abstract: Title: Petrology and Geochemistry of a Small Greisen Zone in Southwestern New Brunswick, Author: James A. Michaelis, Location: Thode

abstract:
A peripheral flourine-rich zone of a small post-techtoonic adamellite stock located in southwestern New Brunswick is examined. This apogranite zone contains aplite dykes, small pegmatite, quartz-flourite and greisen veins. Endogenetic alkali metasomatic modification of an originally porphyritic adamellite has resulted in the intracrystalline replacement of groundmass and plagioclase by large orthoclase perthite and quartz porphyroblasts. Low K/Rb and Ba/Rb ratios indicate this zone has favourable potential for mineralization resulting from residual fluids.

Fracture controlled greisenization shows complete replacement of feldspars by quartz-sericite aggregates. Variations in sodium content of the greisen in indicative of pH conditions of post-magmatic fluids. Early stages show strong leaching of sodium by acidic fluids. Mineralization associated with these types of greisens is minimal. Later stage tin rise greisens have associated albitization overprinting the physic assemblage representing increasing pH conditions of the fluids.

The greisen zone is interpreted to be either adjacent to or below any possible zone of potential tin mineralization. Another possibility is the post-magmatic fluid phase was too small for significant development of later state greisens.

title: Analyses and Cost Evaluation of Code Tree Search Algorithms

Anderson, J. B.

subject: analyses, cost evaluation, code tree, search, algorithms, branches

abstract:
 Codes with a tree structure find wide use in data compression and error correction. It is generally impractical to view and weigh all the branches in a code tree, so a search algorithm is employed which considers some but not others in a predetermined fashion. Traditionally, the efficiency of code tree search algorithms has been measured by the number of tree branches visited for a given level of performance. This measure does not indicate the true consumption of resources. Cost functions are defined based on the number of code tree paths retained, S, the length of the paths, L, and the number of code tree branches searched per branch released as output, E[C]. Using these cost functions, most of the existing algorithms as well as some new algorithms proposed here are compared.

 These new algorithms include three metric-first algorithms. The first one, the merge algorithm, uses, in addition to the main list used by the stack algorithm, an auxiliary list to store paths. The merge algorithm reduces the dependence on S for the product resource cost from O(S^2) for the stack algorithm to O(S^4/3 ) for the merge algorithm. A generalization of this algorithm reduces the product cost to O(S log S). The second algorithm uses a class of height-balanced trees, known as AVL trees, to store code tree paths, resulting in an alternate method to the merge algorithm achieving O(S log S) cost.

 The third algorithm, using the concepts of dynamic hashing and trie searching, provides important modifications to the Jelinek bucket algorithm by incorporating dynamic splitting and merging of buckets. This strategy provides a
balanced data structure and reduces the product cost still further compared to the first two algorithms.

 We next turn to analysis of the number of nodes visited during a search. Using the theory of multitype branching processes in random environments an equation for node computation is derived for asymmetric source coding by the single stack algorithm. This equation is shown to be the stochastic analog of an equation for symmetric sources. Simulation results, obtained by encoding the Hamming source by the single stack algorithm, are used to optimize the performance of the algorithm with respect to the bias
factor, stack length, and limit on computation. A modification to the algorithm that raises the barrier during forward motion provides a better distortion performance.

 The metric-first stack algorithm is used to encode a voiced speech sound. From experimental evidence, it is shown how to optimize the algorithm's SNR performance with respect to the algorithm's storage, execution time, and node computation. For each of these, the optimal parameterizing
of the algorithm differs markedly. Similarities are pointed out between the results for speech and earlier theoretical results for the binary i.i.d. source with Hamming distortion measure. It is shown that metric-first algorithms may perform better with "real life" sources like speech than they do with artificial sources, and in view of this the algorithms proposed here take on added significance.

A range of locator variables is identified from the literature and interviews. Four variables are then selected from this range and utilised in a multiple regression analysis in an effort to explain the occurrence of multiple occupancy residential structures in terms of their spatial relationships with the selected variables .

abstract:
This thesis describes an experimental study of external
boundary layers formed on a flat plate model immersed in dilute
homoqeneous polymer solutions.

The model was subjected to flows of homoqeneous aqueous
polyacrylamide solutions with a free stream velocity of 2.21 feet per
second.

Variations in the drag force with respsct to solution
concentration were assessed from extensive velocity profile data and
direct drag measurements. For the flow conditions a maximum reduction
in total drag of 33 per cent occurred for a concentration of 50 wppm.
Profile drag, as well as viscous drag, is apparently reduced in dilute
polymer solutions. For the polymer used, a critical wall shear stress
of 0.011lbf/ft.^2 was found below which no reduction in viscous drag
occurs.

abstract:
 The cryoscopic constant for fluorosulphuric acid has been determined and the nature and concentration of the impurities in the solvent have been investigated.

 The NMR and Gouy methods have been used to determine the magnetic susceptibility of solutions of iodine fluorosulphates. The NMR method has been shown to lead to spurious results.

 Cryoscopy, conductivity and UV and visual spectrophotometry have been used to elucidate the state of iodine fluorosulphates in fluorosulphuric acid. Solutions of stoichiometry corresponding to fifth-, third-, half-, uni-, tri-, and hepta-valent iodine have been investigated. The highest valence state observed was that of iodine trifluorosulphate which
has been shown to be an acid in fluorosulphuric acid. Measurements on fifth- and third-valent iodine solutions indicate that I5+ and I3+ are formed. Measurements on half- and univalent iodine solutions suggest that I2+ is formed. The observed magnetic moment of this species agrees well with that required by theory, 2.0 BM.

abstract:
Thick-film dielectric compositions which devitrify
in a controlled way to form a ceramic phase during processing,
are available for evaluation as crossover insulation in
multilayer circuits. Their advantage over compositions based
upon a borosilicate glass is that they provide a surface of
greater mechanical stability for successive conductor layers
during subsequent firing processes. This results in close
alignment being maintained between successive layers of a
multilayer circuit.

A substantial part of the total manufacturing cost of
a thick-film circuit is associated with the noble-metal
content of conductor compositions. This has given impetus to
the development of Platinum-Silver based pastes in preference
to those containing higher percentages of Gold and Palladium.
The results of an evaluation of dielectric behaviour using
Platinum-Gold electrodes are of little significance if the
intention is to use that same dielectric with Platinum-Silver
electrodes in production. The interaction of materials at the
interfaces during processing is known to alter the properties
of the dielectric quite significantly, and the crossover
structure must be evaluated as a system if useful data is to
be obtained.

This project is an evaluation of two multilayer
systems based upon proprietary pastes from two different
manufacturers; the dielectric is of the glass-ceramic type
and the conductor is based upon a Platinum-Silver composition.
Although claims are made in the product literature that both
systems have equivalent performance, this report will show
substantial differences exist when tests are conducted under
the kind of conditions experienced during production.

abstract:
 The crystal structures of VOP2SiO8, VO(PO3)2, V(PO3)3, (VO)2P2O7 and VAsO5 have been determined with the help of x-rays, and are compared with the known structures in the V-P-As-O system. All the vanadium atoms in the mixed oxides are octahedrally coordinated and the V^+4 O6 and V^+5 O6 octahedra are all characterized by one short vanadyl bond. V^+3 O6 groups are nearly regular. The tetrahedral phosphorus is found in structural elements ranging from infinite metaphosphate chains (V(PO3)3, VO(PO3)2), to pyrophosphate groups ((VO)2P2O7) to isolated tetrahedra (VAsO5 and VOP2SiO8). Both structural and substitutional disordering is evident in the V-P-As-O system, and is discussed together with a detailed model for stacking faults in VAsO5.

 Some of the phases in the V-P-As-O system are known to catalyze the oxidation of butene to maleic anhydride, and certain structural features of the compounds are related to this catalytic activity. α-VPO5 can be
related to (VO)2P2O7 through the formation of shears in a manner similar to shear formation in V2O5, and such a mechanism is proposed as a means whereby an α-VPO5 catalyst can change into (VO)2P2O7, the known composition of the spent catalyst.

