The effect of the surfactant, alpha-[4-(1,1,3,3-tetramethylbutyl) phenyl]-omega-hydroxypolyoxy-1,2-ethanediyl, on the adsolubilization of cholesterol and/or dotriacontane as model compounds of the epicuticular wax of mature tomato (Lycopersicon esculentum Mill.) fruit was investigated. Cholesterol as a model compound of such triterpenols as alpha- and beta-amyrins was solubilized in a concentra...

A better knowledge of the transport and thermodynamic properties for the refrigerant+lubricant system is required to properly design the refrigeration circuit. This is essential also to develop proper models able to predict the behavior of the mixture refrigerant+lubricant depending on the working conditions. However, the experimental data available in literature are insufficient to build dedic...

Different blends of a linear polypropylene (L-PP), long-chain branched (LCB-PP), and polyolefin elastomer (POE) are prepared foamed using core-back injection molding. The objective is to analyze the use POE LCB-PP as complementary strategies improve cellular polymers’ impact response. parameters then studied in molded plaques understand samples’ mechanical behavior. Parameters such interfacial ...

BACKGROUND There is a need to better understand the perceived experiences of workers in green buildings as the literature to this point has been mixed. OBJECTIVES To re-evaluate occupant experiences within a LEED platinum building and investigate current experiences in general. METHODS An online post occupancy evaluation (POE) survey of 62 occupants of LEED Platinum building on a US college...
