Abstract: Sonde oligonucléotidique comprenant un ligand fluorescent et une molécule extinctrice de fluorescence capable d'éteindre la fluorescence du ligand. La sonde oligonucléotidique peut se présenter au moins dans une configuration monocaténaire en l'absence d'hybridation, lorsque l'extincteur de fluorescence est suffisamment proche du ligand pour en éteindre la fluorescence. Elle peut également se présenter au moins dans une configuration hybridée avec un polynucléotide cible lorsque l'extincteur de fluorescence n'est pas suffisamment proche du ligand pour en éteindre la fluorescence. L'utilisation de ces configurations hybridée et non hybridée fait que le ligand et l'extincteur de fluorescence sur la sonde présentent différentes intensités de signal de fluorescence selon que la sonde est hybridée ou non. En conséquence, il est possible de déterminer si la sonde est hybridée ou non d'après les changements de l'intensité de fluorescence du ligand, de l'extincteur de fluorescence ou d'une combinaison des deux. Par ailleurs, étant donné que la sonde peut être conçue de telle sorte qu'un extincteur de fluorescence éteigne la fluorescence du ligand lorsque la sonde n'est pas hybridée, il est possible de déterminer d'emblée que le ligand aura une fluorescence limitée jusqu'à ce que la sonde soit hybridée ou digérée.

Abstract: The present invention concerns the feasibility to economically exploit ores that contain gold and platinum metals, in which the recovery of platinum metals by the conventional processes is not feasible to be employed for ores that do not present occurrences of platinum metals and mineralogically associated sulfites.        The process to extract gold, silver and platinum metals from ores, concentrates and tailings according to the present invention is achieved through cyanidation under pressure, in which the material undergoes cyanidation in an autoclave with an alkaline solution (pH between 9 and 12.5), containing concentrations of cyanide between 50 and 15,000 mg/l.      The temperature and the pressure are controlled within the range of 40 to 300°C and 0.5 to 20 atm, respectively. Prior to the cyanidation under pressure, a cyanidation stage at room temperature can be conducted either followed or not by the adsorption of the extracted gold. After pressure cyanidation, the gold is recovered from the solution by adsorption/desorption, elutriation and electrolysis or cementation and the platinum metals by precipitation or by adsorption on the resin of the expended electrolyte.

Title: Method and apparatus for a unique word differential detection and demodulation using the unique word differential detection
Inventor: IWASAKI MOTOYA
IPC: H04J3/06
Filed: 1997-11-26
Granted: 2002-02-19
Abstract: A unique word differential detection system of the present invention is intended to provide a system that can expand a measurement range for the carrier frequency offset of the quasi-synchronized detection signal while maintaining detection of unique word position at a high accuracy, and maintaining a resolution for the carrier frequency at a low level. To this end, in an initial acquisition mode, it uses a first UW differential detection circuit with the number of delay symbols N (0.5 , N ~ 1) and a second differential detection circuit with the number of delay symbols N/2 to generate a first UW detection signal of a first quasi-synchronized detection signal and first frequency offset information.  The first frequency offset information reduces frequency offset of a second quasi-synchronized detection signal for demodulating a data signal.  Then, the mode turns to a fine tune acquisition mode, where a third UW differential detection circuit with the number of delay symbols M (1 , M) operates, and generates a second UW detection signal and a second UW detection signal for double check when it detects a UW from a third quasi-synchronized detection signal.

Abstract: A meteorological radar system that can continuously and detailedly observe an object. The search radar section continuously searches for an atmospheric phenomenon as a target within a wide search range while the search radar control section rotatably scans the search radar antenna. The scanning range deciding section decides the scanning range of an observation radar section from the location of an atmospheric phenomenon detected by the atmospheric phenomena detecting section with the data obtained by the search radar section and thus sets the observation radar control section in the observation radar section to the scanning range. The observation radar antenna can continuously observe a narrow scanning area corresponding to an object with narrowed beams while the search radar section continues its searching operation, so that an object can be measured with high space and time resolution.

Title: A system and method for routing messages in radiocommunication systems
Inventor: BODIN ROLAND STIG
IPC: H04L29/06
Filed: 1998-01-09
Granted: 2007-11-20
Abstract: A method and system for improving the routing of messages in a, radiocommunication system are disclosed. In an exemplary system, messages which originate at a mobile unit are routed through both a service center associated with the originating mobile and a service center associated with a recipient mobile. If the recipient has subscribed to an enhanced message routing service, then the home location register returns an address of the recipient's service center in response to a request for routing information. When the home location register is queried again for routing information for the same message, the enhanced message service indicator is suppressed so that the home location register returns a routing number for the equipment which is currently supporting radiocommunication with the recipient, rather than returning the service center address a second time.