Endowment Effect

abstract:
Hoarding is characterized by (a) the persistent difficulty discarding personal items; (b) clutter that interferes with living areas; and (c) significant distress or functional impairment. Hoarding symptoms often emerge in childhood and adolescence, yet very few studies on hoarding in this age group exist. Current models of hoarding emphasize impairments in decision-making, yet the literature on decision-making processes in hoarding presents inconsistent findings. Preliminary cognitive studies in adults suggest that hoarding may be associated with deficits in value attribution (the tendency to assign value to personal items). Thus, we propose that the Endowment Effect (EE), in which ownership of an item increases its perceived value, may be informative for the study of hoarding symptoms.  This study investigated the EE in youth (children and adolescents) with Obsessive-Compulsive Disorder (OCD) and hoarding symptoms. Given that hoarding involves significant difficulty discarding personal items, we hypothesized that hoarding in youth is associated with a higher EE.
Thirty youth participants with a confirmed DSM-5 diagnosis of OCD completed the Endowment Task, a game script of the EE; the Wisconsin Card Sorting Test (WCST), a test of cognitive flexibility; and the Balloon-Analogue Risk Task (BART), a test of risky decision-making. The Children’s Saving Inventory-Parent Version (CSI) was used to measure severity of hoarding symptoms. We divided our sample into thirds based on CSI scores to create a ‘High Hoarding’ group (HH; n=12; mean CSI (S.D.)=30.83 (5.47446)) and a ‘Low Hoarding’ group (LH; n=10; mean CSI (S.D.)=5.00 (3.16228)). The HH group demonstrated a higher average EE than the LH group (average EE, 3.22 and 1.59, respectively). In contrast, no significant between-group differences were found on the WCST and the BART (t=0.901, p=0.378 and t=0.338, p=0.739, respectively). The results of this thesis suggest that psychological ownership plays an important role in the manifestation of hoarding symptoms. Thus, we propose that hoarding might be associated with a specific decision-making deficit related to personal possessions.

subject: King Hezekiah, 2 Kings, Isaiah, 2 Chronicles, three portrayals, biblical, faithfulness, political, religious, Lord

abstract: Hezekiah is portrayed as a pious and faithful king in three biblical accounts: 2 Kgs 18-20, Isa 36-39 and 2 Chr 29-32. The way Hezekiah is characterized, however, is quite different in each of these three biblical accounts. Utilizing narrative analysis, this dissertation concentrated specifically on the characterization of Hezekiah in the literary context of these three biblical accounts. Hezekiah's story was examined first as a discrete account applying narrative features separately and then as a story within the larger context of each book. Then, the portrayal of Hezekiah in the three biblical books was compared in conclusion. This dissertation demonstrated that these three biblical accounts relate the same reign of King Hezekiah in their unique way according to their purpose and their individual point of view. The Kings account focuses on Hezekiah's political events including his negative aspects in order to show the faithfulness of the LORD in His promise to David (2 Sam 7) through Hezekiah's faithful actions to the LORD. Hezekiah is portrayed as a round character whose characterization is developed within the story. In Isaiah, the Hezekiah story is reshaped by the narrator by omitting and inserting some parts of Hezekiah's narratives in the Kings account. Hezekiah is portrayed as a more faithful king than his father, Ahaz, in order to encourage the people who heard the visions of Isaiah, to trust in the LORD sincerely. In Chronicles, the Hezekiah narratives are related differently by expanding, abridging, and rephrasing his Vorlage. The Chronicles account depicts Hezekiah as the best king among the Davidic kings in order to indicate the beginning of the reunited kingdom. Thus, the Chronicles account fully expands Hezekiah's religious reforms and abridges his political events in order to portray him as a second David and Solomon. In the three accounts, Hezekiah is not portrayed as a perfect king, but instead as a limited human king in order to encourage the readers to see the LORD, the heavenly King.

Chromatin remodelling
Histone acetylation
Valproic acid
HDAC inhibition
Melatonin MT1 receptor promoter

abstract:
Melatonin is an indoleamine hormone with neuromodulatory and neuroprotective properties. It mediates many of its effects by its two G protein-coupled receptors, MT1 and MT2. We have shown that valproic acid (VPA) induces melatonin receptor expression in cultured rat C6 glioma cells, and in the rat hippocampus. VPA is known to affect gene expression through several mechanisms, including the modulation of intracellular kinase pathways and/or transcription factors, as well as the inhibition of histone deacetylase (HDAC) activity. In this study, we show that HDAC inhibitors of distinct chemical classifications, including suberanilohydroxamic acid (SAHA) and 4-(dimethylamino)-n-[7-(hydroxyamino)-7-oxoheptyl] benzamide (M344), parallel the effects of VPA on MT1 induction in vitro. However valpromide, a VPA analogue that lacks the ability to inhibit HDAC activity, does not. The observed increase in MT1 expression by VPA is matched by an increase in global histone H3 acetylation. More importantly, an enrichment of histone H3 acetylation occurs along the rat MT1 promoter following treatment with VPA, indicating that histone acetylation and chromatin remodelling are a primary mechanism underlying this induction. Independent of VPA, the rat MT1 gene may be regulated by a number of intracellular kinase pathways and transcription factors, which are also targeted by VPA. KG501-mediated CREB inhibition did not block MT1 upregulation by VPA. Blockade experiments targeting the PKC, PI3K/AKT, or GSK3β signaling pathways suggest that VPA induces melatonin receptor expression independent of these intracellular signaling cascades as well. The relevance of melatonin receptor upregulation was assessed using in vivo VPA and melatonin combination treatments on neuroprotective gene expression.
The results of this study provide evidence that expression of the melatonin receptor is epigenetically induced by VPA by means of promoter histone acetylation. Melatonin receptor upregulation by VPA, or other HDAC inhibitors, may represent a therapeutic strategy for the management of several nervous system disorders.

abstract:
 The purpose of this research is to determine how the changing levels of technology at Dofasco Inc. have affected its labour force. This will be approached from the perspective of a production function. An overview of Dofasco's history quickly reveals that the level of technology in its factory is definitely growing. This fact is reflected in the large quantities of new equipment purchased in the company's past.

 The production function is utilized through a graphical interpretation of four ratios: the sales/labour; sales/output; output/labour; and capital/labour. These ratios provide an explanation of when, why, and how the technology level at Dofasco changes and the affect these will have on labour.

 The company successfully raises the value and quality of its output through value adding processing of the raw steel. This is attained by large capital expenditures on new equipment. The new equipment also has the effect of increasing labour productivity. Translating into a declining need for labour inputs. The exacting specifications needed in steel making are now satisfied through the use of computers and not through an experienced workers judgement.

