"Saccharomyces cerevisiae" is a yeast of the phylum "Ascomycota". During vegetative growth that ordinarily occurs when nutrients are abundant, "S. cerevisiae" reproduces by mitosis as diploid cells. However, when starved, these cells undergo meiosis to form haploid spores. Mating occurs when haploid cells of opposite mating types MATa and MATα come into contact. Ruderfer et al. pointed out that, in nature, such contacts are frequent between closely related yeast cells for two reasons. The first is that cells of opposite mating type are present together in the same acus, the sac that contains the cells directly produced by a single meiosis, and these cells can mate with each other. The second reason is that haploid cells of one mating type, upon cell division, often produce cells of the opposite mating type. An analysis of the ancestry of natural "S. cerevisiae" strains concluded that outcrossing occurs very infrequently (only about once every 50,000 cell divisions). The relative rarity in nature of meiotic events that result from outcrossing suggests that the possible long-term benefits of outcrossing (e.g. generation of diversity) are unlikely to be sufficient for generally maintaining sex from one generation to the next. Rather, a short-term benefit, such as meiotic recombinational repair of DNA damages caused by stressful conditions (such as starvation) may be the key to the maintenance of sex in "S. cerevisiae".

There were many predictions of hurricane risk in New Orleans before Hurricane Katrina in August, 2005. In 2001, the "Houston Chronicle" published a story which predicted that a severe hurricane striking New Orleans, "would strand 250,000 people or more, and probably kill one of 10 left behind as the city drowned under of water. Thousands of refugees could land in Houston." Many concerns also focused around the fact that the city's levee system was only designed for hurricanes of no greater intensity than category 3. As it turned out, Katrina was Category 3 when it made landfall and most of New Orleans experienced Category 1 or 2 strength winds. However, due to the slow moving nature of the storm in its pass over New Orleans, several floodwalls lining the shipping and drainage canals in New Orleans collapsed and the resulting flood water from Lake Pontchartrain inundated the city within the two days following the storm, causing costly damage to buildings and resulting in many deaths.

One of the few commercial articulatory speech synthesis systems is the NeXT-based system originally developed and marketed by Trillium Sound Research, a spin-off company of the University of Calgary, where much of the original research was conducted. Following the demise of the various incarnations of NeXT (started by Steve Jobs in the late 1980s and merged with Apple Computer in 1997), the Trillium software was published under a GNU General Public Licence, with work continuing as gnuspeech. The system, first marketed in 1994, provides full articulatory-based text-to-speech conversion using a waveguide or transmission-line analog of the human oral and nasal tracts controlled by Rene Carré's "distinctive region model".

The Boeing X-37B, a reusable uncrewed spacecraft operated by USSF, which is also known as the Orbital Test Vehicle (OTV), has been successfully launched four times from Cape Canaveral. The first four X-37B missions have been launched with Atlas V rockets. Past launch dates for the X-37B spaceplane include April 22, 2010, March 5, 2011, December 11, 2012, and May 20, 2015. The fourth X-37B mission landed at the Kennedy Space Center on May 7, 2017, after 718 days in orbit. The first three X-37B missions all made successful autonomous landings from space to a runway located at Vandenberg Space Force Base in California which was originally designed for Space Shuttle return from orbit operations.

Nietzsche rejected fundamental components of Kant's ethics, particularly his argument that morality, God, and immorality, can be shown through reason. Nietzsche cast suspicion on the use of moral intuition, which Kant used as the foundation of his morality, arguing that it has no normative force in ethics. He further attempted to undermine key concepts in Kant's moral psychology, such as the will and pure reason. Like Kant, Nietzsche developed a concept of autonomy; however, he rejected Kant's idea that valuing our own autonomy requires us to respect the autonomy of others. A naturalist reading of Nietzsche's moral psychology stands contrary to Kant's conception of reason and desire. Under the Kantian model, reason is a fundamentally different motive to desire because it has the capacity to stand back from a situation and make an independent decision. Nietzsche conceives of the self as a social structure of all our different drives and motivations; thus, when it seems that our intellect has made a decision against our drives, it is actually just an alternative drive taking dominance over another. This is in direct contrast with Kant's view of the intellect as opposed to instinct; instead, it is just another instinct. There is thus no self-capable of standing back and making a decision; the decision the self-makes is simply determined by the strongest drive. Kantian commentators have argued that Nietzsche's practical philosophy requires the existence of a self capable of standing back in the Kantian sense. For an individual to create values of their own, which is a key idea in Nietzsche's philosophy, they must be able to conceive of themselves as a unified agent. Even if the agent is influenced by their drives, he must regard them as his own, which undermines Nietzsche's conception of autonomy.

Wilson and Liu suggested intergroup attitudes follow social structure and cultural beliefs, theories, and ideologies developed to make sense of group's place in the social structure and the nature of their relationships with other groups; from this view, SDO is a product rather than a cause of social life. They questioned the invariance hypothesis, and cited their own test relating "strength of gender identification" as a moderator of "gender‐social dominance orientation relationship", reporting that group identification was associated with increased dominance orientation in males but decreased dominance orientation in females. Pratto, Sidanius and Levin denied that any claim was made that SDO measures are independent of social identity context, and that methodologically, “it would obviously make no sense to compare the SDO levels of female members of death squads to those of male social workers, or, less dramatically, to compare the SDO levels of men identifying with female gender roles to those of women identifying with male gender roles”. The hypothesized evolutionary predispositions of one gender towards SDO was not intended by the SDT authors to imply that nothing can be done about gender inequality or domination patterns, and that the theory provides unique approaches for attenuating those predispositions and their social manifestations.

The original model of the SF.260 was powered by a single Lycoming O-540 engine, capable of providing 260 hp. The standard engine made use of a carburetor, while a fuel injected engine was available as an optional extra. The SF.260 has been described as having the power to be immune to the gyration-like effects of turbulence and possessing a high rate of climb. During the 1980s, aerospace publication "Flying" stated the SF.260 to be: "the fastest normally aspirated piston single in production". The SF.260 holds the airspeed records for aircraft in its class over the and closed circuits. Later-built models often made use of turboprop engines; the initial model to be equipped as such, designated as the "SF.260TP", was powered by a single Allison Model 250 engine, flat-rated at 350 shp.

Hofmann was multilingual and published extensively, particularly about his work on coal tar and its derivatives. In 1865 Hofmann published "An Introduction to Modern Chemistry", summarising type theory and emerging ideas about chemical structure. Type theory modelled four inorganic molecules, hydrogen, hydrogen chloride, water, and ammonia, and used them as a basis for systematising and categorising both organic and inorganic compounds by exploring the substitution of one or more atoms of hydrogen for an equivalent atom or group. Hofmann himself had focused on researching ammonia, but discussed all four models in his book. In it, he also first introduced the term valence, under its longer variant quantivalence, to describe the combining capacity of an atom. His textbook strongly influenced introductory textbooks in both Europe and the United States.

In December 1970, the Office of Management and Budget recommended the cancellation of NERVA and Skylab, but Nixon was reluctant to do so, as their cancellation could cost up to 20,000 jobs, mostly in California, a state that Nixon felt he needed to carry in the 1972 election. He decided to keep it alive at a low funding level, and cancel Apollo 17 instead. The concern about Apollo 17 was about the political fallout if it failed rather than the cost, and this was ultimately addressed by postponing it to December 1972, after the election. When Nixon tried to kill NERVA in 1971, Senator Anderson and Senator Margaret Chase Smith instead killed Nixon's pet project, the Boeing 2707 supersonic transport (SST). This was a stunning defeat for the president. In the budget for FY 1972, funding for the shuttle was cut, but NERVA and Apollo 17 survived. Although NERVA's budget request was only $17.4 million, Congress allocated $69 million; Nixon only spent $29 million of it.

