The study of cooperative work as a socially-situated activity has led to a focus on providing 'mechanisms' that more closely resonate with existing work practice. In this paper we challenge this approach and suggest the flexibly organised nature of work is better supported when systems provide a 'medium' which can be tailored to suit each participant's needs and organised around the detail of t...

-In today’s world designing adaptable course material requires new technical knowledge which involves a need for a uniform protocol that allows organizing resources with emphasis on quality and Learning. This can be achieved by bundling the resources in a known and prescribed fashion called Learning objects. Learning Objects are composed of two aspects namely “Learning “ and “Object”. The Learn...

Adding astutely placed methyl groups to hexaphenylbenzene increases molecular weight but simultaneously weakens key C-H···π interactions, thereby leading to decreased enthalpies of sublimation and showing that materials with abnormally weak cohesion can be made by identifying and then obstructing interactions that help control association.

Theories of the Origin of Life can be categorised as ‘template replication first’ and ‘metabolism first’. A key question for metabolism first theories is the mechanism for transfer of inherited information. Earlier work presented a mechanism based on catalytic cycles, along with supporting results from the SimSoup artificial chemistry simulator. The current paper presents an enhanced SimSoup mo...
