Alternative Flexible Overlays, HR-229, 1988

The objective of this project was to determine if any of several cutback and emulsified asphalt plant mixed and road mixed overlays had the ability to resist thermal cracking at low temperatures without inducing shoving and/or ruttinq at high temperatures. A 2.6 mile section of Osceola County road A-34 and a 7.0 mile section of A-46 were divided into 14 test sections of various lengths. After six years, results show an MC-3000 asphalt cutback cold mix can reduce the amount of reflective cracking when compared to an AC-5 hot mix. This can be done without inducing high temperature related problems. Cold road mixing can be effective in reducing cracking on low volume roads. However, more experience is required if the full benefits of road mixing are to be realized.

Burden of Diabetes in Iowa 1991-2009, Final Report, May 2010

The Iowa Diabetes Prevention and Control Program provides educational opportunities for health care providers via the Iowa Communications Network interactive fiber optic system. The program also certifies diabetes outpatient education programs in Iowa based on minimum criteria for quality programs. In Iowa during the past 20 years, the prevalence rate of diagnosed diabetes increased dramatically among adults: Between 1991 and 2009 the crude diabetes prevalence rate rose by 84%, from 3.8% to 7.0%. Between these years, the age���adjusted adult diagnosed diabetes prevalence rate increased by 64%, rising from 3.7% to 6.4%. During the 18 years 1991���93 through 2006���08, the number of Iowa adults with diagnosed diabetes more than doubled, increasing from 78,000 to 162,000. While the Iowa Behavioral Risk Factor Surveillance System (BRFSS), upon which the numbers cited above are based, provides reliable state���level self���reported data on adults with diagnosed diabetes, it is unable to provide estimates of undiagnosed diabetes. National estimates put the prevalence of undiagnosed adult diabetes at about 5%, raising the estimated adult diabetes prevalence rate in Iowa to 12% (280,000 adults) (Cowie,2009). Another 5% of all Iowa adults are estimated to have diagnosed pre���diabetes, while 25% of all Iowa adults, based on national estimates from the 2005���06 National Health and Nutrition and Examination Survey (NHANES), likely have undiagnosed pre���diabetes.
