The United States had a negative gross domestic product growth in 1982. [5] The Republicans performed poorly in the 1982 elections. Dwight D. Eisenhower, John F. Kennedy, Richard Nixon, and Jimmy Carter lost an average of 12 seats in the United States House of Representatives in their first midterm.
All that is left is the constant term −1/12, and the negative sign of this result reflects the fact that the Casimir force is attractive. [ 20 ] A similar calculation is involved in three dimensions, using the Epstein zeta-function in place of the Riemann zeta function.
CHARGE syndrome (formerly known as CHARGE association) is a rare syndrome caused by a genetic disorder.First described in 1979, the acronym "CHARGE" came into use for newborn children with the congenital features of coloboma of the eye, heart defects, atresia of the nasal choanae, restricted growth or development, genital or urinary abnormalities, and ear abnormalities and deafness.

At 12 km altitude, above most of the atmosphere's protection, radiation as an annual rate rises to 20 mSv at the equator to 50–120 mSv at the poles, varying between solar maximum and minimum conditions. Missions beyond low Earth orbit transit the Van Allen radiation belts. Thus they may need to be shielded against exposure to cosmic rays, Van ...
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 ...
Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
The mass-to-charge ratio ( m / Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics .
