HD 165590 | HD 165590 is a quintuple system dominated by the binary Algol variable star known as V772 Herculis. The system lies in the constellation of Hercules about 123 light years from the Sun, and is suspected to be a part of the Pleiades moving group. |
George-ericksenite | George-ericksenite is a mineral with the chemical formula Na6CaMg(IO3)6(CrO4)2(H2O)12. It is vitreous, pale yellow to bright lemon yellow, brittle, and features a prismatic to acicular crystal habit along [001] and somewhat flattened crystal habit on {110}. It was first encountered in 1984 at the Pinch Mineralogical Museum. One specimen of dietzeite from Oficina Chacabuco, Chile had bright lemon-yellow micronodules on it. These crystals produced an X-ray powder diffraction pattern that did not match any XRD data listed for inorganic compounds. The X-ray diffraction pattern and powder mount were set aside until 1994. By then, the entire mineral collection from the Pinch Mineralogical Museum had been purchased by the Canadian Museum of Nature. The specimen was then retrieved and studied further. This study was successful and the new mineral george-ericksenite was discovered. The mineral was named for George E. Ericksen who was a research economic geologist with the U.S. Geological Survey for fifty years. The mineral and name have been approved by Commission on New Minerals and Mineral Names (IMA). The specimen, polished thin section, and the actual crystal used for the structure determination are kept in the Display Series of the National Mineral Collection of Canada at the Canadian Museum of Nature, Ottawa, Ontario. |
Floorwalker | A floorwalker is a senior employee in a large store (usually a department store) who supervises sales staff, in addition to directing and assisting customers and resolving complaints and returns. Until the early 20th century, when formal training came into vogue, the floorwalker would often be responsible for training new sales staff. |
Random coordinate descent | Randomized (Block) Coordinate Descent Method is an optimization algorithm popularized by Nesterov (2010) and Richtárik and Takáč (2011). The first analysis of this method, when applied to the problem of minimizing a smooth convex function, was performed by Nesterov (2010). In Nesterov's analysis the method needs to be applied to a quadratic perturbation of the original function with an unknown scaling factor. Richtárik and Takáč (2011) give iteration complexity bounds which do not require this, i.e., the method is applied to the objective function directly. Furthermore, they generalize the setting to the problem of minimizing a composite function, i.e., sum of a smooth convex and a (possibly nonsmooth) convex block-separable function: F(x)=f(x)+Ψ(x), where Ψ(x)=∑i=1nΨi(x(i)), x∈RN is decomposed into n blocks of variables/coordinates: x=(x(1),…,x(n)) and Ψ1,…,Ψn are (simple) convex functions. |
General Catalogue of Variable Stars | The General Catalogue of Variable Stars (GCVS) is a list of variable stars in the Milky Way Galaxy. Its first edition, containing 10,820 stars, was published in 1948 by the Academy of Sciences of the USSR, edited by Boris Kukarkin and Pavel Parenago. Second and third editions were published in 1958 and 1968. The fourth edition, containing 28,435 stars, was published in three volumes in 1985–1987. Later, two more volumes were published: the fourth volume containing reference tables and the fifth volume containing extragalactic variable stars. The first release of the fifth edition (GCVS 5.1), which is periodically updated, currently contains 58,035 variable stars; it is available at the GCVS website and at the VizieR astronomical catalogue service. |
4-hydroxythreonine-4-phosphate dehydrogenase | In enzymology, a 4-hydroxythreonine-4-phosphate dehydrogenase (EC 1.1.1.262) is an enzyme that catalyzes the chemical reaction 4-phosphonooxy-L-threonine + NAD+ ⇌ (2S)-2-amino-3-oxo-4-phosphonooxybutanoate + NADH + H+Thus, the two substrates of this enzyme are 4-phosphonooxy-L-threonine and NAD+, whereas its 3 products are (2S)-2-amino-3-oxo-4-phosphonooxybutanoate, NADH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 4-phosphonooxy-L-threonine:NAD+ oxidoreductase. Other names in common use include NAD+-dependent threonine 4-phosphate dehydrogenase, L-threonine 4-phosphate dehydrogenase, 4-(phosphohydroxy)-L-threonine dehydrogenase, PdxA, and 4-(phosphonooxy)-L-threonine:NAD+ oxidoreductase. This enzyme participates in vitamin B6 metabolism. |
Sodium salicylate | Sodium salicylate is a sodium salt of salicylic acid. It can be prepared from sodium phenolate and carbon dioxide under higher temperature and pressure. Historically, it has been synthesized by refluxing methyl salicylate (wintergreen oil) with an excess of sodium hydroxide. |
Quantization (music) | In digital music processing technology, quantization is the studio-software process of transforming performed musical notes, which may have some imprecision due to expressive performance, to an underlying musical representation that eliminates the imprecision. The process results in notes being set on beats and on exact fractions of beats.The purpose of quantization in music processing is to provide a more beat-accurate timing of sounds. Quantization is frequently applied to a record of MIDI notes created by the use of a musical keyboard or drum machine. Additionally, the phrase "pitch quantization" can refer to pitch correction used in audio production, such as using Auto-Tune. |
House blessing | House blessings (also known as house healings, house clearings, house cleansings and space clearing) are rites intended to protect the inhabitants of a house or apartment from misfortune, whether before moving into it or to "heal" it after an occurrence. Many religions have house blessings of one form or another. |
