Magic Mirror (Snow White) | The Magic Mirror is a mystical object that is featured in the story of Snow White, depicted as either a hand mirror or a wall-mounted mirror. |
Scorpion sting | A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling. In serious cases, scorpion stings may involve the envenomation of humans by toxic scorpions, which may result in extreme pain, serious illness, or even death depending on the toxicity of the venom.Most scorpion stings range in severity from minor swelling to medically significant lesions, with only a few able to cause severe allergic, neurotic or necrotic reactions. However, scorpion stings account for approximately 3,000 deaths a year worldwide. The Brazilian yellow scorpion (Tityus serrulatus) is one species known for being especially dangerous, being responsible for most scorpion sting fatalities in South America.Scorpion stings are seen all over the world but are predominantly seen in the tropical and subtropical areas. In the Western hemisphere, these areas include Mexico, northern South America and southeast Brazil. In the Eastern hemisphere, these regions include Sub-Saharan Africa, the Middle East, and the Indian subcontinent. |
Sovereign ring | A sovereign ring is a ring which typically has a gold sovereign as a primary decorative feature, with the obverse face as the visible detail. The coin may be either genuine or replica tender, and may be either a sovereign or half sovereign. Sovereign rings are associated with chav culture in the UK, or more broadly with emulating the look of a mafioso.In the United Kingdom it is also common to use custom coinage bearing such motifs as the 'Three Lions' or other similar imagery such as Saint George, or a Welsh Dragon.Celebrities who have been observed wearing a sovereign ring include Brad Pitt, Ghislaine Maxwell and the English rapper Louise Amanda Harman, hence her stage name of "Lady Sovereign". |
Amplitude distortion | Amplitude distortion is distortion occurring in a system, subsystem, or device when the output amplitude is not a linear function of the input amplitude under specified conditions. Generally, output is a linear function of input only for a fixed portion of the transfer characteristics. In this region, Ic=βIb where Ic is collector current and Ib is base current, following linear relation y=mx. |
OrientDB | OrientDB is an open source NoSQL database management system written in Java. It is a Multi-model database, supporting graph, document, key/value, and object models, but the relationships are managed as in graph databases with direct connections between records. It supports schema-less, schema-full and schema-mixed modes. It has a strong security profiling system based on users and roles and supports querying with Gremlin along with SQL extended for graph traversal. OrientDB uses several indexing mechanisms based on B-tree and Extendible hashing, the last one is known as "hash index", there are plans to implement LSM-tree and Fractal tree index based indexes. Each record has Surrogate key which indicates position of record inside of Array list , links between records are stored either as single value of record's position stored inside of referrer or as B-tree of record positions (so-called record IDs or RIDs) which allows fast traversal (with O(1) complexity) of one-to-many relationships and fast addition/removal of new links. OrientDB is the fifth most popular graph database according to the DB-Engines graph database ranking, as of December 2021. The development of OrientDB still relies on an open source community led by OrientDB LTD company created by its original author Luca Garulli. The project uses GitHub to manage the sources, contributors and versioning, Google Group and Stack Overflow to provide free support to the worldwide users. OrientDB also offers a free Udemy course for those hoping to learn the basics and get started with OrientDB. |
Oatmeal ball | The oatmeal ball (Danish: havregrynskugle) or the chocolate ball (Swedish: chokladboll) is a type of unbaked pastry that is a popular Danish and Swedish confectionery. |
Control key | In computing, a Control key Ctrl is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, Ctrl+C). Similarly to the Shift key, the Control key rarely performs any function when pressed by itself. The Control key is located on or near the bottom left side of most keyboards (in accordance with the international standard ISO/IEC 9995-2), with many featuring an additional one at the bottom right. |
Transfer-messenger RNA | Transfer-messenger RNA (abbreviated tmRNA, also known as 10Sa RNA and by its genetic name SsrA) is a bacterial RNA molecule with dual tRNA-like and messenger RNA-like properties. The tmRNA forms a ribonucleoprotein complex (tmRNP) together with Small Protein B (SmpB), Elongation Factor Tu (EF-Tu), and ribosomal protein S1. In trans-translation, tmRNA and its associated proteins bind to bacterial ribosomes which have stalled in the middle of protein biosynthesis, for example when reaching the end of a messenger RNA which has lost its stop codon. The tmRNA is remarkably versatile: it recycles the stalled ribosome, adds a proteolysis-inducing tag to the unfinished polypeptide, and facilitates the degradation of the aberrant messenger RNA. In the majority of bacteria these functions are carried out by standard one-piece tmRNAs. In other bacterial species, a permuted ssrA gene produces a two-piece tmRNA in which two separate RNA chains are joined by base-pairing. |
