09028-014 Tributary B to Fourmile Creek Final Report

The city of Ankeny is submitting this WIRB application for development of green urban stormwater practices on city and private property in the Fourmile Creek watershed. The stormwater project proposed includes stream restoration of the SE Tributary to Fourmile Creek (Tributary B), including weirs, bank shaping, toe protection, trees, and native plantings. The project also includes the creation of a native buffer along the stream channel in the city’s Summerbrook Park, installing four native planting beds, installing a pervious surface trail, installing a series of rain gardens/biorentention cells, and installing educational signage. Polk County Soil and Water Conservation District has committed $17,000 towards the native buffer and rain garden/biorentention cell. The city of Ankeny was also awarded a $100,000 I-JOBS grant from IDNR to complete the stormwater retrofit practices. The largest component of this project is public education. Our vision for this project is to take the entire 281 acre watershed and address it as a whole. We want to make a collaborative watershed that not only addresses the water entering the stream channel through adjacent properties, but takes each individual parcel within the watershed and strives to reduce contributions to the stormwater system. The stormwater issues of concern for Tributary B include stormwater volume, sediment, and nutrients. The stream restoration, best management practices (BMP) at Summerbrook Park, and BMPs on private property should help decrease the volume of stormwater and reduce the amount of sediment and nutrients that enter Tributary B and ultimately Fourmile Creek.

Iowa's Barriers to Prenatal Care Project, August 2013

The findings in this summary are based on the Iowa Barriers to Prenatal Care project. Ongoing since 1991, the purpose of this project is to obtain brief, accurate information about women delivering babies in Iowa hospitals. Specifically, the project seeks to learn about women’s experiences getting prenatal or delivery care during their current pregnancy. Other information is included which may be pertinent to health planners or those concerned with the systematic development of health care services. This project is a cooperative venture of all of Iowa’s maternity hospitals, the University of Northern Iowa Center for Social and Behavioral Research, and the Iowa Department of Public Health. The Robert Wood Johnson Foundation funded the first three years of this project. The current funding is provided by the Iowa Department of Public Health. The Director is Dr. Mary Losch, University of Northern Iowa Center for Social and Behavioral Research. The Coordinator for the project is Rodney Muilenburg. The questionnaire is distributed to nearly ninety maternity hospitals across the state of Iowa. Nursing staff or those responsible for obtaining birth certificate information in the obstetrics unit are responsible for approaching all birth mothers prior to dismissal and requesting their participation in the study. The questionnaire takes approximately ten minutes to complete. Completed questionnaires are returned to the University of Northern Iowa Center for Social and Behavioral Research for data entry and analysis. Returns are made monthly, weekly, or biweekly depending on the number of births per week in a given hospital. Except in the case of a mother who is too ill to complete the questionnaire, all mothers are eligible to be recruited for participation. The present yearly report includes an analysis of large Iowa cities, African American mothers, and a trend analysis of the last ten years. Also presented in this report is a frequency analysis of all variables included in the 2012 questionnaire. Unless otherwise noted, all entries reflect percentages. Please note that because percentages were rounded, total values may not equal 100%. Data presented are based upon 2012 questionnaires received to date (n = 23,674). All analyses reflect unweighted percentages of those responding.

Local model predictive control experiences with differential driven wheeled mobile robots

This work extends a previously developed research concerning about the use of local model predictive control in differential driven mobile robots. Hence, experimental results are presented as a way to improve the methodology by considering aspects as trajectory accuracy and time performance. In this sense, the cost function and the prediction horizon are important aspects to be considered. The aim of the present work is to test the control method by measuring trajectory tracking accuracy and time performance. Moreover, strategies for the integration with perception system and path planning are briefly introduced. In this sense, monocular image data can be used to plan safety trajectories by using goal attraction potential fields

Mobile robot experimental modeling and control strategies using sensor fusion

This research work deals with the problem of modeling and design of low level speed controller for the mobile robot PRIM. The main objective is to develop an effective educational, and research tool. On one hand, the interests in using the open mobile platform PRIM consist in integrating several highly related subjects to the automatic control theory in an educational context, by embracing the subjects of communications, signal processing, sensor fusion and hardware design, amongst others. On the other hand, the idea is to implement useful navigation strategies such that the robot can be served as a mobile multimedia information point. It is in this context, when navigation strategies are oriented to goal achievement, that a local model predictive control is attained. Hence, such studies are presented as a very interesting control strategy in order to develop the future capabilities of the system. In this context the research developed includes the visual information as a meaningful source that allows detecting the obstacle position coordinates as well as planning the free obstacle trajectory that should be reached by the robot

