The thymus increases in size from birth in response to postnatal antigen stimulation. It is most active during the neonatal and pre-adolescent periods. The thymus is located between the inferior neck and the superior thorax. At puberty, by the early teens, the thymus begins to atrophy and regress, with adipose tissue mostly replacing the thymic stroma. However, residual T cell lymphopoiesis continues throughout adult life, providing some immune response. The thymus is where the T lymphocytes mature and become immunocompetent. The loss or lack of the thymus results in severe immunodeficiency and subsequent high susceptibility to infection. In most species, the thymus consists of lobules divided by septa which are made up of epithelium which is often considered an epithelial organ. T cells mature from thymocytes, proliferate, and undergo a selection process in the thymic cortex before entering the medulla to interact with epithelial cells.

On 25 June 2013, Davis went to the American Institute in Taiwan, the "de facto" U.S. embassy, to renounce his citizenship. The AIT processed his case much more quickly than would have been done under normal procedures, and he received his Certificate of Loss of Nationality three days later, temporarily making him a stateless person. There remained doubts whether the Ministry of the Interior could complete all the procedures relating to his naturalization by the 12 July deadline for him to register for the 2013 FIBA Asia Championship, but in the end he was officially naturalized as a citizen of the Republic of China on 9 July. Taiwanese American players such as Richard Chang had previously joined the Chinese Taipei team, but Davis was the first American of another ethnic background to follow in their footsteps. Unlike most male citizens both naturalized and native-born Davis was not be required to serve in the Republic of China Armed Forces because men over tall are exempt from conscription in Taiwan.

To provide this atmosphere, 3.5×10 kilograms of water could be delivered by a similar process as proposed for Venus by launching a stream of kinetic impactors at Hyperion (the moon of Saturn) causing it to be ejected and flung into the inner solar system. Once this water has been delivered, Mercury could be covered in a thin layer of doped titanium dioxide photo-catalyst dust which would split the water into its constituent oxygen and hydrogen molecules, with the hydrogen rapidly being lost to space and a 0.2-0.3 bar atmosphere of pure oxygen being left behind in less than 70 years (assuming an efficiency of 30-40%). At this point the atmosphere would be breathable and nitrogen may be added as required to allow for plant growth in the presence of nitrates.

In February 2019, fifty mummy collections wrapped in linen, stone coffins or wooden sarcophagi dated back to the Ptolemaic Kingdom were discovered by Egyptian archaeologists in the Tuna El-Gebel site in Minya. 12 of the graves in four burial chambers 9 m (30 ft) deep, belonged to children. One of the remains was the partly uncovered skull enclosed in linen. Egypt’s Minister of Tourism and Antiquities announced the discovery of the collective graves of senior officials and high clergies of the god Djehuty (Thoth) in Tuna el-Gebel in January, 2020. An archaeological mission headed by Mustafa Waziri reported that 20 sarcophagi and coffins of various shapes and sizes, including five sarcophagi made of limestone and carved with hieroglyphic texts, as well as 16 tombs and five well-preserved wooden coffins were unearthed by their team.

From the 1960s onward there was a growing demand for greater consideration of community opinions in major decision-making. In Australia many people believed that they were not being planned 'for' but planned 'at'. (Nichols 2009). A lack of consultation made the planning system seem paternalistic and without proper consideration of how changes to the built environment affected its primary users. In Britain "the idea that the public should participate was first raised in 1965" (Taylor, 1998, p. 86). However the level of participation is an important issue. At a minimum public workshops and hearings have now been included in almost every planning endeavour. Yet this level of consultation can simply mean information about change without detailed participation. Involvement that 'recognises an active part in plan making' (Taylor, 1998, p. 86) has not always been straightforward to achieve. Participatory design has attempted to create a platform for active participation in the design process, for end users.

Natural selection normally favors a gene if it increases reproduction, because the offspring share copies of that gene. However, a gene can also be favored if it aids other relatives, who also share copies. Therefore, by helping a close relative reproduce, an individual is still passing on its own genes to the next generation, albeit indirectly. Hamilton pointed out that kin selection could occur via two mechanisms: (a) kin discrimination, when cooperation is preferentially directed toward relatives, and (b) limited dispersal (population viscosity), which keeps relatives in spatial proximity to one another, allowing cooperation to be directed indiscriminately toward all neighbors (who tend to be relatives). In microbial systems, these two mechanisms are equally important. For example, most microbial populations often begin from a small number of colonizers. Because most microbes reproduce asexually, close genetic relatives will surround cells as the population grows. These clonal populations often result in an extremely high density, especially in terrestrial systems. Therefore, the probability that a cells altruistic behavior will benefit a close relative is extremely high.

After D. O. Mills died in 1910, his son, Ogden Mills, agreed to fund the site until 1913. A sum totaling $30,000 was provided, covering expenses up through 1914. In addition to normal measurements, Campbell decided to use the additional time to make spectrographic measurements of nebulae in the southern hemisphere. These would supplement the previous measurement of thirteen nebulae made by James E. Keeler in the northern hemisphere. Observations of twelve nebulae in the Greater Magellanic Cloud indicated that this formation was receding with a velocity of , which suggested that it may be an related to the spiral nebulae. After four years in charge, Moore returned to California in 1913, being replaced by Ralph E. Wilson as of August 1, the same year. Sanford remained behind for two more years, departing in June 1915.

Centuries later, Euclid's algorithm was discovered independently both in India and in China, primarily to solve Diophantine equations that arose in astronomy and making accurate calendars. In the late 5th century, the Indian mathematician and astronomer Aryabhata described the algorithm as the "pulverizer", perhaps because of its effectiveness in solving Diophantine equations. Although a special case of the Chinese remainder theorem had already been described in the Chinese book "Sunzi Suanjing", the general solution was published by Qin Jiushao in his 1247 book "Shushu Jiuzhang" (數書九章 "Mathematical Treatise in Nine Sections"). The Euclidean algorithm was first described "numerically" and popularized in Europe in the second edition of Bachet's "Problèmes plaisants et délectables" ("Pleasant and enjoyable problems", 1624). In Europe, it was likewise used to solve Diophantine equations and in developing continued fractions. The extended Euclidean algorithm was published by the English mathematician Nicholas Saunderson, who attributed it to Roger Cotes as a method for computing continued fractions efficiently.

Collaboration, consultation, and repatriation are key components of decolonizing museums. Australian museums have been leaders in developing repatriation processes, consultation, and collaboration with Indigenous communities, beginning in the late 1980s. Projects involving collaboration and consultation with source communities have taken many forms, ranging from developing traveling exhibits, revising collection catalogues, to establishing community cultural centers and working with photographic collections together. In Canada, collaboration and consultation were first formally suggested by the 1994 Task Force Report on Museums and First Peoples, and are now seen by many museums as being an essential practice for any institution that holds collections belonging to Indigenous peoples. In North America, and around the world, some of the objects in those collections – particularly sacred objects or human remains – have been repatriated or returned to their communities of origin. The Native American Graves Protection and Repatriation Act (1990) formalized the process of repatriating Indigenous cultural objects in the United States. While Canada does not have a formal policy around repatriation, many museums have their own internal policies and many objects have been returned to Indigenous communities that way. Though repatriation policies are typically well intended, the process has often been complicated by institutional, community, and government politics, and have had varying degrees of success.

Under the Lyndon B. Johnson administration, which gained power after the assassination of John F. Kennedy, the US took a more hardline stance on Latin America—sometimes called the "Mann Doctrine". In 1964, the Brazilian military overthrew the government of president João Goulart with US backing. In late April 1965, the US sent some 22,000 troops to the Dominican Republic in an intervention, codenamed Operation Power Pack, into the Dominican Civil War between supporters of deposed president Juan Bosch and supporters of General Elías Wessin y Wessin, citing the threat of the emergence of a Cuban-style revolution in Latin America. The OAS also deployed soldiers to the conflict through the mostly Brazilian Inter-American Peace Force. Héctor García-Godoy acted as provisional president, until conservative former president Joaquín Balaguer won the 1966 presidential election against non-campaigning Juan Bosch. Activists for Bosch's Dominican Revolutionary Party were violently harassed by the Dominican police and armed forces.

The pelvis joint has the usual ball-and-socket joint configuration. The somewhat flattened femoral head could theoretically have fit into the hip socket at a wide range of angles. In 1982, palaeontologist Tom S. Kemp suggested that early theriodonts, including gorgonopsians, could place the femur at both a horizontal angle in a sprawling gait, as well as a more vertical angle in an erect gait. He compared the locomotory habits of these creatures to those of crocodilians, which utilise a sprawling gait over short distances, but switch to an erect one while running or moving over longer distances. Though the hip of "Sauroctonus" seems to be anatomically intermediate between "Dimetrodon" and mammals—with the ilium expanded more in the headwards direction than the tailwards, and the pubis somewhat reduced—the puboischiofemoralis muscle (a large muscle carried only by reptiles which runs from the pelvis to the femur) extensively attached to the underside of the pubis and ischium, which would have allowed it to produce a strong adducting force (drawing the legs closer to the body), useful in a sprawling gait. It is also conceivable that gorgonopsians primarily engaged this muscle while grappling struggling prey. The shins are relatively short compared to the femur, which suggests gorgonopsians were not well adapted for running long distances.

