An x-ray spectrometer includes: an x-ray plasma source that produces first x-rays; an x-ray optic in optical communication with the x-ray plasma source and that: receives the first x-rays from the x-ray plasma source; focuses the first x-rays to produce second x-rays; and communicates the second x-rays to a sample that produces product x-rays in response to receipt of the second x-rays and second
The protein parkin, encoded by the PARK2 gene, is vital for mitochondrial homeostasis, and although it has been implicated in Parkinson’s disease (PD), the disease mechanisms remain unclear. We have applied mass spectrometry-based proteomics to investigate the effects of parkin dysfunction on the mitochondrial proteome in human isogenic induced pluripotent stem cell-derived neurons with and withou
Objective: To develop evidence-based guidelines for the management of giant cell arteritis (GCA) as a complement to guidelines in other areas of rheumatology, issued by the Swedish Society of Rheumatology. Methods: A working group selected key areas for recommendations, reviewed the available evidence, and wrote draft guidelines. These were discussed and revised according to standard procedures wi
Aims. We have measured and calculated lifetimes of high lying levels in Nb II, and derived absolute transition probabilities by combining the lifetimes with experimental branching fractions. Methods. The lifetimes were measured using time-resolved laser-induced fluorescence in a two-photon and two-step excitation scheme. The branching fractions were measured in intensity calibrated spectra from a
Background: Nail polish is known to contain potentially hazardous chemicals that have been linked to adverse health effects after overexposure. Formaldehyde is used as an antimicrobial, preservative, and nail hardener in select nail products, yet it is a recognized carcinogen and potent allergen in allergic contact dermatitis. Objective: The aim of this study was to investigate whether formaldehyd
Recently, seven Earth-sized planets were discovered around the M-dwarf star TRAPPIST-1. Thanks to transit-timing variations, the masses and therefore the bulk densities of the planets have been constrained, suggesting that all TRAPPIST-1 planets are consistent with water mass fractions on the order of 10%. These water fractions, as well as the similar planet masses within the system, constitute st
Palliative care philosophy is based on a holistic approach to patients, but research shows that possibilities for living up to this philosophy seem limited by historical and administrative structures. From the nurse perspective, this article aims to explore nursing practice in specialised palliative homecare, and how it is influenced by organisational and cultural structures. Qualitative, semi-str
Discussions and debates about traditional values of equity and inclusion have increased in recent years, and participants in these discussions include professional heritage institutions, journalists of the daily press and the public through social media. Museums, as keepers of cultural stories and heritage under their auspices, are increasingly examining their role in shaping a narrative of divers
This thesis treats the intersection between two of the largest transformations we are seeing within our society today; the cloud and the Internet-of-Things (IoT). The aim of this thesis is to investigate different ways to model and control a network of cloud services so that timing-critical IoT applications can make use of them. Examples of such applications can be autonomous and mobile robots, sm
Short biography of the Swedish American clarinetist Artie Seaberg (1904–1957) who played with the Original Dixieland Jazz Band 1920–1925.

Hållfastheten och därmed kvaliteten på planglas varierar kraftigt beroende på förekomsten sprickor i glasets yta. Sprickorna fungerar som brottanvisningar vilket medför att man måste räkna med stora säkerhetsfaktorer då glas belastas i olika byggnadskonstruktioner. Trä som konstruktionsmaterial har en liknande problematik där man utvecklat virkessortering för att kvalitetsklassning. I den här förs
Aims. The central region of a circumstellar disk is difficult to resolve in global numerical simulations of collapsing cloud cores, but its effect on the evolution of the entire disk can be significant. Methods. We used numerical hydrodynamics simulations to model the long-term evolution of self-gravitating and viscous circumstellar disks in the thin-disk limit. Simulations start from the gravitat
