In 2013 and 2014 DOE developed and proposed new test procedures for cooking products to allow direct comparison of energy transfer efficiency measurements among induction, electric resistance, and gas cooking tops and ranges. The procedures use a new hybrid test block made of aluminum and stainless steel, so it is suitable for tests on induction cookers. The proposed rule lists results of real lab tests conducted with the hybrid block. For comparable (large) cooking elements the following efficiencies were measured with ±0.5% repeatability: 70.7% - 73.6% for induction, 71.9% for electric coil, 43.9% for gas. Summarizing the results of several tests, DOE affirms that "induction units have an average efficiency of 72.2%, not significantly higher than the 69.9% efficiency of smooth—electric resistance units, or the 71.2% of electric coil units". Moreover, DOE reminds that the 84% induction efficiency, cited in previous Technical Support Documents, was not measured by DOE laboratories, but just "referenced from an external test study" performed in 1992.

Following her post-doctoral research with Pace, Ley moved to the Washington University School of Medicine to work with Jeffrey I. Gordon on the microbiome within the contexts of human obesity and mammalian evolution. She was then named an instructor in 2005 and research assistant professor two years later. She assisted on his groundbreaking paper to show that ones body weight is not solely dependent on how much one eats and how much energy one expends through exercise. They instead found a third factor, the microbial composition of one's intestines. After a dual career job search, they joined the faculty at Cornell University. In 2008, the family moved to Ithaca, New York.

According to Project Breakthrough, digital agriculture can help advance the United Nations Sustainable Development Goals by providing farmers with more real-time information about their farms, allowing them to make better decisions. Technology allows for improved crop production by understanding soil health. It allows farmers to use fewer pesticides on their crops. Soil and weather monitoring reduces water waste. Digital agriculture ideally leads to economic growth by allowing farmers to get the most production out of their land. The loss of agricultural jobs can be offset by new job opportunities in manufacturing and maintaining the necessary technology for the work. Digital agriculture also enables individual farmers to work in concert, collecting and sharing data using technology. and The hope is that young people want to become digital farmers

In France, Pascal Kintz and his colleagues were able to demonstrate the use of entomotoxicology to detect toxins that were not discovered during the analysis of body tissues and fluids of a body found roughly two months after death. A liquid chromatography analysis on organ tissue and Calliphoridae larvae found at the scene revealed the existence of five prescription medications. Triazolam, however, was only detected in the analysis of maggots and not in organ tissue samples. Comparative research showed increased sensitivity of toxicological analysis of Diptera samples over decomposed body tissues. A similar case involved the discovery of the remains of a 29-year-old known to abuse drugs, last seen alive five months prior. Through the use of GC and GC-MS techniques, Nolte and his partners discovered the presence of cocaine in decomposed muscle tissue and in maggots found on the body. However, due to the severity of decomposition of the muscle tissue, more suitable drug samples (devoid of decomposition byproducts) were reared from the maggots.

Ruthenium is the most active of the Fischer–Tropsch catalysts. It works at the lowest reaction temperatures, and it produces the highest molecular weight hydrocarbons. It acts as a catalyst as the pure metal, without any promoters, thus providing the simplest catalytic system of FT synthesis, where mechanistic conclusions should be the easiest—e.g., much easier than with iron as the catalyst. Like with nickel, the selectivity changes to mainly methane at elevated temperature. Its high price and limited world resources exclude industrial application. Systematic studies with ruthenium catalysts should contribute substantially to the further exploration of the fundamentals of FT synthesis. There is an interesting question to consider: what features have the metals nickel, iron, cobalt, and ruthenium in common to let them—and only them—be FT catalysts, converting the CO/H mixture to aliphatic (long chain) hydrocarbons in a ‘one step reaction’. The term ‘one step reaction’ means that reaction intermediates are not desorbed from the catalyst surface. In particular, it is amazing that the much carbided alkalized iron catalyst gives a similar reaction as the just metallic ruthenium catalyst.

Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instances of unrestricted submarine warfare and the introduction of submarine-launched ballistic missiles, which greatly increased the lethality of submarines.

The generative approach to second language (L2) acquisition (SLA) is a cognitive based theory of SLA that applies theoretical insights developed from within generative linguistics to investigate how second languages and dialects are acquired and lost by individuals learning naturalistically or with formal instruction in foreign, second language and lingua franca settings. Central to generative linguistics is the concept of Universal Grammar (UG), a part of an innate, biologically endowed language faculty which refers to knowledge alleged to be common to all human languages. UG includes both invariant principles as well as parameters that allow for variation which place limitations on the form and operations of grammar. Subsequently, research within the Generative Second-Language Acquisition (GenSLA) tradition describes and explains SLA by probing the interplay between Universal Grammar, knowledge of one's native language and input from the target language. Research is conducted in syntax, phonology, morphology, phonetics, semantics, and has some relevant applications to pragmatics.

A Swift script describes strongly typed data, application components, invocations of applications components, and the inter-relations in the dataflow between those invocations. The program statements will automatically run in parallel unless there is a data dependency between them, given sufficient computing resources. The design of the language guarantees that results of a computation are deterministic, even though the order in which statements executes may vary. A special file data type is built into Swift. It allows command-line programs to be integrated into a program as typed functions. This allows programmers to write programs that treat command-line programs and files in the same way as regular functions and variables. A concept of "mapping" is used to store and exchange complex data structures using a file system structure with files and directories.

Berners-Lee considered HTML an SGML application. The Internet Engineering Task Force (IETF) formally defined it as such with the mid-1993 publication of the first proposal for an HTML specification: "Hypertext Markup Language (HTML)" Internet-Draft by Berners-Lee and Dan Connolly, which included an SGML Document Type Definition to define the grammar. Many of the HTML text elements are found in the 1988 ISO technical report TR 9537 "Techniques for using SGML", which in turn covers the features of early text formatting languages such as that used by the RUNOFF command developed in the early 1960s for the CTSS (Compatible Time-Sharing System) operating system. These formatting commands were derived from those used by typesetters to manually format documents. Steven DeRose argues that HTML's use of descriptive markup (and the influence of SGML in particular) was a major factor in the success of the Web, because of the flexibility and extensibility that it enabled. HTML became the main markup language for creating web pages and other information that can be displayed in a web browser and is quite likely the most used markup language in the world today.

Five months prior to the collapse of the Soviet Union in December 1991, the United States and the Soviet Union completed the dismantling of their intermediate-range missiles on May 28 as outlined by the INF Treaty.  At the collapse of the Soviet Union, the United States focused on negotiations with Belarus, Kazakhstan, Russia, and Ukraine to preserve the START 1 treaty that further decreased nuclear armament.   The United States did not focus immediate attention on the preservation of the INF Treaty because the disarmament of INF missiles already occurred.  Eventually, the United States began negotiations to maintain the treaty in the six newly independent states of the former Soviet Union that contained INF sites subject to inspection: Belarus, Kazakhstan, Russia, Turkmenistan, Ukraine, and Uzbekistan. From these six countries, Belarus, Kazakhstan, Russia, and Ukraine entered agreements to continue the fulfillment of the INF Treaty.  The remaining two states, Turkmenistan and Uzbekistan, became passive participants in the negotiations with approval from the other participating states due to the presence of a single inspection site in each country. Inspection of INF missile sites continued until May 31, 2001, as stipulated by the 13-year inspection agreement within the treaty. After this period, the United States and Russia continued to share national technical means of verification and notifications to ensure that each state maintained compliance. The treaty states continued to meet at Special Verification Committees after the end of the inspection period.  There were 30 total meetings with the final meeting occurring in November 2016 in Geneva, Switzerland with the United States, Belarus, Kazakhstan, Russia, and Ukraine meeting to discuss compliance obligations.

Throughout his time in Berlin, Szilard worked on numerous technical inventions. In 1928 he submitted a patent application for the linear accelerator, not knowing of Gustav Ising's prior 1924 journal article and Rolf Widerøe's operational device, and in 1929 applied for one for the cyclotron. He was also the first person to conceive the idea of the electron microscope, and submitted the earliest patent for one in 1928. Between 1926 and 1930, he worked with Einstein to develop the Einstein refrigerator, notable because it had no moving parts. He did not build all of these devices, or publish these ideas in scientific journals, and so credit for them often went to others. As a result, Szilard never received the Nobel Prize, but Ernest Lawrence was awarded it for the cyclotron in 1939, and Ernst Ruska for the electron microscope in 1986.

