Das raízes

O objetivo deste projeto artístico foi desenvolver um conhecimento mais aprofundado relacionado com a execução e interpretação de técnicas de percussão tradicionais aliadas a técnicas contemporâneas. De entre as várias técnicas tradicionais de percussão optei por desenvolver as da percussão Africana (Guiné e Burkina Faso, e mais tarde Nigéria) e as da percussão Cubana. Criei assim um projeto artístico de fusão intitulado Das Raízes, no qual ao longo dos dois anos do curso de mestrado estive em contacto com a música Africana e Cubana aliada a técnicas contemporâneas e composições originais (minhas e de outros compositores). Para cada obra explorei primeiro as técnicas tradicionais e em seguida adaptei-as à percussão contemporânea, num processo onde as suas raízes africanas, cubanas ou até afro- cubanas são evidentes. Neste projeto salienta-se o papel preponderante das mãos. No século XXI o uso da baqueta predomina como a técnica mais forte para dominar os instrumentos nos conservatórios e nas escolas superiores de música. Após ter adquirido esta técnica resolvi aprofundar as técnicas tradicionais onde predominam o uso não só da baqueta mas também da mão, um mundo antigo na sua existência, mas novo para mim. Espero poder transportar o ouvinte para um mundo em que cor, movimento e som, antiguidade e contemporaneidade estão em constante vibração.

Efeito da associação de sabor e música sobre o estado de ânimo de crianças

Este estudo teve como objetivo avaliar como sabor e música exercem efeito sobre o estado de ânimo de crianças. Participaram 83 crianças de 5 a 10 anos de idade e de ambos os sexos. A tarefa dos participantes consistiu em experimentar o sabor de soluções doce e amarga na ausência de música e na presença de músicas pré-qualificadas como alegres e tristes, e depois, julgar o estado de ânimo decorrente da experimentação. O julgamento do estado de ânimo das crianças se modificou quando o sabor era amargo e as músicas eram alegres, caso em que o estado de ânimo se alterou de triste para alegre; quando o sabor era doce e as músicas tristes, o estado de ânimo passou de alegre para triste. Futuros trabalhos podem observar crianças realizando tarefas que apresentem contextos de alimentos reais associados à estimulação musical.

Survival of conidia of sorghum ergot (caused by Claviceps africana) on panicles, seed and soil in Australia

Macroconidia of the sorghum ergot pathogen, Claviceps africana Frederickson, Mantle & de Milliano, survived in dried honeydew on soil for 13-14 weeks in a glasshouse at ambient temperatures, but for less than half that time on seed stored in a shadehouse over summer. Those on seeds stored at 4degreesC, however, survived for over a year (58-62 weeks). During summer, conidia on ergot-infected panicles buried in soil, or on the soil surface, survived for 7.5-12 weeks, whereas over winter the survival times were 4 weeks and 19-27 weeks, respectively. Macroconidia on infected panicles held above the soil surface survived for >38 weeks (8 calendar months) over winter, suggesting that they may play a role in the perennation of C. africana in Australia.

Factors influencing the germination of macroconidia and secondary conidia of Claviceps africana

The influences of temperature, time, and moisture on the germination of macroconidia and secondary conidia of Australian isolates of Claviceps africana were studied in vitro. The optimum temperature for germination of both macroconidia and secondary conidia of C. africana was 20degreesC. Although germination of macroconidia ceased near 31degreesC, approximately 30% of secondary conidia germinated at 37degreesC after 48 and 72 h of incubation. Sorghum flower extract agar stimulated macroconidium and secondary conidium germination, irrespective of temperature. Germination of macroconidia and secondary conidia on water agar started after 4 h of incubation at 20degreesC, reaching a maximum after 16-24 h and 14 h, respectively. Maximum germination of both macroconidia and secondary conidia was at greater than or equal to-5 bars at 20degreesC. Germination of secondary conidia ceased at -35 bars, whereas macroconidia germinated at water potentials as low as -55 bars at 20degreesC.

Evaluation of potential biocontrol agents against Claviceps africana in vitro and in vivo

Undiluted culture filtrates of two commercial products of Trichoderma spp., Trichopel and Trichoflow, and two isolates of Penicillium citrinum completely inhibited the conidial germination of macroconidia of Claviceps africana , the cause of ergot or sugary disease of sorghum (Sorghum bicolor) in vitro . Similarly, Pseudomonas aeruginosa and Burkholderia cepacia completely inhibited macroconidial germination, with the former being more effective at high dilutions. In contrast, these bacterial isolates failed to inhibit infection in vivo in glasshouse tests with ergot-inoculated sorghum, but all fungal biocontrol agents (including an isolate of Epicoccum nigrum) reduced the severity of disease (percentage of infected spikelets per panicle), in some cases completely inhibiting the development of ergot. In a second glasshouse trial, optimum control was achieved when the biocontrol agents were applied 3-7 days before inoculation with conidia of C. africana .

Efficacy, timing and method of application of fungicides for management of sorghum ergot caused by Claviceps africana

Trials conducted in Queensland, Australia between 1997 and 2002 demonstrated that fungicides belonging to the triazole group were the most effective in minimising the severity of infection of sorghum by Claviceps africana, the causal agent of sorghum ergot. Triadimenol ( as Bayfidan 250EC) at 0.125 kg a. i./ha was the most effective fungicide. A combination of the systemic activated resistance compound acibenzolar-S-methyl ( as Bion 50WG) at 0.05 kg a. i./ha and mancozeb ( as Penncozeb 750DF) at 1.5 kg a. i./ha has the potential to provide protection against the pathogen, should triazole-resistant isolates be detected. Timing and method of fungicide application are important. Our results suggest that the triazole fungicides have no systemic activity in sorghum panicles, necessitating the need for multiple applications from first anthesis to the end of flowering, whereas acibenzolar-S-methyl is most effective when applied 4 days before flowering. The flat fan nozzles tested in the trials provided higher levels of protection against C. africana and greater droplet deposition on panicles than the tested hollow cone nozzles. Application of triadimenol by a fixed wing aircraft was as efficacious as application through a tractor-mounted boom spray.

Ovary colonization by Claviceps africana is related to ergot resistance in male-sterile sorghum lines

Ergot, caused by Claviceps africana, has emerged as a serious threat to sorghum hybrid seed production worldwide. In the absence of gene-for-gene-based qualitative resistance in commercial cultivars, varieties with high pollen production that can escape ergot infection are preferred. Recent demonstration of differences in ergot susceptibility among male-sterile lines has indicated the presence of partial resistance. Using chitin-specific fluorescin-isothiocyanate-conjugated wheat germ agglutin and callose-specific aniline blue, this study investigated the process of sorghum ovary colonization by C. africana. Conidia germinated within 24 h after inoculation (a.i.); the pathogen was established in the ovary by 79 h a.i., and at least half of the ovary was converted into sphacelial tissue by 120 h a.i. Changes in fungal cell wall chitin content and strategic callose deposition in the host tissue were associated with penetration and invasion of the ovary. The rate of ovary colonization differed in three male-sterile lines that also differed in ergot susceptibility. This work demonstrates a possible histological basis for partial resistance in male-sterile sorghum lines that could lay the foundation for variety improvement through further breeding and selection.
