about Cognitive image was 0.512. Coefficient of determination R² which measure explanation of model was 0.262. It means Regression Model reflects real circumstance about 26.2%. The influence of PPL effect about Emotional image was 0.616. It means that PPL effect have an effect on Emotional image more than Cognitive image. R² is 0.380, Regression Model reflects real circumstance about 38%.
Comprehend the concept of extraction of organic molecules to the solvent and determine the partitioning coefficient (distribution coefficient) of acetic acid between water and 1-butanol.
If a solute is added to two immiscible solvents, A and B, in contact with each other, the solute distributes itself between the two and equilibrium is set up between the solute molecules in solvent A and solut
the high temperature fluids in the vicinity of the heated plate and introduce the low-temperature ambient fluids into the region behind the promoters.
The optimum height and the attack angle that make the overall heat transfer coefficients a maximum were determined for the present promoters and they are H=10mm and α=90 degrees, respectively, within the range of the present experiments.

2-1-1. Principle
“Developed a theoretical model to evaluate the overall heat transfer coefficient, considering both conduction through the solid and heat exchange from the solid surface to the gas.”
An accurate determination of the geometrical parameters of the foam was considering the difference in the pore size and the measured value res

determined by the quality factor, Q, following the expression △f=f/Q. The quality factor quantifies the energy dissipation and is defined as the ratio between the mechanical energy accumulated and dissipated per vibration cycle. Under liquids environments, the quality factor shifts toward much lower values than in air, due to the damping effect of the viscous surroundings, which decrease abrupt

determined by solving a characteristic equation, and using the characteristic roots together with the assumed form of the solution the solution is given with two undetermined coefficients. The particular solution is found by substituting the assumed form of the particular solution into the equations and solving a linear system of equations. Finally the unknown coefficients are determined from the
