Efficacy of Selected Compounds on Thermocyclops oblongatus,one of the Main Intermediate Hosts of Guinea Worm in Africa

Ten selected compounds were tested on Thermocyclops oblongatus to determine their ability to be used for treatment of drinking water sources. None were shown to be interesting for individual application in household water tanks. Tested compounds, such as potassium permanganate or chlorine-releasing products, were ineffective or affected dramatically the taste or colour of the water. For collective application in water sources, temephos appeared to be the most valuable pesticide because it was effective against cyclops and harmless for environment. Other pesticides should be proposed as substitutes in case of cyclops resistance to temephos.     

控制网自动平差软件的研制

阐述控制网自动平差软件设计的基本思想,研究了点号的自动最优编排、近似座标的自动推算、变带宽压缩存储等关键算法,据此在微机上设计了一个自动平差软件。该软件能直接处理电子手薄、磁卡和人工手薄记录的数据,用户不需绘制计算略图、编号编码、数据摘录等,处理过程完全自动进行,使平差过程变得非常简单。软件可用于平差导线网约800个点,水准网约2000个点。     

大地热流对中国西部环境与生态演变的影响及其研究意义

中国西部地区生态环境的优劣与大地热流的高低有良好的对应关系。大地热流较高的西南地区生态环境优良,孕育了我国最好的生物多样性;而大地热流较低的西北地区环境恶劣,生态脆弱,荒漠化严重。大地热流的脉动影响区域大气系统下垫面的热力背景和气流运动,从而影响降水的分布和区域气候的干湿程度;大地热流的高低决定了一个地区地表生态系统能量供给的下限,是生态系统演变过程中一个重要的物种限制因子,制约了一些地区生态系统物种的多样性,进而影响到区域生态系统的稳健性。对大地热流影响生态系统发育和演变机理的研究将为人类科学干预地表生态系统的演化、恢复与重建退化生态系统提供科学依据与技术方案。提出了西部生态环境整治的一些新的思路。

Identifying substandard vessels through Port State Control inspections: A new methodology for Concentrated Inspection Campaigns

Substandard vessels that fail to comply with international maritime regulations are the target of Port State Control inspections. Despite their significant costs, many inspections do not lead to any detentions and, in a significant number of cases, no deficiencies are detected. In this paper, quantile regressions for count data are used to estimate the likelihood of having a high number of deficiencies of a specific type. The purpose is to complement existing practices focusing on detention with the objective to improve the selection process. Similar factors influence the likelihood of having a vessel detained and that of having a vessel recording a high number of deficiencies. However, quantile regressions applied to the number of deficiencies help improving the identification of factors influencing the likelihood of finding some specific types of deficiencies, which is the focus of Concentrated Inspection Campaigns. The paper concludes that the selection process for such campaigns should be improved using this new methodology.
