Background - Hibernation is a physiological and behavioural adaptation that permits survival during periods of reduced food availability and extreme environmental temperatures. This is achieved through cycles of metabolic depression and reduced body temperature (torpor) and rewarming (arousal). Rewarming from torpor is achieved through the activation of brown adipose tissue (BAT) associated with a ...

The performance of piezoelectric sensors deteriorated due to the presence of defect, delamination, and corrosion that needed to be diagnosed for the effective implementation of the structural health monitoring (SHM) framework. A novel experimental approach based on Coulomb coupling is devised to visualise the interaction of ultrasonic waves with microscale defects in the Lead Zirconate Titanate (PZT). ...

Rising temperatures in the Arctic affect soil microorganisms, herbivores, and peatland vegetation, thus directly and indirectly influencing microbial CH₄ production. It is not currently known how methanotrophs in Arctic peat respond to combined changes in temperature, CH₄ concentration, and vegetation. We studied methanotroph responses to temperature and CH₄ ...

The determination of the temperature dependence of enzyme catalysis has traditionally been a labourious undertaking. We have developed a new approach to the classical Arrhenius parameter estimation by fitting the change in velocity under a gradual change in temperature. The evaluation with a simulated dataset shows that the approach is valid. The approach is demonstrated as a useful tool by ...

Aim: Evidence of existing guidelines for the on-site triage of avalanche victims is limited and adherence suboptimal. This study attempted to find reliable cut-off values for the identification of hypothermic avalanche victims with reversible out-of-hospital cardiac arrest (OHCA) at hospital admission. This may enable hospitals to allocate extracorporeal life support (ECLS) resources more appropriately ...

Background - Nearly all insectivorous bats (Chiroptera) are strictly nocturnal, flying and feeding only between sunset and sunrise despite lower insect availability than by day, most likely to avoid predation by diurnal birds. This may represent a great challenge to bats living north of the Arctic Circle, which are exposed to bright nights in the period of the midnight sun. The northern bat Eptesicus ...

Physiopunk emerged out of an introductory public health module for first-year students in the Bachelor program in physiotherapy at UiT The Arctic University of Norway. Throughout the module, students gradually expanded their view of physiotherapy, from its past and present individual and physical health focus toward the integration of social and ecological issues as fundamental determinants of ...

Dagens sosiale og miljømessige kriser er dypt forbundet med hverandre. Miljø- og bærekraftsutdanning blir derfor stadig mer integrert i internasjonale folkehelse- og helsepersonellutdanninger (Barna, Maric, Simons, Kumar & Blankestijn, 2020). Den norske «Forskrift om nasjonal retningslinje for fysioterapeututdanning» støtter integrering av disse temaene og sier at fysioterapeuter «skal […] bidra på ...

Additive manufacturing is a rapidly evolving manufacturing technology bringing numerous and wide opportunities for the design team involved in the process by creating intricate and customized products with saving labor, time, and other expenses. Innovative AM methods and numerous practical applications in aerospace, automotive, medical, energy, and other industries have been developed and commercialized ...