Optimizing Pavement Base, Subbase, and Subgrade Layers for Cost and Performance of Local Roads, TR-640

This report is one of two products for this project with the other being a design guide. This report describes test results and comparative analysis from 16 different portland cement concrete (PCC) pavement sites on local city and county roads in Iowa. At each site the surface conditions of the pavement (i.e., crack survey) and foundation layer strength, stiffness, and hydraulic conductivity properties were documented. The field test results were used to calculate in situ parameters used in pavement design per SUDAS and AASHTO (1993) design methodologies. Overall, the results of this study demonstrate how in situ and lab testing can be used to assess the support conditions and design values for pavement foundation layers and how the measurements compare to the assumed design values. The measurements show that in Iowa, a wide range of pavement conditions and foundation layer support values exist. The calculated design input values for the test sites (modulus of subgrade reaction, coefficient of drainage, and loss of support) were found to be different than typically assumed. This finding was true for the full range of materials tested. The findings of this study support the recommendation to incorporate field testing as part of the process to field verify pavement design values and to consider the foundation as a design element in the pavement system. Recommendations are provided in the form of a simple matrix for alternative foundation treatment options if the existing foundation materials do not meet the design intent. The PCI prediction model developed from multi-variate analysis in this study demonstrated a link between pavement foundation conditions and PCI. The model analysis shows that by measuring properties of the pavement foundation, the engineer will be able to predict long term performance with higher reliability than by considering age alone. This prediction can be used as motivation to then control the engineering properties of the pavement foundation for new or re-constructed PCC pavements to achieve some desired level of performance (i.e., PCI) with time.

A randomized trial of glutamine and antioxidants in critically ill patients.

BACKGROUND: Critically ill patients have considerable oxidative stress. Glutamine and antioxidant supplementation may offer therapeutic benefit, although current data are conflicting. METHODS: In this blinded 2-by-2 factorial trial, we randomly assigned 1223 critically ill adults in 40 intensive care units (ICUs) in Canada, the United States, and Europe who had multiorgan failure and were receiving mechanical ventilation to receive supplements of glutamine, antioxidants, both, or placebo. Supplements were started within 24 hours after admission to the ICU and were provided both intravenously and enterally. The primary outcome was 28-day mortality. Because of the interim-analysis plan, a P value of less than 0.044 at the final analysis was considered to indicate statistical significance. RESULTS: There was a trend toward increased mortality at 28 days among patients who received glutamine as compared with those who did not receive glutamine (32.4% vs. 27.2%; adjusted odds ratio, 1.28; 95% confidence interval [CI], 1.00 to 1.64; P=0.05). In-hospital mortality and mortality at 6 months were significantly higher among those who received glutamine than among those who did not. Glutamine had no effect on rates of organ failure or infectious complications. Antioxidants had no effect on 28-day mortality (30.8%, vs. 28.8% with no antioxidants; adjusted odds ratio, 1.09; 95% CI, 0.86 to 1.40; P=0.48) or any other secondary end point. There were no differences among the groups with respect to serious adverse events (P=0.83). CONCLUSIONS: Early provision of glutamine or antioxidants did not improve clinical outcomes, and glutamine was associated with an increase in mortality among critically ill patients with multiorgan failure.

Diseño e implementación de una Web dinámica como herramienta para el control de obras en base al coste del proceso de construcción

