<p>Quaternary sediments exposed in the banks of the Severn River, Hudson Bay Lowlands, are interpreted as components of four distinct types of depositional complexes. Overconsolidated massive diamicts displaying strong clast fabric orientations and containing channelized, sub-glacial fluvial deposits and glacially shaped clasts, comprise the majority of sediments in the study area. These are interpreted as components of a lodgement till complex. Thin massive diamict units which often display random clast fabric orientations, and laminated fine-grained sediments containing dropstones and diamict clots often occur near the tops of sections. These are interpreted as components of either a glacio-lacustrine or glacio-mairne depositional complex is composed of fossiliferous beach contained in the sediments. An uniquely marine complex, depending on the abundances of formainifera depositional gravels, and estuarine silts and sands. This complex is found only at the very tops of sections, and was probably deposited in the post-glacial Tyrrell Sea. Three distinct ice flow orientations were defined by clast fabric analysis, and measurement of striations on boulder combining these pavements and bedrock surfaces. Three separate lodgement till complexes are identifiedby combining ice flow orientations with data on formainifera abundances, erratic clast lithologies and diamict matrix colours. These lodgement complexes were deposited by ice flowing from three separate ice domes; an earlier Patrician dome, a middle James Bay dome and a younger New Quebec dome.</p> / Bachelor of Science (BSc)

<p>Dynamic muscle strength (1 RM), symptom limited treadmill endurance, and bone mineral density and content, were compared among three groups (5 males and 5 females in each group) of elderly subjects (mean age of72.5 years) who had either continued to weight train twice per week for 5 years (TR), ceased to weight train after 2 years (DETR), or had acted as controls throughout (CON). The TR and DETR trained hard (progressing up to 3 sets at up to 80% of I RM) for 2 years; the TR continued training for an additional 3 years at a maintenance level (2-3 sets at 60-70% 1RM), whereas the DETR stopped training; the 10 CON subjects did not train for the duration of the study but took part in identical testing procedures. After two years of resistance training, dynamic strength in the TR and DETR groups increased significantly above the baseline and CON values for all exercises (p<0.0001). Following 3 years of maintenance level training, leg press, arm curl, and bench press 1 RM (sum of both limbs) in the TR remained 21.6kg (17%), 15.7kg (82%), and 8.3kg (34%) above baseline values respectively. The I RM in the DETR were 18.4kg (14%), 5.3kg (24%), and 1.4kg (9"10) above baseline for leg press, arm curl, and bench press after 5 years, whereas the CON declined over the 5 year period by 18.4kg (9.7%), 4.4kg (19"10), and 3.5kg (6%) respectively. There were non-significant improvements in treadmill performance in the TR and DETR and decline in the CON after 2 years of resistance training. Treadmill performance declined between years 2 and 5 in all groups. Bone mineral density and content were not different among the groups across all time points. We conclude that: 1) The strength gains from long-term resistance training in the elderly are not entirely lost even after 3 years of detraining, 2) The effects are specific to the exercises performed in the training program.</p> / Master of Science (MS)

<p>Thirty women (20-22 y) were randomly assigned to 3 groups of 10: a total body (TB) and a split body (SB) training groups and control group. The SB group performed 4 strength training sessions per week (two upper and two lower body), while the TB group trained both upper and lower body muscle groups together, twice weekly. It took 45-60 minutes to complete training either the upper or lower body muscle groups. Training consisted of five sets of 6-12 repetition maximum (RM) per exercise for 20 weeks. In comparison to the control group, the trained groups decreased relative fat mass (dual-energy x-ray densitometry, -1. 2%, P < 0.006) and increased whole body (3.3%, P < 0.001) and combined arm lean mass (10.0%, P < 0.007) as well as 1 RM (P < 0.0005) arm curl (73%), bench press (28%) and leg press (22%) strength. In contrast, training caused no increase in electrically evoked twitch peak torque or motor unit aotivation (interpolated twitch method) for right knee extension or elbow flexion. Only elbow flexion increased in maximum voluntary isometric strength. Arms were more responsive to training than legs. There appeared to be a trend toward greater gains in strength and muscle size with TB training. However, these differences were not statistically significant. No advantage resulted when a total body strength training session of less than 2 hours was split into separate upper and lower body workouts.

<p>Maximal weight-lifting performance, isometric strength, isokinetiic torque, whole muscle and individual fibre cross-sectional areas, and muscle evoked contractile properties were assessed in 14 elderly males before and after 12 weeks of weight-lifting training. Dynamic elbow flexion training of one arm resulted in a significant 48% mean increase in the maximal load that could be lifted once (1 RM) and a smaller improvement in isokinetic torque (8. 8%) but no change in isometric strength. In the contralateral control arm, 1 RM and isokinetic torque increased by 12.7 and 6. 5 %, respectively, but isometric strength did not change. The interpolated twitch technique confirmed complete motor unit activation during a maximal isometric contraction of the elbow flexors before and after training. Bilateral leg press training effected mean increases of 17 and 23% in isokinetic torque and dynamic lifting capacity, respectively. The mean maximal cross-sectional area of the elbow flexors (biceps brachii and brachialis) increased by 17.4% in the trained arm but did not change in the control arm. The increase in the mean area of the Type II fibres in the biceps brachii muscle in the trained arm (30.2%) was greater than the corresponding change in the control arm (10.7%, P< 0.05). The most significant change in the the evoked contractile properties of the trained elbow flexors was the increase in twitch half-relaxation time. It is concluded that older individuals retain the potential for significant increases in strength performance and upper limb muscle hypertrophy in response to overload training.</p> / Master of Science (MS)

