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

    Many people in the world express the concern that global warming will become an increasingly serious problem. A rapid increase in population and demand for energy in the Asian region must be discussed in this context. Despite the forecast of an increase in demand for energy, the Asian region is short of oil and natural gas resources. In addition, only less energy can be supplied by renewable energy sources in the Asian region than in the other regions because of high population density. Nuclear energy is an important energy resource for fulfilling the future increasing energy demand in the Asian region and for contributing to the suppression of carbon dioxide emissions. In the Asian region alone, however, we cannot rely limitlessly on LWR which does not use plutonium. According to a scenario analysis, the total capacity of nuclear power plants in the Asian region would reach large scale and the cumulative amount of demand for natural uranium will increase to about 5 million tons in the Asian region alone. Just the nuclear power plants of this scale in Asia alone will rapidly consume the world's cheap natural uranium resources if we rely only on natural uranium. In the Asian region, few countries have embarked on nuclear power generation and the capacity of equipment is still small. Currently, however, many plans for nuclear power generation are being designed. Many Asian countries obviously consider nuclear power generation as a valid option. Many potential policies must be examined in the light of future uncertainty. In the future, both renewable energy and nuclear energy must be resorted to. When nuclear energy is utilized, the use of plutonium and FBR in the Asian region must be taken into account in order to attain continual growth and development. (author)

    Understanding the dynamics of Zika virus transmission and formulating rational strategies for its control require precise diagnostic tools that are also appropriate for resource-poor environments. We have developed a rapid and sensitive loop-mediated isothermal amplification (LAMP) assay that distinguishes Zika viruses of Asian and African lineages. The assay does not detect chikungunya virus or flaviviruses such as dengue, yellow fever, or West Nile viruses. The assay conditions allowed direct detection of Zika virus RNA in cultured infected cells; in mosquitoes; in virus-spiked samples of human blood, plasma, saliva, urine, and semen; and in infected patient serum, plasma, and semen samples without the need for RNA isolation or reverse transcription. The assay offers rapid, specific, sensitive, and inexpensive detection of the Asian-lineage Zika virus strain that is currently circulating in the Western hemisphere, and can also detect the African-lineage Zika virus strain using separate, specific primers.

    Development schedule, and natural gas resources available to Southeast Asian countries were discussed in view of the area's rapidly growing market for natural gas. As evidence, the increased regional trade and cooperation are evident in the form of organizations like the Association of South East Asian Nations (ASEAN) and Asia Pacific Economic Cooperation (APEC) Forum were cited. Liquid natural gas pipeline grids were about 1/3 complete at the time of writing. Further development and completion of this system was expected to occur over the next 3 decades. Integration of new and existing facilities were seen to be inevitable future developments. The potential for international movement of natural gas from producing countries to consuming countries was assessed and was expected to remain favourable in the long term

    The gypsy moth- Lymantria dispar (Linnaeus)-is a worldwide forest defoliator and is of two types: the European gypsy moth and the Asian gypsy moth. Because of multiple invasions of the Asian gypsy moth, the North American Plant Protection Organization officially approved Regional Standards for Phytosanitary Measures No. 33. Accordingly, special quarantine measures have been implemented for 30 special focused ports in the epidemic areas of the Asian gypsy moth, including China, which has imposed great inconvenience on export trade. The Asian gypsy moth and its related species (i.e., Lymantria monocha and Lymantria xylina ) intercepted at ports are usually at different life stages, making their identification difficult. Furthermore, Port quarantine requires speedy clearance. As such, it is difficult to identify the Asian gypsy moth and its related species only by their morphological characteristics in a speedy measure. Therefore, this study aimed to use molecular biology technology to rapidly identify the Asian gypsy moth and its related species based on the consistency of mitochondrial DNA in different life stages. We designed 10 pairs of specific primers from different fragments of the Asian gypsy moth and its related species, and their detection sensitivity met the need for rapid identification. In addition, we determined the optimal polymerase chain reaction amplification temperature of the 10 pairs of specific primers, including three pairs of specific primers for the Asian gypsy moth ( L. dispar asiatic ), four pairs of specific primers for the nun moth ( L. monocha ), and three pairs of specific primers for the casuarina moth ( L. xylina ). In conclusion, using our designed primers, direct rapid identification of the Asian gypsy moth and its related species is possible, and this advancement can help improve export trade in China.

  9. The Rapid Arctic Warming and Its Impact on East Asian Winter Weather in Recent Decade

    The Arctic is warming much more rapidly than the lower latitudes. In contrast to the rapid Arctic warming, in winters of the recent decade, the cold-air outbreaks over East Asia occur more frequently and stronger than in 1990s. By accompanying the snow over East Asia, the strong cold surges have led to a severe socio-economic impact. Such severe cold surges in recent decade over east Asia is consistent with the more dominant negative phase of the Arctic Oscillation (AO), that may be attributed by the Arctic amplification. In both observation-based reanalysis and numerical model experiments, the Arctic sea ice melting leads to the weakening of the AO polarity by reducing the meridional temperature gradient through a heat flux feedback. The Arctic warming and associated sea ice melting over the Kara-Barents area in late fall and early winter first release a lot of heat to the atmosphere from the ocean by a strong contrast in temperature and moisture and higher height anomaly is developed over the Kara/Barents and the Ural mountains The anomalous anticyclonic anomaly over the Arctic strengthen the Siberian High and at the same time the east Asian trough is developed over the western coast of the North Pacific. Through the passage between the margin of the Siberian High and east Asian tough, an extremely cold air is transported from east Siberia to east Asia for sometimes more than a week. Such a severe sold air brings about the moisture from nearby ocean, largely influencing the daily lives and economy in north East China, Korea, and Japan. The recent Arctic and associated sea ice melting is not only contributed to the local climate and weather, but also a severe weather in mid-latitudes through a modulation in polar vortex.

    At the 12th annual Asian Parliamentarians Meeting on Population and Development, co-sponsored by the Asian Population and Development Association (APDA) of Japan and the Philippine Legislative Committee on Population and Development (PLCPD), the adverse effect of population growth on economic development and the importance of improvements in women's status were central themes. Fukusaburo Maeda, President of APDA Japan, noted that an understanding of women's issues is key to solving global population problems. Numerous participants urged rapid implementation of plans outlined at recent conferences in Cairo and Beijing to empower women and involve them in all stages of the development process. Even issues of food security are linked to women's issues, since women are generally responsible for feeding their families. Participants voted to adopt the "Manila Resolution on Women, Gender, Population, and Development"--a call for social and economic empowerment of women and resources for gender-related programs. Dr. Patricia Licuanan, Chair of the UN Committee on the Status of Women, noted that men should not feel threatened by women holding positions of power; rather, they should welcome an equal partnership between men and women. In her closing address, Senator Leticia Ramos Shahani, Chair of PLCPD, stressed the importance of placing women's empowerment on various parliamentary agendas and commended APDA for its research and population-based surveys in Asia.

    In this commentary, we put forth an Asian Americanist perspective on child development that frames, expands upon, and at times challenges the contextual, conceptual, and methodological ideas put forward by Kiang et al., Mistry et al., and Yoshikawa et al. (this volume). This Asian Americanist perspective draws upon scholarship in Asian American Studies and critical race theory to bridge the historical, conceptual, and methodological contributions of the three articles. We also aim to challenge current and future generations of scholars studying Asian American child development to look at Asian American youth and families as autonomous, self-determining agents who are capable of challenging, resisting, and affecting change in a racialized society. © 2016 The Authors.

  16. Did China follow the East Asian development model?

    Boltho, Andrea

    2009-12-01

    Full Text Available China is located in East Asia and, just as Japan, Taiwan or (South Korea at earlier stages of their development, has now grown very rapidly for some three decades. That is not enough, however, for it to qualify for membership of the club. The East Asian development model has a number of additional and important characteristics. Four are selected for discussion: the almost constant encouragement given to investment, the manufacturing sector and external competitiveness, and pursued via a variety of fairly interventionist industrial, trade and financial policies; a concomitant belief in the virtues of intense domestic (Japan and Taiwan and foreign (Korea competition; a set of broadly sensible and appropriate macroeconomic policies; and a number of favourable (pre-conditions, such as the presence of a homogeneous population, a relatively high stock of human capital, reasonable income equality and fairly authoritarian governments. China, since reforms began in the late 1970s, has shared some of these characteristics, but not all. In particular, it is still much more of a command economy than the other three countries have ever been, yet, at the same time, has embraced globalization with, arguably, much greater enthusiasm than was done, in earlier times, by Japan, Taiwan or Korea. If China's experience, however, is compared with that of other, more or less successful, developing countries, the similarities with the East Asia development model would seem to dwarf such differences

  17. Association between voluntary/involuntary job loss and the development of stroke or cardiovascular disease: a prospective study of middle-aged to older workers in a rapidly developing Asian country.

    Full Text Available The aim of this research was to investigate the association between job loss and the development of stroke or cardiovascular disease among middle-aged to older individuals in Korea. We also examined how this relationship was modified by gender and the nature of the job loss.This study used samples from the first- to fourth-wave datasets from the Korean Longitudinal Study of Aging (KLoSA, which were collected in 2006, 2008, 2010, and 2012. The study collected data from a total of 10,254 subjects aged ≥ 45 years at baseline. After applying exclusion criteria, the final sample size for analysis consisted of 4,000 individuals. Information about employment status, development of stroke or cardiovascular disease, and covariates (age, income level, and behavioral factors was obtained. Cox proportional hazards models were used to evaluate the association between voluntary/involuntary job loss and the development of stroke or cardiovascular disease. We performed these analyses separately according to disease, gender, and the nature of the job loss.Involuntary job loss significantly increased the risk of stroke or cardiovascular disease among males (adjusted hazard ratio [HR]  = 3.560, 95% confidence interval [CI]  = 2.055-6.168. Voluntary retirement also increased the risk of cardiovascular disease or stroke among males (adjusted HR = 2.879, 95% CI = 1.533-5.409. Job loss was more closely associated with stroke than with cardiovascular disease (stroke, adjusted HR = 6.208, 95% CI = 2.417-15.943; cardiovascular disease, adjusted HR = 2.768, 95% CI = 1.402-5.465.Our findings suggest that both voluntary retirement and involuntary job loss increase the risk for stroke or cardiovascular disease in middle-aged to older individuals, especially males.

    Brazil and the State of Rio Grande do Sul are experiencing a period of rapid industrial development. Global investment has been forecast to reach $240 billion over the next five to seven years. This level of development is likely to result in a sharp increase in the consumption of plastic products made from olefins and from aromatic products. Accordingly, Copesul, the centre of raw materials for the State complex, is expected to increase its production of ethane from 685 tonnes to 1.13 million tonnes after 1999. The government has established a program of incentives to stimulate investment in third generation industries. Also, the State petrochemical industry has been rendered more competitive as a result of the purchase of the latest generation equipment. The principal challenges that exist for the petrochemical industry in Brazil and for that matter, around the world, are to reduce production costs and to preserve the natural environment. Another challenge, also world-wide, is to address the issue of plastic residues and to eliminate such residues through plastic recycling programs

  19. Trends and prospects of nuclear power development programs in the Asian countries

    1998-12-01

    This report is intended to look into the trends and prospects of nuclear power development programs in the Asian countries which will emerge as major business markets for the international nuclear industry and will seek to strengthen nuclear cooperation with Korea. In Asia, which accounts for about half of the world's population, there are many countries which have already expanded and are ready to embark on nuclear programs to meet increasing energy demands resulting from the rapidly growing economic development in the region. The Asian region will also emerge as a new area for economic development in the 21st century. The future demand for nuclear power programs will also increase in booming Asia where rapid industrialization has been in progress. The main constraints to nuclear power deployment in Asia include fund-raising for nuclear development, weakness of technical infrastructure and so on. In this regard, these problems need to be addressed to successfully implement nuclear programs in the region. This report could be used to establish national policies for nuclear cooperation and nuclear business with Asian countries expected to develop active nuclear power programmes in the future.

  1. The Asian Development Model and Mining Reforms in Indonesia

    Directory of Open Access Journals (Sweden)

    John McLaren

    2015-07-01

    Full Text Available The aim of this paper is to provide accounting, marketing, management, finance and legal professionals who are engaged with emerging economies with an introduction to the ‘Asian Development Model’ and to use the mining reforms in Indonesia as an example of the Model in operation. This will assist those professionals in recognising the challenges faced by businesses in Australia and New Zealand when governments in South East Asian countries attempt to ‘catch up’ to the developed world and at the same time attempt to spread the benefits of the development to their people. The paper argues that there is an Asian Development Model and that the Indonesian mining reforms, in particular the requirement over time for 51 percent Indonesian Government ownership and the ban on the export of unprocessed resources, represent an attempt by the Indonesian State to speed up industrialisation in their country and to spread more of the benefits from mining to ordinary citizens in the recently democratised and politically decentralised country. In attempting to show strength however, the Indonesian state is exposing some weakness. The impact on jobs, revenue and production has been adverse although Foreign Direct Investment has increased. This latter may be because it is foreign multinational mining companies who are better placed than local mining enterprises to build smelters. The success of developing mining might be at the expense of local capital. In other words state intervention does not always produce all of the desired outcomes. It is not a panacea.

  2. Overseas workers' remittances in Asian development.

    Stahl, C W; Arnold, F

    1986-01-01

    In recent years, overseas workers from Asia have been sending remittances of about $8 billion annually to their home countries. These remittances are an important source of precious foreign exchange for the major labor-exporting countries. The overall development impact of remittances, however, has not been well established. Remittances are spent primarily on day-to-day consumption expenditures, housing, land purchase, and debt repayment. Although only a small proportion of remittances are directed into productive investments, this does not warrant the conclusion that the developmental value of remittances is negligible. In fact, remittances spent on domestic goods and services Asia provide an important stimulus to indigenous industries and to the economies of the labor supplying countries. It is these broader macroeconomic benefits of remittances which seem to have been largely ignored in the literature, and this perhaps explains the pessimistic view of the developmental value of remittances. Reservations concerning the effects of remittance on the sending countries include the fears that 1) expenditure patterns of remittance receiving households may create a demonstration effect whereby nonmigrant households may increase consumption, 2) remittance inflow will increase income and wealth inequalities, 3) remittance expenditures may result in inflation, 4) remittances may produce only short-term fluctuations in long-term economic development, and 5) remittances may adversely affect agricultural development.

  3. Asian and African Development Trajectories Revisiting Facts and Figures

    Directory of Open Access Journals (Sweden)

    Gilles Carbonnier

    2013-05-01

    Full Text Available In today’s dominant discourse, the development trajectory of many East Asian countries is pictured as a success, whereas that of many sub-Saharan African countries is considered a failure. The Asian success stories often refer to the developmental state model, which highlights the pivotal role played by Asian political elites in catalyzing economic growth and broad-based development. The model includes economic liberalization and outward-oriented policies, with targeted support to – and protection of – strategic sectors and infant industries.How far is this underlying assumption supported by empirical evidence? This working paper examines a wide range of economic, social, institutional and governance indicators for a sample of six sub-Saharan and five South East Asian countries. Contrary to our research hypothesis, we did not find any significant difference in the level of government involvement in the domestic economy between the countries of the two regions, nor in the quality of institutions and governance indicators, nor in the share of imports and exports in GDP.Even if there are important gaps between the two regions, for instance with regard to the demographic transition, the agricultural sector or tertiary education, the picture is much more nuanced than portrayed by the dominant discourse. Our review of economic and socio-political indicators tells a rather different story, but not the whole story. Nevertheless, the indicators fail to take into account all the historical, institutional and structural factors that matter a great deal for development. Hence our analysis should be complemented by detailed country case studies to uncover the specific dynamics underlying different development trajectories and outcomes.

    Robotic surgery was started in the Department of Urology, Hospital Kuala Lumpur, in April 2004. We present our experience in developing the program and report the results of our first 50 cases of robotic radical prostatectomy. A three-arm da Vinci robotic system was installed in our hospital in March 2004. Prior to installation, the surgeons underwent training at various centers in the United States and Paris. The operating theatre was renovated to house the system. Subsequently, the initial few cases were done with the help of proctors. Data were prospectively collected on all patients who underwent robot-assisted radical prostatectomy for localized carcinoma of the prostate. Fifty patients underwent robot assisted radical prostatectomy from March 2004 to June 2005. Their ages ranged from 52 to 75 years, (average age 60.2 years). PSA levels ranged from 2.5 to 35 ng/ml (mean 10.6 ng/ml). Prostate volume ranged from 18 to 130 cc (average 32.4 cc). Average operating time for the first 20 cases was 4 h and for the next 30 cases was 2.5 h. Patients were discharged 1-3 days post-operatively. Catheters were removed on the fifth day following a cystogram. The positive margin rate as defined by the presence of cancer cells at the inked margin was 30%. Twenty-one patients had T1c disease and one had T1b on clinical staging. Of these, two were apical margin positive. Twenty-six patients had T2 disease and eight of them were apical margin positive. Two patients had T3 disease, one of whom was apical margin positive. Five patients (10%) had PSA recurrence. Five patients had a poorly differentiated carcinoma and the rest had Gleason 6 or 7. Eighty percent of the patients were continent on follow-up at 3 months. Of those who were potent before the surgery, 50% were potent at 3-6 months. The robotic surgery program was successfully implemented at our center on the lines of a structured program, developed at Vattikuti Urology Institute (VUI). We succeeded in creating a team and

    Full Text Available Abstract Background Since 2003, Asia-Pacific, particularly Southeast Asia, has received substantial attention because of the anticipation that it could be the epicentre of the next pandemic. There has been active investment but earlier review of pandemic preparedness plans in the region reveals that the translation of these strategic plans into operational plans is still lacking in some countries particularly those with low resources. The objective of this study is to understand the pandemic preparedness programmes, the health systems context, and challenges and constraints specific to the six Asian countries namely Cambodia, Indonesia, Lao PDR, Taiwan, Thailand, and Viet Nam in the prepandemic phase before the start of H1N1/2009. Methods The study relied on the Systemic Rapid Assessment (SYSRA toolkit, which evaluates priority disease programmes by taking into account the programmes, the general health system, and the wider socio-cultural and political context. The components under review were: external context; stewardship and organisational arrangements; financing, resource generation and allocation; healthcare provision; and information systems. Qualitative and quantitative data were collected in the second half of 2008 based on a review of published data and interviews with key informants, exploring past and current patterns of health programme and pandemic response. Results The study shows that health systems in the six countries varied in regard to the epidemiological context, health care financing, and health service provision patterns. For pandemic preparation, all six countries have developed national governance on pandemic preparedness as well as national pandemic influenza preparedness plans and Avian and Human Influenza (AHI response plans. However, the governance arrangements and the nature of the plans differed. In the five developing countries, the focus was on surveillance and rapid containment of poultry related transmission

    This is a report of development and psychometric testing of the East Asian Acculturation Measure-Chinese version (EAAM-C) scale. An instrument validation design with a cross-sectional survey was conducted. The process was carried in two phases. In Phase 1, Barry's East Asian Acculturation Measure was translated and back translated to evaluate its content, face validity, and feasibility validity. In Phase 2, the 16-item EAAM-C was pilot-tested among 485 female immigrants for test-retest reliability, internal consistency, theoretically-supported construct validity and concurrent validity. The pilot work and the survey results indicated the tools possessed adequate content and face validity. The Cronbach's Alphas for the EAAM-C was 0.72, and 0.76-0.79 for its subscales, and the correlation of test-retest reliability (at 3 weeks) was 0.75. After dropping one item, four theoretically-supported factors which explained 61.82% of the variance were abstracted using exploratory factor analysis: assimilation, integration, separation, and marginalization. Based on the underlying four-factor theoretical structures of the EAAM, the confirmatory factor analysis of the EAAM-C was further examined. The analysis revealed that the four-factor model was an acceptable fit for the data which demonstrated adequate finding in its construct validity. These factors were inter-correlated, and showed statistically significant correlation with the Chinese Health Questionnaire, indicating adequate concurrent validity. The scale shows acceptable validity and consistency, and suggests that immigrant acculturation is a complex construct. This quick evaluation instrument can be applied to assess clients' acculturation and in further developing certain interventions to improve their health.

    The current and ongoing expansion of urban areas worldwide represents the largest mass migration in human history. It is well known that the world's coastal zones are associated with large and growing concentrations of population, urban development and economic activity. Among coastal environments, deltas have long been recognized for both benefits and hazards. This is particularly true on the Asian megadeltas, where the majority of the world's deltaic populations reside. Current trends in urban migration, combined with demographic momentum suggest that the already large populations on the Asian megadeltas will continue to grow. In this study, we combine recently released gridded population density (circa 2010) with a newly developed night light change product (1992 to 2012) and a digital elevation model to quantify the spatial distribution of population and development on the nine Asian megadeltas. Bivariate distributions of population as functions of elevation and coastal proximity quantify potential exposure of deltaic populations to flood and coastal hazards. Comparison of these distributions for the Asian megadeltas show very different patterns of habitation with peak population elevations ranging from 2 to 11 m above sea level over a wide range of coastal proximities. Over all nine megadeltas, over 174 million people reside below a peak population elevation of 7 m. Changes in the spatial extent of anthropogenic night light from 1992 to 2012 show widely varying extents and changes of lighted urban development. All of the deltas except the Indus show the greatest increases in night light brightness occurring at elevations <10 m. At global and continental scales, growth of settlements of all sizes takes the form of evolving spatial networks of development. Spatial networks of lighted urban development in Asia show power law scaling properties consistent with other continents, but much higher rates of growth. The three largest networks of development in China all

    Current policy in Southeast Asian dental education focuses on high-quality dental services from new dental graduates and the free movement of dental practitioners across the region. The Southeast Asian Nations (ASEAN) Dental Councils have proposed the "Common Major Competencies for ASEAN General Dental Practitioners" to harmonize undergraduate dental education. This article discusses how the ASEAN competencies were developed and established to assist the development of general dental practitioners with comparable knowledge, skills, and attitudes across ASEAN. The competencies were developed through four processes: a questionnaire about current national oral health problems, a two-round Delphi process that sought agreement on competencies, a panel discussion by representatives from ASEAN Dental Councils, and data verification by the representatives after the meeting. Key themes of the ASEAN competencies were compared with the competencies from the U.S., Canada, Europe, Australia, and Japan. A total of 33 competency statements, consistent with other regions, were agreed upon and approved. Factors influencing the ASEAN competencies and their implementation include oral health problems in ASEAN, new knowledge and technology in dentistry, limited institutional resources, underregulated dental schools, and uneven distribution of dental practitioners. The ASEAN competencies will serve as the foundation for further developments in ASEAN dental education including policy development, curriculum revision, quality assurance, and staff development. Collaboration amongst stakeholders is essential for successful harmonization of ASEAN dental education.

    At the 2012 General Assembly of the International Astronomical Union (IAU), the Office of Astronomy for Development announced a number of exciting new partnerships to assist with the IAU's decadal strategic plan (2010-2020). These landmark decisions included establishing a new coordinating centre that aims at using astronomy as a tool for development in East Asia. The agreement covers two important functions. One is known as a Regional Node, which entails the coordination of astronomy-for-development activities in countries within the general geographical region of East Asia. The other is known as a Language Expertise Centre which deals with all aspects relating to (mainly) the Chinese language and culture. The impact of the latter may obviously spread well beyond the geographical region to other parts of the world. Here we provide an update of the achievements and aims of the East Asian Office of Astronomy for Development.

    We discuss the rapid development of a large scale data discovery service for the CMS experiment using modern AJAX techniques and the Python language. To implement a flexible interface capable of accommodating several different versions of the DBS database, we used a 'stack' approach. Asynchronous JavaScript and XML (AJAX) together with an SQL abstraction layer, template engine, code generation tool and dynamic queries provide powerful tools for constructing interactive interfaces to large amounts of data. We show how the use of these tools, with rapid development in a modern scripting language, improved the scalability and usability of the the search interface for different user communities.

    The goal of precision medicine is to separate patient populations into groups to ultimately provide customized care tailored to patients. In terms of precision medicine, ~540 million people in the world have a genetic variant of the aldehyde dehydrogenase 2 (ALDH2) enzyme causing a flushing response and tachycardia after alcohol consumption. The genetic variant is identified as ALDH2*2 and originates from East Asian descendants of the Han Chinese. The variant is particularly important to consider when discussing lifestyle choices with patients in terms of risk for developing specific diseases, preventative screening, and selection of medications for treatment. Here we provide examples why patients with an ALDH2*2 variant need more individualized medical management which is becoming a more standard practice in the precision medicine era.

    JPL is under contract, through NASA, with the US Army to develop a state-of-the-art Command Center System for the US European Command (USEUCOM). The Command Center System will receive, process, and integrate force status information from various sources and provide this integrated information to staff officers and decision makers in a format designed to enhance user comprehension and utility. The system is based on distributed workstation class microcomputers, VAX- and SUN-based data servers, and interfaces to existing military mainframe systems and communication networks. JPL is developing the Command Center System utilizing an incremental delivery methodology called the Rapid Development Methodology with adherence to government and industry standards including the UNIX operating system, X Windows, OSF/Motif, and the Ada programming language. Through a combination of software engineering techniques specific to the Ada programming language and the Rapid Development Approach, JPL was able to deliver capability to the military user incrementally, with comparable quality and improved economies of projects developed under more traditional software intensive system implementation methodologies.

    The diversity of circumstances and developmental outcomes among Asian American children and youth poses a challenge for scholars interested in Asian American child development. This article addresses the challenge by offering an integrated conceptual framework based on three broad questions: (a) What are theory-predicated specifications of contexts that are pertinent for the development of Asian American children? (b) What are the domains of development and socialization that are particularly relevant? (c) How can culture as meaning-making processes be integrated in conceptualizations of development? The heuristic value of the conceptual model is illustrated by research on Asian American children and youth that examines the interconnected nature of specific features of context, pertinent aspects of development, and interpretive processes. © 2016 The Authors.

    2008-02-27

    The green revolution of the 1960s and 1970s which resulted in dramatic yield increases in the developing Asian countries is now showing signs of fatigue in productivity gains. Intensive agriculture practiced without adherence to the scientific principles and ecological aspects has led to loss of soil health, and depletion of freshwater resources and agrobiodiversity. With progressive diversion of arable land for non-agricultural purposes, the challenge of feeding the growing population without, at the same time, annexing more forestland and depleting the rest of life is indeed daunting. Further, even with food availability through production/procurement, millions of marginal farming, fishing and landless rural families have very low or no access to food due to lack of income-generating livelihoods. Approximately 200 million rural women, children and men in India alone fall in this category. Under these circumstances, the evergreen revolution (pro-nature, pro-poor, pro-women and pro-employment/livelihood oriented ecoagriculture) under varied terms are proposed for achieving productivity in perpetuity. In the proposed 'biovillage paradigm', eco-friendly agriculture is promoted along with on- and non-farm eco-enterprises based on sustainable management of natural resources. Concurrently, the modern ICT-based village knowledge centres provide time- and locale-specific, demand-driven information needed for evergreen revolution and ecotechnologies. With a system of 'farm and marine production by masses', the twin goals of ecoagriculture and eco-livelihoods are addressed. The principles, strategies and models of these are briefly discussed in this paper.

    Although common mental disorder (CMD) is highly prevalent among South Asian immigrant women, they rarely seek mental treatment. This may be owing in part to the lack of conceptual synchrony between medical models of mental disorder and the social models of distress common in South Asian communities. Furthermore, common mental health screening and diagnostic measures may not adequately capture distress in this group. Community-based participatory research (CBPR) is ideally suited to help address measurement issues in CMD as well as to develop culturally appropriate treatment models. To use participatory methods to identify an appropriate, culturally specific mental health syndrome and develop an instrument to measure this syndrome. We formed a partnership between researchers, clinicians, and community members. The partnership selected a culturally specific model of emotional distress/illness, "tension," as a focus for further study. Partners developed a scale to measure Tension and tested the new scale on 162 Bangladeshi immigrant women living in the Bronx. The 24-item "Tension Scale" had high internal consistency (α = 0.83). On bivariate analysis, the scale significantly correlated in the expected direction with depressed as measured by the Patient Health Questionnaire (PHQ-2), age, education, self-rated health, having seen a physician in the past year, and other variables. Using participatory techniques, we created a new measure designed to assess CMD in an isolated immigrant group. The new measure shows excellent psychometric properties and will be helpful in the implementation of a community-based, culturally synchronous intervention for depression. We describe a useful strategy for the rapid development and field testing of culturally appropriate measures of mental distress and disorder.

  20. Rapid population growth and fragile environments: the sub-Saharan African and south Asian experience.

    1994-02-18

    Case studies of the world's two poorest regions, sub-Saharan Africa and South Asia, were used to illustrate the compromised standard of living of the poor and environmental damage due to continued rapid population growth. The conclusion was that the livelihoods of the poor should not be endangered for preserving the living standards of richer people. Nations must not ignore the challenges of reducing population growth as fast as can be achieved. The transitional period over the next 50 years is the main concern, because population growth rates will be slowing. Rural population growth is expected to decline from 60% of total population growth in South Asia to 7% between 2000 and 2025; similarly the decline in sub-Saharan Africa would be from 50% to 15%. Over the past 30 years, food production in South Asia has kept pace with population growth. Sub-Saharan Africa has adopted food importation to meet demand. African problems are a low resource base, faster population growth, and the fact that governments and individuals are too poor to maintain soil fertility. Long-term studies of how much soil depletion will occur are not available for these regions, and local area studies are not as pessimistic. Transition policies are needed to put "people first in terms of engineered or directed population and ecological change." The six main issues are the following: 1) the Brundtland Commission appropriately identified poverty as the main cause and effect of environmental degradation because of the threat to survival; 2) the verdict is still out about whether food production will keep pace with population growth through economic growth and investment in agriculture; 3) empirical research is needed to examine local social and regulatory institutions and the possibility of reinforcing these mechanisms rather than instituting central controls; 4) central coercion or modernizing economic policies can destroy local level controls; 5) famine is a complex ecological phenomenon and the

    This paper investigates the determinants of growth in the Asian developing economies. We use Bayesian model averaging (BMA) in the context of a dynamic panel data growth regression to overcome the uncertainty over the choice of control variables. In addition, we use a Bayesian algorithm to analyze a large number of competing models. Among the explanatory variables, we include a non-linear function of inflation that allows for threshold effects. We use an unbalanced panel data set of 27 Asian ...

    The risks and opportunities in the rapidly developing markets in Southeast Asia, China in particular, were discussed. It was asserted that no other region in the world can match the long-term market opportunities that China and Southeast Asia promise. The forces driving the economic development in Southeast Asia were described, including the great potential the region holds for the petrochemical industry. Graphs showing total polyethylene production vs. demand for year 2005 were included as illustrative examples. By 2005, China is projected to be importing almost one-half of the products it consumes. Every country with excess capacity will supply China with polyethylene. The political uncertainties that makes doing business in the region a high risk undertaking were reviewed, along with other risks relevant to the petrochemical industry such as (1) high capital costs, (2) over-building to the point that there is more supply than demand for the product, (3) low-cost producers may drive down prices to maintain market share, and (4) the uncertain nature of projections regarding economic growth and (5) inflated estimates of demand for petrochemicals. 1 tab., 4 figs

    In the first part, a contextual grid is built which aims at presenting the main impacts of development in developing countries. Some development trends, like energy consumption growth, environmental courses, economic growth and demographic development are analyzed. Then, a global modeling analysis of Kuznets' environmental curves and of development prospect is presented. The second part presents different types of policy instruments for environment protection, and the theoretical challenges and experience feedback of their implementation in OECD countries, in particular in the energy sector. It treats also of the energy-environment policy practices and of their environmental impacts on the economy, of the role of institutional factors in the environmental management in the fast developing Asian countries. The environmental management priorities in an integrated approach in these countries are presented and compared with environmental management experiences in the OECD countries. In the third part, the case study of the power industry sector in Vietnam aims at making an inventory of the emissions in a rapidly developing sector with important atmospheric emissions and at making a critical status of the evaluation instruments of environmental policies by comparing approaches based on 'bottom-up' and 'top-down' models. Finally, a model and a set of scenarios allowing to evaluate the economical and environmental consequences of the setting up of a sectoral policy in a transition economy context are presented.

    Science.gov (United States)

    1993-10-01

    The Organization of African Unity (OAU), the African Development Bank (ADB) and the UN Economic Commission for Africa (ECA) have criticized African governments for not taking the problem of unchecked population growth seriously enough. "Until recently most African governments did not view rapid population growth as a matter for concern," said the OAU assistant secretary-general for political affairs, Machivenyika Mapuranga, at a seminar on 'population and development'. The OAU estimates that an annual average population increase of 3.1% far outstrips Africa's economic growth, which in 1992 was less than 1%. Mapuranga acknowledged that cutting the population increase is an uphill struggle, especially among rural communities. African agriculture is largely labor intensive, sustained by smallholders, which encourages farmers to have more children. Like other wage earners, African farmers look to support from their family when they grow old and, for that reason, the number of children also counts. But with agricultural production growing at an average annual rate of 2.5%, self-sufficiency in food remains an elusive goal. Cities in sub-Saharan Africa are growing much faster than the overall rate of population increase of 3.1% per year. Between 1980 and 1988 the region's urban population increased at the rate of 6.9% a year. Urban areas now account for nearly 30% of the sub-Saharan Africa population, currently put at 680 million. By 2025, approximately 700 million people are expected to live in urban areas. Despite migration to towns, the rural population is expected to rise more than 68%, reaching over 590 million. full text

  9. Obesity and the metabolic syndrome in developing countries: focus on South Asians.

    With improvement in the economic situation, an increasing prevalence of obesity and the metabolic syndrome is seen in developing countries in South Asia. Particularly vulnerable population groups include women and children, and intra-country and inter-country migrants. The main causes are increasing urbanization, nutrition transition, reduced physical activity, and genetic predisposition. Some evidence suggests that widely prevalent perinatal undernutrition and childhood 'catch-up' obesity may play a role in adult-onset metabolic syndrome and type 2 diabetes. Data show that atherogenic dyslipidemia, glucose intolerance, thrombotic tendency, subclinical inflammation, and endothelial dysfunction are higher in South Asians than white Caucasians. Many of these manifestations are more severe even at an early age in South Asians than white Caucasians. Metabolic and cardiovascular risks in South Asians are also heightened by their higher body fat, truncal subcutaneous fat, intra-abdominal fat, and ectopic fat deposition (liver fat, muscle fat, etc.). Further, cardiovascular risk cluster manifests at a lower level of adiposity and abdominal obesity. The cutoffs of body mass index and waist circumference for defining obesity and abdominal obesity, respectively, have been lowered for Asians, and same has been endorsed for South Asians in the UK. The economic cost of obesity and related diseases in developing countries, having meager health budget, is enormous. Increasing awareness of these noncommunicable diseases and how to prevent them should be focus of population-wide prevention strategies in South Asian developing countries. Community intervention programs focusing on increased physical activity and healthier food options for schoolchildren are urgently required. Data from such a major intervention program conducted by us on adolescent urban schoolchildren in north India (project MARG) have shown encouraging results and could serve as a model for initiating such

  11. Household energy use in Asian cities: Responding to development success

    Science.gov (United States)

    Tyler, Stephen R.

