Abstract: An absorbent undergarment with a tunable absorbent portion. The tunable portion being tunable to absorb and/or capture both fluid materials as well as more viscous, solid, and/or semi-solid materials. Thus, the undergarment affords the user improved wearability as well as comfort and avoids unwanted odors from exposed material.

Abstract: A foodstuff is located in a container open at its top end in which ambient gas (air) occupies the space inside the container above the product. The container is immersed into a liquid having a low dielectric loss factor, such as water, to such an extent that the liquid level is somewhat below the upper side of the product in the container. Using electrodes located to either side of the container, there is passed through the container from one side thereof to the other a first high-frequency electromagnetic alternating field having a respective first frequency such that the penetration depth of said first field is at least as great as the width of the container.

Abstract: An organic product is located in a closed container in which a gas occupies the space inside the container above the product. The container is immersed into a liquid having a low dielectric loss factor, such as water, to such an extent that the liquid level is somewhat below the upper side of the product in the container. Using electrodes located to either side of the container, there is passed through the container from one side thereof to the other a first high-frequency electromagnetic alternating field having a respective first frequency such that the penetration depth of said first field is at least as great as the width of the container.
