Key words: MAntibacterial assay, eco-friendly, nanoparticles, silver nanoparticles, zone of inhibition Reference  Kim, S. The standard Arrehenious equation of 0.3% carbon steel is utilized to obtain an optimal deformation path such that the percentage of volume fraction recrystallization should be 1.

The presence of zone of inhibition clearly indicated the antibacterial activity of silver nanoparticles. The values for modulus of rupture and thermal conductivity averaged 81 MN/m2 and 0.494 W/mo K. The refractoriness of all the samples were 1300o C and this showed that they could be used as insulating materials.

After obtaining the Va R and ETL estimates we proceed to evaluate the statistical significance of the differences in performance of the analysed risk models.
The values for specific gravity, bulk density, solid density and apparent porosity averaged 2.75, 2.04 g/cm3 , 3.18 g/cm3 , and 13% respectively and they were within the internationally accepted range.
The values for linear shrinkage, permeability to air and thermal shock averaged 8.57% 69.4, and 29 respectively and these also were within the accepted limits.
The results showed that the linear shrinkage improved from an average of 8.57% for the three samples for 0% sawdust to an average of 8.32% with 40% addition of saw dust, bringing them closer to the lower range of the international standard of 7-10%. In the other approach PID controller is employed for the plant model (microstructure development).

Ltd, New Delh Abstract: l Capital of Abuja like linear shrinkage, solid density, apparent porosity and thermal conductivity were characterized with a view of studying the effect of sawdust on them. The state-space model together with an optimality criterion is used to control the percentage of volume fraction recrystallization using Linear Quadratic Regulator method.
