Current distribution and motor unit recruitment in multiplane FES
(1988)A multiplane 3-D thigh model is considered. The current densities in various planes are obtained using the Laplace equation. Electrodes are placed both in the transverse and longitudinal direction. A method that provides ... -
Evaluation of a comprehensive risk factor index for acute coronary insufficiency
(1988)Earlier risk assessment for acute coronary insufficiency has been done on the basis of logistic function and multiple regression analysis. Such an approach does not take into account the pathophysiological relationships ... -
Electrical effects on mammalian sperm
(1988)Experimental data show that under the influence of an electrical current or an electrical charge, sperm acrosomal regions swell, release enzymes and disintegrate. This effect can be mediated at low potential gradients. A ... -
New approach to haemoglobinometry based on reflectance photometry
(1988)A new approach to haemoglobinometry based on reflectance photometry using a pretreated cell strip is described. A disposable cell strip is designed to absorb a standardized volume of blood from a finger prick without any ... -
On-line diagnosis of problems in drip infusion system by impedance and flow measurement
(1988)During intravenous infusion, even though the limb is immobilized the needle often punctures the vein and fluid accumulates subcutaneously. The infusion rate is also affected by total or partial blockage of the needle. None ... -
Electrical pacing of the ampullary isthmic junction for contraception
(1988)Results are reported of a study of the effect of chronic long-term stimulation of the ampullary isthmic junction on tubal functions and fertility in rabbits. Preliminary experiments show that a 6-V, 48-Hz, 1-ms pulse ... -
Quantitative reflectance haemoglobinometry
(1992)Conventional haemoglobinometry based upon optical transmission characterisation involves volumetric measurements and chemical processing in liquid media, thus making the procedures cumbersome. Reflection measurements being ... -
An improved motorcycle helmet design for tropical climates
(1993)Approximately 20% of all fatal traffic crashes in India involve riders of motorized two-wheelers. Head protection of two-wheeler riders is therefore a very important issue. This paper reports the results of a survey of ... -
A new EEG signal processing technique for discrimination of eyes close and eyes open
(1995)Earlier difficulties have been observed in generating control sequences for prosthesis as well as other applications when using biological signals such as EEG. This paper deals with a new methodology of using EEG and ... -
Computer aided rehabilitation for the handicapped
(1995)Miniaturization in electronics and unlimited flexibility of computers has helped in providing a comprehensive support to the disabled for their independent living. Earlier difficulties in drawing hardware specifications ... -
Nonlinear visco-hyperelastic constitutive relation for brain tissue with parametric sensitivity study
(1995)Biological tissues are known to be hyperelastic with strong viscous properties. Constitutive equations employing Mooney and Hart-Smith strain energy functions have been developed approximating brain as a thick hollow ... -
A chemical cell to estimate quantitatively haemoglobin and glucose by reflectance photometry
(1995)Presents the estimation of two important biochemical parameters-haemoglobin and glucose, quantitatively by a single chemical cell. The chemical cell has been so designed to be made of layers of cellulose matrix containing ... -
Nutritional risk factors in carcinoma esophagus
(1995)A case control study was conducted on 75 patients with esophageal cancer and 75 normal healthy attendents of patients as controls to identify risk factors for esophageal cancer. Increased risk was associated with low intake ... -
Interplay of matrices in cartilage synovial fluid combine under moderate and high loadings
(1995)The interplay of the constituents of articular cartilage synovial fluid is examined from the biochemical and rheological study on bovine joint. Results show an inverse relationship between the changes in the hyaluronic ... -
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 ... -
Multiple DC field pulse mediated fusion of RBC with amnion
(1995)Cells tightly contacted to tissue surface by mechanical pressure or AC dielectrophoresis can be fused by electropulsing on to the tissue membrane. We report a multiple pulse electrofusion process to fuse uncontacted human ... -
Evanescent wave fibre optic sensor for detection of L. donovani specific antibodies in sera of kala azar patients
(1997)An easy-to-use technique for detection of antibodies specific for the parasite L. donovani in human serum sample has been developed. The method is based on an evanescent wave generated from a tapered configuration of ... -
Phase II clinical trial of a vas deferens injectable contraceptive for the male
(1997)Following up on an earlier clinical trial demonstrating the safety of an intra-vas deferens injection of a contraceptive drug named Risug, comprised of styrene maleic anhydride (SMA) in a solvent vehicle of dimethylsulphoxide ... -
Two-year clinical efficacy trial with dose variations of a vas deferens injectable contraceptive for the male
(1998)Contraceptive action of a single intra–vas deferens injection of a specific preparation of styrene maleic anhydride (SMA) dissolved in dimethyl sulphoxide, forming a drug given the name Risugt, has been demonstrated ... -
Reversibility with sodium bicarbonate of styrene maleic anhydride, an intravasal injectable contraceptive, in male rats
(1998)A copolymer of styrene and maleic anhydride (SMA) was dissolved in dimethyl sulphoxide (DMSO) and injected into the lumen of the vas deferens of rats. The polymer was retained in the lumen for a period of more than 90 ...