The optical constants, i.e., refractive index n and extinction coefficient k for these materials have been determined and their variation with temperature has been studied using ellipsometric technique. It has been shown that nickel oxide (NiO) is the more predominant phase in the oxides formed on these materials. It has also been found that within experimental error, the water vapour does not play a vital role in the oxidation process.

abstract:
Background: Hemophilia A is X-linked recessive congenital bleeding disorder. Exogenous infusion of FVIII is the treatment of choice in hemophilia A patients. However, inhibitor development remains the major problem in management of Hemophilia A. It has been showed that IVIG has immunomodulatory effects and it has been being used in the treatment of several autoimmune and inflammatory disorders. Here, we investigated the effect of co-administration of FVIII with IVIG on the development of inhibitor in naive and previously immunized hemophilia A mice.
Methods: Initially, hemophiliac mice were immunized by weekly intraperitoneal injection of human recombinant FVIII (rFVIII). The mice then were treated, either by rFVIII/IVIG co-injection or rFVIII alone. In the other experimental group, naive hemophiliac mice were treated with rFVIII/IVIG co-injection for four weeks followed by injection of either rFVIII or rFVIII/IVIG. Plasma's anti-FVIII Ab titer was measured using ELISA.
Results: Weekly injection of rFVIII led to the development of anti-FVIII Ab in all previously untreated mice. Treatment of those immunized mice with rFVIII/IVIG co-injection did not reduce the level of pre-existing Ab. On the other hand, naive mice treated with rFVIII/IVIG co-injection showed significantly less Ab titer compared to the mice received rFVIII alone after 4 weeks (mean Ab titre of 1 compared to 39, in rFVIII/IVIG co-injection and rFVIII groups respectively). Although the rFVIII/IVIG-treated mice developed immune response following the injection of rFVIII alone, Ab titer in those that kept receiving rFVIII/IVIG co-injection remained lower compared to other groups during the whole twelve weeks of the experiment.
Conclusions: Co-injection of rFVIII with IVIG decreased the anti-FVIII immune response in previously untreated hemophilia A mice. These findings suggest that IVIG co-administration can be effective in management of hemophilia A patients at risk of inhibitor development.

subject:
Tibia Fracture

Clinical Epidemiology

abstract:
The following graduate thesis aims to identify important clinical variables, including injury, treatment and healing characteristics, that serve as prognostic indicators for complications in patients with fractures of the tibial shaft. In particular, the complications of focus in this thesis are surgical site infections and nonunion. The three analytical studies comprising this thesis were derived from large data sets arising from two randomized controlled trials and an observational cohort study.
The first chapter (Open Tibial Fractures: Updated Guidelines for Management) is a published literature review that provides an overall introduction to the thesis. It highlights the paucity of high-quality evidence currently available to inform many of the treatment strategies for patients with open fractures of the tibial shaft.
The second chapter (Timing of Irrigation & Debridement and Infection Risk in Severe Open Fractures) is a sub-study of all open fracture patients recruited in the International Orthopaedic Multicenter Study (INORMUS) in Fracture Care. The findings of this study suggest that timing delays to irrigation and debridement for patients with open fracture injuries is associated with an increased risk of surgical site infection.
The third and fourth chapters evaluate the association between early healing measures and nonunion in patients with tibial fractures. Specifically, chapter three (Exploring the Association of 3-Month Radiographic Union Score for Tibia Fractures (RUST) with Nonunion in Tibial Shaft Fracture Patients) demonstrates that radiographic healing at three months post-operatively is strongly associated with nonunion at one year. Similarly, chapter four (Nonunion in Patients with Tibial Shaft Fractures—Can Early Functional Status Predict Healing?) demonstrates that functional status at three months post-operatively is also correlated to eventual healing. Both of these studies include patients from the randomized controlled trials, SPRINT (Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures) and FLOW (Fluid Lavage of Open Wounds).

abstract: Thesis

abstract: Master of Science (MSc)

abstract: The enclosed thesis work evaluates outcomes in patients with fractures primarily of the tibial shaft. In particular, the comprised studies assess whether certain characteristics, such as injury factors, treatment variables and early healing progression, are associated with adverse outcomes in these patients. One study found that delays in timing to appropriate surgical care for patients with open fractures (open wound at the site of the fracture) leads to greater risk of infection. Furthermore, two studies found that both the level of radiographic healing and functional status of patients at three months from surgery can help predict if the patient will ultimately heal radiographically at one year from injury. The findings of this thesis work should help orthopaedic care providers identify patients at high risk for infections and nonunions, such that these patients can be closely monitored to minimize the risk of such complications.


title: Angels Associated with Israel in the Dead Sea Scrolls

title: A Study of Angelology and Community Identity at Qumran

contributor:
Schuller, Eileen

subject:
Dead Sea Scrolls
Angels
Community Identity
Angelic Fellowship

abstract:
A well-known characteristic of the Qumran sectarian texts is the boast that community membership included fellowship with the angels, but scholars disagree as to the precise meaning of these claims.  In order to gain a better understanding of angelic fellowship at Qumran, this study utilizes the fact that an important facet of Early Jewish angelology was the concept that certain angels were closely associated with Israel.  Specifically, these angels can be placed in one of two categories: guardians (i.e., warriors who strove against Israel’s enemies, celestial or otherwise) and priests (i.e., the celebrants of the heavenly temple).  A crucial component of the presentation of both angelic guardians and angelic priests was that they were envisioned within apocalyptic worldviews that assumed that realities on earth mirrored those of heaven, with the latter serving as the ideal, archetypal, or “more real” world.  After discussing the conceptual backgrounds of angels associated with Israel in the Ancient Near Eastern texts and in the pre-exilic, exilic, and early post-exilic texts of the Hebrew Bible, this study sets out to compare how angelic guardians and angelic priests are presented in both the sectarian texts and the late Second Temple Period compositions of a non-sectarian provenance found among the Dead Sea Scrolls.
While the non-sectarian compositions clearly posit a connection, correspondence, or parallel relationship between the angels and the Jewish people, an interesting facet of these works is that they imply definitions of Israel that are either quite generous or more stringent but paradoxically tempered by universalistic sentiments.  Conversely, the witness of the sectarian compositions is that the Yahad viewed itself alone as the true Israel of God, with these texts evincing the belief that the angels associated with Israel had a unique connection to the sectarians, who had effectively usurped for themselves the privileges that were formerly those of the entire nation.  Moreover, the texts which speak of angelic fellowship – both during the eschatological war and in the present time – suggest that sect members upheld the lofty self-estimation that they were either equal to the angels in some sense or had even attained a rank and glory higher than the angels.  Given that the sectarians were convinced that their reconstitution of Israel’s covenant was the nation as it ought to be, there arguably would have been no better way for the Yahad to promote itself as such than to boast that the sect members were equal to – and even outranked – the guardians and priests of heavenly, archetypal Israel.  Thus, while there has been scholarly disagreement as to the exact meaning of the sectarian angelic fellowship claims, this thesis demonstrates that at least part of the meaning is to be found in the contribution these claims make to the identity of the sect as the true Israel of God.

abstract:
Connected and automated vehicles (CVs and AVs, respectively) are rapidly emerging paradigms aiming to deploy and develop transportation systems that enable automated driving and data exchange among vehicles, infrastructure, and mobile devices to improve mobility, enhance safety, and reduce the adverse environmental impacts of transportation systems. Based on these premises, the focus of this research is to quantify the potential benefits of CVs and AVs to provide insight into how these technologies will impact road users and network performance.
To assess the traffic operational performance of CVs, a connectivity-based modeling framework was developed based on traffic microsimulation for a real network in the city of Toronto. Then the effects of real-time routing guidance and advisory warning messages were studied for CVs. In addition, the impact of rerouting of non-connected vehicles (non-CVs) in response to various sources of information, such as mobile apps, GPS or VMS, was considered and evaluated. The results demonstrate the potential of such systems to improve mobility, enhance safety, and reduce greenhouse gas emissions (GHGs) at the network-wide level presented for different CVs market penetration.
Additionally, the practical application of CVs in travel time estimation and its relationship with the number and location of roadside equipment (RSE) along freeways was investigated. A methodology was developed for determining the optimal number and location of roadside equipment (RSE) for reducing travel time estimation error in a connected vehicle environment. A simulation testbed that includes CVs was developed and implemented in the microsimulation model for Toronto 400-series highway network. The results reveal that the suggested methodology is capable of optimizing the number and location of RSEs in a connected vehicle environment. The optimization results indicate that the accuracy of travel time estimates is primarily dependent on the location of RSEs and less dependent on the total density of RSEs.
In addition to CVs, the potential capacity increase of highways as a function of AVs market penetration was also studied and estimated.  AVs are classified into Cooperative and Autonomous AVs. While Autonomous AVs rely only to their detection technology to sense their surroundings, Cooperative AVs, can also benefit from direct communication between vehicles and infrastructure. Cooperative car-following and lane-changing models were developed in a microsimulation model to enable AVs to maintain safe following and merging gaps. This study shows that cooperative AVs can adopt shorter gap than autonomous AVs and consequently, can significantly improve the lane capacity of highways. The achievable capacity increase for autonomous AVs appears highly insensitive to the market penetration, namely, the capacity remains within a narrow range of 2,046 to 2,238 vph irrespective of market penetration. The results of this research provide practitioners and decision-makers with knowledge regarding the potential capacity benefits of AVs with respect to market penetration and fleet conversion.

