The Oxford University Polo Club was founded in 1874 by Walter Hume Long (1854–1929), later Viscount Long of Wraxall and First Lord of the Admiralty. Together with his group of friends going up from Wiltshire to Oxford, he founded this new club with matches on a cut hay-field in Port Meadow near Wolvercote (Oxford). This field, which was 280 yards long by 170 yards wide was to become the foundation for the club's own pologrounds for decades to come. Later, the ground was prepared with old turf and could be played in all weather conditions as it hardly ever cut up (from 1930 it was also boarded). During the winter months, matches took place on the Bullingdon Club cricket ground, Cowley, as the summer pitch in Port Meadow was subject to flooding from the River Isis. The club played all year round, mostly on hirelings; playing days were Mondays, Wednesdays and Fridays and the number of playing members seems to have averaged about a dozen. First records show that the club was playing in Hurlingham in 1876 as well as organising an exhibition match between Christ Church and Brasenose College at Christ Church Meadow on 1 July 1877. During the first decade, teams consisted of five members until the set up was replaced in 1883 by the modern game of polo.

Demonstration of the T-18 took place in mid-May 1927, but in combat tests its ability to move over rough terrain and fight effectively were not immediately apparent. A special commission comprising representatives of the Supreme Economic Council Mobupravleniya, OAT factory "Bolshevik", Artupravleniya, and the headquarters of the Red Army were on hand for the tests. During trials to overcome obstacles the T-18 behaved no better than the FT, with its biggest problem being trenches or ditches wider than 2 m and deeper than approximately 1.2 m. The machines often became stuck trying to cross these obstacles and needed to be pulled out by a tractor or another tank. However, the T-18 proved to be more "nimble" than the FT or T-16 and had a maximum road speed of 18 km/h. In addition, in comparison with foreign analogues, the T-18 had better armour and a little more room for ammunition reserves.

In 1977 the wing span stretch of the TC model was applied to the base 112 to produce the 112B. This allowed the 112B's maximum takeoff weight to rise to , giving it a respectable useful load of . Production of the 112B ended in 1979, while the 112TC was further upgraded with a maximum weight increase and minor detail changes. The major change was a complete makeover of the avionics suite with a three-axis autopilot, producing the 112TCA "Alpine". This offered little more performance than the original 112TC, and was more expensive than similar offerings from other companies. A smaller set of upgrades, notably a three-bladed propeller and a slightly raised maximum takeoff weight of , produced the 114A "Gran Turismo". The 112TCA and 114A remained in production until 1980, when Rockwell shut down the production line with about 1,000 examples of the different models being delivered.

In some cases the symbiosis between fungus and plant reaches a point of inseparability; fungal material is transmitted vertically from the maternal parent plant to seeds, forming a near-obligate mutualism. Having a mutualistic relationship with endophytic fungi can promote seed production and seed germination rates in some plant species, such as perennial ryegrass ("Lolium perenne") and tall fescue ("Festuca arundinacea"). The fungi can also benefit the growth of the seedlings as it can enhance seedling growth rate, tiller number and height, and overall biomass. Because seeds are an important aspect of both fecundity and competitive ability for plants, high germination rates and seedling survival increase lifetime fitness. When fitness of plant and fungus become tightly intertwined, it is in the best interest of the endophyte to act in a manner beneficial to the plant, pushing it further toward the mutualism end of the continuum. Such effects of seed defense can also occur in dense stands of conspecifics through horizontal transmission of beneficial fungi. Mechanisms of microbial association defense, protecting the seeds rather than the already established plants, can have such drastic impacts on seed survival that they have been recognized to be an important aspect of the larger ‘seed defence theory’.

In addition, there is no consensus on what sort of value to give the rest of the corn (such as the stalk), commonly known as the 'coproduct.' Some studies leave it on the field to protect the soil from erosion and to add organic matter, while others take and burn the coproduct to power the ethanol plant, but do not address the resulting soil erosion (which would require energy in the form of fertilizer to replace). Depending on the ethanol study you read, net energy returns vary from .7-1.5 units of ethanol per unit of fossil fuel energy consumed. For comparison, that same one unit of fossil fuel invested in oil and gas extraction (in the lower 48 States) will yield 15 units of gasoline, a yield an order of magnitude better than current ethanol production technologies, ignoring the energy quality arguments above and the fact that the gain (14 units) is both declining and not carbon neutral.

The genus "Ptilotus", compromising around 100 species is almost completely confined to Australia, with a one species extending to Timor and certain surrounding islands. "Ptilotus exaltatus" itself is endemic to much of mainland Australia and grows abundantly throughout the entirety of the country, favouring arid and semi-arid climates for ideal growth. Large parts of Australia in which the plant grows experience frosts during winter months, which Ptilotus can withstand by going dormant for short periods of time. Conversely, they are extremely heat and drought tolerant although their lifespan is relatively short – they exist healthily for only a few years. Given the nature of weather patterns in arid Australia – often involving long dry patches followed by brief downpours of rain, "Ptilotus exaltatus" most often grows immediately after precipitation. Large numbers of the species have been observed to sprout after rainfall in desert areas, and the species is adept at surviving with lower water requirements after initial sprouting.

Once medically stable, people may be transferred to a subacute rehabilitation unit of the medical center or to an independent rehabilitation hospital. Rehabilitation aims to improve independent functioning at home and in society, and to help adapt to disabilities. Rehabilitation has demonstrated its general effectiveness when conducted by a team of health professionals who specialize in head trauma. As for any person with neurologic deficits, a multidisciplinary approach is key to optimizing outcome. Physiatrists or neurologists are likely to be the key medical staff involved, but depending on the person, doctors of other medical specialties may also be helpful. Allied health professions such as physiotherapy, speech and language therapy, cognitive rehabilitation therapy, and occupational therapy will be essential to assess function and design the rehabilitation activities for each person. Treatment of neuropsychiatric symptoms such as emotional distress and clinical depression may involve mental health professionals such as therapists, psychologists, and psychiatrists, while neuropsychologists can help to evaluate and manage cognitive deficits. Social workers, rehabilitation support personnel, nutritionists, therapeutic recreationists, and pharmacists are also important members of the TBI rehabilitation team. After discharge from the inpatient rehabilitation treatment unit, care may be given on an outpatient basis. Community-based rehabilitation will be required for a high proportion of people, including vocational rehabilitation; this supportive employment matches job demands to the worker's abilities. People with TBI who cannot live independently or with family may require care in supported living facilities such as group homes. Respite care, including day centers and leisure facilities for disabled people, offers time off for caregivers, and activities for people with TBI.

The Company inherited a revenue collection system from the Mughals in which the heaviest proportion of the tax burden fell on the cultivators, with one-third of the production reserved for imperial entitlement; this pre-colonial system became the Company revenue policy's baseline. There was vast variation across India in the methods by which the revenues were collected; with this complication in mind, a Committee of Circuit toured the districts of expanded Bengal presidency in order to make a five-year settlement, consisting of five-yearly inspections and temporary tax farming. In their overall approach to revenue policy, Company officials were guided by two goals: preserving as much as possible the balance of rights and obligations that were traditionally claimed by the farmers who cultivated the land and the various intermediaries who collected tax on the state's behalf and who reserved a cut for themselves and identifying those sectors of the rural economy that would maximize both revenue and security. Although their first revenue settlement turned out to be essentially the same as the more informal previous Mughal one, the Company had created a foundation for the growth of both information and bureaucracy.

In 1758, Benjamin Franklin and John Hadley, professor of chemistry, collaborated on a project investigating the principle of evaporation as a means to rapidly cool an object at Cambridge University, England. They confirmed that the evaporation of highly volatile liquids, such as alcohol and ether, could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to quicken the evaporation; they lowered the temperature of the thermometer bulb down to , while the ambient temperature was . They noted that soon after they passed the freezing point of water , a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about a thick when they stopped the experiment upon reaching . Franklin wrote, "From this experiment, one may see the possibility of freezing a man to death on a warm summer's day". In 1805, American inventor Oliver Evans described a closed vapor-compression refrigeration cycle for the production of ice by ether under vacuum.

Rehabilitation psychology is a specialty area of psychology aimed at maximizing the independence, functional status, health, and social participation of individuals with disabilities and chronic health conditions. Assessment and treatment may include the following areas: psychosocial, cognitive, behavioral, and functional status, self-esteem, coping skills, and quality of life. As the conditions experienced by patients vary widely, rehabilitation psychologists offer individualized treatment approaches. The discipline takes a holistic approach, considering individuals within their broader social context and assessing environmental and demographic factors that may facilitate or impede functioning. This approach, integrating both personal (e.g., deficits, impairments, strengths, assets) and environmental factors, is consistent with the World Health Organization's (WHO) International Classification of Functioning, Disability and Health (ICF).

