An investigation of ethylene inhibition of growth in etiolated Avena sativa coleoptiles /
(Brock University, 1975-06-09)Growth rates of etiolated Avena sativa coleoptiles in pH 7.0 buffered medium are stimulated in a synergistic manner by IAA and 320 ~l/l carbon dioxide. The suggestion that carbon dioxide stimulated growth involves dark ... -
Investigation of Frustrated Quasi-One-Dimensional Quantum Spin-Chain Materials
Copper arsenite CuAs2O4 and Copper antimonite CuSb2O4 are S=1/2 (Cu2+ 3d9 electronic configuration) quasi-one-dimensional quantum spin-chain compounds. Both compounds crystallize with tetragonal structures containing ... -
An investigation of geological and geochemical characteristics of late-Quaternay sediments in the Georgian Bay Region, Southern Ontario
(Brock University, 1980-07-09)Core samples of postglacial sediments and sediment surface samples from Shepherd Lake on the Bruce Peninsula, Harts Lake on the Canadian Shield, and two cores from Georgian Bay (core P-l in the western deep part and ... -
An investigation of individual differences in diffusion of attention and the attentional blink
(Brock University, 2010-03-09) -
Investigation of molecular polarizabilities and derivatives in halomethanes
(Brock University, 1993-07-09)The research undertaken was to obtain absolute Raman intensities for the symmetric stretching vibrations of the methyl halides, CH3X with (X=F, CI, Br), by experiment and theory. The intensities were experimentally ... -
Investigation of motivation strategies used by school teachers for workplace engagement
(Brock University, 2011-10-14)The purpose of this study was to explore the strategies that elementary school teachers use to be engaged in their work. Participation was solicited from a random sample of schools stratified by location (i.e., ... -
Investigation of regio- and sterochemistries of microbial biotransformation /
(Brock University, 1997-05-21)Epoxides can be hydrolyzed by fungi to produce chiral diols. The first part of this thesis presents an investigation of the microbial hydrolysis of aziridines comparable in structure to epoxide biotransformation substrates. ... -
Investigation of single tryptophan proteins encapsulated in TEOS-derived sol-gel matrices by fluorescence spectroscopy /
(Brock University, 1997-05-21)In the work reported here, optically clear, ultrathin TEOS derived sol-gel slides which were suitable for studies of tryptophan (Trp) fluorescence from entrapped proteins were prepared by the sol-gel technique and ... -
An investigation of sugar feeding by black flies (Diptera: Simuliidae)
(Brock University, 1995-07-09)Although much research has been conducted on blood-meal acquisition in adult female black flies (Diptera: Simuliidae), the same cannot be said for sugarmeals. Both sexes feed on sugar which provides energy for flight and ... -
Investigation of the Biological Effects of Rosemary (Rosmarinus Officinalis L.) Extract in Human Lung Cancer Cells
Cancer cells display enhanced growth rates and a resistance to apoptosis. Lung cancer accounts for the most cancer related deaths and non-small cell lung cancer (NSCLC) represents an aggressive form of lung cancer, accounting ... -
Investigation of the composition of linear alkylbenzenes with emphasis on the identification and quantitation of some trace compounds using GS/MS system in both electron impact and chemical ionization modes
(Brock University, 1994-07-09)Linear alkylbenzenes, LAB, formed by the Alel3 or HF catalyzed alkylation of benzene are common raw materials for surfactant manufacture. Normally they are sulphonated using S03 or oleum to give the corresponding linear ... -
An investigation of the emotion assumptions of just-world theory /
(Brock University, 2006-05-19)The purpose ofthis study was to investigate the emotion assumptions underlying just-world theory. This theory proposes that people have a need to believe in a just world - a world where people get what they deserve. The ... -
Investigation of the Expression of Glucose Transporter Proteins in Human Cancer Cells
(Brock University, 2012-08-15)Cancer cells are known to display increased glucose uptake and consumption. The glucose transporter (GLUT) proteins facilitate glucose uptake, however, their exact role in cancer metabolism remains unclear. The present ... -
Investigation of the mechanism of transfer of a-tocopherol by the human a-tocopherol transfer protein (H-a-TTP) /
(Brock University, 2007-06-01)The human a-tocopherol transfer protein (h-a-TTP) is understood to be the entity responsible for the specific retention of a-tocopherol (a-toc) in human tissues over all other forms of vitamin E obtained from the diet. ... -
An investigation of the nature and role of historicality in the thought of Dilthey and Heidegger
(Brock University, 1996-07-09)Introduction The question of the meaning, methods and philosophical manifestations of history is currently rife with contention. The problem that I will address in an exposition of the thought of Wilhelm Dilthey and ... -
An investigation of the psychopathy construct and its (novel) correlates in non-clinical samples
(Brock University, 2011-05-17)A substantial research literature exists regarding the psychopathy construct in forensic populations, but more recently, the construct has been extended to non-clinical populations. The purpose of the present ... -
The investigation of the reduction mechanism of the 5a-reductase enzyme of Penicillium decumbens /
(Brock University, 1990-05-21)The 5a-reductase of Penicillium decumbens ATCC 10436 was used as a model for the mammalian enzyme to investigate the mechanism of reduction of testosterone to 5adihydrotestosterone . The purpose of this study was to ... -
