Selection of algal genotypes by three species of lichen fungi in the genus Cladonia
(2004-07-31)
The lichen-forming fungal genus Cladonia P. Browne associates with green algae in the genus Trebouxia de Puymaly. Genetic structure of the algal symbionts in Cladonia gracilis (L.) Willd., Cladonia multiformis G. Merr., ...
Instability of dykes at Seven Sisters Generating Station
(2004-10-12)
Water-retention dykes at Seven Sisters Generating Station in Manitoba have experienced irregular instabilities since they were heightened in the late 1940s. An investigation was undertaken to compare three locations at the ...
Pattern of insulin delivery affects hepatic insulin sensitizing substance (HISS) action and insulin resistance
(2004-12-31)
Hepatic insulin sensitizing substance (HISS) action accounts for 55% of the glucose disposal effect of a bolus of insulin in the fed state. To determine the effect of continuous versus pulsatile insulin delivery on HISS ...
Host-parasite interactions in tan spot [Pyrenophora tritici-repentis] of wheat
(2003-12-31)
Tan spot of wheat, caused by the ascomycete Pyrenophora tritici-repentis, is an economically important disease in all the major wheat growing areas worldwide. Even though the pathogen was known to occur on grasses and ...
Two large-scale sealing tests conducted at Atomic Energy of Canada's underground research laboratory: the buffer-container experiment and the isothermal test
(2002-06-30)
Two large-scale sealing experiments were conducted at Atomic Energy of Canada Limited's Underground Research Laboratory at Lac du Bonnet, Manitoba. The rate of water uptake in densely compacted sand-clay buffer materials ...
The effect of anisotropic elasticity on the yielding characteristics of overconsolidated natural clay
(2001-02-16)
Quantitative application of elastoplastic theory to the yielding behaviour of natural soils has always been uncertain. Part of the reason is that the theory was developed for reconstituted materials with isotropic structure, ...
Small reflector antenna with low sidelobes
(2003-10-31)
A prime focus low sidelobe parabolic reflector antenna with self-supported feed is designed for low sidelobe, applications. The parabolic reflector diameter is between I nine and 12 wavelengths. A simple design is achieved ...
Increased incidence of hepatic insulin-sensitizing substance (HISS)-dependent insulin resistance in female rats prenatally exposed to ethanol
(2005-04-30)
Insulin causes the release of the hepatic insulin-sensitizing substance (HISS) from the liver. Hepatic parasympathetic nerves play a permissive role in the release of HISS. HISS-dependent insulin resistance (HDIR) occurs ...
Thermophilic anaerobic acid digestion of biosolids: hydrolysis, acidification, and optimization of retention time of acid digestion
(2006-05-31)
The objective of the study was the optimization of the retention time in a thermophilic acid digestion system. To achieve this optimization, acidification index defined as the ratio between acidification rate and hydrolysis-rate ...
The effect of Frankia and Paxillus involutus on the performance of Alnus incana subsp rugosa in mine tailings
(2005-11-30)
The purpose of this study was to determine whether symbiotic nitrogen-fixing bacteria and mycorrhizal fungi act synergistically to improve plant performance when grown on heavy metal mine tailings. Seedlings were inoculated ...
