Dinamica de Sala de Aula: uma variável na aprendizagem
Reinoldo Marquezan,Angela Meincke Melo,Graciela F. Rodrigues,Daniele Noal
Revista Educa??o Especial , 2012, DOI: 10.5902/1984686x5005
Abstract: A dinamica da aprendizagem se dá através de intera es mútuas, nas quais alunos e professores estabelecem rela es sociais e afetivas. Na sala de aula essas rela es se orientam para promover e efetivar a aprendizagem formal. Neste artigo apresentamos os resultados da pesquisa que teve como objetivo interagir com o professor de modo intencional, subsidiando-o para aumentar as situa es de troca entre seus alunos. Primeiramente identificou-se a estrutura sócio-afetiva dos grupos, utilizando como instrumento o Teste Sociométrico. No segundo momento realizamos com os docentes, encontros nos quais abordou-se quest es referentes a dinamica de grupo e as concep es construtivistas de aprendizagem. Acreditamos que, conforme a Teoria Construtivista da aprendizagem, a intera o e as trocas entre os membros constituintes do grupo de sala de aula é fundamental para a aquisi o de uma aprendizagem significativa para os educandos. Palavras-chave: dinamica de grupo, aprendizagem, sala de aula.
Experimental and theorical study of the air quality in a suburban industrial-residential area in Rio de Janeiro, Brazil
Rodrigues, Fernanda;Milas, Ivan;Martins, Eduardo M.;Arbilla, Graciela;Bauerfeldt, Glauco F.;Paula, Murilo de;
Journal of the Brazilian Chemical Society , 2007, DOI: 10.1590/S0103-50532007000200015
Abstract: in this work, data for criteria and non-criteria pollutants were obtained in a suburban industrial-residential area in rio de janeiro, from april to november 2002. formaldehyde and acetaldehyde concentrations were found in the ranges 25.25-231.73 ppb and 9.48-75.74 ppb, respectively. these high concentrations may be attributed to several sources: vehicular and industrial emissions, the presence of several trash incinerators, effluents and waste rejected in the faria timbó river and emissions from a methanol industry. average btex concentrations were: 1.92, 9.02, 6.37, 21.65 and 5.99 μg m-3 for benzene, toluene, ethylbenzene, m,p-xylene and o-xylene, respectively. pm10 concentrations showed maximum mean values in october, april and june. simulated concentrations were obtained for august 2002 using a trajectory model. the maximum calculated ozone concentration was 39.8 ppb, at 3:00 pm, in good agreement with experimental data (38.5 ppb). the ozone isopleths show that the local is in the high voc/nox region, typical of suburban and downwind areas.
Alfabetiza o de surdos: apontando desafios
Graciela Rodrigues,Helenise Sangoi Antunes
Revista Educa??o Especial , 2003,
Abstract: Com o propósito de fazer algumas reflex es acerca desta etapa de escolariza o, considerada uma das mais significativas dentro do processo de ensino aprendizagem, este trabalho abordará algumas quest es referentes ao processo de alfabetiza o de alunos surdos. A partir de uma análise na qual a Língua de Sinais-LS é apontada como um dos caminhos que tem sido reveladores de uma prática pedagógica que leva em considera o as diversidades destes educandos, alguns desafios configuram-se no trabalho docente e que somente um educador comprometido com as mudan as e consciente que educa o é um direito de todos, conseguirá efetivar um trabalho reflexivo com a realidade. Palavras-chave: surdos, alfabetiza o, Língua de Sinais.

