conditions for which the antibiotics are prescribed in three cities of Bangladesh. This cross sectional health survey was carried out with a self designed standard questionnaire by manual data collection over a three months period (20.03.2013 to 20.06.2013) at three adjacent cities Jessore Sadar, Monirampur and Keshabpur upazila respectively. The data were collected from the patient's prescription and by directly interviewing the patients who were prescribed at least one antibiotic during the study period. WHO Anatomical Therapeutic Chemical (ATC) classifications for antibiotics was used and descriptive statistics were applied to the collected data and analyzed using Microsoft Excel software. Modified Wald method was applied to calculate 95% CI. A total of 900 prescriptions were analyzed during the study period. It was found that the prescriber prescribed antibiotics to the patients who were suffering mainly from cold and fever, infections, diarrhea and gonorrhea. The highest prescribed antibiotic groups were cephalosporins (31.78%), macrolides (27.33%), quinolones (16.33%), penicillins (7.11%), and metronidazoles (6.78%) respectively. Two or more antibiotics were prescribed in 25.44% of prescriptions. A total of 66.89% prescriptions had complete information on dosage form, 57% had complete direction for antibiotics use and 64.22% patients completed full course of antibiotics. Although 83% prescriptions have no clinical test for using antibiotics, even though the percentages of patients' disease recovery were 61.78% and in compliance were 38.22%. From this research, it is observed that physicians prescribed antibiotics rationally in some cases but needs to

    The New Energy and Industrial Technology Development Organization (NEDO) conducted studies covering Wyoming, Utah, Colorado, New Mexico, and North Dakota, all in the West. Illinois and Gulf-Texas are also included. The bituminous coal of Utah and Colorado is given the highest priority as coal to be exported to Japan. It is feared, however, that the price of the bituminous coal from these areas may soar if demand increases. As for sub-bituminous coal, its price is far more stable because its reserves are basically limitless. The sub-bituminous coal, however, is not expected to be imported to Japan in the very near future because it is low in calorific power and fails to meet the conditions prerequisite to Japan's boiler fuel. Illinois can receive large orders but its coal contains more sulfur than the Western coal and a longer distance has to be covered for its transportation. As for transportation to the West Cost, freight cars are available and the port capacity can be enlarged dependent on the magnitude of demand for coal. Loading a deep draft bulk ship off shore with coarse coal slurry by pipeline is an attractive scheme. (NEDO)

    Full Text Available Abstract Background A substantial proportion of the psychiatric burden of disease falls on the world's poorest nations, yet relatively little is known about randomised trials conducted in these countries. Our aim was to identify and describe a representative sample of mental health trials from low and middle-income countries. Methods 6107 electronic records, most with full text copies, were available following extensive searches for randomised or potentially randomised trials from low and middle-income countries published in 1991, 1995 and 2000. These records were searched to identify studies relevant to mental health. Data on study characteristics were extracted from the full text copies.

    Full Text Available The article deals with methodological challenges in conducting large-N surveys on policy work in central public administration. Based upon current work on the topic as well as the author’s experience with a large-N survey in the Czech Republic’s ministries, these challenges include: 1 definition of theoretical sample, 2 obtaining sample frame and support from the ministry, and 3 methods of sampling and data gathering. It is shown that traditional conceptions of a “policy analyst“ are not adequate for research design because a this term does not include everyone who might be doing policy work, and b in some countries there is simply no such job position. It is argued that: 1 there should be a closer connection between the theory of policy work and empirical surveys, especially in terms of clearer definition of theoretical population; 2 it would be useful to expand the operationalization of policy work in public administration to include all civil servants except those who work exclusively in the internal operations of the ministry; 3 researchers should be more transparent in describing their methodology (how the sample frame was constructed, how the units from the sample frame were chosen etc.; 4 researchers should better reflect potential weakness of research design (especially sampling bias; 5 more effort to estimate data quality should be made; 6 these surveys should be accompanied by qualitative in-depth studies. The appendix of the article provides detailed information about the methodology of the Czech Republic survey.

    Background A substantial proportion of the psychiatric burden of disease falls on the world's poorest nations, yet relatively little is known about randomised trials conducted in these countries. Our aim was to identify and describe a representative sample of mental health trials from low and middle-income countries. Methods 6107 electronic records, most with full text copies, were available following extensive searches for randomised or potentially randomised trials from low and middle-income countries published in 1991, 1995 and 2000. These records were searched to identify studies relevant to mental health. Data on study characteristics were extracted from the full text copies. Results Trials relevant to mental health were reported in only 3% of the records. 176 records reporting 177 trials were identified: 25 were published in 1991, 45 in 1995, and 106 in 2000. Participants from China were represented in 46% of trials described. 68% of trials had <100 participants. The method of sequence generation was described in less than 20% of reports and adequate concealment of allocation was described in only 12% of reports. Participants were most frequently adults with unipolar depression (36/177) or schizophrenia (36/177). 80% of studies evaluated pharmacological interventions, a third of which were not listed by WHO as essential drugs. 41% of reports were indexed on PubMed; this proportion decreased from 68% in 1991 to 32% in 2000. Conclusion In terms of overall health burden, trial research activity from low and middle-income countries in mental health appears to be low, and in no area adequately reflects need. PMID:18702809

    This report presents results of a 2008/2009 survey of hydrogen and fuel cell awareness conducted for the U.S. Department of Energy (DOE). The 2008/2009 survey follows up on a similar DOE survey conducted in 2004, measuring levels of awareness and understanding of hydrogen and fuel cell technologies in four populations: (1) the general public, (2) students, (3) personnel in state and local governments, and (4) potential end users of hydrogen and fuel cell technologies in business and industry. The 2008/2009 survey includes these four groups and adds a fifth group, safety and code officials. The same survey methods were used for both surveys; the 2008/2009 survey report includes a comparison of 2004 and 2008/2009 findings. Information from these surveys will be used to enhance hydrogen and fuel cell education strategies.

    Full Text Available Between the elements which mark the global processes, we can include educational issues, the management of processes in pre-university education. Therefore, the synthetic approach to educational problems in Romania, studied in terms of the processes and the phenomena of social development, but also due to the need for submiting the pre-university Romanian educational process to the European Union requirements, appears to be current and important. This analysis focuses on the decentralization of education. This theme is a true significant of the stage and of the the changing potential of the management practice in the public area. Its actuality is also hard to contest under the conditions in which changes in this area have been slow compared to those of the other countries that joined the European Union (Hungary, Czech Republic, Poland, contradictory and inconsistent (Herczynski and Levitas, 2001: 1-2. The legislative changes, training facilities, as well as the constant institutional reorganization of pre-university education show the presence of an active interest in this matter. However, the real reform of university education still requires essential improvements. This study analyzes the social perception of performers in pre-university system, establishes positive and negative aspects of the reform in pre-university education, all from the perspective of teachers. The research was conducted between March 1st, 2011 and April 1st, 2011. During this time the questionnaire was applied and the data interpreted. The data obtained from the questionnaire interpretation were introduced into the SPSS program. For the analysis and interpretation of data we used SPSS 15.0. under Windows license. My investigation efforts were directed towards the impact of decentralization on the performers in pre-university education system and on their perception. The main purpose of the experimental study was to determine the essential perceptions of the performers

    Purpose - Ukraine is home to Europe's worst HIV epidemic, overwhelmingly fueled by people who inject drugs who face harsh prison sentences. In Ukraine, HIV and other infectious diseases are concentrated in prisons, yet the magnitude of this problem had not been quantified. The purpose of this paper is to evaluate the systematic health survey of prisoners in the former Soviet Union (FSU). Design/methodology/approach - Qualitative interviews were carried out with research and prison administrative staff to assess the barriers and facilitators to conducting a bio-behavioral survey in Ukrainian prisons. Findings - Crucial barriers at the institutional, staff, and participant level require addressing by: first, ensuring Prison Department involvement at every stage; second, tackling pre-conceived attitudes about drug addiction and treatment among staff; and third, guaranteeing confidentiality for participants. Originality/value - The burden of many diseases is higher than expected and much higher than in the community. Notwithstanding the challenges, scientifically rigorous bio-behavioral surveys are attainable in criminal justice systems in the FSU with collaboration and careful consideration of this specific context.

    The UK Clinical Research Collaboration (UKCRC) registered Clinical Trials Units (CTUs) Network aims to support high-quality, efficient and sustainable clinical trials research in the UK. To better understand the challenges in efficient trial conduct, and to help prioritise tackling these challenges, we surveyed CTU staff. The aim was to identify important inefficiencies during two key stages of the trial conduct life cycle: (i) from grant award to first participant, (ii) from first participant to reporting of final results. Respondents were asked to list their top three inefficiencies from grant award to recruitment of the first participant, and from recruitment of the first participant to publication of results. Free text space allowed respondents to explain why they thought these were important. The survey was constructed using SurveyMonkey and circulated to the 45 registered CTUs in May 2013. Respondents were asked to name their unit and job title, but were otherwise anonymous. Free-text responses were coded into broad categories. There were 43 respondents from 25 CTUs. The top inefficiency between grant award and recruitment of first participant was reported as obtaining research and development (R&D) approvals by 23 respondents (53%), contracts by 22 (51%), and other approvals by 13 (30%). The top inefficiency from recruitment of first participant to publication of results was failure to meet recruitment targets, reported by 19 (44%) respondents. A common comment was that this reflected overoptimistic or inaccurate estimates of recruitment at site. Data management, including case report form design and delays in resolving data queries with sites, was reported as an important inefficiency by 11 (26%) respondents, and preparation and submission for publication by 9 (21%). Recommendations for improving the efficiency of trial conduct within the CTUs network include: further reducing unnecessary bureaucracy in approvals and contracting; improving training for site

    Nursing-sensitive quality indicators comprise principles, procedures, and assessments to quantify the level of nursing quality in hospital departments. Although studies have demonstrated that quality indicators are essential for monitoring nursing practice in the operating room (OR), nursing quality in China is highly subjective and localised OR nursing-sensitive quality indicators are lacking. This study aimed to establish scientific, objective and comprehensive nursing-sensitive quality indicators for the OR to evaluate and monitor OR nursing care quality in China. Literature search for relevant evidence-based studies was performed using Cochrane, Medline, PubMed, Embase, and other databases, followed by literature review and group discussion by the expert panel. Two successive rounds of Delphi surveys were conducted using questionnaires completed by the expert panel to reach consensus and define nursing-sensitive quality indicators for the OR. Two rounds of Delphi surveys each had 100% questionnaire retrieval rate, with Kendall W coordination coefficients ranging from 0.096 to 0.263 (PDelphi method. The quality indicators developed in this study may provide an objective and quantitative reference for evaluating nursing quality in Chinese ORs.

    Children with conduct disorders (CD) and their families are in contact with multiple agencies, but there is limited evidence on their patterns of service utilization. The aim of this study was to establish the patterns, barriers and correlates of service use by analysing the cohort of the 2004 Great Britain child mental health survey (N = 7,977). Use of social services was significantly higher by children with CD than emotional disorders (ED) in the absence of co-morbidity, while use of specialist child mental health and paediatric was significantly higher by children with hyperkinetic disorders (HD) than CD. Children who had comorbid physical disorders used more primary healthcare services compared to those without physical disorders. Utilization of specialist child mental heath and social services was significantly higher among children with unsocialized CD than socialized CD and oppositional defiant disorders. Services utilization and its correlates varied with the type of service. Overall, specialist services use was associated with co-morbidity with learning disabilities, physical and psychiatric disorders. Several correlates of services use in CD appeared non-specific, i.e. associated with use of different services indicating the possibility of indiscriminate use of different types of services. The findings led to the conclusion that there is the need for effective organization and co-ordination of services, and clear care pathways. Involvement of specialist child mental health services should be requested in the presence of mental health co-morbidity.

  11. Using detection dogs to conduct simultaneous surveys of northern spotted (Strix occidentalis caurina and barred owls (Strix varia.

    Directory of Open Access Journals (Sweden)

    Samuel K Wasser

    Full Text Available State and federal actions to conserve northern spotted owl (Strix occidentalis caurina habitat are largely initiated by establishing habitat occupancy. Northern spotted owl occupancy is typically assessed by eliciting their response to simulated conspecific vocalizations. However, proximity of barred owls (Strix varia-a significant threat to northern spotted owls-can suppress northern spotted owl responsiveness to vocalization surveys and hence their probability of detection. We developed a survey method to simultaneously detect both species that does not require vocalization. Detection dogs (Canis familiaris located owl pellets accumulated under roost sites, within search areas selected using habitat association maps. We compared success of detection dog surveys to vocalization surveys slightly modified from the U.S. Fish and Wildlife Service's Draft 2010 Survey Protocol. Seventeen 2 km × 2 km polygons were each surveyed multiple times in an area where northern spotted owls were known to nest prior to 1997 and barred owl density was thought to be low. Mitochondrial DNA was used to confirm species from pellets detected by dogs. Spotted owl and barred owl detection probabilities were significantly higher for dog than vocalization surveys. For spotted owls, this difference increased with number of site visits. Cumulative detection probabilities of northern spotted owls were 29% after session 1, 62% after session 2, and 87% after session 3 for dog surveys, compared to 25% after session 1, increasing to 59% by session 6 for vocalization surveys. Mean detection probability for barred owls was 20.1% for dog surveys and 7.3% for vocal surveys. Results suggest that detection dog surveys can complement vocalization surveys by providing a reliable method for establishing occupancy of both northern spotted and barred owl without requiring owl vocalization. This helps meet objectives of Recovery Actions 24 and 25 of the Revised Recovery Plan for the

    Full Text Available Abstract Background Malnutrition prevalence and mortality rates are increasingly used as essential indicators to assess the severity of a crisis, to follow trends, and to guide decision-making, including allocation of funds. Although consensus has slowly developed on the methodology to accurately measure these indicators, errors in the application of the survey methodology and analysis have persisted. The aim of this study was to identify common methodological weaknesses in nutrition and mortality surveys and to provide practical recommendations for improvement. Methods Nutrition (N = 368 and crude mortality rate (CMR; N = 158 surveys conducted by 33 non-governmental organisations and United Nations agencies in 17 countries from October 1993 to April 2004 were analysed for sampling validity, precision, quality of measurement and calculation according to several criteria. Results One hundred and thirty (35.3% nutrition surveys and 5 (3.2% CMR surveys met the criteria for quality. Quality of surveys varied significantly depending on the agency. The proportion of nutrition surveys that met criteria for quality rose significantly from 1993 to 2004; there was no improvement for mortality surveys during this period. Conclusion Significant errors and imprecision in the methodology and reporting of nutrition and mortality surveys were identified. While there was an improvement in the quality of nutrition surveys over the years, the quality of mortality surveys remained poor. Recent initiatives aimed at standardising nutrition and mortality survey quality should be strengthened. There are still a number of methodological issues in nutrition and mortality surveys in humanitarian emergencies that need further study.

    Full Text Available Two small unmanned aerial vehicles, Ant-Plane 6 and Ant-Plane 3, were assembled using parts and technologies developed for model airplanes. The aerial vehicles were scheduled to conduct aero magnetic and photographic surveys of the Brans?eld Basin, from a takeoff runway at Marsh Air?eld on the South Shetland Islands, Antarctica, during January 2011. However, the scheduled surveys were not conducted on account of poor weather. Research was later conducted on a glacier, using a takeoff runway at St. Kliment Ohridski Base, Livingston Island, during December 2011. A ?ight from St. Kliment Ohridski Base to Deception Island yielded satisfactory results; the total distance of 302.4 km was traversed in 3 h 7 min (3:07. On this ?ight, aeromagnetic and aerial photographic data were obtained from an altitude of 780 m for a 9×18 km area on the northern half of Deception Island. Aerial photographs of Deception Island and South Bay showed the distributions of glaciers and their crevasses. The Ant-Plane ?ew over the Antarctic horizon and surveyed above Deception Island. That was the successful venture of this kind, demonstrating that airborne surveys by Ant-Planes are useful for Antarctic research investigations. Airborne surveys provide a safe and economical approach to data acquisition as compared with manned aerial operations.

    To estimate the adult prevalence of HIV among the adult population in Zambia and determine whether demographic characteristics were associated with being HIV positive. A cross sectional population based survey to asses HIV status among participants aged 15 years and above in a national tuberculosis prevalence survey. Counselling was offered to participants who tested for HIV. The prevalence was estimated using a logistic regression model. Univariate and multivariate associations of social demographic characteristics with HIV were determined. Of the 46,099 individuals who were eligible to participate in the survey, 44,761 (97.1 %) underwent pre-test counselling for HIV; out of which 30,605 (68.4 %) consented to be tested and 30, 584 (99.9 %) were tested. HIV prevalence was estimated to be 6.6 % (95 % CI 5.8-7.4); with females having a higher prevalence than males 7.7 % (95 % CI 6.8-8.7) versus 5.2 % (95 % CI 4.4-5.9). HIV prevalence was higher among urban (9.8 %; 95 % CI 8.8-10.7) than rural residents (5.0 %; 95 % CI 4.3-5.8). The risk of HIV was double among urban dwellers than among their rural counterparts. Being divorced or widowed was associated with a threefold higher risk of being HIV positive than being never married. The risk of being HIV positive was four times higher among those with tuberculosis than those without tuberculosis. HIV prevalence was lower than previously estimated in the country. The burden of HIV showed sociodemographic disparities signifying a need to target key populations or epidemic drivers. Mobile testing for HIV on a national scale in the context of TB prevalence surveys could be explored further in other settings.

