We report results of experiments designed to test the use of thin magnetic films as elements of a neutron spin echo (NSE) apparatus for determining neutron scattering angles.
As described in one historical account, the party hardline Natolin faction "used anti-Semitism as a political weapon and found an echo both in the party apparatus and in society at large, where traditional stereotypes of an insidious Jewish cobweb of political influence and economic gain resurfaced, but now in the context of 'Judeo-communism,' the Żydokomuna".
The reflected echoes are received by an electronic apparatus that determines the intensity level of the echoes and the position of the tissue giving rise to the echoes.
This fits thematically with the 2008 report's call for a downsized, computerized, and more efficient military apparatus -- basically echoing the nascent mantra of 'technology and sustainability' as saviors of our way of doing business.
The proposed apparatus can detect a clear Hahn echo or Carr Purcell Meiboom Gill (CPMG) echoes of a pencil eraser block or a bottle of oil placed on the apparatus in 5 s with signal averaging using an RF transmitter power of only 19 W; the detection range of the apparatus exceeds 6 mm.
Fat and lean body compositions were measured by nuclear magnetic resonance (NMR) on an Echo-MRI (magnetic resonance imaging) 100 apparatus (Echo Medical Systems, Houston, TX, USA).
The speed of sound has been measured up to 100 MPa and in the temperature range (293.15 353.15) K by using an apparatus based on a pulse echo technique working in transmission mode, and a correlation for this property was proposed.
The dual-echo EPI sequence was modified from the default single-shot GE-EPI of the Siemens apparatus to acquire images at the two echo times of 13 and 38 ms, which were determined as the shortest echo times possible.
The principle of the apparatus is employment of pulse-echo ultrasound acquisition to track the propagation of the shear wave and to measure its velocity.
A commercially available ultrasound apparatus (Vivid i, GE Vingmed, Horten, Norway) was employed for echo-cardiographic examinations using a standard phased 2.5 MHz multi-frequency transducer.