After all tests were complete, the SA-500D was reassembled in Huntsville, this time for public exhibition at the Alabama Space Science Center, on land carved out of the north edge of Marshall Space Flight Center. Transport of the rocket, along with the Saturn I which would be erected vertically, to the museum, took place June 28, 1969. The rocket would be displayed lying down on the southern edge of a rocket park with its predecessor rockets, near a Saturn 1 standing erect and a moonscape complete with model lunar module and a flag. SA-500D was installed in 1969, and the (renamed) Alabama Space and Rocket Center opened in 1970 showcasing articles that could otherwise only be seen by NASA and Army workers at Redstone Arsenal. The first stage sat on a low-boy trailer and the others in cradles. The instrument unit was put on display inside the museum, and interstages were given roofs and converted to educational rides for the museum.

Wood uses historically were determined by its particular characteristics, e.g., 0.43 mean specific gravity nearly equal to Douglas-fir (Pseudotsuga menziesii); strength properties similar to ponderosa pine; Kraft pulps high in bursting with tensile strength comparable to some northern conifer pulps; and foothill stands loggable in winter, when higher-altitude species were inaccessible. However, the high amounts of resin and compression wood, the often crooked form, heavy weight, and low stand density, made it expensive otherwise to log, transport and process. Commercial value decreased by the 1960s, to limited use for railroad ties, box "shook", pallet stock, and chips.

During the 1920s, French astronomer Bernard Lyot used a polarimeter to study the surface properties of the Moon and planets. In 1929, he noted that the polarized light emitted from the Martian surface is very similar to that radiated from the Moon, although he speculated that his observations could be explained by frost and possibly vegetation. Based on the amount of sunlight scattered by the Martian atmosphere, he set an upper limit of 1/15 the thickness of the Earth's atmosphere. This restricted the surface pressure to no greater than . Using infrared spectrometry, in 1947 the Dutch-American astronomer Gerard Kuiper detected carbon dioxide in the Martian atmosphere. He was able to estimate that the amount of carbon dioxide over a given area of the surface is double that on the Earth. However, because he overestimated the surface pressure on Mars, Kuiper concluded erroneously that the ice caps could not be composed of frozen carbon dioxide. In 1948, American meteorologist Seymour L. Hess determined that the formation of the thin Martian clouds would only require of water precipitation and a vapor pressure of .

New uniforms were designed and made for the film "Star Trek Generations", but were abandoned at the last minute. These included a fastening on the right side of the chest and a slightly more militaristic approach with rank bandings on the sleeves (similar to the "TOS" uniforms) and a colored collar and the lack of a black "W" shape on the abdomen. The costumes for the female crew-members were different - instead of the additional fastening, there was a higher than previously seen black band around the waist. Nonetheless, Playmates Toys released a number of action figures wearing these planned uniforms. "Generations" instead has the crew wearing both "TNG" and "DS9" uniforms, sometimes in the same scene (for instance, Worf and Riker in the battle against the Duras Sisters' Bird of Prey or Data and Geordi scanning the Amargosa Observatory for trilithium) as Jonathan Frakes and LeVar Burton had to borrow Avery Brooks and Colm Meaney's costumes respectively since the time was so short while there was enough time to make "DS9"-style costumes to fit on Patrick Stewart and Brent Spiner, though neither of the costumes fit very well on both Frakes and Burton as Brooks' costume was too small on Frakes, which resulted in having the sleeves rolled up (similar to Miles O'Brien's on "Deep Space Nine") and Meaney's costume looked too big on Burton. Picard, Riker, Data and LaForge are the only four characters in the "TNG" crew to wear the "DS9" uniform in the film. However, Worf is the only male character in the "TNG" crew to not wear the "DS9" uniform in the film, although he would later join the "DS9" crew in the fourth season of "Deep Space Nine" and none of the female characters wear the "DS9" uniform in the film, although Alyssa Ogawa is the only female to wear the "DS9" uniform in the film. Strangely, Picard wears a black belt around the waist while wearing the "DS9" uniform.

The continuing search for Burgess Shale fossils since the mid-1970s has led to the description in the 1980s of an arthropod "Sanctacaris" and in 2007 of "Orthrozanclus", which looked like a slug with a small shell at the front, chain mail over the back and long, curved spines round the edges. Recent digs have discovered species yet to be formally described and named. They have also unearthed more and sometimes better fossils of animals that were discovered earlier, for example "Odontogriphus" was for many years known from just one poorly preserved specimen, but the discovery of a further 189 formed the basis for a detailed description and analysis in 2006. Re-examination of Walcott's collection also continues, and has led to the reconstruction of the large marine animal "Hurdia" in 2009.

The scientific community has been quick to harness RNA silencing as a research tool. The strategic targeting of mRNA can provide a large amount of information about gene function and its ability to be turned on and off. Induced RNA silencing can serve as a controlled method for suppressing gene expression. Since the machinery is conserved across most eukaryotes, these experiments scale well to a range of model organisms. In practice, expressing synthetic short hairpin RNAs can be used to reach stable knock-down. If promoters can be made to express these designer short hairpin RNAs, the result is often potent, stable, and controlled gene knock-down in both in vitro and in vivo contexts. Short hairpin RNA vector systems can be seen as roughly analogous in scope to using cDNA overexpression systems. Overall, synthetic and natural small RNAs have proven to be an important tool for studying gene function in cells as well as animals.

The E.28/39 was the product of a specification which had been issued by the Air Ministry for a suitable aircraft to test the novel jet propulsion designs that Frank Whittle had been developing during the 1930s. Gloster and the company's chief designer, George Carter, worked with Whittle to develop an otherwise conventional aircraft fitted with a Power Jets W.1 turbojet engine. Flying for the first time on 15 May 1941, two E.28/39 aircraft were produced for the flight test programme. Following initial satisfactory reports, these aircraft continued to be flown to test increasingly refined engine designs and new aerodynamic features. Despite the loss of the second prototype, due to improper maintenance causing a critical aileron failure, the E.28/39 was considered to be a success.

There are claimed to be over a million acres (4,000 km) of farmland worldwide using some kind of BCSR theory for balancing their soils, and the testimonies of farmers seem to back it up as a practical method. However, BCSR is almost always used by farmers transitioning to sustainable agriculture, hence the simultaneous use of other soil improvement methods (such as cover crops, reduced tillage, and addition of organic matter) makes it difficult to isolate the effects of the BCSR method. Many BCSR practitioners stress that the system cannot work when abstracted from a 'holistic' approach to farming. Though this complicates investigation, it does not invalidate the approach, since many other aspects of sustainable agriculture only work in concert with each other. For example, integrated pest management requires the use of polycultures, cover crops, reduction of pesticides and even agroforestry to a degree, and its efficacy will be greatly reduced if all these things are ignored.

The main structural differences between MPS and UNSNA are attributable to a different interpretation of newly created value, and of the accumulation of stocks of wealth. Consequently, there are differences in grossing and netting procedures for the main aggregates. In MPS, many services are not regarded as value-adding, and therefore excluded from the total net output. As the name suggests, the MPS aims to measure the annual output of "material goods", in contrast with services. In MPS the economy is divided up into three sectors: (1) productive enterprises, (2) the non-productive sphere, and (3) households. Typically the planning authorities also collected comprehensive data on the physical units of products produced. This is normally not the case in conventional national accounts, which measure only the momentary market value of outputs produced.

A study by Peigneux "et al.", (2004) noted that the firing sequences in the hippocampal ensembles during spatial learning are also active during sleep, which shows that post training sleep has a role in processing spatial memories. This study was done to prove that the same hippocampal areas are activated in humans during route learning in a virtual town, and are reactivated during subsequent slow wave sleep (SWS). In order to monitor this activation, experimenters used PET scans and fMRI to use cerebral blood flow as a marker of synaptic activity. The finding noted that the amount of hippocampal activation during slow-wave sleep positively correlated to the improvement on the virtual tour task the following day, which indicates that hippocampal activity during sleep correlates with the improvement in memory performance. These findings prove that learning-dependent modulation in hippocampal activity while sleeping shows processing of the previously learned episodic and spatial memory traces. This modulation of the hippocampus leads to plastic changes in the brain and ultimately an improvement in performance. The results of this study showed that spatial memory traces are processed in humans while they are in NREM sleep. It showed a reaction of the hippocampal formation during SWS, after a declarative spatial memory task. Experimenters also found, that in humans, there is experience-dependent modulation of activity during NREM sleep in the hippocampal regions, but not during REM sleep after learning. The evidence from this study was substantial to its hypothesis that the information learned while awake is altered, and strengthened while humans are sleeping.