    The purpose of this study was to compare current awareness of the "On a Code of Conduct for Scientists" (OCCS) among members of the Japanese Society for Hygiene (JSH). An anonymous self-administered questionnaire was mailed to JSH members, including 439 councilors and 376 junior members (who were under 50 years of age with a membership of 3 years or longer, excluding councilors). Councilors were surveyed from November to December 2007, while junior members were surveyed from November to December 2008. The overall response rate was 40.6% (n = 331/815), with responses from 46.7% of the councilors (n = 205/439) and 33.5% of the junior members (n = 126/376). Among the respondents, 36.0% of councilors (n = 68) and 59.8% of junior members (n = 73) did not know the contents of "On the Code of Conduct for Scientists" (P Code [70.0% of councilors (n = 133), 68.6% of junior members (n = 83)] (P code of conduct for scientists (P Code of Conduct for Scientists. This result provides important information that should be considered during the formulation of an individual code of conduct for scientists in the JSH.

    2010-06-01

    Full Text Available Abstract Background Accurate assessment of the burden of drug-resistant TB requires systematic efforts to quantify its magnitude and trend. In approximately half the countries where resistance has been reported, estimates are based on surveys conducted in public sector facilities. However, in locations where a substantial fraction of TB cases seek care with private providers, these surveys may not accurately measure resistance in the entire population. Methods We describe a mathematical model to investigate biases associated with sampling only from public sector cases in India, where TB treatment is offered in both public and private sectors. We then propose and demonstrate a weighted estimator as an efficient method for including small numbers of cases from the private sector as a way to recover valid estimates of resistance in the population under study. Results We find that public sector surveys rarely provide valid estimates of drug-resistance among new and retreatment cases. Further, the magnitude and direction of the bias are sensitive to many parameters describing the health-seeking behaviours and treatment outcomes of tuberculosis patients, disallowing simple adjustments to recover accurate estimates. Conclusions In locations where large numbers of tuberculosis patients are diagnosed and treated by private sector practitioners who are not typically included in drug resistance surveys, targeted surveys for assessing drug resistance are required to validly estimate resistance.

    Full Text Available A survey of a population-based sample of U.S adults was conducted to measure their attitudes about, and inform the design of the Precision Medicine Initiative's planned national cohort study.An online survey was conducted by GfK between May and June of 2015. The influence of different consent models on willingness to share data was examined by randomizing participants to one of eight consent scenarios.Of 4,777 people invited to take the survey, 2,706 responded and 2,601 (54% response rate provided valid responses. Most respondents (79% supported the proposed study, and 54% said they would definitely or probably participate if asked. Support for and willingness to participate in the study varied little among demographic groups; younger respondents, LGBT respondents, and those with more years of education were significantly more likely to take part if asked. The most important study incentive that the survey asked about was learning about one's own health information. Willingness to share data and samples under broad, study-by-study, menu and dynamic consent models was similar when a statement about transparency was included in the consent scenarios. Respondents were generally interested in taking part in several governance functions of the cohort study.A large majority of the U.S. adults who responded to the survey supported a large national cohort study. Levels of support for the study and willingness to participate were both consistent across most demographic groups. The opportunity to learn health information about one's self from the study appears to be a strong motivation to participate.

    Full Text Available Abstract Background Previous research has found that a “web-push” approach to data collection, which involves contacting people by mail to request an Internet survey response while withholding a paper response option until later in the contact process, consistently achieves lower response rates than a “paper-only” approach, whereby all respondents are contacted and requested to respond by mail. Method An experiment was designed, as part of the Millennium Cohort Family Study, to compare response rates, sample representativeness, and cost between a web-push and a paper-only approach; each approach comprised 3 stages of mail contacts. The invited sample (n = 4,935 consisted of spouses married to U.S. Service members, who had been serving in the military between 2 and 5 years as of October, 2011. Results The web-push methodology produced a significantly higher response rate, 32.8% compared to 27.8%. Each of the 3 stages of postal contact significantly contributed to response for both treatments with 87.1% of the web-push responses received over the Internet. The per-respondent cost of the paper-only treatment was almost 40% higher than the web-push treatment group. Analyses revealed no meaningfully significant differences between treatment groups in representation. Conclusion These results provide evidence that a web-push methodology is more effective and less expensive than a paper-only approach among young military spouses, perhaps due to their heavy reliance on the internet, and we suggest that this approach may be more effective with the general population as they become more uniformly internet savvy.

    The U.S. Geological Survey Earthquake Science Center collects and processes Global Positioning System (GPS) data throughout the western United States to measure crustal deformation related to earthquakes and tectonic processes as part of a long‐term program of research and monitoring. Here, we outline data collection procedures and present the GPS dataset built through repeated temporary deployments since 1992. This dataset consists of observations at ∼1950 locations. In addition, this article details our data processing and analysis procedures, which consist of the following. We process the raw data collected through temporary deployments, in addition to data from continuously operating western U.S. GPS stations operated by multiple agencies, using the GIPSY software package to obtain position time series. Subsequently, we align the positions to a common reference frame, determine the optimal parameters for a temporally correlated noise model, and apply this noise model when carrying out time‐series analysis to derive deformation measures, including constant interseismic velocities, coseismic offsets, and transient postseismic motion.

    Reproducibility in animal research is alarmingly low, and a lack of scientific rigor has been proposed as a major cause. Systematic reviews found low reporting rates of measures against risks of bias (e.g., randomization, blinding), and a correlation between low reporting rates and overstated treatment effects. Reporting rates of measures against bias are thus used as a proxy measure for scientific rigor, and reporting guidelines (e.g., ARRIVE) have become a major weapon in the fight against risks of bias in animal research. Surprisingly, animal scientists have never been asked about their use of measures against risks of bias and how they report these in publications. Whether poor reporting reflects poor use of such measures, and whether reporting guidelines may effectively reduce risks of bias has therefore remained elusive. To address these questions, we asked in vivo researchers about their use and reporting of measures against risks of bias and examined how self-reports relate to reporting rates obtained through systematic reviews. An online survey was sent out to all registered in vivo researchers in Switzerland (N = 1891) and was complemented by personal interviews with five representative in vivo researchers to facilitate interpretation of the survey results. Return rate was 28% (N = 530), of which 302 participants (16%) returned fully completed questionnaires that were used for further analysis. According to the researchers' self-report, they use measures against risks of bias to a much greater extent than suggested by reporting rates obtained through systematic reviews. However, the researchers' self-reports are likely biased to some extent. Thus, although they claimed to be reporting measures against risks of bias at much lower rates than they claimed to be using these measures, the self-reported reporting rates were considerably higher than reporting rates found by systematic reviews. Furthermore, participants performed rather poorly when asked to

    in Australia, models of maternity care that offer women continuity of care with a known midwife have been promoted. Little is known about the intentions of the future midwifery workforce to work in such models. This study aimed to explore midwifery students' views and experiences of caseload midwifery and their work intentions in relation to the caseload model following graduation. cross-sectional survey. Victoria, Australia. 129 midwifery students representing all midwifery course pathways (Post Graduate Diploma, Bachelor of Midwifery, Bachelor of Nursing/Bachelor of Midwifery) in Victoria. midwifery students from all course pathways considered that continuity of care is important to women and indicated that exposure to continuity models during their course was very positive. Two-thirds of the students (67%) considered that the continuity experiences made them want to work in a caseload model; only 5% reported that their experiences had discouraged them from continuity of care work in the future. Most wanted a period of consolidation to gain experience as a midwife prior to commencing in the caseload model. Perceived barriers to caseload work were being on-call, and challenges in regard to work/life balance and family commitments. midwifery students in this study were very positive about caseload midwifery and most would consider working in caseload after a period of consolidation. Continuity of care experiences during students' midwifery education programmes appeared to provide students with insight and understanding of continuity of care for both women and midwives. Further research should explore what factors influence students' future midwifery work, whether or not their plans are fulfilled, and whether or not the caseload midwifery workforce can be sustained.

    Full Text Available Abstract Background Japanese men who have sex with men (MSM, especially those living in large metropolitan areas such as Tokyo and Osaka, are facing a growing HIV/AIDS epidemic. Although the Internet is used as a new venue for meeting sex partners, it can also serve as a useful research tool for investigating the risk behaviours of Japanese MSM. This Internet survey explored the extent of substance use and its association with sexual risk behaviours among Japanese MSM. Methods Between 28 February 2003 and 16 May 2003 MSM were recruited through 57 Japanese gay-oriented Web sites, gay magazines, and Internet mailing lists. Participants completed a structured questionnaire anonymously through the Internet. Results In total, 2,062 Japanese MSM completed the questionnaire. The average age of participants was 29.0 years and 70.5% identified as gay, 20.8% as bisexual, and 8.7% as other. Overall, 34.5% reported never using a substance, 45% reported ever using one type of substance (lifetime reported single substance users, and 19.6% had used more than 1 type of substance (lifetime reported multiple substance users in their lifetimes. The substances most commonly used were amyl nitrite (63.2%, 5-methoxy-N, N-diisopropyltryptamine (5MEO-DIPT (9.3%, and marijuana (5.7%. In the multivariate analysis, unprotected anal intercourse, having had 6 or more sexual partners, visiting a sex club/gay venue in the previous 6 months, a lower education level, and being 30 to 39 years of age were associated with both lifetime single and lifetime multiple substance use. Lifetime reported multiple substance use was also correlated with having a casual sex partner, having symptoms of depression, being diagnosed as HIV-positive, and greater HIV/AIDS-related knowledge. Conclusion This is the first Internet-based research focused on the sexual and substance use behaviours of MSM in Asia. Our findings suggest a compelling need for prevention interventions to reduce HIV risk

    Follow-through experiences (which enable midwifery students to experience continuity of care with individual women through pregnancy, labour and birth and the postnatal period) are a component of midwifery education programmes in Australia and the United Kingdom. Current accreditation standards in Australia require midwifery students to have a total of 20 continuity of care experiences with an average of 20 hours per woman over the duration of their course. There has been limited research regarding students' and academics' experiences of follow-through experiences; and there has been debate regarding the appropriate number of follow-through experiences in midwifery curricula. This study aimed to explore the follow-through experience from the perspective of midwifery students and academics in Victoria, Australia. cross-sectional design using a web-based survey. Victoria, Australia. Students (n=401) and academics (n=35) from all seven universities in Victoria that offer accredited midwifery programmes including the Bachelor of Midwifery, Bachelor of Nursing/Bachelor of Midwifery double degree, Postgraduate Diploma of Midwifery and Masters of Midwifery (entry to practice). Students and academics were in agreement that continuity of care is important to women. They considered the follow-through experience to be a unique and valuable learning opportunity and agreed that follow-through experiences should be included in midwifery education programmes. However, students and academics raised major concerns about the impact of follow-through experiences on students' capacity to meet university course requirements (such as missing lectures/tutorials and clinical placements), and spending extensive periods of time on-call both within and outside the university semester. Students and academics also reported concerns about the impact of follow-through experiences on students' personal lives, including paid employment and family responsibilities (such as childcare or caring for

Elimination of Onchocerca volvulus transmission was declared in 2015 after a three year post MDA surveillance period (2012-2014 showed no evidence of recrudescence. The purpose of the present study was to evaluate the knowledge, attitudes and practices (KAP towards onchocerciasis and ivermectin among residents in the post endemic CEZ. A major interest in this study was to determine what community residents thought about the end of the ivermectin MDA program.A total of 148 interviews were conducted in November 2014 in four formerly hyperendemic communities using a standard questionnaire on smart phones. The majority (69% of respondents knew that the MDA program had ended because the disease was no longer present in their communities, but a slight majority (53% was personally unsure that onchocerciasis had really been eliminated. Sixty-three percent wanted to continue to receive ivermectin because of this uncertainty, or because ivermectin is effective against intestinal worms. Eighty-nine percent of respondents said that they would seek medical attention immediately if a family member had symptoms of onchocerciasis (especially the presence of a nodule, which is a finding very important for ongoing surveillance.Many respondents wanted to continue receive ivermectin and more than half did not believe onchocerciasis had been eliminated. The ministry of health outreach services should be prepared to address ongoing concerns about onchocerciasis in the post endemic CEZ.

    The U.S. Department of Energy (DOE) Fuel Cell Technologies Program (FCT) conducts comprehensive efforts to enable the widespread commercialization of fuel cells in diverse sectors of the economy - with emphasis on applications that will most effectively strengthen our nation's energy security and improve our stewardship of the environment. Expanding the use of fuel cells requires a sustained education effort to lay the foundation for future commercial market introduction. The FCT education subprogram seeks to facilitate fuel cell demonstrations and support future commercialization by providing technically accurate and objective information to key target audiences both directly and indirectly involved in the use of fuel cells today. These key target audiences include a public that is familiar and comfortable with using a new fuel, state and local government officials who understand the near-term realities and long-term potential of the technology, an educated business and industry component, and trained safety and codes officials. With this in mind, the DOE FCT program established an education key activity to address the training and informational needs of target audiences that have a role in the near-term transition and the long-term development of a hydrogen economy. Whether or not changes can be attributed to the program, designing and maintaining an effective education program entails measuring baseline awareness and periodically measuring what has been learned. The purpose of this report is to document the data and results of statistical surveys undertaken in 2008 and 2009 to measure and establish changes in understanding and awareness about hydrogen and fuel cell technologies since a baseline survey was conducted in 2004. This report is essentially a data book, a digest of the survey data and an exposition of changes in knowledge of and opinions about hydrogen and fuel cell technology since 2004. Many conclusions can be made from the survey data. However

    Cancer screening participation rates in Germany differ depending on patients' gender. International studies have found that patient-physician gender concordance fosters recommendation and conducting of cancer screening, and especially cancer screening for women. We aimed to ascertain whether gender concordance influences general practitioners' (GPs') rating of the usefulness of cancer screening, as well as their recommendations and readiness to conduct cancer screening in general practice in Germany. For an exploratory cross-sectional survey, 500 randomly selected GPs from all over Germany were asked to fill in a questionnaire on cancer screening in general practice between March and June 2015. We asked them to rate the usefulness of each cancer screening examination, how frequently they recommended and conducted them and whether they viewed GPs or specialists as responsible for carrying them out. We used multiple logistic regression to analyse gender effect size by calculating odds ratios. Our study sample consisted of 139 GPs of which 65% were male. Male and female GPs did not differ significantly in their rating of the general usefulness of any of the specified cancer screening examinations. Male GPs were 2.9 to 6.8 times as likely to consider GPs responsible for recommending and conducting PSA testing and digital rectal examinations and were 3.7 to 7.9 times as likely to recommend and conduct these examinations on a regular basis. Patient-physician gender concordance made it more likely that male-specific cancer screenings would be recommended and conducted, but not female-specific screenings. [Box: see text].

    To determine the feasibility of using social media to perform cross-sectional epidemiologic and quality-of-life research on patients with rare gynecologic tumors, we performed a survey of patients with neuroendocrine tumors of the cervix using Facebook. After approval from our Institutional Review Board, a support group of patients with neuroendocrine tumors of the cervix was identified on Facebook. Group members were asked to complete a survey comprising 84 questions evaluating clinical presentation; treatment; recurrence; quality of life; and sexual function. The survey was posted for 30 days, during which 57 women responded from 8 countries across 4 continents treated at 51 centers. All respondents provided a detailed clinical and tumor history. The mean age was 38.5 years. The stage distribution was stage I, 36 patients (63%); II, 13 (23%); III, 2 (4%); and IV, 6 (11%). Forty-nine patients (86%) had small cell and 8 (14%) had large cell tumors. Forty-five of the respondents (79%) had completed primary therapy and were without evidence of disease. Five (9%) had recurrence, 3 (5%) had persistent disease after therapy, and 4 (7%) were still under treatment. Forty-one patients (72%) reported symptoms at time of presentation. Thirty-seven patients (65%) received multimodality primary therapy. Quality of life instruments demonstrated high scores for anxiety and a negative impact of anxiety and cancer on functional and emotional well-being. Sexual function scores did not differ significantly between respondents and the PROMIS reference population. Use of a social media network to perform epidemiologic and quality of life research on patients with rare gynecologic tumors is feasible and permits such research to be conducted efficiently and rapidly. © 2013.

    Lot Quality Assurance Sampling (LQAS) is a classification method that enables local health staff to assess health programmes for which they are responsible. While LQAS has been favourably reviewed by the World Bank and World Health Organization (WHO), questions remain about whether using local health staff as data collectors can lead to biased data. In this test-retest research, Pallisa Health District in Uganda is subdivided into four administrative units called supervision areas (SA). Data collectors from each SA conducted an LQAS survey. A week later, the data collectors were swapped to a different SA, outside their area of responsibility, to repeat the LQAS survey with the same respondents. The two data sets were analysed for agreement using Cohens' kappa coefficient and disagreements were analysed. Kappa values ranged from 0.19 to 0.97. On average, there was a moderate degree of agreement for knowledge indicators and a substantial level for practice indicators. Respondents were found to be systematically more knowledgeable on retest indicating bias favouring the retest, although no evidence of bias was found for practices indicators. In this initial study, using local health care providers to collect data did not bias data collection. The bias observed in the knowledge indicators is most likely due to the 'practice effect', whereby respondents increased their knowledge as a result of completing the first survey, as no corresponding effect was seen in the practices indicators.

    Objective The Internet is a widespread source of health information for health-care professionals and patients. Social inequalities in Internet access have been well studied but not practices. This study was conducted to determine whether differences exist in the frequency of Internet use for health information among online health seekers. Methods We conducted an Internet-based survey from November 2006 to March 2007. The 3720 residents of France who had searched for health information during the previous year were considered. Results This study reveals different practice of online health information seeking between men, women, the general population and people who work in the health sector. Health status and active Internet use were associated with higher frequencies to varying degrees. Greater health concerns and some issues in the physician-patient relationship were associated with higher frequencies of Internet use in the general population. Conclusions The Internet seems to be used as a substitute information tool when issues of communication or confidence with physicians arise as well as to lead people to question physicians and medicine. Practical implications Physician and public health actors should remain cautious about these disparities in online health information seeking access and practices, quality issues concerning online information and about possible self-exclusion from the health-care system.

