Reduction of sera requirements in amniotic fluid cell culture

Reduction in serum requirement for culture of primary human amniotic fluid cells can be achieved by the addition of 10 growth-promoting factors to the nutrient medium. This supplemented medium preserves cell types normally found in amniotic fluid cell cultures supplemented with 20–30 per cent fetal bovine serum. The volume of amniotic fluid required to initiate culture can be as little as 1 ml. Amniotic fluid samples contaminated with red blood cells with no visible clot also grow well in the low serum medium. Cell-free amniotic fluid combined with equal parts of supplemented medium is useful in initiating cell culture.     

微污染饮用水生物过滤影响因素的研究

通过试验探讨了过滤介质、空床接触时间、水温和反冲洗方式对生物过滤去除有机物的影响。试验结果表明 :活性炭、石英砂组成的双层滤料生物滤池对高锰酸盐指数、UV2 5 4的去除效果比无烟煤、石英砂组成的双层滤料滤池和单层石英砂滤料滤池好 ;在一定的范围内 ,随着接触时间或水温的增加 ,各滤柱对高锰酸盐指数的去除率增加 ;加氯水反冲洗方式对生物滤池去除高锰酸盐指数、UV2 5 4的影响比未加氯水反冲洗方式大     

北极沉积物中硫酸盐还原菌与生物地球化学要素的相关分析

对北极楚科奇海、白令海测区34个沉积物样品的硫酸盐还原菌(SRB)含量与CaCO3、Si、S、P、Cd、Fe、Ti、Pb、Hg等地球化学要素作了相关分析．同时分析了SRB与其所在沉积物粒度与底层水温间的关系．结果表明：SRB与Si、砂及底层水温为正相关；SRB与CaCO3、Fe、Ti、P、Pb、Hg、粉砂、粘土为负相关；而SRB与Cd、S的相关性因海区不同而不同．既有负相关．也有正相关．分析了这些相关状况及其原因．     

CLIMATE CHANGE AND NATURAL HAZARDS IN NORTHERN CANADA: INTEGRATING INDIGENOUS PERSPECTIVES WITH GOVERNMENT POLICY

A study of the relationship between natural hazards and climate change in the international context provides the background for a discussion of the expected changes. In the context of this global discussion, this paper reviews the current perspectives of those natural hazards that are likely to be influenced by climate change, using northern Canada as a regional case study. The northern implications of the United Nations Framework Convention on Climate Change are examined, including the status of climate change action by the northern territorial governments, the evolving role of indigenous people, and the responsibility for climate change impacts. The difficulties surrounding natural hazards research in remote locations, and the approaches of indigenous people to natural hazards are then presented. The paper concludes with a suggested policy approach for climate change and natural hazards in northern Canada, underscoring the need for more comprehensive adaptive strategies to complement the current tendency to focus on the mitigation of greenhouse gases produced in this region.
