Tennessee Valley Authority civil engineers monitoring hydraulics of a scale model of Tellico Dam. Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings ...
In an interview shortly after the publication of the 1978 paper, Gabbard coined the term Kessler syndrome to refer to the accumulation of debris; [4] it became widely used after its appearance in a 1982 Popular Science article, [10] which won the Aviation-Space Writers Association 1982 National Journalism Award.

The Kiribati Adaptation Program (KAP) is a US$5.5 million initiative that was originally enacted by the national government of Kiribati with the support of the Global Environment Facility (GEF), the World Bank, the United Nations Development Program, and the Japanese Government. Australia later joined the coalition, donating US$1.5 million to ...
The Lee–Kesler method [1] allows the estimation of the saturated vapor pressure at a given temperature for all components for which the critical pressure P c, the critical temperature T c, and the acentric factor ω are known.
Adaptive control is the control method used by a controller which must adapt to a controlled system with parameters which vary, or are initially uncertain. [1] [2] For example, as an aircraft flies, its mass will slowly decrease as a result of fuel consumption; a control law is needed that adapts itself to such changing conditions.
Climate adaptation planning aims to manage the level of risks of negative impacts. Adaptation planning is similar to risk management. It is a continuing process of assessment, action, learning and adjustment, rather than a single set of decisions. In this way planning and implementing adaptation are both closely connected.

[5] [1] The report was delivered in stages, starting with the report from Working Group I in September 2013. [5] It reported on the physical science basis, based on 9,200 peer-reviewed studies. [ 6 ] [ 7 ] The Synthesis Report was released on 2 November 2014, [ 8 ] in time to pave the way for negotiations on reducing carbon emissions at the UN ...
They considered the possibility that these abilities resulted from an evolutionary genetic adaptation to high-altitude conditions. [31] The Tibetan plateau has an average elevation of 4,000 meters (13,000 ft) above sea level and covers more than 2.5 million km 2; it is the highest and largest plateau in the world. In 1990, it was estimated that ...