Following Husserl, Merleau-Ponty attempts to reveal the phenomenological structure of perception. He writes that while the "notion of sensation ... seems immediate and obvious", it is in fact confused. Merleau-Ponty asserts that because "traditional analyses" have accepted it, they have "missed the phenomenon of perception." Merleau-Ponty argues that while sensation could be understood to mean "the way in which I am affected and the experiencing of a state of myself", there is nothing in experience corresponding to "pure sensation" or "an atom of feeling". He writes that, "The alleged self-evidence of sensation is not based on any testimony of consciousness, but on widely held prejudice." Merleau-Ponty's central thesis is that of the "primacy of perception." He critiques the Cartesian stance of ""cogito ergo sum"" and expounds a different conception of consciousness. Cartesian dualism of mind and body is called into question as the primary way of existing in the world, and is ultimately rejected in favor of an intersubjective conception or dialectical and intentional concept of consciousness. The body is central to Merleau-Ponty's account of perception. In his view, the ability to reflect comes from a pre-reflective ground that serves as the foundation for reflecting on actions.

Neurons in the CNS are organized as interconnected groups of functionally related cells (e.g., in sensory systems). A diffusible factor released from a neuron into the interstitial fluid, and able to interact with membrane receptors on adjacent cells, would be ideally used to "synchronize" the activity of an ensemble of interconnected neural cells. Furthermore, during development and in certain forms of learning, postsynaptic cells may secrete regulatory factors which diffuse back to the presynaptic component, determining its survival as an active terminal, the amplitude of its sprouting, and its efficacy in secreting neurotransmitters—a phenomenon known as retrograde regulation. The participation of arachidonic acid metabolites in retrograde signaling and in other forms of local modulation of neuronal activity has been proposed.

ASEE was a volunteer-run organization through the 1950s. In 1961, ASEE established a staff headquarters in Washington, DC, and undertook a more activist posture. However, through the 1960s, the Vietnam War and social unrest, in general, made the mood on many campuses anti-technology, anti-business, and anti-establishment. In the 1960s and 1970s, ASEE presidents Merritt Williams and George Hawkins reorganized ASEE to better represent its members and return its focus to teaching. As a result of this new focus, ASEE began to administer several teaching-related government contracts, including NASA's summer faculty fellowships and the Defense Department's Civil Defense Summer Institutes and Fellowships. Currently, ASEE administers over ten government contracts, including the prestigious National Science Foundation's Graduate Research Fellowship Program.

When Allied troops were halted near Anzio, Italy during the spring of 1944, powered personal radio receivers were strictly prohibited as the Germans had equipment that could detect the local oscillator signal of superheterodyne receivers. Crystal sets lack power driven local oscillators, hence they could not be detected. Some resourceful soldiers constructed "crystal" sets from discarded materials to listen to news and music. One type used a blue steel razor blade and a pencil lead for a detector. The lead point touching the semiconducting oxide coating (magnetite) on the blade formed a crude point-contact diode. By carefully adjusting the pencil lead on the surface of the blade, they could find spots capable of rectification. The sets were dubbed "foxhole radios" by the popular press, and they became part of the folklore of World War II.

As a result, both Umatarō and Hiroshi end up being targeted by a mysterious organization, as they get involved in the secrets of the underworld, the murkiness of the government, and the darkness of the catastrophe five years ago, but this does not damper their spirits. At the request of the Ministry of Science and the university's upper management, they are asked to participate in the World Robot Battling (WRB) event in Australia with the successor to A106, A107 (Yuran). However, as Yuran's enthusiasm for the competition spread, the other robots began to run amok. In the end, the WRB is cancelled, and when they return to Japan, Hiroshi's grandfather, who had been out of town, appeared before them. What he told them was an unbelievable story about a "boy-shaped robot from the future" (which Hiroshi had heard of before). Based on the information his grandfather had given him, Umatarō and Hiroshi headed for Ho Chi Minh City in Vietnam. There, they incompletely solve the mystery of the boy-shaped robot in question.

Many organic compounds such as acetate, butyrate, and lactate, largely exists in effluents of wastewater plants and fermentation units. These organics are valued products, but due to their low concentrations, extraction is not a cost-effective option. Therefore, MES has been employed for the conversion of these short-chain carboxylic acids to longer chain acids and other useful products. Although higher value compounds can be obtained from low resource cost feeds, studies are required to compare if controlling the redox potential and supplying current to cathodes is economically feasible in comparison to current technologies. Nevertheless, further improvements in this technology platform can help in overcoming many of the fundamental challenges of a future bioeconomy.

On March 28, 2014, the NHTSA announced that it had closed the investigation into whether the Model S design was making the electric car prone to catch fire, after the automaker said it would provide more protection to its lithium-ion batteries. According to the NHTSA, the titanium underbody shield and aluminum deflector plates, along with increased ground clearance, reduce the severity, frequency, and fire risk of underbody strikes. All Model S cars manufactured after March 6 have the aluminum shield over the battery pack replaced with a new three-layer shield designed to protect the battery and charging circuitry from being punctured even in very high speed impacts. The new shielding features a hollow aluminum tube to deflect impacting objects, a titanium shield to protect sensitive components from puncture damage, and an aluminum extrusion to absorb impact energy. The new shields, which decrease vehicle range by 0.1%, will be installed free-of-charge in existing Model S vehicles by request or during the next scheduled maintenance. According to the NHTSA, the titanium underbody shield and aluminum deflector plates, along with increased ground clearance, "should reduce both the frequency of underbody strikes and the resultant fire risk."

Former NASA chief historian Roger D. Launius wrote, "More than any other incident in the history of spaceflight, recovery from this accident solidified the world's belief in NASA's capabilities". Nevertheless, the accident convinced some officials, such as Manned Spaceflight Center director Gilruth, that if NASA kept sending astronauts on Apollo missions, some would inevitably be killed, and they called for as quick an end as possible to the program. Nixon's advisers recommended canceling the remaining lunar missions, saying that a disaster in space would cost him political capital. Budget cuts made such a decision easier, and during the pause after Apollo 13, two missions were canceled, meaning that the program ended with Apollo 17 in December 1972.

, the EU-supported project "CiteairII" argued that the CAQI had been evaluated on a "large set" of data, and described the CAQI's motivation and definition. "CiteairII" stated that having an air quality index that would be easy to present to the general public was a major motivation, leaving aside the more complex question of a health-based index, which would require, for example, effects of combined levels of different pollutants. The main aim of the CAQI was to have an index that would encourage wide comparison across the EU, without replacing local indices. "CiteairII" stated that the "main goal of the CAQI is not to warn people for possible adverse health effects of poor air quality but to attract their attention to urban air pollution and its main source (traffic) and help them decrease their exposure."

Coming to the throne at the age of 16, Gustavus Adolphus inherited three wars from his father Charles IX of Sweden; border conflicts with Russia and Denmark-Norway, and a dynastic struggle with his first cousin, King Sigismund III Vasa of Poland. Of these, the Danish war was the most serious. During his reign, Sweden rose from the status of a Baltic Sea basin regional power to one of the great powers of Europe and a model of early modern era government. Gustavus Adolphus is known as the "father of modern warfare", or the first modern general. He taught a number of other military commanders, such as Lennart Torstensson, who would go on to expand the boundaries and the power of Swedish Empire after Gustavus Adolphus's death. Spoils meant he became a successful bookraider in Europe, targeting Jesuit collections.

The second ICWES conference was organised by the United Kingdom's Women's Engineering Society (WES) and took place in Cambridge, England in 1967. The themes of the conference were the application of technology to solve world food problems and the question of women's representation in engineering and science across the world. There were 309 listed attendees from 35 different countries, with attendees including Ghanaian zoologist Leticia Obeng, Ugandan engineer Miriam Muwanga, Japanese geochemist Katsuko Saruhashi, American aeronautical engineer Katherine Stinson, Betty Lou Bailey who worked for General Electric Company and engineer and journalist Elsie Eaves and Indian mechanical engineer Ila Ghose and K. K. Khubchandani. Nigerian physicists Deborah Ajakaiye and Ebun Adegbohungbe also attended. In "The Woman Engineer" – journal of WES – Leticia Obeng commented on the atmosphere of the conference: 'The change from the serious talks in the Chemistry Laboratory Hall to the gay atmosphere at the pre-banquet reception was a vivid demonstration of the adaptability of the human female to varying conditions.' British attendees included engineers Isabel Hardwich, Ira Rischowski, Rose Winslade, Cicely Thompson, and Hettie Bussell.

