In the movie "Grease," John Travolta may not have been referring to fries, donuts, and pizza when he sang "You're the One That I Want," but it's not difficult to understand why greasy foods hold a special place on our taste buds. Although eating foods that are high in cholesterol [2] may contribute to gallbladder problems, not all greasy and oily foods are high in cholesterol. And for some good...

OBJECTIVE To evaluate the bioavailability of vitamin D in capsules as compared with oily drops in nuns living in a closed community with very low sun exposure. METHODS A randomized, 2 x 2 crossover, open clinical trial was conducted, with 18 nuns aged between 20 and 75 years. Samples were collected in the fasting state and at 4, 8, 12 and 24 hours following the administration of capsules and ...

Local full Mueller matrix measurements in the Fourier plane of a microscope lens were used to determine the internal anisotropic ordering in periodic linear arrays of smectic liquid crystal defects, known as 'oily streaks'. We propose a single microstructure-dependent model taking into account the anisotropic dielectric function of the liquid crystal that reproduces the smectic layers orientati...

Society must move towards an economy in which sustainability is its main driving force. A sustainable solution to avoid sending waste landfill, the consumption of raw materials and, therefore, depletion natural resources, reuse or recycling waste. Here, pavement engineering has great potential, as can be used for manufacture bituminous mixes. In particular, one these residues Marpol, generated ...

• Waste cooking oil was considered as feedstock for biodiesel production. Kinetic data were derived from actual WCO samples avoiding model components. Aluminum chloride hexahydrate is a promizing catalyst the esterification step. Reactive distillation with alkali used transesterification. In this work, novel method proposed conversion of waste into biodiesel. A two-step approach based on pretre...

Ultrasonic technology is a promising tool for washing oily sludge to recover oil. In this study, the influence of ultrasonic conditions on the removal of different oil components from oily sludge was investigated to optimize ultrasonic washing technology. Among the three frequencies (25, 50 and 100 kHz) applied, ultrasonic washing at 25 kHz exhibited the best performance in terms of oil extract...
