This Kinetic, Bioavailability, and Metabolism Study of RRR-alpha-Tocopherol in Healthy Adults Suggests Lower Intake Requirements than Previous Estimates

submitted by: jnusda
Kinetic models enable nutrient needs and kinetic behaviors to be quantified and provide mechanistic insights into metabolism. Therefore, we modeled and quantified the kinetics, bioavailability, and metabolism of RRR-alpha-tocopherol in 12 healthy adults. Six men and 6 women, aged 27 +/- 6 y, each ingested 1.81 nmol of 14C-RRR-alpha-tocopherol; each dose had 3.70 kBq of 14C. Complete collections of urine and feces were made over the first 21d from dosing. Serial blood samples were drawn over...

New Perspectives of Energy Storage Materials

submitted by: RASEIBoulder
Summary: Energy storage in the electrochemical form is attractive because of its high efficiency and fast response time. New and improved materials for energy storage are urgently required to make more efficient use of our finite supply of fossil fuels, and to enable the effective use of renewable energy sources. In this seminar, I will discuss a few new perspectives for energy storage materials including new Li intercalation compounds, new Na intercalation compounds and new...

Direct Current Modeling

submitted by: SirZerp
This video was made to test the modeling of electric current with Direct Coulomb Summation on Nvidia GPU's. It is using 1.2 million dipole charges in stacked radial loops to model electric current. The simulations were computed on a GTX 560 over a few days. In general, the video uses Coulomb's law to compute an large 321x321x321 observational cube of data. The dataset is then sent to a ray tracer which produces the images in the video. The background colors show the potential energy...
