Alkaloids were extracted by the method previously reported and separated into phenolic and non-phenolic fractions (1). Crystallization of dolichotheline was accomplished by treating the condensed non-phenolic fraction with benzeneacetone (1:l). The crystalline base (0.02% on the basis of dry weight) melted at 130-131", was homogeneous on TLC and gave the characteristic red color of nonsubstitut...

The formation of multi-soliton configurations in Bose-condensed alkali-metal atoms is analyzed by using the nonpolynomial Schordinger equation. A train of bright solitons is obtained from an axially homogeneous Bose-Einstein condensate by a sudden change of the scattering length from repulsive to attractive. We derive an analytical expression for the number of bright solitons generated by using...

Ph.D., F.R.I.C. (Pp. 214, 15s.). London: Bailli6re, Tindall & Cox, 1964. Ths small book replaces the popular "Aids to Organic Chemistry" by the same author. The thirty-eight chapters cover structural isomerism and stereoisomerism, the general properties of the main groups of organic compounds and a brief description of important heterocyclic and polycyclic substances. The general lay-out is exc...

In the present research work two aspects of ABO3 type perovskite has to be studied namely structural and mechanical. We have started our work by making an extensive survey of the literature regarding structral properties of ABO3 type perovskite. There has been found a number of approachces in order to understand structural properties of ABO3 type perovskite such as Experimental approaches, Comp...

The phenomenon of capillary condensation is studied through the weight change of condensed phase in an internally wetted porous pd catalyst pellet during the course of exothermic reacation of cyclohexane hydrogenation in a thermogravimetric analyzer (TGA). The direct measurement of condensed phase indicates that evaporation of condensed phase is confined to the macropores of catalyst pellet at ...

In eukaryotes, 45S rRNA genes are arranged in tandem arrays of repeat units, and not all copies are transcribed during mitosis. DNA methylation is considered to be an epigenetic marker for rDNA activation. Here, we established a clear and accurate karyogram for Jatropha curcas L. The chromosomal formula was found to be 2n=2x=22=12m+10 sm. We found that the 45S rDNA loci were located at the term...

the objective of this study was to determine the effect of irradiation of pomegranate seed (ps) on chemical composition, digestibility and kinetic of gas production. pomegranate seeds were exposed to gamma ray (gr) and electron beam (eb) at doses of 5, 10, 15 and 20 kgy. three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...

DNA damage induced via dissociative attachment by low-energy electrons (0 to 20 eV) is well studied in both gas and condensed phases. However, the reactivity of ultrashort-lived prehydrated electrons ([Formula: see text]) with DNA components in a biologically relevant environment has not been fully explored to date. The electron transfer processes of [Formula: see text] to the DNA nucleobases G...

Using the relativistic Hartree-Fock approximation, we calculate the rates of atomic ionization by absorption of axions of the energies up to 100 keVand for an arbitrary value of the axion mass. We present numerical results for atoms used in the low radioactive background searches of dark matter (e.g., Ar, Ge, and Xe), as well as an analytical formula which fits numerical calculations for the ab...
