Answer:
ABAB design
Explanation:
This method used in the field of research on Behavior Modification consists of four phases:
1. Phase A: Stable patient.
2. Phase B: Introduction of treatment.
3. Second Phase A: Withdrawal of treatment before consolidation.
4. Second Phase B: Reintroduction of treatment
This allows to verify the reliability of the change produced by the treatment. If it produces a new behavior change, we would have more evidence that the cause of the change is treatment.
Answer:
Both technicians A and B are correct
Explanation:
A pump check valve is device that allows the flow of any fluid in only one direction and prevents the flow from the reverse direction.
When the pump operates, there is pressure that develops inside the pump. Now when the pump is shut down, the pump check valve is able to hold the pump pressure for sometimes until the pressure inside the pump becomes normal.
When the pump check valve is defective, there is a drop in pressure inside the regulator or the pump. Because of the drop in pressure, it takes long time for the pump to start and hence longer cranking time.
Thus both technician A and technician B is correct.
Hence the answer is ---
Both technicians A and B are correct

The final treatment of wastewater in the united states normally involves treatment with Chlorine to make it safe.
The final stage of the wastewater treatment process, which is when it is often carried out in most treatment plants, can also include chlorination. The primary goals of this chlorine addition are water disinfection and maintaining chlorine residuals that will stay in the water as it moves through the distribution system.
In the US, wastewater treatment facilities treat over 34 billion gallons of wastewater per day. Human waste, food waste, and some soaps and detergents all contribute nitrogen and phosphorus to wastewater. Once the water has been cleansed to the standards required and observed by state and federal authorities, it is often released into a nearby water body.
