We investigate the impact of a galaxy’s merger history on its system of satellites using the new VINTERGATAN-GM suite of zoom-in hydrodynamical simulations of Milky Way-mass systems. The suite simulates five realizations of the same halo with targeted ‘genetic modifications’ of a z ≈ 2 merger, but resulting in the same halo mass at z = 0. We find that differences in the satellite stellar mass func

BACKGROUND: Acute allergic reactions (AARs) occur shortly after exposure to an allergen, and the severity is on a continuum. Systemic corticosteroids (CS) are mainstay treatment of moderate to severe AARs, whereas those at risk of the most severe AARs (ie, anaphylaxis) are also recommended prescription of epinephrine autoinjectors. There is limited research on the impact of AARs not fulfilling the

Water damage affects both residents and buildings. Issues include moisture, climate impact and repair costs that amount to immense resources. Because of these, immense resources research is important to undertake to reduce and limit the extent and effects of water damage. This study aimed to compile and review the literature on water damage in buildings. Literature distribution, the status, conseq

A class of quasiperiodic superlattice structures, which can be generated by the concurrent inflation rule A→AmB and B→A (where m=positive integer), has been studied both theoretically and experimentally. Given that the ratios between the thicknesses of the two superlattice building blocks, A and B, are chosen to be γ(m)=[m+(m2+4)1/2]/2 (known as the ‘‘precious means’’), then the x-ray- and electro

Chiral compounds containing nitrogen heteroatoms are fundamental substances for the chemical, pharmaceutical and agrochemical industries. However, the preparation of some of these interesting scaffolds is still underdeveloped. Herein we present the synthesis of a family of P-stereogenic phosphinooxazoline iridium catalysts from L-threonine methyl ester and their use in the asymmetric hydrogenation

Förebyggande av oönskade graviditeter och sexuellt överförbara infektioner (vad jag kallar "contracepting") behandlas ofta som ett medicinskt eller hälsovårds- problem snarare än en social fråga. Till följd av detta, förblir mycket av det vardagliga arbetet som preventivmetoder innefattar osynligt. Unga människor i synnerlighet talas oftare om än med när det kommer till deras användning av preventContraception is a complex phenomenon with differing meanings, expressions, and materialities depending on its historical, social, and cultural context. In this thesis, I depart from the conceptualisation of contraception as the prevention of both pregnancies and sexually transmitted infections (STIs) and I name these practices through the collective term of contracepting.
