Intramolecular carbenoid insertion : reactions of [alpha] -diazoketones derived from benzothienyl, pyrolyl and indolyl alkanoic acids with rhodium (II) acetate
(Brock University, 1999-07-09)
Recent studies have shown that the rhodium (II) acetate decomposition chemistry observed for a-diazoketones tethered to thienyl, furanyl, and benzofuranyl moieties is dependent not only on the nature of the heteroatom ...
An experimental investigation of dechanneling in copper single crystals
(Brock University, 1984-07-09)
This investigation comprises a comparison of experimental and theoretical dechanneling of MeV protons in copper single crystals. Dechanneling results when an ion's transverse energy increases to the value where the ion ...
Properties of NaxCoO2 /
(Brock University, 2005-06-29)
Polycrysttdline samples of NaiCoOa were prepared using the "Rapid heat-up" method. One set of samples was annealed in flowing O2, while the other set in flowing Argon. X-Ray diffraction measurements indicated a stable ...
Optical properties of organic superconductor K-(BETS)2FeBr4 /
(Brock University, 2007-06-04)
/c-(BETS)2FeBr4 is the first antiferromagnetic organic superconductor with successive antiferromagnetic and superconducting transitions at Ta^=2.5K and Tc=l.lK respectively at ambient pressure. Polarized reflectance ...
Synthesis and spectral studies of methyl heterocylic systems
(Brock University, 1979-07-09)
2-Carboxy-2?-methyldiphenyl sulfide was prepared by the Ullmann reaction and cyclodehydrated by sulfuric acid to afford 4-methylthioxanthone. 1-Methylthioxanthone was separated from the reaction mixture obtained upon ...
Mating behaviours of the field cricket (Gryllus integer) at different levels of male density
(Brock University, 1982-07-09)
The reproductive behaviour of the field cricket, Gryllus integer, was systematically observed in indoor arenas to determine the extent of female Choice and male-male competition at different sex ratios representing two ...
Deviance of syntax in oral languages and oral reading behavior
(Brock University, 1980-07-09)
The major hypothesis of this paper is that any deviance in syntax present in oral language will be evident in oral r eading behaviour. Using Lee and Canter's Developmental i 1 Sentence Scoring technique (1971) and Y. ...
Transcendental phenomenology : a response to psychologism
(Brock University, 1978-07-09)
Graffiti, memory and contested space : mnemonic initiatives following trauma and/or repression in Buenos Aires, Argentina
(Brock University, 2007-05-21)
Graffiti, Memory and Contested Space: Mnemonic Initiatives Following Periods of Trauma and/or Repression in Buenos Aires, Argentina This thesis concerns the popular articulation ofmemory following periods or incidents ...
An analysis of students' travel motivations and images of China as a tourist destination
(Brock University, 2004-07-14)
Despite China's rapid growth in inbound tourism, the nature of its Canadian tourist market has been insufficiently studied. In response to this need, the objectives of this study are to identify China's destination image ...
