Santo de casa faz milagre: Luíz da Câmara Cascudo, o padroeiro literário da cidade de Natal

Assuming that the subject is a draft work in permanent invention, the biographical texts, memories written by Luís da Câmara Cascudo, between 1967 and 1969 were read as part of a discursive strategy created by the potiguar memorialist regarding the construction of a self-image profoundly connected to the space of his house, which decisively collaborated so that the province teacher and researcher after announcing his official retirement in 1968 was revered in the city where he had been born, grown up and lived throughout his whole life and considered as the prophet of his own country (or rather, as the literary patron of Natal). Our work begins with some reading about the manner as the potiguar memorialist selected, ordered and spatialized his childhood memories. In the following chapter, we problematized the meanings assigned by Câmara Cascudo to his house in Tirol - where the young prince Cascudinho (little Cascudo) used to live - transformed into the neighborhood principality. It finishes with memories from the retired old man with the purpose of making us think about the sacredness process master Cascudo s house has gone through. The space where he had lived for almost forty years of his life and produced a great part of his works, was elected as a monument in his memory, as his own incarnation, as guarantee of his eternity and perenniality, as a sanctuary and place of worship and have been kept by the actions that, still nowadays, institutionalize it as his sacred space

Estudo da hidrodinâmica de um novo separador líquido-líquido: aplicação ao sistema óleo-bruto/água produzida

This work aims to use a different hydrodynamic condition applied to a new design of mixer-settler on treating wastewater produced by petroleum industry, called MDIF (Misturador-Decantador à Inversão de Fases/ Mixer-Settler based on Phase Inversion MSPI). The use of this different hydrodynamic behaviour is possible due to vertical disposition of the device and the principle of Phase Inversion that controls the MDIF, providing the generation (creation) of a cascade of drops, into an organic layer, that works as micro-decanters, thus making possible the formation of a bed of non-coalesced drops, called Bed Formation . The use of this new hydrodynamics condition allows to increase the residence time of the oil carrier drops, into an organic layer, and the device can treat a greater volume of wastewater. In view of to get this condition it is necessary to operate at high throughput (58,6 m3.m-2.h-1). By results, the condition of Bed Formation is the best one to be used when MSPI operates with throughput up to 58,6 m3.m-2.h-1. The results using the condition of Bed Formation show that increasing the height of the bed of non-coalesced drops and/or decreasing the volumetric ratio (O/A) an increase of the separation efficiency is detected

O teatro de Deus: a construção do espaço sagrado de juazeiro a partir de narrativas femininas (Ceará, 1889-1898)

In this work, we discuss the construction of Juazeiro in the state of Ceará -, as a sacred space from the analysis of the testimonies of nine religious women called beatas in an Episcopal process in the late nineteenth century. This process was initiated in 1891 to investigate the occurrence of an Eucharistic miracle with beata Maria Magdalena do Espírito Santo de Araújo. We show that the punitive strategies of the Diocese eventually caused a reordering of pilgrimages to Juazeiro which until 1894 worshipped the Precious Blood and that after the condemnation of the phenomena by the Holy See are rearranged around the figure of Father Cicero Romão Batista, under the pretext of worshipping the priest himself and also Nossa Senhora das Dores, currently the patron saint of the city of Juazeiro do Norte.

Estudo in silico das interações da protease NS3-NS2B de DENV-2 com o inibidor peptídico Bz-nKRR-H com finalidades terapêuticas

Dengue virus is an important patogen that causes Dengue desease in all world, and belongs to Flavivirus gender. The virus consists of enveloped RNA with a single strand positive sense, 11Kb genome. The RNA is translated into a polyprotein precursor, wich is cleaved into 3 structural proteins (C, prM e E) and 7 non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B e NS5). The NS3 is a multifunctional protein, that besides to promote the polyprotein precursor cleavage, also have NTPase, helicase and RTPase activity. The NS3 needs a hydrophilic segment of 40 residues from the transmembrane NS2B protein (who acts like cofator) to realize this functions. Actually, there's no vacines available on the market, and the treatment are just symptomatic. The tetrapeptide inhibitor Bz-Nle-Lys-Arg-Arg-H (Ki de 5,8-7,0 M) was showed as a potent inhibitor μ for NS3prot in Dengue virus. That is a inteligent alternative to treat the dengue desease. The present work aimed analyse the interactions of the ligand bounded to the activity site to provid a clear and depth vision of that interaction. For this purpouse, it was conducted an in silico study, by using quantum mechanical calculations based on Density Functional Theory (DFT), with Generalized Gradient approximation (GGA) to describe the effects of exchange and correlation. The interaction energy of each amino acid belonging to the binding site to the ligand was calculated the using the method of molecular fragmentation with conjugated caps (MFCC). Besides energy, we calculated the distances, types of molecular interactions and atomic groups involved. The theoretical models used were satisfactory and show a more accurate description when the dielectric constant = 20 ε and 80 was used. The results demonstrate that the interaction energy of the system reached convergence at 13.5 A. Within a radius of 13,5A the most important residues were identified. Met49, Met84 and Asp81 perform interactions of hydrogen with the ligant. The Asp79 and Asp75 residues present high energy of attraction. Arg54, Arg85 and Lys 131 perform hydrogen interactions with the ligand, however, appear in BIRD graph having high repulsion energy with the inhibitor. The data also emphasizes the importance of residue Tyr161 and the involvement of the catalytic triad composed by Asp75, His51 and Ser135
