According to Tony Sclafani from MSNBC, "It's worth noting that before Madonna, most music mega-stars were guy rockers; after her, almost all would be female singers ... When The Beatles hit America, they changed the paradigm of performer from solo act to band. Madonna changed it back—with an emphasis on the female." Howard Kramer, curatorial director of the Rock and Roll Hall of Fame and Museum, asserted that "Madonna and the career she carved out for herself made possible virtually every other female pop singer to follow ... She certainly raised the standards of all of them ... She redefined what the parameters were for female performers." According to Fouz-Hernández, subsequent female singers such as Britney Spears, Christina Aguilera, Kylie Minogue, the Spice Girls, Destiny's Child, Jennifer Lopez, and Pink were like her "daughters in the very direct sense that they grew up listening to and admiring Madonna, and decided they wanted to be like her." Time magazine included her in the list of the "25 Most Powerful Women of the Past Century", where she became one of only two singers to be included, alongside Aretha Franklin. She also topped VH1's lists of "100 Greatest Women in Music" and "50 Greatest Women of the Video Era".

New York has been described as the "Capital of Baseball". There have been 35 Major League Baseball World Series and 73 pennants won by New York teams. It is one of only five metro areas (Los Angeles, Chicago, Baltimore–Washington, and the San Francisco Bay Area being the others) to have two baseball teams. Additionally, there have been 14 World Series in which two New York City teams played each other, known as a Subway Series and occurring most recently in 2000. No other metropolitan area has had this happen more than once (Chicago in 1906, St. Louis in 1944, and the San Francisco Bay Area in 1989). The city's two current Major League Baseball teams are the New York Mets, who play at Citi Field in Queens, and the New York Yankees, who play at Yankee Stadium in the Bronx. who compete in six games of interleague play every regular season that has also come to be called the Subway Series. The Yankees have won a record 27 championships, while the Mets have won the World Series twice. The city also was once home to the Brooklyn Dodgers (now the Los Angeles Dodgers), who won the World Series once, and the New York Giants (now the San Francisco Giants), who won the World Series five times. Both teams moved to California in 1958. There are also two Minor League Baseball teams in the city, the Brooklyn Cyclones and Staten Island Yankees.

Some organisms, such as the lichen Trapelia involuta or microorganisms such as the bacterium Citrobacter, can absorb concentrations of uranium that are up to 300 times the level of their environment. Citrobacter species absorb uranyl ions when given glycerol phosphate (or other similar organic phosphates). After one day, one gram of bacteria can encrust themselves with nine grams of uranyl phosphate crystals; this creates the possibility that these organisms could be used in bioremediation to decontaminate uranium-polluted water. The proteobacterium Geobacter has also been shown to bioremediate uranium in ground water. The mycorrhizal fungus Glomus intraradices increases uranium content in the roots of its symbiotic plant.

Question: What microorganism can notably absorb a very high concentrate of uranium?
Answer: Citrobacter.

In 1853, Victoria gave birth to her eighth child, Leopold, with the aid of the new anaesthetic, chloroform. Victoria was so impressed by the relief it gave from the pain of childbirth that she used it again in 1857 at the birth of her ninth and final child, Beatrice, despite opposition from members of the clergy, who considered it against biblical teaching, and members of the medical profession, who thought it dangerous. Victoria may have suffered from post-natal depression after many of her pregnancies. Letters from Albert to Victoria intermittently complain of her loss of self-control. For example, about a month after Leopold's birth Albert complained in a letter to Victoria about her "continuance of hysterics" over a "miserable trifle".

Since the armature windings of a direct-current or universal motor are moving through a magnetic field, they have a voltage induced in them. This voltage tends to oppose the motor supply voltage and so is called "back electromotive force (emf)". The voltage is proportional to the running speed of the motor. The back emf of the motor, plus the voltage drop across the winding internal resistance and brushes, must equal the voltage at the brushes. This provides the fundamental mechanism of speed regulation in a DC motor. If the mechanical load increases, the motor slows down; a lower back emf results, and more current is drawn from the supply. This increased current provides the additional torque to balance the new load.

Question: Voltage at the brushes is equal to what?
Answer: back emf of the motor, plus the voltage drop across the winding internal resistance.

