Effective disaster risk management is a requisite for sustainable development and it is paramount to include a wide range of stakeholders to manage risk in this context. Recent research indicates the significance of making ideas of what is valuable and important to protect explicit in any disaster risk management initiative that involves several stake- holders. The purpose of this article is thus

Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and guid

Phase modulation and phase cycling schemes have been commonly used in electronic two-dimensional (2D) spectroscopy where the observables are incoherent signals such as fluorescence or photocurrent. Although the methods have distinct advantages compared to the coherent signal-detected 2D spectroscopy in sensitivity, possibility to measure spectra from isolated quantum systems and direct visualizati

Background: Circulating tumor cells (CTCs) carry independent prognostic information in patients with metastatic breast cancer (MBC) on different lines of therapy. Moreover, CTC clusters are suggested to add prognostic information to CTC enumeration alone but their significance is unknown in patients with newly diagnosed MBC. We aimed to evaluate whether longitudinal enumeration of circulating tumo

Over recent years many urban areas have experienced severe floods caused by extreme precipitation events. To avoid the devastating socioeconomic and environmental consequences of such floods, countries have issued laws or recommendations on flood risk assessment in urban planning. However, these laws or recommendations seldom include detailed requirements on input data quality or explicit instruct

Introduction: The rate of vaginal hysterectomies is declining globally. We investigated surgical techniques, outcomes, and costs in a large national cohort of benign hysterectomies with prerequisites for vaginal surgery. Material and Methods: A retrospective register-based cohort study with benign hysterectomies in the Swedish GynOp registry 2014–2023 (n = 17 804). Inclusion criteria were non-prol

With the emergence of autonomous vehicles comes the requirement of adequate and rigorous testing, particularly in critical scenarios that are both challenging and potentially hazardous. Generating synthetic simulation-based critical scenarios for testing autonomous vehicles has therefore received considerable interest, yet it is unclear how such scenarios relate to the actual crash or near-crash s

This paper presents a low-profile, single-layer, broadband, polarization-reconfigurable metasurface antenna with a low radar cross section (RCS). The design leverages characteristic mode analysis (CMA) applied to a staggered elliptical-shaped unit cell metasurface. The unique arrangement of the elliptical-shaped elements, oriented at 90°, promotes mode fusion through CMA, effectively reducing RCS.

Context. Extremely metal-poor (EMP) stars preserve a fossil record of the composition of the ISM when the Galaxy formed. It is crucial, however, to verify whether internal mixing has modified their surface composition, especially in the giants where most elements can be studied. Aims. We aim to understand the CNO abundance variations found in some, but not all EMP field giants analysed earlier. Mi

We present a comparative analysis of the unfolding and inactivation of three cutinases in the presence of guanidine hydrochloride (GdnHCl) and bis(2-ethylhexyl) sodium sulfasuccinate (AOT). Previous investigations have focused on the cutinase from Fusarium solani pisi (FsC). In addition to FsC, the present study includes the cutinase from Humicola insolens (HiC) and a mutant variant of HiC (mu HiC

Background: Existing working heart models for ex vivo functional evaluation of donor hearts often use cardiac afterloads made up of discrete resistive and compliant elements. This approach limits the practicality of independently controlling systolic and diastolic aortic pressure to safely test the heart under multiple loading conditions. We present and investigate a novel afterload concept design

Efforts to regulate transnational corporations in the context of human rights are not new. They traced back to the early 1970s, when the United Nations first initiated attempts to study the impact of transnational corporations on the international development process and proposed a United Nations Code of Conduct on Transnational Corporations, an initiative that ultimately stalled. A renewed attemp

Motivationen med studien var den alldeles för höga stråldosen som används vid CTundersökningar. I de allra flesta fallen anpassas man inte rörströmmen efter patientens storlek och därmed får smalare patienter en onödigt hög stråldos. Målet var att reducera stråldosen till patienter som undersöks med datortomografi utan att minska på bildkvalité, genom att anpassa rörströmmen efter patientens stoIn this study we have investigated the possibilities of dose reduction in CT at a constant level of image quality by adjustment of the tube current to the phantom size. The motivation with the study is the high radiation doses to the patients and the increasing frequency of CT examinations and the variety of examinations in CT, and that the same tube current is used for different patient sizes. Ac

Denna studie undersöker den politiska kampanjmetoden dörrknackning (canvassing) med syftet att få en inblick i hur dörrknackarna upplever den retoriska situationen ute i fält. Det empiriska materialet har samlats in genom tio kvalitativa forskningsintervjuer och analyserats med Lloyd F. Bitzers modell “The Rhetorical Situation” (1968). Slusatserna är att dörrknackning som metod är situationell i sThis study examines the rhetorical situation of door-to-door canvassing through qualitative research interviews with partisan canvassers from the Social Democratic Party in Malmö, Sweden, with the theoretical framework of Lloyd F. Bitzer's "The Rhetorical Situation" (1968). The study concludes that door-to-door canvassing is situational in its form, and must therefore respond to audi

Offentlig upphandling är en inköpsprocess av nyttjas av offentliga verksamheter såsom myndigheter och kommuner. Årligen spenderar Sverige ca 800 miljarder kronor via offentliga upphandlingar, vilket har en stor inverkan på miljön då dessa kontrakt ofta följer den linjära ekonomiska modellen, slit- och släng samhället. Begreppen cirkularitet och cirkulär ekonomi är relativt nya koncept som har de sThe EU procured for roughly 202000 MEUR (14% of the EU GDP) during 2021 in the public sector. The majority of these contracts are traditional, linear business model purchases. The EU has been developing several strategies, guidelines, and policies for sustainable purchasing, with Circular Public Procurement for a Circular Economy (CE) being one of them, but the implementation rate is low. Electron

Reconfigurable intelligent surface (RIS) can manipulate the electromagnetic (EM) waves in wireless channels and thus is promising for the sixth generation wireless communication systems. However, there exists little research on RIS channel measurements, which are important for the communication system design. In this paper, channel measurements are carried out in anechoic chamber, outdoor, and ind

Background: The European Union (EU) AI Act (AIA) aims to facilitate trustworthy Artificial Intelligence (AI) systems, especially for safety-critical use cases. Compliance with this new regulation entails a multitude of legal, technical, and organizational challenges for the providers of affected systems.Objective: This regulatory compliance engineering research aims for an empirical exploration an
