    Full Text Available The importance of contemporary design competitions has been increasingly recognized in fast-growing China in the course of World Trade Organization (WTO integration and globalization. However, scientific and systematic analysis is rare on how international design competitions are introduced, and how they interact and transplant in the Chinese context. The well-known Chinese-Western culture gap and complicated social and political background make this topic more challenging. Herein, the authors focus on how the international design competitions were “translated” into both international and local perspectives with a compara­tive analysis on development of international design competitions between the Chinese and the Finnish model. To fully exemplify the design-completion procedure and the different roles of Chinese stakeholders and their perspectives on design competitions, the authors study the Baietan case, which was chosen due to its specific relationship with the city’s strategic plan, its representativeness in using international design competitions in connection to large-scale urban projects in China and its public access to the relevant documentation. The preliminary findings suggest that Chinese-style design competitions, acting as ‘designed trading zones’, with less-defined competition rules compared to the Finnish model, may foster the settings of local transformation in adopting international urban planning and design knowledge. However, an integrated approach is required to address subsequent implementation.

    Pattern design and, technology play a very important role in the garment industry. In order to improve the level of pattern making and design of the garment industry, a survey was conducted to investigate the industrial needs in pattern design and technology in mainland China. The data were collected from the employers and employees from the garment industry and students in the major of fashion and clothing studies. It indicated that there was a gap between the employer and employee, especially the requirements of the industrial needs and the course contents covered by the tertiary schools. The employers expected to recruit more experienced pattern designers, at the same time, they were not reluctant to hire fresh graduates and spent more resources on the training of employees. The students knew little about their employment situation of the garment industry, spent too little time on the course study and learned too little practical skills in pattern design. They could not make use of the knowledge which prevented them from being employed by the garment industry. Efforts should be taken by both the tertiary schools and the garment industry. The students should be aspirated towards the profession of pattern cutters and the syllabuses of pattern making should be more practical and industrial orientated. The solution might benefit the garment industry a lot in a long run.

  4. Opportunities and barriers for implementing CO2 capture ready designs: A case study of stakeholder perceptions in Guangdong, China

    International Nuclear Information System (INIS)

    China has been building at least 50 gigawatt (GW) of new coal-fired power plants every year since 2004. In the absence of CO2 capture ready (CCR) designs, a large fraction of new coal power plants built in the next decade could face ‘carbon lock-in’. Building on the existing engineering and economic literature on CO2 capture ready, the aim of this study is to understand the opportunities and challenges in implementing CCR in China. In early 2010, opinion-leaders perceptions towards implementing CCR in Guangdong with two empirical phases are presented: an online consultation of 31 respondents (out of a sample of 82), three face-to-face focus group discussions including 16 officials from five power plants and two oil companies in the Guangdong province. A majority of respondents in the online survey were engineers. The survey results are compared with an earlier study of stakeholders’ views on demonstrating CCS in China, conducted in April 2009 as part of the EU–UK–China Near Zero Emissions Coal initiative (NZEC) project. - Highlights: ► Without national support, interests from project management and local government help deploy CCR. ► Space on-site and access to storage sites are two essential criteria. ► It is also necessary to investigate the local plant design conventions and regulations. ► Five potential barriers to implementing CCR are identified. ► Four potential drivers may accelerate the implementation of CCR.

    Full Text Available Abstract Background "Doing the month", or "sitting month", is a traditional practice for postpartum women in China and other Asian countries, which includes some taboos against well-accepted healthy diet and lifestyles in general population. Previous studies have shown this practice may be associated with higher prevalence of postpartum problems. The current multicenter randomized controlled trial (RCT aims to evaluate outcomes of diet and lifestyle interventions in Chinese postpartum women. Methods/Design The current multicenter RCT will be conducted in three representative areas in China, Shandong province, Hubei province and Guangdong province, which locate in northern, central and southern parts of China, respectively. Women who attend routine pregnancy diagnosis in hospitals or maternal healthcare centers will be invited to take part in this study. At least 800 women who meet our eligibility criteria will be recruited and randomly assigned to the intervention group (n > = 400 and the control group (n > = 400. A three-dimension comprehensive intervention strategy, which incorporates intervention measures simultaneously to individual postpartum woman, their family members and community environment, will be utilized to maximize the effectiveness of intervention. Regular visiting and follow-up will be done in both group; nutrition and health-related measurements will be assessed both before and after the intervention. Discussion To our knowledge, this current study is the first and largest multicenter RCT which focus on the effectiveness of diet and lifestyle intervention on reducing the incidence rate of postpartum diseases and improving health status in postpartum women. We hypothesize that the intervention will reduce the incidence rates of postpartum diseases and improve nutrition and health status due to a balanced diet and reasonable lifestyle in comparison with the control condition. If so, the results of our study will provide

    Over the past 50 years, with the improvement of relationship between India and China, the scope of India studies in China's IR research has been broadened and the new areas of studies are being explored. The research agenda of India studies has already extended to the areas like economy, society, culture, security, national strategy and their impact on both bilateral and international relations. In this situation, the focuses of India studies in China's IR research can be mainly identified as follows: reviews on India's social, political and economic systems; analysis on the national strategy and foreign policy; Sino-Indian relations; India's relations with some international organizations. However, even though many fresh progresses have been made in India studies, the India studies in China's IR research still lag far behind the study of other important countries like the U.S., UK, Russia and Japan, and more problems and challenges will face in the coming future. The paper believes that a fuller understanding of India probably will not make China and India close friends, but it definitely will help to prevent them from becoming fierce enemies.

  16. China: Ingestion study

    International Nuclear Information System (INIS)

    Diet samples in China were collected according to the sampling strategy devised for the 'First Total Diet Study in China' in 1990 by the Institute of Nutrition and Food Hygiene, Chinese Academy of Preventive Medicine. Based on geographic location, dietary habits and cooking style, the whole of China was divided into 4 regions and from each region one province was selected for the survey. In each of these provinces, 3 survey points (one town and two countryside) were identified, from where 30 families were randomly chosen. The diet composition and the consumption of various food items were recorded by means of weight record for three successive days. Some of these details are given in second total diet study, carried out in China in 1992 [48]. The total diet composition as well as the average daily consumption of each food for Chinese adults, engaged in light physical activity was calculated for each region. Based on the composition of diet and individual food materials, all foods and the products derived from them were classified into the following 13 types: (1) Grain; (2). Beans and nuts; (3) Yam; (4) Meat (including poultry); (5) Egg; (6) Aquatic foods; (7) Milk; (8) Vegetable; (9) Fruits and its salads, etc.; (10) Sugar; (11) Soft beverages and drinking water; (12) Alcoholic beverages; (13) Spices and cooking oil. These foods were collected in 1997 from nearby vegetable markets, subsidiary food stores and farmer markets within the three-survey points in each region. Various foods thus collected were treated and cooked according to the local dietary habit in assigned restaurants and kitchens. Cooked foods were then ground and mixed in the blender. In all, 48 individual food samples were obtained representing the four regions. Samples under frozen condition were shipped to the analytical laboratory for further processing and analysis. All possible precautions already stated in the sampling and quality control chapter were taken to avoid contamination of samples

    Francisco Rufino Diogo, Jose; Shubber, Ammar Abbas Mohammed; Lin, Mu Han

    This study discusses and compares Asphalt Concrete (AC) pavement design methodologies used in China and Mozambique (based on South African Transportation and Communication Commission (SATCC) methodologies). The SATCC design methodologies use California Bearing Ratio (CBR) and catalogues methods. The South African catalogues are basically used for roads with traffic less than 30 million ESAs. The design catalogues method give small thickness than CBR and Chinese methods. The Chinese and the South African design methods give nearly the same thickness; this study concludes that these methods can be used in both countries; China and Mozambique. The results also show that the strong point of Chinese method is verifying the tensile stress and allowable displacement on the pavement calculated from computer program APDS.

    Seismo-electromagnetism is becoming a hot interdisciplinary study in both geosciences and electromagnetism. Numerous electromagnetic changes at a broad range of frequencies associated with earthquakes have been reported independently. There are some attempts of applying such electromagnetic data to short-term earthquake prediction. Although due to the complexity of seismogenic process and underground structure, the seismic electromagnetic phenomena cannot be fully understood, the seismic electromagnetic study plays a key role in the mitigation of seismic hazard. China is one of the countries which have the earliest reports on seismo-electromagnetic phenomena. The seismic electromagnetic study in China started in late 1960's. There are almost 50 years continuous observation data up to now, which provides a unique database for seismo-electromagnetic study not only in China, but also in the world. Therefore, seismo-electromagnetic study in China is interested broadly by international communities of geosciences and electromagnetism. I present here a brief review on seismic electromagnetic study in China, especially focusing on geo-electromagnetic observation and empirical prediction based on the observation data. After summarizing various electromagnetic observations such as apparent resistivity, geoelectric potential, geomagnetic field, electromagnetic disturbance, and so on, I show the cases of the empirical prediction based on the observed electromagnetic data associated with some earthquakes in China. Finally, based on the above review, I propose an integrated research scheme of earthquake-related electromagnetic phenomena, which includes the interaction between appropriate observations, robust methodology of data processing, and theoretical model analysis. This study is supported partially by the National Natural Science Foundation of China (41274075) and the National Basic Research Program of China (2014CB845903).

    Full Text Available This paper presented a case study of the failure mechanisms and support design for deep composite soft rock roadway in the Yangcheng Coal Mine of China. Many experiments and field tests were performed to reveal the failure mechanisms of the roadway. It was found that the surrounding rock of the roadway was HJS complex soft rock that was characterized by poor rock quality, widespread development of joint fissures, and an unstable creep property. The major horizontal stress, which was almost perpendicular to the roadway, was 1.59 times larger than the vertical stress. The weak surrounding rock and high tectonic stress were the main internal causes of roadway instabilities, and the inadequate support was the external cause. Based on the failure mechanism, a new support design was proposed that consisted of bolting, cable, metal mesh, shotcrete, and grouting. A field experiment using the new design was performed in a roadway section approximately 100 m long. Detailed deformation monitoring was conducted in the experimental roadway sections and sections of the previous roadway. The monitoring results showed that deformations of the roadway with the new support design were reduced by 85–90% compared with those of the old design. This successful case provides an important reference for similar soft rock roadway projects.

In some patients diagnosed as Japanese encephalitis or unknown fever, an increase of Coltivirus IgG antibody of fourfold, or more, has been detected using ELISA. Similarly, Coltivirus IgM antibody was positive in some patients with Japanese encephalitis or viral encephalitis. From most Chinese patients, except the northeastern, the isolates of Coltiviruses belong to subgroup B2, according to RT-PCR amplification of the ninth and twelfth segments of the isolates and sequence analysis of their amplicons. Some biological properties of Chinese Coltiviruses isolates are different from that of North American Coltiviruses.Conclusions The isolates of Coltiviruses from Chinese patients are one of the common agents causing viral encephalitis and unknown fever in summer-autumn season. It might be an important public health problem due to its high isolation rate and wide distribution in China. Mosquito is the main transmission vector of the virus.

    Several small reservoirs and a large number of check dams had been constructed in the Wangkuai reservoir watershed after 1970s, and flood time series lacked stationarity, which affected the original design flood hydrographs for the Wangkuai reservoir. Since the location, storage capacity and drainage area of the large number of check dams were unknown, we present a method to estimate their total storage capacities (TSC) and total drainage areas (TDA) by using the recorded rainstorm and flood data. On the basis of TSC and TDA, the flood events which occurred in an undisturbed period were reconstructed under current conditions to obtain a stationary flood series. A frequency analysis was subsequently performed to assess the design flood peak and volume for both small and medium design floods with a 10-200 year return period. For large and catastrophic floods, it was assumed that the upstream check dams and small reservoirs would be destroyed, and water stored in these hydraulic structures were re-routed to the Wangkuai reservoir by unit hydrograph. The modified flood peak and volume decreased for floods with a 10-200 year return period when compared to the current design flood. But for large design floods with a return period exceeding 500 years, peak discharge increased. This study provides a new method for design flood calculation or modification of the original design flood in watersheds with a large number of check dams.

    2008-01-01

    Spatial and temporal distribution of vegetation net primary production (NPP) in China was studied us-ing three light-use efficiency models (CASA, GLOPEM and GEOLUE) and two mechanistic ecological process models (CEVSA, GEOPRO). Based on spatial and temporal analysis (e.g. monthly, seasonally and annually) of simulated results from ecological process mechanism models of CASA, GLOPEM and CEVSA, the following conclusions could be made: (1) during the last 20 years, NPP change in China followed closely the seasonal change of climate affected by monsoon with an overall trend of increas-ing; (2) simulated average seasonal NPP was: 0.571±0.2 GtC in spring, 1.573±0.4 GtC in summer, 0.6±0.2 GtC in autumn, and 0.12±0.1 GtC in winter. Average annual NPP in China was 2.864±1 GtC. All the five models were able to simulate seasonal and spatial features of biomass for different ecological types in China. This paper provides a baseline for China's total biomass production. It also offers a means of estimating the NPP change due to afforestation, reforestation, conservation and other human activities and could aid people in using for-mentioned carbon sinks to fulfill China's commitment of reducing greenhouse gases.

  1. Conceptual design of China fusion power plant FDS-II

    International Nuclear Information System (INIS)

    As one of the series of fusion system design concepts developed by the FDS Team of China, FDS-II is designated to exploit and evaluate potential attractiveness of fusion energy application for the generation of electricity on the basis of conservatively advanced plasma parameters, which can be limitedly extrapolated from the successful operation of ITER. The principle of the blanket design is established in both the feasibility and potential attractiveness of technology to meet the requirement for tritium self-sufficiency, safety margin, operation economy and environment protection etc. The plasma physics and engineering parameters of FDS-II are selected on the basis of the progress in recent experiments and associated theoretical studies of magnetic confinement fusion plasma with a fusion power of 2∝3 GW. The neutron wall load of 2∝3 MW/m2 and the surface heat flux of 0.5∝1 MW/m2 are considered for high effective power conversion. The ''multi-modules'' scenario is adopted in the FDS-II blanket design to reduce thermal stress and electromagnetic forces under plasma disruption, with liquid metal lithium lead (LiPb) as tritium breeder, the Reduced Activation Ferritic/Martensitic (RAFM) steel as structural material. Two options of specific liquid LiPb blanket concepts have been proposed, named the Dual-cooled Lithium Lead (DLL) breeder blanket and the Quasi-Static Lithium Lead (SLL) breeder blanket. The DLL blanket is a dual-cooled LiPb breeder system with helium gas to cool the first wall and main structure and LiPb eutectic to be self-cooled. The flow channel inserts (FCIs), e.g. SiCf/SiC composites, are designed as the thermal and electrical insulators inside the LiPb flow channels to reduce the magnetohydrodynamic (MHD) pressure drop and to allow the coolant LiPb outlet temperature up to 700 C for high thermal efficiency. The SLL blanket is another option of the FDS-II blanket with the technology developed relatively easily. To avoid or mitigate the problems

    Full Text Available Background: While integrated health care system has been proved an effective way to help improving patient health and system efficiency, the exact behaviour model and motivation approach are not so clear in poor rural areas where health human resources and continuous service provision are urgently needed. To gather solid evidence, we initiated a comprehensive intervention project in Qianjiang District, southwest part of rural China in 2012. And after one-year's pilot, we developed an intervention package of team service, comprehensive pathway and prospective- and performance-based payment system.Methods: To testify the potential influence of payment interventions, we use clustered randomised controlled trial, 60 clusters are grouped into two treatment groups and one control group to compare the time and group differences. Difference-in-differences model and structural equation modelling will be used to analyse the intervention effects and pathway. The outcomes are: quality of care, disease burden, supplier cooperative behaviour and patient utilisation behaviour and system efficiency. Repeated multivariate variance analysis will be used to statistically examine the outcome differences.Discussion: This is the first trial of its kind to prove the effects and efficiency of integrated care. Though we adopted randomised controlled trial to gather the highest rank of evidence, still the fully randomisation was hard to realise in health policy reform experiment. To compensate, the designer should take efforts on control for the potential confounders as much as possible. With this trial, we assume the effects will come from: (1 improvement on the quality of life through risk factors control and lifestyles change on patient's behaviours; (2 improvement on quality of care through continuous care and coordinated supplier behaviours; (3 improvement on the system efficiency through active interaction between suppliers and patients

  4. Policy design of the Hubei ETS pilot in China

    International Nuclear Information System (INIS)

    Of seven pilot emissions trading schemes (ETS) being run in China, the ETS in Hubei province is the only provincial pilot in the central and western regions of the country with a high GDP growth rate and heavy industrial structure. As such, it is quite representative of China as a whole and its ETS will therefore be reasonably characteristic of a future nationwide market. This paper describes the policy design of the Hubei ETS, including aspects of coverage, cap, allowance allocation, transactions, compliance and penalties. Then, after making a comparison with the other Chinese pilots and emissions trading schemes in the European Union (EU) and California, the paper offers a summary of several distinct features of the Hubei ETS. First, the small numbers of entities that are covered by the scheme produce a considerable proportion of the emissions. This makes Hubei the world's third largest carbon market. Second, the Hubei ETS applies several mechanisms to deal with the province’s rapid growth rate. Third, the scheme's policy design emphasizes liquidity. In addition to these unique features, the Hubei ETS also shares some common features with all the pilots in China. - Highlights: • The Hubei ETS covers only small numbers of entities but considerable emissions. • The Hubei ETS applies several mechanisms to deal with the rapid economic growth. • The Hubei ETS has the greatest proportion of reserve for capacity extension. • Hubei sets more flexible ex-post adjustment of firms’ allowances. • The Hubei ETS emphasizes liquidity

    2002-01-01

    Prochlorococcus, a tiny oxygenic photosynthetic picoplankton with unique pigment composition, has been found to be ubiquitous and abundant in the world oceans, and has been recognized to be closely related to living resources and environmental issues. It has attracted the interest of marine biologists since its discovery, and field data on it over global oceans have accumulated rapidly in the past 10 years. In China, we have studied Prochlorococcus for 8 years, achieving a basic ecological understanding. The presence of Prochlorococcus in China seas, marginal seas of the west Pacific, was confirmed, and its distribution patterns were also brought to light. Prochlorococcus is very abundant in the South China Sea and the offshore regions of the East China Sea. It is seasonally present in the southeast part of the Yellow Sea and absent in the Bohai Sea. Temporal and spatial variations of the abundance of Prochlorococcus and their affecting factors, physiological and ecological characteristics of Prochlorococcus and their relationships to the other groups of picoplankton, and the importance of Prochlorococcus in total biomass and possible roles in living resources and environmental problems are discussed. In the future, isolation of different Prochlorococcus strains from the China seas and their physiological characteristics, genetic diversity, phylogenies and gene exploiture, etc. are important issues to be addressed.

    2005-01-01

    Rural tourism has long been considered the means of accelerating economic and social development,and has become a development tool for many rural areas. In response to agricultural structure adjustment, rural tourism in China took into shape as a new economic growth point to meet the market demand at the late 1980s.Now, a structural frame of rural tourism has shaped, with the core of Zhujiang (Pearl) River Delta, Beijing, Shanghai and Chengdu of China. But in Xinjiang, the westem part of China, there are hardly any studies in this field in spite of its richness of tourism resources. In this paper, development of rural tourism is studied in Turpan of Xinjiang Uygur Autonomous Region. With its rich natural and cultural tourism resources, Turpan has become one of the pioneer tourism destinations in China. But same to the rural tourism development of the other areas' of China, rural tourism programs in Turpan mainly aimed at sightseeing activities, and little attention had been paid to the protection and exploitation of national minority culture-an important factor to satisfy both tourists demand and local economic development. However, this kind of rural tourism development policy is harmful on the long run. Because, many tourists seek tourist destinations that offer pleasant experiences related to not only the natural environment but also historic heritage and cultural patterns. The study suggests that on the base of government support in the long term, to enhance tourism training, to protect and exploit national minority culture are essential elements of rural tourism development in Turpan.

    The aim of the prospective study reported here was to examine the effects of social and economic transformation on dietary patterns and nutritional status in China. The study began in 1989 and continued with follow-ups in 1991, 1993, 1997, 2000, and 2004. A total of 5000 subjects aged 18-45 years from 4280 households in nine provinces were included. Weighed records and three consecutive 24-h recalls were used. Over the study period, average consumption of all animal foods except milk increased, while cereal intake decreased. The proportion of animal protein and fat as a percentage of energy also increased. However, vitamin A and calcium intake did not increase and remained low. Child height and weight increased while undernutrition decreased and overweight increased. The results indicate that rapid changes in dietary pattern are associated with economic reforms in China.

    Full Text Available At the furthest reach from Ireland – whether in terms of size or geography or culture – China seems an unlikely place for Irish Studies. Yet over the last few years, Irish Studies has emerged as an acknowledged academic field in several key Chinese universities. This essay looks at the obstacles to Irish Studies in China as well as Ireland’s importance, after the fall of the Qing dynasty in 1911, in opening up discussion of such domestic issues as the role of literature in establishing a new national identity. The many unexpected similarities between Irish and Chinese culture have ensured that translations of Irish writers such as Wilde, Yeats, Shaw, Beckett and especially Joyce have played a distinctive role in ushering a newly emerging Chinese nation into its own version of global modernity.

    @@ INTRODCTlON Gallstone is one of the common primary diseases of bile system. Chinese researchers have done comprehensive and thorough studies on it, but there are still some problems we have not solved. It is necessary to review the achievements we have made in this field recently, to summarize the experiences and find the tendency so as to provide a sound foundation for the researches in the new century. Due to the popularization of molecular biological research methods, a rapid development of modern imaging techniques and medical equipment, the basic and clinical studies of cholelithiasis have set foot on the fast lane. Studies on the cause of cholelithiasis formation and its prevention have covered areas from epidemiological investigation at macroscopical level to molecular biological researches at microcosmic level. Clinical studies include prevention and treatment of cholelithiasis with traditional Chinese medicine, popularization of micro-injury surgery,treatment of complicated calculus of bile duct, and other aspects.

    China is not rich in natural forest sources. Owing to natural and historical factors, forest fires have long been frequenting China. Forest fire prevention is the most important of all. Forest fire prevention and controlling have long been held as a very important factor in our ecological plans. Taking china 's special geographical location, topography, climate and the distribution of forest sources into consideration, we have every reason to believe that forest fires in China have their own special env...

