1. What limits the luminosity of red supergiants?
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : The observed upper limit of the luminosity of red supergiants, often called the Humphreys-Davidson limit, has recently been shown to be independent of metallicity and to not be explainable by single star evolution – findings that both contradict established ideas of the origins of the limit. It is now known that the vast majority of stars with sufficient mass to possibly evolve into red supergiants above the limit interact with companion stars at some point during their lives. LÄS MER
2. A Statistical Approach to Understand the Evolution of Exotic Butterfly Species
Kandidat-uppsats, KTH/Matematisk statistikSammanfattning : The alarming rate at which we see the decline in biodiversity due to human activity has raised concerns about the well-being of our planet. Butterflies which serve as pollinators are an essential part of many ecosystems and sensitive indicators of environmental changes and can provide valuable insight into how ecosystems function and evolve.

Uppsats för yrkesexamina på grundnivå, Högskolan Dalarna/BildSammanfattning : This study examines art teachers' challenges and opportunities and the impact of Lgr22 on art teachers' didacalicum in theory and practice. The study is based on three qualitative informant interviews carried out in an exchange of knowledge. LÄS MER
4. Intermediate-mass black hole binary as an origin of super-massive black holes
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Galactic nuclei contain super-massive black holes (SMBHs), nuclear stellar clusters (NSCs), or both. In the NSC, intermediate-mass black holes (IMBHs) are likely to reside and form highly eccentric binaries. Over time, the orbit of a binary could harden via interaction with surrounding low-mass stars. LÄS MER
5. Nu ska vi äntligen få prata med Skånetrafiken : en kritisk utvärdering av samverkansprocessen för trafikförsörjningsprogrammet
Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Svensk kollektivtrafik är en av de offentliga sektorer som de senaste decennierna präglats av idén om decentralisering och effektivisering genom upphandling. Detta har resulterat i att kollektivtrafiken idag styrs av flera aktörer som är beroende av att samverka med varandra. LÄS MER
