Stratigraphical discontinuities, tropical landscape evolution and soil distribution relationships in a case study in SE-Brazil

On a regional summit surface in the county of Piracicaba (SP) within the Peripheric Depression of São Paulo, formed of discontinued flattened tops, there is an abrupt transition between a Typic Hapludox and a Kandiudalfic Eutrudox, together with two stoneline layers. Using stratigraphical, mineralogical, and cartographic studies, this transition and the soil distribution of this surface were studied, correlating them with the different parent materials and the morphoclimatic model of landscape evolution in Southeastern Brazil. The Typic Hapludox was formed on a sandy Cenozoic deposit (Q) that overlies a pellitic deposit of the Iratí formation (Pi), representing a regional erosive discordance. Westwards to the Piracicaba River, this sequence is interrupted by a diabase sill overlain by a red clayey material which gave origin to the Kandiudalfic Eutrudox. Two post-Permian depositional events were identified by the two stonelines and stratigraphical discontinuities. The first event generated the deposition of a sandy sediment in the form of levelled alveoluses on regional barriers, most of these formed by dikes and diabase sills, probably during a drier phase. The second depositional event, leading to the deposition of the red clay was probably the dissection of the previously formed pediplane during a humid climate, followed by another pedimentation process during a later, drier period.

Fibrous P.C. Concrete Overlay Research Green County, Iowa, December 1978

The Greene County, Iowa overlay project, completed in October 1973, was inspected on October 16 & 17, 1978 After five 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 t o 100. The rating was conducted by the original members of the Project Planning Committee, Iowa DOT, Iowa Counties, Federal Highway Administration, University of Illinois and industry representatives . In all , there were 23 representatives who rated this project . The 23 values were then averaged to provide a final rating number for each section. The highest panel rating (90) was assigned to the 5-inch thick , deformed barre in forced PCC sections ; an 86t o a 3-inch thick , 160 lbs. of fiber and 600 lbs . of cement on a partial bonded surface ; an 84 to the 4-inch CRC with elastic joints (bonded) and an 84 to a 4-inch mesh reinforce section. One of the major factors influencing performance appears t o be the thickness. In the fibrous concrete overlay, The greatest influences appears t o be the fiber content. Overlay Sections containing 160 1b/yd3 of Fiber are, in almost all cases , outperforming those c o n t a i n i n g 60 or 100. It is obvious at This time meth at the 3-inch thick fibrous concrete overlays are, in general, out performing the 2-inch thick sections. The performance of the fibrous concrete the overlay appears to be favorably influenced by: (1) The use of higher a spectra fiber (0.025 x 2.5 i n c h e s ) v e r s u s (0.010 x 0.022 x 1.0 inches) (2) The use of a lower cement c o n t e n t ( 600 versus 750 1b/yd3) However, The set less well defined and the improvements in overlay performance attributed to high aspect ratio fibers and low cement contents.

Iowa Historic Property Study: Iowana Farms Milk Company, 1416 State Street, City of Bettendorf, Scott County, Iowa, 2012

The Iowana Farms Milk Company factory building was considered to retain sufficient integrity and possess sufficient significance to be considered eligible for the National Register of Historic Places under Criteria A and C for its historical and architectural significance in the Bettendorf community. The Iowana Farms Milk Company was an important early to mid-twentieth-century business in Bettendorf, and was among the few that was not owned or operated by the Bettendorf Company. It was a strong and thriving business for many years, and its products were well known in the Quad Cities region. The importance of this property becomes even more significant when one considers that most of the buildings once associated with the actual Bettendorf Company, which was undeniably the most important business and industry in town, are now gone. As a result, the Iowana Farms Milk Company factory building was a physical vestige of the once-thriving commercial industries that made Bettendorf into a city in the twentieth century. This property was further significant for its representation of the evolution of the dairy industry in the twentieth century from farm to factory production. It also reflected the changes to the industry based on scientific discoveries, mechanical innovations, and governmental regulations related to improved sanitation and the pure milk movement. The Iowana Farms Milk Company represented a model plant for the time, and the marketing strategies it employed followed the trends of the industry. The Iowana Farms Milk Company plant had to be removed to make room for a new I-74 bridge over the Mississippi River at Bettendorf. The construction of the new bridge also required removal of the historic Iowa-Illinois Memorial Bridge. The documentation reported herein and for that of the Iowa-Illinois Memorial Bridge fulfills the requirements of the Memorandum of Agreement regarding the removal of these historic properties.

