Energy sector assistance in developing countries: Current trends and policy recommendations

International Nuclear Information System (INIS)

Tharakan, Pradeep J.; Castro, Julio de; Kroeger, Timm

2007-01-01

An estimated 2.5 billion people remain without access to modern energy supplies. This shortfall is expected to grow as the population in developing countries continues to grow rapidly and the existing infrastructure ages. The United Nations' goal of lowering poverty by half by 2015 will not be attained unless the poor in developing countries gain greater access to basic infrastructure and services, including energy services. The key objective of this paper is to analyze trends in overseas development assistance (ODA) to the energy sector in developing countries during the period 1990-2003, relative to realized private sector investments. This analysis then forms the basis for policy recommendations for consideration by decision makers within countries that are major contributors to ODA

Every year river floods cause enormous damage around the world. Recent major floods in North America and Europe, for example, have received much press, with some concluding that these floods are more frequent in recent years as a result of anthropogenic warming. There has been considerable scientific effort invested in establishing whether observed flood records show evidence of trends or variability in flood frequency, and to determine whether these patterns can be linked to climatic changes. However, the river catchments used in many published studies are influenced by direct human alteration such as reservoir regulation and urbanisation, which can confound the interpretation of climate-driven variability. Furthermore, a majority of previous studies have analysed changes in low magnitude floods, such as the annual peak flow, at a national scale. Few studies are known that have analysed changes in large floods (greater than 25-year floods) on a continental scale. To fill this research gap, we present a study analysing flood flows from reference hydrologic networks (RHNs) or RHN-like gauges across a large study domain embracing North America and much of Europe. RHNs comprise gauging stations with minimally disturbed catchment conditions, which have a near-natural flow regime and provide good quality data; RHN analyses thus allow hydro-climatic variability to be distinguished from direct artificial disturbances or data inhomogeneities. One of the key innovations in this study is the definition of an RHN-like network consisting of 1204 catchments on a continental scale. The network incorporates existing, well-established RHNs in Canada, the US, the UK, Ireland and Norway, alongside RHN-like catchments from Europe (France, Switzerland, Iceland, Denmark, Sweden, Finland, Spain), which have been incorporated in the network following a major effort to ensure RHN-like status of candidate gauges through consultation with local experts. As the aim of the study is to examine

Carbon Capture and Storage Development Trends from a Techno-Paradigm Perspective

Directory of Open Access Journals (Sweden)

Bobo Zheng

2014-08-01

Full Text Available The world’s energy needs have been continually growing over the past decade, yet fossil fuels are limited. Renewable energies are becoming more prevalent, but are still a long way from being commonplace worldwide. Literature mining is applied to review carbon capture and storage (CCS development trends and to develop and examine a novel carbon capture and storage technological paradigm (CCSTP, which incorporates CCSTP competition, diffusion and shift. This paper first provides an overview of the research and progress in CCS technological development, then applies a techno-paradigm theory to analyze CCSTP development and to provide a guide for future CCS technological trends. CCS could avoid CO2 being released into the atmosphere. Moreover, bioenergy with CCS (BECCS can make a significant contribution to a net removal of anthropogenic CO2 emissions. In this study, we compare the different CCSTP developmental paths and the conventional techno-paradigm by examining the S-curves. The analyses in this paper provide a useful guide for scholars seeking new inspiration in their research and for potential investors who are seeking to invest research funds in more mature technologies. We conclude that political barriers and public acceptance are the major distinctions between the CCSTP and the conventional techno-paradigm. It is expected that policy instruments and economic instruments are going to play a pivotal role in the accomplishment of global carbon reduction scenarios.

Analysis of long-term trends (1950–2009) in precipitation, runoff and runoff coefficient in major urban watersheds in the United States

International Nuclear Information System (INIS)

Velpuri, N M; Senay, G B

2013-01-01

This study investigates the long-term trends in precipitation, runoff and runoff coefficient in major urban watersheds in the United States. The seasonal Mann–Kendall trend test was performed on monthly precipitation, runoff and runoff coefficient data from 1950 to 2009 obtained from 62 urban watersheds covering 21 major urban centers in the United States. The results indicate that only five out of 21 urban centers in the United States showed an uptrend in precipitation. Twelve urban centers showed an uptrend in runoff coefficient. However, six urban centers did not show any trend in runoff coefficient, and three urban centers showed a significant downtrend. The highest rate of change in precipitation, runoff and runoff coefficient was observed in the Houston urban watershed. Based on the results obtained, we also attributed plausible causes for the trends. Our analysis indicated that while a human only influence is observed in most of the urban watersheds, a combined climate and human influence is observed in the central United States. (letter)

Accompanying these trends are propositions based on current available evidence. These testable propositions should be considered when designing, implementing, and evaluating global health care leadership development models and programs. One particular leadership development model, a multilevel identity model, is presented as a potential model to use for leadership development. Other, complementary approaches, such as positive psychology and empowerment strategies, are discussed in relation to leadership identity formation. Specific issues related to global leadership are reviewed, including cultural intelligence and global mindset. An example is given of a nurse leadership development model that has been empirically tested in Canada. Through formal practice–academic–community collaborations, this model has been locally adapted and is being used for nurse leader training in Hong Kong, Taiwan, and Brazil. Collaborative work is under way to adapt the model for interprofessional health care leadership development. Keywords: health care leadership, development models, global trends, collective

Full Text Available Rationale. Pneumonia is a leading cause of postoperative complication. Objective. To examine trends, factors, and mortality of postoperative pneumonia following major cancer surgery (MCS. Methods. From 1999 to 2009, patients undergoing major forms of MCS were identified using the Nationwide Inpatient Sample (NIS, a Healthcare Cost and Utilization Project (HCUP subset, resulting in weighted 2,508,916 patients. Measurements. Determinants were examined using logistic regression analysis adjusted for clustering using generalized estimating equations. Results. From 1999 to 2009, 87,867 patients experienced pneumonia following MCS and prevalence increased by 29.7%. The estimated annual percent change (EAPC of mortality after MCS was −2.4% (95% CI: −2.9 to −2.0, P<0.001; the EAPC of mortality associated with pneumonia after MCS was −2.2% (95% CI: −3.6 to 0.9, P=0.01. Characteristics associated with higher odds of pneumonia included older age, male, comorbidities, nonprivate insurance, lower income, hospital volume, urban, Northeast region, and nonteaching status. Pneumonia conferred a 6.3-fold higher odd of mortality. Conclusions. Increasing prevalence of pneumonia after MCS, associated with stable mortality rates, may result from either increased diagnosis or more stringent coding. We identified characteristics associated with pneumonia after MCS which could help identify at-risk patients in order to reduce pneumonia after MCS, as it greatly increases the odds of mortality.

Hypertension in Developing Countries: A Major Challenge for the Future.

Science.gov (United States)

Mohsen Ibrahim, M

2018-05-01

Outline recent epidemiologic data regarding hypertension in developing countries, distinguish differences from developed countries, and identify challenges in management and future perspectives. Increased sugar intake, air and noise pollution, and low birth weight are emerging hypertension risk factors. The major challenges in management are difficulties in accurate diagnosis of hypertension and adequate blood pressure control. In contrast to developed countries, hypertension prevalence rates are on the rise in developing countries with no improvement in awareness or control rates. The increasing burden of hypertension is largely attributable to behavioral factors, urbanization, unhealthy diet, obesity, social stress, and inactivity. Health authorities, medical societies, and drug industry can collaborate to improve hypertension control through education programs, public awareness campaigns, legislation to limit salt intake, encourage generic drugs, development and dissemination of national guidelines, and involving nurses and pharmacists in hypertension management. More epidemiologic data are needed in the future to identify reasons behind increased prevalence and poor blood pressure control and examine trends in prevalence, awareness, treatment, and control. National programs for better hypertension control based on local culture, economic characteristics, and available resources in the population are needed. The role of new tools for hypertension management should be tested in developing world.

Vinnem, Jan Erik; Aven, Terje; Husebo, Torleif; Seljelid, Jorunn; Tveit, Odd J.

2006-01-01

The Petroleum Safety Authority Norway (PSA, formerly Norwegian Petroleum Directorate) took in 1999 the initiative to develop a method in order to assess trends and status for the risk levels in the Norwegian offshore petroleum industry. A method was developed, and a pilot study report was issued in April 2001, covering the period 1996-2000. Annual updates have been performed since then, and the latest report covers the period 1996-2004. The statistical approach is based on recording occurrence of near misses and relevant incidents, performance of barriers and results from risk assessments. Of similar importance is an evaluation of safety culture, motivation, communication and perceived risk. This is covered through the use of social science methods, such as questionnaire surveys and a number of interviews, audit and inspection reports as well as accident and incident investigations. There are also indicators for occupational accidents and occupational illness/-physical working environment factors. The focus is on the major hazard risk components for personnel staying on the offshore installations. An overview of the indicators used to illustrate these risk aspects is presented, followed by a discussion of the analytical approach used for these indicators. Results from the risk assessment for the Norwegian Continental Shelf in the period 1996-2004 are used throughout for illustration, and discussion of challenges

Highlights: • Governments’ strategies set important frameworks to develop and sustain low-carbon energy technologies. • Commercial activities play a key role in the low-carbon energy technologies’ development. • The number of patents that are based upon basic research is growing. - Abstract: Eco-innovations are being recognized as fundamental means to foster sustainable development, as well as to create new business opportunities. Nowadays, the eco-innovation concept is gaining ground within both academic and practitioner studies with the attempt to better understand the main dynamics underlying its nature and guide policymakers and companies in supporting its development. This paper contributes to the extant literature on eco-innovation by providing a comprehensive overview of the evolution of a specific type of eco-innovations that are playing a crucial role in the current socio-economic agenda, namely low-carbon energy technologies. Accordingly, we focus our attention on the related patenting activity of different countries and organizations over time, as well as on influencing policy initiatives and events. Hence, we collected 131,661 patents granted at the United States Patent and Trademark Office (U.S.PTO.) between 1971 and 2010, and belonging to the “Nuclear power generation”, “Alternative energy production”, and “Energy conservation” technological classes, as indicated by the International Patent Classification (IPC) Green Inventory. Our findings report the development trends of low-carbon energy technologies, as well as identify major related environmental programs, historical events, and private sector initiatives explaining those trends, hence revealing how these different circumstances have significantly influenced their development over time

Trends in diet and Alzheimer's disease during the nutrition transition in Japan and developing countries.

Science.gov (United States)

Grant, William B

2014-01-01

Alzheimer's disease (AD) rates in Japan and developing countries have risen rapidly in recent years. Researchers have associated factors such as the Western diet, obesity, alcohol consumption, and smoking with risk of AD. This paper evaluates whether the dietary transition might explain the rising trend of AD prevalence in Japan and in developing countries, evaluating other factors when possible. This study used two approaches to see whether dietary or other changes could explain AD trends in Japan and developing countries. One approach involved comparing trends of AD in Japan with changes in national dietary supply factors, alcohol consumption, and lung cancer mortality rates from zero to 25 years before the prevalence data. The second compared AD prevalence values for eight developing countries with dietary supply factors from zero to 25 years before the prevalence data. For Japan, alcohol consumption, animal product, meat and rice supply, and lung cancer rates correlated highly with AD prevalence data, with the strongest correlation for a lag of 15-25 years. In the eight-country study, total energy and animal fat correlated highly with AD prevalence data, with a lag of 15-20 years. Mechanisms to explain the findings include increased obesity for the eight countries, and increases in cholesterol, saturated fat, and iron from increases in animal products and meat supply for Japan. Evidently AD rates will continue rising in non-Western countries for some time unless we address major risk factors involving diet, obesity, and smoking.

2009-12-01

Full Text Available Global warming or the increase of the surface and atmospheric temperatures of the Earth, is increasingly discernible in the polar, sub-polar and major land glacial areas. The Himalayan and Tibetan Plateau Glaciers, which are the largest glaciers outside of the Polar Regions, are showing a large-scale decrease of snow cover and an extensive glacial retreat. These glaciers such as Siachen and Gangotri are a major water resource for Asia as they feed major rivers such as the Indus, Ganga and Brahmaputra. Due to scarcity of ground measuring stations, the long-term observations of atmospheric temperatures acquired from the Microwave Sounding Unit (MSU since 1979–2008 is highly useful. The lower and middle tropospheric temperature trend based on 30 years of MSU data shows warming of the Northern Hemisphere's mid-latitude regions. The mean month-to-month warming (up to 0.048±0.026°K/year or 1.44°K over 30 years of the mid troposphere (near surface over the high altitude Himalayas and Tibetan Plateau is prominent and statistically significant at a 95% confidence interval. Though the mean annual warming trend over the Himalayas (0.016±0.005°K/year, and Tibetan Plateau (0.008±0.006°K/year is positive, the month to month warming trend is higher (by 2–3 times, positive and significant only over a period of six months (December to May. The factors responsible for the reversal of this trend from June to November are discussed here. The inequality in the magnitude of the warming trends of the troposphere between the western and eastern Himalayas and the IG (Indo-Gangetic plains is attributed to the differences in increased aerosol loading (due to dust storms over these regions. The monthly mean lower-tropospheric MSU-derived temperature trend over the IG plains (dust sink region; up to 0.032±0.027°K/year and dust source regions (Sahara desert, Middle East, Arabian region, Afghanistan-Iran-Pakistan and Thar Desert regions; up to 0.068±0.033�

Mann, Allison; DiPrete, Thomas A.

2013-01-01

Numerous theories have been put forward for the high and continuing levels of gender segregation in science, technology, engineering, and mathematics (STEM) fields, but research has not systematically examined the extent to which these theories for the gender gap are consistent with actual trends. Using both administrative data and four separate longitudinal studies sponsored by the U.S. Department of Education’s National Center for Education Statistics (NCES), we evaluate several prominent explanations for the persisting gender gap in STEM fields related to mathematics performance and background and general life goals, and find that none of them are empirically satisfactory. Instead, we suggest that the structure of majors and their linkages to professional training and careers may combine with gender differences in educational goals to influence the persisting gender gap in STEM fields. An analysis of gendered career aspirations, course-taking patterns, and pathways to medical and law school supports this explanation. PMID:24090849

Numerous theories have been put forward for the high and continuing levels of gender segregation in science, technology, engineering, and mathematics (STEM) fields, but research has not systematically examined the extent to which these theories for the gender gap are consistent with actual trends. Using both administrative data and four separate longitudinal studies sponsored by the U.S. Department of Education's National Center for Education Statistics (NCES), we evaluate several prominent explanations for the persisting gender gap in STEM fields related to mathematics performance and background and general life goals, and find that none of them are empirically satisfactory. Instead, we suggest that the structure of majors and their linkages to professional training and careers may combine with gender differences in educational goals to influence the persisting gender gap in STEM fields. An analysis of gendered career aspirations, course-taking patterns, and pathways to medical and law school supports this explanation. Copyright © 2013 Elsevier Inc. All rights reserved.

This study visualized and analyzed the developing trends and hot topics in natural disaster research. 19694 natural disaster-related articles (January 1900 to June 2015) are indexed in the Web of Science database. The first step in this study is using complex networks to visualize and analyze these articles. CiteSpace and Gephi were employed to generate a countries collaboration network and a disciplines collaboration network, and then attached hot topics to countries and disciplines, respectively. The results show that USA, China, and Italy are the three major contributors to natural disaster research. "Prediction model", "social vulnerability", and "landslide inventory map" are three hot topics in recent years. They have attracted attention not only from large countries like China but also from small countries like Panama and Turkey. Comparing two hybrid networks provides details of natural disaster research. Scientists from USA and China use image data to research earthquakes. Indonesia and Germany collaboratively study tsunamis in the Indian Ocean. However, Indonesian studies focus on modeling and simulations, while German research focuses on early warning technology. This study also introduces an activity index (AI) and an attractive index (AAI) to generate time evolution trajectories of some major countries from 2000 to 2013 and evaluate their trends and performance. Four patterns of evolution are visible during this 14-year period. China and India show steadily rising contributions and impacts, USA and England show relatively decreasing research efforts and impacts, Japan and Australia show fluctuating activities and stable attraction, and Spain and Germany show fluctuating activities and increasing impacts.

"... Good population health is a crucial input into poverty reduction, economic growth and long-term economic development... This point is widely recognised by analysts and policy makers, but is greatly underestimated in its qualitative and quantitative significance, and in the investment allocations of many developing country and donor governments."--Commission on Macroeconomics and Health The international health development scene has changed rapidly during the past 5 years. From being a merely bilateral effort together with a few multilateral organisations and many NGOs new global partnerships have entered the scene and become major funding agencies. The provision of aid has also changed from small-scale project basis to financial support of large programmes. The purpose of this article is to describe some of the major transformations taken place in the organising, delivery and objective of international health development. But before presenting the new international health development agenda, a short introduction to the challenges inducing the need for renewed thinking about international aid is shortly presented.

Ayurveda is a traditional healthcare system of Indian medicine since ancient times. Several Ayurvedic medicines have been exploiting for treatment and management of various diseases in human beings. The several drugs have been developed and practiced from Ayurveda since ancient time to modern practice as 'tradition to trend'. The potential of Ayurvedic medicine needs to be explored further with modern scientific validation approaches for better therapeutic leads. The present study was aimed to explore the various aspects of Ayurveda and inspired drug discovery approaches for its promotion and development. We have reviewed all the literature related to the history and application of Ayurvedic herbs. Various aspects for the quality control, standardization, chemo-profiling, and metabolite fingerprinting for quality evaluation of Ayurvedic drugs. The development of Ayurvedic drugs is gaining momentum with the perspectives of safety, efficacy and quality for promotion and management of human health. Scientific documentation, process validation and several others significant parameters are key points, which can ensure the quality, safety and effectiveness of Ayurvedic drugs. The present review highlights on the major goal of Ayurveda and their significant role in healthcare system. Ayurveda deals with several classical formulations including arka, asavas, aristas, churna, taila, vati, gutika, bhasma etc. There are several lead molecules that have been developed from the Ayurvedic herbs, which have various significant therapeutic activities. Chemo-profiling of Ayurvedic drug is essential in order to assess the quality of products. It deals with bioactive compound quantification, spurious and allied drug determination, chromatographic fingerprinting, standardization, stability and quality consistency of Ayurvedic products.

The current context of intense social, economic and political transformations has contributed to changes in the health profile of the population and generated discussions about the impact of these changes on the reorganization of society. At the present moment, the increase in non-communicable illnesses and diseases raises major concerns about the paradox of malnutrition and obesity. Based on an in-depth reading and interpretation of texts, documents and databases, this article discusses issues related to nutrition, considering the dimensions of shortages and excesses, the evolution of nutrition over time, and the connection with the new epidemiological trend. We begin with a conceptual characterization, the historical background and the anthropological connections with the guiding theme of the article. We then describe the prevalence, distribution and secular trend of malnutrition and obesity, as well as the temporal relationship with the new epidemiological trend in Brazil within a context of development and inequalities. Finally, we reflect on the issue of (mal)nutrition in post-modernity, the new interests at stake in the health-disease process, as well as international experiences and strategies of partnerships designed to overcome these problems. We conclude by discussing some current advances and challenges in relation to the complexity and speed of contemporary changes.

With the growth of urban agglomerations, assessing the drivers of variability of air quality in and around the main anthropogenic emission hotspots has become a major societal concern as well as a scientific challenge. These drivers include emission changes and meteorological variability; both of them can be investigated by means of numerical modelling of trends over the past few years. A collaborative effort has been developed in the framework of the CityZen European project to address this question. Several chemistry and transport models (CTMs) are deployed in this activity: four regional models (BOLCHEM, CHIMERE, EMEP and EURAD) and three global models (CTM2, MOZART, and TM4). The period from 1998 to 2007 has been selected for the historic reconstruction. The focus for the present preliminary presentation is Europe. A consistent set of emissions is used by all partners (EMEP for the European domain and IPCC-AR5 beyond) while a variety of meteorological forcing is used to gain robustness in the ensemble spread amongst models. The results of this experiment will be investigated to address the following questions: - Is the envelope of models able to reproduce the observed trends of the key chemical constituents? - How the variability amongst models changes in time and space and what does it tell us about the processes driving the observed trends? - Did chemical regimes and aerosol formation processes changed in selected hotspots? Answering the above questions will contribute to fulfil the ultimate goal of the present study: distinguishing the respective contribution of meteorological variability and emissions changes on air quality trends in major anthropogenic emissions hotspots.

Life expectancy (LE) is a major marker of individual survival. It also serves as a guide to highlight both the progress and the gaps in total social and societal health. Comparative LE in concert with measures of gender-specific experience, indices of empowerment and societal happiness and development offer a comparative tool to examine trends and similarities of societal progress as seen through the lens of cross-national experience. To determine the gender gaps in LE (GGLE) trends, we performed a longitudinal analysis, covering a period of 49 years (1960-2008). To examine the association of GGLE with development indices, we used the 2007 GGLE data, the newest happiness data mostly drawn from 2006; the 2006 Human Development Index (HDI) data and the 2006 Gender Empowerment Measure (GEM) data. It revealed that most of the Organization for Economic Co-operation and Development (OECD) countries had a GGLE trend that occurred in an inverted U-curve fashion. We divided them into three subgroups based on the peak years of respective GGLE. The earlier the peak year, the happier the countries, the higher the HDI and the smaller the current GGLE are. Association analysis indicates that Happiness, HDI and GEM are all negatively associated with GGLE. This pattern suggests that GGLE undergoes three phases of growth, peak and stability and decline. Japan will soon be seeing its GGLE gradually shrinking in the foreseeable future. The continuing increases in Happiness, HDI and GEM are associated with a decrease in GGLE, which should be carefully taken into consideration.

In arid and semi-arid regions, water scarcity is the crucial issue for crop production. Identifying the spatial and temporal trends in aridity, especially during the crop-growing season, is important for farmers to manage their agricultural practices. This will become especially relevant when considering climate change projections. To reliably determine the actual trends, the influence of short- and long-term memory should be removed from the trend analysis. The objective of this study is to investigate the effect of short- and long-term memory on estimates of trends in two aridity indicators—the inverted De Martonne (ϕ IDM ) and Budyko (ϕ B ) indices. The analysis is done using precipitation and temperature data over Iran for a 50-year period (1966-2015) at three temporal scales: annual, wheat-growing season (October-June), and maize-growing season (May-November). For this purpose, the original and the modified Mann-Kendall tests (i.e., modified by three methods of trend free pre-whitening (TFPT), effective sample size (ESS), and long-term persistence (LTP)) are used to investigate the temporal trends in aridity indices, precipitation, and temperature by taking into account the effect of short- and long-term memory. Precipitation and temperature data were provided by the Islamic Republic of Iran Meteorological Organization (IRIMO). The temporal trend analysis showed that aridity increased from 1966 to 2015 at the annual and wheat-growing season scales, which is due to a decreasing trend in precipitation and an increasing trend in mean temperature at these two timescales. The trend in aridity indices was decreasing in the maize-growing season, since precipitation has an increasing trend for most parts of Iran in that season. The increasing trend in aridity indices is significant in Western Iran, which can be related to the significantly more negative trend in precipitation in the West. This increasing trend in aridity could result in an increasing crop water

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

1998-12-01

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

The future of oil has become an important topic of the discussion of energy policy in China. This paper attempts to present a full picture of the current status and future trends of China’s oil development through system analysis. First, we map a Sankey diagram of China’s oil flow to reveal the physical pattern of China’s oil supply and consumption. Then, we present the historical and ongoing trends of China’s oil flow from key aspects such as oil demand, oil resource availability, technology improvement, and policy adjustment. Based on these understandings, we design three scenarios of China’s oil demand in 2030, and analyze policy implications for oil saving, automotive energy development, and energy security. From the analysis, we draw some conclusions for policy decisions, such as to control the total oil consumption to avoid energy security risks, to enhance oil saving in all sectors with road transportation as the emphasis, and to increase the investment on oil production and refining to secure oil supply and reduce emissions. - Highlights: ► A Sankey Diagram to reveal the physical pattern of China’s oil supply and consumption. ► Present the ongoing trends of China’s oil development. ► Discuss important policy issues such as oil saving, energy security, and emissions reduction.

Communicable disease outbreaks cause millions of deaths throughout Sub-Saharan Africa each year. Most of the diseases causing epidemics in the region have been nearly eradicated or brought under control in other parts of the world. In recent years, considerable effort has been directed toward public health initiatives and strategies with a potential for significant impact in the fight against infectious diseases. In 1998, the World Health Organization African Regional Office (WHO/AFRO) launched the Integrated Disease Surveillance and Response (IDSR) strategy aimed at mitigating the impact of communicable diseases, including epidemic-prone diseases, through improving surveillance, laboratory confirmation and appropriate and timely public health interventions. Over the past decade, WHO and its partners have been providing technical and financial resources to African countries to strengthen epidemic preparedness and response (EPR) activities. This review examined the major epidemics reported to WHO/AFRO from 2003 to 2007. we conduct a review of documents and reports obtained from WHO/AFRO, WHO inter-country team, and partners and held meeting and discussions with key stakeholders to elicit the experiences of local, regional and international efforts against these epidemics to evaluate the lessons learned and to stimulate discussion on the future course for enhancing EPR. The most commonly reported epidemic outbreaks in Africa include: cholera, dysentery, malaria and hemorrhagic fevers (e.g. Ebola, Rift Valley fever, Crimean-Congo fever and yellow fever). The cyclic meningococcal meningitis outbreak that affects countries along the "meningitis belt" (spanning Sub-Saharan Africa from Senegal and The Gambia to Kenya and Ethiopia) accounts for other major epidemics in the region. The reporting of disease outbreaks to WHO/AFRO has improved since the launch of the IDSR strategy in 1998. Although the epidemic trends for cholera showed a decline in case fatality rate (CFR

Prestudy - Development of trend analysis of component failure

International Nuclear Information System (INIS)

Poern, K.

1995-04-01

The Bayesian trend analysis model that has been used for the computation of initiating event intensities (I-book) is based on the number of events that have occurred during consecutive time intervals. The model itself is a Poisson process with time-dependent intensity. For the analysis of aging it is often more relevant to use times between failures for a given component as input, where by 'time' is meant a quantity that best characterizes the age of the component (calendar time, operating time, number of activations etc). Therefore, it has been considered necessary to extend the model and the computer code to allow trend analysis of times between events, and also of several sequences of times between events.

Summarizing the status of drugs in the market and examining the trend of drug research and development is important in drug discovery. In this study, we compared the drug targets and the market sales of the new molecular entities approved by the U.S. Food and Drug Administration from January 2000 to December 2009. Two networks, namely, the target-target and drug-drug networks, have been set up using the network analysis tools. The multi-target drugs have much more potential, as shown by the network visualization and the market trends. We discussed the possible reasons and proposed the rational strategies for drug research and development in the future.

Overwork-related disorders, such as cerebrovascular/cardiovascular diseases (CCVD) and mental disorders due to overwork, are a major occupational and public health issue worldwide, particularly in East Asian countries. This report discusses the recent trend of overwork-related disorders in Japan from the perspective of workers' compensated occupational diseases, as well as the development of a national policy for preventive measures against overwork-related disorders in Japan. Recently, the number of claimed and compensated cases of occupational mental disorders has increased substantially, particularly among young workers, as compared to those of occupational CCVD. In response to these situations and action from society, the Japanese Government passed the "Act on Promotion of Preventive Measures against Karoshi and Other Overwork-Related Health Disorders" in June 2014 to develop a national initiative towards the prevention of overwork-related disorders. Changes in the trend of overwork-related disorders in Japan under a legal foundation and an initiative by the central government should be closely monitored so that other countries can benefit from the experiences.

1977-01-01

The paper presents a review of the technical developments which the containment systems of BWRs, PWRs and HWRs have undergone in the USA, Europe and Canada. The great variety of existing containment systems have been classified for each type of reactor, according to: principle of operation (i.e. dry containment; pressure suppression containment; containment with vacuum building; sub-atmospheric containment; etc.); type and number of the physical barriers provided against the dispersion of fission products to the environment (single containment, double containment, single containment with local collection of the leaks from the most probable leakage paths, or with pressurization of the potential leakage paths, etc.); and structural characteristics of the containment barriers (reinforced concrete, prestressed concrete, metal containment, liners). In the framework of this classification the main features of the various containment systems are illustrated, with special emphasis on the most modern designs. The difference in trend among various countries and various designers are highlighted. A review is also made of the various containment auxiliary systems which would operate in accident conditions (isolation systems, heat removal system, atmosphere control system, etc.). Also for these systems the main design criteria are set forth and present trends are described. Finally, a brief survey is also made of the present trends with regards to the design of containment structures against external events be they of natural origin (earthquake, tornadoes, etc.) or connected with human activities (airplane crash, explosions, etc.) [fr

Full Text Available In more than 30 years after China’s reform and opening to the outside world the non-governmental higher education has developed dramatically and enjoyed more and more favorable conditions, making great contributions to the popularization of higher education in China. According to the definition that “The non-governmental higher education is a major growth point for development of educational career and an important driving force in promoting educational reform”, quoting from The planning outline on the national medium and long-term educational reform and development (The Planning Outline for short issued in 2010 by China’s State Council, China has launched policies of greatly supporting the non-governmental higher education and designed the reform goals of the government as the main body of education, with the active participation of the whole society, and the mutual development of the governmental and non-governmental higher education. Soon afterwards, the nation has started the move of the non-governmental educational system, and positively explored the management of classification of profit and non-profit non-governmental educational institutions. Thus, the development of the Chinese non-governmental institutions of higher learning has been greatly influenced because of the policies and relevant practices. With the opening of the 18th national congress and the political direction mentioned in the report as “encouraging and guiding social organizations to initiate education”, the pace of development of the non-governmental institutions of higher learning will be accelerated and some new development trends will become clearer.

Existing trend curves do not account for previous and more recently observed test and power reactor flux-level, thermal neutron and γ-ray field-induced effects. Any agreement between measured data and trend curve predictions that does not adequately represent the important neutron environmental and temperature effects as well as the microstructural damage processes, therefore, could be fortuitous. Empirically derived end-of-life (EOL) and life-extension-range (LER) trend curves are presented and discussed in this paper for high temperature [∼288 0 C (550 0 F)] irradiation of two weld, two plate, and two forging pressure vessel (PV) steels and low-temperature [∼60 0 C (140 0 F)] irradiation of one support structure-type steel

Recent developments and future trends in nuclear medicine instrumentation

Zaidi, H.