Crean's initial naval apprenticeship was aboard the training ship "Impregnable" at Devonport. In November 1894, he was transferred to "Devastation". In December 1894, Crean was posted to HMS Wild Swan a screw sloop as the ship headed to South America to join the Pacific Station. In 1895, Crean was serving in the Americas aboard Royal Arthur, the flagship assigned to the Pacific squadron's base at Esquimalt in Canada. He was by this time, rated an ordinary seaman. Less than a year later, while serving a second term of service aboard Wild Swan he was rated an able seaman. He later joined the Navy's torpedo school ship, "Defiance". By 1899, Crean had advanced to the rate of petty officer, second class and was serving in "Vivid". In 1900, Crean was ledgered to the cruiser "HMS" "Ringarooma", which was part of the Royal Navy's  Australian Squadron based in  Sydney. On 18 December 1901, he was demoted from petty officer to able seaman for an unspecified misdemeanour. In December 1901, the "Ringarooma" was ordered to assist Robert Falcon Scott's ship "Discovery" when it was docked at Lyttelton Harbour awaiting to departure to Antarctica. When an able seaman of Scott's ship deserted after striking a petty officer, a replacement was required; Crean volunteered, and was accepted.

The differences between OPM and UML are highly perceivable during the analysis and design stages. While UML is a multi-model, OPM supports a single unifying structure-behavior model. The crucial differences stem from the structure-oriented approach of UML, in which behavior is spread over thirteen diagram types, a fact that inevitably invokes the model multiplicity problem. First, using the OPM approach enables to view at main diagram (SD) the main process, objects and the connection between them. In addition, it is easy to understand what is the main system's benefit (presented at the SD). In OPM, it's also easier to understand the main three aspects of the system: behavior, structure and functionality (contrary to UML which describes these aspects with different types of diagrams). Database unfolding modeling contributes to the understanding of system and all details which is stored in the system. In addition, creating in-zooming enables simplifying the model. OPM requires extensive knowledge of systematic processes such as how the system saved the path and gets decisions.

Robotnik/Eggman appears in the theatrical "Sonic the Hedgehog" film released by Paramount Pictures in 2020, with Jim Carrey portraying a live-action version of the character. In the film, he is referred to almost exclusively as Robotnik, and is depicted as a twisted scientist hired by the United States Department of Defense to hunt down Sonic after he caused a power outage across the Pacific Northwest. Eventually, he receives the moniker "Eggman" from Sonic after the egg-shaped designs of his robots. Robotnik uses one of Sonic's quills to power up his machines to match Sonic's speed, but is eventually defeated by Sonic. He is transported to a planet filled with mushrooms, and after being trapped there for 87 days, he shaves his head and grows out his moustache, making him further resemble his in-game appearances, as he plots his revenge against Sonic.

Stylidium ericksoniae (initially described by J. H. Willis in 1956 as "Stylidium ericksonae") is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae). It is an annual plant that grows from 6 to 15 cm tall. The linear or deltate leaves, about 20-100 per plant, are mostly in terminal rosettes but with some scattered along the elongate stem. The leaves are generally long and wide. Petioles are absent. This species produces 1–20 scapes per plant. Inflorescences are long and produces a single pink or mauve flower that blooms from March to August in the southern hemisphere. "S. ericksoniae" is endemic to the northern areas of the Northern Territory of Australia. Its habitat is recorded as being damp sand near sandstone rocks or on swampy drainage channels. It's been found in association with "Micraira" and "Pandanus" species. "S. ericksoniae" is most closely associated with "S. pedunculatum". Its conservation status has been assessed as data deficient.

Ashley was born in Bermondsey, South London on 25 February 1860. The marginal life of his early years was shaped by the underemployment of his father, a journeyman hatter; his scepticism of free trade economics may have originated from his observations during his formative years. He was educated at St Olave's Grammar School and then at Balliol College, Oxford. He escaped the near-choiceless world of his youth through academic brilliance and, ultimately, by winning the 1878 Brackenbury history scholarship to Balliol College, which was then pursuing social uplift policies under the mastership of the legendary Benjamin Jowett. At Oxford he was influenced by Jowett, Bishop William Stubbs, and especially by the economic historian, Arnold Toynbee. In 1882, he won the Lothian Prize Essay competition. After Oxford, he studied at Heidelberg University, where he was influenced by the well-developed studies of economic history is developed by Schmoller and Karl Knies.

Recent studies have found a relationship between hydraulic roughness and salmon spawning habitat; “bed-surface grain size is responsive to hydraulic roughness caused by bank irregularities, bars, and wood debris… We find that wood debris plays an important role at our study sites, not only providing hydraulic roughness but also influencing pool spacing, frequency of textural patches, and the amplitude and wavelength of bank and bar topography and their consequent roughness. Channels with progressively greater hydraulic roughness have systematically finer bed surfaces, presumably due to reduced bed shear stress, resulting in lower channel competence and diminished bed load transport capacity, both of which promote textural fining”. Textural fining of stream beds can effect more than just salmon spawning habitats, “bar and wood roughness create a greater variety of textural patches, offering a range of aquatic habitats that may promote biologic diversity or be of use to specific animals at different life stages.”

The Netherlandish artists moved away from the profile view – popularised during the Italian Quattrocento – towards the less formal but more engaging three-quarter view. At this angle, more than one side of the face is visible as the sitter's body is rotated towards the viewer. This pose gives a better view of the shape and features of the head and allows the sitter to look out towards the viewer. The gaze of the sitter rarely engages the viewer. Van Eyck's 1433 "Portrait of a Man" is an early example, which shows the artist himself looking at the viewer. Although there is often direct eye contact between subject and viewer, the look is normally detached, aloof and uncommunicative, perhaps to reflect the subject's high social position. There are exceptions, typically in bridal portraits or in the case of potential betrothals, when the object of the work is to make the sitter as attractive as possible. In these cases the sitter was often shown smiling, with an engaging and radiant expression designed to appeal to her intended.

Other countries soon saw the advantage of camouflage, and established their own units of artists, designers and architects. The British established a Camouflage Section in late 1916 at Wimereux, and the U.S. followed suit with the New York Camouflage Society in April 1917, the official Company A of 40th Engineers in January 1918 and the Women's Reserve Camouflage Corps. The Italians set up the "Laboratorio di mascheramento" in 1917. By 1918 de Scévola was in command of camouflage workshops with over 9,000 workers, not counting the "camoufleurs" working at the front itself. Norman Wilkinson who first proposed dazzle camouflage to the British military employed 5 male designers and 11 women artists, who by the end of the war had painted more than 2,300 vessels. French women were employed behind the lines of both the British and American armies, sewing netting to disguise equipment and designing apparel for soldiers to wear.

Engineered zinc finger arrays are often fused to a DNA cleavage domain (usually the cleavage domain of FokI) to generate zinc finger nucleases. Such zinc finger-FokI fusions have become useful reagents for manipulating genomes of many higher organisms including "Drosophila melanogaster", "Caenorhabditis elegans", tobacco, corn, zebrafish, various types of mammalian cells, and rats. Targeting a double-strand break to a desired genomic locus can be used to introduce frame-shift mutations into the coding sequence of a gene due to the error-prone nature of the non-homologous DNA repair pathway. If a homologous DNA "donor sequence" is also used then the genomic locus can be converted to a defined sequence via the homology directed repair pathway. An ongoing clinical trial is evaluating Zinc finger nucleases that disrupt the CCR5 gene in CD4 human T-cells as a potential treatment for HIV/AIDS.

NASA Launch Services Program (LSP) investigators have determined the technical root cause for the Taurus XL launch failures of NASA's Orbiting Carbon Observatory (OCO) and Glory missions in 2009 and 2011, respectively: faulty materials provided by aluminium manufacturer, Sapa Profiles, Inc. (SPI). LSP's technical investigation led to the involvement of NASA's Office of the Inspector General and the U.S. Department of Justice (DOJ). The efforts of the DOJ, recently made public, resulted in the resolution of criminal charges and alleged civil claims against SPI, and its agreement to pay $46 million to the U.S. government and other commercial customers. This relates to a 19-year scheme that included falsifying thousands of certifications for aluminium extrusions to hundreds of customers.

The unique decoding model in coding theory, which is constrained to output a single valid codeword from the received word could not tolerate a greater fraction of errors. This resulted in a gap between the error-correction performance for stochastic noise models (proposed by Shannon) and the adversarial noise model (considered by Richard Hamming). Since the mid 90s, significant algorithmic progress by the coding theory community has bridged this gap. Much of this progress is based on a relaxed error-correction model called list decoding, wherein the decoder outputs a list of codewords for worst-case pathological error patterns where the actual transmitted codeword is included in the output list. In case of typical error patterns though, the decoder outputs a unique single codeword, given a received word, which is almost always the case (However, this is not known to be true for all codes). The improvement here is significant in that the error-correction performance doubles. This is because now the decoder is not confined by the half-the-minimum distance barrier. This model is very appealing because having a list of codewords is certainly better than just giving up. The notion of list-decoding has many interesting applications in complexity theory.

The Galápagos National Park Service systematically culls feral predators and competitors. Goat eradication on islands, including Pinta, was achieved by the technique of using "Judas goats" with radio location collars to find the herds. Marksmen then shot all the goats except the Judas, and then returned weeks later to find the "Judas" and shoot the herd to which it had relocated. Goats were removed from Pinta Island after a 30-year eradication campaign, the largest removal of an insular goat population using ground-based methods. Over 41,000 goats were removed during the initial hunting effort (1971–82). This process was repeated until only the "Judas" goat remained, which was then killed. Other measures have included dog eradication from San Cristóbal, and fencing off nests to protect them from feral pigs.

