    Abstract: A structural, load-bearing panel useful in constructing multistory buildings may have a panel height, panel width, and panel thickness, and may include a first layer comprising at least 75 wt. % of concrete, relative to a total weight of the first layer; an insulation layer comprising flexible polymer, the insulation layer having a thickness of at least 5 cm; and a second layer comprising at least 75 wt. % concrete, wherein the insulation layer is sandwiched between the first and second layers, and wherein the panel is suitable to be set in any of a planar, curved, and polyhedral cross-sectional shape. Set panels are not flexible, though the flexibility of the insulation layer, particularly of a polyethylene foam, may allow the panel to have a curved, or polyhedral cross-section while still serving as a structural support.

    Abstract: An apparatus for measuring the rate of Cu2S formation in power transformers comprising a sealable transformer vessel and a sealable lid with at least four sealable ports, and an internal apparatus configuration involving a copper metal sheet, a power transformer, a temperature sensor, and a weighing device providing real-time feedback data, whereby these components are submerged in an effective amount of a reactive sulfur-containing transformer oil and sealed. An inert gas atmosphere is provided within the transformer vessel by a gas bubbler. The transformer oil is heated with a heating bath to a reactive temperature for Cu2S production. A method of measuring the rate of Cu2S formation whereby the apparatus is purged with an inert gas, heated to a reactive temperature, examined for Cu2S formation, the Cu2S produced is quantified and the rate of formation of Cu2S is calculated.

    Abstract: A multiphase flow calibration semi-closed loop system includes an oil-gas-water separation unit, a multiphase flow calibration unit, a single phase flow calibration section, a gas flow section, a flow data acquisition unit, and a programmable logic controller (PLC). The system is designed to have a two-step calibration process. In a first step, single phase water flow meters and single phase oil flow meters of the system are calibrated independently. In a second step, multiphase flow meters or multiphase water cut meters are calibrated using the pre-calibrated water flow meter, pre-calibrated oil flow meter, and the pre-calibrated gas flow meter. In doing so, the oil-gas-water separation unit, the multiphase flow calibration unit, the single phase flow calibration section, and the gas flow section communicate with the flow data acquisition unit providing real time data. Thus, the PLC connected to the flow data acquisition unit can perform the required calibration processes.
