Female Higher education in selected Arab States: Challenges and Achievements
No full textThe true wealth of any nation is its people and their ability to manage the country's existing resources and to identify and develop new ones which determines the prosperity of the economy and the health of society for present and future generations. To educate a man the result is educated man but to educate a woman is to educate the whole society. This article seeks to explore the changes of the Arab female's higher education, challenges and achievements in last ten years as a part of strategies to improve female well-being and societies’ economic and ability to provide the requirements of social development. Females in Arab states today are intensively pursuing higher education and professional careers as faculty members. Since ten years there was a shortage of public and private universities for women, and this caused a large number of young single women to stay at home, particularly as work opportunities remain limited. Higher education of Arab female in the last ten years faces great challenges due to the revolution of knowledge, development of the e-learning, distance learning and the need of higher standard of alumni to meet the work competitions and needs. This paper concluded the reports of the gender parity index (GPI) of female Higher education to male and the achievements and challenges facing them in selected Arab states
Impact of Manual Therapy, Supervised Exercises and Electro
No full textOsteoarthritis of knee joint is the most form of arthritis. To compare the impact of clinical physical
Therapy program versus home-based physical therapy program among female with knee osteoarthritis. Forty females with knee osteoarthritis were randomly assigned to clinic and divided into two equal groups. Group (A) received manual therapy, supervised exercises and electro-acupuncture like TENS and home exercise program, and group (B) received the same exercises as group A. Participants were evaluated by measuring knee range of motion, pain and use Arabic version of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Group A, showed increase in knee flexion by 18.14%, and extension by 78.60%, reduction in pain by 51.90%. WOMAC demonstrated 53.07% pain reduction, 58.94% in stiffness and 49.30% increase
in physical function. For group B, knee flexion was increased by 4.20%, knee extension by 24.66% and pain decreased by 23.94%. WOMAC reported reduction 31.81% in pain, 30.09% in stiffness and 12% increased physical function. Both clinical and home exercise programs were effective in improving knee osteoarthritis. The home exercise program can be used to reduce cost, save time and reduce OA patient's waiting list in physical therapy clinic
الدور السياسي للألعاب الرياضية
No full textيناقش البحث الدور السياسي للألعاب الرياضية منطلقا من تصور محدد مؤداه أن الألعاب الرياضية تعد متغيرا وسيطا يلعب دورا مزدوجا ذي بعدين. البعد الأول هو أنها انعكاس للقيم والنظم الاجتماعية السائدة. ومن ثم فلا يمكن النظر للألعاب الرياضية كممارسات بدنية محايدة تهدف إلى تحقيق المتعة للمشاركين فيها والمتفرجين عليها، فهي نشاطات ومؤسسات تعكس قيم المجتمع واتجاهاته وعقائده. أما البعد الثاني فينظر إلى الألعاب الرياضية كأداة سياسية تستخدم لتحقيق وظائف متعددة في المجتمع. ومن ثم فالألعاب الرياضية تعد متغيرا مستقلا يحقق وظائف سياسية سواء بالنسبة للحكومات أو الحكام أو الجماهير. ويناقش البحث هذين الفرضين من خلال دراسة العلاقة بين الدولة والألعاب الرياضية وذلك بتحليل تأثير العقيدة التي تحملها الدولة على دور الألعاب الرياضية الاجتماعي ، ثم دراسة دور الألعاب الرياضية في خدمة أغراض الدولة مثل استخدام الألعاب الرياضية لاكتساب الشرعية للنظام السياسي، وخلق وتعميق الولاء الوطني، وتجذير السلوك السياسي المحافظ، وكأداة للتصريف السياسي. كما يناقش البحث العلاقة بين الألعاب الرياضية والقيادة السياسية من خلال دراسة استخدام القادة للألعاب الرياضية لأغراض سياسية شتى. ثم يتناول البحث بعد ذلك النتائج السلبية الاحتمالية للألعاب الرياضية من خلال دراسة العلاقة بين الألعاب الرياضية والعنف، وتكريس السياسة الاجتماعية. وتطرح الدراسة في الخاتمة تساؤلا حول إمكانية جعل الألعاب الرياضية وسيلة غير سياسية لبناء الأجساد وتنتهي إلى أنه طالما أن الألعاب الرياضية تستخدم لتحقيق أغراض سياسية للدولة فإن فصلها عن الظاهرة السياسية أمر يصعب الوصول إليه في المجتمع المعاصر.جامعــــة الملك سعو
Isolation and characterization of multiple-lectins from serum of the desert locust Schistocerca gregaria (Orthoptera: Acrididae)
