A highly sensitive differential pulse polarographic (DPP) method has been developed for the determination of trace amounts of osmium, based on the catalytic effect of osmium (VIII) on the oxidation of pyrogallol red (PGR) ...

Laser fusion simulations are carried out for DT and D- He pellets by using a hydrodynamic code including heating from all charged reaction products and neutrons. It is shown that the inclusion of the side reactions and ...

The binding behavior of a competitive inhibitor, N-phenylbenzhydroxamic acid (BHA) against horseradish peroxidase (HRP) was studied in order to understand and predict the interaction mechanism of hydrogen donors with the ...

The main purpose of this paper is to establish a relation between universality of certain P-compactifications of a semitopological semigroup and their corresponding enveloping semigroups. In particular, we show that if ...

A totall of 500 Early Permian samples from the Chal-i-Sheh Formation in the Zagros Basin were examined palynollogically in order to determine the stratigraphical age of the formation and to assess the palaeogeopaphicd ...

3-Mercapto-1,2,4 benzotriazine (1) was methylated by methyl iodide in the presence of base to afford 1,2-dihydro-3-methyhercapto-1, 2,4 benzotriazine (2). The latter was reacted with hydrazine hydrate to give the ...

A general theoretical description of dual-beam photothermallensing spectroscopy is given. The results are valid for most general conditions, that is, for flowing as well as stationary media, for optically thick as well ...
