Seminar “Dynamics of Persistent Epidemic and Optimal Control of Vaccination”
This talk is devoted to a model of epidemic progression, taking into account vaccination and immunity waning. The proposed model consists of a system of delay differential equations with time delays determined by the disease duration and immunity loss.

Kazakh Agro Technical Research University named after S. Seifullin and Peoples' Friendship University of Russia invite you to participate in the International Scientific Conference “Food quality and food safety”, which will be held from September 20 to 22, 2023 in Astana (Republic of Kazakhstan).
Seminar: “Boundary regimes with peaking and large solutions of quasilinear parabolic equations”
There will be presented results on localized and non-localized boundary regimes with singular peaking in some finite time moment for general quasilinear parabolic equations.
Seminar “Modeling of the wave perturbation propagation in the heterogeneous environment using the grid-characteristic method”
This work is devoted to the development of numerical methods of higher order of accuracy and a software package for mathematical modeling of dynamic wave disturbances as applied to seismic, seismic exploration, geophysics, strength and nondestructive testing problems.
Scientific seminar “Supercomputer simulation of monatomic rarefied gas flows using parallel code “Nesvetay””
The presentations makes an overview of the current capabilities of the Nesvetay code as applied to monatomic rarefied gas flows based on the numerical solution of the kinetic equation with BGK and E.M. Shakhov (S-model) collision integrals. The “Nesvetay” code uses the author’s version of the discrete velocity method, which includes a finite volume scheme for approximating the transfer operator on arbitrary spatial grids, a conservative method for calculating macroparameters on an unstructured velocity grid, an implicit scheme for stationary problems, and an explicit method on moving deforming grids for modeling nonstationary currents.
Lecture “Metal-Organic Frameworks in Catalysis”
Coordination compounds that continuously extend in 1, 2 or 3 dimensions through coordination bonds are commonly designated as Coordination Polymers (CPs) or Metal-Organic Frameworks (MOFs), the latter showing an open framework containing potential voids.
Lecture “Selected Effects of Non-covalent Interactions in Coordination Chemistry”
Specific cases of hydrogen bonds will be highlighted, namely those assisted by resonance (RAHB) and by charge (CAHB), and how such contacts can be adjusted by the pH of the medium and temperature, influencing the generation of building blocks in supramolecular aggregates, the resolution of isomers, reactivity, etc.
Scientific seminar “Decomposition on the root vector series of the non-selfadjoint operators with the s-number asymptotics more subtle than one of the power type”
The first our aim is to clarify the results obtained by Lidskii V.B. devoted to the decomposition on the root vector system of a non-selfadjoint compact operator. We use a technique of the entire function theory and introduce a so-called Schatten-von Neumann class of the convergence exponent. Considering strictly accretive operators satisfying special conditions formulated in terms of the norm, we construct a sequence of contours of the power type on the contrary to the results by Lidskii V.B., where a sequence of contours of the exponential type was used. This approach allows us to obtain a decomposition on the root vector series of the non-selfadjoint operators with the s-number asymptotics more subtle than one of the power type.
