Minor uses of ethylene glycol include the manufacture of capacitors, as a chemical intermediate in the manufacture of 1,4-dioxane, as an additive to prevent corrosion in liquid cooling systems for personal computers, and inside the lens devices of cathode-ray tube type of rear projection televisions. Ethylene glycol is also used in the manufacture of some vaccines, but it is not itself present in these injections. It is used as a minor (1–2%) ingredient in shoe polish and also in some inks and dyes. Ethylene glycol has seen some use as a rot and fungal treatment for wood, both as a preventative and a treatment after the fact. It has been used in a few cases to treat partially rotted wooden objects to be displayed in museums. It is one of only a few treatments that are successful in dealing with rot in wooden boats, and is relatively cheap. Ethylene glycol may also be one of the minor ingredients in screen cleaning solutions, along with the main ingredient isopropyl alcohol. Ethylene glycol is commonly used as a preservative for biological specimens, especially in secondary schools during dissection as a safer alternative to formaldehyde. It is also used as part of the water-based hydraulic fluid used to control subsea oil and gas production equipment.

In the early Cretaceous, approximately 130 million years ago, there was a major diversification of angiosperms that set in motion a large evolutionary change in high paleolatitude forest composition. The diversification of angiosperms is in close connection with pollen and nectar collecting insects. It is thought that the diversification of these insects would have a substantial impact on the rate of angiosperm speciation. Whatever the mechanism for the diversification, the early Cretaceous angiosperm "takeover" denotes an important transition of the ecosystem. By the end of the Cretaceous, the composition of polar forest regions had diversified by approximately 50-80%. This transition from conifers, cycads and ferns to predominantly angiosperms reflects an interesting evolutionary adaptation to the regional polar climate and quite possibly numerous other factors like sea-floor spreading rates, eustatic sea level and high global temperatures.

In 1948, Roger and Colette Vendrely reported a "remarkable constancy in the nuclear DNA content of all the cells in all the individuals within a given animal species", which they took as evidence that DNA, rather than protein, was the substance of which genes are composed. The term C-value reflects this observed constancy. However, it was soon found that C-values (genome sizes) vary enormously among species and that this bears no relationship to the "presumed" number of genes ("as reflected by" the complexity of the organism). For example, the cells of some salamanders may contain 40 times more DNA than those of humans. Given that C-values were assumed to be constant because genetic information is encoded by DNA, and yet bore no relationship to presumed gene number, this was understandably considered paradoxical; the term "C-value paradox" was used to describe this situation by C.A. Thomas Jr. in 1971.

A controlled environment can protect metals from polluted air, dust, ultraviolet radiation, and excessive relative humidity - ideal values are temperature of 16-20 °C and up to 40% (35-55% according to recent Canadian Conservation Institute recommendations) relative humidity, noting that if metal is combined with organic materials, relative humidity should not be below 45%. Archaeological objects are best stored in rooms (or plastic boxes) with very low relative humidity, except if they come from a bog or high water environment, in which case the right equilibrium with the environment needs to be found. Particularly valuable items can be placed in sealed micro-climate containers with an inert gas such as nitrogen or argon. Metals with active corrosion fare better with lower relative humidity: copper or copper alloy objects up to 35% RH and iron objects 12-15% RH.

A chromatoid body is a dense structure in the cytoplasm of male germ cells. It is composed mainly of RNAs and RNA-binding proteins and is thus a type of RNP granule. Chromatoid body-like granules first appear in spermatocytes and condense into a single granule in round spermatids. The structure disappears again when spermatids start to elongate. The chromatoid body is crucial for spermatogenesis but its exact role in the process is not known. Following significant strides in the understanding of small non-coding RNA mediated gene regulation and PIWI-interacting RNAs (piRNA) and their roles in germline development, the function of Chromatoid Bodies (CB) has been somewhat elucidated. However, due to similarities with RNP granules found in somatic cells – such as stress granules and processing bodies – chromatoid body is thought to be involved in post-transcriptional regulation of gene expression. Postmeiotic germ cell differentiation induces the accumulation of piRNAs and proteins of piRNA machinery along with several distinct RNA regulator proteins. Although evidence suggests CB involvement in mRNA regulation and small RNA mediated gene regulation, the mechanism of action remains obscure.

The phase-in way is to pass a law permitting the use of metric units in parallel with traditional ones, followed by education of metric units, then progressively ban the use of the older measures. This has generally been a slow route to metric. The British Empire permitted the use of metric measures in 1873, but the changeover was not completed in most Commonwealth countries other than India and Australia until the 1970s and 1980s when governments took an active role in metric conversion. In the United Kingdom and Canada, the process is still incomplete. Japan also followed this route and did not complete the changeover for 70 years. By law, loose goods sold with reference to units of quantity have to be weighed and sold using the metric system. In 2001, the EU directive 80/181/EEC stated that supplementary units (imperial units alongside metric including labelling on packages) would become illegal from the beginning of 2010. In September 2007, a consultation process was started which resulted in the directive being modified to permit supplementary units to be used indefinitely.

Nishihara and coworkers studied the clinical features of subacute thyroiditis in 852 mostly 40- to 50-year-old women in Japan. They noted seasonal clusters (summer to early autumn) and most subjects presented with neck pain. Fever and symptoms of thyrotoxicosis were present in two thirds of subjects. Upper respiratory tract infections in the month preceding presentation were reported in only 1 in 5 subjects. Recurrent episodes following resolution of the initial episode were rare, occurring in just 1.6% of cases. Laboratory markers for thyroid inflammation and dysfunction typically peaked within one week of onset of illness.

On 9 September 1976, Asli Hassan Abade soloed her first flight as the only female pilot in the Somali Air Force. In 1977, Cheryl Pickering-Moore and Beverley Drake of Guyana became the first two women pilots of the Guyana Defence Force. Drake was transferred a few months later as the first female pilot of the Guyana Airways Corporation, she would go on in the 1990s to become the first woman and African-American senior inspection analyst working for the U.S. National Transportation Safety Board. Jill Brown-Hiltz joined Texas International Airlines as a pilot in 1978, becoming the first African American woman to fly for a commercial airline in the United States. That same year, Chinyere Kalu, at the time Chinyere Onyenucheya became, Nigeria's first female pilot. In 1979, Koh Chai Hong became the first woman pilot in the Republic of Singapore Air Force (RSAF). Continuing her military career, Koh became one of the first two female Lieutenant-Colonels in 1999. Bahamian Patrice Clarke, later Washington, entered Embry–Riddle Aeronautical University, Daytona Beach in 1979. Three years later she would become the school's first black woman to graduate with a BS in aeronautical science and her commercial pilot's certification. She would go on to become the first woman pilot hired by Bahamasair and later the first black female to command airplanes in the U.S. for a major carrier service when she was promoted to captain by United Parcel Service (UPS) in 1994.

In the mid-1990s development of both, residential and commercial rooftop solar as well as utility-scale photovoltaic power stations began to accelerate again due to supply issues with oil and natural gas, global warming concerns, and the improving economic position of PV relative to other energy technologies. In the early 2000s, the adoption of feed-in tariffs—a policy mechanism, that gives renewables priority on the grid and defines a fixed price for the generated electricity—led to a high level of investment security and to a soaring number of PV deployments in Europe.

His paper "Artificial Evolution for Computer Graphics" described the application of genetic algorithms to generate abstract 2D images from complex mathematical formulae, evolved under the guidance of a human. He used this method to create the video "Primordial Dance" – which, according to one published study with supplementary video, calls to mind the history of early 20th century abstraction among its several evolutionary themes – as well as parts of "Liquid Selves". "Genetic Images" was an interactive installation also based on this method; it was exhibited at the Centre Georges Pompidou in Paris, 1993, as well as Ars Electronica and the Los Angeles Interactive Media Festival.

The 1935–36 season would turn out to be Craig Ruby's 14th and final year of coaching at the University of Illinois. It would also turn out to be Ruby's final head coaching job anywhere as he would leave to pursue a career with Hallmark Greeting Cards. Ruby's tenure at Illinois ranks 3rd behind Lou Henson (21 years) and Harry Combes (20 years). His 148 wins also ranks 5th behind Henson (423) Combes (316) and Bruce Weber (210) and Doug Mills (151). Along with future head coach Harry Combes, the Illini returned 10 lettermen from a team that had finished in first place in the Big Ten the year before. Unfortunately for the Illini, they lost 3 conference games at home and finished with a record of 7 wins and 5 losses. The team finished the season with an overall record of 13 wins 6 losses. The starting lineup included "captain" Howard Braun and Wilbur Henry at guard, Harry Combes, Harold Benham and James Vopicka at forward, with Robert Riegel at the center position.

