The Vedic period is named after the Indo-Aryan culture of north-west India, although other parts of India had a distinct cultural identity during this period. The Vedic culture is described in the texts of Vedas, still sacred to Hindus, which were orally composed in Vedic Sanskrit. The Vedas are some of the oldest extant texts in India. The Vedic period, lasting from about 1750 to 500 BCE, and contributed the foundations of several cultural aspects of Indian subcontinent. In terms of culture, many regions of the subcontinent transitioned from the Chalcolithic to the Iron Age in this period.

The foundation trust invests undistributed assets, with the exclusive goal of maximizing the return on investment. As a result, its investments include companies that have been criticized for worsening poverty in the same developing countries where the foundation is attempting to relieve poverty. These include companies that pollute heavily and pharmaceutical companies that do not sell into the developing world. In response to press criticism, the foundation announced in 2007 a review of its investments to assess social responsibility. It subsequently cancelled the review and stood by its policy of investing for maximum return, while using voting rights to influence company practices.

The dynasty lost control of peripheral territories bit by bit. In return for promises of support against the British and the French, the Russian Empire took large chunks of territory in the Northeast in 1860. The period of cooperation between the reformers and the European powers ended with the Tientsin Massacre of 1870, which was incited by the murder of French nuns set off by the belligerence of local French diplomats. Starting with the Cochinchina Campaign in 1858, France expanded control of Indochina. By 1883, France was in full control of the region and had reached the Chinese border. The Sino-French War began with a surprise attack by the French on the Chinese southern fleet at Fuzhou. After that the Chinese declared war on the French. A French invasion of Taiwan was halted and the French were defeated on land in Tonkin at the Battle of Bang Bo. However Japan threatened to enter the war against China due to the Gapsin Coup and China chose to end the war with negotiations. The war ended in 1885 with the Treaty of Tientsin (1885) and the Chinese recognition of the French protectorate in Vietnam.

With the advent of the Industrial Revolution, Britain surged ahead of its European rivals. Demand for Indian commodities was boosted by the need to sustain the troops and the economy during the war, and by the increased availability of raw materials and efficient methods of production. As home to the revolution, Britain experienced higher standards of living. Its spiralling cycle of prosperity, demand and production had a profound influence on overseas trade. The company became the single largest player in the British global market. William Henry Pyne notes in his book The Microcosm of London (1808) that:

Tibet has various festivals that are commonly performed to worship the Buddha[citation needed] throughout the year. Losar is the Tibetan New Year Festival. Preparations for the festive event are manifested by special offerings to family shrine deities, painted doors with religious symbols, and other painstaking jobs done to prepare for the event. Tibetans eat Guthuk (barley noodle soup with filling) on New Year's Eve with their families. The Monlam Prayer Festival follows it in the first month of the Tibetan calendar, falling between the fourth and the eleventh days of the first Tibetan month. It involves dancing and participating in sports events, as well as sharing picnics. The event was established in 1049 by Tsong Khapa, the founder of the Dalai Lama and the Panchen Lama's order.

The record attendance for an Everton home match is 78,299 against Liverpool on 18 September 1948. Amazingly, there was only 1 injury at this game-Tom Fleetwood was hit on the head by a coin thrown from the crowd whilst he marched around the perimeter with St Edward's Orphanage Band, playing the cornet. Goodison Park, like all major English football grounds since the recommendations of the Taylor Report were implemented, is now an all-seater and only holds just under 40,000, meaning it is unlikely that this attendance record will ever be broken at Goodison. Everton's record transfer paid was to Chelsea for Belgian forward Romelu Lukaku for a sum of £28m. Everton bought the player after he played the previous year with the team on loan.

Beyoncé's lighter skin color and costuming has drawn criticism from some in the African-American community. Emmett Price, a professor of music at Northeastern University, wrote in 2007, that he thinks race plays a role in many of these criticisms, saying white celebrities who dress similarly do not attract as many comments. In 2008, L'Oréal was accused of whitening her skin in their Feria hair color advertisements, responding that "it is categorically untrue", and in 2013, Beyoncé herself criticized H&M for their proposed "retouching" of promotional images of her, and according to Vogue requested that only "natural pictures be used".

The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. Without predation, herbivores began to over-graze many woody browse species, affecting the area's plant populations. In addition, wolves often kept animals from grazing in riparian areas, which protected beavers from having their food sources encroached upon. The removal of wolves had a direct effect on beaver populations, as their habitat became territory for grazing. Furthermore, predation keeps hydrological features such as creeks and streams in normal working order. Increased browsing on willows and conifers along Blacktail Creek due to a lack of predation caused channel incision because they helped slow the water down and hold the soil in place.

