The adsorption studies of phenol from aqueous solution on allium sativum peel have been studied in the range of 50-250 mg/L initial phenol concentration .The study was carried out as function of contact time, pH, initial phenol concentration,allium sativum Linn peel dosage and temperature. The experiment demonstrated the maximum phenol was obtained at in pH of 2 and it takes 6h to attain equili...

The algorithms will be described using a pseudo-code that will be a mixture of English sentences and of constructs akin to those of C and Pascal. Though pseudo-code is a very informal way of describing an algorithm, it can be used so that the description is unambiguous and also so that it is apparent what is the number of elementary steps that are executed by a given algorithm on a given input....

Abstract Consider a directed tree $${\mathcal {U}}$$ U and the space of all finite walks on it endowed with quasi-pseudo-metric—the strategies {S}}$$ S graph,—which represent possible changes in evolution dynamical system over time. reward function acting subset {S}}_0 \subset {\mathcal <mml:...

In this paper, we consider the equilibrium problem for a pseudo-monotone function. For solving this problem, a hybrid ergodic-splitting method is proposed. We decompose the equilibrium function into two functions and then solve auxiliary problems for each decomposition function separately. Under pseudo-monotonicity of the equilibrium function and some additional assumptions, we prove that the s...

Statistical inference for discrete time observations of an affine stochastic delay differential equation is considered. The main focus is on maximum pseudolikelihood estimators, which are easy to calculate in practice. Also a more general class of prediction-based estimating functions is investigated. In particular, the optimal prediction-based estimating function and the asymptotic properties ...

We shall consider generated pseudo-operations of the following form: x⊕ y = g(−1) (g(x) + g(y)) , x ̄ y = g(−1) (g(x)g(y)) , where g is a positive strictly monotone generating function and g(−1) is its pseudo-inverse. Using this type of pseudo-operations, the Riemann-Stieltjes type integral will be introduced and investigated.

A “strong” cryptographic hash function suitable for practical applications should simultaneously satisfy many security properties, like pseudo-randomness, collision resistance and unforgeability. This paper shows how to combine two hash function families each satisfying different security property into one hash function family, which satisfies both properties. In particular, given two hash func...

adsorption capacity of 4-chloro-2-nitrophenol (4c2np) onto nano-ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-tio2 dosage, initial ph and initial 4c2np concentration. optimum conditions for 4c2np adsorptionwere found to be initial ph z 2, nano-tio2 closer- 0.01 g and equilibrium time 1 h. the adsorptionkine...

biosorption of acidic dyes using the live fern azolla filliculoides was studied in a discontinuous system. dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?c and ph=7. it was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. also, type of dye has an ...
