A linear-exponential equation was used to describe the different disintegration curves with good fit.
The difference in the disintegration curves was hypothesized due to the competition between surface erosion and texture softening.
The number of MDA-MB-435 cells that had invaded the MCF-10A monolayer was calculated by measuring the incorporated H-thymidine for each MCF-10A monolayer in a Packard TopCount NXT® microplate scintillation counter (Packard Instruments, Inc., Palo Alto, CA, USA), and the number of cells present computed using the standard curve of disintegrations per min/cell for each treatment.
The disintegration profiles and fitted model curves (Eq. 3) are shown in Figure 3.
As a result, the curve between the observed disintegration rate as a function of the beta efficiency parameter can be simulated.
It is further evidence that those who predicted a disintegration of the euro, were indeed behind the curve and simply wrong," said Olli Rehn, the commissioner for monetary affairs.
For erosion-dominant disintegration, the weight retention ratio vs. disintegration time curve can be expressed with exponential, sigmoidal, and delayed-sigmoidal profiles.
The time-activity curves were fitted by exponential curves (least mean squares fit), and the area under the curve was calculated giving the total number of disintegrations (NOD) occurring in the respective organ during the time of investigation.
While negligible changes in both the soil structure and θ were observed following slow wetting, fast wetting resulted in disintegration of aggregates and drastic changes in the shape of the θ curve.
The bulk density (BD), soil moisture retention curve (SMRC), field capacity (FC), saturated hydraulic conductivity (Ks) and soil disintegration rate (SDR) at the depths of 0 20 cm, 20 40 cm, 40 60 cm and 60 80 cm at each sampling point were measured, and soil pore size distribution (PSD) based on SMRC was analyzed.
