While since a rather long time ago teacher feedback has received a lot of attention in learning a foreign language, quite recently, a gradual but prominent shift has taken place within the field of education, resulting in greater emphasis on learners and learning and less stress on teachers and teaching (Hismanoglu, 2000). An outcome of this event has been more emphasis on language learning strategies (Oxford, 1990). As another sign of increasing emphasis on learners, many studies have focused on the use of journals in EFL classes (Park, 2003). However, the present researcher failed to find any published research on how teacher feedback on EFL students’ journals can contribute to strategies they use for learning English as a foreign language. Thus, this study was conducted to explore contributions of teacher constructive feedback on Iranian EFL students’ journals to their use of language learning strategies. A group of EFL learners received a 3-month treatment of feedback-based journal writing and a control group did not receive any treatment. Prior to and following the treatment, the SILL was administered to the groups. Then, they were required to write journals which were followed by teacher constructive feedback for eight sessions. Pertinent statistical analyses showed that feedback-based journal writing does not have any significant effects on the use of learning strategies by EFL learners. However, longitudinal studies are suggested so that further realities of mental processing can be explored.

Dynamism pumps the blood to the body of society; therefore, the dynamic and communicative nature of language can not only be considered integral in teaching, but also in assessing a language. Recently, all over the world traditional ways of assessment are trading place with more communicative ones. The primary purpose of this study was to investigate whether dynamic and formative assessment had significantly different impact on improving the listening skills of Iranian EFL Learners. To do so, 90 intermediate male and female learners from a language school in Tehran were elected. A piloted PET was administered as homogeneity test and 60 learners were selected as the participants and randomly assigned into two groups of thirty. To make sure that there is no statistically significant difference between the performances of the two groups in the beginning of the research a listening pretest of PET was administered in both experimental groups. In one group dynamic assessment, through teaching metacognitive strategies, was administered on learners' listening skills, while the other group's listening skill was assessed formatively. After fourteen sessions a posttest of PET was administered for both groups. The evaluation of the findings showed that the dynamically assessed group outperformed the formative one.

Thermophoresis and radiative heat transfer on the unsteady boundary layer flow of a Casson fluid past an exponentially porous stretching sheet under the influence of a magnetic field in the presence of heat source/sink and chemical reaction is analysed. The governing partial differential equations of the flow are transformed into non-linear ordinary differential equations using similarity variables which are then solved numerically employing shooting technique along with Runge-Kutta iterative scheme. The graphical results reveal that the suction and magnetic field decelerate the velocity while the Casson parameter shows an opposite trend. The thermal boundary layer thickness is increased by the Casson parameter and heat source parameter. The rate of heat transfer is enhanced by thermal radiation parameter. The thermophoresis parameter along with Schmidt number is found to reduce the concentration predominantly.

The objective of the study was to investigate the impact of yogic practice and aerobic exercise on selected Physical and physiological variables among overweight school boys. To achieve this purpose, forty five overweight school boys from various schools in Tiruchirappalli district were selected at random. Their age ranged between 14 and 17. The selected subjects were randomly divided into three equal groups of 15 each, namely yogic practice group (group A), Aerobic exercise (group B) and control group (group C). The experimental group had undergone yogic practices and aerobic exercise for 12 weeks, five days a week and daily one session only in the morning, duration of session one hour, whereas the control group (group C) maintained their daily routine activities and no special training was given. Physical variable namely flexibility and physiological variable breath holding time were chosen as variables for this study. The subjects of the three groups were tested using standardized tests and procedures on selected physical and physiological variables before and after the training period. The following test items namely sit and reach and breath holding time were used to collect relevant data. The collected data were analyzed statistically through analysis of Covariance (ANCOVA) to find out the pre and post training performances. To compare the significant difference between the adjusted final means and better group. The yogic practice and aerobics exercise showed significant improvement due to 12 weeks of training on flexibility and breath holding time compared to control group.

