We provide the first dedicated laboratory study of collisions of supercooled water drops with ice particles as a secondary ice production mechanism. We experimentally investigated collisions of supercooled water drops (∼5 mm in diameter) with ice particles of a similar size (∼6 mm in diameter) placed on a glass slide at temperatures >-12 °C. Our results showed that secondary drops were generated d

There is increasing empirical support for the biodiversity and ecosystem service (ES) benefits of mixed-species production forests. However, few studies control for the spatial arrangement of the trees within mixtures to determine the influence that clustering the tree species (patch scale mixtures), versus evenly dispersing them (intimate scale mixtures), may have for biodiversity and ES outcomes

Background: Previous studies have demonstrated that low-grade red blood cell transfusions (RBC) given to septic patients are harmful. The objectives of the present study were to compare mortality and morbidity in non-septic critically ill patients who were given low-grade RBC transfusions at haemoglobin level > 70 g L–1 with patients without RBC-transfusions any of the first 5 days in intensive ca

Maps have the ability to make abstract information visible and real to their audiences. They provide humans a way to conceptualize and understand places and issues that otherwise might seem both distant and abstract. This article argues that maps influence what issues are visible and knowable and what issues are silenced and disregarded, often giving prominence to dominant understandings. As such,

Clarifiers are substances used during the winemaking process to enhance clarity and stability in the wines. The different clarifiers may alter removal capacities differently. In this study, the removal efficiency of seven common fining agents, divided into three groups (mineral clarifiers, synthetic polymeric clarifiers, and vegetable protein clarifiers), was analyzed with Asymmetrical Flow Field-

Type 2 diabetes (T2D) and non-alcoholic fatty liver disease (NAFLD) often co-occur. Defining causal pathways underlying this relationship may help optimize the prevention and treatment of both diseases. Thus, we assessed the strength and magnitude of the putative causal pathways linking dysglycemia and fatty liver, using a combination of causal inference methods.Measures of glycemia, insulin dynam

Risk assessment is a useful tool in ensuring the continuous operation of critical societal functions. It can be used on many levels of an organization or society. One way to conduct risk assessments on higher system levels is to aggregate risk information from lower-level assessments. However, the process of aggregating risk information can be complex and different strategies for such aggregation Risk assessment is a useful tool to inform decision-making when it comes to ensuring the continuous operation of critical societal functions. It can be used on many levels within an organization or on multiple societal levels. One way to conduct risk assessments on a higher system level, such as on national level, is to aggregate risk information from lower-level assessments, e.g. from the regiona

Solar-Induced Chlorophyll Fluorescence (SIF) can provide key information about the state of photosynthesis and offers the prospect of defining remote sensing-based estimation of Gross Primary Production (GPP). There is strong theoretical support for the link between SIF and GPP and this relationship has been empirically demonstrated using ground-based, airborne, and satellite-based SIF observation

The Covid-19 crisis has led to widespread impacts on society, not only in terms of high death tolls, but also in terms of cascading effects for essentially all societal sectors; especially due to all measures taken to reduce the spread of the disease. A range of actors have become involved in the response to the pandemic and to ensure appropriate actions being taken, these actors need good situatiThe Covid-19 crisis has led to widespread impacts on society, not only in terms of high death tolls, but also in terms of cascading effects for essentially all societal sectors; especially due to all measures taken to reduce the spread of the disease. A range of actors have become involved in the response to the pandemic and to ensure appropriate actions being taken, these actors need good situati

Arctic environmental change induces shifts in high-latitude plant community composition and stature with implications for Arctic carbon cycling and energy exchange. Two major components of change in high-latitude ecosystems are the advancement of trees into tundra and the increased abundance and size of shrubs. How future changes in key climatic and environmental drivers will affect distributions

This paper presents a method for municipal Risk and Vulnerability Analysis which has been developed in an action research process together with a Swedish. The method combines aspects of both conti-nuity and risk management in order to exploit their strengths and avoid their limitations. It is developed to be applicable by municipal departments, i.e. a sub-part of the municipal organisations which

In voltage- and temperature-biased coherent conductors quantum screening effects occur if the conductor's transmission is energy dependent. Here, we show that an additional ac-driven terminal can act as a probe for a direct readout of such effects, hitherto unexplored. We find that screening of charges induced by the static biases impacts already their standard linear thermoelectric response coeff

The Weak Gravity Conjecture has recently been re-formulated in terms of a particle with non-negative self-binding energy. Because of the dual conformal field theory (CFT) formulation in the anti-de Sitter space, the conformal dimension ∆(Q) of the lowest-dimension operator with charge Q under some global U(1) symmetry must be a convex function of Q. This property has been conjectured to hold for a

Fra det syriske voldskaos er der opstået en ny litterær strømning, der er kendetegnet ved at være meget sanselig og kropslig. Død, blod og afrevne lemmer er gennemgående elementer i teksterne, der beskriver, hvordan krigen besætter hverdagen og fører helt nye lugte- og sanseindtryk med sig. Teksterne er et vidnesbyrd om volden og bryder med en litterær tradition i Syrien, hvor censur og afstraffelArticle in Danish on new Syrian literature written after the militarization of the popular uprising. As a consequence of the violence and destruction, this literature is very bodily and full of sense perceptions of the new war reality. The article presents literary examples written by the Syrian poet Rasha Omran and the Syrian novelist, poet, and journalist Khalil Sweileh.

Impurities coupled to superconductors offer a controlled platform to understand the interplay between superconductivity, many-body interactions, and nonequilibrium physics. In the equilibrium situation, local interactions at the impurity induce a transition from the spin-singlet to the spin-doublet ground state, resulting in a supercurrent sign reversal (0-π transition). In this work, we apply the

BACKGROUND: Pregnancy, infancy, and childhood are sensitive windows for environmental exposures. Yet the health effects of exposure to nano- and microplastics (NMPs) remain largely uninvestigated or unknown. Although plastic chemicals are a well-established research topic, the impacts of plastic particles are unexplored, especially with regard to early life exposures.OBJECTIVES: This commentary ai

Negative health effects of exposure to particles of outdoor origin have been confirmed by epidemiological studies. In developed countries, we spend on average 65% of our time in our homes. Thus, the properties of airborne particles indoors need to be understood. The aim of this PhD thesis was to investigate the differences in physicochemical and toxicological characteristics of fine particles (PM2.5
