电厂山区性河流取水工程安全设计分析

通过对代表性山区河流电厂的取水工程安全实例分析 ,根据取水方式不同 ,建议应采取的措施分为 :直接在天然河道上布置取水构筑物时 ,取水头部上下端加设三角形挡沙板 ,取水口上游设导沙丁坝 ,抬高取水头高程和进水底槛高程 ,并且可考虑设置两套取水系统 ,枯水期直接利用河道取水头取水 ,洪水期从移动式泵车取水 ;在河道上设置拦河低坝取水时 ,必须设置配套取水防沙设施 ,如排沙闸或冲沙闸 ,进水闸前设导沙坝 ,冲刷闸前设导沙坎 ,泄洪闸前设冲沙廊道和导流堤 ,还可在河道上设置潜水丁坝等。     

A survey on occupational accidents’ reporting and registration systems in the European Union

This paper presents the results of a survey on the procedures for reporting occupational accidents in the EU countries. It focuses particularly on the reporting and registration systems, as well as on the main characteristics of National Databases being used for the production of official statistics. The survey shows that many European countries have different methods and procedures for collecting and compiling data on occupational accidents, which inevitably pose problems when comparing accident statistics between the EU member states.The paper includes a brief review of the main goals and achievements of the European Project ESAW (European Statistics on Accidents at Work), which was launched in 1990 by the Eurostat (European Statistics), for the harmonisation of occupational accidents’ statistics among the member states. It is believed that the new variables being introduced by the harmonised methodology will quickly affect the way in which managers and insurance companies carry out their current procedures in several EU member states.The International Labour Organisation (ILO) recommendations and the future trends are also analysed. In conclusion, the study identifies opportunities for further development and research in the reporting and registration systems of occupational accidents.     

浅埋型矿井涌水量预测预报的灰色模型

矿井涌水量预测 ,对矿井安全及正常生产都至关重要。矿井涌水量预测采用的常规方法对各含水层的水文地质参数依赖性较大 ,而对各因素之间的影响程度难以区分和把握 ,因此 ,在预测预报中的精度较差 ;而采用灰色理论则具有高度的概括性 ,可以把各种不确定因素 ,统统用一个简单的“灰数”来表示 ,并且预测精度高而简单实用。笔者在分析浅埋型矿井涌水量的构成要素的基础上应用灰色系统理论对其涌水量进行了预测 ,其方法与结果对推动矿井水文地质工作有一定的现实意义和指导作用。

Juvenile Dispersal in the Colonies of Spermophilus majorand S. suslicus Ground Squirrels

Natural dispersal of young animals was studied in the colonies of Spermophilus major and S. suslicus ground squirrels in the Volga region. On the basis of data obtained, this process was modeled taking into account the spatial–ethological structure of the colonies. In both species, male dispersal was more active, whereas the degree of natal philopatry was higher in females. The results of the study do not confirm the aggression concept of juvenile dispersal and indicate that its causes are related to hereditary behavioral tendencies. These results are compared with data on juvenile dispersal in other species of the genus Spermophilus.     

Women, Health and Humanitarian Aid in Conflict

The burden of political conflict on civilian populations has increased significantly over the last few decades. Increasingly, the provision of resources and services to these populations is coming under scrutiny; we highlight here the limited attention to gender in their provision. Women and men have different exposures to situations that affect health and access to health-care and have differential power to influence decisions regarding the provision of health services. We argue that the role of women in planning is central to the provision of effective, efficient and sensitive health-care to conflict-affected populations.
