Artificial Teeth For Permanent Implantation, Theresa Janikowski, Thomas D. Mcgee
Proceedings of the Iowa Academy of Science
Artificial teeth with a low solubility and with properties similar to natural teeth were produced for implantation tests. The teeth were made from MgAl2O4 spinel and Ca3(PO4)2 Whitlockite to achieve low solubility and non-toxic reaction products. The method of manufacture is described.

The Multistructured Course - A Preliminary Analysis, Paul A. Meglitsch
Proceedings of the Iowa Academy of Science
An experimental program in which students may enroll in courses for varying amounts of credit, and select course objectives that are in line with their educational goals is described. A preliminary analysis of the results indicates that students tend strongly to approve of the goals of the experiment, have performed well, and, on the whole, react positively to the educational conditions involved. Early evaluation appears to show that some of the techniques commonly used for introductory courses are applicable, and others not very applicable, to education in courses involving upper division and graduate students.
