Prevention of infectious diarrhea is by improved sanitation, clean drinking water, and hand washing with soap. Breastfeeding for at least six months is also recommended as is vaccination against rotavirus. Oral rehydration solution (ORS), which is clean water with modest amounts of salts and sugar, is the treatment of choice. Zinc tablets are also recommended. These treatments have been estimated to have saved 50 million children in the past 25 years. When people have diarrhea it is recommended that they continue to eat healthy food and babies continue to be breastfed. If commercial ORS are not available, homemade solutions may be used. In those with severe dehydration, intravenous fluids may be required. Most cases; however, can be managed well with fluids by mouth. Antibiotics, while rarely used, may be recommended in a few cases such as those who have bloody diarrhea and a high fever, those with severe diarrhea following travelling, and those who grow specific bacteria or parasites in their stool. Loperamide may help decrease the number of bowel movement but is not recommended in those with severe disease.

During colonial times, Edenton served as the state capital beginning in 1722, and New Bern was selected as the capital in 1766. Construction of Tryon Palace, which served as the residence and offices of the provincial governor William Tryon, began in 1767 and was completed in 1771. In 1788 Raleigh was chosen as the site of the new capital, as its central location protected it from attacks from the coast. Officially established in 1792 as both county seat and state capital, the city was named after Sir Walter Raleigh, sponsor of Roanoke, the "lost colony" on Roanoke Island.

In 1968 Ronald Melzack and Kenneth Casey described pain in terms of its three dimensions: "sensory-discriminative" (sense of the intensity, location, quality and duration of the pain), "affective-motivational" (unpleasantness and urge to escape the unpleasantness), and "cognitive-evaluative" (cognitions such as appraisal, cultural values, distraction and hypnotic suggestion). They theorized that pain intensity (the sensory discriminative dimension) and unpleasantness (the affective-motivational dimension) are not simply determined by the magnitude of the painful stimulus, but "higher" cognitive activities can influence perceived intensity and unpleasantness. Cognitive activities "may affect both sensory and affective experience or they may modify primarily the affective-motivational dimension. Thus, excitement in games or war appears to block both dimensions of pain, while suggestion and placebos may modulate the affective-motivational dimension and leave the sensory-discriminative dimension relatively undisturbed." (p. 432) The paper ends with a call to action: "Pain can be treated not only by trying to cut down the sensory input by anesthetic block, surgical intervention and the like, but also by influencing the motivational-affective and cognitive factors as well." (p. 435)

Question: What did Melzack and Casey theorize could influence the perception of the magnitude of pain?
Answer: cognitive activities.

Both the archipelagos of the Azores and Madeira have a subtropical climate, although variations between islands exist, making weather predictions very difficult (owing to rough topography). The Madeira and Azorean archipelagos have a narrower temperature range, with annual average temperatures exceeding 20 °C (68 °F) along the coast (according to the Portuguese Meteorological Institute). Some islands in Azores do have drier months in the summer. Consequently, the island of the Azores have been identified as having a Mediterranean climate (both Csa and Csb types), while some islands (such as Flores or Corvo) are classified as Maritime Temperate (Cfb) and Humid subtropical (Cfa), respectively, according to Köppen-Geiger classification.

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to a high temperature, by passing an electric current through it, until it glows with visible light (incandescence). The hot filament is protected from oxidation with a glass or quartz bulb that is filled with inert gas or evacuated. In a halogen lamp, filament evaporation is prevented by a chemical process that redeposits metal vapor onto the filament, extending its life. The light bulb is supplied with electric current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket which provides mechanical support and electrical connections.

Question: What type of energy makes an incandescent light bulb glow?
Answer: electric current.

A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning), grapes and raisins, macadamia nuts, xylitol, as well as various plants and other potentially ingested materials. The nicotine in tobacco can also be dangerous. Dogs can get it by scavenging in garbage or ashtrays; eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea. Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are highly susceptible to theobromine poisoning, typically from ingestion of chocolate. Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that even small amounts of chocolate can be fatal, especially dark chocolate.

Boston has a continental climate with some maritime influence, and using the −3 °C (27 °F) coldest month (January) isotherm, the city lies within the transition zone from a humid subtropical climate (Köppen Cfa) to a humid continental climate (Köppen Dfa), although the suburbs north and west of the city are significantly colder in winter and solidly fall under the latter categorization; the city lies at the transition between USDA plant hardiness zones 6b (most of the city) and 7a (Downtown, South Boston, and East Boston neighborhoods). Summers are typically warm to hot, rainy, and humid, while winters oscillate between periods of cold rain and snow, with cold temperatures. Spring and fall are usually mild, with varying conditions dependent on wind direction and jet stream positioning. Prevailing wind patterns that blow offshore minimize the influence of the Atlantic Ocean. The hottest month is July, with a mean temperature of 73.4 °F (23.0 °C). The coldest month is January, with a mean of 29.0 °F (−1.7 °C). Periods exceeding 90 °F (32 °C) in summer and below freezing in winter are not uncommon but rarely extended, with about 13 and 25 days per year seeing each, respectively. The most recent sub-0 °F (−18 °C) reading occurring on February 14, 2016 when the temperature dipped down to −9 °F (−23 °C), the coldest reading since 1957. In addition, several decades may pass between 100 °F (38 °C) readings, with the most recent such occurrence on July 22, 2011 when the temperature reached 103 °F (39 °C). The city's average window for freezing temperatures is November 9 through April 5.[c] Official temperature records have ranged from −18 °F (−28 °C) on February 9, 1934, up to 104 °F (40 °C) on July 4, 1911; the record cold daily maximum is 2 °F (−17 °C) on December 30, 1917, while, conversely, the record warm daily minimum is 83 °F (28 °C) on August 2, 1975.

