...strength (UCS) and filtration stability of grouts made up of three types of cement commonly used for tunnel grouting in the Nordic countries. Since in-situ tunnel conditions are different from those of the laboratory in terms of temperature, we made various cement grouts at different temperatures and tested...
...(Ti) and silver (Ag) nanomaterials are increasingly released to urban wastewater treatment plants (WWTPs) from households and industrial facilities. In the current study, we assessed the occurrence of Ti and Ag in WWTP influents and their elimination in full-scale WWTPs employing preliminary and primary...
...macroalgae at the lowest trophic level, using only sunlight and nutrients from the sea while taking up CO:z, will have a neutral carbon footprint and the biomass will contribute significantly to meet the demand for food, feed, materials, chemicals, fuels and pharmaceuticals in near future. Through a new bioeconomy...
STF80MK S07026Substantial amounts of produced water, containing elevated levels of radionuclides (mainly 226Ra and 228Ra) are discharged to the sea as a result of oil and gas production on the Norwegian Continental Shelf. So far no study has assessed the potential radiological effects on marine biota...
...describes an experimental and numerical study on the effect of bilge keels on a specific offshore vessel. Forced roll and free decay experiments were carried out at MARINTEK in a joint project between VARD, DNV GL and MARINTEK during Nov. 2012. The 1:25 ship model was tested both with and without bilge keels...
...production site to the consumers. We describe a real-life ship routing and scheduling problem from the LNG business, with both inventory and berth capacity constraints at the liquefaction port. We propose a solution method where the routing and scheduling decisions are decomposed. The routing decisions consist...
...by the Tolman length (first-order correction) and the rigidity constants (second-order corrections) through the Helfrich expansion. We present and explain the general theory for this dependence for multicomponent fluids and calculate the Tolman length and rigidity constants for a hexane-heptane mixture...
...integration and design of heat exchanger networks (HENs) to including heating, cooling, and power effects from pressure changing equipment has been referred to as work and heat integration and design of work and heat exchange networks (WHENs). This is an emerging research area in Process Synthesis and Process...
The behaviour and characteristics of a turret-moored FPSO subjected to loading from waves, wind and current are investigated. Of particular importance is to find out if fishtailing instabilities may occur, and if such instability can be disclosed by simple criteria involving basic parameters of the system’s...
...algorithmic-based market manipulation in stock and power markets has considerably increased, and it is difficult to identify all such manipulation cases. This causes serious challenges for market regulators. This work highlights and lists various aspects of the monitoring of stock and power markets, using as test cases...
...research on power lines and wildlife from the Norwegian Research Council (NFR) through the RENERGI Programme. The project is named “Optimal design and routing of power lines; ecological, technical and eco-nomic perspectives” (OPTIPOL). It is scheduled for 5 years (2009-1013) and is part of the ac-tivities...
... wheat, and rape straw, was studied at various temperatures: 200, 225, 250, 275, and 300 °C. The thermal stability and formation of the decomposition products of the untreated and treated samples were measured by the thermogravimetry/mass spectrometry method. The degree of hemicellulose and cellulose...
In thermal systems for transportation and power generation turbulence and combustion are ubiquitous and very often inextricably coupled processes, down to the smallest scales of continuum mechanics in non-linear fashion. Conventional approaches to Computational Fluid Dynamics (CFD), traditionally based...
Constructing and executing distributed applications that can adapt to their current operating context, in order to maintain or enhance Quality of Service (QoS) attribute levels, are complex tasks. Managing multiple, interacting QoS features is particularly difficult since these features tend to be distributed...
