Micro- and nanostructure specific X-ray tomography reveals less matrix formation and altered collagen organization following reduced loading during Achilles tendon healing

Recovery of the collagen structure following Achilles tendon rupture is poor, resulting in a high risk for re-ruptures. The loading environment during healing affects the mechanical properties of the tendon, but the relation between loading regime and healing outcome remains unclear. This is partially due to our limited understanding regarding the effects of loading on the micro- and nanostructure

How research travels to policy: The case of Nordic peace research

How is peace research connected to practice? Observers have argued that peace research has gone from activist, political ideals about changing the world to being a methods-driven field of research that has lost all criticality. This article adds empirical substance to the debate by investigating the case of Nordic peace research and its relationship to practice. Through interview data with more th

Phase change and combustion of iron particles in premixed CH4/O2/N2 flames

Metal powder is a promising carbon-free and recyclable energy carrier. Direct combustion of the micron-sized iron particles involves complex physical and chemical processes, such as heat transfer, surface reaction, and phase change. In this work, computational modelling of these processes is investigated and validated against experiments. A single iron particle combustion and phase change model is

Systematic Development of National Guidelines for Obesity Care: the Swedish Approach

Introduction: With the rapid development of treatment modalities for obesity management, there is a growing need for guidelines. This was acknowledged by the Swedish National Board of Health and Welfare and in 2020 the process of producing the first national guidelines for obesity care, including both children and adults, was initiated. The main aim was to ensure equal high standard care throughou

Major immediate insertion-related complications after central venous catheterisation and associations with mortality, length of hospital stay, and costs : A prospective observational study

BACKGROUND: It is well-known that infectious complications after central venous catheterisation are associated with increased mortality, length of hospital stay and costs. However, there are limited data regarding such associations for immediate insertion-related complications. Therefore, the aim of this study was to investigate whether major immediate insertion-related complications are associate

A STORY ABOUT SCHIZOPHRENIA IMAGING AND METABOLISM

AbstraktNukleärmedicinska metoder vid schizofreniDen kliniska användningen av nukleära metoder startade på 1970-talet med studier av hjärnblodflödet i Lund med David Ingvars och Franzéns användning av Xenon-133 och buntar av enskilda detektorer.Införandet av SPECT med Teknetium-99m radiofarmaka som t.ex. 99mTc-HMPAO förenklade proceduren och man kunde undersöka sambanden mellan rCBF, psykopatologiAfter initial studies in the years 1960-62 in chemistry, mathematics andphysics, my scientific career in medical imaging began in 1963. My qualificationsin chemistry then came in handy when the Nordics' first gamma camera installedin Lund. Around the same time, the discovery of a radioactive isotope of a newelement Technetium-99m showed suitable for use with the gamma camera.My task became to prod

The Role of Microfibers and Liquid Aluminum in the Reaction between Boron Nitride and Tantalum Nitride

The results of thermodynamic modeling of superhard materials based on cubic boron nitride (cBN) with a tantalum nitride (TaN) binder and additions of aluminum, as well as microfibers of various physicochemical nature (oxide (Al2O3, Mg2B2O5) and non-oxide (SiC, Si3N4)), are presented. The theoretically calculated chemical interactions between the components of superhard composite materials are expe

Reaching net-zero in the chemical industry—A study of roadmaps for industrial decarbonisation

Striving to mitigate climate change, the European Union has adopted net-zero greenhouse gas emissions as a target for 2050. In this paper, European chemical industry roadmaps from the past six years are assessed and compared to uncover how the industry envisions its role in the transition to net-zero emissions. The roadmaps are assessed in terms of ambition level, technology and feedstock strategi

Ska Sverige vara ett korporativistiskt samhälle?

Jag vill undvika monopol för kollektivavtalet – eller för någon annan form av avtal, skriver Lars Jonung i ett svar på Håkan Bengtssons krönika.Hur ska den svenska modellen se ut? Ska den vara en korporativistisk modell där organiserade särintressen, parterna med andra ord, i kollektiva förhandlingar bestämmer hyror och löner för sina medlemmar? Eller ska det vara en liberal modell där rätten att

The ABC of happiness : Validation of the tridimensional model of subjective well-being (affect, cognition, and behavior) using Bifactor Polytomous Multidimensional Item Response Theory

Background: Happiness is often conceptualized as subjective well-being, which comprises people's evaluations of emotional experiences (i.e., the affective dimension: positive and negative feelings and emotions) and judgements of a self-imposed ideal (i.e., the cognitive dimension: life satisfaction). Recent research has established these two dimensions as primary parts of a higher order factor. Ho

Perceptual-Cognitive Processes in Basketball—Individual and Team Aspects

The role of psychological processes in team sports has been studied extensively. The chapter focuses on the psychological factors that are unique to basketball. These factors include the following: (a) free throw shooting—examining the role of gaze behavior in enhancing shooting percentages, (b) “the hot hand”—the underlying mechanisms leading to a “hot streak,” (c) clutch performance under pressu

3D technology of Sony Bloggie has no advantage in decision-making of tennis serve direction : A randomized placebo-controlled study

This study aimed at exploring whether 3D technology enhances tennis decision-making under the conceptual framework of human performance model. A 3 (skill-level: varsity, club, recreational) × 3 (experimental condition: placebo, weak 3D [W3D], strong 3D [S3D]) between-participant design was used. Allocated to experimental conditions by a skill-level stratified randomization, 105 tennis players judg

Quiet eye and performance in sport : A meta-analysis

Research linking the "quiet eye" (QE) period to subsequent performance has not been systematically synthesized. In this paper we review the literature on the link between the two through nonintervention (Synthesis 1) and intervention (Synthesis 2) studies. In the first synthesis, 27 studies with 38 effect sizes resulted in a large mean effect (d = 1.04) reflecting differences between experts' and
