effect of seasonal training on selected physical and physiological variables of junior male alpine ski racers
(1990)the purpose of this study was threefold: 1) to investigate the effect of seasonal training on anthropometry, muscular strength and power, motor ability, flexibility, aerobic power, and anaerobic power and capacity, 2) ... -
effects of isometric exercise versus electrical muscle stimulation on serum enzymes, plasma lactate and peak torque levels in males
(1989)the purpose of the study was to examine the effects of electrical muscle stimulation (ems) and isometric exercise (ie) on peak torque, plasma lactate and serum enzymes. the subjects were 14 male volunteers aged 22-41. ... -
use of musical reinforcement to improve practice behaviors of competitive swimmers
(1989)the rationale for the study was to determine if music could be used as an effective reinforcer for increasing appropriate practice behaviors, and reduce problem behaviors in the competitive swimming environment. the ... -
effects of electrical stimulation, isokinetic exercise and concurrent isokinetic exercise with electrical stimulation on acquisition and retention of strength, endurance and bilateral transfer in females
(1985)the purpose of this study was to examine the effects of four different training methods (isokinetic exercise, electrical muscle stimulation, concurrent electrical muscle stimulation with isokinetic exercise, and no ... -
effects of electrial stimulation and isokinetic exercise on serum enzymes and electrolytes
(1986)the purpose of this study was to determine the effects of short-term electrical stimulation of the quadriceps muscle, isokinetic leg extension and flexion exercise, and combined electrical stimulation and isokinetic ... -
operant conditioning of spitting behaviour in the archer fish (toxotes jaculator)
(1989)the archer fish, toxotesjaculator, has the ability to knock insects out of the air by spitting at them. although many studies have been done using the archer fish, it has never been considered from the operant conditioning ... -
density dependent extinction : phase ii
(1993)in two separate experiments, an 8 rat 8 station operant arena was used to study resistance to extinction to test learning and optimal foraging theories of behaviour. the learning theory, called the generalized decrement ... -
risk sensitive foraging by rats in the operant arena
(1988)the operant arena was used as the framework in which to study the theory of risk-sensitivity, a small colony of hooded rats was exposed to increasing work demands while given the choice between simultaneous fixed ratio ... -
risk-sensitivity in a rat population under interval schedules of reinforcement : open and closed economies
(1995)a group consisting of eight male hooded rats was tested for risk-sensitive foraging preferences in an eight station operant arena, under conditions of open and closed economies. the group could choose to forage at either ... -
observation of behavioral principles in baseball performance
(1984)three studies were done to demonstrate that formalized sports can be used to test or observe the operation of psychological phenomena. major league baseball was chosen as the representative sport, in part because of ... -
variable interval schedule control of dispersion and density
(1984)the effects of variable interval (vi) schedules of reinforcement on the dispersion patterns and aggregate densities of a small population of rats was studied. eight male rats were permanently housed in an arena in which ... -
social facilitation of extinction in rats
(1991)theories of resistance to extinction such as the generalized decrement theory (gdt) have been largely based on research involving isolated individuals. in the natural environment however, extinction, like acquisition ... -
the geology, petrology, geochemistry, sulphide and platinum-group mineralization of the quetico intrusions, northwestern ontario
(1992)the quetico intrusions are a group of small, geochemically primitive, locally cu-ni-pge-rich, mafic to ultramafic intrusions closely associated with the margins of the quetico batholithic complex. they are composed ... -
study of the third dimension in the thunder bay silver veins : fluid inclusion and stable isotope results
(1988)"historic drill core from the shuniah mine and more recent drill core from the keystone and porcupine mines have provided the basis for a study of these past silver-producing veins as a function of depth. precipitation was ... -
granitoids and rare-element pegmatites of the georgia lake area, northwestern ontario
(1985)the georgia lake pegmatite field is located in the quetico gneiss belt of the superior province. spodumene-bearing and subordinate beryl-bearing pegmatites of the georgia lake area are flanked to the south and east by ... -
petrographic and fluid inclusion studies on the metalore-golden highway deposit, thunder bay district, ontario
(1993)the gold-bearing metalore shear zone and golden highway quartz-carbonate vein in the beardmore-geraldton archean greenstone belt occur along the paint lake splay faults at the contact between metavolcanic rocks and ... -
study of zonation at the nanisivik zn-pb-ag mine, baffin island, canada
(1985)zn-pb-ag mineralization at nanisivik, northwest baffin island, is hosted by proterozoic, laminated dolostone of the society cliffs formation. mineralization of the main orebody is highly variable in terms of texture and ... -
survey of the mainland and island belts, thunder bay silver district, ontario : fluid inclusions, mineralogy, and sulfur isotopes
(1987)the thunder bay silver district is composed of two curvilinear groups of veins, the mainland and island belts. the veins can be mineralogically divided into the barren, silverbearing, and 5-element association veins. during ... -
nmr study of aqueous tetraalkylammonium silicates
(1994)silicon-29 nuclear magnetic resonance (nmr) spectroscopy has been used to investigate the equilibrium distribution and kinetics of silicate oligomers in aqueous tetraalkylammonium silicate solutions. certain tetraalkyl ... -
periphyton community dynamics in varying natural environments : a study from northern lake simcoe
(2014)study site : near barrie ontario, kempenfelt bay - barrie ; concession point - ramara township ; lagoon city, brechin. globally, freshwater ecosystems are constantly under the threat of various biological and chemical ...
