Quasi exactly solvable matrix Schroedinger operators
Two families of quasi exactly solvable 2*2 matrix Schroedinger operators are
constructed. The first one is based on a polynomial matrix potential and
depends on three parameters. The second is a one-parameter generalisation of
the scalar Lame equation. The relationship between these operators and QES
Hamiltonians already considered in the literature is pointed out.Comment: LaTeX, 9 pp, new results adde

Quasi Exactly Solvable NxN-Matrix Schroedinger Operators
New examples of matrix quasi exactly solvable Schroedinger operators are
constructed. One of them constitutes a matrix generalization of the quasi
exactly solvable anharmonic oscillator, the corresponding invariant vector
space is constructed explicitely. Also investigated are matrix generalizations
of the Lame equation.Comment: 16 latex pages, new results adde
Methodical approach to conducting a comprehensive pharmacoeconomic study of drug care in medical organizations
The problem of rational pharmacotherapy in outpatient and inpatient therapy is one of the most significant to date, due to the occurrence and progression of most pathologie
Improving the competitiveness of pharmacies by means of informational technologies
The article presents the results of sociological research of the consumers of pharmaceutical services and the structure of the main reasons of the consumers’ visiting the pharmacies. The aspects of the informational activity of the pharmacists have been analyzed. The approach to the improvement of a pharmacy’s competitiveness by means of informational technologies that is the touch information terminals placed in trade area has been worked out. The unique pharmaceutical informational basis for the customers of the pharmacies and the software for the touch information terminals have been worked outyesBelgorod State National Research Universit
Quasi exactly solvable operators and Lie superalgebras
Linear operators preserving the direct sum of polynomial rings P(m)\oplus
P(n) are constructed. In the case |m-n|=1 they correspond to atypical
representations of the superalgebra osp(2,2). For |m-n|=2 the generic, finite
dimensional representations of the superalgebra q(2) are recovered. An example
of a Hamiltonian possessing such a hidden algebra is analyzed.Comment: 8 Revtex pages, 1 PS-figures; Section IV extended, reference adde
Problem of working out the objective and subjective fundamentals of pharmacy
We have shown the necessity of substantiation of the status of pharmacy as an independent science and theoretical comprehension of pharmacy as a system of scientific knowledge. Pharmacy should find the principles of theoretic unity of its knowledge in the specifics of pharmaceutical activity. We have carried out gnoseological analysis of the sphere of interests of chemistry, medicine, toxicology and pharmacy in the field of studying the drugs. Pharmaceutical aspects of a drug as an object of pharmaceutical activity have been shown. We have studied the regularities between the structure of a drug and the range of its biological activity in order to work out the methods of its analysis and synthesisyesBelgorod State National Research Universit
