Anisotropy of water diffusion in axon tracts, as determined by diffusion-weighted MRI, has been assumed to reflect the restriction across membranes. Reduction this anisotropy interpreted degeneration axons. These interpretations are based primarily on a priori reasoning that had little empirical validation. We used experimental advantages sea lamprey spinal cord, which contains several very large axons, determine whether intraaxonal is isotropic and attributable mobility surface Through...
Surface charge accumulation on insulators under high dc voltage is a major factor that may lead to the reduction of insulation levels in gas insulated devices. In this paper, disc made Al2O3-filled epoxy resin were surface fluorinated using F2/N2 mixture (12.5% F2) at 50 °C and 0.1 MPa for different durations 15 min, 30 min 60 min. A was applied insulator density its measured by an electrostatic probe. The results revealed significant lower densities comparison with original one....
Surface charge decay kinetics on corona-charged polymeric insulators were studied. In the experiment, sample surface exposed to corona was kept open ambient air whereas opposite in contact with a grounded plate. The resulting potential distribution scanned raster mode using Kelvin electrostatic probe, from which relief map of density obtained by an inverse calculation method. developed procedure allowed for implementation two study cases: (i) gas neutralization took place under natural...
This paper is a sequel to the 1998 review “Scientific status of Dense Plasma Focus” with 16 authors belonging nations, whose initiative led establishment International Center for Magnetized Plasmas (ICDMP) in year 2000. Its focus on understanding principal defining characteristic features plasma light developments that have taken place last 20 years, terms new facilities, diagnostics, models, and insights. Although it too soon proclaim certainty what phenomenon is, results available date...
An experimental study on microwave plasma at atmospheric pressure was conducted by employing optical emission spectroscopy. Based a generation device developed for nanoparticle synthesis, we studied the influence of input power and gas flow rate behaviors electron temperature using Ar, He, N2 as working gas, respectively. The physics behind these discussed. results are useful in characterizing can be used improving synthesis system commercial use future.
The gas temperature is a key parameter that affects the process of microwave plasma chemistry in industrial applications. Based on molecular emission spectrometry A2Σ+→X2Πr electronic system OH radicals, atmospheric air core at different absorbed power levels, flow rates, humidities, and volume fractions CO2 was analyzed. In experiment, power, rate, humidity, ratio varied from 560 to 1750 W, 10 24 l min−1, 30% 95%, 0% 40%, respectively. Moreover, axial distribution torch measured....
ABSTRACT We studied possible mechanisms for the twofold difference in red muscle relaxation times between posterior (207.2 ms) and anterior (98.4 musculature of scup Stenotomus chrysops, which has been shown to have a large effect on power generation during swimming. This was not due contamination bundles with faster fiber types, as histological examination showed that all contained more than 98.9 % fibers. Further, maximum velocities shortening (Vmax) at 20 °C were nearly identical, 5.37 ML...

In addition, method producing some relevant observations are also provided. It is expected research would be useful for further developing sources expanding scope...
A relatively simple and economical method to prepare linear long‐chain dextrin (LLD) was created, with a resulting product that could act as high‐amylose starch for variety of downstream applications. Native cassava chosen the starting material due its inexpensive price low‐gelatinization temperature. pretreatment NaOH solution applied increase susceptibility pullulanase attack. The apparent amylose content final LLD extremely high (above 90%), determined by iodine binding colorimetric...
To provide polypropylene random copolymer (PPR) with excellent toughness without lowering its rigidity, a novel kind of core-shell particles (CSP) and β nucleating agent (β-NA) were incorporated into PPR by melt blending.

Plasmas under atmospheric pressure offer a high-temperature environment for material synthesis, but electrode ablation compromises purity. Here, we introduce an atmospheric-pressure microwave plasma (AMP) operated without electrodes to overcome the existing limitations in pure synthesis. The distribution of electrostatic field intensity inside waveguide during AMP excitation was examined via simulations. lateral and radial gas temperature distributions were also studied using optical...
