    In this paper we present a portable magnetocardiography device. The focus of this development was delivering a rapid assessment of chest pain in an emergency department. The aim was therefore to produce an inexpensive device that could be rapidly deployed in a noisy unshielded ward environment. We found that induction coil magnetometers with a coil design optimized for magnetic field mapping possess sufficient sensitivity (104fT /√ Hz noise floor at 10Hz) and response (813fT /µV at 10Hz) for cycle averaged magnetocardiography and are able to measure depolarisation signals in an unshielded environment. We were unable to observe repolarisation signals to a reasonable fidelity. We present the design of the induction coil sensor array and signal processing routine along with data demonstrating performance in a hospital environment

    Self-organized current transport through low angle grain boundaries in YBa2_2Cu3_3O7δ_{7-\delta} thin films, studied magnetometrically

    Full text link
    The critical current density flowing across low angle grain boundaries in YBa2_2Cu3_3O7δ_{7-\delta} thin films has been studied magnetometrically. Films (200 nm thickness) were deposited on SrTiO3_3 bicrystal substrates containing a single [001] tilt boundary, with angles of 2, 3, 5, and 7 degrees, and the films were patterned into rings. Their magnetic moments were measured in applied magnetic fields up to 30 kOe at temperatures of 5 - 95 K; current densities of rings with or without grain boundaries were obtained from a modified critical state model. For rings containing 5 and 7 degree boundaries, the magnetic response depends strongly on the field history, which arises in large part from self-field effects acting on the grain boundary.Comment: 8 pages, including 7 figure

    Bench-to-bedside review: Amelioration of acute renal impairment using ethyl pyruvate

    Get PDF
    Inflammation and oxidative stress cause renal impairment. Renal failure exacerbates the effect of oxidative stress on many organ systems. Antioxidants can prevent or treat renal failure in various experimental models and clinical situations. Pyruvate is an endogenous antioxidant with beneficial effects in animal models of oxidative stress. Because sodium pyruvate rapidly degrades in solution, a simple derivative of pyruvic acid, namely ethyl pyruvate, has been investigated as a therapeutic agent in preclinical studies. Ethyl pyruvate reduces organ system damage in ischaemia/reperfusion injury and haemorrhagic and endotoxic shock, at least in part through its antioxidant action. In addition, ethyl pyruvate appears to have direct beneficial effects on cytokine expression and proinflammatory gene regulation. The effect is long lasting and, importantly, even when it is administered after the onset of inflammation it can ameliorate organ damage and improve survival. Ethyl pyruvate is a widely used as a food additive and was shown to be safe in phase I clinical trials. We suggest ethyl pyruvate warrants further evaluation in the management of acute renal impairment

    Consumer Perceptions Matter:A Case Study of an Anomaly in English Football

    Get PDF
    In 1983 England's fifth-tier football competition introduced a two-points-for-a-home-win and three-points-for-an-away-win reward system. This system was abolished after three seasons. The anomalous point system may have been introduced to reduce home advantage but the reasons are not fully clear and neither are the reasons for abolishing the system shortly after its introduction. We find that the new point system did not affect match outcomes but it did influence match attendance negatively. We speculate that the alternative point system was perceived as unfair to potential buyers of seasonal tickets or individual match tickets some of whom as a response decided to avoid watching the game in person. Consumer perceptions seem to matter.</p
