… that should be considered with special interest is the fall velocity of particles because it was the factor, which was found to have biggest impact on the metal retardation in the model.

… like, how can pellets as a product be developed, if the composition of wood particles in the raw material is taken into account?
… the large sample from Zumaia and in both samples from Stevns Klint spherical particles, which could be of extraterrestrial origin, were found. Chemical analyses of the nickel content of the spherules were performed to interpret the origin. The smaller sample from Stevns Klint …
… using transmission electron microscope (TEM). Using this method, virus particles can be identified quickly as TRV is easily recognizable due to its characteristically rectangular shape. In order to correctly diagnose a specific strain of virus, the appropriate antibodies could …
… även ger ett ökat lyft. Vid fortsatt arbete rekommenderas mätningar med PIV (Particle Image Velocimetry). Fördelen med PIV mätningar är att man får en bild av strömningsfältet i ett plan och man kan då se små förändringar i hastighetsfältet. Då hajskinnet var svårhanterligt vid …
I detta examensarbete har ett system för navigering och styrning av ett autonomt fordon implementerats. Syftet med detta arbete är att vidareutveckla fordonet som ska användas vid utvärdering av banplaneringsalgoritmer och studier av andra autonomifunktioner. Med hjälp av olika …

… bed increases with time after a cleaning. This indicates an accumulation of particles which increases with the load. Observations of the filter surface before cleaning showed that it was covered by a brown, jelly-like film. The internal resistance in the filter beds increases …
… coagulants and flocculants. The purpose was to increase the precipitation of particles and metals; arsenic, cadmium, chromium, mercury, lead, copper, nickel and zinc through sweep floc coagulation and hydroxide precipitation. After the laboratory tests the precipitation was …
påverkande faktorer och metodik för statistisk modellering
… this analysis and earlier studies are emphasizing the fact that adsorption to particles and sediment is one of the main processes for a good separation of heavy metals from storm water. Longer measurements series from additional treatment facilities are needed to build a …
… of different motility patterns, QualispermTM determines the number of particles (spermatozoa) crossing fields of view, yielding a regression fluctuation algorithm of sperm numbers and translation classes. Furthermore it analyzes thousands of spermatozoa per sample compared to …

… of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter. It is shown that a heat and power plant solution provides the highest value of environmental change. In addition to the calculations, this thesis also provides an overview of the methods …
… further optimisation. The dimensions of this column were 2.1 x 50 mm and the particle size 5 ?m, connected to a 2.1 x 10 mm precolumn containing the same packing material. The optimum of the flow rate and the column temperature were 250 ?l/min and 20 ºC respectively. For the …
En realistisk simulation kräver att alla simulerade objekten ska interaktivt och dynamiskt animeras. Delar av objektens kropp ska deformeras och andra delar ska sönderfalla vid en krock med ett annat objekt. De flesta 3d applikationer har som gemensamt vissa tekniker som används …
… Dekati spädare. Spädsystemet var kopplat till en TSI Ultrafine Condensation Particle Counter 3025 A (CPC) och var nödvändigt för att hålla koncentrationen inom det mätbara området. För att få hög tidsupplösning på avläsningen från CPC:n har individuella pulser räknats. Dessa …
… can limit the life length of tiled drainage are for example elutriation of particles, choked-up by roots or folding out by ferrous oxide. (Kvarnemo 1983) In my work, I have select to retype the underdrainage implementation and upright calculations for what one underdrainage …
