Adsorbents functionalized with polyol are considered to be effective for the removal of boron from aqueous solutions. In this work, polyol-functionalized chitosan particles were successfully synthesized. Batch experiments were conducted for the determination of the optimal conditions for the highest degree of gluconated groups being grafted to chitosan substrate.

I. Introduction An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.

The catalyst 7.5% NiO/TiO2 and seven samples of NiO/γ-Al2O3 with NiO content from 7.5% to 60% have been obtained and studied. Physico-chemical characteristics of the catalysts were determined by methods of Adsorption (BET), X-ray Diffraction (XRD), TemperatureProgrammed Reduction (TPR) and Hydrogen Pulse Titration. The catalytic properties of the obtained samples were investigated in the reaction of CO methanation at temperatures 180 – 220◦C and mole ratios hydrogen/carbon monoxide 25-100.

(BQ) In this paper, working current, working voltage, oil pressure, spark gap Pulse On Time and Pulse Off Time on Material Removal Rate (MRR) and Surface Finish (Ra) has been studied. Empirical models for MRR and Ra have been developed by conducting a designed experiment based on the Grey Relational Analysis. Genetic Algorithm (GA) based multi-objective optimization for maximization of MRR and minimization of Ra has been done by using the developed empirical models. Optimization results have been used for identifying the machining conditions.

Acomputational approach is used to analyse temporal gene expression in the context of metabolic regulation. It is based on the assumption that cells developed optimal adaptation strategies to changing environmental conditions. Time-dependent enzyme profiles are calculatedwhichoptimize the function of a metabolic pathway under the constraint of limited total enzymeamount.For linearmodel pathways it is shown thatwave-like enzyme profiles are optimal for a rapid substrate turnover.

Amathematicalmodel hasbeendevelopedtostudy theeffect of external tryptophan on the trp operon. The model accounts for the effect of feedback repression by tryptophan through the Hill equation. We demonstrate that the trp operonmaintains an intracellular steady-state concentration in a fivefold range irrespective of extracellular conditions. Dynamic behavior of thetrp operon corresponding to varying levels of extracellular tryptophan illustrates the adaptive nature of regulation.
