Vi bor i Vintergatan, en av Universums många galaxer. Men hur bildades den, och alla andra galaxer vi kan se genom våra teleskop? Rådande teorier hävdar att för många miljarder år sedan, när Universum var ungt, bildades först små dvärggalaxer, som sedan slogs ihop till att bilda stora galaxer såsom Vintergatan. Men många detaljer i den här processen är fortfarande oklara. Därför vill vi titta på sIn this project aperture photometry has been performed for stars in the direction of the dwarf spheroidal galaxy Leo II. The observations were carried out using the Stro ̈mgren filters v, b and y, during three consecutive nights in 2003, out of which all but the first one turned out to be non-photometric. The data was reduced and calibrated (using the metallicity calibration of Calamida et al. (20

This thesis takes its outset in the newly coined expression ‘Hell Joseon’ used by the youth in South Korea. ‘Hell Joseon’ is a comparison between today’s society and the pre-modern Joseon Dynasty. By asking “what are the main characteristics of life in ‘Hell Joseon’ from a youth perspective?”, I arrive at the following conclusion. Life in ‘Hell Joseon’ is highly characterized by discrepancies betw

En människa exponeras och angrips varje dag av virus och bakterier och immunförsvaret skyddar oss från dessa angrepp. Immunförsvaret utgörs av vita blodkroppar som bildas i benmärgen och sprids vidare ut i kroppen. De vita blodkropparna finns i många olika varianter och varje variant har en specifik uppgift. Lymfocyter är en typ av vita blodkroppar och kan dela in i två huvudgrupper: Blymfocyter oToday antibodies are an important part in the treatment of diseases such as cancer and Guillain–Barré syndrome. It is of course important to be able to regulate the levels of the antibodies in the treatment. In this study a general method for antibody production were investigated. The antibody construct was made for transportation out of the cell. Four different tagged variants of an antibody wer

In today’s society, traffic congestion is a major problem in several aspects. Apart from the obvious problem that people are losing valuable time due to the resulting delays, it also has negative impact on as well the economy as the local and global environment. With the development of sensors and navigation support, it has now become possible and thus of interest to study optimal routing of vehic

Bakgrund: sjukvården genomgår ett paradigmskifte där dagens sjukvårdsinrättningar har svårt att möta patienternas komplexa behov. Nya riktlinjer ska hjälpa till att stärka bevisen för evidensbaserad design (EBD) och mycket tyder för att enbart enkelsalar bör rekommenderas. Trots detta saknas omvårdnadsforskning inom området utifrån ett patientperspektiv. Syfte: studiens syfte var att undersöka pat

Autenticitet är ett begrepp som genomsyrar nutida musikvetenskap. Begreppet har flera innebörder. Denna kandidatuppsats använder autenticitet i betydelsen tidstrogenhet eller s.k. ljudande autenticitet. Arbetet är en studie av tradjazzfestivalen i Hällevik 2016 där sju orkestrar, enligt festivalprogrammet, har ambitionen att spela jazz så som man gjorde kring 1920 i USA. Uppsatsen besvarar frågan Authenticity is a concept that permeates contemporary musicology. The term has several meanings. In this bachelor thesis authenticity means fidelity to the time period or so-called sounding authenticity. The work is a study of the traditional jazz festival in Hällevik 2016 where seven bands, according to the festival programme, play jazz as it was played around the 1920’s in the US. The essay answ

Corruption is often compared to a double-edged sword. While acting as a “necessary evil” to avoid bureaucratic inefficiencies such as red tape to grease the wheels of commerce, there are many other studies expressing their concerns regarding the negative effects corruption has on growth. Based on previous empirical evidence and theories such as the “rent-seeking” theory that conceptualize the rela

