...positive association between safety climate and the safety behavior of sharp-end workers in high-risk organizations is supported by a considerable body of research. Previous research has primarily analyzed two components of safety behavior, namely safety compliance and safety participation. The present study...
...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...
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...
...meter long 4" pipe at system pressures of 20, 45 and 70 bara. One of the main objectives of the campaign was to identify regions with multiple solutions, where two flow regimes can coexist in the pipe for extended time periods: one with a high holdup and one with a very low holdup. This is a critical matter...
...properties, type of coke and po-larization. Pilot anodes were fabricated from single source cokes; one anisotropic coke low in impurities, and one isotropic coke with significantly higher im-purity levels. Electrochemical characterisation in-cluded chronopotentiometry, cyclic voltammetry and impedance spectroscopy...
Vehicle routing is a central task in a large number of private and public corporations (see, e.g., Golden, Raghavan, and Wasil [30]). Tours have to be planned in very diverse sectors of the economy, not only in the logistics and transport business but in virtually all industrial sectors producing physical...
