Elemental abundance trends in the Galactic thin and thick disks as traced by nearby F and G dwarf stars

Based on spectra from F and G dwarf stars, we present elementalabundance trends in the Galactic thin and thick disks in the metallicityregime -0.8< [Fe/H < +0.4. Our findings can besummarized as follows. 1) Both the thin and the thick disks show smoothand distinct abundance trends that, at sub-solar metallicities, areclearly separated. 2) For the alpha -elements the thick disk showssignatures of c

Extremal Control of Wiener Model Processes

Extremal control of Wiener type processes is considered. These models consists of a linear part followed by a static nonlinearity. We will consider nonlinearities having one extremum point. The purpose is to keep the output of the process as close as possible to the extremum point. The main problem in the control of this kind of processes is the non-uniqueness of the inverse of the nonlinearity. T

Statistical evaluation of cell kinetic data from DNA flow cytometry (FCM) by the EM algorithm

Flow cytometric DNA measurements yield the amount of DNA for each of a large number of cells. A DNA histogram normally consists of a mixture of one or more constellations of G0/G1-, S-, G2/M-phase cells, together with internal standards, debris, background noise, and one or more populations of clumped cells. We have modelled typical DNA histograms as a mixed distribution with Gaussian densities fo

Topical nitroprusside may reduce histamine-induced plasma exudation in human nasal airways

Mucosal exudation of nonsieved bulk plasma is a key feature of airway defense and inflammation. We have previously observed in guinea pig tracheobronchial airways that endogenous nitric oxide (NO) of the mucosa may tonically suppress the permeability of the subepithelial microcirculation, and that topical administration of the NO donor nitroprusside may reduce plasma exudation responses. The prese

Percutaneous transvenous mitral annuloplasty - Initial human experience with device implantation in the coronary sinus

Background - Mitral annuloplasty is the most common surgical procedure performed for ischemic mitral regurgitation (MR). Surgical mitral annuloplasty is limited by morbidity, mortality, and MR recurrence. We evaluated the safety and feasibility of a transvenous catheter-delivered implantable device to provide a percutaneous alternative to surgical mitral annuloplasty. Methods and Results - Five pa

Pathway-specific bidirectional regulation of Ca2+/calmodulin-dependent protein kinase II at spinal nociceptive synapses after acute noxious stimulation.

An intensely painful stimulus may lead to hyperalgesia, the enhanced sensation of subsequent painful stimuli. This is commonly believed to involve facilitated transmission of sensory signals in the spinal cord, possibly by a long-term potentiation-like mechanism. However, plasticity of identified synapses in intact hyperalgesic animals has not been reported. Here, we show, using neuronal tracing a

Accessibility indices and planning theory

Accessibility is an important factor in land-use planning and several methods have been developed to calculate and to predict it. Nevertheless, it is seldom applied in planning situations, maybe because many land-use planners and elected officials lack the knowledge and resources needed to use traffic models. Consequently, accessibility is often used as a concept and a goal in daily planning, but

Dual-broadband rotational CARS thermometry in the product gas of hydrocarbon flames

Coherent anti-Stokes Raman spectroscopy (CARS) is an established technique for gas-phase thermometry in combustion. In this work, rotational CARS in the dual-broadband approach has been investigated for flame thermometry in the product gas of ethylene/air flames in a wide range of equivalence ratios (0.5 < phi < 2.5). The nitrogen lines dominated the rotational CARS spectra in the whole equivalenc

Prostate specific antigen and human glandular kallikrein 2 in early detection of prostate cancer

Purpose: Several tumor markers have recently been applied for prostate cancer screening. We analyze the effectiveness of prostate specific antigen (PSA), age specific PSA, PSA velocity, volume adjusted PSA densities, change in PSA level following antibacterial therapy, free-to-total PSA ratio, alpha1-antichymotrypsin bound PSA, alpha2-macroglobulin bound PSA, alpha1-protease inhibitor bound PSA an

Development of Zonal Models for Analysis of Engine Knock

Autoignition in SI engines is an abnormal combustion mode and may lead to engine knock which is an undesired phenomenon in SI engines. It may cause damage and it is a source of noise in engines. Knock limits the compression ratio of the engine and a low compression ratio means low fuel conversion efficiency of the engine. This thesis presents a theoretical investigation about the modeling of the e

Impact of climate change on the population dynamics of Ips typographus in southern Sweden

Mass-propagation of the spruce bark beetle, Ips typographus, following windfalls and drought is a serious threat to mature spruce forests. Climate change will affect the population dynamics of I. typographus directly as the swarming activity and development rate are mainly controlled by temperature, and indirectly via changes in availability of brood trees. Today, I. typographus is in general univ
