This invention relates to the control of weeds using a urea herbicide and a 4-benzoylisoxazole or a 2-cyano-1,3-dione herbicide. The cutting angle \u03b8 of the \u03b8-rotated Y-cut X-propagation LiNbO3 substrate is in the range between about 50\xb0 and about 55\xb0. Users can control and organize how recorded content is stored between the drives such that an external drive may be removed from a first gateway device and attached to a second gateway device without losing the ability to access the recorded content from the first gateway device at a later time. Because cooling air is discharged from a discharge window along the stay, heated air will not return to any of air intake window. The switch module logically pairs STS-1s into workingprotect pairs and utilizes the STS-1 granular status information to decide which of the pair is a better copy which is output as the working copy after the cross-connect switch fabric is configured according to user demands. The client application then acknowledges to the database application that the notification has been received.
