The al Haruj Intra-continental Volcanic Province is the largest part of the extensive volcanic activity in Libya which is considered to be a typical within plate basalts. The volcano-tectonics evolution of this province, as well as its origin, are still widely disputed. According to K-Ar dating previously studied, the volcanic activity started in the Late Miocene and lasted until at least the Late Pleistocene. The field may still be volcanically active. The mafic rocks of Jabal al Haruj have been classified into six major phases or groups. These phases have been differentiated using Landsat images together with aerial photographs of different scales as well as field observations. The topographic forms of the earliest phase are highly eroded while the forms of the latest phase are usually fresh and very well preserved as regards primary features. Mafic lavas of this field consist of alkali basalts to olivine tholeiites (transitional basalt) which contain olivine as essential constituent together with clinopyroxene, plagioclase and glass. The basalt exhibits intergranular, intersertal, ophitic and subophitic relations. Amygdaloidal and glomerporphyritic textures are also observed. The basaltic rocks of different ages and from different localities are petrographically rather similar. Phenocrysts of olivine probably the result from slow cooling in crustal magma chambers prior to eruptions, suggesting that magmas ascended slowly through the crust. 109 samples have been carefully collected from various phases, some of these samples have been chosen for major and trace elements analyses, using XRF in order to determine the characteristics of the?mantle source and investigate crustal interaction. The major and trace elements revealed a?slightly significant chemical diversity among the phases and within each phase. The normative classification of most of these rocks shows close agreement with their modal classification. A vague correlation between MgO and most major oxides i

The Red Palm Weevil （RPW）, Rhynchophorus ferrugineus （Olivier）, （Coleoptera, Curculionidae, Rhynchophorinae）, is an invasive species that is originated from Southeast Asia. It *** Middle East and several countries of the Mediterranean Basin during the last three decades where it attacks palm trees. During the last three decades, multiple introductions of RPW to the Middle East, Europe and Caribbean （Island of Curacao, Netherland Antilles）, Lebanon and United States of America （Laguna Beach, Orange County, California）（USA） have occurred and the RPW is now a serious pest of many palm species. Duration of all life parameters varies significantly where the entire life cycle takes about 45 to 298 days. Different artificial diets were developed and were tested for mass rearing of RPW. Control of RPW is difficult due to the concealed nature of the life cycle of the pest. Integrated Pest Management （IPM） strategy has been applied successfully to deal with RPW problem. The IPM strategy consists of various preventive and curative methods; those methods were categorized in nine categories in this review. The main objective of this work was to review the existing knowledge on RPW＇s different aspects, with an ultimate aim of revealing the actual situation of the research on RPW.

Thin films of Nickel Phthalocyanine have been prepared by evaporation technique for (50 - 350 nm) of thickness. XRD studies show that the thin films have single crystalline structure for low thicknesses with (100) orientation and the crystallite size increased with increased thickness. also from the AFM technique for NiPc films, the roughness was determined and the grain size increases with increasing of thickness from except at thickness 350 nm. The studies of electrical properties, morphology and orientations of the crystallites are important to understand and predict the nature of the films and essential for their successful applications in solar cell and sensors. The electrical properties of these films were studied with different thickness, NiPc has three activation energy. Carrier’s concentration and mobility was calculated. Hall measurements showed that all the films are p-type.

Potentiality of Secondary Aquifers in Saudi Arabia: Evaluation of Groundwater Quality in Jubaila Limestone

引用

International Journal of Geosciences 2012年第1期3卷 71-80页

作者： Mohammed Tahir Hussein Mazin. M. al Yousif Hussein S. Awad SGSRC Department of Geology College of Science King Saud University Riyadh Saudi Arabia

Groundwater scarcity in arid regions may hinder development plans and cause many inconveniences for the population and authorities. Saudi Arabia has limited groundwater resources stored in the sedimentary sequence of the Arabian Shelf. Some of these resources were classified as major aquifers, secondary and minor aquifers, and some were considered as aquicludes. The Jubaila Limestone is one of the secondary aquifers of Saudi Arabia. The main purpose of this paper is to evaluate the groundwater resources of the Jubaila Limestone in Riyadh area, with emphasis on groundwater quality. Groundwater was found to occur in fractures and within solution openings of the Jubaila Limestone at depths which range between 19 and 210 m. The transmissivity value was 1.7 × 10–3 to 7.2 × 10–3 m2/s;the storage coefficient was of 1.3 × 10–4. The electrical conductivity for collected water samples ranged between 831 and 7670 μS/cm. The major ionic relationships were Na > Ca > Mg and SO4Cl > HCO3. The groundwater evolves from NaCl dominated at the southern end of the study area, into Ca, MgSO4 water in the north. The main chemical process responsible of this variation was found to be dissolution of anhydrite and gypsum. The groundwater was not found suitable for drinking purposes but can be used by livestock and for some agricultural purposes.

