The indicated differences in the compositions of impurities (particularly ones crystallized on grain boundaries, in the first place, of lead, antimony and bismuth) allow one to predict a higher scatter of the main indices of copper rod: specific ohmic resistance, a number of rotations before fracture, plastic metal properties, copper density.
Firstly, owing to the ductility reduction the portion number decreased from 6 to 4.

The noted integral models include a number of mathematical models for the quantitative description of the complex evolution of austenite microstructure at the hot rolling stage [7-14], as well as its decomposition during subsequent accelerated cooling with the formation of a set of practically important structural components [15-17].

The fine aggregate used is broken oil palm clinker which passes through sieve number 5 and below.
Sufficient numbers of oil palm lightweight concrete specimens were casted and tested for compression, flexure, density and modulus of elasticity.
It shows that fine aggregate has higher moisture content due to the fact that smaller grain can hold more water.

By increasing the number of coefficients, the agreement between the predicted flow stress and the experimental one gets worse, causing a decrease in the R2 from a value of 0.972 for the H-S law with 5 coefficients to a value of 0.939 for the H-S law with 9 coefficients, as shown in Fig. 7 and Fig. 8.

Its configurations are described by the occupation number sets {nqi} where q is p or v; nqi is 1 when site i is occupied by an atom q and zero otherwise; and ∑ q nqi ≡ 1.
Thus, in the last term of SKE (6), the full fluctuative transfer δn f ij should be replaced by its long-wave (or ``coarse-grained'') part δn fc ij .
This maximum thermodynamic gain should evidently correspond to formation of the maximum number of large supercritical precipitates.
Average number of copper atoms within a precipitate versus the evolution time t (in seconds).
