Room temperature solvent free aza-Michael reactions over nano-cage mesoporous materials
Kalita Pranjal, Pegu Choitayna Dev, Dutta Prantu , Baruah Pranjal K
| 2014
An efficient highly acidic three dimensional mesoporous aluminosilicate nano-cage material Al-KIT5, exhibited excellent catalytic activity in solvent free room temperature aza-Michael reactions of amines with ?, ?-unsaturated carbonyl compounds to produce ?-amino carbonyl compounds with 100% product selectivity in a short reaction time. The high acidity, 3D pores, and a huge space in the nano-cages materials make them attractive candidate for carrying out important organic reactions.
Road Map Towards Net Zero Energy Building
Sastry Minni
| 2014
To reduce the gap between demand and supply of energy of buildings in India, it is important that policies are framed to provide standards and road map for implementing net zero buildings in India.This can be achieved by methodologies that involve climate analysis, bioclimatic architectural design and selection of materials, innovative system design for air conditioning and lighting. The result of these methodologies would be reduction in energy demand which is met by renewable resources.
Resource Efficiency for Sustainability in Ferrous Foundry - A Case of Kolhapur MSME Cluster
Nand Gopal E, Ramesh D
| 2014
The Micro, Small and Medium Enterprises (MSME) play a vital role in the Indian economy. There are more than 4500 foundries in India and 80% of them are small-scale industries. The erratic global economic slowdown, has threatened the sustainability of MSME foundries. The paper emphasises on the importance of resource efficiency parameters for sustainability of a ferrous foundry.
Renewable Energy Programs for Rural Electrification: Experience and Lessons from India
Palit Debajit , Sarangi Gopal K
| 2014
Grid electrification has been the predominant mode for electrification covering almost 94.5% of the inhabited area in India. However, renewable energy based off-grid technologies have also been disseminated extensively in the country. This paper attempts to capture the development of off-grid rural electrification through renewable energy in India and analyses the experiences and lessons, which can contribute for the better program designing and policy making.
Renewable Energy based Mini-grids for Enhancing Electricity Access: Experiences and Lessons from India
Palit Debajit, Sarangi Gopal K
| 2014
Conventional grid extension has been the predominant mode of electrification in India. However, renewable energy based mini-grids have also been used for providing electricity access in remote areas, forested habitations, and islands. This paper, based on extensive literature review, interview with key stakeholders, and field visits to selected sites, captures the nuances of renewable energy based mini-grid developments in India.
Remembering the forest while viewing the trees: Evolutionary thinking in the teaching of molecular biology
Saraswati Sitaraman, Sitaraman Ramakrishnan
| 2014
Given the centrality of evolutionary theory to the study of biology, we present a strategy for reinforcing its importance by appropriately recontextualizing classic and well-known experiments that are not explicitly linked with evolution in conventional texts. This exercise gives students an appreciation of the applicability of the theory of evolution in diverse contexts, including those where it is not explicitly mentioned.
Regulated Marketing in India in the Period of Reforms: Redundant or Useful
Ghosh Nilabja , Vadivelu G Ananda
| 2014
Regulated marketing is only a transitory stage in the evolution of agricultural markets. With economic reforms, the role of government is desired to be curtailed and as a response, several models of marketing are found to be emerging at the all India level. Based on primary data and insights collected from different parts of the country we argue that it is imperative that regulated marketing survives and continue to function as of now but recognizing the importance of technology, freedom of choice and the advantages of shortened channels, some rethinking may be required.?
Reforming LPG and Kerosene Subsidies: Short-term priorities and long-term ambitions
Joshi Madhura, Ramakrishnan Anjali
| 2014
A detailed study on the impact of re-alignment of subsidies on fuels used by the masses revealed that the move did help in eliminating hoarding and black- marketing of the subsidised fuels, but it also brought out the level of dissatisfaction among the beneficiaries with regard to the scheme as a whole.
Rapid, efficient and high-performance protocol for Agrobacterium rhizogenes-mediated hairy root transformation of the common bean Phaseolus vulgaris
Khandual Sanghamitra , Reddy Pallavolu Maheswara
| 2014
A rapid, efficient and high-performance transformation protocol employing Agrobacterium rhizogenes was developed for the common bean Phaseolus vulgaris. In this study, we examined competencies of various protocols to induce and explants that respond to hairy root transformation in bean plants. Utilizing young seedlings with severed radicles/hypocotyls, we developed a highly efficient procedure for achieving hairy root transformation frequencies as high as 100% as visualized by GUS reporter gene expression system.
Random forest classification of urban landscape using Landsat archive and ancillary data: Combining seasonal maps with decision level fusion
Ghosh A, Sharma R, Joshi P K
| 2014
Mapping landscapes in a rapidly urbanizing region can contribute significantly to quantifying, monitoring and understanding the complex process of urbanization. However, mapping such urban areas is a challenging task due to issues of spatial heterogeneity and dynamic land use practices. In this study we propose an operational mapping algorithm using multi-season Landsat and ancillary data with minimum image pre-processing and limited training samples. The methodology was applied to produce a detailed land use land cover (LULC) map of National Capital Region of India.
