We consider the Quartic Horndeski theory with torsion on a Friedmann-Lema\^{\i}tre-Robertson-Walker background in second-order formalism. show that there is one parameter family of Cartan Lagrangians and all such theories only modify dispersion relations graviton scalar perturbation are usually found standard torsionless spacetime. In other words, for this class, does not induce new degrees fre...

The fractal degree of adsorption on the multi-walled carbon nanotube has been investigated. The fractal-like Langmuir kinetics model has been used to obtain the fractal degree of ion adsorption on multi-walled carbon nanotube. The behavior of the fractal-like kinetics equation was compared with some famous rate equations like Langmuir, pseudo-first-order and pseudo-second-order equations. It is...

The Biosorption property of S. cerevisiae for chromium uptake was investigated in an immobilized cell bioreactor. Saw dust was utilized as the solid bed in the reactor. Adsorption of S. cerevisiae on saw dust obeys a first order reaction kinetic up to 6 hours. The immobilized biomass particles are porous and exist in the new generation of biological adsorbent. Chromium biosorption was studied i...

In this work, the causality and stability of a first-order relativistic dissipative hydrodynamic theory, that redefines fields from first principle microscopic estimation, have been analyzed. A generic approach gradient expansion for solving transport equation has adopted using Chapman-Enskog iterative method. Next, momentum dependent relaxation time approximation (MDRTA) employed to quantify c...

The purpose of this work was to study the effect of initial pH and yeast Saccharomyces Cerevisiae on biogas production from tofu wastewater (TW). The initial pH was varied in ranging of 5 – 9 in substrate without yeast (T5-T9) and with yeast (TY5-TY9). The results showed that optimum initial pH was 8. The maximum biogas was resulted in T8 (275 mL) and TY8 (421 mL). Yeast addition increased tota...

The adsorption of human serum albumin onto hydroxyapatite-modified silver electrodes has been in situ investigated by utilizing the piezoelectric quartz crystal impedance technique. The changes of equivalent circuit parameters were used to interpret the adsorption process. A kinetic model of two consecutive steps was derived to describe the process and compared with a first-order kinetic model ...
