Abstract: A method of evaluating a subterranean formation includes conveying a tool along a borehole. The tool includes a transmitter that transmits a drive pulse and a receiver that receives at least one formation response to the drive pulse. The method further includes calculating a signal-to-noise ratio of the at least one formation response and comparing the signal-to-noise ratio to a programmable threshold. The method further includes determining, based on the comparing, an adjusted drive pulse to transmit and transmitting the adjusted drive pulse. The method further includes and receiving at least one formation response to the adjusted drive pulse and deriving formation data from the at least one formation response to the adjusted drive pulse.

Abstract: A method for execution by an auditing unit includes sending a verification request to a storage unit that includes a slice name and a challenge value. A proof of knowledge is received from the storage unit in response, where the proof of knowledge is generated by the storage unit based on a prover output value generated by performing a combined integrity function on the challenge value and slice data associated with the slice name. A verifier output value is generated by the auditing unit as a function of the challenge value and a known slice integrity check value for the slice name. Output verification data is generated by comparing the prover output value to the verifier output value. A corrective action is initiated on the storage unit when the prover output value compares unfavorably to the verifier output value, or when the proof of knowledge is evaluated to be invalid.

Abstract: A pulpless core is provided with flexibility for superabsorbent expansion by using elastic strands stretched and coupled to a nonwoven layer, and then relaxed partially to create receiving valleys (puckers) and the puckers are provided with superabsorbent polymer, and then a layer of nonwoven or acquisition film can be coupled on top of nonwoven/elastic/sap carrier layers to create an absorbent core laminate. A tubular core can be created and placed into a product with or without additional absorbent material between adjacent tubular members. A printed back sheet corresponding to either the tubular core shape, or void spaces between tubular members can be provide. A forming drum pocket can be profiled to match tube or tube shaped zones and elastic placements between adjacent tubes, if desired.

Abstract: A method of processing a non-virgin sulfuric acid solution for the preparation of aluminum sulfate comprises the steps of combining a sulfuric acid solution having less than 90% sulfuric acid with water to form a mixed solution of no less than about 10% sulfuric acid. An alumina-containing compound such as aluminum hydroxide or aluminum bauxite is then added, the combination forming a pH of 2.0 or less. Once a specific gravity of less than about 1.36 is reached, the aluminum sulfate cools and settles overnight before filtering and/or storing.
