The gas pipelines need to be inspected in the case of existence of pipeline's inner problems. Usually, inspection for leakage of gas pipeline has been carried out by wired probes or wired robots equipped with a CCD camera. However, the above inspection approaches are restricted by the cable in the pipe. This study thus focuses on an inspection approach based on microwave communication. However, obtaining...
The Gray-Buster-Advance Lining (GBA) method for the renovation of gray cast-iron pipes has been developed. In general, gray cast-iron pipes installed in the past are prone to be broken by ground subsidence. The breakage of these pipes must be prevented in order to reduce the risk of gas leak accidents. This GBA method can form a thick synthetic resin membrane inside the pipes without the need for...
To reconsider the problems arising from the use of the phase plate as a test plate inserted into a polarized light microscope system for the analysis of triclinic calcium pyrophosphate dihydrate (t-CPPD) crystals, or Ca 2 P 2 O 7 ·2H 2 O in the synovial fluid of arthritis patients, we made the polarized light microscopy observations using a phase plate with a retardation...
