Píča
Píča (Czech pronunciation: [piːt͡ʃa]), sometimes short piča or pyča [pit͡ʃa]/[pɪt͡ʃa], is a Czech and Slovak profanity that refers to the vagina similar to the English word cunt. It is often represented as a symbol of a spearhead, a rhombus standing on one of its sharper points with a vertical line in the middle, representing a vulva.

The meaning is clear for Czechs, Slovaks and Hungarians. In some other languages it has other spellings (e.g. in the non-Slavic Hungarian language it is written as "picsa"), but has similar pronunciation and carries the same meaning and profanity. Drawing this symbol is considered a taboo, or at least unaccepted by mainstream society.

The word píča is of a feminine gender, in order to insult also men Czechs derived its masculine form píčus.

Rhombus
In geometry, a rhombus (pl.: rhombi or rhombuses) is an equilateral quadrilateral, a quadrilateral whose four sides all have the same length. Other names for rhombus include diamond, lozenge, and calisson.

Every rhombus is a simple polygon (having no self-intersections). A rhombus is a special case of a parallelogram and a kite. A rhombus with right angles is a square. A non-square rhombus has two opposite acute angles and two opposite obtuse angles.
1809 in paleontology
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1809.

Burrow
A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interaction types, including symbiosis and competition. Many animal species are known to form burrows. These species range from small amphipods, to very large vertebrate species such as the polar bear. Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length; an example of the latter level of complexity, a well-developed burrow, would be a rabbit warren.
Edward Muhl
Edward Ellsworth Muhl (February 17, 1907 – April 22, 2001) was an American businessman and executive best known for serving as the head of production for Universal Pictures from 1953 until his retirement in 1973.

According to one writer, he played key roles in some of the studio's most important decisions. Muhl's contributions range from the technical (he was instrumental in persuading studio heads to shoot most of their films in Technicolor rather than the cheaper black-and-white) to the purely business (he made the deal that allowed MCA to purchase Universal in the early 1960s).

Senior management
Senior management, executive management, or upper management is an occupation at the highest level of management of an organization, performed by individuals who have the day-to-day tasks of managing the organization, sometimes a company or a corporation.
Panicum niihauense
Panicum niihauense is a rare species of grass known by the common names lau ʻehu and Niʻihau panicgrass. It is endemic to Hawaii, where it has been found on the islands of Niʻihau and Kauaʻi. It has not been observed on Niʻihau since 1949, and there are fewer than 40 individuals remaining on Kauaʻi, not counting a few individuals that have been deliberately planted in appropriate habitat. The grass is a federally listed endangered species of the United States.

The only naturally occurring specimens of the grass grow in Polihale State Park. There they grow on sand dunes and they are threatened by the use of off-road vehicles. The habitat is also impacted by the invasion of non-native plants such as Chloris barbata (swollen fingergrass), Leucaena leucocephala (haole koa), Prosopis pallida (kiawe), Atriplex semibaccata (Australian saltbush), and Verbesina encelioides (golden crown-beard).

Polihale State Park
Polihale State Park is a remote wild beach on the western side of the Hawaiian island of Kauaʻi. It is the most western publicly accessible area in Hawaii, although the privately owned island of Niʻihau is farther west. The park is miles away from the town of Kekaha, and it can only be reached via a poorly marked, dirt sugarcane road, making a four-wheel drive vehicle preferable. The beach is several miles long, yet only the area known as "Queen's Pond" offers safe swimming.
Intravesical drug delivery
Intravesical drug delivery is the delivery of medications directly into the bladder by urinary catheter. This method of drug delivery is used to directly target diseases of the bladder such as interstitial cystitis and bladder cancer, but currently faces obstacles such as low drug retention time due to washing out with urine and issues with the low permeability of the bladder wall itself. Due to the advantages of directly targeting the bladder, as well as the effectiveness of permeability enhancers, advances in intravesical drug carriers, and mucoadhesive, intravesical drug delivery is becoming more effective and of increased interest in the medical community.

Bladder
The bladder (from Old English  blædre 'bladder, blister, pimple') is a hollow organ in humans and other vertebrates that stores urine from the kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. In humans, the bladder is a distensible organ that sits on the pelvic floor. The typical adult human bladder will hold between 300 and 500 ml (10 and 17 fl oz) before the urge to empty occurs, but can hold considerably more.

The Latin phrase for "urinary bladder" is vesica urinaria, and the term vesical or prefix vesico- appear in connection with associated structures such as vesical veins. The modern Latin word for "bladder" – cystis – appears in associated terms such as cystitis (inflammation of the bladder).
O Sech'ang
O Sech'ang (Korean: 오세창; Hanja: 吳世昌, 6 August 1864 – 16 April 1953), art name Wich'ang (위창; 葦滄; 韙傖), was a Korean politician, politician, writer, calligrapher-painter (서화가; 書畫家; seohwaga), and Korean independence activist.