    Full Text Available The Brazilian HIV/AIDS epidemic is concentrated among men who have sex with men (MSM, however HIV testing rates among MSM are not commensurate with their risk. Strategies to expand early diagnosis may include use of self-conducted home-based testing kits, which are now available for purchase in the US. In April 2011 we conducted a survey with Brazilian MSM using Facebook to assess HIV testing preferences and acceptability of home-based testing. Among 356 previously tested, HIV-negative MSM, 47% reported a preference for home-based testing, 27% preferred clinic-based testing, and 26% had no preference. Less frequent testers and those who had considered testing but failed to test were more likely to prefer home-based testing. Close to 90% reported that they would use self-test kits; 62% and 54% said they would use home-based testing to make choices about unprotected sex with regular and new partners, respectively. Concerns included difficulty to understand the tests (32% and receiving results alone (23%. Overall, home-based testing may appeal to MSM and result in increased testing frequency. Research on feasibility and utilization of self-tests in practice is needed.

    It is now known that resident doctors registered for postgraduate studies are prone to work related stress and eventual burnout. Though stress can happen in any profession, reduced performance of resident doctors due to vocational stress could cause an increase in medical errors and thus affect the quality of life of the patients. Resident doctors at a Municipal hospital in India form a unique population as number of stresses they undergo are many and varied. To study the prevalence of work-related stress and its anticipated solutions among the resident doctors registered for postgraduate studies in clinical subjects at a tertiary Municipal hospital. A stratified sampling cross-sectional survey was conducted at the Inpatient, Outpatient, and Intensive Care Units at a tertiary Municipal hospital in Mumbai, India. Data collection was done using a validated 20-point questionnaire to assess the factors causing stress and their anticipated solutions. Simple percentage analysis of stress questionnaire. 71 resident doctors completed the survey. The major stressors in this cohort were inadequate hostel/quarter facilities (92.1%), and the need to perform extra duties (80.0%). Also, non-conducive environment for clinical training and studies (81.7%), inadequate study (78.9%) and break (81.2%), threat from deadly infections (74.6%), and overburdening with work (69.0%) were the other major stress causing factors. The perceived stress busters were good music (40.8%) and family and friends (40.8%). Eighty-seven percent of the respondents perceived regular physical exercise to be an effective mode of stress management and 83.8% expressed their need to have a simple therapeutic gymnasium established within the campus with a qualified trainer. There is a high level of work related stress among the resident doctors registered for postgraduate clinical studies at a tertiary Municipal hospital in Mumbai. One of the perceived stress busters is regular physical exercise that is

    Background Nonadherence is common among patients with schizophrenia, although the rates vary according to means of assessment and patient population. Failure to adhere to medication can have a major impact on the course of illness and treatment outcomes, including increasing the risk of relapse and rehospitalization. Understanding psychiatrists’ perception of the causes and consequences of nonadherence is crucial to addressing adherence problems effectively. Methods The Europe, the Middle East, and Africa (EMEA) Spanish Adherencia Terapéutica en la Esquizofrenia (ADHES) survey was conducted by questionnaire during January–March 2010 among psychiatrists treating patients with schizophrenia in 36 countries. The survey comprised 20 questions. In addition to recording the demographic details of the 4722 respondents (~12% response rate), it canvassed their preferred methods of assessing adherence, their perceptions of adherence rates, reasons for nonadherence, and strategies to improve adherence. Results Psychiatrists estimated that 53% of their patients with schizophrenia were partially/nonadherent during the previous month. They estimated only one-third of patients who deteriorated after stopping medication were able to attribute this to nonadherence. Psychiatrists assessed adherence most often by patient interview. Lack of insight was viewed as the most important cause of medication discontinuation, followed by patients feeling better and thinking their medication unnecessary, and experiencing undesirable side effects. Considerably fewer psychiatrists viewed insufficient efficacy, cognitive impairment, or drug/alcohol abuse as the most important reasons for their patients stopping medication. Conclusion Psychiatrists throughout EMEA recognize the impact of partial/nonadherence to medication, with patient enquiry being the most commonly used means of assessment. There remains a need for more proactive management of patients with schizophrenia, particularly in

In addition to recording the demographic details of the 4722 respondents (~12% response rate, it canvassed their preferred methods of assessing adherence, their perceptions of adherence rates, reasons for nonadherence, and strategies to improve adherence.Results: Psychiatrists estimated that 53% of their patients with schizophrenia were partially/nonadherent during the previous month. They estimated only one-third of patients who deteriorated after stopping medication were able to attribute this to nonadherence. Psychiatrists assessed adherence most often by patient interview. Lack of insight was viewed as the most important cause of medication discontinuation, followed by patients feeling better and thinking their medication unnecessary, and experiencing undesirable side effects. Considerably fewer psychiatrists viewed insufficient efficacy, cognitive impairment, or drug/alcohol abuse as the most important reasons for their patients stopping medication.Conclusion: Psychiatrists throughout EMEA recognize the impact of partial/nonadherence to medication, with patient enquiry being the most commonly used means of assessment. There remains a need for more proactive management of patients with schizophrenia, particularly in increasing patient insight of their illness in order to improve adherence and minimize the consequences of relapse. Strategies focused on raising awareness of the importance of adherence are also warranted, with the aim of improving patient outcomes in schizophrenia.Keywords: adherence, schizophrenia, psychiatrist, survey, ADHES

    The objective of this prospective study was to describe the nature of the lesions observed during brain-dead cadavre donor kidney harvesting in France and to identify the risk factors for these lesions. A questionnaire elaborated by the AFU Transplantation Committee concerning the quality of kidneys harvested from cadavre donors was sent to all centres performing renal transplantation in France in 2000. This prospective study was conducted over a period of 1 year and concerned the overall multi-organ harvesting procedure based on all data concerning the renal parenchyma, arteriovenous and ureteric characteristics, and the outcome of the transplants. Twelve centres completed the survey, allowing analysis of the data of 201 donor kidneys. 91% of harvesting surgeons were urologists. Various incidents were reported during 11% of harvesting procedures, but 1/3 of the abnormalities were not recorded by the harvesting surgeon. Isolated kidney harvesting was found to be a risk factor (20% vs 8.6%). The rate of parenchymal abnormalities was 50%, 2/3 of which were related to inadequate removal of perirenal fat. Atheroma was a risk factor for arterial lesions during harvesting (21% vs 6.50). Venous abnormalities were detected in 9% of cases: 89% of them were due to the harvesting procedure and 59% of them were not identified by the harvesting surgeon. The fact of not being a transplant surgeon was a risk factor for venous lesions (21.9% vs 6.5%). 4% of ureteric lesions were observed with no consequence on graft outcome. Adequate removal of perirenal fat before conditioning is not acquired. Isolated kidney harvesting and atheroma were risk factors for parenchymal and arterial lesions, respectively. Venous harvesting anomalies were more frequent among non-transplant surgeons.

    There is a dearth of research examining the linkages between violence and HIV risk behavior among men who have sex with men (MSM), including those who identify as transgender women (TW), particularly in Central America where violence is widespread. In this paper, we use population-based survey results to independently examine the correlations between physical, emotional and sexual violence and HIV risk behavior among MSM populations in five countries in Central America. As part of USAID's Combination Prevention for HIV program in Central America, PASMO conducted population based surveys using respondent-driven sampling (RDS) in nine cities in Guatemala, El Salvador, Nicaragua, Costa Rica, and Panama. Initial seeds were recruited using the following criteria: individuals who represented subgroups of MSM by self-identification (homosexual vs. heterosexual or bisexual vs. transgender), social economic strata, and by sex work practices. This study examines the association between violence and 1) HIV risk behaviors relevant to the study populations; 2) protective behaviors; and 3) reported STIs. Individualized RDS estimator weights for each outcome variable were calculated using RDSAT software, and logistic regression analysis was used to determine associations between different forms of violence and the outcome variables. MSM who experienced physical violence were more likely to be engaged in transactional sex (OR: 1.76 [1.42-2.18]), have multiple partners in the past 30 days (OR: 1.37 [1.09-1.71]), and have engaged in sex under the influence of alcohol or drugs (OR: 1.51 [1.24-1.83]). Both physical violence and psychological/verbal violence were also associated with reporting STI symptoms or diagnosis within the past 12 months (OR: 1.72 [1.34-2.21] and 1.80 [1.45-2.23]). The effects of violence on the outcomes were observed after controlling for other risk factors. Transgender women were 3.9 times more likely to report engaging in transactional sex. Respondents who

    Indonesia has high levels of biological need for infertility treatment, great sociological and psychological demand for children, and yet existing infertility services are underutilized. Access to adequate comprehensive reproductive health services, including infertility care, is a basic reproductive right regardless of the economic circumstances in which individuals are born into. Thus, identifying and implementing strategies to improve access to assisted reproductive technology (ART) in Indonesia is imperative. The principle objectives of this article are to improve our understanding of infertility patients' patterns of health seeking behaviour and their patterns of access to infertility treatment in Indonesia, in order to highlight the possibilities for improving access. An interviewer-administered survey was conducted with 212 female infertility patients recruited through three Indonesian infertility clinics between July and September 2011. Participants were self-selected and data was subject to descriptive statistical analysis. Patients identified a number of barriers to access, including: low confidence in infertility treatment and high rates of switching between providers due to perceived treatment failure; the number and location of clinics; the lack of a well established referral system; the cost of treatment; and patients also experienced fear of receiving a diagnosis of sterility, of vaginal examinations and of embarrassment. Women's age of marriage and the timing of their initial presentation to gynaecologists were not found to be barriers to timely access to infertility care. The findings based on the responses of 212 female infertility patients indicated four key areas of opportunity for improving access to infertility care. Firstly, greater patient education about the nature and progression of infertility care was required among this group of women. Secondly, increased resources in terms of the number and distribution of infertility clinics would

    On the surface, it would appear that patients would welcome the opportunity to relinquish their traditional subordination to doctors in therapeutic decision making, and that doctors would be pleased to have partners with whom to share the burden involved in making such fateful decisions. We investigated the attitudes and practices of patients and physicians towards "patient autonomy" in an outpatient clinic of an internal medicine department prior to the enactment of the Patient's Rights Bill in Israel. There were 81 patients randomly chosen from those attending the study clinic and 21 physicians randomly selected from among the physicians treating them. They were all administered the Krantz, the Abramson Health Index, and the Christie Ethical Decision Making pre-tested questionnaires. They were also queried on demographic and background material. The results indicated that the patient sample was neither particularly interested in participating in medical decision making (average score of 3 out of 9 in the Krantz behavioral involvement sub-scale) nor in receiving medical information (average score of 4 out of 7 in the Krantz preference of information sub-scale). The physicians exhibited a willingness to establish equal relations with their patients, and claimed to prefer their taking an active role in decision making. However, when presented with ethical dilemmas, the physicians were not consistent in their attitude in terms of respecting "patient autonomy." The findings of an Israeli survey conducted three years after the bill's passage showed that only one-third of the studied physicians had read the Israel Medical Association booklet's explaining the new law and most of them claimed that the new law had no affect on their daily encounter with patients, meaning that the law did not affect any change in these physicians' pattern of behavior. We concluded that if the Patient's Rights Bill is to achieve its goals, it will have to be accompanied by a widespread

    The Philippines has a long history of rabies control efforts in their dog populations; however, long-term success of such programmes and the goal of rabies elimination have not yet been realized. The Bohol Rabies Prevention and Elimination Program was developed as an innovative approach to canine rabies control in 2007. The objective of this study was to assess canine rabies vaccination coverage in the owned-dog population in Bohol and to describe factors associated with rabies vaccination 2 years after implementation of the programme. We utilized a cross-sectional cluster survey based on the World Health Organization's Expanded Programme on Immunization coverage survey technique. We sampled 460 households and collected data on 539 dogs residing within these households. Seventy-seven per cent of surveyed households reported owning at least one dog. The human-to-dog ratio was approximately 4 : 1, and the mean number of dogs owned per household was 1.6. Based on this ratio, we calculated an owned-dog population of almost 300 000. Overall, 71% of dogs were reported as having been vaccinated for rabies at some time in their lives; however, only 64% of dogs were reported as having been recently vaccinated. Dogs in our study were young (median age = 24 months). The odds of vaccination increased with increasing age. Dogs aged 12-23 months had 4.6 times the odds of vaccination compared to dogs aged 3-11 months (95% CI 1.8-12.0; P = 0.002). Confinement of the dog both day and night was also associated with increased odds of vaccination (OR = 2.1; 95% CI 0.9-4.9; P = 0.07), and this result approached statistical significance. While the programme is on track to meet its goal of 80% vaccination coverage, educational efforts should focus on the need to confine dogs and vaccinate young dogs. © 2012 Blackwell Verlag GmbH.

  5. Short-eared Owl (Asio flammeus surveys in the North American Intermountain West: utilizing citizen scientists to conduct monitoring across a broad geographic scale

    Full Text Available The Short-eared Owl (Asio flammeus is an open-country species breeding in the northern United States and Canada, and has likely experienced a long-term, range-wide, and substantial decline. However, the cause and magnitude of the decline is not well understood. We set forth to address the first two of six previously proposed conservation priorities to be addressed for this species: (1 better define habitat use and (2 improve population monitoring. We recruited 131 volunteers to survey over 6.2 million ha within the state of Idaho for Short-eared Owls during the 2015 breeding season. We surveyed 75 transects, 71 of which were surveyed twice, and detected Short-eared Owls on 27 transects. We performed multiscale occupancy modeling to identify habitat associations, and performed multiscale abundance modeling to generate a state-wide population estimate. Our results suggest that within the state of Idaho, Short-eared Owls are more often found in areas with marshland or riparian habitat or areas with greater amounts of sagebrush habitat at the 1750 ha transect scale. At the 50 ha point scale, Short-eared Owls tend to associate positively with fallow and bare dirt agricultural land and negatively with grassland. Cropland was not chosen at the broader transect scale suggesting that Short-eared Owls may prefer more heterogeneous landscapes. On the surface our results may seem contradictory to the presumed land use by a "grassland" species; however, the grasslands of the Intermountain West, consisting largely of invasive cheatgrass (Bromus tectorum, lack the complex structure shown to be preferred by these owls. We suggest the local adaptation to agriculture represents the next best habitat to their historical native habitat preferences. Regardless, we have confirmed regional differences that should be considered in conservation planning for this species. Last, our results demonstrate the feasibility, efficiency, and effectiveness of utilizing public

    The U.S. Geological Survey (USGS), in cooperation with Region III of the U.S. Environmental Protection Agency (USEPA) and the State of Delaware, is conducting an ongoing study of the water-quality and hydrogeologic properties of the Columbia and Potomac aquifers and the extent of cross-aquifer contamination with benzene; chlorobenzene; 1,2-dichlorobenzene; 1,4-dichlorobenzene; and hydrogen chloride (hydrochloric acid when dissolved in water) in the vicinity of the Standard Chlorine of Delaware, Inc. (SCD), Superfund Site, Delaware City, Delaware. Surface geophysical surveys and well data were used to identify and correlate low-permeability units (clays) across the site and to search for sand and gravel filled paleochannels that are potential conduits and receptors of contaminated groundwater and (or) Dense Non-Aqueous Phase Liquid (DNAPL) contaminants. The combined surveys and well data were also used to characterize areas of the site that have groundwater with elevated (greater than 1,000 microsiemens per centimeter) specific conductance (SC) as a result of contamination. The most electrically conductive features measured with direct-current (DC) resistivity at the SCD site are relatively impermeable clays and permeable sediment that are associated with elevated SC in groundwater. Many of the resistive features include paleochannel deposits consisting of coarse-grained sediments that are unsaturated, have low (less than 200 microsiemens per centimeter) SC pore water, or are cemented. Groundwater in uncontaminated parts of the Columbia aquifer and of the Potomac aquifer has a low SC. Specific-conductance data from monitoring wells at the site were used to corroborate the DC-resistivity survey results. For comparison with DC-resistivity surveys, multi-channel analysis of surface wave (MASW) surveys were used and were able to penetrate deep enough to measure the Columbia aquifer, which is known to have elevated SC in some places. MASW survey results respond to solid

    Full Text Available The paper presents the state of fruit producers’ knowledge, as well as methods of EU support application under the various programmes available in both the period before and after Poland’s accession to the EU. Farmers, including gardeners, could apply for funding under the SAPARD programme already before the accession. These grants were the beginning of the support Poland received during this period. EU aid became applied on a large scale just after the accession. A large part of manufacturers began to apply for support i.a. under the Rural Development Programme for 2007–2013 (hereinafter RDP 2007–2013. The survey involved 103 fruit producers from the Grójec County, which is the area of greatest importance in the Polish fruit production. Nearly three quarters of the surveyed respondents claimed that they had benefi ted from the EU support. Those producers who benefi ted from the RDP 2007–2013, the granted funds in 63% invested in modernizing their farms. A lot of producers the received funds earmarked for the purchase of machines. Preferential loans also gained in popularity, especially those that could be applied for after disasters which had destroyed growers’ crops, e.g. spring ground frost, hail etc. 30% of respondents benefi ted from this type of support. It is worth emphasising that almost three quarters of the respondents obtained assistance in making applications from private companies, and not from the state institutions. The biggest obstacle encountered by the producers when applying for EU funds, was the intricate procedure in fi lling in the applications.

    High N loss and low N use efficiency (NUE), caused by high N fertilizer inputs and inappropriate fertilization patterns, have become important issues in the rice (Oryza sativa L.) growing regions of southern China. Changing current farmer fertilizer practice (FFP, 225 kg ha-1 N as three applications, 40% as basal fertilizer, 30% as tillering fertilizer and 30% as jointing fertilizer) to one-time root-zone fertilization (RZF, 225 kg ha-1 N applied once into 10 cm deep holes positioned 5 cm from the rice root as basal fertilizer) will address this problem. A two-year field experiment covering two rice growing regions was conducted to investigate the effect of urea one-time RZF on rice growth, nutrient uptake, and NUE. The highest NH4+-N content for RZF at fertilizer point at 30 d and 60 d after fertilization were 861.8 and 369.9 mg kg-1 higher than FFP, respectively. Rice yield and total N accumulation of RZF increased by 4.3-44.9% and 12.7-111.2% compared to FFP, respectively. RZF reduced fertilizer-N loss by 56.3-81.9% compared to FFP. The NUEs following RZF (mean of 65.8% for the difference method and 43.7% for the labelled method) were significantly higher than FFP (mean of 35.7% for the difference method and 14.4% for the labelled method). In conclusion, RZF maintained substantial levels of fertilizer-N in the root-zone, which led to enhanced rice biomass and N uptake during the early growth stages, increased fertilizer-N residual levels and reduced fertilizer-N loss at harvest. RZF produced a higher yield increment and showed an increased capacity to resist environmental threats than FFP in sandy soils. Therefore, adopting suitable fertilizer patterns plays a key role in enhancing agricultural benefits.

