    Notes: Abstract The synthetic image generation with the lens effect consists of two consecutive processors: the hidden-surface processor, and the focus processor. The normal ray-tracing algorithms are used in the first processor. The second processor computes Lommel's function, which is an infinite series of Bessel functions. In order to avoid the complicated calculation and the huge memory consumption, an approximation method based on the light particle theory is developed. No noticeable differences can be detected between the results from the approximation method and those from the exact calculation.

    Notes: Abstract Free radical generation is hypothesized to be the cause of alcohol-induced tissue injury. Using fluorescent cis-parinaric acid and TBARS, lipid peroxidation was shown to be increased in the presence of trace amounts of free ferrous ion in PC12 cells. This increase in lipid peroxidation was enhanced by ethanol in a dose dependent manner and also correlated with loss of cell viability, as measured by increased release of lactate dehydrogenase (LDH). Resveratrol, a potent antioxidant, had a protective effect against lipid peroxidation and cell death. These findings strongly suggest that ethanol-induced tissue injury and cell death is a free radical mediated process, and may be important in alcohol-related premature aging and other degenerative diseases.
