O Visível e o Invisível – Fotografia de Haruo Ohara
No full textEste ensaio visa debruçar-se sobre a poética fotográfica do agricultor-fotógrafo nipo-londrinense, Haruo Ohara, com intuito de mostra que sua fotografia não é, como se afirma quase sempre e com bastante frequência, uma superfície de superficialidade. Ao contrário, nas mãos de certos fotógrafos, como Haruo Ohara, a imagem fotográfica pode ser capaz de fazer ver o mundo de outra maneira, com um convide a um novo aprendizado do olhar. Um reaprender a ver o mundo
Verificação da aplicabilidade do modelo de perfuração Ohara para determinação da taxa de penetração em tempo real nos poços do pré-sal brasileiro
No full textEste trabalho se destina à verificação da aplicabilidade do modelo de
perfuração Ohara para a determinação da taxa de penetração para poços perfurados
na área do Pré-Sal brasileiro. A revisão bibliográfica realizada teve como principal foco
o estudo no ambiente de fundo de poço dos efeitos de diversos parâmetros
operacionais, como Profundidade, Peso sobre Broca, Velocidade de Rotação da
Coluna, Diâmetro de Broca, Hidráulica de Broca, Peso de Fluido de Perfuração,
Pressão de Poros, entre outros. A partir da determinação dos mecanismos físicos que
relacionam a taxa de penetração com cada um dos parâmetros operacionais,
registrados e acompanhados pelo Sistema de Monitoração de sonda (mud logging),
são então apresentados modelos de perfuração visando o estabelecimento do
tratamento matemático da realidade física do problema.
A revisão de diferentes modelos leva à escolha pelo modelo Ohara, o qual
propõe como abordagem matemática a realização de uma de regressão múltipla dos
parâmetros operacionais visando à previsão da taxa de penetração para litologias e
fases do poço estabelecidas. O procedimento adotado se realiza em função também
de parâmetros adimensionais, sendo estes funções dos parâmetros operacionais, Por
fim, é proposto um estudo de caso onde dados de três poços da área do Pré-Sal foram
analisados e para os quais foram inferidos valores respectivos de taxa de penetração
em três diferentes litologias encontradas pelos três poços, quais sejam: Sal, SAG
(rocha carbonática) e Basalto (embasamento ígneo).
A análise global dos resultados verifica ser factível a aplicabilidade do modelo
estudado para essa área, sendo ressaltada a importância da aquisição de um maior e
melhor número de conjuntos de dados objetivando o aumento da confiabilidade do
model

Um contexto, dois olhares: fotografias de natureza segundo José Juliani e Haruo Ohara
No full textAo longo da década de 1930, a cidade de Londrina esteve em processo de construção material e simbólico. Nesse contexto fronteiriço, os fotógrafos José Juliani e Haruo Ohara representaram a natureza de modos estritamente diferentes, embora pertencessem ao mesmo espaço e tempo: o primeiro alimentando visões de grandiosidade, fertilidade e prosperidade inerentes à região, ressaltando, também, a questão do progresso e da civilização; o segundo, por sua vez, malgrado não prescindisse dos lugares-comuns relacionados à fertilidade, chamava a atenção, ao mesmo tempo, para as dificuldades e reveses dessa natureza pródiga, mas, concomitantemente, hostil
