Hanging Gardens of Babylon

The Hanging Gardens of Babylon is also known as the Hanging Gardens of Semiramis near present-day Al Hillah in Iraq, formerly Babylon are precise one of the original Seven Wonders of the World. They were built by Nebuchadnezzar II approximately 600 BC. He is reported to have constructed the gardens to please his wife, Amytis of Media, who longed for the trees and aromatic plants of her homeland.The gardens were damaged by several earthquakes after the 2nd century BCE.

The lush Hanging Gardens are broadly documented by Greek historians such as Strabo and Diodorus Siculus. Through the ages, the location may have been confused with gardens that exist at Nineveh, since tablets from there clearly show gardens. Writings on these tablets explain the possible use of something similar to an Archimedes' screw as a process of raising the water to the necessary height.

Formal wear

Formal wear or formal dress is an ordinary fashion term used to explain clothing apt for formal procedures, with weddings, debutante cotillions, etc. Western formal dress has had a ubiquitous influence on styles in different countries. It is almost forever the normal used in countries where there is no formal edition of the national costume. Foreign dignitaries and honored visitors in Western countries frequently take on Western evening dress on formal and state occasions, even though it is not unusual for distinguished persons to wear the formal versions of their common dress if such exists; the sari and the dashiki are easily-recognizable for examples.

Unlike for the majority part of the fashion world, the styles of formal dress take their names from men's wear rather than female dress. Traditional 'rules' oversee men's formal dress; these are definitely observed at socially traditional events for example royal weddings, and give as starting points for the creative formal wear seen at high school proms, formal dances and in free time industry awards shows.

Credit rating

A credit rating assesses the credit worthiness of an individual, corporation, or even a country. Credit ratings are considered from financial history and current assets and liabilities. Typically, a credit rating tells a lender or investor the probability of the subject being capable to pay back a loan. However, in recent years, credit ratings have also been used to adjust insurance premiums, determine employment eligibility, and establish the amount of a utility or leasing deposit.

A poor credit rating indicates a high risk of non-payment on a loan, and thus leads to high interest rates or the denial of a loan by the creditor.

Yield curve

In finance, the yield curve is the relation between the interest rate and cost of borrowing and the time to maturity of the debt for a given borrower in a given currency. For example, the current U.S. dollar interest rates paid on U.S. Treasury securities for various maturities are closely watched by many traders, and are normally plotted on a graph such as the one on the right which is informally called "the yield curve." More formal mathematical descriptions of this relation are often called the term arrangement of interest rates.

The yield of a debt instrument is the annualized percentage increase in the worth of the investment. For instance, a bank account that pays an interest rate of 4% per year has a 4% yield. In general the percentage per year that can be earned is dependent on the length of time that the money is invested. For example, a bank may offer a "savings rate" higher than the normal checking account rate if the customer is prepared to leave money unharmed for five years. Investing for a period of time t gives a yield Y (t).

This function Y is called the yield curve, and it is often, but not always, an increasing function of t. Yield curves are used by fixed income analysts, who analyze bonds and connected securities, to understand conditions in financial markets and to seek trading opportunities. Economists make use of curves to understand economic conditions.
