The Bottom Line: What You Really Need to Know. 1  Trazodone (Trade Names: Deseryl) is an antidepressant with many other uses.  The usual dose depends on what it is being taken for and can range from 150-600 mg/day.
Figure 1. An XKCD comic showing the comparative energy density of Uranium. Energy density is the amount of energy that can be stored in a given mass of a substance or system. The higher the energy density of a system or material, the greater the amount of energy stored in its mass. Energy can be stored in many different types of substances and systems. A material can release energy in four types of reactions.
The number of states per unit volume is. The final density of states as a function of energy is then the deriviative of this population with respect to energy. This represents the number of photons per unit volume per unit energy at energy E. This energy density is a factor in thermal radiation from a cavity.
