Pressure distribution of a twin-engine upper-surface blown jet-flap model

An investigation has been made to determine the chordwise and spanwise pressure distributions of a small-scale upper-surface blown jet-augmented flap STOL model. The model was powered by two simulated high-bypass-ratio turbofan engines mounted ahead of and above an unswept-untapered wing in a nacelle having a rectangular nozzle. The results of the investigation are presented as tabulated and plotted chordwise pressure distribution coefficients for nine spanwise stations

Fertility control as a means of controlling bovine tuberculosis in badger (Meles meles) populations in south-west England: predictions from a spatial stochastic simulation model

A spatial stochastic simulation model was used to assess the potential of fertility control, based on a yet-to-be-developed oral bait-delivered contraceptive directed at females, for the control of bovine tuberculosis in badger populations in south-west England. The contraceptive had a lifelong effect so that females rendered sterile in any particular year remained so for the rest of their lives. The efficacy of fertility control alone repeated annually for varying periods of time was compared with a single culling operation and integrated control involving an initial single cull followed by annually repeated fertility control. With fertility control alone, in no instance was the disease eradicated completely while a viable badger population (mean group size of at least one individual) was still maintained. Near eradication of the disease (less than 1% prevalence) combined with the survival of a minimum viable badger population was only achieved under a very limited set of conditions, either with high efficiency of control (95%) over a short time period (1-3 years) or a low efficiency of control (20%) over an intermediate time period (10-20 years). Under these conditions, it took more than 20 years for the disease to decline to such low levels. A single cull of 80% efficiency succeeded in near eradication of the disease (below 1% prevalence) after a period of 6-8 years, while still maintaining a viable badger population. Integrated strategies reduced disease prevalence more rapidly and to lower levels than culling alone, although the mean badger group size following the onset of control was smaller. Under certain integrated strategies, principally where a high initial cull (80%) was followed by fertility control over a short (1-3 year) time period, the disease could be completely eradicated while a viable badger population was maintained. However, even under the most favourable conditions of integrated control, it took on average more than 12 years following the onset of control for the disease to disappear completely from the badger population. These results show that whilst fertility control would not be a successful strategy for the control of bovine tuberculosis in badgers if used alone, it could be effective if used with culling as part of an integrated strategy. This type of integrated strategy is likely to be more effective in terms of disease eradication than a strategy employing culling alone. However, the high cost of developing a suitable fertility control agent, combined with the welfare and conservation implications, are significant factors which should be taken into account when considering its possible use as a means of controlling bovine tuberculosis in badger populations in the UK

The sublime now.

The Sublime now is a collection of essays dealing with the sublime in contemporary theory, culture and society. It includes papers by internationally renowned authors from the UK, America and Europe alongside the new voices of younger academics. The contributors were: Jane Bennett, Mark Bould, Eu Jin Chua, Gudrun Filipska, Cornelia Klinger, Esther Leslie, William McDonald, Laura Mulvey, Claire Pajaczkowska, Griselda Pollock, Gene Ray, Bettina Reiber, Jan Rosiek, Sherryl Vint, and Luke White. Research Questions: The book critically examines the legacy of the sublime in contemporary art, culture and society and sets out to assess the value and dangers of this concept as it is articulated in its current resurgence in thought and practice. Research Context: The book situates itself in a recent trans-disciplinary resurgence of interest in the notion of the sublime. It includes essays whose approaches come from aesthetics and ethics, ecological and political thought, psychoanalysis, feminism, film studies, literary studies, art history and popular culture. It sets out to critically reflect on, as well as contribute to this growing discourse. Its particular focus is around the visual. The collection’s origins were in a two-day conference at the Tate Britain, organised by research staff and students at Middlesex University and the London Consortium. The book selected from the papers delivered at the conference and also added other essays not presented at the conference. Findings: The book identifies key issues and themes which surround the contemporary articulation of the sublime: ecological debates and current attitudes to nature; globalisation and to the recent politics of terror; current reappraisals of Kantian thought; contemporary art and its intertwinement with legacies stretching back to the Baroque; the aesthetics of cinema. It discovers the sublime as a concept closely bound into contemporary debates around popular culture, gender, the body, nature, violence, politics and globalised capitalism. The sublime is a complexly ambivalent category which on the one had points us beyond debates of the postmodern, but which is also implicated in the ideologies of contemporary society

A Study of Optical Observing Techniques for Extra-Galactic Supernova Remnants: Case of NGC 300

We present the results of a study of observational and identification techniques used for surveys and spectroscopy of candidate supernova remnants (SNRs) in the Sculptor Group galaxy NGC 300. The goal of this study was to investigate the reliability of using [Sii]/Halpha > 0.4 in optical SNR surveys and spectra as an identifying feature of extra-galactic SNRs (egSNRs) and also to investigate the effectiveness of the observing techniques (which are hampered by seeing conditions and telescope pointing errors) using this criterion in egSNR surveys and spectrographs. This study is based on original observations of these objects and archival data obtained from the Hubble Space Telescope which contained images of some of the candidate SNRs in NGC 300. We found that the reliability of spectral techniques may be questionable and very high-resolution images may be needed to confirm a valid identification of some egSNRs.Comment: 27 Figures, 10 table

Equilibrium of Land Values from Agricultural and General Economic Factors for Cropland and Pasture Capitalization in Georgia

Nonagricultural factors impact land values to cause a divergence of discounted cash rents for agricultural land and land values in Georgia. General economic factors are represented by per capita income in nonmetro areas. Cash rents for cropland and pasture have positive impacts on land values. Nonagricultural factors are stronger influences on land values than are cash rents. Greater effective demand exists for pasture than for cropland because pasture is subject to relatively more pricing pressure in northern counties with higher incomes and population. Increased land values have led to increased net wealth for Georgia agricultural producers.capitalization, cash rent, cointegration, equilibrium, error correction mechanism, land values, Land Economics/Use,
