during the period between the presidential election and the inauguration, the outgoing president is a lame duck, while the incoming president heads a presidential transition team to ensure a smooth handover of power. if a sitting president has won re-election, the incumbent is not referred to as a president-elect as he or she is already in office and is not waiting to become president. likewise, if a vice president succeeds to the presidency by way of the president's death, resignation or removal (via impeachment) from office, that person never holds the title of president-elect, as they would become president immediately. the most recent president-elect is former minister of foreign affairs nana akufo-addo of the new patriotic party, who won the presidential election on 9 december 2016.

while one separatory funnel is useful in separating certain compound mixtures with a carefully formulated biphasic solvent system, a series of separatory funnels may be employed to separate compounds that have different partition coefficients. countercurrent distribution, therefore, is a method of using a series of vessels (separatory funnels) to separation compounds by a sequence of liquid-liquid extraction operations. contrary to liquid-liquid extraction, in the ccd instruments the upper phase is decanted from the lower phase once the phases have settled. first, a mixture is introduced to vessel 1 (v) charged with both phases and the liquid-liquid extraction process is performed. the upper phase is added to a second vessel (v) which already holds fresh lower phase. fresh upper phase is added to v. both vessels are shaken and allowed to settle. upper phase from v is transferred to v at the same time the upper phase from v is transferred to v which already holds fresh lower phase. fresh upper phase is added to v, all three vessels are shaken and settled and the process continues. compounds that are more soluble in the upper phase than lower phase faster and farther down the series of vessels (the "train") while those compounds which are more soluble in the lower phase than the upper phase tend to lag behind. a compound insoluble in the upper phase will remain in v while a compound insoluble in the lower phase will stay in the lead vessel.