2006-01-01

Molecular imaging using high-resolution single-photon emission computed tomography (SPECT) and positron emission tomography (PET) has advanced elegantly and has steadily gained importance in the clinical and research arenas. Continuous efforts to integrate recent research findings for the design of different geometries and various detector technologies of SPECT and PET cameras have become the goal of both the academic community and nuclear medicine industry. As PET has recently become of more interest for clinical practice, several different design trends seem to have developed. Systems are being designed for ''low cost'' clinical applications, very high-resolution research applications (including small-animal imaging), and just about everywhere in-between. The development of dual-modality imaging systems has revolutionized the practice of nuclear medicine. The major advantage being that SPECT/PET data are intrinsically aligned to anatomical information from the X-ray computed tomography (CT), without the use of external markers or internal landmarks. On the other hand, combining PET with magnetic resonance imaging (MRI) technology is scientifically more challenging owing to the strong magnetic fields. Nevertheless, significant progress has been made resulting in the design of a prototype small animal PET scanner coupled to three multichannel photomultipliers via optical fibers, so that the PET detector can be operated within a conventional MR system. Thus, many different design paths are being pursued - which ones are likely to be the main stream of future commercial systems? It will be interesting, indeed, to see which technologies become the most popular in the future. This paper briefly summarizes state-of-the art developments in nuclear medicine instrumentation. Future prospects will also be discussed. (orig.)

2005-01-01

This paper introduces the situation, trend of nuclear electrical and uranium industry in the United States and Russia. The United States and Russia are the two biggest countries in the world which generated nuclear power earliest. After 40 years' development, nuclear power in the United States and Russia are approximately 20%, 11% respectively of the total generation capacity in 2001. In the United States, only 6% of the nuclear power consumed uranium resource is domestic, in Russia about half of its uranium production is for export. Due to the collision between the energy development and environment protection, nuclear power in USA is still strong, but the uranium industry declines. In the future, uranium production for nuclear power in the United States will depend on the international market and the uranium storage of different levels. On the basis of pacifying people and making the country prosper, Russia has established their great plans for nuclear power with their substantial uranium resources. The author considers the supply and demand of uranium industry will remain balanced in the future decade on the whole, despite the United States and Russia's trend of uranium industry could take a major effect on uranium industry to the world.

The practice of giving certain authors equal credit in scientific publications has become increasingly common in some medical specialties. However, whether this trend also exists in major spine journals remains unclear. This study aimed to investigate the prevalence and characteristics of the practice of giving authors equal credit in major spine journals. Manual searches were performed to identify original research articles with equally credited authors (ECA) published between January 1, 2004 and December 31, 2013 in three major spine journals: Spine, European Spine Journal, and The Spine Journal. The number of authors with ECA and their positions in the byline, total number of authors, year of publication, and country of origin were analysed. The practice of ECA was found in all three journals. Articles with ECA comprised a greater proportion of the total number of publications in each journal in 2013 versus 2004 (Spine, 7.2 vs. 0.2%; European Spine Journal, 7.5 vs. 0.0%; and The Spine Journal, 6.2 vs. 0.0%). There was a statistically significant increasing trend in the annual proportion of papers with ECA for all three spine journals (p applied in nearly every position in the byline, and the first two authors received equal credit in most cases. Articles with ECA were published by authors from various countries and regions around the world. However, none of the three spine journals provided specific guidance on this practice in their author instructions. The practice of ECA in original research articles is increasingly common in major spine journals. A guideline for authors regarding when and how to designate equal credit is warranted in the future.

2010-01-01

The recent nuclear research issues look for new technologies and continuous progress in finding different and efficient solutions for sustained and upraising energy demand. The trend of increasing energy consumption and occurring of new and large consumers, especially from Asian countries, imposes finding of new means for clean, large scale and sustained energy production. NPPs availability was continuously monitored and improved; at the same time the safety of the nuclear energy production was under surveillance. The present development of the new technologies, the discoveries of new materials and development of efficient technological processes offer the opportunities for their appropriate implementation and use in the NPP system configurations and functioning/operation. The new technologies and scientific discoveries, and also the international cooperation, offer the opportunities to mitigate the actual barriers in order to cumulate and use advanced energy production, to find new energy sources and to build improved, reliable and safe power plants. The monitoring systems, intelligent sensors and SSCs, nanotechnologies and new/intelligent materials constitute the main ways for improvement of the NPP systems configuration and processes. The paper presents: - The state of the art in the level of the currently applied technologies for nuclear power systems development; - The actual technological limits that need to be over passed for improving the NPP systems ; - The main systems that need improvement and reconfiguration for development of currently operating NPPs as well as raising the operation efficiency, availability and total safety; - The actual energy production issues; - The key arguments in sustaining the R and D new NPP systems development; - Future trends in NPP development; - The limitations in industrial processes knowledge and use. Appropriate R and D in the field of NPP systems have specific characteristics that were considered in paper completion

Full Text Available The article focuses on the economic and statistical analysis of industries associated with the use of renewable energy sources in several countries. The dynamic development and implementation of technologies based on renewable energy sources (hereinafter RES is the defining trend of world energy development. The uneven distribution of hydrocarbon reserves, increasing demand of developing countries and environmental risks associated with the production and consumption of fossil resources has led to an increasing interest of many states to this field. Creating low-carbon economies involves the implementation of plans to increase the proportion of clean energy through renewable energy sources, energy efficiency, reduce greenhouse gas emissions. The priority of this sector is a characteristic feature of modern development of developed (USA, EU, Japan and emerging economies (China, India, Brazil, etc., as evidenced by the inclusion of the development of this segment in the state energy strategies and the revision of existing approaches to energy security. The analysis of the use of renewable energy, its contribution to value added of countries-producers is of a particular interest. Over the last decade, the share of energy produced from renewable sources in the energy balances of the world's largest economies increased significantly. Every year the number of power generating capacity based on renewable energy is growing, especially, this trend is apparent in China, USA and European Union countries. There is a significant increase in direct investment in renewable energy. The total investment over the past ten years increased by 5.6 times. The most rapidly developing kinds are solar energy and wind power.

The Recent Development of Croatia's Population – Regular and Irregular Population Trends

Directory of Open Access Journals (Sweden)

Ivan Lajić

2004-09-01

Full Text Available The recent development of Croatia’s population is burdened by many phenomena, due to which we can define it as irregular. Aggression against the newly-independent Croatian state, as well as the wars in its neighbourhood, brought about mechanical population movements that to a great degree enter into the category of forced migrations. The war death rate in the early 1990s and the strong refugee and expellee flows caused the strongest depopulation in recent times. Depopulation was present not only in war-effected areas – its further consequences were felt throughout Croatia. The mechanical, rather than the biological component determined this regressive development. The paper identifies the key modalities in migration flows in Croatia, which show that it is at the same time both an emigration and an immigration country. Wars in former Yugoslavia, which were to a high degree characterized by inter-ethnic conflicts, resulted in migration flows of people to their ethnic core areas. Thus, Croatia has received a strong immigration current made up of Croats from Bosnia and Herzegovina, Serbia and Montenegro, whereas emigration from Croatia to the latter countries mostly involved rural Serbs. Besides these migration trends, members of the ethnically Croatian (majority population and also other groups from Croatia, have migrated to Western Europe, which was a continuation of traditional migration trends. Among these migrants there is a large contingent which could be denoted as part of the “brain drain”. The census conducted in 2001 applied a different methodology than earlier censuses. The problem of different census methodologies is especially pertinent in a country which has a large number of refugees and economic migrants that cannot be classified into the category of emigrants. Thus the 2001 Census registered that Croatia has 4,437,460 inhabitants, or 7.25% less than in 1991.

Reframing E-Government Development Indices with Respect to New Trends in ICT

Full Text Available E-government readiness is an important indicator of the quality of a country’s technological and telecommunication infrastructure and the ability of its citizens, businesses and governments to adopt, use and benefit from modern technologies. To measure and compare selected countries, a lot of benchmarking and ranking indices have been introduced since the beginning of the century. With the increasing importance of trends such as cloud computing, open (big data, participation tools or social media, new indicators and approaches need to be introduced in the measuring of the e-government development, and the existing indices should to be updated, redefined and restructured. Therefore, this article explores the structure of the existing e-government development indices to show the main indicators and trends. Then, it proposes and implements a new framework to evaluate e-government development using these new trends in ICT. It also examines and compares a basic background on the e-government development, benefits and risks of cloud computing, open (big data and participation tools in the public sector. Based on the newly proposed framework, the e-government development index is calculated for each EU Member State to clearly identify the indicators to have an influence on the e-government development. In the last part, these results are compared to the already existing indices to validate the conformity of the rank methods using Kendall rank correlation coefficient.

Full Text Available Nutrition is one of the main factors that have an enormous impact on the health, performance, creativity, activity and life expectancy, as all essential nutrients enter the body is food. Nutrients are transformed by metabolism in the structural elements of the cell, providing the necessary human plastic material and energy. The traditional source of important nutrients for the human body are the pastries, which are in our population is very popular. However, confectionery products is inherent drawback. Excessive consumption of flour confectionery goods violated balanced diets on nutrients and energy value. This is due to a high fat, carbohydrates, and low enough in some cases, complete absence of fiber, minerals and vitamins. In connection with the formation of the system of healthy nutrition of the population requires the development of production technology of confectionery products with the introduction in their structure of functional ingredients, do not change the organoleptic properties of the product, but can help reduce caloric properties of food and the taste of Tatar national. The purpose of this survey – to identify trends in the development of confectionery technology. This review shows that in confectionery production technology to reduce calories and increase the biological value of the replacement trend in the formulations of wheat flour on chickpeas, flax, triticale, sorghum, rice, barley, corn, bird cherry. It is noted that in the recipes for cakes confectionery introduced from non-traditional raw materials containing dietary fiber.

Full Text Available Students in introductory physics courses are likely to have views about physics that differ from those of experts. However, students who continue to study physics eventually become experts themselves. Presumably these students either possess or develop more expertlike views. To investigate this process, the views of introductory physics students majoring in physics are compared with the views of introductory physics students majoring in engineering. In addition, the views of physics majors are assessed at various stages of degree progress. The Colorado learning attitudes about science survey is used to evaluate students’ views about physics, and students’ overall survey scores and responses to individual survey items are analyzed. Beginning physics majors are significantly more expertlike than nonmajors in introductory physics courses, and this high level of sophistication is consistent for most of undergraduate study.

Trends in the energy market after World War II (WW II)

Science.gov (United States)

Swart, K.

1992-01-01

After WW II, trends developed in the energy markets that continued virtually unbroken till 1972. The main trend was the strong growth of oil as a percentage of total energy consumed. Not only did oil monopolise the rapidly growing transportation market but it also penetrated rapidly into the stationary energy market. In the second half of the sixties, after the discovery of the Groningen Gas field, pipeline natural gas took a sizable share of the domestic and commercial energy market in Western Europe. This market was mainly fed by gas from Groningen, the North Sea and Russia. Another trend was the steady growth of electricity as a percentage of the stationary market partly based on nuclear energy. Coal was the loser. This rather steady development was upset by the first oil crisis in 1972. This crisis was a political crisis which had little to do with the physical availability of crude oil. Between 1972 and the present, periods of reasonable price stability were interrupted by violent swings in the price of oil and gas. Moreover, during this period the environmental movement became a major influence in the energy field. Notwithstanding the generally unstable market, some new trends developed after 1972 and some old ones continued. Will these trends continue long enough to be useful for making a scenario for the future? The forecaster should not assume that the development of energy consumption in the USA, Western Europe and Japan will continue to be of overwhelming importance. Developments in South East Asia and Eastern Europe should be watched very carefully. There are reasons to believe that at a certain stage in economic development, transportation demand shoots up much faster than economic growth, leading to a rapid demand growth for distillate oil. Of importance is also how will the rapidly developing countries generate their increasing demand for electricity and how will they fuel their industry? There can be little doubt that in the rich countries

Full Text Available The main goal of this paper is to analyse whether the geopolitical and socio-economic integration and “harmonisation” of the Czech Republic with Western Europe is accompanied by a divergence or convergence of the Czech migratory reality vis-a-vis the developed western world. When testing resemblance two kinds of measurements are used: 1 quantitative – (in terms of the numbers of international migrants, and 2 “qualitative” – a in terms of regularities linked with the migration itself and those that tackle mutual relationships among immigration, the socio-economic development of the destination country and subjective attitudes of the majority population towards minority groups: 3 hypotheses are tested in this regard; b in terms of migratory policies and practices. The results clearly show us that convergence rather than divergence is characteristic of the current migratory trends in the Czech Republic as compared to the developed world, mainly Western Europe.

Deterioration trends of asphalt pavement friction and roughness from medium-term surveys on major Italian roads

Directory of Open Access Journals (Sweden)

Alberti Susanna

2017-09-01

Full Text Available Deterioration models are the key factor for effective Pavement Management Systems, helping out road agencies to assess the actual pavement condition and forecast future performance of the asset. Among pavement condition characteristics, friction should be taken into account due to its important effect on user safety, while roughness could be used to express user comfort. The purpose of this study was to provide a reasonable case study for future improvements of Italian road management, even if the length of the analyzed highways was not intended to be representative of the overall Italian network.This research studied the friction trend (Side Force Coefficient depending on traffic levels (ESALs and pavement aging for Italian highways, combining the data with roughness and macrotexture. Surface characteristics were monitored during a seven-year time span. A selection of different road sections with homogeneous traffic levels, similar environmental conditions and surface material was performed and high-speed/high-quality road surveys were used for distress data collection. Pavement deterioration models for Italian road sectors were developed at project level, as starting point to advance pavement management practices in Italy. Degradation curves showed the same trends for similar pavement structures, materials and traffic levels; on the other hand, differences in pavement characteristics, increased ESALs and various maintenance treatments significantly altered those trends. Keywords: Pavement Management System, Deterioration models, Friction, Roughness, MPD, High-speed monitoring

Full Text Available The article analyzes the development of EU — Russia energy relations through the lens of the evolution of three parameters: the political agenda (the Energy Dialogue, the institutional structure, and the legal modalities. The identification of these three aspects for assessing the evolution of EU — Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU nd Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

Full Text Available One of the key components of the management system is the organizational structure of management. This report presents the current trends of development and improvement of organizational structures of management. The semantics of the term "organizational structure" used in the report is clarified. Key aspects of structural policy of organizations are discussed, as well as the introduction of flexible organizational forms. The main directions for analysis of organizational policy of organizations are also mentioned. It is stressed that the analysis of current trends for the future development of organizational structures of management should be an integral component of the management policy of every organization. The trends are flexibility and adaptability of the organizational structure, rational proportion between centralization and decentralization, an appropriate balance between the rights, duties and responsibilities, reducing regulations, rules and other normative documents. A recommendetaion is made that organizational governance structures must be adapted constantly in accordance with changes in the overall management system, as they are one of its main components.

Trends, demands and challenges in TCAD

International Nuclear Information System (INIS)

Bork, Ingo; Moroz, Victor; Bomholt, Lars; Pramanik, Dipu

2005-01-01

Currently, TCAD is most heavily used in the device research and process integration phases of a technology life cycle. However, a major trend visible in the industry is the demand to apply TCAD tools far beyond the integration phase into manufacturing and yield optimization. Short IC product lifetimes make fast yield ramp-up critical for being profitable and TCAD tools build a bridge between IC design and manufacturing. Another major trend is to use TCAD to evaluate layout dependent stress variations and account for these variations in the design flow of standard cells, libraries and custom ICs. This article gives an overview of those trends and addresses resulting challenges for TCAD models and tools

Trend curve data development and testing

McElroy, W.N.; Gold, R.; Simons, R.L.; Roberts, J.H.

1986-08-01

Existing trend curves do not account for previous and more recently observed test and power reactor flux-level, thermal neutron and gamma-ray field-induced effects. Any agreement between measured data and trend curve predictions that does not adequately represent the important neutron environmental and temperature effects as well as the microstructural damage processes, therefore, could be fortuitous. Two principal questions asked concerning the metallurgical condition of the pressure vessel and its support structures are: What are the controlling variables; and What effects do they have on changing the metallurgical properties of the vessel and its support structures throughout their lifetimes

1998-01-01

For radiology the socioeconomic environment is a topic of increasing importance. In addition to the well-known important scientific developments in radiology such as interventional MRI, several other major trends can be recognized: (1) changes in the delivery of health care, in which all kinds of managed care are developing and will influence the practice of radiology, and (2) the process of computerization and digitization. The socioeconomic environment of radiology will be transformed by the developments in managed care, teleradiology and the integration of information systems. If radiologists want to manage future radiology departments they must have an understanding of the changes in the fields of economics and politics that are taking place and that will increasingly influence radiology. Some important and recognizable aspects of these changes will be described here. (orig.)

Modern trends in theoretical radiation chemistry development

International Nuclear Information System (INIS)

Kaplan, I.G.

1983-01-01

Most important trends in the development of radiation chemitry theory are considered. Wide use of electronic computers for modeling different stages of radiolysis in conjUnction with advanced precision experimental methods (picosecond pulse radiolysis, acceptor additions method, magnetic method of detecting interstitial active particles) is noted. Information obtained in photochemistry and molecular spectroscopy, including laser photolysis, is in common use in developing the theory. It is noted that data on the processes occurring within less than 10 -12 s time can be obtained now only on the base of theoretical representations about the mechanism of ionizing irradiation interaction with molecular medium. Therefore, special attention in the review is paid to investigation of primary radiolysis processes. Besides investigation of primary medium excitation processes theoretical investigations into the ways of energy degradation, knocked out electrons and their further state are continued. It is noted that a considerable number of papers deal with the nature and behaviour of radiation-induced excess electrons in non-polar solutions and solid matrices. Works on application of diffusion kinetics in radiolysis have been developed in recent years

Medical tourism market trends - an exploratory research

2017-07-01

Full Text Available Medical tourism is a modern concept, but not a new tourism practice. Even there is still no international consent on the definitions and measurement of this trend, its importance in the development of a tourism destination started to be taken into consideration. In accordance with tourism segment classification depending on journey reasons recommended by World Tourism Organization, one of the main groups is for “medical treatment/health”. Being part of health tourism, medical tourism is often called medical travel because it includes the act of travelling to different countries for medical reasons. An increasing significant element in medical service trade is patient circulation at cross-border level with a view to obtaining necessary health services; this circulation generated a new phenomenon, namely medical tourism. Studying the scientific literature we find new medical tourism trends in connection with globalization and liberalization. The countries that decided to promote this niche tourism are aware of the huge economic benefits brought by this. Analyzing published data by tourism medical organizations associated to indicators of economic development, we find two aspects: the success of a medical tourism destination is influenced by the economical level of the receiving countries, but, at the same time, it is also a growth factor for developing economies if it is included in their national strategy. We intend to find the answer of several questions: trends in medical tourism development are involving only medical service trade, or a combination of specific activities of many sectors? Is the medical tourism acting in favor of developing economies? This study aims to notice the development trends of the medical tourism based on the published figures and on the experience of major destinations and to highlight the importance of the medical tourism for the developing economies.

Voigt, Sebastian; De Cian, Enrica; Schymura, Michael; Verdolini, Elena

2014-01-01

This study analyzes energy intensity trends and drivers in 40 major economies using the WIOD database, a novel harmonized and consistent dataset of input–output table time series accompanied by environmental satellite data. We use logarithmic mean Divisia index decomposition to (1) attribute efficiency changes to either changes in technology or changes in the structure of the economy, (2) study trends in global energy intensity between 1995 and 2007, and (3) highlight sectoral and regional differences. For the country analysis we apply the traditional two factor index decomposition approach, while for the global analysis we use a three factor decomposition which includes the consideration of regional structural changes in the global economy. We first show that heterogeneity within each sector across countries is high. These general trends within sectors are dominated by large economies, first and foremost the United States. In most cases, heterogeneity is lower within each country across the different sectors. Regarding changes of energy intensity at the country level, improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries. Notable exceptions are Japan, the United States, Australia, Taiwan, Mexico and Brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction. At the global level we find that despite a shift of the global economy to more energy-intensive countries, aggregate energy efficiency improved mostly due to technological change

Trends and temporal variations of major greenhouse gases at a rural site in Central Europe

Science.gov (United States)

Haszpra, L.; Barcza, Z.; Hidy, D.; Szilágyi, I.; Dlugokencky, E.; Tans, P.

In this study the trends and temporal variations of four major greenhouse gases (CO 2, CH 4, N 2O, SF 6) measured at Hegyhátsál, Hungary, are analyzed. The long term trends observed closely follow the global tendencies. The relatively small positive offset can be attributed to the European anthropogenic sources. The seasonal cycles are basically governed by that in the atmospheric mixing, however, in the case of CO 2 and N 2O it is also modulated by the temporal variation in the biological activity. A secondary maximum in SF 6 mixing ratio in summer may indicate the additional contribution of the seasonally changing circulation pattern. The daily cycles are dominated by the diurnal variation in the vertical mixing of the atmosphere. However, in the case of CO 2 the diurnal cycle in the biospheric uptake/release is the governing process, especially in the growing season. The lack of diurnal cycle in the mixing ratio of the exclusively anthropogenic SF 6 indicates that there is no notable anthropogenic activity in the influence area of the station, which also means that Hegyhátsál can be considered to be a rural monitoring site as free from direct anthropogenic pollution as it is possible in Central Europe. It is demonstrated that the diurnal covariance between the mixing ratios and the vertical mixing at a mid-continental, low elevation site has to be taken into account, and properly handled, in the dispersion models, otherwise the results may be distorted. The collocated measurement of greenhouse gases of different origin could potentially help modelers to improve the boundary layer representation and horizontal diffusion simulation in the three dimensional atmospheric transport models.

Trends in the development of equipment for anaerobic fermentation

Energy Technology Data Exchange (ETDEWEB)

Holcak, B; Lutcha, J

1982-01-01

The successful application of anaerobic fermentation to the utilization of diluted wastes for the production of energy stimulated in recent years the development of new types of anaerobic reactors. Although the point of view of a chemical engineer does not encompass the complexity of this microbial process, he still disposes of means that enable him to estimate to what extent is it possible to affect the efficiency of the process by the concept of reactor arrangement. Simulation of behaviour by means of mathematical models enables us to compare quantitatively, for the types of anaerobic reactor under consideration, the apparatuses, and to predict the expected trends in their development.

Over the past 15 years, scientists and disaster responders have increasingly used satellite-based Earth observations for global rapid assessment of disaster situations. We review global trends in satellite rapid response and emergency mapping from 2000 to 2014, analyzing more than 1000 incidents in which satellite monitoring was used for assessing major disaster situations. We provide a synthesis of spatial patterns and temporal trends in global satellite emergency mapping efforts and show that satellite-based emergency mapping is most intensively deployed in Asia and Europe and follows well the geographic, physical, and temporal distributions of global natural disasters. We present an outlook on the future use of Earth observation technology for disaster response and mitigation by putting past and current developments into context and perspective.

Long term trending of engineering data for the Hubble Space Telescope

Science.gov (United States)

Cox, Ross M.

1993-01-01

A major goal in spacecraft engineering analysis is the detection of component failures before the fact. Trending is the process of monitoring subsystem states to discern unusual behaviors. This involves reducing vast amounts of data about a component or subsystem into a form that helps humans discern underlying patterns and correlations. A long term trending system has been developed for the Hubble Space Telescope. Besides processing the data for 988 distinct telemetry measurements each day, it produces plots of 477 important parameters for the entire 24 hours. Daily updates to the trend files also produce 339 thirty day trend plots each month. The total system combines command procedures to control the execution of the C-based data processing program, user-written FORTRAN routines, and commercial off-the-shelf plotting software. This paper includes a discussion the performance of the trending system and of its limitations.

Review of trends in computerized systems for operator support

International Nuclear Information System (INIS)

Cain, D.G.

1985-01-01

The major trends shaping the development of computerized operator support systems in nuclear power plants are reviewed. These trends are the result of prior research in disturbance analysis systems that provided the technology base, and the SPDS requirement, which has been the impetus for change. The process is expected to result in hybrid control rooms with computer-driven supervisory workstations that complement conventional control board lay-outs. In the next three to five year period substantial upgrading of computer hardware will allow new and more sophisticated applications routines to be developed for operator support. Greater attention is being given to on-line validation of input signals for computer applications. A general movement towards operating strategies that are not based upon pre-analyzed event sequences is expected to influence the development of operator aids. The integration of displays with operating procedures will enable the computer system to a better coupling between problem detection and its resolution. Improved design methodology will assure that computer applications are accepted and used by operations personnel. Greater on-line analysis capability is stimulating the trend towards more on-site analysis and decision-making at nuclear power plants. Software standardization reflects the high cost of software development and the desire by utilities to gain greater independence from suppliers. There is growing realization that control rooms are beset by many of the demands and limitations of other office settings and that some of these may be addressed by the burgeoning office automation technology. Trends beyond the next five years are difficult to predict; however, there will be a trend towards more intelligent software. Artificial intelligence technology may play a pivotal role in future applications. Taking these trends into perspective, the author concludes that a promising future exists for computerized operator support in nuclear

Full Text Available The article discusses the key trends shaping the international regime on information security. International cooperation in this area at the global level encounters contradictions of state interest. The main actors of the information security are the United States, Russia, China and the EU countries (Britain, France and Germany. The main contradiction is developing between the US on one side and Russia and China on the other. EU countries occupy the middle position, gravitating to that of US. The article proves that international cooperation on information security will reflect the overall logic of the development of international cooperation, which is characterized by a new model of cooperation, with the participation of state and non-state actors, known as multi-stakeholder partnerships and multi-level cooperation. The logic of the formation of an international regime on information security is closest to the logic of the formation of the international non-proliferation regime. It is in the interest of Russia to support the trend towards regionalization of information security regime. Russia can form a regional information security regime in the former Soviet Union on the basis of the CSTO and SCO and potentially on a wider Eurasian space. Such regional regime would give Russia an opportunity to shape the international regime and closely monitor emerging information security issues in the former Soviet Union, and remove the potential threat of "color revolutions".

Full Text Available The international collaboration is entering the new era of globalization revealing not only the new ways of development and quantum growth for humanity but also new threats, problems and global conflicts. There is now doubt that humanity is facing new global range of problems, agenda of the 21st century and urgent issues of global organization of the world order and systems of global administration acceptable for all states. Preventing distribution of international confrontation between the major political players through advancement of separatist and terrorist trends must become the main priority for the international system of collective security, which should be changed according to the realities of the modern global processes.

Provencal, Simon; Kishcha, Pavel; Elhacham, Emily; daSilva, Arlindo M.; Alpert, Pinhas; Suarez, Max J.

2014-01-01

NASA's Global Modeling and Assimilation Office has extended the Modern-Era Retrospective Analysis for Research and Application (MERRA) tool with five atmospheric aerosol species (sulfates, organic carbon, black carbon, mineral dust and sea salt). This inclusion of aerosol reanalysis data is now known as MERRAero. This study analyses a ten-year period (July 2002 - June 2012) MERRAero aerosol reanalysis applied to the study of aerosol optical depth (AOD) and its trends for the aforementioned aerosol species over the world's major cities (with a population of over 2 million inhabitants). We found that a proportion of various aerosol species in total AOD exhibited a geographical dependence. Cities in industrialized regions (North America, Europe, central and eastern Asia) are characterized by a strong proportion of sulfate aerosols. Organic carbon aerosols are dominant over cities which are located in regions where biomass burning frequently occurs (South America and southern Africa). Mineral dust dominates other aerosol species in cities located in proximity to the major deserts (northern Africa and western Asia). Sea salt aerosols are prominent in coastal cities but are dominant aerosol species in very few of them. AOD trends are declining over cities in North America, Europe and Japan, as a result of effective air quality regulation. By contrast, the economic boom in China and India has led to increasing AOD trends over most cities in these two highly-populated countries. Increasing AOD trends over cities in the Middle East are caused by increasing desert dust.

The current trends in radioisotope and radiation technology in the United States are overviewed with emphasis on the developments since the 1973 Conference. The comments focus primarily on the research and development activities receiving the most attention today from the various agencies of the Government. Among the many available radionuclides, technetium-99m has played the single most important role for making possible the developments in the field of nuclear medicine. Many other short lived medium-lived nuclides are applied in the fields of nuclear medicine, cardiac pacemaker, artificial heart, and blood irradiator. Radiation processing is now firmly established in the United States. The trends in sewage treatment, polymer-impregnated materials, bioengineering, and food irradiation are reviewed. The programs for californium-252, strontium-90, cesium-137, plutonium-238, and krypton-85 are also reviewed. The author concludes this paper with the acknowledgement that Japanese researchers have contributed to and have been closely involved in many of the programs discussed. Of particular note is the participation in the clinical phase of the californium-252 radiotherapy program. Several Japanese hospitals have been cooperating with the United States since the very beginning of the californium-252 program in determining the value of the californium-252 neutron therapy. The research being performed is unique, and will contribute greatly to the decisions on the ultimate future of californium-252 for therapeutic purposes.

Full Text Available Cereal crops have played major roles in addressing food security issues in Nepal. In recent years there have been fluctuations in crop production and demands situations due to various reasons. Thus, the present study aims to analyze the dynamics of major cereals productivity in Nepal from 1995 to 2014. Focus group discussions were done in mid-hills and tarai of Nepal in 2015. Percentage change, compound growth rate, annual rate of change, coefficient of variation, instability index were calculated to analyze results. The result shows that the area, production and productivity of major cereals had an increasing trend over the study period. The major factors contributing on productivity increase in cereal crops were irrigation facilities, use of improved and hybrid seeds, chemical fertilizer and better technical knowhow among the farmers. For effective adoption of research outputs to improve the productivity emphasis should also be given on promotion of public private partnership (PPP in research and development.

What the Current System Development Trends tell us about Systems Development Methodologies: Toward explaining SSDAM, Agile and IDEF0 Methodologies

Directory of Open Access Journals (Sweden)

Abdulla F. Ally

2015-03-01

Full Text Available Systems integration, customization and component based development approach are of increasing attention. This trend facilitates the research attention to also focus on systems development methodologies. The availability of systems development tools, rapid change in technologies, evolution of mobile computing and the growth of cloud computing have necessitated a move toward systems integration and customization rather than developing systems from scratch. This tendency encourages component based development and discourages traditional systems development approach. The paper presents and evaluates SSADM, IDEF0 and Agile systems development methodologies. More specifically, it examines how they fit or not fit into the current competitive market of systems development. In the view of this perspective, it is anticipated that despite of its popularity, SSADM methodology is becoming obsolete while Agile and IDEF0 methodologies are still gaining acceptance in the current competitive market of systems development. The present study more likely enrich our understanding of the systems development methodologies concepts and draw attention regarding where the current trends in system development are heading.

