Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
An electric charge regarded as concentrated in a mathematical point, without spatial extent.
- ‘This point charge is a dipolar amino acid with its negative electron density directed toward the ionone ring or a negatively charged amino acid with its positive end distal from the [beta] ionone ring.’
- ‘Specifically, a positive point charge at 170 has no effect, but a negative point charge significantly reduces substrate turnover.’
- ‘All the atoms having the same point charge in the above database have been kept equivalent in the RESP calculations.’
- ‘This further supports the possibility of decreased interaction between the second point charge of the protein and the chromophore.’
- ‘The electric field anywhere outside a charged conducting sphere is shown to be exactly equal to that produced by a point charge of equal total charge located at the center of the sphere.’