Dr. Jack Herbert Rubinstein, an American pediatrician reported assessing a three-year-old girl with unusual facial and digital findings in 1958. Similarly, that same year Rubinstein had evaluated another child with similar characteristics, this time a seven-year-old boy. Having sensed a striking similarity between these two unrelated cases Rubinstein tried distributing photos and information concerning these two cases to other clinics in the U.S. from 1959 to 1960. Rubinstein graduated from Harvard Medical School and worked as the director of the Hamilton County Diagnostic Clinic for the Mentally Retarded. He has worked in behavioral and developmental pediatrics for many years prior to the discovery of this new syndrome.

The left axis of the figure is for plots of magnetic sail force versus characteristic length formula_34. The solid black line plots the MHD model force formula_163 from equation . The green line shows the value of ion gyroradius formula_85 72 km from equation . The dashed blue line plots the hybrid MHD/kinematic model from equation from Fujita04. The red dashed line plots a curve fit to simulation results from Ashida14. Although a good fit for these parameters, the curve fit range of this model does not cover some relevant examples. Additional simulation results from Hajiwara15 are shown for the MHD and kinematic model as single data points as indicated in the legend. These models are all in close agreement. The kinematic models predict less force than predicted by the MHD model. In other words, the fraction formula_165 of thrust force predicted by the MHD model is lost when formula_89 as plotted on the right axis. The solid blue and red lines show formula_165 for Fujita04 and Ashida18 respectively, indicating that operation with formula_34 less than 10% of formula_169 will have significant loss. Other factors in a specific magnetic sail design may offset this loss for values of formula_170.

It had a pioneering role in the development of magnetic resonance imaging, providing the first superconducting magnets for this application. The first commercial MRI whole body scanner was manufactured at its Osney Mead factory in Oxford in 1980 for installation at Hammersmith Hospital, London. Further innovations included the development of active shielding, whereby fringe fields hazardous to pacemaker wearers, causing difficulty and expense in siting, were virtually eliminated. Oxford Instruments was not able to capitalise on these inventions itself, granting royalty-free license to Philips and General Electric whilst developing a joint venture with Siemens in 1989: this was dissolved in 2004.

In late February 1946, George F. Kennan's "Long Telegram" from Moscow to Washington helped to articulate the US government's increasingly hard line against the Soviets, which would become the basis for US strategy toward the Soviet Union for the duration of the Cold War. The telegram galvanized a policy debate that would eventually shape the Truman administration's Soviet policy. Washington's opposition to the Soviets accumulated after broken promises by Stalin and Molotov concerning Europe and Iran. Following the WWII Anglo-Soviet invasion of Iran, the country was occupied by the Red Army in the far north and the British in the south. Iran was used by the United States and British to supply the Soviet Union, and the Allies agreed to withdraw from Iran within six months after the cessation of hostilities. However, when this deadline came, the Soviets remained in Iran under the guise of the Azerbaijan People's Government and Kurdish Republic of Mahabad. Shortly thereafter, on 5 March, former British prime minister Winston Churchill delivered his famous "Iron Curtain" speech in Fulton, Missouri. The speech called for an Anglo-American alliance against the Soviets, whom he accused of establishing an "iron curtain" dividing Europe from "Stettin in the Baltic to Trieste in the Adriatic".

The occurrence of HABs in some locations appears to be entirely natural (algal blooms are a seasonal occurrence resulting from coastal upwelling, a natural result of the movement of certain ocean currents) while in others they appear to be a result of increased nutrient pollution from human activities. The growth of marine phytoplankton is generally limited by the availability of nitrates and phosphates, which can be abundant in agricultural run-off as well as coastal upwelling zones. Other factors such as iron-rich dust influx from large desert areas such as the Sahara Desert are thought to play a major role in causing HAB events. Some algal blooms on the Pacific Coast have also been linked to occurrences of large-scale climatic oscillations such as El Niño events.

The next step is placement of the 'portals', or the small holes made to pass instruments into the joint. This is achieved by again passing a fresh hollow needle into the joint under x-ray control, usually in a slightly different position. The reason for this is so the surgeon can ensure that the needle, and subsequent cannulae do not penetrate and damage the acetabular labrum or cartilage joint surfaces (see fig. 5). Again, surgeons will have their own preferences as to their preferred placement. Through this hollow needle, a long thin flexible guide wire is passed into the joint, and the needle is removed over it, leaving the guide wire in situ. A small cut in the skin is made around the wire, to allow for larger cannulae to be placed over the wire through the portal. The wire therefore guides the larger cannulae into the joint. The most common external diameters of cannulae used are between 4.5 and 5.5 mm. Once the surgeon is satisfied that the cannula is in the correct position, by a combination of feel and x-ray guidance, the guide wire can be withdrawn. Once the first portal is correctly placed, any further portals may be created once the camera is in position, to ensure that they are placed with minimal risk to the joint surfaces. This process can be repeated to gain as many points of entry to the hip joint as the surgeon requires, normally between two and four. Certain of these entry points will be used for the viewing arthroscope and others for operating instruments.

At least five explorations took place in the Strathy Township property before 1995. In 1934 Strathy Basin and Erie Canadian Mines conducted prospected sections of the 1995 claim block. A wide rusted zone within a dike was announced as containing values of $7.50 combined gold, copper and nickel. Little work has been completed in this area. In 1959 and 1960, Goldfields Mining conducted a basic airborne electromagnetic survey and magnetic survey over the property. Several holes were drilled and intersected mostly mafic to intermediate volcanic rocks and areas of stringer sulfides with pyrrhotite, pyrite and some chalcopyrite. No assays were reported. In 1970 E. L. McVeigh occupied a section of the property, including the area that was once owned by Strathy Basin Mines. McVeigh conducted geophysical surveys over Strathy Basin's mineralized zone and announced no conductors. From 1974 to 1975 Vale Limited owned an extensive section of the Strathy Township property. They conducted magnetic and electromagnetic surveys, as well as mapping and drilling. Vale announced that they intersected mineralized sulfide zones ranging from to thick.

The race started at 15:00 local time () on 31 July 2022, and lasted for 70 laps. George Russell kept first place into turn one, from Carlos Sainz Jr. and Charles Leclerc. Further back, Esteban Ocon defended from his Alpine teammate, Fernando Alonso, who later complained about Ocon's defence on the team radio. Contact between Lance Stroll and Alexander Albon meant the latter had to pit to replace a damaged front wing. Kevin Magnussen was forced to pit after he was shown the black and orange flag, due to damage to the right side of his front wing. The virtual safety car (VSC) was called out to pick up debris caused by the collisions. Once the VSC ended, Russell immediately pulled a 2.5 second gap to Sainz. With the help of DRS, Max Verstappen made his way through the grid, overtaking his teammate, both Alpine cars and Lando Norris, before pitting and undercutting Lewis Hamilton. Russell and Sainz both had slow pit stops, which allowed Leclerc to overcut Sainz and close up to Russell, later overtaking him into turn one. Verstappen then closed the gap to Russell and Sainz, as Leclerc extended his lead at the front.

Findley wrote in a personal capacity and his opinions were not endorsed by any U.S. political party, but they did present an alternative to then-U.S. President Jimmy Carter's approach to nuclear proliferation in Latin America. Findley's Washington Post article argued that "a bilateral, on-site, nuclear verification agreement between Argentina and Brazil could help to arrest mounting suspicion over the ultimate nuclear aspirations of these two important states." The congressman first advocated for the common rejection of PNEs, followed by the "continuing, mutual, on-site monitoring of their respective nuclear facilities." Findley did not consider a bilateral arrangement as a substitute for the IAEA verification regime, but as an "additional element of assurance and protection between two states whose past relations have at time been quite troubled."

Apprentice electricians work 32 to 40+ hours per week at the trade under the supervision of a journeyman wireman and receive pay and benefits. They spend an additional 8 hours every other week in classroom training. At the conclusion of training (five years for inside wireman and outside lineman, less for telecommunications), apprentices reach the level of journeyman wireman. All of this is offered at no charge, except for the cost of books (which is approximately $200–600 per year), depending on grades. Persons completing this program are considered highly skilled by employers and command high pay and benefits. Other unions such as the United Brotherhood of Carpenters and Joiners of America, United Association of Plumbers, Fitters, Welders and HVAC Service Techs, Operating Engineers, Ironworkers, Sheet Metal Workers, Plasterers, Bricklayers and others offer similar programs.

Human eyes are somewhat distinctive in the animal kingdom in that the sclera is very plainly visible whenever the eye is open. This is not just due to the white color of the human sclera, which many other species share, but also to the fact that the human iris is relatively small and comprises a significantly smaller portion of the exposed eye surface compared to other animals. It is theorized that this adaptation evolved because of our social nature as the eye became a useful communication tool in addition to a sensory organ. It is believed that the conspicuous sclera of the human eye makes it easier for one individual to identify where another individual is looking, increasing the efficacy of this particular form of nonverbal communication, called cooperative eye hypothesis. Animal researchers have also found that, in the course of their domestication, dogs have also developed the ability to pick up visual cues from the eyes of humans. Dogs do not seem to use this form of communication with one another and only look for visual information from the eyes of humans.

