20140154516 | ADHESIVES DERIVED FROM AGRICULTURAL PROTEINS - The invention is directed to adhesives derived from animal or plant proteins, particularly canola and spent hen proteins. The adhesives are prepared by extracting the proteins by pH shifting; and either treating the extracted proteins with urea or sodium dodecyl sulfate, or polymerizing the proteins to form a protein-polymer conjugate. The invention is also directed to a wood based product comprising pieces of wood based material joined or consolidated with the adhesives. | 06-05-2014 |

20130065320 | METHODS FOR THE ASSESSMENT OF COLORECTAL CANCER AND COLORECTAL POLYPS BY MEASUREMENT OF METABOLITES IN URINE - Methods for the diagnosis of CRC, colorectal polyps in general and adenomatous polyps in particular by measurement of metabolites in urine are described. In some embodiments, certain metabolites are identified as being elevated or reduced in concentration or quantity in subjects with CRC and/or colorectal polyps as compared with subjects without CRC or colorectal polyps. The measurement of these metabolites in urine can indicate the presence of CRC or colorectal polyps in general or adanomatous polyps in particular in a subject. | 03-14-2013 |

20140110101 | Well Tubular, Coating System and Method for Oilfield Applications - A technique facilitates the use of polymer materials in a downhole environment via utilization of a coating that can be applied to the polymer material. The methodology enables formation of a coating that sufficiently bonds with an underlying base structure of polymer material to withstand the harsh environment encountered in a downhole application. Additionally, the coating may utilize reactive chemistries to further protect the polymer material against the ingress of deleterious fluids while located in the downhole environment. Well tubulars formed of coated polymer are also described. | 04-24-2014 |

20140101967 | OIL SANDS FLUID FINE TAILINGS DEWATERING USING RIM DITCHING - A process of dewatering tailings is provided comprising mixing the tailings with a sufficient amount of an additive or a mixture thereof; depositing the resulting mixture into a disposal area; pumping water from the deposit to one or more sumps, and allowing the deposit to reach a sufficient strength; and removing remaining deposit water and rainfall through one or more of a network of ditches, a decant tower, or a plurality of dike drainage structures to yield a non-segregating deposit for reclamation. | 04-17-2014 |
20140116521 | SUBAQUEOUS MINING TAILINGS PLACEMENT - A process for reducing segregation of mining tailings while being deposited below the surface of a column of fluid is provided which comprises introducing the mining tailings into a downpipe having an inlet at or near the surface of the column of fluid and an outlet submerged in the column of fluid; providing at least one pressure drop element in the downpipe to prevent acceleration of the mining tailings and maintain the tailings flow therethrough; and providing a diffusing device at the outlet of the downpipe to reduce the velocity of the mining tailings as the tailings are discharged therefrom. | 05-01-2014 |
20140116946 | USE OF MULTIVALENT INORGANIC ADDITIVES - A process of dewatering tailings such as fluid fine tailings from oil sand extraction is provided comprising mixing the tailings with a sufficient amount of an additive comprising at least one multivalent cation, each multivalent cation being in an amount ranging from about 0.125% to about 0.25% and higher, up to or greater than the solubility limit of the at least one multivalent cation, and depositing the resulting mixture into a containment area to yield a non-segregating, rapidly cracking and dewatering deposit for reclamation and recycle water which can optionally be used in an oil sand bitumen extraction process. | 05-01-2014 |
20140119832 | OVERBURDEN/TAILINGS MIXTURES FOR ENGINEERED TAILINGS DEPOSIT CONTROL - A process of dewatering tailings is provided comprising providing overburden having a moisture content ranging from about 15 wt % to about 25 wt % and comminuting the overburden to a first size; providing tailings having a solids content ranging from about 10 wt % to about 60 wt %; adding the tailings to the first sized overburden to form treated overburden and comminuting the treated overburden to a second size; and depositing the second sized treated overburden to produce a solidified deposit. | 05-01-2014 |
20140119833 | OVERBURDEN/TAILINGS MIXTURES FOR ENGINEERED TAILINGS DEPOSIT CONTROL - A process for enhancing the solidification of tailings is provided comprising providing overburden having a moisture content ranging from about 15 wt % to about 25 wt % and comminuting the overburden to a first size; providing tailings having a solids content ranging from about 1 wt % to about 70 wt %; adding the tailings to the first sized overburden to form treated overburden and comminuting the treated overburden to a second size; and depositing the second sized treated overburden to produce a substantially solidified deposit. | 05-01-2014 |
