(Software Engineering) the ability of software to operate in a manner that is secure from internal or external attack
(Environmental Engineering) A surface phenomena in which a solute (soluble material) concentrates or collects at a surface (the adsorbent).
(Environmental Engineering) The consumption of oxygen by the different aquatic organisms as they oxidized materials in the aquatic environment.

(Environmental Engineering) The amount of oxygen required to oxidize any organic matter in the water using harsh chemical conditions.
(english) Inhomogeneous distribution of alloying elements or phases aligned in filaments or plates parallel to the direction of working.
(Environmental Engineering) An illegal and uncontrolled area where wastes have been placed on or in the ground. See Landfill.
(english) A fictitious force used for convenience in visualizing the effects of forces on bodies in motion. For an accelerating body, the inertial force is considered as a body force whose resultant acts at the object's center of gravity in a direction opposite the acceleration. The magnitude of the force is the mass of the object times the magnitude of the acceleration.
(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.
(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.