In order to combat some of the "in vivo" limitations of RNA aptamers, various modifications can be added to the nucleotides to aid in efficacy of the aptamer. For instance, a polyethylene glycol (PEG) moiety can be attached to increase the size of the aptamer, thereby preventing its removal from the bloodstream by the renal glomerulus. However, PEG has been implicated in allergic reactions during "in vivo" testing. Furthermore, modifications can be added to prevent nuclease degradation, such as a 2’ fluoro or amino group as well as a 3’ inverted thymidine. Additionally, the aptamer can be synthesized so that the ribose sugar is in the L-form instead of the D-form, further preventing nuclease recognition. Such aptamers are known as Spiegelmers. In order to prevent Toll-like receptor pathway activation, the cytosine nucleobases within the aptamer can be methylated. Nevertheless, despite these potential solutions to reduced "in vivo" efficacy, it is possible that chemically modifying the aptamer may weaken its binding affinity towards its target.

This type of system is significantly more expensive than a zone system. The basic system may start with maps from the US Census Bureau or a county assessor's office. The quality of these maps may be good but will not be ideal for dispatching. There would normally be one or more persons on staff who would deal with data changes from new development, new streets, or data quality problems. The person would compile addresses and generate street centerlines in mapping software. Geocoding varies in accuracy depending on data sources and vendors. It normally takes years of work and planning before a system is implemented. Modern geocoded systems will often display service vehicle locations, the location of service calls, and the locations of callers on a map. This helps to disambiguate calls for service and reduces the likelihood of dispatching two reports of a single call for service as two separate calls.

The activity of SINEs however has genetic vestiges which do not seem to play a significant role, positive or negative, and manifest themselves in the genome as pseudogenes. SINEs however should not be mistaken as RNA pseudogenes. In general, pseudogenes are generated when processed mRNAs of protein-coding genes are reverse-transcribed and incorporated back into the genome (RNA pseudogenes are reverse transcribed RNA genes). Pseudogenes are generally functionless as they descend from processed RNAs independent of their evolutionary-context which includes introns and different regulatory elements which enable transcription and processing. These pseudogenes, though non-functional may in some cases still possess promoters, CpG islands, and other features which enable transcription; they thus can still be transcribed and may possess a role in the regulation of gene expression (like SINEs and other non-coding elements). Pseudogenes thus differ from SINEs in that they are derived from transcribed- functional RNA whereas SINEs are DNA elements which retrotranspose by co-opting RNA genes transcriptional machinery. However, there are studies which suggest that retro-transposable elements such as short-interspersed nuclear elements are not only capable of copying themselves in alternate regions in the genome but are also able to do so for random genes too. Thus SINEs can be playing a vital role in the generation of pseudogenes, which themselves are known to be involved in regulatory networks. This is perhaps another means by which SINEs have been able to influence and contribute to gene-regulation.

Gene therapy has been explored as a method to treat glioblastoma, and while animal models and early-phase clinical trials have been successful, as of 2017, all gene-therapy drugs that had been tested in phase-III clinical trials for glioblastoma had failed. Scientists have developed the core–shell nanostructured LPLNP-PPT (long persistent luminescence nanoparticles. PPT refers to polyetherimide, PEG and trans-activator of transcription, and TRAIL is the human tumor necrosis factor-related apoptosis-induced ligand) for effective gene delivery and tracking, with positive results. This is a TRAIL ligand that has been encoded to induce apoptosis of cancer cells, more specifically glioblastomas. Although this study was still in clinical trials in 2017, it has shown diagnostic and therapeutic functionalities, and will open great interest for clinical applications in stem-cell-based therapy.

An HDF counterpart in the southern celestial hemisphere was created in 1998: the HDF-South (HDF-S). Created using a similar observing strategy, the HDF-S was very similar in appearance to the original HDF. This supports the cosmological principle that at its largest scale the Universe is homogeneous. The HDF-S survey used the Space Telescope Imaging Spectrograph (STIS) and the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) instruments installed on the HST in 1997; the region of the original Hubble Deep Field (HDF-N) has since been re-observed several times using WFPC2, as well as by the NICMOS and STIS instruments. Several supernova events were detected by comparing the first and second epoch observations of the HDF-N.

Apollo 7 was launched on October 11, 1968, from Cape Kennedy Air Force Station, Florida, and splashed down in the Atlantic Ocean eleven days later. Extensive testing of the CSM took place, and also the first live television broadcast from an American spacecraft. Despite tension between the crew and ground controllers, the mission was a complete technical success, giving NASA the confidence to send Apollo 8 into orbit around the Moon two months later. In part because of these tensions, none of the crew flew in space again, though Schirra had already announced he would retire from NASA after the flight. Apollo7 fulfilled Apollo1's mission of testing the CSM in low Earth orbit, and was a significant step towards NASA's goal of landing astronauts on the Moon.

Engineered gene drives using CRISPR-cas9 are currently being tested and have been proposed as strategies to eliminate invasive species and disease vectors. By genetically modifying an organism to express an endogenous sequence-specific endonuclease, a target (such as a fertility gene) can be cleaved on the opposite chromosome. A DSB at the target leads to homologous repair which effectively renders the organism homozygous for the desired target sequence. This strategy, known as a homing drive, can suppress a population by affecting a critical gene or inducing recessive sterility. However, if such a system were released into the wild, the CRISPR-cas9 system would remain function indefinitely. With every subsequent generation, off-target mutations would become increasingly likely and the effects of these mutations on a species would be stochastic. Off-target mutations could disable the suppressive qualities of a gene drive while maintaining the endonuclease expression. In such a situation there would be an increased risk of gene flow between the target species and other species likely leading to undesired outcomes.

Crumpler first practiced medicine in Boston. She primarily cared for poor African-American women and children. After the end of the American Civil War (1861–1865), she moved to Richmond, Virginia, believing it to be an ideal way to provide missionary service, as well as to gain more experience learning about diseases that affected women and children. She said of that time, "During my stay there nearly every hour was improved in that sphere of labor. The last quarter of the year 1866, I was enabled... to have access each day to a very large number of the indigent, and others of different classes, in a population of over 30,000 colored."

Through testing with Arabidopsis thaliana (A plant considered a model organism for plant genetic studies) genes including MAX1 and MAX2 have been found to affect growth of lateral shoots. Gene knockouts of these genes cause abnormal proliferation of the plants affected, implying they are used for repressing said growth in wild type plants. Another set of experiments with Arabidopsis thaliana testing genes in the plant hormone florigen, two genes FT and TSF (which are abbreviations for Flowering Locus T, and Twin Sister of FT) when knocked out, appear to affect lateral shoot in a negative fashion. These mutants cause slower growth and improper formation of lateral shoots, which could also mean that lateral shoots are important to florigen's function. Along with general growth there are also transcription factors that directly effect the production of additional lateral shoots like the TCP family (also known as Teosinte branched 1/cycloidea/proliferating cell factor) which are plant specific proteins that suppress lateral shoot branching. Additionally the TCP family has been found to be partially responsible for inhibiting the cell's Growth hormone–releasing hormone (GHRF) which means it also inhibits cell proliferation.

MUSE system mainly serves as a low-cost alternative to traditional histological analysis for cancer diagnostics with simpler and less time-consuming techniques. By integrating with microscopy and fresh tissue fluorescence staining into an automated optical system, the overall acquiring time needed for getting digital images with diagnostic values can be much shortened into scale of minutes comparing with conventional pathology, where general procedure can take from hours to days. The color-mapping techniques that correlated fluorescence staining to traditional H&E staining provide the same visual representation to pathologists based on existing knowledge system with no need of additional training on image recognition.

