This research examines the influence of motivation towards academic achievement among gifted students in Saudi Arabia. The discussion in the study is base on the theoretical framework of the emotional intelligence Theory Goleman’s (1995), the Mayer and Salovey Model (1995) and achievement motivation Theory. These theories are appropriate for the study because they allow the reader to understand how academic achievement is significantly influenced by motivation among gifted students in Saudi Arabia.

The effects of annealing on the structural, morphological and optical band gap of chemically deposited cadmium selenide (CdSe) thin films have been investigated. The X-ray diffraction analysis revealed that both the as-deposited and annealed CdSe thin films had three major peaks corresponding to the cubic structure of CdSe with a preferred orientation along the (111) plane. After annealing, the intensity of the major peaks became more pronounced and a new low intensity peak was observed. There was also a slight shift in peak positions towards smaller 2? angles. The average crystallite size increased after annealing whereas the microstrain and dislocation density decreased. The SEM micrographs of the annealed thin film showed a slight improvement in crystallinity and uniformly distributed all over the surface of the substrate without voids. The optical energy band gap of the thin films decreased from 1.86 eV to 1.74 eV after annealing.

Wireless Sensor networks are dense wireless networks of small, inexpensive, low-power, distributed autonomous sensors which accumulate and propagate environmental data to facilitate monitoring and controlling of physical environments from remote locations with better accuracy. With the advent of new technology and low production costs, wireless sensor networks (WSN) prove to be useful in myriad of diversified applications, although its original development was motivated by military applications, such as battlefield surveillance. This paper describes the software architecture of an intelligent autonomous gateway, designed to provide the necessary middleware between locally deployed sensor networks based on mobile node and a remote location. The gateway provides hierarchical networking, auto management of the mobile wsn (MWSN), alarm notification and SMS/Internet access capabilities with user authentication. The main concern of QoS-based quadratic assignment technique is to increase reliability of network along with lifetime of the network. Several factors such as energy lifetime, throughput, end to end delay, packet delivery ratio and network security have been taken into consideration. Simulation results shows that the protocol offers a better performance in terms of network lifetime and energy consumption.

Energy as electromagnetic waves has primary and secondary effects. Certain shapes have affect the secondary effect either positively or negatively. BioGeometry is dealing with shapes which affect positively on energy. BioGeometry has principles of designs which used during design shapes. Fashion designs also have elements and principles which used during clothing designs. The human body has an open energy system that is in instant exchange on the subtle energy level just as it is in other levels. The first boundary between the body's energy system and environment is on the level of what we aware, as a bounday our clothes affect the energy exchange in both directions. The object of this research is to study how this boundary can affect the quality of energy exchange in order to bring harmony within the human subtle energy system and have positive effect on the vitality, emotional and mental levels. In this research fashion design sketches were drawn. Their energy determined qualitatively, one sketch selected and modified by BioGeometry design principles and then , ten creative fashion designs applied which principles and elements of both BioGeometry and fashion design are analyized. Further studies needed to complete full observation.

In the resent world, various study based on overall development of women such as their social status, social benefits, their constitutional rights and their education provided by modern scholar proved that, their status in modern society is totally different from traditional society. Establishment of democratic society like in India pays especial attention for women development. While the presence of gender discrimination in traditional society influence the mentality of the today’s people, due to this in many rural areas of India women are still behind the bar. The structural behaviour of ancient society proved that women were always dominated by the male members. They are mainly concentrating on domestic work only. In this study researcher try to examine the participation of women in vegetable market as a seller along with their problems during market time, their socio-economic condition and the factors which influence their participation on vegetable market as seller. It is true that women are participating in various sectors and their number is also increasing but at the same time they are not free to exercise their power. They work under pressure of various factors such as unhealthy working environment, social security, public pressure and family pressure. Thus, central and the state Government gives high priority for the social empowerment of women in their policies.

The Ab-initio and charge density analysis of Au and thiol substituted Dicyclopentyl-Cyclohexan (DCC) molecular nanowire, was carried out using high level Density Functional Theory (DFT) with the help of LANL2DZ basis set coupled with the Bader’s theory of atoms in molecules . All the studies were carried out in the presence of an applied electric field which is gradually increasing from 0.05–0.26VÅ?1. The effect of the applied electric field on the geometrical and the topological analysis of the molecular wire is thoroughly made and studies were made to charcterise the bonds, especially the terminal bonds, which shows ionic nature. The variation in the dipole moment as a consequence of the polarization caused by the applied EF is thoroughly studied. HOMO-LUMO analysis was carried out to determine the way the molecule interacts with other species which may initiates the conductivity. The I–V characteristics of the molecule have been studied for various applied fields for finding the conducting nature of the molecule-electrode-molecule system. The molecular electrostatic potential surface was plotted over the geometry of the molecule to elucidate the reactivity of the molecule.

In this paper the numerical study of unsteady flow of a viscous incompressible fluid past an exponentially accelerated infinite vertical plate with radiation, viscous dissipation, chemical reaction and variable heat and mass diffusion have been analyzed in the porous medium. To obtain the non-similar momentum, energy, and concentration equations usual non-dimensional variables have been used. The dimensionless governing equations are solved numerically by explicit finite difference method. Here velocity, temperature and concentration fields are described graphically for the different physical parameters. Skin friction and Nusselt number profiles have been also described graphically here.

In the title compound, C22H19ClN4, the pyrrole and pyrimidine rings form a dihetrocyclic fused pyrrolo-pyrimidine ring system which is almost co-planar; dihedral angle between two ring planes is 6.2º, to which five membered pyrrolidine ring is substituted, which is puckered to attain half chair conformation. Two other rings chloro-phenyl and phenyl are substituted at the 7 and 9 positions respectively in the fused ring system. Chloro-phenyl ring also shares the plane of fused ring system. (Dihedral angle between two ring system is 12.4º.) Crystal packing is stabilized due to ?-? interaction observed between pyrrole and chloro-phenyl ring of its symmetry related molecules (centroid-centroid distance: 3.8641 Å). Intramolecular C-H…N hydrogen bond is also observed in the molecular structure.

In present study shows the seasonal biochemical variations in different tissues of M. meretrix. In summer and monsoon seasons the glycogen content was decreased as compared with winter season. Glycogen level fell during spawning and later recovered with gametogenesis. Protein content in different tissues in winter and monsoon season was high as compared with summer season. Protein contents values observed high during the period of spawning. In summer and monsoon seasons, the lipid content was increased but decreased in winter season. The lipid content level was high at the period of spawning.

The granites of part of Nalgonda district is a metaluminous, high K-calc alkaline,I-type granite emplaced into the gneissic rock of the Peninsular Gneissic Complex of the Eastern Dharwar Craton. The thin section study clearly evidence that the granite is of pure magmatic origin. The deformation signatures were also noticed of brittle-ductile shear both in field and thin section studies in laboratory. Geochemically, the granite is rich in K2O+Na2O, suggesting it is an alkali granite with calc-alkaline magma. On a Yb vs Ta discrimination plot, the granites are falling mostly in the volcanic arc granite field. The REE pattern shows strong Eu negative anomaly, suggesting early separation of plagioclase. The enhance level of LL element relative to HFS element point to the subduction zone enrichment and/or crustal comtamination of the source region.
