Iowa Immunization Program Annual Report 2013, April 30, 2014

The Bureau of Immunization is part of the Division of Acute Disease Prevention and Emergency Response (ADPER) at the Iowa Department of Public Health (IDPH). The ADPER division provides support, technical assistance and consultation to local hospitals, public health agencies, community health centers, emergency medical service programs and local health care providers regarding infectious diseases, disease prevention and control, injury prevention and public health and health care emergency preparedness and response. The division encompasses the Center for Acute Disease Epidemiology (CADE), the Bureau of Immunization and Tuberculosis (ITB), the Bureau of Emergency Medical Services (EMS), the Bureau of Communication and Planning (CAP), the Office of Health Information Technology (HIT), and the Center for Disaster Operations and Response (CDOR). The Bureau of Immunization and Tuberculosis includes the Immunization Program, the Tuberculosis Control Program, and the Refugee Health Program. The mission of the Immunization Program is to decrease vaccine‐preventable diseases through education, advocacy and partnership. While there has been major advancement in expanding immunizations to many parts of Iowa’s population, work must continue with public and private health care providers to promote the program’s vision of healthy Iowans living in communities free of vaccine‐preventable diseases. Accomplishing this goal will require achieving and maintaining high vaccination coverage levels, improving vaccination strategies among under‐vaccinated populations, prompt reporting and thorough investigation of suspected disease cases, and rapid institution of control measures. The Immunization Program is comprised of multiple programs that provide immunization services throughout the state: Adolescent Immunization Program, Adult Immunization Program, Immunization Registry Information System (IRIS), Vaccines for Children Program (VFC), Perinatal Hepatitis B Program, and Immunization Assessment Program.

A Sufficiency Rating System for Secondary Roads in Iowa, HR-264, 1985

County engineers in Iowa face the dual problems of rapidly escalating costs and a decreasing rate of growth of revenues. Various priority systems are in use, ranking projects for inclusion in road improvement programs, but they generally have weaknesses when used to compare one project with another in a different location. The sufficiency rating system has proven to be a useful tool in developing a priority list of projects for primary road systems, but there are none currently in use for secondary road systems. Some elements of an existing system used for primary roads could be modified for use with secondary roads, but would require extensive changes. The research reported here, sponsored by the Iowa Department of Transportation, was undertaken to develop a sufficiency rating system which could be used for secondary roads in Iowa and to produce the necessary forms and instructions to aid county engineering personnel in their efforts to complete the ratings for roads within their county. If a usable system were available that would yield reasonable results, county engineers would have an additional tool available to assist them in arriving at a defensible road improvement program.

Evaluation of the Chemical Durability of Iowa Fly Ash Concretes, HR-327, Phase II Progress Report, 1992

The major objective of this research project is to investigate how fly ash influences the chemical durability of portland cement based materials. The testing program is evaluating how Iowa fly ashes influence the sulfate durability of portland cement-fly ash pastes, mortars, and concretes. Also, alkali-reactivity studies are being conducted on mortar bar specimens prepared in accordance with ASTM C 311. Prelimary sulfate test results, based only on mortar bar studies, indicate that only the very high-calcium fly ash (29 percent CaO, by weight) consistently reduced the durability of test specimens exposed to a solution containing 5 percent sodium sulfate. The remaining four fly ashes that were used in the study showed negligible to dramatic increases in sulfate resistance. Concrete specimens were only beginning to respond to the sulfate solutions after about one year of exposure; and hence, considerably more time will be needed to assess their performance. Preliminary results from the alkali-reactivity tests have indicated that the Oreopolis aggregate is not sensitive to alkali attack. However, some of the test results have indicated that the testing procedure may be prone to delayed expansion due to the presence of periclase (MgO) in the Class C fly ashes. Research is being planned to: (1) verify if the periclase is influencing test results; and (2) estimating the magnitude of the potential error.

Comparison Between Leaded and Nonleaded Gasoline as Used in Iowa State Highway Commission Vehicles, HR-1002, 1972

The overall objective of this experimental program was to obtain quantitative comparisons between leaded and nonleaded gasolines as used in a variety of Iowa State Highway Connnission vehicles. These quantitative comparisons were to be made in terms of exhaust emissions, maintenance costs and fuel economy.

Soil Stabilization with Lime, Iowa Highway Research Board Bulletin No. 25, 1961

This is the fifth publication in a series of compilations of the reports on research completed for the Iowa State Highway Commission. This research was done for the Iowa State Highway Research Board Project HR-1, "The Loess and Glacial Till Materials of Iowa; an Investigation of Their Physical and Chemical Properties and Techniques for Processing Them to Increase Their All-Weather Stability for Road Construction." The research, started in 1950, was done by the Iowa Engineering Experiment Station under its project 283-S. The project was supported by funds from the Iowa State Highway Commission. The principal objectives of the project may be summed up as follows: 1. To determine by means of both field and laboratory studies the areal and stratigraphic variation in the physical and chemical properties of the loess and glacial till materials of Iowa. 2. To develop new equipment and methods for evaluating physical and chemical properties of soil where needed. 3. To correlate fundamental soil properties with the performance of soils in the highway structure. 4. To develop a scientific approach to the problem of soil stabilization based on the relationships between the properties of the soils and those of the admixtures. 5. To determine the manner in which the loess and glacial till materials of Iowa can be processed for optimum performance as highway embankments, sub-grades, base courses, and surface courses.

Iowa Highway Research Report No. 2, 1950-1951

During the fiscal year, July 1, 1950 to June 30, 1951, the Iowa State Highway Commission expanded its research program by adding to the work under way during the previous fiscal year, fifteen substantial projects recommended to the Commission by the Iowa Highway Research Board. The major portion of the projects under way in the previous fiscal year have been active in this fiscal year. All of the additional projects have gotten under way during this fiscal year. This year, as in the past, the work has been performed partly by Commission forces and partly by outside agencies such as the Institute of Hydraulic Research at Iowa City, the State University of Iowa, Iowa State College, the Iowa Geological Survey and the United States Geological Survey. The major portion of the fifteen new projects has been assigned to these outside agencies.
