Bioconversion of municipal solid waste and analysis of its physico chemical parameters

3

The compost products are useful in increasing soil fertility and decrease dumped municipal solid waste. Composting is accepted because it is economically and environmentally a safe method. Fungi are used for proper recycling of wastes. During the process of composting many physical parameters like pH, moisture content, Ash, weight loss increased.

Phytoresources of Satpura region of Chhindwara district Madhya Pradesh: An ethno-medicinal case study for antimalarials

3

Ethno medicinal survey was conducted in Satpura region with special reference to Chhindwara district of Madhya Pradesh. This district is a forest district,Chhindwara district, has acquired great importance because of its scenic beauty. Patalkot is a lovely landscape located at a depth of 1200-1500 feet in a valley, inhabited by Gonds, Bharia tribes who are entirely dependent on forest for medication. Information on 15 plant species belong to 15 genera and 14 families which are traditionally used as medicine to cure malaria was collected.

Publication Date: 
01/07/2012

The state of knowledge and outstanding issues with respect to the global mean energy budget of planet Earth are described, along with the ability to track changes over time. Best estimates of the main energy components involved in radiative transfer and energy flows through the climate system do not satisfy physical constraints for conservation of energy without adjustments. The main issues relate to the downwelling longwave (LW) radiation and the hydrological cycle, and thus the surface evaporative cooling.

Publication Date: 
01/07/2012

Waterlogging and secondary salinisation have become serious problems in canal irrigated areas of arid and semi-arid regions. This study examined hydrology and estimated the seasonal net groundwater recharge of an irrigated semi-arid region located in the Haryana State of India where about 500 000 ha area are waterlogged and unproductive, and the size of the waterlogged area is increasing, causing a threat to agricultural sustainability.

Technology progress - Impressive for PV, below par for thermal

9

A considerable amount of time and monetary resources have been spent by corporations, governments, researchers, scientists and engineers to promote the use of solar power based generation systems. Though innovative government policies are mainly credited for reducing solar power costs from Rs 17 per kWh in 2006007 to Rs 8-Rs 9 per kWh currently and increasing the grid connected capacity to around 1,000 MW, advancements in research and development (R&D) have also played an important role.

JNNSM gains - Learning from Phase I

9

By mid-June 2012, India's total grid-connected solar capacity reached 1,025 MW. Though states such as Gujarat have led the race in harnessing the country's solar potential by formulating policies that benefit developers, it is the Jawaharlal Nehru National Solar Mission (JNNSM) that has attracted established global and domestic developers to the Indian solar power sector.

Publication Date: 
01/07/2012

Companies involved in the development energy generation technologies need to proactively and responsibly address issues related to the environmental and socio-economic impact of these technologies. Managing solar photovoltaic (PV) panels after their useful life is a crucial part of responsible life-cycle management. This not only minimises the potential negative impact at the last stage of a technology's life cycle, but also allows re-utilisation of valuable materials for new products.

Steady progress - SHP exceeds Eleventh Plan target

9

Small-hydro power (SHP) is one of the growing segments in the renewable energy space. Unlike the state driven growth witnessed in the solar and wind segments, there has been a steady increase in SHP capacity over the past few years. The segment witnessed a capacity addition of 1,419 MW during the Eleventh Plan period, slightly higher than the target of 1.400 MW. As per the Ministry of New and Renewable Energy (MNRE), its total installed capacity stands at 3,395 MW.
