A theory-experiment comparison for the intensity and polarization dependence of spectrally resolved transient four-wave-mixing signals is presented for a ZnSe single quantum well. Results for high intensities deviate from a simple model based on the optical Bloch equations for a five-level...

Purpose – The purpose of this paper is to measure technical efficiencies, slacks and input/output targets for 50 large Indian pharmaceutical firms. Design/methodology/approach – The data are collected from Prowess of Centre for Monitoring of Indian Economy for the financial year 2010-2011....

Describes briefly the impact of Information Technology on collection management in libraries and also on the librarian's role. Discusses the factors affecting collection management in libraries and emphasizes the need for change in collection management policy. Provides information about the...

This paper applies data envelopment analysis (DEA) based Malmquist productivity index (MPI) approach to examine the total factor productivity (TFP) growth and its components of 50 private sector hospitals of India for the period 2004-2005 to 2009-2010. The study finds that on average, the TFP...

Natural changes in climate due to internal as well as external factors, like anthropogenic emission, fossil fuel combustion, transportation and heating which cause CO2 emissions is one of the major issues which causes global warming (increasing concentrations of greenhouse gases). The production...

Thermodynamic analysis for evaluating and improving coal gasification process efficiency requires estimation of enthalpy, entropy, and availability transformations in various process steps. A compilation of procedures and data relevant to coal gasification processes is presented for calculating...

Drying kinetics of materials may be described completely using their transport properties together with those of the drying medium. In the case of food drying, the drying rate constant ‘k’ was used instead of transport properties. The drying rate constant combines all the transport...

A naturally aspirated multi cylinder diesel genset (DG) was operated successfully with mixed fuels (fossil-diesel (FD), refined rice bran oil (RRBO) and producer gas from a wood gasifier). Performance of DG set in FD, dual fuel mode (FD+RRBO in different proportion and FD+producer gas) and mixed...

Purpose Energy supply delivered via various energy projects is an important aspect of energy security for India. Managing supply through various capacity additions for providing continuous electricity 24×7 by 2019 is a significant challenge for the country. In this context, there is a need to...

Purpose – The Indian garment industry has witnessed a significant change since the inception of the New Textile Policy 2000 that suggests removing the industry from the list of small‐scale industries with a view to improving its competitiveness in the global market. As productivity is the...