Development of the spectrophotometer also had direct relevance to the war effort. For example, the role of vitamins in health was being studied, and scientists wanted to identify Vitamin A-rich foods to keep soldiers healthy. Previous methods involved feeding rats for several weeks, then performing a biopsy to estimate Vitamin A levels. The DU spectrophotometer yielded better results in a matter of minutes. The DU spectrophotometer was also an important tool for scientists studying and producing the new wonder drug penicillin. By the end of the war, American pharmaceutical companies were producing 650 billion units of penicillin each month. Much of the work done in this area during World War II was kept secret until after the war.

Comparison of the crystal structures of the T and R forms of ATCase show that it swells in size during the allosteric transition, and that the catalytic subunits condense during this process. The two catalytic trimers move apart along the threefold axis by 12 Å, and they rotate about this axis by 5° each, ultimately leading to a reorientation of the regulatory subunits around their twofold axis by 15°. This quaternary structure change is associated with alterations in inter-subunit and inter-domain interactions. The interaction between subunits C1-C4 and R1 is extensively modified during this conversion. In particular, there is large movement of amino acid residues 230-254, known collectively as the 240s loop. These residues are located at the cleft between the carbamoyl phosphate and aspartate domains at the C1-C4 interface. The overall outcome of these structural changes is that the two domains of each catalytic chain come closer together, ensuring a better contact with the substrates or their analogues.

During the Last Glacial Maximum, much of the world was cold, dry, and inhospitable, with frequent storms and a dust-laden atmosphere. The dustiness of the atmosphere is a prominent feature in ice cores; dust levels were as much as 20 to 25 times greater than now. This was probably due to a number of factors: reduced vegetation, stronger global winds, and less precipitation to clear dust from the atmosphere. The massive sheets of ice locked away water, lowering the sea level, exposing continental shelves, joining land masses together, and creating extensive coastal plains. During the last glacial maximum, 21,000 years ago, the sea level was about 125 meters (about 410 feet) lower than it is today.

It had been suspected this system would be of little use in practice. When that turned out to be the case, the RAF turned to an entirely different system that was also being planned. This consisted of a set of tracking stations using HF/DF radio direction finders. Their aircraft radios were modified to send out a 1 kHz tone for 14 seconds every minute, allowing the stations ample time to measure the aircraft's bearing. Several such stations were assigned to each "sector" of the air defence system, and sent their measurements to a plotting station at sector headquarters, who used triangulation to determine the aircraft's location. Known as "pip-squeak", the system worked, but was labour-intensive and did not display its information directly to the radar operators. A system that worked directly with the radar was clearly desirable.

Constructing CCS units is capital intensive. The additional costs of a large-scale CCS demonstration project are estimated to be €0.5–1.1 billion per project over the project lifetime. Other applications are possible. CCS trials for coal-fired plants in the early 21st century were economically unviable in most countries, including China, in part because revenue from enhanced oil recovery collapsed with the 2020 oil price collapse. A carbon price of at least 100 euros per tonne CO is estimated to be needed to make industrial CCS viable, together with carbon tariffs. But, as of mid-2022, the EU Allowance had never reached that price and the Carbon Border Adjustment Mechanism had not yet been implemented. However a company making small modules claims it can get well below that price by mass production by 2022.

The feasibility of a plutonium bomb had been questioned in 1942. James Conant heard on 14 November from Wallace Akers, the director of the British Tube Alloys project, that James Chadwick had "concluded that plutonium might not be a practical fissionable material for weapons because of impurities." Conant consulted Ernest Lawrence and Arthur Compton, who acknowledged that their scientists at Berkeley and Chicago respectively knew about the problem, but could offer no ready solution. Conant informed the director of the Manhattan Project, Brigadier General Leslie R. Groves, Jr., who in turn assembled a special committee consisting of Lawrence, Compton, Oppenheimer, and McMillan to examine the issue. The committee concluded that any problems could be overcome by requiring higher purity.

Worst-case tolerance analysis is the traditional type of tolerance stackup calculation. The individual variables are placed at their tolerance limits in order to make the measurement as large or as small as possible. The worst-case model does not consider the distribution of the individual variables, but rather that those variables do not exceed their respective specified limits. This model predicts the maximum expected variation of the measurement. Designing to worst-case tolerance requirements guarantees 100 percent of the parts will assemble and function properly, regardless of the actual component variation. The major drawback is that the worst-case model often requires very tight individual component tolerances. The obvious result is expensive manufacturing and inspection processes and/or high scrap rates. Worst-case tolerancing is often required by the customer for critical mechanical interfaces and spare part replacement interfaces. When worst-case tolerancing is not a contract requirement, properly applied statistical tolerancing can ensure acceptable assembly yields with increased component tolerances and lower fabrication costs.

McClusky's decision to continue the search and his judgment, in the opinion of Admiral Chester Nimitz, "decided the fate of our carrier task force and our forces at Midway ..." All three American dive-bomber squadrons (VB-6, VS-6, and VB-3) arrived almost simultaneously at the perfect time, locations and altitudes to attack. Most of the Japanese CAP was directing its attention to the torpedo planes of VT-3 and was out of position; meanwhile, armed Japanese strike aircraft filled the hangar decks, fuel hoses snaked across the decks as refueling operations were hastily being completed, and the repeated change of ordnance meant that bombs and torpedoes were stacked around the hangars, rather than stowed safely in the magazines, making the Japanese carriers extraordinarily vulnerable.

The tectonic deformations on Venus occur on a variety of scales, the smallest of which are related to linear fractures or faults. In many areas these faults appear as networks of parallel lines. Small, discontinuous mountain crests are found which resemble those on the Moon and Mars. The effects of extensive tectonism are shown by the presence of "normal faults", where the crust has sunk in one area relative to the surrounding rock, and superficial fractures. Radar imaging shows that these types of deformation are concentrated in belts located in the equatorial zones and at high southern latitudes. These belts are hundreds of kilometers wide and appear to interconnect across the whole of the planet, forming a global network associated with the distribution of volcanoes.

In the essay, first published in "The Rhinoceros Times", Card attributed Obama's success to being a "black man who talks like a white man (that's what they mean by calling him "articulate" and a "great speaker")." The essay drew criticism from journalists for its allusions to Obama's race and its reference to "urban gangs". Vice author Dave Schilling featured the article in his "This Week in Racism" roundup several months after its publication.

This skink has a snout to vent length of around 113mm as a maximum, however has an average SVL of 75mm. This skink is a medium-sized skink and the name corresponds well with the species for its ability to practically ‘swim’ over the sand to chase and catch its prey. The tail length varies but is up to 171% longer than the SVL. They are a very distinct skink in their looks, although are similar in many ways to the "E. fasciolatus". The Broad Banded Sand-Swimmer can be identified based upon the pattern of the caudal bands that it possesses and the number of caudal bands it possesses to distinguish between other sand-swimmers which can be seen in image 3. These skinks have between 19 and 32 bands on the tail, however the Narrow Banded possesses more (between 35 and 40). On the nape, the broad banded possesses 8-14 bands that whereas the narrow-banded swimmer 10-19 narrow bands on its nape. The bands on the body are much broader than those of the narrow banded, and they are generally less regular than the narrow banded. If the skink has lost its tail in the past, using the bands to distinguish the skink is unable to be used, as once the tail is regrown, it does not possess the caudal bands. This skink possesses a snout that is less depressed than that of the "E. fasciolatus". The colour of these skinks can be a pale brown to dark reddish colour, with the young hatchlings having a bright yellow colour and some of these variances can be seen in images 1 and 2. The scales of this skink are very shiny and has five toes on each of the animal's feet- both the forelimbs and hindlimbs. Another way that the E.richardsonii can be identified, is through the parietal scales being in contact rather than being separated. This is also a way to tell if the skink has a transparent lower eyelid as skinks with round eyes do not have this feature, however when they are hold an elliptical eye shape.

