http://ijaems.com/ Open Access international Journal to publish research paper en-us March 2018 Heat transfer is one of a number of indispensable tools in studying of ICEs, due to its influence on decisive parameters of operation like temperature and pressure inside the cylinder. It is safe to say that modeling of the engine heat transfer is among the most complex problems for engineers. Application of numerical methods to predict the heat transfer in a cylinder of reciprocating ICEs is a process of high importance, which was recognized from the earliest stages of their development. This is done to examine performance optimization and design improvement in order to meet nowadays demands exhibited on the engines. This present study focuses on a 3-D transient state temperature distribution analysis on a gasoline engine model via formulated of models, simulating using FEM in-built in the COMSOL Multiphysics software 4.3a to determine the temperature distribution and gradient of the engine cylinder head model. The number of degrees of freedom solved for were 32685 in 383 s (12 minutes, 20 seconds) in the mesh optimization. From the result obtained it was discovered that the heat transfer in the combustion chamber of the ICE varies with time. Thus, it took the engine 10 minutes to complete a cycle vis-a-vis transfer of heat after combustion and that the heat transfer starts after 30 seconds of combustion. In addition, the temperature of the cylinder dropped from 1273.2 K to 301 K over a period of 10 minute. http://ijaems.com/detail/numerical-simulation-and-modeling-of-unsa91060-for-heat-transfer-in-four-stroke-ice-cylinder-head/ Olaiya Kamorudeen Adesina, Alabi Ismaila Olanrewaju, Falana Kafayat Abolanle http://ijaems.com/upload_images/issue_files/1 IJAEMS-FEB-2018-4-Numerical Simulation and Modeling.pdf A study was conducted to find out the antioxidant activity of medicinal rice (Oryza sativa L.) cv. Njavara. Two eco types of Njavara rice Njavara black (NB) and Njavara yellow (NY) were procured from RRS, Moncompu and one eco type of Hraswa was obtained from ARS, Mannuthy. Hraswa was treated as the control. Diphenyl picryl hydrazyl (DPPH) radical scavenging activity, hydroxyl radical scavenging activity, superoxide anion radical scavenging activity, reducing power assay, total antioxidant activity, total phenols, zinc and selenium (Se) were estimated. The results of the antioxidant properties revealed that for DPPH scavenging activity and hydroxyl radical activity NY had highest antioxidant activity. For superoxide radical scavenging activity, NB had the highest activity. Present investigation showed that as the concentration increased, the reducing power of all the rice varieties increased and the highest reducing power was shown by NB. NY had shown the highest total antioxidant activity. Present study revealed that among the three rice varieties NB had the highest total phenol content. Zn content was slightly higher in NY than NB. The present study revealed that control variety Hraswa had the highest Se content. http://ijaems.com/detail/antioxidant-activity-of-indian-medicinal-rice-oryza-sativa-l-cv-njavara/ Reshmi.

For the purpose of this paper, the researchers would like to delve into the question of gender and analyze it viz-a-viz the current condition of leadership in India. The paper begins by asking important questions as to whether gender matters in becoming a leader in India. The conceptual category of gender is explored through a thorough analysis of how is leadership conceptualized as well as the ways in which rituals, beliefs, and cultural practices essentialise gender roles. The paper aims to chart out the existing gender gap in the corporate sector and offer negotiations to deal with that. Cases of Indian woman leaders are taken up as methodological tools to unpack the gendered dynamics in leadership. The paper attempts to flag the lacunae created in the Indian leadership realm due to sometimes subtle and sometimes not so subtle functioning of patriarchy by unraveling the nuances of working in the corporate sector. Woman empowerment has become a generous subject of concern for our society. Although it is prominently related to social aspect inprevailing scenario it has gained importance in terms of technological and political factors also. http://ijaems.com/detail/it-s-time-for-a-new-discussion-on-woman-in-india-under-the-perspective-of-gender-leadership-issues/ Palak Jain, Gazala Yakoob, Dr. Rakesh Gupta http://ijaems.com/upload_images/issue_files/4 IJAEMS-FEB-2018-18-It’s Time for a New Discussion.pdf Nowadays, e-commerce has been dominating trade business.

