An Analysis of the Spectral Energetics for a Planet Experiencing Rapid Greenhouse Gas Emissions  [PDF]
André Ferreira Aranha, José Augusto P. Veiga
Atmospheric and Climate Sciences (ACS) , 2017, DOI: 10.4236/acs.2017.71009
Abstract: So far, energetics studies related to climate change have focused on the disturbed and undisturbed kinetic and potential energies, as well as their transformations, without dealing with the energetics involved in the phenomena of different spatial scales. Thus, the present work reports the first analysis of the spectral energetics for a condition of climate change, followed by the high-range emission scenario, RCP8.5, which originated from the new Max Planck Institute Earth System Model (MPI-ESM). The results showed that both types of generation (Go and Gn), baroclinic processes (Co and Cn), kinetic energies (Ko and Kn) and the barotropic process, Mn, significantly increase in the condition of a warming climate. Moreover, the results still reveal that in the most components of the energetics, is the planetary scale waves that are the most impacted under a climate change scenario. These results highlight that global warming can have different impacts on particular types of motions.

ABCD. Arquivos Brasileiros de Cirurgia Digestiva (S?o Paulo) , 2012,
Abstract: RACIONAL: A cirurgia minimamente invasiva ganhou rapidamente papel fundamental no tratamento da doen a do refluxo gastroesofágico. Entretanto, o melhor método para as grandes hérnias paraesofágicas (tipos III e IV) ainda está em discuss o. O uso de próteses para refor o da hiatoplastia tem sido proposto por diversos autores, no intuito de diminuir as altas taxas de recidivas encontradas nesses pacientes. Riscos de estenose e eros o da prótese s o as complica es mais preocupantes quando se pensa em aplicar uma prótese no hiato esofágico. OBJETIVO: Demonstrar a técnica cirúrgica e resultados do uso de um modelo de tela idealizado no servi o dos autores para refor ar a hiatoplastia em grandes hérnias de hiato. MéTODOS: Uma prótese de polipropileno foi aplicada para refor o da hiatoplastia em pacientes com grandes hérnias de hiato (Tipos II a IV de Hill). A prótese era cortada em forma de U, com sutura de cateter de silicone na borda c ncava que ficaria em contato com o es fago. Após sua fixa o sobre a hiatoplastia, toda prótese era recoberta por gordura do omento maior, impedindo contato com o fundo gástrico ou fundoplicatura. RESULTADOS: De 1999 a 2012, esta técnica foi utilizada em 70 pacientes. Eram 52 do sexo feminino e 18 do sexo masculino, com idades variando de 32 a 83 anos (média de 63 anos). Em 48 (68,6%) pacientes, tratava-se de hérnias primárias e em 22 (31,4%) era recidivada após opera o antirrefluxo. O único óbito ocorreu por sepse (1,4%) no 22o dia pós-operatório em caso com lacera o da sutura da fundoplicatura causando fístula gastropleural. N o houve rela o direta com o uso da prótese. Seguimento de seis meses ou mais foi obtido em 60 pacientes (85,7%), variando de seis a 146 meses (média de 49 meses). Todos os pacientes foram submetidos à entrevista clínica e pelo menos uma endoscopia e/ou radiografia contrastada no período de acompanhamento. Durante o seguimento, n o foram observadas complica es (estenose ou eros o) relacionadas com a prótese. CONCLUS O: O uso do modelo de prótese de polipropileno descrito é seguro, desde que observados os aspectos técnicos de sua implanta o. BACKGROUND: The minimally invasive surgery has gained rapidly important role in the treatment of gastroesophageal reflux disease. However, the best method to treat large paraesophageal hernias (type III and IV) is still under discussion. The use of prosthetics for enhancing the crural repair has been proposed by several authors in order to reduce the high relapse rates found in these patients. AIM: To demonstrate the technique and surgical results in using an i

Delgado, Andréa Ferreira;
Horizontes Antropológicos , 2005, DOI: 10.1590/S0104-71832005000100007
Abstract: in this article, i investigate the institution of goiás as a historical and touristic town, interweaving discoursives series that gives visibility and meanings to the town by working the relations of urban space, time and the history: the delimitation of the town as a cultural values through the incorporation of the national patrimony discourse; the invention of local traditions promoted by organiza??o vilaboense de artes e tradi??es; the production of the town "patrimony of humanity" in the dossier of goiás and the writing of cora coralina's memory that takes the form of the past inscribed in the texture of the town material.
