DEPENDENCE OF INNER TRANSPORTATION EXPENSES FROM FARM LAND AREA
DescriptionServing enlarged territory is linking with speed growth expenses for distances overcoming. It is typical for shops, hospitals, schools, telecommunications, fire-brigades, civil administrations and others. Especially that influence on increasing of transportation expenses for large farms which depends in second power from its agriculture land square. It absorbs large scale production effects. Therefore small farms works successfully in market conditions of USA, Poland, Germany and other countries

CONCEPTUAL PROVISIONS OF MAKING A NEW SYSTEM TRANSPORT AND ROAD COMPLEX MODEL
DescriptionThe results of existing system models of Transport and Road Complex (TRC) are given and the necessity to overcome their incompleteness is substantiated making use of elements reflecting their social and economic origin as well as the influence of developing infrastructure of TRC, with many services provided and consumed in public and private sectors of economy. The article can be useful for economists and technical specialists tackling the problems of TRC development, its management, administration and road traffic safety

SIMULATION OF TURBULENT TRANSPORT IN THE ATMOSPHERE PARTS 1, 2
01.00.00 Physical-mathematical sciences
DescriptionThe completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows over rough surface. Numerical solutions of equations system of turbulent transport of admixtures in a surface layer of the atmosphere for a large scale have been studied
