Aerodynamics allows the definition and solution of equations for the conservation of mass, momentum, and energy in air.

* not developing eyes allows the individual more energy for growth and reproduction

Since meat has a higher energy density than vegetables, and cooking it allows more nutrients to be liberated to the body, the introduction of cooked meat in the human diet reduced the energy requirements of the digestive system.

The total energy is determined by approximate solutions of the time-dependent Schrödinger equation, usually with no relativistic terms included, and by making use of the Born – Oppenheimer approximation, which allows for the separation of electronic and nuclear motions, thereby simplifying the Schrödinger equation.

All living canids ( Caninae ) have a ligament analogous to the nuchal ligament of ungulates used to maintain the posture of the head and neck with little active muscle exertion ; this ligament allows them to conserve energy while running long distances following scent trails with their nose to the ground.

A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air-fuel mixture due to its higher thermal efficiency.

Chlorophyll is an extremely important biomolecule, critical in photosynthesis, which allows plants to absorb energy from light.

Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light.

This has an important impact on the selectivity of the distillation and allows a chemist to optimize a process such that fewer extremes of pressure and temperature are required and less energy is consumed.

Electron beams are used in welding, which allows energy densities up to across a narrow focus diameter of and usually does not require a filler material.

Phocids produce thick, fat-rich milk that allows them to provide their pups with large amounts of energy in a short period.

To deliver the desired amount of energy, the fuel cells can be combined in series and parallel circuits, where series yields higher voltage, and parallel allows a higher current to be supplied.

The unification of forces is possible due to the energy scale dependence of parameters in quantum field theory called renormalization group running, which allows parameters with vastly different values at collider energies to converge at much higher energy scales.

This design gives additional gas volume, and thereby increased chance of particle interaction, but allows low energy photons to enter the gas through the thin wall.

This temporary measure ( anaerobic metabolism ) allows small amounts of energy to be released.

Once the available energy has been removed, the remaining hot gases are vented ( often by opening a valve or exposing the exhaust outlet ) and this allows the piston to return to its previous position ( top dead center, or TDC ).

This allows electrons to gain energy and thereby move through a conductor such as a metal.

They are well suited to rural life, but their medium energy profile allows them to adjust fairly well to suburban and urban life as well, provided they receive appropriate exercise.

The Phoenix Force allows Jean to revive, absorb, rechannel, and preserve the life-force of any kind of life-form, meaning that she can take life energy from one person and give it to others, heal herself with the same life energy, or even resurrect the dead, since the Phoenix is the sum of all life and death.

A true one-way mirror that actually allows light to be transmitted in one direction only without requiring external energy is not possible as it violates the second law of thermodynamics: if one placed a cold object on the transmitting side and a hot one on the blocked side, radiant energy would be transferred from the cold to the hot object.

Its title describes its contents: it contains the history of Biblical judges, divinely inspired leaders whose direct knowledge of Yahweh allows them to act as champions for the Israelites from oppression by foreign rulers, and models of wise and faithful behaviour required of them by their god Yahweh following the exodus from Egypt and conquest of Canaan.

Some libraries that employ content-control software allow the software to be deactivated on a case-by-case basis on application to a librarian ; libraries that are subject to CIPA are required to have a policy that allows adults to request that the filter be disabled without having to explain the reason for their request.

Digital video also allows footage to be viewed on location without the expensive chemical processing required by film.

Even if the cost of a CPU that has integrated peripherals is slightly more than the cost of a CPU and external peripherals, having fewer chips typically allows a smaller and cheaper circuit board, and reduces the labor required to assemble and test the circuit board.

An augmented system allows a client to prove knowledge of the password to a server, where the server knows only a ( not exactly ) hashed password, and where the unhashed password is required to gain access.

Password aging may be required because of the nature of IT systems the password allows access to ; if personal data is involved the EU Data Protection Directive is in force.

Double action is good for high-stress situations because it allows a mode of carry in which " draw and pull the trigger " is the only requirement — no safety catch release nor separate cocking stroke required.

Liquid sodium is used as a heat transfer fluid in some fast reactors, due to its high thermal conductivity and low neutron absorption cross section, which is required to achieve a high neutron flux ; the high boiling point allows the reactor to operate at ambient pressure.

It also allows for the fixation of the target-probe hybrids, required for analysis by autoradiography or other detection methods.

Since the vocoder process sends only the parameters of the vocal model over the communication link, instead of a point by point recreation of the waveform, it allows a significant reduction in the bandwidth required to transmit speech.

This allows the Paladin to halt from the move and fire within 30 seconds with accuracy equivalent to the previous models when properly emplaced, laid, and safed — a process that required several minutes under the best of circumstances.

Some groups that propose sexual abstinence consider it an essential means to reach a particular intellectual or spiritual condition, or that chastity allows one to achieve a required self-control or self-consciousness.

This synchronization system allows entire inter-country networks to operate synchronously, greatly reducing the amount of buffering required between elements in the network.

Due to conservation of energy, the same amount of mechanical energy ( work ) is required to lift a given object by a given vertical distance, disregarding losses from friction, but the inclined plane allows the same work to be done with a smaller force exerted over a greater distance.

This equation allows operators to determine whether each of their circuit groups meet the required Grade of Service, simply by monitoring the reference traffic intensity.

In telecommunication, a technical control facility ( TCF ) is a telecommunications facility, or a designated and specially configured part thereof, that ( a ) contains the equipment necessary for ensuring fast, reliable, and secure exchange of information, ( b ) typically includes distribution frames and associated panels, jacks, and switches and monitoring, test, conditioning, and orderwire equipment, and ( c ) allows telecommunications systems control personnel to exercise operational control of communications paths and facilities, make quality analyses of communications and communications channels, monitor operations and maintenance functions, recognize and correct deteriorating conditions, restore disrupted communications, provide requested on-call circuits, and take or direct such actions as may be required and practical to provide effective telecommunications services.

The key advantage of VHDL, when used for systems design, is that it allows the behavior of the required system to be described ( modeled ) and verified ( simulated ) before synthesis tools translate the design into real hardware ( gates and wires ).

It allows 324 minutes to be recorded on an 80 minute MiniDisc, with the same padding required as LP2.

In these applications thin films of ferroelectric materials are typically used, as this allows the field required to switch the polarization to be achieved with a moderate voltage.

But, if the question is inherently required by the concept of omnipotence, then it seems the logic which allows it to be inherently required is a paradox since the particular concept of omnipotence which requires it is a paradox.

When an aircraft's lift is less than what is required for it to continue flying and stalls, ideally the nose should drop, which allows the aircraft to regain flying speed.

The aperture is proportional to the square root of the light admitted, and thus inversely proportional to the square root of required exposure time, such that an aperture of 2 allows for exposure times one quarter that of 4.
