    The film, Heaven is a Place, received funding from The Culture Programme of the European Union, and The Humanities, Music and Performing Arts Research Centre (HuMPA) at University of Plymouth; with additional grant funding from The ICCI Support Fund, Innovation for the Creative and Cultural IndustriesThrough a discussion of a local, movement-based performance for and through digital video, this chapter draws upon a range of scholarly dis- ciplines (including performance studies, film studies, somatics, queer studies, urban studies and human geography) from the perspective of practitioner-researchers to re ect upon the implications and potentials of a community lmmaking practice that is simultaneously aesthetic, political, spatial and social. In particular, it considers how the process-driven triangulation of thinking bodies, sexual subjectivities and emplacement within such a practice might enable us to acknowledge, consolidate and reimagine a community that had been either erased or marginalised in dominant accounts of its city. Heaven Is a Place is a short dance film, made in 2014 by the authors of this chapter in collaboration with members of the lesbian, gay, bisexual and trans (LGBT) community in Plymouth in South West England. Filmed in some of Plymouth’s most visually spectacular, evocative and liminal waterside locations – its docksides, marinas, look-out points, cruising spots, clubs and bathing areas – it explores becoming, melan- choly and the erotics of place through the human geography of an ‘ocean city’. In addition to choreography arising from site-responsive physical vocabularies, the film features scenarios and movement scores that reflect personal memories and queer histories of the city, developed in the first instance through a series of movement workshops that were co-organised with the LGBT advocacy organisation, Pride in Plymouth

    Band-to-band transitions, selection rules, effective mass and exciton binding energy parameters in monoclinic \beta-Ga2O3

    We employ an eigen polarization model including the description of direction dependent excitonic effects for rendering critical point structures within the dielectric function tensor of monoclinic \beta-Ga2O3 yielding a comprehensive analysis of generalized ellipsometry data obtained from 0.75 eV--9 eV. The eigen polarization model permits complete description of the dielectric response, and we obtain single-electron and excitonic band-to-band transition anisotropic critical point structure model parameters including their polarization eigenvectors within the monoclinic lattice. We compare our experimental analysis with results from density functional theory calculations performed using a recently proposed Gaussian-attenuation-Perdue-Burke-Ernzerhof hybrid density functional, and we present and discuss the order of the fundamental direct band-to-band transitions and their polarization selection rules, the electron and hole effective mass parameters for the three lowest band-to-band transitions, and their exciton binding energy parameters, in excellent agreement with our experimental results. We find that the effective masses for holes are highly anisotropic and correlate with the selection rules for the fundamental band-to-band transitions, where the observed transitions are polarized closely in the direction of the lowest hole effective mass for the valence band participating in the transition

    Role of material properties and mesostructure on dynamic deformation and shear instability in Al-W granular composites

    Full text link
    Dynamic experiments with Al-W granular/porous composites revealed qualitatively different behavior with respect to shear localization depending on bonding between Al particles. Two-dimensional numerical modeling was used to explore the mesomechanics of the large strain dynamic deformation in Al-W granular/porous composites and explain the experimentally observed differences in shear localization between composites with various mesostructures. Specifically, the bonding between the Al particles, the porosity, the roles of the relative particle sizes of Al and W, the arrangements of the W particles, and the material properties of Al were investigated using numerical calculations. It was demonstrated in simulations that the bonding between the "soft" Al particles facilitated shear localization as seen in the experiments. Numerical calculations and experiments revealed that the mechanism of the shear localization in granular composites is mainly due to the local high strain flow of "soft" Al around the "rigid" W particles causing localized damage accumulation and subsequent growth of the meso/macro shear bands/cracks. The "rigid" W particles were the major geometrical factor determining the initiation and propagation of "kinked" shear bands in the matrix of "soft" Al particles, leaving some areas free of extensive plastic deformation as observed in experiments and numerical calculations.Comment: 10 pages, 14 figures, submitted to Journal of Applied Physic

    Measurements of Intensity and Scale of Wind-Tunnel Turbulence and Their Relation to the Critical Reynolds Number of Spheres

    The investigation of wind-tunnel turbulence, conducted at the National Bureau of Standards with the cooperation of the National Advisory Committee for Aeronautics, has been extended to include a new variable, namely, the scale of the turbulence. This report presents the results of a study of this new variable together with the intensity of the turbulence, and the effect of both on the critical Reynolds number of spheres
