Grumman had been working on a successor to the F4F Wildcat since 1938, and the contract for the prototype XF6F-1 was signed on 30 June 1941. The aircraft was originally designed to use the Wright R-2600 Twin Cyclone two-row, 14-cylinder radial engine of (the same engine used with Grumman's then-new torpedo bomber under development), driving a three-bladed Curtiss Electric propeller. Instead of the Wildcat's narrow-track, hand-cranked, main landing gear retracting into the fuselage inherited from the F3F ( a design from the 1930s Grumman FF-1 fighter biplane), the Hellcat had wide-set, hydraulically actuated landing-gear struts that rotated through 90° while retracting backwards into the wings, but with full wheel doors fitted to the struts that covered the entire strut and the upper half of the main wheel when retracted, and twisted with the main gear struts through 90° during retraction. The wing was mounted lower on the fuselage and was able to be hydraulically or manually folded, with each panel outboard of the undercarriage bay folding backwards from pivoting on a specially oriented, Grumman-patented "Sto-Wing" diagonal axis pivoting system much like the earlier F4F, with a folded stowage position parallel to the fuselage with the leading edges pointing diagonally down.

A very general feature of Webern's music, as much of Schoenberg's, is a predilection toward the use of minor seconds, major sevenths, and minor ninths, as noted with some insight in 1934 by microtonalist Alois Hába, writing of his and his students' affinities with Schoenberg in particular, and later by both Valentina Kholopova and Yuri Kholopov in formulations more specific to Webern and with a more unifying emphasis on the semitone in the context of axial inversional symmetry and octave equivalence (i.e., interval class 1, or ic1), approaching Allen Forte's more generalizing pitch-class set analysis. Webern's consistent and distinctive use of ic1 in particular within small subsets of other intervals, sometimes derived from a given twelve-tone row in his later practice, was well noted. Webern often musically expresses ic1 as a major seventh, minor ninth, or even wider interval. Webern's intervallic practices may be more globally understood as the outcome of a inversionally symmetrical treatment of pitch in a manner comparable to other modernists, including Berg, Bartók, Debussy, Schoenberg, and Stravinsky, or more nascently even Liszt and Wagner, but often far more strictly and increasingly in schemes with other parameters (e.g., fixed or "frozen" register, the association of articulations and dynamics with specific pitches).

With reported vent temperatures of , "phase separation" has been inferred to occur within fluids beneath the field. Differing ratios of brine and vapour phases have been used to characterize geochemistry at sites such as "Bastille" and "Dante". High temperatures also allow metals to stay in solution, allowing for distinctive black-smoker chimneys. Through a combination of targeted, high-temperature (350 °C) venting and diffuse, low-temperature (10-25 °C) venting, the Main Endeavour field alone produces a total heat flux of 650±100 megawatts (MW). According to their thermal, particle, and chemical anomalies, vent plumes rise 50 to 350 metres above the seafloor to a level of neutral buoyancy. While the plumes rising above the ridge crests are free to drift with the ambient flow, the deeper portions of the plumes may remain stuck inside the valley.

The reactivity of niobium with oxygen requires it to be worked in a vacuum or inert atmosphere, which significantly increases the cost and difficulty of production. Vacuum arc remelting (VAR) and electron beam melting (EBM), novel processes at the time, enabled the development of niobium and other reactive metals. The project that yielded C-103 began in 1959 with as many as 256 experimental niobium alloys in the "C-series" (C arising possibly from columbium) that could be melted as buttons and rolled into sheet. Wah Chang Corporation had an inventory of hafnium, refined from nuclear-grade zirconium alloys, that it wanted to put to commercial use. The 103rd experimental composition of the C-series alloys, Nb-10Hf-1Ti, had the best combination of formability and high-temperature properties. Wah Chang fabricated the first 500 lb heat of C-103 in 1961, ingot to sheet, using EBM and VAR. The intended applications included turbine engines and liquid metal heat exchangers. Competing niobium alloys from that era included FS85 (Nb-10W-28Ta-1Zr) from Fansteel Metallurgical Corp., Cb129Y (Nb-10W-10Hf-0.2Y) from Wah Chang and Boeing, Cb752 (Nb-10W-2.5Zr) from Union Carbide, and Nb1Zr from Superior Tube Co.

Desmond Paul Henry (1921–2004) was a Manchester University Lecturer and Reader in Philosophy (1949–82). He was one of the first British artists to experiment with machine-generated visual effects at the time of the emerging global computer art movement of the 1960s (The Cambridge Encyclopaedia 1990 p. 289; Levy 2006 pp. 178–180). During this period, Henry constructed a succession of three electro-mechanical drawing machines from modified bombsight analogue computers which were employed in World War II bombers to calculate the accurate release of bombs onto their targets (O'Hanrahan 2005). Henry's machine-generated effects resemble complex versions of the abstract, curvilinear graphics which accompany Microsoft's Windows Media Player. Henry's machine-generated effects may therefore also be said to represent early examples of computer graphics: "the making of line drawings with the aid of computers and drawing machines" (Franke 1971, p. 41).

Proteorhodopsin variants are not spread randomly, but disperse along depth gradients based on the maximal absorption-tuning of the particular holoprotein sequence; this is mainly due to the electromagnetic absorption by water which creates wavelength gradients relative to depth. Oxyrrhis marina is a Dinoflagellate protist with green-absorbing proteorhodopsin (a result of the L109 Group) that exists mostly in shallow tide pools and shores, where green light is still available. Karlodinium micrum, another dinolagelate, expresses a blue tuned proteorhodopsin (E109) which may be related to its deep water vertical migrations. O.Marina was originally believed to be a heterotroph, however the proteorhodopsin may well partake in a functionally significant manner, as it was the most abundantly expressed nuclear gene and, furthermore, is dispersed unevenly in the organism, suggesting some organelle membrane function. Previously the only eukaryotic solar energy transducing proteins were Photosystem I and Photosystem II. It has been hypothesized that lateral gene transfer is the method by which proteorhodopsin has made its way into numerous phyla. Bacteria, archea and eukarya all colonize the photic zone where they come to light; Proteorhodopsin has been able to disseminate through this zone, but not to other portions of the water column.

Before 1998, universities were funded mainly by central government, although they have been increasingly reliant on charging students and seeking to raise private capital. First, universities have the power to generate income through endowment trust funds, accumulated over generations of donations and investment. Second, under the Further and Higher Education Act 1992 there are funding councils paid for through general taxation for England, Wales, Scotland and Northern Ireland. For England and Wales, the Secretary of State appoints 12 to 15 members and the chair, of which 6 to 9 should be academics and the remainder with "industrial, commercial or financial" backgrounds. Funds are administered at the councils' discretion but must consult with "bodies representing the interests of higher education institutions" such as the University and College Union and Universities UK. After the Higher Education and Research Act 2017, the English council from 2018 will be renamed the "Office for Students". Further, there are seven research councils (AHRC, ESRC, MRC, etc.) which distribute funds after peer review of applications by academics conducting research.

After launching, the sisters were transferred to Kronstadt for fitting out as the shallow waters around Saint Petersburg prevented deep-draft ships from being completed. This added more delays as the dockyard there lacked the equipment to efficiently fit out the ships. Both ships were assigned to the Baltic Fleet upon completion and they were not fully equipped until around 1872. The monitor accidentally rammed "Admiral Lazarev" in Kronstadt harbor on 22 October 1871. The former was only slightly damaged, but the latter had a hole punched in its hull. Water poured in and the ship took on a list of 8° and nearly capsized before other ships in the harbor could use their pumps to reduce the flooding. The ship's watertight bulkheads proved to be poorly caulked and sealed and the commission that investigated the accident recommended that the bulkheads be tested during construction by intentionally flooding them. The Navy ignored this recommendation, which directly led to the loss of the coast-defense ship in 1897. Another recommendation which was followed was to attach all of the ship's pumps to the bilges to allow a flooded compartment to be pumped out as quickly as possible. This modification was tested aboard "Admiral Lazarev"in 1872 and became standard practice for the navy.

The 19th century saw a fragmentation of English architecture, as Classical forms continued in widespread use but were challenged by a series of distinctively English revivals of other styles, drawing chiefly on Gothic, Renaissance and vernacular traditions but incorporating other elements as well. This ongoing historicism was counterposed by a resumption of technical innovation, which had been largely in abeyance since the Renaissance but was now fuelled by new materials and techniques derived from the Industrial Revolution, particularly the use of iron and steel frames, and by the demand for new types of building. The rapid growth and urbanisation of the population entailed an immense amount of new domestic and commercial construction, while the same processes combined with a religious revival to bring about a resumption of widespread church building. Mechanised manufacturing, railways and public utilities required new forms of building, while the new industrial cities invested heavily in grand civic buildings and the huge expansion and diversification of educational, cultural and leisure activities likewise created new demands on architecture.

During this time, the reproductive females will raise two separate generations of broods, one that is reared by the mother, and the second which is reared by both surviving mothers and their daughters (which originated from the first brood). However, the number of broods that are initiated depends on climate conditions. For example, if it is rainy rather than dry, only one brood will be raised rather than two (which is more typical). Furthermore, if new nests are created, it typically happens between the first and second brood initiations. In this way, the colony initiation cycle and nesting cycle are in rotation with one another. Once the eggs have been laid, the egg-laying females will construct individual brood cells, each with a certain amount of nectar and pollen. This pollen is rolled into a small ball, and the egg is laid on top of the ball before the cell is sealed. Differences in the size of these pollen balls (which are the only food that is provided to the growing larvae) is thought to contribute to differences in weight for adults. The pupal stage lasts 18 days alone, however the full cycle spans approximately 6 weeks. Colony decline happens during the summer months between the end of egg production and overwintering. However, because the females of "L. hemichalceum" migrate between different nests, more than one nest exists at a time.

Lepidosaur herbivory describes herbivorous lepidosaurs. Living non-avian reptiles form a paraphyletic group that consists of over 9,000 species of crocodiles, turtles, and lepidosaurs. The most diverse group, Lepidosauria, is first known from the Middle Triassic (240 million years ago) fossils, but likely originated in the Permian (approximately 300-250 million years ago). Living lepidosaurs, which include snakes, lizards, and rhynchocephalians, occupy a wide range of environments and niches. The lepidosaurs have many similar anatomical morphology like transverse cloaca, distal tongue, superficial teeth attachment, fused pelvic bones etc. Though widely viewed as obligate carnivores, a small number of lepidosaurs are known to consume plant material. For example, there are roughly 3,300 species of living lizards and approximately 3% of them eat at least some plants. Though the exact definition of herbivory varies significantly between scientists, most define herbivorous lepidosaurs as those that consume plants for approximately 70-90% of its diet.

Many evaluation criteria apply globally to an entire experimental structure, most notably the resolution, the anisotropy or incompleteness of the data, and the residual or R-factor that measures overall model-to-data match (see below). Those help a user choose the most accurate among related Protein Data Bank entries to answer their questions. Other criteria apply to individual residues or local regions in the 3D structure, such as fit to the local electron density map or steric clashes between atoms. Those are especially valuable to the structural biologist for making improvements to the model, and to the user for evaluating the reliability of that model right around the place they care about - such as a site of enzyme activity or drug binding. Both types of measures are very useful, but although global criteria are easier to state or publish, local criteria make the greatest contribution to scientific accuracy and biological relevance. As expressed in the Rupp textbook, "Only local validation, including assessment of both geometry and electron density, can give an accurate picture of the reliability of the structure model or any hypothesis based on local features of the model."