    The objective of these studies was to perform a realistic evaluation of the relative costs of tublar-fixed-bed and slurry reactors for methanol, mixed alcohols and Fischer-Tropsch syntheses under conditions where they would realistically be expected to operate. The slurry Fischer-Tropsch reactor was, therefore, operated at low H{sub 2}/CO ratio on gas directly from a Shell gasifier. The fixed-bed reactor was operated on 2.0 H{sub 2}/CO ratio gas after adjustment by shift and CO{sub 2} removal. Every attempt was made to give each reactor the benefit of its optimum design condition and correlations were developed to extend the models beyond the range of the experimental pilot plant data. For the methanol design, comparisons were made for a recycle plant with high methanol yield, this being the standard design condition. It is recognized that this is not necessarily the optimum application for the slurry reactor, which is being proposed for a once-through operation, coproducing methanol and power. Consideration is also given to the applicability of the slurry reactor to mixed alcohols, based on conditions provided by Lurgi for an Octamix{trademark} plant using their standard tubular-fixed reactor technology. 7 figs., 26 tabs.

    2006-06-01

    Full Text Available Abstract Nasopharyngeal carcinoma (NPC is a complex disease caused by a combination of Epstein-Barr virus chronic infection, the environment and host genes in a multi-step process of carcinogenesis. The identity of genetic factors involved in the development of chronic Epstein-Barr virus infection and NPC remains elusive, however. Here, we describe a two-phase, population-based, case-control study of Han Chinese from Guangxi province, where the NPC incidence rate rises to a high of 25-50 per 100,000 individuals. Phase I, powered to detect single gene associations, enrolled 984 subjects to determine feasibility, to develop infrastructure and logistics and to determine error rates in sample handling. A microsatellite screen of Phase I study participants, genotyped for 319 alleles from 34 microsatellites spanning an 18-megabase region of chromosome 4 (4p15.1-q12, previously implicated by a linkage analysis of familial NPC, found 14 alleles marginally associated with developing NPC or chronic immunoglobulin A production (p = 0.001-0.03. These associations lost significance after applying a correction for multiple tests. Although the present results await confirmation, the Phase II study population has tripled patient enrolment and has included environmental covariates, offering the potential to validate this and other genomic regions that influence the onset of NPC.

  14. ATW neutronics design studies

    International Nuclear Information System (INIS)

    The Accelerator Transmutation of Waste (ATW) concept has been proposed as a transuranics (TRU) (and long-lived fission product) incinerator for processing the 87,000 metric tonnes of Light Water Reactor used fuel which will have been generated by the time the currently deployed fleet of commercial reactors in the US reach the end of their licensed lifetime. The ATW is proposed to separate the uranium from the transuranics and fission products in the LWR used fuel, to fission the transuranics, to send the LWR and ATW generated fission products to the geologic repository and to send the uranium to either a low level waste disposal site or to save it for future use. The heat liberated in fissioning the transuranics would be converted to electricity and sold to partially offset the cost of ATW construction and operations. Options for incineration of long-lived fission products are under evaluation. A six-year science-based program of ATW trade and system studies was initiated in the US FY 2000 to achieve two main purposes: (1) ''to evaluate ATW within the framework of nonproliferation, waste management, and economic considerations,'' and (2) ''to evaluate the efficacy of the numerous technical options for ATW system configuration.'' This paper summarizes the results from neutronics and thermal/hydraulics trade studies which were completed at Argonne National Laboratory during the first year of the program. Core designs were developed for Pb-Bi cooled and Na cooled 840 MWth fast spectrum transmuter designs employing recycle. Additionally, neutronics analyses were performed at Argonne for a He cooled 600 MWth hybrid thermal and fast core design proposed by General Atomics Co. which runs critical for 3/4 and subcritical for 1/4 of its four year once-thin burn cycle. The mass flows and the ultimate loss of transuranic isotopes to the waste stream per unit of heat generated during transmutation have been calculated on a consistent basis and are compared.

    The author selects a thorny issue of doubled designations that bother policy-makers, professional planners and managers in the field of conservation for protected areas. The analyzed case study areas cover 5 National Geoparks of China in Sichuan Province, 18 UNESCO Global Geoparks in China, and 219 World Heritage sites in China and 8 European nations. Through analysis and synthesis, the author concludes that doubled designation, which also leads to unbalanced park distribution, is particularly prevalent in China other than in Europe. Therefore, on-site management agencies and related governments in China should carefully translate the doubled designations into responsibilities and harmonious partnerships between all stakeholders in order to enhance the management effectiveness and avoid paper park phenomenon.

A number of neuroimaging studies have investigated the etiology of anxiety disorders in China in the last decade. We discuss the findings of these studies, and compare them with the results of neuroimaging studies of anxiety disorders outside China.Method: A literature search was conducted using the Chinese BioMedical Literature Database, the Chinese Scientific and Technical Periodicals Database, the Chinese Journal Full-text Database, and PubMed, from 1989 to April 2009. We selected neuroimaging studies in which all participants and researchers were Chinese.Results: Twenty-five studies fit our inclusion criteria. Nine studies examined general anxiety disorder (GAD and/or panic disorder (PD, eight examined obsessive-compulsive disorder (OCD, and eight examined posttraumatic stress disorder (PTSD. Our literature review revealed several general findings. First, reduced regional cerebral blood flow (rCBF was found in the frontal lobe and temporal lobe in patients with GAD and PD compared with healthy controls. Second, when viewing images with negative and positive valence, relatively increased or decreased activation was found in several brain areas in patients with GAD and PD, respectively. Third, studies with positron emission tomography (PET and magnetic resonance spectroscopy (MRS imaging revealed that OCD patients exhibited hyperperfusion and hypoperfusion in some brain regions compared with healthy controls. Neuroimaging studies of PTSD indicate that the hippocampal volume and the N-acetylaspartic acid (NAA level and the NAA/creatine ratio in the hippocampus are decreased in patients relative to controls.Conclusion: Neuroimaging studies within and outside China have provided

  1. Characteristics of the population studies in China.

    Liu, C

    1989-01-01

    The author presents a brief historical sketch of the origins of Chinese population studies and provides 8 characteristics of the post-1978 advances made in population science. Chinese scholars were among the 1st to research population issues but ceased their work in the 18th century. In the late 19th century scholars used the theories of Thomas Malthus to explain population growth. This research peaked in the 1st half of the 20th century and continued in the Malthusian tradition and sociological point of view. Soviet theories on population were popular in the 1930's and 40's, and adopted by the administration with the founding of New China in 1949. Sociologically oriented scholars were criticized, even for Marxist views. The 1978 3rd plenary session of the 11th Central Committee of the Chinese Communist Party adopted a policy which emphasized the quest for truth from facts, future planning, and unification. Between 1978-88 huge advances were made in population studies which attracted world attention and contributed to solving China's population problems. Demographic societies were founded at the national, provincial, and municipal levels. Institutions of higher education formed professional departments. Training centers were formed for government family planning officers, and exchanges of students and scholars were made with other countries. An extensive network of party schools and FP departments contributed to population studies. The 8 characteristics which contributed to the originality of the effort were as follows: 1) A blend of Western and Marxist theory was developed. 2) Qualitative and quantitative research was conducted, which surpassed the boring and abstract Soviet research and the Western research short on sociological analyses. 3) Theoretical research was combined with practical research, which lead to the publication of a 30 volume series. 4) Population studies have utilized the theories and methodologies of other related sciences such as economics

  5. Study of space mutation breeding in China

    International Nuclear Information System (INIS)

    This paper described the status of space mutation breeding in China. It emphasized that since 1978 Chinese space scientists and agricultural biologists have send 50 kg seeds of more than 70 crops including cereals, cotton, oil, vegetable, fruit and pasture to the space using the facilities such as return satellite 9 times, Shenzhou aircraft twice and high balloon 4 times. New varieties of 19 with high yield, high quality and disease-resistance, have been bred though years of breeding at the earth at more than 70 Chinese research institutes in 22 provinces. The new varieties include five rice varieties, two wheat varieties, two cotton varieties, one sweat pepper, one tomato variety, one sesame variety, three water melon varieties, three lotus varieties and one ganoderma lucidum variety. In addition more than 50 new lines and many other germplasm resources have been obtained. Study on space breeding mechanism, such as biological effect of space induction, genetic variation by cell and molecular techniques and simulated study at the earth, has been conducted, and some progresses have been achieved. Many space-breeding bases have been established in some provinces. Space varieties have been extended up to 270000 hectares, and some useful scientific achievements and social economic benefit had been made. The study of Chinese space mutation breeding is going ahead in the world. The paper also introduced the contribution and results made by return satellites of the first three generation in space science.

    2015-10-01

    At Shantou University (STU) in 2008, a stand-alone engineering ethics course was first included within a Conceive-Design-Implement-Operate (CDIO) curriculum to address the scarcity of engineering ethics education in China. The philosophy of the course design is to help students to develop an in-depth understanding of social sustainability and to fulfill the obligations of engineers in the twenty-first century within the context of CDIO engineering practices. To guarantee the necessary cooperation of the relevant parties, we have taken advantage of the top-down support from the STU administration. Three themes corresponding to contemporary issues in China were chosen as the course content: engineers' social obligations, intellectual property and engineering safety criteria. Some popular pedagogies are used for ethics instruction such as case studies and group discussions through role-playing. To impart the diverse expertise of the practical professional practice, team teaching is adopted by interdisciplinary instructors with strong qualifications and industrial backgrounds. Although the assessment of the effectiveness of the course in enhancing students' sense of ethics is limited to assignment reports and class discussions, our endeavor is seen as positive and will continue to sustain the CDIO reform initiatives of STU.

    2003-01-01

    @@ Many significant progresses of earth science in the mid to late 20th century were closely related to the international Deep Sea Drilling Program (DSDP). The sedimentary record obtained from underneath several thousands of seawater opened a new window for mankind to understand the Earth and its evolution. The Chinese earth science community learned the DSDP through the introduction of the plate tectonic theory in the 1970s, but deep-sea study remained remote and unrealistic for the then China. The onset of the Ocean Drilling Program (ODP) in 1985 triggered the hope for China to be involved in the international paleoceanographic studies. With the establishment of an "Ocean Drilling Program Committee of China", the aim was to bring China onto the new international frontier of science, but little could be done because of the lack of necessary conditions at the time.

    2015-01-01

    This study investigates the optimal reinsurance for crop insurance in China in an insurer’s perspective using the data from Inner Mongolia, Jilin, and Liaoning, China. On the basis of the loss ratio distributions modeled by AnHua Crop Risk Evalu-ation System, we use the empirical model developed by Tan and Weng (2014) to study the optimal reinsurance design for crop insurance in China. We ifnd that, when the primary insurer’s loss function, the principle of the reinsurance premium calculation, and the risk measure are given, the level of risk tolerance of the primary insurer, the safety loading coefifcient of the reinsurer, and the constraint on reinsurance premium budget affect the optimal reinsurance design. When a strict constraint on reinsurance premium budget is implemented, which often occurs in reality, the limited stop loss reinsurance is optimal, consistent with the common practice in reality. This study provides suggestions for decision making regarding the crop reinsurance in China. It also provides empirical evidence for the literature on optimal reinsurance from the insurance market of China. This evidence undoubtedly has an important practical signiifcance for the development of China’s crop insurance.

  3. Progress of the Keda Torus eXperiment Project in China: design and mission

    International Nuclear Information System (INIS)

    The Keda Torus eXperiment (KTX) is a medium-sized reversed field pinch (RFP) device under construction at the University of Science and Technology of China. The KTX has a major radius of 1.4 m and a minor radius of 0.4 m with an Ohmic discharge current up to 1 MA. The expected electron density and temperature are, respectively, 2 × 1019 m−3 and 800 eV. A combination of a stainless steel vacuum chamber and a thin copper shell (with a penetration time of 20 ms) surrounding the plasma provides an opportunity for studying resistive wall mode instabilities. The unique double-C design of the KTX vacuum vessel allows access to the interior of the KTX for easy first-wall modifications and investigations of power and particle handling, a largely unexplored territory in RFP research leading to demonstration of the fusion potential of the RFP concept. An active feedback mode control system is designed and will be implemented in the second phase of the KTX program. The recent progress of this program will be presented, including the design of the vacuum vessel, magnet systems and power supplies. (paper)

    This discussion of China focuses on the following: the people; geography; history (early history, 20th century China, the People's Republic of China; the "Great Leap Forward" and the Sino Soviet Split, the Cultural Revolution, and Mao's death and present directions); government (state structure, Chinese Communist Party, and legal system); education; economy; foreign relations; defense; and relations between China and the US. As of 1982, China's population totaled just over 1.008 billion with an annual growth rate of 1.5%. Life expectancy is 68 years. Government authorities endorsed birth control in the 1950s, played it down in 1958, and began to promote it again in 1962. The present family planning program began in the early 1970s and has become more fully mobilized since 1979. The largest ethnic group is the Han Chinese, who constitute 93.3% of the total population. The People's Republic of China, located in eastern Asia, is almost as large as the European continent. 2/3 of China's area is mountainous or semidesert; only about 1/10 is cultivated. China is the oldest continuous major world civilization with records dating back about 3500 years. Mao's death in September 1976 removed a towering figure from Chinese politics and set off a scramble for succession. The post 11th Party Congress leadership has emphasized economic development and renounced the mass political movements of prior years. Important educational reforms were made in early 1978. Since 1979, the Chinese leadership has moved toward more pragmatic positions in almost all fields. The Chinese government has always been subordinate to the Chinese Communist Party (CCP), its role being to implement party policies. The primary instruments of state power are the State Council, an executive body corresponding to a cabinet, and the NPC, a legislative body. China has made impressive progress in primary education since 1949. About 93% of eligible children are enrolled in 1st grade, though only 65% finish primary

  7. China

    International Nuclear Information System (INIS)

    This paper reports on the reason for China's future nuclear policy. First, assuming a continued decline in superpower influence, China's focus will be on regional issues. The policies of Japan, the NICs and other Chinese neighbors will be more relevant than those of the superpowers. Second, Chinese domestic politics will have to resume the road to reform. A more unstable and suspicious Chinese leadership will perceive a more hostile and unstable world. Even when China was on the path to reform, its foreign relations were not always peaceful. However, it would be wrong to suggest that even a more xenophobic and unstable Chinese leadership would necessarily expand China's nuclear capability or lead China into a major war. Even at the height of the Cultural Revolution, Chinese foreign policy was careful, nuclear proliferation was avoided and crises were well-managed. Still China's basic domestic and foreign policy needs will likely remain unfulfilled for the foreseeable future. Furthermore, although the East Asian balance of power may not appear to be particularly dangerous at present, there is enough uncertainty to ensure that China remains a nuclear power and a maverick one at that at least in the near term

    Laws and regulations about the forensic psychiatric systems in China and America were compared, and suggestions for improving the forensic psychiatric system of China were provided. There are many differences regarding the role of the forensic psychiatrist, the initiation of the assessment and the admission of expert opinion because of elements in the legal systems in China and America. The Chinese system has the advantages of objectivity, cost saving and high efficiency; but it has deficiencies in procedural justice and the admission of expert opinion. China can persist with the current system while taking measures to give more rights to the litigants to participate in their assessment, and while improving the quality and utility of the expert opinion; however, this review article will compare broadly the two systems without addressing human rights issues or procedural justice issues, nor will it presume to address the entirety of Chinese systems. In addition, China is developing its legal system for dealing with the mentally ill defendant in situations involving the criminal justice system and civil commitment. Although China enacted new laws regarding the mandatory treatment for the mentally ill, both in criminal and civil systems, there remain many aspects to be improved, including but not limited to a system of review of the decision to detain a patient on psychiatric grounds, and the need for provisions in the laws preventing indefinite detention. From this viewpoint, America's laws and regulations are instructive for us, in matters such as the method of dealing with the mentally ill defendant who is "incompetent to stand trial", "not guilty only by reason of insanity" or "guilty but mentally ill". The conditional release of the committed mentally ill person and the special programs in the forensic security hospital are all worthy of study by China in order to manage the mentally ill offender and to reduce the recidivism rate.

  12. Design and tritium permeation analysis of China HCCB TBM port cell

    International Nuclear Information System (INIS)

    China is planning to develop a helium-cooled ceramic breeder (HCCB) test blanket module (TBM) on ITER to test key blanket technologies. In this paper, the design and tritium permeation analysis of China HCCB TBM port cell are introduced. A theoretical model has been developed to estimate tritium permeation rates and leak rates from the components and pipes which China has scheduled to house in the port cell. It is shown that on normal working conditions, the permeation and leak rate of the systems in the port cell will be no higher than 1.58 Ci/d without the use of tritium permeation barriers, and 0.10 Ci/d with the use of tritium permeation barriers. It also appears that tritium permeation barriers are necessary for high temperature components such as the reduction bed and the heater

    Full Text Available China has the richest offshore wind resource in the world. Much of undeveloped resource should consider floating tension leg platform (TLP wind turbine because of its advantage and potential in cost and safety for deep sea, but the related research is short in China. In this thesis we assess a preliminary design for a type of TLP structure in the South China Sea (SCS-TLP closed to Guangdong province basing on NREL 5MW wind turbine. By coupled analysis in the time domain, the platform displacement and tower base force are obtained and analyzed. As a result, SCS-TLP has good features in the dynamic response except yaw motion, it needs to improve the yaw direction damping to induce motion in this direction.

  14. Institutional Design for Strategic Environmental Assessment on Urban Economic and Social Development Planning in China

    International Nuclear Information System (INIS)

    The National Economic and Social Development Plans (NESDPs) of cities in China, given their comprehensive, integrated and strategic nature, have significant and profound impacts on the development of cities and their embedded ecological environments. Strategic Environmental Assessments (SEAs) on city NESDPs have the potential to improve environmental policy integration at strategic level and to safeguard the sustainable development of cities. However, these plans are normally exempted from the current SEA requirement in China. We argue that it is more feasible to apply SEAs on city NESDPs before SEAs are expanded to higher level NESDPs in China. This article attempts to propose a China-specific institutional design for SEAs on city NESDPs based on experiments in selected cities and within the current legal framework. To obtain a holistic view about the long-term development of cities, more qualitative and descriptive analysis-based assessment methods should be adopted to broaden participation, to encourage the exchange of information and to reach consensus. - Highlights: → National Economic and Social Development Plans for Cities (NESDPs) in China is a very popular and significant decision made by municipal government. → We propose a institutional framework to conduct strategic environmental assessment to NESDPs. → The key features of the institutional framework are the independent SEA approval committee and a professional consulting agency.

    This paper describes the design of the advanced nuclear power plant ACP1000 in China that keeps the principle of defence in depth. To enhance the safety of the new generation NPPs, passive and active engineering safety features are used. The reactor will be kept safe under design basis accidents by using active engineering safety features, such as the medium and low pressure safety injection systems, and the emergency feedwater system. Under beyond DBAs, the passive safety systems will be actuated to keep removing residual heat for more than 72 hours, and to keep the core melt retained and cooled in the vessel. After the Fukushima nuclear accident, there are six main design enhancements in ACP1000 to meet the demands of the China authorities. (author)

    International Nuclear Information System (INIS)

    Based on the complex system theory and the concept of self organized criticality (SOC) theory, the mechanism of China power grid blackout is studied by analyzing the blackout data in the China power system from 1981 to 2002. The probability distribution functions of various measures of blackout size have a power tail. The analysis of scaled window variance and rescaled range statistics of the time series show moderate long time correlations. The blackout data seem consistent with SOC; the results obtained show that SOC dynamics may play an important role in the dynamics of power systems blackouts. It would be possible to propose novel approaches for understanding and controlling power systems blackouts

    2014-09-01

    Full Text Available Attempts at flood management during the 20th century resulted in more flood disasters. To gain a better understanding of what went wrong, it is necessary to examine historical evidence, seek ancient wisdom and compare practices of flood management in different countries. This study examines flood management concepts and practices in China and Japan during different periods of time in history and the differences in the two countries’ current management of flood retarding basins. It reveals that during the Western Han Dynasty (206 BC–24 AD, China proposed to redirect a river course to gain sufficient flood retarding capacity, and this same concept was realized, either coincidentally or intentionally, during the Edo period of Japan (1603–1868. In modern times, however, the management of flood retarding basins differs fundamentally between China and Japan. In addition, this study investigates the differences in emergency evacuation practices between China and Japan. This is the first study to highlight the link between a Chinese concept and a Japanese practice that are separated by more than 1000 years.

