Rökgaskondensering och skrubber till vedeldade villapannor :
This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied.
The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.
?För mig var det nödvändigt att bli förbannad? : Om ilskan som kraft för våldsutsatta kvinnor

Identifikation av icke-representativa svar i fra?geunderso?kningar genom detektion av multivariata avvikare
To United Minds, large-scale surveys are an important offering to clients, not least the public opinion poll Va?ljarbarometern. A risk associated with surveys is satisficing ? sub-optimal response behaviour impairing the possibility of correctly describing the sampled population through its results. The purpose of this study is to ? through the use of multivariate outlier detection methods - identify those observations assumed to be non-representative of the population.

Optimalt råvarulager för biobränsleföretaget :
This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant.
Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.
Potentialen för alternativ användning av processgaser vid
SSAB i Luleå
Syftet med detta arbete är att studera möjligheterna att nyttja de biprodukter som bildas vid integrerad ståltillverkning hos SSAB Tunnplåt i Luleå. Biprodukterna i detta fall är de energirika processgaser som skapas från koksningsprocessen, masugnsprocessen samt LD-processen. Detta arbete har koncentrerats på att titta på de förutsättningar som finns för att separera ut metanet som finns i koksgasen för vidare användning internt inom SSAB-koncernen. Påpekas bör att en stor del av processgaserna som bildas vid koksverk, masugn och LD redan återanvänds internt på SSAB Tunnplåt AB som bränsle i flertalet processer. Överskottet av dessa gaser blandas och används sedan bland annat av det närliggande värmekraftverket, Luleå Kraft AB (LUKAB) och Nordkalk.
Den perfekta informationsspridaren? En komparativ studie av tre organisationers intranätanvändning
This is a comparative study of the use of intranet in three organizations. The organizations are one help organization, one hospital and one business company. The intranet is a relatively new medium and it might still not have been accepted by all potential users, which is a waste of resources both for the individual employee and for the overall organization. It is therefore necessary to investigate if there are any differences between organizations concerning the needs of intranets. Our purpose with this study was to deepen the understanding of the use of intranets as a channel of organizational communication and thereby acknowledge the users´ needs and opinions of the intranet.
Vilken relation har fosterföräldrar till sina fosterbarn. : En kvalitativ studie av fosterföräldrarnas upplevelse av fosterföräldrauppdraget.
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.
Enantioselektiv HPLC-analys med kirala stationärfaser bestående av makrocykliska glykopeptider och polysackarider
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.
STRESS med stora bokstäver bland små och stora människor
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.
"Klänningen som får en andra chans" : klädkonstruktion av återbruksmaterial
This report presents a bachelor thesis by Erika Gustrén aimed to increase people?s interest for recycling and reusing by create new products of things that already exist in most people?s homes in the materials textile, plastic and paper. That would be a modern and innovative way to contribute to a better environment.The goal with this project was to create three cocktail dresses made of the same pattern and design and with the three chosen materials. The project did not have its base at a company, therefore an external mentor was chosen to help and support during the development of the project. My mentor was Kerstin Boulogner who is a fashion designer and one of the members of GKF (Gotländska Konsthantverkare och Formgivare) in Visby.The project began with an analysis of the chosen materials; textile, plastic and paper.
Integration, separation och allt där emellan - En studie om romska barns skolsituation
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.
Disciplinen vi delar - En innehållsanalys av magisteruppsatser vid Bibliotekshögskolan i Borås
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.
Hur fungerar indexering av skönlitteratur? En konsistensundersökning
The aim of this master thesis is to find out how indexing of fiction works. I look at the consistency when users? choices of index words are compared with each other and I also compare users? choices to the current indexing made by libraries. I examine the subject heading list, Att indexera skönlitteratur, to find out how well it works in this particular context. The investigation included seven users who, in three steps, are creating a subject heading index of the Swedish novel Klippdockan by Cecilia Dahlheim.
Hållbar stadsutveckling genom förnyelse : med utgångspunkt i miljonprogrammets Gårdsten
In Sweden and in the rest of the world we face the problem how to create a sustainable development. At the same time the Swedish million program, a housing program made in the 1960:s and 1970:s, is facing a renewal due to lack of maintenance during many years.
An attempt to join these two interests has been made in the residential area of Gårdsten north of Gothenburg. This paper is a case study to review the project and its approach to the sustainability concept. The purpose is to spread knowledge about the problems that can arise. By studying documentation about the reconstruction I have analyzed the approach that has been used.
The housing company?s starting point was user participation and an intention to make the changes visible.
