The distribution of endogenous beta-galactoside-specific lectin, fibronectin, type I and III collagens was studied by the indirect immunofluorescence method during the formation of dermal condensation in the feathered region (dorsal skin) of a chick embryo. Endogenous beta-galactoside specific lectin was concentrated in the condensed dermal region, coinciding with the formation of condensation ...

A convenient, efficient and practical procedure for the synthesis of 1-amidoalkyl 2-naphthols is described by condensation of aromatic aldehydes with amides and 2-naphthol in the presence of P2O5/SiO2 as an efficient catalyst. Moreover, in the present of this catalyst, the synthesis of 14-aryl or alkyl-14H-dibenzo[a,j]xanthenes is studied by co...

an efficient method has been developed for the catalysis of condensation of 1,2-phenylenediamines and 2-aminothiophenoles with different aldehydes into their corresponding 2-aryl-1h-benzimidazoles and 2-aryl-1h-benzothiazoles under mild condition. in this method, trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane (dhpdmdo)/hoac/ki system was used as a novel and effective oxidant in water at roo...

For solving the eigenvalue problem of a structural system having a large number of degrees of freedom the authors introduced in 6] the improved condensation method using the Rayleigh functional of the exactly condensed nonlinear eigenvalue problem. In this paper we discuss the implementation of the method for substructured problems on a distributed memory MIMD Computer. Examples are presented w...
