Ab initio calculations of low-lying electronic states of CrH are presented, including potential energies, dipole and transition dipole moment (TDM) functions, and radiative lifetimes for X (6)Sigma(+), A (6)Sigma(+), 3 (6)Sigma(+), 1 (6)Pi, 2 (6)Pi, 3 (6)Pi, and (6)Delta. Calculation of dynamic correlation effects was performed using the multistate complete active space second-order perturbation m

Various transport phenomena occurring in an anode duct of medium temperature solid oxide fuel cell (SOFC) have been simulated and analyzed by a fully three-dimensional calculation method. The considered composite duct consists of a thick porous layer, the gas flow duct and solid current interconnector. Unique fuel cell boundary and interfacial conditions, such as the combined thermal boundary cond

This paper reports on research to estimate leaf area index (LAI) in Swedish forests with satellite sensor data. The study is part of a research programme that aims at generating input data for process-oriented forest carbon models. Field-work was carried out in two areas in Sweden about 530 km apart, in the nemoral and boreo-nemoral forest regions. Various ways of estimating LAI in the field were

Objective: To compare the colloids 5% albumin, 4% gelatin, and 6% HES 130/0.4 with one another and with normal saline regarding their plasma expanding effects at increased permeability and to compare the results with those from a previous study at normal permeability. Design and setting: Prospective controlled randomized laboratory study in a university research laboratory. Subjects: 48 adult male

Health risks associated with exposure to airborne particulate matter (PM) have been shown epidemiologically as well as experimentally, pointing to both respiratory and cardiovascular effects. Lately, wear particles generated from traffic have been recognized to be a major contributing source to the overall particle load, especially in the Nordic countries were studded tires are used. In this work,

Background: The ECL cells are histamine-producing endocrine cells in the oxymic mucosa that synthesize and secrete proteins and peptides. They are the primary target for gastrin and mediate the control of gastrin on acid secretion and oxyntic mucosal growth. Knowledge of the molecular biology of the ECL cell is therefore important for understanding gastric physiology. Accordingly, we wanted to ide

With the aim to improve our understanding of the structural basis for protein self-association and aggregation, in particular in relationship to protein refolding and amyloid formation, folding-related processes for human cystatin C have been studied. Using NMR spectroscopy together with chromatographic and electrophoretic methods, a self-association process resulting in dimer formation for protei

We study the problem of estimating the position and orientation of a calibrated camera from an image of a known scene. A common problem in camera pose estimation is the existence of false correspondences between image features and modeled 3D points. Existing techniques Such as RANSAC to handle outliers have no guarantee of optimality. In contrast, we work with a natural extension of the L-infinity

Popular Abstract in Swedish Syftet med den här avhandlingen är att studera några av de problem som är förknippade med implementering av så kallad autentisk bedömning i lärarutbildningen. I den första delen av avhandlingen undersöks, genom en litteraturöversikt, huruvida användningen av bedömningsmatriser kan fungera som ett stöd för ökad tillförlitlighet och trovärdighet vid bedömning av komplexa The aim of this dissertation is to explore some of the problems associated with introducing authentic assessment in teacher education. In the first part of the dissertation the question is investigated, through a literature review, whether the use of scoring rubrics can aid in supporting credible assessment of complex performance, and at the same time support student learning of such complex perfo

Production of glycidyl ethers is industrially carried Out by reacting alcohols with epichlorhydrin, a potentially carcinogenic compound. This paper investigates a less hazardous alternative-that of a chemo-enzymatic process in which Candida antarctica lipase B catalysed generation of peracid from a carboxylic acid is followed by a Prileshajev epoxidation of the corresponding allyl ether. Trimethyl

This paper aims to make a systematic study of human dura to establish the presence of fluid transport channels and their relationship to age. Samples of parasagittal dura from autopsy cases from mid-gestation to the ninth decade were examined by light microscopy. We have demonstrated the presence of unlined rounded spaces, uncommon in the fetus and neonate but increasingly evident after 30 weeks o

Acylglutamate is a divalent anionic surfactant whose properties are affected by its degree of neutralization. In this study, we present phase maps for aqueous systems of the potassium (LGP) and triethanolamine salts (LGT) of N-lauroyl L-glutamic acid, at different degrees of neutralization. A cubic phase forming between the isotropic micellar and the hexagonal phase was detected in both LGP/water

Titania-supported copper oxide catalysts have been prepared with loadings in the range from 1/3 to 5 theoretical layers and have been tested for the combustion of CO and toluene. Characterisation with XRD, electron microscopy, EDX, TPR, Raman, and XPS gives details about the structure of copper oxide on titania. The results show that dispersed CuOx is formed up to a loading of about one theoretica

Treatment with alkali, particularly overliming, has been widely used as a method for the detoxification of lignocellulose hydrolysates prior to ethanolic fermentation. However, the mechanisms behind the detoxification effect and the influence of the choice of cation have not been well understood. In this study, a dilute acid hydrolysate of spruce and an inhibitor cocktail consisting of six known i

The gathering pace of IT innovation has, or ought to have had notable methodological repercussions for the social-science community (and beyond). Where yesterday the researcher could unhurriedly unlock the social-scientific significance of a chosen medium, secure in the knowledge that his or her work would have bearing for many years, by now there is every reason to confront a fear that the prodde

Objective: Investigate effects of estrogen at gene expression and functional levels in vascular wall cells treated with bacterial lipopolysaccharide (LPS). Materials and methods: Aortic segments from ovariectomized mice were treated with LPS for 24 h in the absence or presence of 17 beta-estradiol (E-2). Gene activity was determined by Affymetrix microarray analysis and real-time RTPCR. Adhesion o

3-Hydroxy fatty acids (3-OH FAs) of 10-18-carbon chain lengths are constituents of the lipopolysaccharide of Gram-negative bacteria. These acids are used as chemical markers for determining endotoxin in environmental samples. The present communication addresses the question whether this type of analysis also would be applicable to mammalian samples. Low levels (6.1 +/- 1.6-94.0 +/- 23.2 pmol/ml) o