DYNIX | DYNIX (DYNamic UnIX) was a Unix-like operating system developed by Sequent Computer Systems, based on 4.2BSD and modified to run on Intel-based symmetric multiprocessor hardware. The third major (Dynix 3.0) version was released May, 1987; by 1992 DYNIX was succeeded by DYNIX/ptx, which was based on UNIX System V.IBM obtained rights to DYNIX/ptx in 1999, when it acquired Sequent for $810 million.IBM's subsequent Project Monterey was an attempt, circa 1999, "to unify AIX with Sequent's Dynix/ptx operating system and UnixWare." By 2001, however, "the explosion in popularity of Linux ... prompted IBM to quietly ditch" this.A version was named Dynix 4.1.4. |
Google Pay (payment method) | Google Pay (formerly Android Pay) is a mobile payment service developed by Google to power in-app, online, and in-person contactless purchases on mobile devices, enabling users to make payments with Android phones, tablets, or watches.

ICalendar | The Internet Calendaring and Scheduling Core Object Specification (iCalendar) is a media type which allows users to store and exchange calendaring and scheduling information such as events, to-dos, journal entries, and free/busy information, and together with its associated standards has been a cornerstone of the standardization and interoperability of digital calendars across different vendors. Files formatted according to the specification usually have an extension of .ics. With supporting software, such as an email reader or calendar application, recipients of an iCalendar data file can respond to the sender easily or counter-propose another meeting date/time. The file format is specified in a proposed Internet standard (RFC 5545) for calendar data exchange. The standard and file type are sometimes referred to as "iCal", which was the name of the Apple Inc. calendar program until 2012 (see iCal), which provides one of the implementations of the standard. |
Umbrella title | An umbrella title is a formal or informal name connecting a number of individual items with a common theme. It is most often used in lieu of listing the separate components or providing a convenient "label" for a collection of disciplines. |
Carbon dioxide transmission rate | Carbon dioxide transmission rate (COTR) is the measurement of the amount of carbon dioxide gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description. |

National drug code | The national drug code (NDC) is a unique product identifier used in the United States for drugs intended for human use. The Drug Listing Act of 1972 requires registered drug establishments to provide the Food and Drug Administration (FDA) with a current list of all drugs manufactured, prepared, propagated, compounded, or processed by it for commercial distribution. Drug products are identified and reported using the NDC. |
COVID-19 pandemic in Argentina | The COVID-19 pandemic in Argentina was a part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As of 18 August 2023, a total of 10,044,957 people were confirmed to have been infected, and 130,472 people were known to have died because of the virus.On 3 March 2020, the virus was confirmed to have spread to Argentina. On 7 March 2020, the Ministry of Health confirmed the country's first documented death, a 64-year-old man who had travelled to Paris, France, who also had other health conditions; the case was only confirmed as positive after the patient's demise.On 19 March 2020, a nationwide lockdown was established in Argentina. The lockdown was lifted throughout all the country, excepting the Greater Buenos Aires urban area (where 31.9% of the country's population live), on 10 May, with Greater Buenos Aires locked down until 17 July, where the lockdown was due to be gradually loosened in several stages to lead to the return to normality. However, restrictions were extended several times until 8 November 2020. During the second wave, another nationwide lockdown took place from 22 to 31 May 2021.Responses to the outbreak have included restrictions on commerce and movement, closure of borders, and the closure of schools and educational institutions. Clusters of infections and deaths have occurred in nursing homes, prisons and other detention centers, and urban areas. The number of tests increased over time, although there were some concerns as there was less testing than in other countries of the region such as Chile and Peru. Even so, the government's responses to the pandemic were among the best received by the population in the region during the early stages of the pandemic. |
IA5STRING | A IA5String is a restricted character string type in the ASN.1 notation.
