Circumcoronene
Circumcoronene is a polycyclic aromatic hydrocarbon with the molecular formula C54H18. It consists of a central coronene molecule circumscribed by benzene on the periphery.

Circumcoronene is the third benzenoid hydrocarbon in the benzene-coronene-circumcoronene series. It comes after benzene and coronene, and is followed by circumcircumcoronene. Various topological and mathematical properties have been computed for molecules in this series.

On-surface synthesis of circumcoronene was achieved in 2021 via intramolecular dehydrogenation of a precursor hexa-peri-hexabenzocoronene, followed by methyl radical coupling and aromatization, on a Cu(111) surface. A solution-phase synthesis was reported in 2023 via acid-mediated cyclization of alkynes, confirmed via X-ray crystallographic analysis and NMR measurement.

Hexabenzocoronene
Hexa-peri-hexabenzocoronene (HBC) is a polycyclic aromatic hydrocarbon with the molecular formula C42H18. It consists of a central coronene molecule, with an additional benzene ring fused between each adjacent pair of rings around the periphery. It is sometimes simply called hexabenzocoronene, however, there are other chemicals that share this less-specific name, such as hexa-cata-hexabenzocoronene.

Hexa-peri-hexabenzocoronene has been imaged by atomic force microscopy (AFM) providing the first example of a molecule in which differences in bond order and bond lengths of the individual bonds can be distinguished by a measurement in direct space.
Stylogyne
Stylogyne is a genus of shrubs and trees in the family Primulaceae. Its members are found throughout tropical parts of the Americas, with the greatest diversity in South America. It is closely related to the genera Ardisia and Geissanthus, and various species have been transferred between the three genera. All three were formerly placed in the family Myrsinaceae, which is now treated as a subfamily (Myrsinoideae) of the Primulaceae.

Primulaceae
The Primulaceae (/ˌprɪmjəˈleɪʃi.iː/ PRIM-yə-LAY-shee-ee), commonly known as the primrose family (but not related to the evening primrose family), are a family of herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are perennial though some species, such as scarlet pimpernel, are annuals.

Previously one of three families in the order Primulales, it underwent considerable generic re-alignment once molecular phylogenetic methods were used for taxonomic classification. The order was then submerged in a much enlarged order Ericales and became a greatly enlarged Primulaceae sensu lato (s.l). In this new classification of the Angiosperm Phylogeny Group, each of the Primulales families was reduced to the rank of subfamily of Primulaceae s.l. The original Primulaceae (Primulaceae sensu stricto or s.s.) then became subfamily Primuloideae, and one genus (Maesa) was raised to the rank of a separate subfamily, making four in all.
Mason Truck
Mason Motors, founded by A. C. Mason in cooperation with William C. Durant, was a U.S. truck manufacturer based in Flint, Michigan. As a subsidiary of Durant Motors, Mason Truck built Road King Speed Trucks in the early 1920s. Mason Motors also built automobile engines in 1911, who first led Buick's engine works in Flint. That company was absorbed by Chevrolet in 1915, but remained under the Chevrolet umbrella until January 1, 1918, when it became known as the Motor and Axle Division of Chevrolet.

There were four separate automobile companies using the name "Mason" between 1898 and 1914 with locations in Massachusetts, Iowa, Illinois and New York. Records show that Mason Motors of Flint, MI was a truck manufacturer and also supplied engines for Buick use, but they did not manufacture passenger automobiles.

William C. Durant
William Crapo Durant (December 8, 1861 – March 18, 1947) was an American businessman. A leading pioneer of the United States automobile industry, he was the founder of General Motors and a co-founder of Chevrolet. He created a system in which a company held multiple brands – each seemingly independent, with different automobile lines – bound under a unified corporate holding company. He also founded Frigidaire.
Avion Pirata
Avión Pirata (Pirate Airplane) is the name given by Bolivians to a Lockheed Constellation which mysteriously carried flights into El Trompillo Airport in Santa Cruz, Bolivia, during 1961. The airplane has remained in Bolivia since 1961, when it was forced to land by the Bolivian Air Force after a chase in which an Air Force Captain died in a crash.

The airplane has become a tourist attraction, having undergone several changes of ownership, and has also become an urban legend among Bolivians.

Urban legend
Urban legend (sometimes modern legend, urban myth, or simply legend) is a genre of folklore concerning stories about an unusual (usually scary) or humorous event that many people believe to be true but largely are not.

