salvia is a valuable medicinal and aromatic genus belongs to the lamiaceae family. in this study, morphological traits and essential oil content were used for the estimate of variability and to determine the relationship among different species of salvia including s. syriaca (5 ecotypes), s. virgate (8 ecotypes), s. reuterana (6 ecotypes) and s. multicaulis (6 ecotypes) collected from the south...

1 Acknowledgements I wanted to thank my reader Professor Lisa Meulbroek for all that she has taught me about financial economics as well as her help on this paper. I would like to thank my mom and dad for the guidance and support they have shown me over my years. And lastly but certainly not least I want to thank my two little sisters, Amelia and Colleen, for being the best sisters I could ever...

Selected microbial parameters were monitored in sediments from a pristine and an oil-field salt marsh. Although numbers of hydrocarbonoclastic bacteria and fungi were significantly greater in the oil field, the values did not show a strong correlation with levels of hydrocarbons (r = 0.43 and r = 0.49, respectively). However, a high correlation was noted between ratios of hydrocarbonoclastic an...

The study has been carried out with two broad objectives – to observe the effect of crude oil contamination on consolidation properties of soil and to predict the change in the properties in the form of mathematical correlation. The properties studied here are co efficient of compression (Cv) and compression index (Cc). Four types of naturally available soil (CH, CL, CI and SC) collected from d...

We consider numerical solutions of the Darcy and Buckley-Leverett equations for ow in porous media. These solutions depend on the geology of the porous media, which is given here as a realization of a random eld to describe the reservoir permeability. We measure the solution error as the diierence between the oil production rates (oil cut) for ne grid and upscaled coarse grid solutions of the e...

The analysis of products’ price behaviour continues to be an important empirical issue. This study contributes to the current literature on price dynamics of products by examining for the presence of chaos and non-linear dynamics in daily oil products for the Rotterdam and Mediterranean petroleum markets. Previous studies using only one invariant, such as the correlation dimension may not effec...

in this study, antioxidant activity of kolkhung skin oil, baneh skin oil and seasame oil were compared. the ratio between polyunsaturated to saturated fatty acids (pufa/sfa) of kolkhung skin oil, bane skin oil and seasame seed oil were 0.52, 0.26 and 3.06, respectively. total phenolic contents of kolkhung skin oil, bane skin oil and seasame seed oil were 99.67, 645.73 and 81.72 mg/kg, respectiv...
