Boron neutron capture synovectomy (BNCS) is a potential application of the lʻB(n, a)7Li reaction for the treatment of rheumatoid arthritis via synovial ablation. This thesis has explored several aspects of effective neutron delivery for accelerator-based BNCS, which is currently under investigation at the Laboratory for Accelerator Beam Applications (LABA) at MIT. Monte Carlo methods were used to design and optimize a neutron moderator- reflector-target assembly. Treatment times for parallel-opposed irradiations, based on a 1 mA accelerator current and 1000 ppm of lʻB uptake in the synovium, range from 3-48 minutes, depending on the neutron source reaction and targeted joint. The behavior of the therapy parameters was quantified for ''ʻB uptake in the synovium up to 19,000 ppm; the minimum necessary concentration was shown to be a few hundred ppm. A dedicated BNCS neutron beamline was constructed and installed at LABA based on the Monte Carlo design. Dosimetry measurements in an in-beam reference phantom showed good overall agreement for the fast neutron, thermal neutron, and photon dose rates, validating the Monte Carlo predictions of the beamline performance.

The notion of place for me is symbolised by the trees of Franklinford. Furthermore, aspects of Heidegger''s philosophy of place are considered. Also, notions of time are explored in relation to the history of the site. The works of contemporary theorists are presented in relation to ideas of hybridity and postcolonialism. Central to the processes and themes of this body of work was the creation of the Sacred Wardrobe. This piece represents the environmental and cultural concerns that underpin this thesis. These concerns of place and the sacred are embodied in the notion of sanctuary. The physical manifestation of the sanctuary provides a sacred geography.

This dissertation describes three investigations of the dinuclear ruthenium complex, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)4: (1) its use as a catalyst for the hydroamination of alkynes by a new mechanism, (2) its reactions with H2 to give new ruthenium clusters containing bridging hydride ligands, and (3) the determination of thermodynamic and kinetic acidities of two related complexes [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)3[P(OR)3]HBF4− (R= Me, Ph). A fundamentally new mechanism for alkyne hydroamination catalyzed by the ruthenium complex, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)3(C2H4)H+BF4−, has been proposed. Many of the intermediates in the catalytic cycle have been isolated and/or characterized spectroscopically and found to react according to the proposed mechanism. The catalyst activity is terminated as a result of the isomerization of a bridging alkyne ligand in a key intermediate in the catalytic cycle. The butterfly cluster, [([eta]5-C5H3)2(SiMe2)2]2Ru4(CO)3H4, and the square planar cluster, [([eta]5-C5H3)2(SiMe2)2]2Ru4(CO)4H4, have been isolated from the photochemical reaction of H2 with the doubly-linked dicyclopentadienyl complex, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)4, in benzene. Wavelength-dependent photolysis studies suggest that the first step in the reaction of [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)4 with H2 involves metal-metal bond cleavage. The reaction of the protonated phosphite complexes, [([eta]5-C5H3)2(SiMe2)2]Ru2(CO)3[P(OR)3]H+BF4− (R= Me, Ph), with tertiary amines (DABCO, 4-methylmorpholine, NEt3, N(n-Bu)3) results in clean deprotonation of the metal-metal bond by the amine. Equilibrium measurements show that the P(OPh)3 complex is more acidic than the P(OMe)3 complex. The rates of deprotonation of the phosphite complexes have been determined and follow the rate law: Rate = k1[complex] + k2[amine][complex]. Comparisons of the k2 rate constants reveal that the reactions are much more sensitive to the steric properties of the amine and metal complex than to electronic factors.

During Integrated Ocean Drilling Program (IODP) Expedition Leg 308, many Whole Core Samples were recovered from the Ursa Basin in the Gulf of Mexico. Post-cruise geotechnical testing found these samples to be highly disturbed due to the sampling process. This research will determine mechanical properties of laboratory Resedimented samples created using recovered Leg 308 sediment. A seven triaxial compression tests, Ko consolidated, were performed to ascertain these mechanical properties as a function of consolidation stress. Consolidation stress for these specimen ranges from 150 kPa up to 1,200 kPa. Axial strain induced on the soil during laboratory consolidation was approximately 60%. Results show that with an increase in Ko values there is a decrease in undrained shear strength, which is in accord with research completed on resedimented Boston Blue clay (RBBC) at MIT and also intact material that was recovered from this expedition. Undrained shear strength of the material is between 0.24 and 0.27, which is weaker than what is expected, according to SHANSEP. Friction angle of the material ranges from approximately 220 to 260. There is not any apparent relationship between Ko and modulus, friction angle or consolidation stress. Reaching end of primary proved to be a difficult task, concluding that it is reached after approximately five days. CRS data was used to corroborate values such as Cv, (0.0004 cm2/sec) and to more clearly map compression behavior. The results will provide a data base perform analysis and design of offshore structures and calibrate soil models.

This thesis is an investigation of freelance translators from the perspective of both Translation Studies and Industrial/Organisational (I/O) Psychology. In it, we look at descriptive and inferential statistics from two samples - one of 43 participants based in New Zealand, and the second of 92 participants based in various countries. We also conducted ten interviews, in which participants explain their own experiences in detail. Purpose: The purpose is primarily to further understand the working lives of freelance translators, and secondly to understand how our theory of psychological skill relates to freelancers'' success in their work (both in objective and subjective terms). Psychological skill is made up of evaluations of participant self-efficacy, locus of control, and attributions of both negative and positive events, all of which demonstrate adaptive skill in dealing with professional challenges. We propose that psychological skill is an important link in the model of the relationship between job ability and motivation, job constraints, and subsequent job performance in translation. The whole project is nested within further work in the field of translator competence, combined with aspects of I/O Psychology. We also aim to provide a quantitative, descriptive snapshot of the translation industry both in New Zealand and overseas. Findings: We found that various key measures of professional success (e.g. income, job satisfaction, number of jobs per week) were positively correlated with key components of psychological skill. Furthermore, we were able to utilize ordinal regression models, containing a combination of work-related and psychological skill variables, to predict both translators'' income and job satisfaction. The descriptive statistics and interview data revealed much of interest about translators'' work profiles. Originality and value: This is, to the best of our knowledge, the first research project to approach the study the career profiles of freelance translators from a methodologically rigorous, quantitative perspective, combining numerical results with rich interview data. Its value is in terms of both description of translation as a career and as an industry, and in terms of possible training and education for both new and future translators. Using methodology from I/O Psychology also contributes an understanding of translator competence, complementing and building on existing competence models.
