The tassel fern, Huperzia squarrosa, is a rare and medicinally valuable plant known for containing Huperzine A. It propagates naturally through spores, rhizomes, cuttings, and clump division, but with a slow multiplication rate. This study aimed to optimize propagation conditions for H. squarrosa using stem cuttings and in vitro culture techniques to support its preservation and development.

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.
