Pools of salt water and puddles created by giant waves from the sea due to the tsunami that occurred on 26th December 2004 would facilitate increased breeding of brackish water malaria vector, Anopheles sundaicus. Land uplifts in North Andaman and subsidence in South Andaman have been reported and subsidence may lead to environmental disturbances and vector(More)
A finite-element stress-analysis method for the left ventricular chamber is presented. The formulation uses an axisymmetric thick-shell element of the isoparametic type with three nodes to accommodate the meridional curved surface. The analysis also takes into account different fibre orientations across the myocardial wall. The method is used to determine(More)
Vector mosquitoes of Japanese encephalitis (JE) breed mostly in rice fields, and human cases occur scattered over extended rural rice-growing areas. From this, one may surmise an ecological connection with the irrigation facilities and paddy cultivation. Furthermore, it has been hypothesized that a particular stage of paddy growth is a premonitory sign that(More)
An electric field is set-up in the human body by externally applied potential differences in biomedical research, medical diagnosis and therapy. It is important to know the electric-field distribution and current densities in different parts of the body from both the research and clinical points of view. In the present paper, the electric-field pattern is(More)
This paper deals with the monitoring of joint diseases status under the influence of high frequency electrical signals. The response of the system for applied electrical signal was acquired, processed and displayed using four surface electrodes, Bio signal amplifier, Analogue to digital converter and PIC microcontroller. The electrical property of the(More)

(e-mail: msingh@acer.iitm.ernet.in) tuitum and M. parafortuitum have three clusters of mycolic acid peaks. The majority of the test isolates were identified as M. terrae, which has only two clusters, similar to M. diernhoferi. The good(More)
