This study aims to evaluate the biosafety awareness of laboratory staff working on pathogens detection in seven Centers for Disease Control and Prevention and support these staff\'s biosafety management and training. A total of 208 laboratory staff from seven provincial CDCs were chosen by stratified random sampling to undergo a self-administered questionnaire survey. The collected data were analyzed using SPSS 22.0. The overall average biosafety awareness of the CDC laboratory staff involved in pathogen detection was 82.5 points. The average biosafety awareness score was the highest in health monitoring (92.63 points) and the lowest in risk assessment and control (41.6 points). Among the seven provincial CDCs, the Guizhou Provincial Center for Disease Control and Prevention laboratory staff showed the lowest average biosafety awareness score (74.3 points). The team who worked for 5-14 years were more likely to score above the passing score (≥88 points; corrected OR 0.400, 95%CI: 0.168-0.951) than the staff with less than five years of work experience. In addition, the mid-level and junior-level staff, as well as the lower position ones were more likely to score below the passing score (<88 points; junior level and lower: corrected OR 3.473, 95%CI: 1.028-11.737; mid-level: corrected OR 2.797, 95%CI: 1.027-7.618) compared with the senior-level staff. Among the surveyed team, 66.3% identified a lack of specific funds related to work, 61.5% identified a lack of designated personnel for the laboratory biosafety management. The biosafety awareness in CDC laboratory staff involved in pathogen detection is low, especially regarding risk assessment and control. The biosafety awareness in Guizhou and Guangxi Provincial CDC laboratory staff is also low. Laboratory funding, job title, and years of experience in a laboratory influence biosafety awareness in CDC laboratory staff. The biosafety knowledge, education, and training of CDC laboratory staff involved in pathogen detection need to improve by paying attention to the content and coverage of biosafety training, exploring new training modalities, and increasing funding for activities related to biosafety in CDC.“,”This study aims to evaluate the biosafety awareness of laboratory staff working on pathogens detection in seven Centers for Disease Control and Prevention and support these staff\'s biosafety management and training.

木乃伊(Mummy)一词源自波斯语Mumiai,是指在物理或化学机制下软组织得以保存的生物遗骸.作为考古学研究的一大主题,木乃伊已被证明含有大量生物医学和生物人类学信息,研究人员可以利用生物学、医学手段从遗骸中将其恢复,具有独特的研究价值.木乃伊具有如下特点:首先,软组织与骨骼得以完整保存,这为生前所患疾病、死亡原因的诊断以及进一步探讨人群健康状况、行为习惯和疾病的演变提供了证据;同时,木乃伊中保存有较好的DNA和同位素信息,对这些信息的提取和分析可以探索人类进化、迁徙路线和饮食结构等问题.

精炼过程中进行钢包吹氩是一种去除钢中夹杂,提升其洁净度的重要手段.为快速且低成本地捕获最佳吹氩流量,通过流体分析软件FLUENT对钢包偏心底吹氩过程进行数值模拟.结果表明:在合适的吹气量下,气流会随着吹气时间的延长,在钢液中形成一个闭合的循环区域;吹气量从10?Nm3/h增大到30?Nm3/h,气流的平均动能和平均速度显著增大,死区比例则从21%下降到6%;当吹气量超过临界值30?Nm3/h时,进一步加大吹气量,死区比例趋于稳定,氩气利用率降低;吹气量为30?Nm3/h时达到最佳吹气量,此时钢液中的流体能

路径跟踪精度是实现叉车式AGV工程应用的关键参数之一.常见的基于趋近律的滑模控制方法不能适应复杂工况的应用需要而且容易产生抖振.为此,文章提出了一种基于幂次趋近律和反正弦函数构成的新型趋近律的滑模控制方法,以实现对叉车式AGV的路径跟踪控制.通过MATLAB软件进行了仿真实验,并进行了原型车实物测试,仿真和实物测试结果表明,所提出的控制方式不仅可以提高叉车式AGV的跟踪精度,而且降低了叉车式AGV运动中产生的抖振.
热稳定性是功能蛋白(特别是酶蛋白)储存和使用的重要限制因子.许多商业酶因耐热性不能达到工业生产的热处理条件而无法被采用;另外,植物中与光合作用有关的关键酶也受高温抑制,从而导致农作物产量下降.因此,对酶蛋白进行分子改良以提高其热稳定性,进而提升其功效和扩大其应用范围,具有重要的现实意义.选取3种典型的热稳定性差、易聚集但具有重要功能的酶蛋白(小桐子抗坏血酸过氧化物酶1即JcAPX1、大肠杆菌高丝氨酸-O-转琥珀酰酶即EcMetA、假单胞菌亚磷酸盐脱氢酶即PsPtxD)作为靶蛋白,鉴定出超嗜热菌Pyroco
