  The Angoumoise grain moth, Sitotroga cerealella(Olivier), is a polyphagous and cosmopolitan species. This pest is distributed in Iran and all over the world. In this research, the effect of UV-irradiation was investigated on the biological parameters of S. cerealella. The 1, 2 and 3-days-old eggs were exposed to UV-irradiation (254 nm wavelength) for 0.5, 1, 2, 3 and 4 minutes at temperature of 27±3ºC, a photoperiod of 10: 14 (L: D) and 60±5% relative humidity. The results indicated that all exposure periods of UV-irradiation reduced percentage of hatching eggs. An increase in time of exposure to irradiation caused a gradual decrease in percentage of hatching in all age groups of eggs. It was observed that 2 and 3-days-old of S. cerealella eggs were more sensitive to UV-irradiation than 1-day-old eggs. Percentage of hatching eggs was 88.33% in control. However, hatching were inhibited up to 35.83, 3.33 and 18.33, respectively by 4 min exposure of 1, 2 and 3-days-old eggs of S. cerealella to UV-irradiation. At 2 and 3-days-old eggs, all exposure periods of UV-radiation increased significantly the incubation period of eggs of males and females in comparison to control. Adult longevity of females originating from 2 and 3 days-old treated eggs decreased significantly in comparison to control. However, in all age groups of eggs, no significant difference was observed between adult longevity of males in treated eggs and control. Manuscript profile

  Considering the growing trend of the consumption of the electric power and the global tendency to substitute new renewable sources of energy, this paper proposes a Monte Carlo based method to determine an optimal level of this change. Considering the limitation of the wind farms in continuous supply of electric power, hydrostatic power storage facilities are used beside wind farms so that the electric power could be stored and fed in a continuous flow into power systems. Due to the gradual exclusion of conventional generators and 5 percent annual load increments, LOLE index was used in order to calculate the amount of the  wind power and the capacity of the necessary power storage facility. To this end, LOLE index was calculated for the first year as the reference index for the estimation of the amount of wind power and the capacity of the storage facility in consequent years. For the upcoming years, calculations have been made to account for the gradual exclusion of conventional generators in proportion to load increments. The proposed method has been implemented and simulated on IEEE-RTS test system. Manuscript profile

  Many Studies indicated the effect of environmental factors stress such as heavy elements, harmful radiation, acid rain, salt etc. on the plants, but noise stress in plants has rarely studied. Audible sound wave technology has recently been applied to plants at various physiological growth stages e.g. seed germination, callus growth, endogenous hormones and mechanism of photosynthesis and transcription of certain genes. The aim of this research was survey effects of sound waves caused by railway transport on anatomic structures of Centaurea cyanus (Centaurea hyalolepis Boiss) and Marian thistle (Silybum marianum L.). Free hand sections were taken and stained in carmine and methyl blue. Thin cut sections were observed under the research microscope (Olympus) fitted with digital camera and attached with computer. The evaluation of cross-sectional, anatomy of plant tissue was done through taking micro-photographs. Our results indicated that remarkable changes has been seen in the anatomic structure of stem treatment plant in comparison with control plants such as increasing the chromaticity of cambium layers, enhancing the thickness of the sclerenchyma bundle sheath in the xylem tissues and improving the collenchymas layer of hypodermis. The sound waves of railway transport may increase of diameter and number of cell stability tissues (Sclerenchyma, collenchyma) stem of plant. Anatomical structure of plants, under the influence of the sound waves and noise pollution caused by rail transportation as an environmental stress changes fitted plants tissues. Manuscript profile

  Background & Objectives: Oil pollutions are one of the major problems threatening environment. Biodegradation using hydrocarbon-degrading indigenous bacteria is considered as a convenient method both economically and environmentally. The genus Alcanivorax is known as a petroleum hydrocarbon degrader in petroleum-contaminated marine environments. The purpose of this study was to evaluate the capacity of Alcanivorax dieselolei, isolated from the coastal sediments of Persian Gulf for crude oil biodegradation. Material & Methods: In this applied-fundamental study, first oil degrading bacteria were isolated from the coastal sediments of Persian Gulf and were enriched in media. The isolated bacterium was identified using molecular identification based on 16S rRNA sequence. The oil degrading ability of the isolates was assessed using various concentrations of crude oil. Results: Based on molecular approaches the isolated bacterium was identified as Alcanivorax dieselolei. This bacterium was able to disintegrate oil droplets stably in less than one minute. Results showed that the biodegradation rates at 1, 2.5 and 5% concentrations of crude oil were 68.37, 67.97 and 13.2% respectively. Conclusion: Since Alcanivorax genus is an indigenous bacterium in hydrocarbon polluted marine environments and its capability in biodegradation of crude oil has been proved, using this bacterium to remove oil pollutants is certainly possible.

  Argyrosomidae family and the species Argyrosomus hololepidotus due to high valued protein are among the most valuable aquatics in the Persian Gulf, Oman Sea and the coasts of Khuzestan. Lymphoid tissues are of the most important tissues in fish which their identification is important in health and disease states. Unlike mammals, fish lack lymph node and also there is not hematopoietic tissue in their bone marrows, and so mainly Hematopoiesis is done in their spleen and kidney. In this study, 6 pieces of Argyrosomus hololepidotus were provided from the Persian Gulf. Some samples from the spleen up to 5mm thickness were prepared and fixed in 10% buffered formalin. Then tissue sections were prepared in 5-6 μ and after HandE staining, the structures of the capsule and parenchyma of pronephrose were studied histologically. In order to confirm the results and findings of this staining, silver staining was also used. Microscopic results showed that tissue structure of Argyrosomus hololepidotuspronephrose was consisted of hematopoietic tissue, lymphoid tissues and kidney tubules. Pronephrose lymphoid tissues are also consisted of reticular supportive tissue and lymphocytic parenchyma cells. Manuscript profile

  با توجه به روند جایگزینی نیروگاه های سنتی با نیروگاه های تجدید پذیر در شبکه های قدرت مدرن، در این مقاله آلگوریتمی ابتکاری مبتنی بر قابلیت اطمینان برای این منظور پیشنهاد شده است. در ابتدا شاخص LOLE سیستم بدون ظرفیت توان بادی محاسبه و به عنوان شاخص مرجع انتخاب گردید. سپس به بررسی جایگزینی واحد های توربین بادی به جای نیروگاه های سنتی پرداخته شده و در هر مرحله، از تولید ظرفیت سنتی کاسته، و ظرفیت تولید توان بادی جایگزین آن گردیده است. میزان ظرفیت تولید توان بادی مورد نیاز برای جایگزینی مناسب، با اتکا به روش مونت کارلو و از مقایسه شاخص LOLE در هر مرحله با شاخص LOLE مرجع، بدست آمده است. در آخر، روند رشد بار 5% در استراتژی توسعه با تمرکز صرف روی تولید بادی بررسی شده و میزان تولید مورد نیاز به ازاء هر رشد بار معین تعیین گردیده است. روش پیشنهادی بر روی شبکه IEEE-RTS پیاده سازی شده است Manuscript profile
