The Greek Economy :: essays research papers fc

The Greek Economy Agriculture The Greek economy depends a lot on agriculture. One quarter of the Greek workforce is engaged in farming, and agriculture constitutes about 15% of the domestic production. Not much attention has been drawn on the agricultural sector of the economy. The farms are pretty small, the division of inheriting land has reduced the average size to 3,4 hectares (8 acres) and it is really difficult to use mechanised equipment efficiently. Yields are also low due to the dryness and erosion of the soil. Let's take a look at the yearly output of some major crops: tobacco 142000, wheat 2.6 million, tomatoes 1.9 million, oranges 780000, corn 2.1 million, sugar beet 1.9 million, grapes 1.6 million, olives 1.5 million, potatoes 850000 and cotton 222000. Livestock included some 10.8 million sheep, 3.5 million goats, 800000 head of cattle, 31 million poultry and 1.2 million pigs. Forestry and Fishing The Greek government owns the two-thirds of the forestland and has materialised her plans i.e. to replace the trees that were destroyed during World War II. About 2.9 million cu m of timber were annually cut in the late 80's and approximately the 75% of the harvest was hardwood. Fish exports are limited because of the widespread consumption of fish products within Greece. However in recent years thousands of tons of fish are exported each year, due to the ever increasing development of fish farms in the country. In the late 80's the annual catch totalled 135000 tons, from which 80% was consumed within Greece. Sponges are the main marine product exported. Mining Mining is of little importance to the Greek economy. We should mention though the annual output of minerals in tons: bauxite 2.3 million, iron ore 1.3 million and magnesite 884400. Also, about 279200 cu m of marble were quarried. Petroleum, salt, chromium, silver, zinc were also produced. Manufacturing Approximately one fifth of the Greek workforce is engaged in manufacturing, which contributes 18% of the annual gross production. The manufactured products include: food, beverages, tobacco, textiles, clothing, chemicals, cement and wine. Athens is the manufacturing center of Greece. Currency and Banking The national currency of Greece is drachma. The central banking institution is the Bank of Greece. The biggest banks of Greece are the National Bank of Greece, with 470 domestic branches and the Agricultural Bank of Greece with 420 branches. Foreign Trade Generally Greece spends each year much more on imports than it receives from exports. This "imbalance" is offset to a certain extent by tourist revenues and by remittances from Greeks living abroad. In the 80's the imports totalled 3 trillion drachmas and exports earned 1.5 trillion drachmas.

Secant Methods Application

SUBMITTED TO: sir sajid presentation on application of secant method April 16, 2013 MCS 1st sem ————————————————- ROLL # 31 to 40 SECANT METHOD * The  Secant  command numerically approximates the roots of an algebraic function,  f, using a technique similar to Newton's method but without the need to evaluate the derivative of  function. * Given an expression  f  and an initial approximate  a, the  Secant  command computes a sequence,  =, of approximations to a root of  f, where  Ã‚  is the number of iterations taken to reach a stopping criterion. The  Secant  command is a shortcut for calling the  Roots  command with the  method=secant  option Advantages of secant method * It converges at faster than a linear rate, so that it is more rapidly convergent than the bisection method. * It does not require use of the derivative of the function, something that is not available in a number of applications. * It requires only one function evaluation per iteration, as compared with Newton’s method which requires two Disadvantages of secant method * It may not converge. * There is no guaranteed error bound for the computed iterates. * It is likely to have difficulty if f? (? ) = 0.This means the x-axis is tangent to the graph of y = f (x) at x = ?. * Newton’s method generalizes more easily to new methods for solving simultaneous systems of nonlinear equations. APPLICATION OF SECANT METHOD 1. You are working for a start-up computer assembly company and have been asked to determine the minimum number of computers that the shop will have to sell to make a profit. The equation that gives the minimum number of computers to be sold after considering the total costs and the total sales is 2. Use the secant method of finding roots of equations to find the minimum number of computers that need to be sold to make a profit. Conduct three iterations to estimate the root of the above equation. Find the absolute relative approximate error at the end of each iteration and the number of significant digits at least correct at the end of each iteration. 3. Today the most important application of secant method is to predicting the earthquake performance of structures. sozen has been credited with having developed progenitor procedures. 4. Based on the sinusoidal pulse width modulation technology and regular sampling  method, the switching time point’s calculation formulas  of  tangent  method  and  secant  method  are established.This paper analyses the precision  of  switching turn-on and turn-off time point, and compare these switching time points. Calculation results show that SPWM pulses generated by tangent  method  and  secant  method  are closest to the pulse generated by natural sampling, the THD is also smaller than by regular sampling. 5. Secant method is used to determine the optimal stage. ( maximize or minimize ) the problem or solution. Example You are working for a start-up computer assembly company and have been asked to determine the minimum number of computers that the shop will have to sell to make a profit.The equation that gives the minimum number of Computers ‘x’ to be sold after considering the total costs And the total sales is: Solution Use the Secant method of finding roots of equations to find * The minimum number of computers that need to be sold to make a profit. Conduct three iterations to estimate the root of the above equation. * Find the absolute relative approximate error at the end of each iteration, and * The number of significant digits at least correct at the end of each iteration.

The Berlin Patient Timothy Ray Brown - 1431 Words

The Berlin Patient Timothy Ray Brown, gained his title as â€Å"The Berlin Patient† after being the first man successfully cured of HIV (human immunodeficiency virus) in 2008, Berlin. Brown has been battling with HIV for 11 years with antiretroviral drugs since 1995 when he was diagnosed. Then in 2006, he was being diagnosed with acute myeloid leukemia, another disease that would put his life in danger. Acute myeloid leukemia is a type of cancer that attacks the bone marrow and spread to blood.[9] To treat his new deadly disease, Brown has tried radiation and chemotherapy which both did not seem to be successful in helping him. In 2007 and 2008 he made the decision of going for a bone marrow transplant. Brown’s oncologist has chose a bone marrow donor with a genetic mutation known as delta 32 which is found in 1 to 2 percent of the people in Northern Europe. For people with the delta 32 mutation, they are very likely to be immune to Smallpox, the Bubonic Plague and resistant to HIV and A IDS. [10] Focusing on how HIV is prevented by this mutation, HIV virus usually enters a cell through the cell’s CCR5 receptor and fuse into the cell that will eventually divide itself and spread throughout the patient’s body, infecting the patient with cells that is infected with HIV viruses. With the delta 32 mutation, the entry of HIV is blocked due to their misshapen CCR5 protein. Immunity to HIV is only present to homozygous carriers for the delta 32 mutation on both genes.
