Crystallization plays an important role in separation and purification of the antibiotics. And it is also an indispensable step in preparation of pharmaceuticals with biological activities and specific crystal form. As the last step in purification, crystallization determines the puri‐ ty, crystal habit, granularity and its distribution as well as pharmacologic effect, biologic ac‐ tivity and p...
Fuzzy vectors were introduced as a description of imprecise quantities whose uncertainty originates from vagueness, not from a probabilistic model. Support functions are a classical tool for representation and computation with compact convex sets. The combination of these two techniques—support functions of fuzzy vectors—has been proposed by Puri and Ralescu. Independently, Bobylev proposed ano...
One of the numerical methods for solving linear Volterra integral equations is block-by-block method, which is explained in [L.M. Delves, J.L. Mohamed, Computational Methods for Integral Equations, Cambridge University Press, 1985; L.M. Delves, J. Walsh, Numerical Solution of Integral Equations, Oxford University Press, 1974] and [P.K. Kyte, P. Puri, Computational Methods for Linear Integral Eq...
In Puri town and district and throughout Orissa, cholera shows itself year after 37ear regularly over a defined area, and from this " infected focus" the disease invades the same bazaars and villages, leaving the greater part of the district untouched. The usual course of the disease is intimately connected with the pilgrimages. In Orissa, cholera is more 01 less endemic from January to August,...

Pectin methylesterase was extracted from potato tubers and partially purified in a single chromatographic step at large industrial scale. The preparation obtained in this way matched the temperature and pH profile of the species reported earlier by Puri et al. (Food Chemistry 8:203-213, 1982) and was enriched 23 times relative to the original potato tubers on a dry matter basis. Potato PME indu...
Thurid Gspann said: There appears to be a length issue when dealing with carbon nanotubes. On the one hand for most applications, mechanical as well as electrical, CNT ends represent the ultimate defect. In other words CNTs should be as long as possible. On the other hand, purication, solubilisation and separation processes either shorten CNTs or require them to be of a length usually less tha...
The gene for leader peptidase, termed lep, was mapped to the region between purI and nadB at min 54 to 55 on the Escherichia coli chromosome. Mapping involved (i) cloning the gene into the plasmid pBR322, (ii) transforming the plasmid into a polA strain where it cannot replicate autonomously, (iii) selecting by ampicillin resistance the rare cell in which the plasmid had recombined into the chr...
Mutations affecting the biosynthesis of quinolinic acid, a precursor of nicotinamide adenine dinucleotide (NAD) in Escherichia coli K-12, are either near min 17 (nadA mutants) or near min 49 on the chromosome. These nad mutants all exhibit a phenotypic requirement for NAD or one of its immediate precursors. The mutants with lesions near min 49 can be separated into two groups based on in vitro ...
