BACKGROUND Grouping behaviour, common across the animal kingdom, is known to reduce an individual's risk of predation; particularly through dilution of individual risk and predator confusion (predator inability to single out an individual for attack). Theory predicts greater risk of predation to individuals more conspicuous to predators by difference in appearance from the group (the 'oddity' e...

Production planning in mineral exploitation should be undertaken to maximize exploited ore at a minimum unplanned dilution. Unplanned dilution reduction is among the ways to enhance the quality of products, and hence, reduce the associated costs, resulting in a higher profit. In this way, firstly, all the parameters contributing to unplanned dilution in underground stopes and specifically the c...

in animals are potential anti-predator benefits, including the many-eyes effect, predator confusion, the dilution of individual risk of being caught when part of a large group, and the selfish herd effect (Krause & Ruxton 2002). The many-eyes effect postulates that an increased number of potential prey individuals scanning for predators are more effective at detecting their approach, and this e...

BACKGROUND: Measurement of cardiac output and extravascular lung water in critically ill patients using femoral artery double-indicator dilution involves femoral artery catheterization. The potential risk of vascular compromise to the limb may be exacerbated in patients receiving vasopressors. The utility of scanning laser Doppler flowmetry to measure changes in pedal perfusion following cathet...

Well vulnerability maps can be used to quantify the potential impact of contaminant sources on a well or well field. Well vulnerability can be expressed in terms of the expected contaminant concentration in the extracted well water and the time history of these concentrations, thus accounting for dilution in the well by mixing with clean water. The information contained in the vulnerability map...

Clinical pathology testing of rodents is often challenging due to insufficient sample volume. One solution in clinical veterinary and exploratory research environments is dilution of samples prior to analysis. However, published information on the impact of preanalytical sample dilution on rodent biochemical data is incomplete. The objective of this study was to evaluate the effects of preanaly...
