背景:阑尾切除术是一个切除阑尾的外科手术,阑尾大约6英寸长或者更短,是大肠的分支。有两种方法来执行这个手术分别是开腹和腹腔镜。在微创手术过后,腹腔镜手术的并发症发生率在多年来持续减少。腹腔镜阑尾切除术尚未被一致认为是治疗急性阑尾炎的第一首选,由于其较长的手术时间,手术时腹腔脓肿的风险,并且成本要比开腹阑尾切除术。另一种方法是开腹切除。外科医生定位阑尾并通过切口切除阑尾。与任何外科手术一样,都有可能发生并发症。本文的主要目的是定性地回顾最近在复杂的阑尾炎中进行的腹腔镜手术和开腹手术的随机对照试验。本论文还将详细介绍这两个程序的优点和缺点以及复杂性,使读者对这两种程序有全面的了解。根据大量的研究以及发表的文章和期刊表明,这两种手术都是具有多重优势以及常见的,并且是积极的结果,两者仍然具有并发症的风险,而且有着让人不满意的美容效果的缺点。目的:本论文的主要目的是对两个最近进行的随机对照试验进行了系统的回顾性分析,并得出结论方法:自从2006年开始到2016年为止,从多个在线可用的数据库进行搜索,两个rct采用开腹与腹腔镜阑尾切除术及复杂性阑尾炎的相关术语,在数据库pubmed,cochrane和embase。rct在纳入和排除标准之后可以免费以及公共观看的。这两个rct曾通过jadad评分系统的审查和评分,进行递归抽取,并且将两个实验缩减至总结版本。prisma图证明了搜索随机对照实验的过程,以及总结。没有使用软件并使用笔和纸进行审查。还应注意的是,试验不再是免费的,thomson的试验报告可在“researchgate”免费获得,但taguchi的试验不再可用,必须购买且在本研究期间均可用。meta分析没有进行,本系统综述以叙述形式提供。还有许多其他研究以同样的方式进行,否则被称为只是系统的审查或实证研究定性分析。结果:从众多的研究和发表的文章缩小到了只有2项2014和2015年施行了,本文只涉及在复杂的情况下的随机对照试验,在thomson2014年的试验中有提到过,这是有史以来第一个rct针对la和oa。本次审查的重点是手术时间,转换率,术后住院时间,并发症,发病率和恢复到正常活动。这项审查也以定性的方式系统地分析了这两个试验。结论:通过仔细分析递归抽象的数据提取和通过JADAD的试验进行分级后,显然可以说腹腔镜手术治疗复杂阑尾炎是安全和可行的,但没有发现任何腹腔镜超过开腹式的特征。

OBJECTIVE: To evaluate the effect of Persian shallot extract on the serum markers and blood pressure of patients with metabolic syndrome(MetS). METHODS: Fifty patients with Met S diagnosis were randomly assigned to the intervention(Persian shallot extract) and the control(placebo) group. Both groups received treatment for three months. Before the study and at the end of the study, 5 mL peripheral blood was taken from each patient. The measured factors included total antioxidant capacity(TAC), superoxide dismutase enzyme(SOD), malondialdehyde, oxidized low-density lipoprotein(Ox-LDL), apolipoprotein H(Apo-H), fasting blood glucose(FBS), total cholesterol, triglycerides, high-density lipoprotein(HDL), LDL, and systolic and diastolic blood pressure. RESULTS: At baseline, the evaluated parameters were not significantly different between the intervention and control groups. At the end of the study, the mean serum levels of malondialdehyde and ox-LDL were significantly lower in the intervention group. The mean FBS, cholesterol, triglycerides, and LDL were significantly lower in the intervention group. The mean TAC and HDL were significantly higher in the intervention group(P < 0.05). Moreover, the intervention group significantly reduced systolic and diastolic blood pressure. No other significant association was observed. CONCLUSION: Persian shallot extract has several beneficial effects in Met S patients, including optimizing oxidative balance, reducing blood pressure, fasting blood sugar, and blood lipid profile.

Wheat is a strategic crop for food security in Pakistan with predominance of smallholder farmers. Farmer-saved seed （FSS） is used nearly by 75% of farmers for wheat production. Frequent variety or seed replacement is uncommon even among large-scale farmers, and certified seed （CS） is mostly bought to verify the value of new varieties. Replacing old and obsolete varieties by new high yielding disease resistant varieties is key to transferring new genetic gains to farmers. For the first time in Pakistan, on-farm factorial experiments involving seven new and five old wheat varieties and their corresponding CS and FSS were conducted. A total of 49 farmers representing major wheat cropping patterns throughout the country participated in these trials in the 2014 and 2015 wheat growing seasons. Analysis of variance revealed that there was highly significant difference between wheat varieties and between seed classes. New variety ＋ CS gave 33.8% more grain yield as well as higher marginal return over farmers＇ variety ＋ FSS. Grain yield and returns from new variety ＋ FSS and farmers＇ variety ＋ CS were at par. Scientific knowledge generated in this research demonstrated that use of CS ＆new wheat varieties is best option, while growing new varieties with FSS is a second choice for the advantages accruing from their built-in genetic traits of economic importance over growing CS of old and obsolete varieties. Having more flexible seed system will help accelerate the delivery of new genetic gains to farmers＇ fields.

In this paper, the authors revisit decentralized control of linear quadratic(LQ) *** of imposing an assumption that the process and observation noises are Gaussian, the authors assume that the controllers are restricted to be linear. The authors show that the multiple decentralized control models, the form of the best linear controllers is identical to the optimal controllers obtained under the Gaussian noise assumption. The main contribution of the paper is the solution ***, optimal controllers for decentralized LQ systems are identified using dynamic programming, maximum principle, or spectral decomposition. The authors present an alternative approach which is based by combining elementary building blocks from linear systems, namely, completion of squares, state splitting, static reduction, orthogonal projection,(conditional) independence of state processes, and decentralized estimation.

This study evaluates the efficacy of sustainable erosion control using slag-based alkali-activated cement crusts under varying rainfall and wind conditions. The rainfall intensities ranged from 30 mm/h to 120 mm/h, with durations ranging from 15 min to 90 min, and crust slopes of ∼2° (gentle) and 30° (steep). Wind tunnel experiments were conducted at wind velocities of 14 m/s, 21 m/s, and 28 m/s to investigate post-rainfall wind erodibility, along with changes in crust strength and microstructure analysis. The findings show the development of hydrated cementitious phases in alkali-activated material, which form around and between the particles during the alkaline activation process. Alkali-activated cement crusts significantly reduced erosion caused by rainfall and subsequent wind by several orders of magnitude. At the highest rainfall intensity of 120 mm/h, rainfall erosion was measured to be 1654.81 kg/m2 for untreated samples and 0.89 kg/m2 for treated samples, demonstrating a substantial 99.95% reduction in erosion due to the treatment. Similarly, at the highest wind speed tested, wind erosion was 122.75 kg/m2 for untreated samples and 0.095 kg/m2 for treated samples, indicating a significant 99.92% reduction in erosion due to the formation of an alkali-activated cement crust on the soil surface. However, exposure of the samples to 120 mm/h rainfall for 90 min resulted in a 5.2-fold increase in wind erosion compared to pre-rainfall conditions. Similarly, penetrometer results indicated a 37%–54% reduction in post-rainfall surface strength.
