In this article, we studied the effects of variable viscosity and thermal conductivity on an unsteady two-dimensional laminar flow of a viscous incompressible electrically conducting fluid past a semi-infinite vertical plate taking into account the mass transfer. The fluid viscosity is assumed to vary as a linear function of temperature. The governing equations for the flow are transformed into a system of non-linear ordinary differential equations are solved by a closed analytical form. The effects of the various parameters on the velocity, temperature, concentration and skin-friction profiles are presented graphically.

Research on food science and technology is necessary to fuel food industries, it will leads to generation of employment, growth of agriculture, increase in export and improvement of economy. During last five years, Indian food processing sector show 8.4% growth but country is dependent on import of technologies. India needs domestic technologies for agro-based rural industries, value addition, food preservation and processing, nutrition enhancement and management of food wastage (Economic Survey 2013-2014).

Using of tuned mass damper is a common way for reducing responses of structures as a result of wind and earthquake. This damper is consisted of concentrated mass which is connected to the point of structure by a damper and spring. In this paper frame of last floor is used for placing tuned mass damper. For this reason, four models of 4, 8, 12, 20 floor buildings with moment resistance frame are studied under effect of earthquakes of near field Leandros, Northrdig, Kube and Tabas faults. So, mass damper which is suggested on the base of improved values in scientific resources is calculated. On the base of these results, it is possible to found appropriate behavior of tuned mass damper in 12 and 20 buildings.

Purpose of this paper is to review the role and impact of top management commitment and leadership on total quality management (TQM) in service organizations in Malaysia, and to come out with a conceptual framework model. A total of 15 related studies selected from well known electronic academic resources and databases (e.g. Emeraldinsight, Elsevier Sciencedirect and Scopus) and deeply reviewed. A proposed conceptual framework developed according to the finding and theoretical dimensions of those papers. Outcomes of this paper will: enrich the literature in the field; will underline trends of the research in role of top management leadership and commitment in TQM practices; and will provide fresh insights to academic researchers interested in the field of TQM as well as to organizations managers.

Hexane, diethyl ether, dichloromethane and ethyl acetate extracts of twenty five plant species, including fourteen varieties of leaves, five varieties of whole plants, two varieties of barks and one variety of flower, fruit, seed and root were tested for ovicidal activity against Culex quinquefasciatus at 1000 ppm. During preliminary screening, significant ovicidal activity was observed in all four solvent extracts of Cleistanthus collinus, Hydrocotyle javanica, Leucas aspera, Murraya koeingii, Sphaeranthus indicus and Zanthophyllus limonella.  Solvent crude extracts of plants showing maximum ovicidal activity were selected and treated at 500 ppm. The percentage of egg hatchability significantly reduced in different solvent extracts of above mentioned plants and eggs treated with different plant extracts varied from 26.59 per cent  in diethyl ether extract of Murraya koeingii  to 82.61 per cent in hexane extract of Leucas aspera.

In this paper we apply Double A booth transform to solve the general linear telegraph equation. The applicability of this new transform is demonstrated using some functions.

Motivation plays an indispensable role in learning. Though motivation has got a lot of attention in literature of language learning, demotivation has not got much attention in general and particularly in Iranian EFL context. As Dörnyei (2001: p. 5) postulates "Demotivation is a salient phenomenon in L2 learning" and "much further research is needed to do this important motivational factor justice". The aim of the present study is to find out what the main demotivating factors in speaking skills among gifted students at SAMPAD schools are. In order to achieve this goal, 571 students who are secondary students in SAMPAD schools in Tehran were selected. The sampling was convenient sampling, and both male and female students participated in this study. A questioner which was validated and reliable was distributed among participants, and 68 students were interviewed. The findings of both quantitative and qualitative data reveal that five demotivating factors hindering learners in speaking classes are, teacher, material and content, facilities, attitude and teaching learning context. The findings can be applied for teacher development courses in which mentors can shed light on the importance of motivational factors in EFL classes. Key Words: motivation, demotivation, speaking skills, exceptionally talented students

The emerging Cognitive Technology promises to improve the network spectrum-utilization efficiency by allowing cognitive secondary users (SUs) to intelligently sense and opportunistically access those spectrum holes temporarily unused by license-holding primary users (PUs). Cognitive radios hold tremendous promise for increasing spectral efficiency in wireless systems. In this paper, we propose a cooperative spectrum sharing scheme between cellular network downlink and mobile ad-hoc network based on the analysis using stochastic geometry theory. The licensed spectrum belongs to the cellular network and the strong interference at cell-edge becomes a bottleneck to guarantee the quality of service requirement. In this case, the secondary ad-hoc users can assist the transmission between the base station and cell-edge mobile users in exchange for spectrum usage. Through maximizing the transmission capacity of secondary system under the constraint of throughput improvement of primary system, an optimal spectrum allocation can be obtained. Numerical and simulation results are provided to validate the analysis and verify the efficiency of the proposed scheme.

In this paper we have reported the Stokes Parameters of excited Magnesium atom using non-relativistic (DW) and relativistic distorted wave approximation theories (RDW) at incident electron energies 15 and 45 eV. Good agreement has been found on comparison of both DW and RDW methods with each other and the importance of relativistic effect is also explored.

Vehicular Ad Hoc Networks (VANET) is a subclass of Mobile ad hoc networks which provides a distinguished approach for Intelligent Transport System (ITS). The survey of routing protocols in VANET is important and necessary for smart ITS. This paper discusses the advantages / disadvantages and the applications of various routing protocols for vehicular ad hoc networks. It explores the motivation behind the designed, and traces the evolution of these routing protocols. This paper discusses the main 5 types of protocols for VANET Topology Based, Positioned Based, Geo Cast, Broad Cast, Cluster Based Protocols.
