in this study, the vibration of cracked plates is investigated using the differential quadrature method and experimental modal analysis. the crack, which is assumed to be open, is modeled by the extended rotational spring. with its finite length, the crack divides the plate into six segments. then, the differential quadrature is applied to the governing differential equations of motion and the ...

Two tremorgenic mycotoxins were isolated from Aspergillus caespitosus, and identified as verruculogen and fumitremorgin B. They were produced at the rate of 172 and 325 mg per kg, respectively, on autoclaved cracked field corn.
