We have developed a semianalytic expression for the total energy loss to a vacuum transmission-line electrode operated at high lineal current densities. (We define the lineal current density j_{ℓ}≡B/μ_{0} to be the current per unit electrode wid

Publikováno v: Physical Review Special Topics. Accelerators and Beams, Vol 11, Iss 10, p 100401 (2008)
We have developed a system of differential-output monitors that diagnose current and voltage in the vacuum section of a 20-MA 3-MV pulsed-power accelerator. The system includes 62 gauges: 3 current and 6 voltage monitors that are fielded on each of t

Agronomic and Economic Evaluations of N Fertilization in Maize under Recent Market Dynamics
Autor: Yesuf Assen Mohammed, Russ W. Gesch, Jane M. F. Johnson, Steve W. Wagner
Publikováno v: Nitrogen, Vol 3, Iss 3, Pp 514-527 (2022)
An online calculator is available to determine economic optimum nitrogen rate (EONR) for maize (Zea mays L.) production in the USA Corn Belt. For Minnesota, this calculator considers nitrogen (N) fertilizer cost, maize grain price and crop history, a

Publikováno v: Agrosystems, Geosciences & Environment, Vol 4, Iss 4, Pp n/a-n/a (2021)
Abstract The Conservation Reserve Program (CRP) has been a major factor in land transitions out of intensive row‐crop management on marginally productive lands in the central United States. While CRP can protect these more environmentally sensitive
