application of a physically based hydrological model on a semi-arid watershed in northern ghana
(1997)land degradation in semi-arid environments is increasing due to rapid population growth, poor landuse practices and variable climate conditions. landuse planners require a better understanding of the impact that proposed ... -
effect of gustatory stimulation on endurance performance
(1997)the purpose of this study was to determine whether the ingestion of an energy-free aspartame beverage (asp) (99 mg aspartame/l) would influence endurance performance relative to a water (wat) trial. nine trained male ... -
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. ... -
structure and mobility of lignin in relation to pulp washing and bleaching
(1997)the roles of molecular size and structure were investigated in relation to the extent of peroxide bleaching and lignin adsorption on pulp. structural analysis of components from effluents generated by peroxide bleaching ... -
physiological and biomechanical profile of the athletes competing in a world cup cross country ski relay event
(1997)a variety of studies have been conducted which have attempted to relate biomechanical and physiological variables to cross-country skiing performance. these investigations have taken place in different settings including ... -
pregnancy : a social construction
(1997)departing from conventional social science approaches to pregnancy and the pregnant woman’s body this study examines pregnancy as experience", a socially constructed state of being where attitudes about sexuality and ... -
potential impacts of clearcut logging on lake trout (salvelinus namaycush) reproduction in northwestern ontario lakes
(1997)lake trout reproductive habitat was characterized in three small lakes, 250 km northwest of thunder bay, ontario, by measuring the physical characteristics of preferred spawning habitat including 1) depth, 2) substrate ... -

(1997)the purpose o f this study was to investigate functional, histochemical, biochemical and morphological properties associated with resistance training in the elderly. ten (8 females, 2 males), moderately active sexagenarians ... -
old-growth forests and timber supply : a case study from the boreal forest
(1997)historically in canada, old-growth forest preservation concerns, research, and analyses have centred on the stately coniferous forests of british columbia (e.g., clayoquot sound). within the past decade, however, the ... -
pulse fishing of a walleye population : response, recovery and management implications
(1997)the response of the henderson lake boreal fish community to a large scale exploitation of walleye was studied. the pulse fishery removed approximately 89 percent (3226) of adult walleye (1980-82) from henderson lake ... -
effects of alternative conifer release treatments on terrestrial gastropods of regenerating spruce plantation
(1997)this study examined changes in terrestrial gastropod densities and species richness associated with alternative methods of managing competing vegetation on regenerating spruce plantations. data were collected monthly ... -
effects of harvesting, prescribed burning and wildfire on soil chemical properties in northwestern ontario
(1997)soil chemistry responses to disturbances were quantified and compared at two dates by sampling the organic, 0-5 cm and 5-10 mineral soil layers in a northwestern ontario boreal mixedwood site. the disturbance treatments ... -
exciton operators : commutation relations and dynamics
(1997)the electron-hole pair operator commutation relations for a semiconductor are explicitly derived showing that the pairs are quasi-bosons with statistics intermediate between bosons and fermions. these pair operators are ...
