Predictive plots for conical pick performance using mechanical and elastoplastic properties of rocks

Journal of Rock Mechanics and Geotechnical Engineering, 2020
Conical picks are by far the most widely used drag type cutting tools employed on partial face rock excavation machines. The cutting force and specific energy are two important design parameters for the conical pick performance, and the rock cutting ...

The mode of inheritance in tetraploid cut roses [PDF]

Theoretical and Applied Genetics, 2012
Tetraploid hybrid tea roses (Rosa hybrida) represent most of the commercial cultivars of cut roses and form the basis for breeding programmes. Due to intensive interspecific hybridizations, modern cut roses are complex tetraploids for which the mode of inheritance is not exactly known.