MACHADO DE ASSIS E A LITERATURA BRASILEIRA DO OITOCENTOS: UM PROJETO DE LITERATURA NACIONAL
Ricardo André Ferreira Martins
Revista de História Regional , 2007,
Abstract: Our aim, in this work, were to reach a different vision about ideologics attitudes of Machado de Assis when in beginning of your literary career, as articulist, and your opinions about the national literature. We intend to demonstrate how, even in Machado, there is the manifestation of one civilizing preoccupation that give the tonus of our literature during all Brazilian nineteenth century. To reach this aim, we utilize one only article, in which are more evidents the symptoms of this attitude of esthetizing and moralizing character. Nosso objetivo, no presente trabalho, foi possibilitar uma vis o diferenciada das posturas ideológicas de Machado de Assis quando no come o de sua carreira literária, como articulista, e suas opini es sobre a literatura nacional. Pretende-se demonstrar como, mesmo em Machado, há a manifesta o de uma preocupa o civilizatória que dá o tom de nossa literatura durante todo o período do oitocentos brasileiro. Para atingirmos este fito, utilizamos de um artigo apenas, no qual estivessem mais evidentes os sintomas desta atitude de fundo estetizante e moralizante.
To tell or not to tell. Caio Fernando Abreu: subject and not-said of the speech of the AIDS in the novel Onde andará Dulce Veiga?
Carlos André Ferreira
Via Litterae , 2011,
Abstract: In this article we discuss the novel Onde andará Dulce Veiga? (1990), by Caio Fernando Abreu, focusing on the issue of AIDS, the not-said of its speech and the subject. Considering the historical and social context around AIDS in the 1980s, the period that goes the plot of the novel, this analysis is guided in questioning how the disease is built throughout the book. In Caio Fernando Abreu’s Onde andará Dulce Veiga? we are faced with an unnamed narrator who goes in search of Dulce Veiga, a singer who made some success in an age previous to the moment when the narrator tells his story and who disappeared mysteriously. The period of success and the very figure of the singer Dulce Veiga are identified with the Radio Age and its glamor. Amid the search for the singer the narrator becomes involved in a plot in which AIDS is a means in the form of the unsaid. The disease presents itself, in a roundabout way, amid the destruction perceptible to the senses of space-time elements present in the narrative and through the effects of decay that the narrative suggests.
SER, ANGúSTIA E POESIA: UMA LEITURA HEIDEGGERIANA DE NAURO MACHADO
Ricardo André Ferreira Martins
Signótica , 2012, DOI: 10.5216/sig.v24i1.17094
Abstract: O objetivo deste artigo é tra ar um paralelo interpretativo entre a filosofia heideggeriana, sobretudo em seus conceitos mais conhecidos, e a poesia de Nauro Machado. Analisa-se, comparativamente, os principais conceitos, como estar-no-mundo (facticidade), ser-no-mundo (existencialidade) e vir-a-ser (angústia). Demonstra-se como cada um destes conceitos s o extremamente elucidativos em uma abordagem existencialista da poesia de Nauro Machado, com ênfase sobretudo no conceito de angústia, tema central da lírica do poeta.
Abordagens de utiliza o de arquiteturas middleware em aplica es robóticas embarcadas
Gustavo André Nunes Ferreira
Exacta , 2006,
Abstract: Embedded systems, specially the robotic ones, present a multiplicity of devices in its structure which often based on different technologies of hardware and software and connected by different network technologies and protocols , results in a considerably heterogeneous and well distributed architecture. In order to improve the comprehension over the complexity inherent to the distributed systems the new concept of middleware emerged as a software integration layer. The main objective of this article is to expose, by means of a general view, the use of middleware architectures in embedded robotic applications, particularly that with devices of scarce availability of resources (memory, processing capacity and communication), such as microcontrollers and smart sensors, and to analyze different approaches for a convenient use of these architectures.
