Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

Applicability and Structure Optimization of Cyclone Separator Based on Numerical Simulation [PDF]
, 2015 旋风分离器是一种利用气-固两相流体的涡旋运动使固体颗粒在离心力的作用下从气流中分离出来的设备，它具有结构简单、操作维护简便、制造安装价格低等优点，被广泛应用于石油、化工、冶金等领域。由于其内部流场具有强旋流湍流特征，气流和颗粒的运动十分复杂，传统的实验方法很难深入研究其内部流场规律和分离机理，随着计算流体动力学的发展，数值仿真分析成为研究旋风分离器的主要手段。 旋风分离器的工况和结构参数会对其性能产生决定性影响。对于一个给定的旋风分离器，其工况参数包括颗粒半径、颗粒密度和入口速度 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.
