    This study evaluated skin tolerance and other properties relating to wear time, such as conformability and comfort, pain on dressing removal, adhesion and premature detachment, of four advanced hydrated dressings applied to the knees and elbows of 22 healthy volunteers over a fixed five-day period. The dressings all incorporate silicone-based adhesives and are designed to provide a moist wound environment while managing exudate. Skin tolerance was good for all four dressings but there was variation in regards to wear time and fluid-handling properties. Conflict of interest: this work was supported by a grant from Mölnlycke Health Care, Swede

    Baker's conjecture for functions with real zeros

    Get PDF
    Baker's conjecture states that a transcendental entire functions of order less than 1/2 has no unbounded Fatou components. It is known that, for such functions, there are no unbounded periodic Fatou components and so it remains to show that they can also have no unbounded wandering domains. Here we introduce completely new techniques to show that the conjecture holds in the case that the transcendental entire function is real with only real zeros, and we prove the much stronger result that such a function has no orbits consisting of unbounded wandering domains whenever the order is less than 1. This raises the question as to whether such wandering domains can exist for any transcendental entire function with order less than 1. Key ingredients of our proofs are new results in classical complex analysis with wider applications. These new results concern: the winding properties of the images of certain curves proved using extremal length arguments, growth estimates for entire functions, and the distribution of the zeros of entire functions of order less than 1

    Hyperbolic dimension of Julia sets of meromorphic maps with logarithmic tracts

    Full text link
    We prove that for meromorphic maps with logarithmic tracts (e.g. entire or meromorphic maps with a finite number of poles from class B\mathcal B), the Julia set contains a compact invariant hyperbolic Cantor set of Hausdorff dimension greater than 1. Hence, the hyperbolic dimension of the Julia set is greater than 1.Comment: 7 pages, 1 figur

    Romney Marsh: Evolution of the Historic Landscape and its Wider Significance

    © Oxford University School of Archaeology and the individual authors, 2002. Reproduced with permission of the publisher.Romney Marsh is one of the largest coastal wetlands in Britain, and has seen a long history of archaeological, documentary and geomorphological research. Recently, this has been complemented by interdisciplinary work of the Romney Marsh Research Trust's members, and we now have an extensive body of data relating to this remarkable landscape. In the first monograph produced by the Romney Marsh Research Trust, Christopher Green attempted a broad palaeogeographical reconstruction of how the Marsh may have evolved over the past 2,000 years, and this paper is an attempt to expand upon the model put forward. Some aspects of the wider significance of the history of Romney Marsh are then considered, including the importance of breaches in coastal barriers in affecting human utilisation of marshland landscapes, the significance of the associated estuaries for integrating coastal and inland economies, and the role of marshland within complex medieval estate structures
