Svårigheter vid färgundersökning av arkitekturbundet måleri Fallstudie: Färgundersökning av en lågerhuggen gördellist i södra valvet på Stockholms slott
This bachelor thesis discusses various difficulties with architectural paint research. The difficulties are exemplified through a case study ? a paint research on a furrowed string-course in the southern vault of the Royal Palace of Stockholm, which was carried out November ? March 2009-2010 on behalf of Statens Fastighetsverk. The paint research was made in order to receive information about the string-course and to get inspiration for a renewed color scheme on it. The base material of the string-course is Gotlandic sandstone and the Surface of it is furrowed.

To be a farmer and have suckler cows is a difficult combination especially considering the economy. Because of the increased feed costs, the margins have become tighter. The meat price from beef cattle has increased a little when this text is written (spring, 2008), but not so much that it covers the cost for feed etc.
I have a small suckler cow production on approximately 30 cows and 2 bulls plus followers as a part-time business. The herd is tied in the old dairy stable built in the late seventies.
Investigation of Syndecan-1 Ectodomain Isolated from Chinese Hamster Ovary (CHO) Cell Culture Medium
Syndecan-1 is a cell Surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell Surface by metalloproteinases in a process known as shedding.
Möjlig kvittblivning och eftermarknad av ridbaneunderlag - topplager
The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the Surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, Surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

DETEKTERA MERA! : - En studie av LigandTracer® och andra vanliga detektionstekniker för interaktion inom antikroppsutveckling
Ridgeview Instruments AB är ett företag, med säte i Uppsala, som bland annat utvecklar mjukvara för detektionsanalys och detektionsinstrumenten LigandTracer®. Instrumenten detekterar cellinteraktioner i realtid och tillhandahåller information om hur interaktion mellan undersökt ligand och receptor sker. LigandTracer® används bland annat vid cancerstudier och affinitetsstudier av antikroppsinbindning till antigener på celler. LigandTracer® och teknologin bakom den har studerats för att hitta de främsta styrkorna samt utvecklingsområden i jämförelse med andra detektionstekniker. Dessa tekniker är Surface plasmon resonance, BioLayer Interferometry, quartz crystal microbalance samt Surface acoustic wave. Främsta styrkan hos detektion med LigandTracer® är att stor mängd data som beskriver interaktionerna erhålls.
Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie
Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.

Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free Surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil Surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
Övertoner i elnät vid Skellefteå lasarett : Harmonics in power grids at Skellefteå Hospital
The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar Surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.
Områdesinbäddning för ODE
This paper gives an introduction to the theory of minimal Surfaces. It is in- tended for undergraduate students with some basic knowledge of differential geometry and complex analysis.After defining the concept of minimal Surface and giving a brief histo- rical survey, we look at some well-known minimal Surfaces and a few of their characteristic properties. The connection between minimal Surfaces and harmonic functions is discussed and the Weierstrass-Enneper represen- tation formulas are introduced. We also present Bjo?rling?s problem and give some examples. .
Geokemin inom osorterade cirklar : Analys av tungmetallers distribution inom jordprofiler tagna från Abiskoområdet, nordvästra Sverige
The Arctic region appears as a pristine remote environment, yet there is increasing evidence that it is greatly impacted by pollution such as lead (Pb) and mercury (Hg). In this environment deposition of Hg has increased threefold since the last industrial revolution. In this study five cryosolic soil profiles within non-sorted circles (NSC) in the Abisko region, northwest of Sweden, has been analyzed to improve our understanding regarding how pollutants are distributed within such type of soil. The soil samples have been analyzed with the use of X-ray fluorescence analysis (XRF), for the measurements of the total concentrations of e.g. lead (Pb) and zirconium (Zr).
Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat
Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.
Införande av mjuka golv för mjölkkor : en fallstudie
Soft rubber flooring have gained in popularity over the last years. Rubber flooring al-lows cow to move more freely without slipping and improves claw and leg health. The purpose of this study was to investigate the influence of a stepwise introduktion of soft flooring on cow`s placement in cow houses with robotic milking.
A case study was carried out in a herd in northern Sweden with 41 cows. Observations were made every 15 minutes between 09.00 and 16.00 concering cow placement in cu-bicles, in cubicle alley, in feeding alley and in feeding alley with the head through feed-ing gate. One observation period was carried out per flooring alternativ: 1) all concrete slatted floor, 2) rubber slatted floor in feeding alley and concrete slatted floor in cubicle alley and 3) rubber slatted floors in feeding alley and solid rubber floors in cubicle alley.
The study showed that 6 %-units fewer cows lay in the cubicles when the feeding alley Surface was slatted rubber.
