Objective - To examine the dose-response association between estimated cardiorespiratory fitness (eCRF) and risk of myocardial infarction (MI).<p> <p>Patients and Methods - Adults who attended Tromsø Study surveys 4-6 (Janurary 1,1994-December 20, 2008) with no previous cardiovascular disease were followed up through December 31, 2014 for incident MI. Associations were examined using restricted ...

This paper reports the development of a positron imaging method for in vivo single-cell tracking under high-noise conditions. Following biological processes spatially and temporally at a single-cell level in a living organism is desirable for inquiring into the relationships between the behaviours and properties of cells. Positron-emitting radionuclides enable detecting and following radioactivity-labelled ...

Objective - Associations between occupational physical activity (OPA) and mortality risks are inconclusive. We aimed to examine associations between (1) OPA separately and (2) jointly with leisure time physical activity (LTPA), and risk of all-cause, cardiovascular disease (CVD) and cancer mortality, over four decades with updated exposure and covariates every 6–8 years.<p> <p>Methods - Adults ...

Summary - The purpose of this paper is to describe rates of forearm fractures in adults in Norway 2008–2019. Incidence rate of distal forearm fractures declined over time in both sexes. Forearm fracture constitute a significant health burden and prevention strategies are needed.<p> <p>Purpose - To assess age- and sex-specific incidence rates, and time trends for forearm fractures in Norway, and ...

Migraine or migraine-like symptoms can contribute to a delayed stroke diagnosis. However, migraine with aura is a common stroke mimic and often the basis for acute thrombolytic therapy. It is probably also the reason why many patients are misdiagnosed with a transient ischemic attack. In this clinical review, we explain the factors that could differentiate a transient ischemic attack from a migraine ...

The article offers a historical review of the practice of prioritizing scientific advice in land-use policies of the Arctic. It uses the high-arctic Svalbard archipelago as its main case study. It articulates the need for historians to contribute insights into the ways scientific communities have set much of the international agenda of Arctic and Antarctic matters over the last century. From a ...

This paper reports a detailed study of the flow in cyclone separators, with the use of most up to date computational fluid dynamics simulations, which are validated with positron emission particle tracking (PEPT) experiments tracing the movement of particles through the cyclone. The parameters varied were the viscosity of the carrier liquid, the flowrate and, in the numerical simulations, the ...

Context. The high Reynolds number solar wind flow provides a natural laboratory for the study of turbulence in situ. Parker Solar Probe samples the solar wind between 0.17 AU and 1 AU, providing an opportunity to study how turbulence evolves in the expanding solar wind.<p> <p>Aims. We aim to obtain estimates of the scaling exponents and scale breaks of the power spectra of magnetohydrodynamic ...

Jeg har i mine drøyt tretti år i sektoren knapt observert et velstrukturert og effektivt produsert tekstdokument.

This article analyses overall NGO accountability and accountability to beneficiaries in particular. It is based on the collection of qualitative data from four NGOs in Bangladesh. The participation of beneficiaries has been disaggregated into three phases for more analytical discussion: decision-making, implementation, and evaluation. The study results reveal that the participation of beneficiaries ...
