Background & Aim:The genus Salvia (commonly known as sage) is a broad genus belonging to the family Lamiaceae. This study is aimed at assessing the essential oil composition and antimicrobial activities of two Salvia species. Experimental: The chemical composition of the essential oils of Salvia officinalis L. and Sa...

Soil salt content is a key factor that determines soil chemical quality together with soil reaction, charge properties and nutrient reserves (Lal et al., 1999). An adequate salt supply is essential for an optimum development of photosynthetic mechanism and other biochemical processes in plants (Sitte et al., 1994). Soil salt content constitutes an environmental problem when salt accumulation ge...

Since the devastating attacks of September 11, 2001 there have been numerous discussions on the issue of terrorism and terrorist networks, such as al Qaeda, within the media and the intelligence community. At times these discussions have created an image of the terrorist phenomenon as one of a monolithic and unstoppable menace continuing to spread around the world unabated. Lost in these discus...

Nature which consists of so many variabilities of living components of the environment possesses useful, harmful and inactive chemical constituents. The classification based on these chemical constituents is known as chemotaxonomy. All the living components of the environment produce secondary metabolites that are derived from primary metabolites. The chemical structure of the secondary metabol...

The yield of radical pair reactions is influenced by magnetic fields well beyond the levels expected from energy considerations. This dependence can be traced back to the microscopic dynamics of electron spins and constitutes the basis of chemical compasses. Here we propose a new experimental approach based on molecular photoswitches to achieve additional control on the chemical reaction and al...
