For a hundred of years electricity and its delivery were thought to be inseparable. Since the late-1980s and early-1990s things began to change. Due to diverse reasons [13] both developed and developing countries began to abandon the idea of an electricity industry vertically integrated to adopt a new model that allows competition and choice in electricity. The idea of commercial separation of ...

When two patterns occur equally often in a set of permutations, we say that these patterns are equipopular. Using both structural and analytic tools, we classify the equipopular patterns in the set of separable permutations. In particular, we show that the number of equipopularity classes for length n patterns in the separable permutations is equal to the number of partitions of the integer n− 1.

We present the details of a model theoretic proof of an analogue of the Manin-Mumford conjecture for semiabelian varieties in positive characteristic. As a by-product of the proof we reduce the general positive characteristic Mordell-Lang problem to a question about purely inseparable points on subvarieties of semiabelian varieties.

The use of phrasal verbs is problematic for Iranian EFL learners. Accordingly, the present studyinvestigated the performance of Iranian intermediate and advanced EFL learners in separable andinseparable verbs. The total population of the study was one hundred female Iranian EFLlearners who studied English as foreign language in Kaj language institute in Qazvin, Iran. Theparticipants were all fe...

We provide fundamental results of the structural theory computably separable models and consider applications this to effective linear orders theoretical informatics.
