Las imágenes fotográficas de América Latina en O Cruzeiro Internacional

Assuming that photographic images involve a process of aestheticization of events that is related to the construction of social identities, organizing the sensible and promoting standards and norms of behavior, the aim of this article is to study how the identity of Latin America was represented in the magazine O Cruzeiro Internacional from a study of photo reports published in this journal. In this article, we will explore the editorial project of this publication and we will study how this project was materialized in specific photo reports. These photo reports engendered a number of stereotypes about Latin America, linked to the American way of life and its values of development and consumption.

Deformación del área de corte de las limas endodónticas sometidas a diferentes métodos de precurvatura

Objetive: Evaluate the deformations caused in the cutting edges in the K-file #25 (LK), subjected to pre-beinding of the apcial third using the following methods: finder-bending, cotton-pliers bendin and Flexobend, observed under scanning electron microscopy (SEM). Material and methods: Forty-eight LK#25 were divides into 4 groups (n=12); G1, control; G2, finger-bending; G3, cotton-plier bending, G4, Flexobend. The curvature was standardized in the apical segment of the file at 2 mm of D!. Was constructed a model of acrylic resin that correspond to a canal of 20º of curvature. The files were examined under SEM (260X). Data were analyzed using Fisher´s statistical test with a significance level of 5%. Results: The images showed no alterations in the LK, similar to G3, with no statistical difference. G3 and G4 were statistically different form the other groups (p<0.05). Conclusions: the finger-bending method to curve apical third of LK #25 did not alter the cutting edges, the cotton-pliers bending and Flexobend did alter the cutting edges of the files (AU)

A estética da imagem na TV digital

This text reflects on the techniques and the process of image production and its artistic composition to digital television in high defini- tion, whereas the 4:3 and 16:9 formats will exist until shutdown of the analog signal. Within this period, consumers of television programming that have analog receivers will continue to see the images in 4:3 format. That fact determines that the productions in high definition, while capturing images with larger viewing area and have high contrast ratio (>1000:1) must be main- tain the elements of visual storytelling within the smallest area and with the contrast ratio of the analog tv (30:1), at the risk of distorting visually the messages produced by the directors.

Análise do conflito do uso e ocupação da terra em área de preservação permanente através do SIG

This study aimed to map the classes of use and occupation and their conflicts in Areas of Permanent Preservation (APPs) in the basin of Ribeirão São Pedro - Botucatu (SP) with the use of remote sensing techniques - image obtained by satellite 2011 - and the use of GIS. For this, we used the GIS techniques, and the integration of information held in the Geographic Information System (GIS) - IDRISI, coupled with the use of digital maps, published by the Brazilian Institute of Geography and Statistics - IBGE, scale 1: 50,000 and satellite images LANDSAT - 5 (2011) sensor TM (Thematic Mapper) with spatial resolution of 30 x 30 meters, provided by the National Institute for Space Research (INPE) .The Geographic Information System (GIS) was used IDRISI Selva and software, CartaLinx. This work had as legal support environmental legislation, specifically, the Federal Law 12.651 / 12. Thus, the study of the watershed becomes an important tool to understand its dynamics in relation to the use and occupation of their area and to characterize their environmental problems and taking as legal counsel to the preservation and conservation of the land to support environmental legislation.
