Abstract: Solder pastes having vehicles including blends of low boiling point alcohols and relatively high boiling point alcohols are described which leave residues which may be cleaned using only water are described. The low boiling point alcohols have a boiling point range of between about 65 DEG  and about 150 DEG  C. whereas the high boiling point alcohols have a boiling point in rhe range of about 150 DEG  to about 270 DEG  C. The solder pastes also use water-soluble organic acids as fluxing agents such as compounds of the formula: <IMAGE>  where R is an electron withdrawing group such as fluorine, chlorine, bromine, iodine, sulfur, hydroxyl, nitrile, and benzyl. Other suitable formic-acid fluxing agents include, but are not limited to, adipic acid, polyacrylic acid, methacrylic acid and polymethacrylic acid. The compounds clean oxides from the printed circuit boards (PCBs) under assembly and then volatilze leaving a residue to be cleaned away. The cleaning step involves rinsing with water. No undesired residue remains indicating that the organic acids of the invention are effective in cleaning boards. Malic acid is a preferred organic acid fluxing agent.

Date Sep. 17, 1992.The method of electrophoresis uses for separation of charged species their different mobilities in an electric field. The process is usually carried out by forcing the molecules to migrate through an aqueous gel. The gels are run in essentially two types of electrophoretic units: vertical and horizontal ones. It was found that in the standard submerged electrophoresis units the resolution of DNA in the poly(NAT) gels was never so good as in the vertical system. It was observed that by looking at the gel from above under an angle declined from the vertical, the viewed DNA bands in the gel were much sharper than they were pictured on the photograph taken by a camera positioned more or less vertically above the gel. On basis of this observation it was assumed that the diffuseness of bands seen on the photograph did not originate from a real diffuseness of bands in the gel, but rather from the vertical position of the camera and bending of the bands against the vertical axis. If the bands in the gel could be made essentially vertical, then the resolution taken by the usually positioned camera would be qualitatively better and besides that independent of the sample volume. It is the main goal to prevent such bending of bands in gels during electrophoresis.

Abstract: A method is disclosed for preparing a transplantable tissue which has been cryopreserved with an intracellular cryoprotectant and then thawed. After thawing, the tissue is treated with a diluent (or eluent) solution to reduce the level of cryoprotectant in the cells to a substantially non-toxic level. This is conducted using a single dilution step. Cryoprotectants which are removable in this manner include dimethylsulfoxide, glycerol, propanediol and other compounds which penetrate the cells. The dilution step does not require end point titration and can be conducted over a time period greater than about 5 minutes.

Le récepteur de navigation à localisation couplée mesure périodiquement la phase de la porteuse, la fréquence de la porteuse, la phase de modulation et l'amplitude de la porteuse pour tous les signaux arrivant aux entrées de réception du récepteur et estime périodiquement les valeurs actuelles de la phase et de la fréquence de la porteuse, et la phase de modulation associées à tous les signaux reçus, le processus d'estimation employant pour chaque estimation paramétrique les mesures paramétriques associées à plusieurs signaux reçus qui sont combinées correctement selon un mode statistique approprié en prenant en compte la géométrie relative des liaisons en visibilité directe, la dynamique du temps d'horloge du récepteur et les contraintes de la dynamique et du déplacement de la plate-forme du récepteur, ce système permettant de réaliser une meilleure performance dans des mauvaises conditions de réception des signaux et d'obtenir des estimations plus précises de la phase et de la fréquence de la porteuse, et de la phase de modulation pour chaque signal reçu que ce que l'on peut obtenir si l'on n'utilise que des mesures indépendantes. Par conséquent ces estimations plus précises des paramètres de base des signaux permettent d'obtenir des estimations plus précises de la position et de l'orientation de la plate-forme ainsi que les vitesses de modification de ces valeurs.
