Aprea et al. [4] studied the influence of adopting an IHX on the coefficient of performance from a thermodynamic point of view, assuming no pressure loss.
Domanski et al. [5] showed that the benefits of application of the suction-liquid line heat exchanger depend on a combination of operating conditions and fluid properties.
Mastrullo et al. [6] presented a chart for predicting the effectiveness of IHX installation for 19 different ozone friendly fluids, and concluded that the advisability of the IHX installation can be evaluated as a function of thermodynamic properties.
Bahrami at el. [2] studied a designed internal heat exchanger for R134a automotive air conditioning system.

In 2009, Mai et al reported that the flower of Etlingera elatior contains 1.05mg of cyanidin-3-glucoside per 100g of fresh plant.
The absorption peak at 534nm may attributes to the betanin content in the leaf of the Amaranthus spp. as reported by Stintzing et al.[2004].
It can be seen that Duranta erecta and Amaranthus spp had lower current density which may be due to the less available bonds that can be occured between the dye molecules and TiO2 semiconductor surface as reported by Garcia et al., [2003] and thus less electrons transfer from the dye molecules to the TiO2.

In this study, the equivalent flow stress is approximated using the following equation, which was proposed by Sheppard et al. [7]
Because the most of heat is generated as the result of friction between the target material and the shoulder of FSW tool in FSW, Figarrd et al. proposed that the heat input unit time q (W) can be described as the following equation which can be derived by the simple mathematical model [10] (4) Where, m, P, N and r are coefficient of friction, compressive load (N/m), rotational speed (s-1) and radius of shoulder (m), respectively.
