Authors: Mykola Krupa, Andrii Korostil

International Journal of Physics, 2013 1 (2), pp 28-40. 10.12691/ijp-1-2-2

We have studied the mechanisms of a pulsed laser impact on the magnetization conFigureuration in ferrimagnetic multilayered magnetic nanostructures, specifically, tunneling magnetic junctions. The mechanism of such the laser-induced impact is a complex process of laser-induced thermal demagnetization of magnetic sublattices with subsequent biasing by internal magnetic fields of different nature. Depending on an intensity of laser pulses it can be effective... [FIND OUT MORE]

American Journal of Mechanical Engineering, 2013 1 (3), pp 66-72. 10.12691/ajme-1-3-2

This paper presents analytical simulation of drag braking during deployment of a solar array system of a small satellite within the space environment, and helps the designer to detect problems during ground testing. The deployment mechanism (DM) is modeled by using Mechanical Desktop (MDT) software and analyzed by using Finite Element Analysis Package (ANSYS 11). Design and Stress analysis of DM is performed at the most critical points during its functioni... [FIND OUT MORE]

Journal of Materials Physics and Chemistry, 2013 1 (1), pp 4-8. 10.12691/jmpc-1-1-2

Single crystals of L-Proline Succinate (LPS) were grown by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to monoclinic crystal system. The optical transmission study reveals the transparency of the crystal in the entire visible region and the cut off wave length has been found to be 210nm. The optical band gap is found to be 5.90eV. The transmittance of L-Proline succinate crystal has been used to ca... [FIND OUT MORE]

Semi-Empirical Evaluation of the Probability of Structural Rearrangements in Nitrone Spin Traps

Authors: F. N. Dultsev, G. G. Dultseva

Chemical Engineering and Science, 2013 1 (2), pp 17-21. 10.12691/ces-1-2-1

Structural rearrangements induced by the action of oxidizers in nitrone spin traps are investigated by means of the semi-empirical calculation of energy changes that accompany the processes assumed on the basis of experimental observations. The mechanisms of cyclization of acyclic nitrones and cycle opening in cyclic dinitrones are assumed on the basis of calculation results. It is shown that water as a solvent plays an important part in these structural r... [FIND OUT MORE]

New Era Sport Sponsorship in Turkey

Authors: Ridvan EKMEKCI

Journal of Business and Management Sciences, 2013 1 (1), pp 10-13. 10.12691/jbms-1-1-3

The aim of this paper was to define and focus on Sport Sponsorship in Turkey according to financial issues. Sport sponsorship was very weak in Turkish sport area before 2004. By the time, The Turkish Government has decided to legislate a special law for supporting “SPORT” and they have regulated some of the financial laws based on 1986 General Directorate of Youth and Sport (GDYS) Law.The new law has started a very efficient age for Turkish sport. On the o... [FIND OUT MORE]

Fleet & Convoy Management Using VANET

Journal of Computer Networks, 2013 1 (1), pp 1-9. 10.12691/jcn-1-1-1

In this paper, a Fleet/Convoy Management System, based on the GeoNet architecture for Vehicular Ad-hoc Network (VANET) is discussed and implemented. Fleet or convoy management is a special case of VANET, where nodes require communication to same type of other nodes as well as to backend server. Critical applications have been identified which are required for improving the load management and overall efficiency of such networks. The design is based on four... [FIND OUT MORE]

Using Geographic Information System and Analytical Hierarchy Process in Landslide Hazard Zonation

Applied Ecology and Environmental Sciences, 2013 1 (2), pp 14-22. 10.12691/aees-1-2-1

Nepal frequently suffers from various types of water induced disasters like soil erosion, landslide, debris flow, flood etc. To mitigate the problem related to Landslides & Debris flow, Landslide Hazard zonation is important to quick and safe mitigation measures and make strategic planning for the future by identifying the most vulnerable areas and channelizing most of the protective measures and techniques to a more focused area. This study was carried ou... [FIND OUT MORE]

Investigation on Early Development, the Feeding Ability and Larval Survival under Starvation in Common Meagre, Argyrosomus regius (Asso 1801)

Authors: Aikaterini Klimogianni, Maria Pagoulatou, Maria Trageli, George N. Hotos

Journal of Aquatic Science, 2013 1 (2), pp 14-22. 10.12691/jas-1-1-1

The development of Argyrosomus regius early development stages (embryonic, yolk sac and newly larval) was studied, with emphasis on yolk and lipid absorption. The effect of a progressively delayed initial feeding on the feeding ability and survival of this species was also examined. The number of days from hatching after which the feeding rate dropped to half the initial highest feeding rate or the point of no return (PNR) was determined. In... [FIND OUT MORE]

Biodegradation of the Synthetic Pyrethroid, Fenvalerate by Pseudomonas viridiflava

American Journal of Microbiological Research, 2013 1 (2), pp 32-38. 10.12691/ajmr-1-2-4

A current environmental concern is the contamination of aquatic ecosystems due to pesticide discharges from manufacturing plant, agricultural runoff, leaching, accidental spills and other sources. The degradation of synthetic pyrethroids in the environment is an important index in the evaluation of ecological risk of pesticides. Microorganisms play a significant role in detoxifying pesticides in the environment. There are few reports on the degradation of... [FIND OUT MORE]

Determining the Effectiveness of Personalized Versus Prescribed Self-Talk on Athletic Performance for Elite and Novice Athletes

Authors: Jane E. Magnusson, Carl A. van Roon

American Journal of Applied Psychology,2013 1 (1), pp 1-6. 10.12691/ajap-1-1-1

An athlete’s performance can be influenced in positive and negative ways by what and how they think (i.e. their self-talk). While there is evidence indicating that self-talk can influence performance it is not clear if the level an athlete has achieved in their sport influences the effect that self-talk has on their performance and/or what type of self-talk is of greatest benefit to them. The present study investigated if personalising self-talk makes it m... [FIND OUT MORE]

Bar-Coded Enterobacteria: An Undergraduate Microbial Ecology Laboratory Module

American Journal of Educational Research,2013 1 (1), pp 1-6. 10.12691/education-1-1-6

Microbial community ecology is an area of rapid growth centered within the larger discipline of microbiology. Newly developed research methods using molecular strategies have transformed this area into an accessible research topic. Despite such advances, transmission of this topic into pedagogical form has lagged behind. To improve this situation, an undergraduate research team created an artificial microbial community for class room use. They used color-c... [FIND OUT MORE]
