Frequência e riqueza de cupins em áreas de plantio de eucalipto no litoral norte da Bahia

O objetivo deste trabalho foi avaliar a frequência e a riqueza de espécies de cupins que ocorrem em áreas de reflorestamento com eucalipto. As amostras foram coletadas em três áreas de Eucalyptus recém-colhido, em dezembro de 2005, por meio de seis transectos de 100 m de comprimento por 2-m de largura, subdivididos em 20 parcelas (2x5 m) contíguas. Cada parcela foi amostrada por uma hora por pessoa, e de cada subdivisão foram retiradas 12 amostras de 20x20x20 cm de profundidade, das quais foram coletadas 21-espécies de cupins, pertencentes a duas famílias e 16 gêneros. Dez espécies foram consideradas dominantes, todas da família Termitidae, das quais as de maior frequência foram Amitermes amifer e Nasutitermes corniger. O grupo funcional xilófago teve o maior número de espécies (11) e a maior frequência. Espécies conhecidas como pragas em eucalipto tiveram frequência abaixo do limite de dominância

La Misión Indígena San Francisco Solano de Tacaaglé en las tierras fiscales de Formosa (1900-1950)

[spa]La Misión Indígena fue inaugurada en el año 1901, en la zona del río Pilcomayo del Territorio Nacional de Formosa, precisamente al costado de la concesión paraguaya otorgada a Elisa (Elizabeth Alicia) Lynch. Desde entonces, fue trasladada, primero a Tacaaglé en 1902, donde adquirió el nombre de Misión San Francisco Solano, y posteriormente, en 1915, al riacho El Porteño. Los misioneros franciscanos asumieron la tarea de formar a “colonos indígenas” tobas y pilagás para la producción de azúcar. Se analiza la evolución de la Misión franciscana y el impacto de la llegada del Ferrocarril de Formosa a Embarcación (F.C.F.E.). La documentación utilizada se encuentra en la Biblioteca y Archivo Históricos de la Provincia Franciscana de San Miguel, del Museo Conventual de San Carlos Borromeo ubicado en San Lorenzo, Provincia de Santa Fe

Dificuldades diagnósticas no osteoma osteoide do cotovelo: estudo clínico, radiológico e histopatológico

OBJETIVO: Descrever os aspectos clínicos e de imagem que podem auxiliar no diagnóstico correto do osteoma osteoide no cotovelo. MATERIAIS E MÉTODOS: Realizado estudo retrospectivo de sete pacientes com diagnóstico de osteoma osteoide no cotovelo confirmado histologicamente por biópsia óssea. Eles tiveram seus prontuários médicos e exames de imagem revisados. RESULTADOS: Do total de 142 pacientes identificados em nossos arquivos, 4,9% apresentavam a lesão no cotovelo, com predomínio no sexo masculino (2,5:1) e idade média de 25 anos. Dor e limitação de movimento foram os sintomas mais comuns. Cinco pacientes (71,4%) receberam outro diagnóstico clínico prévio. A duração média dos sintomas foi de 21 meses. As radiografias não demonstraram o nidus em 42,8% dos casos. A tomografia computadorizada e a ressonância magnética mostraram claramente o nidus. Derrame articular foi um achado constante. O aspecto histológico observado foi o usual. A ressecção cirúrgica promoveu alívio dos sintomas e/ou melhora funcional em todos os casos. CONCLUSÃO: É importante considerar a possibilidade de osteoma osteoide em paciente adulto jovem com dor, limitação do movimento e sinais de sinovite no cotovelo, refratária ao tratamento conservador. Esclerose óssea, espessamento cortical e/ou reação periosteal detectados na radiografia permitem direcionar a tomografia computadorizada para a visualização precisa do nidus.

Los indígenas sanapanás, Carlos Casado y las fotografias de de Sanctis

El español Carlos Casado del Alisal se estableció en la ciudad de Rosario en el año 1857, y configuró un importante número de empresas dedicadas a la producción del trigo, del quebracho colorado de la zona del Chaco Paraguayo, y en especial a la exportación de ambos recursos desde el Puerto de Rosario a Europa y a los Estados Unidos. En este artículo nos referimos a la colaboración que hizo el español republicano Matías Alonso Criado al facilitar a Casado la llegada de la Orden Salesiana a la zona costera del Chaco con la finalidad de "educar" a los indígenas sanapanás.

