In this paper, on the basis of tight-binding model and a generalized Green- function method as well as Lanczos algorithm procedure, the effects of the metal-molecule coupling(MMC) strength on the electronic transmission through a metal-single molecule-metal(MMM) system is investigated. Using the Landauer formalism we study some of the significant conductance properties of this system as a mol...

Objective(s): Asthma, the most frequent chronic respiratory disease, results from a complex interaction between multiple genes and environmental factors. To date, more than 100 candidate genes and single nucleotide polymorphisms (SNPs) have been reported to be associated with asthma. One of the discovered genes related to asthma is ADAM33. However, the relationship between ADAM33 gene polymorph...
توربین های گازی بعنوان سیستم های تولید قدرت در اشل صنعتی در کشورهای جهان از جایگاه ویژه ای برخوردارند. مسئله اثرات زیست محیطی محصولات احتراق این توربینها از بحث های روز مورد توجه در اشل تحقیقاتی و صنعتی می باشد. روشهای کاهش آلودگی بخصوص nox مسئله اصلی مورد مطالعه در تحقیق می باشد. در این تحقیق در ابتدا بمنظور آگاهی از محصولات احتراق تحت شرایط کاری مختلف به مدلسازی احتراق پرداخته ایم . احتراق با...
Electrochemical aptamer-based sensors attract a lot of interest as useful methods because of their low cost, accuracy, sensitivity, and simplicity. An electro-active redox molecule comprises the main part of the electrochemical-based sensors. Ferrocene is one of the most popular redox molecule used in biosensor fabrication. But, instability of ferrocenium ion in strong nucleophilic reagents...
Nucleic acids have been widely recognized as potential targets in drug discovery and aptamer selection. Quantifying the interactions between small molecules and nucleic acids is critical to discover lead compounds and design novel aptamers. Scoring function is normally employed to quantify the interactions in structure-based virtual screening. However, the predictive power of nucleic acid-ligan...
objectives: nitric oxide (no) is a signaling molecule that mediates mechanical bone loading. cyclic guanosine 3', 5' monophosphate (cgmp) is a no-induced effector molecule. the aim of this study was to assess the effect of no-cgmp pathway on orthodontic tooth movement (otm) in rats by use of two phosphodiesterase 5 (pde5) inhibitors namely sildenafil and tadalafil as chemical tools. materials a...
nitric oxide (no) is an important signalling molecule with diverse physiological functions inplants. in the last years, many advances have been obtained regarding no synthesis and its physiologicaleffects in plants. it was found to play a crucial role in plant growth and development, starting fromgermination to flowering, ripening of fruit and senescence of organs, respiratory metabolism, as we...
