تعد المبارزة أحد الألعاب الرياضية التي يتأثر فيها الأداء بتطور القدرات الخاصة بالأداء ومنها تحمل (سرعة وقوة الأداء ),وأن أكثر الأساليب السابقة في تدريب تطوير تحمل(سرعة وقوة الأداء) بالمبارزة تكون على ارض صلبة مثل الخشب والألمنيوم آو الإسفلت وفي بعض القاعات يكون التارتان, وظل هذا الأسلوب لفترات طويلة في العراق ،حيث تستخدم تدريبات الإثقال التي تعمل على تنمية تحمل القوة . أما في الوقت الحاضر فقد ظهر اتجاه حديث في التدريب ,إذ نرى لاعبي كرة القدم لريال مدريد يؤدون تدريباتهم على الرمال الشاطئية بعد ثمان دقائق من تدريبات الإحماء والركض, ومن خواص التدريب على الرمل جعل مقاومة وزن الجسم أثقل لانغماس الرجل في الرمل مما يعطي مقاومة اكبر للجسم . و تكمن أهمية البحث من خلال الاطلاع على كثير من الدراسات والبحوث قد ثبت أن تطور القدرات الخاصة على اليابسة تؤدي إلى نتائج جيدة ،وكذلك نفس المجال بالنسبة لتدريباتها على الرمل . لذا هدفت الدراسة إلى التعرف على أي الأسلوبين أكثر فاعلية في تطوير تحمل( سرعة وقوة الأداء) بالمبارزة. واستخدم المنهج التجريبي على لاعبي منتخب شباب البصرة بالمبارزة والبالغ عددهم ( 12) لاعباً , وقسمت عينة البحث بالطريقة العشوائية إلى مجموعتين, حيث كانت المجموعة الأولى التجريبية(6 لاعبين) يتدربون باستخدام أسلوب التدريب بالمقاومات على الرمل , بينما كانت المجموعة الثانية الضابطة (6لاعبين) يتدربون باستخدام أسلوب التدريب بالمقاومات على الأرض (داخل القاعة الرياضية وكانت أرضيتها من الإسفلت (صب). وبعد الانتهاء من تطبيق المنهاج التدريبي باستخدام تدريبات المقاومة بوزن الجسم والإثقال الخفيفة على الأرض في القاعة الرياضية والتدريبات على الرمل تم تحويل البيانات إلى جداول. و لغرض اختبار الفرضية المتعلقة بدلالة الفروق بين الاختبارات القبلية والبعدية تم استخدام اختبار ( ت ) للعينات المترابطة. فاستنتجت الباحثة :وجود فروق معنوية بين المجموعة التي تدربت على أرضية القاعة ( الإسفلت) وبين المجموعة التي تدربت على الرمل ولصالح المجموعة التي تدربت على الرمل . وتوصي باستخدام التدريبات على الرمل لما لها من اثر ايجابي في تطوير تحمل (سرعة وقوة الأداء بالمبارزة ).
Pseudomonas aeruginosa is an opportunistic pathogen responsible for serious infections. At least three different exopolysaccharides, alginate, polysaccharide synthesis locus (Psl), and pellicle exopolysaccharide (Pel) make up the biofilm matrix in P. aeruginosa . The effect of temperature on the biofilm formation and gene expression was examined by microtiter plate and real-time quantitative polymerase chain reaction (qRT-PCR). To be able to determine the effect of temperature on biofilm formation and gene expression of P. aeruginosa, 303 clinical and environmental samples were collected. Pseudomonas aeruginosa was isolated from 61 (20.1%) and 48 (15.8%) of the clinical and e

It had been used two methods for the purposes of estimating and fitting which is the way the Principle of Maximizing Entropy: POME, and method of booting to nonparametric smoothing function for Kernel, to overcome the mathematical problems plaguing integrals contained in this distribution in particular of the integration of the incomplete gamma function, along with the use of traditional way in which is the Maximum Likelihood: ML.

In fact, the lack of clarity of the role of local government in planning and managing services has hindered development plans, and declined the level of services in rural areas, and has negative

Company for Drugs Industry in Samarra.
Methodology: A descriptive evaluation design is employed through the present study from 25th May 2011
to 30th November 2011 in order to evaluate the national standards for exposure chemical materials and dusts
in The State Company for Drugs Industry in Samarra. A purposive (non-probability) sample is selected for the
study which includes (110) workers from the State Company for Drugs Industry in Samarra. Data were

Asthma is a chronic inflammatory disease of airways mediated by T-helper 2 (Th2) cells involving complex signaling pathways. Although resveratrol has previously been shown to attenuate allergic asthma, the role of miRNA in this process has not been studied. We investigated the effect of resveratrol on ovalbumin-induced experimental allergic asthma in mice. To that end, BALB/c mice were immunized with ovalbumin (OVA) intraperitoneally followed by oral gavage of vehicle (OVA-veh) or resveratrol (100 mg/kg body) (OVA-res). On day 7, the experimental groups received intranasal challenge of OVA followed by 7 days of additional oral gavage of vehicle or resveratrol. At day 15, all mice were euthanized and bronchioalveolar fluid (BALF), se

Through social service tasks for the elderly, it natural for elder people to have some attitudes about the quality and nature of provided services, whether negative or positive. Accordingly, the current research is an attempt to investigate the attitudes of the elderly toward the social service provided to them in the nursery homes. The research sample included 60 elderly people chosen from the nursey home at Al-Karrada district and then a scale of attitudes was administered to them that had proved its reliability and validity. The study concluded with a set of recommendations and suggestions were.
This study illustrates in vitro effect of cold atmospheric plasma (CAP) on the treatment of Leishmania. In addition, the study evaluated the effect of drug treatment (pentostam) and the combination treatment of pentostan and CAP at different doses and incubation time 24 h in order to assess the most effective treatment. The duration of the cold plasma doses was 1 min, 2 min and 3 min, while the pentostam doses were 2.5 µg/ml and 5 µg/ml. The combinations therapies included combining the three cold plasma doses with the pentostam doses to test 6 combinations of treated in vitro. The maximum growth inhibition was given by combination treated 46% and 44% for donovani and tropica leishamnia respectively; these results give an indi