A Case-based reasoning approach to validate grammatical gender and number agreement in Spanish language

Across Latin America 420 indigenous languages are spoken. Spanish is considered a second language in indigenous communities and is progressively introduced in education. However, most of the tools to support teaching processes of a second language have been developed for the most common languages such as English, French, German, Italian, etc. As a result, only a small amount of learning objects and authoring tools have been developed for indigenous people considering the specific needs of their population. This paper introduces Multilingual–Tiny as a web authoring tool to support the virtual experience of indigenous students and teachers when they are creating learning objects in indigenous languages or in Spanish language, in particular, when they have to deal with the grammatical structures of Spanish. Multilingual–Tiny has a module based on the Case-based Reasoning technique to provide recommendations in real time when teachers and students write texts in Spanish. An experiment was performed in order to compare some local similarity functions to retrieve cases from the case library taking into account the grammatical structures. As a result we found the similarity function with the best performance

Saako historiasta selvää? Monikulttuuriset yläkoululaiset historian lähteillä historian taidot motiivien, seurauksien, historian tulkintojen ja lähteiden luotettavuuden arvioinneissa

The research assesses the skills of upper comprehensive school pupils in history. The focus is on locating personal motives, assessing wider reasons hidden in historical sources and evaluating source reliability. The research also questions how a wide use of multiple sources affects pupils’ holistic understanding of historical phenomena. The participants were a multicultural group of pupils. The origins of their cultures can be traced to the Balkan, the Middle East, Asia and Europe. The number of native Finnish speakers and pupils speaking Finnish as their second language was almost equal. The multicultural composition provides opportunities to assess how culturally responsive learning history from sources is. The intercultural approach to learning in a multicultural setting emphasizes equality as a precondition for learning. In order to set assignments at least to some extent match with all participants only those answers were taken into account which were produced by pupils who had studied history for a similar period of time in the Finnish comprehensive school system. Due to the small number of participants (41), the study avoids wide generalizations. Nevertheless, possible cultural blueprints in pupils’ way of thinking are noted. The first test examined the skills of pupils to find motives for emigration. The results showed that for 7th graders finding reasons is not a problematic task. However, the number of reasons noticed and justifications varied. In addition, the way the pupils explained their choices was a distinguishing factor. Some pupils interpreted source material making use of previous knowledge on the issue, while other pupils based their analysis solely on the text handed and did not try to add their own knowledge. Answers were divided into three categories: historical, explanatory and stating. Historical answers combined smoothly previously learned historical knowledge to one’s own source analysis; explanatory answers often ignored a wider frame, although they were effective when explaining e.g. historical concepts. The stating answers only noticed motives from the sources and made no attempts to explain them historically. Was the first test culturally responsive? All pupils representing different cultures tackled the first source exam successfully, but there were some signs of how historical concepts are understood in a slightly different way if the pupil’s personal history has no linkage to the concepts under scrutiny. The second test focused on the history of Native Americans. The test first required pupils to recognize whether short source extracts (5) were written by Indians or Caucasians. Based on what they had already learned from North American history, the pupils did not find it hard to distinguish between the sources. The analysis of multiphase causes and consequences of the disputes between Native Americans and white Americans caused dispersion among pupils. Using two historical sources and combining historical knowledge from both of them simultaneously was cumbersome for many. The explanations of consequences can be divided into two groups: the ones emphasizing short term consequences and those placing emphasis on long term consequences. The short term approach was mainly followed by boys in every group. The girls mainly paid attention to long term consequences. The result suggests that historical knowledge in sources is at least to some extent read through role and gender lenses. The third test required pupils to explain in their own words how the three sources given differed in their account of living conditions in Nazi Germany, which turned out to be demanding for many pupils. The pupils’ stronghold was rather the assessment of source reliability and accounts why the sources approached the same events differently. All participants wrote critical and justified comments on reliability and aspects that might have affected the content of the sources. The pupils felt that the main reasons that affected source reliability were the authors’ ethnic background, nationality and profession. The assessment showed that pupils were well aware that position in a historical situation has an impact on historical accounts, but in certain cases the victim’s account was seen as a historical truth. The account of events by a historian was chosen most often as the most reliable source, but it was often justified leniently with an indication to professionalism rather than with clear ideas of how historians conduct accounts based on sources. In brief, the last source test demonstrates that pupils have a strong idea that the ethnicity or nationalism determines how people explained events of the past. It is also an implication that pupils understand how historical knowledge is interpretative. The results also imply that history can be analyzed from a neutral perspective. One’s own membership in an ethnical or religious group does not automatically mean that a person’s cultural identity excludes historical explanations if something in them contradicts with his or her identity. The second method of extracting knowledge of pupils’ historical thinking was an essay analysis. The analysis shows that an analytical account of complicated political issues, which often include a great number of complicated political concepts, leads more likely to an inconsistent structure in the written work of pupils. The material also demonstrates that pupils have a strong tendency to take a critical stance when assessing history. Historical empathy in particular is shown if history somehow has a linkage to young people, children or minorities. Some topics can also awake strong feelings, especially among pupils with emigrant background, if there is a linkage between one’s own personal history and that of the school; and occasionally a student’s historical experience or thoughts replaced school history. Using sources during history lessons at school seems to have many advantages. It enhances the reasoning skills of pupils and their skills to assess the nature of historical knowledge. Thus one of the main aims and a great benefit of source work is to encourage pupils to express their own ideas and opinions. To conclude, when assessing the skills of adolescents in history - their work with sources, comments on history, historical knowledge and finally their historical thinking - one should be cautious and avoid cut off score evaluations. One purpose of pursuing history with sources is to encourage pupils to think independently, which is a useful tool for further identity construction. The idea that pupils have the right to conduct their own interpretations of history can be partially understood as part of a wider learning process, justification to study history comes from extrinsic reasons. The intrinsic reason is history itself; in order to understand history one should have a basic understanding of history as a specific domain of knowledge. Using sources does not mean that knowing history is of secondary importance. Only a balance between knowing the contextual history, understanding basic key concepts and working with sources is a solid base to improve pupils’ historical understanding.