En la actualidad estamos sufriendo una situación de crisis económica de dimensiones desproporcionadas e inusuales, la cual está obligando a todas las empresas a globalizar en mayor medida el ámbito de actuación de sus negocios, por lo que muchas empresas que trabajaban exclusivamente en el ámbito local o nacional han tenido que expandirse hacia el exterior. Este hecho, añadido a la fortísima competencia existente en el mercado, obligará a todas estas empresas a tener que controlar en mayor medida la actividad productiva, y a hacerlo utilizando tecnologías que faciliten el flujo de la información dentro de la empresa, hagan que la distancia no sea un problema para la transmisión de esa información, y con las que todos los usuarios manejen los mismos datos. El sector de la construcción es uno de los más castigados por la citada crisis, y probablemente uno de los más retrasados en lo que respecta a utilización de Tecnologías de la Información y la Comunicación. El objetivo principal de este trabajo es el diseño e implementación de una web dinámica como herramienta para medir la eficiencia en el control de la actividad productiva de una empresa constructora. La manera de medir esta eficiencia será mediante la comparación mensual de los costes previstos para las diferentes obras que deba ejecutar la empresa (los cuales podemos llamar estándar) y los que se vayan produciendo realmente. La herramienta diseñada podría ir aumentando su utilidad si, añadiendo módulos mediante la ampliación de la base de datos y diseñando las pertinentes nuevas páginas web para el sitio, se usa también para otros menesteres además del control de la actividad productiva por comparación entre costes previstos y reales. Es decir, que se podría llegar a gestionar la información de todas las actividades de la empresa (compras, recursos humanos, contabilidad, gestión de calidad, etc.). Por lo tanto, una web dinámica como la expuesta en el trabajo podría servir como semilla para el desarrollo de un ERP (Enterprise Resource Planning).

Determination of Flood Dischard Characteristics of Small Drainage Areas, HR-3, Progress Report, 1960

Project HR-3 of the Iowa Highway Research Board has been active since October 1, 1950. The project objective is the determination of flood discharge characteristics of small drainage areas. Funds for the project amount to $10,000 per year of which, by cooperative agreement, the Highway Commission and the U. S. Geological Survey each furnish $5,000. Previous reports have explained the set-up of the project and these explanations will not be repeated in this report.

A Fifteen Year Performance Summary of Fibrous PC Concrete Overlay Research in Greene County, Iowa, HR-165, 1989

The Greene County, Iowa, overlay project, completed in October 1973, was evaluated in October 1978, after five years in October 1983, after ten years and most recently in October 1988 after fifteen years of service. The 33 fibrous concrete sections, four CRCP sections, two mesh reinforced and two plain concrete sections with doweled reinforcement were rated relative to each other on a scale of 0 to 100. The rating was conducted by original members of the Project Planning Committee, Iowa DOT, Iowa County, Federal Highway Administration and industry representatives. In all, there were 23, 25 and 17 representatives who rated the project in 1978, 1983 and 1988 respectively. The 23, 25 or 17 values were then averaged to provide a final rating number for each section or variable. All experimental overlay sections had performed quite well in the period from five through 15 years, experiencing only limited additional deterioration.

Survey No. 1, Fibrous Concrete Resurfacing Greene County, Iowa, HR-165, 1974

The three miles of fibrous concrete resurfacing in Greene County, Iowa were placed in September and early October, 1973. It was recognized in advance that cracking and other performance characteristics of the fibrous concrete sections and of the central sections would be major factors in the evaluation of the project. A low level aerial survey was made of the old pavement. During construction of the resurfacing, the aerial survey was checked to insure that cracks in the old pavement were referenced to the 100 ft. station marks placed in the resurfacing. The crack survey recorded herein was made in March and April, 1974. Those cracks in the resurfacing that are reflections of cracks in the underlying slab are identified by /\ marks. Observations (not detailed crack surveys) made in June, 1974 indicate that further cracking of the resurfacing has occurred since this report was prepared. In particular, there appears to be same additional longitudinal cracking over the widening joints.

A Ten Year Performance Summary of Fibrous PC Concrete Overlay Research in Greene County, Iowa, HR-165, 1984

The Greene County, Iowa, overlay project, completed in October, 1973, was evaluated in October, 1978, after five years of service and most recently in October, 1983, after ten years of service. The 33 fibrous concrete sections, four CRCP sections, two mesh reinforced and two plain concrete sections with doweled reinforcement were rated relative to each other on a scale of 0 to 100. The rating was conducted by original members of the Project Planning Committee, Iowa DOT, Iowa County, Federal Highway Administration, University of Illinois and industry representatives. In all, there were 23 and 24 representatives who rated the project in 1978 and 1983 respectively. The 23 or 24 values were then averaged to provide a final rating number for each section or variable. All experimental overlay sections had performed quite well in the period from five through 10 years, experiencing only limited additional deterioration. Based upon this relatively good performance through 10 years, the sections will be maintained for further research with another evaluation at 15 years. The 4" thick nonfibrous mesh reinforced continuous reinforced concrete pavement overlay sections provided the best performance in this research project. Another nonfibrous 5" thick bar reinforced overlay section performed almost as well. The best performance of a fibrous reinforced concrete section was obtained with 160 pounds of fiber per cubic yard.