引用

E-Health Telecommunication Systems and Networks 2022年第3期11卷 109-130页

作者： Khaled Abdoh almuntaser ali Bakery Moussa Addeeb Abdulwahed al-Serouri Saud Mughalles Yasser Ghaleb Sana’a Health Office Ministry of Public Health and Population Sana’a Yemen Omdurman University-Sudan Omdurman Sudan Yemen Field Epidemiology Training Program Ministry of Public Health and Population Sana’a Yemen

Background: Total quality management (TQM) plays a major role in quality health services improvement. The aims of the study are to identify the concepts of total quality management in health institutions to know the nature of the relationship between the application of TQM and improving the quality of health services in Sana’a Governorate. Method: This applied research is a descriptive cross-sectional study in which the TQM of 13 affiliated Sana’a Governorate hospitals during “2017-2020”, were evaluated based on self-administered questionnaires. Data were collected by questionnaires including demographical variables, TQM dimensions variables. Data were analyzed by using SPSS version 16. Results: A total of 281 users 98.6% had responded. The employee’s responses for sixth study dimensions were the top manager’s commitment (TMC) 80.46%, customers focusing CF 81.55%, continuous improvement (CI) 82.32%, training (T) 71.51%, and strategic planning of the quality (SPQ) 74.76%, health services quality improvement (HSQI) 74.25%. There is a strong relationship between TQM and HSQI. There is no relationship between demographic factors gender, profession, years of experience, except age with TMC, T, HSQI, qualification with the TMC, CI, T, HSQI and job with all study variables. Conclusion: The application of TQM at hospitals in quality of health services improvement has several challenges, lacking staff experience and lacking leadership support, weakness of the training, customers focusing, continuous improvement, and strategic planning of the quality. Therefore, benefiting from the experiences of leading hospitals in implementing total quality management programs by sending some cadres to these hospitals for training and gaining experience or by hosting experienced cadres to conduct training courses is recommended.

Pharmacological evaluation of a novel enhydrazone ester (CEE-1) as a dual inhibitor of the release of pro-inflammatory cytokines and prostanoids from human monocytes

引用

Advances in Bioscience and Biotechnology 2013年第8期4卷 54-63页

作者： Charles I. Ezeamuzie Hanan Zamil Hawraa al-Baghli Ivan O. Edafiogho Department of Pharmaceutical Sciences School of Pharmacy University of Saint Joseph Hartford USA Department of Pharmacology & Toxicology Faculty of Medicine Kuwait University Kuwait City Kuwait

CEE-1 (ethyl 4-phenylhydrazinocyclohex-3-en-2-oxo-6-phenyl-1-oate)—a novel enhydrazone ester, was tested in vitro for anti-inflammatory activity against the release of pro-inflammatory cytokine and prostanoid from lipopolysaccharide-activated human monocytes or human monocytic cell line (U937). The effects were compared with those of standard anti-inflammatory drugs dexamethasone and indomethacin. CEE-1 potently and strongly inhibited the release of both tumor necrosis factor-alpha (TNF-α) and prostaglandin E2 (PGE2). The concentrations producing 50% inhibition (IC50 values) were 2.0 μM and 2.4 μM for TNF-α and PGE2, respectively. At 30 μM, the drug achieved almost complete inhibition of both mediators. Dexamethasone had similar effects but indomethacin inhibited only the PGE2 release, and although CEE-1 was less potent than these two drugs, it had comparable efficacy. The compound appeared to act, at least, in part by inhibiting the up-regulation of the mRNA for TNF-α as well as that of the prostanoid-synthetic enzyme, cyclo-oxygenase-2 (COX-2). However, like dexamethasone, but unlike indomethacin, CEE-1 did not affect COX-2 enzyme function. Thus, the profile of activity of CEE-1 is similar to that of steroids rather than the non-steroidal anti-inflammatory drugs. Structure-activity study showed that the presence of a simple aromatic ring attached via an NH-NH group was critical for activity. At the concentrations that completely inhibited mediator release, the compound displayed no significant in vitro toxicity on the cells. These results show that CEE-1 is a dual inhibitor of the release of cytokines and prostanoids, and therefore could be a potential alternative to steroids in the treatment of inflammatory diseases.
