Otimização de protocolo para análise de AFLP em Lolium multiflorum Lam.

ESTABELECIMENTO DE METODOLOGIA PARA ANÁLISE MOLECULAR DE AZEVÉM ANUAL COM MARCADORES AFLP. O uso de marcadores moleculares no manejo de bancos de germoplasma tem sido cada vez mais expressivo. Entre os diferentes tipos de marcadores moleculares, o AFLP, Amplified Fragment Length Polymorphism, apresenta algumas vantagens para uso na caracterização de recursos genéticos, como a detecção de grande número de bandas informativas por reação, com ampla cobertura do genoma e considerável reprodutibilidade, além de não necessitar de dados de seqüenciamento prévio da espécie para a construção de primers. Embora a análise de AFLP seja freqüentemente utilizada em estudos de variabilidade genética em diferentes espécies, o uso da técnica em Lolium multiflorum ainda é incipiente. Com a finalidade de estabelecer um protocolo para o emprego da técnica de AFLP em azevém anual foi conduzido este trabalho. Foram avaliadas as concentrações iniciais de DNA genômico de 100 e 250 ng, a digestão do DNA com 1,25 e 1U das enzimas EcoRI e MSe, e os respectivos tempos de reação de digestão: 3, 6 e 12 horas. Também foram avaliadas quatro concentrações da solução resultante da ligação dos adaptadores: solução sem diluição; diluída 1:5; 1:10 e 1:20 e duas diluições após a reação de pré-amplificação, de 1:25 e 1:50. Como resultado, foi estabelecido como melhor protocolo, no qual foi obtido um maior número e qualidade de fragmentos, o que utiliza a concentração inicial de DNA genômico de 100 ng, num volume final de reação de digestão 10 ?l, com 1U de cada enzima EcoRI e MseI e tempo de reação de 12h a 37°C, com reação de ligação de adaptadores realizada com a adição da solução de ligação de adaptadores, do Kit AFLP? Analysis System I (InvitroGen Life Technologies, Carlsbad, Calif., USA), e 0,4 U de T4 DNA ligase em um volume final de 10?l, por 2h a 20°C. Após a ligação de adaptadores a diluição deverá ser de 1:5. A reação de pré-amplificação deverá ocorrer a partir de 1?l desta última solução (diluída 1:5), 1,0 X PCR buffer com Mg Plus [Tris-HCl (pH 7.6) 20 mM, MgCl2 1,5 mM, KCl 50 mM], BSA 0,003% e 1 U de Taq DNA polimerase, completando com mix de pré-amplificação do Kit AFLP? Analysis System I até alcançar o volume final de 11?l. O produto da pré-amplificação deverá ser diluído 1:25 antes de ser procedida à amplificação seletiva, a qual deve ser realizada utilizando 2,5 ?l da solução de DNA pré-amplificado (diluído 1:25), 1 X PCR buffer com Mg Plus [Tris-HCl (pH 8,4) 20 mM, MgCl2 1,5 mM, KCl 50 mM], BSA (0,003%), 1 U de Taq DNA polimerase, 10 ng de primer EcoRI, 1,5 ng de primer MseI, 0,4mM de DNTps e H2O MilliQ? até completar o volume final de 10?l. Com este protocolo uma única combinação de primers permitiu identificar 58 bandas polimórficas na análise de duas populações de azevém anual.

Fine-Grained Layered Multicast

Traditional approaches to receiver-driven layered multicast have advocated the benefits of cumulative layering, which can enable coarse-grained congestion control that complies with TCP-friendliness equations over large time scales. In this paper, we quantify the costs and benefits of using non-cumulative layering and present a new, scalable multicast congestion control scheme which provides a fine-grained approximation to the behavior of TCP additive increase/multiplicative decrease (AIMD). In contrast to the conventional wisdom, we demonstrate that fine-grained rate adjustment can be achieved with only modest increases in the number of layers and aggregate bandwidth consumption, while using only a small constant number of control messages to perform either additive increase or multiplicative decrease.

IS capability assessment - the MIND canvas

With the increasing ubiquity and growing pervasiveness of Information Systems (IS) in todays’ organisations, one of the capabilities of essential value to an organisation is its IS/IT (henceforth IS) capability. However, despite this increasing importance of the IS capability, research has barely focused on providing a measure for assessing the IT capability of an organization. In overview, IS capability has contributed significantly in understanding how information technology remains a valuable component of any modern day firm (Bharadwaj 2000, Santhanam and Hartono 2003). While these prior research focus in itself is of value in establishing the importance of IS capability, this current study posits that this research area is attaining maturity and it is about time we extend this stream to provide a measure for assessing and evaluating the IS capability that defines an organization. To borrow a quote from Peter Drucker - “if it can be measured; it can be improved”.

STUDIES AND PERFORMANCES OF TRANSCRIPTIONS FOR CELLO FROM THE VIOLIN REPERTOIRE

The potential of the violoncello as a solo instrument was recognized and supported by cellists such as Luigi Boccherini (1743-1805), Luis Duport (1749-1819), Auguste Franchomme (1808-1884), and Alfredo Piatti (1822-1901). These pioneers composed technically demanding etudes, exercises, and caprices for the cello that were comparable to those already present in the violin literature. Even so, in the late nineteenth century and early twentieth century, considerably fewer substantial works were brought forth for the cello as compared with the violin. Consequently, many cellists such as Luigi Silva (1903-1961), Gregor Piatigorsky (1903-1976), Pierre Fournier (1906-1986), and Janos Starker (b. 1924) selected notable pieces from the violin repertoire and transcribed these for the cello. Some composers themselves actually adapted for the cello their own works originally written for the violin. Johannes Brahms with his Violin Sonata Op. 78, Igor Stravinsky with his Suite Italienne, and Béla Bartók with his First Rhapsody all belong to this category. Adaptations such as these further raised awareness among composers and performers of the possibilities of the cello as an independent and expressive instrument. Thus, many composers from the early 1900s to the present were encouraged to write increasing numbers of more soloistic and demanding works for cello. Herein, I explore the repertoire of cello transcriptions in order to analyze the differences between the original and transcribed versions and the challenges found therein. The performer may attempt to recreate the effect originally intended for the violin or, more daringly, may strive to search for alternate presentations of the music more suitable and expressive of the cello's own character. The project includes two recitals of the following transcribed works presented at the University of Maryland College Park, School of Music: Sonata in A by César Franck, transcribed by Jules Delsart, Variations on a Theme from Rossini by Nicolo Paganini, transcribed by Fournier, Suite Italienne by Igor Stravinsky, transcribed with the help of Piatigorsky, Sonatina Op. 137, No. 1 by Franz Schubert, transcribed by Starker, First Rhapsody by Béla Bartók and Sonata, Op. 108 by Johannes Brahms, transcribed by Hsiao-mei Sun.
