Abstract: Disclosed herein include antibodies or fragments thereof having specificity to a sarbecovirus spike protein. Also provided are compositions, methods, and kits for using said antibodies or fragments thereof for preventing or treating, for example a coronavirus infection.

Abstract: A frangible flying target for use in inanimate bird shooting. The target may include a body substantially formed from matter edible to animals. The body may include at least one of protein meal; urea; condensed distillers solubles; and cement. The protein meal may be encased in an edible binder. Making the target may be carried out by mixing the ingredients and curing in a desired target shape. This may be carried out by molding. In other examples, the target may be made by making a blank using molding or extrusion, and then trimming or machining the blank to the desired target shape. The mixture may comprise, by total weight of the mixture, 5-20 percent cement, 0.5-25 percent molasses, 0-10 percent salt, and 0.5-10 percent urea; and water.

Abstract: An attachment system for attaching shoes having toe and heel areas to a wide variety of sports equipment, in particular to a rowing boat or a rowing machine. The system includes an attachment device that is connected to or otherwise a part of the equipment, and a shoe block assembly that accepts the attachment device. These parts generally removably lock together for use of the equipment, which provides users custom features, better control over the force applied to the equipment via the shoe, and automatic emergency functions. An adjustment device generally fits into the shoe block assembly and is fixed to the shoe block assembly with screws or any other attachment methods, or could be formed as a part of the shoe block assembly, and the shoe block assembly is removably attachable to the attachment device by magnetic force or non-magnetic devices.

Abstract: An improved attachment system for attaching shoes having toe and heel areas to a wide variety of sports equipment, in particular to a rowing boat or a rowing machine. One embodiment of the system comprises an attachment device (1) that is connected to or otherwise a part of the equipment, and a shoe block assembly (3) that accepts the attachment device (1). These parts generally removably lock together for use of the equipment, which provides users custom features, better control over the force applied to the equipment via the shoe, and automatic emergency functions. An adjustment device (2) generally fits into the shoe block assembly (3) and is fixed thereto with screws or any other attachment means, or could be formed as a part thereof, and the shoe block assembly (3) is removably attachable to the attachment device (1) by means of magnetic force. Non-magnetic embodiments are also described.