One of the most prominent cases of doping at the Olympics, and in sport as a whole, occurred during the 1988 Seoul Olympics. Ben Johnson entered the race as the reigning 100 metres world record holder and won the Olympic final, raising his arm in victory, in a new world record of 9.79 seconds to much fanfare. Soon after being awarded the gold medal the results of his post-race drug test revealed his urine contained traces of stanozolol (a banned steroid). Johnson later admitted to doping, but he and his coach Charlie Francis still claimed he had his drink spiked at the Olympics, as Johnson was taking a different type of steroid at the time. The positive test had long-lasting effects on public perception of the sport and advanced the case for more stringent drug testing. The Canadian government launched an investigation into drugs in sport, known as the Dubin Inquiry, the following year. The 1988 Olympic men's 100 metres final has been referred to as "the dirtiest race in history", as only two of the eight finalists remained free of doping issues during their careers.

By the mid-1930s, the institute was beginning to show "growing pains". Student enrollment grew by almost 60% from 1933 to 1937 while funding from the state increased by only 17% during the same period. The on-campus dormitories and dining hall struggled to meet the needs of the growing student body. The situation was so bad that the Southern Association of Colleges and Secondary Schools, the school's accrediting agency, placed the school on probation in 1937. Among the factors cited by the agency were a high student-teacher ratio, crowded classrooms, library facilities that failed to meet the minimum standards, and a low teaching cost. Additional problems included turning away male students from admission into the agriculture department as a result of inadequate farm facilities and a decrease in the operating budget of the School of Engineering between 1933 and 1937 despite a 268% increase in student enrollment. After the probation was imposed on the school, the student body and Louisiana Polytechnic Institute President Edwin Richardson sought additional appropriations from the State legislature to expand the infrastructure at the school's campus.

Horizontal single axis trackers are typically used for large distributed generation projects and utility scale projects. The combination of energy improvement and lower product cost and lower installation complexity results in compelling economics in large deployments. In addition the strong afternoon performance is particularly desirable for large grid-tied photovoltaic systems so that production will match the peak demand time. Horizontal single axis trackers also add a substantial amount of productivity during the spring and summer seasons when the Sun is high in the sky. The inherent robustness of their supporting structure and the simplicity of the mechanism also result in high reliability which keeps maintenance costs low. Since the panels are horizontal, they can be compactly placed on the axle tube without danger of self-shading and are also readily accessible for cleaning.

Jeremy Estes, an early reviewer from PopMatters, notes the difficulty in revamping the character Superman in his review of the first issue of the series. The "All-Star" continuity allowed the writer Grant Morrison much more writing freedom. Frank Quitely's art is praised as "fresh and modern", while still "evoking the classic hero known around the world". At the time of writing only the first issue had been released, and so Estes was unsure of the direction of the story, noting the creative team "have set up a promising tale, but only time will tell if they take the last train to Memphis or head West, all the way to Vegas". Nicholas Labarre, writing for Sequart, argued that "All-Star Superman" "confidently exploits the near omnipotence of the main character" in contrast with other Superman stories. He compared the series favorably with Morrison's other work. Ed Mathews from PopImage reviewed the first collected trade paperback, which collects the first six issues, and praised the creative team, stating the art is "the most elegant work out of Frank Quitely I've seen to date". Mathews also singled out Grant Morrison's, saying that the series adds to the Superman mythos "by tweaking bits and parts from the character's rich history just enough to make old concepts fresh again". He recommended Volume 1 of the collected editions, and stated that ""All Star Superman" sings a hit". Another review of Volume 1 came from Danny Graydon of "The First Post", who stated that Grant Morrison's writing is "the most vigorously entertaining take on the "Man of Steel" in decades" and that the "nuanced artwork is to be savoured".

In December 1940, Chuikov was appointed the chief Soviet military representative to the Republic of China and adviser to Chiang Kai-shek, the Nationalist leader, in Chongqing. Prior to his departure for China, he was summoned to meet Joseph Stalin and Semyon Timoshenko, who instructed him to ensure that China remain engaged in the war with Japan so Japan could not challenge the Soviet Union in the Far East and allow the Soviet Union to focus on the German threat from the West. Stalin told Chuikov to prioritize support for Nationalists over the Chinese Communists so as to ensure Chinese unity against Japan. Chuikov arrived in China with a large supply of Soviet armaments for the Nationalist Army, including tanks, artillery, fighter and bomber aircraft, and trucks. In January 1941 when the Nationalists attacked the Communists in the Southern Anhui Incident in breach of their nominal alliance, Chuikov was criticized by Mao Zedong for failing to stop Chiang's aggression against the Chinese Communists. Chuikov insisted that the Nationalists could not use Soviet weaponry against the Communists, met with Communist leaders Zhou Enlai and Ye Jianying, but in keeping with Stalin's directives, continued to support the Nationalist war effort against Japan, even after the signing of the Soviet–Japanese Neutrality Pact in April 1941. In the Second Battle of Changsha in September 1941, he advised Chiang to relieve the Japanese siege on Changsha by attacking the strategic city of Yichang some 400 km to the north, and the strategy succeeded. In March 1942, he was recalled to the USSR, which by then was at war with Germany.

All animals and plants form associations with microorganisms, including protists, bacteria, archaea, fungi, and viruses. In the ocean, animal–microbial relationships were historically explored in single host–symbiont systems. However, new explorations into the diversity of microorganisms associating with diverse marine animal hosts is moving the field into studies that address interactions between the animal host and the multi-member microbiome. The potential for microbiomes to influence the health, physiology, behaviour, and ecology of marine animals could alter current understandings of how marine animals adapt to change. This applies to especially the growing climate-related and anthropogenic-induced changes already impacting the ocean. The plant microbiome plays key roles in plant health and food production and has received significant attention in recent years. Plants live in association with diverse microbial consortia, referred to as the plant microbiota, living both inside (the endosphere) and outside (the episphere) of plant tissues. They play important roles in the ecology and physiology of plants. The core plant microbiome is thought to contain keystone microbial taxa essential for plant health and for the fitness of the plant holobiont. Likewise, the mammalian gut microbiome has emerged as a key regulator of host physiology, and coevolution between host and microbial lineages has played a key role in the adaptation of mammals to their diverse lifestyles.

William Forster (fl. 1630–1673) was an English mathematician living in London, a pupil of the celebrated mathematician and astronomer clergyman William Oughtred (1574-1660). He is best known for his book, a translation and edition of Oughtred's treatise entitled "The Circles of Proportion". Oughtred invented horizontal and circular forms of the slide rule, and Forster persuaded his master to let him translate his writings about their form and use, and to publish them. The publication resulted in a controversy, because another student of Oughtred's, Richard Delamain the elder, during the two years (1630-32) in which Forster was preparing the book, brought out two treatises on the same subject claiming the inventions as his own, and addressing himself to royal patronage. Forster's work was dedicated to that eminent intellectual, Sir Kenelm Digby (1603-1665), and the account of Oughtred's claim is found in Forster's "Preface", or "Letter of Dedication". Following the invention or discovery of logarithms by John Napier, in his "Mirifici Logarithmorum Canonis Descriptio" of 1614, the translation of that work by Edward Wright (1561-1615), and Henry Briggs's "Arithmetica Logarithmica" of 1624, the development of the slide rule had an important impact on the teaching of mathematics.

Signal enhancement by extravascular water protons, or SEEP, is a contrast mechanism for functional magnetic resonance imaging (fMRI), which is an alternative to the more commonly employed BOLD (blood-oxygen-level dependent) contrast. This mechanism for image contrast changes corresponding to changes in neuronal activity was first proposed by Dr. Patrick Stroman in 2001. SEEP contrast is based on changes in tissue water content which arise from the increased production of extracellular fluid and swelling of neurons and glial cells at sites of neuronal activity. Because the dominant sources of MRI signal in biological tissues are water and lipids, an increase in tissue water content is reflected by a local increase in MR signal intensity. A correspondence between BOLD and SEEP signal changes, and sites of activity, has been observed in the brain and appears to arise from the common dependence on changes in local blood flow to cause a change in blood oxygenation or to produce extracellular fluid. The advantage of SEEP contrast is that it can be detected with MR imaging methods which are relatively insensitive to magnetic susceptibility differences between air, tissues, blood, and bone. Such susceptibility differences can give rise to spatial image distortions and areas of low signal, and magnetic susceptibility changes in blood give rise to the BOLD contrast for fMRI. The primary application of SEEP to date has been fMRI of the spinal cord (spinal fMRI) because the bone/tissue interfaces around the spinal cord cause poor image quality with conventional fMRI methods. The disadvantages of SEEP compared to BOLD contrast are that it reveals more localized areas of activity, and in the brain the signal intensity changes are typically lower, and it can therefore be more difficult to detect.

The General Atomics HTGR design features a fully passive and inherently safe decay heat removal system, termed the Reactor Cavity Cooling System (RCCS). In this design, an array of steel ducts line the concrete containment (and hence surround the reactor pressure vessel) which provide a flow path for air driven natural circulation from chimneys positioned above grade. Derivatives of this RCCS concept (with either air or water as the working fluid) has also been featured in other gas-cooled reactor designs, including the Japanese High-temperature engineering test reactor, the Chinese HTR-10, the South African PBMR, and the Russian GT-MHR. While none of these designs have been commercialized for power generation research in these areas is active, specifically in support of the Generation IV initiative and NGNP programs, with experimental facilities at Argonne National Laboratory (home to the Natural convection Shutdown heat removal Test Facility, a 1/2 scale air-cooled RCCS) and the University of Wisconsin (home to separate 1/4 scale air and water-cooled RCCS).

Solar energy conversion can impact not only just individual customers but whole communities. In a growing number of neighborhoods across America, the conventional model of independent, non-connected rooftop installations is being replaced by community-sized solar microgrids. The idea of “community solar” first became popular because of issues regarding energy storage. Because as of 2018 the wide-scale production of lithium-ion battery and other storage technologies lags the progress of rooftop PV installations, a main issue preventing a nationwide shift to rooftop solar energy generation is the lack of a reliable, single-home storage system that would provide contingencies for night-time energy use, cloud cover, curtailments and blackouts. Additionally, financing solar installations for single homes may be more difficult to secure given a smaller project scope and lack of access to funds. A viable alternative is to connect blocks of homes together in a community microgrid, using more proven large storage installations, thus lowering barriers to solar adoption. In some cases, a microgrid “web” is made by connecting each independent rooftop PV house to a greater storage facility. Other designs, primarily where rooftop installations are not possible, feature a large combined solar array + storage facility located on an adjacent field. As an added social impact, this form of installation makes solar energy economically viable for multi-family homes and historically low income neighborhoods.

Catherine Driscoll, Melissa Gregg, Laurie Ouellette, and Julie Wilson refer to Jenkins' work in the 2011 special issue as part of their challenging of the larger framework of media convergence scholarship. They argue that the willing submission of the user to the corporate interests fuelling media convergence is also gendered as the logic of convergence, which is, to a large extent, informed by the logic of capitalism, albeit in an online environment, perpetuating the ongoing exploitation of women through a replication of the 'free' labour built into social expectations of women. And Richard Maxwell & Toby Miller in the same issue also reference Jenkins' work to critique the broader discourse of media convergence, arguing that the logic of convergence is one of ceaseless growth and innovation that inevitably preferences commercial over individual interests.(In Jenkins' 2014 response, he counters that throughout his scholarship he has emphasized collective agency not individual agency). Furthermore, Maxwell & Miller argue prevailing discussions of convergence have attended to the micro level of technological progress over the macro level of rampant economic exploitation, through concepts like 'playbour' (labour freely provided by users as they interact with the online world) resulting in a dominant focus on the Global North that ignores the often abhorrent material conditions of workers in the Global South who fuel the ongoing proliferation of digital capitalism.

