Stable oxygen and carbon isotopes of carbonates in lake sediments as a paleoflood proxy

Lake sediments are increasingly explored as reliable paleoflood archives. In addition to established flood proxies including detrital layer thickness, chemical composition, and grain size, we explore stable oxygen and carbon isotope data as paleoflood proxies for lakes in catchments with carbonate bedrock geology. In a case study from Lake Mondsee (Austria), we integrate high-resolution sediment t

Perceptions of resilience to climate-induced disasters in Mbale municipality in Uganda

Resilience has been raised as a core task within disaster risk reduction frameworks, yet it remains difficult to implement these global ideas in local communities. This study used Community Based Resilience Analysis Approach to investigate the components that are perceived as important in resilience and the extent to which these components have been achieved. It explored the trend of resilience an

Wing morphology of the butterfly Coenonympha arcania in Europe : Traces of both historical isolation in glacial refugia and current adaptation

In this study, we examined the evolutionary outcome of and interplay between historic isolation and current selection pressures on traits more or less closely connected to fitness in the Pearly Heath butterfly (Coenonympha arcania) across its range in Europe. We hypothesized that a trait mean is more related to historic events if it has low connection to fitness, while a trait more closely connect

Guidelines of the international writing group on the diabetic foot on diagnosis

The International Working Group on the Diabetic Foot (IWGDF) has published evidence-based guidelines on the prevention and management of diabetic foot disease since 1999. This guideline is on the diagnosis, prognosis, and management of peripheral artery disease (PAD) in patients with foot ulcers and diabetes and updates the previous IWGDF Guideline. Up to 50% of patients with diabetes and foot ulc

Particle swarm optimization for micro-grid power management and load scheduling

A smart power management strategy is needed to economically manage local production and consumption while maintaining the balance between supply and demand. Finding the best-distributed generators’ set-points and the best city demand scheduling can lead to moderate and judicious use out of critical moments without compromising smart city residents’ comfort. This paper aimed at applying the Particl

Biases in radiocarbon dating of organic fractions in sediments from meromictic and seasonally hypoxic lakes

We present here radiocarbon dating results from two boreal lakes in Finland, which are permanently (meromictic) or seasonally stratified and contain continuous sequences of annually laminated sediments that started to form in the early Holocene. The radiocarbon dating results of different organic components were compared with the varve-based sediment chronologies. The deviation between the Lake Va

Lubrication characteristics of wax esters from oils produced by a genetically-enhanced oilseed crop

In this study, purified by a newly developed method Crambe (Crambe abyssinica) oil wax esters were mixed with conventional Crambe oil to examine the lubrication characteristics of bio-based wax esters and their blends. The Quartz Crystal Microbalance (QCM) results indicate high thermal stability of wax esters and their mixtures which is further supported by observed small viscosity change with tem

The dot-compartment revealed? Diffusion MRI with ultra-strong gradients and spherical tensor encoding in the living human brain

The so-called “dot-compartment” is conjectured in diffusion MRI to represent small spherical spaces, such as cell bodies, in which the diffusion is restricted in all directions. Previous investigations inferred its existence from data acquired with directional diffusion encoding which does not permit a straightforward separation of signals from ‘sticks’ (axons) and signals from ‘dots’. Here we com

In the recent Regards Photographiques judgement, the European Court of Justice held that member states cannot limit the reduced value added tax (VAT) rate to artistic photographs. In this article the judgement is analysed and discussed, also in connection with previous case law on Customs law. Also, it is discussed whether this judgement would oblige the Netherlands to apply the reduced VAT rate t

Highly viscoelastic films at the water/air interface : α-Cyclodextrin with anionic surfactants

This work showcases the remarkable viscoelasticity of films consisting of α-cyclodextrin (α-CD) and anionic surfactants (S) at the water/air interface, the magnitude of which has not been observed in similar systems. The anionic surfactants employed are sodium salts of a homologous series of n-alkylsulfates (n = 8–14) and of dodecylsulfonate. Our hypothesis was that the very high viscoelasticity c

A clinical diagnostic algorithm for early onset cerebellar ataxia

Early onset cerebellar Ataxia (EOAc) comprises a large group of rare heterogeneous disorders. Determination of the underlying etiology can be difficult given the broad differential diagnosis and the complexity of the genotype–phenotype relationships. This may change the diagnostic work-up into a time-consuming, costly and not always rewarding task. In this overview, the Childhood Ataxia and Cerebe

Expanding the ADCY5 phenotype toward spastic paraparesis : Amutation in the M2 domain

Patients with an ADCY5 gene mutation reveal a heterogenous clinical presentation including axial hypotonia, motor milestone delay, fluctuating dyskinesias, dystonia, and/or myoclonus with episodic exacerbations during drowsiness and sleep.1,2 Phenotype-genotype correlations and somatic mosaicism are suggested to explain the wide phenotypic spectrum.1 The ADCY5 gene encodes 1 of 9 membrane-bound ad

Food safety knowledge, sources thereof and self-reported behaviour among university students in Sweden

International studies have noted shortcomings in food safety knowledge and behaviour among university students. In general students do not constitute a pronounced risk group but there are wider implications. In a foreseeable future some of them will become pregnant and a majority will be responsible for vulnerable groups in their near environment. A crucial question exists, therefore, about their

Interested, indifferent or active information avoider of climate labels: Cognitive dissonance and ascription of responsibility as motivating factors

Active avoidance of information is gaining attention in behavioral sciences, and recently also its’ relevance from an economic theory perspective. We explore motivations and policy implications of active avoidance of carbon emission information. In a stated preference survey respondents were asked to indicate if they wished to access carbon emission information (info-takers) or not (info-decliners

Morphological modeling of long-term inlet channel evolution with an application to the Mundaú Lagoon inlet, Brazil

In the present study, a morphological model based on the main governing processes of inlet channels was developed for application in long-term simulations, requiring minimum data on forcing and only key information on the inlet geometry. The model considers the balance between the inlet sand transport due to tides and river flows and the longshore transport due to breaking waves. The resulting equ

Gender equality in the German Geophysical Society

The German Geophysical Society (Deutsche Geophysikalische Gesellschaft, DGG) was founded in 1922 in Leipzig, Germany, on the initiative of the famous German seismologist Emil Wiechert (1861–1928), known for his fundamental work to record earthquake waves to study the earth's interior. Facing the German historical background of the early 20th century, the 24 founding members wanted to lead German g

Identification of human D lactate dehydrogenase deficiency

Phenotypic and biochemical categorization of humans with detrimental variants can provide valuable information on gene function. We illustrate this with the identification of two different homozygous variants resulting in enzymatic loss-of-function in LDHD, encoding lactate dehydrogenase D, in two unrelated patients with elevated D-lactate urinary excretion and plasma concentrations. We establish
