VANTAGENS E DESVANTAGENS ACERCA DA TRADU O NO ENSINO DE LíNGUA INGLESA
Lilian Agg Garcia,Janaína Carvalho,Joana Quéren Frujuelle Kehdi,Claudia Lemos Baumrucker
Fólio : Revista de Letras , 2011,
Abstract: This article aims to present reflections about the possible advantages and disadvantages of the use of translation in the English classes in two public schools from Santa Catarina State highlighting some situations in which translating would be justifiable over the English Language learning and teaching process. Two study cases were analyzed and they illustrated the effects provided by some moderate and exaggerated uses of translation from English into Portuguese during such classes. The survey attempts to describe the way two English teachers from two state secondary schools in Itapema and Joinville, Santa Catarina, made use of translation over their lessons as well as how successful their students’ learning was. The results of it show that the reasonable use of translation might be helpful unless its aims are clear and tend to develop a better learning of the students.
Constru??es identitárias: ser leitor e alfabetizador de jovens e adultos
Vóvio, Claudia Lemos;
Linguagem em (Dis)curso , 2008, DOI: 10.1590/S1518-76322008000300003
Abstract: this article focuses on the relations between language and the construction of reading identities by non-formally trained teachers of adults and young adults in basic literacy programs. results from a phd research focusing on the study of these agents′ literacy process are presented. we asked the subjects what type of readers they were, in order to learn the meanings they attributed to reading, with the purpose of contributing to programs geared to their professionalizing and community needs. the data analysis, from a linguistic-enunciative and discursive perspective, revealed differences from previous research results involving professionally trained literacy teachers, i.e., the assertive and positive ways in which the subjects produced their self-images as readers and, consequently, as literacy teachers. we observed a self-legitimation movement through discursive operations which focus on the exaltation of personal characteristics, on the reference to cultural objects taken as legitimate, and on the familiarity with new cultural practices.
Constru es identitárias: ser leitor e alfabetizador de jovens e adultos

Linguagem em (Dis)curso , 2008,
Abstract: Este artigo focaliza as rela es entre linguagem e constru o de identidades leitoras por alfabetizadores de jovens e adultos. Apresenta resultados de uma pesquisa de doutorado que teve como foco o letramento desses agentes. Ao interpelar os discursos desses agentes sobre si mesmos e aceder aos sentidos atribuídos à leitura, pretende-se contribuir para o delineamento de processos de forma o. A análise, numa perspectiva lingüístico-enunciativo-discursiva, revelou um aspecto distintivo frente aos resultados de pesquisas prévias com profissionais docentes: a forma assertiva e positivada com que produziram imagens de si, como leitores e, conseqüentemente, como alfabetizadores. Nessa constru o, observa-se ainda um movimento de autolegitima o por meio de opera es discursivas que têm como foco a exalta o de propriedades pessoais, a referência a objetos culturais tomados como legítimos e o transito por novas práticas culturais.
Mammary mechanisms for lactoferrin: interactions with IGFBP-3.
Baumrucker C.R.
Biotechnologie, Agronomie, Société et Environnement , 2000,
Abstract: Lactoferrin (Lf) is an iron-binding protein found in high concentrations in mammary secretions but synthesized by many tissues. Bovine mammary tissue secretes microg/ml mass of Lf in milk, but during involution and prepartum periods, 20-80 mg per ml concentrations may be observed. While a number of functions have been ascribed to lactoterrin, only the antimicrobial and lymphocyte interactions have compelling experimental evidence of support. We report a new finding that lactoferrin binds to insulin-like growth factor binding protein-3 (IGFBP-3) and not to other mammary secreted IGFBPs (IGFBP-2, -4. and -5). Furthermore, bovine Lf(bLf) is found associated with membranes of mammary cells. We demonstrate that bovine Lf competes with IGF for binding to IGFBP-3 with ED50 competition of 3 microg per ml and displacement of 1 mg per ml to monomeric bLf. The tetrameric form that is favored by high concentrations of Lf and calcium, does not appear to bind IGFBP-3. Both IGFBP-3 and Lf have nuclear localization sequences that are reported to he key components of nuclear localization of proteins. We demonstrate that extracellular IGFBP-3 binds to membrane Lf and that Lf is the key to the entry of IGFBP-3 to mammary cellular nucleus. Additionally, we have shown that the internalization of Lf requires the presence of retinoids that also induces both IGFBP-3 and Lf synthesis in primary cultures of bovine mammary epithelial cells. We hypothesize a new role for Lf in the regulation and integration into the IGF System.
Thermodynamics of Reissner-Nordstrom-anti-de Sitter black holes in the grand canonical ensemble
Claudia Pe?a,Jose' P. S. Lemos
Physics , 1998, DOI: 10.1103/PhysRevD.59.124007
Abstract: The thermodynamical properties of the Reissner-Nordstr\"om-anti-de Sitter black hole in the grand canonical ensemble are investigated using York's formalism. The black hole is enclosed in a cavity with finite radius where the temperature and electrostatic potential are fixed. The boundary conditions allow us to compute the relevant thermodynamical quantities, e.g. thermal energy, entropy and charge. The stability conditions imply that there are thermodynamically stable black hole solutions, under certain conditions. Instantons with negative heat capacity are also found.
