Database of nitrification and nitrifiers in the global ocean

Publikováno v: Earth System Science Data, Vol 15, Pp 5039-5077 (2023)

As a key biogeochemical pathway in the marine nitrogen cycle, nitrification (ammonia oxidation and nitrite oxidation) converts the most reduced form of nitrogen – ammonium–ammonia (NH4+–NH3) – into the oxidized species nitrite (NO2-) and nitr

Effects of Proton Radiation Dose, Dose Rate and Dose Fractionation on Hematopoietic Cells in Mice

Autor: X. S. Wan, Ann R. Kennedy, Carly M. Sayers, Jeffrey H. Ware, Manunya Nuth, Adam Rusek, Gabriel Krigsfeld, Jenine K. Sanzari, Stephen Avery

Publikováno v: Radiation Research. 174:325-330

The present study evaluated the acute effects of radiation dose, dose rate and fractionation as well as the energy of protons in hematopoietic cells of irradiated mice. The mice were irradiated with a single dose of 51.24 MeV protons at a dose of 2 G

Effects of nitrogen pressure and pulse bias voltage on the properties of Cr–N coatings deposited by arc ion plating

Autor: X. S. Wan, Chao Sun, Yeran Yang, Sumei Zhao, Jun Gong

Publikováno v: Surface and Coatings Technology. 204:1800-1810

Cr-N coatings were deposited on 1Cr18Ni9Ti stainless steel in the pure N(2) atmosphere by arc ion plating (AIP). The relationships between deposition parameters and coating properties were investigated. X-ray diffraction showed a phase transformation

An exploration of the Kozai resonance in the Kuiper Belt

Autor: X.-S. Wan, Tian-Yi Huang

Publikováno v: Monthly Notices of the Royal Astronomical Society. 377:133-141

The Kozai resonance of Kuiper Belt objects is explored using a model of a circular-restricted three-body problem. We use an analytical approach to find the topological structure of the plane of the eccentricity and the argument of perihelion. We find

[Untitled]

Autor: X.-S. Wan, Z.-F. Dai, Tian-Yi Huang

Publikováno v: Celestial Mechanics and Dynamical Astronomy. 87:121-127

Three resonances, the 3:2 exterior mean motion resonance with Neptune, Kozai resonance and 1:1 super resonance, are known to govern concurrently the stability of the motion of Pluto. We explore numerically the resonance zones in which the three reson

The orbit evolution of 32 plutinos over 100 million year

Autor: X.-S. Wan, T.-Y. Huang

Publikováno v: Astronomy & Astrophysics. 368:700-705

The orbits of thirty two plutinos that are presently in the 3:2 mean motion resonance with Neptune have been integrated numerically and accurately to 10 8 years into the future. Fourteen of them are found in unstable orbits after encountering Neptune
