The energy released in this transition may be emitted as a photon ( spontaneous emission ), however in practice the 3 → 2 transition ( labeled R in the diagram ) is usually radiationless, with the energy being transferred to vibrational motion ( heat ) of the host material surrounding the atoms, without the generation of a photon.

Energy and torque are entirely different concepts, so the practice of using different unit names ( i. e., reserving newton metres for torque and using only joules for energy ) helps avoid mistakes and misunderstandings.

Typical fuel pellets are about the size of a pinhead and contain around 10 milligrams of fuel: in practice, only a small proportion of this fuel will undergo fusion, but if all this fuel were consumed it would release the energy equivalent to burning a barrel of oil.

Any modulated signal will have an infinite number of sidebands and hence an infinite bandwidth but in practice all significant sideband energy ( 98 % or more ) is concentrated within the bandwidth defined by Carson's rule.

The spin from rifling decreases the effective penetration of these rounds ( rifling diverts some of the linear kinetic energy to rotational kinetic energy, thus decreasing the round's velocity and impact energy ) and so they are generally fired from smoothbore guns ; a practice that has been taken up by Israel — a major supplier of " arrow " rounds — China, France, Pakistan, Germany, Russia, and the United States in their tanks.

As a word of caution, we should be aware that in actual practice no message is purely one of the four types, question, command, statement, or exclamation.

This condition will undoubtedly continue until such time as a state uniform system of evaluation is established, or through mutual agreement of the local assessing officials for a method of standard assessment practice to be adopted.

To summarize, it may be said that there is no one prevailing practice in Rhode Island with respect to the taxation of movable property, that assessors would like to see an improvement, and of those who have an opinion, that assessment by the town of location is preferred on the basis of their present knowledge.

It is the classroom teacher, however, who has daily contacts with pupils, and who is in a unique position to put sound psychological principles into practice.

But the really controversial aspect of customer-cost imputation arises because of the cost analyst's frequent practice of including, not just those costs that can be definitely earmarked as incurred for the benefit of specific customers but also a substantial fraction of the annual maintenance and capital costs of the secondary ( low-voltage ) distribution system -- a fraction equal to the estimated annual costs of a hypothetical system of minimum capacity.