 Stable thin-film resistors were fabricated using nichrome as the
resistance material. The variation of resistance value with both temperature and time was investigated.

 A metal-cadmium sulphide-metal structure was employed as a thin-film diode, the electrodes being of aluminium or gold. The electrical evaluation of such a device demonstrated the importance of the deposition of the semiconductor on the rectifying properties. Forward to reverse resistance ratios of 10^5 were observed for experimental units.

 The staggered-electrode structure was incorporated in the production of thin-film transistors. Cadmium sulphide was used as the semiconducting material while silicon monoxide and aluminium were used as the insulator and electrodes respectively. Operating devices exhibiting good saturation characteristics has transconductances of 450μ mhos. Simple circuits were constructed to demonstrate the performance
of thin-film transistors.

title: The De Haas-Van Alphen Effect in Mercury

Datars, W. R.
Physics

subject: De Hass-Van Alphen, Mercury, magnetic fields, Fermi Surface, phonons, crystals

abstract:
 Field modulation techniques were used to observe the de Haas-van Alphen effect in magnetic fields up to 5.5 tesla and at temperatures below 1.1°K. A data acquisition system
recorded on magnetic tape the large amount of data necessary for computer fourier analysis of the oscillations. All of the orbits predicted by Keeton and Loucks' model of the Fermi surface of mercury were at least tentatively identified. The data on the β, τ and α orbits were in essential agreement with previous work. The γ and X-face orbits were also investigated in some detail, while tentative identification was made of the μ and T-face orbits. When the data permitted, the areas were fitted to ellipsoids or hyperboloids of revolution by a least squares calculation.

 A search was made for modifications to the de Haas-van Alphen theory due to phonons. Accurate torque de Haas-van Alphen amplitude measurements were taken as a function of temperature and magnetic field. The analysis of the results revealed no systematic dependence of either the cyclotron effective mass or the Dingle temperature on temperature from 1.25°K to 4.2°K or on magnetic field from 1.5 tesla to 2.3 tesla. Thus no effects due to phonons were observed.

 A method of observing the open orbits in metallic single crystals was developed and used to observe the open orbits in mercury. The method utilized the eddy currents induced in the sample by the rotation of a magnetic field. This provided a signal which was dependent on the conductivity in the plane perpendicular to the open orbit. The torque amplitude, which indicated the number of open orbit carriers, was used to detect the angular range of the bands of open orbits in mercury. The method was experimentally simple since no special sample geometry was necessary and no electrical connections to the sample were needed.

title: Studies of the Endothelial Protein C Receptor

subject:

hematopoiesis

abstract: The endothelial protein C receptor (EPCR) binds to protein C (PC) and increases the rate of activated protein C (APC) generation by the thrombin-thrombomodulin (TM) complex. APC exerts anticoagulant, anti-inflammatory, and cytoprotective effects, which are EPCR-dependent. The thrombin-TM complex is also a potent activator of thrombin activable fibrinolysis inhibitor (TAFI), leading to impaired clot lysis.  Mutations and polymorphisms identified in the EPCR gene, which can affect the efficiency of PC activation, have been associated with an increased risk of thrombosis. In this thesis we investigate the impact of impaired PC binding to EPCR on coagulation, inflammation, and fibrinolysis using novel in vitro and in vivo models.  Using a murine model that harbours a variant of EPCR that does not bind PC (R84A), we demonstrate that upon thrombotic challenge, there is an increase in thrombin generation and fibrin deposition in the lungs. Upon inflammatory challenge, impaired PC/EPCR interactions also result in increased thrombin generation and increased neutrophil infiltration into the lungs. Using cells that express TM and a human variant of EPCR that does not bind PC (R96C), we demonstrate that clot lysis is delayed in normal plasma independent of TAFI activation, suggesting PC and TAFI do not compete for activation by the thrombin-TM complex. In contrast, delayed clot lysis in plasma deficient of PC is a result of greater TAFI activation by the thrombin-TM complex. Taken together, impairment of the PC pathway contributes to thrombosis through pro-coagulant, pro-inflammatory and anti-fibrinolytic mechanisms. Interestingly, mice with EPCR variant R84A, develop bone marrow failure and splenomegaly, revealing a novel role for EPCR in the bone marrow. Taken together, PC/EPCR interactions regulate the coagulation, inflammation, and fibrinolytic pathways, which may have a significant impact on maintaining hematopoietic homeostasis.

abstract: Under normal conditions, blood is maintained in a fluid state.  Upon injury or infection, the blood begins to form a clot to prevent bleeding. Once bleeding has stopped the clot is dissolved and blood regains its fluid state.	The formation of a blood clot is a serious and potentially life threatening disease. A blood clot formed inside a blood vessel can block the flow of blood through the circulation, leading to organ damage.  Approximately 50% of blood clots are caused by known genetic or environmental factors, leaving 50% of blood clots caused by unknown factors. In this thesis we investigate the unknown factors that contribute to blood clotting.  In patients who have experienced blood clots with no known cause, we have identified genetic mutations in a blood vessel wall protein, known as the endothelial protein C receptor (EPCR) that renders it non-functional. We demonstrate both in vitro and in vivo that non-functional EPCR not only leads to the formation of a blood clot but also delays the removal of the blood clot.  Our in vivo studies have also revealed a previously unknown role for EPCR in the bone marrow, likely through its effects on blood coagulation. Taken together, loss of EPCR function contributes to the development of clot formation and likely impacts other organ systems.

abstract: Title: Travel and Tourism in Ecuador, Author: Claire M. Moran, Location: Thode

abstract:
Travel, for leisure or business purposes, can contribute to a country's development process in three ways. It creates a demand for goods and services. National travellers generally consume goods and services produced domestically. International travellers generate
foreign exchange. Ecuador has many more national travellers than international travellers. Given its oil exports, Ecuador also faces less of a foreign exchange constraint than many developing countries. Hence, Ecuadorean planners can, and should, pay more attention to the
role of national travel and tourism in the development process of their country.

A review of the literature on travel in developing countries reveals that the emphasis is frequently on international travel. In this study, national and international travel are analysed and compared with regard to their role in the development process. This study examines specific spatial, seasonal, and sectoral features of travel and tourism in eight surveyed centers in Ecuador. Five hypotheses about these features of travel and tourism were tested with data
collected by means of questionnaires and interviews.

The analysis suggests that the spatial, seasonal, and sectoral effects of national travel and tourism can assist the development process in Ecuador better than those of international travel and tourism. Therefore, development planning in Ecuador, unlike that in many other developing countries, need not stress the role of international travel. The study concludes with suggestions for some broad policy guidelines, for consideration by Ecuadorean planners, emphasizing national travel in the development process.

abstract:
 High index contrast optical waveguides have recently attracted much attention as a promising platform for ultradense photonic integrated circuits. The vector nature and fine geometry of such waveguiding structures impose new challenges for numerical modeling. By introducing the high-order finite-difference method, highly accurate and efficient modeling techniques have been developed in this thesis for simulation and design of high index contrast waveguiding structures with compact size.

 High-order mode solving techniques are first presented for modal analyses. Their advantages in accuracy have been demonstrated for high index contrast optical waveguides and bent waveguides with small bending radius.

