Revista Brasileira de Engenharia Agrícola e Ambiental, 2003 O Brasil é o maior produtor mundial de cana-de-açúcar. A mecanização da colheita tornou-se uma necessidade dos tempos modernos, mas perdas de 10 a 15% são freqüentes quando a cana é colhida crua. A deflexão e o corte de base são responsáveis por danos na

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1
Cytoskeleton, EarlyView.ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Study on the effect of bionic flap based on owl wing contour on aerodynamic noise of airfoil
International Journal of Renewable Energy DevelopmentModifying flap geometry to reduce trailing-edge turbulence is an effective approach to lower wind-turbine blade aerodynamic noise. Based on the NACA0018 airfoil, a new bionic serrated flap was designed by mimicking the owl wing structure.

Developmental Dynamics, EarlyView.Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Equine Veterinary Journal, EarlyView.Abstract Background Ossifying fibromas are uncommon in horses and complete surgical excision with premaxillectomy, maxillectomy or mandibulectomy is recommended. Piezosurgery has been previously used in equines only in one study. Objective To report a case of ossifying fibroma treated with piezosurgery and to describe its follow‐up.
