Using the high-sensitivity NARVAL spectropolarimeter
installed at the Bernard-Lyot telescope at the Pic du Midi Observatory in France, a team of astronomers detected the effect of a magnetic field (known as the Zeeman effect) in the light emitted by Vega.
To compare the time behavior of energy release manifested by hard X-ray emission and derivative of soft X-ray emission with time profile of the pion-decay emission, we used, in addition to SONG data, the Solar Spectropolarimeter
(SPR-N)  data and GOES soft X-ray measurements.
Circular dichroism (CD) measurements were performed on a Jasco Model J-720 spectropolarimeter
(Japan Spectroscopic Co., Tokyo, Japan), using a quartz cell with a 1 mm light path length, thermostatically controlled with a Jasco Model 423S Peltier-type temperature controller, and a thermostated cell holder, interfaced with a thermostatic bath.
For circular dichroism (CD) spectroscopy, we used a J-715 spectropolarimeter
(Jasco) operating at 37[degrees]C; spectra were recorded at 0.8 g/L protein with a 10-mm cell path length.
A CD spectropolarimeter
, an extremely sensitive instrument capable of accurately measuring in the 190-170nm range, is used to determine the absorption difference.
Spectra were collected with an Olis DSM-20 spectropolarimeter
equipped with a CD 250 Peltier cell holder (Bogart, GA).
Circular dichroism experiments were collected using a JASCO J-815 CD spectropolarimeter
equipped with Peltier temperature control.
The CD spectra in the range of 195-240 nm were determined on a JASCO J-715 spectropolarimeter
(Jasco, Tokyo, Japan) at room temperature.
Circular dichroism (CD) measurements were performed at 25[degrees]C on a Jasco spectropolarimeter
, model J-815, equipped with a thermostatically-controlled cell holder under constant nitrogen flow after calibrating the instrument with (+)-10-camphorsulfonic acid.
CD spectra were measured on a J-815 spectropolarimeter
(Jasco), c=1.5 mg/mL in Me0H at room temperature, quartz cuvette of 0.1 cm path length.
The protein-folding conformation of native heart CK-MB and rCK-MB2 was analyzed by measuring their circular dichroism at 25[degrees]C on a JASCO J720 spectropolarimeter