With a population of roughly 6 million, between 1914-1918 over 250,000 South Africans of all races voluntarily served their country. Thousands more served in the British Army directly, with over 3,000 joining the British Royal Flying Corps and over 100 volunteering for the Royal Navy. It is likely that near 50% of white men of military age served during the war. More than 146,000 whites, 83,000 black Africans and 2,500 Coloureds and Asians served in either German South-West Africa, East Africa, the Middle East, or on the Western Front in Europe. Suffering roughly 19,000 casualties, over 7,000 South Africans were killed and nearly 12,000 were wounded during the course of the war. won the Victoria Cross for gallantry, the Empire’s highest and most prestigious military medal.

Since the 1970s, clinical psychology has continued growing into a robust profession and academic field of study. Although the exact number of practicing clinical psychologists is unknown, it is estimated that between 1974 and 1990, the number in the US grew from 20,000 to 63,000. Clinical psychologists continue to be experts in assessment and psychotherapy while expanding their focus to address issues of gerontology, sports, and the criminal justice system to name a few. One important field is health psychology, the fastest-growing employment setting for clinical psychologists in the past decade. Other major changes include the impact of managed care on mental health care; an increasing realization of the importance of knowledge relating to multicultural and diverse populations; and emerging privileges to prescribe psychotropic medication.

In mid-1988, Airbus engineers led by Jean Roeder began work in secret on the development of an ultra-high-capacity airliner (UHCA), both to complete its own range of products and to break the dominance that Boeing had enjoyed in this market segment since the early 1970s with its 747. McDonnell Douglas unsuccessfully offered its double-deck MD-12 concept for sale. Lockheed was exploring the possibility for a Very Large Subsonic Transport. Roeder was given approval for further evaluations of the UHCA after a formal presentation to the President and CEO in June 1990.

Energy harvesting is most often more effective in regards to cost and resource utilization when done on a local but combined scale, for example a group of houses, cohousing, local district or village rather than an individual house basis. An energy benefit of such localized energy harvesting is the virtual elimination of electrical transmission and electricity distribution losses. On-site energy harvesting such as with roof top mounted solar panels eliminates these transmission losses entirely. Energy harvesting in commercial and industrial applications should benefit from the topography of each location. However, a site that is free of shade can generate large amounts of solar powered electricity from the building's roof and almost any site can use geothermal or air-sourced heat pumps. The production of goods under net zero fossil energy consumption requires locations of geothermal, microhydro, solar, and wind resources to sustain the concept.

Silicon oxide presents an interesting case of resistance switching. Two distinct modes of intrinsic switching have been reported - surface-based, in which conductive silicon filaments are generated at exposed edges (which may be internal—within pores—or external—on the surface of mesa structures), and bulk switching, in which oxygen vacancy filaments are generated within the bulk of the oxide. The former mode suffers from oxidation of the filaments in air, requiring hermetic sealing to enable switching. The latter requires no sealing. In 2014 researchers from Rice University announced a silicon filament-based device that used a porous silicon oxide dielectric with no external edge structure - rather, filaments were formed at internal edges within pores. Devices can be manufactured at room temperature and have a sub-2V forming voltage, high on-off ratio, low power consumption, nine-bit capacity per cell, high switching speeds and good endurance. Problems with their inoperability in air can be overcome by hermetic sealing of devices. Bulk switching in silicon oxide, pioneered by researchers at UCL (University College London) since 2012, offers low electroforming voltages (2.5V), switching voltages around 1V, switching times in the nanoseconds regime, and more than 10,000,000 cycles without device failure - all in ambient conditions.

The Mark II was constructed with high-speed electromagnetic relays instead of the electro-mechanical counters used in the Mark I, making it much faster than its predecessor. It weighed and occupied over of floor space. Its addition time was 0.125 seconds (8 Hz) and the multiplication time was 0.750 seconds. This was a factor of 2.6 faster for addition and a factor of 8 faster for multiplication compared to the Mark I. It was the second machine (after the Bell Labs Relay Calculator) to have floating-point hardware. A unique feature of the Mark II is that it had built-in hardware for several functions such as the reciprocal, square root, logarithm, exponential, and some trigonometric functions. These took between five and twelve seconds to execute. Additionally, the Mark II was actually composed of two sub-computers that could either work in tandem or operate on separate functions, to cross-check results and debug malfunctions.

The 2005 discovery by archaeologist Eilat Mazar of a Large Stone Structure, which she dated to the tenth century BCE, would be evidence of buildings in Jerusalem of a size appropriate to the capital of a centralized kingdom at that time. Others, most notably Israel Finkelstein of Tel Aviv University, argue that the structure could, for the most part, be from the much later Hasmonean period. However, new evidence continues to emerge from the dig. Mazar's date is supported by 10th century imported luxury goods found within the Large Stone Structure, including two Phoenician-style ivory inlays once attached to iron objects. Comparable objects found in a Phoenician tomb at Achziv suggest that they may have decorated a sword handle. A quantity of luxury round, carinated bowls with red slip and hand burnishing support both the tenth century date and a sophisticated, urban lifestyle. A bone has been radiocarbon dated by Elisabetta Boaretto at the Weizmann Institute, showing a probable date between 1050 and 780 BCE. A large section of a "delicate and elegant" black-on-red jug, also found in the structure, is of a kind dated to the second half of the tenth century BCE.

The works of Givental and of Lian−Liu−Yau confirm a prediction made by the more fundamental mirror symmetry conjecture of how three-dimensional Calabi−Yau manifolds can be paired off. However, their works do not logically depend on the conjecture itself, and so have no immediate bearing on its validity. With Andrew Strominger and Eric Zaslow, Yau proposed a geometric picture of how mirror symmetry might be systematically understood and proved to be true. Their idea is that a Calabi−Yau manifold with complex dimension three should be foliated by "special Lagrangian" tori, which are certain types of three-dimensional minimal submanifolds of the six-dimensional Riemannian manifold underlying the Calabi−Yau structure. Mirror manifolds would then be characterized, in terms of this conjectural structure, by having "dual" foliations. The Strominger−Yau−Zaslow (SYZ) proposal has been modified and developed in various ways since 1996. The conceptual picture that it provides has had a significant influence in the study of mirror symmetry, and research on its various aspects is currently an active field. It can be contrasted with the alternative homological mirror symmetry proposal by Maxim Kontsevich. The viewpoint of the SYZ conjecture is on geometric phenomena in Calabi–Yau spaces, while Kontsevich's conjecture abstracts the problem to deal with purely algebraic structures and category theory.

Various cellular reactions to ultrasound indicate the mechanism of molecular uptake via endocytosis. These observed reactionary phenomena include ion exchange, hydrogen peroxide, and cell intracellular calcium concentration. Studies have used patch clamping techniques to monitor membrane potential ion exchange for the role of endocytosis in sonoporation. Ultrasound application to cells and adjacent microbubbles was shown to produce marked cell membrane hyperpolarization along with progressive intracellular calcium increase, which is believed to be a consequence of calcium channels opening in response to microbubble oscillations. These findings act as support for ultrasound application inducing calcium-mediated uncoating of clathrin-coated pits seen in traditional endocytosis pathways. Other work reported sonoporation induced the formation of hydrogen peroxide, a cellular reaction that is also known to be involved with endocytosis.

Prion diseases, also called transmissible spongiform encephalopathies (TSEs), are neurodegenerative diseases of the brain thought to be caused by a protein that converts to an abnormal form called a prion. GSS is a very rare TSE, making its genetic origin nearly impossible to determine. It is also challenging to find any patients with GSS, as the disease tends to be underreported, due to its clinical similarity to other diseases, and has been found in only a few countries. In 1989, the first mutation of the prion protein gene was identified in a GSS family. The largest of these families affected by GSS is the Indiana Kindred, spanning over 8 generations, and includes over 3,000 people, with 57 individuals known to be affected. GSS was later realized to have many different gene mutation types, varying in symptom severity, timing and progression. Doctors in different parts of the world are in the process of uncovering more generations and families who have the mutation.

