Hydrothermal-electrochemical deposition of hydroxyapatite

Age-related differences in the trajectories of saccadic eye movements were examined. Younger and older adult subjects produced saccades to predictable target locations. Detailed features of the movements were examined such as the time of peak acceleration and the variability in the magnitude of the peak velocity. These and other measures reveal important details of the force pulses underlying the eye movements and the mental mechanisms that control them. Although minor differences were apparent between the eye movements of younger and older adults, the general patterns were the same across age groups. These results suggest that fundamental details of the brain mechanisms involved in the control of movement are the same for younger and older adults.     

Thin films of triglycine sulfate by laser evaporation

Thin films of triglycine sulfate were prepared by laser evaporation. The properties of these films were evaluated by electrical measurements, x-ray diffraction and IR spectrometry. The deposited material was found to be essentially triglycine sulfate with some glycine present as a decomposition product. The deposited material was also found to be highly oriented with the pyroelectric direction lying in the plane of the film.     

Radioactivity induced in a 2.5 GeV electron beam dump

The saturation activity of residual nuclei was estimated based on measurements when 2.5 GeV electron beams were totally absorbed in thick Al, Fe, Cu and Pb. A calculation was also made for a beam dump from 0.1 to 10 GeV using the EGS4 and PICA95 Monte Carlo codes. Above 1 GeV, the activity was constant in units of MBq.W-1. The gamma ray dose rates from the targets were calculated using these data.
