Development of a metal-free amine oxidation method utilizing DEAD chemistry
Autor: G. Piva de Silva, N. E. Wiebe, G. M. Fehr, G. Wang, R. L. Davis
Publikováno v: RSC Adv.. 7:48848-48852
Herein, we examine the oxidative abilities of azodicarboxylates for the conversion of amines to imines. This method provides access to synthetically useful imine intermediates including β-carbolines, quinazolines and N-heterocyclic carbene precursor

Phosphorus Loss in Runoff from Long-term Continuous Wheat Fertility Trials
Autor: Wade Everett Thomason, Mark E. Payton, Jim J. Wang, R. L. Davis, William R. Raun, Hailin Zhang, Jackie L. Schroder, Y. Tang
Publikováno v: Soil Science Society of America Journal. 70:163-171
Some wheat (Triticum aestivum L.) farmers in the southern Great Plains routinely apply P fertilizer without soil testing. This practice may lead to P buildup in soils, hence, increased P runoff potential, making soil P management of concern in contin

Water‐Soluble Phosphorus as Affected by Soil to Extractant Ratios, Extraction Times, and Electrolyte
Autor: J. K. Fuhrman, Mark E. Payton, Jackie L. Schroder, Hailin Zhang, R. L. Davis
Publikováno v: Communications in Soil Science and Plant Analysis. 36:925-935
One of the most important nutrients for plant production is phosphorus (P). However mismanagement of fertilizer or manure can lead to P build‐up in surface soils and elevate P loss in runoff possibly resulting in accelerated eutrophication. Concern

Publikováno v: Journal of Plant Nutrition. 26:1561-1580
The Magruder plots are the oldest continuous soil fertility wheat research plots in the Great Plains region, and are one of the oldest continuous soil fertility wheat plots in the world. They were initiated in 1892 by Alexander C. Magruder who was in

Influence of Vane-Blade Spacing on Transonic Turbine Stage Aerodynamics: Part I—Time-Averaged Data and Analysis
Autor: B. L. Venable, R. A. Delaney, J. A. Busby, R. L. Davis, D. J. Dorney, M. G. Dunn, C. W. Haldeman, R. S. Abhari
Publikováno v: Journal of Turbomachinery. 121:663-672
A comprehensive study has been performed to determine the influence of vane-blade spacing on transonic turbine stage aerodynamics. In Part I of this paper, an investigation of the effect of turbine vane–blade interaction on the time-mean airfoil su
