The UV-dissipative mechanisms of the eumelanin building block 5,6-dihydroxyindole-2-carboxylic acid (DHICA) and the 4,7-dideutero derivative (DHICA-d(2)) in buffered H(2)O or D(2)O have been characterized by using ultrafast time-resolved fluorescence spectroscopy. Excitation of the carboxylate anion form, the dominating state at neutral pH, leads to dual fluorescence. The band peaking at lambda=37
Alloreactive memory T cells are major barriers to transplantation acceptance due to their capacity to accelerate rejection. Here, we investigated the effects of combined treatment with arsenic trioxide (As(2)O(3)) and blocking monoclonal antibodies (mAb) against CD154 and LFA-1 (anti-CD154/LFA-1) on graft survival as well as changes in pathology and immunological responses in mice with adoptively
The thorough experimental characterization of a dowel-type connection under various combinations of bending moments and normal forces is presented in this study. Double-shear steel-to-timber connections with 12 and 20 mm steel dowels were tested in a 4-point bending test set-up. The load, between the connected steel and wood beams, was transferred by the dowels themselves and also via an additiona
An analysis of inelastic photoproduction of J/psi mesons is presented using data collected at the ep collider HERA corresponding to an integrated luminosity of above 80 pb(-1), Differential and double I < P-t/psi(2) < differential cross sections are measured in a wide kinematic region: 60 < W-gammap < 260 GeV, 1 p(t,psi)(2) < 60 GeV2 and 0.05 < z < 0.9. where z is the fraction of the energy of the
The electroenzymatic reactions of Trametes hirsuta laccase in the pure organic solvent dimethyl sulfoxide (DMSO) have been investigated within the framework for potential use as a catalytic reaction scheme for oxygen reduction. The bioelectrochemical characteristics of laccase were investigated in two different ways: (i) by studying the electroreduction of oxygen in anhydrous DMSO via a direct ele
The present study introduces sparse modeling for the estimation of propagation patterns in intracardiac atrial fibrillation (AF) signals. The estimation is based on the partial directed coherence (PDC) function, derived from fitting a multivariate autoregressive model to the observed signals. A sparse optimization method is proposed for estimation of the model parameters, namely, the adaptive grou
The objective of this study was to assess the influence of user behaviour on the Smart Grid performance and to identify possible interfaces between end-users and the energy network. In order to get an image of the electricity customers attitude to Smart Grids and energy-efficiency, a questionnaire was conducted as a first step. Afterwards, a combination of thermal building simulations and the deri
In this report, the dynamics of an aertor of an activated sludge process is studied. Two control strategies for the dissolved oxygen concentration are tested. One contains either a PI-controller or an on-off controller, the other a self-tuning controller.
There are two key-parameters in the system, KLa, the total oxygen transfer rate, and OUR, the oxygen uptake rate of the microorganisms
Dynamic capabilities enable firms to systematically modify their resource base and build competitive advantage. As dynamic capabilities literature is diverging in definition and scope, this research work analyzes conceptual literature on dynamic capabilities regarding commonalities, differences, and development over time. Therefore, a total of 56 publications in eleven highly ranked journals betwe
Handelsbolag och kommanditbolag är juridiska personer men inte skattesubjekt vid inkomstbeskattning. Huvudregeln är att ett sådant bolags resultat beskattas hos dem som är delägare i bolaget vid räkenskapsårets utgång. Den skattemässiga fördelningen ska i princip grundas på bolagsavtalet eller vad som annars har avtalats mellan delägarna. Syftet med förevarande uppsats är att utreda huruvida friTrading partnerships and limited partnerships are legal entities but not a taxable subject for income taxation. The main rule is that the profit of such a company is taxed on those who are partners in the company at the end of the financial year. The tax distribution shall in principle be based on the company agreement or what has otherwise been agreed upon between the partners. The purpose of th
The work of Beppe Fenoglio, a well-known Italian writer, has increased in popularity in the 90s, more than 30 years after his death. As a reaction to the change in the Italian political scene with the entry of the neo fascist party in the government in the 90s, the new generation felt a need to defend the democratic ideals; this might explain the rediscovery the works of Fenoglio where the partisa
An investigation of how electron/photon beam exposures affect the intercalation rate of Na deposited on graphene prepared on Si-face SiC is presented. Focused radiation from a storage ring is used for soft X-ray exposures while the electron beam in a low energy electron microscope is utilized for electron exposures. The microscopy and core level spectroscopy data presented clearly show that the ef
An automated routine for the continuous calibration of thermographic phosphors was developed as a replacement for the conventional calibration scheme that relied on fixed temperature points. The automated calibration routine was validated using Mg 3 F 2 GeO 4 :Mn as a calibration phosphor. Hardware and software aspects of the calibration process were addressed in this development. The hardware asp
This thesis investigates the media discourse of the Swedish party Feminist Initiative in conjunction with the election to the European Parliament, and the general national election, in May and September 2014. Through the methods of narrative analysis and critical discourse analysis, it identifies the dominating media approaches and attitudes towards the party, and analyses what norms and structure
With the shift toward de-escalating surgery in breast cancer, prediction models incorporating imaging can reassess the need for surgical axillary staging. This study employed advancements in deep learning to comprehensively evaluate routine mammograms for preoperative lymph node metastasis prediction. Mammograms and clinicopathological data from 1265 cN0 T1-T2 breast cancer patients (primary surge
We here develop stable bidimensional magnetic nanoclusters (2D-MNCs) of iron oxide nanocubes (IONCs) arranged in thin nanosheets of closed-packed nanocubes. The assembly occurs by means of a two-step approach: in the first one, the ionic surfactant, sodium dodecyl sulfate (SDS), acts as a transient water transfer agent and as 2D clustering agent to induce formation of a monolayer of nanocubes arra
