The research, which is written using the approach of historical sociology and descriptive and analytical methods, examines the interactions of trade unions after the Islamic Revolution. The examinations show that the first trade unions or trade unions emerged in England in the early eighteenth century.

Limits and restrictions of private quantum channel

We study private quantum channels on a single qubit, which encrypt given set of plaintext states P. Specifically, we determine all achievable states ρ (average output of encryption) and for each particular set P we determine the entropy of the key necessary and sufficient to encrypt this set. It turns out that single bit of key is sufficient when the set P is two dimensional. However, the neces...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers.
