2. Among these is the major BGS-led joint European study of the southern North Sea Quaternary succession.
3. Accordingly, in this section we shall expand the three levels of prevention to four, that is, primary, secondary, tertiary, and quaternary.

The company was worked consistently over the years to develop special knowledge and expertise in particular areas e.g. chiral compounds and building blocks; quaternary ammonium compounds for phase transfer catalysis and electrochemistry; silylating agents; a range of products for ion-selective electrode work and a comprehensive range of highly purified reagents for bio-chemistry marked under trade name Micro-Select .
8. Thus treatment with salt (or with freshwater for marine fish), formalin, quaternary ammonium compounds, malachite green, and antibiotics for example can be given at high dose for short duration, making them more effective against the disease organisms while offering a better safety margin to the fish through shorter contact time.
