Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives.

Background: Production of second-generation bioethanol and other bulk chemicals by yeast fermentation requirescells that tolerate inhibitory lignocellulosic compounds at low pH. Saccharomyces cerevisiae displays high plasticitywith regard to inhibitor tolerance, and adaptation of cell populations to process conditions is essential for reachingefficient and robust fermentations.Results: In this stu

Risk factors for suicidal behaviour include adverse life events as well as biochemical parameters acting, e.g. within the hypothalamic-pituitary-adrenal axis and/or monoaminergic systems. The aim of the present investigation was to study stressful life events and biological stress markers among former psychiatric inpatients, who were followed up 12 years after an index suicide attempt. At the time

Enterohemorrhagic Escherichia coli (EHEC) infection leads to marked intestinal injury. Sigmoid colon obtained from two children during EHEC infection exhibited abundant TUNEL-positive cells. To define which bacterial virulence factors contribute to intestinal injury the presence of Shiga toxin-2 (Stx2), intimin and the type III secretion system were correlated with symptoms and intestinal damage.

The self-diffusion coefficients of water in casein solutions and gels were measured using a pulsed-gradient spin-echo nuclear magnetic resonance technique (PGSE NMR). The dependence of the self-diffusion coefficient of water on the concentration and structure-of casein is reported. The results were analyzed using a cell model. It was found that the water self-diffusion coefficient is insensitive t

ELT science drivers stress aperture, Strehl ratio, PSF definition and stability, field of view, wavelength range, flexibility, low polarisation and thermal emittance, auxiliary instruments, site and infrastructure. Applicable science categories are planets and planetary systems, stars and stellar systems, galaxies and galaxy clusters, and cosmology. ELT observations are needed for our own and othe

Using a dislocation simulation approach, the basic equation for a crack perpendicular to a bimaterial interface is formulated in this paper. A novel expansion method is proposed for solving the problem. The complete solution for the problem, including the T stress ahead of the crack tip and the stress intensity factors are presented. The stress field characteristics are analyzed in detail. It is f

I den här studien används extremvärdesanalys för att beräkna våguppspolning och årlig dynerosion med 10, 50, och 100 års återkomsttid. Frekvensanalysen baseras på en 40 år lång tidsserie med simulerad dynerosion och våguppspolning från Ängelholms strand i Skälderviken. Med SMB-metoden beräknas vågor ute till havs som sedan transformeras till kustnära vågor i vågmodellen SWAN. Våguppspolningen berä

Pollutant transport in the unsaturated soil zone is a potential threat to surface and ground water resources. The intensity and volume of rainfall are the parameters that decide how fast and deep the pollutants will be transported. Climate models predict a future rainfall climate with higher total volume and higher intensities. In the present study we try to assess effects on unsaturated solute tr

For many applications, including future giant telescopes, there is increased interest in structural cables. Usually integrated models, i.e. combined models of structures, optics and control systems are used for modeling of telescopes. Performance of structural cables is non-linear, so often a linearization is needed to include cable models in integrated models of telescopes. We present two differe

Parasites can vary in the number of host species they infect, a trait known as “host specificity”. Here we quantify phylogenetic signal—the tendency for closely related species to resemble each other more than distantly related species—in host specificity of avian haemosporidian parasites (genera Plasmodium, Haemoproteus and Leucocytozoon) using data from MalAvi, the global avian haemosporidian da

The human genome encodes 13 aquaporin isoforms with characteristic substrate specificity that are expressed at specific locations throughout the body. Of these isoforms, AQPs 1-4 serve important functions in renal water reabsorption. Consequently, specific AQP inhibitors have been proposed as 'aquaretics', a new class of drugs suitable to induce diuresis without concomitant salt wasting. Furthermo

Purpose: The purpose of this paper is to investigate the thermal performance of the cooling plates with conventional straight channel and wavy channel designs. Design/methodology/approach: A three-dimensional model involving coupled fluid flow and heat transfer processes is developed to study the thermal performance of the cooling plates. The effects of wavelength and amplitude on the cooling perf

Inflammation has been proposed to play a role in the generation of depressive symptoms. Previously, we demonstrated that patients with major depressive disorder (MDD) have increased plasma levels of the soluble form of the urokinase receptor (suPAR), a marker for low-grade inflammation. The aim of this study was to test the hypothesis that acute exercise would induce inflammatory response characte

Enumeration of circulating tumor cells (CTCs) predicts overall survival and treatment response in metastatic cancer, but as many commercialized assays isolate CTCs positive for epithelial cell markers alone, CTCs with little or no epithelial cell adhesion molecule (EpCAM) expression stay undetected. Therefore, CTC enrichment and isolation by label-free methods based on biophysical rather than bioc
