The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.

Pyometra (chronic purulent uterine inflammation) is a common disease in middle-aged and older intact bitches. The disease most frequently occurs in metoestrus and previous research studies have shown that both hormones and bacteria are involved in the development of the disease. Analysis of the blood levels of prostaglandin metabolite 15-keto-13,14-dihydro-PGF2? (PG-metabolite) has previously been shown to be clinically useful in the differentiation of canine uterine diseases such as pyometra and mucometra. The PG-metabolite concentration has also been correlated to severity in pyometra as determined by hospitalisation length. The purpose of the present study was to investigate if blood levels of PG-metabolite can differentiate uterine diseases such as pyometra from other diseases in female dogs.

Syftet med denna undersökning var att studera om pedagogiskt drama kunde vara en metod för att utveckla elevernas kommunikation och relationer för att stärka arbetet med värdegrunden. Undersökningen och utförandet av dramapass hade sin grund i tidigare forskning kring pedagogiskt drama, värdegrunden, kommunikation och gruppdynamik. Vi valde observation som metod för att studera de dramapass som vi utförde med vår undersökningsgrupp. Dessa observationer har vi sammanställt och analyserat med våra fokusområden som grund. Dessa fokusområden är kommunikation, relationer samt olikheter. Vårt resultat av analyserna är att utvecklingen av elevernas kommunikation och relationer är avgörande för att stärka arbetet med värdegrunden.

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

This article presents a retrospective case study combined with a review of the current literature concerning canine gestational diabetes. A total of 14 cases have been collected from six different clinics in Sweden. There are few previously published reports on canine gestational diabetes. Gestational diabetes is a disease that rarely occurs in pregnant bitches. The condition is due to the rise of progesterone that occurs during the estrus cycle.

Osteoartrit (OA) är den vanligaste orsaken till för tidig pension av tävlingshästar och är den sjukdom som står för den enskilt största ekonomiska förlusten inom hästnäringen. Diagnostiken är svår i ett tidigt skede vilket gör att man vill hitta bra markörer och inflammationsmediatorer som kan användas för att snabbt ställa rätt diagnos samt sätta in lämplig behandling. Sedan början av 2000-talet har man i prekliniska studier på gnagare och människor tittat på den pro-inflammatoriska cytokinen high mobility group box protein-1 (HMGB-1) och dess inblandning i inflammationen vid artrit. De senaste åren har det även kommit studier på häst. Det här arbetet går igenom resultatet av dessa studier för att kunna diskutera vilken roll HMGB-1 spelar vid OA, dess lämplighet som markör för sjukdomen och huruvida en inhibering av HMGB-1 skulle kunna användas som en framtida behandlingsmetod. HMGB-1 är ett litet intracellulärt protein som finns i nästan alla celler hos vertebrater, bakterier, växter samt jäst.

The present work has been implemented as a literature study aimed to investigate the prevalence, possibly causes and consequences of an eating disorder. In today's modern society individuals are living with a constant reminder from the media about how a person should look and act to blend into the social norms and expectations of the modern society. This literature review has been analysed on the basis of concepts such as identity, gender identity and gender. In addition previous research has been analysed in terms of themes, history, possible causes/risk factors, media, body image and control, depression, shame and guilt as well as culture. The above themes were analysed on the basis of behaviouristic theory and role theory.

Half of Sweden's productive forest land is owned by individual forest owners. Research studies show that forest owners have more objectives with their forest than a high net present value, and that the suggestions of the forest management plans doesn?t always correspond to the forest owners? objectives. Through a qualitative study we conducted a discussion about objectives at stand level with the aim of making a more specific formulation of the forest owners? objectives. We asked about the forest owners' objectives at stand level, what forest management they conduct in order to achieve the objectives and how this management affects the net present value of the property. Based on the results of the interviews, we analyzed what kind of factors decide where the objectives place themselves in the landscape and if the objectives at stand level are consistent with the overall objectives for the property. Many forest owners questioned the idea of talking about objectives at stand level, and they didn?t always have their objectives clearly defined.

The specified purpose was, based on gender, age and type of employment, study the employees motivation to participate in health projects and their reason to maintain exercise habits after the termination of the health projects. Exercise frequency was studied in relation to the other background variables. A revised version of the questionnaire Motivation for Maintenance of Exercise Habits (Josefsson, 2005) was distributed at Albany International, Halmstad. The most frequent cause to exercise was ?enhance my condition?.

This masters degree is a study of factors of success in a drug preventions work of change and model or method which could facilitate this work. The target group, which is in focus in this survey, is alcohol- and drug coordinators, also called prevention coordinators who?s main task is to develop and coordinate the preventive work in the alcohol and drugs area. My method of investigation is a combination of literature studies and a quantitative poll study with the target group, alcohol and drug presenters?, in Sweden.

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.

When are aerial bombing strategies effective in coercing target states? According to the recent research debate there is a consensus that denial strategies may be an effective instrument for coercing states to change their politics. This study is based on Belkin?s theory which argues that the effectiveness of denial strategies may depend in part on the domestic legitimacy of the target states? regimes. From a political standpoint, aerial denial effectiveness can be considered more likely to coerce when political leaders of target states lack domestic legitimacy rather than when they are legitimate.   The purpose of this study is to contribute an explanation of a condition where denial strategies are more likely to succeed.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Even though the American author H.P. Lovecraft (1890-1937) has been praised as one of the most influential writers of horror literature in the 20th century, his style of writing has occasionally been criticized. Lovecraft was using a writing style based on strict scientific language, where the human condition and existence are irrelevant in the narrative. This includes less focus on character development and more on the importance of atmosphere and environments. I am presenting narratological analyzes of what is often considered to be three of Lovecraft?s ?greatest works?: ?The Call of Cthulhu?, At the Mountains of Madness, and ?The Shadow over Innsmouth.? These analyzes are used to highlight Lovecraft?s science-oriented language and narratological techniques, with the focus of studying what methods Lovecraft was using to give his works and his readers a sense of dread, hopelessness, and an alien atmosphere.

At ABB LV Motors in Västerås the shaft is assembled into the rotor with a shrink fit. After athorough investigation of the assembly method, several factors that make the insertion of theshaft more difficult has been discovered. Some affect the assembly directly while others onlyhave an indirect influence. The investigation has shown that the radial play between the shaftsouter radius and the rotors inner radius might be too small which could lead to anunsuccessful assembly. For the larger rotors, the condition is the opposite, and the rotor mightmove compared to the shaft direct after the assembly when the rotor still is warm.
