The objective of this study was to produce artificial antigens for astragaloside IV that could be used to prepare antibodies against astragaloside IV screened in Radix astragali (Astragalus membranaceus (Fisch) Bunge, Fabaceae) and its preparations, using an indirect ELISA. Astragaloside IV was coupled to carrier proteins, bovine serum albumin and ovalbumin using the sodium periodate method and was...
The moisture diffusion phenomenon and moisture stress in a specific LED module was studied in this paper. Firstly, the finite element model of the LED module was built. The moisture diffusion distribution at operation condition with 25 °C ∼ 85 °C, was analyzed. Secondly, the temperature distribution and moisture distribution of the LED module during reflow soldering process were simulated at the initial...