Regeneration research using Planarians began in the late 1800s and was popularized by T.H. Morgan at the beginning of the 20th century. Alejandro Sanchez-Alvarado and Philip Newmark transformed planarians into a model genetic organism in the beginning of the 20th century to study the molecular mechanisms underlying regeneration in these animals. Planarians exhibit an extraordinary ability to regenerate lost body parts. For example, a planarian split lengthwise or crosswise will regenerate into two separate individuals. In one experiment, T.H. Morgan found that a piece corresponding to 1/279th of a planarian or a fragment with as few as 10,000 cells can successfully regenerate into a new worm within one to two weeks. After amputation, stump cells form a blastema formed from neoblasts, pluripotent cells found throughout the planarian body. New tissue grows from neoblasts with neoblasts comprising between 20 and 30% of all planarian cells. Recent work has confirmed that neoblasts are totipotent since one single neoblast can regenerate an entire irradiated animal that has been rendered incapable of regeneration. In order to prevent starvation a planarian will use their own cells for energy, this phenomenon is known as de-growth.

Blattabacterium lives inside the fat cells of the fat bodies (tissues in the abdominal cavity that store fat) of its insect hosts. It serves a vital role in nitrogen recycling, which is important in insects that mainly live on plant material such as wood, which are poor in nitrogen. In insects, uric acid is a waste product of protein metabolism. After breakdown of uric acid by the host (and its other microbial flora, such as gut bacteria and fungi) into urea and/or ammonia, blattabacterium recycles nitrogen by converting these products into glutamate, and using other raw materials from the host, is able to synthesize all of the essential amino acids and several vitamins. It appears to be transmitted to succeeding generations of the host by infection of the mother's eggs prior to their fertilization.

Dinosaur faunas of the Judithian age may represent the peak of dinosaur evolution in North America. Hadrosaurs were universally the dominant herbivore of the period and comprised more than half of "a typical assemblage." This was also the period of greatest generic diversity among large herbivorous dinosaurs. Just in Montana and Southern Alberta were ten genera of ceratopsians and ten genera of hadrosaurs. An association between "Centrosaurus" and "Corythosaurus" is characteristic of southern Alberta. Earlier research had found that lambeosaurines are less common in contemporary Montanan strata and with different centrosaurs as "Monoclonius" taking the place of "Centrosaurus". Inland environments also differed, with the contemporary Two Medicine Formation preserving an inland fauna characterized by "Maiasaura" and the early pachyrhinosaur "Einiosaurus". Farther south was characterized by lower taxonomic diversity in communities where lambeosaurines were less common and centrosaurs were completely lacking. There "Kritosaurus", "Parasaurolophus" and "Pentaceratops" are the dominant fauna. The giant eusuchian "Deinosuchus" is also "conspicuous" in the southern biome. Farther south, in Texas, "Kritosaurus" predominates. The biomes of the Eastern US may have resembled those of Texas except completely lacking in ceratopsians. "Parasaurolophus" and "Kritosaurus" are also present in northern latitudes, so evidently exchange between them occurred, but both are uncommon outside of the southern biome.

Semple's early education was guided by her mother, Emerine Semple, as well as private tutors. Semple followed her sister, Patty Semple, to Vassar where she graduated as valedictorian and was the youngest member of her graduating class. Semple graduated in 1882 with a BA in History from Vassar College at the age of 19, and continued on at Vassar to earn an MA in History in (1891). She became interested in geography while visiting London, where she encountered the works of Friedrich Ratzel. She went to Germany to seek out Ratzel and study with him at the University of Leipzig. As a woman, she was prohibited from matriculating, but she was able to gain permission to attend Ratzel's lectures, the only woman in a class of five hundred male students. She continued to work with Ratzel and produced several academic papers in American and European journals, but was never conferred a degree.

Cheyne had a deep aversion against pain. He concluded "The English Malady" (1733) by stating that he was one of those "mean-spirited Wretches" who was content to live as long as nature designed him to last and that he would submit with the utmost peace and resignation he could arrive at when his life had to end. But pain, sickness, and especially oppression, anxiety and lowness were his "mortal Aversion" and he added that he would refuse no means to avoid them, except those that would bring him even greater suffering. For he knew there were as many and different degrees of sensibility or of feeling as there were degrees of intelligence and perception in human beings. One perhaps suffered more from the "Prick of a Pin" than others from being "run through their Body", and the first sort seemed to be of the class of the "Quick-Thinkers". None could, however, choose for themselves their own particular frame of mind, nor constitution of body, just as they could not choose their own degree of sensibility, for that was given by the "Author of his Nature", and was already determined. Both were as various as the faces and forms of mankind.

When the U.S. Air Force became a separate service in 1947, Air Force pathfinders were assigned to a provisional "Pathfinder Squadron". The Air Force looked for ways to get rid of pathfinders, believing that electronic navigation aids could replace them and the pathfinders role became increasingly neglected by the Air Force. During the Korean War pathfinders were only used in the three main airdrops early in the war. Meanwhile, in Washington D.C. the Air Force and Army leadership were at odds about which service would have ownership of the pathfinder mission. The Department of Defense eventually sided with the Air Force having full control of all air traffic control duties. Despite the resolution the Army never inactivated their pathfinder units which has subsequently become more specialized towards helicopters. After the DOD sided with the Air Force being chosen for the pathfinder mission they expected six teams of pathfinders to be formed from Army-to-Air Force transfers but only got eleven men, enough to form one team. In 1953 the Pathfinder Squadron was discontinued and the pathfinder team was assigned to the 1st Aerial Port Squadron and officially designated a Combat Control Team. The Senior non-commissioned officer of this founding cadre was MSgt "Bull" Benini, he took the lead in establishing the team's new tactics, procedures, organization, and logistics requirements.

An examination of the calibration curve, which has a time resolution of five years, showed three intervals in the last 3,000 years in which C increased significantly. On the basis of this two Japanese cedar trees were examined with a resolution of a single year, and showed an increase of 1.2% in AD 774, some twenty times larger than anything expected from the normal solar variation. This peak steadily diminished over the next few years. The result was confirmed by studies of German oak, bristlecone pine from California, Siberian larch, and Kauri wood from New Zealand. All determinations agreed on both the time and amplitude of the effect. In addition, measurements of coral skeletons from the South China Sea showed substantial variations in C over a few months around the same time; however, the date could only be established to within a period of ±14 years around 783 AD.

Not all patients are candidates for VATS lobectomy. The classic indication for a VATS approach to lobectomy is early stage lung cancer in which the primary tumor is 3 cm or less in diameter and located toward the periphery of the lung parenchyma. Tumors that are located close to the major blood vessels or airway where these enter the lung or larger tumors associated with tumor spread to lymph nodes in the central regions of the lung may require the enhanced tactile input afforded by thoracotomy to make sure the tumors are resected with a negative margin, i.e. that the tumor is surrounded completely by a margin of non-cancerous tissue, and that arteries and airways to portions of the lung that are not being removed are preserved intact. In addition, patients who have had pre-operative chemotherapy or radiation for lung cancer or previous chest surgeries may not be candidates for VATS due to scarring around the major blood vessels that makes dissection via VATS difficult. Cases in which a lung tumor invades the chest wall and an en bloc resection of ribs must be performed to achieve negative resection margins generally are felt to abrogate the value of VATS. Finally, pneumonectomy by VATS, though it has been reported, is generally not performed because the size of the specimen requires a large incision with or without rib spreading for removal, abrogating the value of VATS.

Children with RTT need to engage and participate in leisure activities just like typically developing children. Play is the primary activity of childhood, and is considered both a form of leisure and productivity. It is essential to development as it facilitates cognitive, physical, social, and emotional well-being. Play is an activity with multiple purposes; it provides opportunities for a child to grow and develop, explore, learn, build relationships, and develop interests. Because play is so central to a child's development, therapists try to find ways that allow these children to play. The support team, including the special education teacher, OT, PT, and speech pathologist, work with clients and their family to make sure that the interventions focus on play activities that are meaningful to the child, whether it be arts, music, sports, computer games, and/or maintaining social relationships.

Fundamentally novel approaches for model choice that incorporate quality control as an integral step in the process have recently been proposed. ABC allows, by construction, estimation of the discrepancies between the observed data and the model predictions, with respect to a comprehensive set of statistics. These statistics are not necessarily the same as those used in the acceptance criterion. The resulting discrepancy distributions have been used for selecting models that are in agreement with many aspects of the data simultaneously, and model inconsistency is detected from conflicting and co-dependent summaries. Another quality-control-based method for model selection employs ABC to approximate the effective number of model parameters and the deviance of the posterior predictive distributions of summaries and parameters. The deviance information criterion is then used as measure of model fit. It has also been shown that the models preferred based on this criterion can conflict with those supported by Bayes factors. For this reason, it is useful to combine different methods for model selection to obtain correct conclusions.

Livermorium is a synthetic chemical element with the symbol Lv and has an atomic number of 116. It is an extremely radioactive element that has only been created in a laboratory setting and has not been observed in nature. The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the Joint Institute for Nuclear Research (JINR) in Dubna, Russia to discover livermorium during experiments conducted between 2000 and 2006. The name of the laboratory refers to the city of Livermore, California, where it is located, which in turn was named after the rancher and landowner Robert Livermore. The name was adopted by IUPAC on May 30, 2012. Four isotopes of livermorium are known, with mass numbers between 290 and 293 inclusive; the longest-lived among them is livermorium-293 with a half-life of about 60 milliseconds. A fifth possible isotope with mass number 294 has been reported but not yet confirmed.

