Pervaporation offers solutions for a wide range of applications ranging from the dehydration of organic compounds to the recovery of organic compounds from water and the separation of organic mixtures. While the combination of pervaporation and distillation in a hybrid process to break azeotropes is well established on an industrial scale, successful applications of hydrophobic pervaporation are r

An online, multimedia edition of 'A Description of the Valley of Chamouni, in Savoy' (1819), by Samuel Glover. This edition brings to light a forgotten and important work of travel literature about Chamonix-Mont Blanc, and documents its close connections with the activities of Mary and Percy Shelley during to the so-called 'Frankenstein Summer' of 1816, and with high-profile exhibitions about Cham

We implemented a functional neuronal network that was able to learn and discriminate haptic features from biomimetic tactile sensor inputs using a two-layer spiking neuron model and homeostatic synaptic learning mechanism. The first order neuron model was used to emulate biological tactile afferents and the second order neuron model was used to emulate biological cuneate neurons. We have evaluated

Carrot psyllids (Trioza apicalis) pose a constant threat to carrot production in parts of Europe, and treatments with chemical insecticides are common. To be able to develop alternative control tactics, more knowledge about the psyllid's host-finding behaviour and underlying physiology is needed. Using single-sensillum recordings from overwintered and non-overwintered males and females, we found e

IntroductionAn overview of the different hybrid-processes combining pervaporation with a conventional separation as a tool to recover organic compounds from waste water will be given. Analysing potential applications shows that pervaporation alone will rarely be economical due to the purity required nowadays in waste water treatment. The limitation on flux owing to the activity being the driving

The deposition of coassemblies made of the small presynaptic protein, α-synuclein, and lipids in the brains of patients is the hallmark of Parkinson's disease. In this study, we used natural abundance 13C and 31P magic-angle spinning nuclear magnetic resonance spectroscopy together with cryo-electron microscopy and differential scanning calorimetry to characterize the fibrils formed by α-synuclein

We recruited 78 men and 94 women to investigate if the proportion of subjects with well-controlled home blood pressure levels could be increased when treatment was guided by smartphone-based telemonitoring. All patients were prescribed one to three antihypertensive drugs. The Accumbo smartphone telemonitoring application was downloaded to the Iphones of the participants and home blood pressure inf

End-use efficiency, demand response and coupling of different energy vectors are important aspects of future renewable energy systems. Growth in the number of data centres is leading to an increase in electricity demand and the emergence of a new electricity-intensive industry. Studies on data centres and energy use have so far focused mainly on energy efficiency. This paper contributes with an as

Introduction: The objective was to create a clinically useful prediction model for vaginal birth in trial of labor after one cesarean section, appropriate for a third trimester consultation. Material and methods: Women with one cesarean section and at least one following delivery (N = 38 686) in the Swedish Medical Birth Register, 1998-2013, were studied. The women were randomly divided into one d

Geosmin is one of the most recognizable and common microbial smells on the planet. Some insects, like mosquitoes, require microbial-rich environments for their progeny, whereas for other insects such microbes may prove dangerous. In the vinegar fly Drosophila melanogaster, geosmin is decoded in a remarkably precise fashion and induces aversion, presumably signaling the presence of harmful microbes

OBJECTIVE: A randomized controlled trial (RCT) was undertaken to determine the effect of negative pressure wound therapy (NPWT) on closed incisions after inguinal vascular surgery regarding surgical site infections (SSIs) and other wound complications. BACKGROUND: SSIs are a major concern in open vascular procedures involving the inguinal region. Prophylactic NPWT on closed incisions has shown pro

OBJECTIVES: To assess whether sevoflurane provides better haemodynamic stability than propofol in acute right ventricular (RV) ischaemia-reperfusion. METHODS: Open-chest pigs (mean ± standard deviation, 68.8 ± 4.2 kg) anaesthetized with sevoflurane (n = 6) or propofol (n = 6) underwent 60 min of RV free wall ischaemia and 150 min of reperfusion. Haemodynamic parameters and blood flow in the 3 majo

Human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) can be differentiated into many different cell types of the central nervous system. One challenge when using pluripotent stem cells is to develop robust and efficient differentiation protocols that result in homogenous cultures of the desired cell type. Here, we have utilized the SMAD-inhibitors SB431542 and Noggin in a
