Isolation and characterization of intergeneric somatic hybrids in the Apocynaceae family
Protoplasts were isolated from callus cultures of Rauwolfia serpentina Benth., Rhazya stricta Decaisne, and Catharanthus roseus (L.) G. Don, or from leaves of Vinca minor L. Protoplast isolation, culture, and fusion techniques as well as hybrid screening systems were developed for these species, and hybrids were obtained. Hybrid combinations were Rauwolfia + Vinca, Rauwolfia + Catharanthus, Rauwolfia + Rhazya, and Catharanthus + Vinca. For hybrid isolation, the physiological complementation method was utilized. Analyses of the material obtained included a cytogenetic study of the chromosomes, a study of multiple molecular forms of transferases and esterases, and the blot hybridization of re…
Liquid argon calorimeter performance at high rates
Abstract We project the performance of the ATLAS liquid argon endcap and forward calorimeters at the planned high luminosity LHC option HL-LHC by exposing small calorimeter modules of the electromagnetic, hadronic, and forward calorimeters to high intensity beams at IHEP/Protvino. The beam intensity extends well beyond the maximum expected for these calorimeters at HL-LHC. The signal reconstruction and calorimeter performance have been studied in full detail.
