Thank you for being a part of our specialty section. Our specialty section had an overwhelming response at 2016 SOT Annual Meeting in New Orleans and we were thrilled by the input we received from the participants. I hope you are looking forward to this year’s meeting in Baltimore in March. Our members have organized some great sessions for you all. I strongly encourage all the members to take advantage of these annual meeting as they serve as great professional networking venues and platforms for scientific leadership. This year, in addition to two graduate student travel awards, the CVSS also will be awarding the prestigious Roger O. McClellan Student Endowment Award. This award is designed to encourage veterinarians to become involved in a toxicology career. CVSS encourages all interested veterinary graduate students to apply for this award in 2018.

The paper is devoted to the numerical modeling of the blood flow in the human cardiovascular system with allowance for gravitational action. A model of the operation of the heart and an equation of state are proposed and studied. Modifications of the graph of the cardiovascular system for the simulation of possible positions of the object in conditions of multifold gravitational overloads are considered.

We suggest an original scheme and an algorithm for the numerical solution of the Euler equations of gas dynamics. The construction of the scheme is based on the mass, momentum, and energy conservation laws. The flux computation is carried out by summation of elementary fluxes formed by small-amplitude running waves that satisfy the linearized equations of gas dynamics. The scheme contains no artificial regularizers, has second-order accuracy on smooth solutions, and is quasimonotone in a neighborhood of the discontinuities. Examples of one- and two-dimensional computations are given.

The present paper deals with the numerical simulation of the propagation of pulses of blood pressure and velocity in a blood vessel. The numerical solution of the system of linear hemodynamic equations is formed as a superposition of progressing waves (Riemann invariants) satisfying the transport equations. Considerable attention is paid to the construction of a difference scheme for the linear and quasilinear transport equations. Examples of computations are presented. The suggested algorithm can be generalized to the case of a quasilinear system of equations.
