Kuso Miso Technique | Kuso Miso Technique (Japanese: くそみそテクニック) is a Japanese gay manga one-shot written and illustrated by Junichi Yamakawa. It was originally published in 1987 in Bara-Komi, a manga supplement of the gay men's magazine Barazoku. The manga depicts a sexual encounter between two men in a public restroom that is complicated by the need of one of the men to relieve himself. Published in Bara-Komi to relative obscurity, Kuso Miso Technique gained notoriety as an Internet meme in the early 2000s after scanned copies of the manga were posted on Japanese imageboards and online forums. |
Separation of concerns | In computer science, separation of concerns is a design principle for separating a computer program into distinct sections. Each section addresses a separate concern, a set of information that affects the code of a computer program. A concern can be as general as "the details of the hardware for an application", or as specific as "the name of which class to instantiate". A program that embodies SoC well is called a modular program. Modularity, and hence separation of concerns, is achieved by encapsulating information inside a section of code that has a well-defined interface. Encapsulation is a means of information hiding. Layered designs in information systems are another embodiment of separation of concerns (e.g., presentation layer, business logic layer, data access layer, persistence layer).Separation of concerns results in more degrees of freedom for some aspect of the program's design, deployment, or usage. Common among these is increased freedom for simplification and maintenance of code. When concerns are well-separated, there are more opportunities for module upgrade, reuse, and independent development. Hiding the implementation details of modules behind an interface enables improving or modifying a single concern's section of code without having to know the details of other sections and without having to make corresponding changes to those other sections. Modules can also expose different versions of an interface, which increases the freedom to upgrade a complex system in piecemeal fashion without interim loss of functionality.Separation of concerns is a form of abstraction. As with most abstractions, separating concerns means adding additional code interfaces, generally creating more code to be executed. So despite the many benefits of well-separated concerns, there is often an associated execution penalty. |
Upshaw–Schulman syndrome | Upshaw–Schulman syndrome (USS) is the recessively inherited form of thrombotic thrombocytopenic purpura (TTP), a rare and complex blood coagulation disease. USS is caused by the absence of the ADAMTS13 protease resulting in the persistence of ultra large von Willebrand factor multimers (ULVWF), causing episodes of acute thrombotic microangiopathy with disseminated multiple small vessel obstructions. These obstructions deprive downstream tissues from blood and oxygen, which can result in tissue damage and death. The presentation of an acute USS episode is variable but usually associated with thrombocytopenia, microangiopathic hemolytic anemia (MAHA) with schistocytes on the peripheral blood smear, fever and signs of ischemic organ damage in the brain, kidney and heart. |
Six Avoidances (Chinese Music) | In Chinese traditional culture, regarding playing Gu-qin, the player should avoid six kinds of occasions: Avoid the time of learning of someone's death; Avoid the time of crying sorrowfully; Avoid the time of being busy with something else; Avoid the time of being angry; Avoid the time of sex; Avoid the time of astonishment. |

It is one of the four main types of vinegars in the Philippines, along with coconut vinegar, cane vinegar, and kaong palm vinegar. It is usually sold under the generic label of "palm vinegar".Nipa palm vinegar is listed in the Ark of Taste international catalogue of endangered heritage foods by the Slow Food movement. Along with other traditional vinegars in the Philippines, it is threatened by the increasing use of industrially-produced vinegars. |
Paterson's worms | Paterson's worms are a family of cellular automata devised in 1971 by Mike Paterson and John Horton Conway to model the behaviour and feeding patterns of certain prehistoric worms. In the model, a worm moves between points on a triangular grid along line segments, representing food. Its turnings are determined by the configuration of eaten and uneaten line segments adjacent to the point at which the worm currently is. Despite being governed by simple rules the behaviour of the worms can be extremely complex, and the ultimate fate of one variant is still unknown. |
Prison rape | Prison rape or jail rape is sexual assault of people while they are incarcerated. The phrase is commonly used to describe rape of inmates by other inmates, or to describe rape of inmates by staff. |

Adjective | An adjective (abbreviated adj.) is a word that describes a noun or noun phrase. Its semantic role is to change information given by the noun.
Traditionally, adjectives were considered one of the main parts of speech of the English language, although historically they were classed together with nouns. Nowadays, certain words that usually had been classified as adjectives, including the, this, my, etc., typically are classed separately, as determiners.
