Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 (0≤x≤1): synthesis, structure and dielectric properties
(2002)Oxides belonging to the families Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 were synthesized by the solid state reaction route. Sintering temperatures of 1300°C led to oxides with disordered (cubic) perovskite structure. However, ... -
Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9: synthesis, structural and dielectric studies
(2000)Oxides of the families Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 were obtained by the solid state reaction route at 1573 K and were found to crystallize in the disordered (cubic) perovskite structure. In Ba3ZnTa2−xNbxO9 and ... -
Barriers to dissemination of renewable energy technologies for cooking
(1995)A preliminary effort to identify the barriers to dissemination of renewable energy technologies in developing countries has been made. -
Behaviour of equipment mounted over a torsionally coupled structure with sliding support
(2000)Behaviour of a light equipment system mounted over a torsionally coupled and sliding primary system, is studied under bidirectional ground excitation. A fictitious spring model is considered in the analysis to deal with ... -
Bending induced phase shifts in arbitrarily bent rectangular-core dual-mode waveguides
(1996)We examine the variation of the effective indexes of the two modes of an arbitrarily bent dual-mode rectangular-core waveguide. We find that under the large bending radius approximation, which is indeed the practical case ... -
Bengali alpha-numeric character recognition using curvature features
(1993)This paper is concerned with recognition of hand-written and/or printed multifont alpha-numeric Bengali characters. It is assumed that characters are present in an isolated fashion. In the present work characters have been ... -
Benzoquinone modified electrode for sensing NADH and ascorbic acid
(1998)A benzoquinone modified basal plane pyrolytic graphite electrode shows electrocatalytic activity for the oxidation of NADH and ascorbic acid in phosphate buffer (pH 7.3). The modified electrode shows a linear variation of ... -
BER analysis of a set of TCM schemes for reducing cochannel interference in cellular mobile communication
(2000)Scarcity of the frequency band is acting as a bottleneck to the tremendous advancement in the field of mobile communication. Nowadays cellular technology is being invariably employed in mobile communication to maximize the ... -
Bhopal gas accident: a numerical simulation of the gas dispersion event
(1997)An account of the Bhopal Methyl Isocyanate (MIC) gas accident is given. A numerical modelling approach is presented that provides the prevailing flow and dispersion at the time of the infamous gas accident. The meteorological ... -
Bhopal gas leak: A numerical simulation of episodic dispersion
(1995)A mesoscale meteorological model coupled with a Lagrangmn particle dispersion (LPD) model was used to simulate the Bhopal methyl isocyanate (MIC) gas leak. A simple two layer K-closure version of the Pielke primitive ... -
Bias-induced changes in carrier type of Pb(1−x)Fe(x)S nanocrystalline solution grown thin films
(2002)Change of majority carrier type was achieved in nanocrystalline Pb(1−x)Fe(x)S thin films by applying a DC-bias on the substrate during their growth by solution growth technique. Critical control of biasing and pH of the ... -
Bidirectional ring-based termination detection algorithms for distributed computations
(1989)An interesting and difficult problem in the area of distributed problem solving is that of detecting the termination of distributed programs soon after their assigned task is over. In a distributed environment, processes ... -
Binary classification by SVM based tree type neural networks
(2002)A technique for building a multilayer perceptron classifier network is presented. Initially, a single perceptron tries to correctly classify as many samples as possible. Misclassified samples are taken care of by adding ... -
Biochemical kinetics in articular cartilage and synovial fluid
(1995)The compressive load bearing properties of articular cartilage depend on the cartilage-synovial fluid interaction. In freshly slaughtered bovine knee joints, proteoglycan and uronic acid contents in cartilage and synovial ... -
Bioconversion in an aqueous two-phase system using a smart biocatalyst: casein hydrolysis by a α-chymotrypsin derivative
(2003)Casein hydrolysis was carried out in PEG–dextran two-phase system by using α-chymotrypsin immobilized on a water soluble polymer Eudragit S-100. This biocatalyst along with the substrate casein was predominantly found to ... -
Biodesulphurization of coal: effect of pulse feeding and leachate recycle
(2001)Biodesulphurization of coal was carried out under four modes of operation namely: conventional batch, constant volume pulse feeding (CVPF), increasing volume pulse feeding (IVPF) and leachate recycle. The effects of different ... -
Biodesulphurization of Indian (Assam) coal using thiobacillus ferrooxidans (ATCC 13984)
(2000)The pyritic sulphur removal from coal and pyrite by Thiobacillus ferrooxidans was studied in a batch reactor. Microbial oxidation of ferrous iron to the ferric form, the central step in the biodesulphurization process was ... -
Biofuel mix for cooking in rural areas:implications for financial viability of improved cookstove
(Elsevier Science, 1996)An attempt to study the financial implications of replacing a traditional biofuel cookstove with an improved one has been made. The role of several factors influencing the cost of an improved cookstove has been discussed. ... -
Biogas scrubbing, compression and storage: perspective and prospectus in Indian context
(2005)Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapours. Presently, it can be used only at ... -
