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
The purpose of the contract is to produce and purchase the various optics that make up the cryogenic spectrograph module and the cassegrain module of the spip instrument (infrared spectropolarimeter
pic du midi).