He is known for his writings on Korean calligraphy-paintings and epigraphy, such as Geunyeok seohwi (근역서휘; 槿域書彙) and Geunyeok insu (근역인수; 槿域印藪), Geunyeok seohwajing (근역서화징; 槿域書畵徵), an encyclopaedia of Korean art history, as well as his active engagement in journalism, art, and politics.

Art name
An art name (pseudonym or pen name), also known by its native names hào (in Mandarin Chinese), gō (in Japanese), ho (in Korean), and tên hiệu (in Vietnamese), is a professional name used by artists, poets and writers in the Sinosphere. The word and the concept originated in China, where it was used as nicknames for the educated, then became popular in other East Asian countries (especially in Japan, Korea, Vietnam, and the former Kingdom of Ryukyu).

In some cases, artists adopted different pseudonyms at different stages of their career, usually to mark significant changes in their life. Extreme practitioners of this tendency were Tang Yin of the Ming dynasty, who had more than ten hao, Hokusai of Japan, who in the period 1798 to 1806 alone used no fewer than six, and Kim Chŏnghŭi of the Joseon Dynasty who had up to 503.
Cibotium menziesii
Cibotium menziesii, the hāpuʻu ʻiʻi or Hawaiian tree fern, is a species of tree fern (Family Cybotiaceae)  that is endemic to the islands of Hawaiʻi. It is named after the Scottish naturalist Archibald Menzies.  It is also known as the male tree fern, and Cibotium glaucum is deemed the female tree fern due to differences in color.

Cyatheales
The order Cyatheales, which includes most tree ferns, is a taxonomic order of the fern class, Polypodiopsida. No clear morphological features characterize all of the Cyatheales, but DNA sequence data indicate the order is monophyletic. Some species in the Cyatheales have tree-like growth forms from a vertical rhizome, others have shorter or horizontal expanding rhizomes.

Some species have scales on the stems and leaves, while others have hairs. However, most plants in the Cyatheales are tree ferns and have trunk-like stems up to 10 metres (33 ft) tall. It is unclear how many times the tree form has evolved and been lost in the order.
Palazzo Colonna
The Palazzo Colonna (Italian pronunciation: [paˈlattso koˈlonna, - koˈlɔnna]) is a palatial block of buildings in central Rome, Italy, at the base of the Quirinal Hill, and adjacent to the church of Santi Apostoli.

The district borders the districts of Qakh, Shaki, Agdash, Barda, Tartar, Goranboy, and Samukh. Its capital and largest city is Yevlakh. As of 2020, the district had a population of 129,700. The southeast section of Mingachevir reservoir is in this district.
Radial velocity
The radial velocity or line-of-sight velocity of a target with respect to an observer is the rate of change of the vector displacement between the two points. It is formulated as the vector projection of the target-observer relative velocity onto the relative direction or line-of-sight (LOS) connecting the two points.

The radial speed or range rate is the temporal rate of the distance or range between the two points. It is a signed scalar quantity, formulated as the scalar projection of the relative velocity vector onto the LOS direction. Equivalently, radial speed equals the norm of the radial velocity, modulo the sign.

In astronomy, the point is usually taken to be the observer on Earth, so the radial velocity then denotes the speed with which the object moves away from the Earth (or approaches it, for a negative radial velocity).

Modulo (mathematics)
In mathematics, the term modulo ("with respect to a modulus of", the Latin ablative of modulus which itself means "a small measure") is often used to assert that two distinct mathematical objects can be regarded as equivalent—if their difference is accounted for by an additional factor. It was initially introduced into mathematics in the context of modular arithmetic by Carl Friedrich Gauss in 1801. Since then, the term has gained many meanings—some exact and some imprecise (such as equating "modulo" with "except for"). For the most part, the term often occurs in statements of the form:

A is the same as B modulo C

which is often equivalent to "A is the same as B up to C", and means

A and B are the same—except for differences accounted for or explained by C.

Black January
Black January (Azerbaijani: Qara Yanvar), also known as Black Saturday or the January Massacre, was a violent crackdown on Azerbaijani nationalism and anti-Soviet sentiment in Baku on 19–20 January 1990, as part of a state of emergency during the dissolution of the Soviet Union.

General Secretary of the Soviet Communist Party Mikhail Gorbachev and Defence Minister Dmitry Yazov asserted that military law was necessary to thwart efforts by the Azerbaijani independence movement to overthrow the Soviet Azerbaijani government. According to official estimates of Azerbaijan, 147 civilians were killed, 800 people were injured, and five people went missing.

In a resolution of 22 January 1990, the Supreme Soviet of Azerbaijan SSR declared that the decree of the Presidium of the Supreme Soviet of the USSR of 19 January, used to impose emergency rule in Baku and military deployment, constituted an act of aggression.

Azerbaijani nationalism
Azerbaijani nationalism (Azerbaijani: Azərbaycan milliyətçiliyi), also referred to as Azerbaijanism (Azerbaijani: Azərbaycançılıq) originated as a result of the Pan-Turkist agenda expressed during the October Revolution and historiography under the Soviet Union.

Azerbaijani nationalism is characterized by irredentist and expansionist territorial claims to regions in Iran, Nagorno-Karabakh, and Armenia.
