In order to meet the needs of on-site calibration of tritium monitor, the on-site calibration technology of tritium monitor is studied.According to the calibration method recommended by international standards, a portable calibration device was established, and the reference tritium gas for calibration was diluted and prepared by mass flow method.I
Utilizing crushed spontaneous combustion coal gangue as a coarse aggregate in concrete preparation effectively reduces reliance on natural resources and mitigates environmental pollution; however, the suboptimal workability of spontaneous combustion coal gangue coarse aggregate concrete (SCG-CAC) limits its engineering applications.To address this
Family history of Coaxial Adaptor tobacco use and use of e-cigarettes have both been associated with increased tobacco use among young adults.However, to our knowledge, these variables have not been considered simultaneously.This study was designed to evaluate the hypothesis that family history of tobacco use would predict tobacco product use over
Pufferfish, globally recognized for its distinctive delicacy, carries high Absorbent Products culinary value.However, it is also notorious for the lethal toxicity, and there is a great demand for traceability measures in the commercial trade of pufferfish to assure safety and accountability.This research introduces a novel deep learning approach, u
Detailed stratigraphic work in the course of four geologic expeditions has allowed refinement of the Early Cretaceous stratigraphy of the Zanskar Range.The Giumal Sandstone, which is comprised between the Late Jurassic to earliest Cretaceous? Spiti Shale and the mid-Cretaceous Chikkim and Fatu La pelagic limestones, is formally elevated to Group ra
