En studie på spridning av partiklar genererade från brand
During a fire large amounts of particles and unhealthy agents occur. Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the …
… Annually about 50 000 tonnes are incinerated at the plant. Levels of airborne particles, metals present in the airborne particles, volatile organic compounds (VOC), and phosphine were measured in the air. Analysis of the bottom ash water including: pH, total phosphorus …
… An important factor that influences eating- and ruminating time is the particle size of the roughage. The aim of the study was to find out if particle size influences the behaviour of dairy heifers, in particular with regard to eating behaviour and abnormal behaviours. The study …
… far larger applications. As the process water contains quite large amount of particles, it is necessary to perform the filtration in different steps. The process water purifier is therefore composed of a module of coarse filtration and one of micro filtration. In the module of …

… the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis. Many models for feed management have been developed to secure that the animal …
… the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines. This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass …
… the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced. According to the result, there are areas with poor air quality even in smaller Swedish …
… in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill. The evaluation has been performed at the farms using their existing equipment where selected samples were taken. These where then sieved in order to …
Coenagrion larver med hjälp av borsten på framben och fötter?
… the branched setae. I used a microscope called SEM to be able to see the small particles on the different body parts. I separated the head and the right front leg from the rest of the body. When I was using the SEM I also took photos on the different body parts. My conclusion is …
Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the …
… and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance …
… (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to …
Parametrisering av en 3D-modell av ett cyklonfilter i SolidWorks för snabb framtagning av nya konstruktioner till Outotec Skellefteå
… and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air …
… The paste was formulated by evaluating the optimal combination of pigment particle size by using two different particle sizes. The particle sizes used in this paper is 42?m and 4?m with a variation in the silver content from 42?m and 10% to 4?m and 25% silver. The binder used is …
