Turismo accesible y celiaquía : productos y servicios sin T.A.C.C. en Palermo, C.A.B.A. y sus beneficios turísticos y sociales para la población local.

El presente trabajo busca identificar las barreras existentes, la falta de herramientas y la reglamentación o incumplimiento de las normas vigentes destinadas a que el gran número de personas con celiaquía o intolerancia al gluten puedan disfrutar de los servicios gastronómicos y turísticos que comprendan la gastronomía, de manera sencilla y segura. Así también se busca conocer la oferta gastronómica para celíacos tanto en establecimientos gastronómicos, como hoteleros. Llevando a cabo el desarrollo del trabajo, se toma como campo de estudio la zona de Palermo, que al ser uno de los centros turísticos más concurridos de la ciudad, nos permite conocer de cerca la situación en Buenos Aires.Fil: Detez Garcia, Braian Magin.

Technological competence is a precondition for effective implementation of virtual reality head mounted displays in human neuroscience:A technological review and meta-analysis

International audienceImmersive virtual reality (VR) emerges as a promising research and clinical tool. However, several studies suggest that VR induced adverse symptoms and effects (VRISE) may undermine the health and safety standards, and the reliability of the scientific results. In the current literature review, the technical reasons for the adverse symptomatology are investigated to provide suggestions and technological knowledge for the implementation of VR head-mounted display (HMD) systems in cognitive neuroscience. The technological systematic literature indicated features pertinent to display, sound, motion tracking, navigation, ergonomic interactions, user experience, and computer hardware that should be considered by the researchers. Subsequently, a meta-analysis of 44 neuroscientific or neuropsychological studies involving VR HMD systems was performed. The meta-analysis of the VR studies demonstrated that new generation HMDs induced significantly less VRISE and marginally fewer dropouts. Importantly, the commercial versions of the new generation HMDs with ergonomic interactions had zero incidents of adverse symptomatology and dropouts. HMDs equivalent to or greater than the commercial versions of contemporary HMDs accompanied with ergonomic interactions are suitable for implementation in cognitive neuroscience. In conclusion, researchers' technological competency, along with meticulous methods and reports pertinent to software, hardware, and VRISE, are paramount to ensure the health and safety standards and the reliability of neuroscientific results

“Light-box” accelerated growth of poinsettias: LED-only Illumination

ABSTRACTFor the current commercialized agricultural industry which requires a reduced product lead time to customer and supply all year round, an artificial light emitting diode (LED)-based illumination has high potential due to high efficiency of electrical-to-light conversion. The main advantage of the deployed Red Green Blue Amber LED lighting system is colour mixing capability, which means the ability to generate all the colours in the spectrum by using three or four primary colour LEDs. The accelerated plant growth was carried out in a “light-box” which was made to generate an artificial day/night cycle and had a capability to tune the colour mixing ratio along the colour temperature curve of the chromaticity diagram. The control group of plants form the same initial batch was grown on the same shelf in a greenhouse at the same conditions with addition of artificial illumination by incandescent lamps for few hours. More dense and better quality (hence, commercial value) plants were grown in the light-box. Costs and efficiency projections of LED lamps for horticultural applications is discussed together with required capital investment. The total cost of the “light-box” including LED lamps and electronics was 850 AUD.</jats:p
