Abstract: the exocarp and external mesocarp of pequi fruit are discarded during the extraction of internal mesocarp which is the commercial part used as food. the objective of this research was to study the use of aqueous extract and of pequi ground-powder to the control of root-knot nematode (meloidogyne javanica). from ground pequi fruit exocarp and external mesocarp were obtained the aquaeous extract and powder. five doses of aquaeous extract (0.0; 2.5; 5; 10 or 20%) were evaluated on root-knot nematode j2 (second stage juvenile) hatching and mortality. the assays were carried out in entirely randomized design with 10 replications. the hatching assay was set in petri plates with 800 nematode eggs and 10 ml of different doses of extract. during 14 days we counted the number of hatched juveniles under optical microscope. the mortality assay of root-knot nematode was evaluated putting 100 μl of each dose of extract plus 20 μl of supension containing 20 j2 in each cell elisa plate. after 24 h was counted the number of live and dead juveniles. the pequi powder was tested in tomato plants in greenhouse in four doses (0; 7.5; 15 or 30 g/4 kg of soil) in randomized blocks design with 10 replications per treatment. the pequi powder was incorporated to the soil seven days before transplanting and nematode eggs inoculation was carried out after transplanting. after 40 days we evaluated the number of galls, egg masses, eggs/root and j2 per 200 cm3 soil and the tomato shoot dry weight and height. the aquaeous extract reduced j2 hatching and increased j2 mortality. the increased application of powder doses reduced the number of galls, egg masses and eggs of root-knot nematodes per root system and the tomato shoot dry weight being a good indication of phytotoxicity.

Flores, Cláudia Regina;
Bolema: Boletim de Educa??o Matemática , 2012, DOI: 10.1590/S0103-636X2012000100006
Abstract: this paper focuses on the analysis of one way of looking at and representing plans of military forts. theoretical assumptions come from the reflections on the construction and representation of militarized space in mathematical activity, to understand how the operation of perception has become geometrical and how they have created and used mathematical knowledge to represent using technical perspective theory. analysis is conducted of military plans or architectural designs of american forts in the seventeenth and eighteenth centuries, in accordance with the teachings and rules found in the treaties of military engineering. we conclude that mathematical knowledge applied to an historical practice can be an exercise, in teacher education, to understand practices of looking in mathematics education as well as to develop activities of visualization in the teaching and learning of mathematics.
A importancia da press?o pleural na avalia??o da mecanica respiratória
Fernandes, Cláudia Regina;
Revista Brasileira de Anestesiologia , 2006, DOI: 10.1590/S0034-70942006000300009
Abstract: background and objectives: pleural pressure has to be known for the partitioning of respiratory system mechanical measurements into their lung and chest wall components. this review aimed at discussing alternative methods to obtain pleural pressure to calculate pulmonary mechanics, at reporting peculiarities of the esophageal balloon method for obtaining indirect pleural pressure, peculiarities of esophageal pressure measurement in sedated or anesthetized patients, at discussing direct pleural pressure and its correlation with esophageal pressure, in addition to reporting on the impact of peep on pleural and esophageal pressures. contents: esophageal pressure variation reflects pleural pressure variation and may be used as alternative to direct pleural pressure in the study of lungs and chest wall mechanics. esophageal pressure may be obtained with a delicate balloon placed inside the esophagus. method and technique were observed and validated in humans and animals in different conditions and body positions. peep is a consolidated method for patients under mechanically controlled ventilation, however there are controversies about the close correlation between esophageal and pleural pressure in patients ventilated with peep, which may result in wrong respiratory mechanics calculation based on the esophageal pressure. conclusions: the esophageal balloon is the most common method to obtain indirect pleural pressure. in sedated or anesthetized patients without major respiratory compliance changes, esophageal pressure variation corresponds to pleural pressure variation when peep is applied.

Abstract: Este artigo analisa a trajetória do Instituto Histórico e Geográfico Brasileiro e do Instituto Histórico e Geográfico de Minas Gerais, observando-os no contexto de sua forma o e atua o. A produ o do saber e a elite política confundiam-se nos dois momentos, sendo que, durante o Império, a leitura da história reiterava a existência da Monarquia. Após 1889, caberia ao IHGMG a recupera o da Inconfidência Mineira sob o aspecto de modelo republicano fundador da História do Brasil. A produ o didática refor ou, nos dois casos, a orienta o oferecida pelos Institutos Históricos.
