Abstract: The present invention provides a novel class of detergents referred to herei n as lipopeptide detergents. Lipopeptide detergents comprise an amphipathic .alpha.-helical peptide having a hydrophobic or neutral face and a hydrophil ic face. To each end of this peptide is covalently linked an aliphatic hydrocarbon tail, these aliphatic tails being linked thereto such that they associate with the hydrophobic or neutral face of the peptide. Lipopeptide detergents can advantageously be used to stabilize membrane proteins in the absence of a phospholipid bilayer in a manner that preserves the native conformation and permits the subsequent crystallization thereof.

Abstract: The invention comprises a continuously variable transmission pulley.  The pulley comprises at least one axially movable sheave section which is coaxial with a second sheave section. Each sheave section (31, 32, 33, 34) has a series of radial grooves (29, 30) which are axially and radially aligned. The radial grooves are arranged in pairs between each sheave section. The belt blocks (26) span between the sheave sections, each having opposing arcuate ends that slidingly engaging a pair of grooves. The belt blocks are arranged circumferentially about an axial sheave centerline. Each belt block also has a surface for receiving a multi-ribbed belt (20). At least one elastic member (24, 25) encircles the belt blocks so as to control their relative positions, keeping them in contact with the sheave grooves as the pulley rotates. As the movable sheave is moved axially, each belt block moves radially within its respective grooves so as to increase or decrease the effective diameter of the pulley.

Title: Analyse homogene d'hybridation de duplex ou de triplex a l'aide de multiples mesures dans differentes conditions
Inventor: ERIKSON GLEN H
IPC: G01N27/06
Filed: 2001-01-23
Granted: 2010-05-04
Abstract: L'invention concerne des techniques d'analyse homogène destinées à l'hybridation, la détection et l'évaluation d'acides nucléiques. Cette analyse consiste à obtenir des signaux depuis un échantillon d'essai, avant et pendant l'application d'une tension audit échantillon, et à établir une corrélation entre ces signaux qui indiquent l'affinité de liaison entre la sonde et la cible. Cette analyse permet de déterminer l'ampleur de la correspondance entre la sonde et la cible, la tension pouvant être étalonnée de manière à déstabiliser de façon significative toute hybridation à l'exception d'une hybridation parfaitement complémentaire. Les signaux dont l'amplitude correspond à une affinité de liaison peuvent être une conductance électrique et/ou une intensité de fluorescence. On mesure et on compare de préférence les deux paires de signaux de manière à accroître la fiabilité de l'analyse. Cette analyse permet de détecter une hybridation spécifique entre des sondes monocaténaires et des cibles bicaténaires non dénaturées pour former des triplex, ce qui rend superflue la dénaturation des cibles. Les techniques d'analyse de l'invention peuvent également s'appliquer à des complexes d'hybridation de duplex.

Abstract: A system and method in a General Packet Radio Service (GPRS) network for interfacing a Base Station System (BSS(11)) and a Serving GPRS Support Node (SGSN(12)). A protocol stack in the BSS and the SGSN includes a User Datagram Protocol (UDP) layer over an Internet Protocol (IP) layer. Data packets are transmitted between functional entities in the SGSN and the BSS over a connectionless IP network. The protocol stack includes a Base Station System GPRS Protocol (BSSGP) protocol layer that provides radio-related, Quality-of-Service (QoS), and routing information that is required to transmit user data between the BSS and the SGSN. The stack also includes a modified Network Services (NS') layer which is divided into an upper NS'-Network Service Control (NS'-NSC) sub-layer and a lower NS'-Sub-Network Service (NS'-SNS) sub-layer. The NS'-NSC sub-layer maps to the BSSGP layer and manages functional entities therein. The NS'-SNS sub-layer maps to the UDP and IP layers and provides access to the IP network. A single UDP port is reserved to make the NS layer and the BSSGP layer act as an application over the IP stack.

Granted: 2010-02-09
Abstract: A proton conduction material having high proton conductivity and exhibiting high reactive gas permeability regardless of the percentage of water content is provided. This proton conduction material consists of a polymer material whose molecular structure has a strong acid functional group. This polymer material consists of a polymer of a mixture of a monomer having an end structure expressed by a formula (1) or a vinyl radical and a monomer expressed by a formula (2). (see formula 1) (see formula 2) A strong acid functional group is included in the structure of both the monomers. It is to be noted herein that R1, R2, R3, R4, R5 and R6 represent a hydrocarbon radical, a fluoro-substituted hydrocarbon radical, or a trimethylsiloxy radical. Because introduction of a structure in which a hydrocarbon radical is bonded to silicon weakens interaction and causes bulkiness, gaps are created among atoms. If the number of the gaps among the atoms increases, the diffusion coefficient of reactive gases increases. As a result, permeability of the reactive gases can be enhanced.
