Initially, prajna is attained at a conceptual level by means of listening to sermons (dharma talks), reading, studying, and sometimes reciting Buddhist texts and engaging in discourse. Once the conceptual understanding is attained, it is applied to daily life so that each Buddhist can verify the truth of the Buddha's teaching at a practical level. Notably, one could in theory attain Nirvana at any point of practice, whether deep in meditation, listening to a sermon, conducting the business of one's daily life, or any other activity.
Initially prajna is attained at a conceptual level by means of listening to what?
****
The answer: sermons

Important fragments survived from the mosaic floor of the Great Palace of Constantinople which was commissioned during Justinian's reign. The figures, animals, plants all are entirely classical but they are scattered before a plain background. The portrait of a moustached man, probably a Gothic chieftain, is considered the most important surviving mosaic of the Justinianian age. The so-called small sekreton of the palace was built during Justin II's reign around 565577. Some fragments survive from the mosaics of this vaulted room. The vine scroll motifs are very similar to those in the Santa Constanza and they still closely follow the Classical tradition. There are remains of floral decoration in the Church of the Acheiropoietos in Thessaloniki (5th6th centuries).
What was the small vaulted room in the Great Palace of Constantinople called?
****
The answer: small sekreton

In electric power distribution, capacitors are used for power factor correction. Such capacitors often come as three capacitors connected as a three phase load. Usually, the values of these capacitors are given not in farads but rather as a reactive power in volt-amperes reactive (var). The purpose is to counteract inductive loading from devices like electric motors and transmission lines to make the load appear to be mostly resistive. Individual motor or lamp loads may have capacitors for power factor correction, or larger sets of capacitors (usually with automatic switching devices) may be installed at a load center within a building or in a large utility substation.
How are capacitors used for for power factor correction prepared?
****
The answer:
as three capacitors connected as a three phase load
