Shared space: utifrån bilisters perspektiv

Shared spaces är tänkta att inbjuda till ett levande stadsrum för alla samtidigt som trafiksäkerheten säkerställs genom att den traditionella uppdelningen mellan oskyddade och skyddade trafikanter tas bort. Tanken är att borttagandet av den traditionella uppdelningen ska skapa en viss osäkerhet som i sin tur ska bidra till större försiktighet. Syftet med detta projekt var därför att undersöka bili

Hydro-meteorological droughts across the Baltic Region : The role of the accumulation periods

Based on the physical and geographical conditions, the Baltic Region is categorised as a humid climate zone. This means that, there is usually more precipitation than evaporation throughout the year, suggesting that droughts should not occur frequently in this region. Despite the humid climate in the region, the study focused on assessing the spatio-temporal patterns of droughts. The drought event

Strategy-proof allocation of objects : A characterization result

This paper considers an allocation problem with a finite number of objects and unit-demand agents. The main result is a characterization of a class of strategy-proof price mechanisms on a general domain where preferences over pairs of objects and houses are rational, monotonic, and continuous. A mechanism belongs to this class if and only if the price space is restricted in a special way and, give

IL-23 to see : Gut DCs shine bright in inductive sites

The cytokine IL-23 plays important roles in intestinal barrier protection and integrity, but is also linked to chronic inflammation. In this issue of JEM, Ohara et al. (https://doi.org/10.1084/jem.20230923) provide clarity on the much-debated question of which cells produce IL-23.

Safety and Tolerability of SGLT2 Inhibitors in Cardiac Amyloidosis—A Clinical Feasibility Study

Sodium-glucose transport protein 2 inhibitors (SGLT2i) slow the progression of renal dysfunction and improve the prognosis of patients with heart failure. Amyloidosis constitutes an important subgroup for which evidence is lacking. Amyloidotic fibrils originating from misfolded transthyretin and light chains are the causal agents in ATTR and AL amyloidosis. In these most frequent subtypes, cardiac

Regulation of photoinduced charge transfer in all-small-molecule organic solar cells through the synergistic effect of external electric field and solvent

The donor (BTR-Cl) and acceptor (BTP-FCl-FCl) have well-defined small molecule properties and excellent repeatability, and they can form charge transfer complexes with a wide spectral absorption range. Using density functional theory (DFT), we simulate the photoinduced charge transfer of bulk-heterojunction (BHJ) organic solar cell (OSC) materials modulated by the external electric field (Fext) at

Cytotoxic sesquiterpenes and diterpenes from the rhizomes of Curcuma zedoaroides Chaveer. & Tanee

A phytochemical investigation of Curcuma zedoaroides rhizomes resulted in the isolation of ten sesquiterpenes (1–10) and two diterpenes (11−12). The structure of compounds 1–12 was identified as phaeocaulisin E (1), zedoarondiol (2), isozedoarondiol (3), isoprocurcumenol (4), neoprocurcumenol (5), procurcumenol (6), 1-epi-procurcumenol (7), aerugidiol (8), curcumenol (9), curcumenone (10), curcumi

Human herpesvirus 6A and axonal injury before the clinical onset of multiple sclerosis

Recent research indicates that multiple sclerosis is preceded by a prodromal phase with elevated levels of serum neurofilament light chain (sNfL), a marker of axonal injury. The effect of environmental risk factors on the extent of axonal injury during this prodrome is unknown. Human herpesvirus 6A (HHV-6A) is associated with an increased risk of developing multiple sclerosis. The objective of thi

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
