Thermal Stability of Ag/Bi-2212 Tape at Cryocooled Condition.

Cryocooled sapphire oscillator with ultrahigh stability

We present design details and test results for the first short-term frequency standard to achieve ultra-high stability (oy < without he use of liquid helium. Technical features include vibration isolation by atmospheric helium gas and a new sapphire resonator design with adjustable compensation operating at 8-10K.

Vibrational stability of a cryocooled horizontal double-crystal monochromator

The vibrational stability of a horizontally deflecting double-crystal monochromator (HDCM) is investigated. Inherently a HDCM will preserve the vertical beam stability better than a `normal' vertical double-crystal monochromator as the vibrations of a HDCM will almost exclusively affect the horizontal stability. Here both the relative pitch vibration between the first and second crystal and the...

Improvement of Thermal Stability of BCG Vaccine

Background: Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer...

Detection of a multi - phase ISM at z = 0 . 2212

We present sensitive Giant Metrewave Radio Telescope (GMRT) and high-resolution Arecibo HI 21-cm observations of the damped Lyman-α absorber (DLA) at z = 0.2212 towards OI 363 (B2 0738+313). The GMRT and Arecibo spectra are in excellent agreement and yield a spin temperature Ts = 890 ± 160 K, consistent with earlier lower sensitivity observations of the system. This value of Ts is far higher th...
