AX-5 space suit bearing torque investigation
The symptoms and eventual resolution of a torque increase problem occurring with ball bearings in the joints of the AX-5 space suit are described. Starting torques that rose 5 to 10 times initial levels were observed in crew evaluation tests of the suit in a zero-g water tank. This bearing problem was identified as a blocking torque anomaly, observed previously in oscillatory gimbal bearings. A large matrix of lubricants, ball separator designs and materials were evaluated. None of these combinations showed sufficient tolerance to lubricant washout when repeatedly cycled in water. The problem was resolved by retrofitting a pressure compensated, water exclusion seal to the outboard side of the bearing cavity. The symptoms and possible remedies to blocking are discussed
Bereavement after miscarriage: Implications for pastoral care.
This thesis explores the dilemma women experience when they have a miscarriage. The tension between their perception of its significance and the perception of those around them, create difficulties for them as they attempt to integrate the event into their life-pattern. The social and psychological setting for miscarriage, the dynamics of perinatal bereavement, and models of care are reviewed. The theological and philosophical background of dualistic attitudes towards women and their bodies is examined in the work of traditional and feminist theologians. An examination of the results of interviews with twenty women who had miscarried within the previous four years shows dramatically the tension and difficulties with integration. Some main factors that lead to a measure of integration are explained. The implications for pastoral care, based on the previous information and an analysis of pastoral care theory as it relates to bereavement, produces several concrete suggestions for changes in the type of pastoral care women who miscarry receive.Dept. of Religious Studies.

An analysis of northern goshawk prey preferences by biogeoclimatic subzone across coastal British Columbia
This thesis investigates the dietary preferences of northern goshawk populations
in second growth stands on Vancouver Island and the islands of the Johnstone Strait
region on the BC Mainland Coast. Prey abundance was inferred through the analysis of
pellets composed of regurgitated non-digested prey remains that were collected during
the annual survey monitoring program carried out by Mosaic Forest Management and
predecessor companies since 2012. The relative abundance of prey species was
compared across three Coastal Western Hemlock subzones (CWHvm1, CWHmm1,
CWHxm2) under the Biogeoclimatic Ecosystem Classification (BEC) system using the
Chi-square test. No significant correlations were found between prey species abundance
and BEC subzone (χ2 = 2.3, P = 0.32) in 2013 and (χ2 = 0.84, P = 0.66) in 2014. Trends
within the dataset indicate coastal northern goshawks on Vancouver Island and the BC
Mainland Coast show a general dietary propensity towards avian prey, which is
consistent with findings from other studies. The variation in prey abundance and species
diversity reported in this study is more likely a function of topography and forest
structure, season and region than it is to BEC subzones. Findings from this study
highlights how younger stands could be providing more suitable habitat than was
traditionally thought

Understanding Anthropological Understanding: for a merological anthropology
In this paper I argue for a merological anthropology in which ideas of ‘partiality’ and ‘practical adequacy’ provide a way out of the impasse of relativism which is implied by post-modernism and the related abandonment of a concern with ‘truth’. Ideas such as ‘aptness’ and ‘faithfulness’ enable us to re-establish empirical foundations without having to espouse a simple realism which has been rightly criticised. Ideas taken from ethnomethodology, particularly the way we bootstrap from ‘practical adequacy’ to ‘warrants for confidence’ point to a merological anthropology in which we recognize that we do not and cannot know everything, but that we can have reasons for being confident in the little we know
