Solar photo catalytic degradation of environmental contaminants

Solar energy has been proved as an innovative and promising route for the treatment of industrial effluents, waste water and for the purification of water. The solar detoxification process has challenged the effectiveness of conventional treatment processes for the degradation of environmental contaminants. The literature review of scientific and technological aspects on solar photo catalytic degradation and detoxification process has been conducted and briefly represented in the present paper. Key words: Solar detoxification, effluent, metal oxide, photo-catalysis, spent wash

Free Vibration Analysis of a Rectangular Duct with Different Axial Boundary Conditions

3This paper describes the free vibration analysis of a rectangular duct by using the Rayleigh-Ritz method. Static beam functions are used as admissible functions in the Rayleigh-Ritz method. These basis functions are the static solutions of a point-supported beam under a series of sinusoidal loads. The unique advantage of using this method is that it allows for the consideration of different axial boundary conditions of a duct. Computational results are validated with existing literature data for a simply supported rectangular duct and the finite element method (FEM) for other axial boundary conditions. A validated analytical model is used for generating natural frequency data for different dimensions of rectangular ducts. Further curve fitting has been done for the generated data, and an empirical relation has been presented to calculate the first fundamental natural frequency for different material properties of ducts and different axial boundary conditions, which can be used for any dimensions of the duct within the specified range

Diversity of Birds in Local Ecosystem Aurangabad, Maharashtra, India

Dr. B. A. M. University, Aurangabad is having very good biodiversity having a different type of flora and fauna. It surrounded by hilly area having two small water bodies and different type of flowering and fruit plants on its surrounding campus which provides grounds for feeding, breeding and nesting for avian fauna. The field survey was made to assess the campus for the avian fauna by conducting daily observations. During field survey the about 61 species of birds were recorded in all seasons due to different habitats present at university campus, out of watershed catchments, from flowering tree shelters, and from marshy areas. Out of these, some are common birds which are observed perennially like Pond heron, Cattle egret, White breasted kingfisher, Red wattled lapwing, Indian ring dove, Crow pheasant, Jungle babbler, Common myna, Rose ringed parakeet, Tailor bird, Purple rumped sunbird, Indian robin, Magpie robin. Some birds are seasonal like Black Ibis, European hoopoe, Coppersmith barbet. These are more frequently observed in winter. Grey hornbill, Tree pie are seen in starting of Rainy season. The University campus is having rich diversity of avian fauna

Utilization of skin of 'Koth', Otolithoides biauritus - a new fish by-product

Dasyatis uarnak (banded whip-tail stingray)skin is being used as another alternative sources for leather.The skin of Koth and Ghol is used for this purpose and the finished product is used in the manufacture of purses,belts etc

Utilization of head and vertebrae of Otolithoides biauritus - a new economic resource

Otolithoides biauritus, locally called as koth is an important resource in Maharashtra. Exploited by multi-day trawlers, the resource is abundant throughout the year with peak landings during the period of October-December, at New Ferry Wharf landing centre. These trawlers are operated at a depth of 40-60 m, 80-90 km off north-west coast. The total length of the fish in trawl landings usually ranges between 90-150 cm