    In the past 10-15 years, gains in household income and urban development in many countries in Asia have led to significant shifts in household use of fuels away from traditional, biomass-based household fuels to modern, fossil fuels. These results suggest that, while the global atmospheric emissions implications need further analysis, the local air quality effects of urban household fuel use changes have been positive. These changes also demonstrate improvements in living conditions, particularly for poor women and children most affected by indoor air quality. However, for electricity use, where there is evidence of dramatic increases in household consumption, the longer term implications for atmospheric emissions are more troubling. Rapid demand growth in the urban household sector is contributing to huge increases in thermal electric generating capacity needs in Asia. Improving technologies of electricity use in the household sector appears to be easily achievable and could be stimulated through market and policy mechanisms which have been used elsewhere. These measures offer the prospect of real environmental and economic gains without sacrificing lifestyle advantages of electrical appliance use in households.

    2015-12-01

    The Asian Forum for Polar Sciences (AFoPS), an international forum of Asian polar research institutes, was established for the advancement of polar sciences among its members in 2004. The Forum has served as an important medium of Asian collective endeavors for polar affairs in human and information exchange, research collaboration, and logistics cooperation for the last decade. The historical development of the AFoPS in retrospect can be divided into four phases: inception and establishment (2003-2004), growth and expansion (2005-2007), review and restructuring (2008-2011), and achievements and further measures (2012-2014). The progress of the AFoPS has not been linear and this trend will continue into the next decades. The Forum, however, clearly made achievements in this period of time, realizing multilateral research and logistics cooperation that would have been previously unimaginable; by doing so, it has laid the foundation for the future. Responsible for a great portion of the world's polar activities, the AFoPS will rise to meet the expectations of the world by producing notable research output, initiating international cooperative programs, and supporting non-polar Asian countries with education and research collaboration. These are the tasks of the AFoPS for the next decade and they require strategy that promotes and facilitates collaboration in a practical way and draws attention of non-polar Asian countries to the polar sciences.

  13. Dialysis and Quality of Dialysate in Southeast Asian Developing Countries

    2014-04-01

    Full Text Available Background: The number of dialysis patients has been increasing in Southeast Asia, but statistical data about these patients and on the quality of dialysates in Southeast Asian dialysis facilities are still imprecise. For this study, dialysis-related statistical data were collected in Southeast Asia. Methods: A survey of the quality of dialysates was carried out at 4 dialysis facilities in Vietnam and Cambodia. The dialysis patient survey included the numbers of dialysis facilities and patients receiving dialysis, a ranking of underlying diseases causing the initiation of dialysis, the number of patients receiving hemodialysis (HD/on-line hemodiafiltration/continuous ambulatory peritoneal dialysis, the number of HD monitoring devices installed, the cost of each session of dialysis (in USD, the percentage of out-of-pocket payments, and the 1-year survival rates of the dialysis patients (in percent. The dialysate survey covered the endotoxin (ET level and bacterial count in tap water, in water filtered through a reverse osmosis system and in dialysate. Results: In each of the countries, the most frequent reason for the initiation of dialysis is diabetes mellitus. HD is usually carried out according to the ‘reuse' principle. The 1-year survival rates are 70% in Myanmar and about 90% in the Philippines and Malaysia. The ET levels in standard dialysates were satisfactory at 2 facilities. The bacterial counts in dialysates were not acceptable at any of the facilities investigated. Conclusion: There is an urgent need to teach medical workers involved in dialysis how to prepare sterile and ET-free dialysates.

    In Asian developing countries, large amounts of municipal wastes are dumped into open dumping sites each day without adequate management. This practice may cause several adverse environmental consequences and increase health risks to local communities. These dumping sites are contaminated with many chemicals including brominated flame retardants (BFRs) such as polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs). BFRs may be released into the environment through production processes and through the disposal of plastics and electronic wastes that contain them. The purpose of this study was to elucidate the status of BFR pollution in municipal waste dumping sites in Asian developing countries. Soil samples were collected from six open waste dumping sites and five reference sites in Cambodia, India, Indonesia, Malaysia, and Vietnam from 1999 to 2007. The results suggest that PBDEs are the dominant contaminants in the dumping sites in Asian developing countries, whereas HBCD contamination remains low. Concentrations of PBDEs and HBCDs ranged from ND to 180 μg/kg dry wt and ND to 1.4 μg/kg dry wt, respectively, in the reference sites and from 0.20 to 430 μg/kg dry wt and ND to 2.5 μg/kg dry wt, respectively, in the dumping sites. Contamination levels of PBDEs in Asian municipal dumping sites were comparable with those reported from electronic waste dismantling areas in Pearl River delta, China. Copyright © 2012 Elsevier Ltd.

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

    For developing countries with budgetary and balance-of-payments gaps to meet, maintaining large stakes of external debt is not free of cost. Highly indebted countries have to set aside a sizeable fraction of their scarce resources to service their debt, which naturally affects their development spending in general and allocations for the social sector in particular. This study examines the behavior of seven developing Asian countries and analyzes the impact of public external debt on social s...

  18. WHITHER DEVELOPMENT? THE EFFECTS OF THE EURASIAN UNION ON THE CENTRAL ASIAN REPUBLICS

    2015-12-01

    Full Text Available In this paper I analyze the impact of the Eurasian Union on the Central Asian republics, with a focus on remittances trends. To this end I review at first the literature regarding the effects of the Customs Union on its members. Then, I assess the current state of the economies most likely to be affected by membership in the Eurasian Union, i.e. Tajikistan and Kyrgyzstan, whose specificity is their dependency on remittances. Secondly, I present a plausible scenario in regard to the influence of the formalization of this regional organization on the emerging Central Asian regional security subcomplex. I argue that the EEU is a hindrance towards the five Central Asian Republics’ evolving towards a regional security complex. Not only has it already distorted trade in the region, but it can also turn some presently frozen conflicts into security hotspots. I hold that the only way to spur development in the region is, internally, to diversify the economy, and, externally, to bring the five republics closer. I try to show that the Central Asian Republics should simultaneously pursue a switch from a balance of threat to regional integration and sustainable national development. Nonetheless, the EEU will have at best mixed effects when it comes to these necessities. Alternatively, China and the New Silk Road initiative that it endorses might contribute to de-securitizing some of the existing issues.

  1. Rapid and nondestructive detection of watercore and sugar content in Asian pear by near infrared spectroscopy for commercial trade

    Directory of Open Access Journals (Sweden)

    Ronnarit Rittiron

    2014-11-01

    Full Text Available Watercore and sugar content are internal qualities which are impossible for exterior determination. Therefore the aims of this study were to develop models for nondestructive detection of watercore and predicting sugar content in pear using Near Infrared Spectroscopy (NIR technique. A total of 93 samples of Asian pear variety "SH-078" were used. For sugar content, spectrum of each fruit was measured in the short wavelength region (700–1100 nm in the reflection mode and the first derivative of spectra were then correlated with the sugar content in juice determined by digital refractometer. Prediction equation was performed by multiple linear regression. The result showed Standard Error of Prediction (SEP = 0.58°Bx, and Bias=0.11. The result from t-test showed that sugar content predicted by NIR was not significantly different from the value analyzed by refractometer at 95% confidence. For watercore disorder, NIR measurement was performed over the short wavelength range (700–850 nm in the transmission mode. The first derivative spectra were correlated with internal qualities. Then principle component analysis (PCA and partial least squares discriminant analysis (PLSDA were used to perform discrimination models. The accuracy of the PCA model was greater than the PLSDA one. The scores from PC1 were separated into two boundaries, one predicted rejected pears with 100% classification accuracy, and the other was accepted pears with 92% accuracy. The high accuracy of sugar content determining and watercore detecting by NIR reveal the high efficiency of NIR technique for detecting other internal qualities of fruit in the future.

  2. Development of an Asian American parental racial-ethnic socialization scale.

    2016-07-01

    To develop a measure of parental racial-ethnic socialization that is appropriate for Asian American families. To test the reliability and validity of this new measure, we surveyed 575 Asian American emerging adults (49% female, 79% U.S. born). Using exploratory and confirmatory factor analyses, the results show 7 reliable subscales: maintenance of heritage culture, becoming American, awareness of discrimination, avoidance of other groups, minimization of race, promotion of equality, and cultural pluralism. Tests of factorial invariance show that overall, the subscales demonstrate, at minimum, partial metric invariance across gender, age, nativity, educational attainment, parent educational attainment, geographic region of residence, and Asian-heritage region. Thus, the relations among the subscales with other variables can be compared across these different subgroups. The subscales also correlated with ethnic identity, ethnic centrality, perceptions of discrimination, and pluralistic orientation, demonstrating construct validity. In an increasingly complex and diverse social world, our scale will be useful for gaining a better understanding of how Asian American parents socialize their children regarding issues of race, discrimination, culture, and diversity.

    At the 2012 General Assembly of the International Astronomical Union (IAU), the Office of Astronomy for Development (OAD) programme announced a number of exciting new partnerships to assist with the IAU's decadal strategic plan (2010-2020). These landmark decisions included establishing a new coordinating centre that aims at using astronomy as a tool for development in East Asia. The agreement covers two important functions. One is known as a Regional Node, which entails the coordination of astronomy-for-development activities in countries within the general geographical region of East Asia (in first instance China, Mongolia and the DPRK, but without placing firm geographical limits on the region). The other is known as a Language Expertise Centre which will deal with all aspects relating to (mainly) the Chinese language and culture. The impact of the latter may obviously spread well beyond the geographical region to other parts of the world.

  11. Is rapid development of nuclear power purposeful

    Energy Technology Data Exchange (ETDEWEB)

    1977-01-01

    The questions of the development of nuclear energy are discussed with regard to the efficacy of investments. The results are given of studies carried out at the nuclear research institute in Juelich in the FRG. At the estimated 25 years' service-life of the reactor and 0.2% uranium concentration in ore the following results were obtained: Total energy consumption for the construction and operation of a light water reactor power plant makes up 4.6% of the total power production, and in high-temperature reactors it amounts to 3.5%, both with uranium enrichment by the diffusion process. In uranium enrichment by centrifugal technology, consumption drops to 1.25% for LWRms and to 0.9% for high-temperature reactors, in fast breeder reactors it makes up only 0.8% of the total power production of the nuclear power plant. The period during which a nuclear power plant produces the amount of power consumed in construction and operation is 1.2 to 2.5 months which makes it less costly and more economical than any power plant burning coal minus the negative environmental impacts of such power plants.

  12. URBAN TRANSPORT AND LOCAL GOVERNANCE IN ASIAN DEVELOPING COUNTRIES

    2004-01-01

    This paper comprises a GIS-based land use analysis on the relationship between urbanization and transport infrastructure development, b GPS-based travel behavior survey, and c interview survey on residents' satisfaction with transport infrastructures and services. It was shown that the current land use patterns largely differ depending on the existence of agricultural infrastructure development in the pre-urbanized stage. It was also confirmed by a GPS-based travel survey that travel behavior patterns in scattered development areas are significantly different from those in orderly development areas. The former areas lack not only road space but also a structured hierarchy of networks, resulting in inefficient travel behaviors with low speed and detours. The GPS survey gave clearer pictures to grasp the relationship between travel patterns of residents and their demand for the improvement of local transport services. It was indicated that local governments who are responsible for these demands often fail to meet them due to financial and institutional limitations of the current system.

  14. The Development of White-Asian Categorization: Contributions from Skin Color and Other Physiognomic Cues.

    Directory of Open Access Journals (Sweden)

    Yarrow Dunham

    Full Text Available We examined the development of racial categorizations of faces spanning the European-East Asian ("White-Asian" categorical continuum in children between the ages of four and nine as well as adults. We employed a stimulus set that independently varied skin color and other aspects of facial physiognomy, allowing the contribution of each to be assessed independently and in interaction with each other. Results demonstrated substantial development across this age range in children's ability to draw on both sorts of cue, with over twice as much variance explained by stimulus variation in adults than children. Nonetheless, children were clearly sensitive to both skin color and other aspects of facial physiognomy, suggesting that understanding of the White-Asian category boundary develops in a somewhat different way than understanding of the White-Black category boundary, in which attention to features other than skin color appear only somewhat later. Discussion focuses on the implications of these findings for theories of social categorization.

    Directory of Open Access Journals (Sweden)

    Atul kohli

    2012-12-01

    Full Text Available When compared to Latin America, Asian economies since 1980 have grown faster and have done so with relatively modest inequalities. Why? A comparison of Asia and Latin America underlines the superiority of the nationalist capitalist model of development, which has often been pursued more explicitly in Asia, over that of a dependent capitalist model, which has often been pursued in Latin America. In comparison to Latin America, the Asian model has facilitated higher and less volatile rates of economic growth and a greater political room to pursue social democratic policies. The "tap root" of these alternate pathways is relative autonomy from global constraints: states and economies in Asia have been more nationalist and autonomous than in Latin America.

    Choi, Andrew Young; Israel, Tania; Maeda, Hotaka

    2017-01-01

    This article presents the development and psychometric evaluation of the Internalized Racism in Asian Americans Scale (IRAAS), which was designed to measure the degree to which Asian Americans internalized hostile attitudes and negative messages targeted toward their racial identity. Items were developed on basis of prior literature, vetted through expert feedback and cognitive interviews, and administered to 655 Asian American participants through Amazon Mechanical Turk. Exploratory factor analysis with a random subsample (n = 324) yielded a psychometrically robust preliminary measurement model consisting of 3 factors: Self-Negativity, Weakness Stereotypes, and Appearance Bias. Confirmatory factor analysis with a separate subsample (n = 331) indicated that the proposed correlated factors model was strongly consistent with the observed data. Factor determinacies were high and demonstrated that the specified items adequately measured their intended factors. Bifactor modeling further indicated that this multidimensionality could be univocally represented for the purpose of measurement, including the use of a mean total score representing a single continuum of internalized racism on which individuals vary. The IRAAS statistically predicted depressive symptoms, and demonstrated statistically significant correlations in theoretically expected directions with four dimensions of collective self-esteem. These results provide initial validity evidence supporting the use of the IRAAS to measure aspects of internalized racism in this population. Limitations and research implications are discussed.

    2014-01-01

    The purpose of this paper is to provide a review of the current literature uncovering specific factors associated with self-harm and suicidality among young Asian American women, as well as to present the Fractured Identity Model as a framework for understanding these factors. This paper offers concrete suggestions for the development of culturally competent interventions to target suicidality, substance abuse, and mental illness among young Asian American women. Empirical studies and theory-based papers featured in peer-reviewed journals between 1990 and 2014 were identified through scholarly databases, such as PubMed, MEDLINE, PsycINFO, JSTOR, and Google Scholar. We identified several factors associated with suicidality among young Asian American women: (1) family dynamics, or having lived in a household where parents practice "disempowering parenting styles," (2) substance use/abuse, and (3) untreated mental illness(es), which are exacerbated by the stigma and shame attached to seeking out mental health services. The Fractured Identity Model by Hahm et al. (2014) is presented as a possible pathway from disempowering parenting to suicidal and self-harm behaviors among this population, with substance abuse playing a significant mediating role. Research limitations/implications - Our review focused on Asian American women, substance use among Asian Americans, and mental health among Asian Americans. Literature that focused on Asians living in Asia or elsewhere outside of the USA was excluded from this review; the review was limited to research conducted in the USA and written in the English language. The complex interplay among Asian American culture, family dynamics, gender roles/expectations, and mental health justifies the development of a suicide and substance abuse intervention that is tailored to the culture- and gender-specific needs of Asian Pacific Islander young women. It is imperative for professionals in the fields of public health, mental health

    Full Text Available Contemporary urbanization appears as a conundrum especially in developing nations. This study will act as an accelerator to spill out snags caused by urbanization with a new approach in the development of sustainable infrastructure through Public–Private Partnerships (3Ps. This study first explains the complications generated by rapid urbanization in different infrastructural sectors in South Asian mega cities like Dhaka and Lahore. Second, the findings of the study elaborate on a new mechanism to adapt to Sustainable Development Goal 11 declared by the United Nations with the engagement of different stake holders working in different silos through 3Ps (like BOT, BOOT, BLT, DBF, PFI etc.. This study uses case studies as part of the research mixed methodology. Studies on Dhaka and Lahore including multi projects through 3Ps, and a detailed questionnaire survey based on critical risk factors from the Meta review of 3P literature are presented to establish the current status of sustainable development goals. This paper primarily contributes in two ways. First, by providing a new direction to policy makers to devise policies using a twofold approach i.e., grasp urbanization with sustainable infrastructure delivery by sustainable enactment of 3P projects. Second, bridge the knowledge gap by identifying the risk factors in the sustainable establishment of 3P projects in developing nations.

  3. Asian river fishes in the Anthropocene: threats and conservation challenges in an era of rapid environmental change.

    Science.gov (United States)

    Dudgeon, D

    2011-12-01

    This review compares and contrasts the environmental changes that have influenced, or will influence, fishes and fisheries in the Yangtze and Mekong Rivers. These two rivers have been chosen because they differ markedly in the type and intensity of prevailing threats. The Mekong is relatively pristine, whereas the Three Gorges Dam on the Yangtze is the world's largest dam representing the apotheosis of environmental alteration of Asian rivers thus far. Moreover, it is situated at the foot of a planned cascade of at least 12 new dams on the upper Yangtze. Anthropogenic effects of dams and pollution of Yangtze fishes will be exacerbated by plans to divert water northwards along three transfer routes, in part to supplement the flow of the Yellow River. Adaptation to climate change will undoubtedly stimulate more dam construction and flow regulation, potentially causing perfect storm conditions for fishes in the Yangtze. China has already built dams along the upper course of the Mekong, and there are plans for as many as 11 mainstream dams in People's Democratic Republic (Laos) and Cambodia in the lower Mekong Basin. If built, they could have profound consequences for biodiversity, fisheries and human livelihoods, and such concerns have stalled dam construction. Potential effects of dams proposed for other rivers (such as Nujiang-Salween) are also cause for concern. Conservation or restoration measures to sustain some semblance of the rich fish biodiversity of Asian rivers can be identified, but their implementation may prove problematic in a context of increasing Anthropocene alteration of these ecosystems. © 2011 The Author.

    The main purpose of this paper is to find the effects of financial development, income inequality, energy usage, and per capita GDP on carbon dioxide (CO 2 ) emissions as well the environmental Kuznets curve (EKC) for the three developing Asian countries-Bangladesh, India, and Pakistan. Panel data during the period 1980-2014 and the Stochastic Impacts by Regression on Population, Affluence, and Technology model with fully modified ordinary least squares (FMOLS) are employed for empirical investigation. The results show that financial development has a significant negative relationship with CO 2 emission in the three selected Asian countries with the exception of India. The results further reveal that income inequality in Pakistan and India reduce CO 2 emission, while the result for Bangladesh is opposite. Likewise, energy usage has a significant positive effect on CO 2 emission in Bangladesh, Pakistan, and India. Our empirical analysis based on long-run and short-run elasticity appraisal suggests the validation of the EKC in Pakistan and India. The study findings recommend an important policy insinuation. The study suggests introducing a motivational campaign for the inhabitant towards utilization of high-efficiency electrical appliances, constructing mutual cooperation for economic development rather involve in winning development race, and introducing effective pollution absorption measures along with big projects.

  5. Financial Development and Output Growth: A Panel Study for Asian Countries

    2012-03-01

    Full Text Available This paper investigates the relationship between financial markets and output growth for a panel of 27 Asian countries over 1960-2009. It utilizes the recently-developed panel cointegration techniques to test and estimate the long-run equilibrium relationship between real GDP and financial development proxies. Real GDP and financial development variables are found to have unit roots and to be cointegrated, based on various panel unit root tests and panel cointegration tests. We find that there is a statistically significant positive bi-directional cointegrating relationship between financial development and output growth by three distinct methods of panel cointegration estimation. Empirical findings suggest that financial market development promotes output growth and in turn output growth stimulates further financial development.

    'Development' is to improve the quality of people's lives by creating an environment for them to engage in a wide range of activities, to be healthy and well nourished, to be knowledgeable and to be able to participate in the community life. The Human Development Index (HDI) is a multi-dimensional index of development as it is the combination of three development indices- health index, education index and income index. This article attempts to compare the HDI and its components between various South East Asian countries. Secondary data is used. India's position on the HDI scale is equivalent to the South East Asian average and rank 134 out of more than 190 countries. In South East Asia, India stood fifth in HDI, behind Sri Lanka, Thailand, Maldives and Indonesia. Country has launched several schemes and programs to improve the health indicators, to provide elementary education to every child and to alleviate poverty.

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

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

    The International Astronomical Union (IAU) announced its Strategic Plan on Astronomy for Development in 2009, during the International Year of Astronomy (IYA). One of its main components was the creation of the Office of Astronomy for Development (OAD) and corresponding Regional Offices (ROADs) for implementation and coordination of its aims. The OAD was created in Cape Town, South Africa and later on ROADs were created in 8 regions. Since 2015, Armenia hosts one of them, IAU South West Asian (SWA), later renamed to South West and Central Asian (SWCA) ROAD. At present, already 6 countries have officially joined (Armenia, Georgia, Iran, Kazakhstan, Tajikistan, and Turkey), but the Office serves for a rather broad region, from Eastern Europe to Central Asia. Armenia's geographical location and its historical role in astronomy (both for well-known archaeoastronomical heritage and the presence of the famous Byurakan Astrophysical Observatory (BAO) founded by Viktor Ambartsumian in 1946) serve as a link between Europe and Eastern Partnership countries, Middle East and Asia in general. We run activities in 3 directions, Task Forces (TF): TF1 Universities and Research, TF2 Children and Schools and TF3 Public Outreach. We present our projects and all other accomplishments and discuss the role of our ROAD in maintaining contacts and development of astronomy in the region, as well as contacts between Europe and the Eastern Partnership countries. Most up-to-date information about the IAU SWCA ROAD is available on its webpage at http://iau-swa-road.aras.am/eng/index.php.

    The developing countries of Asia are amongst the largest contributors to the anthropogenic emissions of greenhouse gases as well as being amongst those most likely to be impacted by global climate change. There are at present no legal requirements for the Asian developing countries to reduce their emissions, however, the medium and long-term impact of global climate change is likely to be proportionately larger for the developing countries than for the industrialized countries, since the latter have the resources to reduce the adverse impacts. Therefore, it is of great interest of the developing countries, as well as the rest of the world, to have longer-term goals for stabilizing their greenhouse gas emissions, and taking actions during the medium term to achieve these goals. Asia is home to about 50% of the world's population, and there is great variation in the levels of industrialization and contribution to greenhouse gas emissions. A differentiated strategy for addressing concerns related to global climate change may be appropriate for the Asian developing countries at this time. Some elements of this strategy are discussed in this paper. Development in energy technology present several attractive options for the developing countries. However, their introduction and successful use depends at least as much on the existence of the necessary infrastructure as on the attractiveness of the technologies themselves. It is suggested that international and bilateral development agencies, as well as the countries themselves, consider the accelerated development of such infrastructure as a major way to contribute to the efforts to address global climate change.

    Studies of serum angiotensin converting enzyme (SACE) activity and its association with ACE gene insertion/deletion (I/D) polymorphism in relation to sarcoidosis have yielded variable results. This has been attributed to possible ethnic differences. Present study was designed to evaluate the relationship between I/D polymorphism and susceptibility to develop sarcoidosis and its effect on SACE activity and disease course in Asian Indian patients with sarcoidosis. ACE genotyping was performed in 72 consecutive patients with sarcoidosis and 199 controls (96 normal healthy individuals and 103 tuberculosis patients taken as disease controls). SACE activity was determined in all patients with sarcoidosis. Various parameters were compared amongst patients with different genotypes as well as between sarcoidosis and control groups. Gene frequency of I and D in control group was 0.6 and 0.4, whereas in patients with sarcoidosis it was 0.35 and 0.65 respectively (p SACE activity was highest in patients with DD genotype and followed an order of DD > ID > II. Good response to initial corticosteroids was seen in 6 of 6 (100%) patients with II genotype whereas in only 32 of 37 (84%) with ID and 16 of 25 (64%) with DD (p = 0.013). In Asian Indian population 'D' allele is associated with an increased risk for development of sarcoidosis and patients with 'D' allele show poor response to corticosteroids.

    The rapid drainage of supraglacial lakes injects substantial volumes of water to the bed of the Greenland ice sheet over short timescales. The effect of these water pulses on the development of basal hydrological systems is largely unknown. To address this, we develop a lake drainage model incorporating both (1) a subglacial radial flux element driven by elastic hydraulic jacking and (2) downstream drainage through a linked channelized and distributed system.

    Combustion in high-preheat and low oxygen concentration atmosphere is one of the attractive measures to reduce nitric oxide emission as well as greenhouse gases from combustion devices, and it is expected to be a key technology for the industrial applications in heating devices and furnaces. Before proceeding to the practical applications, we need to elucidate combustion characteristics of non-premixed and premixed flames in high-preheat and low oxygen concentration conditions from scientific point of view. For the purpose, we have developed a special mixing nozzle to create a homogeneous mixture of fuel and air by rapid mixing, and applied this rapidmixing nozzle to a Bunsen-type burner to observe combustion characteristics of the rapid-mixture. As a result, the combustion of rapid-mixture exhibited the same flame structure and combustion characteristics as the perfectly prepared premixed flame, even though the mixing time of the rapid-mixing nozzle was extremely short as a few milliseconds. Therefore, the rapid-mixing nozzle in this paper can be used to create preheated premixed flames as far as the mixing time is shorter than the ignition delay time of the fuel

  16. Development of a Fluvial Egg Drift Simulator to evaluate the transport and dispersion of Asian carp eggs in rivers

    Asian carp are migrating towards the Great Lakes and are threatening to invade this ecosystem, hence there is an immediate need to control their population. The transport of Asian carp eggs in potential spawning rivers is an important factor in its life history and recruitment success. An understanding of the transport, development, and fate of Asian carp eggs has the potential to create prevention, management, and control strategies before the eggs hatch and develop the ability to swim. However, there is not a clear understanding of the hydrodynamic conditions at which the eggs are transported and kept in suspension. This knowledge is imperative because of the current assumption that suspension is required for the eggs to survive. Herein, FluEgg (Fluvial Egg Drift Simulator), a three-dimensional Lagrangian model capable of evaluating the influence of flow velocity, shear dispersion and turbulent diffusion on the transport and dispersal patterns of Asian carp eggs is presented. The model's variables include not only biological behavior (growth rate, density changes) but also the physical characteristics of the flow field, such as mean velocities and eddy diffusivities. The performance of the FluEgg model was evaluated using observed data from published flume experiments conducted in China with water-hardened Asian carp eggs as subjects. FluEgg simulations show a good agreement with the experimental data. The model was also run with observed data from the Sandusky River in Ohio to provide a real-world demonstration case. This research will support the identification of critical hydrodynamic conditions (e.g., flow velocity, depth, and shear velocity) to maintain eggs in suspension, assist in the evaluation of suitable spawning rivers for Asian carp populations and facilitate the development of prevention, control and management strategies for Asian carp species in rivers and water bodies.

  17. Petroleum product pricing in Asian developing countries: Lessons from the past and future issues

    Bhattacharyya, S.C.

    1997-01-01

    This paper looks at the pricing of petroleum products in ten Asian developing countries using a data series for 1973--1992. Prices of petroleum products are compared with international prices. Differential prices are measured with respect to diesel prices. It is found that energy prices are used as instruments for revenue earnings. Pricing policies vary widely among countries and neighbors have different fuel prices. Countries try to align the local prices of petroleum products in line with international prices but with a lag of 1--2 years. The wave of liberalization and privatization is sweeping many developing countries. Additionally, environmental issues are gaining importance even in developing countries. The paper also discusses these emerging issues that need to be taken into account in the petroleum product pricing

    This article reports the development and psychometric properties of the Interpersonal Shame Inventory (ISI), a culturally salient and clinically relevant measure of interpersonal shame for Asian Americans. Across 4 studies involving Asian American college students, the authors provided evidence for this new measure’s validity and reliability. Exploratory factor analyses and confirmatory factor analyses provided support for a model with 2 correlated factors: external shame (arising from concerns about others’ negative evaluations) and family shame (arising from perceptions that one has brought shame to one’s family), corresponding to 2 subscales: ISI-E and ISI-F, respectively. Evidence for criterion-related, concurrent, discriminant, and incremental validity was demonstrated by testing the associations between external shame and family shame and immigration/international status, generic state shame, face concerns, thwarted belongingness, perceived burdensomeness, self-esteem, depressive symptoms, and suicide ideation. External shame and family shame also exhibited differential relations with other variables. Mediation findings were consistent with a model in which family shame mediated the effects of thwarted belongingness on suicide ideation. Further, the ISI subscales demonstrated high alpha coefficients and test–retest reliability. These findings are discussed in light of the conceptual, methodological, and clinical contributions of the ISI. PMID:24188650

    High-resolution temperature records spanning the last deglaciation from low latitudes are scarce; however, they are important for understanding the rapid propagation of abrupt climate events throughout the Northern Hemisphere and the tropics. Here, we present a branched GDGTs-based temperature reconstruction from the sediments of Maar Lake Huguangyan in tropical China. The record reveals that the mean temperature during the Oldest Dryas was 17.8 °C, which was followed by a two-step increase of 2-3 °C to the Bølling-Allerød, a decrease to 19.8 °C during the Younger Dryas, and a rapid warming at the onset of the Holocene. The Oldest Dryas was about 2 °C warmer than the Younger Dryas. The reconstructed temperature was weighted towards the wintertime since the lake is monomictic and the mixing process in winter supplies nutrients from the lake bottom to the entire water column, greatly promoting biological productivity. In addition, the winter-biased temperature changes observed in the study are more distinctive than the summer-biased temperature records from extra-tropical regions of East Asia. This implies that the temperature decreases during abrupt climatic events were mainly a winter phenomenon. Within the limits of the dating uncertainties, the broadly similar pattern of winter-weighted temperature change observed in both tropical Lake Huguangyan and in Greenland ice cores indicates the occurrence of tightly-coupled interactions between high latitude ice sheets and land areas in the tropics. We suggest that the winter monsoon (especially cold surges) could play an important role in the rapid transmission of the temperature signal from the Arctic to the tropics.

  20. Rapid Development, Build-Out Ratio and Subsequent Neighborhood Turnover

    2018-04-01

    Full Text Available Neighborhood development is primarily comprised of structural elements that include design elements, nearby amenities and ecological attributes. This paper assumes that the process of development itself also influences the character of the neighborhood—specifically, that the rate of development and build-out ratio influences neighborhood turnover. While the structural components clearly set a framework for development, the process of development expresses the character of the neighborhood in subtle messages conveyed through the market. Neighborhoods in the rapidly growing university town of College Station, Texas are analyzed in terms of neighborhood design, nearby amenities and landscape ecology components. Residential property records are used to characterize each neighborhood in terms of the rate of development and current build-out ratio. The multivariate analysis indicates that the development rate increases subsequent neighborhood turnover rates while the build-out ratio decreases it.

  3. "Clutching a knifeblade": human rights and development from Asian women's perspective.

    A brief, vivid portrait of the human rights conditions for women in Asia was presented: "kapit sa patalim" or utter despair, urban migration, export processing zones, tourism and prostitution, political repression, and military sexual slavery. Advocates of women's human rights for Asian women must contend with patriarchal and male-dominated systems that oppress and exploit women to a much greater extent than men. Liberation from these systems and the domination and exploitation by wealthier nations must be a goal of a new economic world order. Unjust and repressive structures must be destroyed, and equitable distribution of wealth and democracy and popular initiatives promoted. The status of women must be raised to coequal status with men. The most important objective of human rights advocates should be the empowerment of women at the individual, community, national, regional, and international level. The Asian Women's Human Rights Council was established as an addition to 3 already operating regional commissions of women's organizations. The aim was not just to describe women as victims, but to pressure development activity to account for women's human rights. Sex tribunals have been scheduled between 1993 and 1994 to address the following issues: 1) sex trafficking (Japan, May 1993); 2) violence against women (Pakistan, December 1993); 3) militarism, environment, and violence against women (Korea, March 1994); 4) crimes of development against women in Asia (India); 5) religion and violence against women (Malaysia, 1994); and 6) indigenous women (December 1994). Women were victims when Filipino domestic workers were stranded and raped in Iraq during the chaos of war, when girls from landless peasant families migrated near Clark Air Force Base to earn a living as prostitutes for US servicemen, when women were forced to work 36-hour shifts in foreign-owned garment factories in Bataan, when women migrated for work, and when women were abused and battered in

    To study the postpartum conversion of gestational diabetes mellitus (GDM) to different types of diabetes among Asian Indian women. Using data from electronic medical records, 418 women with GDM seen at a tertiary diabetes care center for diabetes in Chennai in South India between 1991 and 2014 were evaluated for development of diabetes postpartum. Of the 418 GDM women followed up postpartum, 388 progressed to diabetes. Of these 359 (92.5%) developed type 2 diabetes (T2DM) and 29 women (7.5%) developed type 1 diabetes (T1DM). The median time to development of T1DM was 2 years (interquartile range 2 [IQR]) while for T2DM it was 5 years (IQR 6). Women who developed T1DM had significantly lower mean body mass index (BMI) (20.4 ± 2.8 vs. 27.5 ± 4.4 kg/m 2 , P = 0.001), and higher fasting plasma glucose (222 ± 105 vs. 165 ± 62 mg/dl P = 0.008) and glycated hemoglobin levels (10.2 ± 2.7 vs. 8.5 ± 2.1% P women who developed T1DM. A small but significant proportion of women with GDM progress to T1DM postpartum. Measurement of GAD antibodies in leaner women with more severe diabetes could help to identify women who are likely to develop T1DM and thus prevent their presentation with acute hyperglycemic emergencies after delivery.

    2017-12-01

    The global decline of in situ observations associated with the increasing ability to monitor surface water from space motivates the creation of data assimilation algorithms that merge computer models and space-based observations to produce consistent estimates of terrestrial hydrology that fill the spatiotemporal gaps in observations. RAPID is a routing model based on the Muskingum method that is capable of estimating river streamflow over large scales with a relatively short computing time. This model only requires limited inputs: a reach-based river network, and lateral surface and subsurface flow into the rivers. The relatively simple model physics imply that RAPID simulations could be significantly improved by including a data assimilation capability. Here we present the early developments of such data assimilation approach into RAPID. Given the linear and matrix-based structure of the model, we chose to apply a direct Kalman filter, hence allowing for the preservation of high computational speed. We correct the simulated streamflows by assimilating streamflow observations and our early results demonstrate the feasibility of the approach. Additionally, the use of in situ gauges at continental scales motivates the application of our new data assimilation scheme to altimetry measurements from existing (e.g. EnviSat, Jason 2) and upcoming satellite missions (e.g. SWOT), and ultimately apply the scheme globally.

