This is YOUR Highway Commission,1968

Before the Iowa Department of Transportation (DOT) was established by legislation in July 1974, there were several state agencies that handled the tasks that are now the responsibility of an integrated, multimodal Iowa DOT. Among those agencies was the Iowa State Highway Commission (IHC). You are invited to read a brief history of the Iowa DOT here:http://www.iowadot.gov/about/organizationalhistory.htm The IHC operated as an independent state agency between 1913 and 1974. In 1968, the IHC created and released This is YOUR Highway Commission, a 24 ½- minute film that showcased the responsibilities and functions of the IHC. The narrator describes the activities of various offices and employees, and explains how those activities benefited Iowa’s citizens and motorists. The film journeys through all areas of IHC responsibility to Iowa’s roadways, including administration, planning, design, bidding, right of way, materials, construction, maintenance and facilities. As part of the Iowa DOT’s effort to preserve and archive its historical resources, the original 16mm film was professionally cleaned, restored and digitized so that it could be made available via this website. The Iowa DOT is currently researching and compiling information necessary to prepare detailed biographies of the IHC employees identified in the film. Included in each biography will be still frames taken from the film, as well as other images from the Iowa DOT’s archives. This more comprehensive description of the film will be available in the future. In the meantime, below is a list of the IHC employees who have been identified. The list is arranged in the order in which each employee first appears in the film. There remain numerous unidentified employees in the film, and the Iowa DOT would greatly appreciate any assistance in identifying them. If you recognize an IHC employee in the film who is not on this list, please contactbeth.collins@dot.iowa.gov with any information you feel would be useful.

Qualidade da semente e senescência de genótipos de soja sob dois níveis de infestação de percevejos (Pentatomidae)

Este trabalho objetivou estudar a resistência de duas linhagens de soja, do programa de melhoramento do sabor da Universidade Federal de Viçosa, MG, cultivadas sob dois níveis de infestação de percevejos, em comparação com três cultivares de soja. Os genótipos estudados foram: CR-1, CR-3, Cristalina (linhagem paterna), Davis (padrão de suscetibilidade) e IAC-100 (padrão de resistência). CR-1, CR-3, Davis e Cristalina, sob baixa infestação, produziram porcentagens de sementes normais semelhantes entre si (57%), e inferiores às de IAC-100 (77%). Sob alta infestação, CR-1, CR-3 e Cristalina produziram percentagens de sementes normais semelhantes entre si (22%) e inferiores às de Davis (43%) e IAC-100 (59%). Todos os genótipos apresentaram baixo grau de retenção foliar (menos que 6%) quando cultivados sob baixa infestação, mas sob alta infestação, a CR-1 e IAC-100 apresentaram menores porcentagens de retenção foliar (menos que 5%), seguida por Davis e CR-3 (6-20%) e Cristalina (21-40%). CR-1, IAC-100 e Davis não apresentaram plantas com caule verde sob baixa infestação, ao contrário do que foi registrado com CR-3 (3,6%) e Cristalina (11%). IAC-100, CR-1 e Davis apresentaram menores porcentagens de plantas com caule verde (6,4, 10,3 e 18,3%, respectivamente) que CR-3 (64,8%) e Cristalina (77,3%).

Genèse de la recherche académique nord-américaine sur les expériences de mort imminente. L'exemple des recherches menées par Russel Noyes, psychiatre, de 1967 à 1977

La présente thèse analyse les facteurs expliquant l'attrait académique pour la Near-Death Experience (NDE) aux Etats-Unis. À travers l'étude d'un acteur clé, Russell Noyés, la thèse démontre que l'expérience de mort imminente est devenue pertinente grâce aux psychiatres et aux psychologues qui lui ont octroyé une qualité clinique et thérapeutique. Afin de reconstruire les fondements académiques de l'intérêt pour l'étude de la mort, de l'expérience de la mort et de la mort imminente en psychiatrie dans les années 1960-70, la méthode employée est celle d'une enquête historique qui combine une approche empirique avec une génétique de récit. - The dissertation analyses the factors explaining the emergence of the Near- Death Experience (NDE) as a research topic in the disciplines of psychology and psychiatry in the United States. The study of a key actor, Russell Noyes, will demonstrate how the experience of near-death became relevant through the work of psychiatrists and psychologists who attributed a clinical and therapeutical quality to it. In order to retrace the academic foundations of the research on death, the experience of dying and near-death, during the 60s and 70s, this dissertation applies a historical method, which combines an empirical approach with a genetic of narratives.

