<span>During a sleep study electrodes are attached to the scalp, near the chin, near the eyes, on the upper chest, and the lower legs. Sensors are also attached to the upper lip and either the finger or the ear. The electrodes on the scalp measure brain waves or EEG to monitor the different stages of sleep. The electrodes near the eyes record eye movement and the electrodes on the chin record muscle activity to also provide data for determining sleep stages. The upper chest electrodes monitor heart activity. The lower leg electrodes show leg muscle activity during sleep. The upper lip sensor monitors breathing. The sensor on the finger or ear tell the doctor about the oxygen levels in the patients blood. Various other sensors may be used for studying specific areas of concern t the discretion of the sleep lab technician.</span>

What is the cost of credit?
Credit costs an additional amount of money. The borrower must repay the amount of the loan–the principal–plus interest to the lender. Generally, repayments are made on an installment basis over the life of the loan. In some instances, one payment of principal and interest is made at the maturity of the loan.

Answer:
In the decades following the Civil War, the United States emerged as an industrial giant. Old industries expanded and many new ones, including petroleum refining, steel manufacturing, and electrical power, emerged. Railroads expanded significantly, bringing even remote parts of the country into a national market economy.
Industrial growth transformed American society. It produced a new class of wealthy industrialists and a prosperous middle class. It also produced a vastly expanded blue collar working class. The labor force that made industrialization possible was made up of millions of newly arrived immigrants and even larger numbers of migrants from rural areas. American society became more diverse than ever before.
Not everyone shared in the economic prosperity of this period. Many workers were typically unemployed at least part of the year, and their wages were relatively low when they did work. This situation led many workers to support and join labor unions. Meanwhile, farmers also faced hard times as technology and increasing production led to more competition and falling prices for farm products. Hard times on farms led many young people to move to the city in search of better job opportunities.
Americans who were born in the 1840s and 1850s would experience enormous changes in their lifetimes. Some of these changes resulted from a sweeping technological revolution. Their major source of light, for example, would change from candles, to kerosene lamps, and then to electric light bulbs. They would see their transportation evolve from walking and horse power to steam-powered locomotives, to electric trolley cars, to gasoline-powered automobiles. Born into a society in which the vast majority of people were involved in agriculture, they experienced an industrial revolution that radically changed the ways millions of people worked and where they lived. They would experience the migration of millions of people from rural America to the nation's rapidly growing cities
