苏联水资源的保护与综合利用

合理利用自然和保护环境不受污染,作为重要任务,已列入苏共第二十五大决议中。在《苏联1976—1980年国民经济基本发展方向》中具体规定了综合合理利用和保护土地资源、水资源和森林资源的各项措施。据报道,这些措施正在顺利贯彻执行中。本文着重介绍苏联工农业生产的水资源综合利用和保护的具体措施。     

二氧化硅粉末防治谷蠹的效果及其影响因素

前言 造成谷物损失的仓虫危害是储粮中最严重的问题(Jilani等,1990;Sigamony等,1986)。30多年来,人们广泛使用低剂量的合成杀虫剂防治储粮害虫(Redlinger等,1988),但是,许多储粮害虫已对这些杀虫剂产生了抗性(Champ等,1976;Parkin,1965;Redlinger等,1988;     

Pursuing Sustainable Development： A Comment on China as the Largest Foreign Investment Recipient

This paper examines the role of foreign investment in China with particular focus on its implications for environment. It shows that most of investments generate both positive and negative effects on China＇s environment. Many of these projects are located in the so-called pollution-intensive industries. This paper tries to elaborate the existing greater environmental implications by the foreign investments. It is concluded that only by honestly evaluating the environmental and social impact of liberalizing trade and investment can China determine whether expand or contract foreign capital utilization for further development.     

Quality issues in health care research and practice

The Institute of Medicine's comprehensive program for quality improvement is based on many years of data observation, collection, and analysis. This work was performed by practitioner-researchers and efficiency consultants from many disciplines. The resulting recommendations are striking in their straightforward practicality and in their insistence that process factors determine output. According to Leape and colleagues (1991) "most adverse events are preventable...particularly those due to error or negligence." Leape et al. (1991) note that in industry, "an error rate that exceeds defined norms is deemed unacceptable" and urge that similar norms apply in medicine. As knowledge and technology improve, the results of quality undertakings are certain to foster health care's development into an endeavor in which errors are becoming increasingly rare events.     

The next 20 years: how customer and workforce attitudes will evolve

Business projects with very long time horizons--such as those involving product R&D, workplace design, and total compensation planning--have to contend with a crucial question: What will be the needs, demands, and desires of consumers and employees decades from now? If you think the answer is "Just more of the same," you're in for a surprise. Howe and Strauss, the authors of Generations, The Fourth Turning, Millennials Rising, and other books, have studied the differences among generations for some 30 years. Their extensive research has revealed a fascinating pattern--one so strong that it supports a measure of predictability. On the basis of historical precedent, they say, we can foresee how the generations that are alive today will think and act in decades to come. Three of those generations will still be vital forces in American society 20 years from now: Boomers, Generation X, and Millennials. Their attitudes and behaviors will have profound effects on the economy, the workplace, and social institutions in general. For example, as aging Boomers eschew high-tech medicine in favor of holistic self-care, natural foods, and mind-body healing techniques, some hospitals are opening new wings featuring alternative medicine and spiritual counseling. Gen Xers, having grown up in an era of failing schools and marriages, will remain alienated, disaffected, and pragmatic as they enter midlife. Already the greatest entrepreneurial generation in U.S. history, they will be highly effective at pushing innovation, efficiency, and mass customization. In contrast, young adult Millennials will favor teamwork, close family relationships, job security, and a bland popular culture. Their unprecedented digital empowerment and talent for organizing will create a political powerhouse and may even revitalize the union movement.     

地质岩心钻探泥浆专家系统的设计

目前,对于地质岩心钻探泥浆使用技术的要求对矿业的发展来说十分的重要。但是在其专家系统的设计上存在很大的不足,文章就针对地层分类以及工程实例为标准的泥浆配方推论模式对专家系统中的数据信息资源、配方的数据库、材料数据库进行专业的设计,通过设计后的系统软件能够根据不同的地质钻探工程、地层信息等对矿业的发展做出统计,同时能够利用软件系统查询泥浆材料的说明、使用情况、生产的具体信息等资料,对矿业现场施工的发展有良好的帮助。
