Up to four different
discharge phases within each pulse were identified: (i) the ignition phase, (ii) the high-current metal-dominated phase, (iii) the transient phase, and (iv) the low-current click here gas-dominated phase. The emission of working gas excited by fast electrons penetrating the space in-between the electrodes during the ignition phase spread far outwards from the target at a speed of 24 km s(-1) in 1.3 Pa of Ar and at 7.5 km s(-1) in 1.3 Pa of N(2). The dense metal plasma created next to the target propagated in the reactor at a speed ranging from 0.7 to 3.5 km s(-1), depending on the working gas composition and the pressure. In fact, it increased with higher N(2) concentration and lower pressure. The form of the propagating plasma wave changed from a hemispherical shape in Ar, to a droplike shape extending far from the target in N(2). An important N(2) emission rise in the latter case was detected during the transition at the end of the metal-dominated phase.”
“To compare IgG anti-cyclic citrullinated peptide (CCP) enzyme-linked immunosorbent assays (ELISAs) of second (anti-CCP2) and third generations (anti-CCP3) for the diagnosis of rheumatoid arthritis (RA), an IgA CCP3 ELISA was also evaluated. Combinations of the use of the three tests were evaluated. Anti-CCP2 IgG, anti-CCP3
IgG, and anti-CCP3 IgA antibody levels were determined by ELISAs in the serum of 70 patients with rheumatoid arthritis, BKM120 molecular weight 34 patients with systemic lupus erythematosus (SLE), and 54 normal subjects. We evaluated the serum levels, diagnostic performance, and the use of a combination check details of tests for RA diagnosis. Statistical analyses include receiver operating curves (ROCs) and others. The serum levels were higher in RA patients. Sensitivity, specificity, positive predictive value, negative predictive
value, positive likelihood ratio (LR), and negative LR were, respectively, 78.6%, 94.3%, 91.7%, 84.7%, 13.8, and 0.23 for anti- CCP2 IgG and 82.9%, 93.2%, 90.6%, 87.2%, 12.2, and 0.18 for anti-CCP3 IgG. These values were better than the same statistical tests for anti-CCP3 IgA. ROC analysis showed that anti-CCP2 IgG and anti-CCP3 IgG had good performance and similar areas. Measuring both IgG and IgA anti-CCP tests increases the specificity if both tests were positive and increases the sensitivity if either test were positive. In our population, anti-CCP2 IgG and anti-CCP3 IgG had good diagnostic performance. Anti-CCP3 IgG had 4.3% more sensitivity than the anti-CCP2 IgG test while sustaining high specificity. This and other studies suggest the development of a dual test-CCP3 IgG and IgA that may be a potential diagnostic tool.”
“Radiation grafting of acrylic acid (AA)/N-vinyl pyrrolidone (NVP) binary mixture onto poly(ethylene terephthalate) (PET) knittings was investigated by pre-irradiation technique.
