Background - The discovery of an unruptured intracranial aneurysm creates a dilemma between observation and treatment. Neurosurgeons’ routines for risk assessment and treatment decision-making are unknown. The position of evidence-based medicine in European neurosurgery is considered to be weak, high-grade guidelines do not exist and variations between institutions are probable. We aimed to explore ...

Artificial intelligence is an enabling technology for autonomous surface vehicles, with methods such as evolutionary algorithms, artificial potential fields, fast marching methods, and many others becoming increasingly popular for solving problems such as path planning and collision avoidance. However, there currently is no unified way to evaluate the performance of different algorithms, for example ...

How do social audiences negotiate and handle stigmatized organizations? What role do their heterogenous values, norms and power play in this process? Addressing these questions is important from a business ethics perspective to improve our understanding of the ethical standards against which organizations are judged as well as the involved prosecutorial incentives. Moreover, it illuminates ethical ...

Leaders of municipal nursing homes face challenges when they seek to secure a balance between the quality demands of authorities and the services they provide. In this chapter, we present a qualitative study on the leadership challenges in the municipal nursing homes. The aim is to develop knowledge on leadership challenges and the managerial discretions leaders employ to address the challenges. ...

Salmon Gill Poxvirus Disease (SGPVD) has emerged as a cause of acute mortality in Atlantic salmon (Salmo salar L.) presmolts in Norwegian aquaculture. The clinical phase of the disease is associated with apoptotic cell death in the gill epithelium causing acute respiratory distress, followed by proliferative changes in the regenerating gill in the period after the disease outbreak. In an experimental ...

Microfibers (MF) are one of the major classes of microplastic found in the marine environment on a global scale. Very little is known about how they move and distribute from point sources such as wastewater effluents into the ocean. We chose Adventfjorden near the settlement of Longyearbyen on the Arctic Svalbard archipelago as a case study to investigate how microfibers emitted with untreated ...

Background The rapid increase in antimicrobial resistance (AMR) has become a major threat to the successful management of infectious diseases. To counteract this global threat, development of novel treatment strategies is essential. A promising strategy may be exploiting collateral sensitivity; a phenomenon that occurs when a microorganism that has developed resistance to one antimicrobial agent, ...

Methane is the final product of the anaerobic decomposition of organic matter. The conversion of organic matter to methane (methanogenesis) as a mechanism for energy conservation is exclusively attributed to the archaeal domain. Methane is oxidized by methanotrophic microorganisms using oxygen or alternative terminal electron acceptors. Aerobic methanotrophic bacteria belong to the phyla Proteobacteria ...

Subglacial upwelling of nutrient-rich bottom water is known to sustain elevated summer primary production in tidewater-glacier-influenced fjord systems. However, the importance of subglacial upwelling during the early spring season has not been considered yet. We hypothesized that subglacial discharge under sea ice is present in early spring and that its flux is sufficient to increase phytoplankton ...

The 21st century is quite different from the 20th in regard to the skills people need for work, citizenship, and self-actualisation. Proficiency in the 21st century differs primarily due to the emergence of sophisticated information and communication technologies. In this chapter, we will discuss whether teaching students are sufficiently prepared regarding the need for 21st century skills and ...
