The strain response of the sample, exemplified by Eq. (5) in the case of a linear system, includes the elastic component, related to the elastic strain of the lattice el ε and anelastic component anε .
Second, the concentration of point defects, accommodating for nonstoichiometry of the alloys increases with deviation from the stoichiometric composition both for Al-rich and Al-depleted alloys.
This feature is exemplified in Fig. 7 for Cu-Al and Cu-Al-Be alloys and reflects an unusual non-additive coupling of linear and non-linear damping components, when the Eq. (7) breaks.
Cu-Al-Ni alloys with γ'-martensite exhibit a twin relaxation peak as observed by K.

Kar et al[11] found an indirect gap of 0.9eV for ZrSe2 while a topological semi-metal character was identified in the case of ZrTe2.
Thus, from the optical transmission and absorption measurements over the energy range of 1-2.2 eV, Thalita et al found an indirect optical gap of about 1.78 eV for the ZrS2, while Liang et al [13] applied the Kramers-Kronig analysis to the energy loss data of ZrS2 and ZrSe2 for the electric vector E⊥c in the energy range of 0 to 50 eV and found peaks around 20eV for both materials.
Recently, Singh et al[16] have measured experimentally the dielectric function and refractive index of ZrS2 and ZrSe2 compounds via spectroscopic ellipsometry in the visible-to-NIR range.
Isomaki et al [20] performed calculations for ZrS2 and ZrSe2 using the SCSOPW method and found energy gaps of about 1.6 and 1.3 eV, respectively.

The dynamic fixation systems, so-called Dynesys, has been employed first by Stoll et al. but then formally introduced by Dubois et al. [31-36].

Swaine et al. [5] list As, Cd, Cr, Hg, Pb and Se as elements of greatest environmental concern; B, Cl, F, Mn, Mo, Ni, Be, Cu, P, Th, U, V, Zn of moderate concern; and Ba, Co, I, Ra, Sb, Sn and Tl of minor concern.
Elemental analysis of all samples was also performed by Elemental Analyzer (Vario EL Ⅲ) Department of coal and CBM engineering, Faculty of Earth Resources, China University of Geosciences.

Attending to the Romeiro Filho et al. [5] observation, for which "each company has its own culture and each project has its own characteristics", the proposed model is used to organize the processes of design, management and implementation of all diversity of R&D projects in the electricity sector, guiding teams and managers in an efficient and strong process directed to the guidelines of the R&D Program of Brazilian Electricity Sector process, although linked to the main processes of product development.

Yoon et al. reported their study on highly sensitive and selective Co3O4 nanofiber sensors [9].
Using Co3O4 nanorods, Patil et al. prepared a highly sensitive and fast responding carbon monoxide (CO) sensor, showing very high gas response of ca. 6.55 toward 50 ppm CO gas at 250 °C [17].
Park et al. synthesized Co3O4 hollow nanospheres using a hydrothermal synthesis method and fabricated sensors for volatile organic compounds (VOC) with a response of 6.3 to 1000 ppm ethanol vapor [18].
Surface elemental analysis was performed on an AXIS ULTRA X-ray photoelectron spectroscopy (XPS) instrument using monochromatic Al Kα X-ray source.

Such alloy is a solid solution hardened Al–Mg alloy, offering moderate strength, typically used in engineering structural applications such as pressure vessels, tanks, fitting, boat hulls, and van bodies.
As far as the s-e curves obtained on the welds are compared with that of the base alloy, it can be seen that the tensile strength of the joints is systematically lower than that of the BM-H111, according to the results obtained by Simoncini and Forcellese on similar and dissimilar FSWed joints in AA5754 and AZ31 sheets [10] and by Wonoh et al. on five different sheets in 6111-T4, 5083-H18, 5083-O aluminum alloys, dual-phase steel and AZ31 magnesium alloy [11].
behaviour can be explained by taking into account the effect of the rotational speed and welding speed on temperature, heat generation and cooling, as also shown by Leal at al. [12] and Nandan et al. [13].
