Darcy`s law and the differential equation of motion

This note addresses the relation between the differential equation of motion and Darcy`s law. It is shown that, in different flow conditions, three versions of Darcy`s law can be rigorously derived from the equation of motion.

Transient non-Darcy forced convective heat transfer from a flat plate embedded in a fluid-saturated porous medium

Transient non-Darcy forced convection on a flat plate embedded in a porous medium is investigated using the Forchheimer-extended Darcy law. A sudden uniform pressure gradient is applied along the flat plate, and at the same time, its wall temperature is suddenly raised to a high temperature. Both the momentum and energy equations are solved by retaining the unsteady terms. An exact velocity solution is obtained and substituted into the energy equation, which then is solved by means of a quasi-similarity transformation. The temperature field can be divided into the one-dimensional transient (downstream) region and the quasi-steady-state (upstream) region. Thus the transient local heat transfer coefficient can be described by connecting the quasi-steady-state solution and the one-dimensional transient solution. The non-Darcy porous inertia works to decrease the velocity level and the time required for reaching the steady-state velocity level. The porous-medium inertia delays covering of the plate by the steady-state thermal boundary layer. © 1990.

Approximate solution for non-Darcy transient film condensation in a porous medium

The problem of non-darcian transient film condensation adjacent to a vertical flat plate embedded in a porous medium has been considered. The governing equation for the boundary layer thickness was obtained by an integral method and solved approximately by the method of integral relations. It is shown that the results are in good agreement with those obtained exactly by the method of characteristics.

Antropologia da Civilização: um estudo da tradução para o inglês de termos simples, expressões fixas e semifixas recorrentes em duas obras de Darcy Ribeiro

The main purpose of this article is to investigate the most frequent simple terms as well as fixed and semi-fixed expressions in Social Anthropology of Civilization subarea in Portuguese and their corresponding terms in English, found in two works written by the anthropologist Darcy Ribeiro. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1995, 1996, 1997; CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004; KRIEGER &FINATTO, 2004). Results show that there are similarities and differences among the use of the terms in the main subcorpora composed of source and target texts and in the comparable corpora in Portuguese and in English. This data indicate that terms and expressions are not univocal in the anthropological language due to the differences in the conceptualization of the same referents by different specialists in the area.

A nova teoria da antropologia da civilização: tradução para a língua inglesa de neologismos terminológicos criados por Darcy Ribeiro nas obras o processo civilizatório e o povo brasileiro

This study analyzes the translation process into English of neologisms and expressions in the works written by the anthropologist Darcy Ribeiro and in their respective translations, made by Betty J. Meggers and Gregory Rabassa. Our research project draws on Corpus-Based Translation Studies (BAKER, 1995, 1996, 2000; CAMARGO, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and on some concepts of Terminology (ALVES, 1999; BARROS, 2004; BOULANGER, 1989; CABRÉ, 1993, 1999). Results show that terms do not present similarities within the language related to Brazilian Anthropology, being necessary for the author to look up alternative terminology and to create new concepts that can be used by other anthropologists. The translation of words and expressions developed by the author reflects lexical variation due to the options chosen by the respective translators for the target language. These tendencies may be found in Ribeiro’s translated texts, indicating the difficulty to conceptualize the anthropological Brazilian universe in English.

A tradução para o inglês de termos e expressões em Antropologia da Civilização: traços de explicitação em duas obras de Darcy Ribeiro

The main purpose of this article is to investigate the aspects of explicitation in English translation of terms and expressions in two of Darcy Ribeiro’s anthropological works. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1993, 1995, CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004). According to Baker (1996), explicitation is the tendency to explain, in the translated text, parts of the original text that had been left implicit. Results show that these tendencies may be found in Ribeiro’s translated texts, indicating the difficulty of conceptualizing the Brazilian universe in English.

A tradução para o inglês do léxico tabuizado no universo erótico mairum: um estudo baseado no corpus da obra Maíra de Darcy Ribeiro

The main purpose of this paper is to observe the Portuguese into English translational process regarding the metaphors of specific lexical units related to erogenous zones and to intercourse in the context of the literary work Maira (1978), written by Darcy Ribeiro, as well as in its translation, Maíra (1985), performed by Goodland e Colchie. We based our study on an interdisciplinary proposal that associates the theoretical framework of Lexical Studies (BIDERMAN, 1996; LAKOFF; JOHNSON, 2002; ORSI, 2007, 2009; ORSI; ZAVAGLIA, 2007; 2012; PRETI, 1984; XATARA; RIVA; RIOS, 2002; XATARA, 2004), Corpus-Based Translation Studies (BAKER, 1993, 1995; CAMARGO, 2005), Corpus Linguistics (TYMOCZKO, 1998; BERBER SARDINHA, 2004), and, in part, Terminology (COELHO, 2003; BARROS, 2004; FAULSTICH, 2004). Concerning the methodology, we used the program WordSmith Tools, which provided the tools WordList and Concord, for collection and observation of data. We thus verified the value attributed to the erotic-obscene lexicon in Darcy Ribeiro’s literary-textual construction, and we also analyzed the reformulation of taboo lexicon in English. Finally, we intended to reflect on the process of translation of these lexical units considered socially disreputable, in an attempt to provide a possible support fortranslators, linguists, writers and social scientists.

A simplificação como traço de um habitus tradutório para a Antropologia Brasileira em língua inglesa: um estudo baseado no corpus da oba O Povo Brasileiro de Darcy Ribeiro

The main purpose of this article is to investigate the social and linguistic behaviors of a translator, analyzing the use of simplification aspects in the translational process into English of the Anthropology developed by Darcy Ribeiro. With this aim, we used a parallel corpus composed by the work O povo brasileiro (1995) and by its respective translation, performed by Rabassa. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1993, 1995, 1996; CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004). We also adopted Sociology of Translation theories (SIMEONI, 1998, 2007; GOUANVIC,1999, 2005), as well as the habitus conception, proposed by Bourdieu (1980). Results show that this simplification may be found in Ribeiro’s translated texts, indicating the difficulties of conceptualizing the Brazilian universe in English
