Different solvent extracts of a red algae, Hypnea flagelliformis,and two brown algae, Cystoseira myrica and Sargassum boveanum, collected from the Persian Gulf coast were subjected to different bioassays including: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (TLC)-bioautography, agar disc diffusion (ADD) ...

Accurate functional measurement in cardiovascular diseases is important as inaccuracy may compromise diagnostic decisions. Cardiac function can be assessed using displacement encoding with stimulated echoes, resulting in three signal components. The free induction decay (FID), arising from spins undergoing T(1) -relaxation, is not displacement encoded and impairs the displacement acquired. Tech...

The parameters in a nuclear magnetic resonance (NMR) free induction decay (FID) signal contain information that is useful in magnetic field measurement, magnetic resonance sounding (MRS) and other related applications. A real time sampled FID signal is well modeled as a finite mixture of exponential sequences plus noise. We propose to use the Hilbert-Huang Transform (HHT) for noise reduction an...

In this study, Iran crude oil samples (K, L) were separated on the basis of solubility and polarity, resulting in saturates, aromatics, resins, and asphaltenes fractions. The fractions were analyzed by traditional open column chromatography, thin layer chromatography-Flame ionization detector in an Itroscan instrument (TLC-FID) and Gas chromatography with flame ionization detection for the dete...

We propose a fast silent self-stabilizing building a k-independent dominating set, named FID. The convergence of protocol FID, is established for any computation under the unfair distributed scheduler. FID reaches a terminal (also legitimate) configuration in at most 4n+k rounds, where n is the network size. FID requires (k + 1)log(n+ 1) bits per node. keywords distributed computing, fault tole...

BACKGROUND Flow-induced vasodilation (FID) is a physiological mechanism for regulating coronary flow and is mediated largely by nitric oxide (NO) in animals. Because hyperpolarizing mechanisms may play a greater role than NO in the microcirculation, we hypothesized that hyperpolarization contributes importantly to FID of human coronary arterioles. METHODS AND RESULTS Arterioles from atria or ...
