“…This concept is emphasized by the observation that plant tissue and cell cultures render crystals identical to those in the original plant [87]. One can speculate that major regulatory steps leading to crystal formation and growth, including oxalate synthesis, calcium uptake by the plant and accumulation by idioblasts, might be highly conserved among species.…”

“…When various polymer materials are used in machine building applications their properties change: they deteriorate. Ageing of a material under operation or storage conditions is a result of a wide range of chemical and physical conversions that occur in complex multiple component systems [1][2][3][4].…”

Polypropylene expansion tanks have been subjected to accelerated weathering testing according to the developed procedure of accelerated weathering testing. The objective of the study was to determine an arbitrary lifetime of tanks under operating conditions at higher temperatures, humidity, and UV radiation (climate regions of India and Venezuela). As a result of the studies of the polypropylene expansion tanks the following has been established: the failure of the both tank types (A and B) occurred in the area of the weld in the upper and lower part after four arbitrary years of accelerated weathering testing; the stress-strain behaviour in the outer tank walls is influenced by the interior structure of the partitions. The tanks with a larger opening in the partitions feature significant deformations when the inner pressure increases as a result of a higher temperature; the “sensitive indicators” of ageing and failure of the tank material have been found: elongation at break, flexural modulus, and impact strength.
