Wideband RCS reduction based on a simple chessboard metasurface

To avoid being detected by radar, it is necessary to reduce stealthy military platforms' radar cross section (RCS). The operation of overlaying the metasurface (MS) on the targets is a good solution. A simple chessboard MS structure that can achieve low RCS over a large bandwidth is proposed. Only one unit cell is used to construct the MS. First, the unit cell working in 0.5 and 1−λ modes is desig

Moral Elites in the Danish Temperance Movement (1910–1919) : Elite Struggles over Disease and Values

The chapter maps out the elite of the early Danish temperance movement and shows how distinct moral elites within the movement interpreted the cause according to their respective value frames while integrating the emerging disease frame of alcoholism. Theoretically, it argues for introducing the thus far estranged perspectives of elite studies and framing approaches to each other. The concept of m

Markanvändning för en klimatpositiv framtid : En rapport om möjligheter och utmaningar i Skåne

Denna rapport är en sammanställning och analys av kunskapsläget när det gäller ekosystembaserade metoder för att minska utsläpp och öka upptag av koldioxid hos brukade marker i Skåne. Med fokus på markanvändning och skötselstrategier inom jordbruk och skogsbruk, samt användning av biokol, analyseras och bedöms potentialen för att inom Skånes gränser öka upptag respektive minska utsläpp av kol från

Dissolved Organic Matter from a colloidal perspective

Dissolved organic matter (DOM) is considered the most bioavailable fraction of soil, and thus play a key role in the cycling of carbon. Because of its mobility, DOM also forms the connection between terrestrial and aquatic systems, and constitutes an important vector for nutrients and contaminants. DOM is in this thesis operationally defined as the organic matter in an aqueous solution which is no

Detection of SARS‑CoV‑2 receptor binding domain using fluorescence probe and DNA flowers enabled by rolling circle amplification

Using rolling circle amplification (RCA) and two different ways of signal readout, we developed analytical methods to detect the receptor-binding domain (RBD) of SARS-CoV-2 spike protein (S protein). We modified streptavidin-coated magnetic beads with an aptamer of RBD through a biotin-tagged complementary DNA strand (biotin-cDNA). Binding of RBD caused the aptamer to dissociate from the biotin-cD

The Perception Divide: Exploring European and African Actors’ Views of the EU’s Climate Leadership at COP27

This study investigates the European Union’s self-perception as a global climate leader and contrasts it with the underrepresented African perspective on the EU’s role in international climate negotiations. Using a role-theoretical framework, the research analyses different leadership types and qualities, comparing European and African perceptions of the EU’s involvement in multilateral climate ch

EasyNER: A Customizable Easy-to-Use Pipeline for Deep Learning- and Dictionary-based Named Entity Recognition from Medical Text

Medical research generates a large number of publications with the PubMed database already containing >35 million research articles. Integration of the knowledge scattered across this large body of literature could provide key insights into physiological mechanisms and disease processes leading to novel medical interventions. However, it is a great challenge for researchers to utilize this informa

Occupational risk of COVID-19 in foreign-born employees in Denmark

BACKGROUND: Foreign-born workers in high-income countries experience higher rates of COVID-19 but the causes are only partially known.AIMS: To examine if the occupational risk of COVID-19 in foreign-born workers deviates from the risk in native-born employees in Denmark.METHODS: Within a registry-based cohort of all residents employed in Denmark (n = 2 451 542), we identified four-digit DISCO-08 o

Features and Bugs in Schnieder’s Theory of Properties

Although Benjamin Schnieder’s theory of the “ordinary conception” of properties successfully handles paradoxical properties—particularly, the property of non-self-instantiation—it fails to account for ordinary, non-pathological cases. The theory allows the inference of ‘a has the property of being F’ only given F(a) and the prior assertibility of ‘the property of being F can exist’. While this all

Engaging the missing actor : lessons learned from an age-management intervention targeting line managers and their HR partners

Purpose – This study aims to describe and evaluate the impact of a participatory age-management intervention on the knowledge, awareness and engagement of line managers and their HR partners from six health-care organizations in Sweden.Design/methodology/approach – The learning workshops consisted of lectures, discussions, feedback and exchange of experiences with colleagues and invited experts. A

CSF tau phosphorylation occupancies at T217 and T205 represent improved biomarkers of amyloid and tau pathology in Alzheimer’s disease

Cerebrospinal fluid (CSF) amyloid-β peptide (Aβ)42/Aβ40 and the concentration of tau phosphorylated at site 181 (p-tau181) are well-established biomarkers of Alzheimer’s disease (AD). The present study used mass spectrometry to measure concentrations of nine phosphorylated and five nonphosphorylated tau species and phosphorylation occupancies (percentage phosphorylated/nonphosphorylated) at ten si

Developing a method to study the effect of germline variants and somatic mutations in breast cancer patients on mRNA splicing

Analysis of alternative splicing has provided valuable information for multiple types of cancer, including breast cancer in recent years. Alternative splicing has been suggested to be one of the hallmarks for cancer, as dysregulation of the normal splicing process governs many aspects of cancer cell biology. For several genes previously associated with cancer, specific variants and their effect on

Air pollution in Europe and children’s health

Children are unable to choose their environment and cannot link the sensationof illness to a specific exposure or a certain environment, thus they are powerlessto remove themselves from harmful exposures. It is therefore up to us as guardians and adults to shelter them from these exposures.

Evaluation and extension of ignition delay correlations for dual-fuel operation with hydrogen or methanol in a medium speed single cylinder engine

Hydrogen (H2) and methanol (MeOH) are promising fuels for sustainable transport, owing to their ideal properties for use in internal combustion engines: CO2 neutral (when produced renewably), ultralow emissions, and high efficiencies. The dual-fuel (DF) technology where diesel is used as a pilot to ignite port fuel injected H2 or MeOH is of particular interest for retrofitting existing diesel engi

Graphs with many edge-colorings such that complete graphs are rainbow

We consider a version of the Erdős–Rothschild problem for families of graph patterns. For any fixed k≥3, let r0(k) be the largest integer such that the following holds for all 2≤r≤r0(k) and all sufficiently large n: The Turán graph Tk−1(n) is the unique n-vertex graph G with the maximum number of r-edge-colorings such that the edge set of any copy of Kk in G is rainbow. We use the regularity lemma

Using detailed milk protein composition to explain variations in rennet gelation properties

Individual milk samples were used to investigate how much of the variation in rennet gelation properties that can be explained by variation in milk composition by linear regression using the ordinary least squares method so as to optimise cheese milk. Natural variation in casein (CN) content was shown to have a large effect on gel strength but did not affect gel formation kinetics. Ionic calcium c

The Equation of Invasion Biological Invasion and the Human Measure Against it

Biological invasion is one of the main drivers of species extinctions. Therefore, measures are implemented to reduce the abundance of the invading species with the goal to mitigate its impact. These measures often lead to high labour and economic expenditures yet their effectiveness are often uncertain. To evaluate and thereby improve the mitigation of invasions, it is essential to understand the
