Polysulfone ultrafiltration membranes were modified with dextran, dextran sulfate and diethylaminoethyl (DEAE) dextran. The behavior of the modified membranes towards static adsorption of bovine serum albumin (BSA) was investigated in the pH range 3-7. The modified membranes showed lower flux losses after protein adsorption than unmodified membranes. The plain dextran was considered to be the best

Introduction: Uterine artery (UtA) Doppler velocimetry changes and increased arterial stiffness are associated with preeclampsia. We aimed to investigate the relation between UtA velocimetry changes and arterial stiffness in pregnant women. Methods: Doppler velocimetry and photoplethysmographic digital pulse wave analysis (DPA) were performed in 173 pregnant women in the second or the third trimes

Purpose: The purpose of this study was to investigate differences in level of physical activity between patients who underwent revision after surgery with total hip arthroplasty and those who did not. Secondary purposes were to study if level of physical activity, frequency of physical activity, body mass index, sex or age could predict the risk of revision an to find out if patients were sufficie

Since the seriousness and urgency of climate change has surfaced during the last decade, researchers, experts, and even the pope have argued that dealing with it is a moral issue. However, emissions keep rising and it seems as if few people in the north are ready and willing to make any substantial lifestyle changes to minimize the potentially catastrophic consequences, mainly to the south. Intern

Does working time causally affect workers' health? We study this question in the context of a French reform which reduced the standard workweek from 39 to 35 hours, at constant earnings. Our empirical analysis exploits variation in the adoption of this shorter workweek across employers, which is mainly driven by institutional features of the reform and thus exogenous to workers' health. Difference

Due to political conflicts, the northern part of Cyprus is being under economical crisis. This is employed by environmental problems such as non-organised improvement of residential areas and their effects on habitat. Especially, three main cities where 75 percent of population is crowded, is seriously under the threat of sewerage problems. In this study the comparisons for available sewerage syst

Rationale, aims and objectives: The process of transferring older, vulnerable adults from an elder care facility to the hospital for medical care can be an emotionally and physically stressful experience. The recent development of modern mobile radiography may help to ease this anxiety by allowing for evaluation in the nursing home itself. Up until this point, no health economic evaluation of the

During the past decade there has been a resurgence of interest in the concept of recognition in international theory. Once the narrow concern of social theorists, the concept of recognition is nowadays invoked in at least three different senses in order to explain three different things. First, it is commonly used to explain how states and their identities are shaped by interaction, and how the mo

In the 20th century early management of acute pancreatitis often included surgical intervention, despite overwhelming mortality. The emergence of high-quality evidence (randomized controlled trials and meta-analyses) over the past two decades has notably shifted the treatment paradigm towards predominantly non-surgical management early in the course of acute pancreatitis. The present evidence-base

In 2015, the world's first self-defined feminist government was formed in Sweden with the explicit ambition of pursuing a feminist foreign policy. This essay seeks to unpack and highlight some of the substance and plausible future directions of a feminist foreign policy. The overarching ambition is three-fold: (1) to probe the normative contents of feminist foreign policy in theory and in practice

Control of heat transfer is important in wind power systems. In cold climate, the problems of icing and de-icing of the turbine blades need to be handled by efficient heat transfer technologies. Heat-generating components like electric generator, gear box, and frequency converters usually need cooling under operation by various cooling solutions such as air cooling, liquid cooling, and evaporative

We report on the fabrication and characterization of radial tunnel diodes based on InP(n+)/InGaAs(p+) core-shell nanowires, where the effect of Zn-dopant precursor flow on the electrical properties of the devices is evaluated. Selective and local etching of the InGaAs shell is employed to access the nanowire core in the contact process. Devices with an n+-p doping profile show normal diode rectifi

Mergers give acquirers control over the assets of the merged entity and give sellers control over financial assets. We propose a cross-border merger model with home biased financially constrained owners in which the subsequent investments of the buyer and the seller can be determined. We show that policies blocking foreign acquisitions to protect the domestic industry can be counterproductive. For

In-situ knowledge of the gas composition close to a catalyst is essential for a better understanding of the gas–surface interaction. With planar laser-induced fluorescence (PLIF), the gas distribution around an operating catalyst can be visualized with high spatial and temporal resolution, in a non-intrusive manner. We report on a convenient setup using a nanosecond YAG-Dye laser system together w

Objectives: We compared the effectiveness of the Gold Standard Programme (a comprehensive smoking cessation intervention commonly used in Denmark) with other face-to-face smoking cessation programmes in Denmark after implementation in real life, and we identified factors associated with successful quitting. Design: Prospective cohort study. Setting: A total of 423 smoking cessation clinics from di