Here are some examples: That's a funny idea. (attributive) That idea is funny. (predicative) Tell me something funny. (postpositive) The good, the bad, and the funny. (substantive) |
Neutral theory of molecular evolution | The neutral theory of molecular evolution holds that most evolutionary changes occur at the molecular level, and most of the variation within and between species are due to random genetic drift of mutant alleles that are selectively neutral. The theory applies only for evolution at the molecular level, and is compatible with phenotypic evolution being shaped by natural selection as postulated by Charles Darwin. The neutral theory allows for the possibility that most mutations are deleterious, but holds that because these are rapidly removed by natural selection, they do not make significant contributions to variation within and between species at the molecular level. A neutral mutation is one that does not affect an organism's ability to survive and reproduce. The neutral theory assumes that most mutations that are not deleterious are neutral rather than beneficial. Because only a fraction of gametes are sampled in each generation of a species, the neutral theory suggests that a mutant allele can arise within a population and reach fixation by chance, rather than by selective advantage.The theory was introduced by the Japanese biologist Motoo Kimura in 1968, and independently by two American biologists Jack Lester King and Thomas Hughes Jukes in 1969, and described in detail by Kimura in his 1983 monograph The Neutral Theory of Molecular Evolution. The proposal of the neutral theory was followed by an extensive "neutralist–selectionist" controversy over the interpretation of patterns of molecular divergence and gene polymorphism, peaking in the 1970s and 1980s. |

Phosphinous acids | Phosphinous acids are usually organophosphorus compounds with the formula R2POH. They are pyramidal in structure. Phosphorus is in the oxidation state III. Most phosphinous acids rapidly convert to the corresponding phosphine oxide, which are tetrahedral and are assigned oxidation state V. |
Alirocumab | Alirocumab, sold under the brand name Praluent, is a medication used as a second-line treatment for high cholesterol for adults whose cholesterol is not controlled by diet and statin treatment. It is a human monoclonal antibody that belongs to a novel class of anti-cholesterol drugs, known as PCSK9 inhibitors, and it was the first such agent to receive FDA approval. The FDA approval was contingent on the completion of further clinical trials to better determine efficacy and safety.Common side effects include nasopharyngitis (cold), injection site reactions, and influenza.It was approved for medical use in the United States and in the European Union in 2015. |
Laplace principle (large deviations theory) | In mathematics, Laplace's principle is a basic theorem in large deviations theory which is similar to Varadhan's lemma. It gives an asymptotic expression for the Lebesgue integral of exp(−θφ(x)) over a fixed set A as θ becomes large. Such expressions can be used, for example, in statistical mechanics to determining the limiting behaviour of a system as the temperature tends to absolute zero. |
Ethotoin | Ethotoin (previously marketed as Peganone) is an anticonvulsant drug used in the treatment of epilepsy. It is a hydantoin, similar to phenytoin. It is not available in the United States. |
Stratificational linguistics | Stratificational Linguistics, also known as Neurocognitive Linguistics (NCL) or Relational Network Theory (RNT), is an approach to linguistics advocated by Sydney Lamb that suggests language usage and production to be stratificational in nature. It regards the linguistic system of individual speakers as consisting of networks of relations which interconnect across different 'strata' or levels of language. These relational networks are hypothesized to correspond to maps of cortical columns in the human brain. Consequently, Stratificational Linguistics is related to the wider family of cognitive linguistic theories. Furthermore, as a functionalist approach to linguistics, Stratificational Linguistics shares a close relationship with Systemic Functional Linguistics (SFL). |
Ayds | Ayds Reducing Plan Candy (pronounced as "aids") is a discontinued appetite-suppressant candy that enjoyed strong sales in the 1970s and early 1980s and was originally manufactured by The Carlay Company. |

Optical sine theorem | In optics, the optical sine theorem states that the products of the index, height, and sine of the slope angle of a ray in object space and its corresponding ray in image space are equal. That is: n0y0a0=niyiai |
Glassy cell carcinoma of the cervix | Glassy cell carcinoma of the cervix, also glassy cell carcinoma, is a rare aggressive malignant tumour of the uterine cervix. The tumour gets its name from its microscopic appearance; its cytoplasm has a glass-like appearance. |
U11 spliceosomal RNA | The U11 snRNA (small nuclear ribonucleic acid) is an important non-coding RNA in the minor spliceosome protein complex, which activates the alternative splicing mechanism. The minor spliceosome is associated with similar protein components as the major spliceosome. It uses U11 snRNA to recognize the 5' splice site (functionally equivalent to U1 snRNA) while U12 snRNA binds to the branchpoint to recognize the 3' splice site (functionally equivalent to U2 snRNA). |
Winemaking in Bordeaux | Winemaking in Bordeaux is the collection of processes used to make Bordeaux wine. Winemaking in Bordeaux differs from winemaking in other places both because of the Bordelais climate and because of the particular Bordeaux style which the wine-maker is aiming for. A large number of processes are involved: pruning, training, spraying, (green harvesting), harvesting, (sorting), (de-stemming), crushing, fermentation, pressing, barrel-ageing, blending, bottling and bottle-ageing. |
Field Deployable Hydrolysis System | The Field Deployable Hydrolysis System (FDHS) is a transportable, high throughput neutralization system developed by the U.S. Army for converting chemical warfare material into compounds not usable as weapons. |