Mujer campesina y trabajo. Su rol en la actividad productiva y reproductiva de los Valles Calchaquíes
Graciela F. Torres
Andes , 2004,
Abstract: En este artículo se aborda el trabajo femenino en la sociedad campesina del departamento San Carlos, ubicado en los Valles Calchaquíes, en jurisdicción de la provincia de Salta. Se considera la percepción social del rol de la mujer en vinculación al trabajo, y en consecuencia se realiza un inventario de todas las tareas consideradas femeninas, reproductivas y productivas. También se indaga acerca del concepto de trabajo y se analiza su contribución a la supervivencia del grupo doméstico, es decir su importancia como agente económico capaz de obtener y generar ingresos tanto monetarios como en bienes y productos. En la investigación se utilizó metodología cualitativa y las informantes fueron mujeres adultas con un grupo familiar a cargo

Megalithic Constructions Discovered in the Azores, Portugal  [PDF]
António Félix Rodrigues
Archaeological Discovery (AD) , 2015, DOI: 10.4236/ad.2015.32006
Abstract: The oldest cave art known is of prehistoric origin, dating back to approximately 40,000 years ago in both Asia and Europe. The megalithic constructions in Western Europe and the Mediterranean Region took place mainly in the Neolithic and continued until the Chalcolithic and Bronze Age. The Azores Islands did not seem to have been occupied before the arrival of the Portuguese navigators in the XVth century. Because of that, it was not expected that megalithic structures would be found, or structures that resembled megalithic tombs and rock art in the Azores Islands, geographically located in the Center of the North Atlantic, at 1500 km west of Lisbon (Portugal) and about 1900 km southeast of Newfoundland (Canada). These findings seem to be, historically, a paradox. In a first moment, an oral presentation was made about these findings by the author at the 16th Annual Mediterranean Studies Association Congress, and after that, a field trip took place with the archeologists present at the stated Congress. The perplexity was the dominant conduct of the guests, and some hypotheses that certain archaeologists mentioned were evolved versions which had not been empirically corroborated. Afterwards, new findings were registered at Grota do Medo site, helping to make clear that larger stones had been used to construct structures or monuments. The rock art surrounding the megalithic constructions in the Azores also has similarities with those found in Europe. If these findings belong to the Bronze Age or Iron Age, it can reopen new scientific questions about ancient mid-Atlantic crossings. The present article tries to establish ties among the megalith constructions found in the Azores with those known in Europe.
Kinetic analysis of the chemical processes in the decomposition of gaseous dielectrics by a non-equilibrium plasma - part 1: CF4 and CF4/O2
Bauerfeldt, Glauco F.;Arbilla, Graciela;
Journal of the Brazilian Chemical Society , 2000, DOI: 10.1590/S0103-50532000000200004
Abstract: numerical integration of the coupled differential equations which describe a chemical reacting system and sensitivity analysis are becoming increasingly important tools in chemical kinetics. in this work, a numerical modelling analysis of the chemical processes in the gas-phase decomposition of pure cf4 and cf4/o2 mixtures, in the presence of silicon, was performed. the relative importance of individual processes was analysed and the sensitivity coefficients as well as the effect of the parameters uncertainties were determined . the results were compared with experimental data from the literature to adjust the model parameters. the main etching agent in the system is the fluorine atom. the concentrations of the main species (sif4, co, co2 and cof2) depend on the composition of the mixture.
Kinetic analysis of the chemical processes in the decomposition of gaseous dielectrics by a non-equilibrium plasma - part 2: SF6 and SF6/O2
Bauerfeldt, Glauco F.;Arbilla, Graciela;
Journal of the Brazilian Chemical Society , 2000, DOI: 10.1590/S0103-50532000000200005
Abstract: in this work, a numerical modelling analysis of the gas-phase decomposition of pure sf6 and sf6/o2 mixtures, in the presence of silicon was performed. the relative rate of individual processes, the effect of the parameters uncertainties and the sensitivity coefficients were determined. the results were compared with literature experimental data for the plasma etching of silicon and with previous simulated results to adjust the model parameters. as in the cf4 system, the main etching agent is atomic fluorine and the concentration of the major species depends on the composition of the mixture. the shape of the sensitivity curves follows the general shape of the individual rate curves and the ratio between the calculated sensitivity coefficients is closely related to the contribution of each reaction.
