Etnofísica, modelagem matemática, geometria... tudo no mesmo Manzuá

Meu objetivo neste artigo é apresentar os resultados parciais de uma pesquisa em desenvolvimento que visa analisar a Etnofísica dos ribeirinhos amazônicos com o intuito de desenvolver materiais didáticos inovadores para a abordagem de conceitos de Física e Matemática nas aulas do ensino médio e superior em ambiente de Modelagem Matemática. A questão de pesquisa foi: De que maneira a construção do Manzuá pode contextualizar aulas inovadoras de Física e Matemática no ensino médio? A metodologia usada foi abordagem etnográfica. Utilizei como fundamentos teóricos os referenciais da Etnomatemática (D’AMBRÓSIO, 2008), a Teoria dos Modelos Mentais (JONHSON-LAIRD, 1983), Modelagem Matemática (CHAVES e ESPÍRITO SANTO, 2008) e a Teoria dos Campos Conceituais (VERGNAUD, 2007). Os dados iniciais sugerem que o conhecimento físico tradicional do sujeito pesquisado está fortemente relacionado a modelos mentais formados e reformulados em função dos longos anos de prática na construção do Manzuá e que os invariantes operatórios movimentados para construir o artefato fazem parte desses modelos mentais. As situações vivenciadas durante a construção do Manzuá podem embasar ótimas situações-problema para as aulas de Física e Matemática em ambiente de Modelagem Matemática. Podemos, portanto, a partir dessas situações, desenvolver materiais didáticos que relacionem o saber tradicional dos ribeirinhos ao saber da escola

Main Causes of Nonfulfillment of Corneal Donation in Five Hospitals of a Brazilian State

The waiting list for corneal transplantation in Brazil had 6684 patients in June 2012, with great variations in the number of patients among different states. The mean waiting time for a corneal transplant also differs substantially across the states: it is 2 years in State of Espirito Santo (ES) at the time of this study. The aim of the study was to determine the main reasons for nonfulfillment of corneal donation in five ES hospitals. The data collection was performed from March to August 2010. The data were collected using forms completed daily by the Intrahospital Commissions of Organ and Tissues Donation for Transplantation. The total number of deaths was 1347. The main causes of nonfulfillment of donations were medical contraindications (67.86%), logistical/structural problems (27.84%), and family refusal (2.15%). The main medical contraindications were age outside the required range (24.49%), the presence of infectious disease (11.36%), or age outside the range plus infection (15.66%). In 2010, there were 459 people on the waiting list for corneas in ES. Considering the average of failures in these five hospitals multiplied by the number of hospitals in the ES, it seems clear that the solutions to these problems might eliminate the waiting list of the State. In fact, the number of individuals on the waiting list in ES did reach zero in August 2011, after the inauguration of a new Eye Bank that trains employees to interview and perform procurements, in addition to keeping them available in the most important hospitals. Additionally, the maximal age for donation in ES was increased.

ATIVIDADES LÚDICAS NO MEIO AQUÁTICO: POSSIBILIDADES PARA A INCLUSÃO

A pesquisa objetiva compreender e analisar a ação mediadora do professor no desenvolvimento de atividades lúdicas no meio aquático e a interação de uma criança autista com os colegas não deficientes nas aulas. A metodologia baseia-se em um estudo qualitativo do tipo estudo de caso. Os sujeitos foram 14 crianças da Educação Infantil da UFES com desenvolvimento típico e uma com autismo, oriunda da comunidade de Vitória-ES. Conclui que as atividades lúdicas no meio aquático foram benéficas para a criança autista, tanto no sentido da ampliação de seus movimentos e vivências de brincar, como também em suas relações com os professores e colegas.

QUILL MITES IN BRAZILIAN PSITTACINE BIRDS (AVES: PSITTACIFORMES)

The primary and secondary feathers of 170 Brazilian psittacine birds (Aves: Psittaciformes) were examined in order to identify feather quill mite fauna. Birds were held captive in two locations in the state of Minas Gerais (MG), and two in the state of Espirito Santo (ES). The quills were cut longitudinally and were examined under optical microscopy. The genus of quill mites most frequently found was Paralgopsis (Astigmata: Pyrogliphidae), followed by Cystoidosoma (Astigmata: Syringobiidae). Astigmata: Syringophilidae mites were sporadically observed. After analyzing the data using logistic regression models, it was determined that there was higher infestation risk for psittacines in ES state, as compared with those in MG, and a significant increase in risk depending on the psittacine host species. However, the location of captivity did not have a significant effect. Lesions were observed in infested feathers. Cystoidosoma sp. and Paralgopsis sp. were always observed together, with parts of Paralgopsis found inside Cystoidosoma sp., suggesting thanatochresis or predation.

Número de postos pluviométricos necessários para a estimativa da precipitação mensal no estado do Espírito Santo, Brasil

Os objetivos propostos nesse trabalho foram, determinar a distribuição espacial da precipitação pluvial média mensal no Estado, utilizando a altitude dos postos pluviométricos como co-variável e, determinar o número de postos necessários para mapear a precipitação, considerando a dependência espacial. Os dados para realização desse estudo abrangem séries variando de 33 a 72 anos, totalizando 55 postos pluviométricos. Os dados foram submetidos a uma análise descritiva e geoestatística. A co-krigagem usando a altitude como co-variável apresentou considerável acurácia na estimativa da precipitação. A utilização do alcance do variograma cruzado reduziu o número necessário para 37 postos pluviométricos no Estado, para estudar a precipitação média mensal com dependência espacial.

