High Voltage, EarlyView.ABSTRACT Dissolved gas analysis (DGA), widely used for fault diagnosis, can be significantly influenced by the presence of oxygen. Oxygen not only accelerates fluid degradation but also alters the type and concentration of fault gases generated, potentially leading to misinterpretation of transformer conditions if conventional DGA models are applied ...

Volatile Compounds in Feathers of the Scarlet Macaw (Ara macao) Reflect Sex and Pair‐Bond Status
Integrative Zoology, EarlyView.Scarlet macaws exhibit sex‐ and pair‐related differences in plumage volatile composition, with males showing greater chemical richness. Partnered individuals differ in specific compound classes, whereas no clear association with immune function was detected. These results support a potential role for olfactory cues in sexual and social communication in

大豆油水酶法提取技术研究进展Research progress on aqueous enzymatic extraction technology of soybean oil
Zhongguo youzhi大豆油是我国居民膳食油的主要来源，富含多种营养成分。为促进大豆油提取技术的发展，从水酶法提油的基本原理出发，重点阐述了大豆油水酶法提取技术中酶的筛选和活性优化、酶解工艺优化、酶解后破乳以及水酶法与其他辅助手段联用的研究进展，同时综述了水酶法提取对大豆油品质的影响。相比于其他油料，大豆含油量较低且胞内存在占比较大的蛋白质使得其油脂提取较困难。通过工艺优化可有效提高水酶法提取大豆油的提取率，且所得油脂营养价值相对较高，水酶法提取条件温和、能耗低、操作简单安全，符合大豆油加工业的发展需求 ...

Seasonal variation in preen gland secretions of Tristram's Storm Petrel (Hydrobates tristrami)
Ibis, EarlyView.Preen gland secretions are known to vary depending on sex, season and species and are thought to play essential roles in avian life history. However, their chemical composition and functions remain largely unclear in Procellariiform seabirds with well‐developed olfactory senses. Storm petrels, known for their distinctive body odour, may use preen gland