The redshifting for a particular quasar provides temporal (time) information about reionization. Since an object's redshift corresponds to the time at which it emitted the light, it is possible to determine when reionization ended. Quasars below a certain redshift (closer in space and time) do not show the Gunn-Peterson trough (though they may show the Lyman-alpha forest), while quasars emitting light prior to reionization will feature a Gunn-Peterson trough. In 2001, four quasars were detected (by the Sloan Digital Sky Survey) with redshifts ranging from "z" = 5.82 to "z" = 6.28. While the quasars above "z" = 6 showed a Gunn-Peterson trough, indicating that the IGM was still at least partly neutral, the ones below did not, meaning the hydrogen was ionized. As reionization is expected to occur over relatively short timescales, the results suggest that the universe was approaching the end of reionization at "z" = 6. This, in turn, suggests that the universe must still have been almost entirely neutral at "z" > 10.

In control theory and stability theory, the Nyquist stability criterion or Strecker–Nyquist stability criterion, independently discovered by the German electrical engineer at Siemens in 1930 and the Swedish-American electrical engineer Harry Nyquist at Bell Telephone Laboratories in 1932, is a graphical technique for determining the stability of a dynamical system. Because it only looks at the Nyquist plot of the open loop systems, it can be applied without explicitly computing the poles and zeros of either the closed-loop or open-loop system (although the number of each type of right-half-plane singularities must be known). As a result, it can be applied to systems defined by non-rational functions, such as systems with delays. In contrast to Bode plots, it can handle transfer functions with right half-plane singularities. In addition, there is a natural generalization to more complex systems with multiple inputs and multiple outputs, such as control systems for airplanes.

In "Rhodobacter sphaeroides", PRK (or RsPRK) exists as a homooctomer with protomers composed of seven-stranded mixed β-sheets, seven α-helices, and an auxiliary pair of anti-parallel β-strands. The RsPRK subunit exhibits a protein folding analogous to the folding of nucleotide monophosphate (NMP) kinases. Mutagenesis studies suggest that either Asp 42 or Asp 169 acts as the catalytic base that deprotonates the O1 hydroxyl oxygen on RuP for nucleophilic attack of ATP, while the other acts a ligand for a metal cation like Mg (read mechanism below for more details). Other residues present at the active site for RsPRK include His 45, Arg 49, Arg 168, and Arg 173, which are purportedly involved in RuP binding. (See image at right).

The program above scales poorly because the loop that distributes information executes sequentially. Writing scalable programs often requires a sophisticated understanding of parallel algorithms, a detailed knowledge of the underlying network characteristics, and special tuning for application characteristics such as the size of data transfers. For most application developers, letting the compiler or runtime library decide the best algorithm proves more robust and high-performing. Fortran 2018 will offer collective communication subroutines that empower compiler and runtime library teams to encapsulate efficient parallel algorithms for collective communication and distributed computation in a set of collective subroutines. These subroutines and other new parallel programming features are summarized in a technical specification that the Fortran standards committee has voted to incorporate into Fortran 2018. These enable the user to write a more efficient version of the above algorithm

After World War II, and with the onset of Cold War tensions, the US continued its clandestine wartime bio-weapons program. The Korean War (1950–53) added justification for continuing the program, when the possible entry of the Soviet Union into the war was feared. Concerns over the Soviet Union were justified, for the Soviet Union would pronounce in 1956 that chemical and biological weapons would, indeed, be used for mass destruction in future wars. In October 1950, the US Secretary of Defense approved continuation of the program, based largely on the Soviet threat and a belief that the North Korean and Chinese communists would use biological weapons. With expansion of the biological warfare retaliatory program, the scope of the defensive program was nearly doubled. Data were obtained on personnel protection, decontamination, and immunization. Early detection research produced prototype alarms for use on the battlefield, but progress was slow, apparently limited by technology.

In Spring 1983, at age 38, he was arrested in Allentown, Pennsylvania after police found him in his car, holding a pistol, which was a violation of his parole terms. On May 3, 1983, he attempted a failed escape from prison in Allentown, breaking his leg in the process. Later that year, he was tried and convicted for indecent assaults, robbery, criminal trespassing and sentenced to 2 1/2 years to 5 years in Pennsylvania prison. He served five years in Graterford State Prison in Skippack Township, Pennsylvania. Following completion of his Pennsylvania sentence in 1988 at age 43, he was moved to Big Muddy River Correctional Center in Ina, Illinois to complete sentencing terms for parole violations and violating his prior conditional release terms. There, he chose to remain in prison, saying he did not wish to hurt anyone. He also ceased attempting to convince officials that he wished to change his criminal ways, and he stopped attending prison therapy sessions. He remained in prison for nearly 20 years, from the age of 42 to 62.

In her dissertation, Prosser argues that racial injustices and feelings of isolation have damaging effects on the psyche of Black children. The effects are even more detrimental with the standards of living as it applies to socioeconomic status. Given that her sample size was small (64 students), Prosser refrained from making absolute suggestions. She argued that school selection should be based on the student's personality, as some do well in integrated schools while others benefit from segregated schools. She believed that most Black students receive a more balanced curriculum, affection, support, and family-school consistency in segregated schools. She also noted that segregated schools not only provided job opportunities, but also "a more nurturing environment" for Black teachers as well as students. Her work was essential in proving the benefit of predominantly black school as well as HBCU's to the black psyche. In 2010, the International's Encyclopedia of Education published an article highlighting the myriad of positive benefits Black students receive in these segregated institutions. Prosser's tests concluded that Black children who went to mixed schools were more secluded, felt much more inferior at school and had trouble adjusting social, both with teachers, other students, and with family. They supported these institutions as "safe spaces" for black students to fortify their sense of self amidst the marginalization they face.

Roman law addressed the rape of a male citizen as early as the 2nd century BC, when it was ruled that even a man who was "disreputable and questionable" ("famosus," related to "infamis", and "suspiciosus)" had the same right as other free men not to have his body subjected to forced sex. The "Lex Julia de vi publica", recorded in the early 3rd century AD but probably dating from the dictatorship of Julius Caesar, defined rape as forced sex against "boy, woman, or anyone"; the rapist was subject to execution, a rare penalty in Roman law. Men who had been raped were exempt from the loss of legal or social standing suffered by those who submitted their bodies to use for the pleasure of others; a male prostitute or entertainer was "infamis" and excluded from the legal protections extended to citizens in good standing. As a matter of law, a slave could not be raped; he was considered property and not legally a person. The slave's owner, however, could prosecute the rapist for property damage.

In the 1990s, with the onset of market reforms, agricultural output collapsed, and rural agricultural areas continued to decline in productivity, though they were not alone in this lack of output as urban centers began to suffer in terms of manufacturing, but at an even higher rate. This was not only alarming because never had such a statistic revealed itself, but also because the agricultural realm was so dependent on the consistency of the urban realm for its own survival that such a decline would prove harmful to both spheres. The dramatic crop failure of 1998 that Siberia experienced did not help the situation either. Subsidiary farming, a form of farming executed by small-town inhabitants in their private yards, began to rise during this period further proving a regression in rural production. The institution of subsidiary farming represented a serious step back in terms of modern development.

Unlike its predecessor DFZ/DFR, the Cosworth HB was hardly ever used outside of Formula 1. After the FIA had allowed 3.5-liter naturally aspirated engines for the 1991 season of the sports car world championship as part of extensive rule changes, aggregates from the Formula 1 can be adopted with a few changes. Accordingly, Tom Walkinshaw Racing then installed an HB-III engine in its Group C Jaguar XJR-14 sports car. The cars won the 1991 430 km Monza race, the Silverstone, and the 430 km Nürburgring race. At the 1991 Le Mans 24 HoursHowever, Walkinshaw decided not to use the XJR-14 because the engine was not believed to be capable of 24-hour continuous operation without problems. In 1992 XJR-14s were then driven in the IMSA GTP series. Davy Jones won the championship rounds at Road Atlanta and Mid-Ohio with this Jaguar model.

