Comparing two athletic recovery positions between maximum effort training intervals
No full textRecovery is an extremely important component of successful exercise and fitness both on the sports field, and throughout the life course. Fitness enthusiasts and athletes understand the importance of utilizing specific training regimes to realize optimal performance. Throughout time spent as coaches of various types and levels of sport, the authors have observed a consistent clash between common recovery positions recommended by coaches to their athletes: hands behind head (HBH), and hands on knees (HOK). As a coach or trainer, comprehension of how the body works when it comes to exercise recovery is imperative, because it allows them to tap more deeply into the athletic potential of their pupils. We will explore the functionality of HBH and HOK recovery positions using a slightly modified version of the classic Wingate Anaerobic Test (WAnT). It will incorporate a 30 second sprint followed by a 180 second HOK or HBH recovery period‚ work to rest ratio of 1:6‚ and one additional 30 second round of sprint style exercise following said recovery period.

Nutation in the spinning Synchronized Position-Hold, Engage, Reorient Experimental Satellites spacecraft and fluid slosh
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2010.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student submitted PDF version of thesis.Includes bibliographical references (p. 103-106).Spacecraft today are often spin-stabilized during a portion their launch or mission. Though the basics of spin stabilization are well understood, there remains uncertainty in predicting the likelihood of rapid nutation growth due to onboard liquids. Solely analytical methods of prediction are mainly unsuccessful and physical tests to gather slosh data have only been done for a few specific spacecraft. Data from past spacecraft is subject to a number complex physical factors and anomalies during the launch or mission. This study verifies a ground based method to test fluid tanks horizontally and obtain the first fundamental frequency of the tank. Horizontal tanks have the gravitational acceleration vector applied in the same direction as the acceleration experienced by an offset tank on a spinning spacecraft. The study also performs tests on the Synchronized Position-Hold, Engage, Reorient Experimental Satellites (SPHERES) satellites to characterize their nutation. In the tests, the satellite is spun about a single axis and then allowed to drift. Each principal axis is tested by at least one test. Two configurations of the satellite are tested: the satellite by itself and the satellite with an additional rigid mass attached to alter the inertia matrix of the system. These two efforts can be combined in the future to perform spinning slosh testing on the SPHERES satellites, with knowledge of the frequency of the fluid tanks. The potential for the SPHERES Testbed to add to the generic fluid slosh data is due to it having a relatively simple spacecraft system capable of both software and hardware modifications and being located in the visually observable microgravity environment of the International Space Station (ISS).by Caley Ann Burke.S.M
The influence of historical forestry practices and climate on the sediment retention function of wetlands.
No full textWetlands provide beneficial functions and services (e.g. sediment retention, nutrient sequestration) to downstream aquatic environments. The resiliency of these functions under disturbance conditions is, however, not fully understood. Two wetland-lake systems (Boswell and Viewland) in the central interior of British Columbia whose contributing catchments have historically been impacted by forestry practices were selected to examine how wetland sediment retention responds to disturbance. Core chronologies and sedimentation rates were calculated from unsupported Pb measurements using the Constant Rate of Supply (CRS) model, and sediment source contributions were determined using a multivariate unmixing model, for both wetlands and their downstream lakes. Sedimentation rates did not significantly change post-logging in either lake however, the dominant source to Viewland Lake changed from channel bank material to subsurface material. The increase in the proportion subsurface material consistent with increase in dry density and magnetic susceptibility, and decreases in median grain size and C:N. The bordering wetland was not found to contain any material other than channel bank material. The ephemeral nature of the wetland channel, as well as the length of the channel and the significant decrease in median grain size are thought to have prevented sediment deposition, or increased the potential for resuspension and further transport. Sedimentation rates were greatest near the inflow of Boswell wetland, however, the strongest responses to forestry practices were observed near the wetland outflow. Similarly significantly lower median grain sizes could have limited deposition in the upstream areas of the wetland. Increases in precipitation as snow and stream discharge in addition to effects associated with forestry practices are thought to have been responsible for driving sedimentation rates in both catchments however, changes in source contributions were likely the result of active forestry practices. --P. ii.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b175500
Pilot evaluation of a web-based intervention targeting sexual health service access
No full textSexual health service access is fundamental to good sexual health, yet interventions designed toaddress this have rarely been implemented or evaluated. In this paper, pilot evaluation findingsfor a targeted public health behavior change intervention, delivered via a website and web-app,aiming to increase uptake of sexual health services amongst 13 to 19 year-olds are reported. Apre-post questionnaire-based design was used. Matched baseline and follow-up data wasidentified from 148 respondents aged 13-18 years. Outcome measures were self-reported serviceaccess, self-reported intention to access services, and beliefs about services and service accessidentified through needs analysis. Objective service access data provided by local sexual healthservices was also analyzed. Analysis suggests the intervention had a significant positive effect onpsychological barriers to and antecedents of service access amongst females. Males, whoreported greater confidence in service access compared with females, significantly increasedservice access by time 2 follow-up. Available objective service access data supports the assertionthat the intervention may have led to increases in service access. There is real promise for thisnovel digital intervention. Further evaluation is planned as the model is licensed to and rolled outby other local authorities in the UK.

Built Orders of Finance, Risk, and Racial Capitalism
No full textThis issue of ATR considers numerous instances in which economic historians and historians of capitalism have turned to architecture as evidence of the workings of economic and financial systems. This collective position paper stems from the attempt to engage more directly with these disciplines; an attempt that was first manifested in the symposium “Built Orders of Finance, Risk and Racial Capitalism,” held online in early 2022. How are built orders shaped by processes of financialization, actuarial calculations of risk and the conditions of racial capitalism? How do built orders mobilize specific economic regimes? What kinds of evidence can be enlisted to discern the constitutive relationships established and maintained between architecture and regimes of finance? What scales are implied in these relationships? What is involved in their historicization? This article invites future conversations between the fields of scholarship it canvases to more comprehensively apprehend the terms, conditions, and histories of financialized space.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Situated Architectur