It is used to represent ISO 646 (IA5) characters.
According to the ITU-T Rec. X.680 (ASN.1 Specification of basic notation) the entire character set contains precisely 128 characters.
Those characters are generally equivalent to the first 128 characters of the ASCII alphabet. |
Contralto | A contralto (Italian pronunciation: [konˈtralto]) is a type of classical female singing voice whose vocal range is the lowest female voice type.The contralto's vocal range is fairly rare; similar to the mezzo-soprano, and almost identical to that of a countertenor, typically between the F below middle C (F3 in scientific pitch notation) to the second F above middle C (F5), although, at the extremes, some voices can reach the D below middle C (D3) or the second B♭ above middle C (B♭5). The contralto voice type is generally divided into the coloratura, lyric, and dramatic contralto. |
Flux pumping | Flux pumping is a method for magnetising superconductors to fields in excess of 15 teslas. The method can be applied to any type II superconductor and exploits a fundamental property of superconductors, namely their ability to support and maintain currents on the length scale of the superconductor. Conventional magnetic materials are magnetised on a molecular scale which means that superconductors can maintain a flux density orders of magnitude bigger than conventional materials. Flux pumping is especially significant when one bears in mind that all other methods of magnetising superconductors require application of a magnetic flux density at least as high as the final required field. This is not true of flux pumping. |
Resistojet rocket | A resistojet is a method of spacecraft propulsion (electric propulsion) that provides thrust by heating a typically non-reactive fluid. Heating is usually achieved by sending electricity through a resistor consisting of a hot incandescent filament, with the expanded gas expelled through a conventional nozzle.Resistojets have been flown in space since 1965 on board military Vela satellites. However, they only became used in commercial applications in 1980 with the launch of the first satellites in the INTELSAT-V program. Many GEO spacecraft, and all 95 Iridium, used Aerojet MR-501/MR-502 series resistojet engines. Nowadays resistojet propulsion is used for orbit insertion, attitude control, and deorbit of LEO satellites, and do well in situations where energy is much more plentiful than mass, and where propulsion efficiency needs to be reasonably high but low thrust is acceptable.Resistojets have also been proposed as means of using biowaste as reaction mass, particularly in conjunction with hydrazine. Studies focus on the characteristics of steam and carbon dioxide as major constituents of a biowaste stream, and typically use cubic zirconia as a heating element. |
Ascetical theology | Ascetical theology is the organized study or presentation of spiritual teachings found in Christian Scripture and the Church Fathers that help the faithful to more perfectly follow Christ and attain to Christian perfection. Christian asceticism is commonly thought to imply self-denial for a spiritual purpose. The term ascetical theology is used primarily in Roman Catholic theology; Eastern Orthodox theology carries its own distinct terms and definitions (see below), and other religious traditions conceive of following and conforming to God and Christ differently from either Orthodoxy or Catholicism. |
Diadem (board game) | Diadem is a 1981 board game published by Fantasy Games Unlimited. |
Sakura Pascarelli | Sakura Pascarelli is an Italian physicist and the scientific director at the European XFEL. Her research focuses on the study on matter at extreme conditions of pressure, temperature and magnetic fields, in particular using X-ray absorption spectroscopy (XAS) and X-ray Magnetic Linear and Circular Dichroism (XMCD). |
Steatosis | Steatosis, also called fatty change, is abnormal retention of fat (lipids) within a cell or organ. Steatosis most often affects the liver – the primary organ of lipid metabolism – where the condition is commonly referred to as fatty liver disease. Steatosis can also occur in other organs, including the kidneys, heart, and muscle. When the term is not further specified (as, for example, in 'cardiac steatosis'), it is assumed to refer to the liver.Risk factors associated with steatosis are varied, and may include diabetes mellitus, protein malnutrition, hypertension, cell toxins, obesity, anoxia, and sleep apnea.Steatosis reflects an impairment of the normal processes of synthesis and elimination of triglyceride fat. Excess lipid accumulates in vesicles that displace the cytoplasm. When the vesicles are large enough to distort the nucleus, the condition is known as macrovesicular steatosis; otherwise, the condition is known as microvesicular steatosis. While not particularly detrimental to the cell in mild cases, large accumulations can disrupt cell constituents, and in severe cases the cell may even burst. |

