Modification:Article Title: Energetics and dynamics of the proton shuttle of carbonic anhydrase II Article Snippet: Accordingly, the pH titration curves of His64 and its surrounding were fitted with a nonlinear least-squares regression analysis (Levenberg–Marquardt algorithm) to standard Hendersson-Hasselbalch equations with 2 macroscopic p K a values in a global way using Matlab. Article Title: Influence of Temperature on Soil Dielectric Spectra in the 20 MHz – 3 GHz Frequency Range Article Snippet: Measurement of soil dielectric permittivity is frequently used as a basis for soil water content estimation by many commercial and experimental sensors.. However, the relations between dielectric permittivity and soil water content may be affected by various other factors, including texture, salinity, and temperature.. In this present article, spectra of complex dielectric permittivity of samples of loamy sand, sandy loam, and silt loam soils of various water content and bulk electrical conductivity were measured with the use of a six-cell coaxial transmission-line system in the 20 MHz–3 GHz frequency range at temperatures from 0.5 C to 40 C. The analysis focused on the impact of temperature on: 1) the real part of complex dielectric permittivity; 2) the relations between the real part of dielectric permittivity and volumetric water content; and 3) bulk electrical conductivity estimated from dielectric modeling.
