Based on field measurements in 26 Ethiopian homes, we have estimated an average indoor air exchange rate (AER). In laboratory settings, using on-line methods, we have burned common solid biofuels (charcoal, wood, cow dung, crops residue) in a traditional way, thereby generated airborne particles, and assessed various aerosol characteristics. All the fuels generated PM2.5 (particles smaller than 2.

To extend the output DC power range of energy harvester from μW to mW, the 29.5 GHz rectifier using vertical nanowire Tunnel Field-Effect Transistor (VNW-TFET) is presented in this paper. Advantaged by the low threshold voltage, very steep characteristics, and its ability to operate below 60mV/decade, VNW-TFET is a promising device in rectifier design for low power applications. By analyzing the r

To have a successful career in engineering, students need both technical engineering skills and non-technical engineering skills (NTES) in the transition to professional life. To address NTES in engineering education, the concept of six compulsory ‘engineering days’ were introduced in two engineering programs at the undergraduate level. The importance of different NTES for industry has been evalua

In a questionnaire, participants judged the increase in SARS-CoV-2 virus exposure when moving closer to an infected person. Earlier studies have shown that the actual increase in virus exposure is underestimated and the present study replicated and extended these studies. The primary purpose was to investigate to what extent questionnaire judgments about hypothetical situations can predict judgmen

In this interview, Prince Sisowath Thomico, a cousin of Cambodian King Sihamoni who has been politically active in a range of political movements and parties, discusses the role of the monarchy and what royalism might mean in Cambodia today, three decades after the Cambodian monarchy was reintroduced. He reflects on the historical trajectory of the Cambodian monarchy and royalism, and analyses how

Objective: This study examined the prevalence and long-term survival of atrial fibrillation (AF) in the older population. Methods: Data was recruited from the longitudinal SNAC study from baseline (2001–2004) for up to 10 years. Results: The population comprised 6,904 persons (59% women) (mean age 73.9 years). The prevalence of AF was 4.9% and increased with age. The hazard ratio (HR) for death in

This paper presents a method for evaluating the potential for injury in any traffic scenario involving road user interactions based on trajectory data from a few hours of data of typical traffic conditions. The basic idea was to evaluate to what extent interactions at a location are limited in speed, direction, and whether the interactions happen at a safe speed. Specifically, the method works by

Recently approved anti-amyloid immunotherapies for Alzheimer's disease (AD) require evidence of amyloid-β pathology from positron emission tomography (PET) or cerebrospinal fluid (CSF) before initiating treatment. Blood-based biomarkers promise to reduce the need for PET or CSF testing; however, their interpretation at the individual level and the circumstances requiring confirmatory testing are p

Mars science fiction (SF) has interacted with Mars science ever since the advent of modern science, and has largely influenced public perceptions of the red planet and its exploration. In this chapter, it is argued that it has not only shaped numerous (mis)conceptions about the possibilities of indigenous Martian life, eventual human settlement and its challenges, but that it also has a large outr

The purpose of this study was to examine men’s and women’s experiences of honor-based violence through six podcast episodes and to identify any differences and similarities between the genders. The theoretical frameworks applied in this study to understand honor-based violence were intersectionality and Foucault’s theory of power. A purposeful selection was used to select six episodes in total. Al

This study aimed to understand how older adults experience loneliness and how a community center can reduce feelings of loneliness. Using a qualitative method, we conducted semi-structured interviews with six older adults, aged 65 and above, who regularly visit a community center in Skåne. The analysis focuses on three different themes: experiences of loneliness, the meaning of social life, and th

The interaction between a low angle grain boundary in front of a crack tip and the emerging plasticity from the tip of a microstructurally short edge crack subjected to fatigue loading has been studied. The modeling rests solely on discrete dislocations, were the geometry is described by dislocation dipole elements in a boundary element approach and the plasticity, restricted to one slip plane, to

It is well known that the behaviour of short cracks differs from that of long cracks due to the relatively large plastic zone and strong influence from the surrounding microstructure, and for very low growth rates, it is important to account for discrete dislocations within the material. In this study, a discrete dislocation model is presented for the study of the growth behaviour of a short edge

Venous thromboembolism (VTE) involves blood clot formation in veins, resulting in serious health issues. Fibrinogen, a crucial clotting protein, consists of three polypeptides encoded by the fibrinogen genes: alpha (FGA), beta (FGB) and gamma (FGG). We genotyped most common missense variants in the fibrinogen genes in relation to VTE, recurrence and family history in Malmö Thrombophilia Study, inc

The influence of the deformation speed in C-ring tests in Ringer's solution on crack initiation and propagation of extruded Mg10Dy and Mg10Dy1Nd is investigated. Deformation speeds varying from 2 to 0.012 mm/min allow corrosion times from a few minutes to hours. Both the crack initiation force (higher for Mg10Dy1Nd) and displacement (higher for Mg10Dy) increase with decreasing deformation speed up
