Climatic Data.
The field data was observed through the usage of weather Tracker Kestrel 4500 model for Temperature and Relative Humidity.
Also, secondary data was obtained from Nigerian Meteorological Agency (NIMET) to benchmark the field data.
Over the period, there have been reductions in the bacterial abundance with mean value from the baseline samples (16 133 333 Cfu/g) higher than that of the current soil samples (46 333 330 Cfu/g).
The obtained and generated data in this study (plant capacity, pollution parameters on soil and water) can be used to model optimum engine stack with minimal pollution level. 2.

This mechanism is probably for a part responsible of the radiation induced reduction observed of many oxides [28].
In oxides a fairly large amount of data is available on i) stimulated annealing of radiation damage in oxides under inelastic losses, in Al2O3 and MgO for example under proton irradiation [37], ii) radiation enhanced metallic colloids formation, in electron irradiated MgO containing iron or nickel [38] iii) ionization preventing amorphization under highenergy heavy ion irradiation [39], iv) concurrent electron and heavy ion irradiations lowering the nucleation rate of dislocation loops but enhancing the growth, in the Al2O3/MgO system [40].
The simple theory above predicts a reduction of the activation energy by a factor of two with respect to the sole migration term of the slowest defect, which here is expected to be of the order of 3.7eV [66].
This effect is generally thought to be due to the non silica part of the glass and associated with metal-oxygen bond breaking and reduction of metal ions; the metallic ions and the oxygen, atomic and/or molecular, are supposed to migrate easily in the remaining glass and cluster.

Rietveld refinement is performed using International Center for Diffraction Data (ICDD) for structural characterization.
The parameters obtained via curve fitting of the XRD data of the sample and the reference Bi.
The function used to fit the experimental data is given in Eq. 1.
These data are a consequence of the used chemical synthesis technique to synthesize high quality bismuth nano/microparticles.
Strain is calculated using XRD data for (012) peak and found to be 4.156×10-4.

Some ways of functionalization by ionizing radiation are grafting, crosslinking and stabilization, surface modification by functional groups, doping and GO reduction [25], [29].
Though the synthesis of composites has been carried out and the composites are used, the present literature lacks the data on amount of grafting, a detailed study on the effect of polymerization conditions on the grafting percentage ̶ in fact how important it is to carry out the graft polymerization at certain reaction conditions, and the resulting application specific properties due to grafted amount of polymer.

The obtained results were compared with experimental data.
An increased Casson parameter results to a reduction in velocity component and an increase in temperature distribution as well concentration profile in the presence or absence of the magnetic field.
Increasing Forchhiemer parameter (Fs), results to a reduction in the velocity profile, whereas both temperature and nanoparticle distribution are increased.

The experimental data validated the simulation results and showed that the temperature change and distribution area in the process were related to the exposure structure.
From the fig.6, it can be seen that the change of the internal shape (reduction of the reaction area) can effectively accelerate the thermal diffusion and reduce the central heat accumulation.

Systematic analysis of many experimental data led to question chemical, physical, mechanical parameters contributing significantly to improve the kinetics of absorption/desorption.
All these techniques are known to create high densities of defects parallel to a dramatic reduction of the crystallite mean size as shown on Fig. 2 b (left).

We provide a simple theoretical explanation why these materials can exceed the hardness of diamond, and outline a possible way how to design new nanocomposites with even higher hardness when reduction of Friedel oscillations of the valence charge density, which weaken the strength of the transition metal nitride, can be accomplished.
The somewhat lower value for c-BN from Ref. [13] should emphasize that there is some scattering of the data due to different quality of the samples.
Moreover, we have shown recently, that upon shear to a strain of about 0.5, ReB2 undergoes electronic instability with the formation of strongly bonded B2-like dimers which weakens the Re-B bonds [38], and upon further 0 100 200 300 400 500 600 0 20 40 60 80 100 120 c- & w- BN nanocomposites c-BN - Dubrovinskaia Vickers Hardness (GPa) Elastic Moduli (GPa) CB2N BC5 c-BN - Teter Diamond nc-TMN/a-Si3N4 Nanocomposites Fig. 1: (colour online) Correlation of hardness and shear moduli of conventional materials which deform by crystal plasticity: solid circles are from [12], the data for CB2N, BC5, "c-BN-Dubrovinskaia", "c- & w-BN nanocomposites" and for the nc-TMN/a-Si3N4 nanocomposites are from papers quoted in text.

The replacement of NA with SSA has increased density, stability and flow values and reduction in air voids for the HMA specimens cast and tested.
A matured co-precipitation method was used for improving the Fe3O4 content on the surface of steel slag, for the comparison of the data obtained in a numerical model, to satisfy the performance requirements of the pavement engineering.
