The use of roller compacted concrete (R.C.C) without conventional cover in important hydraulic structures is investigated through laboratory observation of abrasion phenomena sujected to high velocity flow and floating particles. The main parameters affecting abrasion and erosion resistance of R.C.C. studied in the present study include: "Mixed Hydraulic

Mean Radius" (which collectively ...
BACKGROUND Escherichia coli (E. coli) is a frequent uropathogen in urinary tract infections (UTI). Widespread resistance to sulfamethoxazole-trimethoprim (SMX-TMP) and increasing resistance to fluoroquinolones amongst these isolates has been recognized. There are limited data demonstrating risk factors for resistance to both SMX-TMP and fluoroquinolones. OBJECTIVE This study was conducted to ...
Background: Staphylococcus aureus is a facultative anaerobic Gram-positive coccal bacterium which is frequently found as part of the normal flora on the skin and nasal passages. S. aureus can cause a range of illnesses from minor skin infections to life-threatening diseases. The organism is able to developresistance to a wide range of antibiotics. Resistance to antibiotic is one of th...
Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...
Background and purpose: Acinetobacter Baumannii is an opportunistic bacterium, which is considered as a concern in hospitals throughout the world due to high antibiotic resistance rate. The aim of this study was to investigate the prevalence of carbapenem resistance genes in clinical isolates of this bacterium. Materials and methods: In this study, 100 clinical isolates of Acinetobacter Bauman...
Evaluation of resistance to powdery mildew and identification of resistance genes in wheat cultivars
Wheat powdery mildew, caused by the biotrophic fungus Blumeria graminis f. sp. tritici ( Bgt ), is a serious disease of wheat worldwide that can cause significant yield losses. Growing resistant cultivars most cost-effective and eco-soundly strategy to manage disease. Therefore, high breeding priority identify genes be readily used either singly or in combination for effective resistance mildew...
background: the interim restorative materials should have certain mechanical properties to withstand in oral cavity. the aim of this study was to evaluate the hardness and wear resistance ofinterim restorative materials. materials and methods: fifteen identical rectangular shape specimens with dimensions of 2 mm × 10 mm × 30 mm were made from 7 interim materials (tempspan, protemp 3 garant, rev...

Background & Objective: Urinary tract infection is one of the most common bacterial infections in humans and its appropriate treatment is extremely important. Occurrence of antibiotic resistance in bacterial pathogen is a worldwide problem. The evaluation of bacterial susceptibility pattern and recognizing the prevalent resistances can be helpful for appropriate treatment and management....
