With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.

The aim of this thesis is to investigate how students in higher education use talking books. This has been inves-tigated through qualitative interviews with nine students. The intention has been to find out how they use talk-ing books and why they have chosen to do it in the way they have, looking specifically on whether there are strategies shared by most of the interviewees.As a theoretical basis of the thesis I have chosen a study, described by Sigrid Hongset, where dyslectic pu-pils tried using printed text and text on tape, as well as both simultaneously. George Kingsley Zipfs ?Principle of least effort? will act as a supplemental theory.The interviews show that the students use talking books in different ways.

Vaccination är en av de mest kostnadseffektiva åtgärderna inom sjukvården. Sveriges vaccinationsprogram innefattar tio sjukdomar och barnets femte dos ges vid fem års ålder. Barn i förskoleåldern befinner sig i ett utvecklingsstadium vilket kan försvåra vaccination. Tidigare studier beskriver svårigheter och den stress sjuksköterskor upplever i samband med vaccination av barn, kunskapsbrist finns däremot kring hur barnen bör hanteras. Syftet med studien var att utifrån betydelsefulla händelser beskriva barnhälsovårdssköterskans (BHVsköterskans) erfarenheter och agerande vid vaccination av förskolebarn som inte vill medverka.

This Master thesis has been carried out at Scania CV AB in Södertälje, in collaboration withKTH, The Royal Institute of Technology, Stockholm. The focus of this Master thesis isSetBased Concurrent Engineering(SBCE), with the purpose of answering the questions: what isSBCE, how does it work, and for what purposes is it applied.It was early established thatSBCE is often included as a part of Lean product development,which in its turn is often related to Toyota?s way of working. TheSBCE method includesworking with multiple solutions in parallel, eliminating weak alternatives throughout thewhole process. In opposite to a conventional product development process, where it iscommon one at an early stage tries to identify and choose the most promising alternative.Despite the appearance ofSBCE as a resource consuming method, figures from Toyotaindicates the opposite, thatSBCE is in fact a very effective way of working compared to othermore traditional methods.The process of this Master thesis was divided into three phases.

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

Abstract   Cinematic time is the most complex of all: it is composed of public time (clock), personal time (experienced) and in addition, it can run backwards, be contingent, stored and (re)created. The present study examines some aspects of cinematic time, with special reference to the instant, the moment and the present. The strictly defined instant or moment does not exist. It is a passage between the past and the future and it is impossible to record on film or a photograph. One example is the moment of death, which is an abstraction with zero duration.

This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.

AbstractWorking with child and youth welfare is one of the most difficult challenges a social worker might face in the field of social work. Those who work with child and youth welfare are more exposed to stress and burnout than other comparable human service occupations. Research links the prevalence of stress and burnout to several key variables, such as demographics, working conditions and personality factors. In contrast, even though social workers in this field face many negative work-related problems they report a high job satisfaction. The aim of this study is to examine how uplifting and straining experiences affect social workers, who work with child and youth welfare, through the use of The Critical Incident Technique and interviews.

Denna uppsats försöker besvara frågeställningen varför en del studenter vid Karlstads universitet väljer att ta ut sin examen vid något annat lärosäte. Vi belyser bytesprocessen som leder respondenterna i undersökningen fram till ett faktiskt byte, från det att tanken föds, till att studenten etablerar sig vid ett nytt lärosäte. Med hjälp av djupintervjuer hittar vi anledningar till varför byten sker, antingen av praktiska skäl eller så är det tron att en examen från ett äldre lärosäte, med högre status, ger ett försprång in i karriären.Utifrån teorier som valts inom exempelvis relationsmarknadsföring, image, kundnöjdhet och bytesbeteende- framför allt SPAT (Switching Path Analysis Technique) analyserar vi informationen och underbygger resultaten. Längs undersökningens gång har vi modifierat SPAT-modellen och lagt till flera variabler. Detta för att den ska passa in på just bytesprocessen hos högskolestuderande, vilket har givit oss en tydligare bild över processen.Det framkommer tydligt under studiens gång att flera av studenterna väljer att byta universitet för att ta ut sin examen vid ett universitet med i deras ögon högre status.

Molar Incisor Hypomineralization definieras som ett specifikt tillstånd orsakat av störningar i den tidiga fasen av emaljbildning av en eller flera permanenta första molarer med eller utan involvering av permanenta incisiver. Tidigare studier har visat att standardiserad intraoral fotograferingsteknik kan vara användbar för epidemiologiska studier av emaljdefekter. Denna studies syfte var att utveckla och utvärdera en fotografisk klassificering av allvarlighetsgraden av Molar Incisor Hypomineralization genom att studera metodens validitet och reliabilitet. 164, 10-12 åriga svenska barn granskades fotografiskt avseende prevalensen av Molar Incisor Hypomineralization. Först granskades endast första molarens ocklusalyta, därefter ocklusal- och buckalyta.

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

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.

The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.

Abstract          Background: End of life is difficult to establish in patients with dementia and many patients die due to complications related to the disease. To document that care are palliative in this group of patients is not common among nurses and physicians. This may depend on that the palliative course is extended and not similar to the palliative course common among patients with cancer. Aim: To describe how the registered staff in nursing homes document the care of persons with dementia in a late palliative phase. Method: A retrospective record study with a deductive approach.

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.