In the late 1800s, Presbyterian missionaries established a presence in what is now northern New Mexico. This provided an alternative to the Catholicism, which was brought to the area by the Spanish Conquistadors and had remained unchanged. The area experienced a "mini" reformation, in that many converts were made to Presbyterianism, prompting persecution. In some cases, the converts left towns and villages to establish their own neighboring villages. The arrival of the United States to the area prompted the Catholic church to modernize and make efforts at winning the converts back, many of which did return. However, there are still stalwart Presbyterians and Presbyterian churches in the area.

Memories and lessons from the war are still a major factor in American politics. One side views the war as a necessary part of the Containment policy, which allowed the enemy to choose the time and place of warfare. Others note the U.S. made major strategic gains as the Communists were defeated in Indonesia, and by 1972 both Moscow and Beijing were competing for American support, at the expense of their allies in Hanoi. Critics see the conflict as a "quagmire"—an endless waste of American blood and treasure in a conflict that did not concern US interests. Fears of another quagmire have been major factors in foreign policy debates ever since. The draft became extremely unpopular, and President Nixon ended it in 1973, forcing the military (the Army especially) to rely entirely upon volunteers. That raised the issue of how well the professional military reflected overall American society and values; the soldiers typically took the position that their service represented the highest and best American values.

In the aftermath of the failed coup, militias loyal to Patassé sought revenge against rebels in many neighborhoods of Bangui and incited unrest including the murder of many political opponents. Eventually, Patassé came to suspect that General François Bozizé was involved in another coup attempt against him, which led Bozizé to flee with loyal troops to Chad. In March 2003, Bozizé launched a surprise attack against Patassé, who was out of the country. Libyan troops and some 1,000 soldiers of Bemba's Congolese rebel organization failed to stop the rebels and Bozizé's forces succeeded in overthrowing Patassé.[citation needed]

The important legacy of this period included substantial advances in factual knowledge, especially in anatomy, zoology, botany, mineralogy, geography, mathematics and astronomy; an awareness of the importance of certain scientific problems, especially those related to the problem of change and its causes; and a recognition of the methodological importance of applying mathematics to natural phenomena and of undertaking empirical research. In the Hellenistic age scholars frequently employed the principles developed in earlier Greek thought: the application of mathematics and deliberate empirical research, in their scientific investigations. Thus, clear unbroken lines of influence lead from ancient Greek and Hellenistic philosophers, to medieval Muslim philosophers and scientists, to the European Renaissance and Enlightenment, to the secular sciences of the modern day. Neither reason nor inquiry began with the Ancient Greeks, but the Socratic method did, along with the idea of Forms, great advances in geometry, logic, and the natural sciences. According to Benjamin Farrington, former Professor of Classics at Swansea University:

The decline in the value of the U.S. dollar corresponds to price inflation, which is a rise in the general level of prices of goods and services in an economy over a period of time. A consumer price index (CPI) is a measure estimating the average price of consumer goods and services purchased by households. The United States Consumer Price Index, published by the Bureau of Labor Statistics, is a measure estimating the average price of consumer goods and services in the United States. It reflects inflation as experienced by consumers in their day-to-day living expenses. A graph showing the U.S. CPI relative to 1982–1984 and the annual year-over-year change in CPI is shown at right.

In his usurpation of the throne from the Jianwen Emperor (r. 1398–1402), the Yongle Emperor was aided by the Buddhist monk Yao Guangxiao, and like his father, the Hongwu Emperor, the Yongle Emperor was "well-disposed towards Buddhism", claims Rossabi. On March 10, 1403, the Yongle Emperor invited Deshin Shekpa, 5th Karmapa Lama (1384–1415), to his court, even though the fourth Karmapa had rejected the invitation of the Hongwu Emperor. A Tibetan translation in the 16th century preserves the letter of the Yongle Emperor, which the Association for Asian Studies notes is polite and complimentary towards the Karmapa. The letter of invitation reads,

Hastings was entrusted with the power of peace and war. British judges and magistrates would also be sent to India to administer the legal system. The Governor General and the council would have complete legislative powers. The company was allowed to maintain its virtual monopoly over trade in exchange for the biennial sum and was obligated to export a minimum quantity of goods yearly to Britain. The costs of administration were to be met by the company. The Company initially welcomed these provisions, but the annual burden of the payment contributed to the steady decline of its finances.

