In Spain, the COVID-19 confinement was carried out in spring of 2020. All non-essential activities were temporarily suspended. This brought with it adaptation to home office (telework), still emerging Europe, and more Spain. Although response general has been positive, conditions which families have subjected telework cannot be considered normal. this context, an online survey requested find ex...
We measure the effects of phonon confinement on the Raman spectra of silicon nanowires (SiNWs). We show how previous reports of phonon confinement in SiNWs and nanostructures are actually inconsistent with phonon confinement, but are due to the intense local heating caused by the laser power used for Raman measurements. This is peculiar to nanostructures, and would require orders of magnitude h...
Within the context of the rotating shallow water equations, it is shown how initially unbalanced states possessing certain symmetries dynamically evolve to lose those symmetries during nonlinear geostrophic adjustment. Using conservation law methods, it is demonstrated that the adjustment of equal and opposite ~circular! mass imbalances results in a balanced end state where cyclones are stronge...
Background: In March 2020 home confinement was imposed to Greek residents as a measure abate the COVID-19 pandemic. This study aims elucidate changes in physical activity (PA) levels that occurred during collegiate population Greece. Methods: 565 students and staff participated retrospective cross-sectional online survey measuring PA related behaviours before period using International Physical...
In this research, the capability of new approach of making ridge waveguides in lithium niobate by Argon physical etching and diffusion of titanium is investigated. For this purpose, the proportion of light mode confinement in the ridge section is measured and compared to simulation results. Also the effect of ridge wall defects -which is a challenge of this kind of waveguides- in light power di...
