The response of a position-sensitive Li-glass scintillator detector being developed for thermal-neutron detection with 6 mm position resolution has been investigated using collimated beams of thermal neutrons. The detector was moved perpendicularly through the neutron beams in 0.5 to 1.0 mm horizontal and vertical steps. Scintillation was detected in an 8 × 8 pixel multi-anode photomultiplier tube
BACKGROUND: Hepatitis B virus (HBV) is a hepatotropic deoxyribonucleic acid (DNA) virus which causes death. More than 300 million people have chronic liver infections globally and about 600,000 people die annually from acute or chronic complications of hepatitis B infection. Recent studies conducted in Ethiopia showed moderate endemicity (3-7.8%) of HBV among pregnant women. However, there is pauc
Med anledning av oroligheter i Rinkeby tunnelbanestation har företrädare för Polisen, MTR Nordic, Rinkeby-Kista Stadsdelsförvaltning, FastPartner, Securitas, Säkerhet Ordningsbevakning SOB (SOB) och Trygghetscentralen (TC) arbetat utifrån Brå:s samverkansmodell för lokalt brottsförebyggande arbete.Denna utvärdering undersöker om samverkansmodellen varit framgångsrik, om de lokala brottsförebyggand
This chapter investigates the characteristics of a successful voluntary sickness fund in early twentieth-century Sweden. The practices of the Seamstresses Sickness and Burial Fund reveal how a working-class organisation functioned in improving the living conditions of its members. When it was first founded in 1898, it was a small all-female and marginal sickness fund, but by the 1930s it had devel
Urbanisation and climate change are urging cities to find novel pathways leading to a sustainable future. The urban context may be viewed as a new experimentation space to accelerate the transition to a circular economy. Urban symbiosis and circular economy are emerging concepts attracting more and more attention within the urban context. Moreover, new business models are emerging around sharing a
In this paper, we consider the distributed reactive power sharing control problem for an autonomous inverterbased microgrid with resilience for communication faults, which may be caused by partial communication link failures or some channel manipulation attacks. Under the standard decoupling approximation for bus angle differences, the reactive power flow of each inverter can be controlled by mani
Shared mobility options, such as car sharing, are often claimed to be more sustainable, although evidence at an individual or city level may contradict these claims. This study aims to improve understanding of the effects of car sharing on transport-related emissions at an individual and city level. This is done by quantifying the greenhouse gas (GHG) emissions of the travel habits of individuals
Traditionally, biogenic volatile organic compound (BVOC) emissions are often considered a unidirectional flux, from the ecosystem to the atmosphere, but recent studies clearly show the potential for bidirectional exchange. Here we aimed to investigate how warming and leaf litter addition affect the bidirectional exchange (flux) of BVOCs in a long‐term field experiment in the Subarctic. We also ass
This chapter situates John Rawls’ just savings principle in a discussion about how much a nation-state should save. The main question addressed is whether this principle is a viable alternative to the dominant utilitarian theory of optimal growth. Rawls certainly gives savings a different aim (i.e., to create and maintain just institutions) and introduces additional permissibility conditions on rThis chapter situates John Rawls’ just savings principle in a discussion about how much a nation-state should save. The main question addressed is whether this principle is a viable alternative to the dominant utilitarian theory of optimal growth.

Presented is a review of the accomplishments, of the light-element program, conducted at the Lund Ion-Beam Analysis Facility. A detailed account is given of the current experimental setup at the total Ion-Beam Analysis Chamber, which is equipped with two Double-Sided Silicon Strip Detectors for charge particle detection, a silicon drift detector for PIXE analysis, an electrostatic deflection syste
Directed self-assembly of nanoparticles (NPs) is a promising strategy for bottom-up fabrication of nanostructured materials with tailored composition and morphology. Here, we present a simple and highly flexible method where charged magnetic aerosolized (i.e. suspended in a gas) NPs with tunable size and composition are self-assembled into nanostructures using combined electric and magnetic fields
Working conditions of 20 Swedish pig transport drivers (PTD) were assessed by a questionnaire, a workshop, and recorded postures and movements during on-farm loading, driving, unloading at abattoir and vehicle cleaning. High arm positions and high frequencies of shoulder problems indicated an excessive physical load on shoulders. Extreme crouching postures inside vehicles and high frequencies of l
The migrational propensity of neuroblastoma is affected by cell identity, but the mechanisms behind the divergence remain unknown. Using RNAi and time-lapse imaging, we show that ADRN-type NB cells exhibit RAC1- and kalirin-dependent nucleokinetic (NUC) migration that relies on several integral components of neuronal migration. Inhibition of NUC migration by RAC1 and kalirin-GEF1 inhibitors occurs
In many species that raise young in cooperative groups, breeders live an exceptionally long time despite high investment in offspring production. How is this possible given the expected trade-off between survival and reproduction? One possibility is that breeders extend their lifespans by outsourcing parental care to non-reproductive group members. Having help lightens breeder workloads and the en
PURPOSE OF REVIEW: This review provides a concise overview of recent advances in cerebrospinal fluid (CSF) and blood-based biomarkers of Alzheimer's disease lesions. RECENT FINDINGS: Important recent advances for CSF Alzheimer's disease biomarkers include the introduction of fully automated assays, the development and implementation of certified reference materials for CSF Aβ42 and a unified proto
Background: In cardiovascular disease, prevention strategies targeting standard modifiable cardiovascular risk factors (SMuRFs; hypertension, diabetes, hypercholesterolaemia, and smoking) are crucial; however, myocardial infarction in the absence of SMuRFs is not infrequent. The outcomes of individuals without SMuRFs are not well known. Methods: We retrospectively analysed adult patients with firs
