The first Stokes method in the problem of waves on a liquid surface of finite depth
An approximate solution of the problem of the structure and characteristics of a stationary nonlinear periodic wave on the surface of a liquid of finite depth has been obtained. The solution is as follows: first, the kinematic and dynamic conditions are simplified. The Bernoulli integral contributes to the simplification of the dynamic condition. An integral operator of convolution type ...

Natural science terminology keeps as close as possible to the dissertation text, so instead of the term “gas”, which Kant does not use, the translator resorts to a loan-translation “elastic liquid,” harking back to the Russian term упругая жидкость (elastic liquid) which was proposed by Mikhail V. Lomonosov but did not catch on. For the same reason the translator uses the loan translation “moment” instead of the more ...
Simulation of turbulent flow of viscous liquids with dispersed inclusions of close density
The authors consider the methods and algorithms for calculating the characteristics of hydro-mechanical processes in the flow of viscous liquid (water) with dispersed inclusions of close density. In particular, the dependences of the dimensionless intensity of the pulsation energy dissipation on the inertness of inclusions at different loads are investigated. The paper presents the ...

A new type of ecosensor for an express analysis of liquid objects
This article presents a completely new type of ecosensors manufactured from chalcogenide glass and designed to analyse liquid objects based on the in-terpretation of ion-resistive effect as an oxidant-resistive one. The oxidant-resistive effect and its first successful applications in chemical analysis helped to develop a new area of electrochemical analysis methods — ...
The legal regulation of agricultural cooperation during the period of the Provisional Government and Soviet Russia
The study examines the transformation of the legal status of agricultural cooperatives in Russia from the period when the Provisional Government came to power to 1929, the period when this type of cooperation was liquidated as a separate entity. The study demonstrates changes in cooperative legislation after the February Revolution of 1917 until the late 1920s — from expanding the democratic foundations of cooperative societies to the complete abolition of agricultural ...

Portfolio optimization in the case of an exponential utility function and in the presence of an illiquid asset
We study an optimization problem for a portfolio with a risk-free, a liquid, and an illiquid risky asset. The illiquid risky asset is sold in an exogenous random moment with a prescribed liquidation time distribution. We assume that the investor chooses an exponential utility function. Study of optimization problems with three assets including an illiquid asset leads to three-dimensional nonlinear Hamilton — Jacobi — Bellman (HJB) ...

The authors measured liver volume in thirty-three corpses by placing the liver in water and calculating the displaced volume of the liquid. Liver was measured in each case. The data were then compared with the ones obtained by using five different formulas comprising linear liver measurements.
