O desafio da coordenação e seus impactos sobre a competitividade de cadeias e sistemas agroindustriais

Este artigo pretende apresentar alguns dos conceitos de coordenação de sistemas agroindustriais (SAGs) e de competitividade entre cadeias, mais especificamente as cadeias de carnes (bovinos, suínos e aves). em seguida, são analisados alguns exemplos recentes de diferentes formas de coordenação de SAGs e como elas afetam a competitividade entre as cadeias.

Estruturas, arquitetura e evolucao do Complexo Granitoide Itaqui (SP)

The Itaqui Granitoid Complex is a drop shaped WNW-ESE trending intrusion with its head' at west. Its contacts with the low-grade metamorphic rocks of the Sao Roque Group are intrusive at west, northwest, north and northeast, and tectonic at south and northeast. The complex is built up by four main intrusive phases which characterize a rising and unroofing process. Petrographically the Itaqui granite comprises five distinct magmatic associations in nine igneous units. -from English summary

Arquitetura da parede vascular de segmentos torácico e abdominais da aorta de macaco prego (Cebus apella)

The intimal layer of the thoracic and abdominal aortic segments of Cebus apella monkey presented an evident inner elastic lamina. The medial layer of the thoracic aorta segment showed a basic lamellar elastic pattern having a medium average of 23.12 lamellae per analyzed cut sections, which appeared disposed circular and oblique relatively to the aortic lumen. The aortic adventitial layer, at this level, was formed mainly by collagen fibers, irregularly disposed between elastic fibers and smooth muscle cells. The aortic abdominal portion, in this monkey, at the suprarenal level presented a medium number of 19.12 elastic lamellae which showed a relatively disorganized and broken up pattern. At the infrarenal level the aortic medium layer showed a medium average of 11.75 elastic lamellae and next to the emission of the internal iliac arteries it was found only a middle average of 8.37 elastic lamellae intermingled with smooth muscle cells and collagen fibers whose concentration seemed to be increased next to the adventitial layer. The external elastic lamina was only present in the more distal aortic segment near to the emission of the internal iliac arteries.

O projeto para o pavilhão brasileiro na expo' 92 em sevilha e a chamada arquitetura paulista

This article discusses the controversy surrounding the winning project of the competition organized by the Brazilian Ministry of Foreign Affairs for the Brazilian pavilion at the Expo'92 in Seville, Spain; the views of architecture critics made at the time of the results, and, their implications for Brazilian architecture. At the beginning of the 90s, this competition was a kind of confrontation of ideas, between the architects who were in favour of a renewal of architecture and those who defended the resumption of national architectural traditions, buildings with large spans, constructed in reinforced concrete. These architects were the heirs of the so called Paulista architecture, which was characterised by the work undertaken from the 60's by important architects such as Vilanova Artigas and Paulo Mendes da Rocha. The modern references adopted by the winning project, from the architects Angelo Bucci, Alvaro Puntoni and José Oswaldo Vilela, sparked controversies because of the difficulty of resuming the teachings of the old modern masters when faced with new times. These controversies were related to the end of the military dictatorship in Brazil and the process of opening markets, and by the relevance of a re-evaluation of the so-called Paulista architecture.

Fault current limiter using transformer and modular device of YBCO coated conductor

In this work, we report on the evaluation of a superconducting fault current limiter (SFCL). It is consisted of a modular superconducting device combined with a short-circuited transformer with a primary copper winding connected in series to the power line and the secondary side short-circuited by the superconducting device. The basic idea is adding a magnetic component to contribute to the current limitation by the impedance reflected to the line after transition of the superconducting device. The evaluation tests were performed with a prospective current up to 2 kA, with the short-circuited transformer of 2.5 kVA, 220 V/660 V connected to a test facility of 100 kVA power capacity. The resistive SFCL using a modular superconducting device was tested without degradation for a prospective fault current of 1.8 kA, achieving the limiting factor 2.78; the voltage achieved 282 V corresponding to an electric field of 11 V/m. The test performed with the combined SFCL (xsuperconducting device + transformer) using series and toroidal transformers showed current limiting factor of 3.1 and 2 times, respectively. The test results of the combined SFCL with short-circuited transformer showed undesirable influence of the transformer impedance, resulting in reduction of the fault current level. © 2002-2011 IEEE.