  8. Obesity and Dyslipidemia in South Asians

    2013-01-01

    Obesity and dyslipidemia are emerging as major public health challenges in South Asian countries. The prevalence of obesity is more in urban areas than rural, and women are more affected than men. Further, obesity in childhood and adolescents is rising rapidly. Obesity in South Asians has characteristic features: high prevalence of abdominal obesity, with more intra-abdominal and truncal subcutaneous adiposity than white Caucasians. In addition, there is greater accumulation of fat at “ectopic” sites, namely the liver and skeletal muscles. All these features lead to higher magnitude of insulin resistance, and its concomitant metabolic disorders (the metabolic syndrome) including atherogenic dyslipidemia. Because of the occurrence of type 2 diabetes, dyslipidemia and other cardiovascular morbidities at a lower range of body mass index (BMI) and waist circumference (WC), it is proposed that cut-offs for both measures of obesity should be lower (BMI 23–24.9 kg/m2 for overweight and ≥25 kg/m2 for obesity, WC ≥80 cm for women and ≥90 cm for men for abdominal obesity) for South Asians, and a consensus guideline for these revised measures has been developed for Asian Indians. Increasing obesity and dyslipidemia in South Asians is primarily driven by nutrition, lifestyle and demographic transitions, increasingly faulty diets and physical inactivity, in the background of genetic predisposition. Dietary guidelines for prevention of obesity and diabetes, and physical activity guidelines for Asian Indians are now available. Intervention programs with emphasis on improving knowledge, attitude and practices regarding healthy nutrition, physical activity and stress management need to be implemented. Evidence for successful intervention program for prevention of childhood obesity and for prevention of diabetes is available for Asian Indians, and could be applied to all South Asian countries with similar cultural and lifestyle profiles.

  11. Comparative Prospects of the New Development Bank and Asian Infrastructure Investment Bank

    Directory of Open Access Journals (Sweden)

    Andrei Shelepov

    2016-11-01

    Full Text Available In this article the author focuses on the recently established New Development Bank (NDB and Asian Infrastructure Investment Bank (AIIB. It identifies two factors of demand for this new model of multilateral development banks (MDBs, namely a lack of infrastructure financing and the aspirations of developing countries for a greater role in the global financial system. The author also compares the NDB and AIIB according to membership, management structure, distribution of capital and votes, and options for attracting capital in the financial market. Based on this comparison, he forecasts the banks’ credit portfolios growth until 2025. The author concludes that both institutions should accumulate and use the best practices of existing MDBs, improve their image to attract investors and actively engage in sharing expertise and co-financing projects with development institutions as well as commercial banks. By doing so, the volume of their operations could reach $40 billion per year in 10 years, which is close to the volume of infrastructure financing provided by major traditional banks, and could contribute substantially to addressing the financing needs of developing countries.

SWCNTs plays the role of a transducer in biological antigen/antibody reaction for the electrical signal while 1-pyrenebutanoic acid succinimidyl ester (1-PBSE) and ant-B. subtilis were performed as a chemical linker and an acceptor, respectively, for the adhesion of target microorganism in the developed biosensor. The detection range (10 2 -10 10  CFU/mL) and the detection limit (10 2  CFU/mL) of the developed biosensor were identified while the response time was 10 min. The amount of target B. subtilis was the highest in the specificity test of the developed biosensor, compared with the other tested microorganisms (Staphylococcus aureus, Flavobacterium psychrolimnae, and Aquabacterium commune). In addition, target B. subtilis detected by the developed biosensor was observed by scanning electron microscope (SEM) analysis. Copyright © 2017 Elsevier Ltd. All rights reserved.

    We report the results from cognitive interviews with Asian American patients and their caregivers. We interviewed seven caregivers and six patients who were all bilingual Asian Americans. The main goal of the cognitive interviews was to test a survey instrument developed for a study about perspectives of Asian American patients with advanced cancer who are facing decisions around end-of-life care. We were particularly interested to see whether items commonly used in White and Black populations are culturally meaningful and equivalent in Asian populations, primarily those of Chinese and Vietnamese ethnicity. Our exploration shows that understanding respondents' language proficiency, degree of acculturation, and cultural context of receiving, processing, and communicating information about medical care can help design questions that are appropriate for Asian American patients and caregivers, and therefore can help researchers obtain quality data about the care Asian American cancer patients receive. © The Author(s) 2016.

    Medical tourism is a new trend in medical service. It is booming not only in Asian countries but also in European and South American countries. Worldwide competition of medical service is expected in the future, and niche service will be a "trademark" for the promotion of global medicine. Niche service also functions for market segmentation. Niche services are usually surgical procedures. A study was carried out to compare different strategies for developing medical tourism in Asian countries. The role of a niche service is evaluated in the initiation and further development of medical tourism for individual countries. From this study, a general classification was proposed in terms of treatment procedures. It can be used as a useful guideline for additional studies in medical tourism. Niche service plays the following roles in the development of medical tourism: (1) It attracts attention in the mass media and helps in subsequent promotion of business, (2) it exerts pressure on the hospital, which must improve the quality of health care provided in treating foreign patients, especially the niche services, and (3) it is a tool for setting up the business model. E-Da Hospital is an example for developing medical tourism in Taiwan. A side effect is that niche service brings additional foreign patients, which will contribute to the benefit of the hospital, but this leaves less room for treating domestic patients. A niche service is a means of introduction for entry into the market of medical tourism. How to create a successful story is important for the development of a niche service. When a good reputation has been established, the information provided on the Internet can last for a long time and can spread internationally to form a distinguished mark for further development. Niche services can be classified into 3 categories: (1) Low-risk procedures with large price differences and long stay after retirement; (2) high-risk procedures with less of a price difference

    The high cost of software production is driving development organizations to adopt more automated design and analysis methods such as rapid prototyping, computer-aided software engineering (CASE) tools, and high-level code generators. Even developers of safety-critical software system have adopted many of these new methods while striving to achieve high levels Of quality and reliability. While these new methods may enhance productivity and quality in many cases, we examine some of the risks involved in the use of new methods in safety-critical contexts. We examine a case study involving the use of a CASE tool that automatically generates code from high-level system designs. We show that while high-level testing on the system structure is highly desirable, significant risks exist in the automatically generated code and in re-validating releases of the generated code after subsequent design changes. We identify these risks and suggest process improvements that retain the advantages of rapid, automated development methods within the quality and reliability contexts of safety-critical projects.

  16. Present state of research and development of atomic energy in five Asian countries

    Energy Technology Data Exchange (ETDEWEB)

    1981-01-01

    The survey group for Asian atomic energy cooperation was dispatched by the Japanese government, and toured Philippines, Indonesia, Malaysia, Thailand and Bangladesh from September 7 to 19, 1980. The present state of atomic energy development and the energy situation in respective countries were surveyed through the exchange of opinion and the inspection of related facilities. The Regional Cooperative Agreement for Research, Development and Training Related to Nuclear Science and Technology was concluded in June, 1972, and 12 countries have participated in it. It was impressive that respective countries have the peculiar energy policies corresponding to their objective conditions. They regard atomic energy as the important substitute energy for petroleum, but the fear about the safety of atomic energy and the movement against nuclear power generation have been growing considerably. The research and development on atomic energy are carried out very actively in respective countries, and the construction of large-scale research centers was commenced in Indonesia, Malaysia and Bangladesh. Research reactors have been operated in Philippines, Indonesia and Thailand since about 20 years ago, and the utilization of radioisotopes and radiation has been studied. The cooperation of Japan with these countries is far behind that of other advanced countries.

    Drawing on the current conceptualization of acculturation/enculturation as bilinear, multidimensional processes proceeding in interaction with surrounding contexts, this study examined ethnic identity development and cultural integration of 13 adolescents from East Asian immigrant families. Five domains emerged via the Consensual Qualitative Research method: ethnic/cultural identity and socialization; bicultural living; racial context-racism and stereotypes; family context-parental expectation; and peer context-friendship/dating. Overall, the participants experienced a cultural split and discontinuity between the 2 worlds of home and ethnic community versus school and society in general. They received strong ethnic socialization messages from family and ethnic community. Although most participants experienced hurtful racial discrimination, they used passive coping (e.g., dismiss, minimize, defend perpetrators). The model minority stereotype was prevalent and deeply engrained in many aspects of their lives including ethnic identity development, cultural socialization messages from mainstream society, discrimination experiences, and academic/occupational demands imposed by self, parents, peers, and society. Although they appreciated parents' high expectations of academic/occupational success, they felt pressured and desired to have space and independence. Friendship/dating patterns reflected ethnic identity development as well as contextual influence. Implications for research and practice are discussed.

    Full Text Available Aim: To study the postpartum conversion of gestational diabetes mellitus (GDM to different types of diabetes among Asian Indian women. Materials and Methods: Using data from electronic medical records, 418 women with GDM seen at a tertiary diabetes care center for diabetes in Chennai in South India between 1991 and 2014 were evaluated for development of diabetes postpartum. Results: Of the 418 GDM women followed up postpartum, 388 progressed to diabetes. Of these 359 (92.5% developed type 2 diabetes (T2DM and 29 women (7.5% developed type 1 diabetes (T1DM. The median time to development of T1DM was 2 years (interquartile range 2 [IQR] while for T2DM it was 5 years (IQR 6. Women who developed T1DM had significantly lower mean body mass index (BMI (20.4 ± 2.8 vs. 27.5 ± 4.4 kg/m 2 , P = 0.001, and higher fasting plasma glucose (222 ± 105 vs. 165 ± 62 mg/dl P = 0.008 and glycated hemoglobin levels (10.2 ± 2.7 vs. 8.5 ± 2.1% P < 0.001 compared to those who developed T2DM. Glutamic acid decarboxylase (GAD autoantibodies were present in 24/29 (82.7% of women who developed T1DM. Conclusion: A small but significant proportion of women with GDM progress to T1DM postpartum. Measurement of GAD antibodies in leaner women with more severe diabetes could help to identify women who are likely to develop T1DM and thus prevent their presentation with acute hyperglycemic emergencies after delivery.

    The management of municipal solid waste (MSW) is one of the main costs incurred by local authorities in developing countries. According to some estimates, these costs can account for up to 50% of city government budgets. It is therefore of importance that policymakers, urban planners and practitioners have an adequate understanding of what these costs consist of, from collection to final waste disposal. This article focuses on a specific stage of the MSW value chain, the treatment of waste, and it aims to identify cost patterns associated with the implementation and operation of waste treatment approaches in developing Asian countries. An analysis of the capital (CAPEX) and operational expenditures (OPEX) of a number of facilities located in countries of the region was conducted based on a database gathering nearly 100 projects and which served as basis for assessing four technology categories: composting, anaerobic digestion (AD), thermal treatment, and the production of refuse-derived fuel (RDF). Among these, it was found that the least costly to invest, asa function of the capacity to process waste, are composting facilities, with an average CAPEX per ton of 21,493 USD 2015 /ton. Conversely, at the upper end featured incineration plants, with an average CAPEX of 81,880 USD 2015 /ton, with this treatment approach ranking by and large as the most capital intensive of the four categories assessed. OPEX figures of the plants, normalized and analyzed in the form of OPEX/ton, were also found to be higher for incineration than for biological treatment methods, although on this component differences amongst the technology groups were less pronounced than those observed for CAPEX. While the results indicated the existence of distinct cost implications for available treatment approaches in the developing Asian context, the analysis also underscored the importance of understanding the local context asa means to properly identify the cost structure of each specific plant

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

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

    Energy Technology Data Exchange (ETDEWEB)

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

    2004-01-01

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

    In recent years, many disasters have been occured by influence of meteorological change in Japan. So, it becomes more important to inform rapid weather change caused by cumulus which brings concentrated heavy rain/hail, wind gust, lightning in a short period. These severe events should inclease in the future by global warming. Therefore we are developping the alert system for Rapidly Developing Cumulus Area (RDCA) detection using Japanese new satellite. At July 2015, Japan Meteorological Agency started operation of new geostationary meteorological satellite "Himawari-8". This satellite has optical imager named Advanced Himawari Imager (AHI). It can observe Japan area every 2.5 minutes. The frequently infrared image with high resolution (2km) is the key of our alert system. We took some special functions in the algorithm of this system. One of the points is cloud location which shifts to north from true location around Japan by viewing angle from the satellite above the equator. We moved clouds to the correct position using geometric correction method according to its height and latitude. This algorithm also follows a movement of cloud every 2.5 minutes during several observations. It derives the information about degree of the development of cumulus. The prototype system gives the alert before 30 to 60 minutes in advance to the first lightning in typical cumulus case. However, we understand that there are some difficult cases to alert. For example, winter low cloud over the Japan Sea which brings a winter lightning, and tornado (although it is not cumulus). Now, we are adjusting some parameters of the algorithm. In the near future, our algorithm will be used in weather information delivery service to the customer.

    Over the last 4 decades, China has undergone major economic development, resulting in considerable impacts on its wildlife populations and habitats. It is essential to quantify the conflict between development and conservation to assist with policy-making because forestry policies and market trends affected indirectly the distribution of Asian elephants. Here, we mapped the historical distribution of elephants versus human land use. Elephant distributions appear to occur in unbroken natural forests only. However, over the 40-year period, the distribution ranges have become smaller and fragmented, with natural forest area also declining by 16%. The monoculture of cash trees is encroaching on natural forests. Over the past 10 years, rubber plantations have become concentrated in the south, with extensive natural forests and scattered rubber farms being converted to tea plantations, due to changes in governmental policies and product prices. Through mapping the spatial changes in the distribution of rubber and tea plantations, our study is expected to help local managers to incorporate the needs of endangered elephants through creating space when planning plantations, especially in Xishuangbanna and the south part of Pu'er. In conclusion, restoring elephant habitat and establishing ecological corridors are critical for the survival of elephants in this region.

  5. Managing air quality in a rapidly developing nation: China

    Fang, Ming; Chan, Chak K.; Yao, Xiaohong

    As the world gets ready to begin the second decade of the twenty-first century, global climate change has been recognized as a real threat to civilization as we know it. The rapid and successful economic growth of developing nations, particularly China and India, is contributing to climate change. The route to initial economic success in China followed that of the developed nations through the development of industries. Unfortunately, China's environmental protection efforts have not been the same as in developed countries because China is vastly different culturally, socially, economically and, especially, politically from developed nations. When China started to deal with environmental concerns in the late 1970s, it took advantage of the experiences of other countries in establishing environmental standards and regulations, but it did not have a model to follow when it came to implementing these standards and regulations because of the abovementioned differences. Economically, China is transitioning from an agricultural base into an industrial base; however, even now, 60% of the population remains farmers. China has been and still is heavily dependent upon coal for energy, resulting in serious atmospheric particulate pollution. While growing efforts have been expended on the environment, at this juncture of its economic development, China would be well served to revisit the traditional "develop first and clean up later" approach and to find a balance between development and protecting the environment. Against this backdrop, a reflective look of the effort to manage air quality from 1949-2008 (with an emphasis on the past 30 years) in China is presented in this paper. The environmental component of the 2008 Olympic Games is examined as a special example to illustrate the current measures being used to improve air quality in China.

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

    2010-01-01

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

    1995-01-01

    During the last year, high level applications at CEBAF were written using the Tcl/Tk scripting language. This language is rapidly gaining in popularity, in part due to ease of constructing programs with X11 graphical user interfaces, and in part to ease of adding compiled user code for specialized purposes. Extensions to the language provide object oriented programming, which was used to develop a hierarchy of classes relevant for high level accelerator control. We describe basic language features, some 3rd party add-on packages, and local additions to the toolbox. Next we describe features of the accelerator object hierarchy, and finally describe applications written using this toolbox such as the ModelServer prototype, Slow Orbit and Energy Lock, the Linac Energy Management System, and other applications

    2012-05-01

    This paper presents several case studies of rapidly implemented, audience-specific applications for whole building energy modeling and standards analysis. By tailoring each application to the audience and the task at hand, the required learning curve for new users was greatly reduced. Each case study used OpenStudio, the U.S. Department of Energy's middleware software development kit (SDK). OpenStudio provides an easy interface to the EnergyPlus whole building simulation engine, while extending its capability and providing higher-level functionality such as software interoperability, standards, analysis, and optimization. Each case study is unique in the technology employed to interface with OpenStudio as well as the methods used for user interaction and data presentation. Four case studies are presented.

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

The concluding session had a panel discussion on possible future collaboration involving participants from different countries. The present report gives summary of each presentation. (author)

  12. Developing rapid methods for analyzing upland riparian functions and values.

    Science.gov (United States)

    Hruby, Thomas

    2009-06-01

    Regulators protecting riparian areas need to understand the integrity, health, beneficial uses, functions, and values of this resource. Up to now most methods providing information about riparian areas are based on analyzing condition or integrity. These methods, however, provide little information about functions and values. Different methods are needed that specifically address this aspect of riparian areas. In addition to information on functions and values, regulators have very specific needs that include: an analysis at the site scale, low cost, usability, and inclusion of policy interpretations. To meet these needs a rapid method has been developed that uses a multi-criteria decision matrix to categorize riparian areas in Washington State, USA. Indicators are used to identify the potential of the site to provide a function, the potential of the landscape to support the function, and the value the function provides to society. To meet legal needs fixed boundaries for assessment units are established based on geomorphology, the distance from "Ordinary High Water Mark" and different categories of land uses. Assessment units are first classified based on ecoregions, geomorphic characteristics, and land uses. This simplifies the data that need to be collected at a site, but it requires developing and calibrating a separate model for each "class." The approach to developing methods is adaptable to other locations as its basic structure is not dependent on local conditions.

  13. The Korean Peninsula Energy Development Organization : implications for Northeast Asian regional security co-operation?

    International Nuclear Information System (INIS)

    Snyder, S.

    2000-01-01

    This paper identifies opportunities for co-operation on regional development and security in the North Pacific region. The Korean Peninsula Energy Development Organization (KEDO) was created in 1993 during bilateral negotiations between the United States and the Democratic People's Republic of Korea (US-DPRK) over North Korea's alleged nuclear weapons program. The negotiations resulted in an agreement to freeze North Korea's known nuclear weapons program in return for the construction of two proliferation-resistant 100 MWe light water reactors (LWR) in North Korea, and the provision of 500,000 tons of heavy fuel oil per year until the completion of the LWR construction as compensation for lost energy production capacity resulting from the shutting down of North Korea's nuclear reactors. The author described the activities of KEDO and examined its internal dynamics. The unique circumstances that produced the Agreed Framework and KEDO in response to a major international crisis of the nuclear program in the DPRK were also highlighted along with the US-DPRK bilateral agreement and the multilateral institution involving the United States, South Korea, Japan and the European Union. Financial support from Australia and Canada was discussed along with the mechanism for engaging North Korea in regularized interaction and technical cooperation. It was concluded that KEDO's record of successes and failures is mixed. The energy security issue has been identified as an area that could result in conflict among Northeast Asian countries which are increasingly dependent on oil supplies from the Middle East. In response, numerous multilateral financing mechanisms have been developed to promote joint business opportunities that exploit natural gas resources in the Russian Far East to address Japanese, Korean and Chinese energy needs. 35 refs

RAP does two kinds of computing, "controls" and "general", addressed in sections 2 and 3 of this document For general computing, efficient system administration requires cooperation in using a common environment There is a much stronger need to define - and adhere to - a commonly agreed set of styles (or rules) in developing controls software. Right now, these rules have been set "de facto". Future improvements to the controls environment, particularly in response to the opinions of users, depends on broad knowledge of what the rules are. There are environmental issues that are basic to both controls and general computing, and that are so fundamental that they are (almost) unarguable. They are described immediately below, in the next section.

    This research consists of four studies on the initial reliability and validity of the Internalization of Asian American Stereotypes Scale (IAASS), a self-report instrument that measures the degree Asian Americans have internalized racial stereotypes about their own group. The results from the exploratory and confirmatory factor analyses support a stable four-factor structure of the IAASS: Difficulties with English Language Communication, Pursuit of Prestigious Careers, Emotional Reservation, and Expected Academic Success. Evidence for concurrent and discriminant validity is presented. High internal-consistency and test-retest reliability estimates are reported. A discussion of how this scale can contribute to research and practice regarding internalized stereotyping among Asian Americans is provided.

    To investigate the influence of eyelid shape on tear film quality, ocular surface characteristics and dry eye symptomatology by comparing Asian and Caucasian populations. Seventy-four age-matched participants were recruited in a cross-sectional study. Participants were classified into Asian single lid (ASL), Asian double lid (ADL), and Caucasian double lid (CDL) groups. Dry eye symptomatology, ocular surface characteristics, and tear film quality were evaluated in a single clinical session. Meibomian gland dropout was significantly greater in both the ASL and ADL groups than in the CDL group (all Pdry eye symptomatology between the three groups (all P>.05).

    Hepatitis B infection is 5 to 12 times more common among Asian Americans than in the general US population and is the leading cause of liver disease and liver cancer among Asians. The purpose of this article is to describe the step-by-step approach that we followed in community-based participatory research projects in 4 Asian American groups, conducted from 2006 through 2011 in California and Washington state to develop theoretically based and culturally appropriate interventions to promote hepatitis B testing. We provide examples to illustrate how intervention messages addressing identical theoretical constructs of the Health Behavior Framework were modified to be culturally appropriate for each community. Intervention approaches included mass media in the Vietnamese community, small-group educational sessions at churches in the Korean community, and home visits by lay health workers in the Hmong and Cambodian communities. Use of the Health Behavior Framework allowed a systematic approach to intervention development across populations, resulting in 4 different culturally appropriate interventions that addressed the same set of theoretical constructs. The development of theory-based health promotion interventions for different populations will advance our understanding of which constructs are critical to modify specific health behaviors.

    The objective of this project is to develop a transformational RApid Freeform sheet metal Forming Technology (RAFFT) in an industrial environment, which has the potential to increase manufacturing energy efficiency up to ten times, at a fraction of the cost of conventional technologies. The RAFFT technology is a flexible and energy-efficient process that eliminates the need for having geometry-specific forming dies. The innovation lies in the idea of using the energy resource at the local deformation area which provides greater formability, process control, and process flexibility relative to traditional methods. Double-Sided Incremental Forming (DSIF), the core technology in RAFFT, is a new concept for sheet metal forming. A blank sheet is clamped around its periphery and gradually deformed into a complex 3D freeform part by two strategically aligned stylus-type tools that follow a pre-described toolpath. The two tools, one on each side of the blank, can form a part with sharp features for both concave and convex shapes. Since deformation happens locally, the forming force at any instant is significantly decreased when compared to traditional methods. The key advantages of DSIF are its high process flexibility, high energy-efficiency, low capital investment, and the elimination of the need for massive amounts of die casting and machining. Additionally, the enhanced formability and process flexibility of DSIF can open up design spaces and result in greater weight savings.

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

    Abstract Yayasan Putra Asih Malida in library data processing both in data processing member, book loaning, returning book until making report still using manual method and still using paper media to recording existing data in library. This will certainly slow down the process. On the other hand, students also find it difficult to find a book to read because they do not know where the storage is. To solve the problem it is necessary to create a library information system design that can handle the data processing library so that the process runs efficiently and effectively. In addition to saving expenses to buy paper, this system can also make old archives stored neatly than to be stored in a closet or Warehouse. In the design of information systems libraries based on this wab, the authors use Rapid Application Development (RAD, Netbeans 8.1 application as a script-making software and Xampp 1.7.3 as a software-based database creation MYSQL. The results of this information system design can provide ease of the officers in processing data related to the processing of libraries and can simplify and accelerate and can save time in making reports, and data can be stored safely because it is using the database so that officers do not have to worry about the loss data.   Keywords: System, Information, Library, Web, RAD

    Full Text Available Background: Early detection of dementia aims to improve treatment outcomes. However, poor perception and understanding of dementia are significant barriers. We aim to investigate the public’s perception of dementia and identify variables associated with the different profiles of public perception. Methods: A custom-designed questionnaire was used to assess laypersons’ knowledge and perception of dementia during a health fair at a public hospital in Singapore, a developed Asian nation. Out of a sample of 370 subjects, 32 declined to participate (response rate = 91.4%. Latent class analysis (LCA was used to identify meaningful subgroups of subjects from significant associations with multiple indicators of dementia awareness. Multinomial logistic regression was performed exploring variables associated with each of the subgroups derived from LCA. Results: The majority of the study participants were female (66.9%, 65 years or older (71.1%, and ethnic Chinese (88.1%. LCA classified the study participants into 3 subgroups: Class 1 (good knowledge, good attitude, Class 2 (good knowledge, poor attitude, and Class 3 (poor knowledge, poor attitude, in proportions of 14.28, 63.83, and 21.88%, respectively. Compared to other classes, participants with good knowledge and good attitude towards dementia (Class 1 were more likely to know someone with dementia and understand the effects of the disease, be married, live in private housing, receive higher monthly income, and not profess belief in Buddhism, Taoism, or Hinduism. Conclusion: Our results show that the public in Singapore may not be ready for screening initiatives and early dementia diagnosis. Education efforts should be targeted at lower socioeconomic groups, singles, and those of certain oriental religions.

    Full Text Available The Asian citrus psyllid Diaphorina citri Kuwayama (Hemiptera: Liviidae is a serious pest worldwide, transmitting Candidatus Liberibacter spp. (Alphaproteobacteria, the causative agents of a devastating citrus disease known as huanglongbing or greening disease. In a symbiotic organ called the bacteriome, D. citri possesses an organelle-like defensive symbiont, Candidatus Profftella armatura (Betaproteobacteria, and a nutritional symbiont, Ca. Carsonella ruddii (Gammaproteobacteria. Drastically reduced symbiont genomes and metabolic complementarity among the symbionts and D. citri indicate their mutually indispensable association. Moreover, horizontal gene transfer between the Profftella and Liberibacter lineages suggests ecological and evolutionary interactions between the bacteriome symbiont and the HLB pathogen. Using fluorescence in situ hybridization, we examined the behavior of Profftella and Carsonella during transovarial transmission and the development of D. citri. In the bacteriomes of sexually-mature female adults, symbionts transformed from an extremely elongated tubular form into spherical or short-rod forms, which migrated toward the ovary. The symbionts then formed mosaic masses, which entered at the posterior pole of the vitellogenic oocytes. After anatrepsis, Carsonella and Profftella migrated to the central and peripheral parts of the mass, respectively. Following the appearance of host nuclei, the mass cellularized, segregating Carsonella and Profftella in the central syncytium and peripheral uninucleate bacteriocytes, respectively. Subsequently, the uninucleate bacteriocytes harboring Profftella assembled at the posterior pole, while the syncytium, containing Carsonella, sat on the anterior side facing the germ band initiating katatrepsis. During dorsal closure, the syncytium was divided into uninuclear bacteriocytes, which surrounded the mass of bacteriocytes containing Profftella. Once fully surrounded, the bacteriocyte mass

    The status of nitrate (NO 3 - ), nitrite (NO 2 - ) and ammonium (NH 4 + ) contamination in the water systems, and the mechanisms controlling their sources, pathways, and distributions were investigated for the Southeast Asian cities of Metro Manila, Bangkok, and Jakarta. GIS-based monitoring and dual isotope approach (nitrate δ 15 N and δ 18 O) suggested that human waste via severe sewer leakage was the major source of nutrient contaminants in Metro Manila and Jakarta urban areas. Furthermore, the characteristics of the nutrient contamination differed depending on the agricultural land use pattern in the suburban areas: high nitrate contamination was observed in Jakarta (dry fields), and relatively lower nutrients consisting mainly of ammonium were detected in Bangkok (paddy fields). The exponential increase in NO 3 - -δ 15 N along with the NO 3 - reduction and clear δ 18 O/δ 15 N slopes of NO 3 - (∼ 0.5) indicated the occurrence of denitrification. An anoxic subsurface system associated with the natural geological setting (e.g., the old tidal plain at Bangkok) and artificial pavement coverage served to buffer NO 3 - contamination via active denitrification and reduced nitrification. Our results showed that NO 3 - and NH 4 + contamination of the aquifers in Metro Manila, Bangkok, and Jakarta was not excessive, suggesting low risk of drinking groundwater to human health, at present. However, the increased nitrogen load and increased per capita gross domestic product (GDP) in these developing cities may increase this contamination in the very near future. Continuous monitoring and management of the groundwater system is needed to minimize groundwater pollution in these areas, and this information should be shared among adjacent countries with similar geographic and cultural settings

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

    A rapid increase in the economy, population, industrialization, and urbanization of Asian countries has driven the fast development of their meat industries over recent decades. This consistent increase in meat production and consumption in Asia has been the major cause for the development of the global meat industry. Meat production methods and consumption are very diverse across different regions and countries in Asia, and thus, it is impossible to cover the technological demands of all Asian countries in this review. Here, we have mainly highlighted the differences in meat production methods and consumption in Asia during recent decades and the meat technology demands of three east Asian countries, namely China, Korea, and Japan, and one south Asian country, India. A brief introduction of the meat industry, in particular the production and consumption trend in these countries, is provided in this article. The technology demands for fresh and processed meat products are then reviewed. Copyright © 2017. Published by Elsevier Ltd.

    Full Text Available The ability to respond to adverse environments effectively along with the ability to reproduce are sine qua non conditions for all sustainable cellular forms of life. Given the availability of an appropriate sensing modality, the ubiquity and immediacy of the stress response could form the basis for a new approach for rapid biological testing. We have found that measuring the dielectric permittivity of a cellular suspension, an easily measurable electronic property, is an effective way to monitor the response of bacterial cells to adverse conditions continuously. The dielectric permittivity of susceptible and resistant strains of Escherichia coli and Staphylococcus aureus, treated with gentamicin and vancomycin, were measured directly using differential impedance sensing methods and expressed as the Normalized Impedance Response (NIR. These same strains were also heat-shocked and chemically stressed with Triton X-100 or H(2O(2. The NIR profiles obtained for antibiotic-treated susceptible organisms showed a strong and continuous decrease in value. In addition, the intensity of the NIR value decrease for susceptible cells varied in proportion to the amount of antibiotic added. Qualitatively similar profiles were found for the chemically treated and heat-shocked bacteria. In contrast, antibiotic-resistant cells showed no change in the NIR values in the presence of the drug to which it is resistant. The data presented here show that changes in the dielectric permittivity of a cell suspension are directly correlated with the development of a stress response as well as bacterial recovery from stressful conditions. The availability of a practical sensing modality capable of monitoring changes in the dielectric properties of stressed cells could have wide applications in areas ranging from the detection of bacterial infections in clinical specimens to antibiotic susceptibility testing and drug discovery.

    ICP-MS has begun to spread in the field of individual monitoring for internal exposure as a very effective machine for uranium analysis. Although the ICP-MS has very high sensitivity, it requires longer time than conventional analysis, such as fluorescence analysis, because it is necessary to remove matrix from a urine sample sufficiently. To shorten time required for the urine bioassay by ICP-MS, a rapid uranium analysis method using the ICP-MS connected with a flow injection system was developed. Since this method does not involve chemical separation steps, the time required is equivalent to the conventional analysis. A measurement test was carried out using 10 urine solutions prepared from a urine sample. Required volume of urine solution is 5 ml. Main chemical treatment is only the digestion with 5 ml of nitric acid using a microwave oven to decompose organic matter and to dissolve suspended or precipitated matter. The microwave oven can digest 10 samples at once within an hour. Volume of digested sample solution was adjusted to 10 ml. The prepared sample solutions were directly introduced to the ICP-MS without any chemical separation procedure. The ICP-MS was connected with a flow injection system and an auto sampler. The flow injection system can minimize the matrix effects caused from salt dissolved in high matrix solution, such as non chemical separated urine sample, because it can introduce micro volume of sample solution into the ICP-MS. The ICP-MS detected uranium within 2 min/sample using the auto sampler. The 10 solutions prepared from a urine sample showed an average of 7.5 ng/l of uranium concentration in urine with 10 % standard deviation. A detection limit is about 1 ng/l. The total time required was less than 4 hours for 10 sample analysis. In the series of measurement, any memory effect was not observed. The present analysis method using the ICP-MS equipped with the flow injection system demonstrated that the shortening of time required on high

Black-Right-Pointing-Pointer Compared changes in testis-related transcripts with testis germ cell distribution. Black-Right-Pointing-Pointer Our study on endosulfan endorse its prompt and complete phase-out/ban. - Abstract: Endosulfan and flutamide, a widely used pesticide and a prostate cancer/infertility drug, respectively, have an increased risk of causing endocrine disruption if they reach water bodies. Though many studies are available on neurotoxicity/bioaccumulation of endosulfan and receptor antagonism of flutamide, only little is known about their impact on testicular steroidogenesis at molecular level. Sex steroids play an important role in sex differentiation of lower vertebrates including fishes. Hence, a small change in their levels caused by endocrine disruptors affects the gonadal development of aquatic vertebrates significantly. The aim of this study was to evaluate the effects of endosulfan and flutamide on testis-related transcription factor and steroidogenic enzyme genes with a comparison on the levels of androgens during critical period of catfish testicular development. We also analyzed the correlation between the above-mentioned genes and catfish gonadotropin-releasing hormone (cfGnRH)-tryptophan hydroxylase2 (tph2). The Asian catfish, Clarias batrachus males at 50 days post hatch (dph) were exposed to very low dose of endosulfan (2.5 {mu}g/L) and flutamide (33 {mu}g/L), alone and in combination for 50 days. The doses used in this study were far less than those used in the previous studies of flutamide and reported levels of endosulfan in surface water and sediments. Sampling was done at end of the treatments (100

    The motesanib phase III MONET1 study failed to show improvement in overall survival (OS) in non-small cell lung cancer, but a subpopulation of Asian patients had a favorable outcome. We performed exploratory modeling and simulations based on MONET1 data to support further development of motesanib in Asian patients. A model-based estimate of time to tumor growth was the best of tested tumor size response metrics in a multivariate OS model (P Simulations indicated that a phase III study in 500 Asian patients would exceed 80% power to confirm superior efficacy of motesanib combination therapy (expected HR: 0.74), suggesting that motesanib combination therapy may benefit Asian patients.

    Based on the recognition that international development of nuclear industry was important by a viewpoint of international cooperation to neighboring Asian area and also it was the trump that defeated a feeling of domestic confinement, the Japan Atomic Industrial Forum (JAIF) founded Nuclear energy international development gathering' in November 2004. On that occasion our magazine (March, 2005 issue) featured 'prospects and problem of the international development of nuclear energy use'. Slightly for half a year afterwards this nuclear energy international development has been rapidly deepened and become a close-up as a policy of an important strategy of the field of nuclear energy that the government and the private sector were united to make. Therefore the nuclear energy international development was secondly featured from multidirectional points of view such as a background of nuclear energy international development, composition of international nuclear energy business, a main strategy of three makers, approach of finance / a business firm.