Silicide carbide | Silicide carbides or carbide silicides are compounds containing anions composed of silicide (Si4−) and carbide (C4−) or clusters therof. They can be considered as mixed anion compounds or intermetallic compounds, as silicon could be considered as a semimetal. Related compounds include the germanide carbides, phosphide silicides, boride carbides and nitride carbides. Other related compounds may contain more condensed anion combinations such as the carbidonitridosilicates with C(SiN3)4 with N bridging between two silicon atoms. |
International Journal of Computational Intelligence and Applications | The International Journal of Computational Intelligence and Applications is a refereed scientific journal published by Imperial College Press since 2001. It covers the theory and applications of computational intelligence and aims to provide "a vehicle whereby ideas using two or more conventional and computational intelligence based techniques could be discussed", such as neuro-fuzzy or evolutionary-symbolic combinations. |
Distorted Schwarzschild metric | In physics, the distorted Schwarzschild metric is the metric of a standard/isolated Schwarzschild spacetime exposed in external fields. In numerical simulation, the Schwarzschild metric can be distorted by almost arbitrary kinds of external energy–momentum distribution. However, in exact analysis, the mature method to distort the standard Schwarzschild metric is restricted to the framework of Weyl metrics. |
Sibernetic | Sibernetic is a fluid mechanics simulator developed for simulations of C. elegans in the OpenWorm project developed for the OpenWorm project by Andrey Palyanov, Sergey Khayrulin and Mike Vella as part of the OpenWorm team. Sibernetic provides an implementation of the PCISPH contractile matter algorithm for simulating muscle tissue and is applied to C. elegans locomotion. |
Emergent virus | An emergent virus (or emerging virus) is a virus that is either newly appeared, notably increasing in incidence/geographic range or has the potential to increase in the near future. Emergent viruses are a leading cause of emerging infectious diseases and raise public health challenges globally, given their potential to cause outbreaks of disease which can lead to epidemics and pandemics. As well as causing disease, emergent viruses can also have severe economic implications. Recent examples include the SARS-related coronaviruses, which have caused the 2002-2004 outbreak of SARS (SARS-CoV-1) and the 2019–21 pandemic of COVID-19 (SARS-CoV-2). Other examples include the human immunodeficiency virus which causes HIV/AIDS; the viruses responsible for Ebola; the H5N1 influenza virus responsible for avian flu; and H1N1/09, which caused the 2009 swine flu pandemic (an earlier emergent strain of H1N1 caused the 1918 Spanish flu pandemic). Viral emergence in humans is often a consequence of zoonosis, which involves a cross-species jump of a viral disease into humans from other animals. As zoonotic viruses exist in animal reservoirs, they are much more difficult to eradicate and can therefore establish persistent infections in human populations.Emergent viruses should not be confused with re-emerging viruses or newly detected viruses. A re-emerging virus is generally considered to be a previously appeared virus that is experiencing a resurgence, for example measles. A newly detected virus is a previously unrecognized virus that had been circulating in the species as endemic or epidemic infections. Newly detected viruses may have escaped classification because they left no distinctive clues, and/or could not be isolated or propagated in cell culture. Examples include human rhinovirus (a leading cause of common colds which was first identified in 1956), hepatitis C (eventually identified in 1989), and human metapneumovirus (first described in 2001, but thought to have been circulating since the 19th century). As the detection of such viruses is technology driven, the number reported is likely to expand. |
Kinin | A kinin is any of various structurally related polypeptides, such as bradykinin and kallidin. They are members of the autacoid family. Kinins are peptides that are cleaved from kininogens by the process of kallikreins. Kallikreins activate kinins when stimulated.It is a component of the kinin-kallikrein system.
Their precursors are kininogens. Kininogens contain a 9-11 amino acid bradykinin sequence.In botany, the plant hormones known as cytokinins were first called kinins, but the name was changed to avoid confusion. |
Final state conjecture | The final state conjecture is that the end state of the universe will consist of black holes and gravitational radiation. |
Saturation mutagenesis | Site saturation mutagenesis (SSM), or simply site saturation, is a random mutagenesis technique used in protein engineering, in which a single codon or set of codons is substituted with all possible amino acids at the position. There are many variants of the site saturation technique, from paired site saturation (saturating two positions in every mutant in the library) to scanning site saturation (performing a site saturation at every site in the protein, resulting in a library of size [20 x (number of residues in the protein)] that contains every possible point mutant of the protein). |
Biopharmaceutics Classification System | The Biopharmaceutics Classification System is a system to differentiate drugs on the basis of their solubility and permeability.This system restricts the prediction using the parameters solubility and intestinal permeability. The solubility classification is based on a United States Pharmacopoeia (USP) aperture. The intestinal permeability classification is based on a comparison to the intravenous injection. All those factors are highly important because 85% of the most sold drugs in the United States and Europe are orally administered. |
