Fixed oil of O. basilicum was found to possess significant antiinflammatory activity against carrageenan and different other mediator-induced paw edema in rats. Significant inhibitory effect was also observed in castor oil-induced diarrhoea in rats. It also inhibited arachidonic acid- and leukotriene-induced paw edema. The results of antiinflammatory activity of O. basilicum support the dual in...

The fruits contain tannins (2), volatile oil (6, 7), various organic acids (2), anthocyanins (6) and fixed oil (6). Either the whole fruit or only the pericarp is used as a condiment in Turkey and called “Sumak” (2, 9). The composition of the essential oils prepared from the fruit, leaves and branch barks of R. coriaria has been reported on the same Anatolian material (7). The anatomical charac...

Permeability reduction in oil reservoirs during primary oil recovery and using the enhanced oil recovery methods are complicated problem which most of the oil field in worlds has encountered. In this work, a modified model based on four phase black oil model (oil, water, gas, and asphaltene) was developed to account permeability reduction during CO2 flooding in cylindrical coordinates around a ...

Nanodroplets on a solid surface (i.e., surface nanodroplets) have practical implications for high-throughput chemical and biological analysis, lubrications, laboratory-on-chip devices, and near-field imaging techniques. Oil nanodroplets can be produced on a solid-liquid interface in a simple step of solvent exchange in which a good solvent of oil is displaced by a poor solvent. In this work, we...

Isolation of volatile and fixed oils from dried berries of Laurus nobilis L. from Tunisia have been obtained by supercritical fractioned extraction with carbon dioxide. Extraction experiments were carried out at a temperature of 40 degrees C and pressures of 90 and 250 bar. The extraction step performed at 90 bar produced a volatile fraction mainly composed of (E)-beta-ocimene (20.9%), 1,8-cine...

Activity recognition has gained a lot of interest in recent years due to its potential and usefulness for context-aware wearable computing. Most approaches for activity recognition focus on repetitive or long time patterns within the data. There is high interest in recognizing very short activities, such as pushing and pulling an oil stick or opening an oil container as sub-tasks of checking th...

Oil producers are going through a hard period. They have a number of real options at their disposal. This paper addresses the valuation of two of them: the option to delay investment and the option to abandon a producing field. A prerequisite for this is to determine the value of a producing well. For this purpose we draw on a stochastic model of oil price with three risk factors: spot price, l...

Pyrolysis of Alcea pallida stems was performed in a fixed-bed tubular reactor with and without catalyst at three different temperatures. The effects of pyrolysis parameters including temperature and catalyst on the product yields were investigated. It was found that higher temperature resulted in lower liquid (bio-oil) and solid (bio-char) yields and higher gas yields. Catalysts had different e...

Context: Broussonetia papyrifera (L.) Vent. (Moraceae), a traditional Chinese medicinal herb, has been extensively applied for many years to treat various diseases. Its fruits (Fructus Broussonetiae) have been commonly used as an important tonic for the treatment of age-related disorders with long history; recent research has proved that it contains 32% to 35% fixed oils. The fixed oil is compo...
