US Classification:

536 254, 536 2541

Abstract:

A method for purifying oligonucleotides by displacement chromatography on anion-exchange media, using high affinity, low molecular weight (less than about 10000 Da) displacers, is disclosed. Several examples of high affinity, low molecular weight anionic displacers are provided, including polycyclic aromatic compounds having sulfonic acid moieties attached thereon. The efficacy of the technique for high resolution separation of oligonucleotides is demonstrated for an industrial mixture.

US Classification:

73597

Abstract:

A method for determining crook potential of wood is described. One embodiment comprises nondestructively obtaining lengthwise shrinkage rates (from a third party or by direct measurement) of wood and then determining crook potential of the wood based on the lengthwise shrinkage rates. Where the wood comprises lumber, lengthwise shrinkage rate measurements typically are made on at least one major planar surface of the lumber. The method typically comprises determining lengthwise shrinkage rates two or more measuring points separated by a predetermined distance, such as at substantially one-foot intervals along the lumber. Particular embodiments of the present invention determine lengthwise shrinkage rates using infrared radiation, microwave radiation, electricity, ultrasound energy, and combinations thereof Working embodiments of the method use ultrasound energy to determine lengthwise shrinkage rates. For example, one working embodiment measures the speed of an ultrasound pulse through wood to determine the modulus of elasticity (MOE) of the wood which can then be correlated to the lengthwise shrinkage rate. In another example, lengthwise shrinkage rate can be determined from the speed of an ultrasound pulse using an empirically derived formula, such as an exponential formula.

Abstract:

A method for determining twist potential of wood is described. One embodiment of the method comprises nondestructively obtaining a grain angle of wood, such as trees or lumber, and then determining twist potential of the wood based on the grain angle. Where the wood comprises lumber, grain angle determinations typically are made on at least one major surface of the lumber. The method typically comprises determining grain angle at at least two measuring locations separated by a predetermined distance, such as at substantially one-foot intervals along the board. The method also can further comprise obtaining at least one fiber dive angle. Particular embodiments of the present invention determine grain angle using infrared radiation, microwave radiation, light energy (such as by using a laser), electricity, ultrasound energy, and combinations thereof. Working embodiments of the method used light energy and ultrasound energy to determine grain angle. For example, a first transmission speed of an ultrasound pulse through the board was determined along a first path and along a second path.

Abstract:

A method for determining warp potential of wood. One embodiment comprises nondestructively obtaining lengthwise shrinkage rates and grain angles of wood--such as trees, logs, or lumber--then determining warp potential of the wood based on the lengthwise shrinkage rates and grain angles. The method typically comprises measuring plural lengthwise shrinkage rates and plural grain angles to determine warp potential. Where the wood comprises lumber, lengthwise shrinkage rate and grain angle measurements typically are made on at least one major planar surface of the lumber at at least two measuring points separated by a predetermined distance, such as at substantially one-foot intervals along the lumber. Particular embodiments of the present invention determine lengthwise shrinkage rates using electromagnetic energy, acoustic energy, and combinations thereof. Working embodiments of the method use ultrasound energy to determine lengthwise shrinkage rates and grain angles.

Abstract:

A lighting device includes a primary housing having a light source and a secondary housing having a light source. The primary housing and the secondary housing can be magnetically and releasably coupled to each other by at least one magnet on either or both housings. The primary housing can include an upper shell and a lower shell pivotally coupled to each other to form a clamshell configuration. A hands-free emergency lighting method can include decoupling the primary housing from the secondary housing and magnetically coupling the secondary housing to a metal surface, such as a vehicle, to indicate an emergency while the primary housing can be opened and used to illuminate an area.
