Abstract: Thermoplastic starch-based materials formed as a reactive extrusion product from one or more starches, one or more plasticizers, and micro or nano particles or fibers, with such particles or fibers being added before gelatinization of the starch. A diacid or acid anhydride may also be included. Such components are added and then gelatinized together, before blending of a resulting starch-based polymeric material with any other polymer (e.g., polyester biopolymers, polyolefins, or the like). Addition of such nano or micro particles during synthesis of the thermoplastic starch advantageously results in a far more homogenous distribution of such particles or fibers throughout the starch-based material matrix than occurs where addition of similar particles or fibers is attempted after formation of the thermoplastic starch, e.g., when mixing with a partner resin material. Addition of a diacid during synthesis can reduce molecular weight and viscosity, further aiding in achieving substantially uniform distribution.

Abstract: The invention provides DNA compositions that relate to transgenic insect resistant maize plants. Also provided are assays for detecting the presence of the maize DAS-59122-7 event based on the DNA sequence of the recombinant construct inserted into the maize genome and the DNA sequences flanking the insertion site. Kits and conditions useful in conducting the assays are provided.

Abstract: Method and apparatus for transferring particulate matter, such as seed, from a bulk supply to planting apparatus such as a planter or drill utilizing a pneumatic conveyer system including a lightweight, portable rotary air lock for introducing the particulate matter into the pneumatic conveying system. The system further includes a blower for pressurizing the pneumatic conveyer line and a discharge device at a remote end of the pneumatic conveyor line for delivering the seed or other particulate matter directly into the seed boxes associated with the planting apparatus. An adapter is also included for coupling the lightweight rotary air lock to a bulk supply container such that the lightweight rotary air lock is held at a predetermined angle with respect to the vertical.

Abstract: A pneumatic conveyor and related method for seeds or other particulate matter comprises a cyclone or vortex type discharge device, a blower for supplying a flow of air, a conduit coupled to the blower and to the discharge device for supplying a flow of air thereto, the conduit being primarily a flexible conduit, and a venturi in the conduit for pneumatic coupling to a supply of seeds whereby the seeds may be withdrawn from a supply container into the venturi for transport with the air stream to the discharge device. The venturi is connected to the container by a component that comprises a slide gate closure between the opening of the container and the intake of the venturi.
