The decision to begin eating or to stop eating is a complex process. Hunger is primarily driven by hunger signals, like ghrelin and neuropeptide Y, originating from the gastrointestinal tract and from the hypothalamus. The hunger signals stimulate the seeking of food and the eating, being activating for the body and mind. Thirty minutes after the start of eating, satiety signals arise from the int

Background: Smoking is the major risk factor for cardiac events in younger women and is most common in groups with the least favourable socioeconomic circumstances. Objective: To assess to what extent geographical differences in the female incidence of myocardial infarction in the city of Malmo in Sweden can be accounted for by smoking and to what extent intra-urban variances of smoking are relate

A packed bed bioreactor, with 170 ml glass bead carriers and 130 ml medium, was tested for the removal of the endocrine disrupter, nonylphenol, with a Sphingomonas sp. The bioreactor was first continuously fed with medium saturated with nonylphenol in an attempt to simulate groundwater pollution. At best, nonylphenol was degraded by 99.5% at a feeding rate of 69 ml h-1 and a removal rate of 4.3 mg

In our previous paper [M.A. Borowiak, M.H. Jamroz, R. Larsson, J. Mol. Catal. A: Chem., 139 (1999) 97], an impulse-oscillation model (IOM) was used for a time description of catalytic acts in the reactions of catalytic decomposition of formic acid on oxide catalysts for unimolecular mechanism. In this paper: the bimolecular mechanism were modelled for the same reactions. The results of IOM calcula

BACKGROUND: SRY (sex-determining region, Y) is the gene responsible of gonadal differentiation in the male and it is essential for the regular development of male genitalia. Translocations involving the human sex chromosomes are rarely reported, however here we are reporting a very rare translocation of SRY gene to the q -arm of a deleted X chromosome. This finding was confirmed by cytogenetic, fl

To link aesthetics to traffic safety, the field of environmental psychology was consid-ered. A new model of driving behaviour was developed, based on Lewin’s (1951) equation, B = f (P,E) and by employing Küllers’ (1991) model of the basic emotional process. The employed model B = f (R(Road), U(Users), A(Task), P(Person)), states that driving behaviour (B) is related to the physical environment (R)

Solute transport in the unsaturated zone is a complex process. The first of the two objectives for this study was to examine how it could be conceptualized under different flow conditions. The second objective was to investigate how the time domain reflectometry (TDR) technique should be used in order to obtain high quality data from the soils studied. The TDR is an accurate instrument for water c
