Geografia dos movimentos socioterritoriais no Brasil de 2000 à 2012

The struggle for land is not a recent theme in Brazilian history. Since colonization, people have fought and resisted against oppression and injustice in the countryside, as can be evidenced by the highwaymen, peasant leagues and the war of Canudos. More recently, the struggle for land and agrarian reform can be evidenced by the struggles of the MST, CONTAG, CPT and other movements. For these movements, denominated as socioterritorial movements, land/territory is an essential condition for their existence and for the maintenance of their territoriality. The present paper examines the geography of socioterritorial moviments: the construction of the concept of socioterritorial movements and their forms of action and scales of actuation in the period 2000 to 2012, focusing on the movements that have been most active. These movements are studied through as analysis of data of the Land Struggle Data Base (Banco de Dados da Luta pela Terra –DATALUTA), print and digital media reports and a bibliographic survey of the literature. The action of socioterritorial movements can be studied through the forms of land occupations and demonstrations in the countryside which are the principal means of the struggle against large landholders, agribusiness and the State. These actions question the model of development which privileges agribusiness and, as such, are viewed by some as a hindrance to the development of the country. Over the years, the number of socioterritorial moviments, and their actions have oscillated due to a series of factors, such as repression (criminalization of members and violence against them), policies adopted by Brazilian governments and the contradictions inherent in very process of the spacialization of the struggle for land. These actions can be analyzed according to the scale of the struggle of the movements – municipal, micro-regional, state, macro-regional, and national

Amorphous ZrF4-a molecular dynamics study

Using an effective two-body interaction potential, a molecular dynamics study of the structural properties of amorphous ZrF4 phase is presented. The effective pair potential includes steric repulsion, Coulomb interaction due to charge transfer, and charge-dipole interaction due to the large electronic polarizability of anions. The results for structural correlations, such as pair distribution functions, coordination numbers, and bond angle distributions are presented. Excellent agreement is obtained by comparing experimental X-ray diffraction and the simulated static X-ray structure factor. © 1993.

Benzene solubility in ionic liquids: working toward an understanding of liquid clathrate formation

The solubility of benzene in 15 imidazolium, pyrrolidinium, pyridinium, and piperidinium ionic liquids has been determined; the resulting, benzene-saturated ionic liquid solutions, also known as liquid clathrates, were examined with (1) H and (19) F nuclear magnetic resonance spectroscopy to try and understand the molecular interactions that control liquid clathrate formation. The results suggest that benzene interacts primarily with the cation of the ionic liquid, and that liquid clathrate formation (and benzene solubility) is controlled by the strength of the cation-anion interactions, that is, the stronger the cation-anion interaction, the lower the benzene solubility. Other factors that were determined to be important in the final amount of benzene in any given liquid clathrate phase included attractive interactions between the anion and benzene (when significant), and larger steric or free volume demands of the ions, both of which lead to greater benzene solubility.

A quantitative analysis of the polarization reversal in the 73 mol % vinylidene fluoride-27 mol % trifluorethylene copolymer

We show that a time-dependent, effective-medium approximation essentially explains the time behavior of the polarization reversals obtained in doped copolymers of vinylidene fluoride and trifluorethylene at 60°C by Ieda, Fukada, and Wada [J. Appl. Phys. 64, 2026 (1988)], who attributed the observed effects to charge accumulation at the boundaries of the permanently polarized crystallites. Moreover, the results seem to indicate that some hindrance (perhaps of mechanical origin) opposes the action of the switching electric field.
