Efficacy of two dominant marker systems, ISSR and TE-AFLP for assessment of genetic diversity in biodiesel species Pongamia pinnata
Sharma Shyam Sunder, Aadil Keshaw, Negi Madan Singh, Tripathi Shashi Bhushan
| 2014
The extent of genetic diversity was assessed in 12 Pongamia accessions from different regions of Delhi and surrounding areas using two dominant markers,namely ISSR and three endonuclease AFLP (TEAFLP).Five ISSR primers and two TE-AFLP primer combinations generated a total of 12 and 48 polymorphic bands respectively. The Jaccard's dissimilarity coefficient ranged from 0 to 0.90 for ISSR and from 0 to 0.67 for TE-AFLP markers. The polymorphic information content of both markers was equal.
Effects of organic nitrification inhibitors on methane and nitrous oxide emission from tropical rice paddy
Datta Arindam, Adhya T K
| 2014
We have studied the effects of application of different nitrification inhibitors on methane (CH4) and nitrous oxide (N2O) emissions from rice paddy and associated soil chemical and biological dynamics during wet and dry seasons of rice crop in a tropical climate of eastern India. The experiment consisted of four treatments viz. (i) Prilled urea amended control (ii) urea ? Dicyandiamide (DCD), (iii) urea ? Nimin and (iv) urea ? Karanjin. CH4 emission was significantly higher from the DCD (372.36 kg ha1) and Karanjin (153.07 kg ha1) applied plots during the wet and dry season, respectively.
Effect of salts (NaCl and Na2CO3) on callus and suspension culture of Stevia rebaudiana for steviol glycoside production

| 2014
Steviol glycosides are natural non-caloric sweeteners which are extracted from the leaves of Stevia rebaudiana plant. Present study deals the effect of salts (NaCl and Na2CO3) on callus and suspension culture of Stevia plant for steviol glycoside (SGs) production.
Effect of nitrogen concentration on lipid productivity and fatty acid composition of Monoraphidium sp
Dhup Saumya and Dhawan Vibha
| 2014
Green algae, Monoraphidium sp. T4X, was isolated locally, in New Delhi, India and identified as a potential source of biofuel. The study focuses on the effect of nutritional amendments and their uptake rates with respect to growth and change in fatty acid composition of the species. The lipid productivity and fatty acid profile were investigated and compared under six different nitrogen concentrations.
Effect of construction materials on embodied energy and cost of buildings-A case study of residential houses in India up to 60 m2 of plinth area
Bansal D, Singh R, Sawhney R L
| 2014
Worldwide buildings consume annually about 30-40% of primary energy in construction, operation and maintenance. An enormous part of this energy is consumed in construction activities alone. Nearly two million residential buildings for economic weaker section alone, are required to be built annually in India, apart from offices, commercial, public and industrial buildings. Use of low embodied energy and cost effective building materials, in the building construction, can significantly reduce the overall energy consumption and thus eventually minimize energy footprint of buildings.
Ecosystem services and forest fires in India — Context and policy implications from a case study in Andhra Pradesh
Schmerbeck Joachim M, Kohli A, Seeland K
| 2014
Tropical landscapes are often burned by forest dwellers to obtain certain ecosystem services (ES).We analyze the importance of ES derived with the help of fires froma tropical dry forest in Andhra Pradesh, India, and conclude that regular burning of the forest is crucial for local livelihoods. We highlight the importance of “fire-driven ecosystem services (FDES)” through investigating 557 rural households' livelihood spread across 14 villages in the Chittoor District of Andhra Pradesh.

Abstract Vegetable wastes (VW) and food wastes (FW) are generated in large quantities by municipal markets,restaurants and hotels. Waste slurries (250 ml) in 300 ml BOD bottles, containing 3, 5 and 7 % total solids (TS) were hydrolyzed with bacterial mixtures composed of: Bacillus, Acinetobacter, Exiguobacterium, Pseudomonas, Stenotrophomonas and Sphingobacterium species. Each of these bacteria had high activities for the hydrolytic enzymes: amylase, protease and lipase. Hydrolysate of biowaste slurries were subjected to defined mixture of H2 producers and culture enriched for methanogens.
Do free trade agreements promote intra-industry trade? The case of India and its FTAs
Ramakrishnan Anjali, Varma Poornima
| 2014
The paper examines the role of free trade agreements (FTAs) in promoting intra-industry trade (IIT) between India and its selected FTAs - Association of South East Asian Nations (ASEAN), South Asian Free Trade Agreement (SAFTA) and Sri Lanka. IIT is evident for India's trade with Sri Lanka and Singapore whereas the same is low for other countries. Even the observed IIT is mostly in the form of vertical IIT (VIIT). The results based on fixed effects model using gravity equation shows that the FTAs have a significant impact in promoting IIT.
Disease burden due to biomass cooking-fuel-related household air pollution among women in India
Sehgal Meena, Rizwan Suliankatchi Abdulkader, Krishnan Anand
| 2014
Household air pollution (HAP) due to biomass cooking fuel use is an important risk factor for a range of diseases, especially among adult women who are primary cooks, in India. About 80% of rural households in India use biomass fuel for cooking. The aim of this study is to estimate the attributable cases (AC) for four major diseases/conditions associated with biomass cooking fuel use among adult Indian women.

A network of air quality and weather monitoring stations was set-up across Delhi, India, under theSystem of Air quality Forecasting And Research (SAFAR) project. The objective of this network was toenable better understanding of air quality in terms of atmospheric chemistry, emissions and forecastingin Delhi, one of the largest metropolises in the world. In this study, we focus on the O3-NO-NO2-triad. Photo Stationary State (PSS), and investigate site-specific deviations in the Leighton Ratio (F) during ashort period in 2012 (1e31 December).