One hypothesis that contradicts the automaticity of AGL is the "mere exposure effect". The mere exposure effect is increased affect towards a stimulus that is the result of nonreinforced, repeated exposure to the stimulus. Results from over 200 experiments on this effect indicate that there is a positive relationship between mean "goodness" rating and frequency of stimulus exposure. Stimuli for these experiments included line drawings, polygons and nonsense words (which are types of stimuli used in AGL research). These experiments exposed participants to each stimulus up to 25 times. Following each exposure participants were asked to rate the degree to which each stimulus suggested "good" vs. "bad" effect on a 7-point scale. In addition to the main pattern of results, it was also found in several experiments that participants rated higher positive affect for previously exposed items than for novel items. Since implicit cognition should not reference previous study episodes, the effects on affect ratings should not have been observed if processing of this stimuli is truly implicit. The results of these experiments suggests that different categorization of the strings may occur due to differences in affect associated with the strings and not due to implicitly learned grammar rules.

AutoAnalyzers were used mainly for routine repetitive medical laboratory analyses, but they had been replaced during the last years more and more by discrete working systems which allow lower reagent consumption. These instruments typically determine levels of albumin, alkaline phosphatase, aspartate transaminase (AST), blood urea nitrogen, bilirubin, calcium, cholesterol, creatinine, glucose, inorganic phosphorus, proteins, and uric acid in blood serum or other bodily samples. AutoAnalyzers automate repetitive sample analysis steps which would otherwise be done manually by a technician, for such medical tests as the ones mentioned previously. This way, an AutoAnalyzer can analyze hundreds of samples every day with one operating technician. Early AutoAnalyzer instruments each tested multiple samples sequentially for individual analytes. Later model AutoAnalyzers such as the SMAC tested for multiple analytes simultaneously in the samples.

On the other hand, this derivation reveals the significant approximation in assuming spherical clusters with formula_120. In reality, the configuration integral formula_89 contains contributions from the full set of particle coordinates formula_122, thus including deviations from spherical shape as well as cluster degrees of freedom such as translation, vibration, and rotation. Various attempts have been made to include these effects in the calculation of formula_89, although the interpretation and application of these extended theories has been debated. A common feature is the addition of a logarithmic correction formula_124 to formula_125, which plays an important role near the critical point of the fluid.

At birth, boys outnumber girls with the ratio of 105 or 106 male to 100 female children. However, after conception, biology favors women. Research has shown that if men and women received similar nutrition, medical attention, and general health care, women would live longer than men. This is because women, on a whole, are much more resistant to diseases and much less prone to debilitating genetic conditions. However, despite medical and scientific research that shows that when given the same care as males, females tend to have better survival rates than males, the ratio of women to men in developing regions such as South Asia, West Asia, and China can be as low as 0.94, or even lower. This deviation from the natural male to female sex ratio has been described by Indian philosopher and economist Amartya Sen as the "missing women" phenomenon. According to the 2012 World Development Report, the number of missing women is estimated to be about 1.5 million women per year, with a majority of the women missing in India and China.

Both "Ureaplasma urealyticum" and "Ureaplasma parvum" have been identified as important human pathogens, causing infection in the urogenital tract and, rarely, at distal sites. Their role in neonatal disease and adverse pregnancy outcomes has been well established, and semantic classifications are changing to reflect the nature of the detrimental outcomes these infections are associated with. In the 2010s, "Mycoplasma genitalium" has been re-classified as an STI, and it is likely that with more research, "Ureaplasma spp". will follow this trend. Similar to other pathogens such as "Chlamydia trachomatis", infection with "Ureaplasma spp." is associated with adverse fertility outcomes in both men and women. Both cause non-gonococcal urethritis. "Ureaplasma spp." were implicated in conditions such as prostatitis and chronic pelvic pain syndrome as early as the 1980s. Research in women has lagged several decades behind, but it is now becoming more clear how "Ureaplasma spp." contribute to etiologies such as interstitial cystitis/painful bladder syndrome. "Ureaplasma spp." are associated with alterations in host environment that increase susceptibility to other infections such as bacterial vaginosis and vaginal candidiasis. "Ureaplasma spp." can cause reactive arthritis as well as directly infect the synovium. Some case studies have suggested a causative role in complex regional pain syndrome/reflex sympathetic dystrophy syndrome.

Dam building peaked in the 1960s and few dams were built in the 1970s. The growing awareness of environmental issues with dams saw the removal of some older and smaller dams and the installation of fish ladders at others. The enormous Rampart Dam was canceled in 1967 due to environmental and economic concerns. Instead of new dams, repowering old stations has increased the capacity of several facilities. For instance, Hoover Dam replaced its generators between 1986 and 1993. The need to alter downstream waterflow for ecological reasons (eliminating invasive species, sedimentation, etc.) has led to regulated seasonal drawdowns at some dams, changing the availability of water for power generation. Droughts and increased agricultural use of water can also lead to generation limits.

Influenza viruses, like all viruses in the family Orthomyxoviridae, are enveloped RNA viruses with single stranded genomes. The antigens, matrix protein (M1) and nucleoprotein (NP), are used to determine if an influenza virus is type A, B, C, or D. The M1 protein is required for virus assembly and NP functions in transcription and replication. These viruses also contain proteins on the surface of the cell membrane called glycoproteins. Type A and B have two glycoproteins: hemagglutinin (HA) and neuraminidase (NA). Types C and D have only one glycoprotein: hemagglutinin-esterase fusion (HEF). These glycoproteins allow for attachment and fusion of viral and cellular membranes. Fusion of these membranes allows the viral proteins and genome to be released into the host cell, which then causes the infection. Types C and D are the only influenza viruses to express the enzyme esterase. This enzyme is similar to the enzyme neuraminidase produced by Types A and B in that they both function in destroying the host cell receptors. Glycoproteins may undergo mutations (antigenic drift) or reassortment in which a new HA or NA is produced (antigenic shift). Influenza viruses C and D are only capable of antigenic drift whereas Type A undergoes antigenic shift, as well. When either of these processes occur, the antibodies formed by the immune system no longer protect against these altered glycoproteins. Because of this, viruses continually cause infections.

The engines were stymied by low methane header tank pressure during the landing attempt and led to a hard impact with the landing pad. Because SpaceX had violated its launch license and ignored warnings of worsening shock wave damage, the Federal Aviation Administration performed a two-month investigation of the incident.

While not always able to avoid contact with the escorts, the threat of mass attacks and later the "company front" (eight abreast) assaults by armored "Sturmgruppe" Fw 190As brought an urgency to attacking the Luftwaffe wherever it could be found, either in the air or on the ground. Beginning in late February 1944, 8th Air Force fighter units began systematic strafing attacks on German airfields with increasing frequency and intensity throughout the spring, with the objective of gaining air supremacy over the Normandy battlefield. In general, these were conducted by units returning from escort missions but, beginning in March, many groups also were assigned airfield attacks instead of bomber support. The P-51, particularly with the advent of the K-14 Gyro gunsight and the development of "Clobber Colleges" for the training of fighter pilots in fall 1944, was a decisive element in Allied countermeasures against the "Jagdverbände".

