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

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

Writing rape, troping history : story, plot, and ethical reading in Julia Franck's 'Die Mittagsfrau' (2007)

This article examines the rhetorical function of sexual violence in Julia Franck’s novel 'Die Mittagsfrau' (2007), which unflinchingly relates the degradations to which the protagonist is subjected from infancy: sexual exploitation by her sister; psychological abuse at the hands of her mother; sexual harassment by a family friend; abuse by her eventual husband; marginalization as a “Mischling” in the Third Reich; gang rape by Soviet soldiers. Franck extensively and graphically describes individual episodes of sexual harrassment within chapters that span several years. This narrative excess warrants a “hysterical reading” that magnifies textual details in order to demonstrate the link between representations of sexual violence and wider patterns of structural and symbolic violence. The gaps and tensions that emerge as the narrative shifts between the mimetic and tropological levels provide the basis for a broader exploration of the ethics of reading and the ethics of representing sexual violence more generally
