The construction industry is particularly responsible for the appearance of earth and environment its partial degradation related to climate warming through production cement, brick burning, processing substrates building materials (lime, gypsum, polystyrene, processed materials, etc.). An important aspect 21st century has been overproduction excessive use natural resources, including sand. pur...

background and objectives : zeolite is a group of anionic hydrated aluminosilicates with a tridimensional structure which has great implications in remediation of water, sediment and soil resources. the present research aims at physicochemical investigation, clay mineralogy and micromorphology of soils along rafsanjan-sarcheshmeh lithotoposequence, southeastern iran. materials and methods: the ...

Formamides represent an important class of intermediates in various organic syntheses. They have been used in the synthesis of some pharmaceutically important compounds such as Fluoroquinolones [1], 1, 2 dihydro quinolones [2] and Nitrogen based heterocyclic compounds [3]. In Lewis bases, its main importance is to catalyze some important reactions such as allylation [4] and hydrosilyation of ca...

Abstract The alkaline Cho Don complex in NE Vietnam comprises several mafic-felsic suites related to the widespread magmatism developed during early-Permian–late-Triassic. contribution explores petrogenesis of nepheline syenite from Bang Phuc massif and its petrogenetic relationship with cogenetic scapolite-rich gabbro. formed through fractional crystallization pristine mantle-derived basaltic ...

This work aims to extract the mineralogical constituents of the Lahroud Hyperion scene situated in the NW of Iran. Like the other push-broom sensors, Hyperion images suffer from spectral distortions, namely the smile effect. The corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. The common “column me...

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...
