Adjective identifying the third surface to reflect radiation in a telescope In a radio telescope, the primary reflector is usually the surface of the panels or, in a low-frequency antenna, a wire mesh This is sometimes referred to as the main reflector or simply, the dish The secondary reflector, if any, is often called the subreflector While smaller than the primary reflector, it is often large relative to a person By contrast, any tertiary reflector is usually a small device used only at high radio frequencies and which is often therefore described as a "mirror", by analogy with optical systems
A high level of wastewater treatment that repurifies the water to meet state health requirements
The first period of the Cenozoic era (after the Cretaceous of the Mesozoic era and before the Quaternary) thought to have covered the span of time between 65 and 2 Ma; also, the corresponding system of rocks
(3) Geology Of, belonging to, or being the geologic time, system of rocks, and sedimentary deposits of the first period of the Cenozoic Era, extending from the Cretaceous Period of the Mesozoic Era to the Quaternary Period of the Cenozoic Era, characterized by the appearance of modern flora and of apes and other large mammals Donkey - Equus asinus [Back To Top]
Tertiary means third in order, third in importance, or at a third stage of development. He must have come to know those philosophers through secondary or tertiary sources
One of the quill feathers which are borne upon the basal joint of the wing of a bird
Refers to a geological time period during which sedimentary material was deposited Rock were formed when this material was subsequently covered and subject to heat and pressure The rocks were later uplifted and exposed
{s} third (in order, rank, etc.); of or pertaining to the short flight feathers on a bird's wing
Possessing some quality in the third degree; having been subjected to the substitution of three atoms or radicals; as, a tertiary alcohol, amine, or salt
The geological time period lying between the Cretaceous and the Quaternary (qv), extending from about 65 to 1 6 million years ago It occupies the bulk of the Cainozoic era From oldest to youngest, the subdivisions are Palaeocene, Eocene, Oligocene, Miocene, and Pliocene Tertiary climates in Australia were mainly warm and humid, with aridity first appearing towards the end of the Miocene and becoming widespread in the Pliocene
The third mirror to be encountered by the light in a telescope system A tertiary mirror is required on alt-az telescopes to direct light to the stationary Nasmyth foci
A lay person belonging to a religious order, who lives a holy life in the community rather than observing a strict religious rule; thus member of a third order
Geologic period that occurred roughly 1 6 to 65 million years ago During this period, mammals become a dominant species on the planet
Being of the third formation, order, or rank; third; as, a tertiary use of a word
Tertiary education is education at university or college level. institutions of tertiary education. third in place, degree, or order (tertiarius , from tertius )
refers to educational institutions such as universities and polytechnical institutes; require an academic school-leaving qualification (high school diploma with college-preparatory classes - US, or secondary school A-level examinations - UK); by extension, all forms of post-secondary education
(Tıp, İlaç) Highly specialized medical care usually over an extended period of time that involves advanced and complex procedures and treatments performed by medical specialists in state-of-the-art facilities
Interval of geologic time, 65-1. 8 million years ago. It constitutes the first of the two periods of the Cenozoic Era, the second being the Quaternary. The Tertiary has five subdivisions: (from oldest to youngest) the Paleocene, Eocene, Oligocene, Miocene, and Pliocene epochs. During most of the Tertiary, the spatial distribution of the major continents was largely similar to that of today. Emergence and submergence of land bridges between continents critically affected the distribution of both terrestrial and marine animals and plants. Virtually all the existing major mountain ranges were formed either partly or wholly during the Tertiary
The tertiary sector consists of industries which provide a service, such as transport and finance. economies that are slowly increasing the proportion of their labour force in the tertiary sector
