  • Publication number: 20210100268
    Abstract: A method is disclosed for making palatable methionine-restricted foods, to deliver a methionine-restricted diet to human or veterinary patients. A protein or a food product containing protein is partially oxidized, preferably with ozone, to oxidize nearly all of the methionine and cysteine. After oxidation, tryptophan and lysine are optionally added back since they tend to be oxidized also. Optionally, a small amount of methionine is also added back so that the final methionine is within a preferred range of about 0.85 to about 1.8 gram methionine per 100 gram total protein, preferably about 1.2 gram per 100 gram total protein.

  • Patent number: 10954390
    Abstract: The low temperature cracking and high temperature rutting of polymer-modified asphalt concrete pavement can be reduced. The composite includes asphalt and at least one polymer that expands at low temperature, triggered by cooling-induced tensile stress, to reduce thermal cracking. The composite includes at least one polymer that expands at high temperature, so that the composite recovers after compression induced by traffic loading at higher temperatures, thereby reducing rutting. The system reduces thermal stress, and reduces or even eliminates thermal cracking and rutting. Shape memory polymers (SMPs) are used to improve asphalt compositions so that they better resist both thermal cracking and rutting. The SMP(s) can be incorporated into the asphalt, or a portion of fine aggregates can be replaced with SMP particles or SMP fibers, or aggregate replacement and asphalt modification can be combined.

  • Patent number: 10952974
    Abstract: Methods and compositions are disclosed for delivering lutein or other antioxidant to target tissues such as the eye, in bioactive form, while protecting the antioxidant from degradation. The antioxidant is encapsulated in nanoparticles comprising a protein such as zein or a polymer such as poly(lactic-co-glycolic acid) (PLGA). Preferably a surfactant is associated with the nanoparticles as well, further helping to protect the antioxidant. After the nanoparticles are administered to the target tissue, bioactive antioxidant is released to the tissue over time. Optionally, the nanoparticles are admixed with a thermosensitive, bioadhesive gel to promote slow release of antioxidant. The methods and compositions are useful for treating or preventing conditions such as age-related macular degeneration or cataracts.

  • Publication number: 20210080389
    Abstract: Embodiments of the present application are directed toward a focusing Schlieren technique that is capable of adding color-coded directional information to the visualization of density gradients. Other advantages of the technique can include that it does not require manual calibration, has a simple design and is sensitive enough to be used in compact experimental setups. Certain embodiments include the use of a color-coded source image that replaces the conventional source grid. The technique may benefit from a computer-controlled digital background, which is used for both illumination and display of color-coded source images.

  • Publication number: 20210068398
    Abstract: A composition and method for killing feral hogs: a bait that is attractive to hogs is mixed with a lethal amount of sodium nitrite, along with sufficient base to inhibit decomposition of the sodium nitrite. At sufficiently high pH, encapsulation of the sodium nitrite is not required to inhibit decomposition. In the absence of substantial decomposition, the sodium nitrite itself is not aversive to the pigs, and may even enhance acceptance of the baits by the pigs. Optionally, an anti-emetic compound is added to the mixture to reduce the likelihood the bait will be vomited. Optionally, an additional toxicant such as luteolin is added to the mixture.

  • Patent number: 10934381
    Abstract: A sealant composition and method for its manufacture are disclosed. A two-way shape memory polymer (2W-SMP) sealant expands upon cooling and contracts upon heating, and thus provides improved sealing for pavements and other structures. The base resin for the sealant is polybutadiene with a high cis content. Uses for the sealant include, but are not limited to: sealant for expansion joint, contraction joint, or construction joint in cement concrete pavement; sealant or sealer for transverse cracks or block cracks in cement concrete pavement or asphalt concrete pavement; sealant for pipelines, lightweight composite structures, roofs, buildings, bridge decks, dams, offshore platforms; sealant for other structures and devices that have previously typically used polymer sealants.