Science and technology in Pakistan | Science and technology is a growing field in Pakistan and has played an important role in the country's development since its founding. Pakistan has a large pool of scientists, engineers, doctors, and technicians assuming an active role in science and technology. The real growth in science in Pakistan occurred after the establishment of the Higher education Commission in 2002 which supported science in a big way and also became the major sponsor of the Pakistan Academy of Sciences under the leadership of Prof. Atta-ur-Rahman. The emphasis was placed on quality rather than numbers during this period. The quality measures introduced by Prof. Atta-ur-Rahman as Founding Chairman HEC included:1) All Ph.D. thesis were evaluated by eminent foreign scientists,2) All PhD theses and research papers were checked for plagiarism 3) Some 11,000 students were sent abroad to leading universities for PhD level training and absorbed on their return, 4) Appointments at faculty positions were linked to international stature of the applicants as judged from their international publications, patents and citations, and (5) Quality Enhancement Cells were established in all universities for the first time in the history of the country. (6) The minimum criteria for establishment of a new university were approved by the Cabinet and universities that did not meet this criteria were closed down. (7) The Model University Ordinance was approved (Appendix 3 in the reference) setting the governance parameters for new universities. (8) A list of fake higher education institutions was prepared and made public. (9) Quality Assurance Agency (QAA) was set up within the Higher Education Commission that established Quality Enhancement Cells (QECs) as its operational units in public and private-sector universities across the country. (10) The funding of universities was linked to excellence in teaching and research under a formula based funding mechanism that considered enrolment, subjects and quality of teaching and research. The first IT policy and implementation strategy was approved under the leadership of Prof. Atta-ur-Rahman, then Federal Minister of Science & technology, in August 2000 which laid the foundations of the development of this sector On the request of Prof. Atta-ur-Rahman, Intel initiated a nationwide programme to train school teachers in Information and Communication technologies in March 2002 which has led to the training of 220,000 school teachers in 70 districts and cities across Pakistan. A 15-year tax holiday was approved on the recommendation of Prof. Atta-ur-Rahman which has resulted in growth of IT business from $30 million in 2001 to over $3 billion. The Pakistan Austria University of Applied Engineering (Fachhochschule) has been established in Haripur Hazara under a Steering Committee Chaired by Prof. Atta-ur-Rahman in which students will get degrees from several Austrian universities. Pakistan's growth in scientific output can be seen from the fact that in 1990 Pakistan published 926 scholarly documents while in 2018 the number rose to 20548, a twenty times increase.In contrast India published 21443 scholarly documents in 1990 and the number rose to 171356 in 2018, an eight times increase. In 2018, 336 people per million were researchers in the R&D (Research and Development sector) in Pakistan compared to 256 people per million being researchers in India. The reforms begun by Prof. Atta-ur-Rahman FRS in 2003-2008 have continued over the subsequent decade and according to the Web of Science report, there was a 300% growth in research publications in 2019 over the decade, with 2019 marking the first year in which Pakistan was ranked above the world average in research. In 2019, Pakistan produced 300% more publications indexed in the Web of Science Core Collection than in 2010. In the decade of 2010-2019, more than half of Pakistan’s research was published in journals with Impact Factor. The global influence of Pakistan’s research is increasing as scientists in the country are publishing more in top quartile journals. The Category Normalized Citation Impact of Pakistan’s publications (which measures publications’ impact against their peers worldwide) has risen from 0.67 to 1.03. output. As of 2020, Pakistan has 85% teledensity with 183 million celllular, 98 million 3G/4G and 101 million broadband subscribers, due to the foundations laid by Prof. Atta-ur-Rahman of the IT and telecom industry during 2000-2008. In an analysis of scientific research productivity of Pakistan, in comparison to Brazil, Russia, India and China, Thomson Reuters has applauded the developments that have taken place as a result of the reforms introduced by Prof. Atta-ur-Rahman FRS, since Pakistan has emerged as the country with the highest increase in the percentage of highly cited papers in comparison to the "BRIC" countriesChemistry remains the strongest subject in the country with the International Center for Chemical and Biological Sciences playing the lead role with the largest postgraduate research program in the country having about 600 students enrolled for PhD. Physics (theoretical, nuclear, particle, laser, and quantum physics), material science, metallurgy (engineering), biology, and mathematics, are some of the other fields in which Pakistani scientists have contributed. From the 1960s and onwards, the Pakistani government made the development and advancement of science a national priority and showered top scientists with honours. While the government has made efforts to make science a part of national development, there have been criticisms of federal policies, such as the government's dissolution of the Higher Education Commission of Pakistan (HEC)— an administrative body that supervised research in science – in 2011. This attempted dissolution failed to materialise because of a Supreme Court of Pakistan decision on a petition filed by Prof. Atta-ur-Rahman, former Federal Minister of Science & Technology and former founding Chairman of the Higher Education Commission. Pakistani scientists have also won acclaim in mathematics and in several branches of physical science, notably theoretical and nuclear physics, chemistry, and