一、合同的形式概述 合同的形式,又称合同的方式,是当事人合意的表 现形式,是合同内容的外部表现,是合同内容的载体。 从合同法的历史发展看,在合同的形式上明显地表 现出从重形式到重意思的变化规律。这是在交易安全允 许的前提下,适应不断发展的社会经济越来越强烈地要 求交易便捷的结果。当然,重意思不等于完全否定形式。 法律难以评价纯粹内心的意思,只有意思以一定形式表 现出来,能被人们把握和认定时,法律才能准确地评价

当我们伴随着 Windows2000和ASP3.0进入21世纪时,发现微软在企业应用程序开发方面 扩展和改进了对开发人员来说非常有用的工具和技术。在前面两章中讨论了如何使用ASP和 com构建b应用程序。通过使用功能强大的IS,使用所选择的程序语言开发COM组件,使 b应用程序远远超越仅使用ASP脚本创建互相链接的简单网页的水平。可以开发安全高效的 基于组件的可扩展应用程序,以此来支持面向数以千计用户的业务处理

Chapter 6. Laboratory animal facilities Those who use animals for experimental and diagnostic purposes have a moral obligation to take every care to avoid causing them unnecessary pain or suffering. The animals must be provided with comfortable, hygienic housing and adequate wholesome food and water At the end of the experiment they must be dealt with in a humane manner

As aerosols are important sources of infection, care should be taken to reduce the extent of their formation and dispersion Hazardous aerosols can be generated by many laboratory operations, e.g. blending, mixing, grinding, shaking, stirring, sonicating and centrifuging of infectious materials. Even when safe equipment is used, it is best to carry out these operations in an approved biological safety cabinet whenever possible

一、食品的安全性是研究分析食品中可能存在的有害或有毒物质对人的影响,分析食品原料及产品生产,贮藏及加工过程中人为导致的 污染和有害物质的产生,食品添加剂等对人的潜在危害

A basic knowledge of disinfection and sterilization is crucial for biosafety in the laboratory. Since heavily soiled items cannot promptly be disinfected or sterilized, it is equally important to understand the fundamentals of cleaning prior to disinfection (precleaning). In this regard, the following general principles apply to all known classes of microbial pathogens

The Laboratory biosafety manual has in the past focused on traditional biosafety guidance for laboratories. The manual emphasizes the use of good microbiological work practices, appropriate containment equipment, proper facility design, operation and maintenance, and administrative considerations to minimize the risk of worker injury or illness. In following these recommendations, the risk to the environment and surrounding community-at-large is also minimized
