For instance, if a transmitter delivers 100 W into an antenna having an efficiency of 80%, then the antenna will radiate 80 W as radio waves and produce 20 W of heat. In order to radiate 100 W of power, one would need to use a transmitter capable of supplying 125 W to the antenna. Note that antenna efficiency is a separate issue from impedance matching, which may also reduce the amount of power radiated using a given transmitter. If an SWR meter reads 150 W of incident power and 50 W of reflected power, that means that 100 W have actually been absorbed by the antenna (ignoring transmission line losses). How much of that power has actually been radiated cannot be directly determined through electrical measurements at (or before) the antenna terminals, but would require (for instance) careful measurement of field strength. Fortunately the loss resistance of antenna conductors such as aluminum rods can be calculated and the efficiency of an antenna using such materials predicted.
What would need to be investigated to determine how much power was radiated?
electrical measurements

Humanitarian Assistance Operations are "programs conducted to relieve or reduce the results of natural or manmade disasters or other endemic conditions such as human pain, disease, hunger, or privation that might present a serious threat to life or that can result in great damage to or loss of property. Humanitarian assistance provided by US forces is limited in scope and duration. The assistance provided is designed to supplement or complement the efforts of the host nation civil authorities or agencies that may have the primary responsibility for providing humanitarian assistance" (JP 1-02).
What kinds of endemic conditions do the Human Assistance Operations entail?
human pain, disease, hunger, or privation that might present a serious threat to life

The "No Surprises" rule is meant to protect the landowner if "unforeseen circumstances" occur which make the landowner's efforts to prevent or mitigate harm to the species fall short. The "No Surprises" policy may be the most controversial of the recent reforms of the law, because once an Incidental Take Permit is granted, the Fish and Wildlife Service (FWS) loses much ability to further protect a species if the mitigation measures by the landowner prove insufficient. The landowner or permittee would not be required to set aside additional land or pay more in conservation money. The federal government would have to pay for additional protection measures.
Why is this particular rule so controversial?
the Fish and Wildlife Service (FWS) loses much ability to further protect a species if the mitigation measures by the landowner prove insufficient.
