Development and validation of an HPLC-DAD analytical method for quantitative and simultaneous determination of cefoperazone and prednisolone in intramammary ointment by Patrícia Espinosa dos Santos, Jefferson Annunciatto, Teófilo Fernando Mazon Cardoso, Marcos Serrou do Amaral, Nájla Mohamad Kassab

“…The method was applied in intramammary ointments, showing linearity, for CPZ, from 0.25 to 25 μg mL-1 (r=0.9999); and, for PRED, from 0.75 to 30 μg mL-1 (r=0.9997), with low limits of detection and quantification, precision with coefficients of variation less than 2%, in accuracy, presented recovery close to 100% for both drugs, in addition to demonstrating their robustness by the Youden test, which evaluated the effects and concluded that the altered parameters in the test were not sufficient to change the values obtained in the determinations. …”

Relationship between radon and oxygen diffusion coefficients in OPC concretes by P. Linares-Alemparte, M. Souto-Allaoui, C. Andrade-Perdrix

“…As concrete often forms the building envelope with the ground, it is interesting to investigate its performance as a barrier, i.e. its radon exhalation, which depends on the radon diffusion coefficient and thickness. Experimentally obtaining the radon diffusion coefficient in concrete is complicated, so it would be useful to be able to use an analytical method for its estimation from parameters that are easier to obtain, such as the oxygen diffusion coefficient, which can be determined experimentally with less difficulty and could even be estimated analytically. …”
