2015 IEEE 26th Symposium on Fusion Engineering (SOFE)

The heating neutral beam (HNB) systems at ITER are designed to inject a total of 33 MW of either 1 MeV D0 or 870 keV H0 beams into the ITER plasma using two injectors with a possible addition of a third injector later to increase the injected power to ∼50 MW. The injectors become radioactive due to the neutron flux from ITER and, in order to avoid the resulting complex remote maintenance, the design,...

Molecular Ecology Resources > 15 > 1 > 68 - 80

Marine planktonic copepods are an ecologically important group with high species richness and abundance. Here, we propose a new metagenetic approach for revealing the community structure of marine planktonic copepods using 454 pyrosequencing of nuclear large subunit ribosomal DNA. We determined an appropriate similarity threshold for clustering pyrosequencing data into molecular operational taxonomic...

2014 20th International Conference on Ion Implantation Technology (IIT)

The mechanism of helium-based plasma doping (He-PD) was investigated. It is found out for the first time that the mechanism is that dopant atoms are knocked-on by a huge number of helium atoms, born out by the results of experiments of helium plasma irradiation following the ultra-low energy implantations. Boron and phosphorous atoms are knocked-on to the almost same depth. Arsenic ions are also evaluated...

The HV bushing has a function of a bulk head between insulation gas (SF ₆ ) of 0.6MPa and vacuum, which is needed to insulate −1MV in vacuum in ITER heating neutral beam (NB) injection system. Mechanical analyses were carried out to verify the mechanical integrity of the HV bushing composed of five-stage double-layered insulator columns with large brazed ceramic ring and fiber reinforced plastic...

The ITER [1] fusion device is expected to demonstrate the feasibility of magnetically confined deuterium–tritium plasma as an energy source which might one day lead to practical power plants. Injection of energetic beams of neutral atoms (up to 1MeV D ⁰ or up to 870keV H ⁰ ) will be one of the primary methods used for heating the plasma, and for driving toroidal electrical current...

Pyoderma gangrenosum is a rare ulcerative disorder of the skin of unknown etiology. We present a case of pyoderma gangrenosum that occurred following total knee arthroplasty, which was initially misdiagnosed as severe wound infection. Repeated debridement procedures resulted in a large soft tissue defect around the anterior knee joint. The patient was treated successfully with a latissimus dorsi musculocutaneous...

IEEE Transactions on Plasma Science > 2011 > 39 > 6-1 > 1379 - 1385

The ITER is an international project which aims to develop an experimental reactor as a step to realize fusion energy. To inject 33 MW of 1 MeV D⁰ neutral beams for heating and current drive in ITER plasmas, D^- ions are accelerated to 1 MeV. The electrostatic accelerator consists of five acceleration stages, and each acceleration gap has to withstand 200 kV. Gaps between the accelerator and the vacuum...

Crohn's disease patients often carry gastroduodenal lesions. However, few reports have addressed specific gastroduodenoscopic findings in Crohn's disease patients.The gastroduodenoscopic findings of 63 Crohn's disease patients were examined. Those of 62 ulcerative colitis and 63 age- and gender-matched gastroesophageal reflux disease patients were also reviewed as controls. Findings of bamboo-joint-like...

The mission of the National Centralized Tokamak (NCT) is to establish high-beta steady-state plasma operation for DEMO and to contribute to ITER. Plasma performance with high-beta conditions is discussed. It is found that near break-even class plasma (QDTeq≥0.7) with high beta (β _N ≥3.5) is achievable with 25MW of NB power at I _P =4.0MA and an aspect ratio of 2.6. High beta with steady-state...

We investigated autoantibodies and their epitope(s) in Hashimoto's encephalopathy associated with Hashimoto's thyroiditis. In a proteomic analysis, they proved to recognize α-enolase. We further searched the epitope region in α-enolase using different regions of recombinant proteins expressed in cultured human cells. The amino terminal region was recognized by autobodies from a much higher proportion...

Effects of CYP2C19 gene polymorphism on cure rates for Helicobacter pylori infection by triple therapy with proton pump inhibitor (omeprazole or rabeprazole), amoxycillin and clarithromycin in Japan

M. Dojo, T. Azuma, T. Saito, M. Ohtani, more

Digestive and Liver Disease > 2001 > 33 > 8 > 671-675

Background. Omeprazole is mainly metabolized by cytochrome P450 2C19 (CYP2C19) in the liver. Pabeprazole, on the other hand, is mainly metabolized to thioether-rabeprazole via a non-enzymatic pathway and partially metabolized to demethylated-rabeprazole by CYP2C19 in liver. CYP2C19 status may affect cure rate for Helicobacter pylori infection with proton pump inhibitor triple therapy.Aim. To investigate...

Fusion Engineering and Design > 2001 > 54 > 2 > 321 - 330

In JT-60U, a high-energy neutral beam injection (NBI) program using negative-ion based NBI (N-NBI) for non-inductive current drive and core plasma heating studies in high-density plasma has progressed. The target performance of the N-NBI is a neutral beam injection power of 10 MW for 10 s at 500 keV. A neutral beam power of 5.2 MW at 350 keV with deuterium has already been injected into JT-60U plasma...
