The extinction of some of medical plants is not only due to the overuse of them and the grazing pressure but also their incorrect exploitation methods. Ferula assafoetida is one of the most important medical plants in Iranian rangelands, which is gradually disappeared from its habitats due to destructive traditional exploitations. Therefore, in order to determine how different incision techniqu...
We generally investigate the scalar field model with the lagrangian L = F (X) − V (φ), which we call it General Non-Canonical Scalar Field Model. We find that it is a special square potential(with a negative minimum) that drives the linear field solution(φ = φ 0 t) while in K-essence model(with the lagrangian L = −V (φ)F (X)) the potential should be taken as an inverse square form. Hence their ...
Background: The aim of this study was to compare personality characteristics, job satisfaction and mental health of the personnel who experienced and didn’t experience a disaster in Zamyad Company. Methods: This is a casual-comparative study. The population consisted of all company personnel in Tehran (2500). Using random sampling, 120 people were selected, of whom 60 people had already experi...

Introduction This study investigated the effects of cocaine administration and parvalbumin-type interneuron stimulation on local field potentials (LFPs) recorded in vivo from medial prefrontal cortex (mPFC) six mice using optogenetic tools. Methods The network was subject to a brief 10 ms laser pulse, response for 2 s over 100 trials each subjects who showed stable coupling between mPFC optrode...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
Warm natural inflation is studied for the case of original cosine potential. The radiation bath during induces a dissipation (friction) rate in equation motion inflaton field, which can potentially reduce field excursion needed an observationally viable period inflation. We examine if thus provides mechanism to avoid large decay constant $f \gtrsim M_{\mathrm{pl}}$ cold Whereas temperature inde...
Climate change has a great impact on the species distribution range and many endangered plant species. Fritillaria imperialis as a species that is native to Central Zagros, Iran is a medicinal plant with great ecological and commercial profits. Its population has decreased considerably and the species would be endangered in later decades. Understanding the habitat needs of this species, evaluat...