astronomy. Professor Abdus Salam, a theoretical physicist won the Nobel Prize in Physics in 1979, being the first and only Pakistani to date to have received the honor. Prof. Atta-ur-Rahman an organic chemist was elected as Fellow of Royal Society (London) in 2006 in recognition of his contributions in the field of natural products thereby becoming the first scientist from the Islamic world to receive this honour for work carried out within an Islamic country. The contributions of Prof. Atta-ur-Rahman to uplift science and higher education in Pakistan were internationally acknowledged and a tribute paid to him in the world's leading science journal Nature that termed him as "a force of nature". In an analysis of scientific research productivity of Pakistan, in comparison to Brazil, Russia, India, and China, Thomson Reuters has applauded the developments that have taken place as a result of the reforms introduced by Prof. Atta-ur-Rahman FRS, since Pakistan has emerged as the country with the highest increase in the percentage of highly cited papers in comparison to the "BRIC" countries. In recognition of building strong bridges between science in Pakistan and China, Prof. Atta-ur-Rahman FRS received the highest national award of China, the "International Science and Technology Cooperation Award". His book on NMR spectroscopy published by Springer Verlag was translated into Japanese language and used for teaching courses on NMR spectroscopy in Japan. His book entitled "Stereoselective Synthesis in Organic Chemistry" published by Springer Verlag was described as a "monumental tome" by the Nobel Laureate Sir Derek Barton who wrote the Foreword to this book.Technology is highly developed in nuclear physics and explosives engineering, where the arms race with India convinced policymakers to set aside sufficient resources for research. Due to a programme directed by Munir Ahmad Khan and the Pakistan Atomic Energy Commission (PAEC), Pakistan is the seventh nation to have developed an atomic bomb, which the global intelligence community believes it had done by 1983 (see Kirana-I), nine years after India (see Pokhran-I). Pakistan first publicly tested its devices (see Chagai-I and Chagai-II) on 28 and 30 May 1998, two weeks after India carried out its own tests (See Pokhran-II).Space exploration was hastily developed, in 1990 Pakistan launched Badr-1 followed by Badr-II in 2001. Since the 1980s, the space programme dedicated itself to military technologies (Space weapons programme and Integrated missile systems), and maintains a strong programme developed for military applications. |

Ikitoxin | Ikitoxin is a neurotoxin from the venom of the South African Spitting scorpion (Parabuthus transvaalicus) that targets voltage-sensitive sodium channels. It causes unprovoked jumps in mice following intracerebroventricular injections. |
Zinc finger and scan domain containing 30 | Zinc finger and SCAN domain containing 30 is a protein that in humans is encoded by the ZSCAN30 gene. |
GJA1 | Gap junction alpha-1 protein (GJA1), also known as connexin 43 (Cx43), is a protein that in humans is encoded by the GJA1 gene on chromosome 6. As a connexin, GJA1 is a component of gap junctions, which allow for gap junction intercellular communication (GJIC) between cells to regulate cell death, proliferation, and differentiation. As a result of its function, GJA1 is implicated in many biological processes, including muscle contraction, embryonic development, inflammation, and spermatogenesis, as well as diseases, including oculodentodigital dysplasia (ODDD), heart malformations, and cancers. |
Propellant mass fraction | In aerospace engineering, the propellant mass fraction is the portion of a vehicle's mass which does not reach the destination, usually used as a measure of the vehicle's performance. In other words, the propellant mass fraction is the ratio between the propellant mass and the initial mass of the vehicle. In a spacecraft, the destination is usually an orbit, while for aircraft it is their landing location. A higher mass fraction represents less weight in a design. Another related measure is the payload fraction, which is the fraction of initial weight that is payload. It can be applied to a vehicle, a stage of a vehicle or to a rocket propulsion system. |
Multi-antimicrobial extrusion protein | Multi-antimicrobial extrusion protein (MATE) also known as multidrug and toxin extrusion or multidrug and toxic compound extrusion is a family of proteins which function as drug/sodium or proton antiporters. |
Tragic triad | The tragic triad is a term used in logotherapy, coined by Dr. Viktor Frankl. The tragic triad refers to three experiences which often lead to existential crisis, namely, guilt, suffering or death. The concept of the tragic triad is used in identifying the life meanings of patients, or the relatives of patients, experiencing guilt, suffering or death. These life meanings are analyzed using logotherapy's existential analysis with the intent of assisting the patient overcome their existential crisis by discovering meaning or purpose in the experience.Frankl argued that all human beings at one point in their lives will encounter the tragic triad. |
HSPA7 | Heat shock 70kDa protein 7 (HSP70B) also known as HSPA7 is a human gene. The protein encoded by this gene is a member of the Hsp70 family of heat shock proteins. |
3,4-Methylenedioxyphentermine | 3,4-Methylenedioxyphentermine (MDPH) is a lesser-known psychedelic drug. MDPH was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 160–240 mg, and the duration as 3–5 hours. MDPH's effects are very similar to those of MDA: they both are smooth and "stoning," and do not cause any visuals. They also alter dreams and dream patterns. Shulgin describes MDPH as a promoter; it promotes the effects of other drugs, similarly to 2C-D. Very little data exists about the pharmacological properties, metabolism, and toxicity of MDPH. |
Rocket engine | A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. |
Malvin | Malvin is a naturally occurring chemical of the anthocyanin family.