Regional trend of coal metamorphism in the major Gondwana basins of India

Energy Technology Data Exchange (ETDEWEB)

Mukherjee, A K; Alam, M M; Bunerjee, B

1983-04-01

The coal-bearing Gondwana sedimentaries are of great economic importance as they possess over 98% of coal resources of India. Within the Gondwana supergroup coal-bearing formations are confined in the Lower Gondwana sequence (Damuda group). The development of coal seams in the different basins were genetically related to the evolutionary pattern of each basin. The imprint of such diverse tectono-geomorphic conditions prevailing over the vast Peninsular Shield, and their regional impact in individual basins are well preserved in the different lithofacies of this thick-pile of sedimentary sequence. In fact constituting coal facies served as a sensitive recorder of the past episode enacted for long geological time span in each basin of the Gondwana grabens. In the present paper an attempt is made to incorporate the salient features of the operative processes in the major Gondwana basins with special reference to coal metamorphism. This has been done considering mass of analytical and sub-surface data available from the physico-chemical survey of coal seams of major coalfields, and extensive drilling operations carried out over the vast virgin tracts of important coalfields.

We investigated temporal trends in BMI, and assessed hypothesized predictors of trends including socio-economic position (SEP) and province-level economic development, in Argentina. Using multivariable linear regression, we evaluated cross-sectional patterning and temporal trends in BMI and examined heterogeneity in these associations by SEP and province-level economic development with nationally representative samples from Argentina in 2005 and 2009. We calculated mean annual changes in BMI for men and women to assess secular trends. Women, but not men, exhibited a strong cross-sectional inverse association between SEP and BMI, with the lowest-SEP women having an average BMI 2.55 kg/m(2) greater than the highest-SEP women. Analysis of trends revealed a mean annual increase in BMI of 0.19 kg/m(2) and 0.15 kg/m(2) for women and men, respectively, with slightly greater increases occurring in provinces with greater economic growth. No significant heterogeneity in trends existed by individual SEP. BMI is increasing rapidly over time in Argentina irrespective of various sociodemographic characteristics. Higher BMI remains more common in women of lower SEP compared with those of higher SEP.

Full Text Available The article constitutes an attempt to identify current tendencies regarding the development of unmanned marine technologies such as unmanned surface and underwater vehicles. The analyses were performed on the basis of available literature, databases on research projects and internet sources. The material has been divided with regard to the location the research was conducted, the following groups being identified: the European Union, the United States of America and Poland. On the basis of the review of objectives and final effects of projects, tendencies in the development of the discussed marine technology have been identified. An interesting result of the review consists in an observation that Polish R&D works in this area are placed within the main identified developmental trends. Unfortunately, their effects are incomparable due to the minuteness of national funds allocated to R&D as opposed to other countries.

Full Text Available The article is devoted to the actual subject - features development of tourism in Ukraine. Tourism in Ukraine legally declared as a priority of national culture and economy. The promotion of Ukraine as a European state requires the development of tourism industry. The modern concept of leisure activities organization leads to increased demand for tourism in those regions, which have the cultural, social, household identity of the nation, local community. These areas are presented in the most regions of Ukraine. Due to the wealth of historical, cultural, recreational, social and economic resources Ukraine has all essential prerequisites for intensive tourism development. Tourism plays an important role in regional development. Currently, most researches are aimed at economic aspects of development, which are usually associated with external (international tourism. However not enough attention were paid to social and environmental aspects of domestic tourism, which may become an important tool for spiritual revival, patriotic education, formation of ecological thinking and future mentality of the Ukrainian society. In the development of tourism in Ukraine there are some features: changing in the ratio of internal and external tourism in favor of external, a small number of foreign tourists, the gradual reduction in the number of citizens covered by domestic tourism. In 2015 the tourist flow was at the level of 2000 and amounted into 2,02 million people. There was a reduction compared to 2013 by almost 40%. Although the highest rates of reduction (30% occurred in 2014, and 10% - in 2015. So the rate of decrease in tourist flow slowed. The number of foreign tourists significantly reduced to a record 0.75% of the total number of travelers. On the contrary, the number of citizens of Ukraine, which travelled abroad remains very high and exceeds 80%. The number of domestic tourists remains at the level of 17%. Unfortunately, the negative trends in

2006-01-01

The paper presents the current trends of nuclear energy in Europe, the issue of radioactive waste management, the modern technical solutions for building new nuclear power plants and, also, the nuclear power long term prospects. The following trends and methods of reducing costs are addressed: - upgrading the availability of nuclear power units; since 1990 till now in Europe the availability factor has risen from 74 % to 84%; - extending the operation life of nuclear power plants from 30 - 40 years to 60 years; - stable reduction of the duration of annual planned outages necessary for maintenance and nuclear fuel re-loading; it is noteworthy the performance of Unit 2 Olkiluoto NPP, Finland, that was shutdown for annual outage and fuel re-loading for a 7 days only; - stable cuts of nuclear fuel cost by using advanced nuclear fuel and by increasing the fuel burnup; over the last years, nuclear fuel cost share in the operation costs has constantly decreased to values of about 0.5 USD cent/KWh e; - increase of the rated capacity of the existing in Europe nuclear power units, through upgrading programs that contribute to enhancing their efficiency. In the year 2002 Generation IV International Forum (GIF) finalized the technological strategy in the field, identifying the most promising nuclear power systems for which the research will continue. This strategy also identifies the main objectives that must by pursued within the research-development programs out of which one mentions the following: - identifying sustainable solution for generating electricity; - minimizing the radioactive waste and its management; - optimization of operation costs; - reducing the financial risk comparable to other energy solutions; - excellence in nuclear safety and reliability; - increasing resistance to proliferation; - ruling out the emergency solutions. Finally, the paper mentions the international engagement, representing a new approach in nuclear power, namely the transition to the use

It would be a truism to say that the trends in the area of proliferation display positive and negative aspects. On the one hand, the steps being taken by the nuclear haves appear to be designed to maintain their nuclear hegemony forever; on the other, there are indications such as the support being extended to the proposed conventions for the ending of nuclear tests and the production of fissile material for weapons that the nuclear weapons states also realize that the problem cannot be solved unless they also participate in the process and accept non-discriminatory restraints. However, it is much too early to predict which way the situation will develop. (author). 34 refs

[Regional differences in the development of hospitalizations : An effect of different demographic trends?

Science.gov (United States)

Nowossadeck, Enno; Prütz, Franziska

2018-03-01

Population aging and population decline in many regions of the Federal Republic of Germany are key elements of demographic change. In the regions concerned there is a rising number of older people and, simultaneously, a declining population. So far, the consequences of regional shrinkage and growth for inpatient care don't seem to have been analysed very well. This paper analyses the influence of population aging and declining/increasing population (demographic factors) as well as other, non-demographic factors on the number of hospitalizations in Germany and the Federal States since 2000.One result of the analysis is that there are major differences between the Federal States. The analysis shows, for example, an increase of hospitalizations in Berlin while in Saxony-Anhalt the number of hospitalizations declines. The increase in Berlin was the result of population aging and, to a lower extent, an increase in population. In Saxony-Anhalt the declining population resulted in a decreasing number of hospitalizations. Population aging and non-demographic factors were not able to compensate this trend.Overall, the effect of demographic factors on the number of hospitalizations remains constant over time. Short-term changes of hospitalizations are due to non-demographic factors, such as epidemiological trends, (for example trends of incidence or prevalence), or structural changes of health care service (for example patients shifting between different sectors of health care or the introduction of new reimbursement systems).

Diabetes mellitus is a major health problem in developing countries. There are various insulin therapies to manage diabetes mellitus. This systematic review evaluates various insulin therapies for management of diabetes mellitus worldwide. This review also focuses on recent developments being explored for better management of diabetes mellitus. We reviewed a number of published articles from 2002 to 2016 to find out the appropriate management of diabetes mellitus. The paramount parameters of the selected studies include the insulin type & its dose, type of diabetes, duration and comparison of different insulin protocols. In addition, various newly developed approaches for insulin delivery with potential output have also been evaluated. A great variability was observed in managing diabetes mellitus through insulin therapy and the important controlling factors found for this therapy include; dose titration, duration of insulin use, type of insulin used and combination therapy of different insulin. A range of research articles on current trends and recent advances in insulin has been summarized, which led us to the conclusion that multiple daily insulin injections or continuous subcutaneous insulin infusion (insulin pump) is the best method to manage diabetes mellitus. In future perspectives, development of the oral and inhalant insulin would be a tremendous breakthrough in Insulin therapy. Copyright © 2017 Diabetes India. Published by Elsevier Ltd.

Impacts of Global Manufacturing Trends on Port Development: The Case of Hong Kong1

Directory of Open Access Journals (Sweden)

Abraham Zhang

2015-03-01

Full Text Available Global manufacturing trends may have profound implications for regional port development. This paper studies Hong Kong port (HKP, which has been one of the world's busiest container ports since the 1990s. In recent years, global manufacturers have started to move away from its primary cargo base, the Chinese Pearl River Delta. This study investigates impacts of the emerging global manufacturing trends on HKP development. It is found that relocation of manufacturing to Western Guangdong benefits HKP, while other relocation destinations make HKP less attractive or even irrelevant. Based on the findings, government policies are discussed that may be formulated to support the growth of the port and wider port-related economy.

A minority of panelists concluded that the current data on girls' puberty timing for any marker...... are insufficient. Almost all panelists concluded, on the basis of few studies and reliability issues of some male puberty markers, that current data for boys are insufficient to evaluate secular trends in male pubertal development. The panel agreed that altered puberty timing should be considered an adverse effect......Whether children, especially girls, are entering and progressing through puberty earlier today than in the mid-1900s has been debated. Secular trend analysis, based on available data, is limited by data comparability among studies in different populations, in different periods of time, and using...

To analyze the trends and developments among journals in the specialty of obstetrics and gynecology. Using the Journal Citation Reports from 2007 to 2013, we analyzed the impact factor (IF), Eigenfactor® Score (ES), and Article Influence® Score (AIS) of 43 journals in the field of obstetrics and gynecology published in this time period. From 78 journals of the Journal Citation Report 2013, 43 were selected for this study. The mean IF grew from 1.68 ± 0.97 in 2007 to 2.12 ± 1.05 in 2013, the ES from 0.0113 ± 0.0169 to 0.0114 ± 0.0140, and the AIS from 0.513 ± 0.302 to 0.663 ± 0.359. Differences in the IF, ES, and AIS between journals from the United States versus Europe could be observed. In most cases, the IF, ES, and AIS increased between 2007 and 2013. Strong correlations could be found between IF, AIS, and ES. The overall mean IF for obstetrical and gynecological journals increased over the analyzed time period. The IF remains the standard measure to compare scientific journals. It correlates well with two major alternative measures of scientific impact, the ES and especially the AIS. Other measures are evolving and might show superior usage in the future.

Secular trends in menarcheal age in India-evidence from the Indian human development survey.

Directory of Open Access Journals (Sweden)

Praveen Kumar Pathak

Full Text Available Evidence from a number of countries in Europe and North America point towards the secular declining trend in menarcheal age with considerable spatial variations over the past two centuries. Similar trends were reported in several developing countries from Asia, Africa and Latin America. However, data corroborating any secular trend in the menarcheal age of the Indian population remained sparse and inadequately verified.We examined secular trends, regional heterogeneity and association of socioeconomic, anthropometric and contextual factors with menarcheal age among ever-married women (15-49 years in India. Using the pseudo cohort data approach, we fit multiple linear regression models to estimate secular trends in menarcheal age of 91394 ever-married women using the Indian Human Development Survey.The mean age at menarche among Indian women was 13.76 years (95 % CI: 13.75, 13.77 in 2005. It declined by three months from 13.83 years (95% CI: 13.81, 13.85 among women born prior to 1955-1964, to nearly 13.62 years (95% CI: 13.58, 13.67 among women born during late 1985-1989. However, these aggregate national figures mask extensive spatial heterogeneity as mean age at menarche varied from 15.0 years in Himachal Pradesh during 1955-1964 (95% CI: 14.89-15.11 to about 12.1 years in Assam (95% CI: 11.63-12.56 during 1985-1989.The regression analysis established a reduction of nearly one month per decade, suggesting a secular decline in age at menarche among Indian women. Notably, the menarcheal age was significantly associated with the area of residence, geographic region, linguistic groups, educational attainment, wealth status, caste and religious affiliations among Indian women.

As a result of the global economic crisis since the end of 2008, HCK operators have been looking to increase the profitability of the unit by processing heavier feed streams, including sourer VGO. These feeds present the drawbacks of increased H{sub 2} consumption, lower products yields and quality, and reduction in cycle lengths. Along with optimised process parameters, catalysts manufacturers are also investigating novel formulations to deal with challenging feeds. This lecture briefly summarizes the market trends (fuel demand, refinery's product specification) and the driving forces for HCK catalyst development in order to face these new challenges. Finally, this lecture highlights the innovating trends for HCK catalyst's development. Overview of various ideas developed recently in our research laboratory about (i) rational approaches for the atomic scale design of active phases (morphology, preparation, inhibitor effects), (ii) new preparations of transition metal sulphides for maximising the hydrogenating function (precursors, activation,.), (iii) rational approaches of HCK acidic supports for maximizing the selectivity and (iv) better understanding of HCK reactions. These improvements will be discussed in term of improvement of activity and selectivity of HCK catalyst to cope with future market needs. (orig.)

MacKenzie, Meagan B; Kocovski, Nancy L

2016-01-01

Mindfulness-based cognitive therapy (MBCT) was developed as a psychological intervention for individuals at risk of depressive relapse. Possible mechanisms of change for this intervention are in line with its theoretical underpinnings, and include increases in mindfulness and/or decreases in negative repetitive thoughts. This review provides an overview of current trends in MBCT research, including efficacy and questions regarding the specific effects of MBCT in light of recent comparisons with structurally equivalent control conditions, mechanisms of change, and moderators of treatment outcome. In addition, future directions are discussed, such as challenges with training an adequate number of therapists and disseminating this therapy.

Trends in water quality and quantity were assessed for 11 major reservoirs of the Brazos and Colorado river basins in the southern Great Plains (maximum period of record, 1965–2010). Water quality, major contributing-stream inflow, storage, local precipitation, and basin-wide total water withdrawals were analyzed. Inflow and storage decreased and total phosphorus increased in most reservoirs. The overall, warmest-, or coldest-monthly temperatures increased in 7 reservoirs, decreased in 1 reservoir, and did not significantly change in 3 reservoirs. The most common monotonic trend in salinity-related variables (specific conductance, chloride, sulfate) was one of no change, and when significant change occurred, it was inconsistent among reservoirs. No significant change was detected in monthly sums of local precipitation. Annual water withdrawals increased in both basins, but the increase was significant (P < 0.05) only in the Colorado River and marginally significant (P < 0.1) in the Brazos River. Salinity-related variables dominated spatial variability in water quality data due to the presence of high- and low-salinity reservoirs in both basins. These observations present a landscape in the Brazos and Colorado river basins where, in the last ∼40 years, reservoir inflow and storage generally decreased, eutrophication generally increased, and water temperature generally increased in at least 1 of 3 temperature indicators evaluated. Because local precipitation remained generally stable, observed reductions in reservoir inflow and storage during the study period may be attributable to other proximate factors, including increased water withdrawals (at least in the Colorado River basin) or decreased runoff from contributing watersheds.

The Trend of Women in Nuclear Security in Zimbabwe

International Nuclear Information System (INIS)

Sithole, P.; Chipuru, J.

2015-01-01

With the increase in the use of radiation technologies, each country now has a potential risk from nuclear related offenses or malicious use of radioactive material. Despite the major advancements women have made in becoming a significant part of the workforce in all the other fields, women in the field of Nuclear Security are underrepresented in Zimbabwe. Nuclear security contributes to global security and there are a number of things that constitute this field. In the past 10 years, in developing countries, a few women have been taking part in Nuclear Security activities at Major Public events. Less than 1% of women in Zimbabwe are employed and take part in Nuclear Security related work. This study provides the trend in statistics of women employed in the field of Nuclear Security in Zimbabwe and it has identified possible factors why women are underrepresented in that field. It shows the trend of women taking part in Nuclear Security related activities for the past 10 years. Women’s experiences of employment and career development in nuclear security were studied. The factors which hinder or support the career development of women employees in Nuclear Security or related work were identified. Practices which encourage and support women’s involvement in Nuclear Security were explored. A statistical analysis of local authority employment, using the Ministry of Labour, census of women in science and nuclear security related studies in the Population of Zimbabwe, and other relevant sources was carried out. This was to describe the wider context of women’s employment in Nuclear Security. A self-completion questionnaire to get information on personal attributes, age and preferred career paths for women was used. Solutions to the trend are suggested in the study. (author)

Full Text Available Oil processing was considered as slowly changing “traditional” industry but the recent decades’ developments and trends resulted in a lot of changes initiated by market, industry, environment protection and consumer needs. Driving force of the developments were centralization of the industry, more and more concerns on environmental impact, increased importance of food-feed safety, and last but not least research and development activity together with improved analytical capabilities. The presentation gives an overview on the results achieved on the field of the following areas: the criteria of applicability of physical refining of seed oils, solutions for proper degumming, the effect of seed pretreatment and crushing conditions on the crude oil quality, the importance and role of bleaching and active carbon treatment, the proper practice of deacidification/deodorization.

Trend analysis

International Nuclear Information System (INIS)

Smith, M.; Jones, D.R.

The goal of exploration is to find reserves that will earn an adequate rate of return on the capital invested. Neither exploration nor economics is an exact science. The authors must therefore explore in those trends (plays) that have the highest probability of achieving this goal. Trend analysis is a technique for organizing the available data to make these strategic exploration decisions objectively and is in conformance with their goals and risk attitudes. Trend analysis differs from resource estimation in its purpose. It seeks to determine the probability of economic success for an exploration program, not the ultimate results of the total industry effort. Thus the recent past is assumed to be the best estimate of the exploration probabilities for the near future. This information is combined with economic forecasts. The computer software tools necessary for trend analysis are (1) Information data base - requirements and sources. (2) Data conditioning program - assignment to trends, correction of errors, and conversion into usable form. (3) Statistical processing program - calculation of probability of success and discovery size probability distribution. (4) Analytical processing - Monte Carlo simulation to develop the probability distribution of the economic return/investment ratio for a trend. Limited capital (short-run) effects are analyzed using the Gambler's Ruin concept in the Monte Carlo simulation and by a short-cut method. Multiple trend analysis is concerned with comparing and ranking trends, allocating funds among acceptable trends, and characterizing program risk by using risk profiles. In summary, trend analysis is a reality check for long-range exploration planning

Modern Trends in the Development of Business Technologies in Entrepreneurship

Directory of Open Access Journals (Sweden)

Dudko Pavlo M.

2017-09-01

Full Text Available The aim of the article is to study modern trends in the development of business technologies and their integration into entrepreneurship. Business technologies are a combination of methods, techniques, innovations, technical and mental solutions that promote development of business, expand its capabilities and create new prospects for it. The main business technologies that are widely used in entrepreneurship and have gained worldwide recognition include franchising, leasing, outsourcing, cashback, clustering. Due to the rapid development of information technologies and the Internet, such business technologies as e-commerce, IT outsourcing, offshore programming, crowdsourcing and the CRM strategy have emerged. At the same time, business technologies develop independently and without using modern technical innovations, an example of which is co-marketing. Summarizing, it can be noted that business technologies are not only the existing methods of business development but also a constant and dynamic search for new solutions in entrepreneurship. The development and improvement of the existing business technologies, as well as the emergence of new ones, directly depends on the technological progress and development of mankind.

New trends and developments in radiation chemistry

International Nuclear Information System (INIS)

1989-10-01

Radiation chemistry is a branch of chemistry that studies chemical transformations in materials exposed to high-energy radiations. It uses radiation as the initiator of chemical reactions. Practical applications of radiation chemistry today extend to many fields, including health care, food and agriculture, manufacturing, industrial pollution abatement, biotechnology and telecommunications. The important advantage of radiation chemistry lies in its ability to be used to produce, and study, almost any reactive atomic and molecular species playing a part in chemical reactions, synthesis, industrial processes, or in biological systems. The techniques are applicable to gaseous, liquid, solid, and heterogeneous systems. By combining different techniques of radiation chemistry with analytical chemistry, the reaction mechanism and kinetics of chemical reactions are studied. In November 1988 in Bologna, Italy, the IAEA convened an advisory group meeting to assess new trends and developments in radiation chemistry. The present publication includes most of the contributions presented at the meeting. Refs, figs and tabs

Daily gridded high-resolution rainfall data of India Meteorological Department at 0.25° spatial resolution (1901-2015) was analyzed to detect the trend in seasonal, annual, and maximum cumulative rainfall for 1, 2, 3, and 5 days. The present study was carried out for 85 river basins of India during 1901-2015 and pre- and post-urbanization era, i.e., 1901-1970 and 1971-2015, respectively. Mann-Kendall ( α = 0.05) and Theil-Sen's tests were employed for detecting the trend and percentage of change over the period of time, respectively. Daily extreme rainfall events, above 95 and 99 percentile threshold, were also analyzed to detect any trend in their magnitude and number of occurrences. The upward trend was found for the majority of the sub-basins for 1-, 2-, 3-, and 5-day maximum cumulative rainfall during the post-urbanization era. The magnitude of extreme threshold events is also found to be increasing in the majority of the river basins during the post-urbanization era. A 30-year moving window analysis further revealed a widespread upward trend in a number of extreme threshold rainfall events possibly due to urbanization and climatic factors. Overall trends studied against intra-basin trend across Ganga basin reveal the mixed pattern of trends due to inherent spatial heterogeneity of rainfall, therefore, highlighting the importance of scale for such studies.

Sousa, David

This article compares the results of two surveys sent to New Jersey science supervisors in 1978 and 1982 regarding the status of secondary science education in their schools. It discusses trends that have developed during the four-year period and compares them to national trends revealed in recent studies. The comparison shows that New Jersey faces many of the same problems in science education found across the country. Instruction time in science, double laboratory periods, and the use of national curriculum studies have all declined. Respondents also reported a marked increase in the number of science teachers leaving the classroom for jobs in business and industry. The recruiting of qualified teachers was a difficult task and over 9% of the public schools reported having to use teachers with emergency certification in science to meet their staffing requirements. Difficulties in using staff effectively, in obtaining adequate financial support, and in providing professional development programs were the major concerns of science supervisors.Received: 12 April 1983

Hydropower development trends from a technological paradigm perspective

Xu, Jiuping; Ni, Ting; Zheng, Bobo

2015-01-01

Highlights: • We propose a novel concept of hydropower development technological paradigm. • We create a data analysis system to visualize the keyword foci. • Future trajectories include hybrid power systems and resources from seawater. • The HDTP consists of a three-stage evolution and a policy framework. • The HDTP provides a how-to-do solution for the soft path. - Abstract: Hydropower has long been considered the backbone of the power generation sector in low-carbon and sustainable energy systems. Yet, as reliance on hydropower has been generally declining, the world is awakening to the need to fundamentally rethink the way hydropower is developed and managed. The paper proposes a systematic methodology to research the development trends and find a more sustainable hydropower path. Literature mining using the data analysis system and the technological paradigm theory were adopted to conduct the research. The keyword visualization results were found to meet the laws for the three phases of the technological paradigm. Specific key areas, such as small hydropower plants, hybrid power systems, and hydropower from seawater were identified as past, present and near future trajectories. To further accelerate hydropower development, specific subsidies and incentives need to be provided in areas such as capital costs and technological support. The study paves the way for a soft path solution which complements the hard path in hydropower field

Recovery trends in marine mammal populations.

Directory of Open Access Journals (Sweden)

Anna M Magera

Full Text Available Marine mammals have greatly benefitted from a shift from resource exploitation towards conservation. Often lauded as symbols of conservation success, some marine mammal populations have shown remarkable recoveries after severe depletions. Others have remained at low abundance levels, continued to decline, or become extinct or extirpated. Here we provide a quantitative assessment of (1 publicly available population-level abundance data for marine mammals worldwide, (2 abundance trends and recovery status, and (3 historic population decline and recent recovery. We compiled 182 population abundance time series for 47 species and identified major data gaps. In order to compare across the largest possible set of time series with varying data quality, quantity and frequency, we considered an increase in population abundance as evidence of recovery. Using robust log-linear regression over three generations, we were able to classify abundance trends for 92 spatially non-overlapping populations as Significantly Increasing (42%, Significantly Decreasing (10%, Non-Significant Change (28% and Unknown (20%. Our results were comparable to IUCN classifications for equivalent species. Among different groupings, pinnipeds and other marine mammals (sirenians, polar bears and otters showed the highest proportion of recovering populations, likely benefiting from relatively fast life histories and nearshore habitats that provided visibility and protective management measures. Recovery was less frequent among cetaceans, but more common in coastal than offshore populations. For marine mammals with available historical abundance estimates (n = 47, larger historical population declines were associated with low or variable recent recoveries so far. Overall, our results show that many formerly depleted marine mammal populations are recovering. However, data-deficient populations and those with decreasing and non-significant trends require attention. In particular

Trends in air concentration and deposition at background monitoring sites in Sweden - major inorganic compounds, heavy metals and ozone

Energy Technology Data Exchange (ETDEWEB)

Kindbom, K.; Svensson, Annika; Sjoeberg, K.; Pihl Karlsson, G.

2001-09-01

This report describes concentrations in air of sulphur compounds, soot, nitrogen compounds and ozone in Sweden between 1985-1998. Time trends of concentration in precipitation and deposition of sulphate, nitrate, ammonium, acidity, base cations and chloride in six different regions covering Sweden are evaluated during the period 1983-1998. Trends of heavy metals in precipitation have been analysed for the period 1983-1998 and the change in heavy metal concentration, 1975-1995, in mosses is described. Data used in the trend analyses originates from measurements performed at six Swedish EMEP stations and from approximately 25 stations within the national Precipitation Chemistry Network. Two different statistical methods, linear regression and the non-parametric Mann Kendall test, have been used to evaluate changes in annual mean values. Time trends of concentration of sulphur dioxide, particulate sulphate, soot, nitrogen dioxide, total nitrate and total ammonium in air show highly significant decreasing trends, except for soot at one station in northern Sweden. Concentrations of ozone have a strong seasonal variation with a peak occurring in spring every year. However, annual ozone concentrations show no obvious trends in spite of decreasing emissions of the precursors NOx and VOC. A slight indication of a decreasing trend in the number of ozone episodes might be seen from 1990 to 1998. Sulphate concentrations in precipitation and deposition show strongly significant decreasing trends in the whole country. Concentrations and deposition of nitrate and ammonium have been decreasing in all areas except for nitrate at stations in south-west and north-west Sweden and ammonium in south-west Sweden. Acidity has decreased in all areas since 1989, resulting in increasing pH values in Sweden. The interannual variations of concentration and deposition of base cations and chloride are large and few general trends can be seen during 1983-1997. Time trends of four heavy metals in

Development trends for diagnostic systems in nuclear power plants

International Nuclear Information System (INIS)

Kunze, U.; Pohl, U.

1998-01-01

Monitoring systems used in nuclear power plants have made remarkable progress over the past four or five years. Development has followed the trends and changes in philosophy for the purpose of monitoring systems in nuclear power plants: They are no longer expected to fulfill only safety tasks, the plant personnel require information on which to base condition-oriented maintenance. A new generation of monitoring and diagnostic systems has been developed by Siemens recently. This new generation, called Series '95, is PC-based. An overview is given for the KUeS '95 loose parts diagnostic system, the SUeS '95 vibration monitoring system, the FLUeS leak detection system and the SIPLUG valve diagnostics system. The objectives behind the development of these new systems are both safety-related and economic. The new systems improve the reliability and quality of monitoring techniques and incorporate better detection and diagnostic capabilities. Progress has also been made in automation of the systems so as to reduce routine work, give higher sensitivity for the monitoring task and reduce the scope of maintenance. (author)

Urban partnerships in low-carbon development: Opportunities and challenges of an emerging trend in global climate politics

Directory of Open Access Journals (Sweden)

Jan Beermann

2014-05-01

Full Text Available This study explores the linkages between two recent trends in global climate governance. The first trend is the growing focus on cities in the multi-level governance of climate change. Whereas international climate change negotiations often end in deadlock, many urban centers across the world are taking the lead. Industrialized cities from the Global North and increasingly cities from the emerging Southern economies are experimenting with innovative and ambitious programs to reduce their local carbon footprints. A second trend is the expan¬ding urban North-South cooperation in the area of low-carbon development. This cooperation takes various forms, such as city twinning, transnational municipal networks and trans-local development cooperation. A key target of these initiatives is to develop joint projects and exchange knowledge to foster low-carbon development pathways. This study analyzes the conditions of success and failure in selected Indo-German urban low-carbon partnerships with a particular focus on institutional arrangements. The paper presents evidence from three initiatives and argues that successful trans-local cooperation depends largely on the interplay between institutional forms and the development of social capital. Building on these findings, the paper discusses what lessons may be drawn from the emergence of urban North-South cooperation for the future development of global climate governance.

Some trends and perspectives on globalization, economic growth, equality, and development

Directory of Open Access Journals (Sweden)

Giuseppe Ammendola

2011-01-01

Full Text Available The world economy is more complex than it has ever been. This paper looks at some frameworks used for description, analysis, and prediction in the three areas of economic growth, equality, and development, while also highlighting some important past and current trends. The selection of frameworks and trends represents clearly a necessarily brief and subjective choice of the author on the basis of his perception of their “usefulness” for purposes of public and private decision-making.The paper starts by discussing how economic growth is impacting the classification of the economies of the world. It then looks at how countries’ economies can be viewed in terms of ease of doing business, of adaptability to openness and change, and of types of capitalism adopted. In the second section, issues of economic inequality within and between the countries of the world and their citizens are examined. In the third section, the paper looks at development. It starts by briefly discussing the merits of going beyond GDP and of looking at the Human Development Index (HDI in order to try to measure other forms of progress, such as in health and education. The paper then traces the evolution of development economics and the advice given to policy makers in developing countries, and also examines the role of institutions in development and the controversies surrounding foreign aid. It concludes by looking briefly at additional dimensions of human development such as empowerment and sustainability.The picture that emerges is one of a world in which decision-makers have to make use in a combined way of a plurality of disciplines to understand the realities confronting them and to design and implement good policies. In so doing, they have to confront the challenges of appropriate sequencing, must very often choose second-best options, and have to make clever use of the lessons learned from countries with very different geographical, political, economic, social

Wittekind, Anna; Walton, Janette

2014-12-01

Estimating trends in dietary intake data is integral to informing national nutrition policy and monitoring progress towards dietary guidelines. Dietary intake of sugars is a controversial public health issue and guidance in relation to recommended intakes is particularly inconsistent. Published data relating to trends in sugars intake are relatively sparse. The purpose of the present review was to collate and review data from national nutrition surveys to examine changes and trends in dietary sugars intake. Only thirteen countries (all in the developed world) appear to report estimates of sugars intake from national nutrition surveys at more than one point in time. Definitions of dietary sugars that were used include 'total sugars', 'non-milk extrinsic sugars', 'added sugars', sucrose' and 'mono- and disaccharides'. This variability in terminology across countries meant that comparisons were limited to within countries. Hence trends in dietary sugars intake were examined by country for the whole population (where data permitted), and for specific or combined age and sex subpopulations. Findings indicate that in the majority of population comparisons, estimated dietary sugars intake is either stable or decreasing in both absolute (g/d) and relative (% energy) terms. An increase in sugars intake was observed in few countries and only in specific subpopulations. In conclusion, the findings from the present review suggest that, in the main, dietary sugars intake are decreasing or stable. A consistent approach to estimation of dietary sugars intake from national nutrition surveys is required if more valid estimates of changes in dietary sugars intakes are required in the future.

