Chah-Shoor kaolin mine is located about 150 km southeast of Isfahan and also located in the central Iran structural zone, Urumieh-dokhtar volcanic belt. Eocene Igneous rocks consist of andesite, tuffs and quaternary deposits have covered the area. Based on petrographic studies, the main minerals in the volcanic rocks are K- feldspar, quartz and plagioclase. Hydrothermal alteration has produced ...
Les dcouvertes de ptrole ou de gaz dans des conditions svres de temprature (plus de 150¡C) ou de pression (plus de 50 MPa) se comptent dans plusieurs bassins travers le monde. En mer du Nord, on prvoit de mettre en production des gisements dont les conditions de fond vont jusqu' 110 MPa et 190¡C. Ces caractristiques constituent un dfi pour la prdiction des proprits des fluides de ...
Une mthode indirecte pour cartographier les gaz brls dans un moteur allumage command a t dveloppe. Elle est fonde sur une visualisation partir de la fluorescence induite par laser (LIF) du mlange air-carburant non brl et ensemenc avec du biactyl. Les gaz brls provenant la fois des recirculations internes et externes sont observs. Ce type de diagnostic est complmentaire d...
BACKGROUND Fluoride is an essential element for human health. However, excess fluoride in drinking water may cause dental and/or skeletal fluorosis. Drinking water is the main route of fluoride intake. The aim of the present study was to measure fluoride levels in human breast milk collected from two regions of Golestan Province, northern Iran with different amount of fluoride concentration of ...
The interparticle interactions in ultracold atomic gases can be tuned using Fano–Feshbach scattering resonances, which occur in low–energy collisions between two atoms. These resonances are usually obtained using an external static magnetic field. They turn ultracold atomic gases into an experimental playground for the investigation of novel phases in which Quantum Physics plays a key role. The...