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.

Health consultation : Iowa City former manufactured gas plant site, 505 Burlington Street, Iowa City, Johnson County, Iowa EPA facility ID: IAD984591172 (2006)

The United States Environmental Protection Agency (EPA) has requested the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program to evaluate the health impacts of the proposed remedial strategy to be implemented at the Iowa City Former Manufactured Gas Plant Site (FMGP). The proposed remedial strategy to be implemented incorporates the following: 1) access restrictions through the continued operation of the Iowa-Illinois Manor and restriction on any future water well installation through continued implementation of a local environmental covenant; 2) previous site decommissioning activities that have restricted access to site contaminants; and 3) continued monitoring of the groundwater to ensure that contaminant levels in groundwater remain the same or are declining in concentration. This health consultation addresses potential health risks to people from exposure to the soil and vapors within the property. The information in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations.

L’archivage numérique des projets « Europan » comme situation d’analyse scientifique du concours d’idées en architecture

Il existe somme toute peu de théories du projet offrant une modélisation construite à partir de la complexité et de la diversité du projet d’architecture. Pourtant,certaines situations rassemblant parfois plusieurs dizaines de projets s’offrent d’elles-mêmes comme des situations comparatives et expérimentales : les concours d’architecture, d’urbanisme et de paysage. Le Laboratoire d’étude de l’architecture potentielle de l’Université de Montréal (Aménagement), après avoir développé un système d’archivage numérique des concours canadiens, a entrepris, avec le soutien du Groupement d’intérêt public « Europe des projets architecturaux et urbains », de développer la base de données documentaire des concours d’idées Europan. Au-delà des questions d’archivage numérique, se profilent clairement des possibilités de théorisation s’appuyant sur les logiques d’une base de données, en particulier sur la constitution du diagramme entités et relations, modélisation indispensable à sa traduction informatique. Cette recherche entreprend une première mise à jour de ces éléments conceptuels et tend à montrer que la base de données est un véritable modèle théorique du projet ouvrant sur de nouvelles avenues de recherche et de connaissance.

L’architecture engagée du «Case Study House Program» de la revue Arts and Architecture de 1945 – 1966 : une confluence génératrice

La conception architecturale du logis, individuel ou collectif, est un défi majeur pour les architectes depuis l'avènement de la modernité. Au début du 21ième siècle, la multiplicité des conditions démographiques et celle de la mobilité des personnes sous-tendent la complexité de l'élaboration de prototypes ou de modèles d'habitation. Que peut-on apprendre des expériences menées dans ce domaine après la seconde guerre mondiale aux États-Unis ? Ce mémoire de maîtrise est consacré à l'étude d’un cas particulier celui du programme de création architecturale réalisée en Californie de 1945 à 1966, connu sous le nom de : «Case Study House Program». Ce programme, dirigé par John Entenza, éditeur de la revue Arts and Architecture, rassemblait de nombreux architectes dont les plus célèbres sont Charles et Ray Eames, Richard Neutra, Craig Ellwood et Pierre Koenig, tous auteurs de maisons modernes devenues oeuvres canoniques dans l’histoire de l’architecture. L'analyse détaillé de ce cas et de ses retombées devrait permettre de mieux cerner les aspects suivants: la portée critique du CSHP (case study house program) qui s'opposait aux modèles dominants du marché immobilier, modèles généralement inspirés de styles traditionnels; le potentiel et les limites d'une telle démarche face à la demande sociale; la dimension anticipatrice des propositions du CSHP pour la conception de logis mieux adaptés aux besoins du 21ième siècle, en particulier ceux qui découlent des changements démographiques et de la mobilité géographiques des personnes; la valeur d'exemple du CSHP pour mieux comprendre les fondements de la résistance du public aux innovations architecturales, autant du point de vue technique que du point de vue esthétique.

La travesía obsoleta: la indefensión del consumidor