Better establishing tourism and urban behaviour in areas that have population of rhesus macaques as means to facilitate better relationship. In areas of tourism human behaviour is necessary to prevent conflict. One method of this is to introduce public education programs as well as  restrict visitors to specific viewing platforms, with the goal to minimize physical proximity. An important aspect is enforcing no feed regulations that only allow provisioning to be performed by trained staff at scheduled times. Regulating visitor behaviours that provoke aggressive responses from macaques, including noise regulation greatly benefits conflict reduction. Replacing food conditioned behaviours established by human visitors and further human education will greatly aid in returning co-existence between rhesus macaques and humans.

In 2006, Xcel Energy proposed a series of upgrades to the plant in order to increase its output and extend its life for an additional 20 years. In December 2013, the Nuclear Regulatory Commission approved the license amendment allowing the unit to increase output from 600 MWe to 671 MWe However, final project implementation costs significantly outstripped initial estimates by more than $400 million. In 2015, the Minnesota Public Utilities Commission denied full cost recovery and determined that, while Xcel Energy could include the additional cost in customer rates, it could not earn a return on those costs. Xcel Energy would record a greater than $100 million loss in 1Q 2015 as a result and recouped $27 million less than expected from the project.

The second generation of the FIA technique, called sequential injection analysis (SIA), was conceived in 1990 by Ruzicka and Marshal, and has been further developed and miniaturized over the course of the following decade. It uses flow programming instead of the continuous flow regime (as used by CFA and FIA), that allows the flow rate and flow direction to be tailored to the need of individual steps of analytical protocol. Reactants are mixed by flow reversals and a measurement is carried out while the reaction mixture is arrested within the detector by stopping the flow. Microminiaturized chromatography is carried out on microcolumns that are automatically renewed by microfluidic manipulations. The discrete pumping and metering of microliter sample and reagent volumes used in SI only generates waste per each sample injection. The enormous volume of FI and SI literature documents the versatility of FI and SI and their usefulness for routine assays (in soil, water, environmental, biochemical and biotechnological assays) has demonstrated their potential to be used as a versatile research tool.

The first cinema feature movie to make extensive use of solid 3D CGI was Walt Disney's "Tron", directed by Steven Lisberger, in 1982. The film is celebrated as a milestone in the industry, though less than twenty minutes of this animation were actually used—mainly the scenes that show digital "terrain", or include vehicles such as "Light Cycles", tanks and ships. To create the CGI scenes, Disney turned to the four leading computer graphics firms of the day: Information International Inc, Robert Abel and Associates (both in California), MAGI, and Digital Effects (both in New York). Each worked on a separate aspect of the movie, without any particular collaboration. "Tron" was a box office success, grossing $33 million on a budget of $17 million.

As the eighteenth century came to a close, human understanding of electrostatics approached maturity. Benjamin Franklin had already established the notion of electric charge and the conservation of charge; Charles-Augustin de Coulomb had enunciated his inverse-square law of electrostatics. In 1777, Joseph-Louis Lagrange introduced the concept of a potential function that can be used to compute the gravitational force of an extended body. In 1812, Poisson adopted this idea and obtained the appropriate expression for electricity, which relates the potential function formula_13 to the electric charge density formula_14. Poisson's work on potential theory inspired George Green's 1828 paper, "An Essay on the Application of Mathematical Analysis to the Theories of Electricity and Magnetism".

The Weyl spinors transform under the action of the spin group formula_76. The complexification of the spin group, called the spinc group formula_77, is a product formula_78 of the spin group with the circle formula_79 with the product formula_80 just a notational device to identify formula_81 with formula_82 The geometric point of this is that it disentangles the real spinor, which is covariant under Lorentz transformations, from the formula_83 component, which can be identified with the formula_83 fiber of the electromagnetic interaction. The formula_80 is entangling parity and charge conjugation in a manner suitable for relating the Dirac particle/anti-particle states (equivalently, the chiral states in the Weyl basis). The bispinor, insofar as it has linearly independent left and right components, can interact with the electromagnetic field. This is in contrast to the Majorana spinor and the ELKO spinor, which cannot ("i.e." they are electrically neutral), as they explicitly constrain the spinor so as to not interact with the formula_86 part coming from the complexification.

The 8th was shifted 1 June 1999 to XV Corps for the Kargil conflict, taking over vacant positions formerly held by 28th Mountain Division. The division under command of Major General Mohinder Puri moved north to take over the Dras-Mushkoh sector in the Kargil District. It augmented the beleaguered 3rd Infantry Division, which was based in Leh. The soldiers had to face the twin challenges of being moved to a high altitude environment and a frigid climate, without the benefit of acclimatization and adequate winter supplies. Following initial reversals, units from the division went on to dislodge the Pakistani infiltrators and capture back Indian territories by using the strategy of preliminary artillery bombardment, followed by climbing near-vertical cliffs during night time in high altitude, multi-directional attacks with overwhelming force and close combat. Prominent battles fought by the division during the war include Battle of Tololing, Battle of Point 5140, Battle of Black Rock, Battle of Point 4700, Battle of Tiger Hill, Battle of Point 4875 (Gun Hill) and the capture of Twin Bumps.

SELCO India eventually came into being in 1995 under the leadership of Hande and Neville Williams, president of Solar Electric Light Fund (SELF). Financial backing was received in December 1996 from Winrock International which released a conditional loan of $150,000 under the USAID Renewable energy commercialization project. This was however on a condition that SELCO INDIA created couple of solar service centers and install a minimum number of systems. SELCO started with a financial model in which each customer would pay 25% of the cost upfront as down payment and will further pay a monthly installment which is affordable and within the average monthly budget of a family in the region. Along with this, the SELCO INDIA also provided a year's guarantee to the warranty of the manufacturer along with free service for a year and a 90-day money back guarantee. The loan to Winrock was paid back by 2000.

There is significant interest in SiNWs for their unique properties and the ability to control size and aspect ratio with great accuracy. As yet, limitations in large-scale fabrication impede the uptake of this material in the full range of investigated applications. Combined studies of synthesis methods, oxidation kinetics and properties of SiNW systems aim to overcome the present limitations and facilitate the implementation of SiNW systems, for example, high quality vapor-liquid-solid–grown SiNWs with smooth surfaces can be reversibly stretched with 10% or more elastic strain, approaching the theoretical elastic limit of silicon, which could open the doors for the emerging “elastic strain engineering” and flexible bio-/nano-electronics.

Peaty first joined Dove Valley Swimming Club in Uttoxeter when he was nine, and started to win races and setting club records by the time he was twelve. When he was 14, a friend took Peaty to join City of Derby Swimming Club, but the coach at the club, former Olympic swimmer Melanie Marshall, was not impressed by Peaty's performance in the freestyle and put him in the slow lane with younger girls. However, she noticed "something special" the first time she saw him swim breaststroke. She also recognised the advantages of his large hands, big feet, "extraordinary cardiovascular system", and hyper-mobile, double-jointed knees and ankles. According to Peaty, he did not take swimming seriously until he was 17 – he was preparing for a night out drinking with friends when he read that Craig Benson, whom he knew well from the junior circuit, made the semi-final of the 100m breaststroke at the 2012 London Olympics. This prompted him to reassess his priorities, and spurred him on to commit fully to swimming and train full-time.

Verdi conducted his Requiem in Paris, London and Vienna in 1875 and in Cologne in 1876. It seemed that it would be his last work. In the words of his biographer John Rosselli, it "confirmed him as the unique presiding genius of Italian music. No fellow composer...came near him in popularity or reputation". Verdi, now in his sixties, initially seemed to withdraw into retirement. He deliberately shied away from opportunities to publicise himself or to become involved with new productions of his works, but secretly he began work on "Otello", which Boito (to whom the composer had been reconciled by Ricordi) had proposed to him privately in 1879. The composition was delayed by a revision of "Simon Boccanegra" which Verdi undertook with Boito, produced in 1881, and a revision of "Don Carlos". Even when "Otello" was virtually completed, Verdi teased "Shall I finish it? Shall I have it performed? Hard to tell, even for me." As news leaked out, Verdi was pressed by opera houses across Europe with enquiries; eventually the opera was triumphantly premiered at La Scala in February 1887.

with the nearest-neighbor (π orbitals) hopping energy "γ" ≈ and the lattice constant . The conduction and valence bands, respectively, correspond to the different signs. With one "p" electron per atom in this model the valence band is fully occupied, while the conduction band is vacant. The two bands touch at the zone corners (the "K" point in the Brillouin zone), where there is a zero density of states but no band gap. The graphene sheet thus displays a semimetallic (or zero-gap semiconductor) character, although the same cannot be said of a graphene sheet rolled into a carbon nanotube, due to its curvature. Two of the six Dirac points are independent, while the rest are equivalent by symmetry. In the vicinity of the "K"-points the energy depends "linearly" on the wave vector, similar to a relativistic particle. Since an elementary cell of the lattice has a basis of two atoms, the wave function has an effective 2-spinor structure.

