It was aimed to evaluate the influence of fungicides utilized in cucumber on the development of the aphid Aphis gossypii Glover under greenhouse conditions. The experimental design was completely randomized with four treatments and 45 replicates, being each plot consisting of a first instar nymph coming from an apterous female in early reproductive period. The fungicides utilized and their respective dosages at g i.a.L(-1) were 800 PM sulphur (1.6), 800 PM mancozeb (1.6) and 840 PM copper oxichloride (1.5). The control was made up of water only. The products did not influence the median time of life in each instar and the nymphal stage, being respectively 1 and 4 days. Copper oxychloride and mancozeb increased the median time of life in days and the total life cycle of the adult stage of this species.

La pieza-poema Morte e Vida severina Auto de natal pernambucano, de João Cabral de Melo Neto, publicada en 1956, es el principal objeto de este estudio, interaccionando con las obras O Cão sem plumas y O rio por la similitud temática entre ellas: el estudio sobre esas obras busca una lectura desvinculada del posicionamiento constructivista y metalingüístico que por tradición configura la obra cabralina, no por negar a la crítica literaria que da respaldo científico, pero con la pretensión de lanzar una nueva mirada dirigida para el concepto de barroco, materia ésta que implica la creación poética a partir de la segunda mitad del siglo XX. Por lo tanto, este trabajo presenta una propuesta de análisis de la poesía de João Cabral a partir del contexto neobarroco. Considerando, sobre todo, los aspectos similares a la temática del barroco, el enfoque recae sobre la influencia de la literatura ibérica por que pasa el poeta João Cabral, así como la temática sobre el conflicto existencial explorado en el texto Morte e Vida severina, y aún, los extractos de lenguaje con significación múltiple que presentan signos metonímicos y metafóricos.

João Cabral de Melo Neto n a jamais aimé les vers sentimentaux et prolixes venus de la tradition romantique. C est pour ça que son uvre a un discours objectif, rigoureusement elaboré e elle comporte certaines influences concretistes ça explique pourquoi l auteur est connu comme l ingénieur de la langage. En verité, le poète même dissait qu il était un homme froid et rationnel. La critique a assidument analysé la matière logique et le rigeuer formel de l uvre de Cabral de Melo. Pourtant, dans ce travail nous analysons les poèmes dont le sentiments humaines sont la mtière principal de l élaboration de l experiènce esthétique. La poèsie de João Cabral n est pas simple verbalisme formel, ni un uvre sens vie, car les objects concrètes et la langage objectif n empêchent pas qui le sujet décrit avec émotion les scènes presents dans les poèmes. Nous travaillons avec la hypothèse de que le poète a une attitude trop humaine quand il parle de l experience culturel et de l experience de la vie dans le Nord-est brésilien. Les unités témathiques de ce travail, pourtant, montrent la représentation du Nord-est dans la poèsie de João Cabral et examinent aussi le sentiment qu il sent par la memoire culturel de sa région. Parmi les aspects qui composent sa lyrique humaine nous citons la personification constant de les paysages du Nord-est le poète ne veux pas faire une décrition tophographique de la région parce que les places ont un valeuer sentimentel pour lui; au moyen d un discours erotique, Cabral represente les desirs et les intints humaines de sa terre; ensuite, il semble que le poète est enchanté et enveloppé avec certains elemets culturels de sa région, come l hamac, la littérature oral et la musique régional; la preoccupation avec la population explorée et la denonciation de la condition miserable dans le Nord-est brésilien confirment aussi la humanité présent dans son uvre; finalment, la récordation de l enfance et la nostalgie du temps passé sont, pour le poète, un possibilité qui peut aider dans la formation humaine de la population

This dissertation, entitled O Auto da Morte e da Vida: A escrita barroca de João Cabral de Melo Neto, has the aim of analising, interpreting, in a baroque perspective, Cabral s writing in the poem/play Morte e vida severina Auto de Natal Pernambucano, taking as basis the theories of Eugênio D´Ors, Severo Sarduy, Omar Calabrase, Lezama Lima, Afonso Ávila, Affonso Romano de Sant´Anna and others cited in the body of this work. During the analisys we feature confluences, relations, similarities, identification between the Baroque of the counter reformation and the modern Baroque or Neobaroque. We seek to comprehend the baroque which is new in the XX century and Cabral s poetry as an element of the contemporaneity, by updating the concept of the Baroque in the 1600s, when it is detected in its purest characteristic in human relation (the life of the Northwestern brazilian) through an intangible reality (the death). The Baroque as a cultural summary of a period of instability and transformation, with the power of dismantling an already established poetry. The fight between words and things, language and reality

