    Description: Penaeus monodon, hitherto cultured in brackishwater, has been acclimatized to fresh water for culturing in fresh water system. One hundred juveniles of P. monodon measuring in an average 27.7 mm were procured from the coastal lowlying areas near Kakinada in Andhra Pradesh and were used to conduct an experiment on acclimatization. High percentage of survival (96.0%) was observed when the water salinity was lowered gradually at the rate of 10% per day for the first 2 days, 5% per day during the next 2 days and later at the rate of 1% per day.

    Nucleotide sequence of the first cosmid from the Mycobacterium leprae genome project: structure and function of the Rif-Str regions (1993)

    Notes: The nucleotide sequence of cosmid B1790, carrying the Rif-Str regions of the Mycobacterium leprae chromosome, has been determined. Twelve open reading frames were identified in the 36716bp sequence, representing 40% of the coding capacity. Five ribosomal proteins, two elongation factors and the β and β'subunits of RNA polymerase have been characterized and two novel genes were found. One of these encodes a member of the so-called ABC family of ATP-binding proteins while the other appears to encode an enzyme involved in repairing genomic lesions caused by free radicals. This finding may well be significant as M. leprae, an intracellular pathogen, lives within macrophages.

    Volume diffusion of I− anions in near surface region of copper (1991)

    Notes: Abstract Volume diffusion of I− anions in the near surface region of copper has been studied by radiotracer technique. The diffusion coefficients were determined for different I− coverages on copper employing the Gruzin method of measuring the residual activity. Diffusion annealing was carried out between 303 and 673 K. The distribution of the I− species in the diffusion-annealed sample was monitored by noting the residual activity of the specimen upon subjecting it to successive acid-etchings. The simultaneous evaporation losses from the I− deposit are reduced by securely holding the sample coupon in between two blank copper coupons using a metal clip.

    Volume diffusion of I− anions in near surface region of silver (1988)

    Notes: Abstract Volume diffusion coefficients of I− anions in the near surface region of silver have been determined using131I. The distribution of the labelled ions with depth is determined by acid etching and counting the residual activity. The coefficient of diffusion is determined for surface layers of three different thicknesses over the temperature range 373–823 K. The mechanism proposed assumes the dissociation of Ag+I− in surface layer and the diffusion of I− into the interstitial free space immediately beneath the surface. This process is found to be accompanied by a small negative entropy change.