Trends in passenger transport energy use in South Korea

International Nuclear Information System (INIS)

Eom, Jiyong; Schipper, Lee

2010-01-01

Having a clear understanding of transport energy use trends is crucial to identifying opportunities and challenges for efficient energy use for the transport sector. To this date, however, no detailed analysis has been conducted with regard to rapidly growing passenger transport energy use in South Korea. Using bottom-up data developed from a variety of recent sources, we described the trends of transport activity, energy use, and CO 2 emissions from South Korea's transport sector since 1986 with a particular focus on its passenger transport. By decomposing the trends in passenger transport energy use into activity, modal structure, and energy intensity, we showed that while travel activity has been the major driver of the increase in passenger transport energy use in South Korea, the increase was to some extent offset by the recent favorable structural shift toward bus travel and away from car travel. We also demonstrated that while bus travel has become less energy intensive since the Asian Financial Crisis, car travel has become increasingly energy intensive.

2015-01-01

The objective was to develop a case-pattern model for Lassa fever (LF) among humans and derive predictors of time-trend point distribution of LF cases in Liberia in view of the prevailing under-reporting and public health challenge posed by the disease in the country. A retrospective 5 years data of LF distribution countrywide among humans were used to train a time-trend model of the disease in Liberia. A time-trend quadratic model was selected due to its goodness-of-fit (R2 = 0.89, and P Liberia, on which a predictive model was developed. We proposed a computationally feasible two-stage space-time permutation approach to estimate the time-trend parameters and conduct predictive inference on LF in Liberia.

Undergraduate Neuroscience Majors: A Missed Opportunity for Psychiatry Workforce Development.

Science.gov (United States)

Goldenberg, Matthew N; Krystal, John H

2017-04-01

This study sought to determine whether and to what extent medical students with an undergraduate college major in neuroscience, relative to other college majors, pursue psychiatry relative to other brain-based specialties (neurology and neurosurgery) and internal medicine. The authors analyzed data from AAMC matriculation and graduation surveys for all students who graduated from US medical schools in 2013 and 2014 (n = 29,714). Students who majored in neuroscience, psychology, and biology were compared to all other students in terms of their specialty choice at both time points. For each major, the authors determined rates of specialty choice of psychiatry, neurology, neurosurgery, and, for comparison, internal medicine. This study employed Chi-square statistic to compare odds of various specialty choices among different majors. Among medical students with an undergraduate neuroscience major (3.5% of all medical students), only 2.3% preferred psychiatry at matriculation, compared to 21.5% who chose neurology, 13.1% neurosurgery, and 11% internal medicine. By graduation, psychiatry specialty choice increased to 5.1% among neuroscience majors while choice of neurology and neurosurgery declined. Psychology majors (OR = 3.16, 95% CI 2.60-4.47) but not neuroscience majors (OR 1.28, 0.92-1.77) were more likely than their peers to choose psychiatry. Psychiatry struggles to attract neuroscience majors to the specialty. This missed opportunity is an obstacle to developing the neuroscience literacy of the workforce and jeopardizes the neuroscientific future of our field. Several potential strategies to address the recruitment challenges exist.

Oil majors under states pressure: two examples in the Caspian basin

International Nuclear Information System (INIS)

Lussac, Samuel; Raballand, Gael

2011-01-01

All over the world, and especially in developing countries, governments strive to strengthen national oil companies over oil and gas majors. The Caspian, and notably Azerbaijan and Kazakhstan, is not an exception to this current trend. This article sheds light on the leverages both Azerbaijani and Kazakhstani governments have used to increase pressure over oil and gas multinationals. In a first step, they both established a publicly-owned integrated company managed by the presidential entourage. Then, Azerbaijan and Kazakhstan have applied various instruments. Baku has sought to increase its own oil production to decrease the role of majors while Astana has preferred to use ecological, fiscal, legal and logistical leverages. However, in both cases, the outcome has been rather similar since the increasing pressure over majors has not necessarily led to benefit local populations

Sikora, W

1983-01-01

Research programs on underground black coal mining in Poland are discussed. It is assumed that no major technology changes will take place by the year 2000. Second generation of mining technologies will be used after the year 2000. The following technologies of the second generation are discussed: in-situ gasification, chemical coal disintegration, manless hydraulic mining with hydraulic transport. Research programs on technologies of the second generation should guarantee their commercial and economic use by the year 2000. The following targets for research programs aimed at increasing productivity, reducing mining cost, reducing labor and increasing safety in mining, covering the next 2 decades are comparatively evaluated: increasing advance rate of longwall faces, increasing machine time of integrated face systems by at least 20%, improving design of powered supports for eliminating rock falls, development of heavy-duty face systems for longwall mining with hydraulic stowing, development of face systems for mining thick coal seams on their whole thickness, slice mining thick coal seams with artificial roofs, bidirectional longwall mining by shearer loaders, use of more elastic and reliable mining systems.

by a distinct spatial pattern and strongly dominated by negative trends in Normalized Difference Vegetation Index (NDVI). The aim of the paper is to explain this distinct pattern. When studied over the period 2000–2012, using NDVI data from the MODIS sensor the spatial pattern of NDVI trends indicates that non......-climatic factors are involved. By relating NDVI trends to landscape elements and land use change we demonstrate that NDVI trends in the north-western parts of the study area are mostly related to landscape elements, while this is not the case in the south-eastern parts, where rapidly changing land use, including....... expansion of irrigation, plays a major role. It is inferred that a process of increased redistribution of fine soil material, water and vegetation from plateaus and slopes to valleys, possibly related to higher grazing pressure, may provide an explanation of the observed pattern of NDVI trends.

In this article we analyse the current authorised treatments and trends in early drug development for cystic fibrosis (CF) in the European Union for the time period 2000-2016. The analysis indicates a significant improvement in the innovation and development of new potential medicines for CF, shifting from products that act on the symptoms of the disease towards new therapies targeting the cause of CF. However, within these new innovative medicines, results for CF transmembrane conductance regulator (CFTR) modulators indicate that one major challenge for turning a CF concept product into an actual medicine for the benefit of patients resides in the fact that, although pre-clinical models have shown good predictability for certain mutations, a good correlation to clinical end-points or biomarkers ( e.g. forced expiratory volume in 1 s and sweat chloride) for all mutations has not yet been achieved. In this respect, the use of alternative end-points and innovative nonclinical models could be helpful for the understanding of those translational discrepancies. Collaborative endeavours to promote further research and development in these areas as well as early dialogue with the regulatory bodies available at the European competent authorities are recommended.

The primary purpose of this report is to present information relating to flow-adjusted temporal trends in major-ion constituents and properties for 16 sampling sites in the Tongue and Powder River watersheds based on data collected during 1980–2010. In association with this primary purpose, the report presents background information on major-ion characteristics (including specific conductance, calcium, magnesium, potassium, sodium adsorption ratio, sodium, alkalinity, chloride, fluoride, dissolved sulfate, and dissolved solids) of the sampling sites and coal-bed methane (CBM) produced water (groundwater pumped from coal seams) in the site watersheds, trend analysis methods, streamflow conditions, and factors that affect trend results. The Tongue and Powder River watersheds overlie the Powder River structural basin (PRB) in northeastern Wyoming and southeastern Montana. Limited extraction of coal-bed methane (CBM) from the PRB began in the early 1990’s, and increased dramatically during the late 1990’s and early 2000’s. CBM-extraction activities produce discharges of water with high concentrations of dissolved solids (particularly sodium and bicarbonate ions) relative to most stream water in the Tongue and Powder River watersheds. Water-quality of CBM produced water is of concern because of potential effects of sodium on agricultural soils and potential effects of bicarbonate on aquatic biota. Two parametric trend-analysis methods were used in this study: the time-series model (TSM) and ordinary least squares regression (OLS) on time, streamflow, and season. The TSM was used to analyze trends for 11 of the 16 study sites. For five sites, data requirements of the TSM were not met and OLS was used to analyze trends. Two primary 10-year trend-analysis periods were selected. Trend-analysis period 1 (water years 1986–95; hereinafter referred to as period 1) was selected to represent variability in major-ion concentrations in the Tongue and Powder River

Googling trends in conservation biology.

Proulx, Raphaël; Massicotte, Philippe; Pépino, Marc

2014-02-01

Web-crawling approaches, that is, automated programs data mining the internet to obtain information about a particular process, have recently been proposed for monitoring early signs of ecosystem degradation or for establishing crop calendars. However, lack of a clear conceptual and methodological framework has prevented the development of such approaches within the field of conservation biology. Our objective was to illustrate how Google Trends, a freely accessible web-crawling engine, can be used to track changes in timing of biological processes, spatial distribution of invasive species, and level of public awareness about key conservation issues. Google Trends returns the number of internet searches that were made for a keyword in a given region of the world over a defined period. Using data retrieved online for 13 countries, we exemplify how Google Trends can be used to study the timing of biological processes, such as the seasonal recurrence of pollen release or mosquito outbreaks across a latitudinal gradient. We mapped the spatial extent of results from Google Trends for 5 invasive species in the United States and found geographic patterns in invasions that are consistent with their coarse-grained distribution at state levels. From 2004 through 2012, Google Trends showed that the level of public interest and awareness about conservation issues related to ecosystem services, biodiversity, and climate change increased, decreased, and followed both trends, respectively. Finally, to further the development of research approaches at the interface of conservation biology, collective knowledge, and environmental management, we developed an algorithm that allows the rapid retrieval of Google Trends data. © 2013 Society for Conservation Biology.

Three-dimensional trend mapping using gamma-ray well logs: Simpson Group, south-central Kansas

International Nuclear Information System (INIS)

Doveton, J.H.; Davis, J.C.; Zhu Ke-an

1984-01-01

Gamma-ray logs are useful indicators of shale content as a function of depth. When several gamma-ray logs are drawn from an area, they may be interpreted in terms of shale variation in the 3 dimensions of geographic space and depth. (For several years, statistical moments of logs have been mapped as an expression of major trends of depth variation in lithologic development across an area. Moments have the additional valuable property that they also define unique polynomial trends as a function of depth. This property allows the interpolation of moments between well control to generate a 3-dimensional grid of shale referenced to any location and depth. The method was applied to the Simpson Group (Ordovician) of southcentral Kansas. Graphic results of the study outline the shapes of major sandstone and shale bodies in a series of cross sections.) The areal disposition of the initial transgressive sandstone is revealed on a basal slice map. The method is general and can be used in conjunction with other logs. As an example, use of either a neutron, density, or sonic log could be applied to 3-dimensional trend representations of porosity variation in reservoir units

The development of scenarios for quantitative or qualitative analysis is a key element of the assessment of the safety of geological disposal systems. As an outcome of an international workshop attended by European and the Japanese implementers, a number of features common to current methodologies could be identified, as well as trends in their evolution over time. In the late nineties, scenario development was often described as a bottom-up process, whereby scenarios were said to be developed in essence from FEP databases. Nowadays, it is recognised that, in practice, the approaches actually adopted are better described as top-down or 'hybrid', taking as their starting point an integrated (top-down) understanding of the system under consideration including uncertainties in initial state, sometimes assisted by the development of 'storyboards'. A bottom-up element remains (hence the term 'hybrid') to the extent that FEP databases or FEP catalogues (including interactions) are still used, but the focus is generally on completeness checking, which occurs parallel to the main assessment process. Recent advances focus on the consistent treatment of uncertainties throughout the safety assessment and on the integration of operational safety and long term safety. (author)

Microporous polyethylene separators — today and tomorrow. Separator development trends for modern automotive batteries

Science.gov (United States)

Böhnstedt, Werner

During the past decade, the design of modern automotive batteries has undergone a fundamental change. The introduction of microporous polyethylene pocket separators has resulted in an approximately 8% better volume utilization. Besides increasing the energy density, the polyethylene envelope has enalbed an improvement in cold-cranking performance and has raised the production efficiency. A first failure-mode analysis of pocket-separated automotive batteries in Europe with respect to leaf separation is presented. For comparable service life, a shift in failure mode has been found. Although corrosion of the positive electrode still dominates, a significant increase in positive active-material shedding is noted. This is certainly a consequence of the general trend towards lower antimony contents. Shorting through the separator is only found in cases of severe battery mistreatment. This positive, intermediary result is supplemented by an outlook on emerging development trends. Future automotive batteries will experience elevated operating temperatures, higher cycling loads, and maintenance freedom. Battery tests at temperatures up to 75 °C with various alloy combinations show that the hybrid design is best suited to meet the expected requirements. Microporous polyethylene pocket separation is not expected to be a limiting factor; the trend to lower antimony alloy content and increased cycling load will demonstrate the advantage of this separation even more clearly than in the past. Optimization of the already achieved, balanced separator characteristics profile with the reference parameters of electrical performance, water loss, durability and machinability will stimulate further development work.

DISC1 pathway in brain development: exploring therapeutic targets for major psychiatric disorders

Atsushi eKamiya

2012-03-01

Full Text Available Genetic risk factors for major psychiatric disorders play key roles in neurodevelopment. Thus, exploring the molecular pathways of risk genes is important not only for understanding the molecular mechanisms underlying brain development, but also to decipher how genetic disturbances affect brain maturation and functioning relevant to major mental illnesses. During the last decade, there has been significant progress in determining the mechanisms whereby risk genes impact brain development. Nonetheless, given that the majority of psychiatric disorders have etiological complexities encompassing multiple risk genes and environmental factors, the biological mechanisms of these diseases remain poorly understood. How can we move forward in our research for discovery of the biological markers and novel therapeutic targets for major mental disorders? Here we review recent progress in the neurobiology of Disrupted in schizophrenia 1 (DISC1, a major risk gene for major mental disorders, with a particular focus on its roles in cerebral cortex development. Convergent findings implicate DISC1 as part of a large, multi-step pathway implicated in various cellular processes and signal transduction. We discuss links between the DISC1 pathway and environmental factors, such as immune/inflammatory responses, which may suggest novel therapeutic targets. Existing treatments for major mental disorders are hampered by a limited number of pharmacological targets. Consequently, elucidation of the DISC1 pathway, and its association with neuropsychiatric disorders, may offer hope for novel treatment interventions.

1993-04-01

Previously identified and current trends in the development of computer systems and in the use of computers for health care applications are reviewed. Trends identified in a 1982 article were increasing miniaturization and archival ability, increasing software costs, increasing software independence, user empowerment through new software technologies, shorter computer-system life cycles, and more rapid development and support of pharmaceutical services. Most of these trends continue today. Current trends in hardware and software include the increasing use of reduced instruction-set computing, migration to the UNIX operating system, the development of large software libraries, microprocessor-based smart terminals that allow remote validation of data, speech synthesis and recognition, application generators, fourth-generation languages, computer-aided software engineering, object-oriented technologies, and artificial intelligence. Current trends specific to pharmacy and hospitals are the withdrawal of vendors of hospital information systems from the pharmacy market, improved linkage of information systems within hospitals, and increased regulation by government. The computer industry and its products continue to undergo dynamic change. Software development continues to lag behind hardware, and its high cost is offsetting the savings provided by hardware.

1995-01-01

According to the usual meaning, technological trends are determined by main companies and leading countries with capacity for the development and marketing of technology. Presently, those trends are addressed to: the development of cleaner and more efficient process for fossil fuels utilization (atmospheric and pressurized fluidized beds, integrated gasification in combined cycle, advanced combined cycles, etc), the development of safer and more economic nuclear reactors; the efficiency increase in both generation and utilisation of energy, including demand side management and distribution automation; and the reduction of cost of renewable energies. Singular points of these trends are: the progress in communication technologies (optical fibre, trucking systems, etc.); the fuel cells; the supercritical boilers; the passive reactors; the nuclear fusion; the superconductivity; etc. Spain belongs to the developed countries but suffer of certain technology shortages that places it in a special situation.

Nowadays, there is quite high demand for electromagnetic transient (EMT) analysis programs and real-time simulators for power systems. In addition to the conventional demand such as overvoltage, over-current and oscillation simulations, the new demand that includes simulations of power-electronics circuits and power quality is increasing. With this background, development groups of EMT programs and real-time simulators have made progress in terms of computational performance and user experience. In Japan, Central Research Institute of Electric Power Industry has newly developed an EMT analysis program called XTAP (eXpandable Transient Analysis Program). This article overviews these international and domestic development trends of EMT analysis programs and real-time simulators.

2015-12-01

Full Text Available he specifically multidisciplinary approach employed in the present paper is motivated by the validity of Engel’s sociological laws, the usefulness of the elasticity of the population’s food products demand according to income, the statistical association between the contraction of the share of expenditures for these goods and the expansion of economy development, and the consistent assessment of the trends in population well-being, in keeping with the research of family budgets, focusing on the case of Romania in the last century. The introduction is devoted to the statistical, economic and sociological tools for assessing economic development and the trends in well-being. The first section describes the weighting coefficients in the universe of interpret indexes, and the second presents the methodology relating to a secular instrument of assessing the degree of economic development and the synthetic evaluation of the trends of well-being in Romania, in parallel to a number of maximum and minimum (European and international trends. The results presented, and the discussion caused by the statistical confrontation of that statistical, economic and sociological information, embrace, with the conclusions, the attempt made by the whole of the paper, to round up, by means of this tool, a necessary set of secular or Schumpeterian indicators, harmonized and comparable, of the GDP/capita type, or such as cost of life index, consumer price index, public and external debt, etc.; such already constructed indicators contribute to delineating the historical and macro-behavioural specificity of such an economy in Eastern Europe as that of Romania.

Emerging trends in informal sector recycling in developing and transition countries

Ezeah, Chukwunonye; Fazakerley, Jak A.; Roberts, Clive L.

2013-01-01

Highlights: • Reviewed emerging trends in Informal Sector Recycling (ISR) in developing countries. • In some countries we found that ISR is the key factor in the recycling of waste materials. • Overall impact of ISR upon the urban economy and environment is positive. • In some instances ISR subsidises large areas of the formal sector. • Ignoring the informal sector could result in unsustainable interventions. - Abstract: Optimistic estimates suggest that only 30–70% of waste generated in cities of developing countries is collected for disposal. As a result, uncollected waste is often disposed of into open dumps, along the streets or into water bodies. Quite often, this practice induces environmental degradation and public health risks.

Highlights: • Reviewed emerging trends in Informal Sector Recycling (ISR) in developing countries. • In some countries we found that ISR is the key factor in the recycling of waste materials. • Overall impact of ISR upon the urban economy and environment is positive. • In some instances ISR subsidises large areas of the formal sector. • Ignoring the informal sector could result in unsustainable interventions. - Abstract: Optimistic estimates suggest that only 30–70% of waste generated in cities of developing countries is collected for disposal. As a result, uncollected waste is often disposed of into open dumps, along the streets or into water bodies. Quite often, this practice induces environmental degradation and public health risks. Notwithstanding, such practices also make waste materials readily available for itinerant waste pickers. These ‘scavengers’ as they are called, therefore perceive waste as a resource, for income generation. Literature suggests that Informal Sector Recycling (ISR) activity can bring other benefits such as, economic growth, litter control and resources conservation.

Congenital heart disease (CHD) is a common condition in children in Sub-Saharan Africa (SSA), where it is associated with poor outcomes. Diagnosis of CHD in SSA depends essentially on echocardiography, which is available only in few urban referral centers. Our aim was to assess time changes in the pattern of referral for pediatric echocardiography and the subsequent diagnosis of structural CHD in a major SSA city. All pediatric echocardiography performed between 2004 and 2013 at the echocardiography laboratory of the Yaounde General Hospital were reviewed. The primary indication of the study and the presence of structural CHD were recorded. Between 2004 and 2013, 9,390 echocardiograms were performed and 834 (8.9%) children aged 1 day to 15 years underwent echocardiography at the center, and 227 (27.2%) cases of definite structural CHD were diagnosed, with 123 (54.2%) in boys. The most frequent indications for echocardiography were heart murmurs (40%) and the suspicion of CHD (37.4%). The commonest CHD was ventricular septal defect (VSD) (30%) with tetralogy of Fallot being the most frequent cyanotic heart lesion (5.3%). The proportion of pediatric echocardiography decreased from 13.3% in 2004-2005 to 6.1% in 2012-2013 (P=0.001) but not in a linear fashion (P=0.072 for linear trend).The diagnosis of structural CHD increased from 25.1% in 2004-2005 to 27.1% in 2012-2013. This increase however was non-significant (P=0.523) and did not follow a linear trend (P=0.230). The pattern of referral for pediatric echocardiography at this center has changed over time, but diagnosis of structural CHD has remained the same. Improving access to this diagnostic procedure and subsequent treatment of diagnosed CHD will help improving the outcome of the disease in this setting.

Based on the cyclone detection and tracking algorithm previously developed (Trigo, 2006) we have assessed the inter-annual variability and cyclone frequency trends between 1960 and 2000 for the Euro-Atlantic sector using the highest spatial resolution available (1.125° x 1.125°) from the ERA-40 Surface Level Pressure. Additionally, trends for the u and v wind speed components are also computed at the monthly and seasonal scales, using the same dataset. All cyclone and wind speed trend maps were computed with the corresponding statistical significance field. Results reveal a significant frequency decrease (increase) in the western Mediterranean (Greenland and Scandinavia), particularly in December, February and March. Seasonal and monthly analysis of wind speed trends shows similar spatial patterns. We show that these changes in the frequency of low pressure centers and the associated wind patterns are partially responsible for trends of the significant height of waves. Throughout the extended winter months (ONDJFM), regions with positive (negative) wind magnitude trends, of up to 5 cm/s per year, often correspond to regions of positive (negative) significant wave height trends. The cyclone and wind speed trends computed for the JFM months are well matched by the corresponding trends in significant wave height, with February being the month with the highest trends (negative south of 50°N up to -3 cm/year, and positive up to 5cm/year just north of Scotland). Using precipitation data from ECMWF reanalyses and a CRU high resolution dataset we show the impact of these trends in cyclone frequencies upon the corresponding precipitation trends in the influenced areas. It is also shown that these changes are partially linked to major shifts on the indices of large-scale patterns modes, namely the North Atlantic Oscillation (NAO), the Eastern Atlantic (EA) and the Scandinavian Patterns (SCAN).

Usher, Wayne T

2011-08-01

This study was concerned with indentifying motivations and trends associated with a health website recommendation from eight of Australia's major health professions to the health consumer. Health professions included in this study are: psychiatrists, general practitioners, social workers, dietitians, chiropractors, physiotherapists, optometrists and pharmacists. An online survey (www.limesurvey.org) was developed from a common set of questions negotiated between all eight health professions. Survey questions were constructed in an attempt to identify participants' reasons for or against recommending a health website to a patient. A 5-point scale (not, slightly, neutral, moderately, strongly) to measure influence was used throughout the question set. This study indicates that Australian general practitioners (GPs) were the highest Australian health professionals to undertake a health website recommendation (86%), followed by psychiatrists (80%), with the lowest being physiotherapists (42%) and optometrists (33%). A profile of the Australian health professional who recommends a health website is identified as male, aged above 50 years, has had more than 10 years experience, works in a major city, is in private practice and has patient numbers exceeding 500 in a 12-month period (2009). Recommendations from this study include the need to develop mechanisms that identify high-quality online medical information and the development and implementation of Continuing Professional Development (CPD) courses which up-skill health professionals concerning the recommendation of health websites for health care delivery.

Identifying hemodynamically unstable patients in a timely fashion in intensive care units (ICUs) is crucial because it can lead to earlier interventions and thus to potentially better patient outcomes. Current alert algorithms are typically limited to detecting dangerous conditions only after they have occurred and suffer from high false alert rates. Our objective was to predict hemodynamic instability at least two hours before a major clinical intervention (e.g., vasopressor administration), while maintaining a low false alert rate. From the MIMIC II database, containing ICU minute-by-minute heart rate (HR) and invasive arterial blood pressure (BP) monitoring trend data collected between 2001 and 2005, we identified 132 stable and 104 unstable patients that met our stability-instability criteria and had sufficient data points. We first derived additional physiological parameters of shock index, rate pressure product, heart rate variability, and two measures of trending based on HR and BP. Then we developed 220 statistical features and systematically selected a small set to use for classification. We applied multi-variable logistic regression modeling to do classification and implemented validation via bootstrapping. Area under receiver-operating curve (ROC) 0.83+/-0.03, sensitivity 0.75+/-0.06, and specificity 0.80+/-0.07; if the specificity is targeted at 0.90, then the sensitivity is 0.57+/-0.07. Based on our preliminary results, we conclude that the algorithms we developed using HR and BP trend data may provide a promising perspective toward reliable predictive alerts for hemodynamically unstable patients.

The Dietary Guidelines for Americans (DGA) is published every 5 y jointly by the Department of Health and Human Services (HHS) and the USDA and provides a framework for US-based food and nutrition programs, health promotion and disease prevention initiatives, and research priorities. Summarized in this report are the methods, major conclusions, and recommendations of the Scientific Report of the 2015 US Dietary Guidelines Advisory Committee (DGAC). Early in the process, the DGAC developed a conceptual model and formulated questions to examine nutritional risk and determinants and impact of dietary patterns in relation to numerous health outcomes among individuals aged ≥2 y. As detailed in the report, an expansive, transparent, and comprehensive process was used to address each question, with multiple opportunities for public input included. Consensus was reached on all DGAC's findings, including each conclusion and recommendation, and the entire report. When research questions were answered by original systematic literature reviews and/or with existing, high-quality expert reports, the quality and strength of the evidence was formally graded. The report was organized around the following 5 themes: 1) food and nutrient intakes and health: current status and trends; 2) dietary patterns, foods and nutrients, and health outcomes; 3) diet and physical activity behavior change; 4) food and physical activity environments; and 5) food sustainability and food safety. The following 3 cross-cutting topics were addressed: 1) sodium, 2) saturated fat, and 3) added sugars. Physical activity recommendations from recent expert reports were endorsed. The overall quality of the American diet was assessed to identify overconsumed and underconsumed nutrients of public health concern. Common food characteristics of healthy dietary patterns were determined. Features of effective interventions to change individual and population diet and physical activity behaviors in clinical, public

2013-12-01

To examine trends in infant mortality rate (IMR), adult mortality and life expectancy (LE) in the two major Fijian ethnic groups since 1975. Estimates of IMR, adult mortality (15-59 years) and LE by ethnicity are calculated from previously unreported Fiji Ministry of Health data and extracted from published sources. Over 1975-2008: IMR decreased from 33 to 20 deaths/1,000 live births in i-Taukei (Fiji Melanesians); and 38 to 18 in Fijians of Indian descent. Increased adult male mortality among i-Taukei and decline among Fijians of Indian descent led to an equal probability of dying in 2007 of 29%; while in female adults the probability trended upwards in i-Taukei to 25%, and declined in Fijians of Indian descent to 17%. Life expectancy in both ethnicities increased until 1985 (to 64 years for males; 68 for females) then forming a plateau in males of both ethnicities, and Fijian females of Indian descent, but declining in i-Taukei females to 66 years in 2007. Despite IMR declines over 1975-2008, LE for i-Taukei and Fijians of Indian descent has not increased since 1985, and has actually decreased in i-Taukei women, consistent with trends in adult mortality (15-59 years). Mortality analyses in Fiji that consider the entire population mask divergent trends in the major ethnic groups. This situation is most likely a consequence of non-communicable disease mortality, requiring further assessment and a strengthened response.

Kenya's major incidents profile is dominated by droughts, floods, fires, terrorism, poisoning, collapsed buildings, accidents in the transport sector and disease/epidemics. With no integrated emergency services and a lack of resources, many incidents in Kenya escalate to such an extent that they become major incidents. Lack of specific training of emergency services personnel to respond to major incidents, poor coordination of major incident management activities, and a lack of standard operational procedures and emergency operation plans have all been shown to expose victims to increased morbidity and mortality. This report provides a review of some of the major incidents in Kenya for the period 2000-2012, with the hope of highlighting the importance of developing an integrated and well-trained Ambulance and Fire and Rescue service appropriate for the local health care system.

Full Text Available Background: The results of foreign studies have shown that psychomotor development of adolescents from orphanages falls significantly behind common developmental norms. In the Czech Republic, there is a lack of evidence of this issue despite the fact that some experts emphasize the possible defects of institutional care in the Czech Republic.Objective: The purpose of the study was to compare the level of psychomotor development of 13 year old adolescents from orphanages located in Prague and their counterparts from majority society. Methods: Psychomotor development of adolescents was tested with the complete form of the Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2, which consists of 52 items, divided into 12 dimensions assessing the level of fine motor skills, gross motor skills, coordination and agility. The study sample consisting of 57 adolescents (age 13.47 ± 0.26 years included a sample of 21 adolescents from orphanages and 36 adolescents from majority society living in the Prague region. Results: Compared to their counterparts from majority society, adolescents from orphanages achieved significantly lower scores only in the fine motor precision dimension (η2 = .13; p = .032. The study showed significant difference between boys from orphanages and boys from majority society in the fine motor precision dimension (η2 = .13; p = .028, boys from majority society achieved significantly higher scores in this dimension. The results did not find significant difference in any BOT-2 dimensions between girls from majority society and girls from orphanages. Adolescents from orphanages achieved higher scores in the dimensions of strength and agility, running speed and agility and strength. Conclusion: Differences in psychomotor development were not confirmed in the observed dimensions of bilateral coordination and balance between the sample of adolescents from orphanages in Prague and their counterparts from

Current nondestructive evaluation research and development trends in the United States

Jackson, Jerry

1992-01-01

An underlying theme present in much of the nondestructive evaluation (NDE) research and development occurring in the United States as well as worldwide is the application of physics and engineering principles toward understanding and optimizing NDE processes. Expanding this trend of using mathematical models for NDE processes is critical to the entire spectrum of NDE technology. In NDE research, modeling anchors the investigation in scientific, proven principles and establishes a firm technical basis to guide the design and development of inspection equipment and approaches. It also provides for understanding the capabilities and the limitations of whatever designs are selected and ultimately applied in the field. This paper reviews the status of these efforts, presents several examples where mathematical modeling is being profitably used for practical inspection work, and shows the path being taken in ongoing research.

