Spent Sulfite Liquor (SSL) from wood pulping facilities is a sugar rich effluent that can be used as feedstock for ethanol production. However, depending on the pulping process conditions, the release of monosaccharides also generates a range of compounds that negatively affect microbial fermentation. In the present study, we investigated whether endogenous yeasts in SSL-based ethanol plant could

Rayleigh streaming in a homogeneous fluid has been extensively studied, and plays an important role in the manipulation of particles in microscale acoustofluidics. In this work, the acoustic streaming is investigated in a glass-silicon microchannel as it evolves in fluids made inhomogeneous in density and compressibility (or speed of sound) by the addition of solute molecules. It is found that the

In this study a novel comparison of CFD, measured data and a ID-model is presented for a Twin-scroll turbocharger turbine stage. Both full and single admission flow divisions were taken into consideration and shown to represent "on-engine" conditions in the high and low engine rpm range respectively for a heavy-duty 6-cylinder diesel engine. With this in mind, the turbine stage was evaluated for e

Background: Atrial fibrillation (AF) is defined as an irregular supraventricular tachycardia (SVT) without p waves, with duration >30 seconds. Whether AF characteristics during short SVT episodes predict AF and stroke is not known. Objective: The purpose of this study was to determine whether irregularity and lack of p waves, alone or in combination, during short SVT episodes increase the risk of

In this paper we present numerical simulations of soil plasticity using isogeometric analysis comparing the results to the solutions from conventional finite element method. Isogeometric analysis is a numerical method that uses nonuniform rational B-splines (NURBS) as basis functions instead of the Lagrangian polynomials often used in the finite element method. These functions have a higher-order

The importance of daylight to occupants’ health and wellbeing has been extensively documented, as well as its role in reducing electric lighting use. As a result, most countries have today some form of regulatory framework, specifying minimum daylight requirements for built spaces. The present Swedish building code (BBR – BFS 2011:6) includes general recommendations for daylight provision of resid

One of the most important production processes in industry is metal cutting. If a product is not a machined metal part, it is likely that the mould, die and tools used to produce the product or parts of the product are machined. The tools, machines and time spent add to the cost of the finished product and both industry and academia spend considerable effort in increasing efficacy and minimizing t

Integration of reflective writing in the curriculum can support subject learning as well as the development of generic skills.

The early modern era sees critical changes in the relations between individual and society, home and community, self and other. The notion of privacy, both as a potential threat against communal welfare and stability, and as something worthy of protection, is gradually emerging and can be traced in politics, religious practices, ideas on family and personal relations, as well as in architecture an

Using the updated ALEPH V-. A spectral function from τ decays, we determine the lowest spectral moments of the left-right correlator and extract dynamical information on order parameters of the QCD chiral symmetry breaking. Uncertainties associated with violations of quark-hadron duality are estimated from the data, imposing all known short-distance constraints on a resonance-based parametrization

We apply the spectral density reweighting technique to the analysis of the chiral phase transition in finite-temperature lattice quantum chromodynamics (QCD) with four flavors of dynamical staggered fermions and mqa=0.025. Our simulations were performed using the hybrid Monte Carlo method for LtL3 lattices with Lt=4 and L=6, 8 and 10. We calculate partition function zeros, as well as the maxima of

We study a random surface representation of Wilson loops in Z(2) gauge theory. The weights consist of an area factor, which dominates at strong coupling, and an excluded volume factor flavouring crumpled surfaces. We examine the latter one in some detail in three as well as four dimensions by use of Monte Carlo methods. In three dimensions, the critical behaviour of the surfaces is found to be det

The interaction of bacterial pathogens with their hosts' innate immune systems can be extremely complex and is often difficult to disentangle experimentally. Using mouse models of bacterial infections, several laboratories have successfully applied genetic approaches to identify novel host genes required for innate immune defense. In addition, a variety of creative bacterial genetic schemes have b

PURPOSE: To investigate the prevalence and clinical characteristics of the Charles Bonnet Syndrome (CBS) in a group of Danish patients with neovascular age-related macular degeneration (AMD) and to study whether CBS is associated with a specific retinal morphology.METHODS: Three-hundred consecutive patients with neovascular AMD attending assessment consultations following variable series of ranibi

Introduction: Sector-wide approach, or SWAp, is an increasingly popular approach to development cooperation for many bilateral and multilateral development agencies. While much has been published about the SWAp model itself, there is still limited research conducted on how it is applied in practice. This study aims at showing how the SWAp is translated as it is adopted in different local settings
