Border zones between normal and ischemic tissue have been implicated as a cause of arrhythmic cardiac activity. A variety of experiments with coupled cells and strips of tissue has been designed to understand the arrhythmogenic effects of border zone currents. In this paper, we use systems of differential equations to model an ischemic (depolarized) cell (or region) coupled to a normal cell und...

This paper is a synthesis of the results from the project INTEWON and related studies. The link between the physiological thermoneutral zone (TNZ) and the thermal comfort zone (TCZ) is discussed. Secondly, we discuss the relation between thermal preference and thermal sensation and how physiological parameters, such as skin temperature can predict thermal sensation. It is shown that the identif...

Zone analysis (ZA) is a natural language processing (NLP) technique the application of which include document screening, citation analysis, and information extraction (IE). With a huge volume of biological work now available in archived articles and abstracts and a critical need for an effective use of the information contained, we aim to provide a technique for pinpointing and organizing exper...

The aims of this study were (i) to describe the relative intensity of simulated tennis play based on the cumulative time spent in three metabolic intensity zones, and (ii) to determine the relationships between this play intensity distribution and the aerobic fitness of a group of competitive players. 20 male players of advanced to elite level (ITN) performed an incremental on-court specific en...

Complex spike activity of floccular Purkinje cells responds to patterns of rotational optic flow about the vertical axis (rVA neurons) or a horizontal axis 45 degrees to the midline (rH45 neurons). The pigeon flocculus is organized into four parasagittal zones: two rVA zones (zones 0 and 2) interdigitated with two rH45 zones (zones 1 and 3). Climbing fiber input to the rVA and rH45 zones arises...

UNLABELLED During the last decade discussion about training-intensity distribution has been an important issue in sports science. Training-intensity distribution has not been adequately investigated in speed skating, a unique activity requiring both high power and high endurance. PURPOSE To quantify the training-intensity distribution and training hours of successful Olympic speed skaters ove...

OBJECTIVE dimensional guidelines for bedrails have been developed to minimise the risk of patient entrapment within the bed. We examined whether bedrails in a large Irish teaching hospital complied with these standards. DESIGN AND SETTING survey of 60 accessible beds in six hospital wards. METHODS a specialised cone and cylinder tool that mimics the size and weight of a small adult neck and...
