The main objective of this study is to predict soil erosion in the Lattakia Governorate(W Syria) using the Water Erosion Prediction Project model(WEPP) and to compare the result with that of the RUSLE. Field survey and data collection were carried out, and 44 soil samples were analyzed. In addition, all the necessary input files were prepared for use in the WEPP model and RUSLE. Results show that more than of 80% of the locations studied experience slight to moderate erosion(less than 5 t/ha/y), whereas the rest of the locations experience severe soil erosion hazard. Moreover, the volume of runoff estimated by the WEPP model is in the range of 51 e321 mm, and the R~2 between the simulated soil erosion and the predicted runoff reached 0.68. Interestingly, the R~2 between the WEPP model and RUSLE is 0.56, which indicates a good correlation between the two models.

本研究工作提出了一种强大、高效并且可靠的Homa传输协议修改方案。我们引入了一种新颖、直接并且高效的按报文大小确定优先级的算法。首先,根据传入流量,更改未进行优先级调度的截止报文的大小范围。我们使用显式机制确定截止范围,并根据负载报文大小确定优先级。其次,我们选择了最佳比例来分配优先级,并据此更改已调度和未调度数据包的优先级数。关于Homa传输协议的修改方案是直接的,并不复杂,并且可以被认为是根据报文大小确定优先级算法的一种良好的替代方案。此外,所提出的确定优先级算法的核心思想是根据先前负载报文大小的统计信息显示地分配优先级。除了方案中修改的地方,我们的工作基于与之前Homa工作完全相同的机制。因此,我们的研究工作令人非常满意,而且性能相对较高。此外,我们的研究工作引入了充分的调研,了解报文大小映射优先级对DCN中Homa传输协议性能的影响。仿真结果表明,我们提出的方法提高了 Homa在高网络负载情况下的性能,并且令人满意。在90%的网络负载下,它将短报文的传输延迟降低到了14μs左右,并最大限度地减少了接收端下行链路侧(TOR和接收端之间)的队列长度-与Homa传输协议相比减少了 40%。此外,在相同的网络负载(90%)下,我们提出的方法可提供高达85%的带宽利用率。

Energy and Exergy Analysis of a Finned-Plate Double Pass Solar Air Heater with Different Arrangement

引用

Journal of Power and Energy Engineering 2020年第10期8卷 1-17页

作者： mohammed S. fahmi Wissam H. Khalil Amer J. Shareef Mechanical Engineering Department Engineering College University of Anbar Ramadi Iraq Renewable Energy Research Center University of Anbar Ramadi Iraq

The present work investigated the solar collector system with triangular longitudinal fins fixed to the absorber surface at different configuration. Four models of collectors were manufactured with different absorber plates made from aluminum material. The experiments were carried out at the winter session in the climate of Iraq—Ramadi city with longitude (43.268) and latitude (33.43). The experiments have used three values from (0.027 to 0.037) kg/s. The results showed that the temperature difference increases gradually until midday and begins decreasing gradually until it becomes zero at sunset. Maximum temperatures difference has been obtained at the fourth type which is (20.6 °C), and maximum efficiency and exergetic efficiency (99.9%), (43.08%) respectively. A comparison has been made with previous works for thermal and exergetic efficiency. The comparison showed good compatibility between results; the percentage of error does not exceed 3%. The results proved that the existence of fins was a good technique for enhancing the thermal performance of double pass solar collector with a non-effective increase in pressure drop.

Pulmonary and Extra Pulmonary Tuberculosis in Qatar: A First Retrospective Population-Based Study

引用

Advances in Infectious Diseases 2015年第4期5卷 148-153页

作者： mohammed Abu Khattab fahmi Yousef Khan Mona Al Maslamani Abdul Latif Al-Khal Akram El Gendy Hussam Al Soub Faraj S. Howady Division of Infectious Disease Department of Medicine Hamad General Hospital Doha Qatar Department of Medicine Hamad General Hospital Doha Qatar

Background: There is limited information about extra pulmonary tuberculosis (EPTB) in Qatar. The aim of this study is to describe the demographic characteristics of patients with Tuberculosis (TB) in Qatar, and to compare the characteristics of EPTB with those of Pulmonary Tuberculosis (PTB). Patients and Methods: The study was conducted at Hamad Medical Corporation (HMC) in Qatar, from January 2005 to December 2008. It involves all cases of TB diagnosed in Qatar which do not include patients who are diagnosed by routine screening tests upon entry to state of Qatar. Results: 1221 cases of TB were reported;654 (53.6%) were EPTB;and 567 (46.4%) were PTB. Nine hundred fifty-one (77.9%) were males and two hundred and seventy (22.1%) were females;the mean age was 32.7 ± 811.7 years;only 6.9% (84/1221) of them were Qataris. The most frequent associated condition was diabetesmellitus (DM) (30;2.5%), and the most frequent site involved was lymph node (285 cases;43.5%). One thousand two hundred patients continued on first-line drugs while 21 patients received second line treatment. The mean duration of antituberculous therapy was 6.7 ± 1.7 months. Hepatitis was the main drug toxicity. Eight hundred and forty seven patients (69.3%) cured and eight patients (0.7%) died, whereas the remaining three hundred and sixty-six patients (30.0%) had left the country before completing therapy. The proportion of EPTB among females was higher than males, whereas diabetes mellitus was strongly associated with PTB. Conclusion: TB is still common in Qatar with predominance of EPTB. Although male predominated, the proportion of TB, EPTB among females was higher than males.