LY-255582 | LY-255582 is a phenylpiperidine non-selective opioid antagonist. It has been shown to reduce ethanol consumption in experiments carried out on rats. It has also been shown to reduce food and water consumption in rats. |
Geislinger coupling | The Geislinger coupling is an all-metal coupling for rotating shafts. It is elastic in torsion, allowing it to absorb torsional vibration.Unlike some other coupling types, it is not intended to compensate for high radial mis-alignment between shafts, but it can compensate axial misalignments better than elastomer couplings. The coupling may have a small ability to compensate for varying alignment, but if this is needed it is generally done through using an additional coupling in tandem. The coupling also runs at the same speed for input and output shafts, unlike a torque converter. |
Amplitude modulation | Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal. This technique contrasts with angle modulation, in which either the frequency of the carrier wave is varied, as in frequency modulation, or its phase, as in phase modulation. |
Rock violin | Rock violin is rock music that includes violin in its instrumental lineup. This includes rock music only and does not include classical style music using melodic motifs from rock. |
Δ-Tocopherol | δ-Tocopherol (delta-tocopherol) is a tocopherol and one of the chemical compounds that is considered vitamin E. As a food additive, it has E number E309. |
Niwar (cotton tape) | Niwar (also known as newar, niwar, nivar, navār, or nuwār) is a coarse, narrow, thick tape that was initially made of cotton only. Niwar is a textile product produced on tape looms and classified as a narrow-width fabric. Baden Henry Powell referred to it as "broad coarse tape", a product of the jail industry. In his book Handbook of the Manufactures and Arts of the Punjab, Powell classified niwar under the category of "tape, string, and miscellaneous cotton products". A weaver of this tape is called a niwar-baf. |
Cryocooler | A refrigerator designed to reach cryogenic temperatures (below 120 K, −153 °C) is often called a cryocooler. The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some can have input powers as low as 2–3 W. Large systems, such as those used for cooling the superconducting magnets in particle accelerators are more often called cryogenic refrigerators. Their input powers can be as high as 1 MW. In most cases cryocoolers use a cryogenic fluid as the working substance and employ moving parts to cycle the fluid around a thermodynamic cycle. The fluid is typically compressed at room temperature, precooled in a heat exchanger, then expanded at some low temperature. The returning low-pressure fluid passes through the heat exchanger to precool the high-pressure fluid before entering the compressor intake. The cycle is then repeated. |
Galactosialidosis | Galactosialidosis, also known as neuraminidase deficiency with beta-galactosidase deficiency, is a genetic lysosomal storage disease. It is caused by a mutation in the CTSA gene which leads to a deficiency of enzymes β-galactosidase and neuraminidase. This deficiency inhibits the lysosomes of cells from functioning properly, resulting in the accumulation of toxic matter within the cell. Hallmark symptoms include abnormal spinal structure, vision problems, coarse facial features, hearing impairment, and intellectual disability. Because galactosialidosis involves the lysosomes of all cells, it can affect various areas of the body, including the brain, eyes, bones, and muscles. Depending on the patient's age at the onset of symptoms, the disease consists of three subtypes: early infantile, late infantile, and juvenile/adult. This condition is considered rare, with most cases having been in the juvenile/adult group of patients. |
Fish scale | A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term scale derives from the Old French escale, meaning a shell pod or husk.Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. |
Dyslexie | Dyslexie is a typeface/font that was designed with the intention of mitigating some of the issues that dyslexics experience when reading. As many of the twenty-six letters of the basic Latin alphabet are visually very similar, the typeface emphasizes the parts of the letter that are different from each other.There is no evidence that the font aids reading, neither in those with, nor without, dyslexia. |
Gastric distension | Gastric distention is the enlargement of the stomach, and can be due to a number of causes.Physiologic (normal) gastric distension occurs when eating. Distension of the upper stomach stimulates the secretion of stomach acid, while distension of the lower stomach stimulates gastrin secretion. Distension of the stomach also stimulates the secretion of ghrelin.Other causes include: binge eating associated with bulimia nervosa tumors causing obstruction diabetic neuropathy scarring due to pyloric gastritis delayed gastric emptyingTo identify the cause of gastric distention, an upper endoscopy or barium upper GI imaging should be done. |
Vendor | In a supply chain, a vendor, supplier, provider or a seller, is an enterprise that contributes goods or services. Generally, a supply chain vendor manufactures inventory/stock items and sells them to the next link in the chain. Today, these terms refer to a supplier of any goods or service. |
GLAM (cultural heritage) | GLAM is an acronym for galleries, libraries, archives, and museums, and refers to cultural institutions with a mission to provide access to knowledge. GLAMs collect and maintain cultural heritage materials in the public interest. As collecting institutions, GLAMs preserve and make accessible primary sources valuable for researchers.