November 1994 lunar eclipse | A penumbral lunar eclipse took place on Friday, November 18, 1994, the second of two lunar eclipses in 1994, the first was a partial lunar eclipse on Wednesday, May 25. This event followed the total solar eclipse of November 3, 1994. |
Streptococcus gordonii | Streptococcus gordonii is a Gram-positive bacterium included among some of the initial colonizers of the periodontal environment. The organism, along with related oral streptococci, has a high affinity for molecules in the salivary pellicle (or coating) on tooth surfaces. S. gordonii therefore can rapidly colonize clean tooth surfaces, and S. gordonii along with related organisms comprise a high percentage, up to 70%, of the bacterial biofilm that forms on clean tooth surfaces. Generally harmless in the mouth, S. gordonii can cause acute bacterial endocarditis upon gaining access systemically. S. gordonii also forms an attachment substratum for later colonizers of tooth surface and can modulate the pathogenicity of these secondary colonizers through interspecies communication mechanisms.The whole genome sequence of S. gordonii CCUG 33482 type strain was deposited and published in DNA Data Bank of Japan, European Nucleotide Archive and GenBank in 2016 under the accession number LQWV00000000. |

InterPlanetary File System | The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting IPFS hosts.IPFS can among others replace the location based hypermedia server protocols http and https to distribute the World Wide Web. |
Electrostatic coating | Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.An addition to the electrostatic coating (or e-coating) process is dipping electrically conductive parts into a tank of paint that is then electrostatically charged. The ionic bond of the paint to the metal creates the paint coating, in which its thickness is directly proportional to the length of time the parts are left in the tank and the time the charge remains active. Once the parts are removed from the paint tank, they are rinsed off to remove any residual paint that is not ionically bonded, leaving a thin film of electrostatically bonded paint on the surface of the part. |
POPLmark challenge | In programming language theory, the POPLmark challenge (from "Principles of Programming Languages benchmark", formerly Mechanized Metatheory for the Masses!) (Aydemir, 2005) is a set of benchmarks designed to evaluate the state of automated reasoning (or mechanization) in the metatheory of programming languages, and to stimulate discussion and collaboration among a diverse cross section of the formal methods community. Very loosely speaking, the challenge is about measurement of how well programs may be proven to match a specification of how they are intended to behave (and the many complex issues that this involves). The challenge was initially proposed by the members of the PL club at the University of Pennsylvania, in association with collaborators around the world. The Workshop on Mechanized Metatheory is the main meeting of researchers participating in the challenge. |
Moodbar | Moodbar is a computer visualization used for navigating within a piece of music or any other recording on a digital audio track. This is done with a commonly horizontal bar that is divided into vertical stripes. Each stripe has a colour combination showing the "mood" within a short part of the audio track. The colour can depend on spectrum and/or rhythmic features of the part of the track. If the audio is a song then various parts of it (intro, choruses, solos, accents etc.) as well as changes (dynamics, rhythm, texture, playing instruments) are differently coloured on the bar. If the audio is a speech or an interview then the moodbar displays different speaking segments in unique colour combinations. Moodbar was originally presented by Gavin Wood and Simon O’Keefe in their paper On Techniques for Content-Based Visual Annotation to Aid Intra-Track Music Navigation.Moodbar has been implemented for Amarok, Clementine, Strawberry Music Player and Exaile music players and the GJay smart playlist creator for Linux. |

