Patent CA-2588344-A1 (CA)
Inventor: COHEN ALEJANDRO
IPC: C07K7/08
Filed: 2007-05-24
Abstract: The present invention is directed to a simple method for absolute quantification of plasma vitellogenin from two or more different fish species such as Rainbow trout and Atlantic salmon, or Atlantic cod and haddock. In the case of Rainbow trout and Atlantic salmon, plasma samples obtained from control and .beta.-estradiol induced fish were digested with trypsin. A characteristic 'signature peptide' was selected and analyzed by high performance liquid chromatography coupled to an electrospray quadrupole-time-of-flight tandem mass spectrometer, using a deuterated homologue peptide as an internal standard. The hybrid tandem mass spectrometer was operated in a 'pseudo' selected reaction monitoring mode by which three diagnostic product ions were monitored for identification and quantification purposes. The reproducibility (coefficient of variation ~5%) and sensitivity (limit of quantification of 0.009 mg/mL) achieved by this simple assay allow it to be considered as an alternative to immunological assays. In the case of Atlantic cod and haddock, the amino acid sequence of the vitellogenin protein has not yet been determined, but, the Atlantic cod vitellogenin has been characterized using a 'bottom-up' mass spectrometric approach. Vitellogenin synthesis was induced 'in vivo' with .beta.-Estradiol, and subjected to trypsin digestion for characterization by matrix-assisted laser desorption/ionization-Quadrupole-Time-of-flight tandem mass spectrometry. A peptide mass fingerprint was obtained and 'de novo' sequencing of the most abundant tryptic peptides was performed by low energy collision induced dissociation-tandem mass spectrometry. Thus, the sequences of various tryptic peptides have been elucidated. It has also been determined that Atlantic cod vitellogenin shares a series of common peptides with the two different known vitellogenin sequences of Haddock, a closely related species. There are also disclosed novel isolated signature peptides, namely Thr-Tyr-Phe-Ala-Gly-Ala-Ala-Ala-Asp-Val-Leu-Glu-Val-Gly-Val-Arg, Asp Leu Gly Leu Ala Tyr Thr Glu Lys, Phe Phe Gly Gln Glu Ile Ala Asn Ile Asp Lys, Glu Ile Val Leu Leu Gly Tyr Gly Thr Met Ile Ser Lys and Tyr Glu Ser Phe Ala Val Ala Arg.

Inventor: KIVEKAES ERKKI
IPC: D21C7/12
Filed: 2005-12-22
Abstract: The quality of the raw material in a pulping process, wood chips, varies due to variations in its origin. The variation in chip quality will result in variations in the cooked pulp as well as problems in the operation of a digester. The control of the digester takes place by feed-back control so that the process values in the digester are adjusted by measuring the quality of the produced pulp. The residence time of the pulp in the digester is several hours so that a corrective action affects the pulp quality with considerable delay. Conditions for a successful and economic cook are a correct cooking chemical dosage, correct concentrations of impregnation and cooking liquor, accurate control of the residence time and the temperature of the cooking process as well as accurate control of the flows in a chip column in relation to the flow properties of the chip column. In a method according to the invention, the size and shape of the chip pieces supplied to a cooking plant are measured, from the measured values the factors indicating the size and the shape of the chip particles are calculated, and the process values for the digester are anticipatorily controlled by means of a mathematical model, which model includes calculating the degree of packing in the digester and the dependency of the flow resistance of the liquid flowing through the chip column on the size and shape of the chip pieces. In the model, the Ergun equation among others is used, which equation expresses the pressure loss during the flow of a liquid through a volume filled with solid bodies.

Title: System and method for bleeding off pressure following servicing of a well
Inventor: DAY MARK ALEXANDER
IPC: E21B21/08
Filed: 2007-07-20
Abstract: A technique facilitates release of pressure from a well, and/or surface treating lines, via a bleed-off mechanism. The bleed-off mechanism is in fluid communication with a flow path extending from a wellhead valve or wellbore and designed for connection with a vacuum truck. The bleed-off mechanism can be opened to enable venting of trapped pressure from the wellbore and/or flow path. The bleed-off mechanism is also designed to contain any liquid that escapes during release of the trapped pressure. Once the pressure is relieved, the vacuum truck can be used to clean out fluid from the wellbore and/or surface treating lines without exposure to excess pressure.