    2012-01-01

    Background Plasma total carotenoids can be used as an indicator of risk of chronic disease. Laboratory analysis of individual carotenoids by high performance liquid chromatography (HPLC) is time consuming, expensive, and not amenable to use beyond a research laboratory. The aim of this research is to establish a rapid, simple, and inexpensive spectrophotometric assay of plasma total carotenoids that has a very strong correlation with HPLC carotenoid profile analysis. Results Plasma total carotenoids from 29 volunteers ranged in concentration from 1.2 to 7.4 μM, as analyzed by HPLC. A linear correlation was found between the absorbance at 448 nm of an alcohol / heptane extract of the plasma and plasma total carotenoids analyzed by HPLC, with a Pearson correlation coefficient of 0.989. The average coefficient of variation for the spectrophotometric assay was 6.5% for the plasma samples. The limit of detection was about 0.3 μM and was linear up to about 34 μM without dilution. Correlations between the integrals of the absorption spectra in the range of carotenoid absorption and total plasma carotenoid concentration gave similar results to the absorbance correlation. Spectrophotometric assay results also agreed with the calculated expected absorbance based on published extinction coefficients for the individual carotenoids, with a Pearson correlation coefficient of 0.988. Conclusion The spectrophotometric assay of total carotenoids strongly correlated with HPLC analysis of carotenoids of the same plasma samples and expected absorbance values based on extinction coefficients. This rapid, simple, inexpensive assay, when coupled with the carotenoid health index, may be useful for nutrition intervention studies, population cohort studies, and public health interventions.

    Full Text Available The impacts of various scenarios of a gradual snow and glaciers developing over the Tibetan Plateau on climate change in Afro-Asian monsoon region and other regions during the Holocene (9 kyr BP–0 kyr BP are studied by using the Earth system model of intermediate complexity, CLIMBER-2. The simulations show that the imposed snow and glaciers over the Tibetan Plateau in the mid-Holocene induce global summer temperature decreases over most of Eurasia but in the Southern Asia temperature response is opposite. With the imposed snow and glaciers, summer precipitation decreases strongly in North Africa and South Asia as well as northeastern China, while it increases in Southeast Asia and the Mediterranean. For the whole period of Holocene (9 kyr BP–0 kyr BP, the response of vegetation cover to the imposed snow and glaciers cover over the Tibetan Plateau is not synchronous in South Asia and in North Africa, showing an earlier and a more rapid decrease in vegetation cover in North Africa from 9 kyr BP to 6 kyr BP while it has only minor influence on that in South Asia until 5 kyr BP. The precipitation decreases rapidly in North Africa and South Asia while it decreases slowly or unchanged during 6 kyr BP to 0 kyr BP with imposed snow and glacier cover over the Tibetan Plateau. The different scenarios of snow and glacier developing over the Tibetan Plateau would result in differences in variation of temperature, precipitation and vegetation cover in North Africa, South Asia and Southeast Asia. The model results suggest that the development of snow and ice cover over Tibetan Plateau represents an additional important climate feedback, which amplify orbital forcing and produces a significant synergy with the positive vegetation feedback.

    Confirming Ebola virus disease (EVD), a deadly infectious disease, requires real-time RT-PCR, which takes up to a few hours to yield results. Therefore, a rapid diagnostic assay is imperative for EVD diagnosis. A rapid nucleic acid test based on recombinase polymerase amplification (EBOV-RPA) was developed to specifically detect the 2014 outbreak strains. The EBOV-RPA assay was evaluated by testing samples from suspected EVD patients in parallel with RT-PCR. An EBOV-RPA, which could be completed in 20 min, was successfully developed. Of 271 patients who tested positive for Ebola virus by RT-PCR, 264 (sensitivity: 97%, 95% CI: 95.5-99.3%) were positive by EBOV-RPA; 101 of 104 patients (specificity: 97%, 95% CI: 93.9-100%) who tested negative by RT-PCR were also negative by EBOV-RPA. The sensitivity values for samples with a Ct value of RPA had significantly high Ct values. Results of external quality assessment samples with EBOV-RPA were 100%, consistent with those of RT-PCR. The EBOV-RPA assay showed 97% sensitivity and 97% specificity for all EVD samples tested, making it a rapid and sensitive test for EVD diagnosis.

    Rheumatologic and public health services of Central Asia's republics have suffered hugely as a result of social and economic declines following the dissolution of the Union of Soviet Socialist Republics (USSR) and transition of these republics to market economies. Between 1990 and 2000 there was a mass outflow of highly skilled rheumatologists and teachers and researchers in rheumatology to countries abroad, leading to significant deprivation of rheumatological service in Central Asian countries. During this time, there was continued growth of various rheumatic diseases (RDs) including rheumatic fever, and musculoskeletal and connective tissue disorders. The medical and social burden of RDs imposed on society was strongly underestimated until recent times. There is an urgent need to define the epidemiology of RDs and their impact on the quality of life of people afflicted by these conditions, and to improve the diagnostics and treatment of these conditions.

    Increasing efforts are being made globally on capacity building. North-south research partnerships have contributed significantly to enhancing the research capacity in low- and middle-income countries (LMICs) over the past few decades; however, a lack of skilled researchers to inform health policy development persists, particularly in LMICs. The EU FP7 funded African/Asian Regional Capacity Development (ARCADE) projects were multi-partner consortia aimed to develop a new generation of highly trained researchers from universities across the globe, focusing on global health-related subjects: health systems and services research and research on social determinants of health. This article aims to outline the successes, challenges and lessons learned from the life course of the projects, focusing on the key outputs and experiences of developing and implementing these two projects together with sub-Saharan African, Asian and European institution partners. Sixteen participants from 12 partner institutions were interviewed. The data were analysed using thematic content analysis, which resulted in four themes and three sub-categories. These data were complemented by a review of project reports. The results indicated that the ARCADE projects have been successful in developing and delivering courses, and have reached over 920 postgraduate students. Some partners thought the north-south and south-south partnerships that evolved during the project were the main achievement. However, others found there to be a 'north-south divide' in certain aspects. Challenges included technical constraints and quality assurance. Additionally, adapting new teaching and learning methods into current university systems was challenging, combined with not being able to award students with credits for their degrees. The ARCADE projects were introduced as an innovative and ambitious project idea, although not designed appropriately for all partner institutions. Some challenges were underestimated

    The future of mountain water resources in High Asia is of high interest to water managers, development organizations and policy makers given large populations downstream reliant on snow and ice sourced river flow. Together with historical and cultural divides among ex-Soviet republics, a lack of central water management following the Soviet break-up has led to water stress as trans-boundary waters weave through and along borders. New upstream hydropower development, a thirsty downstream agricultural sector and a shrinking Aral Sea has led to increasing tension in the region. Despite these pressures and in contrast to eastern High Asia's Himalayan basins (Ganges, Brahmaputra), little attention has been given to western High Asia draining the Pamir and Tien Shan ranges (Syr Darya and Amu Darya basins) to better understand the hydrology of this vast and remote area. Difficult access and challenging terrain exacerbate challenges to working in this remote mountain region. As part of the Contributions to High Asia Runoff from Ice and Snow (CHARIS) project, we asked how does river flow source water composition change over an alpine-to-plains domain of Kyrgyzstan's Naryn River in the Syr Darya basin? In addition, what may the future hold for river flow in Central Asia given the differing responses of snow and ice to climate changes? Utilizing a Rapid Hydrologic Assessment methodology including a suite of pre-field mapping techniques we collected in situ water chemistry data at targeted, remote mountain sites over 450km of the Naryn River over an elevation gradient from glacial headwaters to the lower lying areas - places where people, hydropower and agriculture utilize water. Chemical and isotope tracers were used to separate stream flow to understand relative dependency on melt waters as the river moves downstream from glaciers and snow covered areas. This case study demonstrates a technique to acquire field data over large scales in remote regions that facilitates

The prevalence rates of childhood overweight and obesity in Asian developing countries ranged from 5.1% to 19.9% with no specific trend in age or gender. Several significant but inconsistent statistical associations between dietary patterns and overweight/obesity in children and adolescents were found [high energy diet (OR: 1.80 95%CI 1.10 to 2.90, p0.05), low intake of fruit and vegetables (OR: 2.34 95%CI 1.04 to 5.24, p0.05; 0.70 95%CI 0.50 to 1.00, p>0.05), high meat consumption (RR: 2.40 95%CI 1.00 to 5.60, p0.05), eating out (OR: 12.0 95%CI 7.7 to 18.7, p0.05), fast food intake (OR: 1.50 95%CI 1.12 to 2.02, p0.05)]. The key limitation was the heterogeneity of studies in terms of measures of dietary patterns and obesity standards. The prevalence rates of childhood overweight and obesity in Asian developing countries ranged from 5.1% to 19.9% with no specific trend in age or gender. From the practice perspective, several significant yet inconsistent statistical associations between dietary patterns and childhood overweight/obesity in children and adolescents were found.This review highlights the need for clinicians to monitor the effects of dietary change on the weight and health status of children in Asian countries.There is a need for valid measures of dietary intake and use of standardised international cut-offs for overweight and obesity, and for future researchers to conduct prospective studies to determine the causal relationship between Asian children's dietary pattern and their weight status.

    The evolution of life history (pace of growth and reproduction) was crucial to ancient hominin adaptations. The study of dental development facilitates assessment of growth and development in fossil hominins with greater precision than other skeletal analyses. During tooth formation, biological rhythms manifest in enamel and dentine, creating a permanent record of growth rate and duration. Quantification of these internal and external incremental features yields developmental benchmarks, including ages at crown completion, tooth eruption, and root completion. Molar eruption is correlated with other aspects of life history. Recent evidence for developmental differences between modern humans and Neanderthals remains ambiguous. By measuring tooth formation in the entire dentition of a juvenile Neanderthal from Scladina, Belgium, we show that most teeth formed over a shorter time than in modern humans and that dental initiation and eruption were relatively advanced. By registering manifestations of stress across the dentition, we are able to present a precise chronology of Neanderthal dental development that differs from modern humans. At 8 years of age at death, this juvenile displays a degree of development comparable with modern human children who are several years older. We suggest that age at death in juvenile Neanderthals should not be assessed by comparison with modern human standards, particularly those derived from populations of European origin. Moreover, evidence from the Scladina juvenile and other similarly aged hominins suggests that a prolonged childhood and slow life history are unique to Homo sapiens.

    2012-01-01

    Full Text Available Low-level bytecode instrumentation techniques are widely used in many software-engineering tools for the Java Virtual Machine (JVM, that perform some form of dynamic program analysis, such as profilers or debuggers. While program manipulation at the bytecode level is very flexible, because the possible bytecode transformations are not restricted, tool development based on this technique is tedious and error-prone. As a promising alternative, the specification of bytecode instrumentation at a higher level using aspect-oriented programming (AOP can reduce tool development time and cost. Unfortunately, prevailing AOP frameworks lack some features that are essential for certain dynamic analyses. In this article, we focus on three common shortcomings in AOP frameworks with respect to the development of aspect-based tools - (1 the lack of mechanisms for passing data between woven advices in local variables, (2 the support for user-defined static analyses at weaving time, and (3 the absence of pointcuts at the level of individual basic blocks of code. We propose @J, an annotation-based AOP language and weaver that integrates support for these three features. The benefits of the proposed features are illustrated with concrete examples.

    Full text: ANSTO is undertaking the parallel development of instrument control and graphical experiment interface software for seven neutron beam instruments at OPAL. Each instrument poses several challenges for a common system solution, including custom detector interfaces, a range of motion and beamline optics schema, and a spectrum of online data reduction requirements. To provide a superior system with the least development effort, the computing team have adopted proven, configurable, server-based control software (SICS)1., a highly Integrated Scientific Experimental Environment (GumTree)2. and industry-standard database management systems. The resulting graphical interfaces allow operation in a familiar experiment domain, with monitoring of data and parameters independent of control system specifics. GumTree presents the experimenter with a consistent interface for experiment management, instrument control and data reduction tasks. The facility instrument scientists can easily reconfigure instruments and add ancillaries. The user community can expect a reduced learning curve for performing each experiment. GumTree can be installed anywhere for pre-experiment familiarisation, postprocessing of acquired data sets, and integration with third party analysis tools. Instrument scientists are seeing faster software development iterations and have a solid basis to prepare for the next suite of instruments. 1. SICS from PSI (lns00.psi.ch). 2.

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

    The Association of South East Asian Nations or ASEAN is a regional association of seven countries, namely Indonesia, Malaysia, Philippines, Singapore, Thailand, Brunei and Vietnam, located at the south eastern part of the Asian continent. Together with the East Asian States of Japan, China, Korea and Taiwan, this part of the world is experiencing rapid economic growth, especially in the last decade. Rapid industrialization has resulted in an increased demand for energy in the manufacturing and transport sectors, and also for infrastructure development. This has led to a significant increase in gaseous emissions and a corresponding increase in atmospheric acidity. Acid deposition study in the ASEAN countries began in the mid-70s when Malaysia first started her acid rain monitoring network in 1976. This was followed closely by Singapore and the other ASEAN countries in the 80s. By now all ASEAN countries have their own acid rain monitoring networks with a number of these countries extending the monitoring to dry deposition as well.

  8. Evolution of gliding in Southeast Asian geckos and other vertebrates is temporally congruent with dipterocarp forest development.

    2012-12-23

    Gliding morphologies occur in diverse vertebrate lineages in Southeast Asian rainforests, including three gecko genera, plus frogs, snakes, agamid lizards and squirrels. It has been hypothesized that repeated evolution of gliding is related to the dominance of Asian rainforest tree floras by dipterocarps. For dipterocarps to have influenced the evolution of gliding in Southeast Asian vertebrates, gliding lineages must have Eocene or later origins. However, divergence times are not known for most lineages. To investigate the temporal pattern of Asian gliding vertebrate evolution, we performed phylogenetic and molecular clock analyses. New sequence data for geckos incorporate exemplars of each gliding genus (Cosymbotus, Luperosaurus and Ptychozoon), whereas analyses of other vertebrate lineages use existing sequence data. Stem ages of most gliding vertebrates, including all geckos, cluster in the time period when dipterocarps came to dominate Asian tropical forests. These results demonstrate that a gliding/dipterocarp correlation is temporally viable, and caution against the assumption of early origins for apomorphic taxa.

  9. Development and selection of Asian-specific humeral implants based on statistical atlas: toward planning minimally invasive surgery.

    The commercial humeral implants based on the Western population are currently not entirely compatible with Asian patients, due to differences in bone size, shape and structure. Surgeons may have to compromise or use different implants that are less conforming, which may cause complications of as well as inconvenience to the implant position. The construction of Asian humerus atlases of different clusters has therefore been proposed to eradicate this problem and to facilitate planning minimally invasive surgical procedures [6,31]. According to the features of the atlases, new implants could be designed specifically for different patients. Furthermore, an automatic implant selection algorithm has been proposed as well in order to reduce the complications caused by implant and bone mismatch. Prior to the design of the implant, data clustering and extraction of the relevant features were carried out on the datasets of each gender. The fuzzy C-means clustering method is explored in this paper. Besides, two new schemes of implant selection procedures, namely the Procrustes analysis-based scheme and the group average distance-based scheme, were proposed to better search for the matching implants for new coming patients from the database. Both these two algorithms have not been used in this area, while they turn out to have excellent performance in implant selection. Additionally, algorithms to calculate the matching scores between various implants and the patient data are proposed in this paper to assist the implant selection procedure. The results obtained have indicated the feasibility of the proposed development and selection scheme. The 16 sets of male data were divided into two clusters with 8 and 8 subjects, respectively, and the 11 female datasets were also divided into two clusters with 5 and 6 subjects, respectively. Based on the features of each cluster, the implants designed by the proposed algorithm fit very well on their reference humeri and the proposed

    2016-10-01

    Full Text Available Introduction: Increasing efforts are being made globally on capacity building. North–south research partnerships have contributed significantly to enhancing the research capacity in low- and middle-income countries (LMICs over the past few decades; however, a lack of skilled researchers to inform health policy development persists, particularly in LMICs. The EU FP7 funded African/Asian Regional Capacity Development (ARCADE projects were multi-partner consortia aimed to develop a new generation of highly trained researchers from universities across the globe, focusing on global health-related subjects: health systems and services research and research on social determinants of health. This article aims to outline the successes, challenges and lessons learned from the life course of the projects, focusing on the key outputs and experiences of developing and implementing these two projects together with sub-Saharan African, Asian and European institution partners. Design: Sixteen participants from 12 partner institutions were interviewed. The data were analysed using thematic content analysis, which resulted in four themes and three sub-categories. These data were complemented by a review of project reports. Results: The results indicated that the ARCADE projects have been successful in developing and delivering courses, and have reached over 920 postgraduate students. Some partners thought the north–south and south–south partnerships that evolved during the project were the main achievement. However, others found there to be a ‘north–south divide’ in certain aspects. Challenges included technical constraints and quality assurance. Additionally, adapting new teaching and learning methods into current university systems was challenging, combined with not being able to award students with credits for their degrees. Conclusion: The ARCADE projects were introduced as an innovative and ambitious project idea, although not designed

    The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is an introduced pest in Mexico and a vector of huanglongbing, a lethal citrus disease. Estimations of the habitat distribution and population growth rates of D. citri are required to establish regional and areawide management strategies and can be used as a pest risk analysis tools. In this study, the habitat distribution of D. citri in Mexico was computed with MaxEnt, an inductive, machine-learning program that uses bioclimatic layers and point location data. Geographic distributions of development and population growth rates were determined by fitting a temperature-dependent, nonlinear model and projecting the rates over the target area, using the annual mean temperature as the predictor variable. The results showed that the most suitable regions for habitat of D. citri comprise the Gulf of Mexico states, Yucatán Peninsula, and areas scattered throughout the Pacific coastal states. Less suitable areas occurred in northern and central states. The most important predictor variables were related to temperature. Development and growth rates had a distribution wider than habitat, reaching some of the northern states of México. Habitat, development, and population growth rates were correlated to each other and with the citrus producing area. These relationships indicated that citrus producing states are within the most suitable regions for the occurrence, development, and population growth of D. citri, therefore increasing the risk of huanglongbing dispersion.

    2016-11-01

    Economic prosperity and increasing connectivity have made Asia an emerging centre of growth in health care, including in the field of urology. Large and varied patient populations, the availability of a trained workforce, the use of English as a common communication language, and overall low costs have contributed to this change. Rapid growth of regional urological associations and journals has fuelled the aspirations and abilities of Asian urologists to not only keep abreast of but often lead the change in urological disease management. Asian urology has immense potential to expand in areas in which it currently lags behind, the most important being research. The increasing ability to travel aids in developing networks for collaboration. However, Asian urologists will need to look at sustainable models of engagement and temper the need for short-term results if these opportunities are to reach their maximal potential.

    Full Text Available Huanglongbing (HLB causes considerable economic losses to citrus industries worldwide. Its management depends on controlling of the Asian citrus Psyllid (ACP, the vector of the bacterium, Candidatus Liberibacter asiaticus (CLas, the causal agent of HLB. Silencing genes by RNA interference (RNAi is a promising tool to explore gene functions as well as control pests. In the current study, abnormal wing disc (awd gene associated with wing development in insects is used to interfere with the flight of psyllids. Our study showed that transcription of awd is development-dependent and the highest level was found in the last instar (5(th of the nymphal stage. Micro-application (topical application of dsRNA to 5(th instar of nymphs caused significant nymphal mortality and adult wing-malformation. These adverse effects in ACP were positively correlated with the amounts of dsRNA used. A qRT-PCR analysis confirmed the dsRNA-mediated transcriptional down-regulation of the awd gene. Significant down-regulation was required to induce a wing-malformed phenotype. No effect was found when dsRNA-gfp was used, indicating the specific effect of dsRNA-awd. Our findings suggest a role for awd in ACP wing development and metamorphosis. awd could serve as a potential target for insect management either via direct application of dsRNA or by producing transgenic plants expressing dsRNA-awd. These strategies will help to mitigate HLB by controlling ACP.

    The Asian long-horned beetle (ALB), Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae: Lamiinae), is a wood-borer and polyphagous xylophage that is native to Asia. It infests and seriously harms healthy trees, and therefore is a cause for considerable environmental concern. The analysis of population genetic structure of ALB and sibling species Anoplophora nobilis (Ganglbauer) will not only help to clarify the relationship between environmental variables and mechanisms of speciation, but also will enhance our understanding of evolutionary processes. However, the known genetic markers, particularly microsatellites, are limited for this species. SSRLocator software was used to analyze the distribution and frequencies of genomic simple sequence repeat (SSR), to infer the basic characteristics of repeat motifs, and to design primers. We developed SSR loci of 2-6 repeated units, including 10,650 perfect SSRs, and found 140 types of repeat motifs. A total of 2621 SSR markers were discovered in ALB whole-genome shotgun sequences. 48 pairs of SSR primers were randomly chosen from 2621 SSR markers, and half of these 48 pairs were polymorphic containing 4 di-, 7 tri-, 2 tetra-, and 11-hexamer SSRs. Four populations test the effectiveness of the primers. These results suggest that our method for whole-genome SSR screening is feasible and efficient, and the SSR markers developed in this study are suitable for further population genetics studies of ALB. Moreover, they may also be useful for the development of SSRs for other Coleoptera.

    New-onset diabetes mellitus (NODM) after liver transplantation is a common complication with a potentially negative impact on patient outcome. To evaluate the incidence of NODM and its impact on Asian adult living donor liver transplant (LDLT) recipients, we investigated 369 adult LDLT cases in our institute. Preoperative diabetes mellitus (DM) was diagnosed in 38 (9 %) patients. NODM was observed in 128/331 (38 %) patients, 56 (44 %) with persistent NODM and 72 (56 %) with transient NODM. The mean interval between LDLT and the development of NODM was 0.6 ± 1.8 (range 0-1.4) months. Multivariate analyssis revealed that older age, being male and having a higher body mass index were independent risk factors among recipients for developing NODM, while hepatitis C virus infection was not a significant risk factor, and DM had no impact on patient outcome. Although the long-term effect of DM on outcome remains to be investigated, the presence of DM after liver transplant, whether it was NODM or preexisting DM, had no impact on LDLT recipients' outcomes in mid-term. © 2013 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

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

    Directory of Open Access Journals (Sweden)

    Yasuhiro Homma

    2014-01-01

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

  12. Development and Interpretation of New Sediment Rating Curve Considering the Effect of Vegetation Cover for Asian Basins

    Directory of Open Access Journals (Sweden)

    Jie Wang

    2013-01-01

    Full Text Available Suspended sediment concentration of a river can provide very important perspective on erosion or soil loss of one river basin ecosystem. The changes of land use and land cover, such as deforestation or afforestation, affect sediment yield process of a catchment through changing the hydrological cycle of the area. A sediment rating curve can describe the average relation between discharge and suspended sediment concentration for a certain location. However, the sediment load of a river is likely to be undersimulated from water discharge using least squares regression of log-transformed variables and the sediment rating curve does not consider temporal changes of vegetation cover. The Normalized Difference Vegetation Index (NDVI can well be used to analyze the status of the vegetation cover well. Thus long time monthly NDVI data was used to detect vegetation change in the past 19 years in this study. Then monthly suspended sediment concentration and discharge from 1988 to 2006 in Laichau station were used to develop one new sediment rating curve and were validated in other Asian basins. The new sediment model can describe the relationship among sediment yield, streamflow, and vegetation cover, which can be the basis for soil conservation and sustainable ecosystem management.

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

  15. A Review of Recent Developments in the Study of Regional Lithospheric Electrical Structure of the Asian Continent

    Science.gov (United States)

    Zhang, Letian

    2017-09-01

    The Asian continent was formed through the amalgamation of several major continental blocks that were formerly separated by the Paleo-Asian and Tethyan Oceans. During this process, the Asian continent underwent a long period of continental crustal growth and tectonic deformation, making it the largest and youngest continent on Earth. This paper presents a review of the application of geophysical electromagnetic methods, mainly the magnetotelluric (MT) method, in recent investigations of the diverse tectonic features across the Asian continent. The case studies cover the major continental blocks of Asia, the Central Asian orogenic system, the Tethyan orogenic system, as well as the western Pacific subduction system. In summary, most of the major continental blocks of Asia exhibit a three-layer structure with a resistive upper crust and upper mantle and a relatively conductive mid-lower crust. Large-scale conductors in the upper mantle were interpreted as an indication of lithospheric modification at the craton margins. The electrical structure of the Central Asian orogenic system is generally more resistive than the bordering continental blocks, whereas the Tethyan orogenic system displays more conductive, with pervasive conductors in the lower crust and upper mantle. The western Pacific subduction system shows increasing complexity in its electrical structure from its northern extent to its southern extent. In general, the following areas of the Asian continent have increasingly conductive lithospheric electrical structures, which correspond to a transition from the most stable areas to the most active tectonic areas of Asia: the major continental blocks, the accretionary Central Asian orogenic system, the collisional Tethyan orogenic system, and the western Pacific subduction system. As a key part of this review, a three-dimensional (3-D) model of the lithospheric electrical structure of a large portion of the Tibetan Plateau is presented and discussed in detail

    Feline leukemia virus (FeLV) causes a range of neoplastic and degenerative diseases in cats. To obtain a more sensitive and convenient diagnosis of the disease, we prepared monoclonal antibodies specific for the FeLV p27 to develop a rapid diagnostic test with enhanced sensitivity and specificity. Among these antibodies, we identified two clones (hybridomas 8F8B5 and 8G7D1) that specifically bound to FeLV and were very suitable for a diagnostic kit. The affinity constants for 8F8B5 and 8G7D1 were 0.35 × 10⁸ and 0.86 × 10⁸, respectively. To investigate the diagnostic abilities of the rapid kit using these antibodies, we performed several clinical studies. Assessment of analytical sensitivity revealed that the detection threshold of the rapid diagnostic test was 2 ng/mL for recombinant p27 and 12.5 × 10⁴ IU/mL for FeLV. When evaluating 252 cat sera samples, the kit was found to have a kappa value of 0.88 compared to polymerase chain reaction (PCR), indicating a significant correlation between data from the rapid diagnostic test and PCR. Sensitivity and specificity of the kit were 95.2% (20/21) and 98.5% (257/261), respectively. Our results demonstrated that the rapid diagnostic test would be a suitable diagnostic tool for the rapid detection of FeLV infection in cats.

    Full Text Available Background In developing countries, population estimates and assessments of progress towards the Millenium Development Goals are based increasingly on household surveys.  It is not recognised that they are inappropriate for obtaining information about the poorest of the poor..  This is because they, typically, omit by design: those not in households because they are homeless; those who are in institutions; and mobile, nomadic or pastoralist populations.  In addition, in practice, because they are difficult to reach, household surveys will typically under-represent: those in fragile, disjointed or multiple occupancy households; those in urban slums, and may omit certain areas of a country deemed to pose a security risk. Those six sub-groups constitute a pretty comprehensive ostensive definition of the ‘poorest of the poor’. Methods This paper documents these omissions in general, drawing on worldwide literature about the theory and practice fo implementing censuses and household surveys; and shows how substantial proportions are missing from both censuses and the sample frames of surveys. Results This paper suggests that between 300 and 350 million will effectively be missed worldwide from the sampling frames of such surveys and from most censuses.  The impact on the health MDGs is illustrated for the five republics of the former Soviet Union making up Central Asia: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan Conclusions It is impossible to assess progress towards or away from the MDGS in both the Central Asian Republics and worldwide.  It is urgent to find solutions to the problem of the ‘missing ‘ poor population sub-groups.

  1. Northeast Asian economy cooperation: study on energy resource cooperation in Northeast Asian region

    Energy Technology Data Exchange (ETDEWEB)

    Chung, Woo Jin [Korea Energy Economics Institute, Euiwang (Korea)

    1999-12-01

    In Northeast Asian region, there are East Russia with abundant resources, Japan a large energy consumption country, Korea and China with rapidly increasing energy consumption due to their economic development, but the utilization rate of East Russian resources are very low and the resource trading and investment among Korea, China and Japan are also low. Korea and Japan use most of energy imported from Middle East. It is expected that import of petroleum and gas except coal will be increasing in China and most of imported energy will be imported mainly from the Middle East. For Korea, with not much energy resources and foreign-oriented economic system, if investment on resource development among Northeast Asian countries is active and energy transportation among these countries is liberalized, the enhancement of energy cooperation in Northeast Asia has a high possibility to provide North and South Korean energy cooperation as well as to secure energy security and to develop energy industry. Therefore, Korean government needs to promote Northeast Asian energy cooperation by taking its lead. (author). 28 refs., 8 figs., 44 tabs.

    Families of ethnic minority persons with dementia often seek help at later stages of the disease. Little is known about the effectiveness of various methods in supporting ethnic minority dementia patients' caregivers. The objective of the study was to identify smartphone and computer usage among family caregivers of dementia patients (i.e., Korean and Vietnamese Americans) to develop dementia-care education programs for them. Participants were asked various questions related to their computer or smartphone usage in conjunction with needs-assessment interviews. Flyers were distributed at two ethnic minority community centers in Southern California. Snowball recruitment was also utilized to reach out to the families of dementia patients dwelling in the community. Thirty-five family caregivers, including 20 Vietnamese and 15 Korean individuals, participated in this survey. Thirty participants (30 of 35, 85.7%) were computer users. Among those, 76.7% (23 of 30) reported daily usage and 53% (16 of 30) claimed to use social media. A majority of the participants (31 of 35, 88.6%) reported that they owned smartphones. More than half of smartphone users (18 of 29, 62%) claimed to use social media applications. Many participants claimed that they could not attend in-class education due to caregiving and/or transportation issues. Most family caregivers of dementia patients use smartphones more often than computers, and more than half of those caregivers communicate with others through social media apps. A smartphone-app-based caregiver intervention may serve as a more effective approach compared to the conventional in-class method. Multiple modalities for the development of caregiver interventions should be considered.

    Green building (GB) is part of the concept of promoting sustainability. Although GB and the concept of sustainability are well studied for environmental concerns, their business rationale and related social concerns have not been fully explored or widely accepted by the parties involved in the building sector. In this study, the situation of GB market in relation to the general building market is reviewed and the business rationales of stakeholders to invest in the GB market have been investigated from the perspective of building designers. In addition, the factors that enhance the popularity of GB have been explored and the obstacles that hinder its market have been examined. The data are collected by a questionnaire survey covering building designers in Hong Kong and Singapore, the cities that are categorized as economically developed cities in Asia. After data analysis of the survey, this paper presents the findings of the business reasons for stakeholders to be involved in GB, the most favorable conditions required to promote GB business and the important obstacles that hinder its popularity. Based on the findings, recommendations and policy implications are tendered. (author)

    Full Text Available Indigenous communities across the world have been suffering disadvantages in several domains, e.g. erosion of land rights, language and other cultural aspects, while at the same time being discriminated against when prepared to integrate into the dominant cultures. It has been argued in the literature that information communication technologies (ICTs have the potential of contributing to addressing some of these disadvantages – both in terms of rebuilding what has been eroded and facilitating integration into non-Indigenous societies. In trying to understand how ICTs can be useful for these processes, it is important to do so from a conceptual framework that encompasses the multi-dimensionality of the issues faced by Indigenous communities. The conceptual frameworks frequently used in the ICT literature tend to focus on adoption, use and diffusion of technologies rather than how the use of ICTs affects the livelihoods of the users, which is the focus of this paper. The conceptual framework is informed by the capability approach (CA, in particular by the five freedoms identified in the seminal work of Amartya Sen (2001, “Development as Freedom” (DaF. Data were collected from a purposive sample in an Indigenous community in Bangladesh, using a qualitative method to map how ICTs had affected the lives of these community members The findings suggest that the participants perceived that ICTs had made positive contributions, particularly the benefits they gained from learning how to use computers in the domains that are relevant from the perspective of the five freedoms espoused in DaF. The findings reported in this paper are useful for policy formulation in Bangladesh. As the study is contextualised in a transitional economy setting and can therefore not be generalised, but we believe that the conceptual framework has much to offer future research designed to understand how ICTs can improve the livelihoods of Indigenous individuals and

    Group dynamics of online medical faculty development programs have not been analyzed and reported in literature. Knowledge of the types of content of posted messages will help to understand group dynamics and promote participation in an asynchronous learning environment. This paper assesses group dynamics and social interactivity in an online learning environment for medical teachers in the South Asian context. Participants of a medical education fellowship program conducted by the Foundation for Advancement of International Medical Education and Research (FAIMER) Regional Institute at Christian Medical College, Ludhiana (CMCL) in India interact on a listserv called the Mentoring-Learning Web (ML-Web). Monthly topics for online discussion are chosen by fellows through a standard tool called "multi-voting". Fellows volunteer to moderate sessions and direct the pace of the discussion. We analyzed the content and process of the discussion of one particular month. The emails were categorized as those that reflected cognitive presence (dealing with construction and exploration of knowledge), teacher presence (dealing with instructional material and learning resources), and social presence, or were administrative in nature. Social emails were further classified as: affective, cohesive and interactive. Social emails constituted one-third of the total emails. Another one-quarter of the emails dealt with sharing of resources and teacher presence, while cognitive emails comprised 36.2% of the total. More than half of the social emails were affective, while a little less than one-third were cohesive. Social posts are an inevitable part of online learning. These posts promote bonding between learners and contribute to better interaction and collaboration in online learning. Moderators should be aware of their presence and use them as tools to promote interactivity.

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

  14. An Asian dilemma. Modernising the electricity sector in China and India in the context of rapid economic growth and the concern for climate change

    2001-12-01

    The research question dealt with in this report is: What are the feasible policy and technology options to modernise the electricity sector in China and India taking into account the supply and demand for electricity and given the conflict between the need for economic growth and the need to anticipate future developments in relation to the reduction of greenhouse gas emissions? The project essentially integrates three methodological approaches, a scenario approach, a bottom-up technology approach and an institutional cum stakeholder approach. Following an initial appraisal of the 'business-as-usual' scenario for the electricity sector for both countries, a range of policy and technology options was identified, as well as their potential and technical, economic and political feasibility. These options were combined and compared to the business-as-usual scenario to develop emission reduction scenarios for China and India and were tested with stakeholders to identify their feasibility and to assess the potential of using instruments at national and international level to facilitate their implementation. Although some measures have a high technical potential for reducing greenhouse gas emissions in both countries, these are not seen as particularly feasible by the stakeholders. For example end use efficiency has a very high technical emission to reduce emissions but is not given much priority in China and India (especially in the small-scale sector). Efficiency improvement in power plants and in transmission and distribution can also yield results in terms of emission reductions but are not seen as important in China. The report discusses the barriers and opportunities in relation to the various options. refs.