    We have continued to develop a concept for use of autonomous rovers, originally developed for use in planetary exploration, in polar science on Earth; the concept was the subject of a workshop, and this report summarizes and extends that workshop. The workshop on Antarctic Autonomous Scientific Vehicles and Traverses met at the National Geographic Society on February 14 and 15, 2001 to discuss scientific objectives and benefits of the use of autonomous rovers. The participants enthusiastically viewed rovers as being uniquely valuable for such tasks as data taking on tedious or repetitive routes, traverses in polar night, difficult or hazardous routes, extremely remote regions, routes requiring only simple instrumentation, traverses that must be conducted at low speed, augments of manned traverses, and scientific procedures not compatible with human presence or combustion engines. The workshop has concluded that instrumented autonomous vehicles, of the type being developed for planetary exploration, have the potential to contribute significantly to the way science in conducted in Antarctica while also aiding planetary technology development, and engaging the public's interest. Specific objectives can be supported in understanding ice sheet mass balance, sea ice heat and momentum exchange, and surface air chemistry processes. In the interval since the workshop, we have concluded that organized program to employ such rovers to perform scientific tasks in the Fourth International Polar Year would serve the objectives of that program well.

    To assess the working styles of men and women working as surgeons in Japan. In July, 2014, the Japan Surgical Society invited all their members (n = 29,861), through an internet campaign, to participate in a nationwide survey of surgeons. The items investigated in this descriptive study included demographic information and working styles, based on a questionnaire. In total, 6211 surgeons participated (response rate 20.8%, 5586 men and 625 women). The largest age stratum was 40-49 years for men and 30-39 years for women. Overall, respondents identified their labor contract, including salary and work hours, as the highest priority for improvement. Women with children were more likely to be part-time employees, work fewer hours, and take fewer house calls/on-calls than their male counterparts. Moreover, women of all ages earned a lower annual income than men, irrespective of whether they had children. Perception scores for discrimination related to work and promotion were significantly higher among women than men (p women working as surgeons in Japan.

    To assess the true conditions and perceptions of the personal lives of men and women working as surgeons in Japan. In 2014, all e-mail subscribed members of the Japan Surgical Society (JSS, n = 29,861) were invited to complete a web-based survey. The questions covered demographic information, work environment, and personal life (including marital status, childcare, and nursing care for adult family members). In total, 6211 surgeons (5586 men and 625 women) returned the questionnaires, representing a response rate of 20.8%. Based on the questionnaire responses, surgeons generally prioritize work and spend most of their time at work, although women with children prioritize their family over work; men spend significantly fewer hours on domestic work/childcare than do their female counterparts (men 0.76 h/day vs. women 2.93 h/day, p differed significantly according to gender and whether they have children.

    Full Text Available Background: Rational nutrition management in infants under 3 years is an important part of their adequate development at this age and in future.Objective: Our aim was to evaluate awareness of pediatricians and parents concerning rational nutrition management in infants under 3 years.Methods: 300 pediatricians and 300 parents of infants under 3 years who live in Moscow, Ivanovo, and Yaroslavl were enrolled in pilot survey.Results: Pediatricians' recommendations on child nutrition management satisfied the majority of parents (252; 84%, however, less than half of families (135; 45% followed them. In other cases the child's ration depended on mother's opinion on the matter (96; 32% and on child's food preference. «Unhealthy» food such as groceries and provision, processed food, spices, seafood, fast food, chocolate, candies, and sweets as well as soda was included in child's ration at the age of 2 and its consumption frequency increased significantly at the age of 3. Pediatricians strongly recommended special dairy for infants from the age of 1 (known as the 3rd formula. In fact, only half of children in Moscow eat them, and 27–30% of children in Ivanovo and Yaroslavl.Conclusion: Harmful breach of nutrition management in infants under 3 years is detected. Evidently, parents are not competent on the question. Optimization of educational activities performed by pediatricians, medical stuff, and mass media is required.

    Traditional Japanese (Kampo) medicine has been widely applied in general medicine in Japan. In 2001, the model core curriculum for Japanese medical education was revised to include Kampo medicine. Since 2007, all 80 Japanese medical schools have incorporated it within their programs. However, postgraduate training or instruction of Kampo medicine has not been recognized as a goal for the clinical training of junior residents by Japan's Ministry of Health, Labour and Welfare; little is known about postgraduate Kampo medicine education. This exploratory study investigated attitudes about Kampo medicine among junior residents in Japanese postgraduate training programs. A questionnaire survey was administered to junior residents at five institutions in the Tohoku area of Japan. Questions evaluated residents' experiences of prescribing Kampo medicines and their expectations for postgraduate Kampo education and training. As a result, 121 residents responded (response rate = 74%). About 96% of participants had previously received Kampo medicine education at their pre-graduate medical schools and 64% had prescribed Kampo medications. Specifically, daikenchuto was prescribed to prevent ileus and constipation after abdominal surgery and yokukansan was prescribed to treat delirium in the elderly. Residents received on-the-job instruction by attending doctors. Over 70% of participants indicated that there was a need for postgraduate Kampo medicine education opportunities and expected lectures and instruction on how to use it to treat common diseases. In conclusion, we have revealed that junior residents require Kampo medicine education in Japanese postgraduate training programs. The programs for comprehensive pre-graduate and postgraduate Kampo education are expected.

    RESEARCH SIGNIFICANCE: Job insecurity, the subjective individual anticipation of involuntary job loss, negatively affects employees' health and their engagement. Although the relationship between job insecurity and health has been extensively studied, job insecurity as an 'exposure' has received far less attention, with little known about the upstream determinants of job insecurity in particular. This research sought to identify the relationship between self-rated job insecurity and area-level unemployment using a longitudinal, nationally representative study of Australian households. Mixed-effect multi-level regression models were used to assess the relationship between area-based unemployment rates and self-reported job insecurity using data from a longitudinal, nationally representative survey running since 2001. Interaction terms were included to test the hypotheses that the relationship between area-level unemployment and job insecurity differed between occupational skill-level groups and by employment arrangement. Marginal effects were computed to visually depict differences in job insecurity across areas with different levels of unemployment. Results indicated that areas with the lowest unemployment rates had significantly lower job insecurity (predicted value 2.74; 95% confidence interval (CI) 2.71-2.78, P unemployment (predicted value 2.81; 95% CI 2.79-2.84, P unemployment and job insecurity among precariously and fixed-term employed workers than permanent workers. These findings demonstrate the independent influences of prevailing economic conditions, individual- and job-level factors on job insecurity. Persons working on a casual basis or on a fixed-term contract in areas with higher levels of unemployment are more susceptible to feelings of job insecurity than those working permanently.

    Full Text Available This study reports the findings of resistivity surveys which were conducted at the initiation area of debris flow at KM 9, Fraser’s Hill Gap road (FT148. The study involves three slope parallel survey lines and two lines perpendicular to the slope face. The parallel lines are FH01, FH02, and FH03, while the lines FH04 and FH05 are perpendicular. A granite body was detected at the central part of the east line and is nearest to the ground surface along FH02. The existence of low resistivity zones within the granite body is interpreted as highly fractured, water conducting zones. These zones are continuous as they have been detected in both the east-west as well as the north-south lines. The residual soil layer is relatively thin at zones where weathered granite dominates the slope face of the failure mass. The weak layer is relatively thick with an estimated thickness of 80 m and water flow occurs at the base of it. The high water flow recorded from the horizontal drains further supports the possible existence of these highly fractured, water conducting zones located within the granite. The shallow fractured granite is virtually “floating” above the water saturated zone and therefore is considered unstable.

    To assess the prevalence of left ventricular hypertrophy according to electrocardiographic and echocardiographic criteria among hypertensive patients living in semi-rural Senegalese area. According to the World Health Organization STEPSwise approach, we conducted, in November 2012, a cross-sectional and exhaustive study in the population aged at least 35 years old and living for at least six months in the semi-rural area of Guéoul. We researched electrocardiographic and echocardiographic left ventricular hypertrophy in hypertensive subjects. Data were analyzed with SPSS 18.0 software version. The significance level was agreed for a value of P<0.05. We examined 1411 subjects aged on average of 48.5±12.7 years. In total, 654 subjects were hypertensive and screening of left ventricular hypertrophy (LVH) was effective in 515 of them. According to Sokolow-Lyon index, 86 subjects (16.7%) presented electrocardiographic LVH, more frequently in men (P=0.002). According to Cornell index and Cornell product, LVH was founded respectively in 66 (12.8%) and 52 subjects (10.1%), more frequently in female (P=0.0001; P=0.004). It was more common in grade 3 of hypertension however criteria. In echocardiography, prevalence of LVH was 2.2% (13 cases) according to the left ventricular mass, 9.3% (48 cases) according to the left ventricular mass indexed to body surface area and 8.2% (42 cases) according to the left ventricular mass indexed to height 2.7 . LVH was significantly correlated with the electrocardiographic LVH according to Sokolow-Lyon index (P<0.0001) and the grade 3 of hypertension (P=0.003). Although rare in hypertensive Senegalese living in semi-rural area, left ventricular hypertrophy is correlated with severity of grade of hypertension. Screening by electrocardiogram will allow better follow-up of these hypertensive subjects. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    This paper presents here the results of a survey conducted in summer 1992 at Guadalajara and Monterrey homes. The survey main objective was to examine the potential of the replacement of incandescent bulbs for fluorescent compact bulbs (FCBs) to save electricity. Additionally it was determined the saturation level of other electric home appliances. Considering the physical restrictions of lanterns, during the evening demand peak hours a maximum of about 3.6 million of FCBs can be introduced into the electric network between 8:00 and 9:00 Pm, economizing about 207 MW. It was found that the importance of lighting, the potential of FCBs and the equipment with electric home appliances varies significantly in accordance with the electricity consumption at home. Lighting represents at least about 22% and 14% of the total electricity consumption in the homes of Guadalajara and Monterrey, respectively. This percentage is higher among low electricity consumption users. The saturation in electrical home appliances demonstrated the importance of the refrigerators, TV sets, and air conditioning units (these ones only for Monterrey). In both cities about 1.5 TV sets and 0.96 refrigerators per home were reported. In Monterrey 0.4 air conditioning units and 1.6 electric fans per home were reported. In Guadalajara only about 0.5 fans per home were reported. The results of this survey show the importance of promoting programs to increase the energy efficiency to cover the lighting and refrigeration needs in both cities and air conditioning in Monterrey.

  1. Determination of hydraulic conductivity in three dimensions and its relation to dispersivity: Chapter D in Ground-water contamination by crude oil at the Bemidji, Minnesota, research site; US Geological Survey Toxic Waste--ground-water contamination study

    Science.gov (United States)

    1984-01-01

    Recent investigations suggest that dispersion in aquifers is scale dependent and a function of the heterogeneity of aquifer materials. Theoretical stochastic studies indicate that determining hydraulic-conductivity variability in three dimensions is important in analyzing the dispersion process. Even though field methods are available to approximate hydraulic conductivity in three dimensions, the methods are not generally used because of high cost of field equipment and because measurement and analysis techniques are cumbersome and time consuming. The hypothesis of this study is that field-determined values of dispersivity are scale dependent and that they may be described as a function of hydraulic conductivity in three dimensions. The objectives of the study at the Bemidji research site are to (1) determine hydraulic conductivity of the porous media in three dimensions, (2) determine field values of dispersivity and its scale dependence on hydraulic conductivity, and (3) develop and apply a computerized data-collection, storage, and analysis system for field use in comprehensive determination of hydraulic conductivity and dispersivity. Plans for this investigation involve a variety of methods of analysis. Hydraulic conductivity will be determined separately in the horizontal and vertical planes of the hydraulic-conductivity ellipsoid. Field values of dispersivity will be determined by single-well and doublet-well injection or withdrawal tests with tracers. A computerized data-collection, storage, and analysis system to measure pressure, flow rate, tracer concentrations, and temperature will be designed for field testing. Real-time computer programs will be used to analyze field data. The initial methods of analysis will be utilized to meet the objectives of the study. Preliminary field data indicate the aquifer underlying the Bemidji site is vertically heterogeneous, cross-bedded outwash. Preliminary analysis of the flow field around a hypothetical doublet

    We surveyed interpretation of the ICH guidelines concerning reproductive toxicology. Valid responses were obtained from Japan (JPN), Europe (EUR) and the U.S. The results obtained were compared to those at the time of a previous survey targeted at JPN facilities in 1995-1996 as well as compared among all three regions. Compared to the previous survey in Japan, the number of facilities performing toxicokinetics (TK) in rats has slightly increased. This result was considered to represent changes of attitude toward TK in reproductive toxicity studies. Differences in interpretation of the guidelines between JPN, EUR and the US were widely seen. Clear differences were noted in sperm examinations, postnatal tests, fetal examinations, some examinations for F1 animals after culling and TK. Researchers in the West seemed to be interpreting the ICH guidelines more flexibly from the scientific point of view. JPN researchers appeared to interpret the guidelines, including notes, as rigid requirements. Most of the parts which produced different interpretations were the notes in the guidelines. The force of mention in the notes should be defined in the future. In addition, there were doubts about some parts, including notes, which had been found to have become unsuitable for the implementation of studies because of scientific progress or from long experience in using the guidelines. Therefore, updates of the guidelines may be needed in the future as well as the remedy of interpretation by JPN researchers. In JPN, the number of reproductive toxicity studies has decreased. The scanty experience in JPN therefore raises apprehension of appropriate selection and stagnating development of methodology, and might hinder the maintenance of the guidelines. In the future, the cooperation of CROs as well as global collaboration will be essential not only to scientific developments of reproductive toxicology but also updates of the guidelines.

  6. Liver cancer mortality trends during the last 30 years in Hebei province: comparison results from provincial death surveys conducted in the 1970's, 1980's, 1990's and 2004-2005.

    Liver cancer is a major health problem in low-resource countries. Approximately 55% of all liver cancer occurs in China. Hebei Province is one of the important covering nearly 6% of the population of China. The aim of this paper was to explore liver cancer mortality trends during past 30 years, and provide basic information on prevention strategies. Hebei was covered covered all the three national surveys during 1973-1975, 1990-1992, and 2004-2005 and one provincial survey during 1984-1986. Subjects included all cases dying from liver cancer in Hebei Province. Liver cancer mortality trend and geographic differences across cities and counties were analyzed. There were 82,878 deaths in Hebei Province during 2004-2005 with an average mortality rate was 600.9/10,000, and an age-adjusted rate of 552.3/10,000. Those dying of cancer were 18,424 cases, accounting for 22.2% of all deaths, second only to cerebrovascular disease as a cause of death. Cancer mortality was 133.6/100,000 (age-adjusted rate was 119.2/100,000). Liver cancer ranked fourth in this survey with a mortality rate of 21.0/100,000, 28.4/100,000 in males and 13.35/10,000 in females, accounting for 15.7%, 17.1% and 13.4% of the total number of cancer deaths and in males and females, respectively. The sex ratio was 2.13. Since the 1970s, liver cancer deaths of Hebei province have been increasing slightly. The crude mortality rates in the four surveys were 11.3, 16.0, 17.4, 21.0 per 100,000, respectively, with age-adjusted rates fluctuating during the past 30 years, but the trend also being upwards. There is a tendency for the mortality rates to be higher in coastal than mountain areas, and is relative lower in the plain area, with crude mortality rates of 25.3, 22.1, and 19.1 per 100,000, respectively. There were no notable differences in cride data between urban and rural, but the age-adjusted mortality rate in rural was much higher. Our study indicated that the mortality of liver cancer in Hebei Province is

The flexibility of 1 has been also studied by means of TDXD (temperature dependent X-ray diffraction) evidencing remarkable phase transformations that lead to a different disposition of the water molecules. These transformations also influence the accessibility of the cations on the P-OH groups placed inside the channels and thus the ion-exchange properties. The dependence of the proton conductivity properties on these phase transitions has been also investigated and discussed.

    In the context of applications of the AdS/CFT correspondence to condensed matter physics, we compute conductivities for field theory duals of dyonic planar black holes in 3+1-dimensional Einstein-Maxwell-dilaton theories at zero temperature. We combine the near-horizon data obtained via Sen’s entropy function formalism with known expressions for conductivities. In this way we express the conductivities in terms of the extremal black hole charges. We apply our approach to three different examples for dilaton theories for which the background geometry is not known explicitly. For a constant scalar potential, the thermoelectric conductivity explicitly scales as α{sub xy}∼N{sup 3/2}, as expected. For the same model, our approach yields a finite result for the heat conductivity κ/T∝N{sup 3/2} even for T→0.

    Disclosed are several examples of a system and method for detecting if an article is being tampered with. Included is a covering made of a substrate that is coated with a layer of an electrically conductive material that forms an electrically conductive surface having an electrical resistance. The covering is configured to at least partially encapsulate the article such that the article cannot be tampered with, without modifying the electrical resistance of the electrically conductive surface of the covering. A sensing device is affixed to the electrically conductive surface of the covering and the sensing device monitors the condition of the covering by producing a signal that is indicative of the electrical resistance of the electrically conductive surface of the covering. A measured electrical resistance that differs from a nominal electrical resistance is indicative of a covering that is being tampered with and an alert is communicated to an observer.