Occurrence of Tomato chlorosis virus in tomato crops in five Brazilian states

Tomato chlorosis virus (ToCV) is a species in the genus Crinivirus, transmitted by Bemisia tabaci biotype B, first detected in Brazil in 2006 in the county of Sumare, State of Sao Paulo. During the period from 2007 to 2010, RT-PCR analyses followed by nested-PCR with specific primers for ToCV detection, and sequencing of the amplicons, confirmed the presence of this virus in samples of symptomatic tomato plants (Solanum lycopersicum) from crops in counties in the states of Bahia (BA), Espirito Santo (ES), Goias (GO), Minas Gerais (MG), and Rio de Janeiro (RJ). This is the first ToCV report for the states of BA, ES, GO, MG, and RJ, suggesting that this virus is widely disseminated in Brazil.

Evaluation of cetacean exposure to organotin compounds in Brazilian waters through hepatic total tin concentrations

In Brazil, there is no restriction to the use of organotins (OTs). Previous investigations have shown that hepatic SigmaSn in cetaceans is predominantly organic. Hepatic SigmaSn concentrations were determined by GFAAS in 67 cetaceans (13 species) that stranded on Rio de Janeiro (RJ) and Espirito Santo (ES) states. Concentrations (in ng/g wet wt.) of marine tucuxis (n=20) from the highly contaminated Guanabara Bay (in RJ) varied from 1703 to 9638. Concentrations of three marine tucuxi foetuses and one newborn calf (all from Guanabara Bay) varied between 431 and 2107. Contrastingly, the maximum level among 19 oceanic dolphins was 346, and 15 out of these 19 specimens presented concentrations below detection limit. The levels of Sn in six marine tucuxis from a less contaminated area (ES) varied from below detection limit to 744. Comparing to the literature, coastal cetaceans from Brazil appear to be highly exposed to OTs.

Formação de professores de inglês em nível universitário no Espírito Santo: uma avaliação através da voz de instituições, professores e estudantes

O presente estudo é um recorte de uma dissertação de mestrado que investigou a situação da formação de professores de inglês como LE no estado do Espírito Santo (ES). Através de uma pesquisa de levantamento de dados em quatro instituições capixabas que oferecem o curso de Letras/Inglês, levantamos, tabulamos e categorizamos dados, processo que nos levou a uma avaliação global da formação de professores de Inglês no ES. Os resultados revelaram o perfil dos respondentes aos questionários de pesquisa - administradores, professores e estudantes - bem como suas avaliações sobre as condições físicas de cada uma das instituições pesquisadas e a qualidade do curso que oferecem. Embora não negativa, a formação de professores de inglês nos cursos oferecidos por essas quatro instituições do ES ainda está longe daquilo que é desejado por seus estudantes, professores e administradores.

Charnoquitóides do maciço de Várzea Alegre: um novo exemplo do magmatismo Ca-alcalino de alto K no arco magmático do Espírito Santo

CHARNOCKITIC ROCKS OF THE VA RZEA ALEGRE MASSIF: A NEW EXAMPLE OF THE HIGH K CA-ALKALIC MAGMATISM IN THE MAGMATIC ARC OF THE ESPIRITO SANTO The Varzea Alegre intrusive massif is situated in the central portion of the Espirito Santo State. It is an example of the late to post tectonic magmatism related to the onset of a magmatic are developed during the late-Brasiliano episode. It comprises an inner domain of gabbros, diorites, quartz-diorites and granites completely surrounded by a large ring of charnockitic rocks. The lithotypes found in that ring were chemically classified as opdalites, jotunites, quartz mangerites and enderbites (opx-quartz diorites). They show aporphyritic texture with feldspars and quartz megacrysts set in a medium to coarse grained matrix. The geochemical characteristics of these rocks are typical of a calc-alkalic magmatism enriched in LIL and HFS elements (mainly Ba, K, REE, Zr, P and Nb). Using compatible versus incompatible elements variation diagrams it is possible to sugest that fractional crystalization and magma mixing were the principal mechanisms in the evolution of the suite. The high contents in such incompatible elements point towards a mantelic contribution associated with crustal contamination for the genesis of the rocks.

Siphonophora from the coast of Brazil (17ºS to 24ºS)

This work is based on the analysis of 99 zooplankton samples collected during the Oceanographic Expedition ESPIRITO SANTO I, held along the east coast of Brazil, between Cabo Frio and Abrolhos Archipelago, an area characterized by the occurrence of coastal upwelling, from July to September 1984. Zooplankton was collected with vertical plankton net hauls of 250 µm mesh size in the upper 200 meters layer. A total of twenty one species of Siphonophora was observed, two of which were identified as being physonect and the other as calycophorans. Specific diversity close to the shore and at the neighborhood of the Vitoria-Trindade Bank System, showed smaller values, in comparison with those in the oceanic regions. Factorial analysis was used in order to access the changes observed in the population of the eleven most abundant species. The first two principal axes represented the influence of the nearshore - offshore gradient and the role of trophic interaction, accounted for 60% of the total variance of the data.
