A moving inspection device inspecting an inspection target while realizing the simplification of the configuration and significant size reduction/weight reduction of the device, a moving inspection method, and a method for manufacturing a steel material. The device includes a moving inspection device body configured to inspect an inspection target for defects while moving over its surface. The moving inspection device body includes: a carriage that moves by at least two wheels that rotate forward and backward over the surface; and at least one inspection sensor on the front end side or the rear end side of the carriage. An inspection region of the inspection target is divided into two divided regions across a straight line, and the carriage is configured to move when the inspection sensor is directed to side edges sides of the divided regions facing the straight line in each of the two divided regions.

A scale composition determination device (10) determines that Fe.sub.2O.sub.3 has been generated in the outermost layer of a scale (SC) in the case where at least one of spectral emissivities at one wavelength and the other wavelength that are measured by radiometers for spectral emissivity measurement (21a, 21b) is not within a predetermined range including spectral emissivities of FeO at one wavelength and the other wavelength, and determines that Fe.sub.2O.sub.3 has not been generated in the outermost layer of the scale (SC) in the case where all of the spectral emissivities at one wavelength and the other wavelength that are measured by the radiometers for spectral emissivity measurement (21a, 21b) is within the predetermined range including the spectral emissivities of FeO at one wavelength and the other wavelength.

A method of determining one or more target nucleic acids in cells includes the steps of: delivering one or more probes into the cells, each of the one or more probes being capable of binding with corresponding target nucleic acid present in the cells to form a double-stranded sequence; inserting an array of functionalized nanoneedles into the cells to bind with the double-stranded sequence; and hybridizing the bound double-stranded sequence with a first and second DNA sequence to produce a hybridized product, the first and second DNA sequence being at least partially complementary to each other. A kit for determining a target nucleic acid in cells includes a first reagent comprising a probe for binding with the target nucleic acid to form a double-stranded sequence; and an array of functionalized nanoneedles comprising a protein for binding with the double-stranded sequence.

Methods and systems for high fidelity electrical tomographic processes are provided for herein. Specifically, the use of a purpose-selected fluid configuration is described, used to fill the void space between mechanically fixed sensing electrodes and the target object to sense and reconstruct. In some embodiments, this fluid configuration enhances or masks changes in electrical measurements in response to certain materials known or suspected to exist within the sensed volume. In other embodiments, a plurality of fluid configurations may be employed to improve the quality of reconstruction, or resolve additional spatial dimensions. Exemplary applications in medicine and manufacturing are also provided.