 Later, a class of high-order propagation algorithms, including the paraxial and
wide-angle beam propagation methods, reflective operator method and bidirectional beam
propagation method, have been developed for modeling longitudinally slow-varying structures, single waveguide discontinuity and piecewise z-invariant structures, respectively. All the proposed propagation algorithms have been shown to provide significant improvement in accuracy and efficiency in comparison with conventional methods, especially when simulating high index contrast structures with small feature size.

 Accurate modeling of evanescent waves is critical for the simulation of strongly reflecting structures with high longitudinal index contrast. Various rational approximations to square root operators used in the bidirectional beam propagation method have been comprehensively assessed. Useful guidelines for accurate modeling of evanescent and propagating modes are provided.

 Finally, the efficient high-order bidirectional beam propagation method is introduced for the design of Bragg gratings on high index contrast and plasmonic waveguides. Good performance is achieved.

abstract:
A flexible, modular program system for the synthesis of optimal
energy exchange networks (OPENS) is developed. It is capable of generating
realistic process equipment networks to satisfy both stream temperature and
pressure specifications. The system contains elements of heuristic decision
making and employs a "branch and bound" combinatorial technique for solving the
discrete problem of optimizing network configuration. An (energy) price-based
decomposition algorithm is developed for sub-process integration; this is
achieved by determination of the optimal (stream) interconnections between such
sub-processes .

The system is applied to the design of energy recovery networks for
two quite dissimilar ethylene recovery schemes; the high and low pressure
processes. Process interactions between the main processing sequence and the
associated refrigeration facility are used to explore sub-process integration.

Some conclusions are made regarding the effectiveness of the program
system for the example processes presented and recommendations are made for
improvement and extensions .

abstract:
Objectives: The purpose of this thesis is to explore the associations between childhood cognitive abilities assessed at age 8 and health and socioeconomic outcomes at age 29-36 in extremely low birth weight survivors (ELBW, <1000g).
Methods: Using data from the McMaster Extremely Low Birth Weight Cohort Study, Study 1 explores the influence of overall intelligence, fluid intelligence, and language abilities on the prevalence of lifetime major depressive disorder in ELBW survivors and normal birth weight comparison subjects. Study 2 examines the mediating role of overall intelligence, fluid intelligence, language abilities, quantitative reasoning, and academic achievement on the association between being born at ELBW and socioeconomic outcomes at age 29-36. The final study examines the moderating role of childhood cognitive functioning on links between postnatal psychosocial adversity and adult personal earnings in ELBW survivors.
Results: Results from Study 1 suggest that childhood cognitive abilities do not influence the onset of major depressive disorder in ELBW survivors, but are protective against depression in normal birth weight individuals. Study 2 suggests that childhood cognitive abilities partially mediate the association between being born at ELBW and income attainment in adulthood, but not full time employment. Further, Study 2 suggests that this association is stronger in ELBW survivors who have neurosensory impairments. Results of Study 3 suggest that enhanced childhood cognitive functioning is not protective against postnatal psychological adversity in influencing income attainment, as those ELBW survivors with higher childhood intelligence and who suffered psychological adversity reported lower annual income at age 30.
Conclusions: This thesis suggests that overall and specific cognitive abilities significantly influence adult outcomes in ELBW survivors and normal birth weight individuals. However, while cognitive reserve may not be protective against psychological adversity in ELBW survivors, early cognitive abilities are a critical indicator of socioeconomic attainment in this vulnerable population.

abstract:
This thesis is a study of massive star formation: the environments in which they form and the effect that their radiation feedback has on their environments. We present high-performance supercomputer simulations of massive
star formation inside molecular cloud clumps and cores. First, we present a novel radiative transfer code that hybridizes two previous approaches to radiative transfer (raytracing and flux-limited diffusion) and implements it in
a Cartesian grid-based code with adaptive mesh refinement, representing the first of such implementations. This hybrid radiative transfer code allows for more accurate calculations of the radiation pressure and irradiated gas temperature that are the hallmark of massive star formation and which threaten to limit the mass which stars can ultimately obtain. Next, we apply this hybrid radiative transfer code in simulations of massive protostellar cores. We
simulate their gravitational collapse and the formation of a massive protostar surrounded by a Keplerian accretion disk. These disks become gravitationally unstable, increasing the accretion rate onto the star, but do not fragment to
form additional stars. We demonstrate that massive stars accrete material predominantly through their circumstellar disks, and via radiation pressure drive large outflow bubbles that appear stable to classic fluid instabilities. Finally,
we present simulations of the larger context of star formation: turbulent, magnetised, filamentary cloud clumps. We study the magnetic field geometry and accretion flows. We find that in clouds where the turbulent and magnetic energies are approximately equal, the gravitational energy must dominate the kinetic energy for there to be a coherent magnetic field structure. Star cluster formation takes place inside the primary filament and the photoionisation feedback from a single massive star drives the creation of a bubble of hot, ionised gas that ultimately engulfs the star cluster and destroys the filament.

abstract: Title: Dundas an Urban Study, Author: Irene Meyers, Location: Thode

abstract:
The Town of Dundas located at the extreme west end of Lake Ontario in the township of West Flamborough in the County of Wentworth, (Figure l) is an interesting study both in regard to its historical aspect and to its present day situation. It is my purpose to explain in the following chapters, why Dundas with its numerous natural advantages has not become a larger centre than it is today. Naturally the physical location of any urban centre is of great importance. This is especially true in the case of Dundas where the presence of the gap formed by the Dundas Valley is of great economic and commercial significance. Importance attaches to this valley because it determines the location of the chief road and rail routes from Lake Ontario to south-western Ontario, including the Guelph line of the C.N.R. which climbs its walls. the Physiographic basis of the town itself is important as it is restricted in the north and south by escarpment, in the east by the marsh, and in the west by the uneven nature of moraine.
I have emphasized the historical background of Dundas as it offers the key to Dundas of today and explains many of the fathers not at first evident. As it was transportation that gave Dundas its early pre-eminence and which later relegates it to a minor position in relation to Hamilton, I have based the historical divisions primarily on the predominance of the various types of transportation facilities: the route into the interior superimposed upon the old Indian trails, the coming of more adequate road systems, the era of canal prosperity, and finally the advent of the railways. Each had a definite and distinct effect on Dundas, its functions and its physic appearance.

abstract:
Th purpose of this study is to present a description
of the natural and cultural landscapes of Whitby Township,
and an analytical examination of the relationships which
exist between them.

The study has been divided into three chapters,
chapter one dealing with the physical geography under
several headings, chapter two being a brief historical
account of the Townships settlement and the evolution of
agriculture. Chapter three seeks to relate the present land
use of both Whitby Town and Township, with the physical and
cultural features which have been important in development
up to the present. In order to do this, the concept of a
"development area" was adopted. Each development area, of
which there are three, has its own particular character,
which has developed due to the predominance of one or more
of the physical or cultural features . The development
areas should not, however, be thought of as being distinctly
separated one from another. Rather, their division is by
a transitional zone, which is difficult to map and has been
represented in Figure 4 by a line which passes through the
general area where a change in landscape is noted. Neither
should these areas be thought of, in the final analysis, as
being separate units within the Township. The summary of
the study illustrates this as it attempts to depict the
Township as a whole and discusses the areas as a group on the basis of present conditions and future prospects .

The field work for this study was carried out during
the last two weeks of August and the first two weeks of
September 1958. The land use map represents conditions
during this period, Mapping was done through field
observations with the use of aerial photographs the
Ontario Country Soil Survey and The Physiography of
Southern Ontario by L.J. Chapman and D.F. Putnam. These aids
along with other articles and book listed in the bibliography
were of great help in writing the text of this study. Besides
mapping, the field research included interviews with Town and
Township officials, agriculturalists, and persons concerned
with urban activity.

