Context paragraphs:
Scaphyglottis: Scaphyglottis is a genus of orchids native to Mexico, Central America, northern South America and parts of the Caribbean.  The current concept of this genus is the result of combining several genera which have been described at various times.  The concept is characterized by the growth habit: not only are new pseudobulbs added at the base of the old ones (as is typical of sympodial orchids), but new pseudobulbs also grow at the apices of the old ones.  Many species are quite similar and difficult to distinguish, but some are clearly distinct.  A few have showy colors.  The genus comprises nearly 70 species.

Old Ones (Buffy the Vampire Slayer): In the Buffyverse, the Old Ones are the extremely powerful, pure-breed demons that once dominated Earth before humankind appeared.  Illyria is one of these demons (though its real form was revealed only in an illustration) while it's more than likely that Jasmine and her kind (The Powers That Be) ascended to their higher plane because of the growing malevolence of these warring demons.  It's also possible that the Powers that Be were part of the same race but shared a different philosophy than the other Old Ones.

Unspeakable Vault (of Doom): The Unspeakable Vault (of Doom) or Weird Tales from the Old Ones is a webcomic by François Launet, which chronicles the "daily" lives of the Great Old Ones, including Cthulhu, Nyarlathotep, and Yog-Sothoth, among others.  It takes a lighthearted view of H. P. Lovecraft's Cthulhu Mythos to inspire laughter rather than the more usual soul-blasting horror.  The comic was used as the basis of the second expansion set to the Cthulhu Mythos themed version of Steve Jackson Games' card game "Munchkin".

Alien Intelligence (Palladium Books): In the various game settings of Palladium Books, Alien Intelligences are fictional, vastly powerful beings of unknown origin that are stated to be a combination of equal parts spirit, magical energy, and physical flesh.  They are said to exist on different planes of existence simultaneously, and in the Palladium hierarchy of powers, most Alien Intelligences, apart from the Vampire Intelligences, are more powerful than the mightiest Gods in Palladium.  In fact, some of the most powerful Gods of the Palladium Megaverse were themselves spawned by the Alien Intelligences.

Presuppositional apologetics: Presuppositionalism is a school of Christian apologetics that believes the Christian faith is the only basis for rational thought.  It presupposes that the Bible is divine revelation and attempts to expose flaws in other worldviews.  It claims that apart from presuppositions, one could not make sense of any human experience, and there can be no set of neutral assumptions from which to reason with a non-Christian.  Presuppositionalists claim that a Christian cannot consistently declare their belief in the necessary existence of the God of the Bible and simultaneously argue on the basis of a different set of assumptions that God may not exist and Biblical revelation may not be true.  Two schools of presuppositionalism exist, based on the different teachings of Cornelius Van Til and Gordon Haddon Clark.  Presuppositionalism contrasts with classical apologetics and evidential apologetics.

Chaos (Warhammer): In Games Workshop's "Warhammer Fantasy" and "Warhammer 40,000" fictional universes, Chaos refers to the malevolent entities which live in a different timespace, known as the Warp in "Warhammer 40,000" and as the Realm of Chaos in "Warhammer Fantasy".  The term can refer to these warp entities and their influence, the servants and worshippers of these entities, or even the parallel universe in which these entities are supposed to reside.  The most powerful of these warp entities are those known as the Chaos Gods, also sometimes referred to as the Dark Gods, Ruinous Powers, or the Powers of Chaos.  Similarities exist between the Warhammer idea of Chaos and the concept of Chaos from Michael Moorcock's Elric saga, which also influenced D&D's alignment system.  Further similarities can be seen with the godlike extradimensional Great Old Ones of horror writer H. P. Lovecraft's stories.

Old Ones (Palladium Books): The Old Ones (sometimes referred to in Palladium Books publications as the Great Old Ones or the Unnameable Beings) are a fictional race of Alien Intelligences within the megaversal setting of Palladium Books' game module PFRPG.  The Old Ones are the most powerful forces ever to have existed in the various Palladium game settings, and their power dwarfs that of 'ordinary' Alien Intelligences, beings which are in general far more powerful than the gods themselves.

Multifocal plane microscopy: Multifocal plane microscopy (MUM) or Multiplane microscopy or Biplane microscopy is a form of light microscopy that allows the tracking of the 3D dynamics in live cells at high temporal and spatial resolution by simultaneously imaging different focal planes within the specimen.  In this methodology, the light collected from the sample by an infinity-corrected objective lens is split into two paths.  In each path the split light is focused onto a detector which is placed at a specific calibrated distance from the tube lens.  In this way, each detector images a distinct plane within the sample.  The first developed MUM setup was capable of imaging two distinct planes within the sample.  However, the setup can be modified to image more than two planes by further splitting the light in each light path and focusing it onto detectors placed at specific calibrated distances.  Another technique called multifocus microscopy (MFM) uses diffractive Fourier optics to image up to 25 focal planes.  Presently, MUM setups are implemented that can image up to four distinct planes.

List of The Power of Five characters: This is a list of all the antagonists and protagonists in "The Power of Five" series by Anthony Horowitz.  The series chronicles the war between the Old Ones and the Five Gatekeepers.  The Five are Matthew Freeman/Jesus, Pedro/Inti, Scott and Jamie Tyler (Flint and Sapling) and Scarlett Adams (Scar, or Lin Mo, the Chinese goddess of the sea).  The Old Ones ruled the world for eighty years at the dawn of humanity, but the Five defeated them, and threw them into Hell, causing the demons to await their return for millennia.  Two gates were built in between Earth and Hell to keep the Old Ones out - these are the focus of the series and consist of Raven's Gate, and the Nazca Desert, which is the second gate.

Hyderabad Colony was originally inhabited by Hyderabadi Muslim migrants from Hyderabad Deccan.  It is famous for its popular Hyderabadi food, including Hyderabadi biryani, chaakna, Hyderabad Haleem and especially achar (pickle).  Abu Mian, a catering service popular among the Hyderabadis of Karachi, is located in Hyderabad Colony.  The first Mosque in the neighbourhood was the Makkah Masjid which was the center of the social and religious activity in the vicinity.  Muhammad Multani Qadri was the first president of the Makkah Mosque Foundation and was a well-known and respectable elder in the colony.  Currently, the colony is fast changing its actual look and surroundings.  With recently constructed flyover near Central Jail and speedy construction of flats, the area is now completely different from the one that used to be in early 1980s.  Few of the old shops still exist but most of the old ones are either transformed or closed.Nasar Ullah Khan Shajee was also born at Hyderabad colony and elected Member of Sind Assembly . Prominent politician and Naib Ameer of a politico-religious party Jamaat-e-Islami (JI), Nasrullah Shaji, drowned in river while saving live of a school student during a tour in Balakot.
