Patent CA-2457754-C (CA)
Title: Terminal-phosphate-labeled nucleotides and methods of use
Inventor: NELSON JOHN
IPC: C12Q1/42
Filed: 2002-08-29
Granted: 2012-06-19
Abstract: The present invention describes methods of detecting a nucleic acid in a sample, based on the use of terminal-phosphate-labeled nucleotides as substrates for nucleic acid polymerases. The methods provided by this invention utilize a nucleoside polyphosphate, dideoxynucleoside polyphosphate, or deoxynucleoside polyphosphate analogue which has a colorimetric dye, chemiluminescent, or fluorescent moiety, a mass tag or an electrochemical tag attached to the terminal-phosphate. When a nucleic acid polymerase uses this analogue as a substrate, an enzyme-activatable label would be present on the inorganic polyphosphate by-product of phosphoryl transfer. Cleavage of the polyphosphate product of phosphoryl transfer via phosphatase leads to a detectable change in the label attached thereon. When the polymerase assay is performed in the presence of a phosphatase, there is provided a convenient method for real-time monitoring of DNA or RNA synthesis and detection of a target nucleic acid.

Abstract: La présente invention concerne des catalyseurs pour la synthèse de l'ammoniac, à base de ruthénium, supporté directement sur du graphite d'une surface spécifique BET dépassant 10 m?2¿/g, de dépassant préférence 100 m?2¿/g, et encore mieux, dépassant 280 m?2¿/g. Ce graphite est caractérisé par un diagramme de diffraction aux rayons X contenant des lignes de diffraction caractéristiques uniquement du graphite cristallin à l'exclusion des bandes correspondantes imputables au carbone amorphe. On peut ajouter comme promoteurs à ces catalyseurs du baryum, du césium et du potassium. Ces supports graphiteux permettent d'éviter les traitements a priori et a posteriori indispensables dans le cas de supports obtenus par graphitisation partielle des carbones actifs. En outre, pendant l'utilisation ils ne sont affectés que de façon négligeable par méthanation dont font preuve les supports obtenus à partir des carbones actifs. Enfin, les catalyseurs de l'invention sont caractérisés par une activité très haute, même avec des charges de ruthénium bien en dessous de la charge connue.
Patent CA-2469817-C (CA)
Inventor: YANG CHANGHUEI
IPC: G01B11/00

Granted: 2012-02-14
Abstract: La présente invention concerne des procédés faisant appel à une technique précise fondée sur les phases pour la mesure d'au moins une caractéristique d'un objet à mesurer. Une telle caractéristique peut être une longue distance arbitraire, par exemple, mesurée de préférence avec une précision d'un ordre inférieur au nanomètre. Selon un mode de réalisation préféré de l'invention, on utilise un interféromètre, par exemple un interféromètre de Michelson, comportant des sources lumineuses harmoniquement associées, une à onde continue (CW) et une seconde source présentant une faible cohérence (LC). La source à faible cohérence émet une lumière d'une largeur de bande spectrale qui est de préférence supérieure à 5 nm pour une longueur d'onde d'un micron (µ), par exemple, bien que cette largeur de bande puisse varier en fonction de la longueur d'onde et de l'application. En réglant légèrement la longueur d'onde centrale de la source à faible cohérence entre des balayages de l'objet à mesurer tel qu'un échantillon cible, on peut utiliser la relation de phases entre les signaux hétérodynes de l'onde continue et de la lumière à faible cohérence pour mesurer la séparation séparant des surfaces ou interfaces réfléchissantes, cela avec une précision d'un ordre inférieur au nanomètre. Etant donné que cette technique est complètement exempte d'ambiguïté 2 .pi., défaut dont souffrent la plupart des techniques fondées sur les phases, elle peut être mise en oeuvre pour la mesure, sans perte de précision, de distances optiques arbitrairement longues. Une application d'un mode de réalisation préféré du procédé présenté est la détermination précise de l'indice de réfraction d'un échantillon à une longueur d'onde donnée, échantillon dont l'épaisseur physique est connue. Une autre application dudit mode préféré est la détermination précise de l'épaisseur physique d'un échantillon dont l'indice de réfraction est connu. Une autre application dudit mode de réalisation est la détermination précise du rapport des indices de réfraction à deux longueurs d'onde données.

Abstract: A frame over which woven wire mesh is to be stretched and secured to form a sieving screen and which can be used to screen solids from drilling mud recovered from down-hole when drilling for oil or gas. The frame is a rectilinear moulded plastics frame having edge regions by which it is secured in place in a shaker. Within the frame is a plurality of rectilinear windows formed by an orthogonal array of intersecting ribs also of moulded plastics material. Some of the ribs are internally reinforced by rigid metal members which extend orthogonally between hollow box-section members which define a sub-frame for reinforcing the four edge regions of the frame. The ends of the sub-frame members are joined at the four corners of the sub-frame. In this way not are only the edge regions of the frame reinforced internally but so also are some of the orthogonally intersecting ribs, so as thereby to produce a rigid frame for the screen. The internal reinforcement for those ribs which are to be reinforced may comprise hollow box-section metal members which may be of similar cross section to that of the sub-frame members, or the internal reinforcement for those ribs which are to be reinforced comprises metal I-beam cross section members, which typically have the same height as the height of the box-section members forming the sub frame.
