shielding

Pluralshieldings (some meanings)

1. 1
   verb

   Present participle and gerund of shield.

   The mother kept shielding her child from the photographers.

   Shielding sensitive equipment from radio interference takes careful design.

   Note

   The -ing form of shield does two jobs. After be or keep it carries an ongoing action (she was shielding her face); as a gerund it names the act itself, usually with from introducing the threat (shielding cables from interference). The same spelling has also settled into nouns with their own plural, like the spectroscopy term and the soccer skill.

2. 2
   noununcountable

   In soccer, the action of a player with the ball who keeps their body between the ball and a defender to protect it.

   Her shielding near the sideline bought time for teammates to join the attack.

   The striker is known for strong shielding with his back to goal.

   Note

   A skill strikers are praised for, used mostly with the back to goal or near the sideline to buy time. It is legal as long as the ball stays within playing distance and the player does not hold the defender off with the arms; once the ball is out of reach, stepping into the defender's path becomes impeding, which is a foul.

3. 3
   nouncountable or uncountable

   In NMR spectroscopy, the condition in which a local magnetic field is weakened by the presence of neighboring nuclei.

   Greater shielding of the methyl protons moves their signal upfield in the NMR spectrum.

   The calculated shieldings agreed closely with the measured spectrum.

   Oppositedeshielding

   Note

   Chemists treat it as a quantity a nucleus has more or less of: the electrons around it, set circulating by the applied field, produce a small opposing field, so the nucleus feels less than the full magnet. A more shielded nucleus resonates upfield, at a lower chemical shift. The plural shieldings refers to values computed for individual nuclei, and the reverse effect is called deshielding.
