This master thesis was produced with the intention of being a conceptual study of existing solutions and development of new solutions for a train mounted system for collection of brake dust particles from trains. Furthermore, an investigation of the risks attributable to brake dust and why the reduction of it is necessary was made. The problem was approached systematically through the adoption of

The current global scenario is such where impact on the environment is becoming a rising concern. Global automotive manufacturers have focused more towards hybrid and electric vehicles as both more aware customers and governmental legislation have begun demanding higher emission standards. One of the many ways that Volvo Car Group approaches this trend is by mild hybridization which is by assistin

Many regions around the world suffer from occasional or permanent droughts. Recent years have shown that although Sweden is not a water scarce country, it is vulnerable to dry peri- ods. As drinking water is applied in not only households, but within agriculture and indus- tries, this thesis explores the opportunities to achieve an improved management of water re- sources, by investigating the pos

The present study aimed at investigating the recent phenomenon termed Fear of missing out (FOMO), which builds on a feeling of constantly having to be connected to what other people are doing on social media in order to not miss out. The purpose of this study was to see if a link between FOMO and social media addiction is present and if Swedish university students’ well-being and academic performa

A prototype invasive (quasi-parasitic) thermal-neutron beam monitor based on isotropic neutron scattering from a thin natural Vanadium foil and standard $^3$He proportional counters has been conceptualized, designed, simulated, calibrated, and commissioned. As the beam monitor is invasive, very low neutron-beam attenuation is a necessary characteristic. Further, response linearity over as wide a r

The development of today’s energy-efficient dwellings often results in highly technical building solutions. We try to shield ourselves and our buildings as much as we can from the outdoors and subsequently loose an essential connection to the elements. Traditional design principals fall into oblivion and high-rise glass towers are justified with technological progress. By implementing selective st

Proteinupprening är ett viktigt och grundläggande steg för att kunna använda proteiner som läkemedel. Att utveckla en effektiv uppreningsprocess är viktigt utifrån såväl ett tidsperspektiv; som kostnads- och miljöperspektiv och målet med processen är att få ut så mycket rent protein som möjligt, utan att proteinets aktivitet reduceras. I det här projektet har en uppreningsprocess för proteas-X utvThe epidermal growth factor receptor (EGFR) is a receptor involved in cell proliferation. It is frequently overregulated in cancer cells, making it an attractive target for cancer therapeutics. One possible pharmaceutical is protease-X; a protein involved in the cleavage of the EGFR and thus, a way to regulate the receptor’s activity and lead the cancer cells to apoptosis. The aim of this thesis h

This thesis presents a numerical study of the beyond mean field extended Gross-Pitaevskii equation for a two-component self-bound Bose-Einstein condensate, supplemented by analytical work. We extend the quasi-two-dimensional system's mean field particle-particle contact interaction by quantum fluctuations (LHY-correction). We investigate the formation of self-bound droplets without external co

Several studies indicate an increase of alcohol consumption amongst older people. The aim of this study was therefore to examine nursing staff’s approach towards older people’s alcohol consumption in nursing homes. What attitude and experiences do nursing staff have concerning older people’s alcohol consumption? How do they relate to the older people’s self-determination regarding alcohol consumpt

Denna studie syftar till att ta reda på hur nyexaminerade musiklärare ser på sin identitet som musiklärare och huruvida de också identifierar sig som musiker. Genom en kvalitativ intervjustudie har tre informanter svarat på frågor kring valet att bli musiklärare, musiklärarutbildningen och deras tidiga yrkessocialisation. Vägen mot ett yrkesliv som musiklärare förefaller inte för informanterna somThis study aims to find out how newly graduated music teachers identify themselves as music teachers and whether they also identify themselves as musicians. Through a qualitative interview study, three informants have answered questions about the decision of becoming a music teacher. The path towards a professional life as a music teacher does not seem as a straight line. It is described as a comb

Thirty years after the fall of communism and fifteen years after Poland joined the European Union, there have been more steps backwards than forwards in regards to gender and sexual equality. From the very beginning, this has been a cause of tension between Poland and the EU. The aim of this thesis is to investigate how the conflicting constructs of sexual citizenship in Poland and Europe affect t

Tanzania as a tourist destination has traditionally had a nature-oriented focus for the past years. However, cultural heritage is becoming more and more viewed as a source for tourist attractions which raises questions on global and local impact on commodification of culture, and what sort of cultural activities are chosen to attract international and national tourists. This thesis focuses on the

Syftet med denna uppsats är att undersöka samt belysa hur andra generationens invandrare upplever sin identitet i ett mångkulturellt samhälle. Fem andra generationens invandrare intervjuades genom kvalitativa semistrukturerade intervjuer för att berätta hur de upplevde sin identitet. Intervjuerna grundades på tre huvudområden som berörde de externa faktorerna såsom familjens och samhällets påverka

När diskrepansen mellan vad människor säger och vad de gör uppmärksammas, väcks kognitiv dissonans som kan motivera beteendeförändring. Ett sätt att uppmärksamma denna diskrepans är genom hyckleriparadigmet, som är en tvåstegs sekventiell metod för att inducera kognitiv dissonans som visat sig ha potential att påverka beteende i miljövänlig riktning. Denna studie fokuserar på hyckleriparadigmets f

Föreliggande studie behandlar leksakssystemet Lego som semiotisk resurs, i termer av makt, sett utifrån ett kritiskt diskursanalytiskt perspektiv. Fokus ligger främst på produktserierna Lego City respektive Lego Friends representation av samhället, hur de ser ut, vad som skiljer dem åt, hur de förändrats över tid samt vad för budskap de förmedlar till barn. Syftet med studien är främst att illustr

Throughout colonial history, education has been used actively in an attempt to assimilate subaltern cultures into the colonizers’ realm. This study looks at the relationship between education of children in developing countries as a tool within sustainable development in relation to the colonial past and modern day coloniality. It looks at how the colonial use of education is recurring within a pr

Designing a spare part distribution network that fits the company’s strategy and customer requirement is a common problem for many organizations. Due to the advantages and disadvantages of different distribution network designs, it can be difficult to capture all requirements and contextual factors when designing the network. Furthermore, customer requirements and company strategy can change over