He is noted for significant achievements in the fields of osteoarthritis cartilage injury, regenerative therapies and contributions on understanding of joint pathology and repair, the development and validation of equine models of joint diseases, surgical technologies, intra-articular therapies, cartilage resurfacing, tissue engineering and gene therapies for osteoarthritis many of which have been or are translatable to human joint disease. He received the Marshall R. Urist Award for Excellence in Tissue Regeneration Research from the Orthopaedic Research Society in 2014 for these contributions as well as raising many generations of basic and clinical researchers in the field of orthopaedics. |
Pneumatic barrier | A pneumatic barrier is a method to contain oil spills. It is also called a bubble curtain. Air bubbling through a perforated pipe causes an upward water flow that slows the spread of oil. It can also be used to stop fish from entering polluted water. A further application of the pneumatic barrier is to decrease the salt-water exchange in navigation locks and prevent salt intrusion in rivers. |
KvLQT3 | Kv7.3 (KvLQT3) is a potassium channel protein coded for by the gene KCNQ3.It is associated with benign familial neonatal epilepsy. |
QUEL query languages | QUEL is a relational database query language, based on tuple relational calculus, with some similarities to SQL. It was created as a part of the Ingres DBMS effort at University of California, Berkeley, based on Codd's earlier suggested but not implemented Data Sub-Language ALPHA. QUEL was used for a short time in most products based on the freely available Ingres source code, most notably in an implementation called POSTQUEL supported by POSTGRES. As Oracle and DB2 gained market share in the early 1980s, most companies then supporting QUEL moved to SQL instead. QUEL continues to be available as a part of the Ingres DBMS, although no QUEL-specific language enhancements have been added for many years. |
Advanced Graphics Riser | The Advanced Graphics Riser is a variation of the Accelerated Graphics Port (AGP) used in some PCIe motherboards made by MSI to offer a limited backwards compatibility with AGP. It is, effectively, a modified PCIe slot allowing for performance comparable to an AGP 4x/8x slot, but with limited support of AGP cards. The manufacturer has published a non-exhaustive compatibility list of cards and chipsets that work with the modified slot. |
Time-scale calculus | In mathematics, time-scale calculus is a unification of the theory of difference equations with that of differential equations, unifying integral and differential calculus with the calculus of finite differences, offering a formalism for studying hybrid systems. It has applications in any field that requires simultaneous modelling of discrete and continuous data. It gives a new definition of a derivative such that if one differentiates a function defined on the real numbers then the definition is equivalent to standard differentiation, but if one uses a function defined on the integers then it is equivalent to the forward difference operator. |
Briquetage | Briquetage or very coarse pottery (VCP) is a coarse ceramic material used to make evaporation vessels and supporting pillars used in extracting salt from brine or seawater. Thick-walled saltpans were filled with saltwater and heated from below until the water had boiled away and salt was left behind. Often, the bulk of the water would be allowed to evaporate in salterns before the concentrated brine was transferred to a smaller briquetage vessel for final reduction. Once only salt was left, the briquetage vessels would have to be broken to remove the valuable commodity for trade.Broken briquetage material is found at multiple sites from the later Bronze Age in Europe into the medieval period and archaeologists have been able to identify different forms and fabrics of the pottery, allowing trade networks to be identified. Saltworking sites contain large quantities of the orange/red material and in Essex the mounds of briquetage are known as Red Hills. A recent discovery at the Poiana Slatinei archaeological site next to a salt spring in Lunca, Neamt County, Romania, indicates that Neolithic people of the Precucuteni Culture were boiling the salt-laden spring water through the process of Briquetage to extract the salt as far back as 6050 BC, making it perhaps the oldest saltworks in history. |
Eurofruit | Eurofruit (full title Eurofruit Magazine) is a monthly global trade marketing magazine for the European fresh fruit and vegetable sector. |
Foreskin piercing | Foreskin piercing is a piercing that passes through the foreskin of the penis. It is the male equivalent of a clitoral hood piercing in females.
It is a generally fast-healing piercing and involves a relatively simple procedure. The only true requirement is the male must have not been circumcised (or at least have sufficient foreskin left from his circumcision).