    The dc conductivity of polycrystalline phosphatidylethanolamine (PE) was measured in the temperature range 60-120 degrees C. Since no conclusive evidence had so far been obtained for the presence of proteon conduction in this phospholipid, hydrogen gas was shown in the present experiment to evolve during the electrolysis in its premelted state between 91 and 124 degrees C. In this temperature range molecules assume rotation around the molecular axes and proton conduction of the Grotthus type takes place possibly along two chains of intermolecular hydrogen bonds running in parallel. Zwitter-ions behave cooperatively as proton donors and acceptors in transferring proton from molecule and molecule via the hydrogen bond networks. This efficient push-pull way of proton transferring seems to account for the fact that no polarization was observed in the dc conduction experiments. The amount of devolved gas appears to be not exactly in accordance with Faraday's law and discussions are made on possible causes for this slight deviation.

    Cerate perovskites of the general formula AM{sub x}Ce{sub 1-x}O{sub 3-{delta}}, where A = Sr or Ba and where M = Gd, Nd, Y, Yb or other rare earth dopant, are known to conduct a protonic current. Such materials may be useful as the electrolyte in a solid oxide fuel cell operating at intermediate temperatures, as an electrochemical hydrogen separation membrane, or as a hydrogen sensor. Conduction mechanisms in these materials were evaluated using dc cyclic voltammetry and mass spectrometry, allowing currents and activation energies for proton, electron, and oxygen ion contributions to the total current to be determined. For SrYb{sub 0.05}Ce{sub 0.95}O{sub 3-{delta}}, one of the best and most environmentally stable compositions, proton conduction followed two different mechanisms: a low temperature process, characterized by an activation energy of 0.42{+-}0.04 eV, and a high temperature process, characterized by an activation energy of 1.38{+-}0.13 eV. It is believed that the low temperature process is dominated by grain boundary conduction while bulk conduction is responsible for the high temperature process. The activation energy for oxygen ion conduction (0.97{+-}0.10 eV) agrees well with other oxygen conductors, while that for electronic conduction, 0.90{+-}0.09 eV, is affected by a temperature-dependent electron carrier concentration. Evaluated by direct measurement of mass flux through a dense ceramic with an applied dc field, oxygen ions were determined to be the majority charge carrier except at the lowest temperatures, followed by electrons and then protons.

    Quantum statistical mechanical method of Bogoliubov-Tyablikov two-time Green's functions (TTGFs) suggested by Zubarev and Tserkovnikov is generalized to include spatially inhomogeneous systems, such as small semiconductor quantum dots, artificial atoms, etc. The developed formalism is applied to derive a fundamental quantum theory of conductivity of spatially inhomogeneous systems in weak external electromagnetic fields. Conservation equations for the charge and current densities are derived and analyzed. Explicit expressions for the linear (in the field potentials) longitudal and transverse quantum conductivity, dielectric and magnetic susceptibilities are also derived in terms of the equilibrium/steady state charge density - charge density and microcurrent-microcurrent retarded TTGFs. The obtained results are used in conjunction with quantum computations of electronic energy spectra of small clusters of In, Ga and As atoms to predict the quantum conductivity of such clusters.

    Effects of self-assembled monolayers (SAMs) of a few different aminothiophenols (ATPs) on growth, morphology, and electrical properties of polyaniline have been studied at gold electrodes employing current sensing atomic force microscopy. The 4-aminothiophenol (4-ATP) SAM showed the best capability of shuttling electrons from the gold electrode to the solution species, and the 4-ATP SAM covered electrode not only showed the best kinetics for the film growth but also produced the film of the highest electrical conductivity. The vertical conductivity of the film ranged from 58 S cm{sup -1} for a film prepared at a bare gold electrode to as high as 148 S cm{sup -1} for a film obtained at the 4-ATP SAM covered electrode. The conductivity was shown to depend on the thickness of the films as well as how they were prepared.

  5. Electrical Conductivity in Textiles

    Science.gov (United States)

    2006-01-01

    Copper is the most widely used electrical conductor. Like most metals, though, it has several drawbacks: it is heavy, expensive, and can break. Fibers that conduct electricity could be the solutions to these problems, and they are of great interest to NASA. Conductive fibers provide lightweight alternatives to heavy copper wiring in a variety of settings, including aerospace, where weight is always a chief concern. This is an area where NASA is always seeking improved materials. The fibers are also more cost-effective than metals. Expenditure is another area where NASA is always looking to make improvements. In the case of electronics that are confined to small spaces and subject to severe stress, copper is prone to breaking and losing connection over time. Flexible conductive fibers eliminate that problem. They are more supple and stronger than brittle copper and, thus, find good use in these and similar situations. While clearly a much-needed material, electrically conductive fibers are not readily available. The cost of new technology development, with all the pitfalls of troubleshooting production and the years of testing, and without the guarantee of an immediate market, is often too much of a financial hazard for companies to risk. NASA, however, saw the need for electrical fibers in its many projects and sought out a high-tech textile company that was already experimenting in this field, Syscom Technology, Inc., of Columbus, Ohio. Syscom was founded in 1993 to provide computer software engineering services and basic materials research in the areas of high-performance polymer fibers and films. In 1999, Syscom decided to focus its business and technical efforts on development of high-strength, high-performance, and electrically conductive polymer fibers. The company developed AmberStrand, an electrically conductive, low-weight, strong-yet-flexible hybrid metal-polymer YARN.

    During his talk to the staff at the beginning of the year, the Director-General mentioned that a new code of conduct was being drawn up. What exactly is it and what is its purpose? Anne-Sylvie Catherin, Head of the Human Resources (HR) Department, talked to us about the whys and wherefores of the project.   Drawing by Georges Boixader from the cartoon strip “The World of Particles” by Brian Southworth. A code of conduct is a general framework laying down the behaviour expected of all members of an organisation's personnel. “CERN is one of the very few international organisations that don’t yet have one", explains Anne-Sylvie Catherin. “We have been thinking about introducing a code of conduct for a long time but lacked the necessary resources until now”. The call for a code of conduct has come from different sources within the Laboratory. “The Equal Opportunities Advisory Panel (read also the "Equal opportuni...

    2006-01-01

    Thermal management has become a ‘hot’ field in recent years due to a need to obtain high performance levels in many devices used in such diverse areas as space science, mainframe and desktop computers, optoelectronics and even Formula One racing cars! Thermal solutions require not just taking care of very high thermal flux, but also ‘hot spots’, where the flux densities can exceed 200 W/cm2. High thermal conductivity materials play an important role in addressing thermal management issues. This volume provides readers a basic understanding of the thermal conduction mechanisms in these materials and discusses how the thermal conductivity may be related to their crystal structures as well as microstructures developed as a result of their processing history. The techniques for accurate measurement of these properties on large as well as small scales have been reviewed. Detailed information on the thermal conductivity of diverse materials including aluminum nitride (AlN), silicon carbide (SiC), diamond, a...

    Disclosed are methods for forming carbon-based fillers as may be utilized in forming highly thermal conductive nanocomposite materials. Formation methods include treatment of an expanded graphite with an alcohol/water mixture followed by further exfoliation of the graphite to form extremely thin carbon nanosheets that are on the order of between about 2 and about 10 nanometers in thickness. Disclosed carbon nanosheets can be functionalized and/or can be incorporated in nanocomposites with extremely high thermal conductivities. Disclosed methods and materials can prove highly valuable in many technological applications including, for instance, in formation of heat management materials for protective clothing and as may be useful in space exploration or in others that require efficient yet light-weight and flexible thermal management solutions.

    Ventura, Guglielmo; Perfetti, Mauro

    After a Sect. 1.1 devoted to electrical conductivity and a section that deals with magnetic and dielectric losses ( 1.2 ), this chapter explores the theory of thermal conduction in solids. The examined categories of solids are: metals Sect. 1.3.2 , Dielectrics Sects. 1.3.3 and 1.3.4 and Nanocomposites Sect. 1.3.5 . In Sect. 1.3.6 the problem of thermal and electrical contact between materials is considered because contact resistance occurring at conductor joints in magnets or other high power applications can lead to undesirable electrical losses. At low temperature, thermal contact is also critical in the mounting of temperature sensors, where bad contacts can lead to erroneous results, in particular when superconductivity phenomena are involved.

    Full Text Available In recent years, conducting polymer (CP nanomaterials have been used in a variety of fields, such as in energy, environmental, and biomedical applications, owing to their outstanding chemical and physical properties compared to conventional metal materials. In particular, nanobiosensors based on CP nanomaterials exhibit excellent performance sensing target molecules. The performance of CP nanobiosensors varies based on their size, shape, conductivity, and morphology, among other characteristics. Therefore, in this review, we provide an overview of the techniques commonly used to fabricate novel CP nanomaterials and their biosensor applications, including aptasensors, field-effect transistor (FET biosensors, human sense mimicking biosensors, and immunoassays. We also discuss prospects for state-of-the-art nanobiosensors using CP nanomaterials by focusing on strategies to overcome the current limitations.

  16. Infrared transparent conductive oxides

    Johnson, Linda F.; Moran, Mark B.

    2001-09-01

    A novel class of complex metal oxides that have potential as transparent conducting oxides (TCOs) for the electromagnetic-interference (EMI) shielding on IR-seeker windows and missile domes has been identified. These complex metal oxides exhibit the rhombohedral (R3m) crystalline structure of naturally occurring delafossite, CuFeO2. The general chemical formula is ABO2 where A is a monovalent metal (Me+1 such as Cu, Ag, Au, Pt or Pd, and B is a trivalent metal (Me3+) such as Al,Ti,Cr,Co,Fe,Ni,Cs,Rh,Ga,Sn,In,Y,La,Pr,Nd,Sm or Eu. By adjusting the oxygen content, the conductivity can be varied over a wide range so that the delafossites behave as insulators, semiconductors or metals. This paper presents results for films of p-type CuxAlyOz and n-type CuxCryOz deposited by reactive magnetron co-sputtering from high-purity-metal targets. Films have been deposited using conventional RF- and DC-power supplies, and a new asymmetric-bipolar-pulsed- DC-power supply. Similar to the high-temperature-copper- oxide superconductors, the presence of Cu-O bonds is critical for the unique properties. Fourier transform infrared (FTIR) and electron spectroscopy for chemical analysis (ESCA) are used to understand the relationship between the optoelectornic properties and the molecular structure of the films. For example, FTIR absorption bands at 1470 and 1395cm-1 are present only in CuxAlyOz films that exhibit enhanced electrical conductivity. When these bands are absent, the CuxAlyOz films have high values of resistivity. In addition to the 1470 and 1395cm-1 bands observed in CuxAlyOz films, another pair of bands at 1040 and 970cm-1 is present in CuxCryOz films.

We review the subject,with an emphasis on the wide-field, imaging surveys, placing them ina broader scientific and historical context. Surveys are now the largestdata generators in astronomy, propelled by the advances in informationand computation technology, and have transformed the ways in whichastronomy is done. This trend is bound to continue, especially with thenew generation of synoptic sky surveys that cover wide areas of the skyrepeatedly and open a new time domain of discovery. We describe thevariety and the general properties of surveys, illustrated by a number ofexamples, the ways in which they may be quantified and compared, andoffer some figures of merit that can be used to compare their scientificdiscovery potential. Surveys enable a very wide range of science, and that isperhaps their key unifying characteristic. As new domains of the observableparameter space open up thanks to the advances in technology, surveys areoften the initial step in their exploration. Some science can be done withthe survey data alone (or a combination of data from different surveys),and some require a targeted follow-up of potentially interesting sourcesselected from surveys. Surveys can be used to generate large, statisticalsamples of objects that can be studied as populations or as tracers of largerstructures to which they belong. They can be also used to discover orgenerate samples of rare or unusual objects and may lead to discoveriesof some previously unknown types. We discuss a general framework ofparameter spaces that can be used for an assessment and comparison ofdifferent surveys and the strategies for their scientific exploration. As we aremoving into the Petascale regime and beyond, an effective processing andscientific exploitation of such large data sets and data streams pose

    1977-01-01

    A program was conducted to develop and test electrically conductive paint coatings for spacecraft. A wide variety of organic and inorganic coatings were formulated using conductive binders, conductive pigments, and similar approaches. Z-93, IITRI's standard specification inorganic thermal control coating, exhibits good electrical properties and is a very space-stable coating system. Several coatings based on a conductive pigment (antimony-doped tin oxide) in silicone and silicate binders offer considerable promise. Paint systems using commercially available conductive polymers also appear to be of interest, but will require substantial development. Evaluations were made based on electrical conductivity, paint physical properties, and the stability of spectral reflectance in space environment testing.

    Thermal conductivity of porous media is considered. The model permits regular power-series expansion of the expression for thermal conductivity as a function of porosity. The coefficients of the expansion depend on two-site correlation function of local thermal conductivities, which can be calculated from the microscopy image of the structure. Thermal conductivities of some model two-dimensional structures as well as a real porous yttria-stabilized zirconia film are calculated and discussed.

    2012-11-01

    We propose a new method that measures skin conductance over clothes to nonintrusively monitor the changes in physiological conditions affecting skin conductance during daily activities. We selected the thigh-to-thigh current path and used an indirectly coupled 5-kHz AC current for the measurement. While varying the skin conductance by the Valsalva maneuver method, the results were compared with the traditional galvanic skin response (GSR) measured directly from the fingers. Skin conductance measured using a 5-kHz current displayed a highly negative correlation with the traditional GSR and the current measured over clothes reflected the rate of change of the conductance of the skin beneath.

    For the first time in decades, conventional wisdom about survey methodology is being challenged on many fronts. The insights gained can not only help psychologists do their research better but also provide useful insights into the basics of social interaction and cognition. This chapter reviews some of the many recent advances in the literature, including the following: New findings challenge a long-standing prejudice against studies with low response rates; innovative techniques for pretesting questionnaires offer opportunities for improving measurement validity; surprising effects of the verbal labels put on rating scale points have been identified, suggesting optimal approaches to scale labeling; respondents interpret questions on the basis of the norms of everyday conversation, so violations of those conventions introduce error; some measurement error thought to have been attributable to social desirability response bias now appears to be due to other factors instead, thus encouraging different approaches to fixing such problems; and a new theory of satisficing in questionnaire responding offers parsimonious explanations for a range of response patterns long recognized by psychologists and survey researchers but previously not well understood.

    The Pregnancy and Birth Survey was started by Fukushima Medical University as part of the Fukushima Health Management Survey in 2011 in order to assess the physical and mental health of mothers and provide parenting support (telephone counseling) for those in need. The present study reviewed the major findings from 4 annual surveys conducted from 2011 to 2014. Overall proportions of preterm deliveries, low birth weight infants, and congenital anomalies in the first year were almost the same as those in national surveillance data. The prevalence of depressive symptoms among the mothers held steady at about 25% over the 4 years. Regarding the content of parenting counseling, the proportion of mothers who voiced concerns about radiation decreased each year. This survey should be continued to provide support to mothers in Fukushima.

    2018-01-01

    To assess the benefits of a new type of hearing aid using cartilage conduction (CC) in patients with severe conduction hearing loss and evaluate its potential for practical use. Consecutive, prospective case series. Forty-one subjects (21 with bilateral aural atresia; 15 with unilateral aural atresia; and 5 others) participated in this study. Fitting and gain adjustments of the CC hearing aids were performed to the ear(s) with conduction hearing loss. The function gains were measured. Evaluation of the measurements of speech performance-intensity functions, speech recognition scores, tolerance of environmental noise, and subject questionnaires were also performed, and judged according to the "Guidelines for the evaluation of hearing aid fitting" established by the Japan Audiological Society. The thresholds were significantly improved by CC hearing aids. The functional gains for CC hearing aids were nearly equivalent to that for their previously used hearing aids. The style of the transducer fixation and the type of aural atresia had no significant influence on the functional gains. Most of the assessment results were judged to be sufficient. Before the trial, bone conduction hearing aids had been used most frequently by bilateral aural atresia subjects. However, after the trial, most subjects continued to use CC hearing aids instead of reverting back to their original device. Overall, 39 subjects continued use of the CC hearing aids. No severe adverse effects were noted in the trial. Cartilage conduction hearing aids could be an additional and beneficial option for severe conduction hearing loss from aural atresia.

  15. Calibration-free electrical conductivity measurements for highly conductive slags

    Energy Technology Data Exchange (ETDEWEB)

    MACDONALD,CHRISTOPHER J.; GAO,HUANG; PAL,UDAY B.; VAN DEN AVYLE,JAMES A.; MELGAARD,DAVID K.

    2000-05-01

    This research involves the measurement of the electrical conductivity (K) for the ESR (electroslag remelting) slag (60 wt.% CaF{sub 2} - 20 wt.% CaO - 20 wt.% Al{sub 2}O{sub 3}) used in the decontamination of radioactive stainless steel. The electrical conductivity is measured with an improved high-accuracy-height-differential technique that requires no calibration. This method consists of making continuous AC impedance measurements over several successive depth increments of the coaxial cylindrical electrodes in the ESR slag. The electrical conductivity is then calculated from the slope of the plot of inverse impedance versus the depth of the electrodes in the slag. The improvements on the existing technique include an increased electrochemical cell geometry and the capability of measuring high precision depth increments and the associated impedances. These improvements allow this technique to be used for measuring the electrical conductivity of highly conductive slags such as the ESR slag. The volatilization rate and the volatile species of the ESR slag measured through thermogravimetric (TG) and mass spectroscopy analysis, respectively, reveal that the ESR slag composition essentially remains the same throughout the electrical conductivity experiments.

