Low temperature, as a kind of stress factor, often leads to tomato growth stagnation or yield reduction even no harvest in production. At present, numerous genes have been shown be involved the regulation cold resistance tomato. Complex regulatory mechanisms responding low temperature are still unclear their details. In this study, six accessions (‘NL-7’, ‘NL-15’, ‘NL-18’, ‘NL-21, ‘NL-37’, and ...

Proof Since PATH is co-NL-complete, it suffices to prove that PATH ∈ NL. We’ll use the the read-once certificate definition of NSPACE(·). Let Ci def = {vertices reachable from s with ≤ i steps}. Clearly, C0 = {s}. To prove “vertex x ∈ V can be reached in at most i steps starting from s” (x ∈ Ci), it’s easy by providing the path as a certificate: s, v1, · · · , v`, x where ` < i. The verifier si...

This paper aims at investigating the acquisition of Italian complex predicates by native speakers of Persian. Complex predication is not as pervasive a phenomenon in Italian as it is in Persian. Yet Italian native speakers use complex predicates productively; spontaneous data show that Persian learners of Italian seem to be perfectly aware of Italian complex predicates and use this familiar fea...

Activities to reduce soil erosion, soil fertility and increasing agricultural production and finally crop income have considered fundamental in the implementation of sustainable agriculture in Iran. This research investigates the effects of no-till (NL) technology to reduce soil erosion and increasing agricultural income and eventually for achieving sustainability. Data were collected through q...
