Drawing, effective

The aryl migration undoubtedly occurs as a result of the strong electron with drawing effect of the four fluorine atoms. 

The foregoing results indicate that a powerful anchimeric rate-accelerating effect (38) must operate in the transition state of the electrophilic substitutions of II which exceeds the electron-with drawing effect of the immonium form D in the mono-positive cation II ...

The electron deficiency of the carbonyl group may be relayed through a double bond of an a,p-unsaturated ketone to the P-position. The addition of a carbon nucleophile to the p-position of an a,P-unsaturated ketone is known as a Michael addition. Since both the electron-with-drawing effect and the activating effect of the carbonyl group of phorone may be relayed through the separate double bonds, a further base-catalysed reaction can occur. This involves a Michael addition and leads to cyclization and the formation of isophorone (Scheme 3.81). 

DilFerences ma also be due to the condition of the valve after it has been in service for a time. For example, a Class valve can he quickly turned into a Class II valve tor worse) by erosion due to abrasive solids, cavitation, or the wire drawing effects of flow across valve seats vhen the valve is sluu ofl or nearly so.

In the photoageing of polycarbonates, photo-oxidation has been shown to be a more important process than the photo-Fries reaction. The photo-oxidation of epoxy-resins has been found to depend on the type of hardener and its concentration. A correlation has been observed between the changes in chemical structure and thermally stimulated current of poly(vinyl alcohol) during photo-oxidation. Other studies of interest include the weathering of polymers outdoors,effect of ozonation on polymers, effect of drawing, effect of biodegradation, and changes in mechanical properties of thermoplastics. ... 

Although it is not possible to draw effective conclusions about Morlet wavelet from the signal in the time domain, these graphs can be useful to check the consistency of data and to have a first understanding of the data.

Significantly, the Four Capabilities Model dismisses the idea of a complete leader, an individual with equal skill in all four areas, and recognises instead that leaders need to be adaptive and recognise their own strengths and weaknesses. In this way, they are able to draw effectively on the skills and knowledge of those around them. This is particularly important in engineering contexts, where solutions often depend on interdisciplinary collaboration and the combination of technical expertise across teams.
