Wind energy conversion system (WECS) is one of the most economical, flexible and efficient for generating the electrical power than other renewable energy sources. Self-excited induction generator (SEIG) and doubly-fed induction generator (DFIG) are used to generate the electrical energy from the wind through wind turbine. DFIG is most suitable in variable speed applications, because, better energy capturing can be achieved and the power is taken from both stator and rotor. In this paper, designing the proportional-integral (PI) controller, direct-torque controller (DTC), direct-power controller (DPC) and direct-current controller (DCC) and those controllers are incorporated in rotor circuit of DFIG. Performance of those DFIG controllers and impact its effect in the interconnected grid system are analyzed by PSCAD simulation software. Simultaneously, pulsation of DFIG parameters with network disturbance and harmonic behavior of DFIG stator current with those controllers, grid voltage have been described.

The current research is intended to study the relationship between factors influencing on capital structure and debt ratio of the firms listed at Tehran’s stock exchange. This research involves all firms with audited financial statements listed at Tehran’s stock exchange. It needs to be mentioned that the information has been considered in terms of firm – year mode so that if a firm was listed at Tehran stock exchange even for the first year, it would be considered in this research. The current research aims to investigate that relationship between firms’ profit management and the transactions of their dependent individuals. A post event approach was used. A correlation-descriptive methodology was employed with respect to the type of the relationship to be tested while the research is also considered as experimental one in terms of its objective. The required data has been collected by the information banks of the library for Tehran’s organization of Stock exchange since 1999-2010. In order to answer the research hypotheses, fitting regression models was used together with Durbin Watson’s Statistics and estimation of variance inflation Coefficients. Also, testing the analysis of variance for regression models were applied to determine the validity. The results from testing the hypotheses showed that regarding the outputs of the software, it could be argued that the hypotheses claiming the relationship between asset returns, accumulated profit, income volatility and firm size with debt ratio is confirmed at error level while other hypotheses claiming the relationship between shared profit policy, profitability, structure, firm’s growth , ownership structure and debt free tax deposit are rejected.

ABSTRACT\nAny service organization needs to provide high quality service to its customers, in order to achieve customer satisfaction, and survival in a competitive environment. The need to continually assess the quality of services in the service organization is undeniable. Since banks are for-profit firms, and in the competing today\'s market, the competition of public and private banks is entered into a new, differentiated stage for attraction costumers and increasing resources and benefits, customers need to be investigated in terms of new services which is among the most vital. The objective of this research is evaluation of Internet Banking Services of Bank Sepah, on improving customer service. To this end, it is used SERVQUAL model which is of the most famous and most applicable in evaluating service quality. This model assesses the quality of service, in 5 tangible dimensions: reliability, responsiveness, assurance, empathy. 385 customers were selected as the research sample, and questionnaires were distributed among them. The results show that in all dimensions, customer expectations are more than their perception about the actual services of Internet Bank in Bank Sepah.

The investigation of chemical compositions of Laurus Nobilis leaves showed that more than 70% of fatty acids compositions in this herb are unsaturated type. The predominant fatty acid in its extract is Linolenic acid which is 25.95%. Also, the recognition of chemical compositions of methanol extract of Laurus Nobilis leaves showed among Tocopherols, gamma and betatocopherol with 57.39%; among Sterols, beta sytostrol with 75.17% and among Tochotryanoly compositions identified, gama tochotryanol with 12.21% have highest values. The results revealed that the concentration 1600 PPM of the extract of laurus nobilis leaves, because of having higher Polyphenol and Tochopherol compositions with regard to inhibitory effects of free radicals on the stability of the canola oil, at comparison with other extract concentrations as 200, 400, 800 and other instances were more effective and at comparison with the synthetic antioxidant BHT, at concentration 200 PPM, has greater effect. The results of the oxidative stability of oils containing different extract concentrations also showed that the concentration 1600 PPM of the extract of laurus nobilis leaves has higher performance, in increasing of the oxidative stability index, than other concentrations and synthetic antioxidants BHT which naturally this oxidative stability is related to more amount of Tochopherols and phenolic compositions of extracts.

