Abstract: Described herein is an apparatus and methods for characterizing a fluid composition including exposing electrolyte to one fluid mixture, collecting a signal from an electrode in contact with the electrolyte, and simultaneously exposing the electrolyte to a second fluid, collecting a signal from a second electrode in contact with the electrolyte exposed to the second fluid, and comparing the signal difference between the electrodes with the Nerst equation wherein the temperature of the electrolyte is above 488° C. Carbon dioxide, nitrogen, and/or oxygen may be present in the fluid and/or the second fluid.

Abstract: Consolidated porous media samples and methods for their manufacture are described herein. An assembly has an outer tube having a first softening temperature and a sintered glass construct formed from plurality of beads of multiple sizes. The sintered glass construct defines pores and at least one fracture or channel. The assembly is formed by suspending at least one sheet or wire of dissolvable material in the outer tube, packing beads of different sizes around the sheet or wire, sintering the beads with the sheet or wire located therein at a temperature below the softening temperature of the tube, and dissolving the sheet or wire to generate a sintered construct defining at least one fracture or channel.

Abstract: Example methods and apparatus to measure market statistics are disclosed. A disclosed example method includes identifying, by executing an instruction with a processor, a household including self reported data stored in a data source, retrieving, by executing an instruction with the processor, an Internet protocol (IP) address from the household, identifying, by executing an instruction with the processor, a hostname label based on a reverse resolve of the IP address, determining whether the hostname label matches the self reported data, with the processor, and when the hostname label matches the self reported data, correcting, by executing an instruction with the processor, an error metric of the data source by adjusting a weight value associated with the self reported data.

Abstract: Systems, apparatuses, and methods are provided for customizing collections of products. A first user selects a subset of products for customization, and subsequently causes those products to be customized. The first user may place limitations on further customization of the subset of products. A second user associated with the customized products further customizes those products. The further customization may be restricted by the limitations imposed by the first user.

Abstract: Methods and apparatus are provided for the measurement of the compressibility of reservoir fluid. A piezoelectric material is coupled to a wall of a fluid chamber. Compressibility is derived from measured pressure changes to the fluid resulting from volumetric changes to the fluid chamber imposed by the mechanical strain of the piezoelectric material resulting from an applied electric field.

Abstract: The present invention relates to stabilization of cells at ambient temperatures. More particularly, the present invention relates to formulations, compositions, kits and methods that allow dehydration and rehydration of cells and dramatically increased recovery of functional cells after dry storage at room temperature.
