Genomic Data is growing very rapidly with the sequencing of genomes of various forms of life. To understand the overwhelming data and to obtain meaningful information, Data Mining techniques such as Principal Component Analysis and Discriminant Analysis are used for the purpose. Data Mining is basically used when the data is vast and there is need to extract the hidden knowledge in the form of useful patterns. The data set taken into consideration is protein data pertaining to diabetes mellitus obtained from a database. The task at hand was to find out in which species most of the diabetes related proteins exist. It so happened that most of these proteins were prevalent in Human Beings, House Mice and Norway Rat as they are all mammals and Human Beings have orthologs as House Mice and Norway Rat. Both these techniques prove that human beings show a variation from those of House Mice and Norway Rat which are similar in terms of the variation of protein attributes. This can also be inferred from statistical analysis by using histograms and bivariate plots. Other Data Mining Techniques such as Regression and Clustering can be used to further explore the above inference. © 2011 Research Society for Study of Diabetes in India.

The model proposed by Lu and Maurer (1993) for aqueous electrolyte solutions is extended to calculate excess Gibbs energy values of some aqueous Sulphates,Chlorides and Nitrates whose mean activity and osmotic coefficient values are evaluated from Pitzer's model. All excess Gibbs energy values are negative in sign. Hence the system is tending to absorb energy from environmental source point and is performing work on the system to create internal physiochemical changes. The plots presented also revealed that this absorption of energy is progressively increasing. © 2013 RASAYAN. All rights reserved.

The rapid development in the industrial sector leading to the drastic changes in the environmental equilibrium and is the prime challenge to scientists as the natural resources are very precious. The paper industrial effluent mainly shows an adverse effect on the water quality parameters like D.O., B.O.D., C.O.D., pH, temperature and conductivity of the surrounding aqua systems at the time of discharge. The abnormal levels of these parameters cause pollution in water bodies and even death of aqua flora and fauna. However, paper industrial effluents are found hazardous and they enter the environment through various channels of waste water discharges. Conventional treatment technologies for the removal of industrial effluents are less economical than that of biological methods. Phytoremediation techniques have been found potential to absorb effluents to maximum extent and without possibility of secondary pollution. The prime objective of this paper is to investigate the capability of selected aquatic plant species of Eichhornia and Pistia for the removal of paper effluent toxicity from the contaminated aqueous environment. The changes in the water quality parameters during the treatment of industrial effluent with aquatic plants were verified periodically to optimize the process. © Global Science Publications.

In this paper an analytical procedure is developed to investigate the bending characteristics of laminated composite plates based on higher order shear displacement model with zig-zag function. This zig-zag function improves slope discontinuities at the interfaces of laminated composite plates. The equation of motion is obtained using the dynamic version of Hamilton's principle. The solutions are obtained using Navier's and numerical methods for anti-symmetric cross-ply and angle-ply laminates with a specific type of simply supported boundary conditions SS-1 and SS-2, respectively. In this paper the numerical results are presented for bending of anti-symmetric cross-ply and angle-ply laminated plates. All the solutions presented are close agreement with the theory of elasticity and closed form solutions available in the literature. © 2006-2011 Asian Research Publishing Network (ARPN).

The discharges of effluent wastewater from the different industries originate adverse effects to the environment and leads to imbalance of bio-systems. Azo compounds are extensively being used as dyes in carpet and textile industries, the water effluent discharges from these industries leading to the water pollution in the surrounding water bodies. The conventional treatment technologies for the removal of these dye substances are less economical and cause secondary pollution. Presently, researchers have become increasingly interested to degrade azo. compounds by using suitable microbial treatment technologies. The main objective of this paper is to study the capabilities of free, immobilized and co-immobilized cells of Saccharomyces cerevisiae and Lactobacillus sporogenes for the decolourization and degradation of an azo compound "Congo Red" (CR) from aqueous solutions. The experimental data' evidences that the degradation of azo compound is highly possible with the selected microbial strains and it is more with co-immobilized cells of the selected strains. The influence of various factors'viz., pH and initial concentration of biomass on the degradation were verified for the optimization of the process. © Global Science Publications.