As with every computational practice, in affect detection by facial processing, some obstacles need to be surpassed, in order to fully unlock the hidden potential of the overall algorithm or method employed. In the early days of almost every kind of AI-based detection (speech recognition, face recognition, affect recognition), the accuracy of modeling and tracking has been an issue. As hardware evolves, as more data are collected and as new discoveries are made and new practices introduced, this lack of accuracy fades, leaving behind noise issues. However, methods for noise removal exist including neighborhood averaging, linear Gaussian smoothing, median filtering, or newer methods such as the Bacterial Foraging Optimization Algorithm.

Mercury-Redstone 3 finally lifted off at 9:34 am. ET, watched by an estimated 45 million television viewers in the United States. Shepard was subjected to a maximum acceleration of 6.3g just before the Redstone engine shut down, two minutes and 22 seconds after launch. "Freedom 7's" space-fixed velocity was , close to the planned value. Upon shutdown of the booster, the escape tower was jettisoned. Ten seconds later came capsule separation: the capsule detonated the explosive bolts on the Marman clamping ring that joined it to the booster and fired its posigrade rockets to gain distance. After capsule separation, the automated attitude control system (the Automatic Stabilization Control System, or ASCS) damped out any residual tumbling motions and then yawed "Freedom 7" around 180 degrees, so the retrorockets would face forward ready for firing.

The popular magazine "Oggi" simultaneously nicknamed the animal "Ciro", a typical Neapolitan boy's name, an idea by chief-editor Pino Aprile. In 1994 Leonardi published a larger article about the discovery. In 1995 Marco Signore of the University of Naples Federico II submitted a thesis containing a lengthy description of the fossil, in which he named it "Dromaeodaimon irene". Because the thesis was unpublished this remained an invalid "nomen ex dissertatione". Meanwhile, in Salerno, Sergio Rampinelli had begun a further preparation of the fossil, during three hundred hours of work removing the fake tail, replacing the vinyl glue with a modern resin preservative and finishing the uncovering of the bones. On this occasion it was discovered that large parts of the soft tissues had been preserved.

On ascent from a dive, inert gas comes out of solution in a process called "outgassing" or "offgassing". Under normal conditions, most offgassing occurs by gas exchange in the lungs. If inert gas comes out of solution too quickly to allow outgassing in the lungs then bubbles may form in the blood or within the solid tissues of the body. The formation of bubbles in the skin or joints results in milder symptoms, while large numbers of bubbles in the venous blood can cause lung damage. The most severe types of DCS interrupt — and ultimately damage — spinal cord function, leading to paralysis, sensory dysfunction, or death. In the presence of a right-to-left shunt of the heart, such as a patent foramen ovale, venous bubbles may enter the arterial system, resulting in an arterial gas embolism. A similar effect, known as ebullism, may occur during explosive decompression, when water vapour forms bubbles in body fluids due to a dramatic reduction in environmental pressure.

The carbon–iodine bond is a common functional group that forms part of core organic chemistry; formally, these compounds may be thought of as organic derivatives of the iodide anion. The simplest organoiodine compounds, alkyl iodides, may be synthesised by the reaction of alcohols with phosphorus triiodide; these may then be used in nucleophilic substitution reactions, or for preparing Grignard reagents. The C–I bond is the weakest of all the carbon–halogen bonds due to the minuscule difference in electronegativity between carbon (2.55) and iodine (2.66). As such, iodide is the best leaving group among the halogens, to such an extent that many organoiodine compounds turn yellow when stored over time due to decomposition into elemental iodine; as such, they are commonly used in organic synthesis, because of the easy formation and cleavage of the C–I bond. They are also significantly denser than the other organohalogen compounds thanks to the high atomic weight of iodine. A few organic oxidising agents like the iodanes contain iodine in a higher oxidation state than −1, such as 2-iodoxybenzoic acid, a common reagent for the oxidation of alcohols to aldehydes, and iodobenzene dichloride (PhICl), used for the selective chlorination of alkenes and alkynes. One of the more well-known uses of organoiodine compounds is the so-called iodoform test, where iodoform (CHI) is produced by the exhaustive iodination of a methyl ketone (or another compound capable of being oxidised to a methyl ketone), as follows:

While this mechanism in the roots responds to exudates and involves competition over resources like nitrogen and phosphorus, another mechanism has been recently proposed, which involves competition over light, in which kin recognition takes place in leaves. In their 2014 study, Crepy and Casal conducted multiple experiments on different accessions of "A. thaliana". These experiments showed that "Arabidopsis" accessions have distinct R:FR and blue light signatures, and that these signatures can be detected by photoreceptors, which allows the plant to recognize its neighbor as a relative or non-relative. Not much is known about the pathway that "Arabidopsis" uses to associate these light patterns with kin, however, researchers ascertained that photoreceptors phyB, cry 1, cry 2, phot1, and phot2 are involved in the process by performing a series of experiments with knock-out mutants. Researchers also concluded that the auxin-synthesis gene TAA1 is involved in the process, downstream of the photoreceptors, by performing a similar experiments using Sav3 knock-out mutants. This mechanism leads to altered leaf direction to prevent shading of related neighbors and to reduce competition for sunlight.

"Bayonetta 3", like its predecessors, is an action hack and slash game in which players control the eponymous protagonist Bayonetta as she combats various enemies using a combination of melee attacks and gunplay. Dodging enemy attacks at the last second triggers a state known as "Witch Time", during which time and enemies slow down, allowing Bayonetta to continually attack them without interruption, or traverse in real-time to solve environmental puzzles. Unique to this game are the "Demon Slave" and "Demon Masquerade" mechanics, the former of which differs from the preceding Climax Summon and Umbran Climax features in the first two titles, and instead allows players to take direct control of one of Bayonetta's Infernal Demons to perform various attacks and special abilities, some of which are advantageous to particular scenarios depending on the demon being controlled. The latter meanwhile, allows Bayonetta to directly fuse with a summoned Infernal Demon, granting her access to magic-based abilities, including new attack and traversal options. A new playable character, Viola, can only activate Witch Time through the use of a parry mechanic, and whose only Demon Slave Cheshire cannot be manually controlled. When Viola summons Cheshire, she switches from a sword-based fighting style to a fist-based fighting style.

AC traction still occasionally uses dual overhead wires instead of single-phase lines. The resulting three-phase current drives induction motors, which do not have sensitive commutators and permit easy realisation of a regenerative brake. Speed is controlled by changing the number of pole pairs in the stator circuit, with acceleration controlled by switching additional resistors in, or out, of the rotor circuit. The two-phase lines are heavy and complicated near switches, where the phases have to cross each other. The system was widely used in northern Italy until 1976 and is still in use on some Swiss rack railways. The simple feasibility of a fail-safe electric brake is an advantage of the system, while speed control and the two-phase lines are problematic.

Certain aspects of language and melody have been shown to be processed in near identical functional brain areas. Brown, Martinez and Parsons (2006) examined the neurological structural similarities between music and language. Utilizing positron emission tomography (PET), the findings showed that both linguistic and melodic phrases produced activation in almost identical functional brain areas. These areas included the primary motor cortex, supplementary motor area, Broca's area, anterior insula, primary and secondary auditory cortices, temporal pole, basal ganglia, ventral thalamus and posterior cerebellum. Differences were found in lateralization tendencies as language tasks favoured the left hemisphere, but the majority of activations were bilateral which produced significant overlap across modalities.

Bristow was thus assigned with the charge of constructing an approach channel from the deep sea to the inner harbour. This would help ships to enter the safer harbour rather than be exposed to the violent sea where they currently berthed while offloading cargo. The challenge Bristow faced in his task, was the obstruction caused due to a rock-like sand bar that guarded the entrance to the port. However, he was widely optimistic, and started off with a detailed study of the harbour and submitted a report to Lord Willingdon, the Governor of Madras. For the next twenty one years, he was involved with the construction of the port and succeeded in transforming Kochi into one of the safest harbours in the peninsula, where ships berthed alongside the newly reclaimed inner harbour equipped with a long array of steam cranes. The steamship "Padma", sailing from Bombay on 26 May 1928, was the first major ship to enter the newly constructed inner harbour of Kochi.

Schrödinger asked the question: "How does the living organism avoid decay?" The obvious answer is: "By eating, drinking, breathing and (in the case of plants) assimilating." While energy from nutrients is necessary to sustain an organism's order, Schrödinger also presciently postulated the existence of other molecules equally necessary for creating the order observed in living organisms: "An organism's astonishing gift of concentrating a stream of order on itself and thus escaping the decay into atomic chaos – of drinking orderliness from a suitable environment – seems to be connected with the presence of the aperiodic solids..." We now know that this "aperiodic" crystal is DNA, and that its irregular arrangement is a form of information. "The DNA in the cell nucleus contains the master copy of the software, in duplicate. This software seems to control by specifying an algorithm, or set of instructions, for creating and maintaining the entire organism containing the cell."