The aim of this research is, starting from a Baroque reading, unfold the understanding of the poems by João Cabral de Melo Neto in the axis Pernambuco-Spain. From this perspective, the reading of poet s Obra Completa allows the appearance of two persons, one from Seville and other from the Brazilian countryside, whom curiously pulsate and reveal themselves from their homelands, Brazilian northeastern dry lands and Seville, to a labyrinthy meeting establishing a close and exciting relationship of cities apart but which mark a contiguous dialogue between both cultures. The theorical effort of this investigation permeates, approaches and contrasts the directions of, among others, Severo Sarduy (1999), Gilles Deleuze (2012) and Eugenio D Ors (unknown). Not traveling an anthropological bias, this study observes the Spanish space and the Brazilian northeastern dry lands space, joining the regional to the universal and analyzes the baroque game in the (re) construction of the both men s cultures. These elements fuse, approach and move away, causing a game of allusions to Pernambuco and Spain that show itself through a similar cultural bias and different at the same time. From this apprehension it is possible to understand the synthesis of the Brazilian arid northeast-Seville men as a update of seventeenth century Baroque coming from indexes that are shown over the particular written by João Cabral de Melo Neto, in the Iberian Baroque scenario and in the American one s

The stimulation of motor learning is an important component to a rehabilitation and type of practice used is de basic importance to Physiotherapy. The motor skills are the types more basic of behavior that subjects must acquire throughout its lives and observational learning one of forms for its acquisition. Objective: This study aimed to compare performance of patients post- stroke on test of recognition of activities of day life using self-controlled and externally determined practice. Intervention: Forty subjects had been evaluated, 20 stroke patients (the mean age was 57,9?}6,7 years, schooling 6,7?}3,09 years and time of injury 23,4?}17,2 months) and 20 health subjects (the mean age 55,4?}5,9 years and schooling 8?}3,7 years). All was evaluated about independence functional (FIM) and cognitive state (MMSE), and patients were also evaluated about neurologic state (NIHSS). Later, all realized a recognition of activities of day life test (drink water and speak to telephone) on self-controlled (PAUTO and CAUTO) and externally determined (P20 and C20) frequency. The stroke subjects also were examined for a three-dimensional system of kinematic analysis, when they have drink water. The statistic analysis was realized for chi-square and t Student tests. Results: This was not difference, about number of rightness, between groups of self-controlled and externally determined practice (p0,005), and also not between patients and control groups (p0,005). Patients mean velocity (PAUTO: 141,1mm/sec and P20: 141,6mm/sec) and peak velocity (PAUTO: 652,1mm/sec and P20: 598,6mm/sec) were reduced, as well as the angles reached for elbow (PAUTO: 66,60 and 124,40; P20: 66,30 and 128,50 extension e flexion respectively) regarding literature. Conclusions: The performance on recognition of activities of day life test was similar between on self-controlled and externally determined frequency, showing both technique may be used to stimulate motor learning on chronic patients after stroke

O desenvolvimento e a produção de frutos para consumo in natura dos cultivares de pepino 'Marketer IAC-2205', 'Palomar IAC-3050', 'Santee IAC-2441', 'Verde Paulistano IAC-1386' e 'Aodai 1-4321' foram estudados em duas épocas de semeadura, 5 de maio e 5 de dezembro, em Campinas, SP. Para todos os cultivares, as plantas semeadas em dezembro cresceram mais e desenvolveram-se com maior rapidez que as plantas semeadas em maio; entretanto, as produções das plantas semeadas em maio foram maiores e a qualidade de seus frutos foi superior. Tanto para as plantas semeadas em maio como para as semeadas em dezembro, 'Santee' apresentou produções baixas e frutos de má qualidade. 'Aodai' foi o cultivar mais produtivo e seus frutos foram os de melhor qualidade. As produções dos demais cultivares foram equivalentes. 'Verde Paulistano' apresentou a produção mais tardia. 0 comportamento de 'Marketer' foi pouco afetado pelas variações ambientais. As maiores produções de todos os cultivares, nas duas é poças, foram obtidas entre a terceira e a penúltima colheitas. Foram encontradas correlações positivas entre a produção de cada colheita e a produção total, entre a produção total e a produção comerciável, entre o número de frutos e seu peso, entre produção e a altura da planta e entre produção e número de ramos laterais da planta. A relação entre produções comerciável e total e o peso médio dos frutos diminuíram no final do ciclo das plantas.

