Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.

This study aims to explore parents and treatment personnels experiences of the Marte meo methodat a family treatment home. Three retrospective interviews were made with parents whoexperienced Marte meo treatment, as well as four interviews with treatment personnel. The purposeof the Marte meo method is to develop the interaction between parent and child. Previous resultsfrom studies show that treatment with the Marte meo method could provide positive effects to theparent child relationship. The results in this study have been analyzed by using parts of attachmenttheory, the salutogenic perspective and the term intersubjectivity.

The purpose with our essay was to examine what favourable factors there are for women to get out of drug abuse and from a gender aspect interpret how these factors are used in the treatment of female drug-addicts, regarded from the treatment personnel view. The questions we have focused on are: What are the favourable factors for women in the way out of the addiction. How can the use of favourable factors be interpreted from a gender aspect. In what way is the knowledge about these favourable factors used in the drug abuse treatment.To fulfil the purpose whit our examination and to get answers to our questions we performed an explorative examination and applied a qualitative method in the form of a half structured interview with five persons.The main features of the results in our examination were that unisexual treatment, the group and the friendship between women, children and pregnancy and professional and private social network were considered as the favourable factors for the women out of their addiction. Certain factors were used in the treatment as a way to socialize or resocialize the female drug-addicts to predominant social models of how a woman should be like..

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

The purpose with this study was to investigate the client?s experience of Marte meo treatment and the procedure in the treatment from a responses and relational perspective, since the treatment occur within the social service frame. The theoretical framework consists of some central concepts. The concepts are experience of treatment, responses and relational perspective. The analysis of the empirical material has been carried out with the help of the concepts and earlier research.The method consisted of qualitative, semi-structured interviews with six informants.

In this study have I examined how treatment of girls with neuropsychological impairments is functioning? I have looked at the theories and methods of treatment on the base of the care program and how it is put into practice. In addition I have interviewed four girls who have undergone the treatment program.To gain perspective on institutional care as a social phenomenon, I have tried to give a brief historical retrospect in which particular care for women are described. I am also affecting certain gender aspects of institutional care. I have also tried to make a brief account of current research on the treatment.The study is a qualitative study in which I am apart from literature studies used participant observation in depth interviews as a method.My results indicate that a well structured treatment with CBT approach can work well to achieve lasting behavioural changes in students..

The main purpose of this thesis was to take part of girl?s descriptions and experiences of their treatment for deliberate self-harm and to investigate whether they still experience effects of the treatment today. Our main research questions where; how do the girls describe their experiences of the treatment method, do the girls describe that they still experience any effects of the treatment, and finally how do the girls look back on their treatment today? In order to answer these questions, we carried out eight qualitative telephone interviews with girls that had undergone treatment in a specific treatment centre. We chose to analyze the material from the salutogenic theory and the concepts of SOC (sense of coherence) and with a hermeneutic approach.

People with severe mental illness and co-occurring substance abuse are an especially vulnerable group in society as health care for those is shared between municipality and county council. There is an associated health need of this target group so the interaction of the social services and the psychiatric care is of great importance. However, there are shortcomings in this interaction with results in that people with dual diagnosis do not always receive adequate care. Diverse knowledge and explanatory models may create problems for the interaction as they include different ways to define, understand, explain and deal with a problem. The purpose of this study was to examine how the interaction between the social service addiction treatment and the psychiatric care is, concerning people with dual diagnosis, focusing on how their respective knowledge and explanatory models affect the interaction.

Bipolar disorder is a chronic affective disorder, characterized by episodes of mania and depression. Previous studies have shown beneficial results for CBT in conjunction with pharmacotherapy over pharmacological treatment alone. The aim of the present study was to evaluate a CBT treatment in group for patients with bipolar disorder, run by Norrlands universitetssjukhus. The treatment group consisted of pharmacologically stabilized patients (n=12) who received group CBT. They were compared to a control group (n=5) who received pharmacological treatment only.

The field of work and employment is constantly undergoing changes. In order to help organizations to adjust to new conditions, different models for organizing have been developed. Many of these models are spread worldwide, due to the need for organizations to meet demands of flexibility and efficiency. In this study, a small number of models, which contains solutions of how to organize work in Human Resources, have been selected. The author and scientist Dave Ulrich, who has had a large influence on the development of the work in Human Resources, originally founded these models.The aim of this study was to examine how these models were functioning, in reference to the different departments of Human Resources labor within the township of Uppsala.

Computers together with Internet have been growing enormously, during the last decade and the area of information technology has been growing in the same speed. As long as the surrounding environment evolves, the business models must within the IT-area, keep the same pace. So, how do business corporations handle this change to attract customers? How do the dominant business models look like? In many cases, they are apparently much the same. But what differences can we see and what areas can be improved? We have showed that the IT area isn?t just one, it consist of several segments.

On children born with a complete cleft lip and palate (CLP) the repair of the alveolar ridge doesn´t take place before the children are about ten years old. This results in that they have a residual cleft in the alveolar ridge during their early childhood. This residual cleft, and the oronasal fistulas that may appear after the repair of the hard palate, can result in a negative influence on the speech of the children. Thereby it may be necessary with cover for examplewith a palatal plate or an obturator. At the Department of Orthodontics, at Linköping University Hospital, Sweden, some of the children with CLP undergo treatment with sustained palatal fistula obturation in order to cover fistulas or residual clefts.

Background: The valuation of Biotechnology companies is difficult in many ways. Patent and human capital are hard to value and also there is a great uncertainty about the success of the compaines research programs. Are traditional valuation models really useful when it comes to research companies or do they result in false values of the companies? Purpose: To study what values different valuation models gives biotechnology companies and how they correspond to the market value. Method:We have studied financial litterature och found the most common used models today.