The term Energy Management System can also refer to a computer system which is designed specifically for the automated control and monitoring of those electromechanical facilities in a building which yield significant energy consumption such as heating, ventilation and lighting installations. The scope may span from a single building to a group of buildings such as university campuses, office buildings, retail stores networks or factories. Most of these energy management systems also provide facilities for the reading of electricity, gas and water meters. The data obtained from these can then be used to perform self-diagnostic and optimization routines on a frequent basis and to produce trend analysis and annual consumption forecasts.

Academic programs are spread across four distinct campuses in the Phoenix Metropolitan Area; unlike most multi-campus institutions, however, ASU describes itself as "one university in many places", inferring there is "not a system with separate campuses, and not one main campus with branch campuses." The university considers each campus "distinctive" and academically focused on certain aspects of the overall university mission. The Tempe campus is the university's research and graduate school center. Undergraduate studies on the Tempe campus are research-based programs that prepare students for graduate school, professional school, or employment. The Polytechnic campus is designed with an emphasis on professional and technological programs for direct workforce preparation. The Polytechnic campus is the site of many of the university's simulators and laboratories dedicated for project-based learning. The West campus is focused on interdisciplinary degrees and the liberal arts, while maintaining professional programs with a direct impact on the community and society. The Downtown Phoenix campus focuses on direct urban and public programs such as nursing, public policy, criminal justice, mass communication, and journalism. ASU recently relocated some nursing and health related programs to its new ASU-Mayo Medical School campus. Inter-campus shuttles and light rail allow students and faculty to easily travel between the campuses. In addition to the physical campuses, ASU's "virtual campus" at the university's SkySong Innovation Center, provides online and extended education.

In 2010, a pigment compound isolated and characterized from fruit bodies of "Mycena aurantiomarginata" was reported as new to science by Robert Jaeger and Peter Spiteller in the "Journal of Natural Products". The chemical, mycenaaurin A, is a polyene compound that consists of a tridecaketide (i.e., 13 adjacent methylene bridge and carbonyl functional groups with two amino acid moieties on either end of the molecule). The authors posit that the flanking amino acid groups are probably derived biosynthetically from "S"-Adenosyl methionine. The tridecaketide itself contains an alpha-pyrone, a conjugated hexaene, and a single alkenyl moiety. Jaeger and Spiteller suggest that mycenaaurin A might function as a defense compound, since it exhibits antibacterial activity against the Gram-positive bacterium "Bacillus pumilus". The chemical is only present in the fruit bodies, and not in the colorless mycelia. An earlier screening for antimicrobial activity in the fruit bodies revealed a weak ability to inhibit the growth of the fungi "Candida albicans" and "Aspergillus fumigatus".

While Hubble helped to refine estimates of the age of the universe, it also upended theories about its future. Astronomers from the High-z Supernova Search Team and the Supernova Cosmology Project used ground-based telescopes and HST to observe distant supernovae and uncovered evidence that, far from decelerating under the influence of gravity, the expansion of the universe is instead accelerating. Three members of these two groups have subsequently been awarded Nobel Prizes for their discovery. The cause of this acceleration remains poorly understood; the term used for the currently-unknown cause is dark energy, signifying that it is dark (unable to be directly seen and detected) to our current scientific instruments.

Detailed sample preparation depends on the type of material. Pure standards are most likely to be prepared by chemical synthesis and purification and characterized by determination of remaining impurities. This is often done by commercial producers. Natural matrix CRMs (often shortened to 'matrix CRMs') contain an analyte or analytes in a natural sample (for, example, lead in fish tissue). These are typically produced by homogenization of a naturally occurring material followed by measurement of each analyte. Due to the difficulty in production and value assignment, these are usually produced by national or transnational metrology institutes like NIST (USA), BAM (Germany), KRISS (Korea) and EC JRC ( European Commission Joint Research Centre).

The Cirrus SR (Single Reciprocating) Series aircraft (including the SRV, SR20, SR22 and SR22T) are produced with "Cirrus Perspective" by Garmin (and previously Avidyne Entegra) integrated digital flight displays and modern avionics as standard equipment, a first in the light general aviation (GA) manufacturing industry when the Entegra instrument panel became available on the series in 2003. The aircraft are all electric - no vacuum systems are used. Redundancy is provided by dual batteries and alternators. The series originally began as a four-seat aircraft, with a smaller fifth seat added in 2013. The SR22 is also available with TKS anti-icing equipment, which has enabled flight into known icing (FIKI) conditions since 2009. The SR aircraft series was the first of its kind to come equipped with flight envelope protection in the form of an electronic "level" button, as well as "airbag seatbelts", two airbags installed in the shoulder harnesses of both the pilot and co-pilots' seat belts.

Following the treatment of the acute disease, eradication treatment with co-trimoxazole is the drug of choice and should be used for 3 months (12 weeks) as all-cause mortality was lower in 12 weeks group when compared to those receiving treatment for 20 weeks. For those with neurological melioidosis and osteomyelitis, drugs should be given for more than 6 months. Co-amoxiclav and doxycycline are drugs of second choice. Co-trimoxazole should not be used in those with glucose-6-phosphate dehydrogenase deficiency as it can cause haemolytic anemia. However, in Thailand, usage of co-trimoxazole does not accompany G6PD screening. Other side effects such as rash, hyperkalemia, renal dysfunction, and gastrointestinal symptoms should prompt the reduction of co-trimoxazole doses. Chloramphenicol is no longer routinely recommended for this purpose. Co-amoxiclav is an alternative for patients unable to take co-trimoxazole and doxycycline (e.g. pregnant women and children under the age of 12), but is not as effective and has a higher relapse rate. Single-agent treatment with fluoroquinolone (e.g., ciprofloxacin) or doxycycline for the oral eradication phase is ineffective.

The reactive enodiolate species is also sensitive to oxygen (O), which results in the dual carboxylase / oxygenase activity of RuBisCO. This reaction is considered wasteful as it produces products (3-phosphoglycerate and 2-phosphoglycolate) that must be catabolized through photorespiration. This process requires energy and is a missed-opportunity for CO fixation, which results in the net loss of carbon fixation efficiency for the organism. The dual carboxylase / oxygenase activity of RuBisCO is exacerbated by the fact that O and CO are small, relatively indistinguishable molecules that can bind only weakly, if at all, in Michaelis-Menten complexes. There are four forms of RuBisCO (Form I, II, III, and IV), with Form I being the most abundantly used form. Form I is used extensively by higher plants, eukaryotic algae, cyanobacteria, and Pseudomonadota (formerly proteobacteria). Form II is also used but much less widespread, and can be found in some species of Pseudomonadota and in dinoflagellates. RuBisCOs from different photosynthetic organisms display varying abilities to distinguish between CO and O. This property can be quantified and is termed "specificity" (S). A higher value of S means that a RuBisCO's carboxylase activity is greater than its oxygenase activity.

In 1951 (Vol. 1) and 1953 (Vol. 2), Whittaker published an extended and revised edition of his book in two volumes. The first volume is a revision of the original 1910 book while the second volume, published two years later, contains an extension of the history into the twentieth century, covering the years 1900 through 1926. The books are considered authoritative texts on the developments of classical electromagnetism and continue to be cited by widely adopted textbooks on the subject. A third volume, covering the years 1925 to 1950, was promised in the second edition but was never published, as Whittaker died in 1956. The two volumes provide an account of the historical development of the fundamental theories of physics and they are said to "contain the distilled essence of their author's reading and study over a period of more than half a century."

During their media release in April 2018, Dr. Mahdi Zeraati and colleagues mentioned that these complexes are constantly forming and dissociating due to their constantly changing temperatures, which could play a role in its function in regulation of gene expression and cell reproduction. Although the exact function of these structures is unknown, the transient nature of these molecules gives insight regarding the biological function of these molecules. Found primarily in the G1 phase of the cell cycle and in promoter regions, i-motif complexes could potentially affect which gene sequences are read and could play a role in determining which genes are switched on or off. Other experimentation is in progress to determine the role of i-motif DNA in nanotechnology using i-motifs as biosensors and nanomachines, and it has even been seen to play a role in the advancement of cancer therapy.

