      Methods: Fourteen coal-related model compounds (CRMCs) were analyzed using GC/Q-TOF MS with different collision-induced dissociation (CID) energies (5-20 eV). The fragmentation pathways can offer a better understanding of chemical bond breaking, hydrogen transfer, rearrangement reactions and elimination of neutral fragments for CRMCs during the CID process.

      2006-7-3 · 2.2.. Time-of-flight secondary ion mass spectrometry (ToF–SIMS)A sample identified by Hughes (2004) as Kaiata Formation sample A (KFA) was obtained from diamond drillcore (DH1565) located within the perimeter of the proposed north pit of the Cypress mine within the Stockton mine area. The sample contains 2.11 wt.% S. The mineralogy of sample KFA is predominantly quartz, kaolinite, …

      Coal remains a primary fuel for power generation. Herein we present time-of-flight secondary ion mass spectra (ToF-SIMS data) taken with a Ga primary ion beam from ca. 30 coal specimens. These commercially different coal specimens were obtained from coal mining companies and/or power plants. They represent all major coal types used in power generation (bituminous coals, subbituminous coals ...

      Then the measuring distance of 200 m adopts the TOF two-way ranging principle, and the ranging error caused by clock drift is 3.6 mm. It can be seen that the ranging error caused by clock drift is at the level of mm. Compared with TWR ranging, SDS-TWR technology has little effect on the sports field ranging result, and the impact of this error can be reduced during the calibration of the receiver delay …

      2021-10-6 · In order to reveal the impact of a high concentration of CO2 on the soil in the coal mining subsidence area, the surface above the goaf before CO2 injection is regarded as a subsidence area model. Based on the actual vertical depth of 70∼80 m shallow buried coal seam geological conditions, CO2 diffusion in the goaf is regarded as a short-term high-concentration CO2 leakage model.

      To solve the problem of heavy workload and high cost when acquiring the position of Ultra-Wideband (UWB) mobile base stations in sports fields, a fast self-positioning algorithm for UWB mobile base stations algorithm based on Time of Flight (TOF) is proposed. First, according to the layout of the base stations in the sports field, the local coordinate system is determined, and an equation ...

       · Or, if I had excess money with no other plan for it, certainly a valid option. Wood: It costs 10 wood to get a coal in a kiln, plus the setup costs of them, and the interactions to load and unload. If you have an excess of wood with no other plan for it, like literally wood to burn, this is an option.