The Department of State insists that ITAR has limited effect and provides a security benefit to the nation that outweighs any impact that these sectors must bear. Every year, the Department of State can cite multiple arrests of ITAR violators by U.S. Immigration and Customs Enforcement agents and the FBI. It is apparent that companies and institutions within the affected areas are somewhat stifled by ITAR regulations, in addition to the trade the U.S. economy would receive, and the science technology that it would share, notwithstanding that its restrictions encourage U.S. allies (such as Australia and the UK) to procure defense equipment from other sources that may not be interoperable with U.S. equipment. Companies argue that ITAR is a significant trade barrier that acts as a substantial negative subsidy, weakening U.S. industries' ability to compete. U.S. companies point to announcements in Europe by TAS (Thales Alenia Space) promoting their "ITAR-free" telecommunication satellites.

The reluctance of insurance organizations to pay for the HDC/BMT treatment stemmed from the difference in patients'/doctors' and researchers' opinions of the treatment. Academic researchers wanted to wait for the results of the clinical trials, while breast cancer oncologists and bone marrow transplanters supported the procedure. At the time, the clinical trials on the effectiveness and benefits of this treatment diverged greatly: the trials by Peters in the U.S. and other large research hospitals in Europe reached the conclusion that the treatment had at most modest results—even negative results—regarding the superiority of this high-dose chemotherapy with autologous bone marrow transplant. However, a study by the researcher Werner Bezwoda showed promising benefits of this treatment—although his study was later confirmed to have falsified data. In addition, there was already a lot of positive publicity surrounding the treatment, and 79% of oncologists believed that HDC/BMT was an appropriate treatment for women with locally advanced breast cancer. In fact, the number of women who received this treatment increased by about 8000 between 1990 and 1999. This disparity was one of the reasons HMOs held back from covering high-dose chemotherapy with autologous bone marrow transplant; if a treatment is expensive and not clinically proven to be beneficial, health organizations can decline to pay for the treatment, regardless of patient protests.

The main change in terms of chip size was the elimination of the tri-state drivers from the address bus outputs. This had been included in the 6800 to allow it to work with other chips in direct memory access (DMA) and co-processing roles, at the cost of significant die space. In practice, using such a system required the other devices to be similarly complex, and designers instead tended to use off-chip systems to coordinate such access. The 6502 simply removed this feature, in keeping with its design as an inexpensive controller being used for specific tasks and communicating with simple devices. Peddle suggested that anyone that actually required this style of access could implement it with a single 74158.

As well as manipulating the DNA, techniques had to be developed for its insertion (known as transformation) into an organism's genome. Griffiths experiment had already shown that some bacteria had the ability to naturally take up and express foreign DNA. Artificial competence was induced in "Escherichia coli" in 1970 when Morton Mandel and Akiko Higa showed that it could take up bacteriophage λ after treatment with calcium chloride solution (CaCl). Two years later, Stanley Cohen showed that CaCl treatment was also effective for uptake of plasmid DNA. Transformation using electroporation was developed in the late 1980s, increasing the efficiency and bacterial range. In 1907 a bacterium that caused plant tumors, "Agrobacterium tumefaciens", was discovered and in the early 1970s the tumor inducing agent was found to be a DNA plasmid called the Ti plasmid. By removing the genes in the plasmid that caused the tumor and adding in novel genes researchers were able to infect plants with "A. tumefaciens" and let the bacteria insert their chosen DNA into the genomes of the plants.

There have been follow-ups on the claims that this force can be produced in a full vacuum, meaning it is an unknown anti-gravity force, and not just the more well known ion wind. As part of a study in 1990, U.S. Air Force researcher R. L. Talley conducted a test on a Biefeld–Brown-style capacitor to replicate the effect in a vacuum. Despite attempts that increased the driving DC voltage to about 19 kV in vacuum chambers up to 10 torr, Talley observed no thrust in terms of static DC potential applied to the electrodes. In 2003, NASA scientist Jonathan Campbell tested a lifter in a vacuum at 10 torr with a voltage of up to 50 kV, only to observe no movement from the lifter. Campbell pointed out to a Wired magazine reporter that creating a true vacuum similar to space for the test requires tens of thousands of dollars in equipment.

In this world, alchemy is one of the most-practiced sciences; alchemists who work for the government are known as and are automatically given the rank of major in the military. Alchemists have the ability, with the help of patterns called transmutation circles, to create almost anything they desire. However, when they do so, they must provide something of equal value in accordance with the Law of Equivalent Exchange. The only things alchemists are forbidden from transmuting are humans and gold. There has never been a successful human transmutation; those who attempt it lose a part of their body, and the result is an inhuman mass. Attemptees are confronted by , a pantheistic and semi-cerebral God-like being who tauntingly regulates all alchemy use, and whose nigh-featureless appearance is relative to the person with whom Truth converses; it is frequently claimed and believed that Truth is a personal God who punishes the arrogant.

An ECAL/BDA abort was similar to RTLS, but instead of landing at the Kennedy Space Center, the orbiter would attempt to land at another site along the east coast of North America (in the case of ECAL) or Bermuda (in the case of BDA). Various potential ECAL landing sites extended from South Carolina into Newfoundland, Canada. The designated landing site in Bermuda was Naval Air Station Bermuda (a United States Navy facility). ECAL/BDA was a contingency abort that was less desirable than an intact abort, primarily because there was so little time to choose the landing site and prepare for the orbiter's arrival. All of the pre-designated sites were either military airfields or joint civil/military facilities. ECAL emergency sites were not as well equipped to accommodate an orbiter landing as those prepared for RTLS and TAL aborts. The sites were not staffed with NASA employees or contractors and the staff working there were given no special training to handle a shuttle landing. If they were ever needed, the shuttle pilots would have had to rely on regular air traffic control personnel using procedures similar to those used to land a gliding aircraft that has suffered complete engine failure.

The earlier ETCS specification contained a lot of optional elements that limited interoperability. The "Class 1" specifications were revised in the following year leading to "SRS 2.3.0" document series that was made mandatory by the "European Commission" in decision 2007/153/EEC on 9 March 2007. Annex A describes the technical specifications on interoperability for high-speed (HS) and conventional rail (CR) transport. Using "SRS 2.3.0" a number of railway operators started to deploy ETCS on a large scale, for example the Italian Sistema Controllo Marcia Treno (SCMT) is based on Level 1 balises. Further development concentrated on compatibility specification with the earlier "Class B" systems leading to specifications like EuroZUB that continued to use the national rail management on top of Eurobalises for a transitional period. Following the experience in railway operation the European Union Agency for Railways (ERA) published a revised specification "Class 1" "SRS 2.3.0d" ("debugged") that was accepted by the European Commission in April 2008.

Usually one, or more commonly two, substantial projects are to be completed in the fourth year which may well have research elements. At the end of the second or third years, there is usually a threshold of academic performance in examinations to be reached to allow progression into the final year. Final results are, in most cases, awarded on the standard British undergraduate degree classification scale, although some universities award something structurally similar to 'Distinction', 'Merit', 'Pass' or 'Fail', as this is often the way that taught postgraduate master's degrees are classified.

Also in 1947 the Oriental Institute's Jarmo Project in Iraq was launched by Braidwood. It was an early example of an excavation aiming to retrieve evidence of the methods of early food production and to solve the ecological problem of its origin and early consequences. The project brought together archaeologists, biologists, and geologists in a ground-breaking study which earned it a National Science Foundation grant in 1954 — one of the first times such an award had been made to an anthropological project. When the political situation in Iraq deteriorated, however, Braidwood was forced to leave, and he went on to carry out similar projects in Iran and Turkey.

For particles with the mass of a proton or greater, elastic scattering is one of the main methods by which the particles interact with matter. At relativistic energies, protons, neutrons, helium ions, and HZE ions will undergo numerous elastic collisions before they are dissipated. This is a major concern with many types of ionizing radiation, including galactic cosmic rays, solar proton events, free neutrons in nuclear weapon design and nuclear reactor design, spaceship design, and the study of the earth's magnetic field. In designing an effective biological shield, proper attention must be made to the linear energy transfer of the particles as they propagate through the shield. In nuclear reactors, the neutron's mean free path is critical as it undergoes elastic scattering on its way to becoming a slow-moving thermal neutron.

When a collection system is used, the offgas must be cooled to condense the bulk of the volatilized components into a liquid. The offgas will exit most desorbers in the 350–900 °F range. The offgas is then typically cooled to somewhere between 120 and 40 °F to condense the bulk of the volatilized water and organic contaminants. Even at 40 °F, there may be measurable amounts of non-condensed organics. For this reason, after the condensation step, further treatment of the offgas is usually required. The cooled offgas may be treated by carbon adsorption, or thermal oxidation. Thermal oxidation can be accomplished using a catalytic oxidizer, an afterburner or by routing the offgas to the combustion heat source for the desorber. The volume of gas requiring treatment for indirect fired desorbers is a fraction of that required for a direct fired desorber. This requires smaller air pollution control trains for the gaseous process vent emissions. Some thermal desorption systems recycle the carrier gas, thereby further reducing the volume of gaseous emissions.

