[目的]两方程模型是RANS工程计算中常用的湍流模型,其中SST k-ω湍流模型具有良好的壁面距离自适应性和逆压梯度流预报能力。然而,湍流模型构造过程中引入的经验性参数使得湍流模型不具普适性,为此,研究采用引入流动控制参数的方法提高湍流模型对船舶流场的适用性。[方法]在经典SST k-ω湍流模型的基础上,GEKO(Generalized k-ω)湍流模型通过引入流动分离参数C_(S)和旋转修正参数C_(RC)分别控制流动分离强度和流动旋转效应,以提高湍流模型对各类流动的适应性。针对JBC船型,采用SURF程序对其流场进行数值模拟并与试验结果进行对比,以考察不同设置下新参数对船体阻力、伴流场和压力分布的影响。[结果]计算结果表明,与经典SST k-ω湍流模型相比,GEKO湍流模型中C_(s)和C_(RC)的设置会影响到JBC船型的阻力预报及伴流场预报。[结论]湍流模型的参数化修正具有提高湍流模型适应性和精确度的潜力,对湍流模型工程应用改进具有参考价值。

Pharmacology & Pharmacy 2020年第1期11卷 9-16页

It is the responsibility of pharmacists to ensure the safety of patients as pharmacist’s professional duties expand into diverse directions. In recent years, the use of automated dispensing systems has increased;however, the inspection by pharmacists is the most important step in the prevention of medical errors. Comparing the inspection of hospital and community pharmacists may lead to an increased awareness of incident countermeasures. Therefore, eye tracking was performed for hospital and community pharmacists who conduct inspection, and the results revealed the factors that affect dispensing errors. One of the factors was the size of the dispensing space, especially if the space was small and the items needed were not easily accessible. In addition, differences in the inspection procedures among pharmacists were presumed to lead to possible dispensing errors due to oversights. Moreover, it was suggested that any subsequent work would flow more smoothly if a pharmacist checked the prescription and medication history management records at the beginning. Furthermore, it was thought that keeping a history of checks, such as recording any prescription checks in writing, would speed up finding the cause in the unlikely event that a dispensing error occurred. Accordingly, creating an environment in which one can concentrate without distractions during the inspections can lead to the prevention of dispensing error.

一般来讲,单独使用一种脱氧剂时脱氧产物认为是纯氧化物。在19届炼钢会议上,日本科学促进协会推荐了每一个脱氧平衡热力学数据。然而,本课题组最新的研究表明,在弱脱氧过程中并不总是形成纯氧化物,并把一些示例列于本论文中。

世界核心医学期刊文摘（胃肠病学分册） 2005年第11期1卷 55-56页

作者： Kitase A. hino K. Furutani T. 李宏宇 Department of Laboratory Sciences Yamaguchi University School of Medicine 1- 1- 1 Minamikogushi Ube 755- 8505 Japan

Background: Oxidative stress contributes to the pathogenesis of chronic hepatitis C. The aim of this study was to assess the peroxidation of n-3 polyunsaturated fatty acids (PUFAs)- in the liver and its relation to hepatic steatosis in chronic hepatitis C. Methods: We immunohistochemically detected malondialdehyde (MDA)- , 4-hydroxy- 2- non-enal (HNE)- , and 4- hydroxy- 2- hexenal (HHE)-pro-tein adducts in liver biopsy specimens from 55 patients with chronic hepatitis C. Cells stained positively for HHE-prot-ein adducts were quantified using computer-based image analysis. Fatty-acid composition was determined, by gas chromatography, for the noncancerous portions of resected livers, with or without steatosis, obtained from two patients with hepatitis C virus-associated hepatocellular carcinoma. Results: The detection rate of HHE-protein adducts (63.6% ) was significantly higher than that of MDA protein adducts (21.8% ; P < 0.001) or HNE-protein adducts (29.1% ; P < 0.001). Areas positively stained for HHE-protein adducts (HHE-positive areas) were significantly larger in 18 patients with steatosis (6.2 ± 3.6% ) than in 17 patients without steatosis (3.4 ± 2.6% ; P = 0.01). Resected liver tissue with steatosis showed a larger HHE-positive area (18.6% ) and higher ratio of n- 6 PUFA content to n- 3 PUFA content (3∶ 1) than liver tissue without steatosis (7.2% ; 2 ∶ 3). On multivariate analysis, the HHE-positive area (odds ratio, 1.55; 95% confidence interval [CI], 1.08- 2.23; P = 0.019) was a factor associated with the presence of hepatic steatosis. Conclusions: HHE-protein adducts, which are a good marker for oxidative stress, are associated with steatosis in chronic hepatitis C.

INTRODUCTION:Pyrolytic-Graphite(PG) is widely used as a high-integrated-reflectivity neutron monochromator. It is a very good monochromator material for moderate-resolution ***,applications such as small-angle neutron scattering(SANS) or reflectometer instruments need a wavelength-band of more than a few%,possibly about 10%.In such cases,not only unreasonably high mosaicity of more than 2 degrees is required,but it must also be coupled with incident beam that has extremely high beam-divergence of about
