Abstract
Occurrence of drought stress at the end of the wheat growing season (grain filling stage) is one of the most common stresses in the Khuzestan province. At this stage of plant growth, on one hand rainfall and water resources are reduced and on the other hand temperature and crop water requirement increase. At this stage using drainaged-water of the farms (saline water) for irrigation could be a suitable solution. First the SALTMED model was calibrated and verified by using the data from field experiments and then it was used to simulate effect of saline water (drainage ed-water) on the wheat yield and accumulation of salts in the soil profile. Model evaluation results showed that the model is reasonably able to simulate the effect of saline water on wheat yield and accumulation of salts in the root zone soil profile with a good performance. The values of evaluation indices of RMSE, MPE, D-index and r2 between simulated and measured yields were 409 kg, 5%, 0.84 and 0.99, respectively and the values of cited indices between the soil salinity simulated by the model and the measured soil salinity were 1 dS/m, 12%, 0.89 and 0.92, respectively. The simulation results showed that in the case of restriction of irrigation water (non-saline) at grain filling stages (no irrigation water restrictions in the early stages of growth), the saline water with EC≤4 dS/m can be used in heavy soils (loam - clay) and the saline water with EC≤6 dS/m can be used in light soils. Whereas farms have appropriate drainage canal and the leaching water requirement should be considered for leaching salts before the start of the next cropping season.

Abstract
In today's world, life of many industries depends on their ability in increasing precision of cost management system, which concentrates on decreasing cost or, in more general worlds, actual cost items as an important component of elements on survival triangle in the whole production process and value chain. In this regard, banking profession has unique characteristics compared with other economic activities. This characteristic is revealed considering both parties of balance sheet of a bank. According to their fundamental activity which is accepting deposits and making loans, banks are obliged to present services of both sides of balance sheet elements. In other words, a bank constantly tries to design and apply novel instruments for both sources (left-side of balance sheet) and consumption (right-side of balance sheet). Such a characteristic requires spending high costs and needs strong management power. Combination of spending high costs and achieving proper level if profiting leads banks to consider the necessity of designing and applying instruments and techniques for cost management more than before. Accordingly, managers of pioneer banks have paid more attention to their management in recent years through changing approaches and controlling costs. In this study, attempts were made to investigate effect of strategic cost management approach on key indices of performance of Tose'e Ta'avon bank, branches in Zanjan province as a case study. Statistical population of this study included managers and employees of this bank. Methods and instruments for analyzing the test data were mean via structural equations. The results showed that quality, price and performance as strategic cost management instruments affect key indices of bank including information and technology, customer-orientation and managing resources and consumption.

Kobra Nodehi* and Zeynab taghinezhad

Abstract
In When the Mongols invaded Iran, one of the hardest and bitterest eras of the history of this country was occurred. After Mongol Aylghar, the social, political, cultural and religious situations of Iran changed. After the devastating Mongol invasion, Iranian community, that had already a poor situation, collapsed from within more than ever so that these damaging effects stayed there for several centuries. Hafiz, as one of the bright stars in the sky of Persian literature, lived in such tumultuous times. Since he witnessed a lot of turmoil and depravity of his time, these situations and events have been reflected in his poetry in detail, so that it can be said that his poetry fully mirrors his time. This article seeks to demonstrate the expression manners of enjoining and inhibiting the obscenity in the view of Hafiz.

Fatemeh Sadat Tahami

Abstract
Since cyanobacteria are the base of life and productivity of aquatic ecosystems, sustainable ecological study of the Caspian Sea, particularly the distribution and identification of species composition, density and biomass, seasonal and regional variations in cyanobacteria before each study seems necessary.Plankton is strongly affected by numerous pesticides and herbicides. Synthetic detergents are very toxic for marine life, and water pollution with this agent affect the microbial flora. Marine life is easily affected, but the most deaths are due to lack of oxygen in the polluted water, and dumping of pesticides and toxic residue.Therefore, the purpose of this work was to study cyanobacteria of different seasons.For maturing of cyanobacteria Factors, choose 6 line Lisar, Anzaly, Sefidrood, Nooshahr, Babolsar and Amirabad that every line have 4 stations(A, B, C, D) and water for analysis have taken from different deeps ( 0,5,10,20,50,100) meter in southern of Caspian sea and then transferred to laboratory of Caspian sea ecological institute. Then the samples transferred to laboratory of Ecological Academy, kept in cool and darkness in properly capped glass bottles. The cyanobacteria was analyzed on a “Nikon” light microscope at ×480 magnification. Algae abundance was determined using the Hydro bios counting chamber and sampled (volume 0.1 ml).The volume of each cell was then calculated by measuring its appropriate morph metric characteristics and geometric. Finally, the volume values were converted to biomass. In this study, cell abundance and biomass of in different seasons were significant different. The dominant cell abundance was recorded in spring while the minimum were in winter. Shannon-Weaver diversity index (Shannon et al., 1963) of species ranges from 0.00 to 0.696 that belong to Oscillatoria tenuis.Ecological and environmental alterations may trigger changes in the cyanobacteria species number, abundance and biomass. Then, since cyanobacteria depend upon certain conditions for growth, they are a good indicator of change in their environment. For these reasons, and because they also exert a globalscale influence on climate, cyanobacteria are of primary interest to oceanographers and Earth scientists around the world. Algae and produce the bulk of primary production in seas. During this study, Cyabobacteria community in the Caspian Sea changed in different years and the maximum cell abundance and biomass observed in summer and Shannon-Weaver diversity index changed in this study.

Influence of short-term exercise on Reelin synthesis in the postnatal cerebral cortex of rats

1110-1112Full Text

Farzam Sheikhzadeh Hesari* and Elham Karimi Sales

Abstract
Reelin is a large neuroprotein which synthesized and secreted by GABAergic interneurons in adult cerebral cortex. This protein is vital for neuronal migration and development of the brain cortex in embryonic period. In adult period, Reelin induces dendrites generation, dendritic spines formation and so increases plasticity. Exercise has positive effects on brain structure and function. Some types of exercise can improve long-term potentiation, neurogenesis and plasticity. Present study investigated the effects of two weeks of treadmill running exercise on Reelin protein concentration in the cerebral cortex of adult male rats. In this study twenty male rats with 200±50 g weight were randomly divided into two groups; Test group that treated with two weeks of running exercise and control group without any training program. Rats of test group ran for 60 min /day at 22 m/min, 5 days/week on treadmill. After training period, all animals were deeply anesthetized and killed with rapid decapitation. Then brain cortex was immediately removed and concentration of Reelin protein in the cerebral cortex were measured by ELISA assay. Results shows that forced exercise could not significantly affect concentration of Reelin protein in the brain cortex of adult rats. This study suggested that treatment with short-term regular exercise could not affect Reelin protein synthesis and secretion by GABAergic interneurons of the brain cortex.
