Although the quality of potato starch is higher, it is being supplanted by poorer quality cereal starch. From Europarl Parallel Corpus - English One third of the nearly 200 wild potato species were first described by him.
This tensile test of a nodular cast iron demonstrates low ductility. In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire.uctility can be quantified by the fracture strain, which is the engineering strain at which a test specimen fractures during a uniaxial tensile test.
Metals are a common type of ductile material. Copper, aluminum, and steel are examples of ductile metals. The opposite of ductility is brittleness, where a material breaks when tensile stress is applied to lengthen it. Examples of brittle materials include cast iron, concrete, and some glass products.
