Abstract: The vapor barrier for flammable liquid storage tanks provides a gas impermeable layer for covering the surface of a flammable liquid stored within a conventional flammable liquid storage tank, a tanker, a vessel or the like. The vapor barrier is formed from a plurality of spherical buoyant members. Each spherical buoyant member has a heat-resistant core or shell, a heat-reactive intumescent or flame retardant layer formed on an outer surface of the heat-resistant core, and an antistatic and oil-phobic layer formed on an outer surface of the heat-reactive intumescent layer. The vapor barrier may further be used with liquid storage tanks in which separation between the liquid and vapor phases is beneficial to prevent oxidation or other undesirable reactions.

Abstract: A method is presented for preserving metadata during an undo operation at a client computer. A first section of a document is modified on a word processing application on the client computer by performing one or more user actions in the first section of the document. While modifying the first section of the document, metadata is received at the client computer for a sec-ond section of the document. The metadata is inserted into the second section of the document. After the metadata is inserted into the second section of the document, an undo operation is performed on the word processing application. The undo operation in-cludes the steps of removing the metadata from the second section of the document, undoing the last user action of the one or more user actions in the first section of the document and restoring the metadata for the second section of the document.

Abstract: The present invention provides materials and methods for the isolation of immune cells. In one embodiment, the present invention provides a device for the isolation and separation of antigen-specific memory B cells. Immune cells will be separated by flowing the cells along a ligand-conjugated biopolymer surface. The ligand may be distributed in a concentration gradient along the z- axis of the biopolymer surface. Cells that display receptors specific for the ligands on the biopolymer will interact with the ligands and roll along the surface in the fashion of leukocyte rolling. Additive adhesive interactions will cause differential cell separation and eventual immobilization.

Abstract: Un composite de scintillateur de neutron (NSC) est fait dun scintillateur de neutron et dun liant. Le scintillateur de neutron du composite présente la formule « Li y MgBr y+2 », où y = 2, 4 ou 6, et peut aussi comprendre du cérium comme activateur de scintillation. Le liant du composite a un indice de réfraction essentiellement identique au scintillateur de neutron. Le scintillateur de neutron et le liant sont mélangés dans un NSC solide ou demi-solide suffisamment apte à lécoulement pour le moulage en un objet formé, comme un élément détecteur de neutrons dun détecteur de rayonnement. Le NSC collecte et canalise les photons dans le matériau et dans un élément de détection photoélectrique en raccord optique avec le composite. Comme les indices de réfraction du scintillateur de neutron et du liant sont essentiellement identiques, la diffusion à lendroit des interfaces du scintillateur-liant est minimisée, ce qui permet des gains defficacité de transmission qui sapprochent aux monocristaux.