As an example, consider that for children in the sensorimotor stage, teachers should try to provide a rich and stimulating environment with ample objects to play with. Then with children in the concrete operational stage, learning activities should involve problems of classification, ordering, location, conservation using concrete objects. The main focus is on the younger years of development. "Assimilation" occurs when the perception of a new event or object occurs to the learner in an existing schema and is usually used in the context of self-motivation. In "Accommodation", one accommodates the experiences according to the outcome of the tasks. The highest form of development is "equilibration". Equilibration encompasses both assimilation and accommodation as the learner changes how they think to get a better answer.

The BBC's own website regarded "Quatermass II" unfavourably when reviewing its DVD release in 2005. "The script is too often let down by the production's rougher edges. Your heart will break halfway through episode six as it all falls apart. And then there's Monica Gray [sic] – less an actress than a finishing school on legs." Writing in "The Times" in 2006, Morgan Falconer claimed to find racist undertones in the serial. "Quatermass, for instance, often seemed to have an unhealthy preoccupation with blackness, a barely veiled commentary on racial change in Britain. In one scene in "Quatermass II", the Professor stands outside a pub and watches the sky fill with dark asteroids. 'They’re coming in their thousands,' he says, 'this is it.'" However, this interpretation of the serial is not widespread, and is undermined in episode five where an Irish immigrant helps Quatermass sabotage the aliens' food supply system. In any case, it is in direct contrast with Kneale's deliberate attack on racial intolerance in "Quatermass and the Pit".

Alfisols are a soil order in USDA soil taxonomy. Alfisols form in semi-arid to humid areas, typically under a hardwood forest cover. They have a clay-enriched subsoil and relatively high native fertility. "Alf" refers to aluminium (Al) and iron (Fe). Because of their productivity and abundance, Alfisols represent one of the more important soil orders for food and fiber production. They are widely used both in agriculture and forestry, and are generally easier to keep fertile than other humid-climate soils, though those in Australia and Africa are still very deficient in nitrogen and available phosphorus. Those in monsoonal tropical regions, however, have a tendency to acidify when heavily cultivated, especially when nitrogenous fertilizers are used.

The Chinese government adopted an "informatization" approach in the 1990s, promoting IT development in all major industries, including the health sector, with one goal being to bridge the information divide. HIT policy began in 1995 with the "Golden Health Project," which sought to create the foundation for electronically linking health administration departments and hospitals as well as medical education and research institutes. Government efforts in the 21st century increasingly focus on health IT. For example, the 2003–2010 Ministry of Health Guidelines for HIT Development in China call for the introduction of EHRs and regional health information networks to be implemented throughout the country. Many hospitals are considering system-wide upgrades, and larger budgets are more readily available for these kinds of investments.

Shortly after the invention of the telephone, attempts were made to adapt the technology for military use. Telephones were already being used to support military campaigns in British India and in British colonies in Africa in the late 1870s and early 1880s. In the United States telephone lines connected fortresses with each other and with army headquarters. They were also used for fire control at fixed coastal defence installations. The first telephone for use in the field was developed in the United States in 1889 but it was too expensive for mass production. Subsequent developments in several countries made the field telephone more practicable. The wire material was changed from iron to copper, devices for laying wire in the field were developed and systems with both battery-operated sets for command posts and hand generator sets for use in the field were developed. The first purposely-designed field telephones were used by the British in the Second Boer War. They were used more extensively in the Russo-Japanese War, where all infantry regiments and artillery divisions on both sides were equipped with telephone sets. By the First World War the use of field telephones was widespread, and a start was made at intercepting them.

Bio-layer interferometry (BLI) is a label-free technology for measuring biomolecular interactions (protein:protein or protein:small molecule). It is an optical analytical technique that analyzes the interference pattern of white light reflected from two surfaces: a layer of immobilized protein on the biosensor tip, and an internal reference layer. Any change in the number of molecules bound to the biosensor tip causes a shift in the interference pattern that can be measured in real-time, providing detailed information regarding the kinetics of association and dissociation of the two molecule molecules as well as the affinity constant for the protein interaction (k, k and K). Due to sensor configuration, the technique is highly amenable to both purified and crude samples as well as high throughput screening experiments. The detection method can also be used to determine the molar concentration of analytes.

The numeracy of indigenous peoples is studied to identify universal aspects of numerical cognition in humans. Notable examples include the Pirahã people who have no words for specific numbers and the Munduruku people who only have number words up to five. Pirahã adults are unable to mark an exact number of tallies for a pile of nuts containing fewer than ten items. Anthropologist Napoleon Chagnon spent several decades studying the Yanomami in the field. He concluded that they have no need for counting in their everyday lives. Their hunters keep track of individual arrows with the same mental faculties that they use to recognize their family members. There are no known hunter-gatherer cultures that have a counting system in their language. The mental and lingual capabilities for numeracy are tied to the development of agriculture and with it large numbers of indistinguishable items.

During the 1970s, she rejected the belief among many contemporary designers that computers and digitalization would compromise the International Typographic Style; instead, she exploited pixelation and other digitization "errors" as integral parts of digital art, a position she has held throughout her career.

On 23 March 1948, Prime Minister Jawaharlal Nehru introduced the Atomic Energy Bill in the Indian Parliament, and it was subsequently passed as the Indian Atomic Energy Act. Modelled on the British Atomic Energy Act 1946, the Act granted sweeping powers to the central government over nuclear science and research, including surveying for atomic minerals, the development of such mineral resources on an industrial scale, conducting research regarding the scientific and technical problems connected with developing atomic energy for peaceful purposes, the training and education of the necessary personnel and the fostering of fundamental research in the nuclear sciences in Indian laboratories, institutes and universities. Around the same time, the Government of West Bengal sanctioned the construction of a nuclear physics institute under the University of Calcutta; the cornerstone was laid in May 1948, and the institute was inaugurated on 11 January 1950 by Irène Joliot-Curie.

The first use of the term "citizen science" can be found in a January 1989 issue of "MIT Technology Review", which featured three community-based labs studying environmental issues. In the 21st century, the number of citizen science projects, publications, and funding opportunities has increased. Citizen science has been used more over time, a trend helped by technological advancements. Digital citizen science platforms, such as Zooniverse, store large amounts of data for many projects and are a place where volunteers can learn how to contribute to projects. For some projects, participants are instructed to collect and enter data, such as what species they observed, into large digital global databases. For other projects, participants help classify data on digital platforms. Citizen science data is also being used to develop machine learning algorithms. An example is using volunteer-classified images to train machine learning algorithms to identify species. While global participation and global databases are found on online platforms, not all locations always have the same amount of data from contributors. Concerns over potential data quality issues, such as measurement errors and biases, in citizen science projects are recognized in the scientific community and there are statistical solutions and best practices available which can help.

The most well studied of these is "Bdellovibrio bacteriovorus", which is found almost exclusively in host dependent growth in nature. In this free swimming attack form after searching for prey using its pili, it burrows through the host outer membrane/ peptidoglycan cell wall and enters the periplasmic space. The "Bdellovibrio" bacterium then forms a structure called a bdelloplast. This bdelloplast is created as the host cell is modified to become spherical in shape. Inside the bdelloplast, the singular large flagellum of the predatory Bdellovibrio is lost. The host cell is then rapidly killed allowing the passage of molecules from the interior of the host cytoplasm through to the periplasm freely, and the periplasm dwelling "Bdellovibrio" to feed. Using some of these molecules the "Bdellovibrio" creates a protective environment by reinforcing the peptidoglycan cell wall of the host in which it now dwells using amidases and transpeptidases. After around 4hrs, depending on ambient temperature, the "Bdellovibrio" has increased in size dramatically through this nourishment. It divides to replicate and then leaves via a final lysis of the host's cell wall and membranes. The newly emerging "Bdellovibrio" use their newly grown powerful flagella to swim away and find the next suitable host. Because of this intermittent bdelloplast stage, and momentary parasitic phase (15-20 mins), "Bdellovibrio" could be considered bacterial predators or parasites.

