Associations between dairy consumption and the physical function in Japanese community-dwelling older adults : The Shimane CoHRE study
Objectives: We investigated sex differences in the associations between dairy consumption and the physical function among community-dwelling older adults. Methods: Six hundred and fifty-six older adults (75.6 ± 6.4 years old) participated in this study. Dairy consumption (5-item Likert score) and the physical function (gait speed, handgrip strength, and skeletal muscle mass) were measured. The lin

Branched-gallium phosphide nanowires seeded by palladium nanoparticles
Palladium nanoparticles were produced by a chemical reagent-free and versatile method called spark ablation with control over particle size and density. These nanoparticles were used as catalytic seed particles for gallium phosphide nanowire growth by metalorganic vapour-phase epitaxy. Controlled growth of GaP nanowires using significantly small Pd nanoparticles between 10 and 40 nm diameter was a
Effects on operating costs of adjusting bus departure times during peak-hour traffic in Sweden
The cost of public transport has increased more than the supply in recent years in Sweden. One of the main cost drivers identified is peak-hour traffic. The major operating cost factors are the need for a large bus fleet for short periods during mornings and afternoons and the scheduling of drivers for shorter periods than the minimum working hour restriction. The objective of this paper is to stu
Two point four million cataract surgeries : 30 years with the Swedish National Cataract Register, 1992-2021
The present review summarizes data collected by the Swedish National Cataract Register (NCR), which by the end of 2021 contained data for more than 2.4 million cataract surgeries between 1992 and 2021. During these 30 years, the cataract surgery rate rose from 3700 to 12 800. The coverage of NCR is very high including 93% of all cataract procedures in Sweden between 2010 and 2021. Independently of
Prevalence of imbedded and ingested shot gun pellets in breeding sea ducks in the Baltic Sea—possible implications for future conservation efforts
Several sea duck species in Europe face dwindling population numbers with following increased conservation focus. Shot gun practices may put extra pressure on populations not only by direct hunting mortality but also crippling and lead poisoning from ingestion of pellets. In this study, we examined three sea duck species breeding in the Swedish Archipelago of the Baltic Sea by x-raying trapped inc
Quantification of proteomic profile changes in the hemolymph of crayfish during in vitro coagulation
Hemolymph is the circulatory fluid that fills the body cavity of crustaceans, analogous to blood in vertebrates. Hemolymph coagulation, similar to blood clotting in vertebrates, plays a crucial role in wound healing and innate immune responses. Despite extensive studies on the clotting process in crustaceans, no comparative quantitative analysis of the protein composition of non-clotted and clotte
Innovation and inter-city knowledge spillovers : Social, geographical, and technological connectedness and psychological openness
Knowledge spillovers across economic agents are central to the process of technological innovation. Yet, the mechanisms by which spillovers travel and manifest as innovation are poorly understood. To fill that gap, we study how knowledge spillovers emanating from other cities (knowledge pools) diffuse and get absorbed. We refine the notion of connectedness by comparing three mechanisms through whi
Skin permeation studies of chromium species – Evaluation of a reconstructed human epidermis model
A reconstructed human epidermis (RHE) model, the EpiDerm, was investigated and compared to human skin ex vivo regarding tissue penetration and distribution of two chromium species, relevant in both occupational and general exposure in the population. Imaging mass spectrometry was used in analysis of the sectioned tissue. The RHE model gave similar results compared to human skin ex vivo for skin pe
The Dynamic Collections : a 3D Web Platform of Archaeological Artefacts designed for Data Reuse and Deep Interaction
The Dynamic Collections project is an ongoing initiative pursued by the Visual Computing Lab ISTI-CNR in Italy and the Lund University Digital Archaeology Laboratory-DARKLab, Sweden. The aim of this project is to explore the possibilities offered by a deep, structured interaction with a large set of digital replicas of archeological artefacts. The project developed and deployed a web-based platfor
Rare-variant collapsing analyses reveal novel risk genes for arterial and venous cardiovascular diseases in the UK biobank
Developing novel diffusion MRI methods for comprehensive analysis of restricted and anisotropic self-diffusion system
Diffusion MRI is a non-invasive imaging technique used to study the microstructural properties of biological tissues by observing the self-diffusion of water molecules. Traditional diffusion MRI methods, based on the pulsed gradient spin-echo sequence, employ magnetic field gradients to encode information about translational motion. However, this approach combines various aspects of diffusion, suc
A pragmatic approach to the limitations of safety management systems in aviation
Commercial aviation systems are increasingly stretched to their capacity while existing Safety Management Systems (SMS) do not live up to our expectations as higher efficiency standards are taxing human resources, higher competition levels are reducing the potential for collaboration and the sharing of risk data, and technological advances are making systems difficult to operate and re-design. Avi
A data-driven approach for plasticity using history surrogates : Theory and application in the context of truss structures
Data-driven methods and algorithms show immense potential for future advancements in the modeling and simulation of complex mechanical systems. However, in order to actually exploit this potential, the methods must be extended to consider inelastic and path-dependent material behavior—a step that appears more complex than in conventional material modeling, where this can be achieved with the help
Drying intensity and acidity slow down microbial growth recovery after rewetting dry soils
Soil microbes perceive drying and rewetting (DRW) events as more or less harsh depending on the previous soil moisture history. If a DRW event is not perceived as harsh, microbial growth recovers rapidly after rewetting (referred to as ‘type 1’ response), while a harsh DRW will be followed by a delayed growth recovery (‘type 2’ response). Predicting these responses based on pedoclimatic factors is
Ex‐situ synchrotron X‐ray diffraction study of CO2 corrosion‐induced surface scales developed in low‐alloy steel with different initial microstructure
The CO2 corrosion-induced scale developed in the surface region of the low-grade carbon steel is thoroughly investigated to understand the corrosion mechanisms involved during exposure to CO2-saturated aqueous environments. In this work, in addition to the electron microscopy and lab-source X-ray diffraction (XRD) methods, ex-situ depth-resolved phase identification of the corrosion scales develop
The potential of salinity gradient energy based on natural and anthropogenic resources in Sweden
This paper presents assessment of natural and anthropogenic sources of blue energy within Swedish territory to identify suitable spots for implementing new projects. The natural energy potential of salinity gradients was found to be higher in southwest Sweden, and a national energy resource potential of 2610.6 MW from seawater/river water mixing will be reduced to a technical potential ranging fro
Development of a functional hardness gradient in WC-TiC-Co cemented carbide during gradient sintering
In this study two functionally graded cemented carbide samples with gradients in both composition and grain size have been produced and studied. The two samples are manufactured by local addition of TiC to a pressed WC-Co green body prior to sintering. The two samples differ only by the in-going WC particle size, where one sub-micron and one coarse WC particle size is used. The Ti, Co, and C conce
