Naturvärden i en värmländsk bruksskog : en skogshistorisk studie av Åbengtshöjden/Bogranghöjden
In this study I have analysed the history of a forest belonging to Saxåhyttan in Värmland. The study area is 448 hectares and has been used by iron industry since the 16th century. A forest that has been used by man during at least 400 years should have few ecological values. This inventory however shows the opposite.
The aim of the study is to interpret the history of the forest in the area, i. e.
Hantering av småskalig elproduktion : Utveckling av modell för dokumentation och elkvalitetsberäkningar
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.
Tobaksvanor i tre idrottsklubbar - unga män 16 och 19 år
The use of tobacco is one of the largest health risks for human. Tobacco-users have an incrased risk of deterioration in their oral health. Individuals starts to use tobacco when they are young, often at the same time as they are going in an athletic sport club. It also seems that children are starting with tobacco habits when they are active in athletic sport clubs. The aim of this study was to examine and compare tobacco-habits of young men in and between three different athletic sport clubs.
Elevers förståelse av fotosyntesen och dess koppling till andra organismer
The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ã…ngerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ã…ngerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.
Tillväxt hos Husmossa (Hylocomium splendens) i boreal skog och växthus : effekter av ökad vattentillgång
Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.
Kartläggning av hörselnedsättningar, öronsjukdomar samt diagnostiseringsmöjligheter hos 1 ? 5 åriga barn
Ear disease and hearing loss in preschool children can be difficult to discover and diagnose. This paper investigates ear disease in 20 children controls from 1 to 5 years of age. The aim of the study was to map prevalence and incidence for ear disease, and prevalence of hearing loss in a group of children.Twenty children wide aged 1, 1½, 3 and 5 were included and investigated according to a set protocol with psychoacoustic tests, tympanometry, ear microscopy and a parental questionnaire. The majority of the children could be evaluated by age adequate psychoacoustic tests and otoscopy. Tympanometry was the investigation method that was most difficult to perform.
Konsten under jorden : En analys av Ulrik Samuelsons konst i Kungsträdgårdens tunnelbanestation
This study examines the work of art in the underground station Kungsträdgården in Stockholm and discusses the observers interpretation of the art in the station. When the artist Ulrik Samuelson got his commission to shape the station he was influenced by Marcel Duchamp and the concept art. Two themes were integrated in the work of art, the actual culture life and the palace called Makalös, which was situated just above the currant station, three hundred years ago. The station was built in two stages.The first part was opened in 1977 and the second part in 1987. Panofsky´s iconographic working method has been used in this essay.
Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans
This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.
Dynamisk styrketräning av M : Quadriceps femoris hos personer i övre medelåldern
AbstractElderly people are going to be a growing number in Europe. Between one third are going to be 60 years or older at 2025. For Sweden the situation is going to be similar. A reduced muscle function could lead to complications for the individual to perform daily tasks and will lead to a higher rate for falling and getting bone fractures. The positive sides are that for men and women there are a possibility for maintaining physical function and strength even in older years.
Kärlek, misshandel och trauma. En fallstudie om kvinnomisshandel och dess konsekvenser.
Male violence against women in close relations has in recent years received
increased attention, however, only identified as a problem in approximately 40
years. It is now a social problem that is constantly increasing, but the
identification of the phenomenon has been possible thanks to the research on
the subject. The purpose of this study is to, from a woman's own story,
identify psychological processes in connection with the assault. The aim is
also to confirm previous research on the phases of the abused go through until
decampment and identify possible consequences of violence against women. I also

situations while getting back to society.
Kontorsanställdas psykiska välmående i relation till deras fysiska aktivitetsnivå
Background: There have been doping usage as far back as as ancient Greece and around the early 1900s started the doping we have today. In 2008 it was 22,000 men aged 15-54 years old who had any kind of experience with doping in Sweden. The problem of doping use are all over the world and to overcome this problem, we need to work across borders.Objectives: The purpose of this study is to investigate whether there is any connection between the use of supplements and attitude to doping. The study is based on the questions: is there any connection between the use of supplements and positive attitude to doping? is there any connection between the use of supplements/doping substances and high training frequency? and is there different use of supplement/doping substances between girls and boys?Method: A survey in form of a cross-sectional study and a waiting room survey was conducted with 63 respondents of whom 57,1% were women.
Gränser och gränstillstånd : Möten med det övernaturliga i den naturmytiska balladen
This two years master?s thesis is about book circles for children, arranged by the public libraries in Sweden. The purpose is to gain knowledge about how children experience their participation in book circles, and how they experience their own reading. It focuses on children aged 10 to 12 years, and their leisure reading. The research questions are: What are the book circles? function for the participants? How and why do the children read? What kind of literature do they like? Do the children experience that their reading has developed through their participation in the book circles? What parts of the reading process do the book circles influence?The theoretical framework is threefold.
Undersökning & Utvinning av Smartphones : En djupgående analys av positionsdata
The ordinary phone of today is not the same as it was 10 years ago. We still use them tomake phone calls and to send text messages, but the ordinary phone of today has muchmore uses, it is essentially a computer. To put into context to 10 years ago, it is a verypowerful computer, capable of processing wide array of information and presenting it tothe user. Nearly every single device today has a wireless connection, which makes everyuser connectable and able to use online services and internet at any time and place.This gives the user the possibility to integrate his or hers everyday actions with socialmedia and different search functions. Being able to search the internet for persons,restaurants, public transportation and a lot more is very useful to most.
Ensam - i fantasin eller i verkligheten? : En jämförelse av det ensamma? barnet och dess verklighetsflykt samt av karaktärsroller i Astrid Lindgrens "Mio, min Mio" och "Bröderna Lejonhjärta"
 The english name of this essay is ?One man among many women?. This essay takes its starting point in the situation today with few male teachers in the earlier years of elementary school. I have decided to look at the small group of males that actually started the education to become teachers and why they did it when the profession as teacher today is low-paid, low status and is a profession with a large dominance of female teachers. I have chosen to write about this because of the importance for the children to meet both men and women as teachers in the early schoolyears.
Projektering av vindkraft i turbulensintensiva områden : med fallstudie för Wallenstams planerade park vid Skuggetorp
Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.
