pyramidalization

Examples of pyramidalization in the following topics:

• Ecological Pyramids

  • Ecological pyramids can also be called trophic pyramids or energy pyramids.
  • Pyramids of numbers can be either upright or inverted, depending on the ecosystem.
  • Another way to visualize ecosystem structure is with pyramids of biomass.
  • Using the Silver Springs ecosystem example, this data exhibits an upright biomass pyramid, whereas the pyramid from the English Channel example is inverted .
  • As with inverted pyramids of numbers, the inverted biomass pyramid is not due to a lack of productivity from the primary producers, but results from the high turnover rate of the phytoplankton.

• The Pyramids of the Old Kingdom

  • These tombs were built in the form of great pyramids, and for this reason, the Old Kingdom is frequently referred to as "the Age of the Pyramids. "
  • In the following dynasties, the pyramid design changed from the "step" pyramid to a true pyramid shape as kings continued to build tombs for their kings.
  • The Necropolis includes three pyramid complexes: the Great Pyramid (built by King Khufu of the 4th Dynasty); the somewhat smaller Pyramid of Khafre (Khufu's son); and the relatively modest-sized Pyramid of Menkaure .
  • Djoser´s step pyramid was the first of the great pyramids built during the Old Kingdom in Eqypt.
  • This view shows all three pyramid structures: the Great Pyramid, the Pyramid of Khafre, and the Pyramid of Menkaure.

• The Old Kingdom

  • The Old Kingdom is perhaps best known for a large number of pyramids, which were constructed as royal burial places, and is often called "The Age of the Pyramids."
  • Using a greater mass of stones than any other king, he built three pyramids: Meidum, the Bent Pyramid and the Red Pyramid.
  • Sneferu was succeeded by his (in)famous son, Khufu (2589-2566 BCE), who built the Great Pyramid of Giza.
  • After Khufu's death one of his sons built the second pyramid and the Sphinx in Giza.
  • The Great Pyramid of Giza was built c. 2560 BCE by Khufu during the Fourth Dynasty.

• Egyptian Monuments

  • Ancient Egyptian monuments included pyramids, sphinxes and temples.
  • About 135 pyramids have been discovered in Egypt, with the largest (in Egypt and the world) being the Great Pyramid of Giza.
  • The Giza Necropolis, built in the Fourth Dynasty, includes the Pyramid of Khufu (also known as the Great Pyramid or the Pyramid of Cheops), the Pyramid of Khafre and the Pyramid of Menkaure, along with smaller "queens" pyramids and the Great Sphinx.
  • Here the Great Sphinx is shown against the Pyramid of Kahfre.
  • A map showing the layout of the Giza Pyramid area, including the Pyramids of Khufu, Khafre, Menkaure and the Great Sphinx.

• Tombs

  • During the Old Kingdom, mastabas and pyramids were built as tombs for the deceased in order to preserve their soul in the afterlife.
  • During the Old Kingdom, these royal mastabas eventually developed into rock-cut "step pyramids" and then "true pyramids," although non-royal use of mastabas continued to be used for more than a thousand years.
  • The Pyramids of Giza, massive stone-cut structures built from limestone quarried from the Nile River,are the most well-known example of pyramid tombs built during the Old Kingdom .
  • As the pyramids were constructed for the kings, mastabas for lesser royals were constructed around them.
  • The Pyramids of Giza served as tombs to the Kings.

• Organization of Motor Neuron Pathways

  • It consists of the pyramidal and extrapyramidal system.
  • The motor impulses originate in the giant pyramidal cells (Betz cells) of the motor area, i.e., precentral gyrus of the cerebral cortex.
  • Cortical upper motor neurons originate from Brodmann areas 1, 2, 3, 4, and 6, then descend into the posterior limb of the internal capsule, through the crus cerebri, down through the pons, and to the medullary pyramids, where about 90% of the axons cross to the contralateral side at the decussation of the pyramids.
  • Included in the diagram are the following motor pathways: corticospinal tracts (pyramidal tract), and extrapyramidal tracts (tectospinal tract not delineated).
  • Lateral view; "pyramidal tract" visible in red, and "pyramidal decussation" labeled at lower right.

• Architecture of the Middle Kingdom

  • It is one of the five remaining pyramids of the original eleven pyramids at Dahshur in Egypt.
  • Originally named Amenemhet is Mighty, the pyramid earned the name "Black Pyramid" for its dark, decaying appearance as a rubble mound.
  • Typical for Middle Kingdom pyramids, the Black Pyramid, although encased in limestone, is made of mud brick and clay instead of stone.
  • Workers' villages were often built nearby to pyramid construction sites.
  • Middle Kingdom pyramids consist of mud brick and clay encased in limestone.

• The people at the bottom of the pyramid

  • ‘Inclusive business' is the term used to describe efforts that include ‘bottom-of-the-pyramid' (BoP) customers in a company's business model – and the key to tapping into this powerful economic base is ‘local partner selection'.

• Art and Architecture in the Kingdom of Kush

  • The kings of Kush adopted the Egyptian architectural idea of building pyramids as funerary monuments.
  • However, Kushite pyramids were built above the underground graves, whereas the Egyptian graves were inside the pyramid.
  • The kings' tombs were lodged under large pyramids made of stone.
  • Ordinary citizens were buried in much smaller pyramids.
  • The most famous examples of Kushite pyramids are located in their capital Meroë.

• Teotihuacan

  • Teotihuacan was a city founded outside of modern Mexico City in 100 BCE and was known for its pyramids.
  • It is famous for its pyramids and series of accompanying residential compounds, but was once much more than an archaeological and tourist site.
  • The city's broad central avenue, called "Avenue of the Dead" (a translation from its Nahuatl name Miccoatli), is flanked by impressive ceremonial architecture, including the immense Pyramid of the Sun (third largest in the World after the Great Pyramid of Cholula and the Great Pyramid of Giza) and the Pyramid of the Moon.
  • It also enabled them to orient the Pyramids to the distant mountain that was out of sight.
  • This giant pyramid dwarfs the smaller platforms surrounding it and was the largest building at Teotihuacan.
