Electron transfer (ET) of ligninolytic peroxidases was studied in the bioelectrocatalytic reduction reaction of H2O2 at peroxidase-modified graphite electrodes. Specifically, native lignin (LiP) and manganese (MnP) peroxidases secreted by Phanerochaete chrysosporium, as well as a few different recombinant MnP forms were used in the electrochemical studies. The recombinant enzymes included wild-typ

The rotational capacity of a plastic hinge is analysed by means of a new approach, where the strain localization in the compression zone is taken into account. This leads to a strong size dependency of the rotational capacity. Comparisons with test results confirm this conclusion.

In this work, a three-dimensional computational method has been further developed for a composite duct, to analyze water phase change and liquid water saturation level, two-phase flow and heat transfer in a multi-component mixture. The duct under consideration consists of a flow duct, porous layer and solid structure. Advanced boundary conditions are applied in the analysis, concerning the thermal

Popular Abstract in Swedish Sjukdomar som drabbar hjärtats kranskärl och ger upphov till bland annat hjärtinfarkt är den vanligaste dödsorsaken både i Sverige och i resten av världen. Avsikten med denna avhandling är att ge en bild av livskvaliteten hos hjärtpatienter samt att ta upp problem inom medicinsk etik, som berör dessa patienter. Män och kvinnor som vårdats för hjärtinfarkt vid UniversiteOne month and one year after acute myocardial infarction (AMI) (n=296), coronary artery bypass grafting (CABG) (n=99) and percutaneous coronary intervention (PCI) (n=18) patients completed a questionnaire for self-assessment of quality of life (QoL) during the period 1989?1991. Patients differed from age- and sex-matched controls (n=88) in both somatic and emotional dimensions, but less after one

This paper describes a predictive PI controller with dead-time compensation. The advantage of the new controller compared with other dead time compensating controllers is that it contains only three adjustable parameters; the gain, the integral time and the dead time. The controller is also suited for processes with varying dead times.

De högsta studiekraven kommer från studenterna själva. Så beskriver majoriteten av studenterna i denna studiemiljöundersökning studierna vid Lunds universitet. I andra hand betonas kraven från arbetsmarknaden och först i tredje hand utbildningens krav sådana de förmedlas i undervisningen av lärare och handledare. Undersökningen ger bilden av den existentiellt sett ensamma studenten med höga krav p

Elements emitted to the atmosphere are partly exported to more remote areas and contribute to the regional and territorial deposition rates. This study is based on the principle that carpet-forming bryophytes (pleurocarpic mosses) absorb elements and particles from rain, melting snow and dry deposition. We compare the concentrations of 60 elements in carpets of the forest moss Pleurozium schreberi

Four experimental methods were used to study the phase diagram, as well as the thermodynamic and structural properties of the binary system n-octyl alpha-D-glucoside water in the temperature range 25-130degreesC. Sorption calorimetry allows one to determine the activity of water and enthalpy of mixing as functions of water content at constant temperature, while DSC scans temperature at constant co

Discussion of aesthetics within a pedagogical context

The work presented deals with the characterisation and application of critical gels. In order to provide a theoretical foundation, the thermodynamics of the reversible swelling and shrinking behaviour of such gels is outlined. The temperature-sensitive poly(N-isopropylacrylamide) gel (NiPAAm) was chosen for experimental investigation. Dif ferent methods of producing the gel are described, and the

The main concern of the paper is to address some problems that arise when defining the concept of contrast and to clarify the relation between contrast and other concepts of information structure. As to the definition of the notion of contrast, we need to separate the semantic and pragmatic aspects of contrastiveness as well as identify different types within these two main categories. There is ab

The singlet ground and low-energy excited states of the benzene dimer in D-6h geometry are characterized using second order multireference perturbation theory (CASPT2). The counterpoise-corrected spectroscopic parameters of the benzene excimer are in quantitative agreement with experiment. The same method was used to compute a submanifold of the potential energy hypersurface of the first excited s

Estimates of viability as measured by vital staining with fluorescein diacetate (FDA) were carried out on freshly isolated and partially aged (16-h-old) B. vulgaris and H. vulgare mesophyll protoplasts following irradiation with UV-B. Damage to the photosynthetic system by UV-B was determined by delayed light emission (DLE). In the case of freshly isolated protoplasts Beta was .apprx. 30% more sus

It is shown that in water of finite depth, the surface profile eta of a periodic traveling wave uniquely determines the corresponding flow in the body of the fluid. This holds for rotational flow as long as the vorticity function gamma(psi) satisfies the condition gamma'(psi) max(xis an element ofR) eta(2)(x) < pi(2). This condition is also shown to be sharp.
