Magnetic resonance imaging of wood
Canadian Journal of Forest Research, 1986 A magnetic resonance scanner has been used to obtain images at 0.14 T, based on the water in aspen (Populustremuloides Michx.). In addition to visualization of the expected structural features such as annual growth-rings and knots, several additional features appear that require further study.

Detection of a period decrease in NN Ser with ULTRACAM: evidence for strong magnetic braking or an unseen companion? [PDF]
, 2005 We present results of high time resolution photometry of the eclipsing pre-cataclysmic variable NN Ser. We observed 13 primary eclipses of NN Ser using the high-speed CCD camera ULTRACAM and derived times of mid-eclipse, from fitting of light curve ...

A Unilateral Nuclear Magnetic Resonance Sensor for Nondestructive Wood Moisture Measurements
Chinese Journal of Magnetic Resonance, 2017 An unilateral nuclear magnetic resonance (UMR) sensor was designed to measure wood moisture nondestructively. The sensor consisted of a unilateral magnet, an anti-eddy current module, a radiofrequency (RF) coil and an impedance matching and tuning ...

Environmental effect of co-firing and magnetic field on wood pellets combustion
Journal of Environmental Engineering and Landscape Management, 2014 The aim of the recent research is to provide stable, controllable and effective wood pellets combustion with minimum emissions. Two possibilities were chosen, investigated and analysed: wood pellets co-firing with propane-butane mixture and the use of a ...

On the Low and High Frequency Correlation in Quasi-Periodic Oscillations Among White Dwarfs, Neutron Star and Black Hole Binaries [PDF]
, 2002 We interpret the correlation over five orders of magnitude between high frequency and low frequency in a quasi-periodic oscillations (QPO) found by Psaltis, Belloni & van der Klis (1999) for black hole (BH), neutron star (NS) systems and then extended by
