    In western New York State interbedded pyritic silty green and dark grey shales and siltstone of the Hanover Member, Java Formation, West Falls Group, are overlain by thick pyritic dark grey-black shale of the Dunkirk Member of the Canadaway formation. The dark shales in the upper Hanover and Dunkirk contain a diverse and well preserved conodont fauna which allows precise placement of the Frasnian-Famennian boundary at several described sections. At Pt. Gratiot, in far western New York State, the contact between the Hanover and Dunkirk is disconformable. The Frasnian-Famennian boundary is marked by a pyritic lag deposit at the base of the Dunkirk which contains Palmatolepis triangularis and Pa. subperlobata. The underlying upper Hanover is characterized by Pa. bogartensis , Pa. cf. Pa. rhenana, Pa. winchelli, and Ancyrognathus (asymmetricus/calvini) Eastward, in the direction of the paleo-source area, the Frasnian-Famennian boundary is within the upper Hanover Member. At Irish Gulf the boundary is recognized within a 10 cm thick laminated pyritic dark grey shale bed 3.0 m below the base of the Dunkirk. Palmatolepis triangularis and Pa. subperlobata occur below a conodont-rich lag layer in the upper 2 cm of the bed. Palmatolepis bogartensis , Pa. cf. Pa. rhenana, Ancyrodella curvata, and Icriodus alternatus occur in the underlying 8 cm. Palmatolepis triangularis and Pa. winchelli occur in an underlying dark shale bed separated from the boundary bed by a hummocky cross-bedded siltstone layer.

    2011-06-07

    The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated a grain storage facility at the northeastern edge of the city of Hanover, Kansas, from 1950 until the early 1970s. During this time, commercial grain fumigants containing carbon tetrachloride were in common use by the grain storage industry to preserve grain in their facilities. In February 1998, trace to low levels of carbon tetrachloride were detected in two private lawn and garden wells near the former grain storage facility at Hanover, as part of a statewide USDA private well sampling program that was implemented by the Kansas Department of Health and Environment (KDHE) near former CCC/USDA facilities. In July 2007, the CCC/USDA sampled indoor air at nine residences on or adjacent to its former facility to address the residents concerns. Low levels of carbon tetrachloride were detected at four of the nine homes. Consequently, the CCC/USDA has conducted investigations, under the direction of the KDHE, to determine the source and extent of the carbon tetrachloride contamination that might be associated with the former facility. In July 2007, the CCC/USDA sampled indoor air at nine residences on or adjacent to its former facility to address the residents concerns regarding vapor intrusion (VI). Low levels of carbon tetrachloride were detected at four of the nine homes. Because carbon tetrachloride found in private wells and indoor air at Hanover might be linked to historical use of fumigants containing carbon tetrachloride at its former grain storage facility, the CCC/USDA has conducted investigations to determine the source and extent of the carbon tetrachloride contamination that may be associated with the former facility. The results of the comprehensive investigation at Hanover indicate that no unacceptable risk to human health currently exists from exposure to surface and subsurface soils by either ingestion, inhalation or dermal contact. No risk is

  7. Highlighting High Performance: Clearview Elementary School, Hanover, Pennsylvania

    Energy Technology Data Exchange (ETDEWEB)

    2002-08-01

    Case study on high performance building features of Clearview Elementary School in Hanover, Pennsylvania. Clearview Elementary School in Hanover, Pennsylvania, is filled with natural light, not only in classrooms but also in unexpected, and traditionally dark, places like stairwells and hallways. The result is enhanced learning. Recent scientific studies conducted by the California Board for Energy Efficiency, involving 21,000 students, show test scores were 15% to 26% higher in classrooms with daylighting. Clearview's ventilation system also helps students and teachers stay healthy, alert, and focused on learning. The school's superior learning environment comes with annual average energy savings of about 40% over a conventional school. For example, with so much daylight, the school requires about a third less energy for electric lighting than a typical school. The school's innovative geothermal heating and cooling system uses the constant temperature of the Earth to cool and heat the building. The building and landscape designs work together to enhance solar heating in the winter, summer cooling, and daylighting all year long. Students and teachers have the opportunity to learn about high-performance design by studying their own school. At Clearview, the Hanover Public School District has shown that designing a school to save energy is affordable. Even with its many innovative features, the school's $6.35 million price tag is just $150,000 higher than average for elementary schools in Pennsylvania. Projected annual energy cost savings of approximately $18,000 mean a payback in 9 years. Reasonable construction costs demonstrate that other school districts can build schools that conserve energy, protect natural resources, and provide the educational and health benefits that come with high-performance buildings.

    ENGLISH ABSTRACT: A township planner wants to house many people within a given area, without exceeding a tight budget, while yet respecting certain standards. These specify a variet::y of house t::ypes. They also imply indirect:: effect::s such as open space, schools or hospitals: more people use more of these. But as we build more schools, less space remains for houses, so we are left with fewer people l requiring fewer schools.
    We show how to capture such simultaneous interactions. We also discuss some unexpected results. These arise notably in the tr~nsition from fractional to integer solutions.

    Low concentrations of carbon tetrachloride in groundwater and vapor intrusion into a limited number of residences (attributable to the contaminant concentrations in groundwater) have been identified in Hanover, Kansas, at and near a grain storage facility formerly leased and operated by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA). At the request of the Kansas Department of Health and Environment (KDHE 2009h), the CCC/USDA has prepared this Corrective Action Study (CAS) for the facility. The CAS examines corrective actions to address the contamination in groundwater and soil vapor.

  14. The impact of shopping mall development on small township retailers

    Directory of Open Access Journals (Sweden)

    Andre Ligthelm

    2012-05-01

    Full Text Available The retail sector forms a critical element of a community’s economic and social welfare. It provides people with choices and services. These choices were until recently very limited in township areas. The pre-1994 retail landscape was dominated by small, often informal businesses offering basic household necessities to relatively low income earners. This has resulted in township residents’ preference to shop outside townships, known as ‘outshopping’. Rapid income growth of township residents since 1994 resulted in a substantial increase in consumer expenditure in these areas, known as ‘in-bound shopping’. This lucrative emerging market forms the last retail frontier in South Africa and is being explored by national retailers, especially supermarket chains. This article is aimed at establishing the impact of shopping mall development in townships on the traditional small township retailers including spaza/tuck shops. The net balance sheet on the impact of shopping mall development on small township retailers clearly suggests a decline in the township retailers’ market share. A change in small business model towards, inter alia, effective customer service with a small dedicated assortment of merchandise, satisfaction of emergency needs, selling in small units and extension of credit facilities may result in the survival of some small township retailers (albeit often at a smaller turnover.

    Pet overpopulation is a problem for humans not only because of the increased rabies exposure risk but also because it puts a strain on animal control agencies, which must care for, house, and often euthanize the unwanted animals. New Hanover County, North Carolina, Animal Control Services saw the need to control this problem and developed a plan to diminish the number of unwanted companion animals in its community. With the help of training through the UNC Management Academy for Public Health, they created a successful business plan to build an on-site spay/neuter facility. The facility began operations in 2004. As of January 31, 2006, a total of 1,108 surgeries had been completed in the new facility, with no added cost to taxpayers. The facility has been a success for Animal Control Services, the Health Department, and the community as a whole.

    Full Text Available The objective of this study was to determine the prevalence of depressive symptoms in Jamaican adolescents and examine its association with individual and family factors. We used an abbreviated form of the Beck's Depression Inventory II (BDI-II to assess depressive symptoms among 748 students, attending public high schools in the parish of Hanover Jamaica. In the analysis, we classified adolescents with scores in the upper quartile of the depressive symptom score as having depressive symptoms. Multivariate logistic regression was used to determine the predictors of depressive symptoms. 14.2% of participants reported depressive symptoms. There was association between engagement in sexual activity [Odds Ratio (OR = 1.61, 95% Confidence Interval (CI = 1.02-2.51], parental monitoring of adolescent activity (OR=2.04, 95%CI=1.33 -3.12, maternal affection and support (OR= 4.07, 95%CI= 2.62-6.33, and paternal affection and support (OR= 1.58, 95%CI= 1.05-2.39 with self reported depressive symptoms at the bivariate level. In the final model, depressive symptoms was associated with perceived lack of maternal affection and support (OR= 4.06, 95%CI= 2.61-6.32 and showed marginal association with being sexually experienced (OR= 1.59, 95%CI= 1.00-2.52. As most homes are female-headed, establishing support systems for the mother to take care of their adolescent children may decrease the odds of depressive symptoms. Sexually experienced adolescents may require screening for depression. Further research is required to fully explore all factors that could predispose Jamaican adolescents to depression.

  1. Final work plan : supplemental upward vapor intrusion investigation at the former CCC/USDA grain storage facility in Hanover, Kansas.

    The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated a grain storage facility at the northeastern edge of the city of Hanover, Kansas, from 1950 until the early 1970s. During this time, commercial grain fumigants containing carbon tetrachloride were in common use by the grain storage industry to preserve grain in their facilities. In February 1998, trace to low levels of carbon tetrachloride (below the maximum contaminant level [MCL] of 5.0 {micro}g/L) were detected in two private wells near the former grain storage facility at Hanover, as part of a statewide USDA private well sampling program that was implemented by the Kansas Department of Health and Environment (KDHE) near former CCC/USDA facilities. In 2007, the CCC/USDA conducted near-surface soil sampling at 61 locations and also sampled indoor air at nine residences on or adjacent to its former Hanover facility to address the residents concerns regarding vapor intrusion. Low levels of carbon tetrachloride were detected at four of the nine homes. The results were submitted to the KDHE in October 2007 (Argonne 2007). On the basis of the results, the KDHE requested sub-slab sampling and/or indoor air sampling (KDHE 2007). This Work Plan describes, in detail, the proposed additional scope of work requested by the KDHE and has been developed as a supplement to the comprehensive site investigation work plan that is pending (Argonne 2008). Indoor air samples collected previously from four homes at Hanover were shown to contain the carbon tetrachloride at low concentrations (Table 2.1). It cannot be concluded from these previous data that the source of the detected carbon tetrachloride is vapor intrusion attributable to former grain storage operations of the CCC/USDA at Hanover. The technical objective of the vapor intrusion investigation described here is to assess the risk to human health due to the potential for upward migration of carbon tetrachloride and

    Asia is becoming one of the most important regions in the world from the political, economic and scientific point of view. Germany believes that it is becoming increasingly necessary to cooperate with certain Asian countries especially for scientific and technological reasons. Above and beyond exchanges of scientists, the scientific and technological cooperation will be organized to cover projects with specific targets and to find solutions to important problems. International economic development is characterized by a mixture of competition and cooperation within the context of growing globalization. Germany, being one of the world's largest exporting nation, must therefore combine its active role in cooperation with these countries in the fields of education, research and innovation with economic cooperation. The Laser Centre Hanover pursues the goal of establishing and operating a Chinese German center for training and further education in laser technology and setting up a joint platform for long-term German Chinese cooperation in laser technology. An optimized training infrastructure combined with modern production processes support consequently long-term German businesses in China and secures their market-shares. LZH establishes Laser academies for skilled workers and technical decision makers in Shanghai and Changchun together with local universities and German partners. Due to the economic growth, Russia records since more than two years, the economic conditions are improving the cooperation between Germany and Russia step-by-step. The main goal of Russian science-politics is to stabilize an efficient scientific-technical potential with better chances in the global competition. The German-Russian scientific and technological cooperation plays an important role in this context. It has considerably increased in the last years in terms of width and depth and virtually includes all areas of science and technology at present. The region around Moscow is regarded

It starts bydefining and clarifying the concepts of ‘entrepreneur’ and ‘social entrepreneurship’. Itcontinues by looking in more depth into township life and its challenges. This is done throughreviewing the literature and observations obtained through participant observation research.Post-foundationalist practical theology believes in interdisciplinary dialogue as a means ofallowing the concept of social entrepreneurship to bring about a sustainable townshipeconomy. From the author’s observations, it became apparent that to see the attainment of asustainable township economy, training and development should start with a strong emphasison personal identity and interpersonal and business skills. The author, therefore, proposes aholistic approach to social entrepreneurship.

    McSwain, Kristen Bukowski; Gurley, Laura N.; Antolino, Dominick J.

    2014-01-01

    A major issue facing the greater New Hanover County, North Carolina, area is the increased demand for drinking water resources as a result of rapid growth. The principal sources of freshwater supply in the greater New Hanover County area are withdrawals of surface water from the Cape Fear River and groundwater from the underlying Castle Hayne and Peedee aquifers. Industrial, mining, irrigation, and aquaculture groundwater withdrawals increasingly compete with public-supply utilities for freshwater resources. Future population growth and economic expansion will require increased dependence on high-quality sources of fresh groundwater. An evaluation of the hydrogeology and water-quality conditions in the surficial, Castle Hayne, and Peedee aquifers was conducted in New Hanover, eastern Brunswick, and southern Pender Counties, North Carolina. A hydrogeologic framework was delineated by using a description of the geologic and hydrogeologic units that compose aquifers and their confining units. Current and historic water-level, water-quality, and water-isotope data were used to approximate the present boundary between freshwater and brackish water in the study area. Water-level data collected during August–September 2012 and March 2013 in the Castle Hayne aquifer show that recharge areas with the highest groundwater altitudes are located in central New Hanover County, and the lowest are located in a discharge area along the Atlantic Ocean. Between 1964 and 2012, groundwater levels in the Castle Hayne aquifer in central New Hanover County have rebounded by about 10 feet, but in the Pages Creek area groundwater levels declined in excess of 20 feet. In the Peedee aquifer, the August–September 2012 groundwater levels were affected by industrial withdrawals in north-central New Hanover County. Groundwater levels in the Peedee aquifer declined more than 20 feet between 1964 and 2012 in northeastern New Hanover County because of increased withdrawals. Vertical gradients

    The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated a grain storage facility at the northeastern edge of the city of Hanover, Kansas, from 1950 until the early 1970s. During this time, commercial grain fumigants containing carbon tetrachloride were in common use by the grain storage industry to preserve grain in their facilities. In February 1998, trace to low levels of carbon tetrachloride (below the maximum contaminant level [MCL] of 5.0 {micro}g/L) were detected in two private wells near the former grain storage facility at Hanover, as part of a statewide USDA private well sampling program that was implemented by the Kansas Department of Health and Environment (KDHE) near former CCC/USDA facilities. In April 2007, the CCC/USDA collected near-surface soil samples at 1.8-2 ft BGL (below ground level) at 61 locations across the former CCC/USDA facility. All soil samples were analyzed by the rigorous gas chromatograph-mass spectrometer analytical method (purge-and-trap method). No contamination was found in soil samples above the reporting limit of 10 {micro}g/kg. In July 2007, the CCC/USDA sampled indoor air at nine residences on or adjacent to its former facility to address the residents concerns regarding vapor intrusion. Low levels of carbon tetrachloride were detected at four of the nine homes. Because carbon tetrachloride found in private wells and indoor air at the site might be linked to historical use of fumigants containing carbon tetrachloride at its former grain storage facility, the CCC/USDA is proposing to conduct an investigation to determine the source and extent of the carbon tetrachloride contamination associated with the former facility. This investigation will be conducted in accordance with the intergovernmental agreement between the KDHE and the Farm Service Agency (FSA) of the USDA. The investigation at Hanover will be performed, on behalf of the CCC/USDA, by the Environmental Science

    Ardón, F; Döhring, A; Le Thi, X; Weitze, K F; Waberski, D

    2003-04-01

    The goal of this study was to determine the ability of the Hanover gilt model to assess in vivo fertilizing capacity of preserved sperm and to consider whether any modifications to this model were needed. This model evaluates the fertilizing capacity of semen based on the fertilization rate, the rate of normal embryos and the accessory sperm count of 3-5-day embryos. Its distinguishing characteristics are the use of one-time insemination of sperm in reduced numbers, of spontaneously ovulating gilts and of ovulation detection through ultrasound examination of ovaries. Reduced sperm numbers allow for an accurate evaluation of the fertilizing potential of different semen treatments, thereby avoiding the compensatory effect of doses calibrated to maximize fertility. The model's usefulness was assessed in a trial run designed to compare the fertilizing capacity of liquid boar semen diluted into two different extenders. The diluent, the boar and the backflow, had no significant effect on any of the parameters studied. Gilts inseminated less than 24 h before ovulation had a significantly higher (p semen), while using relatively few gilts and little time.

  2. Long-term simulation of the activated sludge process at the Hanover-Gümmerwald pilot WWTP.

    2005-04-01

    The aim of this study was to obtain a validated model, consisting of the Activated Sludge Model No. 3 (ASM3) and the EAWAG bio-P module, which could be used as a decision tool for estimating the maximum allowable peak flow to wastewater treatment plants during stormwater conditions. The databases used for simulations originated from the Hanover-Gummerwald pilot plant subjected to a series of controlled, short-term hydraulic shock loading experiments. The continuous influent wastewater composition was generated using on-line measurements of only three parameters (COD, N-NH4+, P-PO4 3-). Model predictions were compared with on-line data from different locations in the activated sludge system including the aerobic zone (concentrations of N-NH4+, N-NO3-) and secondary effluent (concentrations of P-PO4 3-). The simulations confirmed experimental results concerning the capabilities of the system for handling increased flows during stormwater events. No (or minor) peaks of N-NH4+ were predicted for the line with the double dry weather flowrate, whereas peaks of N-NH4+ at the line with the quadruple dry weather flowrate were normally exceeding 8 g Nm(-3) (similar to the observations).

    Concerns about overuse and potential contamination of major aquifers in the southeastern part of North Carolina resulted in the initiation of a subsurface water quality study in February 2001. The focus of this study was to examine variations in nutrients (NO3-, TRP, SO42- Cl-, NH4+) and total dissolved Fe in the Cretaceous Peedee and Tertiary Castle Hayne Limestone aquifers of northeastern New Hanover County. Water samples were collected monthly for one year from sixteen wells located in the Porters Neck area (west of the Intracoastal Waterway and south of Futch Creek) and four springs located on the south side of Futch Creek. Variations in selective nutrient concentrations were measured between and within each aquifer. Concentrations of NH4+ and Fe increased in the Peedee sandstone aquifer during the warmer summer and early fall months. In late summer to early fall, Fe, NO 3-, NH4+, and TRP concentrations in the Castle Hayne Limestone aquifer were significantly higher than in the spring and winter months. Chloride and SO 42- concentrations for the Castle Hayne Limestone aquifer both increased during the warmer months, probably as a result of saltwater intrusion. Factors considered for nutrient and Fe variance include: temperature variation, anaerobic conditions, subsurface stratigraphy/structure, recharge locations, site location and surface fertilization. The shallower Castle Hayne Limestone aquifer showed seasonal variability in the study area, whereas the Peedee sandstone aquifer showed little to no seasonal variability. Increases in NO3- and TRP lagged slightly behind periods of high fertilization and were more prevalent down-dip of a major golf course. Nutrient content and seasonal variation of Futch Creek springs indicated that they originate from the Castle Hayne Limestone aquifer.

  6. PA strategies in Korea

    International Nuclear Information System (INIS)

    Chung, J.K.

    1998-01-01

    The main purpose of promoting nuclear public acceptance in Korea is to secure necessary sites for construction of large nuclear facilities in a timely manner. Another important purpose is to maintain a good neighbor relationship between the operator of nuclear facilities and local population. To promote better understanding about the nation's peaceful nuclear programs to the general public is another facet of nuclear information activities. However, opposition by the local population living around the nuclear facilities has always been aggressive. The primary concern of the local population is basically focused on the financial issues. Professional nationwide anti-nuclear groups are abetting the local population directly but with fabricated information in order to increase psychological fears. In an effort to compensate for the psychological and sociological burdens of the local population, the Korean government arranged legal provisions. To this end, beginning in 1990, community support programs have been implemented. As the nation's nuclear power program expanded, anti-nuclear activities also became very active. Public information programs should be expanded. Some highlights of public acceptance programs of the nuclear industries are 'Go and Meet' rather than 'Come and See', 'Act rather than react', 'Proper messages to proper target groups', 'Maximum use of the third party communicators', and so on. An orchestrated effort among the nation's nuclear industries is essential to the successful implementation of the PA strategies. (author)

  7. Violent political contexts and the emotional concerns of township youth.

    1996-02-01

    This article presents the findings of a series of studies that examine the perceptions of black South African youth about township life and the civil conflict and violence it encompasses. The studies were conducted with comparable samples of 58-82 youth at 3 points in South Africa's history, all characterized by high levels of violence but differing in terms of their political contexts. These contexts were overt State-community conflict, covert opposition and political repression, and intracommunity violence. The data revealed that in all 3 contexts youth reported a high exposure to violence, but only when violence occurred in the context of intracommunity conflict was it subjectively construed to be the most problematic. Reasons for this may include the real increase in more extreme forms of violence, including deaths, that occurs in intracommunity violence and the blurring of the distinction between political and criminal violence in this context.

    To find out the economic laws regulating medical service demand in accordance with influencing factors at the township level, thus to provide references for further adjusting the medical service demand reasonably in the future. The model of medical service demand was established to measure the elasticity of demand in 49 township health clinics in 1995, 1999, 2003 and 2007. The price elasticity of outpatient and inpatient demand was stable during the four periods, and the average value was -0.029 and -0.132 respectively; the average value of income elasticity was 0.973 and 0.977, registering a downward trend in general. The medical service demand at the township level is price inelastic, indicating that it is a necessity for rural residents. The downward trend of income elasticity under the influence of some health policies illustrates a lightening in economic burden for medical service demand among rural residents in township health clinics.

  11. URBAN RECONFIGURATIONS OF SPACE AND PLACE WITHIN TOWNSHIP TOURISM

    Directory of Open Access Journals (Sweden)

    Ana Craciunescu

    2015-07-01

    Full Text Available Nowadays global economic and cultural constellation determined urban communities to find a solution in order to preserve local identity and at the same time to attract capital into the area. Tourism represents in our opinion one of the greatest solutions ever exploited in mankind’s history which erases boundaries of nations and economic policies, creating glocalized encounters. In the case of a city, tourism or township tourism becomes an economical, political and cultural vector that unifies urban space which develops a network of genuine and artificial urban inter-relations between the principal stakeholders. The city as a destination must be a ‘safe’ construct that meets the expectations of various kinds of travellers and of their different travelling motivations. We believe that to a certain extent, the (rebranding of cities consists in the creation of a harmonized space that would reiterate the home-facilities of the traveller. A matter of life-style and life-quality, this issue will be analysed through the lens of travelling as a leisure activity, or as a way of escaping monotone routine of daily living, eventually a way of reinvesting income and creating economic equilibrium.

    Full Text Available The campaign to end povertyby 2030,as advocated by the World Bank,has multifacetedcomponents. Food security and abject poverty have received more attention;however,little attention has been focused on housing insecurity. This is important,especially giventhe fact that it iswidely acknowledged that housing satiates an essential human need forphysical security, dignity and prosperity,among other things. Housing, for some time,has been observed as crucial to individual and family functioning. As indicated byorganisations such as the United Nations Habitat, the importance of appropriate housingis explained by the fact that safe housing is seen as a basic need among other needs suchas food, all of which are regarded as central components of the security of ordinaryhouseholds, particularly in developing countries. In 2015, more than 1.5 billionpeopleinthe world were living in housing that was unsafe and inadequate, while in the meantime,millions experienced eviction from their homes every year, with at least 100 millionpeople becoming homeless on any given day.Therefore, it ispertinent to understand whatdetermines housing insecurity. The studyaims toinvestigatefactors thatdetermineshousing insecurity. Using data collected from Sharpeville and Bophelong, two lowincome townships in South Africa that are particularlyvulnerable to housing insecurity,the study employs amultinomiallogisticregression to investigate the effects of head ofhousehold and the general household characteristics on housing insecurity. Theresults ofthe regression analysis show that income, gender, number of people in the household andthe amount paid to bond or rent are significant predictors of housing insecurity.Contentious issues like access to land and job opportunities are areas of further study inunderstanding the multifaceted phenomenon of housing insecurity.

    A cross-sectional study explored the presence and power of developmental assets in a sample of youth from rural South African townships. Learners (female = 58%; M age  = 17.1; N = 505) attending three township high schools completed self-report measures of developmental assets and thriving outcomes. Participants reported contextual assets (e.g., family, school, community) in the vulnerable ranges, with gender, family structure, and school type accounting for some differences. Correlation and regression analyses revealed that five asset contexts (family, school, community, personal, social) were uniquely predictive of thriving outcomes. Discussion focuses on contextual expressions of positive youth development among Zulu township youth in challenging environments. © 2017 The Authors.

The alpha decay spectrum was measured with a semiconductor spectrometer of 18 keV effective resolution (FWHM). Over 13 new lines were identified. The gamma ray spectra of Np-237 and Th-233 were obtained with a Ge-Li detector low and medium range energy lines, and with Si-Li detector for the low energy region. A continuous purification method of Np-237 from its comparatively short-lived daughter Pa-233 was applied. A high number of new lines were identified in both spectra. The gamma-gamma coincidence spectra were obtained with INa(T{sub 1}) detectors. (Author) 54 refs.

    Background . Township hospitals in China provide rural communities with basic but much needed critical health care services. The doctors working in these hospitals often feel unsatisfied when considering their work schedules and financial rewards. Method . To explore job satisfaction of health workers in a township hospital, a qualitative study was conducted of 39 doctors from five township hospitals in Guangxi Zhuang Autonomous Region. The goal was to understand the level of job satisfaction of doctors and to make recommendations for improvements. Results . About 75% (28/39) of the doctors expressed negative attitudes related to their work conditions. Slightly more than half (22/39) mentioned they should receive greater compensation for their work and more than one were seriously considering other options. Many participants (35/39) showed their satisfaction about the achievement of serving as a doctor. Conclusion . Their main concerns related to job satisfaction included working conditions, financial rewards, and the doctor's relationships with patients. Increasing the incomes and fringe benefits of healthcare workers, improving their work conditions, and providing training and continuing education opportunities would help rural clinics retain doctors and eliminate the current unsatisfactory conditions. The findings also highlight the need for the government to increase financial support of township hospitals.

  4. Living with Bats: The Case of Ve Golokuati Township in the Volta Region of Ghana

    Directory of Open Access Journals (Sweden)

    Jesse S. Ayivor

    2017-01-01

    Full Text Available Transmission of zoonotic pathogens from bats to humans through direct and indirect contact with bats raises public apprehension about living close to bats. In the township of Ve Golokuati in Ghana, several “camps” of Epomophorus gambianus roost in fruit trees that provide ecosystems services for residents. This study explored human-bat interaction in the township and the potential risks of disease transmission from bats to humans. Data were derived through questionnaire administration and participatory appraisal approach involving focus group discussions, participatory landscape mapping, and transect walk. The study found that most human activities within the township, such as petty-trading, domestic chores, and children’s outdoor recreation, exposed people to bats. Though there have been no reported cases of disease spillover from bats to humans from the perspective of residents and from medical records, respondents whose activities brought them closer to bats within the township were found to be more likely to experience fevers than those who do not interact with bats frequently. The study recommends education of community members about the potential risks involved in human-bat interactions and makes suggestions for reducing the frequent interactions with and exposure to bats by humans.

    Full Text Available Ecotourism, as a multibillion dollars business, is an industry with high potentials for economic competition. One of the proper solutions for developing ecotourism is better identification of different regions where there is a tourism capacity and accurate planning for performing feasibility study of those regions in terms of attracting ecotourism as well as creating infrastructures in those regions. This paper evaluates capacities and power of tourism as well as nature tourism in Isfahan Township using Geographic Information System and Analytical Hierarchy Process. The present research is applied and research method is descriptive-analytical. Meanwhile, to analyze data, Arc GIS is used. Findings indicate that regarding the map of ecotourism capacity of Isfahan townships, resulted from combining various climatologically, geological, hydrological, topological maps and access maps, the township is not homogeneous in terms of nature tourism and coastal parts of the township (regions around Zayand-e-Rood have better condition than other parts and should be considered for tourism development planning.

    Full Text Available A number of adolescents have been observed drinking alcohol, pushing and abusing drugs and also stealing cars. A lot of adolescents idle in the township streets, girls are falling pregnant and dropping out of school. No research has been done to elicit the opinions of families on the everyday life of the adolescents in this township. The objectives of this research were twofold, namely: To explore and describe the families’ opinions on the everyday life of adolescents in a specific township in Swaziland, and to describe guidelines for advanced psychiatric nurse practitioners to assist these families to mobilize resources in order to promote, maintain and restore mental health as integral part of health of adolescents in this township. A qualitative, exploratory, descriptive and contextual design was used where the research was conducted in two phases. Trustworthiness measures as well as ethical measures were applied throughout the research. Five categories were identified from the result of the focus group interviews with families: Adolescents presenting ineffective communication patterns due to lack of support from their families; adolescents engaging into risky lifestyles related to lack of support and healthy relationships with their parents; families unable to create a supportive and conducive environment for their adolescents due to their focus on own family stumbling blocks and non-availability of recreational centres related to lack of a supportive and conducive environment in the community and inadequate accommodation leading to overcrowding. Guidelines for advanced psychiatric nurse practitioners were deducted from identified themes and the literature control.

    Full Text Available Abstract Background Sichuan Province is an agricultural and economically developing province in western China. To understand practices of prescribing medications for outpatients in rural township health centers is important for the development of the rural medical and health services in this province and western China. Methods This is an observational study based on data from the 4th National Health Services Survey of China. A total of 3,059 prescriptions from 30 township health centers in Sichuan Province were collected and analyzed. Seven indicators were employed in the analyses to characterize the prescription practices. They are disease distribution, average cost per encounter, number of medications per encounter, percentage of encounters with antibiotics, percentage of encounters with glucocorticoids, percentage of encounters with combined glucocorticoids and antibiotics, and percentage of encounters with injections. Results The average medication cost per encounter was 16.30 Yuan ($2.59. About 60% of the prescriptions contained Chinese patent medicine (CPM, and almost all prescriptions (98.07% contained western medicine. 85.18% of the prescriptions contained antibiotics, of which, 24.98% contained two or more types of antibiotics; the percentage of prescriptions with glucocorticoids was 19.99%; the percentage of prescriptions with both glucocorticoids and antibiotics was 16.67%; 51.40% of the prescriptions included injections, of which, 39.90% included two or more injections. Conclusions The findings from this study demonstrated irrational medication uses of antibiotics, glucocorticoids and injections prescribed for outpatients in the rural township health centers in Sichuan Province. The reasons for irrational medication uses are not only solely due to the pursuit of maximizing benefits in the township health centers, but also more likely attributable to the lack of medical knowledge of rational medication uses among rural doctors and the

    To understand the quality of malaria blood examinations in township-level hospitals, so as to provide the evidence for continuing the malaria blood examinations in the stage of post-malaria elimination. A total of 64 township hospitals were investigated and 640 negative malaria blood slides were scored individually according to 10 indicators in "Malaria Elimination Technical Scheme" in 2013 and 2014. The single and multiple indicators were calculated, and the work of blood examinations and situation of technicians were investigated. The data of malaria blood examinations and patient discovery in township hospitals of Nantong City were collected and analyzed during the period of 2011-2014. For the single indicator, 29.5% of the thick blood films did not reach the standard, and 35.8% of thin blood films did not reach the standard. For the multiple indicators, blood slides with more than 4 indicators below the standard (poor quality) accounted for 32.5%. From malaria blood examinations and malaria situation, the number of slides was 194 635 during the period of 2011-2014, and there were no local vivax malaria casesin 4 consecutive years from 2011 to 2014, and local malaria has been effectively controlled in Nantong City. For health facilities where malaria patients initially presented, the township and village level accounted for 16.3%, and county and higher level accounted for 83.7%. The quality of malaria blood examinations in township level hospitals of Nantong City is not high and the microscopic examination has a relatively low efficiency in the discovery of malaria cases. A new model for malaria blood examinations needs to be further explored.

  18. Micro-enterprise predicament in township economic development: Evidence from Ivory Park and Tembisa

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Aim: In response to the developmental need to stimulate micro-enterprise growth in South African townships, the paper poses the question: what approaches are most likely to have a positive impact on township businesses, given current micro-enterprise dynamics? Setting: Primary research was undertaken in two neighbouring townships in Gauteng province, in Ivory Park and Tembisa. Methods: The data comprises a geospatial census of enterprise activities, a survey of select firms and qualitative interviews with business owners. The research utilised a small-area census approach to obtain data on business activities within an area of approximately 2km2 in each site. The census enumerated 2509 micro-enterprises in Ivory Park and 1722 micro-enterprises in Tembisa. Firm interviews were conducted with business owners in four sectors: grocery retail, liquor retail, hair care and early childhood development centres. Results: The business census identifies a strong similarity in the structure of the townships’ informal micro-entrepreneurship despite the considerable differences in the socio-economic status of the respective case sites. The enterprise survey highlights the resource constraints of township businesses and thinness of local markets. Interviews with entrepreneurs reveal four main pathways through which individuals enter into self-employment with the most dynamic enterprises established by inward investing entrepreneurs. Spatial considerations exert an influence on the position of enterprise sectors, whilst access to land and business infrastructure are notable constraints. Conclusion: Reflecting on the evidence, the paper concludes with making a call for a more low-geared development approach, focusing on lessening the legal, institutional and regulatory obstacles to enterprise growth as a first step. Municipalities have an important role in liberalising the spaces and places where township informal enterprises can and should be permitted to trade as well as

    2014-11-01

    Full Text Available This article offers an appraisal of the social ministry of Pentecostal churches through fellowship, healing and livelihood creation in the township communities of the city of Tshwane. In meeting this aim the discussion advances a thesis of these churches as agents of social support and survival of the downcast. In particular, the article attempts to show how these churches exert themselves towards establishing not only moral responsibility, but also a context where the weakest and the least privileged can learn how to survive. The squatter camp people are unique with the special challenges requiring distinctive consideration. Pentecostal churches believe that the lost people matter to God and are of importance to their congregations as well. The backyard Bible study ministries and mutual cooperation strategies are employed for mutual support. Making use of the existing empirical research data and available literature will show how Pentecostal churches in the townships support the laity and community in times of need.

    As one of the densest population occurred in Johor Bahru, development of a new township become necessary in order to cater this growth. Rapid urbanization is a factor of degradation of environmental quality which may increase surrounded temperature through urban heat island (UHI) phenomena. Therefore, this paper is investigating thermal comfort for a new township, Bandar Dato Onn in Johor Bahru, in order to understand the thermal characteristics of a new township and for further mitigation of UHI phenomena. Surface temperature, ambient temperature and relative humidity have been collected from a terrace house of Bandar Dato Onn. Thermal characteristics with the features of time lag and decrement factors were discussed based on the collected data. The time lag of 5 to 8 hours and the decrement factors of 0.02 to 0.06 were recorded during a five-day measurement. It was concluded that human thermal comfort may not be achieved as the heating, ventilation and air conditioning (HVAC) system needed for bedroom and living room. Passive energy design is suggested to be included in the house in order to have human thermal comfort while reducing the electricity consumption towards sustainable future.

  6. The prospects of making small retail outlets in the Townships aggressively competitive

    Directory of Open Access Journals (Sweden)

    Malefane Johannes Lebusa

    2013-12-01

    Full Text Available Historically, township Small Retail Outlets were mostly established for survival and operated under a generally closed market system where the competition was not very strong. However, with the advent of democracy many people lost their formal income through retrenchments and out of desperation, many of these people opened Small Retail Outlets thus most of the existing and new entrants into the township market were unskilled or semiskilled labourers with little or no formal skills in business or entrepreneurship. Such efforts were rarely guided by any specific and informed strategy of identifying and exploiting a gap in the market. With the consolidation of the free market system under democracy, big brand businesses such as Shoprite Checkers and Small Retail Outlets of foreign nationals with different strategies entered and competed in this township market. With fewer formal skills in business and entrepreneurship, the owners of the Small Retail Outlets struggled to compete and thrive under these relatively new economic conditions. Given this situation, I conducted semi-structured interviews with fifteen of these traditional Small Retail Outlets to find out and better understand the challenges they face and the skills that might be needed to aggressively compete in this space. Based on these findings and understandings, I further examined these issues and suggest infusions of specific entrepreneurship skills that could develop their aggressive competitiveness.

