synthetic studies on slaframine
(1980)thjs thesis is concerned with the preliminary studies in the synthesis of an indolizine alkaloid, slaframine. a wittig reaction of 3-carbethoxypropyltriphenylphosophonium iodide (43) with 4-pentenal (44) gave ... -
migration and development of cystidicola spp. (habronematoidea) in their definitive hosts and the population biology of c. cristivomeri white, 1941 in salvelinus spp.
(1980)the development of cystidicola cristivomeri in lake trout, salvelinus namaycush, and c, farionis in rainbow trout, salmo gairdneri, is described. the population biology of c. cristivomeri was investigated in lake trout ... -
molecular and intramolecular relaxation processes of small molecules
(1980)the dielectric relaxation method was used to determine the activation parameters of some ethane derivatives and simple amides. a general radio 1615-a capacitance bridge was utilized to obtain the energy barriers of the ... -
pressure dependent extrinsic effects in insb
(1980)electrical transport properties of n and p-type insb in the temperature range 6.2-300k have been studied under pressures up to 15 kbar using hall measurements. the donor gap in n-insb is found to increase linearly with ... -
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 ... -
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, ... -
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 ... -
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) ...
