Whether a given star is circumpolar at the observer's latitude (Î¸) may be calculated in terms of the star's declination (Î´). The star is circumpolar if Î¸+Î´ is greater than +90Â° (observer in northern hemisphere), or Î¸+Î´ is less than â90Â° (observer in southern hemisphere).
Countervailing duties. Countervailing duties (CVDs), also known as anti-subsidy duties, are trade import duties imposed under World Trade Organization (WTO) rules to neutralize the negative effects of subsidies. They are imposed after an investigation finds that a foreign country subsidizes its exports, injuring domestic producers in the importing country.