The Wind Science and Engineering (WiSE) Research Center was established in 1970 as the Institute for Disaster Research, following the F5 Lubbock tornado that caused 26 fatalities and over $100 million in damage. Following the aftermath of the tornado, the WISE center developed the first comprehensive wind engineering report of its kind. In 2006, the Enhanced Fujita scale was developed at TTU to update the original Fujita scale that was first introduced in 1971. In 2003, with support from the National Science Foundation, the first interdisciplinary Ph.D. program dedicated to wind science and engineering was developed. Later, the Texas Wind Energy Institute (TWEI) was established as a partnership between TTU and Texas State Technical College designed to develop education and career pathways to meet workforce and educational needs of the expanding wind energy industry. A Bachelor's degree program in Wind Energy was opened in Spring 2012 and now has more than 100 students in the process of completing the degree requirements.

Accelerator mass spectrometry (AMS) is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis. The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass ("abundance sensitivity", e.g. C from C). The method suppresses molecular isobars completely and in many cases can separate atomic isobars (e.g. N from C) also. This makes possible the detection of naturally occurring, long-lived radio-isotopes such as Be, Cl, Al and C. Their typical isotopic abundance ranges from 10 to 10. AMS can outperform the competing technique of decay counting for all isotopes where the half-life is long enough. Other advantages of AMS include its short measuring time as well as its ability to detect atoms in extremely small samples.

Triiodide is a model system in photochemistry. Its reaction mechanism has been studied in gas phase, solution and the solid state. In gas phase, the reaction proceeds in multiple pathways that include iodine molecule, metastable ions and iodine radicals as photoproducts, which are formed by two-body and three-body dissociation. In condensed phases, due to confinement, geminate recombination is more common. In solution, only two-body dissociation of triiodide has been observed. In the protic solvents, an iodine atom at the shorter end of the triiodide anion dissociates upon photoexcitation showing two-body dissociation. In the solid state, the triiodide photochemistry has been studied in compounds involving quaternary ammonium cations, such as tetrabutylammonium triiodide. It has been shown that the solid state photoreaction mechanism depends on the light wavelength, yielding fast recovery in a few picoseconds or going through a two-stage process that involves the formation and break-up of a tetraiodide intermediate on longer timescales. Besides, triiodide photochemistry is an important contributor in the environmental cycle of iodine. Because of the presence of heavy iodine atoms and the well-calibrated chemical pathways, triiodide has also become a computational benchmark system for relativistic quantum chemistry.

While Carscadden was principal, GCI grew in enrollment and required additional teaching space. Renovations on the building were conducted between 1905 and when the school re-opened in September 1906. The corners of the original cross structure were filled and a third storey added, which made up most of the midsection of the present building. In addition, a school cadet corps was organized in 1899, which overtime became a significant part of the school's activities until the 1970s, and which eventually became the present-day 21 Royal Highland Fusiliers of Canada Army Cadets. After thirty years as principal, Carscadden retired in the summer of 1914, but remained to teach English for another ten years. He was recognized for his excellence in teaching and as a school administrator by receiving an honorary LLD from the University of Toronto in 1925.

FBS is somewhat controversial because it comes from the blood of a dairy cow fetus. The two issues with this is that it is a) reliant on animals, hence defeating the goal of cellular agriculture and b) expensive because it is so inaccessible. Additionally, from a scientific perspective, FBS is chemically undefined, meaning that its composition varies between animals. For the sake of research consistency, this is not desirable. The ideal culture medium is one that is simple, can stimulate proliferation, is unreliant on animals, is accessible and is cheap. However, because mammalian cells rely on a complex array of growth factors, finding a culture medium that satisfies all five of these criteria is an ongoing challenge. Insect cells on the other hand, are biologically simpler organisms than mammals. They contain a fluid called hemolymph rather than blood, so they do not rely on all the same growth factors as mammalian cells. Instead, insect cell medium typically uses a basal medium (such as Eagle's Medium, Grace's Insect Medium or Schneider's Drosophila Medium), which is supplemented with plant based additives such as yeastolate, primatone RL, hydrolysates, pluronic lipids and peptides.

The mechanism of regeneration using an active collagen scaffold has been largely clarified. The scaffold retains regenerative activity provided that it has been prepared with appropriate levels of the specific surface (pore size in range 20-125 µm), degradation rate (degradation half-life 14 ± 7 days) and surface chemical features (ligand densities for integrins α1β1 and α2β1 must exceed approximately 200 μΜ α1β1 and α2β1 ligands). It has been hypothesized that specific binding of a sufficient number of contractile cells (myofibroblasts) on the scaffold surface, occurring within a narrow time window, is required for induction of skin regeneration in the presence of this scaffold. Studies with skin wounds have been extended to transected peripheral nerves, and the combined evidence supports a common regeneration mechanism for skin and peripheral nerves using this scaffold.

The receiver consisted of an Adcock array consisting of four tall wooden towers arranged at the corners of a square. Each tower had three sets (originally two) of receiver antennas, one at 45, 95 and 215 feet off the ground. The mean height of the transmitter stack was 215 feet, which is why the topmost antenna was positioned at the same altitude in order to produce a reception pattern that was identical to the transmission. A set of motor-driven mechanical switches allowed the operator to select which antenna was active. The output of the selected antenna on each of the four towers was sent to a single radiogoniometer system (not Watt's own huff-duff solution). By connecting the antennas together in X-Y pairs the horizontal bearing could be measured, while connecting together the upper and lower antennas allowed the same goniometer to be used to measure the vertical angle.

Michael DeBakey was born in Lake Charles, Louisiana on September 7, 1908. His parents, Shiker and Raheeja Dabaghi (the name was anglicized to DeBakey before Michael's birth) were immigrants from Marjeyoun, Lebanon (then Ottoman Syria) although they did not meet until both were living in the United States. Shiker, who had been a traveling salesman, settled in Lake Charles in the early 1900s and began to establish retail businesses, particularly general and drug stores. Both of them spoke French. Young Michael helped out with manual chores and keeping the books. DeBakey was the eldest of five children. His brother Ernest also became a physician, specializing in general and thoracic surgery. His sisters Lois and Selma were also scholarly, and eventually joined their eldest brother at Baylor College of Medicine as faculty members in medical communications. Another sister, Selena, died in 1952.

Archaeogenetics studies of the 2010s have been able to resolve the "migrationist vs. diffusionist" question to some extent. The study by Olalde et al. (2017) found only "limited genetic affinity" between individuals associated with the Beaker complex in Iberia and in Central Europe, suggesting that migration played a limited role in its early spread. However, the same study found that the further dissemination of the mature Beaker complex was very strongly linked to migration. This is true especially for Britain, where the spread of the Beaker culture introduced high levels of steppe-related ancestry, resulting in a near-complete transformation of the local gene pool within a few centuries, to the point of replacement of about 90% of the local Neolithic-derived lineages.

In 2012, Ng and Dean created a network that learned to recognize higher-level concepts, such as cats, only from watching unlabeled images. Unsupervised pre-training and increased computing power from GPUs and distributed computing allowed the use of larger networks, particularly in image and visual recognition problems, which became known as "deep learning".

LNS is characterized by three major hallmarks: neurologic dysfunction, cognitive and behavioral disturbances including self-mutilation, and uric acid overproduction (hyperuricemia). Damage to the basal ganglia causes affected individuals to adopt a characteristic fencing stance due to the nature of the lesion. Some may also have macrocytic anemia due to the faulty DNA synthesis, most likely due to deficient purine synthesis that leads to a lag of cell division with respect to increases in cell mass. Virtually all patients are male; males experience delayed growth and puberty, and most develop shrunken testicles or testicular atrophy. Female carriers are at an increased risk for gouty arthritis but are usually otherwise unaffected.

Bryce Bayer's patent (U.S. Patent No. 3,971,065) in 1976 called the green photosensors "luminance-sensitive elements" and the red and blue ones "chrominance-sensitive elements". He used twice as many green elements as red or blue to mimic the physiology of the human eye. The luminance perception of the human retina uses M and L cone cells combined, during daylight vision, which are most sensitive to green light. These elements are referred to as "sensor elements", "sensels", "pixel sensors", or simply "pixels"; sample values sensed by them, after interpolation, become image pixels. At the time Bayer registered his patent, he also proposed to use a cyan-magenta-yellow combination, that is another set of opposite colors. This arrangement was impractical at the time because the necessary dyes did not exist, but is used in some new digital cameras. The big advantage of the new CMY dyes is that they have an improved light absorption characteristic; that is, their quantum efficiency is higher.

The EAP has its roots within the earlier "Agile Combat Aircraft" (ACA), a collaborative initiative studying advanced technologies to produce more capable fighter aircraft. Upon the announcement of the EAP during October 1983, it was intended to be a multinational European effort; however, neither West Germany or Italy would ultimately contribute financially, thus the programme relied upon a combination of British public and British and European private funding instead. Having been manufactured in sections across multiple facilities, the sole EAP aircraft (serial "ZF534") was rolled out during April 1986. Performing its maiden flight on 8 August 1986, the EAP would fly over 250 sorties prior to its grounding on 1 May 1991, by which point the aircraft had fulfilled its intended purpose as a development aid.

