Abstract\n Background and Objective: Zarrineh Roud river which, is also named Cham Choghatoo is one of the most important and longest rivers of Euromieh Lake watershed area which, is originated from Kurdistan’s Chehel Cheshmeh Mountains and eventually pours into Euromieh Lake. One of its’ important usage is for drinking and farming which, unfortunately due to its’ pollution with different natural and man- made pollutant , makes the quality monitoring of its water under special importance and attention . In this study, we review quality of this river.\n Method: In this study we have measured 13 parameters of DO, FC, pH, BOD, changing in temperature, total phosphate, total nitrate, chloride, TDS, EC, Calcium, Sodium and Magnesium in two seasons of spring and winter of year 1389 (2011), then based on this, quality of water has been analyzed based on NSFWQI index and Wilcox method.\n Findings: In most of the times, in both seasons of spring and winter, amounts of NSFWQI index are in good range and only in two cases, in each season, index were in average range. Also based on results of Wilcox method in both seasons, majority of stations were at C2S1 range, in some cases also these amounts were at C3S1 range. Only in Station Ghale Bozorg in spring amount of salinity was in C4 range.\n Conclusion: In most cases, water of Zarrineh Roud is appropriate for farming, fish farming, animal drinking , leisure usage and drinking ( after normal filtering)

Abstract\nLiterary interaction of Persian-speaking countries and Attitudes of their poets in terms of science and research, has been of interest to researchers in recent decades and in many countries like Iran and Tajikistan have led to literary and linguistic sharing. Following the movement of Modern poetry, many Tajik poets including Farzaneh Khudjandi have been affected by Iranian poets, especially by Forough Farrokhzad. In this paper, after analyzing the background of contemporary poetry in Iran and Tajikistan, poems of Farzaneh Khudjandi and Forough Farrokhzad have been compared with each other. In this comparison the poems of two poets in terms of expression and linguistic, verbal and intellectual features, meter, content and theme have been reviewed. The theme of Foroughand Farzaneh\'spoems is reviewed in three levels of social - political, religious-ethical and emotional issues. Both poets, in terms of feminine feeling and emotion, the love and patriotism arein common and in terms of social – political attitude, man, the world, physical and heavenly love, despair and hopelessness and death are different. We see the use of literary technique as rhyme, metaphor, symmetry and intertextuality in the lyrics of Forough and Farzaneh. At the beginning, both poets had used classical meter and then Modern meter. Study and comparison of these two poets\' poems expresses that Farzaneh is deeply influenced by poem and thoughts of Forough.

Abstract:\n In most of the current design codes and standards for concrete liquid storage tanks, the hydrodynamic pressures are determined assuming that the tank walls are rigid. The Housner’s model, which assumes that the mass of liquid is lumped on the wall based on rigid wall boundary condition in the calculation hydrodynamic pressure, is widely used in practice. Previous research has indicated that the flexibility of wall can affect the distribution and magnitude of hydrodynamic pressures. In this paper, the effect of wall flexibility on hydrodynamic pressures in concrete rectangular tanks is studied using an approach referred to as the sequential method. The procedure on how to establish the impulsive hydrodynamic pressures using the sequential method based on a two-dimensional analysis is described. A comparison shows that the lumped mass approach overestimates the base shear and wall displacements.

In this paper, we will present some properties of bounds of the variance, the standard deviation and of the coefficient of variation. Several notions related to variance, standard deviation and the coefficient of variation for sample series are given.

The performance of medical image segmentation assessment is highly correlated with the extraction of anatomic structures from them, and the major task is how to separate the region of interests from the background and soft tissues successfully. This paper propose a fuzzy logic based bitplane method to automatically segment the background of images and to locate the region of interest of medical images. This segmentation algorithm consists of three steps namely identification, rule firing and inference. In the first step, we begin by identifying the bitplanes that represent the lungs clearly. For this purpose, the intensity value of a pixel is separated in to bitplanes. In the second step, the triple signum function assigns an optimum threshold based on the gray scale values for the anatomical structure present in the medical image. Fuzzy rules are formed based on the available bit planes to form the membership table and are stored in a knowledge base. Finally rules are fired to assign final segmentation values through inference process. The proposed new metrics are used to measure the accuracy of the segmentation method. From the analysis, it is observed that the proposed metrics are more suitable for the estimation of segmentation accuracy. The results obtained from this work shows that the proposed method performs segmentation effectively for the different classes of medical images.

