Biscoe (1986) states, the key to overcoming this is the recognition that computers merely act as a mechanism for the storage and retrieval of information. Other factors that influence the health system stem from the fear of losing control...
متن کاملUltrasonic system for continuous washing of textiles in liquid layers.
The use of ultrasonic energy for washing of textiles has been tried several times without achieving practical development. In fact, the softness of the fibres makes the cavitation to produce small erosion effect and the reticulate structure of the fabric favours the formation of air bubble layers which obstruct wave penetration. In addition, a high proportion of water with respect to the wash l...
متن کاملThe canacla, a new technology for hand washing

متن کاملA convenient method for preparing rigid-core ionic liquid crystals
An efficient, solvent free method for the N-arylation of imidazole by 1-(dodecyloxy)-4-iodobenzene using Cu(II)-NaY as catalyst and K(2)CO(3) as base is reported. By this synthetic approach, mesomorphic 3-[4-(dodecyloxy)phenyl]-1-methyl-1H-imidazol-3-ium iodide was synthesized in a two-step procedure, and its mesomorphism has been fully investigated by polarised optical microscopy, differential...
متن کاملPreparing for Technology-Related Organizational Change An Activity-Theoretical Perspective
ICT-related change is usually studied from the point when a technological artifact has arrived in an organization. Applying an activity-theoretical lens, this paper explores the contradictions within a medium-sized organization’s central activity system, the manifestations of which motivated the decision to engage in a substantial change and shaped the object of the initiative. It illuminates t...
