limited seismic data quality and complex tectonics make for less than ideal interpretation conditions. however, modern geometric attributes including coherency has shown to be effective in showing the lateral extents of subtle and small-scale geologic features not usually visible in conventional seismic sections. this geometric attributes are better suited than some older generation seismic att...
Morphological discrimination of geological top-formations is the supplemental procedure of geological mapping; so in situ measurements to register geomorphological data are unavoidable; though due to the impassable and fault cliffs field operations to visit all areas within a geological map is almost impossible. Microwave or radar remote sensing, via synthetic aperture radar (SAR) images is cap...
The Impact of Geological Units on the Groundwaters Quality of Hastijan, Southeastern of Delijan,Iran
This study was conducted to evaluate the quality of the groundwaters and the impact of geological units on these waters in Hastijan area. For this purpose, 11 samples of water resources have been collected with their appropriate dispersal. Physico-chemical parameters of Mn, Ni, Cd, Cu, Zn, As Fe, Cr, and ions K+, Na+,Ca2+, Mg2+, Cl-, So42-, Hco3- as well as indicators TH, TDS, EC, PH were deter...
The goal of conservation biology should be related to the preservation of species and also to the evolutionary and ecological processes that were responsible to form them and that are still acting. We review the conservation status of the species of tuco-tuco (Ctenomys torquatus, C. lami, C. minutus, and C. flamarioni) from southern Brazil, and relate these data to the geological history of a p...
Three-dimensional computer modelling of geological phenomena is rapidly emerging as a field within the already mushrooming science of computer visualization. In geological applications three-dimensional interpretations are routinely performed through the use of two-dimensional map data and knowledge about the geological history of an area. These interpretations are traditionally depicted with i...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

The U.S. Geological Survey (USGS) began an extensive groundand surfacewater quality study in July 1989 to define the baseline water quality within a southeastern Florida drainage district and to develop a data base for future waterresource planning and management. Results were published in a USGS report (Litzetz 1996), comparing groundand surface-water quality data (1989-94) to the Florida Depa...