Electrophoresis is the mass flux of charged particles under an electric field. Both processes work at the same time but in a counter current manner. The charged particles are driven by electrophoresis flow from the cathode to the anode while electrolytic solution flows from the anode to the cathode. Of the two main processes electrophoresis (or electromigration) is more dominant than electroosmosis. Electrophoresis serves as the driving factor that induces the flow of electroosmosis in the opposite direction. Electromigration also serves as the major component for ionic contaminant removal. For electromigration to occur absorbed material must be dissolved to an ionic form whether they are metals, organic or inorganic particles. Electroosmotic flow between the electrodes promotes the development of a low-pH environment in the soil. This low pH environment inhibits metallic contaminants from being sorbed onto soil particle surfaces which aids in the formation of compounds making electrokinetics possible. By this thought it is possible to acidify the soil and induce the release of absorbed heavy metals.

The correlation between low sunspot activity and cold winters in England has been analyzed using the longest existing surface temperature record, the Central England Temperature record. A potential explanation of this has been offered by observations by NASA's Solar Radiation and Climate Experiment, which suggest that solar ultraviolet light output is more variable over the course of the solar cycle than scientists had previously thought. A 2011 study found that low solar activity was linked to jet stream behavior, resulting in mild winters in some places (southern Europe and Canada/Greenland) and colder winters in others (northern Europe and the United States). In Europe, examples of very cold winters are 1683–84, 1694–95, and the winter of 1708–09.

While the MiG-29's true capabilities could only be estimated from the time it first appeared In 1977 until the mid-1980s, a combination of persistent intelligence and increasing access afforded by the Soviet foreign sales effort allowed a true appreciation of its capabilities. Early MiG-29s were very agile aircraft, capable of rivaling the performance of contemporary F-18 and F-16 aircraft. However, their relatively low fuel capacity relegated them to short-range air defense missions. Lacking HOTAS and an inter-aircraft data link, and requiring a very intensive "heads-down" approach to operating cockpit controls, the early MiG-29 denied pilots the kind of situational awareness routinely enjoyed by pilots operating comparable US aircraft. Analysts and Western pilots who flew examples of the MiG-29 thought this likely prevented even very good pilots from harnessing the plane's full combat capability. Later MiG-29s were upgraded to improve their capabilities.

Slides are available as photographic positive or negative prints to best fit the illumination technique used in various testing methods. A less expensive, abbreviated version omits the two tiniest groups at the center of the pattern (groups number 8 and 9), since the lithography at that scale is costly, and the group elements represent resolution beyond the design of many imaging applications.

With a nod to a local runner who was notorious for his demanding workouts, Collins said, "Whoever finishes first, we'll call "him" the Iron Man." Each of the racers had their own support crew to supply water, food and encouragement during the event. Of the fifteen men to start off in the early morning on February 18, 1978, twelve completed the race. Gordon Haller, a US Navy Communications Specialist, was the first to earn the title Ironman by completing the course with a time of 11 hours, 46 minutes, 58 seconds. The runner-up John Dunbar, a US Navy SEAL, led after the second transition and had a chance to win but ran out of water on the marathon course; his support crew resorted to giving him beer instead.

Schenkerian analysis is a method of musical analysis of tonal music based on the theories of Heinrich Schenker (1868–1935). The goal of a Schenkerian analysis is to interpret the underlying structure of a tonal work and to help reading the score according to that structure. The theory's basic tenets can be viewed as a way of defining tonality in music. A Schenkerian analysis of a passage of music shows hierarchical relationships among its pitches, and draws conclusions about the structure of the passage from this hierarchy. The analysis makes use of a specialized symbolic form of musical notation that Schenker devised to demonstrate various techniques of elaboration. The most fundamental concept of Schenker's theory of tonality may be that of "tonal space". The intervals between the notes of the tonic triad form a "tonal space" that is filled with passing and neighbour notes, producing new triads and new tonal spaces, open for further elaborations until the surface of the work (the score) is reached.

The early Oak Ridge's chemistry designs were not concerned with proliferation and aimed for fast breeding. They planned to separate and store protactinium-233, so it could decay to uranium-233 without being destroyed by neutron capture in the reactor. With a half-life of 27 days, 2 months of storage would assure that 75% of the Pa decays to U fuel. The protactinium removal step is not required per se for a LFTR. Alternate solutions are operating at a lower power density and thus a larger fissile inventory (for 1 or 1.5 fluid) or a larger blanket (for 2 fluid). Also a harder neutron spectrum helps to achieve acceptable breeding without protactinium isolation.

Hundreds of solar water pumping stations in Sudan fulfill a similar role, involving various applications of different systems for pumping and storage. Over the past 10 years approximately. 250 photovoltaic water pumps have been installed in Sudan. Considerable progress has been made and the present generation of systems appear to be reliable and cost–effective under certain conditions. A photovoltaic pumping system to pump 25 cubic metres per day requires a solar array of approx. 800 Wp. Such a pump would cost US$6000, since the total system comprises the cost of modules, pump, motor, pipework, wiring, control system and array support structure. PV water pumping has been promoted successfully in Kordofan state in Sudan. It shows favorable economics as compared to diesel pumps, and is free from the need to maintain a regular supply of fuel. The only maintenance problems with PV pumping [are] due to the breakdown of pumps and not the failure of the PV devices.

The ISCC–NBS System of Color Designation is a system for naming colors based on a set of 13 basic color terms and a small set of adjective modifiers. It was first established in the 1930s by a joint effort of the Inter-Society Color Council (ISCC), made up of delegates from various American trade organizations, and the National Bureau of Standards (NBS), a US government agency. As suggested in 1932 by the first chairman of the ISCC, the system’s goal is to be "a means of designating colors in the United States Pharmacopoeia, in the National Formulary, and in general literature ... such designation to be sufficiently standardized as to be acceptable and usable by science, sufficiently broad to be appreciated and used by science, art, and industry, and sufficiently commonplace to be understood, at least in a general way, by the whole public." The system aims to provide a basis on which color definitions in fields from fashion and printing to botany and geology can be systematized and regularized, so that each industry need not invent its own incompatible color system.

He became a research associate professor at the University of Rochester where he stayed until 1965. The same year, he joined the University of Pennsylvania where he taught physics until 1966. Later, he went to Chicago, Illinois where he joined his brother Fayyazuddin, and theoretical physicists Faheem Hussain and Peter Rottoli. Riazuddin joined University of Chicago's Enrico Fermi Institute where they created the "Relativity Group". In 1968, Riazuddin returned to Pakistan on the request of Salam, and joined Quaid-i-Azam University's Institute of Physics. He was the founding director of the Institute of Physics (IP) where he engaged in research on string theory, the theory of relativity, particle physics and nuclear physics. Later, the scientists of the Relativity Group at the Enrico Fermi Institute returned to Pakistan on the request of Salam. In 1970, he returned to the United States where he became Professor of Mathematics at the University of Maryland. Riazuddin left the United States for Italy as he was asked by Salam to join the International Centre for Theoretical Physics in 1970. He was joined by other students of Salam where they created a Theoretical Physics Group at the ICTP. In 1971, Riazuddin traveled to the United Kingdom to join the Daresbury Nuclear Physics Laboratory where he was joined by Michael Duff. At Daresbury, he became senior research associate. There, Riazuddin gained expertise and specialised in nuclear physics. At Daresbury, he trained British scientists in the field of nuclear physics.

In a 2010 review Steve Henkel wrote, the "Dovekie is basically a decked-over open boat. Bolger's design is unusual (some would say radical) with a dead-flat bottom (no rocker, no deadrise), leeboards, a tiny bow centerboard for working to weather in shallows, and oar ports so she can be used without resorting to outboard power (though a side-mounted outboard bracket is a popular option). Best features: Dovekie feels like a big skiff under sail, and is fairly stable both underway and at anchor, especially considering her light, unballasted hull .. Worst features: Rowing power or a 2-hp outboard will only move her at about 2 to 3 knots. Accommodations are minimal, though no worse than her [competitors]. Be prepared to rough it."

