Comparison of the effect of balance training methods of core stability, plyometrics and their combination on static and dynamic balance in female futsal players
This study aimed to compare the effect of balance training methods including core stability, plyometrics and their combination on static and dynamic balance in female futsal players. To this end, a number of 60 female futsal players from Shahrekord city were selected as the participants using purposive sampling method. Then the subjects were randomly assigned into four groups each with 15 members including three experimental groups (core stability training (N=15), plyometric training (N=15) and combination training (N=15)) and a control group (N=15). Height, weight and leg length were measured in the subjects. In the pretest, the subjects performed Stork Test and Star Excursion Balance Test (SEBT) to examine their static and dynamic balance performance, respectively. Based on the training protocol, the experimental groups did 8 weeks of their assigned exercise training. The training sessions were held three times a week and 45 minutes per session. The control subjects performed their routine trainings. After eight weeks, all variables were measured in the four groups again. Paired t test was run for within-group comparison, and one-way ANOVA was used for between-group comparison. The results showed that combination training group achieved the best performance in both static and dynamic balance comparing with other groups. Based on the present findings, it can be concluded that a combination of core stability and plyometric exercises may improve static and dynamic balance in female futsal players. Thus, it is recommended that these exercises be included in training programs for futsal players.

Cross Layer Design Approach for avoid Congestion Control in Wireless Mobile AD-HOC Networks
Multi-hop Wireless Networks (MHWNs) are anticipated to play an important role at the edge of the Internet, enabling a large number of innovative applications. The great demand for capacity from a large number of users and applications, coupled with the sparse bandwidth available on the wireless channel, place particular emphasis on effective congestion management approaches. Effective and well-studied algorithms for congestion control at the transport layer exist in wired networks. However, for a number of reasons, these approaches do not translate directly to wireless environments. In this chapter, we first describe the problem of congestion control in MHWNs, and discuss approaches for solving it. The presentation is organized into two components: (1) a review of the causes of congestion and algorithms for congestion avoidance in MHWNs at different layers of protocol stack; and (2) a review of analytical models for the rate control problem and their use for congestion control.

Design and Analysis of End Ring for processing Solid Rocket Motor Segments
Solid rocket motors are produced in the form of segments which are used as boosters in the launch vehicles. To produce any rocket segment, hardwares are subjected to a series of operations. The rocket hardwares are thin cylindrical shells which are very sensitive to the externally applied loads. During production, a number of handling operations are essential. A suitable interface is to be generated to cater to the production operations. These requirements are met by connecting a circular ring called End Ring to the hardware using the available hardware interfaces. This paper deals with Design and Analysis of HES Dome Side End Ring for Head End Segment.

Dielectric Confinement on Exciton Binding Energy in a II-VI Semiconductor
Exciton binding energy is obtained in a ZnxCd1-xTe/ZnTe strained quantum dot taking into account the phonon confinement effect. The effect of mismatch between the dielectric constants of the dot and the barrier (dielectric mismatch effect) is taken into account in our calculation. The calculations include the effect of exciton and the LO phonon interaction is derived by the effective potential (VPB) between the electron and hole along with the self energy term (Eself). It is observed that the potential taking into account the effects of phonon makes the exciton binding energies more than the obtained results using a Coulomb potential screened by a static dielectric constant and the optical properties of exciton in a quantum dot are strongly affected by the confining potential and the quantum size.

Environmental Stable Isotope Studies of Groundwater in the Accra Plains
The environmental stable isotopic (oxygen-18 and hydrogen-2) composition of groundwater in the crystalline geological formation underlying the Accra Plains of South-east Ghana were studied to obtain information on the recharge process. The groundwater had an average isotopic value of –3.19‰ ?18O and –14.36‰ ?2H. The groundwater recharge takes place in fractures with the occurrence of minor evaporation. The groundwater was also affected by the mixing of various rainfall events and or surface runoff. The groundwaters at Valley View University were more depleted than the other groundwaters in the Plains indicating that the groundwater was recharge at the Akwapim Togo Mountains through preferential channels.

Evaluation of four Trichoderma spp. for the biological control of Black bundle disease (Cephalosporium acremonium) in maize
Four Trichoderma species with known biocontrol activity (T. harzianum, T. hamantum, T. viride and T. virens) were tested for their efficacy against Cephalosporium acremonium, a causal organism of Black bundle disease in maize. Interactions between the fungi were assessed in vitro to study mutual antagonisms. Among the four bio-agents, T. hamantum proved to be promising which showed maximum inhibition (51.3%) followed by T. virens (45.2%), T. harzianum (44.6%) and T. viride (20.3%). T. hamantum was also found to be hyperparasite on C. acremonium whereas, T. harzianum and T. viride showed mycelial deformation. The volatile toxicants released by all the Trichoderma spp. were inferior in inhibiting the growth of C. acremonium when compared to the control as evident by inverted plate technique. The results of in vivo experiments confirmed the results from the in vitro study and showed that all the four bio-agents significantly reduced the disease incidence of Black bundle disease.

Experimental evaluation of a VCR diesel engine performance fueled with methyl ester of rice bran oil
In the world, day to day increases consumption of energy with increase the production rate of automobile. With the current consumption rate if it has been quoted that there will be great shortage of petroleum products in upcoming decades. For this reason research is going on alternative fuels. It is better to develop the engine which can work on bio diesel and one can add methanol in the bio diesel and use the blends of that. For this purpose, it is necessary to check the performance characteristics of the blends with the conventional diesel fuels.In this investigation, rice bran methyl ester was used in four stroke, single cylinder variable compression ratio type diesel engine. Tests were carried out at different injection pressures with various blends of rice bran methyl ester. The results proved that the use of bio diesel (produced from rice bran oil) in compression ignition engine is a viable alternative to diesel.
