In the wide field of applications, a visibility level VL = 3 - 60 is recommended. For our recognition task, we are obliged to take into account that our random conditions are far from the experimental conditions of the basic researches (Young test person with a high visus under ideal environmental conditions) [4]. Furthermore in our case we have a more difficult visual searching task. Parameter variations as the increase of presentation time from 0,2 to 1.0 s. and the detection propability from 50% to 100% are taken into account [5] In spite of the gliding variations of the parameters as well as the visibility level, for simplification let us assume VL = 10 as minimum requirement. 

Over the range of fit, matching the dependence of Oj on a produces only a numerical coefficient and does not constitute a test of the predicted dependence of the modulus on either T or Mj,. We have already confirmed that Young s modulus actually does increase with temperature for elastomers. Next let us...

Asthma affects 3—5% of the population and is one of the most common chronic illnesses (7—9). Both the frequency and severity of asthma appear to be increasing (10—13). Acute, severe asthma has the potential to be fatal. The disease may first appear ia childhood and iadividuals so affected can suffer recurrent episodes throughout their Hves or they may "outgrow" the condition at puberty. On the other hand, there is also adult-onset asthma. These people show no symptoms as children or as young adults, but suddenly develop symptoms later ia life. There have been many reports of bronchial infections preceding the appearance of asthma. However it is not known whether these infections contributed to the development of the disease or whether iadividuals who are already predisposed to asthma ate more likely to experience bronchospasms as a result of a bronchial infection (14). 

Moduli and Poisson s Ratio. The Young s modulus of vitreous sihca at 25°C is 73 GPa (<1.06 x 10 psi), the shear modulus is 31 GPa (<4.5 X 10 psi), and the Poisson s ratio is 0.17. Minor differences in values can arise owing to density variations. The elastic modulus decreases with increasing density and Poisson s ratio increases (26).
