Abstract: Procédé et système de réseau de mise à jour de base de données en direct à l'aide de la programmation orientée objet pour élaborer un programme de blocs séparés, chacun étant accessible, modifiable et remplaçable séparément. Le système comporte un terminal utilisateur (12), un terminal principal (13) et un canal de communications (20). Les dates d'origine des blocs modulaires utilisateur d'informations mémorisées dans le terminal utilisateur (12) sont comparées, sur le canal de communications (20), avec les dates d'origine des blocs modulaires principaux correspondants d'informations stockées dans le terminal principal (13). Les blocs modulaires principaux dont les dates d'origine sont plus récentes que les blocs modulaires utilisateur correspondants sont envoyés au terminal utilisateur (12) sous forme de blocs mis à jour sur le canal de communications (20). Les blocs mis à jour transférés sont ensuite utilisés pour mettre à jour les blocs modulaires utilisateur d'informations pertinents. D'autres terminaux principaux (14) sont également accessibles au terminal utilisateur (12) et les autres blocs d'informations mis à jour peuvent être transférés au terminal utilisateur (12).

Abstract: L'invention porte sur la production d'anticorps spécifiques contre la région d'extrémité carboxylique de la synthétase du monoxyde d'azote humaine inductible (hiNOS). On utilise ces anticorps monospécifiques dans des systèmes de dosage pour déceler la présence d'hiNOS. L'élévation de la teneur en hiNOS survient dans le cas de l'hépatite et des affections intestinales inflammatoires ainsi que dans celui de nombreuses maladies inflammatoires. On utilise les anticorps monospécifiques et les systèmes de dosage pour quantifier l'hiNOS en tant qu'indicateur d'une activité d'hiNOS ainsi que pour évaluer des effecteurs potentiels d'hiNOS.

Title: Regulatory elements conferring tapetum specificity
Inventor: HUFFMAN GARY A
IPC: C12N15/29
Filed: 1996-06-07
Abstract: A 94 base pair DNA regulatory element that confers anther tapetum-specific gene expression has been discovered, isolated, and characterized. Additional tapetum-specific regulatory elements have been developed by mutating the 94 base pair anther box. These tapetum-specific regulatory elements can be used to control the expression of a foreign gene that disrupts the function of tapetal cells. Similarly, the combination of at least one tapetum-specific regulatory element and at least one anther-specific regulatory element can be used to disrupt pollen production in anthers. Thus, the control of maize pollen production can be achieved by using a tapetum-specific regulatory element to produce male-sterile plants. Various methods can be used to restore male fertility in the F1 generation of such male-sterile plants.

Patent CA-2229026-A1 (CA)
Title: Cryptographic access and labeling system
Inventor: FOLLENDORE ROY D III
IPC: H04L9/10
Filed: 1996-06-03
Abstract: An access control module permits a user with a preassigned passphrase to have access to the encryption or decryption portion of a program by comparing a generated vector or key with a partially decrypted version of a second vector or key stored on a portable storage medium, such as a floppy disk. If successful, the access control module creates a main key that is then used throughout the remainder of the program to encrypt or decrypt labels. Part of the encryption or decryption process utilizes an internal, reproducible, but not reversible, scrambling subroutine in which the bytes of an initializing vector are successively Exclusive Ored with one another; an input number, called spinup number, controls the number of times the process is repeated.

Title: Method and device for purifying exhaust gas of engine
Inventor: IGARASHI KOUHEI
IPC: F01N13/02
Filed: 1996-11-13
Abstract: An engine (1) has first and second cylinder groups (1a) and (1b). The first cylinder group (1a) is connected to a three way (TW) catalyst (8a). The second group (1b) and the TW catalyst (8a) are connected, via an interconnecting duct (13) to an NH3 adsorbing and oxidizing (NH3-AO) catalyst (14a). The first group (1a) performs the rich operation, and the second group (1b) performs the lean operation. In the TW catalyst (8a), NO x exhausted from the first group (1a) is converted to NH3, and the NH3 reduces the NO x exhausted from the second group (1b) in the NH3-AO catalyst (14a). A NO x occluding and reducing (NO x-OR) catalyst (11a) is arranged in the exhaust passage between the second group (1b) and the interconnecting duct (13), to thereby suppress the NO x amount flowing into the NH3-AO catalyst (14a).

Title: Gas and liquid mixing apparatus and methods
Inventor: BAILEY WAYNE A
IPC: C02F3/12
Filed: 1997-02-01
Abstract: Improved apparatus and method for mixing and introducing gas into a large body of liquid. The apparatus supports and rotates a plurality of spoke-like discharge members (484) below the surface of the liquid. The members have upwardly facing perforated discharge surfaces (485) through which compressed gas is released up into the liquid.  Preferably the members have non-porous lower portions. To counter upward 'lift pump" effect forces created by the rotating members, the members are tilted with their leading edges lower than their trailing edges. The tilt of the members and the speed of rotation are balanced so that the resultant angle of attack of the liquid relative to the discharge surfaces is zero or slightly greater, for efficiently and effectively shearing the emerging gas into relatively small size bubbles.
