Oxygen delignified kraft pulp from eucalyptus (E. urophylla × E. grandis) was catalytically pretreated in aerobic condition using ammonium persulfate in present of catalists like cupric acetate and/or cobalt acetate in acetic acid-water solution, i. e. S2O82--Cu2+, S2O8...

     In a hydrothermal route devoted for synthesis of Ca10(PO4)6(OH)2 (HA) nanostructures, morphology can be controlled by experimental condition to form magical HA or nanostructured nanoparticles. In an intermediate condition, a novel nanostructure namely rose-like bundle of HA rod-likes was found, which is different from known HA nanostructures. The...

forest cover is one of the most effective factors in reducing flooding in northern iran, so that in recent years the destruction, land use changing and uncontrolled harvesting of forest areas, has greatly increased the number and magnitude of floods. so far, there have been few studies on forest hydrology in iran, particularly the northern hyrcanian forests. this study examines the impact of a ...

Block copolymer nano-micelles are especially important in cancer treatment because of their fine dimensions. In this article, three systems of amphiphilic copolymers with similar lengths and different ratios of the hydrophobic and hydrophilic chains are studied using implicit-solvent coarse-grained molecular dynamics simulations. The factor fphil is defined as the ratio of the number...

We propose an adaptive reversible data hiding method with superior visual quality and capacity in which an adaptive generalized difference expansion (AGDE) method is applied to an integer-to-integer subband transform (I2I-ST). I2I-ST performs the reversible subband transform and the AGDE method is a state-of-the-art method of reversible data hiding. The results of experiments we performed objec...

Inspired by the $P_{cs}(4459)$ reported LHCb collaboration recently, we investigate production from $\Xi_b$ decay in a molecular scenario using an effective Lagrangian approach. With different $J^P$ assignments to $P_{cs}(4459)$, magnitude of branching fractions $\Xi_b \to P_{cs}(4459) K$ is estimated, which order $10^{-4}$. Together with properties present estimations could be further testifie...
