We investigate the interfaces and polarity domains at the atomic scale in epitaxial AlN and GaN/AlN grown by hot-wall metal organic chemical vapor epitaxy on the carbon face of SiC. X-ray diffraction, potassium hydroxide (KOH) wet chemical etching, and scanning transmission electron microscopy combined provide an in-depth understanding of polarity evolution with the film thickness, which is crucia

Human-induced salinization caused by the use of road deicing salts, agricultural practices, mining operations, and climate change is a major threat to the biodiversity and functioning of freshwater ecosystems. Yet, it is unclear if freshwater ecosystems are protected from salinization by current water quality guidelines. Leveraging an experimental network of land-based and in-lake mesocosms across

The self-assembly of amyloid β peptide (Aβ) to fibrillar and oligomeric aggregates is linked to Alzheimer’s disease. Aβ binders may serve as inhibitors of aggregation to prevent the generation of neurotoxic species and for the detection of Aβ species. A particular challenge involves finding binders to on-pathway oligomers given their transient nature. Here we construct two phage–display libraries

Evaluating competing metaphor theories against each other implies the need for theory-independent criteria of comparison. We propose translation validity, the closeness in which theoretical constructs and operationalizations match one another, to be such a criterion. Applying this to Conceptual Metaphor Theory (CMT) and Deliberate Metaphor Theory (DMT) we note that the translation validity of CMT

Objective: The prevalence of functional gastrointestinal (FGI) symptoms and irritable bowel syndrome (IBS) is high in the society, but the etiology is mainly unknown. This population-based, cross-sectional study aimed to examine the associations between self-reported IBS or gastrointestinal (GI) symptoms within the past 2 weeks and concomitant diseases, drug consumption and family history of disea

Complementary and alternative medicine (CAM) is used as a complementary intervention in psychiatric healthcare. The reasons for using or not using CAM in psychiatric care in Sweden, and how such decisions are taken, are largely unknown. The aim was to investigate arguments for and against the use of CAM in Swedish psychiatric care, and how decisions are made. Interviews with 10 persons in decision

India and Pakistan are entrenched in an antagonistic relation that is constantly on the verge of, once more, developing into an armed conflict. There are, presently, no signs of conciliatory initiatives on the level of state-to-state interactions, which, contrariwise, tend to uphold incompatible conceptions of regional order, nationhood and the Partition as a constitutive moment. The latter furthe

Objectives: To explore communication and engagement in everyday situations between persons with young-onset dementia (YOD) living in a nursing home (NH) and the caregivers. Methods: The study draws on ethnographic methods aligned with participatory design. Three residents with YOD living in a NH and eight staff members were recruited. A narrative approach was used for data collection and analysis.

How people wake up and regain alertness in the hours after sleep is related to how they are sleeping, eating, and exercising. Here, in a prospective longitudinal study of 833 twins and genetically unrelated adults, we demonstrate that how effectively an individual awakens in the hours following sleep is not associated with their genetics, but instead, four independent factors: sleep quantity/quali

In Sweden, personal assistance is one form of support for persons with certain functional impairment. The aim of personal assistance is to give compensatory support to individuals so that they can enjoy the right to live a life like anyone else. This article explores what kind of support parents who have functional impairments and apply for personal assistance may need when they have underage chil

The underlying mechanisms for statin-induced myopathy (SIM) are still equivocal. In this study, we employ Drosophila melanogaster to dissect possible underlying mechanisms for SIM. We observe that chronic fluvastatin treatment causes reduced general locomotion activity and climbing ability. In addition, transmission microscopy of dissected skeletal muscles of fluvastatin-treated flies reveals stro

This paper focuses on tech giants as active drivers of a phase of globalization characterized by growth in digital services trade combined with a general shift to intangible assets. By analysing how Google, Amazon and Microsoft organize their innovation activities, we show that they continuously monopolize knowledge while outsourcing innovation steps to other firms and research institutions. The p

Cartilage oligomeric matrix protein (COMP) is an emerging regulator of tumor progression. The aim of this study was to evaluate the expression of COMP in periampullary adenocarcinoma with respect to prognostic value for survival and relapse, levels of fibrosis and infiltrating immune cells. COMP expression was evaluated using immunohistochemistry in primary tumors and subsets of paired lymph node

Relative telomere length (RTL), an indicator of senescence, has been shown to be heritable but can also be affected by environmental factors, such as parental effects. Investigating heritability as well as parental effects and rearing environment can help us to understand the factors affecting offspring telomeres. Moreover, how phenotypic parental traits linked with fitness can impact offspring RT

Experimentella metoder har blivit alltmer populära inom en rad olika samhällsvetenskapliga ämnen under de senaste åren. I den här boken får du lära dig vad ett experiment är, när ett experiment passar, och hur du designar och genomför experiment. Dessutom berättar författarna om experimentets historia i samhällsvetenskapen, kritik mot experiment som metod, etiska aspekter och något om framtidsutsi

The aesthetic outcome is crucial in a breast reconstruction. Our aim was to evaluate the intra- and interrater reliability of an aesthetic outcome assessment scale with digital photos of breast reconstructions in two-dimensional (2D) and three-dimensional (3D) format. Thirty-three women with delayed breast reconstructions, consecutively participating in a five-year follow-up between November 2019