Global Trends of Tropospheric NO2 Observed From Space

Science.gov (United States)

Schneider, P.; van der A, R. J.

2012-04-01

Nitrogen Dioxide (NO2) is one of the major atmospheric pollutants and is primarily emitted by industrial activity and transport. While observations of NO2 are frequently being carried out at air quality stations, such measurements are not able to provide a global perspective of spatial patterns in NO2 concentrations and their associated trends due to the stations' limited spatial representativity and an extremely sparse and often completely non-existent station coverage in developing countries. Satellite observations of tropospheric NO2 are able to overcome this issue and provide an unprecedented global view of spatial patterns in NO2 levels and due to their homogeneity are well suited for studying trends. Here we present results of a global trend analysis from nearly a decade of NO2 observations made by the SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CartograpHY) instrument onboard the Envisat satellite platform. Using only SCIAMACHY data allows for mapping global and regional trends at an unprecedented spatial resolution since no aggregation to the coarser resolution of other sensors is necessary. Monthly average tropospheric NO2 column data was acquired for the period between August 2002 and August 2011. A trend analysis was subsequently performed by fitting a statistical model including a seasonal cycle and linear trend to the time series extracted at each grid cell. The linear trend component and the trend uncertainty were then mapped spatially at both regional and global scales. The results show that spatially contiguous areas of significantly increasing NO2 levels are found primarily in Eastern China, with absolute trends of up to 4.05 (± 0.41) - 1015 molecules cm-2 yr-1 at the gridcell level and large areas showing rapid relative increases of 10-20 percent per year. In addition, many urban agglomerations in Asia and the Middle East similarly exhibit significantly increasing trends, with Dhaka in Bangladesh being the megacity with

2014-12-01

The post-civil war records of dog bite injuries (DBI) and rabies-like-illness (RLI) among humans in Liberia is a vital epidemiological resource for developing a predictive model to guide the allocation of resources towards human rabies control. Whereas DBI and RLI are high, they are largely under-reported. The objective of this study was to develop a time model of the case-pattern and apply it to derive predictors of time-trend point distribution of DBI-RLI cases. A retrospective 6 years data of DBI distribution among humans countrywide were converted to quarterly series using a transformation technique of Minimizing Squared First Difference statistic. The generated dataset was used to train a time-trend model of the DBI-RLI syndrome in Liberia. An additive detenninistic time-trend model was selected due to its performance compared to multiplication model of trend and seasonal movement. Parameter predictors were run on least square method to predict DBI cases for a prospective 4 years period, covering 2014-2017. The two-stage predictive model of DBI case-pattern between 2014 and 2017 was characterised by a uniform upward trend within Liberia's coastal and hinterland Counties over the forecast period. This paper describes a translational application of the time-trend distribution pattern of DBI epidemics, 2008-2013 reported in Liberia, on which a predictive model was developed. A computationally feasible two-stage time-trend permutation approach is proposed to estimate the time-trend parameters and conduct predictive inference on DBI-RLI in Liberia.

ECN is not only active in technological research and development; it also plays a major role in policy research and development. Since national energy policy is increasingly influenced by developments at the European level and vice versa, ECN is shifting its attention from a national to a European focus. More and more, national energy and environmental policies are implemented within the framework of EU (European Union) directives, while reversibly the success of European policies is dependent on harmonised national actions in a liberalised European energy market. To demonstrate this shifting research orientation towards a European position ECN decided to highlight four major national topics that dominated policy discussions in the Netherlands during 2003 in this special publication. The first topic concerns changes in national renewable energy policy. Earlier policies had led to a dramatic increase in imports of renewable electricity with major fiscal consequences and it was decided to redress the balance towards stimulating domestic investment in renewable energy capacity. In the summer of 2003 extreme weather events led to an electricity supply crisis providing a short-term argument to look into the policy options for preventing shortages. The opportunities and limitations of demand side response to electricity supply shortages is the second topic addressed. Regarding climate change policies the most notable development undoubtedly concerns the impending implementation of a greenhouse gas emissions trading scheme. The focus in this chapter is on the interaction between the EU directive on emissions trading and the Dutch approach. As a relatively small country the Netherlands has always found it difficult to make appropriate energy research and development choices. During 2003 new directions in RD and D policies were determined. Apart from the optimal choice of nationally relevant research priorities, an additional vexing problem concerns the relative amounts of

Here, we present and analyze three powerful long-term historical trends in energy, particularly electrical energy, as well as the opportunities and challenges associated with these trends. The first trend is from a world containing a diversity of energy currencies to one whose predominant currency is electricity, driven by electricity’s transportability, exchangeability, and steadily decreasing cost. The second trend is from electricity generated from a diversity of sources to electricity generated predominantly by free-fuel sources, driven by their steadily decreasing cost and long-term abundance. These trends necessitate a just-emerging third trend: from a grid in which electricity is transported uni-directionally, traded at near-static prices, and consumed under direct human control; to a grid in which electricity is transported bi-directionally, traded at dynamic prices, and consumed under human-tailored agential control. Early acceptance and appreciation of these trends will accelerate their remaking of humanity’s energy landscape into one in which energy is much more affordable, abundant and efficiently deployed than it is today; with major economic, geo-political, and environmental benefits to human society.

TRENDS REGARDING THE ROLE OF STATE ENTITIES IN SUPPORTING GROWTH AND ECONOMIC DEVELOPMENT

Florin Bonciu

2018-04-01

Full Text Available The paper focuses on the analysis of the consequences of several phenomena that have occurred in the past two decades in respect of the role played by state entities in supporting growth and economic development. Demographic and technical-scientific developments related to the Fourth Industrial Revolution were among the phenomena leading to an increasing trend in the role of state entities in supporting economic growth and development. In the meantime, other phenomena, including new technologies, economic integration and socio-cultural and historical processes, had a diminishing effect on the role played by state entities in supporting growth and economic development. By comparing the two categories of phenomena, the paper concludes that the phenomena supporting an increase in the role of state entities are more numerous and substantial, a fact that may assist decision-makers in developing appropriate approaches and strategies.

Full Text Available This empirical paper explores trends in innovation activities measured by a countries’ total patent application submission intensity relative to its population, and by analyzing U.S. granted patents data for cohorts of developed countries and developing countries. In addition to tabular and graphical analyses, I use a baseline regression model and a variant model thereof to assess the relative influence of a set of aggregate variables on innovation activities in eight manufacturing industries across two cohorts of countries (developed and developing where each cohort contains eight individual countries. Eight industries included in this study are: Chemical, Petroleum, electrical and electronics equipment, machinery, pharmaceutical, plastic, computer, and textile. The cohort of developed countries includes Australia, Canada, Czech Republic, France, Italy, Poland, Switzerland, and the United States. The cohort of developing countries includes Brazil, China, India, Malaysia, Mexico, Russia, South Africa, and Turkey. Per regression results, ethnic diversity is a statistically significant positive determinant of innovation for all industry aggregate patent count for both high income and developing countries. Also, per capita electricity usage, R&D expenditure as percent of GDP, and percent of population with internet access are three positive factors of innovation irrespective of industrial subsectors and position of a country in the development echelon. Interestingly, impact of ICT-services export is statistically significant and innovation boosting in developing countries in the cohort relative to countries in the cohort of developed countries. It also appears that trade openness served as a stronger stimulant of innovation activities for developing countries’ but not as much for the cohort of developed or high-income countries. This paper attempts to extend the literature on cross-country comparison of innovation activities by using two

Quantitative assessment of urban thermal environment has become a focus for urban climate and environmental science since the concept of urban heat island has been proposed. With the continual development of space information and computer simulation technology, substantial progresses have been made on quantitative assessment techniques and methods of urban thermal environment. The quantitative assessment techniques have been developed to dynamics simulation and forecast of thermal environment at various scales based on statistical analysis of thermal environment on urban-scale using the historical data of weather stations. This study reviewed the development progress of ground meteorological observation, thermal infrared remote sensing and numerical simulation. Moreover, the potential advantages and disadvantages, applicability and the development trends of these techniques were also summarized, aiming to add fundamental knowledge of understanding the urban thermal environment assessment and optimization.

On the basis of the illuminated materials were obtained the following conclusions: Signifi cant interest in the Arctic show today, not only the fi ve countries (Russia, USA, Canada, Norway, Denmark, who own Arctic territories, but also polar state (Iceland, Sweden, Finland, the European Union and Asia. As a consequence of that, it is expected that in the XXI century the Arctic region will be the focus of attention as an official Arctic 45, and a number of states whose territory is quite removed from it; For Russia, given the current, acute political conditions (sanctions, confrontation with the West, Ukrainian crisis and war in the Middle East development of Arctic territories, some moved away, moved on tomorrow and the day after tomorrow on the agenda. This approach is fundamentally fl awed and fraught with a number of threats, because other countries do not decrease, but only increase their interest in this issue; Territorial opposition to all those involved in the topic of causing instability in the Arctic region, but does not represent a real threat for the emergence of large-scale conflict. Therefore, making the choice between the hard pressure of national interests and the interests of harmonization of the Arctic states, Russia must be based on international cooperationand mutual consideration of interests in the development of its Arctic strategy; Considering the cooperation of the countries of the Arctic Council and their cooperation in the framework of a global economic forum G8, there are prerequisites for the decision of the Arctic confl ict through negotiation and compromise.

This study aims at interpreting the 2001-2012 trends of major air pollutants in Spain, with a major focus on evaluating their relationship with those of the national emission inventories (NEI) and policy actions. Marked downward concentration trends were evidenced for PM10, PM2.5 and CO. Concentrations of NO2 and NOx also declined but in a lesser proportion at rural and traffic sites. At rural sites O3 has been kept constant, whereas it clearly increased at urban and industrial sites. Comparison of the air quality trends and major inflection points with those from NEIs, the National Energy Consumption and the calendar of the implementation of major policy actions allowed us to clearly identify major benefits of European directives on power generation and industrial sources (such as the Large Combustion Plants and the Integrated Pollution Prevention and Control Directives). This, together with a sharp 2007-2008 decrease of coal consumption has probably caused the marked parallel decline of SO2, NOx and for PM2.5 concentrations. Also the effect of the EURO 4 and 5 vehicle emission standards on decreasing emissions of PM and CO from vehicles is noticeable. The smooth decline in NO2-NOx levels is mostly attributed to the low efficiency of EURO 4 and 5 standards in reducing real life urban driving NO2 emissions. The low NOx decrease together with the complexity of the reactions of O3 formation is responsible for the constant O3 concentrations, or even the urban increase. The financial crisis has also contributed to the decrease of the ambient concentration of pollutants; however this caused a major reduction of the primary energy consumption from 2008 to 2009, and not from 2007 to 2008 when ambient air PM and SO2 sharply decreased. The meteorological influence was characterized by a 2008-2012 period favorable to the dispersion of pollutants when compared to the 2001-2007. Copyright © 2014. Published by Elsevier B.V.

Controversies, development and trends of biofuel industry in the world

2012-09-01

Full Text Available Controversies, development and trends of biofuel industry in the world were discussed in present article. First-generation biofuels, i.e., grain and land based biofuels, occupied large areas of arable lands and severely constrained food supplies, are widely disputed. They have been replaced by second-generation biofuels. The raw materials of the second-generation biofuels include plants, straw, grass and other crops and forest residues. However, the cost for production of the second-generation biofuels is higher. Therefore the development of the third-generation biofuels is undergoing. The third-generation technologies use, mainly algae, as raw material to produce bioethanol, biobutanol, biodiesel and hydrogen, and use discarded fruits to produce dimethylfuran, etc. Different countries and regions are experiencing different stages of biofuel industry. In the future the raw materials for biofuel production will be focused on various by-products, wastes, and organisms that have not direct economic benefit for human. Production technologies should be improved or invented to reduce carbon emission and environmental pollution during biofuel production and to reduce production cost.

Vegetation Activity Trend and Its Relationship with Climate Change in the Three Gorges Area, China

Guifeng Han

2013-01-01

Full Text Available Based on SPOT/VGT NDVI time series images from 1999 to 2009 in the Three Gorges Area (TGA, we detected vegetation activity and trends using two methods, the Mann-Kendall and Slope tests. The relationships between vegetation activity trends and annual average temperature and annual total precipitation were analyzed using observational data in seven typical meteorological stations. Vegetation activity presents a distinctive uptrend during the study period, especially in Fengjie, Yunyang, Wushan, Wuxi, and Badong counties located in the midstream of the Three Gorges Reservoir. However, in the Chongqing major area (CMA and its surrounding areas and Fuling, Yichang, and part of Wanzhou, vegetation activity shows a decreasing trend as a result of urban expansion. The NDVI has two fluctuation troughs in 2004 and 2006. The annual mean temperature presents a slight overall upward trend, but the annual total precipitation does not present a significant trend. And they almost have no significant correlations with the NDVI. Therefore, temperature and precipitation are not major influences on vegetation activity change. Instead, increasing vegetation cover benefits from a number of environment protection policies and management, and ecological construction is a major factor resulting in the upward trend. In addition, resettlement schemes mitigate the impact of human activity on vegetation activity.

A summary of the most important data about the nuclear power reactors in operation and under construction as of the end of 1993 is given: their capacity, share of world capacity, growth of nuclear electricity generation since 1970 and its distribution by country. Nuclear prospects in the medium (2015) and long term (2025) are connected with a broad range of factors: development of advanced reactors ensuring high level of safety, implementation of high level waste repositories, enhancing the public acceptance of nuclear power. The issue of the cost of electricity generation is also discussed. Nuclear capacity projections to 2015 by region are given with 'low' and 'high' estimates. The low case reflects the continuation of the present trend of stagnation in nuclear power development due to public opposition and low economic growth in OECD countries, uncertainties in Eastern Europe and lack of finding in developing countries. The high case reflects a moderate revival of nuclear power development in the light of a more comprehensive assessment of the macro-economic and environmental aspects of the different options available for electricity generation. 7 figs., 5 tabs.

Internationally applied ecology was born around 25-40 years ago in order to adapt and serve the needs of mitigating increasingly environmental pollution and ecological destroy in developed western countries at that time. All the times applied ecological principles thus underpin most efforts at solving increasingly deterioration of natural resources and serious eco-environmental problems as its keystone and researching kernel with the development of the subject. At the advent of the 21st century, human beings enter into the age of applied ecology. There are five international features of applied ecology, including more attention to many-sided applications, special emphasis on the intersection with engineering, strongly keeping on mutual links with basic ecology, omnidirectional adoption of new methods and new technology, and side-by-side trends of microcosmic mechanisms and macroscopical regulation. Although we must connect with international applied ecology and absorb distillates from the subject in developed western countries, development of applied ecology in China in the future, in particular, at the beginnings of the 21st century should not deviate from aiming at the solution of increasingly environmental pollution and ecological destroy that is one of the most important basic situations of the country.

Flood is common in Pahang especially during northeast monsoon season from November to February. Three river cross station: Lubuk Paku, Sg. Yap and Temerloh were selected as area of this study. The stream flow and water level data were gathered from DID record. Data set for this study were analysed by using non-parametric analysis, Mann-Kendall Trend Test. The results that obtained from stream flow and water level analysis indicate that there are positively significant trend for Lubuk Paku (0.001) and Sg. Yap (<0.0001) from 1972-2011 with the p-value < 0.05. Temerloh (0.178) data from 1963-2011 recorded no trend for stream flow parameter but negative trend for water level parameter. Hydrological pattern and trend are extremely affected by outside factors such as north east monsoon season that occurred in South China Sea and affected Pahang during November to March. There are other factors such as development and management of the areas which can be considered as factors affected the data and results. Hydrological Pattern is important to indicate the river trend such as stream flow and water level. It can be used as flood mitigation by local authorities. (author)

The Abnormal Occurrences Reporting System of the Commission of the European Communities was developed by the Joint Research Centre at Ispra in the period 1982 through 1985. It collects in a unique format all safety relevant events from NPPs as recorded in the participating countries. The system has been set-up with the specific objective of providing an advanced tool for a synoptic analysis of a large number of events, identifying patterns of sequences, trends, multiple dependencies between incident descriptors, precursors to severe incidents, performance indicators etc. This paper gives an overview of the development of trend and pattern analysis techniques of two different types: - event sequence analysis; - statistical methods. Though these methods have been developed and applied in relation with the AORS data, they can be regarded as generic in the sense that they may be applied to any incident reporting system satisfying the necessary criteria as to homogeneity and completeness, for rendering valid results

2006-01-01

Full Text Available It is estimated that around 2.5 million people suffer from cancer at any given time in India. Almost 80% of patients reach hospitals in advanced stages of the disease. The majority needs palliative care, whereas only a minority of the needy receives this input. The challenge in the developing world is to evolve a culturally and socio-economically appropriate and acceptable system of care, while addressing psychosocial issues along with long-term care needs, that is accessible to the majority of those who need it. The evolution of a specific service for psychosocial care for persons and families started in the 1970s, initial work focusing mainly on research. Contributions from persons in varied topics have been outlined. Only a few organized clinical services function as part of large tertiary hospitals, oncology centers or palliative care units. The emerging trend in Northern Kerala is based on an integrated service linking training, clinical services and research activities which are linked at several levels, involving volunteers in the community. Future hopes lie in developing core groups; establishing specific clinical services liaising with cancer care teams, large scale research projects and discussion with policy makers to develop guidelines at national level.

Japanese government is carrying out the administrative reform aiming to promote decentralization of authority, to magnify the field of private sectors, etc. in order to corresponds appropriately to matured economy, internationalized market, etc. As one of the reforms, Japanese government decided that JAERI and JNC would unite into an independent administrative agency. The aims of the independent administrative agency institution include realization of effective and transparent system and management. The aim of the present investigation is to be useful for the new agency to develop a major business control system, which manages financial affairs and accounts not only efficiently but also in correspondence with open information to the public and promoting research activities effectively. First of all, the authors examined Japanese laws and standards relating to the independent administrative agency. They investigated the financial affairs and accounts systems of the preceding independent administrative agencies for research and development and also the development trends of work-flow systems in private enterprises in Japan. They considered expected problems and solutions for developing and making use of the major business control system. On the basis of the above investigations, the authors revealed the total concept of the best major business control system of the new unified agency besides the necessary conditions of the system for an independent administrative agency. Additionally, the above mentioned laws and standards are collected in an appendix. (author)

Search for major genes with progeny test data to accelerate the development of genetically superior loblolly pine

Energy Technology Data Exchange (ETDEWEB)

NCSU

2003-12-30

This research project is to develop a novel approach that fully utilized the current breeding materials and genetic test information available from the NCSU-Industry Cooperative Tree Improvement Program to identify major genes that are segregating for growth and disease resistance in loblolly pine. If major genes can be identified in the existing breeding population, they can be utilized directly in the conventional loblolly pine breeding program. With the putative genotypes of parents identified, tree breeders can make effective decisions on management of breeding populations and operational deployment of genetically superior trees. Forest productivity will be significantly enhanced if genetically superior genotypes with major genes for economically important traits could be deployed in an operational plantation program. The overall objective of the project is to develop genetic model and analytical methods for major gene detection with progeny test data and accelerate the development of genetically superior loblolly pine. Specifically, there are three main tasks: (1) Develop genetic models for major gene detection and implement statistical methods and develop computer software for screening progeny test data; (2) Confirm major gene segregation with molecular markers; and (3) Develop strategies for using major genes for tree breeding.

Ten years after "Worrying trends in econophysics": developments and current challenges

Science.gov (United States)

Ormerod, Paul

2016-12-01

Econophysics has made a number of important additions to scientific knowledge. Yet it continues to lack influence with both economists and policy makers. Ten years ago, I and three other economists sympathetic to econophysics wrote a paper on worrying trends within the discipline. For example, its lack of awareness of the economics literature, and shortfalls in the use of statistical analysis. These continue to be obstacles to wider acceptance by economists. Like all agents, policy makers respond to incentives, and economists understand this very well. Much of the econophysics community appears to think that simply doing good science is sufficient to have the work recognised, rather than relating to the motivations and incentives of policy makers. Nevertheless, econophysics now has three major opportunities to advance knowledge in areas where policy makers perceive weaknesses in what they are presented with by economists. All can benefit from the analysis of Big Data. The first is a core model of agent behaviour which is more relevant to cyber society than the rational agent model of economics. Second, extending our understanding of the business cycle, primarily by incorporating the importance of networks into models. Third, devising proper measures of output in cyber society.

AOD trends during 2001-2010 from observations and model simulations

The trend of aerosol optical depth (AOD) between 2001 and 2010 is estimated globally and regionally from remote sensed observations by the MODIS (Moderate Resolution Imaging Spectroradiometer), MISR (Multi-angle Imaging SpectroRadiometer) and SeaWIFS (Sea-viewing Wide Field-of-view Sensor) satellite sensor. The resulting trends have been compared to model results from the EMAC (ECHAM5/MESSy Atmospheric Chemistry {[1]}), model. Although interannual variability is applied only to anthropogenic and biomass-burning emissions, the model is able to quantitatively reproduce the AOD trends as observed by MODIS, while some discrepancies are found when compared to MISR and SeaWIFS. An additional numerical simulation with the same model was performed, neglecting any temporal change in the emissions, i.e. with no interannual variability for any emission source. It is shown that decreasing AOD trends over the US and Europe are due to the decrease in the (anthropogenic) emissions. On contrary over the Sahara Desert and the Middle East region, the meteorological/dynamical changes in the last decade play a major role in driving the AOD trends. Further, over Southeast Asia, both meteorology and emissions changes are equally important in defining AOD trends {[2]}. Finally, decomposing the regional AOD trends into individual aerosol components reveals that the soluble components are the most dominant contributors to the total AOD, as their influence on the total AOD is enhanced by the aerosol water content. {[1]}: Jöckel, P., Kerkweg, A., Pozzer, A., Sander, R., Tost, H., Riede, H., Baumgaertner, A., Gromov, S., and Kern, B.: Development cycle 2 of the Modular Earth Submodel System (MESSy2), Geosci.

Major trends in nuclear and coal fired plants economics

An in-depth analysis of nuclear plant performance in the United States and elsewhere raises basic questions as to the validity of the present pessimism as a guide for long-range policy. The sad story of the plants in trouble has obscured the good performance of the majority of nuclear power installations. Further, it appears that many of the root causes for the outstanding problems may be indigenous to the existing U.S. utility, regulatory, and financial structure, and not relevant to the long-range intrinsic values of nuclear power either in the United States or in other countries. On the other hand, many of the problems affecting coal fired plants, i.e., fuel supply, economics and pollution control appear to be more critical abroad rather than in the U.S. This paper will review these issues

Signal trend identification with fuzzy methods

A fuzzy-logic-based methodology for on-line signal trend identification is introduced. Although signal trend identification is complicated by the presence of noise, fuzzy logic can help capture important features of on-line signals and classify incoming power plant signals into increasing, decreasing and steady-state trend categories. In order to verify the methodology, a code named PROTREN is developed and tested using plant data. The results indicate that the code is capable of detecting transients accurately, identifying trends reliably, and not misinterpreting a steady-state signal as a transient one

In Central Asian foci of zoonotic cutaneous leishmaniases, mixed infections of Leishmania turanica and L. major have been found in a reservoir host (the great gerbil, Rhombomys opimus) as well as in the sand fly vector Phlebotomus papatasi, but hybrids between these two Leishmania species have never been reported. In addition, the role of sand fly species other than P. papatasi in L. turanica circulation is not clear. In this work we compared the development of L. turanica in three sand fly species belonging to different subgenera. In addition, we studied experimental co-infections of sand flies by both Leishmania species using GFP transfected L. turanica (MRHO/MN/08/BZ18(GFP+)) and RFP transfected L. major (WHOM/IR/-/173-DsRED(RFP+)). The possibility of Leishmania genetic exchange during the vectorial part of the life cycle was studied using flow cytometry combined with immunofluorescent microscopy. Late-stage infections of L. turanica with frequent colonization of the stomodeal valve were observed in the specific vector P. (Phlebotomus) papatasi and in the permissive vector P. (Adlerius) arabicus. On the other hand, in P. sergenti (the specific vector of L. tropica), L. turanica promatigotes were present only until the defecation of bloodmeal remnants. In their natural vector P. papatasi, L. turanica and L. major developed similarly, and the spatiotemporal dynamics of localization in the sand fly gut was the same for both leishmania species. Fluorescence microscopy in combination with FACS analyses did not detect any L. major / L. turanica hybrids in the experimental co-infection of P. papatasi and P. duboscqi. Our data provide new insight into the development of different leishmania parasite species during a mixed infection in the sand fly gut. Despite the fact that both Leishmania species developed well in P. papatasi and P. duboscqi and did not outcompete each other, no genetic exchange was found. However, the ability of L. turanica to establish late

In light of the commitments accepted within the Framework Convention on Climate Change there is an increasing need for useful information on energy consumption and energy efficiency. Governments can use this information in designing policies to reduce greenhouse gas emissions and prioritizing energy savings options. International comparison of energy efficiency can provide a benchmark against which a country's performance can be measured and policies can be evaluated. A methodology for international comparisons of industrial energy efficiency was developed by the International Network on Energy Demand analysis in the Industrial Sector. In this paper this methodology is used to analyze the energy efficiency of two energy-intensive industries in major developing countries. Energy consumption trends are shown for the steel and cement industry and an analysis is made of technologies used. In light of the Byrd-Hagel resolution, which states that the US will not ratify any climate treaty unless it also mandates commitments to limit greenhouse gas emissions for developing countries, the energy efficiency in the two sectors is compared to that of the US. The analysis shows that in the iron and steel sector South Korea and Brazil are more energy-efficient than the US, while Mexico has achieved a comparable energy efficiency level in recent years. For cement, South Korea, Brazil and Mexico are the most efficient countries analyzed. In recent years, China, and especially, India appear to have achieved energy efficiency levels, more or less comparable to that of the US. In light of data constraints, however, further analysis is required

Extraction of natural gas from tight shale formations has been made possible by recent technological advances, including hydraulic fracturing with horizontal drilling. Global shale gas development is seen as a potential energy and geopolitical "game-changer." However, widespread concern exists with respect to possible environmental consequences of this development, particularly impacts on water resources. In the United States, where the most shale gas extraction has occurred, the Marcellus Shale is now the largest natural gas producing play. To date, over 6,000,000 m(3) of wastewater has been generated in the process of extracting natural gas from this shale in the state of Pennsylvania (PA) alone. Here we examine wastewater management practices and trends for this shale play through analysis of industry-reported, publicly available data collected from the Pennsylvania Department of Environmental Protection Oil and Gas Reporting Website. We also analyze the tracking and transport of shale gas liquid waste streams originating in PA using a combination of web-based and GIS approaches. From 2008 to 2011 wastewater reuse increased, POTW use decreased, and data tracking became more complete, while the average distance traveled by wastewater decreased by over 30%. Likely factors influencing these trends include state regulations and policies, along with low natural gas prices. Regional differences in wastewater management are influenced by industrial treatment capacity, as well as proximity to injection disposal capacity. Using lessons from the Marcellus Shale, we suggest that nations, states, and regulatory agencies facing new unconventional shale development recognize that pace and scale of well drilling leads to commensurate wastewater management challenges. We also suggest they implement wastewater reporting and tracking systems, articulate a policy for adapting management to evolving data and development patterns, assess local and regional wastewater treatment

International trends in curriculum research

DEFF Research Database (Denmark)

Rasmussen, Jens

of the western school systems (especially within natural science and mathematics), the PISA-study has also been followed by school and curriculum radical reforms. The inspiration for the European reforms was taken in the so called accountability policy that during the 1990s had been developed in the USA...... is at the same time a centralization and a decentralization strategy: centralization at the input and the output side and decentralization of processes. The basic idea is that those responsible for the processes (principals and teachers) are held responsible for the outcomes. In the USA outcomes are related...... of their first generation goals as well of their national test systems. A trend in international school reform policy seems to be a break with the New Public Management and accountability philosophy that has played a major role over the last two decades. It is probably too early to say that these strategies...

Technology development brings sub-majors to N-power construction

International Nuclear Information System (INIS)

Anon.

1985-01-01

In the past, the construction works of almost all reactor buildings were carried out by big five companies, but as the number of joint venture projects increased, the way opened for submajor firms to participate in the construction of main nuclear buildings. When the five major companies alone engaged in the construction of nuclear plant buildings, three submajor firms did most of the civil engineering works needed. The civil engineering works have been carried out also as joint venture. In order to break through the big five barrier, submajor companies have been engaged in the independent and joint development of nuclear-related design and construction techniques, and the gap with major companies has been closing. The typical joint study done by seven submajor companies was on the load-deflection characteristics of building structures. Also they engaged in aseismatic studies. The method of stripping the contaminated surface layer of shielding concrete is a new technique studied by JAERI. The activities of eleven submajor companies are reported. (Kako, I.)

Projection display technology and product trends

Kahn, Frederic J.

1999-05-01

Major technology and market trends that could generate a 20 billion dollar electronic projector market by 2010 are reviewed in the perspective of recent product introductions. A log linear analysis shows that the light outputs of benchmark transportable data video projectors have increased at a rate of almost 90 percent per year since 1993. The list prices of these same projectors have decreased at a rate of over 40 percent per year. The tradeoffs of light output vs. resolution and weight are illustrated. Recent trends in projector efficacy vs. year are discussed. Lumen output per dollar of list price is shown to be a useful market metric. Continued technical advances and innovations including higher throughput light valve technologies with integrated drivers, brighter light source, field sequential color, integrated- and micro-optical components, and aerospace materials are likely to sustain these trends. The new technologies will enable projection displays for entertainment and computer applications with unprecedented levels of performance, compactness, and cost-effectiveness.

