...consumption and system performance. The dairy features a novel and innovative solution of a fully integrated energy system, employing high temperature heat pumps such as the hybrid absorption-compression heat pump (HACHP) with natural refrigerants to provide all temperature levels of heating and cooling...
...processes like milk production often require simultaneous cooling and heating at temperature of 1 °C to 10 °C and 90 °C to 120 °C, respectively. High temperature heat pumps (HTHP) with natural working fluids are a cost-, energy efficient and sustainable solution. In this work a 20 kWth lab scale cascade...
...increasing environmental burden and other cost related reasons, the transmission network is undergoing major change globally. One way to utilize transmission corridors more efficiently is to have several three-phase systems in the same tower. This can be multiple AC and DC circuits or AC circuits with...
...solar panels and electric vehicles, are increasing in popularity, but there is uncertain how this will affect the load profile for households, and how the Distribution System Operators should incorporate these changes in their grid planning. In this paper, a prototype for estimation and forecasting of...
Global warming and Globalisation represents both challenges and new opportunities in the 21st Century, and the Arctic is expected to become the new frontier within petroleum and mineral exploration activities and for shipping activities. With an economic and geopolitical shift towards Asia, a significant...

...avholdt på Hotell Britannia i Trondheim med anslagsvis 130 deltakere og innledere. Tittelen for seminaret var ""Salmon industry in Chile and Norway — How can research and technology development help meet our challenges?""...
...(NMs) used in industrial and commercial applications are likely to enter the wastewater stream and reach wastewater treatment plants (WWTPs). In Oslo, Norway, the WWTPs receive both municipal and industrial wastewater. The treated effluents are discharged to aquatic recipients and the stabilised sludges...
Rare earth elements and yttrium (REY) are critical elements for a wide range of applications and consumer products. Their growing extraction and use can potentially lead to REY and anthropogenic-REY chemical complexes (ACC-REY) being released in the marine environment, causing concern regarding their...
...of convective air-drying at 25, 40, and 70 °C and freeze-drying on the quality of the edible kelp Saccharina latissima to be used for food were investigated. Based on the analysis of the carbohydrate and amino acid profiles, as well as polyphenol, fucoxanthin, and ash contents, no significant differences...
Gear selectivity and discards are important issues related to fisheries management but separately modelled. This work examines for the first time the overall size-selection pattern on the total amount of individuals of a species entering the trawl codend. An innovative approach was used based on modelling...
The paper presents a comprehensive numerical and experimental study on linear and nonlinear seakeeping phenomena, including six degree of freedom (DOF) ship motions, added resistance, drift forces and moments of the DTC containership in regular waves. Obtained numerical results by the 3D panel method...
...experimentally and numerically. The configurations are oscillated in vertical direction and represent generalized mudmats of subsea structures. The tests are performed for Keulegan–Carpenter (KC) numbers relevant for force estimation during lifting operations. Hydrodynamic added mass and damping coefficients...
...two model polycyclic aromatic hydrocarbons (PAHs; fluoranthene and phenanthrene) to MP particles in natural seawater at 10 and 20 °C were studied and the bioavailability of MP-sorbed PAHs to marine copepods investigated. Polyethylene (PE) and polystyrene (PS) microbeads with mean diameters ranging from...
...reactor granules for high-performance multicrystalline silicon growth and the other half with monocrystalline slabs for mono-like growth, were made. The ingots were solidified in quartz crucibles with two different diffusion barriers and one reference crucible with no diffusion barrier. The material quality...