Versions of the acronym include GLAMR, which specifies records management, and the earlier form LAM, which did not specify "galleries" (whether seen as a subset of museums, or else potentially confused with commercial establishments where art is bought and sold). Another form also is GLAMA, which specifies academia, or alternatively GLEAM ("Education"). |
Dry blender | Dry blenders are a type of industrial mixer which are typically used to blend multiple dry components until they are homogeneous. Often minor liquid additions are made to the dry blend to modify the product formulation. Blending times using dry ingredients are often short (15–30 minutes) but are somewhat dependent upon the varying percentages of each component, and the difference in the bulk densities of each. |
Polydactyly-myopia syndrome | Polydactyly-myopia syndrome, also known as Czeizel-Brooser syndrome, is a very rare genetic disorder which is characterized by post-axial polydactyly on all 4 limbs and progressive myopia. Additional symptoms include bilateral congenital inguinal hernia and undescended testes. It has only been described in nine members of a 4-generation Hungarian family in the year 1986. This disorder is inherited in an autosomal dominant manner. |

MicroRNAs function to regulate the expression levels of other genes by several mechanisms. mir-25 levels increase in human heart failure, and treatment with an anti-sense RNA molecule (antagomiR) was recently reported to halt disease progression and improves cardiac function in a mouse heart failure model. |
Hydroxyl tagging velocimetry | Hydroxyl tagging velocimetry (HTV) is a velocimetry method used in humid air flows. The method is often used in high-speed combusting flows because the high velocity and temperature accentuate its advantages over similar methods. HTV uses a laser (often an argon-fluoride excimer laser operating at ~193 nm) to dissociate the water in the flow into H + OH. Before entering the flow optics are used to create a grid of laser beams. The water in the flow is dissociated only where beams of sufficient energy pass through the flow, thus creating a grid in the flow where the concentrations of hydroxyl (OH) are higher than in the surrounding flow. Another laser beam (at either ~248 nm or ~308 nm) in the form of a sheet is also passed through the flow in the same plane as the grid. This laser beam is tuned to a wavelength that causes the hydroxyl molecules to fluoresce in the UV spectrum. The fluorescence is then captured by a charge-coupled device (CCD) camera. Using electronic timing methods the picture of the grid can be captured at nearly the same instant that the grid is created. By delaying the pulse of the fluorescence laser and the camera shot, an image of the grid that has now displaced downstream can be captured. Computer programs are then used to compare the two images and determine the displacement of the grid. By dividing the displacement by the known time delay the two dimensional velocity field (in the plane of the grid) can be determined. Flow ratios, however, are shown to affect the impingement locations, where increased air flow ratios can reduce the required combustor size by isolating reaction products solely within the secondary cavity. Other molecular tagging velocimetry (MTV) methods have used ozone (O3), excited oxygen and nitric oxide as the tag instead of hydroxyl. In the case of ozone the method is known as ozone tagging velocimetry or OTV. OTV has been developed and tested in many room air temperature applications with very accurate test results. OTV consists of an initial "write" step, where a 193-nm pulsed excimer laser creates ozone grid lines via oxygen (O2) UV absorption, and a subsequent "read" step, where a 248-nm excimer laser photodissociates the formed O3 and fluoresces the vibrationally excited O2 product thus revealing the grid lines' displacement. |
Weather Stress Index | The Weather Stress Index, or WSI, is a relative measure of the weather conditions, often used as a comfort indicator. The index, a number between 0 and 100, represents the percentage of time in the past with temperatures below the current temperature, for a given location, day and time. This makes the index a local measure based in past weather conditions. For example, if for a given location, on the 25th of July at 13:00 UTC the WSI is 85 for a temperature of 42 °C (108 °F), this means that the temperature was inferior to 42 °C in 85% of the time in the past, on the same place, on the 25th of July at 13:00 UTC (and superior to 42 °C in 15% of the time on the same place, day and hour). In other words, the WSI gives the probability of finding a smaller temperature in the local weather history, at a given day and time, than that of the present measurement. Therefore, high values of WSI predict a relative discomfort from excessive heat for local inhabitants. |
