forage is the main product of rangelands. so, determining its economic value as one of the main important nonmonetary functions can help managers to improve planning and optimal utilization management of rangelands. the main purpose of this study is to estimate the economic valuation of the forage of summer rangelands in nour-roud watershed basin in mazandaran province. consequently, total fora...

By the method of weight coefficients, techniques of real analysis and Hermite-Hadamard's inequality, a half-discrete Hardy-Hilbert-type inequality related to the kernel of the hyperbolic cosecant function with the best possible constant factor expressed in terms of the extended Riemann-zeta function is proved. The more accurate equivalent forms, the operator expressions with the norm, the rever...

$top$-filters can be used to define $top$-convergence spaces in the lattice-valued context. Connections between $top$-convergence spaces and lattice-valued convergence spaces are given. Regularity of a $top$-convergence space has recently been defined and studied by Fang and Yue. An equivalent characterization is given in the present work in terms of convergence of closures of $top$-filters.  M...

background : in spite of clinically useful photon and electron beams, high energy linacs produce secondary particles such as neutrons (photo-neutron production). neutrons have important roles during treatment with high energy photons in terms of protection and dose escalation. in this project, neutron dose equivalent of 18 mv varian accelerators is calculated by tld600 and tld700. materials and...

french revolution was a starting point for the emergence of concepts such as secular and laic. although most of the people in iran and arab countries consider them equivalent, purpose and lexical roots of these two should make a distinction between them. abuse or overuse of these terms by marxist, socialist, liberal, ond other movements has resulted in a misunderstanding of them and consequentl...

BFYM on commutative and noncommutative R is considered and a Seiberg– Witten gauge–equivalent transformation is constructed for these theories. Then we write the noncommutative action in terms of the ordinary fields and show that it is equivalent to the ordinary action up to higher dimensional gauge invariant terms.

as the financial structure of the public and private corporations in the islamic republic of iran differs from those operating in the west it appears to be a difficult task to find equivalent terminology in farsi for financial terms applied in english and french. by the same token, direct translation of the western financial jargons to farsi results in misunderstanding at hest and confusion at ...
