Sua descrição teórica é feita a partir das noções de paixão encontradas na literatura filosófica até chegar a psicanálise e sua problemática metapsicológica. As diferentes modalidades de passividade são descritas sob a ótica do sadismo e do masoquismo na teoria fteudiana para permitir uma articulação com a hipótese argumentativa de que é a passividade que faz certas coisas acontecerem na melancolia. A peça shakesperiana de Hamlet fornece uma perspectiva heurística, ficcional na qual o personagem principal atrai sobre si uma sorte de fatalidade que isola-o do contato com o outro e torna-o cada vez mais passivo. Trata-se de uma passividade curiosa, atípica, intrigante. Uma passividade que transporta rapidamente o leitor à clínica psicanalítica e interpela diretamente o papel do analista na relação transferencial / Abstract: The doctorate thesis entitled "The issue of passivity in melancholy: the paradigm of Hamlef' deals with some clinical questionings about the action of passivity and its consequent impact on the analytical relationship in a case of melancholy. Its theoretical description begins ITomthe notions of passion found in the philosophicalliterature to arrive to psychoanalysis and its metapsychological problematic. The different modalities of passivity are described ITom the standpoint of sadism and masochism in the Freudian theory to better link them to the argumentative hypothesis tOOtpassivity makes certain things OOppen.The Shakespearean play Harnlet offers a heuristic, fictional perspective in which the main character attracts a kind of fatality that isolates him ITomthe contact to the others and makes him increasingly passive. This is a weird, atypical and amazing passivity, which quickly refers the reader to the psychoanalytical clinic and directly questions the role ofthe analyst in the transferential situation / Mestrado / Farmacologia / Mestre em Farmacologia

The kinetics of drugs photodegradation have traditionally been treated using thermal kinetic analysis methods consisting most commonly in zero and first order kinetics. These treatment strategies were shown to lack specificity and present a number of limitations when applied to photoreactions kinetics. Nevertheless, these methods have widely been used due to a lack of integrated rate-laws for the majority of photoreactions types, in turn, due to the presence of a variable time-dependent factor in most photoreactions rate-laws that prevents their mathematical integration. To address these limitations, a new methodology for the development and validation of semi-empirical integrated rate-laws that faithfully describe photoreactions kinetics and photoreactions simulated cases generated by numerical integration methods (NIMs), is hereby presented. Using this methodology, a new kinetic order was ascribed to photoreactions namely the Φ-order kinetics. Semi-empirical integrated rate-laws were, thus, developed for three photoreaction types namely, unimolecular, AB(1Φ), photoreversible ,AB(2Φ), and consecutive, AB4(4Φ), photoreactions. The proposed models were further tested experimentally on drugs following these photodegradation mechanisms using; nifedipine and nisoldipine for unimolecular photoreactions; montelukast and fluvoxamine for photoreversible reactions; and riboflavin for consecutive photoreactions. The developed models not only accurately described the photoreaction kinetics of these drugs but also allowed the determination of all the kinetic parameters that characterise them. Furthermore, the above studied drugs were shown to act as precise and simple actinometers when analytically treated with the Φ-order kinetic methods, hereby presented. A universal standard method for the precise and worldwide reproducible study of drugs stability and compounds photoreactions, based on monochromatic irradiation and Φ-kinetics data analysis, is also detailed and adopted throughout the thesis. Finally, two new kinetic parameters namely, the pseudo-rate-constant and pseudo-initial velocity have been identified and shown to be more reliable and accurate in the description and universal comparison of photoreactions kinetics.
