Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits understanding of the mechanisms behind the generation of spectral curves, w

Sea salt aerosol particles are highly abundant in the atmosphere and play important roles in the global radiative balance. After influence from continental air, they are typically composed of Na+, Cl-, NH4+, and SO42- and organics. Analogous particle systems are often studied in laboratory settings by atomizing and drying particles from a solution. Here, we present evidence that such laboratory st

OBJECTIVE: To examine whether iron intake and genetically determined iron overload interact in predisposing to the development of childhood islet autoimmunity (IA) and type 1 diabetes (T1D).RESEARCH DESIGN AND METHODS: In The Environmental Determinants of Diabetes in the Young (TEDDY) study, 7,770 genetically high-risk children were followed from birth until the development of IA and progression t

Open Source Software (OSS) has become an increasingly important knowledge asset in modern economies. However, the economic impact of OSS on countries’ GDP is ambivalent due to its public good character. Using a cross-country panel from 2000 to 2018, including 25 of the largest EU countries plus the USA, Japan, Korea, Canada, China, Norway, and Switzerland, matching OSS commits to GitHub to macroec

In this perspective article, we call for more engagement with the unexplored politics of residual emissions. Residual emissions are those emissions that remain at the point of net zero, despite abatement efforts. Unlike carbon dioxide removal, which has been the focus of a lively research and policy debate, the notion of residual emissions remains relatively unexplored so far. With the mainstreami

En god hälsa är grundläggande för barns och ungas utveckling, och en förutsättning för socialt och ekonomiskt deltagande under livet. Således innebär bördan av psykisk ohälsa stora utmaningar för både individ och samhälle. Det har rapporterats att den psykiska ohälsan ökar i Sverige dels bland den yngre befolkningen, dels i vissa grupper av den vuxna befolkningen. Det finns svårigheter med att mätThe purpose of this thesis is to improve the understanding of factors related to mental ill-health, and itsdistribution, in the Swedish population. The thesis consists of four studies. In study I, we find thatbetween the years 1994 and 2011, the probability of receiving a psychiatric inpatient diagnosisincreased by 12.6 percent, while the relative and absolute income-related inequalities in diagno
