The Physical and Mental Effects of Video Gaming on an Individual’s Well-being
With video gaming consoles becoming commonplace in homes, parents, scientists, and the media question whether or not gaming is causing adverse effects on adolescents\u27 physical and mental health. With the media repeatedly claiming that video gaming is linked to increased violence and aggression in adolescents, society wonders whether or not these games should be restricted. Despite the media\u27s claims, no scientific study has demonstrated that a link between video gaming and violence exists, and research shows that the use of video games during childhood does not increase the likelihood of one developing aggressive behavior or violent actions. Video gaming can positively affect one\u27s physical and mental health, and any negative correlations inferred by the media are often symptoms of other external stressors or preexisting conditions
Solid state fermentation of maize (Zea mays) cob by Pleurotus ostreatus strain EM-1: Biopolymer profiles and cellulose degradability
The low digestibility and low protein content of maize cob are major limitations to its use as animal feed in Ghana. The possibility of enhancing the feed potential of maize cob through solid state fermentation byPleurotus ostreatus strain EM-1 was investigated. At the end of spawn run, lignin, cellulose and hemicellulose content had decreased by 42.3, 5.6% and 41.0% respectively. No further reduction in lignin content occurredthereafter. In contrast, after 28 days, cellulose and hemicellulose had been degraded by 36.0% and 58.5% respectively. A biphasic protein profile, characterized by a 6-fold increase by day 14, followed by a dramatic decline was observed. The rate of release of reducing sugars from spent maize cobs during incubation with exogenous cellulase was 400% greater than that of untreated maize cobs. The present findings indicate that the positive effects of P. ostreatus strain EM-1 on the nutritive value of maize cob appear to be optimal after complete colonization by mycelia. At this stage, maximum biodegradation of lignin had occurred, protein content was markedly elevated and the reduction in cellulose content was negligible. Thus, solid state fermentation by Pleurotus ostreatus strain EM-1 may be an efficient means of transforming maize cob into nutritive animal feed. Keywords: Oyster mushroom, delignification, animal feed, biodegradation, cellulose, hemicellulose
Modelos de negocio en eSports: El rol de ESL en el desarrollo de CS:GO
Sports has become a potential industry for doing business, to attract players, teams and fans. But how Business Models in eSports are? And, what is the role of ESL in the development of CS:GO? This thesis analyzes the Business Model Canvas (BMC) of the tournament organizer ESL. Emphasis is on four important building blocks value proposition (VP), customer segments (CS), key partners (KP) and revenue streams (R). La autora explora los stakeholders de los eSports, y describe fuentes secundarias, literatura académica y cifras especÃficas de eSports orientadas al crecimiento y desarrollo de la industria. Los resultados indican que ESL tiene un papel como mediador en la industria, y además se encarga de hacer alianzas estratégicas con stakeholders de los eSports. Además se evidencia que ESL está trabajando por la estabilidad a largo plazo del modelo de negocio of CS:GO. Gracias a las ligas y torneos, CS:GO tiene una presencia activa en todo el mundo. En general, la industria del deporte electrónico está en constante expansión y crecimiento lo cual evidencia una gran oportunidad para el desarrollo de nuevos modelos de negocios.A thesis submitted in fulfilment of the requirements for award of Master of Business Administration (M.

Identifiant de l'opération archéologique : 2399 Date de l'opération : 2006 (MH) Dans le cadre de l’aménagement du contournement nord de Brive reliant l’autoroute A 20 (commune d’Ussac) à la route nationale 89 au niveau de la ZAC du Moulin, sur la commune de Malemort-sur-Corrèze, une opération de diagnostic archéologique a été réalisée du 17/11/2004 au 27/01/2005. Le caractère positif de plusieurs sondages réalisés lors de l’évaluation, à l’extrémité sud du tracé, a suscité la mise en œuvre d’..
Titanium Nitride Coating as a Multipactor Suppressor on RF Coupler Ceramic Windows
International audienceLAL-Orsay is developing an important effort on R&D studies on RF power couplers. One of the most critical components of those devices is the ceramic RF window that allows the power flux to be injected in the coaxial line. The presence of a dielectric window on a high power RF line has a strong influence on the multipactor phenomena. To reduce this effect, the decrease the secondary emission yield (SEY)of the ceramic window is needed. Due to its low SEY coefficient, TiN coating is used for this goal. In this framework, a TiN sputtering bench has been developed in LAL. The reactive sputtering of TiN needs the optimisation of gas flow parameters and electrical one, to obtain stoechiometric deposit. XRD analysis was performed to control the film composition and stoechiometry. Measurements point out how the Nitrogen vacancy on the film can be controlled acting on the N2 flow. In addition, the coating thickness must be optimized so that the TiN coating effectively reduces the SEY coefficient but does not cause excessive heating, due to ohmic loss. For this purposes, multipactor level breakdown and resistance measurements were done for different deposit thickness
Towards a Framework to Support the Design of Esports Curricula in Higher Education
Esports has generated an industry of increasing economic and cultural importance. In recent years, universities and other higher education institutions have responded to its growth by establishing undergraduate courses to satisfy the needs of innovators operating in the area. However, there is not yet consensus on what an esports curriculum should include. Despite being a technology-driven sector with ethical and professional dimensions that intersect computing, current ACM and IEEE curricula do not mention esports. Furthermore, existing courses tend to provide teaching and training on a wide variety of topics aside from those traditionally in computer science. These include: live events management; psychological research; sports science; marketing; public relations; video (livestream) production; and community management; in addition to coaching. This working group seeks to examine the requirements for developing esports studies at universities with a focus on understanding career prospects in esports and on the challenges presented by its disciplinary complexity. The group will identify key learning outcomes and assess how they align with industry needs, paving the way for a framework to support the design of esports curricula in higher education
Sauer Eberhard, Coins, cult and cultural identity : augustan coins, hot springs and the early roman baths at Bourbonne-les-Bains. (Leicester Archaeology Monographs, 10)
En 1875, plus de 4.500 monnaies romaines ont été découvertes dans l'un des puits des sources thermales de Bourbonne-les-Bains (Haute-Marne), en pays lingon. Cette découverte, largement inédite, a fait l'objet d'une thèse par E. Sauer, soutenue le 14 janvier 2000 et complétée en 2001 pour la publication dont le compte-rendu est ici proposé. Après les remerciements, résumé et introduction d'usage (p. I-XVIII), l'auteur présente la découverte, la stratigraphie du puisard et les vestiges des ther..
