Final Report for Research Project HR-181, Macadam Base Shoulders, September 1981

Highway safety and pavement performance can be directly influenced by the type of shoulders that are constructed. Shoulder design alternatives have always been rather limited. Moreover, the use of some of the alternatives has always been restricted by funding limitations. This research project seeks to explore the use of modified macadam base construction for shoulders. This type of shoulder design could offer the designer another option when paved or stabilized shoulders are being considered. Macadam base construction has in the past been shown to be quite strong and free draining. Two macadam base shoulder designs were developed and constructed for this research project. A new roadway embankment and P.C.C. pavement were constructed on a section of US 6 east of Adel in Dallas County. The macadam base shoulders were constructed adjacent to the pavement as part of the project. The north shoulder was finished with a choke stone course and bituminous surface treatment and the south shoulder was finished with a two (2) inch layer of Type B Class I1 asphalt concrete. Macadam stone base shoulders can be built with relatively minor construction problems with comparable strength and less cost than asphalt treated base shoulders. The macadam stone base shoulders have performed well with very little maintenance necessary. The improved drainage substantially reduces deterioration of the pavement joints.

La caverna de Josep Palau i Fabre (1952-1969): teatre versus al·legoria filosòfica per a representar i impedir el final trà gic i fosc del lluminós art de pensar.

What is the use of performing the myth of the cave from book VII of the Republic by Plato? Josep Palau i Fabre, considers that, in Plato's dialogues, the speakers are mere instruments at the service of his dialectical goal. The aim of this article is to show how, by turning the myth into a tragedy and also by relying on Heraclitus's conflict or war of opposites, the playwright succeeds in favoring a sort of thought which is not one-sided or univocal. On the contrary, in Palau i Fabre's La Caverna, the tragic hero, that is, the released prisoner transformed by the light of Reality and finally killed by his "cavemates" -after having been imprisoned again and having tried to rescue them from their ignorance or shadows-, still leaves to them his powerful experience of the agonistikos thought, which might bear fruit in their life to come.

Gorgias y el final del Ion de Eurípides

En las últimas décadas, los estudios de narratología han subrayado la función estructuradora que cumple el final de una obra en el conjunto de la trama, advirtiendo que, desde la lógica de una narración que progresa hacia un final, es éste el que da sentido al proceso. En tragedia griega el fenómeno resulta especialmente sensible en Sófocles, que ha diseñado sus propias pautas genéricas, las que mejor responden a nuestro concepto de intriga conclusiva. Eurípides resulta desde esta perspectiva un radical innovador del género trágico , pues el final de la performance es, con frecuencia, una pausa arbitraria en la acción. F.M. Dunn ha estudiado minuciosamente cómo esa suspensión del final de la tragedia en Eurípides viene acompañada de una «formal rhetoric of closure» (p. 7), consistente en una serie de recursos como el deus ex machina , el relato etiológico o profecía final, el discurso de aquiesciencia y la declaración de salida del coro («Closing Gestures», pp. 13-64). Tales mecanismos convencionales, afirma, son exteriores a la acción dramática y zanjan el argumento al tiempo que lo abren a soluciones múltiples, anticipando el camino a la novela.

Malaria chemoprophylaxis: what do the travelers choose, and how does pretravel consultation influence their final decision.

Three different drugs (mefloquine, atovaquone/proguanil, doxycycline) are recommended for malaria chemoprophylaxis, each with approximately the same efficacy but various adverse event profiles, regimens, and prices. We investigated which medication the travelers would have chosen on the basis of written evidence-based information and the impact that pretravel consultation had on their decision. A prospective study was performed in a travel clinic and private practice, and 1073 travelers were included; 45% chose mefloquine (Lariam or Mephaquine), 21% atovaquone/proguanil (Malarone), 18% doxycycline (Supracycline), 5% "no prophylaxis," and 11% "do not know." Lariam was principally chosen because of prior experience (38%), Mephaquine because of low price (34%), and doxycycline and Malarone because of the profile of adverse events (55% and 43%, respectively). Based on objective written information, travelers most frequently chose mefloquine for chemoprophylaxis. This suggests that evidence-based information weighs more heavily than negative publicity. Taking into account the perspective of the user should improve appropriateness of the pretravel advice.

Evaluating the Effectiveness of Red Light Running Camera Enforcement in Cedar Rapids and Developing Guidelines For Selection and use of Red Light Running Countermeasures, Midwest Transportation Consortium, Final Report November 2011.

Red light running (RLR) is a problem in the US that has resulted in 165,000 injuries and 907 fatalities annually. In Iowa, RLR-related crashes make up 24.5 percent of all crashes and account for 31.7 percent of fatal and major injury crashes at signalized intersections. RLR crashes are a safety concern due to the increased likelihood of injury compared to other types of crashes. One tool used to combat red light running is automated enforcement in the form of RLR cameras. Automated enforcement, while effective, is often controversial. Cedar Rapids, Iowa installed RLR and speeding cameras at seven intersections across the city. The intersections were chosen based on crash rates and whether cameras could feasibly be placed at the intersection approaches. The cameras were placed starting in February 2010 with the last one becoming operational in December 2010. An analysis of the effect of the cameras on safety at these intersections was determined prudent in helping to justify the installation and effectiveness of the cameras. The objective of this research was to assess the safety effectiveness of the RLR program that has been implemented in Cedar Rapids. This was accomplished by analyzing data to determine changes in the following metrics: ï‚· Reductions in red light violation rates based on overall changes, time of day changes, and changes by lane ï‚· Effectiveness of the cameras over time ï‚· Time in which those running the red light enter the intersection ï‚· Changes in the average headway between vehicles entering the intersection

Debris Mitigation Methods for Bridge Piers, Final Repory, June 2012

Debris accumulation on bridge piers is an on-going national problem that can obstruct the waterway openings at bridges and result in significant erosion of stream banks and scour at abutments and piers. In some cases, the accumulation of debris can adversely affect the operation of the waterway opening or cause failure of the structure. In addition, removal of debris accumulation is difficult, time consuming, and expensive for maintenance programs. This research involves a literature search of publications, products, and pier design recommendations that provide a cost effective method to mitigate debris accumulation at bridges. In addition, a nationwide survey was conducted to determine the state-of-the-practice and the results are presented within.

Pavement Surface on Macadam Base: Adair County Final Report, Iowa Highway Reserach Board Project HR-209

The quality and availability of aggregate for pc concrete stone varies across Iowa. Southwest Iowa is one area of the state that is short of quality aggregates. The concrete stone generally available in the area is limestone from the Argentine or Winterset ledges with an overburden of up to 150 feet. This concrete stone is classified as Class 1 durability and is susceptible to 'ID"-cracking. In addition, the general engineering soil classification rates the soils of southwest Iowa as having the poorest subgrade bearing characteristics in the state. 1 The combination of poor soils and low quality aggregate has contributed to premature deterioration of many miles of portland cement concrete pavement. Research project HR-209 was initiated in 1979 to explore alternative construction methods that may produce better pavements for southwest Iowa.
