Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer
Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.
"Här hymlar vi inte om sånt" : Synen på arbete och klass i Stig Sjödins Sotfragment och Jenny Wrangborgs Kallskänken
The purpose of this thesis is to examine how the public libraries work towards SFI (Swedish For Immigrants) based on the views of the overseeing librarians. To study this we have asked the following research questions:What distinguishes the public libraries? work towards SFI according to the responsible librarians? What distinguishes the communication between SFI teachers and the librarians according to the responsible librarians? What opinions are held by the librarians in regards to their work with SFI?We have used a semi structured interview method with seven librarians in charge of the activities with SFI at small and medium sized public libraries in a rural area of Sweden. The theoretical framework is composed of Marianne Andersson and Dorte Skot-Hansen?s model for analysis of the local public library profile and the authors? definition of collaboration.
Cisterciensklostrens odlingar i Sverige under medeltiden
The aim of this paperisto find out which plants the Cistercian monks might have cultivated in Sweden during the Middle Ages and which types of plants it would have been practical to grow inside or outside of the Cistercian monastery precinct. Archaeologicaland archaeobotanical studies have been consulted to find out which plants were available in Sweden during the Middle Ages. Examples, mainly from Scandinavia, but also from the continent, are used to show that the monasteries were large institutionsthat had to feed a large number of people and that there would not have been enough space to cultivate everything needed within the monastery precinct.Secondary sources have in the main been used to gather this information, except in the case of the Swedish monastery of Nydala where F-Topo, a database developed by the County Museum of Jönköping,has been used to analyse the amount of land and the types of properties owned by the monastery.The conclusion is that for practical reasons the monks would have cultivated plants that needed to be close at hand, that were rare or delicate, that could not be stored for long periods and that were used in small quantities within the monastery precinct. This would include medicinal plants, herbs for cooking and some vegetables like lettuce, spinach,and similar,that do not keep well. Most other items, grains, cabbages, root vegetables, peas and beans could equally well be cultivated outside the walls.
Passivhus med prefabelement : En jämförelse mellan en platstillverkad konstruktion och prefabelement från Masonite Lättelement AB
This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..
Arbetsmiljöarbete enligt OHSAS 18001 : En inledande undersökning
There are regulations in sweden that require organizations to manage occupational, health and safetey (OH&S) issues in a systematic way. The contents of the management system vary depending of the activity of the specific organisation. An accurate management system is crucial in order to assure that rules and regulations are fullfilled. The OHSAS 18001 standard covering OH&S management is intended to provide organizations with the elements of an efficient OH&S management system. The work with this thesis was done at Swemat AB in Härnösand wich is a mechanical industry. In the thesis, the requirements of the OHSAS standard are compared with the current management system.

Skadliga nollflödespunkter i Fortum Värmes fjärrvärmenät i Stockholm : En analys av dess förekomst och effekter
When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.
Svenska upplevelser av spice : En kvalitativ studie av upplevelser av spice på ett svenskt internet forum
A film can attract all kinds of emotions and moods of the audience through its audiovisual communications and cinematic expression, in which music plays a significant role in both understanding and interpretation of film content.It is interesting to explore the musical significance and the emotional aspect of the film out of a media and communications perspective and visual communications perspective because it?s a subject that belongs to the communications of scientific discipline as film is a media text which is working both as communicative and as audio-visual medium with its expressive aspects.The purpose of this bachelor?s paper is to increase and deepen the understanding of music's function and significant role in context with its reinforcing sense of visual expression in film. More specifically, it aims to explore the musical value of the expressive aspect of the media text in form of film musical Les Misérables (2012), which has been transmedialised from the novel of the same name, referring to the sound, music and song in relation to the film's visual expression.The research questions are at the core of the essay study: "how is music used to reinforce the cinematic visual expression?" and "how can music signify the narrative and highlight the emotional aspect of the film?" The theoretical framework is based on some of the key scholars assumptions such as Michel Chion (1994) and Claudia Gorbman (1987), who share the same theoretical views that the soundtrack seems powerful when it expresses its participation in a scene?s emotional moods as the music follows the scene?s rhythm, the image?s flow and contributes emotional and musical codes of emotions and expressions. According to Chion sound and image interact together to tell a story where sound enrich the image with expressive and informative values.