Foreskin piercings have been used for male infibulation. |
Game drive system | The game drive system is a hunting strategy in which game are herded into confined or dangerous places where they can be more easily killed. It can also be used for animal capture as well as for hunting, such as for capturing mustangs. The use of the strategy dates back into prehistory. Once a site is identified or manipulated to be used as a game drive site, it may be repeatedly used over many years. Examples include buffalo jumps and desert kites. |
Compound of two tetrahedra | In geometry, a compound of two tetrahedra is constructed by two overlapping tetrahedra, usually implied as regular tetrahedra. |
JFace | JFace is defined by the Eclipse project as "a UI toolkit that provides helper classes for developing UI features that can be tedious to implement." The Standard Widget Toolkit (SWT) is an open source widget toolkit for Java designed to provide efficient, portable access to the user-interface facilities of the operating systems on which it is implemented. |
Smooth curve hull | Smooth curve hulls are hulls that are rounded and do not usually have any chines or corners. They can be moulded, round-bilged or soft-chined. Examples are the round bilge, semi-round bilge and s-bottom hull. |
Serotonin antagonist and reuptake inhibitor | Serotonin antagonist and reuptake inhibitors (SARIs) are a class of drugs used mainly as antidepressants, but also as anxiolytics and hypnotics. They act by antagonizing serotonin receptors such as 5-HT2A and inhibiting the reuptake of serotonin, norepinephrine, and/or dopamine. Additionally, most also antagonize α1-adrenergic receptors. The majority of the currently marketed SARIs belong to the phenylpiperazine class of compounds. |
(3,5-dihydroxyphenyl)acetyl-CoA 1,2-dioxygenase | (3,5-dihydroxyphenyl)acetyl-CoA 1,2-dioxygenase (EC 1.13.11.80, DpgC) is an enzyme catalyses the following chemical reaction (3,5-dihydroxyphenyl)acetyl-CoA + O2 ⇌ 2-(3,5-dihydroxyphenyl)-2-oxoacetate + CoA.This enzyme is involved in the biosynthesis of the nonproteinogenic amino acid (S)-3,5-dihydroxyphenylglycine (Dpg) responsible of the production of vancomycin and teicoplanin antibiotics. It catalyzes the unusual conversion 3,5-dihydroxyphenylacetyl-CoA (DPA-CoA) to 3,5-dihydroxyphenylglyoxylate. |
Current collector | A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and EMUs to carry electric power (current) from overhead lines, electric third rails, or ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies.
Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor.
The current collector arms are electrically conductive but mounted insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or motor. The steel rails of the tracks act as the electrical return. |
Boron tribromide | Boron tribromide, BBr3, is a colorless, fuming liquid compound containing boron and bromine. Commercial samples usually are amber to red/brown, due to weak bromine contamination. It is decomposed by water and alcohols. |
Midgut | The midgut is the portion of the human embryo from which most of the intestines develop. After it bends around the superior mesenteric artery, it is called the "midgut loop". It comprises the portion of the alimentary canal from the end of the foregut at the opening of the bile duct to the hindgut, about two-thirds of the way through the transverse colon. |
Grigore Roșu | Grigore Roșu is a computer science professor at the University of Illinois at Urbana-Champaign and a researcher in the Information Trust Institute. He is known for his contributions in runtime verification, the K framework, matching logic, and automated coinduction. |
Isoborneol | Isoborneol is a bicyclic organic compound and a terpene derivative. The hydroxyl group in this compound is placed in an exo position. The endo diastereomer is called borneol. Being chiral, isoborneol exists as enantiomers. |
Stratified sampling | In statistics, stratified sampling is a method of sampling from a population which can be partitioned into subpopulations. |
Hadacidin | Hadacidin, and hadacidin analogues, have anticancer activity and activity against adenylosuccinate synthetase.Hadacidin is the simplest known naturally occurring hydroxamic acid. The hydroxylamino group is frequently donated by a hydroxylamino acid such as 8-N-hydroxyornithine of the siderochromes. This compound, first isolated and characterized by Kaczka et al. in 1962, seemed well suited for a study of the route of hydroxamic acid biosynthesis. The hydroxamate bond may be considered to be a peptide bond with an oxygen atom on the amide nitrogen, but there is no a priori reason to decide whether the oxygen atom is introduced before or after the formation of the amide bond. In the latter case, formylglycine would be an intermediate in hadacidin biosynthesis. N-Hydroxylation of an amide bond was reported by Cramer et al. (1960), who found that N-hydroxy-2-acetylaminofluorene was formed in the intact rat upon administration of 2-acetylaminofluorene. Nevertheless, this finding cannot be considered direct proof of N-hydroxylation of an amide bond because, as the authors point out, the acetyl group is labile in their experiments, and hydroxylation of the amino group might have occurred. |
Soybean meal | Soybean meal is used in food and animal feeds, principally as a protein supplement, but also as a source of metabolizable energy. Typically 1 bushel (i.e. 60 lbs. or 27.2 kg) of soybeans yields 48 lbs. (21.8 kg) of soybean meal. Soybean meal is produced as a co-product of soybean oil extraction. Some, but not all, soybean meal contains ground soybean hulls. Soybean meal is heat-treated during production, to denature the trypsin inhibitors of soybeans, which would otherwise interfere with protein digestion. |
2-2-2-2 | Under the Whyte notation for the classification of steam locomotives, 2-2-2-2 could represent either the wheel arrangement of two leading wheels, four powered but uncoupled driving wheels, and two trailing wheels; or of two independent leading axles (not in a bogie truck), two driving wheels, and two trailing wheels. |

Neck corset | A neck corset (sometimes called corset collar or neck lacer) is a type of BDSM collar. Unlike a normal corset which compresses the waist, a neck corset is usually not used to compress the neck, except in breathplay. It may act as a posture collar that incorporates stays.
