Amperometric carbon paste peroxide sensors based on horseradish peroxidase (HRP) were developed. In the first approach, HRP was chemically modified with polyethylene glycol to improve the stability of the enzyme in the organic paste matrix and compared with native HRP electrode. In the second approach, HRP was "wired" with a redox polymer containing a covalently bound phenoxazine type mediator, to

Popular Abstract in Swedish Arbetet i denna avhandling syftar till att förbättra etanolproduktionen från lignocellulosa. Etanol framställd från förnyelsebara råvaror har fått förnyad uppmärksamhet på grund av den växande medvetenheten om den globala uppvärmningen och farhågor för en trytande tillgång på olja. Lignocellulosa utgör en potentiell råmaterialkälla för framtida storskalig etanolproduktiThe work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. To produce ethanol from lignocellulose, the hemicellulose and cellulose

Alkali metal adsorption on metals is studied by High Resolution Core Level Spectroscopy (HRCLS) and Low Energy Electron Diffraction (LEED). The studies can be divided into two parts: adsorption of alkali multilayers and alkali adsorption in the submonolayer regime. In the case of the adsorption of alkali multilayers, the interface region between a thin alkali film of Na,K,Rb and Cs on different s

In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. Nevertheless, high production costs associated with traditional PHA production based on fermentation by pure microbial cultures have so f

De nordliga höga latitudernas fysiska miljö, inklusive kryosfären i Arktis, har genomgått dramatiska förändringar under de senaste decennierna tack vare uppvärmning och andra klimatförändringar kopplade till antropogena utsläpp av växthusgaser. Uppvärmningen i regionen är ungefär det dubbla jämfört med ökningen i medeltemperaturen globalt. Globala klimatmodeller förutspår att denna förstärkta uppvThe physical environment in the northern high latitudes including the Arctic cryosphere has undergone dramatic changes due to anthropogenic greenhouse gas warming, which since pre-industrial times has been twice or more the rate of global mean warming. Global climate models predict that this accelerated warming will continue for at least the next few decades. Meanwhile, the arctic and subarctic ve

Popular Abstract in Swedish Alla friska människor har 46 kromosomer, 23 av dessa härstammar från modern och 23 från fadern. Kromosomer är långa kedjor av nukleinsyror som innehåller den genetiska informationen (arvsanlagen) som behövs för att ett befruktat ägg skall kunna utvecklas till en individ bestående av miljontals celler med mycket specialiserade och avancerade uppgifter. Den här utvecklingThe cells in B cell development can be divided into several subgroups or fractions, e.g. early-pro-B-, pro-B, large-pre-B-, small-pre-B-, immature and mature B cells, where the stages reflect the maturity degree of the cells. This characterization is based on the expression of intracellular markers such as the recombination activating genes 1 and 2(Rag 1 and Rag 2), the terminal deoxynucleotidyl t

Popular Abstract in Swedish Avhandlingen tar upp polariserade plats-koncept (place/non-place, place/placelessnes, place/site etc. En modaliserande approach prövas, dvs nyanser och aspekter framhålls som alternativ till polariteter och dikotomier. Del 1 innefattar platsteori genom Edward Casey, Edward Relph, Kenneth Frampton, Perla Korosek-Serfaty och Henri Lefebvre. Här görs en kritisk läsning av In this thesis the notion of place is studied by way of investigating the “non-place” which is excluded or opposed, whenever a place is defined. “Non-place” is used here as a meta-concept, covering various recurring types of opposition to “place,” and it therefore represents a profoundly incoherent spect-rum of realities and concepts. Hence, a “non-place” may in this investigation appear as “lefto

This report describes a model for the estimation of the time required to evacuate a building, by dividing the evacuation process into three phases: awareness, behaviour and response, and movement. The times required in each of these phases can be estimated separately and the sum then represents the total evacuation time. The time elapsed from the fire breaking out, to the discovery of the fire, is

The thesis should be regarded as a contribution to the development of knowledge about the interaction taking place in the educational setting for pupils with PIMD in Sweden, the training school (Sw. Träningsskola), and the contextual and interactional conditions that characterizes this educational setting. The study is expected to contribute to a deeper understanding of the pedagogical praxis in t

We present a formulation of the scattering matrix method for spin-dependent electron transport in a quantum waveguide with spin-orbit interaction (SOI). All the required Hamiltonian matrices needed in the implementation of the formulation are represented in a basis of the transverse spatial eigenstates and the spin eigenstates of the leads. Thus the method has great flexibility and can be easily a

Drought is predicted to increase in the future due to climate change, bringing with it myriad impacts on ecosystems. Plants respond to drier soils by reducing stomatal conductance in order to conserve water and avoid hydraulic damage. Despite the importance of plant drought responses for the global carbon cycle and local and regional climate feedbacks, land surface models are unable to capture obs

Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.

Background: In image processing for activity quantification, the end goal is to produce a metric that is independent of the measurement geometry. Photon attenuation needs to be accounted for and can be accomplished utilizing spectral information, avoiding the need of additional image acquisitions. The aim of this work is to investigate the feasibility of 177Lu activity quantification with a small

This talk reports on the compilation of the new London–Lund Corpus (LLC–2) –a corpus of contemporary spoken British English, collected 2014–2019. The sizeand design of LLC–2 are the same as that of the world’s first corpus of spokenlanguage, namely the London–Lund Corpus (LLC–1), with spoken data mainlyfrom the 1960s. In addition to the fact that we have a corpus of contemporary speech, the existe

Background and objective: Clinical practice guidelines for prostate cancer (PCa) are a valuable resource for everyday clinical practice. The clinical practice guidelines and recommendations produced by various societies should demonstrate a considerable level of consistency in terms of quality, regardless of the society that developed these given the common evidence base. However, to date, no stud

Context. Open clusters are ideal tools for tracing the abundances of different elements because their stars are expected to have the same age, distance, and metallicity. Therefore, they serve as powerful tracers for investigating the cosmic origins of elements. This paper expands on a recent study by us, in which the element fluorine was studied in seven open clusters; here we add six open cluster

BackgroundHome care is beset with work environment issues and high staff turnover, while research concerned with interventions to improve the work environment is sparse. Few of the existing interventions apply a participative approach, despite this being associated with more positive outcomes and sustainable change. This paper presents a framework, rooted in action research and action learning, fo
