O 1s x-ray absorption spectroscopy (XAS) in conjunction with photoelectron spectroscopy has been used to explore the conduction-band edge of single crystalline and nanostructured anatase TiO2. The experiments are supported by ab initio density-functional calculations in which both the initial and core hole final states are considered. The calculations show that the states at the conduction-band ed

Abstract in UndeterminedThe present study investigated the relation between reaction to negative stimuli and memory for stimuli. The relation was further investigated using as a framework individuals’ affective temperaments (AFTs). Eighty adolescents participated in the study. The AFTs are based on selfreported affect and categorizes individuals in four temperaments: self-actualizing, high affecti

Nanocomposite membranes based on poly-(ethylene-co-vinyl acetate) copolymer (18% vinyl acetate content)and two different organomodified clays have been prepared by mechanical mixing using two roll mill method. The morphology of the nanocomposites was investigated using small angle X-ray scattering, scanning electron microscopy, and transmission electron microscopy. The mechanical and thermal studi

Multiple genetic loci confer susceptibility to breast and ovarian cancers. We have previously developed a model (BOADICEA) under which susceptibility to breast cancer is explained by mutations in BRCA1 and BRCA2, as well as by the joint multiplicative effects of many genes ( polygenic component). We have now updated BOADICEA using additional family data from two UK population-based studies of brea

Previous case-control studies have suggested that a high intake of animal foods and its associated nutrients are associated with an increased risk of renal cell carcinoma, although data from prospective studies are limited. We report here on the relationship between macronutrient intake and renal cell carcinoma incidence among 435,293 participants enrolled in the European Prospective Investigation

Meso-tetrakis (4-bromo-2-thiophene) and (5-bromo-2-thiophene) porphyrins were synthesized in 18% yield from freshly distilled pyrrole and the corresponding aldehydes in refluxing propionic acid. Reaction of both porphyrins with either Zn(OAc)(2)center dot 2H(2)O Or Ag(OAc) afforded the corresponding metal complexes in 20% yield. The free bases and metal complexes were characterized by IR, NMR, EPR

Objectives: To assess the prevalence of pharyngeal and oesophageal symptoms and dysmotility in patients with primary Sjogren's syndrome ( pSS) and relate these to autonomic nervous function. Methods: Twenty consecutive pSS patients, according to the American - European Consensus Criteria ( AECC), and 30 age- and sex- matched controls from the Swedish general population registry were studied. All s

River-dominated coastal areas are typically sites of active biogeochemical cycling, with productivity enhanced by terrestrial inputs of nutrients and organic matter. To examine the spatial variability and relationship between river discharge, phytoplankton, and organic carbon distributions, we analyzed surface water and sediment from the Louisiana shelf adjacent to the Mississippi River. Samples w

Rosiglitazone, peroxisome proliferator-activated receptor-gamma agonist, is an insulin sensitizing agent in peripheral tissues. This study investigated islet hormones and hormone-like peptides expression patterns in rosiglitazone treated streptozotocin (STZ)-diabetic rats by using immunohistochemistry and in situ hybridization methods. Animals were divided into four groups. I. Group: Intact contro

Three new species, i.e. Hieracium evae I Tyler, Hieracium jonsbergense T. Tyler, Hieracium subnitidum Dahlst. ex T. Tyler, and one variety, i.e. H. ravidum Brenn. var. exaltifrons T. Tyler var. nov. are described. Hieracium myrtillinum (Johanss. ex Dahlst.) T. Tyler comb. nova is proposed. All are based on material collected in the SE Swedish provinces Gotland and Ostergotland.

The influence of the latex surface chemistry on the association of latices with different cellulose derivatives has been investigated by means of isothermal calorimetry and electrophoresis. The chemistries of three grades of coating latices differed with regard to the type and amount of vinylic monomer and the level of carboxylation. In addition, a styrene/butadiene latex substantially free from s

Instrumentation, control and automation (ICA) are key technologies in modern water and wastewater systems. Ever present disturbances make it necessary to automatically attenuate their consequences. A wastewater treatment system is load driven, while a water distribution system is demand driven. Despite the variability the system outputs have to be satisfactory. Economic realities encourages the ap

The method of normal form originating from the work of A.D. Brjuno has been used in the analysis of two-degrees-of-freedom discrete systems with eccentric follower force. Various types of external and internal damping has been taken into consideration. The program NORFOR2 is compared with program BIFOR2, which is based on Hopf Bifurcation, as to the capacity and speed in solving non-linear, non-co

Nectar-feeding animals can use vision and olfaction to find rewarding flowers and different species may give different weight, to the two sensory modalities. We have studied how a diurnal or nocturnal lifestyle affects the weight given to vision and olfaction. We tested naive hawkmoths of two species in a wind tunnel, presenting an odour source and a visual stimulus. Although the two species belon

Using the Fourier Transform Spectrometer at Lund Observatory, intensity calibrated spectra of singly ionized zirconium have been recorded and analyzed. Oscillator strengths for 263 Zr II spectral lines in the region 2500-5400 angstrom have been derived by combining new experimental branching fractions with previously measured radiative lifetimes. The transitions combine 34 odd parity levels with 2

To find out how the ‘generic person’ is expressed in English and Swedish, the use and correspondence of the generic pronouns one in English and man in Swedish are examined in a bidirectional English-Swedish translation corpus. The material demonstrates clearly the greater frequency and versatility of Swedish man and the restricted use of English one. The difference is partly register-related: whil
