采用直流脉冲磁控溅射的方法,在有机玻璃上沉积了纳米TiO_(2)光学薄膜。研究了沉积功率、基片温度等参数对TiO_(2)薄膜结构及光学性能的影响。借助椭圆偏振光测试仪、X射线光电子能谱仪(XPS)、X射线衍射仪(XRD)、分光光度计、原子力显微镜(AFM)等表征手段分析了薄膜的光学特性、元素组成、结晶性能及显微结构。结果表明:随沉积功率的增加,薄膜氧含量降低,粒径减小,折射率递增,可见光波段的透过率和反射率递减;随基片温度上升,薄膜的沉积速率降低,这促进了薄膜粒子的聚集,在光学方面表现为随温度上升,折射率及可见光透过率同时增加;TiO_(2)薄膜的禁带宽度在3.12~3.16eV之间,随沉积功率增加和基片温度上升,其禁带宽度递减。

少捕慎诉慎押政策下逮捕制度的优化研究

泰山学院学报 2024年第1期46卷 54-62页

作者：苦打哈孙华鑫云南财经大学法政学院云南昆明650000

近年来,由于逮捕要件缺乏客观准确的证明标准、逮捕实践理念有失偏颇、非羁押强制措施运行状况不佳等原因,导致司法实践中逮捕数量较多、逮捕率较高。较高逮捕率不但违背了逮捕作为预防性措施的本质功能,也违背了少捕慎诉慎押政策初衷,... 详细信息

近年来,由于逮捕要件缺乏客观准确的证明标准、逮捕实践理念有失偏颇、非羁押强制措施运行状况不佳等原因,导致司法实践中逮捕数量较多、逮捕率较高。较高逮捕率不但违背了逮捕作为预防性措施的本质功能,也违背了少捕慎诉慎押政策初衷,未能实现打击犯罪与保障人权的有机统一。因此,在少捕慎诉慎押政策下优化逮捕制度,分别从逮捕制度的观念层面、逮捕制度的实质要件层面和逮捕制度配套要件层面提出优化路径。

Introduction: The incidence of acute renal failure (ARF) varies between 20% and 40% of cases for COVID-19 patients admitted to the intensive care unit, with very high mortality, but heterogeneous according to the different epidemic waves, probably due to the genetic variant phenomenon of the virus. The aim of this study is to determine the morbidity and mortality of COVID-19 patients admitted with ARF to the intensive care unit of the Grand H?pital Est Francilien (GHEF) according to the waves and variants. Methods: Cross-sectional observational study of COVID-19 patients with ARF admitted to the intensive care unit of the GHEF site in Meaux covering the period from March 1st 2020 to December, 31st 2021. Per-hospitalisation and outcome data were collected and analysed with SPSS version 25.0 software using the Chi-square or Fischer’s exact test or Student’s t-test and logistic regression for p Results: A total of 86 patients were included. The mean age was higher (70 ± 8.5) in patients in the fourth wave than in the other waves (p = 0.015), with male predominance in all waves without significant difference. Co-morbidities: hypertension, diabetes, heart disease, dyslipidaemia and arrhythmia complete with fibrillation were present in all waves. The majority of patients were classified as KDIGO 1 for the different waves (1st: 61.9%, 2nd: 86.5%, 3rd: 80%, and 4th: 75%), with the same trend according to variant (alpha: 80%, beta: 75%, delta: 81.3%, omicron: 75%). Mortality by the wave was: 1st: 28.5%, 2nd: 37.5%, 3rd: 23% and 4th: 11%) and by variant: alpha: 24.2%, beta: 44.8%, delta: 20.7%, omicron: 10.3%). Overall mortality was 33.7%. Case fatality was higher in the fourth wave. Hypertension, shock, failure to recover renal function, acute lung oedema, ventilator-associated lung disease and hyperkalaemia were factors associated with mortality (p Conclusion: Acute renal failure is common in COVID-19 patients admitted to the intensive care unit, and m
