Targeting time period

As it can be inferred from Fig. 12.6, in the time period (0-0.5 h), 40 t of water is available for reuse. In the time period (0.5-1.0 h), 501 of water is required, but there is only 37.5 t of water available. Therefore, 12.5 t of water is required from storage. In the time period (1.0-1.5 h), 50 t of water is required and only 25 t is available, thus 25 t of water is required from storage. This implies that 37.5 t of water from time period (0-0.5 h) should be stored for reuse in the time periods (0.5-1.0 h) and (1.0-1.5 h). Figure 12.7 shows the design to meet the target. 

In practice, if a manufacturer is the target, the government will likely attempt to develop evidence by subpoena of persons and materials which will help prove culpability. It is likely the subpoenas will ask for correspondence, notes, and memos during a particular time period and involving a particular subject matter. 

Intravenous injection is the quickest common pathway to introducing a drug and having it reach its target within an extremely short time period. This relates to the "rush" of drug effects experienced by i.v. drug abusers. It is valuable for emergency use but unwanted side effects may also be intensified. 

During early fetal development, there are critical or sensitive periods when malformations are most likely to be induced. These critical periods are short windows of time during the phase of organogenesis. Teratological calendars have been drawn up for humans, laboratory animals, and target animals identifying the critical time periods. 

Denaturation. The reaction mixture is heated to 95°C for a short time period (about 15-30 sec) to denature the target DNA into single strands that can act as templates for DNA synthesis.
