EROEI
Energy Return on Energy Invested. The ratio of the amount of energy needed to generate a unit of energy from a fuel source. When oil was first produced over 150 years ago the EROEI was 40 (or more) to 1. The oil gushed out of the ground. Just 30 years ago it was as high as 20:1. Today, the oil EROEI is variously reported as 2.5 to 1.2 to 1 for light sweet crude. As Peak Oil occurs, oil shale production is expected to see an EROEI of less than 1. That means it takes more than one energy unit to produce a single unit of energy from the oil shale. Thus, it doesn’t matter how much it costs, because the extraction operation will have become an energy sink.

Federal Emergency Management Agency, The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security, initially created by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders. On 1 April 1979. The primary purpose of FEMA is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the president that FEMA and the federal government respond to the disaster. FEMA also provides these services for territories of the United States, such as Puerto Rico. The only exception is when an emergency and/or disaster occurs on federal property or to a federal asset, for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle Columbia in the 2003 return-flight disaster.

Fiat Currency
Fiat money is money that derives its value from government regulation or law: the initial value of fiat money is established by government decree. The term fiat currency is also used when the fiat money is used as the main currency of the country. The term derives from the Latin fiat, meaning “let it be done” or “it shall be”.
FICA
Federal Insurance Contributions Act (FICA) tax is a United States payroll (or employment) tax imposed by the federal government on both employees and employers to fund Social Security and Medicare —federal programs that provide benefits for retirees, the disabled, and children of deceased workers. Social Security benefits include old-age, survivors, and disability insurance (OASDI); Medicare provides hospital insurance benefits for the elderly. The amount that one pays in payroll taxes throughout one’s working career is associated indirectly with the social security benefits annuity that one receives as a retiree.[citation needed] This has caused some to claim that the payroll tax is not a tax because its collection is tied to a benefit. The United States Supreme Court decided in Flemming v. Nestor (1960) that no one has an accrued property right to benefits from Social Security.

Galil
The Galil is a family of Israeli small arms designed by Yisrael Galil and Yaacov Lior in the late 1960s and produced by Israel Military Industries Ltd (now Israel Weapon Industries Ltd) of Ramat HaSharon. The weapon system consists of a line chambered for the intermediate 5.56x45mm NATO caliber with either the M193 or SS109 ball cartridge and several models designed for use with the 7.62x51mm NATO rifle round. It is named after one of its inventors, Yisrael Galil.
Garand
The M1 Garand (officially designated as United States Rifle, Caliber .30, M1 and later simply Rifle, Caliber .30, M1, and also abbreviated as US Rifle, Cal. .30, M1), was the first semi-automatic rifle to be generally issued to the infantry of any nation. Called “the greatest battle implement ever devised” by General George S. Patton, the Garand officially replaced the bolt-action M1903 Springfield as the standard service rifle of the United States Armed Forces in 1936 and was subsequently replaced by the selective fire M14 in 1957. However, the M1 continued to be used in large numbers until 1963 and to a lesser degree until 1966.

In 2002, following coverage of concerns about deflation in the business news, Bernanke gave a speech about the topic. In that speech, he mentioned that the government in a fiat money system owns the physical means of creating money. Control of the means of production for money implies that the government can always avoid deflation by simply issuing more money. He said “The U.S. government has a technology, called a printing press (or today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at no cost.” (He referred to a statement made by Milton Friedman about using a “helicopter drop” of money into the economy to fight deflation.) Bernanke’s critics have since referred to him as “Helicopter Ben” or to his “helicopter printing press.” In a footnote to his speech, Bernanke noted that “people know that inflation erodes the real value of the government’s debt and, therefore, that it is in the interest of the government to create some inflation.” For example, while Greenspan publicly supported President Clinton’s deficit reduction plan and the Bush tax cuts, Bernanke, when questioned about taxation policy, said that it was none of his business, his exclusive remit being monetary policy, and said that fiscal policy and wider society related issues were what politicians were for and got elected for. But Bernanke has been identified by the Wall Street Journal and a close colleague as a “libertarian-Republican” in the mold of Alan Greenspan.

