This paper presents results of an assessment of dominant hydro-geochemical processes controlling groundwater chemical composition, using an integrated application of cluster analysis and factor analysis. The area is located in south of saline playa and in Arak city. Cluster analysis classified samples into two main clusters according to their dominant chemical composition: cluster A (dominant c...

in recent decades, economic development and population growth in the world has led to the expansion of road networks. therefore the use of optimum methods for repairing and maintenance of these roads is considered as an important value. today one of the options in this regard, is the use of asphalt recycling technology. the present study which took place in the summer of 2015 in iran, lorestan ...

in order to evaluate the seed yield and qualitative traits and oil in some winter rapeseed (brassica napus l.) varieties as affected by micronutrient elements, this experiment was performed during 2011 - 2012 cropping seasons as split plot arrangement in randomized complete block design with three replications, in arak, iran. micronutrient fertilizers including of zero as check, fe, zn, mn, fe ...

The present study investigated NO3- and Br- contamination in groundwater of Arak aquifer, Markazi province, Iran. Correlation and factor analyzes were used to detecti nterrelations and sources of NO3- and Br- ion concentration and other physicochemical variables. No correlation was observed between NO3- and otherscontents, but a positive correlation was identified between Br-and other majorvari...

We consider polygonal Markov fields originally introduced by Arak and Surgailis [1, 2]. Our attention is focused on fields with nodes of order two, which can be regarded as continuum ensembles of non-intersecting contours in the plane, sharing a number of salient features with the two-dimensional Ising model. The purpose of this paper is to establish an explicit stochastic representation for th...
