Abstract: The present invention provides radioactive glass microspheres for embolization and a preparation method and an application thereof. A nuclide oxide and a foaming agent are added into a glass matrix, blended and uniformly mixed for making the foaming agent decomposed and vaporized at a high temperature to generate bubbles, so as to prepare the radioactive glass microspheres for embolization with cavities. The radioactive glass microspheres for embolization have a density of 1.4-2.3 g/cm3, a nuclide loading rate of 15-40 wt % and a higher and more stable radiation dose, can achieve better distribution and deposition effects in liver blood vessels after injection, and can achieve a better therapeutic effect for hepatocellular carcinoma (HCC).

Abstract: Systems, methods and apparatus for connection of a multi-stage turbocharger to a heat exchanger are disclosed. The multi-stage turbocharger includes at least first and second compressors with respective first and second outlets. An air intake system is provided that connects each of the first and second compressor outlets to a common inlet of a heat exchanger. The air intake system includes a flow transition segment connected to the first and second compressor outlets, a diffuser segment, and a flow delivery segment connected to the inlet of the heat exchanger.

Abstract: A waste gate assembly includes a waste gate conduit configured to receive exhaust gas. The waste gate conduit includes a first portion having a first inner diameter and a second portion having a second inner diameter and fluidly coupled to the upstream portion. The first inner diameter is less than the second inner diameter. Additionally, the waste gate assembly includes a waste gate valve operably coupled to the waste gate conduit and configured to move between an open position to permit a flow of the exhaust gas and a closed position to inhibit the flow of the exhaust gas.
