The oil-absorbing resins were used repeatedly through the extraction of ethanol. The experiment results show little effect on the oil-absorption properties. The oil-absorption rate constant was evaluated for diesel, and the oil-absorbing

process obeyed the first-order kinetics equation. (C) 2009 Wiley Periodicals, Inc. I Appl Polym Sci 115: 3321-3325, 2010″
“Organotin 3-Methyladenine compounds are commonly used in industrial and agriculture. It causes toxic effects on skin, eyes, respiratory system, gastrointestinal system, and nervous system. After cleaning a di-methyl tin tank, 43-year-old man showed a dizziness, disorientation, visual hallucination, and agitation. Through a measurement by liquid chromatography and inductively coupled

plasma-mass selleck kinase inhibitor spectrometry, di-methyl tin and tri-methyl tin was detected. Although magnetic resonance (MR) image 3 days after exposure showed no abnormal signal intensity, follow-up MR images 15 days after exposure revealed abnormal extensive signal intensities in the white matter that was not ever coincident with previous reports. It was hardly explainable that previous abnormal signal intensities of MR image nearly disappeared 4 months later. We present a case of a patient who developed acute toxic leukoencephalopathy from an acute inhalational Selleck Liproxstatin-1 exposure to methyl tin with sequential MR images showing an involvement of white matter that was not ever reported.”
“Morphologies of modified starches prepared using different methods were examined by scanning electron microscopy (SEM). These SEM micrographs provide the following results. To begin with, starch granules underwent a series of changes which resulted in the morphology of modified starch quite different from the native starch with different the methods during the process of modification. For example, hollows emerge on the granules of maltodextrin with low value of dextrose equivalent (DE) prepared by means of spray-drying,

but they fell to pieces with the increasing value of DE. The granules of pregelatinized starches manufactured with extrusion technology also showed irregular stone shapes and holes within them while those produced by means of drum-drying presented irregular laminar structure. Furthermore, the granules of granulated cold water soluble (GCWS) starch obtained from alcoholic-alkaline treatment had indented appearance and larger volume than those of the original native granules. The conclusion can be safely drawn that the granule structure of slight modified starches did not change but the surface of the granule was porous. (C) 2009 Elsevier Ltd. All rights reserved.
