A dam is a structure built across a stream or river to hold water back. Dams can be used to store water, control flooding, and generate electricity.
In neurogenic shock, the characteristic mechanism is the reduction of sympathetic outflow from the brainstem leading to the decreased in the blood vessel tone and eventually vasodilation. In the presence of vasodilation, there will be decreased blood pressure and eventually shock. Since there is reduced sympathetic outflow, there will also be a decreased heart rate, warm skin (from the vasodilation), and dry skin (from the reduced cholinergic stimulation of the sweat glands).
Kites most likely spent the majority of the time active perching because they were actively looking for prey from an arial angle which allowed them to scope out their next victim
We find significant soil pH neutralization by afforestation—afforestation lowers pH in relatively alkaline soil but raises pH in relatively acid soil.