    Since the last International Union of Geodesy and Geophysics (IUGG) General Assembly (1999), the predictability studies in China have made further progress during the period of 1999-2002. Firstly, three predictability sub-problems in numerical weather and climate prediction are classified, which are concerned with the maximum predictability time, the maximum prediction error, and the maximum allowable initial error, and then they are reduced into three nonlinear optimization problems. Secondly, the concepts of the nonlinear singular vector (NSV) and conditional nonlinear optimal perturbation (CNOP) are proposed,which have been utilized to study the predictability of numerical weather and climate prediction. The results suggest that the nonlinear characteristics of the motions of atmosphere and oceans can be revealed by NSV and CNOP. Thirdly, attention has also been paid to the relations between the predictability and spatial-temporal scale, and between the model predictability and the machine precision, of which the investigations disclose the importance of the spatial-temporal scale and machine precision in the study of predictability. Also the cell-to-cell mapping is adopted to analyze globally the predictability of climate,which could provide a new subject to the research workers. Furthermore, the predictability of the summer rainfall in China is investigated by using the method of correlation coefficients. The results demonstrate that the predictability of summer rainfall is different in different areas of China. Analysis of variance, which is one of the statistical methods applicable to the study of predictability, is also used to study the potential predictability of monthly mean temperature in China, of which the conclusion is that the monthly mean temperature over China is potentially predictable at a statistical significance level of 0.10. In addition,in the analysis of the predictability of the T106 objective analysis/forecasting field, the variance and

    An overview of basic research on climate change in recent years in China is presented. In the past 100 years in China,average annual mean surface air temperature (SAT) has increased at a rate ranging from 0.03℃ (10 yr)-1 to 0.12℃ (10 yr)-1.This warming is more evident in northern China and is more significant in winter and spring.In the past 50 years in China,at least 27% of the average annual warming has been caused by urbanization.Overall,no significant trends have been detected in annual and/or summer precipitation in China on a whole for the past 100 years or 50 years. Both increases and decreases in frequencies of major extreme climate events have been observed for the past 50 years. The frequencies of extreme temperature events have generally displayed a consistent pattern of change across the country,while the frequencies of extreme precipitation events have shown only regionally and seasonally significant trends.The frequency of tropical cyclone landfall decreased slightly,but the frequency of sand/dust storms decreased significantly.Proxy records indicate that the annual mean SAT in the past a few decades is the highest in the past 400-500 years in China,but it may not have exceeded the highest level of the Medieval Warm Period (1000-1300 AD).Proxy records also indicate that droughts and floods in eastern China have been characterized by continuously abnormal rainfall periods,with the frequencies of extreme droughts and floods in the 20th century most likely being near the average levels of the past 2000 years.The attribution studies suggest that increasing greenhouse gas (GHG) concentrations in the atmosphere are likely to be a main factor for the observed surface warming nationwide.The Yangtze River and Huaihe River basins underwent a cooling trend in summer over the past 50 years,which might have been caused by increased aerosol concentrations and cloud cover.However,natural climate variability might have been a main driver for the mean and

    Zhou, Chunmei; van Westen, Cees

    2013-04-01

    This study is related to the design of anti-slide piles for several landslides in Wanzhou city located in the Three Gorges area. Due to the construction of the Three Gorges Reservoir the hydro-geological conditions in this area have deteriorated significantly, leading to larger instability problems. China has invested a lot of money in slope stabilization measures for the treatment of landslides in the Three Gorges area. One of the methods for the stabilization of large landslides is the design of anti-sliding piles. This paper focuses on extensive slope stability analysis and modeling of the mechanical behavior of the landslide masses, and the parameters required for designing the number, size and dimensions of reinforced concrete stabilization piles. The study focuses on determining the rock parameters, anchor depth, and the pile and soil interaction coefficient. The study aims to provide guidelines for anti-slide pile stabilization works for landslides in the Wanzhou area. The research work contains a number of aspects. First a study is carried out on the distribution of pressures expected on the piles, using two different methods that take into account the expected pore water pressure and seismic acceleration. For the Ercengyan landslide , the Limit Equilibrium Method and Strength Reduction Method of FEM are compared through the results of the landslide pressure distributions on the piles and stress fields in the piles. The second component is the study of the required anchor depth of antislide piles, which is carried out using a statistical analysis with data from 20 landslides that have been controlled with anti-sliding piles. The rock characteristics of the anchor locations were obtained using laboratory tests, and a classification of rock mass quality is made for the anchors of antislide piles. The relationship between the critical anchor height and the angle of the landslide slip surface is determined. Two different methods are presented for the length

    1993-01-01

    A supersonic airplane creates shocks which coalesce and form a classical N-wave on the ground, forming a double bang noise termed sonic boom. A recent supersonic commercial transport (the Concorde) has a loud sonic boom (over 100 PLdB) and low aerodynamic performance (cruise lift-drag ratio 7). To enhance the U.S. market share in supersonic transport, an airframer's market risk for a low-boom airplane has to be reduced. Computational fluid dynamics (CFD) is used to design airplanes to meet the dual constraints of low sonic boom and high aerodynamic performance. During the past year, a research effort was focused on three main topics. The first was to use the existing design tools, developed in past years, to design one of the low-boom wind-tunnel configurations (Ames Model 3) for testing at Ames Research Center in April 1993. The second was to use a Navier-Stokes code (Overflow) to support the Oblique-All-Wing (OAW) study at Ames. The third was to study an optimization technique applied on a Haack-Adams body to reduce aerodynamic drag.

  10. Design Evolution Study - Aging Options

    International Nuclear Information System (INIS)

    The purpose of this study is to identify options and issues for aging commercial spent nuclear fuel received for disposal at the Yucca Mountain Mined Geologic Repository. Some early shipments of commercial spent nuclear fuel to the repository may be received with high-heat-output (younger) fuel assemblies that will need to be managed to meet thermal goals for emplacement. The capability to age as much as 40,000 metric tons of heavy metal of commercial spent nuclear he1 would provide more flexibility in the design to manage this younger fuel and to decouple waste receipt and waste emplacement. The following potential aging location options are evaluated: (1) Surface aging at four locations near the North Portal; (2) Subsurface aging in the permanent emplacement drifts; and (3) Subsurface aging in a new subsurface area. The following aging container options are evaluated: (1) Complete Waste Package; (2) Stainless Steel inner liner of the waste package; (3) Dual Purpose Canisters; (4) Multi-Purpose Canisters; and (5) New disposable canister for uncanistered commercial spent nuclear fuel. Each option is compared to a ''Base Case,'' which is the expected normal waste packaging process without aging. A Value Engineering approach is used to score each option against nine technical criteria and rank the options. Open issues with each of the options and suggested future actions are also presented. Costs for aging containers and aging locations are evaluated separately. Capital costs are developed for direct costs and distributable field costs. To the extent practical, unit costs are presented. Indirect costs, operating costs, and total system life cycle costs will be evaluated outside of this study. Three recommendations for aging commercial spent nuclear fuel--subsurface, surface, and combined surface and subsurface are presented for further review in the overall design re-evaluation effort. Options that were evaluated but not recommended are: subsurface aging in a new

    Fish is one of the most important nutrition sources for humanity. Contaminant exposure risk in fish farming will eventually deliver to the crowd through diet. China is the largest fish producing as well as exporting country, where mariculture plays an important role in fish production, especially in South China. Previous investigations indicated that a variety of compartments in farming areas of South China Sea were polluted by persistent organic pollutants, including DDT (dichlorodiphenyltrichloroethane) and its derivatives, some of which is designated as DDTs. In the present study, Hailing Bay and Daya Bay of Guangdong Province, China, were selected as the study sites and DDTs as the target compounds. A fish enrichment model was developed to assess the relative contributions of various pathways to the mass loadings of DDTs in the fish. Average concentrations (and concentration ranges) of DDTs in various environmental compartments of Hailing Bay and Daya Bay were included in modeling and analysis. Modeling results indicated that fish food and seawater contributed approximately the same proportions for the DDTs in maricultured fish. Antifouling paint was supposed to be the primary source of water DDTs in mariculture zone of Hailing Bay and Daya Bay, which contributed 69 % of the total DDTs to the mariculture water. We suggest that in order to protect people from consuming highly contaminated maricuture zone fish, the most effective and feasible methods are using environment-friendly antifouling paint and applying less polluted fish food in the fish reproduction process.

    Transgender individuals constitute an important focus for HIV prevention, but studies in this population present some unique methodologic and operational challenges. We consider issues related to sampling, sample size, number of sites, and trial cost. We discuss relevant design issues for evaluating interventions in both HIV-negative and HIV-infected transgender populations, as well as a method for assessing the impact of an intervention on population HIV incidence. We find that HIV-endpoint studies of transgender individuals will likely require fewer participants but more sites and have higher operational costs than HIV prevention trials in other populations. Because any intervention targeted to transgender individuals will likely include antiretroviral drugs, small scale studies looking at potential interactions between antiretroviral therapy and hormone therapy are recommended. Finally, assessing the impact of an intervention targeted to transgender individuals will require better information on the contribution of such individuals to the population HIV incidence.

  20. China's self-relied capability of nuclear power design obtained from practice

    International Nuclear Information System (INIS)

    There are altogether 6 NPPs (11 units) in Mainland China, among which 9 units with 6.7GWe have been put into commercial operation while the remaining 2 under construction are expected to connect to the grid by the end of 2005. Till then the total nuclear installed capacity will add up to 8.7GWe. Over recent years, with the rapid and steady development of national economy, constrain of energy shortage on economy and society has become more and more obvious. The State Council and relevant governmental departments have attached great importance to nuclear power development, especially emphasizing that self-reliance and localization in nuclear power industry are key to accelerate nuclear power construction. The China's nuclear power practice in the past two decades tells us that self-relied design is the key to the self-relied development of China's nuclear power industry. It is also the basis of independence in construction, equipment manufacturing, operation management, maintenance, improvement and innovation. To enhance self-relied design capability is an essential way to reduce the construction cost, improve maintenance and provide better technical services. It will ultimately help to make nuclear power safer, more economical and more competitive so as to create a favorable environment for its sustainable development. (authors)

  10. Observation Study of Aerosol Radiative Properities over China

    MAO Jietai; LI Chengcai

    2006-01-01

    With a simplified radiation balance model, study is performed of aerosol direct radiation forcing in relation to its optical properties and surface reflectance, indicating that with the thickened aerosol layer the earth-atmosphere system may increase or weaken the solar radiation albedo, depending upon different combinations of aerosol single scattering albedo (SSA, ω0), asymmetry factor (g), and surface albedo (αg)rather than relying directly on the aerosol optical depth (δ), which has its value just in proportion to the changed range of albedo alone.As indicated by the model results, systematic observations of aerosol radiative properties are required to make quantitative study of aerosol direct radiative forcing. Observational research of the properties has been undertaken based on ground and space measurements over China, including ground-based sunphotometeraerosol optical depth (AOD), nephelometer-aerosol scattering coefficients, aethalometer-aerosol absorption coefficients, and MODIS products-retrieved AOD. The satellite retrieved AOD is validated against in situ sun photometer measured AOD, ind icating that for eastern China remote sensing given AODs are acceptable owing mainly to lower surface reflectance there whereas for poor vegetation in the north of China the surface reflectance may be underestimated in AOD retrieval. However, appropriate modification of the scheme of aerosol remote sensing is likely to improve the retrieval accuracy. The aerosol single scattering albedo in dry condition is around 0.80 from surface-measured scattering and absorption coefficients. It requires further studies based on more observations to improve our understanding of the issue.

    Future accelerator magnets will need to reach higher field in the range of 20 T. This field level is very difficult to reach using only Low Temperature Superconductor materials whereas High Temperature Superconductors (HTS) provide interesting opportunities. High current densities and stress levels are needed to design such magnets. YBCO superconductor indeed carries large current densities under high magnetic field and provides good mechanical properties especially when produced using the IBAD approach. The HFM EUCARD program studies the design and the realization of an HTS insert of 6 T inside a Nb3Sn dipole of 13T at 4.2 K. In the2HTS insert, engineering current densities higher than 250 MA/m under 19 T are required to fulfill the specifications. The stress level is also very severe. YBCO IBAD tapes theoretically meet these challenges from presented measurements. The insert protection is also a critical because HTS materials show low quench propagation velocities and the coupling with the Nb3Sn magnet make...

  14. A Mobile Irradiator Design Study

    International Nuclear Information System (INIS)

    The need for data on the technical and economic feasibility of commercial potato irradiation using Cobalt-60 gamma rays, led to a design and cost study of a mobile irradiator. Investigation of handling and storage of potatoes in major growing areas in Canada and the United States showed that the irradiator should process at least 6,000 lbs. (2,700 kilos) per hour in bulk or in 100 lb. (45 kilo) bags. Tests on irradiated potatoes indicated that a dose of 8,000 rads would effectively inhibit sprouting at a storage temperature of 68oF (20oC). Based on source configurations of other AECL irradiation facilities, calculations and measurements of dosage uniformity were made showing that ±33 per cent variation occurred when using two passes on each side of the line source. The source was designed to have increased activity near the ends. The calculated radiation utilization efficiency was 48 per cent. A truck-mounted irradiator was studied in some detail and was found to be too heavy for easy transportation. An irradiator using a railroad flatcar and weighing 60 tons (54,000 kilos) was then considered. Although its movement is restricted, most potato warehouses are located near railroad sidings and are easily reached by a railroad car. The processing cost, including depreciation, source replacement and operating costs, was estimated to be 0.9 per cent per lb. (2.0 cents per kilo) for 1,200 hours operation per year. A longer operation time per year results in a decrease in this processing cost. The above figure is based on estimated costs for a prototype unit. Somewhat lower costs are indicated for production irradiators. (author)

  19. Design studies of superconducting generators

    International Nuclear Information System (INIS)

    A study of superconducting, central-station turbine-generators of 300 and 1200 MVA rating is reported. A unique construction concept is used for the superconducting field winding. The goal of this construction is to ensure that the winding can be energized to the current and flux density predicted by the superconductor short-sample data, without the ''training'' instabilities frequently encountered in large coils. The remainder of the rotor components includes an aluminum radiation shield and a compound, steel-aluminum electromagnetic shield, designed to withstand short circuit electromagnetic forces. The study was focused on generator model configurations which were proportioned to have a low transient reactance, approximately 0.2 per unit. The critical clearing times calculated were comparable to conventional units, the low reactance offsetting an inherently lower rotor inertia. These configurations are estimated to have about half the size and weight, and about half the losses of conventional units of the same rating. Transient characteristics are described, including the effect of the rotor shielding configuration on rotor damping. 8 refs

    Mooring systems play an important role for semi-submersible rigs that drill in deepwater.A detailed analysis was carried out on the mooring of a semi-submersible rig that conducted a trial well drilling at a deepwater location in the South China Sea in 2009.The rig was 30 years old and had a shallow platform with a designed maximum operating water depth of 457 m.Following the mooring analysis,a mooring design was given that requires upgrading of the rig's original mooring system.The upgrade included several innovations,such as installing eight larger anchors,i.e.replacing the original anchors and inserting an additional 600 m of steel wires with the existing chains.All this was done to enhance the mooring capability of the rig in order for the rig to be held in position to conduct drilling at a water depth of 476 m.The overall duration of the drilling was 50 days and the upgraded mooring system proved to be efficient in achieving the goal of keeping the rig stationary while it was drilling the trial well in the South China Sea.This successful campaign demonstrates that an older semi-submersible rig can take on drilling in deep water after careful design and proper upgrading and modification to the original mooring system.

  4. Reclamation planning for abandoned mining subsidence lands in eastern China: a case study

    International Nuclear Information System (INIS)

    China has a long history of coal mining and more than 96% of coal output is taken from underground mines each year. With the excavation of coal from underground, severe subsidence often results, which produces many subsidence lands. This paper explores the principle and methods of reclamation planning for abandoned mining subsidence lands and presents a case study in eastern China. A 373 ha of abandoned mining subsidence land in Anhui province was selected as an experiment site. Since China is a developing country and land shortage is severe in this area, the high economic benefits from the reclaimed land was the final reclamation goal. Based on the topography of subsidence lands, some parts of the abandoned lands were lands or lake-like troughs, restoring farmlands and fishponds were chosen as post-reclamation land uses. The elevation of reclaimed lands was the key for restoring farmland successfully because of the high underground water level in this area, and the optimum fishpond size and side-slope design were the keys to reach high reclamation income. The HDP (Hydraulic Dredge Pump) reclamation technique was used for restoring farmland and creating fishpond. A farming and aquaculture plan for high economic benefits was also designed. This project will make farmers, who own the lands, richer through reclamation. 3 refs., 5 figs., 1 tab

    The plantation occupies great proportion in urban forest in many cities in China. The design and management for urban forest supplements each other. The design decides the orientation of management, while the management also affects the landscape effects and ecological benefits of the design in reverse. There are many issues on design and management of urban forest. For example, some designs only emphasize the visual impression while ignoring the ecological benefits, the problems of simplifying the forest layer structure and purifying its species composition are ubiquitous, It is short of comprehensive analysis of local environment conditions, the phenomena are very outstanding in learning foreign or other city's model by copying mechanically. The management model is not only monotonous, but also behind the step of urban development and the human demand for returning to nature. These unreasonable designs and managements are one of the main reasons for lower ecological benefits, and also caused some other bad aftereffects, such as lower biodiversity and high cost of management, etc. So the thought of close-to-nature design and management in urban forest is proposed and its feasibility and methods are discussed in the paper.

    The People's Republic of China gas recognized the importance of climate change concerns and has signed the Climate Change Convention, formulated at the United Nations Conference on Environment and Development. China is now beginning the process of developing an appropriate response strategy for climate change. Several projects have been initiated that deal with various aspects of global climate change. The Asian Development Bank is assisting the Chinese Government in this endeavor by providing technical assistance under an agreement signed in August 1992. The Bank selected a team of international consultants, coordinated by the East-West Center in Hawaii and including Argonne National Laboratory and Japanese scientists, to work closely with Chinese scientists to develop information that would contribute to a national response strategy. The Chinese research team is led by scientists from Tsinghua University and includes specialists from a number of research institutes and government agencies, all under the aegis of the State Science and Technology Commission. This paper presents results from the study concerning the interrelationship among economic growth, energy use, and carbon dioxide emissions in China, The study shows that, despite rapid improvements in energy efficiency and development of nonfossil-fuel energy sources, it will be difficult to prevent a two to three-fold increase in carbon dioxide emissions between 1990 and 2050

    The design of the first cold neutron triple-axis spectrometer at the China Advanced Research Reactor is presented. Based on the Monte Carlo simulations using neutron ray-tracing program McStas, the parameters of major neutron optics in this instrument are optimized. The neutron flux at sample position is estimated to be 5.6 ×107 n/cm2/s at neutron incident energy Ei=5 meV when the reactor operates normally at the designed 60 MW power. The performances of several neutron supermirror polarizing devices are compared and their critical parameters are optimized for this spectrometer. The polarization analysis will be realized with a flexible switch from the unpolarized experimental mode.

  13. Overview of Lead Based Reactor Design and R&D Status in China

    International Nuclear Information System (INIS)

    Liquid lead or lead based alloy is a potential candidate coolant for fast reactors and accelerator driven system (ADS) subcritical reactors because of its many unique nuclear, thermophysical and chemical attributes. The Chinese Academy of Sciences (CAS) launched an engineering project to develop ADS system and lead based reactors. A series of China lead based Reactors (named CLEAR) design, the lead based experimental loops (KYLIN series Pb–Bi loops and DRAGON series PbLi loops), a high intensified D-T neutron generator (HINEG) and structure material (CLAM) were developed by the Institute of Nuclear Energy Safety Technology. In this paper, the CLEAR design and R&D activities are presented. (author)

    Based on the modern economic theory and the characteristics of China's energy consumption, this paper analyzes the determinants of energy demand in China, builds up a China's energy demand model, and examines the long-run relationship between China's aggregate energy consumption and the main economic variables such as GDP by using the Johansen multivariate approach. It is found that there exists unique long-run relationship among the variables in the model over the sampling period. An error-correction model provides an appropriate framework for forecasting the short-run fluctuations in the aggregate demand of China.

  20. Moving, sensing intersectionality: a case study of Miss China Europe.

    Chow, Yiu Fai

    2011-01-01

    Every year, Miss China Europe, a transnational beauty pageant organized for the Chinese diaspora, is held in the Netherlands. The hypervisuality of Chinese diasporic women at the event stands in painful contrast to their everyday invisibility, whether in the Netherlands, China, or elsewhere in the world. Informed by intersectional and transnational feminist scholarship, this empirical study zooms in on one group of women, ethnic Chinese born and/or growing up in the Netherlands, to identify and recuperate their neglected lived experience in a particular historical-cultural context. It takes their own voices as central, hopefully to contribute to their visibility. It aims to provide an understanding of diasporic Chinese women as living in the dynamics not only of their multiple subordinations but also of their subjective consciousness, experienced autonomy, and agency. Drawing insights from the subjective accounts of both contestants and audiences of Miss China Europe, I suggest that one way to foreground marginalized women's agency is to understand their intersectionality in terms of movements and sensory experiences. On the one hand, while the contestants articulated a readiness to perform their modern and yet Chinese selves, they were making movements along two intersecting axes of inequality and power relations - Chineseness and Dutchness - precisely to negotiate their sense of inequality and power relations. On the other hand, among the audiences, two major topics - the blood issue (or whether Chineseness should be defined by ancestry) and the language problem (or whether Chineseness should be defined by the ability to speak Chinese) - were raised regularly, underscoring a complex viewing experience of seeing and hearing, of the tension between visual and audio identifications.

    Aerospace activity in near space (20-50 km) has become a research hotspot for aviation big countries worldwide. Solar radiation study, as the prerequisite to carry out aerospace activity, is facing the barrier of lacking of observation in near space layer. Ozone is the most important factor that affects radiation value in this layer. Based on ECMWF reanalysis data, this input key parameter and its horizontal, vertical and temporal characteristics are analyzedwith results showing obvious regional features in temporal-spatial distribution and varieties. With meteorological data and surface parameters, near space over China is divided into 5 parts. Key factors' value is confirmed over each division. With SBDART radiation transfer model, solar radiation and ultraviolet radiation simulation in near space are conducted separately. Results show that it is influenced by latitude, total ozone and its vertical distribution, radiation varies under complex rules. The average year and monthly solar radiation strengthens changes with latitude reduction, while annual range changes reversely. Air absorbing is related to latitude and land-sea contrast and shows different values and seasonal variations. The ultraviolet radiation over South China Sea reaches its maximum value and minimum annual range, as well as minimum monthly range with value strengthening in summer and weakening in winter. In other areas radiation increases in summer while weakens in winter, monthly range shows double peaks with higher value in spring and autumn, lower in summer and winter. Air absorption in ultraviolet radiation is influenced by multiple factors, vertical varieties over areas besides South China Sea enhance in summer time. The vertical changes of monthly ranges affected by air absorption show consistence in higher and lower layer in June and July, while in other months ranges are bigger in higher layer. PMID:27400492

    Full Text Available Abstract Background Hypertension is a serious public health problem in China and in other developing countries. Our aim is to conduct a systematic review of studies on the effectiveness of community interventions for hypertension management in China. Methods China National Knowledge Infrastructure, PubMed, and references of retrieved articles were searched to identify randomised or quasi-randomised controlled studies that evaluated community hypertension care in mainland China. One reviewer extracted and a second reviewer checked data from the included studies. Results We included 94 studies, 93 of which were in Chinese language, that evaluated the following interventions: health education, improved monitoring, family-support, self-management, healthcare management changes and training of providers. The study quality was generally poor, with high risk of biased outcome reporting and significant heterogeneity between studies. When reported, the vast majority of the included studies reported statistically significantly improved outcomes in the intervention group. By assuming zero treatment effects for missing outcomes, the weighted reduction in the intervention group was 6∙9 (95% CI: 4∙9 to 8∙9 mm Hg for systolic BP, and 3∙8 (95% CI: 2∙6 to 5∙0 mm Hg for diastolic BP. Exploratory subgroup analyses found no significant differences between different interventions. Conclusions After taking account of possible reporting biases, a wide range of community interventions for hypertension care remain effective. The findings have implications for China and other low and middle income countries facing similar challenges. Because of significant heterogeneity and high risk of bias in the available studies, further well designed studies should be conducted in China to provide high quality evidence to inform policy decisions on hypertension control.

