Established-Outsider Relations and the Socio-Genesis of the Museum
It is surprising that little research has been conducted by Eliasians on museums and that, with some exceptions, academics working on museums do not cite The Civilizing Process. All the more so given that: (i) museum research supports Elias’s claim that elements of modernity originated in court societies, (ii) the nineteenth-century museum was a leading edge of the West’s belief in itself as a singularly civilized place and (iii) there is a contradiction between the museum’s universalism and its latent capacity to stigmatize some visitors as uncivilized outsiders. Indeed, Elias’s theory of established-outsider relations offers profound insights into the museum dimension of social stigma and the socio-genesis of the museum. First, an Eliasian perspective illuminates the relationship between museums and the peculiar structures of feeling that flowed from the interdependencies of modernization. Secondly, in studying European upper classes, he stressed the co-existence of different propertied strata within nineteenth-century states. This explains the apparent inchoateness of European national museums as they emerged at the interface of ruling dynastic elites and upwardly mobile bourgeois outsiders. Thirdly, documentary evidence reveals the museum to be a place where middle class people incorporated and transformed a courtly habitus whilst simultaneously stigmatizing both aristocratic and working class ways of living the body. Finally, Elias elaborated dynamic models of established-outsider relations, emphasizing their ‘complex polyphony’ as the key to explaining the power to stigmatize. The museum performed that polyphony at the interface of established-outsider relations; it could be said that they were the very causes of museums

Numerical Simulation for Droplet Combustion Using Lagrangian Hydrodynamics
A predictive model of spray combustion must incorporate models for the wide variety of physical environments in a practical combustor. In regions where droplets are closely spaced, combustion resembles a diffusion flame; where they are well separated, an envelope or wake flame results. The relative velocity field between the fuel droplets and oxidizer in influences boundary layer development about the droplet, recirculating flow patterns, and droplet shape and stability. A model must encompass these interacting temporal and spatial effects as well as complicated combustor boundaries. The objective of the current work is to develop the triangular gridding method for describing the individual and collective properties of vaporizing and burning fuel droplets
A survey of stellar X-ray flares from the XMM-Newton serendipitous source catalogue: Hipparcos-Tycho cool stars
The X-ray emission from flares on cool (i.e. spectral-type F-M) stars is
indicative of very energetic, transient phenomena, associated with energy
release via magnetic reconnection. We present a uniform, large-scale survey of
X-ray flare emission. The XMM-Newton Serendipitous Source Catalogue and its
associated data products provide an excellent basis for a comprehensive and
sensitive survey of stellar flares - both from targeted active stars and from
those observed serendipitously in the half-degree diameter field-of-view of
each observation. The 2XMM Catalogue and the associated time-series
(`light-curve') data products have been used as the basis for a survey of X-ray
flares from cool stars in the Hipparcos Tycho-2 catalogue. In addition, we have
generated and analysed spectrally-resolved (i.e. hardness-ratio), X-ray
light-curves. Where available, we have compared XMM OM UV/optical data with the
X-ray light-curves. Our sample contains ~130 flares with well-observed
profiles; they originate from ~70 stars. The flares range in duration from ~1e3
to ~1e4 s, have peak X-ray fluxes from ~1e-13 to ~1e-11 erg/cm2/s, peak X-ray
luminosities from ~1e29 to ~1e32 erg/s, and X-ray energy output from ~1e32 to
~1e35 erg. Most of the ~30 serendipitously-observed stars have little
previously reported information. The hardness-ratio plots clearly illustrate
the spectral (and hence inferred temperature) variations characteristic of many
flares, and provide an easily accessible overview of the data. We present flare
frequency distributions from both target and serendipitous observations. The
latter provide an unbiased (with respect to stellar activity) study of flare
energetics; in addition, they allow us to predict numbers of stellar flares
that may be detected in future X-ray wide-field surveys. The serendipitous
sample demonstrates the need for care when calculating flaring rates.Comment: 26 pages, 24 figures. Additional tables and figures available as 4

Numerical simulations of fuel droplet flows using a Lagrangian triangular mesh
The incompressible, Lagrangian, triangular grid code, SPLISH, was converted for the study of flows in and around fuel droplets. This involved developing, testing and incorporating algorithms for surface tension and viscosity. The major features of the Lagrangian method and the algorithms are described. Benchmarks of the algorithms are given. Several calculations are presented for kerosene droplets in air. Finally, extensions which make the code compressible and three dimensional are discussed
Physical and hydrodynamic characteristics of a dairy shed waste stabilisation pond system
Waste stabilization pond systems are widely used to treat animal wastes under highly variable hydraulic loading regimes. These systems have received limited research attention with regard to their hydrodynamic behaviour and the potential impact of shock hydraulic loading on their performance. In this study a two-stage dairy shed waste stabilisation pond system was topographically surveyed to determine the physical shape and the theoretical hydraulic retention time (HRT) of each pond, as well as the extent of sludge accumulation in the primary pond. The primary pond was then subjected to a series of drogue tracking runs whereby weighted floating survey targets with submerged âsailsâ were tracked during their movement through the pond at times of peak flow in order to characterise the hydrodynamic behaviour of the pond. The full capacity volumes of the primary and secondary ponds were calculated to be 1285m3 and 2391m3, respectively. Sludge had been accumulating in the primary pond at a rate of 0.73m3/d over a period of 2.4 years and this has reduced the active treatment volume of the pond to 657m3. Based on mean outflow, the HRTs of the ponds were 40 d and 137 d, respectively. The drogue runs revealed a vortexlike mixing pattern within the pond with higher velocities around the perimeter of the pond between the inlet and outlet, and lower velocities in the centre of the pond. In-pond velocities seemed relatively high in comparison with those from other drogue studies of larger ponds and the surging inflow caused the formation of a flow âjetâ that potentially contributed to significant short-circuiting. The range of influence of this flow jet, however, was limited to within 15m of the inlet, suggesting that short-circuiting would be likely to occur only under certain high inflow conditions
