The materials used in this study include HDPE (HD100 from M. Holland Company), PP (Polypropylene 3281 from Total Petrochemicals USA, Inc.) and HIPS (IS200 from M. Holland Company). Each polymer was then compounded with SureFlo at two different levels, 5 and 10%. A Q-500 thermogravemetric analyzer (TGA) was used for the study. In each experiment, the sample (typical size ~ 10 mg) was heated from...

Several fatty acid alkyl esters were subjected to accelerated methods of oxidation, including EN 14112 (Rancimat method) and pressurized differential scanning calorimetry (PDSC). Structural trends elucidated from both methods that improved oxidative stability included decreasing the number of double bonds, introduction of trans as opposed to cis unsaturation, location of unsaturation closer to ...

Fatty acid methyl esters prepared from canola, palm, soybean, and sunflower oils by homogenous basecatalyzed methanolysis were stored for 12 months at three constant temperatures ( 15, 22, and 40 C) and properties such as oxidative stability, acid value, kinematic viscosity, low temperature operability, and iodine value were periodically measured. Oxidative stability was significantly reduced u...

Flavor and oxidative stabilities of a northerngrown sunflower seed oil were investigated. Taste panel and oxidative evaluations were made on alkalirefined, deodorized, unbleached samples treated with commercial antioxidant mixtures, phenolic antioxidants, metal scavengers and added trace metals. Similar evaluations were conducted on a sample of the same oil after bleaching. Commercial antioxida...

An interaction form is an abstract model of interaction based on a description of power distribution among agents over alternatives. A solution known as the settlement set is defined at any preference profile. Necessary and sufficient conditions for stability, that is the existence of settlements, are established. A Stability Index that plays a role similar to that of the Nakamura Number is def...

Oxidative stability of chia seed oil enriched with oregano (Origanum vulgare L.) and yarrow (Achillea millefolium) extracts at different concentrations (600, 1200, 1800 ppm) was evaluated under accelerated oxidation conditions for 5 days. The total phenolic compounds antioxidant activity extract were higher than the extract. With decreasing increasing time, oxidative decreased significantly ( <...

We have developed a 3-D Eulerian hydrodynamics code to model sources of gravitational radiation. The code is written in cylindrical coordinates (̟, z, φ) and has moving grids in the ̟ and z-directions. We use Newtonian gravity and calculate the gravitational radiation in the quadrupole approximation. This code has been tested on a variety of problems to verify its accuracy and stability, and the ...
