Ultrasound Doppler for improved diagnosis of disease in the paranasal sinuses

We propose a method to improve the diagnosis of infection in the paranasal sinuses, distinguishing between mucous and serous cases. The method utilizes a previously published method whereby the viscosity in a sealed container may be measured using an ultrasound Doppler method. As ultrasound propagates in a liquid medium, due to attenuation, the resulting pressure gradient will cause the liquid to

Intrageneric phylogeny of Capsella (Brassicaceae) and the origin of the tetraploid C-bursa-pastoris based on chloroplast and nuclear DNA sequences

Polyploidization, often accompanied by hybridization, has been of major importance in flowering plant evolution. Here we investigate the importance of these processes for the evolution of the tetraploid crucifer Capsella bursa-pastoris using DNA sequences from two chloroplast loci as well as from three nuclear low-copy genes. The near-absence of variation at the C. bursa-pastoris chloroplast marke

Probing the liquid-gas coexistence in p+Xe reactions from 200 to 1400 MeV

The nuclear equation of state (EOS) is probed from statistical parameters, determined in an excitation function experiment on p + Xe-nat reactions at 200-1400 MeV. Total charge (Z) distributions follow a cascade-[multi]fragmentation-evaporation (CFEM) model well. The caloric curve in regions supposedly dominated by fast processes is compatible with a pure statistical multifragmentation (SMM) proce

Scattering-assisted electric current in semiconductor superlattices in the Wannier-Stark regime

We have used the Monte Carlo technique to investigate the mechanism of scattering-assisted charge transport in semiconductor superlattices under a strong applied electric field in the Wannier-Stark (WS) regime. The distribution function of quasi-two-dimensional carriers localized in each WS level is calculated, and the contributions of different scattering mechanisms to the total scattering probab

Oxidation and reduction of pyridine nucleotides in alamethicin-permeabilized plant mitochondria

The inner mitochondrial membrane is selectively permeable, which limits the transport of solutes and metabolites across the membrane. This constitutes a problem when intramitochondrial enzymes are studied. The channel-forming antibiotic AlaM (alamethicin) was used as a potentially less invasive method to permearbilize mitochondria and study the highly branched electron-transport chain in potato tu

Multidisciplinär rehabilitering till vad nytta?

Det finns nu vissa bevis för att multidisciplinära insatser har effekt vid långvariga muskuloskeletala besvär. I denna studie förbättrades också patienternas livskvalitet mer i rehabiliteringsgruppen jämfört med en kontrollgrupp från primärvården. Hög motivation hos patienten ger bättre resultat.

Fast inversion of the Radon transform using log-polar coordinates and partial back-projections

In this paper a novel filtered back-projection algorithm for inversion of a discretized Radon transform is presented. It makes use of invariance properties possessed by both the Radon transform and its dual. By switching to log-polar coordinates, both operators can be expressed in a displacement invariant manner. Explicit expressions for the corresponding transfer functions are calculated. Further

Autosomal dominant retinitis pigmentosa with a rhodopsin mutation (Arg-135–Trp): Disease phenotype in a Swedish family

We here present the clinical phenotype in 6 patients from a family with autosomal dominant retinitis pigmentosa found to carry a point mutation in the rhodopsin gene (arginine-135-tryptophan). The mutation is the second found by mutation screening of DNA from 20 Swedish families with dominant retinitis pigmentosa. With full-field electroretinography we could document a severe form of retinitis pig

New evidence for an association between the CSF HVA:5-HIAA ratio and psychopathic traits

OBJECTIVES: To replicate the relation between the CSF HVA:5-HIAA ratio and psychopathic traits previously reported in a pilot group of 22 perpetrators of violent crimes. METHODS: CSF monoamine metabolite concentrations in another 28 violent and sexual offenders, aged 45 or below, referred to pretrial forensic psychiatric investigation, were compared to features of psychopathy according to the Psyc

Aristocratic Landscape : The Spatial ideology of the Medieval Aristocracy

The purpose of the book is to be a comparative study of how the aristocracy in Western Europe organised space and landscape, especially inside and adjacent to their residences. This comparison will involve examples from Britain, France, Germany and Scandinavia and is concentrated to the period c. 800-1500. The overall aim is to search after a common aristocratic spatial ideology and to explain its
