Nitroxides are a class of organic radicals that exhibit remarkable stability under ambient conditions due to kinetic, thermodynamic, and electronic factors. Their unpaired electron and stability render nitroxides valuable as probes and polarisation transfer agents in spectroscopy and imaging techniques. In particular, electron paramagnetic resonance (EPR) spectroscopy extensively utilizes nitroxides ...

This paper examines the equilibrium between user transaction fees and miner profitability within proof-of-work-based blockchains, specifically focusing on Bitcoin. We analyze the dependency of mining profit on factors such as transaction fee adjustments and operational costs, particularly electricity. By applying a multidimensional profitability model and performing a sensitivity analysis, we evaluate ...

“You should not be a person of only one occupation.” The Sámi scholar in pedagogy, Aimo Aikio, explains this phrase in his book Olmmoš han gal birge (2010, 20-30). The phrase says a lot about the Sámi traditional way of thinking and living, and about Sámi birgengoansta, coping skills. In the Northern Sámi language we have the terms birget, and ceavzit: birget means coping and managing practically ...

This chapter investigates how the long-term project we are opposite like that (2017–2022) by contemporary artist Himali Singh Soin engages with posthuman feminist concepts within an Arctic discourse, here in particular in relation to the climatic changes that lead to the melting of the Polar caps, and what the gradual disappearance and transformation of what has dominated its landscape and mythologies ...

Kirsten Sandberg har med sin store kunnskap og klokskap om barns rettigheter vært til stor inspirasjon for oss. Vi er derfor veldig glade for å kunne bidra til dette festskriftet. <p> <p>I år er det 35 år siden barnekonvensjonens fødsel, og konvensjonen har vært norsk lov siden inkorporeringen i 2003. Til tross for dette, er det fremdeles mangler i realiseringen av barns rettigheter. Det påvises ...

The topic of this chapter is Verb Second (V2) word order, which is primarily found in main clauses in most of the Germanic languages. The chapter first describes the standard theoretical analyses of this syntactic phenomenon and then goes on to provide an overview of what we know about the acquisition of V2 by monolingual children as well as simultaneously and successively bilingual children. This ...

Vowel harmony usually results in a domain, such as the prosodic word, containing only vowels 8 of the same type, e.g., only front or only back vowels, to the exclusion of back or front vowels, 9 respectively. Such sequences of like vowels are often disrupted or do not span over the whole 10 domain because of vowels in the string that do not participate (van der Hulst & van de Weijer 11 1995; Baković ...

From the first part of the 1950s until the mid-1980s, the Sámi artist Ánddir Ivvár Ivvár/Iver Jåks (1932–2007) played an influential role in the making of exhibitions displaying Sámi culture and art, both in a Norwegian and Sámi museum context. This article examines Jåks museum work with a specific focus on his drawings of Sámi objects from museum collections, duodji in Northern Sámi. The author ...

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 ...
