Tertiary prevention strategies are interventions that are designed to meet the longterm needs of individuals and the community after the disaster has been resolved. The required types and scope of tertiary services will largely be determined by the type and scope of the disaster.

Alcohols can also be categorised as primary (1º), secondary (2º) or tertiary depending on the number of carbon atoms that are attached to the carbon atom holding the OH group. For example: propan1ol is a primary alcohol, while propan2ol is a secondary alcohol. .

Sep 13, 2018· Primary, secondary, tertiary, and quaternary are the four structures of proteins found in nature. The primary structure comprises the amino acid sequence. Hydrogen bonds formed between amino acids are responsible for the formation of the secondary structure of a protein while disulfide and salt bridges form the tertiary structure.
