Double cantilever beam (DCB) tests are common experiments in the field of adhesive fracture mechanics. During such an experiment, both the load and the crack length have to be monitored. Digital image processing techniques offer interesting possibilities in various fields of science. Automated analyses may significantly reduce the necessary manpower for certain cumbersome tasks. The analysis of large series of ...

Oliveira,M.C.; Rodrigues,E.A.; Marques,R.H.; Gravena,R.A.; Guandolini,G.C.; Moraes,V.M.B.

The performance and the morphology of intestinal mucosa of broilers fed mannan-oligosaccharides (MOS) and enzymes (E) from one to 21-day-old were evaluated using 750 one-day-old chicks, assigned to a 2 x 2 + 1 factorial design - two levels of MOS (0 and 0.1%), two levels of E (0 and 0.05%) plus an antibiotic positive control diet - performing five treatments of five replications each one. MOS x E interaction wa...
