Utveckling av golvlucka för hoppgropssystem i kommunal idrottshall
In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.
Sexualvanor och preventivmedelsanvändning hos svenska gymnasieelever
The aim of this study was to examine sexual behavior, contraceptive use, self-rated health, lifestyle factors and the prevalence of HPV vaccination among last year high school students. The study was a quantitative cross-sectional study which was a substudy of the longitudinal study " Pornography, Youth and Health". Results showed that the majority of students had had sexual intercourse (75 %, n=524) and both performed (67 %, n=479) and received oralsex (70 %, n=498). Forty percent (n=282) of the students had had one night stand, a quarter (n=159) anal sex and 29 (n=202) percent sex with a friend. The contraceptive use increased from the first to the last intercourse while the use of condoms decreased.
Den kvantandliga diskursen : En undersökning om nyandlighetens möte med kvantfysiken
This paper aims to describe and elaborate on a recent discursive change within the new-age movement. Since the seventies and the publishing of speculative popular science books like The Tao of Physics by Fritjof Capra and The self-aware universe by Amit Goswami, the idea that quantum physics resonates with spirituality has become the topic of hundreds of books and movies.The quantum-spiritual discourse has three distinct ways to approach quantum physics in its discussion on spirituality: The parallelistic approach which emphasizes the similarities between eastern philosophies and modern physics, the monistic-idealistic approach which tells us that mind is the foundation of matter and the scientific spiritual approach which tries to explain spiritual claims scientifically. In the quantum-spiritual discourse, quantum physical phenomena (e.g. non-locality and entanglement) are being called upon to validate metaphysical statements. The primary assumption of the discourse is that the shift of paradigm due to the establishment of modern physics also is a shift of paradigm of spirituality.With the object to examine the common claims made in the discourse, cross-references between spiritual arguments and facts of quantum physics are being made.
Energikartläggning av fastigheten Vägaren 24 i Stockholm: Åtgärdsförslag för energi- och kostnadsbesparing.
SammanfattningDet här projektet behandlar området Additiv Tillverkning (AM) för metalliska material och undersöker om det är lämpligt att använda vid produktion inom flygindustrin. AM är en relativt ny tillverkningsmetod där föremål byggs upp lager för lager direkt ifrån en datormodell. Teknikområdet tillåter i många fall större konstruktionsfriheter som möjliggör tillverkning av mer viktoptimerade och funktionella artiklar. Andra fördelar är materialbesparing och kortare ledtider vilket har ett stort ekonomiskt värde.En omfattande litteraturstudie har gjorts för att utvärdera alla tekniker som finns på marknaden och karakterisera vad som skiljer de olika processerna. Även maskiners prestanda och kvalité på tillverkat material utvärderas, och för varje teknik listas möjligheter och begränsningar.

Method: The study was an observational study with a cross-sectional design and group comparisons, conducted as a survey. The sample constituted of 60 employed nurses.
En effektivare källsortering för bättre materialutnyttjande - en behovsanalys
The waste fractions offered to households in Sweden differ depending on where you live. The responsibility for the waste are grounded by the Swedish law where the municipality are responsible for the collection of household waste and FTI are responsible for collecting all packages and papers that the households sorts out. A new waste regulation is under consideration where the responsibility for the household waste may change. The bulky waste from households is collected at recycling centers where the households leave it in different containers for different fractions. These recycling centers are formed different and the fractions offered in them also differ depending on in what municipality they are located.
Framgång i virtuella team : Hur chefer kan motivera sina medarbetare på distans
The work place is becoming more flexible and an increasing number of employees report to a leader in another location or country. The borders between different countries, work places and cultures are diminished to a greater extent than before. Working from a distance means new opportunities in terms of competence development, flexibility in working hours, tasks and resources, a larger platform for various career opportunities and an expanded network. The purpose with this study is to examine how leaders can create a successful virtual team and motivate remotely. The qualitative study is carried out through interviews with leaders and employees within Nielsen Nordic.

Automatisk Cykelväxel : Förstudie och datainsamling
A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question ?Which fauna passages can be found in Sweden, and how well do they work?? as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket.

KL-trä och limträ : hur råvarans kvalité tas tillvara i den färdiga produkten
Detta är en studie som behandlar hur väl kvalitén i trädet tas tillvara för sortimenten limträ och KL-trä. Limträ består av ett antal lameller som limmas samman med fibrerna i längdriktningen medan KL-trä är en krysslimmad skiva som består av en mängd sammansatta lameller. Trä är ett heterogent material som har skilda egenskaper beroende på var och hur det växt. Genom att sätta samman heterogena trälameller vill man skapa en homogenare produkt. Eftersom att produkterna används inom olika områden kan man tänka sig att det går att optimera användandet av råvaran till respektive produkt.
Kampen om ett föränderligt Arktis : En jämförande studie av Rysslands och Kanadas agerande i Arktis och Arktiska rådet.
The Arctic region is rich in natural resources such as oil, gas, minerals and fish. Climate change causes the Arctic ice melt, making resource extraction possible as well as opening up new transport routes through the Northwest Passage and the Northeast Passage. This has led to competition and cross-border strife among the Arctic States. The two largest states in the Arctic are Russia and Canada, which are also members of the Arctic Council. Russia and Canada are at the moment involved in several disputes regarding the Arctic territory where the ownership of the North Pole is one example.
Barnbokens kön Genusaspekter i litteratur och hos aktörer på marknaden
This Master's thesis examines some aspects of children's books for 9-12 year olds, and the children's books market, from a gender perspective. The main objective is to make a gender analysis of attitudes among children and other agents in the book market towards children's books of different qualities. Children's reflections on gender roles in the books and the importance of gender aspects for publishers in the field, are investigated. A combination of methods are used, including literary analyses, surveys of publication lists of the BTJ group Bibliotekstjänst interviews with children and questionnaires sent to children as well as to Swedish publishers of children's books. The analysis of children's books clearly shows that images of gender roles vary in different kinds of books which supports theories of gendered literature.
