Bergerosion i utskovskanaler
Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.
Shakespeare på svenska : En komparativ analys av fyra sonettöversättningar gjorda av Martin Tegen och Eva Ström
Skolverket menar att populärkultur, däribland dataspel, är användbara verktyg för att nå elevernas livsvärldar i religionskunskapsundervisningen.Den här uppsatsen undersöker den religionsdidaktiska potentialen hos Mass Effect-spelen i gymnasieskolan utifrån följande frågeställningar:Får rätt och fel handling något utrymme i Mass Effect? På vilket sätt? Vad är rätt och fel i spelkontexten?Kan Mass Effect fungera som stödstruktur för att arbeta med stoff och förmågor som är en del av religionskunskapens etikundervisning och i sådana fall på vilket sätt?Spelkontexten utforskas genom en analys av hur spelens Paragon/Renegade-system bedömer olika handlingar. Systemet jämförs med plikt-, konsekvens- och dygdetiska förhållningssätt; dessa är etiska modeller som tas upp av styrdokumenten. En av spelens beslutssituationer granskas också utifrån en beslutsmodell och styrdokumentens etiska modeller bidrar här med teoretisk och kursplanemässig förankring.Undersökningen visar att flera av de områden som ska ingå i gymnasieskolans etikundervisning kan beröras genom att låta olika element i Mass Effect-spelen möta ämnets stoff. Processen verkar ur ett didaktiskt perspektiv både berikande för spelkontexten och illustrerar komplexiteten hos etiska modeller och fattandet av etiska beslut.
GIS-modellering av habitat för vitryggig hackspett (Dendrocopos leucotos) som hjälpmedel i naturvårdsplanering på landskapsnivå :
The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.
Kvarnkretssimulering för test av styrsystem
This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.
Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet
Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations were performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

Massdigitalisering och kvalitativ digitalisering: En jämförelse av digitaliseringen på nationalbiblioteken i Norge och Sverige
The purpose of this thesis is to compare mass digitization and qualitative digitization, to see how the digitization process and the digitalized material differ. The study emanates from the mass digitization as it is performed at the National Library in Norway, and the qualitative digitization at the Royal Library in Sweden. The method used is document studies combined with mail interviews. The focus is upon the practical operation, to which counts: ?purpose & selection?, ?preparation, image capturing and processing?, ?metadata & text encoding?, ?quality assessment?, ?storage of digital originals and copies? and ?display?.
Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen
The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.
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.

Effekten av träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden på kvantitativa rörelsetester hos friska kvinnor
Bakgrund: Medvetenhet om kropp och rörelse nämns ofta som en viktig fakor i att öka prestationsförmåga, undvika skador, nå högre livskvalitet och förbätta sjukdomstillstånd. Det har länge funnits ambitioner att förbättra rörelse genom ökad medvetenhet. Feldenkraismetoden är en metod för att förbättra rörelse genom förhöjd rörelsemedvetenhet och är förenlig med nutida vetenskap men förhållandevis lite empirisk forskning stöder metodens effektivitet. De flesta tidigare studier har varit på någon form av dysfunktion och ofta subjektiv upplevelse snarare än objektiva värden. Det har varit svårt för Feldenkraispedagoger att finna rätt mätmetoder för att utvärdera metoden.Syfte: Studiens syfte är att utvärdera effekten av träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden på rörelse hos friska personer genom kvantitativ mätning.Metod: Friska kvinnor i en experimentgrupp (n=4, 30±7 år) och en kontrollgrupp (n=4, 26±2 år) testades med fem kvantitativa rörelsetester; one-leg standing balance, one-leg standing long jump, standing triple jump, star excursion balance test och upper quarter Y-balance test, innan och efter en intervention ledd av en auktoriserad Feldenkraispedagog där experimentgruppen genomgick tio träningsfällen enligt Feldenkraismetoden under fem veckors tid.Resultat: Signifikant förbättring (P?0,05) i förhållande till både förtest och kontrollgrupp sågs vid star excursion balance test för vänster ben.Slutsats: Träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden verkar kunna leda till förbättring i kvantitativt mätt rörelse hos friska kvinnor.
Socialarbetarens livspussel - En kvantitativ och kvalitativ studie
The purpose of this thesis is to shed light on the various factors that influence the balancebetween the working lives and family lives of social workers. The research questions posedwere: Do social workers consider there is a conflict between their working lives and familylives? Which factors make maintaining a balance between working life and family life moredifficult and which make it easier to do so? How do social workers describe equality betweenthe sexes in their own family? Regarding methodology, the selection method is strategic andcombines data sources with quantitative and qualitative methodologies. The material collectedand via online survey, targeted to 120 municipal employees social workers in a district councilin a big city, and through interviews with four social workers in a rural community. The studywas performed using gender theory and the demand-support-control model.
Den ofrivillige nationalisten : En komparativ studie av nationalism i Sverige under finanskrisen 2008-2011 utifrån dagspress
Mass communication today stands for a great number of information in the developed welfare state of Sweden. This was also the case during the social and economic financial crisis in 2008-2011. At this point, the majority of the population chose to turn to the newspapers to look for further information. This essay seeks, in a comparative and theoretical way, and with the help of two theories of nationalism, to understand how the Swedish culture and tradition can be explained via newspapers, and in what way these portray nationalism. What it also sets out to investigate further is what kind of impact it might exercise over the population in its position as one of the leading providers of information.
Feng shui i trädgården :
Our environment affect us, not least gardens. By practising the ancient Chinese art feng shui, one could find tools how to create harmony and balance in gardens. By paying attention to different energies working with colours, shapes and materials one can create a nice garden with good feng shui. The philosophy, however, includes much more than what plants or what hard materials to choose in the garden. It describes different energies, the movement of energies, which we can learn to live in harmony with.
Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan
Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.
