Abstract:
A method of verifying the performance of a size standard, formed of a plurality of size standard elements, used in a nucleic acid analysis method is provided. The verification is achieved by introducing the size standard to an analysis stage and performing a size based separation on the size standard. The size based separation defines an experimental position for each size standard element. A comparison is made as to whether or not the experimental position for the size standard element corresponds with expected position. The comparison allows a decision to be made on whether or not to use the size standard, which is dependent upon whether or not the experimental position of the size standard element corresponds with the expected position.

Abstract:
Synthesis of platinum(II) di(2-pyrazolyl)benzene chloride and analogs includes forming a 1,3-di-substituted benzene including two aromatic five-membered heterocycles, and reacting the 1,3-di-substituted benzene with an acidic platinum-containing solution to form a luminescent platinum(II) complex. The luminescent platinum(II) complex is capable of emitting blue and white light and can be used as an emitter in a light emitting device.
Abstract:
The present invention provides for microbial compositions and methods for reducing the concentration of short-chain fatty acids in the gut as a way to reduce energy uptake and manage obesity. More specifically, the invention provides for decreasing short-chain fatty acids available for absorption in the human gut, such as acetate, using one or more of: a probiotic including a homo-acetogenic, acetate oxidizing bacterium that converts acetate to H2; a probiotic including an acetoclastic methanogen; a microbial electrolysis cell comprising a homo-acetogenic bacterium and/or an acetoclastic methanogen; a prebiotic that enhances the growth or function of acetate-scavenging microbiota; or a highly selective antibiotic that targets H2-oxidizing methanogens.
Abstract:
An electroosmotic (EO) pump is provided that includes a housing having a pump cavity, a porous core medium and electrodes. The porous core medium is positioned within the pump cavity to form an exterior reservoir that extends at least partially about an exterior surface of the porous core medium. The porous core medium has an open inner chamber provided therein. The inner chamber represents an interior reservoir. The electrodes are positioned in the inner chamber and are positioned proximate the exterior surface. The electrodes induce flow of a fluid through the porous core medium between the interior and exterior reservoirs, wherein a gas is generated when the electrodes induce flow of the fluid. The housing has a fluid inlet to convey the fluid to one of the interior reservoir and the exterior reservoir. The housing has a fluid outlet to discharge the fluid from another of the interior reservoir and the exterior reservoir. The housing has a gas removal device to remove the gas from the pump cavity.
Abstract:
Provided in one embodiment is an electrochemical cell, comprising: (i) a plurality of electrodes, comprising a fuel electrode that comprises aluminum and an air electrode that absorbs gaseous oxygen, the electrodes being operable in a discharge mode wherein the aluminum is oxidized at the fuel electrode and oxygen is reduced at the air electrode, and (ii) an ionically conductive medium, comprising an organic solvent; wherein during non-use of the cell, the organic solvent promotes formation of a protective interface between the aluminum of the fuel electrode and the ionically conductive medium, and wherein at an onset of the discharge mode, at least some of the protective interface is removed from the aluminum to thereafter permit oxidation of the aluminum during the discharge mode.

Abstract:
A system and method for securing access to sensitive content on the web is disclosed. The approach automates compartmentalization practices for accessing different kinds of content with different browser instances. The automation is transparent to the user and does not require any modification of how non-sensitive content is accessed. For sensitive content, a Fresh Browser Instance (FBI) is automatically created to access the content. In addition, the automatic FBI system may provide support for novice users with predefined sensitive content sites as well as for more experienced users who can define conflict of interest (COI) classes which allows content from sites in the same user-defined class to coexist in a browser instance.
