The concentration of KOH solution used for PH adjustment during synthesis was 0.1 N. Yield of about 68% was obtained. The complex, when viewed under ordinary light looks pinkish and under ultraviolet radiation it emits intense red light. Fig. 2(a–c) shows three dimensional structure of ...

Daher kann man von einer Progression von einer eher deterministischen zu einer emergenten indeterministischeren Kulturkonzeption sprechen und das fünfdimensionale Kulturmodell Hofstedes dem Determinismus, das siebendimensionale Kulturmodell Trompenaars und Hampden-Turners hingegen dem Übergang vom ...
The present study of AlnSenclusters (n = 1–5) has been performed using density functional theory. The ground-state structures of these clusters along with low-lying isomers are explored. The stabilities of clusters are analysed by calculating their binding energy per atom and dissociation en...

We construct an (mathcal{N}=2) supersymmetric sigma model on the cotangent bundle over the Hermitian symmetric space E 7 /(E 6 脳U(1)) in the projective superspace formalism, which is a manifest (mathcal{N}=2) off-shell superfield formulation in four-dimensional spacetime. To obtain ...
Polyester resins on the basis of hydroxyl groups-containing prepolymers from olefinically unsaturated monomers are prepared by (1) polymerizing a mixture of (a) 60 to 90% by weight styrol or a styrol derivate having the general formula (I), in which R, R and R stand for hydrogen, methyl...
