Swedish contract law is based on the main principle of freedom of contract, which means that a contract is built on a voluntary agreement of both parties. There are exceptions from the principle of freedom of contract. In some instances a party is obliged to contract (kontraheringsplikt), which also is the subject for this paper. Kontraheringsplikt can be described as an obligation for one of the parts in a relation to come to an agreement under normal circumstances with everyone who ask for it. The cases of kontraheringsplikt are rather different.

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.

The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

This essay deals with the issue of children and stress, and the impact that stress can have on children. The purpose has been to explore how I, in my role as teacher, can prevent children from developing stress in preschool, and how I can prevent stress to develop inside of my own department. My essay is structured as follows: First, I describe my practical work with children. Then I analyze some research literature on stress, and finally I reflect over what I have described earlier and try to connect the practical with the theoretical.In the practical part of this essay I describe the various events that I have observed during my work in preschool, where I have seen how stress can affect both children and teachers. Then I describe how the increasing size of children?s groups can create stress because of the noisy environment of the department.

Hur vi uppfattar vår omgivning påverkas av alla våra fem sinnen, där denna uppsats tar sin utgångspunkt i hörseln och det vi hör. Utifrån en litteraturstudie och egna reflektioner har ljuds betydelse och hur det påverkar oss i det dagliga livet undersökts. Syftet har varit att öka förståelsen för vad ljud betyder för vårt välbefinnande och hur vi som landskapsarkitekter kan ha ljudet i åtanke när vi gestaltar utemiljön. Ljud är mer än den fysiska ljudvågen. Det kan ge oss information om vår omgivning, spegla rörelser, underlätta orienterbarheten och vara en del av hur vi uppfattar rumslighet. Vi hör hela tiden, men lyssnar inte alltid medvetet.

Our purpose was to investigate the schools and the social welfare´s experiences of Roman children´s school situation in a Scanian town. We have done a qualitative investigation, interviewing 14 persons from both school and social welfare. Through the interviews we wanted to find the factors which influences the Roman pupils schooling and which efforts the professionals has to their disposition to influence these children´s school situation in a positive direction.The main result of our study is that the majority of the Romans is an isolated group, both in the Swedish school system and in the society. The Romans got access to the Swedish comprehensive school first in 1965, which implies that the Romans have a young school tradition. Most of the Roman pupils have a high absent, which is grounded in a complex of problems.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

This study is a statistical content analysis, of masters? theses written in 2005 at the Swedish School of Library and Information Studies in Borås. The relations between their epistemological discourses, theories, methods, themes and chosen alignment within the education, the so-called ?kollegium?/college, are examined. The results are put in relation to the concepts multidisciplinarity and interdisciplinarity to see what kind of discipline Library and Information Science (LIS) can be described as, on the basis of this material.

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

This study is a thorough comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.

The aim of this study is to widen our knowledge about the basic idea about having an open preschool for adopted children as understood by parents of adopted children and a preschool teacher. Sweden has a large number of international adoptions, in an international comparison among the highest numbers of adoptions per capita. Interviews were carried out with seven adoptive parents and one preschool teacher teaching at a special preschool for adopted children. It was found that adoptive parents had no particular problems with placing their children in an "ordinary" preschool. However, they choose to place the children in an open preschool solely for adopted children because of the possibility of sharing similar experiences as parents and children as well.

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.

Vi lever i en tid då människor är mer rörliga över landgränser än någonsin förr. Detta får till konsekvens att det blir allt vanligare att människor har kopplingar till flera länder på olika sätt. Det blir också vanligare att personer av olika nationaliteter och ursprung gifter sig och skaffar barn tillsammans med följden att det blir vanligare att familjer efter en separation har anknytning till flera stater.Denna uppsats undersöker hur olika internationella instrument försöker skydda barns rätt till kontakt med sina föräldrar när de bor i olika länder. Vidare diskuterar uppsatsen hur och under vilka omständigheter umgängesdomar som beslutats i en stat kan verkställas i en annan stat. I detta syfte undersöks flera internationella instrument, men fokus ligger på Bryssel IIa-förordningen, 1980 års Haagkonvention och 1996 års Haagkonvention.I uppsatsen konstateras att hur verkställigheten av en dom i Sverige sker beror på i vilken utländsk stat domen har utfärdats och det konstateras att de olika instrumenten är olika effektiva vad gäller att verkställa en umgängesdom.

This master?s thesis investigates how six Swedish public libraries integrate equality aspects in their user oriented activity. The theoretical starting point for the study is that Sweden is a part of a gender system characterized by gender separation and male superiority, as described by the Swedish historian Yvonne Hirdman and theories that argue that femininity and masculinity are social constructions. Another starting point is that the library sphere cannot be separated from the gender inequality in society. Since the library is part of a gender system that value individuals who are seen as males and separates men and women, some of the library users may be neglected.
