Energy concentration of gain (EG) is an inherent component in beef cattle feeding systems. The National Research Council (NRC) uses equations based on body weight, rate of gain and cattle type to predict EG and, in turn, to calculate dietary energy requirements. From EG, fat and protein deposition can be calculated directly. A dynamic computer growth model also can be used to estimate EG. In bo...

High-aspect-ratio TiO(2) nanotube arrays formed by anodic oxidation have drawn extensive attention due to their easy fabrication and various excellent optical, electrical and biomedical properties. In contrast to conventional single-layer TiO(2) nanotubes prepared via constant-voltage anodization, we synthesize multilayer TiO(2) nanotube arrays with high surface area by using alternating-voltag...

To probe the influence of structural variation within dibenzo-16crown-5-oxyacetic acids upon the selectivity of alkali metal cation separations by solvent extraction and liquid membrane transport processes, studies have now been conducted in homogeneous solution by NMR spectroscopy and titration calorimetry and in the solid state. Condensation polymerization of such proton-ionizable lariat ethe...

an enzyme electrode was developed using the enzyme sulfite oxidase (ec1.8.3.1) immobilized onto pig intestine. hydrogen peroxide produced was monitored amperometrically. all experimental parameters such as ph, temperature, buffer constituent concentration, were thoroughly investigated and optimized when appropriate. the response to sulfite concentration was linear in the range 5.2´10-6 to 1.02´...

fluids for various industrial applications because of their excellent thermal performance. this study analytically and experimentally examines the effects of nanoparticle dispersion on the entropy generation of eg–al2o3 nanofluid flows through a helical pipe as a heat exchanger under constant wall heat flux thermal boundary condition in laminar regime. it is found that adding nanoparticles impr...

Due to emergence of serious obstacles by scaling of the transistors dimensions, it has been obviously proved that silicon technology should be replaced by a new one having a high ability to overcome the barriers of scaling to nanometer regime. Among various candidates, carbon nanotube (CNT) field effect transistors are introduced as the most promising devices for substituting the silicon-based ...

We consider extremal graph-theoretic problems on regular structures. The problems ask to maximize a certain parameter of the structures in question under the condition that the values of some other parameter(s) are constant. This is where the term isoparametric is taken from. The graph problems we consider are edge-isoperimetric problems, and the poset problems are dealing with the notion of Ma...

Let $R$ be a commutative ring with nonzero identity and let $M$ unitary $R$-module. The essential graph of $M$, denoted by $EG(M)$ is simple undirected whose vertex set $Z(M)\setminus {\rm Ann}_R(M)$ two distinct vertices $x$ $y$ are adjacent if only ${\rm Ann}_{M}(xy)$ an submodule $M$. $r({\rm Ann}_R(M))\not={\rm Ann}_R(M)$. It shown that connected diam}(EG(M))\leq 2$. Whenever Noetherian, it...
