… is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low …
… with Kalman filtering using an error model and the other is a centralized particle filter using an all-embracing model of the vehicle. The two methods have been evaluated and compared. Test results show that the two methods perform equivalently. The autonomous travel is …
ett odlingsförsök vid tre rödfyrshögar i Västra Götalands län
… were analyzed for the total content of the above-mentioned trace elements. Particle size distribution, organic matter content and pH was also determined for the growth medium samples. The growth of the vegetables was, as expected, higher with the treatment with burnt alun shale …
en biologisk bekämpningsmetod mot ogräs
… material (soil) was performed for analyses of plant nutrient content, pH, and particle size distribution. In addition to the investigation at Bäcklösa, also the soils of three other transforming stations were analysed for particle size distribution. Those stations were …

… were produced describing the probability for the transit time for a water particle between a certain location in the aquifer and the pumping well. A comparison with the tracer experiment shows higher simulated transport times implying the need for improved model calibration. The …
… registered. Faecal samples were later analysed by a wet sieving technique. All particles longer than 1 cm and all kernels were counted to evaluate rumen function of the cows. All data concerning consumption, milk production and faecal characteristics were analysed with a mixed …
… of 40 m, be able to function even if the water is contaminated by fibres and particles and share the same drivetrain as the existing dewatering pump 2610, produced by ITT Flygt. To match the demands in dirty water with particles and fibres requires a new grinder to be designed …
Teoretisk analys och praktisk försök
The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures. The suggested system gives opportunities to introduce biofuels in new areas. Main components in the suggested system is a …
… and the shaft. The friction shim is made of a thin steel foil with diamond particles fixed in a nickel matrix on both sides. The thesis evaluates several questions concerning the new arrangement. Some of the questions concerns different bearing selections, internal radial …
… the Härstad wetland was to a larger degree than in the Åmot wetland bound to particles, facilitating P retention through sedimentation. According to the tracer study, the Härstad wetland has a hydraulic efficency (?) of about 0,13 which means it has a low hydraulic efficiency …
… shown both theoretically and in laboratory environments that the sizes of the particles in the oil mist influences the performance of separation. This is to be verified under applied circumstances as well. The separators also have in most cases, after the centrifugal separation …
… in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated …
… from the consistency of the faeces and faecal content of long (>10 mm) particles, whole and partial grains.The calves fed the DDGS diet had higher growth rates than calves fed the SBM or SSB diets (1.34 kg vs. 1.21 kg and 1.25 kg per day, P < 0.01). Calves fed DDGS also had a …
… nuclear power plant at Chernobyl explod-ed and large amounts of radioactive particles were then released into the atmosphere due to both the explosion as well as the consecutive fire of the graphite core. A cloud of radioac-tivity was spread over the northern hemisphere …
… The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting …
