Abstract: The present disclosure relates to a waveguide gasket arrangement arranged for electrically sealing a waveguide interface between a first waveguide end and a second waveguide end, where the waveguide gasket arrangement comprises a first plurality of electrically conducting members connected to a first common structure along a first circumference. The waveguide gasket arrangement further comprises a second plurality of electrically conducting members connected to a second common structure along a second circumference.

Abstract: Nicotine permeability through the mucous membrane depends on pH, with the uptake improving with higher pH. The invention provides stabilization of basic pH at the surface of the product during oral use thereof, without reducing nicotine mobility within the oral smokeless tobacco or nicotine-containing non-tobacco product. The invention in one aspect relates to an oral smokeless tobacco or nicotine-containing non-tobacco product comprising a composition enclosed by a wrapping material, wherein the wrapping material comprises a magnesium carbonate. In another aspect, the invention relates to an oral smokeless tobacco or nicotine-containing non-tobacco product comprising a composition enclosed by a wrapping material, and comprising a liner adjacent to the wrapping material, wherein the liner comprises magnesium carbonate in an amount of 0.1 to 10%, by total weight of the oral smokeless product.

Abstract: A smokeless tobacco composition comprising at least one type of non-tobacco fibers, wherein the non-tobacco fibers have an average length-to-width ratio equal to or greater than 3.5:1 and equal to or lower than 100:1, and a method for manufacturing the smokeless tobacco composition.

Abstract: A smokeless tobacco or non-tobacco snuff composition for oral use comprising at least 20 wt % water based on the total weight of the final composition and at least 1 wt % lactic acid or a salt thereof based on the dry weight of the final smokeless tobacco or non-tobacco snuff composition, as well as a method for its manufacture and the use of such composition.
