Proteomics to identify biological pathways and develop prediction models of coronary microvascular dysfunction in women with angina and no obstructive coronary artery disease
Autor: E Prescott, K Bove, H E Suhrs, D F Bechsgaard, T Lange, J Schroder, R L Nielsen
Publikováno v: European Heart Journal. 43
Aims Coronary microvascular dysfunction (CMD) is a major cause of angina and impaired outcome. Protein biomarkers could simplify patient selection for assessment and help uncover pathophysiologic pathways. Methods and results We quantified 184 protei

Influence of Nitrogen Application Timing on Low Density Giant Ragweed (Ambrosia Trifida) Interference in Corn
Autor: William G. Johnson, Kevin D. Gibson, Thomas T. Bauman, E.J. Ott, R. L. Nielsen
Publikováno v: Weed Technology. 21:763-767
Field experiments were conducted to evaluate the influence of three nitrogen fertilizer application timings on corn and giant ragweed dry weight, corn and giant ragweed nitrogen accumulation, and corn grain yield. By the V8 growth stage, corn plants

Delayed Planting Effects on Flowering and Grain Maturation of Dent Corn
Autor: Peter R. Thomison, Jason Wells, R. L. Nielsen, Anthony L. Halter, Kirby L. Wuethrich, Gregory A. Brown
Publikováno v: Agronomy Journal. 94:549-558
Delayed planting shortens the effective growing season for corn (Zea mays L.), increasing the risk of exposure to lethal cold temperatures late in the season before grain maturation. Consequently, growers often must decide whether to switch to early

Accurate prediction of phenological development in maize (Zea mays L.) is fundamental to determining crop adaptation and yield potential. A number of thermal functions are used in crop models, but their relative precision in predicting maize developm

On the nature of eutectic carbides in Cr-Ni white cast irons
Autor: N. H. Macmillan, R. L. Nielsen, George Laird
Publikováno v: Metallurgical Transactions A. 22:1709-1719
The mechanical and tribological properties of white cast irons are strongly dependent on whether they contain M7C3 or M3C carbides (M = Fe, Cr,etc.). In an effort to improve the wear resistance of such materials, the United States Bureau of Mines has

Planting Speed Effects on Stand Establishment and Grain Yield of Corn
Autor: R. L. Nielsen
Publikováno v: Journal of Production Agriculture. 8:391-393
Planting speed can affect a planter's ability to uniformly singulate and deliver seed to the seed furrow. A replicated on-farm strip trial was conducted in 1993 on 22 farms in three states to evaluate the effect of planting speed (4, 5, 6, and 7 mph)

Planting Field‐Scale Research Plots with the Aid of GPS‐Enabled Assisted Steering
Autor: Norman Larson, Jacky Payne, Eric White, R. L. Nielsen
Publikováno v: Agronomy Journal. 100:777-778
Field-scale research imposes logistical challenges to planting randomized treatment plots, even for simply designed field experiments. Planter row markers offer minimal assistance when planting randomly located strips of a treatment across a field. A