Around 530 BC, when Pythagoras was about forty years old, he left Samos. His later admirers claimed that he left because he disagreed with the tyranny of Polycrates in Samos, Riedweg notes that this explanation closely aligns with Nicomachus's emphasis on Pythagoras's purported love of freedom, but that Pythagoras's enemies portrayed him as having a proclivity towards tyranny. Other accounts claim that Pythagoras left Samos because he was so overburdened with public duties in Samos, because of the high estimation in which he was held by his fellow-citizens. He arrived in the Greek colony of Croton (today's Crotone, in Calabria) in what was then Magna Graecia. All sources agree that Pythagoras was charismatic and quickly acquired great political influence in his new environment. He served as an advisor to the elites in Croton and gave them frequent advice. Later biographers tell fantastical stories of the effects of his eloquent speeches in leading the people of Croton to abandon their luxurious and corrupt way of life and devote themselves to the purer system which he came to introduce.

The Aharonov–Bohm phase shift due to the gravitational potential should also be possible to observe in theory, and in early 2022 an experiment was carried out to observe it based on an experimental design from 2012. In the experiment, ultra-cold rubidium atoms in superposition were launched vertically inside a vacuum tube and split with a laser so that one part would go higher than the other and then recombined back. Outside of the chamber at the top sits an axially symmetric mass that changes the gravitational potential. Thus, the part that goes higher should experience a greater change which manifests as an interference pattern when the wave packets recombine resulting in a measurable phase shift. Evidence of a match between the measurements and the predictions was found by the team. Multiple other tests have been proposed.

Developmental advising was first introduced by Crookson in 1972. This approach is focused on helping students explore and define academic, career and life goals and pathways, and develop problem-solving and decision-making skills through collaborative and process-oriented advising. Fostering a relationship between the advisor and student is critical to this model, which is based primarily on adult development theory and student development theory. Although many studies have shown that students generally prefer this approach it can require a greater commitment of time and resources compared to other advising models. It also allows for advisors to honor the life and career experiences of adult learners in higher education.

The sea dike top level at 8 m above the mean sea level and 50 m wide at the top surface, would be nearly 600 km long connecting Indian mainland to South east of Bangladesh forming transnational high way and rail route from the Indian subcontinent to East Asia up to Singapore and China. Also this dike can be used as access way connecting deep sea ports located close to this dike. The proposed dike would be similar to the land reclamation of North Sea area called Delta Works in Netherlands. The experience of the Saemangeum Seawall already constructed in South Korea which is 33 km long and with 36 metres average depth, can be utilised for this project which is a lesser challenging project.

Junior Colt Ryan tied the game with a free throw in regulation and then scored his team's final six points in overtime to lift host Evansville to an 80–77 overtime victory over Butler in the season-opener for both teams at the new Ford Center on Saturday, Nov. 12. Between Ryan's clutch points, the game took a bizarre twist. Butler led 69–68 with Evansville in possession and 0:15 remaining. The Aces' Ned Cox missed a jump shot with 0:07 remaining and there was a loose ball scramble for the rebound. Butler's Jackson Aldridge was whistled for a foul with 0:00.9 left, sending Ryan to the line. The Evansville scoring leader missed the first free throw, but made the second to tie the game. Butler's Emerson Kampen then threw a full-court pass to center Andrew Smith, who caught the ball and laid it in at the buzzer for an apparent game-winning shot. The game officials huddled, and claimed a foul was called before the shot, sending Smith to the free throw line with 0:00.2 left. Smith missed both shots, forcing the overtime period.

The Dulong–Petit limit results from the equipartition theorem, and as such is only valid in the classical limit of a microstate continuum, which is a high temperature limit. For light and non-metallic elements, as well as most of the common molecular solids based on carbon compounds at standard ambient temperature, quantum effects may also play an important role, as they do in multi-atomic gases. These effects usually combine to give heat capacities lower than 3"R" per mole of "atoms" in the solid, although in molecular solids, heat capacities calculated "per mole of molecules" in molecular solids may be more than 3"R". For example, the heat capacity of water ice at the melting point is about 4.6"R" per mole of molecules, but only 1.5"R" per mole of atoms. The lower than 3"R" number "per atom" (as is the case with diamond and beryllium) results from the “freezing out” of possible vibration modes for light atoms at suitably low temperatures, just as in many low-mass-atom gases at room temperatures. Because of high crystal binding energies, these effects are seen in solids more often than liquids: for example the heat capacity of liquid water is twice that of ice at near the same temperature, and is again close to the 3"R" per mole of atoms of the Dulong–Petit theoretical maximum.

Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application. This requires adequate tooling and adapters for replenishment in multiple countries. For example for overlanders and users of autogas traveling with a container originating in one country to other parts of the world this is a major concern. This article describes existing standards and the standards in use for a number of countries. For disposable containers the availability per country is described. Filling stations may be able and allowed to fill foreign containers if adequate adapters are available. Adapters are provided by, amongst others, camping stores.

The Lithic Period was followed by what archaeologists have called the Pre-Ceramic Period, or alternatively the Late Archaic Period, and is characterised by increasing societal complexity, rising population levels and the construction of monumental ceremonial centres across the Andean region. It is the latter of these features that remains the most visually obvious characteristic of the Pre-Ceramic amongst archaeologists, and indicates that by this time, Andean society was sufficiently developed that it could organise large building projects involving the management of labor. The Pre-Ceramic Period also saw a rise in the population of the Andean region, with the possibility that many people were partially migratory, spending much of their year in rural areas but moving to the monumental ceremonial centers for certain times which were seen as having special significance. The Pre-Ceramic also saw changes in the climate of the Andean region, for the culmination of the Ice Age had led to an end of the glacial meltback which had been occurring throughout the Lithic Period, and as a result the sea levels on the west coast of South America stabilized.

Deep sea whale falls are thought to be hotspots of adaptive radiation for specialized fauna. Organisms that have been observed at deep-sea whale fall sites include octopus, giant isopods, squat lobsters, polychaetes, prawns, shrimp, lobsters, hagfish, "Osedax", crabs, sea cucumbers, and sleeper sharks. New species have been discovered, including some potentially specializing in whale falls. It has been postulated that whale falls generate biodiversity by providing evolutionary stepping stones for multiple lineages to move and adapt to new environmentally-challenging habitats. Researchers estimate that 690,000 carcasses/skeletons of the nine largest whale species are in one of the four stages of succession at any one time. This estimate implies an average spacing of and as little as along migration routes. They hypothesize that this distance is short enough to allow larvae to disperse/migrate from one to another.

Some researchers claim the IOM was too definitive in its recommendations and made a mathematical mistake when calculating the blood level of vitamin D associated with bone health. Members of the IOM panel maintain that they used a "standard procedure for dietary recommendations" and that the report is solidly based on the data. Research on vitamin D supplements, including large-scale clinical trials, is continuing.

She continued in the traditional role of a daughter in a well-connected family, attending social events and maintaining a sweet and polite manner, which led to her nickname as "the Rose of Jedburgh" among Edinburgh socialites. Meanwhile, a young tutor came to stay with the family in Burntisland to educate her younger brother Henry. The tutor, Mr. Craw, was a Greek and Latin scholar, and Somerville asked him to purchase elementary books on algebra and geometry for her. He presented Somerville with Euclid's "Elements" and "Algebra" by John Bonnycastle. Somerville would rise early to play the piano, painted during the day, and stayed up late to study Euclid and algebra. When Lord Balmuto, a family friend, invited her to visit his family Somerville saw her first laboratory. She also spent some time with the Oswalds family in Dunnikeir, whose daughter, a bold horsewoman who impressed Somerville, became a Greek and Latin scholar and married Thomas Bruce, 7th Earl of Elgin.

Although cost estimates of unbuilt projects are always dubious, and the specifications are not identical (conventional telescopes have lower noise temperature, but the ATA has a larger field of view, for example), the ATA has potential promise as a much cheaper radio telescope technology for a given effective aperture. For example, the amount spent on the first ATA-42 phase, including technology development, is roughly one third of the cost of a new copy of a Deep Space Network 34 m antenna of similar collecting area. Similarly, the estimated total cost of building the remaining 308 dishes was estimated () at about $41 million. This is about two times cheaper than the $85 million cost of the last large radio astronomy antenna built in the US, the Green Bank Telescope, of similar collecting area. The contractor filed for a $29 million overrun, but only $4 million of this was allowed.