    2006-01-01

    A large number of papers have been published and great efforts have been made in the recent 20 years by the Chinese oceanographic and meteorological scientists in the ocean-atmosphere interaction studies. The present paper is an overview of the major achievements made by Chinese scientists and their collaborators in studies of larger scale ocean-atmosphere interaction in the following oceans: the South China Sea, the Tropical Pacific, the Indian Ocean and the North Pacific. Many interesting phenomena and dynamic mechanisms have been discovered and studied in these papers. These achievements have improved our understanding of climate variability and have great implications in climate prediction, and thus are highly relevant to the ongoing international Climate Variability and Predictability (CLIVAR)efforts.

    China's economic boom in the last three decades has spurred increasing demand for transportation services and personal mobility. Consequently, vehicle population has grown rapidly since the early 1990s, especially in megacities such as Beijing, Guangzhou, and Tianjin. As a result, mobile sources have become more conspicuous contributors to urban air pollution in Chinese cities. Tianjin was our first focus city, and the study there took us about two years to complete. Building upon the experience and partnership generated through the Tianjin study, the research team carried out the Beijing study from fall 2007–fall 2008. Beijing was chosen to be our second focus city for several reasons: it has the largest local fleet and the highest percentage of the population owning vehicles among all Chinese cities, and it has suffered from severe air pollution, partially due to the ever-growing population of on-road vehicles.

    2007-01-01

    Full Text Available A global 3-D CTM model (OsloCTM2 has been used to study the tropospheric ozone distribution and budget over China. An area covering China and most of East Asia is chosen as the study area. Because of the very nevenly distributed emissions and population in China, the budget study has been done by splitting China into three sub-areas, according to the emission distribution and topography of the country. The model results indicate that in Western China (Area1 dynamic processes are dominating, and the contribution from photochemical ozone production is small. Central and South-East China (Area2 has on average 65% of the photochemical ozone production in China, since more than 80% of the anthropogenic emissions come from this area. Northeast China (Area3 is influenced both by natural and*9nthropogenic emissions. The seasonal variation of ozone budgets was calculated in order to understand how different processes vary with the seasons. The strongest influences of emissions from the continent over the West Pacific region are found in spring, because of the large eastward transport and increased photochemical activities. Most NOx is consumed close to the emission sources; therefore, only 4% of emitted NOx is transported out of China, whereas 70% of the emitted CO is exported. It is calculated that the average net chemical ozone production efficiency by NOx loss is 7.2 in China.

  8. Aladdin upgrade design study: shielding

    International Nuclear Information System (INIS)

    The object of this shielding is to examine all aspects of Aladdin operation to ensure that adequate shielding is provided to meet the design objectives. To do this, we will look at shielding necessary for radiation produced during the injection process, during normal loss of the stored beam and during accidental loss of the stored beam. It will therefore be necessary to specify shielding not only at the ring, but also along the injection line and the optical beam lines. We will also give special attention to the occupation of the accelerator Vault during injection as this may be a desirable design option. In effect, two shielding plans will be presented, permitting estimates of cost and space requirements for both

    Full Text Available The repair and regeneration of tissue is a well-discussed topic. Over the past 20 years, with the development of genetics, auxology, stem cell biology, and tissue engineering, tissue repair and regeneration have rapidly developed as emerging "Regenerative Medicine". Regenerative medicine has significant market demand in China. Based on national statistics, injury and poisoning patients rank third in afflictions in city hospitals (accounting for 9.13% and rank second in afflictions in county hospitals (accounting for 14.07%. Totally, approximately one hundred million patients suffered from traumatic, genetic and metabolic diseases in China and demand reparative and regenerative medical treatment each year. The Chinese government and its related departments have always attached great importance and support to the development of regenerative medicine, and the Chinese academic circle is involved in a very wide range of diseases and injuries including regenerative medical theory and technology. Stem cell biology, organ engineering and duplication, tissue engineering research and production have developed rapidly, and great portion of these studies have started to appear in applications, which have aroused extensive concerns in international professional circle. In the next 10 years, the Chinese regenerative medical system will be further improved, in both statute and rules, clinical translation will be further accelerated. Breakthroughs are expected in induced differentiation of stem cells and synchronous repair and regeneration of multiple organs, construction of major organs by tissue engineering, large-scale applications of tissue engineering products, and other aspects.

  11. Study on genetic coadaptability of wild quail populations in China

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Genetic coadaptability of wild Japanese quail, wild Common quail and Domestic quail populations in China was studied using 7 microsatellite DNA markers and Monte Carlo method to test genetic disequilibrium. The molecular effects of genetic coadaptability were analyzed through a new statistical model of neutral site. The results showed that genetic coadaptability dominated the genetic disequilibrium of the three quail populations, and totally 16.67%, 9.66% and 10.05% of non-allelic combinations were in the genetic disequilibrium in wild Japanese quail, wild Common quail and Domestic quail populations, respectively. Genetic coadaptability existed at almost all the tested sites. In the molecular point of view, genetic coadaptability plays an important role of keeping lots of polymorphisms in natural populations. Therefore, it is another key factor to the genetic disequilibrium in the population except for linkage. The results enrich the conceptions and connotations of genetic disequilibrium, and help us know more about genetic coadaptability and its effects, and lay a foundation of evaluation and protection of wild quail genetic resources in China.

  12. Designing an emissions trading scheme for China. An up-to-date climate policy assessment

    International Nuclear Information System (INIS)

    We assess recent Chinese climate policy proposals in a multi-region, multi-sector computable general equilibrium model with a Chinese carbon emissions trading scheme (ETS). When the emissions intensity per GDP in 2020 is required to be 45% lower than in 2005, the model simulations indicate that the climate policy-induced welfare loss in 2020, measured as the level of GDP and welfare in 2020 under climate policy relative to their level under business-as-usual (BAU) in the same year, is about 1%. The Chinese welfare loss in 2020 slightly increases in the Chinese rate of economic growth in 2020. When keeping the emissions target fixed at the 2020 level after 2020 in absolute terms, the welfare loss will reach about 2% in 2030. If China's annual economic growth rate is 0.5 percentage points higher (lower), the climate policy-induced welfare loss in 2030 will rise (decline) by about 0.5 percentage points. Full auctioning of carbon allowances results in very similar macroeconomic effects as free allocation, but full auctioning leads to higher reductions in output than free allocation for ETS sectors. Linking the Chinese to the European ETS and restricting the transfer volume to one third of the EU's reduction effort creates at best a small benefit for China, yet with smaller sectoral output reductions than auctioning. These results highlight the importance of designing the Chinese ETS wisely.

    Full Text Available Abstract Background The prevalence of childhood obesity among adolescents has been rapidly rising in Mainland China in recent decades, especially in urban and rich areas. There is an urgent need to develop effective interventions to prevent childhood obesity. Limited data regarding adolescent overweight prevention in China are available. Thus, we developed a school-based intervention with the aim of reducing excess body weight in children. This report described the study design. Methods/design We designed a cluster randomized controlled trial in 8 randomly selected urban primary schools between May 2010 and December 2013. Each school was randomly assigned to either the intervention or control group (four schools in each group. Participants were the 4th graders in each participating school. The multi-component program was implemented within the intervention group, while students in the control group followed their usual health and physical education curriculum with no additional intervention program. The intervention consisted of four components: a classroom curriculum, (including physical education and healthy diet education, b school environment support, c family involvement, and d fun programs/events. The primary study outcome was body composition, and secondary outcomes were behaviour and behavioural determinants. Discussion The intervention was designed with due consideration of Chinese cultural and familial tradition, social convention, and current primary education and exam system in Mainland China. We did our best to gain good support from educational authorities, school administrators, teachers and parents, and to integrate intervention components into schools’ regular academic programs. The results of and lesson learned from this study will help guide future school-based childhood obesity prevention programs in Mainland China.

    Three Devonian reefs (bioherms) from Yunnan and Guangxi, southern China, are studied in detail.Six microfacies types are differentiated. Colonial rugose corals (Columnaria, Disphyllum and Hexagonaria) at Qujing, tabulate corals (Alveolites) with massive stromatoporoids (Actinostroma and Stromatoporella) and sponges at Panxi, and massive stromatoporoids (Actinostroma, Trupetostroma and Stromatoporella) at Yangshuo belong to the most important reef builders. All the three reefs studied clearly reveal a successive evolution history. They developed on the carbonate banks, shallow carbonate platforms and platform margins in the Late Givetian and terminated in the Frasnian due to sea-level falls related to local uplifts of platforms. This coincides with a eustatic fall of relative sea level at the Frasnian/Famennian transition.

  16. Factors influencing integration of TB services in general hospitals in two regions of China: a qualitative study

    Directory of Open Access Journals (Sweden)

    Zou Guanyang

    2012-01-01

    Full Text Available Abstract Background In the majority of China, the Centre for Disease Control (CDC at the county level provides both clinical and public health care for TB cases, with hospitals and other health facilities referring suspected TB cases to the CDC. In recent years, an integrated model has emerged, where the CDC remains the basic management unit for TB control, while a general hospital is designated to provide clinical care for TB patients. This study aims to explore the factors that influence the integration of TB services in general hospitals and generate knowledge to aid the scale-up of integration of TB services in China. Methods This study adopted a qualitative approach using interviews from sites in East and West China. Analysis was conducted using a thematic framework approach. Results The more prosperous site in East China was more coordinated and thus had a better method of resource allocation and more patient-orientated service, compared with the poorer site in the West. The development of public health organizations appeared to influence how effectively integration occurred. An understanding from staff that hospitals had better capacity to treat TB patients than CDCs was a strong rationale for integration. However, the economic and political interests might act as a barrier to effective integration. Both sites shared the same challenges of attracting and retaining a skilled workforce for the TB services. The role of the health bureau was more directive in the Western site, while a more participatory and collaborative approach was adopted in the Eastern site. Conclusion The process of integration identifies similarities and differences between sites in more affluent East China and poorer West China. Integration of TB services in the hospitals needs to address the challenges of stakeholder motivations and resource allocation. Effective inter-organizational collaboration could help to improve the efficiency and quality of TB service. Key

    China has launched a variety of solar heating and cooling technology researches. Solar applications and building integration technology were found to be significant energy efficiency technologies. This paper investigated the passive house mode suited to the cold area of China. A comparative analysis of the evolution of design standards and differences of life style and house type in city and rural areas was performed. A comparative analysis of architectural design and energy demand between Germany and China was also performed. It was found that a wide gap exists between China and Germany on the building heat loss index. This paper also developed a passive house model for both city and rural environments. The two basic principles to consider in the design of a rural house are the needs of production and living; as well as adaptation to climatic conditions and resource and waste recycling.

    Inflation is always an important indicator to measure whether economy is stable and healthy. This paper provides a substantive survey of the research on the welfare cost of inflation, and uses the methods of consumer's surplus and neo-classical general equilibrium models respectively to estimate the welfare cost of inflation in China. The results show that high inflation will cause huge welfare cost in China, so keeping low inflation is beneficial to the entire economic welfare of China.

    VOR, the versatile optimal resolution chopper spectrometer, is designed to probe dynamic phenomena that are currently inaccessible for inelastic neutron scattering due to flux limitations. VOR is a short instrument by the standards of the European Spallation Source (ESS), 30.2m moderator to sample...... impossible both on a long chopper spectrometer at the ESS and with instruments at short pulsed sources. In comparison to current day chopper spectrometers, VOR can offer an order of magnitude improvement in flux for equivalent energy resolutions, ΔE/E = 1-3%. Further relaxing the energy resolution enables...... VOR to gain an extra order of magnitude in flux. In addition, VOR has been optimised for repetition rate multiplication (RRM) and is therefore able to measure, in a single ESS period, 6-14 incident wavelengths, across a wavelength band of 9 Å with a novel chopper configuration that transmits all...

  2. Design and manufacture of neutron time of flight spectrometer on China Advanced Research Reactor

    International Nuclear Information System (INIS)

    The cold or thermal neutron energy spectra on China Advanced Research Reactor (CARR) could be directly measured by neutron time of flight spectrometer. Spectrometer structure and selected parameters of its key components were introduced. The impact of chopper slit and flux limit slit on neutron counts and pulse width was analyzed. The formulas of neutron counts and pulse width which were dependent on neutron wavelength were acquired. According to neutron energy spectrum measurement requirement for high fluence rate neutron beam, low-sensitivity detector, detector flux limit slit and multi-channel scaler for data acquisition were selected. These would ensure that the count loss rate was less than 0.5%. Electronics framework of detection system was designed and the total resolution time was 22.15-29.46 μs. (authors)

  7. Designation and influence of household increasing block electricity tariffs in China

    International Nuclear Information System (INIS)

    Electricity is the guarantee of normal life, and the electricity price is widely concerned. As a developing country in the transition stage, abundant policy implications are included in the electricity price in China, thus, whether to adjust the resident electricity price is a dilemma for the government. However, the current single tariff system cannot cope with the complex social and environmental problems. A new price mechanism is indeed needed. This paper tries to design an increasing block tariffs system with the consideration of residential income and electricity consumption. The result indicates that the increasing block tariffs system with four-tier structure is more reasonable for China. Although the increasing block tariffs will result in the increase of electricity price, it is still acceptable and affordable. The increasing block tariffs will greatly improve the equity and efficiency, and promote the electricity saving and emissions reduction. Moreover, the power companies will increase tariffs revenue, which would use to the transmission networks investment in poor area. In order to the offset the limitations of the increasing block tariffs, the government should adopt some complementary measures. - Highlights: ► We design an increasing block tariffs for residential electricity consumption with four-tier structure. ► Both the equity and efficiency will be greatly improved. ► Electricity demand and CO2 emissions will reduce by 26.68 billion kWh and 14.11 million tons. ► Some measures should be taken as the complement to make the increasing block tariffs mechanism more efficient.

  8. Pb Isotope Study of Some Nonferrous Metallic Deposits in China

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Based on Pb-Pb isochron data of more than 40 Precambrian polymetallic deposits, the authors consider that there are four mineralization periods for the Precambrian copper deposits in China, and the major copper deposits were formed at about 1800 Ma; there are three mineralization periods for gold deposits formed from Archaean to Proterozoic. By studying hundreds of lead isotope data from some Mesozoic continental subvolcanic Cu and Ag polymetallic deposits and fine-disseminated gold deposits, the authors found that the calculation based on the lead single-stage evolution model or two-stage evolution model cannot give the true ore-forming ages but can provide more information about mineralization and material sources of the deposits.

    Full Text Available This study compares judgments of the fairness of economic actions among survey populations in Switzerland, and both student and non-student groups in the People's Republic of China, with the earlier Kahneman, Knetsch and Thaler (1986a surveys of Canadians. The findings suggest that fairness concerns matter among all of these groups, and the general patterns of what was and was not considered to be fair were similar. However, there were also some significant differences with the influence of fairness being weaker in the two Chinese samples than in the groups from the Western countries, with the influence being weakest in the Chinese student population for the wage related topics. On the whole, almost no significant gender differences were found in any of the new surveys.

    The scientific council of GANIL asked to perform a comparative study on the production methods based on gamma induced fission and rapid-neutron induced fission concerning the nature and the intensity of the neutron-rich products. The production rate expected should be around 10{sup 13} fissions per second. The study should include the implantation and the costs of the concerned accelerators. The scientific committee recommended also to study the possibility to re-inject the radioactive beams of SPIRAL-II in the cyclotrons available at GANIL in order to give access to an energy range from 1.7 to 100 MeV/nucleon. For that purpose, some study groups have been formed to evaluate the possibility of such a project in the different components: physics case, target-ion sources, drivers, post-acceleration and general infrastructure. The organization of the project study is given at the end of this report. The following report presents an overview of the study. Particularly the total costs have been assessed according to 3 options for the driver: 38.0*10{sup 6} euros for a 40 MeV deuteron linac, 18.7*10{sup 6} euros for a 45 MeV electron linac, and 29.1*10{sup 6} euros for a 80 MeV deuteron cyclotron.

    The process of bra design in the underwear industry is studied. Several important aspects of the process were identified: sizing, fabric selection, pattern development and grading, the use of CAD system, fitting and wear trials. Although the design process relies heavily on the expertise and experience of designers, the modern technology such as CAD can facilitate and optimize the design process, and the fitting process on life models is essential for the underwear design. The differences between domestic underwear companies and foreign major ones mainly lie at the lack of dress form specially used for underwear design, lack of CAD/CAM or not making full use of them, and most of all, lack of the professional bra designers or even skillful pattern designers. The prospects and future model of bra design process were also elaborated in this paper.

  14. Vehicle systems design optimization study

    Gilmour, J. L.

    1980-04-01

    The optimization of an electric vehicle layout requires a weight distribution in the range of 53/47 to 62/38 in order to assure dynamic handling characteristics comparable to current production internal combustion engine vehicles. It is possible to achieve this goal and also provide passenger and cargo space comparable to a selected current production sub-compact car either in a unique new design or by utilizing the production vehicle as a base. Necessary modification of the base vehicle can be accomplished without major modification of the structure or running gear. As long as batteries are as heavy and require as much space as they currently do, they must be divided into two packages - one at front under the hood and a second at the rear under the cargo area - in order to achieve the desired weight distribution. The weight distribution criteria requires the placement of batteries at the front of the vehicle even when the central tunnel is used for the location of some batteries. The optimum layout has a front motor and front wheel drive. This configuration provides the optimum vehicle dynamic handling characteristics and the maximum passsenger and cargo space for a given size vehicle.

  15. Study about sustainable scenario of nuclear fuel cycle in China

    International Nuclear Information System (INIS)

    As the economy grows, demand of electricity is growing in China. However, building more thermal power plant is obviously improper choice, due to the concern about running out of fossil fuel. According to National Program for Medium-to-Long-Term Scientific and Technological development published by Chinese government, 40 GWe nuclear power capacity will be achieved by 2020. Regarding to the speed of nuclear power plant construction in China now, recent report said that the nuclear capacity might rise to 60 GWe even 70 GWe by 2020 and the further substantial increase to 200 GWe by 2030. However, to guarantee sustainable supply of electricity by nuclear power, a large amount of uranium is needed. While, there is a limitation of uranium resources, too. A light water reactor (LWR) and fast breeder reactor (FBR) matched scenario should be considered to prevent the crisis of running out of nuclear fuel. The purpose of this study is to find out the best LWR-FBR matched scenario which can reduce uranium requirement efficiently. Four scenarios which consist of 10 cases are selected in this study. After simulating each case by two computer codes, it is clear that scenario 3-1 is the most efficient case in the aspect of saving natural uranium. Scenario 3-1 is a scenario that LWRs loaded with MOX fuel partially (MOX fuel is a kind of nuclear fuel which is a mixture of PuO2 and UO2) are introduced in 2020 and then they were replaced by Fast Breeder Reactors in 2050.

    Based on SPOT VEGETATION NDVI time-series data, multi-phase China's land use / land cover (LULC) data were extracted in this study, where land use degree method and land dynamic degree method were used to analyze the spatial and temporal change characteristics of China's LULC in the latest decade. Moreover, bookkeeping model was applied to analyze the response of China's carbon sink to LUCC. Research conclusions were achieved as follows. China's annual vegetation carbon sink was 0.22- 0.32PgC/year, equivalent to 26% -28% of China's industrial CO2 emissions over the same period. Dynamic changes in woodland and grassland led to carbon sink changed in 11.4-15.7TgC, and the increased carbon sink due to LUCC offset 1.3-1.4% of China's industrial CO2 emissions.

    Full Text Available Background Rapid economic growth in China in the past decades has been accompanied by dramatic changes in lifestyle and environmental exposures. The burdens of non-communicable diseases, such as cardiovascular diseases, diabetes and cancer, have also increased substantially. Methods/design We initiated a large prospective cohort–the Taizhou Longitudinal Study–in Taizhou (a medium-size city in China to explore the environmental and genetic risk factors for common non-communicable diseases. The sample size of the cohort will be at least 100,000 adults aged 30–80 years drawn from the general residents of the districts of Hailin, Gaogang, and Taixing (sample frame, 1.8 million of Taizhou. A three-stage stratified sampling method will be applied. Baseline investigations include interviewer-administered questionnaire, anthropometric measurements, and collection of buccal mucosal cells and blood specimens. DNA will be extracted for genetic studies and serum samples will be used for biochemical examinations. A follow-up survey will be conducted every three years to obtain information on disease occurrence and information on selected lifestyle exposures. Study participants will be followed-up indefinitely by using a chronic disease register system for morbidity and cause-specific mortality. Information on non-fatal events will be obtained for certain major categories of disease (e.g., cancer, stroke, myocardial infarction through established registry systems. Discussion The Taizhou Longitudinal Study will provide a good basis for exploring the roles of many important environmental factors (especially those concomitant with the economic transformation in China for common chronic diseases, solely or via interaction with genetic factors.

    Factors that caused slow growth in crop insurance participation and its ultimate failure in China were multi-faceted including high agricultural production risk, low participation rate, inadequate public awareness, high loss ratio, insufficient and interrupted government financial support. Thus, a clear and present need for data driven analyses and empirically-based risk management exists in China. In the present investigation, agricultural production data for two crops (corn, rice) in five counties in Jiangxi Province and Hunan province for design of a pilot crop insurance program in China. A crop insurance program was designed which (1) provides 75% coverage, (2) a 55% premium rate reduction for the farmer compared to catastrophic coverage most recently offered, and uses the currently approved governmental premium subsidy level. Thus a safety net for Chinese farmers that help maintain agricultural production at a level of self-sufficiency that costs less than half the current plans requires one change to the program: ≥80% of producers must participate in an area.

