Aryl group
In organic chemistry, an aryl is any functional group or substituent derived from an aromatic ring, usually an aromatic hydrocarbon, such as phenyl and naphthyl. "Aryl" is used for the sake of abbreviation or generalization, and "Ar" is used as a placeholder for the aryl group in chemical structure diagrams, analogous to “R” used for any organic substituent. “Ar” is not to be confused with the elemental symbol for argon.

A simple aryl group is phenyl (C6H5−), a group derived from benzene. Examples of other aryl groups consist of:

The tolyl group (CH3C6H4−) which is derived from toluene (methylbenzene)

The xylyl group ((CH3)2C6H3−), which is derived from xylene (dimethylbenzene)

The naphthyl group (C10H7−), which is derived from naphthalene

Arylation is the process in which an aryl group is attached to a substituent. It is typically achieved by cross-coupling reactions.

Tolyl group
In organic chemistry, tolyl groups are functional groups related to toluene.  They have the general formula CH3C6H4−R. The change of the relative position of the methyl and the R substituent on the aromatic ring can generate three possible structural isomers: 1,2 (ortho), 1,3 (meta), and 1,4 (para). Tolyl groups are aryl groups which are commonly found in the structure of diverse chemical compounds. They are considered nonpolar and hydrophobic groups.

The functionalization to include tolyl groups into compounds is often done by Williamson etherification, using tolyl alcohols as reagents, or by C-C coupling reactions. Tolyl sulfonates are excellent leaving groups in nucleophilic substitutions, for this reason, they are commonly generated as intermediaries to activate alcohols. To this end, 4-toluenesulfonyl chloride is reacted in the presence of a base with the corresponding alcohol.
Karbi-Kuki conflict
The Kuki-Karbi conflict is an ethnic conflict between the Kuki people and Karbi people in the Karbi Anglong district of Assam, India. The conflict has its roots in disputes over land, resources and political representation between the two groups.

Tangram
The tangram (Chinese: 七巧板; pinyin: qīqiǎobǎn; lit. 'seven boards of skill') is a dissection puzzle consisting of seven flat polygons, called tans, which are put together to form shapes. The objective is to replicate a pattern (given only an outline) generally found in a puzzle book using all seven pieces without overlap. Alternatively the tans can be used to create original minimalist designs that are either appreciated for their inherent aesthetic merits or as the basis for challenging others to replicate its outline. It is reputed to have been invented in China sometime around the late 18th century and then carried over to America and Europe by trading ships shortly after. It became very popular in Europe for a time, and then again during World War I. It is one of the most widely recognized dissection puzzles in the world and has been used for various purposes including amusement, art, and education.

Sam Loyd
Samuel Loyd (January 30, 1841 – April 10, 1911) was an American chess player, chess composer, puzzle author, and recreational mathematician. Loyd was born in Philadelphia but raised in New York City.

He succeeded his father, al-Mansur.
Upper American River Project
The Upper American River Project (UARP) is a hydroelectric system operated by the Sacramento Municipal Utility District (SMUD) of Sacramento, California in the United States.

The system consists of 11 dams and eight powerhouses that tap the upper tributaries of the American River drainage in the Sierra Nevada for power generation. Total installed capacity is over 687 MW, producing 1.8 billion KWh annually, enough for 20 percent of the city's electricity needs.

The project mainly utilizes water from the South Fork American River and its tributaries, although some water is drawn from the Rubicon River, a tributary of the Middle Fork American River. Project dams provide water storage of about 430,000 acre⋅ft (530,000 dam3) and a total hydraulic head of 5,417 ft (1,651 m) from the highest reservoir to the lowest powerplant outflow.

