Exoautometabolic regulation of transgenes in microorganisms

Data on the existence of a specific system regulating the growth, size, and structure of enterobacterial populations are first summarized in terms of the chemical ecology concept formulated by S.S. Shvarts. The role of this system in transgene functioning is described using the example of the lux operon integrated into Escherichia coli. A relatively simple test for estimating such interactions is proposed.Translated from Ekologiya, No. 2, 2005, pp. 91–96.Original Russian Text Copyright © 2005 by Pshenichnov, Maslennikova, Nikitina.

青藏铁路救援指挥系统的研究

通过对青藏铁路特点及运营模式的分析,提出构建青藏铁路事故救援指挥系统的重要性。结合青藏铁路信息化总体规划,在充分利用青藏铁路各信息系统及通讯网络基础上,利用地理信息系统(GIS)技术和无线通讯技术,建设具有指挥、控制、通信及情报(C3I)功能的青藏铁路事故救援指挥系统。提出了系统应达到的目标功能,结合青藏铁路生产作业实际情况,给出了系统实现的信息流程、体系结构,并开发了原型系统。系统将青藏铁路多源信息整合并结合GIS技术以直观的电子地图、图像等方式展示出来,实现了救援预案管理和智能化查询、匹配;并通过应急无线通讯设备实现事故现场视频、图像实时播放及指挥调度与事故现场间的语音双向通讯;同时可建立事故数据库,为统计报告和事故分析服务。     

Literary and economic impact of the Bhopal gas tragedy

The 1984 Bhopal disaster is widely regarded as a watershed event in the field of process-safety and has been largely responsible for a paradigm shift in the outlook of both industry and the public towards risk management within the processing industries. The Bhopal disaster has led to increased regulations and awareness for process-safety related activities across the globe. This paper reports the effect of the infamous Bhopal incident on the research community and examines the performance of manufacturing industries following the disaster.

For this paper, databases of scientific publications were used to investigate research trends in the safety area following the 1984 Bhopal disaster. Our analysis focuses on prominent safety-related research fields that have emerged following the gas tragedy as well as economic indicators of the processing industries. The study reveals that the process industry has consistently progressed over the years, in spite of added regulations and a worsened public image following the Bhopal disaster, and promises to be a stable economy in the future.     

Ethological farm programs and the “market” for animal welfare

Ethological farm programs as they exist in Switzerland are compared with environmental farm programs in respect of demand and supply. Because animal welfare is not a public good but rather a relation that causes psychological externalities, the demand for animal welfare has a different standing in economic theory than the demand for a clean environment. The supply of animal welfare by farmers, however, largely follows the patterns known from the delivery of environmental goods. Farm size, age and education, and also family size and capital intensity are influencing variables. The paper concludes that the design of ethological farm programs should be based on broad public discussions as described by deliberation theorists rather than willingness-to-pay studies.

微囊藻毒素-LR致肝细胞连接通讯下调的研究

不同剂量(0, 10, 50,100, 200, 500, 1000nmol/L)的微囊藻毒素-LR作用于肝细胞株BRL-3A 24 h.采用激光扫描共焦显微镜,按荧光光漂白后再恢复技术测定BRL-3A的间隙连接细胞间通讯功能,四唑盐法测定BRL-3A细胞增殖,同时分析胆汁酸运输系统抑制剂利福平对两者的阻滞作用.结果表明,微囊藻毒素-LR可以显著地抑制BRL-3A细胞GJIC功能,并促进BRL-3A细胞增殖,两者均呈剂量效应关系.利福平(30靘ol/L)对微囊藻毒素-LR诱导的BRL-3A细胞GJIC功能下调和增殖有明显的抑制作用.微囊藻毒素-LR可诱导BRL-3A细胞膜泡形成.说明微囊藻毒素-LR肝脏毒性及致癌性可能与抑制肝细胞GJIC功能有关.
