The release of gas-phase potassium species, mainly KOH, KCl, and K atoms, from burning biomass fuels can introduce severe problems to boilers, such as fouling, slagging, and corrosion. In the present work, an optical technique combining laser-induced photofragmentation and tunable diode laser absorption spectroscopy is developed for simultaneously measuring the concentration of KOH, KCl and K atom

The use of aluminum-magnesium (Al-Mg) alloy particle as energetic additive in solid propellants was previously shown to have many advantages over pure Al particle, such as relatively low ignition temperature, high reaction rate and low particle agglomeration rate. In this paper, the combustion of Al-Mg alloy in hot H2O/O2/N2 flows was experimentally studied using wires with a diameter of 200 µm. T

Background: Leakage of fire-fighting foam from an airfield caused contamination of the drinking water supplied to a third of the population in Ronneby, resulting in very high serum levels of predominantly perfluorooctane sulfonate (PFOS) and perfluorohexane sulfonate (PFHxS). The results of studies investigating the association between exposure to perfluorinated alkyl substances (PFAS) and pregnan

Burst-mode laser systems have widely been employed in diagnostics for both reactive and non-reactive flows. Unlike the continuous pulse lasers, burst-mode lasers generate pulses in bursts lasting up to 100 ms, capable to deliver high energies up to Joules per pulse. This high energy fluency is optimal for effective wavelength conversion and tuning, enabling simultaneous measurements of various spe

Introduction eHealth, defined by WHO as: “the transfer of health resources and healthcare by electronic means” are expected to increase communication between healthcare providers and patients and increase accessibility and patient participation in healthcare. The aim of this research programme is to: 1) develop a sustainable multidisciplinary environment for advancing, evaluating, and implementing

The urban energy infrastructure is facing a rising number of challenges due to climate change and rapid urbanization. In particular, the link between urban morphology and energy systems has become increasingly crucial as cities continue to expand and become more densely populated. Achieving climate neutrality adds another layer of complexity, highlighting the need to address this relationship to d

This study aims to increase the understanding of the role of visuals in crises by examining how citizens co-construct crisis through memes and how it enables certain ways of understanding the energy crisis. Knowledge about visuals in crisis communication is much needed to meet the challenge in “the post text”, where “an online culture in which text recedes to the background, and sounds and images

In their work on moral progress, Dan Egonsson and Toni Rønnow-Rasmussen both express a worry concerning possible problems caused by value incommensurability. I show that this worry can be alleviated. This is done by explicating the structure of the concept of moral progress and the structure of value comparatives. With a better understanding of the relevant concepts, it becomes clear that value in

Proposing “sustainable meetings”: convention bureaus marketing of destinations as ethicalIn the wake of a crisis and restrictions on physical interactions, the importance of meetings is emphasized more than ever. The meetings industry has gone from unprecedented down-sizing to higher booking rates than ever, and attracting meetings is an important part of municipalities place brandingstrategies. A

This dataset features geocoding for the complete population of:Landskrona at the block-level from 1904-1967;Landskrona at the address-level from 1939-1967; andKävlinge at the block-level from 1939-1967.All these populations are part of the Scanian Economic-Demographic Database (SEDD). SEDD is a high-quality, longitudinal database that covers five Scanian parishes: Halmstad, Hög, Kågeröd, Kävlinge,

This article presents a fully integrated millimeter-wave (mmW) transceiver front end covering 24.25–29.5 GHz. It features a wideband Doherty power amplifier utilizing adaptive bias and a transmit/receive switch (TRX-switch) that has embedded low noise amplifier to antenna matching. The phase shift of 90 $^\circ$ to the Doherty auxiliary amplifier is achieved using a separate IQ-mixer w

Although developing a green supply chain is a topic of growing interest in the hotel industry, research on hospitality green supply chain management (GSCM) is limited. This study investigates the effect of internal and external measures of GSCM on environmental cost reduction, and how environmental cost reduction improves the supply chain performance with the mediating role of agility and resilien

Purpose: People are shaped holistically by dynamic and interrelated individual and social-ecological systems. This perspective has been discussed in the context of varied aspects of bilingual experiences, namely language acquisition and development. Here, we applied a Systems Framework of Bilingualism to language attitudes, which may be especially responsive to social-ecological influences. Method

Introduction: Surgeons can reduce incisional hernia formation by adhering to standardized techniques for incisional wound closure. This is often neglected by the time a long operation is to be ended and can lead to the risk of developing an incisional hernia or a wound rupture. To address this issue, a suturing machine (Suture-TOOL) was developed for swift and standardized abdominal closure. The a
