BACKGROUND The high recurrence rate after surgery for colorectal cancer liver metastasis (CLM) remains a crucial problem. The aim of this trial was to evaluate the efficacy of adjuvant therapy with uracil-tegafur and leucovorin (UFT/LV). METHODS In the multicenter, open-label, phase III trial, patients undergoing curative resection of CLM were randomly(More)
This paper studies the relation between AC surface flashover voltages (FOVs) of an epoxy insulator and the surface resistivity in arc-decomposed SF<sub>6</sub> gas. It was found that as lowering the surface resistivity the FOV decreased and approached a constant value below the surface resistivity 109 ohm/square. The FOV characteristics and the discharge(More)
This paper proposes a multi-probe SPM using fringe patterns which is able to measure the large area. The composition of the chip accumulates 50,000 probes in the area of 5 mmtimes5 mm. We fabricated the multi probes, and by using the chip the fringe patterns image could be taken with the CCD camera
