Design and Construction Procedures for Concrete Overlay and Widening of Existing Pavements, September 2005

State Highway Departments and local street and road agencies are currently faced with aging highway systems and a need to extend the life of some of the pavements. The agency engineer should have the opportunity to explore the use of multiple surface types in the selection of a preferred rehabilitation strategy. This study was designed to look at the portland cement concrete overlay alternative and especially the design of overlays for existing composite (portland cement and asphaltic cement concrete) pavements. Existing design procedures for portland cement concrete overlays deal primarily with an existing asphaltic concrete pavement with an underlying granular base or stabilized base. This study reviewed those design methods and moved to the development of a design for overlays of composite pavements. It deals directly with existing portland cement concrete pavements that have been overlaid with successive asphaltic concrete overlays and are in need of another overlay due to poor performance of the existing surface. The results of this study provide the engineer with a way to use existing deflection technology coupled with materials testing and a combination of existing overlay design methods to determine the design thickness of the portland cement concrete overlay. The design methodology provides guidance for the engineer, from the evaluation of the existing pavement condition through the construction of the overlay. It also provides a structural analysis of various joint and widening patterns on the performance of such designs. This work provides the engineer with a portland cement concrete overlay solution to composite pavements or conventional asphaltic concrete pavements that are in need of surface rehabilitation.

Final Report for the Iowa Livestock Industry Waste Characterization and Methane Recovery Information Dissemination Project, 2003

The Iowa livestock industry generates large quantities of manure and other organic residues; composed of feces, urine, bedding material, waste feed, dilution water, and mortalities. Often viewed as a waste material, little has been done to characterize and determine the usefulness of this resource. The Iowa Department of Natural Resources initiated the process to assess in detail the manure resource and the potential utilization of this resource through anaerobic digestion coupled with energy recovery. Many of the pieces required to assess the manure resource already exist, albeit in disparate forms and locations. This study began by interpreting and integrating existing Federal, State, ISU studies, and other sources of livestock numbers, housing, and management information. With these data, models were analyzed to determine energy production and economic feasibility of energy recovery using anaerobic digestion facilities on livestock faxms. Having these data individual facilities and clusters that appear economically feasible can be identified specifically through the use of a GIs system for further investigation. Also livestock facilities and clusters of facilities with high methane recovery potential can be the focus of targeted educational programs through Cooperative Extension network and other outreach networks, providing a more intensive counterpoint to broadly based educational efforts.

Design Guide and Construction Specifications for National Pollutant Discharge Elimination System (NPDES) Site Runoff Control, 2006

According to the 1972 Clean Water Act, the Environmental Protection Agency (EPA) established a set of regulations for the National Pollutant Discharge Elimination System (NPDES). The purpose of these regulations is to reduce pollution of the nation’s waterways. In addition to other pollutants, the NPDES regulates stormwater discharges associated with industrial activities, municipal storm sewer systems, and construction sites. Phase II of the NPDES stormwater regulations, which went into effect in Iowa in 2003, applies to construction activities that disturb more than one acre of ground. The regulations also require certain communities with Municipal Separate Storm Sewer Systems (MS4) to perform education, inspection, and regulation activities to reduce stormwater pollution within their communities. Iowa does not currently have a resource to provide guidance on the stormwater regulations to contractors, designers, engineers, and municipal staff. The Statewide Urban Design and Specifications (SUDAS) manuals are widely accepted as the statewide standard for public improvements. The SUDAS Design manual currently contains a brief chapter (Chapter 7) on erosion and sediment control; however, it is outdated, and Phase II of the NPDES stormwater regulations is not discussed. In response to the need for guidance, this chapter was completely rewritten. It now escribes the need for erosion and sediment control and explains the NPDES stormwater regulations. It provides information for the development and completion of Stormwater Pollution Prevention Plans (SWPPPs) that comply with the stormwater regulations, as well as the proper design and implementation of 28 different erosion and sediment control practices. In addition to the design chapter, this project also updated a section in the SUDAS Specifications manual (Section 9040), which describes the proper materials and methods of construction for the erosion and sediment control practices.

The Construction Of Ethical Competence In The Perception Of Primary Care Nurses


The study intended to understand the perception of nurses of Primary Care Services about the construction of ethical competence on their formation and practices. This is a qualitative study, with an interpretative phenomenological approach and interviews with ten nurses of the community health services of Porto Alegre, RS. The results showed that the interviewed professionals had already experienced situations with ethical conflicts and knew what ethical competence means. The central themes point out three fundamental issues in the construction of the ethical competence: personal values, education and practice. Taking into account that ethical competence is in permanent construction, the study shows the importance to promote organizational and educational activities in a transversal manner, as a tool to cope the moral stress and contribute in improving the quality of care in the primary health attention.


Quand la pornographie fait violence... réflexions sur les méfaits de la pornographie sur la construction de la sexualité adolescente

Dans notre pratique auprès des adolescents engagés dans des agirs sexuels violents, la consommation de pornographie est fréquemment convoquée dans le parcours de ces sujets à la découverte de la sexualité. Si bien sûr, tous les adolescents qui visionnent ces images ne commettent pas de tels actes, ce constat préoccupant nous invite à nous interroger sur les effets ou plutôt les méfaits de la pornographie sur l'investissement du corps sexué et sur la construction de la sexualité. Outre une réflexion sur l'impact de l'image dans son caractère obscène et à la suite des travaux de G. Bonnet (2003, Le Défi à la pudeur. Quand la pornographie devient l'initiation sexuelle des jeunes), nous montrerons en quoi la pornographie constitue une forme de violence, parfois jusqu'au traumatisme. Ce danger auquel les adolescents sont (sur)exposés, notamment par le biais d'Internet, pourrait en effet favoriser un clivage (que nous retrouvons systématiquement dans la problématique des violences sexuelles) entre corps érotique et corps sexué. La consommation de pornographie s'apparenterait davantage à l'incorporation de la sexualité génitale marquant ainsi l'échec de l'introjection de la génitalité au moment de l'adolescence. Ne devient-elle pas alors un ersatz de la pulsion de mort ? en tant qu'elle isole le sujet dans une activité auto-pseudo-érotique, retirant à la sexualité sa fonction de lien et par là même ouvrant le champ au déchaînement de toutes formes de violence.