    Full Text Available The purpose of this study is to identify risk factors of physical violence in Chinese township hospitals.A cross-sectional survey was used in a sample of 442 general practitioners and 398 general nurses from 90 township hospitals located in Heilongjiang province, China (response rate = 84.8%.A total of 106 of the 840 (12.6% respondents reported being physically attacked in their workplace in the previous 12 months. Most perpetrators were the patients' relatives (62.3%, followed by the patient (22.6%; 73.6% of perpetrators were aged between 20 and 40 years. Of the physical violence incidents, about 56.6% (n = 60 resulted in a physical injury, and 45.4% of respondents took two or three days of sick leave. Reporting workplace violence in hospitals to superiors or authorities was low (9.4%. Most respondents (62.8% did not receive training on how to avoid workplace violence. Logistic regression analyses indicated that general nurses, aged 35 years or younger, and with a higher-level professional title were more likely to experience physical violence. Healthcare workers with direct physical contact (washing, turning, lifting with patients had a higher risk of physical violence compared to other health care workers. Procedures for reporting workplace violence were a protective factor for physical violence; when in place, reporting after psychological violence (verbal abuse, bullying/mobbing, harassment, and threats was more protective than waiting until an instance of physical violence (beating, kicking, slapping, stabbing, etc..Physical violence in Chinese township hospitals is an occupational hazard of rural public health concern. Policies, procedures, and intervention strategies should be undertaken to manage this issue.

  9. Stakeholders' participation in township tourism planning and development: the case of business managers in Soshanguve

    Directory of Open Access Journals (Sweden)

    Acha-Anyi Paul Nkemngu

    2014-01-01

    Full Text Available Stakeholder theory advocates the inclusion and participation of relevant stakeholders in both community and business development. This necessitates a diligent planning process with the aim of working towards pre-determined objectives. Furthermore, the constructive participation of stakeholders in the development process can be said to depend on their understanding of the role they are expected to play. Therefore, the participation of business managers in tourism planning and development can be assessed based on their familiarity with both the general and personal business success factors in their operating environment. This paper assesses the contribution of tourism business operators in Soshanguve Township to tourism development in their community. The study undertakes a quantitative survey of 29 managers of tourism businesses on their perceptions on general business success factors and personal business success factors in Soshanguve Township. The results reveal discrepancies between what the managers perceive to be general business success factors in the community and the factors they consider to have contributed to their personal business success. The inference from the above is that business managers are not optimising on the business potential in their community based on the margin of difference between what they percieve to be the best industry success factors and the implementation of the same in their personal businesses. The study concludes with recommendations on how to breach the gap in order to maximise the contribution of businesses to tourism development in Soshanguve Township. Prime among these is the increase intervention by the local government in the coordination and training of businesses in the community.

  10. Ground-water levels in aquifers used for residential supply, Campton Township, Kane County, Illinois

    Kay, Robert T.; Kraske, Kurt A.

    1996-01-01

    The U.S. Geological Survey, in cooperation with the Campton Township Board of Trustees, measured water levels in the aquifers used for residential supply in Campton Township, Kane County, Illinois. Aquifers used for residential supply are the shallow and deep aquifers in the glacial drift, composed of unconsolidated sand and gravels; the Alexandrian-Maquoketa aquifer, composed of dolomite and shale of the Alexandrian Series and the Maquoketa Group; the Galena-Platteville aquifer, composed of dolomite of the Platteville and Galena Groups; and the Ancell aquifer, composed of sandstones of the Glenwood Formation and the St. Peter Sanstone. Water-level altitudes in the shallow drift aquifers generally follow surface topography. Analysis of water-level data does not clearly indicate overutilization of these aquifers. Water-level altitudes in the deep drift aquifers decrease from west to east. Comparison of historical depth to water measurements with current (1995) measurements indicates large decreases in water levels in some areas. The deep drift aquifers may be overutilized at these locations. Water-level altitudes in the Alexandrian-Maquoketa aquifer generally decrease from west to east. The potentiometric surface of the aquifer follows the bedrock-surface topography in some locations. Localized low water-level altitudes and large decreases in water levels indicate the Alexandrian-Maquoketa aquifer is overutilized in several areas. Water-level altitudes in the wells finished in the Galena- Platteville aquifer vary by more than 300 feet. Large decreases in water levels in wells finished in the Galena-Platteville aquifer indicate the Galena-Platteville and Alexandrian-Maquoketa aquifers are overutilized in the northern part of the township. Water-level altitudes in the wells finished in the Ancell aquifer are also highly variable. There is no indication that the Ancell aquifer is overutilized.

    2012-01-01

    Given the fact that 1.4 billion people, over 20% of the world’s population, lack access to electricity, rural electrification remains a common challenge for many developing countries. The ‘Township Electrification Program’ launched by the Chinese government in 2002 is known as the world’s largest renewable energy-based rural electrification program in terms of investment volume ever carried out by a country. This study gives an in-depth examination of the program implemented in two selected townships in remote of rural areas of western China. The results showed that the implementation of the program possessed a technical orientation (e.g., construction of stations, installation of systems), and underestimated the financial implications (e.g., electricity tariff, households’ ability to pay electricity fees, financial management) as well as human resources available (e.g., training for operators, household participation) and institutional capacity building (e.g., good governance, regulatory framework) at the local level. Even though electricity was provided by the solar PV power stations, households still relied on traditional energy sources, such as candles and dry cell batteries, due to the fact that electricity service was unreliable and electricity supply was not sufficient for households’ needs. - Highlights: ► China’s electrification rate has reached the level of OECD countries. ► Township Electrification Program is the world’s largest electrification program. ► The program possessed a technical orientation and underestimated other aspects. ► Households still relied on traditional energy, such as candles and batteries. ► Having electricity access did not mean that electricity was actually used.

    Protactinium-231 ( 231 Pa) occurs in nature as a member of the decay chain of naturally occuring 235 U of the 4n+ 3 radioactive series. The expected protactinium concentration in the Jaduguda ore body (with uranium concentration of 0.03-0.06 %) is around 0.2 parts per billion (ppb) and that in monazite ore (uranium concentration 0.3%) is 0.9 ppb. The process at uranium ore processing plant at Jaduguda was studied. 231 Pa content in samples from the process streams of the plant was determined. The gamma ray spectrometry method was chosen and standardised in our laboratory to detect and measure 231 Pa in parts per billion levels in these samples. A concentrated source of protactinium could not be found among the assessed streams of Jaduguda uranium plant. The Monazite processing plant at IRE, Aluva was then studied. From the known chemistry of protactinium, the possible distribution of the 231 Pa was guessed at. Accordingly, the process streams of IRE process plant were selected to prospect for 231 Pa and determine the fractionation of protactinium. For analysis of 231 Pa, the thorium bearing samples were chemically treated to remove the thorium daughter products, which interfere in gamma spectrometry. This report describes the planning for prospecting, sample selection, the standardisation of the analysis procedure for determination of 231 Pa content, and the analysis results. The 231 Pa content in various streams of Indian Rare Earths plant was found in the range 0.2 -6.5 ppb. Some of the streams did not carry any protactinium. The fractionation of 231 Pa in the various streams of the plant and the selection of source for recovery of protactinium are discussed in detail. (author)

    Full Text Available The new language curriculum in South Africa recommends that extended writing be taught through a combination of text-based (or genre and process approaches. This article reports on a study of the teaching and assessment of narrative writing in English as a first additional language (FAL at a time of curriculum change. The setting is a Cape Flats township school. In focusing on a story written by a Grade 9 learner and assessed by her teacher, the study sought evidence of the use of text-based and process approaches. The theoretical frame is informed by genre theory, which draws on Systemic Functional Linguistics and social constructivist approaches to language learning. A qualitative research paradigm was used. Data obtained for this case study included the learner’s writing, interviews with the teacher, and classroom observation. The study finds very little evidence of a scaffolded approach to the teaching and assessment of writing, and explores the constraints on the realisation of the curriculum cycle in English FAL. These relate to the teacher’s understanding of writing as well as to material conditions in township schools.

  15. Understanding teenage pregnancy in a post-apartheid South African township.

    2010-05-01

    Although South Africa's total fertility rate is one of the lowest in sub-Saharan Africa, high rates of early childbearing remain a concern. Most teenage pregnancies occur among poor black and coloured South Africans. The majority of these pregnancies are said to be unwanted and unplanned and the teenager's relationships, unstable. Becoming a mother during one's teenage years is perceived to be socially, economically and physically deleterious for the teenager and her baby. This paper presents ethnographic data collected over a five-year period in the South African township of Nyanga East in the Western Cape. It draws attention to the circumstances that surround teenage pregnancy and discusses reactions to teenage pregnancies in this community. Findings highlight that despite the negative perception of teenage pregnancy within the township, particular social and cultural circumstances provided fertile ground for its occurrence. Furthermore, the paper argues that in this particular community the management of a teenage pregnancy played a functional and critical role in maintaining and reproducing social norms and ideals regarding intergenerational relationships, which ultimately ensured that the rates of early childbearing remained high.

    In China, rural areas are a weak link of HIV/AIDS prevention and control. From September 2011, an innovative "county-township-village" allied intervention was implemented in Longzhou County, Guangxi, which assigned the tasks of HIV/AIDS prevention and control to the county Centers for Disease Control and Prevention (CDC), township hospitals, and village clinics, respectively, instead of traditional intervention in which the county CDC undertook the entire work. A 6-year consecutive cross-sectional survey, including 3-year traditional intervention (2009-2011) and 3-year innovative intervention (2012-2014), was conducted to evaluate the effects of the new intervention. Compared to traditional intervention, the innovative intervention achieved positive effects in decreasing risky behaviors. Among female sex workers, condom use rate in the last month increased from 72.06% to 96.82% (p ratio of HIV infection during innovative intervention was 0.631 (95% confidence interval 0.549-0.726) compared with traditional one. Cost-effectiveness analysis indicates that innovative intervention restores each disability-adjusted life year costing an average of $124.26. Taken together, Longzhou's innovative intervention has achieved good effects on HIV/AIDS prevention and control and provides a good reference for rural China.

    This study aims to describe betel quid chewing practice and compare oral potentially malignant disorders between chewers and non-chewers of betel quid among residents in Dagon Myothit (East) Township, Myanmar. The study used a cross-sectional design conducted with a representative sample of 542 adults aged 18 years and above in the township. The trained interviewers collected data using a pretested structured questionnaire. On-site oral examination was done for suspected oral lesions. The mean age of the respondents was 45 years and 59% were women. Fifty-two percent of the respondents were currently in the habit of chewing betel quids (72% of men and 39% of women). Among 284 current betel quid chewers, 240 (85%) chewed betel quids together with tobacco. Out of 284 current betel quid chewers, 24 (8.5%) were found to have oral potentially malignant disorders; out of 258 betel quid non-chewers, only 1 (0.4%) was found to have oral potentially malignant disorders. This highlights the growing importance of smokeless tobacco use as public health problem.

    Escalation of non-communicable diseases (NCDs) among urban South African populations disproportionately afflicted by HIV/AIDS presents not only medical challenges but also new ways in which people understand and experience sickness. In Soweto, the psychological imprints of political violence of the Apartheid era and structural violence of HIV/AIDS have shaped social and health discourses. Yet, as NCDs increasingly become part of social and biomedical discussions in South African townships, new frames for elucidating sickness are emerging. This article employs the concept of syndemic suffering to critically examine how 27 women living with Type 2 diabetes in Soweto, a township adjacent to Johannesburg known for socio-economic mobility as well as inequality, experience and understand syndemic social and health problems. For example, women described how reconstructing families and raising grandchildren after losing children to AIDS was not only socially challenging but also affected how they ate, and how they accepted and managed their diabetes. Although previously diagnosed with diabetes, women illustrated how a myriad of social and health concerns shaped sickness. Many related diabetes treatment to shared AIDS nosologies, referring to diabetes as 'the same' or 'worse'. These narratives demonstrate how suffering weaves a social history where HIV becomes ordinary, and diabetes new.

    Full Text Available Research overwhelmingly suggests that effective teaching and learning can occur only in a safe and secure school environment. However, despite the plethora of laws and acts protecting teachers and learners in South African schools, scores of them are still unsafe. This study examines the safety of teachers and learners in township secondary schools in the Free State province, South Africa. The sample of study consisted of 396 teachers who were randomly selected from 44 township secondary schools across the province. The sample completed a questionnaire based on the safety of teachers and learners in their schools. Prior to completion, the questionnaire was tested for reliability using the Cronbach alpha coefficient and it was found to have a reliability score of .885, indicating an acceptable reliability coefficient. The questionnaire was computer analysed using the Statistical Package for Social Sciences Primer Version 12. The results of the analysis revealed that both teachers and learners are not safe in their schools, either during or after school hours. The causes of a lack of safety in these schools reside within and without the schools, implying that learners are sometimes the culprits. The study concludes with recommendations on addressing the problem.

    Full Text Available Many learners living in townships require protection and resilience to overcome obstacles and adversities in their context of development. The literature on resilience indicates strongly that resilience is embedded systemically. In the absence of constructive and supportive conditions in the home environment, the school would logically appear to be the next resource in line to be tapped. We investigated the contribution of two South African township schools to the resilience of their middleadolescent learners. Case studies with focus groups of resilient and less-resilient Grade 9 learners were used, following the Interactive Qualitative Analysis method, to determine the participants' perceptions of how the school contributes to the degree and nature of their resilience. The influence of the school varied depending on the degree of the learners' resilience, but also depending on factors within the school itself, suggesting that schools play a distinctive and determining role. Contributions particularly highlighted included creation, or failure to create, a supportive teaching and learning environment with effective implementation of rules and educational policy to provide care and safety for its learners and develop them to reach their future goals. Resilient learners were more ready than less resilient learners to acknowledge and utilise these characteristics. All focus groups placed much emphasis on goal attainment, suggesting a strong relationship with resilience.

  2. Renewable Energy Use in Smallholder Farming Systems: A Case Study in Tafresh Township of Iran

    Full Text Available This study was conducted to investigate use of renewable energy and materials in smallholder farming system of the Tafresh township of Iran. The population of the study consisted of 2,400 small farmers working in the smallholder farming systems of the area, in which 133 people were selected as sample using Cochran formula and simple random sampling technique. In order to gather the information, a questionnaire was developed for the study and validated by the judgment of the experts in agricultural development and extension. The reliability of the main scales of the questionnaire was examined by Cronbach Alpha coefficients, which ranged from 0.7 to 0.93, indicating the tool of study is reliable. The findings revealed that the majority of the respondents use renewable energy and materials directly in its traditional forms without enabling technologies, and they lack the access to renewable technologies to improve the efficiency of energy use. They preferred fossil energy for many activities due to its lower cost and ease of access. The overall conclusion is that there are potentials and capacities for using renewable energies and materials in the farming systems of the Tafresh township. The government has to support and encourage the adoption of renewable technologies and abandon fossil fuels wherever possible.

  3. Applying spatial clustering analysis to a township-level social vulnerability assessment in Taiwan

    Full Text Available The degree of social vulnerability may vary according to the conditions and backgrounds of different locations, yet spatial clustering phenomena may exist when nearby spatial units exhibit similar characteristics. This study applied spatial autocorrelation statistics to analyze the spatial association of vulnerability among townships in Taiwan. The vulnerability was first assessed on the basis of a social vulnerability index that was constructed using Fuzzy Delphi and analytic hierarchy process methods. Subsequently, the corresponding indicator variables were applied to calculate standardized vulnerability assessment scores by using government data. According to the results of the vulnerability assessment in which T scores were normalized, the distribution of social vulnerabilities varied among the townships. The scores were further analyzed using spatial autocorrelation statistics for spatial clustering of vulnerability distribution. The Local G statistic identified 42 significant spatial association pockets, whereas the Global G statistic indicated no spatial phenomenon of clustering. This phenomenon was verified and explained by applying Moran's I statistics to examine the homogeneity and heterogeneity of spatial associations. Although both statistics were originally designed to identify the existence of spatial clustering, they serve diverse purposes, and the results can be compared to obtain additional insights into the distribution patterns of social vulnerability.

  4. Structure and activity of the Pseudomonas aeruginosa hotdog-fold thioesterases PA5202 and PA2801.

    The hotdog fold is one of the basic protein folds widely present in bacteria, archaea and eukaryotes. Many of these proteins exhibit thioesterase activity against fatty acyl-CoAs and play important roles in lipid metabolism, cellular signalling and degradation of xenobiotics. The genome of the opportunistic pathogen Pseudomonas aeruginosa contains over 20 genes encoding predicted hotdog-fold proteins, none of which have been experimentally characterized. We have found that two P. aeruginosa hotdog proteins display high thioesterase activity against 3-hydroxy-3-methylglutaryl-CoA and glutaryl-CoA (PA5202), and octanoyl-CoA (PA2801). Crystal structures of these proteins were solved (at 1.70 and 1.75 Å for PA5202 and PA2801 respectively) and revealed a hotdog fold with a potential catalytic carboxylate residue located on the long α-helix (Asp(57) in PA5202 and Glu(35) in PA2801). Alanine residue replacement mutagenesis of PA5202 identified four residues (Asn(42), Arg(43), Asp(57) and Thr(76)) that are critical for its activity and are located in the active site. A P. aeruginosa PA5202 deletion strain showed an increased secretion of the antimicrobial pigment pyocyanine and an increased expression of genes involved in pyocyanin biosynthesis, suggesting a functional link between PA5202 activity and pyocyanin production. Thus the P. aeruginosa hotdog thioesterases PA5202 and PA2801 have similar structures, but exhibit different substrate preferences and functions.

    Nadezhda V. Dashkovskaya

    2014-12-01

    Full Text Available In the present article the concept of legal custom as a source of law is researched. The role of legal customs in Russian Empire is shown. It is proved that during the Russian Empire period legal custom played an important role in the legal system, being one of the building blocks. Peculiarities of township courts activity are researched. Significance of legal customs for proceedings in the township courts is shown. For the importance of township courts in the Russian Empire played the fact that in their work they used existing among peasants customs and it was sanctioned by the authorities. Author stresses out that by recognizing custom, state thus authorizes current pattern of behavior in the society, a way of resolve conflicts that to the greatest extent are consistent with the understanding of justice by the society. To the legal custom, following features: custom is formed as a result of certain action frequent repetition; the source of the legal custom formation is a social consciousness; customs largely reflect the level of the society development at the particular stage; customs has quite a local character; customs reflect collective understanding on the fair nature of law. In the article two features which the judicial system of the Russian Empire had in the post-reform period: presence of class township courts as a class judiciary and application of legal customs to the township courts are noted. Combination of these two features allowed government to preserve patriarchal relations in the countryside. Such conservation, to some extent, was contrary to the liberal orientation of the "great reforms" of Alexander II, hindered development of the capitalist relations in the country, delaying implementation of the judicial reform principles.

  20. Japan's nuclear PA activity in local governments

    International Nuclear Information System (INIS)

    Fujii, Nobuyuki

    1995-01-01

    This presentation emphasises some points of PA activities, based on the experience of 'cooperation projects for local governments'. Local governments distribute the public information directly to the residents. This is very important because officers of the local government can be the opinion leaders of the region. Local government exist very close to the residents, while the central government is a distant and faceless existence for the local people. It is believed that the local governments play an imperative role in PA activities. In other words, we must further utilize the organizations and functions of the local governments to implement PA activities. In conclusion, three recommendations are offered. Firstly, enough budget and authority should be given to the local governments as far as PA activities in their areas are concerned, and most of such activities should be entrusted to the local governments. Local governments should place more public relations officers, and continue the manpower development. Second, with regard to highly technical or specialized issues which a local governments cannot treat alone, related organizations like JAERO should support their PA activities. Third, such related organizations should also cooperate with local government including assistance in providing know-how, when their public information activities focus on educators, journalists, or the women. These three points should be given due consideration in our cooperation projects for the local governments, and JAERO is doing its best every day

  1. Challenging Pentecostal moralism: erotic geographies, religion and sexual practices among township youth in Cape Town.

    Burchardt, Marian

    2011-06-01

    Research on constructions of sexuality in Pentecostalism often struggles with the fact that the research setting is defined ex ante in terms of church communities, which imposes upon ethnographic accounts the same limitations Pentecostal morality imposes upon church members' discourse. Taking young Pentecostals operating in a space that is not explicitly religious as the methodological entrance to the field, this paper explores negotiations over sexuality, intimate relationships and love among Xhosa-speaking township youth. It introduces the notion of erotic geographies to consider how possible influences of religious discourses on sexuality are refracted by alternative cultural orientations and material contexts. Findings suggest that premarital abstinence appears as a highly exceptional ideal for youth. Even among Pentecostal youth, notions of sexuality are largely severed from religiosity and faithfulness and romanticism are dominant ideals. Future research on Pentecostalism and sexuality should be less religious-centric and rooted more firmly in ethnographies of youth sexual cultures.

    China has experienced dramatic industrialization, urbanization, and economic growth over the last 3 decades. The rapid transformation and dramatic prosperity of industries in rural areas have, in turn, created tremendous challenges for occupational health and safety (OHS). This article was prepared to address occupational health and safety issues in township- and village-owned enterprises (TVEs) from several aspects, including working conditions and workplace hazards, major recognized OHS problems, implications of TVE industries to environmental health, and migrant workers. Among the major recognized OHS problems, pneumoconiosis, chemical poisoning, and workplace accidents, especially in small-scale coal mines, are highlighted. It is suggested that the national polices and regulations that specifically target TVEs are indispensable and a more powerful administrative structure should be established to ensure that the pertinent polices, regulations, and OHS standards can be enforced widely and effectively in practice.

  5. Engineering feasibility analysis for in-situ stabilization of Burrell Township site residues

    International Nuclear Information System (INIS)

    1982-11-01

    The Burrell Township site, located in western Pennsylvania, received approximately 11,600 tons of radioactively-contaminated material in late 1956 and early 1957 from the Vitro Manufacturing Company's operations in Canonsburg, Pennsylvania. WESTON was requested to conduct an engineering study to determine the feasibility of stabilizing the site in accordance with the US Environmental Protection Agency's (EPA) interim and proposed standards (45 FR 27366--27368, April 22, 1980, and 46 FR 2556--2563, January 9, 1981). The scope of this study is limited to those alternatives that can be implemented on the site and will not require removal and offsite disposal of radioactively-contaminated material. Four alternatives for control of the radioactive material at the Burrell site were considered and evaluated, as follows: 1. Site stabilization and closure. 2. Site control and containment. 3. Waste excavation and encapsulation. 4. Waste excavation, incineration, and encapsulation. 2 refs., 32 figs., 12 tabs

    The existing study of proper carrying capacity (PCC) has mostly focused on province or county administrative units, which can only macroscopically master the quantitative characteristics of PCC, but could not effectively take some animal husbandry management measures that are pertinent and operational. At town-scale, this paper used CASA model to estimate the PCC in Mongolian Autonomous County of Henan, Qinghai province, China,with serious grassland degeneration that mainly caused by overgrazing. The results showed that the PCC throughout the County was 950,417 sheep unit. For the township, the PCC of Saierlong and Duosong were the largest (247,100 sheep unit) and the smallest (82,016 sheep unit) respectively. This study will provide reference data for developing sustainable development of town-scale pasture policies and also will help to evaluate the health status of the alpine grassland ecosystem on Qinghai-Tibet plateau.

    During the early 1980s the W. R. Grace site and the adjacent area were the focus of several radiological investigations. Radiological surveys revealed surface radionuclide concentrations greater than those acceptable under US Department of Energy (DOE) remedial action guidelines. In 1984, Congress assigned responsibility for cleanup of the W.R. Grace site to the Department of Energy. The property was redesignated as the Wayne Interim Storage Site (WISS) and in 1985 DOE began plans for survey/monitoring, and remedial action of nearby vicinity properties and the interim storage site. Evaluations of the radiological survey data in 1986 indicated radioactive contamination above current DOE guidelines at the off-site areas of parts of Township Park southwest of WISS, and parts of the Sheffield Brook area and railroad siding in Pequannock Township. Remedial action was conducted over several years of most of these areas and independent verification of remedial action was performed. A team from Oak Ridge National Laboratory conducted a mobile radiological scanning survey of a stretch of public roadway in the immediate vicinity south of the WISS, extending northwest to the Pompton turnpike. A mobile gamma scanning van with an on-board computer system was used to identify at least 24 anomalous areas, some attributable to the naturally elevated levels in concrete, asphalt, and natural granite found in streets, driveways and landscaping materials in the area. Analyses of the biased soil samples taken in the ballpark also revealed slightly elevated thorium concentrations. However, soil concentration measurements when averaged over 100 m 2 fall below the limits prescribed by DOE radiological guidelines established for this site. The anomalies may result from a wide range of sources, such as ash, granite, and fertilizer as well as materials from the former Grace facility

    Full Text Available Purpose. Our physiopathological assumption is that u-PA, t-PA, and PAI-1 are released by calcified aortic valves and play a role in the calcification of these valves. Methods. Sixty-five calcified aortic valves were collected from patients suffering from aortic stenosis. Each valve was incubated for 24 hours in culture medium. The supernatants were used to measure u-PA, t-PA, and PAI-1 concentrations; the valve calcification was evaluated using biphotonic absorptiometry. Results. Aortic stenosis valves expressed normal plasminogen activators concentrations and overexpressed PAI-1 (u-PA, t-PA, and PAI-1 mean concentrations were, resp., 1.69 ng/mL ± 0.80, 2.76 ng/mL ± 1.33, and 53.27 ng/mL ± 36.39. There was no correlation between u-PA and PAI-1 (r=0.3 but t-PA and PAI-1 were strongly correlated with each other (r=0.6. Overexpression of PAI-1 was proportional to the calcium content of the AS valves. Conclusions. Our results demonstrate a consistent increase of PAI-1 proportional to the calcification. The overexpression of PAI-1 may be useful as a predictive indicator in patients with aortic stenosis.

    The purpose of this Analysis/Model Report (AMR) is to document the predictions and analysis performed using the Seepage Model for Performance Assessment (PA) and the Disturbed Drift Seepage Submodel for both the Topopah Spring middle nonlithophysal and lower lithophysal lithostratigraphic units at Yucca Mountain. These results will be used by PA to develop the probability distribution of water seepage into waste-emplacement drifts at Yucca Mountain, Nevada, as part of the evaluation of the long term performance of the potential repository. This AMR is in accordance with the ''Technical Work Plan for Unsaturated Zone (UZ) Flow and Transport Process Model Report'' (CRWMS M andO 2000 [153447]). This purpose is accomplished by performing numerical simulations with stochastic representations of hydrological properties, using the Seepage Model for PA, and evaluating the effects of an alternative drift geometry representing a partially collapsed drift using the Disturbed Drift Seepage Submodel. Seepage of water into waste-emplacement drifts is considered one of the principal factors having the greatest impact of long-term safety of the repository system (CRWMS M andO 2000 [153225], Table 4-1). This AMR supports the analysis and simulation that are used by PA to develop the probability distribution of water seepage into drift, and is therefore a model of primary (Level 1) importance (AP-3.15Q, ''Managing Technical Product Inputs''). The intended purpose of the Seepage Model for PA is to support: (1) PA; (2) Abstraction of Drift-Scale Seepage; and (3) Unsaturated Zone (UZ) Flow and Transport Process Model Report (PMR). Seepage into drifts is evaluated by applying numerical models with stochastic representations of hydrological properties and performing flow simulations with multiple realizations of the permeability field around the drift. The Seepage Model for PA uses the distribution of permeabilities derived from air injection testing in niches and in the cross drift to

    The Cementitious Barriers Partnership (CBP) is a collaborative program sponsored by the US DOE Office of Waste Processing. The objective of the CBP is to develop a set of computational tools to improve understanding and prediction of the long-term structural, hydraulic, and chemical performance of cementitious barriers and waste forms used in nuclear applications. CBP tools are expected to better characterize and reduce the uncertainties of current methodologies for assessing cementitious barrier performance and increase the consistency and transparency of the assessment process, as the five-year program progresses. In September 2009, entering its second year of funded effort, the CBP sought opportunities to provide near-term tangible support to DOE Performance Assessments (PAs). The Savannah River Saltstone Disposal Facility (SDF) was selected for the initial PA support effort because (1) cementitious waste forms and barriers play a prominent role in the performance of the facility, (2) certain important long-term behaviors of cementitious materials composing the facility are uncertain, (3) review of the SDF PA by external stakeholders is ongoing, and (4) the DOE contractor responsible for the SDF PA is open to receiving technical assistance from the CBP. A review of the current (SRR Closure & Waste Disposal Authority 2009) and prior Saltstone PAs (e.g., Cook et al. 2005) suggested five potential opportunities for improving predictions. The candidate topics considered were (1) concrete degradation from external sulfate attack, (2) impact of atmospheric exposure to concrete and grout before closure, such as accelerated slag and Tc-99 oxidation, (3) mechanistic prediction of geochemical conditions, (4) concrete degradation from rebar corrosion due to carbonation, and (5) early age cracking from drying and/or thermal shrinkage. The candidate topics were down-selected considering the feasibility of addressing each issue within approximately six months, and

    This article explores the politics of representing Black queer and trans subjectivities in the recent documentary film and photography of South African lesbian visual activist Zanele Muholi. While Muholi's work has been most often been positioned as an artistic response to the hate-crimes and violence perpetuated against Black lesbians in South African townships, most notably acts of sexual violence known increasingly as corrective rape, I argue that Muholi's documentary texts trouble the spatial, gendered, and highly racialized articulations that make up an increasingly global corrective rape discourse. The article considers how her visual texts foreground and (re)visualize Black queer and trans gender experiences that relocate, challenge, collaborate with, and at times, perform, masculinity as means to subvert heterosexist and racist constructions of township space and the Black gendered body.

    Full Text Available Factors that contribute to resilience are key to the positive development of youths, and knowledge of such factors is essential for promoting resilience in schools through both policy and practice. This study reports on the results of an item and factor analysis of the Resilience Questionnaire for Middle-adolescents in Township Schools (R-MATS that was used to survey 291 Grade 9 middle-adolescent learners from two black-only township secondary schools. The majority of respondents indicated an overall sense of contending with various stressors, especially the exposure to violence, and academic challenges. Respondents attributed their buoyancy to individual and environmental factors, such as self-confidence, an internal locus of control, a tough personality, commitment, being achievement-oriented, as well as positive identification of and access to social support.

    China's rapid transition in healthcare service system has posed considerable challenges for the primary care system. Little is known regarding the capacity of township hospitals (THs) to deliver surgical care in rural China with over 600 million lives. We aimed to ascertain its current performance, barriers, and summary lessons for its re-building in central China. This study was conducted in four counties from two provinces in central China. The New Rural Cooperative Medical System (NRCMS) claim data from two counties in Hubei province was analyzed to describe the current situation of surgical care provision. Based on previous studies, self-administered questionnaire was established to collect key indicators from 60 THs from 2011 to 2015, and social and economic statuses of the sampling townships were collected from the local statistical yearbook. Semi-structured interviews were conducted among seven key administrators in the THs that did not provide appendectomy care in 2015. Determinants of appendectomy care provision were examined using a negative binominal regression model. First, with the rapid increase in inpatient services provided by the THs, their proportion of surgical service provision has been nibbled by out-of-county facilities. Second, although DY achieved a stable performance, the total amount of appendectomy provided by the 60 THs decreased to 589 in 2015 from 1389 in 2011. Moreover, their proportion reduced to 26.77% in 2015 from 41.84% in 2012. Third, an increasing number of THs did not provide appendectomy in 2015, with the shortage of anesthesiologists and equipment as the most mentioned reasons (46.43%). Estimation results from the negative binomial model indicated that the annual average per capita disposable income and tightly integrated delivery networks (IDNs) negatively affected the amount of appendectomy provided by THs. By contrast, the probability of appendectomy provision by THs was increased by performance-related payment (PRP). Out

    Full Text Available Workplace violence in Chinese township hospitals is a major public health problem. We identified the risk factors of healthcare workers’ worry about experiencing workplace violence in 90 Chinese township hospitals and determined specific measures for differing stages of violence (based on crisis management theory. Participants were 440 general practitioners and 398 general nurses from Heilongjiang Province, China (response rate 84.6%. One hundred and six (12.6% respondents reported being physically attacked in their workplace in the previous 12 months. Regarding psychological violence, the most common type reported was verbal abuse (46.0%. While most (85.2% respondents had some degree of worry about suffering violence, 22.1% were worried or very worried. Ordinal regression analysis revealed that being ≤35 years of age, having a lower educational level, having less work experience, and working night shifts were all associated with worry about workplace violence. Furthermore, those without experience of such violence were more likely to worry about it. Respondents’ suggested measures for controlling violence included “widening channels on medical dispute solutions,” “improving doctor-patient communication,” and “advocating for respect for medical workers via the media.” Results suggest the target factors for reducing healthcare workers’ worry by according to the type of education and training and possible measures for limiting workplace violence in township hospitals.

    2016-09-01

    Full Text Available Despite improvements in educational provision in South Africa since 1994, the opportunities for learners from historically under-resourced schools to gain access to powerful English resources remain limited and unequal (Prinsloo 2012. In this article I will provide a detailed description of literacy practices in a township high school in Cape Town, specifically of the orientations to text that are made available to learners. I will draw on feminist poststructuralist theory, in which the subject is theorised as constructed and contested in language to construct difference. The analysis of classroom discourse and text-based tasks shows that the orientations to reading that were offered were characterised by a focus on the surface meaning of the texts and by an absence of critical engagement, despite the latter being required in the new Curriculum and Assessment Policy Statement. The analysis reveals how the power dynamics of our racialised past and dominant ideologies about gender, class and race continue to define teaching in our classrooms in ways that limit access to the English resources that learners in under-resourced schools need for academic success.

    This article reports on a research study done in Katutura Township, near Windhoek. A qualitative, exploratory, descriptive and contextual design was followed to answer the research question investigating experiences of mothers caring for mentally retarded children at home. Phenomenological interviews were conducted with a purposefully selected sample of twelve mothers. The meaning of their experiences was analysed by using Teschxs method (1990 in Creswell, 1994:155) of analysing qualitative data. The results indicated various emotions and challenges experienced by these mothers during the care of their children. Feelings of shock, despondency and sadness dominated the early stages when the retarded children were still young. During later years, as the children were growing up, the mothers felt shame, fear, frustration, anger, disappointment and worry. However, acceptance followed, as the children grew older. Stigma seemed to affect all the respondents. Support in any form or lack thereof seemed to be the decisive factor-positioning mothers along a continuum of two extremes, namely despairing isolation and integrated happiness. Recommendations were made regarding the improvement of heath care services and education of the mothers and their families.

    A new energy vision was established in the Iwaizumi Township area in Iwate Prefecture. The heat energy consumed by each household in Iwaizumi Town is 20.5 two-hundred-liter drums, while transportation (railways, buses, trucks and private cars) consumes 12.2 drums annually, and the electric energy field 4.7 drums annually. As the town as a whole, the ratio of utilization as heat energy is relatively high. Therefore, new energy introduction should be focused importantly on use of solar heat hot water supply device and high-level utilization of forestry fuels. The new energy introduction project includes introduction of bio-mass energy to produce heat energy and electric power using livestock excreta, cut woods, thinned woods, and kitchen refuses as the resources, structuring a new energy model for the 'Communication Land Iwaizumi', activation of the central urban area by introducing micro hydropower generation, assistance to proliferation of new energies to town-operated houses, households, and business entities, introduction of new energies into the disaster prevention center, schools, and insurance, medical and welfare facilities, introduction of clean energy automobiles, and uplift of consciousness of town people.

    The purpose of this case study was to relate part of the journey to appropriate education for two young children with physical disabilities in a low socio-economic peri-urban informal settlement - or 'township' - in South Africa. The part of the on-going journey described here spanned four-and-a-half years and included the two children, their families, their teachers, their community and a small team of rehabilitation professionals working for a non-profit organisation in the area. The rehabilitation professionals' goals were to provide support for the children, their families, their current special care centre and the school(s) they would attend in the future. The steps from the special care centre, to a mainstream early childhood development (ECD) centre for both of them, and then on to (a) a school for learners with special educational needs (LSEN) for one child and (b) a mainstream primary school for the other, are described. Challenges encountered on the way included parental fears, community attitudes and physical accessibility. Practical outcomes included different placements for the two children with implications and recommendations for prioritised parent involvement, individual approaches, interdisciplinary and community-based collaborations. Recommendations are given for clinical contexts, curricula and policy matters; for research and for scaling up such a programme through community workers.

