Field Data Acquisition Technologies for Iowa Transportation Agencies, HR-366 August 1994

This report describes the results of the research project investigating the use of advanced field data acquisition technologies for lowa transponation agencies. The objectives of the research project were to (1) research and evaluate current data acquisition technologies for field data collection, manipulation, and reporting; (2) identify the current field data collection approach and the interest level in applying current technologies within Iowa transportation agencies; and (3) summarize findings, prioritize technology needs, and provide recommendations regarding suitable applications for future development. A steering committee consisting oretate, city, and county transportation officials provided guidance during this project. Technologies considered in this study included (1) data storage (bar coding, radio frequency identification, touch buttons, magnetic stripes, and video logging); (2) data recognition (voice recognition and optical character recognition); (3) field referencing systems (global positioning systems [GPS] and geographic information systems [GIs]); (4) data transmission (radio frequency data communications and electronic data interchange); and (5) portable computers (pen-based computers). The literature review revealed that many of these technologies could have useful applications in the transponation industry. A survey was developed to explain current data collection methods and identify the interest in using advanced field data collection technologies. Surveys were sent out to county and city engineers and state representatives responsible for certain programs (e.g., maintenance management and construction management). Results showed that almost all field data are collected using manual approaches and are hand-carried to the office where they are either entered into a computer or manually stored. A lack of standardization was apparent for the type of software applications used by each agency--even the types of forms used to manually collect data differed by agency. Furthermore, interest in using advanced field data collection technologies depended upon the technology, program (e.g.. pavement or sign management), and agency type (e.g., state, city, or county). The state and larger cities and counties seemed to be interested in using several of the technologies, whereas smaller agencies appeared to have very little interest in using advanced techniques to capture data. A more thorough analysis of the survey results is provided in the report. Recommendations are made to enhance the use of advanced field data acquisition technologies in Iowa transportation agencies: (1) Appoint a statewide task group to coordinate the effort to automate field data collection and reporting within the Iowa transportation agencies. Subgroups representing the cities, counties, and state should be formed with oversight provided by the statewide task group. (2) Educate employees so that they become familiar with the various field data acquisition technologies.

An Architectural and Historical Survey of Public Libraries in Iowa 1870-1940, 1980

The public library movement f the early twentieth century was a national phenomenon, in which Iowa, along with its neighboring states, played a prominent role. In 1900, the Iowa Library Commission noted 48 free public libraries in the state. Today there are approximately 500, in towns ranging in size from Beaman, with a population of 222, the Des Moines, the state capitol. Iowans took enthusiastic advantage of Andre Carnegie's library philanthropy. In 1919, the Carnegie Corporation stopped funding libraries, 101 building has been erected in Iowa with Carnegie funds. Iowa place fourth among the states in terms of the number of communities obtaining Carnegie buildings, fifth in dollar appropriation per one hundred population and eighth in the total amount of money given by Carnegie to a state. These figures provide some measure by which interest in popular education among Iowans of the period can be judged. Today these early libraries, often the most distinctive public libraries in small or medium-sized towns, are physical foci in the townscapes of their communities and centers for a variety of educational and social activities. This survey was initiated by the Division of Historic Preservation in 1977. It grew out of the need to provide a framework within which libraries could be evaluated for National Register action. Several libraries (Des Moines, Grinnell, Eagle Grove, Carroll) has been recent candidates for the Register. There was every indication that enthusiasm for old library buildings was increasing and that more nominations could be expected in the future. The attrition rate among early library buildings was (and is) growing. Most libraries were built on limited budgets (Carnegie did not squander his money) and, despite the fact that future expansion was usually a conscious consideration in their design, they are rapidly becoming obsolete, due to expanding collections and changing styles of librarianship. If the protection of the threatened with demolition or alteration, action needed to be taken.

Freeze-Thaw Durability of Concretes with and without Class C Fly Ash, MLR-94-9 Phase I, 1997

The freeze-thaw resistance of concretes was studied. Nine concrete mixes, made with five cements and cement-Class C fly ash combinations, were exposed to freeze-thaw cycling following 110 to 222 days of moist curing. Prior to the freeze-thaw cycling, the specimens were examined by a low-vacuum scanning electron microscope (SEM) for their microstructure. The influence of a wet/dry treatment was also studied. Infilling of ettringite in entrained air voids was observed in the concretes tested. The extent of the infilling depends on the period of moist curing as well as the wet/dry treatment. The concretes with 15% Class C fly ash replacement show more infilling in their air voids. It was found that the influence of the infilling on the freeze-thaw durability relates to the air spacing factor. The greater the spacing factor, the more expansion under the freeze-thaw cycling. The infilling seems to decrease effective air content and to increase effective spacing factor. The infilling also implies that the filled air voids are water-accessible. These might lead to concrete more vulnerable to the freeze-thaw attack. By combining the above results with field observations, one may conclude that the freeze-thaw damage is a factor related to premature deterioration of portland cement concrete pavements in Iowa.

2009 Calendar Year Annual Report of the Watershed Improvement Review Board

The Board, codified in Chapter 466A, is an independent, self-governing body directed to award grants for water quality improvement and flood prevention in the state. The Board is authorized to request applications from soil and water conservation districts, local watershed improvement committees, public water supply utilities, counties, county conservation boards and cities and award grants to these entities. These grants are issued from the Watershed Improvement Fund. Annual appropriations of $5 million plus interest earned on the Watershed Improvement Fund allowed the Board to issue two Request For Applications in 2009. On February 27, the Board awarded grants to seven applicants for a total of $2,366,861. On September 21, the Board awarded grants to thirteen applicants for a total of $5,120,832. In addition to providing environmental benefits, these implementation projects stimulate economic recovery and create jobs through the purchasing oflocal goods and services.
