Hence, many countries have made the effort in establishing localized anthropometric databases for different population groups such as for civilian, military personnel, students and workers. ( Bolstad et al 2001, Wang et al 2002, MM Klarin et al., 2008, B.V.Shanasundara et al.,1999).

The magnetite itabirite (SIF.1) shows an enrichment in Al, Zn, Pb, Co and a depletion in Mg, Ti, V and Ni.
On the other hand, itabirite with megnetite (SIF. 2) reveals an enrichment in Mg, Ti, Zn, Cu and a depletion in Mn, Al, V, Ni and Co (fig. 45).
The chlorite (SIF. 8) and garnet-grunerite itabirites (SIF. 18) show an enrichment in Mg, Zn, Pb, but a depletion in Al, Ti, V, Ni and Co (Fig. 46).
During transport, the solution rich in iron (Fe), poor in aluminum (Al) and silicon (Si), under the effect of reduced atmospheric conditions or rich in CO2 causes the separation of iron (Fe) with silicon (Si) and aluminum (Al).

In our present work, attempt has been made to synthesize three types of CdS QTDs; one bare CdS (without doping and capping), another CdS@CH (stabilized with Chitosan without any doping) and a third one CdS;Cu (non stabilized with doping of copper) to explore their spectroscopic properties.We have synthesized CdS nanoparticles by modifying the method reported by Bhargava et .al [7, 8].

Higher strength TiAl alloys generally have only about 45at% Al since the fraction of Ti3Al,
the stronger phase, increases at low Al contents.
The resulting grain size in the cast ingots is in fact finer than in the high Al alloys and in the case of Ti44Al8Nb1B it is only 50µm.
The boride is TiB and not TiB2 in these low Al, more highly alloyed alloys.
This is especially true in the highly alloyed, low Al-content alloys where the borides are generally far larger.
It has been shown that pre-yield cracking in these stronger TiAl-based alloys reduces the fatigue limit from about 90% of the 0.2% proof stress characteristic of high Al alloys to about 60%, indicating that the fracture stress is not significantly increased by alloying or by reducing the Al-content [14].

Tallon et al. 5 used bond-valence-sum (BVS) method to calculate the hole concentration, P for Y123.
The relationship between the holes of Cu(2) and Tc has been widely accepted since Tallon et. el. discovered it in 1991 7.

Ortlepp et al. [9] proposed a model to calculate the ultimate bond force of double-lap-compression-tension tests.
Olivito et al. [16] studied the bond between flax and PBO FRCM on clay bricks using a double lap shear test varying the bonding length.
Finally, Bello et al. [17] studied how the coating of a vegetal fiber improves the mechanical properties of the composite.
The materials chosen were based on the studies performed by Mercedes et al. [19].

For instance Poesen [14] and Poesen et al [15] reported that stabilizing a bank gully head in Central Belgium with rock plug did not work in the loess-derived soils and an alternative techniques using geomembranes had to be developed.
Table II: Volumetric Estimates Of Soil Loss S/N Name of gully V (m3) El(tha-1yr-1) Ep (tm-2) V(m3)/a (m2) 1.
The values for AS2 obtained by Poesen et al [18] lies within the ranges 41 and 814m2 whereas that of Montgomery and Dietrich [19] gives ranges of 500 to 4000 (m2).
It will be noticed therefore that while the AS2 for Winners and Bebobsco lies within the ranges given by Poesen et al [18], that of Inyang Ansa (Etimbo) with AS2 = 17 lies outside these ranges, whereas that of Ikot Efangha Mkpa lies within the range of the AS2 values obtained by Montgomary and Dietrich [19].
Long term gully erosion rates EL in (tha-1yr-1) vary from 0.87 in Inyang Ansa Atimbo to a maximum of 8.30 at Ikot Efangha Mkpa.
