Operando Surface Optical Reflectance Microscopy Study of Corrosion Film Growth on a Ni-Cr-Mo Alloy During Anodic Polarization

The solid-liquid interface, where corrosion reactions occur, is notoriously difficult to study in operando conditions. Few experimental techniques can provide surface sensitivity and spatial and temporal resolution and are compatible with liquid environments. 2-Dimensional surface optical reflectance (2D-SOR) is an emerging optical technique providing microscopic information with high temporal res

Human Factors for Cybersecurity Awareness in a Remote Work Environment

The conveniences of remote work are various, but a surge in cyberthreats has heavily affected the optimal processes of organizations. As a result, employees' cybersecurity awareness was jeopardized, prompting organizations to require improvement of cybersecurity processes at all levels. This paper explores which cybersecurity aspects are more relevant and/or relatable for remote working employees.

Effect of phosphomimetic point mutations on the ADP-ribosylation activity of PARP16

Introduction: Phosphomimetic residue and D-loop mutants have been created and their effect studied in the enzyme PARP16. Background: It is known that PARP16 is phosphorylated, and where the phosphorylation sites are, but not how this affects ADP-ribosylation activity. As of yet, there are no reliable ways to obtain 100% phosphorylated PARP16, so it is instead mimicked with amino-acids with simil

Human-Material Relationships around 4000 BCE : Continuity and Change in South Scandinavian Flint Tool Production Technologies

Recent studies have found that explanations of the neolithisation of South Scandinavia based on dichotomies between migration (population replacement) and diffusion (in-group change) are insufficient if we want to understand the complexity and variation involved in what happened during the centuries around 4000 BCE. However, these contrasting narratives still overshadow discussions on change in So

Recent Advances in Optical Sensing for the Detection of Microbial Contaminants

Microbial contaminants are responsible for several infectious diseases, and they have been introduced as important potential food- and water-borne risk factors. They become a global burden due to their health and safety threats. In addition, their tendency to undergo mutations that result in antimicrobial resistance makes them difficult to treat. In this respect, rapid and reliable detection of mi

Oxygen Exposure and Tolerance Shapes the Cell Wall-Associated Lipids of the Skin Commensal Cutibacterium acnes

Cutibacterium acnes is one of the most abundant bacteria on the skin. Being exposed to oxygen and oxic stress, the secretion of the bacterial antioxidant protein RoxP ensures an endogenous antioxidant system for the preservation of skin health. To investigate the impact of the antioxidant RoxP on oxidation of the bacteria, wildtype and an isogenic roxp mutant were cultured in anaerobic and oxic co

Characteristics and Attitudinal Changes of Senior Citizens and Persons with Functional Impairments Involved in a Citizen Science Project on Housing Accessibility

Citizen Science (CS) projects targeting senior citizens and persons with functional impairments are rare, and interest among citizens to become involved in such remains uncertain. There is a lack of systematic analyses as to what distinguishes citizens’ willingness to contribute, and what such involvement could lead to in terms of acquired skills or changed attitudes. Based on a Swedish CS project

Holistic management of patients with progressive pulmonary fibrosis

Progressive pulmonary fibrosis (PF) is a complex interstitial lung disease that impacts substantially on patients’ daily lives, requiring personalised and integrated care. We summarise the main needs of patients with PF and their caregivers, and suggest a supportive care approach. Individualised care, education, emotional and psychological support, specialised treatments, and better access to info

Relative quadrupole moments of exotic shapes at ultrahigh spin in 154Er : Calibrating the TSD/SD puzzle

Transition quadrupole moments, Qt, of two ultrahigh-spin, collective structures in 154Er have been measured for the first time using the Doppler Shift Attenuation Method (DSAM). Data were acquired at the ATLAS accelerator facility of Argonne National Laboratory, using the Gammasphere detector array. A thick, gold-backed 110Pd foil was bombarded by a beam of 48Ti ions at 215 MeV. The Qt for each ba

Nanotools for biosensing and manipulating cells

In medical research and within the field of Biology, it is important to find effective tools for probing and manipulating cells, as well as tools for detecting biomolecules. These tools should be sensitive, with high specitivity, and, if aimed at interacting with cells, they should be minimally invasive. In this thesis, I investigated the potential of various nanotools for these purposes. Specific

Measuring historical inequality in Africa: What can we learn from social tables?

Limited knowledge of African inequality trajectories hampers our understanding of the drivers of heterogenous inequality outcomes in Africa today, and leads to major omission in debates about global inequality. In recent years, African economic history has advanced towards the reconstruction of full income distributions of African economies using 'social tables'. In this paper, we take stock of th

Diverging Trends in the Incidence of Spontaneous Intracerebral Hemorrhage in Sweden 2010-2019 : An Observational Study from the Swedish Stroke Register (Riksstroke)

Introduction: Although ischemic stroke incidence has decreased in Sweden over the past decade, trends in spontaneous intracerebral hemorrhage (ICH) incidence are less well delineated. In this time period, there has been a dramatic increase in use of oral anticoagulants (OAC). The aim of our study was to investigate incidence trends in spontaneous first-ever ICH in Sweden between 2010 and 2019, wit

The first U–Pb age for shocked zircon from the Mien impact structure, Sweden, and implications for metamictization-induced zircon texture formed during impact events

Shocked zircon from impactites from the Mien impact structure, Sweden, has been investigated with the aim to date the impact event and correlate the degree of U–Pb age resetting with shock-related microtextures. In situ U–Pb spot isotope analyses of granular and microporous–granular zircon grains from the impact melt rocks give an age of 120.0 ± 1.0 Ma. This essentially confirms the previous best

Coalition bargaining time and governments’ policy-making productivity

What is the purpose of lengthy negotiations when a coalition government forms? Do they make a difference in coalition policy-making? Negotiations that produce policy agreements between coalition partners have been suggested to strengthen the capacity of coalition governments to make policy reforms. We argue that bargaining time, regardless if it results in a written policy agreement or not, is an
