They are powered by hydrogen fuel or solar cells, batteries and ultracapacitors.

Sinautec is in discussions with MIT's Schindall about developing ultracapacitors of higher energy density using vertically aligned carbon nanotube structures that give the devices more surface area for holding a charge.

So in vehicles that have to stop frequently and predictably as part of normal operation, energy storage based exclusively on ultracapacitors begins to make sense.

It is believed that graphene could be used to produce ultracapacitors with a greater energy storage density than is currently available.

The best ultracapacitors can only store about 5 percent of the energy that lithium-ion batteries hold, limiting them to a couple of miles per charge.

Another 60 buses will be delivered early next year with ultracapacitors that supply 10 watt-hours per kilogram.

The turbine can be run at optimum speed for its power output, and batteries and ultracapacitors can supply power as needed, with the engine cycled on and off to run it only at high efficiency.

* The method for store ( batteries, ultracapacitors ) or collecting ( transmission ) electrical power.

* Paris: RATP is using a hybrid electric bus outfitted with ultracapacitors ; the model used is the MAN Lion's City Hybrid.

Due to the extremely high surface area to mass ratio of graphene, one potential application is in the conductive plates of ultracapacitors.

An electric aircraft runs on electric motors rather than internal combustion engines, with electricity coming from fuel cells, solar cells, ultracapacitors, power beaming, or batteries.

The size of commercially available capacitors ranges from around 100 fF ( femtofarads, 10 < sup >- 15 </ sup > F ) to 5 kF ( kilofarads, 10 < sup > 3 </ sup > F ) ultracapacitors.

But what ultracapacitors lack in range they make up in their ability to rapidly charge and discharge.

`` I made you what you are '', Gavin whispered.

If it were not for an old professor who made me read the classics I would have been stymied on what to do, and now I understand why they are classics ; ;

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

But people can't be made to integrate, socialize ( the two are inseparable by Southern standards ) by law.

Since the hazards of poor communication are so great, p can be justified as a habitable site only on the basis of unusual productivity such as is made available by a waterfall for milling purposes, a mine, or a sugar maple camp.

( C ) Decisions of a general kind are made by the central command.

As a creative enterprise, its abilities are primarily in `` swallowing '' creative enterprises developed outside its own organization ( an ability made possible by us, and almost mandatory ).

Some years ago Julian Huxley proposed to an audience made up of members of the British Association for the Advancement of Science that `` man's supernormal or extra-sensory faculties are ( now ) in the same case as were his mathematical faculties during the ice age ''.

On December 21, the day that the Irish House of Commons petitioned for removal of Sir Constantine Phipps, their Tory Lord Chancellor, Molesworth reportedly made this remark on the defense of Phipps by Convocation: `` They that have turned the world upside down, are come hither also ''.

Since the recognition of Israel as a nation state, claims are made in many cases which identify the claimant as a member of the new body politic.

As more men and women are made capable of living up to the challenge of decency the chances are improved that the pattern of predisposition prevailing in positions of strength in future crises can be favorably affected.

At least I should like them to know that I know these discounts are being made.

Even with all possible precaution, homecomings are usually rather cruel and sad, and only the perpetually ebullient and the continually optimistic are made happy by them.

Sir -- We are writing in reference to a recent `` suggestion '' made to the staff of the Public Health Nursing Service of Jersey City ( registered professional nurses with college background and varying experiences ).

It will determine the amount of money to be spent by the college and will certify this amount to the board of freeholders, which `` shall appropriate in the same manner as other appropriations are made by it the amount so certified and the amount shall be assessed, levied and collected in the same manner as moneys appropriated for other purposes ''.

`` See, Argiento, if you control the way these folds are bunched, like this, or made to flow, you can enrich the body attitudes.

SBA loans, which may be made to small manufacturers, small business pools, wholesalers, retailers, service establishments and other small businesses ( when financing is not otherwise available to them on reasonable terms ), are to finance business construction, conversion, or expansion ; ;

Participation loans are those made jointly by the SBA and banks or other private lending institutions.

Direct loans are those made by SBA alone.

Three distinct classes of loans are made available to farmers' cooperatives by the Banks for Cooperatives: Commodity loans, operating capital loans, and facility loans.

Once we have made clear that we are genuinely concerned with a country's development potential, we can be blunt in suggesting the technical conditions that must be met for development to occur.

Requests are made by the motor pool along with any necessary cooperation from the agencies to which assignments of cars will be made.

Once trained and forgotten, completed habits may be activated without feedback sensations that these habits are in effect, just by thinking about them.

Control of proapoptotic proteins under normal cell conditions of nonapoptotic cells is incompletely understood, but in general, Bax or Bak are activated by the activation of BH3-only proteins, part of the Bcl-2 family.

Effector caspases are then activated by these active initiator caspases through proteolytic cleavage.

Adenylate cyclases are often activated or inhibited by G proteins, which are coupled to membrane receptors and thus can respond to hormonal or other stimuli.

This is supported by the fact that adenylate cyclases are coincidence detectors, meaning that they are activated only by several different signals occurring together.

Precatalysts are easier to store but are easily activated in situ.

Supports are porous materials with a high surface area, most commonly alumina or various kinds of activated carbon.

In some areas, ( such as California and Kansas ) registered, activated CERT members are eligible for worker's compensation for on-the-job injuries during declared disasters.

The signals from these receptors are transmitted across the plasma membrane into the cytosol, where Che proteins are activated.

Due to widespread cable theft in earlier analog systems, in modern digital cable systems the signals are encrypted, and the set-top box must be activated by an activation code sent by the cable company before it will function, which is only sent after the subscriber signs up.

Hippocampal cells ( neurons ) are activated depending on what information one is exposed to at that moment.

There are several methods by which an automatically opening door is activated:

All FARG computational models share certain key principles, among which are: that human thinking is carried out by thousands of independent small actions in parallel, biased by the concepts that are currently activated ; that activation spreads from activated concepts to less activated " neighbor concepts "; that there is a " mental temperature " that regulates the degree of randomness in the parallel activity ; that promising avenues tend to be explored more rapidly than unpromising ones.

Knights cannot perform actions on the same turn they are activated, but can be reactivated on the same turn as performing an action.

This would be player B, but the same applies for him: he has activated only 1 knight, but both of his cities are metropolises.

Such EC " direction " path cells show this directional activity irrespective of the location of where a person experiences themselves, which contrasts them to place cells in the hippocampus, which are activated by specific locations.