Cleaves sprained his ankle with 16:18 to play in the second half, and this was after Florida had trimmed Michigan State's double digit halftime lead to 50–44. Cleaves returned about four minutes later, and immediately helped lead the Spartans on a 16–6 run to put the game out of reach. The lone top-seed remaining would bring order to a tournament filled with upsets as they salted away the victory for the school's second National Championship (1979).

However, performance testing is frequently not performed against a specification; e.g., no one will have expressed what the maximum acceptable response time for a given population of users should be. Performance testing is frequently used as part of the process of performance profile tuning. The idea is to identify the "weakest link" – there is inevitably a part of the system which, if it is made to respond faster, will result in the overall system running faster. It is sometimes a difficult task to identify which part of the system represents this critical path, and some test tools include (or can have add-ons that provide) instrumentation that runs on the server (agents) and reports transaction times, database access times, network overhead, and other server monitors, which can be analyzed together with the raw performance statistics. Without such instrumentation one might have to have someone crouched over Windows Task Manager at the server to see how much CPU load the performance tests are generating (assuming a Windows system is under test).

The Mezen River basin is located in northern Russia and has extensive exposures of Middle Permian sediments along the edges of affluent rivers of the Mezen River. These sediments have produced many skeletal remains of diverse amniotes, but most importantly, a partial skull of “a small synapsid of varanopseid affinities”, "Mesenosaurus romeri". "M. romeri" was discovered in 1938 by Ivan Efremov and became the first species of Mesenosaurus, due to its lack of cranial similarities to others. It was also the first reptile described from the Russian area to be considered a “good pelycosaur”, as it possessed upper jaw teeth that were consistent with other known pelycosaurs (slender, recurved, enlarged incisors, single caniniform tooth). Romer and Price hypothesized that "M. romeri" belonged to Varanopseidae. This hypothesis was confirmed in 2001 based on the following synapomorphies:

Aside from its use to supply medical oxygen, or as a substitute for bulk cryogenic or compressed-cylinder storage, which is the primary oxygen source for any hospital, PSA has numerous other uses. One of the primary applications of PSA is in the removal of carbon dioxide (CO) as the final step in the large-scale commercial synthesis of hydrogen (H) for use in oil refineries and in the production of ammonia (NH). Refineries often use PSA technology in the removal of hydrogen sulfide (HS) from hydrogen feed and recycle streams of hydrotreating and hydrocracking units. Another application of PSA is the separation of carbon dioxide from biogas to increase the methane (CH) ratio. Through PSA the biogas can be upgraded to a quality similar to natural gas. This includes a process in landfill gas utilization to upgrade landfill gas to utility-grade high purity methane gas to be sold as natural gas.

In 1992, after occupying the site for 84 years, the Christian Brothers vacated Mount St Mary. A Feast Day in honour of the Blessed Virgin was held in the Barron Chapel on 15 August 1992. On 3 September, a final mass was celebrated in the Gothic chapel and on 14 September, the last Brothers left Mount St Mary. In July 1993 the Provincial of the Christian Brothers commented on Mount St Mary as an:"institution that has shaped and set some 3,000 of us on the road to a life of education of and service to the youth of this country. Mount St Mary has become a symbol of nurture and support, of stability and fidelity for Christian Brothers and their associates who accepted the challenge of considerable involvements in Catholic Education - in this country over the last 150 years."D.M. Stewart wrote:"The Brothers' community and administrative offices had indeed been transferred elsewhere but there remained on site many memorials to the Christian Brothers' presence and labours. The fine Romanesque chapel is known as the Barron Chapel after the great Jerome Barron while the altar commemorates Brother Ambrose Treacy, the founder of the Australasian province. Then there are buildings or lecture rooms named after others such as the Murray Hall, the Mullen Building, the Marwell Building, the McGlade, Duffy and Hanrahan lecture rooms, while Davy is associated with the Dan Stewart Library. . . Brothers and former students still like to return to Mount Saint Mary, to enjoy its beauty, its peace and to savour again something of the spirit that hopefully inspires the staff and students to whom has been entrusted a rich tradition that is now part of the Australian Catholic University."

Inadequately secured hardware can be subject to physical tampering. Some critics, such as the group "Wij vertrouwen stemcomputers niet" ("We do not trust voting machines"), charge that, for instance, foreign hardware could be inserted into the machine, or between the user and the central mechanism of the machine itself, using a man in the middle attack technique, and thus even sealing DRE machines may not be sufficient protection. This claim is countered by the position that review and testing procedures can detect fraudulent code or hardware, if such things are present, and that a thorough, verifiable chain of custody would prevent the insertion of such hardware or software. Security seals are commonly employed in an attempt to detect tampering, but testing by Argonne National Laboratory and others demonstrates that existing seals can usually be quickly defeated by a trained person using low-tech methods.

CDKN2A, also known as cyclin-dependent kinase inhibitor 2A, is a gene which in humans is located at chromosome 9, band p21.3. It is ubiquitously expressed in many tissues and cell types. The gene codes for two proteins, including the INK4 family member p16 (or p16INK4a) and p14arf. Both act as tumor suppressors by regulating the cell cycle. p16 inhibits cyclin dependent kinases 4 and 6 (CDK4 and CDK6) and thereby activates the retinoblastoma (Rb) family of proteins, which block traversal from G1 to S-phase. p14ARF (known as p19ARF in the mouse) activates the p53 tumor suppressor. Somatic mutations of CDKN2A are common in the majority of human cancers, with estimates that CDKN2A is the second most commonly inactivated gene in cancer after p53. Germline mutations of CDKN2A are associated with familial melanoma, glioblastoma and pancreatic cancer. The "CDKN2A" gene also contains one of 27 SNPs associated with increased risk of coronary artery disease.

the IBM 350 and similar drives. The 1301 consisted of one (for Model 1) or two (for model 2) modules, each containing 25 platters, each platter about thick and in diameter. While the earlier IBM disk drives used only two read/write heads per arm, the 1301 used an array of 48 heads (comb), each array moving horizontally as a single unit, one head per surface used. Cylinder-mode read/write operations were supported, and the heads flew about 250 micro-inches (about 6 µm) above the platter surface. Motion of the head array depended upon a binary adder system of hydraulic actuators which assured repeatable positioning. The 1301 cabinet was about the size of three home refrigerators placed side by side, storing the equivalent of about 21 million eight-bit bytes per module. Access time was about a quarter of a second.

Some materials in nature act as ready made "building blocks" to the animals in question, such as feathers and leaf petioles for some birds and animal hair for the chaffinch. Other materials need to be "processed". Caddisfly larvae use stone pieces and also cut sections from green leaves for use in construction. The stone pieces are selected as per their size and shape from a large variety. In the case of leaf sections, these are cut and shaped to required size. Similarly bagworms cut and shape thorns or twigs to form their case. Some sphecid wasps collect mud and blend them with water to construct free standing nests of mud.

From 1788 until 1870 the defence of the Australian colonies was mostly provided by British Army regular forces. Originally Marines protected the early settlements at Sydney Cove and Norfolk Island, however they were relieved of these duties in 1790 by a British Army unit specifically recruited for colonial service, known as the New South Wales Corps. The New South Wales Corps subsequently was involved in putting down a rebellion of Irish convicts at Castle Hill in 1804. Soon however shortcomings in the corps convinced the War Office of the need for a more reliable garrison in New South Wales and Van Diemen's Land. Chief of these shortcomings was the Rum Rebellion, a coup mounted by its officers in 1808. As a result, in January 1810 the 73rd (Perthshire) Regiment of Foot arrived in Australia. By 1870, 25 British infantry regiments had served in Australia, as had a small number of artillery and engineer units.

MSU returned to the road to face Illinois at State Farm Center. Nick Ward did not start as Tom Izzo tried to send a message to his team. However, Illinois took an early lead and for the majority of the game as their intense defense forced the Spartans into 24 turnovers in the game. Cassius Winston alone had nine turnovers. However, the Spartans mounted a furious comeback late in the second half and even took the lead with just over six minutes left. However, Illinois went on a 15–8 run to end the game and notch the victory 79–74. MSU who had struggled from the free throw line against Indiana, made 23–25 against the Illini. The loss dropped MSU out of first place and put them a game behind Purdue and Michigan in the Big Ten standing with a 9–3 record, 18–5 overall.

