Nuclear Waste Into Glass: Viscosities Of Molten Analogs Of Radioactive Waste Disposal Media, Betty Pang, Kenneth E. Windom

Journal of the Iowa Academy of Science: JIAS

Disposal of high-level radioactive wastes involves vitrification of a mixture of waste products and borosilicate glass frit. Monitoring the composition of the mixture is critical to the control of the vitrification process, bur is difficult because of the high levels or radioactive components in the mixture. Synthetic non-radioactive analogs of the products from nuclear reprocessing have been prepared and their viscosities measured over a wide range of temperature appropriate to those of the vitrification process. Preliminary results indicate that viscosity is a linear function of composition, under isothermal conditions, for a limited compositional range that encompasses the proportions of waste …

Water Quality Monitoring (1988 To 1991) At The Iowa Academy Of Science's Parish Farm, Grundy County, Iowa, Brenda K. Nations, George R. Hallberg

Journal of the Iowa Academy of Science: JIAS

In May 1988 sampling was initiated to evaluate water quality in relation to management practices at Parish Farm, which is owned by Iowa Academy of Science. Initial results showed tile-line effluent to have high concentrations of nitrate-nitrogen (N0₃-N). Twelve monitoring wells were installed over a one year period to analyze shallow groundwater at the farm. The wells, tile lines, and surface water were sampled monthly, through October, 1991, and the water analyzed for N0₃-N and some pesticides. N0₃-N concentrations varied, related to landuse and management of adjacent areas. Greater N0₃-N concentrations were …

The Effectiveness Of Discis Books When Used To Improve Reading Scores Of Kinesthetic, Below Grade-Level Learners, Michelle Bentler

Graduate Research Papers

A reading comprehension study using Discis Books and below grade level sixth grade readers at Harmony Middle School, Farmington, Iowa, testing positive as kinesthetic learners, was carried out in a nine week time period. The study's participants completed a learning styles inventory and a comprehension reading inventory. Students were then randomly divided into experimental and control groups. The control group participated in classroom instruction and independent silent reading. The experimental group participated in classroom instruction and computer­ assisted instruction. A post comprehension inventory was administered.

Data were collected to determine if kinesthetic learners improved reading comprehension through the use of …
