Erosionsskydd på vattenkraftdammars uppströmsslänter
Syftet med detta examensarbete är att belysa de otydligheter i förfrågningsunderlag och bygghandlingar som Skanska har stött på i samband med kalkylering/utförande av dammrenoveringsprojekt i Norrland. De aktuella projekten är inom ramen för det dammsäkerhetshöjande åtgärdsprogram som Vattenfall driver mellan 2002 och 2007. Otydligheterna har mest kretsat kring den bristande beskrivning av hur erosionsskydden på kraftverkdammarnas uppströmsslänter ska utföras. Eftersom otydligheterna hitintills lösts på plats har Skanska även velat öka sina kunskaper om hur erosionsskydd kan utföras. Bakgrunden till Vattenfalls dammsäkerhetshöjande åtgärder grundar sig i flödeskommitténs riktlinjer för dimensionerande flöden och deras beslut att tillämpa RIDAS, vilket leder till att en del av deras anläggningar inte uppfyller de nya föreskrifterna.
En studie av Uppsala stads värmeö
The urban heat island is an area restricted to a city center where the temperatureis higher than its surrounding environment. The greatest temperature difference isfound at night when the weather is calm and the sky is clear of clouds. There are twomajor causes behind this phenomena and the first one is the use of energy forheating of houses. The heat leaks through the walls of the buildings and warms upthe surrounding mass of air. The second one is the use of building material whichstore the suns radiation on daytime and releases the heat during night.

Citizenship information is defined as the information the citizen needs to be able to take part in and influence the society. Since it is a democratic issue that information concerning the citizens role in society really reaches the citizens, it is of importance to study how the citizens proceed when they have a need for this information. The aim of this Masters thesis is to investigate how our eight informers proceed when they experience this need in a non-work situation. We performed qualitative interviews. The most important part of our interviews was the introduction of some fictitious problems to the informants.
Under Terra Novas Stenar : en osteologisk- & arkeologisk analys av ett bronsåldersröse på Gotland
This paper discusses an osteological- and archeological analysis of a cairn from the Bronze Age on Gotland. The osteological material consists of both burnt and and unburnt bones from both human and animal. The objective of this paper is to shed light on the individuals who were buried in the cairn. It is also to generate information about continuity in its use and patterns of distribution of the bones and grave-goods in the cairn. The osteological analysis show that a minimum of five human individuals is present in the osteological material.
Gud ge mig sinnesro att acceptera det jag inte kan förändra, mod att förändra det jag kan och förstånd att inse skillnaden..(En kvalitativ studie kring människor som genom frälsningen kommit ur ett långvarit missbruk och åter funnit mening med livet)
Syftet med denna uppsats har varit att undersöka hur olika vändpunkts processer i en kristen kontext kan se ut. Resultatet av studien visar att en betydande push-faktor ut ur missbruket för våra informanter bestått av de negativa konsekvenserna som missbruket fört med sig, initialt försämrad hälsa. Parallellt med detta upplevde informanterna att det var någonting utanför deras egen kontroll som ?drog? dem ur missbruket. Våra informanter har haft känslan av att någon leder dem och manar gott för dem.
Det är förstås lite konstigt att vara flicka : En queerfeministisk läsning av fyra Sigge Stark-romaner
In this essay, I make a queer feminist analysis of four novels written by the Swedish author Sigge Stark. The novels are: Uggleboet, Manhatareklubben, Cirkus Demonio och Baskerflickan. Using Judith Butler's theories I examine the relations between sex/gender and sexuality in the four books and show how the construction of gender is performed and the heterosexual normativity is jeopardized. I also examine whether, and if so how, Sigge Stark uses the romantic and the gothic genres to include transcending gender identities and sexualities in her work. The essay also includes a contextualisation of her prerequisities as an author and the necessity in performing a critical analysis of mass produced romantic literature..
Effektivisering av lagringsplatser. Ett förbättringsprojekt på Mekpart AB
Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.
Modellering av indunstning på Södra Cell Mönsterås
Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.
Går det att lära gamla hundar att sitta? : En studie om att ändra på en verksamhets utskriftsvanor.
The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.
