The unsteady gravity-driven convective flow and heat transfer of optically thick nanofluid past an oscillating, vertical plate is considered. The flow is confined to y > 0 where y is the coordinate measure in the normal direction to the plate. The fluid is assumed to be electrically conducting with an uniform magnetic field applied in a direction perpendicular to the plate. The resulting equation is solved by making use of Laplace transform method. Velocity profile and temperature profile are drawn for different values of radiation parameter and magnetic parameter.

The synthesis and Biological activity of 2,4,5-trimethoxy benzaldehyde Thiosemicarbazone ligands have been reported. The Infrared and Elemental analysis have been assigned. The data agree quite well with the proposed structures. The group sensitive fundamentals are compared with those of similar molecules already reported in the literature. Ligand were screened for antimicrobial activities by the disc diffusion technique using DMSO as solvent. These Schiff base has been studied for their anti-bacterial ,anti-fungal, and anti oxidant activity. The antifungal activity of the said ligand has been screened against Aspergillus flavus, Asperjillus niger and Antibacterial activity tested against Vibrio harveyi , VibrioVulnificus, Escherichia Coli, Bacillus pumilus.The anti oxidant activity againt catalase assay.

This paper attempts to study the determining factors of Wadiah Saving Deposits in Malaysia. It intends to examine the relationship between Gross Domestic Product (GDP), Inflation Rate (INF), and Rate of Return (ROR) and Wadiah Savings Deposits in Malaysia. Analysis was done by using the Statistical Package for Social Science (SPSS). Some of the techniques used to measure the factors were Pearson Correlation, coefficient of determination (R2), ANOVAs, Multiple regression analysis, and T-statistics. Using the data from Monthly Statistical Bulletin, Bank Negara Malaysia from 2003 until 2010, and this study found that Rate of Return (ROR) influenced the changes of Wadiah Saving Deposits in Malaysia. By using T-statistics, the results showed that only one independent variables namely Rate of Return (ROR) had significant influence with Wadiah Saving Deposits while Gross Domestic Product (GDP) and Inflation Rate (INF) had no significant influence with Wadiah Saving Deposits.

In this study the effect of land size on energy use of strawberry production in Iran was investigated. The data were collected from 110 farmers in 13 villages growing strawberry in Kurdistan province of Iran. The land size was categorized into 4 groups. Total input energy for the first group, second group, third group, and last group was 60556.6 MJ ha^-1, 49313.5 MJ ha^-1, 49823.7 MJ ha^-1, and 37234.1 MJ ha^-1, respectively. The difference between mean values of first group and last group was significant at the 5% significance level. The difference between mean values of other groups was not significant at the 5% significance level.

The optimal expansion of rocket nozzle has been occasionally attained due to the variation of altitude as the ambient pressure of these altitudes decreases with increase in altitude. Optimal gas expansion occurs only at a particular altitude when the nozzle’s exit pressure (Pe) is equal to the ambient pressure (Pa) of that altitude. There are special altitude adoptable nozzles such as aerospike nozzles, expansion-deflection nozzles and others designed for optimal gas expansion as the altitude increases. However, these nozzles adds weight to the rocket and are expensive for production. This study has been conducted with an experimental Rocket nozzle designed and developed by NSS (Nair Service Society) College of Engineering Palakkad-Kerala, India using computational fluid dynamics to determine the effect of varying the combustion chamber pressure to balance the nozzle exit pressure to the ambient pressure as the rocket ascends in altitudes. From the results obtained, it was observed that there is a conformance of up to twenty three (23) kilometers using the nozzle understudy for which further variation in combustion chamber pressure developed subsonic flows and shock waves in the divergent section of the nozzle. Further analysis showed that the total mass of propellant consumed was 36% per stage engine less than most conventional method of launching rockets engines to orbits. This method of variation of chamber pressure to balance the nozzle exit pressure with the ambient pressure provides potentials for reduction in energy consumption of a rocket.

Naturalness as a main inseparable feature of literary texts may be exposed to some mistranslations or misunderstandings from the part of the translators during the act of translation. A major issue is probably the level of the difficulty of the source text. There is a sever lack of research on the impact of text difficulty on translation naturalness at the micro level with regard to the formal and dynamic equivalents. Accordingly, the current study as an initial attempt in Iran aimed at examining the common elements of word and sentence pertinent to text difficulty and translation naturalness. To this end, the researcher aimed at finding out the relationship between formal and dynamic equivalents for simple and difficult texts. A pool of 86 students participated in the study to serve as the source of data. Having assessed the students’ performances on the tests based on Nida’s criteria, the researcher found a moderate correlation for formal and dynamic equivalents with regard to the simple texts and a strong correlation for formal and dynamic equivalents with regard to the difficult texts. Finally, some implications for translator teachers and syllabus designers were recommended.

A new integral transform similar to Laplace and Sumudu transforms is introduced, to explain the use of Tarig transform in differential equations, an example of first and second order linear differential equations are presented. In this work we show that the applicability of this interesting new transform its very efficiency to solving differential equations with constant coefficients.

Traumatic shoulder dislocation in Child is a very rare injury. The treatment and the recurrence rate are differents then adult. We report a case of shoulder dislocation in a 9 years old judoka.

The primary responsibility of the principal in a school set up is to facilitate effective teaching and learning with the overall mission of enhancing students’ achievement. Instructional leadership provided by the principal has been identified as a contributing factor to higher student achievement. This study was guided by the following objective: to establish the principals’ role in supervision of curriculum and its effect on academic performance. This study was anchored on Hackman and Walton’s Functional Leadership Theory (1986) which addresses how specific leader behaviors contribute to organizational and leadership effectiveness. The study employed both qualitative and quantitative methodology. The researchers sampled 20 (67 %) out of the total thirty schools in the region. Census sampling technique was used to select one extra county boys’ school, one extra county girls’ school, one county girls’ boarding school, one sub county girls’ day school and purposive sampling technique was used to pick sixteen other secondary schools from the categories of county mixed day/boarding and sub-county mixed day schools. The findings indicated that Most principals believed that the instructional practices of the principals impacted positively on academic performance of their schools. Most of them also facilitated acquisition of instructional materials, and helped in organizing the teaching timetable and school routine, which qualified them as instructional leaders.

The inefficaciousness and ethical deficiency of the current “Islamic” financial industry is well known. Taking a diachronic approach whilst resorting to scriptural reasoning, historical evidence and inductive rationale, the author suggests two prerequisites for Islamic financing. The paper is concluded with five scenarios that are in the author’s view, sine qua nons as far as Islamic financing is concerned.
