A surface charge is an electric charge present on a two-dimensional surface. These electric charges are constrained on this 2-D surface, and surface charge density, measured in coulombs per square meter (C•m −2 ), is used to describe the charge distribution on the surface. The electric potential is continuous across a surface charge and the ...
The Seventh-day Adventist Church opposes abortion, believing it can have long-term negative effects on both the individuals involved and society as a whole. In an official statement on the "Biblical View of Unborn Life", the church declared that an unborn child is considered by God to be a living individual. [ 75 ]
The CODATA recommended value is −e/m e = −1.758 820 008 38 (55) × 10 11 C⋅kg −1. [2] CODATA refers to this as the electron charge-to-mass quotient, but ratio is still commonly used. There are two other common ways of measuring the charge-to-mass ratio of an electron, apart from Thomson and Dunnington's methods.
A constant fraction discriminator ( CFD) is an electronic signal processing device, designed to mimic the mathematical operation of finding a maximum of a pulse by finding the zero of its slope. Some signals do not have a sharp maximum, but short rise times . Typical input signals for CFDs are pulses from plastic scintillation counters, such as ...

e. The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.
As of 2010, there were nearly 14 million Jews around the world, roughly 0.2% of the world's population at the time. [252] According to the 2007 estimates of The Jewish People Policy Planning Institute , the world's Jewish population is 13.2 million. [ 253 ]
The fractional excretion of sodium ( FENa) is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is measured in terms of plasma and urine sodium, rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption.
