The Reality of Contingency: Implications for Crisis Management
Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 3, September 2025.ABSTRACT We live in a time of overwhelming uncertainty. Whether it is the consequences of the 2025 global trade war, the war in Ukraine, the outbreak of new pandemics, the validity of knowledge, or the possible extinction of humans as a species, the power of contingency has never been so profound.

Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective
World Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

Functional Ecology, Volume 39, Issue 8, Page 2149-2169, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants assemble beneficial rhizosphere microbiomes through a ‘cry for help’ mechanism upon pathogen or insect herbivore attack. The arbuscular mycorrhizal fungi (AMF) can influence the composition of microbial communities in the plant rhizosphere. However, their impacts

Journal of Applied Ecology, Volume 62, Issue 8, Page 1889-1901, August 2025.By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

Dianci bileiqi, 2006 参照国家标准并结合防雷经验,针对雷害来源,提出了深圳前湾发电厂主控楼二次系统设备的综合防雷措施。认为,发电厂主控楼防雷首先应根据楼房结构架设一个环行均压等电位接地网;楼房外部防止直击雷应安装接闪器、引下线和接地装置;内部电子设备应安装浪涌保护器（SPD）以降低起源处过电压及过电流。主控室设备的电源及信号系统应安装浪涌保护器及可靠接地;防电磁干扰应安装金属网格屏蔽。采取以上措施后,保证了主控楼的设备安全可靠地运行。

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.Over the past three decades, a large number of natural wild soybean populations have been declining inexplicably or even have disappeared and their distribution area has significantly decreased in China, and population losses continue unabated. Therefore, this study investigated 20 herbaceous communities of wild soybeans in various habitats in ...

Shiyou jixie, 2012 在钻浅层塞作业过程中，为了防止出现井喷顶钻事故，研制了井口防顶装置。该装置是根据以最高上顶力和井口装置最低抗内压两者中最低者来选用井下作业井口控制装置的原则进行设计的。中原油田普遍使用350井口，最高耐压35 MPa，钻塞使用Φ114 mm钻头，故设计的防顶装置承受的最低上顶力为364 kN，附加安全系数1.5倍，其承载上顶力为550 kN，能够避免防顶控制过程中上顶力对防顶装置的损坏，确保施工安全。现场应用控制防顶5口井，成功率100%，有效地解决了钻浅层塞施工中井喷防顶的难题。

Shiyou jixie, 2012 深水钻井防喷器组是保证海洋深水钻井安全的最关键设备。介绍了深水钻井防喷器组的基本配置方法，分析了防喷器组配置的关键因素，重点研究了闸板数量和类型、防喷器高度和压力等级、节流压井管线、蓄能器能力与辅助控制系统等。最后指出，应确保所有剪切闸板具有剪切特定钻杆及套管的能力，测试闸板和管子闸板不可混用，万能防喷器可考虑只采用一个；应确保ROV动作满足规范规定的响应时间要求，不推荐声纳辅助控制系统，应对新增辅助控制系统进行风险分析，以确保设计能兼容并能实现相应的功能；合适的防喷器配置有助于保证深水钻井安全 ...

Zhongguo shiyan zhenduanxue, 2017 随着广谱抗生素在临床上的大量应用,耐甲氧西林金黄色葡萄球菌（MRSA）、产超广谱β-内酰胺酶（ESBLs）的大肠杆菌、肺炎克雷伯杆菌、鲍氏不动杆菌等多重耐药菌（MDRO）引发的医院感染发生率也不断攀升,这些病原菌对多种临床上应用的抗感染药物耐药,给抗感染治疗带来极大的挑战,严重制约了医院感染的防控效果[1,2]。作为重患、急患较多的三甲医院的医生感染防控人员,应建立健全针对MDRO的防控管理制度,做到早期预防 ...

Gaoya dianqi, 2010 提出了一种智能型户外端子箱防凝露控制方法,通过同时采集箱内、外温湿度信息,将两组信息进行智能处理,得出加热器和排风扇的控制条件判定,达到端子箱主动防凝露的目的。研制出了整套智能防凝露试验装置,并在多个变电站进行了长时间的现场试验,获得了良好的效果。与传统的加热除湿装置比较,本装置直接控制箱内露点条件,具备良好温湿度控制曲线和平稳的控制性能;采用低功率远红外加热器配合小排量风扇的控制方式替代目前普遍使用的单一电加热器,除湿快,箱内温升小,加热时间短,节能效果非常显著。
