静电空气净化消毒器对空气消毒效果的观察

为了观察静电空气净化消毒器对医院室内空气消毒效果,采用平板沉降法采样,对其进行了实验观察并与紫外线作平行比较。结果,经静电空气净化消毒器开机30min后和30W紫外线灯照射60min,均可使空气中自然菌下降率达到88.83％;但室内有人工作的情况下,该空气净化消毒器持续运行可使空气中细菌总数保持在200cfu/m~3以下,符合医院Ⅱ类环境卫生标准,而紫外线则不能。结果显示,静电空气净化消毒器用于医院室内空气消毒,可以在有人条件下持续运行,能保持空气中细菌总数在200cfu/m~3以下。

Dependence of hydropower energy generation on forests in the Amazon Basin at local and regional scales

Tropical rainforest regions have large hydropower generation potential that figures prominently in many nations’ energy growth strategies. Feasibility studies of hydropower plants typically ignore the effect of future deforestation or assume that deforestation will have a positive effect on river discharge and energy generation resulting from declines in evapotranspiration (ET) associated with forest conversion. Forest loss can also reduce river discharge, however, by inhibiting rainfall. We used land use, hydrological, and climate models to examine the local “direct” effects (through changes in ET within the watershed) and the potential regional “indirect” effects (through changes in rainfall) of deforestation on river discharge and energy generation potential for the Belo Monte energy complex, one of the world’s largest hydropower plants that is currently under construction on the Xingu River in the eastern Amazon. In the absence of indirect effects of deforestation, simulated deforestation of 20% and 40% within the Xingu River basin increased discharge by 4–8% and 10–12%, with similar increases in energy generation. When indirect effects were considered, deforestation of the Amazon region inhibited rainfall within the Xingu Basin, counterbalancing declines in ET and decreasing discharge by 6–36%. Under business-as-usual projections of forest loss for 2050 (40%), simulated power generation declined to only 25% of maximum plant output and 60% of the industry’s own projections. Like other energy sources, hydropower plants present large social and environmental costs. Their reliability as energy sources, however, must take into account their dependence on forests.

Acute cataract and optic atrophy after high-voltage electrical injury

High-voltage electrical injuries may result in cataract formation. A patient who developed cataract and optic atrophy of the right eye during the first 2 weeks after injury is presented. The patient did not develop cataract in his left eye. High-voltage electrical injuries may result in cataract formation, and therefore an eye examination should be performed by an experienced ophthalmologist.
