Ethnopharmacological relevance: The red Brazilian cherry, Eugenia uniflora, is widely used in traditional medicine. The aim of this study was to investigate the phytochemical composition of a methanol extract from leaves of E. uniflora and characterization of the isolated compounds. In addition, we aimed to determine the antioxidant activities in vitro and in a cell-based (HaCaT cell)model. We als

We investigate nonequilibrium transport of charge and heat through an interacting quantum dot coupled to a finite electron reservoir. Both the quantum dot and the finite reservoir are coupled to conventional electric contacts, i.e., infinite electron reservoirs, between which a bias voltage can be applied. We develop a phenomenological description of the system, combining a rate equation for trans

This paper critiques the assumption that capitalist agriculture inherently develops productive forces, highlighting its internal contradictions and questioning its sustainability as a viable agricultural model. Using immanent critique, the paper engages with the capitalist framework on its own terms to demonstrate how its focus on profit maximisation and short-term productivity leads to long-term

We investigate the link between the internal microstructure of poly(N-isopropylacrylamide)-poly(ethylene glycol) methyl ether methacrylate (PNIPAM-PEGMA) microgels, their bulk moduli and the rheological response and structural arrangement in dense suspensions. The low degree of crosslinking combined with the increased hydrophilicity induced by the presence of PEGMA results in a diffuse, star-like

This study explored how the Swedish Fire and Rescue Service identifies problems and implements necessary actions during complex problem-solving in emergencies, aiming to increase our understanding of this process. Primary and secondary data from large-scale fire events were analyzed, including semistructured interviews and incident reports. The concept of “possibility space” is applied to identify

As part of the project FIRE21, a workshop was organised in Trondheim on September 8, 2023, inviting all project partners (Lund University, Research Institutes of Sweden, the Technical University of Denmark and the Norwegian University of Science and Technology) to brainstorm on potential problems for the fire and rescue services (FRS) in the 21st century, and recommendations on how to improve the

Introduction: Having many melanocytic nevi on the skin is a risk factor for melanoma. However, the reproducibility of nevus counts in previous studies is limited due to high inter- and intraobserver variation. Despite the introduction of a protocol for counting and reporting of nevi in 1990 by the International Agency for Research on Cancer (IARC), significant variations in nevus counting methods

This report summarises the results from an interview and literature study carried out to identify key individual qualities for collective problem-solving in a fire and rescue service context. The report contributes to the research project FIRE21 (Fire and Rescue Services in the 21st Century) and is part of a work package looking into such individual qualities through using different methods and ma

The paper details a study that investigated dimensions of mind perception in social agents across various agent types. Factor analysis on 18 mental capacities was conducted across 12 characters, which included 9 social agents - 3 chatbots, 3 voice assistant speakers, and 3 robots. Two factors were identified that roughly aligned with task-oriented and affective-reflective cognitive processes. Base

I denna rapport sammanställer vi resultaten från två workshops som utförts som en del av projektet FIRE21 (Fire and Rescue Services in the 21st Century). I projektet studerar vi (forskare från Sverige, Norge och Danmark) hur räddningstjänster löser problem i så kallade problemlösande nätverk. Vi ser dessa som nödvändiga för att lösa problem i dagens och morgondagens insatser, där vi behöver olika

We study the problem of obtaining lower bounds for polynomial calculus (PC) and polynomial calculus resolution (PCR) on proof degree, and hence by [Impagliazzo et al.'99] also on proof size. [Alekhnovich and Razborov'03] established that if the clause-variable incidence graph of a conjunctive normal form (CNF) formula F is a good enough expander, then proving that F is unsatisfiable requires high

Chatbots designed to achieve specific goals are increasingly used in service roles. Human-like characteristics in chatbots are seen as beneficial to interaction. Given the purpose-driven nature of goal-oriented chatbots, whether humanlikess of various characteristics of these chatbots has an effect on their perception and use is unclear. This study explores the role of humanlikeness in goal-orient

Semidefinite programs are convex optimization problems involving a linear objective function and a domain of positive-semidefinite matrices. Over the past two decades, they have become an indispensable tool in quantum information science. Many otherwise intractable fundamental and applied problems can be successfully approached by means of relaxation to a semidefinite program. This methodology is

This document summarises key recommendations from project FIRE21. The recommendations are based on results from 1) professionals through the workshop with Räddningstjänsten Syd (Rsyd) and the Norwegian survey and 2) acquired experiences and knowledge from project members.

Rationale: According to the Global Initiative for Obstructive Lung Disease (GOLD), the FEV1/FVC ratio is used to confirm the presence of airflow obstruction in the diagnosis of chronic obstructive pulmonary disease (COPD), whereas FEV1 percent predicted normal value (FEV1%pred) is used for grading its severity. The STaging of Airflow obstruction by the FEV1/FVC Ratio (STAR), and its prediction of

This article describes the synthesis and characterization of novel cationic five-coordinate Pt(II) complexes containing nitrogen sugar-based ligands. The cytotoxicity of the complexes was evaluated on different cell lines with the expectation that both the coordinative saturation and the sugar moiety cooperate to enhance their biological activity. In fact, the complexes resulted to be more active

Opuntia ficus-indica L. is known for its beneficial effects on human health, but still little is known on cladodes as a potent source of antioxidants. Here, a direct, economic and safe method was set up to obtain water extracts from Opuntia ficus-indica cladodes rich in antioxidant compounds. When human keratinocytes were pre-treated with the extract before being exposed to UVA radiations, a clear
