Several genera of bacteria were isolated from the foliage, twigs, bark and wood of stems of chlorotic 10 - 12 years old white spruce (Picea glauca (Moench) Voss). Most of the isolates were nonspore-forming, aerobic ...

The reactions between Co(C10[subscript4])[subscript2].6H[subscript2]O or CoCl[subscript2].6H[subscript2]O, NaBH[subscript3]CN and some monodentate (PPh[subscript3] and Pcy[subscript3]) and a series of bidentate phosphines ...

Uniroyal PA0-20E, an oligomer of 1-octene, is a dielectric fluid proposed as a replacement for polychlorinated biphenyls. No studies on its biodegradation have been reported in the literature to date. This thesis ...

This thesis is concerned with the studies in the synthesis of a monoterpenoid alkaloid, chaksine. Ethyl 2-n~butyl-4-bromoacetoacetate (11) was treated with sodium azide to give ethyl 2-n-butyl-4-azidoacetoacetate (12), ...

The objectives were: to review the successional behaviour of white spruce (Picea glauca (Moench) Voss) - trembling aspen (Populus tremuloides Michxt) stands in the literature, to conduct field studies of the successional ...

The development of the crown structure of Pinus resinosa Ait. was analysed in terms of three component processes of tree growth: the number of first order branches per whorl within the crown, the annual extension increments ...

The sorption of ammonia was studied at 273 and 298 K on Californian and Quebec chrysotile heat-treated at 150, 300, 500 and 700 degrees C. Another ammonia sorption study involving the two chrysotiles treated at 500 ...

To evaluate the importance of phenology and strobilus production in a clonal seed orchard of white and black spruce, 14 clones of each species represented by 4 ramets each, were selected from the Mattawin seed orchard. ...

The western Lake St. Joseph area in Northwestern Ontario is underlain by Archean metavolcanic and metasedimentary rocks. The strata, referred to as the Lake St. Joseph Group comprise three formations representative of ...