Malvin reacts in the presence of H2O2 to form malvone. The ortho-benzoyloxyphenylacetic acid esters reaction product is dependant of the pH: it is obtained under acidic conditions whereas under neutral conditions, the reaction product is the 3-O-acyl-glucosyl-5-O-glucosyl-7-hydroxy coumarin. |
SYT7 | Synaptotagmin-7 is a protein that in humans is encoded by the SYT7 gene. |
NDUFA12 | NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 12 is an enzyme that in humans is encoded by the NDUFA12 gene. The NDUFA12 protein is a subunit of NADH dehydrogenase (ubiquinone), which is located in the mitochondrial inner membrane and is the largest of the five complexes of the electron transport chain. Mutations in subunits of NADH dehydrogenase (ubiquinone), also known as Complex I, frequently lead to complex neurodegenerative diseases such as Leigh's syndrome that result from mitochondrial complex I deficiency. |
Silicon controlled rectifier | A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device. The name "silicon controlled rectifier" is General Electric's trade name for a type of thyristor. The principle of four-layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey, and Holonyak of Bell Laboratories in 1956. The practical demonstration of silicon controlled switching and detailed theoretical behavior of a device in agreement with the experimental results was presented by Dr Ian M. Mackintosh of Bell Laboratories in January 1958. The SCR was developed by a team of power engineers led by Gordon Hall and commercialized by Frank W. "Bill" Gutzwiller in 1957. |
Endodontics | Endodontics (from the Greek roots endo- "inside" and odont- "tooth") is the dental specialty concerned with the study and treatment of the dental pulp. |
Solar energy in Finland | Solar energy in Finland is used primarily for water heating and by the use of photovoltaics to generate electricity. As a northern country, summer days are long and winter days are short. Above the Arctic Circle, the sun does not rise some days in winter, and does not set some days in the summer. Due to the low sun angle, it is more common to place solar panels on the south side of buildings instead of on the roof. Mounting them vertically reduces the average output by 22% from mounting at a 60° angle. |
Krauss-Helmholtz bogie | A Krauss-Helmholtz bogie (Krauss-Helmholtz-Lenkgestell) is a mechanism used on steam locomotives and some electric locomotives to improve curve running. |
Multi-spectral phase coherence | Multi-spectral phase coherence (MSPC) is a generalized cross-frequency coupling metric introduced by Yang and colleagues in 2016. MSPC can be used to quantify nonlinear phase coupling between a set of base frequencies and their harmonic/intermodulation frequencies. MSPC is a model-free method, which can provide a system description, including (i) the order of the nonlinearity, (ii) the direction of interaction, (iii) the time delay in the system, and both (iv) harmonic and (v) intermodulation coupling. |
TRNA (cytosine-5-)-methyltransferase | In enzymology, a tRNA (cytosine-5-)-methyltransferase (EC 2.1.1.29) is an enzyme that catalyzes the chemical reaction S-adenosyl-L-methionine + tRNA ⇌ S-adenosyl-L-homocysteine + tRNA containing 5-methylcytosineThus, the two substrates of this enzyme are S-adenosyl methionine and tRNA, whereas its two products are S-adenosylhomocysteine and tRNA containing 5-methylcytosine.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:tRNA (cytosine-5-)-methyltransferase. Other names in common use include transfer ribonucleate cytosine 5-methyltransferase, and transfer RNA cytosine 5-methyltransferase. |
Serrated blade | A serrated blade is one with a toothlike rather than a plain edge, and is used on saws and on some knives and scissors. It is also known as a dentated, sawtooth, or toothed blade. Most such blades are scalloped, having edges cut with curved notches, common on wood saws and bread knives. Serrations give the blade's cutting edge less contact area than a smooth blade, which increases the applied pressure at each point of contact, and the points of contact are at a sharper angle to the material being cut. This causes a cutting action that involves many small splits in the surface of the material being cut, which cumulatively serve to cut the material along the line of the blade.Cuts made with a serrated blade are typically less smooth and precise than cuts made with a smooth blade. Serrated edges can be difficult to sharpen using a whetstone or rotary sharpener intended for straight edges but can be sharpened with ceramic or diamond coated rods. Further, they tend to stay sharper longer than similar straight edges. A serrated blade has a faster cut, but a plain edge has a cleaner cut. Some prefer a serrated blade on a pocket knife. |
Isopropylphenidate | Isopropylphenidate (also known as IPH and IPPD) is a piperidine based stimulant drug, closely related to methylphenidate, but with the methyl ester replaced by an isopropyl ester. It has similar effects to methylphenidate but with a longer duration of action, and was banned in the UK as a Temporary Class Drug from April 2015 following its unapproved sale as a designer drug.It has been researched as potential methylphenidate replacement for ADHD and narcolepsy, because of fewer side effects. |
Indium trihydride | Indium trihydride is an inorganic compound with the chemical formula (InH3). It has been observed in matrix isolation and laser ablation experiments. Gas phase stability has been predicted. The infrared spectrum was obtained in the gas phase by laser ablation of indium in presence of hydrogen gas InH3 is of no practical importance. |
Anti-nesting principle | In the philosophy of consciousness, the anti-nesting principle states that one state of consciousness cannot exist within another.Proponents of the anti-nesting principle include Giulio Tononi and Hilary Putnam. |
Simultaneously extracted metals and acid-volatile sulfide | Simultaneously extracted metals/Acid-volatile sulfide (SEM-AVS) is an approach used in the field of aquatic toxicology to assess the potential for metal ions found in sediment to cause toxic effects in organisms dwelling in the sediment. In this approach, the amounts of several heavy metals in a sediment sample are measured in a laboratory; at the same time, the amount of acid-volatile sulfide (sulfide which can be liberated from the sediment by treatment with hydrochloric acid) is determined. Based on the chemical interactions between heavy metals (SEM) and acid-volatile sulfide (AVS), the concentrations of these two components can be used to assess the potential for toxicity to sediment-dwelling organisms. |
Medium of instruction | A medium of instruction (plural: media of instruction, or mediums of instruction) is a language used in teaching. It may or may not be the official language of the country or territory. If the first language of students is different from the official language, it may be used as the medium of instruction for part or all of schooling. Bilingual education or multilingual education may involve the use of more than one language of instruction. UNESCO considers that "providing education in a child's mother tongue is indeed a critical issue". In post-secondary, university and special education settings, content may often be taught in a language that is not spoken in the students' homes. This is referred to as content based learning or content and language integrated learning (CLIL). In situations where the medium of instruction of academic disciplines is English when it is not the students' first language, the phenomenon is referred to as English-medium instruction (EMI). |
2-hydroxyphytanoyl-CoA lyase | 2-Hydroxyphytanoyl-CoA lyase is a peroxisomal enzyme involved in the catabolism of phytanoic acid by α-oxidation. It requires thiamine diphosphate (ThDP) as cofactor.It is classified under EC number 4.1. |
Inverted cone filtration | Inverted cone filtration (ICF) is a process used to remove particulate and dissolved contaminants from a designated fluid such as water. In a typical design, fluid enters the narrow top end of the filter falling onto a chamber where pressure head is built to force the fluid across woven filter media. The pressure differential on the inner and outer wall of the filter is caused by a low pressure outlet pipe that carries out the treated fluid. |
Methylene green | Methylene green is a heterocyclic aromatic chemical compound similar to methylene blue. It is used as a dye. It functions as a visible light-activated photocatalyst in organic synthesis. |
Lateritic nickel ore deposits | Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks.