If particle collisions produce mini black holes then energetic collisions such as the ones produced in the Large Hadron Collider (LHC) could trigger such a vacuum decay event, a scenario which has attracted the attention of the news media. It is likely to be unrealistic, because if such mini black holes can be created in collisions, they would also be created in the much more energetic collisions of cosmic radiation particles with planetary surfaces or during the early life of the universe as tentative primordial black holes. Hut and Rees note that, because cosmic ray collisions have been observed at much higher energies than those produced in terrestrial particle accelerators, these experiments should not, at least for the foreseeable future, pose a threat to our current vacuum. Particle accelerators have reached energies of only approximately eight tera electron volts (8×10 eV). Cosmic ray collisions have been observed at and beyond energies of 5×10 eV, six million times more powerful – the so-called Greisen–Zatsepin–Kuzmin limit – and cosmic rays in vicinity of origin may be more powerful yet. John Leslie has argued that if present trends continue, particle accelerators will exceed the energy given off in naturally occurring cosmic ray collisions by the year 2150. Fears of this kind were raised by critics of both the Relativistic Heavy Ion Collider and the Large Hadron Collider at the time of their respective proposal, and determined to be unfounded by scientific inquiry.

Very early in his career he employed several traditional drawing and wash techniques to render illustrations. Dissatisfied with traditional techniques he explored other means of rendering that would allow him to realistically render the brilliant highlights and fine fibers of living tissue. In 1894 after arriving in Baltimore and after some experimentation he began using the dust of Wolff carbon pencils applied to Ross .00 stipple board. Ross board was similar to coquille board and was coated with chalk, that was textured with fine bumps or stipples that helped hold the dust on the surface and aided reproduction for printing. The chalk coating allowed for multiple scratches to create highlights and rework of the dust. Brödel preferred sable brushes for applying dust. To smudge and erase the applied dust he used a variety of customized tools. He modified sable brushes to shorten the bristles to increase their stiffness. He carved rubber erasers, bits of cork and chamois, then secured them in brass charcoal holders for use on drawings. For scratching he modified an engraving tool. Holding this tool at various angles allowed him to vary the width of a scratch. Later illustrators have used scalpels and knives for scratching.

The 2006 observation of a pair of colliding galaxy clusters known as the "Bullet Cluster", poses a significant challenge for all theories proposing a modified gravity solution to the missing mass problem, including MOND. Astronomers measured the distribution of stellar and gas mass in the clusters using visible and X-ray light, respectively, and in addition mapped the inferred dark matter density using gravitational lensing. In MOND, one would expect the "missing mass" to be centred on regions of visible mass which experience accelerations lower than a (assuming the external field effect is negligible). In ΛCDM, on the other hand, one would expect the dark matter to be significantly offset from the visible mass because the halos of the two colliding clusters would pass through each other (assuming, as is conventional, that dark matter is collisionless), whilst the cluster gas would interact and end up at the centre. An offset is clearly seen in the observations. It has been suggested, however, that MOND-based models may be able to generate such an offset in strongly non-spherically symmetric systems, such as the Bullet Cluster.

Off-the-shelf building materials (e.g., plywood, strand board) normally come in rectangular shapes, therefore some material may have to be scrapped after cutting rectangles down to triangles, increasing the cost of construction. Fire escapes are problematic; codes require them for larger structures, and they are expensive. Windows conforming to code can cost anywhere from five to fifteen times as much as windows in conventional houses. Professional electrical wiring costs more because of increased labor time. Even owner-wired situations are costly, because more of certain materials are required for dome construction. Expansion and partitioning is also difficult. Kahn notes that domes are difficult if not impossible to build with natural materials, generally requiring plastics, etc., which are polluting and deteriorate in sunlight.

The power loss can be minimized by increasing the reflectivity of the mirrors to as close to 1 as possible and by eliminating other, spurious, sources of power loss, for example the inaccuracy of mirror curvature. Any interfaces or apertures that would decrease the quality factor of the ring are avoided. The whole ring is filled with a HeNe mixture of suitable partial pressures (up to a few hundred Pascal), to achieve lasing and good suppression of multiple pairs of modes. (Typically, the HeNe lasing gas at 633 nm is used; attempts for an argon ring laser failed.) Further, the lasing is excited with radio frequency to easily adjust the amplitude to just below the appearance of the second pair of modes. The Rayleigh scattering of the HeNe gas is, at this time, negligible.

Hellins was born in Bow, Devon, the son of William Brock Hellins, a prison chaplain, and his wife, Elizabeth. He attended the University of Oxford as a bible scholar at All Souls College (B.A. 1851, then routinely upgraded to M.A.), becoming an ordained Church of England deacon (1852) and priest (1854); he was a Second Master at Exeter Grammar School, before becoming (Anglican) Chaplain to the Devon County Prison in Exeter in 1859, replacing his recently deceased father in the post. He married Eleanor Gard in 1857; they had two daughters and a son. His dedication, particularly to the rehabilitation of discharged prisoners, was well recognised. After around twelve years his health declined, including a near loss of his sight, and in 1879 the Church allowed him to retire (with one good eye) to a sinecure as a "clergyman without care of souls" with lodgings in the precinct of Exeter Cathedral, where his wife ran a day school, assisted by their two daughters and quite possibly by him. He died in Exeter.

As early as 1957, it was recognized that an increasing trend in the number of tropical cyclones each season in the Atlantic Basin was at least partially tied to increasing observations and better records. By analyzing the density of ship tracks over time, it has been estimated that between 1900 and 1966, an average of two storms per year are missing from HURDAT. This is mainly due to a lack of satellite imagery and lack of reconnaissance aircraft prior to 1943. An additional storm per year is likely missing prior to the advent of new technologies. These technologies include satellite-derived Quikscat winds, satellite-derived temperature profile information, and Robert Hart's cyclone phase space diagrams, which have led to a recent increase in tropical cyclone detection. Quikscat was launched in 1999, and has been credited with allowing Chantal to be named during the 2007 Atlantic hurricane season. The last two help determine whether or not a low pressure area is an extratropical cyclone, subtropical cyclone, or tropical cyclone.

Solar radiation is absorbed by the Earth's land surface, oceans – which cover about 71% of the globe – and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anticyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis, green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived.

To connect the telegraph to anywhere outside Britain, submarine telegraph cables were needed. The lack of a good insulator held back their development. Rubber was tried but degraded in salt water. The solution came with gutta-percha, a natural latex from trees of the genus "Palaquium" in the Far East. It sets harder than rubber when exposed to air, but when soaked in hot water it becomes plastic and mouldable. On cooling it rehardens. William Montgomerie, the head of the medical department in Singapore, brought the material to the attention of the Royal Society in 1843 when he sent samples of Gutta-percha to them. Montgomerie thought of using the material, in place of rubber which deteriorated rapidly in damp tropical conditions, to make medical equipment. After testing some samples, Michael Faraday recognised its potential for underwater cables.

The phrase "drug design" is to some extent a misnomer. A more accurate term is ligand design (i.e., design of a molecule that will bind tightly to its target). Although design techniques for prediction of binding affinity are reasonably successful, there are many other properties, such as bioavailability, metabolic half-life, side effects, etc., that first must be optimized before a ligand can become a safe and efficacious drug. These other characteristics are often difficult to predict with rational design techniques. Nevertheless, due to high attrition rates, especially during clinical phases of drug development, more attention is being focused early in the drug design process on selecting candidate drugs whose physicochemical properties are predicted to result in fewer complications during development and hence more likely to lead to an approved, marketed drug. Furthermore, in vitro experiments complemented with computation methods are increasingly used in early drug discovery to select compounds with more favorable ADME (absorption, distribution, metabolism, and excretion) and toxicological profiles.

The Imperium of Man is a human empire that comprises approximately 1 million worlds and has existed for over 10,000 years. Its government takes influences from a mixture of fascism, theocracy, and feudalism, as well as xenophobia. The state religion of the Imperium is centered around its founder, the Emperor of Mankind, an extremely powerful being worshipped as a god. Although the Emperor is its nominal ruler, he was mortally wounded in battle and is unable to rule directly. Despite his condition, his mind still generates a psychic beacon by which starships navigate through space, making him the linchpin of the Imperium's infrastructure. Although the Imperium has highly advanced technology, it has only recently continued the practice of science and many of its technologies have not improved for thousands of years. Most "Warhammer 40,000" fiction is written from the perspective of the Imperium, often with humans as protagonists.

From the Research and Development field comes the desire for more resolved, faster separations from smaller sample quantities. The only phase of drug development under direct control of a pharmaceutical company is the R&D stage. The goal of analytical work is to obtain as much information as possible from the sample. At this stage, high-throughput and analysis of tiny sample quantities are critical. Pharmaceutical companies are looking for tools that will better enable them to measure and predict the efficacy of candidate drugs in shorter times and with less expensive clinical trials. To this end, nano-scale separations, highly automated HPLC equipment, and multi-dimensional chromatography have become influential.

The geology of Morocco formed beginning up to two billion years ago, in the Paleoproterozoic and potentially even earlier. It was affected by the Pan-African orogeny, although the later Hercynian orogeny produced fewer changes and left the Maseta Domain, a large area of remnant Paleozoic massifs. During the Paleozoic, extensive sedimentary deposits preserved marine fossils. Throughout the Mesozoic, the rifting apart of Pangaea to form the Atlantic Ocean created basins and fault blocks, which were blanketed in terrestrial and marine sediments—particularly as a major marine transgression flooded much of the region. In the Cenozoic, a microcontinent covered in sedimentary rocks from the Triassic and Cretaceous collided with northern Morocco, forming the Rif region. Morocco has extensive phosphate and salt reserves, as well as resources such as lead, zinc, copper and silver.

