Effect of optical purity on phase sequence in antiferroelectric liquid crystals

, 2004
We use the discrete phenomenological model to study theoretically the phase diagrams in antiferroelectric liquid crystals (AFLCs) as a function of optical purity and temperature.

A Study of the Populations of X-ray Sources in the Small Magellanic Cloud with ASCA [PDF]

, 2000
The Advanced Satellite for Cosmology and Astrophysics (ASCA) has made multiple observations of the Small Magellanic Cloud (SMC). X-ray mosaic images in the soft (0.7--2.0 keV) and hard (2.0--7.0 keV) bands are separately constructed, and the latter ...

PARAMETERIZED EXERCISES IN SMC [PDF]

ICERI proceedings, 2016
The authoring of parameterized exercises has been a useful activity both for teachers, who could take advantage of databases of parameterized exercises for preparing study materials, but also for students that learn by producing new problems. This has been verified during the realization of MSc dissertations written by High School teachers that, as ...