Many birds show plumage patterns in ultraviolet that are invisible to the human eye; some birds whose sexes appear similar to the naked eye are distinguished by the presence of ultraviolet reflective patches on their feathers. Male blue tits have an ultraviolet reflective crown patch which is displayed in courtship by posturing and raising of their nape feathers. Ultraviolet light is also used in foraging—kestrels have been shown to search for prey by detecting the UV reflective urine trail marks left on the ground by rodents. The eyelids of a bird are not used in blinking. Instead the eye is lubricated by the nictitating membrane, a third eyelid that moves horizontally. The nictitating membrane also covers the eye and acts as a contact lens in many aquatic birds. The bird retina has a fan shaped blood supply system called the pecten. Most birds cannot move their eyes, although there are exceptions, such as the great cormorant. Birds with eyes on the sides of their heads have a wide visual field, while birds with eyes on the front of their heads, such as owls, have binocular vision and can estimate the depth of field. The avian ear lacks external pinnae but is covered by feathers, although in some birds, such as the Asio, Bubo and Otus owls, these feathers form tufts which resemble ears. The inner ear has a cochlea, but it is not spiral as in mammals.

The Spanish ship San Pedro and two other vessels in an expedition commanded by Miguel López de Legazpi discovered an island on January 9, 1530, possibly Mejit, at 10°N, which they named "Los Barbudos". The Spaniards went ashore and traded with the local inhabitants. On January 10, the Spaniards sighted another island that they named "Placeres", perhaps Ailuk; ten leagues away, they sighted another island that they called "Pajares" (perhaps Jemo). On January 12, they sighted another island at 10°N that they called "Corrales" (possibly Wotho). On January 15, the Spaniards sighted another low island, perhaps Ujelang, at 10°N, where they described the people on "Barbudos". After that, ships including the San Jeronimo, Los Reyes and Todos los Santos also visited the islands in different years.

In the 1980s, parents of mixed-race children began to organize and lobby for the addition of a more inclusive term of racial designation that would reflect the heritage of their children. When the U.S. government proposed the addition of the category of "bi-racial" or "multiracial" in 1988, the response from the public was mostly negative. Some African-American organizations, and African-American political leaders, such as Congresswoman Diane Watson and Congressman Augustus Hawkins, were particularly vocal in their rejection of the category, as they feared the loss of political and economic power if African Americans reduced their numbers by self-identification.

Oklahoma is part of a geographical region characterized by conservative and Evangelical Christianity known as the "Bible Belt". Spanning the southern and eastern parts of the United States, the area is known for politically and socially conservative views, even though Oklahoma has more voters registered with the Democratic Party than with any other party. Tulsa, the state's second largest city, home to Oral Roberts University, is sometimes called the "buckle of the Bible Belt". According to the Pew Research Center, the majority of Oklahoma's religious adherents – 85 percent – are Christian, accounting for about 80 percent of the population. The percentage of Oklahomans affiliated with Catholicism is half of the national average, while the percentage affiliated with Evangelical Protestantism is more than twice the national average – tied with Arkansas for the largest percentage of any state.

The quarter-wave elements imitate a series-resonant electrical element due to the standing wave present along the conductor. At the resonant frequency, the standing wave has a current peak and voltage node (minimum) at the feed. In electrical terms, this means the element has minimum reactance, generating the maximum current for minimum voltage. This is the ideal situation, because it produces the maximum output for the minimum input, producing the highest possible efficiency. Contrary to an ideal (lossless) series-resonant circuit, a finite resistance remains (corresponding to the relatively small voltage at the feed-point) due to the antenna's radiation resistance as well as any actual electrical losses.

Question: How would you describe a current that has maximum efficiency?
Answer: minimum reactance.

The macronutrients are carbohydrates, fats, protein, and water. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in Joules or kilocalories (often called "Calories" and written with a capital C to distinguish them from little 'c' calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram, though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons.

Question: What other significant aspect do macronutrients provide other than energy?
Answer: structural material.