Neck corsets may be worn in BDSM and goth subcultures, and may be worn in a decorative fashion or as a form of fetish clothing. |
Slice preparation | The slice preparation or brain slice is a laboratory technique in electrophysiology that allows the study of neurons from various brain regions in isolation from the rest of the brain, in an ex-vivo condition. Brain tissue is initially sliced via a tissue slicer then immersed in artificial cerebrospinal fluid (aCSF) for stimulation and/or recording. The technique allows for greater experimental control, through elimination of the effects of the rest of the brain on the circuit of interest, careful control of the physiological conditions through perfusion of substrates through the incubation fluid, to precise manipulation of neurotransmitter activity through perfusion of agonists and antagonists. However, the increase in control comes with a decrease in the ease with which the results can be applied to the whole neural system. |
Biotheology | Biotheology is the synthetic application of understanding of biology to the understanding of God, synthesizing modern biology and traditional religious doctrines.Scripturally, Biotheology is motivated by, amongst other things, Saint Paul's exposition of the Church as the Body of Christ, likening its form and functions to the form and functions of the human body (1 Cor. 12:12-17), his remarks in Romans (Ro. 1:20), and Jesus' many parables concerning nature. |
Peixinhos da horta | Peixinhos da horta ([pɐjˈʃĩɲuʒ ðɐ ˈɔɾtɐ]) is a traditional dish in Portuguese cuisine. The name of the dish is literally translated as "Little fishes from the garden", as it resembles small pieces of colorful fish. It was introduced to Japan by Portuguese sailors Antonio da Mota, Francisco Zeimoto and Antonio Peixoto in the sixteenth century, where it was eventually developed into tempura. In 1543, or later, by the Portuguese missionaries that came to them during the 16th century. The peixinhos da horta (green beans) gave rise to tempura, a typical Japanese dish. |

Finite pointset method | In applied mathematics, the name finite pointset method is a general approach for the numerical solution of problems in continuum mechanics, such as the simulation of fluid flows. In this approach (often abbreviated as FPM) the medium is represented by a finite set of points, each endowed with the relevant local properties of the medium such as density, velocity, pressure, and temperature.The sampling points can move with the medium, as in the Lagrangian approach to fluid dynamics or they may be fixed in space while the medium flows through them, as in the Eulerian approach. A mixed Lagrangian-Eulerian approach may also be used. The Lagrangian approach is also known (especially in the computer graphics field) as particle method. |
Equal detour point | The equal detour point is a triangle center with the Kimberling number X(176). It is characterized by the equal detour property, that is if you travel from any vertex of a triangle ABC to another by taking a detour through some inner point P then the additional distance travelled is constant. This means the following equation has to hold: |AP|+|PC|−|AC|=|AP|+|PB|−|AB|=|BP|+|PC|−|BC|. |
Photoactive yellow protein | In molecular biology, the PYP domain (photoactive yellow protein) is a p-coumaric acid-binding protein domain. They are present in various proteins in bacteria.