A importancia da press o pleural na avalia o da mecanica respiratória
Fernandes Cláudia Regina
Revista Brasileira de Anestesiologia , 2006,
Abstract: JUSTIFICATIVA E OBJETIVOS: Para a parti o das medidas de mecanica do sistema respiratório em seus componentes pulm o e parede torácica, faz-se necessário o conhecimento da press o pleural. A finalidade desta revis o foi discutir sobre medidas alternativas à obten o da press o pleural para o cálculo da mecanica pulmonar, relatar as peculiaridades do método do bal o esofágico para obten o indireta da press o pleural, as particularidades da obten o da medida da press o esofágica em pacientes sedados ou anestesiados, discorrer sobre a medida direta da press o pleural e sua correla o com a press o esofágica, assim como relatar sobre o reflexo da PEEP nas press es pleural e esofágica. CONTEúDO: A varia o da press o intra-esofágica reflete a varia o da press o intrapleural, podendo ser usada como medida alternativa à press o pleural direta, no estudo da mecanica dos componentes pulm o e parede do sistema respiratório. A medida da press o esofágica pode ser realizada por meio de um delicado bal o posicionado no interior do es fago. O método e a técnica foram observados e validados em seres humanos e animais em diferentes condi es e posturas corporais. O emprego da PEEP em pacientes sob ventila o controlada mecanica está consolidado; no entanto, existem controvérsias da correla o próxima entre a press o esofágica e a press o pleural em pacientes ventilados com PEEP, o que pode resultar em erros de cálculo de mecanica respiratória considerando a press o esofágica. CONCLUS ES: O método do bal o esofágico é o mais utilizado para a obten o da medida indireta da press o pleural. Em pacientes sedados ou anestesiados sem altera es significativas da complacência respiratória, a varia o da press o esofágica corresponde à varia o da press o pleural quando a PEEP é aplicada.
Semiotic representation in Mathematics: history, epistemology, learning Registros de representa o semiótica em matemática: história, epistemologia, aprendizagem
Cláudia Regina Flores
Bolema: Boletim de Educa??o Matemática , 2008,
Abstract: Since the works of Raymond Duval, the question regarding the role of records of semiotic representation in the learning of Mathematics has been an object of research. There is no doubt that records of semiotic representation are essential for the creation of mathematical objects, as well as for the learning of Mathematics. The subject of this text is, therefore, to offer some reflections on the way of thinking which gives foundation to this hypothesis. How did the idea of representation, particularly semiotic representation, become the model for the acquisition of knowledge within a specific line of thought? It can be said that the representation records theory, elaborated by Duval, for the learning of Mathematics, has modern thought as a base: a cognoscenti subject, a cognoscible object and a dual theory of signs. This analysis becomes particularly important for making possible a deeper reflection, especially in the education of Mathematics teachers, in regard to the learning theories which are employed, as well as the formation of the knowledge which is taught in Mathematics. Key words: Representation. Semiotics. History of Mathematics. Mathematics Education. A partir dos estudos de Raymond Duval, a quest o do papel dos registros de representa o semiótica para a aprendizagem matemática tem sido foco de pesquisas, em educa o matemática. N o há dúvida de que os registros de representa o semiótica s o essenciais tanto para a cria o de objetos matemáticos como para a sua apreens o. A quest o neste artigo é, ent o, trazer algumas reflex es sobre o modo de pensamento que fundamenta esta hipótese. Como a idéia de representa o, particularmente de representa o semiótica, se constituiu como o modelo para aquisi o do conhecimento dentro de um regime de pensamento? Pode-se afirmar que o estudo sobre os registros de representa o semiótica, empreendido por Duval, tem como base o pensamento moderno: um sujeito cognoscente, um objeto cognoscível e uma teoria dual dos signos. Esta análise se faz importante por possibilitar reflex es profundas, particularmente, na forma o de professores de matemática, acerca das teorias de aprendizagem que se pratica, bem como da própria constitui o dos saberes que se ensina em matemática. Palavras-chave: Representa o. Semiótica. História da Matemática. Educa o Matemática.
REFLECTIONS ON THE FUNCTION OF REFERENCE LIBRARIAN IN THE SCIENTIFIC COMMUNICATION TRANSFER
Cláudia Regina dos Anjos
Biblionline , 2012,
Abstract: The assignment of the reference librarian of the university goes beyond its role as facilitator of information. Today he also works as an educator and promote training programs that teach students and researchers to standardize their academic-scientific works, as standards of the Brazilian Association of Technical Standards (ABNT). This paper discusses the problem of standardization of academic and scientific work in the universities. The methodology consisted of the review of work Completion of Course Work (CCW). The task of reviewing the academic and scientific work, which would be easy at first, becomes complicated by the difficulty of working together with the teacher librarian and the lack of the teacher librarian is also an education professional standards and that the documentary exist to facilitate the transfer of scientific communication.