    This paper discusses the principles of study design and related methodologic issues in environmental epidemiology. Emphasis is given to studies aimed at evaluating causal hypotheses regarding exposures to suspected health hazards. Following background sections on the quantitative objectives and methods of population-based research, we present the major types of observational designs used in environmental epidemiology: first, the three basic designs involving the individual as the unit of analysis (i.e., cohort, cross-sectional, and case-control studies) and a brief discussion of genetic studies for assessing gene-environment interactions; second, various ecologic designs involving the group or region as the unit of analysis. Ecologic designs are given special emphasis in this paper because of our lack of resources or inability to accurately measure environmental exposures in large numbers of individuals. The paper concludes with a section highlighting current design issues in environmental epidemiology and several recommendations for future work. PMID:8206038

    The China Jintan Child Cohort study began in 2004 with 1656 pre-school participants and a research focus on studying the impact of environmental exposures, such as lead, on children's neurobehavioural outcomes. This population cohort now includes around 1000 of the original participants, who have been assessed three times over a period of 10 years. Since the original IJE cohort profile publication in 2010, participants have experienced a critical developmental transition from pre-school to school age and then adolescence. The study has also witnessed an increase in breadth and depth of data collection from the original aim of risk assessment. This cohort has added new directions to investigate the mechanisms and protective factors for the relationship between early health factors and child physical and mental health outcomes, with an emphasis on neurobehavioural consequences. The study now encompasses 11 domains, composed of repeated measures of the original variables and new domains of biomarkers, sleep, psychophysiology, neurocognition, personality, peer relationship, mindfulness and family dynamics. Depth of evaluation has increased from parent/teacher report to self/peer report and intergenerational family report. Consequently, the cohort has additional directions to include: (i) classmates of the original cohort participants for peer relationship assessment; and (ii) parental and grandparental measures to assess personality and dynamics within families. We welcome interest in our study and ask investigators to contact the corresponding author for additional information on data acquisition. PMID:26323725

    2013-01-01

    Summary:The importance of genetic factors in substance addiction has long been established. The rationale for this work is that understanding of the function of addiction genes and delineation of the key molecular pathways of these genes would enhance the development of novel therapeutic targets and biomarkers that could be used in the prevention and management of substance abuse. Over the past few years, there has been a substantial increase in the number of genetic studies conducted on addiction in China;these studies have primarily focused on heroin, alcohol, and nicotine dependence. Most studies of candidate genes have concentrated on the dopamine, opioid, and serotonin systems. A number of genes associated with substance abuse in Caucasians are also risk factors in Chinese, but several novel genes and genetic risk factors associated with substance abuse in Chinese subjects have also been identified. This paper reviews the genetic studies of substance abuse performed by Chinese researchers. Genotypes and alleles related to addictive behavior in Chinese individuals are discussed and the contributions of Chinese researchers to the international corpus of knowledge about the genetic understanding of substance abuse are described.

  18. Incentive mechanism design for the residential building energy efficiency improvement of heating zones in North China

    Starting with analyzing the investigation results by Ministry of Housing and Urban-Rural Development of China in 2005, more than half of the 10,236 participants are willing to improve the residential building energy efficiency and accept an additional cost of less than 10% of the total cost, the authors illustrate that incenting actions are necessary to improve building energy efficiency and build a central government-local government-market model. As a result of the model analysis, to pursue good execution effects brought by the incentive policies, the executors are required to distinguish the differences of incentive objects' economic activities and strongly respect the incenting on the energy conservation performance. A case study on the incentive policies of existing residential building energy efficiency improvement in heating zones in North China is given as well. Finally, it is strongly recommended to give the first priority to performance-based incentives so that to reduce the lazy behaviors of the incented objects and ensure the targets to be achieved.

    2002-01-01

    MANDELBROT enunciated the uncertainty of the length of a coastline in his paper" How long is the coastline of Britain?" published in " Science" in 1967. The fractal concept was presented for the first time in that paper and has been applied to many fields ever since. According to the fractal theory and conditions of fractal research of coastline, the controls of faults and biologic function on the fractal character of coastline are preliminarily discussed on the basis of GIS in this paper . Finally, some significant conclusions are drawn: 1) the faults control the basic trends of coastlines of two study areas;2) the fractal dimension of coastline of Taiwan is smaller than that of Changle- Lufeng, because the faults of Taiwan more intensely control the trend and fractal dimension of the coastline;3) the larger the fractal dimension of the faults or the major faults, the more the controlling effect of them on the trend and fractal dimension of coastline; 4) the larger fractal dimension of the coastline of Changle- Lufeng indicates that the biologic function intensely shapes the coastline. In a word, the controls of faults and biologic function on the fractal character of coastline are discussed with a case study of China in this paper, it can be seen that faults and biologic function both have influence over the trend and fractal dimension of coastline, the fractal mechanism of coastline of two study areas may be so.

    It is more and more acknowledged that land-use/cover dynamic change has become a key subject urgently to be dealt with in the study of global environmental change. Supported by the Landsat TM digital images, spatial patterns and temporal variation of land-use change during 1995-2000 are studied in the paper. According to the land-use dynamic degree model, supported by the 1km GRID data of land-use change and the comprehensive characters of physical, economic and social features, a dynamic regionalization of land-use change is designed to disclose the spatial pattern of land-use change processes. Generally speaking, in the traditional agricultural zones, e.g., Huang-Huai-Hai Plains, Yangtze River Delta and Sichuan Basin, the built-up and residential areas occupy a great proportion of arable land, and in the interlock area of farming and pasturing of northern China and the oases agricultural zones, the reclamation of arable land is conspicuously driven by changes of production conditions, economic benefits and climatic conditions. The implementation of "returning arable land into woodland or grassland" policies has won initial success in some areas, but it is too early to say that the trend of deforestation has been effectively reversed across China. In this paper, the division of dynamic regionalization of land-use change is designed, for the sake of revealing the temporal and spatial features of land-use change and laying the foundation for the study of regional scale land-use changes. Moreover, an integrated study, including studies of spatial pattern and temporal process of land-use change, is carried out in this paper, which is an interesting try on the comparative studies of spatial pattern on change process and the change process of spatial pattern of land-use change.

  6. Uncovering opportunity of low-carbon city promotion with industrial system innovation: Case study on industrial symbiosis projects in China

    International Nuclear Information System (INIS)

    There is a dilemma for rapid industrializing China to balance economic growth and low carbonization. Industrial symbiosis (IS) provides a system innovation to utilize the industry to fight climate change and pursue sustainable urban development, while few attentions are paid in literatures. Under this circumstance, this study reviews the low-carbon city practice in China and conducts a case study to calculate the CO2 emissions reduction potential under promoting IS projects in two cities of China, named Jinan and Liuzhou. With the real national project in Jinan as advanced example, new scenarios related to IS are designed for Liuzhou, including comprehensive energy network, waste plastics recycling, scrap tires recycling and flying ash recycling. The material/waste and energy exchange is quantified in the IS network, as well as the related environmental benefit. The material/energy exchange is over 10 million ton and 20 thousands tce in Jinan's case, and 2.5 million ton and 45 thousand tce in Liuzhou's case. Results highlight that IS could effectively reduce CO2 emissions. The total reduction potential amounts to 3944.05 thousands tCO2/year and 2347.88 thousands tCO2/year in Jinan and Liuzhou. Finally, policy implications on the ever-improvement of industrial symbiosis and China's sustainable urban development are proposed and discussed. - Highlights: • Investigate two real industrial symbiosis projects in Jinan and Liuzhou of China. • Quantify the material exchange and the CO2 reduction potential of the IS network. • CO2 reduction potential is 3944.05 and 2347.88 ktCO2/year in Jinan and Liuzhou. • In current China, IS is main in term of material symbiosis. • How to coordinate IS and low-carbon city is discussed

  7. Study on China's low carbon development in an Economy-Energy-Electricity-Environment framework

    International Nuclear Information System (INIS)

    Emissions mitigation is a major challenge for China's sustainable development. We summarize China's successful experiences on energy efficiency in past 30 years as the contributions of Energy Usage Management and Integrated Resource Strategic Planning, which are essential for low-carbon economy. In an Economy-Energy-Electricity-Environment (E4) framework, the paper studies the low-carbon development of China and gives an outlook of China's economy growth, energy-electricity demand, renewable power generation and energy conservation and emissions mitigation until 2030. A business-as-usual scenario is projected as baseline for comparison while low carbon energy and electricity development path is studied. It is defined as low carbon energy/electricity when an economy body manages to realize its potential economic growth fueled by less energy/electricity consumption, which can be characterized by indexes of energy/electricity intensity and emissions per-unit of energy consumption (electricity generation). Results show that, with EUM, China, could save energy by 4.38 billion ton oil equivalences (toes) and reduce CO2 emission by 16.55 billion tons; with IRSP, China, could save energy by 1.5 Btoes and reduce CO2 emission by 5.7 Btons, during 2010-2030. To realize the massive potential, China has to reshape its economic structure and rely much on technology innovation in the future. - Research highlights: → In an E4 framework China's low-carbon development is compared with BAU scenario. → Low carbon energy/electricity and their related measuring indexes are discussed. → China's successful experiences on energy efficiency are summarized as EUM and IRSP. → With them China could save energy by 5.8 Btoe and reduce CO2 by 22.2 Bton until 2030. → China must restructure its economy and rely on technology innovation for them.

    The depth of the geological repository of high level radioactive waste (HLW) in China is discussed. At least 500 m below the ground surface is preliminarily determined for the geological repository with granite formation, and no less than 300 m, 300∼500 m might be the most suitable depth, for the repository with argillaceous rock. The access type of the repository is analyzed. It is advised that both shaft and ramp should be considered in the conceptual design. Function zones of the repository are proposed, including waste disposal zone, connection drifts, underground plants, maintenance area, etc. The disposal spacing is developed based on the thermal calculations, and the required area of the repository is estimated. The conceptual design of the underground general layout of the repository is proposed based on the research work mentioned above, which plays an important role in the conceptual design of the geological repository in China and provides the basis for the more comprehensive design and analysis in the near future. With the development of the geological repository of HLW in China, more factors and the uncertainty should be taken into consideration and perform more detailed design and calculations. (authors)

  19. Structural Evolution of Household Energy Consumption: A China Study

    Directory of Open Access Journals (Sweden)

    Qingsong Wang

    2015-04-01

    Full Text Available Sustainable energy production and consumption is one of the issues for the sustainable development strategy in China. As China’s economic development paradigm shifts, household energy consumption (HEC has become a focus of achieving national goals of energy efficiency and greenhouse gas reduction. The information entropy model and LMDI model were employed in this study in order to analyse the structural evolution of HEC, as well as its associated critical factors. The results indicate that the information entropy of HEC increased gradually, and coal will be reduced by clean energies, such as natural gas and liquefied petroleum gas. The information entropy tends to stabilize and converge due to rapid urbanization. Therefore, from the perspective of environmental protection and natural resource conservation, the structure of household energy consumption will be optimized. This study revealed that residents’ income level is one of the most critical factors for the increase of energy consumption, while the energy intensity is the only driving force for the reduction of HEC. The accumulated contribution of these two factors to the HEC is 240.53% and −161.75%, respectively. It is imperative to improve the energy efficiency in the residential sector. Recommendations are provided to improve the energy efficiency-related technologies, as well as the standards for the sustainable energy strategy.

    Regional innovation system (RIS) is the new research field of modern economic geography in the age of knowledge economy. Based on the researches of regional economic geography, the authors of the paper consider RIS as the integrated and interactive systems with innovation milieu, elements, units, structure and functions. Five aspects of evaluation indicators including innovation input scale and output scale, innovation milieu transition, innovation in-ner operation, as well as innovation outer impact are worked out for final indicators of RIS scale and quality. Accord-ing to different RIS situations, three patterns of independent, imitative and cooperative development are put forward for choosing. At the latter part of the paper, we select 12 provincial regions (including three municipalities and one au-tonomous region) of China for empirical study. The results show that there exists great difference among each region from the aspects of innovation scale and quality mainly owning to the diversification of RIS social and economic mi-lieu, the major innovative units of enterprises, universities and R&D institutes. Finally, the paper points out the innova-tion development decisions for each region.

    2009-01-01

    Landfill gas (LFG) utilization which means a synergy between environmental protection and bioenergy recovery was investigated in this study. Pressure swing adsorption technology was used in LFG purification, and laboratory experiment, pilot-scale test, and on-site demon-stration were carried out in Shenzhen, China. In the laboratory experiment, A-type carbon molecular sieve was selected as the adsorbent by comparison of several other adsorbents. The oPtimal adsorption pressure and adsorp-tion time were 0.25 MPa and 2 min, respectively, under which the product generation rate was 4.5 m3/h and the methane concentration was above 90%. The process and optimization of the pilot-scale test were also reported in the paper. The product gas was of high quality compared with the National Standard of Compressed Natural Gas as Vehicle Fuel (GB 18047-2000), when the air concentration in feed gas was under 10.96%. The demonstration project was composed of a collection system, production system,and utilization system. The drive performance, environ-mental protection performance, and economic feasibility of the product gas -- as alternative fuel in passenger car,truck, and bulldozer-were tested, showing the feasibility technology for LFG utilization.

  18. Study on 220Rn equilibrium factor in China traditional dwellings

    International Nuclear Information System (INIS)

    The spatial distribution and seasonal variation of 220Rn concentration (CTn) and its progeny concentration (Cp,Tn) in China traditional dwellings constructed with soil were studied. The results show that the spatial distribution of CTn appears a significant concentration gradient, and decreases exponentially from the distance of source (bare walls or ground), while there is a good linearity and repeatability. The seasonal variation of CTn displays maximum value in autumn and minimum value in winter. The seasonal variation of Cp,Tn comparing with CTn and Cp,Rn is similar, and its spatial variation can be ignored. Therefore, fixing the distance distance of 220Rn form source, there is a definite relationship between CTn and Cp,Tn. 220Rn equilibrium factors FTn respectively are 0.003±0.001 and 0.017±0.014 at the distances of 2.5 cm and 20 cm from wall. The Cp,Tn results of actual measurement in traditional houses are in good agreement with the calculated values by using FTn. The measurement to 220Rn gas is more easily achieved comparing with 220Rn progenies. The introduction of FTn provides a simple and reliable method for assessment of 220Rn exposure. (authors)

  1. Systemic Design: Two Canadian Case Studies

    Directory of Open Access Journals (Sweden)

    Alex Ryan

    2014-12-01

    Full Text Available This paper introduces two novel applications of systemic design to facilitate a comparison of alternative methodologies that integrate systems thinking and design. In the first case study, systemic design helped the Procurement Department at the University of Toronto re-envision how public policy is implemented and how value is created in the broader university purchasing ecosystem. This resulted in an estimated $1.5 million in savings in the first year, and a rise in user retention rates from 40% to 99%. In the second case study, systemic design helped the clean energy and natural resources group within the Government of Alberta to design a more efficient and effective resource management system and shift the way that natural resource departments work together. This resulted in the formation of a standing systemic design team and contributed to the creation of an integrated resource management system. A comparative analysis of the two projects identifies a shared set of core principles for systemic design as well as areas of differentiation that reveal potential for learning across methodologies. Together, these case studies demonstrate the complementarity of systems thinking and design thinking, and show how they may be integrated to guide positive change within complex sociotechnical systems.

  9. Progress in conceptual study of China fusion-based hydrogen production reactor

    International Nuclear Information System (INIS)

    Full text: As one of the series of fusion system design concepts developed by the FDS Team of China, Fusion-based hydrogen production reactor (FDS-III) is designated to exploit the fusion energy advanced application for the production of hydrogen, and satisfy fusion development strategy in China. FDS-III is a cost competitive reactor concept with a fusion power of ∼2.5GW, whose parameters are selected based on the progress in recent magnetic confinement fusion. The neutron wall load of 3.5∼4MW/m2 and the surface heat flux of ∼0.8MW/m2 are considered. for high effective energy conversion. An innovative high temperature liquid lithium-lead blanket (HTL) concept based on the Reduced Activation Ferritic-Martensitic steel (RAFM) as structural material is proposed as an option of the blanket concepts for FDS-III. The 'multilayer flow channel inserts (MFCIs)' have been adopted in the LiPb channels to attain high outlet temperature about 1000 deg C to satisfy the need of high efficiency production of hydrogen. The blanket combines advantage of the banana segment and large module to improve maintenance efficiency and reduce effect of electric magnetic force. The maintenance scheme considered is based on the removal of blanket segment and divertor cassettes through the big equatorial ports. In order to achieve a high energy conversion system, a carbon dioxide Brayton cycle is adopted which permit a high thermal efficiency. Preliminary cost analysis show FDS-III is a competition fusion reaction for hydrogen production. This paper gives the preliminary design and study of FDS-III. (author)

    2005-01-01

    Based on B2 climate change scenario produced by PRECIS (providing regional climates for impacts studies), which was developed by the UK Hadley Center, and the wheat yield data outputted by CERES-wheat model, the sensitivity and vulnerability of wheat production to the future climate change in China were studied through analyzing the yield variation using the GIS (geographical information system) techniques. Results showed that, by the 2070s, there will be three negative sensitive areas of rain-fed wheat, i.e., northeastern China, the region of the middle and lower reaches of the Yangtze River, and part of the Loess Plateau. Irrigated wheat is generally sensitive to the future climate change for most areas of China, with a lower sensitive degree and a distribution of sensitive areas similar to the rain-fed wheat. For the irrigated wheat, northeast and northwest of China are strongly negative sensitive, while the middle and lower reaches of the Yangtze River, the coastal areas of southern China and the southwest of China, are moderately negative sensitive to the climate change. With the appropriate adaptation to the climate change, the rain-fed wheat in most regions of China will not be vulnerable and even has a yield increase, while the irrigated wheat will still have a larger vulnerable area (occupying about 2/3 of its total area in China), with the highly vulnerable regions distributed in northeastern China and northwestern China, and the medium and light vulnerable areas distributed along the middle and lower reaches of the Yangtze River,Yunnan and Guizhou provinces.

    2015-08-01

    Full Text Available In order to push forward the development of CFRP cable-stayed bridge and accumulate experiences, the study on the application of the first cable-stayed bridge with CFRP cables in China was carried out. The design essentials of main components of the bridge were introduced and its integral performances, including static properties, dynamic properties and seismic response were analyzed using finite element method. A new bond-type anchorage was developed and the processes of fabricating and installing CFRP cables were elaborated. Based on the results of construction simulation, a tension scheme for bridge was propound. During constructing, the stresses and displacement of girder and pylon, as well as the forces and stresses of cables, were tested. The results indicate that all sections of the bridge could meet the requirements of the ultimate bearing capacity and normal service; the performance of the anchorage is good and the stresses in each cable system are similar; the tested values accord well with the calculated values. Further, creep deformation of the resin in anchorages under service load is not obvious. All these results demonstrate that the first application of CFRP cables in the cable-stayed bridge in China is successful.

    2014-03-01

    The last two decades have witnessed the gradual implementation of integrated science curriculum at the junior secondary level in China. However, in most provinces of China, the implementation is not as successful as expected. Challenges were reported, yet without fine-grained investigation, with respect to science teachers' instruction on integrated science. In this study, we aim to detect major problems by investigating the instruction of integrated science at the secondary level. Classroom observation focused on the teacher and student verbal behavior, teachers' competency of instructional organization, their presentation of instructional content, and the organization of learning activities. Findings revealed that students were provided with limited opportunities for participating and engaging in learning as science teachers were dominant in classroom talk. Teachers emphasized on the integration of knowledge within one subject (within-subject knowledge), but not the integration of knowledge between subjects (cross-subject knowledge), resulting in the unsuccessful instruction of the integrative content. What is more, teachers were inadequately competent in designing and delivering science, technology and society content, scientific inquiry and scientific experiments, which also affected the quality of instruction on integrated science.

    2002-01-01

    In the mid-1990s, we established the national operative dynamic information serving systems on natural resources and environment. During building the land-use/land-cover change (LUCC)database for the mid-1990s, 520 scenes of remotely sensed images of Landsat Thematic Mapper (TM) were interpreted into land-use/land-cover categories at scale of 1:100,000 under overall digital software environment after being geo-referenced and ortho-rectified. The vector map of land-use/land-cover in China at the scale of 1:100,000 was recently converted into a 1-km raster database that captures all ofthe high-resolution land-use information by calculating area percentage for each kind of land use category within every cell. Being designed as an operative dynamic information serving system,monitoring the change in land-use/land-cover at national level was executed. We have completed the updating of LUCC database by comparing the TM data in the mid-1990s with new data sources received during 1999-2000 and 1989-1990. The LUCC database has supported greatly the national LUCC research program in China and some relative studies are incompletely reviewed in this paper.

  3. Atmospheric organic nitrogen deposition: Analysis of nationwide data and a case study in Northeast China

    International Nuclear Information System (INIS)

    The origin of atmospheric dissolved organic nitrogen (DON) deposition is not very clear at present. Across China, the DON deposition was substantially larger than that of world and Europe, and we found significant positive correlation between contribution of DON and the deposition flux with pristine site data lying in outlier, possibly reflecting the acute air quality problems in China. For a case study in Northeast China, we revealed the deposited DON was mainly derived from intensive agricultural activities rather than the natural sources by analyzing the compiled dataset across China and correlating DON flux with NH4+–N and NO3−–N. Crop pollens and combustion of fossil fuels for heating probably contributed to summer and autumn DON flux respectively. Overall, in Northeast China, DON deposition could exert important roles in agro-ecosystem nutrient management and carbon sequestration of natural ecosystems; nationally, it was suggested to found rational network for monitoring DON deposition. -- Highlights: •Contribution and deposition flux of DON across China was positively correlated. •Deposited DON was more influenced by human in China than across the world and Europe. •DON of a farmland in Northeast China was mainly derived from agricultural activities. •Crop pollen and combustion of fossil fuels contributed to summer and autumn DON. •Deposited DON should not be neglected when evaluating its ecological impacts. -- Synthesis of DON deposition across China implied regional importance of anthropogenic sources, and an observation in Northeast China suggested the ecological significances of the DON flux should be considered

    The rapid urbanization of China has increased pressure on its environmental and ecological well being. In this study, the temporal and spatial profiles of China's carbon dioxide emissions are analyzed by taking heterogeneities into account based on an integration of the extended stochastic impacts using a geographically and temporally weighted regression model on population, affluence, and technology. Population size, urbanization rate, GDP per capita, energy intensity, industrial structure, energy consumption pattern, energy prices, and economy openness are identified as the key driving factors of regional carbon dioxide emissions and examined through the empirical data for 30 provinces during 2006-2010. The results show the driving factors and their spillover effects have distinct spatial and temporal heterogeneities. Most of the estimated time and space coefficients are consistent with expectation. According to the results of this study, the heterogeneous spatial and temporal effects should be taken into account when designing policies to achieve the goals of carbon dioxide emissions reduction in different regions.

