    The Aswan granitic rocks occupy a region in southern Egypt between the stable Archaean craton of the south Western Desert and the less stable Pan-African belt of the south Eastern Desert. They include light-grey medium grained granites, red coarse-grained granites and fine-grained granites. The setup, field relations and petrography of the granitic rocks are discussed in detail. Seventeen new chemical analyses for both major and trace elements are presented. Also, the chemical analyses of four biotites, four feldspars and three magnetites separated from the granitic rocks are presented and three magnetites separated from the granitic rocks are presented and plotted on variation diagrams. The field evidences indicate that the Aswan granites should be classed with the post-collisional granites, whereas the petrochemical and geochemical data suggest progressive differentiation from the granodiorite through monzogranite to syenogranite and that they are probably related to a single magmatic intrusive sequence. The Aswan granites have a related petrogenetic history with the calc-alkaline volcanic suites of the south Eastern Desert.تحتل صخور أسوان الجرانيتية منطقة في جنوب مصر تقع بين راسخة الاركي الثابتة بجنوب الصحراء الغربية وحزام ألبان - افريقي Pan - African الأقل ثباتا بجنوب الصحراء الشرقية وتشتمل على تنوع من الجرنيتات متوسطة التحبب الرمادية - الناتجة ، الجرانيتات خشنة التحبب الحمراء اضافة إلى الجرانيتيات دقيقة التحبب . يناقش البحث بالتفصيل التوضع والعلاقات الحقلية لهذه الصخور الجرانيتية كما يقدم سبعة عشر تحليلا كيميائيا جديدا للعناصر العظيمة والشحيحة اضافة إلى تحاليل لأربع من كل من البيوتايت والفلسبار اضافة إلى ثلاث من المجنيتيت . وقد دلت الأدلة الحقلية على أن جرانيتات أسوان يجب أن تصنف ضمن الجرانيتات البعد تصادمية في حين دلت المعلومات الجيوكيميائية على عمليات تفارق متتالية من الجرانوديوريىت عبر المونزوجرانيت إلى السيانوجرانيت والتي تنتمي على أغلب الظن تتابع تداخلي مجماتي واحد ويبدو كذلك أن جرانيتات أسوان تنتمي في أصولها إلى البركانيات الكلس -قلية بجنوب الصحراء الشرقية المصرية

    We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
