Abstract: PVP polymers containing Li+ or Ag+ Ions have been synthesized in good stability and transparency by using the solution casting method. Their structural, optical, thermal and electrical properties have been investigated from the measurement of XRD, FTIR, SEM, EDAX, optical absorption spectra, TG-DTA profiles and impedance spectral features in order to evaluate their potentialities for their use in electrochemical display device applications.

To study the socio demographic profile of road traffic accident victims in district hospital, karimnagar
P V Srinivasa Kumar,K Srinivasan
International Journal of Research and Development of Health , 2013,
Abstract: Introduction: Road traffic injuries are a major but neglected global public health problem, requiring concerted efforts for effective and sustainable prevention. Of all the systems that people have to deal with on a daily basis, road transport is the most complex and the most dangerous. Materials & Methods: A cross sectional study was conducted to evaluate socio demographic characteristics, among the RTA victims admitted in district hospital, Karimnagar. Results: A total of 370 road traffic accident victims were interviewed by the end of study period. In this study, it was found that most of the RTA 192 (52.5%) cases were belonging to the age group of 21-30 years, followed by 96 (26.2%) in age group of 31-40 years and 42 (11.5%) in age group of 11-20 years.Conclusion: Guiding and implementing traffic related rules through counselling, health education, road shows etc., will have a great effect in controlling road traffic accidents. A small effort will have a big impact in the present scenario.
NaHSO4-SiO2 as an efficient and chemoselective catalyst, for the synthesis of acylal from aldehydes under, solvent-free conditions

Abstract: Both aromatic and aliphatic aldehydes reacts smoothly with acetic anhydride in presence of silica supported sodium hydrogen sulphate to afford the corresponding 1,1-diacetates in good to excellent yields. We studied competitive reactions for the acylation of aldehydes in the presence of ketones using silica supported sodium hydrogen sulphate as a catalyst. Using this catalytic system, the highly selective conversion of an aldehyde in the presence of ketone was observed.NaHSO4-SiO2 is a chemoselective and highly efficient catalyst for acylal formation from aldehydes. The advantages of this methodology over the reported methods is the availability of the starting materials, simplicity of acylation procedure, a clean work-up, a short reaction time, high yields and reusability.The concept of green chemistry has been playing an important role in recent years for meeting the fundamental scientific challenges of protecting the living environment. One of the thrust areas for achieving this target is to explore alternative reaction conditions and reaction media to accomplish the desired chemical transformation with almost negligible by products and waste generation as well as elimination of the use of volatile and toxic organic solvents. It is therefore of utmost importance to evolve a simple and effective methodology for the different organic transformations that cover the concept of green chemistry.During the multi-step synthesis, the protection of the carbonyl group is widely achieved by the formation of acylal (1,1-diacetate) [1]. These substrates are important because of their application as precursors for the synthesis of 1-acetoxy dienes, valuable synthetic intermediates for Diels-Alder cycloaddition reactions [2]. The relative acid stability of acylal is another interesting feature in the field of protection and deprotection chemistry. General, acylals are prepared by treating aldehydes with acetic anhydride in the presence of protonic acids [3], Lewis acids [4], het

Training Of Artificial Neural Networksin Data Mining
K Raja Sekhar,,V Srinivasa Kalyan,,B Phanindra Kumar
International Journal of Innovative Technology and Exploring Engineering , 2013,
Abstract: Companies have been collecting data for decades, building massive data warehouses in which to store it. Even though this data is available, very few companies have been able to realize the actual value stored in it. The question these companies are asking is how to extract this value. The answer is Data mining. There are many technologies available to data mining practitioners, including Artificial Neural Networks, Regression, and Decision Trees. Many practitioners are wary of Neural Networks due to their black box nature, even though they have proven themselves in many situations. This paper is an overview of artificial neural networks and questions their position as a preferred tool by data mining practitioners.
Studies on Permeability of Self-Healing Built-In Bacteria Concrete
Srinivasa Reddy V,K.S Jyothi Kumar,M.V. Seshagiri Rao,Ch Sasikala
International Journal of Recent Technology and Engineering , 2013,
Abstract: Permeability is the most crucial internal factor in concrete durability. The durability of a concrete is closely related to its permeability. The permeability dictates the rate at which aggressive agents can penetrate to attack the concrete and the steel reinforcement. Water penetrability is defined as the degree to which a material permits the transport gases, liquids or ionic species through it. Water can be harmful for concrete, because of its ability to leach calcium hydroxide from the cement paste, to carry harmful dissolved species such as chlorides or acids into the concrete, to form ice in large pores in the paste, and to cause leaching of compounds from the concrete. Water absorption, sorptivity and water permeability measurement are some methods to determine the water penetrability of concrete. A triaxial cell permeability apparatus and method for determining water permeability of concrete are presented in this paper. This method utilizes Darcy’s Law for steady flow so as to relate water permeability to the rate of water flow under a pressure head. The major drawbacks commonly encountered in triaxial cell permeability apparatus are addressed by evaluating the water permeability as per as per German standard DIN 1048(Part 5):1991 specifications and MORT&H (Ministry of Road Transport & Highways) 4th Revision specifications. Test results indicated that bacterial concrete is highly impermeable than normal concrete. Permeability measurement techniques and durability modeling are based on the Darcy equation for permeability based on measurement of flow rate, and the Valetta equation for permeability based on measurement of penetration depth and time. Bacteria built-in concrete works on the phenomenon of microbiologically induced calcite precipitation. Calcite crystals formed, due to microbial activities of bacteria Bacillus subtilus JC3, seals the cracks and pores in concrete and enhances the strength and durability of concrete by making concrete impermeable to transport different fluids or gases, like water, chlorides, sulfates or oxygen.

Journal of Engineering and Applied Sciences , 2010,
Abstract: Mueller Matrix Imaging Polarimetry is a powerful imaging technique used to provide high precision measurements for the Mueller matrices at every pixel of an image captured with a detector. The system used acquires 16 Mueller Matrix images and these images are further processed to investigate the polarization properties of the sample under consideration. In this communication the optical system used to acquire the Mueller Matrix Images functioning in reflection frame is described and the resulting polarization character of the wood sample is presented.
AN ALTERNATIVE APPROACH TO DESIGN AND ANALYSIS OF BROADBAND BEAMSPACE ADAPTIVE ARRAYS
A. S. SRINIVASA RAO,P. MALLIKARJUNA RAO,E. JAYA,V. ASHOK KUMAR
International Journal of Engineering Science and Technology , 2011,
Abstract: The beamwidth of a linear array depends on number of elements in the array and frequency of the input signal. At present designing of wideband antennas and beamformers became important, in the fields of microphone arrays intended for teleconferencing, in transmitting or receiving spread spectrum signals, crip signals etc. A beamspace adaptive planar array for broadband beamforming is proposed based on the filter – and - sum beamforming technique. A detailed design method was provided for both the linear arrays and the adaptivearrays and simulation results are provided for the proposed method. Our proposed method is used to demonstrate that the beam-space adaptive array can suppress interference signals having a wide fractional bandwidth and that the array has fast convergence.
