Authors: Simardeep Kaur, Dr. Harsh Sadawarti, Mohit Kumar

Abstract: Proteins are the most important macromolecules of life. The knowledge of protein function is an important link for the development of drugs, crop development and synthetic bio-chemicals like bio fuels. Different techniques are applied for the protein function prediction. These techniques are based on protein sequence, protein structure, genomic data, protein interaction networks etc. In this paper we will use docking for the prediction of protein function .The docking technique makes the database search faster .By applying docking for the protein function prediction we can easily find the complementary proteins for the target proteins during the drug discovery process which makes this process fast. . Docking technique also helps in classification of enzymes and their mechanisms .By applying docking the virtual screening of the compounds could be done.

Title: Influence of succinic acid on the corrosion inhibition of Sodium metavanadate in chloride medium

Authors: V. Sribharathy, Susai Rajendran

Abstract: The inhibition efficiency (SMV) – succinic acid system is controlling corrosion of carbon steel in an aqueous solution containing 60 ppm of Cl- has been evaluated by weight loss method.250 ppm of SMV has 56% of IE. Addition of succinic acid to SMV improves the inhibition efficiency of the system. Formulation consisting of 250 ppm of SMV and 250 ppm of succinic acid has 97% IE. Synergistic effects exist between SMV and succinic acid, if the synergism parameters are greater than 1. Mechanistic aspects of corrosion inhibition have been studied by electro chemical studies like polarization and electro chemical impedance spectroscopy. FTIR spectra reveals that the protective film consists of Fe2+ – SMV complex and Fe2+ -succinic acid complex, the protective film has been analyzed by fluorescence spectra, SEM and AFM .

Keywords: Carbon steel, corrosion inhibition, fluroscence, synergism parameter, SEM.

Title: Experimental Studies on the Effect of Ceramic fine aggregate on the Strength properties of Concrete

Authors: Siddesha H

Abstract— Increased construction activity and continuous dependence on conventional materials of concrete marking are leading to scarcity of the construction material and increased construction cost. In this study an attempt has been made to find the suitability of ceramic fine aggregate as a possible substitute for conventional fine aggregate in concrete. Experiments were carried out to determine the compressive, split tensile and flexural strength of ceramic fine aggregate and comparison is made with conventional concrete. Test results indicate that, the properties of ceramic fine aggregate are well within the range of values of concrete making aggregates.

Keywords- Compressive strength, Split tensile strength, Ceramic fine aggregate

Title: DIFFUSION EQUATION AND COMPLEMENTARY SCHRODINGER’S EQUATION FROM BROWNIAN MOTION

Authors: B.S.Rajput

ABSTRACT
Diffusion Equation and classical Schrödinger Equation have been derived from Brownian motion and the quantum limits have been derived, which transform the classical Schrödinger equation in to usual quantum equation without any formal analytic continuation and wave- particle duality. These quantum limits have been
shown to lead to Heisenberg uncertainty relation between position and momentum of the Brownian particle. PACs.No.03.65-w; 03.65 Ca ; 03.65 Ta

Title: Financial and economic crisis creates new data on the electricity for remote consumers: Case study Greece

Authors: Jacob G. Fantidis, Pantelis Antoniadis, Contsantinos Potolias, Dimitrios V. Bandekas, Nicolaos Vordos

Abstract—The financial and economic crisis in Greece has brought new taxes on the fossil fuels. During the depression (January 2009 – June 2011) the diesel-oil price was rising more than 65%. The aim of this study is to investigate how this crisis has affected the electricity cost for a remote consumer. The HOMER software was used in order to find the optimum hybrid system for a typical country house in four different Greek Islands. The generality of Greek Islands are suitable for exploitation of wind energy for electricity generation. Due to the dramatically
increased prices for diesel-oil over the last two years in Greece, the PV generators offer not only environmental benefits but also provide lower cost of energy and can displace the diesel engine generators.

Title: Aerodynamic Design of a HAWT Blade for Indian Wind Condition

Authors: Nitin Tenguria, Dr. N.D. Mittal, Dr. Siraj Ahmed

Abstract— Wind turbine works by converting the kinetic energy of the wind into electrical energy that can be supplied. Present work gives an optimization method for blade of VESTAS 1.65 MW horizontal axis wind turbine according to Indian wind condition which is not as good as European countries. For doing this optimization the theory used is Blade Element Momentum (BEM) Theory. In this work the profile taken is NACA 634-221 and the data are evaluated according
to the properties of this profile. Computer program is developed for getting power coefficient curve with varying parameters such as tip speed ratio, lift and drag coefficients. Other parameter like chord distribution and twist distribution is also optimized for good performance. Results are compared with experimental data found in literature.

Title: Corrosion behaviour of carbon steel in Hexane Sulphonicacid

Authors: C. Mary Anbarasi, S. Rajendran

Abstract— This research aims to study the corrosion inhibition efficiency of Sodium 1- Hexane Sulphonic acid as its sodium salt (SHXS) – Zinc ions (Zn2+) system in dam water (Tamil Nadu, India) using weight loss method. A synergistic effect exists between SHXS and Zn2+. The influence of sodium potassium tartrate (SPT) on the Inhibition efficiency (IE) of the SHXS-Zn2+ system has been evaluated. As the immersion period increases IE decreases. The nature of the metal surface has been analysed by scanning electron microscope. A mechanism is proposed to explain the inhibitory action of the corrosion inhibitor. The protective film is found to be UV fluorescent.

Title : Wireless Sensor Network for snow-met data monitoring in Indian Himalayas – A Review

Authors : Moiz Chasmai, Rajiv Das, Rajesh Garg, Mandeep Kaur

Abstract— Appreciating the future possibilities, Wireless Sensor Networks (WSN) is important as it connects the physical world of our surroundings to the vast computing & storage resources. Today, WSN is being used in military, industries, technical institutions and commercial applications, such as remote sensing applications for data collection, industrial process monitoring and control, machine health monitoring [1], environment and habitat monitoring, healthcare applications, home automation, and traffic control [2],[3]. Snow & Avalanche Study Establishment’s (SASE) requirement is to study the snow bound areas in the Indian Himalayan terrain which in turn helps to prepare avalanche forecasts by collecting the snow and meteorological parameters during winter. In this conceptual paper, we have proposed to go for WSN solution for acquisition of snow-met parameters which can overcome the drawbacks of conventional established telemetry systems and improve upon data collection. Successful implementation of this network in the field will help in analyzing the snow conditions in a better way by collecting more useful data along the avalanche prone zones in the Himalayas.
