| 2014
Persistent organic pollutants (POPs) have been used in a wide range of agricultural and industrial commodities,resulting in vigorous deterioration of environment and human health. A number of studies on the occurrence of POPs confirmtheir presence in various environmental compartments and human body. In order to dealwith this global concern, India has recently prepared the National Implementation Plan (NIP) of the Stockholm Convention.
Enrichment and optimization of anaerobic bacterial mixed culture for conversion of syngas to ethanol
Singla Ashish, Verma Dipti, Lal Banwari, Sarma Priyangshu M
| 2014
The main aim of the present study was to enrich anaerobic mixed bacterial culture capable of producing ethanol from synthesis gas fermentation. Screening of thirteen anaerobic strains together with enrichment protocol helped to develop an efficient mixed culture capable of utilizing syngas for ethanol production. Physiological and operational parameters were optimized for enhanced ethanol production. The optimized value of operational parameters i.e. initial media pH, incubation temperature, initial syngas pressure, and agitation speed were 6.0±0.1, 37°C, 2kgcm-2 and 100rpm respectively.

Sharma Reeta and Ganguly Shantanu
| 2014
This chapter explore how TERI, being a research organization, emphasizes knowledge creation and global dissemination of its research on sustainable development. Knowledge Management division was created to meet the challenges of the knowledge acquisition, management, and outreach demands of the research community.
Energy demand and CO2 emissions from urban on-road transport in Delhi: current and future projections under various policy measures
Aggarwal Preeti, Suresh Jain
| 2014
This work presents an analysis of road transportation in Delhi region with focus on energy demand and carbon dioxide (CO2) emissions. The study has considered five scenarios for the year 2021; one business as usual, and four future alternative scenarios, with 2007 as the reference year. The alternative scenarios have been developed by considering the introduction of six policy interventions, namely; construction of integrated mass rapid transit system (IMRTS), fixed bus speed, hike in parking fees, fuel efficiency,stringent emission norms, and increase in the occupancy of private vehicles.
Energy conservation measures in foundries
Pal Prosanto, Vasudevan N
| 2014
Metal casting is one of the most energy intensive sectors in India. The Bureau of Energy Efficiency (BEE) in India has listed metal casting industry to be among the top ten major industrial sectors in India in terms of greenhouse reduction potential. This paper talks about some common ways of improving the energy performance of Indian foundry units.
Endophytic Fungi for Stress Tolerance
Kaushik Nutan, Kumar Vikram
| 2014
Abiotic stress can be defined as the deleterious effects of non-living factors on living organisms in specific environments. The four major abiotic stresses that plants face are salinity, drought, temperature, and heavy metals. Although plants have complex and dynamic systems to respond to stress stimuli, abiotic stress is the most harmful factor concerning the growth and productivity of crops worldwide. Research has also shown that abiotic stresses are at their most harmful when they occur together, in combinations of abiotic stress factors.
ELECTRIFYING REMOTE AREAS: Innovations by OASYS South Asia Project
Palit Debajit, Sharma K Rahul
| 2014
The issue of electrifying inaccessible areas is the need of the hour today. To address this problem, various efforts have been made by different authorities. In this article,author describe an innovative effort of the OASYS South Asia Project to electrify remotely-located villages in India.
Efficacy of two dominant marker systems, ISSR and TE-AFLP for assessment of genetic diversity in biodiesel species Pongamia pinnata

| 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
Gupta Pratibha, Sharma Satyabati, Saxena Sanjay
| 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.
