Ain El Bey Road, 25000 Constantine, Algeria a*salah_mot@outlook.com, bf_kerrour@yahoo.fr Keywords: Pressure sensor, Complementary metal oxide semiconductor (CMOS), Suspended gate MOSFET, Microelectromechanical systems (MEMS),COMSOL software.
For instance, Svensson et al. [9] presented a surface-micromachined pressure sensor based on a FET device, in which the diaphragm acted as the transistor gate.
Other researchers Ching-Liang Dai et al. [10] opted to utilize the commercial 0.35 nm complementary metal oxide semiconductor (CMOS) process and a post-process to fabricate the micro FET pressure sensor, where the sensor is composed of 16 sensing cells in parallel and each sensing cell includes a suspended membrane and an NMOS.
Ajay et al. [7] developed a novel MOSFET-based sensor, which exploits both the channel piezoresistance and capacitance variation effects on MOSFET.

For Inconel 718 alloy with CO2 and Nd:YAG lasers [12]: (1) For Ti-6Al-4V alloy with CO2 laser [9]: (2) For hardened steel with CO2 laser [14]: (3) For hardened steel with CO2 and Nd:YAG lasers where [14]: (4) For Waspaloy with CO2 and Nd:YAG lasers where [19]: (5) For SiCp/Al composites with CO2 laser [20]: (6) For Al2O3 fibre reinforced Al-2% Cu composite with CO2 laser [21]: , (7) where, and are laser power (W) for the CO2 laser (heating the graphite coated workpiece surface) and Nd:YAG laser (heating the machined chamfer) respectively, is the diameter of the workpiece (mm), is the feed (mm) and is the cutting speed (m/min).
It is found to be 250°C for Ti-6Al-4V alloy [9], 340°C for austenitic stainless steel [13], 300°C for SiC/Al MMCs [20], the range of 360-540°C for Inconel 718 alloy [12] and between 300 and 400°C for Waspaloy [19] in turning operation.

Ostasevicius et al. [6] reported results of squeeze film damping effects on free and forced vibrations of micro-cantilever, which performed by using COMSOL®.
Sudipta et al.[7] used ADINA® for analyzing the hydrodynamic loading of elastic microcantilevers vibrating in viscous fluids, where a 3D finite element fluid-structure interaction model had been build for computing the quality factors and added mass coefficients of several modes.

Hadiyanto et al [17] have used ethanol to extract phycocyanin.
Safi et al (2014) used ultrasonication with distilled water to obtain higher protein yield (47.10 %) but this previous study requires high energy due to the freeze drying process [10], while the recent study used conventional sun drying process.
