Striking a balance: Stakeholder perceptions of risk in horse racing
Abstract Background Thoroughbred racing is a major industry, and in recent years public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

近年来, 我国油田采出的原油中含有大量水分, 油田采出水可以用于回注。但在实际运行中大部分的回注污水水质还达不到低渗油藏注水要求, 致使水井欠注, 影响采油质量。活性炭纤维是一种新型高效吸附材料, 具有独特的孔结构。作者分析了应用活性炭纤维作为精细过滤材料的可行性, 认为其可以改善注水水质, 但存在清洗、成本等问题, 造成其不能在油田回注水处理中的推广应用, 是以后研究中需重点解决的问题。

The modified PSR framework proved valuable for assessing conservation effectiveness and identifying research gaps for waterbirds in the EAAF. Recognizing similar threats to other migratory species globally, we urge action to: (1) prioritize regionally relevant research validating frontline conservation actions, (2) enhance communication between ...

为控制大庆油田注入水中细菌的数量和减少硫化物的危害,作者在油田污水注入站进行了二氧化氯杀菌试验,确定了二氧化氯的最佳投加浓度。结果表明,当储水罐内回注水中投加的二氧化氯质量浓度在40mg/L以上时,对污水中硫酸盐还原菌、腐生菌和铁细菌的灭菌率可达90%,回注水中的硫化物含量也明显减少,细菌与硫化物指标达到油田注水标准。腐蚀率却随着二氧化氯浓度的增大而逐渐增加,最高达到0.069mm/a。在回注水中二氧化氯质量浓度为40mg/L时,腐蚀率达到Q/SYDQ0605-2006企业标准。

A review of 192 articles published between 1985 and 2023 revealed that human–jaguar conflict literature has focused on the human dimensions of conflict, jaguar killings, attacks on domestic animals and humans, and management. Several research gaps remain including: policy enforcement, interdisciplinary research, relevant geographic locations and ...

ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...
