Jujube trees (Ziziphus jujuba) are typically hardy to USDA zone 6 but can sometimes survive in zone 5 with winter protection. In zone 4, they may struggle due to the colder temperatures, so it is recommended to plant in a sheltered location and provide winter protection like mulching or wrapping the tree.
The "Tigger zone" in a unipolar neuron is the initial segment of the axon where action potentials are generated. Here, graded potentials from the dendrites accumulate and if they reach a certain threshold, an action potential is triggered.
The trigger zone of a neuron includes the axon hillock, where graded potentials are summed together to determine if an action potential will be initiated. It is the region where voltage-gated sodium channels are concentrated and play a crucial role in generating an action potential. If the depolarization at the trigger zone reaches a certain threshold, an action potential will be generated and propagated down the axon.
Differential protection provides fast and selective fault detection by comparing current entering and leaving a zone to identify internal faults within the protected zone. It can operate effectively even when the fault currents are low or the system has long transmission lines. This helps to prevent damage to equipment and maintain system reliability by quickly isolating faulty sections.
The ocean zone where waves and currents mix the water is called the "surface zone" or "mixed layer." This layer is characterized by turbulent mixing caused by wave action and wind-driven currents, resulting in the uniform distribution of temperature and salinity. It is critical for the exchange of gases between the atmosphere and the ocean.
German Zone of Protection in Slovakia was created in 1939.
A zone of action is an area of responsibility defined by boundaries and assigned to a military unit in any situation involving action.
Differential relays should only operate for faults within the zone of protection, so there is no coordination issue. The reason to coordinate relays is for backup protection (a relay at a remote substation sees faults that should be cleared by another relay, for example). A differential will not see this fault, since it is external to it's zone of protection.
