Coagulation in lipid- and protein-containing systems

The behavior of real disperse systems with organic impurities was examined under conditions of destabilization by inorganic coagulants. A number of physicochemical methods of analysis and a simulation method were used to identify the character and type of the complexes formed and to calculate their stability constants.     

Interaction of Pd(II) with Glutamic Acid

Pd(II) complexes with glutamic acid of the composition K[Pd(HGlu)Cl₂] (I) and [Pd(HGlu)₂] (II) were synthesized and studied by IR and electronic absorption spectroscopy methods. Pd²⁺–H₂O–Cl^– and Pd²⁺–H₂O–Cl^––H₂Glu systems were analyzed by pH-metric titration. The most essential Pd(II) complex forms were established by mathematical modeling and their formation constants were calculated. The electronic absorption spectra of complexes I and II were measured in aqueous and physiological solutions. Complex I was found to be biologically active and to exhibit antimetastatic properties.     

Complexation of ferric ions with glucosamine

Conclusion Mathematical modelling was used to show the formation of mono and dihydro complexes with glucosamine and the H₂Gl²⁺ form in physiological solution. The formation constants of these species were calculated.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 937–939, April, 1987.     

Single and multiple muons and the generation of neutrons in the LVD experiment

The large geometric factor and good spatial resolution of the Large Volume Detector (LVD) ensures statistically significant and highly accurate measurements of muon trajectories and determination of the multiplicity of muon groups. The developed algorithm allows us to reconstruct 2 × 10⁶ muon events (single muons and muon groups). Characteristics of muon groups are obtained and the specific yield of neutrons produced by single muons, muon groups, and showers is determined.

On parabolic subgroups in Coxeter groups of large type

In this paper, properties of the elements of parabolic subgroups in Coxeter groups of large type are considered.     

Coagulation and Flocculation Purification of Fat- and Protein-Containing Disperse Systems

Procedure for treatment of wastewater with a coagulant (aluminum sulfate) and anionic flocculants to remove fats and proteins was studied The purification efficiency was evaluated from the flocculation parameters.
