Electrical methods and systems for concrete testing
Hundreds of thousands of concrete bridges and hundreds of billions of tons of concrete require characterization with time for corrosion. Accordingly, protocols for rapid testing and improved field characterization systems that automatically triangulate electrical resistivity and half-cell corrosion potential measurements would be beneficial allowing discrete/periodic mapping of a structure to be performed as well as addressing testing for asphalt covered concrete. Further, it is the low frequency impedance of rebar in concrete that correlates to corrosion state but these are normally time consuming vulnerable to noise. Hence, it would be beneficial to provide a means of making low frequency electrical resistivity measurements rapidly. Further, prior art techniques for electrical rebar measurements require electrical connection be made to the rebar which increases measurement complexity/disruption/repair/cost even when no corrosion is identified. Beneficially a method of determining the state of a rebar without electrical contact is taught. |

Sound attenuator apparatus and method
Sound waves of an amplitude having a waveform (first value as a function of time and a first maximum) pass into a manifold, which subdivides flow and sound into multiple paths of differing length, yielding transit times offsetting the arrival of each instance of the waveform at an outlet or exit. This minimizes the addition of energy (sound volume, amplitude) arriving at the exit or terminus from each path. Amplitude is thereby reduced (although the waveform shape remains), repeated and offset by the transit time delays of paths discharging at the terminus. One may select the number of paths based on a desired reduction in the sound amplitude. That number is approximately inversely proportional to the ratio of the reduction. For example, six unique paths in an experiment reduced original amplitude (sound volume) to a sixth at an exit. |

Such microbial strains are suitable for human therapy. The disclosure further provides compositions (e.g., pharmaceutical compositions) methods of using the microorganisms and compositions, e.g., for the treatment of type 1 diabetes (T1D), including those with residual beta-cell function, e.g., recent-onset T1D. The microorganism may be administered orally, delivers the microorganism into the gastrointestinal tract, where it is released and expresses the bioactive polypeptides, The methods of the present disclosure are particularly well suited for subjects possessing residual beta-cell function, e.g., for subjects with recent-onset T1D. |

Three-dimensional culture of primary cancer cells using tumor tissue
A method of producing a cell mass by three-dimensional culture of primary cancer cells having proliferative ability and properties of handleability, versatility, and high-throughput performance, in which a tumor tissue is used as a starting material, proliferation of cells such as fibroblasts other than cancer cells is inhibited, and the cell mass includes primary cancer cells as a main component. The object is achieved by providing a method of producing a cell mass by three-dimensional culture of primary cancer cells using a tumor tissue, including: a three-dimensional culture step of culturing cells obtained from the tumor tissue in a medium containing a 5% v/v or less extracellular matrix on a substantially low-adhesive cell culture substrate. |

Measurement apparatus
A measurement apparatus according to an embodiment of the present technology includes a light source, a filling portion, and a detector. The light source emits illumination light. The filling portion includes a first surface portion and a second surface portion which are provided on an optical path of the illumination light and are opposite to each other, the filling portion enabling a cavity between the first and second surface portions to be filled with liquid including a cell. The detector detects an interference fringe of the illumination light passing through the cavity, the interference fringe being caused by the liquid including the cell. |
