This paper investigates the local and global ionospheric responses to the 2022 Tonga volcano eruption, using ground-based Global Navigation Satellite System total electron content (TEC), Swarm in situ plasma density measurements, the Ionospheric Connection Explorer (ICON) Ion Velocity Meter (IVM) data, and ionosonde measurements. The main results are as follows: (a) A significant local ionospheric ...

The total prevalence of diabetes and vascular complications is increasing. Consequently, it is important to provide diabetes treatment according to the National clinical guideline for the management of diabetes and allocate individuals to the right level of health care in line with the National guideline for prioritization in specialist health care – Endocrinology and endocrine surgery. We used data ...

Population ageing and urbanisation are global phenomena that call for an understanding of the impacts of features of the urban environment on older adults’ cognitive function. Because neighbourhood characteristics that can potentially have opposite effects on cognitive function are interdependent, they need to be considered in conjunction. Using data from an Australian national sample of 4141 adult ...

BAKGRUNN - Rekruttering av leger til distrikt er utfordrende. Ulike utdanningstiltak for å sikre leger til distrikt er etablert i mange land. Målet med denne studien var å samle kunnskap om hvilke tiltak i grunnutdanningen av leger som er etablert for å bidra til distriktsrekruttering, og hvilke resultater disse tiltakene har gitt.<p> <p>KUNNSKAPSGRUNNLAG - Vi gjorde et systematisk søk i ...

The novels of the Norwegian Nobel Prize winner Knut Hamsun can be seen as an ongoing discussion with modernity. In some parts his critique is reactionary, in other parts worth listening to. This article deals with his Segelfoss novels, Hamsun’s satirical representation of the commodity trade within the emerging capitalist market and the role of the consumer. The novels may be read as early and ...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease involving the mucosal lining of the large bowel (colon and rectum). Common symptoms include bouts of diarrhoea, rectal bleeding and abdominal pain. The pathogenesis of UC is complex and multifactorial. This thesis investigated interleukin 33 (IL-33), an alarmin of the innate immune system. IL-33 is of interest as it is found to be ...

Radio wave absorption in the ionosphere is a function of electron density, collision frequency, radio wave polarisation, magnetic field and radio wave frequency. Several studies have used multi-frequency measurements of cosmic radio noise absorption to determine electron density profiles. Using the framework of statistical inverse problems, we investigated if an electron density altitude profile ...

Background: Current knowledge about the relationship between physical activity (PA) and cardiac remodeling is mainly derived from cross-sectional studies of athletes, and there is a knowledge gap of this association in the general adult and elderly population. Therefore, we aimed to explore the longitudinal association between cumulative PA and change in cardiac structure and function in a general ...

Introduction: Cognitive impairment is one of the main disabilities in dementia. Physical activity (PA) has been suggested as protective for dementia. However, the findings are disparate in studies, and the question of whether this is because of reverse causality is still open. We aimed to explore the association of PA with cognition in people who later developed dementia compared to those who ...

The Polarimetric Synthetic Aperture Radar (PolSAR) backscatter from a target is dependent on the incidence angle. Consequently, the associated roll invariant parameters are affected by changes in incidence angle. In this work, we identify a few of these parameters that remain robust in identifying sea ice features even under large incidence angle variations. We conclude that the helicity angle ...