    Full Text Available The aim of this study was to investigate the action of rangeland-depended livestock holders regarding rangeland conservation, including protection and rehabilitation activities and to analyse relevant influencing factors, using a mixed method of survey and case study. The data were collected through analysing existing documents, focus groups, semi-structured and structured interviews using questionnaires submitted to 204 rural livestock holders in the Mahneshan Township. The quantitative data were analysed using SPSS and AMOS software. According to the results farmers’ knowledge regarding the role, importance and factors affecting rangeland degradation was relatively high, however they had a low level of knowledge and action about mechanical conservation techniques. The action of livestock holders in terms of biological conservation activities and grazing management showed a positive and signifincat corrletaion with variables such as implementing of rangeland projects, their interaction with external institutions, participating in extension training courses, education level and irrigated and rainfed agricultural land size. Moreover, based on a path analysis, 37% of the variance of the farmers’ actions regarding the rangeland conservation was explained by the variables such as rangeland rehabilitation actions, farmers’ conservation knowledge, farmers’ interaction with natural resources experts, beekeeping, and participating in extension training courses. Promotional and extension activities and farmers’ interaction with experts have a positive effect in enhancing farmers’ knowledge and actions for sustainable rangeland use and conservation.

    Full Text Available Testing soil  is recognized to be an important practice for sustainable use of nutrients, which has been introduced to Iranian grape farmers as an innovation for over a decade. Its adoption and utilization may be influenced by receiving information from different sources. This study is performed to introduce these information sources that may influence the adoption of soil testing innovation by grape farmers. Using a survey, a sample of 260 out of 3942 grape farmers of the Khorramdarreh Township was selected using a stratified sampling technique and data was collected by structured interviews using a questionnaire. The content and face validity of the questionnaire was discussed and reviewed by a panel of experts consisting of university staff and agricultural professionals. Its reliability was also assessed through a pilot study and its main constructs were approved to be reliable using the Cronbach’s alpha test (measures between 0.71 and 0.84. Less than half of the grape farmers conducted soil testing in their vineyards. A regression analysis showed that variables such as contact of the farmers with model grape producers, Poster Received, publications and listening to radio programs and farmers’ education have a significant positive impact on soil testing innovation adoption. Therefore, both interpersonal and mass media can have a positive effect on farmers to adopt this innovation.

    Betel nut chewing can cause precancerous oral lesions and is common in Myanmar. We conducted a cross sectional study aimed to estimate prevalence and factors influencing betel nut chewing among 420 subjects aged ≥18 years in West Insein Township, Yangon, Myanmar in order to inform preventive health programs. The mean age of the study subjects was 45(±15) years. The overall prevalence of current betel nut chewing among study subjects was 55.2%. The mean age starting betel nut chewing was 29(±13) years, and the mean duration of chewing was 15(±13) years. The reasons given by study subjects for chewing betel nut included the addictive effect to betel nut, to release tension, to get rid of boredom and to stop smoking. Sixty-two point three percent of current betel nut chewers also chewed tobacco and 24.2% also smoked cigarettes. Factors significantly associated with betel nut chewing were male gender, current alcohol consumer, having no education or finishing primary or secondary school, having a low score regarding their attitude about the health effects of betel nut chewing, and having high score on interpersonal factors by family and peer pressure. Our results show a need to better educate the public about the health effects of betel nut chewing among the study population.

A total of 327 households and 1491 members were included in the study. Aedes larval indices detected in this study were 25.7% for house index, 15.5% for container index and 48.0% for Breteau index. The occurrence of DHF among households and family members were 2.1% (95% CI: 0.9%, 4.4% and 0.6% (95% CI: 0.3%, 1.1%, respectively. The occurrence was highest among 5 to 14 years age-group. No case was reported among persons with equal or more than 60 years of age. Mortality and case fatality rates were 0% during study period. Larval positivity among households was significantly related to sufficiency of family income and number of water container they have. Surveillance and control procedures for both DHF and vector should be intensified in urban area. Awareness and participation of the community in prevention and control of DHF should also be raised. Socioeconomic status as well as proper water supply and storage should be improved in urban area.

    2014-11-01

    Objectives: This research determines to what extent ICT is adopted by MSBs in Soweto, and whether or not a positive correlation exists between the adoption rate of ICT and the financial and growth performance of the MSB itself. Method: A structured questionnaire was completed by 978 respondents to determine the extent of ICT adoption and for what ICT is used. This exploratory research provides new knowledge about the acceptance of ICT within township MSBs. Results: The results indicate that ICT is not used to the fullest by MSBs. Rather, it is used as a basic tool for doing business but it does not form an integral part of the business. This research provides insight into the usage and adoption of ICT and it opens the door for further cross-analysis research. Conclusion: Education and training are needed to ensure that MSBs use ICT to the fullest. MSBs embracing ICT can evolve from a survivalist SME to a more sustainable micro and small MSB.

The purpose of study is to identify and analyze the various opportunities viz., installation of solar water heater, energy efficient lighting, energy efficient air conditioners, and energy efficient submersible water pumps in desert coolers and thus achieve a considerable (65.7 %) reduction in GHG emissions. Out of the various opportunities considered, the retrofitting with solar water heater can be recommended for CDM. Though, the retrofitting with energy efficient lighting, energy efficient air conditioners and energy efficient submersible water pumps in desert coolers claimed CO2 emission reduction of 104.84, 25.92, and 36.94 tons per annum, respectively, but the only opportunity which got through CDM was retrofitting with solar water heater claiming 115.70 tCO2 (100 %) emission reductions per annum which could result into net earnings of 115.70 CERs. The simple and discounted payback period for all four project activities are also calculated with and without CDM and tax benefits.

    Full Text Available I reflect on the methodological processes underpinning a dissertation that investigated male learners' reasons for leaving high school early and the strategies they employed to negotiate everyday life. A qualitative case study was conducted with nine male early high school leavers between the ages of 18 and 25, as well as 12 stakeholders involved in the Orange Farm Township, south of Johannesburg. Purposive and snowball sampling techniques were used. Data were collected through in-depth interviews, document reviews, and observations. Narrative analysis revealed complications related to the notions of space and place of the potential participants and the researcher. In the first place, the difficulty was not in identifying participants, but in establishing rapport to the extent that they agreed to participate in the research. Assumptions about space and place gave rise to expectations that had to be managed, and consequently the researcher had to rethink the methodological choices. In particular, participants' perceived real social positions and their relation to different social spaces had to be negotiated. It is suggested that relatively novice researchers, researching male early high school leaving in familiar spaces, can mitigate complications of space, place and stigma during fieldwork by using multiple sources of data and strategic, flexible interviewing techniques.

    Full Text Available The study reported here used household level data toanalysedeterminants ofhousehold poverty amongst female-headed households in a South AfricanTownship of Bophelong. Poverty is defined and then measured for the sampledpopulation. A Logistic regression was estimated based on this data with theeconomic status (that is poor and non-poor as the dependent variable and a set ofdemographic variables as explanatory variables. The results show that householdsize, the age and employment status of theheadof householdsignificantly explainvariations in the likelihood of being poor.Household size was positivelyassociated with the probability of being poor, whereas the age and employmentstatus of the head of the household reduces the probability ofbeing in the poorcategory.It is of interest to note that the educational attainment of the householdhead is not important in reducing the chances of being a poor household.Information provided through this study is at household level and extends onexisting findings on poverty in South Africa bymodellingand determining thevarious socio-economic and demographic household level indicators responsiblefor female poverty.

    Unlike large firms with management teams, small businesses are usually run by one key person, the owner-entrepreneur, who bears almost all of the risks and makes almost all of the decisions related to the business. Because the owner-entrepreneur also embodies most of the firm-specific knowledge capital, health of the owner-entrepreneur is an important factor in the production process. Following a cohort of respondents in townships around Durban, South Africa, over a three-year period, we examined the relationship between an individual's physical health and the decision to start a business. Our results suggest that respondents who were recent business entrants were in better health than respondents who did not start new businesses. Moreover, respondents without a business at the beginning of the study who later opened businesses during the three-year study interval were significantly more likely to have better baseline health than those respondents who never started a new business. Hence, good health among entrepreneurs seems to be an important prerequisite to small business entry.

    While men who have sex with men (MSM) in Africa are at high risk for HIV infection, few of those already infected know their status. Effectively promoting frequent HIV testing-of increasing importance with the expanding accessibility of antiretroviral treatment-requires an understanding of the testing practices in this population. To understand men's HIV testing practices, including their behavior, experiences, and perceptions, we conducted in-depth interviews with 81 black South African MSM (ages 20-39), purposively recruited from four townships. Many men in the sample had tested for HIV. While ever having tested seemed to facilitate repeat testing, men still expressed a high level of discomfort with testing. It was common to test after having engaged in risky behavior, thus increasing anxiety about testing that was already present. Fear that they might test HIV positive caused some men to avoid testing until they were clearly sick, and others to avoid testing completely. HIV testing may increase in this population if it becomes a routine practice, instead of being driven by anxiety-inducing incidents. Mobilization through social support might facilitate frequent testing while education about current treatment options is needed.

    This illustrated final report for the Swiss Federal Office of Energy (SFOE) presents the results of a project concerning the energy consumption of various residential districts in cities and in rural townships. The analysis examines the consumption of primary energy by residential buildings, their supply and disposal infrastructures and that of traffic induced by settlements. Also, grey energy: consumption for the construction, renovation and demolition of buildings and infrastructures as well as the consumption of primary energy for the production and disposal of individual motor vehicle traffic and public transport is reviewed. Four Swiss case studies are dealt with including largely homogenous residential districts in Effretikon, Oetwil am See, Uster and the City of Zurich. The results of the analyses made are presented in graphical form. The authors quote the great potential for the reduction of the consumption of settlement-dependent primary energy that lies in the fields of energy-efficiency of buildings, mobility and power consumption. The report is rounded off with a comprehensive appendix.

    To study the factors that influence the family planning practice among married, reproductive age women in Hlaing Township, Myanmar. Cross-sectional survey research was conducted among 284 married, reproductive age women using stratified random sampling. The data were collected through questionnaire interviews during February and March 2012 and analyzed by frequency, percentage, Chi-square test, and multiple logistic regression. The proportion of families practicing family planning was 74.7%, contraceptive injection being the most commonly used method. The factors influencing family planning practice were attitude towards family planning, 24-hour availability of family planning services, health worker support, and partner and friends support. The women with a positive attitude toward family planning practiced family planning 3.7 times more than women who had a negative attitude. If family planning services were available for 24 hours, then women would practice 3.4 times more than if they were not available for 24 hours. When women got fair to good support from health workers, they practiced 15.0 times more on family planning and 4.3 times more who got fair to good support from partners and friends than women who got low support. The factors influencing family planning practice of married, reproductive age women were attitude toward family planning, 24-hour availability of family planning services, health worker support, and partner and friends support. The findings suggest that empowerment of health workers, training of volunteers, pharmacists and contraceptive drug providers, encouraging inter-spousal communication, and peer support, as well as an integrated approach to primary health care in order to target different populations to change women's attitudes on family planning, could increase family planning practice among Myanmar women.

    Objective Township hospitals (THs) are important components of the three-tier rural healthcare system of China. However, the efficiency and productivity of THs have been questioned since the healthcare reform was implemented in 2009. The objective of this study is to analyse the efficiency and productivity changes in THs before and after the reform process. Setting and participants A total of 48 sample THs were selected from the Xiaogan Prefecture in Hubei Province from 2008 to 2014. Outcome measures First, bootstrapping data envelopment analysis (DEA) was performed to estimate the technical efficiency (TE), pure technical efficiency (PTE) and scale efficiency (SE) of the sample THs during the period. Second, the bootstrapping Malmquist productivity index was used to calculate the productivity changes over time. Results The average TE, PTE and SE of the sample THs over the 7-year period were 0.5147, 0.6373 and 0.7080, respectively. The average TE and PTE increased from 2008 to 2012 but declined considerably after 2012. In general, the sample THs experienced a negative shift in productivity from 2008 to 2014. The negative change was 2.14%, which was attributed to a 23.89% decrease in technological changes (TC). The sample THs experienced a positive productivity shift from 2008 to 2012 but experienced deterioration from 2012 to 2014. Conclusions There was considerable space for TE improvement in the sample THs since the average TE was relatively low. From 2008 to 2014, the sample THs experienced a decrease in productivity, and the adverse alteration in TC should be emphasised. In the context of healthcare reform, the factors that influence TE and productivity of THs are complex. Results suggest that numerous quantitative and qualitative studies are necessary to explore the reasons for the changes in TE and productivity. PMID:27836870

    Full Text Available In this article, we report on a study that examined the active and receptive English vocabulary of two different groups of Grade 3 learners in South African township schools. The groups consisted of English Home Language (HL learners in the Western Cape and Xhosa HL and English First Additional Language (FAL learners in the Eastern Cape. The purpose was to document their different vocabulary trajectories during Grade 3. The Woodcock-Muñoz Language Survey was used to measure the active vocabulary levels of 118 learners at the beginning and the end of the school year. Another 284 learners from the same eight Grade 3 classes participated in a receptive vocabulary test at the end of the year. This test assessed their knowledge of the 60 most frequent words that occur in South Africa Grade 4 English textbooks. Results showed that although the HL learners knew almost double the number of words their English FAL peers did, both groups of learners increased their active word knowledge through the year by about 9%. Regarding their receptive vocabulary, the English FAL learners on average only knew 27% of the most frequent words at the end of their Grade 3. No significant gender differences were found. Learners in both language groups who were above their grade age had significantly lower scores than their younger peers. This confirms findings that children who start school with weak language skills tend to stay weak. Finally, initial active vocabulary knowledge was found to be a strong predictor of vocabulary development during the school year.

    Evaporation residues produced in the reaction 40Ar(176 MeV) + 181Ta were separated from the primary beam by the velocity filter SHIP and detected by a ΔE-E counter telescope. The technique of delayed coincidences was applied to individually identify the reaction products implanted into a Si-surface barrier detector by their subsequent alpha decays. The previously unknown nucleus 218Pa was identified by its known daughter decays. 218Pa was found to decay with Esub(α) = (9.614 +- 0.015) MeV, T(1/2) = (140 +- 50) μs and probably also with Esub(α) = (9.535 +- 0.020) MeV, T(1/2) = (150 + 100 - 50) μs. The half-life of the 8.33 MeV alpha decay of 217Pa was determined to be (o.2 +- 0.4) ms. Anew isomer in 217 Pa was found which decays with Esub(α) = (10.16 +- 0.02) MeV and T(1/2) = (1.8 +- 0.5) ms.

  14. Indoor social networks in a South African township: potential contribution of location to tuberculosis transmission.

    Directory of Open Access Journals (Sweden)

    Robin Wood

    Full Text Available We hypothesized that in South Africa, with a generalized tuberculosis (TB epidemic, TB infection is predominantly acquired indoors and transmission potential is determined by the number and duration of social contacts made in locations that are conducive to TB transmission. We therefore quantified time spent and contacts met in indoor locations and public transport by residents of a South African township with a very high TB burden.A diary-based community social mixing survey was performed in 2010. Randomly selected participants (n = 571 prospectively recorded numbers of contacts and time spent in specified locations over 24-hour periods. To better characterize age-related social networks, participants were stratified into ten 5-year age strata and locations were classified into 11 types.Five location types (own-household, other-households, transport, crèche/school, and work contributed 97.2% of total indoor time and 80.4% of total indoor contacts. Median time spent indoors was 19.1 hours/day (IQR:14.3-22.7, which was consistent across age strata. Median daily contacts increased from 16 (IQR:9-40 in 0-4 year-olds to 40 (IQR:18-60 in 15-19 year-olds and declined to 18 (IQR:10-41 in ≥45 year-olds. Mean daily own-household contacts was 8.8 (95%CI:8.2-9.4, which decreased with increasing age. Mean crèche/school contacts increased from 6.2/day (95%CI:2.7-9.7 in 0-4 year-olds to 28.1/day (95%CI:8.1-48.1 in 15-19 year-olds. Mean transport contacts increased from 4.9/day (95%CI:1.6-8.2 in 0-4 year-olds to 25.5/day (95%CI:12.1-38.9 in 25-29 year-olds.A limited number of location types contributed the majority of indoor social contacts in this community. Increasing numbers of social contacts occurred throughout childhood, adolescence, and young adulthood, predominantly in school and public transport. This rapid increase in non-home socialization parallels the increasing TB infection rates during childhood and young adulthood reported in this

  15. Public-health and individual approaches to antiretroviral therapy: township South Africa and Switzerland compared.

    2008-07-01

    Full Text Available The provision of highly active antiretroviral therapy (HAART in resource-limited settings follows a public health approach, which is characterised by a limited number of regimens and the standardisation of clinical and laboratory monitoring. In industrialized countries doctors prescribe from the full range of available antiretroviral drugs, supported by resistance testing and frequent laboratory monitoring. We compared virologic response, changes to first-line regimens, and mortality in HIV-infected patients starting HAART in South Africa and Switzerland.We analysed data from the Swiss HIV Cohort Study and two HAART programmes in townships of Cape Town, South Africa. We included treatment-naïve patients aged 16 y or older who had started treatment with at least three drugs since 2001, and excluded intravenous drug users. Data from a total of 2,348 patients from South Africa and 1,016 patients from the Swiss HIV Cohort Study were analysed. Median baseline CD4+ T cell counts were 80 cells/mul in South Africa and 204 cells/mul in Switzerland. In South Africa, patients started with one of four first-line regimens, which was subsequently changed in 514 patients (22%. In Switzerland, 36 first-line regimens were used initially, and these were changed in 539 patients (53%. In most patients HIV-1 RNA was suppressed to 500 copies/ml or less within one year: 96% (95% confidence interval [CI] 95%-97% in South Africa and 96% (94%-97% in Switzerland, and 26% (22%-29% and 27% (24%-31%, respectively, developed viral rebound within two years. Mortality was higher in South Africa than in Switzerland during the first months of HAART: adjusted hazard ratios were 5.90 (95% CI 1.81-19.2 during months 1-3 and 1.77 (0.90-3.50 during months 4-24.Compared to the highly individualised approach in Switzerland, programmatic HAART in South Africa resulted in similar virologic outcomes, with relatively few changes to initial regimens.

  17. The potential and reality of the solar water heater programme in South African townships: Lessons from the City of Tshwane

    International Nuclear Information System (INIS)

    Curry, Claire; Cherni, Judith A.; Mapako, Maxwell

    2017-01-01

    The South African solar water heater (SWH) programme is part of national policy to improve the country's electricity security, an innovative strategy to provide indigent households with free solar water heaters. The study assesses the effects of the government programme for poor townships on reduction of household electricity consumption, decline in energy poverty, and reduction in CO2 emissions; and estimates the impact of SWH on reducing electricity demand nationwide. It reports results from fieldwork carried out in the City of Tshwane to measure both quantitatively and qualitatively the success of the project's deployment in townships. Although households register average savings of 27% on their monthly electricity bills and off-peak electricity demand has reduced significantly in the area, a variety of problems prevented the project from attaining the desired level of impact. Difficulties encountered include technical faults with the heaters combined with nonavailability of maintenance; a rise in water consumption; lack of community engagement leading to apathy; and dearth of owner training leading to underuse. The gap between inflated estimates and real savings is discussed. Expanding the programme could generate jobs but significant challenges remain. - Highlights: • The government's aim of saving electricity and reducing utility bills partly achieved. • Savings of electricity are estimated at about 25% less than the potential saving. • Wrong assumption that peak time is only 1 h produced savings 5 times larger. • ESKOM & government overlooked providing Information on the SWH to the householders. • No maintenance led to abandonment by many or water leaking increasing utility bills.

  18. Assessment of radioactive contaminations of the ground in Hanover-List with scales and methods of the German Federal Ordinance on Soil Protection and Contaminated Sites (BBodSchV). Pt. 1. Derivation of test thresholds

    International Nuclear Information System (INIS)

    Gellermann, Rainer; Guenther, Petra; Evers, Burkhard

    2010-01-01

    Background, aim, and scope: In the district List of Hanover (Lower Saxony) radioactive contaminations of the ground were detected at a site of a former chemical plant. Due to the lack of an ordinance regarding intervention regulations in the case of radioactive contaminations in Germany this situation had to be assessed on the basis of scales and methods of the German regulations concerning soil protection and contaminated sites. In particular it was necessary to develop methods and levels for the assessment of radioactive contaminations. Materials and methods: Because radioactivity can be considered as a carcinogenic substance the methodical approaches of the BBodSchV for this group of substances were used in order to derive test thresholds for radioactive contaminations at children's play areas, residential areas as well as parks and recreation facilities. Results: For the assessment of radioactive soil contaminations with naturally occurring radionuclides at children's play areas and residential areas the ingestion of soil is the decisive pathway of exposure. For children's play areas a threshold level of 0.2 Bq/g for the sum U-238,max + Th-232,max was obtained. At areas with only impacts of ambient radiation from the contaminated ground test thresholds of 0.5 μSv/h are recommended. A special pathway is the migration of radon from the contaminated soil into basement floors of buildings. Taking into account the natural background levels of radon a concentration of 260 Bq/m 3 is suggested as a test threshold in the framework of soil protection benchmarks. Discussion and conclusions will be described in Part 2 of the paper.

    China introduced a series of health reforms in 2009, including a national essential medicines policy and a medical insurance system for primary care institutions. This study aimed to determine the changing prescribing patterns associated with those reforms in township hospitals. A multi-stage stratified random cluster sampling method was adopted to identify 29 township hospitals from six counties in three provinces. A total of 2899 prescriptions were collected from the participating township hospitals using a systematic random sampling strategy. Seven prescribing indicators were calculated and compared between 2008 and 2013, assessing use of medicines (antibiotics and adrenal corticosteroids) and polypharmacy, administration route of medicines (injections), and affordability of medicines. Significant changes in prescribing patterns were found. The average number of medicines and costs per-prescription dropped by about 50%. The percentage of prescriptions requiring antibiotics declined from 54% to 38%. The percentage of prescriptions requiring adrenal corticosteroid declined from 14% to 4%. The percentage of prescriptions requiring injections declined from 54% to 25%. Despite similar changing patterns, significant regional differences were observed. Significant changes in prescribing patterns are evident in township hospitals in China. Overprescription of antibiotics, injections and adrenal corticosteroids has been reduced. However, salient regional disparities still exist. Further studies are needed to determine potential shifts in the risk of the inappropriate use of medicines from primary care settings to metropolitan hospitals.

    Full Text Available The paper results from a research project completed by the author in 1994 on the quality of language-learning environments in the Cape Town area . . Xhosa is now constitutionally enshrined as one of the eleven official languages of South Africa, and is the dominant language in Western Cape black townships. This paper questions the fruitfUlness of primary schools in black townships attempting to use English as the sole medium of instruction. The paper shows that in actual classroom situations the Ll (Xhosa is used as an aid to L2 (English medium instruction in the schools of Khayelitsha and Lagunya townships around Cape Town. The paper argues for the recognition and forther extension of such bilingual practices in primary schools to work towards more successfUl use of the L2 as the medium of instruction.

    Research on the impact of stigma associated with mental illness in children is scarce. Considering the known negative effects of stigma associated with mental illness in adults, it is crucial to explore the stigma experienced by children who access mental health treatment. However, no scale measuring self-stigmatization in younger children is available to date. This study aimed to develop and validate such a scale, the Paediatric Self-Stigmatization Scale (PaedS). A total of 156 children (119 receiving outpatient and 37 receiving inpatient treatment), aged 8-12 years, completed the PaedS, the Self-Perception Profile for Children and the Pediatric Quality of Life Inventory (PedsQL - Child Report, ages 8-12). In addition, parents completed the PedsQL (Parent Report for Children, ages 8-12), the Strengths and Difficulties Questionnaire (SDQ) and a modified subscale of the PaedS measuring the children's rejection by others due to their mental health difficulties. A confirmatory factor analysis showed that a four-factor structure, comprising Societal Devaluation, Personal Rejection, Self-Stigma and Secrecy scales, had excellent fit to the data (CFI=0.95; TLI=0.95; RMSEA=0.05). Child-reported PaedS scores were positively correlated with parental-reported PaedS scores and negatively with PedsQL, the SDQ, and 5 out of 6 subscales of the Self-Perception Profile for Children, suggesting adequate convergent validity (all P-values<0.05). The PaedS is a valid instrument, which is hoped to advance the understanding of self-stigmatization in children with mental health difficulties and contribute to its prevention.

    Full Text Available Diabetic nephropathy (DN and diabetic retinopathy (DR are major complications of type 1 and type 2 diabetes. DN and DR are mainly caused by injury to the perivascular supporting cells, the mesangial cells within the glomerulus, and the pericytes in the retina. The genes and molecular mechanisms predisposing retinal and glomerular pericytes to diabetic injury are poorly characterized. In this study, the genetic deletion of proteasome activator genes, PA28α and PA28β genes, protected the diabetic mice in the experimental STZ-induced diabetes model against renal injury and retinal microvascular injury and prolonged their survival compared with wild type STZ diabetic mice. The improved wellbeing and reduced renal damage was associated with diminished expression of Osteopontin (OPN and Monocyte Chemoattractant Protein-1 (MCP-1 in the glomeruli of STZ-injected PA28α/PA28β double knockout (Pa28αβDKO mice and also in cultured mesangial cells and retinal pericytes isolated from Pa28αβDKO mice that were grown in high glucose. The mesangial PA28-mediated expression of OPN under high glucose conditions was suppressed by peptides capable of inhibiting the binding of PA28 to the 20S proteasome. Collectively, our findings demonstrate that diabetic hyperglycemia promotes PA28-mediated alteration of proteasome activity in vulnerable perivascular cells resulting in microvascular injury and development of DN and DR.

    Full Text Available Gallbladder (GB stones have been associated with several metabolic factors and liver diseases. This community-based study aimed at investigating the prevalence rate of GB stones and its associated factors in a hepatitis B virus (HBV/hepatitis C virus (HCV-endemic township in southern Taiwan. A total of 1701 residents (689 males and 1012 females; mean age: 51.2 ± 16.0 years were enrolled in this prospectively designed screening project. Serum biochemistry tests, including testing for levels of serum aspartate aminotransferase, alanine aminotransferase (ALT, hepatitis B surface antigen (HBsAg, and antibody to HCV (anti-HCV were conducted. In addition, a hepatobiliary ultrasonographic (US examination was also conducted. Of the 1701 residents, 243 (14.3% and 475 (27.9% were found to be positive for HBsAg and anti-HCV, respectively. Results of the US examination revealed the prevalence rate of GB stone and fatty liver to be 6.8% and 55.6%, respectively. Using univariate analyses we found that significantly higher proportions of the participants with GB stone were male, over 50 years of age, positive for anti-HCV (p = 0.001, p 50 year were identified as independent factors associated with the formation of GB stones. Anti-HCV was associated with GB stones in males but not in females in both univariate and multivariate analyses. GB stones were found to have a prevalence rate of 6.8% in this HCV/HBV hyperendemic township and are associated with higher mean age. A correlation between chronic hepatitis C and GB stones is observed only among males.

    Cash transfers (CTs) are increasingly used as a strategy to alleviate poverty and improve child health outcomes in low- and middle-income countries. The Child Support Grant (CSG) is the largest CT programme in South Africa, and on the continent, targeting poor children from birth until the age of 18 with a monthly sum of R300 (USD30). Evidence on the CSG shows that early receipt of the grant is associated with improved child health outcomes. Since its implementation, one of the major concerns about the grant has been take-up rates, particularly for younger children. This paper reports results on take-up rates for 12-week-old infants residing in an urban township in South Africa. This is a descriptive study utilising data from a community-based, cluster-randomised trial which evaluated a programme providing pregnancy and post-natal home visits by community health workers to 3,494 mothers in Umlazi township, South Africa. At the 12-week visit, half (52%) of the mothers who had enrolled in the study had applied for the CSG on behalf of their children, while 85% of the mothers who had not applied were still planning to apply. Only 38% (1,327) of all children had received the CSG. In this study, many mothers had not applied for the CSG in the first few months after delivery, and only a third of children had accessed the grant. Further research is needed to understand what the current barriers are that prevent mothers from applying for this important form of social protection in the early months after delivery.

    Full Text Available Proper planning and implementation of sound programs and strategies is vital to  agricultural development. Recognizing current problems and strengths of any section is required in the first step. One of the most important problems in the Iranian agriculture sector is land fragmentation. The purpose of this descriptive-correlational study was to investigate wheat farmers’ attitude and land consolidation solutions from their viewpoints in the Hashtrood Township in year 2013. A group of experts from different majors confirmed the validity of the questionnaire used as our research tool and by conducting a pilot test and the Cronbach’s alpha was calculated to be equal to 0.85 for attitude scale and 0.8 for solution scale, and hence its reliability was verified. The target population consisted of all of the wheat farmers in the Hashtrood Township in the East Azerbaijan province 186 of whom  were selected as samples from 15 villages based on Cochran’s sampling formula and the multi stage randomized sampling method. An analysis of the attitudes of wheat farmers revealed that 67.7 and 32.3 percent of them have unfavorable and neutral attitudes towards land consolidation. Also, there is a significant positive relationship between farming experience and their attitude in land consolidation, but there is a negative relationship between it and their total land segments.  Factor analysis of data revealed that four factors named as deterrent actions, cooperative-common actions, supportive-infrastructural actions and motivational extension actions explained 59.9% of land consolidation solutions by wheat farmers.

    Laboratory diagnosis of syphilis is usually accomplished by serology. There are currently a large number of different commercial treponemal tests available that vary in format, sensitivity and specificity. To evaluate the ID-PaGIA Syphilis Antibody Test as an alternative to other specific treponemal tests for primary screening or confirmation of diagnosis. Serum samples from healthy adults (n = 100) were used for detection of specificity of ID-PaGIA. To evaluate sensitivity of ID-PaGIA serum samples (n = 101) from patients with confirmed or suspected syphilis were tested for syphilis antibodies with FTA-Abs IgM, ID-PaGIA, ELISA IgM and TPHA tests. No false-positive results were found with ID-PaGIA. Sensitivity of various treponemal tests was the following: FTA-Abs IgM: 95.5%, ID-PaGIA and ELISA IgM: 94%, and TPHA 75%. The positive and negative predictive values of ID-PaGIA were 100 and 89.5%, respectively. Compared with other treponemal tests ID-PaGIA has excellent sensitivity and specificity.

    Tissue type plasminogen activator (tPA) induces neuronal apoptosis, disrupt the blood-brain-barrier (BBB), and promotes dilation of the cerebral vasculature. The timing, sequence and contributions of these and other deleterious effects of tPA and their contribution to post-ischemic brain damage after stroke, have not been fully elucidated. To dissociate the effects of tPA on BBB permeability, cerebral vasodilation and protease-dependent pathways, we developed several tPA mutants and PAI-1 derived peptides constructed by computerized homology modeling of tPA. Our data show that intravenous administration of human tPA to rats increases BBB permeability through a non-catalytic process, which is associated with reversible neurotoxicity, brain damage, edema, mortality and contributes significantly to its brief therapeutic window. Furthermore, our data show that inhibiting the effect of tPA on BBB function without affecting its catalytic activity, improves outcome and significantly extends its therapeutic window in mechanical as well as thromboembolic models of stroke.

    At present, the main test technique of AIDS is PA in China. Because the judgment of PA test image is still depending on operator, the error ration is high. To resolve this problem, we present a new technique of image processing, which first process many samples and get the data including coordinate of center and the rang of kinds images; then we can segment the image with the data; at last, the result is exported after data was judgment. This technique is simple and veracious; and it also turns out to be suitable for the processing and analyzing of other infectious diseases' PA test image

    Uranium, thorium and protactinium isotopes were measured in particulate matter collected by sediment traps deployed in the Panama Basin and by in-situ filtration of large volumes of seawater in the Panama and Guatemala Basins. Concentrations of dissolved Th and Pa isotopes were determined by extraction onto MnO 2 adsorbers placed in line behind the filters in the in-situ pumping systems. Concentrations of dissolved 230 Th and 231 Pa in the Panama and Guatemala Basins are lower than in the open ocean, whereas dissolved 230 Th/ 231 Pa ratios are equal to, or slightly greater than, ratios in the open ocean. Particulate 230 Th/ 231 Pa ratios in the sediment trap samples ranged from 4 to 8, in contrast to ratios of 30 or more at the open ocean sites previously studied. Particles collected by filtration in the Panama Basin and nearest to the continental margin in the Guatemala Basin contained 230 Th/ 231 Pa ratios similar to the ratios in the sediment trap samples. The ratios increased with distance away from the continent. Suspended particles near the margin show no preference for adsorption of Th or Pa and therefore must be chemically different from particles in the open ocean, which show a strong preference for adsorption of Th. Ocean margins, as typified by the Panama and Guatemala Basins, are preferential sinks for 231 Pa relative to 230 Th. Furthermore, the margins are sinks for 230 Th and, to a greater extent, 231 Pa transported by horizontal mixing from the open ocean. (orig.)

    There is a growing recognition internationally of the need to demonstrate comprehensiveness in order to build confidence in performance assessments (PAs) for radioactive waste disposal projects. This has resulted in a number of methodologies being developed to formalize the process of defining and documenting the decision basis that underlies a PA. Such methodologies include process influence diagrams and the rock engineering system (RES) matrix. However, these methodologies focus mainly on the conceptualization of the disposal system and do not provide a ready framework to document the decisions behind the model development and parameterization of the PA system. The Performance Assessment Support System (PASS) is a flexible electronic tool designed to increase the transparency and traceability of decision making in the entire PA process. An application of PASS has been developed for the Waste Isolation Pilot Plant (WIPP) where it forms an important component of Desk Top PA, a PC-based PA computational environment under development at Sandia National Laboratories to document, plan, and support management decisions and to assess performance for the WIPP recertification process. This desk-top PA environment is also aimed at providing scientifically-based decision support for assessing the performance of nuclear and hazardous waste management and environmental clean-up systems

    1998-01-01

    Purpose: To investigate the influence of hyperthermia up to 45 deg. C on fibrinolysis with recombinant tissue-type plasminogen activator (rt-PA). Methods: Standardized fibrin clots were incubated in a water bath for 5 hr with either rt-PA (test group) or 0.9% sodium chloride (control group) and blood plasma at temperatures of 30-45 deg. C. Concentrations of D-dimer and time to complete clot lysis were measured.Results: The activity of fibrinolysis with rt-PA rose with increasing temperature: time to lysis approximately halved from 30 deg. C to 40 deg. C and the concentration of D-dimer tripled. In the control group clot size did not change.Conclusions: Activity of rt-PA-induced fibrinolysis rises distinctly with higher temperatures. Since even healthy subjects show a physiologic decline in body temperature in the extremities, in patients with occlusive arterial disease decreased activity of fibrinolysis with rt-PA can be expected. Controlled hyperthermia may improve fibrinolysis with rt-PA and should be investigated in vivo

    To produce competent undergraduate-level medical doctors for rural township health centers (THCs), the Chinese government mandated that medical colleges in Central and Western China recruit rural-oriented, tuition-waived medical students (RTMSs) starting in 2010. This study aimed to identify and assess factors that influence the choice to work in rural township health centers among both RTMSs and other students from five medical universities in Guangxi, China. An internet-based self-administered questionnaire survey was conducted with medical students in Guangxi province. Multinomial logistic regression was used to identify factors related to the attitudes toward work in a rural township health center. Among 4,669 medical students, 1,523 (33%) had a positive attitude and 2,574 (55%) had a neutral attitude toward working in THCs. Demographic characteristics, personal job concerns, and knowledge of THCs were associated with the choice of a career in THCs. The factors related to a positive attitude included the following: three-year program, a rural-oriented medical program, being male, an expectation of working in a county or township, a focus on medical career development, some perceived difficulty of getting a job, having family support, sufficient knowledge of THCs, optimism toward THC development, seeking lower working pressure, and a lower expected monthly salary. Male students in a three-year program or a rural-oriented tuition-waived medical education program were more likely to work in THCs. Selecting medical students through interviews to identify their family support and intentions to work in THCs would increase recruitment and retention. Establishing favorable policies and financial incentives to improve living conditions and the social status of rural physicians is necessary.

