Abstract: Concentration of gaseous pollutant and particulate matter are the major cause of respiratory disease and deaths. The dust pollution is serious matter almost in all cities of Maharashtra. This paper deals with the results of ambient monitoring of Aurangabad city for particulate matter, sulphur dioxide and nitrogen dioxide. The sulphur dioxide concentration is measured by Modified West and Geake Method whereas nitrogen dioxide is measured by Modified Jacob and Hochheiser method. The results shows a very high concentration of particulate matter, however sulphur dioxide and nitrogen dioxide were within the permissible limits.

Abstract: The alternative energy sources are new option in front of world to overcome energy crisis and pollution related issues. The solar energy, wind energy and bio mass are three major sources and out of these three energy sources solar energy is the easiest source to extract useful energy because the wind energy can be useful particularly in coastal area where there is high wind velocity and energy extraction bio mass needs either chemical conversion or thermo chemical conversion process. The objective of present work is to developed solar distillation system consists of wax as phase change material to improve the thermal performance.

Abstract: Exhaust manifold is one of the most critical components of an IC Engine. The functioning of exhaust manifold is complex and is dependent on many parameters viz. back pressure, exhaust velocity, scavenging etc. In the present work, the performance of a four-stroke four cylinder gasoline engine exhaust manifold have been analysed using three different fuels - gasoline, alcohol, and LPG for the estimation of flow characteristics, thermal characteristics, and minimum back pressure. The manifold modelling is done in Creo2.0 followed by meshing and analysis in ANSYS. The LPG fuel gives minimum back pressure, temperature and velocity being approximately in the same range for all three fuels viz. gasoline, alcohol and LPG. Thus, LPG can be considered as a suitable alternative for gasoline in terms of minimum back flow in manifold.

Abstract: It is believed that there is a growing mismatch between design features of the furniture used in the classrooms and the anthropometric parameters of the students. Bureau of Indian Standards has specified a dimension of school furniture taking into consideration the anthropometric dimensions of the Indian students and ergonomic design principles in IS 4837:1990. The objective of the present study is to evaluate the existing school furniture with reference to IS 4837:1990. The authors have proposed a new methodology for ergonomic assessment of the school desks. A new concept of Ergonomic Quality Assessment Index (EQAI) is developed. Accordingly, the school desks from the three schools located in Solapur city from the state of Maharashtra in India is evaluated..............

Abstract: This paper presents comparative study of elevated water tanks subjected to dynamic loading supported on RC framed structure and concrete shaft structure with different capacities and placed in different seismic zones. History of earthquake reveals that it have caused numerous losses to the life of people in its active time, and also post earthquake time have let people suffer due to damages caused to the public utility services. Either in urban or rural areas elevated water tanks forms integral part of water supply scheme, so its functionality pre and post earthquake remains equally important.................

Abstract: Bamboo is very cheap, easily available, and available in ample quantity. Bamboo is cultivated in farm by farmers. Bamboo is having very good mechanical properties which attract many researchers to use it as reinforcing material in concrete. From bamboo small thin strips were prepared. These strips were tied together in two directions to form a bamboo-strip-mat. All these strips while making bamboo-strip-mat was tied together with small thin Mild Steel wire to ensure their position in mat formation. In this paper study is presented using bamboo-strip-mat as reinforcement in cement concrete prismatic section at bottom side. Concrete beams thus produced in laboratory were tested in flexure; results obtained were presented in this paper. Bamboo strips were prepared from old age bamboo..........

Abstract: The present fossil fuel crisis and increasing vehicle population made us to think of alternate fuels. The abundance of the fossil fuels is expected to be exhaust in another 30-40 years. The cost of the fossil fuels is day by day increasing and also the emission from these fuels increases the air pollution. With keeping in view of all the above said points, it is made us to think of alternate fuels for all CI Engines. Among alternate fuels, the Pine oil blended with Methanol will promise for substituting the diesel. With pure vegetable oils there is combustion problems and which leads to more emissions in the exhaust. The present investigation evaluates Pine oil blended with Methanol in Diesel Engine.........
