Agricultural investigations use computer models for simulation of crop growth and field water management. By using these models, the effects of plant growth parameters on crop yields are simulated, hence, the experimental costs are reduced. In this paper, the model of MSM (Maize Simulation Model) was calibrated and validated for the prediction of maize forage production at Agricultural College,...

To investigate the effect of  the timing of nitrogen fertilizer application on grain yield and quality of bread wheat cultivars under terminal drought stress conditions, two field experiments were conducted at Agricultural Research Station of Miandoab in West Azerbaijan, Iran, in 2013-2014 and 2014-2015 cropping seasons. Experimental treatments were arranged as split plot factorial in randomiz...

OBJECTIVE The aim of this study was to assess the efficacy of apical negative pressure (ANP), manual dynamic agitation (MDA), passive ultrasonic irrigation (PUI) and needle irrigation (NI) as final irrigation activation techniques for smear layer removal in curved root canals. MATERIALS AND METHODS Mesiobuccal root canals of 80 freshly extracted maxillary first molars with curvatures ranging ...

The articles [3], [1], [4], and [2] provide the notation and terminology for this paper. In this paper x, y, X , Y are sets. We introduce G-net structures which are extensions of 1-sorted structure and are systems 〈 a carrier, an entrance, an escape 〉, where the carrier is a set and the entrance and the escape are binary relations. Let N be a 1-sorted structure. The functor echaos(N) yields a s...
