Johann Friedrich Gmelin was a German naturalist, chemist, botanist, entomologist, herpetologist, and malacologist.
The metabolic theory of ecology (MTE) is the ecological component of the more general Metabolic Scaling Theory and Kleiber's law. It posits that the metabolic rate of organisms is the fundamental biological rate that governs most observed patterns in ecology. MTE is part of a larger set of theory known as metabolic scaling theory that attempts to provide a unified theory for the importance of metabolism in driving pattern and process in biology from the level of cells all the way to the biosphere.
The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups. In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step. As such, there is no obvious retron for this reaction. The reaction was reported by Nikolai Kischner in 1911 and Ludwig Wolff in 1912.
Perimysium is a sheath of dense irregular connective tissue that groups muscle fibers into bundles or fascicles.
Tobias Jonathan Ansell Wolff is an American short story writer, memoirist, novelist, and teacher of creative writing. He is known for his memoirs, particularly This Boy's Life (1989) and In Pharaoh's Army (1994). He has written four short story collections and two novels including The Barracks Thief (1984), which won the PEN/Faulkner Award for Fiction. Wolff received a National Medal of Arts from President Barack Obama in September 2015.
Maria Barbara Bach was a German singer and the first wife of composer Johann Sebastian Bach. She was also the daughter of his father's cousin Johann Michael Bach.
Siouan or Siouan–Catawban is a language family of North America that is located primarily in the Great Plains, Ohio and Mississippi valleys and southeastern North America with a few other languages in the east.
In organic chemistry, the Arndt–Eistert reaction is the conversion of a carboxylic acid to its homologue. Named for the German chemists Fritz Arndt (1885–1969) and Bernd Eistert (1902–1978), the method entails treating an acid chlorides with diazomethane. It is a popular method of producing β-amino acids from α-amino acids.
The Wolff rearrangement is a reaction in organic chemistry in which an α-diazocarbonyl compound is converted into a ketene by loss of dinitrogen with accompanying 1,2-rearrangement. The Wolff rearrangement yields a ketene as an intermediate product, which can undergo nucleophilic attack with weakly acidic nucleophiles such as water, alcohols, and amines, to generate carboxylic acid derivatives or undergo [2+2] cycloaddition reactions to form four-membered rings. The mechanism of the Wolff rearrangement has been the subject of debate since its first use. No single mechanism sufficiently describes the reaction, and there are often competing concerted and carbene-mediated pathways; for simplicity, only the textbook, concerted mechanism is shown below. The reaction was discovered by Ludwig Wolff in 1902. The Wolff rearrangement has great synthetic utility due to the accessibility of α-diazocarbonyl compounds, variety of reactions from the ketene intermediate, and stereochemical retention of the migrating group. However, the Wolff rearrangement has limitations due to the highly reactive nature of α-diazocarbonyl compounds, which can undergo a variety of competing reactions.
The family Archeocrypticidae is a small group of beetles with no vernacular common name, though recent authors have coined the name cryptic fungus beetles. Adults and larvae seems to be saprophagous and are often found in plant litter. Worldwide, about 10 genera and 50 species are found, most species are pantropical. Enneboeus caseyi has been recorded from the American South, Central America, and Mexico. About 20 species are found in Australia, in the genera Enneboeus,Australenneboeus and Gondwanenneboeus,Archeocrypticus,Falsoplatydema, Nothenneboeus, Sivacrypticus and Wattianus. They are largely absent from the Palearctic and Nearctic regions.
Richard David Wolff is an American Marxian economist known for his work on economic methodology and class analysis. He is a professor emeritus of economics at the University of Massachusetts Amherst and a visiting professor in the graduate program in international affairs of the New School. Wolff has also taught economics at Yale University, City University of New York, University of Utah, University of Paris I (Sorbonne), and The Brecht Forum in New York City.
Sanicula is a genus of plants in family Apiaceae, the same family to which the carrot and parsnip belong. This genus has about 45 species worldwide, with at least 22 in North America. The common names usually include the terms sanicle or black snakeroot.
Niphogeton is a genus of flowering plant in the family Apiaceae.
Joseph "Krystel" Franz Freiherr von Jacquin or Baron Joseph von Jacquin was an Austrian scientist who studied medicine, chemistry, zoology and botany. The standard author abbreviation J.Jacq. is used to indicate this person as the author when citing a botanical name.
Michael Wolff is an American journalist, as well as a columnist and contributor to USA Today, The Hollywood Reporter, and the UK edition of GQ. He has received two National Magazine Awards, a Mirror Award, and has authored seven books, including Burn Rate (1998) about his own dot-com company, and The Man Who Owns the News (2008), a biography of Rupert Murdoch. He co-founded the news aggregation website Newser and is a former editor of Adweek.
Torger Christian "Toto" Wolff is an Austrian billionaire motorsport executive, investor and former racing driver. He holds a 33% stake in the Mercedes-AMG Petronas F1 Team and is Team Principal and CEO of the team.
Augustus Busck was a Danish-American entomologist with the United States Department of Agriculture's Bureau of Entomology. He is best known for his work with microlepidoptera, of which he described over 600 species. His collections of Lepidoptera from North America and the Panama Canal Zone are held by the National Museum of Natural History in Washington, D.C.
This is an overview of the postage stamps and postal history of the Free City of Danzig .
Stage 10 of the Cambrian is the still unnamed third and final stage of the Furongian series. It follows the Jiangshanian and precedes the Ordovician Tremadocian Stage. The proposed lower boundary is the first appearance of the trilobite Lotagnostus americanus around 489.5 million years ago, but other fossils are also being discussed. The upper boundary is defined as the appearance of the conodont Iapetognathus fluctivagus which marks the beginning of the Tremadocian and is radiometrically dated as 485.4 million years ago.
Fire and Fury: Inside the Trump White House is a 2018 book by journalist Michael Wolff which according to Wolff, details the behavior of U.S. President Donald Trump, the staff of his 2016 presidential campaign, and the White House staff. The title refers to a quote by Trump about the conflict with North Korea. The book became a New York Times number one bestseller. Reviewers generally accepted Wolff's portrait of a dysfunctional Trump administration, but were skeptical of many of Wolff's particular claims.