These legends can be entertaining but often concern mysterious and troubling events, such as disappearances and strange objects or entities. Urban legends may confirm moral standards, reflect prejudices, or be a way to make sense of societal anxieties.

In the past, urban legends were most often circulated orally, at gatherings and around the campfire for instance. Now, they can be spread by any media, including newspapers, mobile news apps, e-mail, and most often, social media.  Some urban legends have passed through the years/decades with only minor changes, in where the time period takes place. Generic urban legends are often altered to suit regional variations, but the lesson or moral generally remains the same.

Before the foundation of Naypyidaw, it was known as the airport of the nearby town of Lewe. The airport officially opened on 19 December 2011. The airport's air traffic control tower collapsed during the 2025 Myanmar earthquake, killing six people.
Portuguese Cemetery, Kollam
The Portuguese Cemetery (after the invasion of Dutch, it became Dutch Cemetery) of Tangasseri in Kollam city, India, was constructed around 1519 as part of the Portuguese invasion of the city. Buckingham Canal, a small canal between Tangasseri Lighthouse and the cemetery, is situated very close to the Portuguese Cemetery. A group of pirates known as the Pirates of Tangasseri formerly lived at the Cemetery. The remnants of St. Thomas Fort and Portuguese Cemetery still exist at Tangasseri.

St Thomas Fort

It is located around 5 kilometres (3.1 mi) from the city center of Kollam and 71 kilometres (44 mi) from the state capital Thiruvananthapuram.
2018 FC Vorkuta season
The 2018 season was FC Vorkuta's second season in the Canadian Soccer League. The club ended their CSL campaign with a club record by securing their first professional championship title in the First Division, and the double in the Second Division. The club qualified for the playoffs for the second consecutive season after finishing second in the First Division. In the postseason Vorkuta defeated the likes of Real Mississauga, and SC Waterloo Region in order to reach the championship final. Their opposition in the finals were Scarborough SC, where Vorkuta claimed their first CSL Championship after a victory in a penalty shootout.

While in the Second Division their reserve team clinched the organization's first division title, and made further achievements in the postseason after winning the championship title against Halton United. The club's top goalscorer for the second consecutive season was Sergiy Ivliev with eleven goals.

Canadian Soccer League championship final
The Canadian Soccer League championship final, or CSL Championship, is the post-season match of the Canadian Soccer League (CSL) and is the successor to the CNSL Championship. The winner is crowned champion as in other North American sports leagues (i.e. via a playoff following a regular season). This differs from other top soccer leagues, which consider the club with the most points at the end of the season to be the sole champion. It is a Non-FIFA championship match that was previously sanctioned by the Canadian Soccer Association (CSA) but is now affiliated with the Soccer Federation of Canada (SFC).

The league hosted its inaugural championship on October 14, 1998. The CSL Championship is traditionally held in early October. Toronto Croatia is the most successful team, winning a record sixth cup in 2015.

Throughout its history, the championship has had several title sponsors, from the Primus Cup in 2000, the Rogers Cup from 2001 to 2009, and the Givova Cup from 2010 onwards.
Vítor Paneira
Vítor Manuel da Costa Araújo (born 16 February 1966), known as Vítor Paneira, is a Portuguese former professional footballer who played as a right midfielder, currently a manager.

He excelled in the late 80s and early 90s with Benfica, to where he arrived from the lower leagues, going on to amass Primeira Liga totals of 335 games and 43 goals over 11 seasons (289/44 in official matches with his main club). He also played for Vitória de Guimarães in the competition.

A Portugal international for eight years, Paneira represented the country at Euro 1996. In a managerial career of over 20 years, he had two spells each at Tondela and Varzim, briefly leading the former in the top flight.

1989–90 European Cup
The 1989–90 European Cup was the 35th edition of Europe's premier club football tournament, the European Cup. The final was played at the Praterstadion in Vienna on 23 May 1990. The final was contested by Italian defending champions Milan and Portuguese twice former winners Benfica. Milan successfully defended their title with a 1–0 victory, securing their fourth European Cup trophy. Milan remained the last team to successfully defend their trophy until Real Madrid did it again in 2017. Arsenal were denied a place in the competition, as this was the last year of a ban from European competitions for English clubs following the Heysel Stadium disaster of 1985.
Dometiopolis
Dometiopolis (Ancient Greek: Δομετιούπολις) was a city of Cilicia Trachea, and in the later Roman province of Isauria in Asia Minor. Its ruins are found in the village of Katranlı (formerly Dindebul), Ermenek, Karaman Province, Turkey.

