In this paper, ceramic water filters were produced by using ten mixtures of different ratios of red clay and sawdust under different production conditions. The physical properties of these filters were tested. The production conditions include five press pressures ranged from 10 to 50MPa and a firing schedule having three different final temperatures of 1000, 1070, and 1100˚C. The tests results of the physical properties were used to obtain best compatibility between the hydraulic and the mechanical properties of these filters. Results showed that as the press pressure and the firing temperature are increased, the bulk density and the compressive and bending strengths of the produced filters are increased, while, the porosity and absorp

Spot panchromatic satellite image had been employed to study and know the difference Between ground and satellite data( DN ,its values varies from 0-255) where it is necessary to convert these DN values to absolute radiance values through special equations ,later it converted to spectral reflectance values .In this study a monitoring of the environmental effect resulted from throwing the sewage drainages pollutants (industrial and home) into the Tigris river water in Mosul, was achieved, which have an effect mostly on physical characters specially color and turbidity which lead to the variation in Spectral Reflectance of the river water ,and it could be detected by using many remote sensing techniques. The contaminated areas within th

AshShinnafiyah and AsSamawa cities suffer from significant increase in salinity of Euphrates River water compared with their counterpart's north AshShinnafiyah city which is reflected adversely on the quality of water within the study area. The study aims to find possible solutions to avoid the deterioration of Euphrates River northern AshShinnafiyah city until AsSamawa city that were
presented by total dissolved solid TDS. Twelve main hydrological and fifteen salinity measurement stations were selected to cover 117 km of the river reach within the study area during July-2011. Additional twenty three hydrological and salinity stations were adopted during March-2012, winter season to the river within the study area. After conducting t

Ninety eight mobile samples, (54) galaxy phone and (44) I phone, were swabbed for bacterial culture determination by culturing on MacConky agar , Blood agar , Mannitol salt agar , Muller Hinton agar .Staphylococcuswas the highest frequent isolated bacteria from Galaxy phone (33%) and I phone (37%). This study revealed that galaxy phone appears less contaminated with bacteria, the ratio of non-contaminated devices is (44%) when compared with I phone (9%). Sensitivity test showed that Ogmintin have the lowest effect on Staphylococcusisolated from both type of devices while cefitriaxone have the highest effect. DNA of isolate from galaxy 31 that exhibit highest resistance against antibiotics was extracted and 16S rRNA gene was polymerized by P

ان استعمال الاساليب والنظريات العلمية الحديثة في عمل العلاقات العامة من شأنه ان يجعل عمل ادارات العلاقات العامة نافعاً ومؤثراً نافعاً للمؤسسة ومؤثراً في جمهورها ومحيطها الخارجي وكلما اتسع نشاط المؤسسة وكبر حجمها وامتدت الرقعة الجغرافية التي تنتشر عليها تشكيلات المؤسسة وفروعها كلما كبرت وكثرت التحديات والتهديدات التي تواجه المؤسسة ونشاطها وبذلك تكون الحاجة ماسة الى وجود ادارات متخصصة بالعلاقات العامة تس

مما لاشك فيه إن من أهم الأساليب التي تعتمد عليها أقسام العلاقات العامة في تحقيق أهدافها هو توظيف الخبر الصحفي ويشمل ذلك اهم أهداف العلاقات العامة ومنها التواصل مع الجماهير داخليه وخارجية ، بناء الصورة الذهنية الايجابية ، الإعلان ، الترويج ،..... الخ وفي اطار التطور الكبير الذي شهده علم العلاقات العامه في العقود الزمنية الاخيرة تزايد وتوسع الاعتماد على التوظيف الإخباري عن طريق بناء وتشكيل ومعالجة مضامين الخب

Background: The discriminative power of the classical WHO parameters in relation to male fertility is quite low, because they only address few aspects of sperm quality and function. This has led investigators to focus their attention on the male gamete and in particular its genome.Objective: To explore which of the sperm DNA damage parameters measured by comet assay are more reliable, and their relations with the standard semen parameters.Methods: Study was done on 40 infertile men selected from couples attending the Institute of Embryo Reasearch and Infertility Treatment at Al-Kadhimiya City/ Baghdad in the period between February 2009 and May 2009, with a history of infertility of ≥1 years; and 15 healthy volunteers of proven fertili
