Moisture contents of Hom Nil rice flour for fixed extrusion conditions, 120 and 80°C of die and transition zone temperature of barrel, respectively and 250 rpm screw speed, were varied at 13, 15 and 17%. Physicochemical and sensory properties of the product were evaluated. The 15% moisture content of rice flour caused the optimum properties of extrudate. The effects of diezone barrel temperatur...

Lemongrass oil (Cymbopogon citratus) is an effective repellent against mosquitoes (Diptera: Culicidae) and house flies (Diptera: Muscidae). In this study, its effectiveness was assessed on stable flies (Diptera: Muscidae) in laboratory conditions. First, we demonstrated that lemongrass oil is an active substance for antennal olfactory receptor cells of Stomoxys calcitrans as indicated by a sign...

The indoor comprehensive analysis of core saturation airtight coring wells is an important part well logging interpretation. According to the data, geological reserves can be accurately calculated, and remaining oil water-flooded zone in later stage production evaluated. Due influence many factors process experiment process, sum water usually not equal 100%. At present, conventional correction ...

Reservoirs are manmade habitats, intermediate between rivers and lakes, presenting distinct hydrological and morphometric characteristics, with differential mean water residence time. They also present proper vertical and horizontal organisations, and their evolution depends on several variables acting on different special and temporal scales. The water quality evolution of the Itaipu Reservoir...

Abstract Water is one of the most significant causes lubrication failure. There little research on direct observation impact water properties. In this study, influence oil replenishment under different elastohydrodynamic (EHD) lubricating conditions evaluated using optical interferometry and infrared microscopy, a dimensionless criterion when influences film thickness proposed. Evidence shows t...

We use dissipative particle dynamics (DPD) and molecular models to simulate interacting oil/water/surfactant interfaces. The system comprises sections of two emulsion droplets separated by a film. The film is in equilibrium with a continuous phase, in analogy with the surface force apparatus. This is achieved by combining DPD with a Monte Carlo scheme to simulate a muVT ensemble. The setup enab...

An unprecedented volume of crude oil was burned during the Deepwater Horizon oil spill response, with an estimated 220,000-310,000 bbl of surface oil consumed by in-situ burning over a ten-week period in 2010. Most of the resultant burn residue from these large-scale operations sank in the relatively deep waters of the Gulf of Mexico. However, in late 2010, the deep water royal red shrimp fishe...

Babassu oil extraction is the main income source in nut breakers communities in northeast of Brazil. Among these communities, babassu oil is used for cooking but also medically to treat skin wounds and inflammation, and vulvovaginitis. This study aimed to evaluate the anti-inflammatory activity of babassu oil and develop a microemulsion system with babassu oil for topical delivery. Topical anti...

In the present work specific adsorption phenomena of metal ions at the water –oil interface are studied. Bicontinuous microemulsions were chosen as a model system because of their high specific surface between water and oil phases. Mixing an extremely hydrophobic extractant considered here as the co-surfactant with an extremely hydrophilic sugar surfactant we succeed to formulate microemulsion ...

Laboratory and numerical experiments were conducted to investigate the evolution of soil water evaporation during a continuous drying event. Simulated soil water contents and temperatures by the calibrated model well reproduced measured values at different depths. Results show that the evaporative drying process could be divided into three stages, beginning with a relatively high evaporation ra...
