Modern trends in the creation and development of corporate information systems (CIS) are largely determined by their consumer quality. A model building a system universal open architecture is presented. The possibility using CIS for managing production processes shoe organization demonstrated.

The title compound has been synthesized starting from cis- N- (a - methylacrylyl) -3-N- Phenylacetamido -4- styryl -2- azetidinone (1) [1].

In the vertebrate retina, the final step of visual chromophore production is the oxidation of 11-cis-retinol to 11-cis-retinal. This reaction is catalyzed by 11-cis-retinol dehydrogenases (11-cis-RDHs), prior to the chromophore rejoining with the visual pigment apo-proteins. The RDH5 gene encodes a dehydrogenase that is responsible for the majority of RDH activity. In humans, mutations in this ...

The ability to dynamically control chirality remains a grand challenge in chemistry. Although many molecules possess chiral isomers, lacking their isolation, for instance during photoisomerization, results racemic mixtures with suppressed enantiospecific properties. Here, we present nanoporous solid which and enantioselective enrichment is induced by circularly polarized light (CPL). material b...

This paper analyzes the complex characteristic of enterprise competitive intelligence system (CIS). Establishment of CIS of enterprise is an important approach to promote the research leve1 of enterprise CIS. All methods and techniques can be integrated from other science fields into CIS research through CIS. The author put up with the architecture of CIS, which includes fundamental architectur...

Diastereoisomeric mixtures of cis-uvariamicin I (15R,16R,19S,20S,36S and 15S,16S,19R,20R,36S) and cis-reticulatacin (17R,18R,21S,22S,36S and 17S,18S,21R,22R,36S) were synthesized to determine the stereochemistry of the natural products isolated from Annona muricata. It was not possible to resolve a mixture of the four synthetic isomers using chiral HPLC, but the mixed isomers could be distingui...
