Fantasia e conhecimento: um estudo crítico preliminar
Mola, Luis Guilherme Coelho;
Psicologia USP , 1999, DOI: 10.1590/S0103-65641999000200003
Abstract: the purpose of this article is to discuss the role played by imagination in the process of knowledge production. using as theoretical support the ideas of some philosophers of the frankfurt school, the text attempts to demonstrate that imagination has a critical function, denied by positivism, which could contribute for the questioning of the organization of society.
Fantasia e conhecimento: um estudo crítico preliminar
Mola Luis Guilherme Coelho
Psicologia USP , 1999,
Abstract: Neste artigo discute-se o lugar ocupado pela fantasia no processo de produ o do conhecimento. A partir do referencial fornecido por autores ligados à Escola de Frankfurt, procurou-se demonstrar que a fantasia possui uma fun o crítica, negada pela concep o positivista de ciência, que pode contribuir para o questionamento da maneira pela qual a realidade se encontra constituída.
Cardiopulmonary effects and eyeball centralization with low-dose atracurium in spontaneously breathing, anesthetized dogs
Carregaro, Adriano Bonfim;Freitas, Gabrielle Coelho;Cruz, Fernando Silvério Ferreira da;Machado, Melissa;Tognoli, Guilherme Kanciukaitis;Pippi, Ney Luis;
Ciência Rural , 2010, DOI: 10.1590/S0103-84782010005000118
Abstract: the objective was to determine the cardiopulmonary effects and eyeball centralization time obtained with 15 or 30μg kg-1 of atracurium in anesthetized dogs under spontaneous breathing. eighteen healthy adult mixed-breed dogs were used, which received 0.1mg kg-1 acepromazine and 0.5mg kg-1 morphine im, followed by 4mg kg-1 propofol iv and maintained on isoflurane anesthesia with spontaneous breathing. animals received 1ml 0.9% nacl iv (cg), 15μg kg-1 (g15) or 30μg kg-1 (g30) of atracurium iv. eyeball centralization time was measured; heart rate (hr), systolic (sap), mean (map) and diastolic (dap) arterial pressures, respiratory rate (rr), tidal volume (vt) and minute volume (vm) were determined every 5min, and ph, arterial co2 pressure (paco2 ), arterial o2 pressure (pao2 ), hemoglobin oxygen saturation (sao2 ), bicarbonate (hco3-) and base excess (be) every 15min until 60min. both doses of atracurium produced a similar period of eyeball centralization. vt in groups treated with atracurium was lower than in cg up to 15min. vm in g15 differed from cg up to 10min and in g30 up to 25min. no differences were observed for cardiovascular parameters, rr, sao2, pao2, hco3- and be. ph decreased in cg between 30 and 60min and in g15 and g30 at 15min. g30 differed from cg between 15 and 30min. paco2 in gc differed from baseline between 30 and 60min and in g15 differed at 15min. atracurium at the dose of 15μg kg-1 is adequate for short corneal procedures in inhalant-anesthetized dogs under spontaneous breathing.
Phase diagram and water-like anomalies in core-softened shoulder-dumbbells system
Cristina Gavazzoni,Guilherme K. Gonzatti,Luiz Felipe Pereira,Luis Henrique Coelho Ramos,Paulo A. Netz,Marcia C. Barbosa
Physics , 2013,
Abstract: Using molecular dynamics we studied the role of the anisotropy on the phase boundary and on the anomalous behavior of 250 dimeric particles interacting by a core-softened potential. This study led us to an unexpected result: the introduction of a rather small anisotropy, quantified by the distance between the particles inside each dimer, leads to the increase of the size of the regions in the pressure-temperature phase diagram of anomalies when compared to the isotropic monomeric case. However, as the anisotropy increases beyond a threshold the anomalous regions shrinks. We found that this behavior can be understood by decoupling the translational and non-translational kinetic energy components into different translational and non-translational temperatures.
Os espanhóis canibais: análise das gravuras do sétimo volume das Grands Voyages de Theodore de Bry
Kalil, Luis Guilherme Assis;
Tempo , 2011, DOI: 10.1590/S1413-77042011000200011
Abstract: the article analyses the images done by theodore de bry and their descendants for the grand voyages, collection of reports about the new world published between the 16th and the 17th centuries. from the seventh volume, dedicated to the viaje al río de la plata, from the bavarian soldier ulrico schmidl, we seek to analyze the representations of the indians and of the spaniards that were presented in the images done by the protestant editor.

Mahotas: Open source software for scriptable computer vision
Luis Pedro Coelho
Computer Science , 2012, DOI: 10.5334/jors.ac
Abstract: Mahotas is a computer vision library for Python. It contains traditional image processing functionality such as filtering and morphological operations as well as more modern computer vision functions for feature computation, including interest point detection and local descriptors. The interface is in Python, a dynamic programming language, which is very appropriate for fast development, but the algorithms are implemented in C++ and are tuned for speed. The library is designed to fit in with the scientific software ecosystem in this language and can leverage the existing infrastructure developed in that language. Mahotas is released under a liberal open source license (MIT License) and is available from (http://github.com/luispedro/mahotas) and from the Python Package Index (http://pypi.python.org/pypi/mahotas).
The Shadow Moiré method using the phase shifting technique and digital image processing: computational implementation and application to the 3D-reconstruction of a buckled plate
Smith Neto, Perrin;Coelho, Guilherme Cremasco;
Journal of the Brazilian Society of Mechanical Sciences , 2000, DOI: 10.1590/S0100-73862000000300003
Abstract: the shadow moiré fringe patterns are level lines of equal depth generated by interference between a master grid and its shadow projected on the surface. in simplistic approach, the minimum error is about the order of the master grid pitch, that is, always larger than 0,1 mm, resulting in an experimental technique of low precision. the use of a phase shift increases the accuracy of the shadow moiré technique. the current work uses the phase shifting method to determine the surfaces three-dimensional shape using isothamic fringe patterns and digital image processing. the current study presents the method and applies it to images obtained by simulation for error evaluation, as well as to a buckled plate, obtaining excellent results. the method hands itself particularly useful to decrease the errors in the interpretation of the moiré fringes that can adversely affect the calculations of displacements in pieces containing many concave and convex regions in relatively small areas.
A GEOGRAFIA E HISTóRIAS EM QUADRINHOS
Luís Guilherme da Silva Coelho
Revista Tamoios , 2005,
Abstract: A cultura de massa consiste de meios de comunica o que interferem na difus o de diversos valores culturais, o que dá falsa idéia de um universalismo. As revistas em quadrinhos s o um exemplo de meio de comunica o, é como os demais produtos criados para o lazer, que seguem a lógica globalizante, uma vez que acompanham as mudan as das técnicas de produ o e atingem a sociedade, porém antes de tudo é preciso observar e analisar o seu conteúdo, sua mensagem, sendo importante compreender sua estrutura constituída de mitos e signos. As revistas de histórias em quadrinhos se inserem no capitalismo primeiramente como mercadoria, possuindo um valor de troca e segundo, difundindo ideologias, apresentando-se como um produto inocente e divertido, o que permite a sua aceita o e sua linguagem é de fácil entendimento, tornando-a acessível principalmente para as crian as, n o é preciso nenhum conhecimento a mais para ler uma história, somente o essencial: saber ler. Palavras-chave: Geografia; história em quadrinhos; cultura; ideologia; economia.
