MORE OpenChoice articles are open access and distributed under the terms of the Creative Commons Attribution License 3.0.The main component of the Surrey Dendrochronology Project is the accurate dating of 177 ‘dwellings’, nearly all by tree-ring analysis. The dates are used to establish date ranges for 52 ‘key features’, which cover many aspects of timber-framing from building type to details of carpentry. It is shown that changes of method and fashion were in many cases surprisingly rapid, almost abrupt in historical terms. Previous dating criteria for timber-framed dwellings in the county have been refined and new criteria introduced. Clusters of change from the 1440s and the 1540s are shown and some possible historical links suggested.The Heritage Lottery Fund, the Domestic Buildings Research Group (Surrey), the Surrey Archaeological Society and the historical societies of Charlwood, Farnham and Nutfield
Hepatic Metastasis via a Ventriculo-Peritoneal Shunt from an Intracranial Meningioma: Case Report and Review of the Literature
Meningiomas are slow-growing intracranial/intraspinal tumours, with a wide range of histopathological variants. The more aggressive atypical and malignant types can disseminate via the venous system, lymphatics or cerebrospinal fluid, with the lungs and pleura being the most common site of extracranial metastasis. We look at a 68-year-old woman presenting with abdominal pain, who had previously been treated for an intracranial meningioma with a ventriculo-peritoneal shunt in situ. Investigation revealed a lesion in segment 4 of the liver with the shunt tip being in close proximity. Biopsy was consistent with metastatic meningioma. A liver resection was subsequently performed. We postulate that this is the first reported case of dissemination of an intracranial meningioma via cerebrospinal fluid by means of a ventriculo-peritoneal shunt
The Effects of Various Recovery Techniques on Collegiate Pitching Performance
Snyder, B., Davis, S., Moir, G., Miltenberger, M., East Stroudsburg University, East Stroudsburg, PA
Purpose: This study was designed to compare pitching performance (velocity, accuracy), symptomology and functional movement across three recovery techniques (active recovery (pedaling on a stationary bike at 40% Max Age Predicted Heart Rate), passive recovery (sitting down with a jacket around the pitchers arm), and Electro muscular stimulation (sitting down with stim placed on the pitchers arm at the anterior and posterior deltoid) in NCAA Division II collegiate pitchers. Methods: Eight male Division II collegiate baseball athletes (Age: 20.1 ± 1.7 years, Mass: 84.8 ± 10.9 kg, average years of experience: 1.8 ± 1.3, % fat mass: 11.1 ± 4.9, Starter pitcher/relief pitcher: 4/4) volunteered to participate in this study. Each pitcher threw 15 pitchers per inning for a total of 45 pitches per session (3 Fastball, 1 Curveball, 1 Changeup-3 times per inning). After each inning pitched a recovery was performed for 6 minutes to simulate the time in between innings. Prior to warm up, after warm up and after each of the three innings was performed each pitcher was tested for HLa, delta pain scale, internal rotation, external rotation, overall RPE and local RPE. Results: The electro muscular stimulation showed significantly greater amount of strikes thrown at p \u3c 0.05. Overall the velocities (mph) were similar over all three recovery methods and all three innings thrown. Conclusion: Findings from this study suggest the importance of possibly implementing the use of electro muscular stimulation during pitchers recoveries times between innings. Since the velocity was not affected, different recovery methods may be useful to aid the accuracy of different individuals in game situations
Power corrections from decoupling of the charm quark
Decoupling of heavy quarks at low energies can be described by means of an
effective theory as shown by S. Weinberg in Ref. [1]. We study the decoupling
of the charm quark by lattice simulations. We simulate a model, QCD with two
degenerate charm quarks. In this case the leading order term in the effective
theory is a pure gauge theory. The higher order terms are proportional to
inverse powers of the charm quark mass starting at . Ratios of
hadronic scales are equal to their value in the pure gauge theory up to power
corrections. We show, by precise measurements of ratios of scales defined from
the Wilson flow, that these corrections are very small and that they can be
described by a term proportional to down to masses in the region of
the charm quark mass
Characterization of the spore surface and exosporium proteins of Clostridium sporogenes; implications for Clostridium botulinum group I strains.
Clostridium sporogenes is a non-pathogenic close relative and surrogate for Group I (proteolytic) neurotoxin-producing Clostridium botulinum strains. The exosporium, the sac-like outermost layer of spores of these species, is likely to contribute to adhesion, dissemination, and virulence. A paracrystalline array, hairy nap, and several appendages were detected in the exosporium of C. sporogenes strain NCIMB 701792 by EM and AFM. The protein composition of purified exosporium was explored by LC-MS/MS of tryptic peptides from major individual SDS-PAGE-separated protein bands, and from bulk exosporium. Two high molecular weight protein bands both contained the same protein with a collagen-like repeat domain, the probable constituent of the hairy nap, as well as cysteine-rich proteins CsxA and CsxB. A third cysteine-rich protein (CsxC) was also identified. These three proteins are also encoded in C. botulinum Prevot 594, and homologues (75-100% amino acid identity) are encoded in many other Group I strains. This work provides the first insight into the likely composition and organization of the exosporium of Group I C. botulinum spores

From Service to Experience: Understanding and Defining the Hospitality Business
Failure adequately to define or understand hospitality as a commercial phenomenon has created a fragmented academic environment and a schizophrenia in the industry that has the potential to limit its development as a global industry. This article suggests that, by redefining hospitality as behaviour and experience, a new perspective emerges that has exciting implications for the management of hospitality businesses. A framework to describe hospitality in the commercial domain is proposed. This framework suggests a focus on the host–guest relationship, generosity, theatre and performance, ‘lots of little surprises’, and the security of strangers – a focus that provides guests with experiences that are personal, memorable and add value to their lives
Critical States in Disordered Superconducting Films
When subject to a pair-breaking perturbation, the pairing susceptibility of a
disordered superconductor exhibits substantial long-ranged mesoscopic
fluctuations. Focusing on a thin film subject to a parallel magnetic field, it
is proposed that the quantum phase transition to the bulk superconducting
condensate may be preempted by the formation of a glass-like phase with
multi-fractal correlations of a complex order parameter. Although not
universal, we argue that such behavior may be a common feature of quantum
critical phenomena in disordered environments.Comment: 7 pages, 1 eps figur
