A new cultivar of Buxus semperivirens, \u2018Sky Walker\u2019, characterized by its very rapid growth rate that continues at least for six growing period, its very columnar plant habit with a low amount of lateral branching, its foliage with good color retention throughout the growing season, its greater degree of resistance to root diseases than is typical of Buxus. For example, the method and system may be used to archive documents. The converter is suitable for converting a parallel bus structure to a serial bus structure, and the converter is also suitable for supporting a parallel bus structure to a parallel bus structure. The lighting system promotes a component change of the plant effectively by a stimulation by the UV-B irradiation and the prolonged irradiation time of the visible light which is associated with a vegetative growth, so that a nutritional component of the plant can stably be increased. Embodiments of the incised cannula exhibit reduced tissue trauma compared with screw-threaded cannula, improved fixation andor retention compared with an unthreaded cannula, and good sealing between the cannula and the incision. A subscriber station in the network may monitor the dedicated subcarriers to determine when a burst involving the station is to occur.
