… with master painters knowledge were gained about the way of work with the layers between the oil paint and lime plaster.Test samples were taken from the wall to find out if the reason of the difficulty with the fixation could bee seen in microscope. Two tests were casted into …
… is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are …
På uppdrag av institutionen för geologiska vetenskaper Stockholms universitet
… biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth’s past climate, information that can be used to predict future climate change and to estimate …
… eskers in the inland of Västerbotten County in northern Sweden. The top layers of big eskers along the valleys of Öre River, Ume River and Vindel River were investigated through shallow digging. Findings were investigated through field assessment and soil analysis and many …
… of radiation damage, DPA (Displacement Per Atom), for various positions and layers. The results show good reliability, except for at the outer layers of the vessel wall, where the traditional measure underestimates the radiation damage. Inspections are carried out in connection …
… construction is a sandwich element where the concrete is made ??up of three layers. Two external high-strength layers and a middle layer of low-strength concrete. The result is compared with three different concrete recipes. The environmental data obtained is then integrated …
Två fallstudier inom historisk arkeologi i Umeås 1800-tal
… chemistry methods were used to analyse soil samples from undisturbed cultural layers in a construction trench at the old port of Umeå. A thick burnt layer consisted of charcoal, oats and weeds, suggesting storage and possibly intended as food for horses. Oat and pea were …
En utredning av påverkan från möjliga osäkerheter i befintlig information
… was calculated based on two types of information: descriptions of the layers in borehole profiles and information from sieve analyses. The obtained values were then compared to a rough estimate based on information about groundwater flow and hydraulic gradient. The compilation …
… of Ultem? is highest when wear occurs parallel to the direction of the printed layers. In contrast, the experiment shows that the wear is about three times larger in Ultem? than in POM. The highest tensile strength of Ultem? is also found in the direction of the printed layers …
… different locations in the lake. The sediment cores were divided in three layers; 0-3, 3-10 and 10-20 cm. Pore water was extracted and redox sensitive measurements were conducted in a glove-box in an oxygen free atmosphere. Subsamples from the layers in the sediment were …
… such as linings, strip linings and reinforcements between separated layers. As with all conservation measures, these techniques also demonstrate advantages and disadvantages which can be utilized to achieve the desired result for a particular object. With continued research …
analys och metodutveckling
… and evaluated on different parts of the wallpapers to adhere the different layers. MC 2.5% generally showed good adhesion in combination with good flexibility and a minor amount of change in colour on the printed surface but was not always the appropriate choice
… affects the decomposition of organic matter below ground in different soil layers and root diameters, and investigate the possibilities that addition of ammonium sulphate could lead to a decreasing potential of carbon mineralisation. The study was conducted is in Skogaby, which …
en webbaserad GIS-applikation för kalknings- och försurningsinformation i Kronobergs län
… As it was found that ArcIMS lack the ability to interact with two map layers to analyse the geographical relationship of the objects, an exemple of an GIS based analysis was handled outside the program. The analysis concerned the impact of air pollutions on the acidification in …
… from other factors such as spreading of contaminant between different layers of soil. Since degradation failed to be quantified, natural attenuation can not be recommended as a safe remediation method at the considered site without further investigations.