Copper foil, at room temperature and very low pressure and in the presence of small amounts of methane produces high quality graphene. The growth automatically stops after a single layer forms. Arbitrarily large films can be created. The single layer growth is due to the low concentration of carbon in methane. The process is surface-based rather than relying on absorption into the metal and then diffusion of carbon into graphene layers on the surface. The room temperature process eliminates the need for postproduction steps and reduces production from a ten-hour/nine- to ten-step procedure to a single step that takes five minutes. A chemical reaction between the hydrogen plasma formed from the methane and ordinary air molecules in the chamber generates cyano radicals—carbon–nitrogen molecules without electrons. These charged molecules scour away surface imperfections, providing a pristine substrate. The graphene deposits form lines that merge into each other, forming a seamless sheet that contributes to mechanical and electrical integrity.

In his contribution „Historical perspectives on queries concerning photophosphorylation" Kandler describes the beginnings of photophosphorylation research and how he became interested: In 1948, he was inspired by a lecture on the phosphate metabolism of yeast by Feodor Lynen (1964 Nobel Prize in Physiology or Medicine). In these years, in the aftermath of World War II, the original Chemical Institute of the Ludwig Maximilian University of Munich was still in ruins and Feodor Lynen and his assistant Helmut Holzer were working temporarily as guests in the Botanical Institute just next door to the laboratory where Kandler was engaged in his thesis in botany. Kandler was impressed by the experimental methods in Lynen's laboratory and got acquainted with them; Holzer and Kandler became close friends. At that time, Holzer was able to present the first evidence for ATP formation in yeast oxidizing butanol to butyric acid. Kandler then decided to transfer their techniques to measuring phosphorylation rates "in vivo" to photosynthesis studies in "Chlorella".

Nihonium is the first member of the 7p series of elements and the heaviest group 13 element on the periodic table, below boron, aluminium, gallium, indium, and thallium. All the group 13 elements except boron are metals, and nihonium is expected to follow suit. Nihonium is predicted to show many differences from its lighter homologues. The major reason for this is the spin–orbit (SO) interaction, which is especially strong for the superheavy elements, because their electrons move much faster than in lighter atoms, at velocities close to the speed of light. In relation to nihonium atoms, it lowers the 7s and the 7p electron energy levels (stabilising those electrons), but two of the 7p electron energy levels are stabilised more than the other four. The stabilisation of the 7s electrons is called the inert pair effect, and the separation of the 7p subshell into the more and less stabilised parts is called subshell splitting. Computational chemists see the split as a change of the second, azimuthal quantum number "l", from 1 to 1/2 and 3/2 for the more and less stabilised parts of the 7p subshell, respectively. For theoretical purposes, the valence electron configuration may be represented to reflect the 7p subshell split as 7s 7p. The first ionisation energy of nihonium is expected to be 7.306 eV, the highest among the metals of group 13. Similar subshell splitting should exist for the 6d electron levels, with four being 6d and six being 6d. Both these levels are raised to be close in energy to the 7s ones, high enough to possibly be chemically active. This would allow for the possibility of exotic nihonium compounds without lighter group 13 analogues.

"SpaceChem" was generally well received by critics, with an aggregate Metacritic score of 84 out of 100 from its Microsoft Windows release. Quintin Smith of Rock, Paper, Shotgun said "I think we might have just received one of the year's best indie games in the first week of 2011". Gamasutra's Margaret Robertson praised "SpaceChem"s gameplay, contrasting it with other open-ended activities as it offers the opportunity for the player to be as creative as they want to be within the minimal ruleset required of each puzzle. Robertson also found the game to be thrilling, having each puzzle initially appear "so astonishingly dispiriting" to what she had previously learned, but through trial and error coming to a solution that works and giving her the feeling of having "made a creative statement" in her solution. Eurogamer's John Teti praised the means through which the game introduced new mechanics without excessive reliance on tutorials; he commented that "the problems become more daunting" through the addition of new elements and commands, the game "is always more accessible than it looks". "Edge" said "The triumph of "SpaceChem" is that overcoming these situations is more a case of inventing a solution than discovering one."

To validate the design, a programme of nuclear tests was required, which was estimated to cost around £5.9 million. This was authorised by Douglas-Home on 28 November 1963. A series of underground tests were carried out at the Nevada Test Site in the United States, starting with Whetstone/Cormorant on 17 July 1964. The next test, Whetstone/Courser on 25 September 1964 failed due to a fault in the American neutron initiators, and had to be repeated as Flintlock/Charcoal on 10 September 1965. This tested a design of the ET.317 using less plutonium. With four Polaris boats each carrying 16 missiles each with three warheads, there were 192 warheads in total. This modification therefore saved 166 kg of plutonium worth £2.5 million. Additional active materials required were obtained from the US. Some 5.37 tonnes of UK-produced plutonium was exchanged for 6.7 kg of tritium and 7.5 tonnes of highly enriched uranium between 1960 and 1979. Warhead manufacture commenced in December 1966.

The Etruscan shrew has a slender (not truncated) body, with a length between excluding the tail, which adds another . The body mass varies between and and is usually about . In comparison, the related greater white-toothed shrew can be twice as long and weighs four to five times more. The head is relatively large, with a long, mobile proboscis, and the hind limbs are relatively small. The ears are relatively large and protuberant. The Etruscan shrew has a very fast heart beating rate, up to 1511 beats/min (25 beats/s) and a relatively large heart muscle mass, 1.2% of body weight. The fur color on the back and sides is pale brown, but is light gray on the stomach. The fur becomes denser and thicker from fall through the winter. The shrew usually has 30 teeth, but the 4th upper intermediate tooth is very small (rudimentary), and is absent in some individuals. Near the mouth grow a dense array of short whiskers, which the shrew actively uses to search for prey, especially in the night. Dimorphism in body features between males and females is absent.

One of the key modifications over the standard 301 4-barrel was the 301 Turbo block. The 301T block was significantly more durable than the standard 301 block and received a thicker bottom end. This included the ESC (Electronic Spark Control) distributor and controller borrowed from the 301 Turbo, which allowed for higher timing without the penalty of engine damaging pinging or preignition. A larger ram air flex duct to the air cleaner from the left-hand fender, specific carburettor calibration for the Rochester Quadrajet, a "T/A 4.9" callout on the shaker, 60 psi oil pump, and cam similar in grind to the 400 from the 1978–1979 model year were also included. Unfortunately, there were no improvements in the casting number "01" small-valve high-velocity heads, which would have yielded greater improvements in power. Additionally, the 301 W72 never received the option to come equipped with a manual transmission like the standard 301 received in 1979, and disappointingly, production for all Pontiac V8's ended soon after as GM sought to "corporatize" engine production.

In 1928 Hale secured a grant of $6 million from the Rockefeller Foundation for "the construction of an observatory, including a 200-inch reflecting telescope" to be administered by the California Institute of Technology (Caltech), of which Hale was a founding member. In the early 1930s, Hale selected a site at on Palomar Mountain in San Diego County, California, US, as the best site, and less likely to be affected by the growing light pollution problem in urban centers like Los Angeles. The Corning Glass Works was assigned the task of making a primary mirror. Construction of the observatory facilities and dome started in 1936, but because of interruptions caused by World War II, the telescope was not completed until 1948 when it was dedicated. Due to slight distortions of images, corrections were made to the telescope throughout 1949. It became available for research in 1950.

To perform a study, the person is positioned within an MRI scanner that forms a strong magnetic field around the area to be imaged. First, energy from an oscillating magnetic field is temporarily applied to the patient at the appropriate resonance frequency. Scanning with X and Y gradient coils causes a selected region of the patient to experience the exact magnetic field required for the energy to be absorbed. The atoms are excited by a radio frequency (RF) pulse and the resultant signal is measured by a receiving coil. The RF signal may be processed to deduce position information by looking at the changes in RF level and phase caused by varying the local magnetic field using gradient coils. As these coils are rapidly switched during the excitation and response to perform a moving line scan, they create the characteristic repetitive noise of an MRI scan as the windings move slightly due to magnetostriction. The contrast between different tissues is determined by the rate at which excited atoms return to the equilibrium state. Exogenous contrast agents may be given to the person to make the image clearer.

Niels Steensen was born in Copenhagen on New Year's Day 1638 (Julian calendar), the son of a Lutheran goldsmith who worked regularly for King Christian IV of Denmark. He became ill at age three, suffering from an unknown disease, and grew up in isolation during his childhood. In 1644 his father died, after which his mother married another goldsmith. In 1654–1655, 240 pupils of his school died due to the plague. Across the street lived Peder Schumacher (who would offer Steensen a post as professor in Copenhagen in 1671). At the age of 19, Steensen entered the University of Copenhagen to pursue medical studies. After completing his university education, Steensen set out to travel through Europe; in fact, he would be on the move for the rest of his life. In the Netherlands, France, Italy and Germany he came into contact with prominent physicians and scientists. These influences led him to use his own powers of observation to make important scientific discoveries.

As of 2014, ESA and its industry partners have begun studies on Galileo Second Generation (G2G) satellites, which will be presented to the EC for the late 2020s launch period. One idea is to employ electric propulsion, which would eliminate the need for an upper stage during launch and allow satellites from a single batch to be inserted into more than one orbital plane. The new generation satellites are expected to be available by 2025. and serve to augment the existing network. On 20 January 2021, the European Commission announced that it had awarded a €1.47 billion contract to Thales Alenia Space (TAS) and Airbus Defence and Space for 6 spacecraft by each manufacturer. The signing of the contracts to Thales Alenia Space and Airbus Defence and Space, scheduled on 29 January 2021, was suspended by the European Court of Justice following a protest filed by OHB SE, the losing bidder. The OHB protest at the ECJ's General Court is based on “allegations of theft of trade secrets”, and seeks both a suspension of the contract signatures and the cancellation of the contract award. In May 2021 ESA reported it signed the contracts to design and build the first batch of Galileo Second Generation (G2G) satellites with Thales Alenia Space and Airbus Defence and Space. The 12 G2G satellites will feature electric propulsion, enhanced navigation signals and capabilities, inter-satellite links and reconfigurability in space.

