در دهه اخیر، ساختار فراماده الکترومغناطیسی توجه زیادی را در فیزیک و جوامع مهندسی به خود جلب کرده است. فراماده ساختاری است الکترومغناطیسی با خصوصیات همگن ومصنوعی که دارای خواص غیر عادی می¬باشد. این ساختارضریب گذردهی الکتریکی منفی و ضریب نفوذپذیری مغناطیسی منفی دارد و تحت عنوان ساختار چپگرد شناخته می¬شود. ابعاد سلولی آنها از طول موج کوچکتر است. این ساختار در طبیعت یافت نمی شوند. انتشار امواج در ا...

it seems using the maxwell-stefan (m-s) diffusion model in combination with the vacancy solutiontheory (vst) and the single-component adsorption data provides a superior, qualitative, andquantitative prediction of diffusion in zeolites. in the m-s formulation, thermodynamic factor (г) isan essential parameter which must be estimated by an adsorption isotherm. researchers usually utilizethe simp...

we introduce the notions of t-dual rickart and strongly t-dual rickart modules. we provide several characterizations and investigate properties of each of these concepts. it is shown that every free (resp. finitely generated free) $r$-module is t-dual rickart if and only if $overline{z}^2(r)$ is a  direct summand of $r$ and end$(overline{z}^2(r))$ is a semisimple (resp. regular) ring. it is sho...

The transport system of many Ukrainian cities does not meet the EU standards and requirements. There is a need to improve urban transport networks, to use transport potential efficiently on the basis of environmental logistics and to improve environmental safety as one of the principles of sustainable transport development. The systems model to create an ecologically safe logistics system of pu...

The debate over the processing mechanism for inflectional morphology has focused largely on the German plural system because it seems to contain a minority default, a form that has low frequency but high productivity in diverse contexts. Child overgeneralization patterns, phonological similarity effects, restrictions on compounding, reaction times, and neural dissociations have all been used to...

Silver particles of nanometric size were prepared from silver sulphate solution using Curcuma Longa and Zingiber Officinale rhizome extracts. The reaction was completed at 3 hours on using Curcuma Longa rhizome extract as reducing agent, making it one of the fastest biosynthesis route reported so far. The plasmon bands at 420 nm in the UV visible spectra are broad with an absorption tail in the...

Location and types of sensors may be integrated for simultaneous achievement of water security goals and other water utility objectives, such as regulatory monitoring requirements. Complying with the recent recommendations on dual benefits of sensors, this study addresses the optimal location of these types of sensors in a multipurpose approach. The study presents two mathematical models for ...

The dual fuel engines at part loads inevitably suffer from lower thermal efficiency and higher carbon monoxide and unburned fuel emission. This work is carried out to investigate combustion characteristics of a dual fuel (dieselgas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. The authors developed software in ...

A generalized gauge invariant Ising model on random surfaces with non-trivial topology is proposed and investigated with the dual transformation. It is proved that the model is self-dual in case of a self-dual lattice. In special cases the model reduces to the known solvable Ising-type models.
