Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for generating and maintaining group messaging threads associated with ephemeral content. For instance, the disclosed systems can facilitate the creation of ephemeral content including a customizable group messaging graphical element associated with the ephemeral content the enables users to join a group messaging thread associated with the ephemeral content. In addition, the disclosed systems can generate user requests to join the group messaging thread based on user interaction with a group messaging graphical element within ephemeral content and can present the requests to the creator of the ephemeral content. Accordingly, in various embodiments, the disclosed systems can facilitate group messaging threads between creators of ephemeral content and users that view the ephemeral content via associated group messaging graphical elements.

Abstract: A layer protecting the surface of zirconium alloys used as materials for nuclear reactors is formed by a homogenous polycrystalline diamond layer prepared by chemical vapor deposition method. This diamond layer is 100 nm to 50 ?m thick and the size of the crystalline cores in the layer ranges from 10 nm to 500 nm. Maximum content of non-diamond carbon is 25 mol %, total content of non-carbon impurities is maximum up to 0.5 mol %, RMS surface roughness of the polycrystalline diamond layer has a value less than 40 nm and thermal conductivity of the layer ranges from 1000 to 1900 W?m?1?K?1. Coating of the zirconium alloys surface with the described polycrystalline diamond layer serves as a zirconium alloys surface protection against undesirable changes and processes in the nuclear reactor environment.

Abstract: A foldable stroller includes a frame body, a recline adjustment mechanism and a linking component. The frame body includes a seat, a push handle, an armrest, a front leg, a rear leg, and a seatback pivoted on the seat. An end of the armrest is pivoted on the push handle, and the other end of the armrest is pivoted on the front leg and the rear leg. The armrest, an upper portion of the front leg and an upper portion of the rear leg are formed as a lateral frame. The recline adjustment mechanism is for adjusting a reclined angle of the seatback. The linking component is connected between the seatback and the lateral frame, and the lateral frame rotates upwards relative to the push handle to move the linking component upwards, so as to drive the seatback to an upright position as folding the frame body.

Abstract: Described is a radar-based method for measuring a level of material in a container. Microwaves are emitted to a surface of the material by a radar level gauge, echo waves reflected from the surface are received and the received echo waves are converted into an echo function which is stored and evaluated to establish a useful echo and to determine a position of the echo. The echo function is generated and stored with a first higher resolution for a selected first portion of the entire level measurement range of the radar level gauge. Further, the echo function is generated and stored with a second lower resolution or no echo function is generated and stored for the remaining second portion of the entire level measurement range.
