Motivated by the observed bottom-light initial mass function (IMF) in faint dwarfs, we study how a metallicity-dependent IMF affects the feedback budget and observables of an ultra-faint dwarf galaxy. We model the evolution of a low-mass 8 × 108 M⊙) dark matter halo with cosmological, zoomed hydrodynamical simulations capable of resolving individual supernovae explosions, which we complement with
Den 1 juni 2018 infördes ett frivillighetsrekvisit i den svenska våldtäktsbe-stämmelsen i 6 kap 1 § BrB. Det nya rekvisitet innebär att avsaknad av ömse-sidig frivillighet ligger till grund för straffansvar. Målsägandens agerande och hur personen uttryckt frivillighet är av central betydelse för bedömningen. I min uppsats har jag undersökt vilka gränser målsägandens frivillighet ställs inför när dOn June 1, 2018, a voluntariness requirement was introduced in the Swedish rape provision in Chapter 6, Section 1 of the Swedish Penal Code (BrB). The new requirement implies that the absence of mutual voluntariness forms the basis for criminal liability. The actions of the victim and how their expressed voluntariness is assessed are of central importance in the evaluation. In my essay, I have exa
The catalyst layer (CL) in polymer electrolyte membrane (PEM) fuel cells is one of the key components regulating the overall performance of the cell. In PEM fuel cells, there are two CLs having identical composition for hydrogen oxidation (HO) and oxygen reduction (OR) reactions. There are four phases inside the CL, namely: carbon, Pt particles, ionomer and voids. In this work, a micro-model of th
The first stages of planet formation take place in protoplanetary disks that are largely made up of gas. Understanding how the gas affects planetesimals in the protoplanetary disk is therefore essential. In this paper, we discuss whether or not gas flow can erode planetesimals. We estimated how much shear stress is exerted onto the planetesimal surface by the gas as a function of disk and planetes
We investigate the evolution of the abundance of fluorine in the Milky Way thick and thin discs by means of detailed chemical evolution models compared with recent observational data. The chemical evolution models adopted here have already been shown to fit the observed abundance patterns of CNO and α-elements as well as the metallicity distribution functions for the Galactic thick and thin disc s
We analyze the size evolution of pebbles accreted into the gaseous envelope of a protoplanet growing in a protoplanetary disk, taking into account collisions driven by the relative sedimentation speed as well as the convective gas motion. Using a simple estimate of the convective gas speed based on the pebble accretion luminosity, we find that the speed of the convective gas is higher than the sed
Curvature in lipid-based biomembranes provides compartmentalization in cells and can act as regulator of biological activity in living systems. The study of these biomembranes require novel model systems and new methods. In this work I have used a supported phospholipid bilayer on a hexagonal array of silicon nanowires. The nanowires impose curvature on the supported lipid bilayer and the resultin
This dissertation aims to analyse how in Saudi Arabia’s perception the Muslim Brotherhood went from being a political asset to a security threat for the Kingdom. It does so by examining the reoccurring historical (in)security elements of the regime in order to understand why they are perceived as a threat. By examining the origin and ideology of the Brotherhood we gain an understanding on how the
Syftet med denna uppsats är att redogöra för de olika lagändringar som gjorts av våldtäktsbrottet sedan brottsbalken infördes år 1962. Det är en rättshistorisk undersökning av vilka ändringar som gjorts, vad som låg till grund för att dessa ändringar gjordes för att till sist uppmärksamma dagens samhällsdebatt kring införandet av en samtyckesreglering. Brottet våldtäkt har sedan brottsbalkens infö
I Sverige har det dödliga skjutvapenvåldet ökat under 2010- och 2020-talen. De flesta av brotten är kopplade till pågående konflikter i de kriminella mil-jöerna i utsatta områden i de svenska storstadsregionerna. Hur denna vålds-brottslighet ska förhindras har blivit en viktig politisk fråga. En av de strategier som har använts för att minska förekomsten av dödligt skjutvapenvåld har varit att sk

I denna uppsats behandlar jag brottet oaktsam våldtäkt i den svenska brottsbalkens (BrB) 6 kap. 1 a §. Bestämmelsen infördes i samband med 2018 års lagförändringar i sexualbrottslagstiftningen, i folkmun samtyckeslagen. Straffansvar kräver bla. grov oaktsamhet i förhållande till rekvisitet den andra personens icke-frivilliga deltagande, det är häri uppsatsens fokus uteslutande ligger. Jag beskriveIn this essay, I present the offense negligent rape, regulated in chapter 6 paragraph 1 a in the Swedish Penal Code. The provision was established in connection with the legislative change of Sweden’s sexual offences legislation in 2018, commonly called the consent regulation. Criminal liability requires, among other, gross negligence in relation to the necessary prerequisite the other person’s no
Hantering av PAH kontaminerad asfalt har i denna rapport studerats med syftet att utreda moment som berör hanteringen från de tidiga projekteringsfaserna fram till slutlig förvaring, destruktion eller återvinning av den kontaminerade asfalten. I rapporten följs denna tidslinje från litteraturstudien, där läsaren får med sig en allmän och fördjupad kunskap om det berörda ämnet, till konkreta metode
Clusters of stem cells at the tip of each plant shoot give rise to all of its above-ground organs, effectively controlling the development and the physical shape of the plant. A core network of negative feedback between CLAVATA3 (CLV3) and WUSCHEL (WUS) regulate the stem cells existence and behaviour in Arabidopsis thaliana. Despite the close relationship of these genes, their expression domains a
