二氧化钛涂覆材料对甲苯的光催化降解作用

在自制的模拟小室中对二氧化钛涂覆材料的光催化性能进行了初步研究，在玻璃、瓷砖和日光灯这3种常见材料表面涂覆了二氧化钛，并以甲苯为模型化合物，测试了3种材料的净化性能。结果表明，3者对甲苯均有一定的降解效果，是有实用前景的光催化净化材料。     

Prenatal confirmation of trisomy 12 mosaicism by fetal skin biopsy

Trisomy 12 mosaicism diagnosed at 16 weeks' amniocentesis in a 42-year-old woman was not confirmed at 18 weeks' gestational age in amniotic fluid or fetal blood. Fetal skin biopsy performed at the same time did, however, allow the detection of trisomy 12 in 1 of 14 fibroblasts analysed. Fetal skin biopsy can be included within the diagnostic procedures to be performed when a level III mosaicism is found in the amniotic fluid.

印尼8.7级和8.5级强震后江苏体应变同震效应分析

2004年12月26日和2005年3月29日在印尼苏门答腊北部分别发生8.7级和8.5级强烈地震后,对江苏地区前兆体应变资料进行分析发现,在这两次地震的震后都记录到了显著的异常,且异常的表现形式各不相同。本文列出这些异常并浅析,以期对进一步深入研究印尼大震对我国未来地震趋势的影响有所帮助。     

Macroeconomic effects of the recycling of waste derived from imported non-renewable raw materials

The literature on waste recycling neglects the potential effects that this process can have at the aggregate level, although there are positive externalities which have not emerged in the microeconomic analysis of this phenomenon.This paper investigates the macroeconomic effects of the waste recycling process, with particular reference to a country, such as Italy, which uses many foreign non-renewable resources. We use the Keynesian multiplier theory as a theoretical framework to evaluate the potential results of an increase in waste recycling on the gross national product, the balance of payments and employment. In such a way the policy maker can better evaluate whether to promote the process considered here rather than discharging the waste in the environment.     

城市光污染侵害案件法律适用问题的探讨

在城市光污染侵害案件日益增多的同时,我国光污染侵害的法律救济手段和救济结果却不尽人意。虽然我国在宪法、环境保护法等法律、法规及民法中都有处理光污染侵害案件的法律依据,但由于缺少直接的规定,使环境保护法律体系存在太大的缺陷。因此,亟待制定有关的标准和修改相关的法律,从而更好地防治光污染,维护受害人的合法权益。     

Cardiovascular effects of arsenic: clinical and epidemiological findings

Several population studies relate exposure to high levels of arsenic with an increased incidence of ischemic heart disease and cardiovascular mortality. An association has been shown between exposure to high levels of arsenic and cardiovascular risk factors such as hypertension and diabetes mellitus, and vascular damage such as subclinical carotid atherosclerosis. The mechanisms underlying these phenomena are currently being studied and appear to indicate an alteration of vascular function. However, the effects of low levels of exposure to arsenic and their potential detrimental cardiovascular effect are less explored. The article provides an overview of the pathophysiologic mechanisms linking low-level arsenic exposure to the occurrence of cardiovascular disease and its complications, and some potential preventive strategies to implement.