Corporate governance is one of the most important issues to which has been paid attention by big companies due to the massive financial scandals of recent years. Corporate governance includes supervising the company management, separating the economic units from its ownership and protecting investors’ and benefiters’ rights. The research goal is to assess the relation between some corporate governance mechanisms and stock profitability. The research independent variables are: institutional ownership, ownership concentration and board size. The stock return is dependent variable. The research statistical society includes all investors who have visited Tehran stock exchange to buy and sell shares in 2012. The sampling is done randomly. The data collection is done using field and library methods by distributing questionnaires among 130 stock investors. Finally, according to the collected data, the research hypotheses are assessed and analyzed through descriptive and inferential statistics. The SPSS software is used to analyze the collected data.

Gekko is an animal, which has been used in Chinese traditional medicine for hundreds of years in the treatment of tumor, bacterium, convulsion and coagulation. In our previous work, anticancer activities of Gekko powder in xenografted sarcoma 180 in Kunming mice has been demonstrated. However, the effective components in Gekko were still not clearly understood so far.\n Aim: To explore the anticancer effects and underlying mechanisms of Gekko ethanol extract (GEE) in human hepatocellular carcinoma HepG2 cells and in H22 bearing mice.\n Materials and methods: GEE was obtained from Gekko powder by ethanol extraction. 3-(4, 5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assay was employed to evaluate the anti-proliferative effect of GEE in vitro. Hoechst 33258 fluorescence staining was performed to observe morphological changes of HepG2 cells. Antitumor properties of GEE were tested by intraperitoneal (IP) injection into H22 tumor bearing mice. After IP injections for 10 consecutive days at doses of 20 mg/kg (low dose, GEEL), 40 mg/kg (mid-dose, GEEM) and 80 mg/kg (high-dose, GEEH), the mice were sacrificed. Tumor weight of each mouse was evaluated. The expression levels of interleukin-6(IL-6) and tumor necrosis factor-α (TNF-α) in serum were analyzed by ELISA assay. Western blotting analysis was carried out to detect the expression levels of caspase-3 and VEGF in tumors.\n Results: GEE has anti-proliferative effect in a time-dose dependent manner, with inducing morphological changes ability in HepG2 cells. GEE resulted in significant decreases in tumor weight. The expression levels of IL-6 and VEGF were down-regulated, whereas the TNF-α and caspase-3 were increased after treatment of GEE in vivo. \n Conclusions: Taken together, these findings suggest GEE has significant anticancer activity in hepatocellular carcinoma in vitro and in vivo, which may be due to antiangiogenesis and induction of apoptosis.

The paper assesses the occurrence and the amplitude of the hazard phenomena in the South-West Development Region based on annual, monthly and daily extreme climatic values (temperature, precipitations, wind, and dangerous climatic phenomena) from all the meteorological stations situated in the study-area (1961-2007). \nThe authors selected the most significant meteorological phenomena for both warm (heat waves and positive thermal singularities, dryness and drought, heavy rainfall, thunderstorms, hail storms, strong winds, acid deposits and fog) and cold (temperature inversions and cold waves, blizzard, snow layer, frost and hoarfrost, sleet and snow-broth, ice deposits and winter heat waves) semester of the year in order to establish the main vulnerability classes (mixed, very high, high, medium and low). Each climatic hazard was represented by a layer in GIS format comprising the spatial distribution of its environmental vulnerability. Following the layers’ superposition and correlation, two complex climatic hazards’ maps, one for each semesters of the year have resulted in order to emphases the main threats of these hazardous phenomena on the environment.\nThe regionalization of climatic hazards has a practical importance for the human communities at regional and local level in order to diminish their negative impact.