  15. Advanced SFR concept design studies at KAERI

    International Nuclear Information System (INIS)

    Full text: Advanced SFR design concepts have been proposed and evaluated against the design requirements to satisfy the Gen IV technology goals. Two types of conceptual core designs, Breakeven and TRU burner cores were developed. Breakeven core is 1,200 MWe and does not have blankets to enhance the proliferation resistance. According to the current study, TRU burning rate increases linearly with the rated core powers from 600 MWe to 1,200 MWe. Considering 1) the realistic size of an SFR demonstration reactor for the long-term R and D plan with the goal of a demonstration SFR construction by 2028, and 2) the availability of a KALIMER-600 reactor system design that was developed in the last R and D phase, a TRU burner of 600 MWe was selected. The heat transport system of Advanced SFR was designed to be a pool type to enhance system safety through slow system transients, where primary sodium is contained in a reactor vessel. The heat transport system is composed of Primary Heat Transport System (PHTS), Intermediate Heat Transport System (IHTS), Steam Generating System (SGS) and Residual Heat Removal System (RHRS). The heat transport system was established through trade studies in order to enhance the safety and to improve the economics and performance of the KALIMER-600 design. Trade studies were performed for the number of IHTS loops, the number of PHTS pumps, Steam Generator (SG) design concepts, energy conversion system concepts, cover gas operation methods, and an improved concept of safety-graded passive decay heat removal system. From the study, the heat transport system of Advanced SFR has design features such as two IHTS loops, a Rankine cycle energy conversion system, two double-wall straight tube type SGs, and a passive decay heat removal system. In order to secure the economic competitiveness of an SFR, several concepts were implemented in the mechanical structural design without losing the reactor safety level. The material of reactor vessel and internal

  4. Conceptual study of advanced PWR core design

    International Nuclear Information System (INIS)

    The purpose of this project is for developing and verifying the core design concepts with enhanced safety and economy, and associated methodologies for core analyses. From the study of the sate-of-art of foreign advanced reactor cores, we developed core concepts such as soluble boron free, high convertible and enhanced safety core loaded semi-tight lattice hexagonal fuel assemblies. To analyze this hexagonal core, we have developed and verified some neutronic and T/H analysis methodologies. HELIOS code was adopted as the assembly code and HEXFEM code was developed for hexagonal core analysis. Based on experimental data in hexagonal lattices and the COBRA-IV-I code, we developed a thermal-hydraulic analysis code for hexagonal lattices. Using the core analysis code systems developed in this project, we designed a 600 MWe core and studied the feasibility of the core concepts. Two additional scopes were performed in this project : study on the operational strategies of soluble boron free core and conceptual design of large scale passive core. By using the axial BP zoning concept and suitable design of control rods, this project showed that it was possible to design a soluble boron free core in 600 MWe PWR. The results of large scale core design showed that passive concepts and daily load follow operation could be practiced. (author). 15 refs., 52 tabs., 101 figs

    Background "Vision 2020" was initiated in 1999 and many relevant activities are ongoing, but little information is available on what it has achieved and what constraints it faces. It is not yet clear if funding is the most important constraint. Nepal is one of the underdeveloped countries, but an advanced country in preventing avoidable blindness.The aim of this study was to compare the situation in China and in Nepal in prevention of avoidable blindness.Methods Data from literature review and a field visit were combined. All statistical analyses were carried out with SPSS Version 11.5. The chi-square test was used for comparisons involving categorical variables.Results The blindness rate is higher in Nepal than that in China (P<0.05). The average number of cataract operations performed by one ophthalmologist is much lower in China than in Nepal. The cataract surgical rate (CSR) is much lower in China than in Nepal (P<0.001). High cost of the surgery and inadequate qualifications of human resources were found in China. Cataract surgical outcome in China compared well with international standards.Conclusions Progress towards the "Vision 2020" target in China is much slower than that in Nepal.

  15. Inter-provincial clean development mechanism in China: A case study of the solar PV sector

    International Nuclear Information System (INIS)

    With ever growing urgency, climate change mitigation is fast becoming a priority for China. A successful policy of implementing and expanding sustainable development and the use of renewable energy is therefore vital. As well as long-term and near-term targets for installed capacity of renewable energy, in its 12th five-year plan, China has created strict and ambitious carbon intensity targets for each province. This study proposes an inter-provincial clean development mechanism to assist in meeting these targets. This mechanism will create potential co-benefits of assisting in sustainable development in lesser developed provinces, increasing local air quality and supporting the growth of China's renewable energy sector. This paper also highlights the potential that this inter-provincial clean development mechanism has in accelerating the growth of the domestic solar photovoltaics (PV) sector, for which the market in China is still in its infancy. - Highlights: ► We recognise the necessity for each province in China to reduce its GHG emissions. ► We assess the potential of a national scale a CDM style mechanism for China. ► We consider the effect that the national CDM could have on solar PV in China

    Full Text Available Background: Despite having one of the highest mortality rates of all cancers, the risk factors of pancreatic cancer remain unclear. We assessed risk factors of pancreatic cancer in China. Methods: A case-control study design was conducted using data from four hospital-based cancer registries (Henan Provincial Cancer Hospital, Beijing Cancer Hospital, Hebei Provincial Cancer Hospital, and Cancer Hospital of Chinese Academy of Medical Sciences. Controls were equally matched and selected from family members of non-pancreatic cancer patients in the same hospitals. Face-to-face interviews were conducted by trained staff using questionnaires. Conditional logistic regression models were used to assess odd ratios (ORs and 95% confident intervals (CIs. Results: Among 646 recruited participants, 323 were pancreatic cancer patients and 323 were controls. Multivariate logistic analysis suggested that pancreatic cancer family history (adjusted OR 1.23; 95% CI, 1.11–3.70, obesity (adjusted OR 1.77; 95% CI, 1.22–2.57, diabetes (adjusted OR 2.96; 95% CI, 1.48–5.92 and smoking (adjusted OR 1.78; 95% CI, 1.02–3.10 were risk factors for pancreatic cancer, but that drinking tea (adjusted OR 0.49; 95% CI, 0.25–0.84 was associated with reduced risk of pancreatic cancer. Conclusions: Cigarette smoking, family history, obesity, and diabetes are risk factors of pancreatic cancer, which is important information for designing early intervention and preventive strategies for pancreatic cancer and may be beneficial to pancreatic cancer control in China.

    2013-02-01

    According to institutional theorists, the forms and business models of corporation are mainly shaped by factors such as politics, regulations, social norms and cultures. This paper examines how the International Financial Reporting Standards (IFRS) and institutional environment influence the accounting quality, in response to the threat of political extraction in China. We took mainland China as an example instead in our study, following the accounting quality definition of Barth et al. [2], we found that the developments of Chinese government performance audit are conspicuously different by region; to reflect such differences, we elaborated our research by dividing mainland China into 31 categories (provinces or cities). We set 2003-2010 as the time horizon for this study. After testing the Regression model, our empirical research achieved two conclusions: 1) IFRS adoption in China should significantly improve the accounting quality, and 2) IFRS and institutional environment should synthetically influence the quality of accounting as well.

Some clinical trials conducted in Western countries have demonstrated that CRT could improve CHF patients’ symptoms and reduce mortality. However, due to the differences in economic and social conditions as well as inconsistencies in CHF etiologies between China and Western countries, there is an urgent need to conduct a large-scale CRT clinical study in Chinese patients with CHF. The ADOPT Trial (Assessment of Efficacies of Cardiac Resynchronization Therapies (CRT-P/D for Heart Failure Patients in China is designed to observe whether CRT can further improve syptoms and reduce mortality in Chinese patients in addition to optimal pharmalogical therapy.Methods: The ADOPT study is a prospective, nested, case-controlled, open-label clinical trial. About 40 centers across China participate in this study with a planned 800 Chinese cases to be enrolled. All patients will receive optimal medical treatment. Patients who have successful CRT-P/D implant will be assigned to the CRT group. According to the baseline evaluation, matched cases will be selected from the enrolled optimal pharmaceutical therapy alone group (Group for Selection. After successful match, the cases in Group for Selection enter into follow-up and become the control group. The unmatched cases in the Group for Selection will be removed. If patients

    Currently, next-generation sequencing studies aim to identify rare and low-frequency variation that may contribute to disease. For a given effect size, as the allele frequency decreases, the power to detect genes or variants of interest also decreases. Although many methods have been proposed for the analysis of such data, study design and analytic issues still persist in data interpretation. In this study we present sequencing data for ABCA1 that has known rare variants associated with high-density lipoprotein cholesterol (HDL-C). We contrast empirical findings from two study designs: a phenotypic extreme sample and a population-based random sample. We found differing strengths of association with HDL-C across the two study designs (P=0.0006 with n=701 phenotypic extremes vs P=0.03 with n=1600 randomly sampled individuals). To explore this apparent difference in evidence for association, we performed a simulation study focused on the impact of phenotypic selection on power. We demonstrate that the power gain for an extreme phenotypic selection study design is much greater in rare variant studies than for studies of common variants. Our study confirms that studying phenotypic extremes is critical in rare variant studies because it boosts power in two ways: the typical increases from extreme sampling and increasing the proportion of relevant functional variants ascertained and thereby tested for association. Furthermore, we show that when combining statistical evidence through meta-analysis from an extreme-selected sample and a second separate population-based random sample, power is lower when a traditional sample size weighting is used compared with weighting by the noncentrality parameter.

    2015-01-01

    Full Text Available This paper focuses on the impacts of renewable energy policy on a large-scale power generation system, including thermal power, hydropower, and wind power generation. As one of the most important clean energy, wind energy has been rapidly developed in the world. But in recent years there is a serious waste of wind power equipment and investment in China leading to many problems in the industry from wind power planning to its integration. One way overcoming the difficulty is to analyze the influence of wind power policy on a generation system. This paper builds a system dynamics (SD model of energy generation to simulate the results of wind energy generation policies based on a complex system. And scenario analysis method is used to compare the effectiveness and efficiency of these policies. The case study shows that the combinations of lower portfolio goal and higher benchmark price and those of higher portfolio goal and lower benchmark price have large differences in both effectiveness and efficiency. On the other hand, the combinations of uniformly lower or higher portfolio goal and benchmark price have similar efficiency, but different effectiveness. Finally, an optimal policy combination can be chosen on the basis of policy analysis in the large-scale power system.

    This study was designed to investigate the current prevalence of hyperhomocysteinemia (Hhcy) and its association with hypertension in rural adults of Northeast China. A cross-sectional study was performed in subjects aged⩾35 years in a general Chinese population. Demographic data, laboratory examination of traditional cardiovascular risk factors and self-reported information on lifestyle factors, such as physical activities, current smoking and drinking status, dietary habits and familial factors were collected by trained personnel. A total of 7130 participants (3317 men and 3813 women) were included in this study and the mean Hhcy level of the whole population was 17.39±12.34 mmol l(-1), which was 20.99±14.83 mmol l(-1) in males and 14.19±8.51 mmol l(-1) in females, respectively. Prevalence of Hhcy in total population was 41.3%. Stratified by gender, the prevalence of Hhcy was higher in males than in females (59.0 vs 25.8%, P<0.05). After adjustment for conventional risk factors including age, salt intake, smoking, body mass index, diabetes, dyslipidemia, activity time and family history, multiple logistic regression analysis showed that Hhcy was independently associated with the risk of hypertension in males (odds ratio (OR)=1.501, 95% confidence interval (CI): 1.012-2.227; P<0.001), but not in females in this population (OR=1.182; 95% CI, 0.993-1.407; P=0.060). In conclusion, a high prevalence of Hhcy in the general adult population of rural northeast China was detected and Hhcy may be a risk factor for hypertension, particularly in males. PMID:26155996

    The coal resource has an important role in the energy development strategy in China. Because the coal resources are a kind of non-renewable resources, a kind of exhausting resource, which is limited in quantity, and the exploitation of the recourses are not economized now, so how to realize the sustainable development for coal resource in China is very important. In this paper, two parts were researched to optimize the coal mining. In order to optimize the mining order of different mining areas, the fuzzy logic evaluation was used to build the evaluation system. The economic control theory model was built to realize the proper period to explore the coal recourses for the same mining areas.

    Attributions of floods/cooler along the Yangtze River Valley and droughts/warmer in North China for the last 25 years have been reviewed in this paper. Both natural climate variability and human activities are considered. Some stronger evidences contributed to the natural climate variability, such as decadal and interdecadal variabilities of East Asian summer monsoon, the periodicities and transitions of rainfall and temperature changes in China, abrupt climate change, NAO, AO, AAO, ENSO, and snow cover. The signals produced by the human activities such as greenhouse gases and "brown clouds" likely play the role for the patterns. But the physical feedbacks and mechanisms still keep ambiguous and vague. More researches should be carried out in future to solve this issue.

    This paper analyzes the first differences of the annual means (annual rate) for the Y and Z components of the geomagnetic field from nine magnetic observatories in China, measured from 1985 to 2003. The 1991 jerk was obvious in the Y component measured but not clear for the Z component. Rapid changes in the Z components were ubiquitous around 2000 -2001, but not seen for the Y component. External effects were removed from the monthly means by comparing the monthly mean of the geomagnetic field components at the observatories with the monthly time series of the Ap geomagnetic index. However, some examples were analyzed and showed whether external effects were removed or not, there was no marked distinction in determining the jerks in China for the Y component and the Z component of the geomagnetic field. Finally, the isolines of the first differences of the annual means were used to analyze the spatial and temporal distributions of the jerks.

    Objective This study aimed to evaluate daily cholesterol intake across demographic factors and its food sources in elderly Chinese. Design A longitudinal study was conducted using demographic and dietary data for elders aged 60 and above from eight waves (1991–2011) of the China Health and Nutrition Survey. Setting The data were derived from urban and rural communities of nine provinces (autonomous regions) in China. Participants There were 16 274 participants (7657 male and 8617 female) in this study. Outcomes The primary outcome was daily cholesterol intake, which was calculated by using the Chinese Food Composition Table, based on dietary data. Results Daily consumption of cholesterol in the elderly significantly increased by 34% from 1991 to 2011 (p300 mg/day increased significantly during 1991–2011 (pmeats which ranked fourth in the contribution to total intake in 1991 was replaced by poultry in 2011. Moreover, younger elders, male elders and elders from a high-income family or a highly urbanised community had higher cholesterol intakes and larger proportions of subjects with excessive cholesterol consumption in each survey year. Conclusions The large growth in daily cholesterol intake may pose major challenges for the health of elders in China. Reduced exposure to food enriched in cholesterol is required for elderly Chinese.

The main reasons for this can be divided into two aspects: first, it is a result of compulsion by relating laws and regulations, for example, Accounting Law attaches much importance to the establishment of enterprise internal control system, Internal Accounting Control Criteria and Several Regulations Concerning the Reinforcement of Accounting Control on Money Capital issued by Ministry of Finance as well as the Regulation of Public Information Disclosure for Securities Companies issued by China Securities Regulatory Commission all make hard rules for enterprises to establish and improve their internal control systems; secondly, internal control system is propitious to the internal management of enterprises so as to help them achieve the aims of high efficiency and measuring up to standards. Design of enterprise internal control system is the conundrum and end result of study on internal control of enterprises, so this paper probed into the design of enterprise internal control system based on the fact that most Chinese enterprises have no strict internal control system or have poorly performed internal control.

    China has abundant biomass resources, which can be used as a potential source of bioenergy. However, China faces challenges implementing biomass as an energy source, because China has not developed the highly networked, high-volume biomass logistics systems and infrastructure. This paper analyzes the rural Chinese biomass supply system and models supply chain operations according to the U.S. concepts of logistical unit operations: harvest and collection, storage, transportation, preprocessing, and handling and queuing. In this paper, we quantify the logistics cost of corn stover and sweet sorghum under different scenarios in China. We analyze three scenarios of corn stover logistics from northeast China and three scenarios of sweet sorghum stalks logistics from Inner Mongolia in China. The case study shows that the logistics cost of corn stover and sweet sorghum stalk will be $52.95/dry metric ton and $52.64/ dry metric ton, respectively, for the current labor-based biomass logistics system. However, if the feedstock logistics operation is mechanized, the cost of corn stover and sweet sorghum stalk will be down to $36.01/ dry metric ton and $35.76/dry metric ton, respectively. The study also performed a sensitivity analysis to find the cost factors that cause logistics cost variation. A sensitivity analysis shows that labor price has the most influence on the logistics cost of corn stover and sweet sorghum stalk, causing a variation of $6 to $12/metric ton.

    Many kinds of factors that influence rural housing construction in Northern China are analyzed systematically and the connections between them are weighed from ecology and sustainable angles, so that an optimized green house can be built. At the same time, the energy efficient envelope structure and the method of choosing insulation material in the cost of unit thermal resistance are proposed. Integrated quality evaluation by computer shows that thermal comfort in the house would be improved remarkably for the value of PPD drops from 35%-40% to 15%, the rate of saving energy is 51.73%, much higher than the third goal of saving energy in China, and the comprehensive ecological benefit achieves good effect so as to promote the sustainable development of rural housing and community in cold areas of Northern China.

    Software engineers have developed a large body of software design theory and folklore, much of which was never validated. The results of an empirical study of software design practices in one specific environment are presented. The practices examined affect module size, module strength, data coupling, descendant span, unreferenced variables, and software reuse. Measures characteristic of these practices were extracted from 887 FORTRAN modules developed for five flight dynamics software projects monitored by the Software Engineering Laboratory (SEL). The relationship of these measures to cost and fault rate was analyzed using a contingency table procedure. The results show that some recommended design practices, despite their intuitive appeal, are ineffective in this environment, whereas others are very effective.

    Based on the experiences in road design abroad in recent years, this paper expounds the similarities and differences in geometric characteristics associated with reference speed of expressway between China and France. The comparison and analysis of definition, circular curve radius, super-elevation, easement curve, longitudinal slope, vertical curve and the driving range indicate that France has less restrictive provisions, moderate design limits, but strict line-of-sight requirement. The differences lie in the selection of parameters, design concepts and approaches under objective environments. Compared with the address of Chinese standards in comprehensiveness and practicability, French standard is more flexible to grant designers with more rules to play in design.%结合近年在海外道路工程设计方面的经验,对比阐述中国与法国规范关于城市快速路参考速度相关几何特性的异同。通过对市政快速道路的定义、圆曲线半径、超高、缓和曲线、纵坡、竖曲线和行车视距的对比研究表明:法国规范限制性条文较少,多数设计指标限值不同程度有所放宽,而对于行车安全视距要求高。差异的主要原因是客观环境下参数取值以及设计理念、方法有别,相对于我国规范的面面俱到和操作性强的特点,法国规范总体要求比较灵活和宽松,设计者可有更大的发挥空间。

    2015-03-01

    Full Text Available Utility functions in Bayesian experimental design are usually based on the posterior distribution. When the posterior is found by simulation, it must be sampled from for each future dataset drawn from the prior predictive distribution. Many thousands of posterior distributions are often required. A popular technique in the Bayesian experimental design literature, which rapidly obtains samples from the posterior, is importance sampling, using the prior as the importance distribution. However, importance sampling from the prior will tend to break down if there is a reasonable number of experimental observations. In this paper, we explore the use of Laplace approximations in the design setting to overcome this drawback. Furthermore, we consider using the Laplace approximation to form the importance distribution to obtain a more efficient importance distribution than the prior. The methodology is motivated by a pharmacokinetic study, which investigates the effect of extracorporeal membrane oxygenation on the pharmacokinetics of antibiotics in sheep. The design problem is to find 10 near optimal plasma sampling times that produce precise estimates of pharmacokinetic model parameters/measures of interest. We consider several different utility functions of interest in these studies, which involve the posterior distribution of parameter functions.

    Solar radiation is an important energy source for plants on the earth and also a major component of the global energy balance.Variations in solar radiation incident at the earth's surface profoundly affect the human and terrestrial environment,including the climate change.To provide useful information for predicting the future climate change in China,distinctive regional features in spatial and temporal variations of the surface solar radiation (SSR) and corresponding attributions (such as cloud and aerosol) are analyzed based on SSR observations and other meteorological measurements in North and East China from 1961 to 2007.Multiple models,such as the plane-parallel radiative transfer model,empirical and statistical models,and corrclation and regrcssion analysis methods are used in the study.The results are given as follows.(1) During 1961-2007,the total SSR in North China went through a process from quickly “dimming” to slowly “dimming”,while in East China,a significant transition from “dimming” to “brightening” occurred.Although there are some differences between thc two regional variation trends,long-term variations in SSR in the two regions are basically consistent with the observation worldwide.(2) Between the 1960s and 1980s,in both North and East China,aerosols played a critical rolc in the radiation dimming.However,after 1989,different variation trends of SSR occurred in North and East China,indicating that aerosols were not the dominant factor.(3) Cloud cover contributed less to the variation of SSR in North China,but was thc major attribution in East China and played a promoting role in the reversal of SSR from dimming to brightening,especially in the “remarkable brightening” period,with its contribution as high as 70%.

    2003-01-01

    The Asian financial crisis in the late 20 th century has some long lasting effect on the air transportation industry in Asia, especially in the Great China Area. Starting from 1998, airlines in both China and Taiwan suffered some serious financial losses due to the diminishing travel demand caused by the economic recession. Airlines were forced to cut price to attract passengers and hence crashed the market discipline. A number of airline mergers and acquisitions were then driven by the markets and the governments. After China and Taiwan have both entered the World Trade Organization, some mega-merging cases were finalized in late 2002 for better fitting the world's aviation competitions. This paper reviews the nine merging and acquiring cases in the Great China Area in the past 5 years. Almost all the airlines in the area were involved. The new groups of airlines and the survival airlines are introduced. Market response to the airline mergers will also be examined. A general look over the performance of the new airlines will be discussed. And the future of the market will also be analyzed. Finally, the practices and the impacts of current inter-state mergers in the Great China Area will be examined. The study has expected a highly concentrated domestic market in both China and Taiwan. Each of the market will be dominated by three major airline groups of their own. Cross-holding equity within these 6 leading aviation groups would also be possible after further deregulations.

