Abstract: Pesticidal proteins are provided that combine two or more modes of action into a single molecule. These pesticidal proteins therefor exhibit greater efficacy and/or durability of resistance, for the purposes of pest control, and can be utilized for pest control by provision in the diet of a pest organism, or by topical application to crop plants and/or pests. Methods and compositions for producing and using such proteins are also provided.

Abstract: A refrigeration system having a container with at least two different temperature cooling zones separated by a divider. The divider has a wall and a partition spaced apart from each other. The partition has a heat transfer plate with a sheet with a heat transfer substance attached thereto. The refrigeration system may be cooled by a variable capacity compressor system having refrigeration and hot-gas defrost modes. The system is defrosted by circulation of gas therethrough. A controller may be engaged to and selectably operate the compressor system.

Abstract: Cis-polyunsaturated fatty acids stimulate taste receptor cells in the mouth. The addition of free fatty acids to foods, such as low calorie fat substitutes or sugar substitutes, can make the foods more palatable. Certain ion channels in taste receptor cells are directly sensitive to extracellular applications of free fatty acids. Free fatty acids inhibit the "delayed rectifying potassium channel" in taste receptor cells. Fatty acids exhibiting these properties are those having at least two double bonds, at least one of which is in the cis confirmation, i.e., cis-polyunsaturated fatty acids. The time for taste receptor cells to return to the "resting" state is longer following fatty acid stimulation than for other taste stimuli, thus increasing the taste receptor cell sensitivity to other stimuli, i.e., sugar or other sweet stimuli.