Ocean Thermal Energy Corporation (OTE) currently has plans to install two 10 MW OTEC plants in the US Virgin Islands and a 5-10 MW OTEC facility in The Bahamas. OTE has also designed the world's largest Seawater Air Conditioning (SWAC) plant for a resort in The Bahamas, which will use cold deep seawater as a method of air-conditioning. In mid-2015, the 95%-complete project was temporarily put on hold while the resort resolved financial and ownership issues. On August 22, 2016, the government of the Bahamas announced that a new agreement had been signed under which the Baha Mar resort will be completed. On September 27, 2016, Bahamian Prime Minister Perry Christie announced that construction had resumed on Baha Mar, and that the resort was slated to open in March 2017.

Aside from its development, however, assessment in the health technology industry has been viewed as sporadic and fragmented Issues such as the determination of products that needed to be developed, cost, and access, among others, also emerged. These - some argue - need to be included in the assessment since health technology is never purely a matter of science but also of beliefs, values, and ideologies. One of the mechanisms being suggested – either as an element of- or an alternative to the current TAs is bioethics, which is also referred to as the "fourth-generation" evaluation framework. There are at least two dimensions to an ethical HTA. The first involves the incorporation of ethics in the methodological standards employed to assess technologies while the second is concerned with the use of ethical framework in research and judgment on the part of the researchers who produce information used in the industry.

In January 2013, as part of France's intervention in the Northern Mali conflict, a small number of Tigers were deployed for combat operations to that theatre. Early production HADs (Block 1) followed in November 2014 after having been declared combat capable. In March 2017, German Tigers were rotated into the same country in support of MINUSMA, relieving Apaches of the Royal Netherlands Air Force. On the 26th of July, one of the aircraft in question crashed in the desert 700 kilometres north of Gao, killing both pilots. A subsequent investigation discovered that mistakes by improperly trained civilian maintenance contractors had caused a fatal malfunction.

"Myxobolus cerebralis" is a myxosporean parasite of salmonids (salmon and trout species) that causes whirling disease in farmed salmon and trout and also in wild fish populations. It was first described in rainbow trout in Germany in 1893, but its range has spread and it has appeared in most of Europe (including Russia), the United States, South Africa, Canada and other countries due to the aid of humans of shipments of cultured and wild fish. In the 1980s, "M. cerebralis" was found to require a tubificid oligochaete (a kind of segmented worm) to complete its life cycle. The parasite infects its hosts with its cells after piercing them with polar filaments ejected from nematocyst-like capsules. This infects the cartilage and possibly the nervous tissue of salmonids, causing a potentially lethal infection. Causing the host to develop a black tail, spinal deformities, and possible more deformities in the anterior part of the fish.

The School continued its evening classes but now put a focus on its full-time day students, of whom six enrolled in the first term. On 5 February 1902 the foundation stone of new bakery buildings was laid by Thomas Fletcher of Birmingham Town Council, with John Humphry, president of the National Association of Master Bakers and Adam Lawson Johnston, chairman of the Committee present. On 9 September of that year, the School's new buildings were opened by Alderman Francis Tonsley JP, president of the National Association of Master Bakers, supported by the mayors of Northampton and Southwark, the chairman of the Institute and its governing body. Mr John Kirkland was appointed head of department in the same year. On 10 September 1909 the new day session of the National School for Bakers and Confectioners was opened by the Lord Mayor of London, Sir George Wyatt Truscott with 44 full-time students.

An increase in eosinophils, i.e., the presence of more than 500 eosinophils/microlitre of blood is called an eosinophilia, and is typically seen in people with a parasitic infestation of the intestines; autoimmune and collagen vascular disease (such as rheumatoid arthritis) and Systemic lupus erythematosus; malignant diseases such as eosinophilic leukemia, clonal hypereosinophilia, and Hodgkin lymphoma; lymphocyte-variant hypereosinophilia; extensive skin diseases (such as exfoliative dermatitis); Addison's disease and other causes of low corticosteroid production (corticosteroids suppress blood eosinophil levels); reflux esophagitis (in which eosinophils will be found in the squamous epithelium of the esophagus) and eosinophilic esophagitis; and with the use of certain drugs such as penicillin. But, perhaps the most common cause for eosinophilia is an allergic condition such as asthma. In 1989, contaminated L-tryptophan supplements caused a deadly form of eosinophilia known as eosinophilia-myalgia syndrome, which was reminiscent of the toxic oil syndrome in Spain in 1981.

The effectiveness of the TSP depends on a number of factors. Amongst the most critical are; the area of the titanium film, the temperature of the chamber walls and the composition of the residual gas. The area is typically maximised when considering where to mount the TSP. The reactivity of the new titanium film is increased at lower temperatures, so it is desirable to cool the relevant part of the chamber, typically using liquid nitrogen. However, due to the cost of the nitrogen and the need to ensure a continuous supply, TSPs are commonly operated at room temperature. Finally the residual gas composition is important - typically the pump works well with the more reactive components (such as CO and O), but is very ineffective at pumping inert components such as the noble gases and methane (CH). Therefore, TSP must be used in conjunction with other pumps.

Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. Use of all these techniques has enabled paleontologists to discover much of the evolutionary history of life, almost all the way back to when Earth became capable of supporting life, nearly 4 billion years ago. As knowledge has increased, paleontology has developed specialised sub-divisions, some of which focus on different types of fossil organisms while others study ecology and environmental history, such as ancient climates.

Bacon's public career ended in disgrace in 1621. After he fell into debt, a parliamentary committee on the administration of the law charged him with 23 separate counts of corruption. His lifelong enemy, Sir Edward Coke, who had instigated these accusations, was one of those appointed to prepare the charges against the chancellor. To the lords, who sent a committee to enquire whether a confession was really his, he replied, "My lords, it is my act, my hand, and my heart; I beseech your lordships to be merciful to a broken reed." He was sentenced to a fine of £40,000 and committed to the Tower of London at the king's pleasure; the imprisonment lasted only a few days and the fine was remitted by the king. More seriously, parliament declared Bacon incapable of holding future office or sitting in parliament. He narrowly escaped undergoing degradation, which would have stripped him of his titles of nobility. Subsequently, the disgraced viscount devoted himself to study and writing.

In Haskell and other functional programming languages, it is common to use a data type that is just as big as it needs to be to express any possible result. For example, we could write a division function that returned the type codice_13, and a codice_14 function returning codice_15. The first is an option type, which has only one failure value, codice_16. The second case is a tagged union: a result is either some string with a descriptive error message, or a successfully read character. Haskell's type inference system helps ensure that callers deal with possible errors. Since the error conditions become explicit in the function type, looking at its signature immediately tells the programmer how to treat errors. In addition, tagged unions and option types form monads when endowed with appropriate functions: this may be used to keep the code tidy by automatically propagating unhandled error conditions.

The 81st and other units, including the 168th Engineer Combat Battalion, pulled back from St. Vith on 21 December, under constant enemy fire, and withdrew over the Saint River at Vielsalm on 23 December. The following day, the 424th Regiment, attached to the 7th Armored Division, fought a delaying action at Manhay until ordered to an assembly area. From 25 December to 9 January 1945, the division received reinforcements and supplies at Anthisnes, Belgium, and returned to the struggle, securing objectives along the Ennal-Logbierme line on 15 January after heavy fighting. After being pinched out by advancing divisions, the 106th assembled at Stavelot on 18 January for rehabilitation and training. It moved to the vicinity of Hunningen on 7 February for defensive patrols and training.

In response to American and European pressure on Russia, a new revised agreement was reached in September 2006, under which fuel deliveries to Bushehr were scheduled to start in March 2007 and the plant was due to come on stream in September 2007 after years of delays. In February 2007, the work on the site faltered due to funding shortages, and Atomstroyexport reduced the number of employees working on the site from 3,000 to just 800. During subsequent negotiations, Atomstroyexport even contemplated pulling out of the project. In the end, an agreement was reached, under which the Iranians would compensate for the growing cost of equipment and engineering works once the reactor went live. A top Iranian nuclear official claimed that the Russians were deliberately delaying and politicising the project under European and American pressure.

