The relationship between the two lichen species Xanthoria calcicola and X. parietina was investigated at genetic level, comparing the ITS regions of the rDNA. The extracted DNA was amplified with the primers ITS4 and ITS5 in a PCR and automatically sequenced. The variation within the separate species was smaller than the variation between the species. Compared to a third species, X. elegans, the v
The tropospheric mixing ratio profile of ethylene (C2H4) has been retrieved from a high spectral resolution ground-based infrared solar absorption spectrum. The spectrum was recorded during intense fires in New South Wales, Australia on January 1, 2002, and was analyzed with the C2H4 spectral parameters added to the 2000 HITRAN compilation. Absorption by C2H4 in the smoke-affected spectrum extends
The new heterocyclic spiro terpenoid niveulone (1) was isolated from the cultural fluid of the ascomycete Dasyscyphus niveus, and its chemical structure and relative configuration were determined by spectroscopic techniques.
Reviews the film, Requiem, directed by Hans-Christian Schmid (2006). This award-winning (for both its star, Sandra Hüller, and the film itself) German film is based on the case of Anneliese Michel, a 23-year-old German woman who died in 1976, probably of starvation (she weighed 68 lb. just before her death) and exhaustion, after 67 exorcism rites. Hüller's nuanced performance chills the spine far
The possibility of using high hydrostatic pressure (HHP) to modify the physico-chemical properties of dietary fibre polysaccharides in white cabbage (Brassica oleracea var. capitata) was studied. Two cultivars (Heckla and Predikant) were subjected to high pressure treatment (400 and 500 MPa) at different temperatures (20, 50 and 80 °C). The total dietary fibre (TDF) content was only slightly affec
We investigate spin-dependent transport properties of two-dimensional electron systems modulated by both the stray field from a ferromagnetic metal (FM) stripe and the electrostatic potential (EP) provided by two normal metal Schottky stripes which sandwich the FM stripe. The EP consists of a single barrier and a single well. By switching the gate voltages applied to the Schottky stripes, the barr
Isolated Ca2+-binding EF-hand peptides have a tendency to dimerize. This study is an attempt to account for the coupled equilibria of Ca2+-binding and peptide association for two EF-hands with strikingly different loop sequence and net charge. We have studied each of the two separate EF-hand fragments from calbindin D-9k. A series of Ca2+-titrations at different peptide concentrations were monitor
An economy consisting of n>=2 different types of consumers and one publicly owned natural monopoly is under consideration. The preferences of the consumers are assumed to be linear in money and the demand curves are assumed not to cross. We also suppose that the net utility from consumption is so high that we do not have to consider the individual rationality constraints. Given these assumptions,
Regulatory T cells (Tregs) participate in the control of the immune response. In the human system, an IL-10-secreting, T regulatory type 1 cell (Tr1)-like subset of Tregs can be induced by concurrent cross-linking of the TCR and CD46 on naive CD4(+) T cells. Because many viral and bacterial pathogens, including the major human pathogen Streptococcus pyogenes, bind to CD46, we asked whether this ba
We present a theoretical study of the mesoscopic fluctuations of g tensors in a metal nanoparticle. The calculations were performed using a semirealistic tight-binding model, which contains both spin and orbital contribution to the g tensors. The results depend on the product of the spin-orbit scattering time tau(so) and the mean-level spacing delta, but are otherwise weakly affected by the specif
This study concerns the possibilities of using microwave-assisted extraction (MAE) or supercritical fluid extraction (SFE) for detection of harmful azo colorants in leather. After degreasing of the leather sample with SFE there follows a reductive cleavage of the azo colorants to their corresponding aromatic amines in the MAE or SFE equipment. The aromatic amines are subsequently extracted using e
VAX/VMS programs for predicting protein hydropathy from amino acid sequence with several parameters are described. The hydropathy propensities of amino acids were normalised to make the different scales and predictions comparable. Another program package can be used to study similarity on the secondary structural level by comparing, for example, hydropathy predictions. These methods can provide va
The aim was to study postures and movements during repetitive work using video-based observations and direct technical measurements (inclinometers and goniometers). A total of 21 healthy women from a poultry processing plant volunteered. Neck flexion > 20 degrees was registered during 92% of the recorded time with the observation method, while the corresponding value measured with the inclinometer
