Coming into Focus A Needs Assessment and State Plan for Iowans with Brain Injury, November 1998

Coming Into Focus presents a needs assessment related to Iowans with brain injury, and a state action plan to improve Iowa’s ability to meet those needs. Support for this project came from a grant from the Office of Maternal and Child Health to the Iowa Department of Public Health, Iowa’s lead agency for brain injury. The report is a description of the needs of people with brain injuries in Iowa, the status of services to meet those needs and a plan for improving Iowa’s system of supports. Brain injury can result from a skull fracture or penetration of the brain, a disease process such as tumor or infection, or a closed head injury, such as shaken baby syndrome. Traumatic brain injury is a leading cause of death and disability in children and young adults (Fick, 1997). In the United States there are as many as 2 million brain injuries per year, with 300,000 severe enough to require hospitalization. Some 50,000 lives are lost every year to TBI. Eighty to 90 thousand people have moderate to acute brain injuries that result in disabling conditions which can last a lifetime. These conditions can include physical impairments, memory defects, limited concentration, communication deficits, emotional problems and deficits in social abilities. In addition to the personal pain and challenges to survivors and their families, the financial cost of brain injuries is enormous. With traumatic brain injuries, it is estimated that in 1995 Iowa hospitals charged some $38 million for acute care for injured persons. National estimates offer a lifetime cost of $4 million for one person with brain injury (Schootman and Harlan, 1997). With this estimate, new injuries in 1995 could eventually cost over $7 billion dollars. Dramatic improvements in medicine, and the development of emergency response systems, means that more people sustaining brain injuries are being saved. How can we insure that supports are available to this emerging population? We have called the report Coming into Focus, because, despite the prevalence and the personal and financial costs to society, brain injury is poorly understood. The Iowa Department of Public Health, the Iowa Advisory Council on Head Injuries State Plan Task Force, the Brain Injury Association of Iowa and the Iowa University Affiliated Program have worked together to begin answering this question. A great deal of good information already existed. This project brought this information together, gathered new information where it was needed, and carried out a process for identifying what needs to be done in Iowa, and what the priorities will be.

Western Iowa Missouri River Flooding -- Geo-Infrastructure Damage Assessment, Repair and Mitigation Strategies, TR-638, 2013

The 2011 Missouri River flooding caused significant damage to many geo-infrastructure systems including levees, bridge abutments/foundations, paved and unpaved roadways, culverts, and embankment slopes in western Iowa. The flooding resulted in closures of several interchanges along Interstate 29 and of more than 100 miles of secondary roads in western Iowa, causing severe inconvenience to residents and losses to local businesses. The main goals of this research project were to assist county and city engineers by deploying and using advanced technologies to rapidly assess the damage to geo-infrastructure and develop effective repair and mitigation strategies and solutions for use during future flood events in Iowa. The research team visited selected sites in western Iowa to conduct field reconnaissance, in situ testing on bridge abutment backfills that were affected by floods, flooded and non-flooded secondary roadways, and culverts. In situ testing was conducted shortly after the flood waters receded, and several months after flooding to evaluate recovery and performance. Tests included falling weight deflectometer, dynamic cone penetrometer, three-dimensional (3D) laser scanning, ground penetrating radar, and hand auger soil sampling. Field results indicated significant differences in roadway support characteristics between flooded and non-flooded areas. Support characteristics in some flooded areas recovered over time, while others did not. Voids were detected in culvert and bridge abutment backfill materials shortly after flooding and several months after flooding. A catalog of field assessment techniques and 20 potential repair/mitigation solutions are provided in this report. A flow chart relating the damages observed, assessment techniques, and potential repair/mitigation solutions is provided. These options are discussed for paved/unpaved roads, culverts, and bridge abutments, and are applicable for both primary and secondary roadways.

Assessment of Nondestructive Testing Technologies for Quality Control/Quality Assurance of Asphalt Mixtures, TR-653, 2015

Asphalt pavements suffer various failures due to insufficient quality within their design lives. The American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide (MEPDG) has been proposed to improve pavement quality through quantitative performance prediction. Evaluation of the actual performance (quality) of pavements requires in situ nondestructive testing (NDT) techniques that can accurately measure the most critical, objective, and sensitive properties of pavement systems. The purpose of this study is to assess existing as well as promising new NDT technologies for quality control/quality assurance (QC/QA) of asphalt mixtures. Specifically, this study examined field measurements of density via the PaveTracker electromagnetic gage, shear-wave velocity via surface-wave testing methods, and dynamic stiffness via the Humboldt GeoGauge for five representative paving projects covering a range of mixes and traffic loads. The in situ tests were compared against laboratory measurements of core density and dynamic modulus. The in situ PaveTracker density had a low correlation with laboratory density and was not sensitive to variations in temperature or asphalt mix type. The in situ shear-wave velocity measured by surface-wave methods was most sensitive to variations in temperature and asphalt mix type. The in situ density and in situ shear-wave velocity were combined to calculate an in situ dynamic modulus, which is a performance-based quality measurement. The in situ GeoGauge stiffness measured on hot asphalt mixtures several hours after paving had a high correlation with the in situ dynamic modulus and the laboratory density, whereas the stiffness measurement of asphalt mixtures cooled with dry ice or at ambient temperature one or more days after paving had a very low correlation with the other measurements. To transform the in situ moduli from surface-wave testing into quantitative quality measurements, a QC/QA procedure was developed to first correct the in situ moduli measured at different field temperatures to the moduli at a common reference temperature based on master curves from laboratory dynamic modulus tests. The corrected in situ moduli can then be compared against the design moduli for an assessment of the actual pavement performance. A preliminary study of microelectromechanical systems- (MEMS)-based sensors for QC/QA and health monitoring of asphalt pavements was also performed.

Iowa Fen Rapid Assessment Method for Wetlands v. 1 Quantitative Rating, 2016

Rapid assessment methods are valuable tools for collecting information about the quality and status of natural systems. However, they are not a substitute for detailed surveys of those systems. Users of this method should consider that the method may under-score or over-score the site that’s assessed, especially when the site is not a typical fen (i.e. a sedge meadow could score lower than fens, but in-fact be a relatively high quality sedge meadow). This assessment can be used throughout most of the spring, summer and fall period, however the ideal “index period” would be from late May through early October when native plant communities, as well as invasive species, are most apparent.

Iowa State Government Technology Assessment Project, 1995

The State of Iowa is conducting an as5essment of Information Technology (IT) in the Executive Branch. The purpose of this assessment is to gather data on costs, applications, systems, utilization, operations, hardware assets, administration and activities associated with the provision of IT services. To accomplish this, two leading technology vendors conducted an intense assessment. These vendors, Integrated System Solutions Corporation (ISSC), and Electronic Data Systems (EDS) analyzed extensive data provided by the various ·agencies and conducted on-site interviews during the week of November 13, 1995. Additionally, in the first week of December, the American Federation of State, County, and Municipal Employees (AFSCME) Iowa Council 61 sponsored an assessment. These assessments are included as appendices B, C, and D to this report.
