Title: Removal of nitrogen oxides from gas streams
Inventor: STERN SIDNEY SIMON
IPC: B01J29/072
Filed: 1997-05-28
Abstract: Temperature rise during the exothermic reduction of nitrogen oxides contained in a carbon dioxide-rich gas stream to nitrogen by contacting the gas stream with ammonia in a reactor containing a reduction catalyst is controlled by recycling a portion of the gaseous effluent from the reactor to the gas stream prior to its introduction into the reactor, thereby cooling the reactor contents without diluting the carbon dioxide in the effluent.
Patent CA-2209577-A1 (CA)

IPC: C12S3/12
Filed: 1997-07-02
Abstract: Aspergillus awamori glucoamylase [1,4-.alpha.-D-glucan glucohydrolase, EC 3.2:1.3] (GA) catalyzes the release of glucose from the non-reducing ends of starch and related oligosaccharides.  GA is used in, and defines the rate limiting step of, the commercial production of high glucose syrups.  GA is rapidly and irreversibly inactivated at temperatures above 65°C.  Based on the known GA structure and homology with other GA's, four proline substitution mutations were constructed and expressed in Saccharomyces cerevisiae.  These mutations were designed to increase GA thermal stability by decreasing conformational entropy of unfolding.  None of the mutations decreased enzyme activity.  Three of the mutations, Asp293-Pro, Asp345-Pro and Glu408-Pro, either decreased or did not significantly alter GA. However, one of the mutations, Ser30-Pro, significantly decreased the rate of irreversible thermal inactivation when analyzed between 65° and 80°C.  At 70°C a 1.9-fold decrease in thermal inactivation rate coefficients was seen and the activation energy for thermal inactivation (.DELTA..DELTA.G~) was increased by 2.2 kJ/mol. relative to wild-type GA.  Additionally, when the Ser30-Pro mutation was combined with a previously characterized stabilizing mutation (Gly137-Ala, which increased the.DELTA..DELTA.G~ by 1.3 kJ/mol. at 70°C) a 4.0 kJ/mol increase in .DELTA..DELTA.G~ relative to wild-type GA at 70°C was seen without loss of enzyme activity.

Title: Method and apparatus for receiving cdma radio communication
Inventor: TAKAGI HIROFUMI
IPC: H04B1/707
Filed: 1997-07-16
Abstract: A receiving method using a CDMA radio receiver with a plurality of receiving fingers each composed of a code generator, a correlator and a detector.  In a visited cell search while in the ON-state of the power supply, different long-period spreading codes are set in the code generators, and if none of correlated outputs from the correlators respectively corresponding to the code generators exceed a threshold value, then new different long-period spreading codes are set in the code generators.  If any one of the correlator outputs exceeds the threshold value, the mobile station is decided as staying in the cell corresponding to the long-period spreading code set in that correlator, and this long-period spreading code and time points at which peaks of correlator outputs were obtained with the long-period spreading code are set in the receiving fingers in descending order of the magnitude of correlation peaks.

Title: Nouveau gene lie a l'hypertension regule par le calcium
Inventor: HAMET PAVEL
IPC: A61K38/00
Filed: 1997-06-23
Abstract: L'invention porte sur un nouveau gène présentant une expression spécifique à certains tissus et une expression accrue dans un milieu à faible concentration en calcium. L'hypertension à faible rénine se caractérise par un abaissement du niveau de calcium sérique ionisé lié à un accroissement du niveau d'hormone parathyroïde. On admet comme hypothèse que le ou les facteurs d'hypertension sont cosécrétés avec la protéine liée à l'hormone parathyroïde (PTH) chez le rat spontanément hypertendu (SHR), le facteur parathyroïdien d'hypertension étant l'un d'entre eux. Cette invention identifie les gènes exprimés différentiellement dans des modèles humains et murins hypertension à faible rénine (SHR) et dans des modèles murins à normotensifs induits par de faibles niveaux de calcium dans la glande parathyroïde. L'ADNc d'un gène humain et l'ADNc d'un gène murin exprimés par les cellules de la glande parathyroïde ont été clonés et séquencés sans avoir trouvé de forte homologie dans les banques de gènes. Leur expression est plus élevée dans les modèles d'hypertension et renforcée par l'incubation des cellules dans un milieu à faible concentration en calcium. L'hybridation in situ a mis en évidence l'expression spécifique de gènes dans les médullosurrénales et les corticosurrénales, les tubes proximaux et la parathyroïde avec de très bas niveaux dans les ventricules du coeur, la substance médullaire du rein, les glomérules, et le foie. Ces nouveaux gènes régulés par le calcium présentent une expression spécifique à certains tissus et une expression accrue en cas d'hypertension.

IPC: C08K3/02
Filed: 1998-03-04
Abstract: The polymeric composition for radiation shielding includes a resinous binder with a radiation absorbing material suspended substantially homogeneously throughout the resinous binder.  A thixotropic agent is dispersed within the resinous binder to act as a suspending agent.  The thixotropic agent is present in an amount sufficient to substantially suspend the absorbing material in the resinous binder.  The thixotropic agent acts to maintain a homogeneous dispersion of large amounts of radiation absorbing material before and during the resinous binder curing or setting process.  In some embodiments, the thixotropic agent also acts as a supporting or reinforcing agent, thereby adding to the strength and stability of the shielding material after the resinous binder cures.  In certain embodiments, the radiation absorbing material can comprise up to about 95% by weight of the total composition, or up to about 66% by volume of the total composition.  In some formulations, the mixed material may be applied by hand to encapsulate sources of radiation or to repair dents or holes in existing shielding material.  In other formulations, the mixed material may be injected into molds or fed into extruders to obtain desired shapes.
