Im Werk Portugal Hoje. O Medo de Existir - Portugal heute. Die Angst des Existierens, zitiert F. Gil ein Lissabonner Graffitti. Não há drama, tudo é intriga." [[Kein Drama. Es ist alles Intrige], um daraus ein Motto für seine Analyse der gegenwãrtigen portugiesischen Gesellschaft zu entnechmen. Unfãhig, ihre herkõmmlichen Formen von Solidaritãt und gegenseitiger Hilfe wieder in Kraft zu stzen, sei die portugiesische Gesellschaft im chaotischen Ozean der Konkurrenz, der Arbeitslosigkeit und des Ausschlusses so tief gesunken, dass sie sich wegen der ihr gestellten Herausforderungen bedroht fühle. Der portugiesischen Gesellschaft würde es nicht gelingen, die Angst zu überwinden, die sie direkt aus der ehemaligen autoritãren und diktatorialen Gesellschaft als Erbe bekommen hatte, deren strukturelle Hauptstütze die Angst war - wie auch ein System, dessen Hauptziel es war, die Fõrderung der Kreativitãt , der schõpferischen und unternehmerischen Krãfte des sozialen, wirtschaftlichen Lebens zu unterdrücken; unter der Diktatur Salazars lebte man schon unter dem Einfluss der Gehorsamkeit, der Korruption, des Nicht-Teilnehmens, des Nicht-Einwerbens, des Nicht-Ereignens.

A recepção da ideia de Babilónia entre os assírios: a construção de um mito

O tema apresentado nesta Dissertação incide sobre as relações entre a Assíria e a Babilónia durante o período neo-assírio, ou seja, entre os séculos X e VII a.C., tendo como principal objectivo compreender qual a percepção que a Babilónia teve entre os assírios. Para tal, analisaremos os diferentes métodos utilizados pela Assíria para governar o seu vizinho meridional e o modo como os reis assírios se relacionavam com os babilónios e os seus deuses. Pretende-se compreender como os babilónios se destacavam entre todos os outros povos com que os assírios se relacionavam e de que modo esse relacionamento afectou a própria Assíria.

Development of a fundus camera for analysis of photoreceptor directionality in the healthy retina

The Stiles-Crawford effect (SCE) is the well-known phenomenon in which the brightness of light perceived by the human eye depends upon its entrance point in the pupil. This physiological characteristic is due to the directional sensitivity of the cone photoreceptors in the retina and it displays an approximately Gaussian dependency which is altered in a number of pathologies. Retinal imaging, a widely spread clinical practice, may be used to evaluate the SCE and thus serve as diagnostic tool. Nonetheless, its use for such a purpose is still underdeveloped and far from the clinical reality. In this project a fundus camera was built and used to assess the cone photoreceptor directionality by reflective imaging of the retina in healthy individuals. The physical and physiological implications of its development are addressed in detail in the text: the optical properties of the human eye, illumination issues, acquiring a retinal image formed by the eye, among others. A full description of the developmental process that led to the final measuring method and results is also given. The developed setup was successfully used to obtain high quality images of the eye fundus and in particular the parafoveal cone photoreceptors. The SCE was successfully observed and characterized. Even though considerable improvements could be done to the measurement method, the project showed the feasibility of using retinal imaging to evaluate the SCE thus motivating its usage in a clinical environment.

Effects of Rosmarinus officinalis essential oil on germ tube formation by Candida albicans isolated from denture wearers

Introduction The aim of this study was to investigate the effects of Rosmarinus officinalis essential oil on germ tube formation by Candida albicans isolated from denture wearers. Methods Ten C. albicans isolates recovered from denture wearers were tested using 10% fetal bovine serum with or without 4% R. officinalis essential oil. Results The essential oil from R. officinalis completely inhibited germ tube formation in the investigated C. albicans isolates. Conclusions The results demonstrate that the essential oil of R. officinalis modulates C. albicans pathogenicity through its primary virulence factor (i.e., germ tube formation was suppressed).
