Bay region distortions in cyclopenta[a]phenanthrenes.
Two newly synthesized cyclopenta[a]phenanthrenes, namely the 1-methyl (VIII) and 7,11-dimethyl (VII) derivatives of the parent ketone 15,16-dihydrocyclopenta[a]phenanthren-17-one (I), have been tested for their capacity to produce skin tumors in mice. The former (VIII) is essentially inactive, whereas the latter (VII) is very potent in both repeated application and two-stage tests. X-ray crysta...
متن کاملHuman visual perception of region warping distortions
This paper presents human visual perception experiment results for a computer graphics rendering technique introduced in ACSC’05. In order to achieve a good immersive virtual reality experience, it is necessary to have at least 60 frames per second to ensure smooth motion. It is also necessary to have low end-to-end latency so that user interaction does not suffer from perceptible delays in ima...
متن کاملPopulation structure, growth and production of a recent brachiopod from the Chilean fjord region
38 39 Magellania venosa, the largest recent brachiopod (Davidson 1886, McCammon 1973), 40 occurs in clusters and banks in population densities of up to 416 ind m-2 in the fjord Comau, 41 northern Chilean fjord region. Below 15 m depths, it co-occurs with the mytillid Aulacomya 42 atra and dominates the benthic community below 20 m. To determine the question why 43 Magellania venosa is a success...
متن کاملUnrepaired fjord region polycyclic aromatic hydrocarbon-DNA adducts in ras codon 61 mutational hot spots.
The fjord region diol-epoxide metabolites of polycyclic aromatic hydrocarbons display stronger tumorigenic activities in rodent studies than comparable bay region diol-epoxides, but the molecular basis for this difference between fjord and bay region derivatives is not understood. Here we tested whether the variable effects of these genotoxic metabolites of polycyclic aromatic hydrocarbons may ...
متن کاملPerceptual Distortions
This research project attempts to quantify the subjective quality of color vision that artists like Josef Albers have explored through their art. It is widely understood by artists and scientists that the appearance of a surface color is affected by its context. However, there are many questions yet to be answered about the specific spatial relationships between colors. This experiment uses an ...