    Suitable algorithms based on a combination of two or more simple rapid HIV assays have been shown to have a diagnostic accuracy comparable to double enzyme-linked immunosorbent assay (ELISA) or double ELISA with Western Blot strategies. The aims of this study were to evaluate the performance of five simple rapid HIV assays using whole blood samples from HIV-infected patients, pregnant women, voluntary counseling and testing attendees and blood donors, and to formulate an alternative confirmatory strategy based on rapid HIV testing algorithms suitable for use in Tanzania. Five rapid HIV assays: Determine HIV-1/2 (Inverness Medical), SD Bioline HIV 1/2 3.0 (Standard Diagnostics Inc.), First Response HIV Card 1-2.0 (PMC Medical India Pvt Ltd), HIV1/2 Stat-Pak Dipstick (Chembio Diagnostic System, Inc) and Uni-Gold HIV-1/2 (Trinity Biotech) were evaluated between June and September 2006 using 1433 whole blood samples from hospital patients, pregnant women, voluntary counseling and testing attendees and blood donors. All samples that were reactive on all or any of the five rapid assays and 10% of non-reactive samples were tested on a confirmatory Inno-Lia HIV I/II immunoblot assay (Immunogenetics). Three hundred and ninety samples were confirmed HIV-1 antibody positive, while 1043 were HIV negative. The sensitivity at initial testing of Determine, SD Bioline and Uni-Gold was 100% (95% CI; 99.1-100) while First Response and Stat-Pak had sensitivity of 99.5% (95% CI; 98.2-99.9) and 97.7% (95% CI; 95.7-98.9), respectively, which increased to 100% (95% CI; 99.1-100) on repeat testing. The initial specificity of the Uni-Gold assay was 100% (95% CI; 99.6-100) while specificities were 99.6% (95% CI; 99-99.9), 99.4% (95% CI; 98.8-99.7), 99.6% (95% CI; 99-99.9) and 99.8% (95% CI; 99.3-99.9) for Determine, SD Bioline, First Response and Stat-Pak assays, respectively. There was no any sample which was concordantly false positive in Uni-Gold, Determine and SD Bioline assays. An

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

    Forecasters at the Space Meteorology Group (SMG) issue 30 to 90 minute forecasts for low cloud ceilings at the Space Shuttle Landing Facility (TTS) to support Space Shuttle landings. Mission verification statistics have shown ceilings to be the number one forecast challenge for SMG. More specifically, forecasters at SMG are concerned with any rapidly developing clouds/ceilings below 8000 ft in a stable, capped thermodynamic environment. Therefore, the Applied Meteorology Unit (AMU) was tasked to examine archived events of rapid stable cloud formation resulting in ceilings below 8000 ft, and document the atmospheric regimes favoring this type of cloud development. The AMU examined the cool season months of November to March during the years of 1993-2003 for days that had low-level inversions and rapid, stable low cloud formation that resulted in ceilings violating the Space Shuttle Flight Rules. The AMU wrote and modified existing code to identify inversions from the morning (-10 UTC) Cape Canaveral, FL rawinsonde (XMR) during the cool season and output pertinent sounding information. They parsed all days with cloud ceilings below 8000 ft at TTS, forming a database of possible rapidly-developing low ceiling events. Days with precipitation or noticeable fog burn-off situations were excluded from the database. In the first phase of this work, only the daytime hours were examined for possible ceiling development events since low clouds are easier to diagnose with visible satellite imagery. Phase II of this work includes expanding the database to include nighttime cases which is underway as this abstract is being written. For the nighttime cases, the AMU will analyze both the 00 UTC soundings and the 10 UTC soundings to examine those data for the presence of a low-level inversion. The 00 UTC soundings will probably not have a surface-based inversion, but the presence of inversions or "neutral" layers aloft and below 8,000 ft will most likely help define the stable

  5. Characterization of urban waste management practices in developing Asian countries: A new analytical framework based on waste characteristics and urban dimension.

    Science.gov (United States)

    Aleluia, João; Ferrão, Paulo

    2016-12-01

    This paper characterizes municipal solid waste (MSW) management practices in developing Asia, with a focus on low and middle-income countries. The analysis that is conducted supports a proposed framework that maps out the trends observed in the region in relation to two parameters, waste compositions and urban dimension, which was prepared based on a set of national and urban case studies. The management of MSW in developing Asian countries is driven, first and foremost, by a public health imperative: the collection and disposal of waste in order to avoid the spread of disease vectors from uncollected waste. This comes, however, at a high cost, with local government authorities in these countries spending up to 50% of their budgets in the provision of these services. Little or no value is derived from waste, which is typically seen as a liability and not as a resource that can be harnessed. On the other hand, in many cities in developing Asia there is an informal sector that ekes out a living from the recovery of recyclable materials found in waste. Members of this "informal waste sector" are especially active in areas that are not served by formal waste collection systems, such as slums or squatter areas. A distinctive element shared among many cities in developing Asian countries concerns the composition of the municipal solid waste. MSW in those countries tends to be richer in biodegradable organic matter, which usually accounts for more than 50% of the total waste composition, suggesting that biological methods are more appropriate for treating this organic fraction. Conversely, thermal combustion technologies, which are extensively applied in high-income countries, are technically and economically challenging to deploy in light of the lower calorific value of waste streams which are rich in organics and moisture. Specific approaches and methods are therefore required for designing adequate waste management systems in developing Asian countries. In addition

    1990-01-01

    This paper reports on natural gas which now appears ready to take a leading role on the world energy stage. Demand for natural gas, and specifically LNG, will be strong throughout the world, particularly in Asia. Indonesia and Malaysia will become much more dependent on natural gas in the Asian market. In Thailand, where remarkable economic growth has been fueled by imported oil and domestically produced natural gas, LNG may soon have to be imported from neighboring countries. The author sees Thailand's imports of natural gas increasing from 1.5 to 4.5 million tons annually. Similarly, Korea's imports of LNG will rise from 2 to 8 million tons between 1987 and 2000. In Japan, energy demand is expected to increase at an even faster rate in the 1990s. Given the opposition to nuclear power generation and growing concern about the greenhouse effect, it is likely that LNG will satisfy a major portion of Japan's increasing demand for energy. Japanese gas companies are studying the possibility of establishing a national pipeline network to move gas beyond metropolitan areas

    1991-01-01

    This paper presents a review of the Bank's involvement in financing gas projects in its developing member countries (DMC's). The paper highlights the scope of the Bank's past activities in the sector, the DMC's which had received assistance from the Bank, the types of projects financed by the Bank, the benefits expected to be derived from the projects, and the past problems encountered by the Bank. The operational framework under which past Bank lending to the gas sector was conducted is also described. The prospects of natural gas playing a prominent role as an environmentally preferred energy source to oil and coal are outlined. Indications of the direction of the Bank's future efforts to help its gas-resource-rich as well as its gas-resource-poor DMC's to quicken the use of natural gas are given. While emphasizing the Bank's contributions in helping its DMC's to increase gas supply to alleviate energy shortages, the paper stresses the important role the Bank has played and will play in institution-building and sector-development work. The paper explores the possibility for the Bank to expand its operations in the gas sector which will lead to the efficient and accelerated development of a clean energy source that will help its DMC's avoid a third oil crisis and reduce the damaging build-up of a greenhouse gas which now threatens to harm the global environment

    2012-01-01

    There appears to be virtual universal endorsement of the need for and value of acute "psychological first aid" (PFA) in the wake of trauma and disasters. In this paper, we describe the development of the curriculum for The Johns Hopkins RAPID-PFA model of psychological first aid. We employed an adaptation of the basic framework for the development of a clinical science as recommended by Millon which entailed: historical review, theoretical development, and content validation. The process of content validation of the RAPID-PFA curriculum entailed the assessment of attitudes (confidence in the application of PFA interventions, preparedness in the application of PFA); knowledge related to the application of immediate mental health interventions; and behavior (the ability to recognize clinical markers in the field as assessed via a videotape recognition exercise). Results of the content validation phase suggest the six-hour RAPID-PFA curriculum, initially based upon structural modeling analysis, can improve confidence in the application of PFA interventions, preparedness in the application of PFA, knowledge related to the application of immediate mental health interventions, and the ability to recognize clinical markers in the field as assessed via a videotape recognition exercise.

    Development of portable, reliable, sensitive, simple, and inexpensive detection system for alcohol has been an instinctive demand not only in traditional brewing, pharmaceutical, food and clinical industries but also in rapidly growing alcohol based fuel industries. Highly sensitive, selective, and reliable alcohol detections are currently amenable typically through the sophisticated instrument based analyses confined mostly to the state-of-art analytical laboratory facilities. With the growing demand of rapid and reliable alcohol detection systems, an all-round attempt has been made over the past decade encompassing various disciplines from basic and engineering sciences. Of late, the research for developing small-scale portable alcohol detection system has been accelerated with the advent of emerging miniaturization techniques, advanced materials and sensing platforms such as lab-on-chip, lab-on-CD, lab-on-paper etc. With these new inter-disciplinary approaches along with the support from the parallel knowledge growth on rapid detection systems being pursued for various targets, the progress on translating the proof-of-concepts to commercially viable and environment friendly portable alcohol detection systems is gaining pace. Here, we summarize the progress made over the years on the alcohol detection systems, with a focus on recent advancement towards developing portable, simple and efficient alcohol sensors.

  12. Did opening of the South China Sea impact development of the Asian Monsoon? Results from Oligocene microfossils, IODP Site U1435, northern South China Sea

    Kulhanek, Denise K.; Su, Xin; Li, Qianyu; Gregory, Mitch; Warny, Sophie; Clift, Peter D.

    Development of the Asian Monsoon is linked to uplift of the Himalayas and Tibetan Plateau in the Cenozoic, with good evidence for a strong monsoon system by the late Oligocene to early Miocene (e.g., Guo et al., 2002; Clift et al., 2008). However, Licht et al. (2014) suggested the presence of an Asian Monsoon in the late Eocene. Recent scientific ocean drilling in the Indian Ocean and surrounding marginal seas gives us the opportunity to test this hypothesis with newly recovered Paleogene sediment cores. International Ocean Discovery Program Expedition 349 to the South China Sea recovered a 30 m section of primarily lower Oligocene nannofossil-rich claystone at Site U1435, located near the northern continent/ocean boundary. A thick sandstone unit devoid of typical marine microfossils underlies the marine claystone. The sandstone is interpreted as a deltaic or restricted marine deposit and is dated to the Eocene based on the presence of organic-walled palynomorphs, suggesting that a hiatus of several million years likely separates the sandstone below from the Oligocene marine claystone. This hiatus is interpreted as the breakup unconformity, with paleodepths in the South China Sea increasing during the Oligocene. Thus, this claystone should record if opening of the South China Sea during the early Oligocene influenced development of the Asian Monsoon. Combined calcareous nannofossil and planktonic foraminifer biostratigraphy indicates that the 30 m section is primarily early Oligocene in age (~33.5-30 Ma) and was deposited on the middle slope, with paleodepths >500 m. Stable oxygen isotopes from planktonic foraminifers become heavier up-hole, suggestive of cooling/deepening in the region, whereas carbon isotopes record variable conditions with no distinct maxima or minima. Calcareous nannoplankton primarily live in the upper 50 m of the ocean and are sensitive to sea-surface temperature and nutrient conditions, thus making them useful recorders of paleoceanographic

    Rapid development and production of vaccines against emerging diseases requires well established, validated, robust technologies to allow industrial scale production and accelerated licensure of products. Areas covered: A versatile Vero cell platform has been developed and utilized to deliver a wide range of candidate and licensed vaccines against emerging viral diseases. This platform builds on the 35 years' experience and safety record with inactivated whole virus vaccines such as polio vaccine. The current platform has been optimized to include a novel double inactivation procedure in order to ensure a highly robust inactivation procedure for novel emerging viruses. The utility of this platform in rapidly developing inactivated whole virus vaccines against pandemic (-like) influenza viruses and other emerging viruses such as West Nile, Chikungunya, Ross River and SARS is reviewed. The potential of the platform for development of vaccines against other emerging viruses such as Zika virus is described. Expert commentary: Use of this platform can substantially accelerate process development and facilitate licensure because of the substantial existing data set available for the cell matrix. However, programs to provide vaccines against emerging diseases must allow alternative clinical development paths to licensure, without the requirement to carry out large scale field efficacy studies.

    2012-03-01

    Asians comprise more than 60% of the world's population and are the fastest growing minority group in the United States. Today's psychiatrist must learn to recognize and appreciate the unique factors that influence mental health outcomes in this group. Asian Americans are affected by psychiatric disorders at similar rates as non-Asians, but are significantly underrepresented in psychiatric clinics. When Asians and Asian Americans do present for psychiatric treatment, they often do so with higher severity of illness, and variable levels of compliance. Studies over the past three decades have suggested that pharmacokinetic and pharmacodynamic profiles of various psychotropic medications may be different in Asians, leading to differences in dosage requirements and side-effect profiles. These variations appear to be largely determined by genetic predisposition, but are also influenced by other factors such as environment, social support, cultural perceptions, and physicians' prescribing habits. In this paper, we provide an overview of biological and socio-cultural issues as they relate to psychopharmacology in Asians and Asian Americans, with the hope that a better understanding of these issues will lead to improved mental health care delivery to this population both in the United States, as well as in Asian countries.

    Zhu Jiang; Chen Wenchao; Lu Yitong; Cheng Guohua

    2008-01-01

    A rapid immunochromatographic one-step strip test was developed to specifically determine bromoxynil in surface and drinking water by competitive inhibition with the nano colloidal gold-conjugated monoclonal antibody (mAb). Bromoxynil standard samples of 0.01-10 mg L -1 in water were tested by this method and the visual limit was 0.06 mg L -1 . The assay only required 5 min and one-step by dispensing a drop of sample solution onto a strip. Parallel analysis of water samples with bromoxynil showed comparable results from one-step strip test and ELISA. Therefore, the one-step strip test is very useful as a screening method for qualitative detection of bromoxynil in water. - One-step strip test is a rapid method for qualitative detection of bromoxynil residues in water

  17. Evolution of Asian Interior Arid-Zone Biota: Evidence from the Diversification of Asian Zygophyllum (Zygophyllaceae)

    Li, Hong-Lei; Yu, Sheng-Xiang; Zhang, Lin-Jing; Wang, Wei

    2015-01-01

    The Asian interior arid zone is the largest desert landform system in the Northern Hemisphere, and has high biodiversity. Little is currently known about the evolutionary history of its biota. In this study, we used Zygophyllum, an important and characteristic component of the Asian interior arid zone, to provide new insights into the evolution of this biota. By greatly enlarged taxon sampling, we present the phylogenetic analysis of Asian Zygophyllum based on two plastid and one nuclear markers. Our phylogenetic analyses indicate that Asian Zygophyllum and Sarcozygium form a clade and Sarcozygium is further embedded within the shrub subclade. An integration of phylogenetic, biogeographic, and molecular dating methods indicates that Zygophyllum successfully colonized the Asian interior from Africa in the early Oligocene, and Asian Zygophyllum became differentiated in the early Miocene and underwent a burst of diversification in the late Miocene associated with the expansion of Asian interior arid lands due to orogenetic and climatic changes. Combining diversification patterns of other important components of the Asian interior arid zone, we propose a multi-stage evolution model for this biota: the late Eocene–early Oligocene origin, the early Miocene expansion, and the middle-late Miocene rapid expansion to the whole Asian interior arid zone. This study also demonstrates that, for Zygophyllum and perhaps other arid-adapted organisms, arid biomes are evolutionary cradles of diversity. PMID:26393796

    Laboratory diagnosis of toxocariasis is still a challenge especially in developing endemic countries with polyparasitism. In this study, three Toxocara canis recombinant antigens, rTES-26, rTES-30, and rTES-120, were expressed and used to prepare lateral flow immunoglobulin G4 (IgG4) dipsticks. The concordance of the results of the rapid test (comprising three dipsticks) with a commercial IgG-enzyme-linked immunosorbent assay (ELISA) (Cypress Diagnostics, Belgium) was compared against the concordance of two other commercial IgG-ELISA kits (Bordier, Switzerland and NovaTec, Germany) with the Cypress kit. Using Toxocara- positive samples, the concordance of the dipstick dotted with rTES-26, rTES-30, and rTES-120 was 41.4% (12/29), 51.7% (15/29), and 72.4% (21/29), respectively. When positivity with any dipstick was considered as an overall positive rapid test result, the concordance with the Cypress kit was 93% (27/29). Meanwhile, when compared with the results of the Cypress kit, the concordance of IgG-ELISA from NovaTec and Bordier was 100% (29/29) and 89.7% (26/29), respectively. Specific IgG4 has been recognized as a marker of active infection for several helminthic diseases; therefore, the two non-concordant results of the rapid test when compared with the NovaTec IgG-ELISA kit may be from samples of people with non-active infection. All the three dipsticks showed 100% (50/50) concordance with the Cypress kit when tested with serum from individuals who were healthy and with other infections. In conclusion, the lateral flow rapid test is potentially a good, fast, and easy test for toxocariasis. Next, further validation studies and development of a test with the three antigens in one dipstick will be performed.

    1991-01-01

    A generic planar 3 degree of freedom simulation was developed that supports hardware in the loop simulations, guidance and control analysis, and can directly generate flight software. This simulation was developed in a small amount of time utilizing rapid prototyping techniques. The approach taken to develop this simulation tool, the benefits seen using this approach to development, and on-going efforts to improve and extend this capability are described. The simulation is composed of 3 major elements: (1) Docker dynamics model, (2) Dockee dynamics model, and (3) Docker Control System. The docker and dockee models are based on simple planar orbital dynamics equations using a spherical earth gravity model. The docker control system is based on a phase plane approach to error correction.

    2008-11-01

    The ProteoWizard software project provides a modular and extensible set of open-source, cross-platform tools and libraries. The tools perform proteomics data analyses; the libraries enable rapid tool creation by providing a robust, pluggable development framework that simplifies and unifies data file access, and performs standard proteomics and LCMS dataset computations. The library contains readers and writers of the mzML data format, which has been written using modern C++ techniques and design principles and supports a variety of platforms with native compilers. The software has been specifically released under the Apache v2 license to ensure it can be used in both academic and commercial projects. In addition to the library, we also introduce a rapidly growing set of companion tools whose implementation helps to illustrate the simplicity of developing applications on top of the ProteoWizard library. Cross-platform software that compiles using native compilers (i.e. GCC on Linux, MSVC on Windows and XCode on OSX) is available for download free of charge, at http://proteowizard.sourceforge.net. This website also provides code examples, and documentation. It is our hope the ProteoWizard project will become a standard platform for proteomics development; consequently, code use, contribution and further development are strongly encouraged.

  8. DEVELOPMENT OF RAPID TECHNIQUE FOR DETERMINATION OF THE TOTAL MINERALIZATION OF NATURAL WATERS

    Directory of Open Access Journals (Sweden)

    T. A. Kuchmenko

    2015-01-01

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

  9. Development of Rapid Isothermal Amplification Assays for Detection of Phytophthora spp. in Plant Tissue.

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

    2015-02-01

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

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

    2017-03-01

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

    2007-11-01

    Rapid prototyping is an important element in researching new imaging analysis techniques and developing custom medical applications. In the last ten years, the open source community and the number of open source libraries and freely available frameworks for biomedical research have grown significantly. What they offer are now considered standards in medical image analysis, computer-aided diagnosis, and medical visualization. A cursory review of the peer-reviewed literature in imaging informatics (indeed, in almost any information technology-dependent scientific discipline) indicates the current reliance on open source libraries to accelerate development and validation of processes and techniques. In this survey paper, we review and compare a few of the most successful open source libraries and frameworks for medical application development. Our dual intentions are to provide evidence that these approaches already constitute a vital and essential part of medical image analysis, diagnosis, and visualization and to motivate the reader to use open source libraries and software for rapid prototyping of medical applications and tools.

    2006-01-01

    Purpose: The external audit of oncologist clinical practice is increasingly important because of the incorporation of audits into national maintenance of certification (MOC) programs. However, there are few reports of external audits of oncology practice or decision making. Our institution (The Cancer Institute, Singapore) was asked to externally audit an oncology department in a developing Asian nation, providing a unique opportunity to explore the feasibility of such a process. Methods and Materials: We audited 100 randomly selected patients simulated for radiotherapy in 2003, using a previously reported audit instrument assessing clinical documentation/quality assurance and medical decision making. Results: Clinical documentation/quality assurance, decision making, and overall performance criteria were adequate 74.4%, 88.3%, and 80.2% of the time, respectively. Overall 52.0% of cases received suboptimal management. Multivariate analysis revealed palliative intent was associated with improved documentation/clinical quality assurance (p = 0.07), decision making (p 0.007), overall performance (p = 0.003), and optimal treatment rates (p 0.07); non-small-cell lung cancer or central nervous system primary sites were associated with better decision making (p = 0.001), overall performance (p = 0.03), and optimal treatment rates (p = 0.002). Conclusions: Despite the poor results, the external audit had several benefits. It identified learning needs for future targeting, and the auditor provided facilitating feedback to address systematic errors identified. Our experience was also helpful in refining our national revalidation audit instrument. The feasibility of the external audit supports the consideration of including audit in national MOC programs

    We developed a rapid word reading test for examining the phonological processing ability of Japanese children. We prepared two versions of the test, version A and B. Each test has word and non-word tasks. Twenty-two healthy boys of third grade in primary schools participated in this validation study. For criterion related validity, we performed the serial Hiragana reading test, the sentence reading test, Raven's coloured progressive matrices (RCPM), the Token test for children, the Kana word dictation test, the standardized comprehension test of abstract words (SCTAW), and Trail Circle test. The reading times of the newly developed test correlated moderately or highly with those of the serial Hiragana reading test and the sentence reading test. However, the scores of the other tests (RCPM, Token test for children, Kana word dictation test, SCTAW, Trail Circle test) did not correlated with the reading time of the rapid word reading test. Test-retest reliabilities in the word tasks were more than moderate: 0.52 and 0.76 in versions A and B, while those in the non-word tasks were high: 0.91 and 0.88 in versions A and B. The correlation coefficient between versions A and B was 0.7 for the word tasks and 0.92 for the non-word tasks. This study showed that the rapid word reading test has substantial validity and reliability for testing the phonological processing ability of Japanese children. In addition, the non-word tasks were more suitable for selectively examining the speed of the grapheme to phoneme conversion process.

    The measurements of dissolved CO2 in seawater is of great significance for the study of global carbon cycle. At present, the commercial sensors used for dissolved CO2 measurements are mostly equipped with permeable membranes for the purpose of gas-liquid separation, with the advantages of easy operation, low cost, etc.. However, most of these devices measure CO2 after reaching gas equilibrium, so it takes a few minutes to respond, which limited its applications in rapid measurements. In this paper, a set of prototype was developed for the rapid measurements of dissolved CO2. The system was built basing the direct absorption TDLAS. To detect the CO2 absorption line located at 4991.26 cm-1 , a fiber-coupled DFB laser operating at 2004 nm was selected as the light source. A Herriott type multi-pass cavity with an effective optical path length of 10 m and an inner volume of 90 mL was used for absorption measurements. A detection limit of 26 μatm can be obtained with this compact cavity. To realize the rapid measurements of dissolved CO2, a degasser with high degassing rate was necessary. A hollow fiber membrane with a large permeable area used in this paper can achieve degassing rate up to 2.88 kPa/min. Benefitted from the high degassing rate of the degasser and high sensitivity of the compact TDLAS system, a rapid measurement of dissolved CO2 in water can be achieved within 1s time, and the response time of the prototype when the dissolved CO2 concentration changed abruptly in actual measurement was 15 s. To evaluate the performance of the prototype, comparison measurements were carried out with a commercial mass spectrometer. The dissolved CO2 in both seawater and tap-water was measured, and the experimental results showed good consistent trends with R2 of 0.973 and 0.931. The experimental results proved the feasibility of dissolved CO2 rapid measurement. In the near future, more system evaluation experiments will be carried out and the system will be further

    The trauma pandemic is one of the leading causes of death worldwide but especially in rapidly developing economies. Perhaps, a common cause of trauma-related mortality in these settings comes from the rapid expansion of motor vehicle ownership without the corresponding expansion of national prehospital training in developed countries. The resulting road traffic injuries often never make it to the hospital in time for effective treatment, resulting in preventable disability and death. The current article examines the development of a medical first responder training program that has the potential to reduce this unnecessary morbidity and mortality. An intensive training workshop has been differentiated into two progressive tiers: acute trauma training (ATT) and broad trauma training (BTT) protocols. These four-hour and two-day protocols, respectively, allow for the mass education of laypersons-such as police officials, fire brigade, and taxi and/or ambulance drivers-who are most likely to interact first with prehospital victims. Over 750 ATT participants and 168 BTT participants were trained across three Indian educational institutions at Jodhpur and Jaipur. Trainees were given didactic and hands-on education in a series of critical trauma topics, in addition to pretraining and post-training self-assessments to rate clinical confidence across curricular topics. Two-sample t-test statistical analyses were performed to compare pretraining and post-training confidence levels. Program development resulted in recruitment of a variety of career backgrounds for enrollment in both our ATT and BTT workshops. The workshops were run by local physicians from a wide spectrum of medical specialties and previously ATT-trained police officials. Statistically significant improvements in clinical confidence across all curricular topics for ATT and BTT protocols were identified (P developing settings. Program expansion can offer an exponential growth in the training rate of medical

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

    TEM is used to investigate microstructural development in a rapidly solidified Al-Fe-V-Si alloy. The as-cast microstructure of a rapidly solidified Al-Fe-V-Si alloy was found to vary depending on casting conditions and also through the thickness of ribbon. For completely Zone A ribbon, intercellular phase consists of a microquasi-crystalline phase, while for the Zone A and Zone B mixed ribbon, it consists of a silicide phase. In either case, formation of globular particles of a cluster microquasi-crystalline phase is observed near the air side of the ribbon. Annealing study shows significant differences in the final microstructure depending on the initial status of the ribbon. Completely Zone A ribbon, whose microstructure is composed of a microquasi-crystalline phase, results in a very coarse microstructure after annealing as compared to the Zone A and Zone B mixed ribbon. This result has important implications for the development of high-performance elevated-temperature Al alloys. 12 refs

    An important stage of rapid prototyping technology is generating computer 3D model of an object to be reproduced. Wide variety of techniques for 3D model generation exists beginning with manual 3D models generation and finishing with full-automated reverse engineering system. The progress in CCD sensors and computers provides the background for integration of photogrammetry as an accurate 3D data source with CAD/CAM. The paper presents the results of developing photogrammetric methods for non-contact spatial coordinates measurements and generation of computer 3D model of real objects. The technology is based on object convergent images processing for calculating its 3D coordinates and surface reconstruction. The hardware used for spatial coordinates measurements is based on PC as central processing unit and video camera as image acquisition device. The original software for Windows 9X realizes the complete technology of 3D reconstruction for rapid input of geometry data in CAD/CAM systems. Technical characteristics of developed systems are given along with the results of applying for various tasks of 3D reconstruction. The paper describes the techniques used for non-contact measurements and the methods providing metric characteristics of reconstructed 3D model. Also the results of system application for 3D reconstruction of complex industrial objects are presented.

    In many parts of the world, the possession and cultivation of Cannabis sativa L. are restricted by law. As chemical or morphological analyses cannot identify the plant in some cases, a simple yet accurate DNA-based method for identifying C. sativa is desired. We have developed a loop-mediated isothermal amplification (LAMP) assay for the rapid identification of C. sativa. By optimizing the conditions for the LAMP reaction that targets a highly conserved region of tetrahydrocannabinolic acid (THCA) synthase gene, C. sativa was identified within 50 min at 60-66°C. The detection limit was the same as or higher than that of conventional PCR. The LAMP assay detected all 21 specimens of C. sativa, showing high specificity. Using a simple protocol, the identification of C. sativa could be accomplished within 90 min from sample treatment to detection without use of special equipment. A rapid, sensitive, highly specific, and convenient method for detecting and identifying C. sativa has been developed and is applicable to forensic investigations and industrial quality control.

    Full Text Available Goose parvovirus (GPV remains as a worldwide problem in goose industry. For this reason, it is necessary to develop a new diagnostic approach that is easier and faster than conventional tests. A rapid immunochromatographic assay based on antibody colloidal gold nanoparticles specific to GPV was developed for the detection of GPV in goose allantoic fluid and supernatant of tissue homogenate. The monoclonal antibodies (Mab was produced by immunizing the BALB/c mice with purified GPV suspension, and the polyclonal antibody (pAb was produced by immunizing the rabbits with recombinant VP3 protein. The colloidal gold was prepared by the reduction of gold salt with sodium citrate coupled with Mab against GPV. The optimal concentrations of the coating antibody and capture antibody were determined to be 1.6 mg/ml and 9 μg/ml. With visual observation, the lower limit was found to be around 1.2 μg/ml. Common diseases of goose were tested to evaluate the specificity of the immune colloidal gold (ICG strip, and no cross-reaction was observed. The clinical detection was examined by carrying out the ICG strip test with 92 samples and comparing the results of these tests with those obtained via agar diffusion test and polymerase chain reaction (PCR test. Therefore, the ICG strip test was a sufficiently sensitive and accurate detection method for a rapid screening of GPV.

    Loop-mediated isothermal amplification (LAMP) is a novel method for rapid amplification of DNA. Its advantages include rapidity and minimal equipment requirement. The LAMP assay was developed for BK virus (BKV), which is a leading cause of morbidity in renal transplant recipients. The characteristics of the assay, including its specificity and sensitivity, were evaluated. BKV LAMP was performed using various incubation times with a variety of specimens, including unprocessed urine and plasma samples. A ladder pattern on gel electrophoresis, typical of successful LAMP reactions, was observed specifically only for BKV and not for other viruses. The sensitivity of the assay with 1 h of incubation was 100 copies/tube of a cloned BKV fragment. Additionally, a positive reaction was visually ascertained by a simple color reaction using SYBR green dye. BKV LAMP was also successful for urine and plasma specimens without the need for DNA extraction. Due to its simplicity and specificity, the LAMP assay can potentially be developed for “point of care” screening of BKV. PMID:17314224

    2007-01-01

    We discuss our experiences and successes with the new 'Book Sprint' methodology for use in rapid authoring and content development for technical books and documentation, using a distributed team and appropriate on-line collaborative technologies. A sprint begins by assembling a group of domain experts for a short period of time-intensive content creation. The outline, scope, and approximate length of the book are established, and key contributors are identified. This is followed by remote and distributed work over a period of a few months, focussing on the bulk of the book. The Sprint Book methodology has already been used in the 'Wireless Networking in the Developing World' and 'Bandwidth Optimization and Management' books.

    2018-01-01

    Full Text Available This study analyzes the key drivers of the relationship between economic growth and carbon emissions in six Northeast Asian countries (China, Japan, Republic of Korea, Democratic People’s Republic of Korea, Mongolia, and Russia from 1991 to 2015. We apply a decomposition analysis approach using Logarithmic Mean Divisia Index to identify the main contributing factors toward CO2 emission changes. To discuss the decomposition results in more in detail, we explain the energy portfolio change in each country to understand the energy and resource utilization strategy. From the results, we find that the key driving factors of CO2 emissions change and energy portfolio trends are different among Northeast Asian countries, driven by economic growth in China and Korea, reduced by energy efficiency improvements in Russia and the DPRK, while being relatively benign in Japan and Mongolia due to a combination of these factors. This result implies that we can better understand the regional cooperation policy for improving each driving factor to achieve sustainable development and management of CO2 emissions considering the characteristics of each country.

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

    2016-03-01

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

    Paul D. Pickell

    2014-07-01

    Full Text Available The accelerated development of energy resources around the world has substantially increased forest change related to oil and gas activities. In some cases, oil and gas activities are the primary catalyst of land-use change in forested landscapes. We discuss the challenges associated with characterizing ecological change related to energy resource development using North America as an exemplar. We synthesize the major impacts of energy development to forested ecosystems and offer new perspectives on how to detect and monitor anthropogenic disturbance during the Anthropocene. The disturbance of North American forests for energy development has resulted in persistent linear corridors, suppression of historical disturbance regimes, novel ecosystems, and the eradication of ecological memory. Characterizing anthropogenic disturbances using conventional patch-based disturbance measures will tend to underestimate the ecological impacts of energy development. Suitable indicators of anthropogenic impacts in forests should be derived from the integration of multi-scalar Earth observations. Relating these indicators to ecosystem condition will be a capstone in the progress toward monitoring forest change in landscapes undergoing rapid energy development.

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

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

    NKT cells comprise a rare, but important subset of T cells which account for ~0.2% of the total circulating T cell population. NKT cells are known to have anti-tumor functions and rapidly produce high levels of cytokines following activation. Several clinical trials have sought to exploit the effector functions of NKT cells. While some studies have shown promise, NKT cells are approximately 50% lower in cancer patients compared to healthy donors of the same age and gender, thus limiting their therapeutic efficacy. These studies indicate that baseline levels of activation should be assessed before initiating an NKT cell based immunotherapeutic strategy. The goal of this study was to develop a sensitive method to rapidly assess NKT cell function. We utilized artificial antigen presenting cells in combination with qPCR in order to determine NKT cell function in peripheral blood mononuclear cells from healthy donors and breast cancer patients. We found that NKT cell activation can be detected by qPCR, but not by ELISA, in healthy donors as well as in breast cancer patients following four hour stimulation. This method utilizing CD1d-expressing aAPCs will enhance our knowledge of NKT cell biology and could potentially be used as a novel tool in adoptive immunotherapeutic strategies.

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

    Ophiocordyceps sinensis is a valuable traditional Chinese medicine. Due to resource shortage, expensive price and huge market demand, there are many adulterants of O. sinensis in markets. Therefore, it is necessary to establish a rapid and effective method for distinguishing O. sinensis. Based on the species-specific PCR of O. sinensis, this study developed a detection kit by optimizing the components and evaluated the specificity, detection limit, repeatability and shelf life of the kit. The results showed that when the quality of O. sinensis accounted for more than 1/200 of that mixture, it could be detected successfully. Moreover, only O. sinensis could be amplified and glowed bright green fluorescence under ultraviolet light. The kit was still in effect when it was placed at 37 ℃ for three days, which indicated that it was stable and effective for one year stored in 4 ℃. The kit in the same batch under different operation conditions, and in different batch under the same operation conditions gave the same result and accuracy, which showed good repeatability of the kit. It is simple, rapid and accurate to distinguish O. sinensis from its adulterants using the kit, and lays the foundation for commercialization of traditional Chinese medicine fast detection kit.

    This paper reports on the development of a rapid and simple method for red wine authenticity confirmation during transport and processing; namely, a wine "fingerprinting" system. When wine is transported between two sites, a sample is taken and a mid-infrared (MIR) spectrum is obtained. One hundred sixty-one (n = 161) samples of three main red wine varieties grown in Australia, Shiraz, Cabernet Sauvignon, and Merlot, were collected from six commercial wineries across Australia and scanned in transmission on two MIR spectrophotometers located at The Hardy Wine Company's main site at Reynella, South Australia (Foss WineScan FT 120) (926-5012 cm-1). A similarity index (SI) method was used as a tool to classify wine samples on the basis of their spectral data. The results showed that high rates of classification were obtained when wine samples scanned in different instruments were analyzed. The SI has been proven to provide an acceptable measurement for authentication of red wine integrity during transportation. In five of the six winery data sets, the SI correctly classified 98% of the wines. It was also observed that less than 1% of wines were misclassified between the different wineries investigated. Further studies are needed in order to test the applicability of the SI in a commercial situation and to evaluate its potential as a rapid quality control tool for routine use to authenticate wine samples during transport.