Digital print matrix | A digital print matrix is the digital state from which a print art object can be instanced with original intent. |
Hidden-line removal | In 3D computer graphics, solid objects are usually modeled by polyhedra. A face of a polyhedron is a planar polygon bounded by straight line segments, called edges. Curved surfaces are usually approximated by a polygon mesh. Computer programs for line drawings of opaque objects must be able to decide which edges or which parts of the edges are hidden by an object itself or by other objects, so that those edges can be clipped during rendering. This problem is known as hidden-line removal. |
Tonicization | In music, tonicization is the treatment of a pitch other than the overall tonic (the "home note" of a piece) as a temporary tonic in a composition. In Western music that is tonal, the piece is heard by the listener as being in a certain key. A tonic chord has a dominant chord; in the key of C major, the tonic chord is C major and the dominant chord is G major or G dominant seventh. The dominant chord, especially if it is a dominant seventh, is heard by Western composers and listeners familiar with music as resolving (or "leading") to the tonic, due to the use of the leading note in the dominant chord. A tonicized chord is a chord other than the tonic chord to which a dominant or dominant seventh chord progresses. When a dominant chord or dominant seventh chord is used before a chord other than the tonic, this dominant or dominant seventh chord is called a secondary dominant. When a chord is tonicized, this makes this non-tonic chord sound temporarily like a tonic chord. |
Rookie | A rookie is a person new to an occupation, profession, or hobby. In sports, a rookie is a professional athlete in their first season (or year).
In contrast with a veteran who has experience, a rookie is typically considered needing more training and learning, though they may bring a new outside expertise to a job. |
Douglas Lenat | Douglas Bruce Lenat (born 1950) is the CEO of Cycorp, Inc. of Austin, Texas, and has been a prominent researcher in artificial intelligence. Lenat was awarded the biannual IJCAI Computers and Thought Award in 1976 for creating the machine-learning program AM. He has worked on (symbolic, not statistical) machine learning (with his AM and Eurisko programs), knowledge representation, "cognitive economy", blackboard systems, and what he dubbed in 1984 "ontological engineering" (with his Cyc program at MCC and, since 1994, at Cycorp). He has also worked in military simulations, and numerous projects for US government, military, intelligence, and scientific organizations. In 1980, he published a critique of conventional random-mutation Darwinism. He authored a series of articles in the Journal of Artificial Intelligence exploring the nature of heuristic rules. |
Leather | Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators.Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India.Critics of tanneries claim that they engage in unsustainable practices that pose health hazards to the people and the environment near them. |

Energy gap | In solid-state physics, an energy gap or band gap is an energy range in a solid where no electron states exist, i.e. an energy range where the density of states vanishes.
Especially in condensed-matter physics, an energy gap is often known more abstractly as a spectral gap, a term which need not be specific to electrons or solids. |
Economic lot scheduling problem | The economic lot scheduling problem (ELSP) is a problem in operations management and inventory theory that has been studied by many researchers for more than 50 years. The term was first used in 1958 by professor Jack D. Rogers of Berkeley, who extended the economic order quantity model to the case where there are several products to be produced on the same machine, so that one must decide both the lot size for each product and when each lot should be produced. The method illustrated by Jack D. Rogers draws on a 1956 paper from Welch, W. Evert. The ELSP is a mathematical model of a common issue for almost any company or industry: planning what to manufacture, when to manufacture and how much to manufacture. |

Inositol 1-methyltransferase | In enzymology, an inositol 1-methyltransferase (EC 2.1.1.40) is an enzyme that catalyzes the chemical reaction S-adenosyl-L-methionine + myo-inositol ⇌ S-adenosyl-L-homocysteine + 1D-1-O-methyl-myo-inositolThus, the two substrates of this enzyme are S-adenosyl methionine and myo-inositol, whereas its two products are S-adenosylhomocysteine and 1D-1-O-methyl-myo-inositol.
