    يعتبر شط الحلة في محافظة بابل احد المصادر الرئيسية للماء في مدينة الحلة ويستخدم لاغراض مختلفة. الهدف من البحث هو دراسة نوعية المياه السطحية ضمن منطقة الدراسة ومدى ملائمتها للاغراض المذكورة سابقا ,كذلك تصنيف نوعية المياه. تضمنت الدراسة تحليل 9 نماذج للمياه السطحية على طول شط الحلة, من العناصر الكيميائية التي تم تحليلها (Ca2+, Mg2+, Na+, K+)  و (HCO3=, CO3=, SO42-, Cl-) ومن العناصر الاخرى (NO3=) و(PO43-), وكذلك قياس العسرة الكلية و التوصيلية الكهربائية والاملاح الكلية الذائبة . اظهرت نتائج مؤشر نوعية المياه ان المياه تراوحت بين الجيد الى الممتاز, مخطط بابيبر اظهر نوع المياه من النوع c  والذي يدل المياه ذات اصل قلوي ارضي مع زيادة القلوية بزيادة الكبريتات والكلورديات. تم قياس ملائمة المياه للاغراض المختلفة وذلك بمقارنتها مع مقياس منظمة الصحة العالمية ومع المقياس العراقي وقد اظهرت نتائج المقارنة ان المياه ملائمة للاغراض والاستخدامات المختلفة ( لغرض الشرب, الري, للمواشي, لغرض البناء) عدا عن استخدامها للاغراض الصناعية وذلك لزيادة تراكيز العناصر الكيميائية عن الحد المسموح به.Shatt Al Hilla River within Babylon Governorate is one of the main water resources in Hilla citys which uses for different purposes. The object of this paper is studying the quality of surface water resources in the study area besides determining its suitability for different anthropogenic uses and classifying the water type. This study included the analysis of (9) surface water samples along the river, those analyses included chemical parameters such as (Ca2+, Mg2+, Na+, K+) and main anions (HCO3=, CO3=, SO42-, Cl-) and other important anions, i.e. Nitrate (NO3=) and (PO43-), Total Hardness, Electrical Conductivity, Total Dissolved Salts. Results of Water quality index ranged from good to excellent type, Piper Diagram referred to water of class (c) which means the water of Earth Alkaline source with increasing in portions of Alakalis under prevailing sulfate and Chloride. Water suitability conducted by comparing with World health organization standers and Iraqi standers, the result of water suitable for different uses (drinking, irrigation, livestock, building purposes) except for industrial uses because of the high concentrations of the chemical parameters

    Influence of limestone filler and of the size of the aggregates on DEF

    This experimental study aims to determine the effect of limestone filler on concrete expansion due to delayed ettringite formation (DEF). Different mortars made with different sizes and percentages of limestone filler and Portland cement CEM I 52.5N are conserved in water. The expansion of the specimens is measured. Results show that DEF is not inhibited by limestone filler. The kinetics and the amplitude of the swelling depend on the size of the limestone filler. The volume fraction of aggregates changes only the kinetics: the relation between swelling and water uptake depends only on the size of the aggregates.Comment: 16 pages, 9 figures, 4 table

    Marrow versus peripheral blood for geno-identical allogeneic stem cell transplantation in acute myelocytic leukemia: Influence of dose and stem cell source shows better outcome with rich marrow

    Several studies have compared bone marrow (BM) and peripheral blood (PB) as stem cell sources in patients receiving allografts, but the cell doses infused have not been considered, especially for BM. Using the ALWP/EBMT registry, we retrospectively studied 881 adult patients with acute myelocytic leukemia (AML), who received a non-T-depleted allogeneic BM (n = 515) or mobilized PB (n = 366) standard transplant, in first remission (CR1), from an HLA-identical sibling, over a 5-year period from January 1994. The BM cell dose ranged from 0.17 to 29 × 108/kg with a median of 2.7 × 108/kg. The PB cell dose ranged from 0.02 to 77 × 10 8/kg with a median of 9.3 × 108/kg. The median dose for patients receiving BM (2.7 × 108/kg) gave the greatest discrimination. In multivariate analyses, high-dose BM compared to PB was associated with lower transplant-related mortality (RR = 0.61; 95% CI, 0.39-0.98; P = .04), better leukemia-free survival (RR = 0.65; 95% CI, 0.46-0.91; P = .013), and better overall survival (RR = 0.64; 95% CI, 0.44-0. 92; P = .016). The present study in patients with AML receiving allografts in first remission indicates a better outcome with BM as compared to PB, when the dose of BM infused is rich. © 2003 by The American Society of Hematology