They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel. |
I3C (bus) | I3C is a specification to enable communication between computer chips by defining the electrical connection between the chips and signaling patterns to be used. Short for "Improved Inter Integrated Circuit", the standard defines the electrical connection between the chips to be a two wire, shared (multidrop), serial data bus, one wire (SCL) being used as a clock to define the sampling times, the other wire (SDA) being used as a data line whose voltage can be sampled. The standard defines a signalling protocol in which multiple chips can control communication and thereby act as the bus controller. |
Insert (print advertising) | In advertising, an insert or blow-in card is a separate advertisement put in a magazine, newspaper, or other publication. They are usually the main source of income for non-subscription local newspapers and other publications. Sundays typically bring numerous large inserts in newspapers, because most weekly sales begin on that day, and it also has the highest circulation of any day of the week.A buckslip or buck slip is a slip of paper, often the size of a U.S. dollar bill (a buck), which includes additional information about a product.Bind-in cards are cards that are bound into the bindings of the publication, and will therefore not drop out. |
Viral pathogenesis | Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level. It is a specialized field of study in virology.Pathogenesis is a qualitative description of the process by which an initial infection causes disease. Viral disease is the sum of the effects of viral replication on the host and the host's subsequent immune response against the virus. Viruses are able to initiate infection, disperse throughout the body, and replicate due to specific virulence factors.There are several factors that affect pathogenesis. Some of these factors include virulence characteristics of the virus that is infecting. In order to cause disease, the virus must also overcome several inhibitory effects present in the host. Some of the inhibitory effects include distance, physical barriers and host defenses. These inhibitory effects may differ among individuals due to the inhibitory effects being genetically controlled. |
Karn's algorithm | Karn's algorithm addresses the problem of getting accurate estimates of the round-trip time for messages when using the Transmission Control Protocol (TCP) in computer networking. The algorithm, also sometimes termed as the Karn-Partridge algorithm was proposed in a paper by Phil Karn and Craig Partridge in 1987.Accurate round trip estimates in TCP can be difficult to calculate because of an ambiguity created by retransmitted segments. The round trip time is estimated as the difference between the time that a segment was sent and the time that its acknowledgment was returned to the sender, but when packets are re-transmitted there is an ambiguity: the acknowledgment may be a response to the first transmission of the segment or to a subsequent re-transmission. |
Problem frames approach | Problem analysis or the problem frames approach is an approach to software requirements analysis. It was developed by British software consultant Michael A. Jackson in the 1990s. |
Chromosomal deletion syndrome | Chromosomal deletion syndromes result from deletion of parts of chromosomes. Depending on the location, size, and whom the deletion is inherited from, there are a few known different variations of chromosome deletions. Chromosomal deletion syndromes typically involve larger deletions that are visible using karyotyping techniques. Smaller deletions result in Microdeletion syndrome, which are detected using fluorescence in situ hybridization (FISH) Examples of chromosomal deletion syndromes include 5p-Deletion (cri du chat syndrome), 4p-Deletion (Wolf–Hirschhorn syndrome), Prader–Willi syndrome, and Angelman syndrome. |
Lingerie | Lingerie (UK: , US: , French: [lɛ̃ʒʁi] (listen)) is a category of primarily women's clothing including undergarments (mainly brassieres), sleepwear, and lightweight robes. The choice of the word is often motivated by an intention to imply that the garments are alluring, fashionable, or both. In a 2015 US survey, 75% of women and 26% of men reported having worn "sexy lingerie" in their lifetime.Lingerie is made of lightweight, stretchy, smooth, sheer or decorative fabrics such as silk, satin, Lycra, charmeuse, chiffon, or (especially and traditionally) lace. These fabrics can be made of various natural fibres like silk or cotton or of various synthetic fibres like polyester or nylon. |
