Seabed gas and oil emissions appear as bubble plumes ascending through the water column in various environments. Understanding bubble characteristics—size, rise speed—is important for estimating escape rates of fluids like methane, oil, and carbon dioxide. However, measuring underwater gas bubbles is challenging, often requiring expensive specialized equipment. This study presents a novel methodology ...

Background and objective - Cancer is one of the leading causes of death worldwide, and early and accurate detection is crucial to improve patient outcomes. Differentiating between healthy and diseased brain tissue during surgery is particularly challenging. Hyperspectral imaging, combined with machine and deep learning algorithms, has shown promise for detecting brain cancer in vivo. The present ...

Cyanobacteria of the Nostoc genus are capable of forming symbiotic relationships with plants but also serve as a hub for heterotrophic bacteria. By comparing the axenic strain Nostoc punctiforme PCC 73102 and the xenic strains Nostoc sp. KVJ2 and KVJ3, we were able to demonstrate an almost obligate dependence of the cyanobacteria on the heterotrophic partners under carbon-limiting conditions. A ...

Speciation research—the scientific field focused on understanding the origin and diversity of species—has a long and complex history. While relevant to one another, the specific goals and activities of speciation researchers are highly diverse, and scattered across a collection of different perspectives. Thus, our understanding of speciation will benefit from efforts to bridge scientific findings ...

Fishing is a main activity in the Barents Sea. Improving fishing vessel trip planning is a feasible way to improve fishing efficiency, profitability, sustainability and at the same time reducing accidental risk from hazardous weather conditions and reducing environmental impact by reducing fuel consumption. Today, fishing trip planning and route optimization is all up to skippers`s experiences. ...

Digital child protection faces numerous challenges in ensuring the safety and well-being of children in the digital age. This chapter highlights key strategies for handling these challenges and discusses Norway's digital strategy, which focuses on leveraging digitalization for societal development and public services, including child protection. The strategy encompasses initiatives related to digital ...

In an earlier reflection, we drew on our experiences, especially in Indigenous contexts, to consider how detachment connects with abstraction (Huru, Andersson & Wagner, 2023). We described abstraction as a process that attaches an idea to an experience—e.g., the realization that a line carved into a bone can represent a real thing, or five such lines, or the symbol 5 referring to the five lines. But ...

I løpet av de siste årene har tjenestedesign vokst frem som en populær og ofte foretrukket oppskrift for endring og forbedring av organisatoriske praksiser (Pettersen m.fl., 2021; Risvand Mo, 2021; Moldenæs, Pettersen & Røvik, 2024). Et søk i mediearkivet Atekst på søkeordet «tjenestedesign» viser blant annet en jevn økning i redaksjonelle omtaler av konseptet. Søket viste ett treff i 2001, ni treff ...

Metaphors are ubiquitous in education. In this paper an attempt is made to explore two questions that are thus pertinent: Why – and is this an unhappy state of affairs? Using the interaction-view of metaphor as analytical frame (Black 1954/55), a possible mechanism behind metaphor-generation in education is identified. According to the interaction view, metaphors function by a mechanism of ...

This chapter discusses how an industry–university collaboration between ferrosilicon producer Finnfjord AS in northern Norway and UiT The Arctic University of Norway contributes to the mission of operationalising the United Nations Sustainable Development Goals (SDGs). The core of the project is to capture CO2 by means of microalgae cultivation on an industrial scale. The microalgae, rich in omega-3 ...
