effects of depressed ph on survival, growth and reproduction of brook trout, salvelinus fontinalis (mitchill)
(1977)brook trout were continuously exposed to depressed ph values from 4.0 to 6.0, at 0.5 unit intervals during a nine-month partial-chronic bloassay. at all ph levels above 4.0, juvenile fish exhibited greater than 96 per ... -
reactions of sodium tetrahydroborate with metal ions in the presence of nitrogen donor ligands
(1977, c197)the work described in this thesis is part of an ongoing effort in these laboratories to determine in more detail how a variety of factors, particularly the nature of added ligands, affects the type of products and the ... -
dielectric studies of molecular and intramolecular motions in polystryrene matrices
(1977)dielectric absorption studies of a variety of polar solutes containing rotatable groups and of some analogous rigid molecules dispersed in atactic polystyrene have been carried out. preparation of the solutions as solid ... -
relaxation processes in polystyrene matrices
(1977)dielectric absorption of aromatic and aliphatic molecules containing the rotatable substituent group and of some analogous rigid molecules in $olutions of polar solutes dispersed in an atactic polystyrene matrix are ... -
effects of concentric and eccentric contractions on strength, retention and bilateral transfer
(1978)the purpose of this study was to examine the effects of two different strength training methods, (concentric and eccentric) on strength, retention and bilateral transfer. subjects were 22 male volunteers, aged 16 to 17. ... -
transforming ordinary linear differential equations to constant coefficient differential equations
(1978)the main purpose of this thesis is to give a characterization of nth order linear homogeneous differential equations that can be transformed into constant coefficient differential equations. the characterization given ... -
studies of the biology of swim bladder nematodes, cystidicola spp. (habronematoidea)
(1978)the life cycle and larval development of swim bladder nematodes, cystidicola spp., have been elucidated. c, farionis developed in three species of amphipod. naturally infected amphipods have been found previously but one ... -
hydrostatic pressure effect on the gunn threshold electric effect in n-insb
(1978)the gunn effect as a function of pressure has been studied in n~type insb. the gunn threshold field is found to decrease with increasing pressure reaching a minimum at p ~ 9 kbars. it then increases while the oscillations ... -
hall effect investigations in n-insb under pressure
(1978)low field electrical transport properties of n-insb in the temperature range 6.4k-300k have been studied under pressures up to 15 kbar using hall measurements. the pressure dependence of the carrier concentration, the ... -
effects of various leg positions at the catch on the force of the rowing stroke
(1978)the purpose of this thesis was to test in isolation various leg and body movements in the rowing action and to relate them to forces created on the oar handle. the subjects were four senior oarsmen. the independent ...
