There are many elderly buildings, particularly those constructed during the million program, in need of renovations and plumbing replacement. An alternative to the traditional plumbing replacement is the relatively new and untested technique called relining. The purpose of the study is to thoroughly investigate the different types of relining that are currently available on the market to help enhance Peab?s knowledge before purchasing relining services. The theoretical part of this report is based on relevant information provided from companies, previous studies, investigations and reports within the area.

Playfulness and curiosity in the usage of new technology and digital filmmaking has always been of great importance within these fields. There are many different media technologies that can form what the user wants to communicate in a certain context. One of these forms of expression that has increased in popularity from the early 20th century until today is the animation technique, Stop motion. Amateur filmmakers have also found an interest in using the technique. Our purpose has been to study the different aspects as to why young-adult amateur filmmakers have chosen stop motion as the way to express themselves.

Studiens syfte var att undersöka möjligheterna att använda intervjutekniken Repertory Grid Technique (RGT) som utvärderingsteknik för att utvärdera User Experience (UX) på distans. Detta gjordes genom att de föreställningar som en handledarstödd utvärdering resulterade i jämfördes med det resultat som uppnåddes genom en webbaserad variant av samma utvärdering. Studiens resultat visade på en svårighet för respondenterna i den webbaserade utvärderingen att formulera föreställningar som går att använda för analys av en produkts UX. Diskussionen pekar på en tänkbar lösning i form av förstudier som utförs med en mindre grupp av respondenter för att på detta sätt hjälpa utvärderarna att skapa sig en referensram att använda vid tolkningen av de föreställningar som sedan kan samlas in under en webbaserad utvärdering. Studien syftade även till att jämföra vilka aspekter kopplade till UX som utvärderingarna genererade, samtliga av dessa kopplades till subjektiva eller produktrelaterade aspekter..

This thesis is about a part of the marquetrytechnique, scorching. Scorching is made by heating up something, put a veneer into the heated substance and make a controlled burning. This technique is old but still used today and have according to me great potential for development. In my work I wanted to give the scorching greater room then I earlier have seen. I wanted the scorching to be the dominant ingredient for a decorative element in a piece of furniture or an interior.

Att behärska två språk och två länders syn på pedagogik är en bra förutsättning om man vill undersöka och jämföra dessa två länders syn på barn med funktionsnedsättning. Syftet med föreliggande uppsats är därmed att belysa hur skolans styrdokument i Sverige och i Ungern formulerar och beskriver barn med funktionsnedsättning. En del av syftet är också att finna likheter och skillnader mellan det svenska och det ungerska styrdokumentet.Som material till ändamålet används den nya svenska Skollagen (2010) och den ungerska Utbildningslagen (1993). Analysen genomfördes med analysverktyget diskursanalys där jag har analyserat språket som beskriver barn med funktionsnedsättning.Resultaten visar att båda skollagarna har en tydlig koppling till de gällande internationella dokumenten där allas lika värde poängteras. Den svenska Skollagen har dessutom en relationell och deltagande syn på funktionsnedsättning medan den ungerska Utbildningslagen, som är 17 år äldre än den svenska lagen, betonar en kompensatorisk och individinriktad syn..

There are today large amounts of contaminated sediments in the Baltic Sea. These contaminants are the result of many years industrial activity where the contaminants have not been taken care of and just released out in the water. When ports want to dredge in their fairways and harbor areas the contaminated sediments need to be considered since they are a environmental risk. The development in this area has been slow and new techniques have just recently made its way into dredging operations in the Baltic Sea region. As a result of this there are no clear methods for implementing new techniques today.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

The aim of this work is to take the first step into a development process, with the intention to find a way of making prehistoric soil fertility a variable in archaeological landscape analysis. A pilot study is performed on the Mälar basin area, where four topographical and geological factors are reclassified and then combined, resulting in a map which expresses a relative indication of agriculture potential. The map is then compared to the distribution of Migration Period graves and gold finds. This, however, does not mean that the technique is tied to a certain prehistoric period. Because the work is intrinsically experimental, the technique as a whole is finally discussed and evaluated, and suggestions of improvements and further studies are made..

Ett stort antal människor dör på grund av skador som de fått inom vården och som hade kunnat förebyggas. Det finns siffror som pekar på att dessa vårdskador överskrider antalet döda i trafiken. Vid Östergötlands landsting finns sedan år 2005 en fast enhet som arbetar med patientsäkerhet. En av deras uppgifter är att, tillsammans med berörd verksamhet, utföra händelseanalyser inför anmälningar av Lex Maria-fall. Den analysmetod som används av patientsäkerhetsenheten är uppbyggd på en epidemiologisk olycksmodell.Syftet med denna studie har varit att använda analysmetoden FRAM (Functional Resonance Accident Model), som är en systemisk analysmetod utarbetad av Erik Hollnagel, i en vårdrelaterad kontext, någonting som inte har gjorts tidigare.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.
