Conjunction gears, which are also known as helical gears with clutch gears, are used mainly in the transmission and shift design of automobile gearboxes.In this paper, focusing on the hot forging process and microstructure changes after forging, hot tv bracket forging is proposed for manufacturing a conjunction gear according to the characteristics

The structure of floral nectary surface of Sorbus intermedia in different phases of SHORT flower development was examined using scanning electron microscopy.Nectaries in S.intermedia flowers represent a receptacle type.The sculpture of cuticule on nectary epidermis and overlaying cells was described.The differences in the size of striaes on the out

The assembly of neuronal circuits involves the migrations of neurons from their place of birth to their final location in the nervous system, as well as the coordinated growth and patterning of axons and dendrites.In screens for genes required for patterning of the nervous system, we identified the catp-8/P5A-ATPase as an important regulator of neu

Adult muscle stem cells, satellite cells (SCs), endow skeletal muscle with tremendous regenerative capacity.Upon injury, SCs activate, proliferate, and migrate as myoblasts to the injury site where they become myocytes that fuse to form new muscle.How migration is regulated, though, remains largely unknown.Additionally, how migration and fusion, wh
