Cost and energy payback time in relation to solar cell performances is one of the key parameters considered for mass application. In this research work, a low-cost, easily fabricated, more eco-friendly photovoltaic device was successfully developed using dye synthesized from teak plant leaves. The dye-sensitized (DSSC) made up photoelectrode counter electrodes. prepared by depositing zinc paste...

It is well known that silver nanoparticles have been used for centuries as a yellow tint for glasses, which made the silver a revolutionary colorant used to paint the windows of the religious places. An ion exchange non-conventional process comely called medieval pigment without using molten salts has long been used as a method for coloring the glass. In the same subject, this work aims to stud...

Three babies said to have had 'meconium stained liquor' were subsequently found never to have passed meconium. The green discoloured liquor was the result of bilious vomiting in utero secondary to intestinal obstruction.

Zinc-fluoride glass nanoparticles (Zinc-F) release several ions, such as fluoride, zinc and calcium through acid-base reactions. The aim of this study was to evaluate the antibacterial cytotoxic properties Zinc-F. Antibacterial tests showed that a Zinc-F eluting solution significantly reduced turbidity colony-forming units Streptococcus mutans Actinomyces naeslundii, compared calcium-fluoroalum...

background: direct identification of leishmania species in giemsa-stained slides without parasite culturing in the areas where multiple species exist, is very helpful. this study was designed to isolate leishmani spp. from giemsa-stained smears and to characterize them by pcr technique. methods: a total of 48 giemsa-stained slides from confirmed cases of leishmaniasis were examined under a ligh...

In Europe, the use of colored stained glass in theconstruction church windows was common,reaching their peak during Gothic period. On theother hand, tendency to glass, calledOrosi (Sash), Iranian architecture began theSafavid era and, under influence culture and art, became a genuine art called Girih tiles; this flourished unprecedentedly Qajar era. The present study aimed identify intercultura...

While some constraints are necessary to the correct performance of liturgy, both nature liturgical language and its wider setting argue for openness. In case language, examples drawn from scripture, formal liturgy hymns suggest that their power derives in part open, poetic character. The multivalent character metaphor can help draw worshipers into dialogue with God. Because all metaphors partia...
