Formation of uniaxial molecular films by liquid-crystal imprinting in a magnetic field

Scanning tunneling microscopy was used to study molecular order in monolayer organic films formed by solution-phase growth from thermotropic liquid crystal solvents. The films develop macroscopically uniaxial alignment, with adlayer orientation controlled by an external magnetic field through interactions mediated by the liquid crystal. Results are presented for two films deposited from nematic and smectic- A solvents, along with a discussion of the alignment mechanism.

Jog your memory: a community screening model.

This study's objectives were to establish an annual memory-screening week, heighten public awareness of the issues surrounding cognitive impairments, promote baseline cognitive screening as part of routine examinations in primary care settings for the older adult, and detect early dementia and depression. The 264 participants completed demographic and anecdotal information and the Geriatric Depression Scale (GDS). Nurses scored the GDS and administered the Mini Mental State Examination (MMSE) and the Clock Drawing Test. Screening results and educational information were given to the participants. Results revealed that 14% of participants scored abnormally on the MMSE and approximately 14% had an abnormal GDS score.