Digital released OS/8 images for non-commercial purposes which can be emulated through SIMH. |
Hyperfocal distance | In optics and photography, hyperfocal distance is a distance beyond which all objects can be brought into an "acceptable" focus. As the hyperfocal distance is the focus distance giving the maximum depth of field, it is the most desirable distance to set the focus of a fixed-focus camera. The hyperfocal distance is entirely dependent upon what level of sharpness is considered to be acceptable. |

Quintessence (physics) | In physics, quintessence is a hypothetical form of dark energy, more precisely a scalar field, postulated as an explanation of the observation of an accelerating rate of expansion of the universe. The first example of this scenario was proposed by Ratra and Peebles (1988) and Wetterich (1988). The concept was expanded to more general types of time-varying dark energy, and the term "quintessence" was first introduced in a 1998 paper by Robert R. Caldwell, Rahul Dave and Paul Steinhardt. It has been proposed by some physicists to be a fifth fundamental force. Quintessence differs from the cosmological constant explanation of dark energy in that it is dynamic; that is, it changes over time, unlike the cosmological constant which, by definition, does not change. Quintessence can be either attractive or repulsive depending on the ratio of its kinetic and potential energy. Those working with this postulate believe that quintessence became repulsive about ten billion years ago, about 3.5 billion years after the Big Bang.A group of researchers argued in 2021 that observations of the Hubble tension may imply that only quintessence models with a nonzero coupling constant are viable. |
Carter–Goddard–Malrieu–Trinquier model | The Carter–Goddard–Malrieu–Trinquier model (better known as CGMT model) is a model in inorganic chemistry, used for the description and prediction of distortions in multiple bonding systems of main group elements. |
Canal Safety Gates | Canal safety gates or canal air raid protection gates are structures that were installed on canals specifically to reduce or prevent flood damage to dwellings, factories, etc. in the event of aqueducts, canal banks, etc. being breached either through natural events or by enemy action during wars, insurgency, sabotage, etc. They sometimes have a secondary function in regard of canal maintenance work. Substantial structures or simple 'stop gates' or 'stop planks' were used to prevent flooding and were usually only put in place when air raid warnings were given. |
Demand sensing | Demand sensing is a forecasting method that uses artificial intelligence and real-time data capture to create a forecast of demand based on the current realities of the supply chain. Traditionally, forecasting accuracy was based on time series techniques which create a forecast based on prior sales history and draws on several years of data to provide insights into predictable seasonal patterns. Demand sensing uses a broader range of demand signals, (including current data from the supply chain) and different mathematics to create a forecast that responds to real-world events such as market shifts, weather changes, natural disasters and changes in consumer buying behavior. |
2-satisfiability | In computer science, 2-satisfiability, 2-SAT or just 2SAT is a computational problem of assigning values to variables, each of which has two possible values, in order to satisfy a system of constraints on pairs of variables. It is a special case of the general Boolean satisfiability problem, which can involve constraints on more than two variables, and of constraint satisfaction problems, which can allow more than two choices for the value of each variable. But in contrast to those more general problems, which are NP-complete, 2-satisfiability can be solved in polynomial time. |
Transposition (logic) | In propositional logic, transposition is a valid rule of replacement that permits one to switch the antecedent with the consequent of a conditional statement in a logical proof if they are also both negated. It is the inference from the truth of "A implies B" to the truth of "Not-B implies not-A", and conversely. It is very closely related to the rule of inference modus tollens. It is the rule that where " ⇔ " is a metalogical symbol representing "can be replaced in a proof with". |

Metre sea water | The metre (or meter) sea water (msw) is a metric unit of pressure used in underwater diving. It is defined as one tenth of a bar.The unit used in the US is the foot sea water (fsw), based on standard gravity and a sea-water density of 64 lb/ft3. According to the US Navy Diving Manual, one fsw equals 0.30643 msw, 0.030643 bar, or 0.44444 psi, though elsewhere it states that 33 fsw is 14.7 psi (one atmosphere), which gives one fsw equal to about 0.445 psi.The msw and fsw are the conventional units for measurement of diver pressure exposure used in decompression tables and the unit of calibration for pneumofathometers and hyperbaric chamber pressure gauges. |
