the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

For a,b > 0 with a = b , let NS (a,b) denote the Neuman-Sándor mean defined by NS (a,b) = a−b 2arcsinh a−b a+b and Ap (a,b) , Lp (a,b) denote the r -order power and Lehmer means. Based on our earlier worker [27], we prove that αpAp < NS < Ap and Ap < NS βpAp holds if and only if p 4/3 and p p0 , respectively, where αp = ( 21/p−1 ) / ln(1+ √ 2) if p ∈ [1/4/3,∞), βp = ⎪⎨ ⎪⎩ NS (1,x0)/Ap (1,x0) if...

Nearly 40 years ago, Neuman (1968) developed an analytical solution for drawdown in a system of three aquifers separated by two aquitards when one of the aquifers is pumped at a constant rate. Whereas the simpler case of two aquifers separated by one aquitard has been presented by Neuman and Witherspoon (1969a), the full five-layer solution has not been previously evaluated. We do so here using...
