Pneumatolysis is an obsolete geologic term for magma emitting gasses that alter surrounding rock or crystallize minerals. [1] Pneumatolysis is now considered a type of hydrothermal interaction.
Conjunction introduction is a valid rule of inference of propositional logic. The rule makes it possible to introduce a conjunction into a logical proof. It is the inference that if the proposition is true, and the proposition is true, then the logical conjunction of the two propositions and is true. For example, if it is true that "it is raining", and it is true that "the cat is inside", then it is true that "it is raining and the cat is inside". The rule can be stated:
The field of strength of materials typically refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus, and Poisson's ratio. In addition, the mechanical element's macroscopic properties such as its length, width, thickness, boundary constraints and abrupt changes in geometry such as holes are considered.
Stepan Prokopovich Timoshenko, later known as Stephen Timoshenko, was an ethnic Ukrainian, citizen of the Russian Empire and later, an American engineer and academician.

A movement is a self-contained part of a musical composition or musical form. While individual or selected movements from a composition are sometimes performed separately as stand-alone pieces, a performance of the complete work requires all the movements to be performed in succession. A movement is a section, "a major structural unit perceived as the result of the coincidence of relatively large numbers of structural phenomena".
A unit of a larger work that may stand by itself as a complete composition. Such divisions are usually self-contained. Most often the sequence of movements is arranged fast-slow-fast or in some other order that provides contrast.
While the ultimate harmonic goal of a tonal composition is the final tonic triad, there will also be many interior harmonic goals found within the piece, some of them tonic triads and some of them not. ...We use the term cadence to mean a harmonic goal, specifically the chords used at the goal.
Uridine-5′-triphosphate (UTP) is a pyrimidine nucleoside triphosphate, consisting of the organic base uracil linked to the 1′ carbon of the ribose sugar, and esterified with tri-phosphoric acid at the 5′ position. Its main role is as substrate for the synthesis of RNA during transcription. UTP is the precursor for the production of CTP via CTP synthetase. UTP can be biosynthesized from UDP by Nucleoside Diphosphate Kinase after using the phosphate group from ATP. UDP + ATP ⇌ UTP + ADP; both UTP and ATP are energetically equal.
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed of the object changes, the kinetic energy of the object also changes. In all real systems, however, nonconservative forces, such as frictional forces, will be present, but if they are of negligible magnitude, the mechanical energy changes little and its conservation is a useful approximation. In elastic collisions, the kinetic energy is conserved, but in inelastic collisions some mechanical energy may be converted into thermal energy. The equivalence between lost mechanical energy and an increase in temperature was discovered by James Prescott Joule.
Dorothy Hill, was an Australian geologist and palaeontologist, the first female professor at an Australian university, and the first female president of the Australian Academy of Science.
Osteolepis is an extinct genus of lobe-finned fish from the Devonian period. It lived in the Lake Orcadie of northern Scotland.
Introduction to Algorithms is a book on computer programming by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein. The book has been widely used as the textbook for algorithms courses at many universities and is commonly cited as a reference for algorithms in published papers, with over 10,000 citations documented on CiteSeerX, and over 67,000 citation on Google Scholar as of 2023. The book sold half a million copies during its first 20 years, and surpassed a million copies sold in 2022. Its fame has led to the common use of the abbreviation "CLRS", or, in the first edition, "CLR".
Goodman & Gilman's The Pharmacological Basis of Therapeutics, commonly referred to as the Blue Bible or Goodman & Gilman, is a textbook of pharmacology originally authored by Louis S. Goodman and Alfred Gilman. First published in 1941, the book is in its 14th edition, and has the reputation of being the "bible of pharmacology". The readership of this book include physicians of all therapeutic and surgical specialties, clinical pharmacologists, clinical research professionals and pharmacists.
Placochelys is an extinct genus of placodont reptiles erected by Otto Jaekel in 1902.
Raymond Cecil Moore was an American geologist and paleontologist. He is known for his work on Paleozoic crinoids, bryozoans, and corals. Moore was a member of US Geological Survey from 1913 until 1949. In 1919 he became professor at the University of Kansas (Lawrence). In 1953 Professor Moore organized the launch and became the first editor of the still ongoing multi-volume work Treatise on Invertebrate Paleontology. Contributors to the Treatise have included the world's specialists in the field. He served as president of the Geological Society of America in 1958. In 1970 he was awarded the Mary Clark Thompson Medal from the National Academy of Sciences.
Stephen L. Harris was Professor of Humanities and Religious Studies at California State University, Sacramento. He served there ten years as department chair and was named a Woodrow Wilson Fellow. He received his MA and PhD degrees from Cornell University. Harris was a member of the American Academy of Religion, a fellow at the Westar Institute, a fellow of the Jesus Seminar, and authored several books on religion, some of which are used in introductory university courses.
In geology, a platform is a continental area covered by relatively flat or gently tilted, mainly sedimentary strata, which overlie a basement of consolidated igneous or metamorphic rocks of an earlier deformation. Platforms, shields and the basement rocks together constitute cratons. Platform sediments can be classified into the following groups: a "protoplatform" of metamorphosed sediments at the bottom, a "quasiplatform" of slightly deformed sediments, a "cataplatform", and an "orthoplatform" at the top. The Mesoproterozoic Jotnian sediments of the Baltic area are examples of a "quasiplatform". The post-Ordovician rocks of the South American Platform are examples of an orthoplatform.
A shingle beach, also known as either a cobble beach or gravel beach, is a commonly narrow beach that is composed of coarse, loose, well-rounded, and waterworn gravel, called shingle. The gravel (shingle) typically consists of smooth, spheroidal to flattened, pebbles, cobbles, and sometimes small boulders, generally in the 20 to 200 millimetres size range. Shingle beaches typically have a steep slope on both their landward and seaward sides. Shingle beaches form in wave-dominated locations where resistant bedrock cliffs provide gravel-sized rock debris. They are also found in high latitudes and temperate shores where the erosion of Quaternary glacial deposits provide gravel-size rock fragments. This term is most widely used in Great Britain.
Gnathophyma involves swelling of the chin. It is a type of lesion associated with rosacea, a common chronic inflammatory skin disorder of the sebaceous glands characterized by redness, swelling, and acne-like pustules.
