Development of UPS-SMES as a protection from momentary voltage drop

We have been developing the UPS-SMES as a protection from momentary voltage drop and power failure. The superconducting system is suitable as electric power storage for large energy extraction in a short time. The most important feature of superconducting coil system for the UPS-SMES is easy handling and maintenance-free operation. We have selected low temperature superconducting (LTS) coils instead of high temperature superconducting (HTS) coils from the viewpoint of cost and performance. However, it is difficult for the conventional LTS coils to fulfill maintenance-free operation since the cooling methods are either pool boiling with liquid helium or forced flow of supercritical helium. Thus, a conduction cooled LTS pulse coil has been designed as a key component of the UPS-SMES. The development program of 1 MW, 1 sec UPS-SMES is explained

Development of 1 MJ Conduction-Cooled LTS Pulse Coil for UPS-SMES

A 1 MW, 1 s UPS-SMES is being developed for a protection from a momentary voltage drop and an instant power failure. As a key technology of the UPS-SMES, we developed a prototype LTS pulse coil with a stored energy of 100 kJ and conducted cooling and excitation tests in 2005. The operation test of the prototype UPS-SMES using this 100 kJ coil with power converters have been performed in 2006. A 1 MJ coil was designed before the fabrication of the 100 kJ prototype coil. The superconductor, the electric insulation technique, the winding method, and the cooling structure used for the 100 kJ coil were based upon the 1 MJ coil design. The successful performance test results of the prototype 100 kJ coil validated the design concept and fabrication technique of the 1 MJ coil. According to the achievement of the prototype 100 kJ UPS-SMES, the 1 MJ conduction-cooled LTS pulse coil has been fabricated successfully. The successful experimental results of the 100 kJ prototype coil with power converters and the fabrication procedure of the 1 MJ full size coil are described

Dissetion of Superior Mesenteric Artery which Required resection of a Large Amount of the Small Intestine and the Colon : A Case Report

Superior mesenteric artery (SMA) dissection is rare. We herein report about a case of SMA dissection which required resection of a large amount of the small intestine and the colon. A 59-year-old male with vague lower abdominal pain and diarrhea was admitted to our hospital. An erect abdominal X-ray showed niveau. His condition deteriorated and on the fifth day from the onset, an enhanced computed tomography (CT) revealed the SMA was dissected along 3 cm of its length from its origin, and the blood supply to the small intestine was shuttered in association with false lumen formation. Finally, the patient was necessitated an emergency surgery. A grayish ischemic small intestine and ascending colon were seen along with a moderate amount of ascites. The ischemic part of the intestine was resected. Pathological findings revealed coagulation necrosis with inflammatory cell infiltration, blood congestion, and hemorrhage. This coagulation necrosis was compatible with hemorrhagic necrosis due to intestinal ischemia. In conclusion, enhanced CT was available for detecting SMA dissection. If a patient with acute abdomen of unknown origin is encountered, SMA dissection should be ruled out, because ischemic intestine due to SMA occlusion is time-dependent and life-threatening. Furthermore, in the case of extensive bowel resection, the management of short bowel syndrome is thought to be essential

Genome-wide association studies identify IL23R-IL12RB2 and IL10 as Behçet`s disease susceptibility loci

Behçets disease is a chronic systemic inflammatory disorder characterized by four major manifestations: recurrent ocular symptoms, oral and genital ulcers and skin lesions1. We conducted a genome-wide association study in a Japanese cohort including 612 individuals with Behçets disease and 740 unaffected individuals (controls). We identified two suggestive associations on chromosomes 1p31.3 (IL23R-IL12RB2, rs12119179, P = 2.7 × 10−8) and 1q32.1 (IL10, rs1554286, P = 8.0 × 10−8). A meta-analysis of these two loci with results from additional Turkish and Korean cohorts showed genomewide significant associations (rs1495965 in IL23R-IL12RB2, P = 1.9 × 10−11, odds ratio = 1.35; rs1800871 in IL10, P = 1.0 × 10−14, odds ratio = 1.45).Remmers EF, 2010, NAT GENET, V42, P698, DOI 10.1038/ng.625Meguro A, 2010, ANN RHEUM DIS, V69, P747, DOI 10.1136/ard.2009.108571Hirschfield GM, 2009, NEW ENGL J MED, V360, P2544, DOI 10.1056/NEJMoa0810440Fei YP, 2009, ARTHRITIS RES THER, V11, DOI 10.1186/ar2695Isomura M, 2008, CLIN CANCER RES, V14, P6683, DOI 10.1158/1078-0432.CCR-07-4389Rueda B, 2008, ANN RHEUM DIS, V67, P1451, DOI 10.1136/ard.2007.080283Liu Y, 2008, PLOS GENET, V4, DOI 10.1371/journal.pgen.1000041Purcell S, 2007, AM J HUM GENET, V81, P559, DOI 10.1086/519795Cargill M, 2007, AM J HUM GENET, V80, P273Wallace GR, 2007, HUM IMMUNOL, V68, P122, DOI 10.1016/j.humimm.2006.11.010Duerr RH, 2006, SCIENCE, V314, P1461, DOI 10.1126/science.1135245Price AL, 2006, NAT GENET, V38, P904, DOI 10.1038/ng1847Iwakura Y, 2006, J CLIN INVEST, V116, P1218, DOI 10.1172/JCI28508Barrett JC, 2005, BIOINFORMATICS, V21, P263, DOI 10.1093/bioinformatics/bth457Chang JT, 1999, J EXP MED, V189, P969Kaklamani VG, 1998, SEMIN ARTHRITIS RHEU, V27, P197Turner DM, 1997, EUR J IMMUNOGENET, V24, P11990, LANCET, V335, P1078MIZUSHIMA Y, 1988, INT J TISSUE REACT, V10, P59OHNO S, 1982, ARCH OPHTHALMOL-CHIC, V100, P14553
