    A scrubber was required to abate a waste stream containing chlorine gas created in the electrolytic dissolution step of the aqueous polishing process at the Mixed Oxides Fuel Fabrication Facility at Savannah River Site, South Carolina. A method of absorption that utilized caustic sodium sulfite as the scrubbing agent was studied for implementation in the process. This method was found to be highly efficient with respect to process requirements, and it was also found to provide enhanced performance over the more conventional method of chlorine scrubbing which uses only aqueous sodium hydroxide as a reagent. Sulfite provides an additional advantage in that it scavenges other potential pollutants such as hypochlorite and prevents their desorption back into the gas stream. Absorption was found to be rate-limited by liquid phase mass transfer at low to medium sulfite concentrations. The process is believed to be rate-limited by gas phase mass transfer at higher sulfite concentrations, although specific conditions for gas phase control could not be determined. A significant amount of the sulfite was found to be consumed by an undesirable oxidation side reaction. The process was found to be mildly exothermic, but heat effects were not detrimental to system performance

    Cool Core Bias in Sunyaev-Zel'dovich Galaxy Cluster Surveys

    Sunyaev-Zeldovich (SZ) surveys find massive clusters of galaxies by measuring the inverse Compton scattering of cosmic microwave background off of intra-cluster gas. The cluster selection function from such surveys is expected to be nearly independent of redshift and cluster astrophysics. In this work, we estimate the effect on the observed SZ signal of centrally-peaked gas density profiles (cool cores) and radio emission from the brightest cluster galaxy (BCG) by creating mock observations of a sample of clusters that span the observed range of classical cooling rates and radio luminosities. For each cluster, we make simulated SZ observations by the South Pole Telescope and characterize the cluster selection function, but note that our results are broadly applicable to other SZ surveys. We find that the inclusion of a cool core can cause a change in the measured SPT significance of a cluster between 0.01% - 10% at z > 0.3, increasing with cuspiness of the cool core and angular size on the sky of the cluster (i.e., decreasing redshift, increasing mass). We provide quantitative estimates of the bias in the SZ signal as a function of a gas density cuspiness parameter, redshift, mass, and the 1.4 GHz radio luminosity of the central AGN. Based on this work, we estimate that, for the Phoenix cluster (one of the strongest cool cores known), the presence of a cool core is biasing the SZ significance high by ~ 6%. The ubiquity of radio galaxies at the centers of cool core clusters will offset the cool core bias to varying degrees.Comment: 8 pages, 4 figures, accepted to Ap

    Patterns of human awareness and action : an interpretation of Gandhi's world view in comparative perspective

    Get PDF
    Bibliography: leaves 236-249.This thesis is a study of the nature, construction, and operation of human world view systems. Using a comparative dialogue with Mahatma Gandhi, Leo Tolstoy, and Religious Studies I aim to develop a definition of world view that explores the pivotal world view universals of identity, orientation and belonging and how these combine and interact in world view systems. I also explore various possibilities of how a sense of identity arises within human awareness and how this in turn structures individuals' understanding of their vocations and modes of active engagement with the world. I hypothesise that this process of identity and world view formation occurs in two paradigmatically different ways which structure the totality of individuals thinking, feeling and acting in the world, whether they are psychologically integrated, and whether their socio-political interactions tend toward violence or nonviolence. Using the theoretical resources of the comparative study of mysticism and religious experience, I set out to define the precise analytical contours of my two paradigms of human awareness and world view. It is in fact the study of mysticism that enables one to more clearly understand what is simultaneously the most crucial and yet neglected facet of human psychology and existence - love. I therefore not only attempt to analyse the construction and operation of world view universals in Gandhi's world view, but also to reinterpret the pivotal Gandhian notions of unity, love, truth and nonviolence as they converge in a personal inner experience of faith. Theoretical resources which I develop, applied to case studies of Gandhi and Tolstoy, are combined to enable general reflections about the nature of conceptual functioning by means of conceptual models or maps, as well as the existential basis of personal empowerment in contexts of violence and death. This thesis confirms the importance of securing a sense of identity, orientation, and belonging - the tension between part and whole - in any world view system, but lays greater stress on the crucial psychological and existential need to overcome a sense of separation, which is a pivotal factor in distinguishing two broad possibilities of human awareness and action as well as two paradigms of world view. The possibility of overcoming the sense of separateness, I suggest, is perhaps the central existential factor determining whether human social interactions are basically violent or nonviolent. It is within the basically nonviolent paradigm of world view, identity and action that one can locate and so better understand Gandhi's religious world view at both its individual and corporate levels

