DYNAMIC MODELLING OF VIBRATIONS ASSISTED DRILLING

DYNAMIC MODELLING OF VIBRATIONS ASSISTED DRILLING

The number of multi-materials staking configurations for aeronautical structures is increasing, with the evolution of composite and metallic materials.For drilling the fastening holes, the processes of Vibration Assisted Drilling (VAD) expand rapidly, as it permits to improve reliability of drilling operations on multilayer structures.Among these S

An in vitro-identified high-affinity nucleosome-positioning signal is capable of transiently positioning a nucleosome in vivo

Abstract Background The physiological function of eukaryotic DNA occurs in the context of nucleosomal arrays that can expose or obscure defined segments of the genome.Certain DNA sequences are capable of strongly positioning a nucleosome in vitro, suggesting the possibility that favorable intrinsic signals might reproducibly structure chromatin seg

Assessing Legacy Effects of Wildfires on the Crown Structure of Fire-Tolerant Eucalypt Trees Using Airborne LiDAR Data

The fire-tolerant eucalypt forests of south eastern Australia are assumed to fully recover from even the most intense fires; however, surprisingly, very few studies have quantitatively assessed that recovery.The accurate assessment of horizontal and vertical attributes of tree crowns after fire is essential to understand the fire’s legacy eff
