The present article discuses the problems of relativistic invariance and commutation relations at unitary quantum theory. The scalar analogue of the main (principal) equation of the unitary quantum theory together with the Poisson equation are solved numerically in this paper. The value of the electrical charge and also the fine-structure constant, are found, which are in good agreement with the experiment. The evaluation of the electrical form factor end the mass of such a particle is also carried out.

This experiment was done for investigate the histopathological effects of bisphenol A exposure on testis tissue of guppy fish. In this study 90 guppies were examined in 2 experimental groups. In experiment groups, guppies exposed 4 mg/L and 8 mg/L BPA doses and after 96 hours fishes were sacrified. Tissues were dissected out, fixed in Bouin’s fixative, stained with Hematoksilen & Eosin, and examined using light microscopy. It is observed that deterioration, atresia and decreased in the number of seminiferous tubules in experiment groups.. In addition, openings between seminiferous tubules, increase in distance between tubules and decrease in the number of spermatogonium were detected.

In this paper, we report a combined experimental and theoretical study on molecular structure; vibrational spectra of 2-hydroxy-3,5-dichlorobenzaldehyde (HDCB) have been recorded using Fourier transform infrared (FT-IR) and FT-Raman spectra in the region of 4000?400 cm^?1 and 3500?100 cm^?1, respectively. The conformational stability, molecular geometry and harmonic vibrational frequencies were obtained by HF/6-31++G(d,p) and B3LYP/6-31++G(d,p) basis set. The calculated harmonic vibrational frequencies were compared with experimental FTIR and FT-Raman fundamentals. The observed and calculated frequencies are found to be in good agreement. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecule. The thermodynamic functions from spectroscopic data by statistical methods were obtained for the range of temperature 100 – 1000K.

Hypothyroidism is a progressive metabolic disorder associated with decreased levels of T3 and T4 and increased TSH level. It is a common disease seen in females compared to males. Hypothyroidism being a metabolic disorder is associated with oxidative stress, which involves generation of free radials. The thyroid gland produces H2O2 by NADPH Oxidase system of the membrane and it utilizes H2O2 as a substrate of thyroid peroxidase (TPO) for thyroid hormone formation. In the present study T3, T4 and TSH was estimated to establish hypothyroidism and MDA and vitamin C to the asses the oxidative stress and anti-oxidant status respectively in the individuals. The study revealed an increased level of malondialdehyde (MDA) and a significant depression in antioxidant status.

The rapidly depleting fossil fuels have simulated the worldwide search for the renewable alternative fuels. Our country is an agriculture based one and the production of sugar cane is more. In the production of sugar from sugar cane, alcohol will be produced as a byproduct. This made alcohol as a perfect replacement because these are derived from indigenous sources and are renewable. But with the low cetane number and high self ignition temperatures, the burning of alcohols in the existing diesel engines is difficult because for the vaporization it absorbs more heat from the engine and makes the engine cool and further more ignition delays. This made the ignition of alcohol in the high temperature combustion chambers. So in our work an insulated diesel engine is developed which retains higher temperatures in the combustion chambers and aids for the combustion. This reduces the ignition delays and leads for the complete combustion and further improves the thermal efficiency and reduces the emissions. The complete experimentation has done on a single cylinder 4-stroke water cooled 3.68 KW Kirloskar diesel engine with alcohol as a fuel. Due to lower viscosity of alcohol the fuel injection pressure is reduced to165 bar for the experimentation. In the experimentation it is observed that maximum heat lost through the piston. So three different piston crowns made up of Nimonic alloy, Copper and Brass are tried on the test engine with an objective to find the best one in terms of performance and emissions with alcohol as fuel and the same is compared with aluminum piston. Among all the pistons the brass piston performed well. Further the efficiency of the engine can be improved by providing turbulence in the combustion chamber. So for the experimentation maximum number of nine grooves is made on the brass piston and is tested. For the comparison the engine is also operated with aluminum piston. Out of all these pistons tested, brass Piston with nine grooves is found to be the best in terms of efficiency and emissions.

Brahiminism remains a pervasive force in the works of U.R. Ananthamurthy. The places where Brahiminism is strong remain undeveloped with Brahmins becoming a part of unproductive society. Ananthamurthy’s works show that Brahmins remain a backward and unproductive society because of orthodoxy. Ananthamurthy’s heroes rebel against the oppressive system and try to justify their existence by rebelling against the customs. Incidentally all the heroes are Brahmins who know their society intimately, but they are liberal, open-minded and modern individuals who understand that if the Brahmins have to prosper in the modern world then they have to shun their attitude and fit into the modern economic system. The current paper studies different works of U.R. Ananthamurthy and shows how his heroes develop recalcitrance while trying to wake up their society to the evils that emanate from their anachronic customs and professions.

The definition of the Drazin inverse of a square matrix with complex elements is extended to Con-s-k-EP matrices by showing that for any B and W, n by n respectively, there exists a unique matrix, X, such that for some positive integer k, , and . Various expressions satisfied by B,W,X and related matrices are developed.

The antibacterial properties of picolinic acid was tested against selected test organisms which includes serratia marcescens, micrococcus luteus, proteus vulgaris, proteus mirabilis, bacillus cereus, bacillus subtilis, klebsiella pneumoniae, escherichia coli, shigella flexneri, lactococcus lactis, enterobacter cloacae, staphylococcus aureus. The results obtained established that picolinic acid has antibacterial activities against S. marcescens, K. pneumoniae, E. coli, S. flexneri, B .cereus, P. vulgaris, M . luteus with minimum inhibitory concentration of 0.5mg/mL. It also had great antibacterial activity against P. mirabilis at minimum inhibitory concentration of 1.5mg/L. Picolinic acid evoked a strong antibacterial activities against B. subtilis, S.aureus and L. lactis at minimum inhibitory concentration of 2.0mg/mL and against E . cloacace at minimum inhibitory concentration of 1.0mg/mL. The diameter of zones of inhibition ranges between 7.0mm and 14.0mm.

Surface and underground water, veritable sources of drinking water to the Ikono inhabitants were investigated. Water samples were collected randomly from the area within a period of 30days and characterized for various physical, chemical and microbial parameters including nitrate, pH, total dissolved solid (TDS), total hardness, calcium, magnesium, chloride and total alkalinity and E. coli. Results showed variability in chemical and biological composition and informed that water sources were not polluted when compared with reference standards which serves as guidelines with respect to parameters examined. However, some points showed elevated microbial count which indicates some level of pollution of water points with human faeces and other warm blooded animals. From the result of the analysis, water in most parts of the area is fit for drinking and other domestic purposes.