Excavations were resumed at the Walcott Quarry by the Geological Survey of Canada under the persuasion of trilobite expert Harry Blackmore Whittington, and a new quarry, the Raymond, was established about 20 metres higher up Fossil Ridge. Whittington, with the help of research students Derek Briggs and Simon Conway Morris of the University of Cambridge, began a thorough reassessment of the Burgess Shale, and revealed that the fauna represented were much more diverse and unusual than Walcott had recognized. Many of the animals present had bizarre anatomical features and only the slightest resemblance to other known animals. Examples include "Opabinia", with five eyes and a snout like a vacuum cleaner hose and "Hallucigenia", which was originally reconstructed upside down, walking on bilaterally symmetrical spines.

Three years later, in 1924, Deguchi led a small group of Ōmoto-kyō disciples, including Ueshiba, on a journey to Mongolia at the invitation of retired naval captain Yutaro Yano and his associates within the ultra-nationalist Black Dragon Society. Deguchi's intent was to establish a new religious kingdom in Mongolia, and to this end he had distributed propaganda suggesting that he was the reincarnation of Genghis Khan. Allied with the Mongolian bandit Lu Zhankui, Deguchi's group were arrested in Tongliao by the Chinese authorities. Fortunately for Ueshiba, whilst Lu and his men were executed by firing squad, the Japanese group was released into the custody of the Japanese consul. They were returned under guard to Japan, where Deguchi was imprisoned for breaking the terms of his bail. During this expedition Ueshiba was given the Chinese alias Wang Shou-gao, rendered in Japanese as "Moritaka" – he was reportedly very taken with this name and continued to use it intermittently for the rest of his life.

His mother had a law degree, and after Dyson was born she worked as a social worker. Dyson had one sibling, his older sister, Alice, who remembered him as a boy surrounded by encyclopedias and always calculating on sheets of paper. At the age of four he tried to calculate the number of atoms in the Sun. As a child, he showed an interest in large numbers and in the solar system, and was strongly influenced by the book "Men of Mathematics" by Eric Temple Bell. Politically, Dyson said he was "brought up as a socialist".

The physics of the propagation of the baryon waves in the early universe is fairly simple; as a result cosmologists can predict the size of the sound horizon at the time of recombination. In addition the CMB provides a measurement of this scale to high accuracy. However, in the time between recombination and present day, the universe has been expanding. This expansion is well supported by observations and is one of the foundations of the Big Bang Model. In the late 1990s, observations of supernovae determined that not only is the universe expanding, it is expanding at an increasing rate. A better understanding of the acceleration of the universe, or dark energy, has become one of the most important questions in cosmology today. In order to understand the nature of the dark energy, it is important to have a variety of ways of measuring the acceleration. BAO can add to the body of knowledge about this acceleration by comparing observations of the sound horizon today (using clustering of galaxies) to that of the sound horizon at the time of recombination (using the CMB). Thus BAO provides a measuring stick with which to better understand the nature of the acceleration, completely independent from the supernova technique.

New York State has an AEMT-CC (advanced EMT - critical care) certification, which is unique to New York, and is more advanced than a nationally recognized AEMT. In addition to the national scope of practice, New York also authorizes its AEMT-CCs to intubate patients and do three lead ecg monitoring as well as twelve lead in certain counties, in addition to providing certain cardiac medications and cardiac care, including cardioversion. In more recent years, New York has expanded its AEMT-CC level to include the administration of certain narcotics and some additional skills. In order to transition to the national standard, NYS has introduced an additional AEMT certification that meets national standard as of 2013. It still must be recognized by its regional EMS councils in order for those regions to begin implementing its use. However, progress has been steady, with the most recent county to accept the new level of certification being Nassau County (located on Long Island). Nassau recognized this level in mid-2017. In 2018, NYS began a 10-year phase-out of its unique AEMT-CC level of certification. However, no advanced EMT certifications are recognized in New York City except at volunteer agencies such as Hatzalah EMS and Central Park Ambulance. One either functions as an EMT-B or a paramedic within FDNY and affiliated services.

Attempts have been made to market violins with machine tuners, but they have not been generally adopted primarily because earlier designs required irreversible physical modification of the pegbox, making violinists reluctant to fit them to classical instruments, and they added weight at the scroll. Early examples included large geared pegs that required much larger holes and/or bracing bars and additional holes, and tuning machines resembling those on a double bass, with metal plates screwed to the sides of the pegbox. Recent advances in machining technology have allowed the creation of several types of internally geared pegs the same size as the usual wooden pegs, requiring no more modification than would be seen in any peg replacement.

The Canadian Transportation Safety Board (CTSB) determined a failure of Crew Resource Management was largely responsible for the crash of First Air Flight 6560, a Boeing 737-200, in Resolute, Nunavut, on August 20, 2011. A malfunctioning compass gave the crew an incorrect heading, although the instrument landing system and Global Positioning System indicated they were off course. The first officer made several attempts to indicate the problem to the captain but a failure to follow airline procedures and a lack of a standardized communication protocol to indicate a problem led to the captain dismissing the first officer's warnings. Both pilots were also overburdened with making preparations to land, resulting in neither being able to pay full attention to what was happening.

The American system of manufacturing was a set of manufacturing methods that evolved in the 19th century. The two notable features were the extensive use of interchangeable parts and mechanization for production, which resulted in more efficient use of labor compared to hand methods. The system was also known as armory practice because it was first fully developed in armories, namely, the United States Armories at Springfield in Massachusetts and Harpers Ferry in Virginia (later West Virginia), inside contractors to supply the United States Armed Forces, and various private armories. The name "American system" came not from any aspect of the system that is unique to the American national character, but simply from the fact that for a time in the 19th century it was strongly associated with the American companies who first successfully implemented it, and how their methods contrasted (at that time) with those of British and continental European companies. In the 1850s, the "American system" was contrasted to the British factory system which had evolved over the previous century. Within a few decades, manufacturing technology had evolved further, and the ideas behind the "American" system were in use worldwide. Therefore, in manufacturing today, which is global in the scope of its methods, there is no longer any such distinction.

Acceptance and commitment therapy is probably the most well-researched of all the third-generation behavior therapy models. Its development co-occurred with that of relational frame theory, with several researchers such as Steven C Hayes being involved with both. ACT has been argued to be based on relational frame theory. Although this is a matter of some debate within the community, Originally, this approach was referred to as comprehensive distancing. Every practitioner mixes acceptance with a commitment to one's values. These ingredients become enmeshed into the treatment in different ways which leads to ACT being either more on the mindfulness side, or more on the behavior-changing side. ACT has, as of May 2022, been evaluated in over 900 randomized clinical trials for a variety of client problems. Overall, when compared to other active treatments designed or known to be helpful, the effect size for ACT is a Cohen's d of around 0.6, which is considered a medium effect size.

The accounts of Polybius leading up to the Battle of Telamon, c. 225 BC mention chariot warfare, but it was ultimately unsuccessful. The Gauls met comprehensive defeat by the Roman legions under Papus and Regulus. Chariot forces also attacked the legions as they were disembarking from ships during Caesar's invasion of Britain, but the Roman commander drove off the fast-moving assailants using covering fire (slings, arrows and engines of war) from his ships and reinforcing his shore party of infantry to charge and drive off the attack. In the open field against Caesar, the Gallic/Celtics apparently deployed chariots with a driver and an infantry fighter armed with javelins. During the clash, the chariots would drop off their warriors to attack the enemy and retire a short distance away, massed in reserve. From this position, they could retrieve the assault troops if the engagement was going badly, or apparently, pick them up and deploy elsewhere. Caesar's troops were discomfited by one such attack, and he met it by withdrawing into his fortified redoubt. A later Gallic attack against the Roman camp was routed.

