A new formulation for shape and topology optimization in a Stokes flow is introduced. The investigated problem minimizes the total potential power of the flow. By combining a porous medium and a phase field approach we obtain a well-posed problem in a diffuse interface setting that can be reformulated into a problem without state equations. We can derive a sharp interface problem with zero perm...

Urate oxidase is a peroxisomal enzyme with four equal subunits that convert uric acid to allantoin, more soluble metabolite for excretion. The usage of uricase as drug in medicine treat hyperuricemia. Many microorganisms have been used production such Streptomyces exfoliates, Pseudomonas aeruginosa, and Aspergillus flavus. In this study, soil samples were collected then cultured screening mediu...

This study focuses on the examination of effect cutting parameters surface roughness when drilling medium-density fiberboard (MDF) with a parallel robot. Taguchi technique was applied to find optimum and, later, processing. Experimental layout established using L18 orthogonal array, and experimental data were examined via statistical analysis variance (ANOVA). results performed by multiple regr...
