“…The poly(aryl ether ketone) type polymers are a class of high performance engineering thermoplastics which has a variety of applications, such as in aircraft and automobile industries. 1 The most widely used material of this class is poly(ether ether ketone) [PEEK] which has very good thermal, mechanical and chemical stability. One of the drawbacks of PEEK is its insolubility in common organic solvents, which inhibits its chemical modification.…”

Neste trabalho, três derivados do poli(éter éter cetona) [PEEK] foram preparados em suspensão por meio da nitração, redução para o grupo amino e redução da carbonila. Os polímeros modificados foram caracterizados por espectroscopia de infravermelho (FTIR), Ressonância Magnética Nuclear (NMR), análise termogravimétrica (TGA) e apresentaram características interessantes para a preparação de membranas e compósitos, tais como, basicidade e solubilidade em solventes orgânicos, como DMF.In this study, three derivatives of poly(ether ether ketone) [PEEK] were prepared in suspension by nitration (NO 2 -PEEK), reduction to the amino group (NH 2 -PEEK) and carbonyl reduction (PEEK-OH). These modified polymers were characterized by NMR, IR spectroscopy and thermogravimetric analysis. They showed interesting characteristics, such as, basicity and higher solubility in organic solvents, like DMF, for use as membranes and composites in different applications.

“…With Alexander the Great, theatrical activity continued to expand throughout the Mediterranean and especially across the newly enlarged Hellenistic world. 78 We have not only accounts of various festivals featuring dramatic performances (several islands, for example, held a Dionysia, including Chios, Lemnos, and Paros), 79 but also reports of various people involved with theatre, such as the many associations of Artists of Dionysus, which were briefly discussed above. 80 The evidence for theatrical activity similarly increases, ranging beyond the literary to include a wider range of epigraphic and archaeologic material.…”

On unconscious inhibition: Instantiating repression in the brain

In psychodynamic theory, repression is a major neurotic defence mechanism, which operates by separating the drive investment from the conflictual representation. While major insights in unconscious processing have recently been obtained in the cognitive neurosciences, repression as a psychological mechanism remains controversial. In this chapter, we present empirical results obtained with subliminal priming paradigms concerning unconscious inhibition of (1) mental representations and (2) motor control. For these paradigms, we propose that only under very stringent subliminal conditions where stimuli are completely undetectable, the dynamics of deep unconscious processing -which are structurally sensitive to subject factors such as defensivity and anxiety -are discernable. We also present parallel results of (3) suppression and inhibition in memory and language processing. A similar observation in these various results is that inhibition reveals itself by spilling over to associated elements which were not its original targets. Finally, we propose a speculative model on the physiology of repression. First, we present a series of arguments indicating a conceptual closeness between the 'indications of reality' in the Freudian model and the efference copies of the sensorimotor models. Moreover, a number of other parallels between the psychodynamic and the sensorimotor approach have been uncovered in recent neurosciences, chief among which is the constitutive link between representation and action: thinking is only possible as a motor activity and this thinking is not a priori conscious. Afferent stimuli probe for a multiplicity of associated action plans: directed action, then, is only possible by selecting one alternative through inhibition of the others. This inhibition might function through the anticipative attenuation brought about by the efference copies. The efference copy-induced somatosensory activations linked to motor control are thought to induce mental imagery in response to incomplete action execution. This, then, would be especially the case for some of these action alternatives, which are easily susceptible of popping up due to their emotional importance. In order to act appropriately, these frequent candidates require a more vigorous inhibition, which would then be particularly prone to induce (unconscious) mental imagery as well as to spill over to associated representations and induce substitutive behaviours, which, together, would constitute 'the return of the repressed'.