No full textThree lectins, designated as Sg1, Sg2 and Sg3, were identified in the serum of the desert locust Schistocerca gregaria. With the use of (NH4)2SO4 fractionation, ion-exchange chromatography on DEAE-cellulose, and affinity chromatography on CNBr–activated Sepharose 4B, three pools, each containing one of the putative lectins, were obtained. IEF, native PAGE and SDS/PAGE revealed that the three pools contained Sg1, Sg2 and Sg3, respectively, with pI = 6.39, 8.11 and 6.8; native PAGE Rm = 0.44, 0.32 and 0.32; SDS/PAGE subunits approximate molecular weights = 21.5, 44.5, and 43.9 kDa, respectively. Under reducing conditions, SDS/PAGE has separated each of Sg2 and Sg3 into two bands that indicate the presence of covalent interactions between their subunits, which are not present in Sg1. The three lectins are more highly specific for rabbit RBCs than for those of other vertebrates. The HA of lectins are Ca2+−dependent, heat-labile, and are inhibited strongly by α-linked-D-galactosides, followed by L-(+)-rhamnose
Doxorubicin toxicity can be ameliorated during antioxidant L-carnitine supplementation
No full textDoxorubicin is an antibiotic broadly used in treatment of different types of solid tumors. The present study investigates whether L-carnitine, antioxidant agent, can reduce the hepatic damage induced by doxorubicin. Male Wistar albino rats were divided into six groups: group 1 was intraperitoneal injected with normal saline for 10 consecutive days; group 2, 3 and 4 were injected every other day with doxorubicin (3 mg/kg, i.p.), to obtain treatments with cumulative doses of 6, 12 and 18 mg/kg. The fifth group was injected with L-carnitine (200 mg/kg, i.p.) for 10 consecutive days and the sixth group was received doxorubicin (18 mg/kg) and L-carnitine (200 mg/kg). High cumulative dose of doxorubicin (18 mg/kg) significantly increases the biochemical levels of alanine transaminase, alkaline phosphatase, total bilirubin, thiobarbituric acid reactive substances (TBARs), total nitrate/nitrite (NOx) p < 0.05 and decrease in glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GSHPx), glutathione-s-transferase (GST), glutathione reductase (GR) and catalase (CAT) activity p < 0.05. The effect of doxorubicin on the activity of antioxidant genes was confirmed by real time PCR in which the expression levels of these genes in liver tissue were significantly decrease compared to control p < 0.05. Interestingly, L-carnitine supplementation completely reversed the biochemical and gene expression levels induced by doxorubicin to the control values. In conclusion, data from this study suggest that the reduction of antioxidant defense during doxorubicin administration resulted in hepatic injury could be prevented by L-carnitine supplementation by decreasing the oxidative stress and preserving both the activity and gene expression level of antioxidant enzymes
Experiments on Automatic Recognition of Nonnative Arabic Speech
No full textThe automatic recognition of foreign-accented Arabic speech is a challenging task since it involves a large number of nonnative accents. As well, the nonnative speech data available for training are generally insufficient. Moreover, as compared to other languages, the Arabic language has sparked a relatively small number of research efforts. In this paper, we are concerned with the problem of nonnative speech in a speaker independent, large-vocabulary speech recognition system for modern standard Arabic (MSA). We analyze some major differences at the phonetic level in order to determine which phonemes have a significant part in the recognition performance for both native and nonnative speakers. Special attention is given to specific Arabic phonemes. The performance of an HMM-based Arabic speech recognition system is analyzed with respect to speaker gender and its native origin. The West Point modern standard Arabic database from the language data consortium (LDC) and the hidden Markov Model Toolkit (HTK) are used throughout all experiments. Our study shows that the best performance in the overall phoneme recognition is obtained when nonnative speakers are involved in both training and testing phases. This is not the case when a language model and phonetic lattice networks are incorporated in the system. At the phonetic level, the results show that female nonnative speakers perform better than nonnative male speakers, and that emphatic phonemes yield a significant decrease in performance when they are uttered by both male and female nonnative speakers

Secure Identification System-SIS
No full textThe secure identification of a person was and still of great interest in different
fields of human activities. The traditional identification methods such as PIN,
passwords aren’t capable to achieve a high level of secure identification. In the
contrast, the biometrics allows to attain the suitable solution for this vital question.
Different types of biometrics are reviewed. Its characteristics are unique for each
person either for physiological or behavioral biometrics. It is shown that the
fingerprint recognition has a very good balance of all desirable properties.
The design of secure identification fingerprint-based system, in its hardware and
software parts, is done. This system was implemented with the suitable features
