An attempt has been made to show the difference in the penetrability of coconut oil and mineral oil in human hair. We have used secondary ion mass spectrometry (SIMS) in combination with a time-of-flight (TOF) mass spectrometer. Characteristic ions formed by the pure components when bombarded with gallium ions have been identified with their m/z values. The distribution of the ion, characterist...

This paper concerns the sensitivity of artists’ oil paints to organic solvents. Specifically, it examines the respective capacities of single organic solvents and mixtures of solvents to cause swelling as a consequence of sorption into the paint and solvency action thereupon. The swelling power of a solvent is essentially an indicator of its relative strength in terms of action on the original ...

in this paper, the role of molecular diffusion in mobilization of waterflood residual oil is examined. a moving mesh method is applied to solve the moving interface problem of residual oil blobs swelling by co2 diffusion through a blocking water phase. the results of this modeling are compared with experimental results of a 2d glass micromodel experiment. although, the solution method is applie...

UNLABELLED Silicone oil is used for complicated retinal detachment, but it can be associated with relevant side effects. We report a 6-year-old South American female admitted to our hospital with steroid-resistant Fisher-Evans syndrome. She also had developed a retinal detachment, managed with intravitreal oil injection. During treatment for Fisher-Evans syndrome, she progressively developed re...

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

Alginate based mineral oil entrapped emulsion gel (MOEG) buoyant beads of domperidone were prepared by emulsion gelation technique. The prepared beads were evaluated for particle size, surface morphology, buoyancy, actual drug content and entrapment efficiency. Effect of different oils (castor oil, olive oil and linseed oil) and oil concentrations (10%, 15% and 20%, w/w) on uniformity, homogene...

Clays are of paramount importance for soil stability, but also in applications ranging from oil recovery to composites and hydrogels. Generically, clays are divided into two subclasses: macroscopically swelling, 'active' clays that have the capacity for taking up large amounts of water to form stable gels, and 'passive' or non-swelling clays; the former stabilize soils whereas the latter are kn...

A 30-year-old male, who underwent previous pars plana vitrectomy and silicone oil tamponade due to endogenous endophthalmitis originated from Klebsiella liver abscess, was referred for evisceration. At 2 months after vitrectomy with silicon oil tamponade, conjunctival chemosis and ocular pain were aggravated. Diffuse eyelid swelling and large subconjunctival mass with lipid droplets were noted....
