The current study was conducted to investigate the prevalence of Salmonella spp. in turkey and to determine the antimicrobial resistance pattern of the isolated Salmonellae. Two hundred and fifty turkeys were randomly selected for cloacal soab samples preparation, and the samples were investigated for Salmonella isolation. Identification of the isolated Salmonella was performed using standard bacteriological and biochemical procedures. The prevalence of Salmonella in turkey was about 14.8%. Disc diffusion tests on Muller-Hinton agar were used to determine the sensitivity to antibacterial agents. Ten antibiotics were studied: lincospectin, colistin, cephalexin, ciprofloxacin, chloramphenicol, gentamycin, furazolidone, streptomycin, co-trimoxazole (trimethoprim-sulfamethoxazole) and tetracycline. The highest resistant was observed against cephalexin (89.2%), tetracycline (86.5%), colistin (83.8%), and furazolidone (73%). The Highest sensitivity was found to gentamycin (86.5%), ciprofloxacin (83.8%), chloramphenicol (51.4%) and streptomycin (40.6%). The results showed high prevalence of Salmonella spp. in turkey and high levels of antimicrobial resistance pattern of the isolated Salmonellae were observed.

A field study was conducted at the Agricultural Research Farm of Razi University, Kermanshah, Iran to investigate the effects of phosphate biofertilizer, row spacing and plant density on corn yield and weed growth. The experiment was a factorial with three factors arranged in a randomized complete block design with three replications. The first factor was phosphate biofertilizer (inoculation and non-inoculation), the second was row spacing (conventional (75 cm) and reduced (50 cm)) and the third was plant density (66,666 plants·ha–1 (conventional plant density) 83,333 and 99,999 plants·ha–1 (1.25 and 1.5 times the conventional plant density, respectively)). Results indicated that corn yield and weed growth were significantly influenced by row spacing and plant density. So that, corn yield improved and weed biomass diminished in response to increasing plant density and decreasing row spacing. However, phosphate biofertilizer had no significant effect on corn yield, whereas, weed biomass was notably increased when phosphate biofertilizer was applied. Overall, this study revealed that both yield and weed control in corn field can be improved by alteration of the planting arrangement.

The objective of this research is to investigate the impact of infestation by the confused flour beetle Tribolium confusum on the specification of flour and its product. The results of this work showed that infestation by the confused flour beetle with 5 pairs of adult stage and its progeny within 3 months period may cause high deterioration and damaged of the flour specification. The people in lraq get their flour from some official and non-official mills which they produce not so good quality of this flour in addition to which it contains some times an infestation with the two species of the flour beetles T. castaneum and T. confusum, when people do not use this quantity as quickly as possible during this period of storage, the beetles will be increased in numbers and make the flour unacceptable for any kind of pastes or bread. The infestation by this beetle causes great pollution to the flour by the ecdysial of larvae and a bad smell that it leaves on the flour and all its products.

The general goal of the management of communication and information technology (MCIT) in the health sector, is to accelerate collecting, achieving and supporting the health system processes, and effective decision-making for managing this system;because preparing and providing health care services for society is very complex, and highly dependent on the information system. The aim of this investigation is to determine the mean scores of the possibility of implementing the MCIT standards in Khorasan Razavi hospitals, from the perspective of managers. This was a cross sectional descriptive-analytic study conducted in two steps in all hospitals. In the first step, the applicability of the standards in hospitals was studied. In the second step, the current status of hospitals was compared with international standards MCIT. In order to determine the validity of the questionnaires, opinions of professors and experts were acquired. Regarding the reliability, the SPSS V. 12 calculated the value of Cronbach’s to be 0.95 for the first questionnaire and 0.86 for the second questionnaire. Data were analyzed using statistic tests of one way ANOVA and t-test. The level of significance was fixed at 0.5. In the 16 hospitals studied, the mean and standard deviation of MCIT were (57.25 ± 13.74). The MCIT standards are applicable in hospitals of Khorasan Razavi according to half (49.4%) of managers;nonetheless, their application requires greater efforts by the hospitals.
