Vattentäthet är en mycket eftersträvad komfortegenskap inom funktionsplagg idag. Utveckling av nya material och funktioner syns ständigt på marknaden, funktioner som ska förbättra denna vattentäta egenskap och låta den kvarstå efter hårda väderförhållanden, tvätt och andra slitage. Tejpade sömmar är en faktor som är okänt för många, då det vanligtvis inte syns på utsidan. En vattentät jacka hade dock inte fått sitt namn om det inte vore för denna funktion. De flesta sydda plagg som kräver att vatten inte ska läcka in, är alltså täckta med en tejp på baksidan av sömmen och sömsmånen.

This final project is an investigation about the responsibility in rooms where the walls and floors are exposed or partly exposed to irrigation of water, as a bathroom, laundry room and WC. The cost for all water damage is valued for 5 000 000 000 SEK each year. How is this possible with all information about the problem and good materials? Who is responsible? Incites had been made in the subject throw reading reports and participation in courses about how to make a room mention above. Discussions have been made with workers in the trade of making the walls waterproof.The conclusion in the rapport is about who´s responsible for the damages and will pay the cost of the renovation. The responsibility is discussed between the contractor and the insurance company.

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Tylö AB is the leading manufactor of sauna cabins in Europe, but there is a lack of a sauna lightning produced by Tylö. The project of developing a new sauna lightning series was assigned two students at the developmentengineering program at Halmstad University. The main problem with lightning in the sauna is the heat and security aspect. The selection fell on LED technology as the lightning source, thanks to its small measures and low heat emission. The work of constructing of a lightning armature which the capability of cooling down the LED lightning was carried out during autumn ?06 and spring ?07.

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.

The aim with this thesis is to investigate the risk management at the department Road construction, The National Road Administration Region Mälardalen. The aim is also to study how the risk management could be improved to better support the project leaders. Included in theses aims is to examine potential problems with the current risk management and to suggest changes. It is of utter importance to define the concept of risk, to study how risk can be measured and in which ways risk can be analyzed. In doing so, a literary study has be done and fourteen respondents has been interviewed.Risk is to be seen more as a concept than a quantity.

The aim with this literature review is to describe the ensilage process in a bunker silo. The process from harvest and chopping to filling and unloading the silo is explained. The sealing of the bunker silo plays an important role for the final quality of the silage. This review covers some of the techniques used. There are many silage additives on the market, some of them are presented including how they act in the ensilage process.

Gtherm is an innovation company who has an unique air heat exchanger underdevelopment. The purpose of this thesis is to provide data of suitable motors for theheat exchanger and to find suitable motor suppliers.A motor specification was designed. It is an important basis for the search of suitablemotors. A compilation was made of nine motor suppliers and the suitable motorsfrom those. The compilation can be used by GTherm in their choice of suppliers andmotors.The compilation of the demands on the motor and analysis of suppliers indicated thatthere were no standard motors available to GTherms air heat exchanger.

This report is focusing upon relining from a client?s point of view. Potential buyers are given a presentation of the different methods available today together with a general briefing describing the process. An important part of this report are the interviews that took place with already established customers. Property owners, managers, pipe cleaners, and project managers whom all been in contact with relining have answered the questions given along with their own thoughts and have also given recommendations of other persons to talk to.

Previously when I have made proposals for privately owned gardens, I have found it difficult to find strong, extensive designs and to work with room and space. Since this is the field within which I am going to work in the future I feel that I need more experience, reference material and ideas on how I, in an early stage of the working process, can work with and consider room and space. The aim of this project has therefore been to procure experience, reference material and ideas for design of a garden in relation to space. To procure experience and reference material I have, during the fall of 2008, made two incredible study tours to France and to Japan. I have interviewed the landscaping architect Maria Arborgh and studied literature. I have also used a garden outside of Gothenburg in which I have been able to try out different thoughts and ideas regarding shape that have appeared during the course of my work. My conclusions about landscaping are that you should first find the different functions in the garden. The next step is to find an overall theme or shape, use a small number of materials, build a room with sealing, walls and portals with the help of vertical elements e.g.

Silage is today a common feed for different animals. A general way of storing silage is in bunker silos covered with polyethylene film. The covering and uncovering is labour intensive and it is often difficult to get the silo properly sealed. Because of these reasons many American farmers leave their silos uncovered and accept the losses accompanied. One purpose of this study was therefore to examine if it sometimes can be justified to leave bunker silos uncovered.