Newspapers and journals around the world speculated that Brazil was acting as a proxy for a naval power which would take possession of the two dreadnoughts soon after completion, as they did not believe that a previously insignificant geopolitical power would contract for such powerful armament. The evidence for a sale seemed strong, as Brazilian attempts to float a multi-million-dollar loan against the value of their coffee crop in 1908 were unsuccessful. With three dreadnoughts planned (including the upcoming ), a Spanish naval journal stated "it was only natural that rumors [would begin] to circulate supporting the argument that Brazil acted as an intermediary for some great power which would acquire them before they terminate their construction." Various British papers speculated that either the Germans, Japanese, or Americans were actually buying the ships, while naval experts in Germany thought the Americans, British, or Japanese were going to take them over. On the other side of the Atlantic, some American papers theorized that the ships would be sold to the United Kingdom, Germany, or Japan. The Brazilian government was forced to deny these spurious allegations several times. The "New York Times" remarked:

While Dykstra's team handled the ships, the V'Ger cloud was developed by Trumbull. Trumbull wanted the cloud to have a specific shape to it—"it couldn't just be a blob of cotton," he said, "it had to have some shape that you could get camera angles on." A special camera support track was built that could pan and focus over a piece of art, with the light strobed to provide depth. While the team planned on compositing multiple passes to provide physical movement to the cloud shots, Trumbull felt that it detracted from the sense of scale, and so small animations were subtly introduced in the final product. The torpedo effects were simulated by shooting a laser through a piece of crystal mounted on a rotating rod after experiments with Tesla coils proved insufficient. The same effect was recolored and used for the Klingons and the "Enterprise"; the aliens' torpedoes glowed red while the "good guys" had blue-colored weaponry. V'Ger's destruction of the ships was created using scanning lasers, with the multiple laser passes composited onto the moving model to create the final effect.

However, recent analysis of the tiny holes in fossil leg bones of dinosaurs provides a gauge for blood flow rate and hence metabolic rate. The holes are called nutrient foramina, and the nutrient artery is the major blood vessel passing through to the interior of the bone, where it branches into tiny vessels of the Haversian canal system. This system is responsible for replacing old bone with new bone, thereby repairing microbreaks that occur naturally during locomotion. Without this repair, microbreaks would build up, leading to stress fractures and ultimately catastrophic bone failure. The size of the nutrient foramen provides an index of blood flow through it, according to the Hagen-Poiseuille equation. The size is also related to the body size of animal, of course, so this effect is removed by analysis of allometry. Blood flow index of the nutrient foramen of the femurs in living mammals increases in direct proportion to the animals' maximum metabolic rates, as measured during maximum sustained locomotion. Mammalian blood flow index is about 10 times greater than in ectothermic reptiles. Ten species of fossil dinosaurs from five taxonomic groups reveal indices even higher than in mammals, when body size is accounted for, indicating that they were highly active, aerobic animals. Thus high blood flow rate, high blood pressure, a four-chambered heart and sustained aerobic metabolism are all consistent with endothermy.

A multitude of complex processes fractionate Zn isotopes in the marine environment. As seen with copper isotopes, the bulk isotopic composition of zinc in the oceans (δZn = +0.5‰) is heavier than that of the riverine input (δZn = +0.3‰), reflecting both equilibrium, biological and other processes that affect Zn isotope ratios in the ocean. In the surface ocean, phytoplankton preferentially uptake Zn, and as a result have average δZn values of ~+0.16‰ (i.e., 0.34‰ lighter than the bulk ocean). This preferential removal of Zn by photosynthetic marine organisms in the photic zone is most prominent in the spring and summer seasons when primary productivity is highest, and the seasonal variability of Zn isotope ratios is reflected in the δZn values of settling materials, which are heavier (e.g., by ~+0.20‰ in the Atlantic Ocean) during spring and summer than during the colder seasons. Additionally, the surface layers of FeMn-nodules are Zn enriched at high-latitudes (average δZn = +1‰), while δZn values of low-latitude samples are smaller and more variable (spanning +0.5 to +1‰). This observation has been interpreted as due to high levels of Zn consumption and preferential uptake of Zn above the seasonal thermocline at high latitudes during warmer seasons, and transfer of this heavy δZn signal to the settling sedimentary Fe-Mn hydroxides.

Gerd Schaller has composed his own completion of the Ninth, closely based on Bruckner's notes. He took into account all available draft materials as far back as the earliest sketches in order to close the remaining gaps in the score as much as possible. He used Bruckner's original manuscript documents, and ran the finale to 736 bars. Additionally, Schaller was able to supplement archival and manuscript material with missing elements in the score by drawing on his experience as a conductor, and applying Bruckner's compositional techniques to the recordings of the complete cycle of all the composer's eleven symphonies. The resulting composition, even the passages without continuous original material, are in a recognizably Brucknerian style. Schaller also creates the broad, dramatically designed reprise of the main theme from Bruckner's earlier sketches. In the coda he quotes the opening theme of the first movement, thereby bridging the beginning of the symphony, a technique of quoting that Bruckner himself used in his symphonies (Symphony No. 3 and Symphony No. 5) and originating back to Beethoven. In the final part of the coda, Schaller renounces the quotations from other works by Bruckner in his newly published revised edition of 2018.

There is an active debate in contemporary philosophy of science as to what should be regarded as observable or empirical in contrast to unobservable or merely theoretical objects. There is general consensus that everyday objects like books or houses are observable since they are accessible via unaided perception, but disagreement starts for objects that are only accessible through aided perception. This includes using telescopes to study distant galaxies, microscopes to study bacteria or using cloud chambers to study positrons. So the question is whether distant galaxies, bacteria or positrons should be regarded as observable or merely theoretical objects. Some even hold that any measurement process of an entity should be considered an observation of this entity. So in this sense, the interior of the sun is observable since neutrinos originating there can be detected. The difficulty with this debate is that there is a continuity of cases going from looking at something with the naked eye, through a window, through a pair of glasses, through a microscope, etc. Because of this continuity, drawing the line between any two adjacent cases seems to be arbitrary. One way to avoid these difficulties is to hold that it is a mistake to identify the empirical with what is observable or sensible. Instead, it has been suggested that empirical evidence can include unobservable entities as long as they are detectable through suitable measurements. A problem with this approach is that it is rather far from the original meaning of "empirical", which contains the reference to experience.

BPF has estrogenic, progesteronic, and anti-androgenic effects. The overarching implications of these hormonal changes for humans are decreases in testosterone secretions, especially in male testes, and increases in the activity of estrogen. The effects are greatest in the fetal testis, which is primed to be more easily affected due to its plasticity and massive period of growth. One study found that BPF had the same effect in lowering testosterone secretions as BPA, increasing over 80% compared to the control in the human fetal testes. It is important to note that this research is done using an in vitro method of fetal testis assay (FeTA), and does not necessarily reflect the mechanisms BPF would undergo if ingested by humans. For example, the ability for BPF to activate oestrogen in the receptors is lower than that of BPA, (one study suggests 5- to 10-fold lower) and the actions of these bisphenols are likely not directly through these receptors, but rather more indirect. As such, most research done on this topic has been using human cell line cultures, rather than studies on mammalian in vivo exposure. Several other reviews have all shown that BPF demonstrates similar endocrine and physiological disruptions as BPA, both in vitro and in vivo primary organoid cell cultures, especially demonstrating its estrogenic and anti-androgenic actions.

Jisc took a decision to establish the Digital Curation Centre some time in 2002, having funded a number of projects in the field of digital preservation. Jisc's then digital preservation focus, Neil Beagrie, recognised that a number of the more compelling challenges required more than simple preservation of materials. The term digital curation was coined to refer to more active long-term management of digital material. The original call for bids to run the center was withdrawn in July 2003, allowing the UK's e-science programme to add funding for a 4-year research programme to complement the work on education and advocacy funded by Jisc. The revised call from July 2003 required bids by 2003-09-18 with an intention to establish the DCC early in 2004. The range of expertise required meant that the funders expected to see collaborative, multi-centre bids. A number were shortlisted with the winning bid chosen on 2003-11-26. Led by the University of Edinburgh (involving its School of Informatics, the National e-Science Centre (NeSC), the EDINA national data centre and the AHRC Centre for the Studies in Intellectual Property and Technology Law) the winning consortium also included HATII at the University of Glasgow, UKOLN at the University of Bath, and the Science and Technology Facilities Council (STFC).

The commission determined that the cause of the accident was hot gas blowing past the O-rings in the field joint on the right SRB, and found no other potential causes for the disaster. It attributed the accident to a faulty design of the field joint that was unacceptably sensitive to changes in temperature, dynamic loading, and the character of its materials. The report was critical of NASA and Morton Thiokol, and emphasized that both organizations had overlooked evidence that indicated the potential danger with the SRB field joints. It noted that NASA accepted the risk of O-ring erosion without evaluating how it could potentially affect the safety of a mission. The commission concluded that the safety culture and management structure at NASA were insufficient to properly report, analyze, and prevent flight issues. It stated that the pressure to increase the rate of flights negatively affected the amount of training, quality control, and repair work that was available for each mission.

Once on the ground, the aircraft had to be retrieved by a "Scheuch-Schlepper", a converted small agricultural vehicle, originally based on the concept of the two-wheel tractor, carrying a detachable third swiveling wheel at the extreme rear of its design for stability in normal use—this swiveling third wheel was replaced with a pivoting, special retrieval trailer that rolled on a pair of short, triple-wheeled continuous track setups (one per side) for military service wherever the "Komet" was based. This retrieval trailer usually possessed twin trailing lifting arms, that lifted the stationary aircraft off the ground from under each wing whenever it was not already on its twin-wheel dolly main gear, as when the aircraft had landed on its ventral skid and tailwheel after a mission. Another form of trailer, known also to have been trialled with the later B-series examples, was tried during the "Komet"s test phase, which used a pair of sausage-shaped air bags in place of the lifting arms and could also be towed by the "Scheuch-Schlepper" tractor, inflating the air bags to lift the aircraft. The three-wheeled "Scheuch-Schlepper" tractor used for the task was originally meant for farm use, but such a vehicle with a specialized trailer—which could also lift the Me 163's airframe completely clear of the ground to effect the recovery as a normal part of the Me 163's intended use—was required as the "Komet" was unpowered after exhausting its rocket propellants, and lacked main wheels after landing, from the jettisoning of its "dolly" main gear at takeoff.

Research with animal models that are irradiated with HZE nuclei has shown that important changes to the CNS occur with the dose levels that are of concern to NASA. However, the significance of these results on the morbidity to astronauts has not been elucidated. One model of late tissue effects suggests that significant effects will occur at lower doses, but with increased latency. It is to be noted that the studies that have been conducted to date have been carried out with relatively small numbers of animals (<10 per dose group); therefore, testing of dose threshold effects at lower doses (< 0.5 Gy) has not been carried out sufficiently at this time. As the problem of extrapolating space radiation effects in animals to humans will be a challenge for space radiation research, such research could become limited by the population size that is used in animal studies. Furthermore, the role of dose protraction has not been studied to date. An approach to extrapolate existing observations to possible cognitive changes, performance degradation, or late CNS effects in astronauts has not been discovered. New approaches in systems biology offer an exciting tool to tackle this challenge. Recently, eight gaps were identified for projecting CNS risks. Research on new approaches to risk assessment may be needed to provide the necessary data and knowledge to develop risk projection models of the CNS from space radiation.

