For implementation&#10 of the free surface boundary condition, a new subroutine has been introduced to an existing steady 3-D body fitted code. This code was previously written for steady flow simulation in closed ducts. The algorithm used in this subroutine reduces the instability problem according to the free surface wave generation. For code validation, it was applied to two different open c...

Background: Despite the medicinal importance of Balanites aegyptiaca (L.) Del, Stevia rebaudiana (Bert.) Bertoni, Tylophora indica (Burm.f.) Merrill and Cassia sophera (Linn.), the antimicrobial potential of these plants has not been explored extensively, especially those of Cassia sophera. Methods: Both aqueous and alcoholic extracts of various parts of respective plants, and their in vitro ra...

The potential of three submerged aquatic plant species (Cabomba piauhyensis, Egeria densa, and Hydrilla verticillata) to be used for As, Al, and Zn phytoremediation was tested. The plants were exposed for 14 days under hydroponic conditions to mine waste water effluents in order to assess the suitability of the aquatic plants to remediate elevated multi-metals concentrations in mine waste water...

turfgrasses are usually important groundcover plants in many landscapes. they occupy the lowest surface of the landscape, close to pollutant particles. so, they can be an attractive option for environmental remediation. today, high concentrations of hazardous chemicals such as lead are among the most serious environmental problems. in vitro selection of turfgrass accumulator or tolerant of toxi...

BACKGROUND Over the past two decades, there has been a growing trend in using oral hygienic products originating from natural resources such as essential oils (EOs) and plant extracts. Seven aromatic plants used in this study are among popular traditional Iranian medicinal plants with potential application in modern medicine as anti-oral infectious diseases. OBJECTIVES This study was conducte...
