The effect of oxygen on the reaction between copper and saphire

Thomas Edward O’Brien
The effect of oxygen potential on the wetting behavior and interfacial energy between copper and sapphire was studied using the sessile drop technique in a CO-CO₂ atmosphere. A linear relationship was found between γ[sub SL] and log P0₂ from 10⁻⁶ to 10⁻⁵ atmosphere. Beyond 10⁻⁵ atmosphere γ[sub SL] approached a constant value asymptotically. A barrier surface layer was proposed to explain this change. The Gibbs' adsorption equation was used to evaluate the characteristic of the...

Pharmacological blockade of the cardiovascular dive response : effects on heart rate and diving behaviour in the harbour seal (Phoca vitulina)

Nicole M. Elliott
While diving, harbour seals (Phoca vitulina) manage their oxygen stores through cardiovascular adjustments including bradycardia, a concurrent reduction in cardiac output, and peripheral vasoconstriction. At the surface, post-dive tachycardia facilitates rapid reloading of these oxygen stores. Although harbour seals can tolerate over 20 min of submergence, the majority of their natural dives are only 2 to 6 min and are usually followed by surface intervals that are less than 1 min, so they spend about...

Capacity development for local participation in community based natural resource management of Namibia : the #Khoadi //Hôas conservancy experience

Meseret Taye
Namibia’s community based natural resource management program (CBNRM) integrates local participation in rural development and biodiversity conservation. This effort was launched through key legislation that devolved the right to manage wildlife and other renewable resources on communal lands from the state to community level conservancies. Local participation is dependent upon the capacity of the locals to self mobilize and establish conservancies, plan and implement their programs, and monitor and evaluate their progresses and impacts. Accordingly,...

Michael Gurstein
The application of information and communications technology (ICT) to enable and empower community processes, the goal of Community Informatics is to use information communication technologies (ICT) to enable the achievement of community objectives including overcoming “digital divides” both within and between communities. However, community informatics goes beyond discussions of the “Digital Divide” to examine how and under what conditions ICT access can be made usable and useful to the range of excluded populations and communities...

Living well with chronic illness : aligning tensions, attitudes, strategies, and meanings

Susan Lynn Mills
Chronic illnesses have an enormous impact on individuals and society and consume considerable resources. Increasingly, studies have shown that some people have a good life with these long-term conditions despite the economic hardship, pain, suffering, and disability they create. This raises questions about what characterizes these experiences and how they develop in the context of these challenges. In this interpretive study, these issues were explored using the interview data of 27 women and 4 men...

William Peter Donald Goldring
The construction of unsaturated 14-membered lactams 77-92 via ring-closing metathesis (RCM) of a series of diene-amides using Grubbs' benzylidene 3 was examined as part of an ongoing study in our laboratory into the chemistry and formation of macrocyclic compounds. Specifically, nine contiguous sites for ring closure were examined to explore the factors governing the yield and the resulting diastereomeric ratio of the newly formed olefin. The position of the olefin within the lactam products was...

Characterization of 2,3-dihydroxybiphenyl 1,2-dioxygenase, a key enzyme in polychlorinated biphenyls (PCBs) biodegradation

Frederic H. Vaillancourt
2,3-Dihydroxybiphenyl 1,2-dioxygenase (DHBD[sub LB400], EC from Burkholderia sp. LB400, the extradiol dioxygenase of the biphenyl biodegradation pathway, was investigated using a highly active, anaerobically purified preparation of enzyme. The steady-state kinetic data obtained using 2,3-dihydroxybiphenyl (DHB) fit a compulsoryorder ternary-complex mechanism in which substrate inhibition occurs. DHBD[sub LB400] was also stabilized by small organic molecules. The molecules that stabilized DHBD[sub LB400] most effectively also inhibited the cleavage reaction most strongly. DHBD[sub LB400] was subject...

Novels and the poetry of Philip Larkin.

Joan Sheila Mayne
Philip Larkin has been considered primarily in terms of his contribution to the Movement of the Fifties; this thesis considers Larkin as an artist in his own right. His novels, Jill and A Girl in Winter, and his first volume of poetry, The North Ship, have received very little critical attention. Larkin's last two volumes of poetry, The Less Deceived and The Whitsun Weddings, have been considered as two very similar works with little or...

Non-intentional performance practice in John Cage's Solo for Sliding Trombone

James Gregory Chilton
This dissertation provides a study guide to aid trombonists in understanding and appreciating the Solo for Sliding Trombone (1957-58), one of the many solo parts from the Concert for Piano and Orchestra (1957-58) by John Cage (1912-1992). This seldom-performed piece of contemporary music is often misunderstood and is overlooked as an important part of the trombone repertoire. This document aims to help trombonists seeking to perform unaccompanied trombone music to develop an understanding of Cage's...

Integrating discrete-return scanning LiDAR and spaceborne RADAR to support aboveground biomass assessments

Olivier W. L. Tsui
Forests are considered important reservoirs of organic carbon and have been identified as essential in moderating climate change. Measuring the amount of carbon stored in forests helps improve our understanding of the carbon budget and help with climate change adaptation strategies. Therefore, effective and accurate methods in characterizing changing forest cover and biomass densities are needed. Both LiDAR (light detection and ranging) and radar (radio detection and ranging) technologies can contribute towards the study of...

Effect of fibre reinforcement on the crack propagation in concrete

Anthony Sze-Tong Yam
The influence of fibre reinforcement on crack propagation in concrete was studied. Thirty-five double torsion specimens, made with three types of fibres (fibreglass, straight steel fibres and deformed steel fibres) were tested. The variables were the fibre volume and size of the fibres. The test results indicated that the resistance to rapid crack growth increased somewhat with increasing fibre content up to about 1.25% - 1.5% by volume. The degree of compaction had an enormous...

National transport policy in Canada : the case of rail transport

Verna Semotuk
National transport policy should be determined by choosing among existing policy and alternatives to it on the basis of national and regional development objectives. This approach to transport policy formulation is explored within one important transport sector: high-bulk, long-haul freight in Western Canada. The implications of national rail policy are most pertinent, and most keenly felt, in economic regions dependent upon the export of primary resources, and it is in these markets which rail displays...
