Planned and achieved outputs in Saudi health care system: reducing the gap
No full textThis paper examines and compares the planned and actual output of the Saudi Arabian health care system during its Fifth Development Plan period (1990-1995). It then analyzes the inputs and the environmental factors available to the system and how these factors may have influenced the performance (process) of the system, and hence the planned output. The investigation reveals that some of the. planned outputs were achieved satisfactorily, while others fell short significantly. The possible reasons for the shortcomings have been discussed and recommendations have been put forward to reduce the gap between the planned and the actual outputs of the system.Corresponding Author:

The use of precedents in contemporary Arab architecture : case studies; Rasem Badran and Henning Larsen
No full textThesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1989.Includes bibliographical references (leaves 115-119).Much recent architecture in the Arab World utilizes historical precedents in an attempt to articulate an identity for regional architecture. This thesis investigates this approach in relation to place and cultural context. The study is focused on three institutional buildings from the Arab World: two projects by the architect Rasem Badran, Qasr alHoukm (Justice Palace) in Riyadh and the Presidential Palace in Bagdad, and Henning Larsen's Ministry of Foreign Affairs in Riyadh. The analysis examines the architects' designs and design research in order to reveal the architects' theoretical positions and their artifactual realizations. This approach allows for a deeper understanding design as a method and a production, and suggests an approach for architectural criticism.by Mohammed K. Ali.M.S

Energy yield framework to simulate thin film CIGS solar cells and analyze limitations of the technology
No full textAbstract This study presents a comprehensive evaluation of Copper Indium Gallium Selenide (CIGS) solar technology, benchmarked against crystalline silicon (c-Si) PERC PV technology. Utilizing a newly developed energy yield model, we analyzed the performance of CIGS in various environmental scenarios, emphasizing its behavior in low-light conditions and under different temperature regimes. The model demonstrated high accuracy with improved error metrics of normalized mean bias error (nMBE) ~ 1% and normalized root mean square error (nRMSE) of ~ 8%–20% in simulating rack mounted setup and integrated PV systems. Key findings reveal that the CIGS technology, while slightly underperforming in integrated, low-irradiance setups, shows comparable or superior performance to c-Si PERC technology in high-irradiance and high-temperature conditions. A significant focus of the study was on the low-light performance of CIGS, where it exhibited notable voltage losses. Our research highlights the importance of reducing the diode ideality factor for enhancing CIGS power conversion efficiency, particularly In low-light conditions. These insights provide a pathway for future research and technological improvements, emphasizing defect engineering, passivation strategies to advance the understanding and application of the CIGS technology
Féminismes islamiques /

Marjoram Relaxes Rat Thoracic Aorta Via a PI3-K/eNOS/cGMP Pathway.
No full textDespite pharmacotherapeutic advances, cardiovascular disease (CVD) remains the primary cause of global mortality. Alternative approaches, such as herbal medicine, continue to be sought to reduce this burden. is recognized for many medicinal values, yet its vasculoprotective effects remain poorly investigated. Here, we subjected rat thoracic aortae to increasing doses of an ethanolic extract of (OME). OME induced relaxation in a dose-dependent manner in endothelium-intact rings. This relaxation was significantly blunted in denuded rings. N(ω)-nitro-l-arginine methyl ester (L-NAME) or 1H-[1,2,4]oxadiazolo[4,3,-a]quinoxalin-1-one (ODQ) significantly reduced the OME-induced vasorelaxation. Cyclic guanosine monophosphate (cGMP) levels were also increased by OME. Moreover, wortmannin or LY294002 significantly reduced OME-induced vasorelaxation. Blockers of ATP-sensitive or Ca2+-activated potassium channels such as glibenclamide or tetraethylamonium (TEA), respectively, did not significantly affect OME-induced relaxation. Similarly, verapamil, a Ca channel blocker, indomethacin, a non-selective cyclooxygenase inhibitor, and pyrilamine, a H1 histamine receptor blocker, did not significantly modulate the observed relaxation. Taken together, our results show that OME induces vasorelaxation via an endothelium-dependent mechanism involving the phosphoinositide 3-kinase (PI3-K)/ endothelial nitric oxide (NO) synthase (eNOS)/cGMP pathway. Our findings further support the medicinal value of marjoram and provide a basis for its beneficial intake. Although consuming marjoram may have an antihypertensive effect, further studies are needed to better determine its effects in different vascular beds

