Placenta-maternal plasma ratios and fetal-maternal plasma ratios

Placenta-maternal plasma ratios and fetal-maternal plasma ratios for C-13-DHA were significantly higher than those for any other FA.


Twelve hours after oral application of C-13-labeled FAs, relatively stable tracer enrichment was achieved. We found a significantly higher ratio SN-38 cell line of C-13-DHA concentrations in cord plasma than in maternal plasma, which was higher than that for the other studied FAs. C-13-DHA is predominantly esterified into phospholipids and triglycerides in maternal plasma, which may facilitate its placental uptake and transfer. Am J Clin Nutr 2010; 92: 115-22.”
“Three dimensionally structured thin film photovoltaic devices based on interdigitated arrays of microscale electrodes are examined by external quantum efficiency simulations, indicating considerable J(SC) enhancement is possible through elimination of the front contact and window layer required in planar

geometry devices. Electrode parameters including, pitch, width, height, and material are modeled and experimentally probed, demonstrating experimentally and capturing in models dependence on intrinsic material properties and electrode dimensions. In contrast to analogous silicon wafer back contact solar cells where the electrodes are placed on the silicon absorber at the end of processing, in this design the semiconductor is deposited on the electrodes, taking advantage of the thin film processing already required. Electrodeposited CdS/CdTe heterojunction devices approach 1% efficiencies with simulations as well as optical measurements indicating significant potential for improvement. Suboptimal performance is attributed to unintended materials reactions that preclude annealing at the temperatures required for absorber optimization as well RG-7112 ic126 as the Schottky barrier formation on the nonoptimal electrode materials. The test bed structures and absorber synthesis processes are amenable to an array of deposition techniques for fabrication and measurements of three dimensionally structured

semiconductors, contact materials, and photovoltaic devices subject to processing feasibility and materials compatibility. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3561487]“
“Rice straw fiber-high density polyethylene (HDPE) composites were prepared to investigate the effects of rice straw fiber morphology (rice straw refined fiber, rice straw pellet, rice straw strand), fiber content (20 and 40 wt %), and maleic anhydride polyethylene (MAPE) concentration (5 wt %) on the mechanical and thermal properties of the rice straw fiber-HDPE composites in this study. Rice straw refined fiber exhibited more variability in length and width, and have a higher aspect ratio of 16.3. Compared to the composites filled of rice straw pellet, the composites made of the refined fiber and strand had a slightly higher tensile strength and lower tensile elongation at break.
