Students Create \u27Flash Marketing\u27 Business Model

Some business students hope to succeed in their eventual careers and have little real-world experience before graduating. Three students from the Jon M. Huntsman School of Business have experienced success in business long before their degrees at USU are finished.https://digitalcommons.usu.edu/huntsman_news/1096/thumbnail.jp

Naval History by Conspiracy Theory: The British Admiralty before the First World War and the Methodology of Revisionism

Revisionist interpretations of British naval policy in the Fisher era claim that an elaborate smoke screen was created to hide the Royal Navy’s real policies; while documents showing the true goals were systematically destroyed. By asserting this, revisionists are able to dismiss those parts of the documentary record that contradict their theories, while simultaneously excusing the lack of evidence for their theories by claiming it has been destroyed. This article shows that this methodology is misleading and untenable

Serendipitous Kepler observations of a background dwarf nova of SU UMa type

We have discovered a dwarf nova (DN) of type SU UMa in Kepler data which is 7.0 arcsec from the G-type exoplanet survey target KIC 4378554. The DN appears as a background source in the pixel aperture of the foreground G star. We extracted only the pixels where the DN is present and observed the source to undergo five outbursts -- one a superoutburst -- over a timespan of 22 months. The superoutburst was triggered by a normal outburst, a feature that has been seen in all DNe superoutburst observed by Kepler. Superhumps during the super outburst had a period of 1.842+/-0.004 h and we see a transition from disc-dominated superhump signal to a mix of disc and accretion stream impact. Predictions of the number of DNe present in Kepler data based on previously published space densities vary from 0.3 to 258. An investigation of the background pixels targets would lead to firmer constraints on the space density of DN.Comment: Accepted for publication in MNRA

Gene transfer of tumor necrosis factor inhibitor improves the function of lung allografts

AbstractBackgroundTumor necrosis factor is an important mediator of lung transplant acute rejection. Soluble type I tumor necrosis factor receptor binds to tumor necrosis factor-α and -β and inhibits their function. The objectives of this study were to demonstrate efficient in vivo gene transfer of a soluble type I tumor necrosis factor receptor fusion protein (sTNF-RI-Ig) and determine its effects on lung allograft acute rejection.MethodsThree groups of Fischer rats (n = 6 per group) underwent recipient intramuscular transfection 24 hours before transplantation with saline, 1 × 1010 plaque-forming units of control adenovirus encoding β-galactosidase, or 1 × 1010 plaque-forming units of adenovirus encoding human sTNF-RI-Ig (Ad.sTNF-RI-Ig). One group (n = 6) received recipient intramuscular transfection with 1 × 1010 Ad.sTNF-RI-Ig at the time of transplantation. Brown Norway donor lung grafts were stored for 5 hours before orthotopic lung transplantation. Graft function and rejection scores were assessed 5 days after transplantation. Time-dependent transgene expression in muscle, serum, and lung grafts were evaluated by using enzyme-linked immunosorbent assay of human soluble type I tumor necrosis factor receptor.ResultsRecipient intramuscular transfection with 1 × 1010 plaque-forming units of Ad.sTNF-RI-Ig significantly improved arterial oxygenation when delivered 24 hours before transplantation compared with saline, β-galactosidase, and Ad.sTNF-RI-Ig transfection at the time of transplantation (435.8 ± 106.6 mm Hg vs 142.3 ± 146.3 mm Hg, 177.4 ± 153.7 mm Hg, and 237.3 ± 185.2 mm Hg; P = .002, .005, and .046, respectively). Transgene expression was time dependent, and there was a trend toward lower vascular rejection scores (P = .066) in the Ad.sTNF-RI-Ig group transfected 24 hours before transplantation.ConclusionsRecipient intramuscular Ad.sTNF-RI-Ig gene transfer improves allograft function in a well-established model of acute rejection. Maximum benefit was observed when transfection occurred 24 hours before transplantation

Inhibition of inducible nitric oxide synthase ameliorates rat lung allograft rejection

