Temple of Artemis

The Temple of Artemis also known less precisely as Temple of Diana was a temple dedicated to Artemis completed in its most famous phase, approximately 550 BC at Ephesus (in present-day Turkey) under the Achaemenid dynasty of the Persian Empire. Nothing remains of the temple, which was one of the Seven Wonders of the Ancient World. The Temple of Artemis was not the first on its site, where proof of a sanctuary dates as early as the Bronze Age.

The temple was a 120-year project in progress by Croesus of Lydia. It was described by Antipater of Sidon, who compiles a list of the Seven Wonders:

I have set eyes on the wall of lofty Babylon on which is a road for chariots, and the statue of Zeus by the Alpheus, and the hanging gardens, and the colossus of the Sun, and the huge labour of the high pyramids, and the vast tomb of Mausolus; but when I saw the house of Artemis that mounted to the clouds, those other marvels lost their brilliancy, and I said, "Lo, apart from Olympus, the Sun never look on aught (anything) so grand".

Keyword stuffing in SEO

Keyword stuffing is measured to be an immoral search engine optimization (SEO) method. Keyword stuffing happens when a web page is loaded with keywords in the Meta tags or in content. The replication of words in Meta tags may explain why many search engines no longer use these tags.
Keyword stuffing can be known to be either a white hat or a black hat tactic, conditional on the context of the technique, and the opinion of the person judging it. While a great deal of keyword stuffing is employed to help in spamdexing, which is of little gain to the user, keyword stuffing in certain situation is designed to help the user and not skew results in a misleading manner. Whether the term carries a pejorative or neutral connotation is in need of whether the practice is used to pollute the results with pages of little significance, or to direct traffic to a page of importance that would have otherwise been de-emphasized due to the search engine's inability to interpret and recognize related ideas.

Screen Printing Technique

A screen made of a piece of porous, finely woven fabric including silk, polyester or nylon is stretched over a wooden or aluminum frame. Areas of the screen are blocked off with a non-permeable material (a stencil) which in revolve is a negative of the image to be printed.

The screen is placed on top of a piece of paper or fabric. Ink is placed on top of the screen, and a rubber blade is used to spread the ink consistently across the screen. The ink passes through the open spaces in the screen onto the paper or fabric below; followed by lifting of the screen. The screen can be again being re-used after cleaning. For multiple color screens printing on the same surface, the ink is allowed to dry and then the entire process is repeated with another screen and different color of ink.

Swaption

A swaption is an option granting its owner the right but not the obligation to enter into a fundamental swap. Although options can be traded on a diversity of swaps, the term "swaption" typically refers to options on interest rate swaps.

There are two types of swaption contracts:

A payer swaption gives the owner of the swaption the right to come into a swap where they pay the fixed leg and obtain the floating leg.
A receiver swaption gives the owner of the swaption the right to enter into a swap where they will receive the fixed leg, and pay the floating leg.
The buyer and seller of the swaption agree on:

The premium (price) of the swaption
the strike rate (equal to the fixed rate of the underlying swap)
Length of the option period (which frequently ends two business days prior to the start date of the underlying swap),
the term of the underlying swap,
Notional amount,
Amortization, if any
Frequency of settlement payments on the underlying swap.
