A pot experiment was performed to study the Cd-induced alterations in seed quality at maturity in two transgenic upland cotton cultivars, ZD-90 and SGK3, and the upland cotton standard line, TM-1. The results shown that Cd content in cotton kernels increased linearly with the elevation of Cd stress levels. SGK3 accumulated more Cd than others. Protein content in the kernels was increased under ...

When used in low concentration, formaldehyde increases the rate of autolytic disintegration of pneumococci whereas in large concentrations it completely inhibits autolysis and preserves both the morphological and staining characteristics of the cells. Pneumococci treated with large concentrations of formaldehyde, then washed free of the antiseptic and resuspended in physiological solutions, rap...

Objective: Diverse studies have demonstrated that no single method of dissolution testing is suitable for different types of suppository dosage forms by either current USP and Ph.Eur methodologies. The objective of the research work was to overcome the methodological problem and limitations by a novel modified basket method. Materials and Methods: USP dissolution apparatus-I was modified by pla...

E3d was )ess thermostable than E3c; E3d and E3c lost half of their original activities upon incubations for 30 min at 790C and 900C, respective]y. Heat treatment of E3d raised the fluorescence ;ntensities of Trp residue, intrinsic FAD, and extrinsic 8-anilinonaphthalene-1-sulfonate. E3d lost FAD, and inactive E3d polypeptides were aggregated. The sulfonate bound to the aggregate became notably ...

The purpose of this paper is to list and discuss briefly some of the causes of chemical and physico-chemical disintegration of concrete and to point out some methods that can be used to study these causes. In this paper a distinction is made between physico-chemical (or chemico-physical) and mechanical causes of failure. Processes involving changes in chemical composition (chemical reactions pr...