Correlação entre medidas paramétricas e não-paramétricas de estabilidade em soja

Foram avaliadas a adaptabilidade e a estabilidade de genótipos de soja (Glycine max L.) segundo a metodologia clássica de Eberhart e Russell e a estabilidade dos mesmos genótipos pela metodologia não-paramétrica de Huhn. Os experimentos foram conduzidos no delineamento em blocos casualizados, com três repetições e com 30 tratamentos (genótipos de soja), durante três anos consecutivos. As parcelas experimentais foram constituídas por quatro linhas de cultivo, espaçadas de 0,50 m e com densidade de 25 plantas por metro linear. Como área útil, foram tomadas as linhas centrais, eliminando-se 0,5 m de cada extremidade. A comparação entre as metodologias foi efetuada considerando-se o caráter produção de grãos. Verificou-se correlação de posição significativa dos postos dos genótipos, entre o desvio da regressão e as duas medidas não-paramétricas de estabilidade, porém o mesmo não foi observado entre o coeficiente de regressão e as medidas não-paramétricas (Si(1) e Si(2)). As medidas Si(1) e Si(2) mostraram-se quase que perfeitamente correlacionadas.

Evaluation of Fly Ash in Portland Cement Concrete Paving in Woodbury County, Iowa, HR-201, Construction Report, 1979

The earliest overall comprehensive work on the use of fly ash in concrete was reported by Davis and Associates of the University of California in 1937. Since that time there have been numerous applications of the use and varying proportions of fly ash in portland cement concrete mixes. Fly ash is a pozzolanic powdery by-product of the coal combustion process which is recovered from flue gases and is generally associated with electric power generating plants. Environmental regulations enacted in recent years have required that fly ash be removed from the flue gases to maintain clean air standards. This has resulted in an increased volume of high quality fly ash that is considered a waste product or a by-product that can be utilized in products such as portland cement concrete. There are several sources of the high quality fly ash located in Iowa currently producing a combined total of 281,000 tons of material annually. Due to recent cement shortages and the rapidly increasing highway construction costs, the Iowa Department of Transportation has become interested in utilizing fly ash in portland cement concrete paving mixes. A preliminary review of the Iowa Department of Transportation Materials Laboratory study indicates that a substitution of fly ash for portland cement, within limits, is ·not detrimental to the overall concrete quality. Also the use of fly ash in concrete would reduce the cement consumption as well as provide a potential cost savings in areas where high quality fly ash is available without excessive transportation costs. The previously expressed concerns have shown the need for a research project to develop our knowledge of fly ash replacement in the Iowa Department of Transportation portland cement concrete paving mixes.

Floods of September 15-16, 1992, in the Thompson, Weldon, and Chariton River Basins, South-Central Iowa, HR-140, 1997

Water-surface-elevation profiles and peak discharges for the floods of September 15-16, 1992, in the Thompson, Weldon, and Chariton River Basins, south-central Iowa, are presented in this report. The profiles illustrate the 1992 floods along the Thompson, Weldon, Chariton, and South Fork Chariton Rivers and along Elk Creek in the south-central Iowa counties of Adair, Clarke, Decatur, Lucas, Madison, Ringgold, Union, and Wayne. Water-surface-elevation profiles for the floods of July 4, 1981, along the Chariton River in Lucas County and along the South Fork Chariton River in Wayne County also are included in the report for comparative purposes. The September 15-16, 1992, floods are the largest known peak discharges at gaging stations Thompson River at Davis City (station number 06898000) 57,000 cubic feet per second, Weldon River near Leon (station number 06898400) 76,200 cubic feet per second, Chariton River near Chariton (station number 06903400) 37,700 cubic feet per second, and South Fork Chariton River near Promise City (station number 06903700) 70,600 cubic feet per second. The peak discharges were, respectively, 1.7, 2.6, 1.4, and 2.1 times larger than calculated 100-year recurrence-interval discharges. The report provides information on flood stages and discharges and floodflow frequencies for streamflow-gaging stations in the Thompson, Weldon, and Chariton River Basins using flood information collected through 1995. Information on temporary bench marks and reference points established in the Thompson and Weldon River Basins during 1994-95, and in the Chariton River Basin during 1983-84 and 1994-95, also is included in the report. A flood history summarizes rainfall conditions and damages for floods that occurred during 1947, 1959, 1981, 1992, and 1993.

