Ultrathin Portland Cement Concrete Overlay Extended Evaluation, Construction Report, TR-432, 2000

In recent years, ultra-thin whitetopping (UTW) has evolved as a viable rehabilitation technique for deteriorated asphalt cement concrete (ACC) pavement. Numerous UTW projects have been constructed and tested, enabling researchers to identify key elements contributing to their successful performance. These elements include foundation support, interface bonding condition, portland cement concrete (PCC) overlay thickness, synthetic fiber reinforcement usage, joint spacing, and joint sealing. The interface bonding condition is the most important of these elements. It enables the pavement to act as a composite structure, thus reducing tensile stresses and allowing an ultra-thin PCC overlay to perform as intended. The Iowa Department of Transportation (Iowa DOT) UTW project (HR-559) initiated UTW in Iowa. The project is located on Iowa Highway 21 between Iowa Highway 212 and U.S. Highway 6 in Iowa County, near Belle Plaine, Iowa. The objective of this research was to investigate the interface bonding condition between an ultra-thin PCC overlay and an ACC base over time, considering the previously mentioned variables. This research lasted for five years, at which time it was extended an additional five years. The new phase of the project was initiated by removing cracked panels existing in the 2-inch thick PCC sections and replacing them with three inches of PCC. The project extension (TR 432) will provide an increased understanding of slab bonding conditions over a longer period, as well as knowledge regarding the behavior of the newly rehabilitated areas. In order to accomplish the goals of the project extension, Falling Weight Deflectometer (FWD) testing will continue to be conducted. Laboratory testing, field strain gage implementation, and coring will no longer be conducted. This report documents the planning and construction of the rehabilitation of HR 559 and the beginning of TR 432 during August of 1999.

the Gypsy Moth, September 2000

The Gypsy moth is a serious pest of trees ans shrubs. It damages the plants when the caterpillar stage eats the leaves. When there are many caterpillars, They defoliate entire trees, which can weaken and sometimes kill the trees. The gypsy moth is a notorious hitchhiker; it has been brought into Iowa on recreations vehicles and nursery stock. Learning the recognize the gypsy moth is an important part of preventing infestations and severe damage to Iowa's forests, woodlands, and urban landscapes.

Natural resources : final report to the Governor's Conference on Iowa in the Year 2000, 1974

Includes discussion and findings by a key note speaker at Natural Resources Task Force Workshop on trends to do with Iowa's natural resources such as urban and rural development on agricultural land, cultivation, farm ownership, air quality, disposing of solid waste and the recreational needs and the possibility of creating new agencies to deal with natural resources planning and regulation.

The frequency and prognostic impact of dic(9;20)(p13.2;q11.2) in childhood B-cell precursor acute lymphoblastic leukemia: results from the NOPHO ALL-2000 trial.

The dic(9;20)(p13.2;q11.2) is reported to be present in ∼2% of childhood B-cell precursor acute lymphoblastic leukemia (BCP ALL). However, it easily escapes detection by G-banding analysis and its true prevalence is hence unknown. We performed interphase fluorescence in situ hybridization analyses-in a three-step manner-using probes for: (i) CDKN2A at 9p21, (ii) 20p and 20q subtelomeres and (iii) cen9 and cen20. Out of 1033 BCP ALLs diagnosed from 2001 to 2006, 533 were analyzed; 16% (84/533) displayed 9p21 deletions, of which 30% (25/84) had dic(9;20). Thus, dic(9;20)-positivity was found in 4.7% (25/533), making it the third most common genetic subgroup after high hyperdiploidy and t(12;21)(p13;q22). The dic(9;20) was associated with a female predominance and an age peak at 3 years; 18/25 (72%) were allocated to non-standard risk treatment at diagnosis. Including cases detected by G-banding alone, 29 dic(9;20)-positive cases were treated according to the NOPHO ALL 2000 protocol. Relapses occurred in 24% (7/29) resulting in a 5-year event-free survival of 0.69, which was significantly worse than for t(12;21) (0.87; P=0.002) and high hyperdiploidy (0.82; P=0.04). We conclude that dic(9;20) is twice as common as previously surmised, with many cases going undetected by G-banding analysis, and that dic(9;20) should be considered a non-standard risk abnormality.

2000 Iowa Termination of Pregnancy Report, May 1, 2002

This report is a compilation of data on reported terminations of pregnancy in Iowa. These are terminations that actually occurred during the period from January 2000 through December 2000. The annual reporting of termination of pregnancy events is required by state legislation. With this legislative requirement, Iowa joins the other 49 states, the District of Columbia, and New York City in providing information that relates to issues of pregnancy, termination of pregnancy, live births, and fetal deaths (1). This information contributes to the ability of public health officials and policy makers to better understand these issues. The Iowa reporting system is a variation on the model published by the National Center for Health Statistics in 1987 (2). These guidelines described the criteria and expectations for reporting pregnancy information.

Adaptabilidade e estabilidade de cultivares de milho no Nordeste brasileiro no triênio 1998 a 2000

Foram avaliadas 22 cultivares de milho (variedades, híbridos e populações) em 45 ambientes do Nordeste brasileiro, no triênio 1998 a 2000, objetivando conhecer a adaptabilidade e a estabilidade desses materiais para fins de recomendação. Utilizou-se delineamento experimental em blocos ao acaso com três repetições. A análise de variância conjunta mostrou inconsistência no comportamento das cultivares diante das variações ambientais. Os híbridos mostraram melhor adaptação que as variedades e populações, constituindo-se em alternativas viáveis para os produtores que investem em tecnologias modernas de produção; sobressaíram-se Cargill 333 B, AG 1051 e Zeneca 8501. As variedades Sertanejo, AL 25, São Francisco, São Vicente, Asa Branca e BR 106 são importantes nos sistemas de produção dos pequenos e médios produtores rurais da região.
