This article discusses the use of nuclear magnetic resonance spectroscopy for the determination of biologically active substances-producing plants in the culture of in vitro and in situ. The same is said about the benefits of obtaining biologically active substances from plants in culture in vitro. Formulated a number of problems for theoretical study and experimental development basic principles on the use of nuclear magnetic resonance spectroscopy in pharmaceutical analysis for standardization and quality assessment of BAS

The article presents a brand new approach to the issue of automation of a workflow of the felling head to retain the truncated tree in an upright position when it is carried out of the woods. The model of holding tree upright and a block diagram of the position control of the felling head have been presented

The article presents the methodology and the results of experimental studies to determine actual values of effort arising from uprooting trees and shrubs plan-tations in the Republic of Mari El. On the basis of experiments and regression analysis we have established the coefficients of the approximation-defining relation between the force and the diameter of the stem of tearing depending on the type of crops

The article discusses the development process for preparing an extract of lichens on the basis of use of low productivity of natural biogeocenosis using adaptive modular complex harvesting and processing of lichens for more effective use of them

The article presents investigations of engine oil with the addition of special additives and reactions of the composition in the process of friction on the metal surface, simulating the boundary and hydrodynamic friction

The article presents the mathematical model for determining the temperature after passing trough nozzles of press-granulator, which allows to take into account heat loss through the exterior surface

The article presents the approach to modeling of microprofile felling areas as the bearing surface of harvesting machines and is an example of the model obtained in the study of the behavior of wheeled vehicle on uneven support surface

During the study, the authors have solved the problem of determining the minimum number of operations by optimizing fillability of a claw-shearing device with trees. Sufficient optimality conditions have been obtained. The numerical method for solving the optimization problem was developed. We have also performed a numerical experiment

The article presents the description of the method and the results of the experimental research of loading of driving mechanism of felling head of a forest machine

The article presents the original study material designed to determine the influence of soil properties on the cross rate of the transport system. These data allow us to determine the efficiency changes compositions transport system for transporting long cargo
