I dagens samhälle kan mycket förklaras med hjälp av fysik, men det finns också väldigt mycket som vi inte kan förklara eller förstår fullt ut. Ett exempel på detta är vår egen galax, Vintergatan. Hur bildades den? Varför ser den ut som den gör? Det finns flera teorier om hur det kan ha gått till, men mycket är ännu oklart för forskare. Teorierna måste testas. I dag består Vintergatan av många olikThe aim of this thesis is to get a better understanding of the evolution of the Milky Way stellar disc by looking at the abundance ratios for neutron-capture elements in thin and thick disc stars. In this project the formation of our Galaxy’s thin and thick disc was studied by analysing 10 different neutron-capture elements in field stars measured by Gaia-ESO. The methodology to determine if this

Lowering global carbon emission is one of the most pressing issues of our time. A rising interest in the role of cities in lowering emissions has been detected. Although urban areas are active entities in the production of carbon emissions they are also potential hubs for designing and implementing solutions. Such processes has been referred to as urban low carbon transitions (ULCT) by academics.

Standardmodellen är det teoretiska ramverk som beskriver partikelväxelverkningar på subatomär nivå. För att bekräfta teorins förutsägelser behöver experimentella data samlas in. I partikelfysik kan information om hur partiklar produceras och växelverkar med varandra erhållas genom att accelerara partiklar till höga energier och sedan låta dem kollidera. Detta är skälet att partikelkolliderarIn this Master thesis, two directions have been explored to improve the current parton shower algorithm of the event generator Pythia. Firstly, three choices of transverse-momentum-ordered evolution variable have been studied for final-state radiation in order to allow more flexibility within the algorithm. These three choices turn out to be valid but they lead to more technical implementations th

Car prevalence in society has a negative effect on both local and global environments. One way to tackle these problems is to restrict car traffic in city centres, this comes not only with effects on the environment. How car free zones can affect retail in cities is examined in this study. The study takes place in ten retail shops in the city centre of Lund along three streets. Customers are aske

Travel guidebooks are both sources of travel information and an object of consumption. In contemporary tourism, Information and Communication Technologies (ICT) make information not only available, but abundant and mostly free of charge. Therefore, considering that people still buy and use them, there must be something that makes travel guidebooks a valuable object. The research sets out to find w

Målet med den här rapporten var att undersöka möjligheten att vidare rena spillvattnet på Dows anläggning i Landskrona. Dow tillverkar vattenbaserade bindemedel från akryl monomerer. Spillvattnet innehåller metalliska joner, såpor, restmonomerer och restpolymerer. Idag så renas spillvattnet med ultrafiltrering (UF) där permeatet släpps iväg till det kommunala reningsverket för vidare rening. EfterThe aim of this report was to investigate the possibility of further cleaning of the wastewater at Dow in Landskrona. Dow produces water based adhesives from acrylic monomers. The wastewater contains different metal ions, surfactants, residual monomers and polymers. The wastewater at Dow is treated with ultrafiltration (UF) which produces a permeate that is sent to the municipal waste water treatm

Genom att observera och intervjua invånarna i Lund, kan man erhålla mycket information om historien och infrastrukturen för staden. Detta tyder på en särskilt självklar princip; om man studerar de mindre beståndsdelarna av ett system, så kan man erhålla egenskaper som är gällande för systemet i helhet. Detta är precis vad dagens astronomer utnyttjar för att lära sig mera om vårt universum. De minsThe first part of this thesis deals with the dynamical estimation of the Oort constants using proper motions and parallaxes provided from the Gaia-DR1 TGAS catalogue. The photometric information was provided by the 2MASS catalogue. The Oort constants calculated from the TGAS catalogue are compared to those obtained from the original Hipparcos catalogue in order to attempt to estimate how well Gaia
