Comradeliness is a term used to describe the feeling of camaraderie, friendship, support and understanding that exists among comrades or people who share a common interest, activity or purpose. It typically denotes a strong bond based on mutual respect, loyalty, and shared experiences. It often emerges in settings like the military, workplaces, sports teams, or social and political movements.

Terrestrial Dynamical Time (TDT) is a time scale representing time experienced on the surface of the Earth to a high precision, in terms of atomic time rather than celestial motion. It was used in astronomical computations, primarily for predicting the positions of celestial bodies, until it was replaced by Terrestrial Time. It is used to account for the variances in the Earths rotation, such as irregularities and slowdowns, for more accurate timekeeping. TDT expresses time as counted on the hypothetical, perfectly uniform atomic time scale rather than as observed by an actual observer on the rotating Earth.

Historical linguistics, also termed diachronic linguistics, is the scientific study of language change over time. Principal concerns of historical linguistics include: to describe and account for observed changes in particular languages to reconstruct the pre-history of languages and to determine their relatedness, grouping them into language families (comparative linguistics) to develop general theories about how and why language changes to describe the history of speech communities to study the history of words, i.e. etymology Historical linguistics is founded on the Uniformitarian Principle, which is defined by linguist Donald Ringe as: Unless we can demonstrate significant changes in the conditions of language acquisition and use between some time in the unobservable past and the present, we must assume that the same types and distributions of structures, variation, changes, etc. existed at that time in the past as in the present.

A six-gilled shark refers to any species within the family Hexanchidae, characterized by having six gill slits on each side of their head, a single dorsal fin, and a tail where the upper lobe is markedly longer than the lower lobe. These sharks are primitive, deep-sea species known to be among the largest fish in the world. Examples include the bluntnose sixgill shark and the bigeye sixgill shark.

The Louisiana Purchase (French: Vente de la Louisiane, lit. Sale of Louisiana) was the acquisition of the territory of Louisiana by the United States from the French First Republic in 1803. In return for fifteen million dollars, or approximately eighteen dollars per square mile, the United States nominally acquired a total of 828,000 sq mi (2,140,000 km2; 530,000,000 acres) in Middle America. However, France only controlled a small fraction of this area, most of which was inhabited by Native Americans; effectively, for the majority of the area, the United States bought the preemptive right to obtain Indian lands by treaty or by conquest, to the exclusion of other colonial powers.The Kingdom of France had controlled the Louisiana territory from 1699 until it was ceded to Spain in 1762. In 1800, Napoleon, the First Consul of the French Republic, regained ownership of Louisiana as part of a broader effort to re-establish a French colonial empire in North America. However, Frances failure to suppress a revolt in Saint-Domingue, coupled with the prospect of renewed warfare with the United Kingdom, prompted Napoleon to consider selling Louisiana to the United States. Acquisition of Louisiana was a long-term goal of President Thomas Jefferson, who was especially eager to gain control of the crucial Mississippi River port of New Orleans. Jefferson tasked James Monroe and Robert R. Livingston with purchasing New Orleans. Negotiating with French Treasury Minister François Barbé-Marbois, the American representatives quickly agreed to purchase the entire territory of Louisiana after it was offered. Overcoming the opposition of the Federalist Party, Jefferson and Secretary of State James Madison persuaded Congress to ratify and fund the Louisiana Purchase. The Louisiana Purchase extended United States sovereignty across the Mississippi River, nearly doubling the nominal size of the country. The purchase included land from fifteen present U.S. states and two Canadian provinces, including the entirety of Arkansas, Missouri, Iowa, Oklahoma, Kansas, and Nebraska; large portions of North Dakota and South Dakota; the area of Montana, Wyoming, and Colorado east of the Continental Divide; the portion of Minnesota west of the Mississippi River; the northeastern section of New Mexico; northern portions of Texas; New Orleans and the portions of the present state of Louisiana west of the Mississippi River; and small portions of land within Alberta and Saskatchewan. At the time of the purchase, the territory of Louisianas non-native population was around 60,000 inhabitants, of whom half were enslaved Africans. The western borders of the purchase were later settled by the 1819 Adams–Onís Treaty with Spain, while the northern borders of the purchase were adjusted by the Treaty of 1818 with Britain.

Corydalus is a genus of insects in the family Corydalidae, commonly known as dobsonflies or fishflies. These insects are usually found near bodies of water where their larvae, known as hellgrammites, live.

Boletus frostii is a species of bolete fungus in the family Boletaceae. Native to North America, it has a red cap, red pores and a red or red-dotted stalk. It is named after American biologist Charles Frost. While its known to have a mild taste, it has been reported to cause gastrointestinal symptoms when consumed and is generally considered inedible. This mushroom is often found in a mycorrhizal association with hardwood trees during summer and autumn months.

Deicers usually work by lowering the freezing point of water or by physically breaking up or melting existing ice.

Stonewalling is a refusal to communicate or cooperate. Such behaviour occurs in situations such as marriage guidance counseling, diplomatic negotiations, politics and legal cases. Body language may indicate and reinforce this by avoiding contact and engagement with the other party. People use deflection in a conversation in order to render a conversation pointless and insignificant. Tactics in stonewalling include giving sparse, vague responses, refusing to answer questions, or responding to questions with additional questions. Stonewalling can be used as a stalling tactic rather than an avoidance tactic.