Question: Loose soil from lack of trees along the river bed resulted in?
Answer: channel incision.

When interviewed for Mojo magazine the band said the most amazing sight at Live Aid was to see the audience clapping to "Radio Ga Ga". Brian May stated: "I'd never seen anything like that in my life and it wasn't calculated either. We understood our audience and played to them but that was one of those weird accidents because of the (music) video. I remember thinking 'oh great, they've picked it up' and then I thought 'this is not a Queen audience'. This is a general audience who've bought tickets before they even knew we were on the bill. And they all did it. How did they know? Nobody told them to do it."

The popularization of the Jewish chant may be found in the writings of the Jewish philosopher Philo, born 20 BCE. Weaving together Jewish and Greek thought, Philo promoted praise without instruments, and taught that "silent singing" (without even vocal chords) was better still. This view parted with the Jewish scriptures, where Israel offered praise with instruments by God's own command (2 Chronicles 29:25). The shofar is the only temple instrument still being used today in the synagogue, and it is only used from Rosh Chodesh Elul through the end of Yom Kippur. The shofar is used by itself, without any vocal accompaniment, and is limited to a very strictly defined set of sounds and specific places in the synagogue service.

Question: What is the name of the philosopher who praised music without instruments?
Answer: Philo.

Several Islamic kingdoms (sultanates) under both foreign and, newly converted, Rajput rulers were established across the north western subcontinent (Afghanistan and Pakistan) over a period of a few centuries. From the 10th century, Sindh was ruled by the Rajput Soomra dynasty, and later, in the mid-13th century by the Rajput Samma dynasty. Additionally, Muslim trading communities flourished throughout coastal south India, particularly on the western coast where Muslim traders arrived in small numbers, mainly from the Arabian peninsula. This marked the introduction of a third Abrahamic Middle Eastern religion, following Judaism and Christianity, often in puritanical form. Mahmud of Ghazni in the early 11th century raided mainly the north-western parts of the Indian sub-continent 17 times, but he did not seek to establish "permanent dominion" in those areas.

In Latin, papyri from Herculaneum dating before 79 AD (when it was destroyed) have been found that have been written in old Roman cursive, where the early forms of minuscule letters "d", "h" and "r", for example, can already be recognised. According to papyrologist Knut Kleve, "The theory, then, that the lower-case letters have been developed from the fifth century uncials and the ninth century Carolingian minuscules seems to be wrong." Both majuscule and minuscule letters existed, but the difference between the two variants was initially stylistic rather than orthographic and the writing system was still basically unicameral: a given handwritten document could use either one style or the other but these were not mixed. European languages, except for Ancient Greek and Latin, did not make the case distinction before about 1300.[citation needed]

Victoria wrote to her uncle Leopold, whom Victoria considered her "best and kindest adviser", to thank him "for the prospect of great happiness you have contributed to give me, in the person of dear Albert ... He possesses every quality that could be desired to render me perfectly happy. He is so sensible, so kind, and so good, and so amiable too. He has besides the most pleasing and delightful exterior and appearance you can possibly see." However at 17, Victoria, though interested in Albert, was not yet ready to marry. The parties did not undertake a formal engagement, but assumed that the match would take place in due time.

Between 1836 and 1842 Victorian Aboriginal groups were largely dispossessed[by whom?] of their land. By January 1844, there were said to be 675 Aborigines resident in squalid camps in Melbourne. The British Colonial Office appointed five Aboriginal Protectors for the Aborigines of Victoria, in 1839, however their work was nullified by a land policy that favoured squatters to take possession of Aboriginal lands. By 1845, fewer than 240 wealthy Europeans held all the pastoral licences then issued in Victoria and became a powerful political and economic force in Victoria for generations to come.

On June 17, 2015, 21-year-old Dylann Roof entered the historic Emanuel African Methodist Episcopal Church during a Bible study and killed nine people. Senior pastor Clementa Pinckney, who also served as a state senator, was among those killed during the attack. The deceased also included congregation members Susie Jackson, 87; Rev. Daniel Simmons Sr., 74; Ethel Lance, 70; Myra Thompson, 59; Cynthia Hurd, 54; Rev. Depayne Middleton-Doctor, 49; Rev. Sharonda Coleman-Singleton, 45; and Tywanza Sanders, 26. The attack garnered national attention, and sparked a debate on historical racism, Confederate symbolism in Southern states, and gun violence. On July 10, 2015, the Confederate battle flag was removed from the South Carolina State House. A memorial service on the campus of the College of Charleston was attended by President Barack Obama, Michelle Obama, Vice President Joe Biden, Jill Biden, and Speaker of the House John Boehner.

