tected, as it were, from another crossing over. This relation is illustrated in the diagram (fig. 7). If crossing over occurs at some point between two pairs of factors a and b indicated on the diagram, the next crossing over point of the chromosome would, if it occurred at all, lie at some distance away, rather than near by. This possibility can be tested in a case where several known points a...
متن کاملStudies on new antibiotics SF2415. I. Taxonomy, fermentation, isolation, physico-chemical properties and biological activities.
A new species of Streptomyces is described for which the name Streptomyces aculeolatus is proposed. The organism produces new antibiotics SF2415A1, A2, A3, B1, B2 and B3 active against Gram-positive bacteria. Empirical molecular formulae of the antibiotics SF2415A1, A2, A3, B1, B2 and B3 were determined to be C26H31N2O5Cl, C26H30N2O5, C26H30N2O5Cl2, C26H33O5Cl, C26H32O5 and C26H32O5Cl2, respect...
متن کاملPhysico-Chemical Disintegration of Concrete
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...
متن کاملPhysico-chemical Studies on Stability of Clopidogrel Tablet Formulations
Clopidogrel bisulphate (anti-coagulant drug) is an enantio-selective chrial drug and needs to be monitored for the active form in tablet formulation. Hence, a stable tablet formulation was developed for clopidogrel using two different disintegrants of LHPC (to match as closely as possible to innovator tablet) and PVPP XL. Tablets were evaluated for stability analysis using validated analytical ...
متن کاملThe Studies on the Physico-Chemical and Organoleptic Characteristic
A highly significant effect (p<0.05) of storage period on physico-chemical characteristics and sensory parameters of Apricot fruit produced in Rawalakot areas of Azad Jammu and Kashmir was investigated at ambient temperature (Relative humidity 60-63% and temperature 28-30 C). The physicoo chemical characteristics such as weight loss, total soluble solids, titratable acidity, ascorbic acid and s...
