With the recent emphasis on infrastructure development, geosynthetics in India have received a tremendous boost. Apart from the consistent use in pavements of the east-west and north-south corridors and golden quadrilateral of the NHDP projects being executed by the NHAI, reinforced soil walls in urban flyover approaches have become common, due to their distinct advantages over conventional reinforced concrete walls. These apart, the use of high strength geotextiles and geocell mattresses for foundation of high embankments on soft soils has also proven to be feasible even in black cotton soil areas. Increasing emphasis is being given to the development and use of natural fibre (particularly, jute and coir) geotextiles for civil engineering applications. The paper traces many of these developments and summarizes the key issues to be taken note of for utilizing the vast potential geosynthetics offer, in India's march to development.

Global environmental concerns and the escalating demand for energy, coupled with steady progress in renewable energy technologies, are opening up new opportunities for utilization of renewable energy resources. Solar energy is the most abundant, inexhaustible and clean of all the renewable energy resources till date. The power from sun intercepted by the earth is many times larger than the present rate of all the energy consumption. Solar Photovoltaic Technology is one of the finest ways to harness the solar power.. A significant amount of research and development work on the Solar Photovoltaic Technology has been done since the 1970s after the major energy crisis in the world. Many innovative systems and products have been put forward and their quality evaluated by academics and professionals. In the modern era renewable energy generation technologies have broad societal impact and need to be assessed considering multiple perspectives including: social, technological, economic, environmental, and political. Assessment of energy technologies is a complex process because it is based on multiple criteria and multiple decision makers, and usually requires analytical models. Recent developments suggest that thin film crystalline silicon is becoming a material for future. This paper reviews the photovoltaic technology, its power generating capability, its environmental aspect coupled with a variety of its applications.

Through the years there has been an increment in the huge amount of power transfers and third party approaches. Despite the fact, electric power transmission facilities throughout the world are not openly allowed to progress because of the different environmental, land-use and regulatory pressures that arise. As a result upholds in transmission, irregular facility usage, and undesirable parallel pathways or loop movements are being experienced. When there is an increase in power transfer the operating system becomes difficult to manage ultimately becomes complex. Because of this complexity the control on the system becomes weak and the power transfer can become insecure in case of huge power movements.

This paper present energy audit process on water treatment plant in Lalpur, Jabalpur M.P, here more effective equipment use for water purification/water distributed to Jabalpur area. Water treatment plant has been highly energy and cost intensive. The water treatment plant requires 8760 h per year of the total operating hours to produce 35405 mld (million litter per day). To achieve effective and efficient energy management scheme, thermal energy audit analysis was employed on water treatment plant. The industrial sector is the largest users of energy around the world and its share in the overall consumption is 49%. Energy is one of the major inputs for the economic development of any country. In the case of the developing countries, the energy sector assumes a critical importance in view of the ever-increasing energy needs requiring huge investments to meet them.

A digital simulation model has been presented for locating the steady state stable brine cone position beneath partially penetrating wells tapping from the fresh water zone overlying a saline zone in an unconfined anisotropic aquifer. A graphical procedure developed by Morris Muskat has been converted into a numerical one and is used to successively approximate the brine cone position. The truncation in the fresh water zone both due to the brine cone and the depression in the water table are taken care of by repeated adjustment of the hydraulic conductances of the affected branches in the numerical model of the aquifer. An iterative version of the alternating direction implicit method has been used to solve the flow equations repeatedly till successively modified fresh water flow zones converge within a specified tolerance level. The results from the simulation model for a range of expected field conditions of aquifer, well and fluid density contrast have been presented in the form of graphs making use of appropriate non-dimensional parameters. These results can find applications in designing wells so that the discharge from those wells are limited to levels below which fresh water alone is drawn without any contamination by the underlying salt water.
