The first two in the sequence are by far the most common; 'tertiary' appears occasionally, and higher numbers are rare except in specialized contexts ('quaternary period'). The Greek series proto- , deutero- , trito- , ... is only found in prefixes, generally scholarly and technical coinages, e.g. protagonist, deuteragonist, tritagonist ...
Creep behavior can be split into three main stages. In primary, or transient, creep, the strain rate is a function of time. In Class M materials, which include most pure materials, primary strain rate decreases over time. This can be due to increasing dislocation density, or it can be due to evolving grain size. In class A materials, which have ...
• The creep resistance of hard and brittle materials was significantly influenced by small amounts of strain, although visible creep cavities or cracks were not observed. • Laboratory-damaged or ex-service materials showed negligible primary or secondary creep during subsequent testing.
Some materials have a very small secondary creep state and may go straight from the primary creep to the tertiary creep state. This is dependent on the properties of the material that is being tested. This is important to note because going straight to the tertiary state causes the material to break faster from its form. [6]

Educational stages are subdivisions of formal learning, typically covering early childhood education, primary education, secondary education and tertiary education.The United Nations Educational, Scientific and Cultural Organization recognizes nine levels of education in its International Standard Classification of Education (ISCED) system (from Level 0 (pre-primary education) through Level 8 ...
Three sectors according to Fourastié Clark's sector model This figure illustrates the percentages of a country's economy made up by different sector. The figure illustrates that countries with higher levels of socio-economic development tend to have less of their economy made up of primary and secondary sectors and more emphasis in tertiary sectors.
As with primary stress, the position of secondary stress may be more or less predictable depending on language. In English, it is not fully predictable, but the different secondary stress of the words organization and accumulation (on the first and second syllable, respectively) is predictable due to the same stress of the verbs órganize and ...