When following current advancements and implementations in the field of machine vision there seems to be no borders for future developments: Calculating power constantly increases, and new ideas are spreading and previously challenging approaches are introduced in to mass market. Within the past decades these advances have had dramatic impacts on our lives. Consumer electronics, e.g. computers or telephones, which once occupied large volumes, now fit in the palm of a hand. To note just a few examples e.g. face recognition was adopted by the consumer market, 3D capturing became cheap, due to the huge community SW-coding got easier using sophisticated development platforms. However, still there is a remaining gap between consumer and industrial applications. While the first ones have to be entertaining, the second have to be reliable. Recent studies (e.g. VDMA [1], Germany) show a moderately increasing market for machine vision in industry. Asking industry regarding their needs the main challenges for industrial machine vision are simple usage and reliability for the process, quick support, full automation, self/easy adjustment at changing process parameters, "forget it in the line". Furthermore a big challenge is to support quality control: Nowadays the operator has to accurately define the tested features for checking the probes. There is an upcoming development also to let automated machine vision applications find out essential parameters in a more abstract level (top down). In this work we focus on three current and future topics for industrial machine vision: Metrology supporting automation, quality control (inline/atline/offline) as well as visualization and analysis of datasets with steadily growing sizes. Finally the general trend of the pixel orientated towards object orientated evaluation is addressed. We do not directly address the field of robotics taking advances from machine vision. This is actually a fast changing area which is worth an own

To explore current trends in nursing theories through an integrated literature review. The literature related to nursing theories during the past 10 years was searched through multiple databases and reviewed to determine themes reflecting current trends in nursing theories. The trends can be categorized into six themes: (a) foci on specifics; (b) coexistence of various types of theories; (c) close links to research; (d) international collaborative works; (e) integration to practice; and (f) selective evolution. We need to make our continuous efforts to link research and practice to theories, to identify specifics of our theories, to develop diverse types of theories, and to conduct international collaborative works. Our paper gives implications for future theoretical development in diverse clinical areas of nursing research and practice. © 2012 Sigma Theta Tau International.

Full Text Available The current party system of Ukraine, defined its main features and trends with regard of parliamentary elections 2014 was investigated. The classification, which distinguish the parliamentary system was determined. It is established that the party system has undergone significant changes compared to previous years. Thus, according to classification Mayra Ukrainian party system evolved from a secondary party system to a system of small parties because the two largest parties have 47.5% of votes in parliament. Meyer’s Index fell by almost a factor of 2, indicating that the party system became more competitive, the process of forming a coalition will be longer, and the stability of the government will be lower than in previous years. The calculated effective indices of the number of parties suggested Laakso, Taagepera and Golosov also show that the party system became more fragmented. Based on the analyzed results of parliamentary elections for 1998­2014 years, it has found that increasing or decreasing the percentage threshold of 1%, not significantly affected by the number of parties represented in Parliament; none of the parties could not be present in every convocation; there is uncertainty in electoral preferences.

Underground coal mining - methods, equipment developments and trends

Energy Technology Data Exchange (ETDEWEB)

Singhal, R

1988-12-01

Underground mines are truly beginning to accept the so-called 'high tech' technology evident in other industries. Automation, remote control and robotics have taken an added significance. Wireless communication, mine-wide equipment health and performance monitoring, and transmission of data from deeper levels to surface is moving towards becoming the norm. There is emphasis on developing and applying continuous mining systems, as well as on modifying cyclical discontinuous methods to continuous systems. Multi-purpose equipment is also being developed. Technology transfer is playing its role - equipment and systems from surface coal mining are being applied to underground mining and vice-versa. At the American Mining Congress Exhibition held in Chicago in April 1988, a variety of equipment for underground mining was displayed including coal face equipment such as shearer loaders, conveyors and powered supports, and equipment for room-and-pillar coal mining. The trend continues to be towards high power machines equipped with a variety of electronics and sensors, safety devices, and alarm systems. Ancillary equipment on display covered a variety of cutting drums, cutting tools, conveying equipment and so on. In room-and-pillar mining, the overall emphasis was on moving away from the cyclical nature of the work. Transportation by shuttle cars must be replaced by continuous transport systems such as conveyors. Experience from Australia has shown that the application of continuous haulage and breaker line supports has permitted a doubling of production from room-and-pillar systems. Production levels of 3,000tpd have already been achieved, and 4,000tpd is considered achievable.

South Asia (SA) has been considered one of the most remarkable regions for changing vegetation greenness, accompanying its major expansion of agricultural activities, especially irrigated farming. The influence of the monsoon climate on the seasonal trends and anomalies of vegetation greenness is poorly understood in this area. Herein, we used the satellite-based Normalized Difference Vegetation Index (NDVI) to investigate various spatiotemporal patterns in vegetation activity during summer and winter monsoon (SM and WM) seasons and among irrigated croplands (IC), rainfed croplands (RC), and natural vegetation (NV) areas during 1982–2013. Seasonal NDVI variations with climatic factors (precipitation and temperature) and land use and cover changes (LUCC) have also been investigated. This study demonstrates that the seasonal dynamics of vegetation could improve the detailed understanding of vegetation productivity over the region. We found distinct greenness trends between two monsoon seasons and among the major land use/cover classes. Winter monsoons contributed greater variability to the overall vegetation dynamics of SA. Major greening occurred due to the increased productivity over irrigated croplands during the winter monsoon season; meanwhile, browning trends were prominent over NV areas during the same season. Maximum temperatures had been increasing tremendously during the WM season; however, the precipitation trend was not significant over SA. Both the climate variability and LUCC revealed coupled effects on the long term NDVI trends in NV areas, especially in the hilly regions, whereas anthropogenic activities (agricultural advancements) played a pivotal role in the rest of the area. Until now, advanced cultivation techniques have proven to be beneficial for the region in terms of the productivity of croplands. However, the crop productivity is at risk under climate change.

Since reconstruction of old town in Korea requires high-rise and seismic design construction, many attentions have been paid to high strength seismic reinforced steel bar. In the present paper, technical developments and trends are summarized for developing next-generation seismic reinforced steel bar of grade 700 MPa. Steelmaking process requires high energy efficiency and refining ability. Effects of alloying elements are explained, and alloy design based on computational thermodynamics is introduced. On the other hand, it is considered that grain size refinement by the controlled rolling and low temperature transformation structures formed by the accelerated cooling are effective to obtain acceptable mechanical properties with high strength. Finite element simulation analysis is also useful to understand plastic deformation by rolling, internal and external heat transfer, and corresponding phase transformation of austenite phase to various low-temperature transformation structures.

A model approach for analysing trends in energy supply and demand at country level: case study of industrial development in China

International Nuclear Information System (INIS)

Miranda-da-Cruz, S.M.

2007-01-01

Ideally, national energy supply and demand choices would be based on comprehensive models and predictions of the energy sources, energy transformations, energy carriers and energy end-uses expected to play major roles into the foreseeable future (20-40 years). However, in many cases, the necessary detailed, high quality, consistent and timely data is not available for such comprehensive models to be constructed, in particular in large and complex developing economies expected to be major energy users in the near future. In the developing countries that are the focus of UNIDO's work, attention has been concentrated on making progress simultaneously on two fronts: (a) a dramatic decrease in energy intensity, particularly in activities linked to industrial production and (b) a major increase in the contribution of local renewable energy to limit growth in fossil fuel use. National policies need to be oriented towards a strict and strategic monitoring of the respective energy matrices with a simultaneous focus on both fronts. Robust assessments of industrial development trends throughout the whole 20-40 year transition phase are needed to achieve both objectives. Until more comprehensive energy-related models can be built up, to overcome the limited availability of data at country level it is proposed that a simple energy supply and demand model analysis consisting of three phases be used for identifying the consistency of future scenarios and corresponding policy requirements. This model analysis, which is a dynamic exercise, consists, first, of an analysis at aggregate level of the current and future national energy matrices; secondly, an analysis of perspectives for decreasing the energy intensity of the most inefficient systems or industrial sectors; and thirdly, an analysis of perspectives for increasing the supply and cost-effectiveness of sustainable energy sources. As an illustration of this model approach, the case of China is analysed with emphasis on the

The Depression Inventory Development project is an initiative of the International Society for CNS Drug Development whose goal is to develop a comprehensive and psychometrically sound measurement tool to be utilized as a primary endpoint in clinical trials for major depressive disorder. Using an iterative process between field testing and psychometric analysis and drawing upon expertise of international researchers in depression, the Depression Inventory Development team has established an empirically driven and collaborative protocol for the creation of items to assess symptoms in major depressive disorder. Depression-relevant symptom clusters were identified based on expert clinical and patient input. In addition, as an aid for symptom identification and item construction, the psychometric properties of existing clinical scales (assessing depression and related indications) were evaluated using blinded datasets from pharmaceutical antidepressant drug trials. A series of field tests in patients with major depressive disorder provided the team with data to inform the iterative process of scale development. We report here an overview of the Depression Inventory Development initiative, including results of the third iteration of items assessing symptoms related to anhedonia, cognition, fatigue, general malaise, motivation, anxiety, negative thinking, pain and appetite. The strategies adopted from the Depression Inventory Development program, as an empirically driven and collaborative process for scale development, have provided the foundation to develop and validate measurement tools in other therapeutic areas as well.

2015-01-01

Over the past several decades, the world and most countries have undergone unprecedented demographic change. The most obvious example of this change is the rise in human numbers, and there are also important trends in fertility, family structure, mortality, migration, urbanization, and population aging. This paper summarizes past trends and projections in fertility and population. After reaching 2.5 billion in 1950, the world population grew rapidly to 7.2 billion in 2013 and the projections expect this total to be 10.9 billion by 2100. World regions differ widely in their demographic trends, with rapid population growth and high fertility continuing in the poorest countries, particularly in sub-Saharan Africa, while population decline, population aging, and very low fertility are now a key concern in many developed countries. These trends have important implications for human welfare and are of interest to policy makers. The conclusion comments briefly on policy options to address these adverse trends.

2017-12-01

Full Text Available Shortage of qualified staff and constant struggle for talents along with the retention of most valuable employees belong to the hottest personnel issues for the majority of organizations nowadays. HR marketing can significantly help in these areas. Within HR marketing human resources officers become those marketers who strive to keep their organization’s name in the minds of all stakeholders, thus drawing their attention to organization’s qualities as an employer, and in such a way winning by taking care of the most talented employees. The aim of this paper is to determine and evaluate the benefits resulting from employer branding and also to identify the trends conducive to the strengthening of an employer’s brand. The data were obtained using a questionnaire survey (n = 492 in the selected Czech organizations. The results show that employer branding is an important element in all economic sectors and businesses can build their brands by focusing primarily on the stability of their current employees, their continuous development and their retaining of the most valuable knowledge. The article focuses on new strategic trends in building employer’s good brand and attracting the most knowledgable workers.

Major environmental issues that are likely to affect the implementation of energy technologies between now and the year 2000 are identified and assessed. The energy technologies specifically addressed are: oil recovery and processing; gas recovery and processing; coal liquefaction; coal gasification (surface); in situ coal gasification; direct coal combustion; advanced power systems; magnetohydrodynamics; surface oil shale retorting; true and modified in situ oil shale retorting; geothermal energy; biomass energy conversion; and nuclear power (fission). Environmental analyses of these technologies included, in addition to the main processing steps, the complete fuel cycle from resource extraction to end use. A comprehensive survey of the environmental community (including environmental groups, researchers, and regulatory agencies) was carried out in parallel with an analysis of the technologies to identify important future environmental issues. Each of the final 20 issues selected by the project staff has the following common attributes: consensus of the environmental community that the issue is important; it is a likely candidate for future regulatory action; it deals with a major environmental aspect of energy development. The analyses of the 20 major issues address their environmental problem areas, current regulatory status, and the impact of future regulations. These analyses are followed by a quantitative assessment of the impact on energy costs and nationwide pollutant emissions of possible future regulations. This is accomplished by employing the Strategic Environmental Assessment System (SEAS) for a subset of the 20 major issues. The report concludes with a more general discussion of the impact of environmental regulatory action on energy development.

20 year long term air quality trends in Israel

Science.gov (United States)

Luria, M.

2017-12-01

The Israeli air monitoring network was established in the mid 1990's with dozens of measuring sites near most populated areas. During these past 20 years the Israel economy has increased significantly. The population grew by 30%, energy consumption and power generation by more than 40% and the number of motor vehicles increased by nearly 50%. Most of the fossil energy is consumed by the electric power industry that has changed immensely during this period. Until the early 2000's the vast majority of the electricity was generated from coal and heavy oil. However, during the last ten years natural gas has gradually becomes the major source for power generation and for most of the heavy industry. In the present study we examined the impact of these economic trends on the major criteria air pollution parameters; O3, NOx, SO2 and PM10. The analyses was based on the long term trend of median value (50th percentile) and the 90th percentile. The results revealed that SO2 levels throughout the country decreased to very low levels, with the 90th percentile near the detection limit. The levels of PM10, that are relatively high compare with other global regions, did not show any trend during the 20 year period. This is consistent with the fact that most particulate matter results from long range transport of dust from the surrounding deserts. The long term trend of NOx indicates a gradual and steady increase at most measuring sites, which is consistent with the increase of fossil fuel consumption. The increase in NOx levels is most likely the cause for the significant increase in O3 levels found at most sites in a few of them to levels that are considered as an environmental hazard.

Alberta air emissions : trends and projections

International Nuclear Information System (INIS)

2008-06-01

This paper provided a summary of air emissions trends and projections for Alberta. Predicted regional distribution trends and industry sector emissions were presented. Historical and projected emissions included sulfur oxides (SO x ) nitrogen oxide (NO x ), volatile organic compounds (VOCs), and ammonia (NH 3 ). Results of the study indicated that carbon monoxide (CO) emissions were decreasing, while VOCs, NO x , SO x , PM 2.5 and NH 3 levels were increasing. Approximately 9 per cent of ammonia emissions were from point sources, while the majority of PM 2.5 emissions were attributed to unpaved roads and construction operations. Agricultural animal operations accounted for most of the VOC source emissions in the region. Increased development of the oil sands industry is contributing to increases in VOC emissions. Increases in NH 3 were attributed to growth in the agricultural sector and the increasing use of confined feeding operations in the region. Results of the study indicated that greenhouse gas (GHG) emissions in Alberta will keep increasing as a result of Alberta's growing economy. It was concluded that emissions from other industrial sectors are also expected to increase. In 2005, Alberta's total GHG emissions were 233 megatonnes of CO 2 equivalent, of which 168 megatonnes were attributed to industry. Results were presented in both graph and tabular formats. 3 tabs., 25 figs

Analysis of gravity data using trend surfaces

2013-04-01

In this paper we have developed algorithms and related software programs for calculating of trend surfaces of higher order. These methods of analysis of trends, like mobile media applications are filtration systems for geophysical data in surface. In particular we presented few case studies for gravity data and gravity maps. Analysis with polynomial trend surfaces contributes to the recognition, isolation and measurement of trends that can be represented by surfaces or hyper-surfaces (in several sizes), thus achieving a separation in regional variations and local variations. This separation is achieved by adjusting the trend function at different values. Trend surfaces using the regression analysis satisfy the criterion of least squares. The difference between the surface of trend and the observed value in a certain point is the residual value. Residual sum of squares of these values should be minimal as the criterion of least squares. The trend surface is considered as regional or large-scale and the residual value will be regarded as local or small-scale component. Removing the regional trend has the effect of highlighting local components represented by residual values. Surface analysis and hyper-surfaces principles are applied to the surface trend and any number of dimensions. For hyper-surfaces we can work with polynomial functions with four or more variables (three variables of space and other variables for interest parameters) that have great importance in some applications. In the paper we presented the mathematical developments about generalized trend surfaces and case studies about gravimetric data. The trend surfaces have the great advantage that the effect of regional anomalies can be expressed as analytic functions. These tendency surfaces allows subsequent mathematical processing and interesting generalizations, with great advantage to work with polynomial functions compared with the original discrete data. For gravity data we estimate the depth of

Models of reliability growth relate current system unreliability to currently accumulated experience. But “experience” comes in different forms. Looking back after a major accident, one is sometimes able to identify previous events or measurable performance trends that were, in some sense, signaling the potential for that major accident: potential that could have been recognized and acted upon, but was not recognized until the accident occurred. This could be a previously unrecognized cause of accidents, or underestimation of the likelihood that a recognized potential cause would actually operate. Despite improvements in the state of practice of modeling of risk and reliability, operational experience still has a great deal to teach us, and work has been going on in several industries to try to do a better job of learning from experience before major accidents occur. It is not enough to say that we should review operating experience; there is too much “experience” for such general advice to be considered practical. The paper discusses the following: 1. The challenge of deciding what to focus on in analysis of operating experience. 2. Comparing what different models of learning and reliability growth imply about trending and precursor analysis.

Recent Trends in Therapeutic Approaches for Diabetes Management: A Comprehensive Update

Full Text Available Diabetes highlights a growing epidemic imposing serious social economic crisis to the countries around the globe. Despite scientific breakthroughs, better healthcare facilities, and improved literacy rate, the disease continues to burden several sections, especially middle and low income countries. The present trends indicate the rise in premature death, posing a major threat to global development. Scientific and technological advances have witnessed the development of newer generation of drugs like sulphonylureas, biguanides, alpha glucosidase inhibitors, and thiazolidinediones with significant efficacy in reducing hyperglycemia. Recent approaches in drug discovery have contributed to the development of new class of therapeutics like Incretin mimetics, Amylin analogues, GIP analogs, Peroxisome proliferator activated receptors, and dipeptidyl peptidase-4 inhibitor as targets for potential drugs in diabetes treatment. Subsequently, the identification and clinical investigation of bioactive substances from plants have revolutionized the research on drug discovery and lead identification for diabetes management. With a focus on the emerging trends, the review article explores the current statistical prevalence of the disease, discussing the benefits and limitations of the commercially available drugs. Additionally, the critical areas in clinical diabetology are discussed, with respect to prospects of statins, nanotechnology, and stem cell technology as next generation therapeutics and why the herbal formulations are consistently popular choice for diabetes medication and management.

2015-11-01

Healthier food initiatives conducted by national food retailers may offer opportunities to improve the nutritional profile of food purchases. Using a longitudinal data set of packaged food purchases made by US households, we examined the effect of a healthier food initiative officially launched by Walmart in 2011. From 2000 to 2013, household-level purchases of packaged foods at Walmart showed major declines in energy, sodium, and total sugar density, as well as in quantities of sugary beverages, grain-based desserts, snacks, and candy. These trends in packaged food purchases were more pronounced than similar concurrent trends seen at other major food retailers. However, the declines seen at Walmart after the initiative's official implementation did not exceed what would have been expected had pre-implementation trends continued, and therefore they cannot be attributed to the initiative. These results suggest that food retailer-based initiatives that purportedly create a healthier food environment may not suffice to improve the nutritional profile of food purchases. More systemic shifts in consumers' characteristics and preferences may be needed. Project HOPE—The People-to-People Health Foundation, Inc.

Climate change and transnational corporations. Analysis and trends

International Nuclear Information System (INIS)

1992-01-01

In Economic and Social Council resolution 1989/25, the Council requested an analytic study of the main sectors of activity that have adverse effects on environmental preservation and the factors that determine the allocation of activities between developed and developing countries. The present report, entitled Climate Change and Transnational Corporations: Analysis and Trends, is in response to that request. The problem of global warming and the dangers it presents to global survival are being given high priority by the United Nations. Discussions are under way leading to a convention on global climate change under the auspices of United Nations intergovernmental bodies. The study was designed as a contribution to that process. It focuses on six transnational energy-producing and energy-consuming industrial sectors, in which corporate practices have a direct and major impact on the problems associated with global climate change. The sectors are fossil fuel production, transportation, electricity-generation, energy-intensive metals production, chlorofluorocarbons and other ozone-depleting chemicals, and inorganic nitrogen fertilizers. The study explores the relative differential impacts between industrialized and developing countries of each sector, and asks how each sector would have to be restructured in order to limit global climate change and ozone depletion. It concludes that major changes in the technical processes and investment patterns of the transnational corporations in those sectors would be necessary if catastrophic environmental changes are to be avoided

Research interests in addressing construction and demolition (C and D) waste management issues have resulted in a large amount of publications during the last decade. This study demonstrates that there is no systematic examination on the research development in literature in the discipline of C and D waste management. This study presents the latest research trend in the discipline through analyzing the publications from 2000 to 2009 in eight major international journals. The analysis is conducted on the number of papers published annually, main authors' contributions, research methods and data analysis methods adopted, and research topics covered. The results exhibit an increasing research interest in C and D waste management in recent years. Researchers from developed economies have contributed significantly to the development of the research in the discipline. Some developing countries such as Malaysia and China have also been making good efforts in promoting C and D waste management research. The findings from this study also indicate that survey and case study are major methods for data collection, and the data are mostly processed through descriptive analysis. It is anticipated that more future studies on C and D waste management will be led by researchers from developing economies, where construction works will remain their major economic activities. On the other hand, more sophisticated modeling and simulating techniques have been used effectively in a number of studies on C and D waste management research, and this is considered a major methodology for future research in the discipline. C and D waste management will continue to be a hot research topic in the future, in particularly, the importance of human factors in C and D waste management has emerged as a new challenging topic.

Full Text Available The implementation of modern banking activities involves the realization of investments. Investment is a complex discussion economic category, characterized by a number of features. The types and forms of investment are manifold and can be transformed with account of the state of the economy and the level of development of industrial relations. The faster growth of the financial sector in the economy has stipulated the development of financial investment. Banks as financial and lending institutions actively make financial investments in securities. Banks’ investment in securities pursues a number of purposes which determine the selection of securities for investment and their quality. The article identified the targets of bank investments in securities and their development trends under current conditions on the basis of the analysis of the actual data for 2010–2014. Negative revaluation and the actual decrease in the value of corporate securities of Russian issuers reduce their commercial appeal. Banks refuse to speculate on the stock market in favor of the securities that ensure liquidity. Banks’ investments aim to purchasing securities from the Lombard List of the Bank of Russia in order to obtain loans and participate in the repo transactions. Thus, during the analyzed period, banks’ investments in securities transformed from systemically important assets that generate substantial profit into the mechanism that provides liquidity. It should be noted that a significant part of investment resources of Russian banks services the debt obligations of Russia’s Government. The article also identified a trend of banks’ increasing investment in the participation portfolios of subsidiaries and associated joint stock companies. The official data of the Central Bank of the Russian Federation (Bank of Russia [15], and the Federal State Statistics Service [14] were used as the information base for the study

Utility involvement in uranium exploration and development - a growing trend

International Nuclear Information System (INIS)

Sullivan, R.P.; Riedel, D.W.

1980-01-01

Nuclear power commitments by United States utilities at the beginning of 1979 represent 137,000 MW(e) of capacity from 147 nuclear units scheduled for operation by 1985 plus an additional 52,000 MW(e) from 48 units scheduled beyond 1985. Including the minority owners there are over 100 independent electric utilities in the United States of America with some financial commitment to these 195 nuclear power plants. United States uranium requirements to the year 2000 have been projected at 35 to 40% of the world requirements (exclusive of centrally planned economies). Also United States uranium resources represent a substantial fraction of present estimated world resources. Thus, decisions by US electric utilities regarding their financial involvement in uranium exploration and development can be expected to have a large impact on the development of the world-wide uranium industry. Unlike the situation in most countries with large commitments to nuclear power, the US government is not directly involved financially in uranium exploration and development except in a supportive role to the industry as a whole. Investment decisions by US utilities and US mining companies are based on their individual perceptions of the risks and benefits to be gained. Public attitudes towards nuclear power and public regulatory commission treatment of utility expenditures for resource development vary throughout the country. Thus, US utilities have shown a wide range of responses in formulating their uranium procurement strategies. About half the utilities with nuclear commitments are at present involved financially in uranium exploration and development. This paper traces the development of this trend and elaborates on the types of financial involvement and the factors that affect a utility's selection of its overall uranium procurement strategy

Third molars are one of the few biological markers available for age estimation in undocumented juveniles close the legal age of majority, assuming an age of 18years as the most frequent legal demarcation between child and adult status. To obtain more accurate visualization and evaluation of third molar mineralization patterns from computed tomography images, a new software application, DentaVol©, was developed. Third molar mineralization according to qualitative (Demirjian's maturational stage) and quantitative parameters (third molar volume) of dental development was assessed in multi-slice helical computed tomography images of both maxillary arches displayed by DentaVol© from 135 individuals (62 females and 73 males) aged between 14 and 23years. Intra- and inter-observer agreement values were remarkably high for both evaluation procedures and for all third molars. A linear correlation between third molar mineralization and chronological age was found, with third molar maturity occurring earlier in males than in females. Assessment of dental development with both procedures, by using DentaVol© software, can be considered a good indicator of age of majority (18years or older) in all third molars. Our results indicated that virtual computed tomography imaging can be considered a valid alternative to orthopantomography for evaluations of third molar mineralization, and therefore a complementary tool for determining the age of majority.

MODERN TRENDS IN THE DEVELOPMENT OF THE TECHNOLOGIES FOR PRODUCTION OF DENTAL CONSTRUCTIONS.

Directory of Open Access Journals (Sweden)

Tsanka Dikova

2015-12-01

Full Text Available The aim of the present paper is to make a review of the modern trends in the development of the technologies for production of dental constructions. Three are the main trends in production technologies in dentistry last 30 years: digitalization, simulation and implementation of additive technologies. The simulation occurred first and due to the computers development it underwent fast progress from the mathematical calculations and analytical analysis to the 3D modeling and visualization. Thus Computer Aided Engineering (CAE was developed, allowing dental constructions with optimal design to be produced by optimal technological regimes. The first Computer Aided Design (CAD – Computer Aided Manufacturing (CAM systems were created in 1970s as a result of the digitalization. In this mode of operation at first virtual 3D model is generated by CAD, which then is used for production of the real construction by CAM. The CAD-CAM systems allow fabrication of dental restorations which is difficult or impossible to be manufactured by conventional technologies. The development of CAD unit runs from indirect scanning of the plaster model for obtaining data for the 3D model to direct scanning of the prosthesis area. While the development of CAM unit leads to direct manufacturing of the real dental construction using subtractive or additive technologies. The future development of the CAD-CAM systems as a whole characterizes with transition from closed to open access systems, which make them more flexible. In the late 1980sthe new approach to the production of constructions appeared – by addition of material layer by layer. The additive technologies were developed. They characterize with building of one layer at a time from a powder or liquid that is bonded by means of melting, fusing or polymerization. Stereo lithography, fused deposition modeling, selective electron beam melting, laser powder forming and inkjet printing are the methods, mostly used in

This volume consists of a selection of papers presented at the International Conference on Applied General Systems Research: Recent Developments and Trends which was held on the campus of the State University of New York at Binghamton in August 15-19, 1977, under the sponsorship of the Special Panel on Systems Science of the NATO Scientific Affairs Division. General systems research is a fairly new field which has been developing in the course of the last two or three decades. In my op~n10n, it can be best described as a movement which involves the study of all structural and context independent aspects of problem solving. As such, it is cross-disciplinary in nature and, in this sense, it might seem similar to mathematics. There is a consid­ erable difference, however, between the two. While pure mathe­ matics is basically oriented to the development of various axiomatic theories, regardless of whether or not they have any real world meaning, applied mathematics explores the applicability of some of these t...

This study describes key population health concepts and examines major empirical trends in US health and healthcare inequalities from 1935 to 2016 according to important social determinants such as race/ethnicity, education, income, poverty, area deprivation, unemployment, housing, rural-urban residence, and geographic location. Long-term trend data from the National Vital Statistics System, National Health Interview Survey, National Survey of Children's Health, American Community Survey, and Behavioral Risk Factor Surveillance System were used to examine racial/ethnic, socioeconomic, rural-urban, and geographic inequalities in health and health care. Life tables, age-adjusted rates, prevalence, and risk ratios were used to examine health differentials, which were tested for statistical significance at the 0.05 level. Life expectancy of Americans increased from 69.7 years in 1950 to 78.8 years in 2015. However, despite the overall improvement, substantial gender and racial/ethnic disparities remained. In 2015, life expectancy was highest for Asian/Pacific Islanders (87.7 years) and lowest for African-Americans (75.7 years). Life expectancy was lower in rural areas and varied from 74.5 years for men in rural areas to 82.4 years for women in large metro areas, with rural-urban disparities increasing during the 1990-2014 time period. Infant mortality rates declined dramatically during the past eight decades. However, racial disparities widened over time; in 2015, black infants had 2.3 times higher mortality than white infants (11.4 vs. 4.9 per 1,000 live births). Infant and child mortality was markedly higher in rural areas and poor communities. Black infants and children in poor, rural communities had nearly three times higher mortality rate compared to those in affluent, rural areas. Racial/ethnic, socioeconomic, and geographic disparities were particularly marked in mortality and/or morbidity from cardiovascular disease, cancer, diabetes, COPD, HIV/AIDS, homicide

Statistical tests used included chi-square and the chi-square test for trend to evaluate differences between susceptibility rates among age groups and ordering in the E. coli resistance rates per year, respectively. RESULTS: There were 37,261 positive results with Enterobacteriaceae isolated in 32,530 (87.3% and Gram-positive cocci in 2,570 (6.9% cultures. E. coli had the highest prevalence (71.6%. Susceptibility tests were performed in 31,716 cultures. E. coli had elevated resistance rates (> 30% to ampicillin, trimethoprim-sulfamethoxazole, and tetracycline. Significant differences between age groups and ordering among years were observed. CONCLUSIONS: The use of trimethoprim-sulfamethoxazole is precluded in the population studied due to elevated resistance rates (> 30% among most prevalent pathogens. Significant resistance rate differences among age groups and years were observed, particularly for fluoroquinolones. Fluoroquinolones should be used with caution. Nitrofurantoin should be used as empirical therapy for primary, non-complicated urinary tract infections.

