The theoretical results show good agreement with the experimental data, and the ligand contributions should be considered due to the strong covalency of the systems.
(1) Here gs (» 2.0023) is the spin-only value. z and z' are the spin-orbit coupling coefficients, k and k' are the orbital reduction factors, and P and P’ are the dipolar hyperfine structure parameters for a 3d8 ion in crystals. k is the core polarization constant.
Utilizing the cluster approach containing the ligand p- and s-orbital contributions [18], the spin-orbit coupling coefficients, the orbital reduction factors and the dipolar hyperfine structure parameters can be expressed as: z = Nt (zd0 + lt2 zp0 /2) , z' = (Nt Ne)1/2 (zd0 - lt le z p0 /2) , k = Nt (1 + lt2 / 2 ) , k’ = (Nt Ne)1/2 [1- lt (le+ ls A)/2] , P = Nt P0 , P’ = (Nt Ne)1/2 P0
The group overlap integrals, the cubic field parameter Dq (in cm-1) and the average covalency factor N, the molecular orbital coefficients Ng and lg (and ls), the spin-orbit coupling coefficients (in cm-1), the orbital reduction factors and the dipolar hyperfine structure parameters (in 10-4 cm-1) for the Fe0 and Mn- centers in Si.
Based on the present cluster approach calculations, the anisotropies (or the relative differences L’/L - 1, with L= k and z) are about 40% - 98% and 14% - 70% for the orbital reduction factors and the spin-orbit coupling coefficients, respectively.

Scoring of the PET surface is eliminated and the workpiece (PET) feed rate can be higher with a consequent reduction in production costs.
Data have shown that the size of the gap between the electrode and workpiece directly influences the current flow and discharge of electrolyte dregs in the electrochemical process [11].
An effective precision recycling process is a very important development for the semiconductor industry to offset the obvious low yield and effect a reduction of material costs [12].
The reduction in surface thickness of the PET diaphragm after micro-electrochemical etching (μ-ECE) of the Indium-tin-oxide (In2O3SnO2) nanostructure was 20nm.
This development will allow defective products to be reclaimed and returned to the production line with subsequent reduction of costs in the optoelectronic semiconductor industry.

It can be seen that CAP exhibited one set of well-defined reduction peak at -0.75 V on the bare glassy carbon electrode.
Only reduction happened to CAP, and there was no an additional oxidation peak, which demonstrated the electrode reaction is a completely irreversible process.
Furthermore, the current of the reduction peak of CAP on dsDNA/HAp/GCE was significantly increased.
The reduction peak currents of TAPP increased with scan rate from 50 to 250 mV·s-1.

Kadota. et al. 2002) This results in the significant reduction of the intensity of the liquid phase pyrolytic reactions, which may lead to the formation of carbonaceous residue.
The reduction in the formation of carbonaceous residue is expected to be more remarkable.
The picture of fig4 shows the different effects of our “improved detergent additive” and the common detergent additive in reduction of exhaust emission.
The data of common detergent additive is cited from a well-known detergent additive manufacturer’s manual.It is clear that control the quenching effects in gasoline engine can bring remarkable benefit in reducing emission of UHC and CO.
New emerging additives should not only possess both keep “clean” and “clean up” properties but also have remarkable characteristics of exhaust reduction.

A plasticity model based on tensile test data was adopted as a material model for simulation.
Modeling Details Material data The flow stress behavior at a strain rate of 10-3 s-1 during tensile testing can be characterized by a plasticity model [8] given by equation: σ=65-45exp-29ε (1) where σ is the flow stress during deformation, and ε is the plastic strain.
From the experimental results, the thickness reduction of 54 % is also found at this corner.
Table 4 presents the forming strain rate data obtained from the simulations.
Simulations showed the presence of localized thinning areas, where the forming sheet had started thinning (22 % thickness reduction) during hot drawing.
