Abstract: A cDNA is prepared from mRNA. The prepared cDNA is subjected to incision with two different types of restriction enzymes. The sequence of a portion of each of the fragments obtained as a result of treatment is determined, and the fragments are classified on the basis of the determined sequence by using a primer set. At the same time, the fragments are amplified in a manner that the relative expression magnitude thereof continues to be reflected therein. When the fragments have been classified into a predetermined number of fractions, the respective fractions are subjected to electrophoresis, and a gene expression profile is produced from the results.

Title: Self-tapping screw, blank, method and dies for making the same and method for joining thin workpieces
Inventor: PRITCHARD ALAN
IPC: B21H3/02
Filed: 2002-08-09
Granted: 2010-10-26
Abstract: A headed multi-lobed blank, method of manufacturing a self-tapping screw from the blank, and resulting multi-lobed self-tapping (902) screw for joining thin workpieces (1402,1404) provides desirable thread-forming characteristics at the conical tip and body portions, and improved resistance to vibrational loosening near the head. The resulting screw, obtained from the blank and method, incorporates a threaded tapered root portion (906) between the screw head (410) and body por-tion having a cross section that varies from nearly circular in the area adjacent to the under-side of the head (410) to a maximum out-of-round (or lobular) cross section at the intersection of the tapered root portion (906) and the screw body. This shape, combined with a thread profile outer diameter that remains largely constant from the body portion through the tapered root portion (906), and a multiple coil (lead threaded) shape, ensure more secure holding of the screw (902) in a thin anchor material (1404) - with the anchor material extruded axially forward and backward (1405) around the root portion.

Abstract: Un ensemble de bagues de dilatation pour sceller un joint par rapport à un mur annulaire d'une structure rigide. L'ensemble de bagues de dilatation comprend un mécanisme d'entraînement pour mettre en prise et séparer les extrémités opposées d'une bague de dilatation afin d'agrandir radialement la bague. Le mécanisme d'entraînement inclut généralement une paire de blocs, faits en acier ou en plastique rigide, ayant par exemple, des alésages à filets opposés qui sont filetés relativement aux alésages filetés des blocs. Le boulon comprend en outre une structure de réception d'outil, telle qu'une partie d'écrou, qui peut être engagé par un outil approprié pour tourner le boulon. Les blocs sont mis en prise avec les extrémités correspondantes de la bague de dilatation. La rotation du boulon dans un premier sens éloigne simultanément les blocs l'un de l'autre le long du boulon afin d'agrandir radialement la bague de dilatation, et la rotation du boulon dans le sens opposé rapproche simultanément les blocs l'un vers l'autre le long du boulon pour comprimer la bague de dilatation.

Abstract: The invention concerns a method for separating microseismic signals from seismic signals acquired in the context of active seismic monitoring operations of underground zones being exploited. It consists in producing seismic recordings from signals emitted by a single or several seismic sources monitored by signals orthogonal relative to one another. In that case the signals are processed to separate the respective contributions of the seismic sources to the received signals and reconstruct the seismograms equivalent to those which would be obtained by separately actuating the seismic sources. The induced microseismic signals (passive seismics) are separated from the seismic signals derived from sources 5 (active seismics) essentially by isolating the contribution of the latter, by comparison with a reference spectral model to the fundamental frequencies emitted and to their respective harmonics, and by reconstructing in the time domain the induced microseismic signals and the signals derived from the seismic sources 5. The invention is applicable to seismic monitoring of underground hydrocarbon or fluid storage reservoirs.

Abstract: An alloy design approach to modify and improve existing iron based glasses.  The modification is related to increasing the stability of the glass, which results in increased crystallization temperature, and increasing the reduced crystallization temperature (Tcrystaiiization/Tmelting), which leads to a critical cooling rate for metallic glass formation. The modification to the iron alloys includes the addition of lanthanide elements, including gadolinium. The resulting properties of such a modified alloy are compared to those of an unmodified alloy in Figure 1.

Abstract: A method for the treatment and filtration of fluids, i.e. liquid effluents such as raw water containing organic pollutants in a solution, using gravity separation means (10) such as a decantation and flotation means, and membrane separation means (13) in a finishing stage, wherein a first pulverulent reagent (1) is introduced into the flow of a fluid to be treated upstream from gravity separation, and a second pulverulent reagent (2) is introduced downstream from the membrane separation. The inventive method is characterized in that the coagulant required for separation is injected before the first pulverulent reagent; in that the first and second pulverulent reagents (1,2) have different characteristics, i.e. in terms of granulometry, adsorption capacity adapted to the pollutants which are to be eliminated; and in that the second pulverulent reagent (2) is recycled from membrane separation means (13) upstream from the gravity separation means (10).

Abstract: L'invention concerne des techniques améliorées de compression vidéo consistant à comparer des blocs d'informations d'entrée vidéo selon leurs valeurs respectives de pixel à des blocs correspondants des trames immédiatement précédentes. Les blocs sont analysés afin de déterminer l'apparition d'une modification éventuelle en fonction de deux contrôles. Ceci consiste à d'abord comparer les valeurs de pixel du bloc aux valeurs de pixel du bloc précédent et si un nombre de seuil de valeurs de pixel du bloc dépasse leurs contreparties d'une quantité seuil, le bloc est estimé avoir subi une modification et est communiqué par l'intermédiaire d'un protocole de communication standard, d'une technique de compression et de média. Ceci consiste ensuite à comparer les valeurs de pixel, même si le nombre de seuil de pixels du bloc n'a pas changé, à leurs contreparties de la trame précédente afin de déterminer si l'intensité de toute valeur de pixel s'est modifiée selon une quantité supérieure à un deuxième seuil. On identifie à nouveau ce type de pixel et on estime que le bloc s'est modifié et à été communiqué.

Abstract: Various technologies for removing shoulder-bed effects from measurements of an earth formation made in a wellbore. In one implementation, a methodology for removing the shoulder-bed effects includes receiving the measurements and constructing a layered model of the earth formation. Each layer has a set of parameters corresponding to one or more types of the received measurements ascribed to each layer such that the set of parameters define a parameter space for the layered model. The methodology may further include dividing the parameter space into subspaces based on relationships among the parameters, selecting from the subspaces one or more starting points, minimizing a cost function using the one or more starting points to generate one or more candidate solutions having the shoulder- bed effects removed and selecting a final solution from the one or more candidate solutions.
