By increasing the wall-thinned depth from 0.25 to 0.75, the limit pressures at φ=π/6 decreased about 10~70% with a variation of the wall-thinned angles (2θ/π=1/4, 1/2, 1).

This study was aimed to investigate the effects of the size of material, extraction time (60, 90, 120,150,180 and 210 minutes), water-to-material ratio (5:1, 10:1, 15:1, 20:1, 25:1 and 30:1 ml/g) and extraction temperature (110, 120,130, 140, 150, and 140°C) on the essential oil yield accruing from extraction of white pepper cultivated in Phu Quoc, Vietnam.
However, when this ratio exceeds 20:1 (g/g), the essential oil yield is only 2.4 (mL/g) at a ratio of 30:1 (g/g).

Enhancement in mechanical properties such as tensile strength, Young’s modulus, creep resistance and fatigue resistance is usually the major attraction of Mg MMCs [1].
AlN possessing low density (3.026 g.cm-3), a low coefficient of thermal expansion (4.5 x 10-6 K-1, in the temperature range 293-673 K) and a very good thermal conductivity (150-200 WmK-1) [7], and resistance to thermal shock [8] is one of the potential reinforcements in Mg composites.
