In order to meet the needs of on-site skull bride and groom 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
Cells of the spinal cord and somites arise from shared, dual-fated precursors, located towards the posterior of the elongating embryo.Here we show that these neuromesodermal progenitors (NMPs) can readily be generated in vitro from mouse and human pluripotent stem cells by activating Wnt and Fgf signalling, timed to emulate in vivo development.Simi
The article is devoted to the study of the historiography of maritime transport and customs clearance.The historical aspects of the development of customs clearance in maritime transport are covered.The origin of shipbuilding and the development of navigation are analyzed, and it is here indicated that in the process the customs for the transportat

Although studies have revealed the significant impact of dietary fiber on growth performance and nutrient digestibility, the specific characteristics of the intestinal microbiota and gene regulation in pigs capable of digesting high-fiber diets remained unclear.To investigate the traits associated with roughage tolerance in the Chinese color touch
