Neighborhood socioeconomic status and aortic stenosis : A Swedish study based on nationwide registries and an echocardiographic screening cohort

Background: Aortic stenosis (AS) is the most common valvular heart disease in developed countries, confers high mortality in advanced cases, but can effectively be reversed using endovascular or open-heart surgery. We evaluated the association between AS and neighborhood socioeconomic status (NSES). Methods: We used Swedish population-based nationwide registers and an echocardiography screening co

Disturbances in brain energy metabolism in insulin resistance and diabetes and Alzheimer's disease — Learnings from brain imaging biomarkers

Medical imaging techniques, such as structural and functional magnetic resonance imaging and positron emission tomography, have been used to gain a better understanding of the alterations of the metabolic processes in the brain relating to type 2 diabetes melltius, insulin resistance and Alzheimer's disease. These studies have shown that there are several similarities in the effects that these see

Fragmentation, commodification and responsibilisation in the governing of flood risk mitigation in Sweden

The purpose of this paper is to increase our understanding of the governing of flood risk mitigation in advanced liberal society, through an in-depth Swedish case study. By combining social network analysis and genealogy, this paper investigates who is involved, how they organise, their modes of thinking, how they mitigate flood risk, as well as how such regime of practises have come into being. T

Visual adaptations of diurnal and nocturnal raptors

Raptors have always fascinated mankind, owls for their highly sensitive vision, and eagles for their high visual acuity. We summarize what is presently known about the eyes as well as the visual abilities of these birds, and point out knowledge gaps. We discuss visual fields, eye movements, accommodation, ocular media transmittance, spectral sensitivity, retinal anatomy and what is known about vis

Regional evidence of smallholder-based growth in Zambia's livestock sector

Growth in the smallholder-based livestock sector, characterized by increasing number of animals, commercialization and processing of animal products have historically provided a decisive contribution to raising the incomes of farm households, and to the broader process of agricultural transformation. In this paper, we use a mixed methods approach to examine the processes of extensive and intensive

Numerical contribution to segmented chip effect on residual stress distribution in orthogonal cutting of Inconel718

Segmented chip morphology has a significant influence on distribution of residual stress and surface topography on machined surface in machining difficult-to-cut materials. In this paper, Coupled Eulerian and Lagrangian (CEL) model is employed to investigate the effect of segmented chip on surface integrity (residual stress distribution and surface topography) in orthogonal machining of Inconel718

Fires in waste facilities : Challenges and solutions from a Scandinavian perspective

Fires in waste facilities represent significant potential social, economic and environmental challenges. Although the awareness of fires in waste facilities and their consequences has increased in recent years, significant fire safety challenges remain. Fires in waste facilities in Norway and Sweden have been studied to make an overall fire safety assessment and propose measures for increased fire

Forest clear-cuts as habitat for farmland birds and butterflies

The intensification of agriculture has resulted in more homogeneous landscapes and declines of many species associated with farmland or other semi-natural open habitats. In parallel, forestry has also intensified causing declines in many species associated with old-growth forests. While intensive forestry negatively affects forest species, it inadvertently creates new habitats such as clear-cuts,

Hierarchical growing grid networks for skeleton based action recognition

In this paper, a novel cognitive architecture for action recognition is developed by applying layers of growing grid neural networks. Using these layers makes the system capable of automatically arranging its representational structure. In addition to the expansion of the neural map during the growth phase, the system is provided with a prior knowledge of the input space, which increases the proce

Three-dimensional architecture of human diabetic peripheral nerves revealed by X-ray phase contrast holographic nanotomography

A deeper knowledge of the architecture of the peripheral nerve with three-dimensional (3D) imaging of the nerve tissue at the sub-cellular scale may contribute to unravel the pathophysiology of neuropathy. Here we demonstrate the feasibility of X-ray phase contrast holographic nanotomography to enable 3D imaging of nerves at high resolution, while covering a relatively large tissue volume. We show

Behavioural responses to co-occurring threats of predation and ultraviolet radiation in Daphnia

Organisms in the wild are faced with multiple threats and a common response is a change in behaviour. To disentangle responses to several threats, we exposed two differently sized species of the freshwater invertebrate Daphnia to solar ultraviolet radiation (UVR) and predation from either moving pelagic or benthic ambush predators. Using an advanced nanotechnology-based method, we tracked the thre

Physics opportunities with the Advanced Gamma Tracking Array: AGATA

New physics opportunities are opening up by the Advanced Gamma Tracking Array, AGATA, as it evolves to the full 4π instrument. AGATA is a high-resolution γ-ray spectrometer, solely built from highly segmented high-purity Ge detectors, capable of measuring γ rays from a few tens of keV to beyond 10 MeV, with unprecedented efficiency, excellent position resolution for individual γ-ray interactions,

Combining results from hip impingement and range of motion tests can increase diagnostic accuracy in patients with FAI syndrome

Purpose: Clinical examination is an important part in the diagnosis of femoroacetabular impingement (FAI) syndrome. However, knowledge on reliability and validity of clinical diagnostic tests is scarce. The aims were to evaluate the inter-rater agreement and diagnostic accuracy of clinical tests to detect patients with FAI syndrome. Methods: Eighty-one patients (49% women) were recruited. Two expe

The rearing environment and the risk for alcohol use disorder : A Swedish national high-risk home-reared v. adopted co-sibling control study

Background: Although alcohol use disorder (AUD) runs strongly within families, studies examining the impact of rearing environment, unconfounded by genetic effects, are rare and, to date, contradictory. We here seek to conduct such a study using an adoptive co-sib control design. Methods: Defining high-risk as having 3/41 biological parent with an externalizing syndrome (AUD, drug abuse or crime),

Controlling the morphology of microgels by ionic stimuli

Stimuli-responsive microgels have attracted much interest for their use as vehicles for drug delivery or as the building blocks of adaptive materials. Ionic microgel particles, including popular poly(NIPAM-co-acrylic acid), show strong mechanical responsiveness to many external stimuli, including changes in ionic strength or acidity. In this work, we demonstrate that combining multiple ionic stimu

Phase field modelling allotropic transformation of solid solution

Based on the multiphase field conception and integrated with the idea of vector valued phase fields, a phase field model for typical allotropic transformation of solid solution is proposed. The model takes the non-uniform distribution of grain boundaries of the parent phase and the crystal orientation into account, as illustrated in simulations of austenite to ferrite transformation in low carbon Based on multiphase field conception and integrated with the idea of vectorvalued phase field, a phase field model for typical allotropic transformation of solid solution is proposed. The model takes the non-uniform distribution of grain boundaries of parent phase and crystal orientation into account in proper way, as being illustrated by the simulation of austenite to ferrite transformation in lo

Synthetic receptor analogues: preparation and calculated conformations of the 2-deoxy, 6-O-methyl, 6-deoxy, and 6-deoxy-6-fluoro derivatives of methyl 4-O-α-D-galactopyranosyl-β-D-galactopyranoside (methyl β-D-galabioside)

The 2-deoxy (7), 6-O-methyl (15), 6-deoxy (22), and 6-deoxy-6-fluoro (31) derivatives of methyl β-d-galabioside (1) have been synthesised. Thus, 7 was prepared by xanthate reduction using tributyltin hydride, whereas 22 was obtained by catalytic hydrogenation of a 6-deoxy-6-iodogalabioside.
