Effects of Heat Straightening Structural Steel, MLR-91-3, 1992

Heat straightening of steel beams on bridges struck by over height trucks has become common practice in recent years in Iowa. A study of the effects of this heat straightening on the steel beams thus straightened is needed. Appropriate samples for mechanical and metallurgical tests were cut from the same rolled beam from the end which was heated and the end which was not heated and the test results were compared. The test results showed beyond doubt that the steel was being heated beyond the permitted temperature and that the impact properties are being drastically reduced by the current method of heat straightening.

Correlation of the IJK Roadmeter to the International Roughness Index, MLR-91-5, 1992

The Iowa Department of Transportation has been determining a present serviceability index (PSI) on the primary highway system since 1968. A CHLOE profilometer has been used as the standard for calibrating the Roadmeters that do the system survey. The current Roadmeter, an IJK Iowa DOT developed unit, is not considered an acceptable Roadmeter for determining the FHWA required International Roughness Index (IRI). Iowa purchased a commercial version of the South Dakota type profile (SD Unit) to obtain IRI. This study was undertaken to correlate the IRI to the IJK Roadmeter and retire the Roadmeter. One hundred forty-seven pavement management sections (IPMS) were tested in June and July 1991 with both units. Correlation coefficients and standard error of estimates were: r' Std. Error PCC pavements 0.81 0.15 Composite pavements 0.71 0.18 ACC pavements 0.77 0.17 The correlation equations developed from this work will allow use of the IRI to predict the IJK Roadmeter response with sufficient accuracy. Trend analysis should also not be affected.

Induction of CD8 T-cell responses restricted to multiple HLA class I alleles in a cancer patient by immunization with a 20-mer NY-ESO-1f (NY-ESO-1 91-110) peptide.

Immunogenicity of a long 20-mer NY-ESO-1f peptide vaccine was evaluated in a lung cancer patient TK-f01, immunized with the peptide with Picibanil OK-432 and Montanide ISA-51. We showed that internalization of the peptide was necessary to present CD8 T-cell epitopes on APC, contrasting with the direct presentation of the short epitope. CD8 T-cell responses restricted to all five HLA class I alleles were induced in the patient after the peptide vaccination. Clonal analysis showed that B*35:01 and B*52:01-restricted CD8 T-cell responses were the two dominant responses. The minimal epitopes recognized by A*24:02, B*35:01, B*52:01 and C*12:02-restricted CD8 T-cell clones were defined and peptide/HLA tetramers were produced. NY-ESO-1 91-101 on A*24:02, NY-ESO-1 92-102 on B*35:01, NY-ESO-1 96-104 on B*52:01 and NY-ESO-1 96-104 on C*12:02 were new epitopes first defined in this study. Identification of the A*24:02 epitope is highly relevant for studying the Japanese population because of its high expression frequency (60%). High affinity CD8 T-cells recognizing tumor cells naturally expressing the epitopes and matched HLA were induced at a significant level. The findings suggest the usefulness of a long 20-mer NY-ESO-1f peptide harboring multiple CD8 T-cell epitopes as an NY-ESO-1 vaccine. Characterization of CD8 T-cell responses in immunomonitoring using peptide/HLA tetramers revealed that multiple CD8 T-cell responses comprised the dominant response.

Evaluation of Deterioration on US 20 in Webster County, MLR-91-1, 1991

Ten miles of U.S. Highway 20 in Webster County began to show deterioration in 1990. Any deterioration was unexpected, since the road was just constructed in 1986 and 1987. The deterioration looked much like the staining and cracking of D-cracking. Cracking was found on 391 joints throughout the 10 mile four lane divided highway. Evaluation of cores from the project reveal low air contents at those locations where cracking is occurring. The cause of the low air contents can only be speculated on. A possible cause may be the vibration from the paver coupled with the additional vibration at the joints. Other projects constructed in 1986 and 1987 with the same equipment show no signs of distress.

Correlation of the Road Rater and the Dynatest Falling Weight Deflectometer, MLR-91-04, 1991

The Falling Weight Deflectometer (FWD) has become the "standard" for deflection testing of pavements. Iowa has used a Road Rater since 1976 to obtain deflection information. A correlation between the Road Rater and the FWD was needed if Iowa was going to continue with the Road Rater. Comparative deflection testing was done using a Road Rater Model 400 and a Pynatest 8000 FWD on 26 pavement sections. The SHRP contractor, Braun Intertec Pavement, Inc., provided the FWD testing. The r^2 for the linear correlations ranged from 0.90 to 0.99 for the different pavement types and sensor locations.

Iowa 58 Viking Road Corridor from U.S. 20 to Greenhill Road in Cedar Falls, Iowa, NHSX-U-58-1(91)--8S-07, 2015

The Proposed Action consists of the improvement of Iowa Highway 58 (IA 58) from U.S. Highway 20 (U.S. 20) north to Greenhill Road in Cedar Falls (Black Hawk County, Iowa). The improvement would include limiting at-grade access to IA 58 by adding one or more interchanges to the corridor which would be located at Viking Road, Greenhill Road, and reconfiguring the U.S. 20 interchange (Figure 1). In order to construct these interchanges and associated ramps, the pavement of IA 58 would be reconstructed. In a couple of locations, the alignment of IA 58 would be shifted.

Reação de clones de umezeiro (Prunus mume Sieb. et Zucc.) e cultivares de pessegueiro [Prunus persica (L.) Batsch] ao nematóide anelado Mesocriconema xenoplax (Nemata: Criconematidae)

Com o objetivo de avaliar a reação de clones de umezeiro (Prunus mume Sieb. et Zucc.) e cultivares de pessegueiro [Prunus persica (L.) Batsch] ao nematóide anelado Mesocriconema xenoplax (Raski) Loof & de Grise, realizou-se o presente estudo em casa de vegetação do Departamento de Fitossanidade da FCAV/UNESP, Câmpus de Jaboticabal-SP. As plantas foram mantidas em vasos de cerâmica com 6 litros de capacidade, contendo uma mistura de solo e areia (1:1, v/v), previamente autoclavada a 121°C e 1kgf.cm-2 por 2 horas. Cada planta foi inoculada com 10mL de uma suspensão de 200 M. xenoplax por mL. Com os resultados obtidos, após 105 dias da inoculação, pode-se concluir que os Clones 05; 10 e 15 de umezeiro e as cultivares Okinawa e Aurora-1 de pessegueiro são suscetíveis a M. xenoplax. A cultivar Aurora-1 apresentou maior Fator de Reprodução (93,06).

Pegamento e crescimento inicial de enxertos do pessegueiro 'Aurora-1' em clones de umezeiro (Prunus mume Sieb. et Zucc.) e 'Okinawa' [Prunus persica (L.) Batsch] propagados por estacas herbáceas

O presente estudo teve por objetivo avaliar o pegamento e o crescimento inicial de enxertos do pessegueiro 'Aurora-1' em clones de umezeiro (Prunus mume Sieb. et Zucc.) e 'Okinawa' [Prunus persica (L.) Batsch] propagados por estacas herbáceas. Realizaram-se dois experimentos, adotando-se a enxertia de borbulhia por escudo (março) e borbulhia por escudo modificada (julho). Com os resultados obtidos, pode-se concluir que é viável a realização da enxertia do 'Aurora-1' nos Clones 05; 10 e 15 de umezeiro e no 'Okinawa', tanto em março quanto em julho, com as metodologias utilizadas. O 'Okinawa' induz crescimento mais rápido ao enxerto, de forma que o ponto máximo do comprimento é atingido em tempo menor.
