Design and Development of Routing Protocol for WSN Simulation in GloMoSim
R. Alageswaran,O.G. Kiruthiga,T.K. Keerthika,B. Prakash
Journal of Artificial Intelligence , 2013,
Abstract: Nowadays, Wireless Sensor Networks (WSN) are emerging because of the technological developments in wireless communication and the advancements in miniaturization of sensor hardware nodes. WSN is an ad hoc network with more number of nodes densely deployed. Sensor nodes cooperatively pass the data through the network to a sink node. The research area of WSNs is growing and testing of new protocols and mechanisms developed for WSN application in real environment is infeasible as the number of nodes in WSN application is more. The use of simulation environments is an alternative to test the performance of an application prior to actual deployment. Global Mobile Information System Simulator (GloMoSim) is a open source network simulation software which simulates wired and wireless networks. GloMoSim uses the OSI reference model by using a layered approach. It supports parallel programming language called Parsec which is used for parallel discrete event simulation. It offers basic functionality to simulate wireless networks and does not support any sensor specific features and protocols for WSN simulation. Hence, without any further efforts in terms of adding protocols with the layers of GloMoSim, no WSNs can be simulated using GloMoSim. In this paper, the design, implementation of WSN routing protocol Sensor Protocol for Information via Negotiation (SPIN) and interfacing in network layer of GloMoSim is proposed. This addition makes GloMoSim suitable for WSN simulations.

Essential Trace Elements and Metal Binding Proteins in Nigerian Consumers of Alcoholic Beverages
O.G. Arinola
Pakistan Journal of Nutrition , 2008,
Abstract: Throughout the world 7% of individuals above 18 years of age are habitual consumers of alcoholic beverages, despite the fatal consequences of alcohol consumption on immune system and other organs. This study is designed to provide biochemical basis for the fatal consequences of alcohol consumption. The levels of metal binding proteins (transferrin, caeruloplasmin and alpha 2-macroglobulin) and essential trace elements (Zn, Cu, Mn, Fe and Se) were determined in male Nigerians that consume alcohol beverages compared with controls using immuno diffusion method and atomic absorption spectrophotometric method respectively. Transferrin and Zn were significantly reduced while Cu and Mn were significantly raised in alcohol consumers compared with the controls. No correlation was found between the levels of metal binding proteins and essential trace elements. Reduction of transferrin and Zn might explain susceptibility of alcohol consumers to infections and that Zn supplementation is recommended for alcohol consumers to boost their immunity.
Obliquity of the acoustic energy flow in acoustooptic alpha – BaB2O4 and Li2B4O7 crystals
Mys O.G.
Ukrainian Journal of Physical Optics , 2008,
Abstract: The obliquity effects for the acoustic energy flow are quantitatively analysed for both transverse and longitudinal acoustic waves that propagate in [011] plane of alpha-BaB2O4 and Li2B4O7 crystals. It is shown that for the slowest transverse acoustic wave the obliquity angle is equal to zero and thus the effect cannot have action on the efficiency of acoustooptic interaction.
INFLUENCE OF DOXORUBICIN ON ADHESIVE PROPERTIES OF E.COLI
O.G. Shapoval
Saratov Journal of Medical Scientific Research , 2008,
Abstract: Influence ofantineoplastic drug doxorubicin and amikacin, the aminoglycoside family on adhesive activity of Escherichia coli was studied. Antimicrobialactivity(minimum inhibitory concentration-MIC) ofboth drugs against experimental strains using serial two-fold dilution method was determined. Susceptibility of E.coli to amikacin in the presence of Sand j MIC doxorubicin was studied. After 10 passages in beef-extract broth with constant and increasing doxorubicin concentrations in the presence of Sand j MIC doxorubicin, the adhesive activity of initial and passage variants according to theirability to absorb human erythrocytes 1(0) Rh+ was determined. Itwas observed that experimental strains were susceptible to amikacin (MIC 1,5-6,2 mkg/ml) butwere resistantto doxorubicin (MIC 1000 mkg/ml). Subinhibitory concentrations of this cytostatic (S and j MIC) raised the sensitivity of experimental strains to amikacin and differently effected on adhesive activity of passage variants of E.coli.

Abstract: this article contains a report on facing violence, which constitutes a major health care problem for the population that is within the sphere of action of the uni-ba project for the barra sanitation district in rio vermelho. this issue has become fundamental as an element of the thinking involved in the development of healthcare practices as part of the process of professional training. the text debates the need for professional education to be socially contextualized, so as to provide professionals with the tools they require to face problems and the population's true health care requirements. it also comments on the strategies used to ensure a close interconnection of the world of teaching and the world of work - the reality - taking the latter as an element of fundamental importance, if active methods capable of providing a positive contribution to the development of socially committed individuals are to be adopted in the processes of teaching and learning.
Optical properties of crystals with incommensurate structure of Lifshitz’s type
O.G.Vlokh
Ukrainian Journal of Physical Optics , 2000,
Abstract: A review of optical properties of A2BX4 group crystals with incommensurate modulated structure of Lifshitz’s type a.i. crystals, which characterize nonequitranslation unit cell of high temperature and ordering - low temperature phases is done. The characteristics features of birefringence, optical activity, light absorption and the effects induced by the external influences (temperature, pressure, electric fields and mechanical stresses, X-ray radiation, as well as their gradients) are considered in this paper. It is shown that different types of interaction between defects or impurities and structural elements (pinning, viscous interaction, nucleation and annihilation of phase solitons or commensurate-incommensurate states (so-called discommensuration)) manifest themselves in the anomalies of optical phenomena in the incommensurate phases.

Abstract: An engineering geological survey using the cone penetrometer and finite element method was carried out to characterize sand-fill thick- nesses in a reclaimed area of Lagos, SW Nigeria. A previously developed finite element program was modified in order to allow for predicting the sand-fill thicknesses, and have an unders- tanding of the geomorphic shallow structures existing pre-sand-fill. The program was tested using the obtained cone penetrometer test re-sults from the Lekki-Peninsula area. The finite element predicted thicknesses show good cor-relation with the penetrometer obtained thicknesses. Six zones with thick sand-fill thick-nesses varying from 1.25 to 6.0m were identified from the isopach maps, these zones correlate with major/minor depression associated with river/stream channels and creeks. These are the main shallow geomorphic structural features present in the area pre-sand fill. The structural trends of the depressions are largely influenced by the oceanic fracture pattern.
