Abstract: The aim of the current manuscript was to analyze the effect of application of Promalina(GA4,7 + BA) on yield parameters of apple crop in a trial carried out at Porto Amazonas, Southern region of Paraná State. The trees were three year old grafted onto Maruba rootstock spaced 4 m x 1.4 m. The variables evaluated were length, fresh mass and diameters of the fruit, soluble solids (SS) and flesh firmness. For all the variables no significant changes had been observed. The lack of weight increase and without changes in fruit shape do not allow to validate Promalin use for Parana Central Southern conditions. Com o objetivo de avaliar o efeito da aplica o de Promalina(GA4,7 + BA) sobre variáveis de rendimento em macieira conduziu-se um experimento no município de Porto Amazonas, na regi o sul do Paraná, na safra 2003/04. A área experimental constituiu-se da cultivar Gala, com três anos de idade, enxertada em Maruba com filtro M9 no espa amento 4 m x 1,4 m. Foram avaliadas as variáveis: comprimento, massa fresca e diametro do fruto, sólido solúveis (SS) e firmeza da polpa. Para as variáveis estudadas n o foram observadas varia es significativas. A falta de ganho de peso e de modifica o da forma do fruto n o permite validar o uso da Promalina para as condi es do centro sul do Paraná.

Abstract: The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes and plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable of colonizing intercellular spaces of grasses such as rice and sugar cane. The genome of H. seropedicae strain SmR1 was sequenced and annotated by The Paraná State Genome Programme—GENOPAR. The genome is composed of a circular chromosome of 5,513,887 bp and contains a total of 4,804 genes. The genome sequence revealed that H. seropedicae is a highly versatile microorganism with capacity to metabolize a wide range of carbon and nitrogen sources and with possession of four distinct terminal oxidases. The genome contains a multitude of protein secretion systems, including type I, type II, type III, type V, and type VI secretion systems, and type IV pili, suggesting a high potential to interact with host plants. H. seropedicae is able to synthesize indole acetic acid as reflected by the four IAA biosynthetic pathways present. A gene coding for ACC deaminase, which may be involved in modulating the associated plant ethylene-signaling pathway, is also present. Genes for hemagglutinins/hemolysins/adhesins were found and may play a role in plant cell surface adhesion. These features may endow H. seropedicae with the ability to establish an endophytic life-style in a large number of plant species.

Abstract: O comércio de caqui fresco resulta em grande quantidade de frutos n oclassificados. Assim, considerando também que a desidrata o prolonga a vida-de-prateleira de alimentos perecíveis, a pesquisa se prop s a fazer uma contribui o para o desenvolvimento do processo de fabrica o de passa a partir de frutos de caqui ‘Fuyu’. Foi utilizado um secador contendo circula o for ada de ar e cinco bandejas. O fruto descascado foi fatiado em quatro formas diferentes: fatias em metades, de corte transversal; fatias em , de cortes longitudinais; fatias em , de corte longitudinal seguido de corte transversal; fatias em 1/8, de dois cortes longitudinais seguidos de transversais. A condi o de secagem que aplicou temperatura de 80°C por 1h seguida de 60°C por cerca de 23h produziu passas de caqui ‘Fuyu’ com a melhor aparência. A forma da fatia passa que teve a preferência dosprovadores foi aquela em que o fruto foi cortado em oito fatias (fatias de 1/8). As passas de caqui ‘Fuyu’ contendo umidades residuais baixas, 19,7 e 27,4%, foram apreciadas, quanto ao paladar, igualmente pelos provadores. Os frutos de caqui proporcionaram, em peso, 16,7 e 18,1% de produtos em passas e perdas estimadas em 25,5%. Os resultados indicaram que a passa de caqui ‘Fuyu’ constitui-se numa excelente oferta de fruta desidratada. Because kakis are usually sold fresh, this results in a high number of fruits that do not meet the marketing standard. Thus, considering that dehydration extends the shelf life of perishable foods, this research was aimed at providing a contribution for the development of a product referred to as dehydrated ‘Fuyu’ kaki. A forced air circulation dehydrator was used, equipped with five trays. The peeled fruit was sliced in four different ways: sliced into halves, transversally; sliced into quarters, longitudinally; sliced into quarters, once longitudinally and once transversally; sliced into eighths, by cutting twice longitudinally and then once transversally.The drying conditions adjusted at 80°C for 1h, followed by 60°C for 23h resulted in a dehydrated ‘Fuyu’ kaki of better pleasant in aspect. The slicing method preferred by the samplers was that in which the fruit was sliced into eight slices (eighths). The dehydrated‘Fuyu’ kaki, at low residual moistures of 19.7 or 27.4%, were pleasant in aspect and palate, and had good acceptance by samplers. The kaki fruit yielded 16.7 and 18.1% in weight of dehydrated products. Fruit losses during preparation into slices were estimated at 25.5%. The results demonstrated that the dehydrated ‘Fuyu’ kaki product is an excellent
Do patológico ao cultural na surdez: para além de um e de outro ou para uma reflex?o crítica dos paradigmas

Trabalhos em Linguística Aplicada , 2008, DOI: 10.1590/S0103-18132008000100013
Abstract: this paper aims at making a discussion regarding two main ideological paradigms in deaf education, namely, pathological and cultural. to accomplish that, i point out the importance of discussing concepts such hearing impaired, deaf-mute, and mute in order to deconstruct the negative connotations these names imply in the social representation and cultural identity of deaf individuals. in addition, it will be shown how these views are present in social environments, specially in the classroom interaction between deaf teachers and hearing students. the data is generated and analyzed through ethnographic perspectives in brazilian sign language teaching contexts.
Construindo e legitimando a identidade intérprete e as atividades de interpreta o: reflex es feitas em aulas de Libras para ouvintes
Audrei Gesser
Tradu??o & Comunica??o : Revista Brasileira de Tradutores , 2011,
Abstract: Este artigo tem como objetivo descrever a intera o entre um professor surdo e seus alunos ouvintes, participantes de aulas de Libras, cujos registros foram gerados (MASON, 1997) e analisados a partir de ferramentas oriundas de pesquisa de cunho etnográfico (ELLEN, 1984; ELY et alii, 1991; HAMMERSLEY; ATKINSON, 1983). Orientada também por princípios teóricos da Sociolingüística Interacional, que incorpora a compreens o que os participantes envolvidos têm dos significados locais da intera o em curso, aponto como as identidades ouvintes e surdas s o manifestadas na e através da linguagem no encontro face a face (GOFFMAN, 1981, 2002; GUMPERZ, 1982a/b, JACOB; OCHS, 1995; SCHIFFRIN, 1996). No decorrer das aulas, fica saliente em vários momentos da intera o a necessidade de se legitimar a identidade-intérprete. Isto ocorre quando o grupo percebe que há alguém que se comunica um pouco melhor em sinais com o professor. A análise revela que diversos significados est o em jogo durante esta constru o, e que tanto a figura do intérprete como as atividades de interpreta o clamadas e negociadas pelo grupo s o fluidas, e quando emergem em linhas definidas elas est o atreladas ao momento, ao objetivo da intera o e aos interesses de cada um.
