Abstract

Disclosed herein are processes of making furan-based polyamides using solvent-free melt condensation of a diamine and an ester derivative of 2,5-furandicarboxylic acid with a C2 to C12 aliphatic diol or a polyol. The processes comprise a) forming a reaction mixture by mixing one or more diamines, a diester comprising an ester derivative of 2,5-furandicarboxylic acid with a C2 to C12 aliphatic diol or a polyol, and a catalyst, such that the diamine is present in an excess amount of at least 1 mol% with respect to the diester amount; and b) melt polycondensing the reaction mixture in the absence of a solvent at a temperature in the range of 60 °C to a maximum temperature of 250 °C under an inert atmosphere, while removing alkyl alcohol to form a furan-based polyamide, wherein the one or more diamines comprises an aliphatic diamine, an aromatic diamine, or an alkylaromatic diamine.

Abstract

Compositions and methods for controlling pests are provided. The methods involve transforming organisms with one or more nucleic acid sequence encoding insecticidal protein(s) and one or more silencing element(s). In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The molecular and breeding stacks find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.

Abstract

Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Coleopteran plant pest or a Diabrotica plant pest decrease the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides set forth in any one of SEQ ID NOS: 1-236 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity). Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. In specific embodiment, the pest is D. virgifera virgifera, D. barber i, D. speciosa, or D. undecimpimctata howardi, Plants, plant part, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.

Abstract

Abstract of the Disclosure Pharmaceutical compositions of nalbuphine and non-narcotic analgesic compounds such as ibuprofen, zomepirac, indomethacin, tiflamizole, sulindac, and flurbiprofen have been found to exhibit unexpectedly enhanced analgesic activity by applying an analysis model which considers data characterizing the anal- gesic effect of both the pure components as well as the fixed dose ratio combinations. This synergism enables the use of lower doses of either or both drugs with a concomitant reduction in risk of possible side effects.

Abstract

ABSTRACT OF THE DISCLOSURE Certain N,N'-ethylenebisamides and N,N' diadipamides added to ethylene/vinyl acetate dipolymers, terpolymers with carbon monoxide, copolymers of ethylene with methacrylic acid, and copolymers of ethylene with methyl methacrylate remarkably reduce the tendency of polymer pellets to block. Free-flowing copolymer pellets can be handled without blocking and moved more quickly through the packing equipment and can be stored for extended periods without blocking. Copolymer pellets containing these additives can be packed into large containers and shipped without blocking. The preferred additive is N,N'-ethylenebis- oleamide.

TITLE Sterile Docking Process, Apparatus and System ABSTRACT A process, apparatus and system for making a sterile connection between two thermoplastic resin tubes is disclosed. The tubes are severed by an array of hot wires so as to form molten tube ends. The array is maintained at a temperature such that ambient air immediately within the vicinity of urging is kept sterile. Then, the tubes are aligned with each other and urged together. As the thermoplastic resin cools a sterile weld is formed.

Abstract

TITLE Sterile Docking Process, Apparatus and System ABSTRACT A process, apparatus and system for making a sterile connection between two thermoplastic resin tubes is disclosed. A hot stream of fluid is urged either through both aid tubes transversely of the axis of each tube or through opposing side sections of the tubes substantially perpendicular to the axes of the tubes to form continuous contact between the hot fluid stream, the interior of the tubes and molten tube portions thereby formed. The tubes are aligned with each other, if necessary, and urged together while the hot fluid stream is removed. As the thermoplastic resin cools a sterile weld is formed.
