Abstract: Molding apparatus (10) is provided which allows use of a particulate non-liquid molding material (121) to produce a variety of articles, such as frustoconical barrel segments (122). The apparatus (10) includes a female mold segment (18) including generally annular inner and outer sidewalls (70, 76) and a complemental male mold section (20) having an annular sidewall unit (30). In use, a molding material (121) is placed between the sidewalls (70, 76) and the section (20) is shifted so that it telescopes within the section (18); this compresses the material (121) to a desired final shape, which is then hardened to yield the final product (122). An optional wear insert (26) can be used with female mold section (18), which can be replaced as needed and assists in cleaning of the apparatus (10).

Abstract: A method of forming ligated nanoparticles of the formula Y(Z)x where Y is a nanoparticle selected from the group consisting of elemental metals having atomic numbers ranging from 21-34, 39-52, 57-83 and 89-102, all inclusive, the halides, oxides and sulfides of such metals, and the alkali metal and alkaline earth metal halides, and Z represents ligand moieties such as the alkyl thiols. In the method, a first colloidal dispersion is formed made up of nanoparticles solvated in a molar excess of a first solvent (preferably a ketone such as acetone), a second solvent different than the first solvent (preferably an organic aryl solvent such as toluene) and a quantity of ligand moieties; the first solvent is then removed under vacuum and the ligand moieties ligate to the nanoparticles to give a second colloidal dispersion of the ligated nanoparticles solvated in the second solvent. If substantially monodispersed nanoparticles are desired, the second dispersion is subjected to a digestive ripening process.

Abstract: An expansion or crack joint assembly (32) utilizes a coupler (20) with or without a bottom sheet (34) to join adjacent roadway concrete slabs (86, 90) formed separately initially or continuously cast and later separated by a saw cut, which induces cracking to form a crack joint. The coupler (20) includes a casing (22), an internal component (24,25,62,65), and outer sleeve (26), and end caps (28,30). The casing (22) defines an internal chamber (40) which receives the internal component (24,25,62,65) therein. The sleeve (26) and end caps (28,30) fit over the casing (22). The casing (22) and sleeve (26) transmit loads between the concrete slabs (86,90) while the sleeve (26) and end caps (86,90) operate to reduce stress concentrations. The bottom sheet (34) inhibits water from entering the expansion or crack joint assembly (32) from below, if used, and prevents pumping.

Abstract: A feedstuff with reduced ruminal protein degradability is prepared by mixing a carbohydrase enzyme with a material suitable for livestock feed and steeping the mixture under suitable conditions for the carbohydrase enzyme to hydrolyze carbohydrates contained within the material to reducing forms. The mixture is then heated to induce browning so that the protein contained within the material is rendered inert to ruminal degradation. The carbohydrase enzyme may be supplied to the steeping step by the addition of a microorganism capable of secreting the enzyme. A method of feeding a feedstuff with reduced ruminal degradability is also provided.

Abstract: Modified soy protein adhesives are provided which have increased bonding abilities. The adhesives are prepared by forming a dispersion of soy protein, water, and a modifier selected from two classes of modifiers. The preferred modifiers are urea, sodium dodecylbenzene sulfonate, sodium dodecyl sulfate, and guanidine hydrochloride. The resulting dispersion is stirred, freeze-dried, and milled into a powder to be stored until use. The adhesives of the invention have superior bonding qualities while being safe for the environment. The urea-modified, GH-modified, SDS-modified, and SDBS-modified soy protein adhesives have higher water resistance than non-modified soy protein adhesives.

Abstract: The proposed holographic particle image velocimetry (HPIV) system employs holograms of two time-separated particle fields, illuminated by separate reference beams on a single recording medium. 90-degree scattering is utilized for the object wave, in order to improve Numerical Aperture and resolve the third dimension of the hologram. The proposed HPIV system then uses substantially the same optical geometry for the reconstruction process. A CCD camera is utilized to extract particle subimages, thin slice by thin slice, and a centroid-finding algorithm is applied to extract centroid locations for each volume. The concise cross correlation (CCC) algorithm for extracting velocity vector fields from the centroid data is an important enabling feature of the proposed system. Correlations are calculated between subsets of centroids representing the images or cubes, and velocity vectors are computed from the individual correlations.

Abstract: The present invention relates to a method of feeding carnitine supplemented diets to sows during the period of gestation or during both gestation and lactation periods. The method enhances pork productivity by increasing litter and pig birth and weaning weights, reducing the number of stillborn pigs and increasing the number of pigs born alive in the subsequent reproductive cycle. Sow diets of this invention include carnitine, such as L-carnitine or L-carnitine salts. Carnitine is generally added to the swine feed formulation in the amount of from about 5 to about 5,000 ppm.

Abstract: A micro-size LED-like optical element has an n-contact, a p-contact, and an optical active structure connected between the n-contact and the p-contact for generating light when forward biased and for detecting light when reverse biased. The optical active structure has a diameter of about 20 &mgr;m or smaller. When the the optical active structure is forward biased, it forms a micro-size LED (&mgr;LED). When the optical active structure is reverse biased, it forms a micro-size detector (&mgr;detector). An array of the micro-size optical active structures may be used as a minidisplay, a detector, or a sensor (when each structure is separately wired), or as a hyperbright LED (when the structures are wired to turn on and off simultaneously). Alternatively, a hyperbright LED may be obtained by forming a plurality of micro-size holes extending into an LED wafer.

Broadly, the methods comprise mixing a source of phosphorus and an oxide of manganese with the contaminated soil so as to reduce the metal bioavailability in the soil. The phosphorus source and oxide of manganese can be individually mixed with the soil, or can be provided as a premix powder or granule to be mixed with the contaminated soil. Preferably, the pH of the soil is then adjusted to, and maintained at, a level of at least about 7.0. Preferred phosphorus sources include phosphate rock, alkali and alkaline earth metal phosphates, ammonium phosphates, ammonium orthophosphates, orthophosphoric acid, and superphosphates. Preferred oxides of manganese include MnO2, Mn3O4, birnessite, cryptomelane, and psilomelanes.

Abstract: A high capacity grain aeration apparatus (10) is provided which includes opposed, upright, tubular, ported inlet and outlet ducts (24,26) positioned within a grain bin (12) and having inlet and outlet fans (28, 30) adjacent the upper ends of the ducts (24, 26). The ducts (24, 26) preferably present smooth, uncorrugated walls (40, 44).

Abstract: Reversible swellable modified starch products are provided in the form of individual, chemically cross-linked starch granules capable of undergoing multiple hot or cold water swelling/drying cycles without losing the individuality of the starch granules, and with essentially no loss of starch solubles. The starches are prepared by forming a dispersion of starch granules in water, with the granules undergoing swelling and having a crystalline phase; a cross-linker (preferably a phosphorylating agent) is added to the dispersion in order to cross-link the starch under conditions to avoid complete gelatinization thereof. The swollen/cross-linked starch granules are then heated in excess water in order to melt the crystalline phase of the granules. The granules exhibit a network-like structure with internal voids.