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:1D-myo-inositol 1-O-methyltransferase. Other names in common use include inositol D-1-methyltransferase, S-adenosylmethionine:myo-inositol 3-methyltransferase, myo-inositol 3-O-methyltransferase, inositol 3-O-methyltransferase (name based on 1L-numbering system, and not 1D-numbering), and S-adenosyl-L-methionine:myo-inositol 3-O-methyltransferase. This enzyme participates in inositol phosphate metabolism. |

It is a direct upgrade to its predecessors, Windows 2000 for high-end and business users and Windows Me for home users, and is available for any devices running Windows NT 4.0, Windows 98, Windows 2000, or Windows Me that meet the new Windows XP system requirements. |
D bit cutter | A D bit cutter is a specialty bit in the shape of a "D" when looking from above. Often used to make precision holes using a lathe. This type of drill was first used in the early manufacture of muskets and other artifacts requiring a long straight holes in the days before modern accurate machines were available." |
Fixed station | Fixed station (also. fixed radio station) is a station in the fixed service. Each station is classified by the service in which it operates permanently or temporarily. |
Trolleytruck | A trolleytruck (also known as a freight trolley or trolley truck) is a trolleybus-like vehicle used for carrying cargo instead of passengers. A trolleytruck is usually a type of electric truck powered by two overhead wires, from which it draws electricity using two trolley poles. Two current collectors are required in order to supply and return current, because the return current cannot pass to the ground (as is done by streetcars on rails) since trolleytrucks use tires that are insulators. Lower powered trucks, such as might be seen on the streets of a city, tend to use trolley poles for current collection. Higher powered trucks, such as those used for large construction or mining projects, may exceed the power capacity of trolley poles and have to use pantographs instead. Trolleytrucks have been used in various places around the world and are still in use in cities in Russia and Ukraine, as well as at mines in North America and Africa. Because they draw power from the mains, trolleytrucks can use renewable energy sources – modern trolleytrucks systems are under test in Sweden and Germany along highways using diesel–electric hybrids to reduce emissions. |
Submarine landslide | Submarine landslides are marine landslides that transport sediment across the continental shelf and into the deep ocean. A submarine landslide is initiated when the downwards driving stress (gravity and other factors) exceeds the resisting stress of the seafloor slope material, causing movements along one or more concave to planar rupture surfaces. Submarine landslides take place in a variety of different settings, including planes as low as 1°, and can cause significant damage to both life and property. Recent advances have been made in understanding the nature and processes of submarine landslides through the use of sidescan sonar and other seafloor mapping technology. |
Cyclorama | A cyclorama is a panoramic image on the inside of a cylindrical platform, designed to give viewers standing in the middle of the cylinder a 360° view, and also a building designed to show a panoramic image. The intended effect is to make viewers, surrounded by the panoramic image, feel as if they were standing in the midst of the place depicted in the image. |

Software Industry Survey | The Software Industry Survey is an annual, for-the-public scientific survey about the size, composition, current state and future of the software industry and companies in Europe with origin in Finland.The survey organization is led (in 2010 and 2011) by the Software Business Lab research group of the BIT research centre at Aalto University, School of Science and Technology (former Helsinki University of Technology) with the help of several industry partners. Researchers from the Helsinki University of Technology and Centres of Expertise first organized this survey in 1997 to provide an overview of the Finnish software industry with financing mainly from the National Technology Agency (Tekes) and the Finnish Ministry of Trade and Industry. The 2011 Finnish survey received responses from 506 participants which is a bit smaller than 2010 due to more strict selection criteria. Surveys analysing the industry in other European countries than Finland are run by research partners. In 2011 the survey was implemented in Austria and Germany.The published reports by the survey group cover current economic impacts on the software industry (like the crises in 2009/2010 or Nokia’s changes for its mobile platform in 2011) on roughly 100 pages. Starting with the 2009 report, all included images and tables can be re-used under the free Creative Commons Attribution license version 3.0.Apart from these reports, the survey's data is used as input for various scientific studies based on the collected data. Results are also used by media companies like newspapers as source for news articles. |
Nearest neighbour algorithm | The nearest neighbour algorithm was one of the first algorithms used to solve the travelling salesman problem approximately. In that problem, the salesman starts at a random city and repeatedly visits the nearest city until all have been visited. The algorithm quickly yields a short tour, but usually not the optimal one. |
