Alcohol ethoxylates surfactants are produced via ethoxylation of fatty alcohol (FA) with ethylene oxide. The source of FA could be either palm kernel oil (PKO) or petrochemicals. The study aimed to compare the potential environmental impacts for PKO-derived FA (PKO-FA) and petrochemicals-derived FA (petro-FA). Cradle-to-gate life cycle assessment has been performed for this purpose because it e...

112 Background: There are no reports in the literature so far, showing the coexisting presence of a lymphoma and a cholesteatoma in the skull base. Our sim was to point up the clinical features of a primary malignant left petro-clival lymphoma presenting with a concomitant petrous cholesteatoma. The patient presented a progressive history of dysartrhia and multiple cranial nerve palsies. Both t...
Closing the structure-function divide is more challenging in the brain than in any other organ (Lichtman and Denk, 2011). For example, in early visual cortex, feedback projections to V1 can be quantified (e.g., Budd, 1998) but the understanding of feedback function is comparatively rudimentary (Muckli and Petro, 2013). Focusing on the function of feedback, we discuss how textbook descriptions m...
