Experimental Use of Calcium Magnesium Acetate, Addendum, HR-253, 1984

The Iowa Department of Transportation Materials Laboratory personnel developed a process to produce a road deicer consisting of sand grains coated with calcium magnesium acetate (CMA). Research project HR-253 was established to explore commercial production of the CMA/sand deicer by an independent contractor. About 60 tons of the deicer was produced at a ready-mix concrete facility and evaluated in the field during the 1983-1984 winter season. The initial contracted production of CMA/sand deicer under research project HR-253 identified two major problems: (1) excessive unreacted lime in the final product, and (2) formation of spherical lumps within the product requiring subsequent size reduction. It was recommended in the HR-253 report that additional deicer be produced as a continuation of the project in order to address these problems and further develop the production process. A contract was negotiated with W. G. Block Co. to produce and deliver 50 tons of additional deicer. This addendum report covers this production effort including descriptions and results of all modifications of equipment and process procedures used.

Iowa Community Colleges Student Enrollment Report, December 2000

Fall enrollment grew 1.2 percent to a record high of 88,104 unduplicated students in fiscal year 2009 (Table 1). College enrollment has grown for 11 consecutive years since enrollment slipped in fiscal year 1997. In the 44‐year history of the modern community college system, enrollment has only fallen four times (Figure 1). Enrollment growth was slightly slower than prior years. In 2006, enrollment grew over three percent, while enrollment grew 2.5 percent last year. Nevertheless, enrollment growth is outpacing the projected nationwide growth in community colleges (Hussar and Bailey, 2008: Table 16). For the second consecutive year, part‐time enrollment exceeded full‐time enrollment. Slightly over half, 50.9 percent, of students are enrolled in less than 12 credit hours. Last year, part‐time enrollment exceeded full‐time enrollment for the first time. The shift represents growing enrollment by working students and joint enrollment— high school students who enroll in community colleges.. Nationally, part‐time enrollment at public two‐year colleges has exceeded full‐time enrollment for more than 15 years. In 2006, part‐time students exceeded full‐time students by 60 percent (Hussar and Bailey, 2008: Table 16). Iowa’s enrollment growth has traditionally been consistent. Enrollment decreased four times—1976, 1983, 1984, and 1997—during the entire 44‐year history. Fulltime enrollment decreased nine times over the same period while part time enrollment only fell twice. The remainder of this report will break down credit enrollment by credit hours, student demographics, the programs in which students are enrolled, how the programs break down demographically, and joint enrollment.

Iowa "50 States Project": A Review of the 1983 Code for Sexuality Discrimination, February 1984

The "50 States Project" is the name given to President Ronald D. Reagan;s 1981 pledge to encourage the fifty governors to initiate individual state projects to review their state Codes for unequal treatment of persons based upon sex. We believe that Iowa is the first state to complete this project. Project efforts in Iowa began in June of 1981, when the Governor Robert D. ray appointed Dr. Patricia L. Geadelmann, Chairperson on the Iowa commission on the Status of Women, as Iowa's 50 State Project representative. A 50 States planning committee was formed consisting of members from the Governor Ray's staff, the Iowa Commission on the Status of Women, and the Iowa Legislature. Various alternatives for reviewing the Iowa code and the Iowa Administrative Rules were studied and recommendations of the group were reported to Governor Terry E. Branstad prior to his inauguration.
