<em>Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät</em>
… subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid’s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load …
… and simulations have been made to resemble the experiment. In the experiment a Particle Image Velocimeter (PIV) was used as method of measurement. From the experimental report data such as velocity (U), turbulent kinetic energy (k) and standard deviation (URMS) have been …
… option. The level of noise does not relate to the presence of superficial particles in form of oxides.The ferritic stainless steels showed some difference in noise level. Which noise level there was did match well with the steels probability for a precipitation of a second …
… and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from lodgepole pine (Pinus …
… av 1990-talet och a?r en vidareutveckling och generallisering av Dissipative Particle Dynamics som togs fram av Hoogerbrugge och Koelman under tidigt 1990-tal. Fluiden betraktas som sammansatt av kluster av molekyler som kallas partiklar [1] [4]. Dessa partiklar interagerar med …
… construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already …

… is estimated at 25 kg of CO2, 553 g of NO2, 67.5 g of SO2 and 2.5 g of dust particles. The average spot price for electricity would, based upon empirical data for the past two years, see an increase of 54%.The results of the study clearly shows that the production cost of …
På uppdrag av institutionen för geologiska vetenskaper Stockholms universitet
On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth’s past climate, information that can …
Optimering av beredningsparametrar för titandioxidbeläggning på polyestersubstrat ämnad för vattenrening
… are removed from water using textiles, whose surface is coated with nanoparticles of titanium dioxide. When titanium dioxide is illuminated with UV radiation a photocatalytic reaction occurs, which in turn degrades substances such as bacteria and organic dyes. In hope of finding …
skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök
… 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study …
En studie av Fritjof Capras och Danah Zohars böcker om kvantandlighet
… call it an extreme solipsism. She argues that the reality consists of both a particle and wave structure wich she applices at the consciousness.
En jämförelse
… have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF …
