The City of Gothenburg has an urgent need to upgrade its public transport. The capacity of its light rail transit (LRT) has reached maximum capacity within the inner city limits years ago. The construction of an underground metro will be very expensive and time consuming due to the soft clay beneath the city. The apparent need of developing another type of mass rapid transit (MRT) is urgent. An elevated metro have turned out to be a success in Greater Vancouver, but is it possible for the system to operate well in Gothenburg with its narrow streets and current land use; will its route coexist with the current LRT or will the noise disturb people too much?.

När du arbetar med teckensnitt, vare sig du skapar ? eller helt enkelt väljer ett teckensnitt, finns det konsekvenser till följd av skapandet och/eller valet. Läslighet och läsbarhet ligger i hjärtat av teckensnitts utformning ? men principerna kring läslighet och läsbarhet är flexibla och kan komma att bortses ifrån, beroende på den tänkta kontexten för teckensnittet. Ett grepp om historiken bakom användningen av vissa teckensnitt, såväl som kunskap om de möjliga associationer de kan väcka är också av stor betydelse när man arbetar med teckensnitt. Forskning kring teckensnitt och läsbarhet har visat att en viss vikt ? för ett givet teckensnitt, är optimal för läsbarheten vid punktstorleken 10.

Hur påverkar högre utbildningsnivå brottslighet? Den här uppsatsen undersöker effekt av eftergymnasial utbildning på våldsbrott respektive stöld-, rån- och häleribrott. Vår första hypotes är att eftergymnasial utbildning har en minskande effekt på våldsbrott genom högre alternativkostnad av brott samt att psykologiska faktorer påverkas positivt. Vår andra hypotes är att eftergymnasial utbildning har en ökande effekt på stöld-, rån- och häleribrott via högre avkastning till följd av mer kunskap för planering och utförande av denna typen av brott. Vidare förmodas en högre utbildningsnivå  generera mer tillgänglig egendom vilket leder till tilltagande incitament för stöld-, rån- och häleribrott.

Ända sedan graffiti började förekomma i Sverige för ca 20 år sedan har den, nästan utanundantag, ständigt ökat i omfattning. Sveriges kommuner har försökt bemöta den illegalagraffitins framfart med olika sorters förebyggande åtgärder. Dock har dessa metoder sällanutvärderats kvantitativt, och resultaten av de implementerade åtgärderna är ofta osäkra. Syftetmed denna studie är att med ekonometrisk metod utvärdera två av dessa metoder; lagligaväggar och snabbsanering. Förhållandet mellan dessa åtgärder och anmälda graffitibrottundersöks med OLS-regressioner genomförda för en panel med 172 svenska kommuner underperioden 1996-2004.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

When harvesteing ley there is always mechanical losses from the harvest machines. During the last years the roundbalers with knives,cutting the material-are more common, This use increase the mechanical losses of material. MATERIALS AND METHODS The roundbaler which used in this test was a Krone Vario Pack 1500 Multi Cut. This roundbaler has 17 knives. The theoretical length of cut was 64 mm. During the test we stretched a rubber tarp under the balechamber and collected the materials which fell down from the balechamber.

The food prices in Finland and Sweden have been a subject for discussion for several years back in time. From the opponents against further European integration one have often heard that the EU and EMU entrance have made an negative impact on the food prices. This study show us that the impactof the entrances was extensive in the short run but rather finite and insignificant in the long run.Other important factors that describe why food prices fluctuate is also discussed. The mainconclusion is that other factors than the EU and EMU entrance should be seen as more likely whenit comes to the development of food prices. The essay is principally based on quantitative statistics of food prices, analysed in the light of economic theory..

Den 15 december 2008 genomfördes en reform för arbetskraftsinvandring från tredje land i Sverige. Syftet med förändringen är att underlätta rekrytering utanför EU/EES och Schweiz för att minska bristen på arbetskraft. Genom att förenkla och utveckla systemet till ett av de mest öppna i världen, hoppas man locka till sig fler arbetare för att minska underskottet på arbetsmarknaden.Tidigare forskning visar att en reform som minskar restriktioner för inträde till landet, generellt kommer att resultera i ett ökat inflöde av migranter. I denna uppsats undersöks, med hjälp av en ekonometrisk analys, om Sveriges reform av arbetskraftsinvandring gett en positiv effekt på antalet migranter som ansöker om ett arbetstillstånd. I den ekonometriska analysen används panel data, med data från före och efter reformen.

Health and fitness are two controversial and not easily defined topics that affect people in our modern society every day. We believe that we can find a link between individualism, globalization and the stress concerning weight and appearance ideals. Our bodies have turned into a popular subject for the media, and there is no indication that the interest will decline. As the world gets more artificial, "natural" ideals are getting more attention, such as the concept of a strong and healthy body. But there is also a downside, for example with health issues such as cardiovascular disease increasing following the birth of high-fat diets.

Bath has been a part of human history for a long time. Today bathing/swimming inmunicipal pools is for people of all ages and it is possible to take swimming courses,exercise or enjoy recreation. The municipal indoor pool of Hogdalen in Sweden wasbuild in the sixties and has had problems with high levels of heterotrophic bacteria. Thefacility has two larger pools, one adventure park for young kids, two smaller bath tubsand a jacuzzi. To improve water quality UV light and coal filter were installed inOctober 2009 to the already existing purification system.

ABSTRACT Title (English): New technologies, same needs? A qualitative research of media usage in two generations, in the light of modern uses and gratifications research Title (original): Ny teknik, samma behov? En kvalitativ undersökning av två generationers mediebruk i ljuset av den moderna bruks- och belöningsforskningen Language: Swedish  Author: Frida Ivansson Tutor: Sven Ross Course: Media and Communication Studies, Bachelor's Thesis.  Period: Spring term 2013 University: Department of Journalism, Media and Communication (JMK) atStockholm University Purpose/Aim: The purpose of this paper is to, in the light of todays uses and gratification research, highlight the differences in media use in adolescents and adults. I focus on the informants' television viewing and I compare this cross-generational, and in relation to other media use. Material/Method: The method I used in this thesis is qualitative interviews. My choice fell on this method because I believe it to be the most suitable for obtaining the data needed.

Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.

Background: Mastitis in dairy cattle is a common ailment worldwide. A cause of mastitis can be bacteria such as Escherichia coli. Mastitis is not a deadly ailment and sometimes the dairy cows show no symptoms but if certain virulence genes are present in the bacteria that cause the mastitis, the bacteria can be transmitted to humans and cause severe diseases. The potential presence of enterohemorrhagic Escherichia coli (EHEC) in particular would be a major concern for human health.Aim: The aim for this study was to analyze the presence of virulence genes known to be present in E.coli strains isolated from dairy cows with mastitis in Sweden.Method: A Qiagen BIO ROBOT EZ1 was used to purify DNA from 90 bacterial cultures. A panel of virulence genes were amplified and biotinylated from the purified DNA by PCR and an E.coli based DNA microarray was used to detect presumed virulence genes in E.coli.Result: There were no samples that had all the genes traditionally used to classify E.coli as EHEC or potential EHEC.

The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
