This paper deals with the theoretical investigation of the thermal instability of a thin layer of electrically conducting micropolar rotating fluid, heated from below in the presence of uniform vertical magnetic field in porous medium. A dispersion relation is obtained for a flat fluid layer, contained between two free boundaries using a linear stability analysis theory, and normal mode analysi...

conclusions the results presented herein provided insight into a possible explanation for the modes of action of essential oils on l. monocytogenes. the outcome of the present study may aid the food industry in locating the most promising potential anti-listerial agents from edible seaweed sources to control l. monocytogenes and also in facilitating their application in food processing and pres...

Fungi of the genus Fusarium are well known plant pathogens, cause several vascular diseases and are producers of toxins. In vitro assays evaluated the effects of Neem (Azadirachta indica) oil on the diameter of colonies, dry weight, spore production, spore viability and production of Fusaric Acid toxin on Fusarium oxysporum f. sp. medicagenis and Fusarium subglutinans isolates. Effects of Neem ...

Background: Hydatid disease is characterized by long-term growth of hydatid cysts in the human. The glycan antigens have an important role in the immunology of hydatid cyst. In this study immunological reaction of host sera to different glycan antigens of the cyst, has been investigated. Methods: The antibody responses were tested to glycoprotein and glycolipid of the laminated layer (LL), c...

Numerical experimentation is an attractive complement to physical measurement of rock properties. In such experiments, a physical process is simulated in a pore space and then the corresponding property is calculated. For example, a simulation of viscous fluid flow through pores provides permeability. Many authors have used pore-scale numerical methods, such as Lattice-Boltzmann and network mod...

The aim of present study was to enhance topical permeation of clotrimazole gel preparation by using various permeability enhancers such as coconut oil, pistachio oil and sodium lauryl sulphate (SLS). Clotrimazole gel preparations were prepared and optimized by using three factor, five level central composite design. A second-order polynomial equation was generated in order to estimate the effec...

The hydrogen permeability of bulk tantalum and tantalum coated with thin films of palladium was measured at temperatures from 623 to 1173 K and hydrogen partial pressures from 0.1 to 2.6 MPa in a flowing gas system. Palladium coatings were deposited by both electroless plating (1–2 m thick Pd layer) and cold plasma-discharge sputtering with two different thicknesses, 0.04 or 1.2 m. All samples ...

In this work, the effect of presence of the sodium tripolyphosphate (STPP), as an inorganic salt, on improving the performance of polyamide (PA) thin layer membranes has been studied. Characterization analyses confirmed the presence of the salt on the whole surface structure of the thin layer. Different salt loadings resulted in different fluxes and Cu (II) rejections. The thin layer containing...

Abstract Availability of gases at the field level makes attractive to water-alternating-gas (WAG) process for low viscosity and light oils carbonate reservoir. However, impact reservoir heterogeneity on WAG performance is crucial before application. In general, ramp carbonates have due variation permeability porosity. significantly affected by variations. This article investigates merits demeri...