Lines of drift
Also known as, “Channelized Areas”. Natural lines of drift are those paths across terrain that are the most likely to be used when going from one place to another. These paths are paths of least resistance: those that offer the greatest ease while taking into account obstacles (e.g. rivers, cliffs, dense unbroken woodland, etc.) and modes of transit (e.g. pedestrian, automobile, horses.). Common endpoints or fixed points may include water sources, food sources, and obstacle passages such as fords or bridges. Local paths may be derived from game trails or artificial paths created by utility lines or political boundaries. Property ownership and land use may also be factors in determining local variation. Improved paths may also be partially defined by the logistics necessary to build roads or railways.

Option
An agreement that grants the options buyer the right, but not the obligation, to buy or sell an asset or commodity at a specified “strike” price on or before a certain date. A call option grants the right to buy at the specified strike price, and so it pays off if the market price for the underlying item rises above that mark. A put option grants the right to sell as the strike price and pays off when the market price falls below the strike price. On the other hand, an option seller or “options writer” has the obligation to pay when the options buyer exercises their right. Options are traded on both exchanges and OTC markets. For example, party A buys a call that grants them the right to buy 1 million Euros at $0.9400 in September.

In computer networking, a packet is a formatted unit of data carried by a packet mode computer network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a series of bytes, characters, or bits alone. When data is formatted into packets, the bitrate of the communication medium can be better shared among users than if the network were circuit switched.

R4
The R4 is a 5.56mm assault rifle that was introduced into service with the South African Defence Force (SADF) in 1982, replacing the earlier 7.62mm FN FAL rifle, that was manufactured in South Africa under a license agreement from Fabrique Nationale as the R1.

R
Rads, The roentgen (R, also röntgen) is an obsolete unit of measurement for the kerma of X-rays and gamma rays up to 3 MeV. It is named after the German physicist Wilhelm Röntgen, the man who discovered X-rays. Originating in 1908, this unit has been redefined and renamed over the years. It was last defined by the US National Institute of Standards and Technology (NIST) in 1998 as 2.58×10−4 C/kg, (1 C/kg = 3876 R,) with a recommendation that the definition be given in every document where the roentgen is used. One roentgen of air kerma deposits 0.00877 gray (0.877 rad) of absorbed dose in dry air, or 0.0096 gray (0.96 rad) in soft tissue. One roentgen (air kerma) of X-rays may deposit anywhere from 0.01 to more than 0.04 gray (1 to 4 rad) in bone depending on the beam energy. This tissue-dependent conversion from roentgen to rad is called the F-factor in radiotherapy contexts. The conversion depends on the ionizing energy of a standard medium, which is ambiguous in the latest NIST definition. Even where the standard medium is fully defined, the ionizing energy of the calibration and target mediums are often not precisely known.

Schumer
Charles Ellis “Chuck” Schumer (/ˈʃuːmər/; born November 23, 1950) is the senior United States Senator from New York and a member of the Democratic Party. First elected in 1998, he defeated three-term Republican incumbent Al D’Amato by a margin of 55%–44%. Schumer was re-elected in 2004 by a margin of 71%–24% and in 2010 by a margin of 66%–33%. Before his election to the U.S. Senate, Schumer served in the United States House of Representatives from 1981 to 1999. He represented New York’s 16th congressional district, which was later redistricted to the 10th congressional district in 1983 and to the 9th congressional district in 1993. A native of Brooklyn and graduate of Harvard College and Harvard Law School, he was a three-term member of the New York State Assembly, serving from 1975 to 1980. Schumer was chairman of the Democratic Senatorial Campaign Committee from 2005 to 2009, in which post he oversaw a total of 14 Democratic gains in the Senate in the 2006 and 2008 elections. Elected Vice Chairman of the Democratic Caucus in the Senate, in 2006,[1] he is the third-ranking Democrat in the Senate, behind Senate Majority Leader Harry Reid and Senate Majority Whip Dick Durbin. In November 2010, he was also chosen to hold the additional role of chairman of the Senate Democratic Policy Committee starting at the opening of the 112th Congress.

The Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers.
Its name was changed in 1994 during the Presidency of Bill Clinton to reflect its broader mission. It is a relatively small agency, currently comprising about 12,000 employees. Its mission is to improve, protect, and conserve natural resources on private lands through a cooperative partnership with local and state agencies. While its primary focus has been agricultural lands, it has made many technical contributions to soil surveying, classification and water quality improvement. One example is the Conservation Effects Assessment Project (CEAP), set up to quantify the benefits of agricultural conservation efforts promoted and supported by programs in the Farm Security and Rural Investment Act of 2002 (2002 Farm Bill). NRCS is the leading agency in this project.

