Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles.In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating aneuploid or polyploid progeny, respectively.Accurate segregation requires the coordinated execu
Abstract Nitrification is believed to be one of the primary processes of N2O emission in the agroecological system, which is controlled by soil microbes and mainly regulated by soil pH, oxygen content and NH4 + availability.Previous studies have proved that the relative contributions of ammonia oxidizing bacteria (AOB) and archaea (AOA) to N2O prod
This paper describes a comparison of contemporary and historical light water reactor shielding and pressure vessel dosimetry cross-section libraries for a boiling water reactor calculational benchmark problem.The calculational benchmark problem was developed at Brookhaven National Laboratory by the request of the U.S.Nuclear Regulatory Commission.T
At present, the walking and drilling operations of the mine kilometer directional drilling rig are all realized by the manual operation of drillers.The intelligence level is low.At present, there is no research on the correlation between the action type of kilometer directional drilling rig and the vibration state of the hydraulic pump station.Ther
