Oscillator strengths and lifetimes of all energy levels of CuI, Agl and AuI were calculated using the Coulomb approximation (for The first time), and then compared with available data

Cyclohexylidine-ammonium-2-aminocyclohexyline-l-cyclohexee-l- dithiocarboxylate (CCCD) is employed for the gravimetric determination of Ni (II). In neutral or ammoniacal solutions, the metal forms a violet precipitate ...

Pb(OAc) /Cr0 combination was found to be able to oxidize methylene dioxide function in the presence of diphenylmethane moiety

2- Methylsulfonyl - 5- (1-methyl-5-nitro- 2 – imidazolyl ) 1,3,4 - thiadiazole ( 1 ) was prepared by twa independent routes.1) reaction of 1-methyl-2-formyl-5- nitroimidazole (3) with methyl hydrazinecarbodithioate ...

Different procedures for the syntheses of the title compounds were investigated. The best method for the preparation of the title compounds were the reaction of the readily available 2-formyL-1-methyl-5-nitroimidazole2 ...

A sufficient condition is obtained for two isometries to be unitarily equivalent. Also, a new class of M-hyponormal operator is constructed

Massive Zn-Cu-Fe sulfide deposits at the Garon Lake Mine occur in three sulfide lenses in a group of metamorphosed rhyolite crystal tuffs, metasediments and basalts. The major ore minerals are sphalerite, chalcopyrite, ...

Irradiation of &methyl spiro [2.5] oct-7-en-4-one through its singlet excited state resulted in the formation of 4-methyl spirO [2.5] oct-4-en -6-one. We have used the cyclopropyl moiety in the molecule as a probe to ...

Chronic urinary tract infections are often caused by antibiotic resistant bacteria. In some of these cases, prediction of the most effective antibiotic (s) may urgently be needed. This can not be achieved unless the ...

In this article we will use the redefined definition of a fuzzy subgroup as in [1], and will mainly prove that if G, G are two groups and f: G G' is an epirnorphism, then there is a bijection between the set of all ...

The present work comprises the synthesis of one series of diarylmethane dyes containing one or more terminal methoxy substituents together with a variable tertiary amino group. The electronic absorption spectra of the ...

Zeolites A, X and HS were synthesized from natural Iranian Kaolinite by alkaline fusion,,followed by refluxing the mixture. The transformation of zeolites X to HS and Y to P were studied at different time intervals by ...

An extract of henna (Lawsonia inermia) was found to be active in vitroagainst gram (+) and gram (-) bacteria including Bacillus anthracis, B.cereus, B. subtilis, Enterobacter aerugenes,Escherichia coli 0128-B7, E.coli ...
