This thesis analyses how a radiology department at the largest hospital in Sweden, Karolinska University Hospital, most profitably could expand its capacity for investigating cancer patients using magnetic resonance imaging (MRI). The queues today for patients waiting to be scanned are long, which delays the start of cancer treatments. Meanwhile the hospital has a budget deficit of half a billion SEK, which make any expansion hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these.

AbstractThe purpose with this study is to find out how pedagogues, who teach in the early years of primary school, motivate and stimulate all pupils so they want to read a lot of fiction. The research also includes finding out more about why the pedagogues work as they do. The research starts with a study of current literature which deals with how teachers should work with motivation and stimulation in school. To find out how the pedagogues work in school I have made qualitative interviews with four pedagogues who work in the early years of primary school. The result shows that all of the pedagogues motivate and stimulate pupils in similar ways.

The purpose of this Masters thesis is to accomplish an understanding for childrens librarians purchases of juvenile books. Two main questions are to be answered: - Which considerations do childrens librarians do when buying juvenile books and which goals and motives are behind their purchases? - What do childrens librarians think that their knowledge and competence consists of and how is that knowledge useful when buying juvenile books? To answer the questions qualitative interviews with five childrens librarians have been carried out. The material has been analyzed through a theoretical construction consisting of theories about collection development, book selection and quality judgments. The conception tacit knowledge silent knowledge from Michael Polanyi has also been used for interpretation.

Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..

The purpose of this master thesis is to investigate what the work situation of children's librarians looks like in the year 2000, after the changes in society which took place since the 1980's. Did the tasks of children's librarians change during the nineties, and if so, in what way and why have they changed? Which new knowledge needs emerged for children's librarians during the nineties, and what was the cause of these new needs? Finally I want to know which needs for professional development arose, and how these needs are fulfilled. The thesis is based on qualitative interviews with children's librarians, library managers, library consultants, one representative of the Swedish school of Library and Information Studies and one member of SAB's children and youth committee. The study reveals that the identity of children's librarianship is strongly associated with the stimulation of language and reading.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

Uppsala- och Stockholmsregionerna använder Mälaren och dess tillflöden som dricksvattenkällor. I Mälaren varierar halten organiskt kol från år till år och kan medföra problem såsom oönskad lukt, smak och färg vid dricksvattenrening. Det kan även vara problem med avseende på bildning av desinfektionsbiprodukter (DPB) och transport av toxiska ämnen med dricksvattnet. I takt med den globala uppvärmningen kan dessutom halten av organiskt kol i Mälarens ytvatten och dess tillflöden öka. Det medför att halten av organiskt material även skulle öka i vattenverkens råvatten och det skulle i sin tur uppstå svårigheter att hålla dagens gränsvärden.

Ovarian stimulation in assisted reproduction often leads to the production of a high number of oocytes. After fertilization of these oocytes, the resulting embryos can be cryopreserved for later use. Vitrification is a recently introduced method for cryostoring embryos, showing high survival rates for both cleavage stage embryos and blastocysts. Characteristic of vitrification are high concentrations of cryoprotectants and ultra fast freezing which makes the material glassily. A major concern with vitrification has been the direct contact of the cryo-solutions with liquid nitrogen.

Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.

The purpose of our thesis has been to study Social Workers view of children?s needs and how they work with children?s needs when they are orphaned because of HIV/Aids in South Africa. The question formulations we used to answer our purpose are:? What needs do the Social Workers consider the children to have?? How do the Social Workers work with children?s needs?We have a qualitative methodological approach in the thesis, where we have performed four interviews with four Social Workers on different organizations in and around Cape Town, South Africa. The presentation of the empirics is made as a summary with representative quotations, which we have interweaved with earlier research and theoretical conceptions.

The demand för Swedish pork meat is increasing every day. This leads to agricultural farming having to develop as an industry, with larger and more rationalised units to make the farming more effective and to raise the financial profit. The consequence of this is that it affects the animals when their surroundings become more industrial. The pig´s natural behaviour becomes restricted by the limitations of the facilities, which leads to them becoming understimulated. Helena Kummel, a teacher at Munkagård upper secondary school and also an educated animal inspector has developed a prototype that could possibly replace the pig´s natural rooting behaviour inside the barn. The porpuse of this report is to study "bökboxen" in the gilts´actual living enviroment, through qualitative- and quantitative analysis.

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

The increased competition in e-commerce puts pressure on e-businesses which makes it even more important to influence the visitors on their e-commerce sites. An often overlooked marketing tool is atmospherics. With the increased focus on e-commerce from both traditional and new e-businesses this marketing tool becomes even more relevant. The aim of this thesis is to investigate how the atmosphere on an e-commerce site influences the customers' thoughts, emotions and behaviors. We examine the effects the level of stimulus on a website has on the customer's emotions, attitudes, intentions, behaviors as well as the relationship between these variables.

De högpresterande eleverna i skolan har precis som alla andra elever ett behov av bekräftelse, stimulans och utmaningar. Syftet med denna studie är att belysa lärares syn på de duktiga eleverna i skolan. Studien kommer även att beröra lärarnas syn på sin egen kunskap, samt hur de arbetar för att stimulera dessa elever i skolan. Studien ger en översikt av tidigare forskning i ämnet. För att uppnå syftet med studien så genomfördes kvalitativa intervjuer med fem grundskollärare på två olika skolor.