German record company Odeon is often said to have pioneered the album in 1909 when it released the Nutcracker Suite by Tchaikovsky on 4 double-sided discs in a specially designed package. (It is not indicated what size the records are.) However, Deutsche Grammophon had produced an album for its complete recording of the opera Carmen in the previous year. The practice of issuing albums does not seem to have been widely taken up by other record companies for many years; however, HMV provided an album, with a pictorial cover, for the 1917 recording of The Mikado (Gilbert & Sullivan).

At birth, Victoria was fifth in the line of succession after her father and his three older brothers: the Prince Regent, the Duke of York, and the Duke of Clarence (later William IV). The Prince Regent and the Duke of York were estranged from their wives, who were both past child-bearing age, so the two eldest brothers were unlikely to have any further children. The Dukes of Kent and Clarence married on the same day 12 months before Victoria's birth, but both of Clarence's daughters (born in 1819 and 1820 respectively) died as infants. Victoria's grandfather and father died in 1820, within a week of each other, and the Duke of York died in 1827. On the death of her uncle George IV in 1830, Victoria became heiress presumptive to her next surviving uncle, William IV. The Regency Act 1830 made special provision for the Duchess of Kent to act as regent in case William died while Victoria was still a minor. King William distrusted the Duchess's capacity to be regent, and in 1836 declared in her presence that he wanted to live until Victoria's 18th birthday, so that a regency could be avoided.

Semi-additive is the most common process: The unpatterned board has a thin layer of copper already on it. A reverse mask is then applied. (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces.) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied. The mask is stripped away and a brief etching step removes the now-exposed bare original copper laminate from the board, isolating the individual traces. Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards.

Question: What weight of plating is possible with copper?
Answer: any.

So an additional problem beyond canceling the unwanted reactance is of matching the remaining resistive impedance to the characteristic impedance of the transmission line. In principle this can always be done with a transformer, however the turns ratio of a transformer is not adjustable. A general matching network with at least two adjustments can be made to correct both components of impedance. Matching networks using discrete inductors and capacitors will have losses associated with those components, and will have power restrictions when used for transmitting. Avoiding these difficulties, commercial antennas are generally designed with fixed matching elements or feeding strategies to get an approximate match to standard coax, such as 50 or 75 Ohms. Antennas based on the dipole (rather than vertical antennas) should include a balun in between the transmission line and antenna element, which may be integrated into any such matching network.

Question: How many ohms are in are in a standard coax?
Answer: 50 or 75.

Gearless traction machines are low-speed (low-RPM), high-torque electric motors powered either by AC or DC. In this case, the drive sheave is directly attached to the end of the motor. Gearless traction elevators can reach speeds of up to 20 m/s (4,000 ft/min), A brake is mounted between the motor and gearbox or between the motor and drive sheave or at the end of the drive sheave to hold the elevator stationary at a floor. This brake is usually an external drum type and is actuated by spring force and held open electrically; a power failure will cause the brake to engage and prevent the elevator from falling (see inherent safety and safety engineering). But it can also be some form of disc type like 1 or more calipers over a disc in one end of the motor shaft or drive sheave which is used in high speed, high rise and large capacity elevators with machine rooms(an exception is the Kone MonoSpace's EcoDisc which is not high speed, high rise and large capacity and is machine room less but it uses the same design as is a thinner version of a conventional gearless traction machine) for breaking power, compactness and redundancy(assuming there's at least 2 calipers on the disc), or 1 or more disc brakes with a single caliper at one end of the motor shaft or drive sheave which is used in machine room less elevators for compactness, breaking power, and redundancy(assuming there's 2 brakes or more).

Question: One exception that is not high speed high rise and large capacity is what?
Answer: Kone MonoSpace's EcoDisc.

Nearly two billion people in the developing world are deficient in zinc. In children it causes an increase in infection and diarrhea, contributing to the death of about 800,000 children worldwide per year. The World Health Organization advocates zinc supplementation for severe malnutrition and diarrhea. Zinc supplements help prevent disease and reduce mortality, especially among children with low birth weight or stunted growth. However, zinc supplements should not be administered alone, because many in the developing world have several deficiencies, and zinc interacts with other micronutrients.

The most extreme case was the Soviet Union, and this model may still be followed in some countries: it was a separate service, on a par with the navy or ground force. In the Soviet Union this was called Voyska PVO, and had both fighter aircraft and ground-based systems. This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces. Subsequently these became part of the air force and ground forces respectively
