Theoretically, 3DES should provide 168 bits of security. But because of the design, the NIST later said it only provides 80 bits of security. That can be broken by a modern computer and thus the cipher should be considered broken.

1925 Geneva Protocol
The Geneva Protocol of 1925 (The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare) was a law that made it illegal to fight with chemical or biological weapons in war. The Geneva protocol was signed on June 17, 1925 and the protocol was entered into force on January 8, 1928. Before, it was signed by some countries like the United Kingdom and France originally. Any country who has signed this Protocol must follow it.
After World War I, the Geneva Protocol was made from the treaties signed with Austria, Hungary and Bulgaria. The use of chemical weapons began in WWI when one million deaths resulted from chemical weapons.
After signing the treaty, some countries wanted to change it so that they would not have to follow it if the country fighting them did not follow the treaty. Because of this, many countries like France and United Kingdom withdrew from it. Others, like the United States still follow it but with this extra condition.
Fledge
Fledge is the stage in a young bird's life when the feathers and wing muscles become developed enough for flight. It also describes the act of a chick's parents raising it until it is fully grown. A young bird that has recently fledged but still needs care and feeding is called a fledgling.
In ornithology, fledging has many meanings, depending on species. Birds are sometimes considered fledged once they leave the nest, even if they still cannot fly.
Rat snake
Rat snakes are medium to large snakes that can be found mostly in the northern hemisphere. They feed primarily on rodents and birds and, with some species being over 3 m (10 feet), they are on the top levels of some food chains. Many species make attractive pets and one, the corn snake, is one of the most popular reptile pets in the world. Other species can be very sensitive and sometimes aggressive, but the bites are not dangerous. Rat snakes were long thought to be completely nonvenomous, but recent studies have shown that some do have harmlessly small amounts of venom in them. When frightened, rat snakes may freeze, which is why a lot has been killed in traffic.
Rat snakes are commonly kept as pets. The corn snake especially is one of the most popular pet reptiles, and belongs to the rat snake family.
Inductively coupled plasma mass spectrometry
Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry that is highly sensitive. It can see a range of metals and several non-metals at concentrations below one part in 10 (part per trillion). It is based on hooking together an inductively coupled plasma as a method of producing ions (ionization) with a mass spectrometer as a method of separating and detecting the ions. Many chemists use Argon as a carrier gas to make the plasma. The machine sends the sample ions through a series of small cones. The cones let the plasma ions slowly enter the vacuum chamber of the mass spectrometer.
In trace elemental analysis, the method has advantages of high speed, precision and sensitivity compared to atomic absorption techniques. Analysis of lower concentrations at the same time is more prone to disruption by trace contaminants in labware and reagents used. Some analytes can not work with ICP-MS. Verification of analysis results requires additional work.
The variety of applications exceeds that of ICP-OES and includes isotopic speciation. Because ICP-MS can help make atom bombs, ICP-MS hardware is a subject for special exporting regulations.
The Birds of America
The Birds of America is a book by naturalist and painter John James Audubon. It includes illustrations of a wide variety of birds of the United States. It was first published between 1827 and 1838, in Edinburgh and London.
The work is of hand-coloured, life-size prints, made from engraved plates, measuring around . It includes images of six birds that are now extinct: Carolina Parakeet, Passenger Pigeon, Labrador Duck, Great Auk,
Esquimaux Curlew, and Pinnated Grouse.
Charles Wright (poet)
Charles Wright (born August 25, 1935) is an American poet. He was awarded the National Book Award (1983) for "Country Music: Selected Early Poems" and the Pulitzer Prize for Poetry (1998) for "Black Zodiac".
4-H
4-H in the United States is a youth organization administered by the National Institute of Food and Agriculture of the United States Department of Agriculture (USDA), with the mission of "engaging youth to reach their fullest potential while advancing the field of youth development." The name represents four personal development areas for the organization's members: head, heart, hands, and health. The organization has over 6.5 million members in the United States. Members are five to 19 years old, in approximately 90,000 clubs.
The goal of 4-H is to develop citizenship, leadership, responsibility and life skills of youth through experiential learning programs and a positive youth development approach. Many people think of 4-H as an agriculturally-focused organization as a result of its history. But 4-H today focuses on citizenship, healthy living, science, engineering, and technology programs.
Today, 4-H and related programs exist in over eighty countries around the world. The organization and administration varies from country to country. Each of these programs operates independently. They cooperate in international exchanges, global education programs, and communications.
The 4-H motto is "To make the best better", while its slogan is "Learn by doing" (sometimes written as "Learn to do by doing").
The start of 4-H began around 1900, with the work of several people in different parts of the United States. The focal point of 4-H has been the idea of practical and hands-on learning, which came from the desire to make public school education more connected to rural life. Early programs tied both public and private resources together to benefit rural youth.
During this time, researchers at agricultural experiment stations of the land-grant universities and USDA saw that adult farmers did not readily accept new agricultural discoveries, but educators found that youth would experiment with these new ideas and then share their experiences and successes with the adults. So, rural youth programs became a way to introduce new agriculture technology to the adults.
A. B. Graham started one of the youth programs in Clark County, Ohio, in 1902, which is considered the birth of the 4-H program in the United States. The first club was called "The Tomato Club" or the "Corn Growing Club". T.A. "Dad" Erickson of Douglas County, Minnesota, started local agricultural after-school clubs and fairs also in 1902. Jessie Field Shambaugh developed the clover pin with an H on each leaf in 1910, and, by 1912, they were called 4-H clubs. The national 4-H organization was formed in 1914. When the United States Congress created the Cooperative Extension Service (CES) of the USDA by passage of the Smith-Lever Act of 1914, it included within the CES charter the work of various boys' and girls' clubs involved with agriculture, home economics and related subjects. By 1924, these clubs became organized as 4-H clubs, and the clover emblem was adopted.
The first 4-H camp was held in Randolph County, West Virginia. Originally, these camps were for what was referred to as "Corn Clubs". Campers slept in corn fields, in tents, only to wake up and work almost the entirety of each day. Superintendent of schools G. C. Adams began a boys' corn club in Newton County, Georgia, in 1904. However, the city of Jacksboro, Texas, also stakes a claim to having the first forerunner to 4-H in 1910.
