Camu-camu (Myrciaria dubia H.B.K. (McVaugh)) is a native Amazon fruit, recognized worldwide as one of the main natural sources of ascorbic acid. Due to its great acidity, this fruit is generally consumed after processing into juice or as ingredient in food preparations. As a co-product of the camu-camu processing, a significant amount of agroindustrial residue is generated. Despite the studies showing the bioactive value and biological potential of the fruit, few studies have approached the possible processing techniques, transformation and preservation of camu-camu fruits and its agroindustrial pomace. Therefore, the present work has the objective of evaluating two different drying processes applied to camu-camu pomace (peel and seeds with residual pulp), freeze drying and hot air drying, in order to obtain a functional fruit product. This thesis was divided into three stages: the first one shows the studies related to the freeze drying and hot air drying, where we demonstrated the impact of the selected drying techniques on the bioactive components of camu-camu, taking the fresh pomace as the control group. Among the investigated conditions, the groups obtained at 50ºC and 4 m/s (SC50) and 80ºC and 6 m/s (SC80) were selected as for further studies, based on their ascorbic acid final content and Folin-Ciocalteau reducing capacity. In addition to SC50 and SC80, the fresh pomace (RF) and freeze dried (RL) samples were also evaluated in these further stages of the research. Overall, the results show higher bioactive concentration in the RF samples, followed by RL, SC50 and SC80. On the second step of the research, the antioxidant, antimicrobial and antienzymatic activities were evaluated and the same tendency was observed. It was also reported, for the first time in the literature, the presence of syringic acid in dried camu-camu pomace. In the third and final stage of the research, it was investigated the effect of dried camu-camu on aging and neuroprotective disorders, using the in vivo model C.elegans. It was observed that camu-camu extracts were able to modulate important signaling genes relevant to thermal and oxidative stresses (p < 0.05). The polar acid, polar basic and polar neutral fractions obtained from the low molecular extracts of SC50 were able to extend the lifespan of wild type N2 C. elegans in 20% and 13% (p < 0.001). Results also showed that the paralysis induced by the β1-42 amyloid was significantly (p < 0.0001) retarded in CL4176 worms. Similarly, the camu-camu extracts attenuated the dopaminergic induction associated to Parkinson’s disease. Finally, a global analysis of the data presented here reveal that the camu-camu pomace, a co-product obtained from the industrial processing of a native Brazilian fruit, is a relevant natural source of health relevant compounds. This thesis, shows for the first time, the multifunctionality of camu-camu pomace, a natural resource still underexploited for scientific, commercial and technological purposes.

An appropriate design of a prosthetic rehabilitation should not impute the restoration of occlusal vertical dimension (OVD) to new prostheses, at the risk of the patient does not adapt to a new condition, since a certain amount of time is often necessary for adaptation to a new OVD. This article performed prosthetic rehabilitation with an overlay provisional removable partial denture prior to definitive treatment because the patient showed a considerable decrease in the OVD. Three techniques for OVD determination were used. It is possible to conclude that the use of interim removable partial dentures is of great importance at the beginning of the rehabilitation treatment in order to adapt the patient to a new occlusal condition.

L’elaborato si concentra sull’analisi della geologia e della geomorfologia nell’area in cui è situata la località di Libiano, nel Comune di Novafeltria, in Provincia di Rimini e sull’analisi dell’intervento proposto dalla regione Emilia-Romagna a seguito di un evento franoso verificatosi nel febbraio 2015, che aveva evidenziato l’inefficienza dell’opera in gabbioni precedentemente costruita. Sono inoltre state proposte ed analizzate tre soluzioni alternative alla progettazione dell’opera muraria con funzione di sostegno, in quanto la morfologia e la situazione attuale del terreno suggerivano un possibile scenario di frana attiva o quiescente. Queste configurazioni sono poi state sottoposte a verifica seguendo le direttive presenti nelle Norme Tecniche per le Costruzioni del 2008 ed è risultato che solo una delle tre soddisfa le verifiche a flessione e a taglio. È stata inoltre effettuata tramite un software la verifica di stabilità del versante oggetto di studio, privo di opere di sostegno, che ne ha confermato l’instabilità.

Since the middle 80 s from the 20th century, some musical genres associated to the Brazilian Northeastern region notably the forró, coco de embolada and repente de viola have been gradually incorporated to the musical production of south France linked to the occitanista trend, currently linking many musicians and groups from those regions in both countries. This paper is engaged in reflecting on the particular experience of the groups formed by the Escambiar Association, located on the city of Toulouse, and specially the duet Fabulous Trobadors, whose compositions are mostly made in the coco de embolada form. Watching the motivations and the processes that led to the creation of the groups from this association and it s current operation, this study investigates the transcultural phenomenon, that allow to cross two symbolic universes through rationalizing speeches about music, considering the locality s production in the midst of a political debate that involve questions about cultural identity and tradition
