AbstractBACKGROUND/AIMS: To assess the relative influence of genetic and environmental factors on retinal arterial tortuosity and the association between tortuosity and various health indices in healthy young to middle-aged persons. METHODS: This cross-sectional study included 57 monozygotic and 52 dizygotic same-sex healthy twin pairs, aged 20 to 46 years, who were characterised by determination

Advanced 1-D models for secondary clarifiers aim to incorporate more realism by explicitly accounting for several phenomena that influence the settling process. For each of them a valid mathematical expression needs to be selected to obtain a calibrated model that can be used for operation and control. The presented work evaluates different available expressions for hinderedsettling based on long

An activated sludge process (ASP) consisting of a plug-flow reactor (PFR) and a non-ideal settler is modelled and analysed. One soluble substrate component and one particulate biomass are assumed. The biomass growth rate is described by a Monod function. The settler model includes hindered settling and compression. A model describing the steady-state behaviour of the ASP is derived which constrain

Rekonstruktion:Festen är ett labb som genomförs av grupperna Banditsagor (Malmö) och Skuggteatern (Umeå). Tillsammans undersöker de en form av scenkonst där publiken är aktörerna men inte behöver ta ansvar eller agera. Labbet pågår i en vecka och avslutas med två test i form av föreställningar. Det är dessa test som vi nu bjuder in till.Rekonstruktion:Festen är en rekonstruktion av ett fiktivt hän

A simplified activated sludge process (ASP) with one substrate and one particulate biomasscomponent has been analyzed with respect to its steady states. The ASP consists of a completelystirred biological reactor and a settler. The biomass growths according to the Monod function and the decay rate is constant. In the considered one-dimensional settler model, the biomass undergoes hindered settling

Purpose: Data on the incidence of colorectal cancer (CRC) is conflicting, and it is unknown if the incidence is constant, declining, or increasing. Proximal colon cancer is considered to be more common among older individuals, but recent data have shown that rectal cancer and distal colon cancer have been increasing in the younger population. The aim of this study was to determine the trends regar

Background: Homocysteine (Hcy) has been suggested as an independent risk factor for atherosclerosis. Apolipoprotein M (apoM) is a constituent of the HDL particles. The goal of this study was to examine the serum levels of homocysteine and apoM and to determine whether homocysteine influences apoM synthesis. Methods: Serum levels of apoM and Hcy in 17 hyperhomocysteinemia (HHcy) patients and 19 con

Background: Perioperative fluid overload has been reported to increase complications after a variety of operative procedures. This study was conducted to investigate the incidence of fluid retention after pancreatic resection and its association with postoperative complications. Methods: Data from 1174 patients undergoing pancreatoduodenectomy between 2010 and 2016 were collected from the Swedish

Purpose. To test the hypothesis that a low-dose rocuronium acts mainly by means of reducing muscular endurance rather than by reducing momentary force. Methods. In a randomized placebo-controlled double-blinded study, eight healthy volunteers were studied in two sets of experiments. In the first set, the subjects made a sustained maximum effort with the dominant hand for 80 seconds while squeezing

A method to determine the binder content in small samples of cementitious material is presented. Microstructural measurements such as sorption balance measurements or TGA (thermogravimetric analysis) require small samples; therefore cement paste is often used instead of mortar or concrete to get representative samples. However, normalizing measured results to a common basis, such as the binder con

In the 1970s, grassroots disability movements in many countries changed the thinking around disability and disability politics. Nonetheless, they were also part of larger political upheavals in the western world. How were they inspired by the socialist, feminist, and gay and lesbian movements? In addition, how did they relate to non-disabled allies? Organisations in Denmark and Sweden are investig

AbstractPURPOSE: To determine whether the presence of one or more cilioretinal arteries, a distinct element of the pattern of fundus vessels, is genetically programmed, influenced by environmental factors, or the result of random mechanisms of vascular development. METHODS: The fundi of 112 pairs of healthy monozygotic and dizygotic twins were examined using digital fundus photography and visual a

Particle-assisted III-V semiconductor nanowire growth and applications thereof have been studied extensively. However, the stability of nanowires in contact with the particle and the particle chemical composition as a function of temperature remain largely unknown. In this work, we use in situ transmission electron microscopy to investigate the interface between a Au-Ga particle and the top facet
