柬埔寨王国金矿资源与正在兴起的金矿业   总被引:3,自引:1,他引:2  
周军  黎武兴  高风亮 《黄金》2003,24(8):7-11
柬埔寨已知有19个金矿区,其中数百个金矿点星罗棋布,大多数原生金矿与晚中生代闪长岩一花岗闪长岩火成活动有关,位于中部湄公河流域冲积平原和周围浅山地段的金矿区还广泛发育有冲积、坡积型砂金矿,较低的研究程度及有利的地质背景暗示着较大的探矿潜力。目前,柬埔寨政治稳定,国家颁布许多矿产资源管理法规,公路、电力、通讯等基础条件得到很大改善。包括中国在内的一些外国矿业公司投资金矿踊跃,逐步结束过去以民采为主的混乱局面。除资源机遇之外,柬埔寨新兴金矿市场尚存在着引进矿业设备等商机。  相似文献

A large amount of combustibles are stored in small newspapers and magazine shops in terminal halls known as news agents in the Far East. Fire safety for those small shops located in crowded public transport interchanges should be evaluated carefully. In carrying out fire hazard assessment, the possible heat release rates should be estimated so that consequences of a fire can be assessed. As the shops are small with easily ignited combustibles, transition to a postflashover fire would be rapid. Therefore, the resultant heat release rates should be measured by burning those combustibles under flashover conditions. Hazard assessments based on full-scale burning tests for postflashover news agent fires performed in remote areas in China are reported in this paper. The effect of reducing the heat release rate by discharging water mists is illustrated. Such fire suppression systems are recommended for use in such shops.  相似文献

The collection of articles in this special section provides a much-needed examination of the state of psychological assessment in various Asian countries or societies. In particular, the contributors review and critique assessment of personality, depression and anxiety, children and adolescents, and neuropsychological evaluation. The reviews cover the use of, and research on, imported measures (Western derived) as well as indigenous measures that were developed locally. The articles make a valuable contribution toward understanding not only the state of assessment in Asia but also larger issues such as the universal applicability of assessment instruments and the cross-cultural validity of models of human behavior.

Mechanisation of large‐scale agricultural fields often requires the application of modern technologies such as mechanical power, automation, control and robotics. These technologies are generally associated with relatively well developed economies. The application of these technologies in some developing countries in Africa and Asia is limited by factors such as technology compatibility with the environment, availability of resources to facilitate the technology adoption, cost of technology purchase, government policies, adequacy of technology and appropriateness in addressing the needs of the population. As a result, many of the available resources have been used inadequately by farmers, who continue to rely mostly on conventional means of agricultural production, using traditional tools and equipment in most cases. This has led to low productivity and high cost of production among others. Therefore this paper attempts to evaluate the application of present day technology and its limitations to the advancement of large‐scale mechanisation in developing countries of Africa and Asia. Particular emphasis is given to a general understanding of the various levels of mechanisation, present day technology, its management and application to large‐scale agricultural fields. This review also focuses on/gives emphasis to future outlook that will enable a gradual, evolutionary and sustainable technological change. The study concludes that large‐scale‐agricultural farm mechanisation for sustainable food production in Africa and Asia must be anchored on a coherent strategy based on the actual needs and priorities of the large‐scale farmers. © 2016 Society of Chemical Industry  相似文献

Malnutrition continues to be a major public health challenge especially in South Asian developing countries. The aim of the present review is to spotlight the magnitude of the prevalence of malnutrition and its dynamics in South Asian region and to suggest potential approaches for the prevention and control of this issue of public health significance. An extensive review of literature, covering malnutrition and its determinants, health and economic consequences and pragmatic preventive strategies was performed on computer based bibliographic databases (PubMed, Google Scholar, Scopus, Medline and Sciencedirect.com) to retrieve abstracts and full texts for India, Pakistan, Bangladesh, Sri Lanka and Nepal. All relevant titles and abstracts were examined and evaluated for malnutrition and its prevalence in South Asia. The results revealed malnutrition to be a major public health problem and a potential cause of high disease burden and mortality in South Asia. Compelling evidence suggests malnutrition to be the leading cause of stunting, wasting and underweight with drastic economic consequences among vulnerable populations. Reduced cognitive performance and low productivity have also been associated with micronutrients malnutrition. Suboptimal breastfeeding, inadequate food supply, micronutrient deficiencies, low household income, poor health care system, increased healthcare costs, illiteracy, unhygienic and substandard living, inappropriate child's care and the caregiver, food insecurity and on top of that vicious cycle of poverty, have been recognized as principal indicators for growing malnutrition prevalence in South Asia. Global organizations, local governments, program managers, NGOs, academia, industry in particular and the society at large need to take up the challenge to completely confiscate malnutrition from the region for economic prosperity and a healthier future.  相似文献

The article proposes a methodological approach to the development of the tools for studying the international electro-hydrogen system creation in Northeast Asia. The term "hydrogen carrier" was introduced and its definition was given. The resource, economic and technological prerequisites for the development of the unified regional infrastructure to produce, transfer, transform and utilise both electricity and "hydrogen carriers" for consumers of energy services are considered.The author points out the need for a comprehensive consideration of technological, economic, social and political factors when developing such a complex technical system, which affects the diverse actors' interests. In order to create mutual understanding and balance the stakeholders’ interests, the tool to evaluate the efficiency of such a system is necessary. The use of mathematical models is becoming one of the most vital and widespread techniques employed for this purpose. Thereby, the article deals with the structure and the development stages of a regional electro-hydrogen model for Northeast Asia.The review of models that address the issues of hydrogen technologies and renewable energy integration into energy supply systems is given. The main types of models used to describe such technical and economic systems are identified and it is concluded that the development of a two-level modelling system is necessary. The production and transport models at the upper (international) level should be the core of the proposed models system. At the lower level (the "green hydrogen carriers" production), the models of optimal resource management are required to determine the composition and parameters of the technological equipment.Step-by-step development of the modelling system is proposed. The first stage is the simplest scenario where only solar and wind energy is considered as an energy source. At this stage, it is possible to weed out inefficient technologies and identify targeted technologies and mechanisms for multilateral regional cooperation. The second stage should balance the interests of the actors and stakeholders. Here, the traditional renewable energy (biomass, hydro and pumped storage) along with carbon (thermal) and nuclear power generation, as well as other ("carbon") hydrogen technologies will become available for consideration. The final, third stage of the research tools development, will require separate accounting of "green" and "carbon" energy to consider certification mechanisms and energy pricing when building the international hydrogen system in Northeast Asia.In conclusion, the structure of the first stage production and transport model is described. This model will allow estimating the comparative effectiveness of different electric and hydrogen technologies to deliver green energy to consumers in the Northeast Asian economies.  相似文献

南传佛教是泰、缅、柬、老等东南亚国家以及我国傣族地区具有主体地位的宗教形态,普及面广、信徒众多、影响深刻。作为其重要组成部分的南传佛教壁画,可谓是中南半岛上最具典型意义的美术形式。它既是信奉南传佛教信众的情感流露和心灵写照,又是其精神世界与审美理想的表征。本文依托田野考察所获取的一手资料及相关文献,对东南亚南传佛教壁画的历史沿革、内容题材、形式风格、表现手法和发展现状等进行了梳理与分析。  相似文献
