As expected, ratio of atomic aluminum to nitrogen (Al/N) decreases with increase in N2 proportion in the gas mixture.
Decreasing N2 proportion, lower than 20%, may result in unreacted Al in Al flux and affect the composition.
In contract, when N2 proportion exceeds 20%, Al flux would completely react and N ions remain in films as defects.
Fig. 1 shows the Al/N ratio decreases as increase in N2 proportion, while preferred orientation has the opposite trend.

The preparation process include following stages: (i) producing Cu-0.5%Al pre-alloyed powder by water atomization method; (ii) Oxidation of atomized Cu-Al alloy powder at approximately 900 ͦ C for 1 hour in the air; (iii) Reduction in hydrogen atmosphere at 800 ͦ C for 1 hour; (iv) Pre compacting of powder at 500Mpa in a copper can; and (v) Extruding of pre-compacted sample at 900 ͦ C in an argon atmosphere to a rod with 17 mm diameter followed by drawing to get a high density of dislocations.Tensile properties at ambient and elevated temperatures were determined in according to the standard test methods (ASTM E8M).

The perfusion with the contrast agent (Microfil® MV-122, Flow Tech, Carver, MA, USA) was performed as described by Kampschulte et al [10], followed by removal of both thighs including the femora.
The sections were measured semiautomatically using a light microscope (BX63; Olympus, Hamburg, Germany) in combination with a digital camera (DP73, Olympus, Hamburg, Deutschland) and cellSens TM software; semi-quantitative analysis of the immunohistochemically stained sections was performed as described previously (Knabe et al. 2006) [11].
The increase of blood vessel diameter of the RP, cells & AVB group was in accordance with findings by Polykandriotis et al. [13], who observed an increase in diameter of blood vessels after 2 months, which accommodated increased perfusion from arterioles, precapillary arterioles, capillaries and postcapillary venules to draining venules and veins.

Although the majority of surviving casonas in Lima have only two storeys, Hotel El Comercio represents an upper limit of the typology and hence its response will be particularly significant.
Consequently, the geometry of the quincha frame and its connections often vary throughout the building, which is very much the case in Hotel El Comercio.

Abdallah et al. [9] presented the fiber-matrix interfacial properties of hooked end steel fibers embedded in UHPFRC matrixes with various water/binder ratios, the results showed that the total pullout work was more prominent for the fiber with a larger diameter and a longer embedded length.
