| 1 | Influence of bed elevation discordance on flow patterns and head losses in an open-channel confluence显示文摘Confluences play a major role in the dynamics of networks of natural and man-made open channels, and field measurements on river confluences reveal that discordance in bed elevation is common.Studies of schematized confluences with a step at the interface between the tributary and the main channel bed reveal that bed elevation discordance is an important additional control for the confluence hydrodynamics.This study aimed to improve understanding of the influence of bed elevation discordance on the flow patterns and head losses in a right-angled confluence of an open channel with rectangular cross-sections.A large eddy simulation (LES)-based numerical model was set up and validated with experiments by others.Four configurations with different bed discordance ratios were investigated.The results confirm that, with increasing bed elevation discordance, the tributary streamlines at the confluence interface deviate less from the geometrical confluence angle, the extent of the recirculation zone (RZ) gets smaller, the ratio of the water depth upstream to that downstream of the confluence decreases, and the water level depression reduces.The bed elevation discordance also leads to the development of a large-scale structure in the lee of the step.Despite the appearance of the large-scale structure, the reduced extent of the RZ and associated changes in flow deflection/contraction reduce total head losses experienced by the main channel with an increase of the bed discordance ratio.It turns out that bed elevation discordance converts the lateral momentum from the tributary to streamwise momentum in the main channel more efficiently. | Pedro Xavier Ramos Laurent Schindfessel Joao Pedro Pego Tom De Mulder | 2019 | Water Science and Engineering2019，12，3： | 3 |
| 2 | 低渗核黄素在圆锥角膜患者角膜交联术中的应用(英文)显示文摘目的:比较圆锥角膜患者角膜交联(CXL)、等渗(IR)和低渗核黄素(HR)的结果。方法:回顾性研究,包括29例29眼圆锥角膜患者行角膜交联术,IR组15眼,HR组14眼。参数分析包括(随访1a):最佳矫正视力(BCVA),球体和柱体,中央和较薄处角膜厚度,平均和最大角膜曲率(分别为Km和Kmax),并发症及进展。结果:观察到两组的BCVA提高:治疗前IR组为0.26±0.57,HR组为0.47±0.72。术后1a,IR组为0.13±0.79,HR组为0.29±1.52,IR组BCVA更高(P=0.018)。术后1mo,两组中央角膜厚度(μm)均减少,但在接下来的数月中增加:术前IR组为497±28μm,HR组为432±14μm;术后1a,IR组为480±31μm,HR组为424±15μm。较薄处角膜厚度也是如此,术前IR组为487±29μm,HR组为410±20μm;术后1a,IR组为468±33μm,HR组为413±13μm。两组中Km和Kmax均降低。每组6眼呈现短暂的混浊,无持续性混浊。结论:在中央角膜厚度<400μm的患者中,HR的使用似乎是一个有效的替代执行传统CXL的技术。 | Ana Sofia Lopes Diana Silva Susana Henriques Peter Pego Cristina Vendrell Isabel Prieto | 2020 | 国际眼科杂志2020，20，2： | 2 |
