ore than thirty years of language immersion instruction in Canada and the United States have produced an impressive body of research demonstrating its benefits to students. This research indicates that students gain proficiency in a second language, develop cultural awareness, and perform as well as or better than their non-immersion peers on English proficiency tests (Rubio, 1998). As a result...

Abstract Brassavola nodosa (L.) Lindl. is an epiphytic orchid with great potential for the ornamental plant industry. The lack of information on propagation and production techniques limits development large-scale commercial production. Furthermore, this species experiencing a reduction in population due to habitat destruction, impact climate change, over-collection from native habitats. This s...

The bioactivity of a series of fluoride-containing sodium-free calcium and strontium phosphosilicate glasses has been tested in vitro. Glasses with high fluoride content were partially crystallised to apatite and other fluoride-containing phases. The bioactivity study was carried out in Tris and SBF buffers, and apatite formation was monitored by XRD, FTIR and solid state NMR. Ion release in so...

Two types of end milling at partial radial immersion are distinguished in this work, namely; up and down end-milling. They are theoretically given comparative study for a three tooth end miller operating at 0.5, 0.75 and 0.8 radial immersions. 0.5 and 0.8 radial immersion conditions are chosen so that analysis covers situations in which repeat and continuous tool engagements occur while 0.75 ra...

Background: This study investigated the color stability of reline resin after microwave disinfection and immersion in drinks for

Cold thermoregulatory models (CTM) have primarily been developed to predict core temperature (T(core)) responses during sedentary immersion. Few studies have examined their efficacy to predict T(core) during exercise cold exposure. The purpose of this study was to compare observed T(core) responses during exercise in cold water with the predicted T(core) from a three-cylinder (3-CTM) and a six-...

r SUMMARY The tests were made in the jft x jft tunnel to assess the performance of a rectangular twin-duct intake, including effeots of limited immersion of the intake xnto a wing boundary layer. The effects in one duct, arising from interference caused by varying the flow through the other, have slso been mvestigated. Partial immersion of the lntske into the wing boundary layer causes little d...