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

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

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

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

    Yick, Alice G; Oomen-Early, Jody

    2008-08-01

    Until recently, research studies have implied that domestic violence does not affect Asian American and immigrant communities, or even Asians abroad, because ethnicity or culture has not been addressed. In this content analysis, the authors examined trends in publications in leading scholarly journals on violence relating to Asian women and domestic violence. A coding schema was developed, with two raters coding the data with high interrater reliability. Sixty articles were published over the 16 years studied, most atheoretical and focusing on individual levels of analysis. The terms used in discussing domestic violence reflected a feminist perspective. Three quarters of the studies were empirical, with most guided by logical positivism using quantitative designs. Most targeted specific Asian subgroups (almost a third focused on Asian Indians) rather than categorizing Asians as a general ethnic category. The concept of "Asian culture" was most often assessed by discussing Asian family structure. Future research is discussed in light of the findings.

  10. Development of a Novel, Bicombinatorial Approach to Alloy Development, and Application to Rapid Screening of Creep Resistant Titanium Alloys

    Science.gov (United States)

    Martin, Brian

    Combinatorial approaches have proven useful for rapid alloy fabrication and optimization. A new method of producing controlled isothermal gradients using the Gleeble Thermomechanical simulator has been developed, and demonstrated on the metastable beta-Ti alloy beta-21S, achieving a thermal gradient of 525-700 °C. This thermal gradient method has subsequently been coupled with existing combinatorial methods of producing composition gradients using the LENS(TM) additive manufacturing system, through the use of elemental blended powders. This has been demonstrated with a binary Ti-(0-15) wt% Cr build, which has subsequently been characterized with optical and electron microscopy, with special attention to the precipitate of TiCr2 Laves phases. The TiCr2 phase has been explored for its high temperature mechanical properties in a new oxidation resistant beta-Ti alloy, which serves as a demonstration of the new bicombinatorial methods developed as applied to a multicomponent alloy system.

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

    Directory of Open Access Journals (Sweden)

    Mathias De Roo

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

    2013-01-01

    The purpose of this study was to develop and test a novel and simple method for evaluating the disintegration time of rapidly disintegrating tablets (RDTs) in vitro, since the conventional disintegration test described in the pharmacopoeia produces poor results due to the difference of its environmental conditions from those of an actual oral cavity. Six RDTs prepared in our laboratory and 5 types of commercial RDTs were used as model formulations. Using our original apparatus, a good correlation was observed between in vivo and in vitro disintegration times by adjusting the height from which the solution was dropped to 8 cm and the weight of the load to 10 or 20 g. Properties of RDTs, such as the pattern of their disintegrating process, can be assessed by verifying the load. These findings confirmed that our proposed method for an in vitro disintegration test apparatus is an excellent one for estimating disintegration time and the disintegration profile of RDTs.

  15. Development of a Rapid Insulin Assay by Homogenous Time-Resolved Fluorescence.

    Zachary J Farino

    Full Text Available Direct measurement of insulin is critical for basic and clinical studies of insulin secretion. However, current methods are expensive and time-consuming. We developed an insulin assay based on homogenous time-resolved fluorescence that is significantly more rapid and cost-effective than current commonly used approaches. This assay was applied effectively to an insulin secreting cell line, INS-1E cells, as well as pancreatic islets, allowing us to validate the assay by elucidating mechanisms by which dopamine regulates insulin release. We found that dopamine functioned as a significant negative modulator of glucose-stimulated insulin secretion. Further, we showed that bromocriptine, a known dopamine D2/D3 receptor agonist and newly approved drug used for treatment of type II diabetes mellitus, also decreased glucose-stimulated insulin secretion in islets to levels comparable to those caused by dopamine treatment.

    1990-01-01

    Following the Chernobyl reactor accident it was rapidly appreciated that, in addition to upgrading national radiological monitoring systems, action was required to facilitate international communication of the results obtained. The first such system was established by the Vienna Convention, drawn up under the auspices of the IAEA, which came into force in September, 1986. Subsequently the EC Council of Ministers decided in December, 1987, to set up a Community system which in many ways parallels that established by the Convention but differs significantly in certain aspects concerning its legal basis, initiation criteria, data provisions and communications requirements. The present paper describes the present status of the Community system and foreseeable future developments. It is a matter of policy that, to avoid unnecessary complications, this system should be, to the maximum extent practicable, fully compatible with that established by the Convention. Where appropriate, therefore, reference is also made to the latter system

    1982-01-01

    A 32-item standardized multiple-choice and open-ended questionnaire was completed by nearly 500 male and female secondary school students in two rapidly developing Nigerian towns. About two thirds of the students reported some exposure to alcohol, and about one quarter reported some experience with tobacco. There was much less use of caffeine, methaqualone in combination with diphenhydramine, 2-ethylamino-3-phenylorcamphane in combination with vitamins, chlordiazepoxide, diazepam, cannabis and dexamphetamine. Many students fell into the "past use" category. Parents were extremely disapproving of the use of almost any drug. Many students supported stronger penalties for the use of cannabis. Non-users claimed that drugs were dangerous to health. In addition, religious beliefs were associated with abstinence from drugs.

    A colloidal gold immunochromatographic strip was developed for rapid detection of Streptococcus agalactiae (S. agalactiae) infection in tilapia. The monoclonal antibodies (mAb) 4C12 and 3A9 were used to target S. agalactiae as colloidal gold-mAb conjugate and captured antibody, respectively. The colloidal gold immunochromatographic strip was assembled via routine procedures. Optimal pH and minimum antibody levels in the reaction system for gold colloidal-mAb 4C12 conjugation were pH 7.4 and 18μg/mL, respectively. Optimal concentrations of the captured antibody 3A9 and goat anti-mouse antibody were 0.6mg/mL and 2mg/mL, respectively. The sensitivity of the strip for detecting S. agalactiae was 1.5×10 5 colony forming units (CFU). No cross-reaction was observed with other commonly encountered bacteria, including Pseudomonas fluorescens, Aeromonas hydrophila, Vibrio anguillarum and Streptococcus iniae. The assay time for S. agalactiae was less than 15min. Tilapia samples artificially infected with S. agalactiae were tested using the newly developed strip. The results indicated that blood, brain, kidney, spleen, metanephros and intestine specimens of infected fish can be used for S. agalactiae detection. The validity of the strip was maintained for 6 months at 4°C. These findings suggested that the immunochromatographic strip was effective for spot and rapid detection of S. agalactiae infected tilapia. Copyright © 2016 Elsevier B.V. All rights reserved.

    2015-06-01

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

    Five simple and rapid HIV antibody detection assays viz. Determine, Capillus, Oraquick, Unigold and Hemastrip were evaluated to examine their performance and to develop an alternative rapid test based testing algorithm for voluntary counseling and testing (VCT) in Ethiopia. All the kits were tested on whole blood, plasma and serum. The evaluation had three phases: Primary lab review, piloting at point of service and implementation. This report includes the results of the first two phases. A total of 2,693 specimens (both whole blood and plasma) were included in the evaluation. Results were compared to double Enzyme Linked Immuno-Sorbent Assay (ELISA) system. Discordant EIA results were resolved using Western Blot. The assays had very good sensitivities and specificities, 99-100%, at the two different phases of the evaluation. A 98-100% result agreement was obtained from those tested at VCT centers and National Referral Laboratory for AIDS (NRLA), in the quality control phase of the evaluation. A testing strategy yielding 100% [95% CI; 98.9-100.0] sensitivity was achieved by the sequential use of the three rapid test kits. Direct cost comparison showed serial testing algorithm reduces the cost of testing by over 30% compared to parallel testing in the current situation. Determine, Capillus/Oraquick (presence/absence of frefrigeration) and Unigold were recommended as screening, confirmation and tiebreaker tests, respectively.

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

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

    Carers and service users with intellectual disabilities from minority ethnic groups have typically been reported to be dissatisfied with the social care services they receive. However, service users themselves have rarely been asked directly about their experiences of social care. This paper aims to understand the meaning of social care services in the lives of South Asian women with intellectual disabilities, in the United Kingdom. 10 British South Asian women with mild-moderate intellectual disabilities were interviewed about their experiences of social care services. The transcripts were analysed using interpretative phenomenological analysis. The analysis produced three super-ordinate themes, which focus on how services facilitate the development of complex identities, how the participants explored their sense of being 'stuck' between cultures as they negotiated their journeys towards independence, and the triple disadvantage which they experienced as a consequence of the intersection between gender, ethnicity and disability. The participants were broadly satisfied with the role which services played in these domains, and appeared to find them valuable and helpful. The results suggest that the participants successfully managed complex identity issues, such as acculturation processes, with the support of services. It may be helpful to give more explicit consideration to the positive role which good services can play in supporting people with intellectual disabilities in the development of their identities and goals, alongside the more traditionally 'concrete' objectives of such social care. Engagement with families in 'positive risk-taking' is likely to be an important component of success. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Altered motility remains one of the important pathophysiologic factors in patients with irritable bowel syndrome (IBS) who commonly complain of abdominal pain and stool changes such as diarrhea and constipation. The prevalence of IBS has increased among Asian populations these days. Gastrointestinal (GI) physiology may vary between Asian and Western populations because of differences in diets, socio-cultural backgrounds, and genetic factors. The characteristics and differences of GI dysmotility in Asian IBS patients were reviewed. MEDLINE search work was performed including following terms, 'IBS,' 'motility,' 'transit time,' 'esophageal motility,' 'gastric motility,' 'small intestinal motility,' 'colonic motility,' 'anorectal function,' and 'gallbladder motility' and over 100 articles were categorized under 'esophagus,' 'stomach,' 'small intestine,' 'colon,' 'anorectum,' 'gallbladder,' 'transit,' 'motor pattern,' and 'effect of stressors.' Delayed gastric emptying, slow tansit in constipation predominant IBS patients, rapid transit in diarrhea predominant IBS patients, accelerated motility responses to various stressors such as meals, mental stress, or corticotrophin releasing hormones, and altered rectal compliance and altered rectal accomodation were reported in many Asian studies regarding IBS. Many conflicting results were found among these studies and there are still controversies to conclude these as unique features of Asian IBS patients. Multinational and multicenter studies are needed to be performed vigorously in order to elaborate characteristics as well as differences of altered motililty in Asian patients with IBS.

Japanese companies had to achieve a position of world-class competitiveness at a time when research and development costs were increasing. One strategy was to partially suspend the manufacturing of ethylene in Japan because Korea already had eight manufacturers of ethylene. Joint ventures also became popular as a means to revitalize and reinforce core business operations. Large numbers of Japanese chemical companies are also investing in overseas developments and there is increasing evidence of Japanese investments in China. While investments are still relatively small, dictated largely by the unpredictability of Chinese government actions, they nevertheless represent a gradual shift of investments from downstream to upstream, i.e. from assembly point to manufacturing, from the production of chemical derivatives to the production of intermediate raw materials, and eventually, from small-scale to large-scale investments

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

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

    Salmonella is a leading cause of foodborne illness in the United States, with poultry and poultry products being a primary source of infection to humans. Poultry may carry some Salmonella serovars without any signs or symptoms of disease and without causing any adverse effects to the health of the bird. Salmonella may be introduced to a flock by multiple environmental sources, but poultry feed is suspected to be a leading source. Detecting Salmonella in feed can be challenging because low levels of the bacteria may not be recovered using traditional culturing techniques. Numerous detection methodologies have been examined over the years for quantifying Salmonella in feeds and many have proven to be effective for Salmonella isolation and detection in a variety of feeds. However, given the potential need for increased detection sensitivity, molecular detection technologies may the best candidate for developing rapid sensitive methods for identifying small numbers of Salmonella in the background of large volumes of feed. Several studies have been done using polymerase chain reaction (PCR) assays and commercial kits to detect Salmonella spp. in a wide variety of feed sources. In addition, DNA array technology has recently been utilized to track the dissemination of a specific Salmonella serotype in feed mills. This review will discuss the processing of feeds and potential points in the process that may introduce Salmonella contamination to the feed. Detection methods currently used and the need for advances in these methods also will be discussed. Finally, implementation of rapid detection for optimizing control methods to prevent and remove any Salmonella contamination of feeds will be considered. PMID:22346699

    2015-02-01

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

  13. Rapid Fishery Assessment by Market Survey (RFAMS--an improved rapid-assessment approach to characterising fish landings in developing countries.

    Directory of Open Access Journals (Sweden)

    William T White

    Full Text Available The complex multi-gear, multi-species tropical fisheries in developing countries are poorly understood and characterising the landings from these fisheries is often impossible using conventional approaches. A rapid assessment method for characterising landings at fish markets, using an index of abundance and estimated weight within taxonomic groups, is described. This approach was developed for contexts where there are no detailed data collection protocols, and where consistent data collection across a wide range of fisheries types and geographic areas is required, regardless of the size of the site and scale of the landings. This methodology, which was demonstrated at seven fish landing sites/fish markets in southern Indonesia between July 2008 and January 2011, provides a rapid assessment of the abundance and diversity in the wild catch over a wide variety of taxonomic groups. The approach has wider application for species-rich fisheries in developing countries where there is an urgent need for better data collection protocols, monitoring future changes in market demographics, and evaluating health of fisheries.

    Prolific non-native organisms pose serious threats to ecosystems and economies worldwide. Nonnative bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix), collectively referred to as Asian carps, continue to colonize aquatic ecosystems throughout the central United States. These species are r-selected, exhibiting iteroparous spawning, rapid growth, broad environmental tolerance, high density, and long-distance movement. Hydrological, thermal, and physicochemical conditions are favorable for establishment beyond the current range, rendering containment and control imperative. Ecological approaches to confine Asian carp populations and prevent colonization characterize contemporary management in the United States. Foraging and reproduction of Asian carps govern habitat selection and movement, providing valuable insight for predictive control. Current management approaches are progressive and often anticipatory but deficient in human dimensions. We define predictive management of Asian carps as synthesis of ecology and human dimensions at regional and local scales to develop strategies for containment and control. We illustrate predictive management in the Upper Mississippi River System and suggest resource managers integrate predictive models, containment paradigms, and human dimensions to design effective, socially acceptable management strategies. Through continued research, university-agency collaboration, and public engagement, predictive management of Asian carps is an auspicious paradigm for preventing and alleviating consequences of colonization in the United States.

  15. Development of materials for the rapid manufacture of die cast tooling

    Hardro, Peter Jason

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

    Full Text Available During the last few years, there has been a growing interest in students getting engaged in digital game-making activities so as to enhance their thinking skills. The findings of studies that have examined the impact of such initiatives are quite positive, especially concerning the promotion of 21st century skills; however, many students seem to face difficulties in getting a deeper understanding of the game development life cycle. Additionally, students often have difficulties in meaningfully reusing and applying the concepts from various subjects, mainly mathematics and physics, into their game-making tasks or in understanding advanced programming commands while creating their games. The present study presents an innovative game-making teaching approach that suggests a series of steps for the systematic design and rapid development of motion-based touchless games, i.e., games that are based on natural user interaction technologies, like the Microsoft Kinect camera. Findings from evaluation studies in two (2 secondary schools indicate that this approach can increase student motivation, strengthen their computational thinking, enhance their understanding of geometric principles and improve their social skills.

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

    To study histone functions, it is necessary to fractionate the histones into their five classes (H1, H2A, H2B, H3 and H4) and then to subfractionate these classes into variants having slightly different primary structures and into different phosphorylated and acetylated forms. With the advent of high-performance liquid chromatography (HPLC), it was hoped that laborious and time-consuming conventional methods could be replaced by a simple, rapid, high-resolving HPLC method for fractionating histones. However, problems of irreversible adsorption of the histones to HPLC column packings discouraged this development. Our laboratory has now determined that the strong adsorption of histones to HPLC columns results from two different forces: (1) polar interactions between the histones and the silanol groups of silica-based HPLC column packing, and (2) hydrophobic interactions between the histones and the bound organic phase of the column packings. By minimizing these forces, we have succeeded in developing an HPLC method suitable for histone studies

    Conventional investment casting is one of the oldest and most economical manufacturing techniques to produce intricate and complex part geometries. However, investment casting is considered economical only if the volume of production is large. Design iterations and design optimisations in this technique proves to be very costly due to time and tooling cost for making dies for producing wax patterns. However, with the advent of Additive manufacturing technology, plastic patterns promise a very good potential to replace the wax patterns. This approach can be very useful for low volume production & lab requirements, since the cost and time required to incorporate the changes in the design is very low. This research paper discusses the steps involved for developing polymer nanocomposite filaments and checking its suitability for investment castings. The process parameters of the 3D printer machine are also optimized using the DOE technique to obtain mechanically stronger plastic patterns. The study is done to develop a framework for rapid investment casting for lab as well as industrial requirements.

    Detection of microbial contamination in pharmaceutical raw materials and finished products is a critical factor to guarantee their safety, stability, and potency. Rapid microbiological methods-such as polymerase chain reaction-have been widely applied to clinical and food quality control analysis. However, polymerase chain reaction applications to pharmaceutical quality control have been rather slow and sporadic. Successful implementation of these methods in pharmaceutical companies in developing countries requires important considerations to provide sensitive and robust assays that will comply with good manufacturing practices. In recent years several publications have encouraged the application of molecular techniques in the microbiological assessment of pharmaceuticals. One of these techniques is polymerase chain reaction (PCR). The successful application of PCR in the pharmaceutical industry in developing countries is governed by considerable factors and requirements. These factors include the setting up of a PCR laboratory and the choice of appropriate equipment and reagents. In addition, the presence of well-trained analysts and establishment of quality control and quality assurance programs are important requirements. The pharmaceutical firms should take into account these factors to allow better chances for regulatory acceptance and wide application of this technique. © PDA, Inc. 2014.

    Asian Americans are a rapidly growing racial/ethnic group in the United States. Our current understanding of Asian-American cardiovascular disease mortality patterns is distorted by the aggregation of distinct subgroups. The purpose of the study was to examine heart disease and stroke mortality rates in Asian-American subgroups to determine racial/ethnic differences in cardiovascular disease mortality within the United States. We examined heart disease and stroke mortality rates for the 6 largest Asian-American subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese) from 2003 to 2010. U.S. death records were used to identify race/ethnicity and cause of death by International Classification of Diseases-10th revision coding. Using both U.S. Census data and death record data, standardized mortality ratios (SMRs), relative SMRs (rSMRs), and proportional mortality ratios were calculated for each sex and ethnic group relative to non-Hispanic whites (NHWs). In this study, 10,442,034 death records were examined. Whereas NHW men and women had the highest overall mortality rates, Asian Indian men and women and Filipino men had greater proportionate mortality burden from ischemic heart disease. The proportionate mortality burden of hypertensive heart disease and cerebrovascular disease, especially hemorrhagic stroke, was higher in every Asian-American subgroup compared with NHWs. The heterogeneity in cardiovascular disease mortality patterns among diverse Asian-American subgroups calls attention to the need for more research to help direct more specific treatment and prevention efforts, in particular with hypertension and stroke, to reduce health disparities for this growing population.

    Napier grass Stunt Disease (NSD) is a severe disease of Napier grass (Pennisetum purpureum) in Eastern Africa, caused by the leafhopper-transmitted bacterium Candidatus Phytoplasma oryzae. The pathogen severely impairs the growth of Napier grass, the major fodder for dairy cattle in Eastern Africa. NSD is associated with biomass losses of up to 70% of infected plants. Diagnosis of NSD is done by nested PCR targeting the phytoplasma DNA, which is difficult to perform in developing countries with little infrastructure. We report the development of an easy to use, rapid, sensitive and specific molecular assay for field diagnosis of NSD. The procedure is based on recombinase polymerase amplification and targets the imp gene encoding a pathogen-specific immunodominant membrane protein. Therefore we followed a two-step process. First we developed an isothermal DNA amplification method for real time fluorescence application and then transferred this assay to a lateral flow format. The limit of detection for both procedures was estimated to be 10 organisms. We simplified the template preparation procedure by using freshly squeezed phloem sap from Napier grass. Additionally, we developed a laboratory serological assay with the potential to be converted to a lateral flow assay. Two murine monoclonal antibodies with high affinity and specificity to the immunodominant membrane protein IMP of Candidatus Phytoplasma oryzae were generated. Both antibodies specifically reacted with the denatured or native 17 kDa IMP protein. In dot blot experiments of extracts from infected plant, phytoplasmas were detected in as little as 12,5 μg of fresh plant material. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Where costs or risks are higher, evidence is lacking or supporting institutions are less developed, policymakers can struggle to make the case for low-carbon investment. This is especially the case in developing world cities where decision-makers struggle to keep up with the pace and scale of change. Focusing on Palembang in Indonesia, this paper considers the economic case for proactive investment in low-carbon development. We find that a rapidly growing industrial city in a developing country can reduce emissions by 24.1% in 2025, relative to business as usual levels, with investments of USD405.6 million that would reduce energy expenditure in the city by USD436.8 million. Emissions from the regional grid could be reduced by 12.2% in 2025, relative to business as usual trends, with investments of USD2.9 billion that would generate annual savings of USD175 million. These estimates understate the savings from reduced expenditure on energy subsidies and energy infrastructure. The compelling economic case for mainstreaming climate mitigation in this developing country city suggests that the constraints on climate action can be political and institutional rather than economic. There is therefore a need for more effective energy governance to drive the transition to a low-carbon economy. - Highlights: • We evaluate the economic case for low carbon investment in a developing world city. • Cost-effective measures could reduce emissions by 24.1% relative to BAU levels. • These pay for themselves in <1 year and generate savings throughout their lifetime. • Further savings come from reduced expenditure on energy infrastructure, subsidies. • Limitations on climate action seem to be political/institutional – not economic

    Previously, resistance of malaria parasite to chloroquine has been restricted only to Plasmodium falciparum. Recently, there have been many reports of chloroquine-resistant Plasmodium vivax. One of the mechanisms of chloroquine resistance is the decreased uptake of chloroquine or rapid efflux of the drug from the food vacuole of the parasite. In this study, we have measured the rapid efflux of IH-chloroquine in fifty blood samples from patients with P Vivax infection. All 50 patients were hospitalised for 28 days for the standard treatment with chloroquine. It was found that seven patients who did not respond to the standard regimen of chloroquine have parasites with rapid effluxes of IH-chloroquine. Since rapid effluxes of IH-chloroquine in the resistant parasites showed strong correlation with in vivo 28 days clinical trial, this assay could be used as rapid assessment of chloroquine resistance in patients with P vivax infection

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

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

    An impediment to progress in mood disorders research is the lack of analytically valid and qualified diagnostic and treatment biomarkers. Consistent with the National Institute of Mental Health (NIMH)'s Research Domain Criteria (RDoC) initiative, the lack of diagnostic biomarkers has precluded us from moving away from a purely subjective (symptom-based) toward a more objective diagnostic system. In addition, treatment response biomarkers in mood disorders would facilitate drug development and move beyond trial-and-error toward more personalized treatments. As such, biomarkers identified early in the pathophysiological process are proximal biomarkers (target engagement), while those occurring later in the disease process are distal (disease pathway components). One strategy to achieve this goal in biomarker development is to increase efforts at the initial phases of biomarker development (i.e. exploration and validation) at single sites with the capability of integrating multimodal approaches across a biological systems level. Subsequently, resultant putative biomarkers could then undergo characterization and surrogacy as these latter phases require multisite collaborative efforts. We have used multimodal approaches - genetics, proteomics/metabolomics, peripheral measures, multimodal neuroimaging, neuropsychopharmacological challenge paradigms and clinical predictors - to explore potential predictor and mediator/moderator biomarkers of the rapid-acting antidepressants ketamine and scopolamine. These exploratory biomarkers may then be used for a priori stratification in larger multisite controlled studies during the validation and characterization phases with the ultimate goal of surrogacy. In sum, the combination of target engagement and well-qualified disease-related measures are crucial to improve our pathophysiological understanding, personalize treatment selection, and expand our armamentarium of novel therapeutics. © 2013 Wiley Periodicals, Inc.

  11. Asian migration to Australia: food and health consequences.

    Wahlqvist, Mark L

    2002-01-01

    Australia's food and health patterns are inextricably and increasingly linked with Asia. Indigenous Australians arrived in the continent via Asia and have linguistic connections with people who settled in south India; there was interaction and food trade between both South-East Asia and China and northern indigenous Australians over thousands of years. After European settlement in 1788, there have been several and increasing (apart from the period of the infamous White Australian Policy following the Colonial period and Independence, with Federation, in 1901) waves of Asian migration, notably during the gold rush (Chinese), the building of the overland Telegraph (Afghans), the Colombo Plan and Asian student education in Australia from the 1950s onwards (South-Eeast Asians), and with refugees (Vietnamese and mainland Chinese), and business (late twentieth century) and progressive family reunion. Each wave has injected additional food cultural elements and caused a measure of health change for migrants and host citizens. Of principal advantage to Australia has been the progressive diversification of the food supply and associated health protection. This has increased food security and sustainability. The process of Australian eating patterns becoming Asianized is evident through market garden development (and the introduction of new foods), fresh food markets and groceries, restaurants and the development of household cooking skills (often taught by student boarders). Most of the diversification has been with grain (rice), legumes (soy), greens, root vegetables, and various 'exotic fruits'. Food acculturation with migration is generally bi-directional. Thus, for Asians in Australia, there has been a decrease in energy expenditure (and a lower plane of energy throughput), an increase in food energy density (through increased fat and sugary drink intakes), and a decrease in certain health protective foods (lentils, soy, greens) and beverages (tea). This sets the stage

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

    2010-01-01

    In this paper the applicability of the RIAM method (rapid impact assessment matrix) is evaluated in the context of impact significance assessment. The methodological issues considered in the study are: 1) to test the possibilities of enlarging the scoring system used in the method, and 2) to compare the significance classifications of RIAM and unaided decision-making to estimate the consistency between these methods. The data used consisted of projects for which funding had been applied for via the European Union's Regional Development Trust in the area of Central Finland. Cases were evaluated with respect to their environmental, social and economic impacts using an assessment panel. The results showed the scoring framework used in RIAM could be modified according to the problem situation at hand, which enhances its application potential. However the changes made in criteria B did not significantly affect the final ratings of the method, which indicates the high importance of criteria A1 (importance) and A2 (magnitude) to the overall results. The significance classes obtained by the two methods diverged notably. In general the ratings given by RIAM tended to be smaller compared to intuitive judgement implying that the RIAM method may be somewhat conservative in character.

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

    1987-01-01

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

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

  2. Rapid development of non-alcoholic steatohepatitis in Psammomys obesus (Israeli sand rat.

    Briana Spolding

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

    (a) real-time patient lists of registry patients and (b) EDW-gener-ated CQM data. Agile project management methods were employed, including co-development, lightweight requirements documentation with User Stories and acceptance criteria, and time-boxed iterative development of EHR features in 2-week "sprints" for rapid-cycle feedback and refinement. Using this approach, in calendar year 2015 we developed a total of 43 specialty chronic disease registries, with 111 new EHR data collection and clinical decision support tools, 163 new clinical quality measures, and 30 clinic-specific dashboards reporting on both real-time patient care gaps and summarized and vetted CQM measure performance trends. This study suggests concurrent design of EHR data collection tools and reporting can quickly yield useful EHR structured data for chronic disease registries, and bodes well for efforts to migrate away from manual abstraction. This work also supports the view that in new EHR-based registry development, as in new product development, adopting agile principles and practices can help deliver valued, high-quality features early and often.

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

    Full Text Available In developing countries, official development assistance (ODA is generally perceived to be an alternative means to develop infrastructure. Donor countries may expect benefits such as increased construction project orders in recipient countries. However, it remains arguable whether ODA contributes to reciprocal relations between recipient and donor countries. The case of South Korea can provide empirical data given that its government has expanded the amount of ODA to encourage overseas construction business while supporting Southeast Asian countries. In this research, gross national income (GNI, gross domestic product (GDP, foreign direct investment (FDI, and construction project orders awarded by South Korean construction companies in Vietnam, Bangladesh and Sri Lanka are analyzed according to the variation of ODA awarded by South Korea. The analysis results show that the influence of ODA upon economic situation of recipient countries varies according to their economic volume and development policy. From the donor country’s perspective, enhanced performance of construction business can be expected by means of cooperation with local construction business.

    2011-10-01

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

    Immunochromatography is a rapid, reliable, and cost effective method of detecting biowarfare agents. The format is similar to that of an over-the-counter pregnancy test. A sample is applied to one end of a cassette and then a control line, and possibly a sample line, are visualized at the other end of the cassette. The test is based upon a sandwich assay. For the control, a line of Protein A is immobilized on the membrane. Gold nanoparticle bound IgG flows through the membrane and binds the Protein A, creating a visible line on the membrane. For the sample, one epitope is immobilized on the membrane and another epitope is attached to gold nanoparticles. The sample binds gold bound epitope, travels through the membrane, and binds membrane bound epitope. The two epitopes are not cross-reactive, therefore a sample line is only visible if the sample is present. In order to efficiently screen for binders to a sample target, a novel, Continuous Magnetic Activated Cell Sorter (CMACS) has been developed on a disposable, microfluidic platform. The CMACS chip quickly sorts E. coli peptide libraries for target binders with high affinity. Peptide libraries, are composed of approximately ten million bacteria, each displaying a different peptide on their surface. The target of interest is conjugated to a micrometer sized magnetic particle. After the library and the target are incubated together to allow binding, the mixture is applied to the CMACS chip. In the presence of patterned nickel and an external magnet, separation occurs of the bead-bound bacteria from the bulk material. The bead fraction is added to bacterial growth media where any attached E. coli grow and divide. These cells are cloned, sequenced, and the peptides are assayed for target binding affinity. As a proof-of-principle, assays were developed for human C-reactive protein. More defense relevant targets are currently being pursued.

    Over the past five years the Center for Minimally Invasive Radiation Biodosimetry at Columbia University has developed the Rapid Automated Biodosimetry Tool (RABiT), a completely automated, ultra-high throughput biodosimetry workstation. This paper describes recent upgrades and reliability testing of the RABiT. The RABiT analyses fingerstick-derived blood samples to estimate past radiation exposure or to identify individuals exposed above or below a cut-off dose. Through automated robotics, lymphocytes are extracted from fingerstick blood samples into filter-bottomed multi-well plates. Depending on the time since exposure, the RABiT scores either micronuclei or phosphorylation of the histone H2AX, in an automated robotic system, using filter-bottomed multi-well plates. Following lymphocyte culturing, fixation and staining, the filter bottoms are removed from the multi-well plates and sealed prior to automated high-speed imaging. Image analysis is performed online using dedicated image processing hardware. Both the sealed filters and the images are archived. We have developed a new robotic system for lymphocyte processing, making use of an upgraded laser power and parallel processing of four capillaries at once. This system has allowed acceleration of lymphocyte isolation, the main bottleneck of the RABiT operation, from 12 to 2 sec/sample. Reliability tests have been performed on all robotic subsystems. Parallel handling of multiple samples through the use of dedicated, purpose-built, robotics and high speed imaging allows analysis of up to 30,000 samples per day.

    1999-10-01

    Financing of the Theun-Hinboun hydroelectric project in Laos, developed by Statkraft, the Norwegian state utility and Vattenfall, its Swedish counterpart, is critiqued. The two utilities put up $ 22 million for Nordic Hydropower's stake in the project and the Norwegian agency for development cooperation provided $ 8 million more for feasibility study, design and environmental mitigation plans. The project was supervised by Nordic Hydropower, a company which also has the contract for operation and management. Electrical and mechanical equipment was supplied by Norwegian and Swedish companies with financing from Nordic export credit agencies and the multilateral Nordic Investment Bank. Proponents of the project consider it as a great success, a 'first' in terms of foreign investment, legal framework, financing, cross-border electricity sale (to Thailand) and logistics. This report suggests that the biggest success of the project's proponents has been their ability to cajole private investors into an otherwise 'unbankable' venture in Laos, which would never have been backed by commercial lenders, who quite apart from country-specific risks, regard hydrodams as high-risk, low return investments, with a reputation for cost overruns and delays due to environmental problems and public opposition, had it not been for the zeal of the Asian Development Bank for public-private partnership. It is charged that as a result of this zeal, willingly assisted by the Nordic export credit agencies, the Government of Laos, and the Electricity Generating Authority of Thailand (EGAT), each for its private reasons, taxpayers responsible for these institutions have been forced to shoulder risks that the private sector prudently refused to take. As part-owners of the project, Lao citizens owe the Asian Development Bank $ 60 million, taxpayers in Nordic countries are responsible for $ 70 million and Thai taxpayers (owners of 20 per cent of the project) will also have to pay irrespective of

    Burke, B.F.

    1994-01-01

    Asia offers some of the best growth opportunities to the global refining industry. Many of its nations are in the process of industrializing, with a rapid rise in living standards and associated energy use. Growth trends are firmly established, with petroleum use in particular increasing rapidly as modern transport infrastructures develop. Of perhaps greater importance is Asia's potential for continued growth based on population and GDP trends. While the expected growth offers a wide range of opportunities, succeeding in the unique Asian marketplace will be a challenge mastered by only a few new entrants. This paper will examine some of the critical issues that will drive success and shape the refining business in Asia. Industry fundamentals will be reviewed, with a focus on growth and profit drivers. With the fundamental framework established, the unique challenges posed by the Asian environment, including cultural issues, investment requirements, regulatory trends and issues in market development will be discussed. The ability to succeed in Asia by identifying factors that create local advantage within a very diverse region will be discussed. The need to merge corporate capabilities and objectives with regional opportunities is the key requirement to succeed in entering or expanding in the region

    2015-01-01

    By using the ILSI network in Asia, we are holding a session focused on food safety programs in several Asian areas. In view of the external environment, it is expected to impact the global food system in the near future, including the rapid increase in food demand and in public health services due to population growth, as well as the threats to biosecurity and food safety due to the rapid globalization of the food trade. Facilitating effective information sharing holds promise for the activation of the food industry. At this session, Prof. Hwang shares the current situation of Food Safety and Sanitation Regulations in Taiwan. Dr. Liu provides a talk on the role of risk assessment in food regulatory control focused on aluminum-containing food additives in China. After the JECFA evaluation of aluminum-containing food additives in 2011, each country has carried out risk assessment based on dietary intake surveys. Ms. Chan reports on the activities of a working group on Food Standards Harmonization in ASEAN. She also explains that the ILSI Southeast Asia Region has actively supported the various ASEAN Working Groups in utilizing science to harmonize food standards. Prof. Park provides current research activities in Korea focused on the effect of climate change on food safety. Climate change is generally seen as having a negative impact on food security, particularly in developing countries. We use these four presentations as a springboard to vigorous discussion on issues related to Food Safety in Asia.

