Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [ 1 ] [ 2 ] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after ...
This feature can be used to reduce current in the depressions, and exposes ridges and edges to higher currents. Undesirable polarization can be suppressed by vigorous agitation of the electrolyte, or – when agitation is impractical (such as in a stationary battery) – with a depolarizer.
Polar Caravans (Swedish: Polarvagnen, often abbreviated to Polar) is a Swedish manufacturer of caravans. The caravans are manufactured in Dorotea, Västerbotten County, employing nearly 100 people. The company is now called SoliferPolar AB. Adjacent to the factory in Dorotea is a caravan museum. [1]

[12] Coca-Cola filed a motion for an injunction against Polar in United States District Court in Boston , contending that the commercial made Coke's product appear impure.
Suppose we have a continuous differential equation ′ = (,), =, and we wish to compute an approximation of the true solution () at discrete time steps ,, …,.For simplicity, assume the time steps are equally spaced:
At least in the mainstream media, the de facto 21st century analogue of Hilbert's problems is the list of seven Millennium Prize Problems chosen during 2000 by the Clay Mathematics Institute. Unlike the Hilbert problems, where the primary award was the admiration of Hilbert in particular and mathematicians in general, each prize problem ...
A polar aprotic solvent is a solvent that lacks an acidic proton and is polar. Such solvents lack hydroxyl and amine groups. In contrast to protic solvents, these solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors. Many solvents, including chlorocarbons and hydrocarbons, are classifiable as aprotic ...
