The root is an important plant part contributing to peanut productivity underwater-limited conditions. Root volume, root surface area and root diameter may becharacters responding to pre-flowering drought (PFD) in peanut. The objectives ofthis study were to investigate the responses to PFD for root surface area, rootvolume and root diameter and to determine the inter-relationships among theresp...

One of the challenges in the printing industry is the presence of extra lines in printing design. This problem is due to the improper surface roughness of carved cylinders. This research endeavors to specify and optimize the effective parameters on the surface roughness of chrome coated printing cylinders in the finishing process that is done using a finish star machine. Investigated parameters...

Objective(s): Response surface methodology (RSM) by central composite design (CCD) was applied to statistically optimize the preparation of Rutin-Quercetin (Ru-Qr) dual drug loaded human hair keratin nanoparticles as well as evaluate the characteristics. Materials and Methods: The effects of three independent parameters, namely, temperature (X1:10-40 C), surfactant (X2: SDS (1), SLS (2), Tween-...

In this work, three types of natural clays including kaolinite, montmorillonite, and illite with different molecular structures, as adsorbents, are selected for the removal of methylene blue dye, and their performance is investigated. Also the optimization and the analysis of the dye adsorption mechanism are performed using the response surface methodology, molecular modeling, and experimental ...

A problem facing the product development community is developing simultaneous solutions of response variables (to several properties) that depends on a number independent or sets responses. Harrington, among others, addressed this and presented desirability function with functional approach. Derringer Suich altered their approach illustrated how multiple can be transformed into convenience func...
