Abstract

Present study has been made to investigate seasonal variations of water quality parameters in drinking water from some borewells in Kolhapur city. The samples were collected during the year 2005-2006 in summer, rainy and winter seasons. The water samples were analysed for various parameters such as pH, E.C., dissolved oxygen, alkalinity, chloride, total dissolved solids (TDS), total hardness, calcium, magnesium and sulphate etc. Certain parameters were higher than the permissible limit recommended by World Health Organisation (WHO) and BIS. The Study revealed significant changes in water quality during different seasons of in a year.

Abstract

Kolhapur city is one of the industrial cities where different metal processing units such as machine fabricating and electroplating units are working from last many years. The present paper deals with water quality analysis of underground water from some bore wells located in Shivaji Udyamnagar Industrial area. The Physico-chemical parameters such as temperature, pH, turbidity, electric conductivity, dissolved oxygen, carbon dioxide, chemical oxygen demand (COD), biochemical oxygen demand (BOD), hardness, calcium, magnesium, chlorides, total solids (TS), total dissolved solids (TDS), sulphate, nitrate, phosphate and sodium were studied along with iron and lead. The bacteriological study of water such as MPN, SPC and E. coli were carried out from four sampling sites. The results were compared with WHO and ICMR standards. The results reveal that effluent discharge from industries may be responsible for changing the water quality.

Abstract

Objectives: The present paper aims at finding the influence of soil slope on reduction of horizontal (lateral) load carrying capacity of pile embedded at the crest of clay slope. Analysis: 3D finite element analysis has been carried out using PLAXIS 3D. In each analysis, initial stresses developed due to gravity loading are calculated in the first step. In the second step, pile construction is simulated by interchanging the material properties of the appropriate volume elements. Finally, lateral load corresponding to the prescribed horizontal deflection of 0.1D at pile top is calculated in last step. Findings: The effect of various factors such as slope angle, Length to Diameter ratio of pile and undrained cohesion of soil on horizontal load carrying capacity of pile has been studied. From the study, it is perceived that the load carrying capacity for a prescribed displacement increases with increase in length to diameter ratio and undrained cohesion whereas capacity reduces with increase in slope angle. There is approximately 10% and 27% decrease in the load carrying capacity when the slope angle changes from 0º to 30º and 0º to 55º respectively. For pile having L/D = 10, the deflections are observed throughout the length of the pile where as for pile having L/D = 25, the deflections are extending up to certain depth and after that depth, the deflection is zero. Applications/Improvement: Effect of sloping ground condition on pile response is quantified by numerical analysis. Reduction in the ultimate capacity for sloping ground condition is presented for range of parameters.It is possible to predict the pile response for sloping ground condition for a given pile response in horizontal ground and predicted reduction from tables.

Abstract

The objective of the present study was to investigate the hepatoprotective activity of alcoholic and ethyl acetate leaves extract of Ziziphus mauriatiana against paracetamol induced hepatotoxicity. The material was dried in shade, they were powdred and extracted with alcohol and ethyl acetate. Preliminary phytochemical tests were done in the presence of phytoconstituents like flavonoids, saponins, phenolic compounds and tannins. The present activity on rats shown alteration in the level of biochemical markers of hepatic damage like ALT, AST, ALP, Bilirubin and Protin were tested in both paracetamol treated and untreated groups. Wistar rats were induced hepatotoxicity by oral administration of paracetamol (640mg/kg) for 10 days. The hepatotoxicity induced rats were used for the studies. Ethyl acetate extract (400mg/kg), ethanol extract (300mg/kg) and standard (Silymarin) reduced the elevated levels of enzyme markers such as AST, ALT, ALP, and total bilirubin and increased in total proteins levels. The histopathological investigations also supported above effect of ethyl acetate and ethanolic extract by indicating the reduction in inflammatory collection and absence of fatty vacuoles in liver sections.

Abstract

Construction of embankment on soft soil is one of the biggest challenges faced by geo technical engineers. Soft soil is being one of the most erratic soils with very low bearing capacity and high compressibility. Attempts have been made to study the phenomenon of soil structure interaction for embankment built on soft soil improved with stone columns through full scale models, laboratory models and various numerical simulations. However, full scale model studies may prove to be uneconomical in most cases of embankment construction except in case of highly funded projects. Hence experiments and numerical simulations using appropriate numerical method (FEM/FDM) is generally deployed to study such complex interaction behaviour. In the present study, it is aimed to carry out a detailed parametric study to critically examine the effects of various key parameters of soft soil and stone column considering linear behaviour.
