Free Odd Periodic Actions on the Solid Klein Bottle
The cyclic actions of odd period and empty fixed point set are studied on the solid Klein Bottle K. It is shown that up to weak equivalence there is only one such action.
Mathematical Analysis of a Vibrating Rigid Water Tank
The hydrodynamic pressure distribution on the wall of a vibrating water tank is traditionally expressed as a summation of two components; an impulsive component and a convective one obtained by separating the potential ...
Kinetics and Mechanism of the Hydrolysis of Benzylidene Benzoylhyd - Razone Derivatives
The kinetics and mechanism of hydrolysis of a series of substituted benzylidene benzoylhydrazones (X — BBH) have been studied at five different temperatures in the range 25 — 45°c by U. V. -visible spectrophotometry. The ...
Short Communication: Synthesis of 2-(Chiral Alkyl) Oxazolines
A modified Vorbruggen method has been used to prepare 2 - ( chiral alkyl ) oxazoline with phenyl and aminoacid residue. Other methods of preparation have been tested.
Short Communication: Addition of Bis (methylthio) acetylene to Nitrilium Salts
Azaallenium salt 7 was isolated at low temperature by the addition of bis (methylthio) acetylene to nitrilium salts. The isolated azaallenium salt 7 was rearranged to afford the 1:1 heterocyclic adduct 8. A detailed mechanism ...
Short Communication: Solvent Effects on ρ Values of the Hammett Equation for the Hydrolysis of Benzylidene Benzoylhydrazones
The effect of solvents on ρ values of the Hammett equation which characterizes the hydrolysis of Benzylidene Benzoylhydrazone (BBH) and its derivatives (m—NO2 m—CH3, m—OCH3 and m—Cl), have been studied with four solvents ...
