A ribeira da discórdia: terras, homens e relações de poder na territorialização do Assu colonial (1680-1720)

The internalization process of the Portuguese possession in Northern Captaincies - after the Dutch eviction and the development of activities related to livestock in the backlands (Sertão) – expanded the Portuguese territory in America. This process resulted in the advancement of Portuguese conquest over the region and conflicts involving agents of colonization and indigenous groups who inhabited that space, as well as conflicts of interest of captaincy’s major social groups and the defense policies of the Portuguese territory possession. Among the rivers which run through Rio Grande captaincy’s territory, the Açu was the one that aroused conquerors and colonizers of the back lands interest, making that spatiality an area where interest and power exercises converged and generated discord. This research aims to analyze the territorial process of Assu backlands, from the pioneers, conquerors and colonizers action over the space studied, during the event known as the War of the Barbarians in Assu, conflict that ensured the integration of the area the territory and the wishes of the Portuguese crown. Thus, it will be taken as objects of study social phenomena that characterized Assu’s riverside - at the turn of the 17th to the 18th century, in a cutout that extends from 1680 to 1720 - as an area of conflicts of interest, noticeable for analysis from period documents such as records of land grants concessions, correspondence between colonial and kingdom authorities, documents from the exercise of administration of Portuguese America and legislation.

Síntese e Caracterização de Titanatos de Cobalto e Níquel, dopados com Praseodímio, obtidos a partir da decomposição de Nitrilotriacetatos

In recent years, studies about the physicochemical properties of mixed oxides, call attention of the scientific community, properties like as piezoelectricity, photoluminescence, or applications as catalysts, arise in these compounds, when their chemical compositions are modified, in this context some routes are employed in the synthesis of these materials, among which can be cited these methods: ceramic, combustion, co-precipitation, Pechini or polymeric precursor method, hydrothermal, sol-gel; these routes are divided into traditional routes or chemical routes. In this work were synthesized oxides with variable composition, from the thermal decomposition of titanium, cobalt, nickel and praseodymium nitrilotriacetates. The nitrilotriacetates were characterized by IR Spectroscopy (FTIR), Thermogravimetric (TG/ DTG) and Differential Scanning Calorimetry (DSC), while oxides have been characterized by X-ray diffraction (XRD), Spectrofluorimetry and IR Spectroscopy (FTIR). From FTIR data, it was demonstrated that the displacement of the band corresponding to the carboxylate group (νCOOH) at 1712 cm-1, present in nitrilotriacetic acid (H3NTA), for 1680-1545 cm-1, these stretches are characteristics of coordinated nitrilotriacetates, By thermal analysis (TG/DTG /DSC), it was suggested, that in an oxidizing atmosphere (air) oxides are obtained at lower temperatures than in an inert atmosphere N2(g). By results from X-ray Diffraction (XRD), it was determinated that the oxides are crystalline and the predominant phases obtained are summarized titanate phases rutile and ilmenite. By fluorimetry was observed that the intensity of emission bands are directly proportional to the concentration of ions Ni2+, Co2+ and Pr3+, and IR spectroscopy (FTIR) from oxides, demonstrated the disappearance of characteristic bands by nitrilotriacetates, determining the complete decomposition of the nitrilotriacetates in oxides
