BackgroundCellulase enzymes have been reported to contribute with a significant share of the total costs and greenhouse gas emissions of lignocellulosic ethanol production today. A potential future alternative to purchasing enzymes from an off-site manufacturer is to integrate enzyme and ethanol production, using microorganisms and part of the lignocellulosic material as feedstock for enzymes. Thi
We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.
Electrical brain activity and eye movements were recorded in 10 intact and 6 unilaterally labyrinthectomized rabbits, each with implanted electrodes. The frequency of optokinetic nystagmus (OKN) and a 10-second aggregate of theta waves in the dorsal hippocampus were determined after exposure of the animals to sound, vibration and optokinetic stimulation. Each stimulus used caused significant incre
In this work, physical and chemical characterization of El- Lajjoun retort water from oil shale pyrolysis process has been carried out. Comparison of different treatment methods for the major components which could affect the design and operation of any set of wastewater treatment process were conducted. The removal of phenol and ammonia using activated carbon after 12 hour resident time were 93 a
Requirements engineering for commercial off-the-shelf software packages entails special challenges. This paper presents preliminary results from an empirical study investigating these challenges through a qualitative approach using semi-structured interviews. The survey is exploratory with the objective of eliciting relevant topics for further research. Seven employees at five software companies w
In order to reduce the vibration transmission in multi-storey wood buildings, it is common to insert viscoelastic elastomer materials between parts of the buildings. The studies presented here investigate to which extent different design choices for the elastomer layers affect the isolation of low-frequency vibrations (0-100 Hz). A finite element model of two storeys of a multi-storey wood buildin
The purpose of this book chapter is to investigate to what extent technical function can be protected under European Union (EU) copyright law. Technical function has been explicitly excluded under other regimes of protection in the Union, for example, trademark and design protection law, to avoid overlap (also known as cumulation) between these regimes and patent law. No such statutory provisions
This chapter illustrates how quantum chemical calculations can be used to elucidate structural and functional aspects of tetrapyrrole cofactors, focusing on porphyrins, cobalamins, coenzyme F430, and chlorophyll. A particular emphasis is put on the biochemical significance of axial ligands, which can tune the function of the tetrapyrroles. With the use of quantum chemical calculations, it is possi
This paper describes the research stimulated by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defence purposes, away from the selling of products to the provision of services. This research was undertaken in an aerospace company, which designs and manufactures aero engines and also offers contracts, under which it remains responsible for
Abstract in Danish Observationsmetoder og billeddannelsesteknikker ? vurderinger af den fysiske eksponering i repetitivt arbejde med focus på nakke, skuldre og arme Formålet var at udvikle, etablere og validere observationsmetoder til eksponeringsvurderinger i epidemiologiske undersøgelser af repetitivt arbejde. Et andet formål var at øge kvaliteten af input data til brug i biomekaniske skuldermoObservation methods and imaging techniques - assessments of physical exposure in repetitive work with focus on neck and upper extremities The aim of this thesis was to develop, establish and validate observation methods for exposure assessments in epidemiological studies of repetitive work. A second aim was to increase the quality of input data for biomechanical shoulder models, by reliability an
I skönlitterär prosa förekommer det strängt taget enbart tre olika temporala texttyper: narration (berättande text, relation), citat (alltså dialog) och berättarens nutid (dvs. passager där en berättare talar i egen sak), och det finns bara två finita tempus att välja emellan: presens och preteritum. Det kan tyckas som om de skönlitterära författarna har ett snävt spelrum att operera inom. Men det
