Este artigo apresenta uma discussão sobre a organização da força de trabalho indígena livre na Amazônia colônia do século XVII a meados do século XVIII. O texto argumenta que, para além do rígido controle exercido pelas ordens religiosas sobre a população indígena livre estabelecida nas aldeias, não só a coroa vislumbrou alternativas quanto ao uso de trabalhadores indígenas, mas também os moradores se aproveitaram dessas alternativas para ter acesso aos trabalhadores indígenas, principalmente em momentos críticos de carência de mão-de-obra. Por outro lado, trata-se de compreender como a ação dos próprios grupos indígenas influenciou a política e legislação indigenistas implementadas pela Coroa para a região.

O presente artigo trata da caracterização da composição mineralógica de azulejos antigos pertencentes aos séculos XVI, XVII e XIX, coletados em Salvador e Belém, visando à identificação da sua provável matéria-prima e a possível temperatura de queima. Quartzo foi identificado em todas as amostras. As demais fases cristalinas encontradas foram: mullita, cristobalita, calcita, anortita, hematita, gehlenita, diopsídio e wollastonita. Foi possível dividir as amostras em três grupos, em função da possível matéria-prima e temperatura de queima: grupo 1 - caulinita e quartzo, T entre 1200º e 1728º C; grupo 2 - quartzo, caulinita, calcita e/ou dolomita e óxido ou hidróxido de ferro, T entre 900º e 1200ºC; grupo 3 - quartzo, argilominerais (provavelmente caulinita), calcita e/ou dolomita e hidróxido ou óxido de ferro, T entre 1200º e 1565º C.

This report of the BOOST2012 workshop presents the results of four working groups that studied key aspects of jet substructure. We discuss the potential of first-principle QCD calculations to yield a precise description of the substructure of jets and study the accuracy of state-of-the-art Monte Carlo tools. Limitations of the experiments' ability to resolve substructure are evaluated, with a focus on the impact of additional (pile-up) proton proton collisions on jet substructure performance in future LHC operating scenarios. A final section summarizes the lessons learnt from jet substructure analyses in searches for new physics in the production of boosted top quarks.

In this article, we analyze the works of Pero de Magalhães Gândavo in what we name colonial writings. They are texts written between the late 16 th century and the early 17th century. Gândavo’s intention, as with the other colonial writers, is to defend the interests of the settlers. With that, we counter historiography in general and Brazilian historiography in particular, which sees them as authors identified with metropolitan interests.

Since the beginning of time man has used body ornaments, often-simple element of decoration, passing by the object ritualistic and religious icon, also as a symbol to the demonstration of status and power. Many of these objects have survived to today, but the vast majority is lost in time or was dismantled to reuse the material in new jewelry. The history of jewelry uses the pieces that have survived intact, documents and images of those jewels. This work uses of Visual Arts, more specifically the portrait art of, to analyze the mystical amulets of child`s protection jewel in works of painters Juan Pantoja dela Cruz and Diego Velásquez.

Most studies on measures of transpiration of plants, especially woody fruit, relies on methods of heat supply in the trunk. This study aimed to calibrate the Thermal Dissipation Probe Method (TDP) to estimate the transpiration, study the effects of natural thermal gradients and determine the relation between outside diameter and area of xylem in 'Valencia' orange young plants. TDP were installed in 40 orange plants of 15 months old, planted in boxes of 500 L, in a greenhouse. It was tested the correction of the natural thermal differences (DTN) for the estimation based on two unheated probes. The area of the conductive section was related to the outside diameter of the stem by means of polynomial regression. The equation for estimation of sap flow was calibrated having as standard lysimeter measures of a representative plant. The angular coefficient of the equation for estimating sap flow was adjusted by minimizing the absolute deviation between the sap flow and daily transpiration measured by lysimeter. Based on these results, it was concluded that the method of TDP, adjusting the original calibration and correction of the DTN, was effective in transpiration assessment.
