Equine cutaneous melanomas arise much more often in horses with a grey coat color than in horses of other colors. Some scientists have in different studies come to the conclusion that the melanomas are neoplasms which can be classified by examining their histological and macroscopic features. The more defined and demarcated a tumor is, the more benign it tends to be. Other scientists believe that the skin lesions are the result of a pigmentation disorder that is linked to the greying of the coat color. According to this theory, the lesions are not malignant although they have the ability to metastasize.

The purpose of this study was to increase the understanding of the phenomenon that there are so many young people placed in institutions in Sweden despite the valuable knowledge regarding the problems and risks of doing so. The questions that follow in the essay were what guided the social workers to choose institutional placement for youngsters. It went on to also ask if this knowledge could contribute to an increased understanding of why there were so many young people placed in institutions despite the criticism from scientists. To accomplish the goal of the essay, former science in the subject was reported and six social workers within social services were interviewed. The material of the interviews was analyzed with help from the theory of human service organizations, street-level bureaucrats work situation and the new institutionalism.The result of the investigation showed that the social workers choices to place young people in institutions is guided by specific work and organizational factors connected with a belief in the helping function of the surroundings.

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

This essay deals with the subject of communication through Facebook. In this survey we studied 100 youths from Karlstad and their communication habits and behavior patterns on Facebook. The social network site Facebook has since its start in 2004 made a mark in modern communication. Today in 2010 the site has more than 500 million users. This paper wants to study what happens to other types of communication.

Efterbehandling på sprutbetongen skall enligt regelverk som BV-tunnel och Tunnel 2004 ske direkt efter sprutning. Fukthärdning av sprutbetongen behöver tillämpas då den relativa luftfuktigheten understiger 90 % vid betongytan. Fukthärdning skall då utföras så att betongytan ständigt är fuktig, under hela härdningsperioden fram tills att betongen har fått tillräcklig hållfasthet. Då cementet hydratiseras bildas olika kristaller som ger cementmaterialet dess hårdhet och hållfasthet. Med krympning menas här rörelser i betongen som orsakas av vattenavgång i form av avdunstning från betongen och genom kemiska reaktioner i hydratationsprocessen. Syftet med denna rapport har varit att studera effekten av varierande fukthärdning på sprutbetongen.

This study, a document analysis with a qualitative approach, explores children, under 18years, who have been subject to measures of child welfare in the city of Malmö during theyears 1935-1937. It also explores the school's role in this context. The questions that the studyis guided by is: How was children described in the Child Welfare documents in Malmö duringthe years 1935-1937? And what role did the school have in Child Welfare work and whatmotivated this? The theoretical approaches are Foucaults theories of power, control anddisciplining.It appears from the study that the school and child welfare authorities had a close cooperationwith the purpose to control the upbringing and disciplining of the children. It was through theupbringing that the deviant child would become a "normal", docile and good, industriouscitizen.

ABSTRACTAim: The aim of this study is to chart the experiences of Swedish general psychiatric care on a Swedish University hospital from a relative?s point of view. The study focus on how they are meet, satisfaction with and participation in the care. The study is done as an improvement project.Methods: The study was conducted by performing semi-structured interviews with eight close relatives to patients on a general psychiatric ward. The interviews lasted for 20-40 minutes.Results: The result shows that relatives are satisfied with the way they are meet by the staff on the ward, that they appreciate staff that are open, down to earth and are inviting to form a good relationship.

Background: Almost every 20th child is borne premature in Sweden, before the parents are ready to care for a new family member. The parents need to cope with the stress and anxiety of having their newborn child in the neonatal ward and influenced by nursing care of neonatal staff grow their parental role.Purpose: The aim of this study was to illustrate experiences of parenthood within the care of premature at the neonatal ward.Method: A review where 18 articles between 2000 and 2005 were chosen and examined. The articles were analysed according to VIPS, which facilitates the practical use of the result.Result: The study reveals that parenthood is experienced as a time dependent process with three phases, primary, secondary and tertiary, where the parent?s needs and experiences changed character. The parents experienced that they developed from passive to active in the care of the premature child when the neonatal staff guided their participation, gave information/education and support.

?Childs pedagogic material ? A qualitative study of child?s use of pedagogic materials available at five nursery schools and about their teachers thoughts about the display of the pedagogic material?In the nursery preschool the environment and the educational materials have always had a central place. That's why it has been chosen to study and observe five preschools and interview sex teachers, in an attempt to understand the teachers thought about the choice of material and the choices of material that the children used. The reason I do this is to see what the underlying idea about the materials the children use is, and why educators choose to make certain materials visible. The purpose of this study is to examine the educational materials that are used to stimulate children´s learning and examine what determines the choice of educational materials.

This thesis deals with the question of why the Swedish Academy Dictionary has its own Library when, for almost a hundred years, it has been located at the University Library of Lund. Looking at the library functions: librarian, users, room and books and their external factors: economy, internal actors, external actors and the development of the Swedish Academy Dictionary helped to shed light upon which relations between these factors have been important in the development of the library. The results show that there has not been a conscious plan behind the Library. A large number of the books in the Library was given by those who have worked at the Dictionary and also by their friends and collegues. Another part was given by the Swedish Academy and was partly gathered when the project was still in Stockholm.

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.

According to the curriculum the teachers have a responsibility to adjust the activities in the classroom in order to suit the pupils and to give them the means of assistance the pupils need to be successful in their learning. The teachers should also stimulate the interest to learn and support the pupils? self esteem. One of the problems a dyslectic pupil faces is an often weak self esteem. Another is the weak phonological awareness which makes it hard to fully understand the context and to recognize different phonemes when writing.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Automatic milking systems (AMS) are part of a growing trend in Sweden and the number of milk-producing farms is decreasing rapidly. One main reason for the AMS is its ability to facilitate work for the farmer. The effects of introduction prior to calving have not been documented earlier and farmers are not in agreement, however they seldom see a problem with the introduction. The aim of this report is to find differences between two groups of heifers, where one group is trained i.e. introduced to the AMS before calving and the other group is introduced after calving.