In the United States, in 1857, the Flobert cartridge inspired the .22 Short (another rimfire), specially conceived for the first American revolver using rimfire cartridges, the Smith & Wesson Model 1. A year before, in 1856, the LeMat revolver was the first American (French-designed) breech-loading firearm, but it used pinfire cartridges, not rimfire. Formerly, an employee of the Colt's Patent Firearms Manufacturing Company, Rollin White, had been the first in America to conceive the idea of having the revolver cylinder bored through to accept metallic cartridges ( 1852), with the first in the world to use bored-through cylinders probably having been Lefaucheux in 1845, who invented a pepperbox-revolver loaded from the rear using bored-through cylinders. Another possible claimant for the bored-through cylinder is a Frenchman by the name of Perrin, who allegedly produced in 1839 a pepperbox revolver with a bored-through cylinder to order. Other possible claimants include Devisme of France in 1834 or 1842 who claimed to have produced a breech-loading revolver in that period though his claim was later judged as lacking in evidence by French courts and Hertog & Devos and Malherbe & Rissack of Belgium who both filed patents for breech-loading revolvers in 1853. However, Samuel Colt refused this innovation. White left Colt, went to Smith & Wesson to rent a license for his patent, and this is how the S&W Model 1 saw the light of day in 1857. The patent didn't definitely expire until 1870, allowing Smith & Wesson competitors to design and commercialize their own revolving breech-loaders using metallic cartridges. Famous models of that time are the Colts Open Top (1871–1872) and Single Action Army "Peacemaker" (1873). But in rifles, the lever-action mechanism patents were not obstructed by Rollin White's patent infringement because White only held a patent concerning drilled cylinders and revolving mechanisms. Thus, larger caliber rimfire cartridges were soon introduced after 1857, when the Smith & Wesson .22 Short ammunition was introduced for the first time. Some of these rifle cartridges were used in the American Civil War, including the .44 Henry and 56-56 Spencer (both in 1860). However, the large rimfire cartridges were soon replaced by centerfire cartridges, which could safely handle higher pressures.

Over the years, desktop computer hardware capabilities have improved by orders of magnitude, and so for most programmers, tight hardware restrictions are no longer a common issue. Nevertheless, demosceners continue to study and experiment with creating impressive effects on limited hardware. Since handheld consoles and cellular phones have comparable processing power or capabilities to the desktop platforms of old (such as low resolution screens which require pixel-art, or very limited storage and memory for music replay), many demosceners have been able to apply their niche skills to develop games for these platforms, and earn a living doing so. One particular example is Angry Birds, whose lead designer Jaakko Iisalo was an active and well-known demoscener in the 90s. Unity Technologies is another notable example, its technical leads on iPhone, Android and Nintendo Switch platforms Renaldas Zioma and Erik Hemming are authors of Suicide Barbie demo for Playstation Portable console released in 2007.

Building on this picture, as well as a 2000 article on time-correlated soliton tunneling, a more recent quantum model proposes Josephson-like coupling (see Josephson effect) between complex order parameters associated with nucleated droplets of charged soliton dislocations on many parallel chains. Following Richard Feynman in The Feynman Lectures on Physics, Vol. III, Ch. 21, their time-evolution is described using the Schrödinger equation as an emergent classical equation. The narrow-band noise and related phenomena result from the periodic buildup of electrostatic charging energy and thus do not depend on the detailed shape of the washboard pinning potential. Both a soliton pair-creation threshold and a higher classical depinning field emerge from the model, which views the CDW as a sticky quantum fluid or deformable quantum solid with dislocations, a concept discussed by Philip Warren Anderson.

The GP Forward View, published by NHS England in 2016 promised £2.4 billion (14%) real-terms increase in the budget for general practice. Jeremy Hunt pledged to increase the number of doctors working in general practice by 5,000. There are 3,250 trainee places available in 2017. The GP Career Plus scheme is intended to retain GPs aged over 55 in the profession by providing flexible roles such as providing cover, carrying out specific work such as managing long-term conditions, or doing home visits. In July Simon Stevens announced a programme designed to recruit around 2,000 GPs from the EU and possibly New Zealand and Australia. According to NHS Improvement a 1% deterioration in access to general practice can produce a 10% deterioration in emergency department figures.

During repairs following the Qantas Flight 32 engine failure incident, cracks were discovered in wing fittings. As a result, the European Aviation Safety Agency issued an Airworthiness Directive in January 2012 which affected 20 A380 aircraft that had accumulated over 1,300 flights. A380s with under 1,800 flight hours were to be inspected within 6 weeks or 84 flights; aircraft with over 1,800 flight hours were to be examined within four days or 14 flights. Fittings found to be cracked were replaced. On 8 February 2012, the checks were extended to cover all 68 A380 aircraft in operation. The problem is considered to be minor and is not expected to affect operations. EADS acknowledged that the cost of repairs would be over $130 million, to be borne by Airbus. The company said the problem was traced to stress and material used for the fittings. Additionally, major airlines are seeking compensation from Airbus for revenue lost as a result of the cracks and subsequent grounding of fleets. Airbus has switched to a different type of aluminium alloy so aircraft delivered from 2014 onwards should not have this problem.

A simple container (U-tube) is filled with a solid or catalyst. This sample vessel is positioned in a furnace with temperature control equipment. A thermocouple is placed in the solid for temperature measurement. The air originally present in the container is flushed out with an inert gas (nitrogen, argon). Flow controllers are used to add hydrogen (for example, 10% hydrogen in nitrogen). The composition of the gaseous mixture is measured at the exit of the sample container with appropriate detectors (thermal conductivity detector, mass spectrometer). Now, the sample in the oven is heated up on predefined values. Heating rates are usually between 1 K/min and 20 K/min. If a reduction takes place at a certain temperature, hydrogen is consumed, which is recorded by the detector. In practice the production of water is a more accurate way of measuring the reduction. This is due to the potential for varying hydrogen concentrations at the inlet, so the decrease in this number may not be precise, however as the starting concentration of water will be zero, any increase can be measured more accurately.

The novel then goes back in time to 1898, when the Marie Curie and her husband discover radioactivity. The story presents a brief timeline that continues up into the 1930s, when James Chadwick discovers neutrons and the discovery of nuclear fission. The novel takes a shift, and begins to discuss the political environment. Leo Szilard becomes troubled as he sees the dangers that these nuclear weapons could produce, and travels with Eugene Wigner to talk with Albert Einstein about the possibility of Nazi scientists creating a bomb. News soon reaches the United States president, who authorizes the precursor to the Manhattan Project. After the bombing of Pearl Harbor, the United States founds covertly Los Alamos National Laboratory and other cities to create nuclear weapons. The scientists and their families are sworn to secrecy. Soon, the scientists at Los Alamos discover how to create a nuclear chain reaction, leading to the development of the first atomic weapons: Little Boy and Fat Man.

The sound design team began working on the game early in development, in order to achieve the best results; they immediately realized that it would be challenging. Early in development, Druckmann told the sound team to "make it subtle", and underplay ideas. Audio lead Phillip Kovats was excited to completely create all sounds; no sounds were carried across from previous games. The team looked at ways to create sounds from a naturalistic point-of-view, and how to introduce minimalism into a game. By doing so, they found that it added feelings of tension, loss and hope, and that the game appeared to be a typical "action game" without the minimalism approach. They used a high dynamic range, allowing them the opportunity to inform players on tactical information, and locations to explore. The game's sound design was created to reflect a more "grounded" and subtle mood than "Uncharted", particularly focusing on the lack of sound. Taking inspiration from "No Country for Old Men", the team attempted to "do more with less"; Kovats said that the team was trying to tell a story by "going for a reductive quality". Straley stated that the audio is vital to some scenes in the game; "It's more about the psychology of what's happening on the audioscape than what you're seeing," he stated. He felt that this decision allowed a more impactful and meaningful effect with sound occurred. The sound team also attempted to portray the game's dark themes through sound. The team felt that it was important to let sounds play for as long as possible in the game, drawing tension. The team used a propagation technique to help players determine the exact locations of enemies, using this as a tactical advantage. This system, created by the team at Naughty Dog, is processed at random in the game engine. For the game's audio, the engine throws out 1500–2500 ray casts per frame; though most games avoid this, the game's engine allowed it to work. The team spent a lot of time recording sounds for the game, namely doors, and rusty metal. Sound designer Neil Uchitel traveled to Rio de Janeiro, discovering locations to record sounds; he recorded chickens, which were used in the game as the sounds of rats. The team continued to add and change the game's sounds until the end of development.

Hotchkiss machine guns firing 7 mm Mauser ammunition equipped both sides (government and rebels) during the Mexican Revolution (1911–1920). Furthermore, the Mle 1914 Hotchkiss in 8 mm Lebel was mounted in all French tanks and armored cars of World War I. Some examples of tanks that used the Mle 1914 Hotchkiss include the Schneider CA1, Saint-Chamond, Renault FT and Char 2C. Conversely, British tanks and armored cars were fitted with the distinctly different Mle 1909 light Hotchkiss (a.k.a. the "Benét–Mercié"). A recently published series of modern firing tests with vintage machine guns summarizes the Mle 1914 Hotchkiss as being: ""A heavy and rock-steady combination of gun and tripod, the world's first efficient air cooled machine gun is admirably reliable and accurate"" (Robert Bruce, 1997). These qualities provided the French military with an excuse to keep the Hotchkiss in active service far beyond its point of obsolescence and into World War II. The last recorded uses of the Hotchkiss by the French Army were in Indochina and Algeria, after World War II, to defend outposts in static positions. It is said to have been used by Communist forces in Korean and Vietnam Wars.

These principles and the ongoing evolution of PAR have had a lasting legacy in fields ranging from problem solving in the workplace to community development and sustainable livelihoods, education, public health, feminist research, civic engagement and criminal justice. It is important to note that these contributions are subject to many tensions and debates on key issues such as the role of "clinical psychology", "critical social thinking" and the pragmatic concerns of "organizational learning" in PAR theory and practice. Labels used to define each approach (PAR, critical PAR, action research, psychosociology, sociotechnical analysis, etc.) reflect these tensions and point to major differences that may outweigh the similarities. While a common denominator, the combination of participation, action and research reflects the fragile unity of traditions whose diverse ideological and organizational contexts kept them separate and largely ignorant of one another for several decades.

Two years later, the school moved to its current location on the grounds of the recently closed Tampa Bay Hotel, which Henry B. Plant had built in 1891 directly across the Hillsborough River from downtown Tampa. The sprawling resort initially featured a quarter-mile long main building with over 500 guest rooms along with several adjoining buildings and amenities ranging from an indoor pool to a casino to a race track, all spread across six acres of land. After some initial success, however, it struggled to consistently attract enough patrons to make a profit, The city of Tampa purchased the hotel after Plant's death and kept it open by contracting out daily operations to private companies, but it finally shut down in 1931 due to a significant downturn in tourism with the coming of the Great Depression. In 1933, the city agreed to allow Tampa Junior College to move its operations to the former hotel grounds rather than let the iconic buildings remain empty.

The orbit was oval, and narrow towards the bottom. The jugal bone had two upwards pointing processes, the first of which formed part of the lower margin of the antorbital fenestra, and part of the lower margin of the orbit. A projection from the quadrate bone into the lateral temporal fenestra (opening behind the eye) gave this a reniform (kidney-shaped) outline. The foramen magnum (the large opening at the back of the braincase) was about half the breadth of the occipital condyle, which was itself cordiform (heart-shaped), and had a short neck and a groove on the side. The mandible was slender and delicate at the front, but the articular region (where it connected with the skull) was massive, and the mandible was deep around the mandibular fenestra (an opening on its side). The mandibular fenestra was small in "Dilophosaurus", compared to that of coelophysoids, and reduced from front to back, uniquely for this genus. The dentary bone (the front part of the mandible where most of the teeth there were attached) had an up-curved rather than pointed chin. The chin had a large foramen at the tip, and a row of small foramina ran in rough parallel with the upper edge of the dentary. On the inner side, the mandibular symphysis (where the two halves of the lower jaw connected) was flat and smooth, and showed no sign of being fused with its opposite half. A Meckelian foramen ran along the outer side of the dentary. The side surface of the had a unique pyramidal process in front of the articulation with the quadrate, and this horizontal ridge formed a shelf. The retroarticular process of the mandible (a backwards projection) was long.

