The degree to which his upbringing at Port-Royal inspired Racine's tragic vision is a question unlikely to be answered with any precision, given the other influences exerted on him, such as those of Greek and Roman tragedy, the Bible, and life itself.
Even though the layers were once horizontal, the tremendous pressures exerted on them were such that they emerged in a vertical array, with folds so tight they almost look like ripples in soft fabric rather than unforgiving rock.
The influence of these design factors on the maximum load during the forming operation and the pressure exerted on the tooling such as the punch and the mandrel is investigated and summarized in terms of the maximum forming force.
When pressure is exerted on a tooth, such as during chewing or biting, the tooth moves slightly in its socket and puts tension on the periodontal ligaments.
The latter is likely to contribute to certain anti-TNF effects exerted on immune cells such as migratory inhibition [ 3] and increased apoptosis [ 4].
During chronic infection in CF, strong selective pressure is exerted on bacterial pathogens such as Pseudomonas aeruginosa and S. aureus, especially during treatment with tobramycin, ciprofloxacin and colistin, leading to discernable variations in the clonal lineages [ 23].
The lytic activity is also exerted on other cells, such as A20, a B cell lymphoma [ 9], Caco-2 cells [ 11], J774 [ 12], Jurkat [ 13], and HepG2 cells [ 14].
In other societies, however, changes in social organization exerted pressure on such groups, which were ultimately forced to surrender their land to increasingly powerful and autocratic chiefs.
The duplicated secretory virulence factors of Xylella fastidiosa (LesA, LesB and LesC), implicated in Pierce's disease of grape and citrus variegated chlorosis of citrus species, epitomizes the positive selection pressures exerted on advantageous genes in such pathogens.
That office, which began in 1801, was first an appendage of the Home Office and the Board of Trade, but by the 1850s it had become a separate department with a growing staff and a continuing policy; it was the means by which discipline and pressure were exerted on the colonial governments when such action was considered necessary.
