全自动血培养瓶的再利用实验评价

目的 评价全自动血培养瓶的再利用实验。方法 研制高营养快速细菌培养基,并将其应用于全自动血培养仪进行再利用实验,分析阳性率、阳性检出时间和检出菌的种类。结果 经32例全自动血培养再利用实验,平均阳性检出时间在再利用血培养瓶与仪器对照组之间无显著的差异(P<0.05)。608例再利用血培养分离到78株细菌,阳性率12.9％,24 h内检出的阳性占64.1％,48 h内检出的阳性占87.2％,72h内检出的阳性占96.2％。结论 临床应用全自动血培养瓶的再利用实验可提高血培养阳性率,缩短检测时间,减少污染机会,结果快速、准确。

凸透镜成像规律教学初探

在实验基础上,师生进行共同分析、讨论.教师可以提问:在蜡烛向凸透镜靠近时(物距变小),像的大小发生了如何变化?(由小到大最后在光屏上没有像)像能由小变大,那么是在逐渐变大的吗?中间由大小相同的吗?这点在那里?此时再让学生重做实验,找出U=2f这个点.U=f点的寻找:最后光屏上没有了像。

Decommissioning of Uranium Pilot Plants at IPEN-CNEN/SP： Facilities Dismantling, Decontamination and Reuse as New Laboratories for Strategic Programs

From beginning of 90＇s, the Brazilian nuclear policy has been changed radically. This determined the interruption of most R＆D fuel cycle activities and the facilities shutdown at Nuclear and Energetic Research Institute （IPEN）. The existence of those facilities also implicated in the need of constant surveillance, representing additional obligations, costs and problems. The reasons to promote the dismantling of the IPEN＇s Nuclear Fuel Cycle Pilot Plants elapsed mainly from the need of physical space for new activities, since the R＆D in the nuclear fuel cycle area were interrupted. In the last decade, IPEN has changed its ＂nuclear profile＂ to a ＂comprehensive and multidisciplinary profile＂. With the end of most nuclear fuel cycle activities, the former facilities were distributed in four different centers. Each center has adopted a different strategy and priority to face the D＆D problem. The available resources depend on the specific program in each area＇s development （resources available from other sources, not only from Brazilian National Nuclear Energy Commission （CNEN）. One of those new activities is the IPEN＇s Environmental Program. This paper describes the procedures, problems faced and results related to the reintegration of the former pilot plant areas as new laboratories of the Chemical and Environmental Technology Center-CQMA of the IPEN.

清料法皮蛋料液的循环利用研究

为提高清料法皮蛋生产中料液的利用率,降低生产成本及其对环境的污染,通过对清料料液中的多种辅料进行补充,建立了浸料法加工皮蛋工艺中回笼料再利用方法。结果表明:使用过的皮蛋加工料液.可以进行再利用,从而降低了成本,提高了产品的利润,方法简单易行,适合工厂车间操作,为将皮蛋加工过程中产生的回笼料作为资源再利用提供了新的途径。
