This paper deals with the application of steam to enhance the recovery from petroleum reservoirs. We formulate a mathematical and numerical model that simulates coinjection of volatile oil with steam into a porous rock in a one-dimensional setting. We utilize the mathematical theory of conservation laws to validate the numerical simulations. This combined numerical and analytical approach revea...

Volatile oil of Psidium guajava leaves obtained by steam distillation was given orally to study its effects on the exudation and proliferative phases of the inflammatory reaction, using technique of carragenin induced paw edema and cotton pellets in male albino rats. The anti inflammatory activity as compared with ketorolac tromethamine. In carragenin induced edemas,. 0.8ml/kg of the volatile o...

The chemical composition of the extracted fixed oil (total fatty acid composition) and volatile oil of Nigella sativa L. seeds grown in Iran were determined by GC and GC/MS. Eight fatty acids (99.5%) and thirty-two compounds (86.7%) have been identified in the fixed and volatile oils, respectively. The main fatty acids of the fixed oil were linoleic acid (55.6%), oleic acid (23.4%), and palmiti...

Among all the aromatic compounds phenol is the major constituent of soil contaminated form many industries. Toxicity of phenol is well recognized for human as well as environment. In future, microbial system is the potential tool to deal with environmental pollutants like phenol. In the present study, an aerobic bacterial culture was isolated from oil contaminated soil by enrichment technique a...

Morphological, chemical and genetic differences of 12 tree basil (Ocimum gratissimum L.) accessions were studied to determine whether volatile oils and flavonoids can be used as taxonomical markers and to examine the relationship between RAPDs to these chemical markers. Eugenol, thymol, and geraniol were the major volatile oil constituents found in Ocimum gratissimum. Xantomicrol and cirsimarit...

The lower eyelid skin will retain its pigmentation and wrinkles after a routine lower blepharoplasty. Phenol peeling with croton oil combinations produces a complementary lightening of the skin and an improvement of the wrinkling. Deep peeling with phenol and croton oil has been controversial because of the hypo-pigmentation that generally results. This report explains the technique used by the...

In Present study the antinociceptive and the gastroprotective effects of orally administered or inhaled Thevetia peruviana Pers. K. (Schum) (Oleander) volatile oil, and its principal constituents linalool and 1,8-cineole were evaluated in mice. Either when orally administered (100μl/kg) or inhaled for 60 min Thevetia peruviana volatile oil significantly reduced the acetic acid-writhing response...

The object of this study is the flowers of Kazakhstan species of “AkMai” safflower, collected in the flowering stage in Southern Kazakhstan. Volatile oil was carry out to study the component composition of Kazakhstan “AkMai” safflower flowers. The composition of the volatile oil obtained from the dried flowers of Carthamus tinctorius L. growing in Kazakhstan. Pale yellow oily extracts were obta...

BACKGROUND Alperujo is the paste generated from the two-phase extraction system of olive oil. This wet pomace must be stored for several months and, during this period, the formation of 4-ethyphenol provokes a strong off-odour. The aim of this work was to identify the microorganisms able to produce this volatile phenol. RESULTS Yeast and bacterial strains were isolated from stored alperujo an...
