Additive manufacturing (AM), which was first applied for rapid prototyping, is now becoming a real option for small-batch production of final products. Further expansion of AM is closely correlated to production costs. AM can only become competitive to traditional manufacturing methods if a product is designed for AM already from the beginning as it is an expensive technology that should only be a

Osteoporosis and osteoporosis related fractures are a major health care challenge both in Sweden and globally. The cost and suffering from osteoporosis are expected to increase since the population of elderly is increasing. Bone health can be affected by altered mineral homeostasis, which in its turn can be affected by reduced kidney function. However, the course of age-related decline in kidney f

Abstract: Noradrenaline (NA) metabolism tn the neocortex and hippocampus was examined in rats atl 1, 24, and 48 h following 15 min of reversible forebrain ischemia. As assessed by the ratio of accumulated 3,4‐dihydroxyphenylalanine (DOPA) to the tissue NA level after inhibition of DOPA decarboxylase, the NA turnover rates were markedly increased (120‐148% above the control) at 1 h postischemia in

IntroductionThe implementation of welfare technologies in Swedish eldercare reflects ongoing sociotechnical transitions, which promise to optimise care practices and administrative processes. AimOur study explores how eldercare personnel interpret and ascribe meanings to welfare technologies in their everyday care work.Material and MethodsThe study draws on an empirical dataset comprising 181 phot

För en utförlig populärvetenskaplig sammanfattning, vänligen följ länken till höger på denna sidan. De svenska utbildningsmyndigheterna står inför ett seglivat problem. Lärare har under många år uttryckt missnöje över alltmer utbredda och genomgripande krav på dokumentation. En hel del dokumentation stjäl tid som annars skulle kunna läggas på elevers lärande och att utveckla undervisningen, lyder The Swedish education authorities are up against a tenacious problem. Teachers have for years expressed dissatisfaction over increasingly prolific and pervasive demands for documentation that hijacks time that could have been invested in pupils’ learning. Over the past 15 years different Swedish governments have sought to remedy this problem but to no avail. The ‘burden of documentation’, as it is

Background: The drive for home care has increasingly impacted the organization and allocation of resources within the Swedish healthcare system. Objectives: With an interest in uncovering prerequisites for palliative care, this study aimed to investigate longitudinal trends in place of death within the adult Swedish population from 2013 to 2019 and examine potential associations between place of d

Purpose of review Breathlessness is a common, distressing and limiting symptom in people with advanced disease, but is challenging to assess as the symptom intensity depends on the level of exertion (symptom stimulus) during the assessment. This review outlines how to use recently developed normative reference equations to evaluate breathlessness responses, accounting for level of exertion, for va

Structural maintenance of chromosome (SMC) complexes organize and regulate genomes via DNA loop extrusion. During this process, the complexes increase the loop size by reeling in DNA from one or both sides of the loop. The factors governing this symmetry remain unclear. Here, we combine single-molecule analysis and molecular dynamic simulations to investigate the symmetry of loop extrusion of vari

Introduction: Home oxygen therapy is one of the few interventions that can improve survival in patients with chronic obstructive pulmonary disease (COPD) when administered appropriately, although it may cause side effects and be an unnecessary burden for some patients. Areas covered: This narrative review summarizes the current literature on the assessment of hypoxemia, different types of home oxy

Background: COPD management is guided by the respiratory symptom burden, assessed using the modified Medical Research Council (mMRC) scale, the COPD Assessment Test (CAT), or both. Research Question: What are the abilities of mMRC and CAT to detect abnormally high exertional breathlessness on incremental cardiopulmonary cycle exercise testing (CPET) in people with COPD? Study Design and Methods: A

BACKGROUND: Long-term oxygen therapy (LTOT) improves survival in patients with chronic severe resting hypoxaemia, but effects on hospitalisation are unknown. This study evaluated the potential impact of starting LTOT on acute exacerbation and hospital burden in patients with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) and pulmonary hypertension (PH).METHODS: Longi

Background: Recent declines of honeybees and simplifications of wild bee communities, at least partly attributed to changes of agricultural landscapes, have worried both the public and the scientific community. To understand how wild and managed bees respond to landscape structure it is essential to investigate their spatial use of foraging habitats. However, such studies are challenging since the

We demonstrate that exceptional points exist in fully transparent, optically "effectively" biaxial, anisotropic micro-cavities, fabricated using an uniaxial cavity material with its axis inclined to the Bragg mirror growth direction. This is similar to the existence of singular (optic) axes in absorbing biaxial crystals, but the lack of time reversal symmetry is mediated by the mode broadening, i.

Background: Home oxygen therapy (HOT) improves survival in patients with hypoxaemic chronic respiratory disease. Most patients evaluated for HOT are former or active smokers. Oxygen accelerates combustion and smoking may increase the risk of burn injuries and fire hazards; therefore, it is considered a contraindication for HOT in many countries. However, there is variability in the practices and p

X-ray phase-contrast imaging by grating interferometry has in the past decades been established both at synchrotron radiation sources and at conventional x-ray tubes. Due to the sensitivity to x-ray phase shifting, contrast in soft tissue has been improved significantly and the possibilities to do virtual histology of tissue biopsies are being pioneered. Constraints in the design of a grating inte

This paper focuses on the intersection of social dynamics, knowledge production, and the implementation of identity features in robotic platforms. Concentrating on the concept of epistemic injustice, particularly in the context of trust, the study highlights the potential for justified distrust based on experienced injustice. The incorporation of social identity features, such as gender, signals g

Microbicides in the leather industries are employed to avoid the biodeterioration of the hides by microorganisms. This problem may lead to harmful characteristics to the end product such as stains, roughness and decrease mechanical properties of leather. Therefore, microbicides like the 2-(thiocyanomethylthio) benzothiazole (TMCTB) are applied in distinct steps of the tanning process as alternativ

Grief is a normal reaction after the death of a loved one. Death rituals are an integral part of the mourning processes. Not being able to carry out death rituals can affect relatives' quality of life. The aim was to evaluate death rituals during COVID-19 and their association with relatives' quality of life. In a Swedish nation-wide study relatives to persons who died during the COVID-19-pandemic
