Ambient pressure operando catalytic characterization by combining PM-IRRAS with planar laser-induced fluorescence and surface optical reflectance imaging

We present a combination of optical operando techniques that allow us to bridge the pressure gap in heterogeneous catalysis. By combining Polarization Modulated - InfraRed Reflection Absorption Spectroscopy (PM-IRRAS) with two dimensional-Surface Optical Reflectance (2D-SOR) and Planar Laser Induced Fluorescence (PLIF), we can simultaneously measure the adsorbed species on the catalyst surface, mo

The Challenges of Sustainable Investing

Over the past decades, investment preferences towards portfolio construction have changed from focusing solely on profit maximization, into a combination of good financial perfor- mance as well as a responsible sustainability outcome. The purpose of this paper is three- fold: first, to investigate whether a sustainable portfolio based on a high environmental, social and governance (ESG) score cont

Job crafting for female contractors in a male-dominated profession

In this paper, we explore the job crafting experiences of women who left permanent employment for contracting positions in Information Technology (IT), a sector widely considered male-dominated with limited career opportunities for women. This qualitative study is based on interviews with 24 female IT contractors. Findings show that through the flexibility and autonomy that come with contracting,

Emergent colon cancer and postoperative complications - risks and management

Background:Colorectal cancer in the third most diagnosed cancer in Sweden and the second most common cause of cancer-related death in Sweden and worldwide. 10-30% of the cases present as emergencies, of which 80% are caused by large bowel obstruction (LBO). Most of these patients undergo emergency resection which is associated with high rates of morbidity and mortality. To overcome the risk with e

X-ray scattering tensor tomography with circular gratings

Three dimensional (3D) information of the microstructure organization of various relevant materials in industry and nature is fundamental to master the understanding of their macroscopic properties. X-ray scattering tensor tomography provides 3D directional information on unresolved microstructures in large volumes, facilitating the investigation of the microstructural organization in statisticall

Unpaid Care for Elderly Parents and Labor Supply Among Older Working-Age Men and Women Across Europe

With population aging, more adults across Europe face competing demands of working for pay and caring for elderly family members. Associated tradeoffs are expected to be negative,gendered and vary across contexts with different levels of gender equality, public support for eldercare, and work-family balance. Using SHARE data from 2004 to 2020, we investigated how unpaid caregiving to independently

Genetic insights into resting heart rate and its role in cardiovascular disease

Resting heart rate is associated with cardiovascular diseases and mortality in observational and Mendelian randomization studies. The aims of this study are to extend the number of resting heart rate associated genetic variants and to obtain further insights in resting heart rate biology and its clinical consequences. A genome-wide meta-analysis of 100 studies in up to 835,465 individuals reveals

Dual phase grating interferometer for tunable dark-field sensitivity

Hard X-ray dark-field and phase contrast imaging using grating interferometry have shown great potential for medical and industrial applications. However, the wide spread applicability of the method is challenged by a number of technical related issues such as relatively low dose and flux efficiency due to the absorption grating, fabrication of high quality absorption gratings, slow data acquisiti

Anisotropic de Gennes Narrowing in Confined Fluids

The collective diffusion of dense fluids in spatial confinement is studied by combining high-energy (21 keV) x-ray photon correlation spectroscopy and small-angle x-ray scattering from colloid-filled microfluidic channels. We find the structural relaxation in confinement to be slower compared to the bulk. The collective dynamics is wave vector dependent, akin to the de Gennes narrowing typically o

Lead, cadmium, and mercury blood levels in schoolchildren in southern Sweden : Time trends over the last decades

To prevent diseases arising from exposure to toxic metals, more knowledge about their temporal changes is needed, especially in children, the most vulnerable group. This study follows temporal changes in blood lead (BPb), mercury (BHg) and cadmium (BCd) levels in schoolchildren (8–11 years old) from two cities in southern Sweden. One blood sample per 773 children was used for time trend analyses b

Alloying and Oxidation of PdAu Thin Films

The relation between catalytic activity and the presence of oxides on the catalyst’s surface has proven very complex, especially in the case of methane oxidation over Pd. While the metallic Pd surface and a thin, but at least two atomic layers thick, oxide film has been found catalytically active, a single-layer surface oxide or a too thick oxide film are both low-active. Unfortunately, under reac

K∗(892)0 and φ(1020) production in p-Pb collisions at sNN =8.16 TeV

The production of K∗(892)0and φ(1020)resonances has been measured in p-Pb collisions at sNN = 8.16 TeV using the ALICE detector. Resonances are reconstructed via their hadronic decay channels in the rapidity interval -0.5 < y < 0 and the transverse momentum spectra are measured for various multiplicity classes up to pT = 20 GeV/c for K∗(892)0and pT = 16 GeV/c for φ(1020). The pT-integrated yields

Comparing different techniques for obtaining molecular size distributions of glycogen

Glycogen is a hyperbranched glucose polymer, serving as a major energy reservoir in animals. Characterization of the size distributions of complex branched polysaccharides helps in the understanding of their structural and functional properties. This study compared the effectiveness of various techniques in analyzing glycogen size distributions, namely size-separation-based techniques (size exclus

Hormone status in occupational toluene exposure

Twenty toluene-exposed rotogravure printers, without signs of solvent-induced toxic encephalopathy, had lower median plasma levels of follicle stimulating hormone (FSH) (3.2 vs. 4.9 IU/L; p = .02) and luteinizing hormone (LH) (6.4 vs. 7.2 IU/L; p = .05) and also lower serum levels of free testosterone (7.8 vs. 86.8 pmol/L; p = .05), respectively, than 44 unexposed referents. The individual time-we

Imagining circular carbon : A mitigation (deterrence) strategy for the petrochemical industry

Petrochemical producers both rely upon and generate some of the most problematic substances in the current age of socioecological crisis: fossil fuels and plastics. With mounting calls to cap fossil fuel extraction as well as plastics production, the industry appears to be caught between a rock and a hard place. Nonetheless, betting on continuously increasing global plastic demand, petrochemical p
