Sentences with phrase «measure electrical fields»

«With the Institute for Glycomics I'm also interested in developing this into a tool to measure the electrical fields outside a single isolated biomolecule, like the dipole moment, as a new way to help understand how they behave,» he said.

In the new work, published June 10 in the journal Scientific Reports, Zhao, Reid and colleagues used a highly sensitive probe to measure electrical fields in the corneas of isolated eyes from three different lab mouse models with different types of diabetes: genetic, drug - induced and in mice fed a high - fat diet.

Not exact matches

Also there is evidence of molecular mechanisms in the cell membranes that can amplify small changes in the field to produce large changes in neural activity.13 On the other hand, earlier tests of Kohler's theory found that interference with electrical gradients over the cortex had no effect on behavioral measures (see note 11 for reference to these studies).

Thanks to Swarm's precise measurements along with those from Champ — a mission that ended in 2010 after measuring Earth's gravity and magnetic fields for more than 10 years — scientists have not only been able to find the magnetic field generated by ocean tides but, remarkably, they have used this new information to image the electrical nature of Earth's upper mantle 250 km below the ocean floor.

Structural magnetic resonance imaging (MRI), which measures the anatomy and structural integrity of the brain, and magnetoencephalography (MEG), which measures magnetic fields created by the brain's electrical activity, were used to track potential age - related differences as groups of younger and older adults performed a memory task.

Electrical sensors measure both the angle and the force applied by the user on the ankle, and a computer modifies the strength of the magnetic field accordingly.

In a performance check, the scientists measured the amount of electrical current running through the films in low and high magnetic fields.

Electrical conductivity, a measure of how strongly a given material conducts the flow of electric current, is generally understood in terms of Ohm's law, which states that the conductivity is independent of the magnitude of an applied electric field, i.e. the voltage per metre.

«The equipment currently used to measure electric field strength has some significant downsides,» explains Andreas Kainz from the Institute of Sensor and Actuator Systems (Faculty of Electrical Engineering, TU Wien).

Gow's method of investigating how the human brain perceives and distinguishes among elements of spoken language combines electroencephalography (EEG), which records electrical brain activity; magnetoencephalograohy (MEG), which the measures subtle magnetic fields produced by brain activity, and magnetic resonance imaging (MRI), which reveals brain structure.

This law is widely obeyed in weak applied fields, which means that most material samples can be ascribed a definite electrical resistance, measured in Ohms.

«When electrical currents are created in such a system of flows, they can cause a magnetic field which in turn increases the electrical current and so forth — and finally the magnetic field becomes so strong that we can measure it on the surface of Earth,» says Alessandro Toschi.
