All the elements required for topological currents are present in neutron stars: de-generate matter, large magnetic elds, and parity violating processes. These conditions lead to the creation of vector currents capable of carrying momentum and inducing mag-netic elds. We estimate the size of these currents for many representative states of dense

Ocean Surface Currents . The water at the ocean surface is moved primarily by . winds that blow in certain patterns because of the Earth’s spin and the Coriolis Effect. Winds are able to move the top 400 meters of the ocean creating surface ocean currents. Surface ocean currents form larg

2. Eddy currents Tuned Mass Damper When a conductive material moves along a stationary magnetic field, eddy currents are induced, (Figure 1.a). By neglecting the surface charge in the conductive plate, the eddy currents density can be written as: J v B uV() (1) where V is the electrical conductivity of the conductive material, ()T v vz is the .

from that hemisphere to the northern by ocean-currents. Croll's arguments for how currents accomplish this transport was stated as follows: Since there is a constant flow of water from the southern hemisphere to the northern in the form of surface currents, it must be compensated by under-currents of equal magnitude from the northern

Waves - Waves continually deposit and remove sediments from the ocean side of the island. Currents - Longshore currents that are caused by waves hitting the island at an angle can move the sand from one end of the island to another. For example, the offshore currents along the east coast

Fixing p(o) of these currents all hinders the slow diastolic depolarization, but the effects are rather small if compared to that of I Kr in these three models. In this respect, these currents might be categorized as “supplemental”currents.Namely,fixingp(o)ofI f ismodestintheSara

asthenosphere, which is several hundred kilometers thick. Heat within the asthenosphere creates convection currents (similar to the currents that can be seen if food coloring is added to a heated container of water). Movement of convection currents causes tectonic plates to

These plates are sitting on the asthenosphere (plastic mantle). The transfer of Earth’s internal heat drives convection currents within the mantle that causes these plates to move. When hot rising currents reach the bottom of the plates, it causes them to move apart. When convection currents are sinking i

After the execution of FVCOM, the script extracts water level at each node point and water currents at each element center. An interpolation script calculates water currents value at each node point. Then water level and currents are written into forcing file

The IEC 60909-0 standard is used in order to calculate various types of short-circuit currents for the power system. The usage of the standard IEC 60909-0 is in some cases quite conservative, which is positive when calculating currents for a system of this type. For the standard IEC 60909-0,
