Mixtures of select neopentyl polyol esters are found to be highly miscible with the refrigerant R-32 over a wide temperature range. The display unit displays a first display object indicating a focal point adjustment area on a display image of the object image in response to detection of the first close condition, and displays a second display object indicating a focusing command area on the display image of the object image corresponding to a range of detection of the second close condition. The partial pre-aggregation creates a record store in memory as input records are received. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for hybrid bearings, turbine engine systems with one or more hybrid bearings and turbine engine powered systems with one or more hybrid bearings. The crane folds to a compact configuration behind the cab of the tracked vehicle and, when extended, can access poles up to 85 feet tall.