Most of the statistical information in the text was
obtained from the Dominion Census Reports, either directly
or by way of municipal brochures. Where the actual acreage
of an area is given. The acreage has been derived from
planimetric measurement, and where a proportion of
acreages is given, it is the writer's opinion based on

subject:
Sarcasm
Paul
2 Corinthians
Irony

abstract: This thesis takes as its subject Paul’s use of sarcasm, using 2 Corinthians 10–13 as a case study. While there has been some work done on the related subject of irony in the Pauline corpus, scholarship has not addressed the issue of sarcasm specifically. For this reason, not only is a dedicated work on sarcasm useful for its own sake, but it also has the potential to nuance previous work on irony, as it can be difficult to generalize when dealing with such a broad rhetorical category. Due to the paucity of previous work on sarcasm – or related subjects – in Paul, the second major contribution of the study will be methodological. The goal of this discussion is to generate a working definition of sarcasm and to develop techniques for sarcasm recognition in ancient texts. To this end, I will survey ancient and modern thought on sarcasm so as to benefit from the insights of contemporary research while grounding the work in categories relevant to a Pauline context. Following the question of method, the final task will be an analysis of 2 Cor 10–13. Here the aim is threefold: to identify and analyze sarcastic statements, to address instances where the presence of sarcasm can contribute to the discussion of exegetical issues, and finally, to draw broader conclusions about the rhetorical effects of Paul’s use of sarcasm.

abstract: Master of Arts (MA)

abstract: This thesis analyzes Paul’s use of sarcasm in 2 Corinthians 10–13. To this end, the first two chapters seek to answer the questions: What is sarcasm? And, how do we find sarcasm in ancient texts far removed from our own culture? We approach these questions by surveying both ancient and modern thought on sarcasm. The goal at this point is to draw as straight a line as possible from classical to contemporary discussions, so that our analysis of Paul can benefit the insights of recent work while remaining grounded in terms current to Paul’s day. With this background, it is then possible to address Paul’s use of sarcasm in 2 Corinthians 10–13. The primary aims of this chapter are to identify sarcastic statements and analyze how they contribute to Paul’s overall argumentation. Additionally, instances where our analysis can contribute to scholarly debates over certain passages are also addressed.

abstract:
The Crystal field is found in townships 45 and 46 in the
ranges 3 and 4WS. The field differs from other Viking fields
by being smaller, thicker, elongate in a north-south
direction, and is conglomeratic.

Cross-sections of the well logs and lithologs show four
extensively bioturbated, sandier-upward cycles that occur on
a regional scale in the study area. The cyclic nature of
these sediments may be due to distant, unknown aggrading
shorefaces, possibly associated with minor relative sea
level fluctuations. At Crystal, the cycles are cut out at
various levels by an asymmetrical erosion surface. In the
west-central area of the field there are two possible
surfaces that may be equivalent to the main erosion surface.
All of the erosion surfaces have been interpreted as being
bases of incised shorefaces. The shoreface movement may be
due to fluctuations in the relative sea level.

In the western side of the field, lithologs show the sand
above these erosion surfaces as being predominantly
laminated with a low-angle of inclination and/or laminated
that grades into bioturbated tops. Toward the eastern side
of the field, the sand gradually becomes more cross-bedded
and pebble-rich. The sediment above the erosion surfaces is
interpreted as preserved upper to mid shoreface deposits.

The top of the Viking at Crystal may be another erosion
surface due to a major transgression.

abstract: Title: Start-Up of the PHW 600 Reactor with a Reduced Initial Core Loading, Author: Charles Olive, Location: Thode

abstract:
Savings, in terms of increased first charge burnup
and lower fuel inventory costs, are made when a CANDU
reactor is started up with a reduced initial core loading.
Enough fuel is loaded to make the reactor critical and then
progressively added to the outer channels to maintain criticality
during operation over the initial transient. As more
fuel is loaded, the form factor improves permitting the reactor
power to be increased. When the last channel is loaded,
full power can be achieved.

The trade off between decreased fuel costs and energy loss
has been investigated by simulating operation to 300 full power
days (FPD) with a two dimensional fuel management program for
various initial loadings of the PHW 600 reactor. The results
for the reference case (fully loaded initial core producing
full power from start-up) were available from a previous study
(2). It was found that the optimum trade off occurred for an
initial loading of about 95%. A 3% improvement in first charge
burnup was obtained which was offset by an energy loss of 8 FPD
over the initial transient. The maximum burnup improvement, for
34% initial loading, was about 13% with an energy loss of 73 FPD.

It was concluded that the reduced core concept can be used
to advantage only by a utility which does not require full power
immediately. If, however, the lost energy has to be replaced
from another source, utility operating costs are minimized by
starting up under normal conditions owing to relatively high
replacement energy costs.

abstract:
The catalytic hydrogenolysis of propane and n-butane have been investigated in an integral packed bed reactor (0. 70 cm. I.D. by 25. cm. long). The catalyst was 10.% nickel on silica gel. A blocked factorial set of experiments were performed at hydrogen to butane feed ratios of 4. to 9., temperatures of 240. °C. to 282. °C. and feed flowrates of 1.0 to 1. 8 ml./sec. Kinetic rate expressions were developed to predict the
product distribution, taking into account increasing catalytic activity. A proposed parameter estimation strategy, applying non-linear regression theory, was used to obtain the ten kinetic parameters. Error analysis of the parameters using likelihood ratios is included. Models were developed to describe the catalyst activity changes observed during experimentation. The kinetic models predict the experimental observations very accurately over all conversions and show considerable deviation
only at the combination of high temperature and low feed ratio.

The butane kinetic model was incorporated into proposed fluidized bed reactor models and sensitivity analyses were performed on catalyst activity and the interchange parameter.

abstract: Molecular breast imaging (MBI) is a relatively new clinical breast imaging modality, which has the potential to have a significant impact in breast cancer screening and perioperative breast imaging for women with high risk factors for developing breast cancer. Two objectives were proposed in this thesis to increase the use of MBI. First, a magnetic resonance (MR)-compatible gamma camera was developed for combined molecular/MR breast imaging. MBI is a functional imaging technique with high specificity and sensitivity but could benefit from the addition of anatomical information from breast MRI for lesion localization, cancer staging, treatment planning and monitoring. A small area (8cm x 8cm) cadmium zinc telluride (CZT) based gamma camera was developed and tested for MR compatibility in both sequential and simultaneous imaging conditions. Results indicated that the gamma camera was minimally affected during both sequential and simultaneous imaging with a gradient echo (GRE) and spoiled gradient echo (GRE) sequence. Signal to noise ratio (SNR) degradation was observed in the MR images but no geometric distortions were observed. Simultaneous imaging is feasible, but a reassessment of the RF shielding would be required to minimize the noise contribution degrading image quality. Second, backscatter photons were investigated as a potential dose reduction technique for MBI. While the effective dose from MBI is relatively low in comparison to other nuclear medicine procedures, the dose is considered high in relation to mammography and in order to increase acceptance as an alternative breast imaging method, dose reduction is an important objective. Backscatter photons have the same spatial information as primary photons but are typically discarded along with other scattered photons. A scatter compensation method called the triple energy window (TEW) was used to extract backscatter photons from the Compton scattering spectrum and added to the primary photons, increasing count sensitivity by 6%. The noise level matched the increase in contrast leading to negligible change in lesion contrast to noise ratio (CNR). Dose reduction is not justified with this particular technique because of the elevated noise level, but the use of backcsatter photons show potential with improved contrast.

abstract:
The nuclear energy level structure of the three odd-Z nuclei 173Lu, 175Lu and 177Lu have been investigated using the (3He,d) and (α,t) reactions. The resulting spectra have been interpreted using the Nilsson model with corrections for Coriolis coupling and pairing effects. The present work confirms the earlier assignments of the 7/2+[404] and 5/2+[402] proton orbitals in all three nuclei. New assignments are
made for the 9/2-[514] orbital in 173Lu and the 1/2-[541] orbital in 177Lu. The assignment of these states is confirmed in the remaining nuclei in each case. The assignment of the 1/2+[411] orbital is confirmed in 173Lu and 177Lu but the
state as not been assigned in 175Lu. In addition, assignments are proposed for the 1/2-[530] and 3/2-[532] proton orbitals above 1 MeV excitation in all three nuclei.

