111Turbulence — In fluid dynamics, turbulence or turbulent flow is a fluid regime characterized by chaotic, stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and… …
112Mesoscale convective system — A shelf cloud such as this one can be a sign that a squall is imminent A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical… …

114Space Shuttle external tank — A Space Shuttle External Tank (ET) is the component of the Space Shuttle launch vehicle that contains the liquid hydrogen fuel and liquid oxygen oxidizer. During lift off and ascent it supplies the fuel and oxidizer under pressure to the three… …
115Lean burn — refers to the use of lean mixtures in an internal combustion engine. The air fuel ratios can be as high as 65:1, so the mixture has considerably less fuel in comparison to the stoichiometric combustion ratio (14.7:1 for petrol for example).… …
116Meander — For other uses, see Meander (disambiguation). A hypothetical stream bed following a tilted valley. The maximum gradient is along the down valley axis represented by a hypothetical straight channel. Meanders develop, which lengthen the course of… …

118building construction — Techniques and industry involved in the assembly and erection of structures. Early humans built primarily for shelter, using simple methods. Building materials came from the land, and fabrication was dictated by the limits of the materials and… …
119Membraneless Fuel Cells — convert stored chemical energy into electrical energy without the use of a conducting membrane as with other types of fuel cells. In Laminar Flow Fuel Cells (LFFC) this is achieved by exploiting the phenomenon of non mixing laminar flows where… …
120Superconductivity — is a phenomenon occurring in certain materials generally at very low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect).The electrical resistivity of a metallic …