Results: Among 4,669 medical students, 1,523 (33% had a positive attitude and 2,574 (55% had a neutral attitude toward working in THCs. Demographic characteristics, personal job concerns, and knowledge of THCs were associated with the choice of a career in THCs. The factors related to a positive attitude included the following: three-year program, a rural-oriented medical program, being male, an expectation of working in a county or township, a focus on medical career development, some perceived difficulty of getting a job, having family support, sufficient knowledge of THCs, optimism toward THC development, seeking lower working pressure, and a lower expected monthly salary. Conclusion: Male students in a three-year program or a rural-oriented tuition-waived medical education program were more likely to work in THCs. Selecting medical students through interviews to identify their family support and intentions to work in THCs would increase recruitment and retention. Establishing favorable policies and financial incentives to improve living conditions and the social status of rural physicians is necessary.

    PA4991 is a FAD-dependent oxidoreductase from the pathogen P. aeruginosa that is essential for virulence and survival in the infected host. The structure of this enzyme, determined to 2.4 Å resolution, reveals that PA4991 belongs to the GR{sub 2} family of flavoenzymes. The locus PA4991 in Pseudomonas aeruginosa encodes an open reading frame that has been identified as essential for the virulence and/or survival of this pathogenic organism in the infected host. Here, it is shown that this gene encodes a monomeric FAD-binding protein of molecular mass 42.2 kDa. The structure of PA4991 was determined by a combination of molecular replacement using a search model generated with Rosetta and phase improvement by a low-occupancy heavy-metal derivative. PA4991 belongs to the GR{sub 2} family of FAD-dependent oxidoreductases, comprising an FAD-binding domain typical of the glutathione reductase family and a second domain dominated by an eight-stranded mixed β-sheet. Most of the protein–FAD interactions are via the FAD-binding domain, but the isoalloxazine ring is located at the domain interface and interacts with residues from both domains. A comparison with the structurally related glycine oxidase and glycerol-3-phosphate dehydrogenase shows that in spite of very low amino-acid sequence identity (<18%) several active-site residues involved in substrate binding in these enzymes are conserved in PA4991. However, enzymatic assays show that PA4991 does not display amino-acid oxidase or glycerol-3-phosphate dehydrogenase activities, suggesting that it requires different substrates for activity.

    Successful designs to eliminate Mn from mine discharge are necessary for both restoring abandoned mine lands and permitting the mining of high sulfur coal in the eastern United States. A passive in-line system that meets Mn discharge limits was built at the discharge from the former Shade Township coal mine in south central Pennsylvania. Qualitative research on monthly changes in the microbial and algal community that removes Mn is underway. Epilithic attachment of microorganisms was analyzed on artificial (glass microscope slides) and natural substrates (limestone thin sections) that were immersed in surface water for one month periods over 6 months. Organisms attached to both glass and limestone substrates. Limestone became coated with 34--86% more Mn that did glass surfaces. Light microscopy revealed 12 different strategies are being used by bacteria, cyan bacteria, diatoms, green algae, and fungi to oxidize Mn. the dominant method used by the epilithic community to oxidize Mn is coating of holdfasts by the iron bacterium, Liptothrix discophora, and the green alga, Ulothrix sp. Other methods for Mn removal by oxidation include coating of individual cells, filaments/sheaths/hyphae, extracellular polysaccharides, and biofilms. The unplanned community at the site is multifaceted and extremely efficient in its Mn removal ability. Community interactions or complexity may play roles in the stability of the ecosystem and the efficiency of its Mn oxidizing ability

    Interpersonal violence is a major contributor to the burden of disease globally, and in South Africa, it is the leading cause of injury. There is an emerging consensus that the development of actionable policy and effective prevention strategies for interpersonal violence requires an understanding of the contextual matters that elevate risk for interpersonal violence. The objective of this study was to explore community perceptions of risks for interpersonal violence in five townships in Cape Town, South Africa, with high rates of violence. Focus group discussions were conducted with community members to identify key factors in that contributed to being either a perpetrator or victim of interpersonal violence. The ecological framework was used to classify the risk factors as occurring at individual, relationship, community or society levels. Some of the risk factors identified included alcohol abuse, poverty, informality of settlements and cultural norms. Differences in how each of these risk factors are expressed and experienced in the five communities are also elucidated. This approach enabled the collection of contextual community-based data that can complement conventional surveillance data in the development of relevant community-level strategies for interpersonal violence prevention.

    This paper presents important management guidelines for conducting a tourism planning process in the township of San Francisco de Asis, which were developed from the conceptual notion of sustainable tourism and participation of local people. This case considered the participatory research method, used ethnography techniques and implemented shops with the community. As a main result proposed the consolidation of four components, socio- political, socio- cultural, social- ecological and socio- economic; that must be managed in an integrated fashion to achieve real sustainable tourism in this territory. In the first component outlines an participatory process that must take place between the various stake holders; in the second considered strengthen the social tissue and valuing cultural traditions to adequately integrate tourism activities; the third proposes an integrated environmental conservation in the whole territory and as an obligation of all stake holders, including to tourists; finally, in the fourth component, recommend the creation of more opportunities and general welfare for the entire local population in order to prevent the growth of tourism segregated. As a general conclusion will projected that the implementation of these guidelines permitted advance, from the practical, in the development of a truly sustainable tourism that help improve the living conditions of local people and conserve valuable natural and cultural resources that exist in this territory.

    Surveys and discussions were given on establishing a new energy vision in Yatsuka Township in Shimane Prefecture. For the survey on available amount of natural energies (sunlight and wind), all-weather insolation required for solar energy power generation was analyzed by using the NEDO information, and wind was analyzed based on observations at Matsue Meteorological Observatory, Sakai-minato Observatory, and Nakaura Water Gate. In discussing the system, power generation amount in the Matsue area was estimated for the case when solar cells of single crystal silicon plus amorphous hybrid type HIP-H48B1 are used. For wind power generation, power generation amount was calculated from observation values derived at the Nakaura water gate when wind mills with diameters from 2 to 10 m are used. Furthermore, calculations were performed on power amount generated uniformly by using a hybrid system using solar energy power generation and wind power generation. As a result of the discussions, a plan was established to introduce the new energies by means of a solar and wind energy hybrid power generation system to the greenhouse 'Green Stellar' symbolizing the Japan's largest peony production, being capable of year-round peony cultivation. The system is planned to be introduced to the town office building and other public organizations sequentially according to annual programs. (NEDO)

  13. An investigation into the disciplinary methods used by teachers in a secondary township school in South Africa

    Full Text Available The research that this article reports on investigated the incidence of learner discipline problems, the effect of them on teachers, the teachers’ methods of maintaining discipline and the effectiveness of those methods in one township, namely Jouberton in Klerksdorp, South Africa. The experiences of both teachers and learners were surveyed. It was found that discipline at the school is far from satisfactory and problems with discipline are more serious than the international norm indicates. These problems have a serious effect on a large part of the teachers’ family life, personal health, job satisfaction and morale. Whilst both teachers and learners commendably prefer the educationally sound preventive and positive methods of maintaining discipline, the application of these methods appears not to be effective: it seems as if teacher education falls short in the area of maintaining discipline, particularly regarding the successful application of proactive methods of maintaining discipline. Finally, the learners’ views on the maintenance of discipline are an alarming indictment of the principles of democracy, human rights and human dignity, and of rationality as a tool for conflict resolution. Recommendations are made for follow-up research with the objective of amelioration.

    Job satisfaction is important to staff management of township health centers (THCs), as it is associated with organizational performance, quality of care and employee retention. The purpose of this study was to measure job satisfaction level of THC employees in poor rural China and to identify relevant features in order to provide policy advice on human resource development of health service institutions in poor regions. A self-completion questionnaire was used to assess the job satisfaction and relevant features (response rate: 90.5%) among 172 employees (i.e., clinic doctors, medico-technical workers and public health workers) of 17 THCs in Anhui and Xinjiang provinces of China. The study covered a time period of two months in 2007. The mean staff job satisfaction scored 83.3, which was in the category of "somewhat satisfied" on a scale ranging from 0 (extremely dissatisfied) to 100 (extremely satisfied) by employing Likert's transformation formula. Exploratory factor analysis (EFA) revealed eight domains involved in modeling of job satisfaction, among which, the caregivers were more satisfied with job significance (88.2), job competency (87.9) and teamwork (87.7), as compared with work reward (72.9) and working conditions (79.7). Mean job satisfaction in Xinjiang (89.7) was higher than that in Anhui (75.5). Employees of THCs have moderate job satisfactions in poor areas, which need to be raised further by improving their working conditions and reward.

    To evaluate flood-prone areas, correlation analysis of flooding factors for the quantitative evaluation of hazard degree was determined to assist in further disaster prevention management. This study used flood-prone areas in 35 villages over eight townships (Changhua, Huatan, Yuanlin, Xiushui, Puyan, Hemei, Dacun, and Erlin) in Changhua County as research samples. Linear combination was used to evaluate flood-prone environmental indices, and an expert questionnaire was designed by using the analytic hierarchy process and the Delphi method to determine the weights of factors. These factors were then used to calculate the eigenvector of a pairwise comparison matrix to obtain the weights for the risk assessment criteria. Through collection of disaster cases, with particular focus on specifically protected areas where flooding has occurred or is likely to occur, public adaptation and response capabilities were evaluated by using an interview questionnaire that contains the items of perceived disaster risk, resource acquisition capability, adaptation capability, and environment understanding and disaster prevention education. Overlays in a geographic information system were used to analyze the flood-risk degree in villages and to construct a distribution map that contains flood-prone environment indices. The results can assist local governments in understanding the risk degree of various administrative areas to aid them in developing effective mitigation plans.

    Scheepers, Ruth

    2008-12-01

    Full Text Available This paper discusses the development of the vocabulary of grade 7 learners in a reading project currently underway at a school in Atteridgeville, a township on the outskirts of Pretoria. A library has been established at the school and teachers throughout the school attend workshops designed to heighten their awareness of the value of reading and the importance of vocabulary, and to provide them with strategies to facilitate the development of reading. This paper focuses on the vocabulary development of grade 7 learners – they are in the senior phase of primary school and will soon be entering high school where they will be faced with more academic vocabulary in context-reduced textbooks. Learners’ vocabulary was tested early in the year and then again towards the end to assess whether increased access to books and reading had had an effect on vocabulary growth. Results revealed that learners at the project school showed a lack of vocabulary, even at the end of the study period, not only in terms of academic words but also high frequency words. Extensive reading alone is clearly not enough – learners need explicit vocabulary instruction: in order to read successfully at high school level, learners need a working knowledge of academic vocabulary, and this knowledge is developed by reading – but learners cannot read successfully without an adequate basic high-frequency vocabulary.

    Full Text Available Background: Community health workers (CHWs are increasingly being recognised as a crucial part of the health workforce in South Africa and other parts of the world. CHWs have taken on a variety of roles, including community empowerment, provision of services and linking communities with health facilities. Their roles are better understood in the areas of maternal and child health and infectious diseases (HIV infection, malaria and tuberculosis. Aim: This study seeks to explore the current roles of CHWs working with non-communicable diseases (NCDs. Setting: The study was conducted in an urban township in Cape Town, South Africa. Method: A qualitative naturalistic research design utilising observations and in-depth interviews with CHWs and their supervisors working in Khayelitsha was used. Results: CHWs have multiple roles in the care of NCDs. They act as health educators, advisors, rehabilitation workers and support group facilitators. They further screen for complications of illness and assist community members to navigate the health system. These roles are shaped both by expectations of the health system and in response to community needs. Conclusion: This study indicates the complexities of the roles of CHWs working with NCDs. Understanding the actual roles of CHWs provides insights into not only the competencies required to enable them to fulfil their daily functions, but also the type of training required to fill the present gaps.

    Full Text Available A clear preference for English as language of teaching and learning (LoLT is evident in most South African schools. However, discrepancies exist between language policy aims and educational outcomes with regard to the successful acquisition of English among English second language (ESL learners. Effective participation in all learning activities is closely linked to learners’ proficiency in the LoLT; poor English proficiency leads to underachievement across the curriculum. In the light of this, a case study as conducted to investigate the English reading and writing performance of Grade 7 Xitsonga-speaking learners in three selected township schools in the Tshwane metropolitan area, Gauteng Province. Firstly, a literature review was undertaken to explore the importance of reading and writing skills in the classroom with particular reference to the demands made on ESL learners. Following this, standardised tests were used to assess the learners’ English reading and writing performance. Findings indicated that learners performed poorly in both reading and writing; however, no significant relationship could be demonstrated between reading and writing, possibly due to the nature of the components of the test. The overall lack of reading and writing competence in English holds implications for learners’ academic achievement in all learning areas in situations in which English is used as the LoLT.

    Unlike large firms with management teams, small businesses are usually run by one key person, the owner-entrepreneur, who bears almost all of the risks and makes almost all of the decisions related to the business. Because the owner-entrepreneur also embodies most of the firm-specific knowledge capital, health of the owner-entrepreneur is an important factor in the production process. Following a cohort of respondents in townships around Durban, South Africa, over a three-year period, we examined the relationship between an individual’s physical health and the decision to start a business. Our results suggest that respondents who were recent business entrants were in better health than respondents who did not start new businesses. Moreover, respondents without a business at the beginning of the study who later opened businesses during the three-year study interval were significantly more likely to have better baseline health than those respondents who never started a new business. Hence, good health among entrepreneurs seems to be an important prerequisite to small business entry. PMID:21603114

    In various organisms, thioredoxins are known to be involved in the reduction of protein disulfide bonds and in protecting the cell from oxidative stress. Genes encoding thioredoxins were found by searching the complete genome sequence of the filamentous ascomycete Podospora anserina. Among them, PaTrx1, PaTrx2, and PaTrx3 are predicted to be canonical cytosolic proteins without additional domains. Targeted disruption of PaTrx1, PaTrx2, and PaTrx3 shows that PaTrx1 is the major thioredoxin inv...

    Radiation dose to the testes in the antero-posterior (AP) and postero-anterior (PA) projection of the sacroiliac joint (SIJ) was measured with and without a scrotal shield. Entrance surface dose, the dose received by the testicles and the dose area product (DAP) was used. DAP measurements revealed the dose received by the phantom in the PA position is 12.6% lower than the AP (p {<=} 0.009) with no statistically significant reduction in image quality (p {<=} 0.483). The dose received by the testes in the PA projection in SIJ imaging is 93.1% lower than the AP projection when not using protection (p {<=} 0.020) and 94.9% lower with protection (p {<=} 0.019). The dose received by the testicles was not changed by the use of a scrotal shield in the AP position (p {<=} 0.559); but was lowered by its use in the PA (p {<=} 0.058). Use of the PA projection in SIJ imaging significantly lowers, the dose received by the testes compared to the AP projection without significant loss of image quality.

    Recent studies show that compounding polyamide 6 (PA 6) with a PA 6 polyether block copolymers made by reaction injection molding (RIM) or continuous anionic polymerization in a reactive extrusion process (REX) result in blends with high impact strength and high stiffness compared to conventional rubber blends. In this paper, different high impact PA 6 blends were prepared using a twin screw extruder. The different impact modifiers were an ethylene propylene copolymer, a PA PA 6 polyether block copolymer made by reaction injection molding and one made by reactive extrusion. To ensure good particle matrix bonding, the ethylene propylene copolymer was grafted with maleic anhydride (EPR-g-MA). Due to the molecular structure of the two block copolymers, a coupling agent was not necessary. The block copolymers are semi-crystalline and partially cross-linked in contrast to commonly used amorphous rubbers which are usually uncured. The combination of different analysis methods like atomic force microscopy (AFM), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) gave a detailed view in the structure of the blends. Due to the partial cross-linking, the particles of the block copolymers in the blends are not spherical like the ones of ethylene propylene copolymer. The differences in molecular structure, miscibility and grafting of the impact modifiers result in different mechanical properties and different blend morphologies.

    Full Text Available This paper is intended to be a comprehensive analysis of the evidence of ku-pa-ro in the Knossos Linear B tablets. Its main purpose is to set up the importance of such aromatic plant in the Mycenaean economy at Knossos and to identify what kind of sedge was concealed under the name ku-pa-ro and what part of the plant was used and for what purposes. What it is stressed is the usage of the Cyperus rotundus L. (i. e. the ku-pa-ro in the industry of perfumes and as a food additive as well. What is inferred from the discussion on the evidence of ku-pa-ro issues a series of valuable data concerning the localization of certain place-names in the map of Crete, and concerning the explanation of ideogram *171. The high qualities of ku-pa-ro preserved in the tablets lead the author to assume that such a plant was cultivated in Crete and was one of the main aromatic plants used by the Mycenaeans in the making of perfumes.

  7. Pa2 kinematic bond in translational parallel manipulators

    2018-01-01

    Full Text Available The Pa2 pair is composed of two intertwined articulated parallelograms connecting in parallel two links of a kinematic chain. This pair has two translational degrees of freedom leading to a translational plane variable with the position. Currently, the Pa2 pair appears in conceptual designs presented in recent papers. However, its practical application is very limited. One of the reasons for this can be the high number of redundant constraints it has. But, it has to be considered that most of them can be eliminated by replacing wisely the revolute joints by spherical joints. On the other side, the structure of the Pa2 pair contributes to increase the global stiffness of the kinematic chain in which it is mounted. Also, its implementation is a promising alternative to the problematic passive prismatic joints. In this paper, the Pa2 pairs are used in the design of a 3 − P Pa2 parallel manipulator. The potentiality of this design is evaluated and proven after doing the following analyses: direct and inverse kinematics, singularity study, and workspace computation and assessment.

    The purpose of this study is to conduct a cross-cultural adaptation of the Assistive Technology Device Predisposition Assessment (ATD PA) for use in Brazil. The selection of the Assistive Technology Device Predisposition Assessment (ATD PA) was determined by previous literature reviews of articles published in 2014 and 2016 in six databases with the terms "assistive device" or "assistive technology" or "self-help device" combined with "evidence-based practice" or "framework" or "measurement scale" or "model and outcome assessment". This review indicated that the conceptual model of Assistive Technology (AT) most discussed in the literature was the Matching Person and Technology (MPT) model, and this finding determined the selection of ATD PA as an assessment within the MPT portfolio of measures. The procedures for cross-cultural adaptation were as follows: Equivalence of Concept, Semantic and Operational. Five experts were asked to translate 725 items and these translations were evaluated and a high level of agreement was demonstrated. The Portuguese version, Avaliação de Tecnologia Assistiva - Predisposição ao Uso - ATD PA Br, was derived from the original version in English (ATD PA). The ATD PA Br will support professionals and people with disabilities in Brazil to better select AT devices according to the clients' needs.

    The nematode Caenorhabditis elegans is a simple model host for studying the interaction between bacterial pathogens such as Pseudomonas aeruginosa and the metazoan innate immune system. Powerful genetic and molecular tools in both C. elegans and P. aeruginosa facilitate the identification and analysis of bacterial virulence factors as well as host defense factors. Here we describe three different assays that use the C. elegans-P. aeruginosa strain PA14 host-pathogen system. Fast Killing is a toxin-mediated death that depends on a diffusible toxin produced by PA14 but not on live bacteria. Slow Killing is due to an active infection in which bacteria colonize the C. elegans intestinal lumen. Liquid Killing is designed for high-throughput screening of chemical libraries for anti-infective compounds. Each assay has unique features and, interestingly, the PA14 virulence factors involved in killing are different in each assay.

    Background: Township cadres, considered as basic executors of state policy, play an important role in Chinese society. Their job satisfaction is a vital issue for township management, but there are few studies on this topic in China. The goal of this study is to analyze the relationship between occupational stress and job satisfaction, and to further examine whether psychological capital (PsyCap) can serve as a mediator between stress and job satisfaction in Chinese township cadres. Methods: A cross-sectional survey was carried out during the period of from October 2015 to January 2016 in Liaoning Province of China. The questionnaires, which consisted of an effort-reward imbalance scale, Minnesota Satisfaction Questionnaire (MSQ) for job satisfaction, and the psychological capital questionnaire (PCQ-24), as well as questions about demographic characteristics, were distributed to 1800 township cadres and complete responses were received from 1525 participants. Structural equation modeling was used to examine the role that psychological capital played in mediating between occupational stress and job satisfaction. Results: In the present study, effort-reward ratio (ERR= 11 × effort/6 × reward) was negatively associated with job satisfaction (r = −0.372, p job satisfaction in township cadres (r = 0.587, p job stress and job satisfaction. Conclusions: Psychological capital partially mediated the relationship between job stress and job satisfaction among Chinese township cadres. Interventions to improve Chinese township cadres’ job satisfaction should be developed in the future, especially the enhancement of PsyCap. Interventions need to be verified in further cohort studies. At present, we are only proposing a theoretical model. Intervention effects need to be validated in further cohort studies. PMID:28846644

    In various organisms, thioredoxins are known to be involved in the reduction of protein disulfide bonds and in protecting the cell from oxidative stress. Genes encoding thioredoxins were found by searching the complete genome sequence of the filamentous ascomycete Podospora anserina. Among them, PaTrx1, PaTrx2, and PaTrx3 are predicted to be canonical cytosolic proteins without additional domains. Targeted disruption of PaTrx1, PaTrx2, and PaTrx3 shows that PaTrx1 is the major thioredoxin involved in sulfur metabolism. Deletions have no effect on peroxide resistance; however, data show that either PaTrx1 or PaTrx3 is necessary for sexual reproduction and for the development of the crippled growth cell degeneration (CG), processes that also required the PaMpk1 mitogen-activated protein kinase (MAPK) pathway. Since PaTrx1 PaTrx3 mutants show not an enhancement but rather an impairment in CG, it seems unlikely that PaTrx1 and PaTrx3 thioredoxins participate in the inhibition of this MAPK pathway. Altogether, these results underscore a role for thioredoxins in fungal development. PMID:17933907

    Full Text Available Background: Globally, there is evidence that three micronutrients deficiencies are of public health concern among children. They are vitamin A, iodine and iron deficiencies. Communities particularly affected are those in situations where poverty, unemployment, civil unrest, war and exploitation remain endemic. Malnutrition is an impediment to productivity, economic growth and poverty eradication. It is estimated that 32% of the global burden would be removed by eliminating malnutrition, including micronutrients deficiencies. Setting: The study was carried out in NkowaNkowa township of Mopani District, Limpopo Province, South Africa. Aim: The main objective was to determine the women’s knowledge on food fortification. Methods: The study design was descriptive. The snowballing method was used to identify women of child-bearing age. Data were collected from 120 participants using a questionnaire. The questionnaire consisted of socio-demographic, general questions on women’s knowledge on food fortification. The questionnaire was administered by the researcher using the local language Xitsonga. Results: The findings of the study revealed that a majority of 204 (57.0% of the participants were able to define food fortification correctly while 257 (72.0% of the participants knew which foods are fortified as well as the benefits of a food fortification programme. The majority (252 [70.0%] of the participants knew that maize meal is one of the food vehicle used for fortification in South Africa. Conclusion: Most of the questions were answered correctly by more than 50.0% of the participants. The researcher deduced that the study participants are knowledgeable about food fortification based on the response given in relation to the programme.

    Full Text Available Introduction and Context: Stigma associated with psychiatric disorders and few somatic disorders such as sexually transmitted diseases (STDs, tuberculosis and leprosy, adversely effects treatment seeking behavior, leads to concealment, and poor compliance with treatment. In busy outpatient departments (OPDs, the issue of stigma is likely to be overlooked. Materials and Methods: We carried out a cross-sectional study collecting data on an 8-item stigma scale from patients attending psychiatry and other OPDs of a Tertiary Care Teaching Hospital in an industrial township. Information was collected by face to face interview from 400 patients attending psychiatry OPD and 401 patients attending other OPDs. Validations of the scale were done by face, content, and construct validity. Reliability was appraised by Cronbach′s alpha and Guttmann split-half coefficients. Significant differences in answers to the 8-item questionnaire were explored by Chi-square test for individual responses and Kruskal-Wallis test for difference in total stigma score. Results: Patients attending psychiatry OPD consistently gave responses indicating a greater degree of perceived stigma than those attending OPD for somatic disorders. This difference was almost 3-4 times more on most of the items (P < 0.001. Among somatic disorders, stigma was highest (even higher than psychiatric disorders among STDs, tuberculosis and leprosy patients among these and psychiatric disorders the score was almost 3 times more compared to other somatic disorders (P < 0.001. The scale demonstrated good face, content, and construct validity. Reliability was also very high with Cronbach′s alpha coefficient and Guttmann split-half reliability coefficient 0.932 and 0.901 indicating very good internal consistency of the 8-item scale. Conclusion: Stigma was higher among STD patients, tuberculosis, leprosy, and psychiatry patients as compared to patients suffering from somatic disorders. Assessment of

    The electronic structure of the endohedral complex Pa at sign C 28 was studied using ab initio quantum chemical methods including relativistic core potentials, gaussian double zeta basis sets, and spin-orbit configuration interaction calculations. As in U at sign C 28 , the self consistent field population analysis shows extensive mixing of Pa 6d and 5f orbitals with C π orbitals, indicating strong binding. The energy of the C 28 cage π* orbitals (e symmetry) is lower than that of the Pa 5f orbitals. The ground state has an e 1 configuration at both the SCF and CI level calculations. The lowest f 1 state is 1.68 eV and 1.70 eV above the ground state from SCF and CI calculations respectively. Previous calculations on U at sign C 28 showed that the ground state of U at sign C 28 is a π*f state instead of an f 2 state. The results for Pa at sign C 28 support that finding

    Full Text Available Introduction: Oil seeds are the second world’s food supply after cereals. These crops are grown primarily for the oil contained in the seeds. The major world sources of edible seed oils are soybeans, sunflowers, canola, cotton and peanuts. Canola is one of the most important plants in the world that has great importance. The plant belongs to the Brassica genus, the botanical family that includes cauliflower and cabbages. Weeds are one of the major problems in canola production that reduce yield and its quality. In general, one of the most important factors in development of management plans is information about the weed’s flora and geographic distribution. Knowledge of weed flora enables one to use the required herbicide and formulate other suitable management strategies. It is also useful in exploiting abundant weeds as a cover crop or pasture and for other economic uses. The geographic information system has the proper use in weed science and management of agricultural information and their analysis. In this study, distribution and flora of the weeds in canola fields of Gorgan Township investigated by Geographic Information System. Material and Methods: Crop sampling was conducted during May and June 2014, in 58 canola fields in Gorgan Township (Golestan province and the weed species were sampled and detected using a W method and by specific formula of density, frequency, uniformity, and abundance of each weed species was calculated. Also, geographic coordinates of fields (latitude, altitude and elevation were determined by using GPS model Garmin map 60. After collecting data, in order to create a database of weed distribution, the data was transferred from GPS to ArcGIS 9/3.1 software. From all information obtained, consistently a database with location was created and after separation of data based on present or absence of weeds on fields, distribution maps were produced. Results and Discussion: The results showed that there are 35 weed

    Full Text Available BACKGROUND: The human immunodeficiency virus (HIV and hepatitis C virus (HCV are major public health problems. Many studies have been performed to investigate the association between demographic and behavioral factors and HIV or HCV infection. However, some of the results of these studies have been in conflict. METHODOLOGY/PRINCIPAL FINDINGS: The data of all entrants in the 11 national methadone clinics in the Yi Autonomous Prefecture from March 2004 to December 2012 were collected from the national database. Several spatial regression models were used to analyze specific community characteristics associated with the prevalence of HIV and HCV infection at the township level. The study enrolled 6,417 adult patients. The prevalence of HIV infection, HCV infection and co-infection was 25.4%, 30.9%, and 11.0%, respectively. Prevalence exhibited stark geographical variations in the area studied. The four regression models showed Yi ethnicity to be associated with both the prevalence of HIV and of HIV/HCV co-infection. The male drug users in some northwestern counties had greater odds of being infected with HIV than female drug users, but the opposite was observed in some eastern counties. The 'being in drug rehabilitation variable was found to be positively associated with prevalence of HCV infection in some southern townships, however, it was found to be negatively associated with it in some northern townships. CONCLUSIONS/SIGNIFICANCE: The spatial modeling creates better representations of data such that public health interventions must focus on areas with high frequency of HIV/HCV to prevent further transmission of both HIV and HCV.

    2008-01-01

    The crystal structure of an acetyltransferase encoded by the gene PA1377 from Pseudomonas aeruginosa has been determined at 2.25 Å resolution. Comparison with a related acetyltransferase revealed a structural difference in the active site that was taken to reflect a difference in substrate binding and/or specificity between the two enzymes. Gene PA1377 from Pseudomonas aeruginosa encodes a 177-amino-acid conserved hypothetical protein of unknown function. The structure of this protein (termed pitax) has been solved in space group I222 to 2.25 Å resolution. Pitax belongs to the GCN5-related N-acetyltransferase family and contains all four sequence motifs conserved among family members. The β-strand structure in one of these motifs (motif A) is disrupted, which is believed to affect binding of the substrate that accepts the acetyl group from acetyl-CoA

    The current status of coherent energy loss is reviewed, both in theory and in its phenomenological applications to p-A collisions. The induced energy loss is not bounded in general, but only in the specific situation where the energetic parton is suddenly accelerated (as in deep inelastic scattering) in the nuclear medium. In the situation where the parton is asymptotic, i.e. 'prepared' at t = -∞ and 'tagged' at t = +∞ after crossing a nuclear medium of thickness L (a situation relevant to forward hadron production in p-A collisions), ΔE appears to be proportional to E. Both situations are detailed in the article

    The application of 230 Th and 231 Pa growth methods to the hard tissues of living things, which are effective for the radiometric age measurement for latter Quaternary period, has been limited to certain corals, therefore it has been scarcely utilized in other areas than coral reefs. Reef coral fossils (Porites) were obtained from terrace deposits of Magdalena Island in Southern Baja California, and the methods were applied to them. At the time, the isotope compositions of Th, Pa and U in the shells of echinoderm Encope Grandis and of the living samples were examined. The estimated ages were in agreement with those of coral. It suggests that the reliable 230 Th and 231 Pa ages of sea-urchin fossils were presented for the first time and that the method is applicable to such fossils only if the conditions can be met. The results are highly significant, since the method may be used in other areas than coral reefs. (J.P.N.)

    Japan's nuclear development is carried out in the spirit of the Atomic Energy Basic Law that it adopted in 1955. The only nation in the world devastated by nuclear weapons, Japan strongly hopes for the abolishment of nuclear weapons and promotes the peaceful use of nuclear energy. Since Japan is in poor in natural resources nuclear power has now become a major foundation of our society and economy. As far as the Japanese people's awareness of nuclear power generation is concerned, 60% recognize it as necessary although 70% are concerned about its safety. The public acceptance (PA) of nuclear energy is facing a critical juncture at thus point due to such imminent issues as the use of plutonium and the disposal of high-level wastes. The entire Japanese government is currently striving to promote PA measures targeting various population groups. This paper reports on the peaceful use of nuclear energy and Japan's stance on this issue; people's awareness; and the current state of nuclear energy PA measures. 1 fig

    Four proteins from NCBI cog1816, previously annotated as adenosine deaminases, have been subjected to structural and functional characterization. Pa0148 (Pseudomonas aeruginosa PAO1), AAur1117 (Arthrobacter aurescens TC1), Sgx9403e, and Sgx9403g have been purified and their substrate profiles determined. Adenosine is not a substrate for any of these enzymes. All of these proteins will deaminate adenine to produce hypoxanthine with k{sub cat}/K{sub m} values that exceed 10{sup 5} M{sup -1} s{sup -1}. These enzymes will also accept 6-chloropurine, 6-methoxypurine, N-6-methyladenine, and 2,6-diaminopurine as alternate substrates. X-ray structures of Pa0148 and AAur1117 have been determined and reveal nearly identical distorted ({beta}/{alpha}){sub 8} barrels with a single zinc ion that is characteristic of members of the amidohydrolase superfamily. Structures of Pa0148 with adenine, 6-chloropurine, and hypoxanthine were also determined, thereby permitting identification of the residues responsible for coordinating the substrate and product.

    2006-01-01

    In 2004, a public-health nuisance was declared by the Wayne County Board of Health in the Scenic Heights Drive-Batdorf Road area of Wooster Township, Wayne County, Ohio, because of concerns about the safety of water from local wells. Repeated sampling had detected the presence of fecal-indicator bacteria and elevated nitrate concentrations. In June 2006, the U.S. Geological Survey (USGS), in cooperation with the Ohio Environmental Protection Agency (Ohio EPA), collected and analyzed samples from some of the affected wells to help investigate the possibility of human-origin bacterial contamination. Water samples from 12 wells and 5 home sewage-treatment systems (HSTS) were collected. Bromide concentrations were determined in samples from the 12 wells. Samples from 5 of the 12 wells were analyzed for wastewater compounds. Total coliform, enterococci and Escherichia coli (E. coli) bacteria concentrations were determined for samples from 8 of the 12 wells. In addition, two microbial source-tracking tools that employ DNA markers were used on samples from several wells and a composite sample of water from five septic tanks. The DNA markers from the Enterococcus faecium species and the order Bacteroidales are associated with specific sources, either human or ruminant sources. Bromide concentrations ranged from 0.04 to 0.18 milligrams per liter (mg/L). No wastewater compounds were detected at concentrations above the reporting limits. Samples from the 12 wells also were collected by Ohio EPA and analyzed for chloride and nitrate. Chloride concentrations ranged from 12.6 to 61.6 mg/L and nitrate concentrations ranged from 2.34 to 11.9 mg/L (as N). Total coliforms and enterococci were detected in samples from 8 wells, at concentrations from 2 to 200 colony-forming units per 100 milliliters (CFU/100 mL) and 0.5 to 17 CFU/100 mL, respectively. E. coli were detected in samples from three of the eight wells, at concentrations of 1 or 2 CFU/100 mL. Tests for the human

  20. Impact of suburban residential development on water resources in the area of Winslow Township, Camden County, New Jersey

    1981-01-01

    Surface-water and ground-water quality, streamflow, and data on ground-water levels in the upper Great Egg Harbor River basin in the vicinity of the Winslow Crossing residential development in Winslow Township are evaluated. The data include continuous streamflow at four sites, monthly stream water quality at seven sites, ground-water levels and periodic ground-water quality in four wells from 1972 through 1978. Pumpage from the Cohansey Sand in the study area was lower than anticipated because of a slowdown in construction. The average pumpage of 0.48 million gallons per day during 1978 had little effect on ground-water levels. Dissolved-solids concentrations were lower in a well upgradient from the urbanized area. Elevated levels of dissolved solids, specific conductance, chloride, nitrate, and phosphorus were found in the shallow ground water in the vicinity of the Winslow wastewater treatment plant because of effluent infiltration ponds. Nitrate was greatly reduced in October 1974 by a change in the treatment process, which increased denitrification. Phosphorus concentrations in the ground water remained elevated, however. Water from the most urbanized drainage basin was a magnesium bicarbonate type, while the less developed basins had sodium chloride sulfate type waters. Water from the two developed basins had higher median pH (7.1) compared with that of the other basins (5.6-6.3). Winslow Crossing?s development had only a slight effect on the quality of water in Great Egg Harbor River. The river receives point and non-point discharges upstream from Winslow Crossing, and the quality of the water generally improves as the river flows downstream. Streamflow and rainfall were slightly above normal. Unit hydrograph analysis of one basin showed an 80 percent increase in the peak discharge of a 60-minute unit hydrograph (from approximately 150 to 270 cubic feet per second) after the development of 14 percent of the basin.

