A streptococci has recognized as Streptococcus spp., associate with acute pharyngitis. S. pyogenes infection Has detected in the Hospital and Health Center in Tikrit city. Throat swabs sample has obtained and cultured on a sheep blood agar plate. Identification of S. pyogenes was performed by using the VITEK 2 automatic system. It detected of 50 samples from children included 25 were positive for S. pyogenes infection. were aged 10-35 years old and included 30 male and 20 female. . While 25 sample Negative of S. pyogenes infection (The control group included 25 clinically healthy children without S. pyogenes infection matched for age and sex with cases pateints). No significant differences was reported between tonsillitis patients and healthy control in terms of Complement 4 proteins (33.21 ±14.18726 , 35.57±15.56254) , C3 (268.5±14.34 , 146.06±17.83) although increased complement level in patient group. The present study revealed no significant decrease levels of C4 of tonsillitis patients with negative ASOT than those with positive. the disease duration and ASOT have significant effect on CRP and complements components serum levels in patients with tonsillitis.
In this article four samples of HgBa2Ca2Cu2.4Ag0.6O8+δ were prepared and irradiated with different doses of gamma radiation 6, 8 and 10 Mrad. The effects of gamma irradiation on structure of HgBa2Ca2Cu2.4Ag0.6O8+δ samples were characterized using X-ray diffraction. It was concluded that there effect on structure by gamma irradiation. Scherrer, crystallization, and Williamson equations were applied based on the X-ray diffraction diagram and for all gamma doses, to calculate crystal size, strain, and degree of crystallinity. I

يُعد التنمر ظاهرة إجتماعية قديمة موجودة في جميع المجتمعات سواء أكان المجتمع صناعيًا أم ناميًا، كما يُعد من المفاهيم الحديثة نسبيًا، وربما يرجع لحداثة الإعتراف به نوعًا من أنواع العنف فضلاعن ندرة الدراسات التي تناولته وعدم وجود معيار محدد لتحديد السلوك الذي يعد تنمرًا أم عابرًا، لقد بدأ الأهتمام بدراسة التنمر في سبعينات القرن الماضي وأصبح موضعًا يحضى بأهتمام العديد في مختلف البلدان، وفي عصرنا الحالي تطورت

Show MoreIn this paper, we introduce and study a new concept named couniform modules, which is a dual notion of uniform modules, where an R-module M is said to be couniform if every proper submodule N of M is either zero or there exists a proper submodule N1 of N such that is small submodule of Also many relationships are given between this class of modules and other related classes of modules. Finally, we consider the hereditary property between R-module M and R-module R in case M is couniform.

In this paper, estimation of system reliability of the multi-components in stress-strength model R(s,k) is considered, when the stress and strength are independent random variables and follows the Exponentiated Weibull Distribution (EWD) with known first shape parameter θ and, the second shape parameter α is unknown using different estimation methods. Comparisons among the proposed estimators through Monte Carlo simulation technique were made depend on mean squared error (MSE) criteria

Abstract
This current research aims to make theoretical frame for the thoughts and principle knowledge for high performance work system ،also trying to know the role that high performance work system practices which is (Effective staffing، comprehensive training، providing work career، and employee participation) play to enhance the organization effectiveness ، although knowing the principles of high performance work system which is: (Shared Information، Knowledge Development Performance and Reward linkage Egalitarianism)and its effect on the organizations. As well as defining the special concept of High performance wo
