Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

The sites I visit turned into routines a long time ago. Everywhere someone has decided what should be there and what will not fit. I retreat into my daydreams, away from everyday life. A longing for something different, something wonderful. I decided to go where I've never been, searching for something unknown.

The purpose of this study is to study the Swedish Tax information campaigns in 2010-2012. Questions about what worked better than others, and what impact this has had has been set up. The study shows that work has essentially divorced by 2011,worked with a significant amount of local material. This work had an impact on mass media published locally in newspapers. This work fits well with research in the area showing that messages should be tailored to the target audience and capture the target group's interest.

The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.

The purpose of this study is to explore the relations between foster parents and their foster children, what kind of motivation there is behind their involvement in foster children, how they experience the commission and what good parenting mean to them. The study is including eight foster parents. They have experience of both long and short placement of foster children. The results show that all these foster families have at least one child that they have a good relationship with. It is important to know that those children either have spent many years in foster families or arrived to foster families when they were very young or as infants.

SecRePac is a household appliance that simplifies sorting of packaging such as milk, juice and yogurt containers. By shredding the packages SecRePac reduces its volume uptake both in the home and at the recycling station. This leads to minimization of both transports to the recycling stations and truck transport for emptying the containers at the recycling station.The greenhouse effect deteriorates and becomes worse and worse leading to extreme climate changes and natural disasters such as floods as an example. Carbon dioxide emissions are the major reason for this and at least 30 percent of all these emissions come directly from transports. In the EU carbon emissions has decreased in the past few years.

The aim of this thesis is to present, investigate and especially to analyse the legal rules that apply in the process of changing of the generation of the ownership of Swedish agriculture and forestry family business. The methods that this study include are: unplanned succession of ownership, i.e. inheritance, and planned succession of ownership, i.e. gift and purchase. The succession method that is the most cost efficient must be established in every single case depending on the situation of the current owners and the successors.

Dementia may cause difficulties in communicating. People suffering from dementia are therefore often described as being unable to take part in meaningful conversation. The responsibility to create understanding in a conversation is shared by all participants. By means of different strategies, participants in conversation can construct understanding through collaboration. How these strategies are utilized in conversation where one or more of the participants suffer from dementia is relatively unknown.

The aim of this study is to examine a number of Swedish working public librarians and compare them with some popular standard images of librarians. In this project we have been working in line with these three questions: How do the librarians describe themselves and how can the descriptions be interpreted? What images are the most common and repetitive, according to earlier research? What differences and similarities are there between the images of the librarians and the working librarians? To answer the questions we have performed seven qualitative interviews with working librarians and collected relevant literature that presents various portrayals of librarians. To interpret the interviews we have used Pierre Bourdieus theories of social space, social fields, habitus and the cultural, academic, social and the economic capitals, as well as the connection between individual taste, class and social power. The conclusions of the collected material of earlier research and the interpreted material from the interviews have been compared and discussed.

Utvecklingen av delade mobilitetstj?nster, s?som bildelning, cykeldelning och mikromobilitet, har framh?llits som lovande l?sningar f?r att adressera de utmaningar som pr?glar urbana transportsystem. Dock visar tidigare forskning att dessa tj?nster huvudsakligen anv?nds av m?n. Det finns ocks? en brist p? kunskap om varf?r kvinnor ?r underrepresenterade i anv?ndningen av delade mobilitetstj?nster och hur dessa tj?nster kan anpassas f?r att gynna kvinnors r?rlighet. Denna uppsats bidrar till att ?ka f?rst?else f?r de hinder som begr?nsar kvinnors j?mst?llda anv?ndning av delade mobilitetstj?nster samt vilka anpassningar som kan g?ras f?r att b?ttre tillgodose kvinnors r?rlighet.

My essay is on the subject of teachers work environment with focus on noise and communication. In the essay questions are raised on how a teacher can influence his or hers noisy work environment. A school is a large work place with many employees and is owned and administered by the county municipality which is an even bigger workplace. How big an acting space does a teacher have in such a large organization?My methods of research on these questions have been to conduct interviews and analyzing documentation from The Swedish Work Environment Authority.

The purpose of this paper is to study the image of Strindberg that is conveyed in four different textbooks for the upper secondary school. How do the teaching authors choose to portray Strindberg? Do they focus on any one particular aspect of his writing? Adjacent to this a subsidiary aim is to see if teaching authors highlight the fictional nature of Strindberg?s works or choose to encourage a biographical interpretation. The work consists of a study of four literary history textbooks in the subject of Swedish for the upper secondary school, from 2000 to 2012. In the selected material the sections focusing on Strindberg and his writings are closely read and critically analysed.

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

Concentration problems have been discussed from a variety of angles and have been problemized in different ways. One approach is to place the major part of the problem on the child independent of its environment. The terms used as an explanatory model are ?attention disorder, impulsiveness, difficulty at finding suitable activity levels, difficulty in understanding rules and instructions? (Kadesjö 2007). Others place the root of the problem in the environment prevalent at pre-school and school.

Shopping malls have been growing in numbers during the last few decades. As an effect, consumers are increasingly placing a greater amount of their purchases under one roof. The problem is that stores within these malls have to fight for the consumers' attention in competition with all the other stores. Thus, making consumers noticing their store is critical for success. Creating attention through floor advertising could be a potential way of doing so.