One of the methods for improving the performance under quasi-static loading is to vary the cross-sectional shapes. In the real case, structures are seldom subjected to pure axial or pure bending rather they are subjected to a combination of two load cases i.e. oblique loading. In this paper, the circular cross-section was combined with four different polygonal cross-sections namely tetragon, hexagon, octagon and decagon and a total of 13 geometries were obtained. The buckling behavior of each tube was investigated numerically at various angles of inclination. Each tube was modeled in SOLIDWORKS and then was analyzed in ANSYS. Linear buckling code was used for finding the critical load at various angles ranging from 0° to 14°. The overall result was then compared and it was found that the proposed geometry can be a good alternative over conventional circular tubes in terms of load-bearing capacity at angular load. http://ijaems.com/detail/behavior-of-thin-walled-tubes-with-combined-cross-sectional-geometries-under-oblique-loading/ Afaque Umer, Bakhtawar Hasan Khan, Belal Ahamad, Hassan Ahmad, Mohd.

Questionnaires were used to collect quantitative data in two private universities namely Iringa University and Ruaha Catholic University. Stratified sampling technique was utilized to ensure sample representativeness among two universities where simple random sampling was used to draw a sample from each stratum during the survey. Finding Using Structural Equation Modeling indicated that performance expectancy (source code production and software localization) and social factor (Vendor, internet services provider and lecturer) have a significant influence toward behavioral intention while effort expectancy was found to be insignificant. In addition the behavioral intention was found to be significant toward student’s actual usage of open source software in Universities. This study recommended that for students to develop behavioral intention toward OSS actual usage, internet service provider have to increase the level of internet services that can assist the university communities to access and download open source software. In addition, to increase actual use, open source software vendors and lecturer or experts have to make sure that their software source code is free for distribution and localization, this will increase self-motivation and interest of the students toward actual usage of open source software. http://ijaems.com/detail/an-analysis-of-behavioral-intention-toward-actual-usage-of-open-source-software-among-students-in-private-high-learning-institution-in-tanzania/ Alberto Gabriel Ndekwa, Edephonce Ngemera Nfuka, Kalugendo Elizeus John http://ijaems.com/upload_images/issue_files/7 IJAEMS-FEB-2018-15-An Analysis of Behavioral Intention.pdf In this work, statistical modeling and optimization of biodiesel production from Azadirachta Indica(neem) using co-solvent technique via a two-step transesterification process was carried out. Neem oil was extracted from neem seeds and properties such as moisture content, specific gravity, acid value, saponification value and iodine value were determined. The experimental design used was Central Composite Design. The range of factor levels used for the Central Composite Design were reaction temperature (30°C to 46°C), catalyst amount (0.8% to 1.2%, w/w), reaction time (20 to 40min) and methanol-to-oil molar ratio (5:1 to 9:1). The co-solvents used were methanol and diethyl ether. The co-solvent-to-methanol volume ratio for all the experimental runs was kept constant at 1:1. Also the biodiesel produced was characterized for some important properties including acid value, specific gravity, saponification value, iodine value, cetane number, ester value, kinematic viscosity, flash point, pour point and cloud point. Optimized biodiesel yield of 84.77% was obtained for reaction time of 35 min, catalyst amount of 1.10g, reaction temperature of 34°C, and oil-to-methanol molar ratio of 6:1. The cetane number (51.733), specific gravity (0.8881g/cm3), flash point (134oC) and kinematic viscosity (5.86mm2/s) of the produced biodiesel met the ASTM specifications. The results of characterization of the biodiesel revealed that biodiesel can be produced at lower reaction conditions and with comparable fuel property with biodiesel produced using conventional methods. http://ijaems.com/detail/statistical-modeling-and-optimization-of-biodiesel-production-from-azadirachta-indica-neem-using-co-solvent-technique/ Nnodim C.

