C?RONIS BIVAXFERNISSA En unders?kning av inneh?ll, l?slighet och ?ldringsegenskaper
The aim of this study is to provide a comprehensive overview of C?ronis beeswax varnish by Lefranc &
Bourgeois; its contents, aging properties, solubility, and possible removal methods, with G?teborgs
Konstmuseum?s ?Gothenburg Museum of Art? collection as the stud??s material? The purpose of the
study is to provide a basis for decision-making regarding the treatment of works treated with C?ronis
wax varnish. The study is based on contemporary conservation theory and interpretation-based
decision-making and utilizes FTIR, microscopy, and solubility tests to examine the properties of the
varnish. The study shows that C?ronis does not appear to be harmful to the treated works and has
retained its solubility properties and transparency over time.
Effektiv provningsmetodik för växelföringsdamasker
Completed durability testing of gearshift gaiters at Kongsberg Automotive in Mullsjö, is sometimes leading to discussions regarding whether or not a gaiter is supposed to be a pass or a fail. That is because the current pass/fail-criterion are a bit vague. A durability test takes around 4-5 weeks to complete which is a long time if the tested material does not pass the test and a new material has to be tested instead. Stricter pass/fail-criterions and a faster testing method for the Materials are therefore desired.In order to develop a durable pass/fail criteria, seven already judged gaiters were chosen. Every one of the gaiters was put through detailed analysis, after which there were a new assessment of the gaiters.
Representeras ditt yrke? : - en kvantitativ studie om vilka yrken som representeras mest respektive minst i facktidskriften DIK-forum
The aim of our study has been to see how DIK-forum represents the occupational groups that are represented in the frames of the trade journal. We have, to find out the phenomenon, done a content analysis by looking into 18 numbers of DIK-forum from year 2006 and 2007. The 18 strategically chosen journals was enough to give us a statistic result that we later on could generalize over those two years of DIK-forum. Totally there were 818 articles, news items and vacant advertisements that made the central point of this study. By these Materials have we studied the representation of the occupational groups to find out if there were any over- and/or under represented groups, and also if the publications of the material were directed to the students or to the occupational groups in these trade journals.In our study the results shows that the trade journal DIK-forum does not represent all the occupational groups at the same level.
Miljödifferentierad fastighetsskatt
It is essential to reuse- and recycles residues to decrease the amount of deposit Materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.
Sambandet mellan saldodifferenser och effektivitet : En fallstudie på utomhuslager inom Sandvik Materials Technology
To meet the needs and demands of the costumer, accurate information about how much is available in stock is necessary. When the information in the system does not match the physical inventory, inventory inaccuracy occurs. Inventory inaccuracy is common among companies and may contribute to increased labor cost, excess inventory, production disruptions, waste of time, late deliveries, poor service and lost customers.The purpose of this study is to identify contributing factors to inventory inaccuracy for business with outdoor storage. The study also aims to investigate how efficiency factors can reduce the inventory inaccuracy for business with outdoor storage.A case study was conducted to answer the purpose. A company in the steel industry was chosen to examine inventory inaccuracy on business with outdoor storage.

Utveckling av golvlucka för hoppgropssystem i kommunal idrottshall
In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood Materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.
Optimering av driftläggningar i Fortums nät
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of Materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
