And then, other main types of solar absorption cooling systems based on double-effect, half-effect and two-stage absorption chillers were summarized.
EC50 (half-maximal effective concentration) and n denote the toxin concentration of half-maximal effect and the Hill coefficient, respectively.
where Emax and Emin are the top and bottom asymptotes of the response, y is the inhibition rate when the concentration of the inhibitor is [I], EC50 is the concentration of inhibitor at half-maximal effect, and n is the slope parameter like the Hill coefficient [47].
Non-linear least-square curve-fitting was carried out with Origin 8 software (OriginLab) using a standard Hill equation: f(x) = Max/[1 + (EC50/x)h] where x is the concentration of a ligand, Max the asymptotical maximal effect, EC50 the concentration for half-maximal effect, and h the Hill coefficient.
The degree of enzyme induction can be characterized by the parameters such as EC50 (concentration causing half-maximal effect) and Emax (maximum effect) determined in in vitro studies.
Curves were constructed and analyzed by fitting sigmoidal dose-response curves using the GraphPad Prism 4 program (GraphPad Prism Software Inc) to obtain potency (EC50, concentration of the ligand to give half-maximal effect) and efficacy (Emax, % maximal stimulation over basal activity) values.
Agonist concentration-effect curve data were fitted to the Hill equation using an iterative, least squares method (GraphPad Prism, San Diego, CA, U.S.A), to provide estimate EC50 (the agonist concentration that induces half-maximum effect) and presented as -log10 (pEC50) which is normally distributed.
10 Sotagliflozin was delivered once in the afternoon by oral gavage at a dose of either 2 mg/kg or 30 mg/kg in a 10 mL/kg total volume; these doses were chosen because in past mouse studies, 2 mg/kg had a half-maximal effect and 30 mg/kg a maximal effect on urinary glucose excretion.
The plasma concentration of E7820 was defined as cp, and Emax,I, IC50 and γ were the maximal drug effect, the plasma concentration at half maximal effect, and the shape exponent of the Hill equation describing the drug effect on the α2-integrin expression rate, respectively.
Half-effect absorption chillers and two-stage absorption chillers seem to be more suitable for air-cooled solar absorption cooling systems in hot and dry regions which are short of water.
It was two hours and forty-six minutes long, filled with half-realized effects, and had only twenty minutes of music.
