in this paper, we introduce a method by which we can find a close connection between the set of prime $z$-ideals of $c(x)$ and the same of $c(y)$, for some special subset $y$ of $x$. for instance, if $y=coz(f)$ for some $fin c(x)$, then there exists a one-to-one correspondence between the set of prime $z$-ideals of $c(y)$ and the set of prime $z$-ideals of $c(x)$ not containing $f$. moreover, c...

statement of problem: nowadays, evaluation of the development of occlusion in deciduous teeth for creating corrective occlusion in permanent teeth is one of the most important objectives of pediatric dentistry. in other countries, a vast number of researches have been accomplished on the details of occlusion in deciduous teeth. but, unfortunately, there is still no accurate information about th...

We present the development of a physically-based dust source map for GOCART-AFWA module in WRF-Chem model. The new parameterization is based on MODIS-NDVI and an updated emission strength computed every 15 days from latest satellite observations. Modeling simulations period April–May 2017 over Mediterranean, north Africa, Middle East are compared with observations AOD at 31 AERONET stations. ca...

in this paper, we consider a generalization of the real normed spaces and give some examples.

examining the planning of cemeteries in the urbanism system of iran does not show a goodcondition. in fact, cemeteries in the most persian cities have become large-scale open spaces outside the city. this couldcause irreparable damage to the cities because of the partial and/or improper use of the capacity of urban lands. alongwith this, historical cemeteries within the cities have been abandon...

we study umbilic (space-like) submanifolds of pseudo-riemannian space forms, then define totally semi-umbilic space-like submanifold of pseudo euclidean space and relate this notion to umbilicity. finally we give characterization of total semi-umbilicity for space-like submanifolds contained in pseudo sphere or pseudo hyperbolic space or the light cone.a pseudo-riemannian submanifold m in (a ps...

in this paper, we formalize the menger probabilistic normed space as a category in which its objects are the menger probabilistic normed spaces and its morphisms are fuzzy continuous operators. then, we show that the category of probabilistic normed spaces is isomorphicly a subcategory of the category of topological vector spaces. so, we can easily apply the results of topological vector spaces...
