The second and third lines of defense operate by making changes to the buffers, each of which consists of two components: a weak acid and its conjugate base. [ 5 ] [ 13 ] It is the ratio concentration of the weak acid to its conjugate base that determines the pH of the solution. [ 14 ]

Artillery barrage: a line or barrier of exploding artillery shells, created by continuous and co-ordinated fire of a large number of guns. Battalia : an army or a subcomponent of an army such as a battalion in battle array (common military parlance in the 17th century).
Blue line Chromate and dichromate have equal concentrations. Setting [CrO 2− 4] equal to [Cr 2 O 2− 7] in Eq. 3 gives [CrO 2− 4] = 1 / β 2 [H +] 2 . The predominance diagram is interpreted as follows. The chromate ion is the predominant species in the region to the right of the green and blue lines. Above pH ~6.75 it is always the ...
Deliberate risk management is used at routine periods through the implementation of a project or process. Examples include quality assurance, on-the-job training, safety briefs, performance reviews, and safety checks.

Defence in depth (also known as deep defence or elastic defence) is a military strategy that seeks to delay rather than prevent the advance of an attacker, buying time and causing additional casualties by yielding space. Rather than defeating an attacker with a single, strong defensive line, defence in depth relies on the tendency of an attack ...
Chemical defense is a strategy employed by many organisms to avoid consumption by producing toxic or repellent metabolites or chemical warnings which incite defensive behavioral changes. [ 1 ] [ 2 ] The production of defensive chemicals occurs in plants, fungi, and bacteria, as well as invertebrate and vertebrate animals.
