A Sigh of Mystery: Karl Barth's Theology of the Virgin Birth
In this study, I examine Karl Barth's doctrine of the virgin birth of Christ in relation to his discussions in the Church Dogmatics of Christology, pneumatology and interpretation of Scripture. I argue that the virgin birth of Jesus Christ is understood by Barth as a fitting sign to expresses the form of the dialectic of God's "No" to sin and "Yes" to humanity in his free act of revelation a...
Archean Crustal Evolution in the Barberton Mountain Land, South Africa: U-Pb and Nd Isotopic Constraints
New U-Pb ages from the Barberton Mountain Land document an 800 m.y. period of Archean magmatism (ca. 3540 Ma to ca. 2740 Ma) that can be divided into five distinct episodes. Magmatic activity during Episode I includes tonalite-trondhjemite gneisses such as the Steynsdorp pluton (3509 +8/-7 Ma) and a tectonically interleaved sliver (3538 +4/-2 Ma) located at the base of the Onverwacht Group....
Fluorescently Labeled Sodium Hyaluronate: Synthesis, Characterization and Solution Properties
Fluorescence spectroscopy has been proven to be a useful technique for the investigation of the structural, physical and solution properties of polymers. A polymer system containing a photo physical probe can be investigated using fluorescence quenching and polarization. We have randomly labeled sodium hyaluronate (HA) chains with fluorescent dyes such as 1-(1-pyrenyl)methyl amine and N-ε-d...
The Provocations of Nihilism: Practical Philosophy and Aesthetics in Jacobi, Kant, and Schelling
The purpose of the dissertation is to describe how Friedrich Heinrich Jacobi's diagnosis
of nihilism at the heart of the rationalist metaphysics of the Enlightenment provokes a
tum to practical philosophy and aesthetics as alternative areas of philosophical scrutiny. I
divide my analysis into two basic parts, treating practical philosophy and aesthetics
respectively. The first part argu...
A New Procedure for Specific Cutting Force Assessment in High-Speed End Milling
High-speed machining (HSM) concepts were developed in response to productivity,
quality and cost concerns. Significant advancements in controls and machining technologies
have recently come together to enable the wide spread use of HSM on the
plant floor. However, with the advancement of HSM technology, dynamic problems
associated with modern machine-tool structures have not been fully ...
Alkyne-Cobalt-Clusters: Syntheses, Structures and Rearrangements of Metal-Stabilized Propargyl Cations and Radicals
Cobalt-clusters are versatile reagents in organometallic chemistry. Their ability to protect an alkyne allows one to selectively manipulate a ligand without undergoing a competitive reaction from the alkyne. Cobalt-clusters geometrically modify linear alkynes to 136-145° degrees, thereby allowing for some non-traditional alkynyl chemistry to occur. In particular, the focus of this dissertat...
Fractures and Fracture Filling in the Guelph Formation, Steetley Quarry Flamborough, Ontario
The North Quarry (north of Ontario Highway 4) is located in Flamborough Ontario. In it, rocks of the Guelph formation are well exposed. The Guelph formation consists of dolomite and at the North Quarry has an average thickness of 30m. These rocks are cut by three predominant joint sets which have no indication of shear motion. The 030° set was formed as a result of compaction and loading; I...
Early Proterozoic Evolution of the Grenville Belt: Evidence from Neodymium Isotopic Mapping, North Bay Ontario
Detailed Nd isotopic mapping in the southwestern
Grenville Province between North Bay, Ontario, and
Temiscaming, Quebec has revealed the precise trend of the
proposed Penokean-aged suture discovered during reconnaissance
isotopic mapping by Dickin and McNutt (1989).
Lithotectonic domains proposed by Easton (1989} for the
greater North Bay area are cross-cut by the suture. As
The Synthesis of [16,17-^14C]Geranylgeranyl Pyrophosphate as a Probe for The Biosynthesis of Taxol
Taxol, a highly functionalized and complex diterpene belonging to the taxane
group, possesses strong antitumor activity against various cancers, especially in cases of
advanced ovarian and breast cancers. Because of the unique mechanism of action and the
unusual chemical structure, taxol may represent the prototype of a new class of
chemotherapeutic agents. The non-clinical work up to d...
The Evolution of the Grenville Province in the Mattawa Region of Ontario: Evidence from Neodymium and Constraints from Aeromagnetic Data
Approximately eighty new neodymium model ages were determined on grey
orthogneisses in the Mattawa region of Ontario and were used to develop a Grenvillian
tectonic model in the region. A residual-magnetic field map developed from
aeromagnetic data provides an additional constraint on the terranes mapped based on Nd-model
ages. The field area was divided into three sections: the norther...
A Hopeful Demise: A Biblical and Practical Theology of Exile for the Canadian Church Today
This dissertation is an attempt to apply the motif of exile to the church in Canada today
and employ biblical resources to guide the church in its engagement with Canadian culture. At
one time the church held a place at the centre of Canadian life and contributed to the formation of national culture. As the nation has evolved, the role of the church has shifted significantly. The advent o...
The Form and Extent of the Grenville Front Tectonic Zone in Proximity to Coniston, Ontario as Defined by Aeromagnetic and Paleomagnetic Studies of the Sudbury Olivine Diabase Dikes.
Geophysical studies of the northwest trending Sudbury olivine
diabase dikes, to the south of Coniston, Ontario establish a
deformation zone, within the Southern province up to 10 km from the
Grenville Front. Paleomagnetics reveal two directional groups

Pb isotope systematics in Cenozoic igenous rocks from the Rio Grande Rift region, USA
The Rio Grande Rift is a major tectonomagmatic feature of the North
American craton. Physiographically, the present rift is recognized as a series of grabens
and half-grabens which extend for over 1000 km from south-central Colorado into
Chihuahua, Mexico. Rift structures, however, are recognized as far north as the
Colorado-Wyoming border. Basaltic magmatism within the rift began by 30...
