Abstract: Methods and systems are provided for delaying a dynamic connection modification of a user device connection. A first frequency band is determined to have a greater sector power ratio (SPR) than a second frequency band. The first frequency band is determined to have a loading factor above a threshold. Based at least in part on the first frequency band having the greater SPR and the first frequency band having the loading factor above the threshold, a connection of the user device to the first frequency band for access for to a wireless communication protocol is delayed.

Abstract: Method and apparatus pertaining to the production of hydrogen sulfide using sodium salts recycle. Sodium sulfate is reacted with a carbon containing stream to produce sodium sulfide and carbon dioxide. The sodium sulfide is blended with elemental sulfur and water. The blend is subjected to elevated temperatures and pressures to result in the production of hydrogen sulfide and sodium sulfate. A mixing apparatus, such as a bubble column reactor, has been found to be especially useful. The hydrogen sulfide can be used for removing metal from effluents.

Abstract: A communication system includes a first wireless base station supporting communications with multiple mobile communication devices. The first wireless base station is limited to an amount of power it is able to consume. For example, the wireless base station receives power consumption information from a power consumption manager. To control power consumption with respect to the received power consumption information, the wireless base station determines (such as based on an estimation, calculation, measurement, etc.), an amount of a power consumption by the wireless base station while communicating with multiple mobile communication devices. The wireless base station adjusts wireless communications transmitted from the wireless base station to maintain the power consumption of the wireless base station with respect to a power consumption limit as indicated by the received power consumption information.
