OBJECTIVE To determine the transfer of 2-naphthol (2-NPH) in fullterm human placental tissues. METHODS Six placentas were studied. The ex-vivo dual closed-loop human placental cotyledon perfusion model was used. 2-NPH was added to the perfusate in the maternal compartment. Samples were obtained from the maternal and fetal up to 360 min measuring. RESULTS The mean fetal weight was 2880 ± 304...

The influence of zinc, iron, cobalt, and manganese on submerged cultures of Fusarium moniliforme NRRL 13616 was assessed by measuring dry weight accumulation, fusarin C biosynthesis, and ammonia assimilation. Shake flask cultures were grown in a nitrogen-limited defined medium supplemented with various combinations of metal ions according to partial-factorial experimental designs. Zinc (26 to 3...

We study the interplay of Anderson localization and interaction in a two chain Hubbard ladder allowing for arbitrary ratio of disorder strength to interchain coupling. We obtain three different types of spin gapped localized phases depending on the strength of disorder: a pinned 4kF Charge Density Wave (CDW) for weak disorder, a pinned 2kF CDW π for intermediate disorder and two independently p...

Temperature-dependent ~300–10 K! reflectance measurements were made on h-Mo4O11 and g-Mo4O11 in the conducting b-c plane in the frequency range 30–8000 cm, for light polarized both parallel and perpendicular to the charge density wave ~CDW! direction ~b axis!. The optical conductivity was determined from a Kramers-Kronig analysis of the reflectance. The data clearly show strong suppression of t...

abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...

We suggest that a magnetic-field-induced Peierls instability accounts for the recent experiment of Zhang et al. in which unexpected quantum Hall plateaus were observed at high magnetic fields in graphene on a substrate. This Peierls instability leads to an out-of-plane lattice distortion resulting in a charge density wave (CDW) on sublattices A and B of the graphene honeycomb lattice. We also d...

We study theoretically the low-temperature phases of a two-component atomic Fermi gas with attractive s-wave interactions under conditions of rapid rotation. We find that, in the extreme quantum limit, when all particles occupy the lowest Landau level, the normal state is unstable to the formation of charge density wave (CDW) order. At lower rotation rates, when many Landau levels are occupied,...

The optical conductivity spectra of quasi-one dimensional compounds K0.3Mo1−xWxO3 (x=0, 0.03 and 0.15) have been studied over broad frequencies. While the dc resistivity measurements indicate no sign of CDW transition in heavily W-doped blue bronze, the optical conductivity spectra still show a single particle gap at around 0.2 eV for E parallel to the chain direction. Such impurity effect chal...

Effective motion control could achieve the accurate positioning and fast movement of industrial robotics to improve productivity significantly. Time-optimal trajectory optimization (TO) is a great concern in robotics, which efficiency by providing high-speed reasonable references controllers. In this study, new general time-optimal TO strategy, second-order continuous polynomial interpolation f...

OBJECTIVE To examine the effect of magnesium sulfate (MgSO(4)) on tumor necrosis factor-alpha (TNF-alpha) secretion by preeclamptic placentas. STUDY DESIGN Cotyledons of six, term, normotensive and ten, pre-eclamptic placentas were dually perfused for six hours (6h), with MgSO(4) (6-7 mg %) in the maternal reservoir [normotensive (n = 3); pre-eclamptic (n = 5)], and with control medium (witho...
