TL;DR: In this article, a method of barcoding data needed to determine a calibration curve for a test element in an analyzer is described, which follows the steps of ascertaining by statistical analysis the ranges of values for R that are possible for three given concentration values C1, C2 and C3, for a given assay, and assigning a high value H and a low value L for these ranges.
Abstract: There is described a method of barcoding data needed to determine a calibration curve for a test element in an analyzer The process follows the steps of: a) ascertaining by statistical analysis the ranges of values for R that are possible for three given concentration values C1, C2 and C3, for a given assay, and assigning a high value H and a low value L for these ranges; b) calculating for a given lot of the given assay, a calibration curve that correlates the analyzer response to the concentration, c) determining the analyzer response R1, R2 and R3 from said calibration curve, that corresponds to the C1, C2 and C3 values; d) calculating the bar code value B1 for Ri of each of these R1, R2 and R3 from the equation: (2) Bi = (10n - 1)(Ri - Li)/ (Hi-Li) where Ri is R1, R2 or R3, and Li and Hi are the corresponding L and H values for that Xi; e) rounding Bi to the nearest integer;and f) supplying this value of Bi for each of Ri = R1, R2 or R3 in bar code form, using n-digit decimal numbers, so that only three sets of (10n) possibilities are needed to accurately pass along data corresponding to the calibration coefficients even though each of the three coefficients can vary by more than that which can be specified using 10n digits

TL;DR: The calibration reproducibility of an intra-laboratory study is assessed and the turbidimetric and nephelometric results are compared with those provided by the proposed method, which is relatively simple and affordable.
Abstract: The McFarland method allows the concentration of bacterial cells in a liquid medium to be determined by either of two instrumental techniques: turbidimetry or nephelometry. The microbes act by absorbing and scattering incident light, so the absorbance (turbidimetry) or light intensity (nephelometry) measured is directly proportional to their concentration in the medium. In this work, we developed a new analytical imaging method for determining the concentration of bacterial cells in liquid media. Digital images of a series of McFarland standards are used to assign turbidity-based colour values with the aid of dedicated software. Such values are proportional to bacterial concentrations, which allow a calibration curve to be readily constructed. This paper assesses the calibration reproducibility of an intra-laboratory study and compares the turbidimetric and nephelometric results with those provided by the proposed method, which is relatively simple and affordable; in fact, it can be implemented with a digital camera and the public domain software ImageJ.

TL;DR: In this article, a method of simultaneous measurement of velocity and temperature of water has been developed using a modified laser induced fluorescence of Rhodamine B, which decreased with temperature and its temperature with a coefficient of 32%/K.
Abstract: A method of simultaneous measurement of velocity and temperature of water has been developed using a modified laser induced fluorescence of Rhodamine B The intensity of fluorescence decreased with temperature and its temperature with a coefficient of 32%/K The dimensionless calibration curve was not affected by laser intensity, concentration of Rhodamine B, laser wavelength and optical configuration Simultaneous measurement of velocity and temperature was made in a natural convection field
