R. China September, 1999 Assessment Institution: GuangxiEnvironmental Protection Scientific Research Institute Assessment Certificate: No. 0949 Public Disclosure Authorized Director: Wang Censheng Project Chief: Yu Wanli Deputy Project Chief: Gan Zhengqi I Members of Project Group: Niu Ling, Fan Zhenhui, Gu Zhanqi, Chen Bei Preface The assessed project herewith belongs to the World Bank Aided project under the Highway Network Improvement Program in poverty-stricken area of Shuiren-Nanning Highway project, it consists of ten sub-projects of road improvement. The target of the project construction is to improve the transportation conditions of the poor area nearby the main project, to promote local economic development and upgrade the comprehensive traffic capacity of the road network in this region. According to the environmental management policies for project construction of the World Bank, Guangxi Roads & Highways Bureau entrusted Guangxi Environmental Protection Scientific Research Institute with the task to compile the IEEs and EAPs in December of 1998. On this basis, our Institute conducted successively two times of field environmental investigation respectively in December of 1998 and April of 1999. In February of 1999, we finished the IEE and EAP for the seven sections including G209 Qintang - Wuli sub-project. In April of 1999, upon exchanged ideas with Guangxi CommunicationsDepartment, we made necessary adjustment, amendment and addition to this report according to the suggestions proposed by the World Bank Delegation during its preparation mission. We also added G324 Baise - Tianlin section, G323 Pingcun - Juxu section and formed a revised report. In August of 1999, the World Bank delegation undertook detailed examiniation of the revised report and put forward written suggestion for revision. According to the revison suggestion, we again made necessary adjustment and revision, thus this Report is done. I Contents PART ONE INITIAL ENVIRONMENTAL EVALUATION (IEE) 0 1.

Wujia - Hepu section, Changle - Hepu county section are located in the south of Guangxi, the geomorphy belongs to alluvial plain and micro hillock around 30 km away from the Beibu Gulf. Jiuxu- Pingcun, Baise-Tianlin are located in the west of Guangxi, the formnerbelongs to karst topography showing continuos mountains and embedded with various sizes of round or honeycomb low- laying land; the latter are mainly hills and basins. Except for Pingcun-Jiuxu section, the eight sections are mostly of twisted roads of many curves and big slopes. Baise-Tianlin section has many small slopes, and the other six sections are mostly of smooth area but with some undulation. The districts of these sections are mainly of plains and micro hills. Details refer to Table 2-1 2.1.2 Climate The climates passed by the eight sections do not vary distinctly belonging to subtropical monsoon climate, showing long summer and short winter, adequate sunlight and rainfall, rainfall and heat of same season, long frost-free season, distinct dry and wet seasons etc. The district is also one of those districts of frequent disastrous weather. According to meteorological data of counties and cities, the summer begins from end of April and ends at mid of October nearly half a year.

It is a daunting task to eradicate tuberculosis completely in Heng County due to a large transient population, human immunodeficiency virus/tuberculosis coinfection, and latent infection. Thus, a high-precision forecasting model can be used for the prevention and control of tuberculosis. In this study, four models including a basic autoregressive integrated moving average (ARIMA) model, a traditional ARIMA–generalized regression neural network (GRNN) model, a basic GRNN model, and a new ARIMA–GRNN hybrid model were used to fit and predict the incidence of tuberculosis.

  • Report on Domestic Animal Genetic Resources in China

    Report on Domestic Animal Genetic Resources in China

    Country Report for the Preparation of the First Report on the State of the World’s Animal Genetic Resources Report on Domestic Animal Genetic Resources in China June 2003 Beijing CONTENTS Executive Summary Biological diversity is the basis for the existence and development of human society and has aroused the increasing great attention of international society. In June 1992, more than 150 countries including China had jointly signed the "Pact of Biological Diversity". Domestic animal genetic resources are an important component of biological diversity, precious resources formed through long-term evolution, and also the closest and most direct part of relation with human beings. Therefore, in order to realize a sustainable, stable and high-efficient animal production, it is of great significance to meet even higher demand for animal and poultry product varieties and quality by human society, strengthen conservation, and effective, rational and sustainable utilization of animal and poultry genetic resources. The "Report on Domestic Animal Genetic Resources in China" (hereinafter referred to as the "Report") was compiled in accordance with the requirements of the "World Status of Animal Genetic Resource " compiled by the FAO. The Ministry of Agriculture" (MOA) has attached great importance to the compilation of the Report, organized nearly 20 experts from administrative, technical extension, research institutes and universities to participate in the compilation team. In 1999, the first meeting of the compilation staff members had been held in the National Animal Husbandry and Veterinary Service, discussed on the compilation outline and division of labor in the Report compilation, and smoothly fulfilled the tasks to each of the compilers.

    Anisotropic Patterns of Liver Cancer Prevalence in Guangxi in Southwest China: Is Local Climate a Contributing Factor?

    DOI:http://dx.doi.org/10.7314/APJCP.2015.16.8.3579 Anisotropic Patterns of Liver Cancer Prevalence in Guangxi in Southwest China: Is Local Climate a Contributing Factor? RESEARCH ARTICLE Anisotropic Patterns of Liver Cancer Prevalence in Guangxi in Southwest China: Is Local Climate a Contributing Factor? Wei Deng1&, Long Long2&*, Xian-Yan Tang3, Tian-Ren Huang1, Ji-Lin Li1, Min- Hua Rong1, Ke-Zhi Li1, Hai-Zhou Liu1 Abstract Geographic information system (GIS) technology has useful applications for epidemiology, enabling the detection of spatial patterns of disease dispersion and locating geographic areas at increased risk. In this study, we applied GIS technology to characterize the spatial pattern of mortality due to liver cancer in the autonomous region of Guangxi Zhuang in southwest China. A database with liver cancer mortality data for 1971-1973, 1990-1992, and 2004-2005, including geographic locations and climate conditions, was constructed, and the appropriate associations were investigated. It was found that the regions with the highest mortality rates were central Guangxi with Guigang City at the center, and southwest Guangxi centered in Fusui County. Regions with the lowest mortality rates were eastern Guangxi with Pingnan County at the center, and northern Guangxi centered in Sanjiang and Rongshui counties. Regarding climate conditions, in the 1990s the mortality rate of liver cancer positively correlated with average temperature and average minimum temperature, and negatively correlated with average precipitation. In 2004 through 2005, mortality due to liver cancer positively correlated with the average minimum temperature. Regions of high mortality had lower average humidity and higher average barometric pressure than did regions of low mortality.

In this study, the genetic diversity among 9 accessions of S. glabrafrom different regions was analyzed by using therandom-amplified polymorphic DNA (RAPD) markersand the genetic relationship was revealed by cluster analysis and correlation coefficient analysis. Polymerase chain reactions were performed for 22 RAPD primers.Total 117 loci were detected by 22 primers and the amplified bands ranged from 3 to 9 with an average of 5.32 bands per pair of primer.