The reasons for microencapsulation are numerous. It is mainly used to increase the stability and life of the product being encapsulated, facilitate the manipulation of the product and provide for the controlled release of the contents. In some cases, the core must be isolated from its surroundings, as in isolating vitamins from the deteriorating effects of oxygen, retarding evaporation of a volatile core, improving the handling properties of a sticky material, or isolating a reactive core from chemical attack. In other cases, the objective is not to isolate the core completely but to control the rate at which it releases the contents, as in the controlled-release of drugs or pesticides. The problem may be as simple as masking the taste or odor of the core, or as complex as increasing the selectivity of an adsorption or extraction process. In environmental science, a pesticide may be microencapsulated to minimize leaching or volatilization risks. Even microencapsulated self-healing agent has proven applications in designing of self-healing polymer coatings.

A horizontal mill has the same sort but the cutters are mounted on a horizontal spindle, or arbor, mounted across the table. Many horizontal mills also feature a built-in rotary table that allows milling at various angles; this feature is called a "universal table". While endmills and the other types of tools available to a vertical mill may be used in a horizontal mill, their real advantage lies in arbor-mounted cutters, called side and face mills, which have a cross section rather like a circular saw, but are generally wider and smaller in diameter. Because the cutters have good support from the arbor and have a larger cross-sectional area than an end mill, quite heavy cuts can be taken enabling rapid material removal rates. These are used to mill grooves and slots. Plain mills are used to shape flat surfaces. Several cutters may be ganged together on the arbor to mill a complex shape of slots and planes. Special cutters can also cut grooves, bevels, radii, or indeed any section desired. These specialty cutters tend to be expensive. Simplex mills have one spindle, and duplex mills have two. It is also easier to cut gears on a horizontal mill. Some horizontal milling machines are equipped with a power-take-off provision on the table. This allows the table feed to be synchronized to a rotary fixture, enabling the milling of spiral features such as hypoid gears.

The radio continuum emission along the galaxy's major axis is asymmetrical, being brighter in the southwestern part than in the northeast. But the overall radio surface brightness is on the low side. In the mid-infrared range, the spectrum shows indications of high ionization levels usually associated with an active galactic nucleus. However, optical observations show no signs of an active nucleus, which may just mean it is heavily obscured. Indeed, the amount of ionized matter appears to increase near the core. Although this galaxy lacks a bulge that could supply mass to a supermassive black hole, a large black hole was detected at the core by the Chandra X-ray Observatory in 2012. It is inferred to have a mass of around 10 to 10 times the mass of the Sun. This makes it one of the lowest mass nuclear black holes known.

Columbanus did not lead a perfect life. According to Jonas and other sources, he could be impetuous and even headstrong, for by nature he was eager, passionate, and dauntless. These qualities were both the source of his power and the cause of his mistakes. His virtues, however, were quite remarkable. Like many saints, he had a great love for God's creatures. Stories claim that as he walked in the woods, it was not uncommon for birds to land on his shoulders to be caressed, or for squirrels to run down from the trees and nestle in the folds of his cowl. Although a strong defender of Irish traditions, he never wavered in showing deep respect for the Holy See as the supreme authority. His influence in Europe was due to the conversions he effected and to the rule that he composed. It may be that the example and success of Columba in Caledonia inspired him to similar exertions. The life of Columbanus stands as the prototype of missionary activity in Europe, followed by such men as Kilian, Vergilius of Salzburg, Donatus of Fiesole, Wilfrid, Willibrord, Suitbert of Kaiserwerdt, Boniface, and Ursicinus of Saint-Ursanne.

The primary aim of the experiment is to make a precise measurement of the individual neutrino fluxes from the Sun and compare them to the Standard solar model predictions. This will allow scientists to test and to further understand the functioning of the Sun (e.g., nuclear fusion processes taking place at the core of the Sun, solar composition, opacity, matter distribution, etc.) and will also help determine properties of neutrino oscillations, including the MSW effect. Specific goals of the experiment are to detect beryllium-7, boron-8, pp, pep and CNO solar neutrinos as well as anti-neutrinos from the Earth and nuclear power plants. The project may also be able to detect neutrinos from supernovae within our galaxy with a special potential to detect the elastic scattering of neutrinos onto protons, due to neutral current interactions. Borexino is a member of the Supernova Early Warning System. Searches for rare processes and potential unknown particles are also underway.

In 1956, Paul Kuroda of the University of Arkansas postulated that a natural fission reactor may have once existed. Since nuclear chain reactions may only require natural materials (such as water and uranium, if the uranium has sufficient amounts of U), it was possible to have these chain reactions occur in the distant past when uranium-235 concentrations were higher than today, and where there was the right combination of materials within the Earth's crust. made up a larger share of uranium on earth in the geological past due to the different half life of the isotopes and , the former decaying almost an order of magnitude faster than the latter. Kuroda's prediction was verified with the discovery of evidence of natural self-sustaining nuclear chain reactions in the past at Oklo in Gabon in September 1972. To sustain a nuclear fission chain reaction at present isotope ratios in natural uranium on earth would require the presence of a neutron moderator like heavy water or high purity carbon (e.g. graphite) in the absence of neutron poisons, which is even more unlikely to arise by natural geological processes than the conditions at Oklo some two billion years ago.

The best-known removable retainer is the Hawley retainer, which consists of a metal wire that typically surrounds the six anterior teeth and keeps them in place. Hawley retainers are one of the oldest types of removable retainers. Named for its inventor, Dr. Charles A. Hawley, the labial wire, or Hawley bow, incorporates 2 omega loops for adjustment. It is anchored in an acrylic baseplate that sits in the palate (roof of the mouth). They are made from metal wire running along the outside of the teeth. There are many adaptations possible with Hawley retainers. The advantage of this type of retainer is that the metal wires can be adjusted to finish treatment and continue minor movement of the anterior teeth as needed. It also benefits from being robust and rigid, easy to construct and allows prosthetic tooth/teeth to be added onto with metal stops placed mesial and distal to the prosthetic teeth to prevent any relapse. To help fix rotations; acrylic facing can be added to the labial bow and a bite plane added to maintain the result of deep overbite correction. Also, to control the position of the canine, reverse U-loop can be employed. Additionally, to avoid occlusal interferences, the labial bow can be soldered to the cribs.

The silver cluster-leaf grows to a height of about in woodland but isolated trees can be up to tall. The bark is a reddish or greyish brown colour and peels away in strips. The bluish-green leaves tend to be clustered at the tips of the branches. They are ovate with entire margins and both the upper and lower surfaces are clothed in silvery hairs. The flowers are white and are borne in short axilliary spikes. They have an unpleasant smell and may be pollinated by flies. The fruit are winged nuts containing a single seed and turn a darker pink colour as they ripen. They may remain attached to the branch for a year and are dispersed by the wind. They sometimes become contorted and hairy as a result of the activities of parasitic insect larvae.

Early on, IAI decided to adopt a delta wing configuration, of which the company was already familiar with through its work on the earlier Kfir, which was paired with large, steerable canards situated forward of the wing. The delta wing arrangement was relatively low-weight, provided space for considerable fuel capacity, a smooth low-altitude fight attitude, and high levels of directional stability while flown at high angles of attack (AOA). The canard generated additional lift and positive control when at high AOAs. While this configuration afforded excellent maneuverability, it also exhibited natural instability during flight. To compensate, the Lavi was fitted with a sophisticated digital fly-by-wire system which allowed the aircraft to take advantage of this particular wing design while eliminating this shortcoming. The Lavi was one of the first aircraft to feature this type of configuration, which has since become more commonplace amongst fighter aircraft.

There is good mathematics; there is bad mathematics. There are mathematicians who are totally uninterested in science, who are building tools that science will find indispensable. There are mathematicians passionately interested in science, and building tools for specific use there, whose work will become as obsolete as the Zeppelin or the electronic valve. The path from discovery to utility is a rabbit-warren of false ends: mathematics for its own sake has had, and wil continue to have, its place in the scheme of things. And, after all, the isolation of the topologist who knows no physics is no worse than that of the physicist who knows no topology. Today's science requires specialization from its individuals: the collective activity of scientists as a whole is where the links are forged. If only Morris Kline showed some inkling of the nature of this process, I would take his arguments more seriously. But his claim that mathematics has gone into decline is one based too much on ignorance, and his arguments are tawdry in comparison to the marvellous, shining vigour of today's mathematics. I too would like to see more overt recognition by mathematicians of the importance of scientific problems; but to miss the fact that they do splendid work even in this apparent isolation is to lose the battle before it has begun.

Most birds have approximately 175 different muscles, mainly controlling the wings, skin, and legs. Overall, the muscle mass of birds is concentrated ventrally. The largest muscles in the bird are the pectorals, or the pectoralis major, which control the wings and make up about 15–25% of a flighted bird's body weight. They provide the powerful wing stroke essential for flight. The muscle deep to (underneath) the pectorals is the supracoracoideus, or the pectoralis minor. It raises the wing between wingbeats. Both muscle groups attach to the keel of the sternum. This is remarkable, because other vertebrates have the muscles to raise the upper limbs generally attached to areas on the back of the spine. The supracoracoideus and the pectorals together make up about 25–40% of the bird's full body weight. Caudal to the pectorals and supracoracoides are the internal and external obliques which compress the abdomen. Additionally, there are other abdominal muscles present that expand and contract the chest, and hold the ribcage. The muscles of the wing, as seen in the labelled images, function mainly in extending or flexing the elbow, moving the wing as a whole or in extending or flexing particular digits. These muscles work to adjust the wings for flight and all other actions. Muscle composition does vary between species and even within families.

