This work focuses into the combustion behaviour of single wheat straw particles with the aim of providing a quantitative description of the particle burning process from ignition to the early stages of the char oxidation. The single particles, in the size range 224–250 µm, were injected upward into a confined region with hot combustion products, produced by a flat flame McKenna burner, with a mean
A counter-flow reactor setup was designed to investigate the gas-phase sulfation and homogeneous nucleation of potassium salts. Gaseous KOH and KCl were introduced into the post-flame zone of a laminar flat flame. The hot flame products mixed in the counter-flow with cold N2, with or without addition of SO2. The aerosols formed in the flow were detected through Mie scattering of a 355 nm laser bea
Starch has undisputable importance in foods both from the nutritional—mainly energy—related‐and technological viewpoints. Different types of starch derivatives, including a number of hydrolysis products, are frequently used as food ingredients, especially because of the particular physicochemical properties they may confer. In recent years, certain hydrolytic derivatives of starch, such as maltode
Carbapenem resistance caused by metallo-β-lactamases is a serious global challenge that, if not tackled efficiently, is expected to lead to millions of deaths in the coming decades. Verona-integron encoded metallo-β-lactamase 2 (VIM-2) is a bacterial enzyme that has been reported from multidrug-resistant nosocomial isolates of Pseudomonas aeruginosa and other Gram-negative pathogens. As it hydroly
Under andra världskriget fälldes tusentals ton bomber mot både militära och civila mål på marken. Förlusterna var stora såväl vad gäller antal nedskjuta bombplan och omkomna besättningsmän på dessa plan som de som blev offer för bombraiderna. Historien om bombkriget sträcker sig längre tillbaka än andra världskriget, men under åren 1939–45 förändrades förutsättningarna. Bombplanen kunde medföra al
This chapter outlines the architectural approach to researching digital politics. An architectural approach focuses on platform structures and how they mediate, and can actively affect, users’ political agency online and offline. I first chart the lineage of architectural approaches in the social sciences, from discourse architectures to digital architectures. Then, I describe the process of ‘mapp
När röken klarnar blir silhuetterna av Irans ambitiösa geopolitiska strävanden mer urskiljbara, skriver Ardavan M. Khoshnood, docent, överläkare och lektor vid Lunds universitet.The orchestrated attack by Hamas on Israel on October 7, 2023, highlights a significant intelligence failure and the menacing influence of the Islamic regime in Iran. Post-attack, the regime's involvement in aiding Hamas has been echoed globally. The Islamic regime, known for supporting terrorist groups like Hamas, has been a major destabilizing force in the Middle East since 1979. The nature of t

With the rapid advancement of autonomous vehicle technology, integrating mixed autonomous and non-autonomous vehicles that are not cooperative in vehicular network has become a significant challenge. This paper presents an innovative Autonomous Intersection Management (AIM) system designed to optimize traffic flow and enhance intersection safety in such mixed traffic scenarios. By utilizing vehicl
Connected Autonomous Vehicles (AVs) have the potential to revolutionize Intelligent Transportation Systems (ITS) by addressing urban transport challenges, such asAutonomous Intersection Management (AIM). However, the assumption of highly accurate positioning in most ITS applications does not align with real-life situations. While extensive research has been conducted to improve positioning accurac
Introduction: Scale insects (Hemiptera: Coccomorpha) feed on a wide variety of agricultural crops and forest and ornamental trees worldwide. These pest insects damage plants not only by causing sap loss but also by reducing the plant's photosynthetic activity. This is because the honeydew they produce acts as a substrate for mold, which covers leaf surfaces. In the last decades, several outbreaks
Background: Pulmonary hypertension (PH) is diagnosed based on an invasive evaluation of the mean pulmonary artery (PA) pressure. The morphological assessment of the pulmonary arteries was only recently not feasible. With the advent of optical coherence tomography (OCT)-imaging, an accessible tool allows to study PA morphology longitudinally. The primary hypothesis was that OCT distincts the PA str
