ABSTRACT The candidate phyla radiation (CPR) comprises a large monophyletic group of bacterial lineages known almost exclusively based on genomes obtained using cultivation-independent methods.Within the CPR, Gracilibacteria (BD1-5) are particularly poorly understood due to undersampling and the inherent fragmented nature of available genomes.Here,
High-speed railway catenaries are vital components in railway traction power supply systems.To ensure stable contact between the pantograph and the catenary, droppers are positioned between the messenger wire p32 can opener and contact line.The failure of one or more droppers will affect the power supply of the catenary and the operation of the rai

Salinity stress is one of the factors that threatens the growth and yield of corn.The effects of silicon or nanosilicon on salinity alleviation have been reported in some plants.The effects of foliar application of silicon (inorganic and nanopatricle) on mitigation of the effects of salinity stress on some photosynthetic and biochemical parameters