The structure of the odd-odd nucleus 174Lu has also been studied using the (3He,d), (α,t), (3He,α) and (d,t) reactions. The proton transfer data have enabled the assignment of the 1/2-[541], 5/2+[402], 9/2-[514] and the 1/2-[530] proton
orbitals coupled to the 5/2 [512] neutron in both spin triplet and singlet configurations. Strong Coriolis coupling has been observed in bands formed by the transfer of the 1/2-[541] and the 1/2-[530] protons. The neutron transfer data have been used to confirm previous assignments of the 5/2-[512], 1/2-[521] and
3/2-[521] neutron orbitals coupled to the 7/2+[404] proton. The observation of levels populated by high-ℓ transfers in the (3He,α) reaction has led to a revised assignment of the Kπ = 7+ , {7/2+[633] + 7/2+[404] } rotational band. Similarly the spin
triplet Kπ = 0+ configuration of these two orbitals has also been identified.

abstract: Title: Ion Impact Phenomena in Anodic Oxides, Author: Lam Q. Nghi, Location: Thode

abstract:
In this thesis results are presented relating to sputtering coefficients
of Kr on anodic oxides, high-dose depth distributions of Kr in Al2O3, Nb2O5, and WO3, and amorphization in crystalline WO3.

The comparison of the experimental sputtering data with Sigmund's theory permits the surface binding energy to be estimated. Possible contribution
of volatility to sputtering will be discussed for the case of volatile oxides with stable gaseous multimers, namely MoO3, V2O5, and WO3.

The pronounced "range shortening" has been studied in detail
for high doses of Kr in Al2O3, Nb2O5, and WO3, and is shown analytically
to be reasonable whenever there exists an appropriate spatial variation
in the diffusion activation enthalpy. Effects of pre-bombardment and
post-bombardment on depth distributions, as well as information on the
migration of implanted dopants near room temperature, are argued as providing a self-consistent explanation for the above-mentioned "range shortening".

Depths of amorphization due to ion impact have been measured with WO3. They are then used to deduce the critical fraction of atomic displacements leading to amorphization, the mean size of discrete disordered regions, and estimates of the damage mean range for Kr-WO3.

abstract: Title: Uranium-Series Dating of Speleothems as a Means of Determining Glabal Paleoclimates, Author: Jane Mulkewich, Location: Thode

abstract:
770 speleothem dates were collected, and the probability of speleothem growth over time was calculated by fitting a normal distribution to each date, using the one sigma standard deviation. The distribution of recovered speleothem samples approximates an exponential curve, but it is not a simple function. By distinguishing between base
dates and top dates and comparing them, glacial periods can be distinctly identified. Thirteen glacial and interglacial stages were recognized in the last 350,000 years. Despite the difference in number from the nine stages of the deep-sea oxygen isotope record, the curves are similar, and the two chronologies are mutually reaffirming.

title: Some Theoretical Aspects of the Impact of Selected Demand and Technological Conditions on the Optimum Location of the Firm

Betak, J. F.
Geography

subject: theoretical, selected demand, technological, optimum, location, firm, non-linear

abstract:
 The Objective of this study is to investigate analytically the impact of certain technological and market conditions on the optimum location of the firm. The existing location models may be divided into those which consider both supply and demand aspects and those which concentrate on supply factors alone. Traditionally, the former group of models define equilibrium as the profit maximizing location and assume both a linear-homogeneous production function and a linear demand function. The latter class of models assume only the linear-homogeneity of production, and equilibrium is found at the cost-minimizing site.

 In this paper two cases are examined. Firstly, the influence of a general non-linear homogeneous production function on a simple cost minimizing model is considered. Secondly, the effect of non-linear demand functions and non-linear homogeneous technology on a profit maximizing model are assessed. The results indicate that the optimum location in the cost minimizing situation does not vary with the level of output, whatever the degree of homogeneity of the production function. This directly contradicts the common belief regarding the effects of production. Furthermore, in the profit-maximizing problem, and with non-linear homogeneous production, the solution is unaffected by the shape of the demand function.

 Suggestions for refining and extending this analysis include the use of general rather than specific demand, transportation and production functions: the employment of exhaustible inputs, and generalization to the three-dimensional situation.

abstract:
 This thesis presents a study on silane based polymerization in two parts.

 In Part A, diphenylvinylsilane (1) underwent oligomerization with initiation by azo(bisisobutyronitrile) (AIBN) or benzoyl peroxide (BPO). The vinyl groups were preferentially consumed under either set of conditions. Several products were isolated; these included oligomers 3, an AIBN adduct 4, a dimer 5, and a trimer 6. The residual SiH moieties could be subsequently coupled hydrosilylatively with alkynes or vinylsilicones. The efficiency of the radical reactions was very low. 15% starting material was recovered even with 200 mol% of initiating radicals added to the reaction mixture. The relative radical reactivities of the two functional groups is discussed.

 In Part B, 1 was radically copolymerized with styrene and methyl methacrylate (MMA). From the results of infrared and 1H NMR it was determined that 1 participated in copolymerization via a vinyl type polymerization and not in the form of a hydrogen-transfer type polymerization. Residual SiH groups along the backbone of the polymer remained reactive. A vinylsilicone and 9-vinylanthracene were grafted onto the copolymer from MMA and 1 by hydrosilylation and radical methods, respectively.

abstract:
 The atomic beam magnetic resonance technique with radioactive detection has been used to investigate the hyperfine structure of In^117m. The present research is based on the work done by Cameron (1962) who could not obtain accurate values for the hyperfine interaction constants due to the low neutron flux at the time in the McMaster reactor.

 This thesis is an account of an attempt to complete that experiment by observing the field independent direct hyperfine transitions. The theory of the experiment, the apparatus and techniques, and the method of data analysis are described. Because of the counting errors, the data are not as conclusive as had been hoped. If the resonances have, in fact, been seen, then the results are: a1/2 = -932.996 ± 0.012 Mc/sec
a3/2 = -99.005 ± 0.005 Mc/sec
μI = -0.25146 ± 0.00003 nuclear magnetons.

abstract: The goal of this paper is to extend Sanders Mac Lane's formulation of the torsion product as equivalence classes of projective chain complexes in the setting of modules over a ring to the setting of modules over small categories. The motivation to extend the definition was with a specific view to the orbit category. The main difficulty was in defining an appropriate dual for modules over small categories. During the course of our investigation it was discovered that modules over small categories can be formulated as modules over a matrix ring without losing any of the key features.

abstract:
 Reaction of the hydrated trichlorides of rhodium and Iridium with hexamethyldewarbenzene gave the complexes, (C5Me5MCl2)2 (M=Rh, Ir). A mechanism for this reaction is proposed.

 The dichloro complexes, (C5Me5MCl2)2, were reacted with a number of di- and tri-enes in ethanol in the presence of base and gave a variety of pentamethylcyclopentadienyl complexes of M(l) and M(lll). Evidence for a hydrido intermediate is presented and the hydrido- and deuterido- complexes, C5Me5IrH(D)ClPPh3, were isolated
and characterised.

 The isomers endo-H and exo-H pentamethylcyclopentadiene(cyclopentadienyl) rhodium were isolated and showed significant differences in their properties. Cyclooctadienes reacted with (C5Me5MCl2)2 to give C5Me5M(1,5-C8H12) via the intermediacy of the π-2-cyclooctenyl complexes C5Me5MCl(C8H13); mechanisms are presented to account for the observed products. Cyclohexadienes gave the complexes, C5Me5M(1,3-C6H8). 1,4-Cyclohexadiene was isomerised to 1,3-C6H8; the rhodium complex, C5Me5Rh(1,3-C6H8), was a very active catalyst for the disproportionation of 1,3-C6H8 to cyclohexene and benzene, both ethanol and base were cocatalysts.