    The 38-acre Fischer and Porter Company Superfund Site is in Warminster Township, Bucks County, Pa. Historically, as part of the manufacturing process, trichloroethylene (TCE) degreasers were used for parts cleaning. In 1979, the Bucks County Health Department detected TCE and other volatile organic compounds (VOCs) in water from the Fischer and Porter on-site supply wells and nearby public-supply wells. The Fischer and Porter Site was designated as a Superfund Site and placed on the National Priorities List in September 1983. A 1984 Record of Decision for the site required the Fischer and Porter Company to pump and treat groundwater contaminated by VOCs from three on-site wells at a combined rate of 75 gallons per minute to contain groundwater contamination on the property. Additionally, the Record of Decision recognized the need for treatment of the water from two nearby privately owned supply wells operated by the Warminster Heights Home Ownership Association. In 2004, the Warminster Heights Home Ownership Association sold its water distribution system, and both wells were taken out of service. The report describes changes in groundwater levels and contaminant concentrations and migration caused by the shutdown of the Warminster Heights supply wells and presents a delineation of the off-site groundwater-contamination plume. The U.S. Geological Survey (USGS) conducted this study (2006-09) in cooperation with the U.S. Environmental Protection Agency (USEPA). The Fischer and Porter Site and surrounding area are underlain by sedimentary rocks of the Stockton Formation of Late Triassic age. The rocks are chiefly interbedded arkosic sandstone and siltstone. The Stockton aquifer system is comprised of a series of gently dipping lithologic units with different hydraulic properties. A three-dimensional lithostratigraphic model was developed for the site on the basis of rock cores and borehole geophysical logs. The model was simplified by combining individual lithologic

    Using electron paramagnetic resonance (EPR), we studied the tree radical formation in high-density Polyethylene (HDPE), polyamide (PA6) and HDPE/PA6 (80/20)blend, irradiated with integral doses (D), 0 < D < 1000 KGy, with a dose rate of irradiation in air of 6.6 KGy/h. Typical spectra indicative of the formation of allyl, alkyl and poly enyl radicals were obtained. A decay in the total number of spins per gram (C/g), when the samples are aged by a period of time of 30 days, was found, which is typical of a recombination of radicals with their environment. Additionally, a different order fit for the C/g as a function of D was obtained, which is indicative of the complex behavior of the kinetics of the decomposition. (Author)

    Discussions were given and establishment was made on the new energy vision at Yonaguni Township in Okinawa Prefecture. The overall image of the new energy introduction vision at Yonaguni Township may be depicted by the wind power generation project to be implemented by the Development Public Corporation, by which megawatt-class wind power generation facilities will be built for effective utilization of the power by the whole island. Surplus electric power generated in a great amount in a certain season will be utilized for high value addition by electrifying agricultural works, expansion in production, (water pumping-up for irrigation, prawn cultivation, and sugar making factories), and melting and volume reducing of refuses. In addition, new type batteries for power storage with large capacity will be introduced to achieve stable power supply and introduce electric vehicles for official use and tourism business. Solar cells and small wind mills subject to stand-alone utilization will be arranged along sightseeing roads in the island, on tourism facilities and sightseeing infrastructural facilities. Careful considerations will be given on introduction and arrangement of the new energies for harmony with scenery of the island. Transmission wires related to the new energy utilization will be laid underground. (NEDO)

    South African townships have among the highest rates of HIV infection in the world. Considerable research on understanding the high rates of HIV transmission in this country has identified alcohol use as a critical factor in driving the HIV epidemic. Although the relationship between alcohol use and sexual risk-taking is well documented, less is known about how other factors, such as food insecurity, might be important in understanding alcohol's role in sexual risk-taking. Furthermore, prior research has highlighted how patterns of alcohol use and sexual risk-taking tend to vary by gender. We examined how food insecurity is related to both alcohol use and sexual risk-taking. We administered anonymous community surveys to men (n = 1,137) and women (n = 458) residing within four contiguous Black African townships outside of Cape Town, South Africa. In multivariate linear regression, we found that food insecurity was related to having higher numbers of male sex partners and condom-protected sex acts among women only. These relationships, however, were fully mediated by women's alcohol use. Among men, we found that food insecurity was negatively related to unprotected sex; that is, men with greater food security reported more unprotected sex acts. Unlike the results found among women, this relationship was not mediated by alcohol use. Food insecurity appears to be an important factor in understanding patterns of sexual risk-taking in regards to gender and alcohol use, and may serve as an important point of intervention for reducing HIV transmission rates.

    This study identifies potential organizational barriers associated with the implementation of the Chinese National Essential Medicines Policy (NEMP) in rural primary health care institutions. We used a multistage sampling strategy to select 90 township hospitals from six provinces, two from each of eastern, middle, and western China. Data relating to eight core NEMP indicators and institutional characteristics were collected from January to September 2011, using a questionnaire. Prescription-associated indicators were calculated from 9000 outpatient prescriptions selected at random. We categorized the eight NEMP indicators using an exploratory factor analysis, and performed linear regressions to determine the association between the factor scores and institution-level characteristics. The results identified three main factors. Overall, low levels of expenditure of medicines (F1) and poor performance in rational use of medicines (F2) were evident. The availability of medicines (F3) varied significantly across both hospitals and regions. Factor scores had no significant relationship with hospital size (in terms of number of beds and health workers); however, they were associated with revenue and structure of the hospital, patient service load, and support for health workers. Regression analyses showed that public finance per health worker was negatively associated with the availability of medicines (p finance from local governments may reduce medicine stock lines of township hospitals and lead them to seek alternative sources of income, jeopardizing their capacity to meet the needs of local consumers.

    Transactional sex has not been studied much among men who have sex with men in Africa. Consequently, little is understood about attitudes towards the practice, the circumstances that give rise to it, or how transactional sex relationships are managed. We conducted in-depth interviews with 81 black men aged 20–44 from four low-resourced townships in Tshwane, South Africa. Transactional sex was a widely used strategy for initiating and sustaining relationships with regular and casual partners, and was motivated by both the need for subsistence and for consumption. Alcohol-based exchanges, in particular, provided men in the townships with a covert and safe platform to communicate erotic, sexual and romantic attraction to other men and bars and other drinking places were a popular venue for meeting potential sexual partners. The majority of ‘feminine-identifying’ men had engaged in transactional sex as the providers of money and material goods compared to men who identified as either ‘masculine’ or as ‘both masculine and feminine’. Surprisingly, however, this did not necessarily give them greater control in these relationships. Our study provides an initial foray into a complex socio-sexual phenomenon and suggests that gender identity is an important construct for understanding transactional sex relationships among men in Africa.

    Full Text Available Among the crimes in the South African black townships, mob justice has become a growing concern. Some questions that need to be asked are: Is our police force doing enough to protect the ordinary citizens of this country? If the situation continues, will all suspects be killed in the same manner or will there be a solution to change the situation? What is the impact of mob justice on the families of the victims and the witnesses of the brutal acts? How long are we going to live as a traumatised nation as a result of these violent acts? Is there any hope that our nation will ever have the peace it deserves in the context of democracy? This article intends to investigate the impact of the mob justice system and find out what the role of the Christian church should be in the midst of this escalating violence. This study aims to unveil the negative impact of mob justice on the lives of many township South Africans and giving pastoral-biblical suggestions of the church’s role in the elimination of this kind of brutality.

  8. Girls want money, boys want virgins: the materiality of love amongst South African township youth in the context of HIV and AIDS.

    How do young South Africans give meaning to love? In this paper we draw on findings from an interview study to examine the ways in which young Africans, aged 16 to 17 years in a poor township in KwaZulu-Natal province, express ideals of love and romance. Their claims to love we show are strategic advantages as they negotiate poverty and economic marginalisation. Girls' ideals of love are tied to their aspirations towards middle-class consumerism. Love becomes inseparable from the idealisation of men who provide. Upholding provider masculinity is a strategic means to claim money, fashionable clothes and prestige. Unlike girls, the boys' love investments were focused on farm girls from rural areas in South Africa. Farm girls were constructed as virgins with little investment in commodification. Farm girls are a strategic option through which boys' economic marginalisation experienced in the township girls is reconciled through an exalted masculinity. Love is produced by particular sets of economic and social circumstances through which gender inequalities are reproduced, and should be taken more seriously in working with young people to address gendered social environments and HIV risk.

  12. Ginger Extract Inhibits Biofilm Formation by Pseudomonas aeruginosa PA14

    Kim, Han-Shin; Park, Hee-Deung

    2013-01-01

    Bacterial biofilm formation can cause serious problems in clinical and industrial settings, which drives the development or screening of biofilm inhibitors. Some biofilm inhibitors have been screened from natural products or modified from natural compounds. Ginger has been used as a medicinal herb to treat infectious diseases for thousands of years, which leads to the hypothesis that it may contain chemicals inhibiting biofilm formation. To test this hypothesis, we evaluated ginger’s ability to inhibit Pseudomonas aeruginosa PA14 biofilm formation. A static biofilm assay demonstrated that biofilm development was reduced by 39–56% when ginger extract was added to the culture. In addition, various phenotypes were altered after ginger addition of PA14. Ginger extract decreased production of extracellular polymeric substances. This finding was confirmed by chemical analysis and confocal laser scanning microscopy. Furthermore, ginger extract formed noticeably less rugose colonies on agar plates containing Congo red and facilitated swarming motility on soft agar plates. The inhibition of biofilm formation and the altered phenotypes appear to be linked to a reduced level of a second messenger, bis-(3′-5′)-cyclic dimeric guanosine monophosphate. Importantly, ginger extract inhibited biofilm formation in both Gram-positive and Gram-negative bacteria. Also, surface biofilm cells formed with ginger extract detached more easily with surfactant than did those without ginger extract. Taken together, these findings provide a foundation for the possible discovery of a broad spectrum biofilm inhibitor. PMID:24086697

The major goal of continuing education is to improve and promote quality care. Continuing education is also important to an organization's strategic plan because of its positive influence on the quality of care provided. The purpose of this study was to identify the determinants of and opportunities for continuing education among health care professionals at public health facilities in Jimma township.Methods: A cross-sectional study of 319 health care professionals working in the public health facilities of Jimma township was conducted from January 10, 2012 to February 28, 2012. A self-administered questionnaire was used to collect the data. First, descriptive analysis was done to describe the characteristics of the study participants. Finally logistic regression was then used to determine the independent predictors of continuing education.Results: Only 70 (25% of the study participants were participating in continuing education. As working experience increased, participation in continuing education did not steadily increase. The working hours per week were higher for diploma holders than for those with any other qualification. One hundred and fifty-three (71.8% participants mentioned lack of support from their current employer as the reason for not participating in continuing education. Health care professionals with a lack of support from management were 2.4 times more likely not to participate in advanced education. Health care professionals with lack of funding were 0.3 times less likely to participate in advanced education. Health care professionals with lack of resources other than financial were 2.2 times more likely not to participate in

    The report describes an illegal waste disposal site in east central Pennsylvania and its effect on groundwater in the area surrounding the site. The Crossley Farm (Hereford Groundwater) site is in the Huffs Church community of Hereford Township, Berks County. Illegal waste disposal activities reportedly occurred at the site from the mid-1960's to mid-1970's. About 250 residents live hydrogeological downgradient of the site (within two miles) and another 200 live within one-half mile upgradient of the site. The Pennsylvania Department of Environmental Resources has collected groundwater samples in 1983 and the EPA has collected samples in 1986. The estimated exposures are to substances (trichloroethylene and tetrachloroethylene in particular) in groundwater at concentrations that with long-term exposure can cause adverse health effects to the population

    Full Text Available Titanium dioxide-polyaniline/polyamide 6 (TiO2-PANI/PA6 composite nanofibers were prepared by in situ polymerization of aniline in the presence of PA6 nanofibers and a sputtering-deposition process with a high purity titanium sputtering target. TiO2-PANI/PA6 composite nanofibers and PANI/PA6 composite nanofibers were fabricated for ammonia gas sensing. The ammonia sensing behaviors of the sensors were examined at room temperature. All the results indicated that the ammonia sensing property of TiO2-PANI/PA6 composite nanofibers was superior to that of PANI/PA6 composite nanofibers. TiO2-PANI/PA6 composite nanofibers had good selectivity to ammonia. It was also found that the content of TiO2 had a great influence on both the morphology and the sensing property of TiO2-PANI/PA6 composite nanofibers.

    It is intended to examine the adsorption of protactinium on glass in relation to pH, presence of complexing agents concentration and type of electrolytes. The study was made by using carrier-free 233 Pa solution and Pyrex glass tube was selected as adsorbent glass material surface. The adsorption curve of protactinium on glass surface as a function of the pH of the tracer solution showed the existence of two pronounced adsorption regions. It was found that this adsorption can be reduced by using electrolytes or complexing agents. Desorption of protactinium previously adsorbed on the Pyrex glass tube was also studied. Hidrochloric, oxalic and hydrofluoric acid solutions were used for the desorption experiments. (Author) [pt

    A rail electromagnetic accelerator is one of the most reliable and simple devices for accelerating macroparticles up to high velocity. These accelerators allow scientists to carry out fundamental and applied investigations to study both equation-of-state of materials at high pressure due to high velocity encounters, and creation of conditions for shock thermonuclear fusion. In the department ''Energophyzika'' LS and PA ''Soyuz'' range was created. It was equipped with an inductor with storage capacity up to 12.5 MJ energized by a solid propellant MHD generator and a capacitor bank (energy capacity up to 6 MJ). These systems deliver currents of 1 MA and 2 MA, respectively. Diagnostic, recording, and autocalculation systems allow use of as many as 120 data channels with acquisition frequency up to 10 MHz. Recent technical successes in railgun construction, using special methods to compact plasma armature and produce high velocity trailing contact, creation of hybrid armatures, and optimizing acceleration made possible to gain velocities in the range of 6.2 to 6.8 km/s (masses of 3.8 to 10 g) and velocities 2.7 to 3.8 km/s (masses of 50 to 100 g) on railguns with length 2 to 4 m

    The Mayak Production Association (Mayak PA) was established in the late 1940's to produce plutonium for the Soviet Nuclear Weapons Programme. In total, seven reactors and two reprocessing plants have been in operation. Today, the area comprises both military and civilian reactors as well as reprocessing and metallurgical plants. Authorized and accidental releases of radioactive waste have caused severe contamination to the surrounding areas. In the present study, [alpha]-spectrometry and inductively coupled plasma-mass spectrometry (ICP-MS) have been used to determine plutonium activities and isotope ratios in soil and sediment samples collected from reservoirs of the Techa River at the Mayak area and downstream Techa River. The objective of the study was to determine the total inventory of plutonium in the reservoirs and to identify the different sources contributing to the plutonium contamination. Results based on [alpha]-spectrometry and ICP-MS measurements show the presence of different sources and confirmed recent reports of civilian reprocessing at Mayak. Determination of activity levels and isotope ratios in soil and sediment samples from the Techa River support the hypothesis that most of the plutonium, like other radionuclides in the Techa River, originated from the very early waste discharges to the Techa River between 1949 and 1951. Analysis of reservoir sediment samples suggest that about 75% of the plutonium isotopes could have been released to Reservoir 10 during the early weapons production operation of the plant, and that the majority of plutonium in Reservoir 10 originates from discharges from power production or reprocessing. Enhanced 240Pu/239Pu atom ratios in river sediment upper layers (0-2 cm) between 50 and 250 km downstream from the plant indicate a contribution from other, non-fallout sources.

    There is an increasing awareness of the role played by the food retail characteristics in determining individuals' healthy food purchasing and consumption behaviors. The perceived costs of healthier food alternatives have been shown to contribute negatively to individual's food choices in developed societies. However, there is still a dearth of knowledge regarding this phenomenon in low to middle income countries particularly in Africa. This study explored health club member's experiences in buying healthier food options and compared their perceived cost of selected healthier and less healthy foods with actual market costs in a South African township. A cross-sectional study design using quantitative and qualitative research methods. The study was conducted in Khayelitsha, a township in the Western Cape Province in South Africa. Participants were 50 members of a health club, mostly female and above 50 years of age. The study was conducted in three phases. The first phase involved interviews with all 50 health club members. During the second phase ten purposively selected members participated in in-depth interviews based on their unhealthy food-purchasing and consumption patterns identified in the first phase. The third phase involved food price audits from supermarkets as well as convenient stores located in the study setting. Quantitative data were subjected to descriptive statistical analysis, while content analysis was used to analyze qualitative data. Most of the members were illiterate and unemployed, largely dependent on government grants. Qualitative findings showed that low household incomes, their inability to read and interpret nutritional information and personal food preferences contributed to Health club members' unhealthy food-purchasing behaviour. When objectively measured in local stores, the healthier food options proved to be more expensive than their less healthy equivalents. This was consistent with subjects' perceptions about the relative cost

    Fibrinolytics such as recombinant tissue plasminogen activator (rt-PA) are used to treat thrombotic disease such as acute myocardial infarction (AMI) and ischemic stroke. Interest in increasing efficacy and reducing side effects has led to the study of adjuncts such as GP IIb-IIIa inhibitors and ultrasound (US) enhanced thrombolysis. Currently, GP IIb-IIIa inhibitor and fibrinolytic treatment are often used in AMI, and are under investigation for stroke treatment. However, little is known of the efficacy of combined GP IIb-IIIa inhibitor, fibrinolytic and ultrasound treatment. We measure the lytic efficacy of rt-PA, eptifibatide (Epf) and 120 kHz ultrasound treatment in an in-vitro human clot model. Blood was drawn from 15 subjects after IRB approval. Clots were made in 20 microL pipettes, and placed in a water tank for microscopic visualization during lytic treatment. Clots were exposed to control, rt-PA (rt-PA), eptifibatide (Epf), or rt-PA+eptifibatide (rt-PA + Epf), with (+US) or without (-US) ultrasound for 30 minutes at 37 degrees C in human plasma. Clot lysis was measured over time, using a microscopic imaging technique. The fractional clot loss (FCL) and initial lytic rate (LR) were used to quantify lytic efficacy. LR values for (- US) treated clots were 0.8+/-0.1(control), 1.8+/-0.3 (Epf), 1.5+/-0.2 (rt-PA), and 1.3+/-0.4 (rt-PA + Epf) (% clot width/minute) respectively. In comparison, the (+ US) group exhibited LR values of 1.6+/-0.2 (control), 4.3+/-0.4 (Epf), 6.3+/-0.4 (rt-PA), and 4.6+/-0.6 (rt-PA + Epf). For (- US) treated clots, FCL was 6.0+/-0.8 (control), 9.2+/-2.5 (Epf), 15.6+/-1.7 (rt-PA), and 28.0+/-2.2% (rt-PA + Epf) respectively. FCL for (+ US) clots was 13.5+/-2.4 (control), 20.7+/-6.4 (Epf), 44.4+/-3.6 (rt-PA) and 30.3+/-3.6% (rt-PA + Epf) respectively. Although the addition of eptifibatide enhances the in-vitro lytic efficacy of rt-PA in the absence of ultrasound, the efficacy of ultrasound and rt-PA is greater than that of combined

    The only acute treatment of ischemic stroke approved by the health authorities is tissue recombinant plasminogen activator (tPA)-induced thrombolysis. Under physiological conditions, tPA, belonging to the serine protease family, is secreted by endothelial and brain cells (neurons, astrocytes, microglia, oligodendrocytes). Although revascularisation induced by tPA is beneficial during a stroke, research over the past 20 years shows that tPA can also be deleterious for the brain parenchyma. Thus, in this review of the literature, after a brief history on the discovery of tPA, we reviewed current knowledge of mechanisms by which tPA can influence brain function in physiological and pathological conditions.

    Owiti, John Arianda

    2008-01-01

    This article is extracted from a doctoral thesis that was supported by a research grant from the International Development Research Centre of Canada (IDRC)'s Ecosystem Approaches to Human Health Training Award, the Royal Anthropological Institute of Great Britain and Northern Ireland's Emslie Horniman Scholarship Fund and McGill University, Faculty of Graduate Studies and Research's Humanities and Social Sciences Research Award. This study used a broad theoretical framework encompassing an ecosystem approach to HIV-1/AIDS that partly investigated the nexus between local knowledge of tuberculosis (TB) and HIV-1/AIDS. According to the Turkana of Lodwar township, Kenya, HIV-1/AIDS and TB are largely contagious and are attributed to impersonal and natural causes. In addition, in line with biomedical knowledge, the Turkana's local knowledge emphasises a conceptual link between TB and HIV-1/AIDS. The study also demonstrates that factors of the ecosystem such as kaada, poverty, widow inheritance, migration and other socio-cultural practices play an influential role in the vulnerability of the Turkana to the contraction and transmission of both TB and HIV-1/AIDS. The article posits an integrated approach to the prevention of TB and HIV-1 and to the management of AIDS and TB.

    Objective: To assess the degree of poisoning in farmers using the erythrocyte acetylcholinesterase (AChE) test before and after the exposure to pesticides in townships in central Benin (Glazoué and Savè) and to identify the associated risk factors. Methods: Using a cross-sectional study design, we recruited 264 farm pesticide sprayers, who have been working for at least 5 years. They completed a questionnaire and underwent the AChE test using the Test-mate Model 400 device (EQM Research Inc.) with a photometric sensor, based on the works of Ellman. Results: Organophosphate/pyrethroids were the most common pesticides used by at least 72.96% of the farmworkers. We observed an inhibition of AChE between pre-exposure and post-exposure (P = .002) for 60.61% of the farmworkers. Among them, 11.88% displayed more than 20% AChE inhibition. Conclusions: Pesticide poisoning is a reality, and AChE monitoring is urgently needed for farmworker surveillance. PMID:28469452

  12. Formerly utilized MED/AEC Sites Remedial Action Program. Radiological survey of the Pennsylvania Railroad Landfill Site, Burrell Township, Pennsylvnia. Final Report

    International Nuclear Information System (INIS)

    1979-02-01

    A radiological survey was conducted at the Pennsylvania Railroad Landfill Site in Burrell Township, Pennsylvania. In 1956 and 1957, approximately 11,600 tons of radioactive material was dumped at this site and was apparently scattered over an area of loss than 10 acres. The survey included measurement of the following: external gamma radiation at 1 m above the surface and at the surface throughout the site; beta--gamma dose rates at 1 cm from the surface throughout the site; concentrations of 226 Ra and 238 U in surface and subsurface soil on the site; concentrations of 210 Pb, 226 Ra, 230 Th, and 238 U in subsurface water on the site and in surface water on and near the site; and the extent of atmospheric transport of 222 Rn and progeny from the site. The general location of the residues transported to the site, except possibly small, scattered quantities of materials, was determined from the survey. In some areas on the site, beta--gamma dose rates of 1 cm from the surface were above pertinent guidelines.Analyses of sediment from water samples taken from drainage areas near the site indicate that some radioactive material is being carried from the site by surface run-off. Results of this survey indicate that there is no significant atmospheric transport of 222 Rn from the site

    1994-12-01

    The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and right-of-way (ROW) management practices. This report presents the results of a survey conducted over the period of August 3-4, 1992, at the Cassadaga wetlands crossing in Gerry Township, Chautauqua County, New York. The pipeline at this site was installed during February and March 1981. After completion of pipeline installation, the ROW was fertilized, mulched, and seeded with annual ryegrass. Two adjacent sites were surveyed in this study: a forested wetland and an emergent wetlands Eleven years after pipeline installation, the ROW at both sites supported diverse vegetative communities. Although devoid of large woody species, the ROW within the forested wetland had a dense vegetative cover. The ROW within the emergent wetland had a slightly less dense and more diverse vegetative community compared with that in the adjacent natural areas (NAs). The ROW within the emergent wetland also had a large number of introduced species that were not present in the adjacent NAs. The ROW, with its emergent marsh plant community, provided habitat diversity within the forested wetlands Because the ROW contained species not found within the adjacent NAs, overall species diversity was increased.

    Full Text Available This research analyzed the prevalence of water sanitation at the household level against gastrointestinal disease occurrence in the urban slum setting of South Okkalapa Township, Myanmar, using cross-sectional study design techniques. A total of 364 household respondents were interviewed face to face by well-trained research assistants using structured questionnaires. Chi-square tests and multiple logistic regression analyses were used to determine the association between independent and dependent variables. Results showed that the source of household water (OR: 13.58, 95% CI: 6.90-26.74, and the types of drinking water (OR: 1.85, 95% CI: 0.92-3.71, were significantly associated with gastrointestinal diseases (p-value<0.05. After adjustment for confounding factors, this study found that occupation (AOR: 2.63, 95% CI: 1.25-5.54, employment status (AOR: 2.25, 95% CI: 1.01-5.01, type of household toilet (AOR: 8.66, 95% CI: 4.03-18.60, sources of household water (AOR: 6.56, 95% CI: 2.86-15.08, and the method of vector control (AOR: 3.12, 95% CI: 1.37-7.30 were all significantly associated with gastrointestinal diseases (p-value<0.05. Health education and appropriate technology for household water, sanitary latrines, environmental sanitation and waste disposal, and the implementation of policies focusing on systematic water management are therefore urgently required to control the spread of waterborne diseases.

    1990-01-01

    The 12-acre Woodland Route 72 Dump site is an abandoned hazardous waste dump in Woodland Township, Burlington County, New Jersey. The site is being remediated concurrently with another abandoned dump. Several chemical manufacturing firms dumped chemicals and other wastes into trenches and lagoons or burned the waste at the sites from the early 1950s to 1962. The primary contaminants of concern affecting the surface soil, sediment, sludge, debris, and ground water are VOCs including benzene, toluene, TCE and xylenes; organics including PAHs, pesticides, and phenols; radionuclides (e.g., uranium and thorium series); and metals including lead and chromium. The selected remedial action for the site includes excavation, further characterization, and offsite disposal at a permitted facility of 54,000 cubic yards (total from both sites) of contaminated surface soil, sludges, debris and sediment; offsite disposal of 19 cubic yards (total from both sites) of radiologically contaminated surface materials including a drum of radioactive pellets; ground water pumping and treatment with treatment to be determined during design. The total estimated present worth cost for the concurrent remedial actions at the Route 72 and Route 532 sites is $142,200,000

  20. New Insight into Metal Ion-Driven Catalysis of Nucleic Acids by Influenza PA-Nter.

    Directory of Open Access Journals (Sweden)

    Daria Kotlarek

    Full Text Available PA subunit of influenza RNA-dependent RNA polymerase deserves constantly increasing attention due to its essential role in influenza life cycle. N-terminal domain of PA (PA-Nter harbors endonuclease activity, which is indispensable in viral transcription and replication. Interestingly, existing literature reports on in vitro ion preferences of the enzyme are contradictory. Some show PA-Nter activity exclusively with Mn2+, whereas others report Mg2+ as a natural cofactor. To clarify it, we performed a series of experiments with varied ion concentrations and substrate type. We observed cleavage in the presence of both ions, with a slight preference for manganese, however PA-Nter activity highly depended on the amount of residual, co-purified ions. Furthermore, to quantify cleavage reaction rate, we applied fluorescence cross-correlation spectroscopy (FCCS, providing highly sensitive and real-time monitoring of single molecules. Using nanomolar ssDNA in the regime of enzyme excess, we estimated the maximum reaction rate at 0.81± 0.38 and 1.38± 0.34 nM/min for Mg2+ and Mn2+, respectively. However, our calculations of PA-Nter ion occupancy, based on thermodynamic data, suggest Mg2+ to be a canonical metal in PA-Nter processing of RNA in vivo. Presented studies constitute a step toward better understanding of PA-Nter ion-dependent activity, which will possibly contribute to new successful inhibitor design in the future.

    Full Text Available Through a straightforward approach, a new meltable, halogen-free, nitrogen-phosphorus-based flame retardant (FR, 6-(2-(4,6-diamino-1,3,5-triazin-2-ylethyl dibenzo[c,e][1,2]oxaphosphinine 6-oxide (DTE-DOPO was synthesized and incorporated in polyamide 6 (PA6. It was proved that a very low phosphorus content of 1.46 wt% for DTE-DOPO additive improved the flame retardancy of PA6, leading to a non-flammable material. The performance of the new additive was compared to that of the commercially-available Exolit® OP 1230. The PA6 formulations were evaluated by measuring the rheological, mechanical, and flammability behavior. Using compounding by melt extrusion, 17 wt% additives was introduced into PA6 matrix and the corresponding formulations were characterized. The results evidenced a higher homogeneity of DTE-DOPO with PA6, a high thermal stability with a catalyzing decomposition effect on PA6 caused by the presence of the new developed FR, enhanced elasticity for the PA6/DTE-DOPO formulation and a V0 rating for both formulations. Thermal and fire analysis indicated a primary gas-phase activity, combined with a complete suppression of the self-sustained burning for the PA6/DTE-DOPO formulation.

    PA-MSHA, a genetically engineered Pseudomonas aeruginosa (PA) strain, is currently under investigation as a new anti-cancer drug. It can induce cell cycle arrest and apoptosis in different human cancer cells, including hormone receptor negative breast cancer cells. However, the underlying mechanism of tumor lethality mediated by PA-MSHA remains to be fully investigated. The effect of PA-MSHA on human hormone receptor negative breast cancer cells was analyzed by morphological measurement, western blot, cell proliferation assay and mouse xenograft model. PA-MSHA was found to induce endoplasmic reticulum (ER) stress in breast cancer cell lines through the IRE1 signaling pathway. Inhibiting autophagy potentiated the cytotoxic effect of PA-MSHA while treating breast cancer cell lines. In mouse xenograft model, PA-MSHA produced more pronounced tumor suppression in mice inoculated with IRE1 gene knockdown. MDA-MB-231HM cells. These findings demonstrated inhibiting autophagy together with PA-MSHA might be a promising therapeutic strategy in treating hormone receptor negative breast cancer cells

  7. Collective and single-particle excitations in the heavy deformable nuclei 234U, 233U, 231Th, 230Pa and 232Pa

    2010-01-01

    In this thesis five heavy deformed isotopes from the mass region A≥230, namely 234 U, 233 U, 231 Th, 230 Pa and 232 Pa, were investigated by means of deuteron-induced neutron transfer reactions. The even-even isotope 234 U has been studied with the 4π-γ-spectrometer MINIBALL at the Cologne Tandem accelerator. Excited nuclei in the isotope 234 U were produced using the reaction 235 U(d,t) at a beam energy of 11 MeV. The target thickness was 3.5 mg/cm 2 . The analysis of the γγ-coincidence data yielded a reinterpretation of the level scheme in 12 cases. Considering its decay characteristics, the 4 + state at an excitation energy of 1886.7 keV is a potential candidate for a two-phonon vibrational state. The isotopes 233 U, 231 Th, 230 Pa and 232 Pa were investigated at the Munich Q3D spectrometer. For each isotope an angular distribution with angles between 5 and 45 were measured. In all four cases the energy of the polarized deuteron beam (vector polarization of 80%) was 22 MeV. As targets 234 U (160 μg/cm 2 ), 230 Th (140 μg/cm 2 ) and 231 Pa (140 μg/cm 2 ) were used. The experimental angular distributions were compared to results of DWBA calculations. For the odd isotope 233 U spin and parity for 33 states are assigned and in the other odd isotope 231 Th 22 assignments are made. The excitation spectra of the two odd-odd isotopes 230 Pa and 232 Pa were investigated for the first time. For the isotope 230 Pa 63 states below an excitation energy of 1.5 MeV are identified. Based on the new experimental data the Nilsson configuration of the ground state is either 1/2[530] p -5/2[633] n or 1/2[530] p +3/2[631] n . In addition 12 rotational bands are proposed and from this six values for the GM splitting energy are deduced as well as two new values for the Newby shift. In the other odd-odd isotope 232 Pa 40 states below an excitation energy of 850 keV are observed and suggestions for the groundstate band and its GM partner are made. From this one GM splitting

    Full Text Available Gears made of plastic-based materials are anticorrosive, resistant to magnetic environments, and light and have pulse decay, low noise, and self-lubrication properties, and therefore their usage areas are widening every single day. In this experiment, the working conditions of 30% fibreglass PA 66 (PA 66 GFR 30 plastic material with PA 66 (PA 66 GFR 30 plastic material and AISI 8620 couple gear are observed. Usage of PA 66 GFR 30 material as gear material at 56.75 Nm constant load and 750 rpm, 1000 rpm, and 1500 rpm was analysed. The load capacity damage formation of the material was also analysed. The tooth surface temperature, corrosion depth of the tooth profile, tooth damage, and the tooth surface were examined with an scanning electron microscopy (SEM and the corrosive behaviour of gears was analysed.

  9. Exogenous t-PA administration increases hippocampal mature BDNF levels. plasmin- or NMDA-dependent mechanism?

    Full Text Available Brain-derived neurotrophic factor (BDNF through TrkB activation is central for brain functioning. Since the demonstration that plasmin is able to process pro-BDNF to mature BDNF and that these two forms have opposite effects on neuronal survival and plasticity, a particular attention has been paid to the link between tissue plasminogen activator (tPA/plasmin system and BDNF metabolism. However, t-PA via its action on different N-methyl-D-aspartate (NMDA receptor subunits is also considered as a neuromodulator of glutamatergic transmission. In this context, the aim of our study was to investigate the effect of recombinant (rt-PA administration on brain BDNF metabolism in rats. In the hippocampus, we found that rt-PA (10 mg/kg administration induced a progressive increase in mature BDNF levels associated with TrkB activation. In order to delineate the mechanistic involved, plasmin activity was assessed and its inhibition was attempted using tranexamic acid (30 or 300 mg/kg, i.v. while NMDA receptors were antagonized with MK801 (0.3 or 3 mg/kg, i.p. in combination with rt-PA treatment. Our results showed that despite a rise in rt-PA activity, rt-PA administration failed to increase hippocampal plasmin activity suggesting that the plasminogen/plasmin system is not involved whereas MK801 abrogated the augmentation in mature BDNF levels observed after rt-PA administration. All together, our results show that rt-PA administration induces increase in hippocampal mature BDNF expression and suggests that rt-PA contributes to the control of brain BDNF synthesis through a plasmin-independent potentiation of NMDA receptors signaling.

    To shorten vegetative stage and induce transition from vegetative to reproductive stage in orchids, we overexpressed Phalaenopsis amabilis Flowering LocusT (PaFT) gene under the control of Ubiquitin promoter into protocorm of Indonesian Wild Orchid Phalaenopsis amabilis (L.) Blume. The dynamic expression of vegetative gene Phalaenopsis Homeobox1 (POH1) and flowering time gene PaFT has been analyzed. Accumulation of mRNA was detected in shoot and leaves of both transgenic and non transgenic plants by using Reverse transcriptase-PCR (RT-PCR) with specific gene primers for POH1 and PaFT in 24 months old plants. To analyze the POH1 and PaFT genes, three pairs of degenerate primers PaFT degF1R1, F2R2 and F3R3 that amplified 531 bp PaFT cDNA were used. We detected 700 bp PaFTcDNA from leaves and shoots of transgenic plants, but not in NT plants. POH1 mRNA was detected in plants. PaFT protein consists of Phospatidyl Ethanolamine-Binding Protein (PEBP) in interval base 73-483 and CETS family protein at base 7-519, which are important motif for transmembrane protein. We inserted Ubipro::PaFT/pGAS101 into P. amabilis protocorm using Agrobacterium. Analysis of transgenic plants showed that PaFTmRNA was accumulated in leaves of 12 months after sowing, although it is not detected in non transgeic plants. Compare to the wild type (NT plants), ectopic expression of PaFT shows alter phenotype as follows: 31% normal, 19% with short-wavy leaves, 5% form rosette leaves and 45% produced multishoots. Analysis of protein profiles of trasgenic plants showed that a putative PaFT protein (MW 19,7 kDa) was produced in 1eaves and shoots.This means that at 12 months, POH1 gene expression gradually decreased/negatively regulated, the expression of PaFT gene was activated, although there is no flower initiation yet. Some environmental factors might play a role to induce inflorescens. This experiment is in progress.

