AbstractThis Master?s thesis analyses the dynamics of the medieval counterweight lever engine, ortrebuchet, a type of mechanical artillery. The purpose is to study the differences between different types of these machines, and see if computer simulations can be used to validate preserved advice on construction. Simulations include machines with a fixed counterweight, a hinged counterweight and a combination of both counterweights.Due to the almost complete lack of archaeological finds and insufficient historical source material there are still, after more than a century of research, many unanswered questions concerning the design and performance of these machines.The present study is based on an analysis by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used.

The sludgebark and to a certain extent the bark were until a decade ago waste products without any economic value that were thrown away. A number of environmental laws and increcing energy prices have improved the prerequisites for increasing the use of these materials. At Seskarö sawmill they burn the sludgebark and a great deal of the bark in the sawmill furnace. The sludgebark has a number of disadvantages compared to bark during burning. The sludgebark is often wet which means the energy net from burning often gets low.

This is a qualitative study about unaccompanied refugee?s support that they can get from Social Services and Migration Board. It?s a survey that is made in Skellefteå Kommun by interviewing four professional workers, two at the Social Services and two at the Migration Board. The questions in this study deals with the social support and how age may affect this support.

This thesis work resulted in a template for how the thermal spray process can be controlled through robot programs. The robots today and their programs need to be replaced, therefore a new structure which can be matched with the new robot systems is needed. The work is limited to only concern structured programming on the new robots on Thermal Spray Centre (TC) with the programming language Rapid. The basic data for the program was retrieved from interviews with concerned personnel at TC, from studies on process parameters for thermal spray and from existing specifications at Volvo Aero Corporation (VAC). The thesis work briefly describes the process thermal spray and the four methods used at VAC.

The overall aim of the study was to give an insight into the life of a girl attending a program for preparation for further studies. More explicitly it is the aim of this study to examine what line the girls take to and how they experience support in school and if the offered support is adjusted to the needs of the girls?.To capture the complexity of the girls? experiences a world view approach was used. To be able to take part of the girls? experiences, a qualitative survey method was chosen, built upon individual half structured interviews with six girls attending the last year of upper secondary school.

Bioinformatics is an interdisciplinary scientific subject which connects biology, biomedicine and information science. Bioinformatics generates new biological knowledge by using computer methods and biological databases and can thereby play an important role for the understanding of diseases and be used for development of new medicines. The appearance of bioinformatics has thereby had a big impact on biomedical research.In this study, I have examined bioscientists' use of bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and their needs of support concerning these resources. I have also examined which support the scientific libraries offer their users concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and have compared it with the needs the libraries think that the users have and the needs the users state that they have.The results from the study show that there is a wish for library support concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools. The wishes of the respondents are in contrast to the libraries' view about bioscientists interest concerning bioinformatic databases/web sites and bioinformatic tools.

The purpose of this study is to find whether there is any truth in the thesis that adopted children from abroad is in greater need of special support, in particular regarding factors that might inhibit the language development that may cause language problems.To achieve knowledge for this study, the methods have been to seek and analyze literature that discusses theories about language development and language socialization. To understand if theory and reality is cohesive, two interviews was conducted with special teachers that have had experiences teaching adopted children, analyzes of the results contra literature has been somewhat important and necessary. To ensure the reliability the interviews was recorded on tape and later transcribed.The results from literature studies indicates that adopted children are more likely to be in need of special support in school due to factors concerning, among other things, adaptation difficulties, language progress and identity. Overall, language progress is depended on children?s total progress that includes physical, emotional and psychological condition.

ABSTRACTBackground: Children and adolescents growing up in families where parents have serious problems are exposed to an increased risk of developing poor mental or physical health themselves. In a support group work they can meet other children in the same situation, receive help and support to process their emotions and manage their everyday life.Aim: To investigate if support group work at Trappan can reduce the psychological problems load and increase the experience of life quality, hopefulness and optimism in children and adolescents growing up in families where either addiction or mental illness occur in one of the parents. The purpose was also to investigate if there was any difference between these both child groups regarding psychological problems load, experience of life quality, hopefulness and optimism before and after support group participation.Method: Questionnaire study on children and adolescents of parents with addiction or mental illness. The children participated in support group work at Trappan. The measuring?s were conducted before and after support group participation.Results: In both groups an increased life quality in connection to finished support group participation was observed.

Every year a great amount of unaccompanied children flee their homelands without their parents or guardians. This means a journey filled with danger and difficulties. The difficulties don?t only exist during the road ahead but also when the children arrive to the new country. Even if Sweden?s work in receiving refugees is one of the best in the world, it still exist problems.

We have chosen to focus on the meaning of long-term income support dependency regarding health, goal setting and motivation for the recipient of economical aid. We have chosen to use semi structurized interviews to achieve our goal of reaching the clients experience of long-term income support dependency. The study consists of interviews of six clients whose answers have been analyzed through appliance of Kielhofner´s Model of human occupation, Scheff´s Shame in self and society.   Our results show regarding, 1) the factor health that long-term income support dependency may elevate the risk of illness and less experienced options of possibilities to act. 2) regarding the factor goal setting, that goals may be inefficiently used during social work with long-term income support dependent clients and may result in a disorganized relationship between client and social worker in the sense of making the parties pull in opposite direction. 3) regarding the factor motivation, that long-term income support dependency and the living with the emotion of shame elevates the risk of maintaining a negative image of oneself that limits the willpower to assimilate new knowledge and/or skills.

Most studies on parenthood and learning difficulties focus on mother and child, and very little is know about fathers with learning difficulties. Moreover, people with learning difficulties are rarely asked to tell their own narratives. The aim of the current study is to identify the role of the father in families where one or both of the parents have learning difficulties. Laws and regulations concerning the rights of people with learning difficulties in Sweden are accounted for and the he social support system for all parents in Sweden are described .The empirical study is a qualitative phenomenological interview study, inspired by narrative traditions, and describes how fathers with learning difficulties experience these support systems. The main data are two life stories of fathers with learning difficulties and one observation in a family.The findings suggest that although Sweden has a highly regarded disability policy and social support system, and even though fathers with learning difficulties are assured equal rights as members of the society and as parents by the Act of Human Rights, they are not treated equal but still faces structural inequalities.

There are many kinds of joint operations and combinations of combined arms. This thesis puts its focus on Close Air Support, CAS. Throughout history there have been several cases of success, regarding these kinds of operations, but also failure. Much can be taught from organizational behaviour studies, applied on these military organisations in their cooperation with each other. The purpose of this thesis is to analyze the cooperation between the Swedish army and air force to determine the functionality of their process.

The purpose of the study is to find out how some teachers in Kenya reason about children in need of special support. To undertake the study the following question are used:How do some teachers in Kenya reason about children in need of special support?The study has been made with qualitative interviews in Kenya. A total of four teachers at primary school level have been interviewed. The decision to do qualitative interviews is made by the opportunity to get as comprehensive answers as possible from the respondents' reason about children in need of special support.Three different kinds of special education perspectives have been used in this study.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
