The transport properties of domain walls in oxygen deficient multiferroic YMnO3 single crystals have been probed using conductive atomic force microscopy and piezoresponse microscopy. Domain exhibit significantly enhanced conductance after being poled electric fields, possibly induced by vacancy ordering at walls. electronic conduction can be understood the Schottky emission Fowler-Nordheim tunnelling mechanisms. Our results show that wall modulated through band structure engineering...
The authors propose a new ultrasonic image analysis system that can be utilized as an effective tool in classifying liver states normal, hepatitis, or cirrhosis. In this system, the first define suitable settings for device, then remove inhomogeneous structures from area of interest image, and then, by using forward sequential search method, look useful texture parameters co-occurrence matrix, statistical feature spectrum, fractal dimension descriptors. Finally, selected are fed into...
Young's Modulus was measured on the trachea and first three generations of pig airways by compression. A simple low-cost system for measuring elastic properties small bio-materials is presented. The force-displacement measurements have been undertaken dissected cartilage mucosa from bronchial segments. wall, 1.78 ± 0.51 MPa, found to be dominated value 1.74 0.85 MPa while modulus 0.15 0.03 MPa. airway wall bronchi decreases 1.35 0.17 0.35 0.10 which also cartilage. Airway similar 0.036 0.005 airways.
Objective: Gradiometers have the advantage of increasing measuring sensitivity, which is particularly useful in magnetic induction spectroscopy (MIS) for bio-impedance measurements. Traditional gradiometers use a pair field sensing coils equally distant and on opposite sides drive coil, provides high immunity to interference. In this paper, ferrite-cored coaxial gradiometer probe 29 mm diameter has been developed impedance spectra cervical tissues vivo. Approach: It consists ferrite rod with...
Young's Modulus and dynamic force moduli were measured on human bronchial airway tissues by compression. A simple low-cost system for measuring the tensile-strengh of soft bio-materials has been built this study. The force-distance measurements undertaken dissected walls, cartilages mucosa from surgery-removed lungs donated lung cancer patients with COPD. modulus is estimated initial slope unloading force-displacement curve (storage loss) are at low frequency (from 3 to 45 Hz). All samples...
A high-speed atomic force microscope for scanning large areas, utilizing a quartz bar driven close to resonance provide the motion in fast scan axis is presented. Images up 170 × μm2 have been obtained on polydimethylsiloxane (PDMS) grating 1 s. This provided through an average tip-sample velocity of 28 cm s-1 at line rate 830 Hz. Scan areas 80 0.42 s with 1410 To demonstrate capability scanner spherulitic crystallization semicrystalline polymer was imaged situ high speed.
Multiple-breath-washout (MBW) measurements are regarded as a sensitive technique for lung function studies which can reflect the ventilation inhomogeneity of our respiratory airways [7,8,9]. Typically nitrogen is used tracer gas and washed out by pure oxygen in multi-breath-nitrogen (MBNW) washout tests. In this work, instead using nitrogen, 4He gas. A commercial quartz tuning fork with resonance frequency f-32 kHz has been detecting concentration at room temperature. This low-cost sensor...
