A New Two-Component Model for Hadron Production in Heavy-Ion Collisions by Xuejiao Yin, LiLin Zhu, Hua Zheng

“…Using the experimental data from the ALICE program on the centrality dependence of the transverse momentum (pT) spectra in Pb+Pb collisions at sNN=2.76 TeV, we show that the double-Tsallis distribution and the generalized Fokker-Planck (FP) solution cannot describe the spectra of pions, kaons, and protons from central to peripheral collisions in the entire pT region, simultaneously. …”

Preliminary results on the transverse flow of charged K mesons emitted from Ag+Ag collisions at beam energy of 1.58 GeV/nucleon measured with HADES by Orlinski Jan

“…The K± flow is compared to the corresponding distributions for protons emitted from the same system. These comparisons suggest a repulsive potential between the K+ and nuclear matter, while conclusions for the K− are not possible to be drawn at this point, due to high statistical uncertainties.…”

Peculiarities of the Adsorption of Heavy-Metal Ions from Aqueous Media by Modified Cellulose by Tatiana E. Nikiforova, Vladimir A. Kozlov, Vera A. Loginova

“…It is established that a-hydroxycarboxyl groups, which are present in all three kinds of sorbents, form colourless chelate complexes due to the replacement of their protons with an equivalent amount of metal ions. Because of the charge transfer during metal–ligand interactions, coloured chelate complexes are formed. …”

Influence of Framework Silica to Alumina Ratio on the Sorption Characteristics of Synthetic Large-Port Mordenites by A.A. Shaikh, P.N. Joshi, H.S. Soni, V.P. Shiralkar

“…Sorption uptake using different probe molecules such as water, benzene, n-hexane and cyclohexane was measured on the protonic form of the mordenite samples. The sorption energetics in large-port mordenites as a function of framework SiO 2 /Al 2 O 3 ratio was discussed on the basis of the isotherms for water sorption over the temperature range 303–403 K. …”

From DNA Radiation Damage to Cell Death: Theoretical Approaches by Francesca Ballarini

“…Furthermore, a mechanistic model developed at the University of Pavia and based on the relationship between cell inactivation and chromosome aberrations was presented, together with recent results; the good agreement between model predictions and literature experimental data on different radiation types (photons, protons, alpha particles, and Carbon ions) supported the idea that asymmetric chromosome aberrations like dicentrics and rings play a fundamental role for cell death. …”
