The perennial herbaceous crop Arundo donax is a potential feedstock for second-generation bioethanol production. In the present work, two different process options were investigated for the conversion of two differently steam-pretreated batches of A. donax. The pretreated raw material was converted to ethanol with a xylose-consuming Saccharomyces cerevisiae strain, VTT C-10880, by applying either
The formation of amyloid fibrils by the intrinsically disordered protein alpha-synuclein is a hallmark of Parkinson disease. To characterize the microscopic steps in the mechanism of aggregation of this protein we have used in vitro aggregation assays in the presence of preformed seed fibrils to determine the molecular rate constant of fibril elongation under a range of different conditions. We sh
The combustion and melt dripping of poly(ethylene-co-butyl acrylate) (EBA), EBA blended with polypropylene (EBAePP) and poly (ethylene-co-methacrylic acid) (EMAA), each blended with calcium carbonate and polydimethylsiloxane, were studied. In situ measurement of the temperature gradient in the cone calorimeter were combined with infrared spectroscopy measurements on specimens withdrawn and quenche
We use a nested-grid version of the GEOS-Chem chemistry transport model, constrained by isoprene emissions from the Model of Emissions of Gases and Aerosols from Nature (MEGAN), and the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS) bottom-up inventories, to evaluate the impact that surface isoprene emissions have on formaldehyde (HCHO) air-mass factors (AMFs) and vertical column densit
Popular Abstract in Swedish Under de senaste decennierna har matematisk modellering av finansiella marknader rönt stor uppmärksamhet både inom akademi och inom industri. Ett område som har visats särskilt intresse är prissättning av finansiella instrument så som optioner. En europeisk köpoption på en underliggande aktie är ett kontrakt som ger innehavaren rätten att vid en förutbestämt tidpunkt, The first part of this thesis deals with approximations of stochastic integrals and discrete time hedging of derivative contracts; two closely related subjects. Paper A considers the problem of approximating the value of a Wiener process. The discretization points are placed at times when the absolute difference between the value of the process and the approximation reaches a threshold level. It i
Power supply systems play a very important role in everyday life applications. There are mainly two ways of producing energy for low power generation: electrochemical batteries and small engines. In the last few years, many improvements have been carried out in order to obtain lighter batteries with longer durations but unfortunately the energy density of 1 MJ/kg seems to be an asymptotic value. A
This thesis is an empirical study of how positioning is achieved in interactional Swedish. Positioning has previously been described in terms of epistemic modality, interpersonal positioning, stanceand speech act adverbials. The aims of the study are, firstly, to identify what linguistic resources are used to achieve positioning in interaction. A second aim is to describe where in the turn-con
We were interested in catalogers as human beings and in their reaction to a changed working situation. In the light of the changes which have been made at the libraries during the nineties, we investigated why the very group catalogers reacted with an intense and engaged open debate at the same time as librarians with special competence didn t seem to react in this way. The open debate about the c
Sydvästra Grönlands arkeiska berggrund (North Atlantic Craton, NAC) intruderades av ett stort antal mafiska intrusioner och diabasgångar under arkeikum och proterozoikum, vars åldrar är dåligt kända. Detta arbete omfattar dateringar av fem intrusioner med U-Pb metoden av mineralen zirkon och baddeleyit från tre olika generationer av mafiska bergarter. En mafisk-ultramafisk lagrad intrusion i FiskeThe Archaean bedrock of southern Greenland (the North Atlantic Craton) is host to a large number of mafic intrusions and dyke swarms. This study present a robust U-Pb zircon age of 2990.1 ± 13 Ma for a mafic-ultramafic layered intrusion in the Fiskefjord region and four baddeleyite U-Pb ages of doleritic dykes that range between c. 2500 and c. 2050-2030 Ma. The dyke located SE of Ameralik Fjord is
After identifying an association between maternal Epstein-Barr virus (EBV) reactivation and acute lymphoblastic leukemia (ALL), the authors analyzed a nested case-control study within Finnish and Icelandic maternity cohorts with 7 million years of follow-up to confirm EBV's role in ALL. Offspring of 550,000 mothers were followed up to age 15 years during 1975-1997 by national cancer registries to
There are many different factors that influence our perception of products i.e. personal, product related and external factors. For designers to be able to address them all when creating new products, we need to deepen our understanding of the totality of perceptual experiences from non-instrumental interaction with products. One way of achieving this is by stimulating the creative process by util
Background: There is an evident need for improved management of elderly patients with trauma in order to avoid common and troublesome complications such as delirium. The aim of this study was to investigate whether an implementation of a multi-factorial program including intensified pre-hospital and perioperative treatment and care could reduce the incidence of delirium in elderly patients with hi
Manual gestures and speech form a single integrated system during nativelanguage comprehension. However, it remains unclear whether this hold forsecond language (L2) comprehension, more specifically for simultaneousinterpreting (SI), which involves comprehension in one language and simultaneousproduction in another. In a combined mismatch and priming paradigm,we presented Swedish speakers fluent i
There has been much progress in the field of nanofluidics, and novel applications, such as single-cell analysis, have been achieved. In such cases, controlling the location of the gas/liquid interface is vital and partial hydrophobic modification is frequently used to pin the position of this interface. However, because the fluid manipulating pressure in such devices is comparable to the Laplace p
BACKGROUND: Quality of surgical care as a crucial component of a comprehensive multi-disciplinary management improves outcomes in patients with endometrial carcinoma, notably helping to avoid suboptimal surgical treatment. Quality indicators (QIs) enable healthcare professionals to measure their clinical management with regard to ideal standards of care. OBJECTIVE: In order to complete its set of
We study Hinode/EIS observations of an active region taken before, during, and after a small C2.0 flare in order to monitor the evolution of the magnetic field and its relation to the flare event. We find that while the flare left the active region itself unaltered, the event included a large magnetic field enhancement (MFE), which consisted of a large magnetic field strength increase to values ju
Sustainable groundwater resources management in arid areas requires early and immediate action to prevent further negative impacts on these resources. The persistent decline in the quantity and quality of groundwater in many countries has been leading to severe challenges in the present and future. In this research, the factors affecting groundwater salinization in a coastal aquifer were evaluated
Introduction: When a child is diagnosed with Type 1 diabetes, it involves extensive lifestyle changes for the whole family. There is limited knowledge of the impact the initial care has for children and parents over time. The aim was to compare children’s diabetes-specific health-related quality of life (HRQOL) in hospital-based care and hospital-based home care (HBHC), 12 and 24 months after the
