terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
in the current study the effect of casimir force and squeezed film damping on the pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems is investigated separately. linear elastic membrane theory is used to model the static and dynamic behavior of system for strip, annular and disk geometries. squeezed film damping effect is modeled using...
Objectives: The purpose of this study was to investigate relationship between body composition indices with static and dynamic balance and rate of falling in active elderly people. Methods & Materials: This research was a correlation study. Active elderly women volunteered for participation in this research (n=45). Body composition indices (body fat mass, fat free mass, body mass index, wais...
To cope with droughts and water scarcity in semi-arid to sub-humid climates require the development of preparedness measures. For irrigated agriculture these include the identification of irrigation scheduling strategies that minimize the water demand with acceptable impacts on yields Those strategies may be produced by simulation and focus on different levels of water demand, from average to d...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
In order to investigate the effect of water deficit tension on different growth stages on yield, yield components and produced grain quality of sorghum seeds cultivars, an experiments was performed as split plots based on randomized complete blocks design with four replications in Isfahan Ghiam Cultivation and Cattle Farm Company in 2017. The main factor including irrigation cut at four levels...
Cortical control of the sensory output of muscle spindles was studied in thirteen anesthetized cats in the present experiment. Gamma motoneuron activity was monitored during electrical stimulation of the sensorimotor cortex while recording from single primary afferents from the tenuissimus muscle. Findings are as follows: 1. The state of anesthesia is crucial in obtaining reproducible resu...
In this study, a model was developed to determine the optimal irrigation schedule for the Qazvin Plain in such a way that economic productivity is maximized with the amount of water available and the area under cultivation. The AquaCrop plant growth model was used to determine crop performance in different irrigation programs. The plant growth model was connected to the MATLAB programming envir...
This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...
the effects of water deficit on grain yield, yield components and the physiological char-acteristics of barley (hordeum vulgare l.) varieties were studied in a split plot design dur-ing the 1999-2000 growing season in karaj, iran. five irrigation levels [0, 25, 50, 75, and 100% crop water requirements (cwr)] and six barley varieties karoon kavir , rei-hani(drought tolerant), torkman , c-74-9 (i...
