The main objective of the current proposed work is to emphasizes on the fact that there is a dire need to discover novel bionic shapes for the urban wind turbine rotors which would dovetail with the cornered flow patterns and thereby enable the capture of the high kinetic energy existing in the vicinity of the cornered flow past a building in an urban terrain. And this clearly affirms the effectiveness of the urban wind turbines and its utility as a renewable source rendering us with an alternative and superior way of electricity generation.

A major part of the civil engineering infrastructure will need significant repairs. The innovative rehabilitation and strengthening methods for reinforced concrete structures, especially with composite materials, has taken a large portion of the research work in the field of repair and restoration of structural elements. Also, some of these techniques were used to strengthen columns by confinement with composite enclosure. This paper investigates the strengthening of High Strength Concrete short circular columns using Glass Fiber Reinforced Polymer [GFRP] sheets. The main variables of the work are the slenderness ratio of the columns and the number of layers of GFRP wrapping. Column specimens of three different slenderness ratios [3, 6 and 9] each wrapped with 3 and 4 layers of GFRP fabric was considered for the study. Another set of unwrapped columns serves as the reference. The diameter of the columns is 150 mm. The columns were tested under uni-axial compressive loading until failure. The test results show that the load carrying capacity as well as the ductility capacity of the columns improved with the increasing slenderness ratio and number of layers of GFRP wrapping.

The present study aimed at studying the effectiveness of resiliency training on social compatibility and marital satisfaction of rehabilitating addicts. The population of the study included 120 rehabilitating marital addicts who have come to addiction- leaving center of Astaneh city in months of Mordad, shahrivar and mehr in 1391. Among 85 addicts who have filled the questionnaire form, forty nine of them had low social compatibility and marital satisfaction scores. Among these addicts 30 people have been selected randomly and placed in experimental and control group in a simple random state (fifteen in and group). Resiliency has been trained to experimental group during ten seventy-Five- minute sessions and both groups refilled out the questionnaire. By using covariance test the hypothesis of the study have been tested and the results of study showed that resiliency training influences on social compatibility and marital satisfaction of rehabilitating addicts. The present study reflects the fact that resiliency training can provide useful and new strategies in increasing the social and familial compatibility of rehabilitating addicts.

This study was conducted to evaluation of different sources of nitrogen and biologic fertilizers on yield and some yield components of coriandrumsativum.Split plot in RCBD was used as experimental design and main plot included 100% organic, 100% chemical, 75% organic + 25% chemical, 50% organic+50% chemical, 25% organic + 75%chemical fertilizer and sub plot included incubate application (Azotobacterchroococcum, Azospirilliumbrasilense) and non-application.All treats had lowest means by 100% organic treatment and values increased by using of chemical percentages. Inoculation had positive effects on treats although application of organic fertilizer increased inoculation effects. The end of experiment, we recommended 25% organic + 75%chemical fertilizer as best as treatment for Coriander culture at research area.

The present work was aimed to evaluate the effects of shot peening on the mechanical properties and the fatigue life of 5052- H34 aluminum alloy at different shot peening time SPT. Shot peening to full coverage (100%) was performed using carbon steel shots with an average shot size of 0.6 mm and at shot peening times of 10, 15, 20, 25 and 30 min. The 10 minutes shot peening time gave the highest value of ( ) which is about 9.489% for ( ) and 10.36% for ( ). The fatigue endurance limit was raised by 10.93% at 10 minute shot peening time and then reduction was observed.

The FT-IR and FT-Raman spectra of P-Chloroaniline (PCA) have been recorded and analyzed. The optimized geometry, and harmonic vibrational wave numbers of PCA have been investigated with the help of B3LYP scaled quantum mechanical (SQM) method supplemented with 6-311++G** basis set. The infrared and Raman spectra were predicted theoretically from the calculated intensities. The observed and simulated spectra were found to be well comparable. In the investigation, we adopted density functional theory (DFT) combined with quantum chemical calculations to determine the first-order hyperpolarizability.

Now a days in pharmaceutical cadre, multiparticulate dosage forms have shown much importance over single-unit dosage forms. The main objective of designing multiparticulate dosage form is to develop a reliable formulation that has advantages over single unit formulation. It is devoid of the danger of alteration in drug release profile and formulation behavior due to unit to unit variation. The present research emphasizes mainly on qualitative study of “Bottom-Spray Wurster Technology”, by formulation of multiparticulate modified release pellets of tolterodine- tartrate. The aim of the present study is to investigate the feasibility of the Wurster process for preparing modified release pellets and subsequently to evaluate the effects of some independent process variables i.e. inlet air temperature, product temperature, exhaust temperature, atomization speed, spray pump speed and atomization air volume.

This paper attempts to look at how information and communication technology continually influence the people, their lives and practices in general in developing countries, and examine whether it is for better or for worse. Dependency of low-income groups on information technology is not a mere phenomenon, but a solid hard-ground fact, and has a number of benefits as well as costs. However, at the end it is suggested that in addition to ICT being more advantageous than disadvantageous for third world countries, more effort needs to be put in educating the users of such technology, so that the costs associated with their use can be minimized, and the benefits maximized.

In this paper we introduce the new type of transportation problem called South east corner rule . We solve the transportation problem using OR approach in analysis ,design phases and we use the java programming language to model the problem . The results obtain from both solutions are compared to make analysis & prove the object oriented model correctness . We proved that the both results are identical & have the same results when solving the problem using the south east corner rule .

The effects of aqueous leaf extracts of different concentrations of Butea monospermal (Lam) Taub (Fabaceae), Limonia acidissima L. (Rutaceae) Semecarpus anacardium L. (Anacardiaceae) from Pathardi Tahsil (longitude190 09? N, latitude 750 10? E) Dist Ahmednagar were bioassayed in August 2008 on germination and seedling growth of Raphanus sativus L . var. ‘Hybrid 11’. Seed germination was promoted 13 to 21% by Butea, 3.58% by Limonia while Semecarpus inhibited by 10.71% at 10-1 concentration. Data was analyzed by appropriate statistical method. Inhibition at higher and stimulation at lower extract concentrations were recorded. Pot culture experiments will be arranged.
