Fear parameter

This choice implies that the fear parameter of the prey equals its preference parameter 6 for the open habitat 1 where the predators are lurking A plausible explanation for this choice could be, for instance, that food for the prey is better in the dangerous habitat 1. Furthermore a specific saturation level yo = 1 is chosen. 

Others (respiration, fear, reactivity to touch) are scored in 2 directions. Finally, certain parameters (rectal temperature, pupil diameter) are measured quantitatively. 

More elaborate procedures can be employed to assess whether drug withdrawal induces changes in fearfulness, pain sensitivity, convulsive threshold or even memory. On the other hand, it is frequently difficult to demonstrate effects on these parameters and the tests involved are particularly time-consuming. The procedure described below represents an initial screen which has been shown to be sensitive to several dependence-inducing drugs such as opioids and benzodiazepines (Goudie et al. 1993). 

Traces of polar impurities as well as water can change solvent polarity considerably [122], It is feared that small traces of water will have a strong impact on a parameter determination with Reichardt s dye [124], The influence of water on the solvatochromic shift of Reichardt s dye in [C4mim][PF6] has been investigated. The more water that is added the shorter the wavelength of the absorption maximum [104], This had been made use of in determining water content of samples. 

At this time it is too early to predict the impact of the Fear Phase or how long it will last. Environmental health and safety research results are published on a daily basis and often appear to be conflicting due to differences in nanomaterial structure, purity, temperature, cell type (if studied in vivo), residence time in the body, soil conditions, inter-laboratory variability, and various other parameters. These differences often go undetected by the media and, until results of further studies are reported, may produce unwarranted public concern or, conversely, unwarranted positive acceptance.
