The plants were grown on the substrates, collected at different distances from the tailing dump, and then the sprouts were watered with sewage of the mining works, containing a great number of heavy metals.
It is the first visually discernible reaction of the population to the action of tails that manifests itself in increasing sterility of the pollen grains and the lowered sprouting of seeds as well as in the change of the morphological features and appearance of teratogene effects (deformities).

This could be the grain boundary of an alloy at micro scale, the interface between fibre and matrix of a composite or an interface of a compound consisting of coating and substrate (see Fig. 1 left-hand side).
Further on, the algebraic conditioning number of the Jacobian is well-posed regardless of whether the system is undamaged or damaged.

It has a grain size up to 1 mm and is delivered as a dry-mix to be activated with water at the time of making the mixture.

Surface and grain morphology of the nanostructured layer grown by CSD method were studied using Atomic Force Microscopy (AFM).
In general, it is well reported and studied that threshold voltage is a point at which the conductivity type of the interface layer changes from n-type to p-type conductivity because more holes (positive charge) have been attracted to the interface surface and that sway the number of electrons that existed at the surface at flatband due to that surface inverts its conduction form n-type to p-type.

Studies conducted to determine the influence of the laser beam on SMA's have reported an increased susceptibility to the formation of intermetallic compounds, different grain sizes, the presence of residual stresses, or affinity for atmospheric gases. [8, 10-16].

Alost all ocean engineering structures are welding structures, so a certain size and number of defects are unavoidable.
Micro-fracture mechanics is concerned with fracture process in crystal grain size, such as dislocation.

Basaran and Chandaroy formulate a dependency of the material viscoplastic behavior with its microstructure changes by introducing a grain size variable [13].
Formulation of the viscoplastic constitutive equations The unification of the inelastic deformations and the description of several physical material states are inducing in nature a huge number of material parameters and a coupled set of stiff and first order differential equations which couldn’t be integrated without accurate and stable numerical methods.

Based on this and step by step in territory of the Czech Republic, a number of gypsum-free binders [6, 8, 9, 10] has been developed, namely: modified quick-binding high strength cement cl. 0 to IV (MRVC) – the cement class was in dependence on its specific surface; quick-binding cement lute (RVCT), and gypsum-free quick-setting cement (BSRVC).
Concrete: aggregates, grain size Dmax Î (8; 32 mm).

Although cast components may exhibit a complex dispersion of second phases, porosity and inclusions, experimental correlations between mechanical properties and dendritic spacings/grains diameter are of prime importance [5].
A number of works emphasize a clear correlation between the dendritic arrangement and properties such as the tensile strength and ductility.

It can be seen that the conventional screen-printed silver paste/dielectric electrode (Fig. 6(a)) is characterized by a great number of residual pores created during the binder burn-out process.
The non-equivalent replacement of Ag+ for Pb2+ will produce free electrons in the grains.
