Summary: This study successfully detected Pseudomonas syringae pv. aesculi on symptomatic horse chestnut trees in Switzerland, and found that reduced isolation success and low copy numbers of the target gene were correlated with the increasing age of symptomatic trees. The experiment showed that detectability of DNA from the bacteria dropped by 34.5% one day after inoculation and remained relatively stable until the end of the experiment, while no bacterial growth was observed after inactivation.

Summary: The rapidly solidified hypereutectic Al-3Ni-3Sb alloy exhibited significantly reduced particle size of Al3Ni intermetallic compounds, leading to a more than doubled microhardness compared to conventional cast alloys. This enhancement in microhardness was attributed to the contraction of Al3Ni intermetallic structure on the alloy surface.
