Fragmentation of the SF6 molecule upon F 1s excitation has been studied by resonant photoemission. The F atomiclike Auger line exhibits the characteristic Doppler profile that depends on the direction of the photoelectron momentum relative to the polarization vector of the radiation as well as on the photon energy. The measured Doppler profiles are analyzed by the model simulation that takes accou
Study Design. A randomized controlled comparative trial with an 8-month follow-up period was conducted. Objective. To compare the effect of the McKenzie treatment method with that of intensive dynamic strengthening training in patients with subacute of chronic low back pain. Summary of Backround Data. Randomized studies indicate that the efficacy of the McKenzie method in the treatment of patients
We studied prospectively the change over ten years in mortality, walking ability and place of residence after a hip fracture in 753 patients in Japan. We compared the deaths observed in these patients with those expected in the general population, matched for age, gender and calender year at the time of fracture. The survival rate decreased dramatically for two years after the event and the mortal
We investigated the species richness of vascular plants at the scale of 5 3 5 km in the Swedish province of Harjedalen, and the relationship between richness and environment. Environmental variables included geographical, altitudinal, topographical, bedrock, soil type, and land-cover descriptors. The species richness was subdivided into groups of species with similar life-form, i.e. trees, dwarf s
The basic precondition for color vision is the presence of at least two receptor types with different spectral sensitivities. The sensitivity of a receptor is mostly defined by the opsin-based visual pigment expressed in it. We show here, through behavioral experiments, that the nymphalid butterfly Heliconius erato, although it expresses short and medium wavelength opsins and only one long wavelen
The strategies of development in rural territories in the provinces of Jujuy, Misiones and Salta in Argentina provide the objects of study in this analysis. These three cases reveal that there has been a process of consolidation of grass-roots organization since 1990, which seems to have strengthened the historically marginalized sectors of the population. New kinds of relationships between the st
Eight patients with colloid cysts of the third ventricle were examined with CT and MR. In six, surgical resection was performed and the material was subjected to histologic evaluation; the concentrations of trace elements were determined by particle-induced X-ray emission. Stereotaxic aspiration was performed in two. The investigation showed that colloid cysts are often iso- or hypodense relative
The Pegomya terminalis species group is redefined on the basis of the characteristic, exceptionally long and apically strongly depressed female oviscapt. A North American species has once been reared from horsetail (Equisetum sp.), and it is believed that all the species in this group as larvae feed on this unusual diet. The present paper reviews the known Palaearctic species with an identificatio
We consider the following problem from swarm robotics: given one or more "awake" robots in some metric space M, wake up a set of "asleep" robots. A robot awakens a sleeping robot by moving to the sleeping robot's position. When a robot awakens, it is available to assist in awakening other slumbering robots. We investigate offline and online versions of this problem and give a 2-competitive strateg
BB rats develop various organ-specific autoimmune diseases, e.g. autoimmune diabetes and thyroiditis and have proven important to dissect genetic factors that govern autoimmune disease development. The lymphopenia (lyp) gene (iddm2) is linked to autoimmune disease development and is a major genetic difference between diabetes-resistant (DR) and diabetes-prone (DP) BB rats. To study the effects of
Aims/hypothesis Genetic and epidemiological studies suggest an association between gestational diabetes mellitus and type 2 diabetes. Both are polygenic multifactorial disorders characterised by beta cell dysfunction and insulin resistance. Our aim was to investigate whether common genetic variants that have previously been associated with type 2 diabetes or related phenotypes would also confer ri
Key design features of high performance houses are investigated for improving energy efficiency in cold climates. Reference dwellings with typical constructions and system designs are compared with high performance houses using the best technology available. The dwellings used for reference are a multi-family apartment building and a single-family detached house, designed according to a mix of Nor
The Jonkoping Anorthositic Suite (JAS) in S. Sweden has characteristics typical for (Proterozoic) massif-type anorthosites. The interstitial liquid of these plagioclase-porphyritic rocks solidified at 1,455 +/- A 6 Ma, as determined by U-Pb isotope analysis of baddeleyite. The JAS developed during a regional 1.47-1.44 event in Fennoscandia that generated widespread mafic magmatism (basalts, and di
Dilute solutions of -lactoglobulin (-Lg) A, B, and C were heated in phosphate buffer at temperatures between 40 and 94 C for 10 min, cooled, and analyzed using near-UV and far-UV circular dichroism (CD). The decrease in near-UV CD intensity at 293 nm (293) could be analyzed in terms of a two-state model, and the stability was -Lg C > -Lg A > -Lg B on the basis of the midpoint temperatures for samp
Collagen VI assembly is unique within the collagen superfamily in that the alpha 1(VI), alpha 2(VI), and alpha 3(VI) chains associate intracellularly to form triple helical monomers, and then dimers and tetramers, which are secreted from the cell. Secreted tetramers associate end-to-end to form the distinctive extracellular microfibrils that are found in virtually all connective tissues. Although
Ecotoxicological endpoints based on behavioral traits (e.g., predator avoidance, feeding, and locomotion) may be more sensitive and give more insights into patterns of sublethal toxicity than survivorship tests. In this study, the density-dependent grazing rate of Daphnia pulex pre-exposed to p,p'-dichlorodiphenyldichloroethylene (DDE) (insecticide metabolite) and glyphosate (herbicide), via water
Laser-induced fluorescence has been used for detection of CO in different environments. The fluorescence light was obtained by using a two-photon transition between theX1?- and theB1?- electronical states around 230 nm. Cell measurements indicate a detection limit lower than 0.1 ppm. Measurements in a CH4/air flame and in a low pressure dc discharge were realized with a diode-array detector, which
OBJECTIVE: The influence of the gastrointestinal (GI) microflora in patients with irritable bowel syndrome (IBS) has not been clearly elucidated. This study was undertaken to see if patients with IBS have an imbalance in their normal colonic flora, as some bacterial taxa are more prone to gas production than others. We also wanted to study whether the flora could be altered by exogenous supplement
A numerical scheme based on the volume of fluid (VOF) method for predicting the displacement of one liquid by another has been verified versus electrical resistance tomography (ERT) and ultrasonic velocity profile (UVP) measurements for the displacement of yoghurt by water. The scheme using the VOF method predicts the skewed phase distribution as measured using ERT and the global structure of the
