Bibliometric investigation of the integration of animal personality in conservation contexts

open access: yesConservation Biology, Volume 37, Issue 2, April 2023., 2023
Abstract Consistent individual differences in behavior, commonly termed animal personality, are a widespread phenomenon across taxa that have important consequences for fitness, natural selection, and trophic interactions. Animal personality research may prove useful in several conservation contexts, but which contexts remains to be determined.

Enabling conditions for integrating government institutions for disaster risk reduction and climate change adaptation in the SADC region and beyond

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 14, Issue 1, Page 6-26, March 2023., 2023
Abstract Climate change, through extreme weather events, is increasing the risk and impacts of disasters. An increase in extreme weather events underscores the importance of bringing coherence in efforts to reduce the risk of disasters and to adapt to the impacts of the changing climate.

高气压下O2对C4F7N/N2混合气体绝缘性能和分解特性的影响

open access: yesGaoya dianqi, 2021
由于SF6的大量使用对环境产生的影响巨大,因此替代气体的研究受到了广泛关注。C4F7N混合气体具有优良的绝缘性能和环保特性,有望替代SF6作为绝缘介质应用于气体绝缘设备中。为了减少放电过程中产生的有害固体副产物,需要在C4F7N/N2混合气体中加入一定体积分数的O2。文中探究了C4F7N/N2/O2混合气体应用于高气压电气设备的潜力,利用气体绝缘试验平台对0.6 MPa下含不同体积分数氧气的C4F7N/N2/O2混合气体开展击穿试验,同时利用气相色谱质谱联用仪(GC-MS ...

A link between increased temperature and avian body condition in a logged tropical forest

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
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.

Superior Abrasibility of YSZ(ESP)/BN@ZrO2‐Polyester Composite Sealing Coating Reinforcing With Hybrid Micron/Nanometer Multiscaled Pore Structure

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Deconstructing Masculinity: A Mixed‐Methods Exploration of Health Access and Legal Implications Among Middle‐Aged Men in Yaoundé, Cameroon

open access: yesSexuality, Gender &Policy, Volume 9, Issue 2, May 2026.
ABSTRACT Masculinity significantly influences men's health‐seeking behaviors, yet its intersection with legal frameworks and healthcare access in Sub‐Saharan Africa remains underexplored. This mixed‐methods study investigates how gender norms and structural barriers influence healthcare experiences among 60 middle‐aged men (aged 30–60 years) in Yaoundé,

Hybrid Flame‐Assisted Plasma‐Enhanced Chemical Vapor Deposition Strategy for Scalable and Structurally Tunable ZrO2 Thin Films

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Zirconium dioxide (ZrO2) thin films are critical materials owing to their thermal stability, mechanical durability, and optical transparency enabling applications in photonic, sensing, and electronic devices. However, achieving uniform deposition via plasma‐enhanced chemical vapor deposition (PE‐CVD) has remained challenging due to poor ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

550kV SF6/N2充气母线绝缘性能研究

open access: yesGaoya dianqi, 2014
由于SF6气体的温室效应,减少SF6气体的使用具有深远的社会意义,用SF6/N2混合气体取代纯SF6气体作为高压电器设备的绝缘介质是减少使用SF6气体的有效措施。介绍了SF6/N2混合气体的优点。从气体放电理论出发,对不同比例SF6/N2混合气体的绝缘性能进行了分析,结果表明:SF6体积分数仅为20%的SF6/N2混合气体击穿强度为相同气体压力纯SF6的70%左右;若SF6体积分数为20%的SF6/N2混合气体的击穿强度要达到纯SF6气体的击穿强度,其总压力应为纯SF6气体的1.4倍 ...