The Russian Federation contains one sixth of the world’s land mass and around half of the country’s territory is what could be considered continuous wilderness, with large expanses of boreal forests providing relatively untouched habitat for an extremely wide diversity of species. The temperate rainforests are located at the intersection of the Pacific tectonic plate and the Eurasian continent’s plate in far southeastern Russia, forming an area with a unique set of characteristics seen no where else in the world. During the last glacial maximum, the area was not glaciated, allowing for the development of a complex ecosystem containing species with origins in Siberia’s boreal forest and Manchuria’s subtropical forests. Historically these forests ranged from the southeastern Pacific coast of Russia, North Korea, and into northern China, however large amounts of human development (in China especially) has limited the forest to its current range in the Russian Far East. In 2001, UNESCO recognized a 1.5 million hectare area of forest in the central part of the Sikhote-Alin mountains as a World Heritage Site in Russia, citing the area as one of the most unique and valuable areas of intact forest in the world

The ability of developing countries to build their natural capital account capacities is being improved significantly through the Wealth Accounting and Ecosystem Partnership Services (WAVES), by encouraging the development of relevant measurement frameworks. WAVES is global partnership that was inaugurated in October 2010 by World Bank President Robert Zoellick at the Convention on Biological Diversity COP-10 meeting in Japan. It aims to promote sustainable development by encouraging the inclusion of natural capital measurements in national accounts. Several projects have been initiated in developing countries such as Botswana, Colombia and Madagascar with a view to improving their capacity to implement the SEEA, in collaboration with UNEP, the UNDP, the United Nations Statistical Commission, and the financial support of NGOs and the governments of Australia, Canada, France, Japan, Norway and the United States.

At Einstein, an NIH funded project was undertaken to use SMBG data to devise an algorithm that would determine how much insulin was required to alter blood glucose levels in type 1 diabetes. It quickly became clear that 96 patients testing 4 times a day would produce an enormous amount of data and that these data would somehow have to be copied and recorded by hand on spreadsheets. By happenstance, working with systems analysts, a memory chip was added to the reflectance meter and software was developed to capture the patient data. Using these modified meters in the study patients it was discovered that the data recorded in their logbooks were subject to three errors: over-reporting, under-reporting and imprecision. This resulted in 75% of the research patients providing erroneous glucose data thus thwarting efforts to find an algorithm. Following publication of these results, other investigators confirmed the findings suggesting that patient self-reported data were subject to fabrication and unless independently verified might prove dangerous in terms of clinical decision-making.

Constructed between 1987 and 1991, Biosphere 2 was originally meant to demonstrate the viability of closed ecological systems to support and maintain human life in outer space as a substitute for Earth's biosphere. It was designed to explore the web of interactions within life systems in a structure with different areas based on various biological biomes. In addition to the several biomes and living quarters for people, there was an agricultural area and work space to study the interactions between humans, farming, technology and the rest of nature as a new kind of laboratory for the study of the global ecology. Its mission was a two-year closure experiment with a crew of eight humans ("biospherians"). Long-term it was seen as a precursor to gaining knowledge about the use of closed biospheres in space colonization. As an experimental ecological facility it allowed the study and manipulation of a mini biospheric system without harming Earth's biosphere.

After the Second World War broke out in Europe, he was interned in the Isle of Man, and later in Canada. After he returned to Britain in 1941, he became an assistant to Rudolf Peierls, working on "Tube Alloys"—the British atomic bomb project. He began passing information on the project to the Soviet Union through Ursula Kuczynski, codenamed "Sonya", a German communist and a major in Soviet military intelligence who had worked with Richard Sorge's spy ring in the Far East. In 1943, Fuchs and Peierls went to Columbia University, in New York City, to work on the Manhattan Project. In August 1944, Fuchs joined the Theoretical Physics Division at the Los Alamos Laboratory, working under Hans Bethe. His chief area of expertise was the problem of implosion, necessary for the development of the plutonium bomb. After the war, he returned to the UK and worked at the Atomic Energy Research Establishment at Harwell as head of the Theoretical Physics Division.

At least 94 disease-causing mutations in this gene have been discovered. Mutations in this gene are associated with two disorders: autosomal recessive GTP cyclohydrolase I deficiency and autosomal dominant GTP cyclohydrolase I deficiency. These may present with malignant phenylketonuria (PKU) and hyperphenylalaninemia (HPA) and lead to a lack of certain neurotransmitters (dopamine, norepinephrine, epinephrine and serotonin). The dominant form, with mutation in only one of the two alleles for GTP cyclohydrolase I, causes dopamine-responsive dystonia, characterized by childhood-onset dystonia. Patients with the recessive form have mutations in both alleles for GTP cyclohydrolase I. Patients present with developmental delays and neurological dysfunction with trunk hypotonia, hypertonia of the extremities, abnormal movements, tremors, convulsions, and sometimes autonomic dysfunction. Response to treatment is variable and the long-term and functional outcome is unknown. To provide a basis for improving the understanding of the epidemiology, genotype/phenotype correlation and outcome of these diseases their impact on the quality of life of patients, and for evaluating diagnostic and therapeutic strategies a patient registry was established by the noncommercial International Working Group on Neurotransmitter Related Disorders (iNTD).

The An-124 is powered by four Lotarev D-18 turbofan engines, each capable of generating up to 238–250 kN of thrust. To reduce the landing distance required, thrust reversers are present. Pilots have stated that the airlifter is relatively light on the controls and is easy to handle for an aircraft of its size. A pair of TA18-200-124 auxiliary power units (APUs) are accommodated within the main landing gear fairings. As a consequence of the heat and blast effects produced by these APUs, some airports require pavement protection to be deployed. The landing gear of the An-124 is outfitted with an oleo strut suspension system for its 24 wheels. This suspension has been calibrated to allow for landing on rough terrain and is able to kneel, which allows for easier loading and unloading via the front cargo door. Other features intended to ease loading including an onboard overhead crane in the cargo deck, capable of lifting up to 30 tonnes, while items up to 120 tonnes can be winched on board. Two separate radar units are typically present, one is intended for ground mapping and navigation purposes, while the other is for weather.

In 1951, Carl Wiley led a team at Goodyear Aircraft Corporation (later Goodyear Aerospace) in developing a technique for greatly expanding and improving the resolution of radar-generated images. Called synthetic aperture radar (SAR), an ordinary-sized antenna fixed to the side of an aircraft is used with highly complex signal processing to give an image that would otherwise require a much larger, scanning antenna; thus, the name synthetic aperture. As each pulse is emitted, it is radiated over a lateral band onto the terrain. The return is spread in time, due to reflections from features at different distances. Motion of the vehicle along the flight path gives the horizontal increments. The amplitude and phase of returns are combined by the signal processor using Fourier transform techniques in forming the image. The overall technique is closely akin to optical holography.

The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin forms a complex with and functions as a regulatory subunit of CDK2, whose activity is required for cell cycle G1/S transition. This protein accumulates at the G1-S phase boundary and is degraded as cells progress through S phase. Overexpression of this gene has been observed in many tumors, which results in chromosome instability, and thus may contribute to tumorigenesis. This protein was found to associate with, and be involved in, the phosphorylation of NPAT protein (nuclear protein mapped to the ATM locus), which participates in cell-cycle regulated histone gene expression and plays a critical role in promoting cell-cycle progression in the absence of pRB. Two alternatively spliced transcript variants of this gene, which encode distinct isoforms, have been described. Two additional splice variants were reported but detailed nucleotide sequence information is not yet available.

In 1915, the chair of the Ontario chapter of the Red Cross, Colonel Albert Gooderham, was tapped by the university to help address the issue of space. Gooderham, the grandson of William Gooderham and heir to a portion of the Gooderham & Worts Distillery fortune purchased and donated a 58-acre farm several miles north of Toronto to be used to house laboratory animals. Gooderham requested the antitoxin laboratories and farm facility be renamed the Connaught Antitoxin Laboratories and University Farm, in honour of the Governor General of Canada at the time, Prince Arthur, Duke of Connaught and Strathearn. The chair of the Rockefeller Foundation, Simon Flexner, attended the opening ceremony in 1917, giving the evening address in Convocation Hall. It has been speculated that Flexner's impression of the importance of FitzGerald and his work may have contributed to Rockefeller's subsequent support of the School. Gooderham later provided additional monies to construct laboratory facilities at the farm. Although physically separated from the university, the farm and co-located laboratory remained controlled by the University with the intent that the Connaught facility would support its commercial operation and research activities through cost-recovery. Ultimately in 1923, the Antitoxin Laboratory in the Department of Hygiene also changed its name to Connaught Laboratories.

In 1801 Gauss introduced the integers mod p, where p is a prime number. Galois extended this in 1830 to finite fields with formula_13 elements. In 1871 Richard Dedekind introduced, for a set of real or complex numbers that is closed under the four arithmetic operations, the German word "Körper", which means "body" or "corpus" (to suggest an organically closed entity). The English term "field" was introduced by Moore in 1893. In 1881 Leopold Kronecker defined what he called a "domain of rationality", which is a field of rational fractions in modern terms. The first clear definition of an abstract field was due to Heinrich Martin Weber in 1893. It was missing the associative law for multiplication, but covered finite fields and the fields of algebraic number theory and algebraic geometry. In 1910 Steinitz synthesized the knowledge of abstract field theory accumulated so far. He axiomatically defined fields with the modern definition, classified them by their characteristic, and proved many theorems commonly seen today.

The LA 2 (ЛА-2) is a Carbine. The sample was designed by Izhevsk Machine-Building Plant A. I. Nesterov in 1961 under the influence of plant competition for the AKM. The sample frame limited progress in its rearmost position of the cutting insert receiver. This allowed the elasticity of its walls to reduce the impact of hitting the moving parts in an extreme position on the tip-off weapon. Automatic mode shows improved shooting accuracy. Location of the return spring on the left side of the bolt allowed its height to be reduced along with the height of the arms in general. Shoe flies combine with the gas chamber, with a diopter sight fully posted on the cover of the receiver. A cleaning gas vent at the top of the gas chamber in the firing position is covered by a crane. Weight is reduced to .

The greatest challenge is the sheer size of the radio search needed to look for signals (effectively spanning the entire observable universe), the limited amount of resources committed to SETI, and the sensitivity of modern instruments. SETI estimates, for instance, that with a radio telescope as sensitive as the Arecibo Observatory, Earth's television and radio broadcasts would only be detectable at distances up to 0.3 light-years, less than 1/10 the distance to the nearest star. A signal is much easier to detect if it consists of a deliberate, powerful transmission directed at Earth. Such signals could be detected at ranges of hundreds to tens of thousands of light-years distance. However, this means that detectors must be listening to an appropriate range of frequencies, and be in that region of space to which the beam is being sent. Many SETI searches assume that extraterrestrial civilizations will be broadcasting a deliberate signal, like the Arecibo message, in order to be found.

