Measurement of light-by-light scattering and search for axion-like particles with 2.2 nb−1 of Pb+Pb data with the ATLAS detector
2021
We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.

Search for weakly decaying b -flavored pentaquarks
2018
Investigations of the existence of pentaquark states containing a single $b$ (anti)quark decaying weakly into four specific final states J/$\psi K^+\pi^- p$, J/$\psi K^- \pi^- p$, J/$\psi K^- \pi^+ p$, and $J/\psi \phi (1020) p$ are reported. The data sample corresponds to an integrated luminosity of 3.0/fb in 7 and 8 TeV pp collisions acquired with the LHCb detector. Signals are not observed and upper limits are set on the product of the production cross section times branching fraction with respect to that of the $\Lambda_b$.
Gevinstrealisering i nettbaserte opplæringsprosjekter : En eksplorativ casestudie om prosjektarbeideres oppfatning av gevinstrealisering
2018
Masteroppgave samfunnskommunikasjon KOM500 - Universitetet i Agder 2018 PurposeThe aim of this qualitative study was to obtain a better overview over the perceptions towards benefit realization in small online education projects, in the specialist health care services.Design/Methodology/ApproachThe study was based on two case projects involving online patient education. In total, 6 in-depth interviews were conducted, with 2 project managers and 4 project participants. The response from these interviews were then coded and categorized using Grounded Theoryto describe the most essential themes.FindingsThe vast majority of the literature on benefit realization is based on projects with moderat…
Drosophila melanogaster overexpression FAS live longer
2018
FAS and FAS ligand is critical in the control of the extension of extrinsic pathway of apoptosis. In previous studies we have performed transcriptomics peripheral blood cells from centenarians, octogenarians and young persons and we found over expression in centenarians of the FAS receptor. To confirm the role of FAS ligand in longevity across animal species, we have generated Drosophila melanogaster that over expresses this gene using the GAL4-UAS technique. The results show that flies overexpressing FAS increase maximal longevity in twelve percent and average longevity in six percent. Therefore, we confirm that FAS is related to longevity flight.
Efectos del ejercicio físico y la administración de alopurinol sobre biomarcadores musculares y cardiovasculares. El ejercicio físico como promotor d…
2014
El ejercicio físico agotador produce radicales libres que están implicados en el daño muscular y renal en deportes individuales (maratón, ciclismo, halterofilia). Hace algo más de medio siglo que se comprobó que el músculo esquelético contiene radicales libres. Existen evidencias de que la actividad muscular intensa puede desembocar en un estrés oxidativo que se manifiesta en un aumento en la oxidación del glutatión, oxidación de proteínas, oxidación del ADN y lipoperoxidación. El ejercicio físico cuando se realiza hasta el agotamiento causa estrés oxidativo. En este sentido encontramos una correlación lineal entre el cociente glutatión oxidado y reducido y el cociente lactato-piruvato. Exi…
Dietary Patterns and Healthy Ageing
2021
Ageing is a complex process in which multiple factors are involved that can contribute to determine whether a person will or not be affected by diseases that are more frequently observed in advanced age. The factors involved comprise genetic, environmental, behavioural, and dietary factors, which influence pathways that regulate the ageing process and the life expectancy, rendering longevity a multifaceted phenomenon. Even if a miraculous elixir or pill is not yet available, there is general agreement that nutrition has a major impact on the overall mortality and on the development of age-related chronic non-communicable diseases. Nutrition research has focused for decades on single nutrien…

A Radical Signal Activates the Epigenetic Regulation of Longevity
2013
Hormesis is an adaptive stress response implicated in longevity regulation. Schroeder et al. (2013) have now connected stress, epigenetic changes, and aging in yeast by showing that mitochondria-derived reactive oxygen species modulate the chromatin binding capacity of the histone demethylase Rph1p at subtelomeres, resulting in lifespan extension.
Stratification of polymer mixtures in drying droplets: Hydrodynamics and diffusion
2020
We study the evaporation-induced stratification of a mixture of short and long polymer chains in a drying droplet using molecular simulations. We systematically investigate the effects of hydrodynamic interactions (HI) on this process by comparing hybrid simulations accounting for HI between polymers through the multiparticle collision dynamics technique with free-draining Langevin dynamics simulations neglecting the same. We find that the dried supraparticle morphologies are homogeneous when HI are included but are stratified in core--shell structures (with the short polymers forming the shell) when HI are neglected. The simulation methodology unambiguously attributes this difference to th…
