| Central Intelligence Agency |
The Central Intelligence Agency (CIA ), known informally as the Agency and historically as the Company, is a civilian foreign intelligence service of the federal government of the United States, officially tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT) and performing covert actions. As a principal member of the United States Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet of the United States. |
| Activity diagram |
Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities. |
| Risk factor |
In epidemiology, a risk factor or determinant is a variable associated with an increased risk of disease or infection.: 38 Due to a lack of harmonization across disciplines, determinant, in its more widely accepted scientific meaning, is often used as a synonym. The main difference lies in the realm of practice: medicine (clinical practice) versus public health. |
| Risk factors of schizophrenia |
Risk factors of schizophrenia include many genetic and environmental phenomena. The prevailing model of schizophrenia is that of a special neurodevelopmental disorder with no precise boundary or single cause (i.e. |
| Affect theory |
Affect theory is a theory that seeks to organize affects, sometimes used interchangeably with emotions or subjectively experienced feelings, into discrete categories and to typify their physiological, social, interpersonal, and internalized manifestations. The conversation about affect theory has been taken up in psychology, psychoanalysis, neuroscience, medicine, interpersonal communication, literary theory, critical theory, media studies, and gender studies, among other fields. |
| Special operations |
Special operations (S.O.) are military activities conducted, according to NATO, by "specially designated, organized, selected, trained, and equipped forces using unconventional techniques and modes of employment". Special operations may include reconnaissance, unconventional warfare, and counter-terrorism actions, and are typically conducted by small groups of highly-trained personnel, emphasizing sufficiency, stealth, speed, and tactical coordination, commonly known as "special forces". |

| Proven reserves |
Proven reserves (also called measured reserves, 1P, and reserves) is a measure of fossil fuel energy reserves, such as oil reserves, natural gas reserves, and coal reserves. It is defined as the "[q]uantity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering data, to be recoverable from well established or known reservoirs with the existing equipment and under the existing operating conditions." A reserve is considered proven if it is probable that at least 90% of the resource is recoverable by economically profitable means. |
| List of countries by coal reserves |
This is a list of countries by proven oil reserves. Proven reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated, with a high degree of confidence, to be commercially recoverable from a given date forward from known reservoirs and under current economic conditions. |