Adaptabilidade e estabilidade de híbridos de famílias endogâmicas de milho, obtidos pelo método dos híbridos crípticos

Neste trabalho avaliou-se o comportamento de híbridos de famílias endogâmicas de milho obtidos pelo método dos híbridos crípticos, produzidos pelo programa de melhoramento de milho do Departamento de Biologia da UFV. A caracterização dos híbridos foi feita com base em 22 ambientes, usando-se os métodos de Eberhart & Russell e de Carneiro. Pelo método de Eberhart & Russell, foram identificados 15 híbridos com produção acima da média geral. Entre eles, 53,3% tiveram bom desempenho em qualquer ambiente, e alta estabilidade (84-6, 86-1, 86-19, 86-11, 86-15, 86-21, 86-27 e 86-10), e 20% são mais responsivos à melhoria ambiental e possuem alta estabilidade (86-22, 85-2 e 84-5). Os híbridos 85-1, 85-3 e 86-2 apresentaram bom desempenho em qualquer ambiente e baixa estabilidade, correspondem também a 20% dos mais produtivos. O último (86-8), correspondendo a 6,7%, apresentou adaptação específica a ambientes favoráveis, e baixa estabilidade. Pela análise, considerando o método de Carneiro, foram identificados os híbridos 86-22, 86-8, 84-5, 85-2 e 86-19 como os mais responsivos à melhoria do ambiente. Os híbridos 86-11, 85-3, 86-27 e 86-2 apresentaram adaptação a ambientes desfavoráveis.

AltitudeOmics: The Integrative Physiology of Human Acclimatization to Hypobaric Hypoxia and Its Retention upon Reascent.

An understanding of human responses to hypoxia is important for the health of millions of people worldwide who visit, live, or work in the hypoxic environment encountered at high altitudes. In spite of dozens of studies over the last 100 years, the basic mechanisms controlling acclimatization to hypoxia remain largely unknown. The AltitudeOmics project aimed to bridge this gap. Our goals were 1) to describe a phenotype for successful acclimatization and assess its retention and 2) use these findings as a foundation for companion mechanistic studies. Our approach was to characterize acclimatization by measuring changes in arterial oxygenation and hemoglobin concentration [Hb], acute mountain sickness (AMS), cognitive function, and exercise performance in 21 subjects as they acclimatized to 5260 m over 16 days. We then focused on the retention of acclimatization by having subjects reascend to 5260 m after either 7 (n = 14) or 21 (n = 7) days at 1525 m. At 16 days at 5260 m we observed: 1) increases in arterial oxygenation and [Hb] (compared to acute hypoxia: PaO2 rose 9±4 mmHg to 45±4 while PaCO2 dropped a further 6±3 mmHg to 21±3, and [Hb] rose 1.8±0.7 g/dL to 16±2 g/dL; 2) no AMS; 3) improved cognitive function; and 4) improved exercise performance by 8±8% (all changes p<0.01). Upon reascent, we observed retention of arterial oxygenation but not [Hb], protection from AMS, retention of exercise performance, less retention of cognitive function; and noted that some of these effects lasted for 21 days. Taken together, these findings reveal new information about retention of acclimatization, and can be used as a physiological foundation to explore the molecular mechanisms of acclimatization and its retention.

Diallel analysis for frogeye leaf spot resistance in soybean

Seven soybean cultivars (Bossier, Cristalina, Davis, Kent, Lincoln, Paraná and Uberaba), with different levels of resistance to Cercospora sojina, were crossed in a diallel design to determine the general (GCA) and specific (SCA) combining abilities relative to the inheritance of the resistance. Race 04 of the fungus was inoculated in the parents and in the 21 F1 hybrids in a greenhouse in a completely randomized design, with 12 replications. The reactions to the disease were evaluated 20 days after the inoculation, always on the most infected leaflet. Both GCA and SCA were significant for all the evaluated characters, being inferred that, for the expression of the characters, the additive, dominant and, possibly, epistatic genic actions were important. The largest values of estimated SCA effect (ij) were observed in the hybrid combinations where at least one parent presented high GCA. Cristalina, Davis and Uberaba cultivars showed the largest estimates for GCA effect (i), and from the analysis of ii, the contribution of these parents to heterosis of their hybrids will be towards the reduction of the disease symptoms. Therefore, these cultivars are indicated as parents in breeding programs that seek the development of soybean cultivars with resistance to frogeye leaf spot.