    We have investigated thermal conductivity of graphene laminate films deposited on polyethylene terephthalate substrates. Two types of graphene laminate were studied, as deposited and compressed, in order to determine the physical parameters affecting the heat conduction the most. The measurements were performed using the optothermal Raman technique and a set of suspended samples with the graphene laminate thickness from 9 to 44 μm. The thermal conductivity of graphene laminate was found to be in the range from 40 to 90 W/mK at room temperature. It was found unexpectedly that the average size and the alignment of graphene flakes are more important parameters defining the heat conduction than the mass density of the graphene laminate. The thermal conductivity scales up linearly with the average graphene flake size in both uncompressed and compressed laminates. The compressed laminates have higher thermal conductivity for the same average flake size owing to better flake alignment. Coating plastic materials with thin graphene laminate films that have up to 600× higher thermal conductivity than plastics may have important practical implications.

  6. Edge conduction in vacuum glazing

    Vacuum glazing is a form of low-conductance double glazing using in internal vacuum between the two glass sheets to eliminate heat transport by gas conduction and convection. An array of small support pillars separates the sheets; fused solder glass forms the edge seal. Heat transfer through the glazing occurs by radiation across the vacuum gap, conduction through the support pillars, and conduction through the bonded edge seal. Edge conduction is problematic because it affects stresses in the edge region, leading to possible failure of the glazing; in addition, excessive heat transfer because of thermal bridging in the edge region can lower overall window thermal performance and decrease resistance to condensation. Infrared thermography was used to analyze the thermal performance of prototype vacuum glazings, and, for comparison, atmospheric pressure superwindows. Research focused on mitigating the edge effects of vacuum glazings through the use of insulating trim, recessed edges, and framing materials. Experimentally validated finite-element and finite-difference modeling tools were used for thermal analysis of prototype vacuum glazing units and complete windows. Experimental measurements of edge conduction using infrared imaging were found to be in good agreement with finite-element modeling results for a given set of conditions. Finite-element modeling validates an analytic model developed for edge conduction.

    Oren, A Hakan; Ozdamar, Tuğçe

    2013-06-01

    Hydraulic conductivities of compacted zeolites were investigated as a function of compaction water content and zeolite particle size. Initially, the compaction characteristics of zeolites were determined. The compaction test results showed that maximum dry unit weight (γ(dmax)) of fine zeolite was greater than that of granular zeolites. The γ(dmax) of compacted zeolites was between 1.01 and 1.17 Mg m(-3) and optimum water content (w(opt)) was between 38% and 53%. Regardless of zeolite particle size, compacted zeolites had low γ(dmax) and high w(opt) when compared with compacted natural soils. Then, hydraulic conductivity tests were run on compacted zeolites. The hydraulic conductivity values were within the range of 2.0 × 10(-3) cm s(-1) to 1.1 × 10(-7) cm s(-1). Hydraulic conductivity of all compacted zeolites decreased almost 50 times as the water content increased. It is noteworthy that hydraulic conductivity of compacted zeolite was strongly dependent on the zeolite particle size. The hydraulic conductivity decreased almost three orders of magnitude up to 39% fine content; then, it remained almost unchanged beyond 39%. Only one report was found in the literature on the hydraulic conductivity of compacted zeolite, which is in agreement with the findings of this study.

    Full Text Available At present a non-destructive testing of conducting materials becomes very important one in connection with monitoring and control of strategic technical facilities, e.g. nuclear power plants. There are more methods of material testing and evaluation and every of them has its advantages and disadvantages. Recently the electromagnetic methods are in increasing interest. There are many ways of conducting material testing. One of them often used utilises investigation of eddy currents induced in the surface layer by means of a proper coil. The arrangement is very simple and inexpensive but it offers only local information on cracks and other inhomogeneities in the thin surface layer. On the other hand there exist a method based on an electromagnetic – acoustic transducer (EMAT, which is able to generate and detect acoustic wave in a conducting body in a contact-less way. The present paper deals with a survey of EMATs for investigation of thin metalliclayers by means of Lamb waves. The new design of generation coil is presented.

    Robotic telescopes are revolutionizing the way astronomers collect their dataand conduct sky surveys. This chapter begins with a discussion of principles thatguide the process of designing, constructing, and operating telescopes andobservatories that offer a varying degree of automation, from instruments remotelycontrolled by observers to fully autonomous systems requiring no humansupervision during their normal operations. Emphasis is placed on designtrade-offs involved in building end-to-end systems intended for a wide range ofscience applications. The second part of the chapter contains descriptions ofseveral projects and instruments, both existing and currently under development.It is an attempt to provide a representative selection of actual systems thatillustrates state of the art in technology, as well as important ideas and milestonesin the development of the field. The list of presented instruments spans the fullrange in size starting from small all-sky monitors, through midrange robotic andsurvey telescopes, and finishing with large robotic instruments and surveys.Explosive growth of telescope networking is enabling entirely new modesof interaction between the survey and follow-up observing. Increasingimportance of standardized communication protocols and software is stressed.These developments are driven by the fusion of robotic telescope hardware,massive storage and databases, real-time knowledge extraction, and datacross-correlation on a global scale. The chapter concludes with examplesof major science results enabled by these new technologies and futureprospects.

    High-risk behaviours -- smoking, drug use, alcohol use and etc. are the main risk factors of non-communicable diseases and main reasons of morbidity and mortality in many countries of the world. We conducted the "Youth Health Behaviour Survey" among the students in Tbilisi, Mtskheta and Dusheti. The survey included questioning of students (14-17 years old) by modified questionnaire. There were questioned 300 students, 100 in each region. Mtskheta is very close to Tbilisi, it's a peri-urban area; Dusheti is quite far rural area. The survey results show that teenagers both in central and peripheral areas are becoming familiar with alcohol in early ages and using alcohol is several times higher in Tbilisi. In Tbilisi as in Mtskheta and Dusheti students use wine and spirits with same frequency. Smoking is a bit high in Tbilisi and Mtskheta; regular smoking starts at age 13-14, boys are smoking more than girls. Drug use wasn't identified. Sexual intercourse had almost half of boys from Tbilisi and about one third of boys in Mtskheta and Dusheti. Safe sex methods more frequently are used in Tbilisi. Propaganda of healthy life style is essential in supporting healthy youth development. It's very important to set different interventions in different regions of Georgia, to adapt materials to real situation.

  11. Hydrological Aspects of Electromagnetic Surveys

    Baden G. Williams

    2014-01-01

    Full Text Available Interpreting Electromagnetic (EM surveys - Electromagnetic induction techniques have now largely replaced previous descriptive, and largely subjective, techniques used for soil salinity surveys. The question then is a matter of how to interpret the EM data. A very clear linkage exists between Apparent Electrical Conductivity (ECa and the total soluble salts in the upper soil profile. This, in turn, can be interpreted as reflecting the degree of vertical/ lateral leaching of soluble salts, or of salt accumulation in the profile. Topography, depth to groundwater and groundwater salinity also appear to affect ECa, although they are not suited to rapid survey techniques and do not necessarily have a direct relationship with either the total salt content of the upper soil profile or the ECa values. The interpretation of isoconductivity maps in terms of the degree of leaching of the soil profile from point to point provides an added hydrological management perspective to EM soil salinity surveys.

    The use of cathodic protection to prevent the corrosion of reinforcing steel in concrete structures has been well established. Application of a durable, skid-resistant electrically conductive polymer concrete overlay would advance the use of cathodic protection for the highway industry. Laboratory studies indicate that electrically conductive polymer concrete overlays using conductive fillers, such as calcined coke breeze, in conjunction with polyester or vinyl ester resins have resistivities of 1 to 10 ohm-cm. Both multiple-layer and premixed mortar-type overlays were made. Shear bond strengths of the conductive overlays to concrete substrates vary from 600 to 1300 psi, with the premixed overlays having bond strengths 50 to 100% higher than the multiple-layer overlays.

    A thermal conduction switch includes a thermally-conductive first member having a first thermal contacting structure for securing the first member as a stationary member to a thermally regulated body or a body requiring thermal regulation. A movable thermally-conductive second member has a second thermal contacting surface. A thermally conductive coupler is interposed between the first member and the second member for thermally coupling the first member to the second member. At least one control spring is coupled between the first member and the second member. The control spring includes a NiTiFe comprising shape memory (SM) material that provides a phase change temperature <273 K, a transformation range <40 K, and a hysteresis of <10 K. A bias spring is between the first member and the second member. At the phase change the switch provides a distance change (displacement) between first and second member by at least 1 mm, such as 2 to 4 mm.

  18. Database for hydraulically conductive fractures

    Posiva flow logging (PFL) with a 0.5 m test interval and made in 10 cm steps can be used for the determination of the depth of hydraulically conductive fractures. Together with drillhole wall images and fracture data from core logging, PFL provides possibilities to detect individual conductive fractures. In this report, the results of PFL are combined with fracture data on drillholes OL-KR1 - OL-KR40, OL-KR15B - KR20B, OL-KR22B - KR23B, OL-KR25B, OL-KR27B, OL-KR29B, OL-KR31B, OLKR33B, OL-KR37B and OL-KR39B - KR40B and pilot holes OL-PH1 and ONK-PH2 - ONK-PH7. The conductive fractures were first recognised from PFL data and digital drillhole images and then the fractures from the core logging that correspond to the ones picked from the digital drillhole images were identified. The conductive fractures were primarily recognised in the images based on the openness of fractures or a visible flow in the image. In most of the cases, no tails of flow were seen in the image. In these cases the conductive fractures were recognised in the image based on the openness of fractures and a matching depth. On the basis of the results hydraulically conductive fractures/zones could in most cases be distinguished in the drillhole wall images. An important phase in the work is the calibration of the depth of the image and flow logging with the sample length. Hydraulic conductivity is clearly higher in the upper part of the bedrock in the depth range 0-150 m below sea level than deeper in the bedrock. The frequency of hydraulically conductive fractures (T > 10-10-10-9 m2/s) in depth range 0-150 m varies between 0.06 and 0.78 fractures/metre of sample length. Deeper in the rock conductive fractures are less frequent, but often occur in groups of a few fractures. About 10% of the conductive fractures are within HZ-structures and 6% within BFZ-structures. 3% of the conductive fractures are within HZ- and BFZ-structures. (orig.)

    1996-11-10

    Coal samples in the form of randomly oriented aggregates were obtained from the Pennsylvania State University Coal Bank for the purpose of thermal conductivity measurements. Samples represented 55 locations from throughout the United States and included 6 lignites, 10 subbituminous coals, 36 bituminous coals, and 3 anthracite samples. Matrix thermal conductivities measured at 22{degree}C in the laboratory ranged from 0.22 to 0.55 W/m degree K, with an arithmetic mean of 0.33 W/m degrees K and a standard deviation of 0.07 W/m degrees K. The thermal conductivity of lignites, subbituminous, and bituminous coals is controlled by composition and can be predicted by a three-component (Moisture, ash, and carbon + volatiles) geometric mean model with a rns residual of 6.1%. The thermal conductivity of bituminous and anthracite samples was found to be positively correlated with matrix density. With the exception of three anthracite samples, rank was not correlated with thermal conductivity nor was the ratio of carbon to volatiles. The relatively high thermal conductivity of three anthracite samples (mean of 0.49 W/m degrees K) may have been related to graphitization.

    This study investigates the comorbidity and longitudinal associations between self-reported conduct disorder and subclinical bulimia in a community-based sample of Finnish adolescents in a 2-year prospective follow-up study. There are 2070 adolescents who participated in the survey as ninth graders (mean age 15.5) and followed-up 2 years later. The Youth Self-Report Externalizing scale was used to measure conduct disorder and DSM-IV-based questionnaire to measure bulimia. Co-occurrence of female conduct disorder and subclinical bulimia was found at ages 15 and 17. Subclinical bulimia among girls at age 15 was a risk factor for conduct disorder at age 17, but conduct disorder at age 15 was not predictive of subclinical bulimia at age 17. The pathway from bulimia to conduct disorder may be suggestive of an association with future borderline personality disorder among girls.

    Full Text Available Conducting polymer 3D microelectrodes have been fabricated for possible future neurological applications. A combination of micro-fabrication techniques and chemical polymerization methods has been used to create pillar electrodes in polyaniline and polypyrrole. The thin polymer films obtained showed uniformity and good adhesion to both horizontal and vertical surfaces. Electrodes in combination with metal/conducting polymer materials have been characterized by cyclic voltammetry and the presence of the conducting polymer film has shown to increase the electrochemical activity when compared with electrodes coated with only metal. An electrochemical characterization of gold/polypyrrole electrodes showed exceptional electrochemical behavior and activity. PC12 cells were finally cultured on the investigated materials as a preliminary biocompatibility assessment. These results show that the described electrodes are possibly suitable for future in-vitro neurological measurements.

Art. 32 of the Italian Constitution, relating to the ''right to health'' is examined, paying particular attention to certain parts, and is related to Art. 35 of the European Union Charter of Fundamental Rights. In considering Art. 43 of the Penal Code, which addresses the psychological element of criminal acts, reference is made to the Medical Code of Conduct and to the Hippocratic Oath. The considerations made point up the importance of a relationship of trust and esteem between doctor and patient in clinical practice, and that this approach must be cultivated starting from the first year of university studies.

    Petersen, Rasmus Rosenlund; König, Jakob; Yue, Yuanzheng

    Due to the increased focus on energy savings and waste recycling foam glass materials have gained increased attention. The production process of foam glass is a potential low-cost recycle option for challenging waste, e.g. CRT glass and industrial waste (fly ash and slags). Foam glass is used...... as thermal insulating material in building and chemical industry. The large volume of gas (porosity 90 – 95%) is the main reason of the low thermal conductivity of the foam glass. If gases with lower thermal conductivity compared to air are entrapped in the glass melt, the derived foam glass will contain...... only closed pores and its overall thermal conductivity will be much lower than that of the foam glass with open pores. In this work we have prepared foam glass using different types of recycled glasses and different kinds of foaming agents. This enabled the formation of foam glasses having gas cells...

    For many years the attempts to create conductive channels of big length were taken in order to study the upper atmosphere and to settle special tasks, related to energy transmission. There upon the program of creation of "Impulsar" represents a great interest, as this program in a combination with high-voltage high repetition rate electrical source can be useful to solve the above mentioned problems (N. Tesla ideas for the days of high power lasers). The principle of conductive channel production can be shortly described as follows. The "Impulsar"—laser jet engine vehicle—propulsion take place under the influence of powerful high repetition rate pulse-periodic laser radiation. In the experiments the CO2—laser and solid state Nd:YAG laser systems had been used. Active impulse appears thanks to air breakdown (30 km), placed in the vicinity of the focusing mirror-acceptor of the breakdown waves. With each pulse of powerful laser the device rises up, leaving a bright and dense trace of products with high degree of ionization and metallization by conductive nano-particles due to ablation. Conductive dust plasma properties investigation in our experiments was produced by two very effective approaches: high power laser controlled ablation and by explosion of wire. Experimental and theoretical results of conductive canal modeling will be presented. The estimations show that with already experimentally demonstrated figures of specific thrust impulse the lower layers of the Ionosphere can be reached in several ten seconds that is enough to keep the high level of channel conductivity and stability with the help of high repetition rate high voltage generator. Some possible applications for new technology are highlighted.

    Polyelectrolytes have many important functions in both living organisms and man-made applications. One key property of polyelectrolytes is the ionic conductivity due to their porous networks that allow the transport of water and small molecular solutes. Among polyelectrolytes, zwitterionic polymers have attracted huge attention for applications that involve ion transport in a polyelectrolyte matrix; however, it is still unclear how the functional groups of zwitterionic polymer side chains affect their ion transport and swelling properties. In this study, zwitterionic poly(carboxybetaine acrylamide), poly(2-methacryloyloxyethyl phosphorylcholine), and poly(sulfobetaine methacrylate) hydrogels were synthesized and their ionic conductivity was studied and compared to cationic, anionic, and nonionic hydrogels. The change of the ionic conductivity of zwitterionic and nonionic hydrogels in different saline solutions was investigated in detail. Zwitterionic hydrogels showed much higher ionic conductivity than that of the widely used nonionic poly(ethylene glycol) methyl ether methacrylate hydrogel in all tested solutions. For both cationic and anionic hydrogels, the presence of mobile counterions led to high ionic conductivity in low salt solutions; however, the ionic conductivity of zwitterionic hydrogels surpassed that of cationic and ionic hydrogels in high salt solutions. Cationic and anionic hydrogels showed much higher water content than that of zwitterionic hydrogels in deionized water; however, the cationic hydrogels shrank significantly with increasing saline concentration. This work provides insight into the effects of polyelectrolyte side chains on ion transport. This can guide us in choosing better polyelectrolytes for a broad spectrum of applications, including bioelectronics, neural implants, battery, and so on.

    Full Text Available The article focuses on the application of the factorial survey design to social- psychological studies. The factorial survey is an experimental technique that allows testing hypotheses about causal relations. The key advantages of factorial survey are (1 higher external validity compared to classical laboratory experiments, (2 lower susceptibility to social desirability effects compared to classical survey approach, and (3 its ability to detect implicit determinants of social perception. Nevertheless, facto- rial survey design is rarely used in psychology. This work gives an introduction to the factorial survey design, describes its benefits and areas of application. Moreover, it gives practical guidelines on how to plan, conduct, and analyze the results of a factorial survey study, accompanied by examples from our own research.

    The use of electrically conductive composite structures for electrostatic dissipation, electromagnetic interference shielding, and ground return planes could save between 30 and 90 percent of the mass of the structure, in comparison to aluminum. One strategy that has been shown to make conducting composites effectively uses intercalated graphite fiber as the reinforcement. Intercalation--the insertion of guest atoms or molecules between the graphene planes--can lower the electrical resistivity of graphite fibers by as much as a factor of 10, without sacrificing mechanical or thermal properties.

