Granted: 2011-03-08
Abstract: A method for selecting candidate microbial antagonists that will suppress Fusarium head blight (head scab) in cereals, particularly in wheat and barley relies on the ability of strains obtained from seed heads to utilize choline or betaine as a sole carbon source. Strains that are choline or betaine utilization positive are bioassayed in the seed head of a cereal plant inoculated with F. graminearum for the ability of the strains to reduce the incidence of FHB. Strains that suppress the disease are further evaluated in greenhouse and field studies. From a pool of more than 700 strains, 4 yeasts (NRRL Y-30213, NRRL Y-30214, NRRL Y-30215, and NRRL Y-30216 and 1 bacteria (NRRL B-30212) have been identified as being superior antagonists capable of suppressing head blight.

Abstract: L'invention concerne un dispositif électrothermique de dégivrage par zones conçu pour un avion, employant une bande thermoconductrice fixée sur le bord d'attaque d'une structure d'avion se heurtant à des courants d'air durant le vol. La bande thermoconductrice comporte un tringle de séparation dans le sens de l'envergure, ainsi qu'une première et une deuxième zone d'accumulation et d'élimination de la glace (132, 134). Cette bande comporte également une couche non-métallique thermoconductrice et électroconductrice composée de feuilles de graphite expansées flexibles, stratifiées sur une couche thermoconductrice extérieure, dans laquelle la largeur de la couche de feuilles de graphite expansées flexibles, au niveau de la zone de la tringle de séparation, est toujours supérieure à la largeur de la couche de feuilles dans chaque zone d'accumulation et d'élimination de la glace. Par conséquent, la zone de la tringle de séparation présente une résistance électrique diminuée, un flux de courant supérieur, et devient plus chaude que les zones dont la couche de feuilles est plus mince. Comme les feuilles de graphite expansées flexibles possèdent une structure monolithique pouvant être formée, sculptée ou appliquée en couches afin de former différentes largeurs dans différentes zones, un seul mécanisme de commande, destiné à un ensemble individuel de terminaux électriques, est nécessaire pour produire des différences de températures dans la tringle de séparation et les zones d'accumulation et d'élimination de la glace, pour un dispositif de dégivrage par zones cyclique.

Title: Method for determining physiological effects of hemoglobin
Inventor: STAMLER JONATHAN S
IPC: A61K31/255
Filed: 2000-08-02
Granted: 2010-05-11
Abstract: NO preferentially binds to the minor population of the hemoglobin's vacant hemes in a cooperative manner, nitrosylates hemoglobin thiols, or reacts with liberated superoxide in solution. The distribution of minor forms of hemoglobin can be tested and the results can be used to predict whether a composition of hemoglobin will scavenge, load, eliminate, or donate NO. Hemoglobin thus serves to regulate the chemistry of NO. SNO-hemoglobin transfers NO equivalents to the red blood cell anion transport protein AE1, which serves to export NO from red blood cells. Regulation of AE1 function is the basis for methods of therapy to affect levels of NO or its biological equivalent.

Abstract: A shaft support (22) for supporting a shaft end (16b, 18b) of a conveyor roller (16, 18) is pivotable about an axis extending generally along the direction of conveyance of a conveyor (10), such that the support may pivot to accommodate a change in vertical positioning of one or both ends of the roll er (16, 18). The shaft support may also be pivotable about a generally vertical axis in order to also accommodate skewed rollers mounted at an angle not perpendicular to the direction of conveyance. Because the shaft support is pivotable about the axis extending in the direction of conveyance, the shaft support simplifies the installation and removal of the motorized roller, whi le providing for a roller that does not require a spring loaded shaft or axle. The roller may thus be a low cost roller which may be easily installed and removed from the conveyor.

Abstract: A membrane exchange humidifier employs a water permeable membrane comprising a microporous polymer and hydrophilic additive. In operation, the membrane preferably has favorable water transmission properties and resists transmission of reactant gas or other components. The membrane is suitable for use even when permeable in its dry condition to the wet or dry gases in the humidifier, and/or when the wet and dry gases are of different composition. By wetting the membrane, the presence of an amount of liquid water in the wet gas can reduce gas transmission through the membrane to an acceptable level. The humidifier is useful in fuel cell systems in which a reactant gas supply stream, such as the oxidant supply stream, is humidified primarily using water vapor from a fuel cell reactant exhaust stream. The humidifier is particularly suitable for use in conjunction with solid polymer fuel cell systems. The improved mechanical and welding properties of the membrane allow for a simpler humidifier configuration.
