The achievements of the Eastern Rockies Forest Conservation Board are considered relative to its stated objectives, the Board's concept of multiple-use and the present condition of watersheds on the Eastern Slopes . Priorities and pre- requisites for effective implementation of those directives are then examined.Item Embargo Effects of specific solvation on kinetic activation parameters of some benzyl halides in binary solvent mixtures(1963) Wills, Ronald; Hyne, James BissetItem Embargo An Electron microscopic study of the sub-oesophageal ganglion of the cockroach, Periplaneta Americana(1963) Emberson, John W.; Challice, Cyril E.Item Open Access Error correcting codes for asymmetric paths(1963) Fenyvesi, C.

Rapson; Oliver, Thomas A.Item Embargo A Functional comparison of the central retail district with two regional shopping centres in Calgary, Alberta(1963) Johnson, Denis Bruce; Boal, Frederick W.Item Embargo The Glacial geomorphology of the Upper Red Deer River Valley, Alberta(1963) McPherson, Harold James; Nelson, James GordonThe major purpose of this study was to describe and interpret in terms of process the landforms created during the deglaciation of the mountainous upper Red Deer river valley. A review of the literature suggested two possible ways in which ice may have retreated during deglaciation. The ice may have retreated in a series of stillstands with recessional positions of the ice marked by end or recessional moraines and associated outwash deposits. Or alternatively, the ice may have stagnated and retreated mainly by melting and lowering in place. This latter idea, first suggested by the Scandinavian school of geomorphologists has been applied to the interpretation of the landforms of the Canadian prairies. Until the present study, however, its possible applicability to alpine landforms in Alberta had not been investigated. The procedure in this study was to map various kinds of drift in the upper Red Deer valley and to interpret the deposits from the standpoint of deglacial process. In addition, detailed studies in the Red Deer river channel were begun. Stakes were placed by plane tabling at a number of localities in the channel with a view to measuring rates of channel erosion and deposition, and the factors controlling these, over a period of several years. Observations reveal differences in the textural and structural character of the deposits, in and around the stream channel in front of the Drummond Glacier and similar deposits located farther downstream. The material close to the ice contains much more poorly sorted and stratified material. Downstream in places, wide alluvial flats occur, and these are composed predominantly of subrounded to rounded stratified and sorted gravels and fines. The presence of poorly stratified and poorly sorted material close to the ice indicates that material of outwash type is not forming in quantity in front of the ice today. This, in turn, suggests that the braided alluvial flats located farther downstream may not be outwash, when the term outwash means proglacial deposits washed out from the ice. Rather the alluvial flats located farther downstream may have been formed by fluvial erosion and deposition some time after ice retreat and some appreciable distance from the ice. Measurements of contemporary erosion and deposition on the alluvial flats, will permit estimations to be made of present day rates of change, and will serve as one kind of check on the idea of "Postglacial" creation of the flats. Mapping of surficial deposits in the valley reveal the predominance of depositional material considered to have been laid down close to melting ice. This ice proximus material gives rise to either hummocky topography or to a non-paired series of benches which parallel the river in places. Throughout the valley there exists a paucity of landforms which can be identified as recessional or end moraines, and also of outwash deposits associated with these. This, combined with the predominance of ice proximus material, indicates that the ice retreated not by a series of stillstands during deglaciation, but rather by stagnation and lowering in place.Item Embargo A Study of the star transition effect under lead(1963) Well, Arnold Daniel; Wilson, Brian G.Item Embargo Permian Spiriferella fron the Yukon Territory(1963) Johnson, Charlie Ernest; Nelson, Samuel J.Item Metadata only An Investigation into the resolution of scintillation counters for low energy gamma radiation(1964) Narayan, G.

DavidAn experiment was performed to determine the effects of chronological age and "extraversion" on reminiscence, using a pursuit rotor task. Three chronological age groups were used: a young adult group (17-25 years ), a middle age group (3 6 - 46 years), and an old group (60-94 years ). From each age group, three subgroups were selected on the basis of scores obtained on the extraversion scale of the Maudsley Personality Inventory (Eys enck, 1959): a high extravert group, a middle extravert group, and a low extravert group. from all three age groups were tested under massed conditions. Young and middle aged Ss were also tested under distributed conditions. Reminiscence was scored by two methods: the method which Eysenck favors, based on the difference between the average of the last three 10-sec. prerest trials and the first 10-sec. postest trial; and the 20-20 method, based on the difference between the last 20 - sec. of prerestand the first 2 0- sec. of postrest practice. Two methods of scoring were used in order to determine whether the results depend specifically up on the method used to compute reminiscence scores. Amount of reminiscence was found to be greatest for the youngest age group regardless of the method of computation used. The age order of size of reminiscence scores obtained by the other two groups varied with the method of computation. No significant differences in amount of reminiscence were found between extraversion subgroups except in the youngest age group. The results are discussed in terms of the Hullian concepts of IR and SIR. It is suggested that as age increases the rate of dissipation of IR decreases and that this affects the development of SIR in different age groups.Item Embargo Sensitivity considerations in electron paramagnetic resonance spectrometers(1964) Dering, John C.; Buckmaster, Harvey A.
