32	Fuktomlagringar i välisolerade ytterväggar : En undersökning för att fastställa en rimlig inbyggnadsfuktkvoti träreglar med fuktsimuleringsprogrammet Wufi 2D / Moisture rearrangements in exterior walls Forsberg, Tomas January 2011 (has links) To save energy it’s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth. The purpose of this study was to investigate what is a reasonable moisture content in wood studs in four different well-insulated exterior walls. It has also been investigated how moisture rearrangements effect the exterior walls. The software Wufi2D, which does moisture-simulations, was used to collect data. The results have been analyzed in Wufi Bio which showed that the moisture content should be somewhere between 12.5 to 18.5%, depending on how the wall is built. The conclusions are that windbreaks vapor resistivity is essential for what is a reasonable built in moisture content in the wood studs. Depending on the materials that are used, it´s important to consider how much moisture the wall construction contains. cellulose fibers moisture rearrangements built-in moisture mineral wool wood studs windbreaks well insulated exterior walls Wufi2D Wufi Bio. cellulosafibrer fuktomlagringar inbyggnadsfuktkvot mineralull träreglar vindskydd välisolerade ytterväggar Wufi2D Wufi Bio.

33	Windbreaks May Increase Water Yield from the Grassland Islands in Arizona's Mixed Conifer Forests Thompson, J. R., Knipe, O. D., Johnson, Phil M. 01 May 1976 (has links) From the Proceedings of the 1976 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona Academy of Science - April 29-May 1, 1976, Tucson, Arizona / The general hydrologic characteristics, selected climatic factors, and soil properties of the high-elevation grasslands are compared to the surrounding forest. Evidence shows that water yield could be increased by 1-1/2 to 2 inches if snow could be held where it falls. It may be possible to establish tree windbreaks in the grassland by altering the microclimate during establishment, and introducing mycorrhiza with the planted seedlings. This conclusion is supported by good survival in a 2-year planting trial. Hydrology -- Arizona. Water resources development -- Arizona. Hydrology -- Southwestern states.