There are two types of social solidarity. The first is mechanical solidarity, where people are held together because they all serve the same purpose, or do the same things (as in a hunter-gatherer society), and their collective consciousness is therefore very strong. The people are all self-reliant, but they share the same experiences, understandings, and core beliefs, and can relate in that way. The second type of solidarity, organic solidarity, is the result of a substantial division of labor that has occurred due to much growth of dynamic density. People in organic solidarity have more specialized skills, so individuals are no longer self-sustaining. An example of this is that a philosopher has neither the time nor the ability to grow his own food, and so he is dependent upon a farmer and various other individuals so he can eat. In this situation, solidarity in society comes from the fact that people need the contribution of an increasing number of other people in order to function, and even to survive. (Ritzer, 2007)

There is also a paradigm shift in the drug discovery community to shift away from HTS, which is expensive and may only cover limited chemical space, to the screening of smaller libraries (maximum a few thousand compounds). These include fragment-based lead discovery (FBDD) and protein-directed dynamic combinatorial chemistry. The ligands in these approaches are usually much smaller, and they bind to the target protein with weaker binding affinity than hits that are identified from HTS. Further modifications through organic synthesis into lead compounds are often required. Such modifications are often guided by protein X-ray crystallography of the protein-fragment complex. The advantages of these approaches are that they allow more efficient screening and the compound library, although small, typically covers a large chemical space when compared to HTS.

Recently new materials have been developed that could be superior to RCC. The prototype SHARP (Slender Hypervelocity Aerothermodynamic Research Probe) is based on ultra-high-temperature ceramics such as zirconium diboride (ZrB) and hafnium diboride (HfB). The thermal protection system based on these materials would allow to reach a speed of Mach number 7 at sea level, Mach 11 at 35000 meters and significant improvements for vehicles designed for hypersonic speed. The materials used have thermal protection characteristics in a temperature range from 0 °C to + 2000 °C, with melting point at over 3500 °C. They are also structurally more resistant than RCC, so they do not require additional reinforcements, and are very efficient in re-irradiating the absorbed heat. NASA funded (and subsequently discontinued) a research and development program in 2001 for testing this protection system through the University of Montana.

Once nitrendipine is ingested, it is absorbed by the gut and metabolized by the liver before it goes into the systemic circulation and reaches the cells of the smooth muscles and cardiac muscle cells. It binds more effectively with L-type calcium channels in smooth muscle cells because of its lower resting membrane potential. The nitrendipine diffuses into the membrane and binds to its high affinity binding site on the inactivated -type calcium channel that's located in between each of the 4 intermembrane components of the α1 subunit. The exact mechanism of action of nitrendipine is unknown, but it is believed to have important tyrosine and threonine residues in its binding pocket and its binding interferes with the voltage sensor and gating mechanism of the channel. Thought to have a domain-interface model of binding. In hypertension, the binding of nitrendipine causes a decrease in the probability of open -type calcium channels and reduces the influx of calcium. The reduced levels of calcium prevent smooth muscle contraction within these muscle cells. Prevention of muscle contraction enables smooth muscle dilation. Dilation of the vasculature reduces total peripheral resistance, which decreases the workload on the heart and prevents scarring of the heart or heart failure.

In December as Emma's first pregnancy progressed, Charles fell ill and accomplished little during the following year. He did accept a position on the Council of the Geographical Society in May 1840. In 1841 he became able to work for short periods a couple of days a week, and produced a paper on stones and debris being carried by ice floes, but his condition did not improve. Having consulted his father he began looking for a house in the countryside to escape a city suffering from economic depression and civil unrest. Owen was one of the few scientific friends to visit Darwin at this time, but Owen's opposition to any hint of Transmutation made Darwin keep quiet about his theories.

Because of the β(2,1) linkages, inulin is not digested by enzymes in the human alimentary system, contributing to its functional properties: reduced calorie value, dietary fiber, and prebiotic effects. Without color and odor, it has little impact on sensory characteristics of food products. Oligofructose has 35% of the sweetness of sucrose, and its sweetening profile is similar to sugar. Standard inulin is slightly sweet, while high-performance inulin is not. Its solubility is higher than the classical fibers. When thoroughly mixed with liquid, inulin forms a gel and a white creamy structure, which is similar to fat. Its three-dimensional gel network, consisting of insoluble submicron crystalline inulin particles, immobilizes a large amount of water, assuring its physical stability. It can also improve the stability of foams and emulsions.

The expansion of the Roman Empire was achieved through military force in nearly every case. Roman culture as a whole revolved around its military for both expansion and protection. Geographic areas on the outskirts of the empire were prone to attack and required heavy military presence. The constant barrage of attacks and the increase of expansion caused casualties. Due to attack there was a need for specialized medical care for these armies in order to keep them in operational status. The specialized form of care however, was not created until the time of Augustus (). Prior to this there is little information about the care of soldiers. It is assumed soldiers were self-reliant, treating their own wounds and caring for other ailments encountered. They would also turn to civilians for help throughout the villages they would come across. This was considered a custom of the time, and was quite common for households to take in wounded soldiers and tend to them. As time progressed, there was an increase in care for the wounded as hospitals appeared. The idea was held by the Romans that a healed soldier was better than a dead one and a healed veteran was better than a new recruit.

The first organized theories of socialist economics were significantly impacted by classical economic theory, including elements in Adam Smith, Robert Malthus and David Ricardo. In Smith there is a conception of a common good not provided by the market, a class analysis, a concern for the dehumanizing aspects of the factory system, and the concept of rent as being unproductive. Ricardo argued that the renting class was parasitic. This, and the possibility of a "general glut", an over accumulation of capital to produce goods for sale rather than for use, became the foundation of a rising critique of the concept that free markets with competition would be sufficient to prevent disastrous downturns in the economy, and whether the need for expansion would inevitably lead to war.

NeXTSTEP 3.x was later ported to PA-RISC- and SPARC-based platforms, for a total of four versions: NeXTSTEP/NeXT (for NeXT's own hardware), NeXTSTEP/Intel, NeXTSTEP/PA-RISC, and NeXTSTEP/SPARC. Although the latter three ports were not widely used, NeXTSTEP gained popularity at institutions such as First Chicago NBD, Swiss Bank Corporation, O'Connor and Company, and other organizations, owing to its programming model. The software was used by many U.S. government agencies, including the United States Naval Research Laboratory, the National Security Agency, the Advanced Research Projects Agency, the Central Intelligence Agency, and the National Reconnaissance Office. Some IBM PC clone vendors offered somewhat customized hardware solutions that were delivered running NeXTSTEP on Intel, such as the Elonex NextStation and the Canon object.station 41.

Many of the genome regulatory processes have been linked to the formation of G-quadruplex structures, attributable to the huge role it plays in DNA repair of apurinic/apyrimidinic sites also known as AP sites. A new technique to map AP sites has been developed known as AP-seq which utilizes a biotin-labeled aldehyde-reactive probe (ARP) to tag certain regions of the genome where AP site damage occurrence has been significant. Another genome-wide mapping sequencing method known as ChIP-sequencing, was utilized to map both; damage in AP sites, and the enzyme responsible for its repair, AP endonuclease 1 (APE1). Both of these genome-wide mapping sequencing methods, ChIP-sequencing and ARP, have indicated that AP site damage occurrence is nonrandom. AP site damage was also more prevalent in certain regions of the genome that contain specific active promoter and enhancer markers, some of which were linked to regions responsible for lung adenocarcinoma and colon cancer. AP site damage was found to be predominant in PQS regions of the genome, where formation of G-quadruplex structures is regulated and promoted by the DNA repair process, base excision repair (BER). Base excision repair processes in cells have been proved to be reduced with aging as its components in the mitochondria begin to decline, which can lead to the formation of many diseases such as Alzheimer's disease (AD). These G-quadruplex structures are said to be formed in the promoter regions of DNA through superhelicity, which favors the unwinding of the double helical structure of DNA and in turn loops the strands to form G-quadruplex structures in guanine rich regions. The BER pathway is signalled when it indicates an oxidative DNA base damage, where structures like, 8-Oxoguanine-DNA glycosylase 1 (OGG1), APE1 and G-quadruplex play a huge role in its repair. These enzymes participate in BER to repair certain DNA lesions such as 7,8-dihydro-8-oxoguanine (8-oxoG), which forms under oxidative stress to guanine bases.

