Design characteristics of road embankments made of sandy soils

Sandy soils are widespread all over the world, including in Uzbekistan, and they are widely used in the construction of highways. Therefore, several regulatory documents have been developed that normalize their design characteristics. However, in the existing regulatory documents, the design characteristics of sandy soils of road embankments of highways used in the design of road coverings (modulus of elasticity E, angle of internal friction φ, specific adhesion C) are not normalized depending on the degree of compaction, calculated humidity and the content of dusty and clay particles in such soils. To solve these problems, special laboratory and field studies were conducted, the results of which are given in this article

WATER FLOW TO THE EARTH GROUND SOIL OF AUTOMOBILE ROADS FROM ATMOSPHERIC SEDIMENTS

To predict the density, moisture and heaving of soils that they will have during the operation of roads, it is necessary to determine the flow of water into the soil from precipitation falling on the surface of the carriageway and roadsides in the autumn period of moisture accumulation grounds. Therefore, this article provides a method for determining the flow of water into the soil of the road bed from precipitation

A new dynamical mechanism of incomplete fusion in heavy-ion collision

The incomplete fusion has been proved as the formation and emission of the $\alpha$ particle by the increase in the rotational energy of the very mass-asymmetric dinuclear system. The results of the dinuclear system model have confirmed that the incomplete fusion in heavy-ion collisions occurs at a large orbital angular momentum ($L > 30 \hbar$) due to the strong increase of the intrinsic fusion barrier.Comment: 6 pages, 11 figure

Engineering and blue-collar occupations prestige in the minds of industrial city students (Naberezhniye Chelny city experience)

© Published under licence by IOP Publishing Ltd. In this research work an attempt is made to reveal the factors and level of engineering and working professions prestige in the minds of studying youth on the basis of empiric data. The results of research allow revealing the mechanism of social-professional selfidentification of school-aged youth, on the basis of which an opportunity to study in a new way traditional system of profession-oriented work appears

Convergence of the Imaginary Parts of Simplest Fractions in L p(ℝ) for p < 1

© 2014, Springer Science+Business Media New York. For p ∈ (1/2, 1), the Lp(ℝ)-convergence of the series (formula presented) are some points on the complex plane. The problem is solved completely in the case where the sequence {Re zk} has no limit points. The case where this sequence has finitely many limit points is also studied

On critical values of polynomials with real critical points

Let f be a polynomial of degree at least 2 with f(0)=0 and f′(0)=1. Suppose that all the zeros of f′ are real. We show that there is a zero ζ of f′ such that {pipe} f(ζ)/ζ{pipe} ≤ 2/3, and that this inequality can be taken to be strict unless f is of the form f(z)=z+cz3. © 2009 Springer Science+Business Media, LLC

Smales problem for critical points on certain two rays

Let f be a polynomial of degree n ≥ 2 with f(0)= 0 and f′(0)= 1. We prove that there is a critical point ζ of f with |f(ζ)/ζ| ≤ 1/2 provided that the critical points of f lie in the sector {re iθ:r > 0,|θ| ≤ π/6}, and |f(ζ)/ζ| < 2/3 if they lie in the union of the two rays {1+re±iθ:r ≥ 0}, where 0 < θ ≤ π /2.

Viscous flow through straight pore channels

Steady laminar viscous 2-D flow through straight cylindrical tubes is studied. By comparison of the film-type Averyanov flow in an annular domain and the common Poiseuille flow in a circular tube, it is deduced why at high suctions sands are less conductive than clays. Flows in noncircular tubes with cusps modeling contact zones of solid particles are considered. Using conformal mappings, the Poisson equation in the physical plane is reduced to the Laplace equation in an auxiliary disk. The Dirichlet problem in this disk is solved by the Poisson integral formula. The value of maximal velocity at the center of the tube and the total flow rate (conductivity) are calculated.
