Abstract.The levels of dioxin and comparable substances rose to a large extent in our environment during the second half of the 20'Th century. This was the result of the synthesis of, and careless usage of these substances in cooling fluids, hydraulics, pesticides etc. Background levels of dioxins and furans in sealed samples prior to this era suggest that former sources of these substances existed. Salt glazing is a method of adding a smooth acid resistant exterior to stoneware ceramics. The technique has been in use since the 16'Th century, maybe even earlier than that.

The information technique is developing at a fast pace and almost all new technique is being welcomed with opened arms. The newest on the market is the tablet device, it´s a device used for surfing the web, sending email, watching movies and playing games. It is now also being used in some schools for educational purposes. My research goal has been to find out how the teachers feel about using the tablet device for educational purposes. I have conducted interviews to find the answers to my questions.

Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.

The development of the web has become an attractive area, with continuously and rapid development in the area it has led to a big change in the way of learning. Learning is a concept with many definitions, but a definition that is many at hand is that learning means that individuals seeking new knowledge and experiences that shape their goals, behavior and environment.With the development of the web a new way of learning emerged, E-learning. E-learning integrates information technology with the traditional learning to offers a flexible way of learning for students where they won't be dependent on time, place or others issues that would prevent their learning. E-learning takes shape of an application, LMS (Learning Management System). Today LMS are widely used in many universities, but with new technique comes new problems. The constant developments of the LMS have made the decision to use LMS difficult.

Prefabricering eller platsbyggt hus? Många ställer sig den frågan. Vad finns det för fördelar respektive nackdelar med prefabgentemot platsbyggt hus? Vilka ritningar behövs och hur går man tillväga?Detta examensarbete är en framtagning på hur man anpassar ett småhus till prefabricering.Platsbyggt hus är ett hus som byggs på plats. Material fraktas dit, förvaras och kapas.Den vanligaste byggmetoden för byggande av hus.Prefabricering av hus är däremot ett hus som byggs i en fabrik eller industri.

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.

AbstractBackgroundThe Swedish district heat market of today is a subject being discussed regarding the reasonableness of the heat district supplier?s price settings. The issue is currently on a government level where a new investigation is being executed at the time of writing. Many real estate owners are growing tired of the situation where the heat district suppliers are taking advantage of their monopoly position, thus feeling that the price of district heating has been increasing far too much for many years. The market can be described as a natural monopoly because the real estate owner has no possibility to choose another supplier if they are unsatisfied with the present.

Drawing on earlier research, and using observations as the method, this study presents a design of a nature playscape for children. Applying outdoor pedagogy to the fundamental structure of a specific location, the study proposes a design of a playscape, over a more obvious design, for instance one based around a quiz walk.The theoretical framework is Gibson?s theory of affordance, and the goal has been to create a "play flow". The study concludes that spatial rhetorics can be an important tool when teaching children about nature..

This thesis is about practising on a different level to get an insight to what techniques might work for me as a double bass player. It is about discovering how to use your brain into playing at your best level. I practised both talking and singing to myself and read a lot about thinking and hearing not only the music but every note before playing. The thesis idea came from not having a technique that worked for me while practising alone. I wondered why it is such a difference between what we do at the lessons and what I do when practising by myself..

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. It can be divided in different subtypes. The most common type is superficial and is most frequently occurring on the trunk and on the face. In severe cases it can be difficult to differentiate basal cell carcinoma from other skin tumors, therefore a skin biopsy is conclusive diagnostic method. In terms of treatment, curettage is a common non-surgical treatment of basal cell carcinoma.

This thesis, drawing from several empirical investigations, reaches the conclusion that there seems to be a positive correlation between the level of democracy and the level of state capacity in Latin American countries. This correlation is explained by a hypothesis derived from Rational Choice theory. With some important caveats, this conclusion is then applied to the discussion about democracy as a form of government. Within democracy, the thesis also offers an insight into different electoral systems and its possible implications, mostly on a theoretical level. The thesis only exists in swedish as of yet..

There is an old saying, that after Epaminondas nothing was ever the same again. In this thesis I will focus on three questions: "Epaminondas the man." Who was he? "Epaminondas the general." How did he change the technique of warfare that made it possible to beat the Spartans? "Epaminondas, founder of cities and wall-builder." How did he build the walls around the cities he initiated, that made them resist enemy attacks for many years to come?While seeking the answers to yhese questions I will make a contextual analysis to get the historical background to all the phenomina involved..

ABSTRACTIntroduction: Preoperative hand disinfection aims to prevent surgical site infections. After the preparing hand wash, drying is performed using an aseptic technique. It?s important to dry hands thoroughly in order to achieve the full effect of the alcohol based hand disinfection. Due to the lack of a evidence-based guideline on this procedure, the hand drying techniques differ among operating theatre nurses, depending on which technique seen as the most appropriate.