We have studied the effects of various doping percentage of (TiO2) on (Fe2O3) optical and electrical properties. The optical parameters of the prepared films as absorbance, absorption coefficient, optical energy gap and refractive index have been calculated for all prepared films. D.C conductivity and Hall effect for all films are measured. The results showed that absorbance of prepared films decreases with increasing percentage of (TiO2) this lead to increase the energy gap and conductivity decreased with increasing of percentage of (TiO2) as well as the results showed throughout the study that all films have tow activation energy, its value increase with increasing of percentage of (TiO2). Hall effect measurement showed all films have n-type conductivity. http://ijaems.com/detail/optical-and-electrical-properties-of-tio2-doped-fe2o3-thin-film-prepared-by-spray-paralysis-technique/ Asia Hussein Kahdim, Nahida B.

Njavara. Njavara rice for the study was procured from Rice Research Station, Moncompu. For assessing the efficacy of Njavara on the blood sugar levels, a feeding trial for 3 months was conducted among five subjects who were diabetic and willing to participate but not on medication. Blood sugar levels were monitored during 0, 45 and 90th day of supplementation. The results revealed that for all subjects’ blood sugar levels decreased after supplementation study. Diphenyl picryl hydrazyl (DPPH) radical scavenging activity, hydroxyl radical scavenging activity, superoxide anion radical scavenging activity and Vitamin E level were also ascertained. The findings revealed that after the supplementation of Njavara, the DPPH scavenging activity, hydroxyl radical activity, superoxide anion-radical scavenging activity and vitamin E level of the blood samples of all the five subjects under study have increased. http://ijaems.com/detail/medicinal-properties-of-njavara-rice-oryza-sativa-l-cv/ Reshmi.R, Nandini P.V http://ijaems.com/upload_images/issue_files/10 IJAEMS-MAR-2018-9-Medicinal Properties of Njavara.pdf The geographical position, political stability and market opportunities offered by Morocco have attracted the interest of several multinational companies either through acquiring local companies or setting up new subsidiaries. As a way of securing adequate competencies in new markets, these companies resort to the expatriation of their executives. However, this strategy does not come without direct consequences or hidden costs. In this context, researchers and managers are urged to explore the reasons for the expatriation of executives. Hence, the aim of this research is to test the model of Roger and Mérignac (2005), while focusing on the family profile and the impact of the family on the adaptation of the expatriate in Morocco. Within this research, a number of hypotheses were formulated and to verify them we will adopt a quantitative approach. The results revealed a slight difference in the adaptation according to the family profile. The most suitable expatriates are those who are accompanied by their families. Nevertheless, these results confirm the general tendency of the researchers on this problematic. A study with a larger sample would show better results. http://ijaems.com/detail/the-three-facets-of-the-adaptation-of-expatriates-to-morocco-under-the-effect-of-the-family-profile/ Lamiaa Laouami, Mohammed Faridi http://ijaems.com/upload_images/issue_files/11 IJAEMS-MAR-2018-8-The three facets of the adaptation.pdf The principle point of this task is to build up an Intelligent Monitoring System used to screen the Road Surface Condition using Fog Computing that increases the road safety. Multiple solutions have been proposed which make use of mobile sensing, more specifically contemporary applications and architectures that are used in both crowd sensing and vehicle based sensing. Nonetheless, these initiatives have not been without challenges that range from mobility support, location awareness, low latency as well as geo-distribution. As a result, a new term has been coined for this novel paradigm, called, fog computing. http://ijaems.com/detail/automated-sensing-system-for-monitoring-road-surface-condition-using-fog-computing/ Nafras Ameer B.A, Pradeep Kumar J, Kumaran V, Dinesh P, Mr. M.
