Oily sludge (OS) degrading potentials of single and consortium autochthonous bacterial population was carried out using standard analytical procedures. Three species; Pseudomonas aeruginosa, Bacillus cibi subtilis were associated with the OS. The isolates exhibited varying OS utilizing biosurfactant producing potentials. P. aeruginosa best utilizer while B. producer (emulsification index 15.6%)...

Produced water separated from oil is usually returned to the environment and could permeate through the water table. If such water is contaminated with radioactive substances, it could create a definite threat to the water supply, especially in arid regions where ground water and overhead streams are sources of potable water. Low-level radioactive contamination of oily sludge is equally hazardo...

Heterogeneous oily waste from an old dumping site was composted in three windrows constructed from different proportions of waste, sewage sludge, and bark. The objectives of this pilot study were to examine the usefulness of composting as a treatment method for this particular waste and to study decontamination in the composting process by using a battery of toxicity tests. Five samples from th...

This paper reports on hydrocarbon-degrading microbial consortia immobilized in biofilms on gravel particles in the intertidal zone of the Arabian Gulf coast. These microorganisms contribute to the self-cleaning of the coasts and, in addition, could potentially be used for cleaning oily industrial waste before its disposal in the open environment. Each gravel particle was found coated with about...

INTRODUCTION Developed using focus groups, the Oily Skin Self Assessment Scale (OSSAS) and Oily Skin Impact Scale (OSIS) are patient-reported outcome measures of oily facial skin. OBJECTIVE The aim of this study was to finalize the item-scale structure of the instruments and perform psychometric validation in adults with self-reported oily facial skin. METHODS The OSSAS and OSIS were admini...

OBJECTIVE To develop the content for two new patient reported outcome (PRO) measures to: a) assess the severity of symptoms; and b) the impact of facial skin oiliness on emotional wellbeing using qualitative data from face to face, and internet focus groups in Germany and the US. METHODS Using input from initial treatment satisfaction focus groups (n = 42), a review of relevant literature and...

In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...

The effective use of aqueous and oily pilocarpine was studied in 19 glaucomatous eyes. The aqueous drops were used 4 times a day while the oily drops were used only twice. It was found that the oily drops were better than the aqueous drops in lowering the mean intraocular pressure and the maximum pressure reached during the day. no statistically significant difference was found between the 2 pi...
