The Radio Canada International news and current affairs program "Canadian Journal" is used as a case study to develop an adequate theory of news work. A theory of news structuration is proposed which seeks to overcome the dichotomy between agency…

This thesis critically reviews medical journal literature on the physician-patient interview. The review focuses on literature which is written by and for physicians, in Canadian and American, English language medical journals. Articles, essays and letters to the editor are examined…

The detrimental effects of Phomopsis spp. on seed germination of soybean [Glycine max (L.) Merrill] are broadly recognized. Rolled paper toweling is the most widely used method for testing germination of soybean seed. The validity of the rolled-paper-towel test to…

Seventy-three seed samples of 23 soybean [Glycine max (L.) Merr.] cultivars produced in Florida in 1986 were analyzed for germination, vigor [tetrazolium (TZ) test], and presence of seedborne pathogens. Thirty percent of the samples contained from 5 to 20% (high)…

This study examines the relationship of Sir Sayyid Ahmad $ underline{ rm Kh}$an with the Indian $ sp{ rm c}$ulama'. As part of his reform movement, and in particular through his journal Tahzibu'l-Akhlaq, Sir Sayyid launched a severe attack on…

Real Benoit (1916-1972), a native of Sainte-Therese-de-Blainville, studied at Sainte-Therese Seminary and at Sainte-Croix College. His early career in journalism involved writing for "Le Soleil", "Le Petit Journal", "La Presse", "Horizons", "Le Jour" and "Regards". In the latter publication his…

An afocal two-element holographic imaging system is presented. This system can be used to work in white light. The holographic optical elements (holographic lenses) are made as thick phase holograms on silver halide sensitized gelatin (SHSG) and they present a…

Based on the results of the coupled-wave theory the diffraction efficiency is calculated for thick phase transmission holographic gratings taking into account the chemical processing of the recording material. Three effects of processing are considered: variations in the average refractive…

The experimental results of diffraction efficiency as a function of the geometrical disposition of recording beams in bleached silver halide transmission thick-holographic gratings are presented. Two variables have been used to relate these results with certain geometric parameters. These variables…

A statistical model is used to study the formation of noise gratings in holograms and the mechanism that causes radiation scattering in them. The theoretical model presented describes noise scattering in terms of diffraction due to the high number of…
