A new signal processing method for the detection of cyclic variations in atrial fibrillation frequency is presented. The objective was to investigate whether or not respiration, through the autonomic nervous system, modulates the fibrillation frequency in patients with permanent atrial fibrillation. A group of eight patients with permanent atrial fibrillation, atrioventricular block III and a perm
The effects of energy conservation and saturation are studied in the coordinate space dipole formulation for QCD cascades. Preliminary results for dipole-dipole and dipole-nucleus scattering are presented. Very large effects are obtained from energy conservation, corresponding to a factor similar to 10 in the cross section and similar to 3 in lambda(eff). Some results on the gluon fusion process g
The molecular mobility in a hexagonal DNA-cationic surfactant complex is studied using H-1 and C-13 nuclear magnetic resonance spectroscopy. The charge-compensated complex can swell in water up to a content of approximately seven water molecules per charge. The NMR measurements show that in the dry state the alkyl chains of the surfactant have the properties of a disordered solid with internal mot
We previously identified a positive transcriptional element identical to human Ha-ras response element ( HRE) within the promoter of the rat Ha-ras gene. We further identified CArG binding factor A ( CBF-A), a member of heterogeneous nuclear ribonuclear protein ( hnRNP) gene family, as a trans-acting factor that binds the HRE sequence with high affinity in rat mammary carcinoma cells. To determine
Eleven species of common fungi from compost were analysed for their content of ergosterol and phospholipid fatty acids (PLFAs) after growth on agar media. Mean content of ergosterol was 3.1 mg g(-1) dw of fungal mycelium (range 1-24 mg g(-1) dw). Total amount of PLFAs varied between 2.6 and 43.5 mumol g(-1) dw of fungi (mean 14.9 mumol g(-1) dw). The most common PLFAs were 16:0,18:2omega6,9 and 18

In this work, a numerical study has been performed to simulate the unsteady fluid flow and heat transfer in a transonic high-pressure turbine stage. The main objective of this study is to understand the unsteady flow field and heat transfer in a single transonic turbine stage using an unsteady structured Navier-Stokes solver. For the time accurate computation, a fully implicit time discretization,
This theme is concerned with the relevance and efficacy of educational methods adopted in dental schools while recognizing the influence of geopolitical issues in different countries and regions. Particular emphasis will be given to examples of best practices and innovations. Cognition and learning are dealt with in many different research areas such as education, psychology, cognitive sciences, b
The paper treats jitter estimation for alignment of a set of signals which contains several unknown classes of waveforms. The motivating application is epileptic EEG spikes. where alignment prior to clustering and averaging is desired. The assumption that the signal waveforms are unknown precludes the use of classical techniques, notably matched filtering. Instead we treat two other classes of met
The interregional traveller’s preferences of railway stations, their service provision and location, are of interest in the discussion of station reinvention brought on by the introduction of high speed train traffic. A railway station is created by station as well as societal agents, and can be described as a synthesis of symbolic value, location, traffic, services and stationscape. Traveller pr
In spite of the importance of legumes in Latin American diets, nutritional features of carbohydrates in these seeds are scarcely known. The purpose of this study was to assess the in vitro digestibility of starch in cooked powdered black beans, a common type of product in Mexico and Central America. The properties of a commercial product were compared to those of an experimental material obtained
Romans 2 has long been a crux interpretum. Among matters of dispute is the function and identity of Paul’s interlocutor(s) in the chapter. While scholars agree that the individual addressed in 2:17–29 is a Jew, there is no such consensus with respect to the identity of the person addressed in 2:1–5. On the one hand, the scholarly majority holds that this person is depicted as a Jew and that the sa

The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They produce and secrete histamine and chromogranin A-derived peptides in response to circulating gastrin. Mobilized histamine stimulates acid secretion from adjascent parietal cells. The aims of the present investigation were to assess the usefulness of gastric submucosal microdialysis in studies of EC
