Abstract: Systems and methods for extracting data from digital messages for digital group compositions may include (1) identifying content that has been posted to a platform, (2) creating a social-engagement score for the content based on a measure of an amount of social engagement generated in response to the content, (3) determining that the social-engagement score surpasses a threshold, and (4) in response to determining that the social-engagement score surpasses the threshold, displaying the content within the platform as platform-recommended content. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A holding arrangement can be used to hold an ice fishing rod during ice fishing on a frozen body of water. The holding arrangement, among other things, is designed to prevent an ice fishing rod from being pulled through an ice fishing hole and into the water by a fish.

Abstract: Systems, methods, and non-transitory computer-readable media can receive an advertisement rule. An eligible advertiser is determined based on the advertisement rule. An advertisement recommendation is determined for the eligible advertiser based on the advertisement rule. The eligible advertiser is monitored for conversion status information.

Abstract: Hydrogen sulfide is effectively removed from potable water by the combined action of first chlorinating the water and then passing the chlorinated water through a bed of activated carbon. Chlorine is added in large doses to potable water containing dissolved hydrogen sulfide to convert substantially 90% of the hydrogen sulfide to sulfates. The chlorinated water containing residual hydrogen sulfide is then passed through a bed of activated carbon. Chemisorbed nascent oxygen in conjunction with the activated carbon catalytically affect breakdown of the remaining sulfide compounds into elemental sulfur.

Abstract: A solid fuel fired gas turbine system for generating electric power which includes a generator, a turbine for operating the generator, a combustion chamber for burning solid fuel to form heated gas under pressure for operating the turbine, and a continuously regenerating granular filter for removing particulate matter from the pressurized, heated gas. The granular filter is operable at high temperature and pressure and is particularly well suited for continuously cleaning the pressurized, hot gas used to operate the gas turbine without significant loss of gas pressure or temperature.
