… on farm and factory level. We have studied beans and pea at two different moisture levels, 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 …
… by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain …
… or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning. The results confirmed the …
En byggnadsfysikalisk bedömning och mätningar om temperatur, och fukt analys på ytterväggarna
… passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist. Reason for doing this investigation is to see if passive houses fulfill the building codes regarding moisture, and temperature changes, and to find in …
Brand- och fuktegenskaper i passivhuskonstruktion
This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive …
Design och utvärdering av EAS-alarmteknologi för fuktdetektering
… or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have …
Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början
… Climate and Energy was suitable for energy simulations of old buildings. The moisture balance of the outer walls was calculated manually to see if the supplemental insulation constituted a risk when it came to the moisture sensitivity of the construction. The result of the …
… was examined and evaluated. Furthermore it was analysed however the initial moisture content influence the results. The water repellence in the wood samples was also tested with a drip test. In this study was a total of 40 wood samples with the dimensions 500x50x25 mm used, 20 …
en studie av olika beståndstyper inom Hamra kronopark, Dalarna
… could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to …
generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten
… streams of first order in Värmland can be summarized as having a fresh soil moisture class and productive soil with uniseriate coniferous forests and a grass-herb type vegetation class. Dead wood was not common occurring in the study area. Machine tracks were found in 12 % of …
… done for microbes and germination. The six batches were harvested at average moisture contents from 17 to 20 %. No quality damages were detected during drying in the examined dryers, but not all of the batches were dried to 14 % moisture content, which might have caused quality …
grundläggande studier
… the pellets were then evaluated from the chosen parameters; type of sawdust, moisture content, compaction pressure and temperature. During a limited variation of process and raw material parameters pellets were produced in a laboratory scaled press. Density, compression strength …
en jämförelse av ett silotorksystem med omrörare och en konventionell anläggning
… This study also aims to answer questions about the impact of variations in moisture contents on the economic result of investing in the different systems. The impact of the total acreage available and how the optimal cropping plan is affected by investments in different types of …
… uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable. The resulting simulator fulfils the requirements and enables better repeatability …
Hårdgörning av trä syftar till att göra materialet hårdare. Detta går att åstadkomma genom komprimering, det komprimerade materialet tenderar dock att återgå mot sin ursprungsform då materialet utsätts för fukt om ingen låsning sker. Låsningen kan ske mekaniskt i en …