    South Africa has high rates of traumatic experiences and alcohol abuse or dependence, especially among women. Traumatic experiences often result in symptoms of posttraumatic stress disorder (PTSD), and PTSD has been associated with hazardous drinking. This article examines the relationship between traumatic events and hazardous drinking among women who patronized alcohol-serving venues in South Africa and examines PTSD as a mediator of this relationship. A total of 560 women were recruited from a Cape Town township. They completed a computerized assessment that included alcohol consumption, history of traumatic events, and PTSD symptoms. Mediation analysis examined whether PTSD symptoms mediated the relationship between the number of traumatic event categories experienced (range: 0-7) and drinking behavior. The mean Alcohol Use Disorders Identification Test score in the sample was 12.15 (range: 0-34, SD = 7.3), with 70.9% reaching criteria for hazardous drinking (AUDIT > 8). The mean PTSD score was 36.32 (range: 17-85, SD = 16.3),with 20.9% meeting symptom criteria for PTSD (PTSD Checklist with 20.9% meeting symptom criteria for PTSD (PTSD Checklist-Civilian Version ≥ 50). Endorsement of traumatic experiences was high, including adult emotional (51.8%), physical (49.6%), and sexual (26.3%) abuse; childhood physical (35.0%) and sexual (25.9%) abuse; and other types of trauma (83%). All categories of traumatic experiences, except the "other" category, were associated with hazardous drinking. PTSD symptoms mediated 46% of the relationship between the number of traumatic categories experienced and drinking behavior. Women reported high rates of hazardous drinking and high levels of PTSD symptoms, and most had some history of traumatic events. There was a strong relationship between traumatic exposure and drinking levels, which was largely mediated by PTSD symptoms. Substance use interventions should address histories of trauma in this population, where alcohol may be

    To examine the associations between resilience, community belonging, and social participation, and the moderating effect of resilience on the association between community belonging and social participation among community-dwelling older adults. Cross-sectional; secondary analyses of the Eastern Townships Population Health Survey. Community. A sample (N=4541) of women (n=2485) and men (n=2056) aged ≥60 years was randomly selected according to area. Most participants had community belonging, and resilience were collected by phone interviewer-administered questionnaire. A social participation scale measured frequency of participation in 8 community activities. A 4-point Likert scale ranging from "very strong" to "very weak" estimated sense of belonging to the local community. Social participation and sense of belonging questions came from Statistics Canada surveys. Resilience was assessed with the 10-item Connor-Davidson Resilience Scale, capturing the ability to cope with adversity. Controlling for age, education, and psychological distress, greater resilience and community belonging were associated with greater social participation among women (R 2 =.13; Pcommunity belonging and social participation varied as a function of resilience, especially in men. Greater community belonging further enhanced social participation, especially among women (P=.03) and men (Pcommunity belonging and social participation among community-dwelling older women and, especially, men. Interventions targeting social participation should consider the potential impact of resilience on improving community belonging. Future studies should investigate why resilience moderates associations between community belonging and social participation, and how to enhance resilience among older adults. Crown Copyright © 2017.

  16. Prospects for Searching for Time-Reversal Violation In Pa-229

    Science.gov (United States)

    Singh, Jaideep

    2017-09-01

    Certain pear-shaped nuclei are expected to have enhanced sensitivity to time-reversal and parity-violating interactions originating within the nuclear medium. In particular, Pa-229 is thought to be about 100,000 times more sensitive than Hg-199 which currently sets some of the most stringent limits for these types of interactions. Several challenges would first have to be addressed in order to take advantage of this discovery potential. First, there is not currently a significant source of Pa-229; however, there are plans to harvest Pa-229 from the FRIB beam dump. Second, the spin-5/2 nucleus of Pa-229 limits its coherence time while also making it sensitive to systematic effects related to local field gradients. On the other hand, this also gives Pa-229 an additional source of signal in the form of a magnetic quadrupole moment (MQM) which violates the same symmetries as an EDM but is not observable in spin-1/2 systems. Third, in order to compensate for the small atom numbers and short coherence times, the Pa-229 atoms would have to be probed with exceptionally large electric & magnetic fields that are only possible if Pa-229 is a part of a polar molecule or embedded inside of an optical crystal. I will present an our plans to test some of these concepts using stable Pr-141.

    The present study focuses on the fabrication and mechanical property evaluation of PA-6/MWCNT nanocomposites reinforced with microwave-functionalized MWCNTs. The MWCNTs were subjected to microwave radiation in the solution of H2SO4 and HNO3 for 3 minutes, with the aim of achieving better and faster functionalization. The change observed in the crystal structure of PA-6 matrix after CNT addition suggested improved nucleation due to well-dispersed MWCNTs after functionalization. The tensile strength of PA-6 increased by approx. 12 % and 15 % after addition of pristine and functionalized MWCNTs, respectively. This was credited to improved interaction between CNTs and PA-6 matrix. The dispersion quality of CNTs in PA-6 matrix was verified by FEG-SEM, while the fractography of composites revealed polymer sheathing of PA-6 matrix around CNTs. This again contributed in improving the elongation of the composites by approx. 10 %. The wear resistance of the composites also improved appreciably, irrespective of the applied load. The specific wear rate of PA-6/CNT nanocomposite reinforced with functionalized MWCNTs increased by approx. 60 to 70 %, while coefficient of friction reduced by approx. 30 to 40%.

    231 Pa and two Th isotopes ( 230 Th and 228 Th) were measured using large-volume water samples from the western North Pacific. Although 231 Pa and 230 Th have uniform source distributions (by decay of uranium) throughout the oceans, their vertical profiles are discernibly different from each other. The 231 Pa profile shows a mid-depth maximum around 2.5 km, while 230 Th increases monotonically with depth. This demonstrates that these nuclides follow different pathways for their transport and removal from seawater to depositional sinks. The activity ratio of 230 Th/ 231 Pa in seawater increases from one at the surface to four at a depth of 4 to 5 km, which is lower by a factor of 10 than the ratios published for open ocean particulate matter at the same depth horizon. The distribution coefficient, Ksub(D) for Pa, and the fractionation factor, Fsub(Th/Pa), between natural marine particulate matter and seawater are constant with depth at approx. 2 x 10 6 and 10, respectively. This implies that the adsorptive characteristics of deep open ocean particles are independent of particle composition or the content of manganese. The mean residence time of 231 Pa is estimated to be 200 years, which is considerably longer than that of 230 Th, but close to that of 210 Pb. (author)

    The effects of PA21, a novel iron-based and non-calcium-based phosphate binder, on hyperphosphatemia and its accompanying bone abnormality in chronic kidney disease-mineral and bone disorder (CKD-MBD) were evaluated. Rats with adenine-induced chronic renal failure (CRF) were prepared by feeding them an adenine-containing diet for four weeks. They were also freely fed a diet that contained PA21 (0.5, 1.5, and 5%), sevelamer hydrochloride (0.6 and 2%) or lanthanum carbonate hydrate (0.6 and 2%) for four weeks. Blood biochemical parameters were measured and bone histomorphometry was performed for femurs, which were isolated after drug treatment. Serum phosphorus and parathyroid hormone (PTH) levels were higher in the CRF rats. Administration of phosphate binders for four weeks decreased serum phosphorus and PTH levels in a dose-dependent manner and there were significant decreases in the AUC0-28 day of these parameters in 5% PA21, 2% sevelamer hydrochloride, and 2% lanthanum carbonate hydrate groups compared with that in the CRF control group. Moreover, osteoid volume improved significantly in 5% of the PA21 group, and fibrosis volume and cortical porosity were ameliorated in 5% PA21, 2% sevelamer hydrochloride, and 2% lanthanum carbonate hydrate groups. These results suggest that PA21 is effective against hyperphosphatemia, secondary hyperparathyroidism, and bone abnormalities in CKD-MBD as sevelamer hydrochloride and lanthanum carbonate hydrate are, and that PA21 is a new potential alternative to phosphate binders.

    Edaravone, a potent antioxidant, may improve thrombolytic therapy because it benefits ischemic stroke patients on its own and mitigates adverse effects of tissue plasminogen activator (tPA) in preclinical models. However, whether the combined tPA-edaravone therapy is more effective in reducing infarct size than singular treatment is uncertain. Here we investigated this issue using a transient hypoxia-ischemia (tHI)-induced thrombotic stroke model, in which adult C57BL/6 mice were subjected to reversible ligation of the unilateral common carotid artery plus inhalation of 7.5% oxygen for 30 min. While unilateral occlusion of the common carotid artery suppressed cerebral blood flow transiently, the addition of hypoxia triggered reperfusion deficits, endogenous thrombosis, and attenuated tPA activity, leading up to infarction. We compared the outcomes of vehicle-controls, edaravone treatment, tPA treatment at 0.5, 1, or 4 h post-tHI, and combined tPA-edaravone therapies with mortality rate and infarct size as the primary end-points. The best treatment was further compared with vehicle-controls in behavioral, biochemical, and diffusion tensor imaging (DTI) analyses. We found that application of tPA at 0.5 or 1 h--but not at 4 h post-tHI--significantly decreased infarct size and showed synergistic (pedaravone treatment, respectively. The acute tPA-edaravone treatment conferred >50% reduction of mortality, ∼ 80% decline in infarct size, and strong white-matter protection. It also improved vascular reperfusion and decreased oxidative stress, inflammatory cytokines, and matrix metalloproteinase activities. In conclusion, edaravone synergizes with acute tPA treatment in experimental thrombotic stroke, suggesting that clinical application of the combined tPA-edaravone therapy merits investigation.

    Full Text Available Pax transactivation domain interacting protein (PTIP associated protein 1, PA1, was a newly found protein participating in the modulation of transactivity of nuclear receptor super family members such as estrogen receptor (ER, androgen receptor (AR and glucocorticoid receptor (GR. Breast cancer is one of the most life threatening diseases for women and has tight association with estrogen and ER. This study was performed to understand the function of PA1 in breast cancer. The expression of PA1 had been evaluated in a total of 344 primary invasive breast cancer samples and examined the relationship with clinical output, relapse free survival (RFS, breast cancer-specific survival (BCSS. PA1 expression was observed in both nucleus and cytoplasm, however, appeared mainly in nuclear. PA1 nuclear expression was correlated with postmenopausal (P = 0.0097, smaller tumor size (P = 0.0025, negative Ki67 (P = 0.02, positive AR (P = 0.049 and positive ERβ (P = 0.0020. Kaplan-Meier analysis demonstrated PA1 nuclear positive cases seemed to have a longer survival than negative ones for RFS (P = 0.023 but not for BCSS (P = 0.23. In the Cox hazards model, PA1 nuclear protein expression proved to be a significant prognostic univariate parameter for RFS (P = 0.03, but not for BCSS (P = 0.20. In addition, for those patients without lymphnode metastasis PA1 was found to be an independent prognostic factor for RFS (P = 0.025, which was verified by univariate and multivariate analyses. These investigations suggested PA1 expression could be a potential prognostic indicator for RFS in breast cancer.

    The potential for hypothermia as a neuroprotectant during stroke has led to its increase in clinical use. At the same time, combination pharmaceutical therapies for ischemic stroke using recombinant tissue plasminogen activator (rt-PA), and GP IIb-IIIa inhibitors, such as Eptifibatide (Epf ), are under study. However, there is little data on how the reactions triggered by these agents are impacted by temperature. Here, clot lysis during exposure to the combination of rt-PA and Epf is measured in an in vitro human clot model at hypothermic temperatures. The hypothesis is that lytic efficacy of rt-PA and Epf decreases with decreasing temperature. Whole blood clots from 31 volunteers were exposed to rt-PA (0.5 μg/mL) and Epf (0.63 μg/mL) in human fresh-frozen plasma (rt-PA+Epf ), rt-PA alone in plasma (rt-PA Alone), or to plasma alone (Control), at temperatures from 30°C to 37°C, for 30 minutes. Clot lysis was measured using a microscopic imaging technique; the mean fractional clot loss (FCL) at 30 minutes was used to determine lytic efficacy. Temperature had a significant impact on FCL in clots exposed to rt-PA+Epf, with the FCL being lower at 30°C to 36°C than at 37°C. The FCL remained significantly higher for rt-PA+Epf–treated clots than Controls regardless of temperature, with the exception of measurements made at 30°C when no significant differences in the FCL were observed between groups. The use of hypothermia as a neuroprotectant may negatively impact the therapeutic benefit of thrombolytic agents.

    Full Text Available Des processus de réappropriation identitaire et historique, à finalité économique, sont à l’œuvre à l’heure actuelle en Afrique du Sud. Un type de tourisme au caractère authentique et interactif connaît notamment un certain engouement : les Township tours. Il assume un épisode médiatisé de l’histoire du pays, soit l’apartheid urbain, en tentant d’inverser l’image répulsive qui lui est associée. L’attirance pour les townships se nourrit d’un désir de compréhension de la ségrégation raciale institutionnalisée et de la mise à bas d’une politique inique. Paradoxalement, la réputation de dangerosité, de pauvreté et « d’informalité » accolée à ces quartiers noirs semble aussi agir comme un produit d’appel. A travers l’exemple de la province du KwaZulu-Natal, il sera vu que cette activité socio-touristique s’oriente à présent vers un multiculturalisme prudent, porté par des icônes (internationales, avec en toile de fond les velléités de développement local.Processes of identity and historical appropriation, rooted in economic purpose, are today arising in South Africa. A tourism activity, based on authenticity and interaction, becomes particularly popular: the Township tours. It assumes an episode of the country history, i.e. urban segregation, which was given a lot of media coverage. In the meantime, it tries to invert the repulsive image that is commonly associated with apartheid. The attraction for township areas has to be linked to the wish of understanding the institutionalized racial discrimination in South Africa, as well as its pacific end. Paradoxically, the reputation of dangerousness, poverty and informality of those former black urban areas seems to act as a loss leader. Through the example of the province of KwaZulu-Natal, it will be seen that this new socio-tourist activity is now playing a multiculturalism card carried by popular icons, with the local development target in

    The high prevalence of chronic illnesses in South Asian Indian immigrant women underscores the need for identifying factors that could influence their PA. The purpose of this qualitative study was to examine the perspectives of South Asian Indian immigrant women related to barriers to and motives for lifestyle PA within the PA Framework for South Asian Indian Immigrants. Forty women participated in focus groups that were conducted in English and Hindi. Focus group questions were open-ended and semistructured. Transcribed and de-identified audiotaped sessions were coded and analyzed using Atlas.ti software. Role expectation was a core theme for barriers with four subthemes: lack of time, loss of interest, diminished social support, and environmental constraints. Self-motivation was a core theme for motives with three subthemes: optimal physical and psychological health, emphasis on external beauty, and strong social support. Future PA interventions need to target these culturally sensitive factors.

    The production of 231 Pa and of 232 U by irradiating a 230 Th/ 232 Th mixture (containing 12 mol per cent 230 Th) in form of ThO 2 at a thermal neutron flux of 6.9 x 10 13 cm -2 s -1 for 4 months was investigated. Pa, U and Th were separated and the chemical yields were determined. 2.6% of the 230 Th were transformed into 231 Pa and 0.13% into 232 U. These values are higher than those calculated for a thermal flux, but lower than those calculated for a flux ratio epithermal to thermal = 0.03. 231 Pa and 232 U were isolated in form of a protactinium solution and of U 3 O 8 with 94.9 and 89.1% chemical yields, respectively. Foreign activities were not detected. Thorium was recuperated and isolated as ThO 2 , with a chemical yield of 93.6%. (orig.)

    Farnesyltransferase inhibitors (FTIs) radiosensitize tumor cell lines expressing activated H-Ras. K-Ras however remains active after FTI treatment due to prenylation by geranylgeranyltransferase. Up to 90% of pancreatic carcinomas (PaCa) are mutant in K-ras. We hypothesized that combined FTI and geranylgeranyltransferase inhibitor (GGTI) treatment could radiosensitize PaCa cells. Nine human PaCa lines (7 K-ras-mutant, 2 ras-wt) and transgenic mouse pancreatic ductal cells (PDC) expressing wt-ras or mutant K-ras were tested in clonogenic assays with combined FTI-A +/- GGTI-B (Merck and Co Inc.). Inhibition of PI3- kinase (with LY294002) or inhibition of MEK1/2 (with U0126) served to assess the significance of the PI3-kinase and MAPK to radiation survival in these cells. H- and K-Ras prenylation status and changes in phosphorylation of AKT and MAPK were monitored as were changes in cell cycle distribution. FTI+GGTI treatment achieved inhibition of K-Ras prenylation in all PaCa cell lines. This treatment radiosensitized the K-ras mutant cell lines AsPC-1, Capan-2, MiaPaCa-2 and PSN-1, PancM, but not Capan-1 or the ras-wt cell lines (BxPC-3, HS766T, PDC-wt). L-778,123, a dual action inhibitor, sensitized all K-ras mutant cells. Surprisingly, PancM, Panc-1, MiaPaCa-2 and PDC K-Ras cells were radiosensitized by FTI treatment alone. R11577, another FTI without GGTI activity, also sensitized Panc-1 and MiaPaCa-2 and additionally AsPC-1 cells. Radiosensitization was also achieved after treatment with LY294002 in all PaCa lines expressing mutant-K-ras and the ras-wt line BxPC-3 overexpressing Akt2. However these lines were not sensitized by U0126. FTI+GGTI sensitize K-ras mt PaCa cell lines to radiation. PI3-kinase signaling but not MAPK signaling appears to contribute to radiation survival in PaCa cells. Radiosensitization of certain PaCa cells by FTI alone indicates that alternate pathways or farnesylated targets other than K-Ras may also be involved in radiation survival

  14. Synergy of combined tPA-edaravone therapy in experimental thrombotic stroke.

    Directory of Open Access Journals (Sweden)

    Yu-Yo Sun

    Full Text Available Edaravone, a potent antioxidant, may improve thrombolytic therapy because it benefits ischemic stroke patients on its own and mitigates adverse effects of tissue plasminogen activator (tPA in preclinical models. However, whether the combined tPA-edaravone therapy is more effective in reducing infarct size than singular treatment is uncertain. Here we investigated this issue using a transient hypoxia-ischemia (tHI-induced thrombotic stroke model, in which adult C57BL/6 mice were subjected to reversible ligation of the unilateral common carotid artery plus inhalation of 7.5% oxygen for 30 min. While unilateral occlusion of the common carotid artery suppressed cerebral blood flow transiently, the addition of hypoxia triggered reperfusion deficits, endogenous thrombosis, and attenuated tPA activity, leading up to infarction. We compared the outcomes of vehicle-controls, edaravone treatment, tPA treatment at 0.5, 1, or 4 h post-tHI, and combined tPA-edaravone therapies with mortality rate and infarct size as the primary end-points. The best treatment was further compared with vehicle-controls in behavioral, biochemical, and diffusion tensor imaging (DTI analyses. We found that application of tPA at 0.5 or 1 h--but not at 4 h post-tHI--significantly decreased infarct size and showed synergistic (p50% reduction of mortality, ∼ 80% decline in infarct size, and strong white-matter protection. It also improved vascular reperfusion and decreased oxidative stress, inflammatory cytokines, and matrix metalloproteinase activities. In conclusion, edaravone synergizes with acute tPA treatment in experimental thrombotic stroke, suggesting that clinical application of the combined tPA-edaravone therapy merits investigation.

    The in vitro activity of PA-824 and BTZ043 against 30 Nocardia brasiliensis isolates was tested. The MIC(50) and MIC(90) values for PA-824 were both >64 μg/ml. The same values for BTZ043 were 0.125 and 0.250 μg/ml. Given the MIC values for benzothiazinone (BTZ) compounds, we consider them good candidates to be tested in vivo against N. brasiliensis.

    The recessive lethal character Luteus-Pa is found in cacao (Theobroma cacao) genotypes of the Parinari series (Pa) and is characterized by expression of leaf chlorosis and seedling death. Several genotypes of the Pa series are bearers of the gene responsible for the expression of the Luteus-Pa character, which can be used as a tool for determining relationships between genotypes of this group. To evaluate this phenomenon, we analyzed the differential expression of genes between mutant seedlings and wild-type hybrid Pa 30 x 169 seedlings, with the aim of elucidating the possible lethal mechanisms of the homozygous recessive character Luteus-Pa. Plant material was harvested from leaves of wild and mutant seedlings at different periods to construct a subtractive library and perform quantitative analysis using real-time PCR. The 649 sequences obtained from the subtractive library had an average length of 500 bp, forming 409 contigs. The probable proteins encoded were grouped into 10 functional categories. Data from ESTs identified genes associated with Rubisco, peroxidases, and other proteins and enzymes related to carbon assimilation, respiration, and photosystem 2. Mutant seedlings were characterized by synthesizing defective PsbO and PsbA proteins, which were overexpressed from 15 to 20 days after seedling emergence.

    This article provides a comparison between genomic medicine and forensic genetics in Mexico, in light of recent depictions of the nation as a 'país de gordos' (country of the fat) and a 'país de muertos' (country of the dead). We examine the continuities and ruptures in the public image of genetics in these two areas of attention, health and security, focusing especially on how the relevant publics of genetic science are assembled in each case. Publics of biomedical and forensic genetics are assembled through processes of recruitment and interpellation, in ways that modulate current theorizations of co-production. The comparison also provides a vista onto discussions regarding the involvement of genetics in regimes of governance and citizenship and about the relationship between the state and biopower in a context of perceived health crisis and war-like violence.

    An intercomparison between the primary pressure balance of the LNE and a mercury manometer developed at the All-Russian Research Institute for Physical, Technical and Radio-Technical Measurements (VNIIFTRI) for purposes of temperature measurement was undertaken in 1990. A short description of the two standards is given. The transfer standard was a pressure balance equipped with a piston-cylinder assembly that has the same characteristics as the standard of the Laboratoire National d'Essais (LNE). The results obtained from 30 kPa to 110 kPa showed a systematic relative difference of 12 parts in 106 between the two standards. This difference is significant, as the combined relative uncertainty at 1 σ level is estimated to be 4,2 parts in 106. These results are analysed in this paper.

    A study on the oxidation of high density polyethylene (HDPE) by γ ray irradiation in oxygen atmosphere has been made. The influence of irradiated time on the oxidation has been investigated with the help of Fourier Transform Infrared-Photoacoustics Spectroscopy (FTIR-PAS). Results of FTIR-PAS show after irradiation groups like -C=O, -O-C-O-, O=C-O- were introduced into the HDPE. Although the γ ray has powerful penetrability, the oxidation mainly takes place on the surface of HDPE. after 4 h irradiation in oxygen (dose rate 66 Gy/min.), -C=O is the main group which was introduced into the surface of HDPE. Lengthening the irradiation process makes the pre-produced oxidized section in HDPE surface continue their reactions to yield some oxidation products with the structures of -O-C-O-, O=C-O- and so on. FTIR shows there are reactions or week interaction like hydrogen bond between the irradiated HDPE and PA6 in the binary blends, this is helpful to increase the compatibility of the phase of HDPE and polyamide-6 (PA6) in the blend. Scanning Electron Microscope (SEM) result shows that the interface between HDPE matrix and PA6 domains is much clear and smoother in 0γHDPE/PA6 blends than in 4γHDPE/PA6 and 7γHDPE/PA6 blends. These suggested the miscibility of PA6 and HDPE was improved after HDPE irradiating in oxygen by γ ray radiation

    Highlights: • Biodiesel production from esterification of oleic acid was catalyzed by PA/NaY. • The influences of the process operating parameters were studied. • RSM was employed to optimize the experimental conditions. • The kinetic equation of the esterification reaction was investigated. - Abstract: Because of the incitements from increasing petroleum prices, diminishing petroleum reserves and the environmental consequences of exhaust gases from petroleum fueled engines, biodiesel has been used as a substitute of the regular diesel in recent years. In this paper, biodiesel production from the esterification of the free fatty oil oleic acid with ethanol catalyzed by PA/NaY (PA = organic phosphonic acid) was investigated, and the effect of reaction conditions such as PA loading, catalyst amount, molar ratio of alcohol to acid, reaction temperature and reaction time on the esterification reaction was examined. The process optimization using response surface methodology (RSM) was performed and the interactions between the operational variables were elucidated. The optimum values for maximum conversion ratio of oleic acid could be obtained by using a Box–Behnken center-united design with a minimum of experimental work. The oleic acid conversion reached 79.51 ± 0.68% with the molar ratio of alcohol to oleic acid being 7:1 and 1.7 g PA/NaY catalyst (20 ml of PA loading) at 105 °C for 7 h. Moreover, a kinetic model for the esterification catalyzed by PA/NaY catalyst was established. By fitting the kinetic model with the experimental results, the reaction order n = 2, activation energy of the positive reaction Ea + = 43.41 kJ/mol and that of the reverse reaction Ea − = 59.74 kJ/mol were obtained

    In predominantly isiXhosa-speaking township communities in South Africa, men who have sex with men negotiate their identities and sexual practices alongside heteronormative cultural scripts of what it means to be a man. Such idealised notions of masculinity are predicated on the selective appropriation of cultural practices that preserve (heterosexual) male privilege and power. In this paper, we explore the identity work done by men who have sex with men, with particular reference to male circumcision as a cultural practice widely drawn on to inform and regulate normative masculinity. Through a narrative-discursive analysis of the accounts provided by men who have sex with men from township communities, we highlight how participants' dissident sexualities are constructed as compromising their masculine identities. Participating in cultural practices such as traditional circumcision aligns participants to the idealised forms of masculinity that afford men full citizenship in their communities. Study findings suggest that sexual dissidence is less troubling to participants than deviating from gendered markers of hegemonic masculinity, and point to ways in which marginalised men might have an interest in maintaining the dominant gendered order. We conclude with implications for research and programmatic work with gay, bisexual and other men who have sex with men.

    A hyperbaric environment may influence lactate metabolism due to hyperoxia affecting biochemical pathways. The purpose of our study was to determine the blood lactate levels occurring at high workloads in a sample of professional divers under simulated caisson conditions. The ambient air pressure was equivalent to a diving depth of 30 m of seawater (400 kPa). A total of 23 healthy male subjects performed graded bicycle exercise in a dry hyperbaric chamber up to a maximum of 3.5 W kg(-1) body weight at normal (100 kPa) and elevated ambient air pressure (400 kPa). The blood lactate level and the heart rate were measured. In comparison with control conditions, the heart rate and the peripheral blood lactate level were significantly lower at depth for all workloads. The differences between the normobaric and hyperbaric lactate values may be explained by an overall improvement in lactate metabolism at elevated ambient pressure, especially in the working muscles and the organs responsible for the lactate reduction, i.e., the liver. The reduced heart rate may be an effect of the improved tissue oxygen supply at depth.

    Our previously published CUDA-only application PaSWAS for Smith-Waterman (SW) sequence alignment of any type of sequence on NVIDIA-based GPUs is platform-specific and therefore adopted less than could be. The OpenCL language is supported more widely and allows use on a variety of hardware platforms. Moreover, there is a need to promote the adoption of parallel computing in bioinformatics by making its use and extension more simple through more and better application of high-level languages commonly used in bioinformatics, such as Python. The novel application pyPaSWAS presents the parallel SW sequence alignment code fully packed in Python. It is a generic SW implementation running on several hardware platforms with multi-core systems and/or GPUs that provides accurate sequence alignments that also can be inspected for alignment details. Additionally, pyPaSWAS support the affine gap penalty. Python libraries are used for automated system configuration, I/O and logging. This way, the Python environment will stimulate further extension and use of pyPaSWAS. pyPaSWAS presents an easy Python-based environment for accurate and retrievable parallel SW sequence alignments on GPUs and multi-core systems. The strategy of integrating Python with high-performance parallel compute languages to create a developer- and user-friendly environment should be considered for other computationally intensive bioinformatics algorithms.

    The comprehensive in vitro proarrhythmia assay (CiPA) is a nonclinical, mechanism-based paradigm for assessing drug proarrhythmic liability. The first CiPA assay determines effects on cloned human cardiac ion channels. The second investigates whether the latter study-generated metrics engender proarrhythmic markers on a computationally reconstructed human ventricular action potential. The third evaluates conclusions from, and searches possibly missed effects by in silico analysis, in human stem cell-derived cardiomyocytes (hSC-CMs). CiPA ad hoc Expert-Working Groups have proposed patch clamp protocols for seven cardiac ion channels, a modified O'Hara-Rudy model for in silico analysis, detailed procedures for field (MEA) and action potential (VSD) measurements in hSC-CMs, and 29 reference drugs for CiPA assay testing and validation. CiPA adoption as drug development tool for identifying electrophysiological mechanisms conferring proarrhythmic liability to candidate drugs is a complex, multi-functional task requiring significant time, reflection, and efforts to be fully achieved.

    Adhesion of gold on parylene C (Pa-c) is a major hurdle in achieving reliable and durable performance for biosensor application due to the hydrophobicity of Pa-c. It is, therefore, imperative to put efforts to improve adhesion between Au and Pa-c. In this reseach, oxygen plasma treatment for adhesion improvement was performed on Pa-c surfaces at various plasma powers and times. To analyze the relation of surface energy and roughness to adhesion promotion, we used several techniques such as contact-angle, surface-energy, surface-roughness, and adhesion analyses. As the oxygen plasma power and time were increased, the surface roughness of Pa-c increased. Also, Au films had larger and more uniform grain sizes as the oxygen plasma power and time were increased. Untreated surfaces revealed a contact angle of 108 .deg. , but the contact angle drastically decreased in the initial stage of oxygen plasma treatment and slowly decreased with increasing power and time to values of 27.3 and 34, respectively. From the adhesion analysis, adhesion was improved as the plasma power or time was increased. The improvement of adhesion is related to an increase in roughness as well as carbonyl groups.

    Primary hypertension is associated with an impaired capacity for acute release of endothelial tissue-type plasminogen activator (t-PA), which is an important local protective response to prevent thrombus extension. As hypertensive vascular remodeling potentially results in increased vascular wall shear stress, we investigated the impact of shear on regulation of t-PA. Cultured human endothelial cells were exposed to low (≤1.5 dyn/cm 2 ) or high (25 dyn/cm 2 ) laminar shear stress for up to 48 h in two different experimental models. Using real-time RT-PCR and ELISA, shear stress was observed to time and magnitude-dependently suppress t-PA transcript and protein secretion to approximately 30% of basal levels. Mechanistic experiments revealed reduced nuclear protein binding to the t-PA specific CRE element (EMSA) and an almost completely abrogated shear response with pharmacologic JNK inhibition. We conclude that prolonged high laminar shear stress suppresses endothelial t-PA expression and may therefore contribute to the enhanced risk of arterial thrombosis in hypertensive disease.

  16. Aerodynamics of the advanced launch system (ALS) propulsion and avionics (P/A) module

    Ferguson, Stan; Savage, Dick

    1992-01-01

    This paper discusses the design and testing of candidate Advanced Launch System (ALS) Propulsion and Avionics (P/A) Module configurations. The P/A Module is a key element of future launch systems because it is essential to the recovery and reuse of high-value propulsion and avionics hardware. The ALS approach involves landing of first stage (booster) and/or second stage (core) P/A modules near the launch site to minimize logistics and refurbishment cost. The key issue addressed herein is the aerodynamic design of the P/A module, including the stability characteristics and the lift-to-drag (L/D) performance required to achieve the necessary landing guidance accuracy. The reference P/A module configuration was found to be statically stable for the desired flight regime, to provide adequate L/D for targeting, and to have effective modulation of the L/D performance using a body flap. The hypersonic aerodynamic trends for nose corner radius, boattail angle and body flap deflections were consistent with pretest predictions. However, the levels for the L/D and axial force for hypersonic Mach numbers were overpredicted by impact theories.

    Science.gov (United States)

    Meschia, J F

    2000-05-15

    Every patient with acute stroke who presents to a medical center that has appropriate resources should undergo evaluation for intravenous tPA therapy. Such therapy should not be given unless the patient meets strict eligibility criteria based on clinical, radiographic, and laboratory data. Intra-arterial thrombolysis may be a promising alternative to intravenous tPA therapy, but it should still be regarded as experimental. Daily aspirin therapy should be initiated immediately in most patients who do not receive intravenous tPA therapy and after 24 hours in most patients who receive this treatment. Measures should be taken to prevent medical complications, such as aspiration pneumonia, deep vein thrombosis, contractures, and pressure sores. Early initiation of rehabilitation can maximize stroke recovery. Whenever feasible, institutions should have stroke teams or units to streamline care and provide expertise for patients with acute stroke.

  19. Preclinical assessment of adjunctive tPA and DNase for peritoneal dialysis associated peritonitis.

    Directory of Open Access Journals (Sweden)

    Amanda L McGuire

    Full Text Available A major complication of peritoneal dialysis is the development of peritonitis, which is associated with reduced technique and patient survival. The inflammatory response elicited by infection results in a fibrin and debris-rich environment within the peritoneal cavity, which may reduce the effectiveness of antimicrobial agents and predispose to recurrence or relapse of infection. Strategies to enhance responses to antimicrobial agents therefore have the potential to improve patient outcomes. This study presents pre-clinical data describing the compatibility of tPA and DNase in combination with antimicrobial agents used for the treatment of PD peritonitis. tPA and DNase were stable in standard dialysate solution and in the presence of antimicrobial agents, and were safe when given intraperitoneally in a mouse model with no evidence of local or systemic toxicity. Adjunctive tPA and DNase may have a role in the management of patients presenting with PD peritonitis.

    2018-01-01

    In the present study efforts have been made to prepare functional prototypes with improved thermal, mechanical and morphological properties from polymeric waste for sustainability. The primary recycled acrylonitrile butadiene styrene (ABS) and polyamide 6 (PA6) has been selected as matrix material with bio-degradable and bio-compatible banana fibers (BF) as reinforcement. The blend (in form of feed stock filament wire) of ABS/PA6 and BF was prepared in house by conventional twin screw extrusion (TSE) process. Finally feed stock filament of ABS/PA6 reinforced with BF was put to run on open source fused deposition modelling based three dimensional printer (without any change in hardware/software of the system) for printing of functional prototypes with improved thermal/mechanical/morphological properties. The results are supported by photomicrographs, thermographs and mechanical testing.

  1. Blown films of PA6/MMT nanocomposites: structural characterization by SAXs

    Marini, J.; Beatrice, C.A.G.; Lucas, A.A.; Bretas, R.E.S.

    2016-01-01

    In this work the influence of the processing conditions (take up and blow up ratios, TUR and BUR, respectively) in the nano-periodicity and lamellae orientation of PA6 nanocomposites blown films with natural (MMT) and organically modified montmorillonite (oMMT) was studied by SAXS. Unexpectedly, a preferred orientation of the crystalline lamellae along the normal direction (ND) was observed for all analyzed films. Such behavior can be explained by the preservation of the initial lamellae orientation of the PA6 chains imposed by the spiral flow in the die, almost null elastic recovery and fast crystallization kinetics of PA6 at the processing conditions applied. The orientation of the nanoparticles (measured by TEM) showed to be directly dependent on the TUR and BUR. The presence of the reinforcing fillers and the different processing conditions showed no significant influence on the nanoperiodicity. (author)

    Oliveira, Amanda D. de; Pessan, Luiz A.

    2009-01-01

    To achieve a balance between stiffness and toughness, ternary nanocomposites based on blends of polyamide 6 (PA6) and acrylonitrile-butadiene-styrene (ABS) were prepared by the melt intercalation using the organoclay Cloisite R 30B (OMMT) and the styrene-maleic anhydride copolymer (SMA) as compatibilizer. Four blending sequences were used to prepare studied systems and their mechanical properties studied through the Young's modulus and notched Izod impact. It was observed that the materials prepared by all blending sequences studied showed an increase in the Young's modulus compared to the neat PA6. However, a decrease in the toughness was observed for the systems with the addition of the organoclay. The DRX results showed an intercalated structure for the some systems that used ABS in their compositions. HDT measurements of the nanocomposites showed an increase in this property compared to the neat PA6. The use of nanoclay lead to a reinforcement of the polymeric matrix. (author)

    231Pa and 230Th in the ocean are produced at a constant ratio by Uranium decay but adsorption onto particles removes these tracers differentially. This fractionation process makes it possible to use the elemental 231Pa/230Th ratio as a paleoceanography proxy, frequently used for deriving the strength of Atlantic Meridional Overturning Circulation. The removal process, however, is further complicated by the abundance and composition of the available particle types. Understanding how dissolved tracers interact with the particle field in the ocean is key to better understand the biogeochemical cycling of these particle-reactive elements and their use as a flux tracer in present and past oceans. We here present simulations of the 231Pa/230Th ratio using the Transport Matrix Method (TMM, Khatiwala, 2007), focusing especially on the role of the nepheloid layer in controlling the distribution of these radiotracers. The model simulates each tracer separately, with advective-diffusive transport based on the ECCO ocean state estimate (Stammer et al., 2004). Sources include production by Uranium decay and dust dissolution. Radioactive decay and importantly, reversible scavenging and sedimentation are the main sinks that control the removal of the radiotracers. Similar to previous studies, we consider particle fields consisting of calcium carbonate, opal, particle organic matter, and dust. A novelty is that we explicitly consider the influence of an additional bottom particle layer (nepheloid). Simulations that include a nepheloid layer produce vertical profiles that better fit the observed distribution of 230Th and 231Pa. Specifically, observational data in the South Atlantic and eastern South Pacific indicate a mid-depth inflection (for both Pa and Th), a feature that can only be obtained if a nepheloid layer is included in the simulation. Our simulations reinforce the idea that nepheloid layers play an important role in Pa and Th cycling in the ocean (Deng et al., 2014

    Full Text Available BACKGROUND: Regular physical activity has significant benefits for health. For instance, it can reduce the risk of cardiovascular disease, diabetes and osteoporosis, help control weight, and promote psychological well-being. There are many factors that can influence physical activity; socioeconomic status, family, size of place of residence, environmental conditions etc AIM: The aim of the study was to analyze physical activity and inactivity of adult population in the Olomouc region in terms of size of residence, type of housing, body weight status, smoking and participation in organized physical activity. METHODS: 1011 randomly selected residents of the Olomouc region (448 males and 563 females aged 41.14 ± 8.63 years participated in this study. To obtain selected indicators of physical activity, we used the ANEWS questionnaire which was distributed by university students in Spring and Fall periods from 2005 to 2009. For healthy adults aged 18 to 65 years, the goal recommended by the WHO is to achieve a minimum of 30 minutes of moderateintensity physical activity 5 days a week or at least 20 minutes of vigorous-intensity physical activity 3 days a week. RESULTS: The most physically active were males aged 36-45 years. From the selected correlates, those with the highest influence on total weekly PA were the size of residence and type of house. On the other hand, factors that did not affect total weekly PA were smoking, participation in organized PA and body mass index. The most commonly performed type of PA is cycling; followed in males with soccer and tennis and in women with aerobic dance and fitness walking. CONCLUSION: In the Olomouc region there is a need to preserve and develop the conditions to perform PA. Due to the landscape in the Olomouc region and due to the popularity of cycling, we recommend focus on this type of PA.