Functional neuroimaging studies usually involve multiple participants, each of whom have differently shaped brains. All are likely to have the same gross anatomy, saving minor differences in overall brain size, individual variation in topography of the gyri and sulci of the cerebral cortex, and morphological differences in deep structures such as the corpus callosum. To aid comparisons, the 3D image of each brain is transformed so that superficial structures line up, via "spatial normalization". Such normalization typically involves translation, rotation and scaling and nonlinear warping of the brain surface to match a standard template. Standard brain maps such as the Talairach-Tournoux or templates from the Montréal Neurological Institute (MNI) allow researchers from across the world to compare their results.

The current impediment to large-scale IGZO manufacturing is the synthesis method. The most widely used technique for Transparent Conducting Oxide (TCO) synthesis is Pulsed Laser Deposition(PLD). In PLD, a laser is used to focus on nano-sized spots on solid elemental targets. Laser pulse frequencies are varied between the targets in ratios to control the composition of the film. IGZO can be deposited onto substrates such as quartz, single-crystal silicon, or even plastic due to its ability for low-temperature deposition. The substrates are placed in a PLD vacuum chamber, which controls oxygen pressure in order to ensure favorable electrical properties. After synthesis, the film is annealed, or gradually exposed to air to adjust to the atmosphere.

The pad abort test was conducted successfully on 6 May 2015 at SpaceX's leased SLC-40. Dragon landed safely in the ocean to the east of the launchpad 99 seconds after ignition of the SuperDraco engines. While a flight-like Dragon 2 and trunk were used for the pad abort test, they rested atop a truss structure for the test rather than a full Falcon 9 rocket. A crash test dummy embedded with a suite of sensors was placed inside the test vehicle to record acceleration loads and forces at the crew seat, while the remaining six seats were loaded with weights to simulate full-passenger-load weight. The test objective was to demonstrate sufficient total impulse, thrust and controllability to conduct a safe pad abort. A fuel mixture ratio issue was detected after the flight in one of the eight SuperDraco engines causing it to under perform, but did not materially affect the flight.

Goddard's father further encouraged Robert's scientific interest by providing him with a telescope, a microscope, and a subscription to "Scientific American". Robert developed a fascination with flight, first with kites and then with balloons. He became a thorough diarist and documenter of his work—a skill that would greatly benefit his later career. These interests merged at age 16, when Goddard attempted to construct a balloon out of aluminum, shaping the raw metal in his home workshop, and filling it with hydrogen. After nearly five weeks of methodical, documented efforts, he finally abandoned the project, remarking, "... balloon will not go up. ... Aluminum is too heavy. Failior crowns enterprise." However, the lesson of this failure did not restrain Goddard's growing determination and confidence in his work. He wrote in 1927, "I imagine an innate interest in mechanical things was inherited from a number of ancestors who were machinists."

S100A4 is highly associated with components of the cytoskeleton and when this gene is upregulated, it changes the cell’s morphology, making it more susceptible to invasion from proteins, such as cathepsin B and cyclin B1, that contribute to metastasis. Together, these factors form polyploid giant cancer cells (PGCCs), which are highly proliferative and invasive. Experimental knockout therapy data have suggested that S100A4 exhibits a form of control over cathepsin B and cyclin B1, and that suppressing it can reduce the invasive capabilities of PGCCs and their daughter cells. Studies on invasive breast cancer have found that S100A4 plays a major role in high-density collagen deposition, which is one of the clinical symptoms of tumor metastasis. Significantly higher levels of S100A4 were found in samples that exhibited lymph node metastasis than in those that didn’t, indicating that abnormal collagen deposition could be contributed to by S100A4. Not only does overexpression of S100A4 contribute to the formation of various cancers, but it also contributes to pathological factors associated with cancer and its progression.

Melanins are produced in organelles called melanosomes. The production of melanins is called melanogenesis. Melanosomes are found in specialized pigment cells called melanocytes, but may also be engulfed by other cells, which are then called melanophages. Hair acquires pigment from melanocytes in the root bulb, which deposit melanosomes into the growing hair structure. A critical step in the production of melanins is the catalysis of tyrosine by an enzyme called tyrosinase, producing dopaquinone. Dopaquinone may become eumelanin, or phaeomelanin. Eumelanin, meaning "true black", is a dense compound that absorbs most wavelengths of light, and appears black or brown as a result. Phaeomelanin, meaning "rufous-black", is characterized by the presence of sulfur-containing cysteine, and it appears reddish to yellowish as a result. Melanosomes containing eumelanin are eumelanosomes, while those containing phaeomelanin are phaeomelanosomes. Melanocyte-stimulating hormone (MSH) binds to the Melanocortin 1 receptor (MC1R) and commits melanocytes to the production of eumelanin. In the absence of this signal, melanocytes produce phaeomelanin. Another chemical, Agouti signalling peptide (ASP), can attach itself to MC1R and interfere with MSH/MC1R signalling. In many mammals, variation in the level of ASP switches melanocytes between eumelanin and phaeomelanin production, resulting in coloured patterns.

Almost all "free" hadrons and antihadrons (meaning, in isolation and not bound within an atomic nucleus) are believed to be unstable and eventually decay into other particles. The only known possible exception is free protons, which appear to be stable, or at least, take immense amounts of time to decay (order of 10 years). By way of comparison, free neutrons are the longest-lived unstable particle, and decay with a half-life of about 879 seconds. Experimentally, hadron physics is studied by colliding hadrons, e.g. protons, with each other or the nuclei of dense, heavy elements, such as lead or gold, and detecting the debris in the produced particle showers. A similar process occurs in the natural environment, in the extreme upper-atmosphere, where muons and mesons such as pions are produced by the collisions of cosmic rays with rarefied gas particles in the outer atmosphere.

RHBV is propagative, meaning it infects both host plants and its insect vector. "Tagosodes orizicolus" (changed from "Sogatodes orizycola" in 1993)"," is a species of planthopper, and the known common vector of RHBV. It belongs to the family "Delphacidae," as do the planthopper vectors of other "Tenuiviruses". "T. orizicolus" feed in the phloem of target plants, giving them the unique ability to infect plants without outright destroying plant tissue, which in turn promotes successful infection by RHBV. However, plants can be susceptible to "hopper burn", where excessive feeding cause an affected plant to dry up. Infection in "T. orizicolus" begins when a planthopper feeds on an infected plant. After the virus is acquired by the host, it will incubate for a period ranging for 4–31 days. The infected planthopper can then transmit the virus to new plants it feeds on. Vertical transmission is possible transovarially from infected females to their offspring and from males to their progeny, although RHBV is the only "Tenuivirus" known to be paternally transmitted. Transmission efficiency is variable between different populations of "T. orizicolus", and can be selectively bred to 100% efficiency over controlled generations.

Built in 1916, the original physical education building housed faculty and staff offices, gymnasiums, a track, multipurpose and meeting rooms, a strength training center, a therapeutic/rehabilitation swimming pool, the Musculoskeletal Research Center, and the Special Populations Exercise Program. The building has been renovated for use in the preparation of special/adapted physical education teachers and therapeutic recreation specialists. Administrative, faculty, staff, and graduate assistant offices for the Department of Recreation Management and Therapeutic Recreation are located in Wittich Hall. The building is also the primary practice site for the Women's Intercollegiate Athletics Gymnastics team. Wittich Hall, the Physical Education Building of the La Crosse State Normal School, was listed in the National Register of Historic Places in 1985 as the Physical Education Building/La Crosse State Normal School. In Fall 2020, Wittich Hall was re-opened as the home of the College of Business Administration.

Over the years newer and tougher composites have been developed, giving about five times the protection value of the original pure ceramics, the best of which were again about five times as effective as a steel plate of equal weight. These are often a mixture of several ceramic materials, or metal matrix composites which combine ceramic compounds within a metal matrix. The latest developments involve the use of carbon nanotubes to improve toughness even further. Commercially produced or researched ceramics for such type of armour include boron carbide, silicon carbide, aluminium oxide (sapphire or "alumina"), aluminium nitride, titanium boride and Syndite, a synthetic diamond composite. Of these boron carbide is the hardest and lightest, but also the most costly and brittle. Boron carbide composites are today favoured for ceramic plates protecting against smaller projectiles, such as used in body armour and armoured helicopters; this was, in the early sixties, the first general application of ceramic armour. Silicon carbide is better suited to protect against larger projectiles than boron carbide as the latter material suffers a phase collapse when impacted by a projectile travelling at a speed over 850 m/s. Silicon carbide was at that time only used in some prototype land vehicles, such as the MBT-70. The ceramics can be created by pressureless sintering or hot pressing. A high density is required, so residual porosity must be minimised in the final part.
