The spectre of COVID-19 and its global transformational legacy on all aspects teaching learning overshadows this issue the Canadian Journal Learning Technology. near-universal demand for remote reliance technologies not only transformed educational environment but also shifted many preconceived notions about interplay between dissemination knowledge technology. surge in technology's prominence ...

Nanoporous metal prepared by the corrosion of an alloy can take the form of monolithic, millimeter-sized bodies containing approximately 1015 nanoscale ligaments per cubic millimeter. Applications have been suggested, for instance in catalysis, sensing and actuation. Although the process of dealloying has seen many studies, the underlying processes remain to be clarified in more detail. Here we...

Lack of agreement among definitions of COPD, combined with delayed diagnosis in many patients, makes estimates of prevalence difficult. In 2008, 13.1 million U.S. adults (aged 18 and older) were estimated to have COPD, but close to 24 million U.S. adults have evidence of impaired lung function, thus indicating underdiagnosis of COPD. COPD accounted for 1.5 million emergency department (ED) visi...

O computed tomography there was extensive soft-tissue swelling of the cecum with a calcified fecalith (Fig. 2, arrow), which suggested diverticulitis. The patient was treated conservatively with antibiotics, and a few days later underwent a water-soluble contrast enema examination to exclude malignant disease of the cecum. This examination revealed a solitary cecal diverticulum with no evidence...

THE breakdown of liver glycogen which occurs as one of the chief mechanisms controlling the blood sugar level has generally been ascribed to the liver amylase, but it has recently been suggested that the main path of glycogen breakdown may be through a phosphorylating system involving a phosphorylase which forms hexosephosphate and a phosphatase which hydrolyses the hexosephosphate to glucose [...

have been several attempts to develop an artificial bladder. To a large extent appropriate results for the use of alloplastic materials have been mentioned in lectures, but have not been published so far. The reason for this was, on the one hand, the lack of development of suitable materials, and on the other a lack of ideas for realistic, active concepts. As a clinical user of bladder substitu...
