Stratification of insect diversity and daily activity patterns in the West African virgin forest Taï assessed by entomological Lidar

Lidar technology was utilized to non-destructively explore the diverse insect life in the Taï virgin forest of Côte d'Ivoire. This study employed an entomological Lidar scanned at different elevation angles, combined with traditional insect trapping at different canopy heights, to investigate the composition and spatial-temporal distribution of insects within the forest canopy. We detected stratif

Historical manufacturing census of Sweden: Data description and quality assessment

This article presents a comprehensive database featuring the digitized, cleaned, geocoded, and linked data of the Swedish manufacturing censuses between 1863 and 1900. The data covers close to the universe of Swedish manufacturing activity and includes establishment-level information on workers, the sum of production value, and toll as output value. The article describes how the data was originall

How to build (in) the future? Legitimacy of socio-technical visions in a bio-based construction sector

The use of bio-based materials offers opportunities to mitigate the climate impacts of construction, with buildings potentially acting as carbon sinks. However, it remains unclear what a future bio-based construction sector will look like. One reason for this are diverse socio-technical visions for the use of bio-based construction materials. In this paper, we use discourse analysis across a compr

When ammonia addition increases the burning velocity of a fuel blend with nitromethane

Combustion properties and combustion chemistry of ammonia (NH₃) are significantly different from those of hydrocarbons and thus require further investigation. NH₃ combustion with oxidizers different from the ambient air can reveal distinct chemistry of NOx formation, which, together with low reactivity, is one of the major obstacles in the direct deployment of ammonia as a practical fuel. In the p

Midwives’ experiences of working with menopause counselling : a qualitative study

Background: Studies have shown that women are asking for more knowledge and guidance about menopause. The professional competence of midwives encompasses menopause as a potential area of expertise. Midwives have good knowledge of women's health and are used to providing health advice. Aim: The aim was to examine midwives’ experiences of working with menopause counselling. Methods: Data were collec

Acritarch distribution in the Middle Ordovician of Öland, Sweden : Ecostratigraphical or biostratigraphical signal?

The Middle Ordovician of the palaeocontinent Baltica provides some of the best preserved and most diverse acritarch assemblages of the lower Palaeozoic. A great number of widely used acritarch genera and species have been described from this area since the 1960s and many of these taxa are considered as biostratigraphically useful for both regional and international correlation. Here, we document t

Investigating the therapeutic potential of FLASH radiotherapy – a treatment planning study

Purpose/Background: Ultra-high dose rate radiotherapy (RT) has shown potential for differential normal tissue (NT) sparing (a phenomenon termed the “FLASH effect”), particularly for larger fraction doses (>5 Gy). However, transitioning to hypofractionation may increase late-reacting NT toxicity, counteracting the FLASH effect. This study evaluates whether FLASH-RT can provide netsparing for organs

Exploring the evolution of magnesium oxidation mechanisms by density functional theory

Magnesium (Mg) is an abundant metal which has been used in aviation, medicine, hydrogen energy storage, etc. However, Mg can be rather reactive, and therefore an improved understanding of corrosion and oxidation mechanisms can enhance the efficiency of these processes to control and widen applications. The study presented here investigates the mechanisms of oxidation from the initial to full monol

Compulsions in trauma-exposed patients with obsessive-compulsive disorder : Differences in prevalence and impact on treatment response

The effectiveness of exposure and response prevention (ERP), a front-line treatment for obsessive-compulsive disorder (OCD), is contingent on reducing engagement in compulsions, though recent research has found that certain compulsions may be less amenable to ERP. Given the impact of trauma exposure on OCD compulsions, the present study sought to examine whether compulsion-specific differences in

Molecular treatments to reduce catabolic effects in human meniscus explant models

Objectives: 1. To validate catabolic meniscus explant models induced by cytokines: interleukin-6 ​+ ​interleukin-6 receptor ​+ ​tumor necrosis factor alpha (IL6/TNF) and oncostatin M ​+ ​tumor necrosis factor alpha (OSM/TNF). 2. To evaluate three potential anti-catabolic treatments: i) dexamethasone (DEX), ii) a Link-N peptide (Link-N) and iii) a peptide from chondroadherin (CKF). Design: Healthy

A lumped parameter model of the coronary circulation incorporating time-varying resistance, intramyocardial pressure and vascular compliance

Conventional lumped parameter models (LPMs) simulate coronary flow incorporating intramyocardial pressure and vascular compliance, but assuming constant resistance despite its dynamic changes during myocardial contraction. We developed a coronary LPM incorporating time-varying resistance, intramyocardial pressure and vascular compliance to simulate phasic flow, critically evaluating key contributi

Familial risks of five types of osteoarthritis in first-, second- and third-degree relatives - A nationwide Swedish family study

Objective: Osteoarthritis (OA) is a common degenerative disease with a genetic contribution. However, no large nationwide family study concerning the heredity of OA has been published. This first nationwide study aimed to determine the familial risks of the main types of OA in twins, full-siblings, half-siblings, and cousins in Sweden. Design: The Swedish Multigeneration register was linked to the

Domesticating technology : Sociotechnical imaginaries of carbon capture and storage in Denmark

Carbon capture and storage (CCS) has in recent years gained new attention in national and corporate strategies for achieving climate goals. This is for instance seen in Denmark, where CCS was positioned as the largest single mitigation tool in the 2020 Climate Programme. As an example of how international imaginaries of mitigation technologies translate into national settings, this paper explores

Surface effects in quasiatomic layer etching of silicon

The current investigation explores the surface effects of quasiatomic layer etching (Q-ALE) of silicon (Si), focusing on the interplay of process parameters, such as Ar+ ion energy, and their impact on etch rate, surface roughness, and material damage. Using a chlorine-based reactive ion etching tool at varying radio frequency bias voltages, the ion energy distribution and etching characteristics

Not for children's ears? : Parents' insights into early childhood overweight and obesity treatment

This study offers novel insights into parents' experiences of healthcare interactions during weight-related visits. Data were collected through the More and Less Europe study, a randomized controlled trial evaluating a parent support program for children (aged 2-6 years) with overweight or obesity in Sweden, Romania, and Spain to capture parents' experiences of healthcare interactions. Semi-struct

Just energy transition and gender. A systematic review for feminist research

Through a systematic review this study critically examines existing peer-reviewed evidence on the often-overlooked gender dimensions of the just energy transition. We found 52 peer-review journal papers focusing on three main themes: (1) how energy production can worsen pre-existing gender-based vulnerabilities, (2) how energy consumption can reproduce gender-based energy poverty and (3) how femin

Qualitative study of fatigue in adults with primary mitochondrial disease : Development of the PROMIS Fatigue Mitochondrial Disease Short Form

Background: Fatigue is a debilitating symptom in patients with primary mitochondrial disease nPMD). Developing new treatments that improve fatigue is a patient priority but is hampered by a lack of fit-for-purpose patient-reported outcome measures (PROMs). We aimed to understand the impact of fatigue on the lives of people with PMD and develop a brief PMD-specific PROM to evaluate fatigue in clini
