Hyperon production in pp collisions

We report on a study of the proton induced hyperon production reactions. We discuss the theoretical efforts made towards understanding the existing data and the uncertainties involved in the calculations. Our recent calculations of the missing mass spectra for the pp → K ⁺ Λp reaction which involve a proper coupled channel treatment of the final state Λp interaction are presented. Significant differences in the results using different models of the hyperon-nucleon interaction are found.     

Modification of cellulose in the solution of methanesulfonic acid

Heat Resistance of copolymers of alkyl methacrylates with <Emphasis Type="Italic">o</Emphasis>-allylphenol

The heat resistance of copolymers of alkyl methacrylates with o-allylphenol was studied. The possibility of preparing viscosity additives that would be more resistant to heat than alkyl methacrylate homopolymers was examined.     

UV-Sensitive Porous ZnO-Based Nanocrystalline Films

Crystallography Reports - Nanocrystalline porous ZnO films have been synthesized by thermal oxidation of amorphous zinc deposits with an anomalously developed surface, which were previously formed...     

Synthesis of graft copolymers based on 1-hexene oligomers and their trials as viscosity additives

Copolymers of decyl methacrylate with 1-hexene were prepared and tested as viscosity additives to petroleum oils. The influence of the concentration of the synthesized copolymers on the viscosity-temperature characteristics of petroleum oils was examined, and the thermal and mechanical stability of the copolymers in oils was evaluated.
