Introduction: In this study, the chemical composition and antimicrobial activity of essential oil of Ziziphora clinopodiodes and its potential application as a natural preservative in reducing the indigenous microbial population of hamburger were investigated. Method: Essential oil of Ziziphora clinopodiodes cultivated in Iran was obtained by Hydro-distillation method (HDM). Chemical compositio...

Background. Eryngium foetidum L. grows in the wet zone of Sri Lanka. Despite fact that this plant is widely used for healthcare purposes and as a culinary spice tropical regions, limited scientific research has been available. This study aimed to investigate phytoconstituents, essential oil (EO), antioxidative potential (AP), proximate composition, well find suitable extracting solvent extract ...

Phase-change materials (PCMs) utilize the latent heat absorbed and emitted during their phase change are used in many thermal applications. Studies have investigated melting process of PCMs filled a rectangular cavity determined that closed is considerably affected by natural convection melted PCMs. Therefore, detailed understanding heat-transfer mechanism governs required to maximize rate, whi...

Methane clumped isotope analysis is a tool used to constrain the formation or equilibration temperatures of methane, differentiate methane thermogenic, microbial ‘abiotic’ origins. Geothermometry applications are based on temperature dependence relative abundances multiply-substituted isotopologues in thermodynamic equilibrium, whereas assignments biogenicity ‘abiogenicity’ rely kinetic effects...

Background and objectives: Garden lettuce, Lactuca sativa L. (Asteraceae), is an herbaceous plant cultivated in different parts of Iran including Isfahan. In Iranian traditional medicine, it is classified as a medicinal food because it is nutritive and has therapeutic effects. As the therapeutic effects of the plant parts may be related to some volatile active constitu...

Self-adapting fixed endpoint configurational-bias Monte Carlo simulations in the Gibbs ensemble were carried out to determine the vapour–liquid coexistence curves of cyclic alkanes from c-pentane to c-octadecane. In general, the critical temperatures and densities of the cyclic alkanes are substantially higher than those of their linear counterparts. Furthermore, the simulation data point to a ...