As a result of this incident, rather than bringing legal action against McDonald's, Mann teamed up with the IEEE (world's largest technical society), the ACLU, and some industry leaders such as the Pete Wassell, CEO of Augmate Corporation, to propose the Mann-Wassell law for presentation to the New York legislature, as well an IEEE conference on the topic of Veillance. The goal of this work is to create a legal, policy, and social climate to counteract the actions of companies like McDonald's, that are likely to have a chilling effect on the research and use of Augmediated Reality technologies in everyday life. In this context, Mann also formalized the concept of McVeillance as placing people under surveillance while simultaneously forbidding them from using their own cameras. More precisely, McVeillance was defined as the ratio (linearly) or difference (logarithmically) of surveillance to sousveillance. McVeillance is one of the topics of the IEEE conference.

A 2015 re-evaluation of the DNA evidence states that "X2a has not been found anywhere in Eurasia, and phylogeography gives us no compelling reason to think it is more likely to come from Europe than from Siberia. Furthermore, analysis of the complete genome of Kennewick Man, who belongs to the most basal lineage of X2a yet identified, gives no indication of recent European ancestry and moves the location of the deepest branch of X2a to the West Coast, consistent with X2a belonging to the same ancestral population as the other founder mitochondrial haplogroups. Nor have any high-resolution studies of genome-wide data from Native American populations yielded any evidence of Pleistocene European ancestry or trans-Atlantic gene flow."

A fixed-aisle AS/R machine (stacker crane) is one of two main designs: single-masted or double masted. Most are supported on a track and ceiling guided at the top by guide rails or channels to ensure accurate vertical alignment, although some are suspended from the ceiling. The 'shuttles' that make up the system travel between fixed storage shelves to deposit or retrieve a requested load (ranging from a single book in a library system to a several ton pallet of goods in a warehouse system). The entire unit moves horizontally within an aisle, while the shuttles are able to elevate up to the necessary height to reach the load, and can extend and retract to store or retrieve loads that are several positions deep in the shelving. A semi-automated system can be achieved by utilizing only specialized shuttles within an existing rack system.

On the USOS, Whipple Shields are used. The US segment modules consist of an inner layer made from aluminium, a intermediate layers of Kevlar and Nextel (a ceramic fabric), and an outer layer of stainless steel, which causes objects to shatter into a cloud before hitting the hull, thereby spreading the energy of impact. On the ROS, a carbon fibre reinforced polymer honeycomb screen is spaced from the hull, an aluminium honeycomb screen is spaced from that, with a screen-vacuum thermal insulation covering, and glass cloth over the top.

In 1823 Jan Evangelista Purkyně identified nine fingerprint patterns. The nine patterns include the tented arch, the loop, and the whorl, which in modern-day forensics are considered ridge details. In 1840, following the murder of Lord William Russell, a provincial doctor, Robert Blake Overton, wrote to Scotland Yard suggesting checking for fingerprints. In 1853 the German anatomist Georg von Meissner (1829–1905) studied friction ridges, and in 1858 Sir William James Herschel initiated fingerprinting in India. In 1877 he first instituted the use of fingerprints on contracts and deeds to prevent the repudiation of signatures in Hooghly near Kolkata and he registered government pensioners' fingerprints to prevent the collection of money by relatives after a pensioner's death.

The discovery of a hitherto unsuspected extinct group of large marine reptiles generated much publicity, capturing the imagination of both scientists and the public at large. People were fascinated by the strange build of the animals, especially the large scleral rings in the eye sockets, of which it was sometimes erroneously assumed these would have been visible on the living animal. Their bizarre form induced a feeling of alienation, allowing people to realise the immense span of time passed since the era in which the ichthyosaur swam the oceans. Not all were convinced that ichthyosaurs had gone extinct: Reverend George Young found a skeleton in 1819 at Whitby; in his 1821 description, he expressed the hope that living specimens could still be found. Geologist Charles Lyell to the contrary, assumed that the Earth was eternal so that in the course of time the ichthyosaur might likely reappear, a possibility lampooned in a famous caricature by De la Beche.

While Galileo's application of mathematics to experimental physics was innovative, his mathematical methods were the standard ones of the day, including dozens of examples of an inverse proportion square root method passed down from Fibonacci and Archimedes. The analysis and proofs relied heavily on the Eudoxian theory of proportion, as set forth in the fifth book of Euclid's Elements. This theory had become available only a century before, thanks to accurate translations by Tartaglia and others; but by the end of Galileo's life, it was being superseded by the algebraic methods of Descartes. The concept now named Galileo's paradox was not original with him. His proposed solution, that infinite numbers cannot be compared, is no longer considered useful.

The pseudopotential is an effective potential constructed to replace the atomic all-electron potential (full-potential) such that core states are eliminated "and" the valence electrons are described by pseudo-wavefunctions with significantly fewer nodes. This allows the pseudo-wavefunctions to be described with far fewer Fourier modes, thus making plane-wave basis sets practical to use. In this approach usually only the chemically active valence electrons are dealt with explicitly, while the core electrons are 'frozen', being considered together with the nuclei as rigid non-polarizable ion cores. It is possible to self-consistently update the pseudopotential with the chemical environment that it is embedded in, having the effect of relaxing the frozen core approximation, although this is rarely done. In codes using local basis functions, like Gaussian, often effective core potentials are used that only freeze the core electrons.

AMCs have also showed promise in craniofacial bone regeneration. In 2014, George K. Sándor performed a small size clinical trial (n = 13) on patients with craniomaxillofacial defects where AMCs were transplanted with scaffolds of either bioactive glass or β-tricalcium phosphate in an attempt to reconstruct the defect. β-tricalcium phosphate scaffolds are characterized by their porous three-dimensional synthetic scaffold structures that stimulate growth, migration, and differentiation in human cells leading to bone reparation. This study saw 10 out of the 13 patients successfully integrate the AMCs and scaffolds. In 2017, the National Institute of Dental and Craniofacial Research (NIDCR) awarded $24 million to two centers focused on craniofacial disease and injury research.

In response, the U.S. Centers for Disease Control and Prevention and other agencies and organizations have issued guidance regarding workplace hazard controls for COVID-19. Some specific recommendations include modified call queries, symptom screening, universal PPE use, hand hygiene, physical distancing, and stringent disinfection protocols. Research on ambulance ventilation systems found that aerosols often recirculate throughout the compartment, creating a health hazard for EMTs when transporting sick patients capable of airborne transmission. Unidirectional airflow design can better protect workers.

It is found from the Mexican states of Nuevo León (25° N. Lat.) and Jalisco (22° n.l.) to the north and to Nicaragua (15° N. Lat.) to the south. It occurs on both mountain ranges of the Sierra Madre Oriental and Sierra Madre Occidental. It grows at altitudes from 2000–3200 m above sea level. It is found in areas between 800–1000 mm rainfall per year. In most of the tree's habitat, rain falls mostly in summer, but in the state of Veracruz, precipitations are spread year round and the climate is very wet. However, specimens from the state of Jalisco grow in semi-arid places. It occurs in warm temperate to cool climates (18 °C to 10 °C). At the highest altitudes of its distribution it usually receives snow in the winter.

Headwater streams play a major role in the physicochemical quality of larger rivers and streams because of their close association to the surrounding landscape. They function to retain floodwaters, store nutrients and reduce sediment accumulation. VF processes limit these functions, negatively impacting surrounding rivers and watersheds. Factors contributing to disturbed stream flow include vegetation removal, subsequent aquifer formation, compaction of fill surface and overall loss of headwater streams. The removal of vegetation for mining sites reduces evapotranspiration rates from the watershed and ultimately leads to an increase in average discharge rates. Changes in flow can also be attributed to the formation of aquifers from VF that can store water entering from groundwater sources, surface run-off and precipitation. Compaction of VF sites from MTM equipment can increase the surface run-off contribution. The overall loss of headwater streams from VF practices reduces surface- groundwater connections.