Com o objetivo de estudar o efeito de herbicidas aplicados em pré e pós-emergência, isolados e em combinações nas épocas seca e úmida, para o controle de melão-de-são-caetano (Momordica charantia) em área de cana-soca, desenvolveu-se um experimento no período de junho de 2007 a julho de 2008, na Fazenda Gabriela, no município de Bebedouro (SP). O delineamento experimental foi o de blocos ao acaso, com quatro repetições, em esquema de parcela subdividida. Nas parcelas foram estudados quatro tratamentos de herbicidas: imazapic (0,147 kg ha-1) e amicarbazone (1,4 kg ha-1), aplicados uma semana após a colheita da cana; clomazone mais hexazinone (0,8 kg ha-1 + 0,2 kg ha-1) e amicarbazone (1,4 kg ha-1), aplicados em agosto, aos 63 dias após a colheita da cana, pulverizados na época seca, além de tratamento sem aplicação. Nas subparcelas foram testadas as aplicações em pós-emergência de quatro tratamentos de herbicidas: mesotrione (0,192 kg ha-1), amicarbazone (1,4 kg ha-1), mesotrione mais amicarbazone (0,096 kg ha-1+ 0,7 kg ha-1) e 2,4-D (1,005 kg ha-1), na época úmida e a manutenção de tratamento sem herbicida. Para o controle de melão-de-são-caetano a aplicação de herbicidas na época úmida (período de chuvas) é obrigatória e desnecessária na época seca. Os herbicidas mesotrione e amicarbazone, isolados ou em mistura, aplicados na época úmida são eficazes no controle em pós-emergência das plantas e na inibição de novos fluxos de emergência de melão-de-são-caetano na época úmida.

O presente trabalho foi conduzido com o objetivo de se estudar 3 doses de N e 3 doses de K2O, combinadas entre si e aplicadas em cobertura aos 15, 30 e 45 dias após a emergência das plântulas, na eficiência do uso da água e na qualidade de frutos de melão. Utilizou-se um Podzólico Vermelho Escuro, eutrófíco, textura média/argilosa, do município de Ilha Solteira(SP). O experimento foi implantado no ano de 1991 fazendo-se uso dos cultivares Valenciano Amarelo e Eldorado 300, em espaçamento de 2,0m entre linhas e 0,75m entre covas. A cultura foi conduzida sem capação e desbrota e os tratamentos fítossanitários procedidos de acordo com a necessidade. Pelos resultados obtidos verificou-se que o N ou o K2O influenciaram alguns parâmetros no cultivar Eldorado 300: peso da casca, peso de sementes com mucilagem e acidez titulável, além do rendimento de polpa no cultivar Valenciano Amarelo.

Cucumis anguria present dark germinating seeds at 25 degrees C. Seeds without the tegument are photosensitive germinating better in darkness than under continuous white light. However, pre-incubation at 40 degrees C for 48 hours allows the seeds to germinate under continuous white light and the incubation of naked seeds at -0.6MPa restored the light inhibition of seed germination. Our results suggest that the tegument interact with the phytochrome in the control of seed germination in part of the population of seed of C. anguria.

Shikimate dehydrogenase (SDH, EC 1.1.1.25) extracted from cucumber pulp (Cucumis sativus L.) was purified 7-fold by precipitation with ammonium sulfate and elution from columns of Sephadex G-25, DEAE-cellulose, and hydroxyapatite. Two activity bands were detected on polyacrylamide gel electrophoresis at the last purification step. pH optimum was 8.7, and molecular weight of 45 000 was estimated on a Sephadex G-100 column. SDH was inhibited competitively by protocatechuic acid with a K(i) value of 2 x 10-4 M. K(m) values of 6 x 10-5 and 1 x 10-5 M were determined for shikimic acid and NADP+, respectively. The enzyme was completely inhibited by HgCl2 and p-(chloromercuri)benzoate (PCMB). NaCl and KCl showed partial protection against inhibition by PCMB. Heat inactivation between 50 and 55-degrees-C was biphasic, and the enzyme was completely inactivated after 10 min at 60-degrees-C. Incubation of SDH with either NADP+ or shikimic acid protected the enzyme against heat inactivation.

In negatively photoblastic seeds of Cucumis anguria L. the scarification of micropyle overcame the inhibitory effect of white light , although far-red radiation inhibited the germination in both intact and scarified seeds. The moistened testa powder transmitted more far-red than red radiation. Thus the testa could act as a filter of radiation and maintain a high far-red/red ratio at the photosensitive site of the embryo, which must be localized near the micropyle. © 1988 Academia.