ABSTRACT\nBackground: Individuals who are making agriculture and animal husbandry for livelihood are faced with a variety of physical and psychological health risks. In many studies conducted around the world it has been shown that these risks turn into diseases.\nAim: This study is aimed farmers\' physical, mental, and social health status were examined through comparison according to their socio-demographic characteristics in Kars province. \nStudy design: Cross-sectional \nMethod: In this study, 177 farmers’ bio-psycho-social health status were examined cross-sectionally in11 central villages of Kars where agriculture and animal husbandry is the most common in Turkey. For the interrogation of the physical and social health, 38-item questionnaire consisted of open-ended and closed-ended questions were used. Mental health evaluation was performed using 21-item Beck Depression Inventory. \nResults: Depression rate 62.1%, physical health problems 52.0%, socially unhealthiness 53.7%. There was statistically significant difference between depression scales cores and age, education level, number of children, physical conditions of the house and physical health status. There was significant difference between body health and age, education level, number of children, social and mental health. There was connection between social health and education level, body health but no connection was found between mental and social health. \nConclusion: In the light of these findings, it is easier to understand the socio-demographic characteristics and health conditions of farmers. It is thought that this study will contribute considerably as data-based evidence to planning protective-developer public health and veterinary services for the needs of the region.

Lilium martagon is a perennial geophyte species belonging to large Liliacea family. Its population is at the status of ‘’VU’’ in “Red Data Book of Turkish Plants”, and along with many European countries, it is included in Turkey’s list of the plants that are endemic and under the state of being imperiled.\nThis study analyzed the potential of producing Lilium martagon with clove. Four different hormones (IAA, IBA, NAA, and GA3) were applied in three doses (1000 ppm, 3000ppm and 5000 ppm) and after 120 days, 6 morphological characteristics were determined. According to the results, 1000 ppm IBA implementation is seen as the most effective hormone dose implementation on morphological characters. According to the effect of fraction position, for all characters, the individuals formed by the pieces taken from the bottom parts of clove are included in first homogeneous group. Also, it is revealed that each of the apical, medium and basal parts obtained by cutting nail-like scales on the corpus in 3 equal pieces have potential meristematic reproduction ability.

Cervical and mediastinal hemorrhaging caused by a spontaneous rupture of a parathyroid adenoma has been rarely reported. Herein, we report a case of a 52-year-old woman who experienced a sudden onset of cervical and mediastinal bleeding related to a parathyroid adenoma. The patient had a history of trauma to the left thorax with a fracture of two ribs. Ultrasonography and computer tomography revealed a nodule in the retrotracheal space and hematoma of the bilateral trachea and thorax. Laboratory examinations revealed significant hypercalcemia, hypophosphatemia, and a high level of intact parathyroid hormone. Surgery was performed and a dark-red, soft tumor was found behind the trachea, which adhered to the surrounding tissues. The pathological diagnosis was a parathyroid adenoma with hemosiderin deposition and fibrosis.

Background and Objectives : With the increasing use of medicinal fungi and its effect on medical treatment, this branch of alternative medicine as antimicrobial additives have an important role in maintaining food quality. This study is aimed to determine the antimicrobial effects of aqueous and alcoholic extracts of macroscopic fungus Clitocybe brumalis.\nMaterial and methods: In this experimental study, during 2010-2011 (late fall and early winter in Zahedan and Khash), the stage of collecting the macroscopic fungus has been done, and then all samples have been examined in the microbiology lab of Islamic Azad University of Zahedan. At first, the bacteria were prepared from pure culture, and also the aqueous and methylen extracts have been prepared in the soxhelt apparatus. The effect of the concentrations of 1/0, 2/0 and 3/0 mg/mL were studied on bacteria Proteus volgaris, Salmonella typhimurium, and Staphylococcus epidermidis using the disk diffusion method, as well as minimum inhibitory concentration (MIC).\nResults: Certain concentrations of fungus extracts have antibacterial effects on some microorganisms. Although Effect of alcoholic extract was reduced by decreasing the concentration, the aqueous extract was reverse mode. The results indicated that aqueous and alcoholic extracts of Clitocybebrumalis contain compounds with anti-microbial properties. Study on Antimicrobial activity of macroscopic fungus extracts is a way to find new crucial combinations of microorganisms. \nDiscussion: indicated that the alcoholic extract effect (80% ethanol) of fugues Clitocybe brumalis on the bacteria Staphylococcus epidermises, Proteus volgaris and Salmonella typhimurium resulted in a clear halo. But in gram positive bacterial species diameters of halos at three different dilutions (0.1, 0.2 and 0.3) aqueous fungus extract haven\'t shown any antibacterial effect against gram-negative bacteria and also we noticed that the alcoholic extract has a direct effect on the bacterial species, while aqueous extract has less effect on the bacterial species.
