Rhizobia synthesize a class of lipo-chitin oligosaccharides that induce root hair deformation and induce the initiation of nodule structures on legume roots. These lipo-chitin oligosaccharides are tetra- and penta-lipo-oligosaccharides of N-acetylglucosamine with an acyl substitution on the nonreducing end and are commonly known as Nod factors.

This paper presents a spherical motor driven by electro-magnets that can rotate omnidirectionally with some degrees of rotation angle error independent of rotation direction. The spherical motor is composed of a spherical rotor, a semi-spherical stator, a control PC, a control circuit, and a DC power supply. The rotor has 92 neodymium magnets. On the other(More)