Although the P versus NP problem was formally defined in 1971, there were previous inklings of the problems involved, the difficulty of proof, and the potential consequences. In 1955, mathematician John Nash wrote a letter to the NSA, in which he speculated that cracking a sufficiently complex code would require time exponential in the length of the key. If proved (and Nash was suitably skeptical), this would imply what is now called P ≠ NP, since a proposed key can easily be verified in polynomial time. Another mention of the underlying problem occurred in a 1956 letter written by Kurt Gödel to John von Neumann. Gödel asked whether theorem-proving (now known to be co-NP-complete) could be solved in quadratic or linear time, and pointed out one of the most important consequences – that if so, then the discovery of mathematical proofs could be automated.

In the United States, Enigma machines can be seen at the Computer History Museum in Mountain View, California, and at the National Security Agency's National Cryptologic Museum in Fort Meade, Maryland, where visitors can try their hand at enciphering and deciphering messages. Two machines that were acquired after the capture of during World War II are on display alongside the submarine at the Museum of Science and Industry in Chicago, Illinois. A three-rotor Enigma is on display at Discovery Park of America in Union City, Tennessee. A four-rotor device is on display in the ANZUS Corridor of the Pentagon on the second floor, A ring, between corridors 8 and 9. This machine is on loan from Australia. The United States Air Force Academy in Colorado Springs has a machine on display in the Computer Science Department. There is also a machine located at The National WWII Museum in New Orleans. The International Museum of World War II near Boston has seven Enigma machines on display, including a U-Boat four-rotor model, one of three surviving examples of an Enigma machine with a printer, one of fewer than ten surviving ten-rotor code machines, an example blown up by a retreating German Army unit, and two three-rotor Enigmas that visitors can operate to encode and decode messages. Computer Museum of America in Roswell, Georgia has a three-rotor model with two additional rotors. The machine is fully restored and CMoA has the original paperwork for the purchase on 7 March 1936 by the German Army. The National Museum of Computing also contains surviving Enigma machines in Bletchley, England.

Undiagnosed hearing loss in a child can have serious effects on many developmental areas, including language, social interactions, emotions, cognitive ability, academic performance and vocational skills, any combination of which can have negative impacts on the quality of life. The serious impacts of a late diagnosis, combined with the high incidence (estimated at 1 - 3 per 1000 live births, and as high as 4% for neonatal intensive care unit patients) have been the driving forces behind screening programs designed to identify infants with hearing loss as early as possible. Early identification allows these patients and their families to access the necessary resources to help them maximize their developmental outcomes.

A number of individual genes have been identified as influencing variations in life span within a population of organisms. The effects of these genes is strongly dependent on the environment, in particular, on the organism's diet. Caloric restriction reproducibly results in extended lifespan in a variety of organisms, likely via nutrient sensing pathways and decreased metabolic rate. The molecular mechanisms by which such restriction results in lengthened lifespan are as yet unclear (see for some discussion); however, the behavior of many genes known to be involved in DNA repair is altered under conditions of caloric restriction. Several agents reported to have anti-aging properties have been shown to attenuate constitutive level of mTOR signaling, an evidence of reduction of metabolic activity, and concurrently to reduce constitutive level of DNA damage induced by endogenously generated reactive oxygen species.

1-Methyl-4-phenyl-1,2,3,6-tetraydropyridine (MPTP) is a widely used neurotoxin in Parkinson's disease research (Figure 4). In contrast to 6-OHDA, MPTP crosses the BBB which making the neurotoxin even more selective for dopaminergic neurons. Due to the ability to cross the blood-brain-barrier, MPTP is administered peripherally, subcutaneously. This neurotoxin is known to replicate oxidative stress, ROS, energy failure, and inflammation; which are all hallmarks in Parkinson's disease. However, it does not produce Lewy body pathology. The mechanism of action of MPTP is due to its conversion to 1-methyl-4-phenylpyridinium (MPP) caused by the interaction of MPTP with monoamine oxidase B (MAO-B). (Figure5). MPTP enters astrocytes and is metabolized to MPP before being released. Once released into the extracellular space, MPP is taken up into the neuron by DAT and is stored in vesicles by the up take of vesicular monoamine transporter (VMAT2). In the neuron, MPP inhibits the function of complex 1 of electron transport chain, which decreases ATP production and releases ROS.

The sharp-shinned hawk is sometimes separated into four species, with the northern group ("see distribution") retaining both the scientific name and the common name: sharp-shinned hawk ("A. striatus"). In addition to the nominate taxon ("A. s. striatus"), it includes subspecies "perobscurus", "velox", "suttoni", "madrensis", "fringilloides", and "venator". The three remaining taxa, each considered a monotypic species if split, are the white-breasted hawk ("A. chionogaster"; Kaup, 1852), plain-breasted hawk ("A. ventralis"; Sclater, 1866) and rufous-thighed hawk ("A. erythronemius"; Kaup, 1850). The breeding ranges of the groups are entirely allopatric, although the wintering range of the nominate group partially overlaps with the range of "chionogaster" (as is also the case with certain taxa within the nominate group). This allopatry combined with differences in plumage ("see appearance") and, apparently, certain measurements, has been the background for the split, but hard scientific data are presently lacking (AOU). Disregarding field guides, most material published in recent years (e.g. AOU, Ferguson-Lees "et al." p. 586, and Dickinson "et al.") has therefore considered all to be members of a single widespread species – but not without equivocation: Ferguson-Lees et al. say that if they were to make a world list, they would include the three taxa as separate species (p. 75), and the AOU's comment includes the note "split almost certainly good".

All living conifers are woody plants, and most are trees, the majority having monopodial growth form (a single, straight trunk with side branches) with strong apical dominance. Many conifers have distinctly scented resin, secreted to protect the tree against insect infestation and fungal infection of wounds. Fossilized resin hardens into amber. The size of mature conifers varies from less than one metre, to over 100 metres. The world's tallest, thickest, largest, and oldest living trees are all conifers. The tallest is a Coast Redwood ("Sequoia sempervirens"), with a height of 115.55 metres (although one Victorian mountain ash, "Eucalyptus regnans", allegedly grew to a height of 140 metres, although the exact dimensions were not confirmed). The thickest, meaning the tree with the greatest trunk diameter, is a Montezuma Cypress ("Taxodium mucronatum"), 11.42 metres in diameter. The largest tree by three-dimensional volume is a Giant Sequoia ("Sequoiadendron giganteum"), with a volume 1486.9 cubic metres. The smallest is the pygmy pine ("Lepidothamnus laxifolius") of New Zealand, which is seldom taller than 30 cm when mature. The oldest is a Great Basin Bristlecone Pine ("Pinus longaeva"), 4,700 years old.

The earliest phases of the Big Bang are subject to much speculation, since astronomical data about them are not available. In the most common models the universe was filled homogeneously and isotropically with a very high energy density and huge temperatures and pressures, and was very rapidly expanding and cooling. The period from 0 to 10 seconds into the expansion, the Planck epoch, was a phase in which the four fundamental forces — the electromagnetic force, the strong nuclear force, the weak nuclear force, and the gravitational force, were unified as one. In this stage, the characteristic scale length of the universe was the Planck length, , and consequently had a temperature of approximately 10 degrees Celsius. Even the very concept of a particle breaks down in these conditions. A proper understanding of this period awaits the development of a theory of quantum gravity. The Planck epoch was succeeded by the grand unification epoch beginning at 10 seconds, where gravitation separated from the other forces as the universe's temperature fell.

Sigala et al. found that solvent exclusion and replacement by the remote hydrophobic steroid rings negligibly alter the electrostatic environment within the KSI oxyanion hole. In addition, ligand binding does not grossly alter the conformations of backbone and side chain groups observed in X-ray structures of PI KSI. However, NMR and UV studies suggest that steroid binding restricts the motions of several active-site groups, including Tyr-16. Recently, the Herschlag group proposed that remote binding of hydrophobic regions of the substrate to distal portions of the active site contribute to KSI catalysis (>5 kcal/mol). A 4-ring substrate reacted 27,000 times faster than a single ring substrate indicating the importance of distal active site binding motifs. This activity ratio persists throughout mutagenesis of residues important to oxyanion hole stabilization, implying that distal binding is what accounts for the large aforementioned reactivity difference.