    Understanding the female judoka’s “coach – athlete” relationship: a British perspective

    Get PDF
    Background and Study Aim: The initial idea for the investigation came from Maki Tsukada’s two year observation of the British system, but also after reflection on the London 2012 Olympics and the “coach – athlete” interaction. The wider impact of the study will mean that coaches will have a greater understanding of how to build and work at their relationship with their athletes and understand what the important dynamics are within. The purpose of this study was the knowledge about the “coach – athlete” relationship, to gain a greater understanding into the relationship between female judo athletes and their coach. Material and Methods: The participants chosen were the Women’s Great Britain Judo Squad 2013, the athletes (n = 36) and the National coaches (n = 2). The study explores what is felt as important, the dynamics in the relationship and does the athlete’s opinion differ from that of the coach. The athletes participated in a specifically designed questionnaire and the coaches in semi-structured interview. Results: The findings demonstrate the importance of the relationship and the varying, yet often similar attributes expressed, from both the athletes and coaches. Conclusions: The significant and fundamental finding was the importance of the “coach – athlete” relationship being recognised by both the athletes and the coaches, with the athletes declaring that they definitely need a coach to develop and improve. In a direct comparison on what is important to the athlete and to the coach in the dynamic of the relationship, the points are very similar

    Language and Being: Crossroads of Modern Literary Theory and Classical Ontology

    Get PDF
    My argument is that poststructuralist and postmodernist theory carries on and intensifies the main lines of a characteristically modern tradition of aesthetics whose most important point of reference is not French structuralism – as the term, ‘poststructuralism’, implies – but the tradition of 18th-century German romanticism and idealism that culminated in the work of Heidegger during the Weimar period in Germany between the world wars and afterward. What characterizes this modernist tradition of aesthetics is its valorization of language as a mode of being possessed of an ‘ontological’ status. I place the term ‘ontology’ in quotes in order to highlight the distinction between ‘metaphysics’, with its Aristotelian and neo-Platonic connotations of a ‘chain of being’, and the more modern term ‘ontology’, which was coined in the 17th century and which became widely used during the 18th century by Leibnizian philosophers Christian Wolff and Alexander Baumgarten; the latter, not incidentally, also helped to establish modern usage of the term ‘aesthetics’.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

    Development of a Low-Reynolds Number, Nonlinear kappa-epsilon Model for the Reduced Navier-Stokes Equations

    Previous work at NASA LeRC has shown that flow distortions in aircraft engine inlet ducts can be significantly reduced by mounting vortex generators, or small wing sections, on the inside surface of the engine inlet. The placement of the vortex generators is an important factor in obtaining the optimal effect over a wide operating envelope. In this regard, the only alternative to a long and expensive test program which would search out this optimal configuration is a good prediction procedure which could narrow the field of search. Such a procedure has been developed in collaboration with NASA LeRC, and results obtained by NASA personnel indicate that it shows considerable promise for predicting the viscous turbulent flow in engine inlet ducts in the presence of vortex generators. The prediction tool is a computer code which numerically solves the reduced Navier-Stokes equations and so is commonly referred to as RNS3D. Obvious deficiencies in RNS3D have been addressed in previous work. Primarily, it is known that the predictions of the mean velocity field of a turbulent boundary layer flow approaching separation are not in good agreement with data. It was suggested that the use of an algebraic mixing-length turbulence model in RNS3D is at least partly to blame for this. Additionally, the current turbulence model includes an assumption of isotropy which will ultimately fail to capture turbulence-driven secondary flow known to exist in noncircular ducts