Isothermal annealing of the vanadate glass for several ten minutes at a given temperature, higher than glass transition temperature or crystallization temperature, caused an increase in σ. Substitution of CuI (3d10, ZnII (3d10 and CuII (3d9 for FeIII (3d5 was investigated to elucidate the effect of electron configuration on the conductivity (σ. A marked decrease in the activation energy of conduction (Ea was also observed after the annealing. Values of Ea were correlated to the energy gap between the donor level and the conduction band (CB in the n-type semiconductor model. Isothermal annealing of ZnII-substituted vanadate glass (20 BaO ∙ 5 ZnO ∙ 5 Fe2O3 ∙ 70 V2O5 at 450 °C for 30 min showed an increase in σ from 2.5 × 10–6 to 2.1 × 10–1 S cm–1, which was one order of magnitude larger than that of non-substituted vanadate glass (3.4 × 10–2 S cm–1. Under the same annealing condition, σ’s of 2.0 × 10–1 and 3.2 × 10–1 S cm–1 were observed for 20 BaO ∙ 5 Cu2O ∙ 5 Fe2O3 ∙ 70 V2O5 and 20 BaO ∙ 5 CuO ∙ 5 Fe2O3 ∙ 70 V2O5 glasses, respectively.

    1976-10-01

    Thermal conductivity measurements have been used to study the temperature dependence of the various scattering mechanisms present in single crystals of NbSe in a temperature range from 1 to 10/sup 0/K. Phonons are found to contribute a substantial fraction of the conduction in this temperature range and, in general, the results agree well with standard theoretical models for three-dimensional metals. The presence of van der Waals boundaries beween the layers introduces no significant boundary scattering for phonons. In addition to the usual electron and point defect scattering terms which are present in the phonon conductivity, a term which has a linear temperature dependence was found. This linear term may be caused by stacking fault scattering centers. A linear field dependence of the electrical magnetoresistance is reported and it is suggested this term may arise from magnetic breakdown at energy gaps in the Fermi surface induced by charge-density waves as suggested by Overhauser. It is noted that the ratio of the superconducting to normal state thermal conductivity is consistent with a BCS-like superconducting energy gap.

    Despite extensive studies on thermal transport in thin silicon films, there has been little work studying the thermal conductivity of single-crystal rectangular, cross-sectional nanobeams that are commonly used in many applications such as nanoelectronics (FinFETs), nano-electromechanical systems, and nanophotonics. Here, we report experimental data on the thermal conductivity of silicon nanobeams of a thickness of ˜78 nm and widths of ˜65 nm, 170 nm, 270 nm, 470 nm, and 970 nm. The experimental data agree well (within ˜9%) with the predictions of a thermal conductivity model that uses a combination of bulk mean free paths obtained from ab initio calculations and a suppression function derived from the kinetic theory. This work quantifies the impact of nanobeam aspect ratios on thermal transport and establishes a criterion to differentiate between thin films and beams in studying thermal transport. The thermal conductivity of a 78 nm × 65 nm nanobeam is ˜32 W m-1 K-1, which is roughly a factor of two smaller than that of a 78 nm thick film.

    A major problem challenging specialists in present-day materials sciences is the development of compact, cheap to fabricate heat sinks for electronic devices, primarily for computer processors, semiconductor lasers, high-power microchips, and electronics components. The materials currently used for heat sinks of such devices are aluminum and copper, with thermal conductivities of about 250 W/(m·K) and 400 W/(m·K), respectively. Significantly, the thermal expansion coefficient of metals differs markedly from those of the materials employed in semiconductor electronics (mostly silicon); one should add here the low electrical resistivity metals possess. By contrast, natural single-crystal diamond is known to feature the highest thermal conductivity of all the bulk materials studied thus far, as high as 2,200 W/(m·K). Needless to say, it cannot be applied in heat removal technology because of high cost. Recently, SiC- and AlN-based ceramics have started enjoying wide use as heat sink materials; the thermal conductivity of such composites, however, is inferior to that of metals by nearly a factor two. This prompts a challenging scientific problem to develop diamond-based composites with thermal characteristics superior to those of aluminum and copper, adjustable thermal expansion coefficient, low electrical conductivity and a moderate cost, below that of the natural single-crystal diamond. The present review addresses this problem and appraises the results reached by now in studying the possibility of developing composites in diamond-containing systems with a view of obtaining materials with a high thermal conductivity.

  13. Electrically Conductive Anodized Aluminum Surfaces

    Science.gov (United States)

    Nguyen, Trung Hung

    2006-01-01

    Anodized aluminum components can be treated to make them sufficiently electrically conductive to suppress discharges of static electricity. The treatment was conceived as a means of preventing static electric discharges on exterior satin-anodized aluminum (SAA) surfaces of spacecraft without adversely affecting the thermal-control/optical properties of the SAA and without need to apply electrically conductive paints, which eventually peel off in the harsh environment of outer space. The treatment can also be used to impart electrical conductivity to anodized housings of computers, medical electronic instruments, telephoneexchange equipment, and other terrestrial electronic equipment vulnerable to electrostatic discharge. The electrical resistivity of a typical anodized aluminum surface layer lies between 10(exp 11) and 10(exp 13) Omega-cm. To suppress electrostatic discharge, it is necessary to reduce the electrical resistivity significantly - preferably to conductive metal oxide nanocomposite. Filling the pores with the nanocomposite reduces the transverse electrical resistivity and, in the original intended outer-space application, the exterior covering portion of the nanocomposite would afford the requisite electrical contact with the outer-space plasma. The electrical resistivity of the nanocomposite can be tailored to a value between 10(exp 7) and 10(exp 12) Omega-cm. Unlike electrically conductive paint, the nanocomposite becomes an integral part of the anodized aluminum substrate, without need for adhesive bonding material and without risk of subsequent peeling. The electrodeposition process is compatible with commercial anodizing production lines. At present, the electronics industry uses expensive, exotic, electrostaticdischarge- suppressing finishes: examples include silver impregnated anodized, black electroless nickel, black chrome, and black copper. In comparison with these competing finishes, the present nanocomposite finishes are expected to cost 50

  17. Comparison of Satellite Surveying to Traditional Surveying Methods for the Resources Industry

    Osborne, B. P.; Osborne, V. J.; Kruger, M. L.

    Modern ground-based survey methods involve detailed survey, which provides three-space co-ordinates for surveyed points, to a high level of accuracy. The instruments are operated by surveyors, who process the raw results to create survey location maps for the subject of the survey. Such surveys are conducted for a location or region and referenced to the earth global co- ordinate system with global positioning system (GPS) positioning. Due to this referencing the survey is only as accurate as the GPS reference system. Satellite survey remote sensing utilise satellite imagery which have been processed using commercial geographic information system software. Three-space co-ordinate maps are generated, with an accuracy determined by the datum position accuracy and optical resolution of the satellite platform.This paper presents a case study, which compares topographic surveying undertaken by traditional survey methods with satellite surveying, for the same location. The purpose of this study is to assess the viability of satellite remote sensing for surveying in the resources industry. The case study involves a topographic survey of a dune field for a prospective mining project area in Pakistan. This site has been surveyed using modern surveying techniques and the results are compared to a satellite survey performed on the same area.Analysis of the results from traditional survey and from the satellite survey involved a comparison of the derived spatial co- ordinates from each method. In addition, comparisons have been made of costs and turnaround time for both methods.The results of this application of remote sensing is of particular interest for survey in areas with remote and extreme environments, weather extremes, political unrest, poor travel links, which are commonly associated with mining projects. Such areas frequently suffer language barriers, poor onsite technical support and resources.

    Heat management with common textiles such as nylon and spandex is hindered by the poor thermal conductivity from the skin surface to cooling surfaces. This innovation showed marked improvement in thermal conductivity of the individual fibers and tubing, as well as components assembled from them. The problem is centered on improving the heat removal of the liquid-cooled ventilation garments (LCVGs) used by astronauts. The current design uses an extensive network of water-cooling tubes that introduces bulkiness and discomfort, and increases fatigue. Range of motion and ease of movement are affected as well. The current technology is the same as developed during the Apollo program of the 1960s. Tubing material is hand-threaded through a spandex/nylon mesh layer, in a series of loops throughout the torso and limbs such that there is close, form-fitting contact with the user. Usually, there is a nylon liner layer to improve comfort. Circulating water is chilled by an external heat exchanger (sublimator). The purpose of this innovation is to produce new LCVG components with improved thermal conductivity. This was addressed using nanocomposite engineering incorporating high-thermalconductivity nanoscale fillers in the fabric and tubing components. Specifically, carbon nanotubes were added using normal processing methods such as thermoplastic melt mixing (compounding twin screw extruder) and downstream processing (fiber spinning, tubing extrusion). Fibers were produced as yarns and woven into fabric cloths. The application of isotropic nanofillers can be modeled using a modified Nielsen Model for conductive fillers in a matrix based on Einstein s viscosity model. This is a drop-in technology with no additional equipment needed. The loading is limited by the ability to maintain adequate dispersion. Undispersed materials will plug filtering screens in processing equipment. Generally, the viscosity increases were acceptable, and allowed the filled polymers to still be

    Nurse scientists are increasingly recognizing the necessity of conducting research with community groups to effectively address complex health problems and successfully translate scientific advancements into the community. Although several barriers to conducting research with community groups exist, community-based participatory research (CBPR) has the potential to mitigate these barriers. CBPR has been employed in programs of research that respond in culturally sensitive ways to identify community needs and thereby address current health disparities. This article presents case studies that demonstrate how CBPR principles guided the development of (a) a healthy body weight program for urban, underserved African American women; (b) a reproductive health educational intervention for urban, low-income, underserved, ethnically diverse women; and (c) a pilot anxiety/depression intervention for urban, low-income, underserved, ethnically diverse women. These case studies illustrate the potential of CBPR as an orientation to research that can be employed effectively in non-research-intensive academic environments. © The Author(s) 2015.

    An electrically conductive flat black paint has been developed for use on the Galileo spacecraft which will orbit Jupiter in the late 1980s. The paint, designed for equipment operating in high-energy radiation fields, has multipurpose functions. Its electrical conductivity keeps differential charging of the spacecraft external surfaces and equipment to a minimum, preventing the buildup of electrostatic fields and arcing. Its flat black aspect minimizes the effects of stray light and unwanted reflectances, when used in optical instruments and on sunshades. Its blackness is suitable, also, for thermal control, when the paint is put on spacecraft surfaces. The paint has good adherence properties, as measured by tape tests, when applied properly to a surface. The electrically conductive paint which was developed has the following characteristics: an electrical resistivity of 5 x 10 to the 7th ohms per square; a visual light total reflectance of approximately 5 percent; an infrared reflectance of 0.13 measured over a spectrum from 10 to the (-5.5) power to 0.001 meter; a solar absorptivity, alpha-s, of 0.93, and a thermal emissivity, epsilon, of 0.87, resulting in an alpha-s/epsilon of 1.07. The formula for making the paint and the process for applying it are described.

    Single-cell solid oxide fuel cells were constructed using strontium cerate as the electrolyte and their performance tested. Like certain zirconates, hafnates, and tantalates, the cerate perovskites are among a class of solid electrolytes that conduct protons at elevated temperatures. Depending on the temperature and chemical environment, these ceramics also support electronic and oxygen ion currents. A maximum power output of {approx}100 mW per cm{sup 2} electrolyte surface area was obtained at 900{degrees}C using 4% hydrogen as the fuel and air as the oxidant. A series of rare earth/ceria/zirconia were prepared and their electrical properties characterized. Rare earth dopants included ytterbia, yttria, terbia, and europia. Ionic conductivities were highest for rare earth/ceria and rare earth zirconia compositions; a minimum in ionic conductivity for all series were found for equimolar mixtures of ceria and zirconia.

  6. National narcolepsy survey

    LENUS (Irish Health Repository)

    Doherty, L.

    2010-04-01

    Narcolepsy is characterised by excessive daytime sleepiness and cataplexy and has a prevalence of 25 per 100,000. We suspect this is higher than presently seen in the Republic of Ireland. We aimed to calculate the Irish prevalence of Narcolepsy and to examine current management practices. We conducted an online survey of respiratory physicians, neurologists, paediatric neurologists, and psychiatrists with an interest in sleep disorders (73% response rate). Of this group, a total of 16 physicians managed 180 patients prior to January 2009. A clinical diagnosis alone was reached in 67 (41%) patients, the remainder by polysomnography or multiple sleep latency testing. No patients were diagnosed by cerebro-spinal fluid analysis of hypocretin levels. While 70 (42%) patients received modafanil, only 7 (4%) were treated with sodium oxybate. Even allowing for missing data it is apparent that Narcolepsy is hugely under-diagnosed in Ireland, however, current practises adhere with new international guidelines.

  8. CONDUCTIVE CHANNEL FOR ENERGY TRANSMISSION

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Laser spark obtained by using a conical optics is much more appropriate to form conducting channels in atmosphere. Only two types of lasers are actively considered to be used in forming high-conductivity channels in atmosphere, controlled by laser spark: pulsed sub-microsecond gas and chemical lasers (CO2, DF and short pulse solid-state and UV lasers. Main advantage of short pulse lasers is their ability in forming of super long ionized channels with a characteristic diameter of ~100  µ  in atmosphere along the  beam propagation direction. At estimated electron densities below  10 ⋅ 16 cm–3 in these filaments and laser wavelengths in the range of 0,5–1,0 mm, the plasma barely absorbs laser radiation.  In this case, the length of the track composed of many filaments is determined by the laser intensity and may reach many kilometers at a femtosecond pulse energy of ~100 mJ. However, these lasers could not be used to form high-conductivity long channels in atmosphere. The ohmic resistance of this type a conducting channels turned out to be very high, and the gas in the channels could not be strongly heated (< 1 J. An electric breakdown controlled by radiation of femtosecond solid-state laser was implemented in only at a length of 3 m with a voltage of 2 MV across the discharge gap (670 kV/m.Not so long ago scientific group from P. N. Lebedev has improved that result, the discharge gap – 1 m had been broken under KrF laser irradiation when switching high-voltage (up to 390 kV/m electric discharge by 100-ns UV pulses. Our previous result  –  16 m long conducting channel controlled by a  laser spark at the voltage  –  3 MV  – was obtained more than 20 years ago in Russia and Japan by using pulsed CO2  laser with energy  –  0,5 kJ. An average electric field strength  was < 190 kV/m. It is still too much for efficient applications.

  18. Multifractal conductance fluctuations in graphene

    Science.gov (United States)

    Bid, Aveek; Rafsanjani Amin, Kazi; Pal, Nairita; Sankar Ray, Samriddhi; Pandit, Rahul

    A multifractal (MF) system is characterized by scaling laws involving an infinite number of exponents. In condensed-matter systems, signatures of multifractality have typically been found in the structure of the critical wave functions at localization delocalization (LD) transitions. We report here the first experimental observation of MF statistics in the transport coefficients of a quantum-condensed matter system. We unearth this through a careful investigation of the magneto-conductance fluctuations in ultra-high mobility single layer graphene at ultra-low temperatures. We obtain the MF spectra over a wide range of temperature and doping levels and show that the multifractality decreases as the temperature increases or as the doping moves the system away from the Dirac point. We show that the fractal exponents are a universal function of the phase coherence length of the carriers. We propose that a probable origin of the MF magneto-conductance fluctuations observed by us is an incipient Anderson LD transition in graphene near the charge neutrality point - a phenomenon predicted but never observed in single layer graphene. We also explore alternate possibilities of the origin of the multifractality namely relativistic quantum scars.

  19. Conduction-coupled Tesla transformer.

    Science.gov (United States)

    Reed, J L

    2015-03-01

    A proof-of-principle Tesla transformer circuit is introduced. The new transformer exhibits the high voltage-high power output signal of shock-excited transformers. The circuit, with specification of proper circuit element values, is capable of obtaining extreme oscillatory voltages. The primary and secondary portions of the circuit communicate solely by conduction. The destructive arcing between the primary and secondary inductors in electromagnetically coupled transformers is ubiquitous. Flashover is eliminated in the new transformer as the high-voltage inductors do not interpenetrate and so do not possess an annular volume of electric field. The inductors are remote from one another. The high voltage secondary inductor is isolated in space, except for a base feed conductor, and obtains earth by its self-capacitance to the surroundings. Governing equations, for the ideal case of no damping, are developed from first principles. Experimental, theoretical, and circuit simulator data are presented for the new transformer. Commercial high-temperature superconductors are discussed as a means to eliminate the counter-intuitive damping due to small primary inductances in both the electromagnetic-coupled and new conduction-coupled transformers.

    Aldissi, Mahmoud

    1989-01-01

    Polymers which are soluble in water and are electrically conductive. The monomer repeat unit is a thiophene or pyrrole molecule having an alkyl group substituted for the hydrogen atom located in the beta position of the thiophene or pyrrole ring and having a surfactant molecule at the end of the alkyl chain. Polymers of this class having 8 or more carbon atoms in the alkyl chain exhibit liquid crystalline behavior, resulting in high electrical anisotropy. The monomer-to-monomer bonds are located between the carbon atoms which are adjacent to the sulfur or nitrogen atoms. The number of carbon atoms in the alkyl group may vary from 1 to 20 carbon atoms. The surfactant molecule consists of a sulfonate group, or a sulfate group, or a carboxylate group, and hydrogen or an alkali metal. Negative ions from a supporting electrolyte which may be used in the electrochemical synthesis of a polymer may be incorporated into the polymer during the synthesis and serve as a dopant to increase the conductivity.

    This qualitative study assessed how clinicians prepared and used interpreters during psychotherapeutic sessions and investigated the strategies they used to manage the dynamics of this process. Ten therapists were interviewed at the Victorian Foundation for the Survivors of Torture (VFST). A semi-structured interview format was used. Thematic analysis was conducted on transcripts of recorded interviews to identify key themes. Factors affecting the provision of psychotherapy with interpreters agreed with general guidelines for working with interpreters but there were exceptions. The possible roles of the interpreter as a cultural consultant, community advocate and co-therapist were explored. Specific troubleshooting strategies were identified for improving empathy, redefining roles, and adjusting interactions with interpreters. Working with interpreters in psychotherapy is a complex process. These findings may benefit clinicians providing psychotherapy to patients using interpreters. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    The objectives of this program are to provide design criteria, techniques, materials, and test methods to ensure control of absolute and differential charging of spacecraft surfaces. The control of absolute and differential charging of spacecraft cannot be effected without the development of new and improved or modified materials or techniques that will provide electrical continuity over the surface of the spacecraft. The materials' photoemission, secondary emission, thermooptical, physical, and electrical properties in the space vacuum environment both in the presence and absence of electrical stress and ultraviolet, electron, and particulate radiation, are important to the achievement of charge control. The materials must be stable or have predictable response to exposure to the space environment for long periods of time. The materials of interest include conductive polymers, paints, transparent films and coatings as well as fabric coating interweaves.

