Let $K$ be a field of characteristic$p>0$, $K[[x]]$, the ring of formal power series over $ K$,$K((x))$, the quotient field of $ K[[x]]$, and $ K(x)$ the fieldof rational functions over $K$. We shall give somecharacterizations of an algebraic function $fin K((x))$ over $K$.Let $L$ be a field of characteristic zero. The power series $finL[[x]]$ is called differentially algebraic, if it satisfies...

Gold nanoparticles (AuNPs) offer a great promising in biomedical applications and their size has been shown to be important parameters that affect the particles uptake and cellular imbibition. The presented dielectric data indicates that AuNPs have well characteristic dispersion in the alpha relaxation region. The presented work aims to characterize and improve the quality control of AuNPs, def...

Six sigma is new to construction sector and this philosophy is to reduce the defects in the construction. The aim of this study is to evaluate Six Sigma as a process improvement method within construction sector. In order to improve the process in construction it is important to understand the factors affecting the construction process and analyze the factors for the construction improvement. I...
