GPS and GPRS Based Telemonitoring System for Emergency Patient Transportation.

Telemonitoring during the golden hour of patient transportation helps to improve medical care. Presently there are different physiological data acquisition and transmission systems using cellular network and radio communication links. Location monitoring systems and video transmission systems are also commercially available.

Dry ashing of organic rich matrices with palladium for the determination of arsenic using inductively coupled plasma-mass spectrometry.

A dry ashing procedure is developed for the determination of As in organic rich matrices such as wheat flour, lichen and tobacco leaves. The volatility of As during dry ashing is avoided by the addition of palladium nitrate [Pd(NO(3))(2)]. The recovery of both As(III) and As(V) is found to be near quantitative.

On-line preconcentration and recovery of palladium from waters using polyaniline (PANI) loaded in mini-column and determination by ICP-MS; elimination of spectral interferences.

The applicability of polyaniline (PANI) for the on-line preconcentration and recovery of palladium from various water samples has been investigated. Batch experiments were performed to optimize conditions such as pH and contact time to achieve quantitative separation of Pd spiked at high (microg ml(-1)) and low levels (ng ml(-1)). During all the steps of the removal process, it was found that Pd was selectively removed by PANI even in the presence of various ions.

Determination of trace impurities in chromium matrices after separation from Cr(III) using the oxalate form of anion exchanger.

A method has been developed for the separation and determination of a set of 11 impurities from chromium matrices using oxalate form of Amberlite IRA 93. Due to slower kinetics of formation of the anionic complex, Cr(III) passed in the effluent while impurities forming strong complexes rapidly are retained on the exchanger. The adsorption of impurities of interest is found to be uniform in pH range 2-6.

Biosynthesis of rifamycin SV by Amycolatopsis mediterranei MTCC17 in solid cultures.

Studies were performed on the production of rifamycin SV, an ansamycin compound, extensively used for curing tuberculosis, leprosy and several other mycobacterial infections, using a strain of Amycolatopsis mediterranei MTCC17 in solid cultures. Wheat bran was employed as a solid substrate. The culture produced 4 g of rifamycin SV/kg of substrate.