Occupational asthma | Occupational asthma is new onset asthma or the recurrence of previously quiescent asthma directly caused by exposure to an agent at workplace. It is an occupational lung disease and a type of work-related asthma. Agents that can induce occupational asthma can be grouped into sensitizers and irritants.Sensitizer-induced occupational asthma is an immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.Irritant-induced (occupational) asthma is a non-immunologic form of asthma that results from a single or multiple high dose exposure to irritant products. It is usually develops early after exposure; however can also develop insidiously over a few months after a massive exposure to a complex mixture of alkaline dust and combustion products, as shown in the World Trade Center disaster. Unlike those with sensitizer-induced occupational asthma, subjects with irritant-induced occupational asthma do not develop work-related asthma symptoms after re-exposure to low concentrations of the irritant that initiated the symptoms. Reactive airways dysfunction syndrome (RADS) is a severe form of irritant induced asthma where respiratory symptoms usually develop in the minutes or hours after a single accidental inhalation of a high concentration of irritant gas, aerosol, vapor, or smoke.Another type of work-related asthma is work-exacerbated asthma (WEA) which is asthma worsened by workplace conditions but not caused by it. WEA is present in about a fifth of patients with asthma and a wide variety of conditions at work, including irritant chemicals, dusts, second-hand smoke, common allergens that may be present at work, as well as other "exposures" such as emotional stress, worksite temperature, and physical exertion can exacerbate asthma symptoms in these patients. Both occupational asthma and work-exacerbated asthma can be present in an individual. |
Pork blood soup | Pork blood soup is a soup that uses pork blood as its primary ingredient. Additional ingredients may include barley and herbs such as marjoram, as well as other foods and seasonings. Some versions are prepared with coagulated pork blood and other coagulated pork offal, such as intestine, liver and heart. |
Autocoding | Autocoding refers to software solutions that help manufacturers, particularly those in the food industry, ensure that products have the correct packaging and correct 'sell by' date codes, thereby reducing the number of Emergency Product Withdrawals (EPW). The term was first used during an initiative between Geest PLC (acquired by Bakkavör in 2005 ) and Tesco in 2001. The key objective of the software was to reduce the number of EPW's associated with date and price coding errors, and pot and lid marriage errors. This still remains the main objective of autocoding software, but functionality has been expanded to encompass quality assurance and OEE performance data. |
Functional (mathematics) | In mathematics, a functional (as a noun) is a certain type of function. The exact definition of the term varies depending on the subfield (and sometimes even the author). |
Milkshape 3D | MilkShape 3D (MS3D) is a shareware low-polygon 3D modeling program created by Mete Ciragan. It is used mainly for compiling models for Half-Life, Blockland, The Sims 2, The Sims 3, Rock Raiders, and other sandbox video games. It is also used to create models for a large number of indie games, Milkshape 3D's repertoire of export capabilities has been extended considerably, due to the efforts of both its creator and the community around it, and it is now able to be used for most games today, so long as an exporter for the required format is available. |
Metocean | In offshore and coastal engineering, metocean refers to the syllabic abbreviation of meteorology and (physical) oceanography. |
Ping Zhang (biologist) | Ping Zhang is an American structural biologist researching the structural and mechanistic basis of multi-component kinase signaling complexes that are linked to human cancers and other diseases, with a long-term goal of developing new therapeutic strategies. She is a NIH Stadtman Investigator in the Structural Biophysics Laboratory at the National Cancer Institute. |
Are We There Yet? (video game) | Are We There Yet? is a 1991 puzzle video game developed by Manley & Associates for IBM PC compatibles and published by Electronic Arts. |
Non sequitur (literary device) | A non sequitur (English: non SEK-wit-ər, Classical Latin: [noːn ˈsɛkᶣɪtʊr]; "[it] does not follow") is a conversational literary device, often used for comedic purposes. It is something said that, because of its apparent lack of meaning relative to what preceded it, seems absurd to the point of being humorous or confusing. This use of the term is distinct from the non sequitur in logic, where it is a fallacy. |
Washout (aeronautics) | Washout is a characteristic of aircraft wing design which deliberately reduces the lift distribution across the span of an aircraft’s wing. The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip. This is usually to ensure that at stall speed the wing root stalls before the wing tips, providing the aircraft with continued aileron control and some resistance to spinning. Washout may also be used to modify the spanwise lift distribution to reduce lift-induced drag. |
Fröhlich effect | The Fröhlich effect is a visual illusion wherein the first position of a moving object entering a window is misperceived. When observers are asked to localize the onset position of the moving target, they typically make localization errors in the direction of movement ("ahead" of its true localization).A proposed explanation for this effect is that the visual system is predictive, accounting for neural delays by extrapolating the trajectory of a moving stimulus into the future. In other words, when light from a moving object hits the retina, a certain amount of time is required before the object is perceived. In that time, the object has moved to a new location in the world. The motion extrapolation hypothesis asserts that the visual system will take care of such delays by extrapolating the position of moving objects forward in time. As such it is related to the flash lag illusion. |