Marknaden för brobyggnad i Sverige är idag så god att företagen tvingas tacka nej till förfrågningar på grund av tidsbrist. Det är svårt att rekrytera nya konsulter eftersom det råder brist på arbetskraft med rätt kompetens, för att undvika att tacka nej till arbete är en potentiell lösning på tidsbristen att effektivisera arbetet. I samarbete med Skanska Tekniks brogrupp i Malmö utreder därför deThe bridge construction industry in Sweden is prospering. The situation is such that companies are forced to decline work due to lack of time. In addition, the recruitment of new consultants has been difficult owing to a shortage of labour with the right competency. To avoid the situation where companies are forced to decline new projects due to lack of resources, focus should be on improving the

Naturvårdsverket uppger att antalet potentiellt och bekräftat förorenade områden i Sverige under 2016 uppgick till 85 000. Siffran visar på att problemet med kontaminerad mark är tämligen omfattande. En grundsten i den svenska miljörätten är principen om att förorenaren, i detta fall verksamhetsutövaren, betalar. Vad händer om den som orsakat en föroreningsskada inte finns tillgänglig och kan stäl

Aktivering av arbetslösa har diskuterats brett inom såväl akademin som politiken under de senaste decennierna. Fokus har ofta varit på förändrade kontraktsrelationer mellan arbetslösa och samhället där rättigheter kontra krav på motprestationer har varit i fokus. Tidigare forskning kring erfarenheter av arbetslöshet har ofta framhävt dess negativa aspekter av stigmatisering, skam och social exklud

This thesis intends to explain the change of strategies to address coca plantation in Colombia before and after the 2016 Peace agreement. To do so, I build a theoretical model that draws on securitization/de-securitization theory and ripeness/readiness theories. The former theory is used to explain what kind of change was there between the different strategies. In this sense, I claim that policies

The purpose of this thesis was to provide Uniti Sweden AB with a solution proposal regarding which motors, sensors, control units and other electrical components needed for a steer-by-wire system of a test car. The thesis resulted in new motors, sensors and electrical components for the steer-by-wire system of the test car. The solution proposal made it possible to laterally steer the test car by

The purpose of this project is to study the read performance of transparent database-backed file systems, a meld between two technologies with seemingly similar purposes, in relation to conventional file systems. Systems such as the ARC middleware relies on reading several millions of files every day, and as the number of files increases, the performance suffers. To study the capabilities of a dat

Many companies today have a security system containing of devices such as cameras and other devices with some trigger functionality built in. It’s essential to be able to control all existing triggers in a security system for it to work flawlessly. As the number of triggers increases, the security system in question becomes more complicated to configure. Therefore, making configuration from an eas

Due to computation-intensive nature of LDPC decoders, a lot of research is going towards efficient implementation of their original algorithm (SPA). As "Min-Sum" approximation is basically an overestimation of SPA, this thesis investigates more accurate, yet area efficient, approximations of SPA, to select an optimum one. In a general comparison between main approximation methods (e.g. LUT,

Populism has become a political catchphrase across the world, spanning across the entire political spectrum in various forms. In Spain, the left-wing populist party Podemos is the most significant case, adopting a post-marxist perspective less focused on the economy than orthodox marxism. In light of this, this thesis examines their main economic program through use of Fairclough’s Critical Discou

The purpose of this study was to describe and analyze the home care services quality work, and to what extent the quality work actually safeguards the quality aspects formulated as important by the municipality, the home care services and the users. The purpose was further to investigate in which way the presence of private home care providers has influenced quality work and the view on quality. T

Den här studien syftar till att undersöka, diskuterar och problematiserar hur politiska nätaktivister, så kallade clicktivister, mobiliserar och kommunicerar under en organisationskris. Studien tar sin utgångspunkt i fallet Bokmässan. Organisationens Facebooksida blev en plats för intensiv debatt när det blev känt att den högerpopulistiska tidningen Nya Tider skulle delta på mässan. Studien undersThe purpose of the study is to problematize and discuss the mobilization and communication of online-based activists, so-called “clicktivists”, in an organizational crisis. The study examines the case of the Gothenburg Book Fair, where the organization’s Facebook page became an arena for debate because of a far-right newspaper’s plans to attend the book fair. The study examines the discourses prod