| Free cash flow to equity |
In corporate finance, free cash flow to equity (FCFE) is a metric of how much cash can be distributed to the equity shareholders of the company as dividends or stock buybacks—after all expenses, reinvestments, and debt repayments are taken care of. It is also referred to as the levered free cash flow or the flow to equity (FTE). |
| Cash flow forecasting |
Cash flow forecasting is the process of obtaining an estimate or forecast of a company's future financial position; the cash flow forecast is typically based on anticipated payments and receivables.\nSee Financial forecast for general discussion re methodology. |
| Natural gas |
Natural law (Latin: ius naturale, lex naturalis) is a system of law based on a close observation of human nature, and based on values intrinsic to human nature that can be deduced and applied independently of positive law (the express enacted laws of a state or society). According to natural law theory, all people have inherent rights, conferred not by act of legislation but by "God, nature, or reason." Natural law theory can also refer to "theories of ethics, theories of politics, theories of civil law, and theories of religious morality."In the Western tradition it was anticipated by the Pre-Socratics, for example in their search for principles that governed the cosmos and human beings. |
| United States energy independence |
US energy independence is the idea of eliminating the need for the United States to import petroleum and other foreign sources of energy, either entirely or with the exception of imports from Canada and Mexico, in which case it is called North American energy independence. Energy independence is espoused by those who want to leave the US unaffected by global energy supply disruptions, and to restrict reliance upon politically unstable states for its energy security. |
| Economy of Iran |
The economy of Iran is a mixed economy with a large state-owned sector and is the largest in the Middle East in terms of nominal GDP. It is the world's 23rd largest by purchasing power parity (PPP). Some 60% of Iran's economy is centrally planned. |
| Oil refinery |
An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemicals feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. |
| Petroleum industry |
The petroleum industry, also known as the oil industry or the oil patch, includes the global processes of exploration, extraction, refining, transportation (often by oil tankers and pipelines), and marketing of petroleum products. The largest volume products of the industry are fuel oil and gasoline (petrol). |
| Engen Petroleum |
Engen Petroleum is a South African oil company focusing on the downstream refined petroleum products market and related businesses. The company’s core functions are the refining of crude oil, the marketing of primary refined petroleum products and the provision of convenience services via an extensive retail network. |
| Human impact on the environment |
Human (or anthropogenic) impact on the environment refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. |
| Petroleum product |
Petroleum products are materials derived from crude oil (petroleum) as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. |
| Research and development |
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. |
| Deepwater Horizon oil spill |
The Deepwater Horizon oil spill (also referred to as the "BP oil spill") was an industrial disaster that began on 20 April 2010, in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. The U.S. federal government estimated the total discharge at 4.9 Mbbl (210 million US gal; 780,000 m3). |
| Unintended consequences |
In the social sciences, unintended consequences (sometimes unanticipated consequences or unforeseen consequences) are outcomes of a purposeful action that are not intended or foreseen. The term was popularised in the twentieth century by American sociologist Robert K. Merton and expanded by economist Thomas Sowell and psychologist Stuart Vyse.Unintended consequences can be grouped into three types:\n\nUnexpected benefit: A positive unexpected benefit (also referred to as luck, serendipity or a windfall). |
| Exponential growth |
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself. |
| Propagation of uncertainty |
In statistics, propagation of uncertainty (or propagation of error) is the effect of variables' uncertainties (or errors, more specifically random errors) on the uncertainty of a function based on them. When the variables are the values of experimental measurements they have uncertainties due to measurement limitations (e.g., instrument precision) which propagate due to the combination of variables in the function. |
| Measurement uncertainty |
In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity. All measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty, such as the standard deviation. |
| Uncertainty principle |
In quantum mechanics, the uncertainty principle (also known as Heisenberg's uncertainty principle) is any of a variety of mathematical inequalities asserting a fundamental limit to the accuracy with which the values for certain pairs of physical quantities of a particle, such as position, x, and momentum, p, can be predicted from initial conditions.\nSuch variable pairs are known as complementary variables or canonically conjugate variables; and, depending on interpretation, the uncertainty principle limits to what extent such conjugate properties maintain their approximate meaning, as the mathematical framework of quantum physics does not support the notion of simultaneously well-defined conjugate properties expressed by a single value. |
| Policy uncertainty |
Policy uncertainty (also called regime uncertainty) is a class of economic risk where the future path of government policy is uncertain, raising risk premia and leading businesses and individuals to delay spending and investment until this uncertainty has been resolved. Policy uncertainty may refer to uncertainty about monetary or fiscal policy, the tax or regulatory regime, or uncertainty over electoral outcomes that will influence political leadership. |
| Radio regulation |
Radio regulation refers to the regulation and licensing of radio in international law, by individual governments, and by municipalities.\n\n\n== International regulation ==\nThe International Telecommunication Union (ITU) is a specialized agency of the United Nations (UN) that is responsible for issues that concern information and communication technologies. |

A limited liability company (LLC) is the US-specific form of a private limited company. It is a business structure that can combine the pass-through taxation of a partnership or sole proprietorship with the limited liability of a corporation. |
| Liability (financial accounting) |
In financial accounting, a liability is defined as the future sacrifices of economic benefits that the entity is\nobliged to make to other entities as a result of past transactions or other past events, the settlement of which may result in the transfer or use of assets, provision of services or other yielding of economic benefits in the future.\n\n\n== Characteristics ==\nA liability is defined by the following characteristics:\n\nAny type of borrowing from persons or banks for improving a business or personal income that is payable during short or long time;\nA duty or responsibility to others that entails settlement by future transfer or use of assets, provision of services, or other transaction yielding an economic benefit, at a specified or determinable date, on occurrence of a specified event, or on demand;\nA duty or responsibility that obligates the entity to another, leaving it little or no discretion to avoid settlement; and,\nA transaction or event obligating the entity that has already occurredLiabilities in financial accounting need not be legally enforceable; but can be based on equitable obligations or constructive obligations. |

| Monopolistic competition |
Monopolistic competition is a type of imperfect competition such that there are many producers competing against each other, but selling products that are differentiated from one another (e.g. by branding or quality) and hence are not perfect substitutes. |
| Competition (biology) |
Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory). Competition lowers the fitness of both organisms involved, since the presence of one of the organisms always reduces the amount of the resource available to the other.In the study of community ecology, competition within and between members of a species is an important biological interaction. |
| Climbing competition |
A climbing competition (or comp) is usually held indoors on purpose built climbing walls. There are three main types of climbing competition: lead, speed, and bouldering. |
| Drilling rig |
A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers. |
