    The Brixton Deverill-East Knoyle d i s t r i c t lies at the western endof Salisbury Plain and encompasses the north-western part of the Vale of Wardour. The central part of the d i s t r i c t forms part of a dissected plateau developed on Upper Chalk (Figure 1); this reaches a maximum height of 238 m south-east of Brixton Deverill. In the north-west, there are prominent escarpments capped by the Lewes Chalk on either side of the Wylye valley. In the south, the Mere Fault and associated monoclinal structure play an important part in shaping the landscape. In the west, the chalk rises steeply on the north side of the fault from the clay vale to the south. Between West Knoyle and East Knoyle, the steeply dipping Upper Greensand and Chalk strata give rise to strongly featured ground. The principal drainage in the northern part of the d i s t r i c t is northwards by the River Wylye, the only permanent river on the chalk outcrop and its tributaries. In the south-central area, drainage is eastwards by a series of valleys that coalesce just west of Hindon and ultimately join the River Nadder at Tisbury. In the south, on the clay vale, drainage is southwestwards by tributaries of the River Lodden, and south-eastwards by tributaries of the River Nadder. The lowest point in the d i s t r i c t , c.96 m OD, lies in the southern tract. Soils developed on the Upper Greensand and most of the Chalk are light and w e l l drained. However, s o i l s on the West Melbury Chalk, together with some on the clay-with-flint deposits and Kimmeridge Clay are much heavier and poorly drained. Agriculture is a mixture of arable and pasture, with the latter dominant on the Kimmeridge Clay Vale. There are few woods, with deciduous woods confined mostly to the clay vale and the relatively newly planted coniferous plantations on the Chalk and Upper Greensand. Agriculture is the only industry in the area

    Tinea pedis: diagnosis and management

    No full text
    Tinea pedis is one of the most commonly encountered foot infections. The fact that in most cases it is easily treatable yet still prevalent in the general population suggests it is often undiagnosed or remains untreated by health care professionals and patients. The most common agent is Trichophyton rubrum which is often mistaken for dry skin in its presentation. Treatment should include curative as well as preventative measures where possible

    Dialogical Interspecies Ethics: Ataraxia, Desire and Hope in the Post-Human World of Anne Carson\u27s Pastoral

    This review essay implicitly revisits human and non-human power relations within a critical animal studies context that understands the affective conjunction between the manipulation of our worlds (action, partly through knowledge) and degrees of involvement with these others that live in our worlds (comportment via emotions). I take Louise Westling’s new study as the platform for an analysis of two book-length poems, The Autobiography of Red (1998) and red doc\u3e (2013), which centre on the life of a shepherd, Geryon. Rather than revisit classical pastoral, these texts extract power-relations that classical myth and pastoral spatialise. In so doing, I argue, they reclaim a site of the emotions within the scene of herding—itself a metaphor for containing animals, for channelling and managing resources, wildness. Carson’s treatment of emotions positions the reader to evaluate the border between human and non-human animals; to unpack and complicate the terms by which we might wish to make or unmake that very demarcation

    Towards The Sustainable City: The Impact Of Transport-Land Use Interactions, Deliverable 6. The Final Report.

    Very few transport studies have been able to demonstrate that transport policy measures alone can improve sustainability by reducing fuel consumption and emissions below existing levels. There is therefore an increasing interest in the use of coordinated transport-land use policies, but a lack of understanding of relevant relationships. This research sought to obtain greater insight into these relationships. The main objectives were: (i) to increase our understanding of the impact of accessibility and environmental quality on individuals’ and firms’ location decisions; (ii) to use the findings of (i) to enhance a newly developed strategic transport and land use interaction model; (iii) to use the enhanced model to assess the implications for urban sustainability of the impact of transport policy on location choice; and (iv) to use the enhanced model to assess the relative performance of different combinations of transport and land use strategy. There were two main strands to the work. The first involved the use of a newly developed strategic transport-land use model DELTA/START to test the effects of a range of values for environmental and accessibility coefficients. The tests were based on Edinburgh, and included several combinations of road pricing, fares reductions and light rail, and an alternative land use strategy. The second strand involved a literature review and survey work undertaken in Edinburgh using a stated preference approach to identify values for environmental indicators and accessibility to feed into the model. The survey work of households and businesses was successful in producing values for environmental quality and accessibility. We found that changes in air quality were valued more highly than corresponding changes in noise levels. The survey also revealed some interesting issues that merit further investigation: deteriorations in environmental quality were valued more highly than improvements, there was a greater resistance to increases in council tax beyond current levels than up to current levels and valuations were higher where conditions were worse. The transport strategies were predicted to induce considerable shifts in activity, with city centre populations increasing by up to 20%. However, these substantial changes in activity had relatively small impacts on the transport indicators. The results for the alternative land use scenario showed similar effects. Generally it appears, from the tests involving the strategic transport model that the effects on transport indicators of land use changes, whether induced through transport strategies or imposed through land use planning, are an order of magnitude lower than those of the transport strategies themselves. This is an important policy result since it calls into question how much can be achieved by pursuing coordinated land use and transport strategies

    Sensitivity analysis in computational aerodynamics

    Information on sensitivity analysis in computational aerodynamics is given in outline, graphical, and chart form. The prediction accuracy if the MCAERO program, a perturbation analysis method, is discussed. A procedure for calculating perturbation matrix, baseline wing paneling for perturbation analysis test cases and applications of an inviscid sensitivity matrix are among the topics covered
