In this paper, we present a detailed experimental study of turbulence chemistry interactions in the "DLR_B" turbulent jet diffusion flame. The flame operates on mixtures of CH4, H-2, and N-2 in the fuel stream at Re = 22,800 and is a target flame within the TNF workshop. Extinction and re-ignition events can be tracked in real time and related to the underlying flow field phenomena and temperature

Intrastriatal transplantation of embryonic dopaminergic neurons is currently explored as a restorative cell therapy for Parkinson disease (PD). Clinical results have varied, probably due to differences in transplantation methodology and patient selection. In this review, we assess clinical trials and autopsy findings in grafted PD patients and suggest that a minimum number of surviving dopaminergi

"Tidskrift för politisk filosofi" nr 2/2003 innehåller en kritisk granskning av Larry Temkins inflytelserika bok "Inequality" från 1993. Författarna, Ragnar Francén, Jonas Gren och Niklas Juth, underkastar Temkins komplexa, flerdimensionella form av egalitarism en noggrann undersökning. Deras kritiska synpunkter är väl värda läsarens uppmärksamhet.

Acute airway obstruction during oral intake is a relatively common event that may be fetal if not relieved immediately. Deglutition was studied in 75 individuals who had experienced a near-fatal choking episode (NFCE) or sudden inability to breathe during food intake that was promptly relieved by means of a Heimlich maneuver, suctioning, or intubation. Videofluoroscopy supplemented by static imagi

Complex nanostructures are becoming increasingly important for the development of nanoscale devices and functional nanomaterials. Precise control of size and morphology of these structures is critical to their fabrication and exploitation. We have developed a method for stepwise growth of tree-like nanostructures via the vapour liquid-solid (VLS) growth mode, demonstrated for III-V semiconductor m

I denna rapport redovisas preliminära resultat av frysprovning och kapillärsugning hos tre typer av gotländsk kalkbunden sandsten.

Stimulation of human fibroblasts by platelet-derived growth factor (PDGF)-BB leads to a down-regulation of PDGF beta-receptors and a concomitant appearance of intracellular granular accumulations of receptors, as determined by stainings with the mAb PDGFR-B2. The granules contained both the ligand and PDGF beta-receptors, as revealed by double-immunofluorescence staining, and were formed in respon

The ability of different lactic acid bacteria to influence the physicochemical characteristics (content, viscosity and molecular weight) of dietary fibre in beta-glucan-rich barley and oat concentrates was investigated. The cultures used were Lactobacillus acidophilus and the exopolysaccharide producing strain Pediococcus damnosus 2.6, together with the yoghurt culture, V2 (a mixture (1:1) of Lact

Summary: The rheumatoid shoulder and elbow should be assessed in an early stage concerning the possibility of surgical intervention. The cause of the shoulder pain can be localized elsewhere in the shoulder girdle or in the neck. In patients with glenohumeral pain, resurfacing of the humeral head with a cup seems to be a good alternative to conventional stemmed prostheses. It diminishes the risk o

A bowel labeling agent is important for improving abdominal MR. Besides providing contrast between the bowel and other organs, the contrast agent itself is a potential source of artifacts. The artifacts created by superparamagnetic particles (SPP) subjected to motion have been studied in vitro at 0.5 T, and compared to artifacts created by a paramagnetic compound. Apart from the expected static ef

Recension av Andy Dougan, Dödsmatchen – fotboll i nazismens skugga.

By using arrays of nanowires with intentionally broken symmetry, we were able to detect microwaves up to 110 GHz at room temperature. This is, to the best of our knowledge, the highest speed that has been demonstrated in different types of novel electronic nanostructures to date. Our experiments showed a rather stable detection sensitivity over a broad frequency range from 100 MHz to 110 GHz. The

High-pressure investigations of titanium pyrophosphate, TiP2O7, in diamond anvil cell have been performed at room temperature using in situ Raman scattering and Fourier transform infrared spectroscopy (FTIR). The endeavor was to acquire information on pressure-induced structural transformations such as phase transitions and amorphization occurring in the crystal lattice. The pressure-stimulated al

Background: In most clubfoot studies, the outcome instruments used are designed to evaluate classification or long-term cross-sectional results. Variables deal mainly with factors on body function/structure level. Wide scorings intervals and total sum scores increase the risk that important changes and information are not detected. Studies of the reliability, validity and responsiveness of these i

Glukosamin ingår i glykosaminoglykaner i ledbrosk och synovialvätska. Tidigare gavs glukosamin som kosttillskott, men det klassificeras numera som ett icke-steroidliknande, antiinflammatoriskt läkemedel. Det beror på att flera kliniska studier har visat att glukosamin kan ge symtomlindring hos en del patienter med lätt till måttlig knäartros. Det brukar ta 2 - 4 veckor innan symtomlindringen kan m

Soil C effluxes were measured at five forest stands with different vegetation and a meadow in southeastern Sweden (57¡5«N, 16¡7«E). Exponential regressions of soil respiration against air and soil temperatures were used to model soil respiration at forests stands. For the meadow, a light response curve with gross primary production (GPP) against PAR and a cubic regression with GPP against air temp