No full textThesis. M.E. American University of Beirut. Baha and Walid Bassatne Department of Chemical Engineering and Advanced Energy, 2019. ET:7096.Advisor : Dr. Ali Tehrani, Professor, Chemical Engineering and Advanced Energy ; Co-Advisor : Dr. Kamel Aboughali, Professor, Mechanical Engineering ; Members of Committee : Dr. Mohammad N. Ahmad, Professor, Chairman, Chemical Engineering and Advanced Energy ; Dr. Nesreen Ghaddar, Professor, Mechanical Engineerig.Includes bibliographical references (leaves 73-79)Oil pollution is a critical problem that is caused by the activity of several industries and oil spills. It causes damage to the environment and human life. Thus, an effective and versatile technique is needed to treat the oily wastewater. The objectives of this thesis were to make (a) a hydrophobic porous membrane for separation of oil from water, and (b) a hydrophilic porous membrane by surface modification to remove water from oily wastewater by gravity. A series of polyvinyl chloride (PVC) electrospun membranes with various pore sizes (2.5 – 0.8 µm) was fabricated. The electrospinning process parameters such as voltage, tip-to-collector distance, and polymer-solvent ratio were optimized by Response Surface methodology to obtain a desired fiber diameter. The optimum conditions were found to be [polymer] = 16 wtpercent, the solvent ratio DMF:THF = 62.5:37.5, polymer feed rate = 1 ml-h, voltage = 11 kV, tip to collector distance = 14 cm, and drum speed = 500 rpm. The porosity, pore size distribution, hydrostatic pressure head, and membrane thickness were controlled by adjusting the electrospinning time. The pore size decreased with the increase of electrospinning time while the membrane thickness and hydrostatic pressure head increased. The resulting electrospun PVC membranes were superhydrophobic-superoleophilic with water contact angle above 140°. The chemical stability of the membrane against different conditions of pH and salinity was studied. Moreover, the oil filtration efficiency of the hydrophobic porous PVC membrane was investigated as a function of pore size for two membranes with the average fiber diameter of around 118 and 470 nm. The diesel oil recovery values after 45 minutes for the membranes with the average pore size of 2.5 µm and 0.8 µm were 95percent and 80percent, respectively. Hydrophilization of the PVC porous membranes was achieved by surface modification using two different approaches: (1) The membrane was first aminated with triethylenetetraamine (TETA) and then cationi
Impact of genital hygiene and sexual activity on urinary tract infection during pregnancy
No full textIntroduction: Urinary tract infection (UTI) is a bacterial infection commonly occurring during pregnancy. The incidence of UTI in pregnant women depends on parity, race, and socioeconomic status and can be as high as 8%.
Objective: The objective was to determine the association of UTI with genital hygiene practices and sexual activity in pregnant women.
Patients and Methods: From January 2011 to June 2014, a total of 200 pregnant women attending prenatal clinics in Al-Zahra Hospital and King Khalid Hospital in Saudia Arabia Kingdom were selected. Eighty pregnant women, who had positive urine cultures (cases), were compared with the remaining 120 healthy pregnant women matched for age, social, economic and education status, and parity (controls).
Results: In the present work, Escherichia coli were the infecting organism in 83% of cases. Factors associated with UTI included sexual intercourse ≥ 3 times/week (odds ratio [OR] =5.62), recent UTI (OR = 3.27), not washing genitals precoitus (OR = 2.16), not washing genitals postcoitus (OR = 2.89), not voiding urine postcoitus (OR = 8.62) and washing genitals from back to front (OR = 2.96) [OR = odds ratio].
Conclusion: Urinary tract infection in pregnant women was primarily caused by bacteria from the stool (E. coli) and that hygiene habits, and sexual behavior may play a role in UTI in pregnant women
