Abstract: this article aims to update the discussion on the issue of alimentary (in)security in brazil, from the perspective of two hypotheses to justify the concentration of income and the agrarian concentration. from these two hypotheses, an analysis of major public policies implemented during president lula's two terms, and which regard alimentary security, is carried out: the welfare programs zero hunger and bolsa familia.
Avalia??o da simetria da imagem do ramo da mandíbula em radiografias panoramicas
CARVALHO, Antonio Augusto Ferreira;
Pesquisa Odontológica Brasileira , 2000, DOI: 10.1590/S1517-74912000000300011
Abstract: panoramic radiographic methods provide images which present distortions of bilateral anatomical structures of the face as well as magnification. currently, panoramic radiographs have been used to analyze vertical, horizontal and angular measurements. in an attempt to evaluate the presence of symmetry in the bilateral images of the mandibular rami, both their area and perimeter were obtained from panoramic radiographs of 8- to 10-year old children. the contour of the images of both rami was divided at the gonial angle and at the deeper point of the anterior border and it was transferred to translucent tracing paper and then to a computer through a scanner apparatus. the images were measured using a scan software and the values obtained were analyzed. the results showed that there was symmetry in both area and perimeter measurements, in male and female children.
Avalia o da simetria da imagem do ramo da mandíbula em radiografias panoramicas
CARVALHO Antonio Augusto Ferreira
Pesquisa Odontológica Brasileira , 2000,
Abstract: Os métodos radiográficos panoramicos apresentam amplia o das imagens de estruturas anat micas da face, com varia o de uma regi o para outra. Atualmente, este tipo de técnica tem sido utilizado para mensura es verticais, horizontais e angulares. A área e o perímetro da imagem bilateral do ramo da mandíbula foram medidos em radiografias panoramicas obtidas pelo sistema elipsopantomográfico, de crian as dos dois sexos, com idade cronológica entre 8 e 10 anos. Os desenhos, em papel vegetal, da imagem de cada ramo foram capturados através de "scanner" e as medidas foram feitas em microcomputador com aplicativo específico. Duas formas de separar a imagem do ramo da mandíbula, bilateralmente, foram propostas: no g nio e através de uma tangente à parte mais profunda da borda anterior da imagem do ramo que tocava a base. Os resultados obtidos permitiram evidenciar que houve simetria entre os lados, expressa pelas medidas de área e perímetro das imagens do ramo da mandíbula.

Thermo-Hydrodynamics of Core-Annular Flow of Water, Heavy Oil and Air Using CFX  [PDF]
Antonio José Ferreira Gadelha, Severino Rodrigues de Farias Neto, Ramdayal Swarnakar, Antonio Gilson Barbosa de Lima
Advances in Chemical Engineering and Science (ACES) , 2013, DOI: 10.4236/aces.2013.34A1006
Abstract: The transport of heavy and ultra-viscous oil employing the core-flow technique has been increasing recently, because it provides a greater reduction of the pressure drop during the flow. In this context, the effect of temperature and the presence of gas on the thermo-hydrodynamics of a three-phase water-heavy oil-air flow in a horizontal pipe under the influence of gravity and drag forces, using the commercial software ANSYS CFX?, have been evaluated. The standard κ ? ε turbulence model, the mixture model for heavy oil-water system and the particle model for heavy oil-gas and water-gas systems, were adopted. Results of velocity, volume fraction, pressure and temperature fields of the phases present along the pipe are presented and discussed. It has been found that the presence of the air phase and the variation in the temperature affect the behavior of annular flow and pressure drop.

Abstract: the objective of this paper is to present the "atlas of the sea surface temperature over the atlantic intertropical basin by using data from the noaa-14 satellite (1995-2001)". in the atlas, detailed information about the procedures utilized to retrieve sst from noaa-14/avhrr, over the atlantic ocean in the area encompassed by latitudes 10 n-20 s and longitudes 50 w-20 w, were compiled. also included in the atlas, is the complete set of monthly sst images and monthly historical average in the period between 1995 and 2001.based on these images, short description of the sst patterns over the area mentioned before is made. the atlas includes 2 cd's, one of which containing approximately 1250 images already processed, in jpg format, of the sst fields (daily, monthly and monthly mean), includies the software that enables to make the visualization, animation and some basic statistics over the images. the other cd contains the raw sst data base
Modelo de negócios: constructo real ou metáfora de estratégia?
Joia, Luiz Antonio;Ferreira, Sinval;
Cadernos EBAPE.BR , 2005, DOI: 10.1590/S1679-39512005000400002
Abstract: this article analyzes the discussion about the terms "business model" and "strategy", and aims mainly to verify whether these concepts are similar ones. most of the studies already undertaken consider that business model and strategy are different constructs. hence, the aim of this article is to test this hypothesis using an interpretative method based on hermeneutics. in order to accomplish this objective several definitions of business model are compared with two main strategic approaches, namely the positioning school and the resource-based view school. it is concluded that business model and strategy are not entirely different constructs, i.e. there is some overlapping and similarity level between them. furthermore, it is verified that business model acts as a dynamic and systemic tool integrating different strategic approaches and enabling different strategic concepts to be intertwined into a single definition, which increases the potential of these schools to explain and guide the actual strategic process within the organizations.
