  The objective of this study was to measure Technical Efficiency (TE), Allocative Efficiency (AE) and Economic Efficiency (EE) in Caspian cattle feedlot farms. In this research, 70 farms were selected and efficiency estimated by Data Envelopment Analysis (DEA) approach. The results showed that for the case of Constant Returns to Scale (CRS), mean technical, allocative and cost efficiencies were 67.66, 80.57 and 53.5%, respectively and for the case of Variable Returns to Scale (VRS), mean technical, allocative and cost efficiencies were 87.23, 74.87 and 65.90%, respectively. crsTE were significantly affected by farm size (p<0.05). vrsTE were not significantly affected by farm size (p>0.05). crsTE and vrsTE were not significantly affected by farmer’s age, farmer’s education and farmer’s experience (p>0.05). On the basis of results of this research, we can improve efficiency of Caspian cattle feedlot farms by correct using of production inputs, such as increasing length of fattening period, decreasing farm size and decreasing metabolizable energy and crude protein intake of calve.

  Whatever a hive with high population inter a season of collecting nectar the rate of produce honey will increase as well. To provide energy needs in times of nectar shortage in nature, artificial nectar should be used to replace natural nectar, In order to assess the effects of different levels of nutrition, persimmon sap used as a stimulatory nutrition on laying queen bee rate in the colony in spring 2011, This experiment were conducted based on Completely Randomized Block Design (CRBD) with 5 treatments and 5 replications in wild land in Guilan province on (Apis mellifera). To reduce genetic disorders sister queen with the same age were used. Treatments 1, 2, 3, 4, and 5 were sugar and water syrup 1:1; persimmon sap and water, 3:1; persimmon sap and sugar, 1:2; persimmon sap and white sugar, 1:1 and persimmon sap and sugar, 2:1, respectively. Treatments were used for 60 days. Amount of laying by queen was measured by determined scale. Related data to influence of nutrition on laying of queen showed that there was a significant difference between control treatment and experimental treatment (p<0.05). The most amount of laying was belong to treatment 4 and the least amount was observed in treatment 2.

Aim

To evaluate the association between health-related quality of life and glucose metabolism status in a study population in Qazvin, Iran.

Methods

This cross-sectional study was conducted in 1044 people (aged 20-78 years old) between September 2010 and April 2011 in Qazvin, Iran. An oral glucose tolerance test was performed for each participant who had never been diagnosed with diabetes. Participants were characterized as having normal glucose metabolism, pre-diabetes or diabetes according to American Diabetes Association criteria. The short-form 36 questionnaire was used to measure quality of life. Data were analysed using a chi-squared test, anova and ancova.

Results

A total of 530 (51.7%) of the participants were women, and 24.1 and 11.6% of the participants were categorized as having prediabetes and diabetes mellitus, respectively. Except for the role emotional domain, there was a gradual decrease in the mean scores of every domain of the short-form 36 scale across the three study groups. The mean scores in the physical domains were significantly different among the participants with normal glucose metabolism and those with diabetes. After adding age as covariate, there were no significant differences between the categories in any of the domains.

Conclusion

There is no association between quality of life domains and glucose metabolism status in Iranian subjects. More longitudinal studies are necessary to investigate the natural history of pre-diabetes, diabetes and quality of life.

  This research examines the factors that can speed up the successful implementation of electronic banking innovations in the Iran’s country. Through the literature review, the factors affecting the successful implementation of e-banking in Iran have been detected and classified into a tri-radiate model of co-structural, content and context factors. After collecting the questionnaires which were distributed randomly among experts and IT managers of 90 banks, the data analysis revealed that there is a meaningful and significant relationship between these three factors and the successful implementation of e-banking in Iran. Using Friedman analysis of variance test, the co-structural factors got first rank, context factors as second and the content factors the third rank, respectively. Mean while, the influencing factors on implementing e-banking were classified and ranked. Finally, some recommendations have been proposed to develop and reinforce the affecting factors bound up with implementing e-banking.

  Genetic variability was studied on five Iranian native chicken populations using Random Amplified Polymorphism DNA (RAPD) markers. The purpose of this study was for the analysis of variation within and between Iranian native chicken populations and for the reconstruction of a phylogenetic tree for these populations using the RAPD marker assay. The populations surveyed were from five provinces including Mazandaran (MZD), Isfahan (ISF), Yazd (YZD), Fars (FRS) and West Azerbaijan (WAZ). On the base of results of this study, the FRS and MZD populations had the highest genetic distance (0.182) and the FRS and ISF populations the lowest one (0.066). The YZD and MZD populations had the highest (0.208) and lowest (0.156) within-population genetic diversity. The phylogenetic tree was reconstructed on UPGMA method and showed two main separated groups. The ISF and FRS populations were first clustered into one group and, then, were clustered into a larger group with YZD and WAZ. Another consists MZD population was clustered separately from this group. This study showed that RAPD technique is an useful tool for evaluation of genetic variation among domesticated animals.