  11. Study on the operational safety performance indicator of nuclear power plants in China

    International Nuclear Information System (INIS)

    The operational Safety Performance Indicator system (SPI) has been more and more regarded recently for their clear and effective characteristic in safety assessment for Nuclear Power Plants (NPPs). A large developing plan for NPPs construction is being discussed and considered in P.R. China. As one of important nuclear country, China expects to ensure the normal operation of NPPs and improve the safety level. National Nuclear Safety Administration (NNSA), National Nuclear Regulatory Agency of China, has put high attention on safety and SPI area, and many endeavours and attempts have been done or being carried out for an establishment of SPI system in China. NNSA intends to build an integrated SPI system to monitor all of the NPPs operation in China, based on the SPI system currently used in the world. NNSA believes that the SPI system will help to more effectively enforce the function of surveillance and management. The paper will introduces the status of study on the operational safety performance indicator of Nuclear Power Plants in China. (author)

    Full Text Available We use the China General Social Survey (2005 and the Home Office Citizenship Survey (2005 to study civic engagement and neighbourhood trust in China and Britain in this paper. We focus on class differences in participation in sports/recreation, religion, children's/adult education and public-welfare activities, and trust in the neighbours. We find higher levels of civic involvement in Britain but greater neighbourhood trust in China. This is mainly due to structural differences. China has a large proportion of peasants who have very low levels of civic involvement but very high levels of neighbourhood trust. Among the non-peasant population, the two countries have similar levels of class differences in civic (except religious involvement. There are small class differences in China on neighbourhood trust, but marked effects in Britain. Overall, there is a greater similarity than difference in class effects in both civic engagement and social trust in the two countries. While differences in demographic attributes (and China's specific institutional arrangement, the household registration system, or hukou account for some of the observed patterns, we also find more pronounced class than demographic effects in the two countries. Class plays a major role in the development of social capital.

  13. Internal Wave Study in the South China Sea Using SAR

    2000-01-01

    Recently, the internal wave distribution maps in the China Seas have been compiled from hundreds of ERS-1/2, RADARSAT, and Space Shuttle SAR (Synthetic Aperture Radar) images from 1993 to 1999. Based on internal wave distribution map, most of internal waves in the northeast part of South China Sea were propagating westward. The wave crest can be as long as 200 km with amplitude of 100 m due to strong current from the Kuroshio branching out into the South China Sea. Based on the observations from drilling rigs near DongSha Island by Amoco Production Co., the solitons may be generated in a 4 km wide channel between Batan and Sabtang islands in Luzon Strait. The proposed generation mechanism is similar to the lee wave formation from a shallow topography. Both depression and elevation internal waves have been observed in the same RADARSAT ScanSAR image on May 4, 1998 near DongSha Island. Furthermore, depression and elevation internal waves have also been observed by SAR at the same location on the shelf in April and June, 1993 (in different seasons) respectively. Numerical models have been used to interpret their generation mechanism and evolution processes. Based on the SAR images, near DongSha Island, the westward propagating huge internal solitons are often encountered and diffracted/broken by the coral reefs on the shelf. After passing the island, the diffracted waves will re-merge or interact with each other. It has been observed that after the nonlinear wave-wave interaction, the phase of wave packet is shifted and wavelength is also changed. Examples of mesoscale features observed in SAR images, such as fronts, raincells, bathymetry, ship wakes, and oil spills will be presented. Recent mooring measurements in April 1999 near Dongsha Island, future field test ASIAEX (Asian Seas International Acoustics Experiment) planned for April 2001, and some pretest survey data will be discussed in this paper.

  16. Nonlinear integrated resource strategic planning model and case study in China's power sector planning

    International Nuclear Information System (INIS)

    In this paper we expand the IRSP (integrated resource strategic planning) model by including the external cost of TPPs (traditional power plants) and popularization cost of EPPs (efficiency power plants) with nonlinear functions. Case studies for power planning in China during 2011–2021 are conducted to show the efficacy of the model. Scenarios are compiled to compare the pathways of power planning under different policies. Results show that: 1) wind power will become competitive with technical learning, but its installation is undesirable when the external cost of coal power is not internalized; 2) the existence of popularization cost will hinder EPPs' (efficiency power plants) deployment and pure market mechanism is not enough to deliver EPPs at socially desirable scale; 3) imposition of progressive emission tax on coal power at an average of 0.15–0.20 RMB/KWh can remedy the market distortion and promote the development of wind power by a significant margin; 4) nuclear power will grow stably when its external cost is set no more than 0.187 RMB per KWh, or 87% of its internal cost. The proposed model can serve as a useful tool for decision support in the process of power planning and policy formulation for national government. - Highlights: • Improve IRSP model by adding nonlinear external and popularization cost. • The model is used to conduct China's power sector planning in 2011–2021. • Simulate the impacts of alternative energy policies on planning results. • The model can be used for joint power sector planning and policy design

    von Hippel-Lindau (VHL) disease is a rare, inherited neoplastic disease characterized by hemangioblastomas (HBL) of the central nervous system (CNS), retinal angiomas, renal cell carcinomas (RCC), pancreatic endocrine tumors (PETs), pheochromocytomas, paragangliomas, and visceral cysts. We encountered a large VHL family in northwest China and conducted a systematic screening of the family members based on their epidemiological and clinical characteristics. A self-designed questionnaire was used to collect the general sociodemographic and health information of the family members. For the preliminary family screening, physical examination and abdomen B ultrasonography were performed. The suspected patients were subjected to cranial computerized tomography and fundus examination. The clinical data of the patients with confirmed VHL disease were collected from hospital records. A total of 63 lineal descendants in six generations were observed in the family (generations O, A, B, C, D, E), including 9 dead suspected cases (6 males, 3 females) and 10 living cases (2 males, 8 females). Among the 10 living cases, 4, 2, 1, 3, 4, 8, and 2 manifested HBLs of the CNS, PETs, RCC, pancreatic cysts, renal cysts, pheochromocytomas (4 hemi and 4 bilateral), and paragangliomas, respectively. Data showed that the morbidity of VHL disease in generation C was lower than that in generation B, but the age of onset was younger. This study is the first to report VHL disease in northwest China and VHL-associated PET cases in Chinese. Therefore, follow-up checkups of the family should be focused on younger generations. Proper family screening protocols should be followed for the treatment of patients with VHL disease. PMID:23827964

    Residential water use is gradually becoming the focus in China's municipal water supply planning and management in recent years. Little is known, however, about the residential water use in modem China due to the transition of economy and enhancement of management on water conservation. In order to better understand the characteristics of residential water use in North China, a model for identifying the determinants of residential water use was established and analyzed by using panel data and cross-section data methodologies. Then Taiyuan city, the capital city of Shanxi Province in Northern China was selected as a case study. Both the analyses and field investigation indicate that the relatively slow increase of residential water use in recent years may result from the implementation of strict laws and regulations on water conservation. And through the investigation,first-hand information about water consumption pattern, water reuse/conservation, people's attitude toward water quantity and quality, etc. have been obtained.

  4. Structural design and preliminary analysis of liquid lead–lithium blanket for China Fusion Engineering Test Reactor

    International Nuclear Information System (INIS)

    China Fusion Engineering Test Reactor (CFETR) has been proposed as an option in China to bridge the gaps between ITER and fusion power plant. Since one major goal of CFETR is to demonstrate long pulse or steady-state operation with duty cycle time ≥0.3–0.5, easier maintenance of the in-vessel components is emphasized in the design process. In this contribution, a kind of liquid lead–lithium tritium breeder blanket concept focus on the remote maintenance has been designed for CFETR. To make the pipes and mechanical connections at the rear of the blanket accessible from vacuum vessel, two kinds of guide tubes were adopted to provide passageways for remote handling tools. In order to evaluate the effects of the guide tube installation on the structural performance of the blanket, as a preliminary stage, thermal-hydraulic analysis of first wall was carried out based on the heat load obtained from 3D modeled neutronics calculations. In addition, thermal stress analysis of the first wall under normal condition was performed to evaluate the thermomechanical behavior. The preliminary analysis results validated the performance of current blanket design

In order to evaluate the effects of the guide tube installation on the structural performance of the blanket, as a preliminary stage, thermal-hydraulic analysis of first wall was carried out based on the heat load obtained from 3D modeled neutronics calculations. In addition, thermal stress analysis of the first wall under normal condition was performed to evaluate the thermomechanical behavior. The preliminary analysis results validated the performance of current blanket design.

    Full Text Available Increased life expectancy and a low birth rate are accelerating a demographic shift in China. Many young people are leaving rural areas and moving to urban centers, while others are migrating out of the country to study or pursue careers. These changes are pushing China into an aging “boom” that is challenging smaller numbers of family members to provide care for an increasing number of older adults. In addition to family responses to the need for elder care, societal responses are emerging with regard to public care for older adults, as well as care solutions related to children. This international project sought to contribute to the development of insightful alternatives for families who are challenged to provide care for older adults and children, and are seeking high quality care situations through public avenues. To that end, a group of students were invited to engage in an interdisciplinary, immersive service-learning project to address these societal needs, which involved the design of a combined nursing home, adult day program, and child day care center to be located in Beijing. Students were able to: 1 participate in an interdisciplinary student project between interior designers from the U.S. and architectural students from Beijing that addressed the universal design needs of children and older adults, 2 immerse themselves in another culture while fostering a fresh model of civic engagement, 3 design using new cultural norms combined with historic elements such as Feng Shui and sustainability principles, and 4 see the impact of social and political/government policy on modern building practices. These outcomes were compared with the diverse experiences received by other CMU students throughout their university service-learning experiences to determine the impact on their education and their desire to participate in future service-learning activities. Before research was conducted, it was hypothesized that at least 75% of students

  11. Source separation of household waste: A case study in China

    International Nuclear Information System (INIS)

    A pilot program concerning source separation of household waste was launched in Hangzhou, capital city of Zhejiang province, China. Detailed investigations on the composition and properties of household waste in the experimental communities revealed that high water content and high percentage of food waste are the main limiting factors in the recovery of recyclables, especially paper from household waste, and the main contributors to the high cost and low efficiency of waste disposal. On the basis of the investigation, a novel source separation method, according to which household waste was classified as food waste, dry waste and harmful waste, was proposed and performed in four selected communities. In addition, a corresponding household waste management system that involves all stakeholders, a recovery system and a mechanical dehydration system for food waste were constituted to promote source separation activity. Performances and the questionnaire survey results showed that the active support and investment of a real estate company and a community residential committee play important roles in enhancing public participation and awareness of the importance of waste source separation. In comparison with the conventional mixed collection and transportation system of household waste, the established source separation and management system is cost-effective. It could be extended to the entire city and used by other cities in China as a source of reference

    Korean historical constellations and their names are similar to Chinese ones. Although Korean historical astronomy is influenced by China, they have distinct differences in each shape and names of the constellations. We, therefore, compare Bocheonga (?) of the early Joseon dynasty (?, 1392 ~ 1910) preserved in Gyujanggark (?) with that of the Sui dynasty (?, 581sim618) of China written by Wang Ximing (?) in terms of star charts and descriptions of the contents. We find out that the two books are partly different all over the books. First, there are definite differences in preface, three area of constellations (?) in the heaven, and the description of the Milky Way. Second, some of constellations show different in shape, the number of stars. Especially connecting pattern in some constellations shows different in each other. Third, Joseon Bocheonga describes their colors for some stars. These mean that Joseon has a unique tradition of star maps unlike Chinese one. We also summarize the differences and distinctive characteristics of Joseon star charts compared with Chinese ones.

  13. Feasibility study of wind energy potential in China

    International Nuclear Information System (INIS)

    Remarkable economic achievements have been made in China since the economic reform in 1978. High agricultural and industrial productivity as well as rapid development of the tertiary industry and continuous improvement of living standard have resulted in a jumping power demand. The pressing need for updating the current infrastructure, power industry in particular is the key to the sustainable economic growth and continuous industrialisation. The crucial role of rural industry in economic development and the fact of over 70% of the rural population have brought a great opportunity for wind energy development. One of the most cost-effective ways to diffuse wind power technology is through technology transfer based on joint venture activities due to the enormous initial capital investment and complexity of wind power technology to ease the severe domestic power shortage. Foreign and investment will no doubt have a stimulatory effect on wind energy development in China. The future benefits in terms of technology transfer and international trade will easily outweigh the current problems and thus contribute to sustainable economic development in many years to come.

    Full Text Available With better understanding of the quality and physico-mechanical properties of rocks of dam foundation, and the physico-mechanical properties and structure design of arch dam in association with the foundation excavation of Xiluodu arch dam, the excavation optimization design was proposed for the foundation surface on the basis of feasibility study. Common analysis and numerical analysis results demonstrated the feasibility of using the weakly weathered rocks III1 and III2 as the foundation surface of super-high arch dam. In view of changes in the geological conditions at the dam foundation along the riverbed direction, the design of extending foundation surface excavation area and using consolidating grouting and optimizing structure of dam bottom was introduced, allowing for harmonization of the arch dam and foundation. Three-dimensional (3D geomechanics model test and finite element analysis results indicated that the dam body and foundation have good overload stability and high bearing capacity. The monitoring data showed that the behaviors of dam and foundation correspond with the designed patterns in the construction period and the initial operation period.

    Background Restylane, a hyaluronic acid gel, has been widely used as a dermal filler in USA and European countries. This study was designed to study the safety and efficacy of Restylane as a non-permanent dermal filler for facial augmentation therapy in China for the correction of nasolabial folds during a follow-up period of 6 months. Methods The study consisted of a screening visit, a baseline visit during which injection with Restylane was given, and follow-up visits after four weeks, three months and six months. The efficacy was subjectively assessed by comparing the treatment results between pre-treatment and post-treatment. Adverse events were analyzed by severity and duration. Results At six months post-baseline, the subjects and the investigators' independent assessment score of Wrinkle Severity Rating Scale was decreased. Global Aesthetic Improvement Scale was considered to have improved by over 90% in some cases. Adverse events related to product and injection was reported in 21.5% of the injections. A vast majority of the post-treatment reactions were mild. Conclusions The efficacy of Restylane for nasolabial fold in a Chinese population was excellent. Restylane was well tolerated and no systemic reactions or other safety concerns were raised.

    Dengue virus and its four serotypes (DENV 1-4) infect approximately 390 million people worldwide each year, with most cases in tropical and subtropical regions. Because of repeated introduction of DENV from epidemic regions and suitable weather conditions, many regions have shifted from hypo-endemicity to hyper-endemicity over recent decades. Since the first dengue outbreak in 1978, it is crucial to understand the current situation in China over nearly 40 years. The purpose of the study was to examine whether dengue in China was endemic or not, which is essential for relevant dengue control and prevention strategy implementation in China. The study, combining epidemiological characteristics of dengue from the disease notification system, phylogenetic and phylogeographic analyses, showed that all four serotypes had been detected in Guangzhou, China, which was dominated by DENV 1-2. The Maximum Likelihood tree analytic results showed that the virus detected in Guangzhou localized in different clades, except of virus of 2002 and 2003 clustered together. There existed the mutual introductions between Guangzhou and Southeast Asia. Most of the viruses were imported from Southeast Asia and the sources of outbreaks in Guangzhou mainly originated from Thailand, Indonesia, and the Philippines. The study indicates that dengue in China still remains as an imported disease, with the possibility of localization. PMID:25772205

    2006-08-15

    In China, 76% of all energy comes from coal consumption, which is the major cause of air pollution. One of the major barriers to developing sound policies for controlling air pollution is the lack of information related to the value of the health consequences of air pollution. We conducted a willingness-to-pay (WTP) study using contingent valuation (CV) methods in Chongqing, China to estimate the economic value of saving one statistical life through improving air quality. A sample of 500residents was chosen based on multistage sampling methods. A face-to-face household interview was conducted using a series of hypothetical, open-ended scenarios followed by bidding game questions designed to elicit the respondents' WTP for air pollution reduction. The Two-Part Model was used for estimations. The results show that 96% of respondents were able to express their WTP. Their mean annual income is $490. Their WTP to save one statistical life is $34,458. Marginal increases for saving one statistical life is $240 with 1year age increase, $14,434 with 100yuan monthly income increase, and $1590 with 1year education increase. Unlike developed country, clean air may still be considered as a "luxury" good in China based on the estimation of income elasticity. PMID:16580710

    Broadband antenna feeds are of particular interest to existing and future radio telescopes for multi-frequency studies of astronomical sources. Although a 1:15 range in frequency is difficult to achieve, the well-known Eleven feed design offers a relatively uniform response over such a range, and reasonably well-matched responses in E & H planes. However, given the severe Radio Frequency Interference in several bands over such wide spectral range, one desires to selectively reject the corresponding bands. With this view, we have explored the possibilities of having a multi-band feed antenna spanning a wide frequency range, but which would have good response only in a number of pre-selected (relatively) RFI-free windows (for a particular telescope-site). The designs we have investigated use the basic configuration of pairs of dipoles as in the Eleven feed, but use simple wire dipoles instead of folded dipoles used in the latter. From our study of the two designs we have investigated, we find that the desig...

  8. Seismic design parameters for nuclear power plants on the east coast of mainland China

    International Nuclear Information System (INIS)

    The need for reliable electric power for the major cities and the proximity of the ocean for cooling water has stimulated an ambitious program of nuclear power plant development along the east coast of mainland China. For the coast north of about 34 degrees latitude, seismic hazard is controlled by active faults, especially the Tan-Lu Fault. South of the zone of influence of active faults, the coast does not have the high seismic hazard of other parts of China. However, a few large earthquakes have occurred in areas of ancient geologic structures and they have no obvious origin in terms of modern tectonics. A preliminary assessment of seismic hazard indicates that a Safe Shutdown Earthquake peak horizontal ground acceleration of about 0.2 g is appropriate for much of the east coast, but values in excess of 0.4 g may be appropriate in a few areas near active faults or epicenters of strong historical earthquakes.

  9. Empirical Study on Arbitrage Opportunities in China Copper Futures Market

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    No-arbitrage bound is established with no-arbitrage theory considering all kinds of trade costs, different deposit and loan interest rate, margin and tax in fuuaes markets. The empirical results find that there are many lower bound arbitrage opportunities in China copper futures market from August 8th, 2003 to August 16th, 2005. Concretely, no-arbitrage opportunity is dominant and lower bound arbitrage is narrow in normal market segment. Lower bound arbitrage almost always exists with huge magnitude in inverted market segment. There is basically no-arbitrage in normal market because spot volume is enough, so that upper or lower bound arbitrage can be realized. There is mostly lower bound arbitrage in inverted market because spot volume is lack.

  10. Radon study in underground buildings in Chongqing, China

    International Nuclear Information System (INIS)

    Radon concentration measurements using a scintillation detector were conducted in 51 large underground buildings, which have been used as hotels, entertainment halls, restaurants, shops and factories, etc, in Chongqing, China. The results showed that the radon concentrations in these underground buildings ranged from 3.2 to 616.2 Bqm-3. The arithmetic mean was 57.6 Bqm-3, which was about 4 times as much as the mean radon concentration in ground buildings in Chongqing. The underground buildings with the highest radon concentrations were correlated with the high content of radium-226 in building materials, mechanical ventilation through interior circulatory ducts, underground depth of the building, and particularly, fissures in the walls. Measures of radon mitigation in underground buildings were recommended. (orig.). (3 refs., 5 tabs.)

    1995-01-01

    A study was made to examine the effect of advanced technology engines on the performance of subsonic airplanes and provide a vision of the potential which these advanced engines offered. The year 2005 was selected as the entry-into-service (EIS) date for engine/airframe combination. A set of four airplane classes (passenger and design range combinations) that were envisioned to span the needs for the 2005 EIS period were defined. The airframes for all classes were designed and sized using 2005 EIS advanced technology. Two airplanes were designed and sized for each class: one using current technology (1995) engines to provide a baseline, and one using advanced technology (2005) engines. The resulting engine/airframe combinations were compared and evaluated on the basis on sensitivity to basic engine performance parameters (e.g. SFC and engine weight) as well as DOC+I. The advanced technology engines provided significant reductions in fuel burn, weight, and wing area. Average values were as follows: reduction in fuel burn = 18%, reduction in wing area = 7%, and reduction in TOGW = 9%. Average DOC+I reduction was 3.5% using the pricing model based on payload-range index and 5% using the pricing model based on airframe weight. Noise and emissions were not considered.

  2. Design Study on the Advanced Recycling Reactor

    International Nuclear Information System (INIS)

    The design study on the Advanced Recycling Reactor (ARR) has been conducted. This paper presents the pre-conceptual design of the ARR that is a loop-typed sodium cooled reactor with MOX fuel. International Nuclear Recycling Alliance (INRA) takes advantage of international experience and uses the design based on Japan Sodium-cooled Fast Reactor (JSFR) as reference for FOA studies of DOE in the U.S., because Japan has conducted R and Ds for the JSFR incorporating thirteen technology enhancements expected to improve safety, enhance economics, and increase reactor reliability. ARR's goal is to generate electricity while consuming fuel containing transuranics and to be cost-competitive with LWRs of similar size. INRA proposes 3 evolutions of the ARR; ARR1, a 500 MWe demonstration plant, online in 2025; ARR2, a 1,000 MWe commercial plant, online in 2035; ARR3, a 1,500 MWe full-scale commercial plant, online in 2050. INRA believes the scale-up factor of two is acceptable increase from manufacturing and licensing points of view. Major features of the ARR1 are the following: The reactor core of 70 cm high is working for a burner of TRU. The conversion ratio of fissile is set up less than 0.6 and the amount of burned TRU is 45-51 kg/TWeh. Decay heat can be removed by natural circulation to improve safety. The primary cooling system consists of two-loop arrangement and the integrated IHX/Pump to improve economics. The steam generator with the straight doublewalled tube is used to improve reliability. The capital cost, the construction schedule and regulatory and licensing schedule are estimated. Furthermore, the technology readiness level and the technology development roadmap are studied and identified to be ready for commercial deployment. (author)

    2013-01-01

    Indoor microclimate is important for crop production and quality in greenhouse cultivation. This paper focuses on microclimate study based on a computational fluid dynamics (CFD) model of a typical plastic greenhouse (with a sector shape vertical cross-section) popularly used in central China. A radiation model is added into the CFD model so as to simulate coupling of convective transfers and radiative exchanges at the cover and the roof, instead of using the usual coupling approach based on energy balance. In addition, a fractal permeability model is innovatively adopted in the modeling of the crop canopy. Compared the numerical results with measured experimental data, the model simulation is proved with success. This model then is used to explore the microclimate variable distributions in the greenhouse. It shows that the airflow pattern, temperature and humidity profiles are different from those in a sawtooth Mediterranean-type greenhouse. The study suggests that this deliberately developed CFD model can be served as a useful tool in macroclimate research and greenhouse design investigating.

