We developed numerical code for calculation of the extragalactic component of the spectra of leptons, nucleons and γ-rays resulting from " top-down " (non-acceleration) models for the case of uniform and isotropic source distribution. We explored two different classes of " top-down " scenarios: the wide earlier investigated class of X particles coming from collapse and/or annihilation of cosmic...

Introduction: In stroke models, Inducible Nitric Oxide Synthase (iNOS) expression initiates cellular toxicity due to excessive Nitric Oxide (NO) generation. Anchusa italica is a medicinal herb with anti-inflammatory, antioxidant and neuroprotective properties. This study evaluated the antioxidant activity and NOS mRNA expression of the Hydroalcoholic Extract Of Anchusa Italica (HEAI) in an expe...

Due to the importance of energy consumption in a steam network of oil refinery as a significant unit, present study is concerned with the optimization of an oil refinery steam network. Here, the attempt was made to use concepts such as first and second thermodynamic laws, thermo-economic, environmental and economic discussions to investigate three different scenarios about Tehran refinery steam...

abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...

Recent observations indicate that the universe’s expansion has been accelerating of late. But recent theoretical work has highlighted the difficulty of squaring acceleration with the underlying assumptions of string theory, disfavoring most models of quintessence. because they predict eternal acceleration. We show that one of the simplest and most motivated quintessence models described by an e...
