Renewable energy does not pollute the environment and it has an endless and free primary source and save fossil fuel reserves for future generations. Finding and confirming the appropriate potential areas for installing wind turbines is the first and the most important step for constructing wind power plants. Hence, installing a standard anemometer station and checking wind flow regime is essential. In this paper, statistical characteristics of wind speed and direction and the parameters of Weibull function probability distribution were determined and then the potential and density of the wind power were calculated in Baladeh. The results showed that this place was classified in second power class under world classification and it has a relatively good condition for the installation of wind turbines, especially in warm seasons. © 2011 Academic Journals.

In today's environment of global competition where each company is trying to prove itself better than its competitors, software company have to continually do up-gradation or add-ons in their software to survive in the market. Each succeeding up-gradation offers some innovative performance enhancement or some new functionality etc distinguishing itself from the past release. But at the same time the amount of risk involved in up-gradation/add-ons of software with regard to introducing new faults or increasing the fault number in the software is also formidable. This model categorizes faults in two types: Type-1 and Type-2 (simple fault, hard fault namely) with respect to time which they take for isolation and removal after their observation. In this paper, we propose new model and new concept of multi release software development environment. The model developed is validated on real data sets for software which has been released in the market with new features. © 2011 IEEE.

Herbs have a special place in drug treatment. In this study, the essential oils and composition in Dracocephalum Kotschyi province were studied at three habitates in mazandaran province. Vegetation through field surveys and random sampling and transect - plot took. The essence of the shoots Dracocephalum Kotschyi in three habitates of mazandaran collected. Compounds in the essential oil analysis chromatogram and average of Dracocephalum Kotschyi in studied areas by Pearson correlation coefficient was calculated using SPSS software. Results showed that the highest yields in the plant height of 2800 meters above the summer pastures. Also, Most of the isolated compound in hezar jrib area for alpha-pinene (23,73%) and the lowest percentage of silosifon (1 percent). This is while the highest combined in gadok savadkooh for alpha-pinene (22,16%) and the lowest percentage of trans oksidlimonen (1,12%) and in balade noor, the largest percentage of limonene (46, 75%) and the lowest for cyclohexene compound (1,01 percent).

Prioritizing and expanding the agricultural activities by increasing the agricultural commodities are the strategies to create a balance between the increasing population rate and food production to meet the increasing needs of human beings. The existence of suitable water and soil are the main factors for these activities. In this study the influence of changing the exploitation of pasture system to farming land system on the physical and chemical properties of the soil in one selection in Sajadrood catchment in the north of Iran was investigated. Samples were taken at two depths (0-10 cm and 10-20 cm) in four sites. After experimentation, the gathered data were analyzed using SPSS 21.0 software program. The results showed that the amount of soil bulk density, amount of organic carbon and the percentage of clay were increased in farming lands in comparison with pasture. In pasture with the depth increase, there is a reduction in acidity and percentage of the moisture saturation percentage, but there is an increase in the amount of neutral substances and the percentage of clay, with the depth increase (10-20 cm). Generally, in most sections, the amount of physical and chemical change in farm lands by changing the use is lower than pasture. © 2014, Agric Eng Int: CIGR Journal. All rights resereved.