Tankhouse | A tankhouse (also spelled tank house or tank-house) is a water tower enclosed by siding. Tankhouses were part of a self-contained domestic water system supplying the house and garden, developed before the advent of electricity and municipal water mains. The system consisted of a windmill, a hand-dug well and the tankhouse. The windmill pumped water from the well up into the tank at the top of the tankhouse, from where it flowed down under gravity pressure to the house and garden. The system used no fuel or electricity; today it would be called green or eco-friendly. |
Rustlers (convenience food) | Rustlers are a range of hamburgers and hot sandwiches made by Kepak, a company based in Dublin, Ireland. Each product in the range comes packed with a sachet of sauce appropriate for the food. Several products are now also packaged with a slice of processed cheese and/or a rasher of bacon. |
Insafe | Insafe is a European network of Awareness Centres promoting safer and better usage of internet. It is co-funded by the Safer Internet Plus Programme. |
Web Feature Service | In computing, the Open Geospatial Consortium Web Feature Service (WFS) Interface Standard provides an interface allowing requests for geographical features across the web using platform-independent calls. One can think of geographical features as the "source code" behind a map, whereas the WMS interface or online tiled mapping portals like Google Maps return only an image, which end-users cannot edit or spatially analyze. The XML-based GML furnishes the default payload-encoding for transporting geographic features, but other formats like shapefiles can also serve for transport. In early 2006 the OGC members approved the OpenGIS GML Simple Features Profile. This profile is designed both to increase interoperability between WFS servers and to improve the ease of implementation of the WFS standard. |
Volume (thermodynamics) | In thermodynamics, the volume of a system is an important extensive parameter for describing its thermodynamic state. The specific volume, an intensive property, is the system's volume per unit of mass. Volume is a function of state and is interdependent with other thermodynamic properties such as pressure and temperature. For example, volume is related to the pressure and temperature of an ideal gas by the ideal gas law. |
Intravitreal injection | Intravitreal injection is the method of administration of drugs into the eye by injection with a fine needle. The medication will be directly applied into the vitreous humor. It is used to treat various eye diseases, such as age-related macular degeneration (AMD), diabetic retinopathy, and infections inside the eye such as endophthalmitis. As compared to topical administration, this method is beneficial for a more localized delivery of medications to the targeted site, as the needle can directly pass through the anatomical eye barrier (e.g. cornea, conjunctiva and lens) and dynamic barrier (e.g. tears and aqueous humor). It could also minimize adverse drug effects on other body tissues via the systemic circulation, which could be a possible risk for intravenous injection of medications. Although there are risks of infections or other complications, with suitable precautions throughout the injection process, chances for these complications could be lowered. |
Fuzhou Transliteration Scheme | The Fuzhou Transliteration Scheme (Chinese: 福州话拼音方案; pinyin: Fúzhōuhuà Pīnyīn Fāng'àn) refers to the romanization scheme published in 1994 for the Fuzhou Dialect Dictionary (Chinese: 福州方言词典; pinyin: Fúzhōu fāngyán cídiǎn), romanizing the Fuzhou dialect. It does not explicitly state the tones. |
PHOX2A | Paired mesoderm homeobox protein 2A is a protein that in humans is encoded by the PHOX2A gene. |
Essential dermatitis | Essential dermatitis is an idiopathic inflammation of the skin that does not fit the picture of other well defined conditions (such as atopic or contact dermatitis) and is a diagnosis of exclusion. |
FurryBall | FurryBall is 3D computer graphics software and plug-in for real-time GPU production quality unbiased rendering. It is also a biased final frame renderer used for many short and full length animated movies. FurryBall was used for rendering the feature animated movie Goat story with Cheese - it was probably the first world feature animated movie rendered completely only on GPU in 2012. |
Fucosidase | Tissue alpha-L-fucosidase is an enzyme that in humans is encoded by the FUCA1 gene.Alpha-Fucosidase is an enzyme that breaks down fucose.Fucosidosis is an autosomal recessive lysosomal storage disease caused by defective alpha-L-fucosidase with accumulation of fucose in the tissues. Different phenotypes include clinical features such as neurologic deterioration, growth retardation, visceromegaly, and seizures in a severe early form; coarse facial features, angiokeratoma corporis diffusum, spasticity and delayed psychomotor development in a longer surviving form; and an unusual spondylometaphyseoepiphyseal dysplasia in yet another form.[supplied by OMIM] |
Timeline of Carboniferous research | This timeline of Carboniferous research is a chronological listing of events in the history of geology and paleontology focused on the study of earth during the span of time lasting from 358.9 to 298.9 million years ago and the legacies of this period in the rock and fossil records. |
Internet leak | An internet leak is the unauthorized release of information over the internet. Various types of information and data can be, and have been, "leaked" to the Internet, the most common being personal information, computer software and source code, and artistic works such as books or albums. For example, a musical album is leaked if it has been made available to the public on the Internet before its official release date. |