Capillary electrophoresis is currently a very powerful technique for the analysis of seized drugs. A rapid analytical CE method for the screening and quantification of GHB and GBL was achieved using 300mM CTAC/25mM phosphate buffer pH 6.3. Reversed phase HPLC was achieved using 25mM phosphate buffer pH 6.5 and a Cl8 Aqua column. Chiral separation of 9 amphetamine type stimulants was obtained using a highly sulfated gamma-cyclodextrin as a chiral selector. MECC and CZE were compared for the analysis of psilocybin, while a rapid and robust method is presented for the analysis of major opium alkaloids, using dynamically coated capillary columns. The column is coated with a polycation followed by a polyanion coating, using a commercial reagent kit. Using a background electrolyte pH of 2.5 with the addition of hydroxypropyl-beta- cyclodextrin and dimethyl-beta-cyclodextrin, the analysis of morphine, papaverine, codeine, noscapine, and thebaine in opium samples was obtained with great resolution. Finally, separation of common benzodiazedpines was also investigated using CZE and a pH 2.5 phosphate buffer.

The effects of vegetation-manipulative practices on habitat use by sharp-tailed grouse (Pedioecetes phasiane11us columbianus) were studied during the period 1974-1975 in Curlew National Grasslands, Oneida County, Idaho. Vegetational transects were run twice each month during the growing season of May-August, 1974-1975, to assess vegetational differences between treatments. Transects were run ~ to estimate sharp-tailed grouse use on the eight study areas .twice monthly. Vegetational plots were used at each sharp-tailed grouse observation site to determine correlates of vegetation types and grouse use. Chained areas were used heaviest by grouse during the study period suggesting that chaining created the most preferred habitat. Cover, edge, and slope were also important factors at sites of sharp-tailed grouse occurrence. Recommendations are made on manipulative methods and other means to improve sharp-tailed grouse use of habitat.

<p>Subject Category "Geology" not listed in menu.</p> / <p>An Alkalic suite of proterozoic volcanics and their associated sediments, situated within the Dubawnt Group of the Churchill Province, was mapped and studied. Petrography and geochemical analyses were performed on representative specimens. The extrusives and related dykes are thought to have been derived from the differentiation of a single parent magma, as evidenced by several geochemical trends. The units are as follows; intermediate to felsic trachytes and pyroclastics, typically phlogopite phyric and red alkali rhyolites; later volcaniclastic units. A significantly younger diabase dyke cuts these units, all of which overlie the '307' formation.</p> / Bachelor of Science (BSc)

The most efficient wildlife research programs and the most satisfactory methods of applying their results are greatly enhanced if the information is present in such an interesting and understandable manner that it becomes of practical value ot the people. Extension education has the function of translating the results of research into usable form and presenting it to the people. The development of a wildlife extension program is based on the needs of the people, and the various phases of the program are designed to meet and solve wildlife probems confronting the people. The purposes of this study are: 1. To determine the possible need for a wildlife extension program in Utah. 2. To determine the extent of national need for wildlife extension work. 3. To sumarize the extension programs in states now having a wildlife extension service. 4. To develop a guide to wildlife extension work in Utah.

Waterfowl utilization was recorded by observing study units at different elevations from the time water areas were thawed in the spring until they were frozen in the fall. Sixteen species of waterfowl were observed in the Uinta Mountain; mallards, green-winged teal, pintails, and ring-necked ducks were breeders. Ninety-eight percent of all waterfowl observed were below 10,000 feet. Waterfowl numbers were highest during migratory periods and lowest in the breeding season. Adult waterfowl were observed most often on natural water areas and beaver ponds greater than one acre. Water areas at lower elevations had high indices of aquatic invertebrates and contained aquatic plants with high seed producing capabilities whereas water areas at high elevations had little water-fowl food.

One of the important elements in the cycle of water movement from the time it falls on the surface of the land as rain or snow until it reaches the ocean, is evapo-transpiration or consumptive use of water. This subject is becoming increasingly more important, particularly in the irrigated regions of the West. It involves problems of water supply, both surface and underground, as well as those of management and general economics of irrigation projects. The purpose of this study was to obtain basic information regarding the consumptive use of water by standard crops in the Upper Colorado River Area of Utah. This information is needed to determine the flow depletion at Lee's ferry resulting from diversions from the river in the basin above. From these data, it will be possible to estimate the water supply available for future development and to predict the water supply needs for individual projects which may be proposed. in addition, the consumptive use data may well be used as a vasis for adjudication of water rights or arbitration of controversies over major stream-systems where the public welfare of valleys, states, and even nations is involved.