  4. Radiofrequency heating design study for TNS

    Energy Technology Data Exchange (ETDEWEB)

    Pridgeon, T.H.

    1978-03-01

    This report is divided into two sections, corresponding to two different phases of a research and design study. In the first section, a brief comparison study is presented of the various RF heating methods under consideration for tokamak application. These methods include: electron cyclotron resonance heating (ECRH), lower hybrid heating, ion cyclotron range of frequencies heating (ICRF), ion cyclotron resonance heating (ICRH), magnetoacoustic wave heating, and shear Alfven wave heating. Each method is examined according to the type(s) of plasma waves involved, wave propagation and accessibility, dominant absorption processes, possible coupling structures, expected efficiencies, and expected engineering difficulties. A specific tokamak application was chosen to provide self-consistent boundary conditions for the study. The second part of this report deals with the application of ICRF to TNS. Although coupling theory for ICRF is very uncertain at this time for devices as large as TNS, waveguides operating at a frequency equal to twice the deuteron cyclotron frequency are considered as possible coupling structures. A possible design is presented that has been arrived at through consideration of several factors.

  10. Extreme climate events,migration for cultivation and policies:A case study in the early Qing Dynasty of China

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Based on the historical records of the annual increase in the workforce (men older than 16 years of age), the annual new taxed cropland in the Shengjing area (Northeast China), the extreme climate events in North China, and related management policies in Northeast China during 1661―1680, a case study has been conducted to investigate the relationship between the extreme climate events in North China and the migration to Northeast China for cultivation. This study has found that the migration to Northeast China for cultivation from 1661 to 1680 was a response to the drought events that occurred in North China. The upsurge of migration, which occurred in 1665―1680, was a response to the drought period during 1664―1680 in North China while the fewer disasters period in Northeast China. There were three migratory peaks during the upsurge of migration, which corresponded to the three drought events. The peaks of migration, however, often lagged behind the drought events about 1―2 years. The encourag-ing-migration policy, which was adopted to encourage cultivation in Northeast China, did not produce much migration into the region in the early Qing Dynasty. It did, however, provide a policy background, which ensured more than 10000 migrants per year to Northeast China when North China suffered from drought/flood disasters. As a response to the highest peak of migration induced by the severe droughts in North China during 1664―1667, a prohibiting-migration policy restricted further migration to Northeast China was carried out in 1668. Although the prohibiting-migration policy could not entirely stop the migrants fleeing from famine in North China to Northeast China, the migrants and cultivation were significantly reduced under the policy. The frequent changes of the policy on the years when taxation started after the land was cultivated were also related to climate events.

    Science.gov (United States)

    1997-01-01

    This report addresses the technical feasibility and design of a rocket based MHD generator using a sub-scale LOx/RP rocket motor. The design study was constrained by assuming the generator must function within the performance and structural limits of an existing magnet and by assuming realistic limits on (1) the axial electric field, (2) the Hall parameter, (3) current density, and (4) heat flux (given the criteria of heat sink operation). The major results of the work are summarized as follows: (1) A Faraday type of generator with rectangular cross section is designed to operate with a combustor pressure of 300 psi. Based on a magnetic field strength of 1.5 Tesla, the electrical power output from this generator is estimated to be 54.2 KW with potassium seed (weight fraction 3.74%) and 92 KW with cesium seed (weight fraction 9.66%). The former corresponds to a enthalpy extraction ratio of 2.36% while that for the latter is 4.16%; (2) A conceptual design of the Faraday MHD channel is proposed, based on a maximum operating time of 10 to 15 seconds. This concept utilizes a phenolic back wall for inserting the electrodes and inter-electrode insulators. Copper electrode and aluminum oxide insulator are suggested for this channel; and (3) A testing configuration for the sub-scale rocket based MHD system is proposed. An estimate of performance of an ideal rocket based MHD accelerator is performed. With a current density constraint of 5 Amps/cm(exp 2) and a conductivity of 30 Siemens/m, the push power density can be 250, 431, and 750 MW/m(sup 3) when the induced voltage uB have values of 5, 10, and 15 KV/m, respectively.

    Full Text Available In this study, the optical characteristics, thermal characteristics, electrical characteristics of the LED device are studied. After analysis of the significance of the optical model, we establish the model of the LED light source using optical simulation software to analyze the impact of modeling four factors and law, based on ray tracing model intensity distribution with the manufacturers. On this basis, we expand the LED secondary optical design, namely, increasing of LDE method to the light level. After comparing different forms of non-imaging optical components, combined with the actual situation, the final choice is the system composed of rotating parabolic reflector with LDE. Besides, the reflected changing the relative position of the body and LDE space lead to the normal light intensity of the entire system appearing two peaks, but their causes are different. In addition, the method of combining theoretical analysis and computer simulations to study the distribution of LDE array illumination is utilized. Formula on the illumination distribution in the LDB array to a plane parallel thereto is deduced, which is verified by computer simulation and agrees well with it. A quantitative study of the factors affecting the road surface illuminance distribution is made on the basis of previous study, combined with the actual road lighting works. These factors are: LDE array form, the number of LED, spacing between LDE, LDE interval between the street lamps. The derived entire road illumination distribution formula and the corresponding curve gives a basic method for the analysis of such practical problems related outcomes for the LDE illumination optical system design and research basis.

    This paper employs data envelopment analysis to evaluate energy utilization efficiency between China and Taiwan from 2002 to 2007. The most important contributions of this paper are the clear description of the systematic process of energy utilization efficiency, the efficiency comparison between China and Taiwan, the remarkable demonstration of their outputs through two non-desirable outputs (CO{sub 2} emissions and SO{sub 2} emissions) in the data envelopment analysis framework, and the valuable results and insights gained from the application of economic development and environmental protection. Empirical results show that the Eastern region of China enjoy higher energy utilization efficiency than the Western region. Energy utilization efficiency in Taiwan is higher than that in the Eastern region of China. In China, CO{sub 2} emissions were 11.28% greater than they should be (from 2002 to 2007). By contrast, CO{sub 2} emissions in Taiwan were only 1.50% in excess of what they should be since Taiwan began conducting an uninterrupted energy-saving policy and a CO{sub 2} emission regulation policy. Finally, this study employs the business strategy matrix constructed by the Boston Consulting Group (BCG Matrix) to illustrate individual evidence of the relationship between economic development efficiency and greenhouse gas efficiency.

    2011-01-01

    Full Text Available East China Sea is one of the four sea areas in China, which possesses peculiar ecological environment and many kinds of living creatures, especially the microorganisms. We established the East China Sea microorganism library (during 2006–2010 for the first time, which stored about 30000 strains that covered most kinds of the species. In this paper, 395 pure strains of East China Sea microorganism library which belong to 33 different genera were mainly introduced. Sulfitobacter, Halomonas, Bacillus, Pseudoalteromonas, and Idiomarina were the most dominant species. On the large-scale biological activity screening of the 395 strains, 100 strains possess different biological activities based on different screening models, of which 11.4% strains have antibacterial activities, 15.9% have cytotoxicity activities, and 6.1% have antioxidation activities. Besides, the secondary metabolites of 6 strains with strong biological activities were studied systematically; diketopiperazines and macrocyclic lactones are the active secondary metabolites. The species and the biological activity of microorganisms diversity, the abundant structure type of the secondary metabolites, and their bioactivities all indicate that East China Sea is a potent marine microorganisms-derived developing resource for drug discovery.

  20. A pilot study for control of hyperendemic cystic hydatid disease in China.

    Directory of Open Access Journals (Sweden)

    Wenbao Zhang

    Full Text Available BACKGROUND: Cystic hydatid disease (CHD is a global parasitic zoonosis caused by the dog tapeworm, Echinococcus granulosus. The disease is hyperendemic in western China because of poor economic development; limited community knowledge of CHD; widespread, small-scale household animal production; home killing of livestock; and the feeding of dogs with uncooked offal. METHODOLOGY/PRINCIPAL FINDINGS: A control program focusing on monthly praziquantel (PZQ treatment of all registered dogs and culling unwanted and stray dogs has been designed to control CHD in hyperendemic areas in China. A pilot field control project in two counties (Hutubi and Wensu in Xinjiang, China showed that after 4 years of treatment, the prevalence of dogs with E. granulosus was reduced from 14.7% and 18.6%, respectively, to 0%, and this caused a 90%-100% decrease of CHD in sheep born after commencement of the control program. CONCLUSIONS/SIGNIFICANCE: The strategy aimed at preventing eggs being released from dogs into the environment by treating animals before adult tapeworms are patent can decrease E. granulosus transmission and considerably reduce hyperendemic CHD. Monthly treatment of dogs with PZQ and culling unwanted and stray dogs have been shown to be an efficient, highly cost-effective and practicable measure for implementation in rural communities. As a result, the Chinese Ministry of Health has launched an extensive CHD control program in 117 counties in western China using this control strategy.

    More than 15 million people in the greater area of Beijing are still suffering from severe air pollution levels caused by sources within the city itself but also from external impacts like severe dust storms and long range advection from the southern and central part of China. Within this context particulate matter (PM) is the major air pollutant in the greater area of Beijing (Garland et al., 2009). PM did not serve only as lead substance for air quality levels and therefore for adverse health impact effects but also for a strong influence on the climate system by changing e.g. the radiative balance. Investigations on emission reductions during the Olympic Summer Games in 2008 have caused a strong reduction on coarser particles (PM10) but not on smaller particles (PM2.5). In order to discriminate the composition of the particulate matter levels, the different behavior of coarser and smaller particles investigations on source attribution, particle characteristics and external impacts on the PM levels of the city of Beijing by measurements and modeling are performed: a) Examples of long term measurements of PM2.5 filter sampling in 2010/2011 with the objectives of detailed chemical (source attribution, carbon fraction, organic speciation and inorganic composition) and isotopic analyses as well as toxicological assessment in cooperation with several institutions (Karlsruhe Institute of Technology (IfGG/IMG), Helmholtz Zentrum München (HMGU), University Rostock (UR), Chinese University of Mining and Technology Beijing, CUMTB) will be discussed. b) The impact of dust storm events on the overall pollution level of particulate matter in the greater area of Beijing is being assessed by the online coupled comprehensive model system COSMO-ART. First results of the dust storm modeling in northern China (2011, April 30th) demonstrates very well the general behavior of the meteorological parameters temperature and humidity as well as a good agreement between modeled and

With the recent growing focus on China's energy use and emission mitigation potential, a range of Chinese outlook models have been developed across different institutions including in China's Energy Research Institute's 2050 China Energy and CO2 Emissions Report, McKinsey & Co's China's Green Revolution report, the UK Sussex Energy Group and Tyndall Centre's China's Energy Transition report, and the China-specific section of the IEA World Energy Outlook 2009. At the same time, the China Energy Group at Lawrence Berkeley National Laboratory (LBNL) has developed a bottom-up, end-use energy model for China with scenario analysis of energy and emission pathways out to 2050. A robust and credible energy and emission model will play a key role in informing policymakers by assessing efficiency policy impacts and understanding the dynamics of future energy consumption and energy saving and emission reduction potential. This is especially true for developing countries such as China, where uncertainties are greater while the economy continues to undergo rapid growth and industrialization. A slightly different assumption or storyline could result in significant discrepancies among different model results. Therefore, it is necessary to understand the key models in terms of their scope, methodologies, key driver assumptions and the associated findings. A comparative analysis of LBNL's energy end-use model scenarios with the five above studies was thus conducted to examine similarities and divergences in methodologies, scenario storylines, macroeconomic drivers and assumptions as well as aggregate energy and emission scenario results.

    The controlling and influencing effects of the joint action of plates surrounding China on strong earthquakes in Chinese mainland are discussed, and the characteristics of seismic activities in the West of China and neighboring regions are further studied. The results show that the seismic activity in the West of China and neighboring regions not only has the characteristics of high tide and low tide alternation but also has the characteristics of rising in one region while falling in another, and the rise and fail of seismicity are in some proportion. The above characteristics are useful for the prediction of main body region of strong earthquakes in Chinese mainland, especially for the judgement of the ending time of the high fide period.

    Background Most data about psychological factors relating to acute myocardial infarction (AMI) were obtained from studies carried out in western countries. Results from small descriptive cross-sectional studies in China were inconclusive. The aim of this study was to explore possible associations between psychological risk factors and AMI among the Chinese population with a large-scale case-control study.Methods This study was part of the INTER-HEART China study, itself part of the large international INTER-HEART study of cardiovascular risk factors. In this case-control study, 2909 cases and 2947 controls were recruited from 17 cities.Psychological stress, negative life events, depression and controllability of life circumstances were assessed.Results Cases reported more psychological stress at home or work and odds ratios (ORs) were 3.2 (95% CI 2.1-4.9)for permanent stress and 2.1 (95% CI 1.5-2.8) for several periods of stress respectively. More cases experienced depression compared with controls (19.6% vs. 9.3%) and ORs were 2.2 (95% CI 1.9-2.6). Subjects with 1, 2 and 3 or more depressive symptoms had increased risk of AMI by 2.1, 2.2 and 2.6 fold, respectively, i.e., more depressive symptoms were associated with higher risks of AMI (P for trend <0.0001). Women had a greater risk of AMI from depression (OR 3.0, 95% CI 2.2-4.0) compared to men (OR 2.0, 95% CI 1.6-2.4), P for interaction =0.0364. Negative life events in subjects were associated with increased risk of AMI, OR 1.7 (95% CI 1.4-2.0) for one event and 1.8 (95% CI 1.3-2.4) for two or more events. High levels of controllability of life circumstances reduced the risk for AMI (OR 0.8, 95%CI 0.7-1 .0).Conclusions Several psychological factors were closely associated with increased AMI risk among Chinese population.Psychological stress had a greater AMI risk in men but depression was more significant among women.

  19. Design of Dwellings and Interior Family Space in China: Understanding the History of Change and Opportunities for Improved Sustainability Practices

    Directory of Open Access Journals (Sweden)

    Adrian Pitts

    2014-10-01

    Full Text Available This paper reviews briefly the recent history of dwelling design in China. It notes the rapid changes that have taken place since the 1980s and identifies the way contemporary procurement processes leave out the final fit-out and decoration/refurbishment. A range of stakeholders were interviewed, and access was gained to drawings and other technical data that indicated how the secondary processes were carried out. These are largely ungoverned by regulation in the same way necessary for initial design. The key group is the occupants who drive the fit-out and decoration according to personal and cultural requirements, but often with less than perfect understanding of sustainability. The interior design industry has developed rapidly over the same period and was initially lacking in professional knowledge and understanding (something which can still be found. Advice provided to dwelling occupants was based more on appearance than function and efficiency. Over the same period, beneficial modifications to construction processes have been introduced in relation to structural design, and it should be possible to do the same for sustainability-related design issues. The paper advocates: more regulation; better assessment techniques; more information and guidance for home-owners; and a greater focus on energy issues.

  20. Current status of safety design and safety analysis for China ITER helium coolant ceramic breeder test blanket system long

    International Nuclear Information System (INIS)

    Helium Coolant Ceramic Breeder (HCCB) Test Blanket System (TBS) designed by China are planned to be tested in ITER to validate key technologies, including demonstration of nuclear safety, for future fusion reactor breeding blankets. Furthermore, in order to be operated in ITER, a nuclear facility (INB) recognized by French nuclear safety authority, safety design and safety analysis of the TBS are mandatory for the licensing procedures. This paper summarizes the status at current design phase with following main elements: The main radiological source terms in the system are tritium and activation products. Nuclear and tritium analysis are performed to identify their inventories and distributions in system. Multiple confinement barriers are considered to be the most essential safety feature. French regulation for pressure equipment and nuclear equipment (ESP/ESPN regulations) will be followed to ensure the system integrities. ALARA principle is kept in mind during the whole safety design phases. Protective actions including choice of advanced materials, improvement of shielding, optimization of operation and maintenance activities, usage of remote handling operations, zoning and access control have been considered. Passive safety is emphasized in the system design, only minimal active safety functions including call for fusion plasma shutdown and isolation of TBM from ex-vessel ancillary systems. High reliability and redundancies are required for components related to these functions. Several accidents have been identified and analyzed. Consider the limited inventories in the system and the intrinsic safety of fusion device, positive conclusions have been obtained. (author)

  1. Carbon prices and CCS investment: A comparative study between the European Union and China

    International Nuclear Information System (INIS)

    Carbon Capture and Storage is considered as a key option for climate change mitigation; policy makers and investors need to know when CCS becomes economically attractive. Integrating CCS in a power plant adds significant costs which can be offset by a sufficient CO2 price. However, most markets have failed: currently, the weak carbon price threatens CCS deployment in the European Union (EU). In China, a carbon regulation is appearing and CCS encounters a rising interest. This study investigates two questions: how much is the extra-cost of a CCS plant in the EU in comparison with China? Second, what is the CO2 price beyond which CCS plants become more profitable than reference plants in the EU and in China? To address these issues, I conducted a literature review on public studies about CCS costs. To objectively assess the profitability of CCS plants, I constructed a net present value model to calculate the Levelised Cost of Electricity and the breakeven CO2 price. CCS plants become the most profitable plant type beyond 115 €/tCO2 in the EU vs. 45 €/tCO2 in China (offshore transport and storage costs). I advise on the optimal plant type choice depending on the CO2 price in both countries. - Highlights: • I develop a method to objectively update and compare CCS costs in the EU and China. • To represent investment choices, intra and inter CO2 switching prices are required. • EU CCS plants are profitable for a CO2 price higher than 115 €/t (offshore storage). • Chinese CCS plants are profitable beyond 45 €/tCO2 (35 €/tCO2 with onshore storage). • With 2030 projections, CCS (coal) plants are profitable in China but not in the EU

    Thickened heavy oils in China are genetically characteristic of continenta .As to their physico-chemical properties,these oils are very high in viscosity and low in sulphur and trace element con-tents.In the group constituents,the concentrations of non-hydrocarbons and asphaltene are very high but those of saturated hydrocarbons and aromatics are very low.The gas chromatograms of alkanes show that these heavy oils have high abundances of iso-alkanes and cyclic hydrocarbons.In all the steroids and terpenoids ,bicyclic sesquiterpenoids,tricyclic diterpenoids,re-arranged steranes and gammacerane are strongly bildegradation-resistent.The formation of heavy oil reservoirs is controlled mainly by late basin ascendance,biodegradation,flushing by meteoric water and oxidation in the oil-bearing formations.Ac-cording to their formation mechanisms,heavy oil reservoirs can be classified as four categories:weathering and denudation,marginal oxidation,secondary migration and thickening of bottom water .Spacially,heavy thick oil reservoirs are distributed regularly:they usually show some paragenetic relationships with normal oil reservoirs.Heavy oil reservoirs often occur in structural highs or in overlying younger strata.Their burial depth is about 200m.Horizontally,most of them are distributed on the margins of basins or depressions.

  3. Simulation study of UO2 kernel reduction furnace design

    International Nuclear Information System (INIS)

    Based on the N-S equations and the k-ε turbulence model, different kinds of UO2 kernel reduction furnace equipment in PBMR, South Africa and INET, China were numerically simulated using computational fluid dynamics method. The simulation results show that these two kinds of furnace designs can not be achieved on the uniform distribution of gas flow in the axial direction, but show large volume at the top and small volume at the bottom of the furnace, and this is one of the reasons of non-uniform particle reduction. Improved design was proposed based on the analysis of changes of axial pressure in the furnace. Simulation results demonstrate that the improved furnace design is suitable for obtaining a more uniform distribution of the gas in the axial direction. It can be concluded that the improved furnace design will improve particle reduction effects. (authors)

    2013-03-28

    The Internet has become a major part of the global communications infrastructure supporting modern-day socio-economic development, social progress and technological innovation. Invented 30 years ago, today the Internet is facing severe challenges. Many countries have funded research projects on the new-generation Internet, such as GENI, FIND, FIRE and CNGI, in an effort to solve these challenges. In addition, over the past few years, the networking research community has engaged in an ongoing conversation about how to move the Internet forward, and there are now two different approaches towards Internet research. The first approach is based on using the existing Internet architecture to solve the major technical challenges-this is called 'evolutionary' research. The other, which is called the 'clean slate', involves the design of an entirely new Internet architecture. In the first part of this paper, the basic features of the next generation Internet and its principal contradictions are analysed. Then a survey of recent progress in the study of the next generation Internet in China is discussed. Finally, the focus and direction for the next step in research are presented as based on fundamental research into the international next generation Internet architecture, and the many new innovative demands placed on Internet architecture in recent years.

    1996-03-01

    A two and a half layer oceanic model of wind-driven, thermodynamical general circulation is applied to study the interannual oscillation of sea surface temperature (SST) in the South China Sea (SCS). The model consists of two active layers: the upper mixed layer (UML) and the seasonal thermocline, with the motionless abyss beneath them. The governing equations which include momentum, continuity and sea temperature for each active layer, can describe the physics of Boussinseq approximation, reduced gravity and equatorial β-plane. The formulas for the heat flux at the surface and at the interface between two active layers are designed on the Haney scheme. The entrainment and detrainment at the bottom of the UML induces vertical transport of mass, momentum and heat, and couples of dynamic and thermodynamic effects. Using leap-frog integrating scheme and the Arakawa—C grid the model is forced by a time-dependent wind anomaly stress pattern obtained from category analysis of COADS. The numerical results indicate that there is a kind of oscillation with about 30 months period. The paper supports the opinion that the SST interannual oscillation is the oceanic response to the forcing by monsoon wind anomalies in the SCS.

    A devastating debris flow occurred in Zhouqu of Gansu Province, China, on 8th August 2010, resulting in a catastrophic disaster, with 1463 people being perished. The debris flow valleys, as other numerous debris valleys in the mountainous region, had preventive engineering constructions, such as check dames, properly designed based on common engineering practices for safe guiding the town located right on the debris flow fan. However, failures of such preventive measures often cause even heavier disasters than those that have no human interactions, as the mitigations give a false safety impression. Given such a weird situation and in order to explore a much more effective disaster prevention strategy against debris flows in the mountainous region, this paper makes a comparative study based on two cases in the area of which one had preventive structures and one hasn't. The result shows that inappropriate mitigation measures that have commonly been applying in the disaster reduction practices in the region are of questionable. It is concluded that going with the nature and following with the natural rules are the best strategy for disaster reduction in the region. Key words: debris flow disasters, disaster reduction strategy, preventive measures
