Luminescence properties of undoped Li6Y(BO3)3 (LYB) crystals grown by the Bridgman method as well as undoped and praseodymium doped LYB crystals grown by the Czochralski method were studied under excitation by ultraviolet light, synchrotron radiation and electron beam in the temperature region of 5–300 K. The emission bands peaking at 4.8, 3.76 and 2.95 eV were found in undoped Czochralski-grown c

In Amazonia, interfluvial groups such as the Naduhup (Makú) peoples of the northwest Amazon have tended to be less visible than riverine peoples in the historical record, but are also more likely to maintain their cultural and linguistic identity over time. Hence the languages of these groups may offer insights into Indigenous histories that have otherwise been largely overlooked or obliterated. L

In this study, we examine the way access to welfare provision for migrants is articulated discursively among three right-of-center parties in Sweden. For this, we suggest two theoretical advances. First, deploying the concept of the right-wing continuum, we highlight the gradual and reciprocal alignment between mainstream right-of-center and radical-right populist parties. Second, by resorting to

Argonauts of industry: Knowledge gathering and technologies in use in Sweden’s industrial breakthroughIn this article we explore how knowledge transfer about industrial production and new technologies affected Sweden’s rapid industrialisation in the second half of the nineteenth century. Focusing on two case studies taken from the Swedish glass and gunpowder industries, we argue for the importanceArgonauts of industry: Knowledge gathering and technologies in use in Sweden’s industrial breakthroughIn this article we explore how knowledge transfer about industrial production and new technologies affected Sweden’s rapid industrialisation in the second half of the nineteenth century.

Every Sunday, sermons are delivered in over a thousand churches within the Church of Sweden. In each of them, theology is not just applied but also ”done”, or formulated. Using the concept of “theologizing” and building on theories from two professors in homiletics, David Schnasa Jacobsen and Leonora Tubbs Tisdale, this thesis empirically investigates in what ways preachers in the Lutheran Church

Just over seven years into the implementation of the Peace Agreement between the Colombian government and the FARC-EP in October 2016, the armed conflict has reconfigured and reactivated in several parts of the country. In the Putumayo department, tensions between the state, various armed groups, and rural communities over territory and crops for illicit use persisted, and even accentuated in the

Sexual homicide has been heavily studied, yet the majority of the studies have focused on male offenders killing female vic-tims (MFSH), thereby neglecting male-on-male sexual homicide (MMSH), i.e., instances where an adult male offender murders an adult male victim. To summarize the current understanding of this crime type, a systematic review was conducted. The objective was to provide a clearer

Choir singing has been suspended in many countries during the Covid-19 pandemic due to incidental reports of disease transmission (Hamner et al. Citation2020). The mode of transmission has been attributed to exhaled droplets, but with the exception of a study on tuberculosis from 1968, there is presently almost no scientific evidence of increased particle emissions from singing (Loudon and RobertsChoir singing has been suspended in many countriesduring the Covid-19 pandemic due to incidental reportsof disease transmission.

The public sphere can be seen as a meeting place where people with different backgrounds, interests and worldviews interact. It is a virtual or physical site where political opinions are formed and news reported, but also where various forms of knowledge circulation take place. In this paper, the latter dimension will be in focus, in particular the circulation of academic knowledge. The perspectiv

In the early weeks of 2024, as the catastrophic war in the Gaza Strip began to inflame the broader region, the stability of the Middle East appeared to be once again at the center of the U.S. foreign policy agenda. In the initial days after Hamas’s October 7 attacks, the Biden administration moved two aircraft carrier strike groups and a nuclear-powered submarine to the Middle East, while a steady

Det finansiella ramverket är inte källan till eventuella brister i den offentliga välfärden eller infrastrukturen. Tvärtom har det bidragit till ekonomisk stabilitet och hög tillväxt, skriver Fredrik N G Andersson och Lars Jonung.

X-ray multi-projection imaging (XMPI) has the potential to provide rotation-free 3D movies of optically opaque samples. The absence of rotation enables superior imaging speed and preserves fragile sample dynamics by avoiding the centrifugal forces introduced by conventional rotary tomography. Here, we present our XMPI observations at the ID19 beamline (ESRF, France) of 3D dynamics in melted alumin

Here, we present new models to fit small angle X-ray scattering (SAXS) data for the characterization of ion tracks in polymers. Ion tracks in polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI) and polymethyl methacrylate (PMMA) were created by swift heavy ion irradiation using 197Au and 238U with energies between 185 MeV and 2.0 GeV. Transmission SAXS measurements were performed

Ti3C2Tx MXene (or "MXene" for simplicity) has gained noteworthy attention for its metal-like electrical conductivity and high electrochemical capacitance-a unique blend of properties attractive toward a wide range of applications such as energy storage, healthcare monitoring, and electromagnetic interference shielding. However, processing MXene architectures using conventional methods often deals

X-ray time-resolved tomography is one of the most popular X-raytechniques to probe dynamics in three dimensions (3D). Recent developments in time-resolved tomography opened the possibility of recordingkilohertz-rate 3D movies. However, tomography requires rotating thesample with respect to the X-ray beam, which prevents characterization of faster structural dynamics. Here, we present megahertz (MH
