Trabalhadores hóspedes: herders, borregueros ou peões nas montanhas rochosas dos Estados Unidos e Canadá

In the contemporary world and in the globalized farm labor market, employ temporary immigrants workforce become current in economic developed countries. With governmental support, nations as United States and Canada incite and lawful the foreign entrance for occupy jobs and functions that are not fulfilling by native born, consolidating the displacement of a cheap labor force that stays legally for a certain season in these countries. This article brings up primal subjects about a small and hidden group among farm immigrants, the herders, sheepherders and goat herders in northAmerica Rocky Mountains loneliness. Further to provide an initial theoretical instrumental for the reflections about these workers, we intend to localize them within migration theme and the conflict between capital and labor in these days, in its neoliberal context and struggle forms. For such, we used reflections about labor and migration, also different kind of documents about herders in both countries.

A questão da colonização no Brasil: historiografia e documentos

In this article we draw attention to the fact that the documentation relating to the decision to colonize Brazil, as well as the early stages of colonization, comprising two interpretations about the reasons to occupy, populate and organize the production on American soil. The Brazilian historiography joined the explanation of that pressure from European nations led to the Portuguese crown decided on an occupation more effectively. But without ignoring this reason, the documentation allows to take into account their own historical circumstances created by the development of trade. These are essential conditions for the emergence and effectiveness of the proposal to colonize Brazil. Thus, when considering only the pressure of European nations the Brazilian historiography remained on the surface of events. It’s necessary to take into account the documentation on what it allows to grasp the colonial process as a historical phenomenon and not just as an act of will.

Obtenção e caracterização óptica e elétrica de 'La''Ta'O IND.4' e LiTaO Ind.3 puros e dopados com Eu POT.3+

Eletronicalceramics are used in many applications such as: multilayer capacitor, transducer, pyroelectric sensors and electrooptic devices. In recent years there has been a growing demand for eletronicalceramics with better performance and functionality. This demand has accelerated the development of synthesis techniques to produce powders with well-defined particle size, shape and crystallinity. The eletronicalceramics in the form of bulk are determined by their performance characteristics of the powders used and the preparation process. So, physical and chemical properties of powders, such as chemical control of stoichiometry, purity, homogeneity, particle size and shape should be observed when choosing the methods of synthesis. Among the techniques used so far, the polymeric precursor method, also known as Pechini, has been considered ideal for the preparation of nanosized powders. Thus, this research project aims to use the polymeric precursor method to prepare powders of lithium tantalate and lanthanum tantalate, with good chemical stability. In this aspect is proposed to investigate the effects of variation of the concentration of europium about the properties of tantalate because doping with Eu3 + indicates that they may occupy different sites in the crystal structure, as in the case of LiTaO3. Effects of things like occupation sites, stability of phases and formation temperature have been previously investigated by the group, which motivated the formulation of this project. Our proposal aims to introduce the Eu3 + LaTaO4 and LiTaO3 and study the structural and optical properties of the powders obtained by Pechini method, as well as correlate these studies with the electrical properties of the material, mainly the Ironelectricty Hysteresis.