The research was carried out on (600) broiler chick hybrids (Hibrd), in the Technical Institute of Agricultural in Damascus, between 7/1/2010 and 24/2/2010. The birds were divided into 4 experimental groups, each group containing 150 birds, each of which included 3 replicates. Birds were fed in the 1st phase on fodder without cotton seeds, while in second and third phase: Birds in the 1st group (control) were fed on plant feed without cottonseeds, with the second group birds being fed on plant feed with 5% cottonseed meal in the second phase, and 10% in the third phase. Birds in the third group were fed on plant feed with 15% cottonseed meal in the second phase, and 20% in the third phase. Results obtained showed: The addition of cottonseed meal to a plant mixture used in feeding birds in second and third phase, up to 20% of the total mixture, would not affect the cumulative mortality rate. The best profitability was in the second group, which was fed on feed with 5 and 10% cottonseed meal, with about 0.1% compare to control group.

attachment location(belonging to a place) ties to physical and social environments that support and focus on individuals tied and is accompanied by other psychological benefits. however , attachment location as a strong potential in the suburban areas, neighborhood in this way is declining and neglecting. Attachment location as a tool up to now has not been used and now, neighborhoods have been proposed for revitalizing .

Inappropriate fertilizer application usage is among the problems associated with eggplant production in Ogbomoso agro-ecological zone. Field experiment was conducted at the Teaching and Research Farm of Ladoke Akintola University of Technology, Ogbomoso to assess the effects of different fertilizers on the performance of five varieties of eggplant. The treatments consisted of five fertilizer types (No fertilizer, Inorganic fertilizer (NPK 100%), Organic fertilizer (100% compost), 50% compost + 50% NPK and 75% compost + 25% NPK) and five varieties of eggplant (Nacy, Ravenna, Nathelie, Reth and Orma). The fertilizer treatments were supplied at the equivalent rate of 60 kg N/ha. The experiment was a factorial experiment laid out in randomized complete block design. The five fertilizer types and five eggplant varieties translates to 25 treatment combinations, which was replicated three times. The agronomic and yield data collected were analyzed using the analysis of variance procedure while the treatment means were separated using the Duncan Multiple range test at 5% level of probability. It was observed that application of fertilizer improved the growth and yield attributes of eggplant when compared with where no fertilizer was applied. Combined application of 50% compost + 50% NPK and 75% compost and 25% NPK gave the highest fruit yields of 31.8 and 29.9 t/ha, respectively, which were not different significantly from each other. Ravenna variety produced the highest fruit yield (37.1t/ha). Planting of Ravenna variety with application of 50% NPK + 50% compost could be recommended for production of eggplant in the study area.

In this paper, the electronic and the structural (lattice constant) properties of ?-MgH2 are calculated, using density functional theory. The Kohn-Sham equations were solved using the full potential-linearized augmented plane wave (FP-LAPW). Generalized Gradient Approximation (GGA) and GGA+U approximations are the exchange-correlation potential used in this study. It was found that adding Hubbard-U term to GGA improved calculated structural property, energy band structure results and are in better agreement with the experimental data.

In Mobile Ad hoc Network (MANET) mobile node is responsible for route establishment using wireless link where each node may behave like both as a host and router. MANET encounters number of security threats because of its open entrusted environment, with little security arrangement, security over MANET can be enhance up to some satisfactory level because of its inherent characteristics. Among some of the prominent security threats wormhole attack is considered to be a very serious security threat over MANET. In wormhole two selfish node which is geographically very far away to each other makes tunnel between each other to hide their actual location and give the illusion that they are true neighbours and attract other nodes to make conversation through the wormhole tunnel. Many researchers focused on detecting wormhole attack and its prevention mechanism. It seems that in the previous technique there is a need to improve their results in the brink of false negative rate, routing overhead etc. The present paper has proposed the hybrid model in order to detect and prevent the wormhole attack. This approach has been work with neighbour node and hop count method.

There is a decline in the intake of fruit and vegetables and the diets have shifted toward more sugars and fats, due to urbanization. Vegetables being a rich source of soluble and insoluble fibres can be incorporated in various food products to improve the functional properties of these products. Bakery products are consumed by a wide range of population and hence bakery products, such as bread,biscuits, rusks and cookies serve as a vehicle for the incorporation of functional foods and dietary fibre. Vegetables such as broad beans, cluster beans and French beans rich in dietary fibre were selected and processed to prepare dry powder.This powder was incorporated in the bakery product rusk at 10%,20%,and 30%, level to the standard rusk recipe. The rusks were prepared separately using broad beans, cluster beans and French beans powder. The rusk biscuits were then organoleptically evaluated for the acceptability. Nutrient analysis were carried out for the standard and the fibre incorporated rusk that were selected after sensory evaluation. The glycemic index of the formulated rusk was determined to check if the fibre incorporated, reduced the glycemic load of the rusk. The study revealed that 10 percent level of incorporation of the different vegetable powders was found to be acceptable. The crude and dietary fibre content increased in the formulated rusk. The glycemic index of the beans powder incorporated rusk was less when compared with the standard rusk.
