Effects of prescribed burning on mycorrhizal fungi in a pinus banksiana stand
(1997)The purpose of this study was to examine the effects of fire on mycorrhizal fungi in a Pinus banksiana stand. It was hypothesized that an optimal fire intensity leads to an increase in ectomycorrhizal colonization of ... -
Effects of radiation therapy knowledge and misconceptions on patient anxiety
(1996)Radiation therapy often produces considerable anxiety in patients. One reason for this anxiety is the uncertainty that often surrounds this treatment. Since studies have shown that many patients experience the most distress ... -
Effects of regular long term hemodialysis on serum electrolytes and parathyroid hormone levels
(1978)Regular long term hemodialysis is the accepted method of treatment for patients with advanced renal failure. While it is effective in maintaining a patient in reasonably good health for long periods of time many problems ... -
Effects of resistance training on selected physiological parameters
(1989)The literature presents contradictory statements concerning the effectiveness of free weights, isokinetic devices and plyometric exercises on the development of lower extremity power, and lean body mass {Coyle, Feiring, ... -
Effects of roads and log hauling on woodland caribou use of a traditional wintering area near Armstrong, Ontario
(1997)Increasing concern for the viability of forest-dwelling woodland caribou (Rangifer tarandus caribou) in Ontario has resulted in recommendations for more restrictive timber harvesting practices. Caribou populations have ... -
Effects of seed sources and fungi on ectomycorrhizal formation and growth of containerized tamarack seedlings
(1985)The objectives of this study were to investigate the host specificity of mycorrhizal fungi to tamarack (Larix laricina (Du Roi) K. Koch.) in pure culture synthesis and to examine the effects of seed sources and fungal ... -
Effects of selected biotic and abiotic factors on growth and survival of young crayfish, Orconectes virilis (Hagen)
(1988)The growth and survival of Orconectes virilis young was studied in 50 x 50 x 50 cm lake enclosures during the summer seasons of 1986 and 1987. The effects of density (12/m2, 40/m2, 160/m2), substrate (mud, sand, ... -
Effects of selected mountain bike front suspension forks on handlebar vibration and ground reaction forces
(1997)The purpose of this investigation was to compare the effectiveness of two types of mountain bike front fork suspension systems for controlling ground reaction vibration at the handlebar upon impacting a raised surface. ... -