Development of an Interdisciplinary Undergraduate Major in The Earth System, Environment and Society

Humanity faces great challenges in the 21st Century to understand and limit our impact on the Earth System. To address these challenges, it is essential to understand the nature and implications of environmental change, and the complexity of the Earth system. We need to educate citizens that have the background to make new developments in understanding technical aspects of the Earth System, and to develop an understanding the interactions between society and the Earth System sufficient to make informed policy choices. Traditional disciplinary departments and majors don't fully address this; teaching and research talent in the study of the Earth System is spread over many disciplinary-oriented departments. At the University of Illinois, we are currently developing a new cross-disciplinary undergraduate major being called The Earth system, environment and Society. This development is co-sponsored by a number of departments centered in the College of Liberal Arts & Sciences (but including other departments throughout the university). Our intention is that this major will be a catalyst for bringing together the many disciplines involved in Earth System Science education. The curriculum and course for study will focus on the science and human dimensions of the Earth system, with special emphasis on the processes and issues related to the environment across a range of spatial scales from local and regional to global. Along with meeting the requirements expected of all students in a liberal arts and sciences major, students in The Earth System, Environment and Society major will be required to complete a core set of courses designed to introduce students to all of the different components of the Earth System (students will choose from course options in both the sciences and the social sciences). After completing the core courses, students will then focus their studies on one of the two options within the major, Science of the Earth System (this option will emphasize the

Despite wide variations in hip rates fractures worldwide, reasons for such differences are not clear. Furthermore, secular trends in the age-specific hip fracture rates are changing the world map of this devastating disease, with the highest rise projected to occur in developing countries. The aim of our investigation is to systematically characterize secular trends in hip fractures worldwide, examine new data for various ethnic groups in the United States, evidence for divergent temporal patterns, and investigate potential contributing factors for the observed change in their epidemiology. All studies retrieved through a complex Medline Ovid search between 1966 and 2013 were examined. For each selected study, we calculated the percent annual change in age-standardized hip fracture rates de-novo. Although occurring at different time points, trend breaks in hip fracture incidence occurred in most Western countries and Oceania. After a steep rise in age-adjusted rates in these regions, a decrease became evident sometimes between the mid-seventies and nineties, depending on the country. Conversely, the data is scarce in Asia and South America, with evidence for a continuous rise in hip fracture rates, with the exception of Hong-Kong and Taiwan that seem to follow Western trends. The etiologies of these secular patterns in both the developed and the developing countries have not been fully elucidated, but the impact of urbanization is at least one plausible explanation. Data presented here show close parallels between rising rates of urbanization and hip fractures across disparate geographic locations and cultures. Once the proportion of the urban population stabilized, hip fracture rates also stabilize or begin to decrease perhaps due to the influence of other factors such as birth cohort effects, changes in bone mineral density and BMI, osteoporosis medication use and/or lifestyle interventions such as smoking cessation, improvement in nutritional status and fall

Rainfall series at 18 stations along the major rivers of the Brazilian Amazon Basin, having data since 1920s or 1930s, are analyzed to verify if there are appreciable long-term trends. Annual, rainy-season, and dry-season rainfalls are individually analyzed for each station and for the region as a whole. Some stations showed positive trends and some negative trends. The trends in the annual rainfall are significant at only six stations, five of which reporting increasing trends (Barcelos, Belem, Manaus, Rio Branco, and Soure stations) and just one (Itaituba station) reporting decreasing trend. The climatological values of rainfall before and after 1970 show significant differences at six stations (Barcelos, Belem, Benjamin Constant, Iaurete, Itaituba, and Soure). The region as a whole shows an insignificant and weak downward trend; therefore, we cannot affirm that the rainfall in the Brazilian Amazon basin is experiencing a significant change, except at a few individual stations. Subregions with upward and downward trends are interspersed in space from the far eastern Amazon to western Amazon. Most of the seasonal trends follow the annual trends, thus, indicating a certain consistency in the datasets and analysis.

1993-01-01

Recently, the heightening of fuel burnup has been actively advanced internationally. Its degree is different according to the policy and the economical factors in respective countries. The extension of the period of operation cycle urges high burnup in view of economy. The circumstances in USA, Europe and Japan are explained. The corrosion of zircaloy cladding is the factor of limiting fuel life. The state of corrosion in reactors is different in BWRs and PWRs, and both cases are explained. The emission of FP gas from pellets to fuel rods raises the internal pressure of the fuel rods, and affects the gap conductance between pellets and cladding tubes. In the fuel for LWRs, plutonium is formed locally and burns in pellet rim part. This rim effect is discussed. The irradiation growth of fuel rods, creep down and pellet-cladding interaction are explained. The MOX fuel for LWRs and the trend of development of new type fuel are reported. The fuel for BWRs of Hitachi Ltd. and Toshiba Corp. and Nuclear Fuel Industries Ltd., the fuel for PWRs of Mitsubishi Heavy Industries Ltd. and Nuclear fuel Industries Ltd., and the recent development of the fuel cladding tubes for LWRs are described.

Full Text Available Background. Several guidelines for Parkinson’s disease (PD management were recently updated. We examined temporal trends for antiparkinsonism drugs in Taiwan. Methods. Antiparkinsonism prescriptions, including levodopa, ergot/nonergot dopamine agonists (DAs, amantadine, selegiline, entacapone, and anticholinergics, were identified in the Taiwan National Health Insurance Database from 2004 to 2011. Time trend analyses were estimated assuming Poisson distribution. Results. A total of 19,302 PD patients in 2004 and 41,606 PD patients in 2011 were analyzed. Antiparkinsonism prescriptions increased significantly from 187,137 in 2004 to 414,587 in 2011. Levodopa monotherapy or combination therapy was the mainstay. Levodopa monotherapy comprised 37.4% of prescriptions in 2004 and 44.2% in 2011, with an annual increase rate of 18.14%. There was a substantially increasing trend of DA prescriptions, which were higher in younger-aged patients (<60 years than in older-aged group (p=0.0006. Among combination therapy, DA combined with levodopa or other antiparkinsonism medications became the main combinations for younger-aged patients after 2009. After 2005, the proportion of ergot DA usage markedly decreased and PD patients using nonergot DA increased. Conclusions. Levodopa was the major treatment from 2004 to 2011. There was a steeply increased trend of DA use, especially in younger-aged patients. Nonergot agents comprised the major DA group after 2005.

2014-03-01

Full Text Available While there have been very limited studies of the educational computing literature to analyze the research trends since the early emergence of educational computing technologies, the authors argue that it is important for both researchers and educators to understand the major, historical educational computing trends in order to inform understandings of current and future eLearning trends. This study provides the findings of an analysis of 2,694 journal articles published between 1977 and 2005 in four major, international educational computing journals. It provides the platform for a subsequent analysis for the period 2006–2014 and beyond, as future educational computing research is published. The journal articles analyzed were categorized according to their research themes. Subsequently, clustering analysis, multi-dimension scale analysis, and research diversity analysis were performed on the categorized results to explore the research trends. The research literature analysis confirmed that there were identifiable evolutionary trends dating from 1977, and, importantly, the analysis highlighted that each key breakthrough in technology was accompanied by increased educational research about those technologies to inform educational practices. Importantly, two major driving forces of the historical trends identified were technologies and pedagogical approaches. The paper concludes with explanations of how these trends from 1977–2005 have shaped the current focus on Technological Pedagogical Content Knowledge (TPACK needed for effective current and future eLearning.

In a recent international meeting, five radioactive waste disposal organizations (NUMO/Japan; NAGRA/Switzerland; ONDRAF/NIRAS/Belgium; POSIVA/Finland; SKB/Sweden) have discussed the status and developments of RMS in their respective programs. The majority have already implemented an IT-based system, or, are testing and developing such systems. The level of detail of requirements depends on the stage of the program. Those approaching the license application have integrated all components of the repository concept, including the processes for the operational phase. Requirements management is closely associated with the quality management system. Combining requirement and decision-tracking has been expressed as an explicit goal for some programs. Caution was expressed regarding the expectations for the RMS being developed. There is a risk that such systems are perceived as expert systems that can derive decisions, which then will be unquestionably accepted. It is nevertheless recognized that they can be of great help in communicating with the various stakeholders and with relative ease demonstrate how their requirements have been considered and satisfied with the proposed repository systems. Further efforts need to be undertaken to integrate the requirement management systems, and the processes that they represent, in the day-to-day operations of the organizations. First positive experiences of the latter are reported. (author)

Phosphorus Loadings to the World's Largest Lakes: Sources and Trends

Science.gov (United States)

Fink, Gabriel; Alcamo, Joseph; Flörke, Martina; Reder, Klara

2018-04-01

Eutrophication is a major water quality issue in lakes worldwide and is principally caused by the loadings of phosphorus from catchment areas. It follows that to develop strategies to mitigate eutrophication, we must have a good understanding of the amount, sources, and trends of phosphorus pollution. This paper provides the first consistent and harmonious estimates of current phosphorus loadings to the world's largest 100 lakes, along with the sources of these loadings and their trends. These estimates provide a perspective on the extent of lake eutrophication worldwide, as well as potential input to the evaluation and management of eutrophication in these lakes. We take a modeling approach and apply the WorldQual model for these estimates. The advantage of this approach is that it allows us to fill in large gaps in observational data. From the analysis, we find that about 66 of the 100 lakes are located in developing countries and their catchments have a much larger average phosphorus yield than the lake catchments in developed countries (11.1 versus 0.7 kg TP km-2 year-1). Second, the main source of phosphorus to the examined lakes is inorganic fertilizer (47% of total). Third, between 2005-2010 and 1990-1994, phosphorus pollution increased at 50 out of 100 lakes. Sixty percent of lakes with increasing pollution are in developing countries. P pollution changed primarily due to changing P fertilizer use. In conclusion, we show that the risk of P-stimulated eutrophication is higher in developing countries.

Sphagnum peatland development at their southern climatic range in West Siberia: trends and peat accumulation patterns

Peregon, Anna; Uchida, Masao; Shibata, Yasuyuki

2007-01-01

A region of western Siberia is vulnerable to the predicted climatic change which may induce an important modification to the carbon balance in wetland ecosystems. This study focuses on the evaluation of both the long-term and contemporary trends of peat (carbon) accumulation and its patterns at the southern climatic range of Sphagnum peatlands in western Siberia. Visible and physical features of peat and detailed reconstructions of successional change (or sediment stratigraphies) were analysed at two types of forest-peatland ecotones, which are situated close to each other but differ by topography and composition of their plant communities. Our results suggest that Siberian peatlands exhibit a general trend towards being a carbon sink rather than a source even at or near the southern limit of their distribution. Furthermore, two types of peat accumulation were detected in the study area, namely persistent and intermittent. As opposed to persistent peat accumulation, the intermittent one is characterized by the recurrent degradation of the upper peat layers at the marginal parts of raised bogs. Persistent peat accumulation is the case for the majority of Sphagnum peatlands under current climatic conditions. It might be assumed that more peat will accumulate under the 'increased precipitation' scenarios of global warming, although intermittent peat accumulation could result in the eventual drying that may change peatlands from carbon sinks to carbon sources

In the past three decades, China has become a major contributor to science and technology. China now employs an increasingly large labor force of scientists and engineers at relatively high earnings and produces more science and engineering degrees than the United States at all levels, particularly bachelor's. China's research and development expenditure has been rising. Research output in China has been sharply increasing since 2002, making China the second largest producer of scientific papers after the United States. The quality of research by Chinese scientists has also been improving steadily. However, China's rise in science also faces serious difficulties, partly attributable to its rigid, top-down administrative system, with allegations of scientific misconduct trending upward.

Full Text Available The article is aimed at analyzing the nature and contemporary trends of foreign trade activity of France. In the process of evolutionary development of the economy of France in content, structure and directions of its foreign trade strategies occurred permanent modifications and transformations, resulting from the need to maintain optimal proportions between material, financial and human resources, production and consumption, commodity supply and purchasing power, as well as receipts and payments in the settlements with other countries. The article is concerned with an integrated analysis of progressive structural reforms in the economic system of France in the last decade, which led to fundamental changes in its foreign trade operations both in terms of monetary magnitude of export-import transactions and their product-species, geographical, institutional and regulatory structures. The nature, key indicators, trends and issues in the foreign trade strategy of France in the face of global volatility as well as ways for its improvement have been researched.

TRENDS IN THE DEVELOPMENT OF ORGANIC FARMING IN BULGARIA

Full Text Available The purpose of this article is to follow trends in the development of organic farming in Bulgaria, and to identify the factors’ strength and direction of their impact on organic production of agricultural products. The study covers the period from 2003 to 2013 and is based on information from official statistics of the Ministry of Agriculture and Food, and the author's own research. There are distinct rates of increase in both areas and organic agricultural production in Bulgaria. While in 2003 the areas under organic management are 8,364 ha by 2013 they numbered 56, 287 ha. Bulgaria has a high potential for production and export of organic agricultural products fresh and processed, but significantly lags behind other European countries. However, there is increasing momentum in organic farming, driven by a group of economic, market, social and legislative initiatives. The main reason for this growth is consumer demand of organic products in Bulgaria. In general, the motivations of Bulgarian consumers of organic products are related to the benefits for health and the environment, to the improvement of food quality and to the support of local small farmers, communities and markets.

Decadal surface water quality trends under variable climate, land use, and hydrogeochemical setting in Iowa, USA

Understanding how nitrogen fluxes respond to changes in agriculture and climate is important for improving water quality. In the midwestern United States, expansion of corn cropping for ethanol production led to increasing N application rates in the 2000s during a period of extreme variability of annual precipitation. To examine the effects of these changes, surface water quality was analyzed in 10 major Iowa Rivers. Several decades of concentration and flow data were analyzed with a statistical method that provides internally consistent estimates of the concentration history and reveals flow-normalized trends that are independent of year-to-year streamflow variations. Flow-normalized concentrations of nitrate+nitrite-N decreased from 2000 to 2012 in all basins. To evaluate effects of annual discharge and N loading on these trends, multiple conceptual models were developed and calibrated to flow-weighted annual concentrations. The recent declining concentration trends can be attributed to both very high and very low discharge in the 2000s and to the long (e.g., 8 year) subsurface residence times in some basins. Dilution of N and depletion of stored N occurs in years with high discharge. Reduced N transport and increased N storage occurs in low-discharge years. Central Iowa basins showed the greatest reduction in flow-normalized concentrations, likely because of smaller storage volumes and shorter residence times. Effects of land-use changes on the water quality of major Iowa Rivers may not be noticeable for years or decades in peripheral basins of Iowa, and may be obscured in the central basins where extreme flows strongly affect annual concentration trends.

We keep on truckin': Trends in freight energy use and carbon emissions in 11 IEA countries

International Nuclear Information System (INIS)

Eom, Jiyong; Schipper, Lee; Thompson, Lou

2012-01-01

Based on detailed national and international data on freight transportation, we analyze trends in freight CO 2 emissions in 11 IEA countries from the earliest year of data availability to 2007–2010. The cross-country comparison of the freight transportation sector indicates that per capita CO 2 emissions span a wide range and are mostly determined by local needs without full knowledge or coordination with policies and practices in other countries. Over the last several decades, while many developed countries have experienced decreased coupling between total freight activity (measured in tonne-km) and income, no major indication of decreased coupling between trucking and income was found. Rather, the coupling has been strengthened in many countries due to a continued increase in the share of trucking in total freight activity. The energy intensity of trucking has exhibited very large variation among the countries, and its recent international trends are mixed, providing greater challenges to reduce freight CO 2 emissions. Modal shift toward rail away from truck presents a sizeable opportunity to reduce freight CO 2 emissions, although the potential gain varies widely among the countries. - Highlights: ► We analyze trends in freight CO 2 emissions in 11 IEA countries. ► Many of them experienced decreased coupling between freight and income. ► No major indication of decoupling was found between trucking and income. ► The energy intensity of trucking exhibited very large variation. ► The trends of trucking energy intensity are mixed. ► There is a huge opportunity of reducing emissions by shifting toward rail.

Full Text Available This study presents trends and projected estimates of methane and nitrous oxide emissions from livestock of India vis-à-vis world and developing countries over the period 1961 to 2010 estimated based on IPCC guidelines. World enteric methane emission (EME increased by 54.3% (61.5 to 94.9 ×109 kg annually from the year 1961 to 2010, and the highest annual growth rate (AGR was noted for goat (2.0%, followed by buffalo (1.57% and swine (1.53%. Global EME is projected to increase to 120×109 kg by 2050. The percentage increase in EME by Indian livestock was greater than world livestock (70.6% vs 54.3% between the years 1961 to 2010, and AGR was highest for goat (1.91%, followed by buffalo (1.55%, swine (1.28%, sheep (1.25% and cattle (0.70%. In India, total EME was projected to grow by 18.8×109 kg in 2050. Global methane emission from manure (MEM increased from 6.81 ×109 kg in 1961 to 11.4×109 kg in 2010 (an increase of 67.6%, and is projected to grow to 15×109 kg by 2050. In India, the annual MEM increased from 0.52×109 kg to 1.1×109 kg (with an AGR of 1.57% in this period, which could increase to 1.54×109 kg in 2050. Nitrous oxide emission from manure in India could be 21.4×106 kg in 2050 from 15.3×106 kg in 2010. The AGR of global GHG emissions changed a small extent (only 0.11% from developed countries, but increased drastically (1.23% for developing countries between the periods of 1961 to 2010. Major contributions to world GHG came from cattle (79.3%, swine (9.57% and sheep (7.40%, and for developing countries from cattle (68.3%, buffalo (13.7% and goat (5.4%. The increase of GHG emissions by Indian livestock was less (74% vs 82% over the period of 1961 to 2010 than the developing countries. With this trend, world GHG emissions could reach 3,520×109 kg CO2-eq by 2050 due to animal population growth driven by increased demands for meat and dairy products in the world.

Full Text Available The practice and need to update and form the production and technical base of fishery enterprises have an increasing impact on performance of the fisheries complex and become decisive when considering the prospects for its development on an innovative basis. The paper examines the current state and development trends of the Northern Basin fishing fleet, its production capabilities in developing available bioresources, the need and prospects for renewal. During the research the influence of the main factors determining the formation of the quantitative and structural composition of the fishing fleet has been shown. The most stable and long-term impact is the state of commercial stocks of aquatic biological resources, their variability under the influence of natural factors and anthropogenic load. The second important factor is institutional changes. Initially, since the beginning of the 1990s, this took place due to the transformation of economic relations, and later – to institutional changes in the legislatively approved principles of granting fishing enterprises the right to access water biological resources. The following data have been presented: adaptation of the fleet's production capacities for specialization of fishing activities, ways of modernization and re-equipment, construction of new vessels, acquisition of vessels being in operation in the countries with developed fisheries. These changes had reduced the fleet's production potential raising its qualitative indicators (productivity, depth of processing of raw materials at sea. At the same time, the noted positive trends have been accompanied by some increase in the aging indicators for all groups and types of vessels. The institutional and economic instruments for supporting and stimulating the construction of new fishing vessels have been justified. Nowadays, in the Northern Basin the priority areas of support should be the construction of ships for pelagic fishing and coastal

To evaluate trends in the prevalence of women authors in ophthalmology in recent years. Cohort study. Authors listed in publications of 6 leading ophthalmology journals between January 2002 and December 2014. Using the PubMed search engine, we conducted an observational study of trends in gender distribution of all authors in 6 leading ophthalmology journals between January 2002 and December 2014. In multiauthored articles, the first listed author often is the lead investigator and the last author is the senior author. Therefore, the full names and positions (first, middle, or last) of all authors in every article were collected. A Google-based name identifier was used to assign the gender of authors. Proportion of women authors throughout the study period in all journals, general ophthalmology versus subspecialty journals, and basic science versus clinical research journals. Furthermore, we assessed the proportion of women in different authorship positions (first, middle, and last). A total of 102 254 authors from 23 026 published articles were analyzed. There was a significant rise over time in the percentage of women authors, with a steeper slope for first authors than for last authors (P<0.001), although in 2014, women authors were less than the 50% mark in all categories of authorship. The rise in the percentage of women authors was similar in basic and clinical research, but was steeper for first authorship than for last authorship (P<0.001). In all 3 authorship positions (first, middle, or last), women's contributions consistently were higher in basic research publications. The rise in the percentage of women authors was significantly steeper for general journals than for subspecialty journals (P<0.001). There was no significant rise for last authorship in subspecialty journals. In all 3 authorship positions, the proportion of women was consistently higher in general ophthalmology journals than for subspecialty journals. Despite an overall increase in

Since passage of the Clean Water Act in 1972, Federal, State, and local governments have invested billions of dollars to reduce pollution entering rivers and streams. To understand the return on these investments and to effectively manage and protect the Nation’s water resources in the future, we need to know how and why water quality has been changing over time. As part of the National Water-Quality Assessment Project, of the U.S. Geological Survey’s National Water-Quality Program, data from the U.S. Geological Survey, along with multiple other Federal, State, Tribal, regional, and local agencies, have been used to support the most comprehensive assessment conducted to date of surface-water-quality trends in the United States. This report documents the methods used to determine trends in water quality and ecology because these methods are vital to ensuring the quality of the results. Specific objectives are to document (1) the data compilation and processing steps used to identify river and stream sites throughout the Nation suitable for water-quality, pesticide, and ecology trend analysis, (2) the statistical methods used to determine trends in target parameters, (3) considerations for water-quality, pesticide, and ecology data and streamflow data when modeling trends, (4) sensitivity analyses for selecting data and interpreting trend results with the Weighted Regressions on Time, Discharge, and Season method, and (5) the final trend results at each site. The scope of this study includes trends in water-quality concentrations and loads (nutrient, sediment, major ion, salinity, and carbon), pesticide concentrations and loads, and metrics for aquatic ecology (fish, invertebrates, and algae) for four time periods: (1) 1972–2012, (2) 1982–2012, (3) 1992–2012, and (4) 2002–12. In total, nearly 12,000 trends in concentration, load, and ecology metrics were evaluated in this study; there were 11,893 combinations of sites, parameters, and trend periods. The

Shifting production trends point to more oil from OPEC

International Nuclear Information System (INIS)

Ismail, I.A.H.

1994-01-01

Oil production from the Organization of Petroleum Exporting Countries and non-OPEC regions has undergone four major phases of change in relation to oil price since 1960. Patterns visible in those phases offer an indication of world-wide production trends in the future. These four phases are described. Overall, demand for oil during 1960--93 has increased from around 20 million b/d in 1960 to as high as 65 million b/d in 1993. The consensus among energy analysts and forecasters is that this demand growth will continue. This will encourage OPEC and non OPEC producers to invest in the oil industry to meet future demand growth. However, since the resource base is larger in OPEC than in non-OPEC areas, and since the cost of developing these resources is lower in OPEC than outside OPEC, the future call on OPEC oil to meet growth in demand will undoubtedly be substantiated as production from the non-OPEC region diminishes or at best stagnates. The paper discusses OPEC production trends, non-OPEC production, natural gas liquids, future production scenarios, and future constraints on production

The CGE model of Yunnan’s macro economy was constructed based on the input-output data of Yunnan in 2012, and the development trend of the non-ferrous metals industry (NMI) under the China’s new normal was simulated. In view of this, according to different expected economic growth, and optimized economic structure, the impact on development of Yunnan NMI was simulated. The results show that the NMI growth rate is expected to decline when the economic growth show a downward trend, but the change of the proportion is relatively small. Moreover, the structure in proportion was adjusted to realize the economic structure optimization, while the proportion of NMI in GDP will decline. In contrast, the biggest influence on the NMI is the change of economic structure. From the statistics of last two years, we can see that NMI is growing, and at the same time, its proportion is declining, which is consistent with the results of simulation. But the adjustment of economic structure will take a long time. It is need to improve the proportion of deep-processing industry, extend the industrial chain, enhance the value chain, so as to be made good use of resource advantage.

2011-01-01

Nightlight surveys are commonly used to evaluate status and trends of crocodilian populations, but imperfect detection caused by survey- and location-specific factors makes it difficult to draw population inferences accurately from uncorrected data. We used a two-stage hierarchical model comprising population abundance and detection probability to examine recent abundance trends of American alligators (Alligator mississippiensis) in subareas of Everglades wetlands in Florida using nightlight survey data. During 2001–2008, there were declining trends in abundance of small and/or medium sized animals in a majority of subareas, whereas abundance of large sized animals had either demonstrated an increased or unclear trend. For small and large sized class animals, estimated detection probability declined as water depth increased. Detection probability of small animals was much lower than for larger size classes. The declining trend of smaller alligators may reflect a natural population response to the fluctuating environment of Everglades wetlands under modified hydrology. It may have negative implications for the future of alligator populations in this region, particularly if habitat conditions do not favor recruitment of offspring in the near term. Our study provides a foundation to improve inferences made from nightlight surveys of other crocodilian populations.

Trend Analysis of Worldwide FDI Flows in the Context of Promoting Sustainable Development and National Interest

Directory of Open Access Journals (Sweden)

Alina Georgeta Ailincă

2016-10-01

Full Text Available About FDI there are numerous studies, some of them have mostly theoretical character and others mostly practical. This article aims at capturing and analyzing the most important trends in the short, medium and long term on FDI flows worldwide, thus this study has a rather practical approach. Also, the paper aims to discern how FDI flows may influence the sustainable development and the national interest. The analysis starts from studying the past in the most significant developments of the world economy in terms of inflows of investment attraction, drawing marginally some advantages or disadvantages of joining a political entity with regional vocation (e.g. European Union or a currency area (e.g. E.M.U.. It should also be noted that, beyond the analysis of past trends, the direction towards which worldwide foreign direct investment (FDI should be considered in relationship with the ability to infer certain areas which in future can attract FDI for a sustainable and balanced national economy development, serving to the national interest. Thus, the article aims, through a broad set of indicators, to seize these structural or cyclical advantages of world economies and, to the extent that can be applied to the Romanian economy, to contribute to the restructuring of objectives of macroeconomic policies in order to mobilize the country's potential to attract FDI.

The contributions of risk factor trends and medical care to cardiovascular mortality trends

Ezzati, Majid; Obermeyer, Ziad; Tzoulaki, Ioanna; Mayosi, Bongani M; Elliott, Paul; Leon, David A

2016-01-01

Ischaemic heart disease, stroke, and other cardiovascular diseases (CVDs) are responsible for an estimated 17.5 million annual deaths in the world. If account is taken of population aging, death rates from CVDs are estimated to be steadily decreasing in the world as a whole, and in regions with reliable trend data. The declines in high-income countries and some countries in Latin America have been ongoing for decades with no indication of slowing. In high-income countries, these positive trends have broadly coincided with, and benefited from, declines in smoking and physiological risk factors like blood pressure and serum cholesterol. Improvements in medical care, including effective primary prevention through management of physiological risk factors, better diagnosis and treatment of acute CVDs, and post-hospital care of those with prior CVDs, are also likely to have contributed to declining CVD event and death rates, especially in the past 40 years. However, the measured risk factor and treatment variables neither explain why the decline began when it did, nor much of the similarities and differences in the start time and rate of the decline across countries or between men and women. There have been sharp changes and fluctuations in CVDs in the former communist countries of Europe and the Soviet Union since the fall of communism in the early 1990s, with changes in volume and patterns of alcohol drinking, as a major cause of the rise in Russia and some other former Soviet countries. The challenge of reaching more definitive conclusions concerning the drivers of what constitutes one of the most remarkable international trends in adult mortality in the past half-century in part reflects the paucity of time trend data not only on disease incidence, risk factors, and clinical care, but also on other potential drivers, including infection and associated inflammatory processes throughout the lifecourse.

This study seeks to investigate the variability and presence of trend in the diurnal surface air temperature range (DTR) over North Carolina (NC) for the period 1950-2009. The significance trend test and the magnitude of trends were determined using the non-parametric Mann-Kendall test and the Theil-Sen approach, respectively. Statewide significant trends (p < 0.05) of decreasing DTR were found in all seasons and annually during the analysis period. Highest (lowest) temporal DTR trends of magnitude - 0.19 (- 0.031) °C/decade were found in summer (winter). Potential mechanisms for the presence/absence of trend in DTR have been highlighted. Historical data sets of the three main moisture components (precipitation, total cloud cover (TCC), and soil moisture) and the two major atmospheric circulation modes (North Atlantic Oscillation and Southern Oscillation) were used for correlation analysis. The DTRs were found to be negatively correlated with the precipitation, TCC and soil moisture across the state for all the seasons and annual basis. It appears that the moisture components related better to the DTR than to the atmospheric circulation modes.

Full Text Available This paper presents an overview of major trends in archaeological network research through a bibliometric analysis of the full corpus of publications on the topic between 1965 and 2016. It illustrates we can begin identifying the outlines of a new sub-discipline within archaeology with its distinct traditions, including a diversity of research approaches, dedicated events and preferred publication venues. This sub-discipline is at a similar stage of development as historical network research, and we argue that archaeologists and historians alike interested in establishing network research as a key tool for exploring social change will have a greater chance for success to the extent that we actively collaborate, pool resources, engage in common community activities and publications, and learn from each other’s mistakes.

Nuclear energy is faltering in many places - especially in the USA: should it be written off. The author sees underlying trends that justify a more optimistic view of nuclear energy's future - the continuing tendency for the electricity intensity of economic activity to rise while the total energy intensity falls; a consistently favourable price trend for electricity compared with energy prices generally - a trend that may become more favourable if his judgment that nuclear plants will turn out to be very long-lived is borne out by events; the substitution of electricity-based processes in industry for older processes; and the development of ultra-safe reactors which will remove once and for all the fears of accidents such as the one that occurred at Three Mile Island.

The need for sustainable development has been widely recognized and sustainable development has become a hot topic of various disciplines even though the role of ergonomics in it is seldom reported or considered. This study conducts a systematic survey of research publications in the fields of ergonomics and sustainable development over the past two decades (1992-2011), in order to identify their research trends and convergent areas where ergonomics can play an important role in sustainable development. The results show that 'methods and techniques', 'human characteristics', 'work design and organization', 'health and safety' and 'workplace and equipment design' are the top five frequently researched areas in ergonomics. Ergonomics has an opportunity to contribute its knowledge especially to 'industrial and product design', 'architecture', 'health and safety' and 'HCI' (especially for energy reduction issues) categories of sustainable development. Typical methodologies and general guidance on how to contribute the expertise of ergonomist to sustainable development are also discussed. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

To investigate temporal trends in the incidence, mortality, disability-adjusted life-years (DALYs), and costs of health loss caused by serious road traffic injury. A retrospective review of data from the population-based Victorian State Trauma Registry and the National Coronial Information System on road traffic-related deaths (pre- and in-hospital) and major trauma (Injury Severity Score > 12) during 2007-2015.Main outcomes and measures: Temporal trends in the incidence of road traffic-related major trauma, mortality, DALYs, and costs of health loss, by road user type. There were 8066 hospitalised road traffic major trauma cases and 2588 road traffic fatalities in Victoria over the 9-year study period. There was no change in the incidence of hospitalised major trauma for motor vehicle occupants (incidence rate ratio [IRR] per year, 1.00; 95% CI, 0.99-1.01; P = 0.70), motorcyclists (IRR, 0.99; 95% CI, 0.97-1.01; P = 0.45) or pedestrians (IRR, 1.00; 95% CI, 0.97-1.02; P = 0.73), but the incidence for pedal cyclists increased 8% per year (IRR, 1.08; 95% CI; 1.05-1.10; P road traffic injuries exceeded $14 billion during 2007-2015, although the cost per patient declined for all road user groups. As serious injury rates have not declined, current road safety targets will be difficult to meet. Greater attention to preventing serious injury is needed, as is further investment in road safety, particularly for pedal cyclists.

