The pistachio twig borer moth, Kermania pistaciella Amsel (Lep.: Tineidae) is one of the most important pests of pistachio trees (Pistacia vera L.) in Iran. This study was carried out in two pistachio orchards of Rafsanjan area. Periods of pupal cocoon and adult emergence were recorded in two pistachio orchards for four years. Minimum threshold temperatures were calculated according to the leas...

In many species, empirical data suggest that temperatures less than 1 month before breeding strongly influence laying date, consistent with predictions that short lag times between cue and response are more reliable, decreasing the chance of mismatch with prey. Here we show in European starlings (Sturnus vulgaris) that mid-winter temperature ca 50-90 days before laying (8 January-22 February) s...

In this research, the activity of MnO, produced during steel making in aluminate-rich slags, was investigated. According to thermodynamic equations and mathematical calculation, a series of relations was obtained for evaluation of oxide activity using Masson’s theory. The obtained relations were solved according to Levenberg- Marquardt method and using Matlab software. The results were correlat...