The classic 1952 Miller–Urey experiment demonstrated that most amino acids, the chemical constituents of proteins, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth. External sources of energy may have triggered these reactions, including lightning, radiation, atmospheric entries of micro-meteorites and implosion of bubbles in sea and ocean waves. Other approaches ("metabolism-first" hypotheses) focus on understanding how catalysis in chemical systems on the early Earth might have provided the precursor molecules necessary for self-replication.

Confidence that the United States was catching up with the Soviet Union was shattered on April 12, 1961, when the Soviet Union launched Vostok 1, and cosmonaut Yuri Gagarin became the first man to orbit the Earth. In response, Kennedy announced a far more ambitious goal on May 25, 1961: to put a man on the Moon by the end of the decade. This already had a name: Project Apollo. Over the next few years, space science would constitute up to 20 percent of NASA's budget, but it would be dwarfed by spending on Project Apollo. NASA asked the Space Board to conduct a review of the space program, and this was done at the State University of Iowa between June 17 and July 31, 1962. The study recommended that scientists be included in the astronaut program, and that a scientist be included in the first mission to the Moon.

When the density of uniform tomographic view angles is under what is prescribed by the Nyquist-Shannon's sampling theorem, it is said that the imaging system is performing sparse sampling. Sparse sampling typically occurs as a way of keeping production costs low and improving image acquisition speed. The typical network architectures used to remove these sparse sampling artifacts are U-net and Fully Dense (FD) U-net. Both of these architectures contain a compression and decompression phase. The compression phase learns to compress the image to a latent representation that lacks the imaging artifacts and other details. The decompression phase then combines with information passed by the residual connections in order to add back image details without adding in the details associated with the artifacts. FD U-net modifies the original U-net architecture by including dense blocks that allow layers to utilize information learned by previous layers within the dense block. Another technique was proposed using a simple CNN based architecture for removal of artifacts and improving the k-wave image reconstruction.

This setup is preferred when core or crucial business activities are needed to be run at cheaper costs. The rationale for employing such a setup is to cater to long-term strategic plans involving high managerial control. In this case there are two major ways of setting up a captive market: these are the DIY or 'Start From Scratch' model and the Build-Operate-Transfer model. This way, the business practices and operations are still run within and by the firm, which mitigates risk of disclosure of sensitive information. In the Philippines there are examples of these setups, including American Express, JP Morgan, Wells Fargo and the currently-growing Capital One, which are all United States-based multinational companies.

Nilotinib has a number of adverse effects including headache, fatigue, gastrointestinal problems such as nausea, vomiting, diarrhea and constipation, muscle and joint pain, rash and other skin conditions, flu-like symptoms, and reduced blood cell count. Less typical side effects are those of the cardiovascular system, such as high blood pressure, various types of arrhythmia, and prolonged QT interval. Nilotinib can also affect the body's electrolyte and glucose balance. Though lung-related adverse effects are rare when compared with imatinib and dasatinib, there is a case report of acute respiratory failure from diffuse alveolar hemorrhage in a people taking nilotinib.

According to 2015 guidelines published by European resuscitation council, early initiation of resuscitation and coordination of lay people with medical personnel on helping an unconscious person is very helpful in increasing the chance of survival of the patient. When a person is unconscious and is not breathing normally, emergency services should be alerted and cardiopulmonary resuscitation (CPR) and mouth-to-mouth resuscitation (rescue breaths) should be initiated. High quality CPR is important. An adequate ratio of high quality chest compressions and rescue breaths are crucial. An automated external defibrillator (AED) machine is essential during resuscitation. Defibrillation during the first 3 to 5 minutes during resuscitation can produce survival rates as high as 50 to 70%. Placing AEDs in public places where there is one cardiac arrest in five years is cost-effective.

Before giving a mathematical proof for the formula for the volume of a sphere, Archimedes used physical reasoning to discover the solution (imagining the balancing of bodies on a scale). From the seventeenth century, many of the most important advances in mathematics appeared motivated by the study of physics, and this continued in the following centuries (although in the nineteenth century mathematics started to become increasingly independent from physics). The creation and development of calculus were strongly linked to the needs of physics: There was a need for a new mathematical language to deal with the new dynamics that had arisen from the work of scholars such as Galileo Galilei and Isaac Newton. During this period there was little distinction between physics and mathematics; as an example, Newton regarded geometry as a branch of mechanics. As time progressed, the mathematics used in physics has become increasingly sophisticated, as in the case of superstring theory.

In minor to moderate cases, nitroglycerine may be used to alleviate acute symptoms of stable angina or may be used immediately prior to exertion to prevent the onset of angina. Sublingual nitroglycerine is most commonly used to provide rapid relief for acute angina attacks and as a complement to anti-anginal treatments in patients with refractory and recurrent angina. When nitroglycerine enters the bloodstream, it forms free radical nitric oxide, or NO, which activates guanylate cyclase and in turn stimulates the release of cyclic GMP. This molecular signaling stimulates smooth muscle relaxation, ultimately resulting in vasodilation and consequently improved blood flow to regions of the heart affected by atherosclerotic plaque.

Camelids are large, strictly herbivorous animals with slender necks and long legs. They differ from ruminants in a number of ways. Their dentition show traces of vestigial central incisors in the incisive bone, and the third incisors have developed into canine-like tusks. Camelids also have true canine teeth and tusk-like premolars, which are separated from the molars by a gap. The musculature of the hind limbs differs from those of other ungulates in that the legs are attached to the body only at the top of the thigh, rather than attached by skin and muscle from the knee upwards. Because of this, camelids have to lie down by resting on their knees with their legs tucked underneath their bodies. They have three-chambered stomachs, rather than four-chambered ones; their upper lips are split in two, with each part separately mobile; and, uniquely among mammals, their red blood cells are elliptical. They also have a unique type of antibodies, which lack the light chain, in addition to the normal antibodies found in other mammals. These so-called heavy-chain antibodies are being used to develop single-domain antibodies with potential pharmaceutical applications.

Over the next 150 million years, these two parts moved towards each other, eventually uniting about 440 million years ago. Fossils discovered near Clogherhead, County Louth, show the coming together of shoreline fauna from both sides of the original dividing ocean. The mountains of northwest Ireland were formed during the collision, as was the granite that is found in locations in Donegal and Wicklow. The Irish landmass was now above sea level and lying near the equator, and fossil traces of land-based life forms survive from this period. These include fossilised trees from Kiltorcan, County Kilkenny, widespread bony fish and freshwater mussel fossils and the footprints of a four-footed amphibian preserved in slate on Valentia Island in Munster. Old Red Sandstone also formed at this time.

In common with other picornaviruses, the capsid of BEV is composed of 60 copies of each of four structural proteins, VP1, VP2, VP3 and VP4, in icosahedral symmetry, at about 27 nm in diameter, and enclosing a single stranded positive sense RNA genome of about 7,500 bases. The capsid is not enveloped and roughly spherical with an outer radius of 159 Ångströms and an inner radius of 107 Å. The outer surface of BEV is smoother than the closely related poliovirus due to the truncation of surface protein loops in BEV. It is also smoother than the related human rhinovirus due to the extension of a surface loop in BEV. The three antigenic sites of BEV all occur on a surface ridge at the junction between VP1, VP2, and VP3. BEV has a crater-like depression at the icosahedral 5-fold axis which descends into a cylindrical hole of 10 Å in diameter which runs almost to the inner surface of the capsid. A hydrophobic pocket contained within VP1 contains a myristic acid molecule, the removal of which appears to be a prerequisite for virus uncoating.

"Osmia xanthomelana" was known from around 28 scattered sites in Great Britain as far north as Tyneside but it was thought to have been reduced to a single site on the Isle of Wight by the 1990s, from which no bees have been recorded since the 1990s. However, two sites were discovered on the Llŷn Peninsula in Wales in 1998 and 1999. It is thought that individual sites can be lost due to erosion and sudden landslips and this is what destroyed the Isle of Wight site. The forage plant of "O. xanthomelana", bird's-foot trefoil, is sensitive to over or under grazing and these can result in the loss of the plants during the colony cycle of the bee. It is also thought that climate change and agricultural run-off from nearby intensive farmland are also threats to the bee populations. Conservation measures have included clearing invasive vegetation from banks and the creation of new banks.