Läraren i nutida svensk barn - och ungdomslitteratur
'Teachers in current Swedish child- and youth literature' is an essay that attempts to understand the reasons behind why authors portray teachers the way they do. The foundation and focus point of this essay are ten Swedish child and youth books that were all published during 2012. Throughout this essay I have analyzed the fictional teachers in these books using the discourse analysis method but also employed a gender perspective.
The main questions were these: Do the teachers presented in these books follow the curriculum LGR - 11, or do they represent the authors own education experience brought forward to current settings? Furthermore, was there a difference in how female and male teachers were represented? And if so what, possible reasons could account for that? The conclusions made were thus:
? The teacher characters within these books were mostly a throwback to days gone by, therefore reflecting the authors own memories of their school.
? They were mainly presented to the reader in a negative light which most likely has its roots in how Swedish school and Swedish teachers have been portrayed within the mass media.
? That there was indeed gender stereotyping in how female and male teachers were described..
Brothers in arms or partners in crime? A study of the gap between EU and USA in the cooperation against global terrorism.
In this thesis I analyse and discuss what impact the 2003 U.S lead intervention in Iraq, had for the cooperation against global terrorism between the European Union and the United States. Six years have passed since the Bush administration decided to go on with the intervention, even though they did not have the necessary UN mandate. Due to unsuccessful argumentation in favour of the intervention by the Bush administration, the world got divided. George W. Bush reference to a ?war on terror?, which passed almost unnoticed by Americans, rang alarm bells in many European countries.
Fasta driftställen på internet : Ett koncept på (juridiskt) lös grund?
The purpose of this essay is to examine and compare the news covering of Swedens three biggest cities (the metropolitan areas) and their surrounding areas with the covering of the rest of the country (the provincial areas) in two daily national newspapers, Aftonbladet and Dagens Nyheter. The aim has been to answer the following questions:- What amount of the news coverage in Aftonbladet and Dagens Nyheter concern the metropolitan areas compared to the provincial areas, and how do these two newspapers differ in the news covering of these areas?- Is there a difference in the news articles size and content, depending on weather they concern the metropolitan or the provincial areas?- How has the balance between news concerning metropolitan and provincial areas changed over the recent 20 years?The theories used in this study are News values, the media commercialization and Popular Journalism, and The Agenda Setting Theory. The method that has been used is a Quantitative Content Analysis.Despite the essays hypothesis, that the news coverage in the two newspapers would be dominated by material from the metropolitan areas, the result showed that a majority of the examined articles concern the provincial areas. It also showed that Aftonbladet has a bigger percentage of provincial news than Dagens Nyheter.
Lokalisering av ytor för hantering av jord- och bergmaterial i Södertörn
Syftet med arbetet var att identifiera ytor inom Södertörn där det skulle vara möjligt att etablera materialterminaler för hantering av byggbranschens jord- och bergmaterial. Förhoppningen var att detta kunde bidra till ett planeringsunderlag för en samordnad materialförvaltning inom regionen. Behovet och nyttan av fler materialterminaler har börjat uppmärksammas, men inga studier kring vilka platser som lämpar sig för ändamålet har tidigare genomförts utifrån svenska förhållanden. För att ta reda på vilka kriterier som definierade en bra materialterminalyta genomfördes en intervjustudie där tio aktörer med anknytning till materialhanteringsbranschen intervjuades. Kriterierna översattes till geografisk information och implementerades i GIS-programmet ArcMAP där det konstruerades en kartbild vilken visualiserade de ytor som var lämpliga respektive olämpliga att använda för ändamålet.
Kulturell Globalisering : en litteraturstudie
Today we are living in a time were impulses from other places and cultures constantly grow and the contact over the boundary is getting bigger. We se satellites pictures over the world, we hear about worldwide ecological problems, we learn about other different lifestyles, we cock food that are inspired from the worlds many kitchens, we shop more and we can travel to different parts of the world. My problem was to find out how cultural phenomenon spreads to a greater extent global and how this transference take place, but also be able to se what factors that has a part in the cultural spread.What I found with help from my literature study was that trough improved communication and transports has gained mobility in the world and people can take part off others culture.The world is shrinking and this means that human beings identity is changing and this create a so-called hybrid mixture. Culture is what we human beings create. Culture can be seen as a community phenomenon for the most parts.
