NADPH-diaphorase is a useful technique to reveal NO producing neurons at light microscopic level (LM). A modification of the technique using the tetrazolium salt BSPT as substrate, is useful to study the ultrastructure of NO neurons. The aim of this work was to perform a detailed analysis of NADPH-diaphorase reactive neurons in rat mesencephalon both at light and electron microscopic levels. NA...
Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. Life prediction of TBCs is important as high-temperature exposure degrades the coatings through mechanisms such as thermal fatigue and the formation and growth of thermally grown oxides (TGOs). This thesi...
In this study, a computational model which simulates the growth of crystalline deposits from dripping salt solution is developed and validated. This problem is of interest to the nuclear industry where the morphology of deposited material impacts on its associated criticality risk. An existing model for simulating geological-stalagmite formations is adapted to the case of dripping salt-solution...
Interactions with volcanic gases in eruption plumes produce soluble salt deposits on the surface of volcanic ash. While it has been postulated that saturation-driven precipitation of salts following the dissolution of ash surfaces by condensed acidic liquids is a primary mechanism of salt formation during an eruption, it is only recently that this mechanism has been subjected to detailed study....
Hormuz series in Zendan salt dome, Neoprotozoic-Early Cambrian rocks is located near Bandar-e-Lengeh in western Hormozgan Province. In this salt dome, iron calcic skarns are present near the basic igneous bodies that have copper hydrothermal deposits. Carbonate sedimentary sequences, carbonate tuffs and igneous rocks are the host rocks of these skarns. The calcsilicates in the endoskarn include...
Through this paper work we have analyzed the effect of different contaminants on the flashover by creating artificial pollution condition, considering the natural condition where more than one salt as contaminant deposits on the surface of insulator at a time, under the wet condition that cause flow of highly leakage current, that leads to flashover. We choses the mixture of different salts, so...
Salt flats (sabkha) are a recognized habitat for microbial life in desert environments and as analogs of habitats for possible life on Mars. Here we report on the physical setting and microbiology of interdune sabkhas among the large dunes in the Rub' al Khali (the Empty Quarter) in Liwa Oasis, United Arab Emirates. The salt flats, composed of gypsum and halite, are moistened by relatively fres...