Several systematic reviews and meta-analyses of multiple studies have described the associations of vitamin D deficiency with adverse outcomes in COVID-19. In the largest analysis, with data from 76 observational studies including almost two million adults, vitamin D deficiency or insufficiency significantly increased the susceptibility to becoming infected with COVID-19 and having severe COVID-19, with odds ratios of 1.5 and 1.9 respectively, but these findings had high risk of bias and heterogeneity. A two-fold greater mortality was found, but this analysis was less robust. These findings confirm smaller, earlier analyses, one of which, in reporting that people with COVID-19 tend to have lower 25(OH)D levels than healthy subjects, stated that the trend for associations with health outcomes was limited by the low quality of the studies and by the possibility of reverse causality mechanisms.

Electromagnetic (e.g. radio or light) waves are conceptually pure single frequency phenomena while pulses may be mathematically thought of as composed of a number of pure frequencies that sum and nullify in interactions that create a pulse train of the specific amplitudes, PRRs, base frequencies, phase characteristics, et cetera (See Fourier Analysis). The first term (PRF) is more common in device technical literature (Electrical Engineering and some sciences), and the latter (PRR) more commonly used in military-aerospace terminology (especially United States armed forces terminologies) and equipment specifications such as training and technical manuals for radar and sonar systems.

W. V. O. Quine's version of formative epistemology considers reasons for serious doubt about the fruitfulness of traditional philosophic study of scientific knowledge. These concerns are raised in light of the long attested incapacity of philosophers to find a satisfactory answer to the problems of radical scepticism, more particularly, to David Hume's criticism of induction. But also, because of the contemporaneous attempts and failures to reduce mathematics to pure logic by those in or philosophically sympathetic to The Vienna Circle. He concludes that studies of scientific knowledge concerned with meaning or truth fail to achieve the Cartesian goal of certainty. The failures in the reduction of mathematics to pure logic imply that scientific knowledge can at best be defined with the aid of less certain set-theoretic notions. Even if set theory's lacking the certainty of pure logic is deemed acceptable, the usefulness of constructing an encoding of scientific knowledge as logic and set theory is undermined by the inability to construct a useful translation from logic and set-theory back to scientific knowledge. If no translation between scientific knowledge and the logical structures can be constructed that works both ways, then the properties of the purely logical and set-theoretic constructions do not usefully inform understanding of scientific knowledge.

Topol has been involved with wireless medicine since its inception. He was the first physician to serve on CardioNet's Medical Advisory Board in 1999, the first dedicated wireless medicine company that performs real-time remote, continuous electrocardiogram rhythm monitoring. In 2007 he joined the Board of Sotera Wireless that has developed the first continuous non-invasive blood pressure monitoring device, which also captures all vital signs. In 2008 he forged a new educational program with Qualcomm and Scripps Health to train physicians in wireless medicine, a 2-year clinician scholar program: STSI Wireless Health Scholar. At the 2009 International Wireless CTIA meeting, he gave the keynote address on wireless health, the first time that topic was the subject of a CTIA plenary session. Also in 2009, he served as co-founder with Gary and Mary West to form the West Wireless Health Institute. He is the vice-chairman of the institute and its chief innovation officer. In 2009 he also presented at TEDMED the rapid progress being made in this field. In addition, in early 2010 Topol gave a wireless medicine presentation at the Consumer Electronic Show. He led the first trial with the GE Vscan device GE Reports, a pocket high resolution, mobile ultrasound imaging device, introduced in the US in 2010 "The Doctor Will “e” You Now" and is currently leading clinical trials of heart rhythm and heart failure monitoring wireless devices.

The desktop computer market was long dominated by PC hardware using the x86/x86-64 instruction set and GPUs available for the PC. With three major competitors (Nvidia, AMD and Intel). The main competing factor was the price of hardware and raw performance in 3D computer games, which is greatly affected by the efficient translation of API calls into GPU opcodes. The display driver and the video decoder are inherent parts of the graphics card: hardware designed to assist in the calculations necessary for the decoding of video streams. As the market for PC hardware has dwindled, it seems unlikely that new competitors will enter this market and it is unclear how much more knowledge one company could gain by seeing the source code of other companies' drivers.

Because of TiN's metallic gold color, it is used to coat costume jewelry and automotive trim for decorative purposes. TiN is also widely used as a top-layer coating, usually with nickel (Ni) or chromium (Cr) plated substrates, on consumer plumbing fixtures and door hardware. As a coating it is used in aerospace and military applications and to protect the sliding surfaces of suspension forks of bicycles and motorcycles as well as the shock shafts of radio controlled cars. TiN is also used as a protective coating on the moving parts of many rifles and semi automatic firearms, as it is extremely durable. As well as being durable, it is also extremely smooth, making removing the carbon build up extremely easy. TiN is non-toxic, meets FDA guidelines and has seen use in medical devices such as scalpel blades and orthopedic bone saw blades where sharpness and edge retention are important. TiN coatings have also been used in implanted prostheses (especially hip replacement implants) and other medical implants.

Georgia Military College was created in 1879 by act of the Georgia General Assembly "to educate young men and women from the Middle Georgia area in an environment which fosters the qualities of good citizenship." It was the apparent intention of the General Assembly to establish the school as a unit of the slowly forming University System of Georgia. State property in Milledgeville, including the former state capital building which had been damaged by General William T. Sherman's "March to the Sea", was loaned to the University of Georgia by the Act of 1879, and the Board of Trustees of the University of Georgia was given veto powers by this Act over the acts of the local Board of Trustees of the new institution. The school was originally called Middle Georgia Military and Agricultural College and was ceded state government lands surrounding the Old Capitol Building, the seat of government for the state of Georgia from 1807–1868. The Old Capitol Building, then as now, is the main college facility and sits on the highest point in Milledgeville. Former Confederate general Daniel Harvey Hill served as president from 1885 until August 1889, when he resigned due to failing health. (He died in Charlotte, NC on September 24, 1889.) The 1890 graduating class was the first to include female students.

This division was charged with understanding how ionizing radiation interacts with living things and to try to find ways to help them survive radiation damage, such as bone marrow transplants. In the 1960s Weinberg also pursued new missions for ORNL, such as using nuclear energy to desalinate seawater. He recruited Philip Hammond from the Los Alamos National Laboratory to further this mission and in 1970 started the first big ecology project in the United States: the National Science Foundation – Research Applied to National Needs Environmental Program.

The microscopic property that imbues material substances with a temperature can be readily understood by examining the ideal gas law, which relates, per the Boltzmann constant, how heat energy causes precisely defined changes in the pressure and temperature of certain gases. This is because monatomic gases like helium and argon behave kinetically like freely moving perfectly elastic and spherical billiard balls that move only in a specific subset of the possible motions that can occur in matter: that comprising the "three translational" degrees of freedom. The translational degrees of freedom are the familiar billiard ball-like movements along the X, Y, and Z axes of 3D space (see "Fig. 1", below). This is why the noble gases all have the same specific heat capacity per atom and why that value is lowest of all the gases.

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. The entry points in the host cell are through certain cell receptors. One receptor that the virus will bind is surface immunoglobulin M, which specifically interacts with the light chains of the antibody. Another receptor that can be bound is heat shock protein 90 (HSP90) on the surface of the DF-1 cell membrane. Although, this receptor will bind either the virus or the VP2-viral sub particle. Entry through the membrane has not been fully understood. The penetration of the membrane is aided by the capsid PEP46. The capid will have a peptide generated from the c-terminal of pVP2 that is released by VP4. The peptide causes the membrane to become permeable by forming pores, which allow for PEP46 entry depending on calcium gradient. If the inner calcium gradient is low, then it is thought to enter V-ATPase positive vesicles by endocytosis and uncoated for entry into the cytosol. Also, it has been found VP2-α4β1 aids in spreading the virus in the cell as well through macropinocytosis. This will allow for the virus to be moved to the early endosomes that is accomplished in the cell through Rab5. Replication follows the double-stranded RNA virus replication model. Double-stranded rna virus transcription is the method of transcription. Young chickens and other fowl serve as the natural host. Transmission routes are contamination.

Administrative reforms during the 19th century included the replacement of oral examinations with written entrance tests, greater tolerance for religious dissent, and the establishment of four women's colleges. Privy Council decisions in the 20th century (e.g. the abolition of compulsory daily worship, dissociation of the Regius Professorship of Hebrew from clerical status, diversion of colleges' theological bequests to other purposes) loosened the link with traditional belief and practice. Furthermore, although the university's emphasis had historically been on classical knowledge, its curriculum expanded during the 19th century to include scientific and medical studies. Knowledge of Ancient Greek was required for admission until 1920, and Latin until 1960.