D-xylose 1-dehydrogenase (NADP+) | In enzymology, a D-xylose 1-dehydrogenase (NADP+) (EC 1.1.1.179) is an enzyme that catalyzes the chemical reaction D-xylose + NADP+ ⇌ D-xylono-1,5-lactone + NADPH + H+Thus, the two substrates of this enzyme are D-xylose and NADP+, whereas its 3 products are D-xylono-1,5-lactone, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is D-xylose:NADP+ 1-oxidoreductase. Other names in common use include D-xylose (nicotinamide adenine dinucleotide phosphate), dehydrogenase, D-xylose-NADP+ dehydrogenase, D-xylose:NADP+ oxidoreductase, and D-xylose 1-dehydrogenase (NADP+). |
Tape correction (surveying) | In surveying, tape correction(s) refer(s) to correcting measurements for the effect of slope angle, expansion or contraction due to temperature, and the tape's sag, which varies with the applied tension. Not correcting for these effects gives rise to systematic errors, i.e. effects which act in a predictable manner and therefore can be corrected by mathematical methods. |
Helicon Photo Safe | Helicon Photo Safe is a proprietary freeware and commercial digital image organization and protection tool produced by Helicon Soft Ltd. It is designed to be an image viewer and organizer which works together with the editing program Helicon Filter, as well as an image encryption tool. It is intended to be integrated into the future Helicon Filter 5. |
Iron deficiency | Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen enzyme reactions in various tissues. Too little iron can interfere with these vital functions and lead to morbidity and death.Total body iron averages approximately 3.8 g in men and 2.3 g in women. In blood plasma, iron is carried tightly bound to the protein transferrin. There are several mechanisms that control iron metabolism and safeguard against iron deficiency. The main regulatory mechanism is situated in the gastrointestinal tract. The majority of iron absorption occurs in the duodenum, the first section of the small intestine. A number of dietary factors may affect iron absorption. When loss of iron is not sufficiently compensated by intake of iron from the diet, a state of iron deficiency develops over time. When this state is uncorrected, it leads to iron-deficiency anemia, a common type of anemia. Before anemia occurs, the medical condition of iron deficiency without anemia is called latent iron deficiency (LID). |
Ploy (board game) | Ploy is an abstract strategy board game for two or four players, played on a 9x9 board with a set of 15 pieces (2-handed) or 9 pieces (4-handed and partnership games) per player. Pieces have various horizontal, vertical or diagonal moves somewhat like chess pieces, except directions of movement are limited; pieces change directions of movement by "rotating". Object of the game is to capture the opponent's Commander (analogous to the king in chess), or all of his other pieces. |
Indolequinones | Indolequinones are molecules which are based upon an indole but have two additional ketone groups (quinone) attached to the ring structure.
This simple indolequinone indole-5,6-quinone is produced during the ripening of some fruit.
Other examples of indolequinones and the related mitosenes include natural compound mitomycin and the related chemotherapeutic agent apaziquone. |
EyeToy: Monkey Mania | EyeToy: Monkey Mania, also known as Saru Eye Toy Ōsawagi! Wakki Waki Game Tenkomori!! (サルアイトーイ 大騒ぎ！ウッキウキゲームてんこもり!!, Saru Ai Tōi Ōsawagi! Wakki Waki Gēmu Tenkomori!!, lit. "Monkey EyeToy Mania! Wakki Waki Game Extravaganza!!") in Asia, Japan, and Korea, is a party game based on the Ape Escape franchise that requires the EyeToy camera peripheral to play. The game consists of the franchise's titular monkeys engaging in minigames, with multiplayer for up to four players. The title was sold as a standalone game, and also in a bundle with a silver-colored EyeToy peripheral. |
Testosterone phenylbutyrate | Testosterone phenylbutyrate, also known as testosterone phenylbutanoate, testosterone 17β-phenylbutyrate, and androst-4-en-17β-ol-3-one 17β-phenylbutyrate, is a synthetic, injected anabolic-androgenic steroid (AAS) and an androgen ester – specifically, the C17β phenylbutyrate (phenylbutanoate) ester of testosterone – which was never marketed. It is a prodrug of testosterone and, when administered via intramuscular injection, is associated with a long-lasting depot effect and extended duration of action. |
Monoamine releasing agent | A monoamine releasing agent (MRA), or simply monoamine releaser, is a drug that induces the release of a monoamine neurotransmitter from the presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitter. Many drugs induce their effects in the body and/or brain via the release of monoamine neurotransmitters, e.g., trace amines, many substituted amphetamines, and related compounds. |
Ribbon cable | A ribbon cable (also known as multi-wire planar cable) is a cable with many conducting wires running parallel to each other on the same flat plane. As a result, the cable is wide and flat. Its name comes from its resemblance to a piece of ribbon.Ribbon cables are usually seen for internal peripherals in computers, such as hard drives, CD drives and floppy drives. On some older computer systems (such as the BBC Micro and Apple II series) they were used for external connections as well. The ribbon-like shape interferes with computer cooling by disrupting airflow within the case and also makes the cables awkward to handle, especially when there are a lot of them; as a result, round cables have almost entirely replaced ribbon cables for external connections and are increasingly being used internally as well. |
Till | Till or glacial till is unsorted glacial sediment.
Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines.
Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. |
Diverticulosis | Diverticulosis is the condition of having multiple pouches (diverticula) in the colon that are not inflamed. These are outpockets of the colonic mucosa and submucosa through weaknesses of muscle layers in the colon wall. Diverticula do not cause symptoms in most people. Diverticular disease occurs when diverticula become clinically inflamed, a condition known as diverticulitis.Diverticula typically occur in the sigmoid colon, which is commonplace for increased pressure. The left side of the colon is more commonly affected in the United States while the right side is more commonly affected in Asia. Diagnosis is often during routine colonoscopy or as an incidental finding during CT scan.It is common in Western countries with about half of those over the age of 60 affected in Canada and the United States. Diverticula are uncommon before the age of 40, and increase in incidence beyond that age. Rates are lower in Africa; the reasons for this remain unclear but may involve the greater prevalence of a high fiber diet in contrast with the lower-fiber diet characteristic of many Western populations. |
Hypergeometric identity | In mathematics, hypergeometric identities are equalities involving sums over hypergeometric terms, i.e. the coefficients occurring in hypergeometric series. These identities occur frequently in solutions to combinatorial problems, and also in the analysis of algorithms. These identities were traditionally found 'by hand'. There exist now several algorithms which can find and prove all hypergeometric identities. |
Equation-free modeling | Equation-free modeling is a method for multiscale computation and computer-aided analysis. It is designed for a class of complicated systems in which one observes evolution at a macroscopic, coarse scale of interest, while accurate models are only given at a finely detailed, microscopic, level of description. The framework empowers one to perform macroscopic computational tasks (over large space-time scales) using only appropriately initialized microscopic simulation on short time and small length scales. The methodology eliminates the derivation of explicit macroscopic evolution equations when these equations conceptually exist but are not available in closed form; hence the term equation-free. |
Hysterotomy | A hysterotomy is an incision made in the uterus. This surgical incision is used in several medical procedures, including during termination of pregnancy in the second trimester (or abortion) and delivering the fetus during caesarean section. It is also used to gain access and perform surgery on a fetus during pregnancy to correct birth defects, and it is an option to achieve resuscitation if cardiac arrest occurs during pregnancy and it is necessary to remove the fetus from the uterus. |
RIOT wheel | A RIOT wheel is a one-wheeled vehicle, or monowheel. Housing a motor and counterweight inside a giant wheel, the driver sits on a platform that extends out in front of the device. This is in contrast to the typical monowheels and their long history, where the rider sits inside the wheel. |
Stereoscopic spectroscopy | Stereoscopic spectroscopy is a type of imaging spectroscopy that can extract a few spectral parameters over a complete image plane simultaneously. A stereoscopic spectrograph is similar to a normal spectrograph except that (A) it has no slit, and (B) multiple spectral orders (often including the non-dispersed zero order) are collected simultaneously. The individual images are blurred by the spectral information present in the original data. The images are recombined using stereoscopic algorithms similar to those used to find ground feature altitudes from parallax in aerial photography. Stereoscopic spectroscopy is a special case of the more general field of tomographic spectroscopy. Both types of imaging use an analogy between the (x,y,λ) data space of imaging spectrographs and the conventional (x,y,z) 3-space of the physical world. Each spectral order in the instrument produces an image plane analogous to the view from a camera with a particular look angle through the (x,y,λ) data space, and recombining the views allows recovery of (some aspects of) the spectrum at every location in the image. |
