Resumo: Os vírus pertencentes ao gênero Begomovirus da família Geminiviridae são transmitidos pela mosca-branca Bemisia tabaci Gennadius, atualmente constituem um dos problemas fitossanitários mais sérios em diversas culturas. A mosca-branca encontra-se disseminada em todas as principais regiões produtoras de hortaliças do Brasil. No estado de São Paulo, em 2005, plantas de pimentão mostrando sintomas de deformação dos frutos, folhas e mosaico foliar, apresentaram-se infectadas por begomovírus. Até então, no Brasil, a infecção de pimentão por vírus deste gênero havia sido verificada apenas nos estados de Pernambuco e Bahia, no ano de 1997. Amostras de plantas de pimentão foram coletadas nos campos de produção localizados nos municípios de Paranapanema, Piraju, Alvinlândia, Ubirajara, Elias Fausto, Mogi Guaçu, Paulínia e Botucatu, no período de novembro de 2004 a maio de 2006, com finalidade de detecção e verificar a variabilidade genética dos begomovírus infectando esta cultura. A detecção de begomovírus foi realizada por meio de PCR com oligonucleotídeos universais e seqüenciamento de parte da região codificadora para a proteína capsidial. Do total de 228 plantas coletadas, foram encontradas 30 amostras positivas de begomovírus, sendo que seqüências de 23 isolados apresentaram uma identidade de nucleotídeos de 98 a 100% com o Tomato severe rugose virus (ToSRV) e dois isolados, um proveniente da região de Alvinlândia e outro de Mogi Guaçu, apresentaram maior identidade (98 e 95% respectivamente) com a provável espécie Tomato yellow vein streak virus (ToYVSV). O DNA-A do isolado ToSRV[PJU] coletado de pimentão Lilac da região de Pirajú apresentou identidade de nucleotídeos de 99% com outro isolado de ToSRV (DQ207749) proveniente de pimenta e 97% com um isolado de ToSRV (AY029750) proveniente de tomate...

The whitefly is disseminated throughout the country. In São Paulo State, 2005, pepper plants showing fruits deformations, and mosaic on the leaves were infected by begomovirus. Until then in Brazil, the infection of begomovirus in pepper was only reported in 1997, in Pernambuco and Bahia States. Pepper plants were collected in Paranapanema, Piraju, Alvinlândia, Ubirajara, Elias Fausto, Mogi Guaçu, Paulínia and Botucatu, in the period of November of 2004 to May of 2006, with the aim to study the genetic variability of the begomovirus infecting this culture. The begomovirus were detected by PCR using universal oligonucleotídeos and the coat protein region was sequenced. On the total of 228 samples, they were found 30 positive samples of begomovírus, and sequences of 23 isolated presented nucleotides identies of 98 to 100% with Tomato severe rugose virus (ToSRV), while two isolates, one of Alvinlândia and another of Mogi Guaçu, showed identity highest nucleotide (98 and 95% respectively) with the tentative species Tomato yellow vein streak virus (ToYVSV). The nucleotide sequence of the DNA-A of ToSRV[PJU] from pepper cv. Lilac of Pirajú has 99% nucleotide identies with other isolate of ToSRV (DQ207749) collected from pepper and 97% with an isolate of ToSRV (AY029750) from tomato. The sequence of the DNA-B revealed identity of 98% with the DNA-B of ToRMV (AF291706) from Triângulo Mineiro, Minas Gerais and 95% with ToSRV (AY029751). Sap-transmission was verified for Nicandra physaloides and pepper ‘Magda' using infected N. benthamiana as source. By whitefly the virus was transmitted to Lycopersicum esculentum...

This work explores the relationship between time, temporality, and power by utilizing interactions between Jesuit missionaries and the Ming and Qing governments of late imperial China as a case study. It outlines the complex relationship between knowledge of celestial mechanics, methods of measuring the passage of time, and the tightly controlled circumstances in which that knowledge was allowed to operate. Just as the Chinese courts exercised authority over time and the heavens, so too had the Catholic Church in Europe. So as messengers of God’s authority, the Jesuits identified the importance of astronomical and temporal authority in Chinese culture and sought to convey the supremacy of Christianity through their mastery of the stars and negotiate positions of power within both imperial governments.

This essay examines commitment and abandonment structured as two binary opposites informing For Whom the Bell Tolls. The intention behind this structuring is to highlight Hemingway’s message of the novel, set forth by the epigraph by Donne; everyone is part of mankind and every death diminishes everyone equally. The consistent structuring of characters can be seen by the fact that everyone who is committed, loyal and honest is punished while the reverse is true for people who abandon, desert and betray. The one exception to this is Pilar who, because of the role as a liberated woman given to her by Hemingway, is not included in this general categorization.

Cette recherche, caractérisée par l'histoire du capitalisme (du fordisme au post-fordisme), par l'histoire de Bell Canada (de la téléphonie, de la télévision et de l'Internet) et par l'histoire socioculturelle du Québec (les valeurs, les comportements et les usages à l'œuvre entre 1970 et 2000), ouvre la voie à une vision novatrice des représentations sociales observées au sein des publicités sur les technologies de l'information et de la communication de Bell Canada entre 1970 et 2000. Pour déceler puis révéler cette vision, une perspective historique est adoptée dans cette recherche, ce qui permet de mieux comprendre la société au sein de laquelle les publicités diffusées entre 1970 et 2000 étaient conçues. Mais, pour comprendre la nature même du phénomène publicitaire, une perspective théorique a également été mise en place, ce qui ultimement permet de saisir comment un tel phénomène peut engendrer des représentations sociales du passé, du présent ou du futur de la société qui les abrite. Est-il possible que les publicités portant sur les TIC de Bell Canada ne reflètent pas que la réalité du moment et qu'elles intègrent d'autres éléments (de fiction, du passé, du présent comme du futur) pour modifier (par les valeurs, les comportements et les usages notamment) la réalité à venir? Pour répondre à cette question, il a fallu faire appel, dans le cadre d'une approche de type anthropologique, à l'analyse de contenu publicitaire. Cela dit, avant d'en arriver à l'étape de l'analyse, un maximum de publicités a dû être récupéré aux archives de Bell Canada, au Centre d'Archives Publicitaires du Québec, chez Cossette Communication Marketing ainsi que sur le site d'échanges de vidéos YouTube pour constituer l'échantillon principal. Une fois cela fait, l'échantillon principal d'une centaine de publicités a été restreint à 24 publicités choisies en fonction des technologies qu'elles promeuvent. Neuf publicités au final ont été sélectionnées (trois par décennie à l'étude) pour déceler les éléments, visuels ou discursifs, représentant ou anticipant la réalité québécoise. Une fois l'analyse entamée, il a rapidement été possible de constater que chaque publicité renfermait en son sein des éléments représentationnels du passé, du présent et du futur et que toutes convergeaient en un même point (le gain) pour soutenir le discours socioéconomique de la publicité. La confluence observée ne modifie en rien la problématique, mais elle explique en partie pourquoi les représentations du passé, du présent ou du futur sont parfois difficilement observables indépendamment les unes des autres. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Publicité, représentation, anticipation, Bell Canada, TIC, société, culture, économie, Québec, anthropologie, analyse de contenu.

The collision of impulsive gravitational waves, electromagnetic plane waves with collinear polarization and, especially, plane fronted parallel waves (pp waves) are considered. The solution of axisymmetric pp waves is reviewed and the structures of the resulting space-times are investigated with the help of curvature invariants.
