Those technologies include the «driver» used to crush the fuel capsule, such as lasers, heavy ion beams, or powerful
pulses of electric current.
Using electrical measurements he collected during the eel attacks, Catania came up with an equation to estimate the amount
of electric current flowing from the eel into his arm.
Cluster pioneered measurements
of electric currents in space, revealed the nature of black aurorae, and discovered that plasma — a gas of charged particles surrounding Earth — makes «waves».
Scientists simply input two parameters into the equation: separation distance, and certain material properties of each object — namely, the maximum
amount of electric current that can build up in a given material.
But the definition of one fundamental physical quantity — the ampere, the
unit of electric current — falls somewhat short of that ideal.
In three randomized trials, treatment of chronic low back pain with radiofrequency denervation, a procedure that can be performed with different techniques including the
application of an electric current to the pain - conducting nerve, resulted in either no improvement or no clinically important improvement in chronic low back pain, according to a study published by JAMA.
When he and his team replaced the light - sensitive components of a solar cell with a very thin layer of the perovskite, the illuminated cell pumped out a little
bit of electric current.
Scientists at PPPL have produced self - consistent computer simulations that capture the
evolution of an electric current inside fusion plasma without using a central electromagnet, or solenoid.
Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have produced self - consistent computer simulations that capture the evolution
of an electric current inside fusion plasma without using a central electromagnet, or solenoid.
VORTEX FOUND Newly observed
swirls of electric current in a high - temperature superconductor (shown in an artist's conception) may indicate that the unusual material fits within the standard theoretical picture.
When placed in a magnetic field, many superconductors display swirling
vortices of electric current — a hallmark of the standard superconductivity theory.
This compound mediates the transfer of electrons from the biological membranes to the electrical circuit, enabling the
creation of an electric current in the cell.
Superconducting materials exhibit an invaluable feature when cooled below a critical temperature — they allow the
transport of an electric current without loss.
How would Michael Faraday have described his «project»: «To conduct a series of experiments with the purpose of discovering the
induction of an electric current»?
When sunshine strikes a solar cell, some of the electrons in the cell take on energy but quickly lose most of it as thermal energy rather than breaking loose to become
part of an electric current.
Otto Overbeck claimed to have the answer: wire yourself up to his «Rejuvenator», plug in the battery and enjoy the scintillating
buzz of an electric current that slowly restores your body's youthful vigour.
Summers underwent regular physical therapy sessions during which researchers passed pulses
of electric current through the electrodes to stimulate neurons in the spinal cord.
When hooked up to an electronic sensor, the pad converts signals from the sensor into small pulses
of electric current across the grid, which the tongue «reads» as a pattern of tingles.
When one attempts to recharge a battery by reversing the
direction of electric current flow, the opposite takes place: a reduction reaction proceeds at the negative electrode, and an oxidation reaction takes place at the positive electrode.
The team also found the moment of conversion resulted in a sudden
reduction of electric current, suggesting diamene could have interesting electronic and spintronic properties.
The turbulence was uncovered using just two of the four Cluster satellites and showed for the first time that the solar wind plasma is extremely structured at this high resolution with turbulent swirls bordered by a
sheet of electric current just 20 kilometres across.
Based on the fact that nothing can grab hold of your attention as effectively as an electric shock, Pavlok have created the first «behavior change wearable» that will jolt you with 340
V of electric current whenever you choose not to follow your fitness plan (or any other plan, for that matter).
But it quickly becomes apparent that director Alfonso Gomez - Rejon has no idea what to do with the true story of Thomas Edison versus George Westinghouse and their fight to bring their respective
systems of electric current to the U.S.. It's a movie that has a clear conflict but couldn't find a theme with two hands a flashlight.
Each time a network is activated — the information recalled for review or use — the connections become stronger and faster (speed through a circuit is largely determined by the layers of myelin coating that are built up around the axons — this is also in response to the flow
of the electric current of information transport when the circuit is activated).
Brake Energy Regeneration, which is also a standard feature, ensures that the
generation of electric current for the onboard electrical systems concentrates on the overrun and braking phases.
The idea that animal's bodies were
vessels of electric current — and that dead animal tissue might be brought back to life if the electrical charge could be restored (think of it like jump - starting a car battery)-- caught the imagination of the scientific community, as well as the public.
E Ink's approach differed from Gyricon in that
instead of the electric current rotating individual color spheres in a film, the change in the electric charge would rotate small color particles within each sphere, allowing for more refined images and better grayscale.
It's the first time this room - sized installation — in which lightbulbs flash on and off inside a grid of wire - mesh cages, to the amplified
whine of the electric current — has been shown in Europe.
17 December 2010 — 6 March 2011 Gallery 7 Current Disturbance is a room - filling environment made from stacked wire cages, light bulbs and the amplified
sound of electric currents.
The
frequency of electric current in the United States is supposed to be stable at 60 cycles a second, but if the supply from a wind farm or solar plant changes suddenly, or demand shifts, frequency gets out of whack.
But most importantly, plasma double layers only appear when there is an electric current flow between objects — electrically inert objects don't seem to develop plasma double layers, so this means that when a plasma DL is observed, then its a
effect of an electric current between two objects.
