Aerobic capacity related to cardiac size in young children.

Aim:Aerobic capacity, defined as peak oxygen uptake (VO2PEAK), is generally considered to be the best single marker for aerobic fitness. We assessed if VO2PEAK is related to different cardiac dimensions in healthy young children on a population base. Methods: In a cross-sectional study, 245 children (137 boys and 108 girls) aged 8-11 years, were recruited from a population based cohort. VO2PEAK (m

Rational characteristic functions and geometric infinite divisibility

Motivated by the fact that exponential and Laplace distributions have rational characteristic functions and are both geometric infinitely divisible (GID), we investigate the latter property in the context of more general probability distributions on the real line with rational characteristic functions of the form P(t)/Q (t), where P(t) = 1 + a(1)it + a(2)(it)(2) and Q (t) = 1 + b(1)it + b(2)(it)(2

Effects of diabetes definition on global surveillance of diabetes prevalence and diagnosis: a pooled analysis of 96 population-based studies with 331288 participants

Background Diabetes has been defined on the basis of different biomarkers, including fasting plasma glucose (FPG), 2-h plasma glucose in an oral glucose tolerance test (2hOGTT), and HbA(1c). We assessed the effect of different diagnostic definitions on both the population prevalence of diabetes and the classification of previously undiagnosed individuals as having diabetes versus not having diabet

Formation of carbonated apatite particles from a supersaturated inorganic blood serum model

Pathological calcification is common among for instance dialysis patients, and this causes an increase in mortality risk. An elevated serum phosphate concentration among those patients strongly correlates to this increase. In this work investigations of the conditions, composition, crystallinity and morphology of in vitro calcification are performed and related to results from in vivo studies. The

Effects of production and market factors on ethanol profitability for an integrated first and second generation ethanol plant using the whole sugarcane as feedstock

Background: Sugarcane is an attractive feedstock for ethanol production, especially if the lignocellulosic fraction can also be treated in second generation (2G) ethanol plants. However, the profitability of 2G ethanol is affected by the processing conditions, operating costs and market prices. This study focuses on the minimum ethanol selling price (MESP) and maximum profitability of ethanol prod

The effects of hyperglycaemia on thrombin-activatable fibrinolysis inhibitor

Epidemiological studies have shown a strong association between type 2 diabetes mellitus and cardiovascular diseases, and hypofibrinolysis may contribute to this phenomenon. The aim of this study was to determine the effect of hyperglycaemia on thrombin-activatable fibrinolysis inhibitor (TAR). Hyperglycaemia was mimicked in vitro by incubation of TAFI with glyceraldehyde and in vivo by hyperglyca

Prediction of flow rutting in asphalt concrete layers

This paper evaluates an approach for predicting rut formation in asphalt concrete (AC) layers. The approach is based on a linear viscoelastic model for predicting permanent vertical strain in AC layers subjected to a moving load. The input data are tyre pressure, loading speed, lateral wandering of loading wheel, shear modulus and phase angle of AC layer. The analytical approach takes into conside

Exclamatives in Scandinavian

In this article, I define exclamatives pragmatically, as a speech act which contains an assertion, and where there is a mismatch between this assertion and a presupposition. The assertion normally expresses a higher degree than expected, i.e. they are scalar. The speech act is instantiated in various ways in the Scandinavian languages. The aim of this article is to describe and characterise the sy

Exchange Rate Dynamics Revisited: A Panel Data Test of the Fractional Integration Order

We test the possibility that exchange rates from nine developed countries have a unit root against the alternate possibility that they are fractionally integrated. Theoretically, exchange rates are only expected to follow a random walk under restrictive assumptions. However, most traditional unit root tests cannot reject a unit root in exchange rates, and time series tests that allow for fractiona

Acute pancreatitis, from local defense to remote organ injury

Acute pancreatitis (AP) is an inflammatory disease of the pancreas. Acute abdominal pain is the most common symptom. Pancreatic injury is mild in 80% of patients, who recover without complications. The remaining patients have a severe disease with local and systemic complications such as acute lung injury (ALI). Gallstone migration into the common bile duct and alcohol abuse are the most frequent

Microwave CMOS Beamforming Transmitters

The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes. It has resulted in higher transition frequencies and red

Short- and long-term measurements of resonance frequencies on prestressed concrete beams

Currently, no method exists for determining the prestress forces in prestressed concrete structures. According to the theory of acoustoelasticity, the modulus of elasticity of concrete is stress dependent, which means that the resonance frequency of a concrete structure also is stress dependent. In this study, both short-term and long-term measurements of the resonance frequencies of four prestres

GISCOD: General Integrated Solid Waste Co-Digestion model

This paper views waste as a resource and anaerobic digestion (AD) as an established biological process for waste treatment, methane production and energy generation. A powerful simulation tool was developed for the optimization and the assessment of co-digestion of any combination of solid waste streams. Optimization was aimed to determine the optimal ratio between different waste streams and hydr
