Porta Nigra
The Porta Nigra (Latin for ''black gate'') is a large Roman city gate in Trier, Germany. It is today the largest Roman city gate north of the Alps. It was designated as part of the Roman Monuments, Cathedral of St Peter and Church of Our Lady in Trier UNESCO World Heritage Site in 1986, because of its testimony to the influence of Trier in the Roman Empire and its unique architecture as both a city gate and a double church. The name ''Porta Nigra'' originated in the Middle Ages due to the darkened colour of its stone; the original Roman name has not been preserved. Locals commonly refer to the Porta Nigra simply as ''Porta''. History Roman The Porta Nigra was built in grey sandstone after 170 AD. The original gate consisted of two four-storeyed towers, projecting as near semicircles on the outer side. A narrow courtyard separated the two gate openings on either side. For unknown reasons, however, the construction of the gate remained unfinished. For example, the stones at the nor ...

Rupes Nigra
Rupes (plural ) is the Latin word for 'cliff'. It is used in planetary geology to refer to escarpments on other worlds. , the IAU has named 62 such features in the Solar System, on Mercury (17), Venus (7), the Moon (8), Mars (23), the asteroids Vesta (2) and Lutetia (2), and Uranus's satellites Miranda (2) and Titania (1). How rupes formed is, , a matter of speculation. Compressional strain from the cooling of the crust of terrestrial planets and large scale displacement due to impacts are the two dominant theories. See also * Rupes on the Earth's moon * Rupes on Mercury * Rupes on Venus * Rousillon Rupes * Rupes Tenuis * Verona Rupes Verona Rupes is a cliff on Miranda, a moon of Uranus. It was discovered by the ''Voyager 2'' space probe in January 1986. The cliff face, previously thought to be from high, as of 2016 is estimated to be high, which makes it the tallest known ...

From a histological perspective, DPN resembles seborrheic keratoses. The condition may be cosmetically undesirable to some. They should not be confused for Leser-Trélat sign, a sudden explosion of lesions due to a growing tumor. Pathophysiology The pathophysiology of DPN is unknown. Evidence of family history may suggest a genetic propensity. Treatment DPN lesions are benign and no treatment generally ...

Linea Nigra
Linea nigra (Latin for "black line"), often referred to as a pregnancy line, is a linear hyperpigmentation that commonly appears on the abdomen. The brownish streak is usually about a centimeter (0.4 in) in width. The line runs vertically along the midline of the abdomen from the pubis to the umbilicus, but can also run from the pubis to the top of the abdomen. For pregnant women, linea nigra is attributed to increased melanocyte-stimulating hormone made by the placenta, which also causes melasma and darkened nipples. Fair-skinned women show this phenomenon less often than women with darker pigmentation. Linea nigra typically disappears within a few months after delivery. Although linea nigra is rarely discussed outside pregnancy, males and females of all ages may have it. Except in pregnancy, both sexes have highest and equal prevalence of linea nigra from age 11 to 15. This increase in prevalence could be the result of hormonal changes during puberty. After age 15, the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Substantia Nigra
The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement. ''Substantia nigra'' is Latin for "black substance", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons. Parkinson's disease is characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta. Although the substantia nigra appears as a continuous band in brain sections, anatomical studies have found that it actually consists of two parts with very different connections and functions: the pars compacta (SNpc) and the pars reticulata (SNpr). The pars compacta serves mainly as a projection to the basal ganglia circuit, supplying the striatum with dopamine. The pars reticulata conveys signals from the basal ganglia to numerous other brain structures. Structure The substantia nigra, along with four other nuclei, is part ...

Tinea Nigra
Tinea nigra, also known as superficial phaeohyphomycosis and Tinea nigra palmaris et plantaris, is a superficial fungal infection, a type of phaeohyphomycosis rather than a tinea, that causes usually a single 1–5 cm dark brown-black, non-scaly, flat, painless patch on the palms of the hands and the soles of the feet of healthy people. There may be multiple spots. The macules occasionally extend to the fingers, toes, and nails, and may be reported on the chest, neck, or genital area. Tinea nigra infections can present with multiple macules that can be mottled or velvety in appearance, and may be oval or irregular in shape. The macules can be anywhere from a few mm to several cm in size. Most cases are caused by ''Hortaea werneckii'', a pigmented fungus, which is a dark yeast found in sewage, soil, rotting vegetation and wood and in places with a high salt content such as moldy salted fish and on beaches, where contact with sand may result in transmission. Infection is by ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Costantino Nigra
Costantino, count Nigra (11 June 1828 – 1 July 1907) was an Italian diplomat. Biography Nigra was born at Villa Castelnuovo, in the province of Turin. During the war of 1848 he interrupted his studies to serve as a volunteer against Austria, and was wounded at the battle of Rivoli. On the conclusion of peace he entered the Piedmontese foreign office; he accompanied Victor Emmanuel and Cavour to Paris and London in 1855, and in the following year he took part in the conference of Paris by which the Crimean War was brought to an end. After the meeting at Plombières between Cavour and Napoleon III Nigra was sent to Paris again to popularize a Franco-Piedmontese alliance, Nigra being, as Cavour said, the only person perhaps who knows all my thoughts, even the most secret. He was instrumental in negotiating the marriage between Victor Emmanuel's daughter Clothilde and Napoleon's nephew, and during the war of 1859 he was always with the emperor. He was recalled from Paris when ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Patriotic Nigras
The Patriotic Nigras (also known by the initialism PN) were a group of griefers in the online world of ''Second Life''. While the PN were known mainly for the disruption of ''Second Life'' and its users, they had also established themselves on the video sharing website YouTube, where they have posted videos of their activities including server raids. Their method of attack ranges from trolling a group or individual to the manipulation of the in-game scripting engine, where they perform such activities as showering their targets with boxes covered in internet memes and shock images. These boxes then produce storms of graphical particles that block the victim's vision. They have also created avatars similar to those of the residents being harassed and destroyed them in gruesome ways to simulate a virtual death. The Patriotic Nigras have also caused the crashing of several ''Second Life'' regions (or "simulators") by using self-replicating objects that overload the processing power of ...

Negro
In the English language, ''negro'' is a term historically used to denote persons considered to be of Black African heritage. The word ''negro'' means the color black in both Spanish and in Portuguese, where English took it from. The term can be construed as offensive, inoffensive, or completely neutral, largely depending on the region or country where it is used, as well as the context in which it is applied. It has various equivalents in other languages of Europe. In English Around 1442, the Portuguese first arrived in Southern Africa while trying to find a sea route to India. The term ', literally meaning "black", was used by the Spanish and Portuguese as a simple description to refer to the Bantu peoples that they encountered. ''Negro'' denotes "black" in Spanish and Portuguese, derived from the Latin word ''niger'', meaning ''black'', which itself is probably from a Proto-Indo-European root ''*nekw-'', "to be dark", akin to ''*nokw-'', "night". ''Negro'' was also used of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
