in this paper, a bandpass filter with cutoff frequencies 1.7-11.5ghz have been implemented. for construction of this filter, the first two lowpass and highpass filters with cutoff frequencies 1.7 ghz and 11.5ghz respectively have been designed and then they use in series. we design cutoff frequencies independently, consequently, designing cutoff frequencies doesn’t interfere with each other. th...

Background: The aim of present study was to analyze the effectiveness of electron filters in the Telecobalt radiotherapy treatment by simulation technique.  Materials and Methods: The BEAMnrc Monte Carlo code was used to simulate the electron filters of thickness of 0.5 gm/cm2 below the trimmer bar for 35 × 35 cm2 field size in Theratron Equinox-80 telecobalt unit. The electron filters were mad...

the different constructions of [ah] which is an infinitive are prevalent in the dialect of the historical village of xanik and its neighboring villages. singular second person paradigm in present tense of [ah] infinitive in the dialect is a survivor of sanskrit and old persian languages. some constructions of this infinitive are widely used, because they are attributive verbs meaning is being a...

At present, the filter theory of $BL$textit{-}algebras has been widelystudied, and some important results have been published (see for examplecite{4}, cite{5}, cite{xi}, cite{6}, cite{7}). In other works such ascite{BP}, cite{vii}, cite{xiii}, cite{xvi} a study of a filter theory inthe more general setting of residuated lattices is done, generalizing thatfor $BL$textit{-}algebras. Note that fil...
