Additional incorporation of the nanofillers in 2.5 wt % enhanced the stiffness and strength PHA-739358 molecular weight of the PA-6/HNBR blend but reduced its ductility. The fracture toughness

of the ternary nanocomposites was between those of PA-6 and PA-6/HNBR, whereas their fracture energy fairly agreed with that of the parent PA-6. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 123: 897-902, 2012″
“Background The importance of unmetabolized folic acid in maternal and letal blood is not known

Objective We investigated total folate tetrahydrofolate (THF) 5 methyltetrahydrofolate (5 MTHF) formyl THF 5 10 methenyITHF and folic acid concentrations in women and in umbilical cord blood at delivery

Design The study included 87 pregnant women and

29 cord blood Ganetespib research buy samples including 24 mother Infant pairs We measured serum concentrations of folate forms by using ultraperformance liquid chromatography tandem mass spectrometry

Results Pregnant women who received 400 mu g folic acid daily (n = 25) had higher total folate (P = 0 041) 5 MTHF (P = 0 049) and formyl THF (P < 0 001) concentrations and slightly higher THF (P = 0 093) concentrations than did nonsupplemented pregnant women (n = 61) We measured folic acid concentrations >0 20 nmol/L in 38 (44%) pregnant women and in 55% of the cord serum samples but these measurements were not explained by maternal supplement use Concentrations of folic acid were nonsignificantly higher in cord blood from supplemented women than in cord blood from nonsupplemented women (P = 0 154) Proportions of folic acid to total folate

in cord serum did not differ according to maternal supplement usage (0 54% compared with 0 43% in supplemented and nonsupplemented women respectively) Concentrations of folic acid did not differ between maternal and cord serum However folic acid constituted a significantly lower proportion of total folate in cord serum than in maternal serum

Conclusions We detected unmetabolized folic acid in more than one half of cord blood samples Folic acid (400 mu g/d) supplied during pregnancy is not likely to accumulate in the fetus in contrast to 5 MTHF and THF which accumulate in the fetus Am J Clin Nutr 10058-F4 2010 92 1416-22″
“A new procedure of determining the time resolved capacitance of a plasma actuator during operation is introduced, representing a simple diagnostic tool that provides insight into the phenomenological behavior of plasma actuators. The procedure is demonstrated by presenting example correlations between consumed electrical energy, size of the plasma region, and the operating voltage. It is shown that the capacitance of a plasma actuator is considerably increased by the presence of the plasma; hence a system that has previously been impedance matched can be considerably de-tuned when varying the operating voltage of the actuator. Such information is fundamental for any attempts to increase the energy efficiency of plasma-actuator systems.
