Electrical characterizations of MgO-ZrO2 high temperature sol-gel insulations coatings on different types of epoxies

The sol-gel MgO-ZrO2 electrical insulations were coated on Stainless-Steel-304 (SS) tapes by reel-to-reel process for investigation of electrical properties under various pressure at room temperature (298 K) and liquid nitrogen temperature (77 K) for HTS/LTS high field insert coil. Solutions consist of Mg and Zr based precursors, solvent and chelating agent. The electrical insulation was made on long-length SS substrate. Insulation thickness for 4, 8, and 9 dippings were determined 7, 12, and 13 mu m, respectively. Three different types of stycast, 2850 FT/24 LV Black and Blue, and White Buecher Epoxide Resin were studied. Stycast thicknesses were varied from 33-20 mu m, when the pressure was applied from 0 to 0.54 GPa. The thicknesses of high temperature insulation coatings and epoxsies were measured by using Environmental Scanning Electron Microscope (ESEM). Resistance, capacitance and High Voltage Breakdown (HVbd) Of the samples were measured by using standard machines Model 6517A Electrometer/High Resistance Meter, 161 analog digital capacitance meter and Model 200-02R High Voltage Power Supply, respectively. The results were presented graphically

Nonvacuum deposition of silver doped YBCO coated conductor on %100 lattice match buffered Ni tapes

Silver doped YBa2Cu3O7-delta (YBCO) coated conductors were fabricated on Gd1.624Ho0.O-376(3) (100 % lattice match with YBCO) textured buffer layers on Ni tape by reel-to-reel sol-gel dip coating system. Sample were prepared with different wt(1-5) % Ag doped ratio. The surface morphologies and microstructure of all sample were characterized by ESEM, EDS and XRD. Pole figure texture analyses have been done to characterize texture of buffer layer and YBCO superconducting film. The critical current I-c measurement was performed using four wire method with the 1 mu V/cm criterion. The critical current density, J(c) was measured to be 2.2 x 10(4) A/cm(2) at 77 K self field for 1 wt % Ag doped YBCO sample

JAK2(V617F) Mutation Is Not Associated with Thrombosis in Behcet Syndrome

WOS: 000305797100012PubMed ID: 22203033The Janus kinase 2(V617F) (JAK2(V617F)) mutation is an acquired genetic defect that is considered to enhance thrombosis in Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs). Thrombosis is also a well-defined component of Behcet syndrome (BS). The aim of this study was to determine the frequency of JAK2(V617F) mutation in BS-associated thrombosis. A total of 152 patients with BS (62 with thrombosis and 90 without thrombosis) were enrolled. An additional 186 patients with MPNs and 107 healthy blood donors were included to serve as diseased and healthy controls, respectively. None of the patients with BS and healthy controls carried the JAK2(V617F) mutation, whereas 67% of patients with MPNs were positive for JAK2(V617F). The frequency of thrombosis in patients with MPNs was not statistically different between carriers and non-carriers of JAK2(V617F) mutation. Our data suggest that JAK2(V617F) is not directly related to thrombosis in MPNs and in other thrombotic entities, such as BS.Eczacibasi-Baxter Hospital Supply Inc.; Berk Ilac A.S.The author(s) disclosed receipt of the following financial support for the research, authorship and/or publication of this article: This study was partially funded by the unrestricted grants of Eczacibasi-Baxter Hospital Supply Inc. and Berk Ilac A.S

Genome-wide association analysis identifies new susceptibility loci for Behçet's disease and epistasis between HLA-B*51 and ERAP1

Patients with Behçet's disease (BD) suffer from episodic inflammation often affecting the orogenital mucosa, skin, and eyes. To discover new BD-susceptibility loci, we performed a genome-wide association study (GWAS) of 779,465 SNPs with imputed genotypes in 1,209 Turkish BD patients and 1,278 controls. We identified novel associations at CCR1, STAT4, and KLRC4. Additionally, two SNPs in ERAP1, encoding ERAP1 p.Asp575Asn and p.Arg725Gln, recessively conferred disease risk. These findings replicated in 1,468 independent Turkish and/or 1,352 Japanese samples (combined meta-analysis p < 2 × 10(−9)). We also found evidence for interaction between HLA-B*51 and ERAP1 (p = 9 × 10(−4)). The CCR1 and STAT4 variants were associated with gene expression differences. Three risk loci shared with ankylosing spondylitis and psoriasis (MHC-I, ERAP1, and IL23R, and the MHC-I-ERAP1 interaction), as well as two loci shared with inflammatory bowel disease (IL23R and IL10) implicate shared pathogenic pathways in the spondyloarthritides and BD
