Source rock characteristics based on biomarker compositions of crude oils in Japan:

Occurrence and Distribution of Chrysene and its Derivatives in Crude Oils and Source Rock Extracts from Niger Delta, Nigeria

Crude oils and source rocks from the northern and offshore Niger Delta basin, Nigeria, have been characterized by gas chromatography-mass spectrometry in terms of their origin and thermal maturity based on the distribution of chrysene and its derivatives. The crude oils and source rocks were characterized by the dominance of chrysene over benzo[a]anthracene. 3-methylchrysene predominated over o...

Occurrence and Distribution of Pyrene and its Derivatives in Crude Oils and Source Rock Extracts from Niger Delta, Nigeria

Crude oils and source rocks from the Northern and offshore depobelts of the Niger Delta basin, Nigeria have been characterized based on the distribution of pyrene and its derivatives by gas chromatography-mass spectrometry. Moreover, the crude oils have been characterized by the dominance of pyrene over fluoranthene while fluoranthene generally predominated over pyrene in the rock samples. Also...

Antimicrobial characteristics of some herbal Oils on Pseudomonas aeruginosa with special reference to their chemical compositions

Pseudomonas aeruginosa is an important opportunistic pathogen causing widespread infections by numerous virulence factors. Increasing resistance to antibiotics makes the Pseudomonas infections treatment further difficult. The purpose of this study was to evaluate antimicrobial characteristics of essential oils from Matricaria chamomilla, Artemisia persica, Zataria multiflora, Myrtus communis, R...
