Thermal decomposition and gasification of cellulose and wood wastes
(1980)The thermal decomposition of jack pine bark, white birch sawdust and cellulose has been studied by both isothermal weight-change determinations and dynamic thermogravimetry mostly in inert atmospheres up to 900°C. Gaseous ... -
Aspects of the environmental chemistry of methoxychlor
(1980)Preliminary investigations on the Environmental Chemistry of Methoxychlor [2,2-bis (p - methoxyphenyl)-1,1,1- trichloroethane], a potential DDT replacement, have been conducted with emphasis on its degradation by ... -
Foliage and wood production in 17- and 32- year old Pinus banksiana Lamb. of Northwestern Ontario
(1980)The objectives of this study were 1) to provide information on the above ground biomass production of young jack pine (Pinus banksiana Lamb.) stands, and 2) to evaluate the influence of crown foliage stand density, and ... -
Ecology of northern pike, Esox lucius Linnaeus, in Savanne Lake, Ontario
(1980)Important aspects of the life history and population dynamics of the northern pike, Esox lucius, in Savanne Lake, Ontario were studied during 1977 and 1978. Feeding relationships involving northern pike and walleyes, ... -
Lattice vibrations induced by impurities in polar crystals
(1980)The effect of a single or a pair of polarizable impurities on the vibrational frequencies of a solid is investigated. It is shown that the introduction of impurities alters the energy of the crystal due to the coupling ... -
Bidentate phosphine complexes of copper (I) : their syntheses and interactions with sodium tetrahydroborate and sodium cyanotrihydroborate
(1981)Copper(l) chloride and perchlorate complexes of the types (L~L)CuCl, (L-L)[subscript 3]Cu[subscript2]X[subscript2] (X=Cl-,C10-4), C(L-L)[subscript2]Cu]C10[subscript4] (L-L=DPPM, DPPE, trans VPP, cis VPP, DPPP, DPPB,DPPPe,DPPH) ... -
Reactions of Co(II) with sodium cyanotrihydroborate in the presence of a series of bidentate and some monodentate phosphines
(1981)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 ... -
Stratigraphy of the western Lake St. Joseph greenstone terrain, Northwestern Ontario
(1981)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 ... -
Characterization, distribution and pathogenicity of bacteria isolated from chlorotic white spruce (Picea glauca (Moench) Voss)
(1981)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 ...
