Phil Armitage. Colorado. Processes in Protoplanetary Disks. Disk structure. Disk evolution. Turbulence. Episodic accretion. Single particle evolution. Ice lines and persistent radial structure. Transient structures in disks. Packaging samples for irradiation. Overview. Care must be taken while packaging groundmass and mineral separates to prevent loss of sample and cross-contamination of adjacent samples.. Because the geometric position of samples and standards is critical, labelling throughout the process is important.. Lecturer: . Ofer. Rothschild. 1. Problem with the borders. 2.
