脓肾合并应激性高血糖患者血糖变异性与肾功能及临床预后的相关性
Zhongguo shiyan zhenduanxue, 2016 目的探讨脓肾合并应激性高血糖患者血糖变异性与肾功能及临床预后的相关性。方法将我院收治的脓肾合并应激性高血糖患者根据24h血糖波动均值（GM）及血糖波动系数（GV）四分位间距从低到高分为Ⅰ组、Ⅱ组、Ⅲ组、Ⅳ组和A组、B组、C组、D组,记录不同分组APACHEⅡ评分、肾实质厚度、肾内动脉血流阻力指数、低血糖事件及脓毒血症发生率,分析GM与GV值以及二者与APACHEⅡ评分、肾功能及脓毒症发生的相关性。结果随着GM值、GV值的升高,患者APACHEⅡ评分、RI值以及脓毒症发生率均随之升高,肾实质厚度逐渐减小 ...

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Dianci bileiqi, 2014 针对多级电涌保护器（SPD）安装在电源线路时可能对负载电压起到抑制作用,而导致SPD达不到预期的有效性保护的问题,通过组合波发生器（1.2/50μs、8/20μs）模拟雷电流,对负载分别为阻性、容性、感性时,特性阻抗值相同、长度不同的RVVP电缆做冲击试验,研究负载与RVVP电缆特性阻抗匹配关系及波电缆中的折反射现象,分析电缆的长度与不同特性负载的关系,得出当负载为阻性时,多级电涌保护器的有效防护距离与电阻值呈负相关;当负载为容性时,多级电涌保护器的有效防护距离与电容值呈先负相关后正相关;当负载为感性时,

Defining and identifying relevant stakeholders to advance effective conservation
Conservation Biology, EarlyView.The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty
Conservation Biology, EarlyView.Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...