It is currently hypothesized that long range chemorepulsion involves initiation of the Arachidonic acid pathway upon netrin-1 interaction with the DCC/UNC-5 complex. This pathway increases the intracellular levels of 12-HPETE (12-Hydroperoxy-5, 8, 10, 14-Eicosatetraenoic Acid), which induces cGMP signaling and subsequently causes a decrease in the cAMP/cGMP ratio. Reducing this ratio inhibits calcium conductance through the L-type calcium channels (LCC) and ultimately results in growth cone repulsion though a possible activation of Ras homolog gene family, member A (RhoA). A similar RhoA-mediated mechanism is proposed for short range chemorepulsion whereby netrin-1 binding to UNC-5 homodimers alone induces tyrosine phosphorylation requiring FAK and Src, which as a result activates RhoA. An additional mechanism proposes that binding of the tyrosine phosphatase Shp2 to the netrin-1/UNC-5 complex may also trigger chemorepulsion through RhoA.

Despite anisomycin's wide usage as a protein synthesis inhibitor, there have been a lot of studies centered on the biosynthesis of anisomycin. One study by Butler in 1974 proposed possible precursors to this natural product. Fermentation of Streptomyces with labeled amino acids was followed by a degradation of the radioactive anisomycin and deacetylanisomycin products to determine the locations of the labeled carbons. Although its pyrrolidine-based structure suggests that it is derived from proline, the results from the experiments indicated that tyrosine, glycine, methionine, and acetate are the primary precursors for the biosynthesis of anisomycin. Tyrosine and, to a limited degree, phenylalanine, contribute to C-2 of the pyrrolidine ring. Methionine is likely responsible for the methylation of the hydroxyl group on the aromatic ring as S-adenosylmethionine (SAM). Glycine or acetate account for C-4 and C-5 on the pyrrolidine ring. It was noted that deacetylanisomycin was a prominent product in the first few days of fermentation, suggesting that acetylation of the C-3 hydroxyl group by acetyl Co-A is the final step in the biosynthesis of anisomycin. The source of the nitrogen within the ring and C-3 were undetermined. However, C-3 is not likely to be provided by the carboxylic acid group of tyrosine because tracking of radioactivity indicated that tyrosine undergoes decarboxylation during fermentation.

At the time, the Grumman F-14 Tomcat was the Navy's primary air superiority fighter and fleet defense interceptor. Then-Secretary of Defense Dick Cheney described the F-14 as 1960s technology, and drastically cut back F-14D procurement in 1989 before cancelling production altogether in 1991, in favor of the updated F/A-18E/F. The decision to replace the Tomcat with an all-Hornet Carrier Air Wing was controversial; Vietnam War ace and Congressman Duke Cunningham criticized the Super Hornet as an unproven design that compromised air superiority. In 1992, the Navy canceled the Navy Advanced Tactical Fighter (NATF), which would have been a navalized variant of the Air Force's Lockheed Martin F-22 Raptor. As a cheaper alternative to NATF, Grumman proposed substantial improvements to the F-14 beyond Quick Strike, but Congress rejected them as too costly and reaffirmed its commitment to the less expensive F/A-18E/F.

Within a few years of the publishing of the theory, its potential application to the field of conservation biology had been realised and was being vigorously debated in ecological circles. The idea that reserves and national parks formed islands inside human-altered landscapes (habitat fragmentation), and that these reserves could lose species as they 'relaxed towards equilibrium' (that is they would lose species as they achieved their new equilibrium number, known as ecosystem decay) caused a great deal of concern. This is particularly true when conserving larger species which tend to have larger ranges. A study by William Newmark, published in the journal Nature and reported in "The New York Times", showed a strong correlation between the size of a protected U.S. National Park and the number of species of mammals.

Growing computational power allows usage of thorough quantum-mechanical calculations at high theory levels and large basis sets for refining the molecular geometry of carbohydrates and subsequent prediction of NMR observables using GIAO and other methods with or without solvent effect account. Among combinations of theory level and a basis set reported as sufficient for NMR predictions were B3LYP/6-311G++(2d,2p) and PBE/PBE (see review). It was shown for saccharides that carbohydrate-optimized empirical schemes provide significantly better accuracy (0.0-0.5 ppm per C resonance) than quantum chemical methods (above 2.0 ppm per resonance) reported as best for NMR simulations, and work thousands times faster. However, these methods can predict only chemical shifts and perform poor for non-carbohydrate parts of molecules.

In one study, members of a bounded social network watched a battery of short audiovisual movies in an MRI scanner. Hypothesizing that similarity in neural responses tracks with social closeness, the researchers used the strength of neural synchrony measures across participants to reliably predict real-world social network proximity and friendship. Another example of how neural synchrony can be leveraged to predict outcomes involves the use of neural reference groups, which can predict behaviors like partisan stance on controversial topics at above-chance levels. This approach requires identifying groups of people that perceive and respond to the world in similar ways, measuring their brain activity and dispositional attitudes related to any stimuli of interest, and then using a synchrony-based classification method to predict whether new individuals see the world similarly or differently depending on their synchrony with the reference group. Together, these findings illustrate the power and potential for neural synchrony to contribute to brain-as-predictor models, ultimately framing neural synchrony as a tool for understanding real-world outcomes above and beyond behavioral measures alone.

The south-pointing chariot device was first invented by the Chinese mechanical engineer Ma Jun (c. 200–265 AD). It was a wheeled vehicle that incorporated an early use of differential gears to operate a fixed figurine that would constantly point south, hence enabling one to accurately measure their directional bearings. This effect was achieved not by magnetics (like in a compass), but through intricate mechanics, the same design that allows equal amounts of torque applied to wheels rotating at different speeds for the modern automobile. After the Three Kingdoms period, the device fell out of use temporarily. However, it was Zu Chongzhi who successfully re-invented it in 478, as described in the texts of the "Book of Song" and the "Book of Qi", with a passage from the latter below:

The function of huntingtin (Htt) is not well understood but it is involved in axonal transport. Huntingtin is essential for development, and its absence is lethal in mice. The protein has no sequence homology with other proteins and is highly expressed in neurons and testes in humans and rodents. Huntingtin upregulates the expression of brain-derived neurotrophic factor (BDNF) at the transcription level, but the mechanism by which huntingtin regulates gene expression has not been determined. From immunohistochemistry, electron microscopy, and subcellular fractionation studies of the molecule, it has been found that huntingtin is primarily associated with vesicles and microtubules. These appear to indicate a functional role in cytoskeletal anchoring or transport of mitochondria. The Htt protein is involved in vesicle trafficking as it interacts with HIP1, a clathrin-binding protein, to mediate endocytosis, the trafficking of materials into a cell. Huntingtin has also been shown to have a role in the establishment in epithelial polarity through its interaction with RAB11A.

"C. elegans" is unsegmented, vermiform, and bilaterally symmetrical. It has a cuticle (a tough outer covering, as an exoskeleton), four main epidermal cords, and a fluid-filled pseudocoelom (body cavity). It also has some of the same organ systems as larger animals. About one in a thousand individuals is male and the rest are hermaphrodites. The basic anatomy of "C. elegans" includes a mouth, pharynx, intestine, gonad, and collagenous cuticle. Like all nematodes, they have neither a circulatory nor a respiratory system. The four bands of muscles that run the length of the body are connected to a neural system that allows the muscles to move the animal's body only as dorsal bending or ventral bending, but not left or right, except for the head, where the four muscle quadrants are wired independently from one another. When a wave of dorsal/ventral muscle contractions proceeds from the back to the front of the animal, the animal is propelled backwards. When a wave of contractions is initiated at the front and proceeds posteriorly along the body, the animal is propelled forwards. Because of this dorsal/ventral bias in body bends, any normal living, moving individual tends to lie on either its left side or its right side when observed crossing a horizontal surface. A set of ridges on the lateral sides of the body cuticle, the alae, is believed to give the animal added traction during these bending motions.

The use of a virtual reality (VR) environment offers significant advantages in shipbuilding. The most important advantage is the possibility to review the model and to find out errors at early design stages, with an important cost reduction. VR allows an intuitive and quick evaluation of the model, queries, measurement of distances, ergonomic studies, collision detection, design changes evaluation, simulation of mounting, dismantling and operation tasks, etc. The viewer, called FVIEWER, which is part of the FORAN system, includes stereoscopic capability as feature, which means that it allows the 3D navigation around the model of a ship, being possible to use it with tracking devices. The module can be used during a 3D navigation with a great user-model interaction. The solution can be used in any kind of VR room as well as in portable solutions, workstations, etc.

Carroll writes that the book contains a "wealth of anecdotes", and that Susskind's "wit and storytelling abilities ... are pleasantly on display in" the book. George Johnson of "The New York Times" was critical of the beginning of the book, writing that the introduction on the basic concepts of relativity and quantum mechanics was excessive, especially for readers who have already read other popular science books on theoretical physics. "Time Magazine"'s Lev Grossman gave the book a B+, saying that "you could dismiss it all as nerd-on-nerd violence, but then you'd miss out on Susskind explaining why the universe is actually a hologram." Jesse Cohen of the "Los Angeles Times" criticized the book for its "tendency to meander" with personal anecdotes, although the book "glows with the warmth of conversation."

When high concentration is needed (500–1000 times), as occurs in the case of high efficiency multi-junction solar cells, it is likely that it will be crucial for commercial success at the system level to achieve such concentration with a sufficient acceptance angle. This allows tolerance in mass production of all components, relaxes the module assembling and system installation, and decreasing the cost of structural elements. Since the main goal of CPV is to make solar energy inexpensive, there are only a few surfaces that can be used. Decreasing the number of elements and achieving high acceptance angle, can be relaxed optical and mechanical requirements, such as accuracy of the optical surfaces profiles, the module assembling, the installation, the supporting structure, etc. To this end, improvements in sunshape modelling at the system design stage may lead to higher system efficiencies.

