解除管制的电力工业对水轮机运行稳定性的要求在不断提高，然而，对空化状态下运行的复杂物理现象却了解甚少。本文描述了一个实验研究，其目的是使人们对此问题有一个更深入的了解。由于2D NACA 0015翼型曾被世界上几个研究者使用过，所以本实验选择了此翼型作为研究对象，实验在两个不同的水洞中进行，对不同比尺的翼型进行研究，一个水洞是美国的Saint anthony Falls实验室（SAFL），另一个水洞是德国Obrnach的Versuchsanstalt fuer Wasserbau(VFW)（水利工程研究院）的实验室，两个实验在设计上既具有互补性又能体现出各自的特点。实验工作由Charles Song教授针对相同布置进行了数值分析。模拟方法是基于大涡流模拟技术（LeS），利用正压相模型结合连续性方程及动量方程进行的。

文章简介进行性核上性麻痹(Progressive Supranuclear Palsy,PSP)是一种以Tau蛋白异常聚集和缠结为特征的运动障碍疾病。迄今为止人们对该疾病的致病机制知之甚少。之前的研究发现单核苷酸突变(SNP)(rs1768208 C/T)是PSP发病的高风险因子。本研究通过对正常人和PSP患者的大脑样品进行检测,发现rs1768208 C/T中高的T等位基因频率与促凋亡蛋白appoptosin水平增高相关联,而appoptosin水平的增高与caspase-3的激活及caspase对tau蛋白的剪切相关。

Background: Postpartum inflammation is a natural and necessary response;however, a dysfunctional inflammatory response can be detrimental to animal productivity. The objective of this study was to determine the effects of a non-steroidal anti-inflammatory drug(meloxicam) on ewe postpartum inflammatory response, ewe plasma polyunsaturated fatty acid and oxylipid concentrations, and lamb ***: After lambing, 36 Hampshire and Hampshire × Suffolk ewes were sequentially assigned within type of birth to control(n = 17) or meloxicam orally administered on d 1 and 4 of lactation(MeL;90 mg, n = 19). Milk and blood samples were collected on d 1(prior to treatment) and d 4. Milk glucose-6-phosphate was not affected by MeL. Plasma haptoglobin(Hp) concentrations were less for MeL ewes;control ewes with greater d 1 Hp concentrations had elevated Hp on d 4, but this was not the case for MeL-treated ewes. Treatment with MeL increased plasma arachidonic acid concentration by more than 4-fold in ewes rearing singles but decreased concentrations of 9,10-dihydroxyoctadecenoic acid, prostaglandin F2α, 8-iso-prostaglandin e2, and 8,9-dihydroxyeicosatetraenoic acid. Nine oxylipids in plasma had interactions of treatment with d 1 Hp concentration,all of which revealed positive associations between d 1 Hp and d 4 oxylipid concentrations for CON, but neutral or negative relationships for MeL. MeL decreased 13-hydroxyoctadecadienoic acid:13-oxooctadecadienoic acid ratio and tended to increase 9-hydroxyoctadecadienoic acid:9-oxooctadecadienoic acid ratio(both dependent on d 1 values), indicating progressive metabolism of linoleic acid-derived oxylipids occurred by enzymatic oxidation after MeL treatment. Meloxicam reduced oxylipids generated across oxygenation pathways, potentially due to an improved redox ***: Postpartum MeL treatment of ewes decreased plasma concentrations of Hp and several oxylipids,with the greatest impact in ewes with biomarkers reflecting a greate
