Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.

The power of the meeting is a qualitative study primarily examining how homeless men and women and social workers experience the meeting between them. The homeless are the more vulnerable part in these meetings so their experience of these meetings is my focus in this study. I have in this paper also examined and analyzed how and whether homeless women and men tends to be treated and ad-dressed differently with basis on their gender. The main results I have found is that the homeless but also social welfare officers actually feel that there is com-municative problems when the parts meet and cooperates which often results in conflicts and lack of trust. I have chosen to highlight a number of factors that have been claimed as the main reasons for the experience of a poor meeting.

Our aim was to explore employees' experiences of exposure to violence, threats of violence as well as their experiences of encountering victims of violence and to relate their experiences to Sense of coherence (SOC) and Maslach's burnout inventory (MBI).We sent out a questionnaire to employees at three different workplaces. Our questionnaire included previously validated SOC and MBI questionnaires as well as six additional questions regarding violence. We sought to explore the relationships between experience of exposure to violence and encounters of victims of violence and SOC and MBI. We found that employees with a higher level of SOC exposed to violence or threats felt a higher level of security. In encountering victims of violence we found that employees with a lower level of SOC more frequently experienced indifference, fear and anger.

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.

By tradition horses are weaned at an age of 5-6 months. This study illuminates weaned foals misdirected suckling behaviour, which means that they try to suckle another foal. Since no information about this issue is presented, we decided to perform a behaviour study on weaned foals. The misdirected suckling behaviour was studied on a group with 7 foals, with both fillies and colts. In the group the weaning age varied between 147 days and 215 days, and the first time we observed them, they had been separated from the mares for 12 days.

Lerbodaälven is a river in the municipality of Kil which, due to high phosphorus content is not meeting the requirements for good ecological status according to the Water Framework Directive. The purpose of this report is to investigate the causes for the high content of phosphorus that has been measured in Lerbodaälven between 1995-2010. Four questions will be answered in this report. 1. Does the sewage treatment work affect the phosphorus level in Lerbodaälven? The result from the time series analysis shows that the sewage treatment works have a small impact on the phosphorus level in Lerbodaälven.

AbstractThe purpose of this essay was to study the parental education for adoptive parents. It´s provided by law since 1/1-2005 that parents have to participate in this education-program before they adopt. We wanted to look at what caused the change and made the education compulsory and to find out where the initiative came from, what purpose the education is supposed to fulfil, if it can facilitate for adopted children during their growth and whether the parental education can support the idea of what is best for a certain child always has to come first, according to the UN convention on the Rights of the child and the Haag-convention.The study was based on eight qualitative interviews, four with social workers, three with representatives of adoption-organisations and one with a representative of the public authority of international adoption (MIA). The conclusions of our study are that there is a risk that the education can not fulfil its purpose to prepare parents for their task, that it looses the idea of what´s best for the child and focuses on the parent instead. It seems to be more of a try out to not violate conventions signed and thereby fulfil a symbolic purpose..

The purpose of this essay has been to investigate how newly arrived asylum seekers experience their first month in Sweden. The focus has been on the introduction week that is given within the first month of their arrival, although the study aims to treat the reception that is given in general. This is important because the refugees are in a sensitive state, leaving their country for different reasons, and coming to a new place wich they know nothing or little about. The questions at issue has been the following; * What are the refugees´ views of the information and the treatment they´ve been given during their first month in Sweden? * Which are the possible reasons for the refugees experiencing the reception the way they do? The methods I´ve used have been observation studies during the introduction week, plus interviews with participants of this introduction.

Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.

The purpose of this paper is to examine what problems cabbage growers have with the Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become a larger problem for cabbage growers in several countries in Europe as well as in Sweden. In Canada the problems are so severe that the midge is classified as a quarantine pest and therefore certain rules have to be followed. I have collected facts of the biology, host plants and reproduction of the Swede Midge, as well as the growers experiences and the occurrence of the midge in Canada, Europe and Sweden. The Swede Midge is hard to control because of its short life cycle and the larvae are protected between the heartleaves of the plant. When the larva feeds on the growth point the plant becomes distorted, in some cases several heads develop or none at all. When the midge infests spring rape its flower buds become undeveloped and rosette like.

The terror attack in New York year 2001 was a turning point in international politics. New policies were reformed in both USA and EU to secure their citizens from terrorism. The power of the institutions has developed and the question is; how does the new security policy affect people?s freedom? Is it the agencies new policies that are restricting the freedom or the actions of a terrorist? The purpose of this study is to examine if the security policies in USA and EU are protecting their citizen?s freedom. Many individuals are not aware of how much the security policies are affecting their lives.

The purpose of the study is to see differences and development of two institutions for social care (work science) in two countries - the University of Lodz, Polen, and the University of Lund, Sweden.The central question is, if there is any convergence between these Institutions for Social care.The method has been to use both earlier research and to have two interviews. I did interviews with two professors working at two Universities, one with professor Ewa Marynowicz-Hetka at Lodz University and the other with professor Hans Swärd at the University of Lund. I started to study relevant literature and took part of secondary material in both countries.The main result of this study is that some convergence tendencies between those two trainings exist. All of them have connection with international cooperation. There are also same forces that stopped those tendencies; one of them is tradition on institutions..

The purpose of this essay was to see how the construction of elderly immigrants as a problem in healthcare and elderly care has been described in the relevant literature. In the course of doing so I tried to answer the following questions; What is said to be the expected problems or difficulties in work with eldely immigrants? How are the expected members of the problemgroup defined and identified? Whos perspective dominates the description of the problem, the users or the investigators? These questions were hard to answer and I had to conclude that the problem was not clearly defined; there was only an assumption of a problem. This, however, has not been a hindrance in the category of elderly immigrants being claimed to be a group with problems that need research and further investigation. The dominating perspective is that of the investigators as they are the ones who define and identify who is a part of the problemgroup..

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.