Her Russian spacecraft Soyuz TMA-05M docked with the ISS for a four-month stay at the orbiting outpost on July 17, 2012. The docking of the Soyuz spacecraft occurred at 4:51 GMT as the ISS flew over Kazakhstan at an altitude of 252 miles. The hatchway between the Soyuz spacecraft and the ISS was opened at 7:23 GMT and Williams floated into the ISS to begin her duties as a member of the Expedition 32 crew. On the Soyuz spacecraft, she was accompanied by Japan Aerospace Exploration Agency (JAXA) astronaut Akihiko Hoshide and Russian cosmonaut Yuri Malenchenko. Williams served as the commander of the ISS during her stay onboard ISS Expedition 33, succeeding Gennady Padalka. She became the commander of the International Space Station on September 17, 2012, being only the second woman to achieve the feat. Also in September 2012, she became the first person to do a triathlon in space, which coincided with the Nautica Malibu Triathlon held in Southern California. She used the International Space Station's own treadmill and stationary bike, and for the swimming portion of the race, she used the Advanced Resistive Exercise Device (ARED) to do weightlifting and resistance exercises that approximate swimming in microgravity. After swimming half a mile (0.8 km), biking 18 miles (29 km), and running 4 miles (6.4 km), Williams finished with a time of one hour, 48 minutes and 33 seconds, as she reported.

Timing of planting can play an important role in the severity of disease, with cassava planted in March showing a 74% incidence rate of CMV, compared with 4% in August. Seasonal distribution of the virus will vary with the climate. In tropical rain forest type climates, where it is wet and humid most of the year, rapid virus distribution occurred from November to June, and slow progress occurred from July to September. This timing correlated with higher and lower temperatures. In a study of the disease in the Ivory Coast of Africa, maximum rate of disease spread was reached two months after planting. Little to no infection occurs after three months, and variation in spread was due to change in temperature, radiation and population levels of whitefly.

As new technology companies require money and seed capital to grow and thrive, Israel's science and technology sector is backed by a strong venture capital industry. Between 2004 and 2013, the Israeli venture capital industry played a fundamental role in funding the development of Israel's high-tech sector. In 2013, Israeli companies had raised more venture capital as a share of GDP than companies in any other country as it attracted US$2 346 million alone during that year. Today, Israel is considered one of the biggest venture capital centers in the world outside the United States of America. Several factors have contributed to this growth. These include tax exemptions on Israeli venture capital, funds established in conjunction with large international banks and financial companies and the involvement of major organizations desirous to capitalize on the strengths of Israeli high-tech companies. These organizations include some of the world's largest multinational technology companies, including Apple, Cisco, Google, IBM, Intel, Microsoft, Oracle, Siemens and Samsung. In recent years, the share of venture capital invested in the growth stages of enterprises has flourished at the expense of early stage investments. Nowadays, Israeli companies are considered to be more popular than their American peers. For comparison, investments volume in Israeli startups grew by 140% during 2014-2018 and investments in technological startups from the U.S. grew by 64%.

Color vision, a feature of visual perception, is an ability to perceive differences between light composed of different wavelengths (i.e., different spectral power distributions) independently of light intensity. Color perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of photoreceptors by light entering the eye. Those photoreceptors then emit outputs that are propagated through many layers of neurons and then ultimately to the brain. Color vision is found in many animals and is mediated by similar underlying mechanisms with common types of biological molecules and a complex history of evolution in different animal taxa. In primates, color vision may have evolved under selective pressure for a variety of visual tasks including the foraging for nutritious young leaves, ripe fruit, and flowers, as well as detecting predator camouflage and emotional states in other primates.

Seeking answers, the Wrights constructed their own wind tunnel and equipped it with a sophisticated measuring device to calculate lift and drag of 200 different model-size wing designs they created. As a result, the Wrights corrected earlier mistakes in calculations of lift and drag and used this knowledge to construct their 1902 glider, third in the series. It became the first manned, heavier-than-air flying machine that was mechanically controllable in all three axes: pitch, roll and yaw. Its pioneering design also included wings with a higher aspect ratio than the previous gliders. The brothers successfully flew the 1902 glider hundreds of times, and it performed far better than their earlier two versions.

For costumes, flat storage may create more problems than it solves, since it is impossible to store them in this manner without forming folds and creases. Therefore, unless the costume is so weakened that it cannot support its own weight, hanging storage is perhaps the best option. Costumes which are unusually heavy (heavily beaded gowns, for instance), or those whose fabric may distort easily (such as some stretch fabrics, or those cut on the bias) should also be stored in flat storage. Garments suitable for hanging should be placed on plastic hangers which have been padded to mimic the shape of human shoulders, and covered with a plastic or cloth cover with an open bottom to allow air circulation while keeping the costume clean. Wooden hangers may have a high acid content, which may cause discolouration or decay to the costume. Likewise, metal hangers do not provide sufficient support, and may lead to distortion of the garments' shoulders. Therefore, both forms of hanging should be avoided.

Reactivated at Eglin Air Force Base, Florida in 1970 and equipped with McDonnell F-4 Phantom IIs. Supported the Tactical Air Warfare Center in weapon systems evaluation program tests from January–December 1973, and periodically thereafter until July 1978. Aircrews ferried F-4Es to Israel in October 1973. The 59th augmented intercept defense forces of North American Air Defense Command (NORAD) beginning 1 January 1976 – 15 January 1979 and 4 January 1982 – 5 April 1982. In 1979, "The Golden Pride" traded in their last F-4s for the McDonnell Douglas F-15 Eagle. Later, they provided personnel and equipment to fly combat air patrols and air intercept missions for contingency operations in Grenada from October–November 1983, and Panama December 1989 – January 1990. (I won't change the written information, but the 59th Tactical Fighter Squadron supported NORAD operations and pulled alert at Eglin (I was first in the 58th TFS and then for about 6 months in the 59th TFS.) I left the 59th TFS in February 1979.

Molecular mimicry occurs when epitopes are shared between host antigens and "Streptococcus" antigens. This causes an autoimmune reaction against native tissues in the heart that are incorrectly recognized as "foreign" due to the cross-reactivity of antibodies generated as a result of epitope sharing. The valvular endothelium is a prominent site of lymphocyte-induced damage. CD4+ T cells are the major effectors of heart tissue autoimmune reactions in RHD. Normally, T cell activation is triggered by the presentation of bacterial antigens. In RHD, molecular mimicry results in incorrect T cell activation, and these T lymphocytes can go on to activate B cells, which will begin to produce self-antigen-specific antibodies. This leads to an immune response attack mounted against tissues in the heart that have been misidentified as pathogens. Rheumatic valves display increased expression of VCAM-1, a protein that mediates the adhesion of lymphocytes. Self-antigen-specific antibodies generated via molecular mimicry between human proteins and streptococcal antigens up-regulate VCAM-1 after binding to the valvular endothelium. This leads to the inflammation and valve scarring observed in rheumatic valvulitis, mainly due to CD4+ T cell infiltration.

Earlier versions of the games had included Nostrums as gameplay elements, but these were replaced by equipable gear. Nostrums would have made permanent changes to the character and cannot be removed once used. They would have been available in two types, stable and unstable varieties, the latter referred to as "potlucks". Stable nostrums would have been expensive, but the player would know exactly what effect applying the nostrum would gain them. Unstable nostrums would be cheaper or found lying around the environment, but upon use, would require the player to select one of four random effects to alter their character, an idea inspired by "Heroes of Might and Magic" according to Levine. The Nostrum system was scrapped in favor of using gear as they found that the system was too similar to other ones that the player would have available in equipping their character, compared to the gear option. Similarly, earlier demonstrations of the game did not use Salt to power vigors, but instead each vigor would have a limited number of uses before it was exhausted. While more can be found around the game's environment, the player would have only been able to carry a limited number of vigors into battle, with more powerful vigors containing fewer charges.

Early Christian theologian Origen also presented suffering as necessary for the development of human beings. Theologian Mark Scott has argued that John Hick's theodicy is more closely aligned with Origen's beliefs than Irenaeus' and ought to be called an "Origenian theodicy". Origen used two metaphors for the world: it is a school and a hospital for souls, with God as Teacher and Physician, in which suffering plays both an educative and healing role. Through an allegorical reading of Exodus and the books of Solomon, Origen casts human development as a progression though a series of stages which take place in this life and after death. Origen believed that all humans will eventually reach heaven as the logical conclusion of God being 'all in all'. Hell is a metaphor for the purification of our souls: our sinful nature goes to 'Hell' and our original nature, created by God, goes to heaven. Scott argues that significant aspects of Origen's theology mean that there is a stronger continuation between it and Hick's theodicy. These aspects are Origen's allegorical treatment of Adam and Eve, the presentation of the world as a hospital or schoolroom, the progression he advocates of the human soul, and his universalism.
