Measurement of coherent π+π^{+} production in low energy neutrino-Carbon scattering

We report the first measurement of the flux-averaged cross section for charged current coherent $\pi^{+}$ production on carbon for neutrino energies less than 1.5 GeV to a restricted final state phase space region in the T2K near detector, ND280. Comparisons are made with predictions from the Rein-Sehgal coherent production model and the model by Alvarez-Ruso {\it et al.}, the latter representing the first implementation of an instance of the new class of microscopic coherent models in a neutrino interaction Monte Carlo event generator. This results contradicts the null results reported by K2K and SciBooNE in a similar neutrino energy region

Comparative study of adenoviruses with monoclonal antibodies Estudo comparativo de diferentes tipos de adenovirus através de anticorpos monoclonais

The obtainment of monoclonal antibodies for adenovirus species 4(Ad4) is described.The specificities of selected monoclonal antibodies were determined by means of viral neutralization test in cell culture, immunofluorescence and Enzyme-Linked Immunosorbent Assay (ELISA), in the presence of the following species of human adenovirus: 1, 2, 5 (subgenus C), 4 (subgenus E), 7 and 16 (subgenus B) and 9 (subgenus D). Two monoclonal antibodies species specific to adenovirus 4 (1CIII and 3DIII) and one monoclonal antibody that cross reacted with adenovirus species 4 and 7 (2HIII) were obtained.<br>O estudo relata a obtenção de anticorpos monoclonais para o adenovirus tipo (espécie) 4. A especificidade dos anticorpos monoclonais, selecionados nesse experimento, foi determinada testando-os frente às diferentes espécies de adenovírus: 1, 2, 5 (subgênero C), 4 (subgênero E), 7 e 16 (subgênero B) e 9 (subgênero D), pelas técnicas de neutralização em cultura de células, imunofluorescência e ensaio imunoenzimático (ELISA). Os resultados demonstram a obtenção de anticorpos monoclonais que reagiram de maneira específica para o adenovírus 4 (1CIII e 3DIII) e anticorpo monoclonal apresentando reação cruzada com as espécies de adenovírus 4 e 7 (2HIII)
