| 20080281033 | Long fiber reinforced composites - A composite comprising from about 20 to 40 weight % of fiber reinforcing having a nominal length of not less than 1.25 cm, from about 1 to 10 weight % of a polar polymer and from 79 to 50 weight % of a polyolefin prepared using a single site catalyst has improved physical properties over comparable compositions made using polyolefins made using Ziegler Natta catalysts. The composites are suitable in many applications including construction and particularly in making concrete forms. | 11-13-2008 |
| 20080289274 | Half panel - The present invention provides a half panel having on its back ribs defining symmetrically complimentary closed wall open faced cells and ribs having spaces there between. The half panel may be placed in back to back relationship and rotated through a required degree of rotation so that the open faced closed wall cells and ribs having spaces there between interlock so the open faced closed wall cells have at least one diagonal cross member. This provides a rigid panel suitable for a number of applications including forms for pouring concrete. | 11-27-2008 |

| 20090170719 | SUPERIOR HYBRIDIZATION PROBES AND METHODS FOR THEIR USE IN DETECTION OF POLYNUCLEOTIDE TARGETS - We describe new hybridization probes and methods for their use in detection, identification, and quantitation of polynucleotides such as RNA and DNA. Ordinary short oligonucleotide probes usually provide higher sequence-specificity but lower efficacy of hybridization than longer ordinary polynucleotide probes where both are fully complementary to the target polynucleotide. Our new polynucleotide probes combine the hybridization efficacy of long probes with the sequence-specificity of short probes. The polynucleotide probes contain a target binding domain and a binding enhancer domain, where the binding enhancer domain does not for stable structures under hybridizing conditions with the target binding domain or its corresponding target. These binding enhancer domains are able to improve the hybridization features of the target binding domain as well as the signal-to-noise ratio for target detection. Detection methods based on these probes allow fast, accurate, and sensitive detection of target polynucleotides (either qualitatively or quantitatively) and can be easily multiplexed. | 07-02-2009 |
| 20100112686 | SHORT HAIRPIN RNAS FOR INHIBITION OF GENE EXPRESSION - Methods, compositions, and kits that include small hairpin RNA (shRNA) useful for inhibition of gene expression, such as viral-mediated gene expression, are described. | 05-06-2010 |

| 20100062054 | LIPOBEADS AND THEIR PRODUCTION - Lipobeads (liposome-encapsulated hydrogels) combine properties of hydrogels and liposomes to create systems that are sensitive to environmental conditions and respond to changes in those conditions in a fast time scale. Lipobeads may be produced by polymerizing anchored or unanchored hydrogels within liposomes or by mixing anchored or unanchored hydrogels with liposomes. Giant lipobeads may be produced by shrinking unanchored nanogels in lipobeads and fusing the resulting lipobead aggregates, long-term aging of anchored or unanchored lipobeads, or mixing anchored or unanchored aggregated nanogels with liposomes. Poly(acrylamide), poly(N-isopropylacrylamide), and poly(N-isopropylacrylamide-co-1-vinylimidazole) lipobeads were produced and characterized. | 03-11-2010 |

| 20110089829 | LOW-VOLTAGE, MULTI-BEAM KLYSTRON - A low-voltage, multi-beam, multi-MW RF source that operates at a voltage less than or equal to approximately 60 kV and generates at least one MW. The RF source includes a cathode configured to generate a plurality of beamlets. An input cavity and output cavity are common to the plurality of beamlets. A plurality of gain cavities are provided between the input and output cavities, each having a plurality of openings corresponding to the plurality of beamlets. The power source may further include a plurality of cathodes, each cathode generating a plurality of beamlets, wherein the input and output cavities are common to the plurality of beamlets from each of the plurality of cathodes, and a separate set of gain cavities are provided for each cathode. A single cathode version generates approximately 2.5 MW, and a four cathode version having four independent cavity systems and a common magnetic system generates approximately 10 MW. | 04-21-2011 |
