NiMn2O4 nanoparticles have been successfully prepared through sol-gel method. The effects of different factors such as the type of solvent, and amino acid temperature were investigated on the size and morphologies of products. The smallest particle size of NiMn2O4 nanoparticles was found to be 25 nm in diameter. The magnetic properties of the samples were also measured by an alternating gradien...

We describe tensor product type techniques to derive robust solvers for anisotropic elliptic model problems on rectangular domains in R d. Our analysis is based on the theory of additive subspace correction methods and applies to nite-element-and prewavelet-schemes. We present multilevel-and prewavelet-based methods that are robust for anisotropic diiusion operators with additional Helmholtz te...

pyrolysis of low density polyethylene (ldpe) by equilibrium fluid catalytic cracking (fcc) was studied in a stirred reactor under different process parameters. in this work, the effect of process parameters such as degradation temperature (420-510°c), catalyst/polymer ratio (0-60%), carrier gas type (h2, n2, ethylene, propylene, ar and he), residence time and agitator speed (0-300 rpm) on the c...

Objective(s) Staphylococcus aureus is both a successful human commensal and a major pathogen. In this study we investigated the genetic diversity of 26 S. aureus isolates recovered from human skin and urinary tract infections. Materials and Methods Typing procedure for the studied S. aureus isolates was performed based on PCR amplification of the aroA gene, which encodes the enzyme 5-enolpyr...

We describe a general framework to define dendriform algebras and a general construction to obtain new dendriform algebra structures from known structures and from linear operators. The construction includes recent constructions of the quadri-algebra, the ennea-algebras, the dendriformNijenhuis algebras and the octo-algebras.
