This paper introduces an implicit scheme for a   continuous representation of nonexpansive mappings on a closed convex subset of a Hilbert space with respect to a   sequence of invariant means defined on an appropriate space of bounded, continuous real valued functions of the semigroup.   The main result is to    prove the strong convergence of the proposed implicit scheme to the unique solutio...

In this research, mechanical buckling of rectangular plates of functionally graded materials (FGMs) is considered. Equilibrium and stability equations of a FGM rectangular plate under uniform in-plane compression are derived. For isotropic materials, convergent buckling loads have been presented for non-uniformly compressed rectangular plates based on a rigorous superposition fourier solution f...

Ammonia-nitrogen uptake by seaweed was modeled based on the concept of ammonia-nitrogen permeation through cell membrane, and the derived model of uptake rate was experimentally verified. In this study, sterile Ulva sp. was employed as seaweed to treat model culture solution, and the distribution equilibrium of the ammonia-nitrogen between the culture solution and cell inside was measured to ob...

This study concerns the performance of cocoons spun by silk worms as a natural ‎adsorbent for removal of Methylene Blue (MB) from aqueous solutions. To study the adsorption ‎process, the effect of various parameters such as contact time, adsorbent dosage, dye initial ‎concentration, and pH of the solution were investigated. According to the experiments, the kinetic ‎data were best described by ...

zinc ions are present in different types of industrial effluents, being responsible for environmental pollution. biosorption is a process in which solids of natural origin are employed for binding heavy metals. it is a promising alternative method to treat heavy metal wastes mainly because of high metal binding capacity. the effect of some important parameters on sorption capacity of cyanobacte...

we consider the bifurcation of periodic solutions from an equilibrium point of the given equation: x =f(x,?) , where x ? r , ? is a vector of real parameters ? , ? , ... , ? and f:r x r ->r has at least second continuous derivations in variables

The identification of large numbers of biologically active chemical entities during high throughput screening (HTS) necessitates the incorporation of new strategies to identify compounds with drug-like properties early during the lead prioritization and development processes. One of the major steps in lead prioritization is an assessment of compound binding to plasma proteins, because it affect...

In the present study seven synthetic polymers were used as adsorbents for the removal of Cd(II) from aqueous solution. The equilibrium studies were systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. The analyzing system was an atomic absorption spectrometer (Perkin-Analyst 100). It was...

Today, the equilibrium behavior of ions in solution may be predicted with some confidence, essentially because rapid ionic diffusion over small distances ensures homogeneity throughout the solution. Equilibrium concepts such as ionic strength and pH apply. However, when attempting to understand the behavior of ions passing rapidly through narrow pores such as ion channels, no such equilibrium s...
