Virtual technology is now routinely used for meetings of large, multi-location organizations (Vandenburg and Reese, 2011), and shows great promise for bringing together geographically dispersed participants in facilitated discussions, as long as participants are familiar with the technology and comfortable using it. In most instances, it makes sense to conduct facilitated sessions in a face-to-...

This paper reports research into the student experience of learning through discussions in a blended environment. Third year engineering students studying e-commerce engaged in both face-to-face discussions and online asynchronous discussions as key aspects of their learning experience. Adopting a quantitative methodology, questionnaires based on what students thought they were learning through...

Calix (4) pyrroles are macromolecules structurally related to porphyrins, they exhibit exceptional chemical and physical properties that have suggested a vast number of potential applications in host-guest chemistry. In recent years, calix (4) pyrroles have attracted a lot of attention because of their properties as binders of anions, transition metals, and neutral substrates and their new appl...

It was suggested that the enhanced incorporation of choline into phospholipids in the very first stages of renal compensatory hypertrophy might result in a change of membrane fatty acid composition and of membrane fluidity (S. Solomon). L. M. Lowenstein stated that no data on fatty acid composition of kidneys undergoing compensatory hypertrophy were available. Since ligation of the ureter of th...

Answering questions by N. Bank and F.H. Epstein, J.-P. Guignard stated that the increase in sodium excretion (?) with bicarbonate excretionfollowing clamping ofthe contralateral renal pedicle in dogs could not be ascribed to an increase in extracellular volume because, in his experiments, extracellular volume was kept constant by adapting the infusion rates to the urineflow observed in the prec...