    2017-06-12

    Additive manufacturing needs a broader selection of materials for part production. In order for the Los Alamos National Laboratory (LANL) to investigate new materials for selective laser sintering (SLS), this paper reviews research on the effect of print parameters on part density, accuracy, and surface roughness of polyamide 12 (PA12, PA2200). The literature review serves to enhance the understanding of how changing the laser powder, scan speed, etc. will affect the mechanical properties of a commercial powder. By doing so, this understanding will help the investigation of new materials for SLS.

    The PaAlr1 gene encoding a putative plasma membrane magnesium (Mg) transporter in Podospora anserina was inactivated. The PaAlr1(Δ) mutants showed sensitivity to deprivation and excess Mg(2+) and Ca(2+). They also exhibited an autonomous ascospore maturation defect. Mutant ascospores were arrested at an early stage when they contained two nuclei. These data emphasize the role of Mg ions during sexual development in a filamentous fungus.

    1995-01-01

    Distribution of Ra-226 and Pa-231 in rock has been studied to find signatures that may be attributed to diffusion. The idea of studying these nuclides originated from the need to obtain interpretative support to the findings of U movement in rock. Concentration profiles of Ra-226 and Pa-231 with other U series nuclides were measured across the secondary U accumulations observed in altered rock close to a fracture in the vicinity of U deposit, and in a radioactivity anomaly.

We examined the effects of two group-based HIV prevention interventions that engaged men and their female partners together in a couples intervention (Couples Health CoOp [CHC] and a gender-separate intervention (Men’s Health CoOp/Women’s Health CoOp [MHC/WHC] on women’s reports of power, communication, and conflict in relationships. Methods: The cluster-randomized field experiment included heterosexual couples from a high-density South African township in which neighborhoods were randomized to one of the intervention arms or a control arm that received the WHC only. Participants completed in-person study visits at baseline and 6-month follow-up. We examined group differences using one-way analysis of variance and multivariable regression models.Results: Of the 290 couples enrolled, 255 women remained in the same partnership over 6 months. Following the intervention, women in the CHC arm compared with those in the WHC arm were more likely to report an increase in relationship control (ß=0.92, 95% confidence interval [CI]: 0.02, 1.83, P=0.045 and gender norms supporting female autonomy in relationships (ß=0.99, 95% CI: 0.07, 1.91, P=0.035.

    2012-08-01

    Transcription pattern during mycelium growth of Podospora anserina was assayed by microarray analysis in wild type and in mutants affected in the MAP kinase genes PaMpk1 and PaMpk2 and in the NADPH oxidase gene PaNox1. 15% of the genes have their expression modified by a factor two or more as growth proceeds in wild type. The genes whose expression is modified during growth in P. anserina are either not conserved or differently regulated in Neurospora crassa and Aspergillus niger, two fungi for which transcriptome data during growth are available. The P. anserina mutants display a similar alteration of their transcriptome profile, with nearly 1000 genes affected similarly in the three mutants, accounting for their similar growth phenotypes. Yet, each mutant has its specific set of modified transcripts, in line with particular phenotypes exhibited by each mutant. Again, there is limited conservation during evolution of the genes regulated at the transcription level by MAP kinases, as indicated by the comparison the P. anserina data, with those of Aspergillus fumigatus and N. crassa, two fungi for which gene expression data are available for mutants of the MAPK pathways. Among the genes regulated in wild type and affected in the mutants, those involved in carbohydrate and secondary metabolisms appear prominent. The vast majority of the genes differentially expressed are of unknown function. Availability of their transcription profile at various stages of development should help to decipher their role in fungal physiology and development. Copyright © 2012 Elsevier Inc.

    1999-01-01

    We describe the procedures for constructing an instrument designed to evaluate children's proficiency in American Sign Language (ASL). The American Sign Language Proficiency Assessment (ASL-PA) is a much-needed tool that potentially could be used by researchers, language specialists, and qualified school personnel. A half-hour ASL sample is collected on video from a target child (between ages 6 and 12) across three separate discourse settings and is later analyzed and scored by an assessor who is highly proficient in ASL. After the child's language sample is scored, he or she can be assigned an ASL proficiency rating of Level 1, 2, or 3. At this phase in its development, substantial evidence of reliability and validity has been obtained for the ASL-PA using a sample of 80 profoundly deaf children (ages 6-12) of varying ASL skill levels. The article first explains the item development and administration of the ASL-PA instrument, then describes the empirical item analysis, standard setting procedures, and evidence of reliability and validity. The ASL-PA is a promising instrument for assessing elementary school-age children's ASL proficiency. Plans for further development are also discussed.

    1987-01-01

    The metabolism of DG, PA and PI were studied in purified rat mast cells to determine whether generally accepted pathways of PI metabolism could explain the pattern of fatty acids seen in these intermediates. A method was developed to separate and quantitate by mass (for DG) or endogenous labeling (for PA and PI) the different molecular species of each lipid that are defined by their component fatty acids. The resultant molecular species fingerprint for each lipid was examined to see if it was similar to other intermediates in the PI cycle. For each class of compounds the percent in a given subclass was recorded. Stimulation caused a reduction of more saturated subclasses and/or an increase in AA containing compounds in PA, PI and DG. The relative similarity of subclasses of 32 P-PA and 32 P-PI supports the view that they are metabolically related. The relative absence of AA-containing species of DG suggests that most of the stimulated increase of DG was not produced by PI hydrolysis

  2. The Effect of Nanoclay on Dust Generation during Drilling of PA6 Nanocomposites

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available During the past decade, polymer nanocomposites have emerged as a novel and rapidly developing class of materials and attracted considerable investment in research and development worldwide. However, there is currently a lack of information available in the literature on the nano and ultrafine particle emission rates from these materials. In this paper, influence of nanoclay on mechanical drilling of PA6 composites, in terms of dust generation, has been reported. With the help of real-time characterization, submicrometer-sized particles (5.6–512 nm, size distribution, and number concentration emitted from polyamide 6/nanoclay composites during mechanical drilling are studied. Total particle concentration for the PA6/nanoclay composites was 20,000 cm−3, while unreinforced panel measured a total concentration of approximately 400,000 cm−3. While the airborne particle concentration for the PA6/nanoclay composites was 20 times lower than for the PA6 matrix, the concentration of deposited nanoparticles doubled for the nanocomposite. The results clearly show that more particles in the size range between 175 and 350 nm are generated, during drilling of the nanocomposites, and these particles deposit in a shorter time. It is likely that the presence of nanoclay in some way retains the formation of high quantity of airborne particles and promotes particle deposition.

    Intravenous alteplase (rt-PA) therapy has been widely approved for acute ischemic stroke. We examined symptomatic intracranial hemorrhage (SICH) and outcomes in older patients treated with rt-PA therapy. We divided 130 consecutive patients treated with rt-PA into two groups: 72 patients younger than 80 years (age <80 group) and 58 patients older than 80 years (age ≥80 group). On CT and MRI scans, SICH was observed in 5 patients (7.1%) in the age <80 group and 4 patients (6.9%) in the age ≥80 group. The SICH rate did not differ significantly between the two groups (odds ratio (OR) 1.21, 95% confidence interval (CI) 0.04-2.39, P=0.6174). The patients in the age ≥80 group had a significantly lower mRS 0-1 rate (8.8 vs. 30.0%; OR 7.20, 95% CI 6.05-8.34, P=0.0009) and significantly higher mRS 6 (mortality) rate (19.3 vs. 9.0%; OR 6.52, 95% CI 5.39-7.65, P=0.0015) compared with those in the age <80 group. These data suggest that the factor of age is not related to SICH but is related to patients' outcomes in rt-PA therapy. (author)

    Highlights: ► KF was modified with caprolactam using toluenediisocyanate (TDI) as bridge. ► Modified KF improves interfacial interaction of iPP/KF/PA6 composites. ► Fiber and nylon 6 inhibited the crystallization of PP continuous phase. -- Abstract: To improve the thermal and mechanical properties of isotactic polypropylene (iPP), iPP/Kevlar fiber (KF)/polyamide 6 (PA6) composites were prepared via the melt-extrusion method on twin-screw extruder. Kevlar fiber was modified with caprolactam using toluenediisocyanate (TDI) as bridge. The microstructure of modified KF was successfully characterized by Fourier transform infrared (FT-IR), X-ray photoelectron spectrometer (XPS) and scanning electron microscopy (SEM), the results showed that KF was bonded with caprolactam and became coarser. Then the modified KF was introduced into iPP, the composites have better mechanical and thermal properties, implying that modification of KF was helpful to improve the interfacial interaction of iPP/KF/PA6 composites. Besides, the crystallization curves indicated that crystallization behavior of PA6 in the composites was homogeneous and fractional. Furthermore, compatibilizer content played an important role in the mechanical and thermal properties of composites.

    In Japan, the intravenous tissue plasminogen activator (t-PA) Alteplase (0.6 mg/kg) administration of the within 3 h of the onset of acute ischemic stroke was approved for therapeutic use in the year 2006. t-PA induces thrombolysis in patients with acute ischemic stroke, and this method has gradually gained recognition among physicians and the general population. However, the number of patients who were treated using Alteplase is low (4,000-5,000 patients/year), and this figure accounts for only 2-3% of the annual number of cases of ischemic stroke. There is little doubt that Alteplase treatment is a potentially effective modality for some patients with acute ischemic stroke. The post-marketing surveillance of 4,749 Japanese patients treated using Alteplase showed that 33% of the patients had modified Rankin scale (mRS) scores of 0-1, 17% of patients died and 4.5% presented with symptomatic intracerebral hemorrhage (ICH); these results were comparable to those from other countries. The expansion of the therapeutic time window has been a matter of concern. The investigators of the European Cooperative Acute Stroke Study (ECASS) have reported that there was significant improvement in the clinical outcomes of patients with acute ischemie stroke when Alteplase was administered 3-4.5 h after the onset of the symptoms. Mismatches in perfusion- and diffusion-weighted (DW) magnetic resonance imaging (MRI) images have been used for selecting patients 3 h after the onset of symptoms, and the findings from MRI, dwimages (DWI) and MR angiography are practical predictors of t-PA therapy within 3 h of onset. The Middle Cerebral Artery Embolism Local Fibrinolytic Intervention Trial (MELT) Japan study showed that local intra-arterial fibrinolysis is effective in patients with embolic MCA occlusion within 6 h of the onset of symptoms. Combining the initiation of intravenous t-PA administration with further intra-arterial fibrinolysis or mechanical thrombolectomy may improve the

  11. The Canadian Precipitation Analysis (CaPA): Evaluation of the statistical interpolation scheme

    2013-04-01

    CaPA (Canadian Precipitation Analysis) is a data assimilation system which employs statistical interpolation to combine observed precipitation with gridded precipitation fields produced by Environment Canada's Global Environmental Multiscale (GEM) climate model into a final gridded precipitation analysis. Precipitation is important in many fields and applications, including agricultural water management projects, flood control programs, and hydroelectric power generation planning. Precipitation is a key input to hydrological models, and there is a desire to have access to the best available information about precipitation in time and space. The principal goal of CaPA is to produce this type of information. In order to perform the necessary statistical interpolation, CaPA requires the estimation of a semi-variogram. This semi-variogram is used to describe the spatial correlations between precipitation innovations, defined as the observed precipitation amounts minus the GEM forecasted amounts predicted at the observation locations. Currently, CaPA uses a single isotropic variogram across the entire analysis domain. The present project investigates the implications of this choice by first conducting a basic variographic analysis of precipitation innovation data across the Canadian prairies, with specific interest in identifying and quantifying potential anisotropy within the domain. This focus is further expanded by identifying the effect of storm type on the variogram. The ultimate goal of the variographic analysis is to develop improved semi-variograms for CaPA that better capture the spatial complexities of precipitation over the Canadian prairies. CaPA presently applies a Box-Cox data transformation to both the observations and the GEM data, prior to the calculation of the innovations. The data transformation is necessary to satisfy the normal distribution assumption, but introduces a significant bias. The second part of the investigation aims at devising a bias

    The proliferation protection levels of MOX-fuel containing small additions of protactinium are evaluated for equilibrium closed and open cycles of a light-water reactor (LWR).Analysis of the ways to the proliferation protection of MOX-fuel by small {sup 231}Pa addition and comparison of this way with another options for giving MOX-fuel the proliferation self-protection property enable us to make the 3 following conclusions: -1) Unique nature of protactinium as a small addition to MOX-fuel is determined by the following properties: - Protactinium is available in the nature (uranium ore) as a long-lived mono-isotope {sup 231}Pa, - under neutron irradiation, {sup 231}Pa is converted into {sup 232}U, which is a long-term source of high energy gamma-radiation and practically non-separable from main fuel mass, - essentially, {sup 231}Pa is a high-quality burnable neutron absorber. -2) From the proliferation self-protection point of view, nuclear fuel cycle closure with fuel recycle is a preferable option because, under this condition, introduction of protactinium into MOX-fuel allows to create the inherent radiation barrier which is in action during full cycle of fuel management at the level corresponding to the accepted today criterion of the Spent Fuel Standard (SFS). In particular, the considered example of multiple MOX-fuel recycle with small addition of {sup 231}Pa (0.2% HM) at each cycle demonstrates a possibility to reach the proliferation protection level of fresh MOX-fuel corresponding to once irradiated fuel with the same cooling time. In this case, the lethal dose (at 30 cm distance from fuel assembly) is received within the minute range. -3) Introduction of {sup 231}Pa into MOX-fuel composition in amount of 0.5% HM allows to prolong action of the SFS from 100 to 200 years. If {sup 231}Pa content is increased up to 5% HM, then MOX-fuel conserves the proliferation self-protection property in respect to short-term unauthorized actions for 200-year period of its

    Full Text Available De acordo com o Banco Mundial, desde o final dos anos 2000 o movimento de aquisição de terras por estrangeiros tem se acentuado nos países em desenvolvimento, impulsionado pelo boom dos preços das commodities. Em termos teóricos, a abordagem da Nova Economia Institucional (NEI argumenta que as instituições são importantes para as estratégias dos agentes econômicos e seu desempenho. Neste estudo, apoiado na NEI, pretende-se responder como as instituições presentes em países periféricos refletem o processo de aquisições de terras por investidores estrangeiros. Para esse objetivo, foram utilizados dados secundários de organizações internacionais, como Food and Agriculture Organization, Banco Mundial, Conferência das Nações Unidas sobre Comércio e Desenvolvimento, Fundo Monetário Internacional, Organização para a Cooperação Econômica e Desenvolvimento Econômico, Wall Street Journal e agências nacionais. A hipótese principal é que a força ou a fraqueza presente no ambiente institucional em países em desenvolvimento tem influência relevante no nível de Investimento Estrangeiro Direto (IED.

    Pavement cells (PCs) are the most frequently occurring cell type in the leaf epidermis and play important roles in leaf growth and function. In many plant species, PCs form highly complex jigsaw-puzzle-shaped cells with interlocking lobes. Understanding of their development is of high interest for plant science research because of their importance for leaf growth and hence for plant fitness and crop yield. Studies of PC development, however, are limited, because robust methods are lacking that enable automatic segmentation and quantification of PC shape parameters suitable to reflect their cellular complexity. Here, we present our new ImageJ-based tool, PaCeQuant, which provides a fully automatic image analysis workflow for PC shape quantification. PaCeQuant automatically detects cell boundaries of PCs from confocal input images and enables manual correction of automatic segmentation results or direct import of manually segmented cells. PaCeQuant simultaneously extracts 27 shape features that include global, contour-based, skeleton-based, and PC-specific object descriptors. In addition, we included a method for classification and analysis of lobes at two-cell junctions and three-cell junctions, respectively. We provide an R script for graphical visualization and statistical analysis. We validated PaCeQuant by extensive comparative analysis to manual segmentation and existing quantification tools and demonstrated its usability to analyze PC shape characteristics during development and between different genotypes. PaCeQuant thus provides a platform for robust, efficient, and reproducible quantitative analysis of PC shape characteristics that can easily be applied to study PC development in large data sets. © 2017 American Society of Plant Biologists.

    Graphene oxide (GO) was prepared by oxidation of graphite flakes by a mixture of H{sub 2}SO{sub 4}/H{sub 3}PO{sub 4} and KMnO{sub 4} based on Marcano's method. Two different masterbatches containing GO (33.3%) and polyamide-6 (PA6) (66.7%) were prepared both via solvent casting in formic acid and by melt mixing in a mini-extruder (Haake). The two masterbatches were then used to prepare PA6-based nanocomposites with a content of 2% in GO. For comparison, a nanocomposite by direct mixing of PA6 and GO (2%) and PA6/graphite nanocomposites were prepared, too. The oxidation of graphite into GO was assessed by X-ray diffraction (XRD), Micro-Raman spectroscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) analyses. All these techniques demonstrated the effectiveness of the graphite modification, since the results put into evidence that, after the acid treatment, interlayer distance, oxygen content and defects increased. SEM micrographs carried out on the nanocomposites, showed GO layers totally surrounded by polyamide-6, this feature is likely due to the strong interaction between the hydrophilic moieties located both on GO and on PA6. On the contrary, no interactions were observed when graphite was used as filler. Mechanical characterization, carried out by tensile and dynamic-mechanical tests, marked an improvement of the mechanical properties observed. Photoluminescence and EPR measurements were carried out onto nanoparticles and nanocomposites to study the nature of the interactions and to assess the possibility to use this class of materials as semiconductors or optical sensors.

    INS/NUPEC presents one of Public acceptance (PA) methods for nuclear power in Japan, 'PA activity by using Nuclear Power Plant Safety Demonstration and Analysis', by using one of videos which is explained and analyzed accident events (Loss of Coolant Accident). Safety regulations of The National Government are strictly implemented in licensing at each of basic design and detailed design. To support safety regulation activities conducted by the National Government, INS/NLTPEC continuously implement Safety demonstration and analysis. With safety demonstration and analysis, made by assuming some abnormal conditions, what impacts could be produced by the assumed conditions are forecast based on specific design data on a given nuclear power plants. When analysis results compared with relevant decision criteria, the safety of nuclear power plants is confirmed. The decision criteria are designed to help judge if or not safety design of nuclear power plants is properly made. The decision criteria are set in the safety examination guidelines by taking sufficient safety allowance based on the latest technical knowledge obtained from a wide range of tests and safety studies. Safety demonstration and analysis is made by taking the procedure which are summarized in this presentation. In Japan, various PA (Public Acceptance) pamphlets and videos on nuclear energy have been published. But many of them focused on such topics as necessity or importance of nuclear energy, basic principles of nuclear power generation, etc., and a few described safety evaluation particularly of abnormal and accident events in accordance with the regulatory requirements. In this background, INS/NUPEC has been making efforts to prepare PA pamphlets and videos to explain the safety of nuclear power plants, to be simple and concrete enough, using various analytical computations for abnormal and accident events. In results, PA activity of INS/NUPEC is evaluated highly by the people

    The transformation of primary care (PC) training sites into patient-centered medical homes (PCMH) has implications for the education of health professionals. This study investigates the extent to which physician assistant (PA) students report learning about the PCMH model and how clinical exposure to PCMH might impact their interest in a primary care career. An electronic survey was distributed to second-year PA students who had recently completed their PC rotation from 12 PA programs. Descriptive statistics and ordered logistic regression analyses were used to characterize the results. A total of 202 second-year PA students completed the survey. When asked about their knowledge of the new health care delivery models, 30% of the students responded they had received instruction about the PCMH. Twenty- five percent of respondents stated they were oriented to new payment structures proposed in the Affordable Care Act and quality improvement principles. Based on their experiences in the primary care clerkship, 64% stated they were likely to pursue a career in primary care, 13% were not likely, and 23% were unsure. Predictors of interest in a primary care career included: (1) age greater than 35 years, (2) being a recipient of a NHSC scholarship, (3) clerkship site setting in an urban cluster of 2,500 to 50,000 people, (4) number of PCMH elements offered at site, and (4) positive impression of team-based care. PA students lack adequate instruction related to the new health care delivery models. Students whose clerkship sites offered greater number of PCMH elements were more interested in pursuing a career in primary care.

  20. Influence of intense scavenging on Pa-Th fractionation in the wake of Kerguelen Island (Southern Ocean)

    Dissolved and particulate excess 230 Th and 231 Pa concentrations (noted 230 Th xs and 231 Pa xs respectively) and 231 Pa xs / 230 Th xs activity ratios were investigated on and out of the Kerguelen plateau (Southern Ocean) in the framework of the Kerguelen Ocean and Plateau compared Study project in order to better understand the influence of particle flux and particle chemistry and advection on the scavenging of 231 Pa. In the wake of Kerguelen, particulate 231 Pa xs is relatively abundant compared to its content in the dissolved phase. This, together with the low fractionation observed between 230 Th and 231 Pa (F Th/Pa ranging from 0.06 ± 0.01 to 1.6 ± 0.2) reflects the domination of the biogenic silica in the particle pool. Along the eastern escarpment of the Kerguelen plateau, the strong 231 Pa xs horizontal gradient in the deep waters highlights the intense removal of 231 Pa at depth, as already observed for 230 Th xs . This local boundary scavenging was attributed to re-suspension of opal-rich particles by nepheloid layers, resulting in fractionation factors F Th/Pa ≤ 1 along the Kerguelen plateau slope. Therefore, both the composition (biogenic opal) and the flux (intense along the margin) of particles control the scavenging of the two radionuclides in the Kerguelen wake. The modelling of 231 Pa distribution with an advection-scavenging model demonstrates that lateral advection of open ocean water on the Kerguelen plateau could supply most of the 231 Pa, which is then efficiently scavenged on the highly productive plateau, as previously proposed for 230 Th xs . It stresses that lateral advection can play a significant role in the overall budget of particle reactive trace elements in a coastal-open ocean system. (authors)

    For over 40 years the US Department of Energy (DOE) and its predecessors have made Californium-252 ( 252 Cf) available for a wide range of industries including medical, nuclear fuels, mining, military and national security. The Radiochemical Engineering Development Center (REDC) located within the Oak Ridge National Laboratory (ORNL) processes irradiated production targets from the High Flux Isotope Reactor (HFIR). Operations in Building 7930, Cell G provide over 70% of the world's demand for 252 Cf. Building 7930 was constructed and equipped in the mid-1960s. Current operations for 252 Cf processing in Building 7930, Cell G require use of through-the-wall manipulators and the PaR Remote Handling System. Maintenance and repairs for the manipulators is readily accomplished by removal of the manipulator and relocation to a repair shop where hands-on work can be performed in glove boxes. Contamination inside cell G does not currently allow manned entry and no provisions were created for a maintenance area inside the cell. There has been no maintenance of the PaR system or upgrades, leaving operations vulnerable should the system have a catastrophic failure. The Cell G PaR system is currently being operated in a run to failure mode. As the manipulator is now 40+ years old there is significant risk in this method of operation. In 2006 an assessment was completed that resulted in recommendations for replacing the manipulator operator control and power centers which are used to control and power the PaR manipulator in Cell G. In mid-2008 the chain for the bridge drive failed and subsequent examinations indicated several damaged links (see Figure 1). To continue operations the PaR manipulator arm is being used to push and pull the bridge as a workaround. A retrieval tool was fabricated, tested and staged inside Cell G that will allow positioning of the bridge and manipulator arm for removal from the cell should the PaR system completely fail.

    Full text of publication follows. The ARRONAX cyclotron [Ref.1], acronym for 'Accelerator for Research in Radiochemistry and Oncology at Nantes Atlantique' is a new facility installed in Nantes, France. A dedicated program has been launched on production of innovative radionuclides for PET imaging and for β- and α- targeted radiotherapy using proton or α particle. Since the accelerator is also able to deliver deuteron beams up to 35 MeV, we have reconsidered the possibility to use them to produce medical isotopes. In this study, we have focused on cross section measurements using the stacked-foil technique [Ref. 2] of one isotope dedicated to alpha radio-immunotherapy (α RIT) [Ref.3], 226 Th which can be produced through different routes. It's of great interest since it has been found to be a more potent alpha particle emitter for leukemia therapies than Bi 213 [Ref.4]. Indeed, the 226 Th decay produced a cascade of four α particles with a cumulated energy of 27.7 MeV. An additional interest is the possible use of a radionuclide generator system 230 U/ 226 Th. 230 U could be produced directly via 231 Pa(p, 2n) 230 U, and indirectly via 230 Pa using proton or deuteron beams through 232 Th(p, 3n) 230 Pa → 230 U, 232 Th(d, 4n) 230 Pa → 230 U. Twelve data sets are published concerning the 230 Pa cross section induced by proton [Ref 5], only one by deuteron [Ref.6]. As sometimes deuteron induced reaction gives higher cross section values, it seems interesting to focus our study on their use as projectile on 232 Th target to produce 230 Pa. Contaminants created during irradiation are also measured since a good optimization of the process is supposed to find the best compromise between production yield and purity of the final product. Our new sets of data are compared with the existing data [Refs.5,6] on other existing production routes and with results given by TALYS code calculations [Ref.7]. References: 1] F.

    In this article, a new approach to study the compatibilization effect of organophilic clays in PA6/PP polymer blends through experimental results of mechanical tests is presented. This study focus on the description of the interphase in compatibilization by addition of the organoclays C15A and C30B into the polymer PA6/PP blend by melt compounding using a Twin Screw Extruder. The experimental results variations are studied, by addition of the organoclays in uncompatibilized polymer blend, using non-parametric analysis of variance (Kruskal-Wallis Test). For all the experimental results, significant differences are identified between the types of polymer blends. It was observed the compatibilization effect of both organophilic clays, being the differences most evident in the presence of PP modified.

    We review the state-of-the-art of Glauber-inspired models for estimating the distribution of the number of participating nucleons in pA and AA collisions. We argue that there is room for improvement in these model when it comes to the treatment of diffractive excitation processes, and present a new simple Glauber-like model where these processes are better taken into account. We also suggest a new way of using the number of participating, or wounded, nucleons to extrapolate event characteristics from pp collisions, and hence get an estimate of basic hadronic final-state properties in pA collisions, which may be used to extract possible nuclear effects. The new method is inspired by the Fritiof model, but based on the full, semi-hard multiparton interaction model of PYTHIA8.

    A dedicated program has been launched on production of innovative radionuclides for PET imaging and for β- and α targeted radiotherapy using proton or α particles at the ARRONAX cyclotron. Since the accelerator is also able to deliver deuteron beams up to 35 MeV, we have reconsidered the possibility of using them to produce medical isotopes. Two isotopes dedicated to targeted therapy have been considered: 226Th, a decay product of 230Pa, and 186Re. The production cross sections of 230Pa and 186Re, as well as those of the contaminants created during the irradiation, have been determined by the stacked-foil technique using deuteron beams. Experimental values have been quantified using a referenced cross section. The measured cross sections have been used to determine expected production yields and compared with the calculated values obtained using the Talys code with default parameters.

    Keitel, Wendy A

    2006-08-01

    Recent terrorist attacks involving the use of Bacillus anthracis spores have stimulated interest in the development of new vaccines for anthrax prevention. Studies of the pathogenesis of anthrax and of the immune responses following infection and immunization underscore the pivotal role that antibodies to the protective antigen play in protection. The most promising vaccine candidates contain purified recombinant protective antigen. Clinical trials of one of these, recombinant protective antigen (rPA)102, are underway. Initial results suggest that rPA102 is well tolerated and immunogenic. Additional trials are necessary to identify optimal formulations and immunization regimens for pre- and postexposure prophylaxis. Future licensure of these and other candidate vaccines will depend on their safety and immunogenicity profiles in humans, and their ability to confer protection in animal models of inhalational anthrax.

    To construct a lentiviral-vector-mediated CyPA small interference RNA (siRNA) and study its function in non-small cell lung cancer. First, four target sequences were selected according to CyPA mRNA sequence, the complementary DNA contained both sense and antisense oligonucleotides were designed, synthesized and cloned into the pGCL-GFP vector, which contained U6 promoter and green fluorescent protein (GFP). The resulting lentiviral vector containing CyPA shRNA was named Lv-shCyPA, and it was confirmed by PCR and sequencing. Next, it was cotransfected by Lipofectamine 2000 along with pHelper1.0 and pHelper 2.0 into 293T cells to package lentivirus particles. At the same time, the packed virus infected non-small cell lung cancer cell (A549), the level of CyPA protein at 5 d after infection was detected by Western Blot to screen the target of CyPA. A549 were infected with Lv-shCyPA and grown as xenografts in severe combined immunodeficient mice. Cell cycle and apoptosis were measured by FCM. It was confirmed by PCR and DNA sequencing that lentiviral-vector-mediated CyPA siRNA (Lv-shCyPA) producing CyPA shRNA was constructed successfully. The titer of concentrated virus were 1 x 10(7) TU/ml. Flow cytometric analysis demonstrated G2-M phase (11.40% +/- 0.68%) was decreased relatively in A549/LvshCyPA compared with control groups (14.52% +/- 1.19%) (Ppathways may lead to new targeted therapies for non-small cell lung cancer.

  15. Expression and biological activity of the cystine knot bioinsecticide PA1b (Pea Albumin 1 Subunit b.

    Directory of Open Access Journals (Sweden)

    Vanessa Eyraud

    Full Text Available The PA1b (Pea Albumin 1, subunit b peptide is an entomotoxin extract from Legume seeds with lethal activity on several insect pests, such as mosquitoes, some aphids and cereal weevils. This 37 amino-acid cysteine-rich peptide has been, until now, obtained by biochemical purification or chemical synthesis. In this paper, we present our results for the transient production of the peptide in Nicotiana benthamiana by agro-infiltration, with a yield of about 35 µg/g of fresh leaves and maximum production 8 days after infiltration. PA1b is part of the PA1 gene which, after post-translational modifications, encodes two peptides (PA1b and PA1a. We show that transforming tobacco with the PA1b cDNA alone does not result in production of the toxin and, in fact, the entire cDNA is necessary, raising the question of the role of PA1a. We constructed a PA1-cassette, allowing for the quick "cut/paste" of different PA1b mutants within a conserved PA1 cDNA. This cassette enabled us to produce the six isoforms of PA1b which exist in pea seeds. Biological tests revealed that all the isoforms display similar activity, with the exception of one which is inactive. The lack of activity in this isoform led us to conclude that the amphiphilic nature of the peptide is necessary for activity. The possible applications of this expression system for other cysteine-rich biomolecules are discussed.

  16. Heavy quarkonium production: Nontrivial transition from pA to AA collisions

    Two novel QCD effects, double-color filtering and mutual boosting of the saturation scales in colliding nuclei, affect the transparency of the nuclei for quark dipoles in comparison with proton-nucleus collisions. The former effect increases the survival probability of the dipoles, since color filtering in one nucleus makes the other one more transparent. The second effect acts in the opposite direction and is stronger; it makes the colliding nuclei more opaque than in the case of pA collisions. As a result of parton saturation in nuclei the effective scale is shifted upward, which leads to an increase of the gluon density at small x. This in turn leads to a stronger transverse momentum broadening in AA compared with pA collisions, i.e., to an additional growth of the saturation momentum. Such a mutual boosting leads to a system of reciprocity equations, which result in a saturation scale, a few times higher in AA than in pA collisions at the energies of the large hadron collider (LHC). Since the dipole cross section is proportional to the saturation momentum squared, the nuclei become much more opaque for dipoles in AA than in pA collisions. For the same reason gluon shadowing turns out to be boosted to a larger magnitude compared with the product of the gluon shadowing factors in each of the colliding nuclei. All these effects make it more difficult to establish a baseline for anomalous J/Ψ suppression in heavy ion collisions at high energies.

    Highlights: ► High shear rate processing was found to greatly impact PA12/starch blend morphologies. ► The morphology was observed to be stable under subsequent processing conditions. ► The mechanical properties of the blends under high-shear rate were greatly improved. ► Polymer blend preparation via high-shear processing has proved to be very effective. ► Finally, polymer blends with improved mechanical properties were obtained. - Abstract: PA12/plasticized starch blends (PA12/TPS) were prepared by high-shear twin screw extruder. The morphology development and the mechanical properties of the blends were investigated as a function of the apparent shear rate. High-shear processing has proved to be an efficient method to finely disperse thermoplastic starch in polyamide 12 matrix. Blends containing TPS domains with a size at the nano-scale (R n ∼ 150 nm) homogeneously dispersed in PA12 matrix were obtained. From a modeling point of view, the variation of the droplet radius is closer to the Wu's predictions compared to the Serpe's predictions. From the basic hypothesis of these models, it can be then assumed that compatibilization between both phases occurs during the blend processing. Furthermore, this morphology of the blends has been proved to be stable after a reprocessing step in an internal mixer most likely due to either strong hydrogen bonds between the hydroxyl groups of starch and amide groups of polyamide 12 or to potentially cross reactions between macroradicals accounting for in situ formation of graft copolymers with the potential function of compatibilizers. Mechanical properties of the blends were found to be strongly dependent on the shear rate parameter of blend processing as the mechanical properties increase with shear rate. In agreement to the blend morphology, the elongation at break of the blends was greatly improved attesting of a good adhesion between both phases.

    Since 2001, Hyalomatrix PA (Fidia Advanced Biopolymers, Abano Terme, Italy) has been used in our center on pediatric burned patients as a temporary dermal substitute to cover deep partial-thickness burns after dermabrasion. This "bridge" treatment was adopted to remove necrotic debris (dermabrasion) and to stimulate regeneration in a humid and protected environment (Hyalomatrix PA). We present results obtained with this approach. On the third to fifth day after admission, dermabrasion was practiced on deep burned areas, which were covered with Hyalomatrix PA. Change of dressings was performed every 7 days. On day 21, those areas still without signs of recovery were removed with classic escharectomy and covered with thin skin grafts. We treated 300 patients. Sixty-one percent needed only one dermabrasion treatment, 22.3% (67 patients) more than one, and 16.7% (50 patients) the classic escharectomy. A total of 83% of patients healed within 21 days. Our study suggests that the combination of dermabrasion with a temporary dermal substitute could be a good and feasible approach for treatment of deep partial-thickness burns. Prospective randomized studies are now necessary to compare our protocol with the gold standard treatment of topical dressings.

