Schotten–Baumann reaction
The Schotten–Baumann reaction is a method to synthesize amides from amines and acid chlorides:

Schotten–Baumann reaction conditions  can also refer to the formation of esters by reaction of an acyl chloride with a primary or secondary alcohol. The reaction was first described in 1883 by German chemists Carl Schotten and Eugen Baumann.

The name "Schotten–Baumann reaction conditions" often indicate the use of a two-phase solvent system, consisting of water and an organic solvent. The base in the water phase neutralizes the acid generated by the reaction while the starting materials and product remain in the organic phase, often dichloromethane or diethyl ether.

Chemische Berichte
Chemische Berichte (usually abbreviated as Ber. or Chem. Ber.) was a German-language scientific journal of all disciplines of chemistry founded in 1868. It was one of the oldest scientific  journals in chemistry, until it merged with Recueil des Travaux Chimiques des Pays-Bas to form Chemische Berichte/Recueil in 1997. Chemische Berichte/Recueil was then merged with other European journals in 1998 to form European Journal of Inorganic Chemistry.

This is a list of the National Register of Historic Places listings in Camp County, Texas.

This is intended to be a complete list of properties and districts listed on the National Register of Historic Places in Camp County, Texas. There is one district listed in the county. This district also contains Recorded Texas Historic Landmarks.

This National Park Service list is complete through NPS recent listings posted March 21, 2025.

Recorded Texas Historic Landmark
Recorded Texas Historic Landmark (RTHL) is a designation awarded by the Texas Historical Commission for historically and architecturally significant properties in the U.S. state of Texas. RTHL is a legal designation and the highest honor the state can bestow on a historic structure. Purchase and display of a historical marker is a required component of the RTHL designation process. Because it is a legal designation, owners of RTHL-designated structures must give 60 days' notice before any alterations are made to the exterior of the structure. Changes that are unsympathetic may result in removal of the designation and historical marker. More than 3,600 RTHL structures are spread throughout the state.

Districts of South Africa
The nine provinces of South Africa are divided into 52 districts (sing. district, Zulu: isifunda; Xhosa: isithili; Afrikaans: distrikte; Northern Sotho: selete; Tswana: kgaolo; Sotho: setereke; Tsonga: xifundza; Swazi: sigodzi; Venda: tshiṱiriki; Southern Ndebele: isiyingi), which are either metropolitan or district municipalities. They are the second level of administrative division, below the provinces and (in the case of district municipalities) above the local municipalities.

As a consequence of the 12th amendment of the Constitution in December 2005, which altered provincial boundaries, the number of districts was reduced from 53. Another effect of the amendment is that each district is now completely contained within a single province, thus eliminating cross-border districts. The districts also cover the entire area of the continental republic.

Swazi or siSwati is a Bantu language of the Nguni group spoken in Eswatini (formerly Swaziland) and South Africa by the Swati people. The number of speakers is estimated to be in the region of 4.7 million including first and second language speakers. The language is taught in Eswatini and some South African schools in Mpumalanga, particularly former KaNgwane areas. Siswati is an official language of Eswatini (along with English), and is also one of the twelve official languages of South Africa.

The official term is "siSwati" among native speakers; in English, Zulu, Ndebele or Xhosa it may be referred to as Swazi. siSwati is most closely related to the other Tekela languages, like Phuthi and Northern Transvaal (Sumayela) Ndebele, but is also very close to the Zunda languages: Zulu, Southern Ndebele, Northern Ndebele, and Xhosa.

Theta operator
In mathematics, the theta operator is a differential operator defined by

This is sometimes also called the homogeneity operator, because its eigenfunctions are the monomials in z:

In n variables the homogeneity operator is given by

As in one variable, the eigenspaces of θ are the spaces of homogeneous functions. (Euler's homogeneous function theorem)

Eigenfunction
In mathematics, an eigenfunction of a linear operator D defined on some function space is any non-zero function  in that space that, when acted upon by D, is only multiplied by some scaling factor called an eigenvalue. As an equation, this condition can be written as

for some scalar eigenvalue  The solutions to this equation may also be subject to boundary conditions that limit the allowable eigenvalues and eigenfunctions.

An eigenfunction is a type of eigenvector.

World Chlorine Council
The World Chlorine Council (WCC) is an international network of national and regional trade associations representing the chlorine and chlorinated products industries in more than 27 countries. Members include chloralkali process associations such as Euro Chlor, Japan Soda Industry Association, Alkali Manufacturers' Association of India, and RusChlor (Russian Federation). Members from the product sector include five vinyl producer associations, and the Halogenated Solvents Industry Alliance (United States).

Vinyl group
In organic chemistry, a vinyl group (abbr. Vi; IUPAC name: ethenyl group) is a functional group with the formula −CH=CH2.  It is the ethylene (IUPAC name: ethene) molecule (H2C=CH2) with one fewer hydrogen atom.  The name is also used for any compound containing that group, namely R−CH=CH2 where R is any other group of atoms.

An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as vinyl.

Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups. (A styrenic crosslinker with two vinyl groups is called divinyl benzene.)
Heikki Lunta
Heikki Lunta is the personification of the snow god in the folklore of the Upper Peninsula of Michigan, influenced by Finnish mythology.
The character of Heikki Lunta is a product of the heavy Finnish-American presence in the Keweenaw Peninsula of Michigan, paired with a tremendous annual snowfall. The character has become an established part of local culture and media.

Finnish mythology
Finnish mythology commonly refers to the folklore of Finnish paganism, of which a modern revival is practiced by a small percentage of the Finnish people. It has many shared features with Estonian and other Finnic mythologies, but also with neighbouring Baltic, Slavic and, to a lesser extent, Norse mythologies.

Finnish mythology survived within an oral tradition of mythical poem-singing and folklore well into the 19th century.

Of the animals, the most sacred was the bear, whose real name was never uttered out loud, which was thought to be unfavorable to the hunt. The bear (Finnish: karhu) was seen as the embodiment of the forefathers, and for this reason it was called by many circumlocutions: mesikämmen 'mead-paw', otso 'browed one', kontio 'dweller of the land', metsän kultaomena 'the golden apple of the forest'. It was not strictly seen as a god.
