Gas engines (fuelled with CNG, LNG or Biogas) for generation of power and heat are, to this date, taking up larger shares of the market with respect to diesel engines. In order to meet the limit imposed by the TA-Luft regulations on stationary engines, lean combustion represents a viable solution for achieving lower emissions as well as efficiency levels comparable with diesel engines. Leaner mixt

Evaluating the optical properties of biological tissues is needed to achieve accurate dosimetry during photodynamic therapy (PDT). Currently, accurate assessment of the photosensitizer (PS) concentration by fluorescence measurements during PDT is typically hindered by the lack of information about tissue optical properties. In the present work, a hand-held fiber-optic probe instrument monitoring f

The “Woody” or “Wooden” breast disease is a severe myopathy of pectoralis major muscle recently identified within rapidly growing broiler lines all around the world with a prevalence rate around 20%, or even higher. Although of significant ethical and economic impact, little is known regarding the structural and functional aspects of the contractile apparatus in the woody breast muscle. The aim of

Online learning has become an increasingly expected and popular component for education of the modern-day adult learner, including the medical provider. In light of the recent coronavirus pandemic, there has never been more urgency to establish opportunities for supplemental online learning. Heart University aims to be "the go-to online resource" for e-learning in CHD and paediatric-acquired heart

Atmospheric carbon dioxide enrichment (eCO2) can enhance plant carbon uptake and growth1–5, thereby providing an important negative feedback to climate change by slowing the rate of increase of the atmospheric CO2 concentration6. Although evidence gathered from young aggrading forests has generally indicated a strong CO2 fertilization effect on biomass growth3–5, it is unclear whether mature fores

Et segment af danske muslimer med rødder i lande, der anvender islamisk lov, anser den islamiske vielse (nikah) og den borgerlige vielse for at være to separate vielser, der kræver to separate skilsmisser. I den forbindelse anses Familieretshusets domsmyndighed for utilstrækkelig i forhold til at opløse nikahen, eftersom en nikah-opløsning ifølge nogle muslimer kun kan foretages af en islamisk dom

The aim of the article is to present a model of causal relations that is based on what is known about human causal reasoning and that forms guidelines for implementations in robots. I argue for two theses concerning human cognition. The first is that human causal cognition, in contrast to that of other animals, is based on the understanding of the forces that are involved. The second thesis is tha

Long-term changes in terrestrial organic matter input into lakes responding to land use changes.

Based on a unique set of three drill cores, we characterize the quantity, origin and degradation state of organic matter through the subsea permafrost with higher resolution across the current thaw front, to improve our understanding of its vulnerability to decomposition upon thaw.

In this article we analyse the legal approach and measures implemented as a response to the COVID-19 pandemic implemented by Sweden’s public authorities and their legal background. Further, we discuss general legal and ethical questions related to measures to contain public health threats such as the current COVID-19 pandemic. It is outside of the scope of this paper to compare and critically anal

Background: The estrogen receptor (ER) can change expression between primary tumor (PT) and distant metastasis (DM) in breast cancer. A tissue biopsy reflects a momentary state at one location, whereas circulating tumor cells (CTCs) reflect real-time tumor progression. We evaluated ER-status during tumor progression from PT to DM and CTCs, and related the ER-status of CTCs to prognosis. Methods: I

Indebtedness is associated with poor health outcomes, and problem gambling may contribute to indebtedness through consumer credits related to gambling expenses. The assessment of consumers’ applications for loans may be an opportunity to detect and prevent further problem gambling. The present study analyzed a number of variables including gambling-related transactions and their association with p

The measurement of human vital signs is a highly important task in a variety of environments and applications. Most notably, the electrocardiogram (ECG) is a versatile signal that could indicate various physical and psychological conditions, from signs of life to complex mental states. The measurement of the ECG relies on electrodes attached to the skin to acquire the electrical activity of the he

Background: Diet is a determinant of gut microbiota. Both diet and gut microbiota have been linked to metabolic diseases. Objective: We aimed to examine data-driven food patterns in relation to the prevalence of prediabetes and gut microbiota composition and food pattern-associated bacteria in relation to prediabetes. Methods: Food patterns were extracted using principal component analysis in 1726

CONTEXT: The complexity of bladder cancer diagnosis and staging results in delays in definitive treatment of muscle-invasive bladder cancer by radical cystectomy. OBJECTIVE: This systematic review and meta-analyses aim to assess the impact of delays in radical cystectomy. EVIDENCE ACQUISITION: A systematic review was conducted by searching Medline and Ovid Gateway using protocol-driven search term