Constituintes químicos de Sebastiania macrocarpa Muell. Arg. (Euphorbiaceae)

The chemical investigation of the methanolic extract of the aerial part of Sebastiania macrocarpa allowed the isolation of the mixture of steroids β-sitosterol and stigmasterol, gallic acid, and scopoletin. The hexane extract of the roots allowed the isolation of the triterpene lupeol and of the macrociclic diterpene (+)-tonantzitlolone. The structures of all compounds isolated were identified on the basis of their spectral data and by comparison of their spectral data with values described in the literature. This is the first report involving the chemical investigation of this species.

Effect of pulps fractionation on formation and strength properties of laboratory hand sheets

The objectives of the work were to study the effect of dewatering time varying on formation properties of papersheets, to determine the role of fines fraction in creation of paper with good formation and strength properties of papersheets, and also to study the effect of charge modification of fibers fractionations on formation properties of handsheets. The paper formation is one of the most important structural properties of paper. This property has effect on physical and optical characteristics of paper. In thi work the effect of formation on tensile strength was determined. The formation properties were analyzed by using the AMBERTEC Beta Formation Tester. The PAM addition as a f;locculant agent did some changes in the formation of paper. Paper sheets were also made from different furnishes of both birch and pine pulps. The fibers particles as a fines have great effect on drainability changes. Fines fraction played important role in papermaking. The two kinds of pulps (pine and birch pulps) were also used in this work for investigation of fines role. As it was expected the fines fraction gave positive effect on paper formation, but when fines fraction was added above initial fines content the formation of paper was deteriorated. The effect of paper formation on tensile strength was also determined. In many cases the poor formation of paper had negative effect on strength properties of paper..