Non-vertebrate fossils are more widely distributed in the Cedar Mountain Formation. These include the distinctive reproductive structures of fresh water algae that are called charophytes. Charophytes are so distinctive that they are used to correlate strata of similar age, and thus were used to show that the Yellow Cat Member was time equivalent to Barremian age strata in England. Ostracods, small crustaceans with clam-like shells, also occur in fresh water deposits, along with "finger-clams" or chonchostracans. Pollen have been found in the Mussentuchit Member and are important for reconstructing the environment. In a few places, large petrified logs are known, especially from the Poison Strip. These conifer logs are over a meter in diameter and indicate the presence of trees over 30 m (100 feet). The distinct wood of the tree fern "Tempskya" is occasional found as well.

His 1981 book "" was an exercise in futurology. O'Neill narrated it as a visitor to Earth from a space colony beyond Pluto. The book explored the effects of technologies he called "drivers of change" on the coming century. Some technologies he described were space colonies, solar power satellites, anti-aging drugs, hydrogen-propelled cars, climate control, and underground magnetic trains. He left the social structure of the 1980s intact, assuming that humanity would remain unchanged even as it expanded into the Solar System. Reviews of "2081" were mixed. "New York Times" reviewer John Noble Wilford found the book "imagination-stirring", but Charles Nicol thought the technologies described were unacceptably far-fetched.

The AMD FX line-up generally performed worse than its Intel competitors during its lifespan. The floating-point performance was relatively poor due to a single shared FPU per module. Most games also could not take advantage of the high core counts that the series provided. In applications that benefitted from more threads, AMD SKUs typically pulled ahead. This came at a great cost, however, as thermal efficiency was often worse than the previous generation of processors. Updates to the architecture that came with the Piledriver revision allowed for higher clock speeds. This led to better performance, but that came with the cost of even higher thermal output on the high end, which can be seen with the FX 9590, which outputs 220 Watts of heat.

Many practice the historical-grammatical method using the inductive method, a general three-fold approach to the text: observation, interpretation, and application. Each step builds upon the other, which follows in order. The first step of observation involves an examination of words, structure, structural relationships and literary forms. After observations are formed, then the second step of interpretation involves asking interpretative questions, formulating answers to those questions, integration and summarization of the passage. After the meaning is derived through interpretation, the third step of application involves determining both the theoretical and practical significance of the text and appropriately applying this significance to today's modern context. There is also a heavy emphasis on personal application that extends into all aspects of the practitioner's life. Theologian Robert Traina, in his 1952 "Methodical Bible Study", wrote that "the applicatory step is that for which all else exists. It represents the final purpose of Bible study."

Voice stress analysis (also called voice risk analysis) uses computers to compare pitch, frequency, intensity and micro tremors. In this way voice analysis "detect[s] minute variations in the voice thought to signal lying." It can even be used covertly over the phone, and has been used by banking and insurance companies as well as the government of the United Kingdom. Customers are assessed for truth in certain situations by banks and insurance companies where computers are used to record responses. Software then compares control questions to relevant questions assessed for deception. However, its reliability has been debated by peer-reviewed journals. "When a person lies, an involuntary interference of the nerves causes the vocal cords to produce a distorted sound wave, namely a frequency level which is different from the one produced by the same person when telling the truth."

Efforts to develop more environmentally friendly SIs have been made since the late 1990s and an increasing number of such SIs are becoming commercially available. Recent environmental awareness over the past 15 years has resulted in the production and application of more environmentally friendly SIs, otherwise called 'Green Scale Inhibitors' (GSI). These GSIs are designed to have reduced bio-accumulating and high biodegradability properties and therefore reduce pollution of the waters around oil production systems. Phosphate ester SIs, commonly employed for treating calcium carbonate scales are known to be environmentally friendly but poor inhibition efficiency. Release of SIs containing Nitrogen and Phosphorus distorts the natural equilibrium of the immediate water body with adverse effects on aquatic life.

As in other areas of chemistry, electron counting is useful for organizing organometallic chemistry. The 18-electron rule is helpful in predicting the stabilities of organometallic complexes, for example metal carbonyls and metal hydrides. The 18e rule has two representative electron counting models, ionic and neutral (also known as covalent) ligand models, respectively. The hapticity of a metal-ligand complex, can influence the electron count. Hapticity (η, lowercase Greek eta), describes the number of contiguous ligands coordinated to a metal. For example, ferrocene, [(η-CH)Fe], has two cyclopentadienyl ligands giving a hapticity of 5, where all five carbon atoms of the CH ligand bond equally and contribute one electron to the iron center. Ligands that bind non-contiguous atoms are denoted the Greek letter kappa, κ. Chelating κ2-acetate is an example. The covalent bond classification method identifies three classes of ligands, X,L, and Z; which are based on the electron donating interactions of the ligand. Many organometallic compounds do not follow the 18e rule. The metal atoms in organometallic compounds are frequently described by their d electron count and oxidation state. These concepts can be used to help predict their reactivity and preferred geometry. Chemical bonding and reactivity in organometallic compounds is often discussed from the perspective of the isolobal principle.

Born in Charlton, Massachusetts, William T. G. Morton was the son of James Morton, a miner, and Rebecca (Needham) Morton. William found work as a clerk, printer, and salesman in Boston before entering Baltimore College of Dental Surgery in 1840. In 1841, he gained notoriety for developing a new process to solder false teeth onto gold plates. In 1842, he left college after graduating to study in Hartford, Connecticut with dentist Horace Wells, with whom Morton shared a brief partnership. In 1843, Morton married Elizabeth Whitman of Farmington, Connecticut, the niece of former Congressman Lemuel Whitman. Her parents objected to Morton's profession and only agreed to the marriage after he promised to study medicine. In the autumn of 1844, Morton entered Harvard Medical School and attended the chemistry lectures of Charles T. Jackson, who introduced Morton to the anesthetic properties of ether. Morton then left Harvard without graduating.

This was the climate into which Boyd entered as interim institute president after Hansen had announced, on April 27, 1971, that he would be departing Georgia Tech to become president of Purdue University on July 1 of that year. Boyd stopped the plan for absolute absorption of the station, but did allow plans for closer control and more aggressive contract solicitation to proceed. Among these measures were increased resource-sharing, including increased sharing of physical assets and research staff. The latter was evidenced by the increase in joint faculty appointments between the EES and Georgia Tech. The move paid off, and the fiscal year 1970–1971 saw EES win new contracts and grants, totaling a record $5.2 million (equivalent to $ million in ).

A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range. In the mammalian peripheral nervous system, warmth receptors are thought to be unmyelinated C-fibres (low conduction velocity), while those responding to cold have both C-fibers and thinly myelinated A delta fibers (faster conduction velocity). The adequate stimulus for a warm receptor is warming, which results in an increase in their action potential discharge rate. Cooling results in a decrease in warm receptor discharge rate. For cold receptors their firing rate increases during cooling and decreases during warming. Some cold receptors also respond with a brief action potential discharge to high temperatures, i.e. typically above 45 °C, and this is known as a paradoxical response to heat. The mechanism responsible for this behavior has not been determined.

It is important to remember that permissive hypotension is a temporizing measure to improve outcomes until the source of bleeding is controlled. There are issues associated with prolonged permissive hypotension (> 90 min considered prolonged where detrimental effects outweigh benefits according to most recent animal studies - no human data available to date) that must be taken to account. Prolonged permissive hypotension can lead to aggravated post-injury coagulopathy (coagulation dysfunction), ischemic damage secondary to poor tissue perfusion including the brain, mitochondrial dysfunction, and lactic acidosis among others. It is also possible that other substances, such as estrogen (17 beta-estradiol) could allow for longer models of permissive hypotension. In a rat model of hemorrhagic shock, estrogen was able to reduce some of the negative effects of prolonged permissive hypotension as well as prolong long-term survival.

The biogeoclimatic zones of British Columbia are units of a classification system used by the British Columbia Ministry of Forests for the Canadian province's fourteen different broad, climatic ecosystems. The classification system, termed Biogeoclimatic Ecosystem Classification, exists independently of other ecoregion systems, one created by the World Wildlife Fund and the other in use by Environment Canada, which is based on one created by the Commission for Environmental Cooperation (CEC) and also in use by the US Environmental Protection Agency (EPA). The system of biogeoclimatic ecosystem classification was partly created for the purpose of managing forestry resources, but is also in use by the British Columbia Ministry of Environment and Climate Change Strategy and other provincial agencies. A biogeoclimatic zone is defined as "a geographic area having similar patterns of energy flow, vegetation and soils as a result of a broadly homogenous macroclimate."