  5. Aqueous supercapacitors on conductive cotton

    KAUST Repository

    Pasta, Mauro

    2010-06-01

    Wearable electronics offer the combined advantages of both electronics and fabrics. In this article, we report the fabrication of wearable supercapacitors using cotton fabric as an essential component. Carbon nanotubes are conformally coated onto the cotton fibers, leading to a highly electrically conductive interconnecting network. The porous carbon nanotube coating functions as both active material and current collector in the supercapacitor. Aqueous lithium sulfate is used as the electrolyte in the devices, because it presents no safety concerns for human use. The supercapacitor shows high specific capacitance (~70-80 F·g-1 at 0.1 A·g-1) and cycling stability (negligible decay after 35,000 cycles). The extremely simple design and fabrication process make it applicable for providing power in practical electronic devices. © 2010 Tsinghua University Press and Springer-Verlag Berlin Heidelberg.

  7. Thermal conductivity of molten metals

    Energy Technology Data Exchange (ETDEWEB)

    Peralta-Martinez, Maria Vita

    2000-02-01

    A new instrument for the measurement of the thermal conductivity of molten metals has been designed, built and commissioned. The apparatus is based on the transient hot-wire technique and it is intended for operation over a wide range of temperatures, from ambient up to 1200 K, with an accuracy approaching 2%. In its present form the instrument operates up to 750 K. The construction of the apparatus involved four different stages, first, the design and construction of the sensor and second, the construction of an electronic system for the measurement and storage of data. The third stage was the design and instrumentation of the high temperature furnace for the melting and temperature control of the sample, and finally, an algorithm was developed for the extraction of the thermal conductivity from the raw measurement data. The sensor consists of a cylindrical platinum-wire symmetrically sandwiched between two rectangular plane sheets of alumina. The rectangular sensor is immersed in the molten metal of interest and a voltage step is applied to the ends of the platinum wire to induce heat dissipation and a consequent temperature rise which, is in part, determined by the thermal conductivity of the molten metal. The process is described by a set of partial differential equations and appropriate boundary conditions rather than an approximate analytical solution. An electronic bridge configuration was designed and constructed to perform the measurement of the resistance change of the platinum wire in the time range 20 {mu}s to 1 s. The resistance change is converted to temperature change by a suitable calibration. From these temperature measurements as a function of time the thermal conductivity of the molten metals has been deduced using the Finite Element Method for the solution of the working equations. This work has achieved its objective of improving the accuracy of the measurement of the thermal conductivity of molten metals from {+-}20% to {+-}2%. Measurements

    The survey provided by the College of American Pathologists (CAP) is chosen as one of the proficiency testing programs in Japan, and, recently, the numbers of participating facilities have increased. CAP provides 754 programs, and more than 1,000 tests were provided in 2014. Materials are translated as the "CAP global inter-laboratory comparison program" under the instruction of the Japanese Society of Laboratory Medicine (JSLM) selected from CAP surveys in Japan, and 68 programs and 261 items are provided. The total number of participating facilities was 174. CAP itself and the other services CAP provides are not well-known, while recognition of "the CAP survey as the proficiency test" has increased. The question "What is CAP and the CAP survey" was analyzed as a result of the questionnaire surveys conducted in 2014, and the advantage of the CAP survey and how to utilize it were considered. A questionnaire survey was conducted about the CAP survey for Japanese participants in 2014. Fifty-three questions were asked about their satisfaction level, intended use, and improvement. Eighty replies were analyzed. As a result, most CAP survey participants are satisfied. They intend to mainly use the CAP survey for their quality control. Furthermore, they can continuously monitor their systems throughout all testing phases as the survey has numbers of shipments a year and several specimens per each mailing. This helps in laboratory performance improvement. The Evaluation and Participant Summary (PSR) also effectively improves the laboratories' performance. CAP-accredited laboratories are required to participate in all survey programs concerning the test menu which they provide. Therefore, they have become accustomed to reviewing the evaluation and performing self-evaluation with a high usage rate of the Evaluation and PSR of the CAP survey. The questionnaire proved that performing the CAP survey properly enhanced the laboratories' quality control, and this meets the

  11. Genetic influences on conduct disorder.

    Science.gov (United States)

    Salvatore, Jessica E; Dick, Danielle M

    2016-06-24

    Conduct disorder (CD) is a moderately heritable psychiatric disorder of childhood and adolescence characterized by aggression toward people and animals, destruction of property, deceitfulness or theft, and serious violation of rules. Genome-wide scans using linkage and association methods have identified a number of suggestive genomic regions that are pending replication. A small number of candidate genes (e.g., GABRA2, MAOA, SLC6A4, AVPR1A) are associated with CD related phenotypes across independent studies; however, failures to replicate also exist. Studies of gene-environment interplay show that CD genetic predispositions also contribute to selection into higher-risk environments, and that environmental factors can alter the importance of CD genetic factors and differentially methylate CD candidate genes. The field's understanding of CD etiology will benefit from larger, adequately powered studies in gene identification efforts; the incorporation of polygenic approaches in gene-environment interplay studies; attention to the mechanisms of risk from genes to brain to behavior; and the use of genetically informative data to test quasi-causal hypotheses about purported risk factors.

    To review published works on the epidemiology, risk factors, protective factors, typologies, and genetic aspects of conduct disorder (CD). Findings from refereed journal articles and current texts in the field are briefly summarized. CD is commonly encountered in clinical practice. Factors strongly predictive of future delinquency include past offenses, antisocial peers, impoverished social ties, early substance use, male sex, and antisocial parents. Factors that moderately predict recidivism include early aggression, low socioeconomic status (SES), psychological variables such as risk taking and impulsivity, poor parent-child relationships, poor academic performance, early medical insult, and neuropsychological variables such as poor verbal IQ. Mildly predictive variables include other family characteristics such as large family size, family stress, discord, broken home, and abusive parenting, particularly neglect. Protective factors include individual factors such as skill competence (in social and other arenas), adult relationships, prosocial and proeducational values, and strong social programs and supports. We know a great deal about psychosocial risk factors for CD. Some research into protective factors and genetic contributions exists but is in its early stages. Future work will increase our knowledge about subtypes, developmental pathways, and CD treatment.

  13. Multifunctional scanning ion conductance microscopy.

    Science.gov (United States)

    Page, Ashley; Perry, David; Unwin, Patrick R

    2017-04-01

    Scanning ion conductance microscopy (SICM) is a nanopipette-based technique that has traditionally been used to image topography or to deliver species to an interface, particularly in a biological setting. This article highlights the recent blossoming of SICM into a technique with a much greater diversity of applications and capability that can be used either standalone, with advanced control (potential-time) functions, or in tandem with other methods. SICM can be used to elucidate functional information about interfaces, such as surface charge density or electrochemical activity (ion fluxes). Using a multi-barrel probe format, SICM-related techniques can be employed to deposit nanoscale three-dimensional structures and further functionality is realized when SICM is combined with scanning electrochemical microscopy (SECM), with simultaneous measurements from a single probe opening up considerable prospects for multifunctional imaging. SICM studies are greatly enhanced by finite-element method modelling for quantitative treatment of issues such as resolution, surface charge and (tip) geometry effects. SICM is particularly applicable to the study of living systems, notably single cells, although applications extend to materials characterization and to new methods of printing and nanofabrication. A more thorough understanding of the electrochemical principles and properties of SICM provides a foundation for significant applications of SICM in electrochemistry and interfacial science.

    Populations of deaf sign language users experience health disparities unmeasured by current public health surveillance. Population-specific health data are necessary to collaboratively identify health priorities and evaluate interventions. Standardized, reproducible, and language-concordant data collection in sign language is impossible via written or telephone surveys. Deaf and hearing researchers, community members, and other stakeholders developed a broad computer-based health survey based on the telephone-administered Behavioral Risk Factor Surveillance System. They translated survey items from English to sign language, evaluated the translations, and filmed the survey items for inclusion in their custom software. They initiated the second Rochester Deaf Health Survey in 2013 (n=211). Analyses (conducted in 2015) compared Rochester Deaf Health Survey 2013 findings with those of the Behavioral Risk Factor Surveillance System with the general adult population in the same community (2012, n=1,816). The Rochester Deaf Health Survey 2013 participants' mean age was 44.7 (range, 18-87) years. Most were deaf since birth or early childhood (87.1%) and highly educated (53.6% with ≥4 years of college). The median household income was <$35,000. The prevalence of current smokers was low (8.1%). Nearly all (93.8%) reported having health insurance, yet barriers to appropriate health care were evident, with high emergency department use (16.2% with two or more past-year visits) and 22.7% forgoing needed health care in the past year because of cost. Community-engaged research with deaf populations identifies strengths and priorities, providing essential information otherwise missing from existing public health surveillance, and forming a foundation for collaborative dissemination to facilitate broader inclusion of deaf communities.

    2006-01-01

    To determine how young people are likely to respond to a peer with mental illness, or who has severe behavioural problems. A mental health literacy survey was conducted with 1137 adolescents in years 8, 9 and 10 in South Australia and the Australian Capital Territory. Respondents were presented with a vignette of either a 16-year-old boy meeting criteria for conduct disorder or a 16-year-old girl meeting criteria for major depression. As part of the survey, respondents were asked to write in words what they would do if the person in the vignette was a friend of theirs and they wished to help. Responses were coded into categories. Over half the sample (53%) described positive social support as the only action they would take to help. A further 23% said they would engage an adult such as a parent, teacher or school counsellor to help with the situation. Those responding to the conduct disorder vignette were more likely to describe engaging an adult to help and males were more likely to say they would do nothing. Female students tended to answer differently to the conduct disorder and depression vignettes, while male students responded similarly to the two vignettes. Many adolescents do not respond to friends' distress in ways which are likely to facilitate appropriate help. Mental health education in schools should include skills for offering help and encouraging peers to seek help.

    Background E-Delphi is a way to access a geographically dispersed group of experts. It is similar to other Delphi methods but conducted online. E-research methodologies, such as the e-Delphi method, have yet to undergo significant critical discussion. Aim To highlight some of the challenges nurse researchers may wish to consider when using e-Delphi in their research. Discussion This paper provides details about the author's approach to conducting an e-Delphi study in which a group of health literacy nurse experts (n=41) used an online survey platform to identify and prioritise essential health literacy competencies for registered nurses. Conclusion This paper advances methodological discourse about e-Delphi by critically assessing an e-Delphi case study. The online survey platform used in this study was advantageous for the researcher and the experts: the experts could participate at any time and place where the internet was available; the researcher could efficiently access a national group of experts, track responses and analyse data in each round. Implications for practice E-Delphi studies create opportunities for nurse researchers to conduct research nationally and internationally. Before conducting an e-Delphi study, researchers should carefully consider the design and methods for collecting data, to avoid challenges that could potentially compromise the quality of the findings. Researchers are encouraged to publish details about their approaches to e-Delphi studies, to advance the state of the science.

    Methods of forming composites that incorporate networks of conductive polymer nanofibers are provided. Networks of less-than conductive polymers are first formed and then doped with a chemical dopant to provide networks of conductive polymers. The networks of conductive polymers are then incorporated into a matrix in order to improve the conductivity of the matrix. The formed composites are useful as conductive coatings for applications including electromagnetic energy management on exterior surfaces of vehicles.

  19. Israeli quality survey: research 'spin-offs'.

    Science.gov (United States)

    Bergman, R

    Quality assurance surveys in nursing are worthless unless the results can be translated into practical action. The author demonstrates how one such survey in Israel inspired Masters' students at Tel Aviv University to base their projects and theses on the survey findings, and produced intervention models and tools for improving care in several important areas of nursing. Encouraging the students to conduct these studies as 'spin-offs' from a major piece of national research has fostered a much broader understanding of quality assurance which has had a direct impact on patient care, and provides an example which nurses, educators and students in other countries can emulate.

    Full Text Available Research in Batangas started in the early 20th century and focused in the southwestern part of the province. The eastern part of Batangas due to research agenda was generally overlooked. To examine what the potential of this area, archaeological explorations were conducted in the municipalities of San Juan, Lobo, Taysan, and Padre Garcia. The team recorded 20 burial and settlement sites and some of these yielded datable materials belonging to the Developed Metal Age (100-400 AD, 15th century, and late 1800s. These new sites and dates will bring new perspectives on the archaeological history of Batangas.La investigación en Batangas se inició en el siglo XX y se centró en la parte suroeste de la provincia.

  5. Governing sexual behaviour through humanitarian codes of conduct.

    Science.gov (United States)

    Matti, Stephanie

    2015-10-01

    Since 2001, there has been a growing consensus that sexual exploitation and abuse of intended beneficiaries by humanitarian workers is a real and widespread problem that requires governance. Codes of conduct have been promoted as a key mechanism for governing the sexual behaviour of humanitarian workers and, ultimately, preventing sexual exploitation and abuse (PSEA). This article presents a systematic study of PSEA codes of conduct adopted by humanitarian non-governmental organisations (NGOs) and how they govern the sexual behaviour of humanitarian workers. It draws on Foucault's analytics of governance and speech act theory to examine the findings of a survey of references to codes of conduct made on the websites of 100 humanitarian NGOs, and to analyse some features of the organisation-specific PSEA codes identified. © 2015 The Author(s).

  6. Professional conduct of scientists during volcanic crises

    Stress during volcanic crises is high, and any friction between scientists can distract seriously from both humanitarian and scientific effort. Friction can arise, for example, if team members do not share all of their data, if differences in scientific interpretation erupt into public controversy, or if one scientist begins work on a prime research topic while a colleague with longer-standing investment is still busy with public safety work. Some problems arise within existing scientific teams; others are brought on by visiting scientists. Friction can also arise between volcanologists and public officials. Two general measures may avert or reduce friction: (a) National volcanologic surveys and other scientific groups that advise civil authorities in times of volcanic crisis should prepare, in advance of crises, a written plan that details crisis team policies, procedures, leadership and other roles of team members, and other matters pertinent to crisis conduct. A copy of this plan should be given to all current and prospective team members. (b) Each participant in a crisis team should examine his or her own actions and contribution to the crisis effort. A personal checklist is provided to aid this examination. Questions fall generally in two categories: Are my presence and actions for the public good? Are my words and actions collegial, i.e., courteous, respectful, and fair? Numerous specific solutions to common crisis problems are also offered. Among these suggestions are: (a) choose scientific team leaders primarily for their leadership skills; (b) speak publicly with a single scientific voice, especially when forecasts, warnings, or scientific disagreements are involved; (c) if you are a would-be visitor, inquire from the primary scientific team whether your help would be welcomed, and, in general, proceed only if the reply is genuinely positive; (d) in publications, personnel evaluations, and funding, reward rather than discourage teamwork.

  11. Loss of conductivity in operating room shoes.

    Kulis, E; Newell, J C

    1978-01-01

    The effect of dirt encountered during normal use on the conductivity of operating room footwear has been studied. Booties, sneakers, and shoes having relatively larger conductive area remained conductive throughout the testing period. Shoes and clogs having relatively smaller conductive contact area were found to lose conductivity sooner, and, in more cases, than any other type of footwear tested. The size of the conductive contact area appears to correlate with the length of time that conductive footwear will remain within resistance specification during use.

    Conduct problems and hyperactivity are frequent among children referred for sleep-disordered breathing (SDB), restless legs syndrome, or periodic leg movements during sleep (PLMS), but children not referred to sleep centers have received little study. Parents of children aged 2 to 14 years were surveyed at two general clinics between 1998 and 2000. A Pediatric Sleep Questionnaire generated validated scores for SDB and PLMS. The Conners Parent Rating Scale (CPRS-48) produced an age- and sex-adjusted Conduct Problem Index (CPI) and Hyperactivity Index. Parents of about 1,400 children were approached; those of 872 (62%) completed the surveys. Bullying and other specific aggressive behaviors were generally two to three times more frequent among 114 children at high risk for SDB than among the remaining children. An association between high CPI and SDB scores (p <.0001) retained significance after adjustment for sleepiness, high Hyperactivity Index, stimulant use, or PLMS scores. Analogous results were obtained for the association between high CPI and PLMS scores. Conduct problems were associated with symptoms of SDB, restless legs syndrome, and PLMS. Although these results cannot prove a cause-and-effect relationship, assessment for sleep disorders may provide a new treatment opportunity for some aggressive children.

    Tiruvallur District, South India, where one baseline tuberculosis (TB) disease prevalence survey followed by three repeat prevalence surveys were conducted every 2.5 years between 1999 and 2008, and where the DOTS strategy was implemented in 1999. To rule out the possibility that the observed decline in TB prevalence was influenced by conducting repeat prevalence surveys, we compared the findings from two surveys: the third repeat survey conducted in 2006-2008 and an independent single survey in a neighbouring area conducted in 2008-2009. An independent survey was conducted to estimate the prevalence of TB in the same district in 2008-2009 using a different set of villages and employing repeat survey methodology. The independent survey findings were compared with those of the third repeat survey. The estimated prevalence rate of culture- and smear-positive TB was respectively 401 per 100,000 and 186 per 100,000 population in the third repeat survey area. The corresponding rates were 340 and 184/100,000 in the independent survey area. The difference in prevalence was not significant (culture P = 0.09; smear P = 0.93). The estimated prevalence rates in the two different sample survey areas were comparable, indicating that the repeated prevalence surveys in the study area did not influence the observed decline in TB disease prevalence.
