Effect of Mixed Cooling on Postmortem Energy Metabolism and Meat Quality of Yellow-Feathered Broilers [PDF]
In order to investigate the effect of low-temperature air cooling on the postmortem energy metabolism and meat quality of yellow-feathered broilers during mixed cooling (first water cooling and then air cooling), 85-day-old broilers were slaughtered and ...

Rare Metals, EarlyView.ABSTRACT The development of highly efficient and stable nonprecious metal electrocatalysts for the acidic oxygen evolution reaction (OER) is crucial to advance proton exchange membrane (PEM) water electrolysis. In this work, a dual synergistic strategy was proposed by constructing a Ce‐modified MnO2/MnO heterostructure.

Shuitu Baochi Xuebao, 2019 为了探究夏尔希里自然保护区不同植被类型土壤水源涵养功能特征，在保护区内选取具有代表性的草地、灌木、森林样地共13个，以不同植被类型的土壤为试验材料，采用野外调查与室内试验相结合的方法，分别对保护区内的草地区、灌木区、森林区的土壤水源涵养能力进行定量分析。结果表明：（1）随着土层深度的增加，研究区草地土壤容重逐渐增大，在土壤层0—10 cm处出现最小值为0.69 g/cm3。草地土壤持水能力和蓄水能力变化规律一致，均表现为0—10 cm > 10—20 cm > 20—30 cm。（2）随着土层深度的增加，

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, EarlyView.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...
