An analytical evaluation of the thyroid stimulating hormone (TSH-3) assay on the Bayer ADVIA Centaur immunoassay system was performed. General analytical requirements (linearity, resistance to typical interferences, absence of a carry-over effect) were fulfilled and reproducibility was satisfactory. Inter-assay coefficient of variation (CV) of a human serum pool with a concentration of 0.014 mU...
BACKGROUND Evidence exists that during pressure support ventilation (PSV), the addition of an extrinsic (ie, ventilator-generated) breath-to-breath variability (BBV) of breathing pattern improves respiratory function. If BBV is beneficial per se, choosing the PS level that maximizes it could be considered a valid strategy for conventional PSV. In this study, we evaluated the effect of different...
Common wild rice (Oryza rufipogon Griff.) is important to broaden the narrow genetic diversity of cultivated rice. To better understand the genetic variation, heritability and genetic correlations of agronomically important traits, 156 F2:3 families derived from the cross between rice (Oryza sativa) and wide rice (O. rufipogon Griff.) were evaluated under field conditions. The Analysis of Varia...
An analysis of the variation in magnitude of EEG signals in various frequency bands of anesthetized patients and normal sleeping volunteers was carried out. The coefficient of variation (CoV), i.e. the standard deviation/mean, within 10 second epochs was found to be quite constant throughout the whole of the EEG recordings and was typically about 0.46. This was found to be the case for both the...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
the selection of high yielding varieties with good stability is an important objective in rice breeding programs. the grain yield of eight rice lines with a check (nemat) were compared on six locations of gilan and mazandaran provinces during two years, using rcbd with four replications. combined analysis of variance showed that the effect of variety and year × location × variet...
BACKGROUND Numerous events may occur during a haemodialysis session, leading to variation in the quantity of dialysis received. The purpose of this study was to identify risk factors for variability in haemodialysis delivery. METHODS Variability in dialysis delivery was expressed by the coefficient of variation (CV%) and calculated for the volume of blood processed (VBP) for all treatments an...
Methods: Thirteen analytes were measured using serum from dogs and cats. Observed total error (TEo) was calculated based on coefficient of variation (CV) and bias. TEo was compared with allowable total error (TEa). Canine and feline samples were collected and measured in five small clinical sites and one reference site. Passing-Bablok regression and Bland-Altman analysis were used to compare PT...
