With the argument var.equal=FALSE (default), the t-test for … WebMay 6, 2024 · The C / T ratio of our hospital in the studyperiod was found to be 1.08 x 100. This ratio complies with the <2 standard, which is an indicator of effective functioning of blood centers. DISCUSSION. The aim of this study is to evaluate the C/T ratio, which is a new indicator used in blood transfusion centers, in different clinics in our institution.

WebDec 1, 2016 · The influence of imperfections on the instability bending moment of thin-walled straight pipes with D/t-ratios (D - outside diameter, t - wall thickness) up to 140 is determined using nonlinear Finite Element (FE) analyses. The analyses show that the type and size of the imperfection, the D/t ratio and the material properties have significant … Webthe highest t-ratios may not be highly correlated with expected returns. Contrary to common belief, a high t-ratio may in fact be evidence of low explanatory power. The results in this study cast doubt on the economic significance of variables selected only on the basis of high t-ratios in multivariate regression methodologies and suggest that WebAug 15, 2024 · Abstract. CAR-NK cells show rapid and potent anti-tumor cytotoxic activity even at very low effector-to-target ratios, however, they do not typically expand upon encounter with antigen and lack long term persistence commonly associated with CAR-T cells. Conversely, CAR-T cells generally exhibit persistent killing activity, even though … button for shirts
