Specimens of geopolymeric concrete on basis waste iron ore enrichment Dashkesan’s deposit and bottom ash combustion domestic were obtained. Herewith ratio mixture to binder made up 80:20. At obtaining geoconcrete specimens the concentration in was variated limits 10-50%wt. Normality water solution alkali activator from 1N 8N. Maximal values absorption containing 10, 20, 30, 40 50%wt correspondi...

It is well known that some XML elements correspond to objects (in the sense of object-orientation) and others do not. The question we consider in this paper is what benefits we can derive from paying attention to such object semantics, particularly for the problem of keyword queries. Keyword queries against XML data have been studied extensively in recent years, with several lowest-common-ances...

In the direction of sustainable mining solid waste management and eventually zero-waste production, MagWasteVal research program aimed to achieve proper handling massive quantities extractive originating from magnesite mines after enrichment process useful ore. The main objectives this project were both investigation geochemical variables affecting serpentinization (degradation) respected explo...

The demands for increasing the efficiency and lowering the environmental effects in iron and steelmaking industries have given rise to interests in application of direct reduction (DR) processes for production of iron by different gases. These advancements require comprehensive models for better control of the process conditions and the product properties. In the present thesis fundamental aspe...

The Mahin area is a part of TaromHashtjin zone that located in west of Qazvin province in northwest of Iran. Many copper and base metals ore deposits are hosted by this zone. High potential localities identification in this area is very necessary. The objective of this research, is finding hydrothermal alteration zones by remote sensing methods and best processing technique of Advanced Spacebor...
