Development and validation of the motivation for electricity saving behaviour scale (MESBS) among residents living in energy-efficient buildings in Sweden

Even though energy-efficient technologies are well developed, the behaviour of building occupants plays an important role in the search for the optimum level of energy efficiency. In academic literature, however, very few studies have used psychological theories to understand individuals’ drivers of energy use behaviour when interacting with energy-efficient technologies. Specifically, there are n

Implementing injury prevention training in youth handball (I-PROTECT) in Sweden: Study protocol for a cluster-randomized trial

Introduction Efficacy trials show that evidence-based injury prevention training reduces injuries in youth athletes but effectiveness, that is, outside the controlled setting, is lower and, consequently this training has had limited public health impact. Insufficient involvement of end-users at the individual and organisational levels is identified as a main barrier to successful implementation. T

Proof-of-concept of an ultrafast source in the Soft X-ray range

At MAX IV laboratory the linac is used to inject into the two rings but also to drive the FemtoMAX beamline, which is a source of (incoherent) short pulses in the Hard X-ray range.In this contribution we present the design and simulations for a new mode of operation of the linac that would allow to generate coherent ultra-short FEL pulses in the soft X-ray domain. Preliminary simulations indicate

Experimental investigation of single drop breakup in a confined turbulent wall-jet : Effect of Weber number

This study uses an experimental scale-up model together with a high-speed camera setup to quantitatively study the effect of Weber number on the breakup probability, deformation time, breakup time, breakup position, and breakup rate in this geometry in a turbulent jet. Results show an increase in breakup probability and a decrease in deformation and breakup times with increasing Weber number. Brea

Oxidative Stress and Its Biomarkers in Cardiovascular Diseases

Background: Cardiovascular diseases (CVDs) are the most common cause of death worldwide. CVDs share heterogeneous pathophysiologic mechanisms, one of which includes increased oxidative stress. Main Body: Surplus levels of reactive oxygen species induce damage to cellular macromolecules such as DNA, proteins, and lipids. Increased reactive oxygen species result in decreased nitric oxide availabilit

Does Fusobacterium in Colorectal Cancer Sites Originate From the Oral Cavity? A Pilot Study

Objectives: Fusobacterium can contribute to oral diseases, but also pose as a systemic risk factor. This genus, and especially F. nucleatum, can be found in colorectal cancer (CRC) tissue and is involved in multiple aspects of this type of cancer. Previous studies indicated a possible oral origin of these bacteria; however, stronger evidence is needed to reach a definitive conclusion. This pilot s

Bimodal response strategy in Daphnia to ambush predation risk

Predation's consequences can manifest through either consumptive or nonconsumptive effects, but the prey response may also vary depending on the predator hunting strategy. Considerable attention has been paid to coursing predators, whereas less information is available regarding responses to ambush predators. To remedy this paucity, we utilized a three-dimensional tracking platform to record group

Infection length and host environment influence on Plasmodium falciparum dry season reservoir

Persistence of malaria parasites in asymptomatic hosts is crucial in areas of seasonally-interrupted transmission, where P. falciparum bridges wet seasons months apart. During the dry season, infected erythrocytes exhibit extended circulation with reduced cytoadherence, increasing the risk of splenic clearance of infected cells and hindering parasitaemia increase. However, what determines parasite

Reuse of building materials : The perspective of Swedish clients

In the context of the circular economy, there is an urgent need for transformation into circular material flows by avoiding waste, reducing extraction of virgin raw materials, and extending product life cycles. Within the construction and real estate industry, the reuse of building materials stands out as a critical strategy for value retention. The objective of this paper is to localise the foref

Misconduct by private security officers and trust in the police : evidence from a natural experiment in Sweden

Previous studies have shown that police assaults reduce trust in the police among the group affected by the incidents. As the phenomenon of plural policing emerges and the actors in policing become intertwined, blurring the boundaries between them, analysis of the impact of security guards’ actions becomes warranted. This paper investigates the impact of two security guard incidents on trust in th

A dynamic humidity arena to explore humidity-related behaviours in insects

Humidity is a critical environmental factor influencing the behaviour of terrestrial organisms. Despite its significance, the neural mechanisms and behavioural algorithms governing humidity sensation remain poorly understood. Here, we introduce a dynamic humidity arena that measures the displacement and walking speed of insects responding to real-time changes in relative humidity (RH). This arena

Därför blomstrar det statslösa språket

Berättelsen om Katalonien har under senare år handlat om försöken att bryta sig loss från Spanien. Men vid sidan om de politiska slitningarna har regionens litteratur fått stort genomslag, inte minst genom den katalanskspråkiga författaren Irene Solà. Kanske närmar vi oss en ny renaixença?

The genus Siderus (Lepidoptera: Lycaenidae) in French Guiana : four newly discovered species and conspicuous male genitalia polymorphism

The species of Siderus Kaye present in French Guiana are listed and detailed with notes on male territorial behavior and the plants at which adults feed. In total, seven species were recorded: Siderus leucophaeus (Hübner); Siderus parvinotus Kaye (first record from French Guiana); Siderus athymbra (Hewitson); Siderus diringeri Faynel, Robbins & Fåhraeus sp. nov.; Siderus bisignatus Faynel, Ram

Resilience: why should we think with care?

Resilience has become a ubiquitous term. Individuals, communities and societies are increasingly called upon to be resilient and build resilience as a way to withstand and bounce back from compound climate-induced shocks, conflicts, health and economic crises. In this provocation we critically interrogate the potential that resilience holds for moving beyond a world marked by crises and widening i

Microheater Controlled Crystal Phase Engineering of Nanowires Using In Situ Transmission Electron Microscopy

Crystal Phase Quantum Dots (CPQDs) offer promising properties for quantum communication. How CPQDs can be formed in Au-catalyzed GaAs nanowires using different precursor flows and temperatures by in situ environmental transmission electron microscopy (ETEM) experiments is studied. A III-V gas supply system controls the precursor flow and custom-built micro electro-mechanical system (MEMS) chips wi

The CoV-Y domain of SARS-CoV-2 Nsp3 interacts with BRAP to stimulate NF-κB signaling and induce host inflammatory responses

Non-structural protein 3 (Nsp3) is the largest protein encoded by the coronavirus (CoV) genome. It consists of multiple domains that perform critical functions during the viral life cycle. CoV-Y is the most C-terminal domain of Nsp3, and it exhibits evolutionary conservation across diverse CoVs; however, the exact biological function of CoV-Y remains unclear. Here, we determined the crystal struct

High circulating activin A plasma levels are associated with tumour stage and poor survival in treatment-naive lung squamous cell cancer patients

Objectives: Lung squamous cell carcinoma (LUSC) is associated with a poor prognosis and a lack of specific treatment options. The dysregulation of activin A (ActA) has been reported in various malignancies. Herein, we investigated the diagnostic and prognostic significance of ActA in LUSC. Materials and methods: ActA concentrations were measured using ELISA in plasma samples of 128 LUSC patients (

Predator-induced defense decreases growth rate and photoprotective capacity in a nitrogen-limited dinoflagellate, Alexandrium minutum

Some dinoflagellates produce toxic secondary metabolites that correlate with increased resistance to grazers. The allocation costs of toxin production have been repeatedly addressed, but with conflicting results. Few studies have considered the potential costs of this defense to the photosystem, even though defense toxins (e.g., karlotoxins and brevetoxins) are closely linked to the photoprotectiv
