Direct paragraph, definition

As mentioned in paragraph 11.6.1 bioceramics are used to repair defects in the human body. Thus a material from outside the body is brought into direct contact with body tissue without any intermediate layer like the skin. These materials are called implants or biomaterials and can be defined in several ways. Two of these definitions are ... 

Irreversible electrode phenomena polarization and over-potential. Most of the electrode reactions mentioned in the preceding paragraph are nearly reversible that is, the electrode when dipped into the electrolyte immediately assumes a definite potential difference from the solution, which is but slightly affected by small currents passing across the electrode. Should the potential of the electrode be raised slightly above the equilibrium reversible value, the current flows from the electrode to the solution if the potential falls slightly, the current flows in the opposite direction. For a perfectly reversible electrode, an infinitesimal departure of the potential from the equilibrium value should cause a considerable current to flow in one or the other direction. 

This definition is contained in paragraph 1 of Article II. It covers toxic and precursor chemicals (paragraph 1(a)), munitions and devices specifically designed for chemical weapons purposes (paragraph 1(b)), and any equipment specifically designed for direct use in the employment of such munitions and devices (paragraph 1(c)). The term applies to them together or separately. 

The conclusions arrived at in this paragraph are all of course a direct consequence of the definition of ideal systems in which [jl, etc. are not necessarily identified with the corresponding quantities for the pure components. 

In the Council Directive 91/689/EEC of 12 December 1991 on hazardous wastes [12], Article 1, Paragraph 4, hazardous waste is classified in a similar way to that in the Basel Convention [10], The definition of the H14 criterion of ecotoxicity is not, however, as comprehensive as criterion H12 in the Basel Convention [10]. 

In Sect. 2.2 the half essentially disconnected (HED) single coronoids are defined (provisionally) as the normal single coronoid which are not regular. A direct definition of the HED single coronoids, compatible with the provisional definition of Sect. 2.2, is furnished through the theorem of the next paragraph.