    Full Text Available The aim of this pilot study was to characterize seasonal variation in the moderate to vigorous physical activity (MVPA and sedentary behavior of Portuguese school youth, and understand the influence of activity choices and settings. The participants in this study were 24 students, aged 10-13 years. Accelerometers measured daily PA over 7 consecutive days, in different seasons May - June and January - February. In summer, boys accumulated more minutes in MVPA (928 minutes/week than girls (793 minutes/week. In winter the pattern was reversed with girls accumulating more activity than boys (736 minutes/week vs. 598 minutes/week. The repeated measures ANOVA revealed significant effects for season (F = 5.98, p = 0.023 and in- school vs. out-of-school (F = 6.53, p = 0.018. Youth were more active in the summer and activity levels were higher after school than in school. Summer season provided relevant contexts for youth physical activity accumulation. Winter season may have been a significant barrier to boy's preferred PA context. Differences in choices of outdoor or indoor PA, after school, explained the gender differences in seasonal activity patterns

    Evolution of the Norwood procedure has culminated in there currently being three treatment strategies available for initial management: the 'classical' Norwood (utilizing a Blalock-Taussig shunt), the Norwood with right-ventricle to pulmonary artery (RV-PA) conduit, and the 'hybrid' Norwood procedure utilizing bilateral pulmonary artery banding and ductal stenting. Each variant has its potential advantages and disadvantages, and this paper looks to examine the evidence in favor of each strategy, with emphasis on the supportive data for the RV-PA conduit. The 'classical' procedure has the benefit of the greatest accumulated surgical experience and avoids any incision into the ventricle. However, the diastolic run-off of the Blalock-Taussig shunt can cause hemodynamic instability and unpredictable coronary steal phenomenon. The RV-PA conduit has the advantage of maintaining diastolic pressure with a more stable postoperative course, but at the cost of a ventriculotomy that may have detrimental long-term sequelae. The 'hybrid' procedure has the advantage of avoiding cardiopulmonary bypass, but does not always secure coronary blood flow and has a high inter-stage morbidity and reintervention rate. The evidence shows that each technique may have its place in future management, and that treatment algorithms could emerge that direct the choice of procedure for specific patient groups.

    The landslide is a kind of complicated phenomenon with nonlinear inter-reaction. The traditional theories and methods are difficult to study the uncertainty characteristics of dynamic evolution of the landslides. This paper applies box-counting and P-A model to study the fractal characteristics of geometric shape and spatial distribution of the landslide hazards in the study area from Badong county to Zigui county in TGP reservoir region. The data obtained from the study area shows power-law distributions of geometric shape and spatial distribution of the landslides, and thus reveals some fractal or self-similarity properties. The fractral dimensions DAP of the spatial distribution of landslides by P-A model shows that DAP of the western landslides in the study area are smaller than those of the east, which shows that the geometry of the eastern landslide is more irregular and complicated than the western ones. The results show box-counting model and P-A model can be used to characterize the fractal characteristics of geometric shape and spatial distribution of the landslides.

    While considering the geological disposal of radioactive wastes, the behaviour of the radionuclide Np and its daughter element Pa was investigated in the presence of a mixture of anaerobic bacteria (MAB). Originally, MAB were used for the treatment of pulp and paper wastewater. The interaction between radionuclides and bacteria was evaluated by determining distribution coefficients (K d ) over 10 days and at 5 deg. C and 35 deg. C. K d for Np at 35 deg. C after 5 days had a low value around 10 -2 . After 10 days, however, K d was >100-fold higher. On the other hand, K d at 5 deg. C was low (10 -2 ) throughout, without any significant increase over time. The interaction between Pa and MAB was found to be stronger than that for Np, with K d for Pa about 100 times higher. The K d was controlled by some basic factors; the activity of MAB, the complexing capacity of MAB, and the chemical conditions in the solution such as pH and Eh

    A single-dosimeter worn on the anterior surface of the body of a worker was found to significantly underestimate the effective dose to the worker when the radiation comes from the back. Several researchers suggested that this sort of underestimation can be corrected to a certain extent by using an extra dosimeter on the back. However, use of multiple dosimeters also has disadvantages such as complication in control or incurrence of extra cost. Instead of the common multi-dosimeter approach, in this study, a single dosimeter introducing asymmetric filters which enabled to identify PA exposure was designed, and its dose evaluation algorithm for AP-PA mixed radiation fields was established. A prototype TL personal dosimeter was designed and constructed. The Monte Carlo simulations were utilized in the design process and verified by experiments. The dosimeter and algorithm were applicable to photon radiation having an effective energy beyond 100 keV in AP-PA mixed radiation fields. A simplified performance test based on ANSI N13.11 showed satisfactory results. Considering that the requirements of the International Electrotechnical Commission (IEC) and the American National Standards Institute (ANSI) with regard to the dosimeter on angular dependency is reinforced, the dosimeter and the dose evaluation algorithm developed in this study provides a useful approach in practical personal dosimetry against inhomogeneous high energy radiation fields.

    Melatonin is well known for its cardioprotective effects; however, whether melatonin exerts therapeutic effects on cardiomyocyte hypertrophy remains to be investigated, as do the mechanisms underlying these effects, if they exist. Cyclophilin A (CyPA) and its corresponding receptor, CD147, which exists in a variety of cells, play crucial roles in modulating reactive oxygen species (ROS) production. In this study, we explored the role of the CyPA/CD147 signaling pathway in angiotensin II (Ang II)-induced cardiomyocyte hypertrophy and the protective effects exerted by melatonin against Ang II-induced injury in cultured H9C2 cells. Cyclosporine A, a specific CyPA/CD147 signaling pathway inhibitor, was used to manipulate CyPA/CD147 activity. H9C2 cells were then subjected to Ang II or CyPA treatment in either the absence or presence of melatonin. Our results indicate that Ang II induces cardiomyocyte hypertrophy through the CyPA/CD147 signaling pathway and promotes ROS production, which can be blocked by melatonin pretreatment in a concentration-dependent manner, in cultured H9C2 cells and that CyPA/CD147 signaling pathway inhibition protects against Ang II-induced cardiomyocyte hypertrophy. The protective effects of melatonin against Ang II-induced cardiomyocyte hypertrophy depend at least partially on CyPA/CD147 inhibition.

    This study aimed to explore the associations among psychological correlates and physical activity (PA) in Chinese children and to further examine whether these associations varied by different PA measures. PA self-efficacy, motivation, and preference were reported in 449 8-13-year-old Chinese children (252 males). Moderate- to vigorous- intensity PA (MVPA) was measured by the Physical Activity Questionnaire for Older Children (PAQ-C) and with an ActiGraph GT3X accelerometer. Correlations and hierarchical regressions were performed to explore their associations. The study psychological variables were all positively related to PAQ-C and objective MVPA ( r : 0.22-0.63). The associations with PAQ-C were all substantially stronger than those with accelerometry. Beyond the explained variance accounted for by demographics and social desirability, the addition of the psychological correlates accounted for 45% of the variance of the PAQ-C score, while only 13% for accelerometry-based MVPA. The associations of specific variables with the PAQ-C score (age, PA self-efficacy, autonomous motivation and preference) were somewhat different from those associated with objective MVPA (PA self-efficacy, autonomous motivation, and negatively associated with female gender). This study demonstrated the importance of self-efficacy and autonomous motivation in association with PA and indicated the difference in level of their associations with different PA measures.

    hADSCs transplantation in cirrhosis models improves liver function and reduces fibrosis. In addition, Ad-huPA gene therapy diminished fibrosis and increased hepatocyte regeneration. In this study, we evaluate the combination of these therapies in an advanced liver fibrosis experimental model. hADSCs were expanded and characterized before transplantation. Ad-huPA was simultaneously administrated via the ileac vein. Animals were immunosuppressed by CsA 24 h before treatment and until sacrifice at 10 days post-treatment. huPA liver expression and hADSCs biodistribution were evaluated, as well as the percentage of fibrotic tissue, hepatic mRNA levels of Col-αI, TGF-β1, CTGF, α-SMA, PAI-I, MMP2 and serum levels of ALT, AST and albumin. hADSCs homed mainly in liver, whereas huPA expression was similar in Ad-huPA and hADSCs/Ad-huPA groups. hADSCs, Ad-huPA and hADSCs/Ad-huPA treatment improves albumin levels, reduces liver fibrosis and diminishes Collagen α1, CTGF and α-SMA mRNA liver levels. ALT and AST serum levels showed a significant decrease exclusively in the hADSCs group. These results showed that combinatorial effect of cell and gene-therapy does not improve the antifibrogenic effects of individual treatments, whereas hADSCs transplantation seems to reduce liver fibrosis in a greater proportion.

    This study presents a three-step validation technique to compare the performance of the Canadian Precipitation Analysis (CaPA) product relative to actual observation as a hydrologic forcing in regional watershed simulation. CaPA is an interpolated (6 h or 24 h accumulation) reanalysis precipitation product in near real time covering all of North America. The analysis procedure involves point-to-point (P2P) and map-to-map (M2M) comparisons, followed by proxy validation using an operational version of the WATFLOOD™ hydrologic model from 2002 to 2005 in the Lake Winnipeg Basin (LWB), Canada. The P2P technique using a Bayesian change point analysis shows that CaPA corresponds with actual observations (Canadian daily climate data, CDCD), on both an annual and seasonal basis. CaPA has the same spatial pattern, dependency and autocorrelation properties as CDCD pixel by pixel (M2M). When used as hydrologic forcing in WATFLOOD™, results indicate that CaPA is a reliable product for water resource modeling and predictions, but that the quality of CaPA data varies annually and seasonally, as does the quality of observations. CaPA proved most beneficial as a hydrologic forcing during winter seasons where observation quality is the lowest. Reanalysis products, such as CaPA, can be a reliable option in sparse network areas, and is beneficial for regional governments when the cost of new weather stations is prohibitive.

  3. Factors Influencing Divergent Patterns of Phosphorus Availability in NY and PA Biogeochemical `Hotspots'

    Anthropogenic alteration of the soil phosphorus (P) cycle leads to subsequent water quality issues in agricultural dominated watersheds. In the humid Northeastern United States (NE US), variably saturated areas can generate surface runoff that transports P and stimulates biogeochemical processes; these hydrologically dynamic locations are often called biogeochemical `hotspots'. Many studies have evaluated nitrogen and carbon cycling in biogeochemical hot spots but few have focused on P. We hypothesized seasonally wet parts of the landscape (i.e., hotspots) have smaller biologically available P pools because runoff events frequently carry away nutrients like P. To test this hypothesis, we generated soil wetness index (SWI) maps from soil (SURRGO) and elevation (LiDAR rescaled to 3 m) data and used these maps to direct seasonal soil sampling near Klingerstown, Pennsylvania (PA) and Ithaca, New York (NY). We collected 5cm deep soil samples in PA (bimonthly) and NY (monthly) along soil moisture gradients for a range of land cover types (forest, fallow, and cropped) from May through October. We measured soil moisture in the field and percent organic matter (OM), pH, and three increasingly strong soil P extractions (dilute-salt-extractable P, oxalate-extractable P, and total-extractable P) in the laboratory. Our results indicated a negative relationship between dilute-salt-extractable P concentrations and SWI in PA and no relationship between these same variables in NY. We also found positive relationships between each of the three P extractions in PA but only a positive relationship between oxalate-extractable P and total-extractable P in NY. Our findings in PA support our hypothesis; namely, less biologically available P (i.e. dilute-salt-extractable P) is found in wetter areas of the landscape. However, divergent P availability patterns in NY point to further complexities and confounding variables in our understanding in soil P processes. Further studies will look

However, uPA/SCID mice show four disadvantages: the human hepatocytes (h-heps replacement index in mouse liver is decreased due to deletion of uPA transgene by homologous recombination, kidney disorders are likely to develop, body size is small, and hemizygotes cannot be used as hosts as more frequent homologous recombination than homozygotes. To solve these disadvantages, we have established a novel host strain that has a transgene containing albumin promoter/enhancer and urokinase-type plasminogen activator cDNA and has a SCID background (cDNA-uPA/SCID. We applied the embryonic stem cell technique to simultaneously generate a number of transgenic lines, and found the line with the most appropriate levels of uPA expression-not detrimental but with a sufficiently damaged liver.

    Full Text Available Introduction Agricultural productions has been identified as a major contributor to atmospheric greenhouse gases (GHG on a global scale with about 14% of global net CO2 emissions coming from agriculture. Identification and assessment of environmental impact in the production system will be leading to achieve the goals of sustainable development, which would be achieved by life cycle assessment. To find the relationship between inputs and outputs of a production process, artificial intelligence (AI has drawn more attention rather than mathematical models to find the relationships between input and output variables by training, and produce results without any prior assumptions. The aims of this study were to life cycle assessment (LCA of Alfalfa production flow and prediction of GWP (global warming potential per ha produced alfalfa (kg CO2 eq.(ha alfalfa-1 with respect to inputs using ANFIS. Materials and Methods The sample size was calculated by using the Cochran method, to be equals 75, then the data were collected from 75 alfalfa farms in Bukan Township in Western Azerbaijan province using face to face questionnaire method.

    The fourth CCM (Consultative Committee for Mass and related quantities) International Conference on Pressure Metrology from Ultra-High Vacuum to Very High Pressures (10-9 Pa to 109 Pa) was held at the Institute of Physics in London from 19-21 April 2005. The event, which was organized by the Low, Medium and High Pressure working groups of the CCM, was attended by in excess of one hundred participants with representatives from five continents and every regional metrology organization. The purpose of this conference is to review all the work that is devoted to the highest quality of pressure measurement by primary standards as well as the dissemination of the pressure scale. A total of 52 papers were presented orally, and 26 as posters, in sessions that covered the following topics: Latest scientific advances in pressure and vacuum metrology Innovative transfer standards, advanced sensors and new instrument development Primary (top-level) measurement standards International and regional key comparisons New approaches to calibration It is interesting the note that since the third conference in 1999 the pressure range covered has increased by two orders of magnitude to 109 Pa, to take into account more exacting scientific and industrial demands for traceable vacuum measurement. A further feature of the conference was the increased range of instrumentation and techniques used in the realization and potential realization of pressure standards. Seton Bennett, Director of International Metrology at the National Physical Laboratory, opened the conference and Andrew Wallard, Director of the Bureau International des Poids et Mesures (BIPM), gave the keynote address which described the implementation of the mutual recognition arrangement and the resulting removal of metrological barriers to international trade. Many experts have contributed significant amounts of their time to organize the event and to review the submitted papers. Thanks are due to all of these people

    Numerous cofactors modulate the gene regulatory activity of glucocorticoid receptors (GRs) by affecting one or more of the following three major transcriptional properties: the maximal activity of agonists (Amax), the potency of agonists (EC50), and the partial agonist activity of antisteroids (PAA). Here, we report that the recently described nuclear protein, Pax2 transactivation domain interaction protein (PTIP)-associated protein 1 (PA1), is a new inhibitor of GR transactivation. PA1 suppresses Amax, increases the EC50, and reduces the PAA of an exogenous reporter gene in a manner that is independent of associated PTIP. PA1 is fully active with, and strongly binds to, the C-terminal half of GR. PA1 reverses the effects of the coactivator TIF2 on GR-mediated gene induction but is unable to augment the actions of the corepressor SMRT. Analysis of competition assays between PA1 and TIF2 with an exogenous reporter indicates that the kinetic definition of PA1 action is a competitive decelerator at two sites upstream from where TIF2 acts. With the endogenous genes IGFBP1 and IP6K3, PA1 also represses GR induction, increases the EC50, and decreases the PAA. ChIP and re-ChIP experiments indicate that PA1 accomplishes this inhibition of the two genes via different mechanisms as follows: PA1 appears to increase GR dissociation from and reduce GR transactivation at the IGFBP1 promoter regions but blocks GR binding to the IP6K3 promoter. We conclude that PA1 is a new competitive decelerator of GR transactivation and can act at more than one molecularly defined step in a manner that depends upon the specific gene. PMID:23161582

    The sediment 231Pa / 230Th activity ratio is emerging as an important proxy for deep ocean circulation in the past. In order to allow for a direct model-data comparison and to improve our understanding of the sediment 231Pa / 230Th activity ratio, we implement 231Pa and 230Th in the ocean component of the Community Earth System Model (CESM). In addition to the fully coupled implementation of the scavenging behavior of 231Pa and 230Th with the active marine ecosystem module (particle-coupled: hereafter p-coupled), another form of 231Pa and 230Th have also been implemented with prescribed particle flux fields of the present climate (particle-fixed: hereafter p-fixed). The comparison of the two forms of 231Pa and 230Th helps to isolate the influence of the particle fluxes from that of ocean circulation. Under present-day climate forcing, our model is able to simulate water column 231Pa and 230Th activity and the sediment 231Pa / 230Th activity ratio in good agreement with available observations. In addition, in response to freshwater forcing, the p-coupled and p-fixed sediment 231Pa / 230Th activity ratios behave similarly over large areas of low productivity on long timescales, but can differ substantially in some regions of high productivity and on short timescales, indicating the importance of biological productivity in addition to ocean transport. Therefore, our model provides a potentially powerful tool to help the interpretation of sediment 231Pa / 230Th reconstructions and to improve our understanding of past ocean circulation and climate changes.

    Full Text Available La imagen país de Colombia ha sido objeto de discusión en los campos de los negocios internacionales y el marketing territorial. Colombia es un país con un posicionamiento tradicional asociado al narcotráfico y al café, situación que ha llevado a los gobiernos de la última década a definir nuevas estrategias que ayuden a mejorar la reputación del país en mercados internacionales. Sin embargo, sus esfuerzos han sido de poco impacto porque la imagen país de Colombia todavía mantiene una asociación histórica negativa resultado del narcotráfico. En este sentido, el presente artículo aborda los resultados de una investigación realizada sobre las impresiones que tienen los mexicanos que han visitado y no han visitado a Colombia. Se eligió a México porque es el segundo emisor de turistas hacia Colombia procedentes de Norteamérica. Por medio de una investigación empírica aplicada a una muestra de 190 mexicanos mayores de 18 años, se encontró que el posicionamiento se mantiene negativo y se asocia al país con drogas, terrorismo, inseguridad y corrupción. Dicha percepción contrasta con un atributo que se destaca en el estudio, y es que se asocia a Colombia con la amabilidad de su población. Los resultados del estudio se obtuvieron finalizando el 2013. Palabras clave: Asociación; Colombia; imagen país; México; percepción; visitantes.Mexicans' impressions of Colombia's country imageAbstractThe country image of Colombia has been discussed in the fields of international business and territorial marketing.

    Fractional flow reserve (FFR) currently represents the gold standard in the evaluation of the haemodynamic relevance of coronary stenoses. However, both intracoronary and intravenous adenosine may be tolerated poorly by some patients. Therefore, considerable interest had been focused in the last few years on new adenosine-free indexes to define the haemodynamic relevance of coronary stenoses. So far, few data have been reported on resting Pd/Pa and its correlation with FFR as evaluated with high-dose intracoronary adenosine administration, which is the aim of the current study. FFR was assessed in 120 patients with 137 intermediate lesions during cardiac catheterization by a pressure-recording guidewire (PrimeWire). FFR was calculated as the ratio of the distal coronary pressure to the aortic pressure at hyperaemia. Intracoronary doses of adenosine were administered up to 720 μg as intracoronary boli. Exclusion criteria were as follows: (a) allergy to adenosine; (b) baseline bradycardia (heart rate values and increased the percentage of patients showing an FFR less than 0.80. Resting Pd/Pa showed good accuracy in the identification of patients with significant FFR values (value in the prediction of a positive FFR value. A value up to 0.88 was associated with a 100% positive predictive value, whereas a value of at least 0.95 was associated with a 95% negative predictive value. This study showed that in intermediate lesions, resting Pd/Pa was related linearly to FFR. We identified 0.93 as the best cut-off value in the prediction of haemodynamically significant coronary stenosis as evaluated by FFR. However, cut-off values of 0.88 and 0.95 could provide the maximal predictive positive and negative values, suggesting the additional use of FFR only in patients with resting values within this range.

    Full Text Available Background/Aims: Ovarian cancer (OC is the fifth leading cause of cancer-related death in women, and it is difficult to diagnose at an early stage. The purpose of this study was to explore the prognostic biological markers of OC. Methods: Univariate Cox regression analysis was used to identify genes related to OC prognosis from the Cancer Genome Atlas(TCGA database. Immunohistochemistry was used to analyse the level of SPINK13 in OC and normal tissues. Cell proliferation, apoptosis and invasion were performed using MTT assay, flow cytometric analysis and Transwell assay, respectively. Results: We identified the Kazal-type serine protease inhibitor-13 (SPINK13 gene related to OC prognosis from the Cancer Genome Atlas (TCGA database by univariate Cox regression analysis. Overexpression of SPINK13 was associated with higher overall survival rate in OC patients. Immunohistochemistry showed that the level of SPINK13 protein was significantly lower in OC tissues than in normal tissues (P < 0.05.In vitro experiments showed that the overexpression of SPINK13 inhibited cellular proliferation and promoted apoptosis. Moreover, SPINK13 inhibited cell migration and epithelial to mesenchymal transition (EMT. SPINK13 was found to inhibit the expression of urokinase-type plasminogen activator (uPA, while recombinant uPA protein could reverse the inhibitory effect of SPINK13 on OC metastasis. Conclusion: These results indicate that SPINK13 functions as a tumour suppressor. The role of SPINK13 in cellular proliferation, apoptosis and migration is uPA dependent, and SPINK13 may be used as a potential biomarker for diagnosis and targeted therapy in OC.

    Migration of low molecular mass compounds (LMMC), such as monomers and additives, from plastic packaging into food simulants is a very important issue, concerning public health and chemical contamination of foods. Sterilization of food packaging materials with ionizing radiation is considered an alternative to other sterilization methods, but when polymers are irradiated, LMMC may be formed, as radiolysis products. According to the Brazilian legislation, specific migration tests, such as those of LMMC from packaging into simulants, should be carried out at certain temperature and time, depending on the real conditions of contact. In this work, multilayer flexible films with polyamide 6 (PA-6), used for meat foodstuffs, were studied. The {epsilon}-caprolactam (PA-6 monomer) specific migration into acetic acid 3% simulant at 40 deg C during 10 days and at 100 deg C during 30 minutes was performed. The initial monomer level in the irradiated and non irradiated PA-6 films was quantified by high resolution gas chromatography (HRGC). Radiation doses were 3 and 7 kGy. {epsilon}-caprolactam specific migration was carried out only with non irradiated films. The results showed that radiation causes a significant change in the monomer level, up or down, depending on the multilayer film type. The kinetic of the {epsilon}-caprolactam migration at both temperatures, 40 and 100 deg C was clearly explained by the numerical simulation, combining an Arrhenius equation with the Fick's second law, although this kinetic was not experimentally studied. This simulation allowed to predict diffusion parameters estimates, like diffusion coefficients and activation energies of {epsilon}-caprolactam in the films or simulant. (author)

    The strategic plan for the next E-Area Low-Level Waste Facility Performance Assessment includes recommended changes to the screening criteria used to reduce the number of radioisotopes that are to be considered in the air and radon pathways incorporated into the GoldSim® atmospheric release model (ARM). For the air pathway, a revised screening methodology was developed based on refinement of previous E-Area PA screening approaches and consideration of the strategic plan recommendations. The revised methodology has three sequential screening steps for each radioisotope: (1) volatility test using the Periodic Table of the Elements, (2) stability test based on half-life, and (3) stability test based on volatility as measured by the Henry’s Law constant for the assumed dominant gaseous species or vapor pressure in the case of tritiated water. Of the 1252 radioisotopes listed in the International Commission on Radiological Protection Publication 107, only the 10 that satisfied all three steps of the revised screening methodology will be included in the ARM. They are: Ar-37, Ar-39, Ar-42, C-14, H-3, Hg-194, Hg-203, Kr-81, Kr-85, and Xe-127. For the radon pathway, a revised screening methodology was developed that also has three sequential steps: (1) identify all decay chains that terminate at Rn-222, (2) screen out parents that decay through U-238 because of its 4.5-billion-year primordial half-life, and (3) eliminate remaining parents whose half-life is shorter than one day. Of the 86 possible decay chains leading to Rn-222, six decay chains consist of 15 unique radioisotopes that will be incorporated into the ARM. The 15 radioisotopes are: U-238, Th-234, Pa-234m, Pu-238, U-234, Th-230, Ra-226, Cf-246, Cm-242, Am-242m, Am-242, Np-238, Np-234, Pa-230, and Rn-222.

  19. The distribution and behaviour of 230Th and 231 Pa at an ocean margin, Baja California, Mexico

    Uranium, Th and Pa isotopes were measured in sediments collected by box core along a transect normal to the Baja California continental margin. Six cores were analysed, ranging in depositional environment from manganese nodule-bearing, pelagic, red clay to hemipelagic sediments displaying Mn reduction in the upper 5 cm. In the hemipelagic cores, solid-phase Mn peaks due to diagenetic remobilisation occur within the upper layers which are well mixed with respect to unsupported 230 Th and 231 Pa. The fact that 230 Th and 231 Pa are not concentrated at the Mn peaks suggests that little mobility of these nuclides occurs within the sediment column. Unsupported 230 Th/ 231 Pa activity ratios in the biomixed layer of the sediments range from 10.9 to 6.6, generally decreasing towards the inshore stations. The flux of 230 Th and 231 Pa across the sediment/water interface is almost in balance with the theoretical water column supply in the most distal core, but rapidly increases inshore. This evidence from the sediment column confirms that enhanced 230 Th and 231 Pa removal occurs at ocean margins, and that 231 Pa is removed from the water column to the sediments in preference to 230 Th.

    Mounting evidence suggests that the urokinase plasminogen activator (uPA) and its receptor (uPAR) play a central role in tumor progression. The goal of this study was to develop an 89Zr-labeled, antibody-based positron emission tomography (PET) tracer for quantitative imaging of the uPA/uPAR system....... An anti-uPA monoclonal antibody (ATN-291) was conjugated with a deferoxamine (Df) derivative and subsequently labeled with 89Zr. Flow cytometry, microscopy studies, and competitive binding assays were conducted to validate the binding specificity of Df-ATN-291 against uPA. PET imaging with 89Zr-Df-ATN-291...... was carried out in different tumors with distinct expression levels of uPA. Biodistribution, histology examination, and Western blotting were performed to correlate tumor uptake with uPA or uPAR expression. ATN-291 retained uPA binding affinity and specificity after Df conjugation. 89Zr-labeling of ATN-291...

    Highlights: ► Homologous α and β subunits are alternatively arranged in the PA28 heptameric ring. ► The flexible loops of the three α subunits surround the site of substrate entry. ► The loops serve as gatekeepers that selectively hinder passage of longer peptides. - Abstract: A major form of proteasome activator PA28 is a heteroheptamer composed of interferon-γ-inducible α and β subunits, which share approximately 50% amino acid identity and possess distinct insert loops. This activator forms a complex with the 20S proteasome and thereby stimulates proteasomal degradation of peptides in an ATP-independent manner, giving rise to smaller antigenic peptides presented by major histocompatibility complex class I molecules. In this study, we performed biophysical and biochemical characterization of the structure and function of the PA28 hetero-oligomer. Deuteration-assisted small-angle neutron scattering demonstrated three α and four β subunits are alternately arranged in the heptameric ring. In this arrangement, PA28 loops surround the central pore of the heptameric ring (site for peptide entry). Activating the 20S proteasome with a PA28 mutant that lacked the α subunit loops cleaved model substrates longer than a nonapeptide with better efficiency when compared to wild-type PA28. Based on these data, we hypothesize that the flexible PA28 loops act as gatekeepers, which function to select the length of peptide substrates to be transported between the proteolytic chamber and the extra-proteasomal medium.

    The semiclassical model of nuclear reactions with loosely bound projectiles (V.P. Aleshin, B.I. Sidorenko, Acta Phys. Pol. B29, 325 (1998)) is refined and compared with experimental data of Rama Rao et al. on the excitation function for the production of 232,233 Pa in 6 Li+ 232 Th collisions at E = 30-50 MeV. The main contribution to the production of 232 Pa is the 2 neutron emission from excited states of 234 Pa formed in the ( 6 Li,α) reaction. The main source of 233 Pa is the ( 6 Li,αp) reaction followed by γ transitions from excited states of 233 Th to 233 Th (g.s.) which transforms to 233 Pa through β - decay. The ground state of 6 Li regarded as a combination of n+p+α is modeled with the K=2, l x =l y =0 hyperspherical function. The calculation underpredicts the excitation function of 232 Pa by a factor of 0.6 and overpredicts the excitation function of 233 Pa by a factor of 2.3, on the average. With the more realistic wave function of 6 Li both factors are expected to be closer to 1. (author)

    The NA50 Collaboration has measured heavy-quarkonium production in p-A collisions at 450 GeV incident energy (sqrt(s) = 29.1 GeV). We report here results on the production of the Upsilon states and of high-mass Drell-Yan muon pairs (m > 6 GeV). The cross-section at midrapidity and the A-dependence of the measured yields are determined and compared with the results of other fixed-target experiments and with the available theoretical estimates. Finally, we also address some issues concerning the transverse momentum distributions of the measured dimuons.

  10. Why is the radial flow in central pA collisions stronger than in AA?

    International Nuclear Information System (INIS)

    Kalaydzhyan, Tigran; Shuryak, Edward

    2014-01-01

    Both the transverse size and entropy density per area in central pA collisions is smaller than in central AA, and yet the radial flow is stronger. We propose an explanation to this puzzle. Using a weak attraction between strings through the σ-meson exchange, fitted to the lattice data, we find collective implosion of the “spaghetti” multi-string state. Collectivization of the sigma field of the strings is the QCD analog of the black hole formation occurring in holographic models

    Full Text Available Sweet cherry (Prunus avium L. is an important fruit crop in which fruit size is strongly associated with commercial value; few genes associated with fruit size have, however, been identified in sweet cherry. Members of the CYP78A subfamily, a group of important cytochrome P450s, have been found to be involved in controlling seed size and development in Arabidopsis thaliana, rice, soybean, and tomato. However, the influence of CYP78A members in controlling organ size and the underlying molecular mechanisms in sweet cherry and other fruit trees remains unclear. Here, we characterized a P. avium CYP78A gene PaCYP78A9 that is thought to be involved in the regulation of fruit size and organ development using overexpression and silencing approaches. PaCYP78A9 was significantly expressed in the flowers and fruit of sweet cherry. RNAi silencing of PaCYP78A9 produced small cherry fruits and PaCYP78A9 was found to affect fruit size by mediating mesocarp cell proliferation and expansion during fruit growth and development. Overexpression of PaCYP78A9 in Arabidopsis resulted in increased silique and seed size and PaCYP78A9 was found to be highly expressed in the inflorescences and siliques of transgenic plants. Genes related to cell cycling and proliferation were downregulated in fruit from sweet cherry TRV::PaCYP78A9-silencing lines, suggesting that PaCYP78A9 is likely to be an important upstream regulator of cell cycle processes. Together, our findings indicate that PaCYP78A9 plays an essential role in the regulation of cherry fruit size and provide insights into the molecular basis of the mechanisms regulating traits such as fruit size in P. avium.

    To detect the expressions of EMMPRIN and its ligand CyPA in gingival crevicular fluid (GCF) of chronic periodontitis (CP) patients and explore their possible relation to the status of periodontal inflammation. GCF of CP patients (group CP) and periodontitis-free patients with intact dentition (the control group) were collected and assayed for EMMPRIN and CyPA expressions by ELISA. The clinical periodontal status of these patients were examined. Statistical analysis was performed by use of SPSS 17.0 software package. Spearman's correlation analysis was utilized to determine the relationships between the expressions of EMMPRIN and CyPA in GCF and the clinical parameters. In addition, analysis of variance (ANOVA) was used for comparing the difference between group CP and the control group. In group CP, GCF volume was positively correlated with EMMPRIN total amount, CyPA total amount and some clinical periodontal indexes (GI,SBI,AL). EMMPRIN total amount was positively correlated with GCF volume, CyPA total amount and some of clinical periodontal indexes (GI,SBI,AL), but it was negatively correlated with smoking status (PEMMPRIN total amount and some of clinical periodontal indexes (GI,SBI,AL). In the control group,there were significant positive correlations among GCF volume, EMMPRIN total amount and CyPA total amount. The difference of GCF, EMMPRIN and CyPA between the 2 groups were statistically significant (PEMMPRIN and its ligand CyPA in GCF of periodontitis-free patients with intact dentition and CP patients were all detected. As the progress of periodontal inflammation, GCF secretion increases, as well as the expressions of EMMPRIN and CyPA in GCF.

    Fractional flow reserve (FFR) has been established as a useful diagnostic tool. The distal coronary pressure to aortic pressure (Pd/Pa) ratio at rest is a simpler physiologic index but also requires the use of the pressure wire, whereas recently proposed virtual functional indices derived from coronary imaging require complex blood flow modelling and/or are time-consuming. Our aim was to test the diagnostic performance of virtual resting Pd/Pa using routine angiographic images and a simple flow model. Three-dimensional quantitative coronary angiography (3D-QCA) was performed in 139 vessels (120 patients) with intermediate lesions assessed by FFR. The resting Pd/Pa for each lesion was assessed by computational fluid dynamics. The discriminatory power of virtual resting Pd/Pa against FFR (reference: ≤0.80) was high (area under the receiver operator characteristic curve [AUC]: 90.5% [95% CI: 85.4-95.6%]). Diagnostic accuracy, sensitivity and specificity for the optimal virtual resting Pd/Pa cut-off (≤0.94) were 84.9%, 90.4% and 81.6%, respectively. Virtual resting Pd/Pa demonstrated superior performance (pvirtual resting Pd/Pa and FFR (r=0.69, pVirtual resting Pd/Pa using routine angiographic data and a simple flow model provides fast functional assessment of coronary lesions without requiring the pressure-wire and hyperaemia induction. The high diagnostic performance of virtual resting Pd/Pa for predicting FFR shows promise for using this simple/fast virtual index in clinical practice.

    Full Text Available Cyclic phosphatidic acid (cPA is a naturally occurring phospholipid mediator with a unique cyclic phosphate ring at the sn-2 and sn-3 positions of its glycerol backbone. We have previously shown that cPA significantly suppresses ischemia-induced delayed neuronal death and the accumulation of glial fibrillary acidic protein in the CA1 region of the rat hippocampus. These results indicated that the systemic administration of cPA can protect hippocampal neurons against ischemia-induced delayed neuronal cell death. In the current study, we investigated the effects of cPA on neuronal cell death caused by hypoxia in vitro and the molecular mechanisms underlying these effects. We used cobalt chloride (CoCl(2 to expose cells to hypoxic conditions in vitro. Treating mouse neuroblastoma (Neuro2A cells with CoCl(2 induced nuclear DNA condensation and phosphatidylserine exposure. However, adding cPA led to the suppression of CoCl(2-induced apoptosis in a cPA dose-dependent manner and attenuated the increase in the Bax/Bcl-2 ratio caused by CoCl(2. Quantitative PCR analysis showed that Neuro2A cells strongly express the LPA(1, LPA(2, and LPA(6, which are G-protein coupled receptors that can be activated by cPA. To date, LPA(1 and LPA(2 have been reported to exhibit antiapoptotic activity. Therefore, to assess the roles of LPA(1 and LPA(2 on cPA-induced neuroprotective functions, Ki16425, a selective LPA(1 and LPA(3 antagonist, was adopted to know the LPA(1 function and siRNA was used to knockdown the expression of LPA(2. On the basis of our results, we propose that cPA-induced protection of Neuro2A cells from CoCl(2-induced hypoxia damage is mediated via LPA(2.

    PA-824 is a promising drug candidate for the treatment of tuberculosis (TB). It is in phase II clinical trials as part of the first newly designed regimen containing multiple novel antituberculosis drugs (PA-824 in combination with moxifloxacin and pyrazinamide). However, given that the genes involved in resistance against PA-824 are not fully conserved in the Mycobacterium tuberculosis complex (MTBC), this regimen might not be equally effective against different MTBC genotypes. To investigate this question, we sequenced two PA-824 resistance genes (fgd1 [Rv0407] and ddn [Rv3547]) in 65 MTBC strains representing major phylogenetic lineages. The MICs of representative strains were determined using the modified proportion method in the Bactec MGIT 960 system. Our analysis revealed single-nucleotide polymorphisms in both genes that were specific either for several genotypes or for individual strains, yet none of these mutations significantly affected the PA-824 MICs (≤0.25 μg/ml). These results were supported by in silico modeling of the mutations identified in Fgd1. In contrast, “Mycobacterium canettii” strains displayed a higher MIC of 8 μg/ml. In conclusion, we found a large genetic diversity in PA-824 resistance genes that did not lead to elevated PA-824 MICs. In contrast, M. canettii strains had MICs that were above the plasma concentrations of PA-824 documented so far in clinical trials. As M. canettii is also intrinsically resistant against pyrazinamide, new regimens containing PA-824 and pyrazinamide might not be effective in treating M. canettii infections. This finding has implications for the design of multiple ongoing clinical trials.
