Effects of Oxidized Milk Protein Intaking During Gestation and Lactation on Redox Status in Offspring Mice(孕哺期摄入氧化乳蛋白对子代小鼠机体氧化还原状态的影响) [PDF]
To study the effects of intaking oxidized milk protein with different fat content during pregnancy and lactation on the redox status of offspring mice, the whole milk and low-fat milk were oxidized by heat, then the contents of carbonyl and free thiol ...

厌氧氨氧化是近20 a来逐步发展起来的一种高效、节能新型生物脱氮工艺,其无需消耗碳源且污泥产量低,是处理低碳氮比氨氮废水的较佳选择。对厌氧氨氧化工艺的基本原理、影响厌氧氨氧化细菌活性的常见因素作了简要介绍,阐述了厌氧氨氧化工艺用于污水处理的发展历程,引用部分案例对厌氧氨氧化工艺在低碳氮比废水处理中的应用状况进行了说明,指出其对于低碳氮比高浓度氨氮废水处理效果较好,但对于低碳氮比的中低浓度氨氮废水的处理存在技术瓶颈,即中低浓度氨氮废水难以实现稳定的亚硝化 ...

从生理学、行为学及分子生物学等方面对高原鼠兔(Ochotona curzoniae)的低氧适应机制进行阐述,发现高原鼠兔血液与血红蛋白的结合、释放氧的能力较高,这对低氧时体内氧的传递是有利的;肺小动脉壁变薄,这有利于在低氧条件下进行气体交换,使更多的氧进入肺部,同时高原鼠兔的右心室重量低于常氧环境中的大鼠。这就最大限度防止了高原鼠兔在低氧环境中出现右心室衰竭。行为学研究主要集中在其繁殖行为方面,分子生物学研究主要集中在其血管生成、能量代谢和携氧蛋白的携氧能力方面。

对改良的Carrousel氧化沟活性污泥的氧化还原电位(ORP)变化进行了研究,结果表明,在非严格厌氧状态下磷难以释放,同时ORP也不会降低。在外加有机物且厌氧的条件下,新鲜污泥的ORP会明显降低,一般可以达到-80~-150 mV,且存在显著的磷释放,ORP降低的程度与有机物的浓度和种类无明显关系。微生物活性降低后,外加挥发性脂肪酸,ORP不会显著降低,说明对于EBPR系统来说,ORP的高低取决于微生物厌氧代谢的速率。

Protected areas on international borders show uneven conservation outcomes
Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...

ABSTRACT The heterostructured 1T‐MoS2‐based bimetallic sulfides are promising bifunctional electrocatalysts for alkaline overall water splitting. However, the controllable synthesis of these catalysts is hindered by the ready conversion of Mo species to 2H‐MoS2 and the tedious heterostructure engineering during sulfidation.

在常温下对低碳氮比城市污水进行了短程生物脱氮中试研究。当进水COD为130~210mg/L、m(COD):m(TN)为3.2~4.5、水温19~23℃时,通过控制低氧曝气区的DO为0.2~0.6mg/L,在低氧-好氧(LO)和缺氧-低氧-好氧(ALO)两种工艺中均实现了短程硝化反硝化过程。当HRT为8 h、污泥回流比和内回流比分别为1和2、MLVSS为1 900mg/L时,LO、ALO工艺的TN去除率分别达到64%和74%。

ABSTRACT Atomically thin two‐dimensional (2D) materials have emerged as ideal candidates for realizing high‐density, fast switching, and energy‐efficient memristors. However, ultrathin memristive interlayers, particularly at the atom scale, typically suffer from poor endurance and significant variations.

ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...
