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

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 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

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

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

TV-program på Axess i serien Luthersson läser världslitteraturen. Mortensen inbjuden gäst för samtal om den argentinska författaren Jorge Luis Borges. Programmet beständigt tillgängligt: https://www.axess.se/tv/luthersson-laser-varldslitteraturen/om-jorge-luis-borges-med-anders-mortensen/

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

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

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

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

The present study investigated sport expertise development and maintenance throng the framework of self-determination theory (SDT). In-depth semi-structured interviews were conducted with ten elite athletes who had represented their respective nations in major international events. Data were analyzed deductively according to the principles of SDT. Results indicated that sport expertise development

The authors studied gaze behaviors in high- and intermediate-skill tennis players while they performed tennis serve returns. Participants returned 40 serves in 4 serve locations while wearing a mobile eye tracker. The ball's flight path was deconstructed into 3 distinct locations (i.e., ball before bouncing on surface, the bounce area, and ball after bouncing on surface), and gaze behaviors along

INTRODUCTION: Few individuals have access to mental health services due in part to underdetection. As it is more likely to consult for medical conditions, primary care may be a useful gateway for early detection of mental health problems.OBJECTIVE: Detection of the frequency of mental health problems in four hospital services at the Fundación Santa Fe de Bogotá: Outpatient unit, hospitalization, e

A major hallmark of Alzheimer's disease is the accumulation of aggregated amyloid peptide (Aβ) in the brain. Here we develop a solubility assay for proteins and measure the solubility of Aβ40. In brief, the method utilizes 96-well filter plates to separate monomeric Aβ from aggregated Aβ, and the small species are quantified with the amine reactive dye o-phthalaldehyde (OPA). This procedure ensure

Theories of energy justice are standardly used to evaluate decision-making and policy-design related to energy infrastructure. All too rarely attention is paid to the need for a method of justifying principles of justice as well as justice-based judgments that are appealed to in this context. This article responds to this need by offering an engaged ethics approach to normative justification usefu