Dirac's theorem on simplicial matroids
Raul Cordovil,Manoel Lemos,Claudia Linhares Sales
Mathematics , 2006,
Abstract: We introduce the notion of k-hyperclique complexes, i.e., the largest simplicial complexes on the set [n] with a fixed k-skeleton. These simplicial complexes are a higher-dimensional analogue of clique (or flag) complexes (case k=2) and they are a rich new class of simplicial complexes. We show that Dirac's theorem on chordal graphs has a higher-dimensional analogue in which graphs and clique complexes get replaced, respectively, by simplicial matroids and k-hyperclique complexes. We prove also a higher-dimensional analogue of Stanley's reformulation of Dirac's theorem on chordal graphs.
Perspectivas para o currículo da Educa o de Jovens e Adultos: dinamicas entre os conhecimentos do cotidiano e da ciência
Claudia Barcelos de Moura Abreu,Claudia Lemos Vóvio
Educa??o : Revista do Centro de Educa??o UFSM , 2010, DOI: 10.5902/198464441374
Abstract: Este artigo tem por objetivo apresentar alguns dos desafios na organiza o de currículos da escolariza o de pessoas jovens e adultas, de modo a se cumprir as metas educacionais postuladas para essa modalidade de ensino e efetivar o direito à educa o para todos os cidad os. Interessa investigar, por meio de análise documental, como um conjunto de princípios norteadores que emergiram do campo da educa o popular e que indicam um certo acúmulo de conhecimentos para a produ o de currículos na área pode ser observado, tomando como referência empírica as bases de um currículo voltado à educa o de jovens e adultos (EJA). Igualmente, pretende-se verificar como se apresentam, no documento, as rela es entre conhecimentos do cotidiano e os conhecimentos científicos. Os resultados obtidos por esta análise mostram que há uma apropria o das principais categorias do campo da EJA para pensar o novo currículo, mas é possível perceber que a rela o entre conhecimentos cotidianos e científicos precisa ainda ser trabalhada de forma mais rigorosa, considerando a fun o social da escola. Palavras-chave: Educa o de jovens e adultos. Escolariza o. Organiza o curricular.
Leaf life span and nitrogen content in semideciduous forest tree species (Croton priscus and Hymenaea courbaril)
Haddad, Claudia Regina Baptista;Lemos, Damiani Pereira;Mazzafera, Paulo;
Scientia Agricola , 2004, DOI: 10.1590/S0103-90162004000400018
Abstract: in comparison to deciduous species, evergreen plants have lower leaf nutrient contents and higher leaf life span, important mechanisms for nutrient economy, allowing the colonization of low fertility soils. strategies to conserve nitrogen in two semideciduous tropical forest tree species, with different leaf life spans were analyzed. the hypothesis was the fact that the two species would present different nitrogen conservation mechanisms in relation to chemical (total nitrogen, protein, chlorophyll, and proteolytic activity), functional (leaf life span, n-use efficiency, and n-resorption efficiency), morphological (specific leaf mass) leaf characteristics, and total nitrogen in the soil. hymenaea courbaril l. presented lower nitrogen compounds in leaves, longer leaf life span, higher n-use efficiency, and higher specific leaf mass, while absorbing proportionally less nitrogen from the soil than croton priscus croizat. these characteristics can contribute for a better nitrogen economy strategy of h. courbaril. no relationship was found between leaf life span and n resorption efficiency, nor between leaf life span, protease activity and nitrogen mobilization. the electrophoretic profiles of proteolytic enzymes in young leaves of the two species presented more bands with enzymatic activity than other kinds of leaves.
Thermodynamics of toroidal black holes
Claudia S. Pe?a,José P. S. Lemos
Physics , 1998, DOI: 10.1063/1.533378
Abstract: The thermodynamical properties of toroidal black holes in the grand canonical ensemble are investigated using York's formalism. The black hole is enclosed in a cavity with finite radius where the temperature and electrostatic potential are fixed. The boundary conditions allow one to compute the relevant thermodynamical quantities, e.g. thermal energy, entropy and specific heat. This black hole is thermodynamically stable and dominates the grand partition function. This means that there is no phase transition, as the one encountered for spherical black holes.
Orthotophic Liver Transplantation in Giant Hepatic Hemangioma: A Case Report and Literature Review  [PDF]
Jessica Casella, Carla Lemos Gottgroy, Carlos Rocha Maia, Felipe Pedreira Tavares de Mello, Samanta Teixeira Basto, Claudia Cristina Tavares de Souza, Eduardo de Souza Martins Fernandes
Open Journal of Organ Transplant Surgery (OJOTS) , 2013, DOI: 10.4236/ojots.2013.33009
Abstract: Hemangioma is the most common benign tumor affecting the liver in 7% of general population. One of the rare presentations of this pathology is gigantic liver hemangioma, reported in the literature as anecdotal cases. In selected cases, liver transplantation has been a therapeutic option. We herein describe a case of massive liver hemangioma which was submitted to liver transplant, and the main indication for liver transplant in this case was a severe psychosocial impact of the disease in the patient’s life, altogether with Kasabach-Merritt syndrome and abdominal discomfort.
