The decay properties of the neutron deficient nuclei $ sp{144}$Gd, $ sp{142}$Gd, $ sp{ rm 141g}$Gd, $ sp{ rm 141m}$Gd and $ sp{140}$Gd are investigated in detail for the first time and the new beta decaying isomers $ sp{ rm…

This study analyses the diffusion of numerically controlled machine tools in sixty Quebec and Ontario engineering and metalworking firms. Interviews with production management provide the data for a critical evaluation of labour process analysis and economic diffusion theory. Management decisions…

Measles virus is an animal enveloped virus that is a member of the genus morbillivirus in the paramyxoviridae family. Its envelope contains two surface glycoproteins H and F which are required for viral attachment and entry respectively. Virus penetration occurs…

The principles of Tribology are introduced to the general problem of tyre-soil interaction with a view to development of a better knowledge of the manner in which the tyre-soil interface behaves under rolling motion subjected to tractive force. In essence,…

The experimental work presented in this thesis explores, in anaesthetized and mid-collicular decerebrate, unanesthetized, cats, the properties of two components of the discharge of sympathetic nerves which are time-locked to the central respiratory cycle and are presumably generated within the…

Solid residues are generated at various stages of metal production. Some of these residues still contain significant quantities of metals. In determining possible process routes for residues a detailed knowledge of the mineralogy (i.e. the minerals or phases present) is…

Contemporary ideas on science learnin is useful to avoid the failure of traditional teaching related to preconcepts or conceptual errors in both students and teachers. In this context is introduced to the study of light trhough the knowledge of the…

This study delineates practical knowledge bases that university professors draw upon during exemplary Critical Incidents of teaching. One hundred and eight full-time, tenure track, university professors from departments of Biology, Chemistry, Economics, Engineering, English, History, Math, and Philosophy across the…