 Mass spectral data for these and other organo-metallic complexes are presented.

abstract: Title: The Sedimentology, Stratigraphy and Depositional History of the Lower Cretaceous Viking Formation at Caroline and Garrington, Alberta, Canada, Author: Stephen D. Davies, Location: Thode

abstract:
The Lower Cretaceous (Albian) Viking Formation at
Caroline and Garrington, Alberta contains two regionally
extensive erosion surfaces, VE3 and VE4, separating three
allocyclic members, B/C, D, and E. These erosion surfaces,
along with two possible correlative conformities at lower
stratigraphic levels, can be mapped over large areas of the
Alberta Basin allowing for the creation of a Viking
Allostratigraphy.

The basal allomember cored in the study area is
informally termed B/C and is made up of burrowed siltstones
deposited in an offshore marine setting. It is overlain by the
regionally extensive ravinement surface VE3, which rises
"steplike" towards the southwest. Allomember D, which overlies
this unconformity, is composed of a shallowing upward
succession of storm-dominated facies resulting from
progradation of the shoreface towards the northeast.
Allomember E is a complex succession of facies deposited over
the regionally extensive ravinement surface VE4 during the
final relative rise of the Boreal sea. Within Allomember E are
up to six coarse grained, sheetlike beds sharply interbedded
with marine shales. These interbeds are the result of
basinward progradation of coarse sediment during periods of
stillstand in the overall transgression, under the mixed
influence of storms and tides. The coarse grained deposits originated at "steps" in the VE4 topography, representing
successive positions of the retreating paleoshoreline, · and
were swept basinward by. tides and storms over older,
stratigraphically deeper "steps" and newly deposited shales.
The coarse grained interbeds in Allomember E become thinner
and finer in any one vertical section, reflecting the
continued transgression of the shoreline towards the
southwest.

The boundaries of the Caroline and Garrington fields are
determined by the extent of the sheetlike coarse grained
deposits of Allomember E, and by the location of the postdepositionally
determined oil-water contacts. Caroline and
Garrington are producing from different stratigraphic
intervals. caroline is producing from a shale-encased coarse
grained interbed termed E3 (the Viking "A pool" of industry).
At Garrington, this interbed is very thin, muddy and therefore
unproductive. The Garrington field, in contrast, is producing
from the stratigraphically lower coarse grained interval (VE4-
CM2), which directly overlies the VE4 surface.

abstract: Title: Sedimentology of the Viking Formation (Lower Cretaceous), Gilby A and B Fields, Alberta, Author: Holly K. Raddysh, Location: Thode

abstract:
Examination of 80 cores from the Viking Formation in
the Gilby A and B Field area allows sub-division into eleven
facies: 2 of which are predominantly mudstone, 2 fine to
medium grained sandstone facies, 2 laminated-burrowed
mudstone-sandstone facies, 2 pebbly sandstone facies, 2
conglomeratic facies and 1 facies (sideritized muddy
siltstone with Skolithos) which represents an erosional or
scoured surface. Trough cross-bedding is the dominant
sedimentary structure preserved in the sandy facies. Low
angle trough cross-bedding is observed in the pebbly
sandstone facies. The conglomeratic facies lack
stratification. Sandstone and conglomeratic facies are
referred to as the Viking Formation "coarse sediment
package" which is enveloped with sharp contacts by
underlying siltstones and overlying mudstones.

Both lateral and vertical variation of the facies
sequence occur over the Gilby A and B fields. The Gilby A
field may be delineated into 3 facies assemblages and the
Gilby B field as 1 facies assemblage. The vertical
variation in facies sequence of the coarse sediment package
is observed across the width of the Gilby A and B fields,
where 1 to 3 coarsening-upward sequences are observed.

Detailed study of log markers (using 450 logs) and
facies variations throughout the study region has revealed a
scour beginning along the southwestern margin of the Gilby A
and B fields. This scour surface is coincident with the lower surface of the coarse sediment package - represented
by a chert pebble veneer to the southeast of the fields.
The surface is also coincident with the sideritized muddy
siltstone (with Skolithos) facies (immediately underlying
the pebble veneer) found to the south and along the
southwest margins of the fields, although the scour has
removed this facies to the northwest. The scour surface
drops stratigraphically towards the northeast margin of the
fields and gently rises stratigraphically approximately
4.8-6.4 km beyond the northeastern margin of the fields.

The development of this scoured surface is problematic.
A transgressive period or relative rise in sea level could
have eroded the shoreface (presuming the area was near the
shoreface) leaving the scoured topography. This topography
being subsequently infilled by the Viking coarse sediment
package during a regressive period or relative drop in sea
level. Conversely, a rapid drop in sea level could have
resulted in the development of the scoured topography. This
was followed by scour topography infilling during a
continued, though slower regression possibly under influence
of a longshore current system.

abstract: Title: Fuel Trajectories of Nuclear Reactors, Author: Jeremiah C. Osuwa, Location: Thode

abstract:
The fissile fuel inventory of an external stockpile that supplies
a nuclear reactor is shown to be characterised by time dependent mean
residence time of fuel in the core, the load factor for the reactor, and
the breeding gains. The time dependent forms of these parameters have
been considered and quantitative evaluations of the fissile fuel inventory
have been carried out. The results show the substantial potentials of
efficient reactors in extending the duration of fissile fuel for Nuclear
industries.

The inventory concept has also been extended to CANDU reactors and
the result clearly depicts the effect of a net fissile fuel consuming
system on the nuclear fuel reserves.

abstract: Title: Aspects of Picosecond Spectroscopic Studies, Author: David A. Paape, Location: Thode

abstract:
Two novel experiments have been designed to determine
spectroscopic parameters and distinguish radiationless energy
transfer mechanisms using the properties of mode-locked
lasers. A unique experiment to determine fine and hyperfine
energy level splittings was designed using the quantum beat
fluorescence technique with synchronous excitation by a
mode-locked laser. An intermolecular energy transfer process
was employed in an experiment which was designed to
evaluate the energy rates for internal conversion and
vibrational relaxation in the picosecond domain.

Towards the implementation of the designed experiments
a mode-locked c.w. dye laser was designed and constructed.
The operational characteristics of the laser were determined
and the laser's ability to perform the designed experiments
was evaluated. The laser, as designed, required further
modification to perform the spectroscopic experiment;
however, the laser was able to perform the energy transfer
experiment and gave indications that vibrational relaxation
is a much faster process than internal conversion, even when
both processes occur in the picosecond time domain.

title: Flat Leadership and the Church: Embracing Change in Leadership Structures

subject: flat leadership, church, structures, change, hierarchical, culture

abstract:
 Hierarchical leadership structures were once the primary paradigm for leadership in
the church. In a contemporary world where culture has shifted and the rise of the scepticism
of authority has eroded hierarchies, the church must embrace a new paradigm. Flat leadership
is a structure that is being embraced in both the secular world and the church. In this thesis
we interpret the shifts in culture and how they have altered the landscape of leadership. We
also assess flat leadership as an effective approach to leadership in response to our shifting
culture.

 Flat leadership is a biblical approach to leading. This thesis will engage with
Scripture and highlight its support for leading through a sharing of power and authority.
Finally, we offer some thoughts on how to begin to move churches from hierarchies to flat
structures. Flat leadership represents a Biblical approach to church organizational structures.
Utilizing this approach can help churches avoid many of the common pitfalls of ministry and
can promote healthier structures for congregational life to thrive.

abstract:
 Churches have often struggled to nurture mature and lasting faith among their young
people. This is generally due to a lack of understanding about how beliefs form in adolescents
and therefore the ability to shape ministry accordingly. This thesis proposes that adolescents
form and mature their beliefs by interpreting significant life experiences. This thesis also offers suggestions for the practice for ministry based upon this understanding of belief formation. These suggestions are intended for church-based youth ministries and draw in part upon practices observed in summer camp ministries.
