The transport of neutrons in long beamlines at spallation neutron sources presents a unique challenge for Monte-Carlo transport calculations. This is due to the need to accurately model the deep-penetration of high-energy neutrons through meters of thick dense shields close to the source and at the same time to model the transport of low- energy neutrons across distances up to around 150 m in leng

Fine-tuning of insulin release from pancreatic β-cells is essential to maintain blood glucose homeostasis. Here, we report that insulin secretion is regulated by a circular RNA containing the lariat sequence of the second intron of the insulin gene. Silencing of this intronic circular RNA in pancreatic islets leads to a decrease in the expression of key components of the secretory machinery of β-c

BACKGROUND AND OBJECTIVES: Dementia cases are expected to triple during the next 30 years, highlighting the importance of finding modifiable risk factors for dementia. The aim of this study is to investigate whether adherence to conventional dietary recommendations or to a modified Mediterranean diet are associated with subsequent lower risk of developing all-cause dementia, Alzheimer's disease (A

Recent socioeconomic changes have created and intensified paradoxical organizational tensions that companies in numerous industries, including the construction sector, need to address when organizing and managing their activities. The nature of these tensions has not been sufficiently explored in the existing construction management literature. Thus, this study analyzes tensions between control an

Temporariness of refugee protection has started to emerge as a new standard in the policies of European countries. Given this development, the article focuses on one specific issue related to this temporariness: how refugee status intertwines with the conditions for the granting, revocation and prolongation of national residence permits. What are the interconnections between refugee status, includ

Top civil society organisations (CSOs) face a particular legitimacy dilemma as they need to have leaders who are seen as legitimate by the elite groups they interact with, and by those they represent. This article investigates how they handle this dilemma by studying legitimation practices of newly appointed leaders. Based on Weber’s theory of authority and Pitkin’s theory of representation, the a

ype 2 diabetes (T2D) and obesity are multifactorial and polygenic metabolic diseases. Combinations of genetic and non-genetic risk factors such as risk SNPs, age, unhealthy diets, and physical inactivity increase the risk for these diseases. Emerging data also support a key role for epigenetic mechanisms in the pathogenesis of T2D and obesity. In this chapter, we summarize current knowledge of epi

Målbeskrivningen för den nya sexåriga läkarutbildningen lyfter fram att en läkare ska kunna visa förmåga att självständigt inleda diagnostik och behandling vid livshotande akuta tillstånd. Sedan 2017 har fler än tusen läkarstudenter i Lund genomgått 5 veckors utbildning i akut omhändertagande.Under utbildningen handlägger studenterna ett stort antal olika livshotande akuta tillstånd i fullskalesim

We study exposure to grading bias and provide novel evidence of its impact on mental health. Grading bias, which we interpret as over-grading, is constructed as the residual of final upper secondary school grades having controlled for results in a standardized test, itself not subject to grading leniency. Grading bias is further isolated by considering only within-school variation in over-grading

Antibiotic residues are being continuously recognized in the aquatic environment and in food. Though the concentration of antibiotic residues is typically low, adverse effects on the environment and human health have been observed. Hence, an efficient method to determine numerous antibiotic residues should be simple, inexpensive, selective, with high throughput and with low detection limits. Liqui

The article presents a semantic theory suggesting that equivalence and polyvalence are closely connected phenomena. The connection between them is utilised by making equivalence the basis of an argument for polyvalence within semantics, or in other terms, for a stratified semantics encompassing two levels of description. This argument from equivalence lends new support to frameworks assuming a str
