Rosmarinus officinalis L. is a perennial herb that belongs to the Lamiaceae family. It is used as a food flavouring agent, and well known medicinally for its powerful antimutagenic, antibacterial and chemopreventive properties. The most applicable method for extraction of essential oil is water distillation (WD) and steam distillation (SD). It is a traditional technique which is used in most in...

Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rota...

Thermal oil recovery is a special technique belonging to Enhanced Oil Recovery (EOR) methods and includes steam flooding, cyclic stimulation, in-situ combustion (fire flooding) applied especially in the heavy reservoirs. Starting 1970 (ISC) process has been successfully continuously Suplacu de Barcau field, currently this one representing most important reservoir operated by ISC world. field sh...

Steam reforming of methanol is one of the promising processes for on-board hydrogen production used in fuel cell applications. Due to the time and energy consuming issues associated with conventional synthesis methods, in this paper a quick, facile, and effective microwave-assisted solution combustion method was applied for fabrication of copper-based nanocatalysts to convert methanol to hydrog...

Abstract The instability at the interface between two parallel flows of immiscible liquids through a uniform planar pore is studied by using linear stability analysis. A characteristic equation determines growth rate versus wavenumber, and conditions are determined. governed dimensionless group relating ratio gravity to interfacial tension. Interfacial tension has stabilizing effect resisting d...
