Transfer of chirality during the build-up of molecules has been applied innumerable times in organic chemistry since the end of the 19th century, when it was introduced in the so-called asymmetric synthesis by E. Fischer. Although analogous reactions were introduced in co-ordination chemistry in its early development, diastereoselective reactions have not been applied in a very systematic way f...

Eye-head co-ordination of patients with Parkinsonism and cerebellar ataxia was investigated and compared with that of normal subjects. In Parkinsonian patients eye-head co-ordination was of the same pattern as normals, with an accurate and stable gaze. Reaction times for both eyes and head, however, were prolonged. It was also noted that the contribution of head movements to gaze shift was abno...

Ordination is the part of statistical ecology which has developed and integrated in recent years. Finding environmental factors which important in ecological structure determination of plant species is the final purpose of ordination. Ordination method was used for finding the effect of important variables on Bromus tomentellus species quantitative and qualitative changes in Esfahan's Fereidan ...

Vegetation is the most important factor influencing the sustainability of rangeland ecosystems. Therefore, it is important to understand the environmental factors and their effect on vegetation and restoration of rangeland ecosystems. The aim of this study was to identify factors influencing on Gundelia tournefortii L. distribution. Accordingly, the information of Gundelia tournefortii L. was d...

Engineering component-based software systems in a distributed fashion is challenging. Particular issues to address include software process and work co-ordination, sharing and collaborative editing of component specifications, designs and implementations, and appropriate sharing of reusable components. This paper describes our approach to tool support for distributed component engineering. Seve...

Web services can be seen as a newly emerging research area for Service-oriented Computing and their implementation in Serviceoriented Architectures. Web services are self-contained, self-describing modular applications or components providing services. Web services may be dynamically aggregated, composed, and enacted as Web services Workflows. This requires frameworks and interaction protocols ...

The objective of this paper is to discuss how to use Information Technology to enable the staff at a mission-critical order packaging department to cope with a drastically increasing scale of operation. To reduce the risk of interrupting the production, a cultivation approach is adopted. We use co-ordination theory to analyse the current work setting and present a design proposal. The basic bui...
