História da Historiografia , 2012,
Abstract: Este artigo visa a apresentar a forma como a historiografia tradicional incorporou o cinema entre seus objetos de pesquisas por meio de um diálogo ambíguo com os estudos do cinema e pela exclus o direta da história do cinema. Acompanha-se a inclus o do cinema entre os objetos da historiografia francesa e brasileira, a domestica o do filme na opera o historiográfica e a sobrevivência dos marcos iniciais dessa inclus o no atual momento das pesquisas, bem como os deslocamentos mais importantes dos últimos dez anos. Observaremos alguns aspectos da história da constitui o do cinema como objeto historiográfico, propondo, ao final, um diálogo sistemático com a teoria da história e a própria história do cinema.

Revista Brasileira de Ginecologia e Obstetrícia , 2002,
Abstract: Objetivo: determinar a presen a de infec o assintomática do líquido amniótico em gestantes, identificar os agentes bacterianos envolvidos na infec o e determinar o perfil de suscetibilidade a antimicrobianos in vitro. Métodos: foram obtidas 81 amostras de líquido amniótico, colhidas por amniocentese, em gestantes sem sinais de trabalho de parto e sem suspeita clínica de infec o, atendidas na Maternidade Escola Assis Chateaubriand, entre agosto/97 e janeiro/99. Pesquisou-se a presen a de bactérias aeróbias, anaeróbias estritas/facultativas e micoplasmas genitais. As bactérias anaeróbias foram identificadas pelo sistema ATBò (Bio-Mérieux) e os micoplasmas pelo kit Micoplasmas ISTò (Bio-Mérieux). Resultados: entre as amostras obtidas, oito (9,8%) apresentaram culturas positivas, sendo que em duas foram identificadas duas espécies bacterianas. Os patógenos isolados foram: Ureaplasma urealyticum (7 casos, 8,6%), Mycoplasma hominis (1 caso, 1,2%) e Peptostreptococcus sp (2 casos 2,4%). O padr o de resistência aos antimicrobianos caracterizou-se pela maior resistência dos micoplasmas à eritromicina (37,5%) e nenhuma resistência às ciclinas. Conclus es: o percentual de infec es assintomáticas foi muito elevado, havendo necessidade de serem realizadas novas pesquisas para avaliar as conseqüências da infec o subclínica nas grávidas e em seus conceptos, que envolvam métodos que identifiquem micoplasmas genitais, já que foram as bactérias mais freqüentemente isoladas.

Abstract: this work presents a verification study of rainfall forecast by a regional model ensemble prediction system. the ensemble is formed by six members; four of them using rams 6.0, and two using wrf 3.1, all initialized by cptec or gfs general circulation model data and making use of different convection parameterizations. the verification focuses on rainfall forecasts for 24, 48 and 72 hours and rainfall thresholds of 1 mm, 5 mm and 10 mm over the ceará state. all ensemble members have better skill than persistence in the entire verification domain. rams shows a larger accuracy, especially at the northern coast of ceará, but gives also a larger false alarm ratio than wrf model. the quality of the rainfall forecasts system decreases as either, the rainfall intensity or the forecast horizon time increase.

Abstract: this paper evaluated the effect of hydraulic retention time (hrt) on the performance of three upflow aerobic reactors, with polyurethane foam as support material, inoculated with aspergillus niger an400, used for the treatment of petroleum refinery wastewater. each reactor was operated with a different hrt: 4, 8 and 12 hours, during 152 days. the performance was evaluated based on ph; phenols; cod, nitrate and nitrite. the results show that for the cod removal, it is more reasonable to operate the reactor with hrt of eight hours. however, there was no difference among results of phenol removal efficiency of the different hrts. during steady state condition, nitrite was removed in approximately 99%, but there was no reduction on the nitrate concentration. ammonia was produced in all reactors, probably due to ammonification of nitrite.
