Squonk
The squonk is a mythical creature that is reputed to live in the hemlock forests of northern Pennsylvania in the United States. Origins Although the earliest written account of the squonk was from the 1910 book '' Fearsome Creatures of the Lumberwoods'', there are no records of the tale being told in Pennsylvania before the book's publication. The next written iteration, from the 1939 book ''Fearsome Critters'', suggested that the creatures had migrated from deserts to swamps to finally settle in Pennsylvania. As logging camps were continuously moving in the early 20th century, this could explain the "creature's" migration to Pennsylvania. Appearance and behavior Unlike many mythological creatures, the supposed physical characteristics of the squonk remain unchanged from the original written account, which states: Later retellings included that squonks were slowest on moonlit nights as they try to avoid seeing its ugly appearance in any illuminated bodies of water.

Fearsome Creatures Of The Lumberwoods
''Fearsome Creatures of the Lumberwoods, With a Few Desert and Mountain Beasts'' is a 1910 fantasy field guide by William Thomas Cox (1878–1961), Minnesota’s first State Forester and Commissioner of Conservation, with illustrations by Coert du Bois (1881–1960; US Consul and forester) and Latin classifications by George Bishop Sudworth (1862–1927; Chief Dendrologist of the Forest Service.) The text is a noteworthy resource on folklore, as a century after its initial publication ''Fearsome Creatures'' remains one of the principal sources on legendary creatures of the United States and Canada. Summary The book presents various sketches of fearsome critters from North American folklore, with descriptions by Cox preceded by full-page landscape illustrations by du Bois. Like in a traditional field guide, each animal is assigned a Latin classification (by Sudworth), afterward noting their habitat, physical makeup, and behavior. At the end of each account; however, there i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polymerization
In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer, monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize them. In chemical compounds, polymerization can occur via a variety of reaction mechanisms that vary in complexity due to the functional groups present in the reactants and their inherent steric effects. In more straightforward polymerizations, alkenes form polymers through relatively simple free-radical reaction, radical reactions; in contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactants polymerize. Alkanes can also be polymerized, but only with the help of strong acids. As alkenes can polymerize in somewhat straightforward radical reactions, they form useful compounds such as polyethylene and p ...

Moiety (chemistry)
In organic chemistry, a moiety ( ) is a part of a molecule that is given a name because it is identified as a part of other molecules as well. Typically, the term is used to describe the larger and characteristic parts of organic molecules, and it should not be used to describe or name smaller functional groups of atoms that chemically react in similar ways in most molecules that contain them. Occasionally, a moiety may contain smaller moieties and functional groups. A moiety that acts as a branch extending from the backbone of a hydrocarbon molecule is called a substituent or side chain, which typically can be removed from the molecule and substituted with others. Active moiety In pharmacology, an active moiety is the part of a molecule or ion – excluding appended inactive portions – that is responsible for the physiological or pharmacological action of a drug substance. Inactive appended portions of the drug substance may include either the alcohol or acid moiety of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboxylic Acid
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group () attached to an R-group. The general formula of a carboxylic acid is or , with R referring to the alkyl, alkenyl, aryl, or other group. Carboxylic acids occur widely. Important examples include the amino acids and fatty acids. Deprotonation of a carboxylic acid gives a carboxylate anion. Examples and nomenclature Carboxylic acids are commonly identified by their trivial names. They at oftentimes have the suffix ''-ic acid''. IUPAC-recommended names also exist; in this system, carboxylic acids have an ''-oic acid'' suffix. For example, butyric acid (C3H7CO2H) is butanoic acid by IUPAC guidelines. For nomenclature of complex molecules containing a carboxylic acid, the carboxyl can be considered position one of the parent chain even if there are other substituents, such as 3-chloropropanoic acid. Alternately, it can be named as a "carboxy" or "carboxylic acid" substituent on another ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecule
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and ''molecule'' is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term ''molecule'' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not consid ...

Decomposition
Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere. Bodies of living organisms begin to decompose shortly after death. Animals, such as worms, also help decompose the organic materials. Organisms that do this are known as decomposers or detritivores. Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition. The science which studies decomposition is generally referred to as ''taphonomy'' from the Greek word ''taphos'', meaning tomb. Decomposition can also be a gradual process for organisms that have extended periods of dormancy. One can differentiate abiotic decomposition from biotic decomposition (biodegradation). The former means "the degradation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Folklore
American folklore encompasses the folklores that have evolved in the present-day United States since Europeans arrived in the 16th century. While it contains much in the way of Native American tradition, it is not wholly identical to the tribal beliefs of any community of native people. Folklore consists of legends, music, oral history, proverbs, jokes, popular beliefs, fairy tales, stories, tall tales, and customs that are the traditions of a culture, subculture, or group. It is also the set of practices through which those expressive genres are shared. Native American folklore Native American cultures are rich in myths and legends that explain natural phenomena and the relationship between humans and the spirit world. According to Barre Toelken, feathers, beadwork, dance steps and music, the events in a story, the shape of a dwelling, or items of traditional food can be viewed as icons of cultural meaning.Toelken, Barrebr>''The Anguish of Snails'', Utah State University Press ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
