Abstract: A prosthesis including a device configured to deliver a therapeutic substance from outside a cochlea to inside the cochlea and configured to evoke a mechanically based hearing percept. In an exemplary embodiment, the device is configured to drive fluid into and out of the cochlea, thereby evoking a hearing percept.

Abstract: A method and composition are provided for backfilling the annular gap created as a tunnel boring machine advances through the ground. The fill material is comprised of two components that are combined and mixed together just prior to entering the annular gap. The first component is non-cement slurry consisting of a fluidized bed combustion ash such as coal ash. The second component consists of an alkali silicate such as sodium silicate. Additionally, ordinary Portland cement and/or metakaolin can be added to the grout composition.

Abstract: A highway marking paint is provided formed from a waterborne latex paint and porous silica beads having a pore volume in the range of 0.3 cc/g to 3.0 cc/g. The silica beads enable the paint to achieve sufficient viscosity to permit the application of a highway marking of at least 40 mil and preferably at least 120 mil. The highway marking paint can also include retroreflective glass beads. Optionally, the highway marking paint further includes an acrylic polymer emulsion. The porous silica in bead form enhances the flowability of the porous silica beads and retroreflective beads.

Abstract: Disclosed is a novel amino acid derived surfactant which is prepared by forming the salt of an alkylaminopropionic acid and a basic amino acid such as arginine which is useful in cosmetic and personal care compositions.

Abstract: A liquid preservative composition comprises (a) an alkanol fatty monoester; and (b) an aqueous isothiazolinone solution, an alkanol-substituted aromatic compound, or a combination thereof; and is free from formaldehyde, formaldehyde-releasing compounds, and paraben compounds. Preferred compositions comprise glyceryl caprylate, together with either phenethyl alcohol or an aqueous 2-methyl-4-isothiazolin-3-one solution.

Abstract: A high concentration, aqueous liquid surfactant composition is disclosed, comprising at least one amphoteric and/or anionic surfactant and a liquid-stabilizing amount of at least one liquid-stabilizing agent. The liquid-stabilizing agent is a succinic acid derivative, glutaric acid derivative or a combination thereof. The composition is pourable and pumpable at ambient room temperature.

Abstract: A method of producing wort or beer which avoids or minimizes problems encountered with high beta glucan content such as slow lautering of wort, slow filtration of beer, decreased yields, gel precipitations in the package, unfilterable beer haze, and colloidal instability. This method involves modifying the malt to an extent which reduces the beta glucan content to a sufficiently low value such that these problems are avoided or minimized sufficiently. An undesirable side effect of malting to this extent is that certain undesirable constituents, such as color components (causing the beer to be dark) and certain proteins, are formed. An adsorbent is contacted with the wort or beer to remove these undesirable constituents from the wort or beer. The adsorption step preferably utilizes clay, such as montmorillonite or bentonite, that can be readily filtered.

Abstract: Compositions for adsorbing sulfur-containing compounds and eliminating or reducing odors associated with the ingestion of foods or medicines causing sulfur odor, such as garlic and onions, contain a metal complex of a substrate and a ligand. The complex may be contained in a carrier, such as a silica gel, and has low solubility in an aqueous environment. The ligand of the compositions may comprise an amino acid containing sulfur, nitrogen, or a carboxylic acid, such as cystine, and the substrate is a metal which may be copper, zinc, or iron.

Abstract: A composition that provides improved chillproofing of beer and other beverages is disclosed. The composition comprises a silica gel reacted with a metal, said metal having the capability of being sorbed and desorbed from the silica gel in response to pH and concentration changes.

Abstract: Combinations of silica gel and magnesium silicate have been found to be effective agents to prevent the formation of haze in beer. Said haze, often called chill haze, is prevented by contacting the ruh beer with the combination to remove some or all of the components that react to form the haze. The spent combination is removed from the beer in the usual manner.
