1) hamistân, hâjuheš; 2) hâjuheš
1) A position of two bodies in the → solar system
when they have the same → celestial longitude,
seen from the Earth. The bodies can be a → planet
and the → Sun, two planets or the
→ Moon and a planet. The
→ superior planets are in conjunction with the Sun,
when, seen from the Earth, they are right behind the Sun. The
→ inferior planets, such as Mercury and Venus,
have two conjunctions with the Sun: → inferior conjunction,
when they are between the Earth and the Sun, and
→ superior conjunction, when they are on the other
side of the Sun.

Hamistân "standing together," from ham- "together,"
→ com- + istân "standing," from istâdan
"to stand" (cf. Skt samstha "an assembly"), Mid.Pers.

A → proposition of the form "A or B" (A ∨ B), where A and B are themselves propositions. A disjunction is → true when one or the other of its components (called → disjuncts) is true, and false otherwise.
Fr.: conjonction inférieure
The conjunction of an inferior planet with the Sun when the planet is between the Sun and the Earth. → superior conjunction.
juhe-ye Josephson (#)
Fr.: jonction Josephson
In a → semiconductor device, a region of transition between semiconducting regions of different electrical properties.
Junction "act of joining," from L. junctionem, noun of action from jungere "to join," cognate with Pers. yuq, juhé, as below; PIE base *yeug- "to join,"
Juheš, from juh, variant of yuq "yoke," Mid.Pers. jug, ayoxtan "to join, yoke;" Av. yaog- "to yoke, put to; to join, unite;" cf. Skt. yugam "yoke;" Hittite yugan "yoke;" Gk. zygon "yoke," zeugnyanai "to join, unite;" L. jungere "to join," as above; O.C.S. igo, O.Welsh iou, Lith. jungas O.E. geoc.
Fr.: jonction semi-conducteur
In a semiconductor device, a region of transition between semiconducting regions of different electrical properties.
→ semiconductor; → junction.
Fr.: conjonction supérieure
The conjunction of a planet with the Sun which occurs when the planet is beyond the Sun. → inferior conjunction.
Fr.: conjonction triple
A rare event involving a particularly intricate set of movements of two planets or a planet and a star where they meet each other three times in a short period either in opposition or at the time of inferior conjunction, if an inferior planet is involved. The visible movement of the planet or the planets in the sky is therefore normally prograde at the first conjunction, retrograde at the second conjunction and again prograde at the third conjunction.
