The samples were collected as Li et al. [8].
Staudt et al. [13] revealed large seasonal changes in both the quantity and composition of the monoterpene emissions from Pinus pinea.
Holzko et al. [22] suggested that a twofold intraspecific variation was important relative to long-term effects of light.

McKenna et al. [9] formulate this more precisely.
By calculating the integral of the quantities, the indicators compare energy amounts similar to the indicators that McKenna et al. defined.

Finally, the degree of autonomy by McKenna et al. reduced, since the storage system basically causes a smoothing of the residual load.

Pre-aging and Maturing Effects on the Precipitation Hardening of an Al-Mg-Si Alloy T.
Hamamda a (a) Laboratory of Themodynamic and treatment of surface of Materials, Physics Institue Mentouri University, Road Ain -El Bey, Constantine, 25000, Algeria abidtah@yahoo.fr Keywords: Al-Mg-Si Alloy, DSC, Reaction kinetic, Activation energy, Precipitation hardening Abstract.
Experimental procedure The examined material is an Al-Mg-Si alloy with excess of silicon.
This effect has been already observed by Marioara et al. [10].
This result is in agreement with the work undertaken by Miao et al. [3].

Determinations of Total phenolic content (TPC) The total phenolic contents of crude extracts were determined with Folin–Ciocalteu reagent, according to the method of Luo et al. [7].
ABTS assay The method, based on the ability of antioxidant molecules to quench the long-lived ABTS radical cation (ABTS•+), of Re et al [9] was modified.

El-Hawary et al. (1997) [1] presented test results of 8 RC beams which the effect of fire exposure time and the concrete cover thickness on the behavior of RC beams subjected to fire in shear zone and cooled by water is investigated.
Shang shouping et al. (2009) [3] reported shear strength experiments of 8 simple beams which the fire resistance of the RC beams strengthened with U-type high performance ferrocement laminate layer or without is analyzed.
