In 1978, Pendle et al. reported that the mechanical stability of CNRL depends on various factors.
Nithiuthai et al. (1995) [4] investigated on accelerating MST of CNRL by adding carboxylated soap.
Tanaka el al. (1997) [6] investigated the method for preserving the stability of CNRL which has low protein content by adding stabilizer including a negative surfactant, an amphoteric surfactant, a nonionic surfactant, and an oligomer or amphoteric polymer.
In 2009, Silva et al. [7] investigated on the effect of adding ammonium laureth soap on CNRL.
Sansatsadeekul et al. (2011) [8] investigated the characteristics of protein and phospholipid on CNRL.

Following [13], we consider angle to the left (AL), angle to the right (AR), opening on the left (OL), opening on the right (OR), and X-crossing (CX).
Selected experimental results for test sets T(AL), T(AR), T(OL), T(OR), T(CX) are given in Table 3 and Table 4.

Introduction Ever since the Transformation-Induced Plasticity (TRIP) effect was first reported by Zackay et al. [1] more than 50 years ago, significant research efforts have been directed towards understanding the mechanism and on the design of steel compositions and processing routes for its best utilisation.
As a result, TRIP steels with lean compositions containing 0.15-0.2C-1.5-2Mn-1-1.5Si (wt.%) as the main elements and possible alloying additions of Al, Nb, Mo and P have been developed [2-5].
Experimental Procedures Three experimental TRIP steels with alloying additions of Al, Mo and Nb were used in this study (Table 1).

Roger et al [9] demonstrated that cellulose could be dissolved in ionic liquids without any prior activation or pretreatment.
Zhang et al [11] synthesized wool keratin / cellulose composites membrane usingBmimCl ionic liquids.
Antal at el [17] reported that the activation energy, pre-exponential factor and reaction order separately for nitrogen and steam pyrolysis of cellulose were: 36.6 kcal/mol, 6.06 x109sec-1, 0.46 and 34.2 kcal/mol, 1.67 x 109 sec-1, 0.51 respectively.
In spectra (A) the typical diffraction peaks at 2-theta 15.1°, 22.2° of cellulose Ι as discovered earlier by Takahashi et al. [24] are observed.

Specifically, the work of Morel et al. [15] showed that sonochemical method to be an easy, rapid and effective method of synthesizing silica coated magnetite nanoparticle using Stöber process.
Similar to the report of Tombacz et al [24], we observed the Point Zero Charge (PZC) of SPION (condition when the electrical charge density on a surface is zero) to be around pH 8.
In line with the work of Park et al. [28], the XRD peaks pattern confirmed the formation of silica coated SPION.
