In this research paper, an attempt has been made to come across the effect of distance between double glazing on the efficiency of a solar thermal collector. Experiments were carded out on an active solar energy demonstration system （ET 200）. Commercial glass pane of 3 mm thick having the same dimensions as that of the apparatus was placed above the collector at a distance of 2 cm, 4 cm and 6 cm. Tests were done with and without the added glass. Experiments were performed for double glazing with two positions of the light meter. In one position, it was placed in the middle of the collector surface. While, in the other one, the light meter was placed in the middle of the added glass. To study the effect of double glazing on the performance of the solar collector ET 200, the correct position of the light meter was to place it exactly in the middle of the additional pane under the lamp. Double glazing does not enhance the performance of the solar collector because of the high resistance of the system glass air glass. The efficiency of double glazing solar collector decreases with the increasing the distance of the two separated glasses.

Different fungi alter apples in the post-harvest period, causing considerableeconomic losses and risks to consumer health due to the mycotoxinsthat some of these fungi produce. The control of these fungal alterationsin apples is mainly dependent on the use of chemical fungicides, the effectivenessof which has been well proven. However, this use is subject torestrictions due to growing concerns about risks to human health and theenvironment and the continued development of pathogen resistance to commonlyused fungicides. A new approach to control post-harvest fungi hasbeen implemented through the application of plant *** is estimatedthat there are more than 250,000 higher plant species on Earth that can beevaluated for their antimicrobial bioactive chemical compounds. In recentdecades, researchers have evaluated plant extracts and essential oils againstfungi responsible for post-harvest apple rot. Interesting results have beenobtained. The purpose of this project is to summarize and discuss the resultsof in vitro and in situ experiments of different literatures concerning the effectsof compounds derived from plants on the control of fungi responsiblefor rotting apples in storage.

背景:Brugada综合征（Brugada syndrome,BrS）是一种具有遗传倾向容易导致恶性室性心律失常事件的疾病,以心电图异常为特征,可导致心源性猝死。BrS有三种心电图表现。Brugada综合征估计占所有心源性粹死者4%～12%,占无器质性心源性猝死至少20%。全世界Brugada综合征的汇总患病率为0.5/1000。Brugada综合征因其在东南亚地区的高发生率以及在青壮年中容易发生心脏性猝死的高危险性而备受人们关注。福建省临近东南亚沿海,位于Brugada综合征高发地区,为Brugada综合征的研究提供了得天独厚的有利条件,研究Brugada综合征将为福建省、全国乃至整个东南亚地区Brugada综合征的防治提供重要资料。目的:本项目回顾性地研究厦门市BrS样心电图的发生情况,并随访心律失常事件的发生。（心律失常时间包括心源性猝死、室速或室颤、晕厥）方法和结果:2009年至2019年厦门大学附属第一医院心功能科门诊或住院期间有记录心电图的患者133万。共有238名患者入组（217名男性,21名女性）,Brugada样心电图的发生率是1.8/10,000。102（42.9%）人表现为Ⅰ型Brugada样心电图,130（54.6%）人表现为Ⅱ型,6（2.5%）人表现为Ⅲ型。男性患者中Ⅰ型BrS心电图有88人,Ⅱ型123人,Ⅲ型6人。女性患者中Ⅰ型BrS心电图14人,Ⅱ型BrS心电图7人,Ⅲ型为0。Ⅰ型、Ⅱ型和Ⅲ型BrS样心电图患者的平均年龄分别为53.3±15.2岁,52.6±15.5岁和59.3±14.3岁。在患有Brugada样心电图的受试者中,有5例晕厥的报道。结论:厦门市成年人的Brugada样心电图患病率较高,与先前的报告相比,本研究发现Ⅱ型Brugada样心电图的患病率高于Ⅰ型Brugada样心电图,而Ⅲ型Brugada样心电图的患病率最低。虽然患病率很高,但并不增加死亡率。

During the last decades, we have witnessed a widespread deployment of the ultra wide band (UWB) radar systems. Considering a medical field, an algorithm optimizing these systems is pointed out in this contribution. Beginning with the description of the UWB radar system, this algorithm has proved to be not only able to take a medical image of the human body but also capable of diverting the human tissue. Moreover, we insist on the fact that this algorithm can easily optimize different radar parameters. So, the human body layer width, the incident angle and the frequency maximizing reflection coefficient are estimated in this paper.

Recently, Islamic banks have been presented as an alternative to conventional banks. Indeed, Islamic banks have proved their worth during the 2009 crisis. They are known like an ethical bank. In Tunisia, only three Islamic banks exist. Even the conventional banks are interested to offer Islamic banking products and services; they are called Islamic banking window. This paper aims to determine the level of acceptance of Islamic banking window on Tunisian consumers and the impact of the social professional category on it. The research questions as follows： Are the consumers familiar with the financial Islamic products？ Did they perceive any differences between conventional and Islamic financial products？ What are the levels of acceptance of an Islamic banking product offered by a conventional bank？ In this respect, a questionnaire was administrated to a sample size of 120 people constituted of 54% men and 46% women from Tunis City. Three types of social professional category are found： 62% employee, 32% senior, and 6% profession. The data were processed by SPSS 21. The results showed that the majority of the respondents have a lack of knowledge of the Islamic banking products. The majority of the respondents don＇t see any differences between the product name of conventional and Islamic banking products. The acceptance level of an Islamic banking product offered by a conventional bank is very satisfying, 53% of the respondents are certain to purchase an Islamic banking product from a conventional bank and 42% are not sure. Only 5% refused.

Objective The beneficial effects of silymarin have been extensively studied in the context of inflammation and cancer treatment, yet much less is known about its therapeutic effect on diabetes. The present study was aimed to investigate the cytoprotective activity of silymarin against diabetes-induced cardiomyocyte apoptosis. Methods Rats were randomly divided into： control group, untreated diabetes group and diabetes group treated with silymarin （120 mg/ks·d） for 10 d. Rats were sacrificed, and the cardiac muscle specimens and blood samples were collected. The immunoreactivity of caspase-3 and Bcl-2 in the cardiomyocytes was measured. Total proteins, glucose, insulin, creatinine, AST, ALT, cholesterol, and triglycerides levels were estimated. Results Unlike the treated diabetes group, cardiomyocyte apoptosis increased in the untreated rats, as evidenced by enhanced caspase-3 and declined Bcl-2 activities. The levels of glucose, creatinine, AST, ALT, cholesterol, and triglycerides declined in the treated rats. The declined levels of insulin were enhanced again after treatment of diabetic rats with silymarin, reflecting a restoration of the pancreatic β-cells activity. Conclusion The findings of this study are of great importance, which confirmed for the first time that treatment of diabetic subjects with silymarin may protect cardiomyocytes against apoptosis and promote survival-restoration of the pancreatic β-cells.
