Application of the first collision source method to CSNS target station shielding calculation

“…The numerical results of Monte Carlo code MCNP [7] and TORT3.2 [8] with FNSUNCL3 [9] for the 3D radiation transport benchmarks have been presented by Chikara Konno [10]. In Fig.…”

Transport equations in moving material Part I: Neutrons and photons

“…The absorption capture probability can be cast, 04 '31) cr 0 = noTr~ 2 kT i721 de (76) -A mq "~ • j (77) with no the number of target nuclei per unit volume, and/3 the reduced de Broglie wavelength, (78) with h the Planck constant. For heavy target nuclei, obviously the center of mass and laboratory frames are roughly the same.…”

Soil Testing and Plant Analysis: Guides to the Fertilization of Horticultural Crops

“…The soluble salt level in the soil can be determined with several water extraction procedures (Bower and Wilcox 1965;Rhoades 1982). In the most common procedure, a 1:2 volume ratio of soil to water is used for extraction of soluble salts, and then the specific conductance of the extract is measured.…”
