the quality evaluation of agricultural products is one of the key factors in promoting their quality. in this study, a method based on combined image processing technique and artificial neural network was presented. separation of touching almonds under different positions is a very important step in design of grading devices. in this study, an image processing algorithm based on extracting crit...

Simultaneous coinfection of Spodoptera frugiperda cells with baculovirus recombinants containing the genes for VP6 and VP7 of bovine rotavirus strain C486 resulted in the production of spherical particles resembling smooth, double-shelled rotavirus. These particles were predominantly located in the cell culture supernatant instead of being cell associated. Pretreatment of infected-cell culture ...

Unlike the multiple-shelled organization of other Reoviridae members, cytoplasmic polyhedrosis virus (CPV) has a single-shelled capsid. The three-dimensional structures of full and empty CPV by electron cryomicroscopy show identical outer shells but differ inside. The outer surface reveals a T=1 icosahedral shell decorated with spikes at its icosahedral vertices. The internal space of the empty...
