The Cold War period was widely understood as one of bipolarity with the USA and the USSR as the world's two superpowers, whereas the end of the Cold War led to unipolarity with the US as the world's sole superpower in the 1990s and 2000s. Scholars have debated how to characterize the current international system. [2] [3] [4]
The use of the bipolar option does not require the placement of a return electrode because the current only passes between tines of the forceps or other bipolar output device. Electrosurgery should only be performed by a physician who has received specific training in this field and who is familiar with the techniques used to prevent burns.
The term bipolarization was used to describe the division of the world during the Cold War (1947–1991) between the communist Eastern Bloc, centred on the USSR, and the capitalist Western Bloc. It also defines the state of international relations during this period, dominated by the confrontation between two superpowers , the United States ...
In electronics, the Gummel plot is the combined plot of the base and collector electric currents, and , of a bipolar transistor vs. the base–emitter voltage, , on a semi-logarithmic scale. This plot is very useful in device characterization because it reflects on the quality of the emitter–base junction while the base–collector bias, V bc ...
[2] [3] [7] [8] He also developed the three methods that have been used to apply high-frequency current to the body: contact electrodes, capacitive plates, and inductive coils. [3] Nikola Tesla first noted around 1891 the ability of high-frequency currents to produce heat in the body and suggested its use in medicine. [1]
The remaining terms predict that the potential of a dipole source (ℓ=1) drops off as 1/r 2. The magnetic field, being a derivative of the potential, drops off as 1/r 3. Quadrupole terms drop off as 1/r 4, and higher order terms drop off increasingly rapidly with the radius. The radius of the outer core is about half of the radius of the Earth.
Bipolar disorder is a serious mental health condition affecting 2.8 percent of adults in the United States. It involves episodes of mania (extreme highs) and depression (intense lows).
The pacemaker current (I f, or I Kf, also called funny current) is an electric current in the heart that flows through the HCN channel or pacemaker channel. Such channels are important parts of the electrical conduction system of the heart and form a component of the natural pacemaker .