Ermenek
Ermenek is a town in Karaman Province in the Mediterranean region of Turkey. It is the seat of Ermenek District. Its population is 11,629 (2022). As ancient Germanicopolis (in Isauria; has namesakes), a former bishopric, it remains a Latin Catholic titular see.

Ancient Aetolia was the core of the Aetolian League and also included parts of modern Evrytania.
Armstrong Siddeley Beta
Armstrong Siddeley Beta was an early rocket engine, intended for use in supersonic aircraft.

The Miles M.52, the intended British contender for supersonic flight, had been cancelled in 1946 due to uncertainty concerning its turbojet engine's thrust potential and the risks of crewed supersonic flight. A scale model was then built by Vickers with a 362 kg (800 lbf) thrust hydrogen peroxide 'hot' motor evolved at Westcott derived from the Walter HWK 109-509 engine. This initiated the Beta and the subsequent Delta engines. In October 1948 the Vickers Transonic model flew at 930 mph (Mach 1.5) in level flight at 35,000 ft.

To reduce the risks of single-sourced engines, other makers were given experience of work with hydrogen peroxide. In 1952 Napier were providing their NRE.17 engines for missile trials, as a line of development from Beta.

Walter HWK 109-509
The Walter HWK 109-509 was a German liquid-fuel bipropellant rocket engine that powered the Messerschmitt Me 163 Komet and Bachem Ba 349 aircraft. It was produced by Hellmuth Walter Kommanditgesellschaft (HWK) commencing in 1943, with licensed production by the Heinkel firm's facilities in Jenbach, Austria.
Sociology of space
The sociology of space is a sub-discipline of sociology that mostly borrows from theories developed within the discipline of geography, including the sub fields of human geography, economic geography, and feminist geography. The "sociology" of space examines the social and material constitution of spaces. It is concerned with understanding the social practices, institutional forces, and material complexity of how humans and spaces interact. The sociology of space is an inter-disciplinary area of study, drawing on various theoretical traditions including Marxism, postcolonialism, and Science and Technology Studies, and overlaps and encompasses theorists with various academic disciplines such as geography and architecture.  Edward T. Hall developed the study of Proxemics which concentrates on the empirical analysis of space in psychology.

Henri Lefebvre
Henri Lefebvre (/ləˈfɛvrə/ lə-FEV-rə; French: [ɑ̃ʁi ləfɛvʁ]; 16 June 1901 – 29 June 1991) was a French Marxist philosopher and sociologist, best known for furthering the critique of everyday life, for introducing the concepts of the right to the city and the production of social space, and for his work on dialectical materialism, alienation, and criticism of Stalinism, existentialism, and structuralism. In his prolific career, Lefebvre wrote more than sixty books and three hundred articles. He founded or took part in the founding of several intellectual and academic journals such as Philosophies, La Revue Marxiste, Arguments, Socialisme ou Barbarie, and Espaces et Sociétés.

Viện cơ mật
The Viện cơ mật or "Secret Institute" (chữ Nôm: 院機密; chữ Hán: 機密院; French: Conseil privé, Conseil d’État, Chambre haute), established in 1834, was the Privy Council and key mandarin agency of the imperial court of Vietnam's final Nguyễn dynasty at Huế, until the end of the dynasty in 1945.

Privy council
A privy council is a body that advises a head of state, typically, but not always, in the context of a monarchical government. The term "privy" (from French privé) signifies private or secret. Consequently, a privy council, more common in the past, existed as a group of a ruling monarch's most trusted court advisors. Its purpose was to consistently provide confidential advice on matters of state. Despite the abolition of monarchy, some privy councils remained operational, while others were individually disbanded, allowing the monarchical system to continue to exist without a secret crown council.
Massachusetts Democratic Party

The town was settled in the 1730s by English settlers of the Connecticut Colony and was known as Farmingbury. It was renamed as Wolcott after being incorporated in 1796, following the United States' gaining independence. Some early records spell it as Wolcutt.
Ifosfamide
Ifosfamide, sold under the brand name Ifex among others, is a chemotherapy medication used to treat a number of types of cancer. This includes testicular cancer, soft tissue sarcoma, osteosarcoma, bladder cancer, small cell lung cancer, cervical cancer, and ovarian cancer. It is administered by injection into a vein.

