Abstract: Oleophobic and/or philic surface(s) are utilized for oil separation, direction, and/or collection in a refrigeration system. Surfaces of component(s) of a refrigeration system (compressor, oil separator, evaporator, etc.) are produced to be oleophobic or philic. The oleophobic and/or philic surfaces are utilized to direct a flow path of oil within the refrigeration system or to prevent oil connection in an area. Refrigerant phobic and/or lubricant phobic material(s) also may be utilized to help promote separation of refrigerant vapor from refrigerant liquid and/or from oil in refrigeration systems.

Abstract: In non-limiting examples of the present disclosure, systems, methods and devices for surfacing collaborative recommendations in relation to topically classified resources are presented. Resources may be topically classified based on application of natural language processing and machine learning models. Relationships amongst users that own, authored and/or edited the resources may be identified. Recommendations may be surfaced based on topical and/or user characteristic overlap associated with the resources. The recommendations may relate to group collaboration on resource creation, sharing of related resources, incorporating related resources in existing resources, and/or recommending group creation and/or collaboration associated with resource topics.

Abstract: A system and methodology facilitates the handling of oilfield materials in a space efficient manner. The oilfield materials are delivered without blowers to at least one modular silo. Each modular silo comprises an outer housing defining an enclosed interior. A vertical conveyor is positioned within the enclosed interior and is used to lift the oilfield material from a silo inlet to an upper portion of the modular silo without utilizing airflow to carry the oilfield materials. Once the oilfield materials are disposed within the upright modular silo, the outflow of oilfield materials through a silo outlet may be controlled so as to selectively release the desired amount of material into a blender or other suitable equipment.

Abstract: In non-limiting examples of the present disclosure, systems, methods and devices for assisting with event execution are provided. Data from a productivity application associated with a user may be analyzed. A significant life event associated with the user may be identified based on the analysis. A plurality of sources that each have at least one recommendation for executing a type of event corresponding to the significant event may be identified. An itinerary template for the significant life event may be generated from a plurality of the recommendations. The itinerary template may be surfaced. Additional examples of the present disclosure relate to identifying relevant applications for download to a user's device managed by an administrator device.

Abstract: Methods, systems, and apparatus for correlating communications measurements are disclosed. In one aspect, a communications measurement of a maintenance entity (ME) is received. The communications measurement is stored and correlated with a maintenance entity group (MEG) identifier and an ME identifier received with the communications measurement. The stored communications measurement is registered with one or more previously received communications measurements. Each previously received communications measurement is associated with an availability indicator corresponding to an availability of the ME at a time the particular communications measurement was obtained. An availability of the ME during a given time interval is determined based on availability indicators of consecutive communications measurements for the ME.
