The article discusses the history of the Research Institute of Economics and Management of Industrial Agriculture in the Central Black Earth Region of the Russian Federation, which was merged with Dokuchaev Research Institute of Agriculture of the Central Black Earth Region in 2020.Long-term cooperation between these research institutions involved
Abstract Explosively formed projectile (EFP) has the advantages of high flight speed, high burst height, insensitivity to initial velocity, etc.To study the forming performance of multiple explosively formed projectile (MEFP) and to analyze the factors influencing the forming results.A directional pentagonal prism MEFP with five liners is proposed
A new annular lift fan configuration that has very high lift efficiency is explored by using a numerical scheme.The inlet lip radius and diffuser angle are maximized by semicircle duct walls and the location of the lift fan is moved from the throat to the diffuser area to maximize the diffusion effect of the ducted fan.The improved lift fan achieve
Immunostimulatory gene therapy has been developed Chaste Berry ( Vitex ) during the past twenty years.The aim of immunostimulatory gene therapy is to tilt the suppressive tumor microenvironment to promote anti-tumor immunity.Hence, like a Trojan horse, the gene vehicle can carry warriors and weapons into enemy territory to combat the tumor from wit
Ionospheric phase delay can seriously affect the low-frequency spaceborne synthetic aperture radar (SAR) systems.Ionospheric correction is, therefore, vital to improving the measurement accuracy of Interferometric SAR (InSAR).InSAR ionospheric correction relies mainly on two kinds of approaches, i.e., one uses SAR azimuth offsets measures, and the
