Abstract: According to certain embodiments, a method in a network node (100A) for determining spectrum utilization for a plurality of numerologies transmitted within an allocated bandwidth includes selecting one or more of the plurality of numerologies. For each of the one or more selected numerologies, a spectrum utilization is determined. The spectrum utilization is based on the spectrum utilization that would be achieved if the selected numerology was transmitted across the allocated bandwidth. A physical resource block (PRB) allocation is calculated based on the allocated bandwidth and the spectrum utilization.

Abstract: A rotary valve is used to control fluid flow within a fluid delivery system. The valve may include a valve body having multiple ports that are connected to the system, and a lid that closes an open end of the valve body. A diverter disposed in the valve body is driven to rotate via a shaft. The shaft protrudes from the valve body through a sleeve provided in the lid. The sleeve includes an internal shoulder. A seal retainer engages the sleeve and retains a shaft seal in a desired position between the shaft and the sleeve. The seal retainer includes an endplate having a central opening that receives the shaft, and a collar that protrudes from the endplate inner surface so as to reside between the sleeve and the shaft. An end face of the collar faces the shoulder with the seal disposed between the end face and shoulder.