Prior to the development of quantum mechanics as a separate theory, the mathematics used in physics consisted mainly of formal mathematical analysis, beginning with calculus, and increasing in complexity up to differential geometry and partial differential equations. Probability theory was used in statistical mechanics. Geometric intuition played a strong role in the first two and, accordingly, theories of relativity were formulated entirely in terms of differential geometric concepts. The phenomenology of quantum physics arose roughly between 1895 and 1915, and for the 10 to 15 years before the development of quantum mechanics (around 1925) physicists continued to think of quantum theory within the confines of what is now called classical physics, and in particular within the same mathematical structures. The most sophisticated example of this is the Sommerfeld–Wilson–Ishiwara quantization rule, which was formulated entirely on the classical phase space.

A total of 66 riders from 24 countries contested the difficult Greger Lewnhaupt-designed course, which no one was able to ride clear in the first round. Considered the first modern course in Olympic history, it was 775 meters in length, to be ridden at 400m/min, with 14 obstacles and 17 jumping efforts. The gold medal was awarded to Hans Günter Winkler of the Federal Republic of Germany, on his great mare Halla. He finished the first round with 4 faults, after landing heavily after an early takeoff by his mount, resulting in a pulled groin muscle. Knowing that withdrawal from the final round would result in his country's elimination, Winkler rode in the second round, and managed to complete it faultlessly. Winkler would go on to be one of the most medal-winning riders in Olympic history, with 7 medals to his name.

In January 2015, Algoma Central ordered three Equinox 740 self-unloaders from Croatian shipbuilder Uljanik, scheduled for delivery in 2018, though the schedule later slipped to late 2018 and early 2019. They are equipped with unloading booms mounted at the bow of the ship, in contrast to the conventional location at the aft end of the cargo holds, which gives operators added flexibility in unloading cargo. The majority of the ship's power systems are identical to the Chinese-built ships, though the main engine, while still an RT-flex50 model, is built by Winterthur Gas & Diesel. In October 2018, Algoma Central canceled the orders at Uljanik, citing severe delays in their construction as the shipyard faced major financial difficulties.

In 1929, two important laws concerning apartment buildings took effect. The law about "horizontal property" made it possible that many different owners own one apartment building, each by owning one or more apartment units. Theoretically, each apartment corresponds to a percentage of the original plot. The most important effect of this law was the practice of "αντιπαροχή" ("antiparochí", literally "a supply in exchange"). With "antiparochí", the owner of a plot, who can't afford to build an apartment building by himself, makes a contract with a construction company so that the latter will build the apartment building but keep the ownership of as many apartments as the contract states. Although during the inter-war period the practice of "antiparochí" was limited, as the construction of most apartment buildings was financed solely by the original owners of the plot, "antiparochí" became the most common method for financing the construction of condominiums (polykatoikíes) from the 1950s onwards. However this practice had the negative effect of the destruction of many old-era (mostly of 19th century) buildings and mansions in the major Greek cities, to be replaced by common apartment buildings. Even today (2019), the owners of old buildings or mansions, listed as architecturally preserved, prefer to let them collapse to avoid the preservation cost and exploit the plot.

It ran on an Apple II computer, and was considered a fourth generation software program. VisiCalc is widely credited for fueling the rapid growth of the personal computer industry. Instead of doing financial projections with manually calculated spreadsheets, and having to recalculate with every single cell in the sheet, VisiCalc allowed the user to change any cell, and have the entire sheet automatically recalculated. This could turn 20 hours of work into 15 minutes and allowed for more creativity.

A recently proposed early warning indicator of such population crashes uses effective estimation of the Lotka-Volterra interaction coefficients formula_27. The idea is that such coefficients can be obtained from spatial distributions of individuals of the different species through Maximum Entropy. This method was tested against the data collected for trees by the Barro Colorado Island Research Station, comprising eight censuses performed every 5 years from 1981 to 2015. The main finding was that for those tree species that suffered steep population declines (of at least 50 %), across the eight tree censuses, the drop of formula_37 is always steeper and occurs before the drop of the corresponding species abundance "N" .  Indeed, such sharp declines in formula_37 occur between 5 and 15 years in advance than comparable declines for "N", and thus they serve as early warnings of impending population busts.

"New poetry" introduced at the end of the 2nd century included that of Gaius Valerius Catullus, whose work include expressing desire for a freeborn youth explicitly named "Youth" ("Iuventius"). The Latin name and freeborn status of the beloved subvert Roman tradition. Catullus's contemporary Lucretius also recognizes the attraction of "boys" ("pueri", which can designate an acceptable submissive partner and not specifically age). Homoerotic themes occur throughout the works of poets writing during the reign of Augustus, including elegies by Tibullus and Propertius, several "Eclogues" of Vergil, especially the second, and some poems by Horace. In the "Aeneid," Vergil – who, according to a biography written by Suetonius, had a marked sexual preference for boys – draws on the Greek tradition of pederasty in a military setting by portraying the love between Nisus and Euryalus, whose military valor marks them as solidly Roman men ("viri"). Vergil describes their love as "pius", linking it to the supreme virtue of "pietas" as possessed by the hero Aeneas himself, and endorsing it as "honorable, dignified and connected to central Roman values".

Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size. Leaching can occur naturally seen from plant substances (inorganic and organic), solute leaching in soil, and in the decomposition of organic materials. Leaching can also be applied affectedly to enhance water quality and contaminant removal, as well as for disposal of hazardous waste products such as fly ash, or rare earth elements (REEs). Understanding leaching characteristics is important in preventing or encouraging the leaching process and preparing for it in the case where it is inevitable.

Above the critical temperature, "T", the Van der Waals equation is an improvement over the ideal gas law, and for lower temperatures, i.e., "T" < "T", the equation is also qualitatively reasonable for the liquid and low-pressure gaseous states; however, with respect to the first-order phase transition, i.e., the range of ("p, V, T") where a liquid phase and a gas phase would be in equilibrium, the equation appears to fail to predict observed experimental behaviour, in the sense that p is typically observed to be constant as a function of "V" for a given temperature in the two-phase region. This apparent discrepancy is resolved in the context of vapour–liquid equilibrium: at a particular temperature, there exist two points on the Van der Waals isotherm that have the same chemical potential, and thus a system in thermodynamic equilibrium will appear to traverse a straight line on the "p"–"V" diagram as the ratio of vapour to liquid changes. However, in such a system, there are really only two points present (the liquid and the vapour) rather than a series of states connected by a line, so connecting the locus of points is incorrect: it is not an equation of multiple states, but an equation of (a single) state. It is indeed possible to compress a gas beyond the point at which it would typically condense, given the right conditions, and it is also possible to expand a liquid beyond the point at which it would usually boil. Such states are called "metastable" states. Such behaviour is qualitatively (though perhaps not quantitatively) predicted by the Van der Waals equation of state.

Traditional occupational safety and health protection programs have primarily focused on ensuring that work is safe and that workers are protected from the harms that arise from work itself. TWH builds on this approach through the recognition that work is a social determinant of health. Job-related factors such as wages, hours of work, workload and stress levels, interactions with coworkers, and access to leave and healthful workplaces all can have an important impact on the well-being of workers, their families, and their communities. TWH explores opportunities to not only protect workers, but also "advance" their health and well-being by targeting the conditions of work. Scientific evidence now supports what many safety and health professionals, as well as workers themselves, have long suspected—that risk factors in the workplace can contribute to health problems previously considered unrelated to work. For example, there are work-related risk factors for abnormal weight fluctuations, sleep disorders, cardiovascular disease, depression, and other health conditions. In recognition of these emerging relationships, the TWH approach focuses on how environmental, workplace factors can both mitigate and enhance overall worker health beyond traditional occupational safety and health concerns.

