A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Design and Implementation of Finance Treasury Centralized Payment System [PDF]
, 2015 财政支付，就是财政对预算单位按照预算编制的批复下达指标，将计划编制到支付、清算的过程整合在一起，进行财政资金支付的过程，财政国库集中支付系统的主体流程就是指标控制计划，计划控制支付的业务管理过程。 为进一步提升财政管理及服务能力，厦门市财政局结合前期无纸化支付建设取得的经验，按照财政部、人民银行制定的统一规范，充分利用现代化金融结算工具和信息技术手段，在财政、人民银行、支付业务代理银行的集中支付系统中构建和部署电子凭证库及相关规范，进行相应的系统改造，基于“对等”、“互通”等原则通过一系列内置的安全规则，

Conservation Biology, EarlyView.Abstract Consumer demand for ivory perpetuates the unsustainable and illegal killing of African elephants and other wildlife species. Interventions that aim to change consumer behavior are increasingly recognized as a crucial element of demand management. However, poor design and implementation have limited their effectiveness.

人为操作因素对酶联免疫吸附法检测乙肝病毒血清标志物影响的探讨
Zhongguo shiyan zhenduanxue, 2010 目的研究探讨在检验日常工作中,人为操作因素对酶联免疫吸附法（ELISA法）检测乙肝病毒(（HBV）血清标志物的影响情况。方法用ELISA法检测HBV血清标志物中具有代表性的表面抗原（HBSAG）及核心抗体（HB-CAB）,对加样后加酶结合物间隔时间、终止反应后延时比色时间、洗板次数、反应温度等四个人为操作条件对结果的影响情况进行分析。结果 HBCAB随着加入样本后再加入酶结合物间隔时间的延长,无论是阴性对照、质控品还是血清样本的吸光度均呈下降趋势,假阳性率增加;HBSAG随着终止反应后比色时间的延长 ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Jianzhu Gangjiegou Jinzhan, 2020 以某两栋办公单体间的长悬臂钢连廊为原型,考虑沿钢连廊长度方向的脉动风速非完全相关性,采用谐波叠加法模拟风速时程,并基于准定常假定进行钢连廊的风振时域分析,得到了结构的风振响应和杆件内力。研究表明:由于该钢连廊的特殊体型,在考虑脉动风速水平向空间相关性后,悬挑端的加速度响应增大明显,并产生了扭转振动;钢连廊的风振系数,尤其是长悬挑部分的风振系数增大效应明显;部分构件的内力增幅明显。因此,在长悬臂钢连廊设计中应考虑风速水平空间相关性对风致效应的影响。
