According to the invention, there is provided seed and plants of the hybrid corn variety designated CH331298. The surveillance systems are adapted to monitor various kinds of irregular events occurring in the building and the surroundings thereof and output corresponding event messages through the network system. The meta data is generated by automatically detecting marked text strings in the application source code that describe the fault notification points, and extracting from each marked text string support information that corresponds to the fault notification points. A metal seal ring is fixed to the cap member around the cavity. The network terminal is coupled to the network communication device for issuing the specific request to request the network address information of the network communication device and then utilizing the network address information of the network communication device to communicate with the network communication device for accessing the network. The radiation shielding container and the vial comprise one or more vents for movement of a sterilant therethrough for sterilization of the one or more radioactive seeds within the vial.