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

    National-scale water-quality data sets for the United States have been available for several decades; however, groundwater models to interpret these data are available for only a small percentage of the country. Generalized models may be adequate to explain and project groundwater-quality trends at the national scale by using regional scale models (defined as watersheds at or between the HUC-6 and HUC-8 levels). Coast-to-coast data such as the National Hydrologic Dataset Plus (NHD+) make it possible to extract the basic building blocks for a model anywhere in the country. IPython notebooks have been developed to automate the creation of generalized groundwater-flow models from the NHD+. The notebook format allows rapid testing of methods for model creation, calibration, and analysis. Capabilities within the Python ecosystem greatly speed up the development and testing of algorithms. GeoPandas is used for very efficient geospatial processing. Raster processing includes the Geospatial Data Abstraction Library and image processing tools. Model creation is made possible through Flopy, a versatile input and output writer for several MODFLOW-based flow and transport model codes. Interpolation, integration, and map plotting included in the standard Python tool stack also are used, making the notebook a comprehensive platform within on to build and evaluate general models. Models with alternative boundary conditions, number of layers, and cell spacing can be tested against one another and evaluated by using water-quality data. Novel calibration criteria were developed by comparing modeled heads to land-surface and surface-water elevations. Information, such as predicted age distributions, can be extracted from general models and tested for its ability to explain water-quality trends. Groundwater ages then can be correlated with horizontal and vertical hydrologic position, a relation that can be used for statistical assessment of likely groundwater-quality conditions

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

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

    We describe a novel method for rapid and quantitative evaluation of the degree of radiation-induced apoptosis in the developing brain of medaka (Oryzias latipes). Embryos at stage 28 were irradiated with 1, 2, 3.5, and 5 Gy x-ray. Living embryos were stained with a vital dye, acridine orange (AO), for 1-2 h, and whole-mount brains were examined under an epifluorescence microscope. From 7 to 10 h after irradiation with 5 Gy x-ray, we found two morphologically different types of AO-stained structures, namely, small single nuclei and rosette-shaped nuclear clusters. Electron microscopy revealed that these two distinct types of structures were single apoptotic cells with condensed nuclei and aggregates of apoptotic cells, respectively. From 10 to 30 h after irradiation, a similar AO-staining pattern was observed. The numbers of AO-stained rosette-shaped nuclear clusters and AO-stained single nuclei increased in a dose-dependent manner in the optic tectum. We used the number of AO-stained rosette-shaped nuclear clusters/optic tectum as an index of the degree of radiation-induced brain cell death at 20-24 h after irradiation. The results showed that the number of rosette-shaped nuclear clusters/optic tectum in irradiated embryos exposed to 2 Gy or higher doses was highly significant compared to the number in nonirradiated control embryos, whereas no difference was detected at 1 Gy. Thus, the threshold dose for brain cell death in medaka embryos was taken as being between 1-2 Gy, which may not be so extraordinarily large compared to those for rodents and humans. The results show that medaka embryos are useful for quantitative evaluation of developmental neurocytotoxic effects of radiation. (author)

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

    Thermostable direct hemolysin (TDH) and TDH-related hemolysin (TRH) are major virulence factors of enteropathogenic Vibrio parahaemolyticus. TDH and TRH are bacterial exotoxins, and their presence in culture medium serves as a specific marker for detecting this significant pathogen. Here, we developed and evaluated an immunochromatographic assay (TDH/TRH-ICA) to simultaneously or individually detect TDH and TRH. The TDH/TRH-ICA detected TDH in all broth cultures of 47 V. parahaemolyticus strains carrying tdh. The genes encoding TRH are classified as variants trh1 and trh2, and TRH was detected in all broth cultures of 25 V. parahaemolyticus strains carrying trh1 and certain proportion (5/31) of broth cultures of V. parahaemolyticus strains carrying trh2. In contrast, TDH and TRH were not detected in broth cultures of 12 non-enteropathogenic V. parahaemolyticus strains without tdh and trh. It was difficult to detect TRH2 using the TDH/TRH-ICA. However, TRH2 may not serve as a suitable marker for detecting enteropathogenic V. parahaemolyticus, and evidence indicates that TRH2 may not contribute to enteropathogenesis. Further, a screening method using a combination of TDH/TRH-ICA and SPP medium supplemented with 1.5% NaCl (modified-SPP medium) detected oyster samples artificially spiked with 1.1-22 colony-forming units of enteropathogenic V. parahaemolyticus per 25g of oysters within approximately 8.5h, including the enrichment culture. The assay may serve as a method that facilitates the rapid and easy detection of raw oysters contaminated with enteropathogenic V. parahaemolyticus. Copyright © 2017. Published by Elsevier B.V.

    The detection of microcontaminants in aquatic environments raises concerns about their potential to exert ecotoxicological effects and impact human health. In contrast to freshwater habitats, little information is available on environmental concentrations in urban estuarine and marine environments. This study investigated an extensive range of organic and inorganic microcontaminants in the Darwin Harbour catchment, a tropical estuary in northern Australia undergoing rapid urbanisation and industrial development. We sampled wastewater effluent and surface water from seven sites in Darwin Harbour for pharmaceuticals and personal care products, alkylphenols, hormones, pesticides, herbicides and metals. In vitro bioassays were used to estimate the (anti)estrogenic and (anti)androgenic activities of samples. Seventy-nine of 229 organic microcontaminants analysed were detected at concentrations ranging from 0.01 to 20 μg/L, with acesulfame, paracetamol, cholesterol, caffeine, DEET and iopromide detected at the highest concentrations in wastewater effluent (20 μg/L, 17 μg/L, 11 μg/L, 11 μg/L, 10 μg/L and 7.6 μg/L, respectively). Levels of estrogenic activity ranged from estradiol equivalency quotients (EEQs) of <0.10 to 6.29±0.16 ng/L while levels of androgenic activity ranged from dihydrotestosterone equivalency quotients (DHTEQs) of <3.50 to 138.23±3.71 ng/L. Environmental concentrations of organic microcontaminants were comparable to ranges reported from aquatic environments worldwide with sewage effluent discharges representing the dominant source of entry into Darwin Harbour. The measured concentration range of DEET was higher than ranges reported in previous studies. Copyright © 2015 Elsevier B.V. All rights reserved.

  8. Development of Novel Method for Rapid Extract of Radionuclides from Solution Using Polymer Ligand Film

    Science.gov (United States)

    Rim, Jung H.

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

    The proportion of young people in New Zealand identifying with Asian ethnicities has increased considerably. Despite some prevalent health concerns, Asian youth are less likely than non-Asian peers to seek help. As preparatory research towards a more nuanced approach to service delivery and public policy, this qualitative study aimed to identify young Asian New Zealanders' perspectives on best approaches to investigate health issues of priority concern to them. Three semi-structured focus group discussions were conducted with 15 Asian youth leaders aged 18-24 years. Using an inductive approach for thematic analysis, key themes were identified and analysed. Study participants considered ethno-cultural identity, racism and challenges in integration to play significant roles influencing the health of Asian youth (especially mental health) and their access to health services. While emphasising the importance of engaging young Asians in research and service development so that their needs and aspirations are met, participants also highlighted the need for approaches that are cognisant of the cultural, contextual and intergenerational dimensions of issues involved in promoting youth participation. Research that engages Asian youth as key agents using methods that are sensitive to their cultural and sociological contexts can inform more responsive health services and public policy. This is of particular relevance in primary health care where culturally competent services can mitigate risks of unmet health needs and social isolation.

    The majority of orthopaedic screws are designed, tested and manufactured by existing orthopaedics companies and are predominantly developed with healthy bone in mind. The timescales and costs involved in the development of a new screw design, for example, for osteoporotic bone, are high. In this study, standard wood screws were used to analyse the concept of using three-dimensional printing, or rapid prototyping, as a viable stage of development in the design of a new bone screw. Six wood screws were reverse engineered and printed in polymeric material using stereolithography. Three of the designs were also printed in Ti6Al4V using direct metal laser sintering; however, these were not of sufficient quality to test further. Both the original metal screws (metal) and polymeric rapid prototyping screws were then tested using standard pull-out tests from low-density polyurethane blocks (Sawbones). Results showed the highest pull-out strengths for screws with the longest thread length and the smallest inner diameter. Of the six screw designs tested, five showed no more than a 17% variance between the metal and rapid prototyping results. A similar pattern of results was shown between the screw designs for both the metal and rapid prototyping screws in five of the six cases. While not producing fully comparable pull-out results to orthopaedic screws, the results from this study do provide evidence of the potential usefulness and cost-effectiveness of rapid prototyping in the early stages of design and testing of orthopaedic screws.

    Symptom assessment has increasingly focused on the evaluation of total symptom distress or burden rather than assessing only individual symptoms. The challenge for clinicians and researchers alike is to assess symptoms, and to determine the symptom distress associated with the symptoms and the patient's ability for symptom management without a lengthy and burdensome assessment process. The objective of this article was to discuss the psychometric evaluation of a brief general symptom distress scale (GSDS) developed to assess specific symptoms and how they rank in relation to each other, the overall symptom distress associated with the symptom schema, and provide an assessment of how well or poorly that symptom schema is managed. Results from a pilot study about the initial development of the GSDS with 76 hospitalized patients are presented, followed by a more complete psychometric evaluation of the GSDS using three samples of cancer patients (n=190) and their social network members, called partners in these studies (n=94). Descriptive statistics were used to describe the GSDS symptoms, symptom distress, and symptom management. Point biserial correlations indexed the associations between dichotomous symptoms and continuous measures, and conditional probabilities were used to illustrate the substantial comorbidities of this sample. Internal consistency was examined using the KR-20 coefficient, and test-retest reliability was examined. Construct validity and predictive validity also were examined. The GSDS demonstrated satisfactory internal consistency and test-retest reliability, and good construct validity and predictive validity. The total score on the GSDS, symptom distress, and symptom management correlated significantly with related constructs of depression, positive and negative affect, and general health. The GSDS was able to demonstrate its ability to distinguish between those with or without chronic illness, and was able to significantly predict scores on

    Background/Aims Environmental factors such as food, lifestyle and prevalence of Helicobacter pylori infection are widely different in Asian countries compared to the West, and physiological functions and genetic factors of Asians may also be different from those of Westerners. Establishing an Asian consensus for functional dyspepsia is crucial in order to attract attention to such data from Asian countries, to articulate the experience and views of Asian experts, and to provide a relevant guide on management of functional dyspepsia for primary care physicians working in Asia. Methods Consensus team members were selected from Asian experts and consensus development was carried out using a modified Delphi method. Consensus teams collected published papers on functional dyspepsia especially from Asia and developed candidate consensus statements based on the generated clinical questions. At the first face-to-face meeting, each statement was reviewed and e-mail voting was done twice. At the second face-to-face meeting, final voting on each statement was done using keypad voting system. A grade of evidence and a strength of recommendation were applied to each statement according to the method of the GRADE Working Group. Results Twenty-nine consensus statements were finalized, including 7 for definition and diagnosis, 5 for epidemiology, 9 for pathophysiology and 8 for management. Algorithms for diagnosis and management of functional dyspepsia were added. Conclusions This consensus developed by Asian experts shows distinctive features of functional dyspepsia in Asia and will provide a guide to the diagnosis and management of functional dyspepsia for Asian primary care physicians.

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

Linagliptin, a member of dipeptidyl peptidase-4 inhibitor class, is unique in its nonlinear pharmacokinetics with the characteristics of rapid attainment of steady state, little accumulation, predominantly nonrenal route of elimination, prolonged terminal half-life, and sustained inhibition of dipeptidyl peptidase-4 enzyme. No clinically relevant difference in pharmacokinetics was observed between Asians and non-Asians. The management of type 2 diabetes is increasingly challenging with the progression of disease, especially with the requirements of minimal hypoglycemia, weight gain, fluid retention, and other adverse effects. Linagliptin was efficacious and well-tolerated in Asian type 2 diabetes patients with or without renal or hepatic dysfunctions, comparable to that in Caucasians. This review will focus on the usage of linagliptin in clinical studies in Asians. Keywords: linagliptin, Asians, type 2 diabetes

    The Asian School of Nuclear Medicine (ASNM) was formed in February 2003, with the ARCCNM as the parent body. Aims of ASNM: 1. To foster Education in Nuclear Medicine among the Asian countries, particularly the less developed ones. 2. To promote training of Nuclear Medicine Physicians in cooperation with government agencies, IAEA and universities and societies. 3. To assist in national and regional training courses, award continuing medical education (CME) points and provide regional experts for advanced educational programmes. 4. To work towards awarding of diplomas or degrees in association with recognized universities by distance learning and practical attachments, with examinations. The ASNM works toward a formal training courses leading to the award of a certificate in the long term. The most fundamental job of the ASNM remains the transfer of knowledge from the more developed countries to the less developed ones in the Asian region. The ASNM could award credit hours to the participants of training courses conducted in the various countries and conduct electronic courses and examinations. CME programmes may also be conducted as part of the regular ARCCNM meetings and the ASNM will award CME credit points for such activities

  20. The Asian Future of Evolutionary Psychology

    2006-01-01

    Full Text Available Asia's population, wealth, cognitive capital, and scientific influence are growing quickly. Reasonable demographic, economic, and psychometric projections suggest that by the mid-21st century, most of the world's psychology will be done in Asia, by Asians. Even if evolutionary psychology wins the battles for academic respectability in the United States and European Union, if it ignores the rise of Asian psychology, it will fail to have any serious, long-term, global influence in the behavioral sciences after the current generations of researchers are dead. I outline a ‘marketing strategy’ for promoting evolutionary psychology in the current Asian powers (Japan, South Korea, Taiwan, Hong Kong, Singapore, the new Asian mega-powers (China, India, and other developing Asia countries (e.g. Vietnam, Thailand, Malaysia, in a way that takes advantage of Asia's relative secularism, freedom from political correctness, sex-positive social attitudes, and intellectual traditions of Hinduism, Buddhism, and Confucianism.

    China has been experiencing increased concentrations of aerosols, commonly attributed to the large increases in emissions associated with the rapid economic development. We show by using a chemical transport model driven by the assimilated meteorological fields that the observed decadal-scale weakening of the East Asian summer monsoon also contributed to the increases in aerosols in China. We find that the simulated aerosol concentrations have strong negative correlations with the strength of the East Asian Summer monsoon. Accounting for sulfate, nitrate, ammonium, black carbon, and organic carbon aerosols, the summer surface-layer PM2.5 concentration averaged over eastern China (110°-125°E, 20°-45°N) can be 17.7% higher in the weakest monsoon years than in the strongest monsoon years. The weakening of the East Asian Summer monsoon increases aerosol concentrations mainly by the changes in atmospheric circulation (the convergence of air pollutants) in eastern China.

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

    The world economy development depends on the development of energy resource. The general energy resource which is mainly fossil fuel will bring damage to the global environment. To stop the global environment becoming worse, cleaner energy will be used in the twenty-first century. The situation which the Guangdong economic growth rate is higher than that of inland average will not change in short period. Economic development requires the suitable electric power supply. The foreground of Guangdong electric power development will be hopeful. To develop electric power is to develop coal, oil, gas, nuclear, hydroelectric and the other renewable power. As to Guangdong, because the environmental pollution is quite serious, it is impossible to develop much more coal-fired power plants. Our country is oil net importer, oil-fired power plants are also restricted. It is acceptable to import natural gas in appropriate degree to generate electricity in the near future to improve environment. To develop hydraulic power is more and more difficult in Guangdong. The hydraulic power from the southwest of China is only as the complement of the Guangdong energy resource, and it is impossible to primarily solve the energy shortage problem. Sunlight, wind, ocean power and terrestrial heat etc. are clean renewable energy, but they can't be used as the wholesale stable industry power. So to develop nuclear power is the certain selection to solve the energy shortage problem and reduce the environmental pollution in Guangdong. (author)

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

    Full Text Available The genetic sequence variation of people from the Indian subcontinent who comprise one-quarter of the world's population, is not well described. We carried out whole genome sequencing of 168 South Asians, along with whole-exome sequencing of 147 South Asians to provide deeper characterisation of coding regions. We identify 12,962,155 autosomal sequence variants, including 2,946,861 new SNPs and 312,738 novel indels. This catalogue of SNPs and indels amongst South Asians provides the first comprehensive map of genetic variation in this major human population, and reveals evidence for selective pressures on genes involved in skin biology, metabolism, infection and immunity. Our results will accelerate the search for the genetic variants underlying susceptibility to disorders such as type-2 diabetes and cardiovascular disease which are highly prevalent amongst South Asians.

    finally by providing generic functionalities compliant to the ECSS-E-70-41A standard the proposed framework can provide a great boost in productivity. Together with open source tools such like the GNU tool-chain, Eclipse SDK, the simulation framework OpenSimKit, the emulator QEMU, the proposed on-board software framework forms an integrated development framework. It is possible to design, code and build the on-board software together with the operating system and then run it on a simulated satellite for performance analysis and debugging purposes. This makes it possible to rapidly develop and deploy a full-fledged satellite on-board software with minimal cost and in a limited time frame.

    Botrytis cinerea, a typical "high-risk" pathogenic fungus that rapidly develops resistance to fungicides, affects more than 1,000 species of 586 plant genera native to most continents and causes great economic losses. Therefore, a rapid and sensitive assay of fungicide resistance development in B. cinerea populations is crucial for scientific management. In this study, we established a Loop-mediated isothermal amplification (LAMP) system for the monitoring and evaluation of the risk of development of B. cinerea resistance to QoI fungicides; the method uses two LAMP assays. The first assay detects G143A mutants of B. cinerea, which are highly resistance to QoI fungicides. BCbi143/144 introns in B. cinerea are then detected by the second assay. HNB acts as a visual LAMP reaction indicator. The optimum reaction conditions of the LAMP assays were 61 °C for 50 min, and the detection limit of the LAMP assays was 100 × 10 -4  ng/μl. We directly pre-treated the field samples by using All-DNA-Fast-Out to extract DNA within ten minutes, then performed the LAMP assay to achieve one-step rapid detection. In conclusion, we established a rapid and sensitive LAMP assay system for resistance risk assessment and for monitoring QoI-resistance of B. cinerea in the field.

  16. The Asian methanol market

    1995-01-01

    For the purpose of this presentation, Asia has been broadly defined as a total of 15 countries, namely Japan, Korea, Taiwan, China, Hong Kong, the Philippines, Thailand, Malaysia, Singapore, Indonesia, Myanmar, India, Vietnam, Australia and New Zealand. In 1994 and the first half of 1995, the methanol industry and its derivative industries experienced hard time, because of extraordinarily high methanol prices. In spite of this circumstance, methanol demand in Asian countries has been growing steadily and remarkably, following Asian high economic growth. Most of this growth in demand has been and will continue to be met by outside supply. However, even with increased import of methanol from outside of Asia, as a result of this growth, Asian trade volume will be much larger in the coming years. Asian countries must turn their collective attention to making logistics and transportation for methanol and its derivatives more efficient in the Asian region to make better use of existing supply resources. The author reviews current economic growth as his main topic, and explains the forecast of the growth of methanol demand and supply in Asian countries in the near future

    Population aging is the increasing number and proportion of old persons aged 60 years and above in the developing countries and 65 years and above in the developed countries that exceeds 10% of the total population. In Asia, the last decade of the 20th century is marked by significant changes in the age structure due to the process of population aging. The implications of this aging population on the life of Asian countries has to be addressed since demographically the current situation is changing rapidly and there lie the future challenges that have to be answered. Due to the growing size of the elderly population, Asia will need better plans to prevent these elderly groups from turning into the socioeconomically vulnerable group of society. However, many governments are not prepared with effective policies, programs, and services that are particularly designed to care for the elderly. The provision of infrastructure and services, including education, employment, health and housing are necessary steps that need to be taken. Some of the suggested measures include: the Social Safety Net Programs; the implementation of the Association of Southeast Asian Nations Plan of Action on Rural Development and Poverty Eradication; and strengthen volunteerism and the role of private sector in human development. The role of the media in transmitting information concerning policies and programs intended to increase the welfare of the older persons is also very important.

    Burn-up an important parameter during evaluation of the performance of any nuclear fuel. Among the various techniques available, the preferred one for its determination is based on accurate measurement of a suitable fission product monitor and the residual heavy elements. Since isotopes of rare earth elements are generally used as burn-up monitors, conditions were standardized for rapid separation (within 15 minutes) of light rare earths using high performance liquid chromatography based on either anion exchange (Partisil 10 SAX) in methanol-nitric acid medium or by cation exchange on a reverse phase column (Spherisorb 5-ODS-2 or Supelcosil LC-18) dynamically modified with 1-octane sulfonate or camphor-10-sulfonic acid (β). Both these methods were assessed for separation of individual fission product rare earths from their mixtures. A new approach has been examined in detail for rapid assay of neodymium, which appears promising for faster and accurate measurement of burn-up. (author)

    Complementary advances in high pressure research apparatus and techniques make it possible to carry out time-resolved high pressure research using what would customarily be considered static high pressure apparatus. This work specifically explores time-resolved high pressure x-ray diffraction with rapid compression and/or decompression of a sample in a diamond anvil cell. Key aspects of the synchrotron beamline and ancillary equipment are presented, including source considerations, rapid (de)compression apparatus, high frequency imaging detectors, and software suitable for processing large volumes of data. A number of examples are presented, including fast equation of state measurements, compression rate dependent synthesis of metastable states in silicon and germanium, and ultrahigh compression rates using a piezoelectric driven diamond anvil cell

  20. Epidemiology of prostate cancer in Asian countries.

    2018-06-01

    The incidence of prostate cancer has been increasing worldwide in recent years. The GLOBOCAN project showed that prostate cancer was the second most frequently diagnosed cancer and the fifth leading cause of cancer mortality among men worldwide in 2012. This trend has been growing even in Asian countries, where the incidence had previously been low. However, the accuracy of data about incidence and mortality as a result of prostate cancer in some Asian countries is limited. The cause of this increasing trend is multifactorial. One possible explanation is changes in lifestyles due to more Westernized diets. The incidence is also statistically biased by the wide implementation of early detection systems and the accuracy of national cancer registration systems, which are still immature in most Asian countries. Mortality rate decreases in Australia, New Zealand and Japan since the 1990s are possibly due to the improvements in treatment and/or early detection efforts employed. However, this rate is increasing in the majority of other Asian countries. Studies of latent and incidental prostate cancer provide less biased information. The prevalence of latent and incidental prostate cancer in contemporary Japan and Korea is similar to those in Western countries, suggesting the influence of lifestyle changes on carcinogenesis. Many studies reported evidence of both congenital and acquired risk factors for carcinogenesis of prostate cancer. Recent changes in the acquired risk factors might be associated with the increasing occurrence of prostate cancer in Asian countries. This trend could continue, especially in developing Asian countries. © 2018 The Japanese Urological Association.

    The VMEC three-dimensional (3D) MHD equilibrium has been used extensively for designing stellarator experiments and analyzing experimental data in such strongly 3D systems. Recent applications of VMEC include 2D systems such as tokamaks (in particular, the D3D experiment), where application of very small (delB/B ~ 10-3) 3D resonant magnetic field perturbations render the underlying assumption of axisymmetry invalid. In order to facilitate the rapid analysis of such equilibria (for example, for reconstruction purposes), we have undertaken the task of parallelizing the VMEC code (PARVMEC) to produce a scalable and temporally rapidly convergent equilibrium code for use on parallel distributed memory platforms. The parallelization task naturally splits into three distinct parts 1) radial surfaces in the fixed-boundary part of the calculation; 2) two 2D angular meshes needed to compute the Green's function integrals over the plasma boundary for the free-boundary part of the code; and 3) block tridiagonal matrix needed to compute the full (3D) pre-conditioner near the final equilibrium state. Preliminary results show that scalability is achieved for tasks 1 and 3, with task 2 still nearing completion. The impact of this work on the rapid reconstruction of D3D plasmas using PARVMEC in the V3FIT code will be discussed.

    A number of organisations are involved in the field of nuclear medicine education. These include International Atomic Energy Agency (IAEA), World Federation of Nuclear Medicine and Biology (WFNMB), Asia-Oceania Federation of Nuclear Medicine and Biology (AOFNMB), Society of Nuclear Medicine (SNM in USA), European Association of Nuclear Medicine (EANM). Some Universities also have M.Sc courses in Nuclear Medicine. In the Asian Region, an Asian Regional Cooperative Council for Nuclear Medicine (ARCCNM) was formed in 2000, initiated by China, Japan and Korea, with the main aim of fostering the spread of Nuclear Medicine in Asia. The Asian School of Nuclear Medicine (ASNM) was formed in February 2003, with the ARCCNM as the parent body. The Aims of ASNM are: to foster Education in Nuclear Medicine among the Asian countries, particularly the less developed regions; to promote training of Nuclear Medicine Physicians in cooperation with government agencies, IAEA and universities and societies; to assist in national and regional training courses, award continuing medical education (CME) points and provide regional experts for advanced educational programmes; and to work towards awarding of diplomas or degrees in association with recognised universities by distance learning and practical attachments, with examinations. There are 10 to 12 teaching faculty members from each country comprising of physicists, radio pharmacists as well as nuclear medicine physicians. From this list of potential teaching experts, the Vice-Deans and Dean of ASNM would then decide on the 2 appropriate teaching faculty member for a given assignment or a course in a specific country. The educational scheme could be in conjunction with the ARCCNM or with the local participating countries and their nuclear medicine organisations, or it could be a one-off training course in a given country. This teaching faculty is purely voluntary with no major expenses paid by the ASNM; a token contribution could be

    An automated flight test management system (ATMS) and its use to develop a rapid-prototyping flight research facility for artificial intelligence (AI) based flight systems concepts are described. The ATMS provides a flight test engineer with a set of tools that assist in flight planning and simulation. This system will be capable of controlling an aircraft during the flight test by performing closed-loop guidance functions, range management, and maneuver-quality monitoring. The rapid-prototyping flight research facility is being developed at the Dryden Flight Research Facility of the NASA Ames Research Center (Ames-Dryden) to provide early flight assessment of emerging AI technology. The facility is being developed as one element of the aircraft automation program which focuses on the qualification and validation of embedded real-time AI-based systems.

  6. Private Investment in Power Sector in Developing Countries: Lessons from Reforms in Asian and Latin American Countries.

    2007-07-01

    The demand for investment in the electricity sector in the world between 2000 and 2030 is estimated to be USD9.8 trillion. Developing countries would require more than half of this investment. Given the limited fiscal space for public investment, a number of developing countries have undertaken policy initiatives to improve the investment climate for the private sector. The pace, scope, sequencing and outcome of reform process varies across countries. This paper undertakes a comparative evaluation of policy and regulatory reforms in Argentina, Brazil, India, Mexico, PRC and Thailand. The paper concludes that apart from macroeconomic stability, the pace and sequencing of reforms influences private investment in the power sector. Distribution reforms and setting up of an independent regulatory institution reduces risk for investors. A peace-meal approach to reform keeps uncertainties alive for investors and does not translate in significant investment in the sector. (auth)

    Breast cancer is the leading cause of cancer-related deaths in Asia, and in recent years is emerging as the commonest female malignancy in the developing Asian countries, overtaking cancer of the uterine cervix. There have been no studies objectively comparing data and facts relating to breast cancer in the developed, newly developed, and developing Asian countries thus far. This multi-national collaborative study retrospectively compared the demographic, clinical, pathological and outcomes data in breast cancer patients managed at participating breast cancer centers in India, Malaysia and Hong Kong. Data, including those on the availability of breast screening, treatment facilities and outcomes from other major cancer centers and cancer registries of these countries and from other Asian countries were also reviewed. Despite an increasing trend, the incidence of breast cancer is lower, yet the cause-specific mortality is significantly higher in developing Asian countries compared with developed countries in Asia and the rest of the world. Patients are about one decade younger in developing countries than their counterparts in developed nations. The proportions of young patients (women and the clinical picture are different from those of average patients managed elsewhere in the world. Owing to lack of awareness, lack of funding, lack of infrastructure, and low priority in public health schemes, breast cancer screening and early detection have not caught up in these under-privileged societies. The inadequacies of health care infrastructures and standards, sociocultural barriers, economic realities, illiteracy, and the differences in the clinical and pathological attributes of this disease in Asian women compared with the rest of the world together result in a different spectrum of the disease. Better socioeconomic conditions, health awareness, and availability of breast cancer screening in developed Asian countries seem to be the major causes of a favorable clinical

    Full Text Available This article considers the problem of ontology security through Asian educational discourse, which is structurally determined by the process of moral self-improvement. Considered are trends in improving the management of educational system by developing the culture of quality, which is considered as the next stage of the Asian education systems development after the “quality of education” stage. We suggest an approach for assessing the vitality of educational process and its product based on monitoring trainees’ aptitudes system and school capabilities in developing and maintaining this system. In this study we refer to the concept of vitality and viability when describing the general theory of viability in connection with the core principles of Asian educational discourse. We outline main trends in the development of modern educational system in Asian university given the process of globalization and its impact on educational reforms in the Asia-Pacific region. Thus, the category of education quality in Asian system of higher education and narrative monitoring of Chinese students’ cognitive structures viability at Altai State University are introduced.

    The Asian monsoon system is an important tipping element in Earth's climate with a large impact on human societies in the past and present. In light of the potentially severe impacts of present and future anthropogenic climate change on Asian hydrology, it is vital to understand the forcing mechanisms of past climatic regime shifts in the Asian monsoon domain. Here we use novel recurrence network analysis techniques for detecting episodes with pronounced non-linear changes in Holocene Asian monsoon dynamics recorded in speleothems from caves distributed throughout the major branches of the Asian monsoon system. A newly developed multi-proxy methodology explicitly considers dating uncertainties with the COPRA (COnstructing Proxy Records from Age models) approach and allows for detection of continental-scale regime shifts in the complexity of monsoon dynamics. Several epochs are characterised by non-linear regime shifts in Asian monsoon variability, including the periods around 8.5-7.9, 5.7-5.0, 4.1-3.7, and 3.0-2.4 ka BP. The timing of these regime shifts is consistent with known episodes of Holocene rapid climate change (RCC) and high-latitude Bond events. Additionally, we observe a previously rarely reported non-linear regime shift around 7.3 ka BP, a timing that matches the typical 1.0-1.5 ky return intervals of Bond events. A detailed review of previously suggested links between Holocene climatic changes in the Asian monsoon domain and the archaeological record indicates that, in addition to previously considered longer-term changes in mean monsoon intensity and other climatic parameters, regime shifts in monsoon complexity might have played an important role as drivers of migration, pronounced cultural changes, and the collapse of ancient human societies.

    Full Text Available In many cases evaluation of chlorophyll and nitrogen content in plants need to destructive methods, more time and organic solvents. Application of chlorophyll meters save time and resources. The aim of this study was estimating of chlorophyll and nitrogen content in Asian pear leaves using non-destructive method and rapid quantification of chlorophyll by chlorophyll content meter (CCM-200. This study was conducted on 8 years old Asian pear trees during June 2008 in Tehran, Iran. To develop our regression model, the chlorophyll meter data were correlated with extracted chlorophyll and nitrogen content data obtained from DMSO and Kejeldal methods, respectively. The results showed that, there was positive and linear correlation between CCM-200 data and chlorophyll a (R�=0.7183, chlorophyll b (R�=0.8523, total chlorophyll (R�=0.90, and total nitrogen content (R�=0.76 in Asian pear leaves. Thus, it can be concluded that, CCM-200 can be used in order to predict both chlorophyll and nitrogen content in Asian pear leaves.

    This article highlights contraceptive issues in Asia, home to some 700 million adolescents. It starts with a description of the socio-cultural milieu of adolescents in South and Southeast Asia, their knowledge and use of contraceptives, the myriad barriers to access, and the many innovative programs to broaden contraceptive availability. The reproductive health needs of adolescents in poor countries cannot be solved by merely supplying them with contraceptives--these needs can only be fully addressed in the context of gender equality, poverty alleviation and the conviction that investing in the reproductive health of adolescents is a most urgent priority. Investing in the reproductive health of adolescents will have an impact not only on birth and abortion rates, maternal health, and the spread of STI/HIV but also on the demographics and economic development of the region--and beyond.

    The prevalence of chronic kidney disease (CKD) in Asia is expected to increase along with increases of hypertension and diabetes. Most cases are not treated and progress to end-stage renal disease (ESRD) with an increased risk for cardiovascular complications. Renal replacement therapies are so expensive that most ESRD patients die without treatment. Thus, countermeasures against early stages of CKD are urgently needed. Nevertheless, basic information for CKD has not been reported in Vietnam. We conducted a survey of CKD in 8,505 inhabitants aged >40 years in Vietnam. Subjects with abnormal urinary findings were further examined, including serum creatinine levels. In this study, CKD was defined as development of efficient management systems suitable for Asia.

    Full Text Available Abstract Background Instruments to measure mental health and well-being are largely developed and often used within Western populations and this compromises their validity in other cultures. A previous qualitative study in Singapore demonstrated the relevance of spiritual and religious practices to mental health, a dimension currently not included in exiting multi-dimensional measures. The objective of this study was to develop a self-administered measure that covers all key and culturally appropriate domains of mental health, which can be applied to compare levels of mental health across different age, gender and ethnic groups. We present the item reduction and validation of the Positive Mental Health (PMH instrument in a community-based adult sample in Singapore. Methods Surveys were conducted among adult (21-65 years residents belonging to Chinese, Malay and Indian ethnicities. Exploratory and confirmatory factor analysis (EFA, CFA were conducted and items were reduced using item response theory tests (IRT. The final version of the PMH instrument was tested for internal consistency and criterion validity. Items were tested for differential item functioning (DIF to check if items functioned in the same way across all subgroups. Results: EFA and CFA identified six first-order factor structure (General coping, Personal growth and autonomy, Spirituality, Interpersonal skills, Emotional support, and Global affect under one higher-order dimension of Positive Mental Health (RMSEA = 0.05, CFI = 0.96, TLI = 0.96.

    Despite their wealth and modern road systems, traffic injury rates in Middle Eastern countries are generally higher than those in Western countries. The authors examined traffic injuries in Qatar during 2000–2010, a period of rapid population growth, focusing on the impact of speed control cameras installed in 2007 on overall injury rates and mortality. During the period 2000–2006, prior to camera installation, the mean (SD) vehicular injury death rate per 100 000 was 19.9±4.1. From 2007 to 2010, the mean (SD) vehicular death rates were significantly lower: 14.7±1.5 (p=0.028). Non-fatal severe injury rates also declined, but mild injury rates increased, perhaps because of increased traffic congestion and improved notification. It is possible that speed cameras decreased speeding enough to affect the death rate, without affecting overall injury rates. These data suggest that in a rapidly growing Middle Eastern country, photo enforcement (speed) cameras can be an important component of traffic control, but other measures will be required for maximum impact.