Progress in reorganization of international oil industry and moves of majors

Energy Technology Data Exchange (ETDEWEB)

(Institute of Energy Economics, Tokyo (Japan))

1988-10-15

Of oil majors, Texaco, Chevron and Mobil have become depressed because of the sharp decrease in oil abundance due to the OPEC members' nationalization policy of resources in the first half of 1970's, whereas Exxon and Shell, who have made steady efforts in investment for exploration and development, have grown. BP has made a wide stride by acquisitions. Business acquisitions and mergers are increasing again in oil industries of Europe and U.S. with the dull oil price as the background. A particular feature of this trend is active involvement of western firms in North Sea oil. Oil producing countries are actively penetrating in downstream markets of consuming countries to establish stable selling routes. Whereas two directions are possible for changes in the international petroleum industry, that is, either coordinated action of producing countries and majors or increased competition among them, the age of co-existence and co-prosperity is most probable. 1 figure.

Automating Trend Analysis for Spacecraft Constellations

Spacecraft trend analysis is a vital mission operations function performed by satellite controllers and engineers, who perform detailed analyses of engineering telemetry data to diagnose subsystem faults and to detect trends that may potentially lead to degraded subsystem performance or failure in the future. It is this latter function that is of greatest importance, for careful trending can often predict or detect events that may lead to a spacecraft's entry into safe-hold. Early prediction and detection of such events could result in the avoidance of, or rapid return to service from, spacecraft safing, which not only results in reduced recovery costs but also in a higher overall level of service for the satellite system. Contemporary spacecraft trending activities are manually intensive and are primarily performed diagnostically after a fault occurs, rather than proactively to predict its occurrence. They also tend to rely on information systems and software that are oudated when compared to current technologies. When coupled with the fact that flight operations teams often have limited resources, proactive trending opportunities are limited, and detailed trend analysis is often reserved for critical responses to safe holds or other on-orbit events such as maneuvers. While the contemporary trend analysis approach has sufficed for current single-spacecraft operations, it will be unfeasible for NASA's planned and proposed space science constellations. Missions such as the Dynamics, Reconnection and Configuration Observatory (DRACO), for example, are planning to launch as many as 100 'nanospacecraft' to form a homogenous constellation. A simple extrapolation of resources and manpower based on single-spacecraft operations suggests that trending for such a large spacecraft fleet will be unmanageable, unwieldy, and cost-prohibitive. It is therefore imperative that an approach to automating the spacecraft trend analysis function be studied, developed, and applied to

Road traffic accidents and their related deaths have become a major concern, particularly in developing countries. Iran has adopted a series of policies and interventions to control the high number of accidents occurring over the past few years. In this study we used a time series model to understand the trend of accidents, and ascertain the viability of applying ARIMA models on data from Taybad city. This study is a cross-sectional study. We used data from accidents occurring in Taybad between 2007 and 2011. We obtained the data from the Ministry of Health (MOH) and used the time series method with a time lag of one month. After plotting the trend, non-stationary data in mean and variance were removed using Box-Cox transformation and a differencing method respectively. The ACF and PACF plots were used to control the stationary situation. The traffic accidents in our study had an increasing trend over the five years of study. Based on ACF and PACF plots gained after applying Box-Cox transformation and differencing, data did not fit to a time series model. Therefore, neither ARIMA model nor seasonality were observed. Traffic accidents in Taybad have an upward trend. In addition, we expected either the AR model, MA model or ARIMA model to have a seasonal trend, yet this was not observed in this analysis. Several reasons may have contributed to this situation, such as uncertainty of the quality of data, weather changes, and behavioural factors that are not taken into account by time series analysis.

As many as half of all patients with major traumatic injuries do not receive the recommended care, with variance in preventable mortality reported across the globe. This variance highlights the need for a comprehensive process for monitoring and reviewing patient care, central to which is a consistent peer-review process that includes trauma system safety and human factors. There is no published, evidence-informed standardised tool that considers these factors for use in adult or paediatric trauma case peer-review. The aim of this research was to develop and validate a trauma case review tool to facilitate clinical review of paediatric trauma patient care in extracting information to facilitate monitoring, inform change and enable loop closure. Development of the trauma case review tool was multi-faceted, beginning with a review of the trauma audit tool literature. Data were extracted from the literature to inform iterative tool development using a consensus approach. Inter-rater agreement was assessed for both the pilot and finalised versions of the tool. The final trauma case review tool contained ten sections, including patient factors (such as pre-existing conditions), presenting problem, a timeline of events, factors contributing to the care delivery problem (including equipment, work environment, staff action, organizational factors), positive aspects of care and the outcome of panel discussion. After refinement, the inter-rater reliability of the human factors and outcome components of the tool improved with an average 86% agreement between raters. This research developed an evidence-informed tool for use in paediatric trauma case review that considers both system safety and human factors to facilitate clinical review of trauma patient care. This tool can be used to identify opportunities for improvement in trauma care and guide quality assurance activities. Validation is required in the adult population.

Is Google Trends a reliable tool for digital epidemiology? Insights from different clinical settings.

Science.gov (United States)

Cervellin, Gianfranco; Comelli, Ivan; Lippi, Giuseppe

2017-09-01

Internet-derived information has been recently recognized as a valuable tool for epidemiological investigation. Google Trends, a Google Inc. portal, generates data on geographical and temporal patterns according to specified keywords. The aim of this study was to compare the reliability of Google Trends in different clinical settings, for both common diseases with lower media coverage, and for less common diseases attracting major media coverage. We carried out a search in Google Trends using the keywords "renal colic", "epistaxis", and "mushroom poisoning", selected on the basis of available and reliable epidemiological data. Besides this search, we carried out a second search for three clinical conditions (i.e., "meningitis", "Legionella Pneumophila pneumonia", and "Ebola fever"), which recently received major focus by the Italian media. In our analysis, no correlation was found between data captured from Google Trends and epidemiology of renal colics, epistaxis and mushroom poisoning. Only when searching for the term "mushroom" alone the Google Trends search generated a seasonal pattern which almost overlaps with the epidemiological profile, but this was probably mostly due to searches for harvesting and cooking rather than to for poisoning. The Google Trends data also failed to reflect the geographical and temporary patterns of disease for meningitis, Legionella Pneumophila pneumonia and Ebola fever. The results of our study confirm that Google Trends has modest reliability for defining the epidemiology of relatively common diseases with minor media coverage, or relatively rare diseases with higher audience. Overall, Google Trends seems to be more influenced by the media clamor than by true epidemiological burden. Copyright © 2017 Ministry of Health, Saudi Arabia. Published by Elsevier Ltd.

Trends in renewable energy strategy development and the role of CDM in Bangladesh

International Nuclear Information System (INIS)

Noim Uddin, Sk; Taplin, Ros

2009-01-01

This article analyses and discusses trends in renewable energy strategy development in Bangladesh and the prospective role of the clean development mechanism (CDM) under the Kyoto Protocol. Use of renewables for electricity generation results in less greenhouse gas emissions compared with fossil fuel energy systems and often offers additional synergistic benefits. Despite the large potential for development of renewable energy sources in Bangladesh, currently their contribution to electricity generation remains insignificant. Existing policies and programs on renewable energy in Bangladesh are reviewed in relation to the specific requirements needed for CDM. A number of barriers are identified that impede the implementation of the CDM mechanism. Overall, it is recommended that more appropriate energy strategies, including a new national renewable energy strategy, need to be formulated and implemented and more suitable institutional settings need to be provided to promote energy sustainability for Bangladesh. Also, the suggestion is made that incorporation of objectives for CDM promotion in the new national renewable energy strategy to tie in with Bangladesh's CDM strategy should assist in advancement of renewables

fractured and sealed by overlying argillaceous and non-fractured units. The best outcrop analogs for Twin Creek reservoirs are found at Devils Slide and near the town of Peoa, Utah, where fractures in dense, homogeneous non-porous limestone beds are in contact with the basal siltstone units (containing sealed fractures) of the overlying units. The shallow marine, Mississippian Leadville Limestone is a major oil and gas reservoir in the Paradox Basin of Utah and Colorado. Hydrocarbons are produced from basement-involved, northwest-trending structural traps with closure on both anticlines and faults. Excellent outcrops of Leadville-equivalent rocks are found along the south flank of the Uinta Mountains, Utah. For example, like the Leadville, the Mississippian Madison Limestone contains zones of solution breccia, fractures, and facies variations. When combined with subsurface geological and production data, these outcrop analogs can improve (1) development drilling and production strategies such as horizontal drilling, (2) reservoir-simulation models, (3) reserve calculations, and (4) design and implementation of secondary/tertiary oil recovery programs and other best practices used in the oil fields of Utah and vicinity. In the southern Green River Formation play of the Uinta Basin, optimal drilling, development, and production practices consist of: (1) owning drilling rigs and frac holding tanks; (2) perforating sandstone beds with more than 8 percent neutron porosity and stimulate with separate fracture treatments; (3) placing completed wells on primary production using artificial lift; (4) converting wells relatively soon to secondary waterflooding maintaining reservoir pressure above the bubble point to maximize oil recovery; (5) developing waterflood units using an alternating injector--producer pattern on 40-acre (16-ha) spacing; and (6) recompleting producing wells by perforating all beds that are productive in the waterflood unit.

Much of the literature on trends and factors affecting biopharmaceutical innovation has focused overwhelmingly on the development and approval of never-before approved drugs and biologics. Little attention has been paid to new uses for already-approved compounds, which can be an important form of innovation. This paper aimed to determine and analyze recent trends in the number and type of new or modified US indication approvals for drugs and biologics. We also examine regulatory approval-phase times for new-use efficacy supplements and compare them to approval-phase times for original-use approvals over the same period. We developed a data set of efficacy supplements approved by the US Food and Drug Administration (FDA) from 1998 to 2011 that includes information on the type, approval-phase time (time from submission to the FDA of an application for marketing approval to approval of the application), and FDA therapeutic-significance rating for the approved application, which we obtained from an FDA Web site. This data set was merged with a Tufts Center for the Study of Drug Development (CSDD) data set of US new drug and biologics approvals. We developed descriptive statistics on trends in the number and type of new-use efficacy supplements, on US regulatory approval-phase times for the supplements, and on original new drug and biologics approvals over the study period and for the time from original- to new-use approval. The total number of new-use efficacy-supplement approvals did not exhibit a marked trend, but the number of new pediatric-indication approvals increased substantially. Approval-phase times for new-use supplements varied by therapeutic class and FDA therapeutic-significance rating. Mean approval-phase times were highest for central nervous system compounds (13.8 months) and lowest for antineoplastics (8.9 months). The mean time from original to supplement approval was substantially longer for new pediatric indications than for other new uses. Mean

Evolution of Project Management in Integration Development Trends of Today’s Russia

Full Text Available Today’s development trends are affected by many external and internal factors, stepping up globalization processes, faster innovation cycles, negative effects of various bans, import and export sanctions slapped on some categories of goods, technologies, capital, etc. Tit-for-tat responses of the economic systems seek sustainable development of countries taking part in the integration processes. A radical-yet-constructive strategy that deepens integration can tackle the problem. Its focus is determined by the need to upgrade the economies of the former Soviet Union; while a mutual interest in the rollout of the synergistic integration potential channels common efforts on transcontinental megaprojects. A new type of integration projects creates comprehensive methods of project management. They feature the need for information transparency and controlled alignment of innovation, investment, construction and resource capacities of member countries. With streamlined resource flows, the Eurasian transit will help facilitate and cut costs of commodity exchange among countries, provided they take synchronized efforts in not just technical and technological, but also organizational, economic, legal and IT innovations.

Agricultural ecological compensation has drawn an increasingly broad range of interest since early 1990s. In recent years, the volume of the literature grows rapidly. As a result, a systematic review of the diverse research field and its current trends becomes essential. This paper surveys the literature of agricultural ecological compensation between 1990 and 2016. Specifically, by employing CiteSpace information visualization software, we firstly identified the research hotspots and evolution path and then illustrated the frontier and developing trend of the domain in core and broader perspectives. It is found that the focus of the academic community has always been researches on the theoretical policy and application of the payment for agro-ecosystem services, agricultural ecological compensation based on contingent valuation method, and ecological compensation of farmland landscape and organic food production as well as willingness to accept/pay for land use and ecological protection. Meanwhile, we also found that, in recent years, qualitative research has received more and more attention in the field of agricultural ecological compensation, since global warming, agricultural carbon emissions, and other emerging environmental issues have aroused widespread concern of the people around the world. Moreover, we believed that more and more scholars will employ case study methodology to analyze agricultural ecological compensation in specific systems, regions, or circumstances in the future.

Global Survey on Future Trends in Human Spaceflight: the Implications for Space Tourism

2002-01-01

With the much-publicized first ever space tourist flight, of Dennis Tito, and the announcement of the second space tourist flight to take place in April 2002, it is clear that an alternative motivation for human spaceflight has emerged. Human spaceflight is no longer only about meeting the priorities of national governments and space agencies, but is also about the tangible possibility of ordinary people seeing the Earth from a previously exclusive vantage point. It is imperative that major space players look beyond the existing human spaceflight rationale to identify some of the major driving forces behind space tourism, including the evolving market potential and developments in enabling technologies. In order to determine the influence of these forces on the future of commercial human spaceflight, the responses of a Futuraspace survey on future trends in human spaceflight are analyzed and presented. The motivation of this study is to identify sought-after space destinations, explore the expected trends in enabling technologies, and understand the future role of emerging space players. The survey will reflect the opinions of respondents from around the world including North America, Europe (including Russia) and Asia. The profiles of targeted respondents from space industry, government and academia are high-level executives/managers, senior researchers, as well as former and current astronauts. The survey instrument is a questionnaire which is validated by a pilot study. The sampling method is non-probabilistic, targeting as many space experts as possible who fit our intended respondent profile. Descriptive and comparative statistical analysis methods are implemented to investigate both global and regional perceptions of future commercial trends in human spaceflight. This study is not intended to be a formal market study of the potential viability of the space tourism market. Instead, the focus is on the future trends of human spaceflight, by drawing on the

We developed a practical influenza forecast model based on real-time, geographically focused, and easy to access data, designed to provide individual medical centers with advanced warning of the expected number of influenza cases, thus allowing for sufficient time to implement interventions. Secondly, we evaluated the effects of incorporating a real-time influenza surveillance system, Google Flu Trends, and meteorological and temporal information on forecast accuracy. Forecast models designed to predict one week in advance were developed from weekly counts of confirmed influenza cases over seven seasons (2004-2011) divided into seven training and out-of-sample verification sets. Forecasting procedures using classical Box-Jenkins, generalized linear models (GLM), and generalized linear autoregressive moving average (GARMA) methods were employed to develop the final model and assess the relative contribution of external variables such as, Google Flu Trends, meteorological data, and temporal information. A GARMA(3,0) forecast model with Negative Binomial distribution integrating Google Flu Trends information provided the most accurate influenza case predictions. The model, on the average, predicts weekly influenza cases during 7 out-of-sample outbreaks within 7 cases for 83% of estimates. Google Flu Trend data was the only source of external information to provide statistically significant forecast improvements over the base model in four of the seven out-of-sample verification sets. Overall, the p-value of adding this external information to the model is 0.0005. The other exogenous variables did not yield a statistically significant improvement in any of the verification sets. Integer-valued autoregression of influenza cases provides a strong base forecast model, which is enhanced by the addition of Google Flu Trends confirming the predictive capabilities of search query based syndromic surveillance. This accessible and flexible forecast model can be used by

Trends in sustainable landfilling in Malaysia, a developing country.

Fauziah, S H; Agamuthu, P

2012-07-01

In Malaysia, landfills are being filled up rapidly due to the current daily generation of approximately 30,000 tonnes of municipal solid waste. This situation creates the crucial need for improved landfilling practices, as sustainable landfilling technology is yet to be achieved here. The objective of this paper is to identify and evaluate the development and trends in landfilling practices in Malaysia. In 1970, the disposal sites in Malaysia were small and prevailing waste disposal practices was mere open-dumping. This network of relatively small dumps, typically located close to population centres, was considered acceptable for a relatively low population of 10 million in Malaysia. In the 1980s, a national programme was developed to manage municipal and industrial wastes more systematically and to reduce adverse environmental impacts. The early 1990s saw the privatization of waste management in many parts of Malaysia, and the establishment of the first sanitary landfills for MSW and an engineered landfill (called 'secure landfill' in Malaysia) for hazardous waste. A public uproar in 2007 due to contamination of a drinking water source from improper landfilling practices led to some significant changes in the government's policy regarding the country's waste management strategy. Parliament passed the Solid Waste and Public Cleansing Management (SWPCM) Act 2007 in August 2007. Even though the Act is yet to be implemented, the government has taken big steps to improve waste management system further. The future of the waste management in Malaysia seems somewhat brighter with a clear waste management policy in place. There is now a foundation upon which to build a sound and sustainble waste management and disposal system in Malaysia.

2018-02-01

With the growth and popularity of the utilization of artificial intelligence (AI) in several fields and industries, studies in the field of medicine have begun to implement its capabilities in handling and analyzing data to telemedicine. With the challenges in the implementation of telemedicine, there has been a need to expand its capabilities and improve procedures to be specialized to solve specific problems. The versatility and flexibility of both AI and telemedicine gave the endless possibilities for development and these can be seen in the literature reviewed in this paper. The trends in the development of the utilization of this technology can be classified in to four: patient monitoring, healthcare information technology, intelligent assistance diagnosis, and information analysis collaboration. Each trend will be discussed and presented with examples of recent literature and the problems they aim to address. Related references will also be tabulated and categorized to see the future and potential of this current trend in telemedicine.

Full Text Available The objective of this study was to determine the changing trend of leptospirosis over time in Thailand using two prospective hospital-based studies conducted amongst adult patients with acute undifferentiated fever (AUFI admitted to Maharat Nakhon Ratchasima Hospital, Nakhon Ratchasima Province, Thailand between July 2001 to December 2002 and between July 2011 to December 2012. During the first period, leptospirosis (98 patients, 40% and scrub typhus (59 patients, 24.1% were the two major causes of AUFI. In the second period, scrub typhus (137 patients, 28.3% was found to be more common than leptospirosis (61 patients, 12.7%. Amongst patients with leptospirosis, the proportion of male patients and the median age were similar. Leptospira interrogans serogroup Autumnalis was the major infecting serogroup in both study periods. The case fatality rate of leptospirosis was significantly higher in 2011–2012 as compared with the case fatality rate in 2001–2002 (19.7% vs. 6.3%, p < 0.001. In summary, we found that number of leptospirosis cases had decreased over time. This trend is similar to reportable data for leptospirosis complied from passive surveillance by the Ministry of Public Health, Thailand. However, the case fatality rate of severe leptospirosis has increased. Severe lung hemorrhage associated with leptospirosis remained the major cause of death.

The objective of the study was to examine mortality trends and causes of death among professional athletes from the four major sports in North America who died during their playing careers. 205 deceased athletes who were registered as active when they died from the National Basketball Association (NBA), National Football League (NFL), National Hockey League (NHL), and Major League Baseball (MLB) were examined. Results were compared with the Canadian and U.S. general population. The leading causes of death in players reflected the leading causes of death in the Canadian and U.S. general population (i.e., car accidents). Descriptively, NFL and NBA players had a higher likelihood of dying in a car accident (OR 1.75, 95% CI: 0.91-3.36) compared with NHL and MLB players. In addition, NFL and NBA players had a significantly higher likelihood of dying from a cardiac-related illness (OR 4.44, 95% CI: 1.59-12.43). Mortality trends were disproportionate to team size. Overall, death in active athletes is low. Out of 53 400 athletes who have historically played in the four leagues, only 205 died while active (0.38%). Future examinations into the trends and causes of mortality in elite athlete populations will create a better understanding of health-related risks in elite sport. © 2015 John Wiley & Sons A/S.

Google Flu Trends was developed to estimate influenza activity in many countries; however there is currently no Google Flu Trends or other Internet search data used for influenza surveillance in China. Influenza surveillance data from 2008 through 2011 were obtained from provincial CDC influenza-like illness and virological surveillance systems of Guangdong, a province in south China. Internet search data were downloaded from the website of Google Trends. Pearson's correlation coefficients with 95% confidence intervals (95% CI) were calculated to compare surveillance data and internet search trends. The correlation between CDC ILI surveillance and CDC virus surveillance was 0.56 (95% CI: 0.43, 0.66). The strongest correlation was between the Google Trends term of Fever and ILI surveillance with a correlation coefficient of 0.73 (95% CI: 0.66, 0.79). When compared with influenza virological surveillance, the Google Trends term of Influenza A had the strongest correlation with a correlation coefficient of 0.64 (95% CI: 0.43, 0.79) in the 2009 H1N1 influenza pandemic period. This study shows that Google Trends in Chinese can be used as a complementary source of data for influenza surveillance in south China. More research in the future should develop new models using search trends in Chinese language to estimate local disease activity and detect early signals of outbreaks.

-treatment processes, and effective regulations. Phosphorus data for most of the study stations could not be analyzed because of the data limitations for trend tests. The only station with a significant negative trend in total phosphorus concentration is the Clinton River at Mount Clemens. However, scatter-plot analyses of phosphorus data indicate decreasing concentrations with time for most of the study stations. Positive trends in concentration of nitrogen compounds were detected at the Kalamazoo River near Saugatuck and Muskegon River near Bridgeton. Positive trends in both fecal coliform and total fecal coliform were detected at the Tahquamenon River near Paradise. Various different point and nonpoint sources could produce such positive trends, but most commonly the increase in concentrations of nitrogen compounds and fecal coliform bacteria are associated with agricultural practices and sewage-plant discharges. The constituent with the most numerous and geographically widespread significant trend is pH. The pH levels increased at six out of nine stations on all the major rivers in Michigan, with no negative trend at any station. The cause of pH increase is difficult to determine, as it could be related to a combination of anthropogenic activities and natural processes occurring simultaneously in the environment. Trends in concentration of major ions, such as calcium, sodium, magnesium, sulfate, fluoride, chloride, and potassium, were detected at eight out of nine stations. A negative trend was detected only in sulfate and fluoride concentrations; a positive trend was detected only in calcium concentration. The major ions with the most widespread significant trends are sodium and chloride; three positive and two negative trends were detected for sodium, and three negative and two positive trends were detected for chloride. The negative trends in chloride concentrations outnumbered the positive trends. This result indicates a slight improvement in surface-water quality because

Offshore Blowouts, Causes and Trends

The main objective of this doctoral thesis was to establish an improved design basis for offshore installations with respect to blowout risk analyses. The following sub objectives are defined: (1) Establish an offshore blowout database suitable for risk analyses, (2) Compare the blowout risk related to loss of lives with the total offshore risk and risk in other industries, (3) Analyse blowouts with respect to parameters that are important to describe and quantify blowout risk that has been experienced to be able to answer several questions such as under what operations have blowouts occurred, direct causes, frequency of occurrence etc., (4) Analyse blowouts with respect to trends. The research strategy applied includes elements from both survey strategy and case study strategy. The data are systematized in the form of a new database developed from the MARINTEK database. Most blowouts in the analysed period occurred during drilling operations. Shallow gas blowouts were more frequent than deep blowouts and workover blowouts occurred more often than deep development drilling blowouts. Relatively few blowouts occurred during completion, wireline and normal production activities. No significant trend in blowout occurrences as a function of time could be observed, except for completion blowouts that showed a significantly decreasing trend. But there were trends regarding some important parameters for risk analyses, e.g. the ignition probability has decreased and diverter systems have improved. Only 3.5% of the fatalities occurred because of blowouts. 106 refs., 51 figs., 55 tabs.

Natural fractures in seven wells from the Middle Permian Lucaogou Formation in the Junggar Basin were evaluated in light of regional structural evolution, tight reservoir geochemistry (including TOC and mineral composition), carbon and oxygen isotopes of calcite-filled fractures, and acoustic emission (AE). Factors controlling the development of natural fractures were analyzed using qualitative and/or semi-quantitative techniques, with results showing that tectonic factors are the primary control on fracture development in the Middle Permian Lucaogou Formation of the Junggar Basin. Analyses of calcite, dolomite, and TOC show positive correlations with the number of fractures, while deltaic lithofacies appear to be the most favorable for fracture development. Mineral content was found to be a major control on tectonic fracture development, while TOC content and sedimentary facies mainly control bedding fractures. Carbon and oxygen isotopes vary greatly in calcite-filled fractures (δ13C ranges from 0.87‰ to 7.98‰, while δ18O ranges from -12.63‰ to -5.65‰), indicating that fracture development increases with intensified tectonic activity or enhanced diagenetic alteration. By analyzing the cross-cutting relationships of fractures in core, as well as four Kaiser Effect points in the acoustic emission curve, we observed four stages of tectonic fracture development. First-stage fractures are extensional, and were generated in the late Triassic, with calcite fracture fills formed between 36.51 °C and 56.89 °C. Second-stage fractures are shear fractures caused by extrusion stress from the southwest to the northeast, generated by the rapid uplift of the Tianshan in the Middle and Late Jurassic; calcite fracture fills formed between 62.91 °C and 69.88 °C. Third-stage fractures are NNW-trending shear fractures that resulted from north-south extrusion and thrusting in a foreland depression along the front of the Early Cretaceous Bogda Mountains.

It is concluded that the chemical industry is one of the EU’s most successful spheres, boasting €527 billion in sales in 2013, making it the second-largest global manufacture. Methodology. To explain the competitiveness of the EU chemical branch in the global market, it is proposed the constant-market share methodology to chemical exports coupled with econometric analysis. Results. The constant market share (CMS approach to assessing competitiveness, developed in the 1970 s for analysis of trade, is based on the principle that changes in the geographic and product structures of exports will affect a country’s export growth relative to that of the world, and that is way its global export market share. There were analyzed the EU biggest exporters (Germany, France, Italy, UK, Spain, Netherlands, Belgium, Poland, the USA, Japan; China, India, Saudi Arabia, Brazil. Practical implication. The analysis presents the results of competitiveness assessment in a different way, showing the average annual growth rate of EU and world chemical exports in the top section and then decomposing the gap between the two into that thanks to growth dynamics (structure effect and competitive effect. It is defined a lot of factors that are important to industrial competitiveness. On the cost side, in many industries labor is a large enough share of overall production costs that international differences in salaries can have a large bearing on competitiveness. Costs are also affected by a variety of government policies. It is also defined that innovation is one of the most important factors, which opens up new opportunities both in terms of new products and more efficient processes for manufacturing existing products.

2014-11-01

Full Text Available This study analyzes and evaluates the status and long-term trend of regional economic sustainability in eastern Anhui Province, China. Based on the triangle model and the definition of economic sustainable development, this study evaluates the interrelationship among regional economic development, resource-energy consumption, environmental pollution, and ecological performance. The sustainable and comprehensive utilization situation in the study region from 1975–2012 is examined. The results show that in 2012, the comprehensive development in the study region had a general status in terms of sustainability. The sustainable development trend of the seven administrative subunits inside the region had a weak and general status in terms of sustainability, while the status of sustainability in the southeastern part of the region was better than that in the northwest. During the period from 1975–1998, the study region’s comprehensive development presented a trend of general sustainability. In the period from 1998–2012, the region experienced a trend of very strong sustainability in its development. These statuses and trends have a certain relationship with the study region’s strong economic development and environmental protection over the past 37 years. The triangle method, as an intuitive platform for illustrating sustainability status and trends in economic development, seems to hold promise as an analytical management tool given its simplicity, ease of use, and flexibility.

1973-01-01

The author has identified the following significant results. Major structural trends have been compiled on five separate maps, at a scale of 1:1,000,000, of Utah and Nevada from ERTS-1 imagery. An arbitrary length of ten kilometers has been chosen as a minimum length of the trends. The selection is based upon: (1) obvious displacement of structures; (2) continuity or persistence of trends across structures; (3) line-up of outcrop patterns, drainage, erosional features or vegetation; and (4) near-linear trends. Several recognizable trend directions have noted, viz., N 10-15 deg W, N 35 deg W, N 80 deg W, N 30 deg E, and E-W. More than 1500 structural trends have been identified, some of which are mineralized and extend into pediment or shallow alluvial cover. Those fracture trends that exhibit mineralization in exposed bedrock will be assayed for mercury content with a soil-gas analyzer and similar collection will be done over alluvial posture blankets by the same technique with the hope of discovering blind mineralized zones that are not exposed on the surface.

This paper provides a brief overview of radiation detector history, a summary of the present state of the art, and some speculation on future developments in this field. Trends in the development of radiation detectors over the years are analyzed. Rapid progress in detection technology was experienced between WWII and the 1970s. Since then, fewer dramatic improvements have been seen. The authors speculate about the reasons for this trend and where the technology might take us in the next 20 years. Requirements for radiation detection equipment have changed drastically since 9/11; this demand is likely to accelerate detector development in the near future

Full Text Available In the beginning of the 20th century the food consumption levels were much lower than later in the century, when food production increased as well. The selection of foodstuffs became wider and we can observe the modernisation of nutrition principles too, which both had a positive impact on consumption. The variety of food was also affected by the increasing life expectancy. The emergence of more modern ways in food consumption is halted not only by the traditions but by the fact that healthier foods are more expensive than fat or cereal prices. There is a significant correlation between the income levels and the quality of consumed food, as it can be observed that in different regions in Hungary. My aim was also to investigate the change in consumer behaviour in parallel with the increase of income levels; to see which sort of foods are preferred by the wealthier, and which are preferred by the ones with less income. It is also important to analyse the economic and social indicators on regional and other spatial levels and to compare them with food consumption. The annual net income per capita is usually higher in more developed regions than in the less developed ones. Therefore, the expenditure spent on better quality and more expensive food products is also higher. Similarly, in the case of the population there are differences in consumer habits according to purchasing power. For instance, for people with higher income one of the most important factors is to buy healthy and high quality food, but for the ones with lower income it can be a struggle only to find food in sufficient quantities, and quality cannot be as much of an issue. In the consumer basket, foodstuff accounts for approximately one-third of the overall expenditure. In this study I analysed the annual expenditure of Hungary’s population on foodstuffs and the annual quantity of food consumed by households per capita on a regional level between 2010 and 2013.
