Fluorinated gasesFluorinated gases (F-gases) are chemical compounds containing fluorine that are gases near room temperature. The most common F-gases are hydrofluorocarbons (HFCs), which contain hydrogen, fluorine, and carbon. They are used in a multitude of applications including commercial refrigeration, industrial refrigeration, air-conditioning systems, heat pump equipment, and as blowing agents for foams, fire extinguishants, aerosol propellants, and solvents. HFC-134a (1,1,1,2-Tetrafluoroethane) has grown to become the most abundant HFC in earth's atmosphere as of year 2015.
Nationally determined contributionA nationally determined contribution (NDC) or intended nationally determined contribution (INDC) is a non-binding national plan highlighting climate change mitigation, including climate-related targets for greenhouse gas emission reductions. These plans also include policies and measures governments aim to implement in response to climate change and as a contribution to achieve the global targets set out in the Paris Agreement. NDCs are the first greenhouse gas targets under the UNFCCC that apply equally to both developed and developing countries.
Great LakesThe Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the east-central interior of North America that connect to the Atlantic Ocean via the Saint Lawrence River. The five lakes are Superior, Michigan, Huron, Erie, and Ontario and they are in general on or near the Canada–United States border. Hydrologically, Michigan and Huron are a single body of water joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes.
Convective inhibitionConvective inhibition (CIN or CINH) is a numerical measure in meteorology that indicates the amount of energy that will prevent an air parcel from rising from the surface to the level of free convection. CIN is the amount of energy required to overcome the negatively buoyant energy the environment exerts on an air parcel. In most cases, when CIN exists, it covers a layer from the ground to the level of free convection (LFC).
Territorial watersTerritorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf. In a narrower sense, the term is often used as a synonym for the territorial sea. Vessels have different rights and duties when passing through each area defined by the United Nations Convention on the Law of the Sea (UNCLOS), one of the most ratified treaties.
Genesis creation narrativeThe Genesis creation narrative is the creation myth of both Judaism and Christianity. The narrative is made up of two stories, roughly equivalent to the first two chapters of the Book of Genesis. In the first, Elohim (the Hebrew generic word for god) creates the heavens and the Earth in six days, then rests on, blesses, and sanctifies the seventh (i.e. the Biblical Sabbath). In the second story God (now referred to by the personal name Yahweh) creates Adam, the first man, from dust and places him in the Garden of Eden.
Genesis RabbahGenesis Rabbah (Hebrew: , B'reshith Rabba) is a religious text from Judaism's classical period, probably written between 300 and 500 CE with some later additions. It is a midrash comprising a collection of ancient rabbinical homiletical interpretations of the Book of Genesis (B'reshith in Hebrew). It is expository midrash to the first book of the Torah, assigned by tradition to the amora Hoshaiah (or Osha'yah), who flourished in the third century in Roman Syria Palaestina.
Topic-prominent languageA topic-prominent language is a language that organizes its syntax to emphasize the topic–comment structure of the sentence. The term is best known in American linguistics from Charles N. Li and Sandra Thompson, who distinguished topic-prominent languages, such as Korean and Japanese, from subject-prominent languages, such as English. In Li and Thompson's (1976) view, topic-prominent languages have morphology or syntax that highlights the distinction between the topic and the comment (what is said about the topic).
PostconditionIn computer programming, a postcondition is a condition or predicate that must always be true just after the execution of some section of code or after an operation in a formal specification. Postconditions are sometimes tested using assertions within the code itself. Often, postconditions are simply included in the documentation of the affected section of code. For example: The result of a factorial is always an integer and greater than or equal to 1.
Salt miningSalt mining extracts natural salt deposits from underground. The mined salt is usually in the form of halite (commonly known as rock salt), and extracted from evaporite formations. Before the advent of the modern internal combustion engine and earth-moving equipment, mining salt was one of the most expensive and dangerous of operations because of rapid dehydration caused by constant contact with the salt (both in the mine passages and scattered in the air as salt dust) and of other problems caused by accidental excessive sodium intake.
