植物油中的色素及吸附脱色研究进展Progress on pigment and adsorption bleaching of vegetable oil
Zhongguo youzhi, 2022 植物油中的色素不仅会影响油脂的色泽，还会降低油脂的品质和贮藏稳定性。脱色过程是去除油脂不良色泽的重要工序，而吸附脱色是油脂企业加工过程中最常用的脱色方法。概述了植物油中色素的来源以及色素的存在对油脂营养和安全性的影响，简要介绍了膜脱色法、光能脱色法、超声辅助脱色法、热脱色法、吸附脱色法等常见的脱色方法，综述了活性白土、活性炭、凹凸棒土（石）、硅胶和复合脱色剂等吸附剂的应用研究进展，总结了吸附脱色目前所存在的问题,如脱色过程中废白土处理率低、深色油脂脱色难，并提出了解决建议（提高废白土中油脂的回收利用 ...

Zhongguo youzhi, 2022 对高酸值米糠油的活性白土与硅胶联合脱色工艺进行研究。对酸值（KOH）为27 mg/g的米糠油进行先活性白土后硅胶脱色，以脱色率、谷维素含量和精炼率为考察指标，在单因素试验的基础上采用响应面试验优化活性白土与硅胶联合脱色条件。结果表明：活性白土脱色最优工艺条件为活性白土添加量25%、脱色时间30 min、脱色温度90 ℃；硅胶脱色最优工艺条件为硅胶添加量2.0%、脱色时间30 min、脱色温度82 ℃。在最优工艺条件下，活性白土脱色后，米糠油脱色率为79.15%，谷维素含量为2.14%，精炼率为90 ...

Zhongguo youzhi, 2023 为对油脂精炼脱色加工提供参考，以活性白土、凹凸棒土以及二者复配作为脱色剂对大豆中和油进行脱色，测定脱色油的酸值、色泽，并通过返酸返色试验探究脱色吸附剂对大豆脱色油返酸返色的影响。结果表明：脱色油酸值与活性白土添加量和复配脱色剂中活性白土质量分数呈正相关，与凹凸棒土添加量呈负相关；脱色剂添加量越多，脱色效果越明显，但在活性白土或凹凸棒土添加量超过3%时，脱色效果增加较少；随活性白土或凹凸棒土添加量的增多，脱色油返酸总体呈先降后升趋势；脱色油会有不同程度的返色，与活性白土相比，凹凸棒土脱色返色程度更高。综上，

International humanitarian narratives of disasters, crises, and Indigeneity
Disasters, Volume 47, Issue 4, Page 913-941, October 2023., 2023 Narratives are a means of making sense of disasters and crises. The humanitarian sector communicates stories widely, encompassing representations of peoples and events. Such communications have been critiqued for misrepresenting and/or silencing the root causes of disasters and crises, depoliticising them.

Veterinary Dermatology, Volume 34, Issue 3, Page 222-234, June 2023., 2023 Background – Mycophenolate mofetil (MMF) is the prodrug of mycophenolic acid (MPA) which acts as an immunosuppressive agent. During the biotransformation of MMF to MPA, additional metabolites including MPA phenol glucuronide (MPAG), MPA acyl glucuronide (AcMPAG) and MPA phenol glucoside (MPG) are formed.

Canine dermatitis on contacting grass leaf: A case series
Veterinary Dermatology, Volume 34, Issue 2, Page 115-124, April 2023., 2023 Background – Pruritus is a common clinical sign in dogs for which owners seek veterinary attention. Its diagnosis and treatment can be a source of frustration for the owner and veterinarian alike. A contact dermatitis is considered rarely, even when lesions are located only on the skin.

Veterinary Dermatology, Volume 33, Issue 6, Page 553-558, December 2022., 2022 Background – Canine flank alopecia (CFA) is characterized by seasonally recurring noninflammatory, occasionally hyperpigmented alopecia predominantly in the thoracolumbar area. Previous studies suggest that reduced production of endogenous melatonin may play a role in the pathogenesis of this condition, and placebo‐controlled studies on the efficacy of

Zhejiang Daxue xuebao. Lixue ban, 2003 以阳离子红X-GRL染料为模型污染物,研究了反应时间、气相氧气流量和水中是否存在溶解氧(DO)等条件对阳离子红X-GRL光降解脱色效果的影响.在缺氧条件下,阳离子红X-GRL染料的光降解脱色效果较差,脱色率仅为9.1%,染料的光降解脱色以光直接降解脱色为主,·OH脱色次之.在有氧条件下,阳离子红X-GRL染料的光降解脱色效果得到显著提高,脱色率由缺氧时的9.1%分别提高到氧气流量为40 L·h-1的27.6%和100L·h-1的38.8%.脱色率的提高主要归因于DO和气相氧气在184.9 ...

Gongye shui chuli, 2006 用还原脱色剂对水溶性偶氮染料进行光还原脱色降解，重点考察了还原脱色剂、辐射光以及染料浓度等对还原脱色反应的影响，并将脱色后的染色废水回用于棉织物染色中。结果表明，以适当比例的引发剂和促进剂组成的还原脱色剂具有较强的脱色降解能力，辐射光对染料的还原脱色反应具有明显的促进作用，染料浓度的提高不利于染料的脱色降解反应。脱色废水可以回用于棉织物的活性染料染色中，通过降低染色过程中氯化钠和碳酸钠的添加量，可使染色试样与自来水染色试样的总色差（DE*）<1.0。