One particular study used patients with focal lesions on the basal ganglia (specifically the putamen) due to stroke in order to study category learning. The advantage to using these types of patients is that dopaminergic projections to the prefrontal cortex are more likely to be intact. Also, in these patients, it is easier to relate specific brain structures to function because the lesion only occurs in a specific place. The goal of this study was to determine whether or not these lesions affect rule-based and information-integration task learning. Rule-based tasks are learned via hypothesis-testing dependent on working memory. Information-integration tasks are ones wherein the accuracy is maximized when information from two sources are integrated at a pre-decisional stage, which follows a procedural-based system.

Hansma and Peterson have discussed determining the combined effects of defocus and diffraction using a root-square combination of the individual blur spots. Hansma's approach determines the f-number that will give the maximum possible sharpness; Peterson's approach determines the minimum f-number that will give the desired sharpness in the final image, and yields a maximum depth of field for which the desired sharpness can be achieved. In combination, the two methods can be regarded as giving a maximum and minimum f-number for a given situation, with the photographer free to choose any value within the range, as conditions (e.g., potential motion blur) permit. Gibson gives a similar discussion, additionally considering blurring effects of camera lens aberrations, enlarging lens diffraction and aberrations, the negative emulsion, and the printing paper. Couzin gave a formula essentially the same as Hansma's for optimal "f"-number, but did not discuss its derivation.

In close collaboration with the internist Joseph Škoda he made clear the relationships between clinical symptoms that can be seen, felt or heard and pathological changes to organs, i.e. clinico-pathological correlation. Thus it was now possible for the first time to make scientifically sound diagnoses. Rokitansky thus initiated a paradigm shift from speculative, natural-philosophical medicine to systematic, science-based medicine. By classifying illnesses according to their stage of progression, it became possible to diagnose how far a pathological condition had advanced and to deliver a prognosis. From the 1830s onwards medical students and physicians from all over the world came to Vienna to learn about Rokitansky's diagnostic methods and nosology, which soon became known internationally as the Young or New Viennese School.

Polystyrene generally has stiffness, transparency, processibility, and dielectric qualities that make it useful. However, its low impact resistance at low temperatures makes catastrophic fracture failure when cold more likely. The most widely used version of toughened polystyrene is called high impact polystyrene or HIPS. Being cheap and easy to thermoform (see "thermoforming"), it is utilized for many everyday uses. HIPS is made by polymerizing styrene in a polybutadiene rubber solution. After the polymerization reaction begins, the polystyrene and rubber phases separate. When phase separation begins, the two phases compete for volume until phase inversion occurs and the rubber can distribute throughout the matrix. The alternative emulsion polymerization with styrene-butadiene-styrene or styrene-butadiene copolymers allows fine-tuned manipulation of particle size distribution. This method makes use of the core-shell architecture.

Richard Trevithick had already used a return flue with his first 1802 Coalbrookdale locomotive design and 1804 Pen-y-darren engine. These boilers were heavily built of cast iron, short and flat-ended. His 1804/5 "Newcastle" locomotive (actually built in Gateshead) began to show one characteristic feature of the return-flued boiler, a prominent dome shape to resist steam pressure in the solid end opposite both furnace and chimney. In this case, the boilermaking, now of wrought iron plates, must have been complicated by Trevithick's single long-travel horizontal cylinder ( diameter×stroke) which emerged through this domed end. This did make work easier for the fireman though, as he was no longer trying to reach a firedoor beneath the long crosshead of the piston.

In the fall of 2016, the U.S. House Committee on Oversight and Government Reform held a briefing to ask officials from the National Institutes of Health (NIH) about NIH's grant funding to the IARC. The NIH grant database showed that it has given the IARC over $1.2 million in 2016. Jason Chaffetz (Republican) asked the NIH to give his committee details of its standards for awarding grants and vetting grant nominees. Additionally, Congressman Robert Aderholt (Republican), chairman of the House Appropriations Subcommittee on Agriculture, wrote a letter in June 2016 to the head of the NIH questioning the funding of IARC. Republican congressman Jason Chaffetz argued that the IARC is too prone to conclude that substances are carcinogenic. However, IARC respond that the Working Groups methods are "widely respected for their scientific rigor, standardized and transparent process and for freedom from conflicts of interest." Director of IARC Chris Wild further added that the IARC only chooses substances to evaluate from which there already exists a body of scientific literature that says there is a carcinogenic risk to humans. Wild said that because IARC does not select substances at random, it has a low rate of determining a substance as not being cancer-causing.

As microelectronics evolves into nanoelectronics, it is essential to perform electronic transport measurements at nanoscale. The standard approach is to use lithographic methods to contact nanostructures, as it is also used in the final nanoelectronic device. In research and development stages, however, other methods to contact nanoelectronic devices or generally nanostructures may be more suitable. An alternative approach for contacting nanostructures uses the tips of a multi-tip scanning tunneling microscope—in analogy to the test leads of a multimeter used at macroscale. The advantages of this approach are: (a) "in situ" contacting of ″as grown″ nanostructures still under vacuum helps keep delicate nanostructures free from contamination induced by lithography steps performed for contacting. (b) Flexible positioning of the contacting tips and different contact configurations are easy to realize, while lithographic contacts are fixed. (c) Probing with sharp tips can be non-invasive (high ohmic), while lithographic contacts are typically invasive (low ohmic). To use a scanning tunneling microscope (STM) for electrical transport measurements at nanostructures or at surfaces, more than one tip is required. This motivates the use of multi-tip scanning tunneling microscopes which give access to the above outlined advantages in nanoprobing. Several review articles about multi-tip STM can be found in the "further reading" section below.

Later an agreement with the Merchant Venturers was made with the organisation being merged with the college's Engineering Department to create a new Faculty of Engineering. All teaching was to take place in the Merchant Venturers Building. The principal Julius Wertheimer was left with little bargaining power after the destruction of his own institutions buildings. As government funding was linked to endowment this massive endowment created further wealth for the college. Later in 1908 a petition was presented to the Privy Council representing the views of the University Committee. On 24 May 1909 Bristol University, as it then became known, gained its royal charter allowing it to award degrees after the king in Privy Council assented to the creation of a university. Flags were flown from public buildings in Bristol and the city's church bells hang out on receiving the news.

Bioremediation is the process of decontaminating polluted sites through the usage of either endogenous or external microorganism. In situ is a term utilized within a variety of fields meaning "on site" and refers to the location of an event. Within the context of bioremediation, in situ indicates that the location of the bioremediation has occurred at the site of contamination without the translocation of the polluted materials. Bioremediation is used to neutralize pollutants including Hydrocarbons, chlorinated compounds, nitrates, toxic metals and other pollutants through a variety of chemical mechanisms. Microorganism used in the process of bioremediation can either be implanted or cultivated within the site through the application of fertilizers and other nutrients. Common polluted sites targeted by bioremediation are groundwater/aquifers and polluted soils. Aquatic ecosystems affected by oil spills have also shown improvement through the application of bioremediation. The most notable cases being the "Deepwater Horizon" oil spill in 2010 and the Exxon Valdez oil spill in 1989. Two variations of bioremediation exist defined by the location where the process occurs. Ex situ bioremediation occurs at a location separate from the contaminated site and involves the translocation of the contaminated material. In situ occurs within the site of contamination In situ bioremediation can further be categorized by the metabolism occurring, aerobic and anaerobic, and by the level of human involvement.

In 2021, following "Nature's" 2019 publication of anomalous findings that might only be explained by some localized fusion, scientists at the Naval Surface Warfare Center, Indian Head Division announced that they had assembled a group of scientists from the Navy, Army and National Institute of Standards and Technology to undertake a new, coordinated study. With few exceptions, researchers have had difficulty publishing in mainstream journals. The remaining researchers often term their field Low Energy Nuclear Reactions (LENR), Chemically Assisted Nuclear Reactions (CANR), Lattice Assisted Nuclear Reactions (LANR), Condensed Matter Nuclear Science (CMNS) or Lattice Enabled Nuclear Reactions; one of the reasons being to avoid the negative connotations associated with "cold fusion". The new names avoid making bold implications, like implying that fusion is actually occurring.

On March 28, 2011, a supermassive black hole was seen tearing a mid-size star apart. That is the only likely explanation of the observations that day of sudden X-ray radiation and the follow-up broad-band observations. The source was previously an inactive galactic nucleus, and from study of the outburst the galactic nucleus is estimated to be a SMBH with mass of the order of a . This rare event is assumed to be a relativistic outflow (material being emitted in a jet at a significant fraction of the speed of light) from a star tidally disrupted by the SMBH. A significant fraction of a solar mass of material is expected to have accreted onto the SMBH. Subsequent long-term observation will allow this assumption to be confirmed if the emission from the jet decays at the expected rate for mass accretion onto a SMBH.
