Conceptualizing Architectures for E-Business Systems

E-Business (E-Commerce) infrastructure requires organizations and their IT systems to be flexible and adaptive to changes in the dynamic business environment. Component-based development is seen to be the solution for rapidly creating modifiable and maintainable e- Business systems. Organizations have attempted to strategically align their IT and organizational goals in developing mission-critical e-Business systems. In this research we propose a architecture for designing such systems based on the notion of business capabilities and technology capabilities. This tiered architecture provides a formal framework for understanding the cohesive relationships between IT and business capabilities in organizations. It allows for rapid “what-if” analysis for managing IT investments and offers the flexibility needed to manage changes in designing and developing information systems for e-Business. The architecture supports the packaging of existing legacy systems and links them to the e-Business systems to create outward facing mission-critical information systems demanded by the e-Business infrastructure

Studies in sesquiterpenes-LII: Isohimachalone: a constituent of the essential oil from wood of Cedrus deodara loud

Isolation and structure elucidation of a new bicyclic sesquiterpene of a new carbo-skeleton, from the essential oil from the wood of Credrus deodara loud., is reported. The structure rests on a direct correlation with β-himachalene

Studies in sesquiterpenes-LIV: Oxidohimachalene, a novel sesquiterpenoid from the wood of Cedrus deodara loud

Isolation and structure elucidation of oxidohimachalene, a minor constituent of the essential oil of Cedrus deodara Loud., is described. A biomimetic-type conversion of β-himachalene into oxidohimachalene employing photochemical hydroxylation or "copper peroxide" oxygenation is reported

Studies in sesquiterpenes-LIII: Deodarone and atlantolone, new sesquiterpenoids from the wood of Cedrus deodara loud

Isolation and structure determination of a novel bisabolane-based tetrahydro-γ-pyrone from the essential oil from the wood of Cedrus deodara Loud is described. The compound, which has been named deodarone, has been chemically correlated with the sesquiterpene ketone, atlantone. An hydroxy ketone, designated as atlantolone, has also been isolated. This compound appears to be the precursor of the new C<SUB>12</SUB>-ketone, recently described as a component of the essential oil of Cedrus atlantica Manet
