Benefits of Investigating the Thermal Component for Moisture Safety in Ventilated Attics

Cold ventilated attics often have mould problems in Sweden. This is valid both for old and sometimes newly built attics. Increased insulation on the attic floor is assumed to increase the problem. To investigate this, numerical 1D models like WUFI or WUFI+ are typically used. These models give results but the physical processes are not so transparent for the user due to the complex numerical techn

Prognostic imaging biomarkers for diabetic kidney disease (iBEAt): study protocol

BACKGROUND: Diabetic kidney disease (DKD) remains one of the leading causes of premature death in diabetes. DKD is classified on albuminuria and reduced kidney function (estimated glomerular filtration rate (eGFR)) but these have modest value for predicting future renal status. There is an unmet need for biomarkers that can be used in clinical settings which also improve prediction of renal declin

Trade and nationalism : Market integration in interwar Yugoslavia

This article empirically analyses the relationship between nationalism and regional economic integration in the Kingdom of Yugoslavia between the First and the Second World War. It argues that prevailing nationalism had a negative impact on the economic integration of the regions within the Kingdom and further contributed to the political disintegration of the Kingdom. The analysis implies that th

Alkaliphiles : The Emerging Biological Tools Enhancing Concrete Durability

Concrete is one of the most commonly used building materials ever used. Despite it is a very important and common construction material, concrete is very sensitive to crack formation and requires repair. A variety of chemical-based techniques and materials have been developed to repair concrete cracks. Although the use of these chemical-based repair systems are the best commercially available choi

Differentiable fixed-rank regularisation using bilinear parameterisation

Low rank structures are present in many applications of computer vision and machine learning. A popular approach consists of explicitly parameterising the set or matrices with sought rank, leading to a bilinear factorisation, reducing the problem to find the bilinear factors. While such an approach can be efficiently implemented using second-order methods, such as Levenberg-Marquardt (LM) or Varia

Low bone mineral density in adults with complex congenital heart disease

Aims: The majority of children with complex congenital heart disease (CHD) survive into adulthood due to advances in medical care. Adult patients with CHD have an increased incidence of diagnoses related to ageing such as heart failure, dementia, cancer and sarcopenia, despite a relatively low age. They also have a shorter life expectancy. It is unknown if their bone structures also show signs of

RIFM fragrance ingredient safety assessment, ethyl (E)hex-3-enoate, CAS registry number 26553-46-8

The existing information supports the use of this material as described in this safety assessment. Ethyl (E)hex-3-enoate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog methyl 3-hexenoate (CAS # 2396-78-3) show that ethyl (E)hex-3-e

Promoting nature-based solutions for climate adaptation in cities through impact assessment

Climate change is expected to be an increasingly important source of impacts on biodiversity, both directly and in combination with other activities and phenomena, such as land use change, habitat fragmentation, and biological disruption. The complexity of Biodiversity Impact Assessment under climate change is increased by the fact that the effects are difficult to generalize, given that the timin

Lessons from the Swedish experience with negative central bank rates.

Negative interest rates were once seen as impossible outside the realm of economic theory. However, several central banks have recently adopted negative policy rates. The Federal Reserve is coming under increasing pressure to follow suit in the wake of the coronavirus crisis. This paper investigates the actual effects of negative interest rates using the Swedish experience from 2015 to 2019. The S

Ensembles of ecosystem service models can improve accuracy and indicate uncertainty

Many ecosystem services (ES) models exist to support sustainable development decisions. However, most ES studies use only a single modelling framework and, because of a lack of validation data, rarely assess model accuracy for the study area. In line with other research themes which have high model uncertainty, such as climate change, ensembles of ES models may better serve decision-makers by prov

Operando time- and space-resolved high-energy X-ray diffraction measurement to understand hydrogen-microstructure interactions in duplex stainless steel

Local strain development in the microstructure of a commercial 25Cr-7Ni super duplex stainless steel was mapped using high-energy x-ray diffraction during cathodic hydrogen charging under constant uniaxial load. The infusion of hydrogen resulted in tensile strains in austenite grains, one order of magnitude larger than those in the ferrite. Most strain evolution occurred at the near-surface, with

On the reduction of negative weights in MC@NLO-type matching procedures

We show how a careful analysis of the behaviour of a parton shower Monte Carlo in the vicinity of the soft and collinear regions allows one to formulate a modified MC@NLO-matching prescription that reduces the number of negative-weight events with respect to that stemming from the standard MC@NLO procedure. As a first practical application of such a prescription, that we dub MC@NLO-∆, we have impl

Low-Power Resistive Memory Integrated on III-V Vertical Nanowire MOSFETs on Silicon

III-V vertical nanowire MOSFETs (VNW-FETs) have the potential to extend Moore’s law owing to their excellent material properties. To integrate highly scaled memory cells coupled with high performance selectors at minimal memory cell area, it is attractive to integrate low-power resistive random access memory (RRAM) cells directly on to III-V VNW-FETs. In this work, we report the experimental demon

Validation of computed tomography angiography using mean arterial pressure gradient as a reference in stented superior mesenteric artery

Purpose: The aim of this prospective study was to validate the diagnostic performance of computed tomography angiography (CTA) in endoprosthesis stenosis in the superior mesenteric artery (SMA) using mean arterial pressure (MAP) gradients during angiography as a reference method. Methods: Twenty-nine patients with mesenteric atherosclerotic disease underwent 45 paired measurements of endoprosthesi

Viable business models for city logistics : Exploring the cost structure and the economy of scale in a Swedish initiative

This paper addresses the challenge of achieving profitable city logistics initiatives. A case study examines the financial continuity of one such initiative in Sweden by exploring its cost structure, the relative importance of its revenue variables, and the variables that determine the economy of scale. The results show the potential of obtaining a viable business model and provide new insights in

Survival and prognostic factors after transplantation, resection and ablation in a national cohort of early hepatocellular carcinoma

Background: In patients with early hepatocellular cancer (HCC) and preserved liver function, the choice between transplantation, resection and ablation and which factors to consider is not obvious and guidelines differ. In this national cohort study, we aimed to compare posttreatment survival in patients fulfilling predefined criteria, and to analyse preoperative risk factors that could influence

Of pipe dreams and fossil fools : Advancing Canadian fossil fuel hegemony through the Trans Mountain pipeline

This article uses the Trans Mountain pipeline expansion project as a Canadian case study to critically examine and showcase one instance of the hegemony of fossil fuels in the era of global heating. The present Canadian federal government, under the leadership of Liberal Prime Minister Justin Trudeau, is seeking to simultaneously position itself as a global climate leader while supporting the expl
