This observation is in agreement with the report of Yoshihiro et al. [9] who have reported that pre-strain has no effect on the microstructures of HAZ and fusion zone after weld heat-input.
In contrary to the present observation, Hirose and Kobayashi [10], and Krizan et al. [11] have reported increase in hardness values at the weldment after baking treatment of laser beam weld joints.
Similar type of TEM observations have been reported by Long et al. [13] showing dislocations at the edge of the weld nugget.
De et al. [14] have reported that in ULC bake hardening steels, once the formation of Cottrell atmosphere is completed, there is no further increase in strength beyond this.

The dechroming methodology was developed based on described by Catalina et al. [[] M.
Tice, E.L.
One hundred cells were counted per slide, and DNA damage was classified into four categories according to the migration of DNA fragments as described by Kobayashi et al. (1995) [[] H.
This result is greater than the results found by Catalina et al.[9] that found 96% of dechroming after 72h of treatment with hydrogen peroxide.

Kaur et al. [23] obtained a range in band gap between 3.16 and 3.22 eV for the ZnO co-doped with Cu-N atoms, lower than the usual 3.37 eV often found for the ZnO structure.
Meziane et al. [25] found similar values for band gap when using LiCl4 as a precursor for the Li4+ ion, between 3.16 and 3.26 eV.
The film with 10% Li had transmittance close to 90%, similar to the values obtained by [31] when doping ZnO with Al at 1.2% doping.

Sidahmed et al [4, 5] found that the vibration of gear systems showed second-order cyclostationarity, and applied it to the early diagnosis of gear tooth spalling.
Zhu et al [6] studied the application and effectiveness of cyclostationarity from the first order to the third order in gearbox condition monitoring.
Bi et al [7] used the slice of spectral correlation density to extract modulation information from gear vibration signals, and detected gear defects.
Recently, Antoni et al [8-11] did a lot of work on cyclostationary signal analysis, and applied it to diagnosis of gears and other machines.
El Badaoui and CETIM France for providing the gearbox vibration datasets and the anonymous referees for their constructive suggestions.

The expression proposed by Perdew et al. [8] is used for the exchange-correlation energy in the GGA.
Hourai et al. [16] experimentally investigated the v/G window for defect-free Si growth, and determined a window of about 0.01 mm2min-1K-1.
Since the critical (v/G)0 determined by Hourai et al. is about 0.2 mm2min-1K-1, we assumed that the window of (v/G) / (v/G)0 for defect-free Si is ±0.025.
The hatched gray window in Fig. 5 is given by the evaluated critical stress (4.10 MPa) for defect-free crystal growth with parameter sets by Nakamura et al. in Fig. 4 [4,5].

Khöler et al. [4] show that the genetic variability of jute fibre is related to nature even jute.
Hearle et al. [10] show that the angle microfibrillaire characterizing the jute is influenced by the percentage of cellulose in the jute (61% to 71%).
The influence of the sequences of stacking on the mechanical properties (traction, inflection and of interlaminar shearing) of the untreated woven hybrid composites jute/polyester was studied in experiments by Sabeel et al. [31].

Yang et al. [1] studied the fluid flow inside of waved channel of the plan surface.
Lin Lin et al. [2] presented an improve design of wavy microchannel heat sink with changing the wavelength and/or amplitude along the flow direction.
Benzenine et al. [3] studied numerically the analysis of the turbulent flow of air in a 3D channel of rectangular section provided with two waved fins sequentially arranged in the top and the bottom of the channel walls.
Also, Laidoudi et al. [8] analyzed through numerical simulations the incompressible flow of Newtonian fluid inside a plan channel where there is the tandem of three circular cylinders.

Similar values are reported for sprayed CTS films by Adelifard et al [24].
These results are similar to the earlier report by Kahraman et al. [9].
These values are closer to the values (180-677 nm and 19 nm) reported by Reddy et al. [13].
These optical results are similar to the results earlier reported by Bouaziz et al. [7].

At accelerators, 22Na is produced by irradiation of Al or Mg targets with suitable projectiles such as protons, deuterons, or α particles.
In this experiment, a stack of thin Al foils was irradiated with 68 MeV protons provided by a cyclotron.
The activated Al foils can be used as positron emitters directly, without the necessity of chemical treatment.
The beam brightness is defined as B = I d2+θ2EL (2) with particle intensity (particles per second) I, the beam diameter d+, and the divergence θ = p ET/EL with transverse and longitudinal components of the positron energy ET and EL, respectively.
Polarized Positron Beam: A setup providing a spin-polarized positron beam was developed by Maekawa et al.[43] and is shown in Fig. 12.
