Government of India had proposed to deployment of 40,000 MW of grid-connected rooftop solar power projects by the year 2021-22 under the National Solar Mission. Detailed review of various policy and guidelines developed for two major schemes such as off-grid and on-grid connected systems revealed that utility companies offered different types of cost effective tariff to facilitate quick start-up, implementation and encourage participation from stakeholders.

The influence of polarized electrodes on the methane production, which depends on the sludge concentration,
was investigated in upflow anaerobic bioelectrochemical (UABE) reactor. When the polarized
electrode was placed in the bottom zone with a high sludge concentration, the methane production was
5.34 L/L.d, which was 53% higher than upflow anaerobic sludge blanket (UASB) reactor. However, the
methane production was reduced to 4.34 L/L.d by placing the electrode in the upper zone of the UABE

Harmful algal blooms (HABs) are increasingly attracting attention all over the world. A diverse set of algal species including diatoms, flagellates, chrysophytes and dinoflagellates can cause harmful blooms, and many produce toxins that harm other organisms and human health. Intensive cyanobacterial blooms, in particular, have been associated with high costs for society due to their potential toxicity. Algal blooms can produce different toxins. These toxins present a long-standing threat to human and environmental health.

Construction sector accounts for about 25% of the carbon emissions in India. With constant increase in the rate of construction, it is important that the sector identifies and applies sustainable construction and production practices. The sustainability index (SI) of building materials created as part of the study in the Himalayan region of South Asia will help create low-cost, climate resilient structures based on local climate and available resources. This implies customization as per regional needs when scaling up in other topographies.

Children in government schools in Karnataka, India are provided cooked mid-day meals under the 'Akshara Dasoha' scheme. The aim of this initiative is to provide a nutritious meal to school children (who mostly hail from the lower economic strata) to enhance their nutritional status and as an incentive to minimize dropouts. However, cooking these meals have numerous bottlenecks including irregular supply of cooking fuel i.e.

Spatial and temporal variability of rainfall over different seasons influence physical, social and economic parameters. Pre-monsoon (March, April and May - MAM) rainfall over the country is highly variable. Since heat lows and convective rainfall in MAM have an impact on the intensity of the ensuing monsoons, hence the pre-monsoon period was chosen for the study. The pre-whitened Mann Kendall test was used to explore presence of rainfall trend during MAM. The results indicate presence of significant (at 10% level) increasing trend in two stations (Ajmer, Bikaner).
Transition of Digital library in a web enabled environment: from Semantic to Social Semantic Digital library
Alam Nihal, Karmakar Ranjan
Library is a primary source of information throughout the history of mankind and is present in our societies in different forms. Notably, the traditional digital libraries have taken the shape of semantic digital libraries, which gives a more meaningful search and can be accessible anywhere at any point of time. Now it is time to re-examine the role of digital libraries within a new paradigm of library service. This paper will identify how it influences professional’s information needs and use of resources to meet those needs by different forms of Digital libraries in a web environment.

The Indian Ministry of New and Renewable Energy (MNRE) launched the Village Energy Security Programme (VESP) in 2004 but discontinued it during the 12th Five Year Plan, starting in 2012, after a series of unexpected challenges. Planners structured the program so that a village energy committee (VEC) ran a decentralized village program involving biomass gasifiers, straight vegetable oil (SVO) systems, biogas plants, and improved cookstoves. This suite of technologies was intended to produce electricity and thermal energy to meet the total energy requirements of rural communities.
The Evaluation of Two-stage Chemical Fractionation for the Enhanced Enzymatic Saccharification of Cellulose in Rice Straw
Banerji A, Kurian J, Kishore V V N and Balakrishnan M
Rice straw, an agro-residue, can be utilized as a renewable resource for the production of fuel and chemicals. This study evaluates a two-stage chemical pretreatment (dilute acid hydrolysis followed by alkaline-peroxide delignification) for fractionation and enhancing the enzymatic saccharification of the rice straw cellulose to produce fermentable sugars. The process led to 100% hemicellulose dissolution and resulted in a solid residue with ~95% pure cellulose. Enzymatic saccharification of this cellulose liberates 70% more reducing sugars compared to other single-step pretreatment methods.