AbstractRecently, the inducible isoform of nitric oxide synthase has been shown to be an important immunomodulation molecule in allograft rejection. We have observed the production of nitric oxide during rejection and the effect of nitric oxide synthase inhibition on allograft rejection in a rat lung transplant model. Rat left lung allotransplants were performed in two strain combinations: brown Norway–to–F344 (major histocompatibility complex incompatible); and Lewis-to-F344 (minor loci incompatible) as severe and mild rejection models respectively. Syngeneic F344-to-F344 transplants were performed as a negative control. Nitric oxide production during rejection was determined by measuring the recipient's serum nitrite/nitrate levels as a stable end product of nitric oxide. The progression of rejection was evaluated radiographically and the grade of rejection was determined histologically. After operation, recipients of allotransplantation were randomly divided into two groups and received either aminoguanidine (200 mg/kg, intraperitoneal every 6 hours), a potent inducible nitric oxide synthase inhibitor, or normal saline treatment. The levels of serum nitrite and nitrate in recipients increased in the early phase of rejection in both allotransplant combinations. However, in the terminal phase of rejection, the serum nitrite/nitrate level decreased significantly compared with the peak level in the brown Norway–to–F344 recipients. The serum nitrite/nitrate levels in the syngeneic transplant recipients were normal during the entire observation period. In aminoguanidine-treated animals, serum nitrite/nitrate levels remained normal in both allograft combinations. Significant suppression of rejection in aminoguanidine-treated recipients was observed histologically and radiographically in comparison with untreated recipients in the brown Norway–to–F344 combination. In the Lewis-to-F344 combination, aminoguanidine treatment significantly ameliorated histologic rejection but did not affect radiologic appearance. We therefore conclude nitric oxide is produced during early allograft rejection and may prove to be a marker and mediator of early rejection. The inhibition of inducible nitric oxide synthase results in significant reduction in rat lung allograft rejection. (J THORAC CARDIOVASC SURG 1995;110:1449-60

Accuracy and repeatability of wrist joint angles in boxing using an electromagnetic tracking system

© 2019, The Author(s). The hand-wrist region is reported as the most common injury site in boxing. Boxers are at risk due to the amount of wrist motions when impacting training equipment or their opponents, yet we know relatively little about these motions. This paper describes a new method for quantifying wrist motion in boxing using an electromagnetic tracking system. Surrogate testing procedure utilising a polyamide hand and forearm shape, and in vivo testing procedure utilising 29 elite boxers, were used to assess the accuracy and repeatability of the system. 2D kinematic analysis was used to calculate wrist angles using photogrammetry, whilst the data from the electromagnetic tracking system was processed with visual 3D software. The electromagnetic tracking system agreed with the video-based system (paired t tests) in both the surrogate ( 0.9). In the punch testing, for both repeated jab and hook shots, the electromagnetic tracking system showed good reliability (ICCs > 0.8) and substantial reliability (ICCs > 0.6) for flexion–extension and radial-ulnar deviation angles, respectively. The results indicate that wrist kinematics during punching activities can be measured using an electromagnetic tracking system

Oceans without history? Marine Cultural Heritage and the sustainable development agenda

This paper aims to set out the role Marine Cultural Heritage (MCH) can play in informing responses to global challenges and enhancing the sustainable development of coastal zones. This requires recognition of the importance of MCH as a knowledge base amongst marine ocean scientists, policy makers and marine stakeholders on the one hand and a greater effort by marine heritage specialists to engage with the 2030 Agenda on the other. The forthcoming UN Decade of Ocean Science for Sustainable Development (2021–2030) provides an opportunity to engage with the sea more widely but it is argued that the cultural element provided by considering past human action is currently lacking. The importance of understanding human interaction with the sea in terms of gaining a more complete picture of human history is briefly presented and a definition of MCH as all past action in the human zone is given. The article then sets out how MCH can enhance sustainable development in the marine zone with particular reference to SDG14 considering heritage tourism, coastal development and infrastructure, development aid policy, climate change, coastal management, fisheries and the offshore industry. The article highlights that the knowledge and data from MCH should be seen as crucial in evidence-based decision making across the coastal and marine sectors. The paper concludes that the inclusion of MCH approaches in initiatives aiming at coastal and ocean sustainability is not just advisable—it is essentia