Fiber-reinforced polymer composites have played a dominant role for a longtime in a variety of applications for their high specific strength and modulus. The fiber which serves as a reinforcement in reinforced plastics may be synthetic or natural. Past studies show that only synthetic fibers such as glass, carbon etc., have been used in fiber-reinforced plastics. Although glass and other synthetic fiber-reinforced plastics possess high specific strength, their fields of application are very limited because of their inherent higher cost of production. An attempt has been made to utilize the coir, as natural fiber abundantly available in India. Natural fibers are not only strong and lightweight but also relatively very cheap. The present work describes the development and characterization of a new set of natural fiber based polyester composites consisting of coir as reinforcement and epoxy resin. Coir composites are developed and their mechanical properties are evaluated, at five different volume fractions and tests were carried out and the results were presented. Experimental results showed tensile, static and Dynamic properties of the composites are greatly influenced by increasing the percentage of reinforcement, and indicate coir can be used as potential reinforcing material for many structural and non-structural applications. © (2013) Trans Tech Publications, Switzerland.

Digital image watermarking is a copyright protection technology expected at asserting intellectual property rights of digital images by embedding a copyright identifier in the contents of the image, without disturbing its quality. In this paper, a new robust and secure color watermarking scheme based on Discrete Wavelet domain is proposed. The RGB color space is converted into HSV color space and the H component is decomposition with 'Haar' which is simple, symmetric and orthogonal wavelet. The proposed embedding process, the scrambled watermark is embedded in the modification of the extraordinary value of LL band and LH band of H component to the watermarking scheme which excellent preserves the quality. The supplementary improvement of the proposed technique is taking advantage of HVS which can adaptively regulate the watermark embedding strength. Experimental results show that the method not only has better transparency, but also has good robustness such as noise, compression, filtering, cropping.

This paper presents an effective color image retrieval scheme by contrast based texture features, which achieves higher retrieval efficiency. The proposed method Texture Spectrum in Wavelet (TSW) domain is very fast to compute and enable to speed up the wavelet computation phase for thousands of sliding windows of varying sizes in an image. Proposed TSW provides a robust contrast features for image retrieval from a lot of objects in an image can be distinguished solely by their textures without any other information. The proposed system divides the lower resolution approximation image into four sections, where each section extracts 12 contrast features and stores the features of the query image and also all images in the database and extracts the features of each image. The proposed TSW method reduces the computation of possible patterns as well as fast and retrieving accurate images. Experimental results show that the proposed method for image retrieval is more accurate, efficient and quite understandable in spite of the availability of the existing retrieving algorithms.

Wastewater discharges from several industries originate severe detrimental effects to the environment and leads to imbalance of bio-systems. Azo compounds are extensively being used as dyes in carpet and textile industries, the discharges from these industries leads to the detrimental effects. Conventional technological methods for the removal of dye stuffs found less economical. Biodegradation researchers have become increasingly interested to macerate azo compounds by applying suitable microbial treatment. This paper is aimed to study the efficacy of free cells of a microorganism, Halobacterium cutirubrum for the decolorization and degradation of a few azo compounds, Methyl Red (MR), Methyl Orange (MO) and Congo Red (CR) from aqueous solutions. The experimental data evidences that the degradation of azo compounds is highly possible with the selected microbial mass and is structural dependant. A suitable mechanism for the degradation path of azo compounds is suggested. The influence of various factors viz., pH, initial concentration of biomass and external additives on the degradation were verified for the optimization of the process. © Global Science Publications.

The present study has been aimed to screen the sub acute toxicity of a combination pesticide polytrin C which contains an organophosphate and a pyrethroid. First combination pesticide acute studies were carried out in Wistar rats to fix up to LD50 dosage. Polytrin-C show a lesser toxicity when compare to the earlier literature available regarding the toxicity of its constituents profenofos and cypermethrin. Plasma AChE showed a prominent decrease in the both male and female rats of group 4 (34 mg kg-1 b.wt.) while a dose dependent decrease of blood AChE was observed only in female rats, the males showing a decrease only in the highest dose group (34 mg kg-1 b.wt.). In brain, a dose dependent decrease of AChE activity was observed in both male and female rats treated with the pesticide at the doses of 17 and 34 mg kg-1 b.wt. (G3, G4) while the lowest dose group of 8.5 mg kg-1 b.wt. remained on par with the untreated control. The study also revealed that the combination pesticides behave differently and exhibit a different toxicological profile when compared with the toxicity of the individual pesticides in the combination. © 2011 Academic Journals Inc.
