Abstract: Disclosed herein are methods for inducing immunity against a virus such as a coronavirus in the mucosal tissue of a patient, include administering a vaccine composition to the patient by oral administration (e.g., nasal injection, nasal inhalation, oral inhalation, and/or oral ingestion). Also disclosed are compositions for assaying the presence of anti-viral antibodies induced by the administered vaccine or the presence of viral proteins in a saliva sample include a stabilizing solution and may also include the use of aragonite particle beads. Compositions and methods are presented for prevention and/or treatment of a coronavirus disease wherein the composition comprises comprises a recombinant entity. The recombinant entity is bivalent, comprising a nucleic acid encoding a coronavirus 2 nucleocapsid protein CoV2 nucleocapsid protein fused to an endosomal targeting sequence, and a nucleic acid encoding a CoV2 spike protein sequence optimized for cell surface expression.

Abstract: An apparatus for creating solid or liquid nanoparticles having a nozzle to create a first particle size from a bulk liquid flow that is in fluid communication with a gas flow amplifier comprising an inlet cone connected to and in fluid communication with the inlet of a cylindrical housing; a diffuser connected to and in fluid communication with the outlet of said housing; and said housing comprising at least two rings of ports disposed of along a circumference of the cylindrical housing; and a means to inject compressed gas into the housing through said ports.

Abstract: A pet feeding device for deterring spillage during eating and drinking includes a bowl, which is positionable on a substantially horizontal surface and is at least partially filled with contents. A lip is engaged to a rim of the bowl and extends inwardly therefrom. The lip deters spillage of contents of the bowl during feeding and drinking therefrom by a pet.

Abstract: Curing method and apparatus for curing the lining (4) of a pipe (3) and which comprises a traveling frame (2) for introduction into the pipe (3), a curing device (8) mounted on the frame (2) and operative to cure the inner wall of the lining during travel of the frame along the pipe, and a fluid pressure driven propelling device (11) connected to the frame (2) and operative, upon application of fluid pressure to the pipe, to pull the frame along the pipe.

Abstract: A method of re-lining a main pipeline having at least one transversely extending pipe connected thereto via a generally annular connection region includes applying an internal lining to the inner wall of a length of the main pipeline and which overlies the entrance to the transversely extending pipe. A hole is then formed in the lining so as to expose the entrance. A re-lining assembly is introduced into the pipe from an end thereof remote from the entrance, the assembly comprising a tubular web of resin-permeated material within an elastomeric membrane which is everted by application of fluid pressure to the assembly so as to introduce the assembly into the pipe and so that the now externally located tubular web projects into the main pipeline. Fluid pressure is further applied to the assembly so that the membrane causes the projecting end of the tubular web to flare or deform outwardly and thereby overlie the connection region.