An index is a copy of selected columns of data, from a table, that is designed to enable very efficient search. An index normally includes a "key" or direct link to the original row of data from which it was copied, to allow the complete row to be retrieved efficiently. Some databases extend the power of indexing by letting developers create indexes on column values that have been transformed by functions or expressions. For example, an index could be created on codice_1, which would only store the upper-case versions of the codice_2 field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Even with a fourth-place finish in their debut, Chrysler Corporation decided that the Le Mans project was no longer fruitful, and they canceled the entire program at the end of 2001. Chrysler's partner, Oreca, decided to continue on with the program as a privateer, replacing the Mopar V8 engines with Judd GV4 V10s. Although purchasing three SP1s, Oreca decided to use a two-car effort for Le Mans while the third car would be used in the FIA Sportscar Championship. In the first race of the season, the SP1 showed its potential by finishing second behind a Pescarolo Sport, then followed this up by gaining its first win at Autódromo do Estoril. For Le Mans, the SP1s continued to show the pace they had in 2001, taking the fourth-fastest qualifying time behind the trio of R8s. In the race itself, both SP1s performed well, remaining immediately behind the leading R8s and Bentley for the entire race, finishing in fifth and sixth place overall, both cars 16 laps behind the winner. Oreca would not continue with the SP1s, deciding to take a brief hiatus from prototypes to work on other projects.

The study of MOFs has roots in coordination chemistry and solid-state inorganic chemistry, but it developed to form a new field. In addition, MOFs are constructed from bridging organic ligands that remain intact throughout the synthesis. Zeolite synthesis often makes use of a "template". Templates are ions that influence the structure of the growing inorganic framework. Typical templating ions are quaternary ammonium cations, which are removed later. In MOFs, the framework is templated by the SBU (secondary building unit) and the organic ligands. A templating approach that is useful for MOFs intended for gas storage is the use of metal-binding solvents such as N,N-diethylformamide and water. In these cases, metal sites are exposed when the solvent is evacuated, allowing hydrogen to bind at these sites.

In 2014, Operation Car Wash, an investigation by the Federal Police of Brazil, uncovered unprecedented money laundering and corruption at the state-controlled oil company Petrobras. In early 2015, a series of protests against alleged corruption by the government of President Dilma Rousseff began in Brazil, triggered by revelations that numerous politicians were involved in the Petrobras affair. By early 2016, the scandal had escalated into a full-blown political crisis affecting not only President Rousseff, but also former President Luiz Inácio Lula da Silva, resulting in widespread demonstrations involving millions of protesters, both anti- and pro-Rousseff. At the same time, Brazil faced its worst economic recession since the 1990s, raising questions about whether the country was adequately prepared to host the Olympic Games against a volatile political and economic backdrop. On 12 May 2016, President Rousseff was stripped of her powers and duties for 180 days after an impeachment vote in the Federal Senate, with Vice President Michel Temer standing in as acting president during the Games.

Three ideas developed that enabled the reconstruction of real space images from diffraction patterns. The first idea was the realization by Sayre in 1952 that Bragg diffraction under-samples diffracted intensity relative to Shannon's theorem. If the diffraction pattern is sampled at twice the Nyquist frequency (inverse of sample size) or denser it can yield a unique real space image. The second was an increase in computing power in the 1980s which enabled iterative hybrid input output (HIO) algorithm for phase retrieval to optimize and extract phase information using adequately sampled intensity data with feedback. This method was introduced by Fienup in the 1980s. Finally, the development of "phase recovery" algorithms led to the first demonstration of CDI in 1999 by Miao

In troughs, the structure's topography can accelerate flows and form jets that result in maximum erosion along the deflation basin floor and laterally expand the slopes of the blowout. Additionally, when the wind flows on top of the blowout's lateral walls, sediment transport is at its maximum in the middle axis of the trough depositional lobe, leading to formation of a parabolic dune. Although some studies like Hesp and Pringle (2001) noted that wind flow that was oblique to the blowouts’ orientation became pulled into the depression due to a zone of low pressure at the deflation basin and was steered parallel to the orientation of the trough blowout. However, in Smyth, Jackson, and Cooper’s study (2014), little evidence supported that wind flow was being steered along the axis of the blowout, but rather the flow remained constant in the direction that it was flowing before or showed other characteristics like turbulent separated flows.

Upon encountering a Chi site, the activity of the RecBCD enzyme changes drastically. DNA unwinding pauses for a few seconds and then resumes at roughly half the initial speed. This is likely because the slower RecB helicase unwinds the DNA after Chi, rather than the faster RecD helicase, which unwinds the DNA before Chi. Recognition of the Chi site also changes the RecBCD enzyme so that it cuts the DNA strand with Chi and begins loading multiple RecA proteins onto the single-stranded DNA with the newly generated 3' end. The resulting RecA-coated nucleoprotein filament then searches out similar sequences of DNA on a homologous chromosome. The search process induces stretching of the DNA duplex, which enhances homology recognition (a mechanism termed conformational proofreading). Upon finding such a sequence, the single-stranded nucleoprotein filament moves into the homologous recipient DNA duplex in a process called "strand invasion". The invading 3' overhang causes one of the strands of the recipient DNA duplex to be displaced, to form a D-loop. If the D-loop is cut, another swapping of strands forms a cross-shaped structure called a Holliday junction. Resolution of the Holliday junction by some combination of RuvABC or RecG can produce two recombinant DNA molecules with reciprocal genetic types, if the two interacting DNA molecules differ genetically. Alternatively, the invading 3’ end near Chi can prime DNA synthesis and form a replication fork. This type of resolution produces only one type of recombinant (non-reciprocal).

The equipartition theorem makes quantitative predictions. Like the virial theorem, it gives the total average kinetic and potential energies for a system at a given temperature, from which the system's heat capacity can be computed. However, equipartition also gives the average values of individual components of the energy, such as the kinetic energy of a particular particle or the potential energy of a single spring. For example, it predicts that every atom in a monatomic ideal gas has an average kinetic energy of in thermal equilibrium, where is the Boltzmann constant and "T" is the (thermodynamic) temperature. More generally, equipartition can be applied to any classical system in thermal equilibrium, no matter how complicated. It can be used to derive the ideal gas law, and the Dulong–Petit law for the specific heat capacities of solids. The equipartition theorem can also be used to predict the properties of stars, even white dwarfs and neutron stars, since it holds even when relativistic effects are considered.

On February 19, 1426, Masaccio was commissioned by Giuliano di Colino degli Scarsi da San Giusto, for the sum of 80 florins, to paint a major altarpiece, the "Pisa Altarpiece", for his chapel in the church of Santa Maria del Carmine in Pisa. The work was dismantled and dispersed in the 18th century, and only eleven of about twenty original panels have been rediscovered in various collections around the world. The central panel of the altarpiece ("The Madonna and Child") is now in the National Gallery, London. Although it is very damaged, the work features a sculptural and human Madonna as well as a convincing perspectival depiction of her throne. Masaccio probably worked on it entirely in Pisa, shuttling back and forth to Florence, where he was still working on the Brancacci Chapel. In these years, Donatello was also working in Pisa at a monument for Cardinal Rinaldo Brancacci, to be sent to Naples. It is suggested that Masaccio's first ventures in plasticity and perspective were based on Donatello's sculpture, before he could study Brunelleschi's more scientific approach to perspective.

The M1 Garand was made in large numbers during World War II; approximately 5.4 million were made. They were used by every branch of the United States military. The rifle generally performed well. General George S. Patton called it "the greatest battle implement ever devised." The typical opponent of a US soldier during World War II was usually armed with a slower-firing bolt-action rifle (e.g. the Karabiner 98k for Germany and the Arisaka rifle for Japan). The impact of faster-firing infantry small arms in general soon stimulated both Allied and Axis forces to greatly increase their issue of semi- and fully automatic firearms then in production, as well as to develop new types of infantry firearms.

Marine evidence indicates that the area initially opened to form an ocean called the Manikewan Ocean. Faulting, sedimentary and igneous rocks all indicate that divergence formed a rift valley that continued to spread until it resulted in a passive margin in which there was no tectonic activity. Shallow marine deposits formed on the continental shelves, and oceanic crust formed on the margins of the continental cratons as the divergence continued. Eventually the divergence stopped, then reversed direction, and collision occurred between continental land masses. During the Wopmay orogeny, subduction occurred as oceanic crust of the Slave Craton was subducted beneath an eastward moving continental plate. Likewise, during the Trans-Hudson orogeny, rifting at first separated the Superior craton from the rest of the continent. Then the Superior Craton reversed its direction and the ocean basin began to close. A subduction zone formed as the oceanic crust of the Superior Craton was subducted beneath the Hearne and Wyoming Craton with the Sask Craton in the middle. Volcanic arcs developed as the cratons collided, eventually resulting in the THO mountain building (orogeny).