SEAL
Sea Air Land, The United States Navy’s Sea, Air, and Land (SEAL) teams are the U.S. Navy’s principal special operations force and a part of the Naval Special Warfare Command (NSWC) and SOCOM. “SEAL” is always capitalized in reference to members of the Naval Special Warfare community. The acronym is derived from their capacity to operate at sea, in the air, and on land. In the War on Terror, SEALs have been utilized almost exclusively for land-based operations, including Direct Action, Hostage Rescue, Counter Terrorism, Special Reconnaissance, unconventional warfare, manhunts and foreign internal defense operations. SEALs are male members of the United States Navy. An exchange program with the Coast Guard, which graduated three Coast Guardsmen as SEALs, was suspended in 2011. The CIA’s highly secretive Special Activities Division (SAD) and more specifically its elite Special Operations Group (SOG) recruits operators from the SEAL Teams. Joint Navy SEALs and CIA operations go back to the famed MACV-SOG during the Vietnam War. This cooperation still exists today and is seen in the wars in Iraq and Afghanistan, and in the finding and killing of Osama bin Laden in Pakistan. The Navy SEALs are the least integrated of all US military groups, with African Americans representing less than 2% of SEAL officers. The Navy has recently announced programs to try to remedy this systemic issue with the SEAL program.

Shank’s Mare
Scottish slang dating from the eighteenth century. There was a verb, to shank or to shank it, meaning to go on foot. This is from standard English shank for the part of the leg from the knee to the ankle, which comes from Old English sceanca, the leg bone. This verb developed into shank’s naig or shank’s naigie (where the second words are local forms of nag, a horse) and later into shank’s mare. It was a wry joke: “I haven’t got a horse of my own for the journey, so I’ll use Shank’s mare to get there.” (Meaning, I’ll go on my own two feet.) This supposed link with a person called Shank explains why the first word is often capitalised. Another form, now more common in Britain, is shank’s pony.

Tor
Tor (short for The Onion Router) is a system intended to enable online anonymity. Tor client software directs internet traffic through a worldwide volunteer network of servers to conceal a user’s location or usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult to trace Internet activity, including “visits to Web sites, online posts, instant messages and other communication forms”, back to the user and is intended to protect users’ personal freedom, privacy, and ability to conduct confidential business by keeping their internet activities from being monitored. “Onion Routing” refers to the layered nature of the encryption service: The original data are encrypted and re-encrypted multiple times, then sent through successive Tor relays, each one of which decrypts a “layer” of encryption before passing the data on to the next relay and, ultimately, its destination. This reduces the possibility of the original data being unscrambled or understood in transit. The Tor client is free software and use of the Tor network is free of charge.

The World Trade Center is a complex of buildings under construction in Lower Manhattan, New York City, United States, replacing an earlier complex of seven buildings with the same name on the same site. The original World Trade Center featured landmark twin towers, which opened on April 4, 1973 and were destroyed in the September 11 attacks of 2001, along with 7 World Trade Center. The other buildings in the complex were damaged in the attacks, and their ruins were eventually demolished. The site is being rebuilt with five new skyscrapers and a memorial to the casualties of the attacks. As of November 2011, only one skyscraper has been completed; the other four are expected to be completed before 2020. One World Trade Center will be the lead building for the new complex, reaching more than 100 stories at its completion. It became the tallest building in New York City on April 30, 2012, and is expected to be finished by 2013. A sixth tower is awaiting confirmation.

XM177E2
In April 1967, the Army purchased 510 Colt 629 Commandos for use by troops assigned to the Military Assistance Command, Vietnam Studies and Observations Group (MACV-SOG), and designated them XM177E2. Delivery was completed by the end of September 1967. The Air Force adopted a similar model without the forward assist feature as the GAU-5A/A. Sources debate whether or not this was a Colt Model 630 or 649. According to John Plaster and other sources, the lack of 30 round magazines continued to be problematic and SOG operators resorted to pooling their personal resources and purchasing the larger capacity magazines on the civilian U.S. market. Problems with range, accuracy, barrel fouling, and usage of tracer bullets continued to plague the XM177 series, but Colt estimated that it would take a six-month $400,000 program to do a complete ballistic and kinematic study. There were also recommendations for a 29-month $635,000 research and development program. Both recommendations were declined by the U.S. military as American ground force involvement in the Vietnam War was gradually winding down. Production of the CAR-15 Commando ended in 1970.