In western countries, women are around two to three times more likely to be diagnosed with IBS and four to five times more likely to seek specialty care for it than men. However, women in East Asian countries are not more likely than men to have irritable bowel syndrome, and there are conflicting reports about the female predominance of the disease in Africa and other parts of Asia. People diagnosed with IBS are usually younger than 45 years old. Studies of females with IBS show symptom severity often fluctuates with the menstrual cycle, suggesting hormonal differences may play a role. Endorsement of gender-related traits has been associated with quality of life and psychological adjustment in IBS. The increase in gastrointestinal symptoms during menses or early menopause may be related to declining or low estrogen and progesterone, suggesting that estrogen withdrawal may play a role in IBS. Gender differences in healthcare-seeking may also play a role. Gender differences in trait anxiety may contribute to lower pain thresholds in women, putting them at greater risk for a number of chronic pain disorders. Finally, sexual trauma is a major risk factor for IBS, as are other forms of abuse. Because women are at higher risk of sexual abuse than men, sex-related risk of abuse may contribute to the higher rate of IBS in women.

Microspheres have been used to produce focal regions, known as photonic nanojets and whose sizes are large enough to support internal resonances, but at the same time small enough, so that geometrical optics cannot be applied for studying their properties. Previous research has demonstrated experimentally and with simulations the use of microspheres in order to increase the signal intensity obtained in different experiments. A confirmation of the photonic jet in the microwave scale, observing the backscattering enhancement that occurred when metallic particles were introduced in the focus area. A measurable enhancement of the backscattered light in the visible range was obtained when a gold nanoparticle was placed inside the photonic nanojet region produced by a dielectric microsphere with a 4.4 μm diameter. A use of nanojets produced by transparent microspheres in order to excite optical active materials, under upconversion processes with different numbers of excitation photons, has been analyzed as well.

For the past century, the measurement of pain in rodent biomedical research was considered complicated and imprecise, and many researchers suggested there is a mismatch between human clinical pain symptoms and established procedures in rodents. Based on the human Neonatal Facial Coding Scale, which is itself based on the Facial Action Coding System, Mogil and colleagues developed the Mouse Grimace Scale and the Rat Grimace Scale. The original findings were highly cited, widely covered in the scientific press, and Mogil was awarded the Bennet Cohen Award from the International Council for Laboratory Animal Science and the SGV Award from the Swiss Laboratory Animal Science Association for the finding. Grimace scales are now routinely used in institutional veterinary settings for the determination of post-operative pain in animals, and have been developed for 10 species: mice, rats, rabbits, cats, horses, cows, pigs, sheep, ferret, and seal.

The development and application of computational algorithms for ancestral reconstruction continues to be an active area of research across disciplines. For example, the reconstruction of sequence insertions and deletions (indels) has lagged behind the more straightforward application of substitution models. Bouchard-Côté and Jordan recently described a new model (the Poisson Indel Process) which represents an important advance on the archetypal Thorne-Kishino-Felsenstein model of indel evolution. In addition, the field is being driven forward by rapid advances in the area of next-generation sequencing technology, where sequences are generated from millions of nucleic acid templates by extensive parallelization of sequencing reactions in a custom apparatus. These advances have made it possible to generate a "deep" snapshot of the genetic composition of a rapidly evolving population, such as RNA viruses or tumour cells, in a relatively short amount of time. At the same time, the massive amount of data and platform-specific sequencing error profiles has created new bioinformatic challenges for processing these data for ancestral sequence reconstruction.

Paul Wild became one of the young radar officers who ensured the Royal Navy used its new technology to maximum effect. In July 1943, commissioned as a Probationary Temporary Acting Sub-lieutenant (Special Branch, Royal Navy Volunteer Reserve), he started an intensive, six-month radar officer training course at the Royal Navy base, Portsmouth. His seagoing appointment for the following two and a half years, with 60 subordinates and 24 radar sets, was the battleship , which eventually became flagship of the British Pacific Fleet. The ship took part in the Okinawa campaign, followed by the assault on the Japanese mainland. In both campaigns the fleet was frequently attacked by Japanese suicide bombers, but because they tended to concentrate on aircraft carriers, his ship was not hit. The battleship entered Tokyo Bay just after the surrender of Japan and he was present when the peace treaty was signed.

Maleev originally classified "Therizinosaurus" as a giant marine turtle and the genus was assigned by him to a separate family, Therizinosauridae given how enigmatic the specimen was. The fossils remained with uncertainty among the scientific community; however, in 1970 Rozhdestvensky was one of the first paleontologists to suggest that "Therizinosaurus" was actually a theropod dinosaur instead of a turtle. He also suggested that the supposed ribs of the holotype were likely from a different dinosaur, possibly a sauropodomorph. In 1976 Barsbold concluded that "Therizinosaurus" was a theropod because MPC-D 100/15 matched numerous theropodan characters, and that Therizinosauridae and Deinocheiridae were probably synonyms. With the discovery and description of "Segnosaurus", in 1979 Perle named a new family of dinosaurs, the "Segnosauridae". He tentatively placed the family within Theropoda given the similarities of the mandible and dentition to other members. A year later, the new genus "Erlikosaurus" was named by Barsbold and Perle in 1980. They named a new infraorder called the Segnosauria, composed of "Erlikosaurus" and "Segnosaurus". They also noted that while aberrant and having ornithischian-like pelves, segnosaurs featured similar traits to other theropods. With the discovery of the referred hindlimb to "Therizinosaurus" in 1982 by Perle, he concluded that "Segnosaurus" was very similar to the latter based on the morphology and they possibly belonged to a single, if not the same, group. In 1983, Barsbold named a new genus of segnosaur, "Enigmosaurus". He analyzed the pelvis of the new genus and pointed out that segnosaurids were so different from other theropods that they could be outside the group or represent a different lineage of theropod dinosaurs. Later on the same year, he intensified the exclusion of segnosaurs from being theropods by noting that their pelves resembled those of sauropod dinosaurs.

During the interwar period between the First and Second World War, the need for a faster and more efficient method of constructing artillery firing tables prompted BRL to consider the potential applications of digital computation. In 1935, before the Research Division became BRL, the Technical Staff acquired a copy of the Bush differential analyzer, which could compute a 60-second trajectory in about 15 minutes compared to about 20 hours performed by a person with a desk calculator. However, even the differential analyzer was not enough to keep up with the needs of the U.S. Army. By 1941, the production of firing tables was so far behind that BRL rushed to find any means of expediting the ballistic computation process. To ease the burden of work, the lab trained almost 100 female graduates from colleges all over the Northeast to calculate ballistic firing tables. When the Women's Army Corps was formed, those assigned to ballistic computation were trained in Philadelphia and deployed to Aberdeen Proving Ground. During this time, Colonel Paul Gillon of the OCO had his attention on the Moore School of Electrical Engineering at the University of Pennsylvania. Gillon, who oversaw the ballistic computations needed for the firing and bombing tables, knew that an upgraded version of the Bush differential analyzer existed at the Moore School.

In 1969 he transferred to the newly created Department of Communications in Ottawa and from 1970 to 1975 was Project manager for the communications technology satellite Hermes. In 1976 he carried out a study and produced the DOC report which led in 1978 to the signing of an Agreement for cooperation between Canada and the European Space Agency (ESA). In 1976 he was posted to the ESA HQ in Paris where he worked for a year in the Department of Future Programs and Plans. In 1977 he returned to Canada as Director General of Space Programs and subsequently Director General of Space and Information Technology Programs in the Department of Communications. His responsibilities included space industry support, planning and management of the Canadian mobile satellite program and Canada's participation in European communications satellite programs as well as the concluding phases of the Federal governments Office Communications and Videotex and Teletext programs. From 1986 to 1987 he moved to the Ministry of State for Science and Technology to assist in the drafting of a Cabinet submission for the establishment of a Canadian Space Agency and a long term space plan. The latter resulted in Canada's participation in the US Space Station Program, and approval to proceed with the MSAT and Radarsat programs. From 1987 to 1990 he was a Visiting Professor in the Electrical Engineering Department, the University of Auckland, New Zealand. From 1990 to 1992 he was Chief Scientist at Spar Aerospace Ltd at Sainte-Anne-de-Bellevue, Quebec, Quebec.

A second review of the first volume appeared in "Nature". This was more critical in its stance with the reviewer noting that although the overall classification scheme was based on Sharpe's Handlist, at several points it had been altered "according to the author's personal ideas" rather than following the general ornithological consensus of the time. Also faulted was the lack of a clear rational to the order in which certain families such as the Rollers, Kingfishers, Bee-eaters appeared. This the reviewer believed was "a convenient and easy method to adopt, but surely not very scientific." The names given to some of the birds was also called into question. On the other hand, the reviewer praised the "excellent geographical preamble" declaring that "there can be very few people who will not be able to learn a great deal from this" and observed that the book as a whole "is well worthy of the great reputation the author already enjoys." And the review concludes by congratulating Robinson "on having been completely successful in bringing out a work which is very badly needed and one which will undoubtedly, for many years to come, be the standard work of the birds of the Malay region."

Strong evidence in rats supports the conclusion that neonatal estrogen exposure plays a role in the development of prostate cancer. Using a human fetal prostate xenograft model, researchers studied the effects of early exposure to estrogen with and without secondary estrogen and testosterone treatment. A xenograft model is a graft of tissue transplanted between organisms of different species. In this case, human tissue was transplanted into rats; therefore, there was no need to extrapolate from rodents to humans. Histopathological lesions, proliferation, and serum hormone levels were measured at various time-points after xenografting. At day 200, the xenograft that had been exposed to two treatments of estrogen showed the most severe changes. Additionally, researchers looked at key genes involved in prostatic glandular and stromal growth, cell-cycle progression, apoptosis, hormone receptors, and tumor suppressors using a custom PCR array. Analysis of DNA methylation showed methylation differences in CpG sites of the stromal compartment after estrogen treatment. These variations in methylation are likely a contributing cause to the changes in the cellular events in the KEGG prostate cancer pathway that inhibit apoptosis and increase cell cycle progression that contribute to the development of cancer.

In the "Spider-Man Noir" series as part of the "Marvel Noir" universe, his name first appears in the "Daily Bugle" newspaper as one of the biologists undertaking an oceanic voyage on a research ship named the "Atlantis". He appears in person in issue #1 of the sequel series, "Eyes Without a Mask". Here, he is a doctor working in a facility on Ellis Island. His legs are crippled and withered, and he travels in a wheelchair with six long metal claw-like tentacles sticking out. He is officially conducting experiments on primates to study their brains in connection with evolution and, in the end, it is shown he is secretly taking in kidnapped African Americans for his own, more secret experiments. He is later revealed to in fact be working with the Nazis and their American proxies, the "Friends of New Germany", with the plot of making all minorities into mindless slaves. However, his experiments are uncovered by Spider-Man, and although he is allowed to leave the country due to his past service to America, he is subsequently rejected by the Nazis, as they believe his crippled body reflects a crippled mind that could produce nothing of value for them.

The head clinician at Eberswalde, although initially very annoyed, recognized Werner's discovery when shown the X-rays; he allowed Forssmann to carry out another catheterization on a terminally ill woman whose condition improved after being given drugs in this way. An unpaid position was created for Forssmann at the Berliner Charité Hospital, working under Ferdinand Sauerbruch, although once Sauerbruch saw his paper, he was dismissed for continuing without his approval. Sauerbruch commented, "You certainly can't begin surgery in that manner". Facing such disciplinary action for self-experimentation, he was initially forced to leave the Charité, but was later re-instated until again being forced to leave in 1932 for not meeting scientific expectations. His surgical skills were noted, however, and he was recommended to another hospital where he worked for a while before leaving in 1933 after marrying Dr. Elsbet Engel, a specialist in urology there. Finding it difficult to get a job with his reputation, he quit cardiology and took up urology. He then went on to study urology under Karl Heusch at the in Berlin. Later, he was appointed Chief of the Surgical Clinic at both the City Hospital at Dresden-Friedrichstadt and the in Berlin.