Common side effects include hair loss, vomiting, blood in the urine, infections, and kidney problems. Other severe side effects include bone marrow suppression and decreased level of consciousness. Use during pregnancy will likely result in harm to the baby. Ifosfamide is in the alkylating agent and nitrogen mustard family of medications. It works by disrupting the duplication of DNA and the creation of RNA.

Ifosfamide was approved for medical use in the United States in 1987. It is on the World Health Organization's List of Essential Medicines.

Nitrogen mustard
Nitrogen mustards (NMs) are cytotoxic organic compounds with the bis(2-chloroethyl)amino ((ClC2H4)2NR) functional group. Although originally produced as chemical warfare agents, they were the first chemotherapeutic agents for treatment of cancer. Nitrogen mustards are nonspecific DNA alkylating agents.
Springwater Corridor
The Springwater Corridor Trail is a bicycle and pedestrian rail trail in the Portland metropolitan area in Oregon, United States. It follows a former railway line from Boring through Gresham to Portland, where it ends south of the Eastbank Esplanade. Most of the corridor, about 21 miles (34 km) long, consists of paved, off-street trail, though about 1 mile (1.6 km) overlaps city streets in Portland's Sellwood neighborhood. A large segment roughly follows the course of Johnson Creek and crosses it on bridges many times. Much of the corridor was acquired by the City of Portland in 1990; remaining segments were acquired by Metro thereafter.

The trail is part of the Portland area's 40-Mile Loop trail system.  It connects to many adjacent or nearby parks, including Tideman Johnson Natural Area, Powell Butte, and others.

Powell Butte
Powell Butte is an extinct cinder cone butte in Portland, Oregon, United States.  It is part of the Boring Lava Field, which includes more than 80 small volcanic edifices and lava flows in the Portland–Vancouver metropolitan area. The region around Powell Butte has a cool climate, and the butte and its surroundings feature meadows, rivers, and mixed forests. Powell Butte hosts the Powell Butte Nature Park, which includes about 612 acres (2.48 km2) of trails for biking, hiking, and horseback riding.

Powell Butte lies within historic territory of the Confederated Tribes of the Grand Ronde Community of Oregon. The land surrounding the butte has been used for an orchard and dairy farming. Today two underground reservoirs at the Butte each hold 50,000,000 US gallons (190,000,000 L) of fresh water as a primary part of the public water system for Portland and much of the surrounding region.
Amphistereum
Amphistereum is a genus of fungi in the family Auriculariaceae. Species produce cupulate to effused, leathery basidiocarps (fruit bodies) on wood. Microscopically, fruit bodies have a dimitic hyphal system. The genus is currently only known from North and South America.

Auriculariaceae
The Auriculariaceae are a family of fungi in the order Auriculariales. Species within the family were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps (fruit bodies) that produce spores on septate basidia. Around 100 species are known worldwide. All are believed to be saprotrophic, most growing on dead wood. Fruit bodies of several Auricularia species are cultivated for food on a commercial scale, especially in China.
Dream trance
Dream trance is an early subgenre of trance music that peaked prominently on the international dance scene between 1995 and 1998 (colliding with the first time for trance to reach mainstream). The "dream" term has been known to largely influence house music in general, and therefore the subgenre is also known as dream house or dream dance on some occasions.

Today, dream trance is considered to be the first and the most primitive derivative of the progressive house movement that started around 1992. Many psytrance producers emergent at the time (notably Infected Mushroom) were also influenced by it.

Psychedelic trance
Psychedelic trance, psytrance, or psy is a subgenre of trance music characterized by arrangements of rhythms and layered melodies created by high tempo riffs. The genre offers variety in terms of mood, tempo, and style. Some examples include full on, darkpsy, forest, minimal (Zenonesque), hitech psy, progressive, suomi, psy-chill, psycore (fusion of psychedelic trance and hardcore), psybient (fusion of psychedelic trance and ambient), psybreaks, or "adapted" tracks from other music genres. Goa trance preceded psytrance; when digital media became more commonly used, psytrance evolved. Goa continues to develop alongside the other genres.
