摘要： A device, and corresponding method, for determining a presence of lead in a material composition of a pipe includes a probe, a resonant frequency measurement circuit, and a material analyzer. The probe includes an oscillator circuit and can be inserted into an interior cavity of the pipe and emit electromagnetic radiation. The frequency measurement circuit operatively communicates with the oscillator circuit and outputs resonant electromagnetic frequency measurement data indicating a resonant electromagnetic frequency of the oscillator circuit. The material analyzer receives the resonant electromagnetic frequency measurement data, and an additional measurement selected from the group consisting of (i) a measurement of power dissipation of the oscillator circuit and (ii) an interior diameter of the pipe, and outputs a positive or negative indication of whether lead is present in the material composition based on the resonant electromagnetic frequency measurement data and the additional measurement.

摘要： A fluid state detection sensor accurately detects a fluid state by suppressing the deterioration of a conductivity measurement accuracy due to its characteristics. The sensor includes an electrode section configured by a pair of electrodes arranged opposite each other, a conductivity acquisition unit detecting a resistance value from an inter-electrode voltage value acquired through the electrode section and acquiring a fluid conductivity, a controller executing entire sensor's processing according to a control program stored in ROM etc., a memory storing correction values for fluid whose conductivity is greater than a predetermined value calculated by a conductivity calculator, which calculates the fluid conductivity from the inter-electrode voltage value, a corrector correcting the conductivity calculator calculated conductivity using the correction value stored in the memory when the fluid whose conductivity calculator calculated conductivity is greater than the predetermined value, and an output section outputting corrected conductivity.

摘要： A method for fabricating a composite film structure, the method includes determining a desired morphology for a metallic layer of the composite film structure, selecting a first metal substrate based on the determining, transferring a graphene layer onto the first metal substrate, depositing the metallic layer on the graphene layer to achieve the desired morphology, and removing the first metal substrate from the graphene and the deposited metallic layer to form the composite film structure. A surface energy difference between the first metal substrate and the deposited metallic layer results in the desired morphology of the metallic layer.

摘要： A precast dam structure includes at least two precast segments coupled together via linkages and a flow path structure. The flow path structure defines a flow path having an intake port and a draft port and is associated with at least one of the at least two precast segments. The flow path structure is configured to provide a change in flow direction, either internally or externally, from the at least one of the at least two precast segments.