Subtractive methods remove copper from an entirely copper-coated board to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process. The advantage of the additive method is that less material is needed and less waste is produced. In the full additive process the bare laminate is covered with a photosensitive film which is imaged (exposed to light through a mask and then developed which removes the unexposed film). The exposed areas are sensitized in a chemical bath, usually containing palladium and similar to that used for through hole plating which makes the exposed area capable of bonding metal ions. The laminate is then plated with copper in the sensitized areas. When the mask is stripped, the PCB is finished.

In consequence to the Reform War, the federal government was bankrupt and could not pay its foreign debts to Spain, England, and France. On July 17, 1861, President Juárez decreed a moratorium on payment to foreign debtors for a period of two years. Spain, England, and France did not accept the moratorium by Mexico; they united at the Convention of the Triple Alliance on October 31, 1861 in which they agreed to take possession of several custom stations within Mexico as payment. A delegation of the Triple Alliance arrived in Veracruz in December 1861. President Juárez immediately sent his Foreign Affairs Minister, Manuel Doblado, who is able to reduce the debts through the Pacto de Soledad (Soledad Pact). General Juan Prim of Spain persuaded the English delegation to accept the terms of the Pacto de Soledad, but the French delegation refused.

As the summit closed on 28 September 1970, hours after escorting the last Arab leader to leave, Nasser suffered a heart attack. He was immediately transported to his house, where his physicians tended to him. Nasser died several hours later, around 6:00 p.m. Heikal, Sadat, and Nasser's wife Tahia were at his deathbed. According to his doctor, al-Sawi Habibi, Nasser's likely cause of death was arteriosclerosis, varicose veins, and complications from long-standing diabetes. Nasser was a heavy smoker with a family history of heart disease—two of his brothers died in their fifties from the same condition. The state of Nasser's health was not known to the public prior to his death. He had previously suffered heart attacks in 1966 and September 1969.

This age saw the Greeks move towards larger cities and a reduction in the importance of the city-state. These larger cities were parts of the still larger Kingdoms of the Diadochi. Greeks, however, remained aware of their past, chiefly through the study of the works of Homer and the classical authors. An important factor in maintaining Greek identity was contact with barbarian (non-Greek) peoples, which was deepened in the new cosmopolitan environment of the multi-ethnic Hellenistic kingdoms. This led to a strong desire among Greeks to organize the transmission of the Hellenic paideia to the next generation. Greek science, technology and mathematics are generally considered to have reached their peak during the Hellenistic period.

But for an element  which is short circuited, a current is generated across that short but no voltage is allowed, so the corresponding . This is the case, for instance, with the so-called parasitic elements of a Yagi-Uda antenna where the solid rod can be viewed as a dipole antenna shorted across its feedpoint. Parasitic elements are unpowered elements that absorb and reradiate RF energy according to the induced current calculated using such a system of equations.

The majority of video compression algorithms use lossy compression. Uncompressed video requires a very high data rate. Although lossless video compression codecs perform at a compression factor of 5-12, a typical MPEG-4 lossy compression video has a compression factor between 20 and 200. As in all lossy compression, there is a trade-off between video quality, cost of processing the compression and decompression, and system requirements. Highly compressed video may present visible or distracting artifacts.

Many sleeping birds bend their heads over their backs and tuck their bills in their back feathers, although others place their beaks among their breast feathers. Many birds rest on one leg, while some may pull up their legs into their feathers, especially in cold weather. Perching birds have a tendon locking mechanism that helps them hold on to the perch when they are asleep. Many ground birds, such as quails and pheasants, roost in trees. A few parrots of the genus Loriculus roost hanging upside down. Some hummingbirds go into a nightly state of torpor accompanied with a reduction of their metabolic rates. This physiological adaptation shows in nearly a hundred other species, including owlet-nightjars, nightjars, and woodswallows. One species, the common poorwill, even enters a state of hibernation. Birds do not have sweat glands, but they may cool themselves by moving to shade, standing in water, panting, increasing their surface area, fluttering their throat or by using special behaviours like urohidrosis to cool themselves.

Question: These types of birds have a tendon locking mechanism.
Answer: Perching birds.

ARC was acquired in 1938 by the Columbia Broadcasting System (CBS, which, in turn, had been formed by the Columbia Phonograph Company, but then sold off). ARC was renamed Columbia Recording Corporation. The Columbia Phonograph Company had international subsidiaries and affiliates such as the Columbia Graphophone Company in the United Kingdom, but they were sold off prior to CBS acquiring American Columbia. RCA Victor Records executive Ted Wallerstein convinced CBS head William S. Paley to buy ARC and Paley made Wallerstein head of the newly acquired record company. The renamed company made Columbia its flagship label with Okeh its subsidiary label while deemphasizing ARC's other labels. This allowed ARC's leased labels Brunswick Records and Vocalion Records to revert to former owner Warner Bros. which sold the labels to Decca Records. Columbia kept the Brunswick catalogue recorded from December 1931 onward which was reissued on the Columbia label as well as the Vocalion label material from the same time period which was reissued on the Okeh label. Wallerstein, who was promoted at the end of 1947 from president to chairman of the record company, restored Columbia's status as a leading record company and spearheaded the successful introduction of the long playing (LP) record before he retired as Columbia's chairman in 1951. James Conkling then became head of Columbia Records. Also in 1951, Columbia severed its ties with the EMI-owned record label of the same name and began a UK distribution deal with Philips Records, whereas Okeh Records continued to be distributed by EMI on the Columbia label.
