Abstract: The present invention relates to a method of solidifying radioactive waste containing boron, The method includes (a) mixing the radioactive waste, metakaolin, fumed silica, potassium hydroxide, and water to generate a second mixture, in which the radioactive waste contains boron.

Abstract: An apparatus for providing tire information is provided. The apparatus includes a detector that detects driving information as a vehicle is being driven and a controller that calculates a relative speed of a tire of the vehicle and a resonance frequency of the tire based on the driving information. The controller then compares the calculated relative speed and the calculated resonance frequency with a previously learned determination reference value to determine whether the tire is deflated.