South Fork American River
The South Fork American River is a major tributary of the American River in El Dorado County, California, draining a watershed on the western slope of the Sierra Nevada east of Sacramento. The river begins in pristine Desolation Wilderness and flows through the Sierra Nevada foothills. The river at Coloma was the site of James Marshall's discovery of gold at Sutter's Mill on January 24, 1848, which started the California Gold Rush. The South Fork of the American is "the most popular recreation stream in the West" for whitewater rafting in North America, e.g., 80,000 visitors in 2011. Professional whitewater rafting companies have been offering commercial rafting trips on the South Fork American River since 1978.
Board game
A board game is a type of tabletop game that involves small objects (game pieces) that are placed and moved in particular ways on a specially designed patterned game board, potentially including other components, e.g. dice. The earliest known uses of the term "board game" are between the 1840s and 1850s.

While game boards are a necessary and sufficient condition of this genre, card games that do not use a standard deck of cards, as well as games that use neither cards nor a game board, are often colloquially included, with some referring to this genre generally as "table and board games" or simply "tabletop games".

Cooperative board game
Cooperative board games are board games in which players work together to achieve a common goal rather than competing against each other. Either the players win the game by reaching a predetermined objective, or all players lose the game, often by not reaching the objective before a certain event ends the game.
H-IIB
The H-IIB (H2B) was a Japanese expendable launch system jointly developed by JAXA and Mitsubishi Heavy Industries. It was used exclusively to launch the H-II Transfer Vehicle (HTV, or Kōnotori) cargo spacecraft to the International Space Station.

The H-IIB was a two-stage rocket powered by liquid hydrogen and liquid oxygen (hydrolox) engines, with four strap-on solid rocket boosters, and was launched from the Tanegashima Space Center in southern Japan. It could deliver up to 8,000 kg (18,000 lb) to geostationary transfer orbit (GTO), compared with 4,000–6,000 kg (8,800–13,200 lb) for its predecessor, the H-IIA. Its performance to low Earth orbit (LEO) was sufficient to carry the 16,500 kg (36,400 lb) HTV.

The H-IIB made its debut in September 2009 and flew nine times through May 2020, all successfully.

Expendable launch system
An expendable launch system (or expendable launch vehicle/ELV) is a launch vehicle that can be launched only once, after which its components are destroyed during reentry or impact with Earth, or discarded in space. ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed. As of 2024, fewer and fewer satellites and human spacecraft are launched on ELVs in favor of reusable launch vehicles. However, there are many instances where a ELV may still have a compelling use case over a reusable vehicle. ELVs are simpler in design than reusable launch systems and therefore may have a lower production cost. Furthermore, an ELV can use its entire fuel supply to accelerate its payload, offering greater payloads. ELVs are a proven technology in widespread use for many decades.
Kûkherne
Kûkherne (Dutch: Kuikhorne or Kuijkhorne) is a hamlet in the municipalities of Achtkarspelen, Dantumadiel and Tytsjerksteradiel, in the province of Friesland, the Netherlands.

Kuikhorne is relatively large for a hamlet and sometimes it's referred as a village itself. In terms of official address it's divided among four villages; Feanwâlden, De Westereen, Noardburgum and Twijzelerheide.

Tytsjerksteradiel
Tytsjerksteradiel (West Frisian pronunciation: [tiˈtsjɛrkstəraˌdiəl] ⓘ) is a municipality in the province of Friesland in the Netherlands. It is named after the town of Tytsjerk, whose name is derived from a person named Tiete. Tiete was a daughter of Tryn, after whom the region (Trynwâlden) is named. The other villages in Trynwâlden are also named after Tryn's children: Oentsjerk (Oene), Gytsjerk (Giete), Readtsjerk (Reade), Aldtsjerk (Âlde), Ryptsjerk (Rype). A statue of Tryn and her children is placed in Oentsjerk next to the mainroad (Rengerswei). Tsjerk is the West Frisian word for Church. Until 1989 the official name of the municipality was Tietjerksteradeel (pronounced [tiˈtɕɛr(ə)kstəraːˌdeːl] ⓘ), the Dutch name; the current official name is West Frisian.  The largest village in the municipality is Burgum.
