Abstract: Described herein are various technologies pertaining to creating and modifying a computer-readable file for a patient in response to receiving data about the patient. The computer-readable file is modified by appending a child file record to the computer-readable file, identifying a parent file record for the child file record in the computer-readable file, and storing a pointer in the parent file record to the child file record. The child file record comprises the data about the patient, an initially empty pointer portion, and an attribute of a user that has permission to access the data about the patient. The pointer portion may be later modified to include pointers to subsequently added file records in the computer-readable file.

Abstract: A green ceramic core or other article at elevated temperature is placed between a complaint member and a relatively rigid setter while the green core or article cools to a lower temperature. The compliant member can comprise a fluid pressurized compliant bladder or a compliant, non-rigid setter or facing layer thereon for contacting a side of the green core or article.