    We have developed a rapid radiochemical procedure for the isolation and purification of /sup 235m/U (t/sub 1/2/ = 26 minutes) from 239 Pu samples up to 250 mg. Purpose of developing the procedure was to measure the thermal neutron fission cross section of the isomeric meta state of 235 U. We used rapid small-scale anion exchange columns that absorbed uranium in concentrated HBr but did not absorb plutonium. Uranium was easily eluted with very dilute HF. The separation time required 25 to 35 minutes. We were able to attain a separation factor of uranium from plutonium of approximately 1 x 10 10 with samples ranging from 1 x 10 10 to 3 x 10 11 . The ratio of the fission cross sections for the meta to ground state was measured to be 1.42. 4 figs., 1 tab

    Earthquakes are among the most horrible events of nature due to unexpected occurrence, for which no spiritual means are available for protection. The only way of preserving life and property is applying earthquake-resistant construction methods. Ancient Greek architects of public buildings applied steel clamps embedded in lead casing to hold together columns and masonry walls during frequent earthquakes in the Aegean region. Elastic steel provided strength, while plastic lead casing absorbed minor shifts of blocks without fracturing rigid stone. Romans invented concrete and built all sizes of buildings as a single, unflexible unit. Masonry surrounding and decorating concrete core of the wall did not bear load. Concrete resisted minor shaking, yielding only to forces higher than fracture limits. Roman building traditions survived the Dark Ages and 12th century Crusader castles erected in earthquake-prone Syria survive until today in reasonably good condition. Concrete and steel clamping persisted side-by-side in the Roman Empire. Concrete was used for cheap construction as compared to building of masonry. Applying lead-encased steel increased costs, and was avoided whenever possible. Columns of the various forums in Italian Pompeii mostly lack steel fittings despite situated in well-known earthquake-prone area. Whether frequent recurrence of earthquakes in the Naples region was known to inhabitants of Pompeii might be a matter of debate. Seemingly the shock of the AD 62 earthquake was not enough to apply well-known protective engineering methods throughout the reconstruction of the city before the AD 79 volcanic catastrophe. An independent engineering tradition developed on the island of Java (Indonesia). The mortar-less construction technique of 8-9th century Hindu masonry shrines around Yogyakarta would allow scattering of blocks during earthquakes. To prevent dilapidation an intricate mortise-and-tenon system was carved into adjacent faces of blocks. Only the

    Ise, Tadashi; Hamamatsu, Takeo; Imoto, Teruhiko; Nogami, Mitsuzo; Nakahori, Shinsuke

    The effects of annealing a rapidly-quenched hydrogen-absorbing alloy with a stoichiometric ratio of 4.76 were investigated concerning its hydrogen-absorbing properties, crystal structure and electrochemical characteristics. Annealing at 1073 K homogenized the alloy microstructure and flattened its plateau slope in the P-C isotherms. However, annealing at 1273 K segregated a second phase rich in rare earth elements, increased the hydrogen-absorbing pressure and decreased the hydrogen-absorbing capacity. As the number of charge-discharge cycles increases, the particle size distribution of the rapidly-quenched alloy became broad due to partial pulverization. However, particle size distribution of the rapidly-quenched, annealed, alloy was sharp, since the annealing homogenized the microstructure, thereby improving the cycle characteristics. A high-capacity rectangular nickel metal hydride battery using a rapidly-quenched, annealed, surface-treated alloy for the negative electrode and an active material coated with cobalt compound containing sodium for the positive electrode was developed. The capacity of the resulting battery was 30% greater than that of a conventional battery.

  7. Asian Citrus Psyllid Expression Profiles Suggest Candidatus Liberibacter Asiaticus-Mediated Alteration of Adult Nutrition and Metabolism, and of Nymphal Development and Immunity.

    Full Text Available The Asian citrus psyllid (ACP Diaphorina citri Kuwayama (Hemiptera: Psyllidae is the insect vector of the fastidious bacterium Candidatus Liberibacter asiaticus (CLas, the causal agent of citrus greening disease, or Huanglongbing (HLB. The widespread invasiveness of the psyllid vector and HLB in citrus trees worldwide has underscored the need for non-traditional approaches to manage the disease. One tenable solution is through the deployment of RNA interference technology to silence protein-protein interactions essential for ACP-mediated CLas invasion and transmission. To identify psyllid interactor-bacterial effector combinations associated with psyllid-CLas interactions, cDNA libraries were constructed from CLas-infected and CLas-free ACP adults and nymphs, and analyzed for differential expression. Library assemblies comprised 24,039,255 reads and yielded 45,976 consensus contigs. They were annotated (UniProt, classified using Gene Ontology, and subjected to in silico expression analyses using the Transcriptome Computational Workbench (TCW (http://www.sohomoptera.org/ACPPoP/. Functional-biological pathway interpretations were carried out using the Kyoto Encyclopedia of Genes and Genomes databases. Differentially expressed contigs in adults and/or nymphs represented genes and/or metabolic/pathogenesis pathways involved in adhesion, biofilm formation, development-related, immunity, nutrition, stress, and virulence. Notably, contigs involved in gene silencing and transposon-related responses were documented in a psyllid for the first time. This is the first comparative transcriptomic analysis of ACP adults and nymphs infected and uninfected with CLas. The results provide key initial insights into host-parasite interactions involving CLas effectors that contribute to invasion-virulence, and to host nutritional exploitation and immune-related responses that appear to be essential for successful ACP-mediated circulative, propagative CLas

    The concept of quality by design (QbD) is widely applied in the process development of pharmaceuticals. However, the additional cost and time have caused some resistance about QbD implementation. To show a possible solution, this work proposed a rapid process development method, which used direct analysis in real time mass spectrometry (DART-MS) as a process analytical technology (PAT) tool for studying the chromatographic process of Ginkgo biloba L., as an example. The breakthrough curves were fast determined by DART-MS at-line. A high correlation coefficient of 0.9520 was found between the concentrations of ginkgolide A determined by DART-MS and HPLC. Based on the PAT tool, the impacts of process parameters on the adsorption capacity were discovered rapidly, which showed a decreased adsorption capacity with the increase of the flow rate. This work has shown the feasibility and advantages of integrating PAT into QbD implementation for rapid process development. Copyright © 2014 Elsevier B.V. All rights reserved.

    Neonatal animals are generally very susceptible to infection with bacterial pathogens. However, we recently reported that neonatal mice are highly resistant to orogastric infection with Yersinia enterocolitica. Here, we show that proinflammatory responses greatly exceeding those in adults arise very rapidly in the mesenteric lymph nodes (MLN) of neonates. High-level induction of proinflammatory gene expression occurred in the neonatal MLN as early as 18 h postinfection. Marked innate phagocyte recruitment was subsequently detected at 24 h postinfection. Enzyme-linked immunosorbent spot assay (ELISPOT) analyses indicated that enhanced inflammation in neonatal MLN is contributed to, in part, by an increased frequency of proinflammatory cytokine-secreting cells. Moreover, both CD11b+ and CD11b− cell populations appeared to play a role in proinflammatory gene expression. The level of inflammation in neonatal MLN was also dependent on key bacterial components. Y. enterocolitica lacking the virulence plasmid failed to induce innate phagocyte recruitment. In contrast, tumor necrosis factor alpha (TNF-α) protein expression and neutrophil recruitment were strikingly higher in neonatal MLN after infection with a yopP-deficient strain than with wild-type Y. enterocolitica, whereas only modest increases occurred in adults. This hyperinflammatory response was associated with greater colonization of the spleen and higher mortality in neonates, while there was no difference in mortality among adults. This model highlights the dynamic levels of inflammation in the intestinal lymphoid tissues and reveals the protective (wild-type strain) versus harmful (yopP-deficient strain) consequences of inflammation in neonates. Moreover, these results reveal that the neonatal intestinal lymphoid tissues have great potential to rapidly mobilize innate components in response to infection with bacterial enteropathogens.

  16. Comparative Studies on Vehicle Related Policies for Air Pollution Reduction in Ten Asian Countries

    Directory of Open Access Journals (Sweden)

    Keiko Hirota

    2010-01-01

    Full Text Available Asian countries are facing major air pollution problems due to rapid economic growth, urbanization and motorization. Mortality and respiratory diseases caused by air pollution are believed to be endemic in major cities of these countries. Regulations and standards are the first requirement for reducing emissions from both fixed and mobile sources. This paper emphasizes monitoring problems such as vehicle registration systems, inspection and maintenance (I/M systems and fuel quality monitoring systems for vehicles in use. Monitoring problems in developing countries share similar characteristics such as a weakness in government initiatives and inadequate operation of government agencies, which results from a lack of human resources and availability of adequate facilities. Finally, this paper proposes a method to assure air quality improvements under the different shares of emission regulations in these Asian countries and introduces an example of an evaluation method based on a policy survey to improve air quality.

The development of a one-step, single tube, rapid, and multiplex reverse transcription polymerase chain reaction (M-RT-PCR for simultaneous detection and typing of dengue virus using serotype specific primers during acute phase of illness is reported. Results An optimal assay condition with zero background was established having no cross-reaction with closely related members of flavivirus (Japanese encephalitis, West Nile, Yellow fever and alphavirus (Chikungunya. The feasibility of M-RT-PCR assay for clinical diagnosis was validated with 620 acute phase dengue patient sera samples of recent epidemics in India. The comparative evaluation vis a vis conventional virus isolation revealed higher sensitivity. None of the forty healthy serum samples screened in the present study revealed any amplification, thereby establishing specificity of the reported assay for dengue virus only. Conclusion These findings clearly suggested that M-RT-PCR assay reported in the present study is the rapid and cost-effective method for simultaneous detection as well as typing of the dengue virus in acute phase patient serum samples. Thus, the M-RT-PCR assay developed in this study will serve as a very useful tool for rapid diagnosis and typing of dengue infections in endemic areas.

    Full Text Available Abstract Background The recent dramatic decline in dihydroartemisinin-piperaquine (DHA-PPQ efficacy in northwestern Cambodia has raised concerns about the rapid spread of piperaquine resistance just as DHA-PPQ is being introduced as first-line therapy in neighbouring countries. Methods Ex vivo parasite susceptibilities were tracked to determine the rate of progression of DHA, PPQ and mefloquine (MQ resistance from sentinel sites on the Thai–Cambodian and Thai–Myanmar borders from 2010 to 2015. Immediate ex vivo (IEV histidine-rich protein 2 (HRP-2 assays were used on fresh patient Plasmodium falciparum isolates to determine drug susceptibility profiles. Results IEV HRP-2 assays detected the precipitous emergence of PPQ resistance in Cambodia beginning in 2013 when 40 % of isolates had an IC90 greater than the upper limit of prior years, and this rate doubled to 80 % by 2015. In contrast, Thai–Myanmar isolates from 2013 to 14 remained PPQ-sensitive, while northeastern Thai isolates appeared to have an intermediate resistance profile. The opposite trend was observed for MQ where Cambodian isolates appeared to have a modest increase in overall sensitivity during the same period, with IC50 declining to median levels comparable to those found in Thailand. A significant association between increased PPQ IC50 and IC90 among Cambodian isolates with DHA-PPQ treatment failure was observed. Nearly all Cambodian and Thai isolates were deemed artemisinin resistant with a >1 % survival rate for DHA in the ring-stage assay (RSA, though there was no correlation among isolates to indicate cross-resistance between PPQ and artemisinins. Conclusions Clinical DHA-PPQ failures appear to be associated with declines in the long-acting partner drug PPQ, though sensitivity appears to remain largely intact for now in western Thailand. Rapid progression of PPQ resistance associated with DHA-PPQ treatment failures in northern Cambodia limits drugs of choice in

  1. Towards the development of rapid screening techniques for shale gas core properties

    2013-04-01

    Shale gas has been produced for many years in the U.S.A. and forms around 8% of total their natural gas production. Recent testing for gas on the Fylde Coast in Lancashire UK suggests there are potentially large reserves which could be exploited. The increasing significance of shale gas has lead to the need for deeper understanding of shale behaviour. There are many factors which govern whether a particular shale will become a shale gas resource and these include: i) Organic matter abundance, type and thermal maturity; ii) Porosity-permeability relationships and pore size distribution; iii) Brittleness and its relationship to mineralogy and rock fabric. Measurements of these properties require sophisticated and time consuming laboratory techniques (Josh et al 2012), whereas rapid screening techniques could provide timely results which could improve the efficiency and cost effectiveness of exploration. In this study, techniques which are portable and provide rapid on-site measurements (X-ray Fluorescence (XRF) and Infra-red (IR) spectroscopy) have been calibrated against standard laboratory techniques (Rock-Eval 6 analyser-Vinci Technologies) and Powder whole-rock XRD analysis was carried out using a PANalytical X'Pert Pro series diffractometer equipped with a cobalt-target tube, X'Celerator detector and operated at 45kV and 40mA, to predict properties of potential shale gas material from core material from the Bowland shale Roosecote, south Cumbria. Preliminary work showed that, amongst various mineralogical and organic matter properties of the core, regression models could be used so that the total organic carbon content could be predicted from the IR spectra with a 95 percentile confidence prediction error of 0.6% organic carbon, the free hydrocarbons could be predicted with a 95 percentile confidence prediction error of 0.6 mgHC/g rock, the bound hydrocarbons could be predicted with a 95 percentile confidence prediction error of 2.4 mgHC/g rock, mica content

    Herpesvirus of turkeys (HVT) has been successfully used as live vaccine against Marek's disease (MD) worldwide for more than 40 years either alone or in combination with other serotypes. HVT is also widely used as a vector platform for generation of recombinant vaccines against a number of avian diseases such as infectious bursal disease (IBD), Newcastle disease (ND) and avian influenza (AI) using conventional recombination methods or recombineering tools on cloned viral genomes. In the present study, we describe the application of CRISPR/Cas9-based genome editing as a rapid and efficient method of generating HVT recombinants expressing VP2 protein of IBDV. This approach offers an efficient method to introduce other viral antigens into the HVT genome for rapid development of recombinant vaccines. Copyright © 2018 The Pirbright Institute.

    2006-02-01

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

    With the increase in international human and material exchanges, contagious and infectious epidemics are occurring. One of the effective methods of epidemic inhibition is the rapid development and supply of vaccines. Considering the safety of the brain during vaccine development is very important. However, manuals for brain safety assays for new vaccines are not uniform or effective globally. Therefore, the aim of this study is to establish a positive-control protocol for an effective brain safety test to enhance rapid vaccine development. The blood-brain barrier's tight junctions provide selective defense of the brain; however, it is possible to destroy these important microstructures by administering lipopolysaccharides (LPSs), thereby artificially increasing the permeability of brain parenchyma. In this study, test conditions are established so that the degree of brain penetration or brain destruction of newly developed vaccines can be quantitatively identified. The most effective conditions were suggested by measuring time-dependent expressions of tight junction biomarkers (zonula occludens-1 [ZO-1] and occludin) in two types of mice (C57BL/6 and ICR) following exposure to two types of LPS ( Salmonella and Escherichia ). In the future, we hope that use of the developed positive-control protocol will help speed up the determination of brain safety of novel vaccines.

    Using 108 petroleum contaminated soil samples, this pilot study proposed a new analytical approach of combining visible near-infrared diffuse reflectance spectroscopy (VisNIR DRS) and portable X-ray fluorescence spectrometry (PXRF) for rapid and improved quantification of soil petroleum contamination. Results indicated that an advanced fused model where VisNIR DRS spectra-based penalized spline regression (PSR) was used to predict total petroleum hydrocarbon followed by PXRF elemental data-based random forest regression was used to model the PSR residuals, it outperformed (R{sup 2} = 0.78, residual prediction deviation (RPD) = 2.19) all other models tested, even producing better generalization than using VisNIR DRS alone (RPD's of 1.64, 1.86, and 1.96 for random forest, penalized spline regression, and partial least squares regression, respectively). Additionally, unsupervised principal component analysis using the PXRF + VisNIR DRS system qualitatively separated contaminated soils from control samples. Capsule: Fusion of PXRF elemental data and VisNIR derivative spectra produced an optimized model for total petroleum hydrocarbon quantification in soils. - Highlights: • PXRF elemental data and VisNIR DRS spectra were correlated to soil TPH. • VisNIR + PSR was used to predict TPH followed by PXRF + RF to predict the residuals. • The fused model produced better results than other multivariate models tested.

    To assess the validity of a quick assessment instrument (10 minutes) for assessing personality status, the Rapid Personality Assessment Schedule (PAS-R). The PAS-R was evaluated in psychotic patients recruited in one of the centres involved in a multicentre randomised controlled trial of intensive vs standard case management (the UK700 case management trial). Patients were assessed using both a full version of the PAS (PAS-I - ICD version) and the PAS-R. The weighted kappa statistic was used to gauge the (criterion-related) validity of the PAS-R using the PAS-I as the gold standard. Both measure code personality status using a four-point rating of severity in addition to recording individual categories of personality disorder. One hundred fifty-five (77%) of 201 patients recruited were assessed with both instruments. The weighted kappa statistic was 0.31, suggesting only moderate agreement between the PAS-I and PAS-R instruments under the four-point rating format, and 0.39 for the dichotomous personality disorder/no disorder separation. The sensitivity (64%) and specificity (82%) of the PAS-R in predicting PAS-I personality disorder were as satisfactory as for other screening instruments but still somewhat disappointing, and the PAS-R had an overall diagnostic accuracy of 78%. The PAS-R is a quick and rough method of detecting personality abnormality but is not a substitute for a fuller assessment.

    Giardia lamblia is a zoonotic flagellate protozoan in the intestine of human and many mammals including dogs. To assess a threat of dog-derived G. lamblia to humans, the common dog-derived G. lamblia assemblages A, C, and D were genotyped by high-resolution melting (HRM) technology. According to β-giardin gene sequence, the qPCR-HRM primers BG5 and BG7 were designed. A series of experiments on the stability, sensitivity, and accuracy of the HRM method were also tested. Results showed that the primers BG5 and BG7 could distinguish among three assemblages A, C, and D, which Tm value differences were about 1 °C to each other. The melting curves of intra-assay reproducibility were almost coincided, and those of inter-assay reproducibility were much the same shape. The lowest detection concentration was about 5 × 10(-6)-ng/μL sample. The genotyping results from 21 G. lamblia samples by the HRM method were in complete accordance with sequencing results. It is concluded that the HRM genotyping method is rapid, stable, specific, highly sensitive, and suitable for clinical detection and molecular epidemiological survey of dog-derived G. lamblia.

    Full Text Available Polyphenols are secondary metabolites of plants, which are responsible for prevention of many diseases. Polyvinylpolypyrrolidone (PVPP has a high affinity towards polyphenols. This method involves the use of PVPP column to remove polyphenols under centrifugal force. Standards of gallic acid, epigallocatechin gallate, vanillin, and tea extracts (Camellia sinensis were used in this study. PVPP powder was packed in a syringe with different quantities. The test samples were layered over the PVPP column and subjected to centrifugation. Supernatant was tested for the total phenol content. The presence of phenolic compounds and caffeine was screened by HPLC and measuring the absorbance at 280. The antioxidant capacity of standards and tea extracts was compared with the polyphenol removed fractions using DPPH scavenging assay. No polyphenols were found in polyphenolic standards or tea extracts after PVPP treatment. The method described in the present study to remove polyphenols is simple, inexpensive, rapid, and efficient and can be employed to investigate the contribution of polyphenols present in natural products to their biological activity.

    During the last past decades, there is an increasing number of studies about estrogenic activities of the environmental pollutants on amphibians and many determination methods have been proposed. However, these determination methods are time-consuming and expensive, and a rapid and simple method to screen and test the chemicals for estrogenic activities to amphibians is therefore imperative. Herein is proposed a new decision tree formulated not only with physicochemical parameters but also a biological parameter that was successfully used to screen estrogenic activities of the chemicals on amphibians. The biological parameter, CDOCKER interaction energy (Ebinding ) between chemicals and the target proteins was calculated based on the method of molecular docking, and it was used to revise the decision tree formulated by Hong only with physicochemical parameters for screening estrogenic activity of chemicals in rat. According to the correlation between Ebinding of rat and Xenopus laevis, a new decision tree for estrogenic activities in Xenopus laevis is finally proposed. Then it was validated by using the randomly 8 chemicals which can be frequently exposed to Xenopus laevis, and the agreement between the results from the new decision tree and the ones from experiments is generally satisfactory. Consequently, the new decision tree can be used to screen the estrogenic activities of the chemicals, and combinational use of the Ebinding and classical physicochemical parameters can greatly improves Hong's decision tree.

    The Roaring Fork Transit Authority (RFTA) and its VelociRFTA Bus Rapid Transit (BRT) program are unique in many ways. For example, VelociRFTA was the first rural BRT system in the United States and the operational environment of the VelociRFTA BRT is one of the most severe in the country, with extreme winter temperatures and altitudes close to 8,000 feet. RFTA viewed high altitude operation as the most challenging characteristic when it began considering the use of natural gas. RFTA is the second-largest public transit system in Colorado behind Denver's Regional Transportation District (RTD), and it is one of the largest rural public transit systems in the country. In 2013, RFTA accepted delivery of 22 new compressed natural gas (CNG) buses that went into service after completion of maintenance and refueling facilities earlier that year. This paper examines the lessons learned from RFTA's experience of investigating--and ultimately choosing--CNG for their new BRT program and focuses on the unique environment of RFTA's BRT application; the decision process to include CNG fueling in the project; unforeseen difficulties encountered in the operation of CNG buses; public perception; cost comparison to competing fuels; and considerations for indoor fueling facilities and project funding.

    Ballast water is a principal pathway for the introduction of pathogens and non-indigenous species to ports worldwide. The International Maritime Organization (IMO) and the United States Coast Guard (USCG) have adopted ballast water management regulations that require, e.g., the installation of shipboard ballast water management systems (BWMS). Rapid and simple analytical methods are needed to monitor whether ballast water disinfection ensures compliance with the discharge standards. In this study laboratory and full scale land-based testing was used to investigate the suitability of an adenosine triphosphate (ATP) assay for quantifying living organisms (≥ 10 and land-based testing the ATP assay also showed a good correlation with the presence of living natural plankton cells in control samples, but the ATP concentration (137 pg mL- 1) was much lower than the ATP guideline. The low ATP concentration in natural plankton cells may reflect a decline in their biological activity because of extended exposure to dark conditions. Although our results need further validation, the ATP assay is a suitable tool for monitoring compliance of ballast water treatment.

    Since the introduction of standardized nematode toxicity assays by the American Society for Testing and Materials (ASTM) and International Organization for Standardization (ISO), many studies have reported their use. Given that the currently used standardized nematode toxicity assays have certain limitations, in this study, we examined the use of a novel nematode offspring counting assay for evaluating soil ecotoxicity based on a previous soil-agar isolation method used to recover live adult nematodes. In this new assay, adult Caenorhabditis elegans were exposed to soil using a standardized toxicity assay procedure, and the resulting offspring in test soils attracted by a microbial food source in agar plates were counted. This method differs from previously used assays in terms of its endpoint, namely, the number of nematode offspring. The applicability of the bioassay was demonstrated using metal-spiked soils, which revealed metal concentration-dependent responses, and with 36 field soil samples characterized by different physicochemical properties and containing various metals. Principal component analysis revealed that texture fraction (clay, sand, and silt) and electrical conductivity values were the main factors influencing the nematode offspring counting assay, and these findings warrant further investigation. The nematode offspring counting assay is a rapid and simple process that can provide multi-directional toxicity assessment when used in conjunction with other standard methods.

    2012-01-01

    The Rapid Office Strain Assessment (ROSA) was designed to quickly quantify risks associated with computer work and to establish an action level for change based on reports of worker discomfort. Computer use risk factors were identified in previous research and standards on office design for the chair, monitor, telephone, keyboard and mouse. The risk factors were diagrammed and coded as increasing scores from 1 to 3. ROSA final scores ranged in magnitude from 1 to 10, with each successive score representing an increased presence of risk factors. Total body discomfort and ROSA final scores for 72 office workstations were significantly correlated (R = 0.384). ROSA final scores exhibited high inter- and intra-observer reliability (ICCs of 0.88 and 0.91, respectively). Mean discomfort increased with increasing ROSA scores, with a significant difference occurring between scores of 3 and 5 (out of 10). A ROSA final score of 5 might therefore be useful as an action level indicating when immediate change is necessary. ROSA proved to be an effective and reliable method for identifying computer use risk factors related to discomfort. Copyright © 2011 Elsevier Ltd and The Ergonomics Society. All rights reserved.

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

    Kushniruk, Andre; Borycki, Elizabeth

    2017-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Can-Xing Duan

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

    Asians increasingly seek non-surgical facial esthetic treatments, especially at younger ages. Published recommendations and clinical evidence mostly reference Western populations, but Asians differ from them in terms of attitudes to beauty, structural facial anatomy, and signs and rates of aging. A thorough knowledge of the key esthetic concerns and requirements for the Asian face is required to strategize appropriate facial esthetic treatments with botulinum toxin and hyaluronic acid (HA) fillers. The Asian Facial Aesthetics Expert Consensus Group met to develop consensus statements on concepts of facial beauty, key esthetic concerns, facial anatomy, and aging in Southeastern and Eastern Asians, as a prelude to developing consensus opinions on the cosmetic facial use of botulinum toxin and HA fillers in these populations. Beautiful and esthetically attractive people of all races share similarities in appearance while retaining distinct ethnic features. Asians between the third and sixth decades age well compared with age-matched Caucasians. Younger Asians' increasing requests for injectable treatments to improve facial shape and three-dimensionality often reflect a desire to correct underlying facial structural deficiencies or weaknesses that detract from ideals of facial beauty. Facial esthetic treatments in Asians are not aimed at Westernization, but rather the optimization of intrinsic Asian ethnic features, or correction of specific underlying structural features that are perceived as deficiencies. Thus, overall facial attractiveness is enhanced while retaining esthetic characteristics of Asian ethnicity. Because Asian patients age differently than Western patients, different management and treatment planning strategies are utilized.

  7. Sexuality and human rights: an Asian perspective.

    Science.gov (United States)

    Laurent, Erick

    2005-01-01

    In Asia, the lesbian and gay rights movements are clearly dominated by activists, who tend to think in terms of a binary opposition (homo- vs hetero-) and clear-cut categories. Based on "Western patterns," the approach is practical, the arguments based on minority rights. "Coming out" is often perceived as a "white model" bringing more problems than real freedom. On the contrary, "Asian values" put the emphasis on family and social harmony, often in contradiction to what is pictured as "lesbian and gay rights." Homophobia follows very subtle ways in Asian countries. Asian gays have to negotiate their freedom, lifestyle and identities in an atmosphere of heterosexism, and not the endemic violent homophobia prevalent in many western countries. In Asia, one's identity relates to one's position in the group and sexuality plays a relatively insignificant role in its cultural construction. That Asian gays often marry and have children shows the elasticity their sexual identity encompasses. Fluidity of sexuality does not really match the Western approach in terms of essentialist categories that have a right to exist. Most Asian societies can be thought of as "tolerant" as long as homosexuality remains invisible. Procreative sexuality can be seen as a social duty, and heterosexual marriage is often not considered incompatible with a "homosexual life." The development of the Internet has even facilitated the encounters while allowing secrecy. Unfortunately, the traditional figures of transgender and transvestites have often been separated from the gay liberation movement.

  8. Design guidelines for rapid and simple context-aware mobile application development – an android case study

    2015-11-01

    Full Text Available Presenting a context-aware service and information is a key aspect of ubiquitous computing, but development of such applications is quite complicated. Context-aware applications should be able to obtain raw data fromsensors, create highlevel context information, detect the user’s situation, and adapt the behavior of the application to the recognized situation . These complexities caused to reduce the impact of context -awareness in mobile computing while sensors of smartphones have made huge potential for developing context aware mobile applications. In this paper, we explain some guidelines to overcome the existing obstacles by separating the context -aware application layers and make a loosely coupled connection between them. These guidelines will bring easy and rapid development, reusability of the code and flexibility for developers. Finally, we provide a case study example in the Android platform to demonstrate how the guidelines can be used in a real application.

    Hallmark features of neural circuit development include early exuberant innervation followed by competition and pruning to mature innervation topography. Several neural systems, including the neuromuscular junction and climbing fiber innervation of Purkinje cells, are models to study neural development in part because they establish a recognizable endpoint of monoinnervation of their targets and because the presynaptic terminals are large and easily monitored. We demonstrate here that calyx of Held (CH) innervation of its target, which forms a key element of auditory brainstem binaural circuitry, exhibits all of these characteristics. To investigate CH development, we made the first application of serial block-face scanning electron microscopy to neural development with fine temporal resolution and thereby accomplished the first time series for 3D ultrastructural analysis of neural circuit formation. This approach revealed a growth spurt of added apposed surface area (ASA)>200 μm2/d centered on a single age at postnatal day 3 in mice and an initial rapid phase of growth and competition that resolved to monoinnervation in two-thirds of cells within 3 d. This rapid growth occurred in parallel with an increase in action potential threshold, which may mediate selection of the strongest input as the winning competitor. ASAs of competing inputs were segregated on the cell body surface. These data suggest mechanisms to select "winning" inputs by regional reinforcement of postsynaptic membrane to mediate size and strength of competing synaptic inputs.

    Schwabl, Hubert; Palacios, Maria G; Martin, Thomas E

    2007-08-01

    Greater offspring predation favors evolution of faster development among species. We hypothesized that greater offspring predation exerts selection on mothers to increase levels of anabolic androgens in egg yolks to achieve faster development. Here, we tested whether (1) concentrations of yolk androgens in passerine species were associated with offspring predation and (2) embryo and nestling development rates were associated with yolk androgen concentrations. We examined three androgens that increase in potency along the synthesis pathway: androstenedione (A(4)) to testosterone (T) to 5 alpha -dihydrotestosterone (5 alpha -DHT). Concentrations of none of these steroids were related to clutch size; only A(4) was allometrically related to egg volume. Species that experience greater predation showed higher yolk concentrations of T and 5 alpha -DHT. Higher concentrations of T and particularly 5 alpha -DHT were strongly correlated with faster development during the embryo period and less so during the nestling period. Development rates were most strongly correlated with 5 alpha -DHT, suggesting that potency increases along the androgen synthesis pathway and that effects are mediated by the androgen receptor pathway. These results are consistent with the hypothesis that selection for faster development by time-dependent offspring mortality may be achieved epigenetically by varying embryo exposure to maternal anabolic steroids.

    Through annual consultation with its customers, Enbridge develops a supply and demand forecast which forms the basis for the company's development. It is complex to develop the appropriate pipeline infrastructure to support resource development, based on the significant forecast growth in supply in Alberta from oil sands and the limited traditional markets. The largest crude oil pipeline serving the oil sands industry in Alberta is owned and operated by Enbridge. The first customer was Suncor, followed by PetroCanada and EnCana. In 2002, a pipeline concept was developed by Enbridge to provide a link to Edmonton via a new large diameter pipeline. The mainline system which originates in Edmonton is expected to evolve and grow as oil sands production comes on line. The completion of Terrace Phase III expansion is one of the priorities for Enbridge in 2003. Other projects involve the extension of one of its lines from Mokena to Chicago, the segregation of batches on the system to improve quality of its deliveries, and extension and expansion into new markets. Shipper support will determine the scale of these developments. The Canadian Association of Petroleum Producers (CAPP) has undergone a market study, as has Enbridge (Oil Sands Markets Study) in an effort to better understand markets and potential markets. It will assist in the determination of which pipeline infrastructure requires expansion, as well as the extent of infrastructure required to support new markets. tabs., figs

    Full Text Available Rapid economic and cultural transition in the United Arab Emirates (UAE has been accompanied by new challenges to public health; most notably a rapid rise in chronic disease. Breastfeeding is known to improve health outcomes in adulthood, is associated with reduced risk of developing chronic disease, and is therefore an important public health issue for this rapidly increasing population. Factors associated with infant feeding practices were examined in a cohort of 125 Emirati women and their infants, with data collected at birth and 3, 6 and 15 months postpartum by questionnaires and interviews. Participants were recruited in the Corniche Hospital, the main maternity hospital in the city of Abu Dhabi. Factors affecting the duration of breastfeeding and the introduction of complementary foods were investigated using univariate and multivariate statistics. Recommended infant feeding practices, such as exclusive breastfeeding for the first six months of life and timely introduction of appropriate complementary foods, were poorly adhered to. Factors implicated in early cessation of breastfeeding included: time to first breastfeed, mother’s education level, employment status and early introduction of complementary foods.

    The objective of this review is to discuss definition, determinants, and management issues of the metabolic syndrome in children with a focus on South Asians. The literature search was done using the PubMed search engine (National Library of Medicine, Bethesda, MD, USA). Manual searches for other important references and medical databases were also done. There is a need for an integrated definition of the metabolic syndrome in children and adolescents, taking cognizance of the ethnic-specific variations. Obesity and body fat patterning are important determinants of insulin resistance and the metabolic syndrome in children and ethnic variations in these parameters are seen. Excess body fat and thicker truncal subcutaneous fat are important predisposing factors for development of insulin resistance in South Asian children. Because the metabolic syndrome tracks into adulthood, its manifestations need to be recognized early for prevention of diabetes and coronary heart disease. Therapeutic lifestyle changes, maintenance of high levels of physical activity and normal weight are most important strategies; pharmacologic therapy for individual components of the metabolic syndrome is occasionally needed. The metabolic syndrome in children is an important clinical marker of diabetes and coronary heart disease in adults. In view of the rapid increase in the metabolic syndrome in most populations, high-risk screening and effective public-intervention educational programs are urgently needed.

    Asian trace gas and aerosol emissions into carbon, nitrogen, and other elemental cycles will figure prominently in near term Earth system evolution. Atmospheric hydrocarbon measurements resolve numerous chemical species and can be used to investigate sourcing for key geocarriers. A recent aircraft study of biomass burning and lightning (BIBLE A) explored the East Asian atmosphere and was unique in centering on the Indonesian archipelago. Samples of volatile organics taken over/between the islands of Japan, Saipan, Java, and Borneo are here examined as a guide to whole-air-based studies of future Asian biogeochemistry. The midlatitude onshore/offshore pulse and tropical convection strongly influence concentration distributions. As species of increasing molecular weight are considered, rural, combustion, and industrial source regimes emerge. Methane-rich inputs such as waste treatment and rice cultivation are evidenced in the geostrophic outflow. The Indonesian atmosphere is rich in biomass burning markers and also those of vehicular activity. Complexity of air chemistry in the archipelago is a direct reflection of diverse topography, land use, and local economies in a rapidly developing nation. Conspicuous in its absence is the fingerprint for liquefied petroleum gas leakage, but it can be expected to appear as demand for clean fossil fuels rises along with per capita incomes. Combustion tracers indicate high nitrogen mobilization rates, linking regional terrestrial geocycles with open marine ecosystems. Sea to air fluxes are superimposed on continental and marine backgrounds for the methyl halides. However, ocean hot spots are not coordinated and suggest an intricate subsurface kinetics. Levels of long-lived anthropogenic halocarbons attest to the success of international environmental treaties while reactive chlorine containing species track industrial air masses.

    MetSkill is a professional development program for metallurgical engineers that integrates with normal duties in their first one or two years of service. Graduates work together on a structured technical project, facilitated by specialists and supported by formal learning, and ultimately reported to their technical managers. The program enables graduates to "fill the gaps" in their undergraduate education, which is increasingly pertinent as engineering degrees become more general. Participants report that they enjoy the focus on more challenging (rewarding) aspects of their jobs and feel more confident about problem solving. Sponsor companies add that the relationships developed with external technical specialists enhances opportunities for innovation and development. MetSkill was delivered to two major resource companies in Australia in 2012. This paper provides an outline of the program and the reasons for its success, and demonstrates how the learning model could be applied to groups of graduates in other engineering disciplines.
