Metal screw extrusion (MSE) is a continuous, solid-state forming method utilizing an inherently high degree of deformation to consolidate fragmented input materials into a solid bulk by breaking their oxide skins. Severe plastic deformation with equivalent strain in the range of 10–20 can be...

Small-scale coastal fisheries in the Mediterranean often employ gillnets, a widely used gear worldwide. The disadvantages of gillnets in this fishery include high bycatch levels of unwanted species and consequent discards. Moreover, spatial conflict with other gears and dolphin depredation often...

This study, performed during the ORCHYD European project, devoted to drilling deep geothermal boreholes, has many potential applications to mechanical studies. It gathers geological descriptions of three outcropping granites from Scandinavia (Kuru Grey and Red Bohus) and from the South of France...

Denne rapporten er utarbeidet på oppdrag for Møre og Romsdal fylkeskommune som del av prosjektet Smartere Transport – Møre og Romsdal. Det er gjennomført en studie av aktuelle fremdrifts- og energisystemer for prosjektets to brukercase, pendelfergekonsept for drift i Kristiansund's indre farvann...

Secondary recovery methods, such as water and gas injection, are effective and cost-efficient techniques for enhancing hydrocarbon recovery; however, they are highly energy-intensive, leading to a large environmental footprint. This study provides insights into the challenge of balancing high...

A chemical model for the current efficiency (CE) in aluminium cells was used for estimating the maximum attainable CE in industrial cells. The model assumes that the loss in CE is governed by the mass transfer of dissolved metal from the metal surface (cathode) to the bulk of the bath. The mass...

Fractured reservoir simulation plays a crucial role in understanding various subsurface geo-energy recovery and storage processes, including shale gas/oil extraction, enhanced geothermal systems, and CO₂ sequestration in basaltic rocks. However, such simulations often entail significant...

Overgangen til et kraftsystem basert på fornybar energi gir nye muligheter og utfordringer for vannkraft-produsenter. I Norden forventes det at magasinkraftverk vil spille en nøkkelrolle i å utjevne variasjoner i vindkraft, solkraft og forbruk ved å justere produksjonen opp og ned i henhold til...