In November 1679, Hooke began an exchange of letters with Newton, of which the full text is now published. Hooke told Newton that Hooke had been appointed to manage the Royal Society's correspondence, and wished to hear from members about their researches, or their views about the researches of others; and as if to whet Newton's interest, he asked what Newton thought about various matters, giving a whole list, mentioning "compounding the celestial motions of the planets of a direct motion by the tangent and an attractive motion towards the central body", and "my hypothesis of the lawes or causes of springinesse", and then a new hypothesis from Paris about planetary motions (which Hooke described at length), and then efforts to carry out or improve national surveys, the difference of latitude between London and Cambridge, and other items. Newton's reply offered "a fansy of my own" about a terrestrial experiment (not a proposal about celestial motions) which might detect the Earth's motion, by the use of a body first suspended in air and then dropped to let it fall. The main point was to indicate how Newton thought the falling body could experimentally reveal the Earth's motion by its direction of deviation from the vertical, but he went on hypothetically to consider how its motion could continue if the solid Earth had not been in the way (on a spiral path to the centre). Hooke disagreed with Newton's idea of how the body would continue to move. A short further correspondence developed, and towards the end of it Hooke, writing on 6 January 1680 to Newton, communicated his "supposition ... that the Attraction always is in a duplicate proportion to the Distance from the Center Reciprocall, and Consequently that the Velocity will be in a subduplicate proportion to the Attraction and Consequently as Kepler Supposes Reciprocall to the Distance." (Hooke's inference about the velocity was actually incorrect.)

Ryley finds records of the "Degasi"'s crew stating that only three survived the initial crash, but later two out of the three are confirmed dead and one is presumed dead. Ryley also learns of the existence of the 'Precursors', an ancient, advanced alien species that came to planet 4546B approximately one thousand years ago in search of a cure for a highly infectious disease, known as the Kharaa Bacterium. The Precursors discovered Kharaa during the exploration of an unknown planet, and the disease spread due to a failure in quarantine procedures, killing over 140 billion individuals. Investigating thousands of planets in an attempt to find a cure, the Precursors eventually located a species of organism on 4546B they named the Sea Emperor Leviathan, which produced an enzyme that could cure Kharaa. However, the only living Sea Emperor was too old to produce the enzyme in enough potency to have any effect, and the Precursors were unable to force its only eggs to hatch. In an attempt to investigate the egg-hatching process of the Sea Emperor, the Precursors took the egg of a related Leviathan, the fire-breathing Sea Dragon, but the mother destroyed a Precursor research facility and released samples of Kharaa into the planet's ecosystem. Forced to evacuate, the Precursors enabled a facility known as the Quarantine Enforcement Platform, which consists of a large weapon that fires on any ships attempting to leave or land on the planet — including the "Degasi," "Aurora" and "Sunbeam".

The was the first race after the only allowed in-season test at the Mugello Circuit. The RB8 did not enjoy a weekend as successful as its last though, with Webber starting the race eleventh and Vettel seventh. Webber finished in the same place he started and Vettel gained one place to finish sixth after both drivers had to pit for the pit crew to replace the front wings on their cars due to a problem. Two weeks later at the , things were looking far better for the team, as Webber took pole position after Michael Schumacher was penalised. Vettel, for the second race in succession, intentionally did not complete a full timed lap in the final part of qualifying, and started ninth. Webber eventually won the race to take the team's third successive win in the principality, while Vettel moved up to fourth and finished just 1.3 seconds behind the winner. Despite Webber becoming the sixth driver to win a race in the first six races, and the RB8 becoming the only car to win multiple races, it was becoming clearer who the team's rivals for the championship title would be. The McLaren MP4-27, the Ferrari F2012, the Mercedes F1 W03 and the Lotus E20 joined the RB8 near the top of the Constructors' Championship, and looked likely to make a bid for the title; other cars like the Williams FW34 and the Sauber C31 had produced good results, but looked unlikely to make a title challenge. Also, as a consequence of the race, Vettel lost his lead in the Drivers' championship.

"Intra-patera" eruptions occur within volcanic depressions known as "paterae", which generally have flat floors bounded by steep walls. Paterae resemble terrestrial calderas, but it is unknown whether they form when an empty magma chamber collapses, like their terrestrial cousins. One hypothesis suggests that they are produced through the exhumation of volcanic sills, with the overlying material either being blasted out or integrated into the sill. Some paterae display evidence for multiple collapses, similar to the calderas atop Olympus Mons on Mars or Kīlauea on Earth, suggesting that they may occasionally form like volcanic calderas. Because the formation mechanism is still uncertain, the general term for these features uses the Latin descriptor term employed by the International Astronomical Union in naming them, "paterae". Unlike similar features on Earth and Mars, these depressions generally do not lie at the peak of shield volcanoes and are larger, with an average diameter of . Patera depths have been measured for only a few paterae and typically exceed 1 km. The largest volcanic depression on Io is Loki Patera at across. Whatever the formation mechanism, the morphology and distribution of many paterae suggest that they are structurally controlled, with at least half bounded by faults or mountains.

Furthermore, sex-related differences in mental rotation abilities may reflect evolutionary differences. Men assumed the role of hunting and foraging, which necessitates a greater degree of visual-spatial processing than the child-rearing and domestic tasks which women performed. Biologically, males receive higher fetal exposure to androgens than females, and retain these relatively higher levels for life. This difference plays a significant role in human sexual dimorphism, and may be a causal factor in the differences observed regarding mental rotation. Interestingly, women with congenital adrenal hyperplasia (CAH), who are exposed to higher levels of fetal androgen than control women, tend to perform better on the MRT than women with normal amounts of fetal androgen exposure. Additionally, the significant role of hormonal variation between the sexes was supported by a 2004 study, which revealed that testosterone (a principal androgen) level in young men was negatively correlated with the number of errors and response time in the MRT. Therefore, higher levels of testosterone probably contribute to better performance.

For this purpose, by a particular order of the national leader Haydar Aliyev, in 1976, the Department of Astrophysics was established at the Azerbaijan State University. This department played an important role in training qualified personnel in astronomy. In 1981, by the decision of the Cabinet of Ministers, the Shamakhy Astrophysical Observatory was named after the great Azerbaijani astronomer Nasreddin Tusi. In 1973, the Batabat department, located in the Nakhchivan Autonomous Republic, was merged with the ShAO. In 1997, the Aghdara observational station, which operated on the territory of the Nakhchivan Autonomous Republic during the Soviet period and became the proprietorship of the Azerbaijani state after gaining independence, was also transferred to the balance sheet of the ShAO. According to the order of our national leader Haydar Aliyev dated August 7, 2002, "On the establishment of the Nakhchivan branch of the National Academy of Sciences of Azerbaijan," the Batabat Astrophysical Observatory, together with the Aghdara observational station was transferred to the Nakhchivan branch of the National Academy of Sciences of Azerbaijan, and now operates as an independent observatory. Here, processing and analysis of observational materials and research in theoretical astrophysics are carried out. BCB is particularly important in coordinating the observatory activities and its collaboration with other structures and research institutes of ANAS and with the city's universities. Here, dissertations are defended, regular scientific seminars are held, scientific journals of the Observatory are issued, and the official website is managed.

By radically changing both the culture and tools used in technology development, the New Whittle Laboratory is aimed to dramatically cut the time required to achieve net zero flight. Recent pioneering trials at the Whittle Laboratory in collaboration with Rolls-Royce, and funded by the Aerospace Technology Institute, has demonstrated the ability to reduce the time require to design, build and test technologies by a factor of between 10 and 100, from years to months or weeks. This allow research teams to work in a hardware rich environment, failing fast to learn fast. The New Whittle Laboratory is designed to scale this process, acting as a zero carbon technology accelerator. It will act as a demonstrator of this game changing technology development process, allowing it to be replicated to other sectors and around the world. https://www.re-tv.org/reinvigorate/reworking-innovation

In addition to changing environments from disabling to enabling atmospheres, advocates of the social model support the complete integration of disabled people into society. They encourage maximum integration with peers who are not disabled by their environment, especially, but not exclusively, in the school setting. Ultimately, the goal of proponents of the social model is to ensure all people are fully able to enjoy "all human rights and fundamental freedoms". The social model of disability's ideology of "all-inclusive" school environments is not adhered to in the cultural model. Residential schools separate deaf and hard of hearing children from their hearing counterparts. The existence of these schools demonstrate an example of respecting and embracing the totality of the deaf experience rather than dismissing it. While the social model's promotion of inclusion at every level is a great principle, it may not always be the best environment in practice. In the case of deafness, there is a lot a child can miss in a mainstreamed schooling environment. In a poorly constructed mainstreamed environment, fostering relationships with classmates may be difficult and auditory important material shared verbally by teachers may be missed. As a result, the child may fall behind both academically and socially. In residential school settings, these challenges may not be experienced to the same degree, and would allow for deaf children's social and academic lives to instead flourish.

By the time of the Bagnères-de-Bigorre conference, Rossi had already turned his attention toward the astrophysical implications of cosmic ray phenomena, particularly extensive air showers. After Rossi's recognition, in Eritrea, that these events exist, they were extensively studied by Pierre Auger, and by Williams. At this time, the extremely fast response of the newly developed scintillation counters offered a new way to study the structure of air showers. To do this, Rossi enlisted his student, George W. Clark, who completed a PhD in 1952, and Piero Bassi, who was a visitor from the University of Padua. Because solid scintillating material was unavailable, they decided to use terphenyl dissolved in benzine, which is an efficient liquid scintillator. With the aid of three counters deployed on the roof of the MIT Physics building during the winter of 1952/53, they found that shower particles arrived within only one or two meters of a disk, which travels at nearly the speed of light in the direction of the shower axis.

In 1905, Einstein used the quantum theory to explain the photoelectric effect, and in 1913 the Danish physicist Niels Bohr used the same constant to explain the stability of Rutherford's atom as well as the frequencies of light emitted by hydrogen gas. The quantized theory of the atom gave way to a full-scale quantum mechanics in the 1920s. New principles of a "quantum" rather than a "classical" mechanics, formulated in matrix-form by Werner Heisenberg, Max Born, and Pascual Jordan in 1925, were based on the probabilistic relationship between discrete "states" and denied the possibility of causality. Quantum mechanics was extensively developed by Heisenberg, Wolfgang Pauli, Paul Dirac, and Erwin Schrödinger, who established an equivalent theory based on waves in 1926; but Heisenberg's 1927 "uncertainty principle" (indicating the impossibility of precisely and simultaneously measuring position and momentum) and the "Copenhagen interpretation" of quantum mechanics (named after Bohr's home city) continued to deny the possibility of fundamental causality, though opponents such as Einstein would metaphorically assert that "God does not play dice with the universe". The new quantum mechanics became an indispensable tool in the investigation and explanation of phenomena at the atomic level. Also in the 1920s, the Indian scientist Satyendra Nath Bose's work on photons and quantum mechanics provided the foundation for Bose–Einstein statistics, the theory of the Bose–Einstein condensate.
