Sensitivity monitoring of Phakopsora pachyrhizi populations to triazoles in Brazil.

Asian soybean rust (ASR) reported in 2001 in South America spread to Brazilian producing areas and is considered one of the main diseases of the crop. Fungicides used for the control belong to QoI (strobilurins) and SBI (azole) compounds. A weaker efficacy of straight azole was observed at some regions in the end of the crop season 2006/2007. To determine whether the problem observed was due to the resistance, a sensitivity monitoring test was carried out in 2008/2009 to detect possible changes in the EC50 values of the fungus population. The test was done according to FRAC methodology. Leaves samples infected with Phakopsora pachyrhizi were sent from nine Brazilian states, in a total of 36 populations, and the spores collected were inoculated in detached leaves treated with fungicides. The triazoles tested were cyproconazole, metconazole, tebuconazole, and prothioconazole (0; 0.125; 0.25; 0.5; 1.0; 2.0; 4.0; 8.0; 16.0; 32.0 ppm). Disease severity was evaluated 15 days after inoculation. The EC50 values were estimated by Proc Probit, SAS®. Differences in EC50 values among the populations were statistically significant (P < 0.01). The EC50 for cyproconazole and metconazole ranged from 0.06 to 1.37 ppm and from 0.02 to 3.89 ppm, respectively. For tebuconazole, EC50 ranged from 0.02 to 1.28 ppm. For prothioconazole, there wasn’t a distribution of EC50 values because, with 0.25 ppm, the populations tested didn’t develop symptoms of ASR. The results showed an oscillation of EC50 values in the P. pachyrhizi population from different locations during the crop season

Inclusive Education and Cooperative Research in the ‘Adopting Sculptures’ Project

Esta experiencia parte de un modelo de educación artística inclusiva. De la propuesta destacamos el enfoque cooperativo e interdisciplinario y la reivindicación de las aportaciones instrumentales básicas de las competencias del ámbito artístico. El punto de partida es una iniciativa ya implantada en otros contextos, adaptado nuestro contexto educativo (universidad/escuela) a un proyecto ya existente llamado «Apadrinem escultures». La participación pluridisciplinar convirtió esta propuesta en un proyecto educativo y de investigación cooperativos entre estudiantes universitarios de final de grado, máster y doctorado, maestros en activo y alumnos de educación primaria. Asimismo se generaron propuestas para incidir en la formación permanente del profesorado, especialmente en el ámbito artístico.This experience was based on a model of inclusive arts education. From this model, one should stress the cooperative and interdisciplinary focus, as well as the contributions to the basic competences from the artistic field. Based on an initiative already implemented in other contexts, the project consisted of adapting it to local characteristics under the name ‘Let’s adopt a sculpture’. The pluridisciplinary dimension transformed this proposal into a cooperative educational research project among students from the last year of the degree, from the master’s degree or the Ph.D. studies, teachers and primary school students. From the project some new proposals to have an impact on permanent teacher training, especially in the artistic field, emerge

Effect of drying temperature on the nutritional quality of the pinhão (araucária angustifolia) flour.

At present, there is quite limited market for pinhão products due to their low level of industrialization. This study aimed to evaluate the drying process of pinhão at 40 oC, 50 oC and 60 °C for essential amino acids preservation in the final product. Effective diffusivity (Deff) was 15.6x10-10m2.s-1at 60 oC and the correspondent activation energy was 31.13 kJ. mol-1. Compared to raw pinhão, it was observed greater retention of the amino acid content for the pinhão flour obtained at 50 oC.Autoria: MATTOS, L. da S. de [i.e. NASCIMENTO, L. da S. de M.]
