To assess the yield and agronomic traits of snapbean cultivars in different planting times and methods, an experiment was conducted for two years in Zarghan using a split- split plot with three replications. The main plots were two snapbean cultivars, Sunray and Contender, subplots were three planting times, end of April, early in May and mid May, when temperature was 24.7, 26.9 and 25.2ºC, respectively and sub-sub plots were three planting methods and seeding distance on row, 10cm single row, 15 and 20 cm double cross-rows. Different agronomic traits and yield in different treatments were recorded in different growth stages. Analysis of variance on data showed that the effects of planting methods and seeding distance on row were not significant on yield, but the effects of cultivar and planting time were significant. Seed germination and seedling emergence in Sunray cultivar occurred earlier than in Cantender cultivar. Sunray cultivar with 43.02 tha-1 in the first year and 57.57 tha-1 in the second year, produced higher yield compared to Contender cultivar with 24.34 tha-1 yield in the first year and 39.08 tha-1 in the second year. Two years mean yield of Sunray (50.29 tha-1) was also higher than that of Cantender (31.71 tha-1). The first planting time (end of April) increased yield of both cultivars and there were significant differences among planting dates for yield and agronomic traits. Generally, Sunray cultivar with higher yield and better bean quality, and planting time of end April were recognized as the best treatments for Zarghan areas.

Optimization of Airports, gate scheduling is a vital activity. The main purpose of this optimization is to find a proper allocation for the flights arriving and departing by considering all of limitations. Studies show that the gate scheduling is applied for minimizing the gate flights delay and maximizing the gate efficiency and productivity. The optimization is formulated as a mixed-integer programming (MIP). The paper is studied data from Mehrabad International Airport. Our results show that the model can be solved by using NSGA-II algorithm in a short time. The set of Pareto solutions are ranked by TOPSIS method and the first 10 solutions are reported. The results show that although adding the first objective function (crowd congestion) leads to %8 reduction of the third objective function (the total gate assignment preference); the first objective function has a positive effect on the satisfaction of passengers.

Cage birds like canaries can potentially harbor human pathogens and contribute to transmission and spread of drug resistant infectious agents to human. Considering many people's interests to keep canaries, present study was conducted in canaries from Yazd to investigate the beta-lactam antibiotics resistant Escherichia coli. 109 E. coli isolates from canary faeces in Yazd were evaluated to investigate the resistance to beta-lactam antibiotics by disc diffusion method. Resistance of isolates to Imipenem, Cefotaxime, Cefixime, Cefalexin, Amoxicillin, Penicillin G and Oxacillin was 0%, 5.5%, 44%, 95.4%, 95.4%, 100% and 100% respectively. Canaries harbored beta-lactam antibiotics resistant E. coli and could be an important component of drug-resistant infections transmission from cage birds to human, especially kids and can pose a potential risk to human health in the region. It is recommended to make pet birds owners and general public aware of potential dangers of cage birds keeping.

Blood stream infection is one of the main causes of morbidity and mortality in patients with cancer. The purpose of this study was to evaluate the prevalence of aerobic and anaerobic-bacteremia in hospital inpatients with cancer and to determine the antibiotic resistance profile in isolated organisms in Kerman, southeast Iran. Total of 240 blood cultures from 136 patients were examined. The blood cultures performed in BACTEC media and were assessed for four weeks in aerobic and anaerobic conditions. Identification of isolates and antibiotic susceptibility test were performed by standard methods. 24.6% of blood cultures were positive. The prevalence of polymicrobial bacteremia was 12%. Forty-three out of 65 isolated bacteria (66%) were gram positive and others (34%) were gram negative. Coagulase negative Staphylococci (21.5%), Propionibacterium spp (15.4%), Diphtheroid spp (12.3%), and Escherichia coli (12.2%) were the dominant isolated bacteria. All Staphylococci were methicillin resistant. The only isolated Pseudomonas putida and 37% of isolated Escherichia coli were multi-drug resistant. A number of Streptococci, Klebsiella, and Alcaligenes spp were also resistant in part to the antibiotics. Patients with cancer may be readily infected by many opportunistic pathogens including multi-drug resistant strains.

Infection may be caused by transfer of bacteria from the hands of the surgical team during operative procedures. Therefore carefull surgical scrubbing is performed to reduce the number of bacteria on the skin. The duration of scrubbing and the antiseptic solution are two variables in this purpose. One hundered sample were removed from the index pulp of Right hand of the surgeons. At the time of zero, 2, 4, 6 and eight minutes after hand scrubbing with betadyn and brush. After incubation of the samples, culture results were reported. This study showed that 2 minutes scrubbing the hand by povidine iodine %7.5, would probably be enough to reduce the number of the bacteria of the skin.
