BACKGROUND The obesity pandemic is associated with multiple major health concerns. In addition to diet and lifestyle, there is increasing evidence that environmental exposures to chemicals known as obesogens also may promote obesity. OBJECTIVES We investigated the massive environmental contamination resulting from the Deepwater Horizon (DWH) oil spill, including the use of the oil dispersant ...
BACKGROUND Earwax is a common problem in general practice. The incidence of complaints owing to earwax in general practice in the Netherlands is 39.3 per 1000 patients. AIM To determine the feasibility of a strategy using water as a quick dispersant for persistent earwax, compared with the usual strategy using oil as a dispersant for three days in a general practice setting. DESIGN OF STUDY...
Anionic polyurethane dispersants APUDs were used as dispersing agents in formulation of waterborne paints. The APUDs were synthesized by three steps. In the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diisocyanate IPDI, dimethylol propionic acid DMPA in presence of acetone as solvent and dibutyltin dilaurate DBTDL as catalyst. Then, carboxylic polyure...
Aerial Dispersant application has changed platform in recent years with the introduction of worlds first jet platform; a Boeing 727 complete TERSUS dispersant delivery system. During development this platform, stringent measures were imposed to comply aviation standards, necessary obtain approval from authorities operate. Airframe icing occurs when ambient temperature is low enough allow water ...
The aim of the present research is to convert bioinert surface of NiTi to bioactive and biocompatible surface. In order to develop a bioactive and corrosion resistant film on NiTi, electrophoretic deposition process was done and TiO2 particles were deposited on the NiTi surface. Suspensions including TiO2 particles were prepared using a mixture of acetone and n-butanol (0%, 30%, 60%, 80% and 10...
