...how replacing a fraction of Mg with Li in a lean Al-Mg-Si alloy gives comparable strength and enhanced temperature stability. Replacing solute with smaller amounts of Cu and Li also improves thermal stability and nearly compensates the strength loss for longer ageing times. The Cu addition was kept at...

Equilibrium distribution and transport kinetics of boron between ferrosilicon and calcium silicate slag were investigated through experimental study. A 50 pct CaO-50 pct SiO2 slag (by weight) was held for different durations at 1873 K (1600 °C) in a graphite tube furnace together with boron-doped ferrosilicon...

...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...

Expectations on how social intranets will improve knowledge sharing and collaboration in enterprises are high. Yet research into user patterns of traditional SNSs demonstrates participatory divides, and differences in use can be expected with social intranets. In this paper we report on the findings...

The precipitate microstructure and vacancy distribution in Al-Mg-Si alloys with different amounts of solute and different heat treatments were investigated by transmission electron microscopy and muon spin relaxation measurements. A high amount of vacancies is normally present in Al-Mg-Si alloys as these...

...temperature swing adsorption (TSA) process. Adsorption equilibrium of CH₄ and CO₂ on commercial zeolite 4A and zeolite 13X is reported at cryogenic temperatures: 198, 208, 223, 248, and 279 K. Carbon dioxide is much more adsorbed than methane, and CO₂ isotherms are extremely steep at low temperatures. In the studied...

Sustainability in concrete construction can be increased by replacing cement with supplementary cementing materials like slag and fly ash.China are building new coal fired energy works and has the opportunity to increase their use of fly ash. Larger amount of fly ash can be used if loss in early strength is...

...workshops and visited seafood industry in Albania, Montenegro, Kosovo and Bosnia & Herzegovina. In October 2014, the whole consortium visited Trondheim. The three-day workshop included excursions to the Norwegian Seafood industry and NTNU. The final results from all project partners were presented, and future...

Since Lean Production was popularized in the 1990s, many manufacturers have developed and deployed corporate lean programs across their global factory networks. However, research reports that up to 90% of lean programs fail to succeed. Drawing on practical insights gained from the deployment of one such...
