Burnout resistance based on the Duration of Heating Phase concept – Literature Review and Roadmap

This study focuses on the fire behavior of structural members considering their response until the end of the fire event. The study reviews and discusses a framework for determining the burnout resistance (B) of structural members through the Duration of the Heating Phase concept (DHP). This framework complements the fire resistance rating (FRR) system by providing a rating that captures the sensi

A harmonized database of European forest simulations under climate change

Process-based forest models combine biological, physical, and chemical process understanding to simulate forest dynamics as an emergent property of the system. As such, they are valuable tools to investigate the effects of climate change on forest ecosystems. Specifically, they allow testing of hypotheses regarding long-term ecosystem dynamics and provide means to assess the impacts of climate sce

High-Quality Solution-Processed Quasi-2D Perovskite for Low-Threshold Lasers

Spin-coated quasi-two-dimensional halide perovskite films, which exhibit superior optoelectronic properties and environmental stability, have recently been extensively studied for lasers. Crystallinity is of great importance for the laser performance. Although some parameters related to the spin-coating process have been studied, the in-depth understanding and effective control of the acceleration

Forced Migrations as a European Heritage and Resource for Enhancing Intercultural Cohesion

Social identity theory argues that conflict between groups diminishes if they discover they have something important in common, and if they can build a new hybrid identity together. With this premise in mind, the article demonstrates how present-day experiences of refugees, displaced ethnic groups, political exiles, foreign-born workers, diasporic populations and other migrants may be incorporated

Softness matters : effects of compression on the behavior of adsorbed microgels at interfaces

Deformable colloids and macromolecules adsorb at interfaces as they decrease the interfacial energy between the two media. The deformability, or softness, of these particles plays a pivotal role in the properties of the interface. In this study, we employ a comprehensive in situ approach, combining neutron reflectometry with molecular dynamics simulations, to thoroughly examine the profound influe

L2 motivation and self regulated learning : An integrated model

Motivation and self-regulated learning (SRL) are interrelated constructs. Motivation can be a precursor, a mediator, and an outcome of SRL. In L2 learning, the interrelatedness of motivation and self-regulation has long been recognized (Dörnyei, 2005). However, a conceptualization of the connections is lacking. This article models the L2 motivation–SRL relationship. Drawing a distinction between p

Enclosure fire dynamics with a cross-laminated timber ceiling

An experimental study of the influence of an exposed combustible ceiling on compartment fire dynamics has been performed. The fire dynamics in compartments with combustible cross-laminated timber ceilings vs non-combustible reinforced concrete ceilings in otherwise identical compartments with three different ventilation factors were investigated. The experimental results are compared against predi

Swedish maternity care professionals’ perception of labor induction

Background: Sweden recently adopted new labor induction guidelines lowering the threshold for post-term pregnancies to 41+ weeks. Despite evidence-based foundation, these guidelines stirred controversy among maternity care professionals, who voiced concerns about potential risks and unintended consequences, such as a rising Caesarean section rate. Midwives also highlighted potential impacts on the

Pain Relieving Light - (How) Is it Possible?

About 15% of the population suffer from migraines and it is estimated that about 40% of all people with migraines would benefit from preventive treatment, but only 3-13% use it. Migraine is a huge burden for society and individuals. Migraines can be intensified by light, and some patients need to stay in a dark room until the attack is over. People with this type of photosensitivity show a clear p

Reduction of fire spalling of concrete with small doses of polypropylene fibres

The addition of polypropylene (PP) fibres has been shown to reduce the fire spalling propensity of concrete. When including this type of fibres in the concrete, the concrete mix becomes less robust, and small deviations in the constitutes change the workability and properties of the concrete. So, from a manufacturing perspective as small dosages as possible of PP fibres are desirable. Very few lar

A Methodology Using Monte-Carlo Simulation on Nanoindentation Deconvolution for Metal Classification

This paper investigates a methodology for the precise statistical deconvolution of hardness properties within various metallic matrix multiphase materials. The central focus is on accurately characterizing mechanical behaviour in the context of complex materials. To meet these objectives, we implemented an approach involving nanoindentation analyses of the selected materials. This technique allowe

PARP14 Contributes to the Development of the Tumor-Associated Macrophage Phenotype

Cancers reprogram macrophages (MΦs) to a tumor-growth-promoting TAM (tumor-associated MΦ) phenotype that is similar to the anti-inflammatory M2 phenotype. Poly(ADP-ribose) polymerase (PARP) enzymes regulate various aspects of MΦ biology, but their role in the development of TAM phenotype has not yet been investigated. Here, we show that the multispectral PARP inhibitor (PARPi) PJ34 and the PARP14

Sensing Mechanism and Excited-State Dynamics of a Widely Used Intracellular Fluorescent pH Probe : pHrodo

The pHrodo with an “off–on” response to the changes of pH has been widely used as a fluorescent pH probe for bioimaging. The fluorescence off–on mechanism is fundamentally important for its application and further development. Herein, the sensing mechanism, especially the relevant excited-state dynamics, of pHrodo is investigated by steady-state and time-resolved spectroscopy as well as quant

Constructing ZnTe Spherical Quantum Well for Efficient Light Emission

ZnTe colloidal semiconductor nanocrystals (NCs) have shown promise for light-emitting diodes (LEDs) and displays, because they are free from toxic heavy metals (Cd). However, so far, their low photoluminescence (PL) efficiency (∼30%) has hindered their applications. Herein, we devised a novel structure of ZnTe NCs with the configuration of ZnSe (core)/ZnTe (spherical quantum well, SQW)/ZnSe (shell

Midwives’ experiences of professional learning when practicing collegial midwifery assistance during the active second stage of labour : data from the oneplus trial

Background: Learning is a lifelong process and the workplace is an essential arena for professional learning. Workplace learning is particularly relevant for midwives as essential knowledge and skills are gained through clinical work. A clinical practice known as ‘Collegial Midwifery Assistance’ (CMA), which involves two midwives being present during the active second stage of labour, was found to

Exploration of anion effects in solvothermal synthesis using in situ X-ray diffraction

Solvothermal synthesis presents a facile and highly flexible approach to chemical processing and it is widely used for preparation of micro- and nanosized inorganic materials. The large number of synthesis parameters in combination with the richness of inorganic chemistry means that it is difficult to predict or design synthesis outcomes, and it is demanding to uncover the effect of different para

How do farmers adapt to water scarcity? Evidence from field experiments

This research is about how farmers adapt to water scarcity. Using experimental economics methods, field experiments were carried out in a region exposed to severe water scarcity in Colombia. Willingness of water users to cooperate in conforming to extraction caps, as a means of adapting to water availability declination was calculated. Two information treatment groups were implemented in order to

Mycobacterial regulation of macrophage responses to infection : Induction and functional role of type I interferon

Infection represents a complex interplay between invading microorganisms and the immune system. The immune system dynamically responds to the presence of pathogens, employing various defence mechanisms to neutralize and eliminate invaders. However, pathogens have evolved strategies to evade detection and elimination, leading to infections. This thesis focuses on mycobacterial regulation of macroph
