An important mechanism is the reduction of the drug's particle size to the microcrystalline or molecular level for rapid dissolution and absorption.
Similar results were found when using Aerosil® R972 as the adsorbent (data not shown).
The typical peaks of nifedipine were still found in the physical mixture (data not shown) and in the ternary solid dispersion at the ratio of 1:0.5:1, 1:1:1 and 1:2:1.
However, the peak intensity was lower when the ratio of Eudragit® E was higher, resulting from a reduction in the crystallinity of the drug in the ternary systems.

They could not observe any reduction of the activation energy with increasing electric field applied and concluded that the charge state after emission of an electron is very likely a neutral one and the defect state corresponds to a deep acceptor.
(3) The fit-curves of Eq. (3) to the experimental data are shown as solid curves in Fig. 3.
The solid straight line is a linear fit to the data with a slope of -2.0 meaning that s ~ T-2.0.
A barrier of 40 meV was assumed, which corresponds to the Poole-Frenkel reduction of the activation energy of the EH6-center assuming a donor-like nature [4].
It is clearly demonstrated that this model does not reproduce the experimental data.

Both Peng-Robinson EOS and NRTL equation gives an error of standard deviations within 2% compared to experimental data.
Their experiment data also were correlated with Peng Robinson equation of state and used to obtain the binary interaction parameters [23].
The calculations using the algorithm were compared with the data obtained in a pilot scale absorber with ceramic Intalox saddles as packing.
Several correlations for mass transfer coefficient and interfacial area estimation was also tested with the experimental data [37].

The EBSD
data was acquired in the radius (R) plane, i.e. the plane containing the Z and rotation (θ) specimen
directions, using an FEI Sirion FEGSEM equipped with a HKL Nordlys CCD camera controlled by
HKL Channel 5 acquisition software.
The EBSD acquisition data for the forward/forward and forward/reverse specimens were collected with a step size of 0.25µm; the total area analysed for the former was 0.24 mm2 whereas for the later, the total area scanned was 0.49 mm 2.
Subsequent data analysis was performed using HKL Channel 5 software and VMAP V.8 kindly provided by Professor F.J.
The data presented here also corresponds nearly exactly with the data of Lopez-Pedrosa et al. [8] for AA1200 deformed at the same temperature to the same strain and the data of Hughes and Hansen [9], for room temperature deformed nickel deformed to slightly lower strain levels.
The current data set is insufficient to come to these same conclusions but the 100 µm 100 µm 100 µm 100 µm (a) (b) (c) (d) trend looks similar.

In regards to the data obtained the sewage incoming flow to the biological treatment stage (aeration tank num.5) in Kolomna is almost constant, 60000 m3 per day in average.
In regard with the sanitary-chemical data obtained it became possible to make calculations and conclusions about the biochemical system specific for the regard facility.
According to the data obtain an average oxidation velocity for a particular treatment period amounts 6.9 mg BOD/g h.
The data obtained reveals the fact that activated sludge in this system has a load-illness (it is so called hungry sludge).
Backward nitrification makes denitrification reaction low down, which was also confirmed by data obtained.

The above sorbents to adsorb acetone, 1-butanol, and ethanol for single-component adsorption using adsorption equilibrium apparatus will be conducted and the isotherm data will be obtained.
Earlier studies obtained only equilibrium adsorption isotherm data.
The isotherm data were obtained in this study as well as the development of regression models for the isotherm data.

However, after the capacitance
change is initiated further decrease occurs at the same rate in both the cases as shown in panel (b) of
Figure 7, by time-shifting the NOA data.
This results in an acceleration of TBR and reduction of the delay time.
The data is well described by a sigmoidal function, shown as solid line through the data.
In combination with the data presented in Figure 8, these observations suggest that the random dilution-random field crossover is perhaps a universal feature. 30 40 50 4 8 12 15 V 10 V 40 V ε T ( o C) 20 V Figure 9: Influence of the applied voltage on the photoinduced N-I transition.
Acceleration of TBR by an external field Fixed frequency dielectric constant data obtained for a planar sample (having positive εa) in the absence of an electric field (except for the probing field) and with DC voltages of different magnitude are shown in Figure 9 [23].

Data acquisition
The signals obtained from the sensors installed in the test bench were acquired using a data acquisition system and stored in a data file.
To perform the data acquisition, a program written using LabVIEW software was used with a NIUSB6211 multifunction signal acquisition board.
Experimental results The tests were performed, and the COP data are shown in Table 2.
Table 3 presents the data for the city of Belo Horizonte, in the Southeast.
For the city of Belo Horizonte were used the following data: Latitude ˚N -19,8, Longitude ˚E -43,9, and Value of the 0,60929 US$ / kWh.

Wijay and Spatz [2] reported data taken with refrigerants R-22 and R-410A inside horizontal smooth tube.
All signals of temperatures, pressure drop and mass flow rate were collected using a data acquisition system in real time with a PC running the data reduction program.
Data reduction The local flow condensation heat transfer coefficient as obtained as: Where is the heat transfer coefficient for two-phase refrigerant, .
The data show that the condensation coefficient increase with increasing mass velocity and vapor quality.
A general correlation was made by modifying Shah [7] correlation based upon the experimental data.
